DETAILED DESCRIPTION

[0021] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-3 As shown, the fixed cutting device for the rolled bubble sheet for packaging comprises: a workbench 1, and a slide groove 3 is provided above the workbench 1 and near the front end.

[0023] A protective shell 2 is fixedly connected to the side of the workbench 1, and a first motor 16 is fixedly installed inside the protective shell 2. The output shaft of the first motor 16 passes through the protective shell 2 and the side of the workbench 1 and is fixedly connected to a double-headed screw rod 15, and the outer ends of the double-headed screw rod 15 are provided with threads of opposite rotation directions.

[0024] The other end of the double-ended screw rod 15 is rotatably connected to the inner wall of the workbench 1 , and a slider 17 is symmetrically threadedly connected to the outer side of the double-ended screw rod 15 near both ends.

[0025] The first motor 16 is started, and the output shaft of the first motor 16 drives the double-headed screw 15 to rotate, so that the two sliders 17 move closer to each other or farther away from each other.

[0026] The upper end of the slider 17 is fixedly connected to a connecting block 18, the interior of the connecting block 18 is hollow, and the upper end of the connecting block 18 is slidably connected to a blade 22, the side of the blade 22 is fixedly connected to a screw 20, and the side of the connecting block 18 is provided with a connecting groove 19, the connecting groove 19 is connected to the interior of the connecting block 18, and the screw 20 passes through the connecting groove 19 and is threadedly connected to a nut 21.

[0027] When the blade 22 is not in use, it is set inside the connecting block 18 to prevent the staff from accidentally touching it. When the bubble sheet needs to be cut, the screw 20 together with the blade 22 is lifted up by hand until the blade 22 is completely exposed from the inside of the connecting block 18, and the nut 21 is threadedly connected to the screw 20 to fix the blade 22.

[0028] Two fixed blocks 6 are symmetrically arranged at the upper end of the workbench 1, two forming rollers 7 and two guide rollers 8 are arranged between the two fixed blocks 6, a second motor 4 is arranged on the right side of the two forming rollers 7, and a third motor 5 is arranged on the right side of the two guide rollers 8.

[0029] An N-shaped frame 9 is arranged at the upper end and near the rear of the workbench 1, and a hydraulic cylinder 12 is fixedly arranged at the upper end of the N-shaped frame 9. The output end of the hydraulic cylinder 12 passes through the upper end of the N-shaped frame 9 and is fixedly connected to a connecting rod 10, and a cutter 11 is arranged at the lower end of the connecting rod 10.

[0030] A guide rod 14 is fixedly connected to the upper end of the connecting rod 10 and close to the two sides. The top end of the guide rod 14 passes through the upper end of the N-shaped frame 9 and is fixedly connected to the limiting block 13 .

[0031] The function of the guide rod 14 is to provide guide support during the cutting process, ensure the stability of the movement trajectory of the cutter 11, prevent deviation and shaking during the cutting process, and thus improve the cutting stability.

[0032] The function of the limit block 13 is to limit the maximum stroke of the cutter 11 to prevent the cutting range from exceeding the preset range during the cutting process. By setting the limit block 13, the stability and accuracy of the cutting can be ensured to prevent errors and unnecessary cutting.

[0033] Working principle:

[0034] When it is necessary to cut the bubble sheet, manually lift the screw 20 together with the blade 22 until the blade 22 is completely exposed from the inside of the connecting block 18, and threadably connect the nut 21 to the screw 20 to fix the blade 22; start the first motor 16, and the output shaft of the first motor 16 drives the double-headed screw 15 to rotate, so that the two sliders 17 are close to or away from each other. After the two sliders 17 are adjusted to the required positions, the bubble sheet can be sent to the cutting equipment. Bubble sheets of different widths can be cut by adjusting the position of the slider 17 outside the double-headed screw 15.

[0035] After the bubble sheet is fed into two forming rollers 7, it is fed into between two guide rollers 8. The two blades 22 will automatically cut the bubble sheet into the required width. Then, after the second motor 4 and the third motor 5 are turned on, the bubble sheet will be automatically transported to the lower end of the cutter 11. The hydraulic cylinder 12 is started to drive the cutter 11 to move downward to carry out detailed bubble sheet cutting production.

[0036] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
