Description

Technical Field

[0001] The present invention relates to the technical field of glass handicrafts, and particularly to a glass handicraft melting and processing and forming device. Background Art

[0002] The glass rod material is the main production material for making glass crystal handicrafts. The main components of the rod material are quartz sand, boron, silicon, etc., and it is also called high borosilicate rod material. When manufacturing glass crystal handicrafts, the glass rod material needs to be heated to an extremely high temperature with oxy-gas to soften one end of the glass rod material and reach a temperature at which it can be shaped. Currently, most are heated to softening by hand using a horizontal burner, such as the Chinese patent document: CN202021398680.4 discloses an auxiliary tooling for manufacturing hand-made glass handicrafts, including a horizontal plate. On one side of the top of the horizontal plate, a mounting frame is fixedly installed. On the other side of the top of the mounting frame, a fixed frame is fixedly installed. On one side of the bottom of the horizontal plate, a storage bin is fixedly installed. On one side inside the storage bin, a servo motor is fixedly installed. On one side of the servo motor, a motor controller is fixedly installed. The output end of the servo motor is equipped with an input shaft. On the top of the input shaft, a vertical transmission box is fixedly installed. One side of the vertical transmission box is connected to the mounting frame through an output shaft. One end of the output shaft is provided with a clamping block. This utility model can effectively rotate the glass through the combination of the vertical transmission box and the mounting frame, thus facilitating the staff to shape the glass. However, this method has limitations. The length of the melted glass rod material is very short and cannot reach the volume of molten glass required for making larger glass crystal handicrafts. Because the horizontal firing temperature is too high, the molten glass slurry of the melted part will drip down. At the same time, if the diameter of the glass rod material is too large, the molten glass slurry on the outer circle will also drip while the glass rod material in the inner circle has not softened, and it is impossible to meet the manufacturing requirements of glass crystal handicrafts with large-capacity submissions. For this reason, there is another glass rod material burner on the market, which uses high-temperature vertical downward firing. However, when the glass rod material is melted to a certain temperature, that is, when the glass rod material reaches the melting temperature, the glass slurry will flow down. There is also a problem that if the diameter of the glass rod material is too large, the molten glass slurry on the outer circle will drip while the glass rod material in the inner circle has not softened, and it is impossible to quickly melt and process the volume of glass slurry required for making glass crystal handicrafts with a large-capacity volume. For the manufacturing of glass crystal handicrafts with a large-capacity volume, there are also large-scale devices on the market. The large-scale devices directly put all the glass rod materials into the furnace for melting and then release the glass slurry into the forming mold according to the demand of the glass crystal handicrafts to be cast into glass handicrafts. However, when the furnace of this large-scale device is in production use, it needs to be kept open for 24 hours a day. Otherwise, there is a hidden danger of furnace explosion due to the accumulation of pressure and heat in the furnace. If production is to be stopped, it will cost a lot to gradually cool down and stop the furnace. It also requires a lot of cost for furnace shutdown and re-warming when it is out of production. Maintaining continuous production of the equipment also requires a lot of cost. It is only suitable for mass production of products, and it is impossible to achieve fast and low-cost free production. Moreover, the equipment investment cost is too high. At the same time, it occupies a large space on the site and is not suitable for small and medium-sized enterprises to purchase and use. Summary of the Invention

[0003] Therefore, in view of the above problems, the present invention provides a glass handicraft melting and processing and forming device that can automatically melt glass rod materials to make glass crystal handicrafts, can be freely produced without cost waste, has a super-large melting volume capacity for glass rod materials, can quickly complete the melting and processing of a large-volume capacity glass, and has a good glass melting processing effect.

[0004] To solve this technical problem, the present invention adopts the following solutions: A glass handicraft melting and processing and forming device includes a controller, a frame, a support table, a cutting mechanism, and a forming mold. It also includes a first driving mechanism, a rotating shaft, a feeding chute, a feeding mechanism, and a melting and heating mechanism. The rotating shaft is fixedly arranged on the support table, and both ends of the rotating shaft protrude from the support table and are rotatably arranged on the frame. The first driving mechanism is arranged on the frame, and the output end of the first driving mechanism is connected to one end of the rotating shaft to drive the rotating shaft to rotate forward and backward. The melting and heating mechanism includes a furnace body, a heating unit, a clamping unit, and a rotating unit. The furnace body penetrates through the support table, and both the upper and lower ends of the furnace body protrude from the support table. The bottom of the furnace body is provided with a feeding port, and the top of the furnace body is provided with a discharging port. The heating nozzle of the heating unit penetrates into the furnace body to heat and melt the glass rod material. The clamping unit is rotatably arranged below the feeding port at the bottom of the furnace body to clamp or release the glass rod material. The rotating unit is arranged on the support table, and the rotating unit is connected to the clamping unit to drive the clamping unit to rotate below the feeding port of the furnace body, thereby driving the clamped glass rod material to rotate. The feeding chute is arranged below the support table and is located below the discharging port of the furnace body after the support table rotates to receive the melted glass rod material and send it into the forming mold to be cast into a glass handicraft. An opening is provided on the side wall of the furnace body for the cutter of the cutting mechanism to extend into the furnace body for cutting. The cutting mechanism is arranged on the support table, and the cutter of the cutting mechanism can extend into the furnace body to cut off the melted part of the glass rod material to the required capacity. The feeding mechanism includes a second driving mechanism and a material placing chute. The second driving mechanism is arranged on the support table, and the output end of the second driving mechanism drives the material placing chute located below the feeding port at the bottom of the furnace body to move up and down, thereby driving the glass rod material on the material placing chute to pass through the clamping unit and extend into the furnace body for heating and melting. The cutting mechanism, the forming mold, the first driving mechanism, the feeding mechanism, and the melting and heating mechanism are all connected and controlled by the controller.

[0005] Furthermore, a heat-resistant punch is provided on the frame that can extend into the discharging port of the furnace body to impact the softened end of the glass rod material in the furnace body to expand the softened and spread volume at the top of the glass rod material or lift it away from the discharging port of the furnace body.

[0006] Furthermore, the second driving mechanism includes two driving units. The two driving units are respectively arranged on both sides of the support table. Both sides of the material placing chute respectively extend outward to form two side support rods. The output ends of the two driving units are respectively connected to the free ends of the two side support rods of the material placing chute to drive the material placing chute to move up and down stably in the vertical direction.

[0007] Further, the driving unit is a lead screw motor.

[0008] Further, the rotating unit includes a servo motor and a synchronous belt. The clamping unit includes a rotating seat with a through hole in the middle and a hydraulic clamping mechanism arranged on the rotating seat. The clamping center of the hydraulic clamping mechanism is coaxial with the through hole of the rotating seat. The servo motor is arranged on the support platform, and the servo motor drives the rotating seat to rotate through the synchronous belt, thereby driving the glass rod material clamped by the hydraulic clamping mechanism to rotate.

[0009] Further, the controller is a PLC controller or a CNC controller.

[0010] By adopting the foregoing technical solution, the beneficial effects of the present invention are as follows: By providing a rotatable support platform, the furnace body can be turned over up and down. The feeding mechanism vertically raises glass rods and other glass rod materials into the furnace body, and the clamping unit clamps the glass rods and other glass rod materials. Driven by the rotating unit, the glass rods and other glass rod materials rotate vertically, so that the heating unit heats and melts the rotating glass rods and other glass rod materials while rotating. When heating and melting, the glass rods and other glass rod materials are vertically placed, so that the molten glass rods and other glass rod materials at the top gradually form a mushroom head without dripping. Furthermore, the molten glass rods and other glass rod materials can reach the required capacity for prefabricating glass handicrafts. When the glass rods and other glass rod materials are melted to the required capacity, the first driving mechanism drives the rotating shaft to rotate, thereby driving the entire support platform to turn over 180° up and down. The cutter of the cutting mechanism is inserted into the furnace body to cut off the molten part of the glass rod material melted to the required capacity, so that the molten glass rod material falls from the discharge port of the furnace body into the blanking chute. The blanking chute receives the molten glass rod material and sends it into the forming mold to be cast into a glass handicraft. Then, the support platform is turned back to its original position in the reverse direction for heating and melting the glass rod material required for the next handicraft. The entire machine can automatically melt glass to make glass handicrafts, the melting capacity of the glass rod material is extremely large, the large-capacity glass is quickly melted and processed, the glass melting processing effect is good, breaking the limit of the existing auxiliary melting machine for melting glass rod materials, it can be freely produced without causing cost waste, and can be used at any time according to needs. The construction cost is greatly reduced, and compared with large equipment, the overall occupied space is small and it is flexible to use; Through further setting, that is, a heat-resistant punch that can extend into the discharge port of the furnace body to impact the softened end of the glass rod material in the furnace body to expand the volume of the softened and spread top of the glass rod material or lift it away from the discharge port of the furnace body is also provided on the frame, so that the softened end of the glass rod material is thicker and has a larger volume, so that the volume of the molten slurry of the glass rod material becomes larger without dripping, so as to reach the required volume capacity of the glass rod material for larger-volume glass crystal handicrafts, further improving the volume capacity of the molten glass rod material and meeting the needs of users. The second driving mechanism uses two output ends of the driving units arranged on both sides of the support platform to be connected to the free ends of the support rods on both sides of the blanking chute to drive the blanking chute to lift smoothly in the vertical direction, so that it can continue to feed smoothly when the support platform is turned back to its original position in the reverse direction, making it more convenient to use and can be widely promoted and applied.
