Description

Technical Field

[0001] This utility model relates to the technical field of feeding mechanisms, specifically a feeding mechanism for processing air conditioning condenser tubes. Background Technology

[0002] Air conditioner condensate pipes (more accurately called air conditioner condensate drain pipes) are pipes in air conditioning systems specifically designed to remove condensate generated during cooling operation. They collect water droplets condensed on the surface of the heat exchanger of the indoor unit (such as a fan coil unit) or in the condensate pan and drain them outdoors or into the drainage system.

[0003] The processing of air conditioning condenser pipes includes a corresponding feeding process. Existing examples include a plastic pipe processing feeding device with patent publication number CN209381187U. This device uses a dispensing fan to directly draw various raw materials into a mixing drum. A stirring motor, rotating rod, and stirring bar are used to stir the raw materials, ensuring uniform mixing. A hydraulic cylinder controls the left-right movement of a sealing plate, thereby controlling the output of raw materials. A monitoring window visually detects the content and uniformity of the raw materials in the mixing drum. This device eliminates the need for manual material addition; it mixes the raw materials after adding them, reducing workload and improving efficiency.

[0004] However, since this device relies on the weight of the mixture to flow downwards, its high viscosity and small internal and external pressure difference lead to poor discharge and low reliability. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a feeding mechanism for air conditioning condenser tube processing, which is equipped with a screw-mounted piston moving mechanism driven by a motor, enabling positive and negative pressure transfer of raw materials for feeding, smoother discharge, higher precision, and improved practicality.

[0007] Preferably, the connecting mechanism includes a connecting frame, a rail, a sliding frame, a tightening sleeve, a tightening screw, and a tightening handle. The right middle part of the raw material barrel is connected to the left side of the connecting frame. The upper and lower sides of the inside of the connecting frame are connected to the upper and lower ends of the rail. The outer wall of the rail is vertically slidably connected to the inner wall of the sliding frame. The right side of the sliding frame is connected to the left middle part of the transfer cylinder. The front middle part of the sliding frame is connected to the inner side of the tightening sleeve. The inner wall of the tightening sleeve is screwed to the outer wall of the tightening screw. The front side of the tightening screw is connected to the rear middle part of the tightening handle.

The bottom end of the internally threaded pipe 7 is connected to the piston 10. The top of the piston 10 is connected to the bottom of a set of sliding sleeves 9 on both sides. The top of the top of the top frame 4 is connected to the top of a set of guide strips 8 on both sides. The outer wall of the guide strips 8 is slidably connected to the inner wall of the sliding sleeves 9 on the same side. The raw material barrel 1 is fixedly supported in the corresponding position by the bracket 12. The raw materials are mixed and stored in the raw material barrel 1. When feeding is required, the forward and reverse motor 5 is run to make the threaded rod 6 rotate. The threaded rod 6 is screwed into the internal threaded tube 7. The piston 10 is slidably constrained by the guide strips 8 and sliding sleeves 9 on both sides, so that the piston 10 slides upward inside the intermediate cylinder 3, so that the intermediate cylinder 3 is under negative pressure. Part of the raw material is introduced into the intermediate cylinder 3 through the input pipe 2. Then the forward and reverse motor 5 is reversed to make the piston 10 move downward and the material inside the intermediate cylinder 3 is discharged through the discharge head 11 for feeding.

[0021] The connecting mechanism includes a connecting frame 13, a rail 14, a sliding frame 15, a tightening sleeve 16, a tightening screw 17, and a tightening handle 18. The right middle part of the raw material barrel 1 is connected to the left side of the connecting frame 13. The upper and lower sides of the inside of the connecting frame 13 are connected to the upper and lower ends of the rail 14. The outer wall of the rail 14 is vertically slidably connected to the inner wall of the sliding frame 15. The right side of the sliding frame 15 is connected to the left middle part of the transfer cylinder 3. The front middle part of the sliding frame 15 is connected to the inner side of the tightening sleeve 16. The inner wall of the tightening sleeve 16 is screwed to the outer wall of the tightening screw 17. The connection is made so that the front side of the tightening screw 17 is connected to the middle of the rear side of the tightening handle 18; the rail 14 can be fixed on the right side of the raw material barrel 1 via the connecting frame 13, and can slide vertically on the outer wall of the rail 14 via the sliding frame 15. It can be connected to the transfer cylinder 3 for lifting and adjustment to meet the needs of use and maintenance at different heights. At any height within the range, the tightening handle 18 can be turned to rotate the tightening screw 17. The tightening screw 17 is screwed into the tightening sleeve 16 and acts inward to tighten the outer position of the rail 14, thereby improving stability.

[0022] It also includes an oil injection nozzle 19, with the upper outer side of the internally threaded tube 7 connected to the inner side of the oil injection nozzle 19; oil can be injected into the inner wall of the internally threaded tube 7 through the oil injection nozzle 19 for convenient lubrication and maintenance.

[0024] It also includes a one-way valve 21. A set of one-way valves 21 is set on the input pipe 2 and the discharge head 11 according to the corresponding input and output directions. The one-way valve 21 can enable one-way flow between the input pipe 2 and the discharge head 11, avoiding backflow and improving reliability.

[0025] It also includes an observation window 22, which is set in the middle of the front side of the raw material barrel 1; through the observation window 22, it is possible to observe from the outside to the inside, which makes it convenient to judge the condition of the raw materials inside and improves convenience.

[0026] In summary, in the use of an air conditioner condenser tube processing and feeding mechanism, the raw material barrel 1 is fixedly supported in the corresponding position by the bracket 12, and the raw materials are mixed and stored in the raw material barrel 1. When feeding is required, the one-way valve 21 allows for one-way flow between the input pipe 2 and the output head 11 to prevent backflow. The forward and reverse motor 5 runs, causing the threaded rod 6 to rotate. The threaded rod 6 is screwed into the internal threaded pipe 7 and is slidably constrained by the guide strips 8 and the sliding sleeve 9 on both sides, causing the piston 10 to slide upward inside the intermediate rotating cylinder 3, creating a negative pressure inside the intermediate rotating cylinder 3. This allows some of the raw materials to be introduced into the intermediate rotating cylinder 3 through the input pipe 2. Then, the forward and reverse motor 5 reverses, causing the piston 10 to move downward, and the material inside the intermediate rotating cylinder 3 is discharged through the output head 11. The discharge is used for feeding materials. The connecting frame 13 can fix the rail 14 on the right side of the raw material barrel 1. The sliding frame 15 slides vertically on the outer wall of the rail 14. It can be connected to the transfer cylinder 3 for height adjustment to meet the needs of different heights for use and maintenance. At any height within the range, the tightening handle 18 can be turned to rotate the tightening screw 17. The tightening screw 17 is screwed into the tightening sleeve 16 and acts inward to tighten the outer position of the rail 14. Oil can be injected into the inner wall of the inner threaded tube 7 through the oil injection nozzle 19 for convenient lubrication and maintenance. After the oil injection cap 20 is installed on the outside of the oil injection nozzle 19, the inside of the oil injection nozzle 19 can be sealed and protected. The observation window 22 allows observation from the outside to the inside, which is convenient for judging the condition of the raw materials inside and improving convenience.
