Description

Technical Field

[0001] This utility model relates to the field of sealant production technology, specifically to a temperature-controlled kneading and mixing machine for sealant production. Background Technology

[0002] In the field of sealant production, kneading and stirring are the core processes for material mixing and reaction, while temperature control directly affects the uniformity of the sealant's composition and the stability of its performance. Related integrated equipment is widely used in existing technologies. Existing sealant production equipment typically integrates a kneading system and a stirring system. The kneading system often employs a twin-screw or paddle-type structure, achieving preliminary mixing and plasticization of the material through shearing and extrusion. The stirring system is equipped with different types of agitators to ensure continuous flow of the material during the reaction process, avoiding localized stagnation.

[0003] In existing technologies, single-shaft stirring has a limited stirring coverage area, easily leading to dead zones in raw material mixing. This results in insufficient dispersion of thickener and filler agglomeration in some areas, causing problems such as abnormal viscosity and uneven density in the finished sealant, significantly reducing the product qualification rate. Furthermore, the lack of temperature control means that the raw material temperature cannot be accurately controlled. If the temperature is too low, the chemical reaction between raw materials slows down or even stops, affecting the viscosity and stability of the sealant. If the temperature is too high, the raw materials are prone to scorching. In addition, existing technologies lack a reciprocating oscillating component, relying solely on rotational stirring, which cannot cover all areas within the kneading drum. Dead zones will exist for a long time at the drum wall edges and bottom corners. The lack of oscillation function also results in low stirring efficiency, requiring extended stirring time to achieve a basic mixing effect, indirectly prolonging the production cycle and affecting equipment capacity. Finally, the lack of a stable spiral feeding structure in existing technologies leads to uneven feeding, causing unstable feed rates to subsequent equipment, affecting processing quality, and even causing equipment malfunctions due to excessive or insufficient feeding, further reducing overall production efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a temperature-controlled kneading and mixing integrated machine for sealant production. It solves the problems of limited mixing coverage, easy formation of raw material mixing dead zones, and inaccurate control of raw material temperature when lacking temperature control function in the prior art; the inability to cover all areas inside the kneading cylinder by relying solely on rotary mixing, resulting in long-term mixing dead zones at the cylinder wall edges, bottom corners, etc.; the lack of oscillation function, resulting in low mixing efficiency of the equipment; and the lack of a stable spiral feeding structure, which leads to uneven feeding, resulting in unstable feed rate of subsequent equipment and affecting processing quality.

[0005] According to one aspect, at least one embodiment of the present invention provides a temperature-controlled kneading and mixing machine for producing sealant grease, comprising: The frame has an L-shaped fixing plate fixedly connected to its left side, and a controller fixedly connected to the left side wall of the L-shaped fixing plate. Rotating shafts are rotatably connected to the inner walls of both sides of the frame. A kneading cylinder is fixedly connected to one end of the two rotating shafts that are close to each other. A sealing cover is hinged to the top of the kneading cylinder through a hinge, and a handle is fixedly connected to the top of the sealing cover. A temperature-controlled biaxial stirring assembly is provided on both the inner and outer sides of the kneading cylinder. The temperature-controlled biaxial stirring assembly is used for biaxial stirring and temperature control of the sealing grease. A reciprocating oscillating assembly is disposed on the right side of the frame and is used to reciprocate the kneading cylinder. A spiral feeding assembly is disposed at the bottom of the kneading cylinder and is used to feed the processed raw materials.

[0006] For example, in at least one embodiment of the present invention, the temperature-controlled kneading and mixing machine for producing sealant grease includes a temperature-controlled dual-shaft mixing assembly, which includes a motor. The motor is fixedly connected to the rear side of the outer wall of the kneading cylinder. A toothed pulley is fixedly connected to the bottom output shaft of the motor, and a gearbox is fixedly connected to the bottom of the kneading cylinder.

[0007] For example, in at least one embodiment of the present invention, a temperature-controlled kneading and mixing machine for producing sealant grease is provided, wherein two symmetrical rotating rods are rotatably connected to the inner top wall of the gearbox, and gears are fixedly connected to the outer walls of both rotating rods. The two gears mesh with each other. The bottom of the rear rotating rod extends through to the bottom of the gearbox and is fixedly connected to a toothed pulley. The outer walls of the toothed pulleys are fitted with synchronous toothed belts that mesh with them. The tops of both rotating rods extend through to the interior of the kneading cylinder and are fixedly connected to a stirring rod. The outer walls of both stirring rods are fixedly connected to a plurality of stirring blades that are equidistant from top to bottom and arranged in a circular array. The stirring blades on the outer walls of the two stirring rods are staggered vertically.

[0008] For example, in at least one embodiment of the present invention, a temperature-controlled kneading and mixing machine for producing sealant grease is provided, wherein the shell of the kneading cylinder is provided with a heating chamber, a heating plate is fixedly connected to the inner wall of the heating chamber, a temperature sensor is fixedly connected to the inner wall of the kneading cylinder, and the controller is electrically connected to the motor, the heating plate, and the temperature sensor respectively.

[0009] For example, in at least one embodiment of the present invention, the temperature-controlled kneading and mixing machine for producing sealing grease includes a fixed frame, which is fixedly connected to the right side wall of the frame. A servo motor is fixedly connected to the bottom of the fixed frame. The output shaft of the servo motor passes through the interior of the fixed frame and is fixedly connected to a rotating disk. A circular groove is opened inside the rotating disk away from its center. A slide rod is slidably connected inside the circular groove. A limit block is fixedly connected to the bottom of the slide rod, and a sliding sleeve is fixedly connected to the top of the slide rod.

[0010] For example, in at least one embodiment of the present invention, a temperature-controlled kneading and mixing machine for producing sealing grease is provided, in which a rotating column is rotatably connected to the upper part of the inner walls on the left and right sides of the fixed frame, two connecting plates are fixedly connected to the outer wall of the rotating column, and a sliding rod II is fixedly connected to the lower part of the opposite surfaces of the two connecting plates, and the outer wall of the sliding rod II is slidably connected to the sliding sleeve.

[0011] For example, in at least one embodiment of the present invention, the temperature-controlled kneading and mixing machine for producing sealing grease has the left end of the rotating column extending through the left side wall of the fixed frame and being fixedly connected to the rotating shaft, and the controller is electrically connected to the servo motor.

[0012] For example, in at least one embodiment of the present invention, the temperature-controlled kneading and mixing machine for producing sealant grease includes a feeding cylinder, a spiral blade rotatably connected inside the feeding cylinder, a stepper motor fixedly connected to the rear side wall of the feeding cylinder, the output shaft of the stepper motor passing through the inside of the feeding cylinder and fixedly connected to the spiral blade, a feeding pipe communicating with the inside of the kneading cylinder fixedly connected to the bottom of the kneading cylinder, the bottom of the feeding pipe fixedly connected to the feeding cylinder, a solenoid valve fixedly connected to the outer wall of the feeding pipe, a fixed seat fixedly connected to the bottom of the kneading cylinder fixedly connected to the middle of the outer wall of the feeding cylinder, and the controller electrically connected to the stepper motor and the solenoid valve respectively.

[0013] The beneficial effects of the embodiments of this utility model are as follows: In this invention, the temperature-controlled dual-shaft stirring assembly enables all-around stirring of the sealing grease material within the kneading drum. Compared to single-shaft stirring, dual-shaft reverse stirring generates a more complex material flow trajectory, effectively breaking up material agglomeration and preventing localized material accumulation. Simultaneously, a temperature sensor monitors the material temperature in real time, feeding the data back to the controller, which automatically adjusts the heating power of the heating plate to stabilize the material temperature within the set range, preventing material deterioration or performance degradation due to improper temperature. The reciprocating oscillating assembly drives the kneading drum to oscillate back and forth around its rotation axis, causing the material inside the drum to tumble up and down and left and right. Combined with the rotational force of the dual-shaft stirring, this creates a "rotational stirring + reciprocating stirring" effect. The combined "tumbling" motion continuously pushes raw materials from dead corners towards the mixing area, ensuring that all raw materials in the kneading cylinder are fully mixed, significantly improving the uniformity of raw material mixing and preventing the performance of the sealant from being affected by insufficient mixing in certain areas. At the same time, the combination of the two motions can effectively shorten the mixing time for a single sealant production, increase the output per unit time of the equipment, and improve the overall production efficiency. The spiral feeding component can smoothly convey the sealant forward along the inner wall of the feeding cylinder. With the control of the feeding timing by the solenoid valve, the feeding speed and feeding amount can be precisely adjusted to avoid packaging overflow due to excessive feeding or packaging gaps due to insufficient feeding. This ensures the continuous and stable operation of subsequent processes such as packaging and dispensing, and improves the smoothness of the overall production process. Attached Figure Description

[0023] like Figures 1-4 As shown, it illustrates a temperature-controlled kneading and mixing machine for producing sealant grease according to one embodiment of the present invention, comprising: The frame 1 has an L-shaped fixing plate 10 fixedly connected to the left side of the frame 1. The left side wall of the L-shaped fixing plate 10 is fixedly connected to the controller 11. The inner walls of both the left and right sides of the frame 1 are rotatably connected to rotating shafts 15. The two rotating shafts 15 are fixedly connected to a kneading cylinder 12 at their close ends. The top of the kneading cylinder 12 is hinged to a sealing cover 13. The top of the sealing cover 13 is fixedly connected to a handle 14. Temperature-controlled dual-shaft stirring assembly 2 is installed on both the inner and outer sides of the kneading cylinder 12. The temperature-controlled dual-shaft stirring assembly 2 is used for dual-shaft stirring and temperature control of the sealing grease. The reciprocating oscillating assembly 3 is located on the right side of the frame 1 and is used to reciprocate the kneading cylinder 12. The spiral feeding assembly 4 is located at the bottom of the kneading cylinder 12 and is used to feed the processed raw materials.

[0024] In some examples, the core support structure is a frame 1, which is welded from carbon steel and has high strength support performance. The controller 11 is a PLCS7-1200 programmable logic controller with an integrated touch screen and physical operation buttons for automated control and parameter adjustment of various components of the device. The inner walls of the left and right sides of the frame 1 are rotatably connected to rotating shafts 15 via deep groove ball bearings. The two rotating shafts 15 are fixedly connected to a kneading cylinder 12 at their closest ends via a coupling. The kneading cylinder 12 is a cylindrical body made of stainless steel and is used to hold and knead the sealing grease material. The sealing cover 13 has a silicone rubber sealing ring attached to the contact edge with the kneading cylinder 12 to ensure sealing performance. At the same time, the sealing cover 13 is snapped into the kneading cylinder 12 by a set buckle. A handle 14 is fixedly connected to the top center of the sealing cover 13 by welding. The handle 14 is made of aluminum alloy with an anodized surface for easy opening and closing of the sealing cover 13 by the operator.

[0025] Temperature-controlled dual-shaft stirring assembly 2 includes a motor 20, which is fixedly connected to the rear side of the outer wall of the kneading cylinder 12. The bottom output shaft of the motor 20 is fixedly connected to a toothed pulley 21, and the bottom of the kneading cylinder 12 is fixedly connected to a gearbox 24.

[0026] The inner top wall of the gearbox 24 is rotatably connected to two symmetrical rotating rods 25. Gears 26 are fixedly connected to the outer walls of both rotating rods 25. The two gears 26 mesh with each other. The bottom of the rear rotating rod 25 extends through to the bottom of the gearbox 24 and is fixedly connected to a toothed pulley 22. The outer walls of the toothed pulleys 21 and 22 are fitted with synchronous toothed belts 23 that mesh with them. The tops of both rotating rods 25 extend through to the inside of the kneading cylinder 12 and are fixedly connected to stirring rods 27. Several stirring blades 28 are fixedly connected to the outer walls of both stirring rods 27, which are equidistant from top to bottom and arranged in a circular array. The stirring blades 28 on the outer walls of the two stirring rods 27 are staggered vertically.

[0027] The shell of the kneading cylinder 12 is provided with a heating chamber, and a heating plate 29 is fixedly connected to the inner wall of the heating chamber. A temperature sensor 210 is fixedly connected to the inner wall of the kneading cylinder 12. The controller 11 is electrically connected to the motor 20, the heating plate 29, and the temperature sensor 210 respectively.

[0028] In some examples, the bottom output shaft of motor 20 is fixedly connected to toothed pulley 21 via a flat key. A gearbox 24, filled with gear lubricating oil, is fixedly connected to the bottom outer wall of kneading cylinder 12 via a bracket. Two symmetrically arranged rotating rods 25 are rotatably connected to the inner top wall of gearbox 24 via bearings. Gears 26 are fixedly connected to the outer walls of both rotating rods 25 via flat keys. The two gears 26 mesh with each other to ensure that the two rotating rods 25 rotate synchronously in opposite directions. The bottom of the rear rotating rod 25 extends through the bottom of gearbox 24 and is fixedly connected to toothed pulley 22 via a flat key. The synchronous toothed belt 23, made of polyurethane, is used to transmit power from motor 20. The tops of both rotating rods 25 extend through the interior of kneading cylinder 12 and are fixedly connected to stirring rods 27 via couplings. Several stirring rods 27, evenly spaced vertically and arranged in a circular array, are fixedly connected to the outer walls of both stirring rods 27 via welding. The mixing blades 28 on the outer walls of the front and rear mixing rods 27 are staggered to avoid dead corners and motion interference during mixing, ensuring thorough mixing of raw materials. The kneading cylinder 12 has an annular heating chamber inside its shell. The heating plate 29 is a stainless steel electric heating plate of model SRY2-220 / 1, with four plates evenly distributed along the inner wall of the heating chamber, which can achieve uniform heating of the entire kneading cylinder 12. The temperature sensor 210 is a platinum resistance temperature sensor of model PT100, used to monitor the temperature of the raw materials inside the kneading cylinder 12 in real time. The signal input terminal of the controller 11 is connected to the temperature sensor 210 through a wire, and the signal output terminal is connected to the motor 20 and the heating plate 29 through wires respectively. Based on the temperature data fed back by the temperature sensor 210, the controller can automatically adjust the heating power of the heating plate 29 to stabilize the raw material temperature within the set range, and at the same time control the start, stop and speed of the motor 20 to adapt to the mixing requirements at different temperatures.

[0029] During operation, the operator opens the sealing cover 13 on top of the kneading cylinder 12 through the handle 14 on the top of the sealing cover 13, and pours the basic raw materials required for the production of sealing grease (such as mineral oil, thickener, filler, etc.) into the kneading cylinder 12 according to the formula ratio. After the raw materials are added, the sealing cover 13 is closed. The sealing ring at the contact edge between the sealing cover 13 and the kneading cylinder 12 ensures that the cylinder is sealed and is fixed by the fastener. Then, the production parameters, including stirring speed, heating temperature, stirring time, swing angle, etc., are input through the controller 11 to complete the pre-production preparation. After the parameters are set, the controller 11 sends a start signal to the motor 20 in the temperature-controlled dual-shaft stirring assembly 2. After the motor 20 starts, its bottom output shaft drives the toothed pulley 21 to rotate. Through the transmission action of the synchronous toothed belt 23, the toothed pulley 21 drives the toothed pulley 22 at the bottom of the gearbox 24 to rotate synchronously, which in turn drives the rear rotating rod 25, which is fixed to the toothed pulley 22, to rotate. Since the gear 26 on the outer wall of the rear rotating rod 25 meshes with the gear 26 on the outer wall of the front rotating rod 25, the rotation of the rear rotating rod 25 will drive the front rotating rod 25 to rotate. 5. The two rotating rods 25 drive the stirring rods 27, which extend from the top into the kneading cylinder 12, to rotate in opposite directions. The stirring blades 28 on the outer wall of the stirring rods 27 are staggered and rotate with the stirring rods 27, performing biaxial reverse stirring of the sealing grease material in the kneading cylinder 12, breaking up the agglomeration of the material and achieving preliminary mixing. During the stirring process, the temperature sensor 210 on the inner wall of the kneading cylinder 12 monitors the material temperature in real time and converts the temperature data into an electrical signal, which is then transmitted to the controller 11. If the material temperature is lower than the set value, the controller 11 controls the kneading cylinder 12 to heat up. The heating plate 29 inside the cavity is energized and heated, transferring heat to the raw material through the shell of the kneading cylinder 12, causing the raw material temperature to gradually rise. When the temperature sensor 210 detects that the raw material temperature has reached the set value, the controller 11 automatically adjusts the heating power of the heating plate 29 to maintain the temperature stable within the set range, avoiding excessively high temperatures that could lead to raw material deterioration or excessively low temperatures that could affect the mixing effect. At the same time, the controller 11 can dynamically adjust the speed of the motor 20 according to temperature changes, appropriately reducing the speed at low temperatures to reduce raw material sticking to the wall, and increasing the speed at high temperatures to enhance the uniformity of mixing. In this embodiment, the temperature-controlled dual-shaft stirring assembly 2 utilizes two stirring rods rotating synchronously in opposite directions, combined with staggered stirring blades, to form an all-round stirring of the sealing grease raw material in the kneading cylinder. Compared with single-shaft stirring, dual-shaft reverse stirring can generate a more complex material flow trajectory, effectively breaking the raw material agglomeration and avoiding local raw material accumulation. At the same time, the temperature sensor monitors the raw material temperature in real time, and after feeding the data back to the controller, the controller automatically adjusts the heating power of the heating plate to stabilize the raw material temperature within the set range, avoiding raw material deterioration or performance degradation caused by improper temperature.

[0030] like Figure 5 As shown, in another embodiment of the present invention, the reciprocating swing assembly 3 includes a fixed frame 30, which is fixedly connected to the right side wall of the frame 1. A servo motor 31 is fixedly connected to the bottom of the fixed frame 30. The output shaft of the servo motor 31 passes through the interior of the fixed frame 30 and is fixedly connected to a rotating disk 32. A circular slot 33 is opened inside the rotating disk 32 away from its center. A slide rod 34 is slidably connected inside the circular slot 33. A limit block is fixedly connected to the bottom of the slide rod 34, and a sliding sleeve 38 is fixedly connected to the top of the slide rod 34.

[0031] Rotating columns 35 are rotatably connected to the upper part of the inner walls on both sides of the fixed frame 30. Two connecting plates 36 are fixedly connected to the outer wall of the rotating columns 35. Slide rods 37 are fixedly connected to the lower part of the opposite surfaces of the two connecting plates 36. The outer wall of slide rods 37 is slidably connected to the sliding sleeve 38.

[0032] The left end of the rotating column 35 extends through to the left side wall of the fixed frame 30 and is fixedly connected to the rotating shaft 15. The controller 11 is electrically connected to the servo motor 31.

[0033] In some examples, a servo motor 31 is fixedly connected to the bottom center of the fixed frame 30 via a motor bracket and bolts. The servo motor 31 is an AC servo motor of model 130ST-M06025, which has high-precision position control performance. The output shaft of the servo motor 31 passes through the interior of the fixed frame 30 and is fixedly connected to a rotating disk 32 via a coupling. The rotating disk 32 has a circular slot 33 located away from its center. A slide rod 34 is slidably connected inside the circular slot 33. A limit block is fixedly connected to the bottom of the slide rod 34 by welding to prevent the slide rod 34 from dislodging from the circular slot 33. A sliding sleeve 38 is fixedly connected to the top by welding. The sliding sleeve 38 is made of brass and its inner wall is polished to reduce friction. Rotating columns 35 are rotatably connected to the upper part of the inner walls on both sides of the fixed frame 30 via deep groove ball bearings. Two symmetrical connecting plates 36 are fixedly connected to the outer wall of the rotating column 35 by welding. Slide rod 2 37 is fixedly connected to the lower part of the opposite face of the two connecting plates 36 by welding. The left end of the rotating column 35 extends through the left side wall of the fixed frame 30 and is fixedly connected to the rotating shaft 15 on the right side of the frame 1 via a coupling. The controller 11 is electrically connected to the servo motor 31 via a servo driver and can control the speed and rotation angle of the servo motor 31. Then, through the transmission of the rotating disk 32, slide rod 1 34, sliding sleeve 38 and slide rod 2 37, the rotating column 35 and the rotating shaft 15 are driven to reciprocate, and finally the kneading cylinder 12 is reciprocated.

[0034] To further improve the kneading effect of raw materials and reduce dead zones in the mixing process, the controller 11 synchronously starts the servo motor 31 in the reciprocating oscillating assembly 3 during the mixing process. The output shaft of the servo motor 31 drives the rotating disk 32 inside the fixed frame 30 to rotate at a constant speed. The circular slot 33 on the rotating disk 32 rotates with the rotating disk 32, causing the sliding rod 34 inside to rotate while making up-down reciprocating motion (the bottom limit block prevents the sliding rod 34 from falling out). The sliding sleeve 38 at the top of the sliding rod 34 moves with the sliding rod 34 and slides left and right along the sliding rod 37 between the connecting plates 36. Through the cooperation of the sliding sleeve 38 and the sliding rod 37, the linear reciprocating motion of the sliding rod 34 is converted into the reciprocating rotation of the rotating column 35. The left end of the rotating column 35 is fixedly connected to the rotating shaft 15 on the right side of the frame 1, thereby driving the rotating shaft 15 and the kneading cylinder 12 to rotate around the axis of the rotating shaft 15. The reciprocating oscillation of the kneading cylinder 12 causes the internal materials to tumble up and down. Combined with the dual-shaft stirring, this forms a compound kneading action of "stirring + oscillation," ensuring that the materials are mixed thoroughly within the kneading cylinder 12 without any dead corners. This improves the uniformity and fineness of the sealant. In this embodiment, the reciprocating oscillation component 3 drives the kneading cylinder to oscillate back and forth around the rotation axis, causing the materials inside the cylinder to tumble up and down and left and right. Combined with the rotational force of the dual-shaft stirring, this forms a compound motion of "rotational stirring + reciprocating tumbling," continuously pushing the materials in dead corners towards the stirring area. This ensures that all materials in the kneading cylinder are fully stirred, significantly improving the uniformity of material mixing and preventing the sealant's performance from being affected by insufficient mixing in certain areas. At the same time, the combination of these two motions effectively shortens the stirring time for a single sealant production, increases the equipment's output per unit time, and improves overall production efficiency. like Figure 6 As shown, a spiral feeding assembly 4 is illustrated in another embodiment of the present invention. The spiral feeding assembly 4 includes a feeding cylinder 40, a spiral blade 41 rotatably connected inside the feeding cylinder 40, a stepper motor 42 fixedly connected to the rear side wall of the feeding cylinder 40, the output shaft of the stepper motor 42 passing through the interior of the feeding cylinder 40 and fixedly connected to the spiral blade 41, a feeding pipe 44 communicating with the interior of the kneading cylinder 12 fixedly connected to the bottom, the bottom of the feeding pipe 44 fixedly connected to the feeding cylinder 40, a solenoid valve 45 fixedly connected to the outer wall of the feeding pipe 44, a fixing seat 43 fixedly connected to the bottom of the kneading cylinder 12 fixedly connected to the middle of the outer wall of the feeding cylinder 40, and a controller 11 electrically connected to the stepper motor 42 and the solenoid valve 45 respectively.

[0035] In some examples, the feeding cylinder 40 is a cylindrical body made of stainless steel. Inside, a helical blade 41, also made of stainless steel, is rotatably connected via a deep groove ball bearing. This helical blade 41 is welded to a rotating shaft and used to transport the sealing grease material. The stepper motor 42 is a two-phase stepper motor, model 86HS80. Its output shaft extends into the interior of the feeding cylinder 40 and is fixedly connected to the rotating shaft of the helical blade 41 via a coupling, enabling precise speed control of the helical blade 41. A discharge pipe 44, made of stainless steel, is welded to the center of the bottom of the kneading cylinder 12, communicating with its interior. The bottom is fixedly connected to the top of the conveying cylinder 40 via a flange to ensure that the raw material falls smoothly into the conveying cylinder 40. The outer wall of the discharge pipe 44 is fixedly connected to a solenoid valve 45 via a flange. The solenoid valve 45 is a stainless steel solenoid valve of model ZCS-15, which is used to control the opening and closing of the discharge pipe 44 and realize the control of the discharge timing. The fixing seat 43 is used to support and fix the conveying cylinder 40. The signal output terminal of the controller 11 is connected to the stepper motor 42 and the solenoid valve 45 via wires respectively. According to the production needs, the opening of the solenoid valve 45 and the speed of the stepper motor 42 can be controlled to realize the quantitative and stable discharge of the sealing grease raw material.

[0036] After the sealant raw material has been kneaded and mixed in the kneading cylinder 12 for the set mixing time, the controller 11 first shuts off the motor 20 and the servo motor 31 to stop the mixing and oscillation. Then, it controls the solenoid valve 45 on the outer wall of the feeding pipe 44 to open, and the finished sealant in the kneading cylinder 12 falls into the conveying cylinder 40 of the spiral feeding assembly 4 through the feeding pipe 44. At the same time, the controller 11 starts the stepper motor 42 on the rear side wall of the conveying cylinder 40. The output shaft of the stepper motor 42 drives the spiral blades 41 inside the conveying cylinder 40 to rotate precisely. During the rotation of the spiral blades 41, the sealant in the conveying cylinder 40 is pushed forward along the cylinder axis and discharged from the discharge end of the conveying cylinder 40, realizing the finished product feeding. The controller 11 can precisely adjust the feeding speed and amount by controlling the rotation angle and speed of the stepper motor 42 to meet the quantitative requirements of subsequent packaging or processing steps. After feeding is completed, the controller 11 closes the solenoid valve 45 and the stepper motor 42 to complete the complete process of sealant production. In this embodiment, the spiral feeding component 4 can smoothly convey the sealant forward along the inner wall of the feeding cylinder. With the control of the feeding timing by the solenoid valve, the feeding speed and amount can be precisely adjusted to avoid packaging overflow due to excessive feeding or packaging gap due to insufficient feeding. This ensures the continuous and stable operation of subsequent processes such as packaging and dispensing, and improves the smoothness of the overall production process.

[0037] The working principle and usage process of this utility model are as follows: During operation, the operator opens the sealing cover 13 at the top of the kneading cylinder 12 through the handle 14 at the top of the sealing cover 13, and pours the basic raw materials (such as mineral oil, thickener, filler, etc.) required for the production of sealing grease into the kneading cylinder 12 according to the formula ratio. After the raw materials are added, the sealing cover 13 is closed. The sealing ring at the contact edge between the sealing cover 13 and the kneading cylinder 12 ensures that the cylinder is sealed, and it is fixed by the fastener. Then, the production parameters, including stirring speed, heating temperature, stirring time, swing angle, etc., are input through the controller 11 to complete the pre-production preparation. After the parameters are set, the controller 11 sends a start signal to the motor 20 in the temperature-controlled dual-shaft stirring assembly 2. After the motor 20 starts, its bottom output shaft drives the toothed pulley 21 to rotate. Through the transmission action of the synchronous toothed belt 23, the toothed pulley 21 drives the toothed pulley 22 at the bottom of the gearbox 24 to rotate synchronously, which in turn drives the rear rotating rod 25, which is fixed to the toothed pulley 22, to rotate. Since the gear 26 on the outer wall of the rear rotating rod 25 meshes with the gear 26 on the outer wall of the front rotating rod 25, the rotation of the rear rotating rod 25 will drive the front rotating rod 25 to rotate. 5. The two rotating rods 25 drive the stirring rods 27, which extend from the top into the kneading cylinder 12, to rotate in opposite directions. The stirring blades 28 on the outer wall of the stirring rods 27 are staggered and rotate with the stirring rods 27, performing biaxial reverse stirring of the sealing grease material in the kneading cylinder 12, breaking up the agglomeration of the material and achieving preliminary mixing. During the stirring process, the temperature sensor 210 on the inner wall of the kneading cylinder 12 monitors the material temperature in real time and converts the temperature data into an electrical signal, which is then transmitted to the controller 11. If the material temperature is lower than the set value, the controller 11 controls the kneading cylinder 12 to heat up. The heating plate 29 inside the cavity is energized and heated, transferring heat to the raw material through the shell of the kneading cylinder 12, causing the raw material temperature to gradually rise. When the temperature sensor 210 detects that the raw material temperature has reached the set value, the controller 11 automatically adjusts the heating power of the heating plate 29 to maintain the temperature stable within the set range, avoiding excessively high temperatures that could lead to raw material deterioration or excessively low temperatures that could affect the mixing effect. At the same time, the controller 11 can dynamically adjust the speed of the motor 20 according to temperature changes, appropriately reducing the speed at low temperatures to reduce raw material sticking to the wall, and increasing the speed at high temperatures to enhance the uniformity of mixing. In this embodiment, the temperature-controlled dual-shaft stirring assembly 2 utilizes two stirring rods rotating synchronously in opposite directions, combined with staggered stirring blades, to form an all-round stirring of the sealing grease raw material in the kneading cylinder. Compared with single-shaft stirring, dual-shaft reverse stirring can generate a more complex material flow trajectory, effectively breaking the raw material agglomeration and avoiding local raw material accumulation. At the same time, the temperature sensor monitors the raw material temperature in real time, and after feeding the data back to the controller, the controller automatically adjusts the heating power of the heating plate to stabilize the raw material temperature within the set range, avoiding raw material deterioration or performance degradation caused by improper temperature.

[0038] To further improve the kneading effect of raw materials and reduce dead zones in the mixing process, the controller 11 synchronously starts the servo motor 31 in the reciprocating oscillating assembly 3 during the mixing process. The output shaft of the servo motor 31 drives the rotating disk 32 inside the fixed frame 30 to rotate at a constant speed. The circular slot 33 on the rotating disk 32 rotates with the rotating disk 32, causing the sliding rod 34 inside to rotate while making up-down reciprocating motion (the bottom limit block prevents the sliding rod 34 from falling out). The sliding sleeve 38 at the top of the sliding rod 34 moves with the sliding rod 34 and slides left and right along the sliding rod 37 between the connecting plates 36. Through the cooperation of the sliding sleeve 38 and the sliding rod 37, the linear reciprocating motion of the sliding rod 34 is converted into the reciprocating rotation of the rotating column 35. The left end of the rotating column 35 is fixedly connected to the rotating shaft 15 on the right side of the frame 1, thereby driving the rotating shaft 15 and the kneading cylinder 12 to rotate around the axis of the rotating shaft 15. The reciprocating oscillation of the kneading cylinder 12 causes the internal materials to tumble up and down. Combined with the dual-shaft stirring, this forms a compound kneading action of "stirring + oscillation," ensuring that the materials are mixed thoroughly within the kneading cylinder 12 without any dead corners. This improves the uniformity and fineness of the sealant. In this embodiment, the reciprocating oscillation component 3 drives the kneading cylinder to oscillate back and forth around the rotation axis, causing the materials inside the cylinder to tumble up and down and left and right. Combined with the rotational force of the dual-shaft stirring, this forms a compound motion of "rotational stirring + reciprocating tumbling," continuously pushing the materials in dead corners towards the stirring area. This ensures that all materials in the kneading cylinder are fully stirred, significantly improving the uniformity of material mixing and preventing the sealant's performance from being affected by insufficient mixing in certain areas. At the same time, the combination of these two motions effectively shortens the stirring time for a single sealant production, increases the equipment's output per unit time, and improves overall production efficiency.

[0039] After the sealant raw material has been kneaded and mixed in the kneading cylinder 12 for the set mixing time, the controller 11 first shuts off the motor 20 and the servo motor 31 to stop the mixing and oscillation. Then, it controls the solenoid valve 45 on the outer wall of the feeding pipe 44 to open, and the finished sealant in the kneading cylinder 12 falls into the conveying cylinder 40 of the spiral feeding assembly 4 through the feeding pipe 44. At the same time, the controller 11 starts the stepper motor 42 on the rear side wall of the conveying cylinder 40. The output shaft of the stepper motor 42 drives the spiral blades 41 inside the conveying cylinder 40 to rotate precisely. During the rotation of the spiral blades 41, the sealant in the conveying cylinder 40 is pushed forward along the cylinder axis and discharged from the discharge end of the conveying cylinder 40, realizing the finished product feeding. The controller 11 can precisely adjust the feeding speed and amount by controlling the rotation angle and speed of the stepper motor 42 to meet the quantitative requirements of subsequent packaging or processing steps. After feeding is completed, the controller 11 closes the solenoid valve 45 and the stepper motor 42 to complete the complete process of sealant production. In this embodiment, the spiral feeding component 4 can smoothly convey the sealant forward along the inner wall of the feeding cylinder. With the control of the feeding timing by the solenoid valve, the feeding speed and amount can be precisely adjusted to avoid packaging overflow due to excessive feeding or packaging gap due to insufficient feeding. This ensures the continuous and stable operation of subsequent processes such as packaging and dispensing, and improves the smoothness of the overall production process.
