Abstract
Description
Technical Field
[0001] This utility model relates to the field of fabric finishing technology, specifically a direct cutting mechanism. Background Technology
[0002] In the production and processing of emergency blankets, the raw materials are generally folded into the desired shape, then extruded and molded. Finally, the extruded and molded raw materials are cut and then transported through the finished product conveyor platform. However, in actual use, we have found that the gaps between the traction rollers of the existing equipment are too large, which prevents the emergency blanket material from being properly connected when it is conveyed to the next process area. In addition, after the emergency blanket is cut, due to static electricity generated during the cutting process, the characteristics of the emergency blanket material itself, or the cutting method, the emergency blanket is often prone to tangling at the last set of traction rollers. This not only affects the subsequent production process, causing the production line to stop and delay, but may also damage the integrity of the emergency blanket, making it unable to achieve the expected use effect. Therefore, based on the above two points, we will improve the current equipment to meet the usage requirements. Utility Model Content
[0003] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a direct cutting mechanism that avoids the failure of emergency blanket material to be connected due to excessive gap between traction rollers and prevents the emergency blanket material from tangling during discharge.
[0004] The technical problem to be solved by this utility model is achieved through the following technical solution: a direct cutting mechanism, which includes a frame, on which are arranged in sequence according to the discharge direction; A pair of traction rollers I, which are rotatably mounted on the frame; A pair of traction rollers II are rotatably mounted on the frame and located at the discharge port of traction roller I; The direct cutting assembly includes a cutting roller and a knife roller rotatably mounted on the frame and located at the discharge port of the traction roller II. A cutter for cutting the emergency blanket is fixedly mounted on the outer circumferential surface of the knife roller, and the installation direction of the cutter is parallel to the axis of the knife roller. A pair of traction rollers III are rotatably mounted on the frame and located at the discharge port of the direct cutting assembly; It also includes a pair of auxiliary guide rollers I and a pair of auxiliary guide rollers II; A pair of auxiliary guide rollers I are rotatably mounted on the frame and located between the traction roller II and the direct cutting assembly; A pair of auxiliary guide rollers II are rotatably mounted on the frame and located between the direct cutting assembly and the traction roller III.
[0005] The technical problem to be solved by this utility model can also be achieved through the following technical solution: In the direct cutting mechanism described above, the axes of the traction roller I, traction roller II, cutting roller and guide roller, traction roller III, auxiliary guide roller I and auxiliary guide roller II are arranged vertically.
[0006] The technical problem to be solved by this utility model can also be achieved by the following technical solution: the direct cutting mechanism described above also includes a pair of material feeding rollers, which are rotatably mounted on the frame and located at the discharge port of the traction roller III, and a brush body is fixedly provided on the outer circumferential surface of the material feeding rollers.
[0007] The technical problem to be solved by this utility model can also be achieved through the following technical solution: in the direct cutting mechanism described above, the rotation direction of the material feeding roller is opposite to the rotation direction of the traction roller III.
[0008] The technical problem to be solved by this utility model can also be achieved through the following technical solution: In the direct cutting mechanism described above, the outer peripheral surfaces of the traction roller II and the traction roller III are connected by belt drive and have the same rotation direction, and the end of the traction roller III is gear driven to the end of the material handling roller and has the opposite rotation direction.
[0009] Compared with the prior art, the beneficial technical effects of this utility model are as follows: (1) We added auxiliary guide rollers I and II between the original traction rollers I, II and III. Auxiliary guide rollers I and II are located at the feed and discharge points of the cutting rollers and guide rollers in the direct cutting assembly, which makes the connection between the emergency blanket material and traction rollers II and III better before and after cutting. (2) The axes of traction roller I, traction roller II, cutting roller and guide roller, traction roller III, auxiliary guide roller I and auxiliary guide roller II are set vertically. Compared with the traditional horizontal setting, the vertically set rollers occupy less area. (3) By adding a material guide roller at the discharge point of traction roller III, when the material of the emergency blanket is wrapped around the outer circumference of traction roller III, the brush on the outer circumference of the material guide roller can brush the material of the emergency blanket attached to the outer circumference of traction roller III, so that the edge of the material of the emergency blanket is no longer attached to the outer circumference of traction roller III, thereby avoiding the phenomenon of the material of the emergency blanket being wrapped around.

[0012] The specific technical solutions of this utility model are further described below with reference to the accompanying drawings, so as to enable those skilled in the art to further understand this utility model, without constituting a limitation on its rights.
[0013] Example 1, referring to Figs. 1-2 A direct cutting mechanism includes a frame 1, which is formed by overlapping and welding of profiles, and is arranged sequentially on the frame 1 in the discharge direction; A pair of traction rollers I2 are rotatably mounted on the frame 1. This rotatable mounting, as described below, may be a rotary bearing. A pair of traction rollers II3 are rotatably mounted on the frame 1 and located at the discharge port of traction roller I2; The direct cutting assembly includes a cutting roller 4 and a knife roller 5 rotatably mounted on the frame 1 and located at the discharge port of the traction roller II 3. A cutter for cutting the emergency blanket 9 is fixedly mounted on the outer circumferential surface of the knife roller 5. The installation direction of the cutter is parallel to the axis of the knife roller 5. The cutter and the guide roller are designed to completely cut the emergency blanket 9 material. A pair of traction rollers Ⅲ6 are rotatably mounted on the frame 1 and located at the discharge port of the direct cutting assembly; To avoid the excessive distance between traction rollers II3 and III6 directly cutting the assembly, which would cause unstable material connection of the emergency blanket 9, we added a pair of auxiliary guide rollers I7 and a pair of auxiliary guide rollers II8. A pair of auxiliary guide rollers I7 are rotatably mounted on the frame 1 and located between the traction roller II3 and the direct cutting assembly; A pair of auxiliary guide rollers II8 are rotatably mounted on the frame 1 and located between the direct cutting assembly and the traction roller III6. The axes of the traction roller I2, traction roller II3, cutting roller 4, guide roller, traction roller III6, auxiliary guide roller I7, and auxiliary guide roller II8 are vertically arranged. It also includes a pair of feeding rollers 10, the feeding rollers 10 rotating in the opposite direction to the traction roller III6, and they are rotatably mounted on the frame 1 and located at the discharge port of the traction roller III6. The outer peripheral surfaces of the traction roller II3 and the traction roller III6 are connected by belt drive and rotate in the same direction. The power source of the belt can be an external rotary power mechanism such as a motor. The end of the traction roller III6 is gear driven to the end of the feeding roller 10 and rotates in the opposite direction. To prevent the material of the emergency blanket 9 from adhering to and wrapping around the outer peripheral surface of the traction roller III 6, a brush body is also fixed on the outer peripheral surface of the feeding roller 10. When the brush body on the feeding roller 10 comes into contact with the material of the emergency blanket 9 adhering to the outer peripheral surface of the traction roller III 6, the brush body on the outer peripheral surface of the feeding roller 10 can brush the material of the emergency blanket 9 adhering to the outer peripheral surface of the traction roller III 6, so that the edge of the material of the emergency blanket 9 no longer adheres to the outer peripheral surface of the traction roller III 6, thereby solving the problem of the material of the emergency blanket 9 getting tangled.
[0014] In Example 1, the direct cutting mechanism can be placed in the process area before or after folding, depending on the usage requirements. It receives the incoming material by relying on the traction roller I2. The emergency blanket 9 material passes through the traction roller II3, the auxiliary guide roller I7, the direct cutting assembly, the auxiliary guide roller II8, and a pair of traction rollers III6 in sequence. During this process, the brush on the material handling roller 10 can move the emergency blanket 9 material attached to the outer peripheral surface of the traction roller III6, so that the edge of the emergency blanket 9 material is no longer attached to the outer peripheral surface of the traction roller III6, thereby solving the problem of the emergency blanket 9 material getting tangled.
