[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-4 :

[0026] A fabric folding mechanism for a bag opening machine includes a frame 2 with a worktable 1. A fabric folding mechanism 3 is disposed below the worktable 1. The fabric folding mechanism 3 is slidably disposed on a base 4 fixedly connected to the frame 2. When working, the fabric folding mechanism 3 is in the working position corresponding to the slot 5. When maintaining the machine, it slides to the maintenance position outside the frame 2. When the fabric folding mechanism 3 is in the working position, it is locked by a rear locking mechanism. When it is in the maintenance position, it is locked by a front locking mechanism.

[0027] Comparison Appendix Figures 1 to 3The working method of this embodiment is as follows: In the normal working position, the folding mechanism 3 is located in the working position and locked by the rear locking mechanism. The folding mechanism 3, the base 4, and the frame 2 are all in a fixed state. The folding mechanism 3 works normally according to the working process of the existing bag opening machine folding mechanism 3. When maintenance is required, the rear locking mechanism is unlocked, and the folding mechanism 3 can slide along the base 4 and be pulled out to the maintenance position outside the frame 2. Then, it is locked by the front locking mechanism, so that the folding mechanism 3 is fixed again with the base 4 and the frame 2. After maintenance is completed, the front locking mechanism is unlocked, and the folding mechanism 3 can slide along the base 4 and be pushed in to the working position. Then, it is locked again by the rear locking mechanism.

[0028] To ensure the stable sliding of the folding mechanism 3, preferably, the base 4 is located entirely within the frame 2 below the workbench 1 and is fastened to the frame 2 by fasteners.

[0029] In this embodiment, the sliding structure of the folding mechanism 3 is as follows: a first slide rail 6 is laid on the base 4 in a longitudinal direction, a sliding seat 7 is slidably arranged on the first slide rail 6, and the folding mechanism 3 is arranged on the sliding seat 7; preferably, the first slide rail 6 is arranged in pairs and connected to the sliding seat 7 by a slider.

[0030] In this embodiment, the specific structure of the front locking mechanism is as follows: a front limiting bolt 8 is provided on the front side of the base 4, and a front limiting block 9 is provided at the bottom of the sliding seat 7. When the front end face of the front limiting block 9 abuts against the front limiting bolt 8, a front limiting structure for the sliding seat 7 is formed. A front quick clamp 10 is provided on the front side of the base 4. The rubber head of the front quick clamp 10 abuts against the side wall of the sliding seat 7 to form a front locking mechanism. During the process of pulling out the folding mechanism 3, when the front limiting block 9 abuts against the front limiting bolt 8, the folding mechanism 3 has moved to the maintenance position. At this time, the front quick clamp 10 can be moved to lock the sliding seat 7. During maintenance, the folding mechanism 3 only needs to be roughly locked. Therefore, only one front locking mechanism is provided, which is located on the left or right side of the base 4 and the sliding seat 7.

[0031] In this embodiment, the specific structure of the rear locking mechanism is as follows: a locking block 11 is provided on the side of the sliding seat 7, a locking seat 12 is provided on the base 4, and a rear quick clamp 13 is provided on the locking seat 12. When the sliding seat 7 slides to the working position, the rear side of the locking block 11 abuts against the front side of the locking seat 12, and the rubber head of the rear quick clamp 13 clamps the front side of the locking block 11 to form the rear locking mechanism. During the process of pushing the folding mechanism 3 inward, when the locking block 11 abuts against the locking seat 12, the folding mechanism 3 has moved to the working position. At this time, the rear quick clamp 13 can be moved to lock the sliding seat 7. During operation, the folding mechanism 3 needs to be fully locked. Therefore, a pair of rear locking mechanisms are provided, located on the left and right sides of the base 4 and the sliding seat 7, respectively.

[0032] Comparison Appendix Figure 4 In this embodiment, the specific structure of the folding mechanism 3 is as follows: a vertically distributed second slide rail 14 is provided on the front side of the sliding seat 7, a folding slide table 15 is slidably disposed on the second slide rail 14, a first motor 16 is provided on the sliding seat 7 to drive the folding slide table 15 to slide vertically, and an avoidance notch 17 is provided on the base 4 to cooperate with the first motor 16; a longitudinally distributed third slide rail 18 is provided on the folding slide table 15, and a front folding fork plate 19 and a rear folding fork plate are slidably disposed on the third slide rail 18. The fabric fork plate 20 is provided, and the fabric folding slide 15 is equipped with a second motor 21 that drives the front fabric folding fork plate 19 and the rear fabric folding fork plate 20 to open and close. Preferably, the second slide rail 14 is arranged in pairs and connected to the fabric folding slide 15 through a slider, and the third slide rail 18 is arranged in pairs and connected to the front fabric folding fork plate 19 and the rear fabric folding fork plate 20 through sliders respectively. During operation, the first motor 16 drives the fabric folding slide 15 to move upward, and the second motor 21 drives the front fabric folding fork plate 19 and the rear fabric folding fork plate 20 to move to both sides to complete the fabric folding.

[0033] Furthermore, the first motor 16 is driven by the first ball screw 22, which is equipped with a first nut fixed to the folding slide 15; the second motor 21 is driven by the second ball screw 23, which is provided with front and rear threaded sections with opposite threads, and the front and rear threaded sections are respectively equipped with a second nut fixed to the front folding fork plate 19 and a third nut fixed to the rear folding fork plate 20; the first motor 16 drives the first ball screw 22 to rotate, and drives the folding slide 15 to move up and down through the first nut; the second motor 21 drives the second ball screw 23 to rotate, and the front and rear threaded sections on the second ball screw 23 rotate in different directions, thereby causing the second nut and the third nut to move in different directions, and finally causing the front folding fork plate 19 and the rear folding fork plate 20 to move towards or away from each other.

[0034] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
