Description

Technical Field

[0001] This application relates to the field of coating technology for adhesives on grinding wheel substrates, and more particularly to an auxiliary coating device for adhesives on grinding wheel substrates. Background Technology

[0002] Grinding wheels are the most widely used and extensive type of abrasive. They rotate at high speeds to perform grinding, grooving, and cutting operations on the outer and inner diameters, planes, and various profiles of metal or non-metal workpieces. Grinding wheels are formed by bonding abrasive grains to a wheel matrix using a bonding agent; common abrasives include diamond.

[0003] Currently, in the manufacturing process of diamond grinding wheels, the first step is to apply an adhesive to the grinding wheel substrate. Since the working surface of the grinding wheel is typically a certain width extending inwards from its outer edge, the bonding width of the diamond abrasive is usually smaller than the radius of the substrate (as shown in the instruction manual). Figure 2 (Structure shown in the lower middle of the attached diagram). Currently, when applying adhesive, the substrate is typically fitted onto the rotating shaft. Figure 3 As shown), a certain amount of adhesive is manually piled onto the substrate at the designated adhesive application location. Then, the substrate is continuously and slowly rotated while the piled adhesive is smoothed circumferentially using fingers or a scraper (as shown). Figure 2 (As shown in the attached diagram on the upper middle side), then the diamond abrasive is bonded onto the adhesive. After the bonding is firm, the diamond grinding wheel product can be formed.

[0004] Currently, when applying adhesive, it is difficult to accurately determine the amount of adhesive used manually. This leads to problems such as too much or too little adhesive after circumferential smoothing, requiring additional application or removal of excess adhesive. Furthermore, inconsistencies in the smoothing width and thickness occur during manual smoothing (e.g., ...). Figure 4 (as shown in the diagram), and scraping the adhesive to the outside of the substrate ( Figure 4 (As indicated by the middle arrow) This leads to the problem of diamond abrasive falling off and being wasted. Furthermore, after bonding the diamond abrasive later, the uneven surface height of the abrasive affects the performance of the diamond grinding wheel. Unstable contact forces with the workpiece can also cause diamond abrasive splashing and wheel breakage, posing safety hazards. Summary of the Invention

[0005] To address the aforementioned problems, this application aims to provide an auxiliary coating device for adhesive on the surface of a grinding wheel substrate. This device can solve the problem of inconsistent width and thickness in the current manual coating of adhesive, improve the coating quality of the adhesive and the flatness of the diamond abrasive bonding, and also solve the problem of excessive or insufficient adhesive dosage in the current manual application, thereby improving the working efficiency of continuous coating of substrate adhesive.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: an auxiliary coating device for adhesive on the surface of a grinding wheel substrate, wherein the grinding wheel substrate is sleeved on a rotating shaft for rotary coating, characterized in that: the auxiliary coating device includes a support frame connected to the rotating shaft, and a coating mechanism is provided on the outside of the support frame that is parallel to and corresponds to the adhesive coating position on the surface of the grinding wheel substrate.

[0007] Preferably, the coating mechanism includes a glue storage tank connected to a support frame, with a glue-holding port at the upper end and a glue outlet at the lower end parallel to the surface of the grinding wheel substrate, and the width of the glue outlet is equal to the width of the glue coated on the grinding wheel substrate.

[0008] Preferably, the lower side of the glue outlet of the glue storage tank is configured as an inverted conical structure.

[0009] Preferably, a sealing plate that can block the glue outlet is hinged to the inner wall of the glue outlet.

[0010] Preferably, the support frame includes a cover sleeved on the rotating shaft and a support rod connecting the cover and the glue storage tank. One end of the support rod is vertically adjustable to the cover, and the other end is hinged to the glue storage tank.

[0011] The beneficial effects of this application are: the coating mechanism can store the adhesive, and with a structure parallel to the substrate surface, it can ensure the consistency of the thickness and width of the outflowing adhesive, thereby solving the problem of inconsistent width and thickness in the current manual coating of adhesive, improving the coating quality of the adhesive and the flatness of the diamond abrasive bonding, and also solving the problem of excessive or insufficient adhesive dosage in the current manual accumulation, which can effectively improve the working efficiency of continuous coating of substrate adhesive.

[0021] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] See attached document Figures 1-8 This invention discloses an auxiliary coating device for adhesive on the surface of a grinding wheel substrate. The grinding wheel substrate is currently mounted on a rotating shaft, and the adhesive is applied manually while the shaft is rotating. To address the problem of inconsistent width and thickness of the adhesive applied manually, which affects grinding quality and safety, this application presents an auxiliary coating device. The device includes a support frame 1 connected to the rotating shaft, and a coating mechanism parallel to the adhesive application position on the grinding wheel substrate surface is located on the outer side of the support frame 1. During operation, the grinding wheel substrate is first mounted on the rotating shaft, and then the support frame 1 is connected to the rotating shaft on the top side of the substrate. The coating mechanism can store the adhesive. During the rotation of the grinding wheel substrate, the adhesive flows out from the coating mechanism at a uniform speed. Since the coating mechanism is parallel to the substrate surface, the consistency of the thickness and width of the adhesive flowing out can be guaranteed. This solves the problem of inconsistent width and thickness in the current manual application of adhesive, improves the coating quality of the adhesive and the flatness of the diamond abrasive bonding, and also solves the problem of excessive or insufficient adhesive dosage in the current manual application. It can effectively improve the working efficiency of continuous coating of substrate adhesive.

[0023] Specifically, such as Figure 5-6 As shown, the coating mechanism includes a glue storage tank 2 connected to a support frame 1. The glue storage tank 2 has a glue inlet 2a at its upper end and a glue outlet 2b at its lower end, parallel to the surface of the grinding wheel substrate. The width of the glue outlet 2b is equal to the width of the glue coated on the grinding wheel substrate. During coating, adhesive is stored in the glue storage tank 2 through the glue inlet 2a. As the substrate rotates, the adhesive continuously flows out onto the substrate surface through the lower glue outlet 2b. The thickness of the coating can be controlled and adjusted according to the distance between the glue outlet 2b and the substrate surface, while the width of the glue outlet 2b ensures consistent coating width. During the coating process, the amount of adhesive in the glue storage tank 2 can be monitored and added in real time through the glue inlet 2a, thus solving the problem of excessive or insufficient adhesive due to manual metering.

[0024] To further precisely control the amount of adhesive flowing out, preferably, such as Figure 6 As shown, the lower side of the adhesive outlet 2b in the adhesive storage tank 2 is designed with an inverted conical shape. This structure effectively reduces the outflow of adhesive, preventing excessive outflow from affecting the adhesive coating thickness and causing waste.

[0025] During the process of removing the substrate after applying the adhesive, to prevent excess adhesive from flowing out of the adhesive outlet 2b onto the substrate surface and causing waste, such as... Figure 7-8 As shown, a sealing plate 21 is hinged to the inner wall of the glue outlet 2b to block the glue outlet 2b. A drive rod (not shown) connected to the hinge rod of the sealing plate 21 is provided on the outer wall of the glue storage tank 2. After glue application, the rotation of the outer drive rod drives the sealing plate 21 to rotate, causing the bottom end of the sealing plate 21 to contact the inner wall of the opposing glue storage tank 2, thereby blocking the glue outlet 2b. Figure 8 (As shown), thus allowing the coating device and substrate to be easily disassembled from the rotating shaft.

[0026] To improve the applicability of this coating device, such as Figure 5 As shown, the support frame 1 includes a cover 11 sleeved on a rotating shaft and a support rod 12 connecting the cover 11 and the glue storage tank 2. One end of the support rod 12 is vertically adjustable to the cover 11, and the other end is hinged to the glue storage tank 2. Preferably, a screw (not shown in the figure) is provided at the top of the cover 11, and one end of the support rod 12 is sleeved on the screw. The height of the support rod 12 and the glue storage tank 2 can be adjusted by a double nut structure. The support rod can also be configured as a telescopic rod structure. The support rod 12 and the glue storage tank 2 are preferably hinged by the screw. After the angle of the glue storage tank 2 is adjusted (to achieve parallelism with the substrate surface), the screw can lock the adjusted state of the glue storage tank 2. Thus, the coating device can be used for glue coating operations on substrates of different specifications, improving the applicability of the coating device.

[0027] The principle of this application is as follows: During adhesive application, the substrate is first fitted onto the rotating shaft, and then the entire coating device is connected to the rotating shaft via the cover. Next, by adjusting the height and length of the support rod and the deflection angle of the adhesive reservoir 2, the outlet 2b of the reservoir is aligned with and parallel to the adhesive application position on the substrate surface. Adhesive is then stored in the reservoir 2. The substrate is then rotated at a relatively uniform speed, allowing the adhesive in the reservoir 2 to flow through the outlet 2b to the substrate surface for coating. After circumferential coating is completed, the drive rod on the outside of the reservoir 2 is driven, causing the bottom end of the sealing plate 21 to contact the inner wall of the opposite reservoir 2, thus sealing the outlet 2b. This allows for easy disassembly of the coating device and substrate from the rotating shaft, completing a rapid adhesive application operation on a substrate.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this application. Various changes and modifications may be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
