Description

Technical Field

[0001] This utility model relates to the field of glass bottle processing, and in particular to a verticality detection device for glass bottle processing. Background Technology

[0002] In the glass bottle manufacturing process, bottle verticality is one of the key indicators for measuring product quality. Bottles with excessive verticality deviation are prone to tilting on high-speed filling lines, leading to liquid spillage or uneven filling. The fit between the bottle mouth and cap depends on verticality; deviation can result in poor sealing, causing leakage or spoilage of the contents. Bottles with poor verticality are also prone to tipping over when stacked, increasing the risk of breakage during transportation. Bottle verticality directly affects its functionality, appearance, and production efficiency. Existing mechanical measurement methods (contact type) for glass bottle verticality involve placing the bottle on a horizontal reference platform, moving a dial indicator along the height of the bottle, recording the maximum offset, and calculating the verticality error between the axis and the reference plane. This measurement method is only suitable for measuring the vertical deviation at specific points on the bottle and is inefficient. Utility Model Content

[0003] The purpose of this invention is to provide a verticality testing device for glass bottle processing, which solves the problems of existing mechanical measurement methods that are only suitable for measuring vertical deviations at specific points on the bottle body and have low measurement efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A verticality detection device for glass bottle processing includes a carrier plate. A chuck is mounted on the carrier plate via bearings, and the center of the chuck is used to clamp a glass bottle. A vertical bracket is fixed to the left side of the carrier plate, and a horizontal cylinder is mounted on the bracket. A detection device is fixed to the output end of the cylinder on the right side. The detection device is used to detect the verticality of the glass bottle. A power supply box is fixed to the outside of the bracket, and an indicator light is mounted on the top of the power supply box. The detection device includes a detection carrier plate and detection probes. The detection carrier plate is vertical and fixedly mounted to the output end of the cylinder. The detection probes are horizontal and vertically distributed on the detection carrier plate. The detection carrier plate includes a movable plate, copper strip grooves, telescopic holes, copper strips, and connectors. The movable plate is fixedly mounted to the output end of the cylinder. The device comprises a movable plate with a vertical copper strip groove at its center, and multiple vertically distributed telescopic holes running through it in the left and right directions, communicating with the copper strip groove. The copper strip is segmented and embedded in the copper strip groove, but not within the telescopic holes. A connector is provided at the top and bottom of the copper strip, with the connector at the top and bottom located outside the top and bottom of the movable plate. The detection probe includes a telescopic column, a limiting plate, a spring baffle, a spring, and a copper ring. The telescopic column is slidably connected within the telescopic holes. A limiting plate is fixed to the left end of the telescopic column, and a spring baffle is fixed to the right end. The limiting plate is located on the left side of the movable plate, and the spring baffle is located on the right side. A spring is sleeved on the telescopic column between the spring baffle and the movable plate. A copper ring is fixed on the telescopic column between the limiting plate and the spring baffle.

[0006] Preferably, the two terminals are connected in series with the signal light and the power supply box via wires.

[0007] Preferably, the right end of the telescopic column is a semi-circular polyurethane contact head.

[0008] Preferably, the movable plate has a fixed plate integrally formed with the front and rear sides, which are structurally symmetrical. The bracket has guide holes at the front and rear that are the same height as and correspond to the fixed plate. A guide post is vertically fixed on the left side of the fixed plate, and the guide post is slidably connected along the guide hole.

[0009] Preferably, the bottom of the chuck is fixed to the output shaft of the servo motor, and the servo motor is fixedly installed on the bottom of the carrier plate.

[0010] Preferably, the chuck includes a connecting plate, a guide groove, a jaw, an adjusting plate, a worm-shaped thread, and a worm-shaped thread groove. The bottom center of the connecting plate is fixed to the output shaft of the servo motor. Three guide grooves are formed radially and at equal angles on the top surface of the connecting plate. The jaw is slidably connected within the guide grooves. A rotatable adjusting plate is coaxially fitted at the bottom of the connecting plate. The top surface of the adjusting plate is provided with a worm-shaped thread, and the bottom surface of the jaw is provided with a worm-shaped thread groove that mates with the worm-shaped thread.

[0011] Preferably, a toggle plate is fixed to the outer circumference of the adjustment disc.

[0012] This utility model has the following beneficial effects:

[0013] The verticality of the bottle is simultaneously detected at different heights using vertically arranged detection probes. When the telescopic column contact head contacts the surface of the glass bottle and all copper rings contact the copper strip, the circuit is energized and the indicator light illuminates, indicating that the bottle meets the standard verticality. If the indicator light does not illuminate, it means that one or more copper rings are not in contact with the copper strip, the circuit is open, and the glass bottle does not meet the standard verticality. Furthermore, the chuck rotation enables full-circumferential scanning of the glass bottle, replacing traditional single-point sampling inspection, increasing the detection range of the glass bottle, and improving the detection efficiency of the glass bottle's verticality.

[0025] like Figure 1-8As shown in this embodiment, a verticality testing device for glass bottle processing includes a carrier plate 1. The carrier plate 1 is made of high-strength aluminum alloy or quenched steel, and its surface is ground to ensure the accuracy of the horizontal reference. It is fixed to the testing table or testing frame by bolts, and a shock-absorbing pad is reserved to reduce external vibration interference. A chuck 2 is mounted on the carrier plate 1 via precision bearings, allowing the chuck 2 to rotate horizontally. The center of the chuck 2 is used to clamp the glass bottle 3 and fix the bottom of the glass bottle 3 to facilitate rotation measurement. A vertical bracket 4 is fixed to the left side of the carrier plate 1, and a horizontal cylinder 5 is mounted on the bracket 4. A detection device 6 is fixed to the output end of the cylinder 5 on the right side, allowing the detection device 6 to move left and right. The detection device 6 is used to detect the verticality of the glass bottle 3. A proportional valve is connected to the tail of the cylinder 5, supporting stepless speed regulation to adapt to different detection speed requirements. A power supply box 7 is fixed outside the bracket 4. The power supply box 7 has a built-in 24V DC switching power supply and relay module to power the cylinder solenoid valve and detection circuit. It is equipped with overcurrent protection and an EMC filter to be compatible with industrial environment interference.The power supply box 7 is equipped with an indicator light 8 on its top. The detection device 6 includes a detection carrier plate 61 and detection probes 62. The detection carrier plate 61 is vertical and fixedly installed with the output end of the cylinder 5. The detection probes 62 are horizontal and vertically distributed on the detection carrier plate 61. The detection carrier plate 61 includes a movable plate 611, a copper strip groove 612, a telescopic hole 613, a copper strip 614, and a connector 615. The movable plate 611 is made of insulating material and fixedly installed with the output end of the cylinder 5. A vertical copper strip groove 612 is formed in the center. Multiple vertically distributed telescopic holes 613 extend through the movable plate 611 in the left and right directions, communicating with the copper strip groove 612. The copper strip 614 is segmented and embedded in the copper strip groove 612, but not within the telescopic holes 613. The top and bottom ends of the copper strip 614 are connected to connectors 615 via a crimping process to reduce contact resistance to ≤0.1Ω. The connectors 615 at the top and bottom are located outside the top and bottom of the movable plate 611 for wire connection. The detection probe 62 is enclosed... The system includes a telescopic column 621, a limiting plate 622, a spring baffle 623, a spring 624, and a copper ring 625. The telescopic column 621 is made of a smooth insulating material and slides along the telescopic hole 613. The length of the longitudinally arranged telescopic columns 621 is determined according to the standard glass bottle. In its natural state, the left end of the telescopic column 621 is flush with the standard glass bottle, and the right end is on the outline of the standard glass bottle. The limiting plate 622 is fixed to the left end of the telescopic column 621, and the spring baffle 623 is fixed to the right side. The limiting plate 622 is located on the movable plate. On the left side of 611, spring baffle 623 is located on the right side of movable plate 611. A spring 624 is sleeved on the telescopic column 621 between spring baffle 623 and movable plate 611. Spring 624 applies a rightward elastic force to telescopic column 621. Spring 624 is a stainless steel compression spring with a preload of 15N to ensure stable contact between telescopic column 621 and bottle body. A copper ring 625 is fixed on telescopic column 621 between limiting plate 622 and spring baffle 623 for conducting current through contact with copper strip 614.

[0026] The two terminals 615 are connected in series with the signal light 8 and the power supply box 7 via wires.

[0027] The right end of the telescopic column 621 has a semi-circular polyurethane contact head to avoid scratching the glass surface.

[0028] The movable plate 611 has a symmetrically formed fixed plate 616 integrally formed at the front and back. The bracket 4 has guide holes 41 at the front and back that are the same height as and correspond to the fixed plate 616. A guide post 42 is vertically fixed on the left side of the fixed plate 616, and the guide post 42 is slidably connected along the guide hole 41. This ensures that the movable plate 611 remains vertical during movement.

[0029] The bottom of the chuck 2 is fixed to the output shaft of the servo motor 9, which is fixedly installed on the bottom of the carrier plate 1, controlling the chuck 2 to rotate at a uniform speed of 60 r / min.

[0030] The chuck 2 includes a connecting plate 21, a guide groove 22, a gripper 23, an adjusting plate 24, a volute thread 25, and a volute thread groove 26. The bottom center of the connecting plate 21 is fixed to the output shaft of the servo motor 9. Three guide grooves 22 are radially and equidistantly formed on the top surface of the connecting plate 21. The gripper 23 is slidably connected within the guide grooves 22. A rotatable adjusting plate 24 is coaxially mounted on the bottom of the connecting plate 21. The top surface of the adjusting plate 24 is provided with a volute thread 25, and the bottom surface of the gripper 23 is provided with a volute thread groove 26 that mates with the volute thread 25. This ensures that the glass bottle 3 is clamped in the center of the connecting plate 21 and has a self-locking function.

[0031] A toggle plate 27 is fixed to the outer circumference of the adjusting plate 24. This allows for easy clamping of the glass bottle 3 by manually rotating the adjusting plate 24.

[0032] The working principle of this utility model is as follows: The rotating adjusting disc 24 causes the gripper 23 to clamp the glass bottle 3 to be tested. The cylinder 5 controls the propulsion speed through a proportional valve, pushing the detection device 6 horizontally along the sliding pair formed by the guide column 42 and the guide hole 41, ensuring that the moving plate 611 always remains vertical. The spring 624 applies a pre-compression force of 15N to the telescopic column 621, pushing the contact head at the right end of the telescopic column 621 to fit tightly against the bottle surface. At this time, the spring 624 is compressed, and the telescopic column 621 moves to the left. When the glass bottle 3 is vertical and not tilted, all the telescopic columns 621 move the same distance. The copper ring 625 contacts the copper strip 614 to conduct the circuit, and the indicator light 8 lights up. The servo motor 9 drives the chuck 2 to rotate at a constant speed of 60 r / min, causing the clamped glass bottle 3 to rotate at a uniform speed. If there is a defect such as a protrusion or pit on the outer wall of the glass bottle 3, then at least one telescopic column 621 at this longitudinal position will be compressed and retracted. The copper ring 625 at the defect will separate from the copper strip 614, causing the circuit to break and the indicator light 8 to not light up.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
