Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and in particular to a compatibilizer surface modification coating equipment. Background Technology

[0002] Compatibilizers, also known as compatibilizers, are additives that promote the bonding of two or more incompatible polymers through intermolecular bonding forces. In polymer alloy systems, compatibilizers can reduce interfacial tension, increase interfacial layer thickness, and reduce dispersed particle size, enabling the system to ultimately form a thermodynamically stable phase structure with macroscopic uniformity and microscopic phase separation characteristics. Surface modification coating technology refers to forming a coating with specific properties on the surface of a material through physical or chemical methods to improve the surface properties of the material or endow it with new functions. For compatibilizers, surface modification coating technology can ensure that the compatibilizer is uniformly and firmly attached to the surface of the plate, improving its compatibility and bonding force with the base material.

[0003] Currently, various coating equipment exists on the market, but dedicated equipment for compatibilizer surface modification coating is relatively rare. Existing equipment often suffers from the following problems during the coating process: the tanks used to store the compatibilizer solution are not equipped with an effective stirring structure. This design oversight causes the compatibilizer solution to solidify after prolonged coating operations. Solidification not only alters the original fluidity of the compatibilizer solution but also creates severe discharge difficulties during subsequent use. Because the solidified compatibilizer solution cannot flow smoothly, the coating equipment cannot obtain a stable and uniform liquid supply during operation, directly leading to uneven coating results.

[0004] Furthermore, we disclose a compatibilizer surface modification coating device to meet the practical needs of compatibilizer liquids in the prior art, which are prone to solidification during operation, resulting in difficult discharge. Utility Model Content

[0005] The purpose of this invention is to provide a compatibilizer surface modification coating device to solve the problem of easy solidification of compatibilizer liquid during operation, which leads to difficulty in material discharge in the prior art.

[0006] To achieve the above objectives, this utility model provides a compatibilizer surface modification coating device, comprising a base, two support rods fixedly connected to both sides of the upper end of the base, and transmission groove blocks fixedly connected to the upper ends of the two support rods on both sides. Transmission components are provided on the two transmission groove blocks. A liquid storage tank is provided at the upper middle part of the base. The transmission components are used to drive the liquid storage tank to reciprocate at the upper end of the base to complete the coating work on the substrate. Slider blocks are fixedly connected to both end faces of the liquid storage tank. One end of each slider is slidably connected to the two transmission groove blocks. A stirring component is provided in the middle of the liquid storage tank. When the liquid storage tank moves, the stirring component is used to stir the compatibilizer liquid inside the liquid storage tank. A roller that contacts the substrate surface for coating is provided at the lower end of the liquid storage tank. A control component is provided at the lower end of the liquid storage tank. The control component is used to adjust the distance between the roller and the liquid storage tank.

[0007] Preferably, the transmission assembly includes a lead screw and a guide rod. The lead screw and the guide rod are respectively connected to sliders at both ends of the liquid storage tank. The lead screw is driven by the sliders, and the guide rod is slidably connected to the sliders. The lead screw is rotatably engaged inside the transmission groove block, and the guide rod is fixedly connected inside the transmission groove block. A servo motor is installed at one end of the transmission groove block located on one side of the lead screw, and the output end of the servo motor is fixedly connected to the lead screw.

[0008] Preferably, the stirring assembly includes a stirring rod that is rotatably connected to the lower part of the middle of the liquid storage tank. Both ends of the stirring rod pass through the liquid storage tank and are fixedly connected to gears. One side of the lower end face of each of the two gears is fixedly connected to a toothed plate, and each of the two gears is respectively meshed with the two toothed plates.

[0009] Preferably, sealing sleeves are fixedly connected to the lower middle part of both end faces of the liquid storage tank, the stirring rod passes through the sealing sleeves, and a sealing structure is provided at the connection between the stirring rod and the sealing sleeves.

[0010] Preferably, the control component includes two brackets that are respectively engaged and rotatably connected to both ends of the roller. A rotating seat is fixedly connected to one side of the upper end of each of the two brackets, and a roller is rotatably connected to the upper end of each of the two rotating seats. A sliding groove is provided at the lower middle of the middle of both end faces of the liquid storage tank. One side of the upper end of the bracket is slidably connected to the inside of the sliding groove. A tension spring is fixedly connected to the middle of the upper end face of the bracket. A fixing plate is fixedly connected to the upper end of the tension spring, and one end of the fixing plate is fixedly connected to the liquid storage tank.

[0011] Preferably, the control component further includes two abutments fixedly connected to the lower ends of the two transmission slot blocks, both ends of the abutments being inclined toward one side of the transmission slot blocks, and the outer wall of the roller contacting the lower end surface of the abutment.

[0012] Preferably, suction cups are provided at the four corners of the upper surface of the base, and multiple abutment springs are fixedly connected to both sides of the middle part of the upper surface of the base, with a cone fixedly connected to the upper end of each of the multiple abutment springs.

[0013] The beneficial effects of this utility model are:

[0014] This compatibilizer surface modification coating equipment is equipped with a stirring component. During the coating operation, as the liquid storage tank moves, the stirring rod in the stirring component rotates continuously under the meshing action of the toothed plate and gears, fully stirring the compatibilizer liquid to maintain its good fluidity and prevent the compatibilizer liquid from solidifying. This not only ensures that the compatibilizer liquid can flow smoothly during subsequent use, providing a stable and uniform liquid supply for the coating equipment, but also makes the coating effect more uniform, improves the overall quality of the product, and effectively overcomes the technical problems of difficult discharge and uneven coating caused by the solidification of the compatibilizer liquid in the prior art.

[0015] This compatibilizer surface modification coating equipment is equipped with a control component. A tension spring within the control component ensures the rollers remain in close contact with the backing plate. As the storage tank moves, the rollers roll on the backing plate. When they reach the inclined ends of the backing plate, they cause the rollers to fit tightly against the lower end of the storage tank. This design allows for precise control of the distance between the rollers and the storage tank. When coating is not required, the storage tank is typically located at both ends of the transmission trough, ensuring a tight fit and effectively preventing adhesive leakage from the lower end of the storage tank. This avoids adhesive waste and unnecessary contamination of the substrate, solving the problem of adhesive leakage during non-coating periods due to the difficulty in accurately controlling the drain outlet. Furthermore, this control component eliminates the need for an electrically controlled valve, avoiding increased costs and complex maintenance associated with such valves. This reduces the overall manufacturing cost and maintenance difficulty of the equipment, improving its economy and practicality, making this compatibilizer surface modification coating equipment more advantageous in practical applications.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0023] like Figures 1 to 4 As shown, a compatibilizer surface modification coating device includes a base 1. Two support rods 2 are fixedly connected to both sides of the upper end of the base 1. Transmission groove blocks 3 are fixedly connected to the upper ends of the two support rods 2. Transmission components are provided on the two transmission groove blocks 3. A liquid storage tank 4 is provided at the upper middle part of the base 1. The transmission components are used to drive the liquid storage tank 4 to reciprocate at the upper end of the base 1 to complete the coating work on the board. Slider blocks 12 are fixedly connected to both end faces of the liquid storage tank 4. One end of each slider 12 is slidably connected to the two transmission groove blocks 3. A stirring component is provided in the middle of the liquid storage tank 4. When the liquid storage tank 4 moves, the stirring component is used to stir the compatibilizer liquid inside the liquid storage tank 4. A roller 6 is provided at the lower end of the liquid storage tank 4 to contact the surface of the board for coating. A control component is provided at the lower end of the liquid storage tank 4. The control component is used to adjust the distance between the roller 6 and the liquid storage tank 4.

[0024] The compatibilizer surface modification coating device is equipped with a transmission component. The servo motor 5 drives the lead screw 13 to rotate, which, together with the guide rod 10, causes the liquid storage tank 4 to reciprocate on the upper end of the base 1, realizing the coating operation on the board. The liquid storage tank 4 is equipped with a stirring component. When the liquid storage tank 4 moves, the stirring rod 11 rotates under the meshing action of a rack and pinion 21, which fully stirs the compatibilizer liquid, avoids it from standing and solidifying for a long time, and ensures that the compatibilizer liquid is discharged smoothly and coated evenly. At the same time, the control component uses the tension spring 15 to keep the roller 22 and the backing plate 2 With close contact, the rollers 22 roll on the back plate 20 as the liquid storage tank 4 moves. When they reach the inclined ends of the back plate 20, they drive the rollers 6 to fit tightly against the lower end of the liquid storage tank 4, precisely controlling the distance between them to prevent the adhesive from seeping out during non-coating periods. Moreover, there is no need for an electrically controlled valve body, which reduces costs and maintenance difficulty. Through the coordinated work of various components, this device achieves effective stirring, precise coating, and reliable control of the drain outlet for the compatibilizer liquid, improving coating quality and efficiency, reducing production costs, and providing a reliable guarantee for compatibilizer surface modification coating operations.

[0025] Furthermore, such as Figures 1 to 2As shown, the transmission assembly includes a lead screw 13 and a guide rod 10. The lead screw 13 and the guide rod 10 are respectively connected to the sliders 12 at both ends of the liquid storage tank 4. The lead screw 13 is connected to the sliders 12 in a transmission connection, and the guide rod 10 is connected to the sliders 12 in a sliding connection. The lead screw 13 is engaged and rotatably connected inside the transmission groove block 3, and the guide rod 10 is fixedly connected inside the transmission groove block 3. A servo motor 5 is installed at one end of the transmission groove block 3 on one side of the lead screw 13, and the output end of the servo motor 5 is fixedly connected to the lead screw 13.

[0026] The servo motor 5 is installed on one end face of the transmission slot block 3 located on one side of the lead screw 13. Its output end is fixedly connected to the lead screw 13. When the servo motor 5 is started, it will drive the lead screw 13 to engage and rotate inside the transmission slot block 3. At the same time, the slider 12 on one side, which is connected to the lead screw 13, will move linearly along the transmission slot block 3 under the rotation of the lead screw 13. The slider 12 on the other side is slidably connected to the guide rod 10 fixedly connected inside the transmission slot block 3 on the other side. The guide rod 10 plays a guiding and supporting role, ensuring that the slider 12 on this side can move linearly along the transmission slot block 3 stably. Since the two end faces of the liquid storage tank 4 are fixedly connected to the two sliders 12 respectively, the liquid storage tank 4 can reciprocate at the upper end of the base 1 under the synchronous linear movement of the two sliders 12, thereby completing the coating work of the plate.

[0027] Furthermore, such as Figures 1 to 3 As shown, the stirring assembly includes a stirring rod 11 that is rotatably connected to the lower part of the middle of the liquid storage tank 4. Both ends of the stirring rod 11 pass through the liquid storage tank 4 and are fixedly connected to gears 21. One side of the lower end face of each of the two gears 21 is fixedly connected to a toothed plate 19. Each of the two gears 21 meshes with the two toothed plates 19 respectively. Both sides of the liquid storage tank 4 are fixedly connected to the lower part of the middle of the two end faces. The stirring rod 11 passes through the sealing sleeve 18, and a sealing structure is provided at the connection between the stirring rod 11 and the sealing sleeve 18.

[0028] When the storage tank 4 moves under the drive of the transmission assembly, the stirring rod 11, which is rotatably connected to the lower middle part of the storage tank 4, moves along with the storage tank 4. Both ends of the stirring rod 11 pass through the storage tank 4 and are fixedly connected to gears 21, while the gear plate 19 is fixedly connected to the transmission groove block 3. When the storage tank 4 moves, the gears 21 mesh with the gear plate 19, causing the gears 21 to rotate, which in turn drives the stirring rod 11 to rotate. Thus, during the movement of the storage tank 4, the stirring rod 11 continuously rotates, stirring the compatibilizer liquid inside the storage tank 4. Simultaneously, the stirring rod 11 passes through the sealing sleeve 18, and a sealing structure is provided at the connection point, ensuring the airtightness of the storage tank 4 and preventing leakage of the compatibilizer liquid.

[0029] Furthermore, such as Figures 1 to 4As shown, the control component includes two brackets 14 that are respectively engaged and rotatably connected to both ends of the roller 6. A rotating seat 23 is fixedly connected to one side of the upper end of each of the two brackets 14. A roller 22 is rotatably connected to the upper end of each of the two rotating seats 23. A sliding groove 16 is opened at the lower end of the middle of the two end faces of the liquid storage tank 4. One side of the upper end of the bracket 14 is slidably connected to the inside of the sliding groove 16. A tension spring 15 is fixedly connected to the middle of the upper end face of the bracket 14. A fixing plate 17 is fixedly connected to the upper end of the tension spring 15. One end of the fixing plate 17 is fixedly connected to the liquid storage tank 4. The control component also includes two abutments 20 that are respectively fixedly connected to the lower ends of the two transmission slot blocks 3. Both ends of the abutments 20 are inclined and tilted towards one side of the transmission slot block 3. The outer wall of the roller 22 is in contact with the lower end face of the abutment 20.

[0030] Two brackets 14 are respectively engaged and rotatably connected to both ends of the roller 6. A roller 22 is rotatably connected to a rotating seat 23 fixedly connected to one side of the upper end of the bracket 14. The upper side of the bracket 14 is slidably connected to a groove 16 opened at the lower end of the middle of the two end faces of the liquid storage tank 4. The middle of the upper end face of the bracket 14 is connected to a fixed plate 17 through a tension spring 15. One end of the fixed plate 17 is fixedly connected to the liquid storage tank 4, so that the roller 22 is always in close contact with the lower end face of the abutment plate 20 fixedly connected to the lower end of the two transmission groove blocks 3 under the action of the tension spring 15. When the liquid storage tank 4 moves under the drive of the transmission assembly, it will drive the roller 22 to abut the abutment plate 20. Rolling on plate 20, since both ends of plate 20 are inclined and tilted towards the transmission groove block 3, when roller 22 rolls to both ends of plate 20, under the action of the inclined surface of plate 20, bracket 14 will drive roller 6 to move upward, so that the entire roller 6 is tightly fitted with the lower end of liquid storage tank 4. Since the lower end of liquid storage tank 4 is a circular groove with the same diameter as roller 6, when the two are tightly fitted, it can effectively prevent glue leakage. When liquid storage tank 4 moves, a distance will be maintained between roller 6 and liquid storage tank 4, thereby realizing the control of the distance between roller 6 and liquid storage tank 4, ensuring the normal progress of coating work.

[0031] Furthermore, such as Figure 1 As shown, suction cups 9 are provided at the four corners of the upper surface of the base 1, and multiple abutment springs 7 are fixedly connected to both sides of the middle part of the upper surface of the base 1. Conical cylinders 8 are fixedly connected to the upper ends of the multiple abutment springs 7.

[0032] When using this coating equipment, the board to be coated is placed on four suction cups 9. Due to the weight of the board, the four suction cups 9 will firmly hold the board. When the board is too heavy and falls a certain distance, it will contact the cone 8 and cause the anti-spring 7 to be compressed. The anti-spring 7 completes the load-bearing work and avoids the suction cups 9 from deforming too much and failing to limit the board. In addition, since the board to be coated needs to be flat, the suction cups 9 can hold the board.
