Description

Technical Field

[0001] This utility model relates to the field of molding machine technology, specifically an auxiliary tooling for changing the roller of a molding machine guide carriage. Background Technology

[0002] Cord forming machines are specialized equipment used to process cord materials (such as rubber cords) into specific shapes and sizes. They can automatically complete the processes of cord conveying, positioning, and forming, and efficiently and accurately produce cord products that meet the requirements, such as tire cord layers and rubber conveyor belt cord layers, playing an important role in rubber products, tire manufacturing and other fields.

[0003] Regarding the aforementioned and existing related technologies: During the bonding of the inner liner, cord fabric, and sidewall in the molding machine, when the rubber material in the guide carriage runs out and needs to be replaced, the first operation is to remove the padding cloth on the guide carriage reel. There is a difficulty in removing the padding cloth here: the square steel of the guide carriage reel is too long, and there is a large amount of padding cloth wound on the square steel. The reel itself is also quite heavy. Due to this weight factor, one person cannot complete the removal of the guide carriage padding cloth and the replacement of the reel by themselves; two operators are required to complete the removal of the carriage padding cloth and the replacement of the reel, which leads to inconvenience in the replacement process. Therefore, to address the above problem, an auxiliary tooling for replacing the guide carriage reel of the molding machine is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: An auxiliary tooling for changing the roller of a forming machine guide trolley, comprising a machine body and a supporting device, wherein two chucks are fixedly connected to the surface of the machine body, and square steel is clamped onto the surface of the two chucks, with a pad covered on the surface of the square steel; the supporting device is located on one side of the machine body, and includes a carriage, which is located on one side of the machine body, with a hydraulic cylinder fixedly connected to the surface of the carriage, and two chains fixedly connected to the surface of the hydraulic cylinder, with a support plate fixedly connected to the surface of the two chains, the surface of the support plate slidingly connected to the inner surface of the machine body; activating the hydraulic cylinder drives the chains to move, the chains move the support plate, the support plate lifts the square steel and the pad, and the support plate moves on the inner surface of the carriage body; by setting up the carriage body, hydraulic cylinder, chains, and support plate, the pad can be moved.

[0006] Preferably, two guide discs are fixedly connected to the upper surface of the hydraulic cylinder. The guide discs are sleeved on the surface of the chain. When the hydraulic cylinder moves against the guide discs, the guide discs will move on the surface of the chain. By setting the guide discs, the position of the chain can be restricted.

[0007] Preferably, two switches are fixedly connected to the surface of the vehicle body. When it is necessary to start the hydraulic cylinder, stepping on the switch allows the switch to control the hydraulic cylinder. By setting the switches, the hydraulic cylinder can be operated conveniently, and the hands can be freed up at the same time.

[0008] Preferably, two handles are fixedly connected to the side wall of the vehicle body. When it is necessary to move the vehicle body, the handles are pulled to move the vehicle body. The handles make it easy to move the vehicle body.

[0009] Preferably, a baffle is fixedly connected to the side wall of the vehicle body. The baffle is fitted onto the surface of the hydraulic cylinder. When the staff walks around, the staff will be blocked by the baffle. By setting the baffle, the situation of staff accidentally touching the hydraulic cylinder can be reduced.

[0010] Preferably, the surface of the vehicle body is provided with a limiting device, which includes two support frames. The side walls of the two support frames are fixedly connected to the side walls of the vehicle body. A movable block is slidably connected to the surface of each of the two support frames. A limiting frame is fixedly connected to the side wall of the movable block. A connecting rod is fixedly connected to the bottom end of the two limiting frames. The connecting rod is located on the upper surface of the support plate. Pushing the limiting frame causes the limiting frame to move the connecting rod. The connecting rod fits against the support plate, and the limiting frame will fit over the surface of the pad. By setting the support frame, movable block, limiting frame and connecting rod, the position of the pad can be limited.

[0011] Preferably, the surface of the limiting frame is covered with a soft sleeve, and the surface of the movable block has two sliding holes. The inner walls of the two sliding holes of the movable block are slidably connected to the surface of the support frame. The movable block will slide on the surface of the support frame through the sliding holes. The sliding holes facilitate the movement of the movable block.

[0012] Preferably, fixed blocks are fixedly connected to both sides of the movable block, and insert rods are threadedly connected to the inner walls of the multiple fixed blocks and the two support frames. The insert rods are rotated to the inner walls of the multiple fixed blocks and the two support frames. By setting the insert rods and fixed blocks, the position of the movable block can be restricted.

[0013] The advantages of this utility model are:

[0014] 1. When performing replacement operations, this utility model involves pushing the handle to move the vehicle body. As the vehicle body moves, the support plate will fit against the surface of the square steel and pad. Then, the foot switch controls the hydraulic cylinder, which lifts the guide plate. As the guide plate moves, it moves on the chain surface, which in turn moves the support plate. The support plate slides on the inner surface of the vehicle body, lifting the square steel and pad. When the worker walks, they will be blocked by the guardrail. Pulling the handle will then move the vehicle body, which in turn moves the square steel and pad on the support plate. By setting up the entire device, the square steel and pad can be moved easily, reducing the risk of accidental slippage and injury during handling. It also reduces the cumbersome handling process for workers and saves their effort.

[0015] 2. In this invention, after the square steel and pad are placed on the surface of the support plate, the limiting frame is pushed to move the moving block. The moving block slides on the surface of the support frame through the sliding hole. When the limiting frame moves, it also moves the connecting rod and the soft sleeve. The limiting frame and the soft sleeve will be placed on the surface of the pad. The connecting rod is in contact with the support plate. When the moving block moves, it also moves the fixed block. After the fixed block moves to the appropriate position, the insertion rod is rotated to the inner wall of multiple fixed blocks and two support frames. By setting the entire device, the lateral position of the pad on the support plate can be restricted, thereby reducing the occurrence of safety accidents. Attached Figure Description

[0024] Please see Figure 1-5 As shown, an auxiliary tooling for changing the roller of a forming machine guide trolley includes a machine body 1 and a support device 5. Two chucks 2 are fixedly connected to the surface of the machine body 1, and square steel bars 3 are clamped onto the surfaces of the two chucks 2. A pad 4 is fitted onto the surface of the square steel bars 3. The support device 5 is located on one side of the machine body 1 and includes a carriage 51. The carriage 51 is located on one side of the machine body 1, and a hydraulic cylinder 52 is fixedly connected to the surface of the carriage 51. Two chains 53 are fixedly connected to the surface of the hydraulic cylinder 52. A support plate 54 is fixedly connected, and the surface of the support plate 54 is slidably connected to the inner surface of the machine body 1. During operation, the moving vehicle body 51 is moved to a suitable position. When the vehicle body 51 moves, the support plate 54 is inserted into the bottom end of the pad 4. Then, the hydraulic cylinder 52 is activated to drive the chain 53 to move. The chain 53 drives the support plate 54 to move, and the support plate 54 lifts the square steel 3 and the pad 4. The support plate 54 moves on the inner surface of the vehicle body 51. By setting the vehicle body 51, hydraulic cylinder 52, chain 53 and support plate 54, the pad 4 can be transported.

[0025] Two guide discs 55 are fixedly connected to the upper surface of the hydraulic cylinder 52. The guide discs 55 are sleeved on the surface of the chain 53. During operation, the guide discs 55 will move on the surface of the chain 53. By setting the guide discs 55, the position of the chain 53 can be restricted.

[0026] Two switches 56 are fixedly connected to the surface of the vehicle body 51. When working, stepping on the switch 56 allows the switch 56 to control the hydraulic cylinder 52. By setting the switch 56, the hydraulic cylinder 52 can be easily operated, and the hands can be freed up.

[0027] Two handles 57 are fixedly connected to the side wall of the vehicle body 51; during operation, pulling the handles 57 causes the vehicle body 51 to move, and the handles 57 facilitate the movement of the vehicle body 51.

[0028] A baffle 58 is fixedly connected to the side wall of the vehicle body 51, and the baffle 58 is fitted onto the surface of the hydraulic cylinder 52. During operation, the staff will be blocked by the baffle 58. By setting the baffle 58, the situation of staff accidentally touching the hydraulic cylinder 52 can be reduced.

[0029] The surface of the vehicle body 51 is provided with a limiting device 6, which includes two support frames 61. The side walls of the two support frames 61 are fixedly connected to the side walls of the vehicle body 51. The surfaces of the two support frames 61 are slidably connected with moving blocks 62. The side walls of the moving blocks 62 are fixedly connected with limiting frames 63. The bottom ends of the two limiting frames 63 are fixedly connected with connecting rods 64, which are located on the upper surface of the support plate 54. During operation, pushing the moving blocks 62 causes the limiting frames 63 to move, and the limiting frames 63 cause the connecting rods 64 to slide. The moving blocks 62 will slide on the surface of the support frames 61. After the pad 4 is placed on the upper surface of the support plate 54, pushing the limiting frames 63 causes the limiting frames 63 to move the connecting rods 64. The connecting rods 64 are in contact with the support plate 54, and the limiting frames 63 will be fitted onto the surface of the pad 4. By setting the support frames 61, moving blocks 62, limiting frames 63 and connecting rods 64, the position of the pad 4 can be limited.

[0030] The surface of the limiting frame 63 is covered with a soft sleeve 65, and the surface of the moving block 62 is provided with two sliding holes 68. The inner walls of the two sliding holes 68 of the moving block 62 are slidably connected to the surface of the support frame 61. During operation, the limiting frame 63 will drive the soft sleeve 65 to move. When the moving block 62 moves, the moving block 62 will slide on the surface of the support frame 61 through the sliding holes 68. The sliding holes 68 make it easy for the moving block 62 to move.

[0031] Both sides of the movable block 62 are fixedly connected to fixed blocks 66, and the inner walls of the multiple fixed blocks 66 and the two support frames 61 are threadedly connected to insert rods 67. During operation, the movable block 62 drives the fixed blocks 66 to slide, and then the insert rods 67 are rotated to the inner walls of the multiple fixed blocks 66 and the two support frames 61. By setting the insert rods 67 and fixed blocks 66, the position of the movable block 62 can be restricted.

[0032] Working principle: During replacement work, pushing the handle 57 moves the vehicle body 51. As the vehicle body 51 moves, the support plate 54 will conform to the surface of the square steel 3 and the pad 4. Then, the foot switch 56 controls the hydraulic cylinder 52, which lifts the guide plate 55. As the guide plate 55 moves, it moves on the surface of the chain 53, which in turn moves the support plate 54. The support plate 54 slides on the inner surface of the vehicle body 51, lifting the square steel 3 and the pad 4. When the worker walks, they will be blocked by the stop 58. Pulling the handle 57 moves the vehicle body 51, which in turn moves the square steel 3 and the pad 4 on the support plate 54. By setting up the entire device, the square steel 3 and the pad 4 can be moved easily, reducing the risk of accidental detachment during handling. This device reduces the risk of hand injuries and the hassle of handling the pad, saving workers' effort. After the square steel 3 and the pad 4 are placed on the surface of the support plate 54, the limit frame 63 is pushed to move the moving block 62. The moving block 62 slides on the surface of the support frame 61 through the sliding hole 68. When the limit frame 63 moves, it also moves the connecting rod 64 and the soft sleeve 65. The limit frame 63 and the soft sleeve 65 will be placed on the surface of the pad 4. The connecting rod 64 is in contact with the support plate 54. When the moving block 62 moves, it also moves the fixed block 66. After the fixed block 66 moves to the appropriate position, the insertion rod 67 is rotated to the inner wall of the multiple fixed blocks 66 and the two support frames 61. By setting up the entire device, the lateral position of the pad 4 on the support plate 54 can be restricted, thereby reducing the possibility of safety accidents.
