Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber drawing machines, in particular to a precise positioning cylinder unloading mechanism for a glass fiber drawing machine. Background Technique

[0002] A glass fiber drawing machine is a mechanical device that rapidly draws molten glass into fiber filaments and winds them into fiber coils according to certain rules.

[0003] At present, there are various types of glass fiber drawing machines on the market. Traditional glass fiber drawing mainly focuses on two-point drawing and three-point drawing, and only two to three rolls of yarn can be drawn at a time. After the drawing is completed, workers need to unload the yarn cylinder and install a new one, resulting in high labor intensity and low cylinder unloading efficiency for workers; some manufacturers equip the drawing machine with special manipulators for cylinder unloading and loading, but the cost of the manipulators is relatively high, and a certain amount of space is required for layout, leading to high production costs. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides a precise positioning cylinder unloading mechanism for a glass fiber drawing machine.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a precise positioning cylinder unloading mechanism for a glass fiber drawing machine, including a horizontally arranged cylinder unloading cylinder and two parallel and spaced cylinder unloading rods. The length direction of the cylinder unloading cylinder is consistent with the length direction of the cylinder unloading rods. A sliding seat is slidably arranged on the cylinder unloading cylinder, and a mounting plate is arranged on the sliding seat. One end of the cylinder unloading rod is rotatably arranged on the mounting plate, the other end extends outward and an arc-shaped rod is fixedly arranged at the end. The arc-shaped openings of the two arc-shaped rods are arranged opposite to each other. Two rotating mechanisms for driving the cylinder unloading rods to rotate are also arranged on the mounting plate, and the rotating mechanisms drive the cylinder unloading rods to rotate to close or separate the two arc-shaped rods.

[0006] By adopting the above technical solutions, the cylinder unloading cylinder, the cylinder unloading rods, and the arc-shaped rods are provided. The cylinder unloading cylinder is used to drive the sliding seat, the mounting plate, and the cylinder unloading rods to move, so that the arc-shaped rods move to the yarn cylinder where cylinder unloading is required. Then, the two arc-shaped rods are driven by the rotating mechanisms to close on the side of the yarn cylinder close to the frame. Then, the cylinder unloading cylinder is used to drive the sliding seat and the cylinder unloading rods to move to push the yarn cylinder forward to the front end of the impeller until it is unloaded. In this way, manual cylinder unloading operations are not required, reducing the labor intensity of workers and improving the cylinder unloading efficiency; at the same time, the cylinder unloading mechanism can be installed using the space of the drawing machine itself, without occupying additional site space, saving production costs.

[0007] Furthermore, both sides of the piston in the cylinder unloading cylinder are connected with air chambers. One ends of the two air chambers far away from the cylinder unloading cylinder are respectively connected to the output ports of a five-way valve I through air pipes, and the intake ports of the two five-way valves I are connected to the air source.

[0008] By adopting the above technical solution, a five-way valve one is connected to both sides of the piston in the cylinder unloading cylinder through air pipes. In this way, when the cylinder unloading cylinder moves to the in-place position, by admitting air simultaneously from both sides, the cylinder unloading cylinder can be ensured to stop moving immediately, effectively controlling the movement precision of the cylinder unloading cylinder and achieving precise positioning.

[0009] Furthermore, a speed control valve is also provided on the air pipe.

[0010] By adopting the above technical solution, a speed control valve is also provided on the air pipe, which can adjust the air intake speed on both sides of the cylinder unloading cylinder, thereby controlling the movement speed of the piston rod of the cylinder unloading cylinder.

[0011] Furthermore, an automatic oil injection system is also included. The automatic oil injection system includes an oil injection cylinder. The two sides of the piston in the oil injection cylinder are respectively an oil storage cavity and an air storage cavity. The oil storage cavity is connected to an oil injection nozzle through an oil inlet pipe for injecting lubricating oil. An oil injection main pipe is provided on the oil inlet pipe. A plurality of oil injection branch pipes are provided on the oil injection main pipe. The outlet of the oil injection branch pipe is connected to the inlet of a two-way valve. The outlet of the two-way valve is connected to the oil-required part of the cylinder unloading rod through a pipeline. The air storage cavity is connected to the output port of a five-way valve two through an air pipe, and the air inlet of the five-way valve two is connected to a gas source.

[0012] By adopting the above technical solution, an oil injection cylinder and a two-way valve are provided for oil injection, which can inject oil into the oil-required part of the cylinder unloading rod regularly and quantitatively. It only needs to regularly check the oil injection cylinder and fill the oil cup. Changing from multi-point oil injection to single-point oil injection greatly reduces the workload of the staff and can increase the service life of the equipment.

[0013] Furthermore, the two control cavities of the two-way valve are respectively connected to the output port of a five-way valve three through air pipes, and the air inlet of the five-way valve three is connected to a gas source.

[0014] By adopting the above technical solution, a five-way valve three is provided to control the on-off of the two-way valve, which is convenient for control.

[0015] In summary, the utility model has the following beneficial effects:

[0016] 1. In this application, by providing a cylinder unloading cylinder, a cylinder unloading rod, and an arc rod, the cylinder unloading cylinder is used to drive the slide seat, the mounting plate, and the cylinder unloading rod to move, so that the arc rod moves to the yarn bobbin where cylinder unloading is required. Then, the rotation mechanism is used to drive the two arc rods to close on the side of the yarn bobbin close to the frame. Then, the cylinder unloading cylinder is used to drive the slide seat and the cylinder unloading rod to move to push the yarn bobbin forward to the front end of the impeller until it is unloaded. In this way, manual cylinder unloading operation is not required, reducing the labor intensity of workers and improving the cylinder unloading efficiency; at the same time, the cylinder unloading mechanism can be installed using the space of the wire drawing machine itself, without occupying additional site space, saving production costs.

[0017] 2. In this application, by controlling a pair of unloading cylinder cylinders through two five-way valves, the unloading cylinder can be accurately stopped at any position, effectively controlling the movement accuracy of the unloading cylinder and achieving precise positioning.

[0018] 3. In this application, by setting an oil injection cylinder, a two-way valve, and a five-way valve three for oil injection, the oil-required parts of the unloading rod can be oil-injected regularly and quantitatively. It only needs to regularly check the oil injection cylinder and fill the oil cup. Changing from multi-point oil injection to single-point oil injection greatly reduces the workload of the staff and can increase the service life of the equipment. Description of the Drawings

[0023] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0024] Such as Figures 1-3As shown in the figure, an accurate positioning and barrel unloading mechanism for a glass fiber drawing machine according to an embodiment of the present application includes a horizontally arranged barrel unloading cylinder 10 and two barrel unloading rods 20 arranged in parallel at intervals. The length direction of the barrel unloading cylinder 10 is the same as the length direction of the barrel unloading rods 20. A sliding seat 11 is slidably arranged on the barrel unloading cylinder 10, and a mounting plate 12 is arranged on the sliding seat 11. One end of the barrel unloading rod 20 is rotatably arranged on the mounting plate 12, the other end extends outwards and an arc-shaped rod 21 is fixedly arranged at the end. The arc-shaped openings of the arc-shaped rods 21 are arranged oppositely. A rotating mechanism 30 for driving the barrel unloading rod 20 to rotate is also arranged on the mounting plate 12. The rotating mechanism 30 drives the barrel unloading rod 20 to rotate so that the two arc-shaped rods 21 are closed or separated. Specifically, the rotating mechanism 30 can be a rotating cylinder. The end of the cylinder body of the rotating cylinder is hinged on the mounting plate 12, and the end of the piston rod is hinged to the inner end of the barrel unloading rod 20.

[0025] When it is necessary to unload the barrel after the yarn drawing is completed, the barrel unloading cylinder 10 drives the sliding seat 11, the mounting plate 12, and the barrel unloading rod 20 to move the arc-shaped rod 21 to the end of the yarn barrel close to the frame. Then the rotating mechanism 30 drives the barrel unloading rod 20 to rotate so that the two arc-shaped rods 21 are closed to the end face of the yarn barrel. Then the barrel unloading cylinder 10 drives the barrel unloading rod 20 to move to push the yarn barrel out from the impeller.

[0026] Specifically, to ensure the accuracy of the movement of the barrel unloading rod 20, air chambers are connected to both sides of the piston in the barrel unloading cylinder 10. The ends of the two air chambers away from the barrel unloading cylinder 10 are respectively connected to the output ports of a five-way valve 13 through air pipes, and the intake ports of the two five-way valves 13 are connected to the air source. Through the setting of the two five-way valves 13, the two sides of the barrel unloading cylinder 10 can either intake air on one side and exhaust air on the other side, or intake air on both sides. That is, when the barrel unloading cylinder 10 is working normally, it intakes air on one side and exhausts air on the other side to ensure the normal movement of the barrel unloading rod 20. When the barrel unloading cylinder 10 drives the barrel unloading rod 20 to move in place and needs to stop, control the five-way valve 13 on the original exhaust side to change the outlet on this side to intake air. In this way, both sides of the barrel unloading cylinder 10 intake air, causing the piston to stop immediately, so that the barrel unloading rod 20 stops moving. In this way, the barrel unloading cylinder 10 can stop accurately at any position, ensuring the positioning accuracy of the barrel unloading rod 20. It more effectively meets the on-site production process and is beneficial to improving production efficiency. Further, a speed regulating valve 14 is also arranged on the air pipe to control the intake and exhaust air speeds of both sides of the barrel unloading cylinder 1021 through speed regulation, so as to control the movement speed of the barrel unloading rod 20.

[0027] This embodiment is also provided with an automatic oil injection system. The automatic oil injection system includes an oil injection cylinder 40. The two chambers on both sides of the piston in the oil injection cylinder 40 are respectively an oil storage chamber and an air storage chamber. The oil storage chamber is connected to an oil injection nozzle 42 through an oil inlet pipe 41 for injecting lubricating oil. An oil injection main pipe 43 is arranged on the oil inlet pipe 41. A number of oil injection branch pipes 44 are arranged on the oil injection main pipe 43. The outlet of the oil injection branch pipe 44 is connected to the inlet of a two-way valve 45. The outlet of the two-way valve 45 is connected to each oil-required part through a pipeline. The air storage chamber is connected to the output port of a five-way valve two 46 through an air pipe. The inlet of the five-way valve two 46 is connected to a gas source. When injecting oil, the five-way valve two 46 controls the outside gas to enter the air chamber, so that the piston in the oil injection cylinder 40 moves towards the oil chamber side, extruding the lubricating oil in the oil chamber. The lubricating oil reaches each oil-required part through the oil inlet pipe 41, the oil injection main pipe 43, the oil injection branch pipes 44, and the two-way valve 45. The oil supply can be controlled by controlling the on-off of the two-way valve 45, so that precise oil injection can be carried out on the oil-required parts. When the lubricating oil in the oil chamber is insufficient, lubricating oil is injected into the oil chamber through the oil injection nozzle 42. Specifically, the two control chambers of the two-way valve 45 are respectively connected to the output port of a five-way valve three 47 through air pipes. The inlet of the five-way valve three 47 is connected to a gas source. The on-off of the two-way valve 45 can be precisely controlled through the five-way valve three 47. Using the oil injection cylinder 40 to inject oil into each oil-required part, the oil injection to each oil-required part can be controlled regularly and quantitatively through a control system, and only the lubricating oil amount in the oil injection cylinder 40 needs to be checked regularly. It changes from the original multi-point oil injection to single-point oil injection, reducing the workload of the staff and increasing the service life of the equipment.

All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
