Description

Technical Field

[0001] This invention belongs to the field of cutting technology, specifically, it relates to a slitting device for bag processing materials. Background Technology

[0002] Suitcase shells are typically made from thermoplastic sheets using a vacuum forming process. Before vacuum forming, the rolled plastic sheet needs to be unrolled and cut into flat blanks of a fixed length that match the size of the vacuum forming mold, so that it can be fed into the heating station of the vacuum forming machine for softening and shaping.

[0003] CN209425515U discloses a rapid cutting device for thermoformed sheets, including a housing. Inside the housing is a crossbar with a groove at its upper end. Inside the groove is a third support rod, with a fixed box at the end of the third support rod furthest from the groove. Symmetrically arranged second support rods are arranged inside the groove. Symmetrically arranged first support rods are arranged on both sides of the upper end of the crossbar, with an operation box connected to the end of each first support rod furthest from the crossbar. A first protective cover is located on the upper left side of the housing, with a cylinder installed inside. One end of the cylinder is connected to a first connecting shaft, which passes through the first protective cover and connects to a connecting plate. The device measures and cuts the thermoformed sheet without manual operation.

[0004] Existing guillotine shearing or punching machines typically use a single fixed blade for continuous cutting. When cutting thermoformed sheet materials, the blade continuously rubs against the sheet, generating heat. Since a single blade cannot provide a cooling gap, heat accumulates at the blade edge. When the blade temperature exceeds the material's softening point, localized melting occurs at the cut edge. The molten material adheres to the blade surface, causing defects such as stringing, burrs, and weld beads in subsequent cuts. Operators must frequently stop the machine to clean the blade, reducing production efficiency. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] To address the issue raised in the background art where, during the cutting of thermoformed rolls, the blade continuously rubs against the sheet material, generating heat. Since a single blade cannot provide a cooling gap, heat accumulates at the blade edge. When the blade temperature exceeds the material's softening point, localized melting occurs at the cut edge. The molten material adheres to the blade surface, leading to defects such as stringing, burrs, and weld beads in subsequent cuts. Operators are forced to frequently stop the machine to clean the blade, reducing production efficiency. The present invention adopts the following technical solution.

[0011] Preferably, the conveying assembly includes a conveying roller, a first servo motor, a bottom support roller, and two second supports. The two second supports are detachably connected to both sides of the cutting support. The conveying roller and the bottom support roller are rotatably connected between the two second supports. The cutting support is provided with a through groove at the position of the conveying roller and the bottom support roller. The outer wall of one side of the second support is detachably connected to the first servo motor. The rotating end of the first servo motor is fixedly connected to one end of the conveying roller.

[0012] Preferably, the internal connection between the cutting blade holder and the cutting blade support is detachable. The clamping assembly includes two clamping plates, a sliding plate, and a second telescopic cylinder. The two second telescopic cylinders are detachably connected to the outer walls of both sides of the cutting blade support. The sliding plates on both sides are detachably connected to the telescopic ends of the two second telescopic cylinders on both sides, and the clamping plates on both sides are fixedly connected to the bottom of the sliding plates on both sides.

[0013] Preferably, the drive assembly includes an assembly frame, transmission rods, cams, a second servo motor, a first meshing gear, and a second meshing gear. The upper ends of the sliding mounting plates on both sides extend outward. The two ends of the T-shaped fixed mounting plate are detachably connected to the assembly frame. Transmission rods are rotatably connected to the left and right sides between the two assembly frames. Multiple cams are fixedly connected to the outer walls of the two transmission rods. The outer wall of one side of the assembly frame is detachably connected to the second servo motor. The rotating end of the second servo motor is fixedly connected to one end of one side of the transmission rod. The end of the two transmission rods away from the second servo motor passes through the other side of the assembly frame and is detachably connected to the first meshing gear. The outer wall of the other side of the assembly frame, located between the two first meshing gears, is rotatably connected to two mutually meshing second meshing gears. The first meshing gear meshes with the adjacent second meshing gear. The second servo motor has a built-in rotary encoder. The convex directions of the multiple cams on each transmission rod are consistent. The two transmission rods rotate in opposite directions. When one side cam pushes the corresponding sliding mounting plate down, the other side cam just moves away from the corresponding sliding mounting plate, realizing the alternating extension and retraction of the first cutting blade and the second cutting blade.

[0014] Preferably, the linkage component includes a sliding rail, two second sliding blocks, and a connecting pin. The connecting pin passes through the sliding rail and is detachably connected to the outer wall of the T-shaped fixed mounting plate.

[0015] Preferably, the heat dissipation component includes a mounting bracket and a cooling fan. The mounting bracket is detachably connected to both sides of the cutting blade bracket, and the outer walls of the mounting brackets on both sides are detachably connected to the cooling fan. The mounting bracket is provided with an air inlet slot. One cooling fan blows air in the direction of airflow, blowing external cold air toward the blade, while the other cooling fan draws air in the direction of airflow, expelling the hot air around the blade to the outside, thereby forming a directional cooling airflow.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, a second servo motor drives a transmission rod to rotate. The transmission of the first and second meshing gears enables the two transmission rods to rotate in opposite directions. The cam pushes the sliding mounting plate to drive the double blades to extend and retract alternately, reducing the continuous contact time between a single blade and the roll material, lowering the blade temperature to avoid local melting of the material, and preventing the blade from adhering to molten material, thereby reducing defects such as burrs, rough edges, and weld beads during the cutting process. The linkage component, through the cooperation of the sliding rail and the second sliding block, drives the other sliding mounting plate to move up when one side of the sliding mounting plate moves down, ensuring the synchronicity and smoothness of the alternating action of the double blades and improving cutting efficiency.

[0018] 2. In this invention, the cooling fans on both sides of the cutting blade support form a directional cooling airflow, blowing in cold air on one side and drawing out hot air on the other, continuously cooling the alternating cutting blade and further avoiding cutting defects caused by frictional heat generation.

[0019] 3. In this invention, the lifting and lowering of the clamping plate is controlled independently by the second telescopic cylinder, simplifying the equipment structure and reducing interference between moving parts while ensuring the clamping effect of the rolled material during cutting. The two blades complete the cutting by directly alternating lifting and lowering through the drive assembly, without the need to move the blade holder as a whole. At the same time, the cooling advantage of alternating cutting by the two blades is maintained, avoiding the generation of cutting defects and improving the stability and practicality of the equipment operation.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments. The present invention provides the following embodiments.

[0025] Example 1, such as Figure 1 as well as Figure 2The diagram shows a preferred embodiment of a slitting device for bag processing materials according to the present invention. The slitting device for bag processing materials in this embodiment includes a cutting bracket 100. A roll material bracket 101 is detachably connected to one side of the upper end of the cutting bracket 100. The roll material bracket 101 is used to fix the blister roll material. A cutting blade bracket 103 is detachably connected to the other end of the cutting bracket 100. A first telescopic cylinder 201 is detachably connected to the top inner side of the cutting blade bracket 103. The telescopic end of the first telescopic cylinder 201 is detachably connected to... There is a cutting blade holder 200, and the two sides of the cutting support 100 are detachably connected to the first support 107. The two sides of the first support 107 are rotatably connected to the flattening roller 102. The cutting support 100 is equipped with a conveying assembly, which conveys the blister roll material towards the cutting blade support 103. In this embodiment, the blister roll material is conveyed along the upper end of the cutting support 100 towards the cutting blade support 103. The first telescopic cylinder 201 extends, causing the cutting blade holder 200 to move downward to cut the roll material into a suitable length for subsequent blister forming.

[0026] Specific conveying components can be adopted as follows: Figure 3 In the embodiment shown, the conveying assembly includes a conveying roller 104, a first servo motor 105, a bottom support roller 106, and two second supports 108. The two second supports 108 are detachably connected to both sides of the cutting bracket 100. The conveying roller 104 and the bottom support roller 106 are rotatably connected between the two second supports 108. The cutting bracket 100 is provided with a through groove at the position of the conveying roller 104 and the bottom support roller 106. The outer wall of one side of the second support 108 is detachably connected to the first servo motor 105. The rotating end of the first servo motor 105 is fixedly connected to one end of the conveying roller 104. In this embodiment, the first servo motor 105 rotates to drive the conveying roller 104 to rotate. The conveying roller 104 and the bottom support roller 106 clamp the blister roll material and convey it towards the direction of the cutting blade bracket 103, thereby enabling the roll material to be cut in conjunction with the falling of the cutting blade holder 200.

[0027] To ensure a smooth cut surface during cutting, the specific structure can be as follows: Figure 4In the embodiment shown, clamping assemblies 300 are installed on both sides of the cutting blade holder 200. Each clamping assembly 300 includes an assembly plate 301, a clamping plate 302, a sliding plate 303, a return spring 304, and a limiting plate 305. The assembly plates 301 are fixedly connected to the outer walls of both sides of the cutting blade holder 200. The sliding plate 303 is slidably connected to the assembly plate 301. The clamping plate 302 is fixedly connected to the bottom of the sliding plate 303. The limiting plate 305 is detachably connected to the upper end of the sliding plate 303. The return spring 304 is sleeved on the limiting plate 305. The outer wall of the sliding plate 303 between the assembly plate 301 and the sliding plate 303 has one end of the return spring 304 fixedly connected to the limiting plate 305, and the other end of the return spring 304 fixedly connected to the upper end of the assembly plate 301. In this embodiment, when the cutting blade holder 200 moves downward, the two side pressing plates 302 first contact the blister roll material, and as the cutting blade holder 200 moves downward, the sliding plate 303 moves upward and stretches the return spring 304. The assembly applies a pressing force to the blister roll material, thereby preventing the blister roll material from moving during cutting and ensuring the flatness of the cut.

[0028] To prevent the continuous friction between the blade and the sheet material during cutting of thermoformed sheets, which generates heat and causes localized melting at the cut edge, with the molten material adhering to the blade surface and leading to defects such as stringing, burrs, and weld beads in subsequent cuts, a specific structural design can be adopted as follows: Figure 5 In the embodiment shown, a T-shaped mounting plate 204 is fixedly connected to the inner bottom of the cutting blade holder 200. Sliding mounting plates 205 are slidably connected to the outer walls of both sides of the T-shaped mounting plate 204. A second cutting blade 203 is detachably connected to the outer wall of one sliding mounting plate 205, and a first cutting blade 202 is detachably connected to the outer wall of the other sliding mounting plate 205. When the first cutting blade 202 rises, the second cutting blade 203 falls; when the second cutting blade 203 rises, the first cutting blade 202 falls. The first cutting blade 202 and the second cutting blade 203... The cutting blades 203 alternately rise and fall, with the blade edges of the first cutting blade 202 and the second cutting blade 203 fitting together. In this embodiment, when cutting the sheet metal, the first cutting blade 202 extends to cooperate with the descent of the first telescopic cylinder 201 to cut the sheet metal. After cutting, the first cutting blade 202 retracts, causing the second cutting blade 203 to extend for the next cut. This alternating extension and cutting is repeated, which can reduce the temperature of the first cutting blade 202 and the second cutting blade 203 and avoid defects such as wire drawing, burrs, and weld beads during cutting.

[0029] In order to achieve the alternating extension and retraction of the first cutting blade 202 and the second cutting blade 203, the specific structure of the drive component can be as follows: Figure 6 , Figure 7 as well as Figure 8In the embodiment shown, the upper ends of the sliding mounting plates 205 on both sides extend outward. The two ends of the T-shaped fixed mounting plate 204 are detachably connected to mounting brackets 213. Transmission rods 207 are rotatably connected to the left and right sides between the two mounting brackets 213. Multiple cams 208 are fixedly connected to the outer walls of the transmission rods 207 on both sides. A second servo motor 206 is detachably connected to the outer wall of one mounting bracket 213. The rotating end of the second servo motor 206 is fixedly connected to one end of one transmission rod 207. The end of the transmission rods 207 away from the second servo motor 206 extends through the other mounting bracket 213 and is detachably connected to a first meshing gear 209. Two meshing second meshing gears 210 are rotatably connected to the outer wall of the other mounting bracket 213 located between the first meshing gears 209 on both sides. The first meshing gear 209 meshes with the adjacent second meshing gear 210. The second servo motor 206 has a built-in rotary encoder. The convex portion of the multiple cams 208 on each transmission rod 207... The two transmission rods 207 rotate in opposite directions. When one cam 208 pushes the corresponding sliding mounting plate 205 downward, the other cam 208 moves away from the corresponding sliding mounting plate 205, realizing the alternating extension and retraction of the first cutting blade 202 and the second cutting blade 203. In this embodiment, the second servo motor 206 rotates to drive one transmission rod 207 and the first meshing gear 209 to rotate. Through the setting of the second meshing gears 210 on both sides, the first meshing gear 209 on the other side rotates in the opposite direction to the first meshing gear 209 on one side. Thus, the rotation causes the protruding end of the cam 208 to contact the lateral extension of the T-shaped fixed mounting plate 204, causing it to move downward. This achieves the purpose of alternating extension of the first cutting blade 202 and the second cutting blade 203. The rotation angle of the second servo motor 206 is precisely controlled by the rotary encoder, so that the extension of the first cutting blade 202 or the second cutting blade 203 can be precisely controlled.

[0030] When the first cutting blade 202 or the second cutting blade 203 extends, the other side needs to move upward to achieve alternating extension and rising. The specific structure can be as follows: Figure 10As shown in embodiment 11, the outer walls of both sides of the T-shaped fixed mounting plate 204 are rotatably connected to a linkage assembly 400. The linkage assembly 400 includes a sliding rail 401, two second sliding blocks 402, and a connecting pin 403. The connecting pin 403 passes through the sliding rail 401 and is detachably connected to the outer wall of the T-shaped fixed mounting plate 204. The sliding rail 401 rotates along the outer wall of the connecting pin 403. The two second sliding blocks 402 are slidably connected to the inner sides of the sliding rail 401. The two second sliding blocks 402 are rotatably connected to the outer walls of the two sliding mounting plates 205 respectively. In this embodiment, when one side of the sliding mounting plate 205 moves downward, the second sliding block 402 and one side of the sliding mounting plate 205 rotate adaptively and slide adaptively inside the sliding rail 401, thereby enabling the sliding rail 401 to rotate along the connecting pin 403, thereby enabling the other side of the sliding mounting plate 205 to move upward, thereby enabling the other side of the sliding mounting plate 205 to move upward when one side of the sliding mounting plate 205 moves downward.

[0031] The specific structure for the sliding mounting plate 205 and the T-shaped fixed mounting plate 204 to slide can be as follows: Figure 9 In the embodiment shown, the outer walls of both sides of the T-shaped fixed mounting plate 204 are provided with sliding grooves 212, and the opposite surfaces of the two sliding mounting plates 205 are fixedly connected with first sliding blocks 211. The first sliding blocks 211 are slidably connected to the inside of the sliding grooves 212. In this embodiment, by sliding the first sliding blocks 211 inside the sliding grooves 212, the alternating lifting and lowering of the two sliding mounting plates 205 can be realized.

[0032] Because the blades of the first cutting blade 202 and the second cutting blade 203 are in close contact with each other, they are prone to generating heat through friction during alternating lifting and lowering. To dissipate heat from the first cutting blade 202 and the second cutting blade 203, a specific structure can be adopted as follows: Figure 12 In the embodiment shown, mounting brackets 501 are detachably connected to both sides of the cutting blade bracket 103. Cooling fans 500 are detachably connected to the outer walls of the mounting brackets 501 on both sides. Air inlet slots are provided on the mounting brackets 501. One cooling fan 500 blows external cold air toward the blade, while the other cooling fan 500 draws in hot air around the blade to exhaust it outward, thereby forming a directional cooling airflow. In this embodiment, external air is blown toward the first cutting blade 202 and the second cutting blade 203 by one cooling fan 500 to cool them down. The other cooling fan 500 can help exhaust the heat from the first cutting blade 202 and the second cutting blade 203 to the outside, thereby preventing the first cutting blade 202 and the second cutting blade 203 from generating heat through friction during the lifting and lowering process.

[0033] Example 2, as Figure 13As shown, this is another preferred embodiment of the present invention. The difference between the bag processing material cutting equipment in this embodiment and that in embodiment 1 is that the first telescopic cylinder 201 is omitted, the cutting blade holder 200 is detachably connected to the inside of the cutting blade support 103, and the pressing assembly 300 includes two pressing plates 302, a sliding plate 303, and a second telescopic cylinder 306. The two second telescopic cylinders 306 are detachably connected to the outer walls of both sides of the cutting blade support 103, and the sliding plates 303 on both sides are detachably connected to the telescopic ends of the two second telescopic cylinders 306 respectively. The pressing plates 302 on both sides are fixedly connected to the bottom of the sliding plates 303 respectively. In this embodiment, during cutting, the first cutting blade 202 and the second cutting blade 203 are alternately raised and lowered by the drive assembly. When lowering, the blister roll is cut. The extension of the second telescopic cylinder 306 causes the pressing plate 302 to press the blister roll, thereby eliminating the lifting stroke of the cutting blade holder 200 and still avoiding the temperature rise of the first cutting blade 202 or the second cutting blade 203.

[0034] Example 3 differs from Example 1 in that the rotational speed of the second servo motor 206 is increased to a preset value. When the cutting blade holder 200 descends to cut the blister roll, the second cutting blade 203 and the first cutting blade 202 rapidly rise and fall to cut the blister roll, realizing a composite cutting method of impact and shearing, which can avoid the appearance of slant, bottom indentation and burrs on the cross-section.

[0035] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted herein.
