Description

Technical Field

[0001] This utility model relates to the field of paper product processing technology, specifically to a cutting and winding device for printed paper products. Background Technology

[0002] In the production process of printed paper products, cutting and winding are two crucial steps. The cutting step is responsible for cutting continuous paper products into the required length or shape, while the winding step is responsible for neatly winding up the cut paper products to facilitate subsequent processing, transportation, and use.

[0003] A search revealed a utility model patent with Chinese patent publication number CN210854614U, which discloses a printing paper winding device, including a base and a guide cylinder. A left column and a right column are provided on the top left and right sides of the base. A shock-absorbing seat is provided on one side of the right column and at one end of the base. An asynchronous motor is installed on the top of the shock-absorbing seat. A round rod is riveted to the output shaft of the asynchronous motor. A winding cylinder is rotatably connected to the round rod, and a first support rod is provided at the end of the round rod away from the asynchronous motor.

[0004] The aforementioned device uses a separate winding drum to wind up paper products. Once the paper products are wound to a certain extent, they need to be removed and a new winding drum needs to be installed to continue working. This process involves many steps, takes a long time, and cannot be done immediately, indicating room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a cutting and winding device for printed paper products to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a printing paper product cutting and winding device, including a mounting frame, an mounting assembly mounted on the top of the mounting frame, the mounting assembly including a flipping frame rotatably connected inside the mounting frame via bearings, a driven gear coaxially fixed at both ends of the rotating shaft of the flipping frame, a horizontally arranged gear rod rotatably connected inside the mounting frame via bearings, the gear rod meshing with two driven gears, and a motor fixedly mounted on the outer wall of one end of the mounting frame, the output end of the motor being coaxially fixed with one end of the gear rod.

[0007] After the rewinding roller finishes collecting the paper roll, it can be temporarily stored in another location. A new rewinding roller will then replace it, allowing for immediate rewinding and improving work efficiency. After rewinding is complete, the motor on the outside of the mounting frame is started. The output of the motor drives the gear rod to rotate, which in turn drives two driven gears to rotate. These two driven gears then rotate the flipping frame a quarter turn. The new rewinding roller will replace the paper roll. Simply re-secure the paper product to continue working. The paper roll can be disassembled during the rewinding process, making full use of the time.

[0008] As a further preferred embodiment of this technical solution, a winding assembly is installed at both ends of the flipping frame. The winding assembly includes a guide groove opened on the top outer wall of the flipping frame, a movable plate slidably connected inside the guide groove, and a drive sleeve rotatably connected to the movable plate and the inside of the flipping frame through a bearing. The two drive sleeves are symmetrically arranged. A second motor is fixedly installed on the outer wall of one end of the flipping frame, and the output end of the second motor is coaxially fixed with one end of one of the drive sleeves.

[0009] As a further preferred embodiment of this technical solution, a lead screw is rotatably connected inside the guide groove via a bearing, the movable plate is threaded onto the outside of the lead screw, and a handle is fixedly connected to one end of the lead screw.

[0010] As a further preferred embodiment of this technical solution, the mounting frame is equipped with two limiting components. The limiting components include two multi-stage telescopic rods fixedly connected to the inner wall of the bottom of the flipping frame. The top ends of the two multi-stage telescopic rods are fixedly connected to the same mounting base. The mounting base is rotatably connected to a roller through a bearing. The roller is located directly below the two drive sleeves. A spring is sleeved on the outside of each of the two multi-stage telescopic rods.

[0011] As the thickness of the paper product outside the winding roll increases, the paper product comes into contact with the roller, and then the elastic force of the spring is overcome and shortened. Its reaction force is applied to the surface of the paper roll through the mounting base and the roller. On the one hand, this makes the paper product more compact, and when one end of the paper product loses its restraint, the roller can press the surface of the paper product to prevent the paper roll from becoming loose due to elasticity.

[0012] As a further preferred embodiment of this technical solution, a horizontally arranged support frame is fixedly connected to the outer walls of both ends of the mounting frame, and the flipping frame is in contact with one of the support frames.

[0013] As a further preferred embodiment of this technical solution, a connection hole is provided at each of the four corners of the bottom inner wall of the mounting bracket.

[0014] As a further preferred embodiment of this technical solution, the transmission ratio between the gear rod and the driven gear is greater than one.

[0015] This utility model provides a cutting and winding device for printed paper products, which has the following beneficial effects:

[0016] (1) By setting up the installation components, this utility model can transfer the paper roll to another location for temporary storage after the winding roller has finished collecting it. The new winding roller will replace its position, and the winding can be started immediately, which is beneficial to improving work efficiency. After the winding work is completed, the motor one on the outside of the installation frame is started. The output end of the motor one drives the gear rod to rotate. The gear rod drives the two driven gears to rotate through meshing. The two driven gears can drive the flipping frame to rotate a quarter turn. The new winding roller will replace the position of the paper roll. As long as the paper product is re-fixed, the work can continue. The paper roll can be disassembled during the winding work, which can make full use of the time.

[0017] (2) By setting a limiting component, as the thickness of the paper product outside the winding roller increases, the paper product and the roller come into contact, and then the elastic force of the spring is overcome and shortened. Its reaction force is applied to the surface of the paper roll through the mounting seat and the roller. On the one hand, the paper product is more compact, and when one end of the paper product loses its restriction, the roller can press the surface of the paper product to prevent the paper roll from becoming loose due to elasticity.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 1 and Figure 3 As shown in this embodiment, a printing paper product cutting and winding device includes a mounting frame 1. A mounting assembly 4 is mounted on the top of the mounting frame 1. The mounting assembly 4 includes a flipping frame 401 rotatably connected to the inside of the mounting frame 1 via bearings. Both ends of the rotating shaft of the flipping frame 401 are coaxially fixed with a driven gear 402. A horizontally arranged gear rod 403 is rotatably connected to the inside of the mounting frame 1 via bearings. The gear rod 403 meshes with the two driven gears 402. A motor 404 is fixedly mounted on the outer wall of one end of the mounting frame 1. The output end of the motor 404 is coaxially fixed with one end of the gear rod 403.

[0025] Start the motor 404 on the outside of the mounting frame 1. The output of the motor 404 drives the gear rod 403 to rotate. The gear rod 403 drives the two driven gears 402 to rotate through meshing. The two driven gears 402 can drive the flipping frame 401 to rotate a quarter turn. The new winding roller will replace the paper roll. As long as the paper product is re-fixed, the work can continue. The paper roll can be disassembled during the winding operation, making full use of the time.

[0026] like Figure 2 and Figure 4 As shown, a winding assembly 5 is installed at both ends of the flipping frame 401. The winding assembly 5 includes a guide groove 501 opened on the top outer wall of the flipping frame 401, a movable plate 503 slidably connected inside the guide groove 501, and a drive sleeve 504 rotatably connected to the movable plate 503 and the flipping frame 401 through a bearing. The two drive sleeves 504 are symmetrically arranged. A second motor 505 is fixedly installed on the outer wall of one end of the flipping frame 401. The output end of the second motor 505 is coaxially fixed with one end of one of the drive sleeves 504.

[0027] Inside the guide groove 501, a lead screw 502 is rotatably connected via a bearing. A movable plate 503 is threaded onto the outside of the lead screw 502, and a handle is fixedly connected to one end of the lead screw 502.

[0028] When the motor 505 outside the flipping frame 401 is started, the output end of the motor 505 drives a drive sleeve 504 connected to it to rotate. With the help of another drive sleeve 504, the take-up roller can be driven to take up the printing paper. When the take-up roller needs to be removed, the screw 502 is rotated by the handle. The moving plate 503, which is restricted by the guide groove 501, moves away from the take-up roller under the drive of the screw 502, and then the take-up roller can be easily removed.

[0029] like Figure 2 and Figure 4As shown, two limiting components 6 are installed inside the mounting frame 1. The limiting components 6 include two multi-stage telescopic rods 601 fixedly connected to the bottom inner wall of the flip frame 401. The top end of the two multi-stage telescopic rods 601 is fixedly connected to the same mounting base 603. The mounting base 603 is rotatably connected to a roller 604 through a bearing. The roller 604 is located directly below the two drive sleeves 504. A spring 602 is sleeved on the outside of each of the two multi-stage telescopic rods 601.

[0030] As the thickness of the paper product outside the winding roll increases, the paper product comes into contact with the roller 604, and then the elastic force of the spring 602 is overcome and shortened. Its reaction force is applied to the surface of the paper roll through the mounting base 603 and the roller 604. On the one hand, this makes the paper product tighter, and on the other hand, when one end of the paper product loses its restraint, the roller 604 can press the surface of the paper product to prevent the paper roll from becoming loose due to elasticity.

[0031] like Figure 1 and Figure 3 As shown, a horizontally arranged support frame 2 is fixedly connected to the outer walls of both ends of the mounting frame 1. The flipping frame 401 is attached to one of the support frames 2. The support frame 2 can support the winding roller with paper roll, preventing the motor 404 from being unable to support it.

[0032] like Figure 1 As shown, each of the four corners of the bottom inner wall of the mounting bracket 1 has a connecting hole 3. By passing the bolt through the connecting hole 3, the mounting bracket 1 can be connected to the external equipment.

[0033] like Figure 3 As shown, the transmission ratio between the gear rod 403 and the driven gear 402 is greater than one. The gear rod 403 needs to rotate many times to drive the driven gear 402 to rotate once, thereby reducing the load on the motor 404.

[0034] This utility model provides a cutting and winding device for printed paper products, the specific working principle of which is as follows:

[0035] When the device is working, the second motor 505 outside the flipping frame 401 starts. The output end of the second motor 505 drives a drive sleeve 504 connected to it to rotate. In conjunction with the other drive sleeve 504, it drives the take-up roller to wind up the printing paper. When the take-up roller needs to be removed, the screw 502 is rotated by the handle. The moving plate 503, which is restricted by the guide groove 501, moves away from the take-up roller under the drive of the screw 502. Then the take-up roller can be easily removed. As the thickness of the paper product outside the take-up roller increases, the paper product comes into contact with the roller 604. Then the elastic force of the spring 602 is overcome and shortened. Its reaction force is applied to the surface of the paper roll through the mounting base 603 and the roller 604. On the one hand, it makes the paper product more compact, and when one end of the paper product is unrestrained, the roller 604 can press the surface of the paper product to prevent the paper roll from becoming loose due to elasticity. After the winding work is completed, the motor 404 on the outside of the mounting frame 1 is started. The output end of the motor 404 drives the gear rod 403 to rotate. The gear rod 403 drives the two driven gears 402 to rotate through meshing. The two driven gears 402 can drive the flipping frame 401 to rotate a quarter turn. The new winding roller will replace the position of the paper roll. As long as the paper product is re-fixed, the work can continue. The paper roll can be disassembled during the winding work, making full use of time.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
