Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane elastomer processing, in particular to polyurethane elastomer surface coating equipment. Background Art

[0002] Polyurethane elastomer is a special polymer synthetic material with adjustable hardness. Due to its structural characteristics, its friction coefficient is much higher than that of materials such as polytetrafluoroethylene and ultra-high molecular weight polyethylene. When polyurethane elastomer is used as a transmission component or sealing component, there are problems such as high heat generation and rapid wear due to excessive friction coefficient, which leads to premature destruction of the polyurethane material and loss of function, making it impossible to fully demonstrate the excellent wear resistance of the polyurethane elastomer.

[0003] In order to reduce the friction coefficient of the polyurethane elastomer, the polyurethane elastomer can be immersed in a surface treatment agent and then further treated by heating and drying and other processes, so as to achieve the effect of reducing the friction coefficient of the polyurethane elastomer. However, when the polyurethane elastomer is treated with a surface treatment agent, the existing method is to adopt a dipping method, that is, to immerse the entire polyurethane elastomer in the surface treatment agent. When the polyurethane elastomer is taken out of the surface treatment agent, it is necessary to wait for a certain period of time so that the flowable surface treatment agent adhering to the surface of the polyurethane elastomer can flow back into the processing box.

[0004] The existing multi-layer mesh box is adopted, and multiple polyurethane elastomers are placed on each layer. When it is taken out from the surface treatment agent, the surface treatment agent on the upper side will continuously drip onto the polyurethane elastomer below, resulting in a significant increase in the time waiting for the surface treatment agent to flow back into the processing box. If only a single-layer mesh box is adopted, although the time for the surface treatment agent to flow back into the processing box is shorter, the number of polyurethane elastomers processed becomes lower, affecting the processing efficiency and making it difficult to meet the use requirements. Utility Model Content

[0005] The purpose of the utility model is to provide a polyurethane elastomer surface coating device, aiming to solve the problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: the polyurethane elastomer surface coating equipment includes a box body, the inner bottom of the box body is used to store the surface treatment agent, the upper end of the box body is slidably connected with a slide plate, the outer surface of the box body is provided with a first hydraulic telescopic rod for driving the slide plate to slide along the upper end of the box body, and also includes a placement box, the placement box has a plurality of block nets, the outer side of the block nets is provided with a reinforcing ring plate, and the adjacent ring plates are connected by a fixed column, and the lower surface of the slide plate is symmetrically provided with a second hydraulic telescopic rod, and the output end of the hydraulic telescopic rod is fixedly connected to the ring plate located at the bottom, and a material guide plate is evenly provided on one side of the interior of the box body, and the material guide plate can enter between two adjacent block nets, and an operation window is opened on one side of the upper part of the box body.

[0007] Preferably, the material guide plate is arranged obliquely, and the lower end of the material guide plate is inclined toward the inner bottom of the box body.

[0008] Preferably, a through groove is opened on one side of the ring plate, a mounting groove is arranged inside the through groove, a scraper is slidably connected inside the mounting groove, a spring is arranged inside the mounting groove for pushing the scraper to move outside the mounting groove, and a material guide groove is arranged at the lower end of the guide plate.

[0010] Preferably, a material storage box is provided on one side of the box body, and a liquid pump is provided inside the material storage box.

[0011] The beneficial effects of the utility model are:

[0012] The device can, through the material guide plates that are set up, enable the surface treatment agent dripping from the surface of the polyurethane elastomer on the screens of different heights to drip onto the material guide plates that are below each screen and closest to it. That is, the surface treatment agent on the polyurethane elastomer will not drip onto the polyurethane elastomer on the screen below. The dripping rate of the surface treatment agent on the polyurethane elastomer on the screens at each height is roughly the same, thereby shortening the time for the surface treatment agent to flow back into the box, ensuring appropriate treatment efficiency and good use effect. At the same time, the scraper and material guide trough that are set up can improve the efficiency of the treatment agent on the upper surface of the material guide plate to flow back into the box.

DETAILED DESCRIPTION

[0020] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0021] like Figure 1-6 As shown, a polyurethane elastomer surface coating device includes a box body 1, the inner bottom of the box body 1 is used to store the surface treatment agent, the upper end of the box body 1 is slidably connected with a slide plate 2, the outer surface of the box body 1 is provided with a first hydraulic telescopic rod 3 for driving the slide plate 2 to slide along the upper end of the box body 1, and also includes a placement box, the placement box has a plurality of block nets 4, the outer side of the block net 4 is provided with a reinforcing ring plate 5, adjacent ring plates 5 are connected by fixed columns 6, the lower surface of the slide plate 2 is symmetrically provided with a second hydraulic telescopic rod 7, the output end of the hydraulic telescopic rod is fixedly connected to the ring plate 5 located at the bottom, and a material guide plate 8 is evenly provided on one side of the interior of the box body 1, and the material guide plate 8 can enter between two adjacent block nets 4, and an operation window is opened on one side of the upper part of the box body 1.

[0022] like Figure 1As shown, through holes are provided at both ends of the slide plate 2, and guide rods are respectively provided on both sides of the upper end of the box body 1. The through holes on the slide plate 2 are slidably connected with the guide rods. Through the first hydraulic telescopic rod 3, the slide plate 2 can be driven to slide on the upper end of the box body 1, thereby changing the position of the slide plate 2. When the slide plate 2 moves at the upper end of the box body 1, the two second hydraulic telescopic rods 7 at the lower end of the slide plate 2 will move synchronously with the slide plate 2, and the placement box will also move synchronously with the slide plate 2, and the position of the placement box can be controlled by controlling the extension and retraction of the output ends of the two second hydraulic telescopic rods 7. When it is necessary to place a polyurethane elastomer on the placement box, the placement box can be moved to a higher position by controlling the output ends of the two second hydraulic telescopic rods 7 to retract. Subsequently, the polyurethane elastomer can be placed on each blocking net 4 on the placement box through the operating window on one side of the upper part of the box body 1, and the deformation resistance of the blocking net 4 can be increased through the ring plate 5.

[0023] After the polyurethane elastomer is placed on the fence 4, the output ends of the two second hydraulic telescopic rods 7 are controlled to extend, driving the placement box and the polyurethane elastomer on the placement box to enter the inner bottom of the box body 1. The inner bottom of the box body 1 stores a surface treatment agent, and the polyurethane elastomer placed on the placement box needs to be completely immersed in the surface treatment agent. After the dipping is completed, the output ends of the two second hydraulic telescopic rods 7 are controlled to retract, driving the placement box and the polyurethane elastomer on the placement box to move upward. When the placement box rises to a predetermined height, the second hydraulic telescopic rod 7 stops moving, and then The first hydraulic telescopic rod 3 drives the slide plate 2 to move, and drives the placement box to move through the two second electric telescopic rods. When the placement box moves toward the inner side of the box body 1, the guide plate 8 can enter between two adjacent block nets 4. At this time, the surface treatment agent dripping on the polyurethane elastomer on the block net 4 will fall onto the guide plate 8 instead of dripping onto the polyurethane elastomer below. When the surface treatment agent on the polyurethane elastomer stops dripping, the placement box is pushed to move away from the guide plate 8 by the first electric telescopic rod, and the polyurethane elastomer on the placement box can be removed through the operation window.

[0024] Furthermore, the guide plate 8 is inclined, and the lower end of the guide plate 8 is inclined toward the inner bottom of the box body 1. The surface treatment agent dripping on the polyurethane elastomer drips onto the guide plate 8. The inclined guide plate 8 is convenient to accelerate the speed of the surface treatment agent flowing back to the inner bottom of the box body 1, and prevent the surface treatment agent from accumulating on the guide plate 8, which affects the recycling and reuse of the surface treatment agent.

[0025] The two ends of the spring 11 are respectively fixedly connected to the mounting groove 9 and the scraper 10 to prevent the scraper 10 from detaching from the mounting groove 9. When the lower end of the scraper 10 extends downward to the maximum distance, the lower end of the scraper 10 is located above the guide groove 12 to ensure that the scraper 10 can pass through the guide groove 12 and enter the upper part of the guide plate 8.

[0026] Furthermore, the height of the middle part of the material guide trough 12 is higher than the height to the two ends of the material guide trough 12. The surface treatment agent located in the material guide trough 12 can move faster to the two sides of the material guide trough 12 and flow back to the bottom of the box through the two sides of the material guide trough 12, thereby preventing the scraper 10 from pushing the surface treatment agent on the material guide plate 8 back onto the polyurethane elastomer on the blocking net 4 when the box is placed away from the material guide plate 8.

[0027] Furthermore, a storage box 13 is provided on one side of the box body 1, and a liquid pump 14 is provided inside the storage box 13. Unused surface treatment agent is stored in the storage box 13. When the amount of surface treatment agent at the bottom of the box body 1 is small, the surface treatment agent in the storage box 13 is quickly replenished into the box body 1 through the liquid pump 14, thereby not affecting the treatment of the polyurethane elastomer in the box body 1.

[0028] The device can, through the provided material guide plate 8, make the surface treatment agent dripping from the surface of the polyurethane elastomer on the blocking nets 4 at different heights drip onto the material guide plate 8 below each blocking net 4 and closest to it, that is, the surface treatment agent on the polyurethane elastomer will not drip onto the polyurethane elastomer located on the blocking net 4 below, and the dripping rate of the surface treatment agent on the polyurethane elastomer on the blocking net 4 at each height is roughly the same, thereby shortening the time for the surface treatment agent to flow back into the box 1 and ensuring appropriate treatment efficiency and good use effect. At the same time, the provided scraper 10 and material guide trough 12 can improve the efficiency of the treatment agent on the upper surface of the material guide plate flowing back into the box 1.
