Technical Field
[0001] This application belongs to the field of polishing cloth wheel production technology, and particularly relates to a glue coating device. Background Technology
[0002] In the production process of polishing cloth wheels, one of the key steps is to bond and fix the pre-formed cylindrical cloth wheel (composed of a wood core and multiple layers of cloth) to a circular wooden board. This bonding process directly affects the overall strength, dynamic balance performance, and subsequent machining accuracy of the mounting holes of the cloth wheel product.
[0003] Currently, most bonding processes involve operators manually applying glue to the end face of round wooden boards. This method is inefficient, and because round wooden boards contain some wood chips after processing, the end face must be cleaned before applying glue, which cannot be fully guaranteed by manual glue application. Utility Model Content

[0005] To achieve the above objectives, the present invention employs the following technology: An adhesive applicator for applying adhesive to the end face of a circular wooden board, comprising: The mounting box has a rectangular structure with one end open. A rectangular disc faces the length of the mounting box and is located between the upper and lower ends of the mounting box; the rectangular disc is movable along the length of the mounting box, and a placement groove for placing a circular wooden board parallel to it is opened in the middle of the top surface; a first mating part and a second mating part are respectively provided at both ends of the rectangular disc; Two mounting blocks are respectively located on the two inner sides of the mounting box above the rectangular disk, and between the first mating part and the second mating part; the mounting blocks are slidably fitted with elastically loaded guide rods that are perpendicular to the rectangular disk; the lower ends of the two guide rods are vertically connected to a strip plate arranged along the width direction of the rectangular disk, and the bottom surface of the strip plate is provided with brushes in the same direction for cleaning the top surface of the circular wooden board. A one-way locking mechanism is provided on the side of the two mounting blocks facing the second mating part to lock the downward movement of the guide rod; The glue delivery tube, with its glue outlet located inside the mounting box, is used to discharge glue onto the top surface of the round wooden board. The glue scraping mechanism, located inside the mounting box, is used to scrape the glue evenly onto the top surface of the round wooden board; When the rectangular disc moves below the adhesive scraping mechanism, the first mating part is used to lift the guide rod; when the rectangular disc moves out of the mounting box, the second mating part is used to activate the one-way locking mechanism to release the one-way locking of the guide rod.
[0006] The beneficial effects of this utility model are as follows: By using the mounting block, guide rod, and brush, and through the cooperation of the first mating part with the guide rod and the second mating part with the one-way locking mechanism, each round wooden board entering the mounting box can be cleaned by the brush. Before the round wooden board with glue is removed from the mounting box, the brush can automatically rise to avoid contact with the glue on the top surface of the round wooden board. The entire glue application process has a high degree of automation, which can effectively improve glue application efficiency and ensure the cleanliness of the glued end face of each round wooden board, thus improving the glue application quality.

Detailed Implementation
[0012] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.
[0013] This application provides an adhesive application device, such as... Figures 1-4 As shown, it includes: mounting box 1, rectangular plate 2, two mounting blocks 3, one-way locking mechanism 4, glue delivery tube 5, and glue scraping mechanism 6.
[0014] Among them, such as Figure 1 As shown, the mounting box 1 has a cuboid structure and one end is open; the two inner sides of the mounting box 1 are also provided with guide rails 11 arranged along the length direction, one end of which extends out of the open end face of the mounting box 1 by a predetermined length.
[0015] like Figure 1 , Figure 3 , Figure 4 As shown, the rectangular disk 2 faces the length direction of the mounting box 1 and is located parallel between the upper and lower end faces of the mounting box 1; the two sides of the rectangular disk 2 are respectively slidably fitted on the corresponding guide rails 11, and the above-mentioned predetermined length is adapted to the rectangular disk 2 so that the rectangular disk 2 can be completely pulled out of the mounting box 1; a placement groove 21 for placing a circular wooden board is opened in the middle of the top surface of the rectangular disk 2; the two ends of the rectangular disk 2 are respectively provided with a first mating part 22 and a second mating part 23.
[0016] like Figures 1-4 As shown, two mounting blocks 3 are respectively disposed on the two inner sides of the mounting box 1 above the rectangular disk 2, and located between the first mating part 22 and the second mating part 23; a guide rod 31 perpendicular to the rectangular disk 2 is slidably passed through the mounting block 3; a through hole 34 is opened on the side of the mounting block 3 facing the first mating part 22, penetrating the guide rod 31 and the bottom surface of the mounting block 3; a strip groove 35 arranged along the length direction is opened on the side of the guide rod 31 facing the first mating part 22, which connects to the through hole 34; the strip groove 35 The device includes an internal mounting bracket with rollers 36 mounted on it. The top of the guide rod 31 has a support plate 37 parallel to the rectangular disk 2. The support plate 37 is connected to the top surface of the mounting block 3 by a helical spring 38 arranged perpendicular to the rectangular disk 2. The first mating part 22 is used to pass through the through hole 34 and enter the strip groove 35 to lift the rollers 36. The lower ends of the two guide rods 31 are vertically connected to a strip plate 32 arranged along the width direction of the rectangular disk 2. The bottom surface of the strip plate 32 is provided with a brush 33 in the same direction for cleaning the top surface of the circular wooden board. like Figure 3 and Figure 4 As shown, the one-way locking mechanism 4 includes a ratchet rack 41 disposed on the side of the guide rod 31 facing the second mating part 23. The ratchet rack 41 is disposed along the length direction of the guide rod 31 and the tooth surface faces the second mating part 23. The mounting block 3 is rotatably provided with a mounting seat on the side facing the second mating part 23, and a pawl 42 is provided thereon. One end of the pawl 42 is connected to the mounting block 3 through a spring plate 43. The spring plate 43 is used to elastically load the braking end of the pawl 42 between the ratchet teeth of the ratchet rack 41 to one-way lock the downward movement of the guide rod 31. The second mating part 23 is used to press down one end of the pawl 42 to separate the braking end of the pawl 42 from the ratchet rack 41.
[0017] like Figures 1-3 As shown, the glue outlet of the glue delivery pipe 5 is located inside the mounting box 1 and is used to discharge glue on the top surface of the circular wooden board. The input end of the glue delivery pipe 5 is connected to the glue delivery pump 51 located at the top of the mounting box 1. The glue delivery pump 51 is connected to the glue storage tank 52 located at the top of the mounting box 1 through a pipe.
[0018] like Figures 1-3As shown, the glue scraping mechanism 6 includes a rotating shaft 61 located inside the mounting box 1 and arranged perpendicular to the rectangular disk 2. The rotating shaft 61 is rotatable around its own axis. A strip scraper 62 is vertically connected to the lower end of the rotating shaft 61. Its length is adapted to the radius of the circular wooden board and is used to scrape the glue evenly on the top surface of the circular wooden board. The rotating shaft 61 is driven by a motor 63 located on the top surface of the mounting box 1.
[0019] In application, the operator pulls the rectangular disc 2 out of the mounting box 1, causing the second mating part 23 to press down on one end of the pawl 42. The one-way locking mechanism 4 releases the lock on the guide rod 31, and the brush 33 falls freely. The projection of the circular wooden board on the placement slot 21 along the length of the mounting box 1 is located on the brush 33. Then, the operator pushes the rectangular disc 2 with the circular wooden board placed into the mounting box 1. During the pushing process, the brush 33 will pass over the glued end face of the circular wooden board and clean it to ensure the end face is clean. When the circular wooden board has been cleaned and moved to the point where its axis coincides with the axis of the rotating shaft 61, the first mating part 22 lifts the roller 36, causing the brush 33 to rise. Since the second mating part 23 does not engage the pawl 42 at this time, the brush 33 will not rise. After the brush 33 rises, it will be fixed by the action of the pawl 42 and the ratchet 41; the glue pump 51 pumps the glue from the glue tank 52 and discharges it to the top surface of the circular wooden board through the glue pipe 5; the motor 63 drives the rotating shaft 61, and the rotating shaft 61 drives the strip scraper 62 to scrape the glue evenly on the top surface of the circular wooden board; finally, the operator pulls out the rectangular plate 2. During the pulling process, since the brush 33 is fixed above the circular wooden board, the brush 33 will not come into contact with the end face of the circular wooden board coated with glue; when the rectangular plate 2 is fully pulled out, the second mating part 23 presses down on one end of the pawl 42, thereby releasing the one-way lock on the guide rod 31, and the brush 33 falls down to clean the end face of the next circular wooden board entering the mounting box 1.
[0020] By setting up the mounting block 3, guide rod 31, and brush 33, and through the cooperation of the first mating part 22 with the guide rod 31 and the cooperation of the second mating part 23 with the one-way locking mechanism 4, the circular wooden board that enters the mounting box 1 can be cleaned by the brush 33 each time. Before the circular wooden board that has been coated with glue is removed from the mounting box 1, the brush 33 can automatically rise to avoid contact with the glue on the top surface of the circular wooden board. The entire glue coating process has a high degree of automation, which can effectively improve the glue coating efficiency and effectively ensure the cleanliness of the glue coating end face of each circular wooden board, thereby improving the glue coating quality.
[0021] Preferred, such as Figure 2 As shown, there are two helical springs 38 on each mounting block 3, located on both sides of the guide rod 31, to ensure the stability of the guide rod 31 during operation.
[0022] Preferred, such as Figure 1As shown, the rectangular disk 2 can be fitted to the guide rail 11 by using pulleys and grooves to make the rectangular disk 2 run smoothly and facilitate the operator to push and pull it back and forth.
[0023] Specifically, such as Figure 3 and Figure 4 As shown, the first mating part 22 can be configured as two lifting blocks with inclined surfaces, located on both sides of one end of the rectangular disk 2; the second mating part 23 can be configured as two push plates, located on both sides of the other end of the rectangular disk 2.
[0024] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
