[0033] Example
[0034] Reference Figure 1 and Figure 2 As shown, this embodiment provides a marking mechanism for an air film waterproof curtain, including a workbench 1, a limit clamp 2 and a marking assembly 3. Specifically, the workbench 1 can be installed on a frame 4, and the frame 4 can be a hexahedral skeleton structure composed of multiple rod structures, so that the workbench 1 is separated from the ground. The limit clamp 2 is installed on the workbench 1, and is used to accommodate the waterproof curtain to pass through and position the waterproof curtain. Specifically, a winding device and an unwinding device can also be installed at both ends of the frame 4, so that the rolled waterproof curtain membrane passes through the workbench 1 and moves under the action of the winding device and the unwinding device. It should be noted that although the winding device and the unwinding device are not shown in the figure, they belong to conventional technical means that those skilled in the art should know. In other embodiments, manual winding and unwinding can also be used to drive the waterproof curtain to move.
[0035] Reference Figure 2 As shown, the marking assembly 3 includes a mounting ear 31, a threaded rod 32 and a marking pen 33. The two mounting ears 31 are mounted on the workbench 1. The threaded rod 32 passes through the two mounting ears 31 in sequence, so that the threaded rod 32 can move relative to the mounting ears 31. Two positioning nuts 34 are connected to the threaded rod 32. The two positioning nuts 34 are respectively located on the inner sides of the two mounting ears 31. The positioning nuts 34 abut against the mounting ears 31 to limit the axial direction of the threaded rod 32. The marking pen 33 is connected to the threaded rod 32, and the tip of the marking pen 33 contacts the surface of the waterproof curtain. When the waterproof curtain moves, the tip of the marking pen 33 marks the waterproof curtain. When the marking position on the waterproof curtain needs to be changed, the axial position of the threaded rod 32 can be changed by adjusting the positioning nuts 34, and then the positioning nuts 34 are used for positioning, thereby changing the position of the marking pen 33.
[0036] The marking mechanism of the air film waterproof curtain provided in this embodiment can mark the waterproof curtain continuously when the waterproof curtain passes the position where the marking pen 33 is located during the movement of the waterproof curtain, so as to provide a limit mark for the subsequent sewing of the Velcro; and the position of the marking pen 33 can be adjusted by adjusting the position of the threaded rod 32, so that the marking position can be adjusted to meet the marking requirements of different widths. The marking structure provided by the utility model is simple in structure and low in cost.
[0037] Specifically, the marking assembly 3 also includes a pre-tightening member 35, referring to Figure 3 As shown, the pre-tightening member 35 includes a pre-tightening nut 351, a pressure plate 352 and an elastic member 353. The pre-tightening nut 351 is connected to the threaded rod 32, the pressure plate 352 is connected to the pre-tightening nut 351, and one end of the elastic member 353 is connected to the pressure plate 352 and the other end is connected to the workbench 1. In this embodiment, the threaded rod 32 is located obliquely above the limit assembly, so that the marking pen 33 is arranged obliquely from the positioning rod to the waterproof curtain, and the elastic member 353 has an elastic force that moves the pressure plate 352 toward the workbench 1. Under the action of the elastic member 353, the threaded rod 32 has a tendency to rotate, so that the tip of the marking pen 33 is pressed against the waterproof curtain, ensuring the stability of the marking process and the quality of the marking. Specifically, the elastic member 353 can be a spring.
[0038] Specifically, the marking assembly 3 includes two sets of pre-tightening members 35, which are respectively installed at the two ends of the threaded rod 32 to ensure the balance of the pre-tightening force of the marking pen 33.
[0039] Specifically, the position-limiting clamp 2 includes two first clamps 21 and two second clamps 22; the two first clamps 21 are arranged in parallel and installed on the workbench 1, and a passage for accommodating the waterproof curtain is formed between the two first clamps 21, so that the two edges of the waterproof curtain are respectively against the two first clamps 21, thereby positioning the width direction of the waterproof curtain. Each of the second clamps 22 is respectively connected to the two first clamps 21, and the two second clamps 22 are parallel to each other, and the second clamps 22 press the waterproof curtain to limit the vertical position of the waterproof curtain.
[0040] Specifically, the workbench 1 is provided with a first adjustment slot 23, the first clamping plate 21 is provided with a through hole, and the second clamping plate 22 is provided with a second adjustment slot 24; the mounting bolt (not shown) passes through the second adjustment slot 24, the through hole and the first adjustment slot 23 in sequence to lock the first clamping plate 21 and the second clamping plate 22 on the workbench 1; the first adjustment slot 23 extends along the width direction of the channel, and the second adjustment slot 24 extends in the same direction as the first adjustment slot 23. By adjusting the position of the mounting bolt along the direction of the adjustment slot, the position of the first clamping plate 21 can be adjusted to limit the waterproof curtains of different widths.
[0041] Specifically, refer to Figure 4 As shown, the marking pen 33 includes a pen cover 331 and a pen core 332. The pen cover 331 is provided with an installation space, and the installation space includes a first opening, a receiving space, and a second opening. The diameter of the second opening is smaller than the diameter of the receiving space so that the tip of the pen core 332 extends outward from the second opening. A plug 333 is connected to the first opening. The plug 333 abuts against the tail end of the pen core 332. The plug 333 can be threadedly connected to the first opening. The pen core 332 can be quickly replaced by unscrewing the plug 333, and the depth of screwing the plug 333 into the pen cover 331 can be adjusted to accommodate pen cores 332 of different lengths.
[0042] Specifically, a bayonet 334 is provided on the outside of the pen cap 331. In this embodiment, the pen cap 331 is made of metal. After the bayonet 334 is engaged with the threaded rod 32, the pen cap 331 and the threaded rod 32 are welded to ensure the stability between the pen cap 331 and the threaded rod 32. The pen cap 331 and the threaded rod 32 can also be connected by bonding. In other embodiments, the material of the pen cap 331 can also be non-metallic material, and other mechanical connection methods are used to connect with the threaded rod 32.
[0043] Usage process: adjust the position of the first clamping plate 21 to adapt it to the width of the waterproof curtain, adjust the position of the threaded rod 32 to make the marking pen 33 reach the specified marking position, and make the waterproof curtain pass under the limiting clamp 2. While moving the waterproof curtain, the marking pen 33 marks the waterproof curtain.
[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0045] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
