When changing specifications or when it is necessary to adjust the distance between the left and right bag clamps or change the timing of opening the bag clamps at certain workstations, the distance between the left and right bag clamps cannot be adjusted at will. Disassembly is troublesome, and the adaptability is poor, which reduces the clamping efficiency for packaging bags of different sizes. Therefore, it is necessary to improve the bag making machine by providing an adjustable bag clamping device to solve the above problems. Utility Model Content

[0004] To overcome the problem that the left and right bag clamps in the bag clamp mechanism are directly installed on the device by bolts, resulting in a fixed position, making it impossible to adjust the distance between the left and right bag clamps at will, and causing troublesome disassembly and poor adaptability.

[0009] Preferably, the mounting frame has a groove at the corresponding position of the sliding block, and the sliding block slides in the groove.

[0010] Preferably, the clamping assembly includes a mounting frame, which is fixedly connected to the top of the mounting arm. A hydraulic telescopic rod is fixedly connected inside the mounting frame. A T-block is fixedly connected to the telescopic end of the hydraulic telescopic rod.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1 - Figure 5 This utility model provides an embodiment: an adjustable bag clamping device for a bag making machine, including a mounting frame 1, a limiting frame 26, and a clamping assembly. A fixing assembly is provided at the front end of the mounting frame 1, and the limiting frame 26 is fixedly connected to the front end of the mounting frame 1. A connecting block 27 is slidably connected inside the limiting frame 26, and a movable base 28 is fixedly connected to the front end of the connecting block 27. The movable base 28 is slidably connected to the outside of the limiting frame 26. The connecting block 27 drives the movable base 28 to slide outside the limiting frame 26, and the connecting block 27 also slides inside the limiting frame 26, causing two sets of movable bases 28 to slide synchronously in opposite directions outside the limiting frame 26. The distance between the two sets of clamping components can be flexibly adjusted to improve work efficiency. The clamping components are toothed on the inner side of the clamping block 37, and the clamping block 37 can be installed horizontally or vertically by bolts, so that the direction of the clamping block 37 can be adjusted according to the needs, thereby improving clamping stability. The limiting frame 26 has a groove at the corresponding position of the connecting block 27, and the connecting block 27 slides in the groove to limit the connecting block 27, thereby improving the sliding stability of the connecting block 27 and improving its practicality. The moving base 28 has a groove at the corresponding position of the limiting frame 26, and the moving base 28 slides outside the limiting frame 26 to limit the moving base 28, thereby improving stability.

[0021] Please see Figure 2 - Figure 3 In this embodiment, a motor 21 is fixedly connected inside the mounting frame 1, and a rotating shaft 22 is fixedly connected to the output end of the motor 21. The rotating shaft 22 is rotatably connected inside the mounting frame 1. A gear 23 is fixedly connected to the outside of the rotating shaft 22. A toothed plate 24 meshes with the outside of the gear 23. A sliding block 25 is fixedly connected to the rear end of the toothed plate 24. The sliding block 25 is slidably connected inside the mounting frame 1. A connecting block 27 is fixedly connected to the outside of the toothed plate 24. An mounting arm 29 is fixedly connected to the front end of the movable base 28, allowing it to freely adjust the distance between the left and right bag clamps, thereby improving the clamping efficiency for packaging bags of different sizes, eliminating the need for disassembly and assembly, and improving the adaptability of the device. The mounting frame 1 has a groove at the corresponding position of the sliding block 25, and the sliding block 25 slides in the groove, thereby limiting the sliding block 25 and improving the stability of the sliding block 25 during sliding.

[0022] Please see Figure 4 - Figure 5In this embodiment, the clamping assembly includes a mounting frame 31, which is fixedly connected to the top of the mounting arm 29. A hydraulic telescopic rod 32 is fixedly connected inside the mounting frame 31. A T-block 33 is fixedly connected to the telescopic end of the hydraulic telescopic rod 32. A movable bracket 34 is rotatably connected to the outside of the T-block 33. An optical axis 35 is fixedly connected inside the mounting frame 31. A rotating bracket 36 is rotatably connected to the outside of the optical axis 35. A bag clamping block 37 is fixedly connected to the inside of the rotating bracket 36 by bolts. The end of the rotating bracket 36 away from the bag clamping block 37 is rotatably connected to the inside of the movable bracket 34. The bag clamping block 37 is toothed on the inside and can be installed horizontally or vertically by bolts, so that the direction of the bag clamping block 37 can be adjusted according to the needs, thereby improving the clamping stability. The toothed shape of the bag clamping block 37 improves the clamping efficiency of the packaging bag.

[0023] During operation, the mounting frame 1 is installed on the equipment. The motor 21 is started, causing the rotating shaft 22 to rotate inside the mounting frame 1, which in turn drives the gear 23 to rotate. Two sets of gear plates 24 meshing with the gear 23 cause it to slide synchronously in opposite directions via the sliding block 25, maintaining the centering of the two clamping components. The connecting block 27 slides inside the limiting frame 26, causing the two sets of moving bases 28 to slide synchronously in opposite directions outside the limiting frame 26. This allows for flexible adjustment of the distance between the two clamping components, improving work efficiency. Activating the hydraulic telescopic rod 32 drives the T-block 33. The device is moved by a movable bracket 34 externally connected to the T-block 33, which is rotatably connected to the outside of the rotating bracket 36. This causes the rotating bracket 36 to rotate around the optical axis 35, clamping the packaging bag through the bag clamping block 37. The inner side of the bag clamping block 37 is toothed, and it can be installed horizontally or vertically with bolts. This allows the direction of the bag clamping block 37 to be adjusted as needed, improving clamping stability. It also allows for easy adjustment of the distance between the left and right bag clamps, improving the clamping efficiency for packaging bags of different sizes. This eliminates the need for disassembly and assembly, thus increasing the adaptability of the device.

[0024] Through the above steps, the connecting block 27 drives the movable base 28 to slide outside the limiting frame 26, allowing it to freely adjust the distance between the left and right bag clamps. This improves the clamping efficiency for packaging bags of different sizes and eliminates the need for disassembly, thus solving the problems of not being able to freely adjust the distance between the left and right bag clamps, cumbersome disassembly, and poor adaptability.
