Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment technology, and in particular to an automatic adhesive coating machine for friction wheels. Background Technology

[0002] Friction wheels are core components of industrial transmission and conveying equipment, and their edges must be coated with adhesive to meet usage requirements. On the one hand, the adhesive coating allows the friction wheel to bond firmly to components such as linings and frames, preventing slippage during transmission and ensuring stable power transmission. On the other hand, the adhesive layer reduces wear and noise on the friction wheel edges and improves oil and corrosion resistance, making it suitable for complex industrial environments. Especially in critical scenarios such as braking and conveying drives, the quality of the adhesive coating directly affects the safe operation of the equipment.

[0003] Currently, applying adhesive to the edge of friction wheels is mainly done manually, sometimes using simple hand spray guns or adhesive dipping tools. During operation, workers hold the tool and apply the adhesive to the edge of the friction wheel, sometimes using simple clamps to hold the workpiece in place. After application, the wheel is manually moved to the next process. This manual adhesive application method is not only inefficient, but the adhesive is also extremely prone to splashing onto workers, posing a health hazard. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide an automatic glue applicator for friction wheels to solve the problem of low efficiency of existing manual glue application methods as pointed out in the background art.

[0005] This utility model solves the above-mentioned technical problems through the following technical means: An automatic glue applicator for friction wheels, comprising: glue container; A glue brush, wherein one end of the glue brush has bristles, and the glue brush has a glue injection channel inside, one end of the glue injection channel being connected to the bristles; A liquid supply pump, wherein the inlet end of the liquid supply pump is connected to the glue container, and the outlet end is connected to the glue injection channel; A rotating mechanism, wherein the rotating mechanism is used to place the friction wheel and drive the friction wheel to rotate; and A telescopic mechanism is provided for driving the glue brush to move and enabling the bristles of the glue brush to contact the edge of the friction wheel.

[0006] In one possible implementation, the rotating mechanism includes a first support, a rotating disk, and a rotating drive, wherein the rotating drive is mounted in the first support, and the rotating disk is mounted on the output shaft of the rotating drive for holding a friction wheel.

[0007] In one possible implementation, the rotating disk has a first positioning element adapted to the center hole of the friction wheel, the first positioning element being able to be inserted into the center hole of the friction wheel.

[0008] In one possible implementation, the rotating mechanism further includes an upper cover capable of covering the non-adhesive area on the upper side of the friction wheel, and the rotating disk capable of covering the non-adhesive area on the lower side of the friction wheel.

[0009] In one possible implementation, the top cover has a second positioning element adapted to the center hole of the friction wheel, the second positioning element being able to be inserted into the center hole of the friction wheel.

[0010] In one possible implementation, the telescopic mechanism includes a second bracket, a clamp, and a telescopic drive member. The telescopic drive member is mounted on the second bracket, and the clamp is mounted on the output shaft of the telescopic drive member for clamping the glue brush.

[0011] In one possible implementation, the clamp includes a U-shaped frame, a clamping plate, and an elastic element. The U-shaped frame is mounted on the output shaft of the telescopic drive member, the clamping plate is movably mounted within the U-shaped frame, and the elastic element is mounted between the clamping plate and one side of the U-shaped frame. The glue brush can be clamped between the clamping plate and the side of the U-shaped frame away from the elastic element.

[0012] In one possible implementation, a plurality of guide rods are mounted on the clamp plate, the guide rods passing through one side of the U-shaped frame and fixed with a pull handle.

[0013] In one possible implementation, a waste collection box with a top opening is detachably mounted on the U-shaped frame, the open side of the waste collection box being located directly below the bristles.

[0014] In one possible implementation, a pressure regulating valve is also included, which is connected between the liquid supply pump and the glue injection channel.

[0015] The beneficial effects of this utility model are: The technical solution of this application automates the application of adhesive to a friction wheel. First, the friction wheel is placed on a rotating mechanism, which drives it to rotate. Then, a liquid pump delivers adhesive from the adhesive container to the brush bristles. Next, a telescopic mechanism moves the adhesive brush, causing its bristles to contact the edge of the rotating friction wheel, thus applying adhesive to its edge. After application, the telescopic mechanism resets the adhesive brush, detaching the bristles from the friction wheel, allowing the wheel to be removed. This design automates the adhesive application process, improving processing efficiency and reducing health hazards to workers. Attached Figure Description

Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0020] like Figures 1-3 As shown in the illustration, this application provides an automatic glue applicator for friction wheels, including a glue container 100, a glue brush 200, a liquid supply pump 300, a pressure regulating valve 400, a rotating mechanism, and a telescopic mechanism. The glue container 100 is primarily used to hold the mixed glue. One end of the glue brush 200 has bristles 210, and a glue injection channel is designed inside the glue brush 200. One end of the glue injection channel is connected to the bristles 210, allowing the glue in the injection channel to flow to the bristles 210, thus adhering the glue to the bristles 210.

[0021] The liquid supply pump 300 is detachably installed at the opening of the glue container 100. The inlet of the liquid supply pump 300 is connected to the glue container 100 via a first hose, the free end of which extends to the bottom of the glue container 100. The inlet of the liquid supply pump 300 is connected to the glue injection channel via a second hose. Driven by the liquid supply pump 300, the glue in the glue container 100 is output to the glue injection channel of the glue brush 200, ultimately flowing to the bristles 210. Furthermore, to limit the injection pressure in the glue injection channel and reduce excessive glue flow onto the bristles 210, a pressure regulating valve 400 is installed on the second hose between the liquid supply pump 300 and the glue injection channel. The worker can adjust the injection pressure according to the actual situation, aiming for a state where glue does not drip from the bristles 210.

[0022] The rotating mechanism is used to place the friction wheel 700 and drive the friction wheel 700 to rotate, while the telescopic mechanism is used to drive the glue brush 200 to move and enables the bristles 210 of the glue brush 200 to contact the edge of the friction wheel 700.

[0023] With the above technical solution, when applying adhesive to the friction wheel 700, the friction wheel 700 is first placed on a rotating mechanism, and the rotating mechanism drives the friction wheel 700 to rotate. Then, the adhesive in the adhesive container 100 is output to the brush bristles 210 by the liquid supply pump 300. Next, the adhesive brush 200 is moved by the telescopic mechanism, so that the bristles 210 of the adhesive brush 200 contact the edge of the rotating friction wheel 700, thereby applying adhesive to the edge of the friction wheel 700. After the adhesive application is completed, the adhesive brush 200 is driven to reset by the telescopic mechanism, so that the bristles 210 disengage from the friction wheel 700, and finally the friction wheel 700 is removed. This design, through automated adhesive application to the friction wheel 700, not only improves processing efficiency but also reduces hazards to worker health.

[0024] In this embodiment, the rotating mechanism includes a first support 510, a rotating disk 520, and a rotating drive 530. The rotating drive 530 is mounted within the first support 510 and can be a servo motor or a stepper motor. The rotating disk 520 is fixed to the output shaft of the rotating drive 530 and is used to hold the friction wheel 700. The rotating drive 530 drives the rotating disk 520 to rotate, thereby driving the friction wheel 700 to rotate. For ease of handling of the top cover 540, a handle 541 is mounted on the upper side of the top cover 540, allowing workers to easily pick up and place the top cover 540.

[0025] It is understandable that when the bristles 210 of the glue brush 200 contact the edge of the rotating friction wheel 700, the glue application area on the friction wheel 700 is uneven, and excessive areas are coated. Therefore, to ensure that the glue application area on the friction wheel 700 is uniform and correct, in this embodiment, the rotating mechanism also includes an upper cover 540, both of which are circular structures. The upper cover 540 covers the non-glue-coated area on the upper side of the friction wheel 700, and the rotating disk 520 covers the non-glue-coated area on the lower side of the friction wheel 700. Through the cooperation of the upper cover 540 and the rotating disk 520, the non-glue-coated area of ​​the friction wheel 700 can be temporarily covered. This ensures that excessive and uneven glue is applied only to the upper cover 540 and the rotating disk 520, and not to the friction wheel 700, thereby ensuring a uniform and correct glue application area on the friction wheel 700 and improving the glue application quality.

[0026] Furthermore, to ensure that the friction wheel 700 and the rotating disk 520 can rotate concentrically, the rotating disk 520 has a first positioning member 521 in its center that matches the center hole of the friction wheel 700. The first positioning member 521 can be inserted into the center hole of the friction wheel 700. This ensures that the friction wheel 700 and the rotating disk 520 rotate concentrically, improving the uniformity of adhesive application, and also positions the friction wheel 700. It should be noted that the friction wheel 700 itself has a circular center hole in its center. In addition, the first positioning member 521 and the center hole of the friction wheel 700 can have a slight interference fit, thereby ensuring that the friction wheel 700 can rotate with the rotating disk 520 during the adhesive application process.

[0027] Similarly, in order to enable the upper cover 540 and the friction wheel 700 to rotate concentrically, the lower middle part of the upper cover 540 has a second positioning member 542 that is adapted to the center hole of the friction wheel 700. The second positioning member 542 can be inserted into the center hole of the friction wheel 700. This can ensure that the upper cover 540 and the friction wheel 700 rotate concentrically, improve the uniformity of adhesive application, and also play a positioning role for the upper cover 540.

[0028] In this embodiment, the telescopic mechanism includes a second bracket 610, a clamp 620, and a telescopic drive member 630. The telescopic drive member 630 is fixedly mounted on the second bracket 610 and can be a cylinder, electric cylinder, or electric actuator, etc. The clamp 620 is mounted on the output shaft of the telescopic drive member 630 and is used to clamp the glue brush 200. When the friction wheel 700 needs to be coated with glue, the telescopic drive member 630 drives the clamp 620 to move, thereby driving the glue brush 200 to move so that the bristles 210 contact the edge of the friction wheel 700. After the glue application is completed, the telescopic drive member 630 drives the clamp 620 to reset, thereby disengaging the bristles 210 from the friction wheel 700, facilitating the removal and placement of the friction wheel 700.

[0029] In another embodiment, the telescopic mechanism can also consist of a second bracket 610, a motor, a lead screw, a slider, and a clamp 620. The motor drives the lead screw to rotate, the slider is threadedly connected to the lead screw, the slider is slidably mounted on the second bracket 610, and the clamp 620 is fixed on the slider to hold the glue brush 200. This structure also allows the glue brush 200 to move.

[0030] In this embodiment, the clamp 620 includes a U-shaped frame 621, a clamping plate 622, and an elastic element 623. The U-shaped frame 621 is fixedly mounted on the output shaft of the telescopic drive member 630. The clamping plate 622 is movably mounted within the U-shaped frame 621. Specifically, several guide rods 624 are mounted on the clamping plate 622, passing through one side of the U-shaped frame 621 and fixed with a pull handle 625. The guide rods 624 allow the clamping plate 622 to be movably mounted within the U-shaped frame 621; the pull handle 625 facilitates the movement of the clamping plate 622. The elastic element 623 is installed between the clamping plate 622 and one side of the U-shaped frame 621. The elastic element 623 can be a coil spring, compression spring, etc. The glue brush 200 can be clamped between the clamping plate 622 and the side of the U-shaped frame 621 away from the elastic element 623. The pressure of the elastic element 623 causes the clamping plate 622 and the U-shaped frame 621 to apply a clamping force to the glue brush 200, thereby fixing the glue brush 200 and making it easier to remove the glue brush 200.

[0031] In another embodiment, the clamp 620 may also adopt a rigid clamping structure. For example, the clamp 620 includes a first plate and a second plate. The first plate is fixed on the output shaft of the telescopic drive member 630. The first plate and the second plate are connected by several long bolts. The glue brush 200 can be placed between the first plate and the second plate. Then, the bolts are adjusted so that the first plate and the second plate apply a rigid clamping force to the glue brush 200.

[0032] Understandably, although a pressure regulating valve 400 is provided in this embodiment to minimize glue dripping from the brush bristles 210, it is still impossible to completely prevent this situation from occurring. Therefore, to prevent glue from dripping onto the workbench and causing contamination, a waste collection box 640 with an open top is detachably installed on the U-shaped frame 621. The waste collection box 640 can be detachably connected to the U-shaped frame 621 by means of snap-fit ​​connection, plug-in connection, etc. The open side of the waste collection box 640 is located directly below the brush bristles 210, which can collect glue dripping from the brush bristles 210, thereby preventing glue from dripping onto the workbench and causing contamination.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
