Description

Technical Field

[0001] The utility model provides a glue rolling machine for Velcro fabrics, belonging to the technical field of Velcro fabric glue coating. Background Art

[0002] Velcro, also known as Magic Tape or Velcro, is widely used for the quick connection and separation of various items. It consists of two parts: one side is covered with tiny soft fiber rings, and the other side is covered with countless delicate plastic or nylon hooks. When the two sides are lightly pressed, thousands of tiny hooks will tightly buckle into the fiber rings to achieve an unbreakable connection; when separation is needed, just a light pull and the two can be separated cleanly without leaving any traces. This design is simple and efficient.

[0003] Patent No.: CN208466284U; discloses a Velcro gluing device with a preheating function, including a glue storage tank, a roller fixing frame, a main bracket and a rotating shaft. The glue storage tank is fixed on the main bracket, and a preheating tube is connected to the lower end of the glue storage tank. A heating half tube is wound on the outer wall of the preheating tube. The glue spreading device includes a No. 1 motor and a horizontally placed glue spreading cylinder. The outer sleeve of the glue spreading cylinder is provided with a heating layer. The output shaft of the No. 1 motor extends into one end of the glue spreading cylinder and is connected to the rotating shaft. A spiral blade is provided on the rotating shaft. An internal hollow glue coating disk is provided below one end of the glue spreading device.

[0004] The above patent can control the amount of glue applied and reduce glue waste by setting a glue leveling device, preheat the glue by setting a heating half-tube, and effectively enhance the heat dissipation effect of the embryo tape after gluing by setting an air conditioner. The No. 2 motor drives the glue coating disk to rotate, and the glue brush rotates with the glue coating disk to evenly distribute the glue on the embryo tape. However, in actual use, there are many defects. If the width of the Velcro is greater than the diameter of the glue coating disk, it is difficult to fully coat the Velcro with glue. If the width of the Velcro is not greater than the diameter of the glue coating disk, the glue will be pushed to the glue coating platform by the glue brush, affecting the side of the Velcro that does not need to be coated with glue, and when the Velcro passes through the lower roller and the upper roller, the upper roller will scrape off the excess glue, causing the water to flow around the lower roller, affecting the rotation of the lower roller. When there is too much glue around the lower roller, the side of the Velcro that does not need to be coated with glue will also be contaminated with glue. Utility Model Content

[0005] The technical problem to be solved by the utility model is that it is difficult to fully apply glue to the Velcro cloth of the existing device when it is used, and the glue will adhere to the side of the Velcro cloth that does not need to be applied with glue after the device has been used for a period of time.

[0006] In order to solve the above-mentioned problem, the utility model proposes a technical solution: a glue rolling machine for Velcro fabric, comprising a shell, one side of the shell is provided with an inlet, the other side is provided with an outlet, a feed guide roller is provided on the side of the shell close to the inlet, two parallel support rollers are provided above one side of the feed guide roller, a discharge guide roller is provided on the other side of the two support rollers, hanging plates that can move up and down are respectively provided on both sides above the two support rollers, a glue outlet pipe is provided in the middle of the two hanging plates, a glue frame is provided below the two support rollers in the shell, the glue frame is connected to a pump body, the pump body is connected to the glue outlet pipe, an observation window for observing the height of the two hanging plates is provided on one side of the shell, and the length of the inlet is less than the length of the support rollers and the hanging plates.

[0007] As an improvement, the lengths of the inlet and outlet are the same, and the lengths of the feed guide roller, support roller, discharge guide roller, hanging plate, and discharge hose are the same;

[0008] As an improvement, the surface of the discharge guide roller is covered with a semiconductor refrigeration sheet;

[0009] As an improvement, the lower ends of the two hanging plates are arc-shaped, and the outer shell is located above the hanging plates and cylinders are respectively arranged on both sides, and the cylinder shafts of the cylinders pass through the outer shell to connect the hanging plates;

[0010] As an improvement, a heating wire is provided on the inner wall of the rubber frame, and a one-way valve is provided in the connecting pipes between the rubber frame and the pump body, and between the pump body and the rubber outlet pipe;

[0011] As an improvement, the middle of the outlet is located at the upper end of the discharge guide roller, and the middle of the inlet is located at the upper end of the feed guide roller.

[0012] Beneficial effects of the utility model:

[0013] By designing the length of the inlet to be smaller than the length of the supporting roller and the hanging plate, the Velcro cloth entering the device can be fully coated with glue when the device is coating the Velcro cloth, and after coating the glue, the hanging plate close to the outlet can scrape off excess glue, and the scraped glue will protrude from the hanging plate at both ends of the Velcro cloth and fall back into the glue frame below, and then be transported to the glue outlet pipe through the pump body to coat the Velcro cloth with glue.

When the Velcro cloth moves, excess glue will be scraped off by the scraper 5 close to the outlet 102, and then fall back into the glue frame 7 below from both sides. At the same time, the glue will flow to the side close to the inlet 101, and will then be scraped off by the scraper 5 close to the inlet 101, and will also fall back into the glue frame 7 below. The glue falling into the glue frame 7 will be heated to increase fluidity, and then reused. When the Velcro cloth after glue coating passes through the discharge guide roller 4, the glue on it will be cooled to room temperature, so that it will not drip at will.
