Description

Technical Field

[0001] This utility model relates to the field of fabric spreading machine technology, specifically a fabric spreading machine for bag production. Background Technology

[0002] Bags and luggage are a general term for bags, including shopping bags, handbags, backpacks, shoulder bags, and suitcases. As people's living standards and consumption levels continue to improve, all kinds of bags and luggage have become indispensable accessories for people. In the production process of bags and luggage, a fabric laying machine is used to lay the fabric flat so that workers can cut the fabric.

[0003] According to a fabric spreading machine for bag production with application number 202322262305.7, the fabric roll is placed on the outside of the feeding roller, and the feeding roller is driven by a motor to move the feeding roller and move the fabric to the surface of the placing table. Then the fabric moves to the top of the base plate, and the first electric telescopic rod is activated to push the pressure plate to press and fix the position of the fabric. The electric slider slides inside the moving groove to pull the fabric to move and adjust the size of the fabric spreading. The fabric released by the device is flattened by the flattening structure.

[0004] However, the above-mentioned fabric spreading machine has certain shortcomings. Generally speaking, the weight of the fabric rolls used in bag production is mostly tens to hundreds of kilograms, which makes the fabric rolls quite heavy. The feeding roller of the above-mentioned fabric spreading machine is set at a high position above the placement table, and there is no feeding mechanism. Due to the heavy weight of the fabric rolls, manual feeding is time-consuming and laborious, which is inconvenient during the feeding process. Therefore, we propose a fabric spreading machine for bag production. Utility Model Content

A take-up reel shaft is fixedly mounted at the output end of the second dual-axis motor. A lifting cable is wound around the outer side of the take-up reel shaft, and a hook is fixedly mounted at one end of the lifting cable.

[0007] Furthermore, negative pressure grooves are provided inside both sides of the fabric laying table, and an air hood is fixedly installed at the bottom of the fabric laying table and below the negative pressure grooves. Two high-pressure vacuum pumps are fixedly installed on the top of the base plate, and the input end of the high-pressure vacuum pump is fixedly connected to the output end of the air hood.

[0008] Furthermore, a fixing frame is fixedly installed on both sides of the top of the spreading table, and two electric telescopic rods are fixedly installed on the top of the fixing frame. The output end of the electric telescopic rod extends to the inner side of the fixing frame and a fixing pressure plate is fixedly installed thereon.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a fabric spreading machine for bag production, including a base plate 1 and a spreading table 2. A concave groove 3 is formed inside the top of the base plate 1. Lead screws 4 are rotatably mounted on both sides of the concave groove 3. A driven bevel gear 5 is fixedly mounted on the outer side of the lead screw 4. A first dual-shaft motor 6 is fixedly mounted in the middle of the concave groove 3. A transmission shaft 7 is fixedly mounted at the output end of the first dual-shaft motor 6. A driving bevel gear 8 is fixedly mounted at one end of the transmission shaft 7, meshing with the driven bevel gear 5. A sleeve block 9 is threaded onto the outer side of the lead screw 4. A portal frame 10 is fixedly mounted on the top of the sleeve block 9. A second dual-shaft motor 11 is fixedly mounted in the middle of the top of the portal frame 10. A take-up reel shaft 12 is fixedly installed at the output end of the shaft motor 11. A lifting cable 13 is wound around the outside of the take-up reel shaft 12. A hook 14 is fixedly installed at one end of the lifting cable 13. The rotation of the transmission shaft 7 driven by the first dual-shaft motor 6 can drive the lead screw 4 to rotate through the meshing of the active bevel gear 8 and the driven bevel gear 5 at one end of the transmission shaft 7. The screw drives the sleeve block 9 to move, which can drive the portal frame 10 to move horizontally left and right, thus playing the role of lifting and feeding the fabric roll 19. When lifting the fabric roll, the second dual-shaft motor 11 is turned on to drive the take-up reel shaft 12 to rotate, and the lifting cable 13 is extended so that the hook 14 falls. The fabric roll 19 can be lifted by the engagement of the hook 14 with the shaft of the fabric roll 19, thus feeding the fabric.

[0021] Negative pressure grooves 22 are provided on both sides of the fabric laying table 2. An air cover 23 is fixedly installed at the bottom of the fabric laying table 2 and below the negative pressure grooves 22. Two high-pressure vacuum pumps 24 are fixedly installed on the top of the base plate 1. The input end of the high-pressure vacuum pump 24 is fixedly connected to the output end of the air cover 23. With the arrangement of the negative pressure grooves 22, air cover 23 and high-pressure vacuum pumps 24, when the fabric is fixed, the air in the negative pressure grooves 22 and air cover 23 can be extracted by the high-pressure vacuum pumps 24 to form a negative pressure environment in the negative pressure grooves 22, thereby adsorbing the fabric laid on the fabric laying table 2 and playing a role in positioning the fabric.

[0022] Both sides of the top of the fabric laying table 2 are fixedly installed with a fixing frame 25. Two electric telescopic rods 26 are fixedly installed on the top of the fixing frame 25. The output end of the electric telescopic rod 26 extends to the inside of the fixing frame 25 and a fixing plate 27 is fixedly installed thereon. After the fabric is laid out and positioned above the negative pressure groove 22 by negative pressure adsorption, the fixing plate 27 can be pushed down by opening the electric telescopic rod 26, thereby fixing one end of the fabric through the fixing plate 27, which can achieve the function of fixing the fabric.

[0023] Linear guide rails 15 are provided on both sides of the fabric laying table 2. An electric slider 16 is slidably mounted on the outer side of the linear guide rails 15. A mounting bracket 17 is fixedly mounted on the top of the electric slider 16. Shaft supports 18 are fixedly mounted on both sides of the top of the mounting bracket 17. A fabric roll 19 is rolled on the inner side of the shaft support 18. Both the linear guide rails 15 and the electric slider 16 are existing technologies, serving to drive the mounting bracket 17 to move horizontally. The shaft support 18 is divided into upper and lower parts, one of which... One side is connected by a hinge, and the other side is fixed by bolts. The middle part is provided with a hole and ball bearing that mates with the shaft in the middle of the fabric roll 19. When feeding the fabric roll 19, first loosen the bolt on one side of the shaft bracket 18, then flip the upper part of the shaft bracket 18 and rotate it around the hinge. Then, the fabric roll 19 is lifted and placed into the hole in the middle of the shaft bracket 18 by the hook 14 engaging with the shaft of the fabric roll 19. Then, the shaft bracket 18 is flipped to limit the shaft and fixed by bolts to complete the feeding of the fabric roll 19.

[0024] The top of the mounting frame 17 has an internal slot 20, and two guide rollers 21 are rotatably mounted inside the slot 20. With the slot 20 and guide rollers 21, the fabric that is extended on the outside of the roll 19 during unwinding can pass through the middle of the two guide rollers 21 in the slot 20 and be guided by the guide rollers 21.

[0025] The concave groove 3 is provided with a shaft support that mates with the drive shaft 7, and both sides of the top of the gantry frame 10 are provided with shaft supports that mate with the take-up wheel shaft 12. By providing shaft supports that mate with the drive shaft 7 inside the concave groove 3, the stability of the first dual-axis motor 6 when it drives the drive shaft 7 to rotate can be improved. The shaft supports on the top of the gantry frame 10 that mate with the take-up wheel shaft 12 improve the stability of the take-up wheel shaft 12 when it rotates.

[0026] In summary, when using this fabric spreading machine for bag production, the fabric roll 19 is first hoisted. During hoisting and loading, the bolts on one side of the shaft bracket 18 are loosened first, and then the upper half of the shaft bracket 18 is flipped and rotated around the hinge. Then, the second dual-axis motor 11 is turned on to drive the winding wheel shaft 12 to rotate. The winding wheel shaft 12 releases the lifting cable 13, and then the hook 14 is lowered. The hook 14 engages with the shaft of the fabric roll 19 to hook the shaft. Then, the second dual-axis motor 11 is turned on in reverse, and the winding wheel shaft 12 releases the lifting cable 13. 3. The fabric roll 19 is lifted by winding. After the fabric roll 19 is lifted, the first dual-shaft motor 6 is turned on to drive the transmission shaft 7 and the active bevel gear 8 to rotate. The active bevel gear 8 meshes with the driven bevel gear 5 and drives the lead screw 4 to rotate. The lead screw 4 drives the sleeve block 9, the gantry frame 10 and the lifted fabric roll 19 to move above the shaft support 18 through the thread. Then the fabric roll 19 is placed in the hole in the middle of the shaft support 18. Then the shaft support 18 is flipped to limit the shaft and fixed with bolts to complete the feeding of the fabric roll 19.

[0027] The fabric wrapped around the outside of the fabric roll 19 is then passed through the middle of the two guide rollers 21 inside the through groove 20, and then placed below the fixing frame 25. First, the air in the fabric air cover 23 and the negative pressure groove 22 is extracted by turning on the high-pressure vacuum pump 24, so that the negative pressure in the negative pressure groove 22 will adsorb and position one end of the fabric on the negative pressure groove 22. Then, the electric telescopic rod 26 is turned on to push the fixing plate 27 down to fix one end of the fabric on the laying table 2. Then, the electric slider 16 can move outside the linear guide rail 15 to drive the mounting frame 17. When the mounting frame 17 moves horizontally, the fabric roll 19 rotates within the shaft bracket 18 via the shaft to unroll the fabric, which can then be laid on the laying table 2. After cutting one side of the fabric, the air in the fabric air cover 23 and the negative pressure groove 22 is extracted by the high-pressure vacuum pump 24 on the other side of the laying table 2, so that the negative pressure in the negative pressure groove 22 adsorbs and positions the other end of the fabric on the negative pressure groove 22. Then, the electric telescopic rod 26 is turned on to push the fixed pressure plate 27 down to fix one end of the fabric on the laying table 2, thus completing the laying of the fabric.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
