Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive machine technology, and in particular to a double-roller hot melt adhesive machine capable of removing adhesive from the roller body. Background Technology

[0002] Hot melt glue machines are mainly used for applying glue to materials such as pearl cotton, EVA, and cardboard for bonding and shaping. A double-roller hot melt glue machine delivers molten glue via a dispensing roller and uses a pressure roller to ensure the hot melt glue is applied evenly to a certain thickness.

[0003] After the two-roller hot melt glue machine finishes applying glue, hot melt glue residue remains on the surfaces of the pressure roller and the glue application roller, which hinders subsequent glue application. Current production methods use a back-and-forth sliding scraper to clean the hot melt glue from the outside of the rollers, but because the thickness of the residual hot melt glue varies across different areas of the roller surface, it cannot be guaranteed that the hot melt glue will be completely removed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a double-roller hot melt adhesive machine capable of removing adhesive from the roller body.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A servo motor for controlling the rotation of the lead screw is provided at one end of the support plate, and the servo motor is externally connected to a control power supply.

[0011] A sliding plate is slidably mounted on the mounting platform. A movable plate is rotatably mounted on the front side of the mounting platform in the sliding direction of the sliding plate via a fixed shaft. A scraper is provided at the front of the movable plate. The scraper is obliquely positioned on the side facing the roller and fits against the surface of the roller. A fixed column is provided on the rear surface of the movable plate. An oblique guide groove is provided on the surface of the sliding plate.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] In this embodiment, refer to Figure 1-3 A double-roller hot melt glue machine capable of removing adhesive from the roller surface includes a hot melt glue machine body 1, a mounting platform 3 on the hot melt glue machine body 1, electrical control boxes 5 on both sides of the mounting platform 3, and a pressure roller 6 and a glue dispensing roller 7 arranged vertically and vertically between the two electrical control boxes 5. Positioning side plates 4 are respectively provided on both sides of the mounting platform 3 of the hot melt glue machine body 1. The hot melt glue machine body 1 is equipped with a control switch and a display screen 2. In the prior art, when the hot melt glue machine body 1 is working normally, the switch is turned on, the glue dispensing roller 7 dispenses glue, and the pressure roller 6 presses the cardboard. As the roller rotates, it ensures that the glue can be smoothly coated onto the surface of the cardboard.

[0022] The side of the electrical control box 5 is provided with a double-layer support plate 8. The upper and lower support plates 8 are respectively installed on the outer wall of the electrical control box 5 through their respective connecting ribs, and the upper and lower support plates 8 maintain a fixed distance, do not contact each other, and do not affect each other.

[0023] A mounting platform 11, which moves back and forth along a straight line, is mounted on the support plate 8 via a screw drive, as shown in the attached figure. Figure 2 As shown, a lead screw 9 is rotatably mounted on the inner side of the support plate 8. The lead screw 9 is arranged along the length of the support plate 8, and a nut pair is threadedly connected to the lead screw 9. The nut pair is fixedly connected to the mounting platform 11 above it. A servo motor 10 is provided at one end of the support plate 8 to control the rotation of the lead screw 9. The servo motor 10 is externally powered. The servo motor 10 drives the lead screw 9 to rotate, thereby achieving the purpose of moving the mounting platform 11 back and forth. The servo motors 10 on the upper and lower layers can be controlled to start separately or synchronously.

[0024] A sliding plate 13 is mounted on the mounting platform 11, combined with the attached... Figure 2 As can be seen, a cylinder 12 is installed on the mounting platform 11, and the front end of the pneumatic rod at the output end of the cylinder 12 is fixedly connected to the slide plate 13 via a connecting bracket 20. A track 14 is provided on the platform 11 for the slide plate 13 to slide linearly. The slide plate 13 slides back and forth along the track 14 by being pushed by the cylinder 12.

[0025] A movable plate 16 is rotatably mounted on the mounting platform 11 on the front side of the sliding plate 13 via a fixed shaft 15. A scraper 17 is provided at the front of the movable plate 16. A fixed post 19 is provided on the rear surface of the movable plate 16. The sliding plate 13 has an oblique guide groove 18 on its surface. The fixed post 19 is embedded in the guide groove 18 and slides along its groove. It should be noted that the guide groove 18 is obliquely arranged, forming a certain angle with the forward direction of the sliding plate 13.

[0026] When cylinder 12 pushes slide plate 13 forward or backward, the fixed post 19 at the rear of movable plate 16 slides along guide groove 18. The middle part of movable plate 16 is rotatably connected to the surface of mounting platform 11 via fixed shaft 15. Therefore, as slide plate 13 moves back and forth, movable plate 16 also swings around fixed shaft 15. Consequently, scraper 17 at the front of movable plate 16 approaches the roller surface until it adheres to the roller. Since the position and thickness of the adhesive on the surface of pressure roller 6 or dispensing roller 7 differ, adjusting the contact position of scraper 17 with the roller ensures smooth removal of adhesive. During roller rotation, in conjunction with the back-and-forth movement of mounting platform 11, adhesive on the surfaces of pressure roller 6 and dispensing roller 7 can be completely removed, ensuring the cleanliness of the roller and guaranteeing smooth subsequent adhesive application.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
