Description

Technical Field

[0001] This utility model belongs to the field of tire manufacturing technology, and specifically relates to a cord layer cutting mechanism to prevent material blockage. Background Technology

[0002] Currently, the cord cutting mechanism on tire forming machines typically involves installing a cutting board on a conveyor belt. When the cord is conveyed to the cutting board, it rises above the cutting board, and then the cutting blade descends and inserts into the cord on the cutting board, moving left and right to cut the cord.

[0003] Over time, the cutting board can deform, causing the gap between the cutting board and the conveyor belt to widen. During the conveying process, this gap can occur, leading to material blockage and preventing the fabric from being conveyed properly. This necessitates manual shutdown for repair, wasting materials and reducing production efficiency.

[0004] Therefore, this application provides a fabric layer cutting mechanism to prevent material blockage, thereby avoiding fabric blockage by improving the conveyor belt structure. Utility Model Content

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments of this application and the accompanying drawings.

[0039] like Figure 1 and Figure 7-8 As shown, a fabric layer cutting mechanism to prevent material blockage includes: a pre-cutting conveyor belt 1 and a post-cutting conveyor belt 2 arranged at intervals, and a cutting device 3 is provided between the pre-cutting conveyor belt 1 and the post-cutting conveyor belt 2.

[0040] The cutting device 3 includes a cutting component, an angle adjustment component, and a knife and anvil assembly. The knife and anvil assembly is installed below the junction of the pre-cutting conveyor belt 1 and the post-cutting conveyor belt 2. The angle adjustment component is installed above the conveyor belt, and the cutting component is installed below the angle adjustment component. The angle adjustment component is used to adjust the angle of the cutting component.

[0041] A telescopic component 4 is provided on the side of the pre-cutting conveyor belt 1 adjacent to the post-cutting conveyor belt 2. The telescopic component 4 is used to drive the conveyor belt 101 on the pre-cutting conveyor belt 1 to approach or move away from the post-cutting conveyor belt 2.

[0042] By setting the telescopic component 4, the cutting board assembly can be positioned below the conveyor belt 101. When the curtain fabric 5 needs to be cut, the telescopic component 4 retracts the conveyor belt 101 above the cutting board assembly, allowing the cutting board assembly and the cutting blade assembly to work together to cut the curtain fabric 5. This avoids the material blockage problem caused by the gap between the cutting board and the conveyor belt in traditional curtain fabric cutting mechanisms, thus improving production efficiency and reducing the waste of the curtain fabric 5.

[0043] like Figure 7-8 As shown, the pre-cutting conveyor belt 1 includes a fixed side plate on each side, and several conveying rollers are installed between the fixed side plates.

[0044] The telescopic assembly 4 includes: a telescopic plate 402 on the left and right, the telescopic plate 402 and the corresponding fixed side plate are slidably connected by a linear slide rail, a conveyor belt telescopic cylinder 401 on the left and right and mounted on the fixed side plate, the cylinder rod of the conveyor belt telescopic cylinder 401 is hinged to the corresponding telescopic plate 402, a telescopic roller 403 is installed between the two telescopic plates 402 and at the front and rear, and the conveyor belt 101 is wound around the conveyor roller and the telescopic roller 403;

[0045] When the conveyor belt telescopic cylinder 401 drives the telescopic plate 402 to extend and retract, the two telescopic rollers 403 extend and retract synchronously, the position of the telescopic rollers 403 changes, and the length of the conveyor belt 101 remains unchanged.

[0046] like Figure 2-5 As shown, the knife and anvil assembly includes: a knife and anvil bracket 309, a knife and anvil lifting cylinder 310, and a knife and anvil 311. The knife and anvil bracket 309 is fixedly installed below the junction of the pre-cutting conveyor belt 1 and the post-cutting conveyor belt 2.

Each side of the cutting frame 304 is equipped with a pressing cylinder 312, and the cylinder rod of the pressing cylinder 312 is equipped with a pressing plate 307. The cutting knife assembly cooperates with the cutting anvil 311 to cut the curtain fabric 5.

[0048] like Figure 6As shown, the cutting blade assembly includes: a cutting blade mounting bracket 324 mounted on the second linear slide rail 323, a timing belt clamp 322 mounted below the cutting blade mounting bracket 324 and connected to the timing belt 305, and a cutting blade lifting cylinder 319 mounted on the cutting blade mounting bracket 324. A floating cutting blade holder 320 is mounted on the cylinder rod of the cutting blade lifting cylinder 319. The floating cutting blade holder 320 is used to avoid the cord during cutting and prevent the cord from being cut.

[0049] The floating cutter holder 320 includes a third linear slide rail 326, a cutter mounting block 327, a cutter 308, and a cutter guide groove 325. A cutter guide wheel 321 is provided on the cutter mounting frame 324. The cutter mounting block 327 is disposed on the third linear slide rail 326 of the floating cutter holder 320 and is fixed by a locking component. In one specific embodiment, the locking component can be a pin or a set bolt. The cutter 308 is mounted on the cutter mounting block 327. The cutter guide groove 325 cooperates with the cutter guide wheel 321 to prevent the cutter 308 from deviating when it rises or falls.

[0050] like Figure 2-4 As shown, the angle adjustment assembly includes: mounting plate 301, rotary bearing 313, limit cylinder 302, top block 303, handwheel 318, lead screw 314, nut 315, rack 317 and first linear slide rail 316;

[0051] The slewing bearing 313 is mounted on the mounting plate 301, and the cutting assembly is mounted on the slewing bearing 313 to enable the cutting assembly and the mounting plate 301 to rotate relative to each other. The limiting cylinder 302 is mounted on the mounting plate 301, and the top block 303 is mounted on the extended end of the limiting cylinder 302. The top block 303 cooperates with the limiting cylinder 302 to limit the slewing bearing 313.

[0052] The rack 317 and the first linear slide rail 316 are mounted on the side of the mounting plate 301. The rack 317 is slidably connected to the side of the mounting plate 301 through the first linear slide rail 316. The outer circumference of the rotary bearing 313 is a gear. By moving the rack 317, the rotary bearing 313 is driven to rotate.

[0053] One end of the rack 317 is fixedly connected to the nut 315. The nut 315 is threadedly connected to the lead screw 314. The lead screw 314 is rotatably mounted on the mounting plate 301. A handwheel 318 is installed at one end of the lead screw 314. By rotating the handwheel 318, the lead screw 314 drives the nut 315 to move, thereby controlling the movement of the rack 317, driving the rotary bearing 313 to rotate, and adjusting the angle of the cutting assembly.

[0054] In one specific embodiment, the cutting board 311 has a cutting groove for the cutting knife 308 to cut into the fabric 5.

[0055] Working principle: When conveying the fabric 5, the cutting anvil 311 is below the conveyor belt 101. The conveyor belt telescopic cylinder 401 extends, driving the telescopic plate 402 to extend. The pre-cutting conveyor belt 1 and the post-cutting conveyor belt 2 are engaged. The pressing cylinder 312 and the cutting blade lifting cylinder 319 are both in the retracted state, and the cutting blade assembly is directly above the cutting anvil 311. When the fabric 5 is conveyed to the predetermined length, the conveyor belt telescopic cylinder 401 retracts, driving the telescopic plate 402 to retract, creating a certain gap between the pre-cutting conveyor belt 1 and the post-cutting conveyor belt 2. At this time, to prevent the fabric 5 from retracting and stretching, the pre-cutting conveyor belt 1 needs to be conveyed forward synchronously, with the conveying distance being the distance that the conveyor belt telescopic cylinder 401 retracts. After leaving a gap between the two sets of conveyor belts, the cutting anvil lifting cylinder 310 extends, causing the cutting anvil 311 to rise from the gap in the conveyor belt to above the conveyor belt, lifting the fabric 5. The pressing cylinder 312 descends, and the pressing plate 307 presses the curtain fabric 5 onto the cutting anvil 311. Then, the cutting blade lifting cylinder 319 descends, driving the cutting blade 308 into the cutting groove on the cutting anvil 311 to pierce the curtain fabric 5. Then, the motor 306 drives the synchronous belt 305 to move the cutting blade 308 left and right to cut the curtain fabric 5. After cutting, the cutting blade lifting cylinder 319 and the pressing cylinder 312 rise, the cutting anvil lifting cylinder 310 descends, and the cutting blade 308, the pressing plate 307, and the cutting anvil 311 all return to their initial positions. The conveyor belt telescopic cylinder 401 extends, driving the telescopic plate 402 to extend. The pre-cutting conveyor belt 1 and the post-cutting conveyor belt 2 reconnect, and the curtain fabric 5 continues to be conveyed to a fixed length.

[0056] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
