Description

Technical Field

[0001] This utility model relates to the field of rubber coating technology, and in particular to a dispensing device for an easily adjustable rubber adhesive enhancer. Background Technology

[0002] Rubber adhesion promoters are additives used in rubber bonding processes to improve the curing properties of the adhesive. However, existing rubber coating equipment still has certain drawbacks.

[0003] A search revealed that application number CN201821774266.1 discloses a height-adjustable rubber adhesive additive dispensing device, comprising a base, a conveyor belt, and a second rotating shaft. A lower support column is mounted on the upper side of the base, and a hydraulic cylinder is housed inside the lower support column. A telescopic rod is housed inside the hydraulic cylinder, and an upper support column is mounted on the upper end of the telescopic rod. The conveyor belt is located on the upper side of the base, and a first motor is mounted on the right side of the conveyor belt. A second motor is mounted on the upper side of the mixing tank, and a discharge pipe is mounted on the lower side of the discharge port. A discharge box is located at the lower right end of the discharge pipe, and a roller is mounted on the inner side of the connecting frame. This height-adjustable rubber adhesive additive dispensing device, equipped with a roller, allows the discharge box to feed the adhesive into multiple conduits inside the discharge funnel. The adhesive then flows through these conduits onto the entire outer surface of the roller, directly applying the adhesive to the rubber via the roller, resulting in uniform adhesive application and improved work efficiency.

[0004] The above solution has the advantages of adjustable coating height, dual-inlet feeding, and uniform coating. However, in actual use, due to the difference in the size of the rubber to be bonded, the glue liquid uniformly coated on the coating roller is wasted, which is not conducive to the targeted adjustment of the coating range.

[0005] To address this, a dispensing device for an easily adjustable rubber adhesion promoter is proposed, which has the advantage of conveniently adjusting the coating range according to the rubber size, thereby solving the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an easily adjustable dispensing device for rubber adhesive enhancers.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a dispensing device for an easily adjustable rubber adhesive enhancer, comprising a dispensing table, two vertical rods welded to the top surface of the dispensing table, and a dispensing frame fitted onto the surface of the two vertical rods. A vertical cylinder is welded to the left and right sides of the dispensing frame, and the two vertical cylinders are respectively connected to the two vertical rods of the dispensing table. A dispensing roller is installed between the two vertical cylinders via a bearing seat. A glue tank is fixed to the top of the dispensing frame, and a glue inlet is connected to the upper left side of the glue tank, and an enhancer inlet is connected to the upper right side of the glue tank. An electric valve is installed on the surface of the nozzle at the bottom of the glue tank, and a transition glue box is connected to the bottom of the nozzle. Multiple glue tubes are connected to the bottom of the transition glue box, and a manual valve is installed on the surface of each glue tube. Side openings are provided at the bottom ends of the multiple glue tubes, and brush strips are fixed inside the side openings by screws, with the brush strips in contact with the dispensing rollers.

[0008] As a further description of the above technical solution: the lower surfaces of the two vertical cylinders of the glue applicator are each threaded with a plum blossom knob, and the surface of the vertical rod is provided with several through holes at equal intervals, one of which is connected to the plum blossom knob of the vertical cylinder.

[0009] As a further description of the above technical solution: the bottom of the transition box is provided with a V-shaped concave surface, and the V-shaped concave surface is connected to the top of multiple tubes.

[0010] As a further description of the above technical solution: the glue tank is a cylindrical structure, and a stirring motor is fixedly installed on the top of the glue tank. The output end of the stirring motor passes through the glue tank and a stirring paddle is fixedly installed thereon. Several sets of stirring rods are installed at equal intervals on the surface of the stirring paddle.

[0011] As a further description of the above technical solution: two arc-shaped shells are symmetrically welded to the bottom end of the hose corresponding to the side opening, and the height of the two arc-shaped shells is less than the thickness of the brush strip.

[0012] As a further description of the above technical solution: the roller shaft at the left end of the coating roller is fitted with a bearing, and the bearing is rotatably connected to the vertical cylinder on the left side of the coating frame.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, multiple adhesive tubes are connected to the bottom of the transition box of the adhesive tank. Each adhesive tube is equipped with a manual valve and a brush strip. When adhesive is dispensed from the adhesive tank, the manual valves of several adhesive tubes at the bottom of the transition box are opened, allowing the adhesive to be drawn out of the adhesive tank and then flow to the coating roller through the opening at the bottom of each adhesive tube. During this process, since a brush strip is horizontally installed at the opening at the bottom of each adhesive tube, the adhesive flowing out of the adhesive tube is evenly brushed onto the coating roller by the brush. This ensures that the width of the coating roller carrying the adhesive matches the size of the rubber to be coated. Combined with the setting of adhesive inlet and additive inlet, the dual-inlet feeding is satisfied while facilitating the adjustment of the coating range according to the size of the rubber.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] According to an embodiment of the present invention, a dispensing device for a rubber adhesive enhancer that is easy to adjust is provided.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-3As shown, an adjustable rubber adhesive enhancer dispensing device according to an embodiment of the present invention includes a coating table 1. Two vertical rods 12 are welded to the top surface of the coating table 1, and a coating frame 2 is fitted onto the surface of the two vertical rods 12. A vertical cylinder 10 is welded to the left and right sides of the coating frame 2, and the two vertical cylinders 10 are respectively connected to the two vertical rods 12 of the coating table 1. A coating roller 3 is installed between the two vertical cylinders 10 via a bearing seat. A glue tank 4 is fixed to the top of the coating frame 2, and a glue inlet 5 is connected to the upper left side of the glue tank 4, while an enhancer inlet 6 is connected to the upper right side of the glue tank 4. An electric valve 7 is installed on the surface of the nozzle at the bottom of the glue tank 4, and a transition glue box 8 is connected to the bottom of the nozzle. Multiple glue tubes 9 are connected to the bottom of the transition glue box 8, and a manual valve 17 is installed on the surface of each glue tube 9. Each of the multiple adhesive tubes 9 has a side opening 18 at its bottom, and a brush strip 19 is fixed inside the side opening 18 by screws. The brush strip 19 inside the side opening 18 is in contact with the adhesive roller 3. Regarding the electric valve 7 and the stirring motor 15, we only use them in this patent without improving their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method can be adjusted and operated according to the requirements of their instruction manual, so they will not be described in detail here. Both the electric valve 7 and the stirring motor 15 are equipped with their matching control switches. The installation position of the control switches can be selected according to the actual use requirements to facilitate the operation and control of the operator. The manual valve 17 can not only facilitate the flow of adhesive but also adjust the flow rate of adhesive. The adhesive tubes 9 are made of rigid PVC material instead of rubber.

[0023] In one embodiment, the lower surfaces of the two vertical cylinders 10 of the coating frame 2 are each threaded with a plum blossom knob 11. The surface of the vertical rod 12 is provided with several through holes 13 at equal intervals, and one of the through holes 13 is connected to the plum blossom knob 11 of the vertical cylinder 10. By pulling the coating frame 2, the vertical cylinders 10 on the left and right sides of the coating frame 2 are slid along the surfaces of the two vertical rods 12 of the coating table 1. When the gap between the coating roller 3 and the coating table 1 matches the actual thickness of the rubber to be coated, the plum blossom knob 11 on the lower surface of the vertical cylinder 10 is rotated so that the plum blossom knob 11 is connected to one of the through holes 13 on the surface of the vertical rod 12. This makes it easy to perform coating operations for rubber of different thicknesses.

[0024] In one embodiment, the bottom of the transition glue box 8 is provided with a V-shaped concave surface 14, and the V-shaped concave surface 14 is connected to the top of multiple glue tubes 9. Through the provision of the V-shaped concave surface 14, the glue liquid in the transition glue box 8 can be fully discharged under the action of gravity.

[0025] In one embodiment, the adhesive tank 4 is a cylindrical structure, and a stirring motor 15 is fixedly installed on the top of the adhesive tank 4. A stirring paddle 16 is fixedly installed through the output end of the stirring motor 15 through the adhesive tank 4. Several sets of stirring rods are equidistantly installed on the surface of the stirring paddle 16. By starting the stirring motor 15 of the adhesive tank 4, the stirring paddle 16 fixed at the output end of the stirring motor 15 mixes and stirs the adhesive and rubber adhesive enhancer.

[0026] In one embodiment, two arc-shaped shells are symmetrically welded to the bottom end of the tube 9 corresponding to the side opening 18, and the height of the two arc-shaped shells is less than the thickness of the brush strip 19. The arc-shaped shells facilitate the flow of adhesive and increase the tightness between the tube and the brush strip 19, making it easier for the adhesive to flow to the brush strip 19 and thus making it easier to brush the adhesive onto the surface of the coating roller 3.

[0027] In one embodiment, a bearing is installed on the roller shaft at the left end of the coating roller 3, and the bearing is rotatably connected to the vertical cylinder 10 on the left side of the coating frame 2. The surface of the vertical cylinder 10 has a vertical hole corresponding to the vertical rod 12, and the installation position of the bearing is offset from the vertical hole so as not to interfere with the installation of the vertical rod 12.

[0028] Working principle:

[0029] In use, first, inject the adhesive into the adhesive tank 4 through the adhesive inlet 5, then inject the rubber adhesion promoter into the adhesive tank 4 through the promoter inlet 6. Next, start the stirring motor 15 in the adhesive tank 4, causing the stirring paddle 16 fixed at the output end of the stirring motor 15 to mix the adhesive and rubber adhesion promoter. When dispensing adhesive, open the manual valves 17 on the surface of several adhesive tubes 9 according to the actual size of the rubber to be coated, allowing the opened adhesive tubes 9 to draw the adhesive from the adhesive tank 4, which then flows through the opening at the bottom of each adhesive tube 9 to the coating roller 3. During this process, a brush is horizontally installed at the opening at the bottom of each adhesive tube 9. The adhesive flowing from the adhesive tube 9 is evenly brushed onto the coating roller 3 by the brush, and then the adhesive carried by the coating roller 3 is applied to the surface of the rubber to be coated. When it is necessary to adjust the height of the coating roller 3, the vertical cylinders 10 on the left and right sides of the coating frame 2 are slid along the surfaces of the two vertical rods 12 of the coating table 1 by pulling the coating frame 2. When the gap between the coating roller 3 and the coating table 1 matches the actual thickness of the rubber to be coated, the plum blossom knob 11 on the lower surface of the vertical cylinder 10 is rotated so that the plum blossom knob 11 is connected to one of the through holes 13 on the surface of the vertical rod 12. This makes it easy to perform coating operations for rubber of different thicknesses.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
