Description

Technical Field

[0001] The invention relates to the technical field of edge banding hot bending, and in particular to an arc edge banding hot bending device with waste recovery function. 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 role of edge banding is not only aesthetic, it can also improve the durability, moisture resistance and wear resistance of the board, and prevent moisture, dust and bacteria from invading the edge of the wood. Edge banding is widely used in the production of furniture, cabinets, floors, doors and windows and other products. Edge banding hot bending refers to the process of heating the edge banding material to soften it and then bending it. This process is commonly used in furniture manufacturing and woodworking industries, especially when adding edge banding to the edges of wooden boards to ensure the beauty and durability of the edges. The hot bending process usually requires controlling the temperature and bending angle to ensure that the edge banding is not damaged and can be accurately attached to the edge of the board. The edge banding hot bending device in the prior art usually only performs hot bending on the two ends of the edge banding, and cannot perform multi-level hot bending on the edge banding. Compared with one-time hot bending, multiple hot bending in steps can improve the hot bending quality and reduce internal stress. At the same time, edge banding with poor hot bending quality needs to be recycled. Summary of the invention

When the camera detects that the edge banding strip is qualified for hot bending, the switching electric cylinder will not move, and the edge banding strip that has been hot bent will fall into the finished product cavity and onto the bottom frame. Then the switching electric cylinder will retract, and the edge banding strip will be brought to the discharge slope through the switching frame, and the edge banding strip will leave through the discharge slope. If the camera detects that the edge banding strip is unqualified for hot bending, the switching electric cylinder will retract first, and then the edge banding strip will fall into the waste cavity. Then the switching electric cylinder will extend, and the edge banding strip will be pushed into the crushing box through the switching frame. The crushing motor will rotate, driving the crushing roller to rotate, and the two crushing rollers will rotate at the same time through the crushing gear to crush the edge banding strip that does not meet the hot bending requirements.

[0013] The first electric cylinder extends and drives the inner pressure block to slide inward along the upper slide plate. The inner pressure block contacts the edge banding strip and performs a preliminary bending on the edge banding strip. At this time, due to the action of the tension spring, the outer pressure block will not move, and the secondary outer pressure block and the secondary inner pressure block are pulled by the slide groove rod to slide slightly. Then the second electric cylinder contracts, driving the retraction rod to move inward, thereby driving the outer push column and the inner push column to move inward. The outer push column 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 groove, and the two ends of the edge banding strip begin to bend through the edge clamping mechanism. When the inner push column contacts the outer pressure block, it pushes the outer pressure block to slide inward, and the tension spring is stretched, and under the action of the slide groove rod, the secondary outer pressure block and the secondary inner pressure block are pulled inward. The inner pressure block slides inwards at the same time, and finally the edge banding strip is fitted with the bent arc plate, and the inner pressure block, the secondary inner pressure block, the secondary outer pressure block and the outer pressure block are all fitted with the edge banding strip, and the edge banding strip is hot bent by the heating tube, and at this time the push column contacts the output end of the push-up electric cylinder, and the edge banding strip is located above the drop groove after bending. When the hot bending of the edge banding strip is completed, the edge banding strip is inspected by the camera to determine whether the hot bending is qualified, and then the push-up electric cylinder is extended to push the push column, the push block and the movable splint to move outward, so that the movable splint no longer clamps the edge banding strip, and then the first electric cylinder contracts and the second electric cylinder extends, so that the inner pressure block, the secondary inner pressure block, the secondary outer pressure block and the outer pressure block are separated from the edge banding strip, and the edge banding strip falls through the drop groove.

[0038] The working principle of the arc edge strip hot bending device with waste recovery disclosed in the present invention is: when in use, the edge strip 4 is placed between the outer clamping plate 210 and the movable clamping plate 211 of the two clamping mechanisms, and the movable clamping plate 211 and the outer clamping plate 210 can be opened by manually pushing the push column 215. At this time, the edge strip 4 is inserted, and then the edge strip 4 is clamped under the action of the sliding column spring 213, and at the same time, the top column spring 217 enables the top column 216 to support the edge strip 4. The first electric cylinder 308 extends and drives the inner pressure block 313 to slide inward along the upper slide plate 301. The inner pressure block 313 contacts the edge banding strip 4 and performs a preliminary bend on the edge banding strip 4. At this time, due to the action of the tension spring 307, the outer pressure block 310 does not move. The secondary outer pressure block 311 and the secondary inner pressure block 312 are pulled by the slide groove rod 309 to slide slightly. Then the second electric cylinder 302 contracts, driving the retraction rod 303 to move inward, thereby driving the outer push column 304 and the inner push column 310 to move inward. The column 305 moves inward, and 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, thereby driving the outer clamping plate 210 to slide in the arc groove 219, and the two ends of the edge banding strip 4 begin to bend through the edge clamping mechanism. When the inner top column 305 contacts the outer pressure block 310, the outer pressure block 310 is pushed to slide inward, and the tension spring 307 is stretched, and under the action of the sliding groove rod 309, the secondary outer pressure block 311 and the secondary The inner pressing block 312 slides inward at the same time, and finally the edge strip 4 is fitted with the bent 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 are all fitted with the edge strip 4, and the edge strip 4 is hot-bent by the heating tube 202, and at this time, the top column 216 contacts the output end of the top-opening electric cylinder 203, and the edge strip 4 is bent and located above the drop groove 220.
