[0001] The present invention belongs to the technical field of edge banding, and particularly relates to an automatic edge banding device for PP honeycomb panels. Background Art

[0002] The characteristics of plastic honeycomb panels are mainly: waterproof, moisture-proof, and their structure is honeycomb-shaped, so they are light in weight and have the advantages of shock resistance, heat preservation, heat insulation, sound insulation, etc. However, the appearance effect of the edge surface structure of plastic honeycomb panels is poor, and generally, an edge banding machine is used to decorate the edge surface of plastic honeycomb panels.

[0003] Currently, in the prior art, an edge banding machine is used to edge band plastic honeycomb panels. However, most of the existing edge banding machines are completed in the form of adhesive edge banding, with low accuracy in guiding and positioning the edge banding tape, and the edge banding is not firm, thus affecting the edge banding quality. Moreover, when in use, it is also necessary to manually rotate the plastic honeycomb panel, and the automation efficiency is not high. Therefore, in view of the above problems, an edge banding device that can automatically complete the edge banding of plastic honeycomb panels is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic edge banding device for PP honeycomb panels to overcome the deficiencies of the prior art, which can fully automatically realize the edge banding operation of PP honeycomb panels, with high edge banding efficiency and good edge banding quality, meeting the requirements of the high-quality development of enterprises.

[0056] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0057] The present invention provides an automatic edge-sealing device for PP honeycomb panels to solve the problems of low operation efficiency and poor edge-sealing quality when using an edge-sealing machine for edge-sealing operations on PP honeycomb panels in the prior art, where glue bonding is used.

[0058] Refer to Figure 21 , the object of the present invention is to seal the edge strip 6 sleeved on the four sides of the product 5 around the product.

[0059] For ease of understanding, the specific process in the embodiments of this application will be described below. Please refer to Figures 1 to 3, An automatic edge-sealing device for PP honeycomb boards in an embodiment of the present application includes a frame 1; a rotary positioning module 2, a shaping device 3, and a pre-pressing and welding device 4 are sequentially arranged on the frame 1; a slidable shaping device 3 and a pre-pressing and welding device 4 are arranged on one side of the rotary positioning module 2. The shaping device 3 includes a clamping mechanism 3a and a wrap strip shaping mechanism 3b that can be telescoped on one side of the clamping mechanism 3a.

[0060] Among them, when the rotary positioning module 2 positions the product 5 sleeved with a wrap strip 6 and rotates it to a set angle, the shaping device 3 and the pre-pressing and welding device 4 slide synchronously until one side of the product located in the rotary positioning module 2 is within the clamping mechanism 3a. Then, the clamping mechanism 3a clamps and shapes the product, and the wrap strip shaping mechanism 3b shapes the wrap strip. The pre-pressing and welding device 4 moves to one side of the wrap strip to pre-press the wrap strip. Then, the wrap strip shaping mechanism 3b returns to its original position. Finally, the pre-pressing and welding device 4 heats the product and the wrap strip up and down and then cools and solidifies them to complete the edge-sealing operation on one side of the product and the wrap strip.

[0061] The automatic edge-sealing device for PP honeycomb boards of the present invention automatically completes the four-side edge-sealing operation of the product and the wrap strip by the rotary positioning module, the shaping device 3, and the pre-pressing and welding device 4 after manually assisting in sleeving the wrap strip on the product. The edge-sealing operation is completed automatically, with high efficiency, and the quality of the edge-sealing can also be effectively guaranteed, meeting the production and processing requirements of enterprises.

[0062] Refer to Figures 2 to 6 , In this embodiment, the rotary positioning module 2 includes a rotatable indexing turntable 20. An elevating carrier plate 21 is arranged on the indexing turntable 20. A plurality of vacuum suction holes 22 for adsorbing the product 5 are provided on the carrier plate 21, so as to quickly fix the product 5 without causing damage to the product 5. Push components 23 are arranged on the four sides at the bottom of the carrier plate 21. The four push components 23 are respectively used to push the positioning components 24 located on the four sides of the carrier plate 21 to move back and forth. The four positioning components 24 are used to automatically center-position the product 5 arranged on the carrier plate 21.

[0063] Specifically, the positioning component 24 includes a vertically arranged slide rail 240 that can be pushed back and forth by the push component 23. A slider 241 that can move up and down is arranged on the slide rail 240. A positioning plate 243 that can move up and down driven by a jacking cylinder 242 is arranged on the slider 241. A support plate 244 is arranged above the side of the slide rail opposite to the positioning plate. A plurality of universal ball rollers 245 are arranged on the support plate 244 for carrying the product 5. The universal ball rollers 245 will not cause frictional damage to the product.

[0064] In addition, in this embodiment, two pushing components 23 are provided on each side of the bearing platen 2. In this way, the two pushing components 23 are taken as a group, and a group of pushing components 23 is provided on each side to push the positioning component to move back and forth. The pushing component 23 can be a pushing cylinder, and the product 5 is pushed to be centered by the pushing cylinder. Of course, the pushing component 23 can also be other driving components as long as it can drive the product 5 to be centered.

[0065] During operation, first, the edge strip 6 is manually sleeved on the four sides of the product 5. Then, the bearing platen 21 drives the product 5 to descend, so that the bottom surface of the product 5 is supported by a plurality of universal ball rollers 245 on the four sides. Next, the pushing component 23 drives the positioning component 24 to push forward. After the positioning plate 243 moves forward a certain distance, the positioning plate 243 is located outside the product 5. Then, the lifting cylinder 242 drives the slider 241 to drive the positioning plate 243 to move upward in the slide rail 240 until the positioning plate 243 and the four sides of the product 5 are on the same plane. Then, the pushing component 23 retracts, and the positioning plates 243 on the four sides push the four sides of the product to move, thereby realizing the centering of the product 5.

[0066] In addition, in order to be able to adjust the pushing distance of the pushing component 23 so as to adapt to the centering of products of different specifications, the pushing component 23 is slidably arranged on the adjusting slider 230, and the adjusting slider 230 is slidably arranged on the adjusting slide rail 231; a rack 232 is connected to one side of the pushing component; a gear 233 meshing with the rack 232 is provided on the rack 232, and the gear 233 can be driven to rotate on the rack 232 via a transmission mechanism by a handwheel 234, thereby driving the pushing component 23 connected to the rack to slide on the adjusting slide rail 231; in this way, during operation, the handwheel 234 drives the gear 233 to rotate, the rotation of the gear 233 drives the rack 232 to move, and the rack 232 is arranged on the pushing component, so the position of the pushing component 23 can be adjusted, thereby adapting to the centering of products of different specifications.

[0067] Furthermore, in this embodiment, first synchronous rollers 235 are provided on the handwheels 234 corresponding to the pushing components 23 on the left and right sides, and the first synchronous rollers 235 are connected by a first synchronous belt 236. In this way, the positions of all the pushing components 23 on the left and right sides can be synchronously adjusted by one handwheel 234.

[0068] Similarly, second synchronous rollers 237 are provided on the handwheels 234 corresponding to the pushing components 23 on the front and rear sides, and the second synchronous rollers 237 are connected by a second synchronous belt 238. In this way, the positions of the pushing components 23 on the front and rear sides can be synchronously adjusted by one handwheel; in summary, the position of the pushing component 23 can be adjusted by the handwheel 234 to adapt to the centering of products of different specifications.

[0069] Refer to Figures 7 to 13 Figures 7 to 13 , as a further preferred embodiment, the shaping device 3 includes a shaping frame 30 disposed on the frame 1; upper and lower clamping blocks 31 and 32 capable of relatively sliding are provided in the vertical direction on both sides of the shaping frame 30, and the surfaces of the upper and lower clamping blocks 31 and 32 have protrusions 310. After the two vertically opposite protrusions 310 are pressed together, the product is clamped, and at the same time, the upper and lower surfaces of the product can be shaped.

[0070] In addition, edge-blocking blocks 33 are provided in the length direction on the outer sides of the upper and lower clamping blocks 31 and 32, and the edge-blocking blocks 33 are telescopically moved back and forth in the horizontal direction of the upper and lower clamping blocks 31 and 32 through an adjusting mechanism 35. During operation, the upper and lower surfaces of the product are shaped by the upper and lower clamping blocks 31 and 32, while the two edge-blocking blocks 33 shape the bending of the edge strip 6.

[0071] Further, shaping slide rails 36 are provided in the vertical direction on both sides of the shaping frame 30, and upper and lower corresponding upper sliders 37a and lower sliders 37b are respectively provided on the two shaping slide rails 36; the upper sliders 37a and lower sliders 37b are respectively driven by two shaping cylinders 38 to move up and down in the shaping slide rails 36; the upper and lower clamping blocks 31 and 32 are respectively disposed in the upper sliders 37a and lower sliders 37b. In this way, the corresponding upper sliders 37a and lower sliders 37b are driven by the two shaping cylinders 38 to move up and down. The driving is fast, accurate and effective, and the upper and lower sliders move linearly in a straight line. Therefore, after the product is clamped by the upper and lower clamping blocks, the shaping operation of the upper and lower surfaces of the product can be well realized; at the same time, the two shaping cylinders 38 are both disposed above the frame 1, so as to facilitate maintenance and replacement.

[0072] Further, the number of the adjusting mechanisms 35 is two, and the two adjusting mechanisms 35 are respectively disposed on one side of the upper slider 37a and the lower slider 37b; the two adjusting mechanisms 35 respectively include mounting blocks 350 disposed along the length direction of the upper slider 37a and the lower slider 37b, a plurality of spaced-apart pushing blocks 351 are provided on the mounting blocks 350, and inclined surfaces 352 inclined in the same direction are provided on the opposite sides of two adjacent pushing blocks 351; two pushing cylinders 353 are provided on both the upper slider 37a and the lower slider 37b. One pushing cylinder 353 is connected to one pushing block 351 on one side, and the other pushing cylinder 353 is located on the opposite side of the pushing block 351 on the other side, and a telescopic block corresponding to the pushing block is provided on the telescopic rod of the pushing cylinder 353.

[0073] On the relative sides of the two mounting blocks 350, there are moving bars 354 arranged along the length direction of the mounting blocks 350. On the moving bars 354, there are guide posts 355 located between adjacent pushing blocks 351. Among them, the rightmost guide post 355 is located between the pushing block 351 and the telescopic block; in the vertical direction of the moving bar 354, there are multiple connecting posts 356 arranged in parallel and passing through the upper sliding block 37a and the lower sliding block 37b. The connecting posts 356 passing through the upper sliding block 37a and the lower sliding block 37b are respectively connected to the corresponding edge blocking blocks 33; between the two edge blocking blocks 33 and the upper and lower sliding blocks, there are springs 357 connected.

[0074] During operation, when the left pushing cylinder 353 pushes multiple pushing blocks 351 to move synchronously to the right, the guide posts 355 slide along the inclined surfaces 352 on the pushing blocks 351, causing the guide posts 355 to move backward along the inclined surfaces. The guide posts 355 are arranged on the moving bars 354, and the moving bars 354 are connected to the edge blocking blocks 33 through the connecting posts 356; thus, when the guide posts 355 move backward along the inclined surfaces, they synchronously drive the edge blocking blocks 33 to retract, and at the same time, the springs 357 are stretched; when the right pushing cylinder 353 pushes multiple pushing blocks 351 to move synchronously to the left, the guide posts move forward along the inclined surfaces of the pushing blocks, thereby driving the edge blocking blocks to move forward, and at the same time, the springs reset, realizing the forward and backward telescopic movement of the edge blocking blocks 33. The function of the edge blocking blocks 33 is to straighten the edge wrapping strip to prevent it from being distorted; in addition, the retractable setting of the edge blocking blocks 33 can avoid interference when the subsequent pre-pressing and welding device 4 works.

[0075] Refer to Figures 14 to 19 In this embodiment, the pre-pressing and welding device 4 includes a welding bracket 40 that is slidably arranged on one side of the shaping device 3. The welding bracket 40 slides horizontally through a transverse movement module 47. In the vertical direction of the welding bracket 40, there are an upper heating mold 41 and a lower heating mold 42 that can slide relatively up and down through a driving mechanism 49. One of the opposite surfaces of the upper heating mold 41 and the lower heating mold 42 is an arc surface 43 adapted to the product corner; between the upper heating mold 41 and the lower heating mold 42, there is a curing cold mold 44. The curing cold mold 44 is U-shaped and can move back and forth in the horizontal direction between the upper heating mold and the lower heating mold; inside the U-shaped opening of the curing cold mold 44, there are multiple pre-pressing plates 46 that are telescopic and distributed along the length direction of the fixed cold mold 44. During operation, the upper heating mold 41 and the lower heating mold 42 move up and down to heat the product and the edge wrapping strip to make them soften, and then the retractable curing cold mold 44 cools and shapes the product and the edge wrapping strip.

[0076] Among them, a cold mold pushing cylinder 401 is provided on the welding bracket 40, and the cold mold pushing cylinder 401 drives the pushing plate 402 to move forward, and the pushing plate 402 is connected to the curing cold mold 44 through the guide column 403 passing through the welding bracket 40; a plurality of pre-stressing cylinders 404 are provided in the length direction of the pushing plate 402; the pre-stressing cylinder passes through the welding bracket and is connected to the driving plate 405, and a plurality of pushing rods 407 connected to the pre-stressing spring 406 are provided in the length direction of the driving plate 405, and the pushing rod 407 passes through the U-shaped mouth of the fixed cold mold, and the front end of the pushing rod 407 is connected to the pre-stressing plate 46.

[0077] During operation, when the edge block 33 shrinks back to avoid, the pre-stressing plate 46 first pre-stresses the edging strip, and then the upper heating mold 41 and the lower heating mold 42 move in the same direction to heat and soften the product and the edging strip, and then the cold mold push cylinder 401 drives the pushing plate forward, and the pushing plate 402 drives the curing cold mold 44 forward. After the curing cold mold 44 moves forward, the product 5 and the edging strip 6 are cured and formed. Among them, the pre-stressing plate is always in a state of pre-stressing the edging strip under the action of the pre-stressing spring to ensure that the edging strip 6 fits well on the product.

[0078] Furthermore, the driving mechanism 49 includes a driving motor 490, which synchronously drives two relatively arranged screw rods 492 to rotate through a synchronous belt 491, and two relatively arranged sliding blocks 493 are arranged on the screw rod 492. The two sliding blocks 493 follow the screw rod 492 to move in the same direction or in the opposite direction. The upper heating mold and the lower heating mold are respectively arranged on the two sliding blocks 493, thereby realizing the heating and lubrication of the product after the upper and lower heating molds 41 and 42 are tightened up and down.

[0079] During operation, the driving mechanism 49 drives the upper heating mold 41 and the lower heating mold 42 to rise and fall synchronously, thereby heating and softening the product and the edge strip.

[0080] The specific process of the present invention is described below:
