[0026] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0027] Example Please see Figure 1 , Figure 1 The diagram shown is a partial structural schematic of the Velcro sewing device 200 provided in this embodiment.

[0028] The Velcro sewing equipment 200 provided in this embodiment includes a work platform 210, a drive device 220, a Velcro clamp 100, a sewing device 240, and a laser cutting device 250. The drive device 220, the Velcro clamp 100, the sewing device 240, and the laser cutting device 250 are all mounted on the work platform 210.

[0029] The hook and loop clamp 100 is used to clamp the free end of the hook and loop material strip 300. The drive device 220 is connected to the hook and loop clamp 100 to drive the hook and loop clamp 100 to reciprocate along the first horizontal direction, thereby driving the hook and loop material strip 300 to be fed on the work platform 210 along the first horizontal direction.

[0030] The laser cutting device 250 is used to cut the hook and loop fastener tape 300, and the sewing device 240 is used to sew the cut portion of the hook and loop fastener tape 300 to the object to be sewn.

[0031] The first horizontal direction is Figure 1 The direction indicated by the X arrow in the diagram actually means that the drive device 220 can also drive the Velcro clamp 100 to reciprocate along a second horizontal direction, which is... Figure 1 The direction indicated by the Y-arrow. Preferably, in this embodiment, the first horizontal direction is perpendicular to the second horizontal direction.

[0032] The hook and loop fastener sewing equipment 200 provided in this embodiment also includes an unwinding device 230, which is also disposed on the work platform 210 and is used to unwind the hook and loop fastener tape 300. In practical applications, the hook and loop fastener tape 300 unwound by the unwinding device 230 has its free end clamped and fixed by the hook and loop fastener clamp 100. As the driving device 220 drives the hook and loop fastener clamp 100 to move along the first horizontal direction, the unwinding device 230 continuously unwinds the tape, thereby realizing the feeding of the hook and loop fastener tape 300.

[0033] Please refer to the following: Figure 2 , Figure 3 and Figure 4 , Figure 2 The diagram shows the structure of the Velcro clamp 100 mounted on the work platform 210. Figure 3 The diagram shown is a structural schematic of the Velcro clip 100. Figure 4 As shown Figure 3 An enlarged schematic diagram of region A in the middle.

[0034] In this embodiment, the hook and loop clamp 100 includes a support base plate 110 and a clamping mechanism 120. The support base plate 110 is laid on the surface of the work platform 210 and connected to the drive device 220. The clamping mechanism 120 is disposed on the support base plate 110 and is used to clamp the hook and loop material strip 300 together with the support base plate 110.

[0035] In practical applications, the operator can pull the free end of the hook and loop tape 300 along the first horizontal direction and place it on the supporting base plate 110, so that the clamping mechanism 120 and the supporting base plate 110 jointly clamp and fix the free end of the hook and loop tape 300. In this state, the drive device 220 can drive the supporting base plate 110 to move along the first horizontal direction, thereby driving the clamping mechanism 120 and the free end of the hook and loop tape 300 to move along the first horizontal direction, and the unwinding device 230 continuously unwinds.

[0036] In this embodiment, the clamping mechanism 120 includes a limiting component and a front end pressure plate 121. The limiting component is used to limit the hook and loop fastener strip 300. The front end pressure plate 121 is connected to the limiting component and is disposed opposite to the support base plate 110, and is used to clamp the opposite sides of the hook and loop fastener strip 300 in the thickness direction together with the support base plate 110.

[0037] Specifically, the limiting assembly includes a main support 124 and a side limiting member 125. The side limiting member 125 extends in a first horizontal direction, and one end of the side limiting member 125 is connected to the main support 124. The main support 124 has a limiting arm 1241 parallel to the side limiting member 125. The limiting arm 1241 and the side limiting member 125 are spaced apart in a second horizontal direction, forming a material strip limiting groove 123 between them.

[0038] The tape limiting groove 123 extends along a first horizontal direction, and one end of it has an opening 1231 for the free end of the hook and loop tape 300 to enter. The front end pressure plate 121 is disposed at the opening 1231 and connected to the limiting arm 1241. When the free end of the hook and loop tape 300 enters the tape limiting groove 123 through the opening 1231, the limiting arm 1241 and the side limiting member 125 are respectively opposite to the two sides of the hook and loop tape 300 in the width direction, thereby limiting the two sides of the hook and loop tape 300 in the width direction.

[0039] In fact, in the first horizontal direction, the opening 1231 of the strip limiting groove 123 is opposite to the unwinding device 230. The free end of the hook and loop tape 300, after being unwound by the unwinding device 230, passes through the gap between the front end pressure plate 121 and the supporting base plate 110 and then extends into the strip limiting groove 123 through the opening 1231. In this state, the strip limiting groove 123 limits the relative sides of the hook and loop tape 300 in the width direction, and the front end pressure plate 121 has a certain elastic recovery performance, pressing the hook and loop tape 300 onto the supporting base plate 110.

[0040] In another embodiment, the front end pressure plate 121 can also be connected to the side limiting member 125, or simultaneously connected to both the side limiting member 125 and the limiting arm 1241.

[0041] In this embodiment, a pressure block 241 is provided on the sewing device 240, which is configured to press the hook and loop fastener tape 300 under the drive of the sewing device 240. In practical applications, after the front pressure plate 121 presses the hook and loop fastener tape 300 onto the supporting base plate 110, the driving device 220 drives the supporting base plate 110 to move along the first horizontal direction. The supporting base plate 110 and the front pressure plate 121 clamp and pull the free end of the hook and loop fastener to move a certain distance along the first horizontal direction. At this time, the sewing device 240 is above the supporting base plate 110, and in the first horizontal direction, the sewing device 240 is located between the front pressure plate 121 and the unwinding device 230.

[0042] In this state, the sewing device 240 drives the pressure block 241 to press the portion of the hook and loop fastener 300 behind the front pressure plate 121 onto the support base plate 110. Then, the drive device 220 drives the support base plate 110 to move in the opposite direction to the first horizontal direction, i.e., towards the unwinding device 230. The frictional force between the pressure block 241 and the hook and loop fastener 300 is greater than the frictional force between the front pressure plate 121 and the hook and loop fastener 300, causing the hook and loop fastener 300 to slide relative to the front pressure plate 121, and the free end of the hook and loop fastener 300 gradually extends into the tape limiting groove 123.

[0043] In order to ensure that the Velcro strip 300 slides smoothly relative to the front end pressure plate 121 and avoid jamming, in this embodiment, both ends of the front end pressure plate 121 are folded upward to form a smooth guide portion 1211.

[0044] In order to limit the length of the Velcro tape 300 extending into the tape limiting groove 123 to meet the sewing size requirements, in this embodiment, the limiting component also includes an end limiting member 126 connected to the limiting arm 1241. The end limiting member 126 extends at least partially into the tape limiting groove 123 and is disposed opposite to the opening 1231. The end limiting member 126 is used to stop and limit the end wall of the free end of the Velcro tape 300.

[0045] In another embodiment, the end limiting member 126 may be connected to the side limiting member 125, or simultaneously connected to both the side limiting member 125 and the limiting arm 1241.

[0046] Understandably, as the drive unit 220 drives the supporting base plate 110 to move towards the unwinding device 230, the free end of the hook and loop tape 300 gradually extends into the tape limiting groove 123 and gradually approaches the end limiting member 126. When the broken wall of the free end of the hook and loop tape 300 contacts the end limiting member 126, the length of the hook and loop tape 300 extending into the tape limiting groove 123 meets the dimensional requirements.

[0047] In order to accommodate Velcro strips 300 of different widths, in this embodiment, the main support 124 also has a plurality of first mounting portions 1244 arranged sequentially at intervals along a second horizontal direction. The side limiting member 125 is detachably connected to a portion of the plurality of first mounting portions 1244. The second horizontal direction is the width direction of the strip limiting groove 123.

[0048] In practical applications, the distance between the side limiting member 125 and the limiting arm 1241 in the second horizontal direction can be adjusted according to the different width dimensions of the Velcro tape 300, and the side limiting member 125 can be connected to the first mounting part 1244 at the corresponding position on the main body bracket 124.

[0049] Similarly, in order to adapt to different sewing length requirements, in this embodiment, the limiting arm 1241 has a plurality of second mounting portions 1245 arranged sequentially at intervals along the first horizontal direction, and some of the plurality of second mounting portions 1245 are detachably connected to the end limiting member 126.

[0050] In practical applications, depending on different sewing size requirements, the distance between the end limiting member 126 and the opening 1231 of the tape limiting groove 123 in the first horizontal direction is adjusted, and the end limiting member 126 is connected to the second mounting part 1245 at the corresponding position on the limiting arm 1241. This ensures that when the end wall of the free end of the hook and loop fastener contacts the end limiting member 126, the length of the hook and loop fastener tape 300 extending into the tape limiting groove 123 meets the required size.

[0051] After the end wall of the free end of the hook and loop fastener 300 contacts the end limiting member 126, the sewing device 240 drives the pressure block 241 to move upward, releasing the pressure on the hook and loop fastener 300. Then, the drive device 220 drives the supporting base plate 110 to move in the first and second horizontal directions, so that the laser cutting device 250, located above the work platform 210, completes the cutting of the portion of the hook and loop fastener 300 that extends into the tape limiting groove 123.

[0052] In order to allow space for the laser cutting process, in this embodiment, the side limiting member 125 is provided with a first clearance notch 1252 on the side near the limiting arm 1241, and the limiting arm 1241 is provided with a second clearance notch 1243 on the side near the side limiting member 125. The first clearance notch 1252 and the second clearance notch 1243 are arranged opposite to each other in the second horizontal direction.

[0053] Furthermore, a first folded edge 1251 is provided at the bottom of the side limiting member 125 near the limiting arm 1241, and a second folded edge 1242 is provided at the bottom of the side limiting member 125 near the limiting arm 1241. Both the first folded edge 1251 and the second folded edge 1242 extend into the material strip limiting groove 123 to jointly support the Velcro material strip 300.

[0054] It is understandable that after the laser cutting device 250 completes the cutting of the Velcro tape 300, the two sides of the cut portion in the width direction are respectively on the first fold 1251 and the second fold 1242, that is, the first fold 1251 and the second fold 1242 together support the cut portion.

[0055] In this embodiment, the clamping mechanism 120 further includes a first driving member 122, which is disposed on the bearing base plate 110 and connected to the limiting component, for driving the limiting component to move in the vertical direction to approach or move away from the bearing base plate 110.

[0056] Specifically, the first driving member 122 is connected to the main support 124. After the laser cutting device 250 completes the cutting of the hook and loop tape 300, the first driving member 122 drives the main support 124 to move the side limiting member 125, the front pressing plate 121, and the cut portion of the hook and loop tape 300 upwards together, creating a gap between the main support 124 and the supporting base plate 110. Then, the object to be sewn is placed in the area corresponding to this gap on the supporting base plate 110, and the first driving member 122 again drives the main support 124 to move the side limiting member 125, the front pressing plate 121, and the cut portion of the hook and loop tape 300 downwards together until the main support 124 presses down on the object to be sewn. At this time, the cut portion of the hook and loop tape 300 is on the surface of the object to be sewn.

[0057] In this embodiment, the hook and loop fastener 100 further includes a positioning mechanism 130, which is disposed on the supporting base plate 110 and is used to press the cut portion of the hook and loop tape 300 onto the object to be sewn after the free end of the tape is cut. Specifically, the positioning mechanism 130 includes a second driving member 131 and a pressing member 132. The second driving member 131 is disposed on the supporting base plate 110 and connected to the pressing member 132, and is used to drive the pressing member 132 to move in a vertical plane to selectively press the cut portion of the hook and loop tape 300.

[0058] Understandably, after the first driving member 122 drives the main support 124 to press the object to be sewn, the second driving member 131 drives the pressing member 132 to move until the pressing member 132 presses the cut part of the Velcro tape 300 onto the surface of the object to be sewn, and then the sewing device 240 sews the cut part to the object to be sewn.

[0059] It should be noted that the main support 124 in this embodiment is U-shaped and has two limiting arms 1241 extending along the first horizontal direction. The number of side limiting members 125 is also two, which are respectively arranged corresponding to the two limiting arms 1241 to form two material strip limiting grooves 123.

[0060] In practical applications, the two tape limiting grooves 123 can respectively accommodate two hook and loop fastener tapes 300, allowing two hook and loop fasteners to be sewn onto the object to be sewn simultaneously. Furthermore, the two hook and loop fastener tapes 300 can have their burr sides opposite, i.e., the burr side of one hook and loop fastener tape 300 faces upwards, and the burr side of the other hook and loop fastener tape 300 faces upwards, thus enabling simultaneous burr and burr sewing on the object to be sewn.

[0061] It is understood that in this embodiment, there are two front-end pressing plates 121 and two end limiting members 126. In another embodiment, the number of limiting arms 1241 and side limiting members 125 can be adjusted according to actual application conditions to form other numbers of material strip limiting grooves 123, and the corresponding number of front-end pressing plates 121 and end limiting members 126 can be configured.

[0062] In summary, the hook and loop fastener 100 provided in this embodiment can be applied to the hook and loop sewing equipment 200, enabling the hook and loop sewing equipment 200 to automatically feed the hook and loop tape 300, avoiding the need for an external feeding device. Benefiting from the beneficial effects of the hook and loop fastener 100, the hook and loop sewing equipment 200 provided in this embodiment has the characteristics of simple structure, easy collaborative control, and lower production cost.

[0063] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
