Description

Technical Field

[0001] This invention relates to the field of hemming devices, and more specifically to a hemming device for bag handles. Background Technology

[0002] Generally, after the bag handles are manufactured, they need to be rolled. This not only improves the appearance but also increases the friction of the handles, making them easier for users to grip. It also absorbs sweat produced from prolonged holding, preventing the handles from being corroded by sweat.

[0003] Existing edge-rolling devices for bag handles have the following drawbacks:

[0004] 1. The existing method of using edge-rolling cards for edge-rolling operations is not only inefficient but also wastes a lot of manpower. In addition, different edge-rolling cards are needed when rolling handles of different sizes, making the edge-rolling operation quite complicated.

[0005] 2. The existing edge-rolling card cannot perform continuous edge-rolling operations. After the edge-rolling of the previous workpiece is completed, the edge-rolling operation needs to be repeated when the edge-rolling of the next workpiece is performed. At the same time, since the edge-rolling is done manually, wrinkles will appear after the edge-rolling is completed, which affects the appearance of the finished product.

[0006] Therefore, it is necessary to invent a rolling edge device for bag handles. Summary of the Invention

[0007] To address this, the present invention provides a hemming device for bag handles. By using a positioning mechanism to adjust the spacing between two sets of side plates, it can accommodate workpieces of different specifications. At the same time, by using a clamping component, the hemming fabric is laid all over the side plates, eliminating the need for manual fabric application and facilitating hemming. The fabric pulling component completes the hemming of the workpiece, thus solving the problems of low working efficiency, inability to work continuously, and inability to hem multiple workpieces of different specifications in existing hemming devices.

[0017] The beneficial effects of this invention are:

[0018] 1. By setting the spacing between the two sets of side plates according to the specifications of the workpiece to be edged, the motor output shaft drives the stud to rotate, so that the positioning clamping seat engages with the stud. Under the limiting and guiding action of the slide rod, the positioning clamping seat moves, causing the two sets of positioning clamping seats to slide along the strip slide plate, thereby causing the slide block fixed to it to slide in the limiting slide groove, and causing the L-shaped socket located inside the insertion slot to slide, so that the side plate fixed to the L-shaped socket moves, thereby achieving the purpose of adjusting the spacing between the two sets of side plates.

[0019] 2. Set the hemmed fabric to be covered into a U-shape and insert it into the two sets of side walls. The top two sides of the U-shaped hemmed fabric enter the inner hemming loop through the rubber clamps. Simultaneously, place the two sides of the hemmed fabric into the two sets of clamping components. At this time, the top clamp and bottom clamp can clamp the hemmed fabric. Under the action of spring three, the slider can be pushed to slide within the slide rail, thus covering the entire side plate with the hemmed fabric. Then, insert the workpiece into the two sets of side plates. Under the restoring force of spring one and spring four, rotating plate one and rotating plate two can clamp the workpiece, allowing the hemmed fabric inside the side plate to be hemmed. When the hemming of the workpiece is completed, the sewing machine body can perform a sewing operation on the moving hemming material in the inner hemming loop. After the hemming of a single workpiece is completed, when hemming other workpieces of different specifications with the same material, simply adjust the motor repeatedly to adjust the distance between the two sets of side plates to hemm workpieces of different specifications.

Detailed Implementation

[0035] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0036] See attached document Figure 1-14 The present invention provides a rolling edge device for bag handles, including a rolling device 100 and a sewing machine workbench 200. The rolling device 100 is located inside and connected to the sewing machine workbench 200. The rolling device 100 includes an adjustment device 140 and further includes a fabric pulling assembly 110 connected to the adjustment device 140.

[0037] The fabric pulling assembly 110 has two sets arranged in a mirror symmetrical manner. The fabric pulling assembly 110 includes a side plate 111. L-shaped sockets 112 are fixedly installed on both sides of the bottom of the side plate 111. A top shaft 113 is fixedly installed in the middle of the outer side wall of the side plate 111. A slide rail 120 is provided on the top of the side plate 111. A spring 121 is fixedly installed on the inner left side wall of the slide rail 120. A clamping member 130 is provided inside the slide rail 120.

[0038] Both sets of side plates 111 are provided with arc-shaped baffles 122 on their outer sides. Limit buckles 123 are fixedly installed on both sides of the bottom of the arc-shaped baffles 122. The limit buckles 123 are used in conjunction with the top shaft 113 and the arc-shaped baffles 122 are rotatably connected to the side plates 111. Rubber pads 124 are fixedly installed on the top side wall of the arc-shaped baffles 122. The two sets of rubber pads 124 are used in conjunction to effectively clamp the rolled edge fabric located inside the arc-shaped baffles 122, which is convenient for edge binding of the workpiece. The top side wall of the outer arc-shaped baffles 122 is fixedly installed with rolled edge inner buckles 125. When the U-shaped rolled edge fabric is placed inside the two sets of arc-shaped baffles 122, the top two sides of the rolled edge fabric are pulled into the rolled edge inner buckles 125. After being rolled up inside the rolled edge inner buckles 125, the sewing machine body sews. The rolled edge inner buckles 125 are located on the top of the rubber pads 124 and are seamlessly connected to the rubber pads 124.

[0039] The side plate 111 has a base plate 114 on each of its two outer walls at the top. Each base plate 114 has four sets of pins 115, all of which are fixedly inserted through the base plate 114. The ends of the four sets of pins 115 are fixedly connected to the side wall of the side plate 111, and the base plate 114 is fixedly connected to the side plate 111. The pins 115 serve to fix the side plate 111 and the base plate 114. A rotating plate 116 is rotatably connected to the outside of the base plate 114. A rotating roller 117 is rotatably connected to the outside of the rotating plate 116. The inner walls of both sides at the top of the side plate 111 have buckles 119. The buckle 119 is fixedly connected to the side plate 111 and is located on the same plane as the middle of the rotating plate 116. A spring 118 is fixedly installed on the buckle 119. The spring 118 is always in a stretched state, so as to clamp the workpiece that enters the two sets of side plates 111. The other end of the spring 118 is fixedly connected to the middle of the rotating plate 116. Specifically, by setting the rolled edge cloth to be covered into a U-shape and then inserting it into the two sets of side walls, the top two sides of the U-shaped rolled edge cloth enter the rolled edge inner buckle 125 through the rubber clamping pads 124. Then, the U-shaped rolled edge cloth is covered with the entire interior of the side plate 111 by the two sets of clamping members 130.

[0040] Furthermore, the clamping member 130 includes a slider 131, which works in conjunction with the slide rail 120 and is slidably connected to the top of the side plate 111. The slide rail 120 provides support and guidance. The right end of the second spring 121 is fixedly connected to the left side of the slider 131. In the initial state, the second spring 121 is in a compressed state. At this time, the second spring 121 can push the slider 131 to slide within the slide rail 120 due to its restoring deformation. A bottom clamping seat 132 is fixedly installed on the top of the slider 131, and the slider 131 provides support for the bottom clamping seat 132. A top clamping block 133 is rotatably connected to the side of the bottom clamping seat 132 near the slider 131. The outer wall of the top clamping block 133 fits against the inner wall of the bottom clamping seat 132. A spring 134 is fixedly installed at the bottom of the bottom clamping seat 132. The other end of the spring 134 is fixedly connected to the inner wall of the top clamping block 133 and the spring 134 is always in a stretched state. Under the elastic force of the spring 134, the top clamping block 133 moves into the bottom clamping seat 132, thereby clamping the rolled edge cloth located between the top clamping block 133 and the bottom clamping seat 132. Specifically, the rolled edge cloth is placed in a U-shape on the two sets of arc baffles 122, and the two sides of the rolled edge cloth are placed in the two sets of clamping members 130. At this time, the top clamping block 133 and the bottom clamping seat 132 can clamp the rolled edge cloth. Under the action of the spring 134, the slider 131 can be pushed to slide in the slide rail 120, thereby covering the entire side plate 111 with the rolled edge cloth.

[0041] Furthermore, the adjustment device 140 includes a base 141, on both sides of the middle of the base 141, with inverted protrusions 142 fixedly installed. The base 141 provides support for the inverted protrusions 142. A rotating plate 143 is rotatably connected to the outer top of the inverted protrusion 142. A spring 144 is fixedly installed in the middle of the inner wall of the rotating plate 143. The spring 144 is always in a stretched state. The other end of the spring 144 is fixedly connected to the top of the inverted protrusion 142. A rotating roller 145 is provided on the top of the rotating plate 143 and is rotatably connected to the rotating plate 143. A positioning mechanism 150 is provided on the top of the base 141. Specifically, since the spring 144 is always in a stretched state, the rotating plate 143 keeps moving closer to the inverted protrusion 142, thereby achieving the purpose of pressing the workpiece.

[0042] Furthermore, the alignment mechanism 150 has two sets arranged in a mirror-symmetrical manner. The alignment mechanism 150 includes a bridge-shaped seat 151. The bottom of the bridge-shaped seat 151 is fixedly connected to the base 141, and its sidewall is abutted against the sidewall of the inverted protrusion seat 142. The sidewalls of both sets of bridge-shaped arms of the bridge-shaped seat 151 are provided with sliding grooves 152. The middle of the middle of both sets of bridge-shaped arms of the bridge-shaped seat 151 is provided with limiting sliding grooves 156, and the sliding grooves 152 pass through the limiting sliding grooves 156. A slide seat 153 is provided in the middle of the bridge-shaped seat 151. The two sides of the slide seat 153 are slidably connected to the two sets of limiting sliding grooves 156 respectively. The limiting sliding grooves 156 have a limiting and guiding function, so that the slide seat 153 can only slide along the limiting sliding grooves 156. A strip-shaped sliding plate 154 is fixedly installed at the bottom of the slide seat 153. The strip-shaped sliding plate 154 is used in conjunction with the sliding grooves 152, and the slide seat 153 and the bridge-shaped seat 151 are connected in conjunction with the base 141. 1. Sliding connection: When the strip slide plate 154 slides in the slide groove 152, it can drive the slide seat 153 fixed to it to slide in the limiting slide groove 156. The slide seat 153 has a socket slot 155 on both sides of the top. The two sets of L-shaped sockets 112 are used in conjunction with the two sets of socket slots 155 respectively, and the side plate 111 is slidably connected to the slide seat 153. The strip slide plate 154 has a sliding member 160 on both sides. Specifically, when the positioning clamp 165 drives the strip slide plate 154 to slide, the strip slide plate 154 slides in the slide groove 152, thereby driving the slide seat 153 fixed to it to slide in the limiting slide groove 156, driving the L-shaped socket 112 located inside the socket slot 155 to slide, so that the side plate 111 fixed to the L-shaped socket 112 moves, thereby achieving the purpose of adjusting the distance between the two sets of side plates 111.

[0043] Furthermore, the sliding member 160 includes a receiving seat 161. The bottom of the receiving seat 161 is fixedly connected to the base 141, and its sidewalls are fitted with an inverted protrusion 142. The inverted protrusion 142 can save installation space for the receiving seat 161 and improve the utilization rate of the base 141. A motor 162 is fixedly installed on the outer wall of the receiving seat 161, providing support for the motor 162. Slide rods 163 are fixedly installed on the inner walls of both sides of the receiving seat 161. Studs 164 are rotatably connected to the inner walls of both sides of the receiving seat 161, and the outer sidewall of the stud 164 is fixedly connected to the output shaft of the motor 162. A positioning clamping seat is slidably connected to the outer wall of the slide rod 163. 165. The slide bar 163 has a limiting and guiding function. When the positioning clamp 165 is engaged with the stud 164, the positioning clamp 165 slides only in the direction of the slide bar 163. The positioning clamp 165 is engaged with the stud 164. The outer wall of the positioning clamp 165 is fixedly connected to the end wall of the strip slide plate 154. Specifically, the output shaft of the drive motor 162 drives the stud 164 to rotate, so that the positioning clamp 165 is engaged with the stud 164. Under the limiting and guiding function of the slide bar 163, the positioning clamp 165 moves, thereby causing the two sets of positioning clamps 165 to drive the strip slide plate 154 to slide.

[0044] Furthermore, the sewing machine worktable 200 is provided with an installation groove 210, the covering device 100 is located inside the installation groove 210 and the side wall of the base 141 is fixedly connected to the inner wall of the installation groove 210, the sewing machine worktable 200 provides support for the base 141, the outlet of the hem-rolling inner buckle 125 is on the same horizontal plane as the surface of the sewing machine worktable 200 and the sewing machine body is located on the left side of the hem-rolling inner buckle 125. Specifically, when the hem of the workpiece is completed, the sewing machine body can perform a mending operation on the moving hem material in the hem-rolling inner buckle 125.

[0045] The process of using this invention is as follows: Those skilled in the art can set the distance between the two sets of side plates 111 according to the specifications of the workpiece that needs to be edged. At this time, it is only necessary to drive the motor 162. The output shaft of the motor 162 drives the stud 164 to rotate, so that the positioning clamping seat 165 engages with the stud 164. Under the limiting and guiding action of the slide rod 163, the positioning clamping seat 165 moves, so that the two sets of positioning clamping seats 165 drive the strip slide plate 154 to slide, thereby driving the slide seat 153 fixed to it to slide in the limiting slide groove 156, driving the L-shaped socket 112 located inside the insertion slot 155 to slide, so that the side plate 111 fixed to the L-shaped socket 112 moves, thereby achieving the purpose of adjusting the distance between the two sets of side plates 111.

[0046] The rolled edge fabric to be covered is shaped into a U-shape and then inserted into the two sets of side walls. The top two sides of the U-shaped rolled edge fabric enter the rolled edge buckle 125 through the rubber clamping pads 124. At the same time, the two sides of the rolled edge fabric are placed into the two sets of clamping members 130. At this time, the top clamping block 133 and the bottom clamping seat 132 can clamp the rolled edge fabric. Under the action of the spring 134, the slider 131 can be pushed to slide in the slide rail 120, thereby covering the entire side plate 111 with the rolled edge fabric. Then, the workpiece is inserted into the two sets of side plates 111. Under the restoring force of spring 144, rotating plate 116 and rotating plate 2 143 can clamp the workpiece, so that the hemmed fabric inside the side plate 111 can be hemmed. When the hemming of the workpiece is completed, the sewing machine body can perform a sewing operation on the moving hemming material in the hemming buckle 125. When the hemming of a single workpiece is completed, when hemming other workpieces of different specifications with general-purpose materials, it is only necessary to repeatedly adjust the motor 162 to adjust the distance between the two sets of side plates 111, so that hemming of workpieces of different specifications can be performed.

[0047] The above description is merely a preferred embodiment of the present invention. Any person skilled in the art can modify the present invention or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of the present invention fall within the scope of protection claimed by the present invention.
