Description

Technical Field

[0001] This invention relates to the field of packaging facilities, specifically to a fabric roll bag device. Background Technology

[0002] Fabric rolls, as a common form of fabric collection, transportation, and storage, usually need to be packaged into woven bags after processing. This step is crucial for subsequent circulation processes. Semi-automatic bagging devices are frequently used in the market to successfully pack fabric rolls into woven bags. These devices are mostly used by manufacturers with smaller production scales and limited workshop space.

[0003] In actual use, existing semi-automatic bagging equipment requires workers to first manually open the opening of the woven bag, and then carefully place the bag opening onto the bag-opening mechanism of the bagging device. During this process, the worker must hold the bag opening and wait for the bag-opening mechanism to start and fully open and expand the woven bag opening into a circle before the worker can release their hand. This operation process increases the labor intensity of workers, as repetitive actions over a long period of time can easily lead to fatigue and increase the likelihood of operational errors, resulting in inconvenience in use. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a fabric roll-up bag device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fabric roll-up bag device, comprising a support platform, a first platform plate fixedly installed on one side of the upper end of the support platform, positioning strips embedded at both the front and rear edges of the first platform plate, a vertical groove frame fixedly installed at the upper edge of the rear positioning strip, a lifting tube frame slidably installed through the interior of the vertical groove frame, an air pipe fixedly installed at the end of the lifting tube frame, a suction nozzle installed at the lower end of the air pipe, a fixed seat slidably installed at the end of the first platform plate, and H-shaped frames slidably installed at both ends of the fixed seat. Each of the two H-shaped frames has an upper bag-holding disc fixedly mounted on its opposite ends. A pusher frame is elastically mounted on the side of the fixed base. A bag-holding frame is connected between the pusher frame and the H-shaped frame. A lower bag-holding disc is provided below the two upper bag-holding discs. The lower bag-holding disc is elastically connected to the fixed base. A pressure seat is connected to the lower end of the lower bag-holding disc. A pusher rail is fixedly mounted in the middle of the lower end of the pusher frame. The end of the pusher rail is raised. A pressure roller is rotatably mounted in the middle of the pressure seat. The end of the pusher rail presses against the pressure roller. A pusher is provided on the other side of the upper end of the support.

[0006] Preferably, a second servo push cylinder is fixedly installed at the rear end of the positioning plate strip. The telescopic end of the second servo push cylinder is fixed to the lifting tube frame. Two sliding seats are symmetrically fixedly installed on the inner side of the fixed seat. The two sliding seats are slidably installed at the front and rear edges of the first platform, respectively. The sliding seats are located on the side of the positioning plate strip.

[0007] Preferably, a frame guide seat is slidably mounted on the outer surface of the H-shaped frame, the side of the frame guide seat is fixed to the fixed seat, two guide rods are symmetrically fixed at the lower edge of the side of the fixed seat, the push frame is slidably mounted on the outer surface of the guide rods, a support spring is wound around the outside of the guide rods, one end of the support spring is fixed to the fixed seat, and the other end of the support spring is fixed to the push frame.

[0008] Preferably, a pressing disc is provided on opposite sides of the two upper bag discs. A guide prism is fixedly installed in the middle of the pressing disc. A guide head is slidably installed on the outer surface of the guide prism. The end of the guide head is fixed to the fixed base. A pressing spring is wound around the outside of the guide head and the guide prism. One end of the pressing spring is fixed to the pressing disc, and the other end of the pressing spring is fixed to the stepped surface of the guide head.

[0009] Preferably, two seat rods are symmetrically fixedly installed at the lower end of the lower bag disc. The lower end of the seat rod is fixed to the pressure seat. An extension ear is slidably installed on the outer surface of the seat rod. The end of the extension ear is fixed to the fixed seat. A return spring is wound around the outside of the seat rod. One end of the return spring is fixed to the lower end of the lower bag disc, and the other end of the return spring is fixed to the upper end of the extension ear. A positioning cap is coaxially embedded on the outer surface of the seat rod. The positioning cap fits against the lower end of the extension ear.

[0010] Preferably, a second connector is rotatably mounted on one end of the bag frame, and the end of the second connector is fixed to the end of the push frame. A first connector is rotatably mounted on the other end of the bag frame, and the end of the first connector is fixed to the end of the H-shaped frame.

[0011] Preferably, the pusher includes a second platform fixedly installed on the other side of the upper end of the support. A roll support seat is fixedly installed in the middle of the upper end of the second platform. A servo slide is fixedly installed at the front edge of the upper end of the second platform. A pusher frame is fixedly installed on the upper end of the servo slide. Multiple pusher claws are fixedly installed in a circular array at the end of the pusher frame.

[0012] Preferably, a servo push cylinder is fixedly installed at the lower end of the second platform, and the output end of the servo push cylinder is fixed to the push frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. After the woven bag is placed on the first platform, the suction nozzle at the end of the air tube will adsorb the woven bag. Then, the upward-moving lifting tube frame will move the air tube upward to lift the upper part of the woven bag opening, causing the bag opening to open. Next, the first servo pusher cylinder will push the pusher frame and the fixed seat towards the first platform. At this time, the slide seat slides on the first platform for guidance. When the slide seat abuts against the positioning strip, the fixed seat will stop moving. At the same time, the upper and lower bag-opening discs will extend into the opening of the woven bag. Then, the pusher frame will continue to move towards the first platform. At this time, the support spring will deform to ensure that the pusher frame moves without obstruction. The continuing movement of the pusher frame will drive the two bag-opening frames to move, so that the upper bag-opening discs on the two H-shaped frames can move outward. The moving pusher also drives the pusher rail to move, using the raised end of the pusher rail to press the pressure roller, causing the lower bag sheet to move down and press the lower part of the woven bag opening onto the first platform. Then the pusher continues to move towards the first platform. During this process, the pressure roller rolls on the lower plane of the pusher rail, keeping the lower bag sheet pressing the lower part of the woven bag opening onto the first platform. At the same time, the bag-opening frame continues to push the H-shaped frame, causing the two upper bag-opening sheets to move outward synchronously, supporting the upper part of the woven bag opening from the inside of the woven bag, so that the woven bag opening is stretched and rounded. The process only requires placing the woven bag on the first platform, eliminating the need for workers to manually open the bag opening, thus effectively reducing the labor intensity of workers and making it convenient to use.

[0015] 2. As the two upper bag discs move outward synchronously and continuously to tighten and round the opening of the woven bag, when the opening of the woven bag is about to be rounded, the outward-moving upper bag disc will press against the pressing disc. Then the upper bag disc continues to move outward, pushing the pressing disc outward. At this time, the pressing spring deforms. Thus, when the opening of the woven bag is tightened and rounded, the thrust generated by the deformed pressing spring squeezes the pressing disc, pressing the opening of the woven bag tightly against the outside of the upper bag disc, thereby increasing the fixing force on the opening of the bag and ensuring that the woven bag will not loosen during the bagging process.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] This invention provides a technical solution: such as Figure 1 - Figure 8The illustrated fabric roll bag device includes a support 1. A first platform 2 is fixedly installed on one side of the upper end of the support 1. The first platform 2 supports the woven bag 37. Positioning strips 3 are embedded in the front and rear edges of the first platform 2. The positioning strips 3 position the woven bag 37 and the fixing seat 10. A vertical groove frame 12 is fixedly installed at the upper edge of the rear positioning strip 3. A lifting tube frame 4 is slidably installed through the vertical groove frame 12. The vertical groove frame 12 guides the lifting tube frame 4. An air pipe 14 is fixedly installed at one end, and a suction nozzle 15 is installed at the lower end of the air pipe 14. The air pipe 14 is connected to an external air pump, enabling the suction nozzle 15 to generate suction. Since this operation is existing technology and widely used, it is not described in detail here and is not shown in the figure. A fixed base 10 is slidably installed at the end of the first platform 2. H-shaped frames 16 are slidably installed at both ends of the fixed base 10. The fixed base 10 serves to support the H-shaped frames 16 and the lower bag disc 33. Upper... The upper bag disc 23 and the H-shaped frame 16 serve to support and guide the upper bag disc 23. A pusher frame 19 is elastically mounted on the side of the fixed base 10. A bag holder 18 connects the pusher frame 19 and the H-shaped frame 16. When the fixed base 10 stops moving, the continuously moving pusher frame 19 drives the two bag holders 18 to move, synchronously pushing the two H-shaped frames 16, allowing the upper bag discs 23 on the two H-shaped frames 16 to move outwards. A lower bag disc 33 is located below the two upper bag discs 23, and the lower bag disc 33 is connected to the fixed base 10. The seat 10 is elastically connected, and the lower end of the lower bag disc 33 is connected to the pressure seat 27. The middle of the lower end of the push frame 19 is fixedly installed with a pusher rail 29. The end of the pusher rail 29 is raised. The middle of the pressure seat 27 is rotatably installed with a pressure roller 28. The pressure seat 27 serves to support the pressure roller 28. The end of the pusher rail 29 presses on the pressure roller 28. The raised end of the pusher rail 29 presses on the pressure roller 28, causing the lower bag disc 33 to move down, so as to press the lower part of the bag opening of the woven bag 37 tightly onto the first platform 2. A pusher is provided on the other side of the upper end of the support 1.

[0027] The rear end of the positioning plate 3 is fixedly installed with a second servo push cylinder 11. The telescopic end of the second servo push cylinder 11 is fixed to the lifting tube frame 4. The second servo push cylinder 11 drives the lifting tube frame 4 to move. Two sliding seats 13 are symmetrically fixedly installed on the inner side of the fixed seat 10. The sliding seats 13 guide the fixed seat 10. The two sliding seats 13 are slidably installed on the front and rear edges of the first platform 2 respectively. The sliding seats 13 are located on the side of the positioning plate 3.

[0028] A guide seat 17 is slidably mounted on the outer surface of the H-shaped frame 16. The side of the guide seat 17 is fixed to the fixed seat 10. The guide seat 17 serves to allow the H-shaped frame 16 to slide. Two guide rods 35 are symmetrically fixed at the lower edge of the side of the fixed seat 10. The push frame 19 is slidably mounted on the outer surface of the guide rods 35. The guide rods 35 serve to guide the push frame 19. A support spring 34 is wound around the outside of the guide rods 35. One end of the support spring 34 is fixed to the fixed seat 10, and the other end of the support spring 34 is fixed to the push frame 19. When the fixed seat 10 stops moving and the push frame 19 continues to move in the direction of the first platform 2, the support spring 34 will deform, so that the movement of the push frame 19 will not be obstructed.

[0029] Two pressure-pressing discs 22 are provided opposite to the two upper bag discs 23. A guide prism 25 is fixedly installed in the middle of the pressure-pressing disc 22. A guide head 21 is slidably installed on the outer surface of the guide prism 25. The cooperation between the guide prism 25 and the guide head 21 guides the pressure-pressing disc 22. The end of the guide head 21 is fixed to the fixing base 10. A pressure-pressing spring 20 is wound around the outside of the guide head 21 and the guide prism 25. One end of the pressure-pressing spring 20 is fixed to the pressure-pressing disc 22, and the other end of the pressure-pressing spring 20 is fixed to the guide head 21. With the trapezoidal surfaces fixed, when the opening of the woven bag 37 is about to be stretched into a round shape, the outwardly moving upper bag sheet 23 will press against the bag pressing sheet 22. Then, the upper bag sheet 23 continues to move outward, pushing the bag pressing sheet 22 outward. At this time, the bag pressing spring 20 deforms. Thus, when the opening of the woven bag 37 is stretched and stretched into a round shape, the thrust generated by the deformed bag pressing spring 20 is used to squeeze the bag pressing sheet 22, so that the opening of the woven bag 37 is pressed tightly against the outside of the upper bag sheet 23 through the bag pressing sheet 22, thereby improving the fixing force on the opening of the bag.

[0030] Two seat rods 30 are symmetrically fixedly installed at the lower end of the lower bag disc 33. The lower end of the seat rod 30 is fixed to the pressure seat 27. An extension ear 26 is slidably installed on the outer surface of the seat rod 30. The seat rod 30 and the extension ear 26 serve to guide the lower bag disc 33. The end of the extension ear 26 is fixed to the fixed seat 10. A return spring 32 is wound around the outside of the seat rod 30. One end of the return spring 32 is fixed to the lower end of the lower bag disc 33. The return spring 32 serves to reset the lower bag disc 33 that has moved down. The other end of the return spring 32 is fixed to the upper end of the extension ear 26. A positioning cap 31 is coaxially embedded on the outer surface of the seat rod 30. The positioning cap 31 serves to position the lower bag disc 33 at its reset position. The positioning cap 31 fits against the lower end of the extension ear 26.

[0031] A second connector 39 is rotatably mounted on one end of the bag holder 18. The end of the second connector 39 is fixed to the end of the pusher frame 19. The second connector 39 facilitates the connection between the bag holder 18 and the pusher frame 19. A first connector 38 is rotatably mounted on the other end of the bag holder 18. The end of the first connector 38 is fixed to the end of the H-shaped frame 16. The first connector 38 facilitates the connection between the bag holder 18 and the H-shaped frame 16.

[0032] The pusher includes a second platform 6 fixedly installed on the other side of the upper end of the support 1. A roll support 5 is fixedly installed in the middle of the upper end of the second platform 6. The roll support 5 serves to support and position the fabric roll 36. A servo slide 7 is fixedly installed at the upper front edge of the upper end of the second platform 6. A pusher frame 8 is fixedly installed on the upper end of the slide of the servo slide 7. Multiple pusher claws 24 are fixedly installed in a circular array at the end of the pusher frame 8. The pusher claws 24 increase the contact surface with the fabric roll 36. When the servo slide 7 works, it drives the pusher claws 24 at the end of the pusher frame 8 to move, so as to push the fabric roll 36 on the roll support 5 into the woven bag 37 to complete the bagging.

[0033] A servo cylinder 9 is fixedly installed at the lower end of the second platform 6. The output end of the servo cylinder 9 is fixed to the push frame 19, and the servo cylinder 9 drives the push frame 19 to move.

[0034] In use, the fabric roll 36 is placed on the roll holder 5, and then the woven bag 37 is laid on the first platform 2. At this time, the positioning strip 3 is attached to the woven bag 37 to position it. At the same time, the suction nozzle 15 is attached to the woven bag 37. Then, the suction nozzle 15 at the end of the air tube 14 generates suction to adsorb the woven bag 37. Then, the second servo push cylinder 11 drives the lifting tube frame 4 to move upward, so that the air tube 14 moves upward to lift the upper part of the bag opening of the woven bag 37, making the bag opening of the woven bag 37 open. Then, the first servo push cylinder 9 pushes the push frame 19 and the fixed seat 10 towards the direction of the first platform 2. At this time, the slide seat 13 is in a... The slide guides the slide plate 2. When the slide seat 13 abuts against the positioning strip 3, the fixed seat 10 stops moving. At the same time, the upper bag sheet 23 and the lower bag sheet 33 extend into the opening of the woven bag 37. Then, the pusher 19 continues to move in the direction of the first platform 2. At this time, the support spring 34 deforms, so that the pusher 19 can move without obstruction. The continuing to move pusher 19 will drive the two bag-opening frames 18 to move, so as to push the two H-shaped frames 16 simultaneously, so that the upper bag sheet 23 on the two H-shaped frames 16 can move outward. At the same time, the continuing to move pusher 19 will also drive the pusher rail 29 to move, so as to use the raised end of the pusher rail 29 to press the pressure roller 28. Pressing down causes the lower bag sheet 33 to move downwards, pressing the lower part of the opening of the woven bag 37 against the first platform 2. Then, the pusher 19 continues to move towards the first platform 2. During this process, the pressure roller 28 rolls on the lower plane of the pusher rail 29, keeping the lower bag sheet 33 pressing the lower part of the opening of the woven bag 37 against the first platform 2. Simultaneously, the bag-opening frame 18 continues to push the H-shaped frame 16, causing the two upper bag-opening sheets 23 to move outwards synchronously, supporting the upper part of the opening of the woven bag 37 from the inside, thus tightening and rounding the opening of the woven bag 37. At this point, the suction nozzle 15 releases its suction on the woven bag 37. In the process, when the opening of the woven bag 37 is about to be stretched and rounded, the outwardly moving upper bag sheet 23 will press against the pressing bag sheet 22. Then the upper bag sheet 23 continues to move outward and pushes the pressing bag sheet 22 outward. At this time, the pressing bag spring 20 deforms. In this way, when the opening of the woven bag 37 is stretched and rounded, the thrust generated by the deformed pressing bag spring 20 is used to squeeze the pressing bag sheet 22, so that the opening of the woven bag 37 is pressed tightly against the outside of the upper bag sheet 23 through the pressing bag sheet 22, thereby improving the fixing force on the opening of the bag. Then the servo slide 7 works to drive the pusher claw 24 at the end of the pusher frame 8 to move, so as to push the fabric roll 36 on the roll support 5 into the woven bag 37, completing the bagging.
