Description

Technical Field

[0001] This utility model belongs to the technical field of plastic cleaning equipment, and in particular relates to a roller support for a plastic friction cleaning machine with shock absorption and noise reduction. Background Technology

[0002] With the booming development of the plastic recycling industry, the requirements for plastic cleaning are becoming increasingly stringent. As a key piece of equipment in the plastic cleaning process, the performance of the plastic friction cleaning machine directly affects the cleaning effect and production efficiency. The roller support, as the core supporting component of the plastic friction cleaning machine, plays a decisive role in the stable operation of the equipment. Therefore, the roller support provides stable and reliable support for the entire device.

[0003] However, the existing friction cleaning machine drum support is not convenient for buffering the vibration generated by the drum during use. The vibration of the drum will be directly transmitted to the support and the entire equipment, resulting in increased overall vibration of the equipment, which may cause obvious shaking and even affect the normal operation of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a plastic friction cleaning machine drum support with shock absorption and noise reduction. By setting a shock absorption mechanism, the existing friction cleaning machine drum support is not convenient to buffer the vibration generated by the drum during use. The vibration of the drum is directly transmitted to the support and the entire equipment, which leads to increased overall vibration of the equipment, which may cause obvious shaking and even affect the normal operation of the equipment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a plastic friction cleaning machine drum support with shock absorption and noise reduction, including a support frame, on which a plurality of shock absorption mechanisms and buffer mechanisms are provided;

[0007] The shock absorption mechanism includes a rectangular shell fixedly connected to the inner wall of the support frame. A rectangular plate is slidably connected to the inner wall of the rectangular shell. Two fixing blocks are fixedly connected to the top of the rectangular plate. A damper is fixedly connected to the side of the two fixing blocks that are close to each other. A spring is sleeved on the outer wall of each of the two dampers. The side of the two springs that are far apart from each other is fixedly connected to the two fixing blocks respectively. A rectangular block is fixedly connected to the side of the two dampers that are close to each other. The side of the two rectangular blocks that are far apart from each other is fixedly connected to the two springs respectively. The buffer mechanism includes two support plates disposed below the support frame.

[0008] Furthermore, each of the two rectangular blocks has a hinged rod at its top, and the top of each of the two hinged rods is hinged to the rectangular shell. The bottom of the rectangular plate is fixedly connected to two support blocks, and a rotating shaft runs through the two support blocks. The rotating shaft is rotatably connected to the two support blocks, and a roller is fixedly connected to the outer wall of the rotating shaft.

[0009] Furthermore, a base plate is provided below the support frame, and a roller is provided inside the support frame. The outer wall of the roller is in contact with the roller wheel. The top of the base plate is fixedly connected to two support plates, and two dampers are fixedly connected to the top of each of the two support plates.

[0010] Furthermore, each of the dampers 2 has a spring 2 fitted on its outer wall, the bottom of each spring 2 is fixedly connected to two support plates, the top of each support plate is fixedly connected to a sliding rod, the top of each sliding rod extends into the support frame, and the two sliding rods are slidably connected to the support frame.

[0011] Furthermore, the outer wall of the support frame is fixedly connected to two connecting blocks, the two sliding rods are slidably connected to the two connecting blocks respectively, the tops of the several springs are fixedly connected to the two connecting blocks respectively, and the tops of the two sliding rods are fixedly connected to limit blocks.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting up a shock absorption mechanism, when the drum rotates and vibrates, assuming the vibration is upward, we analyze the upper shock absorption mechanism. The roller will be squeezed by the drum, and the force will be transmitted to the rectangular plate through the rotating shaft and support block, causing the rectangular plate to slide upward inside the rectangular shell. This will cause the two hinge rods to rotate around their common hinge axis, thereby driving the two rectangular blocks away from each other. Then, the two rectangular blocks will squeeze the two dampers and springs respectively, causing the two dampers and springs to contract. The other upper shock absorption mechanisms work in the same way, while the lower shock absorption mechanism is the opposite. The damper and spring will be stretched to absorb the vibration force. This allows the plastic friction cleaning machine to absorb and buffer the vibration of the drum caused by the friction and tumbling of the internal materials during operation, thereby avoiding the displacement and loosening of the equipment due to vibration. At the same time, it reduces the harsh noise caused by friction and improves the noise level of the working environment.

[0014] 2. By setting up a buffer mechanism, when the support frame vibrates, the support frame will drive the two connecting blocks on it to slide up and down under the limit of the slide rod, thereby continuously squeezing the second damper and the second spring below. When squeezed, the second damper and the second spring will contract, thereby absorbing part of the impact force of the vibration. Then the second damper and the second spring will reset, driving the support frame to reset. This process is repeated to achieve the purpose of vibration reduction and noise reduction. It can absorb and dissipate the vibration of the support caused by the rotation of the roller and the movement of the internal materials, thereby further preventing the overall instability or even displacement of the equipment caused by vibration, and reducing the noise generated by collision and friction.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 As shown, this utility model is a shock-absorbing and noise-reducing plastic friction cleaning machine drum support, including a support frame 1. The support frame 1 is equipped with several shock-absorbing mechanisms 2 and buffer mechanisms 3. Each shock-absorbing mechanism 2 includes a rectangular shell 211 fixedly connected to the inner wall of the support frame 1. A rectangular plate 212 is slidably connected to the inner wall of the rectangular shell 211. Two fixing blocks 213 are fixedly connected to the top of the rectangular plate 212. A damper 214 is fixedly connected to the side of each fixing block 213 that is close to each other. A spring 215 is fitted onto the outer wall of each damper 214. The side of each spring 215 that is far from each other is fixedly connected to the two fixing blocks 213. A rectangular block 216 is fixedly connected to the side of each damper 214 that is close to each other. The side of each rectangular block 216 that is far from each other is fixedly connected to the two springs 215. Each rectangular block 216 has a hinged rod 217 at its top, and the top of each of the two hinge rods 217 is hinged to the rectangular shell 211. The bottom of the rectangular plate 212 is fixedly connected to two support blocks 218, and a rotating shaft 219 passes through the two support blocks 218. The rotating shaft 219 is rotatably connected to the two support blocks 218. A roller 2110 is fixedly connected to the outer wall of the rotating shaft 219. A base plate 111 is set below the support frame 1. A roller 112 is set inside the support frame 1. The outer wall of the roller 112 is in contact with the roller 2110. By setting a shock absorption mechanism 2, the vibration of the roller caused by the friction and tumbling of the internal material can be absorbed and buffered when the plastic friction cleaning machine is working, thereby avoiding the displacement and loosening of the equipment due to vibration. At the same time, it reduces the harsh noise caused by friction and improves the noise level of the working environment.

[0026] The buffer mechanism 3 includes two support plates 311 disposed below the support frame 1. The top of the base plate 111 is fixedly connected to the two support plates 311. Two dampers 312 are fixedly connected to the top of each of the two support plates 311. Springs 313 are fitted on the outer walls of several dampers 312. The bottoms of several springs 313 are fixedly connected to the two support plates 311 respectively. Slide rods 314 are fixedly connected to the top of each of the two support plates 311. The tops of the two slide rods 314 extend into the support frame 1. The two slide rods 314 are connected to the support... The frame 1 is slidably connected, and two connecting blocks 315 are fixedly connected to the outer wall of the support frame 1. Two sliding rods 314 are slidably connected to the two connecting blocks 315 respectively. The tops of several springs 313 are fixedly connected to the two connecting blocks 315 respectively. The tops of the two sliding rods 314 are fixedly connected to limit blocks 316. By setting the buffer mechanism 3, the vibration of the support caused by the rotation of the roller and the movement of the internal material can be absorbed and dissipated, thereby further preventing the overall instability or even displacement of the equipment caused by vibration, and reducing the noise generated by collision and friction.

[0027] A specific application of this embodiment is as follows: During use, when the roller 112 rotates and vibrates (assuming it is an upward vibration), analyzing the damping mechanism 2 located above, the roller 2110 will be squeezed by the roller 112, thereby transmitting force to the rectangular plate 212 through the rotating shaft 219 and the support block 218, causing the rectangular plate 212 to slide upward within the rectangular shell 211. This causes the two hinge rods 217 to be stressed and rotate around their common hinge axis, thereby driving the two rectangular blocks 216 away from each other. Consequently, the two rectangular blocks 216 respectively squeeze the two dampers 214 and the spring 215, causing the two dampers 214 and the spring 215 to... 215 retracts, and the other damping mechanisms 2 located on the upper side work in the same way. The damping mechanism 2 located on the lower side works in the opposite way. The damper 214 pulls the spring 215 to absorb the force of vibration. When the support frame 1 vibrates, the support frame 1 will drive the two connecting blocks 315 on it to slide up and down under the limit of the slide rod 314, thereby continuously squeezing the damper 312 and spring 313 below. The damper 312 and spring 313 will retract when squeezed, thereby absorbing part of the impact force of vibration. Then the damper 312 and spring 313 will reset and drive the support frame 1 to reset. This process is repeated to achieve the purpose of vibration reduction and noise reduction.
