Description

Technical Field

[0001] The utility model relates to the field of glass processing, in particular to a glass cold cutting device. Background Art

[0002] In factories, glass cups are mostly formed by blowing technology, that is, molten glass falls into a mold, and then molten glass is put in for blowing. The softened glass is pressed in the space between the inner and outer molds to form the initial shape of the glass cup. However, in this process, an excess part, the cap mouth, will be formed above the mouth of the glass cup. Before the finished cup is completed, the excess cap mouth part needs to be removed by flame cutting. This step is a key process for the processing and shaping of the glass cup. Usually, the cap mouth can be hot cut, which is to heat the cap mouth and soften it before cutting it quickly. The above cutting method often causes the product's mouth edge to be thicker and have glass drops, and may cause the mouth edge shape to be uneven. Therefore, a cold cutting device suitable for industrial glass cup production is proposed. Utility Model Content

[0003] The utility model aims to provide a glass cold cutting device, so as to propose a cold cutting device suitable for the production of industrial glass cups.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a glass cold cutting device, including a fixed frame, a rotating disk and a cutting part arranged on one side of the fixed frame, the rotating disk is mounted on the fixed frame and can rotate relative to the fixed frame, a plurality of conveying frames for conveying glass cup blanks are arranged around the rotating disk, the conveying frames can rotate relative to the rotating disk, the cutting part includes a mounting seat and a laser cutting mechanism arranged on the mounting seat, a heating gun aimed at the bottom of the conveying frame is also arranged behind the laser cutting mechanism, and when the rotating disk drives the conveying frame to move, the conveying frame rotates itself at the same time.

[0005] The beneficial effects of this program are:

[0006] When the conveyor frame is close to the laser cutting mechanism on the driving frame of the rotating disk, the laser cutting mechanism performs laser cutting on the glass cup blank, leaving a mark on the glass cup blank. The conveyor frame can rotate by itself, which can ensure that the laser cutting mechanism emits laser, so that the entire mouth of the glass cup blank is left with a complete circular mark. After that, the heating gun is aimed at the bottom of the conveyor frame to heat the glass cup mouth and burn it circumferentially. Under the effect of thermal expansion and contraction, the cap mouth automatically falls off after heating. The combined processing method of laser cutting and thermal expansion and contraction can make the mouth edge of the glass cup smoother and more uniform, avoiding the problems of thick edges and glass drops caused by traditional thermal cutting. The automated setting of the conveyor frame and the rotating disk enables the glass cup blank to be cut and heated continuously, greatly improving production efficiency.

[0007] Preferably, as an improvement, a second turntable is fixed on the top of the rotating disk, and a plurality of first sprockets are arranged in a circumferential array on the second turntable. A plurality of motors are provided to drive the first sprockets to rotate, and chains are tensioned on the plurality of first sprockets. The conveying frames are connected to the second sprockets, the connecting parts and the vacuum suction cups in sequence from top to bottom, and a connecting ring is provided to limit the conveying frame on the rotating disk, and the second sprockets are meshed with the chains.

[0008] The beneficial effect is as follows: through the above arrangement, when the rotating disk rotates relative to the fixed frame, the chain engages with the multiple second sprockets, thereby driving the conveying frame to rotate relative to the rotating disk. On the one hand, when the rotating disk drives the glass cup blank to rotate, it is convenient for the laser cutting mechanism to perform uniform laser cutting on a circle around the glass cup blank. On the other hand, the glass cup blank can be in contact with the heating gun in the circumference, so that the bottom of the glass cup blank is evenly heated, so that the cap mouth can fall as a whole without causing local residue. The uniform laser cutting and heating treatment make the glass cup mouth smooth and flawless, thereby improving the appearance quality and performance of the finished product.

[0009] Preferably, as an improvement, laser cutting can leave a notch on the corresponding glass blank, and the heating gun is aimed at a position 1-2 cm below the notch to heat.

[0010] The beneficial effects are: laser cutting leaves precise marks on the glass cup blank, providing a clear fracture line for subsequent heating and fracture. The heating gun is aimed at a position 1-2 cm below the mark for heating, which can make the cap edge break neatly along the mark due to thermal expansion and contraction. The heating gun is positioned 1-2 cm below the mark, which can accurately control the heating range to heat only the cap edge, reduce the thermal impact on other parts of the glass cup blank, and avoid deformation and damage to the glass cup blank.

[0011] Preferably, as an improvement, a receiving plate is provided at the bottom of the fixed frame, and a plurality of support plates for receiving the cap mouth are provided circumferentially at the bottom of the rotating plate, and the support plates are all opposite to the conveying frame. A push plate is also inclined on the mounting seat, and the push plate pushes the cap mouth off the support plate.

[0012] The beneficial effects are: the rotating disk preliminarily collects the fallen cap mouth, and then pushes the cap mouth down through the pushing plate, and collects the waste material from the cap mouth twice, avoiding the cap mouth from being damaged during the falling process, causing glass fragments to splash out, resulting in waste of raw materials, and also ensuring the safety of the operating environment.

[0013] Preferably, as an improvement, a discharge port is provided on the receiving disc, and a cleaning plate is provided at the bottom of the rotating disc to push the fallen cap opening out of the discharge port.

[0014] The beneficial effect is that the cleaning plate can push the fallen cap opening out of the discharge port, realize automatic cleaning, avoid waste accumulation, and improve production efficiency.

[0015] Preferably, as an improvement, the laser cutting mechanism comprises two laser emitters, and the two laser emitters are distributed in a fan shape.

[0016] The beneficial effect is that the above setting can ensure that the laser can cover the entire circumference of the glass mouth, forming a complete cutting line, avoiding the problem that only a part of the mouth of the glass is cut, resulting in incomplete and smooth subsequent cuts.

The cutting part includes a mounting seat and a laser cutting mechanism arranged on the mounting seat. A heating gun 3 is also arranged behind the laser cutting mechanism and is aligned with the lower part of the conveying frame. The laser cutting mechanism includes two laser emitters 8. The two laser emitters 8 are distributed in a fan shape to ensure that the laser can cover the entire circumference of the glass cup mouth and form a complete cutting line. The firing port of the heating gun 3 is located below the laser cutting mechanism. The laser cutting can leave a notch on the corresponding glass cup blank. The heating gun 3 is aligned with the position 1-2 cm below the notch for heating. The notch can be followed by the notch to make the cap mouth break neatly. The heating gun 3 is positioned 1-2 cm below the notch. The heating range can be accurately controlled to heat only the cap mouth, reduce the thermal impact on other parts of the glass cup blank, and avoid deformation and damage to the glass cup blank. When the rotating disk 1 drives the conveying frame to move, the conveying frame rotates itself at the same time.

[0023] A second turntable 2 is fixed on the top of the rotating disk 1, and a plurality of first sprockets are arranged around the second turntable 2. A plurality of motors are provided to drive the first sprockets to rotate. Chains 14 are tensioned on the plurality of first sprockets. The conveying frame is connected to the second sprocket 5, the connecting part 4 and the vacuum suction cup 6 for adsorbing the glass cup blank in sequence from top to bottom. A connecting ring 7 is provided to limit the conveying frame on the rotating disk 1. A shaft sleeve is provided on the inner side of the connecting ring 7. The connecting part 4 is connected to the connecting ring 7 through the shaft sleeve. The connecting part 4 and the shaft sleeve are interference fit. The shaft sleeve and the connecting ring 7 are rotatably connected. The second sprockets 5 are all meshed with the chains 14, thereby driving the conveying frame to rotate relative to the rotating disk 1. On the one hand, when the rotating disk 1 drives the glass cup blank to rotate, it is convenient for the laser cutting mechanism to perform uniform laser cutting on a circle around the glass cup blank. On the other hand, the glass cup blank can be circumferentially contacted with the heating gun 3, so that the bottom of the glass cup blank is evenly heated, so that the cap mouth can fall as a whole without causing local residue. Uniform laser cutting and heating improve the appearance quality and performance of the finished product.

[0024] A receiving tray 9 is provided at the bottom of the fixed frame, and a plurality of support plates 10 for receiving the cap openings are provided circumferentially at the bottom of the rotating disk 1. The support plates 10 are all opposite to the conveying frame. A push plate 11 is also provided obliquely on the mounting seat. The push plate 11 pushes the cap openings off the support plate 10.

The cleaning plate 12 can push the cap openings that have fallen off from the discharge port 13, thereby achieving automatic cleaning, avoiding waste accumulation, and improving production efficiency. The rotating disk 1 performs preliminary collection of the cap openings that have fallen off, and then pushes the cap openings down through the push plate 11, and collects the waste that has fallen off the cap openings in two times, thereby avoiding the cap openings from being damaged during the falling process, causing glass fragments to splash out, resulting in a waste of raw materials, and also ensuring the safety of the operating environment.

[0025] The specific implementation process is as follows:

[0026] When the conveyor frame is driven by the rotating disk 1 and is close to the laser cutting mechanism, the laser cutting mechanism performs laser cutting on the glass cup blank, leaving a mark on the glass cup blank. The conveyor frame can rotate by itself, which can ensure that the laser cutting mechanism emits laser, so that the entire cup mouth of the glass cup blank is left with a complete circular mark. After that, the heating gun 3 is aimed at the bottom of the conveyor frame to heat and circumferentially burn the mouth of the glass cup. Under the action of thermal expansion and contraction, the cap mouth automatically falls off after heating. Laser cutting and thermal expansion and contraction processing can make the cut edge of the glass cup smoother and more uniform, avoiding the problems of thick edges and glass drops caused by traditional thermal cutting. The arrangement of the conveyor frame and the rotating disk 1 enables the glass cup blank to be continuously cut and heated, greatly improving production efficiency.
