Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, in particular to a plastic packaging machine for book publishing. Background Art

[0002] When books are published, they need to be covered with a plastic film to protect them and prevent them from being contaminated during transportation, which would affect their sales.

[0003] The most common way to pack books is to use heat shrink film to plasticize them. During the packaging process, the plastic film can be put on the outside of the book and then put into the heat sealing machine for constant temperature heat sealing.

[0004] However, in the process of laminating books in conventional laminating and baling machines, the plastic film sleeve cannot be tightened after being attached to the outside of the book, which can easily lead to the laminating film being too large. This can easily leave gaps between the wrappings after heat sealing, making it impossible to provide adequate protection. Furthermore, the laminating film sleeve needs to be frequently replaced during the packaging process, and the roller core of the laminating film sleeve is connected by bolts, making disassembly cumbersome and affecting replacement efficiency. Therefore, there is a need to improve the existing technology. Utility Model Content

[0005] The utility model aims to provide a book publishing plastic packaging machine, which solves the problems that the plastic film is easily cut into too large pieces and the plastic film roller core is inconvenient to replace.

[0007] Preferably, both left and right ends of the heat sealing box are fixedly connected with curtains, and the curtains are in contact with the frame. The curtains can prevent heat loss inside the heat sealing box.

[0008] Preferably, the movable plate is slidably connected to the frame, and the thermal cutter is slidably connected to the frame, and the movable plate can drive the thermal cutter to move.

[0009] Preferably, one end of the spring 1 is fixedly connected to the movable plate, and the other end of the spring 1 is fixedly connected to the thermal cutter. The spring 1 can support the thermal cutter through elastic force.

[0010] Preferably, one end of the second spring is fixedly connected to the support plate, and the other end of the second spring is fixedly connected to the movable plate. The second spring can support the support plate through elastic force.

[0011] Preferably, the roller changing mechanism includes a limit plate, the outer side of the frame contacts the limit plate, the outer side of the frame is fixedly connected to a guide frame, the outer side of the guide frame is provided with a spring three, the outer side of the limit plate is fixedly connected to a pull ring, the side of the limit plate away from the pull ring is fixedly connected to the limit column, and a plastic film roller core is movably connected between the two limit plates, and the pull ring can drive the limit plate to move.

[0013] Preferably, one end of the spring three is fixedly connected to the limit plate, and the other end of the spring three is fixedly connected to the guide frame. The spring three can drive the limit plate to automatically reset through elastic force.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The utility model adds structures such as guide rods, support plates and rubber covers on the movable plate. During the process of wrapping books, the elastic force of the second spring can drive the support plate and the rubber cover to squeeze the plastic film on the outer side of the book. After squeezing, the plastic film can be tightened under the transmission force of the conveyor belt, thereby effectively reducing the amount of plastic film used and effectively improving the quality of book wrapping.

[0016] 2. The utility model adds structures such as a limit plate, a limit column and a guide frame to the frame. During use, the limit column of the limit plate can be driven by the elastic force of spring three to slide into the interior of the plastic film roller core to limit it. When disassembly and replacement are required, it is only necessary to separate the limit column from the plastic film roller core to release the limit on the plastic film roller core, thereby making it easier to replace the plastic film.
