DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution of a coaxial gluing mechanism for a plate: a coaxial gluing mechanism for a plate, comprising a fixed seat 1 installed on a plate edge banding machine, a glue storage box 2 is installed at the lower end of the rear side of the fixed seat 1, a detachable box cover 22 is installed at the rear side of the upper end of the glue storage box 2, and a plurality of heating tubes 21 for heating the glue liquid inside the glue storage box 2 are distributed at the bottom of the glue storage box 2, the inner bottom end of the glue storage box 2 is inclined, the purpose is to better gather the glue liquid to the glue inlet 11, so as to enter the glue upper cavity 13, the inclined end of the bottom of the glue storage box 2 corresponds to the glue inlet 11, glue liquid can be added to the glue storage box 2 by opening the box cover 22, and during use, the glue liquid inside the glue storage box 2 can be heated by the heating tube 21 to avoid the glue liquid from solidifying due to the low ambient temperature and affecting the gluing effect.

[0025] like Figure 2 , 3 As shown in Figure 6, an upper glue cavity 13 is provided at the lower end of the interior of the fixed seat 1, an upper pressure cover 5 is installed on the top of the fixed seat 1, and a lower pressure shaft 4 is installed at the bottom of the fixed seat 1. A rotating rod 41 is installed through the lower pressure shaft 4 at the bottom of the fixed seat 1, and the top of the rotating rod 41 is located in the upper glue cavity 13 and is connected to a spiral glue roller 43. A glue inlet 11 is provided at the lower end of the rear side of the fixed seat 1 corresponding to the glue storage box 2. When the glue liquid enters the upper glue cavity 13 from the glue inlet 11, the spiral glue roller 43 is driven to rotate by the rotating rod 41, so that the glue liquid in the upper glue cavity 13 can be lifted to the glue coating roller 42 for use by the glue coating roller 42 to coat the glue.

[0026] like Figure 3 ,5 As shown in Figure 6, a glue return chamber 15 is provided at the upper end of the interior of the fixing seat 1, and a glue return port 12 connected to the glue return chamber 15 is provided on the rear side of the fixing seat 1, which is located above the glue inlet 11. The top end of the spiral glue roller 43 is located in the glue return chamber 15 and is connected to a glue coating roller 42. The glue coating roller 42 is in contact with the side edge of the plate and brushed, so that the side edge of the plate can be coated with glue. A scraper 14 is provided inside the glue return chamber 15, which is located at the rear side of the glue coating roller 42. There is a gap between one side of the scraper 14 and the surface of the glue coating roller 42. The scraper 14 can be used to scrape the glue on the surface of the glue coating roller 42 to ensure the uniformity of the glue on the surface of the glue coating roller 42, thereby ensuring the uniformity of the glue coating on the side edge of the plate.

[0027] like Figure 2 and 6 As shown, a glue collecting groove 3 connected to the glue return chamber 15 is provided at the lower end of the glue coating roller 42 on the front side of the fixed seat 1, and the glue inlet 11 and the glue return port 12 are both connected to the interior of the glue storage box 2, so that the glue in the glue storage box 2 can enter the upper glue chamber 13 from the glue inlet 11, and the glue in the glue return chamber 15 can also flow back to the glue storage box 2 from the glue return port 12, so as to recover the glue. The glue collecting groove 3 is connected to the interior of the glue return chamber 15, and an opening is provided at the upper side of the fixed seat 1 corresponding to the glue coating roller 42 above the glue collecting groove 3. The outer surface of the glue coating roller 42 extends to the opening, and the bottom of the glue collecting groove 3 is inclined. The bottom of the glue collecting groove 3 is inclined, so that the glue overflowing when the glue coating roller 42 coats the side of the plate falls into the glue collecting groove 3, and then flows back to the glue return chamber 15, and finally flows back to the interior of the glue storage box 2.

[0028] like Figure 6 As shown, the bottom end of the rotating rod 41 is connected to the driving motor, and the rotating rod 41 is rotationally connected to the lower pressure shaft 4, the rotating rod 41 and the spiral gluing roller 43 and the gluing roller 42 are of an integrated design and are located on the same vertical center line, and the top end of the gluing roller 42 is rotationally connected to the upper pressure cover 5. The rotating rod 41 is driven by an external driving motor to rotate, thereby driving the spiral gluing roller 43 and the gluing roller 42 to rotate synchronously. On the one hand, the glue in the gluing chamber 13 can be lifted to the gluing roller 42, and on the other hand, the gluing roller 42 can be used to simultaneously apply glue to the side of the plate.

[0029] The working principle of the utility model is as follows: the fixing seat 1 is fixed to the plate edge banding machine by bolts, so that the glue coating roller 42 corresponds to the side of the plate. During the plate conveying process, the side of the plate will contact the glue coating roller 42, and the glue coating roller 42 is used to apply glue to the side of the plate;

[0030] During the gluing process, the driving motor drives the rotating rod 41 to rotate, thereby synchronously rotating the spiral gluing roller 43 and the gluing roller 42. The spiral gluing roller 43 will lift the glue in the gluing cavity 13 onto the gluing roller 42, and the gluing roller 42 will be used to apply glue to the side of the plate;

[0031] While the glue coating roller 42 is applying glue, the scraper 14 in the glue return chamber 15 will scrape the surface of the glue coating roller 42 to ensure the uniformity of the glue on the surface of the glue coating roller 42. The excess glue scraped off will flow into the glue return chamber 15, and then flow back to the glue storage box 2 through the glue return port 12. In addition, the glue overflowed when the glue coating roller 42 is applying glue to the side of the plate falls into the glue collecting groove 3, and then flows back to the inside of the glue storage box 2 through the glue return chamber 15.

[0032] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
