Description

Technical Field

[0001] This utility model relates to the technical field of copper tube coiling machines, specifically a coiling machine with a copper tube protection device. Background Technology

[0002] Capillary copper tubes are copper tubes with very small diameters, light weight, good thermal conductivity, and high low-temperature strength. Small-diameter capillary copper tubes are often used to transport pressurized liquids (such as lubrication systems, hydraulic systems, etc.) and as instrument pressure measuring tubes. During the production and processing of capillary copper tubes, a coiling machine is needed to stretch and adjust the capillary copper tubes. The coiling machine is one of the key pieces of equipment in the copper tube production line, and the main dimensions and shapes of the copper tubes are derived from the coiling machine.

[0003] An investigation revealed that a Chinese utility model patent discloses a coil drawing machine for producing capillary copper tubes (publication number: CN213103821U), comprising a base, on which a support plate is provided for mounting a fixed plate, and a mounting plate is fixedly mounted on the fixed plate. A motor is fixedly mounted on the bottom surface of the mounting plate, and the output shaft of the motor is fixedly connected to a rotating plate. The rotating plate is rotatably mounted inside the fixed plate via a bearing. A turntable is mounted on the bottom surface of the rotating plate via a connecting rod, and a receiving roller is mounted on the bottom surface of the turntable. Several horizontal isolation plates are evenly and fixedly installed on the receiving roller, and several receiving grooves are separated on the receiving roller by the isolation plates.

[0004] In the aforementioned patent, although the collection roller is equipped with multiple collection slots during use compared to existing technologies, enabling the simultaneous coiling of multiple copper tubes and greatly improving the working efficiency of the coiling machine, and the collection roller is easy to disassemble and replace, effectively reducing the difficulty of the worker's work, it is impossible to clean the impurities attached to the copper tubes during the coiling process. As a result, when the copper tubes are tangled together, the impurities attached to their surface will cause some of the copper tubes to have pits and bends, thus affecting the lifespan of the copper tubes. Furthermore, after long-term cleaning of the copper tubes, a lot of impurities will also be attached to the cleaning structure, so that the impurities attached to the cleaning structure need to be cleaned manually, which increases the tediousness.

[0005] Therefore, this utility model provides a coil drawing machine with a copper tube protection device to solve the above problems. Utility Model Content

[0016] (III) Beneficial Effects

[0017] This invention, through the design of a cleaning brush, telescopic rod, spring, and cam, removes surface impurities from the copper tube after it passes through the cleaning brush. The motor drives the cam to rotate, repeatedly squeezing the cleaning brush, which then moves and resets due to the elastic force of the telescopic rod and spring. This causes impurities attached to the cleaning brush to be shaken off to a certain extent. This device allows the coiling machine to clean impurities attached to the copper tube, preventing the copper tube from becoming tangled and damaged by impurities, thus reducing the probability of the copper tube's lifespan being affected. Furthermore, it can simultaneously clean impurities attached to the cleaning brush, eliminating the need for manual, periodic cleaning of the brush and effectively reducing tediousness.

[0025] 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.

[0026] This utility model provides a coil drawing machine with a copper tube protection device, such as Figure 1-5As shown, the disc puller includes a disc puller body 1. The disc puller body 1 has an opening 2 inside for impurities to fall down. A telescopic rod 3 is fixedly connected to the inner wall of the disc puller body 1 inside the opening 2. A cleaning brush 4 is fixedly connected to the movable end of the telescopic rod 3. A spring 5 is fixedly connected to the inner wall of the disc puller body 1 inside the opening 2. The end of the spring 5 near the cleaning brush 4 is fixedly connected to the outer wall of the cleaning brush 4. The telescopic rod 3 is inserted through the inner ring of the spring 5. A cam 6 is rotatably connected to the inner wall of the disc puller body 1 inside the opening 2. A motor 7 is provided inside the disc puller body 1 to drive the cam 6 to rotate.

[0027] Specifically, when it is necessary to clean the impurities attached to the copper pipe to indirectly protect it, the copper pipe can pass through the cleaning brush 4 during the coiling process. After passing through the cleaning brush 4, the impurities attached to the surface of the copper pipe can be cleaned by the cleaning brush 4, preventing the impurities attached to the copper pipe from causing pits and bends in the copper pipe during subsequent winding. Making the copper pipe smoother will improve the life and performance of the copper pipe, thus indirectly providing protection for the copper pipe. In addition, the impurities that are cleaned and dropped can fall down through the opening 2 for easy collection and processing later.

[0028] Simultaneously, motor 7 is started, which drives cam 6 to rotate via the output shaft. Each time the convex surface of cam 6 rotates and contacts cleaning brush 4, it repeatedly squeezes cleaning brush 4. This repeated squeezing and releasing of cam 6 allows the elastic force of telescopic rod 3 and spring 5 to achieve a cyclical movement and reset of cleaning brush 4, creating a vibration effect that shakes off internal impurities. This reduces the amount of impurities on the cleaning brush 4, preventing excessive impurities from affecting its cleaning performance and necessitating manual cleaning. Therefore, when cleaning brush 4 has a self-cleaning function, it reduces manual labor, saving time and effort.

[0029] Furthermore, the telescopic rod 3's telescopic nature allows the cleaning brush 4 to move normally after being squeezed by the cam 6. More importantly, it provides a stable support connection point for the cleaning brush 4, preventing instability caused by the cleaning brush 4 relying solely on the support connection of the spring 5. It also prevents the spring 5 from bending due to insufficient support when the weight of the cleaning brush 4 is slightly too large. This ensures the stability of the placement of the cleaning brush 4 and also provides life protection for the spring 5.

[0030] The bottom of the main body 1 of the pulverizing machine is fixedly connected to a box 8, and the box 8 corresponds to the position of the opening 2.

[0031] The inner wall of the main body 1 of the disc puller is rotatably connected to the opening 2 with a sector tooth 10, and a transmission belt 11 is connected between the sector tooth 10 and the cam 6.

[0032] A guide block 12 is provided outside the sector tooth 10, and a plurality of teeth 13 that mesh with the sector tooth 10 are fixedly connected to the inner wall of the guide block 12.

[0033] A cleaning block 14 is fixedly connected to the bottom of the guide block 12, and the cleaning block 14 is located at the bottom of the inner wall of the box 8.

[0034] The bottom of the box 8 is provided with a through hole 9 for the discharge of impurities, and the top of the main body 1 of the pulverizing machine is fixedly connected with a shield 16 around the opening 2.

[0035] Specifically, when the copper tube is cleaned by the cleaning brush 4, the impurities attached to its surface will fall downward into the box 8, making it easier to handle the impurities when they are concentrated in the box 8. This also prevents the impurities from falling to the ground and requiring manual cleaning later. At the same time, during the rotation of the cam 6, the transmission belt 11 that is in cooperation with the cam 6 can drive the sector teeth 10 to rotate synchronously.

[0036] When the sector tooth 10 rotates, the multiple teeth 13 meshing with the sector tooth 10 can drive the guide block 12 to move back and forth, causing the guide block 12 to drive the cleaning block 14 to move back and forth, pushing the impurities concentrated in the box 8 towards the through hole 9. When the impurities move to the through hole 9, they can be discharged outward through the through hole 9, thereby achieving the purpose of processing the impurities in the box 8 and preventing the impurities from accumulating too much due to the inconvenience of cleaning in the box 8. Moreover, the processing does not require manual intervention. It is only necessary to place the receiving item under the through hole 9 to receive the discharged impurities.

[0037] This allows for automated cleaning of copper tubes and subsequent impurity treatment, reducing manual labor while making the cleaning process simple and quick. The shielding area provided by the shielding cover 16 ensures that when the cleaning brush 4 is vibrating, the impurities shaken off will not fall onto the coiling machine body 1, preventing some impurities from falling onto the coiling machine body 1 and requiring manual cleaning. This ensures that all the shaken-off impurities can be concentrated in the box 8 for processing.

[0038] The outer wall of the guide block 12 is fixedly connected to the limit strip 15, and the limit strip 15 is slidably connected inside the housing 8.

[0039] Specifically, the limiting strip 15 provides a support point for the placement of the guide block 12, preventing it from falling directly if it lacks a support point, thus causing the teeth 13 to separate from the sector teeth 10. As a result, when the sector teeth 10 rotates, the teeth 13 in the guide block 12 can always maintain a meshing state with the sector teeth 10, ensuring that when the sector teeth 10 rotates, the guide block 12 can drive the cleaning block 14 to move back and forth to process impurities. Furthermore, the sliding fit between the limiting strip 15 and the housing 8 also provides the conditions for the guide block 12 to move, preventing motion interference between the limiting strip 15 and the housing 8 that would prevent the guide block 12 from moving.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
