[0002] With the improvement of living and aesthetic standards, manufacturers have to spray various colors of paint on the glass containing products to increase the aesthetics of glass bottles. The spraying quality of glass bottles is affected by the cleanliness of the bottle body.

[0003] In order to improve the spraying quality of glass bottles, a patent with relevant technical announcement number CN213670133U discloses a spraying device for glass bottles, including a conveyor and a fixed component fixedly installed on the upper surface of the conveyor and rotating around its own axis, and also includes a dust removal mechanism and three groups of spraying mechanisms. The glass bottles move forward with the conveyor, and the three groups of spraying mechanisms spray paint on the glass bottles. The glass bottles rotate due to their own needs, and a certain distance is left between adjacent glass bottles. When the three groups of spraying mechanisms are spraying paint, when the nozzle is located between two adjacent glass bottles, the sprayed paint is not sprayed onto the bottle body, which increases the amount of paint used and causes environmental pollution.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the glass bottle spraying device has the defect of causing paint waste. Utility Model Content

[0005] In order to help reduce the problem of paint waste during the spraying process, the present application provides a glass bottle spraying device, which adopts the following technical solution:

[0006] A glass bottle spraying device comprises a frame and a conveyor chain rotatably mounted on the frame, a plurality of mounting mechanisms for mounting glass bottles are fixedly mounted on the conveyor chain, the mounting mechanisms are mounted on the conveyor chain at the same intervals, and further comprises a spraying mechanism for spraying the glass bottles, the spraying mechanism comprises a nozzle, the nozzle is connected to a feed pipe and an air jet pipe, the feed pipe is connected to a diaphragm pump for supplying paint, the air jet pipe is connected to pressurized gas, and further comprises a control mechanism for controlling the nozzle to intermittently spray paint to the glass bottles.

[0007] By adopting the above technical scheme, the glass bottle spraying device installs the glass bottles on the conveyor chain through the installation mechanism, the distance between the glass bottles is the same, the nozzle of the spraying mechanism is connected to the feed pipe and the injection pipe, the feed pipe is connected to the diaphragm pump, and the injection pipe is connected to the pressurized gas. The nozzle is controlled by the control mechanism to intermittently spray paint to the glass bottle. When the glass bottle is at the nozzle position, the nozzle sprays paint to the glass bottle. When the neutral position of two adjacent glass bottles is at the nozzle position, the nozzle stops spraying paint under the control of the control component, which helps to save the amount of paint, improve the utilization rate of the paint, and reduce the pollution of the paint to the environment.

[0008] Optionally, the control mechanism includes a sensing component for sensing the position of the glass bottle, and a control component for controlling the material supply of the diaphragm pump and the gas supply of the injection pipe.

[0009] By adopting the above technical solution, the control mechanism senses the position of the glass bottle through the sensing component, and controls the diaphragm pump feeding and the jet pipe air supply through the control component, which helps to achieve intermittent spraying of paint by the nozzle and save the amount of paint.

[0010] Optionally, the sensing component includes a sensing switch and the sensing switch is fixed to the frame via a switch bracket, the switch bracket is located at an input end of the conveyor chain for conveying glass bottles, and the sensing switch senses the mounting mechanism.

[0011] By adopting the above technical solution, the induction component installs the induction switch on the frame through the switch bracket. The induction switch is located at the input end of the conveyor chain and the induction switch sensing installation mechanism, which helps the induction switch to sense the accuracy of the glass bottle position.

The glass bottle rotates relative to the conveying chain during conveying, which helps the nozzle to spray the paint evenly onto the bottle body, thereby improving the spraying quality of the glass bottle.

[0016] Optionally, the mounting mechanism further includes a rotating assembly for driving the glass bottle to rotate, the rotating assembly includes a pinion gear, the pinion gear is coaxially fixedly connected to the connecting seat, a rack is provided on the frame, and the pinion gear meshes with the rack for transmission.

[0017] By adopting the above technical solution, the rotating component is fixedly connected to the connecting seat through a pinion coaxially, and a rack is arranged on the frame. The pinion meshes with the rack for transmission during the conveying process. The structure is simple, the transmission is reliable, and the power is shared with the conveying chain, which reduces the equipment cost of setting up a separate drive.

[0018] Optionally, the spraying mechanism includes three groups of spraying components and a rotating component that drives the three groups of spraying components to rotate, and the three groups of spraying components spray paint on the upper part, the middle part and the lower part of the glass bottle respectively.

[0019] By adopting the above technical scheme, the spraying mechanism sprays the upper, middle and lower parts of the glass bottle respectively through three groups of spraying components, which helps to improve the uniformity of spraying on the entire bottle body of the glass bottle. The three groups of spraying components are rotated by the rotating component. When the glass bottle being sprayed moves, the rotating component rotates the nozzle while the glass bottle is moving, so that the nozzle is still aimed at the glass bottle for spraying. In the process of rotating the nozzle to the initial position, the nozzle stops spraying under the control of the control component, and waits for the next glass bottle to be sprayed after returning to the initial position.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The glass bottle spraying device controls the nozzle to intermittently spray paint to the glass bottle through a control mechanism. The glass bottle is located at the nozzle position, and the nozzle sprays paint to the glass bottle.

The pinion meshes with the rack for transmission during the conveying process. It has a simple structure, reliable transmission, and shares power with the conveyor chain, reducing the cost of equipment with a separate drive.

[0031] 7. The spraying mechanism sprays the upper, middle and lower parts of the glass bottle respectively through three groups of spraying components, which helps to improve the uniformity of spraying on the entire bottle body of the glass bottle. The three groups of spraying components are rotated by the rotating component. When the glass bottle being sprayed is moving, the rotating component rotates the nozzle while the glass bottle is moving, so that the nozzle is still aimed at the glass bottle for spraying. In the process of rotating the nozzle to the initial position, the nozzle stops spraying under the control of the control component, and waits for the next glass bottle to be sprayed after returning to the initial position.

The control mechanism 6 controls the nozzle 511 to intermittently spray paint to the glass bottle 3. When the glass bottle 3 is located at the nozzle 511 position, the nozzle 511 sprays paint to the glass bottle 3. When the neutral position of two adjacent glass bottles 3 is located at the nozzle 511 position, the nozzle 511 stops spraying paint under the control of the control component 62, which helps to save the amount of paint, improve the utilization rate of the paint, and reduce the pollution of the paint to the environment.

[0044] Reference Figure 1 The control mechanism 6 includes a sensing component 61 for sensing the position of the glass bottle 3, and a control component 62 for controlling the material supply of the pneumatic diaphragm pump 514 and the air supply of the jet pipe 513. The control mechanism 6 senses the position of the glass bottle 3 through the sensing component 61, and controls the material supply of the diaphragm pump 514 and the air supply of the jet pipe 513 through the control component 62, which helps to achieve intermittent spraying of the nozzle 511 and save the amount of paint.

[0045] Reference Figure 1 and Figure 2 The sensing component 61 includes a sensing switch 611 and the sensing switch 611 is fixed on the frame 1 through a switch bracket 612. The switch bracket 612 is located at the input end of the conveyor chain 2 for conveying the glass bottle 3. The sensing switch 611 senses the installation mechanism 4. The sensing component 61 installs the sensing switch 611 on the frame 1 through the switch bracket 612. The sensing switch 611 in the embodiment of the present application is an infrared sensor. The sensing switch 611 is located at the input end of the conveyor chain 2 and the sensing switch 611 senses the installation mechanism 4, which helps the sensing switch 611 to sense the accuracy of the position of the glass bottle 3.

[0046] Reference Figure 1The control component 62 includes a first solenoid valve 621 for controlling the operation of the pneumatic diaphragm pump, a second solenoid valve 622 for controlling the connection between the air supply pipe and the pressurized gas, and the induction switch 611 is interlocked with the signals of the first solenoid valve 621 and the second solenoid valve 622 respectively. The electrical control system realizes the signal interlocking of the induction switch 611 with the first solenoid valve 621 and the second solenoid valve 622 through program control. When the induction switch 611 senses the glass bottle 3, the first solenoid valve 621 controls the diaphragm pump 514 to work normally, and the second solenoid valve 622 controls the air supply pipe to supply air normally. When the induction switch 611 cannot sense the glass bottle 3, the first solenoid valve 621 controls the diaphragm pump 514 not to work, and the second solenoid valve 622 controls the air supply pipe to stop supplying air, which helps to realize the automatic intermittent spraying of paint by the nozzle 511.

[0047] Reference Figure 3 The mounting mechanism 4 includes a connecting piece 41 fixedly connected to the conveying chain 2, one end of the connecting piece 41 is a connecting plate 411 fixedly connected to the conveying chain 2, and the other end is a connecting shaft 412, the connecting plate 411 is fixedly connected to the chain link web of the conveying chain 2, the connecting seat 42 is rotatably arranged on the connecting shaft 412 through a bearing, a bottle seat 43 for mounting a glass bottle 3 is fixedly installed on the connecting seat 42, the mouth of the glass bottle 3 is tightly fitted into the bottle seat 43, and the conveying chain 2 and the glass bottle 3 are connected by the connecting piece 41, which helps to improve the stability of conveying the glass bottle 3 and reduce the shaking of the glass bottle 3 during the conveying process. The glass bottle 3 rotates relative to the conveying chain 2 during the conveying process, which helps the nozzle 511 to spray the paint evenly onto the bottle body, thereby improving the spraying quality of the glass bottle 3.

[0048] Reference Figure 4 The mounting mechanism 4 also includes a rotating assembly 44 for driving the glass bottle 3 to rotate. The rotating assembly 44 includes a pinion 441, which is coaxially fixedly connected to the connecting seat 42 through a key. A rack 11 is provided on the frame 1. The pinion 441 meshes with the rack 11 for transmission during the conveying process. It has a simple structure and reliable transmission. It shares a driving motor with the conveying chain 2, thereby reducing the equipment cost of setting up a driving motor separately.

[0049] Reference Figure 1The spraying mechanism 5 includes three groups of spraying components 51 and a rotating component 52 for driving the three groups of spraying components 51 to rotate. The three groups of spraying components 51 spray paint on the upper, middle and lower parts of the glass bottle 3 respectively. The spraying mechanism 5 sprays the upper, middle and lower parts of the glass bottle 3 respectively through the three groups of spraying components 51, which helps to improve the uniformity of spraying on the entire bottle body of the glass bottle 3. The three groups of spraying components 51 are rotated by the rotating component 52. When the glass bottle 3 being sprayed moves, the glass bottle 3 is moved by rotating the nozzle 511 through the rotation of the rotating component 52, so that the nozzle 511 is still aimed at the glass bottle 3 for spraying. In the process of the nozzle 511 rotating to the initial position, the nozzle 511 stops spraying under the control of the control component 62, and returns to the initial position to wait for the next glass bottle 3 to be sprayed. The rotation of the rotating component 52 further improves the uniformity of spraying on the glass bottle 3.

[0050] Reference Figure 2 The rotary assembly 52 includes a rotary motor 521 and a rotary shaft 522. The rotary motor 521 is fixed on the frame 1, and the rotary shaft 522 is rotatably arranged on the frame 1. The output shaft of the rotary motor 521 is fixedly connected to the rotary shaft 522. The output shaft of the rotary motor 521 is fixedly connected to the rotary shaft 522. In the control method of the rotary motor 521 in the embodiment of the present application, the rotary motor 521 drives the nozzle 511 on the rotary shaft 522 to rotate as the glass bottle 3 moves. The position where the rotation starts is the initial position. The time and speed of the reversal are controlled by the time and speed from the start of rotation to the stop of rotation, so that the nozzle 511 returns to the initial position. In other embodiments of the present application, a proximity switch can also be set at the initial position, and a collision block can be set on the rotary shaft 522. When the proximity switch senses the collision block, the rotary motor 521 stops rotating, so that the nozzle 511 returns to the initial position, which helps to ensure the reliability of the rapid rotation of the rotary shaft 522 and reduce the failure problems caused by the intermediate transmission.

[0051] Reference Figure 5 The spray assembly 51 includes a mounting seat 515 and a connecting rod 516. The mounting seat 515 is detachably fixed on the rotating shaft 522, and the connecting rod 516 is detachably fixed on the mounting seat 515. One end of the connecting rod 516 away from the mounting seat 515 is detachably fixed to the nozzle 511. The spray assembly 51 is detachably fixed on the rotating shaft 522 through the mounting seat 515, and the connecting rod 516 is detachably fixed on the mounting seat 515. The nozzle 511 is detachably fixed on the connecting rod 516, which helps to adjust the angle of the nozzle 511 relative to the glass bottle 3 so that the spraying angle reaches the optimal position to prevent the glass bottle 3 from leaking.

[0052] The working process of a glass bottle spraying device is as follows: the driving motor is started, the driving motor drives the conveying chain 2 to rotate, and the glass bottle 3 rotates under the meshing of the pinion 441 and the rack 11. When the induction switch 611 senses the bottle seat 43 of the glass bottle 3, the first solenoid valve 621 controls the diaphragm pump 514 to feed the material to the feeding pipe 512, and the second solenoid valve 622 controls the supply of pressurized air to the injection pipe 513 to spray paint on the glass bottle 3. At the same time, the rotary motor 521 is started, and the nozzle 511 rotates to the position where the glass bottle 3 moves under the drive of the rotary shaft 522, and continues to spray paint on the glass bottle 3. After the spraying is completed, the first solenoid valve 621 and the second solenoid valve 622 are actuated, the nozzle 511 stops spraying paint, and the rotary motor 521 is quickly reversed to make the nozzle 511 return to the initial position, waiting for the next glass bottle 3 to be sprayed.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application in sequence. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
