[0027] See also Figure 1-5 The utility model describes the above technical solution in detail through the following embodiments:

[0028] like Figure 1-Figure 5As shown, a textile fabric edge trimming device includes a pressing plate 1 and a bottom plate 2. The pressing plate 1 and the bottom plate 2 are hinged to each other at their head ends. Through the hinged relationship, the pressing plate 1 and the bottom plate 2 can clamp the fabric body 10 when they are folded, which is convenient for placing the fabric body 10 and taking out the fabric body 10 after the edge trimming is completed. The bottom of the bottom plate 2 is provided with a sliding plate 7 that can slide on the sliding panel of the sewing machine. The sliding plate 7 slides on the sliding groove or the sliding plate provided on the sewing machine, so that the fabric can be trimmed along the motion trajectory, and the sliding plate The function is consistent with the principle of the sliding device installed in the existing sewing machine. The center of the pressing plate 1 and the bottom plate 2 are both provided with a sewing groove 8 for the sewing head of the sewing machine to pierce and trim the edges. The head end of the sewing groove 8 on the pressing plate 1 is provided with a card slot 6. The top of the card slot 6 is provided with a first groove 63. The bottom of the card slot 6 is provided with a second groove 64. The card slot 6 is provided with a clamping mechanism 60 that can clamp and position the folded fabric body 10. The clamping mechanism 60 includes an upper clamping component 61 and a lower clamping component 62. The upper clamping component 61 is located at the bottom of the card slot 6. The lower clamping assembly 62 is located in the first groove 63, and the lower clamping assembly 62 is located in the second groove 64. The tail end of the sewing groove 8 on the pressing plate 1 is provided with a push rod 32 that can push the fabric body 10 to move between the upper clamping assembly 61 and the lower clamping assembly 62. When the fabric body 10 is pushed by the push rod 32 to move between the upper clamping assembly 61 and the lower clamping assembly 62, the fabric body 10 is stably clamped by the anti-slip tooth plates provided on the upper clamping assembly 61 and the lower clamping assembly 62. After clamping, the manual operation is responsible for pushing the equipment to move and sew the fabric. The rear end of the pressing plate 1 is provided with a driving assembly 4 which is rotatably connected to the pressing plate 1, and the top of the pressing plate 1 is provided with a positioning assembly 5 for clamping the head end of the fabric body 10.

[0029] like Figure 4As shown, the upper clamping assembly 61 includes a first limiting rod 610, a connecting plate 611 and an upper pressure block 612. The first limiting rod 610 is provided with two, and the inner top wall of the first groove 63 is provided with two first limiting holes for slidingly limiting the first limiting rod 610. The top ends of the two first limiting rods 610 are connected to the connecting plate 611 together, and a handle is provided on the top of the connecting plate 611. Through the setting of the handle, when the clamping needs to be released, the clamping of the fabric body 10 can be temporarily released by manually pulling the handle, which is conducive to adjusting the clamping state during the clamping process, and can also solve the problem of wrinkles that are inconvenient to adjust during the clamping process. The bottom ends of the two first limiting rods 610 are connected to the upper pressure block 612 together, and the upper pressure block 612 is connected to the first groove. A first spring 613 is commonly connected between the inner top walls 63, and the lower clamping assembly 62 includes a second limiting rod 620, a bottom block 621 and a lower pressure block 622. When the bottom block 621 is in contact with the top of the bottom plate 2, the clamping force on the folded part of the fabric body 10 is increased to avoid the problem of falling off during the clamping process. Two second limiting rods 620 are provided, and the inner bottom wall of the second groove 64 is provided with two second limiting holes for slidingly limiting the second limiting rod 620. A second spring 623 is provided between the lower pressure block 622 and the inner bottom wall of the second groove 64. The top ends of the two second limiting rods 620 are commonly connected to the lower pressure block 622, and the bottom ends of the two second limiting rods 620 are commonly connected to the bottom block 621, and the bottom of the bottom block 621 is in contact with the bottom plate 2.

[0030] like Figure 4 As shown, the side close to the upper pressing block 612 and the lower pressing block 622 is provided with an anti-slip tooth plate for clamping the fabric body 10, and the two anti-slip tooth plates are meshed with each other to improve the firmness of clamping the fabric body 10 in the folded state and reduce the possibility of the fabric body 10 slipping during the fixing process.

[0031] like Figure 3 and Figure 5 As shown, the driving assembly 4 includes a rotating shaft 41, a crank 42 and a double-grooved wheel 43. The rotating shaft 41 is connected to the crank 42. The double-grooved wheel 43 is sleeved on the outer wall of the rotating shaft 41. The head end of the rotating shaft 41 is rotatably connected to the tail end of the pressure plate 1. The double-grooved wheel 43 is transmission-connected to two single-grooved wheels 33 through a belt. When the crank 42 is manually rotated, the double-grooved wheel 43 can be driven to rotate at the same time, and the transmission connection relationship can be used to synchronously drive multiple threaded sleeves 3 to rotate, so that the threaded sleeves 3 push the push rod 32 to push the fabric body 10. The fabric body 10 is pushed at a relatively slow speed. The fabric body 10 can be straightened during the pushing process, thereby reducing the problem of wrinkles in the fabric body 10 during the folding process of the fabric body 10.

[0032] like Figure 1 and Figure 3As shown, the positioning assembly 5 includes a fixed seat 51 and a lower pressure rod 52, the bottom of the fixed seat 51 is connected to the top of the pressure plate 1, the fixed seat 51 is hinged to the lower pressure rod 52, the head end of the lower pressure rod 52 is provided with a fixed cross plate 53, the tail end of the lower pressure rod 52 is provided with a pressure rod, and a return spring 54 is connected between the lower pressure rod 52 and the top of the pressure plate 1. The elastic force of the return spring 54 pushes the left end of the lower pressure rod 52 and the fixed cross plate 53 to move to the bottom and realize the extrusion and positioning of the fabric, so that when the fabric body 10 is pushed to unfold and move later, there is no need to manually position the corners of the fabric body 10, which ensures the stability of the positioning process and reduces the difficulty of positioning the fabric body 10.

[0033] like Figure 3 As shown, an opening and closing seam is provided between the pressing plate 1 and the bottom plate 2, and a pressure strip plate 9 is provided in the opening and closing seam. The pressure strip plate 9 is connected to the bottom of the pressing plate 1. The fabric body 10 can be clamped by the pressure strip plate 9 so that the fabric body 10 will not be offset during the edge trimming operation.

[0034] like Figure 1 As shown, a grip 11 is provided on the top of the pressing plate 1 for pushing the pressing plate 1 and the bottom plate 2 to slide, so that personnel can conveniently and manually push the pressing plate 1 and the bottom plate 2 to drive the fabric body 10 to move and trim.

[0035] Working principle: first, place the fabric in the opening and closing seam between the pressing plate 1 and the bottom plate 2, and place one side of the fabric on the top of the pressing plate 1. The elastic force of the return spring 54 pushes the left end of the lower pressing rod 52 and the fixed cross plate 53 to move to the bottom and squeeze the fabric into position. At this time, manually rotate the crank 42, and the rotation of the crank 42 drives the rotating shaft 41 and the double-grooved wheel 43 to rotate, and the transmission connection of the belt drives the two single-grooved wheels 33 to rotate. The rotation of the two single-grooved wheels 33 drives the threaded sleeve 3 connected thereto to rotate at the same time. The rotation of the threaded sleeve 3 cooperates with the interaction between the threads, and at the same time drives the two threaded telescopic rods 31 to perform telescopic movement in the threaded sleeve 3. The telescopic movement of the two threaded telescopic rods 31 drives the push rod 32 to move synchronously. At this time, the fabric body 10 is pushed to move toward the inside of the slot 6 by the push rod 32. Since the cross-section of the push rod 32 is a circle shaped setting, with the inclined setting of the side walls of the upper pressing block 612 and the lower pressing block 622, the push rod 32 pushes the fabric body 10 into between the upper pressing block 612 and the lower pressing block 622. At this time, the anti-slip tooth plates fixedly connected on the upper pressing block 612 and the lower pressing block 622 are pushed by the elastic force of the first spring 613 and the second spring 623, so that the fabric body 10 is clamped at the same time, and the crank 42 is rotated again, and the threaded sleeve 3 is driven to rotate by the crank 42, and the interaction between the threads drives the push rod 32 to reset, and then the pressing plate 1 is manually flipped over to fit with the bottom plate 2. At this time, the bottom of the pressure strip plate 9 positions the fabric, and at the same time the back of the bottom block 621 is squeezed, pushing the lower pressing block 622 to move toward the top, making the squeezing of the fabric more firm, starting the sewing machine, and manually pushing the grip rod 11 to make the sliding plate 7 slide in the sliding groove, and the thread needle of the sewing machine head passes through the two sewing grooves 8 to sew the edge of the fabric body 10.
