[0002] A straw is a device used to suck liquid from a container, and rice straws are increasingly used as edible and environmentally friendly straws. During production, rice straws need to be cut according to demand. In actual daily use, not only are some straws straight, but some also need to have a slanted end to pierce the seal of drinks.
[0003] However, the existing rice straw cutting machine needs to cut straight first, and then cut one end of the straw at an angle in the subsequent process. It cannot cut into shape in one step, requires the cooperation of multiple processes, and has low production efficiency. Utility Model Content
[0004] In order to solve the above technical problems, the utility model provides a new straight and oblique dual-purpose rice straw cutting machine to solve the problem that the existing rice straw cutting machine needs to perform straight cutting first and then bevel cutting one end of the straw in the subsequent process, which cannot be cut into shape in one time and requires the cooperation of multiple processes, resulting in low production efficiency.

DETAILED DESCRIPTION
[0018] In order to help those skilled in the art better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.
[0019] As attached Figure 1 To the attached Figure 5shown.
[0020] The utility model provides a novel straight and oblique dual-purpose rice straw cutting machine, comprising a bracket 1, and a conveyor belt 2 installed on the inner side of the bracket 1 through a rotating shaft provided at both ends. The characteristics are: one end of the outer side surface of the bracket 1 is installed with a transmission motor 3 for driving the rotating shaft to rotate, and one end above the bracket 1 is fixedly installed with a leveling roller 4. The rice straw has elasticity and ductility before drying and shaping. After being cut by the cutter, the straw will have an elastic change toward the rear. The leveling roller 4 can be used to squeeze the rice straw, so that the straws extruded by the extruder can be aligned, and after being cut by the cutter, it can prevent The uncut straws are extended and retracted backward so that the lengths of the straws after being cut are consistent. A straight cutting mechanism 5 is fixedly installed above the bracket 1 and on one side of the leveling roller 4. The straight cutting mechanism 5 can cut one end of the rice straw into a flat shape. A beveling mechanism 6 with an adjustable distance from the straight cutting mechanism 5 is movably installed on the other end above the bracket 1. The beveling mechanism 6 can cut one end of the rice straw into an oblique shape. By moving and controlling the beveling mechanism 6, not only the cutting length of the rice straw can be adjusted, but also whether the beveling mechanism 6 cuts one end of the rice straw into an oblique shape can be controlled according to demand.
[0021] A cylinder 51 is fixedly installed in the middle position of the upper surface of the straight cutting mechanism 5 by bolts, and a straight cutting knife 52 connected to the cylinder 51 is fixedly installed on the lower surface of the straight cutting mechanism 5. The straight cutting knife 52 can move vertically up and down to cut the rice straw flat. Rectangular linkage plates 53 are welded and fixedly installed at both ends of the upper surface of the straight cutting knife 52.
[0022] A bevel cutter 61 is movably mounted below the bevel cutting mechanism 6. The upper end of the bevel cutter 61 is in movably contact connection with the lower surface of the linkage plate 53. When the upper end of the bevel cutter 61 is below the linkage plate 53, driven by the cylinder 51, the straight cutter 52 and the bevel cutter 61 can simultaneously perform synchronous straight or bevel cutting on the rice straw. When the upper end of the bevel cutter 61 deviates from the lower side of the linkage plate 53, the linkage plate 53 cannot press the bevel cutter 61 downward. At this time, driven by the cylinder 51, only the straight cutter 52 performs straight cutting on the rice straw. Both ends of the bevel cutter 61 are welded with guide grooves 63 with an angle of 30-40 degrees, which are embedded in the two inner side surfaces of the bevel cutting mechanism 6. The rectangular guide block 62 can also be a circular structure. The bevel cutter 61 can be tilted and moved along the guide groove 63 through the guide block 62 to cut the rice straw at an angle. The two guide grooves 63 are fixedly installed with guide posts 64 that vertically penetrate the guide block 62. The guide posts 64 can guide the movement of the bevel cutter 61. At the same time, if a circular guide block 62 is used, it can also prevent the guide block 62 from rotating during the movement. A carbon spring steel spring 65 is wound around the outside of the guide post 64 and located below the guide block 62. The spring 65 can push the bevel cutter 61 to move upward along the inclination angle of the guide groove 63 under the action of its own elastic force and return to its original position.
[0023] Both sides of the bracket 1 are welded with "U"-shaped guide rails 7, and both ends of the beveling mechanism 6 are welded with rectangular sliders 66 embedded in the guide rails 7. The beveling mechanism 6 can slide along the guide rails 7 above the conveyor belt 2 through the sliders 66. Example 1:
[0024] When rice straws need to be cut into straws with an oblique end and a straight end, the position of the beveling mechanism 6 is first adjusted according to the length of the rice straws to be cut, and the beveling mechanism 6 is first moved to a suitable position along the guide rail 7 by the slider 66. At this time, one end of the lower surface of the linkage plate 53 contacts the upper end of the beveling knife 61. Then, the time frequency of the up and down extension of the cylinder 51 is adjusted by the controller. Then, the rice straws to be cut are driven by the conveyor belt 2 and first pass through the leveling roller 4. The leveling roller 4 squeezes the rice straws extruded by the extruder on the conveyor belt 2 to align the rice straws. Then, driven by the conveyor belt 2, the rice straws pass through the straight cutting mechanism 5 and the beveling mechanism 6 in sequence. When the rice straws on the conveyor belt 2 move to a suitable position, the conveyor belt 2 stops running, and the cylinder 51 receives a signal. Then, the cylinder 51 pushes the straight cutting knife 52 to stretch downward. At the same time, the straight cutting knife 52 squeezes the beveling knife 61 downward through the linkage plate 53. Then, the beveling knife 61 moves downward obliquely along the guide groove 63 to align the straight cutting knife. 52 and the bevel cutter 61 move downward at the same time to complete the straight cutting and bevel cutting of the two ends of the rice straw at the same time, forming it in one step. At this time, the leveling roller 4 still squeezes the uncut straw to prevent the uncut straw from stretching backward. When the cutting of the rice straw is completed, the cylinder 51 pulls the straight cutter 52 to retract upward, and then the straight cutter 52 drives the linkage plate 53 to move upward. The pressure of the linkage plate 53 on the bevel cutter 61 is gradually reduced, and then the bevel cutter 61 passes through the slider 6 under the action of the elastic force of the spring 65. 6 moves upward along the guide groove 63 and the guide post 64 until the straight cutter 52 and the bevel cutter 61 return to their original positions, and then the conveyor belt 2 continues to run, driving the rice straws above to continue to move. The cut rice straws are moved out from under the straight cutting mechanism 5 and the bevel cutting mechanism 6, and then the uncut rice straws at the rear are moved to under the straight cutting mechanism 5 and the bevel cutting mechanism 6, and the above steps are repeated, using the straight cutter 52 and the bevel cutter 61 to continue straight cutting and bevel cutting the rice straws to be cut. Example 2:
[0025] If the rice straws only need to be cut into straight ends, the beveling mechanism 6 is first moved to a suitable position along the guide rail 7 by the slider 66. At this time, the linkage plate 53 is separated from the beveling knife 61. Then, the time frequency of the up and down extension of the cylinder 51 is adjusted by the controller. Then, the rice straws to be cut are driven by the conveyor belt 2 and first pass through the leveling roller 4. The leveling roller 4 squeezes the rice straws on the conveyor belt 2 to align the rice straws. Then, driven by the conveyor belt 2, the rice straws are moved to a suitable position below the straight cutting mechanism 5. Then, the conveyor belt 2 stops running, and then the cylinder 51 pushes the straight cutting knife 52 to stretch downward to cut one end of the rice straw. After the rice straws are cut straight, the leveling roller 4 still squeezes the uncut straws to prevent the uncut straws from stretching backwards. The cylinder 51 then pulls the straight cutter 52 to retract upwards until the straight cutter 52 returns to its original position. The conveyor belt 2 then continues to operate, driving the rice straws above to continue moving. The rice straws after cutting are moved out from below the straight cutting mechanism 5 and the beveling mechanism 6 to the other end and enter the next link equipment. The uncut straws at the rear are then moved to below the straight cutting mechanism 5. The above steps are repeated, and the straight cutter 52 is utilized to continue straight cutting the rice straws that need to be cut.
