Description

Technical Field

[0001] This utility model mainly relates to the field of glue application technology, specifically a glue application device for epoxy resin or adhesive. Background Technology

[0002] When applying epoxy resin or similar adhesives, appropriate dispensing devices are required. Currently, dispensing devices are mostly divided into electric and manual dispensing machines. Manual dispensing machines primarily use a push-type method, where epoxy resin or adhesive is poured into a container and then dispensing is achieved by pushing a piston. This method results in a small amount of adhesive dispensed at a time, low dispensing efficiency, and high labor intensity. Electric dispensing machines can achieve automatic dispensing, but they are more expensive and have lower adoption rates. Regardless of whether it's a traditional manual or electric dispensing machine, adhesive will contaminate the container, piston, or pump body during dispensing, requiring prompt and cumbersome cleaning after use. Utility Model Content

[0003] To address the shortcomings of current technology, this utility model, based on existing technology and practical application, provides a glue applicator for epoxy resin or adhesive. This device uses a roller to squeeze a flexible tube to apply the glue. The epoxy resin or adhesive only flows inside the tube and will not contaminate the external structure of the tube. Therefore, after use, only the tube needs to be cleaned or replaced. Moreover, the glue applicator is simple and convenient to operate and allows for adjustment of the glue flow rate and pressure.

[0004] The technical solution of this utility model is as follows:

[0005] An adhesive applicator for epoxy resin or glue includes a base plate on which a flow channel support is mounted. A turntable is provided on one side of the flow channel support and connected to a rotating shaft. An arc-shaped flow channel is provided inside the flow channel, and a glue tube is provided inside the flow channel. One end of the glue tube is connected to a storage tank, and the other end is an outlet. A pressure roller is provided on the side of the turntable, and the pressure roller can squeeze the glue tube when the turntable rotates.

[0006] Furthermore, a fixing buckle is provided at each end of the flow channel support, and the fixing buckle is used to fix the rubber tube.

[0007] Furthermore, the flow channel support includes a first inclined surface, an arc surface, and a second inclined surface. The arc surface is located between the first inclined surface and the second inclined surface. The flow channel is located on the arc surface. Two fixing buckles are respectively located at the outer ends of the first inclined surface and the second inclined surface.

[0008] Furthermore, the rolling roller is mounted on the side of the turntable via a connecting shaft, and a bearing is provided between the rolling roller and the connecting shaft.

[0009] Furthermore, three rolling rollers are provided on the side of the turntable, and the three rolling rollers are evenly arranged around the circumference of the turntable.

[0010] Furthermore, the flow channel is a groove set on the upper surface of the flow channel support, and the curvature of the flow channel is designed so that any two rolling rollers can be connected during operation, ensuring the continuity of the extrusion hose.

[0011] Furthermore, the surface of the rolling roller is made of rubber.

[0012] Furthermore, the base plate is provided with two pivot supports, the pivot is supported by the pivot supports, a bearing is provided between the pivot and the pivot supports, and a handle is provided at one end of the pivot.

[0013] Furthermore, the bottom of the flow channel support is connected to the base plate by screws.

[0014] Furthermore, the base plate is provided with reserved holes for fixing the glue applicator or installing the wheels.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model adopts the principle of negative pressure suction. The external roller squeezes the hose, causing the hose to compress and deform to generate negative pressure, which draws glue from the storage tank to complete the work. During the whole process, the glue only flows inside the hose and does not come into contact with other parts, so it will not contaminate other parts. After use, only the hose needs to be cleaned or the hose can be replaced directly. Compared with the traditional structure, it is more convenient to use and maintain. During the glue supply process, only the rotating shaft needs to be turned to continuously draw glue from the storage tank, resulting in high glue application efficiency and low labor intensity.

[0017] 2. This utility model can change the glue supply pressure by adjusting the gap between the base plate and the flow channel, and can change the glue supply flow rate by controlling the rotation speed of the turntable. Any two rolling rollers can be connected during operation to ensure the continuity of work.

[0018] 3. The surface of the roller of this utility model is made of rubber, which reduces noise during operation and prevents damage to the glue tube. The base plate has reserved holes to install traveling wheels to facilitate the movement of the glue dispensing device. The base plate and the flow channel support are connected by screws, and the gap between them can be adjusted by adding or removing shims, thereby changing the glue supply pressure.

[0026] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0027] This embodiment provides a glue applicator, which is mainly used for applying glue to viscous substances such as epoxy resin and adhesive.

[0028] refer to Figures 1-5 As shown in the figure, in this embodiment, the device mainly includes a base plate 4, a flow channel support 3, a rubber hose 2, a storage tank 1, a turntable 6, etc.

[0029] The base plate 4, as a component providing support for other parts, needs to be high-strength, sturdy, and reliable. Furthermore, since the application of adhesives often changes, it must also be lightweight and easy to move. Therefore, the base plate is made of a single piece of aluminum alloy sheet, which is lightweight and high-strength. Pre-drilled holes 41 are machined into the base plate 4, through which wheels can be installed, allowing the device to be quickly moved and fixed.

[0030] The flow channel support 3 is mainly used to place the hose 2 and plan the shape of the hose 2. It needs to have high precision and strength. Therefore, the flow channel support 3 is made of tempered steel to ensure sufficient hardness and wear resistance, as well as good machinability to ensure machining accuracy.

[0031] For the specific structure of the flow channel support 3, please refer to the following: Figure 4As shown. It is fixedly mounted on one side of the base plate 4 by two screws. The flow channel support 3 includes a first inclined surface 31, an arc surface 32, and a second inclined surface 33. The arc surface 32 is located between the first inclined surface 31 and the second inclined surface 33. A groove is provided on the upper surface of the arc surface 32, which forms a flow channel 34 for placing and planning the shape of the hose 2. The arrangement of the hose 2 on the flow channel support 3 is as follows. Figure 1 As shown.

[0032] The turntable 6 is set on one side of the flow channel support 3. One end of the turntable 6 is connected to a rotating shaft 8. The rotating shaft 8 is supported by two rotating shaft seats 10 with bearings. The rotating shaft seats 10 are fixed on the base plate 4. One end of the rotating shaft 8 has a handle 9, which can drive the turntable 6 to rotate.

[0033] Three rollers 7 are arranged on the turntable 6 near the flow channel support 3, spaced 120° apart. The rollers 7 are mounted on the side of the turntable 6 via a bearing-bearing connecting shaft 11. As the turntable 6 rotates, the rollers 7 move to the flow channel 34 of the flow channel support 3, squeezing the rubber tube 2 within the flow channel 34 to create negative pressure, thereby drawing glue from the storage tank 1 and allowing it to flow out through the outlet of the rubber tube 2. In this embodiment, the arc shape of the flow channel 34 is adapted to the arc shape of the rollers 7's movement path; that is, the rollers 7 continuously compress the rubber tube 2 from the initial position of the flow channel 34 until they reach the end of the flow channel 34, ensuring a continuous flow of glue. The outer skin of the rollers 7 is made of rubber to reduce noise and prevent damage to the rubber tube 2 during operation.

[0034] In this embodiment, the arc of the flow channel 34 is designed to be 115°. When the first rolling roller 7 runs to the end of the flow channel 34, the next rolling roller 7 runs to the beginning of the flow channel 34. In this way, any two rolling rollers can be connected during operation, ensuring the continuity of the operation.

[0035] In this embodiment, a fixing buckle 5 is provided at each end of the flow channel support 3 to fix the glue tube 2. At the same time, the flow channel support 3 is connected to the base plate 4 by screws. By loosening the screws and adding shims between the base plate 4 and the flow channel support 3, the distance between the flow channel support 3 and the base plate 4 can be adjusted. In this way, the depth of compression of the glue tube 2 by the roller 7 can be changed, thereby adjusting the glue dispensing pressure. The glue dispensing flow rate can be adjusted by controlling the rotation speed of the handle 9.

[0036] This glue dispensing device operates on a negative pressure suction principle. The rotating disc 6 drives the roller 7 to compress the glue tube 2, causing it to deform and generate negative pressure, which draws glue from the storage tank 1, completing the process. Its operation is as follows: The employee first presses... Figure 1As shown, fix the hose 2 to the flow channel support 3, turn the handle 9 to drive the turntable 6 to rotate counterclockwise, so that the three rollers 7 will compress the hose 2 in sequence. During the compression of the hose 2, a negative pressure will be generated, which will draw out the glue in the storage tank 1 and make the glue flow out evenly along the hose 2 and be injected into the equipment.
