A seamless edge banding device for paint-free wooden door products

Abstract

This invention discloses a seamless edge-sealing device for paint-free wooden doors, relating to the field of wood processing. It solves the problems of instability during door movement and ineffective heat treatment of the paint-free board. The device includes a tabletop with a fixed shelf on its top. The shelf contains several vertically arranged, linearly equidistant rollers. The invention allows for flexible adjustment of the position of the heat-treatment components via an adjustment mechanism, ensuring effective contact between the side of the Teflon high-temperature resistant cloth and the paint-free board. After adjustment, the heat-treatment components can be directly positioned via a touch component.

During displacement, a pressure component intermittently and frequently applies pressure to the side of the wooden door, ensuring the hot-melt adhesive film between the paint-free board and the door is fully heated and fluidized, guaranteeing the stability of the bond.

Description

Technical Field

[0001] This invention relates to the field of wood processing, specifically to a seamless edge banding device for paint-free wooden door products. Background Technology

[0002] Paint-free wooden doors are wooden doors that do not require spraying, brushing, or baking paint treatment. The paint-free board can be directly pasted onto the surface of the wooden door material using hot melt adhesive film as a binder to achieve the effect of a painted wooden door. When processing paint-free wooden doors without edge banding, an edge banding device is required.

[0003] Existing Chinese patent document CN214026176U discloses a seamless edge banding device for wooden door processing. This device comprises a support plate, mounting frame, electric telescopic rod, connecting sleeve, support column, movable support column, first screw hole, limiting screw, and support column. When edge banding a wooden door, the height of the support plate can be adjusted according to the thickness of the wooden door to align the edge banding machine's sealing edge with the edge of the wooden door. Through a slider, wooden door placement plate, connecting rod, ball screw, mounting plate, support rod, slide rail, and ball nut, the wooden door placement plate can easily move the wooden door on the support plate, allowing the edge banding machine to continuously seal the wooden door, thus improving the practicality of the seamless edge banding device.

[0004] In existing technologies, the edge banding device only addresses how to align the wooden door with the edge banding machine's edge. It does not consider that after the wooden door and the edge banding are horizontally aligned, it is also necessary to ensure that the edge banding can effectively contact the side of the wooden door during movement and to perform heat treatment on the paint-free board attached to the side of the wooden door. In other words, existing seamless edge banding devices cannot guarantee the stability of the wooden door during movement or the effective heat treatment of the paint-free board, thus failing to guarantee the quality of the paint-free wooden door. Additional clamping or positioning components are required to temporarily fix the wooden door to the upper part of the wooden door placement board. Therefore, we propose a seamless edge banding device for paint-free wooden door products. Summary of the Invention

[0005] The purpose of this invention is to provide a seamless edge banding device for paint-free wooden door products that is highly flexible and can ensure effective heat treatment bonding between wooden door panels and paint-free boards, thereby solving the problems mentioned in the background art.

Two heating resistance rods for heating the heat-conducting block are fixedly installed inside the heat-conducting block, and both the upper and lower ends of the heating resistance rods are fixedly inserted through the fixed frame. The tops of the two heating resistance rods are provided with power sockets through electrical wires. When the power sockets are powered on, the heating resistance rods can heat up and transfer heat energy to the heat-conducting block.

[0008] Preferably, the driving assembly includes a rotating shaft that is rotatably embedded inside the fixed frame, and the rotating shaft is distributed on the side of the heat-conducting block away from the placement frame. A slide cylinder is fixedly sleeved on the outer surface of the rotating shaft, and gears are fixedly installed at both the upper and lower ends of the slide cylinder.

Toothed belts are fixedly installed at both the upper and lower ends of the inner side of the Teflon high-temperature resistant cloth, and the toothed belts are movably meshed with gears. A silicone layer is adhered to the outer surface of the Teflon high-temperature resistant cloth. The function of the silicone layer is to increase the friction when the Teflon high-temperature resistant cloth contacts the paint-free board.

In conjunction with the cooperation between the slider and the straight groove rail, the heat treatment component can be flexibly adjusted axially and laterally. A bracket is fixedly installed on the upper part of the lifting shaft, and a pressure application component is provided between the bracket and the fixed frame.

[0010] Preferably, the pressure-applying component includes a connecting rod fixedly installed inside the bracket, and the connecting rod is perpendicular to the straight groove rail.

A synchronous belt is installed between the gear two and the gear three. Sliding sleeve blocks are slidably fitted onto both ends of the bracket, and a spring two is fixedly installed between the end of the bracket near the motor and the sliding sleeve block. The sliding sleeve block is fixedly located at the bottom of the fixed frame. The stiffness of the spring one is greater than twice the stiffness of the spring two, that is, the reaction force generated by the pushing of the spring one can overcome the elastic force of the two spring twos and compress them.

[0011] Preferably, the locking assembly includes a limiting frame fixedly sleeved on the top of the sleeve, a friction groove on the outer surface of the lifting shaft, two circumferentially equidistant sliding blocks slidably embedded inside the limiting frame, two spring pieces fixedly installed between the two sliding blocks, and rubber pads fixedly installed at the ends of the two spring pieces near the axis of the sleeve. When the two sliding blocks slide relative to each other, they can pull the two spring pieces, causing the two rubber pads to contact the lifting shaft. A spring is fixedly installed between the end of the sliding block away from the spring piece and the limiting frame, and a push arm is hingedly installed at the end of the sliding block away from the placement frame. The other ends of the two push arms are hingedly installed with a hinged seat block, and an actuating component is provided on the outer side of the hinged seat block.

[0012] Preferably, the actuating component includes a base plate fixedly installed on the outer surface of the sleeve, and the base plate is distributed at the bottom of the limiting frame. A fitting block is slidably embedded inside the base plate, and a connecting rod is fixedly installed between the fitting block and the hinge block. A cam is fitted to the end of the hinge block away from the limiting frame, and a rotating handle is fixedly embedded inside the cam. The bottom of the rotating handle is rotatably embedded inside the base plate. When the rotating handle rotates with the cam, it can push the hinge block. A limiting component is provided on the outer side of the fitting block.

[0013] Preferably, the limiting component includes a toothed plate that is vertically placed and slidably embedded inside the base plate, and a toothed block that meshes with the toothed plate is fixedly installed at one end of the interlocking block near the toothed plate. A U-shaped slide rod that slides through the base plate is fixedly installed at the other end of the toothed plate away from the interlocking block, and a tension spring is fixedly provided between the end face of the base plate away from the interlocking block and the U-shaped slide rod. Through the action of the tension spring, the stable meshing of the interlocking block and the toothed plate can be ensured, and the retraction of the hinged seat block can be avoided.

[0014] Preferably, the braking assembly includes L-shaped plates symmetrically distributed and slidably embedded inside the slider, with a rubber block fixedly installed at the lower end of the L-shaped plates and slidingly penetrating the slider. A conical bottom push block is slidably provided between the two L-shaped plates, and a rounded corner abutment is fixedly installed at the top of the conical bottom push block via a column. A spring is fixedly installed between the end of the L-shaped plate away from the conical bottom push block and the slider. A pushing block is fixedly installed at the bottom of the fitting block, and the inclined surface of the pushing block fits against the arc surface of the rounded corner abutment. When the fitting block slides, it can push the rounded corner abutment through the pushing block, causing the conical bottom push block to slide downward.

[0015] The beneficial effects of this invention compared with the prior art are as follows: This invention can flexibly adjust the position of the heat treatment component through the adjustment component, so that the side of the Teflon high-temperature resistant cloth can be effectively attached to the paint-free board. After the position adjustment is completed, the position of the heat treatment component can be directly positioned by the touch component. Through the action of the drive component, during the heat treatment process of the paint-free board, the wooden door can be moved directly by the transmission of the Teflon high-temperature resistant cloth in conjunction with the roller. During the displacement, the pressure component can intermittently and frequently apply pressure to the side of the wooden door, ensuring that the hot melt adhesive film between the paint-free board and the wooden door is fully heated and becomes fluid, and squeezing out the air between the two, ensuring the stability of the adhesion between the two.

When the power socket 19 is powered on, it can make the heating resistance rods 18 heat up and transfer the heat energy to the heat-conducting block 17.

[0030] Please see Figure 3 and Figure 4 The driving component 10 shown in the figure includes a rotating shaft 20 that is rotatably embedded inside the fixed frame 16.

A motor 33 is fixedly installed at the bottom of the fixed frame 16, and the output end of the motor 33 is fixedly connected to the rotating shaft 20.

[0031] Please see Figure 3 , Figure 6 and Figure 7 The adjustment component 5 shown in the figure includes a straight groove rail 11 fixedly installed on the upper end of the table panel 1, and a slider 12 is slidably embedded in the inner side of the straight groove rail 11. A sleeve 13 is fixedly installed on the top of the slider 12, and a lifting shaft 14 is axially slidably embedded inside the sleeve 13. That is, the lifting shaft 14 can drive its upper structure to slide axially. In conjunction with the cooperation between the slider 12 and the straight groove rail 11, the heat treatment component 4 can be flexibly adjusted axially and laterally. A bracket 15 is fixedly installed on the upper part of the lifting shaft 14, and a pressure application component is provided between the bracket 15 and the fixed frame 16.

[0032] Please see Figure 7The locking assembly 6 shown in the figure includes a limiting frame 34 fixedly sleeved on the top of the sleeve 13. The outer surface of the lifting shaft 14 is provided with a friction groove. Two sliding blocks 38 are equidistantly distributed in a circle inside the limiting frame 34. Two spring pieces 40 are fixedly installed between the two sliding blocks 38. A rubber pad 41 is fixedly installed at one end of the two spring pieces 40 near the axis of the sleeve 13. When the two sliding blocks 38 slide relative to each other, they can pull the two spring pieces 40, so that the two rubber pads 41 contact the lifting shaft 14. A spring 39 is fixedly installed between the end of the sliding block 38 away from the spring piece 40 and the limiting frame 34. A push arm 42 is hingedly installed at the end of the sliding block 38 away from the placement frame 2. The other ends of the two push arms 42 are hingedly installed with a hinge block 43. An actuating assembly 7 is provided on the outside of the hinge block 43.

[0033] Please see Figure 8 and Figure 9 The trigger component 7 shown in the figure includes a base plate 35 fixedly installed on the outer surface of the sleeve 13, and the base plate 35 is distributed at the bottom of the limiting frame 34. A fitting block 45 is slidably embedded inside the base plate 35, and a connecting rod 44 is fixedly installed between the fitting block 45 and the hinge block 43. A cam 37 is fitted to the end of the hinge block 43 away from the limiting frame 34, and a rotating handle 36 is fixedly embedded inside the cam 37. The bottom of the rotating handle 36 is rotatably embedded inside the base plate 35. When the rotating handle 36 rotates with the cam 37, it can push the hinge block 43. A limiting component 9 is provided on the outer side of the fitting block 45.

[0034] Please see Figure 10 The braking assembly 8 shown in the figure includes L-shaped plates 54 symmetrically distributed and slidably embedded inside the slider 12. A rubber block 55 that slides through the slider 12 is fixedly installed at the lower end of the L-shaped plates 54. A conical bottom pusher 53 is slidably provided between the two L-shaped plates 54. A rounded corner abutment 51 is fixedly installed at the top of the conical bottom pusher 53 through the column 52. A spring 56 is fixedly installed between the end of the L-shaped plate 54 away from the conical bottom pusher 53 and the slider 12. A pushing block 50 is fixedly installed at the bottom of the fitting block 45. The inclined surface of the pushing block 50 fits against the arc surface of the rounded corner abutment 51. When the fitting block 45 slides, it can push the rounded corner abutment 51 through the pushing block 50, causing the conical bottom pusher 53 to slide downward.

[0035] The working principle of this highly flexible system, which ensures effective heat treatment bonding between the wooden door and the paint-free board, is as follows: After the worker attaches the paint-free board to the side of the wooden door using hot melt adhesive film, the wooden door is placed on top of the placement rack 2. At this point, the position of the fixing frame 16 can be adjusted by the thickness and width of the wooden door. During the adjustment process, the horizontal and axial positions of the fixing frame 16 can be flexibly adjusted through the engagement of the slider 12 and the straight track 11, and the engagement of the lifting shaft 14 and the sleeve 13, ensuring the high-temperature resistant Teflon coating. When the cloth 22 is attached to the left end face of the wooden door, the cam 37 can be rotated by the handle 36. During the process of the cam 37 pushing the hinge block 43, its push arm 42 can make the two sliding blocks 38 unfold relative to each other. During the unfolding process, the two spring pieces 40 are pulled, so that the two spring pieces 40 gradually flatten. During the flattening process, the rubber pad 41 can be attached to the outer surface of the lifting shaft 14. Under the continuous pressure of the cam 37, the rubber pad 41 can be squeezed and deformed, so that the spring piece 40 can effectively lock and restrict the lifting shaft 14.

[0036] During the sliding process of the interlocking block 45, its pushing block 50 can push the rounded corner abutment block 51, causing the rounded corner abutment block 51 to move downward. At this time, the conical bottom pushing block 53 can push the two L-shaped plates 54, causing the rubber block 55 to press against the inner wall of the straight groove rail 11. Through the friction between the rubber block 55 and the straight groove rail 11, the lateral restriction of the fixed frame 16 can be guaranteed.

[0037] After the wooden door is positioned, the power socket 19 is powered on, which heats the heating resistance rod 18 and transfers the heat to the heat-conducting block 17. The heat-conducting block 17 then heats the paint-free board through the Teflon high-temperature resistant cloth 22, causing the hot melt adhesive film between the paint-free board and the wooden door to become fluid and fully and evenly distributed between them, thus ensuring effective adhesion between the paint-free board and the wooden door. Example

[0038] Please see Figure 8 and Figure 9 This embodiment further explains Example 1. The limiting component 9 includes a toothed plate 47 that is vertically placed and slidably embedded inside the base plate 35. A toothed block 46 that meshes with the toothed plate 47 is fixedly installed at one end of the fitting block 45 near the toothed plate 47. A U-shaped slide rod 48 that slides through the base plate 35 is fixedly installed at one end of the toothed plate 47 away from the fitting block 45. A tension spring 49 is fixedly provided between the end face of the base plate 35 away from the fitting block 45 and the U-shaped slide rod 48.

[0039] In this embodiment, the tension spring 49 ensures the stable engagement of the locking block 45 and the toothed plate 47, preventing the hinge block 43 from retracting. This ensures the stability of the locking assembly 6 and the braking assembly 8. When adjustments are needed later, simply pull the U-shaped slide bar 48 outwards, and the locking block 45 will retract. Example

[0040] Please see Figure 5 This embodiment further illustrates other embodiments, the pressure-applying component includes a connecting rod 24 fixedly installed inside the bracket 15, and the connecting rod 24 is perpendicular to the straight groove rail 11. A sleeve frame 25 is slidably sleeved on the outer surface of the connecting rod 24, and a spring 26 is fixedly installed between the end of the connecting rod 24 near the placement frame 2 and the sleeve frame 25. An elliptical wheel 32 is slidably fitted on the side of the sleeve frame 25 away from the motor 33, and the elliptical wheel 32 is rotatably mounted on the lower end of the fixed frame 16 through an internally fixed rotating column. A spring 26 is fixedly sleeved on the outer surface of the rotating column. Gear 30 and Gear 29 are fixedly sleeved at the output end of motor 33, and a synchronous belt 31 is installed between gear 29 and gear 30 for transmission. Sliding sleeve blocks 27 are slidably sleeved at both ends of bracket 15, and spring 28 is fixedly installed between the end of bracket 15 near motor 33 and sliding sleeve block 27. Sliding sleeve block 27 is fixedly set at the bottom of fixed frame 16. The stiffness of spring 1 26 is greater than twice the stiffness of spring 2 28, that is, the reaction force generated by spring 1 26 being pushed can overcome the elastic force of two springs 2 28 and compress them.

[0041] In this embodiment: when the wooden door is heat-treated by the Teflon high-temperature resistant cloth 22 and the roller 3, the start of the motor 33 can drive the elliptical wheel 32 to rotate through the action of gear 29, gear 30 and synchronous belt 31. During the rotation, the elliptical wheel 32 can frequently push against the frame 25, compressing the spring 26. The reaction force generated by the compression of the spring 26 can form a pushing force on the elliptical wheel 32, making the entire fixed frame 16 and its internal structure tend to move towards the placement rack 2. At the same time, the reaction force can overcome the elasticity of the two springs 28, increasing the pressure applied to the paint-free board by the heat-conducting block 17 through the Teflon high-temperature resistant cloth 22. After the hot melt adhesive film melts, the air between the paint-free board and the wooden door can be squeezed out by intermittently applying pressure to the paint-free board, so that the hot melt adhesive can be more fully filled between the two. After the hot melt adhesive cools down, the stability between the paint-free board and the wooden door can be guaranteed.

[0042] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the protection scope of this invention.
