An ultra-low elongation maintenance-free V-belt production device

Abstract

The present invention discloses a production device for an ultra-low elongation maintenance-free V-belt, including a working plate and a covering cloth mechanism. The covering cloth mechanism includes a cloth rotating assembly and a second motor. The output end of the second motor is fixedly connected with a second gear, and a first gear is meshed with the top of the second gear. The cloth rotating assembly includes a rotating ring. In the present invention, the second motor drives the second gear to rotate, the second gear drives the first gear to rotate, and the first gear drives the rotating ring to rotate, so as to realize the winding of the base glue at the middle position of the rotating ring. When the rotating ring rotates to the position where the lifting assembly is at the bottom end of the rotating ring, when the lifting block moves upward, the spring is compressed. When the distance between the base glue and the covering cloth outlet becomes shorter, the radius of the covering cloth outlet becomes shorter, and the linear velocity of the covering cloth outlet becomes smaller, so that the covering cloth outlet speed is reduced, the covering cloth is wound more tightly around the lower half circle of the V-belt, avoiding the generation of voids in the covering cloth, and the base glue will not be deformed due to large tension during the winding of the upper half circle of the V-belt.

Description

Technical Field

[0001] The present invention relates to the technical field of V-belt covering processes, and specifically to a production device for V-belts with ultra-low elongation and maintenance-free properties. Background Art

[0002] A V-belt is a conveyor belt for mechanical equipment, also known as a V-shaped belt. V-belts are divided into two types: special core structures and rope core structures, each consisting of four parts: covering cloth, top rubber, tensile body, and bottom rubber. The production process of V-belts is as follows: The mixed rubber is hot-refined into a base, the rope core such as rope yarn is impregnated with slurry, and then the bottom rubber is fixed on the rope core. The bottom rubber of the V-belt does not have high-strength mechanical properties. Finally, the coiled covering cloth slurry is wound around the outside of the bottom rubber to enhance the tensile performance of the V-belt. After shaping, a preliminary product of the V-belt is formed. After a series of fine processing such as vulcanization, a formed V-belt can be obtained.

[0003] In the prior art, such as the "Automatic Cutting Device for Producing V-belts of a Pumping Unit" in Chinese Patent CN114131676B, it includes a placement mechanism and a positioning mechanism. The placement mechanism is slidably installed on a fixed frame, and a power component is provided on the fixed frame. The placement mechanism is used to sleeved the V-belt to be cut and is driven by the power component; a flap mechanism is installed on the placement mechanism, and the flap mechanism can reserve enough space for sleeving the V-belt. A cutting mechanism is slidably installed on the flap mechanism. The cutting mechanism includes a cam component and a cutting knife. The cam component enables the cutting knife to intermittently cut the V-belt; the positioning component can drive the closing claw component to open and close by using the moving component to position the V-belt, and drive the moving component to change the opening and closing angle of the closing claw component by using the transmission component to adapt to V-belts of different widths; this device can prevent unqualified cutting caused by the deviation of the V-belt position during cutting.

[0004] However, in the prior art, the cross-section of the V-belt is a V-shaped structure. During the process of covering the cloth with slurry, the amount of cloth wound around the lower half of the V-belt is less, and the amount of cloth wound around the upper half is more. In the traditional covering cloth mechanism, the cloth output speed is the same, resulting in too fast a cloth output speed for the lower half of the V-belt during winding, causing the cloth not to fit tightly with the bottom rubber, resulting in gaps in the middle of the covering cloth, and too slow a cloth output speed for the upper half of the V-belt, causing too much tension between the cloth and the bottom rubber, resulting in the cloth pulling and deforming the bottom rubber, affecting the quality of the finished V-belt. Summary of the Invention

[0005] (1) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the present invention provides a production device for V-belts with ultra-low elongation and maintenance-free properties, which solves the problems raised in the above background art.

[0008] The purpose of the present invention is to provide an ultra-low elongation maintenance-free V-belt production device to solve the problem that the cross-section of the V-belt proposed in the above background technology is a V-shaped structure. In the process of slurry wrapping, the lower half of the V-belt is wound with less cloth, and the upper half is wound with more cloth. In the traditional cloth wrapping mechanism, the cloth delivery speed of the wrapped cloth is consistent, resulting in that when the cloth is wrapped, the cloth delivery speed of the lower half of the V-belt is too fast, resulting in the cloth and the base glue cannot fit tightly, resulting in a gap in the middle of the wrapped cloth, and the cloth delivery speed of the upper half of the V-belt is too slow, resulting in excessive tension between the cloth and the base glue, causing the cloth to pull the base glue to deform, affecting the quality of the finished V-belt.

[0018] Beneficial Effects

[0020] 1. The ultra-low elongation maintenance-free V-belt production device drives the second gear to rotate through the second motor, and the second gear drives the first gear to rotate, so that the first gear drives the rotating ring to rotate, so as to realize the winding of the bottom rubber at the middle position of the rotating ring.

[0021] 2. The production device for the ultra-low elongation maintenance-free V-belt rotates the threaded hole to drive the pressing plate to move up and down, changing the height position of the pressing plate. When the arc block is pressed by the pressing plate, the distance by which the pressing plate presses the arc block upward changes, changing the distance between the second cloth guiding roller and the center of the rotating ring, and changing the unwinding speed of the covering cloth on the second cloth guiding roller, thereby achieving the effect of winding the covering cloth of V-belts with different specifications.

[0022] 3. For the production device of the ultra-low elongation maintenance-free V-belt, one end of the covering cloth is wound around the first cloth guiding roller, and the covering cloth rotates along the first cloth guiding roller with the rotating ring and winds between the covering cloth take-up roller and the base rubber at the position of the second cloth guiding roller. The covering cloth take-up roller itself is not driven by a motor, and the unwinding of the covering cloth take-up roller is realized by the tension of the covering cloth itself when the rotating ring rotates, so that the covering cloth take-up roller maintains a certain tension during the winding process, further reducing the gap when the covering cloth is wound around the base rubber.

[0040] The embodiment of the present invention provides an ultra-low elongation maintenance-free V-belt production device, such as Figure 1-8 As shown, it includes a working plate 1 and a cloth wrapping mechanism 3, the cloth wrapping mechanism 3 includes a cloth rotating assembly 31 and a second motor 33, the output end of the second motor 33 is fixedly connected to a second gear 37, the top end of the second gear 37 is meshed with a first gear 32, the cloth rotating assembly 31 includes a rotating ring 311, the rotating ring 311 is fixedly connected to the first gear 32, the side of the rotating ring 311 is fixedly connected to a first stabilizing rod 313, and the first stabilizing rod 313 is fixedly connected to the first gear 32. The outer wall of the rotating ring 311 is rotatably connected to the first cloth guide roller 312, and a movable groove 314 is provided at the bottom end of the rotating ring 311. The first gear 32 is fixedly connected to the circular guide rail 321 on the side away from the cloth transfer assembly 31. A through hole 323 is provided at the center position of the side of the first gear 32. The inner wall of the circular guide rail 321 is slidably connected to the limiting column 322. The base rubber of the V-belt is laid on the rope core, and the shaped base rubber is rolled up. When the wrapping cloth is wrapped around the outer layer of the base rubber of the V-belt, the rolled base rubber is passed through the center of the rotating ring 311 and rolled up on the other side of the rotating ring 311, so that the rotating ring 311 is rotated, so that the wrapping cloth on the first cloth guide roller 312 wraps the base rubber;

[0041] A support frame 35 is fixedly connected to the top end of the working plate 1. At the positions of the two limiting columns 322 on the top surface of the support frame 35, connecting columns 351 are fixedly connected. The connecting columns 351 are fixedly connected to the limiting columns 322. An extrusion assembly 36 is arranged on the top surface of the support frame 35. A lifting assembly 34 is arranged inside the movable groove 314. The lifting assembly 34 includes a lifting block 341. Connecting plates 342 are fixedly connected to the outer side walls at both ends of the lifting block 341. Lifting columns 343 are fixedly connected to the top surfaces of the connecting plates 342. Movable holes 315 are formed in the side wall of the rotating ring 311 at the positions of the lifting columns 343. The outer side wall of the lifting column 343 is slidably connected to the movable holes 315. Springs 344 are fixedly connected between the top surfaces of the two connecting plates 342 and the inner top wall of the movable groove 314. A second stabilizing rod 346 is fixedly connected to the side wall of the lifting block 341. A second fabric guiding roller 345 is rotatably connected to the outer side wall of the second stabilizing rod 346. A fixed column 347 is fixedly connected to the bottom end of the lifting block 341. The top end of the fixed column 347 penetrates through the bottom wall of the rotating ring 311 and is fixedly connected to an arc block 348. When the second motor 33 is started, the second motor 33 drives the second gear 37 to rotate. The second gear 37 drives the first gear 32 to rotate, so that the first gear 32 drives the rotating ring 311 to rotate. A plurality of first fabric guiding rollers 312 are fixedly connected to the side surface of the rotating ring 311. The rotation of the rotating ring 311 drives the first fabric guiding rollers 312 to rotate. The plurality of first fabric guiding rollers 312 and the second fabric guiding roller 345 are connected by a wrapped fabric. The wrapped fabric is wound on the fabric discharging mechanism 4. When a first fabric guiding roller 312 rotates one week, the bottom glue at the position of the second fabric guiding roller 345 is wound towards the middle position of the rotating ring 311. When the rotating ring 311 rotates to the position where the lifting assembly 34 is at the bottom end of the rotating ring 311, extrusion is generated between the arc block 348 and the extrusion plate 361, so that the arc block 348 moves towards the center of the rotating ring 311, and the arc block 348 drives the fixed column 347 to move upward. The fixed column 347 drives the lifting block 341 to move upward. When the lifting block 341 moves upward, the spring 344 is compressed. The second fabric guiding roller 345 on the lifting block 341 is closer to the bottom glue at the center of the rotating ring 311. Since the angular velocity of the rotation of the rotating ring 311 remains unchanged, when the distance between the bottom glue and the fabric outlet becomes shorter, the radius of the fabric discharging of the wrapped fabric becomes shorter, and the linear velocity of the fabric discharging of the wrapped fabric becomes smaller, so that the fabric discharging speed of the wrapped fabric decreases. When the rotating ring 311 rotates to the position where the lifting assembly 34 is at the top end of the rotating ring 311, the spring 344 is no longer compressed, and the linear velocity of the fabric discharging of the wrapped fabric increases. Thus, the effect that the winding speed is slow when the lifting assembly 34 winds the bottom half circle of the bottom glue and the winding speed is fast when the lifting assembly 34 winds the top half circle of the bottom glue is achieved. The wrapped fabric is wound tighter in the bottom half circle of the triangular belt, avoiding the generation of gaps in the wrapped fabric. The bottom glue will not be deformed due to large tension when winding in the top half circle of the triangular belt.

[0042] Such as Figure 1 And 2As shown, the top surface of the working plate 1 is located at the outer position of the cloth wrapping mechanism 3 and a cloth discharging mechanism 4 is provided. The cloth discharging mechanism 4 includes two third side plates 41. The bottom surface of the third side plate 41 and the working plate 1 are both fixedly connected with a second support column 44. A cloth wrapping winding roller 42 is provided between the two third side plates 41. The two ends of the cloth wrapping winding roller 42 are both fixedly connected with a rotating shaft 43. The rotating shaft 43 is rotatably connected with the third side plate 41. The formed cloth wrapping is wound on the cloth wrapping winding roller 42. One end of the cloth wrapping is wound around the first cloth guide roller 312 for one circle, so that the cloth wrapping rotates along the first cloth guide roller 312 with the rotating ring 311, and is wound between the bottom rubber at the position of the second cloth guide roller 345. The cloth wrapping winding roller 42 itself is not driven by a motor. The cloth wrapping winding roller 42 is unwound by the tension of the cloth wrapping itself when the rotating ring 311 rotates, so that the cloth wrapping winding roller 42 maintains a certain tension during the winding process.

[0043] like Figure 2 and Figure 3 As shown, a conveying mechanism 2 is provided on both outer sides of the cloth wrapping mechanism 3. The conveying mechanism 2 includes a first side plate 22 and a second side plate 24. A bottom glue winding roller 23 is rotatably connected between the first side plate 22 and the second side plate 24. A first motor 25 is provided on the side of the second side plate 24 facing away from the first side plate 22. A fixing bolt 26 is fixedly connected between the first motor 25 and the second side plate 24, and the output end of the first motor 25 passes through the side wall of the second side plate 24 and is fixedly connected to the bottom rubber winding roller 23. A first supporting column 21 is fixedly connected between the working plate 1 and the first side plate 22. A conveying mechanism 2 is installed on both sides of the cloth wrapping mechanism 3. Bottom rubber and rope core are placed on one bottom rubber winding roller 23, and are wound on the bottom rubber winding roller 23 at the other end through the cloth wrapping mechanism 3. The bottom rubber and the wrapping cloth on the bottom rubber winding roller 23 at the other end are combined and wound. When in use, the two first motors 25 are started, so that the first motors 25 drive the bottom rubber winding roller 23 to rotate, so that the bottom rubber winding roller 23 drives the bottom rubber to move at a uniform speed.

[0044] like Figure 5 , Figure 6 and Figure 8As shown, the extrusion assembly 36 includes an extrusion plate 361. Light holes 362 are provided at both ends of the top surface of the extrusion plate 361, and threaded holes 363 are provided at one end of the top surface of the extrusion plate 361 located at the light holes 362. The inner side walls of the light holes 362 are all slidably connected with limiting rods 364, and the inner side walls of the threaded holes 363 are all threadedly connected with limiting rods 364. The bottom ends of the limiting rods 364 are fixedly connected to the support frame 35, the bottom end of the threaded rod 365 is rotatably connected to the support frame 35, and the bottom end of the second motor 33 is fixedly connected to the working plate 1 with a floor bolt 331. When the inclination rate of the hypotenuse of the triangular belt is different, the winding speed of the wrapping cloth released by the second cloth guiding roller 345 also changes accordingly. By rotating the threaded hole 363, the threaded hole 363 drives the extrusion plate 361 to move up and down, changing the height position of the extrusion plate 361. When the arc block 348 is extruded by the extrusion plate 361, the distance that the extrusion plate 361 extrudes the arc block 348 upward changes, changing the distance between the second cloth guiding roller 345 and the center of the rotating ring 311, and changing the winding speed of the wrapping cloth on the second cloth guiding roller 345, thereby achieving the effect of winding the wrapping cloth of triangular belts of different specifications.

[0045] The usage method and working principle of this device: Lay the base rubber of the triangular belt on the rope core, pass the wound base rubber through the center of the rotating ring 311, start the first motor 25, the base rubber winding roller 23 rotates, and the base rubber winding roller 23 drives the base rubber to move at a uniform speed. Start the second motor 33, the second motor 33 drives the second gear 37 to rotate, the second gear 37 drives the first gear 32 to rotate, so that the first gear 32 drives the rotating ring 311 to rotate. A plurality of first cloth guiding rollers 312 are fixed on the side surface of the rotating ring 311, and the rotation of the rotating ring 311 drives the first cloth guiding rollers 312 to rotate. The arc block 348 rotates to the bottom end position of the rotating ring 311, and an extrusion is generated between the arc block 348 and the extrusion plate 361, causing the arc block 348 to move towards the center of the rotating ring 311. A fixing bolt 26 is fixedly connected between the first motor 25 and the second side plate 24, the output end of the first motor 25 penetrates through the side wall of the second side plate 24 and is fixedly connected to the base rubber winding roller 23. A first support column 21 is fixedly connected between the working plate 1 and the first side plate 22. Conveying mechanisms 2 are installed on both sides of the wrapping cloth mechanism 3. A base rubber and a rope core are placed on one base rubber winding roller 23 and are wound on the base rubber winding roller 23 at the other end through the wrapping cloth mechanism 3. The base rubber and the wrapping cloth are combined on the base rubber winding roller 23 at the other end and are wound. When in use, start the two first motors 25, so that the first motor 25 drives the base rubber winding roller 23 to rotate, and the base rubber winding roller 23 drives the base rubber to move at a uniform speed.

[0046] As Figure 5 、 Figure 6 and Figure 8As shown, the extrusion assembly 36 includes an extrusion plate 361. Light holes 362 are provided at both ends of the top surface of the extrusion plate 361, and threaded holes 363 are provided at one end of the top surface of the extrusion plate 361 where the light holes 362 are located. The inner side walls of the light holes 362 are all slidably connected with limiting rods 364, and the inner side walls of the threaded holes 363 are all threadedly connected with limiting rods 364. The bottom ends of the limiting rods 364 are fixedly connected to the support frame 35, the bottom end of the threaded rod 365 is rotatably connected to the support frame 35, and the bottom end of the second motor 33 is fixedly connected to the working plate 1 with a floor bolt 331. When the slope rate of the hypotenuse of the triangular belt is different, the winding speed of the wrapping cloth of the second cloth guiding roller 345 also changes accordingly. By rotating the threaded hole 363, the threaded hole 363 drives the extrusion plate 361 to move up and down, changing the height position of the extrusion plate 361. When the arc block 348 is squeezed by the extrusion plate 361, the distance that the extrusion plate 361 squeezes the arc block 348 upward changes, changing the distance between the second cloth guiding roller 345 and the center of the rotating ring 311, and changing the winding speed of the wrapping cloth on the second cloth guiding roller 345. Thus, the effect of winding the wrapping cloth of triangular belts of different specifications is achieved.

[0047] The usage method and working principle of this device: Lay the base rubber of the triangular belt on the rope core, pass the wound base rubber through the center of the rotating ring 311, start the first motor 25, and the base rubber winding roller 23 rotates, driving the base rubber to move at a uniform speed. Start the second motor 33, the second motor 33 drives the second gear 37 to rotate, the second gear 37 drives the first gear 32 to rotate, causing the first gear 32 to drive the rotating ring 311 to rotate. A plurality of first cloth guiding rollers 312 are fixed on the side surface of the rotating ring 311, and the rotation of the rotating ring 311 drives the first cloth guiding rollers 312 to rotate. The arc block 348 rotates to the bottom end position of the rotating ring 311, and an extrusion is generated between the arc block 348 and the extrusion plate 361, causing the arc block 348 to move towards the center of the rotating ring 311.
