Description

Technical Field

[0001] The present invention relates to the field of packaging carton processing, and more specifically to a packaging carton and its processing method. Background Art

[0002] During the logistics transportation process, cartons, as common packaging materials, are widely used to protect goods from collision and extrusion. However, when traditional corrugated cartons are subjected to external impacts, their buffering performance is limited. Especially for fragile or precision items, it is difficult to provide sufficient protection only relying on the strength of the carton itself. Currently, some improvement solutions enhance the buffering effect by adding foam liners inside the cartons, but these methods usually rely on manual operations, with low efficiency and poor adaptability. And some goods have a certain impact resistance, so using foam liners to package such goods will increase costs. Summary of the Invention

[0025] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] As Figure 3 and Figure 4 , to increase the anti-collision effect of the packaging carton.

[0028] The rotating frame 11 is located above the inside of the support frame 14, and the support disk 12 is located below the inside of the support frame 14. Two push plates 101 are oppositely arranged on the rotating frame 11. The push plate 101 is slidably connected to the rotating frame 11. Four clamping blocks 103 are slidably connected to the rotating frame 11. Two clamping blocks 103 are symmetrically arranged on both sides of each push plate 101. A turntable is rotatably connected to each clamping block 103, and two clamping rods 104 are fixedly connected to each turntable. Four sliding grooves 206 are provided on the support disk 12. A supporting block 203 is provided in each sliding groove 206, and a supporting rod 204 is rotatably connected to each supporting block 203.

[0029] When the device works, the support disk 12 is driven to move upward, so that the four support rods 204 move into the corrugated carton. Then, the four support blocks 203 are driven to move outward synchronously, thereby driving the four support rods 204 to move synchronously. At this time, the four support rods 204 support the carton at the four sides. At the same time, two corrugated cardboard sheets slightly longer than the width of the carton are respectively fixed between the two clamping rods 104 on both sides. At this time, the two push plates 101 are located inside. Then, the two push plates 101 are driven to move outward, thereby squeezing the cardboard into an arc shape so that its width is the same as the width of the carton. Then, the rotating frame 11 is driven to move downward, thereby driving the cardboard to move into the carton. Then, the rotating frame 11 is moved in the reverse direction to reset. Similarly, two cardboard sheets slightly longer than the length of the carton are placed, so that the two push plates 101 are located outside. Then, the two push plates 101 are driven to move inward simultaneously, and the above steps are repeated to place the cardboard in the carton. At this time, the edges of the four cardboard sheets are mutually squeezed so that they are not easy to move, thereby enabling the inside of the carton to be supported by the four cardboard sheets, preventing the goods placed therein from directly contacting the four walls of the carton, providing support for the goods, and thus increasing its safety during transportation and avoiding damage to the internal goods caused by collision. For goods that are more likely to be damaged, foam cushions can also be provided inside. This carton can further increase the safety of the internal goods.

[0030] AsFigures 5 to 7 , to solve the problem of fixing the cardboard by the clamping rod 104.

[0031] A connecting rod 102 is rotatably connected between each supporting block 203 and the corresponding pushing plate 101. A double-acting air cylinder 106 is fixedly connected below the rotating frame 11. The moving ends of the double-acting air cylinder 106 are respectively fixedly connected to the two pushing plates 101. A torsion spring 105 is fixedly connected between each turntable and the corresponding clamping block 103.

[0032] Referring to the two clamping blocks 103 on the same side of the pushing plate 101 in the figure. Initially, the two clamping blocks 103 are relatively far away from each other. At this time, the gaps between the two clamping rods 104 below each clamping block 103 are in the same straight line. After placing the cardboard in the two gaps, drive the double-acting air cylinder 106 to extend or shorten, thereby driving the pushing plate 101 to move. The pushing plate 101 and the two clamping blocks 103 are both connected by the connecting rod 102, thereby driving the two clamping blocks 103 to move synchronously inward. When the cardboard is squeezed into an arc, it is possible to prevent relative sliding between the clamping block 103 and the cardboard, thereby preventing the cardboard from falling off. At the same time, since the cardboard is bent, an angle is generated between the cardboard and the clamping block 103. A turntable is arranged above the two corresponding clamping rods 104, thereby driving the turntables above the two clamping rods 104 to rotate, preventing the clamping rod 104 from damaging the cardboard. Also, since a torsion spring 105 is arranged between the turntable and the clamping block 103, the compressed torsion spring 105 can provide a force for the clamping rod 104 to rotate in the reverse direction, thereby increasing the friction between the clamping rod 104 and the cardboard, thus preventing the cardboard from falling off when the rotating frame 11 drives the cardboard to move downward. At the same time, the torsion spring 105 can also facilitate the turntable to drive the clamping rod 104 thereon to reset, facilitating the subsequent placement of the cardboard in the gap thereon.

[0033] Such as Figure 8 , to solve the problem of supporting the cardboard box by the support rod 204.

[0034] A track ring 201 is welded on the support disk 12. The rotating block 202 is slidably arranged in the track ring 201. A tension spring 205 is fixedly connected between each rotating block 202 and the track ring 201. A compression spring is arranged between each rotating block 202 and the corresponding supporting block 203.

[0035] The processed carton is generally in a compressed state, and the present invention first slightly props up the carton, and then moves the support plate 12 upward to drive the four support rods 204 to be inserted into the carton. Initially, the compression springs are all in a compressed state, and then the four support blocks 203 are located on the inner side of the support plate 12. Then the compression springs are released, and the compression springs push the support blocks 203 to move outward, and then drive the support rods 204 to move outward, and then the support rods 204 move to the four corners of the carton, and then the carton is propped open and fixed. The support rods 204 and the support blocks 203 are rotatably connected to each other, so as to prevent the support rods 204 from rubbing against the carton when moving close to the inner wall of the carton, thereby causing damage to the carton.

[0036] like Figure 8 , to solve the problem of fixing cartons of different sizes.

[0037] Each slide groove 206 includes a card slot, a straight slot and a wide slot. The inner side of the slide groove 206 is a card slot. Each card slot is connected to a straight slot along the radial direction of the support plate 12. The angle between adjacent straight slots is 90°. The outer side of each straight slot is connected to the wide slot.

[0038] Initially, the support block 203 is located at the slot in the slide slot 206, which is slightly inclined outward. At the same time, the elastic force of the spring is greater than the elastic force of the tension spring 205, which makes it easier for the spring to push the support block 203 out of the slot. When the carton is square, four straight grooves are arranged along the diagonals of the square, and the tension spring 205 pulls the support block 203 to make it close to the front and rear directions, thereby ensuring that the four support rods 204 can support the four sides of the carton; when the carton is rectangular, its long side is placed along the left and right directions in the figure. At this time, when the support rods 204 on the front and rear sides contact the front and rear inner walls of the carton, the tension of the tension spring 205 makes the support rods 204 close to the front and rear inner walls, and then when the spring pushes the support rods 204 around, it moves outward along the long side inner walls of the front and rear sides until it stops when it moves to the four sides of the carton, and then supports the carton from the four sides, and the wide groove in the slide 206 reserves movement width in the front and rear and left and right directions, thereby being able to meet the support requirements of cartons with different aspect ratios.

[0039] like Figure 9 , in order to solve the problem of the support rod 204 moving and resetting.

[0040] Four first gas rods 13 are fixedly connected below the support plate 12 , and a push rod 301 is fixedly connected to the movable end of each first gas rod 13 . A guide wheel 302 is rotatably connected below each support block 203 , and each guide wheel 302 is in contact with the corresponding push rod 301 .

[0041] Initially, the first gas rod 13 is in a retracted state, so that the push rod 301 is against the guide wheel 302, so that the spring between the support block 203 and the rotating block 202 is in a compressed state. When supporting the carton, the first gas rod 13 is extended, thereby releasing the spring to drive the support rod 204 to support the carton. After the carton processing is completed, the first gas rod 13 is slightly retracted, and the guide wheel 302 is pushed toward the center. Similarly, the spring is compressed to reduce the supporting force around the carton, and then the support plate 12 is moved downward to make the carton detach from the support rod 204, and then the first gas rod 13 is further retracted to reset the support rod 204. The purpose of setting the guide wheel 302 is to convert the sliding friction between the support block 203 and the push rod 301 into rolling friction to reduce the resistance of the equipment.

[0042] like Figure 10 , in order to solve the problem of the rotating frame 11 and the supporting plate 12 moving up and down.

[0043] The bracket 14 is rotatably connected to two rotating shafts 401 , the rotating frame 11 is rotatably connected to a fixing plate 107 , a thread transmission is provided between the fixing plate 107 and one of the rotating shafts 401 , and a thread transmission is provided between the supporting plate 12 and the other rotating shaft 401 .

[0044] When one rotating shaft 401 is driven to rotate, the fixed plate 107 is driven to move up and down through the thread, thereby driving the rotating frame 11 to move up and down, and driving the other rotating shaft 401 to drive the supporting plate 12 to move up and down in the same way. The rotating frame 11 and the supporting plate 12 are arranged coaxially, thereby preventing the position of the cardboard from being offset when placed in the carton. At the same time, two electric cylinders can be respectively arranged to drive the fixed plate 107 and the supporting plate 12 to move up and down.

[0045] like Figure 10 , in order to solve the problem of rotation of the rotating frame 11.

[0046] A second gas rod 404 is fixedly connected to the bracket 14 , a rack 403 is fixedly connected to the movable end of the second gas rod 404 , the rack 403 is slidably connected to the bracket 14 , a gear 108 is fixedly connected to the rotating frame 11 , and the gear 108 meshes with the rack 403 by movement.

[0047] When the cardboard is first placed into the carton, the rotating shaft 401 is rotated to drive the fixed plate 107 to move upward, thereby driving the rotating frame 11 to move upward, so that the gear 108 meshes with the rack 403. Then, the second air cylinder 404 is driven to extend, thereby driving the rack 403 to move, and then meshing to drive the gear 108 to rotate, thereby driving the rotating frame 11 to rotate 90°. There is an interference fit between the rotating frame 11 and the fixed plate 107 to prevent the rotating frame 11 from rotating. Preferably, a structure locked by a bolt is provided between the rotating frame 11 and the fixed plate 107, and a spring is provided at the structure. After the fixed plate 107 moves upward and contacts the rack 403, the locking mechanism is opened, enabling relative rotation between the two.

[0048] As Figure 11 , to solve the problem of continuously processing by supplementing cartons.

[0049] A material box 15 is fixedly connected to the bracket 14. A push plate 501 is slidably connected inside the material box 15. Two feeding rollers 502 are rotatably connected to the bracket 14. A plurality of positioning rollers 503 are rotatably connected to the bracket 14. A top plate 402 is fixedly connected to the bracket 14.

[0050] Generally, after the carton is processed, it is placed in a parallelogram along the crease. A plurality of cartons are placed in the material box 15. The push plate 501 can push the carton into contact with the feeding roller 502. At this time, the feeding roller 502 is driven to rotate, and then the carton is pushed forward by friction. When the front end of the carton contacts the top plate 402, the carton behind pushes forward, thereby initially opening the carton for the support rod 204 to be inserted. A cross bar is provided on the bracket 14 to support the carton. According to the different lengths of the cartons, the number of rotation circles of the feeding roller 502 each time is set differently, thereby avoiding insufficient pressure of the carton behind on the carton in front and being unable to initially open it, and at the same time avoiding the carton behind moving forward too long and affecting the processing. The two positioning rollers 503 at the front ends on both sides are inclined. Since the carton is folded along the parallelogram crease, when it is opened, the two intersecting positioning rollers 503 can avoid affecting the initial opening of the carton.

[0051] Similarly, a device similar to the material box 15 is provided on the bracket 14, so as to be able to supplement the cardboard between the clamping rods 104.

[0052] As Figure 2 , the periphery of a packaging carton is a traditional corrugated carton, and the arc-shaped corrugated cardboard provided inside can further improve the anti-collision effect on the internal goods and avoid damage to the internal items caused by collision during transportation.

[0053] As Figure 1 , a processing method used by a packaging carton processing device includes the following steps;

[0054] S1: Place the corrugated cardboard box in the bin 15, and then drive the feeding roller 502 to rotate to send the cardboard box to the processing position between the rotating frame 11 and the support disk 12;

[0055] S2: Drive the support disk 12 to move upward, and then simultaneously drive the four first air rods 13 to extend to support the cardboard box;

[0056] S3: Fix the corrugated cardboard between the clamping rods 104, drive the bidirectional air rod 106 to extend, drive the rotating frame 11 to move downward, then drive the bidirectional air rod 106 to reset, and then drive the rotating frame 11 to move upward and reset, so as to set the cardboard inside the cardboard box;

[0057] S4: Drive the second air rod 404 to extend, and then repeat S3.
