Description

Technical Field

[0001] This application relates to the field of kraft paper bags, and particularly to a kraft paper bag hole-cutting device. Background Art

[0002] Kraft paper bags are non-toxic, odorless, and pollution-free. They are a type of high-strength and highly environmentally friendly packaging bag. Therefore, many foods sold on the market now choose kraft paper bags as packaging bags. However, since kraft paper bags are paper bags and are opaque, it is difficult for consumers to directly see the appearance of the food inside the kraft paper bag, which makes it difficult for consumers to judge the quality of the food, thereby reducing consumers' desire to purchase.

[0003] In the production and processing process of kraft paper bags, the hole-cutting operation is a common and crucial link. The accuracy of current hole-cutting devices is difficult to guarantee, resulting in a large deviation in the hole positions of the paper bags, failing to meet the expected usage standards. At the same time, the cut edges are often uneven, greatly affecting the appearance quality and functional integrity of the paper bags. The existence of these problems seriously restricts the production and processing efficiency and quality of kraft paper bags. Therefore, it is necessary to provide a kraft paper bag hole-cutting device to solve the above technical problems. Summary of the Utility Model

[0004] The purpose of the present utility model is to provide a kraft paper bag hole-cutting device to solve the problems raised in the above background art.

[0005] The embodiments of this application adopt the following technical solutions:

[0006] A kraft paper bag hole-cutting device includes a base. The upper surface of the base is fixedly connected with a support platform. The upper surface of the support platform is fixedly connected with a protective frame. The upper surface of the protective frame is fixedly connected with a mounting seat. The inner wall of the mounting seat is fixedly connected with a first electric hydraulic telescopic rod. The bottom surface of the first electric hydraulic telescopic rod is fixedly inlaid with a motor. The output end of the motor is fixedly connected with a quick-release sleeve. The inner wall of the quick-release sleeve is clamped with a drilling sleeve. The inner bottom wall of the protective frame is provided with a drilling area. The back surface of the protective frame is fixedly connected with a fixed seat. The inner wall of the fixed seat is fixedly connected with a second electric hydraulic telescopic rod. The front surface of the second electric hydraulic telescopic rod is fixedly connected with a push plate. Two driving rollers are clamped inside the protective frame. A transmission belt is sleeved on the outer surfaces of the two driving rollers. Two third electric hydraulic telescopic rods are clamped inside the protective frame. The inner side surfaces of the two third electric hydraulic telescopic rods close to each other are fixedly connected with limiting frames.

[0007] Preferably, the bottom surface of the base is fixedly connected with two support legs, and the bottom surface of each support leg is fixedly connected with a support foot.

[0008] Preferably, an anti-slip pad is fixedly connected to the bottom surface of each of the support feet, and the anti-slip pad is made of rubber.

[0009] Preferably, a touch panel is fixedly connected to the front surface of the support platform, a potential seat is fixedly connected to the front surface of the support platform, and an alarm lamp is fixedly connected to the front surface of the potential seat.

[0010] Preferably, a sign is provided on the left side of the support platform, and the right side surface of the sign is fixedly connected to the left side surface of the support platform.

[0011] Preferably, two protective doors are snap-connected to the front surface of the protective frame, an observation window is opened on the front surface of each of the protective doors, and a buckle groove is opened on the front surface of each of the protective doors.

[0012] Preferably, two limiting sliding grooves are opened on the inner bottom wall of the protective frame, a limiting sliding block is slidably connected to the inner wall of each of the limiting sliding grooves, and the upper surface of each of the limiting sliding blocks is fixedly connected to the bottom surface of the limiting frame.

[0013] The above at least one technical solution adopted in the embodiments of the present application can achieve the following beneficial effects:

[0014] First, set the working parameters of the device through the touch panel, then open the protective door, and place the kraft paper bag to be cut holes flatly at the starting position of the conveyor belt. When the paper bag approaches the drilling area, the second electro-hydraulic telescopic rod is automatically started, and it is pushed into the drilling area in cooperation with the push plate. Subsequently, start the two third electro-hydraulic telescopic rods, and make them slowly extend to push the limiting frames closer to each other to limit the paper bag in the left and right directions, which can ensure the accurate position of the paper bag in the drilling area, thereby improving the accuracy and consistency of the hole cutting. At the same time, the automated pushing and limiting operations reduce the possible position deviation caused by manual operation and improve the quality stability of the product.

[0015] Second, set the descending speed and stroke of the first electro-hydraulic telescopic rod through the touch panel, drive the motor, quick-release sleeve and drilling sleeve to descend uniformly. At the same time, start the motor to drive the drilling sleeve to rotate and cut holes in the paper bag. The descending depth of the drilling sleeve can be accurately controlled, so as to ensure that the depth of the cut hole meets the requirements. And the uniform descent combined with the motor driving the drilling sleeve to rotate can make the hole cutting process smoother, reduce the unevenness and burrs of the cut, and improve the accuracy and smoothness of the hole cutting.
