Description

Technical Field

[0001] The utility model relates to the technical field of cutting tables, in particular to a cutting table device for fabric production based on improving cutting accuracy. Background Art

[0002] Fabric cutting machine is a kind of equipment specially designed for cutting fabrics. It is equipped with precise cutting tools and advanced control systems to ensure the accuracy and efficiency of the cutting process. The main function of this equipment is to accurately cut large pieces of fabric into the required shape and size according to the design requirements, thus laying a solid foundation for the subsequent sewing process.

[0003] Chinese patent CN217922754U discloses a fabric cutting table that is convenient for collecting waste from cutting school uniform fabrics. This technology belongs to the technical field of fabric cutting tables. Specifically, this patent realizes the convenient collection of cutting waste by setting up a frame structure. When it is necessary to collect and process the waste, the staff can control the extension of the electric telescopic rod to push the frame downward so that the brush plate is in close contact with the cutting table body. Subsequently, by controlling the cutting frame to move along the guide rail, the brush plate can effectively brush the waste on the surface of the cutting table body, ensuring that the waste falls smoothly into the collection box under the brushing action. This patent cuts the fabric by the reciprocating movement of the cutting frame and the reciprocating movement of the cutting knife.

[0004] The existing technology has certain problems in the cutting process. Specifically, the cutting frame moves forward and backward, while the cutting knife moves left and right to achieve the cutting of the fabric. During the cutting process, although the edge of the fabric is fixed by the fixing structure, as the cutting knife moves, the cut part of the fabric often pulls the uncut part, causing the cut part to deviate, thereby affecting the cutting accuracy.

DETAILED DESCRIPTION

[0024] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Reference Figure 1-Figure 6 As shown, the utility model provides a cutting bed device for fabric production based on improving cutting accuracy, including a frame 1, a support table assembly 11 installed at the center of the frame 1 for placing fabrics, and the support table assembly 11 is used to place the fabrics to be cut to ensure that the fabrics remain flat during the cutting process. A first moving mechanism 12 is arranged on both sides of the top of the frame 1, and a reciprocating moving frame 13 is arranged on the first moving mechanism 12. A cutting assembly 14 for cutting the fabrics is also arranged on the moving frame 13. The first moving mechanism 12 provides horizontal movement capability so that the cutting assembly 14 can move to different positions of the fabrics. Anti-deviation assemblies 15 for fixing the fabrics are also arranged on both sides of the moving frame 13. The anti-deviation assembly 15 includes a pressing plate 153 that can move up and down and contact the fabrics. The pressing plate 153 contacts the fabrics by moving up and down, and applies a certain pressure to fix the fabrics on the support table assembly 11 to prevent the fabrics from moving during cutting. The first moving mechanism 12 is started, driving the moving frame 13 to move back and forth in the horizontal direction, and the cutting assembly 14 on the moving frame 13 moves to the designated cutting position accordingly. The cutting assembly 14 is started to perform a precise cutting operation on the fabric.

[0026] When the fabric needs to be cut, the fabric is first placed on the support platform assembly 11. The pressing plate 153 of the anti-deviation assembly 15 contacts the fabric by moving up and down, fixing the fabric on the support platform assembly 11 to prevent the fabric from deviating during the cutting process.

[0027] The cutting assembly 14 includes a cutting knife 144 that can move up and down and reciprocate along the width direction of the fabric. The cutting knife 144 can move in the vertical direction so as to apply sufficient pressure to the fabric for cutting when it contacts the fabric. Two pressing plates 153 are arranged on both sides of the cutting knife 144, and a through groove is formed between the two pressing plates 153 for the cutting knife 144 to move.

[0028] The cutting component 14 and the anti-deviation component 15 can work together to ensure that the fabric remains fixed and stable during the cutting process, thereby achieving high-precision cutting.

[0029] The anti-deviating assembly 15 includes a mounting plate 151 fixed on the moving frame 13, and a second telescopic driving member 152 for moving the pressing plate 153 up and down is fixed on the top of the mounting plate 151. The output end of the second telescopic driving member 152 passes through the mounting plate 151 and is connected to a lifting plate 1521. Guide rods 1522 for guiding the lifting plate 1521 are also fixed on both sides of the top of the lifting plate 1521. The guide rods 1522 pass through the mounting plate 151 and extend to the top of the mounting plate 151.

[0030] Before the cutting operation begins, the second telescopic drive member 152 is in a shortened state, so that the lifting plate 1521 and the pressing plate 153 thereon are in a higher position and do not contact the fabric. When the fabric needs to be cut, the second telescopic drive member 152 begins to extend, driving the lifting plate 1521 and the pressing plate 153 to move downward. Due to the existence of the guide rod 1522, the movement of the lifting plate 1521 is stable and controlled. When the pressing plate 153 contacts the fabric, the pressing plate 153 will apply a certain amount of pressure to fix the fabric on the support platform assembly 11 to prevent the fabric from shifting during the cutting process.

[0031] The anti-deviance assembly 15 includes a limit rod 1531 fixed at both ends of the top of the pressure plate 153, and the limit rod 1531 is slidably connected to the lifting plate 1521. A return spring 154 is sleeved on the limit rod 1531, one end of the return spring 154 is fixedly connected to the top of the pressure plate 153, and the other end of the return spring 154 is fixedly connected to the lifting plate 1521.

[0032] refer to Figure 4-Figure 5As shown, the cutting assembly 14 includes a second moving mechanism 141 arranged in the moving frame 13 and used to drive the cutting knife 144 to reciprocate, the second moving mechanism 141 includes a second lead screw 1411 arranged along the length direction of the moving frame 13, the second moving mechanism 141 includes a second rotating driving member 1412 installed on the outside of the moving frame 13 and driving the second lead screw 1411 to rotate, a moving plate 1413 that moves along the length direction of the second lead screw 1411 is threadedly connected to the second lead screw 1411, and a first telescopic driving member 142 that drives the cutting knife 144 to move up and down is fixed to the top of the moving plate 1413, and the output end of the first telescopic driving member 142 is connected to the knife seat 143, and the knife seat 143 and the cutting knife 144 are detachably connected.

[0033] The first moving mechanism 12 includes a first lead screw 121 arranged along the length direction of the frame 1, and the first moving mechanism 12 includes a first rotating driving member 122 fixed on the frame 1, the output end of the first rotating driving member 122 is transmission-connected to the first lead screw 121, the first moving mechanism 12 includes a slide rail 123 arranged along the length direction of the first lead screw 121 and fixed on the top of the support platform assembly 11, the slide rail 123 is slidingly connected to the moving frame 13, and the moving frame 13 is threadedly connected to the first lead screw 121.

[0034] Driven by the first telescopic drive member 142, the knife seat 143 and the cutting knife 144 will move up and down. When the fabric needs to be cut, the first telescopic drive member 142 will drive the knife seat 143 and the cutting knife 144 to descend so that the cutting knife 144 contacts the fabric, and the second rotary drive member 1412 is started to drive the second lead screw 1411 to rotate. Since the movable plate 1413 is threadedly connected to the second lead screw 1411, the movable plate 1413 will move along its length direction as the second lead screw 1411 rotates. In this way, the first telescopic drive member 142 and the knife seat 143 (and the cutting knife 144 connected to the knife seat 143) fixed on the movable plate 1413 will also move accordingly, thereby realizing the reciprocating movement of the cutting knife 144 in the horizontal direction, refer to Figure 6 As shown, the support platform assembly 11 includes a support platform body 111 fixed on the frame 1, and a plurality of through holes 1111 for gas to pass through are opened on the support platform body 111. The support platform assembly 11 includes a connecting pipe 1112 and a negative pressure fan 1113. One end of the connecting pipe 1112 is connected to the negative pressure fan 1113, and the other end of the connecting pipe 1112 is connected to the bottom of the support platform body 111.

[0035] Before cutting, the fabric to be cut is placed on the support platform body 111. The negative pressure fan 1113 is started, and the negative pressure fan 1113 extracts the gas at the through hole 1111 on the support platform body 111 through the connecting pipe 1112 to form a negative pressure area. This negative pressure area will generate an adsorption force on the fabric, firmly adsorbing the fabric on the support platform body 111 to prevent it from deflecting during the cutting process.

[0036] Working principle: When in use, first place the fabric on the support platform body 111. Then start the negative pressure fan 1113. The suction force generated by the negative pressure fan 1113 causes the air inside the support platform body 111 to flow, and then the fabric is firmly adsorbed on the support platform body 111 through the through hole 1111. Next, the first screw 121 is driven to rotate by the first rotating drive member 122. The rotation of the first screw 121 drives the moving frame 13 to move, and then the cutting knife 144 moves to the position where the fabric needs to be cut. Then, start the second telescopic drive member 152, and the second telescopic drive member 152 pushes the lifting plate 1521 downward, thereby driving the pressing plate 153 to contact the surface of the fabric. In this process, the reset spring 154 plays a buffering role on the pressing plate 153 to ensure that the contact between the pressing plate 153 and the fabric is stable. At this time, start the first telescopic drive member 142, and the first telescopic drive member 142 pushes the knife seat 143 and the cutting knife 144 to contact the fabric. Then, the second rotary drive member 1412 is started, and the second rotary drive member 1412 drives the second lead screw 1411 to rotate, thereby driving the moving plate 1413 to move. Driven by the moving plate 1413, the cutting knife 144 cuts the fabric accurately.

[0037] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
