DETAILED DESCRIPTION

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not constitute a limitation of the present invention.

[0038] Please see attached Figure 1-10 A blanket hemming machine described in one embodiment of the present invention comprises a feeding part 1, a turning part 2 and an hemming part 3 placed in sequence; the blanket hemming machine is applicable to large-sized blankets. When working, the large-sized blanket is fixed in length by the feeding part 1, and then sent to any one of the hemming devices 30 in the hemming part 3 through the turning part 2 for hemming processing on the four sides of the blanket. Moreover, multiple blankets can be hemmed at the same time, with high processing efficiency, and blankets can be processed in batches.

[0039] Specifically, the feeding part 1 includes a feeding mechanism 10 and a cloth cutting mechanism 10 located at the front end of the feeding mechanism 11; during actual work, the blanket is first placed on the feeding part 1, and the feeding part 1 drives the blanket to be transmitted forward. When the length of the blanket is determined, the cloth cutting mechanism 10 cuts the blanket, and then the steering part 2 sends the blanket to the hemming device 30 in the corresponding hemming part.

[0040] The steering part 2 includes an L-shaped steering bracket 20, on which a feeding rack 21 which can rotate around the upper end of the steering bracket 20 is provided, and a plurality of transmission rollers 22 are provided on the feeding rack 21, wherein one of the transmission rollers 22 is driven to rotate by a corresponding motor, so that the blanket can be transmitted forward; a movably connected telescopic member 23 is provided at the bottom of the feeding rack 21, and in this embodiment, the telescopic member 23 is a cylinder, and the other end of the telescopic member 23 is provided at the bottom of the rotating bracket 20, so that when the telescopic member 23 is extended and retracted, it can drive the feeding rack 21 to rotate horizontally on the steering bracket 20, so that the blanket is transmitted to the feeding table 32 in any one of the hemming devices for hemming processing.

[0041] In the embodiment, the hemming portion 3 is composed of four hemming devices 30 arranged in parallel up and down. In practice, the hemming device 30 includes a workbench 31, a rotating shaft (not shown in the figure), a rotating frame 33, an extension strip 34, a connecting strip 35, a pressing assembly 36, a sewing machine 37, an hemming strip feeder 38 and a pressing assembly 39; the workbench 31 is provided with a traversable feeding table 32, and the feeding table 32 is driven by two oppositely arranged rollers to drive the blanket to be linearly transmitted on the feeding table 32; the rotating shaft is arranged above the feeding table 32, and the rotating shaft is driven to rotate on the feeding table 32 by the corresponding rotating shaft motor.

[0042] The rotating frame 33 is driven by the rotating shaft to rotate synchronously on the feeding table 32 ; three extension bars 34 extend outward from the rotating frame 33 , and the front ends of the three extension bars 34 are fixedly connected to each other by two connecting bars 35 .

[0043] Among them, two pressing assemblies 36 are provided on the first extension bar 34, and one pressing assembly 36 is provided on the second extension bar and the third extension bar, and the pressing assembly includes a pressing cylinder 360, a clamping bar 361, a clamping rod 362 and a clamping plate 363; multiple pressing cylinders 360 are installed on the extension bar 34, and the clamping bar 361 can be moved up and down by the pressure wheel cylinder 360, and the clamping rod 362 is vertically arranged on the clamping bar 361, and after the clamping rod 362 passes through the clamping bar 361, a buffer spring 364 is sleeved under the clamping bar 361; the clamping plate 363 is arranged at the bottom of the clamping rod 362 and is connected to the buffer spring 364, so that the pressing cylinder 360 drives the clamping plate 363 to move downward to press the blanket, and at the same time utilizes the buffering elasticity of the buffer spring 364 to avoid the clamping plate 363 being pressed too tightly to damage the blanket.

[0044] A pressing assembly 36 is also provided on the connecting strip between the second extension strip and the third extension strip. Three vertically arranged pressing plates 363 are provided on the pressing assembly 36 of the connecting strip. A clamping rod 362 is correspondingly provided on each pressing plate 363. The three clamping rods 362 are arranged on the clamping strip, and a buffer spring 364 is provided on the clamping rod 362.

[0045] In addition, the sewing machine 37 is arranged on one side of the workbench 31, and the sewing part of the sewing machine 37 is arranged at the edge of the feeding table 32, which is used to sew the edging strip to the edge of the blanket; the edging strip feeder 38 is arranged on one side of the workbench 31, which is used to feed the edging strip to the edge of the blanket.

[0046] At the same time, a pressing assembly 39 is also provided at the edge of the feeding table 32, which is used to press the sewn edge of the blanket when the sewing part sews the hemming strip to the edge of the blanket; specifically, the pressing assembly 39 includes a pressing cylinder 390, the piston rod of which is movably connected to a pressing block 392, a pressing roller 391 is provided at the front end of the pressing block 392, and one end of the pressing block 392 is rotatably arranged above the workbench 31; in this way, when the sewing machine 37 sews the edge of the blanket, the pressing cylinder 390 drives the pressing roller 391 to rotate, thereby pressing the edge of the blanket, which is convenient for the sewing machine to sew the hemming of the blanket.

[0047] In addition, since the blanket hemming machine is a device for large blankets, a staircase 4 for people to walk on is also provided on one side of the hemming part 3, so that the staff can go up and check the status of the equipment in real time to ensure the normal operation of the equipment.

[0048] The working process is as follows:

[0049] First, the blanket is placed on the feeding part, which fixes the length of the blanket and sends it to the steering part. Then the telescopic part drives the steering part to adjust the position of the blanket and send it to the feeding table of the corresponding hemming device.

[0050] When the blanket is located in the hemming device, the feeding table conveys the blanket forward, and at the same time, the sewing machine cooperates with the hemming assembly and the hemming strip feeder to perform hemming processing on one side of the blanket.

[0051] When the hemming process on one side of the blanket is completed, the edge pressing assembly 39 releases one side of the blanket, and the pressing assembly 36 on the extension strip and the connecting strip moves downward, so that the blanket as a whole is pressed against the feed table 32 by the pressing plate, and then the rotating shaft drives the entire blanket to rotate 90° counterclockwise on the feed table 32, so that the other side of the blanket is rotated to the edge pressing assembly 39, and the pressing assembly 36 moves upward to release the blanket, and the edge pressing assembly 39 presses the other side of the blanket, and then the sewing machine cooperates with the hemming strip feeder to perform hemming process on the other side of the blanket, and the above operations are repeated in sequence, so as to automatically complete the hemming and sewing process on the four sides of the blanket.

[0052] The blanket hemming machine of the present invention has a compact overall structure and a reasonable layout. It can automatically send the blanket to a plurality of parallel arranged hemming devices after the blanket is fixed in length, and can realize automatic four-side hemming strip processing for a plurality of blankets at one time. It has high processing efficiency and is in line with the batch production and processing of enterprises. It is suitable for the processing of large-size blankets and has high practicality and promotion value.

[0053] The above are only specific application examples of the present invention and do not constitute any limitation on the protection scope of the present invention. Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the protection scope of the present invention.
