DETAILED DESCRIPTION

[0041] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] Please see the attached Figure 1-4 The rotary square towel machine described in the present invention includes a frame 1, a processing table 2, a duplicating machine 3, a smoothing component 4, a label feeding mechanism 5, a cloth rotating mechanism 6, a material receiving component 7 and a transmission component 8; the frame 1 is provided with a bearing space; the processing table 2 is arranged inside the bearing space; the duplicating machine 3 is arranged on one side of the processing table 2, and the front end of the duplicating machine 3 is provided with a smoothing component 4, which is used to smooth the cloth and position the cloth so that its position does not deviate during processing, thereby facilitating subsequent duplicating processing, wherein the duplicating machine can be moved horizontally through the slide rail assembly, thereby facilitating the adjustment of the position of the duplicating machine.

[0043] The label feeding mechanism 5 is located at the front end of the overlock machine 3, and is used to feed the label into the overlock machine 3. The label can be sewn on the fabric as the fabric passes through the overlock machine; the cloth rotating mechanism 6 is located above the processing table 2, and is used to perform multilateral rotation of the fabric on the processing table 2. The rotation here is to rotate the three sides of the fabric in sequence, and the angle of each rotation is 90° counterclockwise; the material receiving component 7 is located on one side of the processing table 2, and is used to collect finished products; in addition, it also includes a transmission component 8, which is provided above the processing table 2, and is used to cooperate with the overlock processing of the overlock machine 3, the cloth rotating operation of the cloth rotating mechanism 6, and to transfer the fabric on the processing table 2 forward to the material receiving component 7.

[0044] For details, please refer to the attached Figure 5 The smoothing assembly 4 includes a lower pressing bracket 40, and a lower pressing surface 41 is provided at the front end of the lower pressing bracket 40; an upper pressing plate 43 is provided above the lower pressing bracket 40, which can be lifted up and down by a cloth pressing cylinder 42, and the front end of the upper pressing plate 43 has an upper pressing surface 45, and the upper pressing surface 43 and the lower pressing surface 41 are arranged relative to each other in an eight-shaped shape, and the outer opening in the eight-shaped shape is larger than the inner opening; three guide columns 44 are provided between the upper pressing surface 45 and the lower pressing surface 41, which play a guiding role when the upper pressing surface and the lower pressing surface are close to each other.

[0045] In addition, a buffer 46 is provided on the upper pressing plate 43, and the bottom of the buffer is arranged between the upper pressing plate and the lower pressing plate after passing through the upper pressing plate, and the straight-line distance between the buffer and the lower pressing plate is smaller than the straight-line distance between the upper pressing surface and the lower pressing surface; in this way, when the cloth enters the smoothing component 4, the piston rod of the cloth pressing cylinder 42 retracts, driving the upper pressing surface 43 and the lower pressing surface 41 connected to the cloth pressing cylinder 42 to approach each other, thereby smoothing the cloth before entering the overlocking machine, and because the straight-line distance between the buffer and the lower pressing plate is smaller than the distance between the upper pressing surface and the lower pressing surface, when the upper pressing surface 43 and the lower pressing surface 41 approach to smooth the cloth, the buffer presses the cloth tightly, and then the cloth is dragged over by the presser foot on the subsequent overlocking machine, thereby avoiding the cloth from being tilted when transported to the overlocking machine, ensuring that the position of the cloth will not deviate during transmission.

[0046] Please see the attached Figure 6The label feeding mechanism 5 includes a label dispensing machine 50 and a label feeding component 51 located at the front end of the label dispensing machine 50. The label feeding component 61 feeds the label onto the fabric and sews the label onto the fabric through a subsequent overlocking machine; wherein, the label feeding component 51 includes a forward cylinder 510, and a driving motor 511 is provided at the front end of the forward cylinder 510; the rotating shaft of the driving motor 511 is connected to a gear (not shown in the figure); the gear is connected to a rack 512, and a lower clamping plate 513 is provided at one end of the rack 512, and an upper clamping plate 515 that can move up and down by a clamping cylinder 514 is provided at the upper end of the lower clamping plate 513, and the upper clamping plate 515 and the lower clamping plate 513 are L-shaped.

[0047] During actual operation, the driving motor 511 drives the rack 512 to move forward through the gear, so that the label cut by the labeling machine 50 is located between the upper clamping plate 515 and the lower clamping plate 513, and the clamping cylinder 514 drives the upper clamping plate 515 to move downward to clamp the label, and then the forward cylinder 510 drives the label to move an end distance upward so that the label is just above the fabric, and the upper clamping plate 515 and the lower clamping plate 513 are released, and the label falls on the fabric, and then the label and the fabric are synchronously smoothed by the smoothing component 4 for subsequent overlocking processing.

[0048] In addition, two infrared sensors 516 are provided on the rack 512 , and the two infrared sensors are used to sense the length of the delivered label to facilitate subsequent cutting.

[0049] Please see the attached Figure 7 The cloth rotating mechanism 6 includes a rotating support 60, a rotating motor 61, a first connecting bar 62, a first connecting bar 63 and a pressing component; an installation space is provided on the rotating bracket 60; the rotating motor 61 is provided on the rotating bracket 60, and the rotating shaft of the rotating motor 61 is provided in the installation space; one end of the first connecting bar 62 is connected to the rotating shaft located in the installation space; the second connecting bar 63 is connected to the first connecting bar 62; the two pressing components are provided at the lower end of the first connecting bar 62, and one pressing component is provided at the lower end of the second connecting bar 63.

[0050] The pressing assembly includes a pressing cylinder 64 , which drives a pressing bracket 66 on a slide rail 65 to move up and down; a pressing block 67 is provided on the pressing bracket 66 .

[0051] In actual operation, when one side of the fabric is overlocked, the rotary motor 61 is used to move the pressing assembly to the top of the edge of the fabric, and then the pressing cylinder 64 drives the pressing block 67 on the slide rail to press the fabric tightly. The rotary motor 61 then rotates the fabric 90 degrees, so that the other side of the fabric is also set on the side of the overlocking machine for overlocking. Repeating this operation three times in sequence can complete the overlocking of the four sides of the fabric.

[0052] Among them, the number and setting positions of the pressing components can be adjusted according to long-term needs. The two pressing components are set at the lower end of the first connecting bar 62 to ensure that the cloth can be rotated more stably; and the pressing component located at the lower end of the second connecting bar 63 is used to press down cloth that is wider than the pressing component at the lower end of the first connecting bar 62. In this way, one device can meet the needs of products of different sizes.

[0053] As a further preferred embodiment, please refer to the attached Figure 2 and 8 The material receiving assembly 7 includes a sliding plate 70 located on one side of the processing table 2; the sliding plate 70 is movably arranged on the frame 1 through a rodless cylinder 711 and a sliding guide rail 71; a material receiving plate 72 is provided below the sliding plate 70; a transmission assembly is provided above the sliding plate 70; a grabbing mechanism for grabbing the cloth is also provided above the sliding 70; the grabbing mechanism includes a grabbing bracket 73, and a grabbing cylinder 74 is provided on the grabbing bracket 73; the piston rod of the grabbing cylinder 74 is downwardly arranged on a carrier 75; the carrier 75 is provided with a moving rod 77 which can move up and down in a sliding seat 76; four grabbing assemblies are provided at the bottom of the carrier 75, distributed around the cloth; the grabbing assembly includes a power cylinder 78, and two clamping jaws 79 driven to release / clamp by the power cylinder 78.

[0054] During operation, after the finished product is transmitted from the transmission component 8, the grabbing cylinder 74 drives the entire carrier 75 to move downward under the guidance of the moving rod 77, and the power cylinder 78 drives the two clamps 79 to clamp the finished product. Then the transmission component releases the finished product, and then the sliding plate 70 moves to the right on the sliding rail 71 through the push of the rodless cylinder 711, exposing the receiving plate located under the sliding plate, and then the two clamps are released, so that the finished product falls directly onto the receiving plate 72, and the above operation is repeated until the receiving plate is full of finished products.

[0055] In addition, please see the attached Figure 9The transmission assembly 8 includes a transmission cylinder 80 provided on the frame 1; a pressing frame 81 is provided at the lower end of the transmission cylinder 80; two synchronous wheel assemblies 82 are provided at the lower end of the pressing frame 81, and the synchronous wheel assembly includes two synchronous wheels connected by a synchronous belt; the two synchronous wheel assemblies are connected by a power shaft 83, and the power shaft 83 is driven by a power motor 84 through a power transmission assembly 85, and the power transmission assembly here is a synchronous belt transmission assembly; when it is necessary to press the cloth and transmit it, the transmission cylinder starts to work, and the transmission cylinder drives the entire pressing frame to move downward, so that the left and right synchronous belts press the cloth, and then the power motor 84 brings power to the two synchronous belts through the transmission shaft, driving the cloth forward for transmission; wherein, when the width of the cloth is short, only one synchronous wheel assembly is needed to cooperate with two pressing assemblies located at the lower end of the first connecting strip for production and processing; when the width of the cloth is long, two synchronous wheel assemblies are needed to cooperate with a pressing assembly located at the lower end of the second connecting strip for production and processing.

[0056] The working process of this rotary square towel machine is as follows: first, the cloth is placed on the processing table, and then the transmission component sends the cloth to the smoothing component for smoothing, and then the overlocking machine overlocks the first side of the cloth. After the overlocking of the first side is completed, the cloth is rotated through the cloth rotating mechanism to rotate the second and third sides of the cloth to the overlocking machine in turn for overlocking the second and third sides respectively, and then when the cloth rotating mechanism rotates the fourth side of the cloth to the overlocking machine, the label feeding mechanism sends the label to the fourth side of the cloth, and then the overlocking machine overlocks the label and the fourth side together, and finally the transmission mechanism sends the finished product to the receiving component for collection of the finished product.

[0057] The rotating handkerchief of the present invention has a compact overall structure and can automatically realize the rotation of three sides of the cloth, thereby automatically completing the four-side overlock processing of the cloth, and finally automatically completing the collection of the finished products. The entire process is fully automated, which reduces manpower, improves production efficiency, reduces labor costs, and meets the production and processing needs of enterprises.
