The upper end of the rotating mechanism 21 is fixedly connected to the sand box 1, one side of the rotating mechanism 21 is arranged parallel to the external furnace, and the other side of the rotating mechanism 21 is slidably connected to the lifting mechanism 22. The lower end of the lifting mechanism 22 is slidably connected to the lower frame device 3. One side of the lower end of the lower frame device 3 is fixedly connected to the positioning device 4, and the other side is fixedly provided with a controller 5. The rotating mechanism 21, the lifting mechanism 22 and the lower frame device 3 are all connected to the controller 5 by signal. The equipment has a positioning device, which can be accurately positioned with the quartz crucible furnace equipment mechanism. The main frame is composed of profiles, which is light as a whole, simple in structure, concise in function and easy to understand in operation. The equipment can reduce the loss caused by human operation factors. The equipment adopts a new design concept and has the characteristics of high precision, reliability, stability, etc., which helps users control product quality and reduce costs.

[0036] The rotating mechanism 21 includes a rotating frame 211, a rotating assembly 212 and a No. 1 motor 213. One side of the rotating frame 211 is slidably connected to the lifting mechanism 22, and the other side is provided with a rotating assembly 212. A No. 1 motor 213 is fixedly arranged at the connection between the rotating frame 211 and the rotating assembly 212. The output shaft of the No. 1 motor 213 is fixedly connected to the rotating assembly 212. The No. 1 motor 213 is connected to the controller 5 via a driver signal. In actual use, the No. 1 motor 213 can drive the rotating assembly 212 to rotate to evenly spread quartz sand on the inner wall of the furnace. The operation is simple and convenient, and it is easy for the staff to quickly get started.

[0037] The rotating frame 211 includes a No. 1 frame 2111, a No. 2 frame 2112, a lifting frame 2113, a linear slide 2115 and two No. 1 fixed frames 2114. The No. 1 frame 2111 and the No. 2 frame 2112 are arranged parallel to each other. One end of the No. 1 frame 2111 and the No. 2 frame 2112 is fixedly connected to the No. 1 motor 213, and the No. 1 motor 213 is located between the No. 1 frame 2111 and the No. 2 frame 2112. The other ends of the No. 1 frame 2111 and the No. 2 frame 2112 are respectively connected to a No. 1 fixed frame 214. The frame 2114 is fixed to both sides of the lifting frame 2113.

A No. 1 linear slider 2116 is respectively provided at the four corners of the linear skateboard 2115. The linear skateboard 2115 is slidably connected to the lifting mechanism 22 through the No. 1 linear slider 2116. The lifting mechanism 22 can drive the rotating assembly 212 to move up and down by driving the rotating frame 211 according to the actual required height of the furnace, thereby increasing the practicality of the overall equipment.

[0038] The rotating assembly 212 includes a second fixing frame 2121, an upper sand main board 2122, a PP tube 2123, a rotating shaft 2124 and a rotating disk 2125. One side of the second fixing frame 2121 is fixedly connected to the upper sand main board 2122. The tops of the second fixing frame 2121 and the upper sand main board 2122 are fixedly connected between the first frame 2111 and the second frame 2112. The inside of the second fixing frame 2121 is respectively sleeved with a PP tube 2123 and a rotating shaft 2124. The PP tube 2123 and the rotating shaft 2124 are arranged parallel to each other. The top of the tube 2123 is connected to the sand box 1, the top of the rotating shaft 2124 is fixedly connected to the output shaft of the No. 1 motor 213, and the bottom of the rotating shaft 2124 is fixedly connected to the rotating disk 2125. In actual use, the staff puts the quartz sand into the sand box 1 in advance. Because the top of the PP tube 2123 is connected to the sand box 1, the quartz sand in the sand box 1 relies on gravity to fall through the PP tube 2123 and guide it to fall onto the rotating disk 2125, so that the quartz sand on the rotating disk 2125 is centrifugally thrown onto the inner wall of the furnace when the rotating shaft 2124 rotates.

[0039] The lifting mechanism 22 includes a No. 3 frame 221, a No. 4 frame 222, a No. 1 lead screw 223, a No. 1 drag chain 224, a No. 2 motor 225 and a No. 1 reducer 226.

The speed of the No. 2 motor 225 can be adjusted by the No. 1 reducer 226. The No. 1 drag chain 224 can roll up and down when the lifting mechanism 22 moves up and down, thereby driving the wires related to the lifting mechanism 22 to move up and down to prevent the wires from being damaged or entangled.

[0040] The fourth frame 222 includes a frame body 2221 and four No. 2 linear sliders 2222. The frame body 2221 is a rectangular structure. One side of the top of the frame body 2221 is fixedly connected to one end of the No. 3 frame 221. A No. 2 linear slider 2222 is respectively provided at the four corners of the bottom of the frame body 2221. The frame body 2221 is slidably connected to the lower frame device 3 through the No. 2 linear slider 2222. The fourth frame 222 can drive the rotating assembly 212 to slide left and right by sliding on the lower frame device 3 according to the actual required angle of the furnace, which further increases the practicality of the overall equipment and is easy to operate.

[0041] The lower frame device 3 includes a fifth frame 31, a sixth frame 32, a third motor 33, a second reducer 34, a second lead screw 35, a second drag chain 36 and a power distribution cabinet 37. The fifth frame 31 is a rectangular parallelepiped structure. The power distribution cabinet 37 and the controller 5 are fixed on one side of the fifth frame 31. The top of the fifth frame 31 is slidably connected to the frame body 2221. A second drag chain 36 is fixed on one side of the top of the fifth frame 31. The middle part of the top of the fifth frame 31 is fixedly connected to the third motor 33. The output shaft of the third motor 33 is fixedly connected to the input end of the second reducer 34. The output end of the second reducer 34 is fixedly connected to the second lead screw 35 through a coupling. The second lead screw 35 is also fixedly connected to the input end of the second reducer 34. One end is rotatably sleeved on the No. 5 frame 31, and the No. 2 lead screw 35 and the No. 2 drag chain 36 are arranged parallel to each other.

The speed of the No. 3 motor 33 can be adjusted by the No. 2 reducer 34. The function of the No. 2 drag chain 36 is the same as that of the No. 1 drag chain 224. The No. 2 drag chain 36 can roll when the lower frame device 3 drives the upper frame device 2 to move left and right, thereby driving the wires related to the lower frame device 3 to move up and down to prevent the wires from being damaged or entangled.

[0042] A walking wheel 321 is respectively provided at the four corners of the bottom of the No. 6 frame 32, and a limiting column 322 is provided on the side of the No. 6 frame 32 close to the positioning device 4. The limiting column 322 can play a limiting role when positioning with the furnace. Specifically, when the equipment moves to a distance of 1 to 2 cm from the furnace wall (crucibles of different sizes stay in different positions), the limiting column 322 is against the outer wall of the furnace to prevent the equipment from further approaching the furnace wall, and the walking wheel 321 facilitates the staff to push the entire equipment to move.

[0043] The positioning device 4 includes a No. 1 positioning rod 41 and a No. 2 positioning rod 42 which have the same structure and are arranged parallel to each other. The No. 1 positioning rod 41 includes a positioning rod body 411 and an anti-wear block 412. One end of the positioning rod body 411 is fixedly connected to the No. 6 frame 32, and the other end is fixedly provided with an anti-wear block 412. The anti-wear block 412 is made of PP material. Under actual working conditions, the quartz crucible needs to be moved due to production problems. The staff can clamp the gap between the No. 1 positioning rod 41 and the No. 2 positioning rod 42 with the origin on the moved crucible to achieve the positioning effect, and the anti-wear block 412 can reduce the friction between the positioning device 4 and the crucible when moving.

[0044] The controller 5 is a PLC, and the controller 5 is provided with a display screen 51 (the controller 5 stores different data for crucibles of different sizes). A switch button 511, an emergency stop button 512 and a reset button 513 are arranged above the display screen 51. The controller 5 is also externally connected to a button box by signal. The switch button 511 is used to control the opening and closing of the entire device. The emergency stop button 512 can stop all operating instructions in an emergency when a problem occurs in the device. The reset button 513 can return the lifting device and the transverse moving device to the origin. The button box can be used for manual simple operation of ascending, descending, system resetting and other instructions. The model of the controller 5 is fpxh-c30t. The first motor 213, the second motor 225 and the third motor 33 are all servo motors. The models of the first motor 213, the second motor 225 and the third motor 33 are all mz401n5ln07. The models of the first reducer 226 and the second reducer 34 are all pf60l1-5-p2-s2-14-30-50-70-m5.

[0045] The working principle of a semi-automatic crucible sand loading equipment:

[0046] In actual use (when there is no need to lift or move the equipment horizontally, it is assumed that the lifting and moving operations of the equipment are divided into the X-axis and the Z-axis, the Z-axis is parallel to the No. 1 lead screw 223, the X-axis is parallel to the No. 2 lead screw 35, and the equipment has scale points when moving on the X-axis and the Z-axis), the staff puts the quartz sand into the sand box 1 in advance, and the quartz sand falls on the rotating disk 2125 through the PP tube 2123 in the sand box 1 by gravity. The staff then manually starts the controller 5, and the controller 5 controls the No. 1 motor 213 to start working. The output shaft of the No. 1 motor 213 rotates to drive the rotating shaft 2124 to rotate (the rotation speed of the output shaft of the No. 1 motor 213 can be adjusted according to actual needs), and the rotation of the rotating shaft 2124 drives the rotating disk 2125 to rotate. The rotating disk 2125 rotates at a high speed and uses centrifugal force to throw the quartz sand onto the external furnace wall;

[0047] When the furnace needs to be lifted when loading, the staff manually starts the controller 5, and the controller 5 controls the No. 2 motor 225, the No. 1 reducer 226, and the No. 1 motor 213 to start working (the speed of the No. 2 motor 225 can be adjusted by the No. 1 reducer 226 according to actual needs), the output shaft of the No. 2 motor 225 rotates to drive the output shaft of the No. 1 reducer 226 to rotate, the output shaft of the No. 1 reducer 226 rotates to drive the No. 1 lead screw nut to move up and down on the No. 1 lead screw 223, the No. 1 lead screw nut moves up and down to drive the rotating mechanism 21 to move up and down, the rotating mechanism 21 moves up and down to drive the rotating shaft 2124 to move up and down, and at the same time, the No. 1 motor 213 repeats the action instructions when no lifting or lateral movement of the equipment is required;

[0048] When the furnace needs to be loaded with materials and the equipment needs to be moved horizontally, the staff manually starts the controller 5, and the controller 5 controls the No. 3 motor 33, the No. 2 reducer 34, and the No. 1 motor 213 to start working (the speed of the No. 3 motor 33 can be adjusted through the No. 2 reducer 34 according to actual needs). The output shaft of the No. 3 motor 33 rotates to drive the output shaft of the No. 2 reducer 34 to rotate. The output shaft of the No. 2 reducer 34 rotates to drive the No. 2 lead screw nut to move left and right on the No. 2 lead screw 35. The left and right movement of the No. 2 lead screw nut drives the rotating mechanism 21 to move left and right. The left and right movement of the rotating mechanism 21 drives the rotating shaft 2124 to move left and right. At the same time, the No. 1 motor 213 repeats the action instructions when no lifting or horizontal movement of the equipment is required.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
