Description

Technical Field

[0001] This utility model relates to the field of industrial belt production technology, and more specifically, to a fixed-length cutting system for adhesive belts. Background Technology

[0002] Industrial belts are products primarily made of rubber. Their production involves a series of processes including calendering, vulcanization, and molding. The molds used in the vulcanization stage can only accommodate belts with a width of 1070mm, while the calendering stage produces belts wider than 1200mm. This necessitates cutting the calendered belt to a fixed length, first cutting it into 1070mm lengths, and then splicing the 1200mm ends to form a continuous 1070mm wide belt. Currently, the cutting equipment used by the company has a low degree of automation, requiring 2-3 people to work together, resulting in high labor intensity, high labor costs, and low production efficiency. Therefore, the company needs to automate the cutting process, leading to this project. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fixed-length tape cutting system. This invention releases the tape roll through an unwinding device, the padding cloth is recycled by the padding cloth recycling device, the tape is output to the cutting device for fixed-length cutting, and the cut tape is dragged by a pneumatic gripper to the output conveyor belt for output. This invention has the advantage of high automation, and a series of processes such as unwinding, cutting, and output can be completed automatically.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A tape length-cutting system includes an unwinding device, a cutting device, and an output conveyor belt. The unwinding device includes a roll holder on which a roll of tape from a calendering process is rotatably mounted. A tape conveying mechanism and a pad collection mechanism are respectively installed on both sides of the roll holder. The cutting device includes a cutting worktable and an extension platform. A cutting blade mechanism is installed on the cutting worktable. The tape unwound from the roll holder is conveyed to the cutting worktable via the tape conveying mechanism. The extension platform is laterally connected to the cutting worktable. A first tape dragging mechanism is installed on the extension platform. The first tape dragging mechanism drags the tape past the cutting blade mechanism and determines the tape cutting length. The output conveyor belt is installed on the side of the extension platform. A second tape dragging mechanism is installed on the output conveyor belt. The second tape dragging mechanism drags the cut tape onto the output conveyor belt for output.

[0006] Furthermore, the conveyor belt mechanism includes a first drive roller and a conveyor belt roller that are rotatably mounted. The conveyor belt roller is mounted on the side of the cutting table and a motor is connected to it. The conveyor belt travels along the first drive roller toward the conveyor belt roller. A pressure roller is installed between the first drive roller and the conveyor belt roller.

[0007] Furthermore, the pad fabric recycling mechanism includes a second drive roller and a take-up roller that are rotatably mounted, with the pad fabric traveling along the second drive roller toward the take-up roller.

[0008] Furthermore, the cutting device is installed near the junction of the cutting worktable and the extension platform. The cutting device includes a cutter bracket and an electric trolley. The cutter bracket is a portal frame that straddles the cutting worktable. A track is laid on the inner side of the cutter bracket, and the electric trolley is mounted on the track. A cutter is fixedly connected to the bottom of the electric trolley.

[0009] Furthermore, a cutting table is provided with a cutting groove, which is opened to correspond to the cutting blade's movement trajectory line. The bottom end of the cutting blade extends and is inserted into the cutting groove, and the stroke of the cutting blade is greater than the width of the tape.

[0010] Furthermore, a pressure-pressing assembly is installed on each side of the cutter bracket, and the two pressure-pressing assemblies are installed symmetrically. The pressure-pressing assembly includes a push cylinder and a pressure rod. The push cylinder is installed vertically downward, and the pressure rod is connected to the piston rod end of the push cylinder.

[0011] Furthermore, the first rubber-dragging mechanism includes a suspended frame, a rail groove, a drag chain track, and a towing frame. The suspended frame is fixedly installed above the extension platform. The rail groove is installed on the suspended frame and is parallel to the extension platform surface. The drag chain track is installed on the suspended frame. The towing frame is guided through the rail groove and connected to the drag chain track. The towing frame is fixedly connected to a pneumatic gripper beam. A first pneumatic gripper assembly is installed on the side of the pneumatic gripper beam. The second rubber-dragging mechanism has the same structure as the first rubber-dragging mechanism. A second pneumatic gripper assembly is installed on the pneumatic gripper beam of the second rubber-dragging mechanism. The first and second pneumatic gripper assemblies are installed in the same direction.

[0012] Furthermore, the height of the cutting workbench is higher than that of the extension platform, and the first pneumatic gripper assembly approaches the docking position between the cutting workbench and the extension platform to receive the material.

[0013] Furthermore, the platform height of the extension platform is higher than the surface height of the discharge conveyor belt. A receiving extension plate is connected to the side of the extension platform near the discharge conveyor belt. Several slots are opened along the length direction of the receiving extension plate. The number of slots matches the number of pneumatic grippers in the second pneumatic gripper group. The width of the slots is greater than the finger width of the pneumatic grippers in the second pneumatic gripper group.

[0014] The beneficial effects of this utility model are:

[0015] This invention releases the tape roll via an unwinding device, the padding cloth is recovered by a padding cloth recycling device, and the tape is output to a cutting device for fixed-length cutting. The cut tape is then dragged by a pneumatic gripper to the output conveyor belt for output. This invention has the advantage of high automation, as a series of processes such as unwinding, cutting, and output can be completed automatically. After applying this invention, the amount of manual labor required is significantly reduced, and the labor intensity of workers is significantly improved. This invention also helps to improve the efficiency of cutting operations and stabilize the quality of work. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4The illustrated tape cutting system includes an unwinding device 1, a cutting device 2, and a discharge conveyor belt 3. The unwinding device 1 includes a tape holder 11 on which a tape roll from the calendering process is rotatably mounted. The tape roll includes a layer of tape and a pad, with one layer of pad and one layer of tape. The pad serves to protect the tape, preventing adhesion between tapes and preventing impurities from contaminating the tape. To recover the pad and output the tape, a tape conveying mechanism 12 and a pad recovery mechanism 13 are respectively installed on both sides of the tape holder 11. When the tape roll unwinds, the tape conveying mechanism 12 outputs the tape to the left, and the pad recovery mechanism 13 recovers the pad to the right. The cutting device 2 includes a cutting worktable 21 and an extension platform 22. The cutting worktable 21 is equipped with... Equipped with a cutting mechanism 23, the tape released from the film roll holder 11 (i.e., the tape roll) is conveyed to the cutting worktable 21 via the tape conveyor mechanism 12. An extension platform 22 is laterally connected to the cutting worktable 21. A first tape-dragging mechanism 4 is installed on the extension platform 22. The first tape-dragging mechanism 4 grabs and drags the tape past the cutting mechanism 23. The cutting length of the tape (i.e., the distance from the tape dragging head to the cutting mechanism 23, which our company requires to be set to 1070mm) is determined by the stroke of the first tape-dragging mechanism 4. A discharge conveyor belt 3 is installed on the side of the extension platform 22, and a second tape-dragging mechanism 5 is installed on the discharge conveyor belt 3. The cut tape becomes a piece of adhesive tape, which is then dragged onto the discharge conveyor belt 3 by the second tape-dragging mechanism 5 for output. Figure 4 As shown, the transmission direction of the discharge conveyor belt 3 is set at a 90-degree angle to the movement direction of the tape on the cutting table 21 and the extension platform 22. This way, the output tape is aligned with the long side (that is, the 1200mm side), which facilitates subsequent splicing into a new tape with a width of 1070mm. (After re-splicing, the width and length changes meet the requirements, and the tape fiber texture will also change to be different from that of the newly calendered tape, thus improving the strength of the new tape.)

[0023] like Figure 1 and Figure 3As shown, the tape conveying mechanism 12 includes a first drive roller 121 and a tape roller 122 rotatably mounted. The tape roller 122 is mounted on the side of the cutting table 21, and a motor 124 is connected to the tape roller 122. The tape roller 122 is the drive roller. When the tape roller 122 is turned on, the tape moves along the first drive roller 121 toward the tape roller 122, thus creating a tape feeding effect on the cutting table 21. A pressure roller 123 is installed between the first drive roller 121 and the tape roller 122, and the pressure roller 123 provides a pressing effect on the tape surface. To maintain a certain tension in the tape, the padding cloth recycling mechanism 13 includes a second drive roller 131 and a take-up roller 132 that are rotatably mounted. The take-up roller 132 also needs to be equipped with a motor 124 and is also an active roller. When the take-up roller 132 starts, the padding cloth moves along the second drive roller 131 toward the take-up roller 132. In fact, the tape can be automatically pulled out during the padding cloth pulling process. Therefore, the take-up roller 132 and the tape roller 122 need to rotate synchronously and at the same speed so that the padding cloth and tape can be separated and output separately.

[0024] like Figure 1 As shown, the cutting device 2 is installed near the joint between the cutting worktable 21 and the extension platform 22, as... Figure 2 As shown, the cutting device 2 includes a cutter support 231 and an electric trolley 233. The cutter support 231 is a portal frame, straddling the cutting worktable 21. A track 232 is laid inside the cutter support 231, and the electric trolley 233 is mounted on the track 232. A cutter 234 is fixedly connected to the bottom of the electric trolley 233. The movement of the electric trolley 233 drives the movement of the cutter 234. A cutting groove 211 is provided on the cutting worktable 211, corresponding to the movement trajectory of the cutter 234. The bottom end of the cutter 234 extends and inserts into the cutting groove 211. When the tape is laid on the cutting worktable 21, the cutter 234 moves past it and cuts the tape. In this invention, the stroke of the cutter 234 is greater than the width of the tape, so that the cutter 234 can avoid the tape in advance. Furthermore, the tape can only be completely cut during the cutting process. Before cutting the tape, the tape must be pressed tightly at both ends of the cutting position. Therefore, this utility model has a tape pressing component 24 installed on both sides of the cutter bracket 231. The two tape pressing components 24 are installed symmetrically. The tape pressing component 24 includes a push cylinder 241 and a pressure rod 242. The push cylinder 241 is fixed to the side of the cutter bracket 231 by a frame plate and is installed vertically downward. The pressure rod 242 is connected to the piston rod end of the push cylinder 241. When the piston rod end of the push cylinder 241 extends outward, it can drive the pressure rod 242 downward. The downward movement of the pressure rod 242 can press tightly on the tape surface. The two tape pressing components 24 are started at the same time, which can form a pressing effect on both sides of the tape cutting position. The electric trolley 233 starts after the tape is dragged into place (the tape length reaches the requirement), and the cutter 234 moves to complete the cutting of the tape.

[0025] like Figure 1 As shown, the first dragging mechanism 4 includes a suspended frame 41, a rail groove 42, a drag chain track 43, and a dragging frame 44. The suspended frame 41 is fixedly installed above the extension platform 22 via a column. The rail groove 42 is installed on the suspended frame 41 and is parallel to the surface of the extension platform 22. The drag chain track 43 is installed on the suspended frame 41. The dragging frame 44 is guided and inserted through the rail groove 42. The length direction of the rail groove 42 is the direction of movement of the dragging frame 44. The drag chain track 43 is connected to the dragging frame 44. The movement of the dragging frame 44 is achieved by the movement of the drag chain track 43. The drag chain track 43 is existing technology and is mostly used for dragging components that need to move (commonly used in various machine tools). The specific structure will not be described in detail here. The bottom of the dragging frame 44 is fixedly connected to... A pneumatic gripper beam 45 is connected to the first pneumatic gripper assembly 46, which is mounted on the side of the pneumatic gripper beam 45. The movement of the towing frame 44 can cause the first pneumatic gripper assembly 46 to move. The second adhesive dragging mechanism 5 has the same structure as the first adhesive dragging mechanism 4, but the installation position of the second adhesive dragging mechanism 5 is different. The second adhesive dragging mechanism 5 is straddled above the discharge conveyor belt 3. The second pneumatic gripper assembly 51 is mounted on the pneumatic gripper beam 45 of the second adhesive dragging mechanism 5. The first pneumatic gripper assembly 46 and the second pneumatic gripper assembly 51 are installed in the same direction. The first pneumatic gripper assembly 46 and the second pneumatic gripper assembly 51 do not interfere with each other during the movement. Both the first pneumatic gripper assembly 46 and the second pneumatic gripper assembly 51 use finger cylinders. The cylinder finger cylinders can be used to grip the end of the tape.

[0026] like Figure 2 As shown, the height of the cutting table 21 is higher than that of the extension platform 22. The first pneumatic gripper assembly 46 approaches the docking position between the cutting table 21 and the extension platform 22 to receive the material. The first pneumatic gripper assembly 46 has two strokes. The first stroke is the dragging stroke, which allows the tape to be dragged out at a fixed length (the distance between the dragging end point and the cutter 234 is set to 1070mm). The second stroke is the release stroke. After the tape is pressed by the adhesive pressing components 24 on both sides of the cutter 234, the cylinder grippers of the first pneumatic gripper assembly 46 release, and the first pneumatic gripper assembly 46 separates from the tape. After the tape is cut, the resulting adhesive tape requires the second pneumatic gripper. Group 51 relays the gripping output. At this time, the first pneumatic gripper group 46 needs to return to receive the material. The height of the cutting table 21 is higher than that of the extension platform 22 to facilitate the receiving of the material by the first pneumatic gripper group 46. Since the tape head that has just been cut is still on the cutting table 21, the tape roller 122 needs to be started first to make the tape move a certain distance towards the extension platform 22. At this time, the cylinder grippers of the first pneumatic gripper group 46 are in the released state. Since the first pneumatic gripper group 46 is close to the cutting table 21, the moving tape head can just enter the cylinder grippers of the first pneumatic gripper group 46 so that it can be gripped smoothly.

[0027] like Figure 1As shown, the platform height of the extension platform 22 is higher than the belt height of the discharge conveyor belt 3. This is to facilitate the relay gripping of the material by the second pneumatic gripper assembly 51. Since the extension platform 22 is not suitable for setting up a conveyor belt travel structure, an alternative gripping method is adopted. In this invention, a receiving extension plate 221 is connected to the side of the extension platform 22 near the discharge conveyor belt 3. Several slots 222 are opened along the length of the receiving extension plate 221. The number of slots 222 is the same as the number of pneumatic grippers in the second pneumatic gripper assembly 51. The width of the slot 222 is greater than the width of the gripper fingers in the second gripper group 51. After the first gripper group 46 releases the tape, the tape is laid flat on the extension platform 22, and the tape head is exactly on the receiving extension plate 221. Due to the presence of the slot 222, the gripping position of the tape head is exposed, which leaves gripping space for the cylinder fingers in the second gripper group 51, making it convenient for the second gripper group 51 to grip. After the second gripper group 51 grips the tape, it moves directly to drag the tape onto the discharge conveyor belt 3.

[0028] This invention has the advantage of a high degree of automation. A series of processes such as unwinding, cutting, and output can be completed automatically. After applying this invention, only a single worker needs to perform observation and coordination tasks. Compared with the traditional multi-person operation method, this invention significantly reduces the amount of manual labor and significantly improves the labor intensity of workers. Automated operation also improves the efficiency of cutting operations and the quality of cutting operations is relatively stable.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
