[0032] In order to make the above-mentioned purposes, features and advantages of the present application more apparent, obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0033] With reference to Figures 1-4 The present application provides an edge cutting device for non-woven fabric bag production, which comprises a machine table 1 for conveying non-woven fabric material 2 along the axial direction, and further comprises:

[0034] A cutter 9 mechanism is arranged on the machine table 1, and the cutter 9 mechanism can define a slitting interval on the top surface of the machine table 1, and the width of the slitting interval is adjustable.

[0035] A pair of positioning plates 3 are connected to the two sides of the top surface of the machine table 1 in a sliding manner, and are arranged at the rear end of the cutter 9 mechanism along the axial direction of the machine table 1. A control member is arranged on the machine table 1, and the control end of the control member is connected to the pair of positioning plates 3 respectively, so that the pair of positioning plates 3 can move closer to or away from each other. The spacing of the pair of positioning plates 3 corresponds to and matches the width of the non-woven fabric material 2.

[0036] A pair of push plates 4 are arranged at the rear end of the positioning plates 3, and the pair of push plates 4 are respectively fixed to the two sides of the top surface of the machine table 1 along the width direction, and the spacing of the pair of push plates 4 is greater than the width of the non-woven fabric material 2. The mutually far apart sides of the pair of push plates 4 are used for sliding contact with the edge waste 22.

[0037] The present application utilizes the cutter 9 mechanism to slit the non-woven fabric material 2, so as to form non-woven fabric products 21 and edge waste 22 respectively. The spacing between the pair of positioning plates 3 can match the width of the non-woven fabric material 2, and the positioning plates 3 are arranged at the rear end of the cutter 9 mechanism. The non-woven fabric products 21 and the edge waste 22 can be folded together by the cooperation of the pair of positioning plates 3. The pair of push plates 4 arranged at the rear end of the positioning plates 3 utilize the mutually far apart sides of the push plates 4 to slide with the edge waste 22, so that the non-woven fabric material 2 can effectively separate from the non-woven fabric products 21 when moving along the direction from the positioning plates 3 to the push plates 4. Due to the positioning effect of the positioning plates 3, the direction of the force acting on the edge waste 22 in the traditional technology, such as gravity or suction force, can be changed by the positioning plates 3, so as to form a pulling force along the axial direction of the machine table 1, thereby effectively reducing the tearing of the connection between the edge waste 22 and the non-woven fabric products 21, and improving the edge cutting effect.

[0038] In the technical solution, the collecting box 5 is placed at the rear end of the machine table 1, the edge waste 22 is inserted into the collecting box 5, and the edge waste 22 is formed in the direction away from the machine table 1 by the action of gravity, so as to promote the separation of the edge waste 22 from the non-woven fabric product 21.

[0039] Further, the control member comprises:

[0040] The bidirectional screw 6 is connected to the machine table 1, the top surface of the machine table 1 is provided with a sliding groove, and a pair of positioning plates 3 are slidably connected to the two sides of the sliding groove and are symmetrically arranged along the center of the bidirectional screw 6. The mutually close sides of the pair of positioning plates 3 are in sliding contact with the edges of the non-woven fabric material 2.

[0041] The knob 7 is connected to one side of the machine table 1, and the axis of the knob 7 is fixedly connected to one end of the bidirectional screw 6.

[0042] The bidirectional screw 6 is rotated by the knob 7, and the distance between the pair of positioning plates 3 is adjusted, so that the folding operation is performed on the non-woven fabric material 2 with different widths, and the positioning plates 3 are in contact with the edges of the non-woven fabric material 2.

[0043] Further, the positioning plate 3 and the cutter mechanism define a folding interval, and the length of the folding interval is greater than zero.

[0044] The positioning plate 3 forms a guide for the tearing force generated by the edge waste 22, effectively reduces the tearing damage between the edge waste 22 and the non-woven fabric product 21, and affects the edge cutting effect of the non-woven fabric material 2. Through the length of the folding interval being greater than zero, the guiding effect of the edge waste 22 is ensured.

[0045] Further, the width of the slitting interval is less than the width of the non-woven fabric material 2.

[0046] Since the width of the slitting interval can be adjusted, the slitting interval can effectively cut the edges of the non-woven fabric material 2, so as to ensure the formation of the non-woven fabric product 21 and the edge waste 22.

[0047] Further, the cutter mechanism comprises:

[0048] The gantry 8 is fixedly connected to the top surface of the machine table 1 along the width direction of the machine table 1.

The driving end of the driving assembly is connected to the cutters 9, so that the pair of cutters 9 are close to or away from each other and are rotatably connected to the gantry 8. The pair of cutters 9 form a slitting interval therebetween.

[0050] By setting a pair of cutters 9 in the gantry 8 oppositely, and by driving the cutters 9 through the driving assembly, the cutters 9 can rotate for edge cutting while also approaching or moving away from each other, thereby forming an adjustable width of the slitting interval.

[0051] Further, the driving assembly comprises:

[0052] A mounting plate 13 is arranged on the gantry 8 and configured to be lifted relative to the top surface of the machine table 1;

[0054] By using the first hydraulic cylinder 11 and the connecting plate 14 corresponding to the cutter 9, the two connecting plates 14 are driven to approach or move away from each other by the first hydraulic cylinder 11, thereby adjusting the width of the slitting interval, and the driving motor 10 fixedly connected on the connecting plate 14 drives the cutter 9 to rotate to act on the non-woven fabric material 2 for edge cutting.

[0055] Further, it further comprises:

[0056] A second hydraulic cylinder 12 is fixedly connected on the gantry 8, and the piston end of the second hydraulic cylinder 12 extends vertically downward and is fixedly connected with the mounting plate 13.

[0059] By using the mounting plate 13 and the guide grooves of the gantry 8 for limitingly and slidably connecting, the lifting stability of the mounting plate 13 is improved.

[0060] The working principle of the edge cutting device for non-woven fabric bag production is:

[0061] Taking the production of non-woven fabric bag as an example, the non-woven fabric material 2 is unwound along one side of the machine 1 through an unwinding roller (not shown in the figure), when the non-woven fabric material 2 passes under the cutter 9, the second hydraulic cylinder 12 drives the mounting plate 13 to descend, so that the cutter 9 contacts with the non-woven fabric material 2, the driving motor 10 rotates the cutter 9 to cut the edge, and the non-woven fabric product 21 and the edge waste 22 are formed respectively, the non-woven fabric product 21 is wound through a winding roller (not shown in the figure), and the edge waste 22 is collected in the collecting box 5, the non-woven fabric product 21 and the edge waste 22 that move out of the gantry 8 are folded through the positioning plate 3, and the non-woven fabric product 21 and the edge waste 22 are separated through the push plate 4 along with the movement of the non-woven fabric product 21, so that the edge cutting effect of the non-woven fabric material 2 is improved.
