Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold insulation pipe processing technology, and in particular to a cold insulation pipe end face polishing device. Background Technology
[0002] In industrial fields such as petrochemicals, natural gas storage and transportation, and cryogenic refrigeration, cold insulation pipes are core components for maintaining the low-temperature transport of media. Cold insulation pipes are pipe materials used to prevent heat from entering the interior of cryogenic equipment and pipelines, maintaining the low-temperature state of the internal media. They are mainly composed of rubber and plastic composites and have excellent thermal insulation performance and low-temperature resistance. In cold storage, freezing equipment, and other applications, cold insulation pipes can effectively insulate against external heat, maintain the internal low-temperature environment, and ensure the freshness of food and product quality. Since many chemical substances are sensitive to temperature, cold insulation pipes can prevent the media inside the pipeline from cooling or overheating too quickly, protecting the equipment and ensuring the stable progress of chemical reactions.
[0003] Traditional cold insulation pipe end face polishing equipment requires frequent manual feeding operations during use, which increases the labor intensity of workers. In addition, the equipment cannot be applied to cold insulation pipes of different lengths and sizes, resulting in reduced flexibility. Utility Model Content

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0025] Example 1
[0026] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present utility model. This embodiment provides a polishing device for the end face of a cold insulation pipe, including a base plate 1. A limiting component 2 is fixedly connected to the middle of the upper surface of the base plate 1. A polishing component 3 is provided on one side of the upper surface of the base plate 1 located at the limiting component 2. A feeding component 4 is provided on the other side of the upper surface of the base plate 1 located at the limiting component 2.
[0027] The feeding assembly 4 includes fixed toothed plates 401 symmetrically arranged on the upper surface of the base plate 1, a fixed plate 402 between the two fixed toothed plates 401, a transmission sprocket 404 rotatably arranged on the outer surface of the fixed plate 402, the two transmission sprockets 404 being connected by a transmission chain 405, a cam 406 fixedly connected to the outer surface of the transmission sprocket 404, a rotating plate 407 rotatably connected to the outer surface of the cam 406, an arc-shaped clamping plate 408 fixedly connected to the upper surface of the rotating plate 407, and an inclined feeding plate 409 arranged on the side wall of the fixed toothed plate 401.
[0028] Specifically, a drive motor 403 is inserted into one of the fixed plates 402, and the output end of the drive motor 403 is fixedly connected to one of the transmission sprockets 404.
[0029] Furthermore, through the feeding assembly 4, the drive motor 403 drives the transmission sprocket 404 to rotate. Through the cooperation of the transmission chain 405 and the transmission sprocket 404, the two cams 406 rotate synchronously, thereby driving the rotating plate 407 to rotate, which in turn drives the arc-shaped clamping plate 408 to rotate. The arc-shaped clamping plate 408 drives the cold-keeping tube to move forward continuously. Finally, the cold-keeping tube falls into the limiting assembly 2 through the unloading plate 409. The arc-shaped clamping plate 408 is offset from the teeth on the fixed toothed plate 401. The arc-shaped clamping plate 408 drives the cold-keeping tube on the fixed toothed plate 401 to move, thereby facilitating subsequent polishing operations, avoiding frequent manual feeding operations, and reducing the labor intensity of workers.
[0030] Example 2
[0031] Reference Figure 1 , Figure 3 and Figure 4 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0032] The limiting component 2 includes a first connecting seat 201 fixedly connected to the upper surface of the base plate 1, a fixed rod 202 fixedly connected between the two first connecting seats 201, a support roller 203 rotatably sleeved on the outer surface of the fixed rod 202, an electric push rod 204 fixedly connected to the lower surface of the base plate 1, a through groove 101 fixedly opened on the upper surface of the base plate 1, a movable block 205 movably arranged in the through groove 101, the output end of the electric push rod 204 connected to the movable block 205, a first auxiliary wheel 206 rotatably arranged on the upper surface of the movable block 205, a fixed seat located between the two fixed rods 202 on the base plate 1, a second auxiliary wheel 207 rotatably arranged on the fixed seat, and the second auxiliary wheel 207 and the first auxiliary wheel 206 are located on the same axis.
[0033] Specifically, a limiting groove 102 is formed on the inner wall of the through groove 101, and a limiting slider is fixedly connected to the side wall of the moving block 205. The moving block 205 is slidably connected to the through groove 101 through the limiting slider and the limiting groove 102. The polishing assembly 3 includes a second connecting seat 3011 fixedly connected to the upper surface of the base plate 1. A threaded rod 301 is rotatably connected between the two second connecting seats 3011. A threaded sleeve is provided on the outer surface of the threaded rod 301. A moving seat 302 is fixedly sleeved on the outer surface of the threaded sleeve. A reduction motor 303 is fixedly connected to the moving seat 302. A crossbar is fixedly connected to the outer surface of the moving seat 302, and a rotating shaft is inserted inside the crossbar. One end of the rotating shaft and the output end of the reduction motor 303 are both fixedly connected to pulleys 304. The two pulleys 304 are connected by a belt 305. The end of the rotating shaft away from the pulleys 304 is fixedly connected to a wire wheel 306. A stepper motor 308 is inserted into one of the second connecting seats 3011. The output end of the stepper motor 308 is fixedly connected to one end of the threaded rod 301. A locking block 307 is fixedly connected to the side wall of the movable seat 302. An L-shaped plate 103 is fixedly connected to the upper surface of the base plate 1. The locking block 307 is engaged with the L-shaped plate 103. The movable seat 302 is slidably connected to the base plate 1 through the locking block 307 and the L-shaped plate 103.
[0034] Furthermore, the cold insulation tube is supported by the limiting component 2 and the support rollers 203 on the fixed rod 202. The height of the first auxiliary wheel 206 is greater than the height of the second auxiliary wheel 207. The first auxiliary wheel 206 provides auxiliary support to the front end of the cold insulation tube, while the second auxiliary wheel 207 provides auxiliary support to the lower outer surface of the cold insulation tube. The first and second auxiliary wheels 206 and 207 ensure good stability during rotation of the cold insulation tube. The moving block 205 is moved by the electric push rod 204, thereby… The cold insulation tube is fixed according to its length. The polishing assembly 3 uses a stepper motor 308 to drive the threaded rod 301 to rotate, so that the threaded sleeve drives the moving seat 302 to move on the threaded rod 301. The L-shaped plate 103 and the locking block 307 cooperate to make the moving seat 302 move on the base plate 1 with good stability. The geared motor 303 uses the cooperation of the pulley 304 and the belt 305 to drive the wire wheel 306 to rotate, thereby polishing the outer surface of the cold insulation tube.
[0035] Working Principle: In operation, the drive motor 403 drives the transmission sprocket 404 to rotate. The transmission chain 405, in conjunction with the transmission sprocket 404, causes the two cams 406 to rotate synchronously, thereby driving the rotating plate 407 to rotate, which in turn drives the arc-shaped clamping plate 408 to rotate. The arc-shaped clamping plate 408 moves the cold-insulating tube forward continuously. The arc-shaped clamping plate 408 is offset from the teeth on the fixed toothed plate 401. The arc-shaped clamping plate 408 moves the cold-insulating tube on the fixed toothed plate 401. Finally, the cold-insulating tube falls between the two fixed rods 202 via the feeding plate 409. The support rollers 203 on the fixed rods 202 support the cold-insulating tube. The electric push rod 204 drives the moving block 205 to move, which in turn moves the first auxiliary wheel 206, thus adjusting the length of the cold-insulating tube. The height of wheel 6 is greater than the height of the second auxiliary wheel 207. The first auxiliary wheel 206 provides auxiliary support for the front end of the cold insulation tube, and the second auxiliary wheel 207 provides auxiliary support for the lower outer surface of the cold insulation tube. The first and second auxiliary wheels 206 limit the movement of the cold insulation tube. The geared motor 303, through the cooperation of pulley 304 and belt 305, drives the wire wheel 306 to rotate. The wire wheel 306 polishes the outer surface of the cold insulation tube. The stepper motor 308 drives the threaded rod 301 to rotate, causing the threaded sleeve to move the movable seat 302 on the threaded rod 301. The cooperation of L-shaped plate 103 and locking block 307 ensures good stability when the movable seat 302 moves on the base plate 1. The movable seat 302 drives the wire wheel 306 to move, thereby polishing the end face of the cold insulation tube and improving the practicality of the device.
