Description

Technical Field

[0001] The utility model relates to the technical field of paper bag processing, in particular to an auxiliary positioning device for pasting the bottom of a paper bag. Background Art

[0002] Auxiliary positioning of paper bag bottom gluing refers to the use of various tools and techniques to assist in positioning and alignment during the production process of the paper bag bottom to ensure the accuracy and stability of the folding, bonding and final structure of the bottom. In the existing technology, the paper bag is fixed by fixing the mold and other devices, but the fixing device will occupy the position during the paper bag processing, which will have an adverse effect on the processing efficiency of the paper bag. In addition, when there is dust and impurities on the paper bag, these foreign matter will interfere with the effective bonding of the glue or adhesive, resulting in a weak bond.

The two stoppers cooperate to position the paper bag.

[0004] However, the existing technology is unable to clean the dust and impurities attached to the surface of the paper bag, which may easily lead to the paper bag being loosely adhered, thereby affecting the quality of the paper bag. In addition, the existing technology is unable to effectively fix the middle part of the paper bag, which may easily lead to dislocation and deformation of the paper bag when the bottom is pasted. The existing technology uses a mold to fix the paper bag, which occupies the position during the processing of the paper bag, making it inconvenient to process the paper bag and affecting the processing efficiency.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 7 As shown, an auxiliary positioning device for pasting the bottom of a paper bag includes an auxiliary part 1 and a positioning part 2. The positioning part 2 includes a positioning internal frame 203 fixedly arranged on a positioning external frame 201. A plurality of positioning plates 202 for positioning are connected by ball joints on the inner wall of the positioning internal frame 203. An auxiliary double-headed motor 114 is fixedly arranged on the positioning external frame 201. Auxiliary fan blades 117 are fixedly arranged at one end of the auxiliary double-headed motor 114. The auxiliary fan blades 117 are rotatably arranged in an auxiliary exhaust shell 113. The auxiliary exhaust shell 113 is connected to the auxiliary exhaust box 110 through an exhaust pipe, and the exhaust pipe is a rubber hose; an air inlet is provided on the auxiliary exhaust shell 113; an auxiliary exhaust head 111 is provided on the auxiliary exhaust box 110, and an auxiliary head spring 112 is provided between the auxiliary exhaust head 111 and the auxiliary exhaust box 110.

[0022] like Figures 1 to 7As shown, the other end of the auxiliary double-headed motor 114 is fixedly provided with an auxiliary connecting rod 115, and the auxiliary connecting rod 2 116 is rotatably provided on the auxiliary connecting rod 115. The other end of the auxiliary connecting rod 2 116 is rotatably provided on the auxiliary upper bracket 109, and the auxiliary upper bracket 109 is slidably provided on the positioning external frame 201 through a guide column; the auxiliary upper bracket 109 is provided with a groove that slides with the auxiliary clamping claw 2 107 and the auxiliary clamping claw 1 105, and an auxiliary spring 108 is fixedly provided between the auxiliary clamping claw 2 107 and the auxiliary clamping claw 1 105, the auxiliary clamping claw 2 107 and the auxiliary clamping claw 1 105 are rotatably provided on the auxiliary lower bracket 106, and the auxiliary lower bracket 106 is slidably provided on the guide column, and the auxiliary clamping claw 2 107 and the auxiliary clamping claw 1 105 are transmitted through the auxiliary connecting rod 3 118.

[0023] like Figures 1 to 7 As shown, the auxiliary claw 105 slides with the auxiliary sliding frame 103 slidingly set on the auxiliary fixed shell 104; the auxiliary sliding frame 103 slides with the auxiliary cam 102 rotatably set on the auxiliary fixed shell 104, and the auxiliary cam 102 is fixedly set with an auxiliary handle 101; the auxiliary exhaust head 111 and the auxiliary exhaust box 110 are hollow structures, and the auxiliary exhaust box 110 is fixedly set on the auxiliary lower bracket 106; the outer layer of the auxiliary handle 101 is provided with a rubber layer, and the auxiliary handle 101 is provided with an anti-slip groove; the outer layer of the positioning plate 202 is provided with a rubber layer.

[0024] like Figures 1 to 7 As shown, the utility model discloses an auxiliary positioning device for pasting the bottom of a paper bag, whose working principle is as follows: the paper bag to be processed is sent in from the positioning internal frame 203, and the angle and direction of the positioning plate 202 are manually adjusted so that the paper bag to be processed is positioned by the positioning plate 202, that is, the paper bag is restricted on all sides by the positioning plate 202 on the positioning internal frame 203; at the same time, the auxiliary double-headed motor 114 is turned on, and the auxiliary double-headed motor 114 rotates and drives the auxiliary connecting rod 115 and the auxiliary fan blade 117 to rotate. When the auxiliary fan blade 117 rotates, air is sucked in from the air inlet on the auxiliary exhaust shell 113, and the air is transported to the auxiliary exhaust box 110 through the exhaust pipe, and finally sprayed out by multiple auxiliary exhaust heads 111 to spray the paper bag on the positioning internal frame 203. The air sprayed by the auxiliary exhaust head 111 fixes the middle part of the paper bag on the positioning internal frame 203, so that the middle part of the paper bag is tightly fitted with the positioning internal frame 203, which is convenient for the subsequent bottom pasting work.

[0025] When there is dust or other impurities on the paper bag to be processed, the operator manually pushes the auxiliary handle 101 to rotate, and the rotation of the auxiliary handle 101 drives the auxiliary cam 102 to rotate. When the auxiliary cam 102 rotates, it pushes the auxiliary sliding frame 103 to make the auxiliary sliding frame 103 slide. When the auxiliary sliding frame 103 slides, it disengages from the auxiliary claw 105. Under the action of the auxiliary spring 108, the auxiliary claw 105 is engaged with the groove on the auxiliary upper bracket 109. At this time, the auxiliary connecting rod 115 rotates to drive the auxiliary Auxiliary connecting rod 2 116 enables the auxiliary upper bracket 109 to slide on the positioning external frame 201. The auxiliary upper bracket 109 slides through the auxiliary claw 105 to drive the auxiliary lower bracket 106, the auxiliary exhaust box 110, and the auxiliary exhaust head 111 to slide back and forth. When the auxiliary exhaust head 111 slides back and forth, the distance between the auxiliary exhaust head 111 and the paper bag changes. At the same time, the air ejected by the auxiliary exhaust head 111 cleans the paper bag on the positioning internal frame 203 to prevent dust or impurities from affecting subsequent processing.

[0026] After the impurities on the paper bag are cleaned, the operator manually resets the auxiliary cam 102 through the auxiliary handle 101, so that the auxiliary sliding frame 103 pushes the auxiliary claw 105. At this time, the auxiliary claw 105 is out of contact with the groove on the auxiliary upper bracket 109. At this time, the auxiliary lower bracket 106, the auxiliary exhaust box 110, and the auxiliary exhaust head 111 are in a fixed position and no longer slide back and forth.
