Description

Automatic change segmentation paper tube coiling machine of loosing core Technical Field The utility model relates to the technical field of printing, papermaking and packaging machinery, in particular to an automatic sectional loose core paper tube rolling machine. Background In the industrial fields of printing, papermaking, packaging and the like, a paper tube is used as a common material supporting and packaging container and is widely applied to the production and processing processes of products such as films, adhesive tapes, woven tapes, roll paper and the like. Conventional paper tube manufacturing equipment typically employs a winding mechanism and a stationary mandrel to continuously wind the paper and manually or mechanically withdraw the paper tube from the mandrel after winding. However, the prior art has the defects and problems that the traditional paper tube manufacturing equipment mostly adopts an integral fixed mandrel, so that the contact area between the paper tube and the mandrel is larger. When paper is tightly wound into a cylinder, frictional resistance between the paper tube and the surface of the mandrel is increased sharply, so that larger external force is required to be applied when the core is pulled, the traditional equipment often depends on manual operation in the core pulling link, an operator needs to pull the mandrel manually to pull the core, and due to instabilities of operation experience and operation force, sudden impact and uneven stress in the paper tube extraction process are easily caused, and the risks of equipment damage and product reworking are increased. Disclosure of utility model The utility model aims to provide an automatic segmented loose core paper tube rolling machine so as to solve the problems in the background technology. The automatic sectional loose core paper tube rolling machine is characterized by comprising a rolling mechanism and a pulling mechanism, wherein the rolling mechanism comprises a rolling base, a mandrel, a rolling force piece, a positioning head and a sliding block, the mandrel is formed by a first pulling pipe and a second pulling pipe and is mutually connected to form the outer surface of the mandrel, the mandrel is rotationally arranged on the rolling base, the rolling force piece is arranged on one side of the mandrel and is used for driving the mandrel to rotate so as to roll paper into a cylindrical shape, the positioning head is arranged on the other side of the mandrel and is used for positioning and correcting the mandrel, the pulling mechanism comprises a pulling base, a sliding block, one end of the sliding block is connected with the mandrel, the pulling force piece is arranged on one side of the pulling base and slides on the pulling base through the sliding block which is driven by the linkage of the sliding power piece and a rotating screw rod, and the mandrel is pulled from the rolling base to the pulling base. Preferably, two rotatable drums are arranged below the mandrel, and the drums are arranged on the rolling base through inclined telescopic rods. Preferably, a limiting block is arranged on the rotary drum. Preferably, a supporting block is arranged between the rolling base and the drawing base, a supporting hole is formed in the supporting block, and the mandrel is slidably arranged in the supporting hole. Preferably, a drawing base is arranged between the first drawing pipe and the second drawing pipe. Preferably, the outer surface of the mandrel is subjected to low friction treatment or coated with a release coating so as to further reduce friction between the paper tube and the mandrel in the rolling and drawing processes and facilitate core pulling operation. The utility model has the beneficial effects that: According to the utility model, due to the adoption of the design of sectional extraction, the second extraction pipe is extracted later, and the low-friction treatment or the coating of the demoulding coating is carried out on the outer surface of the mandrel, so that the direct friction contact area between the paper pipe and the mandrel is greatly reduced, the friction force required to be overcome in the core pulling process is effectively reduced, and the core pulling process is ensured to be easier and smoother. According to the utility model, by the aid of the inclined telescopic rods, the two rotary drums arranged below the mandrel not only provide solid support for the lower part of the paper tube, but also guide the paper to be evenly spread and wound in the paper tube rolling process. The automatic rotation adjusting function of the rotary drum reduces local deformation caused by uneven tension or friction, ensures the rounding and uniformity in the paper tube rolling process, and improves the quality of finished products.
