Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and particularly relates to a multi-directional cutting equipment for fireproof canvas. Background Art

[0002] Fireproof canvas is a relatively thick cotton or linen fabric with good waterproof and fireproof properties, and is commonly used in tent canvas, shielding canvas, etc. Since fireproof canvas is usually used in large-area sheets and there are few curved cuts during the cutting process. Therefore, most of the existing cutting equipment for fireproof canvas uses relatively fixed cutting wheels, and uses feeding rollers to transport the fireproof canvas, and then uses the cutting wheels to perform straight cutting on the fireproof canvas.

[0003] When cutting the end of the fireproof canvas, it is usually necessary to perform oblique cutting so that during actual sewing processing, corresponding bevels or thickened surfaces can be formed, and these bevels and thickened surfaces are usually used for punching or positioning during production. However, the existing cutting equipment cannot achieve the function of oblique cutting when cutting the end of the fireproof canvas, but instead cuts according to the specified oblique direction manually, resulting in a problem of reduced cutting efficiency. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a multi-directional cutting equipment for fireproof canvas, which can achieve multi-directional cutting, especially oblique cutting at the end of the canvas, so as to improve the processing efficiency.

[0012] Furthermore, the cutting member includes a workbench, the sliding member is arranged on the top surface of the workbench, and a cutting vertical knife is arranged on the side surface of the workbench along one side of the guiding sliding direction of the sliding member.

DETAILED DESCRIPTION OF THE INVENTION

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Terms such as "upper", "inner", "middle", "left", "right", and "one" cited in this specification are only for the convenience of description and are not used to limit the scope of implementation of the present invention. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present invention.

[0025] Referring to Figures 1 to 5 As shown, a multi-directional cutting device for fireproof canvas includes a working platform 1 for placing the fireproof canvas. A chute 11 is provided at the edge of the top surface of the working platform 1. A moving block 2 is slidably connected to the chute 11. The number of moving blocks 2 is multiple. A sliding limiting member is provided between the moving block 2 and the chute 11. The same guiding rod 3 is detachably connected between any two moving blocks 2. A cutting member is provided on the top surface of the working platform 1. A sliding member is provided on the top surface of the cutting member. The sliding member is slidably adapted to the guiding rod 3.

[0026] Specifically, the purpose of the present invention is to achieve multi-directional cutting, especially to perform oblique cutting on the end of the canvas, so as to improve the processing efficiency. Therefore, by slidably arranging a plurality of moving blocks 2 on the edge of the top surface of the working platform 1, by sliding the moving blocks 2, the connection line between two of the moving blocks 2 can be adjusted to coincide with or be parallel to the required cutting trajectory, and then it is convenient to detachably install the same guiding rod 3 between these two moving blocks 2. Then, by using the sliding connection between the sliding member of the cutting member and the guiding rod 3, when the cutting member moves along the length direction of the guiding rod 3, the fireproof canvas can be cut at the same time. Thus, by moving any two moving blocks 2, the length direction of the guiding rod 3 between these two moving blocks 2 is made to be consistent with the straight or oblique cutting direction required during cutting, and then the cutting member enables the cutting member to achieve the function of multi-directional cutting. Compared with the prior art in which only straight cutting can be achieved by using a relatively fixed cutting wheel, and oblique cutting needs to be carried out manually, the present invention has the beneficial effects of being able to achieve multi-directional cutting and improving the processing efficiency.

[0027] Referring to Figures 1 to 5As shown, the plane of the working platform 1 is square, specifically rectangular. The sliding grooves 11 are opened at the four edge positions of the top surface of the working platform 1, thus forming four non - communicating sliding grooves 11. Each sliding groove 11 is slidably connected to a corresponding moving block 2. Specifically, by defining the shape of the working platform 1, it is mainly to facilitate the staff to better move and adjust the corresponding moving block 2, so that the guide rod 3 between two of the moving blocks 2 coincides with or is parallel to the required cutting and trimming trajectory. For example, when straight cutting is required, the two opposite moving blocks 2 on the working platform 1 are adjusted so that these two moving blocks 2 face each other and correspond to the drawing trajectory on the canvas; when oblique cutting is required, the two adjacent moving blocks 2 on the working platform 1 are adjusted, so that the guide rod 3 between these two moving blocks 2 coincides with or is parallel to the drawing trajectory on the canvas.

[0028] In order to disclose the structure of the sliding limiting member, so as to realize the function of using the sliding limiting block to limit the sliding connection of the moving block 2 on the sliding groove 11, and at the same time improve the connection stability of the moving block 2 on the sliding groove 11. The cross - section of the sliding groove 11 is in an inverted T - shape. The sliding limiting member includes a sliding nut 12 slidably connected to the inner bottom groove of the sliding groove 11. Both side surfaces of the moving block 2 opposite to each other along the length direction of the sliding groove 11 are fixedly connected with fixing blocks 21. A connecting hole 22 is penetrated through the end surface of the fixing block 21 facing the sliding groove 11. A limiting screw rod 23 is threadedly connected to the connecting hole 22, and the end of the limiting screw rod 23 is threadedly connected to the sliding nut 12.

[0029] When the moving block 2 slides to a suitable position and it is necessary to limit the continuous sliding of the moving block 2, after the limiting screw rod 23 is threadedly penetrated through the connecting hole 22 and threadedly connected to the sliding nut 12, due to the sliding limiting effect of the sliding nut 12 on the inner wall of the inner bottom groove of the sliding groove 11, the sliding nut 12 moves upward, and the end of the limiting screw rod 23 moves towards the inner bottom surface of the sliding groove 11 until the sliding nut 12 abuts against the top wall of the inner bottom groove of the sliding groove 11 and the end of the limiting screw rod 23 abuts against the inner bottom surface of the sliding groove 11. Thus, the function of limiting and fixing the sliding of the moving block 2 on the sliding groove 11 is realized.

[0030] During the cutting and trimming process, not all four moving blocks 2 on the working platform 1 are needed, and sometimes some of the moving blocks 2 are idle. To reduce the situation where the idle moving blocks 2 obstruct the actual cutting space. A strip-shaped block 27 is fixedly connected to the bottom surface of the moving block 2. The length direction of the strip-shaped block 27 is consistent with the length direction of the sliding groove 11. The moving block 2 is inserted and slid with the sliding groove 11 through the strip-shaped block 27. Therefore, when some of the moving blocks 2 on the working platform 1 are idle, after releasing the threaded connection state of the limit screw 23 and the sliding nut 12, the strip-shaped block 27 of the moving block 2 can be separated from the sliding groove 11, so as to move the corresponding moving block 2 out of the working platform 1, thereby improving the operating space.

[0031] To facilitate placing the guide rod 3 on the top surface of the moving block 2 to accommodate guide rods 3 of different lengths, and at the same time, when moving adjacent moving blocks 2, it is not necessary to take out the guide rod 3, and the function of adjusting the length direction position of the guide rod 3 can also be realized. A rotating hole 24 is opened on the top surface of the moving block 2. A rotating rod 25 is rotatably connected to the rotating hole 24. The end of the rotating rod 25 far from the rotating hole 24 is fixedly connected with a U-shaped limit block 26. The U-shaped opening of the U-shaped limit block 26 faces away from the side of the moving block 2. The U-shaped opening of the U-shaped limit block 26 is used for placing the guide rod 3. It can be seen that since the U-shaped limit block 26 is rotatably connected to the top surface of the moving block 2, when the guide rod 3 is placed in the U-shaped openings of the U-shaped limit blocks 26 of two moving blocks 2 at the same time, during the process of moving the moving block 2, the movable pair formed by the rotation connection of the U-shaped limit block 26 and the rotating hole 24 can be utilized to realize the function of automatically adjusting the length direction position of the guide rod 3.

[0032] To realize the function of detachably connecting and fixing the guide rod 3 with two U-shaped limit blocks 26, so as to reduce the situation where the guide rod 3 falls off during the process of the cutting piece moving along the length direction of the guide rod 3. A threaded portion 31 is provided on the outer peripheral surface of the guide rod 3. Hand-tightening nuts are threadedly connected to both ends of the guide rod 3. When the guide rod 3 is inserted into the U-shaped limit blocks 26 on the top surfaces of any two moving blocks 2, the two hand-tightening nuts of the guide rod 3 move threadedly towards each other until the hand-tightening nuts abut against the U-shaped limit blocks 26, thereby realizing the function of fixing the guide rod 3.

[0033] Refer to Figures 1 to 5 As shown, to disclose the structure of the cutting piece, so as to realize the cutting and trimming function. The cutting piece includes a workbench 4. A sliding member is arranged on the top surface of the workbench 4. A cutting vertical knife 41 is arranged on the side surface of the workbench 4 along one side of the guiding sliding direction of the sliding member. Therefore, when the workbench 4 moves along the length direction of the guide rod 3 through the sliding member, the fireproof canvas is cut by the cutting vertical knife 41 at the same time.

[0034] In order to disclose the structure of the sliding member, so as to realize the function that the workbench 4 is slidably connected to the guide rod 3 by means of the sliding member. The sliding member includes a U-shaped slider 43. Both ends of the U-shaped slider 43 along the direction of its U-shaped opening are fixedly connected with connecting pieces 44. The connecting pieces 44 are penetrated with straight holes 45. Assembly holes 42 are formed on the top surface of the workbench 4. The straight holes 45 of the connecting pieces 44 are locked and connected to the assembly holes 42 by screws. The U-shaped opening of the U-shaped slider 43 faces the workbench 4. The U-shaped opening of the U-shaped slider 43 is for the insertion of the guide rod 3, so that the moving block 2 is slidably connected to the guide rod 3 through the U-shaped opening of the U-shaped slider 43.

[0035] Since the sliding movement of the moving block 2 is adjusted manually and the corresponding length direction of the guide rod 3 is judged to correspond to the drawing track on the canvas manually, in order to reduce the error caused by manual operation. An installation opening 46 is formed at the top position of the side surface of the workbench 4 where the cutting vertical knife 41 is located. A strip-shaped rod 5 is inserted into the installation opening 46. Part of the strip-shaped rod 5 is inserted into the installation opening 46. A through hole 51 is penetrated through the top surface of the strip-shaped rod 5 on the side away from the installation opening 46. A touch pen 52 is inserted into the through hole 51. The tip of the touch pen 52 faces downward. An installation hole 47 is formed on the top surface of the workbench 4. The installation hole 47 is communicated with the installation opening 46. The installation hole 47 is threadedly connected with a pressing bolt. When fixing the strip-shaped rod 5, by tightening the pressing bolt, the end of the pressing bolt presses the strip-shaped rod 5. At the same time, when carrying out the cutting work, the position of the through hole 51 can be adjusted, so that the tip of the touch pen 52 abuts against the drawing on the canvas. Thus, it is possible to judge whether there is coincidence or deviation between the touch pen 52 and the drawing on the canvas, and further realize the function of facilitating the judgment of the cutting error.

[0036] Special note: In this embodiment, the number of the installation holes 47 is two. The two installation holes 47 are arranged on both sides of the cutting vertical knife 41 respectively, so as to facilitate the adjustment of the position of the strip-shaped rod 5 and at the same time avoid the use of the cutting vertical knife 41 to improve the operation space.

[0037] In order to further improve the function of the pressing bolt to fix the strip-shaped rod stably. A sinking groove 53 is formed on the top surface of the end of the strip-shaped rod 5 located in the installation opening 46. A damping block 54 is fixedly connected in the sinking groove 53. Therefore, when it is necessary to fix the strip-shaped rod 5, by tightening the pressing bolt, the end of the pressing bolt abuts against the damping block 54 on the top of the strip-shaped rod 5, so as to realize the function of improving the stability.

[0038] The implementation manners of the present invention are not limited thereto. According to the above content of the present invention, using the common general technical knowledge and conventional means in the art, without departing from the above basic technical idea of the present invention, the present invention can also be modified, replaced or combined in other various forms, all of which fall within the scope of the protection of the rights of the present invention.
