It is used for dispensing, coating, sealing and other operations in various industrial production processes. Dispensing valves are widely used in electronics, automobiles, medical equipment, aerospace and other fields, which can improve production efficiency, reduce waste and costs.

[0003] A patent document with announcement number CN211637138U has appeared in the prior art, which discloses a ceramic dispensing valve, including a cylinder sleeve, a long shaft is inserted into the interior of one end of the cylinder sleeve, a cylinder head sleeved on the long shaft is arranged on the outside of the other end of the cylinder sleeve, a nut threadedly connected to the outer wall of the long shaft is arranged on the outside of the cylinder head, a water nozzle is arranged on the outside of the end of the long shaft away from the cylinder sleeve, and a glue storage cavity is arranged between the water nozzle and the cylinder sleeve, a piston sleeved on the outside of the long shaft is arranged inside the cylinder sleeve, and the cylinder sleeve, long shaft, water nozzle, cylinder head, nut and piston are all made of ceramic materials. The patent document is made of ceramic materials, which has the advantages of high hardness, wear resistance, high temperature resistance, corrosion resistance, high corrosion resistance and good sealing performance, and has self-lubricating effect during processing, which changes the traditional sliding friction and lubrication mechanism of metal rods. The overall layout is exquisite and sealed, and it is easy to disassemble.

[0004] The above and existing technologies have the following defects: after the dispensing valve completes the dispensing operation, glue will remain in the water nozzle of the dispensing valve. When the glue cools down, it will solidify. At this time, the glue will easily clog the water nozzle, thereby affecting the normal operation of the dispensing valve.

[0005] Therefore, a ceramic dispensing valve is proposed. Utility Model Content

[0006] The utility model aims to solve the shortcoming that glue easily blocks a water nozzle, and proposes a ceramic glue dispensing valve.

[0008] The effect achieved by the above components is: by setting up a heating structure, the air around the water nozzle is heated by using an electric heating ring, thereby heating the water nozzle, thereby preventing the residual glue in the water nozzle from solidifying and clogging the water nozzle, thereby ensuring that the dispensing valve can work normally.

[0009] Preferably, the connecting rod is in the shape of a regular hexagonal prism.

[0012] The effect achieved by the above components is: the bending rod will slide along the surface of the pressure plate when following the movement of the connecting rod, the movement of the connecting rod will drive the card frame to move, and the card frame will move the electric heating ring to the bottom of the water nozzle. When the water nozzle needs to be used for dispensing glue, the output end of the motor is controlled to rotate. At this time, the spring begins to contract, and the spring will drive the connecting rod to slide upward, thereby driving the card frame to move synchronously to prevent the card frame from interfering with the normal dispensing of the water nozzle.

[0018] The effect achieved by the above components is that the collection box can collect the dripping glue.

[0019] Compared with the prior art, the advantages and positive effects of the utility model are:

[0020] In the utility model, a heating structure is provided and an electric heating ring is used to heat the air around the water nozzle, thereby heating the water nozzle, thereby preventing the glue remaining in the water nozzle from solidifying and clogging the water nozzle, thereby ensuring that the dispensing valve can work normally.

[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0028] like Figure 1-Figure 4As shown, the utility model provides a ceramic dispensing valve, including a valve housing 1, the surface of the valve housing 1 is fixed and connected with two air guide tubes 2, the inner sliding connection of the valve housing 1 is provided with a valve stem 3, the arc surface of the valve stem 3 is fixedly connected with a piston 4, the piston 4 is slidably connected to the valve housing 1, the surface of the valve housing 1 is fixedly connected with a glue storage bin 6, the glue storage bin 6 is fixedly connected with a water nozzle 5, the size of the valve stem 3 is matched with the size of the water nozzle 5, the valve housing 1, the air guide tube 2, the valve stem 3, the piston 4, the water nozzle 5 and the glue storage bin 6 are all made of ceramic material, the outer wall of the valve housing 1 is provided with a heating structure 7, the heating structure 7 includes a motor 701, the motor 701 is fixedly connected to the valve housing 1, the output end of the motor 701 is fixedly connected with a connecting pipe 702, the inner wall of the connecting pipe 702 is slidably connected with a connecting rod 703, the lower end of the connecting rod 703 is fixedly connected with a card frame 704, and the surface of the card frame 704 is fixedly connected with an electric heating ring 705.

[0029] like Figure 3 and Figure 4 As shown, the connecting rod 703 is in the form of a regular hexagonal prism structure, and the connecting rod 703 in the form of a regular hexagonal prism structure can stably rotate with the connecting pipe 702. A round rod 706 is fixedly connected to the outer wall of the valve housing 1, and a pressure plate 707 is fixedly connected to one end of the round rod 706. A bending rod 708 is fixedly connected to the surface of the connecting rod 703. A spring 709 is fixedly connected to the upper end of the connecting rod 703, and one end of the spring 709 is fixedly connected to the connecting pipe 702. When the bending rod 708 moves with the connecting rod 703, it will slide along the surface of the pressure plate 707. The movement of the connecting rod 703 will drive the clamping frame 704 to move, and the clamping frame 704 will move the electric heating ring 705 to the bottom of the water nozzle 5. When the water nozzle 5 needs to be used for dispensing glue, the output end direction of the motor 701 is controlled to rotate. At this time, the spring 709 begins to contract, and the spring 709 will drive the connecting rod 703 to slide upward, thereby driving the clamping frame 704 to move synchronously to prevent the clamping frame 704 from interfering with the normal dispensing of the water nozzle 5.

[0030] like Figure 3 and Figure 4 As shown, the pressure plate 707 has a spiral structure. Since the pressure plate 707 has a spiral structure, the bending rod 708 will drive the connecting rod 703 to move downward. Both ends of the pressure plate 707 are fixedly connected with a flat plate 710. After the bending rod 708 contacts the flat plate 710, the flat plate 710 reaches the position of limiting the bending rod 708, thereby limiting the position of the electric heating ring 705. The inner wall of the card frame 704 is slidably connected with a collecting box 711. The size of the collecting box 711 is adapted to the size of the faucet 5, and the collecting box 711 can collect dripping glue.

[0031] Its overall working principle is that the working principles among the valve housing 1, the air guide tube 2, the valve stem 3, the piston 4, the water nozzle 5 and the glue storage bin 6 are all existing public technologies and will not be described in detail here. When the dispensing valve suspends the dispensing operation, the output end of the control motor 701 rotates, and the rotation of the output end of the motor 701 will drive the connecting tube 702 to rotate, and the rotation of the connecting tube 702 will drive the connecting rod 703 to rotate. When the bending rod 708 moves with the connecting rod 703, it will slide along the surface of the pressure plate 707. Since the pressure plate 707 is a spiral structure, the bending rod 708 will drive the connecting rod 703 to move downward, and the movement of the connecting rod 703 will drive the card frame 704 to move, and the card frame 704 will move the electric heating ring 705 to the bottom of the water nozzle 5. At this time, the bending rod 708 will contact the flat plate 710, and the flat plate 710 reaches the position to limit the bending rod 708. In order to limit the position of the electric heating ring 705, the spring 709 will be stretched when the connecting rod 703 moves, and the connecting rod 703 with a regular hexagonal prism structure can stably rotate with the connecting tube 702, and then power is supplied to the electric heating ring 705, and the electric heating ring 705 can convert electrical energy into thermal energy. The electric heating ring 705 will heat the air around the water nozzle 5, thereby heating the water nozzle 5, and thus preventing the residual glue in the water nozzle 5 from solidifying and clogging the water nozzle 5. At this time, the collection box 711 can collect the dripping glue. When the water nozzle 5 needs to be used for glue dispensing, the output end of the control motor 701 is rotated in the opposite direction. At this time, the spring 709 begins to shrink, and the spring 709 will drive the connecting rod 703 to slide upward, thereby driving the card frame 704 to move synchronously, to prevent the card frame 704 from interfering with the normal glue dispensing of the water nozzle 5.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
