[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Example 1

[0023] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a fixed-length longitudinal shearing device, comprising two groups of fixed frames 1, two groups of rotating rollers 2 are arranged between the inner surface walls of the two groups of fixed frames 1, one end of the side of the two groups of rotating rollers 2 is fixedly connected to the second motor 7, the outer wall of the two groups of rotating rollers 2 is provided with multiple groups of shearing tools 16, the tops of the two groups of fixed frames 1 are fixedly connected to support rods 3, the outer walls of the support rods 3 are provided with threaded rods 18, the outer walls of the threaded rods 18 are threadedly connected to sliding rods, the outer walls of the sliding rods are fixedly connected to first blocking plates 5, the outer walls of the first blocking plates 5 are fixedly connected to jet devices 6, the outer walls of the jet devices 6 are provided with multiple jet heads 17, two second blocking plates 15 are fixedly connected between the inner surface walls of the two groups of fixed frames 1, the bottom of one of the two groups of fixed frames 1 is slidably connected to a collecting box 13, the outer wall of the collecting box 13 is fixedly connected to a handle 14, and the top of the threaded rod 18 is fixedly connected to the first motor 4.

[0024] In this embodiment, the objects to be longitudinally sheared are first transported to the inner surface wall of the two sets of fixed frames 1, and then the second motor 7 is started at the top of the support rod 3 (the second motor 7 adopts a servo motor), which drives the rotating roller 2 to rotate, and at the same time drives the shearing tool 16 to rotate, and performs a rotary shearing operation on the objects to be longitudinally sheared. When the longitudinal shearing operation is performed, debris residues will be generated, and the generated debris residues will fall downward due to the influence of gravity, and then under the action of the collecting box 13, the fallen debris residues can be collected at the bottom of the two sets of fixed frames 1, and under the action of the second blocking plate 15, the debris residues will not float out of the range of the collecting box 13 when they fall, thereby ensuring the collection efficiency of the debris residues, preventing the debris residues from falling to the bottom of the two sets of fixed frames 1 and being unable to be cleaned conveniently, thereby improving work efficiency. After the longitudinal shearing operation is completed, the outer wall of the shearing tool 16 will be adhered to the debris residues, and then The first motor 4 is started to drive the threaded rod 18 to rotate, and at the same time drive the sliding rod and the first blocking plate 5 to move downward (the first motor 4 adopts a forward and reverse motor), so that the multiple nozzles 17 are respectively close to the multiple groups of longitudinal shearing tools 16, and then the nozzle device 6 is started, and the nozzle head 17 is used to clean the debris and residues adhered to the outer wall of the shearing tool 16. When the cleaning operation is performed, the speed of the second motor 7 is reduced to the minimum speed, and then with the cooperation of the first blocking plate 5, it is ensured that the debris cleaned by the nozzle head 17 will not float during the cleaning operation, thereby improving the collection efficiency of the debris and residue, and eliminating the need for workers to manually clean the shearing tool 16, thereby improving work efficiency. When it is necessary to clean the debris and residue inside the collection box 13, the staff pulls the handle 14 to pull the collection box 13 out from the bottom of the fixed frame 1, so that the debris and residue inside the collection box 13 can be easily cleaned, saving working time and improving work efficiency.

[0025] Example 2

[0026] like Figure 1-Figure 4 As shown, the outer walls of the two groups of fixing frames 1 are fixedly connected with a base 8, the top of the base 8 is fixedly connected with two groups of limiting plates 9, the top of the two groups of limiting plates 9 is fixedly connected with a cutting device 10, the outer wall of the cutting device 10 is provided with a displacement sensor 11, and the bottom of the base 8 is fixedly connected with four supporting legs 12.

[0027] In this embodiment, through the cooperation of the base 8 and the limiting plate 9, after the items to be longitudinally sheared are longitudinally sheared, the driving force generated by the subsequent forward conveying of the sheared items pushes the sheared items to the cutting device 10, and the limiting plate 9 can limit the conveying position of the longitudinally sheared items to prevent them from falling, thereby ensuring the safety of transportation. Then, when the longitudinally sheared items reach the displacement sensor 11 (the displacement sensor 11 adopts GFL-Z30N-RS485) and exceed a certain range, the displacement sensor 11 transmits a signal to the external controller, and the external controller is used to control the cutting device 10 to start, cut the longitudinally sheared items, and realize equidistant cutting operations. Then, under the action of the supporting legs 12, the items after the longitudinal shearing operation can be stably conveyed to ensure the conveying efficiency.

[0028] The working principle of this embodiment is as follows: first, the articles to be longitudinally sheared are transported to the inner surface walls of the two sets of fixed frames 1, and then the second motor 7 is started at the top of the support rod 3 to drive the rotating roller 2 to rotate, and at the same time drive the shearing tool 16 to rotate, and perform a rotary shearing operation on the articles to be longitudinally sheared. During the longitudinal shearing operation, the debris residue will fall, and the fallen debris residue is collected by the collection box 13. When the debris residue falls, the first blocking plate 5 and the second blocking plate 15 cooperate to prevent the debris residue from falling outside the collection range of the collection box 13. During the longitudinal shearing operation, debris and residue will adhere to the outer wall of the shearing tool 16, so the jet device 6 is started, and the jet head 17 is used to clean the debris and residue adhered to the outer wall of the shearing tool 16. During the cleaning operation, the speed of the second motor 7 is reduced to the minimum speed, so that the rotation speed of the shearing tool 16 is slowed down, so that the debris and residue that fall during cleaning will not float out of the collection range of the collection box 13 due to the excessively fast rotation speed. After the cleaning operation is completed, the staff pulls the handle 14 to pull out the collection box 13, and cleans the debris and residue inside the collection box 13.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
