Description

Technical Field

[0001] This utility model relates to the field of grinding head technology, and more specifically, to a grinding head machine for paper tube processing with positioning function. Background Technology

[0002] A paper tube grinding head machine is a piece of equipment used to process and trim paper tubes. This machine is typically used to trim the ends of paper tubes to make them flat and regular, and to ensure that the diameter and flatness of the tube openings meet the requirements. This equipment is commonly used in the paper products industry for manufacturing paper tubes, paper cores and similar products.

[0003] Chinese utility model patent CN213998834U discloses a grinding head machine for paper tube processing with positioning function. This grinding head machine is beneficial for grinding paper tubes, providing internal support to prevent deformation of the paper tubes due to their soft texture during grinding, and also facilitates clamping of the paper tubes for easier processing. However, the above patent has the following disadvantages in practical implementation: First, the equipment used for clamping the paper tubes is numerous and the cost is high; second, the process of clamping the paper tubes by personnel is relatively cumbersome. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a grinding head machine for paper tube processing with positioning function. It can reduce the equipment required to achieve the paper tube clamping function, effectively reduce the cost of use, and make the process of clamping paper tubes more convenient for personnel.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A grinding head machine for paper tube processing with positioning function includes a worktable. A support plate one and a support plate two are arranged on the worktable. A motor one is mounted on the left side wall of the support plate one, and a positioning disk is arranged on the right side wall of the support plate one. A drive shaft is fixedly connected to the power output end of the motor one. The positioning disk has a communicating annular cavity, three strip cavities, and a positioning hole. A gear is arranged in the annular cavity. The end of the drive shaft away from the motor one is fixedly connected to the gear. A positioning rod is arranged in each strip cavity, and the outer end of the positioning rod is slidably connected to a... A rack and pinion mechanism is used, with the rack meshing with a gear. An extension rod is fixedly connected to one end of the rack near the positioning hole, and an abutment block is fixedly connected to the other end of the extension rod away from the rack. The extension rod is slidably connected to the positioning hole. A paper tube is sleeved on the outer end of the positioning plate. A motor is mounted on the second support plate, and a drive shaft is fixedly connected to the power output end of the second motor. A grinding wheel is mounted on the drive shaft. This solution can reduce the equipment used to achieve the paper tube clamping function, effectively reduce the cost of use, and make the process of clamping the paper tube easier for personnel.

[0009] Furthermore, the positioning disc is a circular disc, and there is a certain gap between the positioning disc and the paper tube, which makes it easy to put the paper tube on the positioning disc before grinding the paper tube, so as to facilitate subsequent clamping operations.

[0010] Furthermore, the end of the abutment block furthest from the extension rod abuts against the paper tube. The abutment block is hemispherical, and a rubber layer is sleeved on the outer end of the abutment block. The shape of the rubber layer matches the abutment block. When performing an expansion clamping operation on the paper tube, when the rack moves towards the side closer to the positioning hole, it can drive the abutment block to abut against the inner wall of the paper tube, thereby clamping and fixing it. The rubber layer increases the friction between the abutment block and the paper tube, further ensuring the stability during clamping.

[0011] Furthermore, the three positioning holes are evenly distributed on the side wall of the positioning disk, and the spacing between the openings of adjacent positioning holes is consistent. When clamping the paper tube, the three abutment blocks extend from the positioning holes and can provide multi-directional support for the paper tube, thereby effectively improving the support effect and ensuring the stability of the paper tube after the abutment blocks clamp it in an expanded manner.

[0012] 3. Beneficial effects

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] (1) This solution can reduce the equipment used to achieve the paper tube clamping function, effectively reduce the cost of use, and make the process of clamping paper tubes easier for personnel.

[0015] (2) The positioning plate is a circular plate, and there is a certain gap between the positioning plate and the paper tube, so that the paper tube can be easily put on the positioning plate before the paper tube is ground, which facilitates the subsequent clamping operation.

[0016] (3) The end of the abutment block away from the extension rod abuts against the paper tube. The abutment block is set as a hemispherical shape. The outer end of the abutment block is covered with a rubber layer. The shape of the rubber layer matches the abutment block. When the paper tube is subjected to an expansion clamping operation, when the rack moves to the side closer to the positioning hole, it can drive the abutment block to abut against the inner wall of the paper tube, thereby clamping and fixing. The rubber layer increases the friction between the abutment block and the paper tube, further ensuring the stability during clamping.

[0017] (4) The three positioning holes are evenly distributed on the side wall of the positioning plate, and the spacing between the openings of adjacent positioning holes is consistent. When clamping the paper tube, the three abutment blocks extend from the positioning holes to provide multi-directional support for the paper tube, thereby effectively improving the support effect and ensuring the stability of the abutment blocks after the paper tube is expanded and clamped.

[0027] Example 1:

[0028] Please see Figure 1-4 A grinding head machine for paper tube processing with positioning function includes a worktable 1. A support plate 1 (first support plate 2) and a support plate 2 (second support plate 12) are mounted on the worktable 1. The support plate 1 (first support plate 2) is fixedly connected to the worktable 1, and the support plate 2 (second support plate 12) is slidably connected to the worktable 1 via an electric push rod. The connection method between the support plate 1 (first support plate 2), the support plate 2 (second support plate 12), and the worktable 1 is consistent with the opposite example. A motor 3 is mounted on the left side wall of the support plate 1 (first support plate 2), and a positioning disk 5 is mounted on the right side wall of the support plate 1 (first support plate 2). A drive shaft 4 is fixedly connected to the power output end of the motor 3. The positioning disk 5 has a connected annular cavity 501, three strip cavities 502, and a positioning hole 503. A gear 6 is installed in the annular cavity 501, and the drive shaft 4... One end away from the motor 3 is fixedly connected to the gear 6. A positioning rod 7 is provided in the strip cavity 502. A rack 8 is slidably connected to the outer end of the positioning rod 7, and the rack 8 meshes with the gear 6. An extension rod 9 is fixedly connected to the end of the rack 8 near the positioning hole 503. An abutment block 10 is fixedly connected to the end of the extension rod 9 away from the rack 8. The extension rod 9 is slidably connected to the positioning hole 503. A paper tube 11 is sleeved on the outer end of the positioning disk 5. A motor 13 is provided on the support plate 12. A drive shaft is fixedly connected to the power output end of the motor 13. A grinding wheel 14 is installed on the drive shaft. The other end of the paper tube 11 extends to the grinding wheel 14. The grinding wheel 14 is driven by the motor 13 to grind the paper tube 11.

[0029] The positioning plate 5 is a circular plate, and there is a certain gap between the positioning plate 5 and the paper tube 11, so that the paper tube 11 can be easily put on the positioning plate 5 before the paper tube is ground, which facilitates the subsequent clamping operation.

[0030] Please see Figure 1 and Figure 3 The end of the abutment block 10 away from the extension rod 9 abuts against the paper tube 11. The abutment block 10 is set in a hemispherical shape, and a rubber layer is sleeved on the outer end of the abutment block 10. The shape of the rubber layer matches the abutment block 10. When the paper tube 11 is subjected to an expansion clamping operation, when the rack 8 moves to the side closer to the positioning hole 503, it can drive the abutment block 10 to abut against the inner wall of the paper tube 11, thereby clamping and fixing. The rubber layer increases the friction between the abutment block 10 and the paper tube 11, further ensuring the stability during clamping.

[0031] Please see Figure 2-3 Three positioning holes 503 are evenly distributed on the side wall of the positioning disk 5, and the spacing between the openings of adjacent positioning holes 503 is consistent. When clamping the paper tube 11, the three abutment blocks 10 extend from the positioning holes 503 to provide multi-directional support for the paper tube 11, thereby effectively improving the support effect and ensuring the stability of the abutment blocks 10 after the paper tube 11 is expanded and clamped.

[0032] Working principle: When using this equipment to fix and grind the paper tube 11, firstly, the paper tube is placed on the outer end of the positioning plate 5. Then, the motor 3 is reversed, causing the rack 8 to move on the positioning rod 7 towards the side closer to the positioning hole 503 until the abutment block 10 abuts against the paper tube 11. The abutment block 10, which abuts against the paper tube 11 in three directions, ensures the stability of the expansion clamping. Then, the electric push rod is controlled to push the support plate 12 towards the support plate 2, causing the paper tube 11 to move to the grinding wheel 14. Then, control motor 2 13 to drive grinding wheel 14 to grind paper tube 11; when paper tube 11 is unloaded, control motor 1 3 to rotate forward, so that rack 8 is reset and abutment block 10 returns to positioning hole 503. Then, control electric push rod to drive support plate 2 12 to reset. Finally, remove the ground paper tube 11. Compared with the prior art, this utility model can reduce the equipment used to achieve paper tube clamping function, effectively reduce the cost of use, and make the process of clamping paper tube more convenient for personnel.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
