Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing equipment, in particular to a non-woven fabric unwinding and cutting device. Background Art

[0002] Non-woven fabrics have been widely used in many fields such as medical care, industrial protection, and daily necessities due to their advantages such as high production efficiency, low cost, and wide application. In the production process of non-woven bags, continuous non-woven fabric rolls usually need to be cut according to certain specifications for subsequent use. Traditional non-woven fabric cutting methods mostly use fixed cutting tools, which have the following problems:

[0003] The cutting length is single, which makes it difficult to meet the needs of products with different specifications;

[0004] Changing the cutting size requires stopping the machine for adjustment, which affects production efficiency;

[0005] The fixed cutting mechanism has poor adaptability to non-woven fabrics of different thicknesses or materials.

[0006] Therefore, the existing non-woven fabric unwinding and cutting equipment has certain limitations in practical applications and cannot well meet the urgent needs of modern industrial production for high efficiency, flexibility, and automation. In order to overcome the above shortcomings and improve the flexibility and automation level of the non-woven fabric cutting process, it is necessary to develop a new type of non-woven fabric unwinding and cutting device.

[0009] Furthermore, the power mechanism is a pneumatic cylinder, an electric cylinder or a linear motor.

[0010] Furthermore, the cutting device includes a mounting strip, a fixed screw head, a slide rail fixed on the mounting strip, a plurality of sliders slidably arranged on the slide rail, a cutter fixed on the slider, and a spacing adjustment plate arranged on the slider, wherein the spacing adjustment plate is provided with a plurality of adjustment slots at intervals, the slider is provided with a screw hole, and the screw of the fixed screw head passes through the adjustment slot and is threadedly connected to the screw hole.

[0011] Furthermore, a driving motor for driving the unwinding roller to rotate is fixed on the side plate of the roller shaft, and the driving motor is connected to the roller shaft through a pulley.

[0012] Furthermore, a box body is provided on the outer side of the roller shaft side plate, a door is provided on the box body, and the pulley is arranged in the box body.

[0013] Furthermore, a transition roller is provided between the unwinding roller and the cloth discharging roller.

[0014] The beneficial effects of the utility model are:

[0015] 1. Enhanced flexibility: The slide rail assembly installed on the cutting mounting plate allows the cutting device to slide along the rail, allowing the cutting position to be adjusted according to actual needs. This allows the cutting size to be quickly adjusted without stopping the machine using the power mechanism, greatly improving the flexibility and adaptability of the equipment.

[0016] 2. Easy to operate: Since a power mechanism is used to drive the movement of the cutting device, the operator can adjust the cutting position through simple control operations (such as buttons or touch screens), which simplifies the operation process and reduces the difficulty of operation.

[0017] 3.

[0029] The utility model provides a non-woven fabric unwinding and cutting device.

[0030] In this embodiment, referring to Figure 1-4The non-woven fabric unwinding and cutting device comprises roller shaft side plates 1 arranged in parallel on both sides, an unwinding roller 2 arranged between the two roller shaft plates 1, and a cloth outlet roller 3 arranged between the two roller shaft plates, wherein the cloth outlet roller 3 is provided with a cutting device 20 on one side, the roller shaft side plates are fixed with cutting mounting plates 4 on both sides, the cutting device is slidably arranged on the cutting mounting plate through a sliding rail sliding block assembly 5, a power mechanism 6 is further fixed on the roller shaft side plate 1, and the output end of the power mechanism 6 is connected with the cutting device for driving the cutting device to move close to or away from the cloth outlet roller.

[0031] In the above technical solution, the cutting device is arranged on the sliding rail sliding block assembly and driven by the power mechanism to slide along the sliding rail of the sliding rail sliding block assembly, so that the cutting position is dynamically adjusted, and the cutting length can be quickly changed according to different production requirements. The use of the power mechanism enables the cutting device to automatically move close to or away from the cloth outlet roller, reduces manual intervention, and improves the automation level of the cutting process. Since the cutting device can quickly adjust the position, frequent shutdown is not required, and the production efficiency is effectively improved.

[0032] Specifically, the power mechanism is a pneumatic cylinder, an electric cylinder or a linear motor.

[0033] Specifically, the cutting device comprises a mounting strip plate 7, a fixed screw head 8, a sliding rail 9 fixed on the mounting strip plate, a plurality of sliding blocks 10 slidably arranged on the sliding rail, a cutting knife 11 fixed on the sliding block, and a spacing adjustment plate 12 arranged on the sliding block, wherein a plurality of adjustment long grooves 13 are arranged on the spacing adjustment plate at intervals, screw holes 14 are arranged on the sliding block, and the screw rod of the fixed screw head is threadedly connected with the screw holes through the adjustment long grooves.

[0034] In this embodiment, the combination of the adjustment long grooves and the fixed screw head can finely adjust the position of each cutting knife without changing the overall position of the cutting device, so that more accurate cutting is achieved. The design of the spacing adjustment plate enables the operator to conveniently adjust the distance between the cutting knives, thereby simplifying the operation steps.

[0035] Specifically, a driving motor 15 for driving the unwinding roller to rotate is fixed on the roller shaft side plate 1, and the driving motor 15 is drivingly connected with the roller shaft through a belt pulley 16.

[0036] The driving motor drives the unwinding roller to rotate, so as to ensure the stability and uniformity during the unwinding process of the non-woven fabric.

[0037] Specifically, a box body 17 is arranged outside the roller shaft side plate, an opening door 18 is arranged on the box body 17, and the belt pulley is arranged in the box body.

[0038] By arranging the driving system (belt pulley) in the box body, the influence of external factors on the driving system can be effectively prevented, and the safety is improved.

[0039] Specifically, a transition roller 19 is provided between the unwinding roller and the cloth discharging roller.

[0040] The presence of transition rollers makes the process from unwinding to cutting of nonwoven fabrics smoother, reducing the possibility of wrinkles and deviations. By properly setting the position and number of transition rollers, the tension of the nonwoven fabric can be better controlled to ensure cutting quality.
