Description

Technical Field

[0001] This utility model relates to the technical field of adhesive coating devices, and in particular to an adhesive coating device for rubber products. Background Technology

[0002] In the rubber products industry, it is often necessary to apply adhesive to various rubber products to facilitate subsequent attachment processes. Existing technologies disclose various devices for applying adhesive to rubber products. For example, Chinese utility model patent CN222829972U discloses an automatic rubber product adhesive application device. This device includes an operating table with a storage rack and a support frame. A support plate is located on one side of the top of the support frame, and an electric telescopic rod is located at the bottom of the support plate. A drive motor is located at the output end of the electric telescopic rod, and an adjusting disc is located at the output end of the drive motor. An adjusting groove is formed on the adjusting disc, and an adjusting motor is located at one end of the adjusting groove. A lead screw is located at the output end of the adjusting motor and the other end of the adjusting groove. A sliding block is located on the lead screw, and the sliding block is slidably connected to the adjusting groove. This device can automatically apply adhesive to rubber products. Furthermore, by controlling the adjusting motor, the position of the injection tube can be adjusted according to the diameter of different shaped rubber products, thus facilitating adhesive application to ring-shaped rubber products of different sizes.

[0003] However, the above-mentioned existing glue-applying devices and most of them have glue nozzles arranged downwards and apply glue to the upper surface of the rubber products. After the glue is applied, the glue remaining in the glue nozzle is easy to drip onto the worktable under the action of gravity, causing the worktable to be contaminated. Moreover, after the glue is applied, the rubber products are inconvenient to unload due to the obstruction of the glue nozzle mechanism above them. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a rubber product coating device that applies adhesive from bottom to top, can receive and collect residual adhesive, avoids adhesive dripping and contaminating the platform, and makes material unloading more convenient.

[0005] This utility model discloses a rubber product coating device, comprising a base plate and a material rack. The material rack is located above the base plate and clamps the rubber product on its lower surface. It also includes a glue pump, a glue delivery pipe, a glue nozzle, a glue receiving hopper, and a drive mechanism. The glue pump and drive mechanism are mounted on the base plate, and the glue delivery pipe is mounted on the drive mechanism. The output end of the glue pump is connected to the lower end of the glue delivery pipe via the glue delivery pipe. The drive mechanism moves the glue delivery pipe below the material rack. The glue nozzle is mounted on the upper end of the glue delivery pipe, and the glue receiving hopper is mounted on the middle of the outer wall of the glue nozzle, used to collect glue dripping from the upper end of the glue nozzle. During operation, a suitable material rack is selected according to the style of the rubber product, and the rubber product is clamped onto the material rack. On the lower surface of the rack, the glue pump operates to deliver glue through the glue delivery pipe. After entering the glue delivery pipe, the glue is output through the upper port of the nozzle. At the same time, the drive mechanism moves the glue delivery pipe along the glue application path matched to the rubber product, so that the nozzle applies glue to the surface of the rubber product. When excess glue drips from the surface of the rubber product, it is caught and collected by the glue receiving hopper. After the glue application is completed, the rubber product on the lower surface of the material rack is removed, and the remaining glue dripping from the upper port of the nozzle falls into the glue receiving hopper for collection. Compared with the existing technology, the glue application is done from bottom to top, and the glue receiving hopper receives and collects the residual glue, avoiding glue dripping and contaminating the platform. Without the obstruction of the nozzle, the rubber product is easier to remove and the unloading is more convenient.

[0006] Preferably, it also includes a hinge seat, a cover plate, and a hinge shaft. The hinge seat is installed in the glue receiving hopper. The lower end of the cover plate is rotatably connected to the hinge seat through the hinge shaft. An elastic component is provided between the cover plate and the hinge seat. The elastic force of the elastic component causes the upper end of the cover plate to press against the upper port of the glue nozzle. When no glue is applied, the elastic force of the elastic component causes the upper end of the cover plate to close the upper port of the glue nozzle, further preventing residual glue from overflowing. When applying glue, the upper end of the cover plate is blocked by the rubber product, thereby opening the upper port of the glue nozzle without affecting the glue application work.

[0007] Preferably, it also includes a gear, a baffle, and a toothed groove. A recovery hole is provided at the bottom of the side wall of the nozzle, communicating with the internal channel of the nozzle. The gear is concentrically mounted on a hinge shaft. The baffle is slidably mounted on the outer wall of the nozzle, and has a glue inlet hole matching the recovery hole. A toothed groove is installed on the baffle, meshing with the gear. The glue pump has a back-pull function, capable of drawing residual glue from the glue delivery tube and nozzle back into the glue tank. When not applying glue, the upper end of the cover plate closes the upper port of the nozzle. At this time, the glue inlet hole of the baffle aligns with the recovery hole of the nozzle. At this point, the glue pump's backflow function is activated, drawing the residual glue collected in the glue receiving hopper back into the nozzle's channel through the recycling hole and glue inlet hole for reuse. During glue application, the cover plate is blocked by the rubber product and flips over, causing the lower end of the cover plate to drive the hinge shaft to rotate. The hinge shaft drives the gear to rotate, and the gear meshing groove drives the baffle to rise along the outer wall of the nozzle, causing the glue inlet hole and recycling hole to be misaligned. This allows the baffle to close the recycling hole of the nozzle. At this time, when the glue pump is running and delivering glue, the glue will not overflow through the recycling hole of the nozzle and the glue inlet hole of the baffle.

[0008] Preferably, the drive mechanism includes a motor, a mounting platform, a slide rail, a slide table, a lead screw, a top plate, and a stepper motor. The motor is mounted on the base plate, the mounting platform is mounted on the output shaft of the motor, the inner end of the slide rail is horizontally mounted on the mounting platform, the slide table is slidably mounted on the slide rail, the inner end of the lead screw is rotatably connected to the mounting platform, and the lead screw and the slide table are connected via a lead screw nut. The slide rail is parallel to the lead screw, and the outer ends of the slide rail and the lead screw are connected to the top plate. The stepper motor is mounted on the top plate, and the output shaft of the stepper motor is connected via a lead screw. The glue delivery tube is mounted on the slide table. The output shaft of the motor drives the mounting platform to rotate, thereby driving the glue delivery tube and the nozzle to move circumferentially through the slide rail and the lead screw. The stepper motor drives the lead screw to rotate, and the lead screw drives the slide table to move along the slide rail through the lead screw nut, thereby driving the glue delivery tube and the nozzle to move linearly and adjusting the distance between the nozzle and the mounting platform, thus realizing automatic glue application for square and round rubber products.

[0009] Preferably, it also includes a second motor, a bevel gear, and a bevel gear ring. The second motor is mounted on the slide table, the bevel gear is concentrically mounted on the output shaft of the second motor, and the bevel gear ring is concentrically mounted on the glue delivery pipe. The bevel gear meshes with the bevel gear ring. The second motor drives the bevel gear to rotate, and the bevel gear meshing with the bevel gear ring drives the glue delivery pipe, the glue nozzle, and the glue receiving hopper to rotate, thereby adjusting the upper end of the cover plate to face the same direction as the glue nozzle, so that the cover plate remains open during glue application.

[0010] Preferably, the assembly also includes a second slide, a lifting rod, a fixed base, a first turntable, a second turntable, and a connector. The second slide is movably mounted on the base plate. The fixed end of the lifting rod is mounted on the second slide. The fixed base is mounted on the top of the piston rod of the lifting rod. The first turntable is mounted on the fixed base. The second turntable is concentrically mounted on the end face of the first turntable. A locking component is provided between the second turntable and the first turntable. The connector is mounted on the second turntable and has a structure for quick assembly and disassembly with the material rack. The quick assembly and disassembly structure includes a dovetail groove and a dovetail locking block structure. The material rack is connected to the dovetail groove of the connector through the dovetail locking block. Rotating the material rack causes the second turntable to flip relative to the first turntable. At this time, the structure on the material rack that holds the rubber product faces the same direction, making it convenient to hold the rubber product on the material rack and to remove the rubber product after it has been coated with glue. When applying glue, the material rack is flipped so that the rubber product faces down. After the material rack is adjusted, the locking component locks the first turntable and the second turntable. The piston rod of the lifting rod extends and retracts, causing the rubber product to rise and fall, so that the nozzle and the rubber product are kept at a suitable distance.

[0011] Compared with the prior art, the advantages of this utility model are as follows: the glue is applied from bottom to top, and the residual glue is received and collected by the glue receiving hopper, which avoids glue dripping and contaminating the platform. Without the obstruction of the glue nozzle, rubber products are easier to remove and the unloading is more convenient. Attached Figure Description

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0020] Example 1

[0021] like Figures 1 to 5As shown, a rubber product coating device includes a base plate 1 and a material rack 2. The material rack 2 is located above the base plate 1 and clamps the rubber product on its lower surface. It also includes a glue pump 3, a glue delivery pipe 4, a glue nozzle 5, a glue receiving hopper 6, and a drive mechanism. The glue pump 3 is mounted on the base plate 1, the drive mechanism is mounted on the base plate 1, and the glue delivery pipe 4 is mounted on the drive mechanism. The output end of the glue pump 3 is connected to the lower end of the glue delivery pipe 4 via the glue delivery pipe. The drive mechanism drives the glue delivery pipe 4 to rotate on the material rack. The nozzle 5 is installed on the upper end of the glue delivery tube 4, and the glue receiving hopper 6 is installed in the middle of the outer wall of the nozzle 5. The glue receiving hopper 6 is used to collect the glue dripping from the upper end of the nozzle 5. The drive mechanism includes a motor 13, a mounting platform 14, a slide rail 15, a slide table 16, a lead screw 17, a top plate 18, and a stepper motor 19. The motor 13 is installed on the base plate 1, the mounting platform 14 is installed on the output shaft of the motor 13, the inner end of the slide rail 15 is horizontally installed on the mounting platform 14, and the slide table 16 is slidably mounted on the base plate 19. Mounted on slide rail 15, the inner end of lead screw 17 is rotatably connected to mounting platform 14, lead screw 17 is connected to slide table 16 via lead screw nut, slide rail 15 is parallel to lead screw 17, the outer ends of slide rail 15 and lead screw 17 are connected to top plate 18, stepper motor 19 is mounted on top plate 18, the output shaft of stepper motor 19 is connected to lead screw 17, and glue delivery tube 4 is mounted on slide table 16; also includes slide table 23, lifting rod 24, fixed base 25, turntable 26, and turntable The second slide 23 is movably mounted on the base plate 1, the fixed end of the lifting rod 24 is mounted on the second slide 23, the fixed seat 25 is mounted on the top of the piston rod of the lifting rod 24, the first turntable 26 is mounted on the fixed seat 25, the second turntable 27 is concentrically mounted on the end face of the first turntable 26, a locking component is provided between the second turntable 27 and the first turntable 26, the connector 28 is mounted on the second turntable 27, and the connector 28 is provided with a structure for quick assembly and disassembly with the material rack 2.

[0022] During operation, a suitable material rack 2 is selected according to the style of the rubber product. The material rack 2 is connected to the dovetail groove of the connector 28 by a dovetail locking block. Rotating the material rack 2 causes the turntable 27 to flip relative to the turntable 26. At this time, the structure on the material rack 2 that clamps the rubber product faces the same direction, clamping the rubber product onto the lower end face of the material rack 2. The material rack 2 is then flipped so that the rubber product faces downward. After the material rack 2 is adjusted, the locking component locks the turntable 26 and the turntable 27. The piston rod of the lifting rod 24 extends and retracts, causing the rubber product to rise and fall, maintaining a suitable distance between the nozzle 5 and the rubber product. The glue pump 3 operates, conveying glue through the glue delivery pipe to the glue delivery pipe 4. After entering the glue delivery pipe 4, the glue is output through the upper port of the nozzle 5. At the same time, the output shaft of the motor 13 drives the mounting platform 14 to rotate, thereby driving the glue delivery pipe 4 and the nozzle 5 to move circumferentially through the slide rail 15 and the lead screw 17. Stepper motor 19 drives lead screw 17 to rotate. Lead screw 17 drives slide table 16 to move along slide rail 15 through lead screw nut, thereby driving glue delivery tube 4 and glue nozzle 5 to move linearly and adjusting the distance between glue nozzle 5 and mounting platform 14. This drives glue delivery tube 4 to move along the glue application route matched with the rubber product, so that glue nozzle 5 applies glue to the surface of the rubber product, realizing automatic glue application for square and round rubber products. When excess glue drips from the surface of the rubber product, it is caught and collected by glue receiving hopper 6. After the glue application is completed, the rubber product on the lower surface of material rack 2 is removed. The residual glue at the upper end of glue nozzle 5 drips into glue receiving hopper 6 for collection. Compared with the existing technology, the glue application is carried out from bottom to top, and the glue receiving hopper 6 receives and collects the residual glue, avoiding glue dripping and contaminating the platform. Without the obstruction of glue nozzle 5, the rubber product is easier to remove and the unloading is more convenient.

[0023] Example 2

[0024] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, based on Embodiment 1, it further includes a hinge seat 7, a cover plate 8, and a hinge shaft 9. The hinge seat 7 is installed in the glue receiving hopper 6. The lower end of the cover plate 8 is rotatably connected to the hinge seat 7 via the hinge shaft 9. An elastic member is provided between the cover plate 8 and the hinge seat 7. The elastic force of the elastic member causes the upper end of the cover plate 8 to press against the upper port of the glue nozzle 5. It also includes a gear 10, a baffle 11, and a toothed groove 12. A recovery hole is provided at the bottom of the side wall of the glue nozzle 5. The recovery hole communicates with the internal channel of the glue nozzle 5. The gear 10... The device is concentrically mounted on the hinge shaft 9. The baffle 11 is slidably mounted on the outer wall of the nozzle 5. The baffle 11 is provided with a glue inlet hole that matches the recycling hole. The baffle 11 is equipped with a toothed groove 12, which meshes with the gear 10. The device also includes a second motor 20, a bevel gear 21, and a bevel gear ring 22. The second motor 20 is mounted on the slide table 16. The bevel gear 21 is concentrically mounted on the output shaft of the second motor 20. The bevel gear ring 22 is concentrically mounted on the glue delivery pipe 4. The bevel gear 21 meshes with the bevel gear ring 22.

[0025] When no glue is applied, the elastic force of the elastic component causes the upper end of the cover plate 8 to close the upper port of the nozzle 5, further preventing residual glue from overflowing. When applying glue, the upper end of the cover plate 8 is blocked by the rubber product, thus opening the upper port of the nozzle 5 without affecting the glue application process. The glue pump 3 is equipped with a back-pull function, which can draw the residual glue in the glue delivery tube 4 and the nozzle 5 back into the glue tank. When no glue is applied, the upper end of the cover plate 8 closes the upper port of the nozzle 5. At this time, the glue inlet hole of the baffle 11 is aligned with the recovery hole of the nozzle 5. At this time, the back-pull function of the glue pump 3 is activated, and the residual glue collected in the glue receiving hopper 6 is recovered through the recovery hole and the glue inlet hole into the channel of the nozzle 5 for reuse. When applying glue, the cover plate 8 closes the upper port of the nozzle 5. The cover plate 8 is blocked by the rubber product and flips over, causing the lower end of the cover plate 8 to drive the hinge shaft 9 to rotate. The hinge shaft 9 drives the gear 10 to rotate. The gear 10 meshes with the tooth groove 12 and drives the baffle 11 to rise along the outer wall of the nozzle 5, so that the glue inlet hole and the recycling hole are misaligned, and the baffle 11 closes the recycling hole of the nozzle 5. At this time, when the glue pump 3 is running to deliver glue, the glue will not overflow through the recycling hole of the nozzle 5 and the glue inlet hole of the baffle 11. The motor 20 drives the bevel gear 21 to rotate. The bevel gear 21 meshes with the bevel gear ring 22 to drive the glue delivery pipe 4, the nozzle 5 and the glue receiving hopper 6 to rotate, thereby adjusting the upper end of the cover plate 8 to be in the same direction as the nozzle 5, so that the cover plate 8 remains open when applying glue.

[0026] like Figures 1 to 6As shown, this utility model discloses a rubber product coating device. During operation, a suitable material rack 2 is first selected according to the style of the rubber product. The material rack 2 is then installed onto the connector 28. The rubber product is clamped onto the lower end face of the material rack 2. The material rack 2 is flipped, and turntables 27 and 26 are locked. The piston rod of the lifting rod 24 retracts, causing the material rack 2 to descend and approach the upper port of the nozzle 5. The glue pump 3 operates, conveying glue through the glue delivery pipe to the glue delivery pipe 4. After entering the glue delivery pipe 4, the glue is output through the upper port of the nozzle 5. Simultaneously, the output shaft of the motor 13 drives the mounting platform 14 to rotate, thereby causing the glue delivery pipe 4 and nozzle 5 to move circumferentially via the slide rail 15 and the lead screw 17. The stepper motor 19 drives the lead screw 17 to rotate, and the lead screw 17, through the lead screw nut, drives the slide table 16 to move along the slide rail 15. The glue delivery tube 4 and nozzle 5 move linearly, and the distance between nozzle 5 and mounting platform 14 is adjusted so that glue delivery tube 4 moves along the glue application route matching the rubber product. This allows nozzle 5 to apply glue to the surface of the rubber product. When excess glue drips from the surface of the rubber product, it is caught and collected by glue collection hopper 6. During glue application, cover plate 8 is blocked and opened by the rubber product. After glue application is completed, material rack 2 is flipped over, and the rubber product on the lower surface of material rack 2 is removed. Residual glue drips from the upper end of nozzle 5 into glue collection hopper 6 for collection. The upper end of cover plate 8 closes the upper end of nozzle 5. At this time, the glue inlet of baffle 11 is aligned with the recycling hole of nozzle 5. At this time, the back-pull function of glue pump 3 is activated, and the residual glue collected in glue collection hopper 6 is recycled into the channel of nozzle 5 through recycling hole and glue inlet hole for reuse.

[0027] The main functions achieved by this utility model are:

[0028] 1. Apply glue from bottom to top, and collect residual glue through glue receiving hopper 6 to prevent glue dripping and contaminating the platform;

[0029] 2. Without the obstruction of nozzle 5, rubber products are easier to remove and the material is more convenient to unload;
