Description

Technical Field

[0001] The utility model relates to the technical field of cloth processing, in particular to a cross-cutting device for a tarpaulin slitting machine. Background Art

[0002] In the tarpaulin production process, transverse cutting is a key process, especially when processing large areas of fabric. However, existing transverse cutting technology has some significant shortcomings, which seriously affect production safety and efficiency.

[0003] First, the blades used for horizontal cutting are often fully exposed, posing a significant safety hazard to workers during the cutting process. Due to the sharpness of the blades and the high speed of operation, any negligence could result in serious injuries. This safety hazard not only threatens worker health but can also lead to downtime and increased medical expenses, further impacting business operations and cost control.

[0004] Secondly, after the transverse cut is completed, the fabric tends to get stuck in the opening, causing a buildup. This buildup not only hinders the smooth progress of subsequent cutting processes but also causes excessive wear and tear on the equipment, leading to frequent failures and increased maintenance and replacement costs. Furthermore, the buildup of fabric can affect installation efficiency, extend production cycles, and reduce overall production efficiency.

[0005] In summary, the existing transverse cutting technology has obvious deficiencies in safety, efficiency and cost control. There is an urgent need for a new technology or equipment that can effectively solve these problems to improve production safety and efficiency and reduce unnecessary economic losses. Utility Model Content

[0006] The purpose of the utility model is to provide a cross-cutting device for a tarpaulin slitting machine, which has high continuous cutting efficiency and prevents the tarpaulin from getting stuck, in order to solve the above problems.

[0007] In order to achieve the above-mentioned purpose, the utility model discloses a cross-cutting device for a tarpaulin slitting machine, comprising a frame and a feeding device arranged on the frame, and is characterized in that: an anti-cloth shell is arranged on the rear side frame of the feeding device, and a pressing device is arranged near the rear end position of the anti-cloth shell, and a strip cut is arranged on the upper end surface of the anti-cloth shell on the front side of the pressing device, and the height of the horizontal plane where the plate body on the front side of the strip cut is higher than the height of the horizontal plane where the plate body on the rear side of the strip cut is, and a cutting knife body sliding along the strip cut is arranged on the frame below the anti-cloth shell.

[0008] After adopting the above structure, the height of the horizontal plane of the plate on the front side of the strip cut is higher than that on the back side. This design helps to guide the cloth to pass smoothly, reduce resistance and the risk of cloth jamming, and the cutting blade slides along the strip cut to achieve continuous and uniform cutting, thereby improving cutting quality and efficiency.

[0009] Preferably, the anti-cloth jam housing is a rectangular box structure composed of multiple baffles, and the rectangular box is arranged along the left and right directions of the frame and perpendicular to the cloth feed direction. The strip cut is arranged in the middle of the top plate of the anti-cloth jam housing along the length direction of the anti-cloth jam housing, and the baffle located in front of the strip cut is higher than the baffle located behind the strip cut, forming a table-like structure. The flat upper end surface of the rectangular box structure can effectively ensure the smooth movement and advancement of the cloth, while the table-like structure helps guide the cloth through smoothly, reducing resistance and the risk of cloth jam.

[0010] Preferably, the pressing device includes a third control cylinder disposed at the rear end of the anti-clogging cloth housing and near the left and right inner walls. The third control cylinder is disposed in a vertical direction, and a drive rod extends beyond the upper end surface of the anti-clogging cloth housing. The two drive rods are provided with pressing rods whose lengths match the length of the anti-clogging cloth housing. By providing the two drive rods with pressing rods whose lengths match the length of the anti-clogging cloth housing, the pressing device can accommodate fabrics of different widths, exhibiting strong versatility and adaptability. The design of the pressing device can also reduce slippage and deviation of the fabric during the cutting process.

[0011] Preferably, the cutting blade body includes a horizontally mounted slide rail on a frame, a slider mounted on the slide rail, and a cutting blade holder mounted on the slider rail. A brushless electric shears with a front baffle extending from a strip-shaped cutting edge is mounted above the cutting blade holder, and the middle portion of the cutting blade holder is fixed to the slider rail. A drive device is mounted on the frame below the cutting blade holder to drive the cutting blade holder along the slide rail. The combination of the slide rail and the slider ensures that the cutting blade holder can slide stably along the slide rail, improving cutting stability and precision. The brushless electric shears design reduces the potential for harm to the human body caused by conventional cutting tools during the cutting process, thereby improving operational safety.

[0012] Preferably, the driving device includes a driving motor arranged at the left end of the frame and a tensioning pulley arranged at the right end of the frame corresponding to the driving motor, a synchronous belt connecting the driving shaft of the driving motor and the tensioning pulley is arranged between the two, and a positioning plate vertical to the cutting blade holder and connected to the synchronous belt is provided at the lower part of the cutting blade holder.

[0013] Preferably, an L-shaped stopper plate is provided at the top of the cutting blade holder, extending from a strip-shaped cutout and cooperating with the brushless electric shears. The lower portion of the vertical plate of the L-shaped stopper plate is fixed to the cutting blade holder, and the horizontal plate is positioned directly above and in close contact with the upper blade body of the brushless electric shears. The L-shaped stopper plate effectively prevents injury to workers and enables the upper end of the brushless electric shears to complete the cloth cutting operation along the strip-shaped cutout. The positioning plate can be fixed to the timing belt via bolts or clips, allowing the cutting blade to slide along the strip-shaped cutout, achieving continuous and uniform cutting.

[0014] Preferably, the feeding device includes two support seats respectively arranged on the left and right sides of the upper part of the bracket in the vertical direction, and a cloth feeding roller and a cloth pressing roller are arranged between the two support seats in the vertical direction. The cloth feeding roller is located below the cloth pressing roller and the upper end of the support seat is provided with a first control cylinder for controlling the cloth pressing roller to move up and down in the vertical direction.

[0015] To sum up, the beneficial effects of the present invention are: when the cloth is placed on a plane, the present invention has high continuous cutting efficiency and can prevent cloth jamming and reduce the operating risks of the staff. The height of the horizontal plane of the plate on the front side of the strip cut is higher than that on the back side. This design helps to guide the cloth to pass smoothly, reduce resistance and the risk of cloth jamming, and the cutting blade slides along the strip cut to achieve continuous and uniform cutting, thereby improving the cutting quality and efficiency.
