Description

Technical Field

[0001] This utility model belongs to the field of plywood production technology, specifically a plywood gluing equipment. Background Technology

[0002] Plywood is a commonly used material in furniture making and one of the three major types of engineered wood products. Plywood is typically made by rotary cutting logs into veneers or slicing timber into thin sheets, then gluing multiple layers of these sheets together. During plywood production, gluing equipment is used to evenly apply glue to the plywood. Depending on the application requirements, different sizes of plywood need to be processed. However, existing gluing equipment is not convenient for adjusting the glue coverage according to the material's dimensions, easily leading to excess glue waste.

[0003] Chinese utility model patent CN222553824U discloses an environmentally friendly plywood gluing device. This device adapts the size of the gluing drum to the size of the plywood to be glued by changing the drum's dimensions. However, the device lacks a glue storage tank, preventing automatic gluing of drums of different sizes. In actual production, operators must frequently replenish the glue manually, consuming significant manpower and severely limiting gluing efficiency, making it difficult to meet the high-efficiency requirements of modern large-scale industrial production.

Detailed Implementation

[0028] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0030] See Figure 1 , Figure 2 , Figure 4 and Figure 6 This embodiment provides a plywood gluing device, including a glue tank 1, an adjusting plate 3, and a sealing plate 4. A glue outlet groove 2 is provided on the bottom wall of the glue tank 1. Two sets of adjusting plates 3 and two sets of sealing plates 4 are slidably arranged within the glue tank 1. The two sets of sealing plates 4 are symmetrically arranged on both sides of the adjusting plate 3, and the sealing plates 4 are perpendicular to the adjusting plate 3. A glue storage space is formed between the two sets of sealing plates 4 and the two sets of adjusting plates 3. The part connecting the glue outlet groove 2 and the glue storage space is a glue outlet channel. By sliding the two sets of adjusting plates 3 within the glue tank 1, the dimensions of the glue storage space and the glue outlet channel are adjusted so that the dimensions of the glue outlet channel are adapted to the dimensions of the plywood to be glued, avoiding glue waste. Furthermore, the positional movement of the sealing plates 4 ensures the sealing degree between the adjusting plate 3 and the sealing plates 4.

[0031] This embodiment also provides a plywood gluing device, which further includes a detachable glue dispensing roller 5 and a glue coating roller 6. The glue dispensing roller 5 and the glue coating roller 6 are configured to be raised and lowered relative to the glue dispensing groove 2. In the raised state, the glue dispensing roller 5 is rotatably disposed in the glue dispensing groove 2. The size of the glue dispensing roller 5 and the glue coating roller 6 is adapted to the size of the glue dispensing channel. The glue coating roller 6 is located below the glue dispensing roller 5 and is in rotatable contact with the glue dispensing roller 5.

[0032] During operation, initially, the sealing plate 4 does not contact the side wall of the adjusting plate 3. The dimensions of the glue storage space and the glue dispensing channel are adjusted according to the width of the plywood to be glued. The two sets of adjusting plates 3 are driven to slide within the glue tank 1. When the distance between the two sets of adjusting plates 3 (i.e., the size of the glue dispensing channel) matches the size of the plywood, the adjustment plates 3 are stopped. The two sets of sealing plates 4 are driven to approach the two sets of adjusting plates 3 from both sides, forming a well-sealed glue storage space. Then, glue dispensing roller 5 and glue coating roller 6, matching the size of the glue dispensing channel, are installed, and their lifting and lowering are adjusted. Glue dispensing roller 5 rotates within the glue dispensing groove 2. Glue is added to the storage space, and the glue dispensing roller 5 and glue coating roller 6 are started to rotate. The rotating glue dispensing roller 5 carries the glue out from the glue dispensing channel and transfers it to the rotating glue coating roller 6. The rotating glue coating roller 6 then applies glue to the plywood conveyed below it.

[0033] Specifically, see Figure 6 and Figure 7 In this embodiment, a plywood gluing device further includes a lifting mechanism. The lifting mechanism is used to drive the glue dispensing roller 5 and the glue coating roller 6 to lift. The lifting mechanism includes a mounting plate 7, a lifting motor 8, a lifting screw 9, a lifting slide bar 10, and a lifting plate 11. The mounting plate 7 is fixedly installed below the glue box 1. A lifting groove 12 is provided on the mounting plate 7. The lifting motor 8 is fixedly installed inside the mounting plate 7. The lifting screw 9 is rotatably installed inside the lifting groove 12. One end of the lifting screw 9 is connected to the output end of the lifting motor 8. The lifting slide bar 10 is fixedly installed inside the lifting groove 12. The lifting plate 11 is connected to the lifting screw 9 by a thread. The lifting plate 11 is slidably installed on the lifting slide bar 10.

[0034] During operation, the lifting motor 8 is started, which drives the lifting screw 9 to rotate. Driven by the lifting screw 9 and guided by the lifting slide 10, the lifting plate 11 is raised and lowered. The lifting plate 11 then raises and lowers the dispensing roller 5 and the coating roller 6. By controlling the dispensing roller 5 and the coating roller 6 to descend away from the dispensing trough 2, it is convenient to replace the dispensing roller 5 and the coating roller 6. When the dispensing roller 5 and the coating roller 6 are raised, the dispensing roller 5 can be moved into the dispensing trough 2 and rotated in the dispensing channel, thereby carrying out the glue in the glue box 1.

[0035] Specifically, see Figure 1 , Figure 2 and Figure 5 In this embodiment, two sets of lifting mechanisms are symmetrically arranged on both sides of the glue box 1, and the two sets of lifting plates 11 are raised and lowered synchronously. A first position adjustment mechanism 13 is provided on the lifting plate 11, and a drive plate 14 is provided on the first position adjustment mechanism 13. Two sets of drive shafts 15 are rotatably provided on the drive plate 14. The glue dispensing roller 5 and the glue coating roller 6 are detachably connected to a set of drive shafts 15 respectively. A rotation drive mechanism is provided in the drive plate 14 on a set of lifting plates 11, and the rotation drive mechanism is connected to the drive shaft 15 on its corresponding drive plate 14.

[0036] Specifically, see Figure 6 In this embodiment, the rotation drive mechanism includes a rotation motor 16 and a transmission shaft 17. The rotation motor 16 is located inside the drive plate 14. A set of drive shafts 15 is connected to the output end of the rotation motor 16. The transmission shaft 17 is rotatably located inside the drive plate 14. Belt pulleys are fixedly provided on the rotation motor 16 and the transmission shaft 17. Drive belts 18 are sleeved on the two sets of belt pulleys. A set of gears 19 is fixedly provided on both the transmission shaft 17 and the other set of drive shafts 15. The two sets of gears 19 mesh.

[0037] During operation, the rotating motor 16 drives a set of drive shafts 15 to rotate. Through the drive belt 18, the set of drive shafts 15 drives the transmission shaft 17 to rotate. Through the meshing transmission of two sets of gears 19, the transmission shaft 17 drives another set of drive shafts 15 to rotate. The two rotating drive shafts 15 respectively drive the glue roller 5 and the glue coating roller 6 to rotate.

[0038] Specifically, see Figure 2 , Figure 3 and Figure 7 In this embodiment, the two ends of the dispensing roller 5 and the coating roller 6 are respectively provided with connecting shafts 20. One of the connecting shafts 20 and the drive shaft 15 is provided with a mounting protrusion 21, and the other is provided with a mounting groove 22. The mounting protrusion 21 and the mounting groove 22 are adapted to each other.

[0039] During operation, firstly, a set of first position adjustment mechanisms 13 is activated to move, causing the corresponding drive plate 14 to move to the position corresponding to the sliding adjustment plate 3. The connecting shaft 20 at one end of the dispensing roller 5 and the coating roller 6 is then fitted into the drive shaft 15 on the drive plate 14 through the cooperation of the mounting protrusion 21 and the mounting groove 22. Then, another set of first position adjustment mechanisms 13 is activated, which drives the drive plate 14 to move and connects the drive shaft 15 on it to the connecting shaft 20 at the other end of the dispensing roller 5 and the coating roller 6, thus completing the installation of the dispensing roller 5 and the coating roller 6.

[0040] Specifically, see Figure 1 , Figure 2 and Figure 4 In this embodiment, the side wall of the glue box 1 is provided with a second position adjustment mechanism 23, and the adjustment plate 3 and the sealing plate 4 are both connected to a set of second position adjustment mechanisms 23.

[0041] It is understood that in this embodiment, the purpose of the first position adjustment mechanism 13 and the second position adjustment mechanism 23 is to adjust the position of the connected structural components. Therefore, the first position adjustment mechanism 13 and the second position adjustment mechanism 23 can be selected as a cylinder mechanism or a screw adjustment mechanism. As a preferred implementation, in order to improve the sealing tightness between the sealing plate 4 and the adjustment plate 3, the second position adjustment mechanism 23 connected to the sealing plate 4 is selected as a cylinder mechanism.
