Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, specifically a surface spraying device for glass cosmetic bottles. Background Technology

[0002] In the production of glass cosmetic bottles, surface coating is a key process to enhance the product's aesthetics and added value. Currently, coating these bottles primarily relies on two methods: manual hand-held coating and the use of fixed automated equipment.

[0003] Manual spraying suffers from drawbacks such as high dependence on operator skill for coating uniformity, high labor intensity, and potential health hazards, making it difficult to maintain consistent product quality. While existing spraying equipment alleviates the burden of manpower to some extent, it cannot meet the needs of flexible production requiring multiple varieties and small batches. This is primarily due to the difficulty in replacing the spray nozzles, and the fact that atomized pigment can easily drift into the bottle from the opening during spraying, contaminating the inner wall and causing product spoilage. This is especially problematic when spraying areas near the bottle opening, such as the shoulder and neck, where traditional sealing relies on specialized film seals, which are inconvenient and lack an effective sealing solution. To address these shortcomings, this invention provides a surface spraying device for glass cosmetic bottles, resolving the aforementioned issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a surface spraying device for glass cosmetic bottles. Driven by an electric push rod, the lifting frame can be flexibly adjusted to change the relative height between the spray nozzle and the bottle body, adapting to cosmetic bottles of different sizes. The motor drives the output shaft and the mounting arm and spray nozzle fixed to it to rotate around the bottle body, achieving automation and standardization of the spraying path. Simultaneously, a rubber stopper is installed at the bottom of the output shaft to tightly fit the bottle opening. Before spraying, the lifting motion automatically seals the bottle opening, forming a physical barrier and completely preventing atomized pigments from entering the bottle and causing contamination. The spray nozzle and rubber stopper are easy to replace and compatible with multiple product models. This structure cleverly integrates rotary drive and bottle opening sealing functions into one compact unit with coordinated actions, meeting various usage requirements.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a surface spraying device for glass cosmetic bottles, comprising a frame and an electric push rod mounted on the frame, wherein a lifting frame is fixedly connected to the output end of the electric push rod, a motor body is fixedly connected to the lifting frame, and an output shaft is provided at the output end of the motor body;

[0006] A mounting arm is fixedly connected to the middle of the output shaft. A spray head for spraying the surface of a glass cosmetic bottle is detachably mounted on the mounting arm. A pumping pipe is provided on the spray head, and the pumping pipe is connected to a pump group for conveying pigment.

[0007] The bottom of the output shaft is rotatably connected to a base, and a rubber stopper for sealing the mouth of a glass cosmetic bottle is detachably installed on the bottom of the base.

[0008] Preferably, a sleeve is fixedly connected to the base, a locking block is fixedly connected to the rubber plug, the locking block is engaged in the sleeve, and a locking component is provided on the base for locking the position of the locking block.

[0009] Preferably, the locking assembly includes:

[0010] The sleeve is fixedly connected to the base;

[0011] A pin is slidably connected inside the sleeve, and the locking assembly is used to lock the block by engaging the pin in the lock hole.

[0015] Preferably, the pin has a handle on its side.

[0016] Preferably, the sleeve has a groove on its side that limits the position of the pin handle.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] This surface coating device for glass cosmetic bottles uses an electric push rod to drive a lifting frame, allowing for flexible adjustment of the relative height between the nozzle and the bottle body to accommodate cosmetic bottles of different sizes. The motor drives the output shaft and the mounting arm and nozzle fixed to it to rotate around the bottle body, automating and standardizing the coating path. Simultaneously, a rubber stopper is installed at the bottom of the output shaft to tightly fit the bottle opening. Before coating, the lifting motion automatically seals the bottle opening, forming a physical barrier and completely preventing atomized pigments from entering the bottle and causing contamination.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This embodiment discloses a surface coating device for glass cosmetic bottles, according to the attached... Figure 1 To be continued Figure 6As shown, the device includes a frame 1 and an electric push rod 11 mounted on the frame 1. The output end of the electric push rod 11 is fixedly connected to a lifting frame 2, and a motor body 3 is fixedly connected to the lifting frame 2. The output end of the motor body 3 is provided with an output shaft 31. A mounting arm 4 is fixedly connected to the middle of the output shaft 31. A spray head 5 for spraying the surface of a glass cosmetic bottle is detachably mounted on the mounting arm 4. A pumping pipe 51 is provided on the spray head 5, and the pumping pipe 51 is connected to a pump group for conveying pigment. A base 6 is rotatably connected to the bottom of the output shaft 31. A rubber stopper 7 for sealing the mouth of the glass cosmetic bottle is detachably mounted on the bottom of the base 6.

[0029] According to the appendix Figure 1 and attached Figure 2 As shown, the lifting frame 2 is slidably connected to the frame 1. The lifting frame 2 is driven to move up and down along the frame 1 by an electric push rod 11, thereby adjusting the height of the spray nozzle 5 and the rubber stopper 7 to accommodate glass cosmetic bottles of different sizes. Furthermore, the motor body 3 is fixed to the lifting frame 2. When the output shaft 31 rotates, it drives the mounting arm 4 and the spray nozzle 5 to rotate around the axis, achieving uniform spraying.

[0030] According to the appendix Figure 2 and attached Figure 3 As shown, a mounting plate 52 is fixedly connected to the nozzle 5. The mounting plate 52 is fixedly connected to the mounting arm 4 by bolts, which allows the nozzle 5 to be quickly disassembled and replaced, facilitating maintenance or adjustment of the spraying mode. Furthermore, the pumping pipe 51 is connected to an external pump unit, which delivers the pigment to the nozzle 5. The nozzle 5 uses an atomizing nozzle to ensure that the pigment is evenly sprayed on the surface of the glass bottle.

[0031] According to the appendix Figure 4 and attached Figure 5 As shown, a sleeve 61 is fixedly connected to the base 6, and a locking block 71 is fixedly connected to the rubber stopper 7. The locking block 71 is engaged within the sleeve 61, and a locking assembly 8 is provided on the base 6 for locking the position of the locking block 71. Furthermore, the rubber stopper 7 is made of an elastic material, which can effectively seal the mouth of the glass cosmetic bottle and prevent pigments from entering the bottle.

[0032] According to the appendix Figure 5 and attached Figure 6As shown, the locking assembly 8 includes a sleeve 81, a pin 82, and a spring 83. The sleeve 81 is fixedly connected to the base 6; the pin 82 is slidably connected inside the sleeve 81, and the locking assembly 8 locks the block 71 by engaging the pin 82 in the lock hole 72; the spring 83 is fixedly connected between the pin 82 and the sleeve 81. Furthermore, the pin 82 has a handle on its side for easy manual operation; the sleeve 81 has a groove on its side that limits the position of the handle of the pin 82, ensuring that the pin 82 will not disengage from the sleeve 81 during sliding. When the block 71 is inserted into the sleeve base 61, the pin 82 automatically engages in the lock hole 72 under the action of the spring 83, achieving rapid locking; pulling the handle releases the lock, facilitating the replacement of the rubber plug 7.

[0033] According to the appendix Figure 1 To be continued Figure 6 As shown, the output shaft 31 is connected to the base 6 via a bearing, ensuring the base 6 remains relatively stable when the output shaft 31 rotates, thus ensuring the rubber stopper 7 can effectively secure the glass cosmetic bottle. Furthermore, the motor body 3 is a stepper motor or a servo motor, which can precisely control the speed and angle of the output shaft 31, enabling programmable control of the spraying path.

[0034] According to the appendix Figure 2 To be continued Figure 6 As shown, the mounting arm 4 is an adjustable-length arm-shaped structure, bolted to the output shaft 31, allowing adjustment of the radial position of the nozzle 5 to accommodate glass cosmetic bottles of different diameters. Furthermore, the pumping pipe 51 is a flexible hose to prevent tangling during rotation.

[0035] According to the appendix Figure 1 To be continued Figure 6 As shown, it is particularly important to emphasize that the electric push rod 11, the motor body 3, and the pump set are all connected to the control system. The control system can automatically adjust the lifting, rotation, and spraying parameters based on a preset program to achieve automated production. Furthermore, the frame 1 is made of aluminum alloy, which is lightweight and sturdy, ensuring the stability of the device.

[0036] According to the appendix Figure 1 To be continued Figure 6 As shown, it is particularly important to emphasize that the rubber stopper 7 can be customized according to the shape of the glass cosmetic bottle opening. The locking block 71 and the sleeve 61 adopt a polygonal snap-fit ​​design to prevent relative rotation and ensure reliable sealing. The spring 83 of the locking assembly 8 is a compression type, providing continuous locking force to prevent the rubber stopper 7 from loosening during the spraying process.

[0037] Example 1: This example uses a cylindrical glass cosmetic bottle with a diameter of 5cm and a height of 10cm as an example, combined with the attached... Figure 1 To be continued Figure 6 Detailed explanation of the workflow: The workflow is as follows:

[0038] 1. Device debugging: According to the specifications of the cylindrical glass cosmetic bottle to be sprayed, select the appropriate rubber stopper 7, pull the handle 821 of the locking component 8 to compress the spring 83 and move the pin 82 to the outside of the sleeve 81, align the locking block 71 on the top of the rubber stopper 7 with the opening of the sleeve 61 and insert it into the sleeve 61, release the handle 821, and under the pre-tightening force of the spring 83, the small diameter end of the pin 82 is inserted into the locking hole 72 on the locking block 71, thus completing the installation of the rubber stopper 7;

[0039] 2. Workpiece clamping: Place the cylindrical glass cosmetic bottle to be sprayed in the target position, ensuring that the bottle axis is vertical. Start the electric push rod 11. The output end of the electric push rod 11 extends and drives the lifting frame 2 to move downward along the slide rail of the frame 1 until the rubber stopper 7 is fully inserted into the bottle mouth of the glass cosmetic bottle, thereby closing the bottle mouth. Then, turn off the electric push rod 11.

[0040] 3. Spraying preparation: Connect the pump pipe 51 to the pump set containing the corresponding color pigment, check the sealing of each connection, adjust the output pressure of the pump set to 0.3MPa, and ensure that the distance between the nozzle of the spray head 5 and the outer surface of the glass cosmetic bottle is 5cm.

[0041] 4. Start spraying: Simultaneously start the motor body 3 and the pump group. The motor body 3 drives the output shaft 31 to rotate at a constant speed of 30r / min. The output shaft 31 drives the mounting arm 4 and the nozzle 5 to rotate synchronously around the glass cosmetic bottle. The pump group delivers the pigment to the nozzle 5 through the pumping pipe 51 and sprays it onto the outer surface of the glass cosmetic bottle after atomization from the nozzle.

[0042] 5. Complete the spraying: After spraying for 30 seconds, first turn off the pump set. After the nozzle 5 stops spraying paint, turn off the motor body 3, start the electric push rod 11 to retract its output end, drive the lifting frame 2 and the rubber stopper 7 to move upward and separate from the mouth of the glass cosmetic bottle. Finally, remove the sprayed glass cosmetic bottle and send it to the drying process.

[0043] Example 2: This example uses an irregularly shaped glass cosmetic bottle with a square cross-section and a height of 15cm as an example, combined with the attached... Figure 1 To be continued Figure 6 Detailed explanation of the workflow: The workflow is as follows:

[0044] 1. Device debugging: Replace the rubber stopper 7 according to the bottle mouth specifications of the irregularly shaped glass cosmetic bottle. The replacement method is the same as in Example 1. By loosening the hexagonal bolts on the mounting plate 52, adjust the installation angle of the nozzle 5 so that the nozzle and the side of the square glass cosmetic bottle are at a 45° angle. After adjustment, tighten the bolts again to fix it.

[0045] 2. Workpiece clamping: Place the irregularly shaped glass cosmetic bottle to be sprayed in the processing position, start the electric push rod 11 to lower the lifting frame 2 until the rubber stopper 7 is tightly inserted into the bottle mouth, and then close the electric push rod 11.

[0046] 3. Spraying preparation: Connect the pumping pipe 51 to the pump set, adjust the output pressure of the pump set to 0.4MPa, and set the speed of the motor body 3 to 20r / min according to the side length of the square bottle to ensure that the spray head 5 can evenly cover the surface of the bottle during rotation.

[0047] 4. Start spraying: Start the motor body 3 and pump set. The motor body 3 drives the nozzle 5 to rotate at a constant speed around the irregularly shaped glass cosmetic bottle. Since the nozzle 5 is set at a 45° angle, the atomized pigment can better cover the corners of the square bottle. To ensure uniform spraying, control the spraying time to 45 seconds and keep the pump set pressure stable during this period.

[0048] 5. Complete the spraying: First, turn off the pump set. After the residual pigment in the nozzle 5 is emptied, turn off the motor body 3, start the electric push rod 11 to raise the lifting frame 2, take out the sprayed irregularly shaped glass cosmetic bottle, clean the nozzle 5 nozzle, and prepare for the spraying of the next batch of workpieces.

[0049] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
