Description

Technical Field

[0001] The utility model relates to the field of glass cup processing equipment, in particular to automatic glass cup opening equipment with thermal explosion. Background Art

[0002] In the glass product manufacturing industry, glass bottles are widely used in food, beverage and chemical reagent packaging due to their transparent and corrosion-resistant properties. The traditional cup mouth processing method relies on manual operation, which not only requires workers to have high skills and experience to ensure the uniformity and aesthetics of the cup mouth molding, but also faces the problems of low production efficiency and uneven quality of finished products. In order to overcome these limitations, at present, the Chinese patent with application number: 201922376915.3 discloses a cup mouth processing equipment for a beaker, by setting a notch on the turntable, and setting a forming device and a heating device on the frame. The forming device includes a cutter head, a mounting rod and a lifting plate. The cutter head is fixedly mounted on the mounting rod, and the lifting plate is slidably arranged on the frame. When in use, the cup mouth is heated by the heating device, and the lifting plate drives the cutter head to extend into the cup mouth to pierce the cup mouth, so as to achieve the purpose of automatically processing the cup mouth, reduce the requirements for workers, and improve processing efficiency.

[0003] However, in actual production applications, the process of using a fixed cutter head to form a cup spout has certain limitations. Specifically, when the fixed cutter head is used to stretch and cut the glass beaker to form a cup spout, the force application point is concentrated, which may cause excessive stress on the glass locally, affecting the molding quality of the cup spout, resulting in the molded cup spout being relatively fragile and easy to break during use. Utility Model Content

[0004] The utility model aims to provide a thermal explosion automatic mouth-breaking device to improve the molding quality of the cup mouth.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an automatic mouth-breaking device for thermal explosion, including a frame and an automatic mouth-breaking mechanism, a turntable is rotatably arranged on the frame, a negative pressure conveying unit for transporting glass bottles is arranged on the turntable, the negative pressure conveying unit includes a suction cup for adsorbing glass bottles, the automatic mouth-breaking mechanism includes a reciprocating unit and a mouth-breaking unit, the reciprocating unit includes a reciprocating platform slidably arranged on the frame and capable of rotating relative to the frame, when the reciprocating platform and the turntable rotate in the same direction, the angular velocity of the reciprocating platform is equal to that of the turntable, the mouth-breaking unit includes a lifting platform and a first heating part, a reciprocating cylinder is fixed on the lifting platform, a mounting rod is fixed on the output shaft of the reciprocating cylinder, the telescopic direction of the mounting rod is the same as the radial direction of the turntable, a cutter head is rotatably arranged on the mounting rod, and the first heating part is fixed on the reciprocating platform and can heat the mouth of the glass bottle.

[0006] The beneficial effects of this solution are: 1. The mouth-breaking unit is set on a reciprocating platform with the same angular velocity as the rotation direction of the turntable. During piercing, the turntable does not need to be started intermittently, and the turntable can rotate continuously, thereby improving the piercing efficiency; 2. When switching the piercing station, it is only necessary to switch the relative position of the reciprocating platform and the turntable. The dead weight of the reciprocating platform is lighter than that of the turntable. The speed of switching the reciprocating platform has lower power requirements for the driving part than that of switching the turntable, and consumes less energy; 3. The bottle mouth is softened by the first heating part, and then the cup mouth is pierced by the rotating knife head. When the rotating knife head contacts the glass, it can complete the molding process more smoothly through continuous sliding action rather than a single cutting or squeezing action, thereby reducing damage to the glass surface and improving the quality of the finished product.

[0007] Furthermore, it also includes a heat preservation unit corresponding to the negative pressure delivery unit, the heat preservation unit includes a heat preservation cylinder, the heat preservation cylinder is formed by two semi-cylinders spliced ​​together, and the two semi-cylinders are hinged on the turntable.

[0008] Beneficial effect: After the mouth is broken, the two semi-cylinders are closed and spliced ​​into an insulation barrel, which slows down the cooling speed, gradually releases the stress inside the glass, reaches a stress equilibrium state, and improves the strength.

[0009] Furthermore, the heat preservation unit also includes a second heating part, and the second heating part is fixedly arranged on the turntable.

[0010] Beneficial effect: further reduce the cooling speed of the glass bottle, gradually release the stress inside the glass, achieve stress equilibrium state, and improve strength.

[0011] Furthermore, the reciprocating unit also includes a driving gear rotatably arranged on the frame and a servo motor driving the driving gear to reciprocate. An arc-shaped rack concentric with the turntable is fixedly arranged on the reciprocating platform, and the driving gear meshes with the arc-shaped rack.

[0012] Beneficial effect: The servo motor drives the active gear to rotate, and the active gear drives the arc rack to rotate, thereby driving the reciprocating platform to reciprocate

[0013] Furthermore, an arc-shaped slide groove is arranged on the frame, and an arc-shaped slider is arranged on the reciprocating platform. Both the arc-shaped slider and the arc-shaped slide groove are concentric with the turntable.

[0014] Beneficial effects: The sliding track of the reciprocating platform is restricted by the slide groove and the slider, the structure is simple and the reliability is high.

[0015] Furthermore, a supporting portion for supporting the mounting rod is fixed on the lifting platform.

[0016] Beneficial effects: avoiding bending of the mounting rod, limiting the expansion and contraction direction of the mounting rod to the radial direction, and improving the molding quality.

[0017] Furthermore, the negative pressure delivery unit also includes a negative pressure generating part and a telescopic rod that can generate negative pressure. The negative pressure generating part is fixed on the turntable, the telescopic rod is slidably set on the turntable, and the suction cup is fixed at one end of the telescopic rod and is connected to the negative pressure generating part through the telescopic rod.

[0018] Furthermore, it also includes a connecting hose, and the negative pressure generating part is connected with the telescopic rod through the connecting hose.

[0019] Beneficial effect: the negative pressure generating part is arranged on the turntable, and the telescopic rod is connected to the negative pressure generating part through a connecting hose, and the position of the suction cup can be raised or lowered by the telescopic rod, so that the suction cup can adapt to the transportation of glass bottles of different heights.
