[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 An automatic punching mechanism for a nonwoven bag machine includes: a base 1, an infeed assembly 2 disposed on the inner side of the base 1, and a protective assembly 3 disposed on the top of the base 1.

[0025] The feeding assembly 2 includes a sliding groove 21 disposed on the top of the base 1. A feeding rack 22 is slidably disposed on the inner side of the sliding groove 21. An electric telescopic rod 23 is disposed at the bottom of the feeding rack 22. A feeding support plate 24 is slidably disposed on the inner side of the base 1. The top of the feeding support plate 24 is fixedly connected to the bottom of the electric telescopic rod 23.

[0026] When the output end of the electric telescopic rod 23 extends, its top is higher than the base 1, and the non-woven bag is placed inside. With the rotation of the output end of the first motor 26, the rotating screw 25 is driven to rotate, which causes the feeding support plate 24 and the feeding rack 22 to move to the left. During the movement, the feeding rack 22 will move the non-woven bag together. When it moves to the leftmost position, the required opening of the non-woven bag is located directly below the punching punch 37. At this time, the electric telescopic rod 23 can be controlled to retract, which will drive the top of the feeding rack 22 to retract to the inside of the sliding groove 21, thereby controlling the first motor 26 to reset it. When it moves another non-woven bag again, it will push the non-woven bag that has been punched on the front side to move forward and away from the punching structure.

[0027] The protective component 3 includes a support frame 31 disposed on the top of the base 1. A placement box 32 is disposed on the inner side of the support frame 31 and can slide up and down. Guide rods 33 are disposed on the front and back of the placement box 32 and can slide up and down. A protective frame 34 is fixedly disposed at the bottom of the two sets of guide rods 33.

[0028] The protective frame 34 not only reduces the chance of personnel accidentally touching the punch, but also presses down on the non-woven bag during punching to prevent displacement.

[0029] A rotating screw 25 is rotatably mounted on the inner side of the base 1. A threaded sleeve is mounted on the circumferential side of the rotating screw 25, which can move back and forth along its length. The top of the threaded sleeve is fixedly connected to the bottom of the feed support plate 24.

[0030] A first motor 26 is provided on the inner side of the base 1 and at the rear end of the rotating lead screw 25. The output end of the first motor 26 is fixedly connected to the rear end of the rotating lead screw 25.

[0031] When the first motor 26 controls the rotating screw 25 to rotate and the feed rack 22 moves forward, the top of the electric telescopic rod 23 is in the extended state, and vice versa.

[0032] Springs 35 are provided on the periphery of both sets of guide rods 33. The tops of the two sets of springs 35 are respectively fixedly connected to the front and rear sides of the placement box 32. The inner side of the protective frame 34 is provided with a perforated opening, and the bottom of the protective frame 34 is provided with an anti-slip pad.

[0033] The punch opening is designed to allow the punch 37 to pass through, and a spring 35 is provided to press the non-woven bag tightly.

[0034] The inner side of the placement box 32 is provided with two adjusting blocks 36 that can slide left and right. The bottom of each adjusting block 36 is provided with a punch 37. The top of the base 1 and the bottom of the two punches 37 are provided with two auxiliary blocks 38 that can slide left and right.

[0035] The auxiliary block 38 is used to provide an auxiliary hole, and it can move left and right so that the auxiliary hole is directly below the punch 37.

[0036] A bidirectional lead screw 39 is rotatably mounted on the inner side of the placement box 32. The circumferential side of the bidirectional lead screw 39 is threadedly connected to the inner side of two adjusting blocks 36. A second motor 4 is mounted on the inner side of the placement box 32 and at the right end of the bidirectional lead screw 39.

[0037] The rotation of the output end of the second motor 4 drives the rotation of the bidirectional lead screw 39, which in turn drives the two adjusting blocks 36 to move relative to each other or apart, thereby enabling the two punching heads 37 to adjust their positions left and right.

[0038] A punching drive device 5 is provided on the top of the support frame 31. The output end of the punching drive device 5 is fixedly connected to the top of the placement box 32. A main controller 6 is provided on the right side of the base 1. A collection box 7 is provided on the front of the base 1.

[0039] The main controller 6 allocates and controls the various electrical components, and the collection box 7 can collect the perforated non-woven bags that are pushed along.

[0040] The working principle of the automatic punching mechanism for a nonwoven bag machine provided by this utility model is as follows:

[0041] Step 1: When using, first place the non-woven bag in the feed rack 22 on the top rear side of the base 1. The rotation of the output end of the first motor 26 drives the rotation of the rotating screw 25, which in turn drives the feed support plate 24 and the feed rack 22 to move forward. During this process, since the top of the feed rack 22 is attached to the front and rear sides of the non-woven bag, it will also drive the non-woven bag to move forward synchronously. When the feed rack 22 reaches the leftmost side, the hole to be punched on the non-woven bag will be directly below the punching punch 37.

[0042] Step 2: By setting up the punching drive device 5 and the punching punch 37, the punching work of the non-woven bag can be completed. By setting up the guide rod 33, the spring 35 and the protective frame 34, the non-woven bag can be pressed to prevent it from shifting. At the same time, it can also provide a certain protective effect to prevent personnel from contacting the punch part.

[0043] Step 3: During the punching process, the output end of the electric telescopic rod 23 retracts, causing the feed rack 22 to descend a certain distance and lose its pushing effect on the non-woven bag. The reverse rotation of the output end of the first motor 26 drives the rotating screw 25 to rotate, thereby driving the feed support plate 24 and the feed rack 22 to move backward. Then, the output end of the electric telescopic rod 23 extends, causing the feed rack 22 to reset. When a non-woven bag to be punched is placed inside it, the punching of the non-woven bag in front is completed. The output end of the first motor 26 rotates again, driving the feed rack 22 and the non-woven bag to be punched to move forward, so that the punching point of the non-woven bag is below the punching punch 37. At the same time, the punched non-woven bag is squeezed into the collection box 7.

[0044] Compared with related technologies, the automatic punching mechanism for a nonwoven bag machine provided by this utility model has the following advantages:

[0045] By setting up a main controller 6, a first motor 26, a feeding rack 22, and an electric telescopic rod 23, the automatic feeding and discharging of non-woven bags can be realized. The part where the non-woven bags need to be placed or removed is far away from the punching punch 37, thereby reducing the risk of being bumped. At the same time, a protective frame 34 is set up, which can not only avoid bumping again, but also press the non-woven bags before punching to prevent them from shifting, thereby improving punching efficiency and reducing safety hazards.

[0046] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
