Description

Technical Field

[0001] The utility model relates to the technical field of embroidery machines, in particular to a cloth pressing device of an embroidery machine. Background Art

[0002] Computerized embroidery machines are the most advanced embroidery machines of our time. They enable traditional hand embroidery to be achieved at high speed and high efficiency, and can also achieve the requirements of multi-level, multi-function, uniformity and perfection that hand embroidery cannot achieve.

[0003] Chinese utility model patent application number 202222239811.X discloses a fabric pressing and fixing device for an embroidery machine. The above technical solution transmits the fabric by unwinding and rewinding, threading the fabric at the embroidery mouth, and rotating and pulling the fabric on both sides of the embroidery table by rubber pressure columns, thereby preventing the fabric from being pulled and undulated due to embroidery, improving embroidery efficiency, and ensuring the quality of the embroidery product.

[0004] However, in actual use, the above technical solution uses rubber pressure pins to compact the fabric, which is linear compaction, so the contact area with the fabric is small. Therefore, when the fabric is subjected to a large pull and fluctuates, the fabric may still move, thereby affecting the embroidery effect. At the same time, since the rubber pressure pins rotate to flatten the fabric, it is difficult to ensure the pulling force on it, which can easily cause the fabric to be deformed and damaged by a large pull.

[0005] For this reason, a cloth pressing device of an embroidery machine is proposed. Utility Model Content

[0006] In order to solve the problems existing in the prior art, the utility model provides a cloth pressing device for an embroidery machine.

[0026] like Figure 1-5As shown, a cloth pressing device of an embroidery machine includes an embroidery machine frame 1, an embroidery machine head 3 is provided on the embroidery machine frame 1, a cloth 4 is placed on the embroidery machine frame 1, and two cloth pressing components 5 for pressing the cloth 4 are provided on the embroidery machine frame 1. The cloth pressing components 5 include a compacting member 6 and a flattening member 7. The compacting member 6 includes an electric telescopic rod 601 provided at the top of the embroidery machine frame 1. The telescopic end of the electric telescopic rod 601 is connected to a pressure sensor 602. The top of the pressure sensor 602 is provided with a mounting plate 603. The flattening member 7 It includes two slide rails 701 arranged at the bottom of the mounting plate 603, and a connecting plate 705 is slidably provided at the bottom of the two slide rails 701. A vacuum generator 706 is provided on the top of the connecting plate 705. The output end of the vacuum generator 706 is connected to a connecting pipe 707. The bottom end of the connecting pipe 707 is provided with a vacuum suction plate 708, and a suction hole 709 is opened on the vacuum suction plate 708. Specifically, the cloth 4 is placed on the embroidery machine frame 1, and its position is preliminarily arranged. Then, the compacting component 6 provided thereafter can drive the leveling component 7 to descend. The vacuum generator 706 is operated so that the negative pressure of the vacuum suction plate 708 has a certain adsorption effect on the fabric. Then the motor 703 is operated to drive the screw rod 702 to rotate, thereby driving the slider 704 to slide, and then driving the connecting plate 705 to slide, so as to flatten the leather material. Since the fabric 4 is breathable, the adsorption effect on it is limited, so it will not cause a large pulling effect on it, avoiding excessive stretching and deformation. During stretching, only the wrinkles on its surface can be flattened. After it is flattened, the compacting member 6 is able to compact both sides of the fabric 4, making it convenient for embroidery processing. When embroidery is done, the embroidery effect will not be affected by wrinkles. At the same time, when compacting, the pressure sensor 602 is able to detect the compaction force. When it is detected that the pressure reaches the set value, it will send a signal to the external controller, and the controller will control the electric telescopic rod 601 to stop extending. Since the vacuum suction plate 708 is in surface contact with the fabric 4 during compaction, the compaction effect is better.

[0027] like Figure 1 As shown, an embroidery slot 101 is provided on the embroidery machine frame 1, and two cloth pressing assemblies 5 are respectively distributed on both sides of the embroidery slot 101; specifically, the embroidery machine head 3 is arranged above the embroidery slot 101 to facilitate embroidery processing. The embroidery machine is a prior art, so the structure of the embroidery machine head 3 on the embroidery machine is not described in detail here.

[0028] like Figure 1 As shown, four supporting legs 2 are provided at the bottom end of the embroidery machine frame 1 , and anti-slip pads 201 are provided at the bottom ends of the supporting legs 2 .

[0029] like Figure 4 and 5As shown, a screw rod 702 is rotatably provided inside each of the two slide rails 701, a motor 703 is provided on one side of one of the slide rails 701, and one of the screw rods 702 is connected to the main shaft end of the motor 703; specifically, the motor 703 can drive the screw rod 702 to rotate when it works, thereby driving the slider 704 to slide.

[0030] like Figure 4 and 5 As shown, a slider 704 is provided for sliding inside the slide rail 701 , the slider 704 is threadedly sleeved on the screw rod 702 , and the connecting plate 705 is connected to the slider 704 ; specifically, the sliding of the slider 704 can drive the connecting plate 705 to slide.

[0031] like Figure 4 and 5 As shown, one end of one of the screw rods 702 is connected to the first pulley 710, and the other main shaft end of the motor 703 is connected to the second pulley 711, and a belt 712 is provided for transmission between the first pulley 710 and the second pulley 711; specifically, the motor 703 can drive the second pulley 711 to rotate when it is working, and under the transmission action of the belt 712, the first pulley 710 can be driven to rotate, thereby driving the other screw rod 702 to rotate, so that the two sliders 704 can slide at the same time, and since the connecting plate 705 is supported at two points, the movement can be more stable.

[0032] In summary: the pressure sensor 602 and the vacuum generator 706 are both existing technologies, so their principles, structures and models are not described in detail here. In specific use, the cloth 4 is placed on the embroidery machine frame 1, and its position is preliminarily arranged. Then the compacting member 6 can drive the flattening member 7 to descend, so that the vacuum generator 706 works and the negative pressure of the vacuum suction plate 708 has a certain adsorption effect on the cloth. Then the motor 703 works to drive the screw rod 702 to rotate, thereby driving the slider 704 to slide, and then driving the connecting plate 705 to slide, so as to flatten the leather material. Since the cloth 4 is breathable, it is sucked The attachment effect is limited, so it will not cause a large pulling effect on it, avoiding its deformation due to excessive stretching. When stretching, it can only flatten the wrinkles on its surface. After it is flattened, the compacting member 6 can compact both sides of the cloth 4, which is convenient for embroidery processing. The embroidery effect will not be affected by the wrinkles during embroidery. At the same time, when compacting it, the pressure sensor 602 can detect the compaction force. When it is detected that the pressure reaches the set value, it will send a signal to the external controller, and the controller will control the electric telescopic rod 601 to stop extending. Since the vacuum suction plate 708 is in surface contact with the cloth 4 during compaction, the compaction effect is better.

[0033] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention.
