Description

Technical Field

[0001] The utility model relates to the technical field of paper tube production, in particular to a multi-paper tube film wrapping device. Background Art

[0002] Paper tube production is a process involving multiple steps and processes. First, paper pulp needs to be injected into the molding mold on the paper tube core making machine. After vibration, compaction and other processes, the pulp is formed into a cylindrical paper tube core. The paper tube core is then cut by a cutting machine and then dried to remove moisture inside the paper tube to prevent deformation or damage during use. The paper tube quality is then inspected to ensure that it meets relevant standards and requirements. Qualified paper tubes will be packaged, usually in cartons, wooden frames, etc., to protect the paper tube from damage during transportation and storage.

[0003] In the current existing technology, during the production and storage of paper tubes, since paper tubes are paper products, they are easy to absorb moisture in the air. Especially in a high temperature and high humidity environment, if the paper tubes are exposed to the air, they will quickly absorb moisture and cause the strength to decrease, thereby affecting the quality of the paper tubes. Therefore, the staff is required to hold a film wrapping device to wrap the film around the outer surface of the paper tube until the film completely covers the outer surface of the paper tube. In this process, the labor intensity of the staff is relatively high, which affects the efficiency of paper tube production. Therefore, a multi-paper tube film wrapping device is proposed to solve the above problem. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The two driving rollers 6 are rotatably installed on the frame 1, the paper tubes 2 are placed on the top of the two driving rollers 6, and the lifting frame 3 is slidably installed on the frame 1.

[0022] In the implementation of this example, a lifting device 5 for controlling the up and down movement of the lifting frame 3 is provided on the frame 1, a connecting platform 7 is fixedly installed on the lifting frame 3, an electric push rod 8 is fixedly installed on the connecting platform 7, the connecting platform 7 includes a support frame and four locking bolts, the support frame is located on one side of the lifting frame 3, a mounting groove is provided inside the support frame, the electric push rod 8 is installed inside the mounting groove, one end of the locking bolt passes through the support frame and extends to the inside of the lifting frame 3, the locking bolt is connected to the internal thread of the lifting frame 3, which is convenient for the installation and stable operation of the electric push rod 8, The telescopic end of the movable push rod 8 is fixedly connected to a mounting frame 9, and a tube pressing roller 10 is rotatably installed inside the mounting frame 9 to limit the rotation position of the paper tube 2. A driving motor 11 is fixedly installed on the frame 1, and a transmission component 12 for driving one of the driving rollers 6 to rotate is provided at one end of the driving motor 11. The transmission component 12 includes a chain and two sprockets. The two sprockets are respectively fixedly installed on the output shaft of the driving motor 11 and the outer surface of one of the driving rollers 6. The chain is installed on the two sprockets to facilitate starting the driving motor 11 and using the chain to drive the driving roller 6 to rotate.

[0023] Among them, the lifting device 5 includes a threaded sleeve and a threaded column, the threaded sleeve and the threaded column are threadedly connected, one end of the threaded column is fixedly connected to the lifting frame 3, the threaded sleeve is rotatably installed on the frame 1, and a guide column with one end penetrating the frame 1 is fixedly installed at the bottom of the lifting frame 3, which is convenient for rotating the threaded sleeve and controlling the up and down movement of the threaded column, thereby achieving the control of the up and down movement of the lifting frame 3.

[0024] In addition, two slide bars are fixedly installed on the frame 1, and two slide grooves are provided on the lifting frame 3. The outer surface of the slide bar is slidably connected with the inner wall of the slide groove to limit the moving track of the lifting frame 3.

[0025] By adopting the above technical solution, the paper tube 2 is placed on the two driving rollers 6, and then the staff manually pulls the film on the film wrapping device 4 from above the paper tube 2 to between the paper tube 2 and the driving roller 6. Then the production staff starts the start button of the device. At this time, the electric push rod 8 on the lifting frame 3 controls the installation frame 9 to move the tube pressing roller 10 downward, so that the paper tube 2 is pressed by the tube pressing roller 10, and then the driving motor 11 drives the driving roller 6 to rotate through the chain in the transmission assembly 12, thereby driving the paper tube 2 on the two driving rollers 6 to rotate, so that the film is also wrapped around the paper tube.

[0026] In the implementation of this example, a lead screw is rotatably installed on the frame 1, and the film wrapping device 4 is threadedly installed on the lead screw. One end of the lead screw is fixedly connected to an asynchronous motor, and the asynchronous motor is fixedly installed on the frame 1.

[0027] By adopting the above technical scheme, the film wrapping device 4 is driven by the rotation of the lead screw to move to one side. When the photoelectric switch detects that the film wrapping device 4 moves to the contact point of the two paper tubes, the film wrapping device 4 stops moving, and the film winding continues and is wound several more times at this position. When the photoelectric switch detects that the film wrapping device 4 moves to the other side, the film wrapping device 4 stops moving, and the driving motor 11 delays until the wrapping film is wound three times before stopping. The electric push rod 8 controls the tube pressing roller 10 to rise, and the film coating operation of the paper tube 2 is completed. After the production personnel cuts off the wrapping film, the paper tube 2 can be transferred and the next paper tube 2 coating operation can be carried out.

[0028] The working principle of the above embodiment is:

[0029] When the multi-paper tube film wrapping device is in use, the paper tube 2 is placed on two driving rollers 6, and then the staff manually pulls the film on the film wrapping device 4 from above the paper tube 2 to between the paper tube 2 and the driving roller 6. Then the production staff activates the start button of the device. At this time, the electric push rod 8 on the lifting frame 3 controls the installation frame 9 to move the tube pressing roller 10 downward, so that the paper tube 2 is pressed by the tube pressing roller 10. Then the driving motor 11 drives the driving roller 6 to rotate through the chain in the transmission assembly 12, thereby driving the paper tube 2 on the two driving rollers 6 to rotate, so that the film is also wound on the paper tube. Then the film wrapping device 4 is driven to move to one side by the rotation of the screw. When the photoelectric switch detects that the film wrapping device 4 moves to the contact point of the two paper tubes, the film wrapping device 4 stops moving, and the film winding continues and is wound several more times at this position.

[0030] When the photoelectric switch detects that the wrapping device 4 has moved to the other side, the wrapping device 4 stops moving, the driving motor 11 delays until the wrapping film is wrapped three times and then stops rotating, the electric push rod 8 controls the tube pressing roller 10 to rise, and the paper tube 2 laminating operation is completed. After the production staff cuts off the wrapping film, the paper tube 2 can be transferred and the next paper tube 2 laminating operation can be carried out.
