Description

Technical Field

[0001] This utility model belongs to the field of kraft paper bag processing technology, specifically relating to a cutting device for kraft paper bag processing. Background Technology

[0002] Kraft paper bags are bags made of kraft paper. Compared to bags made of other materials, kraft paper bags are more durable and have a certain degree of water resistance and tear resistance, making them widely used in the packaging industry. In the production of kraft paper bags, the edges of the kraft paper need to be cut, which requires the use of cutting equipment.

[0003] Patent application number 202322497502.7 discloses a cutting device for processing kraft paper bags. This invention solves the problem that waste material from existing kraft paper bags cannot automatically fall into the collection box after cutting. This invention uses a support plate, gears, a connecting shaft, and a rack. The fixed plate and the unloading plate are hinged together by the support plate and the connecting shaft. A gear is connected to the outside of the connecting shaft.

[0004] The aforementioned cutting device for processing kraft paper bags uses a cutter to directly cut the kraft paper. Because kraft paper is thicker than ordinary paper, it will move during cutting, causing wrinkles, tears, and unevenness at the edges, thus affecting the quality of the kraft paper bags. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a cutting device for processing kraft paper bags. This cutting device aims to solve the technical problem that, due to the fact that kraft paper is thicker than ordinary paper, it will move during cutting, causing wrinkles, tears, and unevenness at the edges, thus affecting the quality of kraft paper bags.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides a cutting device for processing kraft paper bags. The cutting device includes a cutting platform and a lifting frame disposed above the cutting platform. Kraft paper bag raw material is disposed above the cutting platform. Fastening frames are symmetrically fixed to the side walls of the lifting frame. A connecting plate is elastically disposed between the two fastening frames. A pressure plate for squeezing the kraft paper bag raw material is fixed to the bottom end of the connecting plate. A baffle that is slidably inserted into the cutting platform is fixed to the end of the pressure plate away from the lifting frame.

[0009] When using this technical solution, a cutting blade is fixed at the bottom of the lifting frame, and a pressure plate located below the cutting blade is elastically installed on the side wall of the lifting frame via a fastening frame. When cutting the kraft paper bag material, the kraft paper bag material abuts against the baffle at the bottom of the pressure plate. The hydraulic rod drives the lifting frame to move downwards. The pressure plate first contacts the surface of the kraft paper bag material, and as the lifting frame continues to move downwards, the sliding part on the connecting plate moves upwards in the groove. The continuous movement of the sliding part compresses the spring, and the spring, under compression, generates a continuously increasing reaction force, causing the pressure plate to press and fix the kraft paper bag material firmly. After being tightened, the cutting blade cuts the kraft paper bag material, which facilitates the pressing and fixing of the kraft paper bag material before cutting, improving the stability of the kraft paper bag material cutting. By threading a knob support bolt into the bottom of the fastening frame, the knob support bolt supports the sliding part, leaving a gap between the pressure plate and the cutting platform for the kraft paper bag material to enter when the lifting frame is at the top of the support frame. Rotating the knob support bolt upwards causes the sliding part and the connecting plate to move synchronously, thereby increasing the gap between the pressure plate and the cutting platform, which facilitates the adjustment of the pressure plate height and is suitable for cutting and fixing kraft paper bag materials of different thicknesses.

[0010] Preferably, a support frame is fixed to the top of the cutting platform, and both ends of the support frame are fixed with first bolts threaded into the cutting platform.

[0011] Furthermore, a hydraulic rod connected to the lifting frame is fixedly installed at the top of the support frame, and positioning rods that are slidably inserted into the support frame are fixed on both sides of the top surface of the lifting frame.

[0012] Furthermore, a cutting blade located above the pressure plate is embedded in the bottom end of the lifting frame, and second bolts threaded into the cutting blade are installed at equal intervals on the side wall of the lifting frame.

[0013] Furthermore, the bottom end of the connecting plate is welded with a second connecting rod that is fixed to the pressure plate at equal intervals, and the top end of the pressure plate is welded with a first connecting rod that is fixed to the connecting plate at an angle.

[0014] Furthermore, a sliding groove is provided at the center of the side wall of the fastening frame, and a sliding part in a T-shape is fixed to the side wall of the connecting plate and inserted into the sliding groove.

[0015] Furthermore, the bottom end of the fastening frame is threaded with a knob support bolt that contacts the sliding part, and the top end of the fastening frame is inlaid with a spring that abuts against the sliding part.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention features a cutting blade fixed at the bottom of a lifting frame, with a pressure plate elastically mounted below the cutting blade on the side wall of the lifting frame via a fastening bracket. When cutting kraft paper bag material, the kraft paper bag material abuts against the baffle at the bottom of the pressure plate. A hydraulic rod drives the lifting frame to move downwards, and the pressure plate first contacts the surface of the kraft paper bag material. As the lifting frame continues to move downwards, the sliding part on the connecting plate moves upwards in the groove. The sliding part continuously compresses the spring, and the reaction force generated by the spring continuously increases, causing the pressure plate to press and fix the kraft paper bag material. After pressing and fixing, the cutting blade cuts the kraft paper bag material. This facilitates pressing and fixing the kraft paper bag material before cutting, improving the stability of cutting the kraft paper bag material.

[0019] By threading a knob support bolt into the bottom of the fastening frame, the knob support bolt supports the sliding part, leaving a gap between the pressure plate and the cutting platform for the kraft paper bag raw material to enter when the lifting frame is at the top of the support frame. Rotating the knob support bolt upwards causes the sliding part and the connecting plate to move synchronously, thereby increasing the gap between the pressure plate and the cutting platform, which facilitates the adjustment of the pressure plate height and is suitable for cutting and fixing kraft paper bag raw materials of different thicknesses.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This specific embodiment is a cutting device for processing kraft paper bags, and its structural schematic diagram is shown below. Figure 1 and Figure 2 As shown, the cutting device for processing kraft paper bags includes a cutting platform 1 and a lifting frame 7 set above the cutting platform 1. Kraft paper bag raw material 4 is set above the cutting platform 1. Fastening frames 12 are symmetrically fixed on the side wall of the lifting frame 7. A connecting plate 13 is elastically set between the two fastening frames 12. A pressure plate 2 for squeezing the kraft paper bag raw material 4 is fixed at the bottom end of the connecting plate 13. A baffle 15 that is slidably inserted into the cutting platform 1 is fixed at the end of the pressure plate 2 away from the lifting frame 7.

[0028] A support frame 10 is fixed to the top of the cutting platform 1. Both ends of the support frame 10 are fixed with first bolts 3 threaded into the cutting platform 1. A hydraulic rod 9 connected to a lifting frame 7 is fixed to the top of the support frame 10. Positioning rods 8, slidably inserted into the support frame 10, are fixed to both sides of the top surface of the lifting frame 7. A cutting blade 5, located above the pressure plate 2, is embedded in the bottom of the lifting frame 7. Second bolts 6, threaded into the cutting blade 5, are equidistantly installed on the side walls of the lifting frame 7. The kraft paper bag raw material 4 abuts against the baffle 15 at the bottom of the pressure plate 2. The hydraulic rod... 9 drives the lifting frame 7 to move downwards. The pressure plate 2 first contacts the surface of the kraft paper bag material 4. As the lifting frame 7 continues to move downwards, the sliding part 19 on the connecting plate 13 moves upwards in the slide groove 16. The sliding part 19 continuously compresses the spring 17. The spring 17 is compressed and the reaction force generated by it continues to increase, so that the pressure plate 2 presses and fixes the kraft paper bag material 4. After pressing and fixing, the cutting blade 5 cuts the kraft paper bag material 4. This makes it easier to press and fix the kraft paper bag material 4 before cutting, and improves the stability of cutting the kraft paper bag material 4.

[0029] like Figure 3 and Figure 4As shown, the bottom end of the connecting plate 13 is welded with second connecting rods 14 that are fixed to the pressure plate 2 at equal intervals. The top end of the pressure plate 2 is welded with first connecting rods 11 that are fixed to the connecting plate 13 at an incline. A groove 16 is provided at the center of the side wall of the fastening frame 12. A sliding part 19 with a T-shaped structure is fixed to the side wall of the connecting plate 13 and inserted into the groove 16. A knob support bolt 18 that contacts the sliding part 19 is threaded into the bottom end of the fastening frame 12. A spring 17 that abuts against the sliding part 19 is embedded in the top end of the fastening frame 12. The knob support bolt 18 supports the sliding part 19 so that when the lifting frame 7 is at the top of the support frame 10, there is a gap between the pressure plate 2 and the cutting platform 1 for the kraft paper bag raw material 4 to enter. Rotating the knob support bolt 18 upward causes the sliding part 19 and the connecting plate 13 to move synchronously, thereby increasing the gap between the pressure plate 2 and the cutting platform 1, which is convenient for adjusting the height of the pressure plate 2 and is suitable for cutting and fixing kraft paper bag raw materials 4 of different thicknesses.

[0030] Working principle: When using the device of this technical solution, when cutting the kraft paper bag raw material 4, the knob support bolt 18 supports the sliding part 19, so that when the lifting frame 7 is at the top of the support frame 10, there is a gap between the pressure plate 2 and the cutting platform 1 for the kraft paper bag raw material 4 to enter. The kraft paper bag raw material 4 is placed under the cutting blade 5, so that the kraft paper bag raw material 4 abuts against the baffle 15 at the bottom of the pressure plate 2. The hydraulic rod 9 is activated to drive the lifting frame 7 to move downward. The pressure plate 2 first contacts the surface of the kraft paper bag raw material 4. As the pressure plate 2 moves downward, it causes the baffle 15 to slide towards the bottom of the cutting platform 1. As the lifting frame 7 continues to move downward, the sliding part 19 on the connecting plate 13 moves upward in the slide groove 16. The movement of the sliding part 19 continuously compresses the spring 17. The spring 17 is compressed and the reaction force generated by it continues to increase, so that the pressure plate 2 presses and fixes the kraft paper bag material 4. After pressing and fixing, the cutting blade 5 cuts the kraft paper bag material 4. Before cutting, the kraft paper bag material 4 is pressed and fixed.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
