Description

Technical Field

[0001] This utility model relates to the field of glass bottle processing technology, and in particular to a device for removing black spots from the bottom of glass bottles. Background Technology

[0002] During the production of glass bottles, black spots often appear on the bottom due to impurities in raw materials, ingredient issues, or defects in the manufacturing process. These black spots not only affect the appearance and light transmittance of the glass bottle, but may also cause safety hazards due to stress concentration, making the glass bottle prone to breakage during use. To solve this problem, it is necessary to remove the black spots from glass bottles with black spots on the bottom.

[0003] However, existing glass bottle bottom black spot removal devices have some shortcomings in practical applications. First, poor versatility is one of their main drawbacks. These devices are often designed to handle only glass bottles of specific diameters, and their adaptability to different sizes is clearly insufficient, making it difficult to meet diverse production needs. Second, the safety measures in existing devices are also relatively weak. Operators are prone to accidentally touching the grinding parts, posing a potential safety risk. Furthermore, glass shards generated during grinding easily fly everywhere, scattering directly onto the work surface, not only polluting the working environment but also adding an extra cleaning burden for workers and reducing work efficiency.

[0004] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0035] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0036] In the modernization of glass bottle production, the requirements for product quality are constantly increasing. The problem of black spots on the bottom of glass bottles, a long-standing production challenge, directly affects the aesthetics and safety of the products. Early on, black spot removal relied mainly on manual sorting and polishing, which was inefficient and yielded inconsistent results. With the development of automation technology, various glass bottle black spot removal devices have emerged. However, existing removal devices often exhibit a lack of versatility; they are often designed to adapt only to specific bottle shapes, proving inadequate for the diverse needs of glass bottle production. Furthermore, operational safety is also a significant issue, with operators facing the potential risk of accidentally touching moving parts while operating existing equipment. Moreover, if the debris generated during polishing is not effectively collected, it will directly pollute the working environment and increase the cleaning burden. To overcome these limitations, this invention proposes a glass bottle bottom black spot removal device, aiming to improve the versatility and safety of black spot removal. The core of this invention lies in the unique combination of its adjustable clamping mechanism 14 and movable removal mechanism 7, providing an effective technical solution to the aforementioned technical bottlenecks.

[0037] To better understand the technical solution of this utility model, the key terms involved in this application are explained first. The clamping mechanism 14 refers to the component used to securely clamp and fix the glass bottle 16, ensuring the stability of the bottle's position during the polishing process. The cleaning mechanism 7 refers to the core component that performs the black spot polishing and removal operation. The cleaning mechanism 7 includes a motor 701, a fixing plate 702, a mounting component, and a polishing disc 703. It effectively removes the black spots by contacting them with the high-speed rotating polishing disc 703. The rotating ring 12 is the mounting carrier of the clamping mechanism 14. It rotates within the fixing ring 5, driving the clamping mechanism 14 to adjust the clamping diameter of the glass bottle 16. The worm gear 2 and the annular worm wheel 4 constitute the core of the adjustment mechanism. The worm gear 2 is driven to rotate by the handle 3, which in turn drives the annular worm wheel 4 and the rotating ring 12 to rotate, achieving precise adjustment of the clamping mechanism 14. The glass bottle bottom black spot removal device of this utility model is mainly used at the end of the glass bottle production line to perform online or offline black spot removal treatment on glass bottles 16 that have been produced but have black spots on the bottom, so as to improve product quality and reduce the number of defective products leaving the factory.

[0038] like Figures 1 to 6 The device for removing black spots from the bottom of glass bottles shown includes a stand 1, characterized in that it further includes:

[0039] A retaining ring 5 is installed on the platform 1;

[0040] A rotating ring 12 is rotatably disposed within a fixed ring 5;

[0041] A plurality of clamping mechanisms 14 are disposed on the rotating ring 12, the clamping mechanisms 14 including:

[0042] Clamping block 1401 is used to clamp glass bottle 16;

[0043] A round rod 13 is fixed on the side wall of the rotating ring 12. Two rotating rods 1402 are rotatably connected to the surface of the round rod 13. The ends of the two rotating rods 1402 are rotatably connected to the two ends of the clamping block 1401, respectively.

[0044] Sleeve 1404 is fixed to the back of clamping block 1401;

[0045] The guide slide rod 1405 is fixed on the inner wall of the fixing ring 5, and the sleeve 1404 is slidably disposed on the guide slide rod 1405 for guiding the movement of the clamping block 1401.

[0046] The motor 701 is mounted on the top of the frame 1 via a moving mechanism. The output shaft end of the motor 701 is fixedly connected to a fixed disk 702. A grinding disc 703 is mounted on one side of the fixed disk 702 via a mounting assembly.

[0047] A transparent protective cover 6 is fixed to the top of the stand 1 and covers the outside of the grinding disc 703.

[0048] During operation, the frame 1 serves as the base of the entire device, providing mounting support for all components. The fixed ring 5 is securely mounted on the frame 1, providing rotational support for the rotating ring 12. The rotating ring 12 is rotatably mounted inside the fixed ring 5, serving as a mounting platform for the clamping mechanism 14. The clamping mechanism 14 is mounted on the rotating ring 12 and is used to clamp and fix the glass bottles 16 to be processed. In this embodiment, the clamping blocks 1401 in the plurality of clamping mechanisms 14 are used to mutually assist in clamping the bottle body, achieving stable clamping of glass bottles 16 of different diameters. As one implementation, the clamping mechanisms 14 can be three or more evenly distributed on the rotating ring 12 to further improve clamping stability. When the rotating ring 12 rotates, the rotating rod 1402 on the round rod 13 can push or pull the clamping blocks 1401 to move radially. The sleeve 1404 is fixed to the back of the clamping block 1401, and the guide slide 1405 is fixed to the inner wall of the fixing ring 5. The sleeve 1404 is slidably mounted on the guide slide 1405 to provide guidance for the movement of the clamping block 1401, ensuring the stability and accuracy of the clamping movement. After the bottle is clamped, the moving mechanism drives the motor 701, which is equipped with a grinding disc 703, to move towards the bottom of the bottle until the grinding disc 703 contacts the black spot on the bottom of the bottle. At the same time, the motor 701 drives the fixed plate 702 and the grinding disc 703 to rotate at high speed to quickly grind and remove the black spot on the bottom of the bottle. The debris generated during the grinding process can be collected by a chip removal mechanism (not shown in the figure). For example, a chip removal hopper 15 and a collection box 11 can be set under the transparent protective cover 6. The debris falls into the chip removal hopper 15 under the action of gravity and is finally guided into the collection box 11 to keep the working environment clean. Throughout the cleaning process, the operator can clearly observe the polishing process through the transparent protective cover 6 to ensure the cleaning effect. After polishing is completed, the operation is reversed to remove the glass bottle 16, completing one black spot removal operation. This utility model's glass bottle 16 black spot removal device, through the above structural design and working method, achieves efficient, safe, and universal glass bottle 16 black spot removal function, effectively solving the shortcomings of existing technologies and possessing broad application prospects.

[0049] As one embodiment of this utility model, it also includes:

[0050] The worm gear 2 is mounted on the frame 1;

[0051] The annular worm wheel 4 meshes with the worm 2, and the side wall of the annular worm wheel 4 is fixedly connected to the end of the round rod 13 near one side of it;

[0052] The handle 3 is connected to the worm gear 2 and is used to drive the worm gear 2 to rotate;

[0053] The worm 2 is set vertically, the handle 3 is set at the top of the worm 2, and the annular worm wheel 4 is set horizontally and meshes with the worm 2.

[0054] During operation, to drive the rotating ring 12 to rotate, this invention employs a transmission mechanism consisting of a worm gear 2 and an annular worm wheel 4. The worm gear 2 is mounted on the frame 1, and the annular worm wheel 4 meshes with it. The annular worm wheel 4 is fixedly connected to the rotating ring 12 via a round rod 13. A handle 3 is connected to the worm gear 2. By rotating the handle 3, the operator can drive the worm gear 2 to rotate, which in turn drives the annular worm wheel 4 and the rotating ring 12 to rotate synchronously. By rotating the handle 3, the rotation angle of the rotating ring 12 can be precisely adjusted, thereby adjusting the clamping diameter of the clamping mechanism 14 to accommodate glass bottles 16 of different sizes.

[0055] As one embodiment of this utility model, a rubber pad 1403 is provided on the clamping surface of the clamping block 1401. The rubber pad 1403 is located between the clamping block 1401 and the glass bottle 16, and is used to provide buffer protection when clamping the glass bottle 16.

[0056] To further enhance the reliability and safety of the device when clamping the glass bottle 16 during operation, an innovative rubber gasket 1403 is added to the clamping surface where the clamping block 1401 directly contacts the glass bottle 16. This rubber gasket 1403 is cleverly positioned between the contact surfaces of the clamping block 1401 and the glass bottle 16, forming a flexible buffer layer. The rubber gasket 1403 can be fixed in various ways. For example, it can be bonded using a high-performance industrial adhesive to firmly adhere the rubber gasket 1403 to the clamping surface of the clamping block 1401; alternatively, it can be mechanically fixed using a slot-and-groove mechanism. A slot is pre-drilled on the clamping surface of the clamping block 1401, and a matching retaining strip is provided on the edge of the rubber gasket 1403. Fixing is achieved through the interlocking of the retaining strip and the slot. This method facilitates the quick replacement and maintenance of the rubber gasket 1403.

[0057] In summary, by adding a rubber pad 1403 to the clamping block 1401, the technical solution of this utility model can effectively avoid rigid contact between the clamping block 1401 and the bottle body when clamping the glass bottle 16. The elastic deformation of the rubber pad 1403 absorbs the impact force during the clamping process, thereby clamping the bottle body gently and steadily. This significantly reduces the risk of bottle breakage due to excessive or uneven clamping force, further improves the reliability and practicality of the device, and provides a more complete guarantee for the safe and efficient processing of the glass bottle 16.

[0058] As one embodiment of this utility model, the moving mechanism includes:

[0059] The slide rail 10 is fixed on the frame 1, and the slide seat 8 is slidably connected to the slide rail 10. The motor 701 is fixedly installed on the top of the slide seat 8.

[0060] An electric cylinder 9 is fixed on the frame 1, and the telescopic end of the electric cylinder 9 is connected to the sliding seat 8 to drive the sliding seat 8 to slide.

[0061] During operation, after the glass bottle 16 is clamped, the electric cylinder 9 is started. The electric cylinder 9 drives the sliding seat 8 to slide along the slide rail 10. The sliding seat 8 drives the cleaning mechanism 7 to move towards the bottom of the glass bottle 16 until the grinding disc 703 contacts the black spot on the bottom of the bottle. At the same time, the motor 701 drives the fixed plate 702 and the grinding disc 703 to rotate at high speed to quickly grind and remove the black spot on the bottom of the bottle.

[0062] As one embodiment of this utility model, the mounting assembly includes a clamping ring 704 and a plurality of fixing bolts 705. The clamping ring 704 is disposed on one side of the grinding disc 703, and the plurality of fixing bolts 705 pass through the clamping ring 704 and the grinding disc 703 in sequence and are threadedly connected to the fixing disc 702.

[0063] During operation, the main function of the clamping ring 704 is to reliably fix the grinding disc 703. The fixing bolt 705 is preferably a high-strength bolt, which passes through the through hole on the clamping ring 704 and mates with the threaded hole on the fixing plate 702. By tightening the fixing bolt 705, the clamping ring 704 can apply a uniform clamping force to the grinding disc 703, and firmly fix the grinding disc 703 on the working surface of the fixing plate 702.

[0064] Furthermore, this method of fixing via the clamping ring 704 and the fixing bolt 705 greatly facilitates the replacement of the grinding disc 703. When it is necessary to replace a worn or damaged grinding disc 703, simply loosen the fixing bolt 705 to quickly remove the clamping ring 704, thereby easily removing the old grinding disc 703 and replacing it with a new one, greatly improving the maintenance efficiency of the device and reducing the maintenance difficulty.

[0065] As one embodiment of this utility model, a collection box 11 is provided inside the frame 1, and a chip discharge hopper 15 is provided below the transparent protective cover 6. The discharge port of the chip discharge hopper 15 is set facing the collection box 11 and is used to collect the chips generated during the grinding process.

[0066] During operation, the main function of the chip hopper 15 is to collect and initially guide the debris generated during the grinding process. The collection box 11 is located at the bottom of the frame 1 to collect the debris introduced by the chip hopper 15. The volume of the collection box 11 can be rationally designed according to actual production needs. By adding the collection box 11 and the chip hopper 15 to the device, the technical solution of this utility model can effectively collect the debris generated during the grinding process, preventing debris from splashing and scattering on the workbench or workshop floor, significantly improving the cleanliness of the working environment, reducing dust pollution, and creating healthier and more comfortable working conditions for operators. At the same time, it also reduces the workload of subsequent workbench cleaning, improves overall work efficiency, and provides a strong guarantee for the cleanliness and efficiency of glass bottle production.

[0067] Working principle of this utility model:

[0068] A glass bottle 16 with black spots on its bottom that needs cleaning is placed between several clamping mechanisms 14, with the bottom of the glass bottle 16 close to one side of the grinding disc 703. Then, by rotating the handle 3, the worm gear 2 is rotated, which in turn drives the annular worm wheel 4 to rotate. The annular worm wheel 4 drives the round rod 13 to rotate the rotating ring 12 within the fixed ring 5. During the rotation of the round rod 13, the angle between the rotating rod 1402 and the clamping block 1401 changes. The rotating rod 1402 pushes or pulls the clamping block 1401 to move it. During the movement of the clamping block 1401, the sleeve 1404 slides along the guide slide rod 1405, thereby adjusting the clamping block 1401 to move closer to the glass bottle 16 and clamp it. A rubber gasket 1403 separates the clamping block 1401 and the glass bottle 16, providing cushioning and protection to prevent the glass bottle 16 from being damaged. The glass bottle 16 is clamped and damaged. The diameter of the circle formed by the clamping block 1401 is adjusted by the annular worm gear 4 to accommodate glass bottles 16 of different diameters. After the glass bottle 16 is clamped and fixed, the extension end of the electric cylinder 9 drives the sliding seat 8 to slide on the slide rail 10, which in turn drives the cleaning mechanism 7 to move synchronously until one side of the grinding disc 703 contacts the bottom of the glass bottle 16. At the same time, the motor 701 drives the fixed plate 702 to rotate the grinding disc 703 to grind the bottom of the glass bottle 16, cleaning the black spots on the bottom of the glass bottle 16. The grinding debris falls into the chip hopper 15 and into the collection box 11 for collection. The transparent protective cover 6 surrounds the grinding disc 703 on the inside, effectively preventing accidental contact by personnel while allowing the grinding process to be observed. The grinding disc 703 can be replaced by removing the fixing bolt 705.

[0069] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
