Description

Technical Field

[0001] This utility model relates to the field of sewing equipment technology, and specifically to a suction device with a fast valve. Background Technology

[0002] In the use of template sewing machines, some special sewing processes are encountered, such as sewing pockets. Traditional pocket sewing requires folding the pocket edges first, and then ironing the folds flat to prevent them from curling up during subsequent sewing, affecting the sewing process. In the new sewing process, a suction table is needed to hold the pocket edges in place, ensuring their flatness. The conventional fabric laying process cannot lay the fabric flat on the template. Therefore, when encountering processes that require flatness of the fabric during laying, an external suction laying table is often needed. The fabric is laid on the suction laying table to achieve the required flatness. Traditional suction laying tables typically use a high-pressure turbine fan as a power source, and the negative pressure generated by the power source is transmitted to the suction laying table through pipes to suck up the fabric, making it flat and fixed. After sewing is completed, the high-pressure turbine fan needs to be stopped to allow the fabric to be removed from the worktable. This results in frequent starts and stops of the high-pressure turbine fan, high energy consumption, easy damage, and a short service life. Utility Model Content

[0003] The purpose of this invention is to provide a suction device with a fast valve, which solves the problem of frequent fan starts.

[0004] The purpose of this utility model is achieved as follows: A suction device with a fast valve includes a suction chamber, a pipe joint for connecting a fan is provided on the lower end face of the suction chamber, an air passage cavity is formed inside the suction chamber, an air inlet is provided on the upper end face of the suction chamber, a baffle plate is installed at the air inlet, an air inlet is provided on the lower end face of the suction chamber, a baffle plate is installed at the air inlet, a rotating shaft is connected between the baffle plate and the baffle plate, and a power source for controlling the rotation of the baffle plate is connected to one end of the baffle plate to open or close the air inlet.

[0005] Preferably, a slot is provided on the side wall of the rotating shaft, a first locking block is provided on the inner circumference of the first wind deflector, and a second locking block is provided on the inner circumference of the second wind deflector.

[0006] Preferably, a fixing component is installed at each end of the rotating shaft, a gasket is provided between the fixing component and the rotating shaft, and a spring abuts between the gasket and the wind deflector.

[0007] Preferably, one end of the wind deflector one or wind deflector two is connected to a pull rod, the other end of the pull rod is connected to a power source, a connecting part one is formed on one side of the pull rod, a connecting part two is provided on the lower end face of the air suction chamber, and a tension spring is connected between the connecting part two and the connecting part one.

[0008] Preferably, the power source is an electromagnet.

[0009] Preferably, the first wind deflector and the second wind deflector are respectively provided with a wind passage hole and a wind-blocking part.

[0010] Preferably, the upper surface of the air intake chamber is equipped with an installation plate, and the installation plate has an installation hole that communicates with the air inlet.

[0011] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0012] This invention places the suction chamber below the fabric laying table. After the pipe joint is connected to the fan, the fan draws air from the suction chamber, creating negative pressure. When the baffle plate is rotated to open the air inlet, the negative pressure in the suction chamber can adsorb the material on the upper part of the fabric laying table, thus laying it flat and fixing it. When the baffle plate is rotated to open the air inlet and close the air inlet, the negative pressure in the suction chamber no longer adsorbs the material on the upper part of the fabric laying table, so that the sewn fabric can be easily removed. This avoids frequent starting of the fan, saving energy and reducing consumption. Attached Figure Description

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-4 As shown, a suction device with a fast valve includes a suction chamber 1, a pipe joint 2 for connecting a fan is provided on the lower end face of the suction chamber 1, an air passage cavity 3 is formed inside the suction chamber 1, an air inlet 4 is provided on the upper end face of the suction chamber 1, a baffle plate 5 is installed at the air inlet 4, an air inlet 6 is provided on the lower end face of the suction chamber 1, a baffle plate 7 is installed at the air inlet 6, a rotating shaft 8 is connected between the baffle plate 5 and the baffle plate 7, and a power source 9 for controlling the rotation of the baffle plate 5 or the baffle plate 7 is connected to one end of the baffle plate 5 or the baffle plate 7 to open or close the air inlet.

[0022] This invention places the suction chamber below the fabric laying table. After the pipe joint 2 is connected to the fan, the fan draws air from the suction chamber, creating negative pressure. When the baffle plate is rotated to open the air inlet 4, the negative pressure in the suction chamber can adsorb the material on the upper part of the fabric laying table, thus laying it flat and fixing it. When the baffle plate is rotated to open the air inlet 4 and close the air inlet 6, the negative pressure in the suction chamber no longer adsorbs the material on the upper part of the fabric laying table, making it easier to remove the sewn fabric. This avoids frequent starting of the fan, saving energy and reducing consumption.

[0023] A slot 10 is provided on the side wall of the rotating shaft 8, a locking block 11 is provided on the inner circumference of the first wind deflector 5, and a locking block 12 is provided on the inner circumference of the second wind deflector 7. The connection between the rotating shaft and the wind deflector is realized through the cooperation of the slot and the locking block. When any one wind deflector rotates, the other wind deflector will also rotate at the same time through the rotating shaft, thereby realizing the opening of the first air inlet 4 while closing the second air inlet 6, or closing the first air inlet 4 while opening the second air inlet 6.

[0024] Fixing members 13 are installed at both ends of the rotating shaft 8. A gasket 14 is provided between the fixing member 13 and the rotating shaft 8. A spring 15 abuts against the wind baffle. The action of the spring 15 can keep the wind baffle against the end face of the air intake chamber, thereby closing the air inlet and preventing leakage.

[0025] One end of the wind deflector 5 or the wind deflector 7 is connected to a pull rod 16, and the other end of the pull rod 16 is connected to a power source 9. A connecting part 17 is formed on one side of the pull rod 16, and a connecting part 28 is provided on the lower end face of the air suction chamber 1. A tension spring 19 is connected between the connecting part 218 and the connecting part 17 to achieve an automatic reset effect.

[0026] The power source 9 is an electromagnet.

[0027] The wind deflector 5 and the wind deflector 7 are respectively provided with a wind hole 20 and a wind deflection part 21.

[0028] The upper surface of the air intake chamber 1 is equipped with an installation plate 22, and the installation plate 22 has an installation hole 23 that communicates with the air inlet 4.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
