Description

Technical Field

[0001] This invention relates to the field of thermal insulation cotton, specifically a thermal insulation cotton production feeding device. Background Technology

[0002] Thermal insulation cotton is a material that provides thermal insulation. It is characterized by high temperature resistance, non-flammability, and low thermal conductivity. It is now widely used in industry and daily life. In industrial applications, it is used to insulate various tanks or pipeline systems. In daily life applications, it is used for building walls or roofs to reduce the efficiency of heat exchange between indoors and outdoors.

[0003] In practical applications, thermal insulation cotton can be designed into various types of insulation materials based on specific needs. When laying insulation materials on roofs, these cotton-based materials require a certain strength to withstand downward pressure. Therefore, reinforcing fabric is attached to the surface of the cotton substrate. Common reinforcing fabric is silicone fireproof cloth. The cotton substrate and reinforcing fabric are typically bonded together with epoxy resin adhesive. Current bonding methods involve pre-laying multiple sheets of insulation cotton, spraying adhesive onto the surface, and then attaching the reinforcing fabric one by one. This method has several drawbacks. First, laying multiple sheets of insulation cotton takes up space. Second, the adhesive is exposed to the air for extended periods, causing air pollution. Third, delayed attachment of the reinforcing fabric can compromise the bond strength between the reinforcing fabric and the insulation cotton.

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] Reference Figure 1 - Figure 8 A heat insulation cotton production feeding device includes two symmetrically arranged transfer units, a gripping unit on one side of the middle of the two transfer units, a conveying component on one side of the gripping unit, and a glue spraying component on one side of the conveying component.

[0037] The two transfer units are used to transfer the heat insulation cotton substrate and the reinforcing fabric attached to the heat insulation cotton substrate, respectively; the gripping unit grips the heat insulation cotton substrate and the reinforcing fabric in sequence, and the gripping unit is also equipped with a pressure regulating component, which is used to control the formation of a negative pressure environment; the glue spraying component is used to spray glue onto the heat insulation cotton substrate, and the conveying component is used to convey the heat insulation cotton substrate and the reinforcing fabric attached together;

[0038] In this embodiment, two transfer units are designed to transfer the insulation cotton substrate and the reinforcing fabric respectively. Workers only need to lay the insulation cotton substrate and the reinforcing fabric one by one on one side of the two transfer units. Workers do not need to move their positions, reducing walking and labor costs. At the same time, the circumferential transfer of the transfer units avoids the problem of the insulation cotton substrate occupying space. The gripping component picks up the insulation cotton substrate and the reinforcing fabric in sequence and lays them on the conveying component. The insulation cotton substrate is laid on the conveying component first, and then the glue spraying component sprays glue on its surface. During the glue spraying process, the gripping unit picks up and transfers the reinforcing fabric. After the glue spraying is completed, the reinforcing fabric is transferred on top of the insulation cotton substrate. The reinforcing fabric is laid before the glue dries, ensuring a strong adhesive bond between the insulation cotton substrate and the reinforcing fabric.

[0039] Reference Figure 1 - Figure 7 Each of the transfer units includes a transfer component and a pusher component; each of the transfer components includes a rotatable disc 1, which is through the middle of the disc 1, and a recess 2 is formed at the edge of the upper surface of each disc 1. A sliding hole 3 is formed on the rear side wall of each recess 2, and a pusher component is provided in the recess 2.

[0040] The pushing assembly includes a tray 4, which can slide within the recess 2. The rear end of the tray 4 is fixedly connected to a feeding rod 5, which slides through a sliding hole 3 and extends to the middle position of the tray body 1. The end of the feeding rod 5 is connected to the inner ring side wall of the tray body 1 via a spring. An electric push rod 6 is located in the middle of the tray body 1, with its output end pointing towards the middle position between the two tray bodies 1. A gripping assembly is located on one side of the middle position between the two tray bodies 1. A toothed ring can be provided on the lower surface edge of the tray body 1, which is driven intermittently by an external motor. The heat insulation cotton substrate and reinforcing fabric are stacked on the outside of the tray body 1. Workers lay the heat insulation cotton substrate and reinforcing fabric one by one on the tray 4. Then, the tray body 1 is rotated to the opposite position of the two tray bodies 1. Then, the electric push rod 6 pushes the feeding rod 5, which in turn moves the tray 4. At this time, the heat insulation cotton substrate is laid on the tray 4 and pushed to the position between the two tray bodies 1. Then, the gripping unit picks up the insulation cotton substrate at this position and transfers it to the conveying assembly. Under the control of the pressure regulating assembly, the negative pressure environment for gripping the insulation cotton substrate is broken, and the insulation cotton substrate falls smoothly onto the conveying assembly. Next, the glue spraying assembly sprays glue onto the insulation cotton substrate, while simultaneously pushing the electric push rod 6 of tray 4 to reset. Tray 4 also moves backward into the recess 2 under the elastic force of spring 1, and the tray 1 rotates. At the same time, the electric push rod 6 on the inner ring of the other tray 1 pushes tray 4 to the position between the two trays 1, that is, the reinforcing fabric is pushed out. Then, the gripping unit picks up the reinforcing fabric and transfers it to the insulation cotton substrate sprayed with glue. Under the control of the pressure regulating assembly, the negative pressure environment for gripping the reinforcing fabric is broken, and the reinforcing fabric falls smoothly onto the insulation cotton substrate. Then, the conveying assembly conveys the attached insulation cotton substrate and reinforcing fabric away. Then, the above actions are repeated, and the cycle continues.

[0041] Reference Figure 1 - Figure 8 The gripping component includes a base 7, a driving component is provided on the base 7, and multiple sets of gripping tubes 8 are connected to the driving component. Two gripping tubes 8 in each set are arranged opposite to each other. One end of each gripping tube 8 is connected to the driving component, and the other end of the gripping tube 8 extends outward. A spring 2 is fixedly connected to the other end of the gripping tube 8. An inclined tube 10 is fixedly connected to the end of the spring 2. A right-angle tube is connected to the end of the inclined tube 10. A suction cup 12 with the same shape as the heat insulation cotton substrate is fixedly connected to the vertical end of the right-angle tube 11.

[0042] An arc-shaped pressure rod 13 is provided above the two disc bodies 1. The pressure rod 13 can press down the horizontal end of the right-angle tube 11, so that the suction cup 12 moves down to adsorb the heat insulation cotton substrate and the reinforcing fabric.

[0043] The gripping tube 8 and the inclined tube 10 are connected by a flexible hose, which is positioned within the inner ring of the second spring. The drive assembly can consist of a motor-driven reducer, which can drive the gripping tube 8 to perform intermittent circular motion. When the right-angle tube 11 moves to the position between the two discs 1, under the downward pressure constraint of the pressure rod 13, the suction cup 12 approaches the material on the tray 4, that is, the suction cup 12 adsorbs the heat insulation cotton substrate or reinforcing fabric. When the right-angle tube 11 rotates again and passes the pressure rod 13, the right-angle tube 11 loses the downward pressure of the pressure rod 13, and the inclined tube 10 swings upward to reset under the elastic force of the second spring it is connected to, and then transfers the heat insulation cotton substrate or reinforcing fabric to the conveying assembly. The cooperative design of the inclined tube 10 and the right-angle tube 11 with the pressure rod 13 allows the suction cup 12 to easily adsorb the heat insulation cotton substrate or reinforcing fabric on the tray 4, so as to avoid misalignment and inaccurate adsorption between the suction cup 12 and the material.

[0044] Reference Figure 1 , Figure 2 and Figure 6 The conveying assembly includes a conveyor belt 14, which conveys the thermal insulation substrate and reinforcing fabric attached together. A glue spraying assembly is located on one side of the conveyor belt 14. The glue spraying assembly includes a cylinder 15, the output end of which is fixedly connected to a plate 16. Multiple nozzles are located on the lower surface of the plate 16, and these nozzles are connected to an external pump via material pipes. The cylinder 15 can push the plate 16 to the upper surface of the thermal insulation substrate. The conveyor belt 14 can rotate intermittently, meaning the reinforcing fabric is attached to the thermal insulation substrate... Afterwards, the conveyor belt 14 transports the material and then pauses. After the insulation cotton substrate is transferred onto the conveyor belt 14, as the extension rod rotates away from the conveyor belt 14, the cylinder 15 pushes the plate 16 to move above the insulation cotton substrate. Then, the external pump sprays glue onto the surface of the insulation cotton substrate. After the glue spraying is finished, the cylinder 15 drives the plate 16 to retract and reset. At this time, the suction cup 12 transfers the reinforcing fabric. Under the control of the pressure regulating component, the suction cup 12 loses the negative pressure environment, and the reinforcing fabric falls onto the surface of the insulation cotton substrate.

[0045] Reference Figure 2 , Figure 3 and Figure 7 Each of the recesses 2 has multiple ventilation holes 17 on its inner surface, the ventilation holes 17 extend to the lower surface of the disc body 1, and the lower surface of the disc body 1 is provided with a ring-shaped negative pressure cover 18, the upper surface of the negative pressure cover 18 being close to the lower surface of the disc body 1.

[0046] Multiple adsorption holes 19 are provided on the tray 4, which are set through the tray 4. The tray 4 is located in the recess 2. The adsorption holes 19 correspond one-to-one with the vent holes 17. The negative pressure cover 18 is connected to the external negative pressure pump. The inside of the negative pressure cover 18 is always in a negative pressure environment, and the rotation of the tray 1 will not interfere with the negative pressure cover 18. That is, the tray 1 can rotate normally. At the same time, the vent holes 17 can also be connected to the negative pressure cover 18. When the tray 4 is located in the recess 2, the vent holes 17 are connected to the adsorption holes 19. The negative pressure of the adsorption holes 19 can adsorb the material in the tray 4, that is, adsorb the heat insulation cotton substrate or the reinforcing fabric, so as to prevent the heat insulation cotton substrate or the reinforcing fabric from being thrown off the tray 4 when the tray 1 rotates.

[0047] Reference Figure 2 and Figure 8 Each of the gripping tubes 8 is disconnected at the middle position, and a pressure regulating component is provided at the disconnected position; the pressure regulating component includes a base block 20, with a through horizontal hole 21 and a vertical hole 22 perpendicular to the horizontal hole 21 inside the base shell; a pressure regulating rod 23 is slidably sealed inside the vertical hole 22, with an air passage 24 in the middle position of the pressure regulating rod 23, and an L-shaped vent hole 25 below the air passage 24; the upper half of the pressure regulating rod 23 is slidably connected to the vertical hole 22 by a compression spring;

[0048] The upper end of the pressure regulating rod 23 is provided with an arc-shaped compression spring 26, and the compression spring is positioned above the pressure regulating rod 23 near the conveyor belt 14. The compression spring 26 can compress the pressure regulating rod 23 downwards. The output end of the drive component, i.e., the output end of the reducer in this embodiment, is fixedly connected to an intermediate tube. A ring body rotates on the intermediate tube and is connected to it. The ring body can be connected to an external negative pressure pump body. The intermediate tube is connected to the gripping tube 8. The pressure regulating component controls the formation of the negative pressure environment of the suction cup 12. When the gripping tube 8 rotates to a position relative to the conveyor belt 14, the upper end of the pressure regulating rod 23 interferes with the compression spring 26, that is, the compression spring... 26. Press down the pressure regulating rod 23. The vent hole 25 in the lower half of the pressure regulating rod 23 extends to the bottom of the base block 20. At this time, the suction force of the suction cup 12 connected to the gripping tube 8 decreases and is insufficient to hold the material. That is, the suction cup 12 cannot hold the heat insulation cotton substrate or the reinforcing fabric, ensuring that the heat insulation cotton substrate or the reinforcing fabric falls smoothly. The gripping tube 8 continues to rotate, and the pressure regulating rod 23 loses the pressure of the squeezing spring 26. The pressure regulating rod 23 moves upward under the elastic force of the compression spring connected to it. At this time, the vent hole 25 is blocked, and the air passage 24 is connected to the gripping tube 8 normally again. The suction cup 12 also restores the suction force to hold the material.

[0049] Reference Figure 8 A rubber plate 27 is provided on the inner wall of the lower half of each vertical hole 22. The rubber plate 27 is arranged opposite to the horizontal port of the vent hole 25. The rubber plate 27 is provided to ensure the sealing between the vent hole 25 and the inner wall of the vertical hole 22, and to ensure the stability of the adsorption of materials by the suction cup 12.

[0050] Reference Figure 2 Each right-angle tube 11 is rotatably connected to a roller body 28 at the middle position of its horizontal end. The roller body 28 is recessed in the middle. The roller body 28 is provided to convert the rotational friction between the right-angle tube 11 and the pressure rod 13 into rolling friction between the roller body 28 and the pressure rod 13, thereby reducing friction and wear.

[0051] Reference Figure 6 and Figure 7 Each end of the feeding rod 5 and the end of the electric push rod 6 are fixed with an arc-shaped push plate 29; the push plate 29 is provided to increase the contact area between the electric push rod 6 and the end of the feeding rod 5, so that the electric push rod 6 can stably press against the feeding rod 5, ensuring that the feeding rod 5 pushes the tray 4 away from the recess 2.

[0052] Reference Figure 4 and Figure 5 The upper end face of the pressure regulating rod 23 is provided with a circular plate 30; the circular plate 30 allows the upper end of the pressure regulating rod 23 to slide smoothly in contact with the extrusion spring 26, ensuring that the pressure regulating rod 23 can move down stably and smoothly, so that the suction cup 12 can smoothly reduce the adsorption force.

[0053] Working principle: In this embodiment, two transfer units are designed to transfer the heat insulation cotton substrate and the reinforcing fabric respectively. Workers only need to lay the heat insulation cotton substrate and the reinforcing fabric one by one on one side of the two transfer units. Workers do not need to move their positions, reducing walking and labor. At the same time, the circumferential transfer of the transfer units avoids the problem of the heat insulation cotton substrate occupying area. The gripping component picks up the heat insulation cotton substrate and the reinforcing fabric in sequence and lays them on the conveying component. The heat insulation cotton substrate is laid on the conveying component first, and then the glue spraying component sprays glue on its surface. During the glue spraying process, the gripping unit picks up and transfers the reinforcing fabric. After the glue spraying is completed, the reinforcing fabric is transferred on top of the heat insulation cotton substrate. Before the glue dries, the reinforcing fabric is laid to ensure the strong adhesion between the heat insulation cotton substrate and the reinforcing fabric.

[0054] The thermal insulation substrate and reinforcing fabric are stacked on the outside of the tray 1. Workers lay the thermal insulation substrate and reinforcing fabric one by one on the tray 4. Then, the tray 1 is rotated until it is in a relative position between the two trays 1. Then, the electric push rod 6 pushes the feeding rod 5, which moves the tray 4. At this time, the thermal insulation substrate is laid on the tray 4 and pushed to the position between the two trays 1. Then, the gripping unit grips the thermal insulation substrate at this position and transfers it to the conveying assembly. Under the control of the pressure regulating assembly, the adsorption force of the gripping thermal insulation substrate decreases, and the thermal insulation substrate falls smoothly onto the conveying assembly. Then, the adhesive spraying assembly applies adhesive to the thermal insulation substrate. During the application of adhesive, the electric push rod 6 of tray 4 is pushed back to its original position. Tray 4 also moves backward into recess 2 under the elastic force of spring 1, and tray 1 rotates. At the same time, the electric push rod 6 of the inner ring of another tray 1 pushes tray 4 to the position between the two trays 1, that is, the reinforcing fabric is pushed out. Then the gripping unit grips the reinforcing fabric and transfers it to the heat insulation cotton substrate sprayed with adhesive. Under the control of the pressure regulating component, the negative pressure environment for gripping the reinforcing fabric is broken at this time, and the reinforcing fabric falls smoothly onto the heat insulation cotton substrate. Then the conveying component conveys the heat insulation cotton substrate and reinforcing fabric that are attached together away. The above actions are repeated and the cycle continues.

[0055] The drive assembly can be composed of a motor-driven reducer, which can drive the gripping tube 8 to perform intermittent circular motion. When the right-angle tube 11 moves to the position between the two discs 1, under the downward constraint of the pressure rod 13, the suction cup 12 approaches the material on the tray 4, that is, the suction cup 12 adsorbs the heat insulation cotton substrate or the reinforcing fabric. When the right-angle tube 11 rotates again and passes the pressure rod 13, the right-angle tube 11 loses the downward pressure of the pressure rod 13, and the inclined tube 10 swings back to its original position under the elastic force of the spring 2 connected to it, and then transfers the heat insulation cotton substrate or the reinforcing fabric to the conveying assembly. The cooperative design of the inclined tube 10 and the right-angle tube 11 with the pressure rod 13 makes it easy for the suction cup 12 to adsorb the heat insulation cotton substrate or the reinforcing fabric on the tray 4, so as to avoid misalignment and inaccurate adsorption between the suction cup 12 and the material.

[0056] The conveyor belt 14 can rotate intermittently. That is, after the reinforcing fabric is attached to the heat insulation cotton substrate, the conveyor belt 14 will transport the material and then pause. After the heat insulation cotton substrate is transferred to the conveyor belt 14, as the extension rod rotates away from the conveyor belt 14, the cylinder 15 pushes the plate 16 to move above the heat insulation cotton substrate. Then, the external pump sprays glue onto the surface of the heat insulation cotton substrate. After the glue spraying is finished, the cylinder 15 drives the plate 16 to retract and reset. At this time, the suction cup 12 transfers the reinforcing fabric. Under the control of the pressure regulating component, the suction cup 12 loses the negative pressure environment, and the reinforcing fabric falls onto the surface of the heat insulation cotton substrate.

[0057] The negative pressure hood 18 is connected to the external negative pressure pump body. The inside of the negative pressure hood 18 is always in a negative pressure environment, and the rotation of the disc 1 will not interfere with the negative pressure hood 18. That is, the disc 1 can rotate normally. At the same time, the vent 17 can also be connected to the negative pressure hood 18. When the tray 4 is located in the recess 2, the vent 17 is connected to the adsorption hole 19. The negative pressure of the adsorption hole 19 can adsorb the material in the tray 4, that is, adsorb the heat insulation cotton substrate or the reinforcing fabric, so as to prevent the heat insulation cotton substrate or the reinforcing fabric from being thrown off the tray 4 when the disc 1 rotates.

[0058] The output end of the drive component, i.e., the output end of the reducer in this embodiment, is fixedly connected to an intermediate tube. A ring body rotates on the intermediate tube and is connected to it. The ring body can be connected to an external negative pressure pump body. The intermediate tube is connected to the gripping tube 8. The pressure regulating component controls the formation of the negative pressure environment of the suction cup 12. When the gripping tube 8 rotates to a position relative to the conveyor belt 14, the upper end of the pressure regulating rod 23 interferes with the pressure spring 26. That is, the pressure spring 26 presses down on the pressure regulating rod 23. The vent hole 25 in the lower half of the pressure regulating rod 23 extends to the base block 2. Below 0, the suction cup 12 connected to the gripping tube 8 loses its negative pressure environment, meaning the suction cup 12 can no longer adsorb the heat insulation cotton substrate or reinforcing fabric, ensuring that the heat insulation cotton substrate or reinforcing fabric falls smoothly; the gripping tube 8 continues to rotate, the pressure regulating rod 23 loses the pressure of the squeezing spring 26, and the pressure regulating rod 23 moves upward under the elastic force of the pressure spring connected to it. At this time, the vent hole 25 is blocked, the air passage 24 is connected to the gripping tube 8 normally again, and the suction cup 12 also restores the negative pressure environment for adsorbing materials.
