Description

Technical Field

[0001] The present invention relates to the technical field of bag production, and in particular to a bag positioning device for bag production. Background Art

[0002] Bags are daily necessities made of cloth as the main body and sewn together to carry items. By folding and sewing the cloth to form a cavity inside, items can be easily loaded and taken out through the cavity.

[0003] During the production process of bags, in order to make the inner cavity size of each bag consistent and avoid the unprocessed bags from being stacked together, a bag positioning device is needed to position the bags. The bag positioning device can also fix the bags from the inside out, which makes it more convenient for workers to sew and connect each part of the bags and avoid the phenomenon of mutual extrusion and deformation of the bags during the production process, so that the bags can be processed in an orderly manner and output one by one for collection after processing. After the bags that have not been sewn are placed on the bag positioning device, the inside of the bags is expanded through the external expansion device thereon to be fixed and positioned, and the bags are transported to the sewing device through the bag positioning device for automatic or manual sewing. After the finished bags are formed, they are sent out one by one from the end of the bag positioning device in order and collected manually, so that the size of the inner cavity of the bags can be kept consistent, and the quality stability of the bags is better. At the same time, there will be no phenomenon of multiple unprocessed bags being stacked together, which effectively improves the processing efficiency of the bags.

[0004] Although the above-mentioned existing technology can solve the corresponding technical problems, it still has certain defects: when the existing luggage positioning device is used to position a luggage with a smooth soft leather inner surface, the luggage positioning device fixes the luggage and expands the inner cavity of the luggage through the external expansion pressure of the external expansion device, and the position in contact with the external expansion device will be squeezed by a large pressure, which can easily cause extrusion dents on the inner surface of the luggage in contact with the external expansion position, requiring additional processes for restoration. At the same time, if the pressure of the external expansion device is high, it may even cause pressure damage on the inner surface of the luggage, thereby increasing the scrap rate of luggage production.

An exhaust pipe 56 is provided on the other side of the through-tube 51, and the exhaust pipe 56 comprises an exhaust pipe body 561 arranged on the other side of the through-tube 51 and a middle block 562 arranged at the center of the inner cavity of the exhaust pipe body 561. The cross-sectional width of one side of the middle block 562 close to the through-tube 51 is greater than that of the other side of the middle block 562. A sliding piece 563 is provided between the inner wall of the through-tube 51 and the middle block 562 to close the inner wall of the through-tube 51 and the wider side of the middle block 562. A fixing block 564 is provided at the end of the exhaust pipe body 561, and a return spring 565 is provided between the fixing block 564 and the sliding piece 563. A deformation piece 52 connected to the base plate 491 is provided on the other side of the penetration tube 51, and one end of the flexible fixing block 494 is fixedly connected to the surface of the base plate 491. The unprocessed luggage is placed in the storage bin 41 and the inflation tube 45 is inflated, so that the air pressure pushes out the piston column 48 so that it pushes the flexible outward push plate 49 to cooperate with the inner wall of the storage bin 41 to position and fix the unprocessed luggage. When in use, the unprocessed luggage is placed in the storage bin 41, and the inflation tube 45 is externally inflated, so that the high-pressure gas enters the inflation tube 45 through the air inlet channel 46, and then is introduced into the air pressure tube 47 through the air inlet channel 46, and the piston column 48 is pushed outward by the air pressure tube 47, so that the piston column 48 pushes the flexible outward push plate 49 to move toward the inner wall of the storage bin 41.Then, the loaded unprocessed bag is squeezed so that it is clamped and fixed by the flexible push-out plate 49 cooperating with the inner wall of the accommodating chamber 41. When the flexible push-out plate 49 squeezes the inner wall of the bag, the contact plate 492 first contacts the inner wall of the bag, so that the flexible fixing block 494 contacts the inner wall of the bag synchronously, so that the flexible fixing block 494 and the contact plate 492 are squeezed at the same time, and the excessive pressure generated is absorbed by the deformation sheet 52 of the flexible fixing block 494, so that the pressure applied to the inner wall of the bag is absorbed and released slowly, and the squeezing will cause the pressing sheet 54 of the flexible fixing block 494 to be squeezed and deformed. The air inside is then pressed out through the buffer adsorption tube 53. When the air enters the buffer adsorption tube 53, it first needs to push the swinging sealing piece 533 of the horizontal piece 532 up and down to squeeze the elastic piece 535 and make its two ends lose contact with the adsorption tube body 531, so that the air can pass through the adsorption tube body 531 at a certain speed, and then a certain support effect is generated through the air, which again buffers the extrusion force on part of the luggage. At the same time, after the air passes through, it is squeezed out from the exhaust pipe 56, and the air pressure pushes the sliding piece 563 between the exhaust pipe body 561 and the middle block 562 to make it fit the exhaust pipe body 561. The slide 563 on the inner wall of the tube body 561 slides. Since the cross-sectional width of the middle block 562 on one side close to the penetration tube 51 is greater than that on the other side of the middle block 562, when the slide 563 slides, a gap is generated between it and the middle block 562, thereby allowing the air to be discharged and squeezing the return spring 565 at the same time, thereby causing the return spring 565 to generate elastic force. After the air is discharged, the return spring 565 pushes the slide 563 back to reset, so that the gap between the exhaust tube body 561 and the middle block 562 is reclosed, thereby causing the open end of the buffer adsorption tube 53 of the flexible fixed block 494 to close due to the internal and external pressure difference. Suction is generated, and the pressing sheet 54 and the buffer adsorption tube 53 are simultaneously attached to the inner surface of the bag, thereby adsorbing and fixing the inner surface of the bag through suction, and the deformable pressing sheet 54 and the deformable sheet 52 fully absorb the pressure generated by the contact plate 492. At the same time, the piston column 48 is pushed by air pressure to move the piston column 48, and the air is compressible. Therefore, when the pressure is too high, the pressure can be further prevented from being excessively applied to the inner wall of the bag through the compression and contraction of the air, and the inner wall of the bag will not be squeezed and damaged due to excessive pressure. The fixing effect is good and the scrap rate is reduced;

[0022] A pressure plate 42 is provided on the inner wall of the storage bin 41, and a plurality of hollow hemispherical elastic blocks 43 are provided between the pressure plate 42 and the inner wall of the storage bin 41. In this embodiment, seven of them are provided, which is conducive to further absorbing excessive external expansion pressure by moving the pressure plate 42 toward the inner wall of the storage bin 41 to squeeze the elastic blocks 43, thereby better protecting the luggage from being squeezed and damaged, and ensuring its integrity;

[0023] An airbag tube 44 is provided on one side of the pressure plate 42 away from the inner wall of the receiving chamber 41, which is conducive to absorbing pressure through deformation of the airbag tube 44, and buffering the pressure on the outer surface of the bag with its relatively soft outer surface, thereby further ensuring the integrity of the bag;

[0024] A buffer airbag 495 is also provided on the contact surface of the contact plate 492, which is conducive to further absorbing the pressure exerted by the contact plate 492 on the inner surface of the bag through the buffer airbag 495;

[0025] The end of the swing sealing piece 533 that is attached to the adsorption tube body 531 is provided with a silicone block 534, which is beneficial to improve the attachment effect between the swing sealing piece 533 and the inner wall of the adsorption tube body 531;

[0026] An arc-shaped groove is provided on the surface of one side of the sliding piece 563 close to the penetration tube 51, which is beneficial to expand the contact area with the air, thereby allowing the sliding piece 563 to slide more efficiently.

[0027] Working principle of the present invention: When the present invention is used, the unprocessed luggage is placed in the storage bin 41, and the inflation tube 45 is externally inflated, so that the high-pressure gas enters the inflation tube 45 through the air inlet channel 46, and then is introduced into the air pressure tube 47 through the air inlet channel 46, and the piston column 48 is pushed outward through the air pressure tube 47, so that the piston column 48 pushes the flexible outward push plate 49 to move toward the inner wall of the storage bin 41, and then the loaded unprocessed luggage is squeezed so that it is clamped and fixed by the flexible outward push plate 49 and the inner wall of the storage bin 41. When the flexible outward push plate 49 squeezes the inner wall of the luggage, the contact plate 492 first contacts the inner wall of the luggage, so that the flexible fixing block 494 contacts the luggage synchronously. The inner wall of the bag is squeezed so that the flexible fixing block 494 and the contact plate 492 are squeezed at the same time, and the excessive pressure generated is absorbed by the deformation sheet 52 of the flexible fixing block 494, thereby absorbing and slowly releasing the pressure applied to the inner wall of the bag. At the same time, the squeezing will cause the pressing sheet 54 of the flexible fixing block 494 to be squeezed and deformed, thereby squeezing the air inside through the buffer adsorption tube 53. When the air enters the buffer adsorption tube 53, it is first necessary to push the swing closing sheet 533 of the horizontal sheet 532 up and down to squeeze the elastic sheet 535 and make its two ends lose the fit with the adsorption tube body 531, so that the air can pass through the adsorption tube body 531 at a certain speed, thereby generating a certain support through the air. The air is supported and the extrusion force on the bag is buffered again. At the same time, after the air passes through, it is squeezed out of the exhaust pipe 56. The air pressure pushes the sliding piece 563 between the exhaust pipe body 561 and the middle block 562, so that the sliding piece 563 that is attached to the inner wall of the exhaust pipe body 561 slides. Since the cross-sectional width of the middle block 562 on one side close to the penetration pipe 51 is greater than that on the other side of the middle block 562, when the sliding piece 563 slides, a gap is generated between it and the middle block 562, so that the air is discharged, and the return spring 565 is squeezed at the same time, so that the return spring 565 generates elastic force. After the air is discharged, the elastic force of the return spring 565 pushes the sliding piece 563 back to reset, so that it closes the exhaust pipe body 561 and the middle block 562 again. The gap between them makes the open end of the buffer adsorption tube 53 of the flexible fixing block 494 generate suction due to the internal and external air pressure difference, and the pressing sheet 54 and the buffer adsorption tube 53 are simultaneously attached to the inner surface of the bag, thereby adsorbing and fixing the inner surface of the bag by suction, and cooperating with the deformable pressing sheet 54 and the deformable sheet 52 to fully absorb the pressure generated by the contact plate 492. At the same time, the piston column 48 is pushed by the air pressure to move the piston column 48, and the air is compressible. Therefore, when the pressure is too high, the compression and contraction of the air can further prevent excessive pressure from being applied to the inner wall of the bag, and no excessive pressure will be generated to cause the inner wall of the bag to be squeezed and damaged, so the fixing effect is good and the scrap rate is reduced.
