Description

Technical Field

[0001] This invention belongs to the field of conveyor belt processing technology, specifically a heat-sealing and splicing device for rubber conveyor belts. Background Technology

[0002] Rubber conveyor belts possess properties such as heat resistance, abrasion resistance, and burn resistance, and are mainly used for material transportation in mines, metallurgy, steel, and coal industries. Currently, to meet the needs of long-distance transportation, rubber conveyor belts require heat-sealing splicing of two or more sections.

[0003] In existing technologies, the heat-sealing splicing of two rubber conveyor belts usually involves first butt-jointing the two conveyor belts together, and then using a hot press plate to heat and press the butt joint of the two conveyor belts. When heated, the two conveyor belts melt and stick together under pressure, thus completing the heat-sealing splicing operation. However, this heat-sealing splicing method is relatively traditional. Because the contact area between the two conveyor belts after butt joint is small, the connection strength between the two conveyor belts is relatively low. This makes the conveyor belts prone to breakage at the splicing position under the heavy pressure of materials, which affects the conveying of materials. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a rubber conveyor belt heat sealing and splicing device.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A rubber conveyor belt heat-sealing and splicing device includes a splicing table, a clamping assembly, a punching assembly, a hot-pressing assembly, and a drive assembly. A support plate is fixedly installed on the upper part of the splicing platform. The clamping assembly is provided in two sets, which are respectively located on the left and right sides of the upper part of the splicing platform, and are used to clamp the two sets of conveyor belts respectively. The drive assembly is installed at the bottom of the splicing platform and is used to drive the two sets of clamping assemblies to move towards each other. The punching assembly and the hot pressing assembly are mounted on the side wall of the support plate. The punching assembly is used to punch the ends of the two sets of conveyor belts, so that one set of conveyor belt ends forms several recesses, and the other set of conveyor belt ends forms several protrusions that match the recesses. The hot pressing assembly is used to perform hot pressing treatment on the two sets of conveyor belts after punching.

The two sets of threaded sections are opened outside the rotating shaft and are threadedly engaged with the two sets of the first slide rods respectively. The two sets of threaded sections have opposite directions of rotation.

[0009] As a further improvement of the present invention: the splicing platform is provided with a plurality of first punches and a plurality of second punches, and the plurality of first punches and the plurality of second punches are distributed sequentially at intervals along the front-back direction of the splicing platform. The punching assembly includes a first punch, a ring plate, a second hydraulic cylinder, and a second punch. The second hydraulic cylinder is fixedly mounted on the inner top wall of the support plate. The annular plate is disposed at the output end of the second hydraulic cylinder. Several sets of the first punch and the first punch hole are provided in a one-to-one correspondence, and several sets of the second punch and the second punch hole are provided in a one-to-one correspondence. A number of first punches and a number of second punches are fixedly installed at the bottom of the ring plate, and each group of first punches and each group of second punches is provided with a cutting edge at the bottom.

[0010] As a further improvement of the present invention: the hot pressing assembly includes a third hydraulic cylinder, a first hot pressing plate, and a second hot pressing plate. The third hydraulic cylinder is fixedly installed on the inner top wall of the support plate, the first hot press plate is disposed at the output end of the third hydraulic cylinder, and the second hot press plate is embedded on the upper surface of the splicing platform and located directly below the first hot press plate.

[0011] As a further improvement of the present invention: the upper part of the splicing platform is also provided with a rolling assembly. After the two sets of conveyor belts are spliced ​​by correspondingly inserting several protrusions and several recesses, the rolling assembly is used to roll the splicing position of the two sets of conveyor belts to flatten the inserted protrusions and several recesses.

[0012] As a further improvement to the present invention: the rolling assembly includes a roller and a power component.

Subsequently, the punching component punches one end of the two sets of conveyor belts, so that the end of one set of conveyor belts forms several recesses, and the end of the other set of conveyor belts forms several protrusions that match the recesses. Then, the driving component drives the two sets of clamping components to move towards each other, thereby driving the two sets of conveyor belts to move towards each other. When the two sets of conveyor belts move towards each other, the several protrusions... The assembly should extend into several recessed areas to complete the splicing of the two conveyor belts. Then, the hot pressing assembly performs hot pressing on the spliced ​​two conveyor belts to complete the heat-sealing splicing of the two conveyor belts. After the two conveyor belts are heat-sealed, the contact area between the two conveyor belts can be increased due to the joint between several protrusions and several recessed areas, thereby improving the splicing strength and quality of the two conveyor belts. Compared with the existing technology, when heat-sealing two conveyor belts, the contact area between the two conveyor belts can be increased, thereby improving the connection strength after the heat-sealing splicing of the two conveyor belts and meeting the material bearing requirements.

[0021] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4This embodiment provides a rubber conveyor belt heat-sealing splicing device, including a splicing platform 10, a clamping assembly 20, a punching assembly 30, a hot-pressing assembly 40, and a driving assembly 50. A support plate 105 is fixedly mounted on the upper part of the splicing platform 10. Two sets of clamping assemblies 20 are provided, respectively disposed on the left and right sides of the upper part of the splicing platform 10, for clamping two sets of conveyor belts 70. The driving assembly 50 is installed at the bottom of the splicing platform 10 and is used to drive the two sets of clamping assemblies 70. The clamping components 20 move toward each other, and the punching component 30 and the hot pressing component 40 are mounted on the side wall of the support plate 105. The punching component 30 is used to punch the ends of the two sets of conveyor belts 70, so that the ends of one set of conveyor belts 70 form a plurality of recesses 701, and the ends of the other set of conveyor belts 70 form a plurality of protrusions 702 that are adapted to the recesses 701. The hot pressing component 40 is used to perform hot pressing treatment on the two sets of conveyor belts 70 after punching.

[0022] When heat-sealing two sets of conveyor belts 70 is required, the two sets of conveyor belts 70 can be placed on the upper left and right sides of the splicing table 10, respectively. Then, two sets of clamping components 20 are used to clamp the two sets of conveyor belts 70. At this time, the two sets of conveyor belts 70 are relatively distributed. Subsequently, the punching component 30 punches one end of the two sets of conveyor belts 70, so that the end of one set of conveyor belts 70 forms several recesses 701, and the end of the other set of conveyor belts 70 forms several protrusions 702 that are adapted to the recesses 701 (e.g., ...). Figure 4 As shown), the drive assembly 50 then drives the two sets of clamping assemblies 20 to move towards each other, which in turn drives the two sets of conveyor belts 70 to move towards each other. When the two sets of conveyor belts 70 move towards each other, a number of protrusions 702 extend into the interior of a number of recesses 701, and the two sets of conveyor belts 701 are spliced. Then, the hot pressing assembly 40 performs hot pressing on the spliced ​​two sets of conveyor belts 70, thereby completing the heat sealing splicing of the two sets of conveyor belts 70. After the two sets of conveyor belts 70 are heat sealed spliced, due to the joint between the number of protrusions 702 and the number of recesses 701, the contact area between the two sets of conveyor belts 70 can be increased, thereby improving the splicing strength and splicing quality of the two sets of conveyor belts 70.

[0023] Please see Figure 1 In one embodiment, the two sets of clamping components 20 have the same structure, each including a U-shaped clamping plate 201, a first hydraulic cylinder 202, and a pressure plate 203. The U-shaped clamping plate 201 is movably disposed on the upper part of the splicing table 10, and the pressure plate 203 is disposed on the inner side of the U-shaped clamping plate 201. The first hydraulic cylinder 202 is installed on the upper part of the U-shaped clamping plate 201 and is used to drive the pressure plate 203 to move up and down.

[0024] By placing the conveyor belt 70 inside the U-shaped clamp 201, the first hydraulic cylinder 202 drives the pressure plate 203 to move down along the inside of the U-shaped clamp 201, thereby pressing the conveyor belt 70 onto the bottom wall of the inside of the U-shaped clamp 201, thus completing the clamping of the conveyor belt 70. After the conveyor belt 70 is clamped, the punching component 30 punches the ends of the conveyor belt 70, so that the ends of one set of conveyor belts 70 form several recesses 701, and the ends of the other set of conveyor belts 70 form several protrusions 702 that are adapted to the recesses 701. Then, the drive component 50 drives the U-shaped clamp 201, the first hydraulic cylinder 202 and the pressure plate 203 to move along the upper part of the splicing table 10, thereby driving the conveyor belt 70 to move, so that the protrusions 702 are inserted into the recesses 701, thereby completing the splicing operation of the two sets of conveyor belts 70.

[0025] Please see Figure 1 In one embodiment, the splicing platform 10 has two sets of sinks 101 on its upper part, and the bottoms of the two sets of U-shaped clamps 201 extend into the sinks 101 respectively.

[0026] By extending the bottom of the U-shaped clamp 201 into the interior of the settling tank 101, and pressing the conveyor belt 70 against the inner bottom wall of the U-shaped clamp 201 by the pressure plate 203, the conveyor belt 70 can adhere to the upper surface of the splicing table 10. This ensures that after the two sets of conveyor belts 70 move and are spliced, the two sets of conveyor belts 70 can remain on the same horizontal plane, thereby ensuring the flatness of the two sets of conveyor belts 70 after heat sealing.

[0027] Please see Figure 1 as well as Figure 2 In one embodiment, the bottom of each of the two sets of sinks 101 is provided with a first sliding groove 102 extending to the lower surface of the splicing platform 10. The bottom of each of the two sets of U-shaped clamps 201 is fixedly provided with a first sliding rod 204. The two sets of first sliding rods 204 extend from the two sets of first sliding grooves 102 to the bottom of the splicing platform 10. The drive assembly 50 includes a first motor 501, a rotating shaft 502, and a threaded section 503. The first motor 501 is fixedly installed at the bottom of the splicing platform 10. One end of the rotating shaft 502 is connected to the output end of the first motor 501, and the other end passes through the two sets of first sliding rods 204. There are two sets of threaded sections 503. The two sets of threaded sections 503 are opened outside the rotating shaft 502 and are threadedly engaged with the two sets of first sliding rods 204 respectively. The two sets of threaded sections 503 rotate in opposite directions.

[0028] When the punching assembly 30 punches the ends of the conveyor belts 70, forming several recesses 701 at the ends of one set of conveyor belts 70 and several protrusions 702 that match the recesses 701 at the ends of the other set of conveyor belts 70, the first motor 501 drives the rotating shaft 502 to rotate. Through the threaded engagement of the two sets of threaded sections 503 and the two sets of first slide rods 204, the two sets of first slide rods 204 slide towards each other along their respective first slide grooves 102. The two sets of first slide rods 204 drive the two sets of U-shaped clamps 201 to move towards each other, thereby driving the two sets of conveyor belts 70 to move towards each other, so that the protrusions 702 and the recesses 701 are correspondingly inserted, thereby completing the splicing operation between the two sets of conveyor belts 70.

[0029] Please see Figure 1 , Figure 2 as well as Figure 6 In one embodiment, the splicing platform 10 is provided with a plurality of first punches 103 and a plurality of second punches 104. The plurality of first punches 103 and the plurality of second punches 104 are distributed sequentially at intervals along the front-back direction of the splicing platform 10. The punching assembly 30 includes a first punch 301, a ring plate 302, a second hydraulic cylinder 303 and a second punch 304. The second hydraulic cylinder 303 is fixedly installed on the inner top wall of the support plate 105. The ring plate 302 is disposed at the output end of the second hydraulic cylinder 303. A plurality of groups of first punches 301 are provided in correspondence with the first punches 103. A plurality of groups of second punches 304 are provided in correspondence with the second punches 104. A plurality of first punches 301 and a plurality of second punches 304 are fixedly installed at the bottom of the ring plate 302. Each group of first punches 301 and each group of second punches 304 is provided with a cutting edge 305 at the bottom.

[0030] After placing the two sets of conveyor belts 70 inside the two sets of U-shaped clamps 201, the operator can adjust the positions of the two sets of conveyor belts 70 so that the end of one set of conveyor belts 70 is above several first punches 103, and the end of the other set of conveyor belts 70 is above several second punches 104. Then, the first hydraulic cylinder 202 drives the pressure plate 203 to move down to press and fix the two sets of conveyor belts 70. Then, the second hydraulic cylinder 303 drives the ring plate 302 to move down, thereby driving several first punches 301 and several second punches 304 to move down. When the several first punches 301 move down, their bottom cutting edges 305 extend into the several first punches 103 to punch and cut the end of one set of conveyor belts 70, thus making one set of conveyor belts 70... Several recesses 701 are formed at the ends of the conveyor belt 70. When several second punches 304 move down, their bottom cutting edges 305 extend into several second punch holes 104 to punch the ends of the other conveyor belt 70, so that several protrusions 702 are formed at the ends of the other conveyor belt 70. After the ends of the two conveyor belts 70 are punched, the second hydraulic cylinder 303 drives the ring plate 302 to move up, which in turn drives several first punches 301 and several second punches 304 to move up. Then the first motor 501 drives the rotating shaft 502 to rotate, which in turn drives the two U-shaped clamps 201 and the two conveyor belts 70 to move towards each other, so that several protrusions 702 are inserted into several recesses 701, thereby completing the splicing between the two conveyor belts 70.

[0031] Please see Figure 1 In one embodiment, the hot pressing assembly 40 includes a third hydraulic cylinder 401, a first hot pressing plate 402, and a second hot pressing plate 403. The third hydraulic cylinder 401 is fixedly installed on the inner top wall of the support plate 105. The first hot pressing plate 402 is disposed at the output end of the third hydraulic cylinder 401. The second hot pressing plate 403 is embedded in the upper surface of the splicing platform 10 and located directly below the first hot pressing plate 402.

[0032] When several protrusions 702 and several recesses 701 are inserted to splice the two sets of conveyor belts 70, the ends of the two sets of conveyor belts 70 act on the upper part of the second hot press plate 403. At this time, the third hydraulic cylinder 401 drives the first hot press plate 402 to move downward. When the first hot press plate 402 moves downward, it acts on the splicing position of the two sets of conveyor belts 70 and presses the splicing position of the two sets of conveyor belts 70 onto the upper part of the second hot press plate 403. At this time, the first hot press plate 402 and the second hot press plate 403 heat the splicing position of the two sets of conveyor belts 70, thereby realizing the hot pressing joint of the two sets of conveyor belts 70.

[0033] Because the conveyor belt 70 is made of rubber, it is relatively flexible. After the protrusions 702 and recesses 701 are interlocked to join the two sets of conveyor belts 70, misalignment can easily occur between them. This results in an uneven joint between the two sets of conveyor belts 70 after the first hot press plate 402 moves downward to heat-press the two sets of conveyor belts 70 together, thus affecting the quality of the joint. Therefore, please refer to [link / reference needed]. Figure 3 In one embodiment, the splicing platform 10 is further provided with a rolling assembly 60. After the two sets of conveyor belts 70 are spliced ​​by correspondingly inserting several protrusions 702 and several recesses 701, the rolling assembly 60 is used to roll the splicing position of the two sets of conveyor belts 70 to flatten the inserted protrusions 702 and several recesses 701, so that the protrusions 702 and several recesses 701 can be smoothly inserted. In this way, when the first hot press plate 402 moves down, the two sets of conveyor belts 70 can be accurately pressed into one piece, thereby improving the joining quality of the two sets of conveyor belts 70.

[0034] Please see Figure 7 In one embodiment, the rolling assembly 60 includes a roller 601 and a power component. The roller 601 is disposed above the splicing platform 10, and the power component is mounted on the side wall of the support plate 105 to drive the roller 601 to move horizontally reciprocally above the splicing platform 10. When the roller 601 moves horizontally reciprocally, it acts on the upper surfaces of a plurality of interlocking protrusions 702 and a plurality of interlocking recesses 701, thereby realizing the rolling treatment of the plurality of protrusions 702 and the plurality of interlocking recesses 701, so that the plurality of protrusions 702 and the plurality of interlocking recesses 701 can be smoothly inserted and ensure that the plurality of protrusions 702 and the plurality of interlocking recesses 701 remain flush after insertion.

[0035] Please see Figure 7 In one embodiment, the power component includes a second slide rod 602, a lever 604, a support plate 605, and a second motor 606. The second slide rod 602 is slidably disposed on the side wall of the bracket plate 105 and is vertically distributed. The roller 601 is rotatably disposed on one side of the second slide rod 602. A second groove 603 is vertically distributed on the side of the second slide rod 602 away from the roller 601. The second motor 606 is fixedly mounted on the side wall of the bracket plate 105. One end of the support plate 605 is connected to the output end of the second motor 606, and the other end is fixedly connected to the lever 604. The lever 604 extends into the second groove 603 and slides in cooperation with the second groove 603.

[0036] After the protrusions 702 and the recesses 701 are correspondingly inserted to splice the two sets of conveyor belts 70, the second motor 606 drives the support plate 605 to rotate. The support plate 605 drives the lever 604 to move in a circular motion. When the lever 604 moves in a circular motion, it pushes the second slide bar 602 to slide horizontally back and forth relative to the side wall of the support plate 105 through the sliding cooperation with the second slide groove 603. When the second slide bar 602 slides horizontally back and forth, it drives the roller 601 to move horizontally back and forth along the upper part of the splicing platform 10, thereby performing rolling treatment on the protrusions 702 and the recesses 701 that are inserted into each other, so that the protrusions 702 and the recesses 701 are accurately inserted and aligned.

[0037] Please see Figure 5 In one embodiment, a horizontally distributed slide rail 106 is fixedly provided on the side wall of the support plate 105, and a slider 607 is fixedly provided at one end of the second slide rod 602, the slider 607 slidingly engaging with the slide rail 106.

[0038] Through the sliding cooperation between the slider 607 and the slide rail 106, the lever 604 can push the second slide bar 602 to move horizontally back and forth when it moves in a circular motion. This, in turn, drives the roller 601 to move horizontally back and forth above the splicing platform 10, so as to roll the upper surfaces of the interlocking protrusions 702 and the interlocking recesses 701, thereby ensuring that the protrusions 702 and the recesses 701 can be accurately interlocked and aligned.

[0039] In this embodiment of the invention, when it is necessary to heat-seal and splice two sets of conveyor belts 70, the two sets of conveyor belts 70 can be placed on the upper left and right sides of the splicing table 10, respectively. Then, two sets of clamping components 20 are used to clamp the two sets of conveyor belts 70 respectively. At this time, the two sets of conveyor belts 70 are relatively distributed. Subsequently, the punching component 30 punches one end of the two sets of conveyor belts 70, so that the end of one set of conveyor belts 70 forms several recesses 701, and the end of the other set of conveyor belts 70 forms several protrusions 702 that are adapted to the recesses 701 (e.g., ...). Figure 4As shown in the diagram, the drive assembly 50 then drives the two clamping assemblies 20 to move towards each other, which in turn drives the two conveyor belts 70 to move towards each other. When the two conveyor belts 70 move towards each other, several protrusions 702 extend into several recesses 701, and the two conveyor belts 701 are spliced ​​together. Then, the hot pressing assembly 40 performs hot pressing on the spliced ​​two conveyor belts 70, thereby completing the heat-sealing splicing of the two conveyor belts 70. After the two conveyor belts 70 are heat-sealed, the contact area between the two conveyor belts 70 is increased due to the engagement between the several protrusions 702 and the several recesses 701, thereby improving the splicing strength and quality of the two conveyor belts 70. Compared with the prior art, when heat-sealing the two conveyor belts 70, the contact area between the two conveyor belts 70 can be increased, thereby improving the connection strength after the heat-sealing splicing of the two conveyor belts 70, and thus meeting the material bearing requirements.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity, and those skilled in the art should consider the specification as a whole.
