Description

Technical Field

[0001] This utility model relates to the technical field of roller changing devices, and in particular to an automatic roller changing device for pretreatment extrusion rollers. Background Technology

[0002] A squeeze roller is a device used in the aluminum foil processing process to squeeze raw materials passing through a water tank. When using a squeeze roller, the raw materials for processing aluminum foil are passed through the inside of the water tank, and then squeezed by the squeeze roller, so that the raw materials can effectively absorb water into their interior, thus facilitating the cleaning of the raw materials.

[0003] In their daily work, the inventors discovered that the roller changing device still has at least the following problems: When using the squeeze roller, the raw material for processing aluminum foil paper passes through the inside of the water tank, and then the squeeze roller squeezes the raw material so that the raw material can effectively absorb water into its interior, thus facilitating the cleaning of the raw material. When using the roller changing device, it is generally necessary to manually disassemble the squeeze roller body from the support frame by turning the bolts, because the squeeze roller body is connected by multiple bolts, which makes it relatively troublesome to replace the squeeze roller body. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic roller changing device for pretreatment extrusion rollers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic roller changing device for pretreatment squeezing rollers, comprising a support frame, wherein squeezing roller bodies are uniformly arranged inside the support frame, a connecting device is provided on one side of the support frame, and a squeezing device is provided at the bottom of the squeezing roller bodies. The connecting device includes a locking strip, a connecting groove is provided on one side of the support frame, the squeezing roller bodies are disposed inside the connecting groove, a sliding groove is provided on one side of the support frame, the locking strip is slidably connected to the inner wall of the sliding groove, and a first spring is fixedly connected to the top of the locking strip, the top of the first spring being fixedly connected to the top of the sliding groove.

[0006] The effect achieved by the above components is as follows: when using the connecting device, the first spring is compressed, which causes the locking strip to slide upward inside the groove, thereby moving the locking strip away from the connecting groove and exposing the connecting groove. Since the bottom of the connecting groove is a downward sloping surface, the squeezing roller body can be kept away from the inside of the connecting groove, thus enabling automatic roller changing.

[0007] Preferably, a first motor is fixedly connected to the side of the support frame away from the squeezing roller body, a first collecting roller is fixedly connected to the output end of the first motor, a first connecting rope is fixedly connected to the surface of the first collecting roller, the first connecting rope is slidably inserted through the top of the chute, and the end of the first connecting rope away from the first collecting roller is fixedly connected to the top of the locking strip.

[0008] The effect achieved by the above components is as follows: starting the first motor drives the first collecting roller to rotate, which can effectively wrap the first connecting rope around the surface of the first collecting roller, and effectively control the positioning strip to move upward inside the chute.

[0009] Preferably, a connecting frame is slidably inserted into the side of the support frame near the body of the squeezing roller, and a limiting groove is formed on one side of the connecting frame, the limiting groove being disposed on one side of the connecting groove.

[0010] The effect achieved by the above components is that when the squeezing roller body is far away from the connecting groove, it falls directly into the inside of the limiting groove, and then the connecting frame is controlled to move upward on one side of the support frame, which makes it easier to drive the squeezing roller body away from the connecting groove.

[0011] Preferably, the bottom of the connecting groove is provided with a groove, the inner wall of the groove is fixedly connected to a limiting rod, the surface of the limiting rod is rotatably fitted with a rotating plate, the top inner wall of the connecting groove is fixedly connected to a limiting block on the side away from the connecting frame, the bottom of the inner wall of the groove is fixedly connected to an elastic rope, and the end of the elastic rope away from the groove is fixedly connected to the end of the rotating plate away from the limiting rod.

[0012] The effect achieved by the above components is as follows: when the squeezing roller body enters the limiting groove, the squeezing roller body squeezes the rotating plate, thereby causing the squeezing roller body to enter the limiting groove. Then, through the pulling action of the elastic rope, the rotating plate returns to its original position.

[0013] Preferably, a second motor is fixedly connected to the side of the support frame near the body of the squeezing roller, a second collecting roller is fixedly connected to the output end of the second motor, a second connecting rope is fixedly connected to the surface of the second collecting roller, and the end of the second connecting rope away from the second collecting roller is fixedly connected to the top of the connecting frame.

[0014] The effect achieved by the above components is as follows: starting the second motor drives the second collecting roller to rotate, which can make the second connecting rope wrap around the surface of the second collecting roller, thus effectively controlling the connecting frame to move upward on one side of the support frame.

[0015] Preferably, the extrusion device includes an extrusion plate, a positioning groove is provided on one side of the support frame, the inner wall of the positioning groove is slidably connected to the extrusion plate, a rectangular plate is provided on the top of the extrusion plate, and a rubber strip is fixedly connected to the top of the rectangular plate.

[0016] The effect achieved by the above components is that when the extrusion device is used, the rubber strip is set at the bottom of the squeezing roller body. In this way, when it is necessary to clean the squeezing roller body below, the rubber strip can effectively clean the surface of the squeezing roller body and prevent garbage from accumulating on the surface of the squeezing roller body.

[0017] Preferably, a damping rod is uniformly fixedly connected to the top of the extrusion plate, the top of the damping rod is fixedly connected to the bottom of the rectangular plate, a second spring is sleeved on the surface of the damping rod, the bottom of the second spring is fixedly connected to the top of the extrusion plate, and the end of the second spring near the damping rod is fixedly connected to the bottom of the rectangular plate.

[0018] The effect achieved by the above components is that the rubber strip is squeezed towards the body of the squeeze roller by the second spring, so that the rubber strip can be squeezed well at the bottom of the body of the squeeze roller.

[0019] Preferably, positioning plates are fixedly connected to both sides of the support frame, and a threaded rod is rotatably inserted through the positioning plate. The threaded rod is threaded through the top of the extrusion plate, and a locking rod is rotatably inserted through the top of the other positioning plate. The locking rod is slidably inserted through the top of the extrusion plate.

[0020] The effect achieved by the above components is that the screw rod can be manually controlled to rotate, and under the restriction of the locking rod, the extrusion plate can be moved well inside the positioning groove, so that the extrusion plate can get close to the body of the squeezing roller. This, to a certain extent, avoids the extrusion plate not being squeezed well due to the change in the elasticity of the second spring after long-term use.

[0021] In this invention, by setting a connecting device, when the connecting device is used, the first spring is compressed, which causes the locking strip to slide upward inside the groove, thereby moving the locking strip away from the connecting groove and exposing the connecting groove. Since the bottom of the connecting groove is a downward sloping surface, the squeezing roller body can be kept away from the inside of the connecting groove, thus enabling automatic roller changing.

[0027] Example 1, such as Figure 1-4 As shown, the pretreatment squeezing roller automatic roller changing device has a support frame 1 in which squeezing roller bodies 2 are evenly arranged. A connecting device 3 is provided on one side of the support frame 1, and a squeezing device 4 is provided at the bottom of the squeezing roller body 2. When using the squeezing roller, the raw material for processing aluminum foil paper passes through the inside of the water tank, and then the raw material is squeezed by the squeezing roller, so that the raw material can absorb water into the raw material, which facilitates the cleaning of the raw material.

[0028] Reference Figure 2 and Figure 3The connecting device 3 includes a locking strip 303. A connecting groove 301 is provided on one side of the support frame 1. The squeezing roller body 2 is disposed inside the connecting groove 301. A sliding groove 302 is provided on one side of the support frame 1. The locking strip 303 is slidably connected to the inner wall of the sliding groove 302. A first spring 304 is fixedly connected to the top of the locking strip 303. The top of the first spring 304 is fixedly connected to the top of the sliding groove 302. When using the connecting device 3, the first spring 304 is compressed, causing the locking strip 303 to slide upwards inside the sliding groove 302. This causes the locking strip 303 to move away from the connecting groove 301, exposing the connecting groove 301. Because the bottom of the connecting groove 301 is a downward sloping surface, this allows the squeezing roller body 2 to... Body 2 is well away from the interior of the connecting groove 301, thus enabling automatic roller changing. A first motor 306 is fixedly connected to the side of the support frame 1 away from the squeezing roller body 2. A first collecting roller 307 is fixedly connected to the output end of the first motor 306. A first connecting rope 305 is fixedly connected to the surface of the first collecting roller 307. The first connecting rope 305 slides through and is inserted into the top of the chute 302. The end of the first connecting rope 305 away from the first collecting roller 307 is fixedly connected to the top of the locking strip 303. When the first motor 306 is started, it drives the first collecting roller 307 to rotate, thus effectively winding the first connecting rope 305 around the surface of the first collecting roller 307, thereby effectively controlling the locking strip. 303 moves upward inside the chute 302. A connecting frame 308 is slidably inserted into the side of the support frame 1 near the squeezing roller body 2. A limiting groove 309 is opened on one side of the connecting frame 308. The limiting groove 309 is located on one side of the connecting groove 301. When the squeezing roller body 2 moves away from the connecting groove 301, it falls directly into the limiting groove 309. Then, the connecting frame 308 is controlled to move upward on one side of the support frame 1. This facilitates the squeezing roller body 2 moving away from the side of the connecting groove 301. A groove 310 is opened at the bottom of the connecting groove 301. A limiting rod 311 is fixedly connected to the inner wall of the groove 310. A rotating plate 312 is rotatably sleeved on the surface of the limiting rod 311. The inner wall of the top of the connecting groove 301 is fixed on the side away from the connecting frame 308. A limit block 313 is connected to the bottom of the inner wall of the groove 310, and an elastic rope 314 is fixedly connected to it. The end of the elastic rope 314 away from the groove 310 is fixedly connected to the end of the rotating plate 312 away from the limit rod 311. When the squeezing roller body 2 enters the limiting groove 309, the squeezing roller body 2 squeezes the rotating plate 312, thereby causing the squeezing roller body 2 to enter the limiting groove 309. Then, through the pulling action of the elastic rope 314, the rotating plate 312 returns to its original position. A second motor 315 is fixedly connected to the side of the support frame 1 near the squeezing roller body 2. A second collecting roller 316 is fixedly connected to the output end of the second motor 315. A second connecting rope 317 is fixedly connected to the surface of the second collecting roller 316.The end of the second connecting rope 317 furthest from the second collecting roller 316 is fixedly connected to the top of the connecting frame 308. Starting the second motor 315 drives the second collecting roller 316 to rotate. This allows the second connecting rope 317 to wrap around the surface of the second collecting roller 316, thus effectively controlling the upward movement of the connecting frame 308 on one side of the support frame 1.

[0029] Reference Figure 4 The extrusion device 4 includes an extrusion plate 402. A positioning groove 401 is provided on one side of the support frame 1. The inner wall of the positioning groove 401 is slidably connected to the extrusion plate 402. A rectangular plate 405 is fixedly connected to the top of the extrusion plate 402. A rubber strip 406 is fixedly connected to the top of the rectangular plate 405. When using the extrusion device 4, the rubber strip 406 is set at the bottom of the squeezing roller body 2. In this way, when it is necessary to clean the squeezing roller body 2 below, the rubber strip 406 can effectively clean the surface of the squeezing roller body 2 and prevent garbage from accumulating on the surface of the squeezing roller body 2. A damping rod 403 is uniformly fixedly connected to the top of the extrusion plate 402. The top of the damping rod 403 is fixedly connected to the bottom of the rectangular plate 405. A second spring 404 is sleeved on the surface of the damping rod 403. The bottom of the second spring 404 is fixedly connected to the top of the extrusion plate 402. The end of the second spring 404 near the damping rod 403 is fixedly connected to the rectangular plate. The bottom of 405 is fixedly connected, and the rubber strip 406 is squeezed towards the squeezing roller body 2 by the second spring 404. This allows the rubber strip 406 to be squeezed well at the bottom of the squeezing roller body 2. Positioning plates 407 are fixedly connected to both sides of the support frame 1. The positioning plate 407 is rotatably inserted with a threaded rod 409, which is threaded through and inserted into the top of the squeezing plate 402. The top of the other positioning plate 407 is rotatably inserted with a locking rod 408, which is slidably inserted into the top of the squeezing plate 402. The threaded rod 409 is manually rotated. Under the restriction of the locking rod 408, the squeezing plate 402 can be moved well inside the positioning groove 401, so that the squeezing plate 402 can be close to the squeezing roller body 2. This, to a certain extent, avoids the squeezing plate 402 from being unable to be squeezed well due to the change in the elasticity of the second spring 404 after long-term use.

[0030] Working principle: When using the squeeze roller, the raw material for processing aluminum foil passes through the inside of the water tank, and is then squeezed by the squeeze roller, allowing the material to effectively absorb water, thus facilitating cleaning. When using the connecting device 3, the first motor 306 is started, driving the first collecting roller 307 to rotate. This effectively winds the first connecting rope 305 around the surface of the first collecting roller 307, thus controlling the upward movement of the locking strip 303 inside the chute 302, thereby moving the locking strip 303 away from the water tank. The connecting groove 301 is exposed because its bottom is a downward sloping surface. This allows the squeezing roller body 2 to move away from the inside of the connecting groove 301. When the squeezing roller body 2 moves away from the connecting groove 301, it falls directly into the limiting groove 309. As the squeezing roller body 2 enters the limiting groove 309, it squeezes the rotating plate 312, thus causing the squeezing roller body 2 to enter the limiting groove 309. Then, through the pulling action of the elastic rope 314, the rotating plate 312... Returning to the original position, the second motor 315 is started to drive the second collecting roller 316 to rotate. This allows the second connecting rope 317 to wrap around the surface of the second collecting roller 316, which in turn allows the connecting frame 308 to move upward on one side of the support frame 1. This facilitates moving the squeezing roller body 2 away from the connecting groove 301, thus enabling automatic roller changing. When using the squeezing device 4, the second spring 404 squeezes the rubber strip 406 towards the squeezing roller body 2, ensuring that the rubber strip 406 is effectively pressed against the bottom of the squeezing roller body 2. This allows the rubber strip 406 to effectively clean the surface of the squeezing roller body 2 when cleaning is required, preventing the accumulation of debris. The manually controlled threaded rod 409 rotates, and under the restriction of the locking rod 408, it effectively moves the squeezing plate 402 within the positioning groove 401, allowing the squeezing plate 402 to approach the squeezing roller body 2. This, to some extent, prevents the second spring 404 from losing its elasticity and failing to effectively squeeze the squeezing plate 402 due to long-term use.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
