Description

Technical Field

[0001] This invention relates to the field of glass bottle neck trimming machines, and more particularly to a glass bottle neck trimming machine with an automatic cutting structure for molten glass at the bottle neck. Background Technology

[0002] The glass bottle neck trimming machine is mainly used for precise cutting and trimming of glass bottle necks, ensuring a flat, smooth, and uniform size, thus improving sealing and aesthetics. Its core functions include eliminating burrs on the bottle neck, adjusting height deviations, and standardizing bottle neck diameters. It is suitable for glass packaging production lines in the food, beverage, pharmaceutical, and cosmetic industries. Its applications cover the production of various glass containers such as beer bottles, sauce bottles, infusion bottles, and perfume bottles, and it is particularly indispensable in high-end packaging and automated filling processes.

A collection box is inserted into the slot.

[0008] As a further embodiment of the present invention: the extended end of the hydraulic push rod is provided through the slide groove through the support plate, and the cutter is movably disposed below the support frame along the slide groove by the support plate and the hydraulic push rod in cooperation with the first electric push rod.

[0009] As a further embodiment of the present invention: a support plate is provided on the upper end of the worktable and on the left side of the cutting groove. A second horizontal groove is provided on one side of the support plate. A slider is provided inside the second horizontal groove. Guide rails are provided on the side wall of the support plate and near both sides. A vertical plate is slidably provided on the guide rails. An infrared sensor is provided on the side wall of the vertical plate.

[0010] As a further embodiment of the present invention: a motor is provided on one side of the support plate, a lead screw is provided on the rotating shaft of the motor, an image detection mechanism is provided on the upper end of the support plate and near the conveyor belt, and a reflector is provided on the upper end of the worktable and on the other side of the support plate.

[0011] As a further embodiment of the present invention: the lead screw extends into the second transverse groove and is threadedly connected to the slider; the vertical plate is movably mounted on one side of the support plate along the guide rail via the motor, lead screw, and second transverse groove in cooperation with the slider; and the output ends of the image detection mechanism and the infrared sensor are both electrically connected to the input end of the control terminal.

[0012] As a further embodiment of the present invention: a material plate is provided on the conveyor belt, a plurality of first clamping plates are provided on the material plate, two sets of first transverse grooves are provided on the material plate and on one side of the first clamping plates, a second electric push rod is provided on the inner side wall of the first transverse groove, and a second clamping plate is provided at the end of the second electric push rod and above the material plate.

[0013] As a further embodiment of the present invention: the inner sidewalls of the first clamping plate and the second clamping plate are provided with grooves near the corners, the inner sidewalls of the grooves are provided with four sets of telescopic rods, the ends of the four sets of telescopic rods are provided with positioning plates, the upper end of the worktable and the position below the support frame are provided with four sets of vertical slots, the bottom end of the inner sidewall of the vertical slots is provided with a third electric push rod, and the extension end of the third electric push rod and the position inside the vertical slot is provided with a baffle.

[0014] As a further embodiment of the present invention: a spring is wound around the telescopic rod and located on one side of the positioning plate; the positioning plate is movably disposed inside the groove by means of the telescopic rod and the spring; and the second clamping plate is movably disposed on one side of the first clamping plate by means of a third electric push rod along the first transverse groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The molten glass bottle is placed between the first and second clamping plates on the material plate. Then, the second electric push rod pushes the second clamping plate along the first transverse groove towards the position close to the first clamping plate to clamp the glass bottle. During this process, eight positioning plates are located at different positions on the surface of the glass bottle. As the distance between the first and second clamping plates and the glass bottle gradually shortens, the telescopic rod inside the groove is squeezed, causing the spring to compress. The spring applies elastic thrust to different positions of the glass bottle through the positioning plates, fixing the glass bottle. Through the above operation, the first and second clamping plates with adjustable spacing can clamp glass bottles of different diameters. At the same time, the elastic clamping force applied by the positioning plates and springs to the glass bottle effectively prevents the glass bottle from breaking due to excessive force when clamping and fixing it.

[0017] 2. The conveyor belt moves the material plate to a position below the support frame. The first electric push rod is activated, pushing the support plate inside the movable groove. The support plate, via a sliding groove, drives the hydraulic push rod and cutter to move above the cutting groove. The cutter position is adjusted according to the required bottle mouth length. Simultaneously, the motor is activated, causing the lead screw to rotate inside the second horizontal groove. The lead screw, via a slider, moves the vertical plate along the guide rail on one side of the support plate. The position of the infrared sensor is adjusted so that its emitted infrared light is not blocked by the bottle mouth. After the image detection mechanism detects that the glass bottle has moved below the support frame, the conveyor belt stops running. The four sets of third electric push rods move the baffle from the vertical... The material is pushed out of the slot and positioned to one side of the material plate to prevent displacement on the worktable. The control terminal activates the infrared sensor, and the infrared light emitted by the sensor is reflected back by the reflector. If the infrared light is not reflected back, it indicates that the bottle neck is too long. At this time, the control terminal activates the hydraulic push rod to move the cutter downward to cut the bottle neck, making the bottle neck flush. The cut bottle neck waste falls into the collection box inside the slot for centralized processing. Through the above operation, the position of the cutter and the infrared sensor can be adjusted according to the required bottle neck length, which is convenient for cutting glass bottles with different neck lengths, effectively improving the practicality of the device.

Therefore, they should not be construed as limitations on this invention.

[0029] Example 1

[0030] Please see Figure 1-7The present invention provides a technical solution: a glass bottle neck trimming machine with an automatic glass cutting structure for molten glass at the bottle neck, including a workbench 1, a control terminal 32 on the workbench 1, a conveyor belt 2 on the upper end of the workbench 1, a support frame 6 on the left end of the workbench 1 above the conveyor belt 2, a movable groove 7 on the surface of the support frame 6 near one end, two sets of first electric push rods 9 embedded in the side wall of the movable groove 7, a support plate 8 at the end of the two sets of first electric push rods 9, and two sets of sliding grooves 10 at the bottom inside the movable groove 7.

[0031] A material plate 13 is provided on the conveyor belt 2. Several sets of first clamping plates 14 are provided on the material plate 13. Two sets of first transverse grooves 15 are provided on the material plate 13 and on one side of the first clamping plates 14. A second electric push rod 16 is provided on the inner wall of the first transverse groove 15. A second clamping plate 17 is provided at the end of the second electric push rod 16 and above the material plate 13. The second electric push rod 16 pushes the second clamping plate 17 to move along the first transverse groove 15 toward a position close to the first clamping plates 14 to clamp the glass bottle.

[0032] The inner sidewalls of the first clamping plate 14 and the second clamping plate 17 are provided with grooves 18 near the corners. The inner sidewalls of the grooves 18 are provided with four sets of telescopic rods 19. The ends of the four sets of telescopic rods 19 are provided with positioning plates 20. The upper end of the workbench 1 and the position below the support frame 6 are provided with four sets of vertical grooves 21. The bottom end of the inner sidewall of the vertical grooves 21 is provided with a third electric push rod 22. The extension end of the third electric push rod 22 and the interior of the vertical grooves 21 is provided with a baffle 23.

[0033] A spring is wound around the telescopic rod 19 and located on one side of the positioning plate 20. The positioning plate 20 is movably positioned inside the groove 18 through the telescopic rod 19 and the spring. The second clamping plate 17 is movably positioned on one side of the first clamping plate 14 along the first transverse groove 15 through the third electric push rod 22. The eight sets of positioning plates 20 are located at different positions on the surface of the glass bottle. As the position between the first clamping plate 14 and the second clamping plate 17 and the glass bottle gradually shortens, the telescopic rod 19 inside the groove 18 is squeezed, causing the spring to compress. The spring applies elastic thrust to different positions of the glass bottle through the positioning plate 20, thus fixing the glass bottle.

[0034] In use, the molten glass bottle is placed between the first clamping plate 14 and the second clamping plate 17 on the material plate 13. Then, the second electric push rod 16 pushes the second clamping plate 17 along the first transverse groove 15 to move closer to the first clamping plate 14 to clamp the glass bottle. During this process, eight sets of positioning plates 20 are located at different positions on the surface of the glass bottle. As the distance between the first clamping plate 14 and the second clamping plate 17 and the glass bottle gradually shortens, the telescopic rod 19 inside the groove 18 is squeezed, causing the spring to compress. The spring applies elastic thrust to different positions of the glass bottle through the positioning plates 20 to fix the glass bottle. Through the above operation, the first clamping plate 14 and the second clamping plate 17 with adjustable spacing can clamp glass bottles of different diameters. At the same time, the elastic clamping force applied by the positioning plates 20 and the spring to the glass bottle effectively avoids breakage due to excessive force when clamping and fixing the glass bottle.

[0035] Example 2

[0036] Please see Figure 1-7 The present invention provides a technical solution: a glass bottle neck trimming machine with an automatic glass cutting structure for molten glass at the bottle neck, including a workbench 1, a control terminal 32 on the workbench 1, a conveyor belt 2 on the upper end of the workbench 1, a support frame 6 on the left end of the workbench 1 above the conveyor belt 2, a movable groove 7 on the surface of the support frame 6 near one end, two sets of first electric push rods 9 embedded in the side wall of the movable groove 7, a support plate 8 at the end of the two sets of first electric push rods 9, and two sets of sliding grooves 10 at the bottom inside the movable groove 7.

[0037] Two sets of hydraulic push rods 11 are provided at the bottom of the support plate 8. A cutter 12 is provided at the bottom of the two sets of hydraulic push rods 11. A cutting groove 3 is provided on the side wall of the workbench 1 below the cutter 12. A slot 4 is provided at the bottom of the workbench 1 below the cutting groove 3. A collection box 5 is inserted into the slot 4. The bottle neck waste after cutting falls into the collection box 5 inside the slot 4 for centralized processing.

[0038] The extended end of the hydraulic push rod 11 passes through the support plate 8 via the slide groove 10. The cutter 12 is movably positioned below the support frame 6 via the support plate 8 and the hydraulic push rod 11, in conjunction with the first electric push rod 9, along the slide groove 10. When the first electric push rod 9 is activated, it pushes the support plate 8 to move inside the movable groove 7. The support plate 8 drives the hydraulic push rod 11 and the cutter 12 to move above the cutting groove 3 via the slide groove 10. The position of the cutter 12 is adjusted according to the required length of the bottle opening.

[0039] A support plate 24 is provided on the upper end of the workbench 1 and on the left side of the cutting groove 3. A second horizontal groove 25 is provided on one side of the support plate 24. A slider 26 is provided inside the second horizontal groove 25. Guide rails are provided on the side wall of the support plate 24 near both sides. A vertical plate 27 is slidably mounted on the guide rails. An infrared sensor 28 is provided on the side wall of the vertical plate 27. The motor 29 is started to make the lead screw 30 rotate inside the second horizontal groove 25. The lead screw 30 drives the vertical plate 27 to move along the guide rail on one side of the support plate 24 through the slider 26. The position of the infrared sensor 28 is adjusted so that the infrared light emitted by the infrared sensor is not blocked by the bottle mouth.

[0040] A motor 29 is provided on one side of the support plate 24, and a lead screw 30 is provided on the rotating shaft of the motor 29. An image detection mechanism 31 is provided on the upper end of the support plate 24 and near the conveyor belt 2. A reflector 33 is provided on the upper end of the worktable 1 and on the other side of the support plate 24.

[0041] The lead screw 30 extends into the second transverse groove 25 and is threadedly connected to the slider 26. The vertical plate 27 is movably mounted on one side of the support plate 24 along the guide rail through the motor 29, lead screw 30, and second transverse groove 25 in conjunction with the slider 26. The output ends of the image detection mechanism 31 and the infrared sensor 28 are both electrically connected to the input end of the control terminal 32.

[0042] Specifically, the conveyor belt 2 moves the material plate 13 to a position below the support frame 6. The first electric push rod 9 is activated to push the support plate 8 within the movable groove 7. The support plate 8, via the slide groove 10, drives the hydraulic push rod 11 and the cutter 12 to move above the cutting groove 3. The position of the cutter 12 is adjusted according to the required bottle mouth length. Simultaneously, the motor 29 is activated to rotate the lead screw 30 within the second transverse groove 25. The lead screw 30, via the slider 26, drives the vertical plate 27 to move along the guide rail on one side of the support plate 24. The position of the infrared sensor 28 is adjusted so that its emitted infrared light is not blocked by the bottle mouth. After the image detection mechanism 31 detects that the glass bottle has moved below the support frame 6, the conveyor belt 2 stops operating. The four sets of third electric push rods 22 move the baffle 23 from... The vertical groove 21 is pushed out to one side of the material plate 13 for positioning, preventing the material plate 13 from shifting on the worktable 1. The control terminal 32 activates the infrared sensor 28 (model GP2Y0A02YK0F). The infrared light emitted by the infrared sensor 28 is reflected back by the reflector 33. If the infrared light is not reflected back, it means that the bottle mouth of a glass bottle is too long. At this time, the control terminal 32 activates the hydraulic push rod 11 to push the cutter 12 downward to cut the bottle mouth, making the glass bottle mouth flush. The cut bottle mouth waste falls into the collection box 5 inside the slot 4 for centralized processing. Through the above operation, the position of the cutter 12 and the infrared sensor 28 can be adjusted according to the required bottle mouth length, which is convenient for cutting glass bottles with bottle mouths of different lengths, effectively improving the practicality of the device.

[0043] Working principle: A glass bottle with molten neck is placed between the first clamping plate 14 and the second clamping plate 17 on the material plate 13. Then, the second electric push rod 16 pushes the second clamping plate 17 along the first transverse groove 15 towards the position close to the first clamping plate 14 to clamp the glass bottle. During this process, eight sets of positioning plates 20 are located at different positions on the surface of the glass bottle. As the position between the first clamping plate 14 and the second clamping plate 17 and the glass bottle gradually shortens, the telescopic rod 19 inside the groove 18 is squeezed, causing the spring to compress. The spring applies elastic thrust to different positions of the glass bottle through the positioning plates 20, fixing the glass bottle. The conveyor belt 2 moves the material plate 13 to a position below the support frame 6. The first electric push rod 9 is activated to push the support plate 8 to move inside the movable groove 7. The support plate 8 drives the hydraulic push rod 11 and the cutter 12 to move above the cutting groove 3 through the sliding groove 10. The position of the cutter 12 is adjusted according to the required length of the bottle neck. At the same time, the motor 29 is activated to make the lead screw 30 move in the second transverse groove 25. Internally, the lead screw 30 drives the vertical plate 27 to move along the guide rail on one side of the support plate 24 via the slider 26, adjusting the position of the infrared sensor 28 so that the infrared light emitted by the sensor is not blocked by the bottle mouth. After the image detection mechanism 31 detects that the glass bottle has moved to the bottom of the support frame 6, it stops the operation of the conveyor belt 2. The four sets of third electric push rods 22 push the baffle 23 out of the vertical groove 21 to the side of the material plate 13 for positioning, preventing the material plate 13 from shifting on the worktable 1. The control terminal 32 activates the infrared sensor 28 (model GP2Y0A02YK0F). The infrared light emitted by the infrared sensor 28 is reflected back by the reflector 33. If the infrared light is not reflected back, it means that the bottle mouth of the glass bottle is too long. At this time, the control terminal 32 activates the hydraulic push rod 11 to push the cutter 12 downward to cut the bottle mouth, making the glass bottle mouth flush. The cut bottle mouth waste falls into the collection box 5 inside the slot 4 for centralized processing.
