Description

Technical Field

[0001] This utility model relates to the field of plywood production technology, specifically to a glue applicator for plywood. Background Technology

[0002] Plywood is a sheet material consisting of three or more layers of veneer, made by rotary cutting logs into veneers or slicing timber into thin sheets and then gluing them together with adhesive. It typically uses an odd number of veneer layers, with the grain direction of adjacent veneers glued perpendicular to each other. Adhesive application equipment is required during plywood production.

[0003] In existing technologies, when applying glue to plywood of different heights, glue-applying devices typically use threaded holes of varying heights on the clamping plate to adjust the support plate using threaded rods. This adjustment allows for glue application to plywood of different heights. However, because the vertical threaded holes are spaced apart, the height of the support plate can only be adjusted based on the distance between these holes. This limits the height adjustment, resulting in poor adjustment effectiveness and affecting the versatility of applying glue to plywood of different heights. A glue-applying device for plywood is needed to solve these problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a glue applicator for plywood to solve the problems mentioned in the background art. This utility model has a reasonable structure, good adjustment effect, and high versatility.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a glue-applying device for plywood, comprising:

[0006] The box body has a horizontal electric cylinder installed on the upper side of the inner wall of the box body. The bottom of the slider of the horizontal electric cylinder is equipped with a lifting electric push rod. A U-shaped frame is installed on the telescopic shaft of the lifting electric push rod. A glue-applying roller is rotatably installed inside the U-shaped frame.

Each pair of clamping electric push rods has a clamping plate on its telescopic shaft. Each pair of clamping plates has an adjustment component for adjusting the distance between the top surface of the plywood and the top surface of the clamping plate.

[0008] The adjustment assembly includes two pairs of fixed plates symmetrically arranged on opposite side walls of the clamping plate. A U-shaped adjustment plate is provided on the side of the clamping plate away from the clamping electric push rod. A guide post and a threaded post passing through the U-shaped adjustment plate are arranged sequentially between the fixed plates on the same side wall of the clamping plate. A first gear is provided on the side wall of the threaded post. A drive motor is provided on the fixed plate. A second gear meshing with the first gear is provided on the output shaft of the drive motor.

[0009] Furthermore, a bearing is provided at the connection between the threaded column and the fixed plate, and the U-shaped groove of the U-shaped adjusting plate fits against the side wall of the clamping plate.

[0010] Furthermore, a mounting plate is provided at the bottom of the fixing plate, the drive motor is connected to the mounting plate, and the drive motor and the mounting plate are located between the fixing plates on the same side wall of the clamping plate.

[0011] Furthermore, the upper side of the inner wall of the U-shaped frame is provided with a glue spraying plate located above the glue coating roller, and the bottom of the glue spraying plate is provided with multiple glue spraying nozzles.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following describes this utility model in conjunction with specific embodiments.

[0026] like Figure 1 As shown, this utility model provides a technical solution: a glue applicator for plywood, comprising:

[0027] Box 1, a transverse electric cylinder 2 is provided on the upper side of the inner wall of box 1, a lifting electric push rod 4 is provided at the bottom of the slider of the transverse electric cylinder 2, a U-shaped frame 6 is provided on the telescopic shaft of the lifting electric push rod 4, and a glue applicator 8 is rotatably provided inside the U-shaped frame 6.

[0028] A pair of clamping electric push rods 9 are symmetrically arranged on opposite side walls of the box body 1. Each pair of clamping electric push rods 9 has a clamping plate 92 on its telescopic shaft. Each pair of clamping plates 92 has an adjustment component 10 for adjusting the distance between the top surface of the plywood and the top surface of the clamping plate 92.

[0029] The adjustment assembly 10 includes two pairs of fixed plates 102 symmetrically arranged on opposite side walls of the clamping plate 92. A U-shaped adjustment plate 101 is provided on the side of the clamping plate 92 away from the clamping electric push rod 9. A guide post 103 and a threaded post 105 passing through the U-shaped adjustment plate 101 are arranged sequentially between the fixed plates 102 on the same side wall of the clamping plate 92. A first gear 104 is provided on the side wall of the threaded post 105. A drive motor 107 is provided on the fixed plate 102. A second gear 106 meshing with the first gear 104 is provided on the output shaft of the drive motor 107. This design utilizes a pair of adjustment components 10, where a drive motor 107 drives a second gear 106 to rotate. The rotation of the second gear 106 drives a first gear 104 to rotate, which in turn drives a threaded post 105 to rotate. The rotation of the threaded post 105 causes a U-shaped adjustment plate 101 to slide upwards along the side wall of the clamping plate 92. The upward movement of the U-shaped adjustment plate 101 causes the plywood to move upwards, thus adjusting the height of the plywood and ensuring that the upper surface of the plywood is higher than the upper surface of the clamping plate 92. The rotation of the threaded post 105 also drives the U-shaped support plate 34 to move vertically, adjusting the different heights of the plywood. Compared with the prior art, which uses multiple threaded holes and threaded rods to adjust the height of the plywood, this design offers a wider range of height adjustment capabilities, enhances the adjustment effect, and improves versatility.

[0030] Reference Figure 1 and Figure 2 A bearing is provided at the connection between the threaded column 105 and the fixed plate 102, and the U-shaped groove of the U-shaped adjusting plate 101 fits against the side wall of the clamping plate 92. This design improves the rotational stability of the threaded column 105 through the bearing; the connection between the side wall of the threaded column 105 and the bearing is a smooth surface, which facilitates the connection between the threaded column 105 and the bearing; the fit between the U-shaped groove of the U-shaped adjusting plate 101 and the side wall of the clamping plate 92 ensures the stability of the U-shaped adjusting plate 101 in the vertical direction.

[0031] Reference Figure 2 A mounting plate 1071 is provided at the bottom of the fixed plate 102, and the drive motor 107 is connected to the mounting plate 1071. The drive motor 107 and the mounting plate 1071 are located between the fixed plates 102 on the same side wall of the clamping plate 92. This design facilitates the installation of the drive motor 107 through the mounting plate 1071; wherein, the drive motor 107 and the mounting plate 1071 are located between the fixed plates 102 on the same side wall of the clamping plate 92, avoiding interference between the drive motor 107 and the mounting plate 1071 and the glue application roller 8; the lower end face of the clamping plate 92 is in contact with the lower side of the inner wall of the box 1, improving the stability of the lateral movement of the clamping plate 92.

[0032] Reference Figure 1 , Figure 3 and Figure 4The upper inner wall of the U-shaped frame 6 is equipped with a glue spraying plate 7 located above the glue application roller 8. Multiple glue spray nozzles 71 are located at the bottom of the glue spraying plate 7. A connector 5, connected to an external glue supply source and communicating with the glue spraying plate 7, is located on the side wall of the U-shaped frame 6. This design, through the connection of the external glue supply source to the connector 5, facilitates the entry of glue into the glue spraying plate 7, which then flows out from the nozzles 71 onto the surface of the glue application roller 8, making it convenient to apply glue to the plywood using the glue application roller 8. The external glue supply source can be a glue storage cylinder connected to the connector 5 via a pump, hose, and cable chain, ensuring a continuous supply of glue.

[0033] Reference Figure 4 , Figure 5 and Figure 6 The side wall of the U-shaped frame 6 is equipped with a drying assembly 3 for drying plywood;

[0034] The drying assembly 3 includes a support plate 34 mounted on the side wall of the U-shaped frame 6. An air jet plate 32 is mounted at the bottom of the support plate 34, and multiple air jet nozzles 31 are mounted at the bottom of the air jet plate 32. A hot air blower 33, connected to the air jet plate 32, is mounted at the top of the support plate 34. This design uses the hot air blower 33 in the drying assembly 3 to deliver hot air into the air jet plate 32. The hot air is then blown out from the multiple air jet nozzles 31 onto the plywood, completing the drying operation of the plywood.

[0035] Reference Figure 1 A connecting post 91 is provided between the clamping electric push rod 9 and the clamping plate 92. This design improves the stability of the clamping electric push rod 9 pushing the clamping plate 92 through the connecting post 91.

[0036] Reference Figures 1-6 As an embodiment of this utility model: when it is necessary to adjust the height of the plywood when applying glue, the worker drives the second gear 106 to rotate through the drive motor 107 in the pair of adjustment components 10. The rotation of the second gear 106 drives the first gear 104 to rotate. The rotation of the first gear 104 drives the threaded column 105 to rotate. The rotation of the threaded column 105 drives the U-shaped adjustment plate 101 to slide upward along the side wall of the clamping plate 92. The upward movement of the U-shaped adjustment plate 101 drives the plywood to move upward. This allows for adjustment of different heights of the plywood, with a wider adjustment range, enhanced adjustment effect, improved versatility, and ensures that the upper surface of the plywood is higher than the upper surface of the clamping plate 92.

[0037] When it is necessary to apply glue to the plywood, glue is supplied to the spraying board 7 through an external glue source. The glue flows out from the spray nozzle 71 and falls on the surface of the glue application roller 8. Then, the horizontal electric cylinder 2 works to drive the lifting electric push rod 4 to move laterally to the top of the side of the plywood. Then, the lifting electric push rod 4 works to drive the glue application roller 8 on the U-shaped frame 6 to move downward and stick to the plywood. Similarly, the horizontal electric cylinder 2 works to drive the glue application roller 8 to move laterally to apply glue to the plywood.

[0038] When the plywood after gluing needs to be dried, the horizontal electric cylinder 2 drives the support plate 34 to move laterally. The movement of the support plate 34 drives the hot air blower 33, the air jet plate 32 and the air jet nozzles 31 to move laterally. The hot air blows out hot air through the hot air blower 33 and is sprayed out from multiple air jet nozzles 31 through the air jet plate 32 to dry the plywood with hot air, which improves the practicality of this utility model.
