Description

Technical Field

[0001] This utility model relates to the field of garment processing equipment technology, and in particular to an adjustable positioning clamp for sewing woven labels. Background Technology

[0002] In the garment production and processing process, sewing woven labels is a common and important step. In order to ensure sewing quality and efficiency, positioning clamps are usually used to temporarily fix the woven labels and garment fabric on the sewing machine worktable to prevent displacement during high-speed sewing and ensure the accuracy of the sewing thread trajectory.

[0003] Most existing positioning fixtures have simple structures and single functions. For example, some magnetic or screw-fixed fixtures are not easy to change once their position on the worktable is determined. When it is necessary to change the sewing position of the woven label on the garment, the operator must spend time disassembling and recalibrating the fixture, which is cumbersome and seriously affects production efficiency.

[0004] Furthermore, woven labels come in a wide variety of sizes and widths, while traditional clamps typically have a fixed clamping width, making them unadjustable for different widths. This results in either ineffective clamping or frequent replacement of clamps with different sizes, increasing equipment costs and management complexity for businesses. Consequently, existing clamps generally suffer from structural defects such as poor applicability and inconvenient adjustment.

[0005] Therefore, this utility model proposes an adjustable positioning clamp for sewing woven labels to overcome the shortcomings of the prior art. Summary of the Invention

[0006] In view of the problems of existing woven label sewing clamps, such as the single clamping width, inability to adapt to different sizes of woven labels, and fixed overall position, making it difficult to quickly align with the sewing start point, this utility model aims to provide an adjustable positioning clamp for woven label sewing with an improved structure that can effectively solve the above problems.

[0007] This utility model provides an adjustable positioning clamp for sewing woven labels, including: a clamping assembly, which includes a saw-shaped guide strip, a first outer shell, and a second outer shell; and a cutting board assembly, which includes a saw-shaped strip.

[0008] The first outer shell is slidably connected to the saw-shaped guide bar, the second outer shell is fixedly connected to one side of the first outer shell, and the saw-shaped guide bar is slidably inserted into the second outer shell.

[0009] Furthermore, a slider is provided inside the first housing, which slides in conjunction with the saw-shaped guide bar. A spring plate is fixed on the slider, and a push key is provided on the first housing, which abuts against the spring plate. A torsion bar is rotatably connected inside the first housing, and a stop plate is fixed on the torsion bar. The stop plate is driven by the torsion spring and inserted into the saw groove of the saw-shaped bar. A pressure plate is rotatably connected below the saw-shaped guide bar.

[0010] Preferably, a connecting rod is hinged to the end of the sawtooth strip away from the second housing, and a guide plate is slidably connected to the connecting rod.

[0011] Preferably, the length of the pressure plate extends above the guide plate, and the pressure plate can rotate toward the guide plate to press the woven label placed on the guide plate.

[0012] Preferably, the push button is slidably connected to the side wall of the first housing, and the inner end of the push button abuts against the free end of the spring sheet.

[0013] Preferably, one end of the torsion spring is connected to the bottom surface of the first housing, and the other end is connected to the stop plate.

[0014] Preferably, the connecting rod and the saw blade are hinged by a pin, allowing the connecting rod to swing relative to the saw blade.

[0015] Preferably, a groove structure is provided between the guide plate and the connecting rod, and the guide plate can move along the length direction of the connecting rod.

[0016] Preferably, the first outer shell and the second outer shell are internally connected to form a cavity for accommodating the sliding of the saw blade.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example: Please refer to Figures 1 to 4 This utility model provides an adjustable positioning clamp for sewing woven labels, which aims to solve the problems of fixed clamp structure, inability to adjust clamping width and overall position at the same time, and poor applicability in the prior art.

[0028] like Figure 1 and Figure 2As shown, the adjustable positioning clamp for sewing woven labels includes a clamping assembly 1 and a cutting board assembly 2. The clamping assembly 1 includes a saw-shaped guide 104, a first outer shell 101, and a second outer shell 102. The first outer shell 101 is slidably connected to the saw-shaped guide 104, and the second outer shell 102 is fixedly connected to one side of the first outer shell 101. The cutting board assembly 2 includes a saw-shaped strip 202, which is slidably inserted into the second outer shell 102. The first outer shell 101 and the second outer shell 102 are internally connected to form a cavity for accommodating the sliding of the saw-shaped strip 202. A slider 107 is provided inside the first outer shell 101, and the slider 107 is slidably engaged with the saw-shaped guide 104. A spring plate 106 is fixed on the slider 107. A push button 103 is provided on the first outer shell 101. The push button 103 is slidably connected to the side wall of the first housing 101. The inner end of the push button 103 abuts against the free end of the spring plate 106. When the push button 103 is pushed outward, the spring plate 106 is lifted to control the locking state of the slider 107 and the saw-shaped guide 104. In order to achieve width adjustment, a torsion bar 204 is rotatably connected inside the first housing 101. A stop plate 206 is fixed on the torsion bar 204. One end of the torsion spring 205 is connected to the bottom surface of the first housing 101, and the other end of the torsion spring 205 is connected to the stop plate 206. The stop plate 206 is driven by the torsion spring 205 and inserted into the saw groove of the saw-shaped bar 202. The pressing assembly 1 also includes a pressure plate 105, which is rotatably connected to the bottom of the saw-shaped guide 104.

[0029] The core of the technical solution in this embodiment lies in the specific adjustment structures provided in the pressing component 1 and the cutting board component 2. Please refer to them carefully. Figure 1 and Figure 2 The structure used for overall position adjustment is described in detail below:

[0030] The position adjustment mechanism includes a slider 107 disposed within the first housing 101, a spring plate 106 fixedly connected to the slider 107, and a push key 103 slidably connected to the first housing 101. The slider 107 is slidably engaged with the saw-shaped guide 104. The free end of the spring plate 106 is used to apply a force that causes friction between the slider 107 and the saw-shaped guide 104, thereby achieving locking. At the same time, the push key 103 is correspondingly disposed on the side wall of the first housing 101, and the inner end of the push key 103 abuts against the free end of the spring plate 106. This engagement structure of push key 103-spring plate 106-slider 107 ensures that when the push key 103 is pushed outward, the inner end of the push key 103 lifts the free end of the spring plate 106, thereby reducing the force between the slider 107 and the saw-shaped guide 104, allowing the first housing 101 to slide along the saw-shaped guide 104, thereby achieving overall position adjustment of the fixture.

[0031] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0032] A connecting rod 201 is hinged to one end of the saw blade 202 away from the second outer shell 102. The connecting rod 201 and the saw blade 202 are hinged by a pin, so that the connecting rod 201 can swing relative to the saw blade 202. A guide plate 203 is slidably connected to the connecting rod 201. A groove structure is provided between the guide plate 203 and the connecting rod 201. The guide plate 203 moves along the length direction of the connecting rod 201.

[0033] In a preferred embodiment, the pressure plate 105 extends above the guide plate 203, and the pressure plate 105 rotates in the direction of the guide plate 203 to press the woven label placed on the guide plate 203.

[0034] In a preferred embodiment, the push key 103 is slidably connected to the side wall of the first housing 101, and the inner end of the push key 103 abuts against the free end of the spring sheet 106. When the push key 103 is pushed outward, the spring sheet 106 is lifted.

[0035] In a preferred embodiment, one end of the torsion spring 205 is connected to the bottom surface of the first housing 101, and the other end is connected to the stop plate 206.

[0036] Working principle: When the overall position of the clamp needs to be adjusted, push the push key 103 on the first housing 101 outward. The inner end of the push key 103 abuts against and lifts the spring plate 106. The spring plate 106 releases the frictional force on the slider 107, causing the slider 107 to separate from the saw-shaped guide 104. At this time, the first housing 101 drives the second housing 102 and the cutting board assembly 2 to slide along the saw-shaped guide 104 to the predetermined position. Release the push key 103. The spring plate 106 resets under its own elastic force, driving the slider 107 to lock and fix with the saw-shaped guide 104.

[0037] When the clamping width needs to be adjusted, rotate the torsion bar 204 inside the first housing 101. The torsion bar 204 drives the fixedly connected stop plate 206 to rotate. The stop plate 206 overcomes the elastic force of the torsion spring 205 and disengages from the saw groove of the saw blade 202. At this time, pull or push the connecting rod 201. The connecting rod 201 drives the saw blade 202 to slide inside the second housing 102. The telescopic guide plate 203 moves with the connecting rod 201. After adjusting to the appropriate width, release the torsion bar 204. The torsion spring 205 drives the stop plate 206 to automatically engage in the saw groove of the saw blade 202 to complete the width locking.

[0038] After adjustment, place the woven label on the guide plate 203 and rotate the pressure plate 105 connected to the bottom of the saw-shaped guide bar 104. The pressure plate 105 flips down and presses the woven label on the guide plate 203 to achieve precise positioning and clamping.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
