Description

Technical Field

[0001] The utility model relates to the technical field of cutting, in particular to a tarpaulin cutting device which can prevent wrinkles and deformation. Background Art

[0002] Tarpaulin is a kind of cloth used for shelter and protection, with the following characteristics: Diverse materials: usually made of materials with good weather resistance, such as polyester, nylon, canvas, etc. Waterproof performance: can effectively block rain and keep the interior dry. Windproof function: resist a certain degree of wind force, reducing the risk of the tent or shelter being blown down by the wind.

[0003] Tarpaulin cutting refers to the process of cutting and tailoring tarpaulins according to specific needs and designs. In the prior art, tarpaulin cutting needs to ensure its stable position, so a fixing component is often provided on the cutting device to fix it. However, the fixing component is generally installed on a placement plate component instead of being installed together with the cutting knife. Therefore, it has the following disadvantages when used: the fixing component and the cutting knife need to be operated separately, which increases the complexity and difficulty of the operation. When installing and disassembling the fixing component, time is wasted, affecting the overall work efficiency. The fixing and cutting actions cannot be completed at one time, resulting in reduced cutting accuracy. Separate operations increase the risk of accidental injury. In order to change the status quo, a tarpaulin cutting device that prevents wrinkles and deformation is proposed. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4A tarpaulin cutting device for preventing wrinkles and deformation comprises a bottom plate 1 and a hydraulic cylinder 2. The bottom plate 1 is used to place the tarpaulin and has a cutting groove on its upper end surface. The hydraulic cylinder 2 is installed on the top of the workshop.

[0022] The telescopic end of the hydraulic cylinder 2 is connected to a lifting frame 3, an insertion rod 4 is installed on the lifting frame 3, a fixed plate 6 is provided above the base plate 1, a fixed rod 5 is installed on the fixed plate 6, the insertion rod 4 is connected to the fixed rod 5 through an elastic mechanism, a double-sided rack 8 is provided below the lifting frame 3, a cutting knife 9 is provided on the double-sided rack 8 through a fixing mechanism, a smoothing roller 7 is provided above the base plate 1 through a mounting frame 11, the cutting knife 9 is connected to the mounting frame 11 through a movable mechanism, and the mounting frame 11 is connected to the double-sided rack 8 through a transmission mechanism.

[0023] The elastic mechanism includes an extrusion groove 15 arranged on the fixing rod 5, the insertion rod 4 is in the extrusion groove 15, and a spring 16 is elastically connected between the outer wall of the insertion rod 4 and the inner wall of the extrusion groove 15. When the spring 16 is compressed, the elastic potential energy provided realizes the extrusion of the fixing plate 6, thereby ensuring the stability of the fixing plate 6 when fixing the tarpaulin.

[0024] The fixing mechanism includes a connecting plate 10 connected to the double-sided rack 8 through a first bolt, and the connecting plate 10 is connected to the cutting knife 9 through a second bolt. As shown in the figure, the connecting plate 10 is L-shaped. The above-mentioned first bolt and second bolt realize a stable connection between the cutting knife 9 and the double-sided rack 8, as well as convenient disassembly and assembly between the two.

[0025] The movable mechanism includes a through rod 14 installed on the cutting knife 9. The two mounting frames 11 are connected by a connecting plate 13. The through rod 14 slides through the connecting plate 13 to prevent the mounting frame 11 and other components from being separated from the double-sided rack 8.

[0026] The transmission mechanism includes a gear 12 installed on the mounting frame 11, which is meshed with a double-sided rack 8. By means of the double-sided rack 8 and the gear 12, the mounting frame 11 is rotated relative to the connecting plate 13, thereby driving the smoothing roller 7 to move relative to the tarpaulin, thereby smoothing the tarpaulin.

[0027] The vertical cross-section of the extrusion groove 15 is T-shaped, and the vertical cross-section of the portion of the insertion rod 4 in the extrusion groove 15 is also T-shaped. The above-mentioned shape structure avoids the separation between the insertion rod 4 and the fixing rod 5.

[0028] When the utility model is used, the tarpaulin is placed on the base plate 1, and its cutting position corresponds to the cutting groove on the upper end surface of the base plate 1. Then the hydraulic cylinder 2 is started to drive the lifting frame 3 and other components to descend. First, the fixed plate 6 will contact the tarpaulin. During the subsequent descent of the lifting frame 3 and other components, the fixed plate 6 will stably press down and fix the tarpaulin. The spring 16 will be compressed, so the elastic potential energy provided by it ensures the downward pressing and fixing force of the fixed plate 6. During the continuous descent of the lifting frame 3 and other components, the smoothing roller 7 will first contact the tarpaulin, and then the double-sided rack 8 will descend relative to the gear 12 and drive the gear 12 to rotate. The gear 12 drives the mounting frame 11 and the smoothing roller 7 to rotate in an inclined state, and the inclination angle becomes larger and larger, thereby realizing the smoothing operation of the tarpaulin. Finally, the cutting knife 9 contacts the tarpaulin to realize the cutting process of the tarpaulin.

[0029] After cutting is completed, the hydraulic cylinder 2 contracts to drive the cutting knife 9 and other components to rise and separate from the tarpaulin. At this time, since the spring 16 is compressed and restored, the fixed plate 6 is separated from the tarpaulin later than the cutting knife 9, which effectively prevents the tarpaulin from adhering to the outer wall of the cutting knife 9 and rising with it.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
