Description

Technical Field

[0001] The utility model relates to the technical field of glass bottle glaze spraying, in particular to a glass bottle colored glaze spraying positioning tool. Background Art

[0002] Colored glaze glass bottles are a kind of glass product obtained by spraying inorganic glaze onto the glass surface and drying it, so that the glaze is sintered on the surface of the glass bottle. After spraying the glaze, the bottle body has a unique appearance and high gloss on the surface of the bottle body. It can produce a variety of different effects such as frosting and baking paint, thereby enhancing the decorativeness and aesthetics of the bottle body.

[0003] In industrial production, a dedicated glazing line is provided. Glass bottles move along the flow direction of the glazing line. A glaze spray gun is fixedly provided on one side of the glazing line, which can spray glaze on the glass bottles moving on the glazing line one by one. In order to ensure the stable movement of the glass bottles on the glazing line and to ensure that the spray gun sprays the same position on each glass bottle, a positioning fixture is also required on the glazing line. The mouth of the glass bottle is inserted upside down into the positioning fixture to limit the position of the glass bottle. For example, in the prior art "bottle electrostatic spraying fixture and electrostatic spraying equipment" (publication number: CN107470061A), the mouth of the glass bottle is placed on the positioning column to fix the glass bottle. However, the prior art still has the following technical problems:

[0004] In industrial processing, there are many types of glass bottles, and the diameters of the bottle mouths of glass bottles vary. The existing positioning tooling can only be applied to the bottle mouth diameter of a single glass bottle. As a result, the positioning tooling needs to be replaced every time different types of glass bottles are switched for batch processing. The tooling switching is very time-consuming and seriously affects the processing efficiency. Utility Model Content

[0005] The utility model provides a glass bottle colored glaze spraying positioning tool, which can solve the problem that the glass bottle positioning tool of the glaze spraying line in the prior art cannot be applied to glass bottles with a variety of different bottle mouth diameters, resulting in tool switching being very time-consuming when switching to production of different products, thereby affecting processing efficiency.

[0006] The present application provides the following technical solutions: A glass bottle colored glaze spraying positioning tool, comprising a connecting rod, a rotating assembly rotatably connected to the upper end of the connecting rod, and a positioning assembly fixed above the rotating assembly;

[0007] The positioning assembly includes a positioning column threadedly connected to the upper end of the rotating assembly and a reducing assembly slidably connected to the positioning column, a positioning plate is fixed to the middle of the positioning column, the positioning plate divides the positioning column into an upper half and a lower half, a plurality of sliding holes evenly distributed along the circumference are radially opened on the rod portion of the upper half of the positioning column, the reducing assembly includes a sliding column slidably connected to the sliding hole of the upper half of the positioning column and a reducing block fixed to the end of the sliding column, a compression spring is provided in the sliding hole, and two ends of the compression spring are respectively fixedly connected to the end of the sliding column and the bottom surface of the sliding hole;

[0008] The outer side of the upper end of the variable diameter block is in the form of an arc surface; the outer diameter of the positioning plate is larger than the maximum outer diameter of the variable diameter block when it is expanded.

[0009] Beneficial effects:

[0010] 1. Strong versatility and helps to improve production efficiency: Through the compression spring connected between the slide post and the slide hole, when the slide post slides in the slide hole, the size of the outer side of the reducer can be adjusted, so that glass bottles of different diameters can be supported and positioned after being inserted into the reducer block. It has strong applicability and is conducive to saving time for tooling replacement when switching products on the production line.

[0011] 2. Improves the convenience and safety of glass bottle positioning: Since the outer side of the upper end of the reducer is an arc surface, this design allows the mouth of the glass bottle to be smoothly inserted along the arc surface when it is inserted into the reducer, thereby improving the convenience of placing the glass bottle. At the same time, the outer arc surface can protect the mouth of the glass bottle and prevent it from being scratched.

[0012] 3. Improved the stability of glass bottle positioning: the outer diameter of the positioning plate is larger than the maximum outer diameter of the reducer when it is expanded, which can ensure that after the mouth of the glass bottle is inserted into the reducer, the upper surface of the positioning plate can support the glass bottle to prevent the glass bottle from loosening and tipping over when moving on the production line.

[0013] Furthermore, the sliding hole and the sliding block are both arranged to be inclined from top to bottom toward the center of the positioning column.

[0014] Beneficial effect: The direction of the sliding hole is set to be inclined toward the center of the positioning column, so that when the mouth of the glass bottle is inserted into the reducing block, the direction of the extrusion force of the mouth of the bottle on the reducing block can be more in line with the inclined direction of the sliding hole, and the slider can be squeezed into the sliding hole more smoothly, thereby improving the reducing speed of the reducing block.

[0015] Furthermore, the lower end of the connecting rod is provided with a thread, and the rod portion of the connecting rod is sequentially sleeved with a support block and a lower limit sleeve fixed to the rod portion of the connecting rod from top to bottom, and the support block is located between the lower limit sleeve and the rotating assembly.

[0016] Beneficial effects: In actual production, the glaze spraying line transmits glass bottles through a chain plate conveyor belt. The thread at the lower end of the connecting rod is used to connect and fix with the threaded hole on the chain plate, so that the conveyor belt drives the entire positioning tooling to circulate along the production line; the support block is used to support the entire rotating assembly and improve the support stability of the rotating assembly. The lower limit sleeve can axially limit the support block to prevent the support block from axial movement, thereby improving the stability of the tooling structure.

[0017] Furthermore, the rotating assembly includes a rotating shaft rotatably connected above the connecting rod and a guide wheel rotatably connected to the rotating shaft, the rotating shaft includes a long rod, a cylinder and a sprocket fixedly connected in sequence from top to bottom, the outer diameter of the cylinder is larger than the outer diameter of the long rod, an upper limit sleeve is also fixed on the rod portion of the long rod, and the guide wheel sleeve is arranged on the rod portion of the long rod between the upper limit sleeve and the cylinder.

[0018] Beneficial effects: In actual production, a chain is provided on one side of the glaze spraying line, and the sprocket of the rotating shaft is meshed with the chain. When the entire positioning tooling is transported on the conveyor belt, the sprocket rotates under the meshing action of the chain, so that the glass bottles on the tooling follow the rotation. The spray gun on the glaze spraying line can spray glaze evenly around the glass bottle, which helps to improve the uniformity and comprehensiveness of the glaze spraying of the glass bottle and ensure the spraying effect of the glass bottle. At the same time, guide grooves are provided on both sides of the glaze spraying line, and the guide wheels roll in the guide grooves. The guide grooves limit the guide wheels, which helps to keep the rotating shaft level during rotation and improve the stability of the rotating shaft during rotation.

[0019] Furthermore, the upper end of the connecting rod extends out of the upper end surface of the supporting block, and a bearing is installed on the end of the extended connecting rod. A bearing hole is opened at the center of the sprocket at the lower end of the rotating shaft, and the outer ring of the bearing is fixed in the bearing hole.

[0020] Beneficial effect: The upper end of the connecting rod is connected to the lower end of the rotating shaft through a bearing, which is convenient for reducing the friction force when the connecting rod and the rotating shaft rotate relative to each other, sharing the radial load, and improving the stability of the rotating shaft and the connecting rod when rotating.

[0021] Furthermore, the upper limit sleeve and the lower limit sleeve are radially provided with screw holes, the rod portion of the long rod of the rotating shaft and the rod portion of the connecting rod are provided with threaded holes, and the upper limit sleeve and the lower limit sleeve are respectively fixed to the rod portion of the long rod and the rod portion of the connecting rod by screws.

[0022] Beneficial effect: The upper limit sleeve and the lower limit sleeve are used to axially limit the guide wheel and the support block respectively, ensuring that the position of the support block of the guide wheel does not move axially, thereby improving the stability of the tooling when it circulates on the production line.
