Description
Technical Field
[0001] This utility model relates to the field of adhesive production equipment technology, specifically a pull-out adhesive mixer for mixing high-viscosity adhesives. Background Technology
[0002] Adhesive mixers are key equipment in the production of adhesives, sealants, and other similar products. While horizontal mixers are widely used due to their simple structure, they still have the following drawbacks:
[0003] 1. Difficulty in cleaning the stirring components: Traditional stirring shafts and blades are fixedly installed inside the cylinder. During cleaning, they can only be rinsed inside through the feed inlet, which easily creates cleaning dead corners at the bottom of the cylinder and on the back of the blades. Especially for high-viscosity adhesive residues, the limited space for manual brushing leads to incomplete cleaning and cross-contamination.
[0004] 2. Unloading residue and sealing defects: Equipment that uses screw push or ordinary valve for unloading leaves a large amount of residue at the bottom of the cylinder after unloading; ordinary valves are prone to leakage due to adhesive adhesion when closed, requiring frequent replacement of seals and affecting the stability of continuous production.
[0005] 3. Insufficient stirring adaptability: Fixed blades cannot dynamically adjust the stirring range according to the viscosity of the adhesive; high-viscosity adhesives are prone to forming a laminar flow zone at the far end of the blades, while excessive stirring of low-viscosity adhesives leads to energy waste and large fluctuations in mixing uniformity. Utility Model Content
[0006] To overcome the problems of numerous cleaning dead corners, high unloading residue rate, and poor stirring adaptability of traditional equipment in the prior art, this utility model provides a pull-out adhesive mixer. Through the pull-out stirring component combined with the flip-plate unloading structure and dynamic adjustment of the paddle position, it can achieve precise control of cleaning without dead corners, low unloading residue rate, and high mixing uniformity.
[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: a pull-out adhesive mixer, including a frame, which forms the basic support of the equipment; a cylinder, arranged at one end of the upper part of the frame and used to contain the adhesive, with a detachable cover plate with a feed inlet on its top; a stirring assembly, including a mixing component and a driving component; the mixing component is arranged on the side of the cylinder and can be pulled out horizontally, including: a base, which is arranged inside the frame and can reciprocate along its length; a first motor, which is installed on the upper part of the base; a shaft, which is transversely placed inside the cylinder and driven to rotate by the first motor; paddles, which are spaced apart on the upper part of the shaft and used to stir the adhesive; the driving component is arranged in the pulling direction of the mixing component on the upper part of the frame and is used to drive the base to move, so that the mixing component abuts or separates from the cylinder; and a discharge assembly, which is arranged at the bottom of the cylinder and adopts a flip-plate structure for realizing the discharge operation of the adhesive inside the cylinder.
[0008] The aforementioned pull-out adhesive mixer includes a drive component comprising guide rods symmetrically spaced on the frame, a screw rod parallel to the guide rods, and a second motor connected to the screw rod; the base is sleeved on the guide rods and connected to the screw rod via a screw sleeve.
[0009] The aforementioned pull-out adhesive mixer includes a discharge frame located at the bottom of the cylinder, a valve plate arranged inside the discharge frame, a lever connected to the valve plate, a connecting plate located at one end of the lever, and a drive cylinder connected to the connecting plate and the frame; the drive cylinder drives the valve plate to rotate around the bottom of the cylinder via the lever.
[0010] In the aforementioned pull-out adhesive mixer, the shaft is a square rod.
[0011] In the aforementioned pull-out adhesive mixer, the paddle is mounted on a shaft via a plate holder, and the position of the plate holder on the shaft can be manually adjusted.
[0012] In the aforementioned pull-out adhesive mixer, the end of the drive cylinder is hinged to the frame, and the front end of the cylinder rod is hinged to the connecting plate.
[0013] The beneficial effects of this utility model are:
[0014] 1. Pull-out mixing component: The mixing component (base / shaft / paddle assembly) is pulled out horizontally by the drive component, so that the paddle is completely separated from the cylinder, thoroughly exposing the cleaning surface and eliminating the cleaning dead corners at the bottom of the cylinder and the back of the paddle.
[0015] 2. Flip-type unloading structure: The valve plate cooperates with the unloading frame to achieve full opening / full closing of the discharge port under the control of the drive cylinder; when the valve plate is closed horizontally, it fits the edge of the discharge port (with the sealing ring), and there is no structural obstruction to the flow of adhesive when flipping to unload, effectively reducing the residue rate.
[0016] 3. Dynamic stirring and adjustment mechanism: The paddles are adjustablely mounted on a square shaft via a plate base. The operator can manually adjust the working range of the paddles according to the viscosity of the adhesive. For high-viscosity adhesives, the paddle spacing can be reduced to enhance local shear force. For low-viscosity adhesives, the working range of the paddles can be expanded to avoid laminar flow zones, thereby reducing fluctuations in mixing uniformity. Attached Figure Description

[0026] The pull-out adhesive mixer involved in this embodiment is a device specifically designed for efficient mixing of adhesives, such as... Figure 1-7 As shown, the mixer mainly consists of key parts such as frame 1, cylinder 2, mixing assembly, and unloading assembly 5. These parts cooperate with each other to complete operations such as mixing the adhesive, unloading, and cleaning the equipment. Frame 1, as the basic support component of the entire mixer, is welded from high-strength steel and has sufficient rigidity and stability to withstand various loads generated during the operation of the mixer. The overall shape of frame 1 is a cuboid frame structure. The upper part of frame 1 has reserved installation positions for various components, providing reliable support and positioning for the installation of cylinder 2, mixing assembly, and unloading assembly 5.
[0027] The cylinder 2 is located at one end of the upper part of the frame 1 and is the main container for holding the adhesive to be mixed. The cylinder 2 is made of high-quality stainless steel, which has good corrosion resistance and wear resistance, and can adapt to the adhesive, which has a certain degree of viscosity and corrosiveness. The cylinder 2 is U-shaped, which is conducive to the flow and mixing of the adhesive during the stirring process, reduces the dead corners of the stirring, and improves the uniformity of the mixing. The top of the cylinder 2 is equipped with a removable cover plate with a feed port. The design of the feed port fully considers the convenience of feeding the adhesive. Its large size makes it convenient for operators to quickly and accurately add various adhesive raw materials into the cylinder 2. The cover plate and the cylinder 2 are connected by a sealed connection with a rubber sealing ring to prevent the adhesive from leaking during the stirring process. The removable design of the cover plate also provides great convenience for equipment maintenance and cleaning. When it is necessary to inspect or clean the inside of the cylinder 2, simply remove the cover plate for easy operation.
[0028] The mixing assembly is one of the core components of this mixer. Its function is to fully mix the adhesive inside the cylinder 2 to ensure the uniformity of the adhesive quality. The mixing assembly consists of a mixing component 3 and a driving component 4. The mixing component 3 is arranged on the side of the cylinder 2 and can be pulled out horizontally. This pull-out design has many advantages. On the one hand, during mixing, the mixing component 3 can be in close contact with the cylinder 2 to ensure the mixing effect. On the other hand, when it is necessary to clean the mixing component 3 or the inside of the cylinder 2, the mixing component 3 can be pulled out, which is convenient for operators to clean thoroughly. This avoids the problem of incomplete cleaning that exists in the traditional method of adding water from the feed inlet. The cleaning effect is more significant, especially for adhesives with high viscosity. The driving component 4 is arranged on the upper part of the frame 1 in the direction of pulling out the mixing component 3. It is used to support and pull the mixing component 3 to drive the contact and separation operation between the mixing component 3 and the cylinder 2.
[0029] The mixing component 3 specifically includes a base 31, a first motor 32, a shaft 33, a side plate 34, a paddle 35, and a plate base 36. The base 31 is located inside the frame 1 and serves as the support and installation foundation for the entire mixing component 3. The base 31 is made of cast iron, possessing high strength and stability. The base 31 can reciprocate along the length of the frame 1, and its movement trajectory is precisely controlled by the drive component 4 to ensure the stability and accuracy of the base 31 during movement. The first motor 32, as the power output component, is installed on the upper part of the base 31. The first motor 32 is a high-performance AC asynchronous motor, which has advantages such as high power, stable speed, and reliable operation. The lower end of the first motor 32 is bolted to the machine... The base 31 is fixedly connected, which is not only sturdy and reliable, but also facilitates the installation and disassembly of the motor. The output shaft of the first motor 32 is connected to the shaft 33 via a coupling. The coupling has good shock absorption and buffering effects, which can reduce the impact on the shaft 33 during motor start-up and operation, and extend the service life of the equipment. According to the actual speed requirements, a reducer can be added between the first motor 32 and the shaft 33. The function of the reducer is to convert the high-speed rotation of the first motor 32 into a low-speed rotation suitable for the shaft 33 to meet the process requirements of different adhesive mixing. The shaft 33 is placed horizontally inside the cylinder 2 and is a key component for transmitting power and installing the paddle 35. The shaft 33 is made of high-strength alloy steel and has undergone [further processing / construction]. The special heat treatment process gives it high hardness and toughness, enabling it to withstand large torque and bending stress. The shaft 33 is connected to the base 31 via a bearing housing. High-precision rolling bearings are used in the bearing housing to ensure stable and flexible rotation of the shaft 33. The shaft 33 is a square rod, which facilitates the fixing of the plate base 36. The four planes of the square rod provide stable support and positioning for the plate base 36, preventing it from sliding or rotating during shaft 33 rotation. The paddle 35 is the component that directly stirs the adhesive; its shape and size significantly affect the stirring effect. The paddle 35 is made of stainless steel with a polished surface to reduce adhesive adhesion. The paddle 35 is located on the shaft 31... 3. The upper part is arranged at intervals. The arrangement is optimized according to the characteristics of the adhesive and the requirements of the mixing process. One end of the paddle 35 is provided with a plate seat 36. The plate seat 36 abuts against the shaft 33 and is locked and fixed by bolts. The position of the plate seat 36 on the shaft 33 can be manually adjusted according to the mixing needs. In actual operation, the operator can flexibly adjust the position of the plate seat 36 according to factors such as the viscosity of the adhesive and the requirements for the uniformity of mixing, thereby changing the position of the paddle 35 in the cylinder 2 and the mixing range to achieve the best mixing effect. One end of the shaft 33 is also provided with a side plate 34 that can abut against the cylinder 2 to form a side sealing operation. The side plate 34 can be locked and fixed by flipping the clamp.
[0030] The drive unit 4 mainly consists of a second motor 41, a screw 42, and guide rods 43. The guide rods 43 are symmetrically and spaced along the upper length of the frame 1, providing guidance for the movement of the base 31. The guide rods 43 are made of high-quality carbon steel with a chrome-plated surface, exhibiting high hardness and wear resistance. The upper part of the guide rods 43 is fitted with a bushing that slides onto the base 31. The bushing is made of a self-lubricating material, reducing frictional resistance when the base 31 moves on the guide rods 43, thus improving the smoothness and accuracy of the movement. The screw 42 is located on the upper part of the frame 1 between the guide rods 43, with both ends connected to the frame 1 via bearing seats to ensure stable rotation. The screw 42 uses a trapezoidal thread, which offers advantages such as good self-locking performance and high transmission efficiency. A threaded sleeve is arranged below the base 31, meshing with the screw 42. The base 31 is connected to the second motor 41 by bolts. When the second motor 41 drives the screw 42 to rotate, the circumferential rotation of the screw 42 is converted into linear reciprocating motion of the base 31 along the surface of the guide rod 43 through the screw sleeve and guide rod 43. By controlling the forward and reverse rotation of the second motor 41, the base 31 can move forward or backward, thereby realizing the control of the contact and separation operation between the mixing component 3 and the cylinder 2. The second motor 41 is a servo motor, which has the advantages of high control accuracy and fast response speed. The second motor 41 is connected to the screw 42 through a reducer. The function of the reducer is to convert the high-speed rotation of the second motor 41 into the low-speed rotation of the screw 42 and provide sufficient torque to meet the movement requirements of the base 31. The control signal of the second motor 41 is issued by the control system. By precisely controlling the speed and direction of the motor, the precise control of the pulling motion of the mixing component 3 is realized.
[0031] The unloading assembly 5 is located at the top of the cylinder 2 and adopts a flap-type structure. It is used to control the unloading operation of the adhesive inside the cylinder 2. The unloading assembly 5 mainly consists of components such as the unloading frame 51, the drive cylinder 52, the connecting plate 53, the lever 54, and the valve plate 55. The unloading frame 51 is located at the bottom of the cylinder 2 and welded to it to provide support for the unloading operation. The unloading frame 51 is made of stainless steel and is square in shape. This shape facilitates the smooth flow of the adhesive during the unloading process. Inside the unloading frame 51, the lever 54 is arranged along the length direction. The lever 54 is connected to the unloading frame 51 through a bearing seat, which can... The lever 54 is capable of circumferential rotation. A valve plate 55 is connected to one side of the lever 54. The valve plate 55 and the lever 54 can be fixed by key connection or welding. The shape and size of the valve plate 55 match the discharge port at the bottom of the cylinder 2. When the valve plate 55 is in a horizontal position, it can completely block the discharge port to prevent adhesive leakage. When the valve plate 55 is flipped, the discharge port opens, and the adhesive can flow out smoothly. To improve the sealing performance, a sealing ring can be added around the valve plate 55 or the discharge port. The sealing ring is made of silicone rubber material, which has good elasticity and corrosion resistance. The sealing ring can be fixed by groove snap-fit or adhesive bonding. To ensure a tight fit when the valve plate 55 is closed and prevent adhesive leakage, a connecting plate 53 is welded to one end of the lever 54 to facilitate rotation. The connecting plate 53 is made of steel plate and has certain strength and rigidity. A drive cylinder 52 is arranged between the connecting plate 53 and the frame 1. The drive cylinder 52 can be a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder depending on the application. In this embodiment, a pneumatic cylinder is selected as the drive cylinder 52 because it has advantages such as simple structure, rapid action, and convenient maintenance. The end of the cylinder body of the drive cylinder 52 is hinged to the frame 1 through a pin, allowing the drive cylinder 52 to rotate around the pin. Position rotation; the front end of the cylinder rod of the drive cylinder 52 is hinged to the connecting plate 53 through a pin, so that the cylinder rod of the drive cylinder 52 and the connecting plate 53 can rotate around the pin position where they are connected. By the extension and retraction operation of the cylinder rod of the drive cylinder 52 inside the cylinder body, the connecting plate 53 is controlled to drive the lever 54 to rotate circumferentially around the bearing seat connected to the frame 1, thereby realizing the flipping operation of the valve plate 55. The drive cylinder 52 is connected to the frame 1 and the connecting plate 53 by a hinge. This connection method can effectively avoid jamming during the drive process and ensure that the valve plate 55 can be flipped flexibly and accurately.
[0032] When mixing the adhesive, the drive unit 4 is activated, and the second motor 41 drives the screw 42 to rotate. The screw 42 drives the base 31 to move forward along the guide rod 43 through the screw sleeve, so that the side plate 34 of the mixing unit 3 abuts against the cylinder 2. Then, the adhesive to be mixed is added into the cylinder 2 through the feed port at the top of the cylinder 2. The first motor 32 is activated, and the first motor 32 drives the shaft 33 to rotate. The paddle 35 on the shaft 33 stirs and mixes the adhesive in the cylinder 2. Depending on the viscosity of the adhesive, the operator can manually adjust the position of the plate seat 36 on the shaft 33 to improve the stirring effect. During the stirring process, the rotation of the paddle 35 causes the adhesive to continuously tumble and mix in the cylinder 2, ensuring that all components of the adhesive are fully and evenly mixed together. After the adhesive is mixed, the drive cylinder 52 of the unloading assembly 5 is activated. The cylinder rod of the drive cylinder 52 extends, driving the connecting plate 53 to rotate. The connecting plate 53 carries... Rotating lever 54 causes valve plate 55 to flip, opening the discharge port. The adhesive flows out from the discharge port at discharge frame 51 under its own gravity. During the discharge process, the flipping angle of valve plate 55 can be adjusted by controlling the movement speed of drive cylinder 52, thereby controlling the discharge speed of adhesive. When it is necessary to clean the mixing component 3 and the inside of cylinder 2, drive component 4 is activated to separate mixing component 3 from cylinder 2. After pulling out mixing component 3, the operator can use cleaning tools to thoroughly clean the paddle 35, shaft 33 and other components on mixing component 3. At the same time, the cover plate on the top of cylinder 2 is opened, and a high-pressure water gun or other cleaning equipment is used to clean the inside of cylinder 2. Since mixing component 3 can be pulled out, the cleaning personnel can easily clean every corner inside cylinder 2 to ensure that there is no adhesive residue inside the equipment and avoid contamination of the adhesive to be mixed in the next batch.
[0033] In summary, the pull-out adhesive mixer of this embodiment achieves efficient mixing of adhesives, convenient unloading, and thorough cleaning of the equipment through reasonable design and coordinated work between various components. This mixer has the advantages of compact structure, convenient operation, good mixing effect, and thorough cleaning, and has broad application prospects in the field of adhesive production.
