A polyurethane sweeper with high wear resistance

Abstract

This utility model discloses a polyurethane sweeper with high wear resistance. The key technical points are that it belongs to the field of polyurethane sweepers and includes a support mechanism. A sweeping mechanism is movably connected to the inner side of the support mechanism. Protective mechanisms are fixedly connected to both ends of the sweeping mechanism. The protective mechanism includes a sliding groove located at the inner end of the support mechanism, and a buffer frame is slidably connected inside the sliding groove. By setting the buffer frame and buffer rod, when the polyurethane sweeper itself generates vibration or when there may be local jumping during belt operation, the buffer frame can cooperate with the buffer rod to buffer the movement. The buffer ring provides initial buffering for the buffer frame, and the damping component further buffers and suppresses the transmission. This prevents external forces from causing instantaneous strong impacts on the polyurethane blades during operation, reduces wear and fatigue caused by impacts or vibrations, and improves the durability and operational stability of the sweeper.

Description

Technical Field

[0001] This utility model relates to the field of polyurethane cleaners, and in particular to a polyurethane cleaner with high wear resistance. Background Technology

[0002] The main function of polyurethane cleaners is to remove residual materials from the surface of conveyor belts. Therefore, polyurethane cleaners are commonly used in conveyor belt systems and are a good helper for cleaning conveyor belt systems.

[0003] Chinese Patent Application No. CN202023099618.8 discloses a polyurethane sweeper that is easy to maintain. This design involves energizing and starting a motor. The motor's output power is reduced in speed by a reducer, causing the transmission shaft to drive a rotating gear. This gear moves, causing the fixed frame and the polyurethane sweeping blade to move away from the area below the conveyor belt. This facilitates maintenance of the polyurethane sweeping blade, improves operational portability, eliminates the need for downtime, reduces the impact on work efficiency, and enhances applicability. When the fixed frame moves, the guide block and the sliding groove on the fixed frame can easily limit the direction of movement and conveniently support the position of the fixed frame.

[0004] Existing polyurethane sweepers have certain drawbacks in use. First, during operation, both the conveyor belt and the sweeper itself generate impact and vibration forces. The lack of a protective structure in the sweeper leads to wear and fatigue caused by vibration, affecting its wear resistance and operational stability. Therefore, we propose a polyurethane sweeper with high wear resistance. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a polyurethane sweeper with high wear resistance. By setting up a buffer frame and a buffer rod, when the polyurethane sweeper is running, if the sweeper itself generates vibration or there is local jumping during the belt operation, the buffer frame can move to buffer the external force. The buffer frame for buffer adjustment slides outside the buffer rod. At this time, the buffer ring sleeved on the outside of the buffer rod provides initial buffering for the buffer frame. Then, the damping component buffers and suppresses the transmitted force. This allows the polyurethane sweeper to avoid instantaneous strong impact from external forces on the polyurethane blades during operation, preventing the blade head from breaking or deforming. It also reduces wear and fatigue caused by impact or vibration, improving the durability and working stability of the sweeper.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A polyurethane sweeper with high wear resistance includes a support mechanism, a sweeping mechanism is movably connected to the inner side of the support mechanism, and a protective mechanism is fixedly connected to both ends of the sweeping mechanism.

[0008] The protective mechanism includes a slide groove located at the inner end of the support mechanism. A buffer frame is slidably connected inside the slide groove. A buffer rod is slidably connected to the inner end of the buffer frame. A buffer ring is sleeved on the outer end of the buffer rod. A damping element that is symmetrically distributed is fixedly connected to the bottom end of the buffer frame.

[0009] The durability and operational stability of the sweeper can be improved by installing a buffer frame and buffer bar.

[0010] Furthermore, guide blocks are fixedly connected to both ends of the buffer frame, and buffer grooves are provided on both sides of the inner end of the slide.

[0011] By installing guide blocks, the buffer frame can be made more stable during the buffering and protection process, preventing it from falling off or shifting.

[0012] Furthermore, a mounting base is fixedly connected to the bottom end of the damping element.

[0013] By setting a mounting base, the damping component structure can be installed stably.

[0014] Furthermore, the support mechanism includes mounting brackets, and a protective bracket is fixedly connected to the upper end of each pair of mounting brackets.

[0015] By installing protective frames, a pair of protective frames can form a support structure on the outside of the protective mechanism, making the operation and use of the protective mechanism more stable.

[0016] Furthermore, a reinforcing frame is fixedly connected to the inner end of one pair of buffer frames, and an assembly frame that is symmetrically distributed is fixedly connected to the upper end of the reinforcing frame.

[0017] By installing the assembly frame, a support structure can be formed at both ends of the polyurethane blade and the external connection structure of the polyurethane blade, making the adjustment and use of the polyurethane blade more stable.

[0018] Furthermore, a polyurethane blade is rotatably connected to the inner side of the assembly frame, and the outer end of the polyurethane blade is provided with a wear-resistant coating.

[0019] The wear resistance of this polyurethane blade can be further improved by applying a wear-resistant coating.

[0020] Furthermore, the outer end of the polyurethane blade is movably connected to a tool holder, and the inner end of the tool holder is threadedly connected to multiple fixing components.

[0021] By installing a tool holder, the polyurethane blades can be installed stably, and the blades can also be easily disassembled and maintained.

[0022] Furthermore, a motor is fixedly connected to the outer end of one side of the assembly frame, a rotating shaft is fixedly connected to the transmission end of the motor, and a connecting shaft is fixedly connected to the outer end of the tool holder.

[0023] The installation of a rotating shaft further improves the wear resistance and ease of use of this polyurethane sweeper.

[0024] In summary, this utility model has the following beneficial effects:

[0025] 1. By setting up a buffer frame and a buffer rod, when the polyurethane sweeper is running, if the polyurethane sweeper itself generates vibration or there may be local jumping during the belt operation, the buffer frame can move to buffer with the external force. The buffer frame for buffer adjustment slides outside the buffer rod. At this time, the buffer ring sleeved outside the buffer rod provides initial buffering for the buffer frame. Then, the damping component buffers and suppresses the transmitted force. This allows the polyurethane sweeper to avoid instantaneous strong impact from external forces on the polyurethane blades during operation, preventing the blade head from breaking or deforming. It also reduces wear and fatigue caused by impact or vibration, improving the durability and working stability of the sweeper.

[0026] 2. By setting guide blocks, the guide blocks can move together with the buffer frame. The moving buffer frame and guide blocks slide inside the buffer groove, which makes the buffer frame more stable during the buffer protection process and prevents it from falling off or shifting.

[0027] 3. By setting a wear-resistant coating, which is composed of ceramic coating material, the surface hardness of the polyurethane blade can be enhanced, effectively reducing wear on the surface of the polyurethane blade, extending the service life of the polyurethane blade, and further improving the wear resistance of the polyurethane blade.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0036] Reference Figure 1-5 As shown, a polyurethane cleaner with high wear resistance is provided in a preferred embodiment of the present invention. It includes a support mechanism 1, a cleaning mechanism 2 is movably connected to the inner side of the support mechanism 1, and a protective mechanism 3 is fixedly connected to both ends of the cleaning mechanism 2.

[0037] The protective mechanism 3 includes a slide 301, which is located at the inner end of the support mechanism 1. A buffer frame 302 is slidably connected inside the slide 301. A buffer rod 303 is slidably connected to the inner end of the buffer frame 302. A buffer ring 304 is sleeved on the outer end of the buffer rod 303. A damping element 305 is fixedly connected to the bottom end of the buffer frame 302 in a symmetrical arrangement.

[0038] Reference Figure 3-5 As shown, further, guide blocks 306 are fixedly connected to both ends of the buffer frame 302, and buffer grooves 307 are provided on both sides of the inner end of the slide groove 301.

[0039] Reference Figure 4 As shown, the bottom end of the damping element 305 is further fixedly connected to a mounting base 308.

[0040] When the polyurethane cleaner itself generates vibration or there may be local jumping during the belt operation, the buffer frame 302 can move and buffer with the external force. The buffer frame 302, which is adjusted for buffering, slides outside the buffer rod 303. The guide block 306 can move together with the buffer frame 302. The moving buffer frame 302 and guide block 306 slide inside the buffer groove 307, which makes the buffer frame 302 more stable during the buffering protection process and prevents it from falling off or shifting. At this time, the buffer ring 304 sleeved outside the buffer rod 303 provides initial buffering for the buffer frame 302. Then, the damping element 305 buffers and suppresses the transmitted force. The mounting base 308 can install one end of the damping element 305 into the inner end of the slide groove 301 opened in the protective frame 102, so that the damping element 305 is structurally stable. This prevents the external force from causing a sudden strong impact on the polyurethane blade 201 when the polyurethane cleaner is running, prevents the blade head from breaking or deforming, and reduces wear and fatigue caused by impact or vibration.

[0041] Reference Figure 1 As shown, the support mechanism 1 further includes a mounting frame 101, and a protective frame 102 is fixedly connected to the upper end of each pair of mounting frames 101.

[0042] Reference Figure 1-2 As shown, further, a reinforcing frame 103 is fixedly connected to the inner end of a pair of buffer frames 302, and an assembly frame 104 that is symmetrically distributed is fixedly connected to the upper end of the reinforcing frame 103.

[0043] By installing a pair of protective frames 102, a support structure can be formed on the outside of the protective mechanism 3. The assembly frame 104 can form a support structure at both ends of the polyurethane blade 201 and the external connection structure of the polyurethane blade 201, making the adjustment and use of the polyurethane blade 201 more stable.

[0044] Reference Figure 1-2 As shown, a polyurethane blade 201 is rotatably connected to the inner side of the assembly frame 104, and a wear-resistant coating 202 is provided on the outer end of the polyurethane blade 201.

[0045] Reference Figure 2 As shown, the outer end of the polyurethane blade 201 is movably connected to a tool holder 203, and the inner end of the tool holder 203 is threadedly connected to a plurality of fasteners 204.

[0046] Reference Figure 2 As shown, a motor 205 is fixedly connected to the outer end of one side of the assembly frame 104, a rotating shaft 206 is fixedly connected to the transmission end of the motor 205, and a connecting shaft 207 is fixedly connected to the outer end of the tool holder 203.

[0047] By installing a wear-resistant coating 202 composed of ceramic coating material, the surface hardness of the polyurethane blade 201 can be enhanced, effectively reducing wear on the surface of the polyurethane blade 201 and extending its service life. The blade holder 203 can form a support structure at the outer end of the polyurethane blade 201, and with the help of multiple fasteners 204, the polyurethane blade 201 can be stably installed with the blade holder 203. When the polyurethane blade 201 needs to be disassembled, simply removing the fasteners 204 can stabilize the installation of the polyurethane blade 201 and facilitate disassembly and maintenance. The rotating shaft 206 can be rotated and adjusted when the motor 205 is started. The rotating shaft 206 drives the connected blade holder 203 and connecting shaft 207 to rotate simultaneously, allowing the angle of the polyurethane blade 201 to be easily adjusted. This allows the contact angle between the sweeper head and the belt of the cleaning equipment to be adjusted according to the degree of wear, reducing scraping force, improving wear resistance, and further enhancing the wear resistance and ease of use of the polyurethane sweeper.

[0048] Specific implementation process: When using this cleaner, first start the motor 205 according to the usage requirements. The rotating shaft 206 can be rotated and adjusted under the starting of the motor 205. The rotating shaft 206 drives the connected blade holder 203 and the connecting shaft 207 to rotate simultaneously, which allows the polyurethane blade 201 to be easily adjusted in angle. This allows the contact angle between the sweeper head and the belt of the cleaning device to be adjusted according to the degree of wear, reducing the scraping force. When the polyurethane blade 201 is in use, the wear-resistant coating 202 is composed of ceramic coating material, which can enhance the surface hardness of the polyurethane blade 201, effectively reduce the wear of the polyurethane blade 201 surface, and extend the service life of the polyurethane blade 201.

[0049] When the polyurethane cleaner itself generates vibration or there may be local jumping during the belt operation, the buffer frame 302 can move to buffer the external force. The buffer frame 302 for buffer adjustment slides outside the buffer rod 303, and the guide block 306 can move together with the buffer frame 302. The moving buffer frame 302 and the guide block 306 slide inside the buffer groove 307. At this time, the buffer ring 304 sleeved outside the buffer rod 303 provides initial buffering for the buffer frame 302, and the damping element 305 further buffers and suppresses the externally transmitted force. This prevents the polyurethane cleaner from causing a sudden strong impact on the polyurethane blade 201 when it is running, preventing the blade head from breaking or deforming, and reducing wear and fatigue caused by impact or vibration, making the operation of the polyurethane blade 201 more stable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
