DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figures 1 to 5 As shown, a cutting device for a polypropylene tie rod 8 comprises a cutting table 2, and the cutting table 2 comprises a driving frame 3, a positioning seat 4 and a placing seat 5; the driving frame 3 is fixed on the cutting table 2, and the driving frame 3 has a first mounting plate 31 and a second mounting plate 32, and the mounting directions of the first mounting plate 31 and the second mounting plate 32 are perpendicular, and the first mounting plate 31 has a lifting motor 33, and a lifting plate 34 is fixed on the lifting rod of the lifting motor 33, and a sliding groove 321 is provided on the second mounting plate 32, and the sliding groove 321 is slidably arranged with the lifting plate 34, so as to drive the lifting plate 34 to rise and fall, and a third mounting plate 35 is installed at the bottom of the lifting plate 34 A driving motor 36 is installed on one side of the third mounting plate 35, and the output shaft of the driving motor 36 is connected to the cutting wheel 37; a positioning cylinder 41 is provided on the positioning seat 4, and the positioning cylinder 41 is connected to the pull rod 8; the placement seat 5 is fixed on the cutting table 2, and the center of the placement seat 5 in the front and rear directions has a spacing bar 51, and a plurality of second guide rails 52 are arranged and installed in the direction toward the front side with the spacing bar 51 as the center, and a first clamping block 53 is slidably arranged on the second guide rail 52, and a second guide rail 52 is also arranged and installed in the direction toward the rear side with the spacing bar 51 as the center, and a second clamping block 54 is slidably arranged on the second guide rail 52 for clamping the pull rod 8.

[0023] With the above structure, the placement tube has a hole that matches the rod diameter of the pull rod 8. The pull rod 8 is first inserted into the hole of the placement tube, and the pull rod 8 is placed horizontally on the placement seat 5. The first clamping block 53 and the second clamping block 54 on the placement seat 5 are moved by the second guide rails 52 set on the front and rear sides of the spacer bar 51, and move toward the direction close to the spacer bar 51. At the same time, the first clamping block 53 and the second clamping block 54 are provided with a limiting portion for overlapping with the spacer bar 51 on one side close to the spacer bar 51, so that the first clamping block 53 and the second clamping block 54 are combined together to clamp and fix the pull rod 8, which is conducive to firm clamping and good clamping effect; at the same time, the lifting motor 33 drives the lifting plate 34 to move downward, and the driving motor 36 on the third mounting plate 35 at the bottom of the lifting plate 34 is started, driving the cutting wheel 37 to rotate, and cutting the pull rod 8. The first clamping block 53 and the second clamping block 54 clamp one side of the pull rod 8, and the placement tube positions the other end of the pull rod 8, which is conducive to better fixing the pull rod 8 when cutting the pull rod 8, fixing it firmly, and preventing the pull rod 8 from tilting or vibrating.

[0024] Specifically, if Figures 1 to 5 As shown, a chip retaining groove 6 is also installed at the bottom of the driving frame 3 to catch the debris generated during cutting.

[0025] By adopting the above structure and setting the chip retention groove 6, the debris impurities generated when the cutting wheel 37 cuts from the pull rod 8 fall into the chip retention groove 6, which is conducive to facilitating the collection of debris impurities and avoiding the debris impurities from remaining on the cutting table 2 and affecting the cleanliness of the table surface.

[0026] like Figures 1 to 5 As shown, the chip retaining groove 6 is inclined downward from the direction close to the driving frame 3 to the direction away from the driving frame 3. By providing the inclined surface, it is helpful to prevent the accumulation of debris and impurities directly below the cutting wheel 37, and it is convenient to collect the debris and impurities.

[0027] like Figures 1 to 5 As shown, two support blocks 7 are also included, which are installed on the left and right sides of the chip retention groove 6. The support blocks 7 have support through holes 71 for supporting the pull rod 8. By providing support blocks 7 on both sides of the chip retention groove 6, it is beneficial to better support the pull rod 8 and prevent the pull rod 8 from vibrating.

[0028] like Figures 1 to 5 As shown, when the first clamping block 53 and the second clamping block 54 are simultaneously pressed against the spacer bar 51, they can jointly form a clamping seat 551, and the clamping seat 551 has a clamping through hole 55 for clamping the pull rod 8. By providing the clamping seat 551, the wall of the clamping through hole 55 on the clamping seat 551 is also provided with a shock-absorbing pad 9, which is conducive to better clamping the pull rod 8 and has a better shock-absorbing effect.

[0029] like Figures 1 to 5 As shown, the positioning cylinder 41, the supporting through hole 71 and the clamping through hole 55 are located on a horizontal axis at the same height.

[0030] like Figures 1 to 5 As shown, the front and rear sides of the top of the placement seat 5 are also equipped with limiting plates 56 for limiting the first clamping block 53 and the second clamping block 54. The limiting plates 56 are helpful to limit the distance between the first clamping block 53 and the second clamping block 54.

[0031] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0032] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. At the same time, the meaning of "and / or" appearing in the full text is that it includes three schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0033] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0034] The specific embodiments described herein are merely examples of the spirit of the present invention. A person skilled in the art of the present invention may make various modifications or additions to the specific embodiments described or replace them in a similar manner, but this will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
