[0002] Currently, most clothing items are provided with pockets. When sewing the pocket fabric, a lining is added to the lower side of the main body fabric. The lining is generally processed from a continuous lining cloth by a scissor mechanism, and is adsorbed and conveyed to the workbench by a lining suction assembly to participate in sewing.

[0003] In actual operation, the lining suction assembly needs to adapt to different sizes of linings to complete the processing and conveying of the linings.

[0038] See Figure 1 , Figure 2 In one embodiment of the present application, a suction lining device for a patch pocket machine is provided, including:

[0039] A sewing table board 100, the top surface of which is a working surface, and a lining receiving window 101 is opened on the working surface;

[0040] A lining feeding moving frame 200, on which a first-level lifting seat 201 is installed, and a second-level lifting seat 202 capable of lifting relative to the first-level lifting seat 201 is installed on the first-level lifting seat 201;

[0041] The suction lining working head 300 is installed on the secondary lifting seat 202. The interior of the suction lining working head 300 is a vacuum chamber 302. The top surface of the suction lining working head 300 is provided with suction lining holes 301 communicating with the vacuum chamber 302. The suction lining working head 300 can align with the lining receiving window 101 along with the lining feeding moving frame 200. The suction lining working head 300 has a temporary stay position where the top surface is lower than the working surface, and a working position where the top surface is flush with the working surface (see Figure 1 ).

[0042] In this embodiment, the top surface with the suction lining holes 301 can increase the adsorption area of the suction lining working head 300, thereby improving the adaptability to pads of different sizes. Cooperating with the lining feeding moving frame 200 provided with the primary lifting seat 201 and the secondary lifting seat 202, different staying positions of the suction lining working head 300 can be achieved. It is possible to complete the inspection and throwing of the pad at the temporary stay position, avoid the influence of the throwing action on the working surface and subsequent sewing, reduce the influence of the defects of the pad on continuous operation, and improve work efficiency.

[0043] In one of the embodiments, see Figure 2 , Figure 3 , the lining feeding moving frame 200 includes a support frame 203. A guide rail 204 is fixed to the support frame 203. The primary lifting seat 201 is slidably engaged with the guide rail 204. A first driving mechanism interlocked with the primary lifting seat 201 is installed on the support frame 203. The lining feeding moving frame 200 is interconnected with the sewing table board 100 through the support frame 203, and the sewing table board 100 is connected to the frame of the patch pocket machine. In the figure, the first driving mechanism is a first air cylinder 205. The cylinder body of the first air cylinder 205 is fixed to the support frame 203, and the piston rod is fixed to the primary lifting seat 201. The secondary lifting seat 202 is slidably engaged with the guide rail 204. A second driving mechanism interlocked with the secondary lifting seat 202 is installed on the primary lifting seat 201. In the figure, the second driving mechanism is a second air cylinder 206. The cylinder body of the second air cylinder 206 is fixed to the primary lifting seat 201, and the piston rod is fixed to the secondary lifting seat 202.

[0044] It can be observed that there are two guide rails 204 in the figure and they are arranged in parallel. The primary lifting seat 201 and the secondary lifting seat 202 are respectively slidably engaged with the two guide rails 204. The primary lifting seat 201 and the secondary lifting seat 202 are overlapped with each other in the direction of the guide rail. To avoid interference, the first air cylinder 205 and the second air cylinder 206 are arranged in a staggered manner. Among them, the second air cylinder 206 is located at the middle position between the two guide rails 204, and the first air cylinder 205 is offset compared with the second air cylinder 206. The lifting stroke of the first air cylinder 205 is greater than the lifting stroke of the second air cylinder 206.

[0045] Through the mutual cooperation of the first driving mechanism and the second driving mechanism, pauses at different positions can be achieved. In one embodiment, when the first-level lifting seat 201 rises to a predetermined height, the top surface of the suction lining working head 300 is at the temporary stay position;

[0046] When the second-level lifting seat 202 rises relative to the first-level lifting seat 201 to a predetermined height, the top surface of the suction lining working head 300 is at the working position.

[0047] See Figure 4 , in one embodiment, a negative pressure pipe 303 communicating with the vacuum chamber 302 is connected to the bottom of the suction lining working head 300. The suction lining working head 300 is one or more. At least two negative pressure pipes 303 are connected to the same suction lining working head 300, and all the negative pressure pipes 303 converge into a vacuum distribution chamber 304, and the vacuum distribution chamber 304 is connected to a negative pressure device through a pipeline. In the figure, there are two suction lining working heads 300, which are respectively installed on both sides of the second-level lifting seat 202 near the guide rail 204. The two suction lining working heads 300 are arranged at intervals. Each suction lining working head 300 is connected to multiple negative pressure pipes 303, and the multiple negative pressure pipes 303 are parallel and away from the suction lining working head 300 in the extending direction of the guide rail 204. Correspondingly, the negative pressure pipes 303 connected to the same suction lining working head 300 are a group of negative pressure pipes 303, and the different groups of negative pressure pipes 303 are also arranged at intervals.

[0048] See Figure 5, in one embodiment, the vacuum chamber 302 is strip-shaped and has a length direction, and all the negative pressure tubes 303 connected to the same suction liner working head 300 are arranged in sequence along the length direction. The top of the suction liner working head 300 is a top plate 305 provided with suction liner holes 301. Below the top plate 305, partition plates 306 are arranged at intervals. The vacuum chamber 302 is located between the top plate 305 and the partition plates 306. The partition plates 306 are provided with communication ports 307 connected to the negative pressure tubes 303. In the figure, the negative pressure tubes 303 are inserted into the communication ports 307. The vacuum chamber 302 can be separated by the partition plates 306, so as to realize the distribution of vacuum. When adsorbing gaskets of different sizes or shapes, good adsorption effects can be ensured and the gas consumption of the negative pressure equipment can be reduced. The distance between the partition plates 306 and the top plate 305 can adjust the vacuum effect of each communication hole. In one embodiment, the ratio range between the distance D1 between the top plate 305 and the partition plates 306 and the distance D2 between adjacent partition plates 306 is 0.05 to 0.2. In the figure, the ratio range is 0.08 to 0.15. The multiple partition plates 306 are actually an integral structure. The suction liner working head 300 includes a top plate 305 provided with suction liner holes 301 and a bottom box 308 cooperating with the top plate 305. The bottom of the bottom box 308 is provided with a plurality of communication ports 307 for inserting the negative pressure tubes 303. Along the length direction, 3 to 8 communication ports 307 are evenly arranged. Each communication port 307 is respectively configured with a negative pressure tube 303, and the partition side walls between the communication holes form the partition plates 306. At the same time, except for the outer peripheral wall, the bottom box 308 retracts relative to the bottom plate to form a gap between the top plate 305 and the partition plates 306, and the gap is evenly arranged. Correspondingly, the partition plates 306 can also achieve the corresponding technical effects by setting on-off valves in the vacuum chamber 302 or the communication holes.

[0049] The working process will be described below in combination with each component:

[0050] Place the large body fabric that needs to sew a gasket below on the sewing table board 100. At this time, the negative pressure equipment corresponding to the suction liner working head 300 does not work, and the suction liner working head 300 does not generate adsorption force.

[0051] The piston rods of the first cylinder 205 and the second cylinder 206 retract downward, and the lining adding device sends the stamping formed lining cloth to the top plate 305 of the suction liner working head 300. At this time, the negative pressure equipment starts to work, and the negative pressure equipment realizes the internal negative pressure of the suction liner working head 300 through the negative pressure tubes 303, so that the lining cloth is adsorbed to the top plate 305 of the suction liner working head 300.

[0052] The piston rod of the first cylinder 205 extends upward to reach the preventive material position. At this time, the top surface of the lining suction working head 300 is at a temporary position lower than the working surface, and the operator or the equipment can inspect the gasket and perform corresponding material throwing operations to avoid the gasket affecting the working surface. After inspecting that the gasket is qualified, the piston rod of the second cylinder 206 extends upward to send the lining cloth to the sewing table 100 for sewing operations.

[0053] In this embodiment, the lining suction working head 300 realizes the adsorption of gaskets of different sizes through the optimization of the internal vacuum chamber structure. There is no need to adjust during code change, and the structure is simple and compact. At the same time, it cooperates with the lining feeding moving frame 200 for secondary feeding to achieve process coordination and improve production efficiency.

[0054] Based on the above, in an embodiment of the present application, a pocket attaching machine with the pocket attaching machine lining suction device in the present application is also provided. Other structures of the pocket attaching machine can be implemented in combination with the prior art.

[0055] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as these combinations of technical features do not conflict, they should be considered as the scope described in this specification. When the technical features in different embodiments are shown in the same drawing, it can be regarded that the drawing also discloses the combination examples of the various embodiments involved at the same time.

[0056] The above-described embodiments only represent several implementation manners of the present application. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
