[0017] The present invention will be further described below in conjunction with the accompanying drawings: like Figure 1 and Figure 2As shown, this embodiment provides a high-efficiency non-woven bag forming machine, including a handle winding and carrying system 1, a handle winding system 2, a clamping and fixing system 3, a bisection system 4, a traction system 5 and two cutting systems 6, the clamping and fixing system 3 has a clamping position, the handle winding and carrying system 1 includes two protruding conveying devices 11, the two protruding conveying devices 11 are located on both sides of the clamping and fixing system 3, and the two protruding conveying devices 11 are each provided with a plurality of winding reference columns 111, the handle winding system 2 has a traction end perpendicular to the movement direction of the protruding conveying device 11, and the movement trajectory of the traction end extends to the outside of each winding reference column 111, and the traction end is penetrated by a handle belt 7, and the handle belt 7 is pulled to the outside of each winding reference column 111 under the traction of the traction end, and then each winding reference column 111 is conveyed to the clamping position under the conveyance of the protruding conveying device 11. Towards the conveyor, the clamping and fixing system 3 conveys two clamping belts 8 and clamps the handle belt 7 at the clamping position. The clamping belt 8 has been pre-coated with glue. Applying glue on the clamping belt 8 belongs to the existing technology and will not be repeated here. In this way, the two clamping belts 8 clamp the handle belt 7 and bond it into a whole. The clamping position is at the same height as the movement trajectory of each winding reference column 111. The traction system 5 is installed on the side of the clamping position away from the handle winding and loading system 1, and then the two clamping belts 8 clamping the handle belt 7 are pulled out. The cutting system 4 is installed between the traction system 5 and the clamping position, and then each clamping belt 8 and the handle belt 7 are cut into two strips. Each cutting system 6 is installed on the side of the traction system 5 away from the cutting system 4. The cutting system 6 cuts the clamping belt 8 into sections, and then the handle belt 7 and the clamping belt 8 divided into sections form sections of handles with reinforced parts.

[0018] Specifically, each raised conveying device 11 includes a raised conveying belt 112 and a plurality of winding reference columns 111. Each winding reference column 111 is installed on the raised conveying belt 112. The two raised conveying devices 11 follow the raised conveying belt 112 and move at a constant speed. Each winding reference column 111 constrains the direction of the handle belt 7 so that the handle belt 7 forms a handle shape. It is worth noting that in order to prevent the handle belt 7 from accidentally falling off the winding reference column 111, an annular groove is provided on the winding reference column 111. However, in order to ensure that the winding reference column 111 can be smoothly separated from the handle belt 7 under the drive of the raised conveying belt 112, the depth of the annular groove is 1 mm to 2 mm.

[0019] Specifically, the handle winding system 2 includes a reciprocating traction device 21, an elastic device 22 and a rotating guide device 23. The elastic device 22 is installed at the output end of the reciprocating traction device 21. The reciprocating traction device 21 is a linear guide device. The linear guide device is a prior art and will not be described in detail herein. The reciprocating traction device 21 pulls the elastic device 22 to reciprocate. The elastic device 22 is used to avoid each winding reference column 111 to prevent collision. The rotating guide device 23 is rotatably installed at the bottom of the elastic device 22. The rotating guide device 23 has a traction hole 2321, and the traction hole 2321 forms a traction end. The traction hole 2321 can rotate, so that the rotating guide device 23 follows the reciprocating traction. The device 21 can adapt to the direction of the handle belt 7 when it reciprocates. Specifically, the elastic device 22 is a rubber rod, and the rotating guide device 23 includes a rotating bearing 231 and a rotating rod 232. The rotating rod 232 is installed on the lower side of the elastic device 22 through the rotating bearing 231. The traction hole 2321 is located on the rotating rod 232, and the handle belt 7 passes through the traction hole 2321. In this way, when the elastic device 22 is reciprocated along the reciprocating traction device 21, the rubber rod will be offset due to the squeezing of the winding reference column 111, so that the rotating rod 232 slides along the outer contour of the winding reference column 111, avoiding rigid collision while ensuring that the handle belt 7 is reliably wound on the winding reference column 111.

[0020] Specifically, the clamping and fixing system 3 includes an upper pressure roller 31 and a supporting plate 32. The upper pressure roller 31 rotates above the supporting plate 32. The lower end of the upper pressure roller 31 is located above the plane where the movement trajectory of each winding reference column 111 is located. The supporting plate 32 is located below the plane where the movement trajectory of each winding reference column 111 is located. A clamping position is formed between the upper pressure roller 31 and the supporting plate 32. The upper pressure roller 31 and the supporting plate 32 are used to drive the two clamping belts 8 and then clamp the handle belt 7.

[0021] Specifically, the bisection system 4 is rotatably mounted on the upper side of the support plate 32 to cut each clamping strap 8 and handle strap 7 into two strips.

[0022] Specifically, the traction system 5 includes a pair of traction rollers arranged on the upper and lower sides of the plane where the winding reference column 111 is located, and then pulls out the two clamping belts 8 clamping the handle belts 7.

[0023] Specifically, each cutting system 6 includes two upper cutting knives and a lower cutting knives arranged opposite to each other to cut the clamping belt 8 into sections, thereby forming sections of handles with reinforced parts.

[0024] The bag forming process includes the following steps: S1: The traction end is provided with a handle belt 7 and drives the handle belt 7 to be wound around the winding reference column 111 in sequence; S2: The winding reference column 111 moves to send the wound handle belt 7 into the clamping position; S3: The clamping and fixing system 3 drives the two clamping belts 8 to clamp the handle belt 7 at the clamping position; S4: The cutting system 4 cuts in half and pulls out under the traction of the traction system 5; S5: The cutting system 6 cuts off the two clamping belts 8 clamping the handle belt 7 and then sticks them to the bag body.
