Description

Technical Field

[0001] This utility model relates to the field of materials processing technology, specifically to a uniform coating device for adhesives. Background Technology

[0002] In modern industrial production, adhesives are increasingly widely used. From packaging to electronics manufacturing, from automobile assembly to construction, adhesives play a vital role in connection and fixation across various fields. However, to achieve high-quality adhesive bonding, uniform application of the adhesive is crucial.

[0003] As adhesive accumulates on the extrusion rollers, it alters the shape and roughness of the roller surface, making it difficult to apply the adhesive evenly to the substrate during subsequent coating processes. This can result in areas that are too thick or too thin, affecting the uniformity of the coating. Products that should have a uniform coating thickness may exhibit significant thickness differences in certain areas due to adhesive buildup on the extrusion rollers, thus reducing product quality. Utility Model Content

[0004] The purpose of this invention is to provide a uniform adhesive coating device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a uniform coating device for adhesives, including a machine tool and a uniform roller. A servo motor is installed on the outer wall of the machine tool, and a reducer is provided at the drive end of the servo motor. The drive end of the servo motor is connected to a drive gear, which meshes with a driven gear. The driven gear is rotatably connected to the inner wall of the machine tool. A reciprocating screw is provided on one side of the driven gear. An electric telescopic rod is fixedly installed at the end of the reciprocating screw near the driven gear. A cross block is connected to the telescopic end of the electric telescopic rod. A groove adapted to the cross block is opened on the driven gear. A slider is threadedly connected to the outer wall of the reciprocating screw. A cleaning ring is fixedly installed at the bottom of the slider and is sleeved on the outer circumference of the uniform roller.

[0006] Furthermore, an mounting plate is fixedly installed on the inner wall of the machine tool, a fixing block is fixedly installed on the bottom of the mounting plate, and the reciprocating lead screw is installed between the fixing block and the inner wall of the machine tool.

[0007] Furthermore, a transmission device is provided at the inner bottom of the machine tool, the drive end of the servo motor is fixedly connected to the main conveying roller on the transmission device, and the drive gear is fixedly installed on the outer wall of the main conveying roller.

[0008] Furthermore, one end of the uniform roller is rotatably connected to the inner wall of the machine tool, and the other end of the uniform roller is rotatably connected to the fixed block.

[0009] Furthermore, a spraying device is installed above the machine tool, and a limit rod is fixedly installed between the machine tool and the fixed block, with the slider sliding to connect to the outer wall of the limit rod.

[0010] Furthermore, the cross block is composed of a main component and a sub-component, with the sub-component slidably connected to the main component. A guide telescopic rod and a return spring are fixedly installed between the main component and the sub-component, with the return spring sleeved on the outer wall of the guide telescopic rod.

[0011] Furthermore, the guide telescopic rod and the return spring are arranged in an equidistant array.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the servo motor drive end drives the reducer to transport the material after the adhesive is sprayed to the direction of the uniform roller. The uniform roller can make the adhesive on the surface of the material uniform, but it is necessary to clean the surface in time, otherwise the accumulation of adhesive will affect the uniformity of subsequent coating. At this time, the servo motor drive end drives the driven gear to rotate through the active transmission roller. The reducer is started to slow down the speed of the active gear and the driven gear. The telescopic end of the electric telescopic rod moves forward. The cross block sub-component abuts against the driven gear. The guide telescopic rod and the return spring retract. When the driven gear slot and the cross block are at the appropriate angle, the return spring pushes the sub-component into the slot. Then, the electric telescopic rod is controlled to move forward to push the cross block into the slot. The driven gear drives the reciprocating screw to rotate through the cross block and the electric telescopic rod, so that the slider drives the cleaning ring to clean the outer wall of the uniform roller and prevent the adhesive from solidifying and affecting the uniformity of coating.

[0014] 2. In this invention, the guide telescopic rod provides stable guidance for the sliding of the sub-component. This ensures that the sub-component maintains linear motion during sliding, avoiding deviation or wobbling, thereby guaranteeing the stability and reliability of the cross block under different conditions.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figures 1-6 This utility model provides a technical solution:

[0024] See Figures 1-6 As shown, a uniform coating device for adhesives includes a machine tool 1 and a uniform roller 12. A servo motor 3 is mounted on the outer wall of the machine tool 1. A reducer 4 is provided at the drive end of the servo motor 3. A drive gear 5 is connected to the drive end of the servo motor 3. A driven gear 6 is meshed with the drive gear 5. The driven gear 6 is rotatably connected to the inner wall of the machine tool 1. A reciprocating screw 9 is provided on one side of the driven gear 6. An electric telescopic rod 7 is fixedly installed at one end of the reciprocating screw 9 near the driven gear 6. A cross block 8 is connected to the telescopic end of the electric telescopic rod 7. A slot 18 adapted to the cross block 8 is opened on the driven gear 6. A slider 10 is threadedly connected to the outer wall of the reciprocating screw 9. A cleaning ring 11 is fixedly installed at the bottom of the slider 10. The cleaning ring 11 is sleeved on the outer circumference of the uniform roller 12.

[0025] It should be noted that the servo motor 3, the reducer 4, and the microcontroller are all powered by external power sources.

[0026] The drive end of the servo motor 3 drives the reducer 4 to convey the material from the spraying device 2 to the uniform roller 12 after the adhesive has been sprayed. The uniform roller 12 can evenly apply the adhesive to the surface of the material. Afterwards, the surface of the uniform roller 12 should be cleaned in time. Otherwise, the accumulation of adhesive on the extrusion roller will change the shape and roughness of the roller surface, making it impossible to evenly apply the adhesive to the substrate in the subsequent coating process.

[0027] The servo motor 3 drives the driven gear 6 to rotate via the active transmission roller. Simultaneously, the reducer 4 is activated, slowing down the rotation speed of the active gear 5 and the driven gear 6. At this time, the telescopic end of the electric telescopic rod 7 moves forward, causing the sub-component of the cross block 8 to abut against the driven gear 6. The guide telescopic rod 14 and the return spring 15 retract. When the slot 18 on the driven gear 6 rotates to an angle suitable for the cross block 8, the return spring 15 pushes the sub-component of the cross block 8 into the slot 18. Then, the electric telescopic rod 7 is controlled to move forward, extending the entire cross block... Block 8 is pushed into slot 18. Driven gear 6 drives reciprocating screw 9 to rotate through cross block 8 and electric telescopic rod 7, causing slider 10 to reciprocate laterally on the outer wall of reciprocating screw 9. Slider 10 drives cleaning ring 11 to clean the outer wall of uniform roller 12. The adhesive on uniform roller 12 falls onto the collection box below, preventing the adhesive on uniform roller 12 from solidifying due to failure to clean it in time. This would prevent the adhesive from being applied evenly to the substrate in the subsequent coating process, which may result in local over-thickness or under-thickness, affecting the uniformity of coating.

[0028] See Figure 1-3 A mounting plate 13 is fixedly installed on the inner wall of the machine tool 1, and a fixing block 17 is fixedly installed on the bottom of the mounting plate 13. The reciprocating screw 9 is installed between the fixing block 17 and the inner wall of the machine tool 1.

[0029] The mounting plate 13 is fixedly mounted on the inner wall of the machine tool 1, providing a stable mounting base for the entire device. The inner wall of the machine tool 1 typically has high strength and rigidity, which can effectively support the mounting plate 13 and the components on it, reducing shaking and vibration during operation.

[0030] The fixing block 17 at the bottom of the mounting plate 13 further enhances the fixing effect on the reciprocating lead screw 9. The fixing block 17 and the inner wall of the machine tool 1 together clamp the reciprocating lead screw 9, making it more stable during operation and reducing the problem of uneven coating caused by lead screw wobbling.

[0031] See Figure 1-2 The machine tool 1 has a transmission device 16 at its inner bottom. The drive end of the servo motor 3 is fixedly connected to the main conveying roller on the transmission device 16, and the drive gear 5 is fixedly installed on the outer wall of the main conveying roller.

[0032] A conveyor device 16 is installed at the bottom of the machine tool 1, which provides a stable conveying platform for the material to be coated. The conveyor device 16 can continuously transport the material to the coating area, improving production efficiency.

[0033] The drive end of the servo motor 3 is fixedly connected to the main conveyor roller on the transmission device 16, enabling precise control of the conveying speed and position. The servo motor features fast response and high precision, allowing for real-time adjustment of the material conveying speed according to the coating process requirements, ensuring uniform coating.

[0034] See Figure 1-3 One end of the uniform roller 12 is rotatably connected to the inner wall of the machine tool 1, and the other end of the uniform roller 12 is rotatably connected to the fixed block 17.

[0035] When the uniform roller 12 presses onto the material, it applies a certain pressure to the adhesive. This pressure causes the adhesive to flow on the material surface, filling the fine unevenness of the material surface, thereby reducing uneven coating caused by surface roughness. On some slightly textured material surfaces, the pressure of the uniform roller 12 can push the adhesive into the texture, making the adhesive distribution more uniform across the entire surface.

[0036] The pressure of the uniform roller 12 helps control the coating thickness of the adhesive. By adjusting the pressure of the uniform roller 12 on the material, the thickness of the adhesive on the material surface can be changed. If the pressure is appropriate, the uniform roller 12 can squeeze out excess adhesive, making the coating thickness more uniform. At the same time, for adhesives of different viscosities, appropriate pressure can ensure that a uniform thickness layer is formed on the material surface.

[0037] See Figure 1-3 A spraying device 2 is installed above the machine tool 1. A limit rod is fixedly installed between the machine tool 1 and the fixed block 17. The slider 10 slides to connect to the outer wall of the limit rod.

[0038] A spraying device 2 is installed above the machine tool 1, which can achieve precise spraying of materials. The spraying device usually has adjustable spraying parameters, such as spraying pressure, flow rate and angle, which can be precisely adjusted according to different adhesives and material requirements to ensure that the adhesive is evenly sprayed on the material surface.

[0039] A limiting rod is fixedly installed between the machine tool 1 and the fixed block 17, and the slider 10 is slidably connected to the outer wall of the limiting rod. This design restricts the movement direction of the slider 10, allowing it to move only in a straight line along the limiting rod. During the coating process, the slider 10 may be connected to the coating component or other moving mechanisms. The constraint of the limiting rod ensures that the movement trajectory of the coating component is accurate, thereby improving the coating precision.

[0040] See Figure 5 The cross block 8 is composed of a main component and a sub-component. The sub-component is slidably connected to the main component. A guide telescopic rod 14 and a return spring 15 are fixedly installed between the main component and the sub-component. The return spring 15 is sleeved on the outer wall of the guide telescopic rod 14.

[0041] The guide telescopic rod 14 provides stable guidance for the sliding of the sub-component. This ensures that the sub-component maintains linear motion during sliding, avoiding deviation or wobbling, thereby guaranteeing the stability and reliability of the cross block 8 under different conditions.

[0042] See Figure 5 The guide telescopic rod 14 and the return spring 15 are arranged in an equidistant array.

[0043] The guide telescopic rods 14 and the return springs 15 are arranged in an equidistant array, which makes the force on the main component and the sub-component of the cross block 8 more uniform in all directions. When the cross block 8 is subjected to external force, each guide telescopic rod 14 and return spring 15 can share the force simultaneously, avoiding excessive local force that could lead to structural damage or deformation.

[0044] Working principle: The drive end of the servo motor 3 drives the reducer 4 to convey the material after the adhesive has been sprayed from the spraying device 2 to the uniform roller 12. The uniform roller 12 can evenly apply the adhesive to the surface of the material. Afterwards, the surface of the uniform roller 12 should be cleaned in time. Otherwise, the accumulation of adhesive on the extrusion roller will change the shape and roughness of the roller surface, making it impossible to evenly apply the adhesive to the substrate in the subsequent coating process.

[0045] The servo motor 3 drives the driven gear 6 to rotate via the active transmission roller. Simultaneously, the reducer 4 is activated, slowing down the rotation speed of the active gear 5 and the driven gear 6. At this time, the telescopic end of the electric telescopic rod 7 moves forward, causing the sub-component of the cross block 8 to abut against the driven gear 6. The guide telescopic rod 14 and the return spring 15 retract. When the slot 18 on the driven gear 6 rotates to an angle suitable for the cross block 8, the return spring 15 pushes the sub-component of the cross block 8 into the slot 18. Then, the electric telescopic rod 7 is controlled to move forward, extending the entire cross block... Block 8 is pushed into slot 18. Driven gear 6 drives reciprocating screw 9 to rotate through cross block 8 and electric telescopic rod 7, causing slider 10 to reciprocate laterally on the outer wall of reciprocating screw 9. Slider 10 drives cleaning ring 11 to clean the outer wall of uniform roller 12. The adhesive on uniform roller 12 falls onto the collection box below, preventing the adhesive on uniform roller 12 from solidifying due to failure to clean it in time. This would prevent the adhesive from being applied evenly to the substrate in the subsequent coating process, which may result in local over-thickness or under-thickness, affecting the uniformity of coating.
