Description

Technical Field

[0001] The present invention relates to the field of rubber product surface gluing equipment, and specifically to a gluing device for rubber product processing. Background Art

[0002] After the rubber product is processed and formed, glue needs to be applied and covered on its surface for the next rubber product processing operation; the common gluing methods of the current gluing equipment are generally spraying or using a roller for rolling and brushing; The Chinese patent discloses a gluing device for rubber part production (authorized publication number CN221537151U). This patented technology can first spray glue and then send it to the glue spraying component for spraying. After spraying, it is spread evenly by the spreading component. Compared with the prior art, it can effectively remove the adhered dust and improve the bonding quality. However, whether it is the spraying method or the roller rolling and brushing method, the amount of glue cannot be controlled, and the problem of excessive glue use often occurs, resulting in waste of glue. Moreover, using the spraying method is likely to spray the glue outside the rubber product, causing environmental pollution of the working environment. Therefore, the present invention provides a gluing device for rubber product processing to solve the above-mentioned problems. Summary of the Invention

By providing power to the rotating shaft through the second driving motor to drive the moving synchronous belt to move, the moving rack can be driven to reciprocate on the placement rack.

[0006] As a further solution of the present invention, the glue application structure includes a fixing frame. One end of the fixing frame is fixedly connected with a first driving motor, and the other end of the fixing frame is slidably connected with a movable frame. The movable frame can be driven to move up and down by the first driving motor.

The upper end of the glue inlet pipe is fixedly connected with a partition plate, and the partition plate is located inside the chamber. A plurality of flow holes are formed on the outer wall of the glue inlet pipe. The glue in the chamber can be drained into the pressure applying pipe through the flow holes. The pressure applying pipe and the glue discharging ring are connected by a plurality of connecting pipes.

[0008] As a further solution of the present invention, in order to enable the glue discharging ring to smoothly move out of the cylinder body, a plurality of force applying rods are connected to the upper end of the glue discharging ring. The force applying rods are slidably connected with the inner wall of the cylinder body. The upper end of the force applying rod is also rotatably connected with a force generating rod. One end of the force generating rod away from the force applying rod is rotatably connected with the pressure applying pipe.

[0009] As a further solution of the present invention, the lower end of the pressure applying pipe is fixedly connected with a transition pipe. The lower end of the transition pipe is fixedly connected with an inner cylinder for maintaining the state of the glue. The lower end of the inner cylinder is fixedly connected with a top rod.

[0010] As a further solution of the present invention, a heating chamber is also arranged inside the inner cylinder. A pressure pipe is fixedly connected inside the heating chamber. The upper end of the pressure pipe is fixedly connected with a conveying pipe. The conveying pipe sequentially passes through the transition pipe, the pressure applying pipe and the partition plate, and the upper end of the conveying pipe is fixedly connected with a connecting hose for connecting with the glue guiding pipe. A heating piston is slidably connected inside the pressure pipe. The lower end of the heating piston is fixedly connected with a pressure spring for resetting.

[0011] As a further solution of the present invention, the pressure pipe is connected with the heating chamber through exhaust holes. The exhaust holes are provided with two, and a one-way structure is arranged inside the exhaust holes. A connecting channel connected with the outside is also arranged at the lower end inside the pressure pipe. The connecting channel penetrates through the top rod, and a one-way valve is arranged inside the connecting channel. In order to ensure that air can pass through the top rod, a plurality of air inlet grooves are formed on the outer wall of the top rod.

[0012] As a further aspect of the present invention, the one-way structure includes a plug that can slide within the exhaust hole. One end of the plug located inside the exhaust hole is fixedly connected to an elastic spring, and the elastic spring is fixedly connected to the inner wall of the exhaust hole, facilitating the reset of the plug through the elastic spring.

[0013] As a further aspect of the present invention, a glue outlet hole is further formed on the outer wall of the pressure tube. A control tube is fixedly connected within the glue outlet hole.

A pressure relief hole is further formed on the outer wall of the control tube.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the present invention is in use, during the downward movement of the glue application cylinder, when it encounters a rubber product obstruction, the ejector rod will receive an upward force, causing the pressure tube to push the force application rod to drive the force application lever downward, and then the glue outlet ring moves out of the cylinder body to contact the rubber product. During this process, after the glue outlet ring contacts the rubber product under the push of the force application rod, it will deform, causing the glue to flow out through the glue discharge hole and drip onto the surface of the rubber product, thus completing the glue application to the rubber product. Moreover, as the extrusion progresses, the glue outlet ring will cover the glue dripping from the upper end of the rubber product to smear the glue. By this method, the glue can be saved, and the situation of glue waste can be avoided. Since the glue outlet ring is evenly extruded, the glue will be evenly discharged from multiple glue discharge holes, thereby increasing the evenness of glue application.

[0015] 2. When the present invention is in use, the other ejector rods that do not contact the rubber product will enter the docking holes. By this method, multiple glue application cylinders can be used to cover the rubber product, and then glue application can be carried out according to the shape of the rubber product to avoid waste.

[0016] 3. When the present invention is in use, the heating piston can be pushed by the glue to compress the air to heat the inside of the heating chamber, thus preventing the glue in the glue outlet ring and the pressure tube from solidifying and avoiding the blockage of the glue discharge hole.

And a number of rotating wheels 9 are rotatably connected inside the glue - applying table 6. A driving motor for driving the rotating wheels 9 to rotate is also arranged inside the glue - applying table 6; The glue - applying cylinder 10 includes a cylinder body 100. There is also a chamber inside the cylinder body 100. A glue - discharging ring 101 for applying glue is slidably connected inside the cylinder body 100, and the glue - discharging ring 101 is made of copper material. Specifically, the glue - discharging ring 101 is made of a copper sheet with a thickness of 1 millimeter. A ring formed by a 1 - millimeter - thick copper sheet can easily deform when being extruded. A number of glue - discharging holes 102 are opened on the outer wall of the glue - discharging ring 101. The glue - discharging holes 102 are arranged in a downward - inclined shape on the outer wall of the glue - discharging ring 101. Specifically, by arranging the glue - discharging holes 102 in a downward - inclined manner, the glue can be accurately dripped onto the surface of the rubber product. A pressure - applying pipe 106 is also slidably connected inside the cylinder body 100. The upper end of the pressure - applying pipe 106 is fixedly connected to a glue - inlet pipe 107. A return spring is sleeved outside the glue - inlet pipe 107, and the glue - inlet pipe 107 is in communication with the pressure - applying pipe 106. The upper end of the glue - inlet pipe 107 is fixedly connected to a partition plate 108, and the partition plate 108 is located inside the chamber. More specifically, a round hole is opened at the top of the cylinder body 100. The glue - inlet pipe 107 is located in the round hole, and the outer diameter of the glue - inlet pipe 107 is adapted to the inside of the round hole. A number of flow holes are opened on the outer wall of the glue - inlet pipe 107. Through the flow holes, the glue in the chamber can be drained into the pressure - applying pipe 106.

More specifically, a shrinkage pipe 113 is fixedly connected to the connection part of the connecting pipe 112 and the glue - discharging ring 101. Through the shrinkage pipe 113, the moving distance of the glue - discharging ring 101 can be increased; In order to enable the glue - discharging ring 101 to smoothly move out of the cylinder body 100, a number of force - applying rods 110 are connected to the upper end of the glue - discharging ring 101.

The outer diameter of the inner cylinder 104 is the same as the inner diameter of the glue outlet ring 101, that is, the glue outlet ring 101 can slide along the outer wall of the inner cylinder 104, thereby increasing the stability of the glue outlet ring 101. A push rod 119 is fixedly connected to the lower end of the inner cylinder 104, and the push rod 119 corresponds to the docking hole 8. When the push rod 119 moves downward and contacts the rubber product on the upper end of the glue application table 6, it will receive a reverse acting force, so that the inner cylinder 104 drives the pressure application pipe 106 to move upward, and then the glue outlet ring 101 is pushed out to contact the rubber product by the cooperation of the force application rod 111 and the force application rod 110, and then subsequent glue application is carried out; A heating chamber 115 is also arranged inside the inner cylinder 104. A pressure pipe 114 is fixedly connected inside the heating chamber 115. A conveying pipe 124 is fixedly connected to the upper end of the pressure pipe 114.

A heating piston 116 is slidably connected inside the pressure pipe 114, and a pressure spring 117 for resetting is fixedly connected to the lower end of the heating piston 116; The pressure pipe 114 is connected to the heating chamber 115 through exhaust holes 118. Two exhaust holes 118 are provided, and a one-way structure is arranged inside the exhaust holes 118. A connecting channel connected to the outside is also arranged at the lower end inside the pressure pipe 114. The connecting channel penetrates through the push rod 119, and a one-way valve is arranged inside the connecting channel. In order to ensure that air can pass through the push rod 119, a plurality of air intake grooves are opened on the outer wall of the push rod 119; Specifically, please refer to Figure 6 and Figure 8 , the one-way structure includes a plug 125 that can slide inside the exhaust hole 118. A elastic spring 126 is fixedly connected to the end of the plug 125 located inside the exhaust hole 118, and the elastic spring 126 is fixedly connected to the inner wall of the exhaust hole 118. The elastic spring 126 facilitates the reset of the plug 125; More specifically, the one-way valve includes a blocking rod 120 slidably connected inside the connecting channel. A sealing head 123 is fixedly connected to the upper end of the blocking rod 120. The connecting channel can be blocked by the sealing head 123. A limiting disk 121 is also fixedly connected to the outer wall of the blocking rod 120. The sealing head 123 can only move toward the inside of the pressure pipe 114 through the limiting disk 121. A support spring 122 for maintaining sealing is sleeved outside the blocking rod 120; An adhesive outlet hole is also formed in the outer wall of the pressure pipe 114. A control pipe 13 is fixedly connected inside the adhesive outlet hole. One end of the control pipe 13 is fixedly connected with a diversion pipe 14, and the other end is fixedly connected with a drainage pipe 12. The diversion pipe 14 and the drainage pipe 12 are staggered from each other. The upper end of the diversion pipe 14 is fixedly connected with a partition plate 108. An adhesive outlet channel 15 communicating with the chamber is formed inside the partition plate 108. The diversion pipe 14 corresponds to the adhesive outlet channel 15. The lower end of the drainage pipe 12 is fixedly connected with a trigger pipe 11. The trigger pipe 11 corresponds to one of the exhaust holes 118 and is fixedly connected with the outer wall of the pressure pipe 114. A blocking piston 17 and a pressure piston 19 are slidably connected inside the control pipe 13. A connecting rod 18 is fixedly connected between the blocking piston 17 and the pressure piston 19. Two cavities are arranged inside the control pipe 13. The blocking piston 17 and the pressure piston 19 are respectively located in the two cavities. A pressure relief hole 20 is also formed in the outer wall of the control pipe 13. A connecting soft rope is fixedly connected to the inner wall of the control pipe 13 to ensure the stroke of the pressure piston 19. The connecting soft rope is fixedly connected with the pressure piston 19. To ensure that the glue in the pressure application pipe 106 can smoothly flow into the adhesive outlet ring 101, a pressure application pipe 16 is fixedly connected inside the transition pipe 105. The top of the pressure application pipe 16 is located inside the pressure application pipe 106. Specifically, a groove is formed at the inner top end of the pressure application pipe 106. The top end of the pressure application pipe 16 is located inside the groove. The pressure in the temperature rising chamber 115 can be transmitted into the pressure application pipe 106 through the pressure application pipe 16 to promote the flow of the glue.

[0031] The working principle of the present invention is: When the present invention is in use, the rubber product is placed on the conveyor belt 5 and then conveyed to the upper end of the gluing table 6. Then, the first driving motor 304 is started to drive the gluing cylinder 10 to move downward. During the downward movement of the gluing cylinder 10, when it encounters the obstruction of the rubber product, the ejector rod 119 will receive an upward force, so that the pressure tube 106 pushes the force-applying rod 111 to drive the force-applying rod 110 to move downward, and then the glue outlet ring 101 moves out of the cylinder body 100 to contact the rubber product. During this process, after the glue outlet ring 101 contacts the rubber product under the push of the force-applying rod 110, it will deform, and then the glue will flow out through the glue discharge hole 102 and drip onto the surface of the rubber product, thus completing the gluing of the rubber product. Moreover, as the glue outlet ring 101 is extruded, it will cover the glue dripping from the upper end of the rubber product, thereby smearing the glue. By this method, the glue can be saved, and the situation of glue waste can be avoided. Since the glue outlet ring 101 is evenly extruded, the glue will be evenly discharged from multiple glue discharge holes 102, so as to increase the evenness of glue smearing. Moreover, the other ejector rods 119 that do not contact the rubber product will enter the docking hole 8. By this method, multiple gluing cylinders 10 can be used to cover the rubber product, and then gluing can be carried out according to the shape of the rubber product to avoid waste. When the gluing is completed, the gluing cylinder 10 moves upward. At this time, under the action of the return spring outside the glue inlet pipe 107, the pressure tube 106 will reset, so that the glue outlet ring 101 is retracted into the cylinder body 100 again; When the present invention is started, the glue will enter the pressure tube 114 through the connecting hose 109 and the conveying tube 124. The glue entering the pressure tube 114 will push the heating piston 116 to compress the pressure spring 117, thereby compressing the air in the pressure tube 114. The air in the pressure tube 114 will heat up after being compressed. When the pressure in the pressure tube 114 reaches the pulling limit of the elastic spring 126, the plug 125 will release the blockage of the exhaust hole 118, and then the high-pressure gas with temperature in the pressure tube 114 will be discharged into the heating chamber 115. At this time, the glue will stop flowing into the pressure tube 114 (it should be noted that the transportation of the glue into the pressure tube 114 is intermittent and will stop when it reaches the time, and at this time, the exhaust hole 118 is just opened. This operation is completed in the PLC controller and is precisely controlled by the PLC program). When the pressure in the pressure tube 114 is released, the pressure spring 117 will push the heating piston 116 to reset. At this time, a negative pressure will be generated below the heating piston 116 in the pressure tube 114, so that the plug head 123 will release the blockage of the connecting channel, allowing the outside air to enter the pressure tube 114, and then normal-temperature air will enter the pressure tube 114; While the heating piston 116 moves upward, it will push the glue upward. At this time, the glue will push against the blocking piston 17, and some of the air in the pressure pipe 114 will also enter the control pipe 13 through the trigger pipe 11 and the drainage pipe 12, and then push the pressure piston 19 to pull the blocking piston 17 to move, so that the blocking piston 17 contacts the blocking of the diversion pipe 14, allowing the glue in the pressure pipe 114 to flow into the chamber along the diversion pipe 14 for temporary storage. When the ejector rod 119 is pushed up next time, the glue in the chamber will flow into the pressure application pipe 106 through the glue inlet pipe 107, and then flow into the glue outlet ring 101. By repeating this cycle, the glue can be used as power to generate high-temperature gas in the pressure pipe 114 to increase the temperature in the heating chamber 115, heating the entire cylinder 100 and the glue outlet ring 101 to prevent the glue from solidifying; After the elastic force of the pressure spring 117 is released, the air in the control pipe 13 will discharge from the pressure relief hole 20, and the pressure piston 19 and the blocking piston 17 will reset (specifically, there is a certain pressure between the pressure piston 19 and the control pipe 13 to push the pressure piston 19 and the blocking piston 17), thus preparing for the next cycle; The rubber products coated with glue will be sent to the discharge plate 7 under the rotation of the rotating wheel 9, and then move along the discharge plate 7 to the designated position to complete glue coating.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
