Description

Technical Field

[0001] This invention belongs to the field of aerosol production technology, specifically relating to a buffer conveying mechanism for aerosol production line. Background Technology

[0002] Aerosol cans typically require cleaning and drying of both the inner and outer walls before filling. Existing continuous aerosol production lines are usually set up continuously, and the lack of buffer space during the transfer of cylinders on the conveyor belt often leads to collisions, resulting in defects such as dents and scratches on the cylinders' appearance.

[0003] Because the bottom of gas cylinders typically has a concave structure, the concave dead corners can easily trap residual lubricating oil and metal shavings from the can-making process. Traditional cleaning methods for the cylinder's interior often result in incomplete cleaning of the connection between the cylinder body and the bottom, leaving impurities inside. After filling, these impurities remain suspended in the liquid, causing black spots and flocculent material to appear when the finished product is sprayed. Hard metal particles can also wear down valve sealing rings, leading to slow leakage, pressure loss, and rendering the aerosol product unusable. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention provides a buffer conveying mechanism for aerosol production lines, which can prevent gas cylinders from colliding with each other during conveying and prevent impurities from remaining in the concave corners of the gas cylinders during cleaning.

[0005] The specific technical solution adopted in this invention is as follows:

[0006] A buffer conveying mechanism for an aerosol production line includes multiple mounting seats, multiple socket rods, and two sets of guide rods. The mounting seats are staggered on a conveyor belt, each mounting seat including two spaced-apart clamping plates with a flexible base between them. The socket rods are arranged in a one-to-one correspondence with the mounting seats, with the axial distance between adjacent socket rods greater than the diameter of the gas cylinder. The socket rods swing along the width of the conveyor belt via the flexible base, with adjacent socket rods swinging in opposite directions and both facing outwards from the conveyor belt. The two sets of guide rods are symmetrically arranged parallel to each other above the conveyor belt along its running direction, with the guide rods abutting against the shoulders of the gas cylinders. The guide rods are located on the side of the socket rods closest to the centerline of the conveyor belt width.

[0007] The socket rod is a rod-shaped structure with a hollow cavity inside, and the top of the socket rod is provided with a nozzle connected to the hollow cavity. The aerosol production line is also provided with an inner wall cleaning unit, which is located at the cleaning station. The inner wall cleaning unit includes:

[0008] A cleaning chamber is installed over the cleaning station of the conveyor belt;

[0009] A limiting clamp is provided in the cleaning chamber. The limiting clamp includes an upper clamp and a lower clamp, which are spaced apart. One of the upper clamp and the lower clamp is a brush plate with bristles.

[0010] A jetting assembly is located in the cleaning chamber and is connected to the hollow cavity. The jetting assembly is used to deliver liquid or solid cleaning media into the gas cylinder for cleaning.

[0011] The guide rod is fixedly connected to the cleaning chamber and passes through the cleaning chamber.

[0012] The flexible base is a hemispherical airbag, and the conveyor belt has a notch that communicates with the hollow cavity through the hemispherical airbag; the blowing assembly includes an air source and multiple air pipes.

[0013] Multiple air pipes are located below the conveyor belt and are connected to the air source; the multiple air pipes are arranged in parallel at intervals along the running direction of the conveyor belt, and air holes corresponding to the notches are opened on the air pipes.

[0014] The nozzle is provided with a pin at the top, and the end of the pin abuts against the concave dead corner.

[0015] The nozzle is provided with multiple spray holes, and the multiple spray holes are arranged on the same side.

[0016] The cleaning chamber is also equipped with a hot air drying unit, which includes a hot air drying system and a connecting pipe. The hot air drying system is connected to the hollow cavity through the connecting pipe.

[0017] Both the upper clamping plate and the lower clamping plate have the freedom to move in the vertical direction.

[0018] A flexible cleaning brush is also fixed on the socket rod.

[0019] The beneficial effects of this invention are:

[0020] In this invention, when the gas cylinder is transferred to the conveyor belt, the conveyor belt is equipped with mounting seats and receiving rods, and the axial distance between any two adjacent receiving rods is greater than the diameter of the gas cylinder. Simultaneously, the receiving rods swing along the width of the conveyor belt via the flexible base, thus preventing collisions between the gas cylinders during transport. Since the gas cylinder is inverted on the receiving rods, impurities inside the cylinder will spill out. Upon reaching the cleaning station, the spray assembly is activated, spraying the cleaning medium into the gas cylinder through nozzles. When the cleaning medium is sprayed into the gas cylinder, the cylinder is subjected to a flushing force, causing it to bounce up and down. A limiting clamp holds the gas cylinder in place, and the conveyor belt's forward movement causes the gas cylinder to rotate relative to the limiting clamp, resulting in circumferential rotation. As the gas cylinder rotates, the nozzles flush out the concave dead corners, and the flushed-off processing oil and metal dust are quickly discharged with the cleaning fluid, eliminating blind spots at the bottom of the cylinder and improving the overall uniformity of cleaning.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0029] Specific implementation examples Figures 1 to 6As shown, the present invention is a buffer conveying mechanism for an aerosol production line, comprising multiple mounting seats 11, multiple socket rods 2, and two sets of guide rods 13. The mounting seats 11 are staggered on the conveyor belt 1, and each mounting seat 11 includes two spaced-apart clamping plates, with a flexible base 12 positioned between the two spaced-apart clamping plates.

[0030] Multiple socket rods 2 are arranged one-to-one with the mounting base 11, and the axial distance between any two adjacent socket rods 2 is greater than the diameter of the gas cylinder 100. The socket rods 2 are oscillating on the conveyor belt 1 along the width direction of the conveyor belt 1 via the flexible base 12, and the oscillation directions of any two adjacent socket rods 2 are opposite and both face outwards from the conveyor belt 1.

[0031] Two sets of guide rods 13 are arranged symmetrically in parallel above the conveyor belt 1 along the running direction of the conveyor belt 1. The guide rods 13 abut against the shoulder of the gas cylinder 100. The guide rods 13 are located on the side of the socket rod 2 close to the center line of the width of the conveyor belt 1.

[0032] When the gas cylinder 100 is transferred to the socket rod 2 on the conveyor belt 1, the socket rod 2 swings along the width direction of the conveyor belt 1 due to the setting of the flexible base 12 and the clamping plate. The axial distance between two adjacent socket rods 2 is greater than the diameter of the gas cylinder 100, so as to avoid the gas cylinder 100 colliding with each other during the transportation process.

[0033] The gas cylinder 100 is inserted upside down into the receiving rod 2. The guide rod 13 is arranged on the side of the receiving rod 2 near the center line of the width of the conveyor belt 1 and is positioned above the conveyor belt 1. One shoulder of the gas cylinder 100 rests against the guide rod 13, while the other shoulder is suspended in the air. Due to the shift of the center of gravity of the gas cylinder 100, the gas cylinder 100 tilts and swings on the conveyor belt 1.

[0034] The two sets of guide rods 13 form a figure-eight outward expansion structure, which can complete the posture correction before the gas cylinder 100 enters the cleaning chamber 3. Relying on the lateral pushing of the guide rods 13 and the limiting clamping of the two clamping plates, the gas cylinder 100 can only tilt to the outside of the width of the conveyor belt 1, and the swing direction of the gas cylinders on the adjacent receiving rods 2 is opposite.

[0035] The conveyor belt 1 drives the gas cylinder 100 forward along the guide rod 13. The cylinder shoulder continuously contacts and rubs against the guide rod 13, causing the gas cylinder 100 to rotate circumferentially.

[0036] Based on the above embodiments, the socket rod 2 is a rod-shaped structure with a hollow cavity inside, and the top of the socket rod 2 is provided with a nozzle 22 connected to the hollow cavity. The aerosol production line also includes an inner wall cleaning unit, which is located at the cleaning station. The inner wall cleaning unit includes a cleaning chamber 3, a limiting clamp 4, and a spray assembly. The cleaning chamber 3 covers the cleaning station of the conveyor belt 1. The limiting clamp 4 is located inside the cleaning chamber 3 and includes an upper clamp 41 and a lower clamp 42, which are spaced apart. One of the upper clamp 41 and the lower clamp 42 is a brush plate with bristles. The spray assembly is located inside the cleaning chamber 3 and is connected to the hollow cavity. The spray assembly is used to deliver liquid or solid cleaning media into the gas cylinder 100 for cleaning.

[0037] The guide rod 13 is fixedly connected to the cleaning chamber 3 and passes through the cleaning chamber 3.

[0038] Because the guide rod 13 abuts against the shoulder of the cylinder, the conveyor belt 1 drives the cylinder 100 forward along the direction of the guide rod 13, thus the cylinder 100 undergoes circumferential movement under the action of the guide rod 13. When the cylinder 100 reaches the cleaning station, two sets of symmetrical limiting clamps 4 set in the cleaning chamber 3 limit and clamp the cylinder 100. The upper clamp 41 contacts the bottom of the cylinder 100, and the lower clamp 42 contacts the neck of the cylinder 100. Because the cylinder 100 moves forward under the drive of the conveyor belt 1, the conveyor belt 1 causes the cylinder 100 to rotate relative to the limiting clamps 4 during the forward movement.

[0039] The jet cleaning assembly is activated, spraying the cleaning medium into the gas cylinder 100 through nozzle 22. As the cleaning medium enters the cylinder, it is subjected to a rinsing force, causing it to bounce and rotate. Due to the flexible cleaning brush 21, the cylinder opening is also cleaned as it bounces. The flexible cleaning brush 21 generates relative friction with the inner wall and concave surface of the cylinder bottom, while the nozzle 22 continuously cleans the concave dead corners 101. Processing oil and metal dust that are washed away are quickly discharged with the cleaning fluid, eliminating blind spots at the bottom of the cylinder and improving the overall cleaning uniformity of the gas cylinder 100.

[0040] Optionally, the upper clamping plate 41 is a brush plate with bristles, and the lower clamping plate 42 is a smooth plate. Because the upper clamping plate 41 and the lower clamping plate 42 are of different types, the friction between the gas cylinder 100 and the upper clamping plate 41 and the lower clamping plate 42 is different, which causes the gas cylinder 100 to rotate circumferentially at a differential speed when passing through the clamping space between the upper clamping plate 41 and the lower clamping plate 42.

[0041] The flexible base 12 is a hemispherical airbag, and the conveyor belt 1 has a notch that connects to the hollow cavity through the hemispherical airbag. The blowing assembly includes an air source and multiple air pipes 5. The multiple air pipes 5 are located below the conveyor belt 1 and are connected to the air source. The multiple air pipes 5 are arranged in parallel at intervals along the running direction of the conveyor belt 1, and each air pipe 5 has an air hole 51 corresponding to the notch.

[0042] When the conveyor belt 1 drives the mounting base 11 and the socket rod 2 through the air pipe 5 set below the conveyor belt 1, because the mounting base 11 is set at intervals, when passing through multiple air pipes 5, the gas will intermittently pass through the notch, the flexible base 12, the hollow cavity, and the nozzle 22 and finally enter the gas cylinder 100, thereby blowing the concave dead corner 101 inside the gas cylinder 100, so that the impurities inside the gas cylinder 100 are better flushed down.

[0043] A pin 24 is provided at the top of the nozzle 22, and the end of the pin 24 abuts against the concave dead corner 101. In order to maintain a certain gap between the nozzle 22 and the concave dead corner 101, a pin 24 is provided at the top of the nozzle 22. Since the bottle body and the receiving rod 2 are inclined, and under the action of its own weight, the pin 24 is always abutting against the concave dead corner 101, which facilitates rinsing the concave dead corner 101.

[0044] The nozzle 22 is provided with multiple spray holes 23, which are arranged on the same side. The arrangement of multiple spray holes 23 on the same side ensures that the gas cylinder 100 always receives cleaning force from one side, which, together with the circumferential rotation of the gas cylinder 100, achieves a cleaner and faster rinsing of the gas cylinder 100.

[0045] The cleaning chamber 3 is also equipped with a hot air drying unit, which includes a hot air drying system and a connecting pipe. The hot air drying system is connected to the hollow cavity through the connecting pipe.

[0046] After cleaning, the gas cylinder 100 is dried by a hot air unit. The hot air drying system blows dry hot air into the socket rod 2 through a connecting pipe, and finally blows it into the gas cylinder 100 through the nozzle 22, thus achieving rapid drying of the inner wall of the gas cylinder 100 and avoiding the residue of cleaning medium in the gas cylinder 100.

[0047] Both the upper clamping plate 41 and the lower clamping plate 42 have the freedom to move in the vertical direction.

[0048] Since the dimensions of gas cylinders 100 vary depending on their specifications, their dimensions after tilting will also differ. Therefore, operators can adjust the vertical position and height of the upper clamping plate 41 and the lower clamping plate 42 according to the dimensions of different gas cylinders 100, thereby adjusting the installation distance and clamping limit height of the upper clamping plate 41 and the lower clamping plate 42 to adapt to the positioning and conveying requirements of different models of gas cylinders 100.

[0049] A flexible cleaning brush 21 is installed on the socket rod 2. When the hollow socket rod 2, carrying the flexible cleaning brush 21, extends into the inner cavity of the gas cylinder 100, the gas cylinder 100 will bounce slightly up and down when passing through the gas pipe 5 during transportation. The flexible cleaning brush 21 can clean the mouth of the gas cylinder 100, and at the same time form relative friction with the inner wall and the concave curved surface of the bottom of the gas cylinder 100; relying on the vibration generated by the bouncing of the gas cylinder 100, the loose debris is swept away and discharged.

[0050] The limiting clamp 4 holds the gas cylinder 100, and the conveyor belt 1 moves continuously and works with the guide rod 13 to make the gas cylinder 100 rotate relative to the limiting clamp 4, so as to achieve a comprehensive circumferential cleaning of the inner wall of the gas cylinder 100. During the rotation of the gas cylinder 100, the flexible cleaning brush 21 continuously rubs the inner wall of the gas cylinder 100 and the concave curved surface of the bottom of the cylinder, and the nozzle 22 continuously flushes the concave dead corner 101 of the bottom of the cylinder; the processing oil and metal dust that are flushed off are quickly flowed out with the cleaning fluid, eliminating the blind spots in the cleaning of the bottom of the cylinder and improving the overall cleaning uniformity of the gas cylinder 100.

[0051] The flexible cleaning brush 21 has bristles of different lengths designed at different positions of the socket rod 2 according to the shape of the gas cylinder 100 and the cleaning area, so as to better adapt to the cleaning of the inner wall of the gas cylinder 100.
