Description

Technical Field

[0001] The invention relates to the field of cloth processing equipment, and in particular to a textile cloth edge pressing and cutting device. Background Art

[0002] Textile fabrics are classified into two categories according to the weaving method: weft knitted fabrics and warp knitted fabrics. After the weaving process of textile fabrics is completed, they usually need to be cut according to the production size requirements, such as cutting the uneven edges of the fabric.

[0003] At present, the fabric is generally cut by a cutting machine. The cutting machine is suitable for the segmentation and cutting of fabrics and other materials in various industries. It does not require any molds and is controlled by system software (setting the path to drive the cutter head to move and cut along this path), and then directly cuts the product.

[0004] However, when traditional textile fabric cutting devices are cutting the edges of fabric, on the one hand, it is difficult to press the edges of fabric tightly, which makes the fabric easily warp up, thus affecting the cutting accuracy; on the other hand, the reference line for cutting the edges needs to be measured manually and the edge parameters need to be input into the equipment. For batch fabric processing technology, the above process is relatively cumbersome.

[0005] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

[0006] In view of the above-mentioned defects, the purpose of the present invention is to provide a textile fabric edge pressing and cutting device, which can press and position the fabric to be cut while also detecting the edge notch position to quickly divide the cutting space and facilitate the next step of cutting.

[0007] In order to achieve the above-mentioned purpose, the present invention provides a textile fabric edge pressing and cutting device, including a transmission structure for directionally conveying materials and supporting the materials during the cutting process, a cutting drive structure equipped with a cutting knife and driving it to cut the materials along a predetermined trajectory, and a cutting positioning structure for positioning the materials before cutting; the cutting positioning structure includes a movable bracket perpendicular to the material conveying direction and moving on both sides, and a plurality of pressure wheels rotatably mounted on the movable bracket; the plurality of pressure wheels are distributed along the conveying direction; each of the pressure wheels can independently rotate within a predetermined angle; in the process of positioning the materials, the two groups of movable brackets are driven to move from the center to both sides, and in the process of moving, the resistance between the materials and the pressure wheels drives the pressure wheels to rotate to a first angle position; when the pressure wheels are out of contact with the materials, the pressure wheels rotate to a second angle position by themselves.

[0008] According to the textile fabric edge pressing and cutting device of the present invention, the movable bracket is driven by a telescopic device to move.

[0009] According to the textile fabric edge pressing and cutting device of the present invention, a support shaft for mounting a pressure wheel is provided on the movable bracket; a plurality of pressure wheels are mounted on the support shaft.

[0010] According to the textile fabric edge pressing and cutting device of the present invention, the pressure wheel is installed on the supporting shaft through a resetter; the resetter includes an inner ring and an outer ring which are mutually sleeved and can rotate relatively; an elastic member which generates a reset driving force for the pressure wheel is connected between the inner ring and the outer ring.

[0011] According to the textile fabric edge pressing and cutting device of the present invention, the pressing wheel is mounted on the supporting shaft in a concentric manner.

[0012] According to the textile fabric edge pressing and cutting device of the present invention, the pressing wheel is installed on the supporting shaft in an eccentric manner.

[0013] According to the textile fabric edge pressing and cutting device of the present invention, the support shaft is driven by a driving member to rotate; when the two groups of movable brackets move to the middle position, the support shaft drives the pressure wheel to rotate; and when the two groups of movable brackets move to the middle position, the support shaft drives the pressure wheel to rotate.

The present invention can press and position the fabric to be cut while also detecting the edge gap position, so as to quickly divide the cutting space and facilitate the next step of cutting.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] See also Figure 1 The present invention provides a textile fabric edge pressing and cutting device, which includes a transmission structure for directional transmission of materials and supporting the materials during the cutting process, a cutting drive structure equipped with a cutter 1 and driving it to cut the materials along a predetermined trajectory, and a cutting positioning structure for positioning the materials before cutting.

[0023] The transmission structure includes a conveyor belt 61, a plurality of conveyor rollers 62 driving the conveyor belt 61 to transmit, and a support platform 63 arranged in the cutting space to support the conveyor belt 61. Among them, at least one group of conveyor rollers 62 is used as a driving roller and is connected to a driver (a driving motor is sufficient). During operation, for example, after the previous batch of materials (cloth) is cut, the plurality of conveyor rollers 62 drive the conveyor belt 61 to transmit, and during the transmission process, the next batch of materials is driven to the cutting space corresponding to the support platform 63. The above transmission structure can form an automated feeding process to reduce manual intervention.

[0024] The cutting drive structure includes a first drive bracket 71 slidably mounted on the base 00 and moving along the X-axis direction (the X-axis direction is the transmission direction of the material), and a second drive bracket 72 slidably mounted on the first drive bracket 71 and moving along the Y-axis direction (the Y-axis direction is perpendicular to the transmission direction of the material); the cutting knife 1 is mounted on the second drive bracket 72. The present application utilizes the combined movement of the first drive bracket 71 and the second drive bracket 72 to drive the cutting knife 1 to perform cutting along a preset trajectory (the above-mentioned cutting drive structure is cited as prior art, which is not the innovation point of the present application, so it is only briefly described).

[0025] See also Figure 1 and Figure 2 The cutting positioning structure includes a mobile bracket 2 which is perpendicular to the material conveying direction and moves to both sides, and a plurality of clamping wheels 3 which are rotatably mounted on the mobile bracket 2; the mobile bracket 2 can be moved by being driven by a telescope or other driving structure, wherein the telescope can be a cylinder or a hydraulic cylinder; the plurality of clamping wheels 3 are distributed along the conveying direction.

[0026] During the process of pressing and positioning the cloth (at this time, the material to be cut has been moved into the cutting space), first, the two groups of mobile brackets 2 move relatively to the middle position, and then the pressing wheel 3 comes into contact with the material (the specific working process of the pressing wheel 3 will be described in detail below). Finally, the two groups of mobile brackets 2 move from the middle position to the predetermined positions on both sides. During the movement of the mobile brackets 2, the material is flattened, and after the movement of the mobile brackets 2 is completed, the material is pressed and positioned.

[0027] Each of the pressure wheels 3 can independently rotate within a predetermined angle, wherein the rotation of the pressure wheel 3 is used to detect the edge notch position closest to the center position of the material (cloth), and the reference line for edge cutting is determined by the edge notch position; during the movement of the movable bracket 2, the resistance between the material and the pressure wheel 3 drives the pressure wheel 3 to rotate to the first angle position.

[0028] When the pinch wheel 3 is out of contact with the material, the pinch wheel 3 rotates to the second angle position. At this time, the moment when part of the pinch wheel 3 is out of contact with the material indicates that the edge gap position is detected. At this time, the mobile bracket 2 stops moving. At this time, the two groups of mobile brackets 2 plan the cutting space (the edge line of the pinch wheel 3 has determined the cutting edge position).

[0029] See also Figure 3 and Figure 4The specific installation of the above-mentioned clamping wheel 3 is as follows: a support shaft 21 for mounting the clamping wheel 3 is provided on the movable bracket 2; multiple clamping wheels 3 are mounted on the support shaft 21. The clamping wheel 3 is mounted on the support shaft 21 through a resetter; the resetter includes an inner ring 41 and an outer ring 42 which are sleeved and relatively rotatable with each other, the inner ring 41 is fixedly connected or positionedly connected with the support shaft 21 (the inner ring 41 and the support shaft 21 are rotationally positioned and installed, for example, connected by splines), and the outer ring 42 is fixedly connected with the clamping wheel 3; an elastic member 43 that generates a reset driving force for the clamping wheel 3 is connected between the inner ring 41 and the outer ring 42. In this embodiment, the elastic member 43 is a torsion spring. Of course, other elastic member structures, such as a straight spring, etc., can also be selected.

[0030] The clamping wheel 3 is mounted on the support shaft 21 in a concentric or eccentric manner. In the present embodiment, the clamping wheel 3 is mounted on the support shaft 21 in an eccentric manner, and the support shaft 21 is driven by a driving member (such as a motor) to rotate.

[0031] Based on the above structure, during the process of pressing and positioning the cloth, the driving state of the pressing wheel 3 is that when the two groups of movable brackets 2 move to the middle position, the support shaft 21 drives the pressing wheel 3 to rotate, so that the pressing wheel 3 has a distance H from the bottom (conveyor belt 61 or support platform 63) to facilitate the passage of materials.

[0032] When the two groups of movable brackets 2 move to the middle position, the support shaft 21 drives the clamping wheel 3 to rotate, but because the material already exists below, the support shaft 21 rotates to the initial position but the clamping wheel 3 does not rotate to the initial position. In this state, the elastic member 43 deforms and tends to release (providing a rebound force for the clamping wheel 3 to return to its initial state).

[0033] When the pressing wheel 3 moves to the cloth gap position and breaks contact with the material, the elastic member 43 drives the pressing wheel 3 to return to the initial state due to the loss of the material blocking.

[0034] A pressure sensor 5 is provided on the mobile bracket 2 corresponding to each position of the pressure wheel 3; when the pressure wheel 3 enters the second angle position (in the present embodiment, the elastic member 43 drives the pressure wheel 3 to reset to the initial state), the pressure sensor 5 is triggered, and at this time the pressure sensor 5 sends a feedback signal to the control console to drive the mobile bracket 2 to stop moving.

[0035] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
