Description

Technical Field

[0001] This application relates to the field of bottom cover oil spraying technology, specifically a bottom cover oil spraying machine. Background Technology

[0002] Bottom cap spraying machine is an automated device specifically designed for spraying oily or functional coatings onto the bottom or surface of containers such as bottle caps and can caps. It is widely used in the packaging production process of industries such as food and beverage, daily chemicals, and pharmaceuticals. Its core function is to provide bottle caps with rust prevention, anti-slip, decoration, or branding effects through precise spraying technology, while improving production efficiency and coating quality.

[0003] Currently, bottom cap spraying machines typically insert bottle caps into the spraying drum, where they are then sprayed by nozzles on the spraying tube. After spraying, the oil needs to be discharged from the bottom cap. However, oil tends to accumulate on the inner wall of the bottom cap, which can lead to contamination of the surface after discharge or waste of a large amount of residual oil. Utility Model Content

[0004] The purpose of this application is to provide a bottom cap spraying machine that solves the problem mentioned in the background art. Generally, bottom cap spraying machines put bottle caps into the inside of the spraying drum, and then spray the bottom caps with the help of nozzles on the spraying tube. After the bottom caps are sprayed, the oil needs to be discharged, and then the bottom caps are discharged. However, the inner wall of the bottom caps is prone to storing oil, which leads to pollution of the oil residue on the surface of the bottom caps after discharge, or causes a large amount of oil residue on the surface to be wasted.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This application provides a bottom cover spraying machine, including two turntables. An open-ended rotating cylinder is welded to one side of each turntable, and a cylinder door is hinged to the outer wall of the opening of the open-ended rotating cylinder. An open-ended filter cylinder is welded to the inner wall of each turntable. Positioning plates are welded to the outer walls on both sides of the opening of the open-ended filter cylinder, and the two positioning plates are fixedly connected to the inner wall of the open-ended rotating cylinder. The opening of the open-ended filter cylinder corresponds to the opening of the open-ended rotating cylinder. The positioning filter plates are fixedly connected to the inside of the open-ended rotating cylinder. An oil storage tube is rotatably installed on the inner wall of one of the turntables, and multiple sets of nozzles are installed on the outer wall of the oil storage tube. The oil storage tube passes through the other turntable. An oil drain pipe is installed on the outer wall of one of the turntables, and a valve is installed on the outer wall of the oil drain pipe. A drive mechanism for rotating the open-ended rotating cylinder is provided on one side of the open-ended rotating cylinder, and a receiving mechanism is provided below the open-ended rotating cylinder.

[0007] By adopting the above technical solution and setting a double-layer structure with an open filter cartridge and an open rotating drum, the oil can flow out quickly through the filter holes of the open filter cartridge to the open rotating drum and be discharged in a concentrated manner after the valve on the oil drain pipe is opened after spraying. The centrifugal force generated by the rotation of the open rotating drum can accelerate the ejection of residual oil from the inner wall of the bottle cap to the outside of the open filter cartridge, effectively reducing the amount of residual oil on the inner wall of the bottle cap. This avoids the pollution of the surrounding environment or subsequent processing steps by residual oil on the surface of the bottle cap after discharge, and also reduces the loss and waste of oil due to residue, improves resource utilization and the cleanliness of the production area, and ensures the stability of spraying quality.

[0008] Optionally, a latch is fixedly installed on the outer wall of the gate and the outer wall of the open rotating cylinder.

[0009] By adopting the above technical solution, the locking mechanism can effectively lock and close the gate and the open rotating drum.

[0010] Optionally, a positioning filter plate is fixedly connected to the outer wall of the open filter cylinder away from the opening, and the positioning filter plate is fixedly connected to the inner wall of the rotating cylinder.

[0011] By adopting the above technical solution, the positioning filter plate can connect the open filter cylinder and the open rotating cylinder, thereby further positioning the open filter cylinder.

[0012] Optionally, the receiving mechanism includes a receiving cylinder, which is positioned directly below the open rotating cylinder.

[0013] By adopting the above technical solution, the bottom cover inside the open rotating drum can be collected by the material receiving cylinder, and the opening of the open rotating drum is in a downward state when discharging material.

[0014] Optionally, a set of brackets is welded to the outer walls on both sides of the receiving cylinder, and a base is welded to the upper end of each set of brackets.

[0015] By adopting the above technical solution, the bracket can be used to position and fix the material cylinder, and the bracket can also fix the base.

[0016] Optionally, a bearing seat is fixedly installed on the upper end of one of the bases, and a connecting cylinder is embedded in the inner wall of the bearing seat. The connecting cylinder is fixedly connected to the corresponding turntable, and the oil storage tube passes through the connecting cylinder. The oil storage tube and the connecting cylinder are rotatably installed.

[0017] By adopting the above technical solution, the base can fix the bearing seat, and the bearing seat can rotate the connecting cylinder. The oil storage tube and the connecting cylinder are rotated by the bearing, which makes it convenient for the oil storage tube not to rotate when the open rotating cylinder rotates.

[0018] Optionally, the drive mechanism includes a stepper motor mounted on the outer wall of another base, with the output shaft of the stepper motor fixedly mounted to the corresponding turntable.

[0019] By adopting the above technical solution, the base can fix the stepper motor, and the stepper motor can drive the turntable to rotate.

[0020] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0021] The technical solution of this application adopts a double-layer structure with an open filter cartridge and an open rotating drum. After spraying, the valve on the oil drain pipe is opened, and the oil can flow out quickly through the filter holes of the open filter cartridge to the open rotating drum and be discharged in a concentrated manner. The centrifugal force generated by the rotation of the open rotating drum can accelerate the ejection of residual oil from the inner wall of the bottle cap to the outside of the open filter cartridge, effectively reducing the amount of residual oil on the inner wall of the bottle cap. This avoids the pollution of the surrounding environment or subsequent processing steps by residual oil on the surface of the bottle cap after discharge, and also reduces the loss and waste of oil due to residue, improves resource utilization and the cleanliness of the production area, and ensures the stability of spraying quality.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-4 This application provides a technical solution: a bottom cover oil spraying machine, including two turntables 1, an open rotating cylinder 2 welded to one side of the two turntables 1 facing each other, a cylinder door 3 hinged to the outer wall of the opening of the open rotating cylinder 2, an open filter cylinder 17 welded to the inner wall of the two turntables 1, positioning plates 4 welded to the outer walls on both sides of the opening of the open filter cylinder 17, the two positioning plates 4 are fixedly connected to the inner wall of the open rotating cylinder 2, the opening of the open filter cylinder 17 corresponds to the opening of the open rotating cylinder 2, the positioning filter plate 5 is fixedly connected to the inside of the open rotating cylinder 2, an oil storage tube 6 is rotatably installed on the inner wall of one of the turntables 1, multiple sets of nozzles 7 are installed on the outer wall of the oil storage tube 6, the oil storage tube 6 passes through the other turntable 1, an oil drain pipe 14 is installed on the outer wall of one of the turntables 1, a valve 15 is installed on the outer wall of the oil drain pipe 14, a drive mechanism for driving the rotation of the open rotating cylinder 2 is provided on one side, and a receiving mechanism is provided below the open rotating cylinder 2;

[0030] In the technical solution of this application, by setting a double-layer structure of open filter cylinder 17 and open rotating cylinder 2, after spraying, the valve 15 on the oil drain pipe 14 is opened, and the oil can flow out quickly through the filter holes of the open filter cylinder 17 to the open rotating cylinder 2 and be discharged in a concentrated manner. The centrifugal force generated by the rotation of the open rotating cylinder 2 can accelerate the discharge of residual oil on the inner wall of the bottle cap to the outside of the open filter cylinder 17, effectively reducing the amount of residual oil on the inner wall of the bottle cap, avoiding the pollution of the surrounding environment or subsequent processing steps by residual oil on the surface of the bottle cap after discharge, reducing the loss and waste caused by oil residue, improving resource utilization and the cleanliness of the production area, and ensuring the stability of spraying quality.

[0031] In the technical solution of this application, such as Figure 1 and Figure 3As shown, the receiving mechanism includes a receiving cylinder 13, which is located directly below the open rotating cylinder 2. The receiving cylinder 13 collects the material from the bottom cover inside the open rotating cylinder 2. During material feeding, the opening of the open rotating cylinder 2 faces downwards. A set of supports 12 is welded to the outer walls on both sides of the receiving cylinder 13. A base 10 is welded to the upper end of each support 12. The supports 12 position and fix the receiving cylinder 13, and also fix the base 10. One of the bases 10 has a bearing seat 9 fixedly installed on its upper end. A connecting cylinder 8 is embedded in the inner wall of the bearing seat 9. The connecting cylinder 8 is fixedly connected to the corresponding turntable 1. The oil storage tube 6 passes through the connecting cylinder 8. The oil storage tube 6 and the connecting cylinder 8 are rotatably installed. The base 10 can fix the bearing seat 9, and the bearing seat 9 can rotatably connect the connecting cylinder 8. The rotatable installation of the oil storage tube 6 and the connecting cylinder 8 is achieved by rotating the bearing, which makes it convenient for the open turntable 2 to rotate while the oil storage tube 6 does not rotate.

[0032] In the technical solution of this application, such as Figure 1 As shown, the drive mechanism includes a stepper motor 11 mounted on the outer wall of another base 10. The output shaft of the stepper motor 11 is fixedly mounted to the corresponding turntable 1. The base 10 can fix the stepper motor 11, and the stepper motor 11 can drive the turntable 1 to rotate.

[0033] In the technical solution of this application, such as Figure 1 and Figure 2 As shown, a latch 16 is fixedly installed on the outer wall of the cylinder door 3 and the outer wall of the open rotating cylinder 2. The latch 16 can lock and close the cylinder door 3 and the open rotating cylinder 2. A positioning filter plate 5 is fixedly connected to the outer wall of the open filter cylinder 17 away from the opening. The positioning filter plate 5 is fixedly connected to the inner wall of the rotating cylinder. The positioning filter plate 5 can connect the open filter cylinder 17 and the open rotating cylinder 2, thereby further positioning the open filter cylinder 17.

[0034] In use, first open the latch 16 to open the cylinder door 3, pour the bottle caps to be sprayed into the open rotating cylinder 2. At this time, the bottle caps fall into the open filter cylinder 17. Then close the cylinder door 3 and lock it. The output shaft of the stepper motor 11 drives the corresponding turntable 1 to rotate, thereby driving the entire open rotating cylinder 2 to rotate. At the same time, the oil storage tube 6 remains stationary because it is rotated and installed with the connecting cylinder 8 through the bearing. Under the centrifugal force generated by the rotation of the open rotating cylinder 2, the bottle caps are evenly distributed in the open filter cylinder 17 and rotate with the cylinder. The port of the oil storage tube 6 can be connected to an external oil supply device, which facilitates the spraying of oil by the nozzle 7. The oil in the oil storage tube 6 is evenly sprayed onto the rotating bottle caps through multiple sets of nozzles 7. After the cap is closed, the entire area is coated. Once the coating is complete, the oil supply is stopped, and the valve 15 on the drain pipe 14 is opened to allow the oil to drain. The oil flows quickly through the filter holes of the open filter cylinder 17 into the open rotating cylinder 2 and is discharged in a concentrated manner. Then, the valve 15 is closed. The centrifugal force generated by the continuous rotation of the open rotating cylinder 2 accelerates the oil remaining on the inner wall of the cap to be thrown out of the filter cylinder, further reducing the residue. This allows the valve 15 to be opened again to discharge the remaining oil. The open rotating cylinder 2 is then adjusted so that the opening faces downwards. Under the action of gravity and centrifugal force, the cap falls into the receiving cylinder 13 directly below for collection, ensuring the coating quality and avoiding oil contamination and waste.
