Description

Technical Field

[0001] This invention relates to the field of fabric cutting and feeding technology, and in particular to a fabric cutting and feeding device. Background Technology

[0002] Jewish hats are usually made of fabrics such as fleece, wool, or cotton. During the hat-making process, the fabric needs to be cut. First, the rolled fabric is placed on a special workbench. Then, an infrared positioning device projects positioning infrared rays onto the workbench to assist in the fabric spreading and position calibration. Next, the workers unfold the fabric and lay it flat on the workbench. Finally, the fabric is cut along a preset path using a guide rail cutting device.

[0003] The above method of confirming the cutting position by projecting infrared light and then manually laying out the fabric for cutting has some drawbacks. First, the fabric is prone to shifting or sliding during the manual laying process, making it difficult to guarantee the length accuracy of the laid fabric, thus affecting the cutting accuracy. Second, the manual intervention is more than one step, which not only increases the labor intensity but also reduces the cutting efficiency, making it difficult to achieve large-scale, continuous production.

[0004] To address the aforementioned problems, this application proposes a fabric cutting and feeding device. Summary of the Invention

[0005] This invention proposes a fabric cutting and feeding device, which solves the problems in related technologies where manual feeding is prone to deviation or slippage, affecting cutting accuracy, and involves many manual intervention steps, resulting in high labor intensity, low efficiency, and difficulty in large-scale continuous production.

[0006] The present invention proposes a fabric cutting and feeding device, comprising a first base, a second base, a roller, a conveyor belt, a drive component, and a limiting and cleaning assembly;

[0007] The roller and conveyor belt are installed between the first and second platforms. The rolled fabric is placed in the upper area between the roller and the conveyor belt. The back of the first and second platforms is equipped with a guide rail cutter for cutting the fabric. The conveyor belt is driven by a drive unit to unfold the rolled fabric to the position of the guide rail cutter for cutting.

[0008] The limiting and cleaning assembly is installed on the first and second bases and is used to press against the fabric being conveyed on the conveyor belt;

[0009] The limiting and cleaning assembly includes a loading seat, an elastic element, a hollow tube, and guide wheels. The two loading seats are each equipped with an elastic element. The hollow tube is rotatably connected between the two elastic elements and is arranged laterally above the conveyor belt. Two symmetrically arranged guide wheels are fixedly mounted on the hollow tube, and the two guide wheels abut against the two sides of the top surface of the conveyor belt, respectively.

[0010] As a further optimization of the present invention, a groove is provided on the inner side of the first base, and a first fixing plate and a second fixing plate are installed in sequence in the groove. A first motor is installed on the outer side of the first fixing plate. The shaft roller is arranged laterally between the first fixing plate and the second base. One end of the shaft roller is connected to the output end of the first motor, and the other end is rotatably engaged with the inner side of the second base. A conveying roller arranged parallel to the shaft roller is rotatably connected between the second fixing plate and the second base. A first shaft and a second shaft are rotatably connected between the first base and the second base. The first shaft is arranged parallel to the conveying roller, and the second shaft is located below the first shaft. The conveyor belt is fitted on the conveying roller, the first shaft, and the second shaft, and the conveying roller is driven by a driving component to drive the conveyor belt to rotate.

[0011] As a further optimization of the present invention, the elastic element includes a slider, a movable rod, and a spring. Two loading seats are respectively installed on a second base and a second fixed plate. Each of the two loading seats has a vertically arranged sliding opening. A slider is slidably fitted in each of the two sliding openings. A movable rod is fixed to the top of each of the two sliders. The top ends of the two movable rods slide through the top of the two loading seats respectively. A spring is sleeved on each of the two movable rods. The two ends of the two springs are respectively connected to the top walls of the two sliders and the two loading seats. The hollow tube is rotatably connected between the two sliders. Multiple dust blowing holes are arranged at intervals along the length of the hollow tube. An air supply component for supplying ion wind to the hollow tube is installed on one slider.

[0012] As a further optimization of the present invention, the air supply component includes a rotary joint, an air supply pipe and an ion fan. The rotary joint is installed on the side of a slider away from the hollow tube, and one end of the hollow tube rotates through a slider and connects to the rotating air outlet end of the rotary joint. The two ends of the air supply pipe are respectively connected to the air inlet end of the rotary joint and the air outlet end of the ion fan. The ion fan is installed on a second base.

[0013] As a further optimization of the present invention, the limiting cleaning component also includes a flexible brush component, and each of the two guide wheel disks has a cavity, and a flexible brush component sleeved on the hollow tube is installed in each of the two cavities.

[0014] As a further optimization of the present invention, the flexible brush component includes a brush part, a chuck, and a magnetic ring. Brush parts fitted onto a hollow tube are installed in the cavities of both guide rollers. A chuck, slidably fitted onto the hollow tube, is connected to one adjacent end of each of the two brush parts. The two chucks are respectively inserted into the cavities of the two guide rollers. A magnetic ring is fixed to one adjacent side of each of the two chucks. The brush part has a first state and a second state. In the first state, it is located within the cavity. In the second state, the chuck moves along the hollow tube, causing the brush part to unfold and contact the surface of the conveyor belt. The two magnetic rings are magnetically connected.

[0015] As a further optimization of the present invention, the brush part includes a flexible cover, the flexible cover is disposed in the cavity of the guide wheel disk, and the flexible cover is sleeved on the hollow tube. The two ends of the flexible cover are respectively connected to the inner wall of the guide wheel disk and the chuck, and the outer periphery of the flexible cover is connected with densely arranged bristles.

[0016] As a further optimization of the present invention, the driving component includes a second motor, a loading plate, a driving wheel, a driven wheel, and a transmission belt. The loading plate is mounted on a first base, and the second motor is mounted on the side of the loading plate. The output end of the second motor is connected to the driving wheel. The end of the conveying roller is connected to a rotating rod that rotates through a second fixed plate. The driven wheel is fixed at the end of the rotating rod away from the conveying roller and located below the driving wheel. A transmission belt is fitted between the driving wheel and the driven wheel.

[0017] As a further optimization of the present invention, a controller is installed on the first base, and the guide rail cutter, the first motor, and the second motor are all electrically connected to the controller.

[0018] The above-described technical solution of the present invention has the following beneficial technical effects:

[0019] In use, the roll of fabric is placed in the upper area between the roller and the conveyor belt. Then, the first motor drives the roller to rotate, and the drive unit drives the conveyor belt to rotate, causing the roll of fabric to roll and unfold to the position of the guide rail cutter. The guide rail cutter then cuts the fabric laterally. The above design, through the cooperation of the roller and the conveyor belt, realizes the automated unfolding and cutting of the fabric. It can effectively avoid the problems of fabric deviation or slippage that are easy to occur during manual fabric laying, ensuring the accuracy of fabric laying and thus ensuring the accuracy of cutting. At the same time, it reduces the manual intervention, improves the cutting efficiency, and is conducive to realizing large-scale, continuous production.

[0020] When the fabric is unrolled, it may shift. Therefore, a limiting and cleaning assembly is designed on the first and second bases to press and limit the fabric. When the roll of fabric is rolled and unrolled, an upward force can be applied to the hollow tube in the limiting and cleaning assembly, causing the elastic elements at both ends of the hollow tube to be elastically compressed upward. The two guide rollers fixed on the hollow tube move upward away from the conveyor belt, so that the fabric can be placed on the surface of the conveyor belt. Then the force applied to the hollow tube is removed. Under the elastic action of the elastic elements, the two guide rollers on the hollow tube can press against the fabric. When the conveyor belt is running, it can drive the guide rollers and the hollow tube to run together. The guide rollers can limit the unfolded fabric. The above can effectively press and constrain the position of the fabric during the conveying process, prevent it from shifting or sliding, and thus ensure the accuracy of laying and cutting.

[0021] When rolled fabric is unrolled, it may generate static electricity and attract dust from the air. When the conveyor belt rotates synchronously with the guide wheel and the hollow tube, ion air can be delivered to the hollow tube through the air supply device. Then it can be discharged through the dust blowing holes opened on the hollow tube and blown onto the fabric during the unrolling process. This can effectively remove dust and static electricity from the fabric, eliminate the potential interference of static electricity to subsequent processes, and the ion air blown onto the fabric can also increase the tightness between the fabric and the conveyor belt. Through the action of air pressure, it can also effectively suppress fabric wrinkles and improve the flatness of the fabric.

[0022] After the fabric is cut and the conveyor belt is not in use, dust easily accumulates on its surface. When the roll of fabric needs to be unrolled for cutting again, the dust will contaminate the fabric. Under these conditions, before use, the chucks inside the two guide wheels can be slid along the hollow tube, causing the chucks to unfold the brush section inside the guide wheels. The magnetic rings on adjacent sides of the two chucks are magnetically connected, and the bristles in the brush section contact the surface of the conveyor belt. Then, the drive unit can drive the conveyor belt to rotate the two guide wheels and the hollow tube. The unfolded brush section on the two guide wheels rotates synchronously, and the surface of the conveyor belt can be cleaned by the bristles on the brush section. During the cleaning process, a vacuum cleaner can be placed at the cleaning area to remove the dust. The above design can turn the guide wheels into a cleaning tool, realizing self-cleaning of the working surface of the conveyor belt and effectively avoiding the contamination of new fabric by dust accumulated when the belt is not in use.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0032] Example 1

[0033] like Figure 1-7 As shown, the fabric cutting and feeding device proposed in this invention includes a first base 1, a second base 2, a roller 3, a conveyor belt 4, a drive component 5, and a limiting and cleaning component 6.

[0034] The roller 3 and the conveyor belt 4 are installed between the first base 1 and the second base 2. The rolled fabric is placed in the upper area between the roller 3 and the conveyor belt 4. The back of the first base 1 and the second base 2 are equipped with a guide rail cutter 101 for cutting the fabric. The conveyor belt 4 is driven by the drive unit 5 to make the rolled fabric unfold to the position of the guide rail cutter 101 for cutting.

[0035] The limiting and cleaning component 6 is installed on the first base 1 and the second base 2 and is used to press against the fabric conveyed on the conveyor belt 4;

[0036] The limiting and cleaning assembly 6 includes a loading seat 61, an elastic element 62, a hollow tube 63, and a guide wheel 64. The two loading seats 61 are each equipped with an elastic element 62. The hollow tube 63 is rotatably connected between the two elastic elements 62 and is arranged laterally above the conveyor belt 4. Two symmetrically arranged guide wheels 64 are fixedly mounted on the hollow tube 63. The two guide wheels 64 respectively abut against the two sides of the top surface of the conveyor belt 4.

[0037] In use, the rolled fabric is placed in the area above the roller 3 and the conveyor belt 4. The drive unit 5 drives the conveyor belt 4 to rotate, thereby realizing the automated unfolding of the fabric and avoiding the tedious operation of manual fabric laying. The unfolded fabric is conveyed to the guide rail cutter 101. The guide rail cutter 101 can move along the preset guide rail to complete the transverse cutting operation of the fabric. At the same time, the limiting and cleaning components 6 installed on the first base 1 and the second base 2 press against the fabric on the conveyor belt 4, which can effectively constrain the position of the fabric during the conveying process and prevent the fabric from shifting or sliding. The above realizes the automated process of fabric from placement to unfolding to cutting, which not only solves the problem of low accuracy of manual fabric laying, but also reduces the links of manual intervention, improves cutting efficiency, and facilitates large-scale and continuous production.

[0038] In this embodiment, a groove is provided on the inner side of the first base 1, and a first fixing plate 102 and a second fixing plate 103 are installed in the groove in sequence. A first motor 31 is installed on the outer side of the first fixing plate 102. A shaft roller 3 is arranged laterally between the first fixing plate 102 and the second base 2. One end of the shaft roller 3 is connected to the output end of the first motor 31, and the other end is rotatably engaged with the inner side of the second base 2. A conveying roller 41 arranged parallel to the shaft roller 3 is rotatably connected between the second fixing plate 103 and the second base 2. A first shaft 42 and a second shaft 43 are rotatably connected between the first base 1 and the second base 2. The first shaft 42 is arranged parallel to the conveying roller 41, and the second shaft 43 is located below the first shaft 42. A conveyor belt 4 is fitted on the conveying roller 41, the first shaft 42 and the second shaft 43, and the conveying roller 41 is driven by the driving component 5 to drive the conveyor belt 4 to rotate.

[0039] It should be noted that the conveyor roller 41, the first shaft 42 and the second shaft 43 form a conveying surface that supports the operation of the conveyor belt 4. In use, the drive unit 5 drives the conveyor roller 41 to rotate. The conveyor roller 41 drives the conveyor belt 4 to circulate around the conveyor roller 41, the first shaft 42 and the second shaft 43 through the friction between the conveyor roller 41 and the conveyor belt 4, so as to realize the continuous conveying of the fabric.

[0040] In this embodiment, the elastic element 62 includes a slider 621, a movable rod 622, and a spring 623. Two loading seats 61 are respectively installed on the second base 2 and the second fixed plate 103. Each of the two loading seats 61 has a vertically arranged sliding opening. The slider 621 is slidably fitted in each of the two sliding openings. The top of each slider 621 is fixed with a movable rod 622. The top ends of the two movable rods 622 slide through the top of the two loading seats 61 respectively. Each movable rod 622 is fitted with a spring 623. The two ends of the two springs 623 are respectively connected to the top walls of the two sliders 621 and the two loading seats 61. The hollow tube 63 is rotatably connected between the two sliders 621. The hollow tube 63 has a plurality of spaced dust blowing holes 631 along its length. One slider 621 is equipped with an air supply element 66 for supplying ion wind to the hollow tube 63.

[0041] When the operator applies an upward force to the hollow tube 63, the slider 621 slides upward along the sliding opening and compresses the spring 623, causing the hollow tube 63 to move upward to facilitate the placement of the fabric. After the force is removed, the elastic restoring force of the spring 623 will push the slider 621 downward, causing the hollow tube 63 and the guide wheel 64 to press against the fabric, achieving adaptive elastic limiting. When the conveyor belt 4 runs and unfolds the fabric, it can synchronously drive the guide wheel 64 and the hollow tube 63 to rotate. Under the action of the guide wheel 64, the fabric can be limited.

[0042] It should be noted that the guide wheel 64 presses against the conveyor belt 4 and is located above the conveyor roller 41. In fact, it is in hard contact with the conveyor roller 41. The rotation of the conveyor roller 41 drives the conveyor belt 4 to run, and transmits the force to the guide wheel 64.

[0043] During the fabric conveying process, ion air can be delivered to the hollow tube 63 through the air supply component 66. Then, the ion air is blown onto the fabric through the dust blowing hole 631 on the hollow tube 63. The ion air can effectively neutralize the static electricity generated by friction during the unfolding process of the fabric. The elimination of static electricity can prevent the fabric from adsorbing dust in the air. At the same time, the ion air itself has a certain wind force, which can directly blow away the dust attached to the surface of the fabric to achieve the dust removal effect. In addition, the ion air blown onto the fabric can also increase the air pressure between the fabric and the conveyor belt 4, making the fabric fit the conveyor belt 4 more closely, effectively suppressing fabric wrinkles, improving the flatness of the fabric surface, and making subsequent cutting smoother.

[0044] In this embodiment, the air supply component 66 includes a rotary joint 661, an air supply pipe 662, and an ion fan 663. The rotary joint 661 is installed on the side of a slider 621 away from the hollow tube 63, and one end of the hollow tube 63 rotates through the slider 621 and connects to the rotating air outlet end of the rotary joint 661. The two ends of the air supply pipe 662 are respectively connected to the air inlet end of the rotary joint 661 and the air outlet end of the ion fan 663. The ion fan 663 is installed on the second base 2. In use, the ion fan 663 delivers ionized air through the air supply pipe 662 to the rotary joint 661, and then through the rotary joint 661 into the hollow tube 63, and finally discharges it through the dust blowing hole 631 opened on the hollow tube 63.

[0045] Example 2

[0046] After the fabric is cut and the conveyor belt 4 is no longer in use, dust easily adheres to its surface. When the roll of fabric needs to be unrolled and cut again, the dust will contaminate the fabric. Therefore, based on Embodiment 1, a flexible brush 65 is provided inside the guide wheel 64, as follows:

[0047] In this embodiment, the limiting cleaning component 6 also includes a flexible brush 65. Both guide wheel disks 64 have cavities, and each cavity is fitted with a flexible brush 65 that is sleeved on the hollow tube 63. The flexible brush 65 is normally stored in the cavity of the guide wheel disk 64 and does not affect the normal guiding function of the guide wheel disk 64. When it is necessary to clean the surface of the conveyor belt 4, the brush part 651 can be unfolded so that its bristles 6512 contact the conveyor belt 4, and automatic cleaning is achieved during the operation of the conveyor belt 4 to keep the working surface clean and avoid dust accumulation during the shutdown period from contaminating the new fabric.

[0048] In this embodiment, the flexible brush component 65 includes a brush part 651, a chuck 652, and a magnetic ring 653. The brush part 651, which is sleeved on the hollow tube 63, is installed in the cavity of each of the two guide wheel disks 64. The adjacent ends of the two brush parts 651 are connected to a chuck 652 that is slidably sleeved on the hollow tube 63. The two chucks 652 are respectively inserted into the cavity of the two guide wheel disks 64. The adjacent sides of the two chucks 652 are fixed with magnetic rings 653. The brush part 651 has a first state and a second state. In the first state, it is located in the cavity. In the second state, the chuck 652 moves along the hollow tube 63 to drive the brush part 651 to unfold and contact the surface of the conveyor belt 4. The two magnetic rings 653 are magnetically connected.

[0049] The brush part 651 can be extended from the guide wheel disk 64 by sliding the chuck 652. The two chucks 652 are attracted and fixed to each other by the magnetic ring 653, ensuring that the brush part 651 remains stable in the unfolded state. This structure realizes the multi-purpose function of the guide wheel disk 64, which can guide the fabric and can also be converted into a cleaning tool, thus improving the functional versatility of the device.

[0050] In this embodiment, the brush part 651 includes a flexible cover 6511. The flexible cover 6511 is disposed in the cavity of the guide wheel disk 64 and is sleeved on the hollow tube 63. The two ends of the flexible cover 6511 are respectively connected to the inner wall of the guide wheel disk 64 and the chuck 652. The outer periphery of the flexible cover 6511 is connected with densely arranged bristles 6512.

[0051] The flexible cover 6511 is normally stored in the cavity of the guide wheel disk 64. When in use, the sliding chuck 652 can extend the flexible cover 6511 from the guide wheel disk 64. After the bristles 6512 on the flexible cover 6511 are unrestrained, they unfold and contact the surface of the conveyor belt 4. When the driving component 5 drives the conveyor roller 41 to drive the conveyor belt 4 to rotate, the conveyor belt 4 can drive the guide wheel disk 64 and the hollow tube 63 to rotate synchronously. The flexible cover 6511 on the guide wheel disk 64 also rotates synchronously. The bristles 6512 on the flexible cover 6511 can effectively brush away the dust on the conveyor belt 4.

[0052] It should be noted that when brushing the dust off the conveyor belt 4 with the brush 6512, a vacuum cleaner needs to be placed in the cleaning area to remove the dust in real time.

[0053] It should be further explained that, in order to further improve the cleaning effect, in actual use, openings can be made on the outer periphery of the flexible cover 6511, and the air supply component 66 can deliver ion air into the hollow tube 63 and discharge it through the dust blowing hole 631 on it, and finally discharge it through the openings on the flexible cover 6511, so as to improve the dust cleaning effect.

[0054] In this embodiment, the driving component 5 includes a second motor 51, a loading plate 52, a driving wheel 53, a driven wheel 54, and a transmission belt 55. The loading plate 52 is mounted on the first base 1. The second motor 51 is mounted on the side of the loading plate 52, and the output end of the second motor 51 is connected to the driving wheel 53. The end of the conveying roller 41 is connected to a rotating rod 411 that rotates through the second fixed plate 103. The driven wheel 54 is fixed at the end of the rotating rod 411 away from the conveying roller 41 and located below the driving wheel 53. The driving wheel 53 and the driven wheel 54 are fitted together by the transmission belt 55. In use, the second motor 51 drives the driving wheel 53 to rotate, and the transmission belt 55 mounted on it drives the driven wheel 54 to rotate. The driven wheel 54 drives the conveying roller 41 to rotate through the rotating rod 411, thereby driving the conveyor belt 4 to run.

[0055] In this embodiment, a controller 21 is installed on the first base 1, and the guide rail cutter 101, the first motor 31, and the second motor 51 are all electrically connected to the controller 21.

[0056] Operators can preset parameters such as fabric cutting length and conveying speed through controller 21. Controller 21 will automatically control the start, running speed and stop of the second motor 51 according to the preset parameters, thereby adjusting the conveying speed and conveying distance of conveyor belt 4 to ensure that the fabric can be accurately conveyed to the cutting position. When the fabric reaches the preset cutting position, controller 21 will send a command to control the guide rail cutter 101 to start and complete the cutting operation. At the same time, controller 21 can coordinate the running speed of the first motor 31 and the second motor 51 to match the rotation speed of the shaft roller 3 with the running speed of the conveyor belt 4 to ensure the smooth unfolding of the fabric.

[0057] The embodiments of the present invention have been described above, but the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
