Description

Technical Field

[0001] This invention relates to the field of catalyst prototyping technology, specifically to a catalyst prototyping machine. Background Technology

[0002] In chemical reactions, a catalyst is a substance that can change the rate of a chemical reaction without altering the chemical equilibrium, and whose mass and chemical properties remain unchanged before and after the reaction. It is estimated that catalysts are used in over 90% of industrial processes, such as chemical, petrochemical, biochemical, and environmental protection industries. There are many types of catalysts, which can be classified by state as liquid catalysts and solid catalysts; and by the phase of the reaction system as homogeneous catalysts and heterogeneous catalysts. Homogeneous catalysts include acid, base, soluble transition metal compounds, and peroxide catalysts. Catalysts play an extremely important role in modern chemical industry. For example, iron catalysts are used in the production of ammonia, vanadium catalysts are used in the production of sulfuric acid, and different catalysts are used in the polymerization of ethylene and the production of rubber from butadiene, the three major synthetic materials.

[0003] While existing catalyst prototyping machines can produce catalyst prototyping materials, they still have the following shortcomings: During use, catalysts of different shapes have different surface areas, resulting in different catalyst performance. In order to adapt to different reactions, catalysts of different shapes need to be produced. However, when producing catalysts of different shapes, existing prototyping machines require manual tightening and loosening of screws to change different prototyping heads. The operation process is cumbersome, consumes a lot of manpower and time, and seriously affects production efficiency.

[0004] To address this, a catalyst preform forming machine is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a catalyst preform forming machine. By setting a rotating mechanism, after the limiting sleeve separates from the forming tube, the rotating roller can drive the mounting frame to rotate, thereby facilitating the user to select a suitable forming head and producing catalysts of different shapes. Since the forming head is spirally mounted on the mounting frame, the user can replace more different forming heads, which is beneficial to the production of catalyst preforms and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A catalyst preform forming machine, comprising:

[0008] A base, on the top wall of which a drive box is fixedly installed, on the side wall of which a conveying pipe is fixedly connected, on the top wall of which a crushing box is fixedly connected and connected to the conveying pipe, and on the top wall of which a feed hopper is fixedly connected and connected to the crushing box.

[0009] A forming tube is fixedly connected to one end of a conveying pipe away from the drive box. A cleaning box is provided below the forming tube and is fixedly connected to the side wall of the base.

[0010] An electric telescopic rod is installed inside the top wall of the forming tube. A limit sleeve is fixedly connected to the other end of the electric telescopic rod. A forming head is movably installed between the end of the forming tube and the limit sleeve. A rotating mechanism for quick replacement of the forming head is provided on the bottom wall of the forming tube.

[0011] First, start the motor in the drive box. After the raw materials for making catalyst blanks are poured into the feed hopper, they are processed by the crushing box and then further enter the forming tube through the conveying pipe. Different shapes of catalyst blanks can be made through different forming heads at the end of the forming tube. The operation is simple and convenient.

[0012] Preferably, the rotating mechanism includes a rotating roller rotatably mounted on the bottom wall of the forming tube, with one end of the rotating roller extending into the cleaning tank. Four mounting brackets are evenly fixedly connected to the side wall of the rotating roller inside the cleaning tank, and the forming head is spirally mounted on the end of the mounting bracket. An opening groove that cooperates with the mounting bracket is provided on the inner wall of the bottom end of the limiting sleeve.

[0013] After the limiting sleeve separates from the forming tube, the rotating roller can drive the mounting frame to rotate, which makes it convenient for the user to select the appropriate forming head and facilitates the production of catalysts of different shapes. Since the forming head is spirally mounted on the mounting frame, the user can replace more different forming heads, which is beneficial to the production of catalyst blanks.

[0014] Preferably, a motor is installed inside the drive box, and a rotating shaft is fixedly connected to the output end of the motor. Two cooperating crushing rollers are rotatably installed inside the crushing box. One crushing roller is fixedly connected to the rotating shaft, and the other crushing roller is fixedly connected to a gear set fixedly connected to the output end of the motor. Spiral blades are provided in both the conveying pipe and the forming pipe, and one end of the spiral blades extends into the drive box. A transmission belt assembly is also fixedly connected to the output end of the motor, and the other end of the transmission belt assembly is fixedly connected to the spiral blades.

[0015] When the motor is working, it drives the crushing rollers in the crushing box to rotate through the shaft and gear set to process the raw materials. At the same time, the motor drives the spiral blades to rotate through the transmission belt set, which facilitates the injection of the crushed raw materials into the forming tube. The use of a single motor to drive the process reduces manufacturing costs and makes it convenient to use.

[0016] Preferably, a positioning mechanism is provided at the bottom end of the forming tube. The positioning mechanism includes a positioning hole opened at the bottom end of the forming tube. A second spring is fixedly connected inside the bottom wall of the positioning hole. A positioning pin is fixedly connected to the other end of the second spring. The positioning pin extends to the outside of the side wall of the forming tube. An arc groove that cooperates with the positioning pin is opened on the inner wall of the mounting bracket.

[0017] When the mounting bracket contacts the positioning pin, the positioning pin is compressed into the positioning hole. When the arc groove corresponds to the positioning pin, the second spring can push the positioning pin into the arc groove, which can indicate to the user that the forming head is in the right position. After the user continues to rotate the rotating roller, the positioning pin is further compressed into the positioning hole, making it convenient for the user to select the appropriate forming head.

[0018] Preferably, the end of the forming tube is evenly provided with a plurality of limiting holes, and the inner wall of the limiting sleeve is fixedly connected with a limiting post that mates with the limiting holes. The side wall of each limiting hole is provided with a fixing mechanism for fixing the limiting post. The fixing mechanism includes an electromagnet fixedly installed in the side wall of the limiting hole. One end of the electromagnet is fixedly connected with a spring, and the other end of the spring is fixedly connected with a limiting pin that mates with the electromagnet. The side wall of the limiting post is provided with a limiting groove that mates with the limiting pin.

[0019] When the limiting post moves into the limiting hole, the spring can push the limiting pin into the limiting groove on the limiting post, which can fix the limiting post and prevent the limiting sleeve from falling off during the molding process. This is beneficial to the stability of the molding head and further ensures the quality of catalyst molding. When the user needs to replace the molding head, the electromagnet is energized, and the electromagnet can attract the limiting pin, which can then slide out of the limiting groove, making it convenient for the user to move the limiting sleeve and facilitating the replacement of the molding head.

[0020] Preferably, the limiting pin is slidably installed in the side wall of the limiting hole, a terminal block is fixedly connected to the bottom wall of the limiting pin, and the terminal block is electrically connected to the power supply. A terminal head that cooperates with the terminal block is provided between the limiting pin and the electromagnet, and the terminal head is electrically connected to the electric telescopic rod.

[0021] When the limiting pin slides out of the limiting groove under the action of the electromagnet, the terminal on the limiting pin can contact the terminal block. Therefore, the electric telescopic rod can be energized and drive the limiting sleeve to move out of the end of the forming tube. When the electromagnet is de-energized, the spring can push the limiting pin to move outward, so that the terminal is separated from the terminal block. Thus, the electric telescopic rod can be de-energized and retracted, which is beneficial to the assembly of the limiting sleeve.

[0022] Preferably, an electric telescopic rod 2 is fixedly connected to the inner wall of the cleaning box at a position corresponding to the forming head. A cleaning frame is fixedly connected to the other end of the electric telescopic rod 2. A plurality of nozzles that cooperate with the forming holes on the forming head are evenly fixedly connected to the end of the cleaning frame, and a sponge pad is wrapped around the outside of each nozzle.

[0023] The electric telescopic rod on the cleaning rack can drive the cleaning rack to fit against the forming head, and the nozzle can clean the forming head and the forming opening on the forming head. At the same time, the sponge pad on the outer wall of the nozzle can clean the forming opening inside the forming head, which can improve the cleaning effect. The wastewater after cleaning can be discharged from the bottom of the cleaning tank for easy disposal.

[0024] Preferably, the molding tube is provided with a control assembly for controlling the operation of the electric telescopic rod II and the nozzle. The control assembly includes a connecting rod slidably installed in the side wall of the molding tube, and a cavity for the movement of the connecting rod is opened in the molding tube. One end of the connecting rod is fixedly connected to a conductive spring, and the other end of the conductive spring is fixedly connected to the side wall of the cavity. A conductive head is rotatably installed at the bottom end of the connecting rod, and the conductive head is electrically connected to a power source. A conductive plate that cooperates with the conductive head is provided in the cavity, and the conductive plate is electrically connected to the electric telescopic rod II and the nozzle switch.

[0025] When the conductive spring is energized, it immediately contracts, causing the connecting rod to move and bringing the conductive head into contact with the conductive plate. This enables the electric telescopic rod and the nozzle to start working, facilitating the cleaning of the molding head. When the conductive spring is de-energized, it extends, causing the conductive head to separate from the conductive plate and automatically shutting off the electric telescopic rod and the nozzle for easy control.

[0026] Preferably, a reduction gear is rotatably mounted on the bottom wall of the cavity, and a tooth groove that meshes with the reduction gear is fixedly connected to the bottom wall of the connecting rod.

[0027] The reduction gear can slow down the movement speed of the connecting rod, thereby allowing the conductive head to contact the conductive plate for a longer period of time, which can further extend the working time of the nozzle and facilitate the cleaning of the forming head.

[0028] Preferably, the end of the forming tube is provided with a plurality of grooves, each groove is provided with a piezoelectric ceramic sheet, and each piezoelectric ceramic sheet is electrically connected to a conductive spring. Each of the limiting sleeves is fixedly connected with a pressing rod for pressing the piezoelectric ceramic sheet.

[0029] After the head replacement is completed, disconnect the power supply to the electromagnet. At this time, the electric telescopic rod one can drive the limiting sleeve to fit against the end of the forming tube. At the same time, the pressing rod can squeeze the piezoelectric ceramic sheet in the groove once, which can make the piezoelectric ceramic sheet generate instantaneous current. Multiple piezoelectric ceramic sheets work at the same time, which can increase the current intensity and ensure that the conductive spring contracts instantly, which is beneficial to the use of the electric telescopic rod two and the nozzle.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] 1. By setting a rotating mechanism, after the limiting sleeve separates from the forming tube, the rotating roller can drive the mounting frame to rotate, which makes it convenient for users to select the appropriate forming head and facilitates the production of catalysts of different shapes. Since the forming head is spirally installed on the mounting frame, users can replace more different forming heads, which is beneficial to the production of catalyst blanks.

[0032] 2. By setting up a fixing mechanism, when the user needs to replace the molding head, the electromagnet is energized, which attracts the limiting pin, allowing the limiting pin to slide out of the limiting groove. When the limiting pin slides out of the limiting groove under the action of the electromagnet, the terminal on the limiting pin can contact the terminal block. Therefore, the electric telescopic rod can be energized and move the limiting sleeve out from the end of the molding tube, making it convenient for the user to move the limiting sleeve and facilitating the replacement of the molding head. When the electromagnet is de-energized, the spring can push the limiting pin outward, separating the terminal from the terminal block, so that the electric telescopic rod can be de-energized and retracted, which is conducive to the assembly of the limiting sleeve. When the limiting post moves into the limiting hole, the spring can push the limiting pin into the limiting groove on the limiting post, which can fix the limiting post and prevent the limiting sleeve from falling off during the molding process, which is conducive to the stability of the molding head and further ensures the quality of catalyst molding.

[0033] 3. By setting up a cleaning box, after replacing the mold head, disconnect the power supply to the electromagnet. At this time, the electric telescopic rod one can drive the limiting sleeve to fit against the end of the molding tube. At the same time, the pressing rod can squeeze the piezoelectric ceramic sheet in the groove once, which can generate an instantaneous current in the piezoelectric ceramic sheet. The simultaneous operation of multiple piezoelectric ceramic sheets can increase the current intensity and ensure that the conductive spring contracts instantly. Thus, the conductive spring can drive the connecting rod to move, which in turn allows the conductive head to contact the conductive plate. Therefore, the electric telescopic rod two and the nozzle can start working, which is convenient for cleaning the molding head. When the conductive spring is de-energized, the conductive spring can extend, which allows the conductive head to separate from the conductive plate. This allows the electric telescopic rod two and the nozzle to automatically close, which is convenient for control. The reduction gear can slow down the movement speed of the connecting rod, which allows the conductive head to contact the conductive plate for a longer period of time, further extending the working time of the nozzle, which is beneficial for cleaning the molding head and for the use of the electric telescopic rod two and the nozzle.

[0047] Please see Figures 1 to 9 This invention provides a catalyst preform forming machine, the technical solution of which is as follows:

[0048] A catalyst preform forming machine, comprising:

[0049] A base 1 is provided. A drive box 2 is fixedly installed on the top wall of the base 1. A conveying pipe 3 is fixedly connected to the side wall of the drive box 2. A crushing box 4 is fixedly connected to the top wall of the conveying pipe 3 and is connected to the conveying pipe 3. A feed hopper 5 connected to the crushing box 4 is fixedly connected to the top wall of the crushing box 4.

[0050] The forming tube 6 is fixedly connected to one end of the conveying tube 3 away from the drive box 2. A cleaning box 9 is provided below the forming tube 6 and is fixedly connected to the side wall of the base 1.

[0051] An electric telescopic rod 7 is installed inside the top wall of the forming tube 6. The other end of the electric telescopic rod 7 is fixedly connected to a limiting sleeve 8. A forming head 15 is movably installed between the end of the forming tube 6 and the limiting sleeve 8. A rotating mechanism for quickly changing the forming head 15 is provided on the bottom wall of the forming tube 6.

[0052] First, start the motor 16 in the drive box 2. After the raw materials for making catalyst blanks are poured into the feed hopper 5, they are processed by the crushing box 4 and then further enter the forming tube 6 through the conveying pipe 3. Different shapes of catalyst blanks can be made through different forming heads 15 at the end of the forming tube 6. The operation is simple and convenient.

[0053] As one embodiment of the present invention, refer to Figure 1-3 The rotating mechanism includes a rotating roller 13 rotatably mounted on the bottom wall of the forming tube 6, and one end of the rotating roller 13 extends into the cleaning tank 9. Four mounting brackets 14 are evenly fixedly connected to the side wall of the rotating roller 13 inside the cleaning tank 9, and the forming head 15 is spirally mounted on the end of the mounting bracket 14. An opening groove that cooperates with the mounting bracket 14 is opened on the inner wall of the bottom end of the limiting sleeve 8.

[0054] After the limiting sleeve 8 separates from the forming tube 6, the rotating roller 13 can drive the mounting frame 14 to rotate, which makes it convenient for the user to select the appropriate forming head 15, and facilitates the production of catalysts of different shapes. Since the forming head 15 is spirally installed on the mounting frame 14, the user can replace more different forming heads 15, which is beneficial to the production of catalyst blanks.

[0055] As one embodiment of the present invention, refer to Figure 3-4The drive box 2 is equipped with a motor 16, and the output end of the motor 16 is fixedly connected to a rotating shaft 18. Two cooperating crushing rollers 19 are rotatably installed in the crushing box 4. One crushing roller 19 is fixedly connected to the rotating shaft 18, and the other crushing roller 19 is fixedly connected to a gear set 17 fixedly connected to the output end of the motor 16. The conveying pipe 3 and the forming pipe 6 are both equipped with a spiral blade 22, and one end of the spiral blade 22 extends into the drive box 2. The output end of the motor 16 is also fixedly connected to a transmission belt set 23, and the other end of the transmission belt set 23 is fixedly connected to the spiral blade 22.

[0056] When the motor 16 is working, the motor 16 can drive the crushing roller 19 in the crushing box 4 to rotate through the rotating shaft 18 and the gear set 17 to process the raw materials. At the same time, the motor 16 can drive the spiral blade 22 to rotate through the transmission belt set 23, so that the crushed raw materials can be injected into the forming tube 6. The use of a single motor 16 can reduce the manufacturing cost and make it convenient to use.

[0057] As one embodiment of the present invention, refer to Figure 7 A positioning mechanism is provided at the bottom end of the forming tube 6. The positioning mechanism includes a positioning hole 24 opened at the bottom end of the forming tube 6. A spring 20 is fixedly connected inside the bottom wall of the positioning hole 24. A positioning pin 31 is fixedly connected to the other end of the spring 20. The positioning pin 31 extends to the outside of the side wall of the forming tube 6. A circular arc groove 32 that cooperates with the positioning pin 31 is opened on the inner wall of the mounting bracket 14.

[0058] When the mounting bracket 14 contacts the positioning pin 31, the positioning pin 31 is compressed into the positioning hole 24. When the arc groove 32 corresponds to the positioning pin 31, the spring 30 can push the positioning pin 31 into the arc groove 32, which can indicate to the user that the forming head 15 is in the right position. After the user continues to rotate the rotating roller 13, the positioning pin 31 is further compressed into the positioning hole 24, which makes it convenient for the user to select the appropriate forming head 15.

[0059] As one embodiment of the present invention, refer to Figure 5-6 The end of the forming tube 6 is evenly provided with multiple limiting holes 12, and the inner wall of the limiting sleeve 8 is fixedly connected with a limiting post that cooperates with the limiting hole 12. The side wall of the limiting hole 12 is provided with a fixing mechanism for fixing the limiting post. The fixing mechanism includes an electromagnet 25 fixedly installed in the side wall of the limiting hole 12. One end of the electromagnet 25 is fixedly connected with a spring 26, and the other end of the spring 26 is fixedly connected with a limiting pin 29 that cooperates with the electromagnet 25. The side wall of the limiting post is provided with a limiting groove that cooperates with the limiting pin 29.

[0060] When the limiting post moves into the limiting hole 12, the spring 26 can push the limiting pin 29 into the limiting groove on the limiting post, which can fix the limiting post and prevent the limiting sleeve 8 from falling off during the molding process. This is beneficial to the stability of the molding head 15 and can further ensure the quality of catalyst molding. When the user needs to replace the molding head 15, the electromagnet 25 is energized. The electromagnet 25 can attract the limiting pin 29, which can then slide out of the limiting groove, making it convenient for the user to move the limiting sleeve 8 and facilitating the replacement of the molding head 15.

[0061] As one embodiment of the present invention, refer to Figure 6 The limiting pin 29 is slidably installed in the side wall of the limiting hole 12. A terminal block 28 is fixedly connected to the bottom wall of the limiting pin 29, and the terminal block 28 is electrically connected to the power supply. A terminal head 27 that cooperates with the terminal block 28 is provided between the limiting pin 29 and the electromagnet 25, and the terminal head 27 is electrically connected to the electric telescopic rod 7.

[0062] When the limiting pin 29 slides out of the limiting groove under the action of the electromagnet 25, the terminal 27 on the limiting pin 29 can contact the terminal block 28. Therefore, the electric telescopic rod 7 can be energized and drive the limiting sleeve 8 to move out from the end of the forming tube 6. When the electromagnet 25 is de-energized, the spring 26 can push the limiting pin 29 to move outward, so that the terminal 27 separates from the terminal block 28. Thus, the electric telescopic rod 7 can be de-energized and retracted, which is beneficial to the assembly of the limiting sleeve 8.

[0063] As one embodiment of the present invention, refer to Figure 3 , 9 Electric telescopic rods 20 are fixedly connected to the inner wall of the cleaning tank 9 at positions corresponding to the forming head 15. A cleaning frame 21 is fixedly connected to the other end of each electric telescopic rod 20. Multiple nozzles 39 that cooperate with the forming holes on the forming head 15 are evenly fixedly connected to the end of the cleaning frame 21, and a sponge pad 38 is wrapped around the outside of each nozzle 39.

[0064] The electric telescopic rod 20 on the cleaning rack 21 can drive the cleaning rack 21 to fit with the molding head 15, and the nozzle 39 can clean the molding head 15 and the molding opening on the molding head 15. At the same time, the sponge pad 38 on the outer wall of the nozzle 39 can clean the molding opening inside the molding head 15, which can improve the cleaning effect. The wastewater after cleaning can be discharged from the bottom of the cleaning tank 9 for easy treatment.

[0065] As one embodiment of the present invention, refer to Figure 8The molding tube 6 is equipped with a control assembly for controlling the operation of the electric telescopic rod 20 and the nozzle 39. The control assembly includes a connecting rod 37 that is slidably installed in the side wall of the molding tube 6. A cavity for the movement of the connecting rod 37 is provided in the molding tube 6. A conductive spring 33 is fixedly connected to one end of the connecting rod 37, and the other end of the conductive spring 33 is fixedly connected to the side wall of the cavity. A conductive head 35 is rotatably installed at the bottom end of the connecting rod 37 and is electrically connected to a power source. A conductive plate 34 that cooperates with the conductive head 35 is provided in the cavity, and the conductive plate 34 is electrically connected to the switch of the electric telescopic rod 20 and the nozzle 39.

[0066] When the conductive spring 33 is energized, it immediately contracts, thereby driving the connecting rod 37 to move. This allows the conductive head 35 to come into contact with the conductive plate 34, enabling the electric telescopic rod 20 and the nozzle 39 to start working, facilitating the cleaning of the molding head 15. When the conductive spring 33 is de-energized, it extends, causing the conductive head 35 to separate from the conductive plate 34, automatically closing the electric telescopic rod 20 and the nozzle 39 for easy control.

[0067] As one embodiment of the present invention, refer to Figure 8 A reduction gear 36 is rotatably mounted on the bottom wall of the cavity, and a tooth groove that meshes with the reduction gear 36 is fixedly connected to the bottom wall of the connecting rod 37.

[0068] The reduction gear 36 can slow down the movement speed of the connecting rod 37, thereby allowing the conductive head 35 to contact the conductive plate 34 for a longer period of time, which can further extend the working time of the nozzle 39 and facilitate the cleaning of the forming head 15.

[0069] As one embodiment of the present invention, refer to Figure 5 The end of the forming tube 6 is evenly provided with multiple grooves 10, each groove 10 is provided with a piezoelectric ceramic sheet 11, and each piezoelectric ceramic sheet 11 is electrically connected to the conductive spring 33. Each inner wall of the limiting sleeve 8 is fixedly connected with a pressing rod for pressing the piezoelectric ceramic sheet 11.

[0070] After the head 15 is replaced, the power supply to the electromagnet 25 is disconnected. At this time, the electric telescopic rod 7 can drive the limiting sleeve 8 to fit against the end of the forming tube 6. At the same time, the pressing rod can squeeze the piezoelectric ceramic sheet 11 in the groove 10 once, which can make the piezoelectric ceramic sheet 11 generate instantaneous current. Multiple piezoelectric ceramic sheets 11 work at the same time, which can increase the current intensity and ensure that the conductive spring 33 contracts instantly, which is beneficial to the use of the electric telescopic rod 20 and the nozzle 39.

[0071] Working principle: First, the motor 16 in the drive box 2 is started, and the raw material for catalyst preparation is poured from the feed hopper 5 into the crushing box 4. At this time, the motor 16, through the rotating shaft 18 and the gear set 17, can drive the crushing roller 19 in the crushing box 4 to rotate, processing the raw material. At the same time, the motor 16, through the transmission belt set 23, can drive the spiral blade 22 to rotate, which can inject the crushed raw material into the forming tube 6. Driven by a single motor 16, the production cost can be reduced and the operation is convenient. When the user needs to produce catalysts of different shapes, the electromagnet 25 is energized. The electromagnet 25 can attract the limiting pin 29, thereby allowing the limiting pin 29 to slide out of the limiting groove, making it convenient for the user to move the limiting sleeve 8. When the 25th element slides out of the limiting groove, the terminal 27 on the limiting pin 29 can contact the terminal block 28, so the electric telescopic rod 7 can be energized and drive the limiting sleeve 8 to move out from the end of the forming tube 6. After the limiting sleeve 8 separates from the forming tube 6, the rotating roller 13 can drive the mounting frame 14 to rotate, which makes it convenient for the user to select the appropriate forming head 15 and facilitates the production of catalysts of different shapes. Since the forming head 15 is spirally installed on the mounting frame 14, the user can replace more different forming heads 15, which is beneficial to the production of catalyst blanks. During the replacement process, when the mounting frame 14 contacts the positioning pin 31, the positioning pin 31 is compressed into the positioning hole 24. When the arc groove 32 is opposite to the positioning pin 31, When the spring 30 is in time, it can push the positioning pin 31 into the arc groove 32, indicating to the user that the forming head 15 is in the appropriate position. After the user continues to rotate the rotating roller 13, the positioning pin 31 is further compressed into the positioning hole 24, making it convenient for the user to select the appropriate forming head 15. After the replacement is completed, the electromagnet 25 is de-energized, and the spring 26 can push the limit pin 29 outward, separating the terminal 27 from the terminal block 28. This allows the electric telescopic rod 7 to be de-energized and retracted, which is beneficial for the assembly of the limit sleeve 8. At the same time, after the limit post moves into the limit hole 12 with the limit sleeve 8, the spring 26 can push the limit pin 29 into the limit groove on the limit post, which can fix the limit post and prevent the limit sleeve 8 from coming off during the forming process. The pressing rod, when reattached to the end of the molding tube 6, can perform a single compression on the piezoelectric ceramic sheet 11 in the groove 10, causing the piezoelectric ceramic sheet 11 to generate an instantaneous current. The simultaneous operation of multiple piezoelectric ceramic sheets 11 increases the current intensity, ensuring the instantaneous contraction of the conductive spring 33. This allows the conductive spring 33 to move the connecting rod 37, enabling the conductive head 35 to contact the conductive plate 34. This allows the electric telescopic rod 20 and the nozzle 39 to begin operation, facilitating cleaning of the molding head 15. When the conductive spring 33 is de-energized, it extends, causing the conductive head 35 to separate from the conductive plate 34.The system enables the electric telescopic rod 20 and the nozzle 39 to close automatically, facilitating control. Because the reduction gear 36 slows down the movement of the connecting rod 37, the conductive head 35 can maintain contact with the conductive plate 34 for a longer period, further extending the working time of the nozzle 39. This is beneficial for cleaning the molding head 15 and for the overall use of the electric telescopic rod 20 and the nozzle 39.
