Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and specifically to a roller cutting device for cutting material packages. Background Technology

[0002] Roller cutting equipment is a type of automated equipment widely used in the food, pharmaceutical and daily necessities industries. Its main function is to cut strips of connected packaging bags and drop the cut bags onto the target items, such as seasoning packets in instant noodles and drying or preservation bags in medicine and food bags.

[0003] A search revealed a Chinese utility model patent with publication number CN209582095U, which discloses a high-speed baggage handling machine cutting device. The device includes a frame, a baggage conveyor inclinedly mounted on the frame, and a cutting assembly on the conveyor. The cutting assembly includes a cutting mounting frame mounted on the frame, a drive roller mounted on the mounting frame via bearings, and a driven roller mounting frame mounted on the mounting frame. The driven roller mounting frame also has a driven roller mounted on it via bearings. Both the drive and driven rollers are equipped with cutting blades. The drive and driven rollers are respectively positioned on the upper and lower sides of the conveyor. A cutting passage is provided in the conveyor between the drive and driven rollers. The drive and driven rollers are driven by the same cutting blade drive motor, moving in opposite directions. The material bag belt is supported by a conveyor belt during slitting, which prevents it from moving left or right or shifting, making the slitting more accurate and avoiding incorrect or missed cuts. At the same time, the cutter is easy to replace and maintain, with a low failure rate and high slitting efficiency.

[0004] The above technical solution still has at least the following technical problems in its implementation:

[0005] 1. When in use, when the cutter meets the material bag belt, the entire cutting edge of the cutter simultaneously abuts against the material bag belt. By driving the movement of the material bag belt and rotating the cutter, the material bag is cut. The entire cutting edge of the cutter contacts the material bag belt, and friction is generated when the cutting edge cuts the material bag belt. During high-speed operation, the temperature of the cutting edge of the cutter rises, which will reduce the service life of the cutter. Utility Model Content

[0029] Example

[0030] Please refer to Figures 1-4 This embodiment provides a roller cutting device for cutting material packages, including: a support 1; a material guiding mechanism, which includes a conveying unit 2 for conveying the material package to be cut and a pressure plate 3, both of which are mounted on the support 1, and a gap is formed between the conveying unit 2 and the pressure plate 3 to accommodate the material package to be cut; a cutting mechanism, which includes a base 4 for mounting a cutter 5, a cutter 5, and a guide roller 6, both of which are rotatably mounted on the support 1, and the cutter 5 is mounted on the base 4, with a material feeding gap formed between the base 4 and the guide roller 6, and the cutting edge of the cutter 5 can abut against the outer side wall of the guide roller 6; wherein, the cutter 5 includes a handle 501 embedded in the base 4 and a cutting edge 502 connected to the handle 501, and a gradually elongated wave groove 8 is provided on one side of the cutting edge 502, and a gradually shortened wave groove 7 is provided on the side of the cutting edge 502 away from the gradually elongated wave groove 8.

[0031] In this embodiment, the bracket 1 is used to support and install the material guiding mechanism and the cutting mechanism, so as to facilitate their coordinated operation and ensure the efficiency of material bag cutting.

[0032] In this embodiment, the aforementioned guiding mechanism is used to convey and guide the material package strip, facilitating orderly cutting and greatly improving cutting efficiency. Specifically, the aforementioned conveying unit 2 is used to drive the material package strip to move across the entire roller cutting device, causing the material package strip to be cut to the cutting edge of the cutter 5, thereby orderly cutting the material package strip to be separated. The aforementioned pressure plate 3 works in conjunction with the conveying unit 2 to confine the material package strip to be cut within a fixed space, preventing the material package strip from swinging or deviating, and improving the stability of the material package strip conveying.

[0033] In this embodiment, the cutting mechanism is used to cut a bag composed of multiple material packs into a single bag. Specifically, the base 4 is used to mount the cutter 5, the cutter 5 is used to separate the material packs, and the guide roller 6 is used to cooperate with the cutter 5 to cut the material packs, thereby improving the stability of the cutting.

[0034] In this embodiment, the lines connecting the cutting edges of the aforementioned cutter 5 intersect the central axis of the cutter 5. This allows the cutting edges of the cutter 5 to gradually contact the material package during cutting, reducing frictional heat between the cutting edges and the material package and extending the tool's lifespan. Specifically, both the elongated wave groove 8 and the shortened wave groove 7 are "V"-shaped structures. The elongated wave groove 8 and the shortened wave groove 7 formed on both sides of the cutting edge 502 create a cutting edge 502 inclined on the handle 501, making the cutting edge 502 form an acute angle with the central axis of the handle 501. This transforms the line contact between the cutting edge 502 and the material package into a progressive point contact, thereby reducing heat generation and extending its lifespan.

[0035] Please refer to Figures 1-3 In some embodiments of this example, the guide roller 6 is provided with a cutting strip 9, and the blade 502 can abut against the cutting strip 9.

[0036] In this embodiment, the cutting strip 9 is used to work in conjunction with the blade 502. During cutting, the material bag passes between the guide roller 6 and the base 4 where the cutter 5 is mounted. However, the gap between the two is much larger than the thickness of the material bag. By using the cutting strip 9 in conjunction with the blade of the cutter 5, the thickness of the part of the material bag to be cut is made greater than the gap between the blade and the cutting strip 9, thereby effectively cutting the material bag.

[0037] Please refer to Figures 1-3 In some embodiments of this example, the base 4 is connected to the support 1 via a shock-absorbing mechanism. The shock-absorbing mechanism includes a mounting beam 10, shock-absorbing rods 11, and a rotating seat 12. The mounting beam 10 is mounted on the support 1. There are two shock-absorbing rods 11, one end of which is fixed to the mounting beam 10. The rotating seat 12 is located at the end of the shock-absorbing rods 11 away from the mounting beam 10. Both ends of the base 4 are rotatably connected to the rotating seat 12.

[0038] In this embodiment, the aforementioned shock-absorbing mechanism is used to alleviate the elastic potential energy after the cutter 5 comes into contact with the cutting strip 9 through an elastic mechanism. It can also effectively prevent the rigid contact between the cutter 5 and the cutting strip 9 from directly damaging the blade 502, thereby effectively improving the service life of the cutter 5. Specifically, the aforementioned mounting beam 10 is used to mount the aforementioned shock-absorbing rod 11 and the rotating seat 12, and the aforementioned rotating seat 12 is used to support the rotation of the aforementioned base 4.

[0039] Please refer to Figure 1 and Figure 3 In some embodiments of this example, the support 1 is provided with a driving element 13, which is connected to the guide roller 6.

[0040] In this embodiment, the driving element 13 is used to drive the guide roller 6 to rotate. The rotating guide roller 6 causes the cutting strip 9 to rotate along with it, thereby driving the material bag to be cut to rotate and improving the stability of its cutting.

[0041] Please refer to Figure 1 In some embodiments of this example, a first gear 14 is provided between the driving element 13 and the guide roller 6, and a second gear 15 is provided on the rotating seat 12, with the first gear 14 and the second gear 15 meshing.

[0042] In this embodiment, the meshing of the first gear 14 and the second gear 15 can transmit the kinetic energy output by the drive element 13 to the rotating seat 12, causing the rotating seat 12 to move along with the rotation of the guide roller 6, so that the two work together to cut the material package evenly.

[0043] Please refer to Figure 2 In some embodiments of this example, the conveying unit 2 includes a conveyor belt 201 and a tension roller 202. There are two tension rollers 202, which are rotatably mounted on the support 1. The conveyor belt 201 is connected to the two tension rollers 202 respectively, and any tension roller 202 is connected to the driving element 13.

[0044] In this embodiment, the conveyor belt 201 is used to support the material package to be cut, and to transport and guide the material package so that it can smoothly enter the cutting position. The tension roller 202 is used to tension the conveyor belt 201, thereby facilitating the conveyor belt 201 to obtain power for circumferential movement.

[0045] Please refer to Figure 3 In some embodiments of this example, the pressure plate 3 is mounted on the support 1 via a crossbar 16, and the pressure plate 3 is provided with a keyway 17 for adjusting the distance between the pressure plate 3 and the conveying unit 2.

[0046] In this embodiment, the crossbeam is used to install the pressure plate 3, and the keyway 17 is used to accommodate the screw. The pressure plate 3 is fixed to the crossbeam by the nut of the screw abutting against the surface of the pressure plate 3. The keyway 17 is used to adjust the distance between the pressure plate 3 and the conveyor belt 201, so that it can be used for material bags of different thicknesses, thereby improving its applicability to convey material bags.

[0047] In use, the end of the material bag to be cut is passed through the gap of the material guide mechanism that accommodates the material bag to be cut, and then the material bag to be cut is pulled to the material feeding gap, aligned with the pre-cut position on the material bag, and the drive element 13 is turned on. The drive element 13 drives the guide roller 6 to rotate, and the rotating guide roller 6 drives the base 4 to rotate. The material bag to be cut moves synchronously to cut into individual material bags.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
