Description

Technical Field

[0001] The present invention relates to the technical field of cloth cutting, and in particular to a textile cloth cutting device and method based on pressing and adjusting position. Background Art

[0002] The cloth cutting machine uses a micro motor to drive the gears to rotate and make the blade move up and down to achieve the effect of cutting multiple layers of cloth.

[0003] A cutting platform for fabric processing is disclosed in Chinese patent publication number CN218521513U, which includes: a cutting table, on which a discharge roller for releasing fabric to be cut and a mounting plate are fixed; a material conveying mechanism, which is arranged on the mounting plate and is used to convey the fabric to be cut; a measuring mechanism, which is arranged on the cutting table and is used to measure the required cutting length; a cutting mechanism, which is arranged on the mounting plate and is used to cut the measured fabric; the cutting platform has a simple structure and is easy to use. The fabric to be cut is first loaded onto the discharge roller, and then the measuring mechanism is set to determine the cutting length. The fabric is conveyed through the material conveying mechanism. After being conveyed to the set length, the fabric is pressed and cut through the cutting mechanism. The operation is simple and easy to use, and the problem of fabric bending during cutting is effectively avoided, thereby ensuring cutting accuracy.

[0004] Regarding the question of how to release the fabric in its initial state, first, you need to put the fabric under the feed roller (at this time, the feed roller is not pressed down). Because the feed roller can only move in the vertical direction, in order to allow the feed roller to press the fabric for feeding, you need to make the front edge of the fabric placed under the feed roller exceed the downward pressure line of the feed roller (the line that intersects with the table or fabric when it is in contact). In this way, after the feed roller moves down, it can act on the fabric, and then feed the fabric to the cutting side through its own rotation.

[0005] However, the cloth is a flexible material, and it is easy to bend during the manual insertion process. The downward pressure line formed by the transfer roller, which can only move up and down, cannot form a pulling force to straighten the bent cloth. It can only be pressed up, causing creases in the cloth. If it is smoothed manually, there must be enough space under the transfer roller, so the moving range of the transfer roller must be increased. Summary of the invention

[0006] The object of the present invention is to provide a textile fabric cutting device and method based on a press-adjusted position, so as to solve the problem of how to make a lower pressure line form a pulling force in the lateral direction.

[0007] To achieve the above-mentioned object, one of the objects of the present invention is to provide a textile fabric cutting device based on a press-adjustable position, which is mounted on a workbench, the cutting device comprising a cutting member and a feeding member, the cutting member being mounted on the workbench in a manner perpendicular to a fabric feeding route, the feeding member being arranged on one side of the cutting member, and the feeding member comprising at least:

[0008] A load-bearing end, the load-bearing end being fixed to one of the workbench and the cutting member;

The closest distance between the rotation point and the table surface on the base plane is shorter than the distance between the rotation point and the farthest point of the driving feed roller, so that when the driving feed roller rotates, the arc path formed and the straight line where the table surface is located in the base plane form two intersection points, and the lower pressing line moves horizontally between the two intersection points;

[0012] The driving feed roller is a flexible structure.

[0016] As a further improvement of the technical solution, the pressing plate includes a first plate body and a second plate body, and a feed roller frame is provided at the end of the second plate body, and the feed roller frame is used to carry a feed roller group;

[0017] The first plate body and the second plate body are rotatably connected to the first support portion at the corners thereof;

[0018] The bearing end is a support provided on both sides of the pressing plate, the support has a first support portion, and is rotatably connected to the pressing plate through the first support portion, and a second support portion extends upward from one side of the support close to the cutting member, and an intermediate plate is rotatably connected to the second support portion;

[0019] A torsion spring is arranged between the middle plate and the second supporting part, and an elastic telescopic rod is arranged between the first plate body and the workbench, wherein:

[0020] The torsion spring provides a force to the middle plate to rotate it clockwise;

[0021] The elastic telescopic rod provides a force to the pressing plate to make it rotate counterclockwise;

[0022] A lower pressing plate is arranged on one side of the cutting top seat close to the middle plate.

[0023] As a further improvement of the technical solution, the feed roller group has three feed rollers, namely a first feed roller, a second feed roller and a third feed roller, and the first feed roller, the second feed roller and the third feed roller are arranged in sequence from a side close to the feed member to a side away from the feed member;

[0024] The first feed roller, the second feed roller and the third feed roller are all rotatably connected to the feed roller frame. A driving motor is arranged axially on the first feed roller.

[0026] As a further improvement of the technical solution, the lower pressure line of the first feed roller finally stops at the foot of a vertical line passing through the rotation point and perpendicular to the table surface during the movement between the two points, so as to drive the cloth to feed toward the feeding component side.

[0027] As a further improvement of the technical solution, when the lower pressure line of the first feed roller is at the vertical foot position, the lowest points of the first feed roller and the second feed roller are at the same height, and the third feed roller is separated from the table surface.

[0030] Step 2: Using the plane perpendicular to the axis of the rotation point as the base plane, the feed roller is driven to rotate under the drive of the pressing plate, and then an arc path is formed on the base plane;

[0031] Step 3: The table top of the workbench forms a straight line on the base surface, and the arc-shaped path intersects with the straight line to form two intersection points.

After entering the second stage, the first feed roller and the second feed roller are tilted upward, and the third feed roller is in contact with the fabric.

[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0058] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0059] Regarding the question of how to release the fabric in its initial state, first, you need to put the fabric under the feed roller (at this time, the feed roller is not pressed down). Because the feed roller can only move in the vertical direction, in order to allow the feed roller to press the fabric for feeding, you need to make the front edge of the fabric placed under the feed roller exceed the downward pressure line of the feed roller (the line that intersects with the table or fabric when it is in contact). In this way, after the feed roller moves down, it can act on the fabric, and then feed the fabric to the cutting side through its own rotation.

[0060] However, the cloth is a flexible material, and it is easy to bend during the manual insertion process. The downward pressure line formed by the transfer roller, which can only move up and down, cannot form a pulling force to straighten the bent cloth. It can only be pressed up, causing creases in the cloth. If it is smoothed manually, there must be enough space under the transfer roller, so the moving range of the transfer roller must be increased.

[0061] To this end, the present invention provides a textile fabric cutting device based on a press-adjustable position to solve the problem of how to make the lower pressure line form a pulling force in the lateral direction, such as Figure 1 As shown, the cutting device is mounted on a workbench 100, and specifically includes a cutting component 200 and a feeding component 300. The cutting component 200 is installed on the workbench 100 in a manner perpendicular to the cloth feeding route, and the feeding component 300 is arranged on one side of the cutting component 200, specifically on the same side as a roller (not shown in the figure) on the workbench 100 on which the cloth is rolled. Then the feeding component 300 uses friction to drive the cloth to feed toward the feeding component 300 side, and forms the above-mentioned feeding route.

[0062] The above is a common structure of a cutting device in the art, and the following embodiments disclose the points that the present invention intends to protect.

[0063] The first embodiment, as Figure 2 As shown, the feeding member 300 includes a pressing plate 310 and a bearing end, the pressing plate 310 is rotatably connected to the bearing end, and the pressing plate 310 is fixed to the workbench 100 or the cutting member 200 through the bearing end. A feeding roller group is provided at the lower end of the pressing plate 310, and the feeding roller group has at least one feeding roller for driving the cloth, and the feeding roller driving the cloth contacts the cloth to form a lower pressure line. Before the cloth is fed, the feeding rollers in the feeding roller group are all separated from the workbench 100 table surface. Because the feeding rollers are required to stably press the cloth, in this embodiment, the pressing plate 310 is rotatably connected to the bearing end. The connected axes form a rotation point, and the plane perpendicular to the axis is used as the base plane. The closest distance between the rotation point and the table surface on the base plane is shorter than the distance between the rotation point and the farthest point of the driving feed roller (the driving feed roller refers to the feeding roller that drives the cloth). In this way, the feeding roller is driven to rotate under the drive of the pressing plate 310, and an arc path is formed. The arc path has two intersections with the table surface, and the two intersections respectively represent the starting point and the end point of the change in the horizontal position of the lower pressure line. At this time, it is only necessary to place the front edge of the cloth beyond the starting point (the standard of exceeding here means being closer to the cutting component 200 than the starting point).

[0064] Preferably, see Figure 6As shown, the bearing ends in this embodiment are two supports 340, and the two supports 340 are respectively arranged on both sides of the pressing plate 310, and then the pressing plate 310 is rotatably connected with the first support portion 341 on the support 340, and a motor (not shown in the figure) is installed at the first support portion 341 as a power source to drive the pressing plate 310 to rotate, and the feed roller group in this embodiment has only one first feed roller 321, and the first feed roller 321 rotates under the action of the driving motor installed in its axial direction, so that the driving feed roller is formed by the first feed roller 321. Fig.14 The principle of changing the position of the lower pressure line is shown as follows:

[0065] First, it is determined that the distance between the rotation point and the farthest point of the first feed roller 321 is represented by R, and the vertical distance between the rotation point and the table surface (that is, the shortest distance) is represented by D. Then, the first feed roller 321 rotates under the drive of the pressing plate 310 and forms an arc path. On the base surface, the arc path is the arc L2 obtained by rotating with the rotation point as the center and R as the radius. Then, the table surface is represented by a straight line L1 on the base surface. Because R>D, L2 will have two intersection points P1 and P2 with L1. At this time, in the extended three-dimensional space, P1 and P2 are the points on the lower pressure line formed when the first feed roller 321 fits the table surface.

[0066] It should be noted that, because the first feed roller 321 is a flexible structure, the first feed roller 321 will be squeezed and deformed by the table surface in the space between P1 and P2, and then come into surface contact with the table surface. Because this contact surface is not wide, generally 0.2-0.4 cm (in order to intuitively show that there is a certain distance between P1 and P2 in the figure, a certain amount of magnification is performed, which is not used as a basis for protection), so the contact surface can be regarded as a downward pressure line, that is, as the pressing plate 310 rotates, the downward pressure line moves toward P2 with P1 as the starting point. During the movement of the downward pressure line, the foot of the perpendicular line passing through the rotation point and perpendicular to L1 is the position where the deformation of the first feed roller 321 is the largest, which means that at this position, the contact area between the downward pressure line of the first feed roller 321 and the cloth is the largest, so the friction force formed is also the largest, which is most suitable for driving the cloth to feed toward the feeding component 300 side.

[0067] Moreover, because the starting point of the change in the position of the lower pressure line is at P1, there is no need to push the cloth to the above-mentioned vertical foot at this time. Just put the front edge of the cloth at P1, preferably beyond P1, so that the cloth is moved to the vertical foot or beyond the vertical foot under the pressure of the first feed roller 321, thereby realizing an adjustment of the cloth position. The whole process is a pulling of the cloth, and then it reaches the specified position. The bending of the cloth is avoided during the pulling process, thereby preventing creases in the cloth caused by squeezing.

[0068] For further information, see Figure 2 and Figure 3 As shown, the cutting component 200 includes a cutting base 210 and a cutting top base 220. The cutting top base 220 is installed on the cutting base 210, and a cutter 221 is arranged below it. A first hydraulic rod 222 is arranged above the cutting top base 220. The cutter 221 moves up and down under the drive of the first hydraulic rod 222, and then a cutting groove 210A is opened through the cutting base 210. During the downward movement, the cutter 221 passes through the cutting groove 210A to cut the cloth below it.

[0069] Further, if Figure 7 As shown, a first lifting body 250 is arranged between the cutting base 210 and the workbench 100. When the first lifting body 250 is lifted, a first working space 200A is formed between the cutting base 210 and the workbench 100. A second lifting body 260 is arranged between the cutting top seat 220 and the cutting base 210. When the second lifting body 260 is lifted, a second working space 200B is formed between the cutting top seat 220 and the cutting base 210. The formation of the first working space 200A and the second working space 200B makes it more convenient for the staff to inspect and repair the equipment or parts in the corresponding space.

[0070] For details, see Figure 4 and Figure 5 As shown, the first lifting body 250 includes a lower platform 251, a first upper connecting plate 252 and a second hydraulic rod 253. The lower platform 251 is fixed on the workbench 100, the first upper connecting plate 252 is fixed on the cutting base 210, and the second hydraulic rod 253 is mounted on the lower platform 251. The piston rod of the second hydraulic rod 253 is connected to the first upper connecting plate 252. Through the action of the piston rod of the second hydraulic rod 253, the first upper connecting plate 252 is pushed to drive the cutting base 210 to be lifted relative to the workbench 100.

[0071] The second lifting body 260 includes a third hydraulic rod 261 and a second upper connecting plate 262. The third hydraulic rod 261 is fixed in the cutting base 210. The piston rod of the third hydraulic rod 261 is connected to the second upper connecting plate 262. Under the push of the piston rod of the third hydraulic rod 261, the second upper connecting plate 262 drives the cutting top seat 220 to be lifted relative to the cutting base 210.

[0072] The second embodiment, as Figure 6 As shown, this embodiment discloses another rotation method of the pressing plate 310, which specifically cooperates with the cutting base 210 and the cutting top seat 220 to work. First, the pressing plate 310 is still rotatably connected to the first support portion 341, but is not driven by the motor. Fig.11As shown, in this embodiment, the pressing plate 310 includes a first plate body 310a and a second plate body 310b, the first plate body 310a and the second plate body 310b constitute the main body of the pressing plate 310, the second plate body 310b is used to carry the feed roller group, and considering that the feed roller group may be provided with a plurality of feed rollers, a feed roller frame 320 is provided at the end of the second plate body 310b, and then the feed roller rotates on the feed roller frame 320, wherein the driving motor for driving the feed roller is also installed on the feed roller frame 320. The first plate 310a and the second plate 310b are rotatably connected to the first support portion 341 at the corners. In addition, a second support portion 342 extends upward from the side of the support 340 close to the cutting member 200, and the second support portion 342 is rotatably connected to the middle plate 330. Specifically, a torsion spring 331 is provided between the middle plate 330 and the second support portion 342, and an elastic telescopic rod 311 is provided between the first plate 310a and the workbench 100, wherein:

[0073] The torsion spring 331 provides a force to the middle plate 330 to rotate it clockwise;

[0074] The elastic telescopic rod 311 provides a force to the pressing plate 310 to rotate counterclockwise.

[0075] Moreover, a lower pressing plate 240 is provided on one side of the cutting top seat 220 near the middle plate 330. When working, the first working space 200A and the second working space 200B are both in an open state, so that the staff can see the current status of the main equipment or parts before the device is operated to ensure the normal operation of the device. That is to say, before each operation of the device, the first working space 200A and the second working space 200B can be used to expose the main equipment or parts, and the feed rollers are off the table at this time. Next, take the first feed roller 321 as an example. In the first stage of operation, Figure 8 As shown, the cutting top seat 220 is lowered relative to the cutting base 210, that is, the piston rod of the third hydraulic rod 261 is reset. At the same time, the lower pressure plate 240 will also contact with the middle plate 330 and press the middle plate 330. The second plate body 310b is pried by the lever principle to rotate clockwise, thereby allowing the first feed roller 321 to drive the cloth to adjust its position. The specific principle has been explained in the first embodiment and will not be repeated here.

[0076] In the above embodiment, the cutting base 210 does not need to be lowered.

[0077] Further, another implementation of this embodiment is disclosed, such as Fig.11As shown, in the present embodiment, the feed roller group has three feed rollers, namely the first feed roller 321, the second feed roller 322 and the third feed roller 323, and the first feed roller 321, the second feed roller 322 and the third feed roller 323 are arranged in sequence from the side close to the feed member 300 to the side away from the feed member 300, and the first feed roller 321, the second feed roller 322 and the third feed roller 323 are all rotatably connected to the feed roller frame 320, except that a driving motor is arranged on the axial direction of the first feed roller 321, so that it constitutes a driven feed roller.

[0078] Also, see Figure 2 As shown, a pressure roller frame 231 is arranged below the cutting base 210, and a first pressure roller 230 is rotatably connected to the pressure roller frame 231. A pressure roller motor 232 is arranged on the axial direction of the first pressure roller 230. The first pressure roller 230 is driven by the pressure roller motor 232 to rotate on the pressure roller frame 231. At this time, the first feeding roller 321 in the first stage is required to feed the cloth to a position exceeding the first pressure roller 230, and then enter the second stage, the cutting base 210 moves downward, and drives the lower pressure plate 240 to continue to move downward, that is, Figure 11-Figure 12 As shown by the arrow in a, Fig. 9 As shown, at this time, the lower pressing plate 240 presses the middle plate 330 to rotate counterclockwise, that is, Figure 11-Figure 12 In the direction indicated by the arrow b, the middle plate 330 pries the second plate 310b and rotates clockwise. Figure 11-Figure 12 As shown by the arrow c, it should be noted that since the main body formed by the first plate 310a and the second plate 310b is a bent structure, the first plate 310a cannot be effectively subjected to force due to insufficient distance during the second stage of prying. For this reason, a convex body 310c is provided on the side of the first plate 310a close to the middle plate 330 to compensate for the distance. In this way, under the prying of the middle plate 330, the first feed roller 321 can be separated from the cloth, and at this time, the first pressing roller 230 is in contact with the cloth because the cutting base 210 moves downward, so the subsequent cloth is fed driven by the first pressing roller 230.

[0079] Considering that after the first feeding roller 321 is separated, the subsequent feeding of the cloth cannot be continuous. Fig.13 As shown, a first pressing roller 230 and a second pressing roller 233 are respectively mounted on both sides of the cutting groove 210A. Since the two have the same structure, they will not be described here in detail. In this way, after the first feeding roller 321 leaves the table, the second pressing roller 233 ensures the feeding of subsequent fabrics, while the first pressing roller 230 completes the feeding of the fabric after cutting.

[0080] It should be noted that, see Fig.11As shown, in this embodiment, when the lower pressure line of the first feed roller 321 is at the vertical foot position, the lowest points of the first feed roller 321 and the second feed roller 322 are at the same height, so that under the downward pressure of the second feed roller 322, the cloth will not be rolled onto the first feed roller 321, and the third feed roller 323 is separated from the table surface at this time. After entering the second stage, as shown in FIG. Fig.12 As shown, the first feeding roller 321 and the second feeding roller 322 are tilted upward, and the third feeding roller 323 is in contact with the cloth.

[0081] In addition, see Fig.10 As shown, two limiting plates 110 are symmetrically arranged on the side of the workbench 100 where the cloth enters. The two limiting plates 110 limit the cloth and form a clamping groove 100B between the workbench 100 to provide an independent activity space for the elastic telescopic rod 311. In addition, a reserved groove 100A is opened on the workbench 100 to provide activity space for the driving motor.

[0082] The present invention also provides a cutting method for a textile cloth cutting device, which comprises the following method steps:

[0083] Step 1: The pressing plate 310 rotates on the load-bearing end, and a rotation point is formed at the rotation connection between the pressing plate 310 and the load-bearing end;

[0084] Step 2: Using the plane perpendicular to the axis of the rotation point as the base plane, the feed roller is driven to rotate under the drive of the pressing plate 310, and then an arc path is formed on the base plane;

[0085] Step 3: The table surface of the workbench 100 forms a straight line on the base surface, and the arc-shaped path intersects with the straight line to form two intersection points. During the rotation process, the lower pressure line of the driving feed roller moves laterally between the two intersection points.
