Description

Technical Field

[0001] This invention generally relates to the field of food machinery, and more particularly to a dough-making machine. Background Technology

[0002] A dough mixer is a type of food processing machine. Its main function is to evenly mix flour and water to form a dough for later use. The overhead dough mixer is one such type. Dough mixers are common kitchen appliances used in many households for making pasta or cakes, and are widely popular.

[0003] The tilting function of a dough mixer (for easy replacement of parts and placement of ingredients) generally has the following locking methods: upper and lower rocker locking, rotary linkage locking, and button locking. These locking mechanisms are all located away from the edge of the column (near the center of the column), resulting in generally weak locking force. This can cause the upper body to wobble and become unstable during operation. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a locking and stable head-up and dough-making machine.

[0005] In a first aspect, the present invention provides a dough-making machine comprising a lower body, an upper body, a column, and a material hopper. The column is fixed to the lower body, and the material hopper is placed on the lower body. The column is located between the upper body and the lower body. The upper body is rotatably connected to the column. A plurality of locking blocks are detachably fixed to the side of the column facing the material hopper. The side of the upper body facing the locking blocks has a through hole through which the locking blocks pass. A locking rod is rotatably connected to the upper body. The locking blocks are provided with locking grooves. The locking rod is provided with a plurality of locking parts that cooperate with the locking grooves, and each locking part corresponds one-to-one with the locking groove.

[0006] Lower the upper body, the locking block passes through the through hole, rotate the locking rod, and drive the multiple locking parts to be respectively placed into the corresponding locking grooves, so that the upper body and the column are in a locked state. At this time, the upper body is close to the column.

[0007] Rotate the locking rod to disengage the locking part from the locking groove, so that the upper body and the column are in an unlocked state. At this time, the upper body can rotate relative to the column.

[0008] According to the technical solution provided in the embodiments of this application, the locking block is set on the side of the column facing the material bucket, and the locking rod is locked with multiple locking blocks to achieve locking between the upper body and the column, so as to avoid the upper body from shaking and becoming unstable relative to the column when the dough mixer is working, thereby improving the stability of the dough mixer.

[0017] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Please refer to Figures 1-7The dough-making machine of the present invention includes a lower body 100, an upper body 200, a column 300, and a material hopper 400. The column 300 is fixed to the lower body 100, and the material hopper 400 is placed on the lower body 100. The column 300 is located between the upper body 200 and the lower body 100. The upper body 200 is rotatably connected to the column 300. A plurality of locking blocks 310 are detachably fixedly connected to the side of the column 300 facing the material hopper 400. The side of the upper body 200 facing the locking blocks 310 is provided with a through hole 210 for the locking blocks 310 to pass through. A locking rod 500 is rotatably connected to the upper body 200. The locking blocks 310 are provided with locking grooves 31. 1. The locking rod 500 is provided with multiple locking parts 510 that cooperate with the locking groove 311. The locking parts 510 and the locking groove 311 correspond one-to-one. When the upper body 200 is lowered, the locking block 310 passes through the through hole 210. Rotating the locking rod 500 causes the multiple locking parts 510 to be respectively placed into the corresponding locking groove 311, so that the upper body 200 and the column 300 are in a locked state. At this time, the upper body 200 is close to the column 300. Rotating the locking rod 500 causes the locking parts 510 to be disengaged from the locking groove 311, so that the upper body 200 and the column 300 are in a unlocked state. At this time, the upper body 200 can rotate relative to the column 300.

[0020] In an embodiment of the present invention, the column 300 supports the upper body 200, and the lower body 100 is rotatably connected to the base, with the material bucket 400 snapped onto the base. The material bucket 400 can rotate relative to the lower body 100. The upper body 200 is rotatably connected to the column 300, and this connection can be achieved, but is not limited to, through a rotary joint 250. Rotating the upper body 200 causes the dough mixer to tilt upwards.

[0021] A locking rod 500 is rotatably connected to the upper body 200. The locking rod 500 can rotate about its axis relative to the upper body 200. By rotating the locking rod 500, the locking part 510 enters or disengages from the locking groove 311. During the rotation of the locking rod 500 relative to the upper body 200, the locking rod 500 only rotates and does not translate. (Reference) Figure 7 ,by Figure 7 The diagram shown, from left to right, illustrates the locking lever and locking block transitioning from the unlocked to the locked state. As the locking block rotates, the volume of the locking part inserted into the locking groove gradually increases.

[0022] Multiple locking blocks 310 are detachably fixed to the side of the column 300 facing the material tank 400. The upper body 200 has a through hole 210 on the side facing the locking blocks 310 for the locking blocks 310 to pass through. When the dough mixer needs to be used for kneading, the upper body 200 is lowered. At this time, the locking blocks 310 pass through the through hole 210. The through hole 210 prevents movement interference between the upper body 200 and the locking blocks 310. A locking rod 500 is rotatably connected to the upper body 200. The locking rod 500 has a locking part 510, and the locking blocks 310 have locking grooves 311. By rotating the locking rod 500, the locking part 510 can enter or disengage from the locking groove 311. When it is necessary to lock the upper body 200 to the column 300, rotating the locking rod 500 causes the locking part 510 to enter the locking groove 311. The locking block 310 can then hold the locking rod 500 in place, preventing the upper body 200 from rotating relative to the column 300. When it is necessary to unlock the upper body 200 from the column 300, rotating the locking rod 500 causes the locking part 510 to disengage from the locking groove 311. The locking block 310 will not hold the locking rod 500 in place, allowing the upper body 200 to rotate relative to the column 300.

[0023] Multiple locking blocks 310 are detachably fixed to the side of the column 300 facing the material hopper 400. These locking blocks 310 have identical structures and are fixed to the column 300 at the same height. A locking rod 500 can engage with the locking blocks 310. Specifically, a locking part 510 is provided at the position where the locking rod 500 engages with the locking blocks 310, and each locking part 510 corresponds one-to-one with a locking groove 311. By rotating the locking rod 500, the multiple locking parts 510 simultaneously enter or disengage from their corresponding locking grooves 311. When locking the upper body 200 to the column 300, rotating the locking rod 500 causes the multiple locking parts 510 to enter their corresponding locking grooves 311. The multiple locking blocks 310 can then hold the locking rod 500 in place, preventing the upper body 200 from rotating relative to the column 300 and ensuring the stability of the locking mechanism. Compared to the prior art where the locking block 310 is placed near the center of the column 300, this application places the locking block 310 on the side of the column 300 facing the material bucket 400, which increases the distance between the locking block 310 and the rotating joint 250, further improving the stability of the locking between the upper body 200 and the column 300.

[0024] Furthermore, the locking rod 500 is provided with multiple unlocking slots 520, and the locking part 510 corresponds one to one with the unlocking slot 520. The unlocking slot 520, the locking part 510 and the locking slot 311 are all set as semi-cylinders. When the locking rod 500 is rotated so that the unlocking slot 520 is aligned with the locking slot 311, the upper body 200 and the column 300 are in an unlocked state.

[0025] In an embodiment of the invention, rotating the locking rod 500 causes it to rotate only about its axis, so that the unlocking groove 520 or the locking part 510 aligns with the locking groove 311. When the unlocking groove 520 aligns with the locking groove 311, the upper body 200 and the column 300 are in a unlocked state. When the locking part 510 aligns with the locking groove 311, the upper body 200 and the column 300 are in a locked state. When the upper body 200 and the column 300 are in a unlocked state, the locking rod 500 will not stop the locking block 310 due to the unlocking groove 520.

[0026] The locking rod 500 is cylindrical, while the unlocking groove 520 and locking part 510 are semi-cylinders. The radii of the locking rod 500, unlocking groove 520, and locking part 510 are all equal. By partially removing the semi-cylinder from the locking position of the locking rod 500, the unlocking groove 520 and locking part 510 are obtained. The remaining portion is the locking part 510, and the area where the semi-cylinder was removed is the unlocking groove 520.

[0027] Both the locking groove 311 and the locking part 510 are designed as semi-cylinders, allowing for a closer fit between them when locked together, thus improving locking stability. When the locking rod 500 is rotated to lock, the locking part 510 enters the locking groove 311 from its lower portion, while the unlocking groove 520 disengages from the upper portion of the locking groove 311. During locking, simply place the bottom of the locking part 510 into the opening of the locking groove 311, and then rotate the locking rod 500 to allow the locking part 510 to enter the locking groove 311. Precise positioning is not required, reducing operational difficulty. As the locking part 510 enters the locking groove 311, its volume gradually increases, causing the locking rod 500 to be gradually pressed down, pulling the lower body 100 closer to and until it is flush against the column 300.

[0028] Furthermore, the locking rod 500 is located inside the upper body 200, with one end of the locking rod 500 extending out of the upper body 200 and bent to form a handle 530.

[0029] In an embodiment of the present invention, when the upper body 200 and the column 300 are in the locked state, the locking block 310 passes through the through hole 210 into the upper body 200, and the locking groove 311 is located inside the upper body 200, preventing the locking structure formed by the locking rod 500 and the locking groove 311 from being exposed, thus ensuring the safety of the head-up and dough-making machine. One end of the locking rod 500 extends out of the upper body 200 and is bent to form a handle 530. When it is necessary to switch the locking state, the locking rod 500 can be rotated by grasping the handle 530, reducing the difficulty of rotating the locking rod 500.

[0030] Furthermore, the upper body 200 is fixedly connected with a positioning spring plate 220, and the locking rod 500 is provided with a positioning groove 560. The positioning spring plate 220 presses against the locking rod 500. When the axis of the handle 530 and the axis of the locking rod 500 are on the same vertical plane, and the end of the handle 530 away from the locking rod 500 is tilted upward, the positioning spring plate 220 is partially located in the positioning groove 560, and the bottom of the positioning groove 560 is in surface contact with the positioning spring plate 220. The upper body 200 and the column 300 are in a non-locked state. When the axis of the handle 530 and the axis of the locking rod 500 are on the same vertical plane, and the end of the handle 530 away from the locking rod 500 is tilted downward, multiple locking parts 510 are respectively placed into the corresponding locking grooves 311, and the upper body 200 and the column 300 are in a locked state.

[0031] In embodiments of the present invention, the positioning spring plate 220 is fixedly connected to the upper body 200, and may be, but is not limited to, fixedly connected to the upper body 200 by bolts. The positioning spring plate 220, by its own elastic force, keeps the locking rod 500 pressed tightly. The locking rod 500 is provided with a positioning groove 560. When the locking rod 500 is rotated and the positioning spring plate 220 partially enters the positioning groove 560, the rotational resistance of the locking rod 500 increases.

[0032] When the axis of the handle 530 and the axis of the locking rod 500 are in the same vertical plane, and the end of the handle 530 away from the locking rod 500 is tilted upwards, the positioning spring plate 220 is partially located in the positioning groove 560, and the positioning spring plate 220 is in surface contact with the bottom of the positioning groove 560. This increases the rotational resistance of the locking rod 500. When the user releases the handle 530, the locking rod 500 will not rotate, keeping the locking rod 500 and the locking block 310 in an unlocked state. This makes it easier for the user to perceive the unlocked position, and during unlocking, it is not necessary to hold the handle 530 with one hand to maintain the unlocked state of the locking rod 500, reducing the difficulty of operation. Furthermore, with the axis of the handle 530 and the axis of the locking rod 500 in the same vertical plane, and the end of the handle 530 away from the locking rod 500 tilted upwards, the locking rod 500 can provide good support for the handle 530, reducing the possibility that the handle 530 will rotate the locking rod 500 under its own weight.

[0033] When the upper body 200 and the column 300 are in the locked state, multiple locking parts 510 are respectively placed into the corresponding locking grooves 311. The axis of the handle 530 and the axis of the locking rod 500 are located in the same vertical plane, and the end of the handle 530 away from the locking rod 500 is tilted downward. During the operation of the dough mixer, the dough mixer may shake, and the handle 530 may deviate. However, under the action of its own weight, the handle 530 will quickly return to its original position. Of course, if the shaking of the dough mixer exerts a small force on the handle 530, it cannot overcome the weight of the handle 530, and the handle 530 will not deviate. This prevents the locking parts 510 from disengaging from the locking grooves 311, making the locking of the upper body 200 and the column 300 more stable and reliable.

[0034] Furthermore, the upper body 200 includes a first side and a second side arranged opposite to each other. The locking rod 500 is provided with a first step 540 and a second step 550. The first step 540 is located between the second step 550 and the handle 530. The locking rod 500 passes through the first side and the second side. The first step 540 abuts against the side of the first side facing away from the second side, and the second step 550 abuts against the side of the second side facing the first side. A first bolt is screwed to the end of the locking rod 500 away from the handle 530. The nut of the first bolt is located on the side of the second side facing away from the first side.

[0035] In an embodiment of the present invention, the locking rod 500 passes through the first side and the second side, achieving a rotatable connection between the locking rod 500 and the upper body 200, allowing the locking rod 500 to rotate around its axis. The locking rod 500 and the first side are positioned by providing a first step 540 that abuts against the first side. The locking rod 500 and the second side are positioned by providing a second step 550 that abuts against the second side. Positioning the locking rod 500 by having the first step 540 abut against the first side and the second step 550 abut against the second side ensures that when the upper body 200 and the column 300 are locked, the locking block 310 can pass through the unlocking groove 520, preventing interference between the locking rod 500 and the locking block 310.

[0036] The locking rod 500 passes through the first side and the second side, and the locking rod 500 will contact the bottom surface of the upper body 200. When the locking rod 500 and the locking block 310 are locked, the locking rod 500 will press against the first side, the second side and the bottom surface of the upper body 200, further ensuring the stability and reliability of the locking between the upper body 200 and the column 300.

[0037] After the locking rod 500 passes through the first and second sides, the first bolt is screwed onto the locking rod 500 to prevent the locking rod 500 from detaching from the upper body 200. When it is necessary to disassemble the locking rod 500, the first bolt is rotated to disengage it from the locking rod 500, allowing the locking rod 500 to be pulled out from the upper body 200, making disassembly and assembly convenient.

[0038] Furthermore, the included angle between the handle 530 and the locking lever 500 is 110°.

[0039] In embodiments of the present invention, the locking rod 500 is typically horizontally positioned, and the angle between the handle 530 and the locking rod 500 is 110°. This avoids interference between the locking rod 500 and other structures of the head-up dough mixer, and also makes it easier for the user to grip the handle 530.

[0040] Furthermore, it also includes multiple second bolts, which pass through a locking block 310 and are screwed to the column 300. The locking block 310 is provided with a first positioning hole 312, and the column 300 is provided with a second positioning hole. The spring pin is partially inserted into the first positioning hole 312 and partially inserted into the second positioning hole.

[0041] In an embodiment of the present invention, multiple second bolts are used to fix the locking block 310, which facilitates the disassembly and assembly of the locking block 310 and ensures the reliability of the connection between the locking block 310 and the column 300.

[0042] The locking block 310 is provided with a first positioning hole 312, and the column 300 is provided with a second positioning hole. The spring pin is partially inserted into the first positioning hole 312 and partially inserted into the second positioning hole to achieve positioning of the locking block 310 and the column 300.

[0043] Furthermore, the top of the locking block 310 is provided with a chamfer 313.

[0044] In an embodiment of the present invention, the top of the locking block 310 is provided with a chamfer 313, which facilitates the locking block 310 to pass through the through hole 210 when the upper body 200 is lowered.

[0045] Furthermore, two locking blocks 310 are detachably fixedly connected to the side of the column 300 facing the material hopper 400, and the two locking blocks 310 are spaced apart.

[0046] In an embodiment of the present invention, by providing two locking blocks 310, which are respectively locked to the locking rod 500, the upper body 200 and the column 300 are locked together, ensuring locking reliability. At the same time, this reduces production costs.

[0047] Furthermore, when the upper body 200 and the column 300 are in the locked state, the distance between the locking block 310 and the edge of the through hole 210 is 0.2mm.

[0048] In an embodiment of the present invention, when the upper body 200 and the column 300 are in the locked state, the distance between the locking block 310 and the edge of the through hole 210 is 0.2mm. This not only avoids interference between the locking block 310 and the edge of the through hole 210, but also allows the edge of the through hole 210 to be used to limit the movement range of the locking block 310, thereby further improving the stability of the head-up and dough machine.

[0049] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
