[0002] With the continuous development of automated production lines, the requirements for production efficiency and equipment flexibility are becoming increasingly stringent. In some production processes, especially those involving bag clamping and conveying, traditional clamping devices face problems such as limited space, rigid dimensions, and complex structures, which seriously affect equipment compatibility, maintenance efficiency, and production capacity.
[0003] Current technology exposes the cylinders of the left and right clamping assemblies on the left and right sides. This makes the cylinders prone to dust accumulation, requiring frequent maintenance and increasing costs. Moreover, it also results in a wider volume on both sides, leading to lower dimensional compatibility. Therefore, the size is easily limited when implementing single or multi-channel systems.

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0025] In one embodiment, a single / multi-channel bag clamping device, see [link / reference] Figures 1-2 It includes the left clamp assembly 2 and the right clamp assembly 7, and also includes:
[0026] Slide rail 1 is movably connected to the left clamp assembly 2 and the right clamp assembly 7. Slide rail 1 is provided with multiple screw holes. Slide rail 1 is mounted on the clamp base fixing plate. Slide rail 1 and the clamp base fixing plate are provided with multiple screw holes for connecting slide rail 1. The left clamp assembly 2 and the right clamp assembly 7 are movably mounted on slide rail 1 through the groove of slider 28.
[0027] An inverted octagonal plate 5 is disposed on one side of the clamp fixing plate and below the left clamp assembly 2 and the right clamp assembly 7. The inverted octagonal plate 5 is mounted on the cylinder frame 8.
[0028] See Figures 1-4 The clamping plate is provided with a bearing 6, which is movably connected to the left clamping assembly 2 and the right clamping assembly 7.
[0029] Further, see Figures 1-4 An octagonal adjustment plate 11 is provided on the left clamp assembly 2. The octagonal adjustment plate 11 is connected to an octagonal plate 12. The octagonal plate 12 is connected to a spring 13. The spring 13 is connected to the octagonal adjustment plate 11.
[0030] See Figures 1-4 The inverted octagonal plate 5 is provided with a slider 2 4, which is movably connected to the slide rail 2 3. The slider 2 4 is connected to the output end of the cylinder 2 9, which is mounted on the cylinder frame 8.
[0031] See Figures 1-4The left clamping assembly 2 includes a clamping arm 21, a clamp 22, a cylinder 23, a cylinder 24, a front clamping plate 25, an inner clamping plate 26, a clamping seat 27, and a slider 28. The clamping arm 21 is movably connected to the slide rail 1. The clamp 2 is connected to the clamping arm 21. The clamp 22 is provided with a front clamping plate 25, which is connected to the inner clamping plate 26. The clamping arm 21 is connected to the clamping seat 27. A clamping seat 27 is provided on one side of the clamping seat 27, and a slider 28 is provided on the clamping seat 27.
[0032] In this embodiment, the cylinder 24 is retracted, and the left and right clamps 22 are smaller in size, thus enabling multiple channels or more than two channels, and allowing for a wider range of compatible sizes without increasing the size of the clamp fixing plate and the overall machine.
[0033] Because the cylinder 124 has been modified to be concealed, it occupies less space and can achieve single-channel or more than two-channel operation, thus meeting more size requirements. This is the core improvement.
[0034] When multiple bags need to be packaged, if the bags are large, adjust the height of the inverted octagonal plate 5. When the inverted octagonal plate 5 moves upward, it moves the left clamping assembly 2 and the right clamping assembly 7 away from each other to accommodate larger bags. When the inverted octagonal plate 5 moves downward, it moves the left clamping assembly 2 and the right clamping assembly 7 closer together to accommodate smaller bags.
[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
