Description

Technical Field

[0001] This utility model relates to the field of woven bag sealing technology, specifically an automatic sewing device for fertilizer woven bags. Background Technology

[0002] Fertilizer woven bags are packaging bags made primarily of plastic through a weaving process. They are mainly used to hold various fertilizers (such as chemical fertilizers, organic fertilizers, compound fertilizers, etc.). The automatic sealing device for fertilizer woven bags is a mechanical device specifically used in the fertilizer packaging field to automatically seal the opening of woven bags filled with fertilizer.

[0003] A search revealed a Chinese utility model patent, CN214613009U, which discloses an automated sewing device for woven bags, relating to the field of woven bag sealing technology. This utility model includes a lower clamping wheel support plate and an upper clamping wheel support plate. The right side wall of the lower clamping wheel support plate is fixedly connected to the lower feeding support plate by bolts, and the left side wall of the lower clamping wheel support plate is fixedly connected to the sewing pad by bolts. A lower embossing mechanism is installed inside the lower clamping wheel support plate. The right side wall of the upper clamping wheel support plate is fixedly connected to the upper feeding support plate by bolts, and the left side wall of the upper clamping wheel support plate is fixedly connected to the sewing carrier plate by bolts. An upper embossing mechanism is installed inside the upper clamping wheel support plate. This utility model utilizes a chain to drive a knurling roller, employing a maintenance-free metal chain to drive a metal roller with an embossed surface. The entire driving part and the part in contact with the woven bag are made of metal, improving the durability of the equipment. The use of an embossing roller that can better tighten the bag improves the tightness of the bag.

[0004] However, the device lacks the ability to adapt to woven bags of different thicknesses. When in use, because the upper and lower clamping rollers are fixed and the spacing between them cannot be adjusted, it may fail to tighten thinner woven bags and damage the surface of thicker woven bags, resulting in a narrow range of applicability of the device.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 As shown, this utility model provides a technical solution: An automatic sewing device for fertilizer woven bags includes a base 1, a drive belt 2 connected to the top edge of the base 1, a vertical plate 3 fixedly connected to the top of the base 1 near its center, and a second vertical plate 4 fixedly connected to the top of the base 1 near the first vertical plate 3. A bidirectional lead screw 5 is rotatably connected to the outer surface of the first vertical plate 3. A sewing plate 6 and a sewing device 7 are respectively sleeved on the outer surfaces of the bidirectional lead screw 5 near its two ends. A bidirectional lead screw 8 is rotatably connected to the bottom of the second vertical plate 4, and a flattening component 9 is sleeved on the outer surface of the bidirectional lead screw 8. In use, a second motor 17 drives the sewing device 7 and the sewing plate 6 to move closer to each other. At the same time, the second motor 17 drives two clamping plates 13 to move closer to each other. The woven bag containing fertilizer is transported to the second vertical plate 4 by the drive belt 2. The first motor 14 drives the rotating shaft 15 to rotate, which in turn drives the moving belt 16 to rotate. Under the simultaneous action of the drive belt 2 and the moving belt 16, the woven bag moves towards the second vertical plate 4. Simultaneously, the woven bag slides between the clamps, achieving a flattening effect. The woven bag continues to move to the upright plate 3. After initial flattening, the woven bag moves between the clamps 24. The sewing device 7 and the sealing plate approach each other, and ultrasonic rolling is used to sew the opening. The distance between the clamps, the moving belt 16, the sewing device 7, and the sewing plate 6 can be adjusted according to the thickness of the woven bag, expanding the applicability of the device. The moving belt 16 is made of soft silicone, which has greater friction with the woven bag, assisting the woven bag to continue moving towards the upright plate 3. The distance between the two moving belts 16 is adjusted by rotating the bidirectional screw, making it easy to adjust according to different woven bag thicknesses. This avoids insufficient flattening due to insufficient clamping force and damage to the woven belt due to excessive clamping force. The sewing plate 6 here is a rectangular flat plate, and the sewing device 7 is an ultrasonic rolling sewing device. The two approach each other to process the woven belt opening. The specific ultrasonic technology is existing technology and will not be explained in detail.

[0017] In this embodiment, preferably, a slide rod 10 is inserted into the side of the seam plate 6 and the seam opening device 7 away from the bidirectional screw 5. The slide rod 10 is fixedly connected to the upright plate 3. The two clamping plates 13 and the two moving belts 16 are close to each other, as are the two clamping plates 24, the seam opening device 7, and the seam plate 6. The rotation of the bidirectional screw provides power, and one side slides on the bidirectional screw, while the other side is supported by the slide rod and slides on the slide rod. The slide rod is located on the side of the upright plate away from the bidirectional screw, so as to smoothly move the moving belt 16, the clamping plates, the seam plate 6, and the seam opening device 7.

[0018] In this embodiment, preferably, the flattening assembly 9 includes a horizontal plate 11. The side of the horizontal plate 11 closest to the second bidirectional lead screw 8 is sleeved on the outer surface of the second bidirectional lead screw 8. A sliding rod 12 is inserted into the side of the horizontal plate 11 away from the second bidirectional lead screw 8. A clamping plate 13 is fixedly connected to the bottom edge of the horizontal plate 11. A motor 14 is fixedly connected to the bottom of the horizontal plate 11 near the second bidirectional lead screw 8. A rotating shaft 15 is fixedly connected to the output shaft of the motor 14. A moving belt 16 is driven to the outer surface of the rotating shaft 15. The output shaft of a motor 17 is fixedly connected to one end of the first bidirectional lead screw 5 and the second bidirectional lead screw 8. The motor 17 is fixedly connected to the upright plate 2. In use, starting the motor 17 drives the sewing device 7 and the sewing plate 6 to move closer to each other. At the same time, the motor 17 drives the two clamping plates 2 13 to move closer to each other. The woven bag containing fertilizer is driven to the upright plate 2 by the transmission belt 2. Motor 14 drives shaft 15 to rotate, which in turn drives moving belt 16 to rotate. Under the simultaneous action of transmission belt 2 and moving belt 16, the woven bag moves towards upright plate 2 4. At the same time, the woven bag slides between the clamps, resulting in a flattening effect. The woven bag continues to move to upright plate 3. After the initial flattening treatment, the woven bag moves between clamps 24. The sewing device 7 and sealing plate come close to each other, and the opening is sewn using ultrasonic rolling. The distance between the clamps and moving belt 16, as well as between the sewing device 7 and the sewing plate 6, can be adjusted according to the thickness of the woven bag, expanding the applicability of the device. Motor 2 17 is only located on one side of the lower surface of the top of the upright plate. Its output shaft is fixedly connected to shaft 15. The shaft 15 on the other side of the moving belt 16 is rotatably connected to the rod at the bottom of the horizontal plate 11. Motor 2 17 drives one shaft 15 to rotate, and then the moving belt 16 drives the other shaft 15 to rotate via transmission belt 2.

[0019] In this embodiment, preferably, a connecting plate 18 is fixedly connected to the outer surfaces of the two horizontal plates 11 that are far apart from each other. A cleaning brush 19 is fixedly connected to the outer surface of the connecting plate 18 near the moving belt 16. A guide frame 20 is fixedly connected to the top of the base 1 near the top of the transmission belt 2. An arc plate 21 is fixedly connected to the top of the base 1 near the top of the guide frame 20. A cleaning brush 22 is fixedly connected to the outer surface of the arc plate 21. In use, as the transmission belt 2 and the moving belt 16 are driven, the cleaning brush 19 and the cleaning brush 22 clean the surfaces of the transmission belt 2 and the moving belt 16. Fertilizer powder or particles on the moving belt 16 fall onto the transmission belt 2, and are then cleaned by the friction of the cleaning brush 22 on the arc plate 21. The powder particles are separated from the transmission belt 2, completing the cleaning. An adsorption block is placed on the top of the base 1 near the top of the arc plate 21, which can electrostatically adsorb fine powder particles and debris. Together with the cleaning brush, it can clean and collect impurities on the transmission belt 2 and the moving belt 16.

[0020] In this embodiment, preferably, a vertical plate 23 is fixedly connected to the top of the horizontal plate 11, and the vertical plate 23 is slidably connected to the second vertical plate 4. In use, the two horizontal plates 11 move closer to each other as the bidirectional lead screw rotates, and slide on the lower surface of the top of the second vertical plate 4. The top of the horizontal plate 11 is provided with a convex slider, and the lower surface of the top of the second vertical plate 4 is provided with a groove, and a slider is slidably connected to the inner wall of the groove, thereby ensuring that the two horizontal plates 11 move closer to each other stably.

[0021] In this embodiment, preferably, clamping plates 24 are fixedly connected to the top of both the seam plate 6 and the seam maker 7. The sides of the two clamping plates 24 that are close to each other are on the same vertical plane as the sides of the seam maker 7 and the seam plate 6 that are close to each other. The sides of the two clamping plates 13 that are close to each other are on the same vertical plane as the sides of the two moving belts 16 that are close to each other. In use, the motor 17 is started to drive the seam maker 7 and the seam plate 6 to move closer to each other. At the same time, the motor 17 drives the two clamping plates 13 to move closer to each other. The woven bag containing fertilizer is transported to the upright plate 4 by the transmission belt 2. The motor 14 is started to drive the rotating shaft 15 to rotate, which drives the moving belt 16 to rotate. Under the simultaneous action of the transmission belt 2 and the moving belt 16, the woven bag moves towards the upright plate 4. As the woven bag slides between the clamps, it achieves a flattening effect. The woven bag continues to move to the upright plate 3. After the initial flattening treatment, the woven bag moves between the clamps 24. The sewing device 7 and the sealing plate approach each other, and the opening is sewn using ultrasonic rolling. The distance between the clamps, the moving belt 16, the sewing device 7, and the sewing plate 6 can be adjusted according to the thickness of the woven bag, expanding the applicability of the device. Among them, the side of the two clamps 24 that are close to each other is on the same vertical plane as the side of the sewing device 7 and the sewing plate 6 that are close to each other. The side of the two clamps 13 that are close to each other is on the same vertical plane as the side of the two moving belts 16 that are close to each other. The woven belt can be flattened and moved at the same time, and the woven belt that is about to be sewn is flattened in preparation.

[0022] Working principle: In this embodiment, the automatic sewing device for fertilizer woven bags is started when motor 17 drives the sewing device 7 and the sewing plate 6 to move closer to each other. At the same time, motor 17 drives the two clamping plates 13 to move closer to each other. The woven bag containing fertilizer is transported to the upright plate 4 by the transmission belt 2. Motor 14 drives the rotating shaft 15 to rotate, which in turn drives the moving belt 16 to rotate. Under the simultaneous action of the transmission belt 2 and the moving belt 16, the woven bag moves towards the upright plate 4. At the same time, the woven bag slides between the clamping plates, resulting in a flattening effect. The woven bag continues to move to the upright plate 3. After the initial flattening treatment, the woven bag moves between the clamping plates 24. The sewing device 7 and the sealing plate move closer to each other, and the opening is sewn using ultrasonic rolling. The distance between the clamping plates and the moving belt 16, as well as the distance between the sewing device 7 and the sewing plate 6, can be adjusted according to the thickness of the woven bag, thus expanding the applicability of the device.
