[0035] The utility model discloses a position adjustment structure of a clamping hook control switch, such as Figures 1 to 3As shown in the figure, the position adjustment structure is arranged in a sewing device with an automatic feeding device having an adjustable spacing between the clamping hooks 5, and is close to the clamping area 501 of the automatic feeding device. The position adjustment structure includes:

[0036] The switch mounting block 1 is detachably connected to the workbench 2 outside the clamping area 501. The workbench 2 above the switch mounting block 1 is provided with a through hole 201. The top of the switch mounting block 1 is a boss 101 extending into the through hole 201.

[0037] The switch 102 is arranged on the switch mounting block 1 at the position of the boss 101;

[0038] The limiting block 3 is detachably engaged in the through hole 201 outside the boss 101 , and cooperates with the boss 101 to fill the space in the through hole 201 .

[0039] It should be noted that, when the automatic feeding device on the sewing machine can adjust the spacing between the clamping hooks 5, the clamping hooks 5 on the automatic feeding device that can adjust the position need to be moved a certain distance in the direction away from the processing device of the sewing equipment to adapt to the length of the material so as to facilitate its clamping and transmission; moreover, a switch 102 for controlling the automatic feeding device is provided outside the clamping area 501 of the automatic feeding device, which can facilitate the operator to operate the switch 102 for controlling the clamping hooks 5 after placing the material at a specified position on the surface of the workbench 2, thereby clamping the material by controlling the clamping hooks 5. After the clamping hooks 5 clamp the material, another switch 102 is operated to control the automatic feeding device to start transmitting the material to the processing device of the sewing machine for sewing processing. It can be seen that the switch device for controlling the operation of the automatic feeding device on the surface of the workbench 2 is provided, which helps to improve the smoothness of the sewing processing operation of the sewing machine.

[0040] However, the switch device arranged on the surface of the workbench 2 for controlling the operation of the automatic feeding device must be close to the area where the clamping hook 5 of the automatic feeding device clamps the material in order for this structure to play its advantages, and the area where the clamping hook 5 clamps the material after the position is adjusted may interfere with the operation of the switch 102; for this reason, the position adjustment structure can adjust the position of the switch 102 for controlling the operation of the automatic feeding device by adjusting the connection position of the switch mounting block 1 on the workbench 2, so as to avoid the position of the clamping hook 5 after adjusting to a larger clamping distance being too close to the switch 102 located on the surface of the workbench 2 and affecting the operation of the operator; in addition, when the boss 101 is connected to the workbench 2, the position of the clamping hook 5 is adjusted to a larger clamping distance. After one end of the hole 201 moves to the other end, the portion of the through hole 201 located outside the boss 101 is vacant, which will cause the surface of the workbench 2 to be uneven. The limit block 3 is used to fill the portion of the through hole 201 outside the boss 101 after the switch 102 is adjusted, so that the surface of the workbench 2 remains flat while also limiting the position of the boss 101, thereby fixing the position of the switch mounting block 1; after the position of the switch 102 is adjusted, there is a distance between the position of the switch 102 and the position of the clamping area 501, so that the action of the clamping hook 5 when clamping the material will not affect the operator's loading during material transmission and the operation of controlling the clamping hook to clamp the material.

[0041] As one of the embodiments of the present utility model, Figure 3 and Figure 4 As shown in combination, the workbench 2 outside the through hole 201 is provided with at least one or more mounting holes 1 202, and the portion of the switch mounting block 1 located below the mounting holes 1 202 is provided with at least one or more mounting holes 2 103; by installing connecting components into the mounting holes 1 202 and the mounting holes 2 103 corresponding to each other in the vertical direction, the switch mounting block 1 is fixed to the surface of the workbench 2 below the mounting holes 1 202, so as to fix the position of the switch 102 after the position adjustment.

[0042] As a further preference of the above embodiment, Figure 4 As shown, the number of the second mounting holes 103 is greater than the number of the first mounting holes 202 .

[0043] Among them, since the position adjustment of the switch 102 involves the position adjustment of the switch mounting block 1, and the setting position of the switch 102 is located in the area where the boss 101 is located, when the boss 101 moves from one end of the through hole 201 to the other end, a part of the switch mounting block 1 will move to the surface of the workbench 2 outside the material transmission direction of the through hole 201. If the number of the second mounting holes 103 set on the switch mounting block 1 is the same as the number of the first mounting holes 202, the second mounting holes 103 moved to the surface of the workbench 2 outside the material transmission direction of the through hole 201, and the surface of the workbench 2 above it is not There is no mounting hole 102 corresponding to the position of the mounting hole 103, so that the connecting component cannot be installed at this position for fixing, resulting in a difference in the fixing effect of the switch mounting block 1 before and after the movement, which will affect the fixing effect of the switch mounting block 1 on the workbench 2. Therefore, the number of mounting holes 103 is greater than the number of mounting holes 102, which can ensure that after the switch mounting block 1 is moved, there is still a mounting hole 103 corresponding to the position of the mounting hole 1 202 on the other end of the switch mounting block 1, so as to maintain the fixing effect of the switch mounting block 1 before and after the position is moved.

[0044] As a further preference of the above embodiment, Figures 5 to 7 As shown in the figure, the mounting hole 1 202 and / or the mounting hole 2 103 are waist-shaped holes.

[0045] Among them, when the mounting hole 1 202 is a waist-shaped hole and the mounting hole 2 103 is an ordinary connecting component matching hole, the position of the connecting component installed in the mounting hole 1 202 and the mounting hole 2 103 can be determined according to the position of the mounting hole 2 103; when the mounting hole 1 202 is an ordinary connecting component matching hole and the mounting hole 2 103 is a waist-shaped hole, the position of the connecting component installed in the mounting hole 1 202 and the mounting hole 2 103 can be determined according to the position of the mounting hole 1 202; and when the mounting hole 1 202 and the mounting hole 2 103 are both waist-shaped holes, the connecting component can be installed as long as corresponding positions in the height direction are formed in the mounting hole 1 202 and the mounting hole 2 103, and a connecting component with a nut is required to ensure the tightness of the connection after the connecting component is installed in the mounting hole 1 202 and the mounting hole 2 103. The position of the nut is located below the mounting hole 2 or in the mounting hole 1 202 whose height does not exceed the surface height of the workbench 2, so as not to affect the flatness of the surface of the workbench 2.

[0046] As one of the embodiments of the present utility model, Figure 2 and Figure 3 As shown in the combination, the limit block 3 is provided with a mounting hole three 301, and the portion of the switch mounting block 1 located below the mounting hole three 301 is provided with a mounting hole four 104 corresponding to the mounting hole three 301.

[0047] Among them, by installing connecting components to the corresponding mounting holes 301 and 4 104 in the height direction, the limit block 3 can be detachably connected to the switch mounting block 1 to form a whole. No matter which end of the through hole 201 the boss 101 is located in, the limit block 3 can be connected to the surface of the switch mounting block 1 outside the boss 101, and cooperate with the boss 101 to fill the empty space in the through hole 201.

[0048] As a further preference of the above embodiment, Figure 8 and Fig. 9 As shown in the figure, the switch mounting blocks 1 outside the two sides of the boss 101 are provided with mounting holes 104.

[0049] Among them, in order to prevent the switch mounting block 1 from being unable to install the limit block 3 at the other end of the switch mounting block 1 in the length direction when the through hole 201 is moved to the surface of the workbench 2 outside the material transmission direction, mounting holes 104 are set at both ends of the switch mounting block 1 in the length direction. After the position of the switch 102 is adjusted, the other end of the switch mounting block 1 still has a mounting hole 104 corresponding to the position of the mounting hole 301, so as to ensure that the limit block 3 can be connected to the switch mounting block 1.

[0050] As a further preference of the above embodiment, Fig.10 As shown, the mounting hole 4 104 is a waist-shaped hole.

[0051] Among them, when the mounting hole four 104 is a waist-shaped hole, as long as the mounting hole three 301 corresponds to the position of the mounting hole four 104 in the opposite height, the connecting component can be installed into the mounting hole three 301 and the mounting hole four 104, so that the limit block 3 is connected to the switch mounting block 1, and the operation of aligning the mounting hole three 301 and the mounting hole four 104 is simpler than the operation when the mounting hole four 104 is a circular mounting hole.

[0052] As one of the embodiments of the present utility model, Figures 11 to 14 As shown in the figure, the number of the limiting blocks 3 matched in the through hole 201 is more than one, and all the limiting blocks 3 are matched in the through hole 201 outside any end of the boss 101 or respectively matched in the through holes 201 outside the two ends of the boss 101.

[0053] Among them, because the position of the through hole 201 on the workbench 2 is fixed, the position of the clamping hook 5 will be located near the center side of the through hole 201 after the position of the material of a certain length is adjusted. At this time, the through holes 201 outside the two ends of the boss 101 are vacant, and a single fixed-length limit block 3 cannot fill the through holes 201 outside the two ends of the boss 101 at the same time. At this time, multiple limit blocks 3 are needed to be used in conjunction. Multiple limit blocks 3 can be used to respectively cooperate in the through holes 201 outside the two ends of the boss 101 for filling. When the boss 101 is close to the end of the through hole 201, it can also be placed in the through hole 201 outside any end of the boss 101 for filling. Moreover, the coordinated use of multiple limit blocks 3 can make the distance between the position of the switch 102 and the clamping hook 5 more accurately controlled to meet the habitual needs of different operators during operation.

[0054] As one of the embodiments of the present utility model, Figures 11 to 14 As shown in combination, the limit block 3 in the through hole 201 that is closest to the end of the boss 101 has a contour close to the end of the boss 101 that is the same as the contour of the end of the boss 101; the limit block 3 that is closest to the end of the through hole 201 has an end contour that is the same as the contour of the end of the through hole 201.

[0055] Among them, the contours of the limit blocks 3 installed at the two ends of the vacant positions in the through hole 201 need to correspond to the contours of the ends of the boss 101 and the ends of the through hole 201, so as to fill the vacancy in the through hole 201 without any gaps, thereby ensuring the fixing effect on the position of the boss 101.

[0056] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
