[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Such as Figures 1 to 3As shown in the figure, the utility model provides a stable fixing mechanism for continuous processing of corrugated pipes, including a base 1; two groups of fixing seats 10 are fixedly connected to the top of the base 1; every two of the fixing seats 10 form a group; the two fixing seats 10 are arranged oppositely; an electric push rod 11 is fixedly connected to the middle of the fixing seat 10; a push plate 12 is fixedly connected to the output end of the electric push rod 11; a plurality of grooves 13 are formed in the middle of the push plate 12; a spring 14 is fixedly connected to the middle of the groove 13; the ends of the two springs 14 are fixedly connected with fixing clamping plates 16; the fixing clamping plates 16 are elastically arranged; two buffer heads 15 are fixedly connected to the middle of the fixing clamping plates 16; the buffer heads 15 are fixedly connected inside the spring 14; during operation, after a plurality of electric push rods 11 are powered on and started, when the corrugated pipe moves continuously through the conveyor, it first passes between the two groups of push plates 12. After the corrugated pipe moves to the designated position for processing, the output ends of the two groups of electric push rods 11 are controlled to stretch towards the corrugated pipe, so that the output ends of the electric push rods 11 move the push plate 12 towards the middle of the corrugated pipe. The two relatively opposed fixing clamping plates 16 contact both sides of the corrugated pipe. The fixing clamping plates 16 are arc-shaped and fit the surface of the corrugated pipe. Under the continuous push of the electric push rod 11, the spring 14 is elastically contracted into the groove 13 under pressure, and at the same time, the end of the buffer head 15 enters the groove 13 and abuts against the end of the groove 13 for limiting. The contact pressure of the fixing clamping plate 16 on the corrugated pipe is adjusted by the spring 14. The corrugated pipe is clamped and fixed by a plurality of fixing clamping plates 16, and then the corrugated pipe is processed. In this step, the spring 14 and the fixing clamping plate 16 are used in cooperation to fix the corrugated pipe, effectively providing a stable clamping force for the processing of the corrugated pipe, enabling the corrugated pipe not to be displaced or shaken due to external force or vibration during the processing, effectively reducing the processing precision error caused by shaking or moving during the processing, and effectively dispersing the stress generated during the clamping process of the corrugated pipe processing through the cooperation of the spring 14 and the buffer head 15. The pressure of the fixing clamping plate 16 on the corrugated pipe can be adjusted, effectively reducing the damage of the corrugated pipe caused by excessive local stress and reducing the scratches and abrasions on the surface of the corrugated pipe.

[0023] As Figures 1 to 3As shown, a sliding groove 2 is formed inside the fixed clamping plate 16; a plurality of limiting grooves 21 are formed in the middle of the fixed clamping plate 16; the plurality of limiting grooves 21 are formed in the middle of the sliding groove 2; a plurality of sliding plates 22 are slidably connected in the middle of the sliding groove 2; a clamping pad 23 is fixedly connected in the middle of the sliding plate 22; the clamping pad 23 is arranged in the middle of the limiting groove 21; both the sliding plate 22 and the clamping pad 23 are elastically arranged; during operation, when the fixed clamping plate 16 clamps and fixes the corrugated pipe, the clamping pad 23 enters the corresponding concave position of the corrugated pipe. When the clamping pad 23 contacts the convex position of the corrugated pipe, the clamping pad 23 slides inside the sliding groove 2 and the limiting groove 21 along the convex part of the corrugated pipe through the sliding plate 22, so as to finely adjust the position of the clamping pad 23 in the middle of the limiting groove 21. This step can accurately embed the clamping pad 23 into the concave part of the corrugated pipe through the movement of the clamping pad 23 in the middle of the limiting groove 21, forming a closer contact surface, effectively increasing the friction force between the clamping point and the corrugated pipe, thereby effectively improving the stability of the fixation during the continuous processing of the corrugated pipe, keeping the corrugated pipe in a stable clamping state, and not easily causing the corrugated pipe to displace and fall off during the processing.

[0024] As Figure 1 , Figure 4 , Figure 5As shown, two groups of fixing rods 3 are fixedly connected to the top of the base 1; every two of the fixing rods 3 form a group; the two groups of fixing rods 3 are arranged oppositely; a sleeve 31 is rotatably connected to the middle of the fixing rod 3; a baffle 32 is fixedly connected to the middle of the sleeve 31; one end of the top of the baffle 32 is fixedly connected to a support rod 33; a roller 34 is rotatably connected to the middle of the support rod 33; two groups of moving grooves 35 are opened at the top of the base 1; a slider 36 is slidably connected to the middle of the moving groove 35; the end of the support rod 33 is fixedly connected to the top of the slider 36; an elastic rope 37 is fixedly connected between the middle of the slider 36 and one end of the moving groove 35; during operation, when the bellows is continuously moving and being processed, when the bellows deviates from the central position, the end of the bellows is guided by the two support rods 33 at one end, so that the bellows enters between the two rollers 34. After the middle of the bellows contacts the two rollers 34, the two rollers 34 are squeezed to both sides. When the roller 34 moves to one side, the sleeve 31 rotates in the middle of the fixing rod 3. At the same time, the bottom end of the support rod 33 drives the slider 36 to slide in the middle of the moving groove 35. When the slider 36 slides, the elastic rope 37 is elastically stretched under tension. The end of the bellows then moves between the two rollers 34 at the other end of the top of the base 1. When the bellows is moving, the two rollers 34 on both sides rotate in the middle of the support rod 33 at the same time. Through the two rollers 34, the bellows is kept in the central position during continuous processing and movement. When the processing of the bellows is completed, the roller 34 is reset by the elastic contraction of the elastic rope 37. This step can accurately position the bellows at the center of the processing path through the cooperation of the support rod 33 and the roller 34, effectively reducing the processing error caused by the position deviation of the bellows, being able to maintain the consistency of the processing dimensions of the bellows during continuous processing, effectively improving the stability of the production quality of the bellows, and effectively reducing the time and manpower required for frequent adjustment due to position deviation.

[0025] As Figure 4 shown, a plurality of bristles 4 are fixedly connected to the middle of one group of the rollers 34; the plurality of bristles 4 are evenly distributed in the middle of the roller 34; during operation, when the bellows is fixedly processed and completed and passes between the two rollers 34 at one end, the plurality of bristles 4 contact the surface of the bellows. When the roller 34 rotates, the surface of the bellows is cleaned by the plurality of bristles 4. This step can effectively brush off the dust and tiny impurities on the surface of the bellows through the bristles 4, effectively maintaining the cleanliness of the bellows. Through the contact between the soft material of the bristles 4 and the surface of the bellows, the scratches generated by friction during the cleaning process of the bellows are effectively reduced, and the quality of the surface of the bellows is effectively protected.

[0026] As Figure 1 and Figure 4As shown, a dust collector 5 is fixedly connected to the side wall of the base 1; the dust collector 5 is fixedly connected near one end of the brush bristles 4; a connecting pipe 51 is fixedly connected to the middle of the dust collector 5; a dust suction pipe 52 is fixedly connected to the end of the connecting pipe 51; the middle of the dust suction pipe 52 is fixedly connected to the side wall of the base 1; a collection groove 54 is formed at the top of the base 1; a through groove 53 is formed in the middle of the dust suction pipe 52 and the side wall of the base 1; the middle of the through groove 53 communicates with one side of the collection groove 54; during operation, the side of the collection groove 54 close to the roller 34 is inclined. When the brush bristles 4 clean the surface of the corrugated pipe, the debris and impurities on the surface of the corrugated pipe enter the middle of the collection groove 54 along one side of the collection groove 54. After the dust collector 5 is powered on and started, the negative pressure generated by the dust collector 5 enters the interior of the dust suction pipe 52 through the through groove 53, and then enters the interior of the dust collector 5 through the connecting pipe 51 for collection, so as to collect the debris and impurities cleaned from the corrugated pipe. Through this step, the dust collector 5 can effectively collect the cleaned debris in time, effectively reduce the problem of debris scattering and flying in the working area, and timely collection can effectively reduce the residence time of debris in the working area, effectively keep the working area clean, make the cleaning work more simple and fast, and reduce the difficulty of subsequent cleaning work caused by debris accumulation.

[0027] As Figure 1 after Figure 4 As shown, a plurality of fixing holes 6 are formed at the top of the base 1; each group of the fixing holes 6 is arranged between two fixing clamps 16; a limiting block 61 is installed in the middle of each group of the fixing holes 6; during operation, according to the diameter of the corrugated pipe, the limiting block 61 is placed in one of the fixing holes 6. When the output end of the electric push rod 11 pushes the push plate 12, the push plate 12 contacts the limiting block 61 during the movement process. The push plate 12 is limited by the limiting block 61 to precisely clamp the corrugated pipe with the fixing clamp 16. Through this step, the push plate 12 is limited by adjusting the position of the limiting block 61, so that the electric push rod 11 and the push plate 12 will not have redundant movement during the fixing process of the corrugated pipe, effectively limiting the precise range of the electric push rod 11 pushing the push plate 12, and being able to precisely control the stability and predictability during the processing process.

[0028] As Figure 1 As shown, a sponge block 7 is fixedly connected to the middle of one group of the rollers 34; the sponge block 7 is fixedly connected to the side far from the brush bristles 4; during operation, when the corrugated pipe passes between the two rollers 34 and is fixed by the fixing clamp 16, the flexible material of the sponge block 7 contacts the surface of the corrugated pipe. Through this step, the flexible material of the sponge block 7 contacts the surface of the corrugated pipe, which can effectively increase the friction between the roller 34 and the corrugated pipe and can prevent the corrugated pipe from being damaged during the continuous processing and moving process.

[0029] The working principle and use process of the utility model are as follows: a plurality of electric push rods 11 are powered on and turned on. When the bellows is continuously processed and moved by conveying, it first passes between the two groups of push plates 12. After the bellows is moved to the designated position for processing, the output ends of the two groups of electric push rods 11 are controlled to stretch toward the bellows, so that the output ends of the electric push rods 11 move the push plates 12 toward the middle of the bellows, and contact the two sides of the bellows through a plurality of opposite fixed splints 16. The fixed splints 16 are arranged in an arc shape to fit the surface of the bellows. Under the continuous push of the electric push rods 11, the spring 14 is subjected to pressure to produce elastic contraction into the groove 13. At the same time, the end of the buffer head 15 enters the groove 13 and presses against the end of the groove 13 to limit the position. The contact pressure of the fixed splint 16 on the bellows is adjusted by the spring 14. , the bellows is clamped and fixed by multiple fixing clamps 16, and then the bellows is processed. When the fixing clamps 16 clamp and fix the bellows, the clamping pad 23 enters the concave position corresponding to the bellows. When the clamping pad 23 contacts the protruding position of the bellows, the clamping pad 23 slides along the protruding part of the bellows through the sliding plate 22 in the sliding groove 2 and the limiting groove 21, so as to fine-tune the clamping pad 23 in the middle position of the limiting groove 21. When the bellows is in the process of continuous movement and processing, when the bellows deviates from the center position, the end of the bellows is guided by two support rods 33 at one end, so that the bellows enters between the two rollers 34, and after the middle of the bellows contacts the two rollers 34, the two rollers 34 are squeezed to both sides, and the rollers 34 are pressed to the sides. 4 moves to one side so that the sleeve 31 rotates in the middle of the fixed rod 3, and at the same time, the bottom end of the support rod 33 drives the slider 36 to slide in the middle of the moving groove 35. When the slider 36 slides, the elastic rope 37 is subjected to tension to produce elastic stretching, and the end of the bellows moves between the two rollers 34 at the other end of the top of the base 1. When the bellows moves, the rollers 34 on both sides rotate in the middle of the support rod 33 at the same time, and the two rollers 34 are used to keep the center position of the bellows during the continuous processing and movement. When the bellows processing is completed, the roller 34 is reset by the elastic contraction of the elastic rope 37. When the bellows is fixed and processed, it passes between the two rollers 34 at one end, and multiple bristles 4 contact the surface of the bellows. When the roller 34 rotates, the multiple bristles 4 are used to push the bellows The surface of the bellows is cleaned, and the collecting groove 54 is set as an inclined surface near the roller 34. When multiple bristles 4 clean the surface of the bellows, the debris and impurities on the surface of the bellows enter the middle of the collecting groove 54 along one side of the collecting groove 54, and the vacuum cleaner 5 is powered on and turned on. The negative pressure generated by the vacuum cleaner 5 enters the inside of the dust suction pipe 52 through the through groove 53, and then enters the inside of the vacuum cleaner 5 through the connecting pipe 51 for collection, so that the debris and impurities cleaned by the bellows are collected. According to the diameter of the bellows, the limit block 61 is placed in one of the fixing holes 6. When the output end of the electric push rod 11 pushes the push plate 12, the push plate 12 contacts the limit block 61 during the movement, and the push plate 12 is limited by the limit block 61, so that the fixed clamping plate 16 is controlled to be accurately clamped with the bellows.When the corrugated pipe is fixed by the fixed clamping plate 16 when passing between the two rollers 34, the flexible material of the sponge block 7 contacts the surface of the corrugated pipe.
