Description

Technical Field

[0001] This utility model belongs to the field of dough mixer technology, and specifically relates to a dough mixer with an easy-to-disassemble auger. Background Technology

[0002] A dough mixer is a type of noodle-making machinery. Its main function is to mix flour and water evenly, forming a dough with a certain degree of elasticity, stretchability, and uniform flow.

[0003] Most commercially available dough mixers use a drive unit to rotate an auger, which then mixes flour and water evenly. For example, Chinese utility model patent CN 202122001411.0 discloses a dough mixer shaft end sealing structure, which includes a housing. A rotating shaft is located inside the housing, and the shaft body within the housing has spiral blades. Both ends of the rotating shaft pass through through holes on the side plates of the housing. A connecting plate is sleeved on the shaft end, connecting to the housing. The inner ring of the connecting plate has a graphite packing root adapted to the shaft body. The end face of the connecting plate away from the housing has a pressure plate that can press the graphite packing root, and the pressure plate is adapted to the rotating shaft. A seated spherical bearing is also connected to the end face of the connecting plate away from the housing via bolts and nuts.

[0004] In the above structure, the main body of the rotating shaft is an integral structure. When the rotating shaft needs to be disassembled for maintenance, the user needs to disassemble the rotating shaft from the housing, pressure plate and connecting plate. Since the two ends of the rotating shaft pass through the two sides of the housing respectively, the housing needs to be disassembled during the disassembly process, which is inconvenient for the user to disassemble and maintain. In addition, frequent disassembly and installation can easily affect the sealing of the housing and affect the normal use of the dough mixer. Summary of the Invention

[0018] The advantages of this utility model compared to the prior art are:

[0019] 1. The auger in this utility model includes a detachably connected first hinge rod, a second hinge rod, and an auger body. The first and second hinge rods are respectively located on both sides of the material bucket and inserted into the material bucket. When the auger needs to be disassembled for maintenance or cleaning, the user only needs to disassemble the auger body from the first and second hinge rods, which facilitates the assembly, production, disassembly, and maintenance of the dough mixer. The user can also clean the auger body after disassembly, which helps to keep the dough mixer clean and hygienic. The grooves and protrusions can prevent axial movement between the auger body and the first or second hinge rod, which facilitates the positioning and installation of the auger body. It also prevents misalignment between the auger body and the first or second hinge rod during use, which could affect the disassembly and installation of fasteners or even cause damage to the fasteners, thus facilitating the assembly, production, disassembly, and maintenance of the dough mixer.

[0020] 2. The limiting groove in this utility model facilitates the user's control over the disassembly and installation of bolts and nuts, making it convenient for the assembly, production, disassembly, and maintenance of the dough mixer.

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0037] See Figures 1 to 9 As shown, a dough mixer with an easily detachable auger includes a frame 1, a material bin 3 mounted on the frame 1, an auger 6 rotatably mounted within the material bin 3, and a drive device 2 mounted on the frame 1 for driving the auger 6 to rotate. The auger 6 includes a first hinge rod 61 and a second hinge rod 62 rotatably connected to the frame 1. The first hinge rod 61 and the second hinge rod 62 are respectively located on both sides of the material bin 3 and pass through the material bin 3. An auger body 63 is disposed between the first hinge rod 61 and the second hinge rod 62. Fasteners 64 are provided on the side of the auger body 63, and the fasteners 64 control the auger body 63 to be detachably connected to the first hinge rod 61 and the second hinge rod 62. The connection is detached, and the drive device 2 drives the first hinge rod 61 or the second hinge rod 62 to move and drive the auger body 63 to rotate. In this structure, the auger 6 includes a detachably connected first hinge rod 61, second hinge rod 62 and auger body 63. The first hinge rod 61 and the second hinge rod 62 are respectively set on both sides of the material tank 3 and inserted into the material tank 3. When the auger 6 needs to be disassembled for maintenance or cleaning, the user only needs to detach the auger body 63 from the first hinge rod 61 and the second hinge rod 62, which facilitates the assembly, production and disassembly maintenance of the dough mixer. The user can also disassemble the auger body 63 for cleaning, which helps to keep the dough mixer clean and hygienic.

[0038] The auger body 63 has a first connecting portion 631 at both ends, and a second connecting portion 611 on both the first hinge rod 61 and the second hinge rod 62. A fastener 64 passes through the first connecting portion 631 and the second connecting portion 611 and fixes the auger body 63 to the first hinge rod 61 or the second hinge rod 62. A groove 632 and a protrusion 614 are respectively provided on opposite sides of the first connecting portion 631 and the second connecting portion 611, and the groove 632 and the protrusion 614 fit together in a limited manner. The axial movement of the auger body 63 and the first hinge rod 61 or the second hinge rod 62 is prevented. The groove 632 and the protrusion 614 can prevent the axial movement of the auger body 63 and the first hinge rod 61 or the second hinge rod 62, which facilitates the positioning and installation of the auger body 63. It also prevents the auger body 63 and the first hinge rod 61 or the second hinge rod 62 from being misaligned during use, which could affect the disassembly and installation of the fastener 64 or even cause damage to the fastener 64. This facilitates the assembly, production and disassembly maintenance of the dough mixer.

[0039] In this embodiment, the driving device 2 includes a drive motor 21 and a transmission structure 22. A transmission part 621 is provided on the second hinge rod 62. The transmission structure 22 cooperates with the transmission part 621 and drives the auger 6 to rotate through the transmission part 621.

[0040] Preferably, the cross-sections of the groove 632 and the protrusion 614 can be rectangular, trapezoidal, or arc-shaped. In this embodiment, the cross-sections of the groove 632 and the protrusion 614 are both trapezoidal, and the size of the cross-section of the groove 632 increases with the distance from the bottom of the groove 632. The trapezoidal cross-sections of the groove 632 and the protrusion 614 facilitate quick disassembly and installation, making it convenient for the assembly, production, disassembly, and maintenance of the dough mixer.

[0041] The first connecting part 631 or the second connecting part 611 is provided with a limiting groove 633 on its side. The fastener 64 includes a bolt 641 and a nut 642. One end of the bolt 641 is housed in the limiting groove 633 and the relative rotation between the bolt 641 and the auger body 63 is restricted. The setting of the limiting groove 633 makes it convenient for the user to control the disassembly and installation of the bolt 641 and the nut 642, which facilitates the assembly, production and disassembly maintenance of the dough mixer. Moreover, this structure helps to reduce the protrusion of the bolt 641 from the side of the auger 6 and reduce the dough residue on the auger 6. In this embodiment, the first connecting part 631 and the second connecting part 611 are provided with a through hole 615. The bolt 641 passes through the through hole 615, and the limiting groove 633 is provided at one end of the through hole 615.

[0042] In this invention, the first connecting part 631 and the groove 632 at both ends of the auger body 63 have the same cross-section and are symmetrically arranged. The protrusions 614 on the first hinge rod 61 and the second hinge rod 62 can both cooperate with the grooves 632 at both ends of the auger body 63. Since the first connecting part 631 and the groove 632 at both ends of the auger body 63 have the same cross-section and are symmetrically arranged, the auger body 63 can be installed upright or in reverse during use, which is convenient for users to install flexibly and facilitates the quick assembly of the dough mixer.

[0043] In this embodiment, the groove 632 and the protrusion 614 cooperate to form a cylindrical structure by combining the first connecting part 631 and the second connecting part 611. This structure avoids the residue of dough at the connection position of the first connecting part 631 and the second connecting part 611 during use, making it convenient for users to use and clean the auger 6.

[0044] The material bucket 3 is rotatably mounted on the frame 1. The frame 1 is provided with a limiting member 7 that controls the relative fixation of the material bucket 3 and the frame 1. A flip cover 4 is movably mounted on the frame 1. The flip cover 4 can be fastened to the material bucket 3 and restrict the relative rotation of the material bucket 3 and the frame 1. The material bucket 3, which is rotatably mounted on the frame 1, makes it easy for the user to take out the kneaded dough. The flip cover 4 can not only prevent foreign matter from entering the material bucket 3 during the kneading process, but also restrict the relative rotation of the material bucket 3 and the frame 1, which is conducive to the stable installation of the material bucket 3 and prevents the material bucket 3 from tilting and flipping during the kneading process.

[0045] The material bucket 3 described in this utility model is provided with a connecting buckle 5, and the flip cover 4 is provided with a hook 43 that matches the connecting hole. The connecting buckle 5 and the hook 43 cooperate to keep the flip cover 4 connected to the material bucket 3. The setting of the connecting buckle 5 and the hook 43 is conducive to the stable connection between the material bucket 3 and the frame 1, and avoids the material bucket 3 tilting and flipping during the kneading process.

[0046] In this embodiment, the flip cover 4 is rotatably mounted on the frame 1 via a hinge 41, and a handle is provided on the flip cover 4, which the user can control to rotate the flip cover 4.

[0047] Rotating seats 31 are respectively provided on both sides of the material bucket 3, and mounting seats 11 rotatably connected to the rotating seats 31 are provided on the frame 1. The first hinge rod 61 and the second hinge rod 62 are respectively rotatably arranged in the rotating seats 31 on both sides of the material bucket 3 and can rotate relative to the frame 1 through the rotating seats 31. The arrangement of the rotating seats 31 and the mounting seats 11 is conducive to the stable installation of the material bucket 3, avoids the first hinge rod 61 and the second hinge rod 62 from being damaged by excessive force, and helps to extend the service life of the dough mixer.

[0048] The rotating seat 31 of this utility model is provided with an installation groove 311 facing the material bucket 3. A bearing 32 is provided in the installation groove 311. The first hinge rod 61 and the second hinge rod 62 are each provided with a hinge part 612 and a limiting wall 613. The hinge part 612 is adapted to the inner shell of the bearing 32, and the limiting wall 613 abuts against the bearing 32 and makes the bearing 32 press against the bottom of the installation groove. The installation groove 311 facing the material bucket 3 is convenient to limit the overall length of the auger 6, and prevent the first hinge rod 61 and the second hinge rod 62 from shifting to both sides of the material bucket 3 after long-term use. It is also beneficial to the positioning connection between the auger body 63 and the first hinge rod 61 and the second hinge rod 62, and facilitates the quick installation and disassembly of the auger body 63.

[0049] In this embodiment, the rotating seat 31 and the material bucket 3 are detachably connected. The side of the material bucket 3 is provided with a through hole 34. The first hinge rod 61 or the second hinge rod 62 passes through the through hole 34 and is connected to the rotating seat 31.
