DETAILED DESCRIPTION

[0032] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The schematic implementation scheme of the present invention and its description are only used to analyze the present invention and are not intended to limit the present invention.

[0034] By arranging a plurality of the glue dispensing rods 6 provided with the glue seepage seams 62, before performing the glue dispensing operation, the screw pump 3 pumps the glue in the glue storage tank 2 into the diverter trough 5, and the glue flows into the trough 61 of the glue dispensing rod 6 through the front glue outlet hole 51 in the diverter trough 5, and flows outward from the glue seepage seams 26 on the side walls of the trough 61, so that the active surface of the glue dispensing rod 6 is covered with glue. After that, the operator only needs to make the toothed end surface of the plate contact with the glue on the active surfaces of the plurality of the glue dispensing rods 6, thereby completing the glue dispensing process on the toothed end surface of the plate at one time.

[0035] Furthermore, if Fig. 9 As shown, a mounting bracket 23 is provided at the bottom of the glue storage tank 2, and the screw pump 3 is installed on the mounting bracket 23. The screw pump 3 includes a driving motor 31, a screw 32, a sealing rod sleeve 33 which is sleeved outside the screw 32 and rotatably connected to the screw 32, and a sealing cylinder 34. One end of the sealing cylinder 34 is sealed and connected to the sealing rod sleeve 33, and the other end is connected to the lower end of the first connecting plate 12. A chamber is provided in the sealing cylinder 34, and the threaded section of the screw 32 is located in the chamber and cooperates with the chamber. A glue outlet 41 is provided on the first connecting plate 12, and the chamber of the sealing cylinder 34 is connected to the ascending channel 4 through the glue outlet hole 41.

[0036] Furthermore, if Figure 6 , Figure 7 As shown, a dust cover 24 is provided on the top of the glue storage tank 2, a feeding port 241 is provided on the dust cover 24, a feeding mask cover 242 is provided above the feeding port 241, mutually matching clamping plates 243 are provided on both sides of the feeding port 241, the clamping plate 243 is tilted upward toward one side of the feeding port 241 to form a supporting portion 244, the feeding mask cover 242 is located between the two clamping plates 243, the edges on both sides of the feeding mask cover 242 extend downward and bend to form an L-shaped flange 245, the L-shaped flange 245 and the inner side of the supporting portion 244 are abutted against each other, and the feeding mask cover 242 can slide relative to the clamping plate 243;

[0037] like Figure 6 , Figure 8As shown, the bottom surface of the glue storage tank 2 is provided with a glue outlet groove 21 arranged in the longitudinal direction, and the top of the glue storage tank 2 is also provided with a mounting plate 25, and a second adjusting bolt 26 is provided on the mounting plate 25. The bottom of the second adjusting bolt 26 is conical, and the second adjusting bolt 26 passes downward through the mounting plate 25 and cooperates with the top edge of the glue outlet groove 21. The second adjusting bolt 26 adjusts the distance between the second adjusting bolt 26 and the top edge of the glue outlet groove 21 by moving up and down, thereby adjusting the flow rate of the glue when it flows into the screw pump 3. The glue storage tank 2 is connected with the interior of the chamber of the sealing cylinder 34 through the glue outlet groove 21; the inner side wall of the glue storage tank 2 is provided with a glue collecting groove 22 arranged in the transverse direction, and the second connecting plate 13 is provided with a collecting channel 9, and the collecting channel 9 is provided with a through hole, and is connected with the glue collecting groove 22 through the through hole.

[0038] Furthermore, if Figure 8 As shown, a rectifying plate 27 is further provided in the glue storage tank 2, and the upper side of the rectifying plate 27 is fixedly connected to the mounting plate 25. A plurality of U-shaped openings are evenly distributed on the rectifying plate 27, and the rectifying plate 27 is used to keep the flow rate of the glue near the glue outlet trough 21 uniform.

[0039] Furthermore, if Figure 3 , Fig.10 As shown, a flange 63 is provided on the upper edge of the glue dispensing stick 6, and a sealing ring 56 is provided between the flange 63 and the front glue outlet hole 51. A slot cover 52 is provided on the top of the diverter slot 5, and a tightening screw 53 is provided on the slot cover 52. The bottom end of the tightening screw 53 extends into and presses against the bottom of the sinking slot 61 of the glue dispensing stick 6; the bottom end of the tightening screw 53 presses against the bottom of the sinking slot 61. When the tightening screw 53 is moved downward by rotating or pressing down, the tightening screw 53 pushes the glue dispensing stick 6 to move downward, and the flange 63 presses the sealing ring 56 downward as the glue dispensing stick 6 moves downward, so that the sealing ring 56 rubs with the front glue outlet hole 51 and the flange 63 to form a sealed connection, thereby preventing the glue from leaking out from the gap between the front glue outlet hole 51 and the glue dispensing stick 6.

[0040] Furthermore, if Figure 2 , Figure 3 As shown, the glue seepage seam 62 is opened in the transverse direction, and the opening size of the glue seepage seam 62 is adapted to the curvature of the wave valley of the plate. The glue liquid seeps downward through the transversely arranged glue seepage seam 62, so that the active surface of the glue dispensing rod 6 is covered with glue liquid.

[0041] Furthermore, although, when the action surface of the dispensing stick 6 contacts and abuts against the trough of the toothed end face of the plate, the two may work together to squeeze a portion of the glue liquid out of the trough, the toothed end face of the plate has not only troughs but also crests, and the crests are in front of the troughs. If the distance between the two troughs on the toothed end face is large, that is, the size of the crests is large, the portion of the glue liquid squeezed out may not be able to completely overflow to the crest of the toothed end face. In order to overcome this defect and ensure that the dispensing process can be completed in one go, such as Figure 2 , Fig.10 As shown, in the present embodiment, a rear glue outlet hole 54 is further provided in the diverter groove 5, and a glue dispensing groove body 7 is further connected to the bottom of the diverter groove 5. A glue coating groove 71 with an opening toward the glue dispensing rod 6 is provided on the glue dispensing groove body 7 in the longitudinal direction, and the size of the glue coating groove 71 is adapted to the crest curvature of the toothed end face of the plate, and a drainage channel 72 connected to the rear glue outlet hole 54 is further provided on the upper part of the glue dispensing groove body 7; while the glue dispensing rod 6 is used to perform glue dispensing on the trough of the toothed end face of the plate, the glue coating groove 71 is used to perform glue dispensing on the crest of the toothed end face of the plate, and the glue dispensing rod 6 cooperates with the glue coating groove 71 so that the toothed end face of the plate is fully covered with glue, thereby completing the glue dispensing operation at one time.

[0042] Furthermore, if Fig.10 As shown, a first adjusting bolt 55 is also provided on the slot cover 52 at the top of the diverter slot 5. The bottom of the first adjusting bolt 55 is conical and cooperates with the rear glue outlet hole 54. The first adjusting bolt 55 adjusts the distance between the first adjusting bolt 55 and the rear glue outlet hole 54 by moving up and down, thereby adjusting the flow rate of the glue when it flows into the rear glue outlet hole.

[0043] Furthermore, in this embodiment, if Fig.11 As shown, the drainage channel 72 is actually a glue storage trough arranged on the upper surface of the glue dispensing tank body 7, and the bottom of the rear glue outlet hole 54 is distributed within the opening range of the glue storage trough. The upper surface of the glue dispensing tank body 7 is also provided with a transition groove 73 formed by a downward depression, and there are two transition grooves 73 and two glue coating grooves 71, wherein an overflow port is opened on the side wall of the glue storage trough, and is connected with the transition groove 73 through the overflow port, and the transition groove 73 is connected with the glue coating groove 71, and the outer edge of the bottom of the transition groove 73 is completely connected with the upper edge of the glue coating groove 71.

[0044] Furthermore, in order to ensure the cleanliness of the interior of the device and avoid glue waste, Figure 1 , Fig.12 , Fig.13As shown, in the present embodiment, a collecting groove 8 is further provided below the diverter groove 5, and an opening is provided at the top of the collecting groove 8, and the bottoms of the glue coating groove 71 and the glue dispensing rod 6 are both distributed within the opening range of the collecting groove 8, and the inner bottom surface of the collecting groove 8 is inclined downward to one side, and a glue leakage hole 81 is provided at a low position of the inner bottom surface, and the glue leakage hole 81 is connected to the collecting channel 9, and is connected to the glue storage tank 2 through the collecting channel 9; the glue liquid on the glue dispensing rod 6 and the glue coating groove 71 that fails to adhere to the toothed end surface of the plate material drips from the glue dispensing rod 6 and the glue coating groove 71 into the collecting groove 8 under the action of its own weight, and under the action of the inner bottom surface of the collecting groove 8, flows and accumulates to a low position in the collecting groove 8, and then flows into the collecting channel 9 through the glue leakage hole 81 at a low position, and flows back to the glue storage tank 2 through the collecting channel 9.

In other embodiments, the dust cover 8 is actually provided with a through hole corresponding to the glue coating tank 7.

[0046] Furthermore, if Figure 1 As shown, the screw pump 3, the rising channel 4 and the collecting channel 9, the diversion trough 5 and the collecting trough 8 are each provided with two sets, and correspondingly, the inner bottom surface of the glue storage tank 2 is provided with two glue outlet grooves 21 corresponding to the two screw pumps 3, and the inner side wall of the glue storage tank 2 is provided with two glue receiving grooves 22 corresponding to the two collecting channels 9.
