Description

Technical Field

[0001] This utility model relates to the field of heat-sealing splicing technology for rubber conveyor belts, specifically a heat-sealing splicing device for rubber conveyor belts. Background Technology

[0002] In modern industrial production, rubber conveyor belts are widely used as an important material handling device in many fields such as mining, ports, power, chemicals, and building materials. They can efficiently and stably transport materials over long distances, greatly improving production efficiency and reducing labor costs. However, in actual use, because the required length of rubber conveyor belts is often determined according to specific production scenarios, splicing of the conveyor belts is frequently necessary.

[0003] According to announcement number CN 215283410 U, a rubber conveyor belt heat-sealing splicing device is disclosed. The rubber conveyor belt heat-sealing splicing device includes a base plate; a shell, the bottom of which is fixedly connected to the top of the base plate; two bearing plates, the opposite sides of which are fixedly connected to the left and right sides of the inner wall of the shell; two fixing components, the bottoms of which are fixedly connected to the left and right sides of the top of the two bearing plates; and a cooling component, the right side of which is fixedly connected to the top of the left side of the shell.

[0004] This device, through the coordinated use of components within the fixing assembly, allows for the rapid securing of conveyor belts to be spliced, significantly improving splicing efficiency. The coordinated use of components within the cooling assembly enables rapid cooling of the conveyor belts after heat sealing, further enhancing efficiency. However, this device only clamps and secures the rubber conveyor belts; it cannot adjust their position. This means the conveyor belts cannot be placed in the appropriate heat sealing position, thus impacting operational efficiency. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rubber conveyor belt heat sealing and splicing device, including a base, a support leg fixedly connected to the bottom of the base, a movable clamping mechanism provided at the bottom of the base, and a heat sealing mechanism provided at the top of the base;

[0007] The movable clamping mechanism includes a first fixed frame, which is fixedly connected to the bottom of the base. Bidirectional lead screws are rotatably connected to the left and right sides of the first fixed frame near the bottom. A first servo motor is fixedly connected to the right side of the first fixed frame near the bottom.

A second servo motor is fixedly connected to one side of the fixed plate. A gear is fixedly connected to the surface of the output shaft of the second servo motor.

[0008] Preferably, the output end of the first servo motor is fixedly connected to the right end of the bidirectional lead screw. The left side of the moving block is symmetrically provided with holes that match the limiting rod. The moving block is slidably connected to the surface of the limiting rod through the holes. The limiting rod limits the two moving blocks, so that the two moving blocks move towards each other as the bidirectional lead screw rotates.

[0009] Preferably, the top left and right sides of the base are provided with grooves that match the direction of the movable block, and the surface of the movable block is penetrated and slidably connected to the grooves.

[0010] Preferably, the top of the second fixing frame has a hole that matches the cylindrical rack, and the surface of the cylindrical rack is penetrated and slidably connected to the hole.

[0011] Preferably, the gear meshes with a cylindrical rack, and the bottom of the pressure block has a raised shape, which facilitates more stable clamping of the rubber conveyor belt.

[0014] Compared with the prior art, this utility model provides a rubber conveyor belt heat sealing and splicing device, which has the following beneficial effects:

[0015] This rubber conveyor belt heat-sealing and splicing device features a moving clamping mechanism driven by a first servo motor and a bidirectional lead screw, enabling rapid and precise adjustment of the positions of two moving blocks. Limiting rods restrict the movement of the moving blocks, ensuring stable relative movement towards each other as the bidirectional lead screw rotates. This facilitates quick and easy placement of the rubber conveyor belt in the appropriate heat-sealing position, significantly improving operational efficiency. A second servo motor drives a gear that meshes with a cylindrical rack, controlling the lifting and lowering of the pressure block. The bottom of the pressure block has a raised shape, providing a more stable clamping force when holding the rubber conveyor belt, ensuring no displacement of the conveyor belt during heat sealing and guaranteeing the quality of the heat-sealing and splicing.

[0016] This rubber conveyor belt heat-sealing and splicing device uses two hydraulic cylinders to drive a first hot-pressing plate downwards, which cooperates with a fixed second hot-pressing plate to heat-seal the rubber conveyor belt. By precisely controlling the stroke and pressure of the hydraulic cylinders, uniform pressure distribution can be ensured during the heat-sealing process, resulting in even heating of the conveyor belt splice and improving the strength and consistency of the splice.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] This utility model provides the following technical solution: Example 1

[0026] Please see Figure 1-3 This utility model provides a technical solution: a rubber conveyor belt heat sealing splicing device, including a base 1, a support leg 2 fixedly connected to the bottom of the base 1, a movable clamping mechanism 3 provided at the bottom of the base 1, and a heat sealing mechanism 4 provided at the top of the base 1.

[0027] The movable clamping mechanism 3 includes a first fixed frame 31, which is fixedly connected to the bottom of the base 1. Bidirectional lead screws 32 are rotatably connected to the left and right sides of the first fixed frame 31 near the bottom. A first servo motor 33 is fixedly connected to the right side of the first fixed frame 31 near the bottom. Limiting rods 34 are symmetrically fixedly connected to the left and right sides of the first fixed frame 31 near the bottom. Moving blocks 35 are symmetrically threaded on the surface of the bidirectional lead screws 32. Moving seats 36 are fixedly connected to the top of the moving blocks 35. A second fixed frame 37 is fixedly connected to the top of the moving seats 36. A sliding sleeve 38 is fixedly connected to the top of the second fixed frame 37. A cylindrical rack 39 is slidably connected up and down inside the sliding sleeve 38. A pressure block 311 is fixedly connected to the bottom end of the cylindrical rack 39. A fixed plate 312 is fixedly connected to the top of the second fixed frame 37. A second servo motor 313 is fixedly connected to one side of the fixed plate 312. A gear 314 is fixedly connected to the surface of the output shaft of the second servo motor 313.

[0028] The output end of the first servo motor 33 is fixedly connected to the right end of the bidirectional lead screw 32. The moving block 35 has symmetrical holes on the left side that match the limiting rod 34. The moving block 35 is slidably connected to the surface of the limiting rod 34 through the holes. The limiting rod 34 limits the two moving blocks 35, so that the two moving blocks 35 move towards each other as the bidirectional lead screw 32 rotates.

[0029] The top left and right sides of the base 1 have slots that match the moving block 35, and the surface of the moving block 35 is slidably connected to the slots.

[0030] The top of the second fixing bracket 37 has a hole that matches the cylindrical rack 39, and the cylindrical rack 39 is slidably connected to the hole by passing through its surface.

[0031] The gear 314 meshes with the cylindrical rack 39, and the bottom of the pressure block 311 is convex, which makes it easier to clamp the rubber conveyor belt more stably. Example 2

[0032] Please see Figure 4 Furthermore, based on Example 1, a heat-sealing mechanism 4 was obtained.

[0033] The heat sealing mechanism 4 includes a third fixed frame 41, which is fixedly connected to the top of the base 1. Hydraulic cylinders 42 are symmetrically fixedly connected to the top of the third fixed frame 41. A first hot press plate 43 is fixedly connected to the output end of the hydraulic cylinder 42. Guide rods 44 are symmetrically fixedly connected to the top of the first hot press plate 43. A second hot press plate 45 is fixedly connected to the top of the base 1.

[0034] The top of the third fixing frame 41 has a hole that matches the guide rod 44, and the guide rod 44 passes through the surface and slides up and down in the hole. The first hot press plate 43 can move more stably by sliding the guide rod 44 up and down in the hole.

[0035] In actual operation, when this device is used, before preparing to splice the rubber conveyor belt, the first servo motor 33 is started. The operation of the first servo motor 33 drives the bidirectional lead screw 32 to rotate within the first fixed frame 31. The moving block 35 slides left and right on the surface of the limiting rod 34 through the holes symmetrically opened on its left side that match the limiting rod 34. At the same time, under the thread transmission of the bidirectional lead screw 32, the two moving blocks 35 move towards or in opposite directions along the limiting rod 34. In this way, the moving seat 36 and the second fixed frame 37 connected to it are moved to the appropriate position to prepare for placing the rubber conveyor belt. The rubber conveyor belt to be spliced ​​is placed on the corresponding position on the base 1, and the second servo motor 313 is started. The output shaft of the second servo motor 313 drives the gear 314 to rotate. Since the gear 314 meshes with the cylindrical rack 39, the cylindrical rack 39 drives the pressure block 311 to move downward under the drive of the gear 314. The bottom of the pressure block 311 is convex, which can press tightly onto the rubber conveyor belt, providing a stable clamping force and ensuring that the conveyor belt will not shift during the subsequent heat sealing process;

[0036] After the rubber conveyor belt is fixed in position by the movable clamping mechanism 3, the heat sealing mechanism 4 begins to operate. The third fixing frame 41 is fixed to the top of the base 1, and the hydraulic cylinders 42, which are symmetrically fixed on it, are activated. The output end of the hydraulic cylinders 42 pushes the first hot press plate 43 downward. The guide rods 44, which are symmetrically connected to the top of the first hot press plate 43, slide up and down in the holes opened on the top of the third fixing frame 41 to ensure the stable movement of the first hot press plate 43. The downward movement of the first hot press plate 43 cooperates with the second hot press plate 45 fixed to the top of the base 1 to apply pressure to the joint of the rubber conveyor belt placed between the two. At the same time, the first hot press plate 43 and the second hot press plate 45 begin to work, heating the joint of the rubber conveyor belt. Under the action of appropriate temperature and pressure, the rubber at the joint of the rubber conveyor belt undergoes a vulcanization reaction, realizing the heat sealing joint.
