Description

Technical Field

[0001] This utility model belongs to the technical field of food processing equipment, and relates to an adjustable angle mixing device for mixing broad bean paste with stir-fried seasonings. Background Technology

[0002] In the processing of broad bean paste products, the uniformity of mixing of broad bean paste with stir-fried seasonings directly affects product quality. Existing mixing equipment mostly adopts a fixed-angle stirring structure. Since the humidity and particle size of broad bean paste vary at different processing stages, a fixed angle is difficult to adapt to the mixing requirements of materials in different states, which easily leads to problems such as insufficient mixing and many dead corners of local accumulation. Traditional mixing cylinders are mostly circular cavities. The materials inside the cylinder are easily formed into a stable circulation due to centrifugal force, resulting in the seasonings being distributed only on the surface of the materials, which cannot achieve deep mixing and greatly reduces mixing efficiency.

[0003] Furthermore, the transmission mechanisms of existing equipment generally adopt single belt drives. During long-term high-load operation, the belt is prone to slippage due to uneven tension, which not only affects the transmission accuracy and production continuity, but also generates dust and contaminates materials due to friction. At the same time, the angle adjustment structure of traditional equipment is mostly gear meshing type, which is cumbersome to adjust and has low positioning accuracy, making it difficult to meet the needs of precision production. In addition, the existing mixing drum is difficult to clean and maintain, and residual materials on the inner wall are prone to bacterial growth, affecting the hygiene and quality of the product. Therefore, in order to solve the above technical problems, the technical solution of this application is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the problems of insufficient mixing, non-adjustable angle, and poor transmission stability in existing broad bean paste mixing equipment. This utility model provides a broad bean paste mixing equipment with an adjustable angle, which achieves the goals of adjustable mixing angle, uniform material mixing, and stable transmission by optimizing the equipment structure design.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An adjustable angle broad bean paste mixing device includes a base, a vertically arranged support platform fixedly connected to the base, support seats symmetrically installed on both sides of the upper end face of the support platform, and an adjustable angle fixed platform between the support seats. The two sides of the fixed platform are rotatably connected to the support seats through a rotating shaft.

[0007] The support base has locking structures on both sides for locking and adjusting the angle of the fixed platform. The locking structure includes an arc-shaped adjustment groove on the side of the support base and a locking bolt that passes through the arc-shaped adjustment groove. The end of the locking bolt is threaded to the side of the fixed platform.

[0008] A rotating shaft is rotatably connected to the front end face of the fixed platform, and a mixing cylinder is fixedly connected to the front end face of the rotating shaft. The mixing cylinder has a polygonal cavity structure with an opening at its front end face.

[0009] A driven wheel groove is fixedly installed on the rotating shaft, a drive motor is fixedly installed on one side of the support platform, and a driving wheel groove is fixedly installed on the drive shaft of the drive motor. The driving wheel groove and the driven wheel groove are connected by at least two belts.

[0010] The working principle of this utility model is as follows: During operation, firstly, according to the mixing requirements of broad bean paste and seasonings, the locking bolts are loosened, and the fixed platform is rotated to the required angle along the arc-shaped adjustment groove of the support base. Then, the locking bolts are tightened to complete the angle fixation. The broad bean paste to be mixed and the stir-fried seasonings are put into the mixing cylinder through the front opening, and the sealing cover is closed. The drive motor is started, and the drive motor drives the active wheel groove to rotate through the drive shaft. The active wheel groove transmits power to the driven wheel groove through two belts. The driven wheel groove drives the rotating shaft and the mixing cylinder to rotate synchronously.

[0011] Because the mixing drum is a polygonal cavity with stirring ribs on the inner wall, the material is constantly folded, collided and mixed during rotation due to the obstruction of the cavity's corners and the pushing action of the stirring ribs. At the same time, the adjustable angle of the mixing drum allows the material to flow along the inclined direction under the action of gravity, further eliminating mixing dead corners and ultimately achieving a thorough and uniform mixture of broad bean paste and seasonings. After mixing is completed, the drive motor is turned off and the sealed cover is opened to remove the mixed material.

[0012] Furthermore, several axially arranged protruding stirring ribs are evenly distributed on the inner wall of the polygonal cavity. This design is to enhance the mixing effect of the materials. When the mixing drum rotates, in addition to the material being obstructed by the edges of the polygonal cavity and undergoing folding motion, the stirring ribs will generate additional disturbance to the material. The stirring ribs with different cross-sections such as triangles and semicircles can form different contact and pushing methods with the material, increasing the collision frequency and force between the materials, effectively preventing the material from forming a stable circulation in the drum, further improving the uniformity of the mixing of broad bean paste and seasonings, and solving the problem that the mixing effect of traditional mixing drums is limited by the shape of the cavity alone.

[0013] Furthermore, a detachable sealing cap with a snap-fit ​​structure is connected to the front opening of the mixing drum. The main purpose is to prevent material splashing during the mixing process. The snap-fit ​​structure features a firm connection and convenient operation, allowing operators to quickly close and open the sealing cap. The sealing cap ensures that the materials are mixed in a closed space, avoiding waste caused by splashing and pollution of the surrounding environment. It also reduces the entry of external impurities into the mixing drum, ensuring the hygienic quality of the materials and meeting the hygiene requirements of food processing.

[0014] Furthermore, the center of the arc-shaped adjustment groove coincides with the axis of rotation of the fixed platform. This design ensures that the locking bolt can always move smoothly within the arc-shaped adjustment groove during the angle adjustment process, ensuring the stability and accuracy of the angle adjustment. The angle adjustment range of 0°-60° is determined according to the mixing requirements of broad bean paste under different humidity and particle size conditions. Smaller angles are suitable for drier materials, which can reduce the material flow rate; larger angles are suitable for wetter or slightly stickier materials, which can use gravity to promote material flow and avoid accumulation, enabling the equipment to adapt to the mixing requirements of materials with different characteristics.

[0015] Furthermore, a non-slip handle is provided on the head of the locking bolt, making it convenient for operators to manually tighten the bolt without the need for additional tools, thus improving the ease of angle adjustment, especially saving operation time when the angle is frequently adjusted on the production site; a wear-resistant shim is provided between the locking bolt and the arc-shaped adjustment groove, which can reduce the direct friction between the bolt and the adjustment groove, reduce the wear rate of the components, extend the service life of the locking structure, and ensure the reliability of angle adjustment and fixation after long-term use.

[0016] Furthermore, the drive pulley groove and driven pulley groove adopt V-grooves, which are used in conjunction with polyurethane synchronous belts. The V-grooves can increase the contact area and friction between the belt and the pulley groove, improve transmission efficiency, and reduce slippage. The polyurethane synchronous belt has good wear resistance, tensile strength, and stability. Compared with ordinary rubber belts, it has higher transmission accuracy and longer service life, which can ensure the stable transmission of power from the drive motor to the mixing drum, ensure the transmission reliability of the equipment during long-term high-load operation, and avoid production interruptions caused by belt problems.

[0017] Furthermore: A motor bracket with a slotted hole is installed on the side of the support platform, and the drive motor is fixed to the motor bracket with bolts; the slotted hole design allows the height of the drive motor to be adjusted during installation and use. By adjusting the motor height, the relative position between the drive pulley groove and the driven pulley groove can be changed, thereby adjusting the belt tension; proper belt tension is the key to ensuring stable transmission. Too loose a belt will easily slip, while too tight a belt will increase the motor load and component wear. The slotted hole structure provides a convenient and effective way to adjust the belt tension, facilitating the installation, commissioning, and subsequent maintenance of the equipment.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. An adjustable angle broad bean paste mixing device, which achieves flexible adjustment of the fixed platform angle by setting an arc-shaped adjustment groove and a locking structure composed of locking bolts on both sides of the support base. The tilt angle of the mixing cylinder can be adjusted according to the material characteristics, effectively avoiding dead corners of material accumulation and improving the mixing uniformity.

[0020] 2. In this utility model, a mixing cylinder with a polygonal cavity structure is used in conjunction with stirring ribs on the inner wall. When the mixing cylinder rotates, the material forms a folding motion at the corners of the polygonal cavity. Combined with the disturbance effect of the stirring ribs, the collision and mixing effect between materials is significantly enhanced, solving the circulation problem of traditional circular mixing cylinders.

[0021] 3. In this utility model, the drive pulley groove and the driven pulley groove are connected by at least two belts, which effectively improves the transmission stability, avoids belt slippage, and ensures continuous and stable operation of the equipment compared with single belt drive.

[0022] 4. In this utility model, the sealing cap prevents material from splashing during mixing, and the snap-fit ​​structure facilitates quick loading and unloading; the waist-shaped hole design of the motor bracket makes it easy to adjust the belt tension, further optimizing the transmission performance.

[0029] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0030] Example 1

[0031] This utility model relates to an adjustable-angle broad bean paste mixing device, such as... Figure 1 As shown, it includes a base 1, on which a vertically arranged support platform 2 is fixedly connected. Support seats 3 are symmetrically installed on both sides of the upper end face of the support platform 2. An adjustable fixed platform 4 is provided between the support seats 3. The two sides of the fixed platform 4 are rotatably connected to the support seats 3 through a rotating shaft 5.

[0032] The support base 3 is provided with locking structures on both sides for locking and adjusting the angle of the fixed platform 4. The locking structure includes an arc-shaped adjustment groove 6 opened on the side of the support base 3 and a locking bolt 7 passing through the arc-shaped adjustment groove 6. The end of the locking bolt 7 is threaded to the side of the fixed platform 4.

[0033] A rotating shaft 8 is rotatably connected to the front end face of the fixed platform 4, and a mixing cylinder 9 is fixedly connected to the front end face of the rotating shaft 8. The mixing cylinder 9 has a polygonal cavity structure and its front end face is open.

[0034] A driven wheel groove 10 is fixedly installed on the rotating shaft 8, and a drive motor 11 is fixedly installed on one side of the support platform 2. A driving wheel groove 12 is fixedly installed on the drive shaft of the drive motor 11. The driving wheel groove 12 and the driven wheel groove 10 are connected by at least two belts 13.

[0035] The inner wall of the mixing cylinder 9 is evenly distributed with several raised stirring ribs 14, which are arranged along the axial direction of the mixing cylinder 9.

[0036] A sealing cover 15 is detachably connected to the front opening of the mixing drum 9. The edge of the sealing cover 15 is provided with a snap-fit ​​structure that matches the opening of the mixing drum 9.

[0037] The center of the arc-shaped adjustment groove 6 coincides with the axis of rotation 5 of the fixed platform 4, and the angle adjustment range of the arc-shaped adjustment groove 6 is 0°-60°.

[0038] The head of the locking bolt 7 is provided with an anti-slip handle 16, and a wear-resistant pad 17 is provided between the locking bolt 7 and the arc-shaped adjustment groove 6.

[0039] Both the drive pulley groove 12 and the driven pulley groove 10 have V-shaped grooves, and the belt 13 is a polyurethane synchronous belt.

[0040] A motor bracket 18 is fixedly installed on the side of the support platform 2. The drive motor 11 is fixed to the motor bracket 18 by bolts. The motor bracket 18 has an oblong hole 19 for adjusting the height of the drive motor 11.

[0041] The specific implementation method of this embodiment is as follows: the base is made of cast iron, which has good rigidity and shock absorption performance, and can provide a stable support foundation for the entire equipment; the bottom of the base is fixed to the ground with expansion bolts to ensure that the equipment will not shake or shift during operation; a vertically set support platform is welded on the base, and the support platform is a steel plate bending and forming structure with a steel plate thickness of 10mm. This structural design not only ensures the strength of the support platform, but also reduces the overall weight of the equipment.

[0042] Support seats are symmetrically installed on both sides of the upper end face of the support platform by bolts. The support seats are made of cast steel, which has high strength and toughness and can withstand the force generated when the fixed platform and mixing cylinder rotate. The opposite sides of the support seats have shaft holes for mating with the rotating shaft of the fixed platform. A fixed platform is provided between the support seats. The fixed platform has rotating shafts integrally formed on both sides. The rotating shafts and the shaft holes of the support seats are clearance-fitted. This fit allows the fixed platform to rotate flexibly around the rotating shaft and adjust the angle.

[0043] The support base has locking structures on both sides, including arc-shaped adjustment grooves on the sides of the support base and locking bolts passing through the arc-shaped adjustment grooves. The center of the arc-shaped adjustment grooves coincides with the axis of the rotating shaft. This design ensures that the locking bolts can always move within the arc-shaped adjustment grooves when the fixed platform is rotated to adjust the angle. The angle adjustment range is 0°-45°, which can meet the basic angle requirements when mixing different materials. The end of the locking bolts is threaded to the threaded holes on the side of the fixed platform. By tightening or loosening the locking bolts, the angle of the fixed platform can be fixed and adjusted. The head of the locking bolts is welded with anti-slip handles. The anti-slip handles make it convenient for operators to manually tighten the locking bolts and prevent slippage during operation. A brass wear-resistant washer is fitted between the locking bolts and the arc-shaped adjustment grooves. Brass has good wear resistance, which can reduce friction between the locking bolts and the arc-shaped adjustment grooves and extend the service life of the equipment.

[0044] The front end of the fixed platform is rotatably connected to a rotating shaft via a bearing seat. The bearing seat ensures the rotating shaft can rotate flexibly and reduces frictional resistance during rotation. The front end of the rotating shaft is fixedly connected to a mixing cylinder via a flange. The flange connection method has the advantages of strong connection and easy disassembly, facilitating the maintenance and replacement of the mixing cylinder. The mixing cylinder has a regular hexagonal cavity structure, welded from 304 stainless steel plate. 304 stainless steel has good corrosion resistance and hygiene properties, meeting the requirements of food processing equipment. Its front end is open for easy material input and output. The inner wall of the mixing cylinder is evenly welded with four raised stirring ribs. The stirring ribs have a triangular cross-section and are arranged along the axial direction of the mixing cylinder. The stirring ribs can disturb the material during the rotation of the mixing cylinder, enhancing the mixing effect.

[0045] A sealing cap is connected to the front opening of the mixing drum via a hinge, which allows the sealing cap to open and close flexibly. The edge of the sealing cap has a snap-fit ​​structure that fits the opening of the mixing drum, which can tightly close the sealing cap at the opening of the mixing drum to prevent materials from splashing out during the mixing process.

[0046] A driven pulley groove is fixedly mounted on the rotating shaft via a key connection. This key connection method offers advantages such as high torque transmission and reliable connection. A motor bracket is welded to one side of the support platform. The motor bracket is a welded steel plate structure with sufficient strength to support the drive motor. The drive motor is bolted to the motor bracket, which has a slotted hole for adjusting the height of the drive motor, thereby adjusting the belt tension. A drive pulley groove is fixedly mounted on the drive shaft of the drive motor via a key connection. Both the drive and driven pulley grooves are V-shaped grooves, providing a large contact area with the belt and strong torque transmission capability. The two are connected by two polyurethane synchronous belts. Polyurethane synchronous belts offer advantages such as high transmission efficiency, low noise, and good wear resistance, ensuring stable power transmission.

[0047] Example 2

[0048] This utility model relates to an adjustable-angle broad bean paste mixing device, such as... Figure 1 As shown, the specific implementation method of this embodiment is as follows:

[0049] The difference between this embodiment and Embodiment 1 is that the mixing cylinder adopts an octagonal cavity structure. Compared with the regular hexagonal cavity structure, the octagonal cavity allows the material to tumble and collide more fully inside the cylinder, further improving the mixing effect. The stirring ribs on its inner wall have a semi-circular cross-section. The semi-circular cross-section of the stirring ribs is gentler when disturbing the material, reducing the crushing effect on the material. In addition, the stirring ribs are spirally distributed along the circumference of the mixing cylinder. The spiral stirring ribs can generate an axial pushing force on the material during the rotation of the mixing cylinder, so that the material can flow axially while mixing, improving the uniformity of mixing.

[0050] The angle adjustment range of the arc-shaped adjustment groove is 0°-60°, and the larger angle adjustment range can adapt to the mixing needs of more materials with different properties; the drive wheel groove and the driven wheel groove are connected by three rubber synchronous belts. Compared with two synchronous belts, three synchronous belts can transmit greater torque, further improving the stability and reliability of the transmission.

[0051] In addition, a silicone sealing gasket is pasted on the inside of the sealing cover. The silicone sealing gasket has good sealing and elasticity, which can further enhance the sealing effect between the sealing cover and the opening of the mixing cylinder, preventing materials from leaking out from the gaps during the mixing process. The drive motor is a servo motor, which has the advantages of wide speed range and high control precision. The rotation speed can be adjusted by the controller to adapt to the mixing needs of different materials and improve the versatility of the equipment.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions and improvements made by those skilled in the art within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
