Description

TECHNICAL FIELD

[0001] The present application relates to a kind of essential oil filling production integrated device and its working method. BACKGROUND

[0002] Essential oil products have different soothing, moisturizing effects, and are widely used in cosmetics and medical supplies. Essential oil products are generally packaged and stored in essential oil bottles. Currently, essential oil bottles on the market use an inner plug plus an outer cover packaging form. During production, after the essential oil product is filled into the bottle body of the essential oil bottle, the inner plug is first pressed into the bottle opening of the bottle body, and then the outer cover is sleeved outside the bottle opening to prevent essential oil from leaking out of the bottle opening and improve the sealing performance.

[0003] In the essential oil filling industry, by filling essential oil into the essential oil bottle body, then screwing the essential oil bottle nozzle (the essential oil bottle nozzle is composed of a spray cap and a straw connected to the spray cap, and when in use, the nozzle is screwed on the essential oil bottle mouth, and by pressing the spray cap, the essential oil can be sprayed out through the straw), and finally covering the essential oil bottle nozzle with a cover, the finished assembled essential oil can be packaged and then shipped. Traditional essential oil production generally uses manual filling and manual capping, which is time-consuming, labor-intensive and low in efficiency. Some existing essential oil production lines have the following problems: 1. Some essential oil production lines use filling equipment for filling, but the capping work is still mainly manual. After the essential oil product is filled into the essential oil bottle by the filling equipment, the filled essential oil bottle is manually capped. This manual capping method has the problem of low efficiency, which affects the overall production efficiency of essential oil filling and capping. At present, some automatic capping devices are also in use, but these automatic capping devices still mostly need manual operation to place the covers vertically on the capping station, or manually place the covers vertically on different conveying tracks one by one, and then convey the vertically placed covers to the capping devices through different conveying tracks. This manual placement of covers is not convenient enough, reduces the work efficiency of the capping operation, and is not conducive to continuous production; 2. In the process of factory batch production, the nozzle is conveyed by a track, and a lifting block at the end of the track is used to temporarily block the nozzle; when the clamp sends the first nozzle, the block is lowered so that the first nozzle is sent out, and then the block is quickly raised to block the second nozzle; when the clamp sends the second nozzle, the block is lowered so that the second nozzle is sent out, and then the block is quickly raised to block the third nozzle, and so on. In the prior art, the lifting of the block needs to be controlled by a cylinder or a motor, which not only has a complex structure, but also is not designed reasonably. The cylinder or motor is easily damaged when the operation is frequent, and the current device cannot well realize the assembly of the essential oil bottle nozzle and the bottle body; for example, the currently searched Chinese patent "A composite sealing ball essential oil bottle rapid oil filling device" (publication number CN210764252U) includes an auxiliary frame body, a connecting sleeve, an essential oil bottle body, an auxiliary limiting block, and a syringe. The inside of the auxiliary frame body is inserted with a connecting sleeve, the side away from the essential oil bottle body of the connecting sleeve is connected with a handle, the front inside of the connecting sleeve is provided with a placing cavity, and the inside of the placing cavity is connected with a positioning pin. The right side of the connecting sleeve is fixed with a oil filling pipe, the inside of the oil filling pipe is inserted with a syringe, the inner wall of the oil filling pipe is connected with a first fixed block on the left and right sides, and the side away from the oil filling pipe of the first fixed block is provided with a limiting sliding groove; the auxiliary limiting block can effectively increase the stability during oil filling, and the device is provided with a one-way valve, which can stop the flow of essential oil in time after the essential oil is injected, avoiding waste caused by essential oil overflow, but the device cannot complete the conveying of the essential oil bottle nozzle and the screwing of the essential oil bottle nozzle on the bottle body.3. Existing essential oil filling equipment requires the conveyor line to stop for filling when the essential oil bottles are transported to the filling station. After filling is completed, the conveyor line is restarted to send the filled essential oil bottles away and simultaneously send in empty bottles. This results in low work efficiency and the conveyor belt needs to be started and stopped frequently. The automatic essential oil filling equipment disclosed in Chinese Patent CN207861856U is an existing device with the above problems. Summary of the Invention

[0054] In the embodiment, the essential oil bottle nozzle arrangement and conveying device comprises a vibrating disc AE1, a plurality of air nozzles E3 for blowing air towards the nozzle E2 are distributed along the track of the track of the top layer of the vibrating disc A, a spiral channel E5 is connected to the discharge port E4 of the layer of the track, the spiral channel is spirally wound on the outer circumferential portion of the vibrating disc A from top to bottom, the spiral channel is gradually twisted by 180° along the direction from the top inlet E6 to the bottom outlet E7 thereof, and the nozzle is turned over.

[0055] The air blowing directions of the air nozzles are all inclined towards the outside of the track along the moving direction of the nozzle.Figure 1 In fact, the air nozzle has several air nozzles.

[0056] The spiral channel is composed of several fixed frames E8 and several spiral strips E9.

[0057] The fixed frame includes a fixed sheet, and a "convex" shaped nozzle delivery gap E10 is formed on the fixed sheet.

[0062] By distributing several air nozzles used for blowing air towards the nozzle along the track trajectory on the side of the top track of the vibrating disc A, when the nozzles abut each other and pass through the track one by one, the inner thread hole of the nozzle used to be screwed on the bottle mouth is aligned and blown by the air nozzle. Under the thrust of the gas, the nozzle has a certain probability of turning up 90° vertically, that is, the nozzle cap E11 is heavier downward, the suction pipe D2 is upward, the nozzle center of gravity is low, and the nozzle is not easy to be tilted after being vertically erected. Although the probability of the nozzle turning up 90° vertically is not 100%, but since the number of nozzles on the vibrating disc A is large, and the blowing air pressure can be adjusted to improve the success rate of the nozzle turning up 90° vertically, the number of nozzles successfully turning up 90° vertically can meet the production requirements.

[0063] The nozzle turned up 90° vertically enters the top inlet of the spiral channel from the outlet of the track. Under the action of the spiral conveying and gradually twisting 180° of the spiral channel, the nozzle gradually turns over until it finally turns over 180°, that is, the nozzle cap is upward, the suction pipe is downward, and then the nozzle is conveyed downward to the next process from the bottom outlet of the spiral channel. The device can realize the arrangement and feeding of the essential oil bottle nozzle, and the feeding efficiency is high.
