Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically to a coating machine adhesive scraping device. Background Technology

[0002] In the prior art, patent CN217450726U discloses a scraping device for a coating machine, which includes a base and a first slide rod. The base has a housing, and a dual-axis motor is fixedly connected inside the housing. Two first bearings are fixedly connected to the inner wall of the housing, symmetrically fixedly. The advantage of this scraping device for a coating machine is that, by incorporating a dual-axis motor, a first bevel gear, a threaded rod, and a connecting rod, when adjusting the position of the scraper, the user controls the dual-axis motor to rotate, which in turn drives the first, second, third, and fourth bevel gears to rotate simultaneously. This, in turn, drives the threaded rod to rotate, which in turn moves the connecting rod and the scraper. Under the action of the dual-axis motor, the first bevel gear, the threaded rod, and the connecting rod, it is easier to synchronously adjust the position of the scraper with higher precision.

[0003] In actual use, although the above-mentioned equipment can replace the scraper in a timely manner, it is troublesome and time-consuming to remove the scraper when there is not much glue adhering to it.

[0004] Therefore, a coating machine adhesive scraping device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a coating machine adhesive scraping device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coating machine scraping device, including a base, on which two glue rollers are rotatably mounted, and two movable seats are movably mounted on the base. Each movable seat has a scraper movably mounted on it, with the glue rollers on the bottom sides of the two scrapers contacting each other. A cleaning mechanism is mounted on the movable seat, contacting the scraper. A spraying mechanism is mounted on the cleaning mechanism, which is installed on the movable seat. The cleaning mechanism includes a limiting rod, which is slidably mounted on the movable seat. A threaded sleeve is mounted on the limiting rod, and an L-shaped rod is mounted on the threaded sleeve. A scraper is mounted on the L-shaped rod, and the scraper contacts the scraper.

[0007] Preferably, a reciprocating lead screw is threaded onto the threaded sleeve, and two positioning blocks are rotatably mounted on the reciprocating lead screw, both of which are mounted on a movable seat.

[0008] Preferably, one of the positioning blocks is equipped with a mounting bracket, and a servo motor is mounted on the mounting bracket by bolts. The servo motor is mounted on one end of a reciprocating lead screw.

[0009] Preferably, the movable seat has a sliding groove, and the limiting rod is slidably installed on the inner wall of the sliding groove.

[0010] Preferably, the spraying mechanism includes a liquid storage tank, which is mounted on a movable base. A booster pump is installed on one side of the liquid storage tank, and an infusion pipe is installed on the booster pump. A spray head is installed on the bottom side of the infusion pipe, and the spray head is adapted to the scraper.

[0011] Preferably, a connecting rod is installed on the L-shaped rod, and a retaining sleeve is installed on the connecting rod, with the retaining sleeve installed on the infusion tube.

[0012] Preferably, the liquid storage tank is equipped with a liquid inlet pipe that is connected to the liquid storage tank, and a sealing plug is installed on the liquid inlet pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model, through the setting of a reciprocating screw, an L-shaped rod, a scraper and a servo motor, after the scraper is moved to a position away from the rubber roller, the servo motor drives the L-shaped rod to reciprocate on the surface of the scraper, so as to conveniently clean the edge of the scraper. At the same time, the V-shaped setting of the scraper not only makes the scraper and the edge of the scraper fit tightly together, cleaning both sides of the scraper at the same time, but also makes the scraper move back and forth stably on the scraper.

[0015] (2) In this utility model, by setting up a liquid storage tank, a booster pump, an infusion pipe and a spray head, when the scraper moves back and forth, the booster pump uses the liquid storage tank to spray the cleaning agent in the liquid storage tank onto the blade of the scraper through the spray head, thereby effectively reducing the adhesiveness of the coating on the blade, thus facilitating the scraper to quickly clean the blade end of the scraper. At the same time, the L-shaped rod drives the infusion pipe on the fixed sleeve to reciprocate on the scraper, thereby spraying the cleaning agent onto different positions of the scraper.

[0024] Example: Please refer to Figure 1-4This utility model provides a technical solution: a coating machine scraping device, including a base 1, on which two glue rollers 2 are rotatably mounted, and two movable seats 3 are movably mounted on the base 1. Each movable seat 3 has a scraper 4 movably mounted on it, with the glue rollers 2 on their evenly spaced bottom sides contacting each other. A cleaning mechanism is mounted on the movable seat 3, contacting the scraper 4. A spraying mechanism is mounted on the cleaning mechanism and installed on the movable seat 3. The cleaning mechanism includes a limiting rod 5, which is slidably mounted on the movable seat 3. A groove 58 is provided on the movable seat 3, and the limiting rod 5 is slidably mounted on the inner wall of the groove 58. A threaded sleeve 51 is mounted on the limiting rod 5, and an L-shaped rod 52 is mounted on the threaded sleeve 51. A... The scraper 53 is in contact with the scraper 4. A reciprocating screw 54 is threaded onto the threaded sleeve 51. Two positioning blocks 55 are rotatably mounted on the reciprocating screw 54. Both positioning blocks 55 are mounted on the movable seat 3. One of the positioning blocks 55 is mounted on a mounting bracket 56. A servo motor 57 is bolted onto the mounting bracket 56. The servo motor 57 is mounted on one end of the reciprocating screw 54. The servo motor 57 drives the reciprocating screw 54 on the positioning block 55 to rotate. The reciprocating screw 54 drives the threaded sleeve 51 on the limit rod 5 to move. The threaded sleeve 51 drives the L-shaped rod 52 to move. The L-shaped rod 52 drives the scraper 53 to reciprocate at the cutting edge of the scraper 4, so that the scraper 53 can clean the coating adhesive on the scraper 4.

[0025] Furthermore, the spraying mechanism includes a storage tank 6, which is mounted on a movable base 3. A booster pump 61 is mounted on one side of the storage tank 6, and an infusion pipe 62 is mounted on the booster pump 61. A spray head 63 is mounted on the bottom side of the infusion pipe 62, and the spray head 63 is compatible with the scraper 4. A connecting rod 64 is mounted on the L-shaped rod 52, and a retaining sleeve 65 is mounted on the connecting rod 64. The retaining sleeve 65 is mounted on the infusion pipe 62.

The booster pump 61 sprays the cleaning agent in the storage tank 6 onto the blade edge of the scraper 4 through the spray head 63 on the infusion pipe 62. At the same time, the L-shaped rod 52 drives the connecting rod 64 to move, and the connecting rod 64 drives the spray head 63 on the retaining sleeve 65 to reciprocate on the scraper 4. This allows the cleaning agent to be sprayed onto different positions on the blade edge of the scraper 4 to reduce the stickiness of the coating adhesive. Meanwhile, the infusion pipe 66 allows for timely replenishment of the cleaning agent in the storage tank 6. The cleaning agent is rosin, and the infusion pipe 62 is composed of a flexible hose and a rigid pipe.

[0026] The working principle is as follows: When applying coating using the rubber roller 2 on the base 1, excessive coating adhesive will adhere to the rubber roller 2. When scraping off the coating adhesive on the rubber roller 2 using the scraper 4 on the moving seat 3, the coating adhesive will adhere to the scraper 4. When it is necessary to clean the coating adhesive on the scraper 4, simply turn on the switch on the booster pump 61. The booster pump 61 will spray the cleaning agent in the storage tank 6 through the spray head 63 on the infusion pipe 62 onto the blade tip of the scraper 4. At the same time, turn on the switch on the servo motor 57. The servo motor 57 will drive the reciprocating screw 54 on the positioning block 55 to rotate. The reciprocating screw 54 will drive the threaded sleeve 51 on the limit rod 5 to move. The threaded sleeve 51 will drive the L-shaped rod 52 to move. The L-shaped rod 52 will drive the scraper 53 to reciprocate at the blade tip of the scraper 4, thereby cleaning the coating adhesive on the scraper 4 using the scraper 53.
