Foam has a series of characteristics such as good elasticity, light weight, easy to use, easy to bend, ultra-thin, reliable performance, etc. During the production process, foam is made into different shapes according to the use requirements. During the manufacturing process of an existing foam strip, a punching machine is used to punch out multiple notches on the surface of the foam strip, and at the same time, the foam strip is punched into a fixed length to meet the use requirements of the foam strip.
[0003] In the process of using a punching machine to process foam strips, the foam strips need to be positioned.

In this state, the air delivery channel 22 on the purge frame 19 cannot be aligned and connected with the air source channel 23, so that the blowing nozzle 21 will not blow air.

[0055] Reference Fig.10 When the foam strip cutting process is completed, the top plate 16 rises and passes through the give way groove 13 to lift the foam strip placed on the flexible pad 6. At the same time, the first connecting plate 242 rises synchronously with the top plate 16, gradually releasing the pressure on the lifting block 241 and the second connecting plate 243, so that the purge rack 19 and the second connecting plate 243 move upward under the elastic force of the supporting spring 202, so that the air supply channel 22 on the purge rack 19 moved to a higher position is aligned and connected with the air source channel 23, so that the blowing nozzle 21 can blow air toward the top surface of the flexible pad 6, which helps to blow off the waste generated after the foam strip cutting process, thereby facilitating the next batch of foam strip cutting process.
[0056] Reference Figure 7 A placement groove 32 is provided on the side of the purge rack 19 facing the gas source channel 23, and the placement groove 32 is located just above the position where the gas transmission channel 22 is connected to the second installation groove 17.

When the purge rack 19 moves to a lower position, the placement groove 32 is aligned with the gas source channel 23, so that the sealing plug 34 moves toward the gas source channel 23 under the elastic force of the connecting spring 33, so that the sealing plug 34 blocks the gas source channel 23, thereby helping to prevent the gas in the gas source channel 23 from leaking through the gap between the purge rack 19 and the processing table 2.
[0057] The implementation principle of the embodiment of the present application is as follows: when cutting and processing the foam strips, the operator places a plurality of foam strips on the flexible pad 6, and clamps and positions the foam strips through a plurality of groups of positioning columns 7 arranged in a wave shape, thereby helping to position the foam strips while avoiding deformation of the foam strips as much as possible, helping to improve the positioning effect of the foam strips, thereby improving the accuracy of the processing position of the foam strips, and ensuring the processing precision of the foam strips.
[0058] When the foam strip is positioned, the lifting module 3 drives the punching plate 4 to punch the foam strip, causing the flexible pad 6 to deform, so that the cutting tool 81 can cut the foam strip. At the same time, the cutting tool 82 can cut the foam strip, which helps to ensure the consistency of the length of multiple foam strips.
[0059] When the foam strip is cut, the electromagnetic coil 142 is powered on, and a magnetic field is generated after the electromagnetic coil 142 is powered on, so that the fixed iron core 143 generates magnetism, and then the fixed iron core 143 and the movable iron core 144 attract each other and approach each other, and at the same time, the reset spring 145 is gradually in a contracted state, and the top plate 16 is under the flexible pad 6, which is convenient for cutting the foam strip. At the same time, the first connecting plate 242 presses the lifting block 241, so that the lifting block 241 presses the second connecting plate 243, and then the purge frame 19 presses the top support spring 202, so that the top support spring 202 is in a compressed state. In this state, the air supply channel 22 on the purge frame 19 cannot be aligned and connected with the air source channel 23, and then the blowing nozzle 21 will not blow air.
[0060] When the foam strip cutting process is completed, the operator presses the button switch 15 to cut off the power of the electromagnetic coil 142, so that the fixed iron core 143 is no longer magnetic. At the same time, under the elastic force of the reset spring 145, the reset spring 145 drives the ejector plate 16 and the movable iron core 144 to move upward, so that the ejector plate 16 can automatically lift the foam strip placed on the flexible pad 6, thereby improving the convenience of the operator to take the foam strip after cutting. At the same time, the first connecting plate 242 releases the pressure on the lifting block 241, and the purge rack 19 moves upward under the elastic force of the supporting spring 202, so that the air supply channel 22 on the purge rack 19 moved to a high position is aligned and connected with the air source channel 23, so that the blowing nozzle 21 blows air, which helps to blow off the waste generated after the foam strip cutting process, thereby facilitating the subsequent foam strip cutting process.
[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
