Anti-slip positioning structure for fabrics used in cutting tables

Abstract

The present invention relates to a fabric anti-slip positioning structure for a cutting table, comprising a base, a U-shaped base mounted on the left end of the base, a rotating block rotatably mounted on the outer side wall of the U-shaped base, a temporary pressing mechanism mounted on the upper end of the rotating block, a rack mounted on the rotating block, the rack meshing with a rack plate, the rack plate mounted on a sliding base, a main cylinder connected between the sliding base and the right end of the base, a reversible anti-slip positioning mechanism mounted on the sliding base, and a pressing mechanism for pressing the anti-slip positioning mechanism mounted on the upper end of the sliding base. The present invention can solve the problem of manually pressing a clamp when the fabric to be cut is superimposed on a fabric layer, and then placing the fabric to be cut on top of the fabric layer. Since the fabric has a certain degree of bulkiness, the thickness of the fabric layer will instantly swell and increase when it is not clamped. At this time, the fabric layer may fall over or deviate from its position due to the expansion of its thickness.

Description

Technical Field

[0001] The present invention relates to the technical field related to clamping and positioning, and in particular to a cloth anti-slip positioning structure for a cutting table. Background Art

[0002] Fabric is a commonly used material in decorative materials. It can be seen everywhere in our daily life and plays an important role. People's lives are inseparable from fabrics. Fabrics need to be cut when they are used. Cutting requires the help of a cutting table. The cutting table is an automatic cutting device used in the textile and clothing, leather industry, car seat, and furniture industry. Clothing cutting is an important link in ensuring clothing quality. When the cutting table cuts the fabric, the fabric needs to be clamped and fixed. The existing clamping method mainly clamps and positions the fabric layer by manually pressing the clip. However, the existing clamping method often encounters some defects in actual use:

[0003] When the cloth to be cut is superimposed on the cloth layer (which has been cut), it is necessary to manually press the clip to open the clip, and then place the cloth to be cut on top of the cloth layer. However, since the cloth has a certain degree of fluffiness, the thickness of the cloth layer will instantly swell and increase when it is not clamped. At this time, the cloth layer may fall over or deviate from its position due to the expansion of the thickness. For the misaligned cloth layer, the personnel need to align and sort it out again, which reduces the efficiency of the cloth cutting work.

[0004] Therefore, there is an urgent need for a cutting table cloth anti-slip positioning structure to solve the above-mentioned defects. Summary of the Invention

[0005] 1. Technical Solution

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fabric anti-slip positioning structure for a cutting table, comprising a base, a U-shaped seat is installed at the left end of the base, a rotating block is rotatably provided on the outer side wall of the U-shaped seat, a temporary pressing mechanism is installed at the upper end of the rotating block, a rack is provided on the rotating block, the rack is meshed with the rack plate, the rack plate is installed on the sliding seat, a main cylinder is connected between the sliding seat and the right end of the base, a flippable anti-slip positioning mechanism is provided on the sliding seat, and a pressing mechanism for pressing the anti-slip positioning mechanism is installed at the upper end of the sliding seat.

[0007] The anti-slip positioning mechanism includes an angle plate, an angle block, a return spring, a return telescopic rod, a pressing piece, an active positioning assembly, a driven positioning assembly and a clamping assembly, wherein one end of the angle plate is connected to the sliding seat by a pin, and a return spring is connected between the angle plate and the bottom of the sliding seat, and the other end of the angle plate is installed at the angle block, and the return telescopic rod is connected between the angle block and the pressing piece, and the return spring and the return telescopic rod both play the role of elastic reset. The number of pressing pieces is three, and an active positioning assembly is provided on the pressing piece located in the middle, and corresponding driven positioning assemblies are respectively provided inside the pressing pieces located on both sides, and the active positioning assembly and the driven positioning assembly are linked together. Hidden grooves are provided at the front and rear ends of the angle block, and a clamping assembly is provided in the hidden groove. The clamping assembly is temporarily clamped with the clamping groove provided on the U-shaped seat. The setting of the anti-slip positioning mechanism is only used for anti-falling positioning of the cloth layer. The specific movement method is as follows: when the cloth to be cut is located at the upper end surface of the angle block (the cloth layer is positioned by the pressing piece, active positioning assembly and driven positioning assembly under the angle block). At this time, it is necessary to overlap the fabric to be cut with the fabric layer. The overlapping process is as follows: the main cylinder drives the sliding seat and the anti-slip positioning mechanism to move outward (away from the fabric) as a whole. The moving process is divided into a forward and backward journey. In the first half of the journey, due to the temporary engagement of the clamping assembly with the clamping groove, the angle block slides out horizontally. At this time, since there is fabric laid flat on the top of the angle block, the horizontal sliding of the angle block prevents the edge of the fabric from flipping. In the second half of the journey, the angle block is separated from the fabric, and the clamping assembly is disengaged from the clamping groove. Under the action of the return spring, the angle plate and the angle block are adjusted upward (open state). The upward-opening angle block facilitates the subsequent inward movement of the pressing member, the active positioning assembly, and the driven positioning assembly to be above the fabric layer. If the angle block is not opened upward, but moves inward horizontally, the lower ends of the pressing member, the active positioning assembly, and the driven positioning assembly will directly touch the edge of the fabric layer, thereby squeezing and folding the edge position, and thus failing to reach the upper position of the fabric layer for pressing and positioning.

[0008] Preferably, the temporary pressing mechanism includes a shrinkage frame, a compression spring and a pressing piece. The lower end of the shrinkage frame is installed on the upper end of the rotating block. A T-shaped pressing piece is slidingly provided inside the shrinkage frame, and a compression spring is connected between the pressing piece and the shrinkage frame.

[0009] Under the elastic action of the compression spring, the pressing piece always maintains a tendency to extend outward. During the downward angle adjustment process of the shrinking frame, the pressing piece temporarily compresses the top layer of fabric and the fabric layer under the action of the compression spring. As the shrinking frame continues to be adjusted downward in angle and the compression spring is compressed, the pressing force of the pressing piece gradually increases.

[0010] Preferably, the active positioning component includes a built-in cylinder, an extrusion plate, an extrusion rod, a built-in spring, an extrusion frame, a positioning piece and a spring. A movable groove is provided inside the pressing piece located in the middle, and a built-in cylinder is installed at the upper end of the movable groove. The ejection end of the built-in cylinder is installed at the extrusion plate. The extrusion rod that is extruded with the extrusion plate is slidably arranged on the side end of the pressing piece. A built-in spring is connected between the extrusion rod and the movable groove. The extrusion frame corresponding to the position of the extrusion plate is slidably arranged in the movable groove. The lower end surface of the extrusion frame with an inverted T-shaped structure is evenly installed with a positioning piece, and a spring is connected between the extrusion frame and the movable groove. The built-in spring and the spring together play the role of elastic reset.

[0011] Preferably, the extrusion plate consists of a plate body and a ball bearing. A rollable ball bearing is provided on the side end of the plate body. The ball bearing contacts the inclined surface of the extrusion rod. The provision of the ball bearing reduces the extrusion resistance with the inclined surface of the extrusion rod.

[0012] Preferably, the driven positioning assembly includes a pressure rod, a connecting spring, an extrusion block, a linkage frame, a second positioning member, and a second spring. Corresponding linkage grooves are respectively opened inside the pressing members on both sides. A pressure rod is slidingly provided at the upper end of the linkage groove. A connecting spring is connected between the pressure rod and the linkage groove. An extrusion block is provided at the lower end of the pressure rod. A linkage frame cooperating with the extrusion block is slidably provided on the linkage groove. The second positioning member is evenly installed at the lower end of the linkage frame. A second spring is connected between the linkage frame and the linkage groove. The connecting spring and the second spring play a role of elastic reset.

[0013] Preferably, a rotating squeezing roller is provided at the upper end of the linkage frame, and the squeezing roller contacts the inclined surface of the squeezing block, and the squeezing roller reduces the squeezing resistance with the inclined surface of the squeezing block.

[0014] Preferably, the clamping assembly includes a clamping block and a push spring. The clamping block is slidably arranged in the hidden groove. A push spring is connected between the clamping block and the hidden groove. The push spring plays a role of elastic reset.

[0015] Preferably, the pressing mechanism includes a pressing cylinder, a pressing roller, a limiting contact point and a connecting frame. The connecting frame is installed at the upper end of the sliding seat. The upper end of the connecting frame is installed with a pressing cylinder, the lower end of the pressing cylinder is installed with a pressing roller, and the limiting contact point is installed on the upper left end of the connecting frame. The limiting contact point plays the role of limiting the upper end angle during the upward angle adjustment process of the angle block.

[0016] Preferably, a supporting rod is provided at the lower end of the angle plate, and the supporting rod serves to support the lower end of the angle plate, and the sliding seat is slidably provided on the base.

[0017] 2. Beneficial Effects

[0018] 1. The present invention discloses a fabric anti-slip positioning structure for a cutting table. This application adopts a design concept of structural linkage. When the anti-slip positioning mechanism exits (the clamp is opened), the temporary clamping mechanism is synchronously adjusted in angle, thereby timely clamping and locking the topmost layer of fabric and the fabric layer, so that the fabric layer is always in a compressed state, avoiding the situation where the fabric layer is tilted or deviated due to fluffiness. In addition, for fabric cutting, a multi-integrated positioning structure of a pressing part, an active positioning component, and a driven positioning component is used to prevent the fabric from slipping before cutting, thereby improving the clamping degree.

[0019] 2. In the fabric anti-slip positioning structure for a cutting table described in the present invention, the temporary pressing mechanism and the anti-slip positioning mechanism rotate in opposite directions, so that the temporary pressing mechanism and the anti-slip positioning mechanism always press the fabric in a "one-or-the-other" manner, and the coordinated rotation between the temporary pressing mechanism and the anti-slip positioning mechanism is mainly achieved by the meshing cooperation between the rack and the rack plate;

[0020] 3. The anti-slip positioning structure for fabric on a cutting table described in the present invention has a two-stage movement when the anti-slip positioning mechanism exits (exits from between the topmost layer of fabric and the fabric layer). The first half of the exit is in horizontal sliding, ensuring that the exit does not affect the superposition between the topmost layer of fabric and the fabric layer. After exiting the gap between the topmost layer of fabric and the fabric layer, the anti-slip positioning mechanism is adjusted upward at an elastic action. At this time, the height of the pressing part, the active positioning assembly, and the driven positioning assembly is greatly increased, ensuring that when the subsequent sliding seat moves to the initial position, the pressing part, the active positioning assembly, and the driven positioning assembly are above the fabric layer. Under the downward squeezing of the pressing mechanism, the pressing part, the active positioning assembly, and the driven positioning assembly can successfully press and position the fabric layer (the topmost layer of fabric and the fabric layer have been successfully merged and superimposed).

[0030] The embodiments of the present invention are described below with reference to the accompanying drawings. In the process, to ensure clarity and convenience of the description, we may exaggerate the width of the lines or the size of the components in the drawings.

[0031] In addition, the following terms are defined based on the functions of the present invention and may vary depending on the intentions or practices of the user or operator. Therefore, these terms are defined based on the entire content of this specification.

[0032] like Figures 1 to 8 As shown, a fabric anti-slip positioning structure for a cutting table includes a base 1, a U-shaped seat 2 is installed at the left end of the base 1, a rotating block 3 is rotatably provided on the outer side wall of the U-shaped seat 2, a temporary pressing mechanism 4 is installed at the upper end of the rotating block 3, a rack 5 is provided on the rotating block 3, the rack 5 is meshed with a rack plate 6, the rack plate 6 is installed on a sliding seat 7, a main cylinder 8 is connected between the sliding seat 7 and the right end of the base 1, a flippable anti-slip positioning mechanism 9 is provided on the sliding seat 7, and a pressing mechanism 10 for pressing the anti-slip positioning mechanism 9 is installed at the upper end of the sliding seat 7.

[0033] The anti-slip positioning mechanism 9 includes an angle plate 91, an angle block 92, a return spring 93, a return telescopic rod 94, a pressing piece 95, an active positioning component 96, a driven positioning component 97 and a clamping component 98. One end of the angle plate 91 is connected to the sliding seat 7 by a pin shaft. A return spring 93 is connected between the angle plate 91 and the bottom of the sliding seat 7. The other end of the angle plate 91 is installed on the angle block 92. A return telescopic rod 94 is connected between the angle block 92 and the pressing piece 95. The return spring 93 and the return telescopic rod 94 both play a role of elastic reset. The number of the pressing pieces 95 is three, and the pressing piece located in the middle An active positioning component 96 is provided on 95, and corresponding driven positioning components 97 are respectively provided inside the pressing pieces 95 on both sides, and the active positioning components 96 and the driven positioning components 97 are linked together. Hidden grooves are provided at the front and rear ends of the angle block 92, and a clamping component 98 is provided in the hidden groove. The clamping component 98 is temporarily clamped with the clamping groove 11 provided in the U-shaped seat 2. The setting of the anti-slip positioning mechanism 9 is only used to prevent the fabric layer from falling off. The specific movement mode is as follows: when the fabric to be cut is located on the upper end surface of the angle block 92 (the fabric layer is clamped by the pressing piece 95 and the active positioning component below the angle block 92), the fabric layer is clamped by the pressing piece 95 and the active positioning component below the angle block 92). 96, driven positioning assembly 97 is positioned), at this time, the cloth to be cut needs to be superimposed with the cloth layer, and the superposition process is as follows: the main cylinder 8 drives the sliding seat 7 and the anti-slip positioning mechanism 9 to move outward as a whole (away from the cloth). The moving process is divided into a front and back journey. In the first half of the journey, due to the temporary engagement of the clamping assembly 98 with the clamping groove 11, the angle block 92 slides out horizontally. At this time, since the cloth is laid flat on the top of the angle block 92, the horizontal sliding of the angle block 92 avoids the situation where the edge of the cloth flips. In the second half of the journey, the angle block 92 is separated from the cloth, and the clamping assembly 98 is in contact with the clamping groove 11. 1, under the action of the return spring 93, the angle plate 91 and the angle block 92 are adjusted to an upward angle (open state), and the angle block 92 opened to an upward angle is conducive to the subsequent inward movement of the pressing member 95, the active positioning component 96, and the driven positioning component 97 to be above the fabric layer. If the angle block 92 is not opened to an upward angle, but moves inward in a horizontal state, the lower ends of the pressing member 95, the active positioning component 96, and the driven positioning component 97 will directly touch the edge of the fabric layer, thereby squeezing and folding the edge position, and thus cannot reach the upper position of the fabric layer for pressing and positioning.

[0034] During specific operation, the base 1 is installed at a suitable position on the existing cutting table, and the uncut cloth is spread flat on the cutting table (the cloth after this application is at the upper end of the angle block 92 at this time). After spreading, the main cylinder 8 drives the sliding seat 7 and the anti-slip positioning mechanism 9 to move away from the cloth as a whole (the movement trajectory of the angle block 92 is to first exit horizontally and then open at an upward angle). At the same time, with the help of the cooperation between the rack 5 and the rack plate 6, the temporary pressing mechanism 4 is driven to adjust the angle downward until the upper end surface of the cloth is pressed (the cloth originally located at the upper end of the angle block 92 is in direct contact with the cloth layer below after the angle block 92 is withdrawn horizontally), and the superimposed cloth is temporarily pressed by the temporary pressing mechanism 4 (at the same time as the angle block 92 is withdrawn The fabric is pressed tightly at the same time, so as to avoid affecting the follow-up movement of other fabrics when the angle block 92 is withdrawn). Subsequently, the main cylinder 8 drives the sliding seat 7 to reset in the opposite direction. At this time, the temporary pressing mechanism 4 is gradually adjusted to an upward angle. When the sliding seat 7 moves to the initial position, the pressing mechanism 10 descends, thereby pressing the angle block 92 adjusted to an upward angle until the clamping assembly 98 is re-engaged with the clamping groove 11. At this time, the pressing piece 95, the active positioning assembly 96, and the driven positioning assembly 97 are used to fit and prevent slipping of the top layer of fabric and the fabric / cutting bed below. Subsequently, one end of the top layer of fabric is cut by the cutting bed to obtain a single piece of fabric, which is neatly stacked with the fabric below. After the pieces of cloth are positioned and cut, the present application is designed to solve the problem of cloth superposition. First, the cut and superimposed cloth is prevented from falling off and positioned by the pressing piece 95, the active positioning component 96, and the driven positioning component 97. At this time, the cloth to be cut is located on the upper end surface of the angle block 92. Subsequently, when the cloth to be cut is superimposed with the cut cloth below, the angle block 92, the pressing piece 95, the active positioning component 96, and the driven positioning component 97 are withdrawn horizontally. When withdrawing, the cloth is temporarily positioned by the temporary pressing mechanism 4 to prevent the cloth from shifting together with the withdrawn components and causing position deviation of the cloth. With the smooth withdrawal of the angle block 92, the pressing piece 95, the active positioning component 96, and the driven positioning component 97, After the fabric to be cut is superimposed and overlapped with the cut fabric below (the temporary pressing mechanism 4 temporarily positions it), the angle block 92, the pressing piece 95, the active positioning component 96, and the driven positioning component 97 are reset as a whole. The reset angle block 92, the pressing piece 95, the active positioning component 96, and the driven positioning component 97 are located above the fabric layer. Under the pressure of the pressing mechanism 10, the fabric layer is prevented from falling off and positioned, and then the top layer of fabric is cut. The present application temporarily positions the fabric when the top layer of fabric is superimposed with the fabric layer below, thereby avoiding the deviation of the fabric position. After the top layer of fabric is superimposed with the fabric layer, the anti-falling positioning is performed to avoid the tilting and deviation of the edge of the gradually thickening fabric layer.

[0035] In another embodiment provided by the present invention, further, the temporary clamping mechanism 4 includes a shrinking frame 41, a compression spring 42 and a clamping member 43, the lower end of the shrinking frame 41 is installed on the upper end of the rotating block 3, and the interior of the shrinking frame 41 is slidingly provided with a T-shaped clamping member 43, and a compression spring 42 is connected between the clamping member 43 and the shrinking frame 41.

[0036] Under the elastic action of the compression spring 42, the pressing piece 43 always maintains a tendency to extend outward. During the downward angle adjustment process of the shrinking frame 41, the pressing piece 43 temporarily compresses the top layer of fabric and the fabric layer under the action of the compression spring 42. As the shrinking frame 41 continues to be adjusted downward in angle and the compression of the compression spring 42, the pressing force of the pressing piece 43 gradually increases.

[0037] Furthermore, the active positioning assembly 96 includes a built-in cylinder 961, an extrusion plate 962, an extrusion rod 963, a built-in spring 964, an extrusion frame 965, a positioning member 966 and a spring 967. A movable groove is provided inside the pressing member 95 in the middle. The upper end of the movable groove is provided with a built-in cylinder 961. The ejection end of the built-in cylinder 961 is provided with an extrusion plate 962. The extrusion rod 963, which is extruded and matched with the extrusion plate 962, is slidably provided at the side end of the pressing member 95. A built-in spring 96 is connected between the extrusion rod 963 and the movable groove. 4. The extrusion frame 965 corresponding to the position of the extrusion plate 962 is slidably set in the movable groove. The lower end surface of the extrusion frame 965 with an inverted T-shaped structure is evenly installed with a positioning member 966, and a spring 967 is connected between the extrusion frame 965 and the movable groove. The built-in spring 964 and the spring 967 play a role of elastic reset. The extrusion plate 962 is composed of a plate body and a ball. A rollable ball is set at the side end of the plate body. The ball contacts the inclined surface of the extrusion rod 963. The setting of the ball reduces the extrusion resistance with the inclined surface of the extrusion rod 963.

[0038] Furthermore, the driven positioning assembly 97 includes a pressure rod 971, a connecting spring 972, an extrusion block 973, a linkage frame 974, a second positioning member 975, and a second spring 976. Corresponding linkage grooves are respectively provided inside the pressing members 95 on both sides. A pressure rod 971 is slidingly provided at the upper end of the linkage groove. A connecting spring 972 is connected between the pressure rod 971 and the linkage groove. An extrusion block 973 is provided at the lower end of the pressure rod 971. A linkage frame 974 cooperating with the extrusion block 973 is slidably provided on the linkage groove. A second positioning member 975 is evenly installed at the lower end of the linkage frame 974. A second spring 976 is connected between the linkage frame 974 and the linkage groove. The connecting spring 972 and the second spring 976 play a role of elastic reset. A rotating extrusion roller is provided at the upper end of the linkage frame 974. The extrusion roller contacts the inclined surface of the extrusion block 973. The extrusion roller reduces the extrusion resistance with the inclined surface of the extrusion block 973.

[0039] Specifically, when the pressing piece 95 is pressed on the top of the fabric layer (at this time, the fabric to be cut and the fabric layer below are already stacked together), the extrusion plate 962 is driven to descend by the built-in cylinder 961. During the descent, both sides of the extrusion plate 962 squeeze the extrusion rod 963. The squeezed extrusion rod 963 contacts the pressure rod 971 and moves outward synchronously. The synchronously moving extrusion block 973 squeezes the linkage frame 974 to descend, and the descending positioning piece 975 further prevents the fabric layer from falling off. At the same time, after the descending extrusion plate 962 descends for a distance (the distance is the same as the distance between the extrusion rod 963 and the initial position), the extrusion plate 962 is lowered. 63, the spacing between the pressure rods 971 is equal) contacts the extrusion frame 965, and then the two are synchronously lowered, thereby driving the positioning member 1 966 to lower, and then the fabric layer is prevented from falling off and positioned. The fabric layer is multi-positioned by the pressing member 95 and the descending positioning member 1 966 and the positioning member 2 975. When the anti-slip positioning mechanism 9 moves horizontally, the extrusion plate 962 is driven to rise by the built-in cylinder 961. Under elastic reset, the positioning member 1 966 and the positioning member 2 975 rise and separate from the fabric layer. The small area contact between the pressing member 95 and the fabric layer will not hinder the pressing member 95 from moving outward.

[0040] Furthermore, the clamping assembly 98 includes a clamping block 981 and a push spring 982. The clamping block 981 is slidably set in the hidden groove. A push spring 982 is connected between the clamping block 981 and the hidden groove. The push spring 982 plays a role of elastic reset.

[0041] Specifically, during the process of the anti-slip positioning mechanism 9 moving outward, in the first half of the journey, under the temporary engagement of the engaging block 981 and the engaging groove 11, the angle block 92 slides horizontally and is withdrawn. In the second half of the journey, the engaging block 981 is separated from the engaging groove 11, and under the action of the return spring 93, the angle plate 91 and the angle block 92 are adjusted upward. After the top layer of fabric and the fabric layer are superimposed together, the sliding seat 7 moves horizontally inward (at this time, the angle plate 91, the angle block 92, the pressing piece 95, the active positioning component 96, and the driven positioning component 97 are adjusted upward). When it moves to the initial position, the pressing mechanism 10 lowers the angle plate 91 so that the angle plate 91 is rearranged horizontally. At this time, the engaging block 981 is re-engaged in the engaging groove 11, and the fabric layer is anti-slip positioned by the pressing piece 95, the active positioning component 96, and the driven positioning component 97.

[0042] Furthermore, the pressing mechanism 10 includes a pressing cylinder 101, a pressing roller 102, a limiting contact point 103 and a connecting frame 104. The connecting frame 104 is installed on the upper end of the sliding seat 7. The upper end of the connecting frame 104 is installed with the pressing cylinder 101, the lower end of the pressing cylinder 101 is installed with the pressing roller 102, and the limiting contact point 103 is installed on the upper left end of the connecting frame 104. The limiting contact point 103 plays the role of upper end angle limitation during the upward angle adjustment process of the angle block 92.

[0043] Specifically, before the anti-slip positioning mechanism 9 moves outward, the pressing cylinder 101 drives the pressing roller 102 to rise to the highest position, thereby avoiding blocking the upward angle adjustment trajectory of the anti-slip positioning mechanism 9 during the outward movement. After the anti-slip positioning mechanism 9 moves to the innermost side, the pressing cylinder 101 drives the pressing roller 102 to descend, thereby adjusting the anti-slip positioning mechanism 9 that has been adjusted upward in angle downward, until the clamping block 981 is re-clamped in the clamping groove 11. At this time, the angle plate 91 and the angle block 92 are arranged horizontally.

[0044] Furthermore, a supporting rod is provided at the lower end of the angle plate 91 , and the supporting rod serves to support the lower end of the angle plate 91 , and the sliding seat 7 is slidably provided on the base 1 .

[0045] Working process:

[0046] Step 1: Install the base 1 at a suitable location on the existing cutting table;

[0047] Step 2: Lay the uncut cloth flat on the cutting table (the cloth is on the top layer and located at the upper end of the angle block 92, and the cloth layer is located below the angle block 92). After laying it flat, the main cylinder 8 drives the sliding seat 7 and the anti-slip positioning mechanism 9 to move outward as a whole. Under the meshing cooperation of the rack 5 and the rack plate 6, the temporary pressing mechanism 4 is adjusted downward. After the anti-slip positioning mechanism 9 exits from between the uncut cloth and the cloth layer, the temporary pressing mechanism 4 with the downward adjustment angle combines and stacks the uncut cloth and the cloth layer and temporarily presses and positions them. The anti-slip positioning mechanism 9 that moves outward is adjusted upward after exiting horizontally.

[0048] Step 3: The main cylinder 8 then drives the sliding seat 7 to move inward (close to the cloth), and the anti-slip positioning mechanism 9 with upward angle adjustment moves synchronously until the sliding seat 7 moves to the initial position. At this time, the anti-slip positioning mechanism 9 is located above the cloth layer (the uncut cloth and the cloth layer are combined and stacked). Then, the pressing cylinder 101 drives the pressing roller 102 to descend, thereby adjusting the anti-slip positioning mechanism 9 with upward angle adjustment downward until the clamping block 981 is re-engaged in the clamping groove 11. At this time, the pressing member 95 presses the cloth layer, and then the active positioning component 96 and the driven positioning component 97 cooperate to further prevent the cloth layer from falling off.

[0049] Step 4: Then, one end of the top layer of fabric is cut by a cutting machine to obtain a single piece of fabric, which is neatly stacked with the fabric below;

[0050] Step 5: Repeat steps 2 to 4 to position and cut the subsequent fabrics into pieces.

[0051] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
