Description

Technical Field

[0001] The utility model relates to the technical field of coating and printing, in particular to a cutting mechanism with an approaching pressure roller device. Background Art

[0002] In the production process of glass fiber cloth under the existing technology, a large roll of glass fiber cloth is first made from the blank cloth. However, glass fiber cloth with different functions has different width requirements. Therefore, when the glass fiber cloth passes through the coating machine, the glass fiber cloth will be cut into sizes of different widths by a cutter installed on the coating machine to meet the width requirements of different functions. After the cutter works, the distance between the material and the pressure roller will change, and the pressure roller cannot straighten the material, which affects the material cutting or coating work. At this time, it is necessary to manually move the pressure roller or the material to tighten the material, which leads to a waste of labor and working hours, and greatly reduces production efficiency. Utility Model Content

[0003] In order to solve the above existing problems, the utility model provides a cutting mechanism with a proximity type pressing roller device. The utility model is implemented through the following technical solutions.

[0004] A cutting mechanism with an approaching pressure roller device comprises a cutting slide plate which is arranged opposite to each other, an upper cutting knife assembly, a lower cutting knife assembly and a pressure roller assembly which are arranged on the inner side of the cutting slide plate, the pressure roller assembly being arranged between the upper cutting knife assembly and the lower cutting knife assembly, a linear moving assembly being arranged on the top of the cutting slide plate, the linear moving assembly comprising a driving motor and a synchronous rack, the synchronous rack being arranged on the top of the cutting slide plate, the output end of the driving motor being connected to a synchronous rotating shaft, the synchronous rotating shaft being provided with a synchronous gear corresponding to the synchronous rack, the synchronous gear being meshed with the synchronous rack; a moving slide groove and a moving slide rail which cooperate with each other are also arranged on the upper part of the cutting slide plate, the moving slide groove is fixedly connected to the cutting slide plate, the moving slide groove is arranged outside the moving slide rail and can slide along the moving slide rail; a photoelectric beam switch is also arranged on the cutting slide plate in front of the pressure roller assembly, the photoelectric beam switch being electrically connected or signal connected to the driving motor.

[0005] Furthermore, the upper cutter assembly has the same structure as the lower cutter assembly, both including a cutter, a cutter holder and a cutter cylinder. The rear end of the cutter is connected to the output end of the cutter cylinder, the cutter holder and the cutter cylinder are fixedly connected to the cutter slide, and the cutter holder is arranged in the cutter holder and can move along the cutter holder.

[0006] Furthermore, the pressure roller assembly includes a pressure roller slide, a pressure roller slider and a pressure roller cylinder. The pressure roller slide and the pressure roller cylinder are fixedly connected to the cutter slide. The pressure roller slide is provided with a pressure roller slide rail. The front end of the pressure roller slider is rotatably connected to the pressure roller, and the rear end of the pressure roller slider is connected to the output end of the pressure roller cylinder. The pressure roller slider is sleeved outside the pressure roller slide rail and can slide along the pressure roller slide rail.

[0007] Furthermore, the distance between the material and the cutter slide is the same as the width of the sensing area of ​​the photoelectric beam switch.

[0008] Beneficial effects of the utility model:

[0009] 1. The photoelectric switch senses the material position. If the material is in the sensing area of ​​the photoelectric switch, the material is not tightened. At this time, the drive motor is started to move the cutter slide backward until the material is no longer in the sensing area of ​​the photoelectric switch. At this time, the material is pulled closer again, so that the material state is automatically judged and the position of the pressure roller is automatically adjusted to tighten the material again.

[0010] 2. The change of the pressure roller position is completed by moving the cutter slide, so as to avoid the problem that the length of the pressure roller cylinder is increased due to the lengthening of the pressure roller stroke alone, which increases the overall area of ​​the cutter slide without changing the installation.

The shaft 11 is sleeved with a synchronous gear 12 corresponding to the synchronous rack 10, and the synchronous gear 12 is meshed with the synchronous rack 10; the upper part of the cutter slide 1 is also provided with a movable slide groove 18 and a movable slide rail 19 that cooperate with each other, and the movable slide groove 18 is fixedly connected to the cutter slide 1, and the movable slide groove 18 is sleeved outside the movable slide rail 19 and can slide along the movable slide rail 19; the cutter slide 1 in front of the pressure roller assembly 16 is also provided with a photoelectric beam switch 14, and the photoelectric beam switch 14 is electrically connected or signal connected to the drive motor 17.

[0021] The upper cutter assembly 2 and the lower cutter assembly 3 have the same structure, both including a cutter 4, a cutter holder 5 and a cutter cylinder 6. The rear end of the cutter 4 is connected to the output end of the cutter cylinder 6. The cutter holder 5 and the cutter cylinder 6 are both fixedly connected to the cutter slide 1. The cutter 4 is mounted in the cutter holder 5 and can move along the cutter holder 5.

[0022] The pressure roller assembly 16 includes a pressure roller slide plate 8, a pressure roller slider and a pressure roller cylinder 9. The pressure roller slide plate 8 and the pressure roller cylinder 9 are fixedly connected to the cutter slide plate 1.
