Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing, in particular to a quantitative glue spraying device for rubber processing. Background Art

[0002] Rubber is a highly elastic polymer material, which can be divided into artificial rubber and natural rubber. Natural rubber is obtained from the sap of some plants. Because of its good elasticity, mechanical equipment often uses rubber pads for buffering to activate the protective function. During the processing and production of rubber pads, it is necessary to spray glue on the joints to fix them.

[0003] When spraying glue on the rubber pad, the existing glue spraying equipment takes the processing table as the main body, and a support frame is set on the top side of the processing table, a spray gun is set on the bottom side of the support frame, and an air pump is set on the bottom side of the processing table. A storage tank is set on one side of the air pump, and glue is stored in the tank. A centrifugal pump is fixedly installed on the bottom side of the processing table, and its input end is connected to the storage tank, and the output end is connected to the spray gun. The output end of the air pump is connected to the spray gun through a conduit. The rubber sheet is placed on the top side of the processing table, and the air pump and the centrifugal pump are turned on. The centrifugal pump transports the glue to the spray gun. The high-pressure air transported by the air pump drives the glue to be sprayed onto the surface of the rubber sheet, thereby bonding the multiple layers of rubber. The structure is simple and practical, and convenient for operators to use.

[0004] However, when the current glue spraying equipment is spraying glue, the glue spraying amount of the spray gun is controlled only by controlling the start and stop of the pump, which causes quality problems at the rubber adhesion due to too much or too little glue, resulting in a decrease in the quality of the rubber spraying processing. Therefore, a rubber processing glue spraying quantitative device is proposed. Utility Model Content

[0011] 1. The utility model adopts a structural design of a quantitative glue spraying device for rubber processing. By setting a quantitative mechanism, when performing glue spraying processing, the cylinder is controlled to shrink the inner round rod, thereby driving the piston to slide inside the tank body.

At this time, with the cooperation of the one-way valve at the input port 8, the glue on the inside of the box body 10 is drawn into the inside of the tank body 3 by the input pipe 9, and then the cylinder 5 is controlled to extend the inner round rod 6, thereby driving the piston 4 to slide in the opposite direction on the inside of the tank body 3, so that with the cooperation of the one-way valve at the output port 7, the glue is transported to the inside of the storage tank 12 through the output pipe 11, and then sprayed out by the atomizing nozzle 13, thereby ensuring that the glue spraying amount is the same each time to realize the function of quantitative glue spraying.

[0023] See also Figure 3 As shown, the lifting mechanism includes a positioning rod 14, and the side of the positioning rod 14 is evenly provided with positioning holes 15.

[0026] Working principle: rubber is a highly elastic polymer material, which can be divided into artificial rubber and natural rubber. Natural rubber is obtained from the sap of some plants. Because of its good elasticity, mechanical equipment often uses rubber pads for buffering to start the protection function. During the processing and production of rubber pads, it is necessary to spray glue at the joints to make them fixedly connected. When the existing glue spraying equipment sprays glue, it only controls the start and stop of the pump to control the amount of glue sprayed by the spray gun, so that the rubber adhesion has quality problems due to too much or too little glue, resulting in a decrease in the quality of rubber spraying processing. In order to solve this problem, a quantitative mechanism and a lifting mechanism are set to place the rubber sheet on the inner side of the limit block 22, and the rubber sheet is fitted with the air hole 21 on the surface of the processing table 1.

At this time, the spring 17 supports the sleeve 16 to prevent it from contacting with the desktop The sleeve 16 is then pushed to slide on the positioning rod 14 to a suitable height. At this time, the insertion rod 18 passes through the sleeve 16 and is re-inserted into the inner side of the positioning hole 15 to fix the position of the sleeve 16. At this time, the atomizing nozzle 13 fixed on the support rod 19 is fixed at the required height. Finally, the cylinder 5 is controlled to shrink the inner round rod 6, thereby driving the piston 4 to slide inside the tank body 3. At this time, with the cooperation of the one-way valve at the input port 8, the input pipe 9 draws the glue inside the box body 10 into the inner side of the tank body 3, and then the cylinder 5 is controlled to The inner round rod 6 is extended, thereby driving the piston 4 to slide in the opposite direction inside the tank body 3, so that with the cooperation of the one-way valve at the output port 7, the glue is transported to the inside of the storage tank 12 through the output pipe 11, and then sprayed out by the atomizing nozzle 13, and a certain amount of glue is evenly sprayed to the adhesion position of the rubber sheet, and then it is adhered to other rubber sheets, and the air pump 23 is turned off to release the fixation of the rubber sheet, and it is taken out to complete the processing, which solves the problem that the existing glue spraying equipment cannot accurately control the glue spraying amount, resulting in a decrease in the quality of rubber spraying processing.
