Description

Technical Field

[0002] Rubber sheet is a versatile and practical industrial material, widely used in many fields such as construction, automobiles, electronic equipment, aerospace and shipbuilding. It has excellent elasticity, wear resistance, aging resistance and chemical corrosion resistance. It also has good insulation properties and can play an important protective role in electrical equipment. During the processing of rubber sheet, it may be necessary to weld two or more rubber sheets together because its thickness does not meet the requirements. Hot plate welding machine is a commonly used equipment for welding rubber sheets.

[0003] When the existing hot plate welding machine is in use, the opposite sides of the two rubber plates are heated and melted, and then after extrusion, molten rubber will be squeezed out at the edges where the two rubber plates are connected.

[0061] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] See also Figure 1-14In an embodiment of the present invention, a welding device for processing a rubber sheet includes a frame 1, two fixing mechanisms 2, a trimming mechanism 3, and a discharge mechanism 4. The frame 1 is installed on the ground. A layer plate is fixedly connected inside the frame 1. The top surface of the layer plate and the inner top surface of the frame 1 are fixedly connected with an extrusion mechanism 11. A heating mechanism 12 is slidably connected inside the frame 1 and between the two extrusion mechanisms 11. Pads 13 are rotatably connected to both sides of the extrusion mechanism 11. The two fixing mechanisms 2 are respectively arranged inside the extrusion mechanisms 11 at corresponding positions for fixing the rubber sheet. The trimming mechanism 3 It is arranged between the layer plate and the bottom surface of the frame 1, and is used to cut off the protruding part of the connection of the rubber plate after welding. The trimming mechanism 3 includes a bottom frame 31, and the bottom surface of the bottom frame 31 is provided with a centering component 32 for centering the rubber plate after welding. The bottom surface of the bottom frame 31 is provided with a lifting component 33 for fixing the rubber plate after welding and for detaching from the bottom surface of the bottom frame 31. The inside of the bottom frame 31 is provided with a moving component 34 for cutting the protruding part of the connection of the rubber plate after welding. The unloading mechanism 4 is arranged below the trimming mechanism 3, and is used to move the rubber plate after trimming out of the inside of the frame 1.

[0063] Specifically, firstly, rubber sheets are placed on the two extrusion mechanisms 11 respectively, and the two rubber sheets are aligned, and then the two rubber sheets are fixed by the two fixing mechanisms 2, and the heating mechanism 12 is moved between the two rubber sheets, and then the two extrusion mechanisms 11 are brought close to each other, so that the two rubber sheets are in close contact with the heating mechanism 12 (the heating mechanism 12 and the extrusion mechanism 11 are prior art, so no further description is given), so that the side of the rubber sheet in contact with the heating mechanism 12 is melted, and then the two extrusion mechanisms 11 are separated by one end, and the heating mechanism 12 is moved away from between the two rubber sheets, and then the two extrusion mechanisms 11 are moved close to each other again. The extrusion mechanisms 11 are close to each other and make the melted side surfaces of the two rubber plates closely contact, so that the two rubber plates are welded together, and then the two rubber plates are released by the two fixing mechanisms 2. At this time, the two rubber plates welded together contact the two pads 13 in the place under the action of their own gravity. When the two extrusion mechanisms 11 are restored to their original positions, the welded rubber plates are dropped into the bottom frame 31 by the rotation of the two pads 13. After the welded rubber plates are moved to the center position of the bottom frame 31 by the centering assembly 32, the welded rubber plates are first fixed by the lifting assembly 33 (at the same time, the two rubber plates can be fixed at the same time). The rubber sheet to be welded is placed in the extrusion mechanism 11), and then the centering component 32 is restored to its original position, and the protruding part of the connection between the two welded rubber sheets is cut off by the moving component 34. After the protruding part is cut off, the welded rubber sheet is lifted up by the jacking component 33, and at the same time, the unloading mechanism 4 is moved to the inside of the frame 1, and then the jacking component 33 is moved downward, so that the welded rubber sheet falls on the unloading mechanism 4, and at the same time, the unloading mechanism 4 moves the rubber sheet of the welding mechanism out of the inside of the frame 1. The staff can place a collection box under the unloading mechanism 4 to remove the rubber sheet from the inside of the frame 1. The rubber sheet falls into the collection box and is reciprocated by the above-mentioned operation method. The staff only needs to load the materials into the two extrusion mechanisms 11 without manual unloading. They only need to take out the rubber sheets in the collection box regularly, thereby improving the efficiency of rubber sheet welding. The device can cut off the protruding part of the connection between the two rubber sheets through the coordinated use of the centering component 32, the lifting component 33 and the moving component 34. There is no need for manual cleaning with a sharp tool, thereby avoiding the danger of the staff during cleaning and saving labor costs. In addition, automatic cleaning is more efficient than manual cleaning.

[0066] In this embodiment, a rubber sheet to be welded is firstly taken and placed in the bottom frame 31, and then the four cutter heads 343 are moved so as to align the cutter heads 343 with the corresponding side surfaces of the rubber sheet. After the four cutter heads 343 are aligned, the rubber sheet to be welded is taken away, and the four round rollers 347 can be driven by the right-angle motor 349 to rotate. The rotation of the round rollers 347 can reel up the pull rope 1 348 at the corresponding position, so that the rectangular sleeve 341 at the corresponding position can be moved inside the slide hole 2 313 at the corresponding position (such as Fig.12 As shown, the four cutter heads 343 move in the clockwise direction at the same time), and the spring 1 346 at the corresponding position pulls the rope. The moving cutter head 343 can cut off the protruding part of the connection of the welded rubber plate, and then through the reverse drive of the right-angle motor 349, the right-angle motor 349 no longer applies tension to the pull rope 1 348, and the rectangular sleeve 341 returns to its original position under the elastic action of the spring 1 346 at the corresponding position, and then the rubber plate with the protruding part cleaned is moved out from the inside of the frame 1 under the action of the lifting assembly 33 and the unloading mechanism 4.

[0069] Embodiment 2

[0070] like Fig. 9 and Fig.10 As shown, in this embodiment, four sliding holes 315 are opened through the bottom surface of the bottom frame 31, and the four sliding holes 315 are in a cross-shaped structure. A support block 2 316 is fixedly connected to the bottom surface of the bottom frame 31 corresponding to the sliding hole 315, and a shell 317 is fixedly connected to the bottom surface of the bottom frame 31. The centering component 32 includes four push plates 321, four screw rods 322, four bevel gears 1 323, and a drive motor 1 324. The four push plates 321 are respectively slidably connected to the inside of the sliding hole 315 at the corresponding positions, and the four screw rods 322 are rotatably connected between the support block 2 316 and the shell 317 at the corresponding positions, and are screwed through and connected with the push plates 321 at the corresponding positions. One end of the screw rod 322 passes through the shell 317 and extends to the interior of the shell 317. One end of the outer wall of the screw rod 322 is provided with a plurality of hemispherical grooves at equal angles. Four bevel gears 323 are respectively arranged at one end of the screw rod 322 at corresponding positions and are located inside the shell 317.

The output end of the drive motor 324 passes through the inner bottom surface of the shell 317 and is fixedly connected with a bevel gear 2 325 that meshes with the four bevel gears 323.

[0071] In this embodiment, the bevel gear 2 325 can drive the multiple bevel gears 1 323 to rotate by starting the driving motor 1 324. Since the spring steel ball is engaged with the hemispherical groove at the corresponding position, the rotating bevel gear 1 323 can make the screw rod 322 at the corresponding position rotate, and the rotating screw rod 322 can make the push plate 321 at the corresponding position move in the sliding hole 315 at the corresponding position, so that the rubber plate dropped into the bottom frame 31 can be moved toward the middle. When the position of one of the moving directions of the rubber plate reaches the limit, the bevel gear 1 323 at the corresponding position rotates, but under the action of the spring steel ball and the hemispherical groove, the screw rod 322 at the corresponding position will not rotate due to the reverse force of the rubber plate, while the two push plates 321 at the other movable direction can still move until the rubber plate moves to the center position of the bottom frame 31.

Convex blocks 431 are fixedly connected to both side surfaces of the connecting frame 43. The two L-shaped frames 44 are respectively fixedly connected to the side surfaces of the lower sliders 41. The round rod 45 is rotatably connected between the two L-shaped frames 44. The conveyor belt 46 is rollingly sleeved between the round rod 45 and the rotating rod. The second driving motor 47 is fixedly connected to the side surface of one of the L-shaped frames 44. The output end of the second driving motor 47 penetrates through the corresponding L-shaped frame 44 and is fixedly connected to the round rod 45. The two second sliding rods 48 are fixedly connected between the two fixing blocks 19 at corresponding positions and penetrate through and slide with the corresponding convex blocks 431. A second spring 481 is fixedly connected between the fixing block 19 and the corresponding convex block 431. The two second pulling ropes 49 are respectively fixedly connected to the side surfaces of the corresponding convex blocks 431 and are fixedly connected to the connecting plate 334. The second pulling ropes 49 penetrate through the side surface of the frame body 1, and an anti-slip sleeve is provided at the connection between the second pulling ropes 49 and the frame body 1.

[0080] In this embodiment, by starting the four cylinders 331, the rubber plate in the bottom frame 31 can be lifted. When the lifted rubber plate moves above the conveyor belt 46, at this time, the two second pulling ropes 49 are in a taut state. Then, with the continuous upward movement of the four cylinders 331, since one end of the second pulling rope 49 is fixed to the convex block 431, the continuous upward movement of the cylinder 331 can drive the two connecting frames 43 to move until the conveyor belt 46 moves between the four cylinders 331. When the output end of the cylinder 331 rises to the highest point, through the reverse output of the cylinder 331, the welded rubber plate moves downward and lands on the conveyor belt 46. Then, by driving the second driving motor 47, the conveyor belt 46 can roll between the rotating rod and the round rod 45. Due to the effect of the anti-slip sleeve at the corresponding position of the second pulling rope 49, the speed at which the second spring 481 restores the second pulling rope 49 to its original position is slow. Therefore, the four cylinders 331 can place the welded rubber plate on the conveyor belt 46, thereby removing the welded rubber plate from the inside of the frame body 1.
