DETAILED DESCRIPTION

[0036] The technical solution of the utility model will be described clearly and completely below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] The utility model embodiment specifically provides a plywood production glue coating machine, please refer to Figure 1 , including a machine body 1, a drying chamber 2 and a scraping assembly 3.

[0038] Among them, a conveying roller 11 is installed on the body 1, and the body 1 conveys the plywood through the conveying roller 11. The body 1 is also equipped with a glue coating roller 12 for coating the plywood with glue. The glue coating roller 12 is a commonly used device on the existing glue coating machine. By cooperating with the conveying roller 11, after the plywood is conveyed by the conveying roller 11, the upper surface of the plywood can be coated with glue by the glue coating roller 12, thereby meeting the gluing operation needs of the plywood.

[0039] The heating chamber 2 and the glue scraping assembly 3 are respectively located at the front and rear ends of the glue coating roller 12. After being heated by the heating chamber 2, the plywood is sent into the glue coating roller 12 for glue coating, and the glue coating thickness is automatically controlled by the glue scraping assembly 3.

[0040] For details, please refer to Figure 1 and Figure 2 The drying chamber 2 includes a chamber body 21, a heat extraction fan 22, an exhaust fan 23 and a heater 24. The bottom of the chamber body 21 is fixed to the machine body 1. The heat extraction fan 22 and the exhaust fan 23 are respectively embedded and fixed on the left and right sides of the chamber body 21. The heater 24 is fixed on the outside of the chamber body 21. The heat generated by the heater 24 is blown into the chamber body 21 by the heat extraction fan 22, and the hot air is discharged by the exhaust fan 23, so as to form a heat flow in the chamber body 21 to heat the surface of the plywood, so as to prevent the surface of the plywood from being too cold and affecting the gluing effect of the glue.

[0041] During implementation, the heater 24 includes an outer shell 241, a heating wire 242 and a through hole 243. The outer side of the outer shell 241 is fixed to the warehouse body 21, and the heating wire 242 is fixed inside the outer shell 241. Heat is generated by the heating wire 242. A through hole 243 communicating with the interior of the warehouse body 21 is opened on the outer side of the outer shell 241. The heat extraction fan 22 blows out the heat through the through hole 243, so that the glue-coated surface of the plywood can be heated by hot air before being transported.

[0042] For further information, please refer to Figure 1 The scraper assembly 3 includes a scraper 31, a measuring assembly 32 and a displacement assembly 33. The measuring assembly 32 is installed at both ends of the scraper 31. The downward displacement height of the scraper 31 is measured by the measuring assembly 32. When the scraper 31 is idle, there is a height gap between its bottom and the upper surface of the conveyed plywood. When the glue coating thickness needs to be controlled, the controlled glue coating thickness = the height gap at the bottom of the scraper 31 - the moving distance;

[0043] The bottom end of the displacement component 33 is fixed to the machine body 1, and the displacement component 33 is fixed to the outer side of the scraper 31, so that the displacement component 33 drives the scraper 31 to move linearly up and down, so that the scraper 31 can move up and down to reasonably adapt to the glue layer thickness required by the plywood.

[0044] During implementation, the range component 32 is a linear editor to accurately measure and control the movement of the scraper 31. The range component 32 is remotely connected to the production line controller to send the detection data to the controller, so that the controller can make corresponding records and the operator can operate conveniently.

[0045] For details, please refer to Figure 3The measuring range component 32 includes a measuring scale 321 and an editor 322. The outer side of the measuring scale 321 is fixed to the body 1. The editor 322 is slidably arranged on the side of the measuring scale 321 close to the scraper 31, and the outer side of the editor 322 is fixedly connected to the scraper 31, so that when the scraper 31 moves downward, it can drive the editor 322 to move synchronously, so that the measuring scale 321 can obtain the moving distance of the scraper 31, and the same is true when the scraper 31 moves upward.

[0046] For further information, please refer to Figure 1 and Figure 3 The displacement assembly 33 includes a support plate 34, a pushing assembly 35 and an elastic assembly 36.

The upper and lower ends of the elastic assembly 36 are respectively fixed to the scraper 31 and the support plate 34, so that the scraper 31 can move downward by the pressure of the pushing assembly 35 and approach the plywood to limit the thickness of the glue layer. When the pressure of the scraper 31 is cancelled, the scraper 31 can move upward through the elastic assembly 36, so that the scraper 31 meets the need of moving up and down to adjust the scraping thickness.

[0047] For details, please refer to Figure 4 The pushing assembly 35 includes a rotating rod 351, a pressure rod 352, a reducer 353 and a motor 354. The left and right ends of the rotating rod 351 are rotatably installed on the support plate 34. The outer bottom end of the pressure rod 352 is in contact with the scraper 31, so that the pressure rod 352 is driven to press the scraper 31 downward after the rotating rod 351 rotates, so that the scraper 31 is forced to move downward. The reducer 353 is fixed on the support plate 34. One end of the rotating rod 351 passes through the support plate 34 and is fixed to the output end of the reducer 353. The motor 354 is fixedly connected to the input end of the reducer 353. A mounting plate 341 is fixed on the outer side of the support plate 34. The reducer 353 is fixed on the mounting plate 341, so that the motor 354 drives the rotating rod 351 to rotate through the reducer 353.

[0048] Among them, the elastic component 36 includes a pressure plate 361, a support plate 362, a slide bar 363 and a spring 364. The rear end of the pressure plate 361 is fixed to the scraper 31, the rear end of the support plate 362 is fixed to the support plate 34, the top of the slide bar 363 is fixed on the pressure plate 361, and the outer side of the slide bar 363 slides up and down along the support plate 362, and the upper and lower parts of the spring 364 are respectively fixed to the pressure plate 361 and the support plate 362, so that when the pressure rod 352 rotates downward to press the scraper 31, the pressure plate 361 is driven by force to drive the slide bar 363 to slide downward on the support plate 362, so that the spring 364 is compressed, and after the pressure rod 352 rotates upward, the pressure on the scraper 31 disappears, and the scraper 31 moves upward through the elastic force of the spring 364.

[0049] The scraper 31 is provided with a pressure groove 311 , and the outer side of the pressure rod 352 contacts the bottom of the pressure groove 311 , so that the pressure rod 352 can apply stable pressure to the scraper 31 , which is conducive to the downward movement of the scraper 31 .

[0050] During implementation, a frame plate 365 is provided on the support plate 34, and the left and right ends of the frame plate 365 are fixed to the support plate 34. The rear end of the support plate 362 is fixed on the frame plate 365 so that the support plate 362 can be firmly fixed and placed to meet the sliding support needs of the slide rod 362.
