Description

Technical Field

[0001] This utility model relates to the field of kneading machine equipment technology, and more specifically, to a lid-opening mechanism for a kneading machine. Background Technology

[0002] A kneader is a device used for kneading, mixing, and polymerizing high-viscosity, elasto-plastic materials. It is widely used in industries such as plastics, rubber, pharmaceuticals, and food. During the use of a kneader, the cylinder cover needs to be frequently opened for feeding, cleaning, or maintenance.

[0003] Currently, the common kneader opening mechanisms on the market are mainly divided into manual and simple hydraulic types. Manual opening mechanisms require operators to manually open the cylinder cover using tools such as wrenches and cranks. This is not only labor-intensive and inefficient, but also makes it difficult to ensure the stability of the cylinder cover opening process. Uneven force can easily cause the cylinder cover to tilt or collide with the cylinder body, resulting in equipment damage. While simple hydraulic opening mechanisms achieve a certain degree of automation, the hydraulic system has a complex structure, high maintenance costs, and is prone to hydraulic oil leakage, which not only pollutes the environment but also affects the normal operation of the equipment. Furthermore, its guide structure design is unreasonable, making it prone to jamming and deviation during cylinder cover lifting and lowering, and its sealing performance is poor, easily leading to material leakage problems during kneader operation. In addition, existing mechanisms have three major drawbacks: first, the cylinder cover lifting speed is fixed and cannot be adjusted according to the internal cylinder pressure, easily leading to material splashing or low opening efficiency; second, there is a lack of sealing status monitoring, and the aging of the sealing strip cannot be warned in time, easily causing leakage risks; third, cleaning material residue inside the cylinder cover is difficult, requiring manual disassembly and cleaning, increasing operating costs.

[0004] Therefore, there is an urgent need for a kneader opening mechanism that is easy to operate, stable and reliable, has excellent sealing performance, and features adaptive adjustment, sealing status monitoring, and rapid cleaning functions, in order to solve the problems existing in the prior art.

[0041] Example

[0042] like Figures 1-6 As shown, this utility model discloses a lid-opening mechanism for a kneading machine, including a frame 100, a kneading cylinder 200, a cylinder cover 300, a drive module 400, a guide module 500, a sealing module 600, an adaptive adjustment module 700, an intelligent monitoring module 800, and a rapid cleaning module 900. The kneading cylinder 200 is fixedly mounted on the frame 100, and the cylinder cover 300 covers the top opening 201 of the kneading cylinder 200. The drive module 400 can drive the cylinder cover 300 to move up and down. Module 500 ensures the smoothness of cylinder head 300 movement, preventing deviation or jamming; sealing module 600 ensures the seal between cylinder head 300 and kneading cylinder 200, preventing material leakage; adaptive adjustment module 700 dynamically adjusts the lifting speed of cylinder head 300 according to the pressure inside kneading cylinder 200; intelligent monitoring module enables cylinder head 300 position monitoring, sealing status monitoring, and fault warning; rapid cleaning module 900 cleans residual material on cylinder head 300.

[0043] The cylinder head 300 is equipped with an observation window 302 on its top. The observation window 302 is made of double-layered tempered glass, which allows operators to easily observe the situation inside the kneading cylinder 200.

[0044] The drive module 400 includes cylinders 401, an air source processor, and control valves. Two cylinders 401 are fixedly mounted on the frame 100, located on opposite sides of the kneading cylinder body 200. The piston rods of cylinders 401 are fixedly connected to the cylinder head 300. The air source processor is connected to the air inlet of cylinders 401 via an air pipe, and the control valves are connected in series with the air pipe. When it is necessary to open the cover, the piston rod of cylinder 401 extends, simultaneously moving the cylinder head 300 away from the kneading cylinder body 200. When it is necessary to close the cylinder head 300 at the opening 201 of the kneading cylinder body 200, the piston rod of cylinder 401 retracts, simultaneously moving the cylinder head 300 away from the kneading cylinder body 200. The cylinder head 300 approaches the clamping cylinder 200 until the clamping cylinder 200 and the cylinder head 300 are closed together; the air source processor is connected to the air inlet and outlet of the cylinder 401 through an air pipe, which can regulate the working pressure; the control valve is an electromagnetic directional valve, connected in series on the air pipe, and the control valve is electrically connected to an external controller. The controller outputs an electrical signal to control the valve core of the electromagnetic directional valve to switch the intake and exhaust of the cylinder 401, thereby controlling the extension and retraction of the piston rod and driving the cylinder head 300 to rise and fall; the symmetrical arrangement of the two cylinders 401 can ensure that the cylinder head 300 is subjected to uniform force and avoid tilting caused by unilateral drive.

[0045] The cylinder 401 is equipped with a protective cover on its outer side. The protective cover is fixedly installed on the frame 100 and is made of transparent acrylic material. The protective cover can effectively protect the cylinder 401.

[0046] The guide module 500 includes guide posts 501 and guide sleeves 502. There are four guide posts 501, which are vertically fixed at the four corners of the top of the kneading cylinder 200. There are four guide sleeves 502, which are embedded in the cylinder head 300. The four guide sleeves 502 correspond to the four guide posts 501 respectively. The guide sleeves 502 are sleeved on the guide posts 501 and slide in cooperation with the guide posts 501. During the lifting and lowering of the cylinder head 300, the guide sleeves 502 slide smoothly along the guide posts 501. The guiding and positioning by the guide posts 501 and the guide sleeves 502 can ensure the stability of the cylinder head 300 during movement and prevent the cylinder head 300 from shifting or jamming.

[0047] Among them, the surface of the guide post 501 is chrome-plated, which can improve the wear resistance of the guide post 501; the inner wall of the guide sleeve 502 is coated with a polytetrafluoroethylene wear-resistant coating, which can reduce the sliding friction resistance between the guide post 501 and the guide sleeve 502.

[0048] The guide post 501 has a limit block 503 at its top, which is threaded to the guide post 501. The limit block 503 ensures that the guide post 501 and the guide sleeve 502 are always engaged, preventing the cylinder head 300 from exceeding the preset stroke when it moves up and down. The bottom of the limit block 503 has a silicone buffer pad, which can buffer the cylinder head 300 and prevent it from directly contacting the limit block 503 and causing a strong collision.

[0049] The sealing module 600 includes a sealing strip 601 and a groove 301. The groove 301 is formed at the bottom edge of the cylinder cover 300 and is an annular groove. The sealing strip 601 is disposed in the groove 301 and has a U-shaped cross-section. When the cylinder cover 300 and the kneading cylinder body 200 are closed, the bottom of the sealing strip 601 is tightly fitted with the edge of the top opening 201 of the kneading cylinder body 200, thereby ensuring the sealing between the kneading cylinder body 200 and the cylinder cover 300 and preventing material leakage.

[0050] Among them, the sealing strip 601 is made of oil-resistant nitrile rubber. The surface of the sealing strip 601 is coated with polytetrafluoroethylene, which not only improves wear resistance but also has anti-stick properties, reducing material residue.

[0051] The adaptive adjustment module 700 includes a flow control valve, an in-cylinder pressure sensor, and a speed controller. The flow control valve is connected in series on the air intake pipe of cylinder 401. The in-cylinder pressure sensor is fixedly installed on the inner wall of the kneading cylinder 200. The speed controller is electrically connected to both the flow control valve and the in-cylinder pressure sensor. When the pressure sensor in the kneading cylinder 200 detects that the pressure inside the kneading cylinder 200 is greater than a preset value, the speed controller controls the flow control valve and reduces the valve core opening, thereby reducing the compressed air intake and slowing down the extension speed of the piston rod of cylinder 401. This reduces the rising speed of the cylinder head 300, preventing high-pressure material from splashing out of the opening 201. When the pressure sensor detects that the pressure is less than the preset value, the speed controller controls the flow control valve to return to its maximum opening, and the cylinder head 300 rises and falls at a normal speed, balancing safety and operational efficiency.

[0052] The intelligent monitoring module 800 includes a displacement sensor, a sealing pressure sensor 801, and an early warning alarm 802. The displacement sensor is fixedly installed on the outer wall of the guide column 501, the sealing pressure sensor 801 is embedded in the inner side of the sealing strip 601, and the early warning alarm 802 is electrically connected to the sealing pressure sensor 801. Both the displacement sensor and the sealing pressure sensor 801 are electrically connected to an external controller. The displacement sensor can monitor the lifting position of the cylinder head 300 in real time. When the cylinder head 300 is detected to be close to its maximum stroke, the controller controls the solenoid reversing valve to decelerate and prevent overtravel. The sealing strip 601... Four sealing pressure sensors 801 are evenly arranged on the inner side. The sealing pressure sensors 801 can abut against the kneading cylinder 200. The sealing pressure sensors 801 are used to detect the contact pressure between the sealing strip 601 and the kneading cylinder 200. The early warning alarm 802 includes an audible and visual alarm and a buzzer. When the sealing pressure sensor 801 detects that the pressure on the sealing surface is lower than the preset threshold, the early warning alarm 802 is activated to remind the operator to replace the sealing strip 601 in time. The data from the displacement sensor and the sealing pressure sensor 801 are transmitted to the controller in real time, which facilitates equipment maintenance and fault tracing.

[0053] The rapid cleaning module 900 includes high-pressure air nozzles 901 and spray heads 902. There are four high-pressure air nozzles 901, which are evenly distributed on the inner edge of the cylinder cover 300. The high-pressure air nozzles 901 are connected to an external high-pressure air source through air pipes. The spray heads 902 are located in the middle of the inner side of the cylinder cover 300, and the water outlet of the spray heads 902 is located on the side wall of the spray heads 902. The spray heads 902 are connected to an external cleaning liquid supply system through water pipes. Both the high-pressure air nozzles 901 and the spray heads 902 are connected to an external controller. The high-pressure air nozzles 901 can blow away the residual material on the inner side of the cylinder cover 300. After blowing, the spray heads 902 can rotate 360° and wash the inner side of the cylinder cover 300 with water.

[0054] The working process of this utility model is as follows: When the cylinder head 300 needs to be opened, the controller controls the electromagnetic reversing valve to operate. Compressed air enters the rodless chamber of the cylinder 401 after being filtered by the air source processor, pushing the piston rod to extend and causing the cylinder head 300 to rise. At this time, the cylinder pressure sensor in the adaptive adjustment module 700 detects the pressure inside the kneading cylinder 200 in real time. If the pressure is too high, the speed controller immediately controls the flow regulating valve to reduce the intake air volume, and the cylinder head 300 rises slowly to avoid material splashing. At the same time, the displacement sensor monitors the position of the cylinder head 300 in real time. When it approaches the limit block 503, it automatically reduces the rising speed and finally stops smoothly.

[0055] After opening the cover, if it is necessary to clean the inside of the cylinder cover 300, start the rapid cleaning module 900; first, blow away the residual material through the high-pressure air nozzle 901. After blowing, the spray head 902 sprays out cleaning fluid to rinse away stubborn residue; after cleaning, turn off the cleaning system and start the cylinder 401 again to drive the cylinder cover 300 down until the sealing strip 601 is in contact with the top of the kneading cylinder 200; at this time, the sealing pressure sensor 801 inside the sealing strip 601 detects the sealing surface pressure. If the pressure is up to standard, the equipment can operate normally; if the pressure is insufficient, the early warning alarm 802 is activated to remind you to replace the sealing strip 601.

[0056] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
