[0030] 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.

[0031] Example: Please refer to Figure 1-10 This utility model provides a technical solution: a cutting machine with a noise reduction structure, including a frame body 1 and a mounting base 2. The mounting base 2 is fixed to the middle of the frame body 1 by bolts. The two sides of the frame body 1 are rotatably connected to a winding shaft 6, which can facilitate the winding and conveying of the roll material to be cut.

[0032] Please see Figure 1-4 The main body of the frame 1 is equipped with a take-up shaft 8 and a release shaft 7 on the lower left and lower right sides, respectively. The take-up shaft 8 can pull the remaining material to be cut after cutting to rewind, and the take-up shaft 8 can also facilitate the gradual release of the uncut roll material. The whole process is automatic and has a high degree of automation. Figure 2 The dotted line area can be used to place a frame for receiving cut materials.

[0033] It is worth noting that the winding shaft 6 is located above the take-up shaft 8 and the unwinding shaft 7, and the center lines of the winding shaft 6, the take-up shaft 8, and the unwinding shaft 7 are parallel to each other. The drive shaft 52 and the take-up shaft 8 are both rotatably connected to the frame body 1, and the drive shaft 52 and the take-up shaft 8 are at the same height.

[0034] Furthermore, a hydraulic cylinder 3 is fixedly installed in the middle of the mounting base 2, and a cutting plate 22 is provided inside the mounting base 2. A protective component 21 is fixedly installed at the lower end of the cutting plate 22. The output shaft of the hydraulic cylinder 3 and the cutting plate 22 are fixedly installed. Guide rods 4 are fixedly installed on both the left and right sides of the cutting plate 22. After the hydraulic cylinder 3 works, the cutting plate 22 can move up or down inside the mounting base 2 through the guiding action of the guide rods 4, thereby realizing the cutting of the material to be cut.

[0035] Please see Figure 1 , Figure 5 , Figure 7 and Figure 8 The mounting base 2 has symmetrical linkage components 5 on its left and right sides, which facilitate the transmission of force. The drive shaft 52 is fixedly mounted on the back of the frame body 1 by bearings. The mounting base 2 has a slot 20 for engaging the drive shaft 52. The drive shaft 52 and the take-up shaft 8 are connected by a belt drive assembly 9.

[0036] Specifically, the linkage component 5 includes a connecting rod 51, with a push rod 56 at its lower end. The connecting rod 51 has an "L"-shaped longitudinal section and is movably connected to the mounting base 2. The connecting rod 51 and the guide rod 4 are fixedly installed via an adapter sleeve 55. The adapter sleeve 55 has piston plates 57 on one side corresponding to both the push rod 56 and the guide rod 4. It is worth noting that the adapter sleeve 55 is filled with a certain amount of oil, the amount of which is less than the storage capacity of the space formed by the adjacent piston plates 57.

[0037] A rack seat 53 is fixedly installed at the lower end of the connecting rod 51. A sector gear 54 is meshed inside the rack seat 53 and is fixedly installed on the drive shaft 52. The distribution range of the teeth on the sector gear 54 is between 90 and 180 degrees. During use, the hydraulic cylinder 3 moves downward, and through the guiding action of the guide rod 4, the cutting plate 22 can move downward inside the mounting base 2. At this time, the guide rod 4 drives the piston plate 57 at its end to move downward inside the adapter sleeve 55. Since the volume of the oil is smaller than the storage volume of the space formed by the adjacent piston plates 57, the linkage component 5 will not operate, which facilitates the cutting machine. The material to be cut is cut; similarly, after the hydraulic cylinder 3 has finished cutting, the piston rod retracts into the cylinder body of the hydraulic cylinder 3. At this time, the cutting plate 22 moves from bottom to top, which can drive the guide rod 4 to move. After the guide rod 4 moves, the distance between adjacent piston plates 57 gradually decreases, and the volume of the space they form decreases. When the amount of oil is equal to the volume of the space formed by adjacent piston plates 57, the guide rod 4 moves, which can cause the push rod 56 to drive the connecting rod 51 to move from bottom to top. At this time, the rack seat 53 moves, and through the meshing of the rack seat 53 and the sector gear 54, the sector gear 54 rotates, which in turn drives the drive shaft 52 to rotate.

[0038] Please see Figure 7 and Figure 9 The frame body 1 has support legs 101 arranged in a square pattern below it, and shock-absorbing components 100 are installed below the support legs 101. The belt drive assembly 9 is located outside the symmetrical linkage assembly 5, and both the belt drive assembly 9 and the linkage assembly 5 are located on the front and rear sides of the frame body 1. The belt drive assembly 9 includes two pulleys and a drive belt. The pulleys are fixed to the corresponding shafts, and the drive belt is used to connect the two pulleys. After the drive shaft 52 rotates, the take-up shaft 8 rotates through the connection of the belt drive assembly 9, which can reel in the cut residual material. At the same time, it can also facilitate the conveying of new material to be cut to the area below the cutting board 22.

[0039] Specifically, the shock-absorbing assembly 100 includes a snap-fit ​​seat 100-1, with a pad 100-2 on the lower end face of the snap-fit ​​seat 100-1. The pad 100-2 has anti-slip texture, which increases the stability of the cutting machine. A connector rod 100-3 is fixedly installed in the center of the inner cavity of the snap-fit ​​seat 100-1. A socket 102 for the connector rod 100-3 to be movably inserted is provided on the lower end face of the support leg 101. The snap-fit ​​seat 100-1 is movably sleeved on the lower end of the support leg 101. A spring 100-4 is movably sleeved on the connector rod 100-3. During the operation of the cutting machine, when vibration occurs, the elasticity of the spring 100-4 reduces the vibration of the cutting machine, thereby further reducing the noise during operation.

[0040] Please see Figure 1 and Figure 10 The protective component 21 includes a support plate 21-1, which is U-shaped with an opening facing downwards and spans across the cutting plate 22. Support rods 21-3 are fixedly installed on both the left and right sides of the upper surface of the cutting plate 22. The support plate 21-1 is movably sleeved on the support rods 21-3. A second spring 21-4 is movably sleeved on the support rods 21-3, located below the support plate 21-1. A soundproof transparent cover 21-2 is fixedly installed at the lower end of the support plate 21-1 and movably sleeved below the cutting plate 22. The support rods 21-3 are located between adjacent guide rods 4, and the center lines of the support rods 21-3 and guide rods 4 are parallel to each other. During the use of the cutting machine, the soundproof transparent cover 21-2 isolates noise from being transmitted to the outside, and the setting of spring 21-4 can further improve the tightness of the soundproof transparent cover 21-2 and the material to be cut, thereby further ensuring the effectiveness of the soundproof transparent cover 21-2.

[0041] Working principle: Before use, this type of cutting machine with a noise reduction structure places the roll of material to be cut on the feeding shaft 7, ensuring that the roll of material to be cut moves as... Figure 1The cutting plate 22 is wrapped around the main body 1 of the frame and around the take-up shaft 8. In use, the hydraulic cylinder 3 is activated, causing it to move downwards. Guided by the guide rod 4, the cutting plate 22 moves downwards inside the mounting base 2. At this time, the guide rod 4 drives the piston plate 57 at its end to move downwards inside the adapter sleeve 55. Because the volume of the oil is smaller than the storage volume of the space formed by the adjacent piston plates 57, the linkage component 5 will not move, facilitating the cutting machine to cut the material. Conversely, after the hydraulic cylinder 3 completes the cutting, the piston rod retracts into the cylinder body of the hydraulic cylinder 3. At this time, the cutting plate 22 moves upwards, driving the guide rod 4 to move. After the guide rod 4 moves, the distance between the adjacent piston plates 57... As the volume of oil gradually decreases, the volume of the space formed by the oil decreases. When the volume of oil equals the volume of the space formed by the adjacent piston plates 57, the guide rod 4 moves, which causes the push rod 56 to drive the connecting rod 51 to move from bottom to top. At this time, the rack seat 53 moves, and through the meshing of the rack seat 53 and the sector gear 54, the sector gear 54 rotates, which in turn drives the drive shaft 52 to rotate. After the drive shaft 52 rotates, through the connection of the belt drive assembly 9, the take-up shaft 8 rotates, which can reel in the cut residual material. At the same time, it can also facilitate the delivery of new material to be cut to the bottom of the cutting plate 22. There is no need for manual loading and unloading, the degree of automation is high, and the return stroke of the hydraulic cylinder 3 is used to improve the utilization rate of resources. It is worth promoting and using.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
