Description

Technical Field

[0001] This utility model belongs to the technical field of PET cosmetic bottle production equipment, and in particular relates to a deburring device for PET cosmetic bottle production. Background Technology

[0002] For deburring PET cosmetic bottles, a hot air gun can be used. Set the temperature to 180℃-220℃ and quickly sweep it across the edge of the PET cosmetic bottle. The burrs will shrink and fall off automatically due to the heat. Maintain a distance of 8-10cm between the gun nozzle and the workpiece during operation, and each heating session should not exceed 3 seconds. However, ensure proper ventilation in the workshop.

[0003] Because the hot air gun only runs for 3 seconds and then stops, the instantaneous current when it is turned on is very large, wasting electrical energy, and the temperature cannot be raised. After running for 3 seconds, it blows dry, causing a large amount of heat to be lost, which also wastes electrical energy. This results in the relatively low practicality of conventional heating deburring equipment.

[0004] Therefore, we propose a deburring device for PET cosmetic bottle production to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem of low practicality of conventional heating deburring equipment, and to propose a deburring device for PET cosmetic bottle production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A deburring device for PET cosmetic bottle production includes a servo geared motor and a hot air blower. A return air duct is externally connected to the hot air blower, and the internal space of the return air duct communicates with the internal space of the hot air blower's duct. A valve plate is provided at the front of the return air duct. A first flange is fixedly connected to the rotor of the servo geared motor, and the valve plate is screwed onto the first flange. An external power source drives the hot air blower to blow hot air into the return air duct. The valve plate blocks the airflow in front of the return air duct, causing the obstructed airflow to flow back to the air inlet of the hot air blower, creating a circulation of hot air. This prevents the hot air blower from drawing in large amounts of ordinary outside air, reducing heat energy waste. The servo geared motor is adjusted to rotate once every four seconds, ensuring the return air duct opening is unobstructed for three seconds. The servo geared motor only needs to run once when deburring is required. By recovering the blocked hot air through the return air duct, heat energy utilization is improved, and energy waste is reduced.

[0007] Preferably, a reinforcing sleeve is fixedly connected to the lower part of the servo geared motor, and the reinforcing sleeve is fixedly fitted outside the return air duct. The reinforcing sleeve increases the firmness of the connection between the servo geared motor and the return air duct.

[0008] Preferably, the return air duct includes a return pipe, one end of which is fixedly connected to a guide pipe, and the other end of which is fixedly connected to a gas collecting hood. The return pipe communicates with the internal spaces of both the guide pipe and the gas collecting hood. The gas collecting hood is fixedly connected to the air intake of the hot air blower, and the guide pipe is fixedly installed at the air outlet of the hot air blower. When the guide pipe is shielded by the valve plate, the obstructed gas flows back into the gas collecting hood through the return air duct, causing the hot air blower to draw in the gas from the gas collecting hood, thus circulating the hot air and facilitating heat energy recovery.

[0009] Preferably, the first flange includes a fixing seat, which is fixedly connected to the output shaft of the servo geared motor. A flange body is fixedly connected to the front end of the fixing seat, and a threaded hole is provided on the flange body. The screws are removed, the valve plate is taken off, and a new valve plate is installed, facilitating the replacement of damaged valve plates.

[0010] Preferably, the valve plate includes a rotating ring, with a baffle fixedly connected inside the rotating ring, and a second flange fixedly connected to the upper end of the baffle. Screws are passed through the second flange and tightened onto the flange body, using the rotating ring to increase rotational stability.

[0011] Preferably, the valve plate further includes a counterweight, which is fixedly connected to the outside of the rotating ring. The counterweight balances the centrifugal force of the rotating baffle, further increasing the stability of the valve plate's rotation.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. Use an external power supply to drive the hot air blower to blow hot air into the return air duct. Use a valve plate to block the return air duct, so that the obstructed airflow flows back to the air inlet of the hot air blower through the return air duct, so that the hot air forms a circulation and avoids the hot air blower from sucking in a large amount of ordinary air from the outside, thus reducing heat energy waste. Adjust the servo geared motor to rotate once every four seconds, and keep the return air duct opening in an unobstructed state for 3 seconds. When deburring is required, run the servo geared motor once. By recovering the blocked hot air through the return air duct, the heat energy utilization rate is improved and energy waste is reduced.

[0013] 2. When the air duct is shielded by the valve plate, the obstructed gas flows back into the gas collection hood through the return air duct, causing the hot air fan to draw in the gas in the gas collection hood, thus circulating the hot air and facilitating heat energy recovery.

[0016] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.

[0017] like Figure 1 As shown, a deburring device for PET cosmetic bottle production includes a servo geared motor 1 and a hot air blower 6. A return air duct 2 is fixedly connected to the outside of the hot air blower 6. The internal space of the return air duct 2 communicates with the internal space of the hot air blower 6. A valve plate 4 is provided at the front of the return air duct 2. A first flange 3 is fixedly connected to the rotor of the servo geared motor 1, and the valve plate 4 is installed on the first flange 3 with screws. The hot air blower 6 is a variable frequency heater. Using an external power supply, the hot air blower 6 blows hot air into the return air duct 2. The valve plate 4 blocks the airflow in front of the return air duct 2, causing the obstructed airflow to flow back to the air inlet of the hot air blower 6, thus creating a circulation of hot air. This prevents the hot air blower 6 from drawing in large amounts of ordinary outside air, reducing heat energy waste. The servo geared motor 1 is adjusted to rotate once every four seconds, keeping the return air duct 2 open for three seconds. The servo geared motor 1 is run once when deburring is required.

[0018] like Figure 1 As shown, a reinforcing sleeve 5 is fixedly connected to the lower part of the servo geared motor 1, and the reinforcing sleeve 5 is fixedly fitted outside the return air duct 2. The reinforcing sleeve 5 is used to increase the firmness of the connection between the servo geared motor 1 and the return air duct 2.

[0019] like Figure 1 and 2 As shown, the return air duct 2 includes a return pipe 21. One end of the return pipe 21 is fixedly connected to a guide pipe 22, and the other end is fixedly connected to a gas collection hood 23. The return pipe 21 communicates with the internal spaces of both the guide pipe 22 and the gas collection hood 23. The gas collection hood 23 is fixedly connected to the air intake of the hot air blower 6, and the guide pipe 22 is fixedly installed at the air outlet of the hot air blower 6. When the guide pipe 22 is shielded by the valve plate 4, the obstructed gas flows back into the gas collection hood 23 through the return air duct 2, causing the hot air blower 6 to draw in the gas from the gas collection hood 23, thus circulating the hot air.

[0020] like Figure 1 and 3As shown, the first flange 3 includes a fixing seat 31, which is fixedly connected to the output shaft of the servo geared motor 1. A flange body 32 is fixedly connected to the front end of the fixing seat 31, and a threaded hole is provided on the flange body 32. Remove the screws, remove the valve plate 4, and replace it with a new valve plate 4.

[0021] like Figure 1 , 3 As shown in Figure 4, the valve plate 4 includes a rotating ring 41, with a baffle 43 fixedly connected inside the rotating ring 41, and a second flange 42 fixedly connected to the upper end of the baffle 43. Screws are passed through the second flange 42 and tightened onto the flange body 32, using the rotating ring 41 to increase rotational stability.

[0022] like Figure 1 and 4 As shown, the valve plate 4 also includes a counterweight 44, which is fixedly connected to the outside of the rotating ring 41. The counterweight 44 is used to balance the centrifugal force of the rotating baffle 43, further increasing the stability of the rotation of the valve plate 4.

[0023] Working principle: The hot air blower 6 is driven by an external power supply to blow hot air into the return air duct 2. The valve plate 4 blocks the airflow in front of the return air duct 2, so that the blocked airflow flows back to the air inlet of the hot air blower 6 through the return air duct 2, so that the hot air forms a circulation and avoids the hot air blower 6 from sucking in a large amount of ordinary air from the outside, thus reducing the waste of heat energy. The servo reduction motor 1 is adjusted to rotate once every four seconds, so that the opening of the return air duct 2 is not blocked for 3 seconds. When it is necessary to remove burrs, the servo reduction motor 1 can be run once.
