Description

Technical Field

[0001] The utility model relates to the technical field of paper-plastic bag slitting and bag making, and particularly relates to a paper-plastic bag slitting and bag making device. Background Art

[0002] When paper-plastic bags are processed and produced, the cut semi-finished paper-plastic bags will enter the printing equipment, and one side or both sides of the semi-finished paper-plastic bags are printed by the printing equipment. After printing, they are then passed through a cutting and heat fusion device. At this time, the semi-finished paper-plastic bags are heat-fused into three-sided sealed paper-plastic bags by the cutting and heat fusion device. At the same time of heat fusion, a cutting knife is used to cut them, thus completing the three-sided sealing and cutting of the paper-plastic bags.

[0003] Since the cutting and heat fusion device uses the opposite rotation of two groups of rollers, when the semi-finished paper-plastic bags pass between the two groups of rollers, at this time, the heat fusion plate on the rollers can be used to seal the paper-plastic bags first. At the same time of sealing, the cutting knife on the rollers is used to cut the connection between the previous paper-plastic bag and the next paper-plastic bag, thus completing the production of the paper-plastic bags. Although this production method is relatively fast, the contact time between the heat fusion plate on the conveying rollers and the paper-plastic bags is short, and it is easy to have insufficient heat fusion, resulting in insufficient sealing firmness of the paper-plastic bags, thereby reducing the yield.

[0007] Furthermore, the conveying and pressing-down assembly includes a long board. One end of the bent rod is fixedly connected to the long board. The top surface of the long board is fixedly connected to a long rod. One side of the long rod is rotatably connected to a rocker through a pin shaft.

[0012] Furthermore, the storage assembly further includes a bidirectional pneumatic rod and a stacking groove. Stacking grooves are respectively arranged at both ends of the storage plate. The bidirectional pneumatic rod is fixedly connected to the bottom surface of the storage plate. Opposing frames are respectively fixedly connected to the output ends of the bidirectional pneumatic rod.

[0013] The utility model provides a paper-plastic bag slitting and bag-making device. Compared with the prior art, the following beneficial effects are achieved:

As the thickness of the paper and plastic tape increases, the storage plate is driven down by the lifting pneumatic rod to store more paper and plastic tapes. After a certain amount of paper and plastic tapes are stored, the two-way pneumatic rod is used to drive the opposite frame to move. At this time, the opposite frame can be used to limit the two ends of the paper and plastic bags, so that the paper and plastic bags are neatly stacked, which is convenient for the staff to take and store them later.

[0028] Example 1

[0029] In order to solve the technical problems in the background technology, a paper-plastic bag cutting and making device is provided as follows:

[0030] Combine Figures 1 - 7 As shown, the utility model provides a paper-plastic bag cutting and bag-making device, which includes a mounting plate 1; a limiting component 2 is installed on the top surface of the mounting plate 1, and a bending rod 3 is fixedly connected to the top surface of the mounting plate 1 and located on one side of the limiting component 2, and a conveying pressing component 4 is installed at one end of the bending rod 3, and a supporting rod 5 is fixedly connected to the top surface of the mounting plate 1 and located on one side of the bending rod 3. A cutting component 6 is installed at one end of the supporting rod 5, and the cutting component 6 is located above the limiting component 2, and a storing component 7 is installed on the top surface of the mounting plate 1 and located at one end of the limiting component 2; the limiting component 2 includes a conveying platform 21, and the top surface of the mounting plate 1 is fixedly connected to the conveying platform 21, and the top surface of the conveying platform 21 is provided with a dovetail groove 22, and the inside of the dovetail groove 22 is rotatably connected to a bidirectional threaded rod 23, and the two ends of the outer surface of the bidirectional threaded rod 23 are respectively threadedly connected to a dovetail block 24, and the dovetail block 24 slides in the dovetail groove 22, and the top surface of the dovetail block 24 is rotatably connected to a limiting wheel 25.

[0031] The two sets of dovetail blocks 24 are driven to move in opposite directions by the bidirectional threaded rod 23 , so that the two sets of limiting wheels 25 are moved closer to or farther away from each other. At this time, the two sets of limiting wheels 25 can be used to limit paper-plastic bags of different widths.

[0032] In this embodiment, the conveying and pressing assembly 4 includes a long plate 41, one end of the bending rod 3 is fixedly connected to the long plate 41, the top surface of the long plate 41 is fixedly connected to the long rod 42, and one side of the long rod 42 is rotatably connected to the tilting rod 43 through a pin shaft, and the two ends of the long plate 41 and the two ends of the tilting rod 43 are respectively installed with a conveying component 44 and a pressing component 45, the conveying component 44 includes a lifting pneumatic rod 441, the top surface of the long plate 41 is fixedly connected to the lifting pneumatic rod 441, the output end of the lifting pneumatic rod 441 is fixedly connected to the lifting rod 442, and one end of the lifting rod 442 is fixedly connected to the conveyor belt 443, and the pressing component 45 includes a pressing rod 451, the long plate 41 is slidingly connected to the pressing rod 451, the bottom surface of the pressing rod 451 is fixedly connected to the pressing plate 452, and one side of the pressing rod 451 and located between the top surfaces of the long plate 41 is fixedly connected with a telescopic damping rod 453.

[0033] By raising the pneumatic rod 441 to drive the conveyor belt 443 to move upward, the conveyor belt 443 can be moved away from the paper-plastic bag and will no longer convey the paper-plastic bag. At the same time, the raising rod 442 will raise one end of the tilting rod 43, so that the other end of the tilting rod 43 will press the lower pressure rod 451 and the lower pressure plate 452 downward. At this time, the lower pressure plate 452 can cooperate with the conveying platform 21 to clamp the paper-plastic bag, which is convenient for later cutting. When the pneumatic rod 441 is raised to drive the conveyor belt 443 to move downward, the paper-plastic bag can be conveyed, and the lower pressure plate 452 will no longer clamp and fix the paper-plastic bag.

[0034] Embodiment 2

[0035] like Figures 1 - 7 As shown, based on the above embodiment, this embodiment further provides the following content:

[0036] The cutting assembly 6 includes a cutting pneumatic rod 61, the bottom surface of the support rod 5 is fixedly connected to the cutting pneumatic rod 61, the output end of the cutting pneumatic rod 61 is fixedly connected to a rectangular plate 62, the bottom surface of the rectangular plate 62 is respectively fixedly connected to a reset damping rod 63 and a cutting knife 64, and one end of the reset damping rod 63 is fixedly connected to a hot pressing plate 65.

[0037] The pneumatic rod 61 is cut to drive the hot pressing plate 65 and the cutting knife 64 to move downward. As the hot pressing plate 65 moves downward, the conveying platform 21 can be used to seal the next paper-plastic bag, so that the three sides of the paper-plastic bag are sealed. At the same time, the cutting knife 64 cuts off the previous paper-plastic bag that has been sealed on three sides.

[0038] Embodiment 3

[0039] As Figures 1 - 7 shown, on the basis of the above embodiments, the following content is further given in this embodiment:

[0040] The storage assembly 7 includes a lifting pneumatic rod 71. The top surface of the mounting plate 1 is fixedly connected with the lifting pneumatic rod 71. The output end of the lifting pneumatic rod 71 is fixedly connected with a storage plate 72. A displacement groove 73 is arranged on the top surface of the storage plate 72. A displacement threaded rod 74 is rotatably connected in the displacement groove 73. A blocking frame 75 is threadedly connected to the outer surface of the displacement threaded rod 74. The storage assembly 7 further includes a two-way pneumatic rod 76 and a stacking groove 77. Stacking grooves 77 are respectively arranged at both ends of the storage plate 72. The bottom surface of the storage plate 72 is fixedly connected with a two-way pneumatic rod 76. The output ends of the two-way pneumatic rod 76 are respectively fixedly connected with an opposing frame 78.

[0041] By cooperating the displacement threaded rod 74 with the blocking frame 75, the blocking of plastic bags of different lengths can be realized, and the blocked plastic bags are located on the storage plate 72. When the thickness of the plastic tape increases, at this time, the storage plate 72 is driven to descend by the lifting pneumatic rod 71, so that more plastic tapes can be stored. After storing a certain number, the opposing frame 78 is driven to move by the two-way pneumatic rod 76. At this time, the two ends of the plastic bag can be limited by the opposing frame 78, so that the plastic bags are neatly stacked, which is convenient for the later staff to take and store.

[0042] The working principle and usage process of the present utility model:

[0043] In the usage state:

[0044] During use, first, place the plastic bag with both sides sealed and printed on the conveying rack. At this time, pass one end of the plastic bag through between the conveying component 44, the limiting component 2, the pressing component 45 and the cutting component 6. Then, rotate the two-way threaded rod 23. As the two-way threaded rod 23 rotates, it will drive the two dovetail blocks 24 to move towards each other. As the dovetail blocks 24 move, the limiting wheels 25 will be driven to move, so that the two ends of the plastic bag are limited by the two limiting wheels 25;

[0045] After limiting, at this time, adjust the blocking frame 75 according to the required cutting length. Then, rotate the displacement threaded rod 74. As the displacement threaded rod 74 rotates, it will drive the blocking frame 75 to move, so as to adjust the distance between the blocking frame 75 and the end face of the conveying table 21, so as to cut plastic bags of different lengths later;

[0046] Before cutting, first, start the lifting pneumatic rod 441. As the pneumatic rod 441 works, it will drive the lifting rod 442 to move downward. At this time, the lower pressure rod 451 will drive the lower pressure plate 452 to move upward under the action of the telescopic damping rod 453. As the lower pressure plate 452 moves upward, it will no longer clamp the paper and plastic bag. At this time, the conveyor belt 443 can convey the paper and plastic belt forward until one end of the paper and plastic bag contacts one side of the blocking frame 75. After contact, the lifting pneumatic rod 441 is started again to make the conveyor belt 443 away from the paper and plastic bag. At the same time, the upward movement of the lifting rod 442 will cause one end of the tilting rod 43 to press the lower pressure rod 451, which will drive the lower pressure plate 452 to move downward, clamping the paper and plastic bag between the lower pressure plate 452 and the conveying platform 21.

[0047] When cutting begins, the cutting pneumatic rod 61 is activated. As the cutting pneumatic rod 61 works, the rectangular plate 62 is driven to move downward. As the rectangular plate 62 moves downward, the reset damping rod 63, the cutting knife 64 and the hot pressing plate 65 are driven to move downward. At this time, the hot pressing plate 65 will first contact the paper-plastic bag and perform heat-melt sealing on the next paper-plastic bag to be cut. At this time, the cutting pneumatic rod 61 works again, which will drive the cutting knife 64 to move downward, and the paper-plastic bag with the previous heat-melt seal can be cut, so that the paper-plastic bag sealed on three sides falls on the storage plate 72.

[0048] As the number of paper and plastic bags on the storage plate 72 increases, the lifting pneumatic rod 71 will drive the storage plate 72 to move downward, so that the storage plate 72 can accommodate more paper and plastic bags. When a certain number of paper and plastic bags are stored, the two sets of opposing frames 78 will move toward each other through the bidirectional pneumatic rod 76, so that the paper and plastic bags can be neatly stacked, making it convenient for later personnel to take out and store them.
