Description

Technical Field

[0001] This utility model relates to the technical field of glass wine bottle production and processing, specifically to a spray painting device for wine bottle bodies. Background Technology

[0002] In the production and processing of glass wine bottles, after the glass bottle is formed and quality inspection is completed, it needs to be painted. Glass wine bottles typically consist of the bottle mouth, neck, body, and bottom from top to bottom. The most common glass wine bottle has an inner surface of the bottle mouth that slopes outward from top to bottom, and an inner surface of the neck that slopes outward from bottom to top. The bottle body is cylindrical or cuboid.

[0003] The existing painting equipment used for painting glass bottles typically includes a conveyor belt, a drive unit for driving the conveyor belt, a support unit fixed on the conveyor belt, and a painting unit located on one side of the conveyor belt. The support unit includes a support rod and a connector. The lower end of the support rod is connected to the conveyor belt, and the upper end of the support rod is fixedly connected to the connector. The connector is used to insert and fix the bottle neck of the glass bottle. The inner circumferential surface of the bottle neck and the connector are interference fit. The connector can be made of rubber.

[0004] Before the support unit reaches the painting section, the worker first holds the glass bottle upside down, then inserts the bottle neck downwards into the connector to begin painting. After painting, the bottle neck is pulled upwards from the connector to remove the bottle. However, because the inner circumference of the bottle neck and the connector are interference-fitted, the worker needs to exert considerable force to insert or remove the bottle neck, making the overall operation quite strenuous. Utility Model Content

[0005] This utility model aims to provide a spray painting device for wine bottles, in order to solve the technical problem in the prior art that when inserting and removing glass wine bottles, the operator needs to exert a lot of force to insert or remove the bottle mouth from the connector before the support reaches the spray painting section and after the support passes the spray painting section, making the overall operation process quite laborious.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A painting device for wine bottles includes a frame, a conveyor belt, a support unit, a painting unit, and a drive unit. The conveyor belt is mounted on the frame and is used to carry and transport glass wine bottles. The support unit is rotatably connected to the conveyor belt, and the rotation center line of the support unit is perpendicular to the conveying plane of the conveyor belt. The support unit is slidably fitted to the bottle mouth, neck, and inner circumferential surface of the bottle body. The support unit can be used to press against the inner circumferential surface of the bottle body. The painting unit is located on one side of the frame and is used to paint the glass wine bottles transported to the painting unit position.

[0009] Furthermore, there are multiple support parts, and the multiple support parts are arranged at even intervals along the conveying direction of the conveyor belt.

[0010] Furthermore, the support part includes a support rod and a clamping member. The support rod is fixed on the conveying plane of the conveyor belt, and the clamping member is fixed on the upper end of the support rod. The clamping member is slidably engaged with the bottle mouth, neck, and inner circumferential surface of the glass bottle. The clamping member can be used to clamp against the inner circumferential surface of the glass bottle body.

[0011] Furthermore, the outer circumferential surface of the upper end of the support rod is provided with a first groove and a second groove. The first groove and the second groove are both arranged along the axis of the support rod. The first groove and the second groove are directly opposite each other. The depth of the first groove and the depth of the second groove are the same. The abutting member includes a first telescopic post and a second telescopic post. The first telescopic post and the second telescopic post have the same telescopic length. The first telescopic post is slidably fitted in the first groove, and the second telescopic post is slidably fitted in the second groove. The end of the first telescopic post located outside the first groove and the end of the second telescopic post located outside the second groove can be used together to abut against the inner circumferential surface of the glass bottle.

[0012] Furthermore, the first telescopic column includes a first support column and a first helical spring. One end of the first helical spring is fixedly connected to the bottom of the first groove, and the other end of the first helical spring is fixedly connected to the first support column. The end face of the first support column away from the first helical spring is divided into a first upper part and a first lower part. The outer surface of the first upper part is inclined from bottom to top, and the outer surface of the first lower part is inclined from top to bottom. The second telescopic column includes a second support column and a second helical spring. One end of the second helical spring is fixedly connected to the bottom of the second groove, and the other end of the second helical spring is fixedly connected to the second support column. The end face of the second support column away from the second helical spring is divided into a second upper part and a second lower part. The outer surface of the second upper part is inclined from bottom to top, and the outer surface of the second lower part is inclined from top to bottom. The other ends of the first support column and the second support column can be used together to abut against the inner circumferential surface of the glass bottle.

[0013] Furthermore, it also includes a bearing housing and a bearing. The bearing housing is fixed on the conveying plane of the conveyor belt and located directly below the support rod. The bearing is fixedly installed inside the bearing housing. The support rod is arranged perpendicular to the conveying plane of the conveyor belt. A rotating shaft is fixedly installed at the lower end of the support rod. The upper end of the rotating shaft is fixedly connected to the lower end of the support rod. The lower end of the rotating shaft is fixed inside the inner ring of the bearing. The axis of the rotating shaft is collinear with the axis of the support rod.

[0014] Furthermore, the painting section includes a mounting plate and painting components. The mounting plate is disposed on one side of the conveyor belt, and there are multiple painting components, which are evenly spaced along the conveying direction of the conveyor belt.

[0015] Furthermore, the paint spraying component includes a mounting rod and a paint spray nozzle. The lower end of the mounting rod is fixedly connected to the upper surface of the mounting plate. The paint spray nozzle is slidably connected to the mounting rod and rotatably connected to the mounting rod. The rotation center line of the paint spray nozzle is perpendicular to the mounting rod.

[0016] Furthermore, the painting component also includes a first mounting ring, a connecting rod, a second mounting ring, a mounting crossbar, a first locking member, and a second locking member. The annular hole of the first mounting ring mates with the mounting vertical rod. One end of the connecting rod is rotatably connected to the first mounting ring, and the other end of the connecting rod is fixedly connected to the second mounting ring. The mounting crossbar is disposed within the second mounting ring, and the paint spray nozzle is fixedly disposed at the end of the mounting crossbar facing the conveyor belt. The first locking member is used to lock the first mounting ring so that the first mounting ring cannot slide. The second locking member is used to lock the connecting rod so that the connecting rod cannot rotate.

[0017] The beneficial effects of this utility model are as follows:

[0018] Before using the bottle painting device of this invention to paint glass bottles, a worker stands at the input end of the conveyor belt, holds the glass bottle upside down, aligns the bottle mouth with the support, and presses the bottle down. The support slides from the bottle mouth into the bottle neck and then into the bottle body, pressing the inner circumference of the bottle body against the support, thus fixing the bottle to the support. Then, the drive unit drives the conveyor belt to transport the support holding the glass bottle to the painting section. Because the support is rotatably connected to the conveyor belt, its rotation center line is perpendicular to the conveying plane of the conveyor belt. Consequently, the glass bottle fixed to the support can also rotate, its rotation center line perpendicular to the conveying plane of the conveyor belt. When the painting section sprays paint onto the outer surface of the glass bottle, the bottle rotates due to the impact force generated by the paint spraying, allowing the painting section to paint the bottle more evenly at the painting position. After the glass bottle is painted, another worker stands at the output end of the conveyor belt. The glass bottle is then transported away from the painting area until it reaches the output end of the conveyor belt. The worker lifts the glass bottle up, and the support slides down from the body of the glass bottle to the neck, then from the neck to the mouth, and finally detaches from the mouth, allowing the glass bottle to be pulled off the support.

[0019] When using the painting device for wine bottles of this utility model, it is easier for workers to insert or pull the glass wine bottle from the support.

[0020] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] In the above description of this utility model, it should be noted that the terms "one side," "the other side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0033] Please see Figure 1-6 This utility model provides a technical solution: a spray painting device for wine bottles, including a frame 1, a conveyor belt 2, a support part, a spray painting part, and a drive part. The conveyor belt 2 is mounted on the frame 1 and is used to carry and transport glass wine bottles. The support part is rotatably connected to the conveyor belt 2, and the rotation center line of the support part is perpendicular to the conveying plane of the conveyor belt 2. The support part is slidably fitted to the bottle mouth, neck, and inner circumferential surface of the bottle body. The support part can be used to press against the inner circumferential surface of the bottle body. The spray painting part is located on one side of the frame 1 and is used to spray paint the glass wine bottles transported to the spray painting part position. The drive part is used to drive the conveyor belt 2 to perform conveying movement.

[0034] Before using the bottle painting device of this invention to paint a glass bottle, a worker stands at the input end of the conveyor belt 2, holds the glass bottle upside down, aligns the bottle mouth with the support, and presses the bottle down. The support slides from the bottle mouth into the bottle neck and then into the bottle body, pressing the inner circumference of the bottle body against the support, thus fixing the glass bottle to the support. Then, the drive unit drives the conveyor belt 2 to transport the support holding the glass bottle to the painting section. Because the support is rotatably connected to the conveyor belt 2, and the rotation center line of the support is perpendicular to the conveying plane of the conveyor belt 2, the glass bottle fixed to the support can also rotate. When the painting section sprays paint onto the outer surface of the glass bottle, the glass bottle rotates due to the impact force generated by the paint spraying, allowing the painting section to paint the glass bottle more evenly at the painting position.

[0035] After the glass bottle is painted, another worker stands at the output end of conveyor belt 2. The glass bottle is continued to be transported by conveyor belt 2 away from the painting section until it reaches the output end of conveyor belt 2. The worker lifts the glass bottle up, and the support slides down from the body of the glass bottle to the neck, then from the neck to the mouth, and finally detaches from the mouth, so that the glass bottle can be pulled off the support.

[0036] When using the painting device for wine bottles of this utility model, it is easier for workers to insert or pull the glass wine bottle from the support.

[0037] In this embodiment: the drive unit includes a drive roller, a motor and a driven roller. The drive roller is rotatably connected to one end of the frame 1. The motor is fixed to the frame 1. The output shaft of the motor is fixed to the drive roller. The motor model can be Y160M1-2. The driven roller is rotatably connected to the other end of the frame 1. The driven roller is arranged parallel to the drive roller. The conveyor belt 2 is wound around the drive roller and the driven roller.

[0038] The motor drives the drive roller to rotate, and with the cooperation of the drive roller and the driven roller, the conveyor belt 2 can perform a conveying motion and transport the glass bottles. With this structure, the drive unit can drive the conveyor belt 2 to perform the conveying motion.

[0039] In this embodiment, the conveyor belt 2 includes a first straight section located above the drive roller and the driven roller, a second straight section located below the drive roller and the driven roller, a first arc-shaped section covering the side of the drive roller facing away from the driven roller, and a second arc-shaped section covering the side of the driven roller facing away from the drive roller. One end of the first straight section is integrally formed with the upper end of the first arc-shaped section, and the other end of the first straight section is integrally formed with the upper end of the second arc-shaped section. One end of the second straight section is integrally formed with the lower end of the first arc-shaped section, and the other end of the second straight section is integrally formed with the lower end of the second arc-shaped section. The area used to carry the glass bottles is the upper side of the conveyor belt 2, specifically the upper side of the first straight section. The direction in which the conveyor belt 2 conveys the glass bottles is the direction of movement of the first straight section. The end where the drive roller is located is the input end of the conveyor belt 2, and the end where the driven roller is located is the output end of the conveyor belt 2. The conveying direction of the first straight section is from the drive roller to the driven roller.

[0040] In this embodiment: The frame 1 has first shaft holes at both ends corresponding to the two ends of the drive roller, and each end of the drive roller has a first shaft 51, which is rotatably fitted into the two first shaft holes. The frame 1 also has second shaft holes at both ends corresponding to the two ends of the driven roller, and each end of the driven roller has a second shaft 52, which is rotatably fitted into the two second shaft holes. With this structure, the drive roller can be rotatably connected to one end of the frame 1, and the driven roller can be rotatably connected to the other end of the frame 1.

[0041] In this embodiment, there are multiple support parts, which are evenly spaced along the conveying direction of the conveyor belt 2. With this structure, the conveyor belt 2 can simultaneously support and transport multiple glass bottles, and the painting unit can sequentially paint the passing glass bottles, resulting in high efficiency.

[0042] In this embodiment, the support part includes a support rod 31 and a clamping member. The support rod 31 is fixed on the conveying plane of the conveyor belt 2, and the clamping member is fixed on the upper end of the support rod 31. The clamping member is slidably engaged with the bottle mouth, neck, and inner circumferential surface of the glass bottle, and can be used to clamp the inner circumferential surface of the glass bottle. With this structure, the support part can be slidably engaged with the bottle mouth, neck, and inner circumferential surface of the glass bottle, and can be used to clamp the inner circumferential surface of the glass bottle.

[0043] In this embodiment: the outer peripheral surface of the upper end of the support rod 31 is provided with a first groove 311 and a second groove 312. The first groove 311 and the second groove 312 are both arranged along the axis towards the support rod 31. The first groove 311 and the second groove 312 are directly opposite each other. The depth of the first groove 311 and the depth of the second groove 312 are the same. The abutting member includes a first telescopic post 321 and a second telescopic post 322. The first telescopic post 321 and the second telescopic post 322 have the same telescopic length. The first telescopic post 321 can be slidably fitted in the first groove 311, and the second telescopic post 322 can be slidably fitted in the second groove 312. The end of the first telescopic post 321 located outside the first groove 311 and the end of the second telescopic post 322 located outside the second groove 312 can be used together to abut against the inner peripheral surface of the glass bottle.

[0044] While the worker is holding the glass bottle upside down, both the first telescopic column 321 and the second telescopic column 322 are shortened. The end of the first telescopic column 321 located outside the first groove 311 moves inward into the first groove 311, and the end of the second telescopic column 322 located outside the second groove 312 moves inward into the second groove 312. Then, the bottle mouth is aligned with the support rod 31, and the bottle is pressed down until the upper half of the end of the first telescopic column 321 located outside the first groove 311 and the upper half of the end of the second telescopic column 322 located outside the second groove 312 enter the bottle mouth, thus shortening the length of both the first telescopic column 321 and the second telescopic column 322 until the ends of the first telescopic column 321 and the second telescopic column 322 located outside the second groove 312 are pressed against the inner circumferential surface of the bottle mouth.

[0045] The staff continued to press the glass bottle downwards. The end of the first telescopic column 321 located outside the first groove 311 and the end of the second telescopic column 322 located outside the second groove 312 slid from the bottle mouth into the bottle neck, causing both the first telescopic column 321 and the second telescopic column 322 to extend until the ends of the first telescopic column 321 and the second telescopic column 322 located outside the second groove 312 pressed against the inner circumferential surface of the bottle neck. The ends of the first telescopic column 321 and the second telescopic column 322 located outside the second groove 312 slid upwards within the bottle neck and remained pressed against the inner circumferential surface of the bottle neck throughout the pressing process. That is, both the first telescopic column 321 and the second telescopic column 322 continued to extend to accommodate the gradually expanding bottle neck.

[0046] The worker continues to press the glass bottle downwards. The end of the first telescopic post 321 located outside the first groove 311 and the end of the second telescopic post 322 located outside the second groove 312 slide into the bottle body from the neck. The glass bottle is transparent. When the worker observes that both ends of the first telescopic post 321 and the second telescopic post 322 are located on the bottle body, the pressing stops. These ends then work together to press against the inner circumferential surface of the bottle body, thus securing the glass bottle to the support rod 31. The principle for removing the glass bottle is the same as the principle for inserting it. With this structure, the pressing component can slidably engage with the bottle mouth, neck, and inner circumferential surface of the bottle body, thus securing the bottle body to the inner circumferential surface.

[0047] In this embodiment: the first telescopic column 321 includes a first support column 3211 and a first helical spring 3212. One end of the first helical spring 3212 is fixedly connected to the bottom of the first groove 311, and the other end of the first helical spring 3212 is fixedly connected to the first support column 3211. The end face of the first support column 3211 away from the first helical spring 3212 is divided into a first upper part and a first lower part. The outer surface of the first upper part is inclined from bottom to top, and the outer surface of the first lower part is inclined from top to bottom. The second telescopic column 322 includes a second support column 3221 and... The second helical spring 3222 has one end fixedly connected to the bottom of the second groove 312, and the other end fixedly connected to the second support column 3221. The end face of the second support column 3221 away from the second helical spring 3222 is divided into a second upper part and a second lower part. The outer surface of the second upper part is inclined from bottom to top, and the outer surface of the second lower part is inclined from top to bottom. The other end of the first support column 3211 and the other end of the second support column 3221 can be used together to press against the inner circumferential surface of the glass bottle.

[0048] The worker can pinch the end of the first support column 3211 away from the first helical spring 3212 and the end of the second support column 3221 away from the second helical spring 3222 by hand and apply force towards the axis of the support rod 31. This will compress both the first helical spring 3212 and the second helical spring 3222, thereby allowing the first support column 3211 to slide towards the bottom of the first groove 311 and the second support column 3221 to slide towards the bottom of the second groove 312.

[0049] When the operator releases the end of the first support column 3211 away from the first helical spring 3212 and the end of the second support column 3221 away from the second helical spring 3222, both the first helical spring 3212 and the second helical spring 3222 will return to their original uncompressed state. That is, both the first helical spring 3212 and the second helical spring 3222 will extend in the direction away from the axis of the support rod 31, thereby allowing the first support column 3211 to slide in the direction away from the bottom of the first groove 311 and the second support column 3221 to slide in the direction away from the bottom of the second groove 312.

[0050] The elastic potential energy of the first helical spring 3212 and the second helical spring 3222 allows the length of the first telescopic column 321 and the second telescopic column 322 to adapt to the bottle mouth, neck, and inner circumferential surface of the bottle after the first telescopic column 321 and the second telescopic column 322 enter the bottle mouth. This allows the end of the first support column 3211 away from the first helical spring 3212 and the end of the second support column 3221 away from the second helical spring 3222 to slide and engage with the bottle mouth, neck, and inner circumferential surface of the bottle.

[0051] With this structure, the first telescopic post 321 and the second telescopic post 322 are telescopic structures. The first telescopic post 321 can be slidably fitted in the first groove 311, and the second telescopic post 322 can be slidably fitted in the second groove 312. The end of the first telescopic post 321 located outside the first groove 311 and the end of the second telescopic post 322 located outside the second groove 312 can be used together to press against the inner circumferential surface of the glass bottle.

[0052] Furthermore, because the outer surface of the first upper part of the first support column 3211 is inclined from bottom to top, and the outer surface of the first lower part is inclined from top to bottom, and the outer surface of the second upper part of the second support column 3221 is inclined from bottom to top, and the outer surface of the second lower part is inclined from top to bottom; the inner surface of the bottle mouth is inclined from top to bottom, and the inner surface of the bottle neck is inclined from bottom to top, when the glass bottle is pressed downwards, the outer surfaces of the first upper part of the first support column 3211 and the second upper part of the second support column 3221 can achieve a beveled fit with the inner circumferential surface of the bottle mouth; when the glass bottle is pulled upwards, the outer surfaces of the first lower part of the first support column 3211 and the second lower part of the second support column 3221 can achieve a beveled fit with the bottle neck. With this structure, the glass bottle can be more easily inserted into or removed from the support part.

[0053] In this embodiment, a bearing housing 6 and a bearing are also included. The bearing housing 6 is fixed on the conveying plane of the conveyor belt 2 and located directly below the support rod 31. The bearing is fixedly installed inside the bearing housing 6. The support rod 31 is arranged perpendicular to the conveying plane of the conveyor belt 2. A rotating shaft 7 is fixedly installed at the lower end of the support rod 31. The upper end of the rotating shaft 7 is fixedly connected to the lower end of the support rod 31. The lower end of the rotating shaft 7 is fixed inside the inner ring of the bearing. The axis of the rotating shaft 7 is collinear with the axis of the support rod 31. With this structure, the support part can be rotatably connected to the conveyor belt 2, and the rotation center line of the support part is perpendicular to the conveying plane of the conveyor belt 2.

[0054] In this embodiment, the painting unit includes a mounting plate 41 and painting components. The mounting plate 41 is disposed on one side of the conveyor belt 2, and there are multiple painting components arranged at even intervals along the conveying direction of the conveyor belt 2. With this structure, multiple glass bottles can be painted simultaneously, improving work efficiency.

[0055] In this embodiment, the painting component includes a mounting rod 421 and a paint spray nozzle 422. The lower end of the mounting rod 421 is fixedly connected to the upper surface of the mounting plate 41. The paint spray nozzle 422 is slidably connected to the mounting rod 421 and rotatably connected to the mounting rod 421. The rotation center line of the paint spray nozzle 422 is perpendicular to the mounting rod 421. The model of the paint spray nozzle 422 can be LPA-101. The operator can adjust the height and spray angle of the paint spray nozzle 422. With this structure, the painting component can better and more evenly paint the glass bottle.

[0056] In this embodiment, the painted component also includes a first mounting ring 423, a connecting rod 424, a second mounting ring 425, a mounting crossbar 429, a first locking member 426, and a second locking member 427. The annular hole of the first mounting ring 423 cooperates with the mounting vertical rod 421. One end of the connecting rod 424 is rotatably connected to the first mounting ring 423. A circular ring 428 is fixedly provided on the outer circumferential surface of the first mounting ring 423. The center line of the circular ring 428 is perpendicular to the mounting vertical rod 421. The axis of the connecting rod 424 is collinear with the center line of the circular ring 428. One end of the connecting rod 424 can rotate within the inner cavity of the circular ring 428. The other end of the connecting rod 424 is fixedly connected to the second mounting ring 425. The mounting crossbar 429 is disposed inside the second mounting ring 425. The paint spray nozzle 422 is fixedly disposed at the end of the mounting crossbar 429 facing the conveyor belt 2. The first locking member 426 is used to lock the first mounting ring 423 so that the first mounting ring 423 cannot slide. The second locking member 427 is used to lock the connecting rod 424 so that the connecting rod 424 cannot rotate. With this structure, the paint spray nozzle 422 can be slidably connected to the mounting vertical rod 421, and the paint spray nozzle 422 can be rotatably connected to the mounting vertical rod 421. The rotation center line of the paint spray nozzle 422 is perpendicular to the mounting vertical rod 421.

[0057] In this embodiment: the outer circumferential surface of the first mounting ring 423 is recessed inward to form a first threaded hole, which penetrates both the outer and inner circumferential surfaces of the first mounting ring 423. The first locking member 426 is a first bolt, which is screwed into the first threaded hole, and the screw-in end of the first bolt is used to abut against the outer circumferential surface of the mounting rod 421; the outer circumferential surface of the ring 428 is recessed inward to form a second threaded hole, which penetrates both the outer and inner circumferential surfaces of the ring 428. The second locking member 427 is a second bolt, which is screwed into the second threaded hole, and the screw-in end of the second bolt is used to abut against the outer circumferential surface of the connecting rod 424.

[0058] Rotating the first bolt within the first screw hole causes its screw-in end to press against the outer circumferential surface of the mounting rod 421, preventing the first mounting ring 423 from sliding up and down on the mounting rod 421. Rotating the first bolt within the first screw hole causes its screw-in end to rotate away from the outer circumferential surface of the mounting rod 421, allowing the first mounting ring 423 to slide up and down on the mounting rod 421. Rotating the second bolt within the second screw hole causes its screw-in end to press against the outer circumferential surface of the connecting rod 424, preventing the connecting rod 424 from rotating within the ring 428. Rotating the second bolt within the second screw hole causes its screw-in end to rotate away from the outer circumferential surface of the connecting rod 424, allowing the connecting rod 424 to rotate within the ring 428. With this structure, the first locking member 426 can be used to lock the first mounting ring 423, preventing it from sliding; the second locking member 427 can be used to lock the connecting rod 424, preventing it from rotating.
