Abstract

The present invention discloses a hot bending device for arc edge banding strips with waste recycling, belonging to the technical field of hot bending of edge banding strips. It includes a main frame device which is used to break the edge banding strips that are unqualified in hot bending. A hot folding device and a bending device are arranged on the main frame device, and the hot folding device and the bending device cooperate to perform hot bending on the edge banding strips. Two clamping mechanisms clamp both ends of the edge banding strip to facilitate the hot bending of the edge banding strip. When the edge banding is completed, the clamping mechanisms can automatically open, enabling the hot-bent edge banding strip to fall into the dropping groove, realizing automatic discharging. The inner pressing block first performs the first-step hot pressing on the edge banding strip, and then the outer pressing block, the secondary outer pressing block, and the secondary inner pressing block perform sequential hot pressing on the edge banding strip.

The camera detects the hot-bent edge banding strip. For the unqualified edge banding strips, they are put into the crushing mechanism through the switching frame for crushing, realizing waste recycling.

Description

Technical Field

[0001] The present invention relates to the technical field of edge banding heat bending, and particularly to an arc edge banding heat bending device with waste recycling. Background Art

[0002] Edge banding is a material commonly used in woodworking and furniture manufacturing, mainly used to cover and decorate the cut edges of wood, boards or other materials. The function of edge banding is not only for aesthetics, but also to improve the durability, moisture resistance and wear resistance of the board, preventing moisture, dust and bacteria from invading the edges of the wood. Edge banding is widely used in the production of furniture, cabinets, floors, doors and windows and other products. Edge banding heat bending refers to the process of heating the edge banding material to make it soft and then performing bending processing. This process is commonly used in furniture manufacturing and the woodworking industry, especially when installing edge banding on the edges of wooden boards to ensure the aesthetics and durability of the edges. The heat bending process usually requires controlling the temperature and bending angle to ensure that the edge banding is not damaged and can be accurately fitted to the edge of the wooden board. The edge banding heat bending devices in the prior art usually only perform heat bending on the two ends of the edge banding and cannot perform multi-level heat bending on the edge banding. Compared with single heat bending, step-by-step multi-heat bending can improve the heat bending quality and reduce internal stress at the same time. At the same time, the edge banding with poor heat bending quality needs to be recycled. Summary of the Invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: an arc edge banding heat bending device with waste recycling, including a main frame device. The main frame device includes a bottom frame. The main frame device is used to crush the edge banding with unqualified heat bending. A heat folding device and a bending device are arranged on the main frame device. The heat folding device includes a bending arc plate. The bending device includes an upper sliding plate. The heat folding device and the bending device cooperate to perform heat bending on the edge banding.

[0004] The main frame device includes an upper track plate fixedly installed on the bottom frame. The bending arc plate is fixedly installed on the upper track plate. The upper sliding plate is fixedly installed on the upper track plate. A crushing mechanism is arranged on the bottom frame.

[0005] The heat folding device includes two inner rotating rods rotatably installed at the lower part of the upper track plate. Side frames are fixedly installed on both sides of the upper track plate. Sliders are slidably installed in the side frames. Sliding rods are slidably installed in the sliders. The sliding rods are rotatably installed with the inner rotating rods.

[0006] The bending device includes two outer pressing blocks, two secondary outer pressing blocks, two secondary inner pressing blocks and an inner pressing block slidably installed on the upper sliding plate.

[0007] Further, the main frame device further includes a switching box slidably mounted on the bottom frame. The switching box is divided into two cavities, a finished product cavity and a waste product cavity. A switching electric cylinder is fixedly mounted on the bottom frame. A side slider is fixedly mounted on the side of the switching box. The side slider is fixedly mounted on the output end of the switching electric cylinder. A side guide rail is fixedly mounted on the bottom frame. The side slider is slidably mounted on the side guide rail. An unloading slope is fixedly mounted on the bottom frame.

[0008] Further, the crushing mechanism includes a crushing box fixedly mounted on the bottom frame. Two crushing rollers are rotatably mounted on the crushing box. A crushing motor is fixedly mounted on the crushing box. The motor shaft of the crushing motor is fixedly mounted on one of the crushing rollers. Crushing gears are fixedly mounted on both crushing rollers. The two crushing gears mesh with each other.

[0009] The telescopic movement of the switching electric cylinder can drive the switching box and the side slider to slide along the side guide rail. When the camera detects that the edge banding is qualified after hot bending, the switching electric cylinder does not move, and the edge banding after hot bending falls into the finished product cavity and onto the bottom frame. Subsequently, the switching electric cylinder contracts, and the edge banding is brought to the unloading slope through the switching box, and the edge banding leaves through the unloading slope. If the camera detects that the edge banding is unqualified after hot bending, the switching electric cylinder first contracts, and then the edge banding falls into the waste product cavity. Subsequently, the switching electric cylinder extends, and the edge banding is pushed into the crushing box through the switching box. The crushing motor rotates, driving the crushing rollers to rotate, and driving the two crushing rollers to rotate simultaneously through the crushing gears to crush the edge banding that is unqualified after hot bending.

[0010] Further, the hot folding device further includes a lower sliding plate fixedly mounted on the upper track plate. A plurality of heating tubes are fixedly mounted on the bending arc plate. A camera bracket is fixedly mounted on the upper track plate. A camera is fixedly mounted on the camera bracket. Two ejecting electric cylinders are fixedly mounted on the upper track plate.

[0011] Further, a dropping groove is provided on the upper track plate, and two groups of arc grooves are symmetrically provided on the upper track plate. Each group of arc grooves is composed of three arc grooves.

[0012] Further, a clamping edge mechanism is provided on the inner rotating rod. The clamping edge mechanism includes an outer clamping plate fixedly mounted on the inner rotating rod. Three upper sliding columns are slidably mounted on the outer clamping plate. A movable clamping plate is fixedly mounted on the upper sliding columns. A sliding column spring is provided between the upper sliding columns and the outer clamping plate. A push block is fixedly mounted on the middle upper sliding column. A push column is fixedly mounted on the push block. The push column is slidably mounted on the outer clamping plate. The outer clamping plate slides in the arc groove.

[0013] Further, three ejecting columns are slidably mounted on the outer clamping plate. An ejecting column spring is provided between the ejecting columns and the outer clamping plate.

[0014] During use, place the edge banding strip between the outer clamping plate and the movable clamping plate of the two clamping mechanisms. By manually pushing the push post, the movable clamping plate and the outer clamping plate can be opened. At this time, insert the edge banding strip. Subsequently, the edge banding strip is clamped under the action of the sliding post spring, and at the same time, the top post spring causes the top post to hold the edge banding strip against it.

[0015] Further, the bending device further includes a first electric cylinder fixedly installed on the upper sliding plate. A second electric cylinder is fixedly installed on the base frame. A retracting rod is fixedly installed at the top of the second electric cylinder. An outer top post and an inner top post are fixedly installed on the retracting rod. The outer top post is fixedly installed with the slider. The inner pressing block is fixedly installed with the output end of the first electric cylinder. Two fixed posts are fixedly installed on the upper sliding plate.

[0016] Further, convex posts are provided on the outer pressing block, the secondary outer pressing block, the secondary inner pressing block and the inner pressing block. A tension spring is provided between the convex post of the outer pressing block and the fixed post. A chute rod is slidably installed outside the convex posts of the outer pressing block, the secondary outer pressing block, the secondary inner pressing block and the inner pressing block. A chute is provided on the chute rod. The convex posts of the outer pressing block, the secondary outer pressing block, the secondary inner pressing block and the inner pressing block slide in the chute of the chute rod.

[0017] When the first electric cylinder extends, it drives the inner pressing block to slide inward along the upper sliding plate. The inner pressing block contacts the edge banding strip and initially bends the edge banding strip. At this time, due to the action of the tension spring, the outer pressing block does not move, and the secondary outer pressing block and the secondary inner pressing block are pulled by the chute rod to slide slightly. Subsequently, the second electric cylinder contracts, driving the retracting rod to move inward, thereby driving the outer top post and the inner top post to move inward. The outer top post drives the slider to slide, thereby driving the inner rotating rod to move through the sliding rod, thereby driving the outer clamping plate to slide in the arc-shaped groove, and starting to bend the two ends of the edge banding strip through the clamping mechanism. When the inner top post contacts the outer pressing block, it pushes the outer pressing block to slide inward, the tension spring is stretched, and it drives the secondary outer pressing block and the secondary inner pressing block to slide inward simultaneously under the action of the chute rod. Finally, the edge banding strip is attached to the bending arc-shaped plate, and the inner pressing block, the secondary inner pressing block, the secondary outer pressing block and the outer pressing block are all attached to the edge banding strip. The edge banding strip is heat-bent by the heating tube, and at this time, the top post contacts the output end of the top-opening electric cylinder. After the edge banding strip is bent, it is located above the dropping groove. When the heat bending of the edge banding strip is completed, the camera is used to detect the edge banding strip to determine whether the heat bending is qualified. Subsequently, the top-opening electric cylinder extends, pushing the push post, the push block and the movable clamping plate to move outward, so that the movable clamping plate no longer clamps the edge banding strip. Subsequently, the first electric cylinder contracts and the second electric cylinder extends, so that the inner pressing block, the secondary inner pressing block, the secondary outer pressing block and the outer pressing block are separated from the edge banding strip, and the edge banding strip drops through the dropping groove.

[0018] The beneficial effects of the present invention compared with the prior art are as follows: (1) The two clamping edge mechanisms provided by the present invention can clamp both ends of the edge banding strip, facilitating the hot bending of the edge banding strip. At the same time, when the edge banding is completed, the clamping edge mechanism can automatically open, enabling the hot-bent edge banding strip to fall into the dropping slot, realizing automatic discharging; (2) The inner pressing block provided by the present invention first performs the first-step hot pressing on the edge banding strip, and then the outer pressing block, the secondary outer pressing block, and the secondary inner pressing block perform sequential hot pressing on the edge banding strip, and cooperate with the arc rotation of the clamping edge mechanism to realize multi-level hot bending of the edge banding strip from the inside to the outside, with good hot bending effect; (3) The camera provided by the present invention can detect the edge banding strip after hot bending. For unqualified edge banding strips, they are put into the crushing mechanism through the switching frame for crushing, realizing waste recycling. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] As Figure 3 ,Figure 4 As shown, the main frame device further includes a switching box 102 slidably mounted on the chassis 101. The switching box 102 is divided into two chambers, a finished product chamber 1021 and a waste product chamber 1022. A switching electric cylinder 103 is fixedly mounted on the chassis 101.

[0036] As Figure 3 , Figure 4 As shown, the crushing mechanism includes a crushing box 111 fixedly mounted on the chassis 101. Two crushing rollers 109 are rotatably mounted on the crushing box 111. A crushing motor 108 is fixedly mounted on the crushing box 111. The motor shaft of the crushing motor 108 is fixedly mounted on one of the crushing rollers 109. Crushing gears 110 are fixedly mounted on both of the crushing rollers 109. The two crushing gears 110 mesh with each other.

[0037] The telescopic movement of the switching electric cylinder 103 can drive the switching box 102 and the side slider 106 to slide along the side guide rail 105. When the camera 205 detects that the edge banding 4 is thermally bent qualified, the switching electric cylinder 103 does not act. The thermally bent edge banding 4 falls into the finished product chamber 1021 and lands on the chassis 101. Subsequently, the switching electric cylinder 103 contracts, and the edge banding 4 is brought to the unloading slope 104 through the switching box 102. The edge banding 4 leaves through the unloading slope 104. If the camera 205 detects that the edge banding 4 is thermally bent unqualified, the switching electric cylinder 103 first contracts, and then the edge banding 4 falls into the waste product chamber 1022. Subsequently, the switching electric cylinder 103 extends, and the edge banding 4 is pushed into the crushing box 111 through the switching box 102. The crushing motor 108 rotates, driving the crushing rollers 109 to rotate. The two crushing rollers 109 are driven to rotate simultaneously through the crushing gears 110 to crush the thermally bent unqualified edge banding 4.

[0038] As Figures 5-8 As shown, the thermal folding device further includes a lower sliding plate 218 fixedly mounted on the upper track plate 107. A plurality of heating tubes 202 are fixedly mounted on the bending arc plate 201. A camera bracket 204 is fixedly mounted on the upper track plate 107. A camera 205 is fixedly mounted on the camera bracket 204. Two ejecting electric cylinders 203 are fixedly mounted on the upper track plate 107;

[0039] As Figures 5-8 As shown, a dropping groove 220 is provided on the upper track plate 107. Two groups of arc grooves 219 are symmetrically provided on the upper track plate 107. Each group of arc grooves 219 is composed of three arc grooves.

[0040] As Figures 5-8As shown in the figure, a clamping edge mechanism is provided on the inner rotating rod 209. The clamping edge mechanism includes an outer clamping plate 210 fixedly installed on the inner rotating rod 209. Three upper sliding columns 212 are slidably installed on the outer clamping plate 210. An active clamping plate 211 is fixedly installed on the upper sliding columns 212. A sliding column spring 213 is provided between the upper sliding columns 212 and the outer clamping plate 210. A pushing block 214 is fixedly installed on the middle upper sliding column 212. A pushing column 215 is fixedly installed on the pushing block 214. The pushing column 215 is slidably installed with the outer clamping plate 210, and the outer clamping plate 210 slides in the arc-shaped groove 219.

[0041] As Figures 5-8 shown, three top columns 216 are slidably installed on the outer clamping plate 210. A top column spring 217 is provided between the top columns 216 and the outer clamping plate 210.

[0042] During use, place the edge banding strip 4 between the outer clamping plate 210 and the active clamping plate 211 of the two clamping edge mechanisms. By manually pushing the pushing column 215, the active clamping plate 211 and the outer clamping plate 210 can be opened. At this time, insert the edge banding strip 4. Subsequently, the edge banding strip 4 is clamped under the action of the sliding column spring 213, and at the same time, the top column spring 217 causes the top column 216 to hold the edge banding strip 4.

[0043] As Figure 9 、 Figure 10 shown, the bending device further includes a first electric cylinder 308 fixedly installed on the upper sliding plate 301. A second electric cylinder 302 is fixedly installed on the base frame 101. A retracting rod 303 is fixedly installed at the top of the second electric cylinder 302. An outer top column 304 and an inner top column 305 are fixedly installed on the retracting rod 303. The outer top column 304 is fixedly installed with the slider 208. The inner pressing block 313 is fixedly installed at the output end of the first electric cylinder 308. Two fixed columns 306 are fixedly installed on the upper sliding plate 301.

[0044] As Figure 9 、 Figure 10 shown, convex columns are provided on the outer pressing block 310, the secondary outer pressing block 311, the secondary inner pressing block 312, and the inner pressing block 313. A tension spring 307 is provided between the convex column of the outer pressing block 310 and the fixed column 306. A chute rod 309 is slidably installed outside the convex columns of the outer pressing block 310, the secondary outer pressing block 311, the secondary inner pressing block 312, and the inner pressing block 313. A chute is provided on the chute rod 309. The convex columns of the outer pressing block 310, the secondary outer pressing block 311, the secondary inner pressing block 312, and the inner pressing block 313 slide in the chute of the chute rod 309.

[0045] The first electric cylinder 308 extends to drive the inner pressing block 313 to slide inward along the upper slide plate 301. The inner pressing block 313 contacts the edge banding strip 4 and initially bends the edge banding strip 4. At this time, due to the action of the tension spring 307, the outer pressing block 310 does not move, and the secondary outer pressing block 311 and the secondary inner pressing block 312 are pulled by the chute rod 309 to slide slightly. Subsequently, the second electric cylinder 302 contracts, driving the retracting rod 303 to move inward, thereby driving the outer ejector pin 304 and the inner ejector pin 305 to move inward. The outer ejector pin 304 drives the slider 208 to slide, thereby driving the inner rotating rod 209 to move through the sliding rod 207, and then driving the outer clamping plate 210 to slide in the arc-shaped groove 219, and starting to bend both ends of the edge banding strip 4 through the edge clamping mechanism. When the inner ejector pin 305 contacts the outer pressing block 310, it pushes the outer pressing block 310 to slide inward, the tension spring 307 is stretched, and under the action of the chute rod 309, it drives the secondary outer pressing block 311 and the secondary inner pressing block 312 to slide inward simultaneously, finally making the edge banding strip 4 fit with the bending arc plate 201, and the inner pressing block 313, the secondary inner pressing block 312, the secondary outer pressing block 311, and the outer pressing block 310 all fit with the edge banding strip 4. The edge banding strip 4 is heat-bent by the heating tube 202, and at this time, the ejector pin 216 contacts the output end of the ejecting electric cylinder 203. After the edge banding strip 4 is bent, it is located above the dropping groove 220. When the heat bending of the edge banding strip 4 is completed, the camera 205 is used to detect the edge banding strip 4 to determine whether the heat bending is qualified. Subsequently, the ejecting electric cylinder 203 extends, pushing the ejecting column 215, the pushing block 214, and the movable clamping plate 211 to move outward, so that the movable clamping plate 211 no longer clamps the edge banding strip 4. Subsequently, the first electric cylinder 308 contracts, and the second electric cylinder 302 extends, so that the inner pressing block 313, the secondary inner pressing block 312, the secondary outer pressing block 311, and the outer pressing block 310 are separated from the edge banding strip 4, and the edge banding strip 4 drops through the dropping groove 220.

[0046] The working principle of a hot bending device for arc edge banding strips with waste recycling disclosed in the present invention is as follows: During use, place the edge banding strip 4 between the outer clamping plate 210 and the movable clamping plate 211 of the two clamping mechanisms. By manually pushing the push column 215, the movable clamping plate 211 and the outer clamping plate 210 can be opened. At this time, insert the edge banding strip 4, and then the edge banding strip 4 is clamped under the action of the sliding column spring 213. At the same time, the top column spring 217 causes the top column 216 to hold the edge banding strip 4. The first electric cylinder 308 extends to drive the inner pressing block 313 to slide inward along the upper sliding plate 301. The inner pressing block 313 contacts the edge banding strip 4 and initially bends the edge banding strip 4. At this time, due to the action of the tension spring 307, the outer pressing block 310 does not move, and the secondary outer pressing block 311 and the secondary inner pressing block 312 are pulled by the chute rod 309 to slide slightly. Subsequently, the second electric cylinder 302 contracts, driving the retracting rod 303 to move inward, thereby driving the outer top column 304 and the inner top column 305 to move inward. The outer top column 304 drives the slider 208 to slide, thereby driving the inner rotating rod 209 to move through the sliding rod 207, and then driving the outer clamping plate 210 to slide in the arc-shaped groove 219, starting to bend the two ends of the edge banding strip 4 through the clamping mechanism. When the inner top column 305 contacts the outer pressing block 310, it pushes the outer pressing block 310 to slide inward, and the tension spring 307 is stretched. Under the action of the chute rod 309, it drives the secondary outer pressing block 311 and the secondary inner pressing block 312 to slide inward simultaneously, finally making the edge banding strip 4 fit with the bending arc-shaped plate 201, and the inner pressing block 313, the secondary inner pressing block 312, the secondary outer pressing block 311, and the outer pressing block 310 all fit with the edge banding strip 4. Heat the edge banding strip 4 through the heating pipe 202 for hot bending. At this time, the top column 216 contacts the output end of the ejecting electric cylinder 203. After the edge banding strip 4 is bent, it is located above the dropping groove 220. When the hot bending of the edge banding strip 4 is completed, use the camera 205 to detect the edge banding strip 4 to determine whether the hot bending is qualified. Subsequently, the ejecting electric cylinder 203 extends, pushing the push column 215, the push block 214, and the movable clamping plate 211 to move outward, so that the movable clamping plate 211 no longer clamps the edge banding strip 4. Then the first electric cylinder 308 contracts, and the second electric cylinder 302 extends, causing the inner pressing block 313, the secondary inner pressing block 312, the secondary outer pressing block 311, and the outer pressing block 310 to disengage from the edge banding strip 4. The edge banding strip 4 drops through the dropping groove 220.The telescopic movement of the switching cylinder 103 can drive the switching frame 102 and the side slider 106 to slide along the side guide rail 105. When the camera 205 detects that the hot bending of the edge banding strip 4 is qualified, the switching cylinder 103 does not act, and the edge banding strip 4 after hot bending falls into the finished product cavity 1021 and lands on the chassis 101. Subsequently, the switching cylinder 103 contracts, and the edge banding strip 4 is brought to the discharge slope 104 through the switching frame 102, and the edge banding strip 4 leaves through the discharge slope 104. If the camera 205 detects that the hot bending of the edge banding strip 4 is unqualified, the switching cylinder 103 first contracts, and then the edge banding strip 4 falls into the waste product cavity 1022. Subsequently, the switching cylinder 103 extends, and the edge banding strip 4 is pushed into the crushing box 111 through the switching frame 102. The crushing motor 108 rotates, driving the crushing roller 109 to rotate, and driving the two crushing rollers 109 to rotate simultaneously through the crushing gear 110 to crush the edge banding strip 4 with unqualified hot bending.

[0047] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope of the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
