It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0025] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0026] Embodiment 1:

[0027] Combination Figure 1-5 As shown, this embodiment provides a high-efficiency punching device for a stretch-resistant OPP woven bag, including: a main body module 100 and a punching module 200 .

[0028] Among them, the main module 100 includes a base 110, a bottom plate 120 fixed to the top of the base 110, a lower rubber pad 130 fixed to the top of the bottom plate 120, a bracket 140 fixed to both sides of the base 110, a first electric telescopic rod 150 installed on the bracket 140, a support plate 160 fixed to the end of the first electric telescopic rod 150, a column 170 fixed to the top of the support plate 160, and an upper rubber pad 180 fixed to the bottom of the support plate 160.

[0029] The base 110 is used to install other components and ensure the stability of each component. The bottom plate 120 is fixed to the top of the base 110, and the lower rubber pad 130 is fixed to the top of the bottom plate 120 to increase the friction between the bottom plate 120 and the woven bag.

[0030] The bracket 140 is used to install the first electric telescopic rod 150, and the first electric telescopic rod 150 is used to install the support plate 160 and drive the support plate 160 to move up and down, so as to cooperate with the bottom plate 120 to press the woven bag and keep the woven bag stable during punching. A plurality of hemispherical protrusions 131 are provided on the top end surface of the lower rubber pad 130, and a plurality of hemispherical grooves 181 are provided on the bottom end surface of the upper rubber pad 180. The two are interlocked with each other, which can increase the contact area with the woven bag, further increase the friction between the lower rubber pad 130, the upper rubber pad 180 and the woven bag, and ensure the stability of the woven bag.

[0031] The column 170 is used to install the punching module 200 to ensure the stability of the punching module 200.

[0032] The punching module 200 is used to perform punching operations on woven bags, including a turntable 210 rotatably sleeved on the column 170, a plurality of punching members 220 installed in a ring array in the turntable 210, a second electric telescopic rod 230 installed on the column 170, a gear ring 240 fixedly sleeved on the outer surface of the turntable 210, and a driving member 250 installed on one side of the support plate 160 and meshing with the gear ring 240.

[0033] The turntable 210 is rotatably sleeved on the column 170, so that the punching member 220 of different diameters can be switched by rotation. A plurality of circular holes are opened in a circular array on the turntable 210, and an annular groove 211 is opened on the inner wall of each circular hole. The punching member 220 includes a circular plate 221 embedded in the annular groove 211, a punch 222 fixed to the bottom end of the circular plate 221, and a spring 223 fixed to the inner bottom wall of the annular groove 211 at one end and the bottom end of the circular plate 221 at the other end. The diameter of the punch 222 in each circular hole gradually decreases in a clockwise direction, and the diameter of the circular plate 221 is equal to the diameter of the annular groove 211, so that the circular plate 221 can move in the annular groove 211 while being limited by the annular groove 211 on the circular plate 221. The punch 222 is used to punch holes in the woven bag, and the spring 223 is used to drive the bottom plate 120 to reset, and the reset of the punch 222 is driven by the reset of the bottom plate 120.

[0034] In addition, a through hole 161 is formed on the support plate 160 for the punch 222 to pass through and punch holes in the woven bag. Meanwhile, the through hole 161, the second electric telescopic rod 230 and a circular hole on one side of the turntable 210 are located on the same vertical line.

[0035] The driving member 250 is used to drive the turntable 210 to rotate, and includes a side plate 251 fixed to one side of the support plate 160, a motor 252 installed at the bottom end of the side plate 251 and with the shaft extending out of the side plate 251, and a gear 253 fixed on the shaft of the motor 252. The gear 253 and the gear ring 240 are meshed with each other, so that when the motor 252 drives the gear 253 to rotate, the gear 253 rotates to drive the gear ring 240 to rotate, and the gear ring 240 rotates to drive the turntable 210 to rotate.

[0036] The working principle and use process of the utility model are as follows: when in use, the woven bag is placed on the lower rubber pad 130, the size of the holes to be punched is determined, and the motor 252 is started. The rotation of the motor 252 drives the gear 253 to rotate, the rotation of the gear 253 drives the gear ring 240 to rotate, the rotation of the gear ring 240 drives the turntable 210 to rotate, the rotation of the turntable 210 drives the punching piece 220 to rotate, and the punching piece 220 that meets the punching requirements is rotated to the bottom of the second electric telescopic rod 230. At this time, the first electric telescopic rod 150 is started, driving the support plate 160 to press down, and the support plate 160 is pressed down so that the upper rubber pad 180 presses the woven bag against the surface of the lower rubber pad 130 to maintain the stability of the woven bag when punching. Then the second electric telescopic rod 230 is started, driving the punching piece 220 to move downward, passing through the through hole 161 on the support plate 160, and punching the woven bag.

[0037] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
