Description

Heating device for plastic product production Technical Field The utility model relates to the field of plastic product production, in particular to a heating device for plastic product production. Background Plastic products are commonly called articles for life, industry and the like which are processed by adopting plastics as main raw materials. The plastic product production equipment is needed when the plastic product is produced, such as injection molding machine, plastic sucking machine and other equipment. When the existing injection molding machine is used, raw materials are conveyed into a material pipe through a conveying mechanism, the material pipe is heated through a heating ring installed on the surface of the material pipe, the raw materials in the material pipe are melted, then the melted raw materials are injected into a specified mold through an injection molding nozzle to be molded, the heating ring on the surface of the material pipe of the existing injection molding machine is formed by sleeving two groups of semicircular heating rings on the surface of the material pipe, and then the two groups of semicircular heating rings are connected together through bolts. However, the injection molding machine can vibrate during operation, the connecting bolts of the heating ring can be loosened due to long-time vibration, so that the heating ring is not tightly attached to the material pipe, the heating effect is reduced, the normal operation of the injection molding machine is affected, the connecting bolts of the heating ring are generally longer, the number of turns required to be screwed when the heating ring is replaced is excessive, and the working efficiency is affected. Disclosure of utility model The utility model aims to provide a heating device for plastic product production, which solves the problems in the background technology. The heating device for plastic product production comprises a material pipe, wherein a positioning clamping groove is formed in the surface of the material pipe; The heating ring, the heating ring surface is provided with the bottom plate, is provided with the lifter in the bottom plate, and the lifter surface cover is equipped with the lifter, and the lifter side is provided with the backup pad, and the backup pad side is provided with the gag lever post, and the lifter surface is provided with the limiting plate, and the constant head tank has been seted up on the bottom plate surface. Preferably, the positioning clamping grooves are provided with a plurality of groups, the positioning clamping grooves are linearly arranged at equal intervals relative to the surface of the material pipe, and one end of the limiting rod can be inserted into the positioning clamping grooves. Preferably, the bottom plate is fixedly connected to the surface of the heating ring, the heating ring is of an arc-shaped plate structure, and the two groups of heating rings can be aligned and sleeved on the material pipe in a circular ring shape. Preferably, the lifting groove is formed in the surface of the bottom plate, the movable groove is formed in the side face of the lifting groove, the lifting rod is fixedly connected to the surface of the lifting groove, and the limiting spring is sleeved on the surface of the lifting rod. Preferably, the lifting plate can vertically displace along the lifting rod, the supporting plate can vertically displace in the moving groove, and the supporting plate is of a square plate-shaped structure. Preferably, the lifting rod surface is provided with threads, the threads are in threaded connection with limit nuts, one end of each limit spring is fixedly connected to the surface of each limit nut, and the other end of each limit spring abuts against the surface of the lifting plate. Preferably, the limiting plate is fixedly connected to the surface of the lifting plate, a fixed clamping plate is arranged on the side face of the limiting plate, one end of the fixed clamping plate can be inserted into the positioning groove, and the fixed clamping plate is of a square plate-shaped structure. Compared with the prior art, the utility model has the beneficial effects that: When the heating device for plastic product production is used, the lifting plate is pulled to enable the fixed clamping plate to be inserted into the positioning groove, so that two groups of heating rings can be matched and fixed on the surface of the material pipe, then the heating rings are inserted into the positioning groove by the limiting rod, the problem that the heating rings slide on the surface of the material pipe is avoided, when the heating rings are needed to be replaced, the lifting plate can be pulled directly to enable the fixed clamping plate to be separated from the positioning groove, and when the limiting rod is separated from the positioning groove, the two groups of heating rings can be taken down from the material pipe.
