Description

Technical Field

[0001] The present invention relates to a liquid resin gluing machine structure, and more particularly to an automatic glue supply system for composite resin blocks that instantly and locally melts resin blocks to accurately provide sufficient liquid resin volume. Background Art

[0002] A known gluing machine, such as the "gluing machine structure" approved by China on September 24, 2003, is a base fixedly provided above the two gluing wheels, the top surface of the base is provided with a heating plate, and the top surface of the base is provided with a preparation barrel for leaning against so that the bottom surface of the preparation barrel can contact the two heating plates, and the preparation barrel has a hollow flow channel so that the glue in the preparation barrel can flow from the flow channel between the two gluing wheels. The rubber material in the barrel is continuously preheated by the heating plate, so that the rubber material in the preparation barrel is kept at 150℃~200℃, so that the rubber material in the preparation barrel can flow from the flow channel to the two upper rubber wheels for gluing operation. However, it is not difficult to find that there are still some shortcomings in the above-mentioned known structure. The main reasons are as follows: (1) The heating plate continuously heats the preparation barrel, so that a large amount of resin is melted in the preparation barrel at the same time, so a large amount of energy is required to maintain its heating temperature, thereby increasing the production cost of the gluing operation; (2) The preparation barrel is heated by the heating plate, so that a large amount of resin is melted in the preparation barrel at the same time, thereby increasing the production cost of the gluing operation; (3) The preparation barrel is heated by the heating plate, so that the resin is heated by the heating plate, so that the resin is heated by the heating plate, thereby increasing the production cost of the gluing operation; (4) The preparation barrel is heated by the heating plate, so that the resin is heated by the heating plate, so that the resin is heated by the heating plate. When the stock of the barrel becomes low, new resin blocks will be added to achieve the purpose of continuous gluing. However, based on the material properties of the resin blocks, after the resin blocks are melted into liquid form, they will gradually deteriorate and solidify over time. When new and old liquid resins are mixed in the preparation barrel, the resin coated on the substrate (release paper) will have different heating times. Resins with different heating times will form different structural strengths when baked. When the structural strength is uneven, the finished product will be prone to local cracking; (3) The flow rate of the preparation barrel is manually controlled by the diameter of the flow channel below, and it does not have the function of automatically adjusting the supply amount. The heating plate cannot automatically control the heating temperature. When the liquid resin in the preparation barrel becomes less, the heating temperature of the heating plate will be too high, which will increase the fluidity of the liquid resin and the amount of glue applied will increase excessively. Conversely, when the liquid resin in the preparation barrel becomes more, the fluidity of the liquid resin decreases due to insufficient heating. Therefore, the preparation barrel cannot provide stable liquid resin for gluing operations.

[0003] In view of this, the inventor, with many years of experience in manufacturing, developing and designing related products, has, after detailed design and careful evaluation aimed at the above-mentioned goals, finally arrived at a truly practical present invention. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an automatic glue supply system for composite resin blocks in response to the above-mentioned deficiencies in the prior art.

[0005] A conveying device includes two side plates, multiple rollers, a motor and a conveyor belt. The above rollers are all connected between the two side plates and are arranged parallel to each other. The conveyor belt is annular and surrounds all the rollers, and the motor is connected to any of the rollers. A heating plate is installed on the two side plates, and the heating plate is located between two adjacent rollers, and the heating plate is adjacent to the inner side of the conveyor belt. A molten resin rack is arranged between the two side plates above the conveying device. The molten resin rack is surrounded by at least one feeding port in the shape of a window frame, and the heating plate is spaced below the feeding port by the conveyor belt. The feeding port provides a place for a single resin block. A scraper is arranged below the conveying device, and the scraper contacts the outer side of the conveyor belt.

[0006] It further includes a gluing device, the conveying device is fixed above the gluing device, and the gluing device is provided with two gluing steel wheels parallel to each other. A resin tank is formed between the two gluing steel wheels, and the scraper is located above the resin tank.

[0007] The glue coating device is equipped with a baffle at both ends of the glue coating steel wheel, and the baffle simultaneously abuts against the two glue coating steel wheels to surround the resin tank.

[0008] Both ends of the scraper have sliding resistance and are arranged on a slide rail, and the slide rail is fixed to the glue coating device.

[0009] The rollers include a first roller, a second roller, a third roller and a fourth roller arranged in a square shape. The heating plate is located between the first roller and the second roller, and the scraper contacts the outer side of the conveyor belt located at the third roller.

[0010] A heat preservation plate is provided between the first roller and the third roller, and the heat preservation plate is adjacent to the inner side surface of the conveyor belt.

[0011] A preheating plate is provided between the second roller and the fourth roller, and the preheating plate is adjacent to the inner side surface of the conveyor belt.

[0012] Two side plates are symmetrically provided with a movable groove, and both ends of the fourth roller are passed through the movable groove. A tension controller is installed at one end of the fourth roller, and the tension controller drives the second roller to move along the movable groove.

[0013] It further includes a control computer, which is electrically connected to the motor, the heating plate, the insulation plate and the preheating plate, and the control computer is provided with a plurality of control buttons and a display interface. The control computer is also connected to a liquid level sensor, and the liquid level sensor is arranged above the two rubber-coated steel wheels.

[0014] Two shaft seats are fixed symmetrically on the two side plates, and the molten resin frame is provided with a shaft portion on both sides. The molten resin frame is pivotally mounted on the shaft seat via the shaft portion.

[0015] The first main purpose of the present invention is to place the resin block at the loading port of the molten resin rack, and then use the heating plate to locally heat the side of the resin block that is against the conveyor belt, so that the lower part of the resin block is locally melted to form liquid resin. The liquid resin adheres to the conveyor belt and is scraped off by the scraper for use in the gluing operation. That is, only liquid resins with the same heating time can be provided, which not only avoids the situation where the resin raw material has insufficient reaction life (qualitative change and solidification) due to continuous heating time for too long, but also will not be affected by liquid resins with different continuous heating times, which will lead to uneven structural strength after baking, so that uniform structural strength can be obtained during baking and curing.

[0016] The second main purpose of the present invention is that when the liquid level sensor detects that the liquid resin level in the resin tank is too low, the control computer will increase the temperature of the heating plate, thereby increasing the flow rate of the melted resin block to form liquid resin. If the supply of liquid resin is to be further increased, the circulating speed of the conveyor belt can also be simultaneously accelerated. That is, the control computer cooperates with the liquid level sensor to automatically adjust the flow rate of the liquid resin, thereby achieving the effect of automatically adjusting the flow rate of the liquid resin.

[0017] A third primary objective of the present invention is that, when the circulating speed of the conveyor belt slows down, the time the liquid resin stays on the conveyor belt increases, and the control computer can automatically increase the heating temperature of the insulation plate, thereby maintaining the liquid fluidity of the liquid resin. Furthermore, when the circulating speed of the conveyor belt suddenly accelerates, the heating plate and the preheating plate can simultaneously increase the heating temperature, so that the melting speed of the resin block can react immediately, thereby achieving the effect of real-time adjustment and precise control of the flow rate.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] The structural principle and working principle of the present invention are described in detail below with reference to the accompanying drawings:

[0057] Please first Figure 1 、 Figure 2 and Figure 3 As shown, an automatic glue supply system for composite resin blocks includes: a conveying device 10, a heating plate 20, a molten resin rack 30, a scraper 40 and a glue coating device 50, a conveying device 10 includes two side plates 11, a plurality of rollers 12, a motor 13 and a conveyor belt 14, the rollers 12 are connected between the two side plates 11, and the rollers 12 are arranged parallel to each other, the conveyor belt 14 is annular and surrounds all the rollers 12, and the motor 13 is connected to any of the rollers 12, thereby driving the rollers 12 to drive the conveyor belt 14 to rotate, a heating plate 20 is installed The heating plate 20 is located between the two adjacent rollers 12, and the heating plate 20 is adjacent to the inner side of the conveyor belt 14. A molten resin rack 30 is provided between the two side plates 11 above the conveyor 10, wherein the two side plates 11 are symmetrically fixed with two shaft seats 111, and the molten resin rack 30 is provided with a shaft portion 31 on both sides. The molten resin rack 30 is pivotally mounted on the shaft seat 111 with the shaft portion 31, so that the molten resin rack 30 can be lifted up with the shaft seat 111 as the axis, thereby facilitating the cleaning operation of the molten resin rack 30 (cooperating with the molten resin rack 30). Figure 6 As shown), the molten resin rack 30 is provided with at least one feeding port 32 in a window frame shape, and the heating plate 20 is spaced apart from the conveyor belt 14 below the feeding port 32, and the feeding port 32 provides a single resin block A for placement, a scraper 40 is provided below the conveyor device 10, the scraper 40 is in contact with the outer side of the conveyor belt 14, so that the liquefied resin hot-melt adhered to the conveyor belt 14 can be scraped off by the scraper 40, a glue coating device 50 is fixed above the conveyor device 10, and the glue coating device 50 is provided with two glue coating steel wheels 51 parallel to each other, and a resin tank 5 is formed between the two glue coating steel wheels 51. 2, and the scraper 40 is located above the resin tank 52, and the glue coating device 50 is equipped with a baffle 53 at both ends of the glue coating steel wheel 51, and the baffle 53 simultaneously resists the two glue coating steel wheels 51 and surrounds the resin tank 52, and both ends of the scraper 40 are provided with sliding resistance on a slide rail 41, and the slide rail 41 is fixed to the glue coating device 50, thereby allowing the scraper 40 to slide and adjust its position and facilitate cleaning. In summary, the material placement port 32 of the molten resin rack 30 provides a place for the resin block A, and the heating of the heating plate 20 causes the resin block A to be partially melted to form a liquid resin B (with Figure 4 As shown), the liquid resin B adheres to the conveyor belt 14 and is scraped off by the scraper 40, thereby replenishing the required amount of glue in real time during the gluing operation and providing only the liquid resin B with the same heating time, so as to obtain uniform structural strength during baking and curing.

[0058] Further explain its specific implementation, cooperate Figure 1 、 Figure 2 、 Figure 3 As shown, the conveying device 10 is assembled with the roller 12 by two side plates 11. The roller 12 includes a first roller 121, a second roller 122, a third roller 123 and a fourth roller 124 arranged in a square shape. The heating plate 20 is located between the first roller 121 and the second roller 122. A heat preservation plate 21 is provided between the first roller 121 and the third roller 123, and a preheating plate 22 is provided between the second roller 122 and the fourth roller 124. The motor 13 is connected to one side of the first roller 121, and the first roller 121 is driven by the motor 13 to rotate, and then the conveyor belt 14 is sleeved. On the periphery of the above-mentioned roller 12, the insulation plate 21 and the preheating plate 22 are both adjacent to the inner side of the conveyor belt 14. In addition, the molten resin rack 30 is pivoted on the shaft seat 111 of the two side plates 11 with the shaft portion 31, so that the material loading port 32 of the molten resin rack 30 is located directly above the heating plate 20. The conveying device 10 is fixed above the glue coating device 50, and the two ends of the scraper 40 are set on the slide rail 41 at the glue coating device 50. The scraper 40 contacts the outer side of the conveyor belt 14 at the third roller 123, and the scraper 40 is simultaneously located above the resin tank 52 of the two glue coating steel wheels 51, thereby completing the structural combination.

[0059] To further explain its operation and function, please Figure 1 Continuous to Figure 5As shown, the resin block A is placed at the feeding port 32 of the resin molten rack 30, so that the resin block A is placed flat on the conveyor belt 14. The heating plate 20 then locally heats the side of the resin block A that contacts the conveyor belt 14, causing the lower part of the resin block A to melt to form liquid resin B. The liquid resin B will adhere to the conveyor belt 14. The conveyor belt 14 can be made of a Teflon woven cloth coated with silicone to form a closed loop belt with a fixed length, so that the liquid resin B can be accommodated. The liquid resin B is easily adhered to the conveyor belt 14 and is also easily scraped off and cleaned. The motor 13 can drive the first roller 121 to rotate, and link the second roller 122, the third roller 123, the fourth roller 124 and the conveyor belt 14 to form a synchronous rotation, that is, the conveyor belt 14 adhered with the liquid resin B is moved toward the third roller 123. Since the scraper 40 contacts the surface of the conveyor belt 14 at the third roller 123, the liquid resin B is scraped off. The resin block A is then locally melted by the heating plate 20, thereby providing only liquid resin B with the same heating time. This prevents the resin raw material from having a short reaction life (hardening and deterioration) due to prolonged heating, and also prevents uneven structural strength after baking due to the influence of liquid resin B with different heating times. In terms of energy consumption, the present invention's technical approach of locally melting the resin block A consumes less heat energy than the conventional method of simultaneously melting a barrel of liquid resin, thereby reducing production costs.

[0060] The heating plate 20 heats the resin block A to form a partially melted liquid resin B. The liquid resin B adheres to the conveyor belt 14 and moves from the first roller 121 end to the third roller 123. The scraper 40 scrapes the liquid resin B and drops it into the resin tank 52 for gluing. The conveying device 10 is provided with the insulation plate 21 between the first roller 121 and the third roller 123, and the preheating plate 22 is provided between the second roller 122 and the fourth roller 124. The insulation plate 21 and the preheating plate 22 are both adjacent to the inner side of the conveyor belt 14. The insulation plate 21 is used to heat the first roller 121 and the third roller 123. The liquid resin B between the roller 121 and the third roller 123 is heated, so that the liquid resin B can be stably maintained in a liquid state, thereby preventing the liquid resin B from cooling down too quickly. After the liquid resin B is scraped off by the scraper 40, the conveyor belt 14 returns along the third roller 123, the fourth roller 124 and the second roller 122 to between the heating plate 20 and the resin block A. At this time, the conveyor belt 14 is preheated by the preheating plate 22 located between the second roller 122 and the fourth roller 124, thereby improving the heating efficiency of the heating plate 20 and allowing the flow rate of the liquid resin B to be greatly adjusted according to usage requirements.

[0061] Among them, the two side plates 11 are symmetrically provided with a movable groove 112, and the two ends of the fourth roller 124 are inserted into the movable groove 112. A tension controller 15 is installed at one end of the fourth roller 124, and the tension controller 15 drives the second roller 122 to move along the movable groove 112, thereby supporting the conveyor belt 14 to form a stable tension.

[0062] Please ask Figure 1 Continuous to Figure 5As shown, the present invention further includes a control computer 60, which is electrically connected to the motor 13, the heating plate 20, the heat preservation plate 21 and the preheating plate 22, and the control computer 60 is provided with a plurality of control buttons 61 and a display interface 62, through which the control buttons 61 and the display interface 62 are set and operated to control the speed of the motor 13, the heating plate 20, the heat preservation plate 21 and the preheating plate 22, wherein the heating plate 20, the heat preservation plate 21 and the preheating plate 22 are all The internal flow channel circulates with heat transfer oil, which forms a stable heating temperature. The control computer 60 is connected to a liquid level sensor 63, and the liquid level sensor 63 is set above the two glue-coating steel wheels 51. The liquid level sensor 63 detects the liquid level of the liquid resin B in the resin tank 52 and transmits the liquid level signal to the control computer 60 for judgment. When the liquid level sensor 63 detects that the liquid level of the liquid resin B in the resin tank 52 is too low, the control computer 60 will increase the temperature of the heating plate 20 to increase the temperature of the heating plate 20. The flow rate of the liquid resin B formed by the melting of the resin block A is increased. If the supply of the liquid resin B is to be further increased, the circulating speed of the conveyor belt 14 can also be accelerated simultaneously. On the contrary, when the liquid level sensor 63 detects that the liquid resin B in the resin tank 52 is too high, the control computer 60 will lower the temperature of the heating plate 20 to reduce the flow rate of the liquid resin B formed by the melting of the resin block A, thereby achieving the effect of automatically adjusting the flow rate of the liquid resin B. Further, when the circulating speed of the conveyor belt 14 is slowed down, the liquid resin B is As the residence time of the liquid resin B on the conveyor belt 14 increases, the control computer 60 can automatically increase the heating temperature of the insulation plate 21, thereby maintaining the fluidity of the liquid resin B. When the circulating speed of the conveyor belt 14 suddenly increases, the heating plate 20 and the preheating plate 22 can simultaneously increase the heating temperature, so that the melting speed of the resin block A can be immediately reflected. In summary, the control computer 60 cooperates with the liquid level sensor 63 to automatically adjust the flow rate of the liquid resin B, thereby achieving the effect of real-time adjustment and precise control of the flow rate.

[0063] In summary, this invention has indeed achieved a breakthrough structural design and possesses improved inventive content, while also being able to achieve industrial applicability and advancement.
