Description

Technical Field

[0001] The invention relates to the technical field of packaging box production, and in particular to a full-automatic fastening packaging production system. Background Art

[0002] With the rapid development of e-commerce today, there are hundreds of millions of express parcels every day and a wide variety of products. The outer packaging used for express transportation is also crucial. Currently, there are many defects in the express packaging for small commodities.

[0003] In order to prevent items from being damaged by collision during transportation, express packaging will use bubble columns to wrap goods, or put plastic air bags in the packaging box. Bubble columns and plastic air bags both play a role in shock absorption and impact resistance. However, when packaging personnel use bubble columns to pack items, they need to manually wrap them and use additional transparent glue to fix the bubble columns on the items, which takes a long time. In addition, bubble columns and plastic air bags take up a large space during storage, and the use of bubble columns and plastic air bags leads to a significant increase in the use of plastic. Customers generally discard the items directly after receiving them and regard them as garbage, which is not conducive to environmental protection. In the current related technology, in order to solve the above-mentioned multiple problems at the same time during product transportation, the staff often fixes an elastic film on the packaging box, which is arranged on the top of the packaging box, and two of the opposite sides of the film are respectively fixed to the two opposite sides of the packaging box by a hot pressing process. The space formed when the film is stretched relative to the packaging box can be used to place items. The setting of the film can achieve fastening of the product while relatively reducing the occupied space and can also fit on the surface of the packaging box after use.

[0004] In the existing packaging box production technology, generally the staff will place the prepared packaging boxes on the workbench one by one, and then manually adjust the position of the packaging boxes. After that, the staff will manually cut out a film of a size that matches the plate and cover the surface of the plate. Finally, the staff will operate the hot pressing device to heat the film on the opposite sides of the plate so that the film is fastened to the surface of the plate, completing the processing of the film and the packaging box packaging material. However, the manual assembly method is time-consuming and labor-intensive, and the labor cost is high. Therefore, there is room for improvement. Summary of the invention

DETAILED DESCRIPTION

[0039] The present invention will be further described in detail below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0040] Combination Figure 1 and Figure 2 A fully automatic fastening packaging production system is used to fasten a film to the surface of a plate. The production system includes a positioning and conveying platform A, an automatic unloading system C, a positioning and film placing system B, and a hot-sealing device D. The automatic unloading system C, the positioning and film placing system B, and the hot-sealing device D are all integrated on the positioning and conveying platform A. Specifically, the automatic unloading system C is set up at one end of the positioning and conveying platform A, and the positioning and film placing system B and the hot-sealing device D are set in the middle of the positioning and conveying platform A in an upper and lower position.

[0041] The automatic unloading system C is used to transfer the prepared plates to the surface of the positioning and transmission platform A in sequence. The positioning and transmission platform A is used to intermittently transport the plates from the automatic unloading system C along a predetermined route. The positioning and film placing system B is used to coat the surface of the plates passing directly below. The hot pressing device D is used to hot-press the film covering the plates to the surface of the plates and to cut the film between two adjacent plates.

[0042] In the production process of this production system, the positioning and transmission platform A is always in operation. Initially, the number of plates on the positioning and transmission platform A is zero. After the prepared plates are loaded in the automatic unloading system C, it starts to work and transfers the plates to the positioning and transmission platform A in turn for transportation. When the plates pass under the positioning and film placing system B, the positioning and film placing system B runs, and the surface of the plates is coated with a film. After that, the hot pressing device D works to simultaneously hot-press the continuous film on both sides of the two adjacent plates, and then cut the film between the two plates to obtain independent plates with film on the surface. The processed plates continue to be output by the positioning and transmission platform A.

[0043] Combination Figure 8 and Fig. 9 As a device for placing the plates in advance, the automatic unloading system C includes a fixed frame 100, a plate placing frame 200, and a flip-type negative pressure adsorption device 300. The plate placing frame 200 and the flip-type negative pressure adsorption device 300 are both installed on the fixed frame 100. The entire automatic unloading system C is fixed to one end of the positioning and transmission platform A through the fixed frame 100. When working, the flip-type negative pressure adsorption device 300 adsorbs the plates on the plate placing frame 200, and then flips the adsorbed plates onto the surface of the positioning and transmission platform A, and circulates in sequence to achieve continuous production.

[0044] After the packaging box sheet is manufactured, the sheet placement rack 200 is used to stably stack the manufactured packaging box sheet. Specifically, the sheet placement rack 200 includes a sheet conveyor 210 and a limit assembly 220. The limit assembly 220 cooperates with the sheet conveyor 210 to achieve sequentially fitting the sheets on the sheet conveyor 210. The sheet conveyor 210 is a flat plate structure, fixed on the fixing frame 100, and is arranged in an inclined manner as a whole, and the height of the discharge end of the sheet conveyor 210 is higher than the height of the feed end of the sheet conveyor 210. The limiting assembly 220 includes an upper limiting rod 221, a left limiting rod 222 and a right limiting rod 223 for being set in contact with the plate. The upper limiting rod 221, the left limiting rod 222 and the right limiting rod 223 are arranged in a triangular distribution on the fixing frame 100 and are all located directly above the plate conveying path 210. The upper limiting rod 221, the left limiting rod 222 and the right limiting rod 223 are all arranged parallel to the plate conveying path 210, and the lengths of the three can be consistent with the length of the plate conveying path 210.

[0045] Since the packaging box sheet has four edges, after the sheets stacked in the thickness direction are placed on the sheet conveyor 210, by setting the limiting assembly 220, the upper limiting rod 221, the left limiting rod 222, the right limiting rod 223 and the sheet conveyor 210 cooperate with each other to abut against the four edges of the sheets, thereby playing a limiting role, so that the sheets are stably placed on the sheet conveyor 210. At the same time, the sheet conveyor 210 is inclined, and the stacked sheets are at the discharge end of the sheet conveyor 210 under the action of gravity. In addition, a top pressure plate 211b can be set on the sheet conveyor 210, and the top pressure plate 211b can be set in an L shape to apply an additional pressure to the sheets, so that the sheets are relatively close to each other.

[0046] In order to facilitate installation and removal of the limit assembly 220 on the fixing frame 100, the upper limit rod 221 is connected to the fixing frame 100 in a detachable fixed connection. Specifically, an adjustment rod 224 is protruding from the outer wall of the upper limit rod 221, and the adjustment rod 224 is detachably fixedly connected to the fixing frame 100 by screws. The connection mode of the left limit rod 222, the right limit rod 223 and the fixing frame 100 is the same as the connection mode of the upper limit rod 221 and the fixing frame 100.

[0047] Optimized, as shown in the figure, an intermittently operating auxiliary guide belt 212 is arranged around the plate conveying path 210. When the flip-type negative pressure adsorption device 300 adsorbs the plate on the plate conveying path 210, the auxiliary guide belt 212 simultaneously runs downward, which is equivalent to applying a thrust to the plate, which offsets the clamping force applied by the limit assembly 220 to the plate, so as to facilitate the plates to leave the plate conveying path 210 one by one.

[0048] The flipping negative pressure adsorption device 300 is used to intermittently adsorb the plates at the discharge end of the plate conveyor 210 in sequence and then place them flat on the positioning and transmission platform A. In detail, the flipping negative pressure adsorption device 300 includes a suction cup 310, a first flip cylinder 320, a second flip cylinder 330, a third fixing rod 340 and a second connecting rod 350. Two suction cups 310 are provided, both of which are transmission-connected with the first flip cylinder 320. The first flip cylinder 320 is installed on the fixing frame 100 through the third fixing rod 340. The first flip cylinder 320 is located above the positioning and transmission platform A and is arranged close to the discharge end of the plate conveyor 210. The second connecting rods 350 are provided at both ends of the third fixing rod 340. The second connecting rods 350 are correspondingly transmission-connected with the second flip cylinder 330. The second flip cylinder 330 is installed on the fixing frame 100.

[0049] Under the limiting action of the limiting assembly 220, the prepared packaging box plates are neatly stacked on the plate conveyor 210. When the packaging box plates need to be transferred to the positioning and transmission platform A, the flip-type negative pressure adsorption device 300 works, and the first flip cylinder 320 drives the suction cup 310 to extend and retract. When extended, the suction cup 310 adsorbs the surface of the plate under the action of negative pressure, and then the first flip cylinder 320 flips toward the surface of the positioning and transmission platform A. At the same time, the second flip cylinder 330 extends and flips. Under the transmission action of the second connecting rod 350, the extension direction of the first flip cylinder 320 is set parallel to the vertical direction. Then the first flip cylinder 320 extends again to place the plate on the suction cup 310 on the positioning and transmission platform A, which is convenient for subsequent processes. In summary, the staff only needs to stack the prepared packaging box plates on the plate conveyor 210, which is simple to operate and reduces manpower and labor costs.

[0050] Combination Figure 3 and Figure 4 As a device for conveying plates, the positioning and transmission platform A includes a frame 1, which is a rectangular frame as a whole.

The axis direction of the rotating shaft 12 is the same as the width direction of the frame 1. The two ends of the rotating shaft 12 are rotatably connected to the support plates 11 on both sides. Positioning rollers 13 are arranged on both rotating shafts 12. The axis of the positioning rollers 13 is coaxial with the axis of the corresponding rotating shaft 12.

The conveyor belt 2 is tensioned with the positioning rollers 13. A driving motor 14 is arranged on the support plate 11 on one side of the frame 1. The driving motor 14 is detachably fixed to the support plate 11. The rotating shaft of the driving motor 14 is fixed to the rotating shaft 12 on one side of the length direction of the support plate 11.

[0052] A transverse plate 3 is arranged between the two support plates 11. The transverse plate 3 is in the shape of a rectangular plate as a whole, and the length direction of the transverse plate 3 is the same as the width direction of the frame 1. The transverse plate 3 passes through the conveyor belts 2 in the length direction, and the two ends of the transverse plate 3 in the length direction are respectively fixed to the support plates 11 on both sides, and three transverse plates 3 are arranged at intervals along the length direction of the support plates 11.

During use, screws pass through the angle bracket 32 ​​and are threadedly connected with the support plate 31 and the transverse plate 3. By providing the support plate 31 between the conveyor belts 2, the conveyor belt 2 can improve its load-bearing capacity during the process of conveying the plate.

[0054] A partition 21 is provided on the conveyor belt 2. The partition 21 is in the shape of a rectangular plate as a whole. The length direction of the partition 21 is perpendicular to the conveying direction of the conveyor belt 2. One end of the partition 21 in the width direction is fixed to the conveyor belt 2, and the other end extends to the side away from the conveyor belt 2. A number of partitions 21 are evenly spaced around the conveyor belt 2, and a placement station 22 is formed between any two adjacent partitions 21. When in use, the staff places the plates in the corresponding placement stations 22 in turn.

[0055] A plurality of partitions 21 are provided with avoidance grooves 211 a in the middle of the length direction, and the avoidance grooves 211 a connect two adjacent placement stations 22 , so that the interactivity between the two adjacent placement stations 22 is improved.

[0056] A crossbeam 4 is arranged on the support plate 11. The crossbeam 4 is in the shape of a rectangular rod as a whole and is located on the upper side of the conveyor belt 2. The two ends of the crossbeam 4 in the length direction are located on both sides of the conveyor belt 2 in the width direction and are respectively fixed to the support plates 11 on both sides.

[0057] The cross beam 4 is provided with a deviation correction device 5, which includes a guide bar 51. The guide bar 51 is in the shape of a rectangular parallelepiped as a whole. The length direction of the guide bar 51 is the same as the conveying direction of the conveyor belt 2, and the guide bar 51 and the conveyor belt 2 are arranged at intervals. A pressure strip 52 is provided at one end of the guide bar 51 opposite to the conveying direction of the conveyor belt 2 in the length direction. One end of the pressure strip 52 is integrally formed with the guide bar 51, and the other end extends to a side away from the conveyor belt 2. When in use, the plate enters between the guide bar 51 and the conveyor belt 2 under the guiding action of the pressure strip 52, and then the guide bar 51 passes through the avoidance groove 211a on the partition 21. Through the action of the guide bar 51, one side of the plate is aligned with the partition 21.

[0072] Combination Figures 10 to 12The hot-sealing device D is a device for fastening the film to the plate. When working, the hot-sealing device D can first perform a hot-pressing operation on the plate on the positioning and transmission platform A, and then perform a film cutting operation, and finally obtain an independent plate with a film pressed on the surface. Since the film is made of a material that can be deformed by heat, the hot-pressing operation and the film cutting operation are both completed by heating. In detail, the hot-sealing device D includes a hot-pressing mechanism 400, a temperature control host 500 and a cutting mechanism 600. The temperature control host 500 is a prior art and is used to set a certain temperature for the hot-pressing mechanism 400 and the cutting mechanism 600.

[0073] The hot pressing mechanism 400 includes a mounting frame 410, a first lifting cylinder 420 and a hot pressing section 430. The mounting frame 410 is a U-shaped frame as a whole. One end of the mounting frame 410 is hingedly mounted on the positioning and transmission platform A through an axis rod. The hot pressing section 430 is provided at the downward position of the other end of the mounting frame 410, which is in the middle. A gap is formed between the hot pressing section 430 and the positioning and transmission platform A for the plate to pass through, and the hot pressing mechanism 400 can make intermittent up and down lifting movements relative to the positioning and transmission platform A, thereby driving the hot pressing section 430 to press the plate passing through the gap.

[0074] The specific implementation method of the up and down lifting movement of the hot pressing mechanism 400 is as follows: the mounting frame 410 is provided with an end of the ironing part 430 which is transmission connected to the first lifting cylinder 420. Two first lifting cylinders 420 are provided, both of which are fixedly installed at the lower part of the positioning and transmission platform A. The extension direction thereof is inclined. When the first lifting cylinder 420 moves up and down, it pushes the end of the mounting frame 410 to make an upward and downward flipping movement with the shaft as the rotation center, thereby driving the ironing part 430 to move away from and close to the surface of the positioning and transmission platform A.

[0075] Optimized, the mounting frame 410 is detachably fixedly connected to the ironing part 430, and the ironing part 430 specifically includes a first temperature sensor 431, an electric heating plate 432, and a fixing seat 433. The electric heating plate 432 is fixed on the fixing seat 433, and a plurality of spaced screws 433197 are arranged on the top of the fixing seat 433. The screws 433197 are installed on the mounting frame 410 and then locked with nuts 98513 to achieve fastening. The first temperature sensor 431 is installed on the electric heating plate 432 to monitor the real-time temperature of the electric heating plate 432, and the first temperature sensor 431 is electrically connected to the temperature control host 500.

[0076] The cutting mechanism 600 includes a second lifting cylinder 610 and a cutting part 620, and the cutting mechanism 600 can perform intermittent up and down lifting movements relative to the positioning and transmission platform A. Two second lifting cylinders 610 are provided, both of which are fixed at the lower position of the positioning and transmission platform A, and their extension direction is arranged parallel to the vertical direction. The cutting part 620 specifically includes an electric heating blade 621, a blade fixing block 622 and a second temperature sensor 623. The electric heating blade 621 is arranged on the blade fixing block 622, the second lifting cylinder 610 is transmission-connected to the blade fixing block 622, the second temperature sensor 623 is installed on the electric heating blade 621, and is used to monitor the real-time temperature of the electric heating blade 621, and the second temperature sensor 623 is electrically connected to the temperature control host 500.

[0077] When the second lifting cylinder 610 moves up and down, it pushes the blade fixing block 622 and the electric heating blade 621 to move up and down, thereby achieving movement close to and away from the plate.

[0078] In order to reduce the interval time between the film hot pressing operation and the film cutting operation and improve the work efficiency, the ironing section 430 and the cutting section 620 are arranged in an upper and lower interval. The staff sets the temperature of the ironing section 430 and the cutting section 620 on the temperature control host 500. When the packaging box plate runs on the positioning and transmission platform A, the plate passes under the ironing section 430 from the gap. When the sides of the two adjacent plates are under the ironing section 430 at the same time, the hot pressing mechanism 400 moves downward, driving the electric heating plate 432 on the ironing section 430 to contact the edges of the two adjacent plates at the same time. Under the action of heating and pressure, the electric heating plate 432 presses the film on the surface of the plate. Since the film is a continuous structure, the cutting mechanism 600 then moves upward, driving the cutting section 620 to rise. Under the action of heating, the electric heating plate 432 of the cutting section 620 cuts the film at the position between the two plates, thereby obtaining two independently hot-pressed plates with films.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
