Description

Technical Field

[0001] This utility model relates to the field of filling mixer technology, and in particular to a quick-release structure for the mixing component of a filling mixer. Background Technology

[0002] Steamed buns, a traditional Chinese pastry, have seen rapid growth in the frozen food industry in recent years. As market demands for the quality and safety of steamed bun products increase, large-scale steamed bun manufacturers generally adopt automated production lines to complete processes such as dough processing, filling mixing, bun shaping, steaming, quick-freezing, and packaging. Among these processes, filling mixing is a crucial step affecting the taste and food safety of steamed buns, placing high demands on the stability, hygiene, and ease of cleaning of the mixing equipment.

[0003] Most existing filling mixers adopt a horizontal structure, with one or more mixing shafts inside. These shafts are equipped with propeller-type or blade-type mixing components, which are driven by a motor to rotate and mix various raw materials such as meat, vegetables, and seasonings. However, in actual use, the mixing shafts and blades adhere heavily to the filling, and the complex structure and limited space make cleaning extremely difficult. Especially during multi-product production, routine cleaning, or equipment maintenance, most existing mixing structures cannot be quickly disassembled, requiring operators to manually remove residual materials within a limited space. This is time-consuming, labor-intensive, and easily leaves unsanitary corners, posing a risk of cross-contamination.

[0004] Furthermore, some traditional designs use fixed welding or bolt connections between the stirring shaft and the housing, resulting in cumbersome disassembly and inconvenient operation, which hinders rapid equipment switching or regular deep cleaning. Given the trend in the frozen food industry towards high efficiency, cleanliness, and rapid production cycle changes, existing technologies still have significant room for improvement in terms of structural disassembly capabilities. Utility Model Content

[0005] The purpose of this invention is to solve the problems of inconvenient disassembly and difficulty in cleaning of the mixing components in the prior art, and to propose a quick-disassembly structure for the mixing components of a filling mixer.

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

[0007] A quick-release structure for a mixing assembly of a filling mixer includes a horizontal housing with two opposing side plates. One side plate is equipped with a power motor. Each side plate has a horizontally aligned connector rotatably connected to its inner side, and one connector is driven by the power motor. A mixing assembly is installed between the two side plates. The mixing assembly includes two support discs and multiple mixing rods located between the two support discs. The support discs are inserted into the connectors along their axial direction. The mixing rods are detachably assembled with the support discs, and the mixing rods can apply an outward thrust to the support discs, pointing towards the side plates.

[0008] The support plate has a slot on its outer circumference. The slot is located on the side of the support plate and is open on the outer circumference. Both ends of the stirring rod have mounting heads, which can be inserted into the slot through the open outer circumference of the support plate.

[0009] The mounting head has a quadrilateral radial cross section, and a ball-head plunger is mounted on the side of the mounting head. The support plate is provided with a limiting groove on the bayonet side wall to cooperate with the ball-head plunger.

[0010] The bayonet is tangentially inclined along the outer periphery of the support plate, and the bottom wall of the bayonet is located downstream of the open end of the outer periphery of the support plate.

[0011] The stirring rod includes a second limiting plate disposed at both ends of the main body. The second limiting plate abuts against the inner wall of the support plate. The connector includes a polygonal prism and a first limiting plate. The support plate is provided with a support cylinder along its axial direction. The support cylinder has a polygonal prism groove. The polygonal prism can be inserted into the polygonal prism groove, and the end face of the support cylinder abuts against the first limiting plate.

[0012] The second limiting plate has a chamfered part on the side near its corresponding support plate.

[0013] The stirring rod includes a main stirring shaft, and several stirring support rods are fixedly connected to the periphery of the main stirring shaft.

[0014] The present invention proposes a quick-disassembly structure for the mixing component of a filling mixer, which has the following advantages: On the one hand, this device can easily clean the disassembled mixing component, and on the other hand, it can clean the inside of the horizontal housing. This solves the problems of difficult cleaning of mixing components and inconvenient disassembly and assembly in traditional filling mixers, and improves the hygiene controllability and maintenance efficiency of the equipment in actual production. It is especially suitable for frozen food enterprises that produce multiple categories and require frequent cleaning. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4 A quick-release structure for a mixing assembly of a filling mixer includes a horizontal housing with two opposing side plates 2. One side plate 2 is equipped with a power motor 1. Each side plate 2 has a horizontally oriented connector 4 rotatably connected to its inner side. One connector 4 is connected to the power motor 1. A mixing assembly 3 is installed between the two side plates 2. The mixing assembly 3 includes two support plates 15 and multiple mixing rods 18 located between the two support plates 15. The support plates 15 are inserted into the connectors 4 along their axial direction. The mixing rods 18 are detachably assembled with the support plates 15 and can apply a pushing force to the support plates 15 outwards towards the side plates 2.

[0022] When in operation, the motor drives the connected connector to rotate, thereby driving the entire mixing assembly to tumble and mix the filling.

[0023] When disassembly and cleaning are required, first remove the stirring rod 18 from the support plate 15. Since the support plate 15 is no longer restricted by the thrust in the axial direction of the stirring rod 18, the support plate 15 can be quickly removed from the connector 4, thereby completing the disassembly of the stirring assembly 3. The stirring rod is located between the two support plates, evenly arranged and detachably connected to the support plates at its end. This allows the stirring rod to not only undertake the stirring task during operation, but also to stably press the two support plates against the connectors at both ends of the box through axial thrust, forming a complete stirring structure.

[0024] This device can easily clean the disassembled mixing component 3 and the interior of the horizontal housing, solving the problems of difficult cleaning of mixing components and inconvenient disassembly and assembly in traditional filling mixers. It improves the hygiene controllability and maintenance efficiency of the equipment in actual production, and is especially suitable for frozen food enterprises that produce multiple categories and require frequent cleaning.

[0025] The support plate 15 has a bayonet 13 on its outer circumference. The bayonet 13 is open on the side and outer circumference of the support plate 15. Both ends of the stirring rod 18 have mounting heads 11, which can be inserted into the bayonet 13 through the open outer circumference of the support plate 15. This structure, by setting an open bayonet on the outer circumference of the support plate, makes the installation and removal of the stirring rod more convenient. The stirring rod has mounting heads at both ends, which can be directly inserted into the bayonet through the open portion of the support plate's outer circumference during installation to achieve a mating connection with the support plate. Because the bayonet is an open structure, the operator does not need to completely remove the support plate during assembly; simply inserting the mounting head from the outside completes the connection, eliminating the complex steps of internal embedding, screwing, or bolting fixation in traditional structures.

[0026] The mounting head 11 has a quadrilateral radial cross-section, and a ball-head plunger 12 is mounted on the side of the mounting head 11. The support plate 15 has a limiting groove 14 on the side wall of the bayonet 13 that mates with the ball-head plunger 12. This structure, with a ball-head plunger on the side of the mounting head and a limiting groove on the side wall of the bayonet of the support plate, forms a reliable automatic positioning and locking structure. During installation, the mounting head, with its quadrilateral cross-section, is inserted into the bayonet from the opening of the support plate. When it is pushed to the predetermined position, the ball-head plunger automatically engages in the limiting groove under the action of elasticity, completing positioning and initial locking. Utilizing the elastic clamping characteristic of the ball-head plunger, automatic engagement and positioning are achieved during insertion, ensuring that the stirring rod does not loosen or slip during operation, while also facilitating quick release by pushing it out with slight external force during disassembly.

[0027] The bayonet 13 is tangentially inclined along the outer periphery of the support plate 15. The bottom wall of the bayonet 13 is located downstream of the open end of the outer periphery of the support plate 15. Counterclockwise rotation is defined as the working state. (Refer to...) Figure 4 This structure cleverly combines the relationship between the direction of stirring motion and structural stability by setting the bayonet tangentially along the outer periphery of the support plate and placing the bottom wall of the bayonet downstream of the open end. Under the premise of defining counterclockwise as the working rotation direction, the filling will generate a certain reverse force on the stirring rod during stirring, and this force is guided to the bottom wall area of ​​the bayonet along the rotation direction.

[0028] Because the locking mechanism is angled, the force exerted by the filling on the stirring rod does not push it out of the locking mechanism; instead, it causes it to press more tightly against the bottom wall of the locking mechanism, thus providing a self-locking and anti-detachment structural function in actual operation. This design effectively solves the problem of the stirring rod loosening or detaching under high load and high frequency of movement.

[0029] The stirring rod 18 includes a second limiting plate 9 disposed at both ends of the main body. The second limiting plate 9 abuts against the inner wall of the support plate 15. The connector 4 includes a polygonal prism 5 and a first limiting plate 6. The support plate 15 is provided with a support cylinder 16 along its axial direction. The support cylinder 16 has a polygonal prism groove 17. The polygonal prism 5 can be inserted into the polygonal prism groove 17, and the end face of the support cylinder 16 abuts against the first limiting plate 6.

[0030] This structure incorporates second limiting plates at both ends of the stirring rod, enabling it to form a surface contact fit with the inner wall of the support plate during assembly. During installation, after the stirring rod is inserted into the support plate, the second limiting plates adhere tightly to the inner surface of the support plate. As multiple stirring rods are sequentially installed, an outward pushing force is applied to the support plate in the axial direction, ensuring the support plate remains firmly against the connector, forming a stable assembly. Simultaneously, the connector features a polygonal prism structure, and the axially positioned support cylinder of the support plate has a matching polygonal prism groove. When these two are inserted, they form an anti-rotation fit, effectively ensuring the coaxial rotation and torque transmission capability of the stirring assembly during transmission. The end face of the support cylinder further abuts against the first limiting plate, ensuring that the assembly does not experience axial displacement during operation.

[0031] The second limiting plate 9 has a chamfered part 10 on the side near the corresponding support plate 15. The chamfered part 10 is provided so that when the mounting head 11 is inserted into the bayonet 13, the second limiting plate 9 can cut into and abut against the support plate 15 better.

[0032] The stirring rod 18 includes a main stirring shaft 7, and several stirring support rods 8 are fixedly connected to the periphery of the main stirring shaft 7. Furthermore, a stirring plate can be provided at the end of the stirring support rod 8 to enhance the stirring effect.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
