Description

Technical Field

[0001] This utility model relates to the field of quartz crucible production technology, specifically to a quartz crucible demolding device. Background Technology

[0002] Quartz crucibles are generally produced using two methods: slip casting or solidification. The slip casting process includes: slip casting, demolding, turning, curing, initial inspection, trimming, drying, calcination, edge trimming, final inspection, and packaging. The demolding process involves rotating the molten mold at a certain angle after the quartz crucible has been melted at high temperature, allowing the crucible to be pulled out of the mold, thus completing the demolding process.

[0003] The current demolding process for quartz crucibles involves one operator tapping the melting mold while another operator uses high-temperature resistant asbestos cloth to hold the rim of the quartz crucible and apply a certain pulling force to loosen it from the melting mold. The crucible then detaches from the mold under its own weight. However, due to the high temperature of the quartz crucible, direct contact with it poses a risk of burns to the operator. Furthermore, to ensure the crucible detaches from the mold under its own weight after loosening, the tilting device is typically at a certain angle. However, during operation, the operator cannot control the direction of force based on the tilt angle of the melting mold, resulting in the crucible failing to be safely pulled out.

[0004] The purpose of this invention is to provide a quartz crucible demolding device.

[0005] This utility model is implemented by the following technical solution: a quartz crucible demolding device, which includes a traveling trolley, a guide plate, a support plate, a motor, a screw, an adjusting block, a connecting rod, a clamping arm, and a clamping plate;

[0006] The guide plate is hinged to the top end face of the traveling trolley;

[0007] The top end face of the guide plate is fixed to the support plate, and the motor is fixed to one side of the support plate. The output shaft of the motor movably passes through the support plate and is fixedly connected to the screw.

[0008] The adjusting block is screwed to the outer wall of the screw, and the clamping arm is connected to both sides of the adjusting block through the connecting rod. The two ends of the connecting rod are respectively hinged to the side wall of the adjusting block and the middle of the clamping arm.

[0009] One end of the clamping arm is hinged to the side of the support plate away from the motor, and the other end of the clamping arm is fixed with a clamping plate.

[0010] Furthermore, the inner wall of the clamping piece is fixed with an anti-slip protective layer.

[0011] Furthermore, mounting grooves are respectively provided on both sides of the top end face of the traveling trolley below the guide plate.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1As shown, the quartz crucible demolding device includes a traveling trolley 1, a guide plate 2, a support plate 6, a motor 7, a screw 8, an adjusting block 9, a connecting rod 15, a clamping arm 10, and a clamping plate 11.

[0020] The top end face of the traveling trolley 1 is hinged to the guide plate 2. The top end face of the traveling trolley 1 below the guide plate 2 is provided with mounting grooves 3 on both sides. A telescopic device 4 is vertically fixed in the mounting groove 3. A universal ball 5 is fixed to the telescopic end of the telescopic device 4. The universal ball 5 rolls in contact with the bottom end face of the guide plate 2. The telescopic device 4 is any one of a cylinder, hydraulic cylinder or electric push rod. Under the action of the telescopic device 4 and the universal ball 5, the angle of the guide plate 2 is adjusted to match the tilt angle of the melting mold and ensure that the direction of the pulling force is consistent with the tilt direction of the quartz crucible.

[0021] A support plate 6 is fixed to the top end face of the guide plate 2. A motor 7 is fixed to one side of the support plate 6. The output shaft of the motor 7 passes through the support plate 6 and is fixedly connected to the screw 8. An adjusting block 9 is screwed to the outer wall of the screw 8. Clamping arms 10 are connected to both sides of the adjusting block 9 through connecting rods 15. The two ends of the connecting rods 15 are respectively hinged to the side wall of the adjusting block 9 and the middle of the clamping arm 10. One end of the clamping arm 10 is hinged to the side of the support plate 6 away from the motor 7. A clamping piece 11 is fixed to the other end of the clamping arm 10. Under the action of the motor 7, the screw 8 is driven to rotate. The screw 8 drives the adjusting block 9 to move along it, realizing the clamping and releasing operation between the two clamping arms 10.

[0022] The inner wall of the clamping plate 11 is fixed with an anti-slip protective layer 12, which provides cushioning force and effectively protects the outer wall of the quartz crucible.

[0023] A proximity switch 13 is fixed on the outer wall of the traveling trolley 1 near the clamping plate 11. An alarm light 14 is fixed on the top end face of the traveling trolley 1. The proximity switch 13 and the alarm light 14 are electrically connected. Specifically, the proximity switch 13 is connected to the alarm light 14 through a contactor to form a control circuit. The power supply can be provided by a storage battery or an external power supply.

[0024] The specific operation process of this embodiment is as follows:

[0025] The trolley 1 is pushed to move towards the turning device of the melting mold. When the proximity switch 13 senses the turning device, the proximity switch 13 is triggered, and the alarm light 14 lights up under the action of the control circuit.

[0026] The flipping device is activated to tilt the melting mold at a specific angle. The telescopic device 4 is activated and extends, causing the guide plate 2 to rotate relative to the top end face of the traveling trolley 1 to the same angle as the melting mold. The specific angle is measured using an angle measuring instrument.

[0027] When the tilt angle of the guide plate 2 is adjusted to the correct position, the telescopic device 4 stops. At this time, the clamping arms 10 are placed on both sides of the quartz crucible opening. The motor 7 is started. During the rotation of the output shaft of the motor 7, the screw 8 is driven to rotate. The adjusting block 9 on the screw 8 moves along the length of the screw 8. Through the connecting rod 15, the two clamping arms 10 are driven to move closer to each other. When the clamping plate 11 contacts the outer wall of the quartz crucible opening and clamps the quartz crucible.

[0028] Start the traveling trolley 1 (or pull the trolley manually), and apply a certain pulling force to the quartz crucible under the action of the clamping arm 10. At the same time, the operator gently taps the melting mold. Under the action of the pulling force, the quartz crucible is loosened from the melting mold. This reduces the risk of burns caused by the operator directly contacting the quartz crucible. At the same time, with the cooperation of the telescopic device 4 and the guide plate 2, it can be ensured that the clamping arm 10 and the melting mold have the same tilt angle, ensuring the consistency of the force direction and ensuring the safety of the quartz crucible during the loosening process.

[0029] Subsequently, by adjusting the angle of the flipping device and the angle of the guide plate, the quartz crucible is pulled out a certain distance. Then, other hoisting equipment is used to remove the quartz crucible from the melting mold and transport it to the designated location. This device reduces the risk of the quartz crucible falling during the pulling process.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
