Description

Technical Field

[0001] The invention belongs to the technical field of rubber product coating, in particular to a device and method for manufacturing coated rubber products. Background Art

[0002] Rubber product production refers to the activity of producing various rubber products using natural and synthetic rubber as raw materials. At the same time, rubber product production also includes the operation of reproducing rubber products using waste rubber. After the rubber products are processed and formed, they need to be covered with glue on their surface in order to carry out the subsequent rubber product reprocessing operations.

[0003] A patent with publication number CN117563871A discloses a rubber product gluing device; the rubber product gluing device comprises: a base, a feed belt is movably installed on the upper end of the base, and an output mechanism is provided on the inner side of the feed belt; a gluing mechanism is installed at the middle upper end of the feed belt, and the gluing mechanism comprises a gluing roller and a guide roller; the rubber product gluing device covers the glue used for coating in the inner material layer with an outer protective film, when the guide roller rotates, the outer protective film can be torn off for centralized collection, and when the gluing roller rotates, the glue can be squeezed and evenly coated on the upper surface of the rubber product; therefore, there is no need to design a glue temporary storage cylinder and to add a stirring component and a heating resistor wire inside the glue temporary storage cylinder; in addition, there is no need to design a robotic arm to control the spray angle of the high-pressure nozzle, and there is no need to design a computer operating program adapted to the robotic arm, thereby reducing the application cost of the entire rubber product gluing device.

[0004] In the current prior art, when the existing rubber products are coated with glue, the rubber products are manually sprayed with glue using a spray gun. However, this results in the inability of the manual spray gun to completely coat the rubber products with glue, and it is necessary to repeatedly spray glue on some gaps or narrow places. Under repeated spraying, the remaining positions of the rubber products will cause repeated spraying of glue, resulting in the problem of excessive thickness in the repeated spraying positions, and the manual spraying of glue cannot shake off and clean the coated glue at the thicker positions, which leads to the problem of inconsistent or excessively thick coated glue thickness on the surface of the rubber products.

[0005] To this end, the present invention provides an apparatus and method for manufacturing a coated rubber product. Summary of the invention

When the rubber product rotates inside the liquid-throwing cylinder, the inside of the suction pipe ring is evacuated by a vacuum pump, so that some waste gas accumulated inside the liquid-throwing cylinder is recovered, and then the recovered waste gas is re-injected into the inside of the spray coating tank through the guide air pipe, thereby achieving a gas circulation formed by gas flow, which can greatly avoid the leakage of the coating gas inside the spray coating tank.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Example 1

[0034] like Figures 1 to 7As shown, a device for manufacturing coated rubber products according to an embodiment of the present invention comprises a support casing 11 and a glue spray coating tank 12 arranged at the bottom edge position of the support casing 11, a slider 13 movably overlapped on the outer surface of the top of the support casing 11, a rubber product 14 movably overlapped on the outer surface of the support casing 11, an air intake pipe ring 15 detachably mounted on the outer surface of the top of the support casing 11, a hydraulic rod 112 is arranged on the top surface of the support casing 11, a motor 115 is fixedly mounted on the output end of the hydraulic rod 112, and a clamping extruder 113 detachably mounted on the outer surface of the rubber product 14 is fixedly connected to the output end of the motor 115; a liquid-throwing cylinder 122 arranged on the outer surface of the bottom of the support casing 11 is fixedly mounted on the top surface of the glue spray coating tank 12, a closing plate 152 is arranged on the top surface of the liquid-throwing cylinder 122 and located at the top edge position of the air intake pipe ring 15, and glue spray heads 121 are fixedly mounted on the inner wall surfaces on both sides of the glue spray coating tank 12.

[0035] The surface of the rubber product 14 is clamped by the clamping extruder 113, and at the same time, the hydraulic rod 111 is cooperated with the hydraulic rod 2 112 to lower and the hydraulic rod 2 112 is extended to the clamping extruder 113, so that the rubber product 14 moves into the interior of the glue spray coating tank 12, and then is closed by the closing plate 152, so that the two closing plates 152 are docked on the outer surface of the output end of the motor 115, so that the inside of the glue spray coating tank 12 and the liquid-spinning cylinder 122 are in a closed state, and at this time, the glue spraying head 121 is cooperated to spray glue on the two sides of the rubber product 14. At this time, the rubber product 14 is slowly rotated by the motor 115, so that the glue spraying head 121 performs multi-directional and multi-angle glue spraying on the surface of the rubber product 14. After the surface of the rubber product 14 is coated with glue, the hydraulic rod 2 112 is cooperated to lift the rubber product 14, so that the rubber product 14 moves up to the interior of the liquid-spinning cylinder 122, and at this time, the motor 115 is cooperated to The rubber product 14 rotates at a high speed, so that the excess coating liquid on the surface of the rubber product 14 adheres to the inner wall surface of the liquid-spinning cylinder 122 under the swinging of centrifugal force. At the same time, the coating liquid on the inner wall surface of the liquid-spinning cylinder 122 will drip down under its own gravity and then the excess coating liquid will be recovered, so that the coating liquid swung out of the rubber product 14 by the liquid-spinning cylinder 122 is recovered. At the same time, the liquid-spinning cylinder 122 is located at the center position of the top of the glue spraying coating tank 12, and the dripping coating liquid will not re-attach to the surface of the output hole of the glue spraying head 121, thereby avoiding the motor 115 from coating the inside of the glue spraying coating tank 12, and rotating at a high speed inside the glue spraying coating tank 12 to swing out the excess coating liquid on the surface of the rubber product 14, and the splashed coating liquid will re-attach to the surface of the output hole of the glue spraying head 121, thereby causing the output hole of the glue spraying head 121 to be blocked due to the drying of the external coating liquid.

[0036] like Figure 1 - Figure 4 and Figure 7 As shown, a swing plate 132 is swingably connected to one side surface of the slider 13, an elastic wire 131 arranged on one side surface of the swing plate 132 is fixedly connected to the bottom surface of the slider 13, a lock buckle 133 is arranged on one side surface of the slider 13 and at the two side edge positions of the swing plate 132, a limit strip 134 is symmetrically fixedly connected to the two side inner wall surfaces of the slider 13, a hydraulic push rod 135 is fixedly installed on the top surface of the slider 13 and at the other side edge position, a pushing plate 136 movably overlapped on the surfaces of the slider 13 and the limit strip 134 is fixedly connected to the output end of the hydraulic push rod 135, a squeezing soft strip 137 is fixedly connected to one side surface of the pushing plate 136, a fitting anti-skid plate 138 movably sleeved on the outer surface of the slider 13 and the limit strip 134 is fixedly connected to the other end surface of the squeezing soft strip 137, and a fitting anti-skid plate 138 movably sleeved on the outer surface of the slider 13 and the limit strip 134 is fixedly connected to the other end surface of the squeezing soft strip 137, and the fitting anti-skid plate 138 and one side surface of the swing plate 132 are movably fitted to the two side surfaces of the rubber product 14.

[0037] Under the swinging of the motor 115, after the excess coating liquid on the surface of the rubber product 14 is cleaned, the rubber product 14 is lifted up by the hydraulic rod 111 and then pulled out from the inside of the liquid-spinning cylinder 122. At this time, the slider 13 slides on the top surface of the limiting platform 114, and then moves the slider 13 to the bottom surface of the rubber product 14. When the swing plate 132 contacts the surface of the rubber product 14, the swing plate 132 swings on the surface of the slider 13 under the continuous push of the slider 13, so that the swing plate 132 bends. When the swing plate 132 passes over the bottom surface of the rubber product 14, the elastic pull of the elastic wire 131 makes the swing plate 13 2 is reset. After the reset, the swing plate 132 is limited and fixed by the lock 133, so that the other side surface of the swing plate 132 is attached to the surface of the rubber product 14. At this time, the push plate 136 is pushed by the push plate 136, so that the fitting anti-slip plate 138 on the side surface of the push plate 136 is attached to and pressed on the surface of the rubber product 14, and then the two side surfaces of the bottom of the rubber product 14 are attached. When a section of the surface of the rubber product 14 is limited, the clamping squeezer 113 is cooperated to relax, and the slider 13 is pulled back to make the rubber product 14 peeled off from the surface of 113, and then the rubber product 14 is replaced.

[0038] like Figures 1 to 6As shown, an air pump 151 is symmetrically fixedly installed on the two side surfaces of one side of the suction pipe ring 15, and a guide air pipe 153 that passes through the spray coating tank 12 and the surface of the support sleeve 11 is fixedly installed on the output end of the air pump 151. A hydraulic rod 111 is fixedly installed on the top surface of the support sleeve 11, and the output end of the hydraulic rod 111 is fixedly installed on the outer surface of the hydraulic rod 2 112. A limiting platform 114 is fixedly installed on the top surface of the support sleeve 11 and at the edge position of one side, and the bottom surface of the slider 13 is movably fitted on the top surface of the limiting platform 114.

[0039] When the rubber product 14 rotates inside the liquid-throwing cylinder 122, the vacuum pump 151 is used to evacuate the inside of the suction pipe ring 15, so that some of the waste gas accumulated inside the liquid-throwing cylinder 122 is recovered, and then the recovered waste gas is re-injected into the spray coating tank 12 through the guide air pipe 153, thereby achieving a gas circulation formed by gas flow, which can greatly avoid the leakage of the coating gas inside the spray coating tank 12, and avoid the traditional rubber product 14. When the rubber product 14 is sprayed with paint and coated with glue, a large amount of glue gas will be accumulated around the rubber product 14, so that when the rubber product 14 is taken out, the gas around the rubber product 14 will be driven to flow, and then the glue gas in the air will be carried out together, which will cause harm to the surrounding employees and the environment.

[0040] Example 2

[0041] like Figure 8 As shown, a method for manufacturing a coated rubber product comprises the following steps:

[0042] S1. Clamp the top surface of the rubber product and lower the rubber product into the glue spraying device through the hydraulic lifting device;

[0043] S2, spraying glue on the surface of the rubber product by means of a glue spraying device, and then rotating the rubber product by means of a rotating device, so that the glue spraying device can spray glue on the rubber product in all directions;

[0044] S3, the rubber product is moved upward into the liquid-spinning cylinder by the lifting device, and the excess rubber liquid on the surface of the rubber product is spun out by the rotating device;

[0045] S4. After the excess glue is thrown away, the rubber product is positioned with the help of the clamping and positioning device, and then the rubber product is peeled off from the surface of the clamping device by the pulling device, and the rubber product covered with glue is collected and recycled.

[0046] Working principle: cooperate with the clamping extruder 113 to clamp the surface of the rubber product 14, and cooperate with the hydraulic rod 111 to lower the hydraulic rod 2 112 and the hydraulic rod 2 112 to extend the clamping extruder 113, so that the rubber product 14 moves into the inside of the glue spray coating tank 12, and then closes through the closing plate 152, so that the two closing plates 152 are docked on the outer surface of the output end of the motor 115, so that the inside of the glue spray coating tank 12 and the liquid throwing cylinder 122 are in a closed state, and at this time, cooperate with the glue spray head 121 to spray glue on the two sides of the rubber product 14. At this time, the rubber product 14 is slowly rotated by the motor 115, so that the glue spray head 121 sprays glue on the surface of the rubber product 14 in multiple directions and angles, and waits until the rubber After the surface coating of the product 14 is completed, the rubber product 14 is lifted up by the hydraulic rod 112, so that the rubber product 14 moves up to the inside of the liquid-spinning cylinder 122. At this time, the rubber product 14 is rotated at a high speed by the motor 115, so that the excess coating liquid on the surface of the rubber product 14 adheres to the inner wall surface of the liquid-spinning cylinder 122 under the swinging of centrifugal force. At the same time, the coating liquid on the inner wall surface of the liquid-spinning cylinder 122 will drip down under its own gravity, and then the excess coating liquid is recovered, so that the coating liquid swung out of the rubber product 14 by the liquid-spinning cylinder 122 is recovered. At the same time, the liquid-spinning cylinder 122 is located at the center of the top of the glue spraying tank 12, and the dripping coating liquid will not re-attach to the surface of the output hole of the glue spraying head 121;

[0047] Under the swinging of the motor 115, after the excess glue coating on the surface of the rubber product 14 is cleaned, the hydraulic rod 111 is used to lift the rubber product 14 and then pull it out from the inside of the liquid-spinning cylinder 122. At this time, the slider 13 is used to slide on the top surface of the limiting platform 114, and then the slider 13 is moved to the bottom surface of the rubber product 14. When the swing plate 132 contacts the surface of the rubber product 14, under the continuous push of the slider 13, the swing plate 132 will swing on the surface of the slider 13, so that the swing plate 132 bends. After the swing plate 132 passes over the bottom surface of the rubber product 14, the elastic pull of the elastic wire 131 is used to reset the swing plate 132. After resetting, the swing plate 132 is limited and fixed to the position of the swing plate 132 by the lock buckle 133, so that the other side surface of the swing plate 132 is attached to the surface of the rubber product 14. At this time, the push plate 136 pushes the push plate 136, so that the fitting anti-slip plate 138 on the surface of one side of the push plate 136 fits and squeezes on the surface of the rubber product 14, and then fits the bottom two side surfaces of the rubber product 14. When a section of the surface of the rubber product 14 is limited, it is relaxed in cooperation with the clamping squeezer 113, and the slider 13 is pulled back to make the rubber product 14 peel off from the surface of 113, and then the rubber product 14 is replaced; when the rubber product 14 rotates inside the liquid-throwing cylinder 122, the inside of the suction pipe ring 15 is evacuated in cooperation with the vacuum pump 151, so that some waste gas accumulated inside the liquid-throwing cylinder 122 is recovered, and then the recovered waste gas is re-injected into the inside of the spray coating tank 12 through the guide air pipe 153, thereby achieving a gas circulation formed by gas flow, which can greatly avoid the leakage of the glue-coated gas inside the spray coating tank 12.
