[0029] like Figure 1-4 As shown, this utility model provides a cutting device for processing packaging bags, which has a processing table 1. The processing table 1 is provided with two sets of cutting components 2 and two sets of auxiliary components 3. One set of cutting components 2 includes a support plate 21 and a cutter 22 horizontally installed on the support plate 21. One set of auxiliary components 3 includes a sliding plate 31 and a cutting groove 32 horizontally opened on the sliding plate 31.

[0030] The cutter 22 is located directly above the cutting groove 32, and the processing table 1 is also equipped with an adjustment component for driving the cutting component 2 and the auxiliary component 3 to move synchronously.

[0031] The adjustment assembly includes a movable frame 41 fixedly installed on both long sides of the processing table 1, and two synchronously moving sliders 42 are slidably connected inside each movable frame 41.

[0032] Optionally, in the above technical solution, the fixed end of the telescopic cylinder 43 is fixedly connected to the top wall of the slider 42, and the movable end of the telescopic cylinder 43 on both sides extends upward and is fixedly connected to the end of the support plate 21.

[0033] Optionally, in the above technical solution, a support base 23 is fixedly installed on the front and rear walls of the support plate 21 of a set of cutting components 2. A T-shaped rod 24 is vertically slidably connected inside the support base 23. A pressure plate 25 is fixedly installed at the bottom end of the T-shaped rod 24. The two pressure plates 25 are symmetrically arranged about the cutting groove 32.

[0034] Optionally, in the above technical solution, a spring is sleeved on the T-shaped rod 24, and the two ends of the spring are respectively fixedly installed on the bottom wall of the support seat 23 and the top wall of the pressure plate 25.

[0035] Optionally, in the above technical solution, one end of an L-shaped rod 33 is fixedly connected to the side wall of the slider 42, and the other end of the L-shaped rod 33 on both sides is fixedly connected to both ends of the sliding plate 31.

[0036] Optionally, in the above technical solution, the groove 32 is formed at one end of the two sliding plates 31 that are close to each other, and the length of the sliding plate 31 is greater than the length of the cutter 22.

[0037] The width of the groove 32 is sufficient for the cutter 22 to extend into. The groove 32 is formed at one end of the two sliding plates 31 that are close to each other, so that the sliding plates 31 can be as close as possible.

[0038] The two side walls of the slider 42 abut against the inner side wall of the moving frame 41. The two sliders 42 in one moving frame 41 have opposite thread directions, which are adapted to the threads of the double-ended screw 44 on the same side.

[0039] In the T-shaped rod 24, when the spring is not compressed, the bottom wall of its crossbar rests against the top wall of the support seat 23. At this time, the spring is in a state of no force, and the pressure plate 25 will not stretch the spring.

[0040] The width between the two pressure plates 25 is greater than the width of the L-shaped rod 33.

[0041] Furthermore, the bottom wall of the sliding plate 31 is slidably connected to the top wall of the processing table 1, and the side wall of the sliding plate 31 is slidably connected to the side wall of the moving frame 41 on the same side; specifically, this can be achieved by installing sliding wheels on the bottom wall and side wall of the sliding plate 31.

[0042] Furthermore, each of the movable frames 41 is rotatably connected to a double-ended screw 44, and each of the sliders 42 has a screw hole corresponding to the double-ended screw 44. The sliders 42 are sleeved on both ends of the double-ended screw 44 and threadedly connected to them. The front wall of the movable frame 41 is provided with a drive motor fixedly installed on the processing table 1. The output shaft of the drive motor passes through the movable frame 41 and is connected to the double-ended screw 44 through a coupling.

[0043] Working principle:

[0044] When in use, adjust the distance between the two sliders 42 (the distance between the two cutters 22 and the distance between the two cutting grooves 32 move accordingly) according to the required cutting length, then place the packaging bag material to be cut on the two sliding plates 31, and start the telescopic cylinder 43 to retract its movable end to drive the support plate 21 to move down.

[0045] This causes the cutter 22 and pressure plate 25 to move downwards (in the initial state, the movable end of the telescopic cylinder 43 is fully extended). When the cutter 22 is about to contact the packaging bag (i.e., the bottom surface of the cutter 22 is slightly higher than the top surface of the sliding plate 31), the pressure plate 25 presses on the packaging bag and works with the sliding plate 31 to clamp the packaging bag. When the movable end of the telescopic cylinder 43 is fully retracted, the bottom edge of the cutter 22 abuts against the bottom wall of the cutting groove 32, cutting the packaging bag. Under the action of the spring, pressure is applied to the pressure plate 25, so that the packaging bag can be clamped and prevent the packaging bag from moving during cutting (i.e., during cutting, the pressure plate 25 first presses the packaging bag tightly against the top wall of the sliding plate 31 so that the packaging bag will not slide when it is cut, and then the cutter 22 continues to move downwards to cut).

[0046] The cutting component 2 and the auxiliary component 3 move as follows: the drive motor is started to drive the double-headed screw 44 to rotate within the moving frame 41, and the two sliders 42 move synchronously towards or away from each other through threaded connection with the double-headed screw 44; the cutting component 2 moves with the slider 42 via the telescopic cylinder 43, and the auxiliary component 3 moves with the slider 42 via the L-shaped rod 33.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
