[0002] Round paper barrels are widely used in the packaging industry. The processing cost of round paper barrels is relatively low, and the production process is very simple. They are very convenient to use for packaging some tea or logistics. Generally, a paper hoop is adhesively fixed on the outer peripheral wall of the barrel body of the round paper barrel to reinforce the barrel body structure and position the barrel lid. For example, Chinese Patent with Application No. 202410305786.1 discloses a fully automatic outer hoop sleeving and marking line system for round paper barrels, and its attached drawings disclose a round paper barrel similar to the above. A large number of paper hoops need to be made with paper tubes in the early stage of assembly. At present, there is no automated equipment on the market that can automatically slit and cut a paper barrel into multiple paper hoops. In most cases, paper hoops are manually slit and made, resulting in low production efficiency, and it is difficult to precisely control the size and quality of the paper hoops. Therefore, improvement is needed. Summary of the Invention

[0004] At present, there is no automated equipment on the market that can automatically slit and cut a paper barrel into multiple paper hoops. In most cases, paper hoops are manually slit and made, resulting in low production efficiency, and it is difficult to precisely control the size and quality of the paper hoops.

[0005] This application provides a numerically controlled paper hoop slitter, adopting the following technical solutions:

[0006] A numerical control slitting machine for paper hoops, comprising a frame, a storage rack, a loading rack, a main shaft, a supporting inner mold, a moving chassis, a driving assembly, a clamping assembly, a rotating assembly, a pushing assembly and a movable slitting cutter head. The main shaft is fixed on the frame and arranged along the X-axis direction. The supporting inner mold is vertically connected to the outer end of the main shaft. The moving chassis is slidably assembled on the frame along the X-axis direction and is driven by the driving assembly to reciprocate. The driving assembly is arranged between the frame and the moving chassis. The clamping assembly and the rotating assembly are both installed in the moving chassis. The main shaft slidably penetrates through the moving chassis, the clamping assembly and the rotating assembly. The storage rack and the loading rack are both located on the same side of the frame. The round paper tube on the storage rack automatically rolls down to the loading rack from top to bottom. The pushing assembly is installed on the loading rack and is used to push the round paper tube onto the supporting inner mold. The movable slitting cutter head is installed on the frame and is located below the supporting inner mold. When the movable slitting cutter head abuts against the supporting inner mold, the round paper tube is slit into paper hoops. When the clamping assembly clamps the end of the round paper tube, it is driven by the rotating assembly to rotate around the main shaft and is driven by the driving assembly to move horizontally.

[0007] In an implementable technical solution of the present application, the driving assembly includes a moving motor and a belt pulley transmission structure. The moving motor is installed inside the frame. The belt pulley transmission structure is arranged on the frame.

A plurality of inner clamping blocks are slidably assembled radially on the circular bottom plate. A plurality of first springs are also arranged on the circular bottom plate. The first springs are arranged in one-to-one correspondence with the inner clamping blocks. The first springs are used to drive the inner clamping blocks to slide towards the outer periphery to abut against the inner peripheral wall of the round paper tube. A reset cylinder is also fixed inside the moving chassis. The reset cylinder is used to drive the inner clamping blocks to slide towards the center of the circle to unlock the clamped round paper tube.

[0009] In an implementable technical solution of the present application, the circular bottom plate is also elastically connected with a hollow baffle. The hollow baffle is arranged parallel to the circular bottom plate at an interval, and a second spring is arranged between the two. The hollow baffle is provided with hollow holes for a part of the inner clamping blocks to extend into the inside of the round paper tube.

[0010] In an implementable technical solution of the present application, the rotating assembly includes a rotating motor, a driving gear, and a driven gear disc.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] The round paper tubes on the storage rack automatically roll from top to bottom onto the feeding rack. Then, the pushing component is started to push the round paper tubes on the feeding rack onto the supporting inner mold until the end of the round paper tube abuts against the clamping component. Then, the clamping component is started to clamp and fix the end of the round paper tube. Then, the driving component is started to drive the moving chassis to move intermittently by a fixed distance step by step. The movable cutting knife disc is started to make the movable cutting knife disc gradually approach the supporting inner mold. Cooperating with starting the rotating component to drive the round paper tube to rotate, the round paper tube can be cut into paper hoops.

[0038] The following further describes the present application in detail with reference to the Figures 1-3 accompanying drawings.

[0039] The embodiments of the present application disclose a paper hoop numerical control slitter. Refer to Figures 1-3, the paper hoop numerical control slitter includes a frame 100, a storage rack 200, a loading rack 300, a main shaft 1, a supporting inner mold 2, a moving chassis 3, a driving assembly 4, a clamping assembly 5, a rotating assembly 6, a pushing assembly 7 and a movable slitting cutter head 8. The main shaft 1 is fixed on the frame 100 and arranged along the X-axis direction. The supporting inner mold 2 is vertically connected to the outer end of the main shaft 1. The moving chassis 3 is slidably assembled on the frame 100 along the X-axis direction and is driven by the driving assembly 4 to move reciprocally. The driving assembly 4 is arranged between the frame 100 and the moving chassis 3. Both the clamping assembly 5 and the rotating assembly 6 are installed in the moving chassis 3. The main shaft 1 slidably penetrates through the moving chassis 3, the clamping assembly 5 and the rotating assembly 6. The storage rack 200 and the loading rack 300 are both located on the same side of the frame 100. The round paper tube on the storage rack 200 automatically rolls from top to bottom onto the loading rack 300. The pushing assembly 7 is installed on the loading rack 300 and is used to push the round paper tube onto the supporting inner mold 2. The movable slitting cutter head 8 is installed on the frame 100 and is located below the supporting inner mold 2. When it abuts against the supporting inner mold 2, the round paper tube is slit into paper hoops. When the clamping assembly 5 clamps the end of the round paper tube, it is driven by the rotating assembly 6 to rotate around the main shaft 1 and is driven by the driving assembly 4 to move horizontally. Among them, an inclined unloading chute 9 is also arranged on the frame 100, and an unloading box 10 is also arranged on the front surface of the frame 100. The slit paper hoops slide automatically along the unloading chute 9 into the unloading box 10.

[0040] In this embodiment, the core structure of the movable slitting cutter head 8 is a circular cutter head driven by a servo motor. At the same time, the "movable" design can be understood as adding elastic structures such as torsion springs and springs to drive the circular cutter head to always have a tendency to approach the supporting inner mold 2.

[0041] In this embodiment, the driving assembly 4 includes a moving motor 41 and a belt pulley transmission structure 42. The moving motor 41 is installed inside the frame 100, and the belt pulley transmission structure 42 is arranged on the frame 100. The output shaft of the moving motor 41 drives one of the belt pulleys of the belt pulley transmission structure 42 to rotate, and the bottom of the moving chassis 3 is fixed to the belt of the belt pulley transmission structure 42.

[0042] The driving assembly 4 designed above has a simple structure, stable operation, convenient and precise control, and can accurately control the moving chassis 3 to move a preset distance, which is beneficial to ensuring that the sizes of the paper hoops obtained by each slitting are consistent.

[0043] In this embodiment, the clamping assembly 5 includes a circular bottom plate 51. A plurality of inner clamping blocks 52 are slidably assembled radially on the circular bottom plate 51. A plurality of first springs 53 are also arranged on the circular bottom plate 51. The first springs 53 are arranged in one-to-one correspondence with the inner clamping blocks 52. The first springs 53 are used to drive the inner clamping blocks 52 to slide along the outer circumference to abut against the inner peripheral wall of the round paper tube. A reset cylinder 54 is also fixed inside the moving chassis 3. The reset cylinder 54 is used to drive the inner clamping blocks 52 to slide towards the center of the circle to unlock the clamped round paper tube.

[0044] The circular bottom plate 51 is also elastically connected with a hollow baffle 55. The hollow baffle 55 is arranged parallel to the circular bottom plate 51 at an interval, and a second spring 56 is arranged between the two. The hollow baffle 55 is provided with hollow holes for a part of the inner clamping blocks 52 to extend into the inside of the round paper tube. The first springs 53 and the inner clamping blocks 52 are provided with 3 - 6 groups and are evenly and symmetrically arranged around the center of the circular bottom plate 51. In this embodiment, 4 groups are preferably used. The above-designed clamping assembly 5 has a firm and stable structure and is also relatively convenient to operate, and can quickly achieve the purpose of clamping and unlocking the round paper tube.

[0045] In this embodiment, the rotating assembly 6 includes a rotating motor 61, a driving gear 62 and a driven gear disc 63. The driven gear disc 63 is fixed on the circular bottom plate 51. The rotating motor 61 is fixed inside the moving chassis 3 and drives the driven gear disc 63 to rotate through the driving gear 62. The main shaft 1 sequentially penetrates through the driven gear disc 63, the circular bottom plate 51 and the hollow baffle 55. The above-designed rotating assembly 6 has a simple structure, stable operation, convenient and accurate control, and can stably drive the round paper tube to rotate.

[0046] In this embodiment, the pushing assembly 7 includes a pushing baffle 71 and a pushing cylinder 72. The pushing cylinder 72 is installed on the loading rack 300. The pushing baffle 71 is slidably assembled on the loading rack 300 along the X-axis direction. The pushing cylinder 72 is used to drive the round paper tube towards the supporting inner mold 2 to abut against the side surface of the moving chassis 3. The above-designed pushing assembly 7 has a simple structure, stable operation, convenient and accurate control, and can stably push the round paper tube to the slitting station.

[0047] To ensure the stability of the moving chassis 3 during horizontal sliding, at least two parallel and spaced guide rails 101 are arranged on the frame 100. Sliders 102 adapted to the guide rails 101 are arranged at the bottom of the moving chassis 3.

[0048] The working principle / usage process of the paper hoop numerical control slitter in the embodiment of the present application is roughly as follows:

[0049] The round paper tube on the storage rack 200 automatically rolls from top to bottom onto the loading rack 300. Then, the pushing component 7 is activated to push the round paper tube on the loading rack 300 onto the supporting inner mold 2 until the end of the round paper tube abuts against the clamping component 5. Next, the clamping component 5 is activated to clamp and fix the end of the round paper tube. Then, the driving component 4 is activated to gradually drive the moving chassis 3 to move intermittently by a fixed distance. The movable slitting cutter head 8 is activated to gradually approach the supporting inner mold 2, and the rotating component 6 is activated in cooperation to drive the round paper tube to rotate, so that the round paper tube can be slit into paper hoops. By repeating the slitting operation, the round paper tube can be gradually slit into multiple paper hoops of the required size.

[0050] The beneficial technical effects of the paper hoop numerical control slitting machine according to the embodiment of the present application are roughly as follows:

[0051] The overall structure is simple, the operation is stable and smooth, and the operation is convenient. The purpose of automatically slitting paper hoops can be efficiently achieved, and the size and quality of the paper hoops can be precisely controlled, greatly improving the production efficiency.

[0052] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the application shall be included in the protection scope of the present application.
