Description

Technical Field

[0001] The utility model relates to the technical field of glass production, in particular to a spout pinching device for glass production. Background Art

[0002] A glass cup refers to a cup made of glass, usually made of raw material borosilicate glass through high-temperature firing. During the glass cup production process, the opening of the formed glass cup needs to be pinched into different shapes in order to pinch out a spout that is convenient for pouring water.

[0003] A Chinese patent with publication number CN115304255A discloses an automatic pinching machine and a burning and pinching integrated machine for glass cup production, including a base and a turntable component. A second cylinder is installed on one side of the base, and a shielding frame is installed at the telescopic end of the second cylinder. A pinching frame bracket is installed on the top of the shielding frame support seat, and a first cylinder is connected to the bottom of the pinching frame bracket. A pinching component is installed at the telescopic end of the first cylinder. Two groups of flame-spraying components are installed on the side of the base away from the shielding frame support seat. The present invention can automatically perform targeted local burning and continuous automatic pinching operations.

[0004] Since different batches of different types of cups require different curvatures of the spouts, the existing spout pinching device is inconvenient to adjust the curvature of the spout, resulting in the inability to accurately control the curvature of the spout of the glass cup, thereby affecting the pinching effect of the glass cup and failing to meet the curvature requirements of the spouts of different types of cups. Therefore, to address the above problems, a spout pinching device for glass cup production is proposed. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve the problems raised by the above-mentioned background technology, the present invention provides a spout pinching device for producing glass cups.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: a pinching device for producing glass cups described in the present invention comprises a base; a slide rail is fixedly connected to the base, a sliding sleeve is sleeved on the slide rail, a first pneumatic cylinder is installed on the side wall of the base, an active end of the first pneumatic cylinder is equipped with a first pneumatic rod, the other end of the first pneumatic rod is fixedly connected to the sliding sleeve, a fixing frame is fixedly connected to the top of the fixing frame, a first motor is installed on the top of the fixing frame, a threaded rod is connected to the output end of the first motor, a lifting plate is sleeved on the threaded rod, a guide rod is fixed in the fixing frame, and the guide rod passes through the lifting plate, an angle ruler is fixedly connected to the side wall of the lifting plate, and an arc-shaped limiting groove is provided on the angle ruler, A sliding rod is provided in the arc-shaped limit groove, one end of the sliding rod is fixedly connected to the first electrode plate, and the other end of the sliding rod is sleeved with a locking nut. When the curvature of the pinching nozzle is adjusted, the sliding rod is moved along the arc-shaped limit groove, and the first electrode plate is also moved accordingly, until the first electrode plate moves to a point where the angular distance between the first electrode plate and the initial position of the second electrode plate meets the required curvature of the pinching nozzle. The sliding rod can be fixed by the locking nut, so that the position of the first electrode plate can be adjusted, that is, the angular distance between the initial positions of the first electrode plate and the second electrode plate can be adjusted, so that the curvature of the pinching nozzle of the glass cup can be adjusted according to needs, which is convenient for subsequent precise control of the curvature of the pinching nozzle of the glass cup, thereby improving the effect of pinching nozzle.

[0007] The cam is secured to the bottom of the L-shaped plate and has a pivotal portion for securing the cam to the bottom of the L-shaped plate. When the two clamping plates move to the bottom of the cup, the first motor is operated to rotate the threaded rod, and with the cooperation of the guide rod, the lifting plate drives the clamping plate to move vertically upward until the two clamping plates move to the inner and outer sides of the cup opening respectively. The third motor is operated to rotate the bidirectional screw rod, so that the two clamping plates are close to each other, so that the position of the cup heated by the spray fire can be clamped and limited. Then the second motor is operated to drive the rotating shaft to rotate the L-shaped swing plate, so that the L-shaped swing plate can drive the pinching nozzle assembly to rotate stably until the L-shaped swing plate drives the second electrode plate to contact the first electrode plate. The warning light is powered on and lights up, so as to remind the operator to stop the pinching nozzle operation in time. While pinching the cup, the curvature of the pinching nozzle can be accurately controlled, so as to meet the curvature requirements of the pinching nozzles of different types and batches of cups.

[0008] The top end of the fixing post is fixedly connected to a plurality of support plates, and the top end of the fixing post is fixedly connected to a plurality of support plates, and a second pneumatic cylinder is installed on each support plate, and the active end of the second pneumatic cylinder is equipped with a second pneumatic rod, and the bottom end of the second pneumatic rod is fixedly connected to a pressing plate, and the pressing plate is arranged just above the U-shaped placing plate. Before pinching the mouth, the cup needs to be clamped and fixed. First, the glass is inverted on the U-shaped placing plate and its outer peripheral side is in conflict with the two interference rods. Then, the second pneumatic cylinder is operated to make the second pneumatic rod drive the pressing plate to move vertically downward until it contacts the glass, so that the cup can be pressed and limited to avoid the cup from deflecting during the pinching process.

[0009] Preferably, a fourth motor is installed on the base, and a driving gear is installed on the output end of the fourth motor, and the driving gear and the driven gear are engaged with each other. After the cup is pressed and fixed, when pinching the mouth, the fourth motor is operated, which can make the driving gear drive the driven gear to rotate, and then make the cup after clamping and limiting rotate, so that continuous automatic pinching can be performed, which greatly improves the efficiency of pinching the mouth.

[0010] Preferably, a bracket is fixedly connected to the side wall of the support frame, and a flamethrower is installed on the bracket. When pinching the spout, the flamethrower can be used to heat the spout of the cup at high temperature, which is convenient for subsequent plasticization of the cup spout.

[0011] The utility model is beneficial in that:

[0012] 1. When adjusting the curvature of the pinching spout of the present invention, the slide bar is moved along the arc-shaped limiting groove, thereby causing the first electrode plate to move accordingly, until the angular distance between the first electrode plate and the initial position of the second electrode plate meets the required curvature of the pinching spout. The slide bar can be fixed by the locking nut, thereby adjusting the position of the first electrode plate, that is, adjusting the angular distance between the initial positions of the first electrode plate and the second electrode plate. This allows the curvature of the pinching spout of the glass to be adjusted as required, facilitating subsequent precise control of the curvature of the pinching spout of the glass, thereby improving the pinching effect.

[0013] 2. In the present invention, after the position adjustment of the first electrode plate is completed, when pinching the mouth, the first pneumatic cylinder is operated to cause the first pneumatic rod to drive the sliding sleeve to move along the slide rail. When the two clamping plates move to the bottom of the cup, the first motor is operated to rotate the threaded rod. With the cooperation of the guide rod, the lifting plate drives the clamping plates to move vertically upward until the two clamping plates move to the inner and outer sides of the cup opening respectively. Then, the third motor is operated to rotate the bidirectional screw rod, thereby bringing the two clamping plates closer to each other, thereby clamping and limiting the position of the cup after the flame is heated. Then, the second motor is operated to cause the rotating shaft to rotate the L-shaped swing plate, thereby enabling the L-shaped swing plate to drive the pinching mouth assembly to rotate stably until the L-shaped swing plate drives the second electrode plate to rotate and contact the first electrode plate. At this time, the warning light is energized and illuminates, thereby promptly reminding the operator to stop pinching the mouth. Therefore, the cup pinching operation can be performed while the curvature of the pinching mouth can be accurately controlled, thereby meeting the curvature requirements of the pinching mouths of different types and batches of cups.

[0029] Working principle: Since different batches of different types of cups require different curvatures of the pinching spout, the existing pinching spout device is inconvenient to adjust the curvature of the pinching spout, resulting in the inability to accurately control the curvature of the pinching spout of the glass cup, thereby affecting the pinching effect of the glass cup and failing to meet the curvature requirements of the pinching spouts of different types of cups. Therefore, in order to solve the above problems, a pinching spout device for glass cup production is proposed. When adjusting the curvature of the pinching spout, the slide bar 11 is moved along the arc-shaped limiting groove 10, and then the first electrode plate 12 is also moved accordingly, until the first electrode plate 12 moves to the angle distance between the initial position of the second electrode plate 19 to meet the required curvature requirement of the pinching spout.

The first motor 5 is operated to rotate the threaded rod 6. With the cooperation of the guide rod 7, the lifting plate 8 drives the clamping plate 25 to move vertically upward until the two clamping plates 25 move to the inner and outer sides of the cup opening respectively. The third motor 22 is operated to rotate the bidirectional screw rod 23, and then the two clamping plates 25 are brought close to each other, so that the position of the cup after the flame heating can be clamped and limited. Then the second motor 15 is operated to make the rotating shaft 1 6 drives the L-shaped swing plate 17 to rotate. With the cooperation of the limit rod 18, the L-shaped swing plate 17 can drive the pinching spout assembly to rotate stably until the L-shaped swing plate 17 drives the second electrode plate 19 to rotate and contact the first electrode plate 12. The warning light 14 is energized and illuminated, thereby timely reminding the operator to stop the pinching operation. Therefore, while pinching the cup, the curvature of the pinching spout can be accurately controlled, thereby meeting the curvature requirements of the pinching spouts of different types and batches of cups. At the same time, through the operation of the fourth motor 39, the driving gear 40 can drive the driven gear 38 to rotate, thereby rotating the cup after clamping and limiting, thereby enabling continuous automatic pinching operation, greatly improving the efficiency of pinching.
