Description

Technical Field

[0001] The utility model relates to the technical field of elastic cloth die-cutting, and more specifically, to an elastic cloth positioning die-cutting bottom roller. Background Art

[0002] In the prior art, during the die-cutting process of the elastic fabric, the elastic fabric is mostly fixed on the roller through the air suction holes on the roller surface.

[0003] However, since the elastic cloth material has a certain elasticity, and the suction force of the roller surface suction holes alone cannot completely resist the elasticity of the elastic cloth, after the elastic cloth is cut at the cutting point of the die-cutting knife, the elastic cloth will have different degrees of elastic expansion and contraction, which will make the final cut shape unable to be guaranteed, affecting the product yield.

[0004] Therefore, in order to solve the above technical problems, the present application proposes an elastic cloth positioning die-cutting bottom roller. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model aims to provide a bottom roller for positioning and die-cutting elastic cloth.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An elastic cloth positioning die-cutting bottom roller comprises: a mounting frame, an adjusting mechanism is mounted on the top surface of the mounting frame, a transmission gear shaft is movably mounted on the left wall of the adjusting mechanism through a bearing, a suction roller is movably mounted on the inner side of the mounting frame through a bearing, and a transmission gear ring is fixedly connected to the outer side of the left end of the suction roller;

[0008] A die-cutting structure is installed on the inner side of the mounting frame, and the die-cutting structure includes a rotating roller, which is movably mounted inside the bottom end of the adjusting mechanism through a bearing, and a cutting knife is engraved on the surface of the rotating roller. A rotating cylinder is movably mounted on the inner side of the mounting frame through a bearing, and air suction holes are opened on the surface of the rotating cylinder, and spheres are engraved on the surface of the rotating cylinder.

[0009] Preferably, a shielding structure is installed on the mounting frame, and the shielding structure includes a shield, and the shield is fixedly installed on the inner left wall of the mounting frame, the top surface of the shield is installed with a adding port, and the bottom surface of the shield is installed with a cleaning port.

[0010] Preferably, the transmission gear shaft is meshed with the transmission gear ring, and the transmission gear shaft, the rotating roller and the rotating drum are all driven by a driving device.

[0011] Preferably, the rotating roller cooperates with the rotating drum, and the surface of the cutter fits with the surface of the rotating drum.

[0012] Preferably, the cutter, the air suction hole and the ball are staggered, and there is a gap between the ball and the surface of the rotating roller.

[0013] Preferably, the mask is sleeved on the right end of the transmission gear shaft and the outer side of the transmission gear ring.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. In the utility model, a sphere is carved on the surface of the rotating drum so that the sphere protrudes from the surface of the rotating drum, does not contact the rotating roller, and is staggered with the cutter. When the elastic cloth is in transmission, the sphere can squeeze the elastic cloth, which can increase the contact friction between the elastic cloth and the rotating drum, so that the elastic cloth fits tightly with the rotating roller. With the suction force in the suction hole, the elastic cloth can be firmly fixed between the rotating roller and the rotating drum. After the elastic cloth is die-cut by the cutter, the elastic cloth can maintain its original shape, reduce deformation, and thus ensure the yield rate of the product;

[0016] 2. In the utility model, the transmission gear shaft is driven to rotate by the driving device, and the transmission gear shaft is meshed with the transmission gear ring. The rotation of the transmission gear shaft drives the suction roller to rotate through the transmission gear ring, thereby realizing the transmission of the elastic cloth in the device. Since the gear transmission is adopted, in order to reduce the friction force, lubricating liquid is applied to the transmission gear shaft and the transmission gear ring, and the transmission gear shaft and the transmission gear ring are located on one side of the suction roller. When the suction roller is used to drive the elastic cloth, the lubricating liquid on the transmission gear shaft and the transmission gear ring will adhere to the elastic cloth, so that the elastic cloth is affected. To prevent contamination, a mask is fixedly installed on the inner wall of the mounting frame, and the mask is arranged on the outside of the transmission gear shaft and the transmission gear ring, so as to shield the transmission gear shaft and the transmission gear ring, thereby preventing the elastic cloth from contacting with the transmission gear shaft and the transmission gear ring, thereby preventing the lubricating liquid on the transmission gear shaft and the transmission gear ring from adhering to the elastic cloth, thereby ensuring the quality of the elastic cloth, and lubricating liquid can be added to the transmission gear shaft and the transmission gear ring through the adding port, and the aged lubricating liquid can be discharged through the cleaning port, thereby ensuring the transmission smoothness of the transmission gear shaft and the transmission gear ring.

[0023] See also Figure 1-4 , the utility model provides an elastic cloth positioning die-cutting bottom roller embodiment:

[0024] The mounting frame 1, adjustment mechanism 11, transmission gear shaft 12, suction roller 13 and transmission gear ring 14 used in the present application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to technicians in this field, so they will not be repeated here.

[0025] An elastic cloth positioning die-cutting bottom roller comprises: a mounting frame 1, an adjusting mechanism 11 is mounted on the top surface of the mounting frame 1, a transmission gear shaft 12 is movably mounted on the left wall of the adjusting mechanism 11 through a bearing, a suction roller 13 is movably mounted on the inner side of the mounting frame 1 through a bearing, and a transmission gear ring 14 is fixedly connected to the outer side of the left end of the suction roller 13;

[0026] A die-cutting structure 2 is installed on the inner side of the mounting frame 1. The die-cutting structure 2 includes a rotating roller 21. The rotating roller 21 is movably installed inside the bottom end of the adjusting mechanism 11 through a bearing. A cutter 22 is engraved on the surface of the rotating roller 21. A rotating cylinder 23 is movably installed on the inner side of the mounting frame 1 through a bearing. A suction hole 24 is opened on the surface of the rotating cylinder 23. A ball 25 is engraved on the surface of the rotating cylinder 23. By engraving the ball 25 on the surface of the rotating cylinder 23, the ball 25 protrudes from the surface of the rotating cylinder 23, and the ball 25 does not contact the rotating roller 21, and is staggered with the cutter 22. When the elastic cloth is transmitted, the ball 25 can squeeze the elastic cloth, which can increase the contact friction between the elastic cloth and the rotating cylinder 23, so that the elastic cloth fits tightly with the rotating roller 21. With the suction force in the suction hole 24, the elastic cloth can be firmly fixed between the rotating roller 21 and the rotating cylinder 23. After the elastic cloth is die-cut by the cutter 22, the elastic cloth can maintain its original shape and reduce deformation, thereby ensuring the yield rate of the product.

[0027] Furthermore, a shielding structure 3 is installed on the mounting frame 1, and the shielding structure 3 includes a shield 31, which is fixedly mounted on the inner left wall of the mounting frame 1, and a adding port 32 is installed on the top surface of the shield 31, and a cleaning port 33 is installed on the bottom surface of the shield 31. The transmission gear shaft 12 is driven to rotate by a driving device, and the transmission gear shaft 12 is meshed with a transmission gear ring 14. The rotation of the transmission gear shaft 12 drives the suction roller 13 to rotate through the transmission gear ring 14, thereby realizing the transmission of the elastic cloth in the device. Due to the use of gear transmission, in order to reduce friction, lubricating liquid is applied to the transmission gear shaft 12 and the transmission gear ring 14, and the transmission gear shaft 12 and the transmission gear ring 14 are located on one side of the suction roller 13. When the suction roller 13 is used to drive the elastic cloth , the lubricating liquid on the transmission gear shaft 12 and the transmission gear ring 14 will adhere to the elastic cloth, causing the elastic cloth to be contaminated. By fixing the mask 31 on the inner wall of the mounting frame 1, the mask 31 is arranged on the outer side of the transmission gear shaft 12 and the transmission gear ring 14, so as to shield the transmission gear shaft 12 and the transmission gear ring 14, thereby preventing the elastic cloth from contacting with the transmission gear shaft 12 and the transmission gear ring 14, and further preventing the lubricating liquid on the transmission gear shaft 12 and the transmission gear ring 14 from adhering to the elastic cloth, thereby ensuring the quality of the elastic cloth, and lubricating liquid can be added to the transmission gear shaft 12 and the transmission gear ring 14 through the adding port 32, and the aged lubricating liquid can be discharged through the cleaning port 33, thereby ensuring the transmission smoothness of the transmission gear shaft 12 and the transmission gear ring 14.

[0028] Furthermore, the transmission gear shaft 12 is meshed with the transmission gear ring 14 , and the transmission gear shaft 12 , the rotating roller 21 and the rotating cylinder 23 are all driven by a driving device. The rotation of the transmission gear shaft 12 can drive the suction roller 13 to rotate through the transmission gear ring 14 .

[0029] Furthermore, the rotating roller 21 cooperates with the rotating cylinder 23 , and the surface of the cutter 22 fits with the surface of the rotating cylinder 23 , so that the elastic fabric can be die-cut by the cutter 22 .

[0030] Furthermore, the cutter 22 is staggered with the air suction hole 24 and the ball 25, and there is a gap between the ball 25 and the surface of the rotating roller 21. The setting of the air suction hole 24 and the ball 25 will not affect the die-cutting of the elastic cloth by the cutter 22. The ball 25 can fix the elastic cloth between the rotating roller 21 and the rotating cylinder 23 without crushing the elastic cloth, thereby ensuring that the elastic cloth remains intact after die-cutting and reducing deformation, thereby ensuring the yield rate of the product.

[0031] Furthermore, the mask 31 is sleeved on the right end of the transmission gear shaft 12 and the outer side of the transmission gear ring 14. The mask 31 can shield the transmission gear shaft 12 and the transmission gear ring 14, thereby preventing the elastic cloth from contacting the transmission gear shaft 12 and the transmission gear ring 14, and further preventing the lubricating liquid on the transmission gear shaft 12 and the transmission gear ring 14 from adhering to the elastic cloth, thereby ensuring the quality of the elastic cloth.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
