Description

Technical Field

[0001] This invention relates to the technical field of food processing equipment, and in particular to a cake-making machine with a dough-stirring function. Background Technology

[0002] In existing cake-making machines, a cup holder is installed below the mixing chamber, with a tray in the middle. When the mixing paddle in the mixing chamber is stirring, the drive structure drives the cup holder to rise, so that the tray is sealed to the mixing chamber. Then the mixing paddle stirs, and the drive structure further drives the cup holder to rise and fall, thereby driving the mixing chamber to rise and fall. This makes the structure of the cup holder and tray relatively complex, and the stirring chamber needs to occupy a lot of space during the raising and lowering process, which is not conducive to the miniaturization of the cake-making machine. Summary of the Invention

[0003] The main objective of this invention is to provide a cake-making machine with a dough-mixing function, which aims to simplify the structure of the tray, reduce the space occupied, and facilitate the miniaturization of the cake-making machine.

[0004] To achieve the above objectives, the present invention proposes a dough-mixing machine, comprising:

[0005] Base;

[0006] A contact chamber, wherein the contact chamber is installed on the machine base;

[0007] The dough mixing assembly includes a dough mixing chamber and a stirring paddle, both mounted on the machine base. The stirring paddle is used to rotate and mix the dough in the dough mixing chamber.

[0008] Screw drive assembly; and

[0009] The pallet and the push block are mounted on the push block. Both the pallet and the push block are connected to the screw drive assembly. The screw drive assembly drives the push block to move along the axial direction of the screw drive assembly, and the screw drive assembly drives the pallet to rise and fall.

[0010] Optionally, the screw drive assembly includes a screw motor and a transmission rod. The screw motor is mounted on the base, and one end of the transmission rod is connected to the output shaft of the screw motor. The push block is rotatably connected to the transmission rod and slidably connected to the receiving chamber. The transmission rod has a lifting groove and a rotating groove. The lifting groove is located at the end of the transmission rod away from the screw motor and extends from the axis of the transmission rod to its outer peripheral surface. The rotating groove is located on the outer peripheral surface of the transmission rod and is spirally arranged. The receiving chamber has a rotating shaft, and the pallet has a lifting shaft extending into the lifting groove. The pallet has a mixing state and a receiving state. In the mixing state, the lifting shaft is located in the lifting groove, and the rotating shaft is disengaged from the rotating groove. In the receiving state, the lifting shaft is disengaged from the lifting groove, and the rotating shaft is located in the rotating groove.

[0011] Optionally, the transmission rod is further provided with a contact groove communicating with the lifting groove. The contact groove is coaxially arranged with the transmission rod, and the diameter of the contact groove is smaller than the diameter of the transmission rod. In the mixing state, the lifting shaft is located in the lifting groove, and the screw motor drives the pallet to move up and down. In the contact state, the lifting shaft is located in the contact groove, and the screw motor drives the pallet to move along the axial direction of the transmission rod.

[0012] Optionally, the lifting groove includes a first lifting groove and a second lifting groove. The first lifting groove is connected to the contact groove, and the second lifting groove is connected to the end of the first lifting groove away from the contact groove. The first lifting groove extends from the axis of the transmission rod to the outer peripheral surface and is arranged in an arc shape. The second lifting groove is coaxially arranged with the contact groove. When the lifting shaft is located in the second lifting groove, the height of the pallet remains unchanged.

[0013] Optionally, the outer circumferential surface of the transmission rod is provided with a first annular groove, the first annular groove extending circumferentially along the transmission rod, and the receiving chamber is provided with a guide shaft. In the mixing state, the lifting shaft is located in the lifting groove, the guide shaft is located in the first annular groove, and the screw motor drives the pallet to lift.

[0014] Optionally, the outer circumferential surface of the transmission rod is provided with a second annular groove, which extends circumferentially along the transmission rod. The contact chamber is provided with a guide shaft, which is located in the second annular groove when the push block moves to a predetermined position.

[0015] Optionally, the pallet is provided with a first guide portion, and the push block is provided with a second guide portion, and the pallet is raised and lowered by the cooperation of the first guide portion and the second guide portion.

[0016] Optionally, the first guide portion is a guide groove, and the second guide portion is a guide protrusion, wherein the guide protrusion is confined within the guide groove.

[0019] The dough-making machine with a dough-mixing function in the technical solution of the present invention includes a base, a dough receiving chamber, a dough mixing assembly, a screw drive assembly, a tray, and a pusher block. The dough receiving chamber is installed on the base. The dough mixing assembly includes a dough mixing chamber and a stirring paddle, both installed on the base. The stirring paddle is used to rotate and mix the dough in the dough mixing chamber. The tray is installed on the pusher block. Both the tray and the pusher block are connected to the screw drive assembly for transmission. The screw drive assembly drives the pusher block to move along the axial direction of the screw drive assembly and drives the tray to rise and fall. The tray has a mixing state and a receiving state. In the mixing state, the tray is located in the mixing chamber, and the screw drive assembly drives the tray to move up and down within the mixing chamber to achieve the effect of mixing and kneading the dough. The push block remains stationary at this time. In the receiving state, the screw drive assembly drives the push block to move along the axis of the screw drive assembly so that the dough in the mixing chamber falls into the receiving chamber. At this time, the tray also moves along the axis of the screw drive assembly under the drive of the push block, but the tray does not move up or down. Compared with the existing technology that drives the entire cup tray and mixing chamber to move up and down, the screw drive assembly of this invention only needs to drive the tray to move up and down, and the tray is located within the mixing chamber during the raising and lowering process. This simplifies the structure of the tray and the cake maker, thereby reducing the production cost of the cake maker. It also reduces the space required during the mixing process, which is conducive to the miniaturization of the cake maker. Attached Figure Description

[0037] Reference Figures 1 to 3 This invention proposes a cake-making machine with a dough-mixing function, comprising:

[0038] Base 10;

[0039] A contact chamber 20 is mounted on the base 10;

[0040] The dough mixing assembly includes a dough mixing chamber 31 and a stirring paddle 32 both mounted on the base 10. The stirring paddle 32 is used to rotate and mix the dough in the dough mixing chamber 31.

[0041] Screw drive assembly; and

[0042] The pallet 52 and the push block 51 are mounted on the push block 51. Both the pallet 52 and the push block 51 are connected to the screw drive assembly. The screw drive assembly drives the push block 51 to move along the axial direction of the screw drive assembly, and the screw drive assembly drives the pallet 52 to rise and fall.

[0043] The dough-making machine with a dough-mixing function in the technical solution of the present invention includes a base 10, a dough receiving chamber 20, a dough mixing assembly, a screw drive assembly, a tray 52, and a pusher block 51. The dough receiving chamber 20 is installed on the base 10. The dough mixing assembly includes a dough mixing chamber 31 and a stirring paddle 32, both installed on the base 10. The stirring paddle 32 is used to rotate and mix the dough in the dough mixing chamber 31. The tray 52 is installed on the pusher block 51. Both the tray 52 and the pusher block 51 are connected to the screw drive assembly for transmission. The screw drive assembly drives the pusher block 51 to move along the axial direction of the screw drive assembly and drives the tray 52 to rise and fall. The tray 52 has a mixing state and a receiving state. In the mixing state, the tray 52 is located in the mixing chamber, and the screw drive assembly drives the tray 52 to rise and fall within the mixing chamber to achieve the effect of mixing and kneading dough. The push block 51 remains stationary at this time. In the receiving state, the screw drive assembly drives the push block 51 to move along the axis of the screw drive assembly so that the dough in the mixing chamber falls into the receiving chamber 20. At this time, the tray 52 also moves along the axis of the screw drive assembly under the drive of the push block 51, but the tray 52 does not rise or fall at this time. Compared with the prior art technology that drives the entire cup tray and mixing chamber to rise and fall, the screw drive assembly of the present invention only needs to drive the tray 52 to rise and fall, and the tray 52 is located within the mixing chamber during the rising and falling process. This simplifies the structure of the tray 52 and the cake maker, thereby reducing the production and manufacturing cost of the cake maker. It also reduces the space required during the mixing process, which is conducive to the miniaturization of the cake maker.

[0044] Reference Figures 2 to 8 Preferably, the screw drive assembly includes a screw motor and a transmission rod 40. The screw motor is mounted on the base 10, and one end of the transmission rod 40 is connected to the output shaft of the screw motor. The push block 51 is rotatably connected to the transmission rod 40 and slidably connected to the contact chamber 20. The transmission rod 40 is provided with a lifting groove and a rotating groove 41. The lifting groove is located at the end of the transmission rod 40 away from the screw motor and extends from the axial direction of the transmission rod 40 to its outer peripheral surface. The rotating groove 41 is provided on the outer peripheral surface of the transmission rod 40 and is spirally arranged. The receiving chamber 20 is provided with a rotating shaft 21, and the pallet 52 is provided with a lifting shaft 521. The lifting shaft 521 extends into the lifting groove. The pallet 52 has a mixing state and a receiving state. In the mixing state, the lifting shaft 521 is located in the lifting groove, and the rotating shaft 21 is disengaged from the rotating groove 41. In the receiving state, the lifting shaft 521 is disengaged from the lifting groove, and the rotating shaft 21 is located in the rotating groove 41.

[0045] In this embodiment, the lifting groove is arc-shaped. Since the transmission rod 40 drives the lifting shaft 521 to slide within the lifting groove during rotation, the running trajectory of the lifting shaft 521 is arc-shaped. Therefore, setting the lifting shaft 521 to an arc shape makes its movement during lifting and lowering more stable and smooth. If the lifting groove were straight, the lifting shaft 521 would experience greater resistance during lifting and lowering, leading to poor operation of the pallet 52 and the lifting shaft 521.

[0046] Furthermore, when the tray 52 switches from the mixing state to the receiving state, the tray 52 moves to the opening of the mixing chamber 31 under the drive of the screw motor, and the tray 52 is flush with the lower end surface of the mixing chamber 31. At this time, the upper end surface of the push block 51 and the tray 52 is flush with the lower end surface of the mixing chamber 31. Then, the screw motor drives the push block 51 to move along the axis of the transmission rod 40. At this time, the push block 51 was originally located in the receiving chamber 20. After the screw motor drives the push block 51 to move, the receiving chamber 20 is at least partially empty. Then, when the push block 51 is no longer in contact with the mixing chamber 31, the dough falls completely into the receiving chamber 20 through the opening at the lower end of the mixing chamber.

[0047] The technical solution of the present invention achieves the horizontal movement of the push block 51 and the lifting and lowering of the pallet 52 using only a screw motor and a transmission rod 40, thus realizing two modes of movement simultaneously. Compared with the prior art, which uses two different motion structures to drive the pallet 52 and the push block 51 to lift and move horizontally, the technical solution of the present invention greatly reduces the number of parts used, thereby reducing the space occupied by the drive structure and thus reducing the production and manufacturing cost of the cake maker.

[0048] Furthermore, one of the push block 51 and the dough receiving chamber 20 is provided with a slide rail 22, and the other is provided with a slide groove 513. The push block 51 is slidably connected to the dough receiving chamber 20 through the cooperation of the slide rail 22 and the slide groove 513. The sliding method of the slide rail 22 and the slide groove 513 is stable and reliable, and the structure is simple and easy to install, thereby reducing the production and manufacturing cost of the cake making machine.

[0049] Furthermore, the transmission rod 40 is also provided with a contact groove 43 communicating with the lifting groove. The contact groove 43 is coaxially arranged with the transmission rod 40, and the diameter of the contact groove 43 is smaller than the diameter of the transmission rod 40. In the mixing state, the lifting shaft 521 is located in the lifting groove, and the screw motor drives the pallet 52 to rise and fall. In the contact state, the lifting shaft 521 is located in the contact groove 43, and the rotating shaft 21 is located in the rotating groove 41. The screw motor drives the pallet 52 to move along the axial direction of the transmission rod 40. By providing a contact groove 43 communicating with the lifting groove, the lifting shaft 521 is located in the contact groove 43 or the lifting groove in both the mixing state and the contact state, thereby reducing the possibility of the lifting shaft 521 deviating from the predetermined track during operation and increasing the stability of the pallet 52's operation.

[0050] When the lifting shaft 521 is located in the contact groove 43, the shortest distance between the lifting shaft 521 and the axis of the transmission rod 40 remains unchanged, so the height of the pallet 52 remains unchanged. At this time, the rotating shaft 21 is located in the rotating groove 41, so the screw motor will only drive the push block 51 to move along the axis of the transmission rod 40, and will not drive the pallet 52 to rise or fall.

[0051] Specifically, the lifting groove includes a first lifting groove 421 and a second lifting groove 422. The first lifting groove 421 is connected to the contact groove 43, and the second lifting groove 422 is connected to the end of the first lifting groove 421 away from the contact groove 43. The first lifting groove 421 extends from the axis of the transmission rod 40 to the outer peripheral surface and is arc-shaped. The second lifting groove 422 is coaxially arranged with the contact groove 43. When the lifting shaft 521 is located in the second lifting groove 422, the height of the pallet 52 remains unchanged. When the lifting shaft 521 is located in the first lifting groove 421, the pallet 52 will move up and down. When the lifting shaft 521 is located in the second lifting groove 422, the height of the pallet 52 will remain unchanged. Understandably, when the screw motor drives the pallet 52 to lift and lower, the screw motor's precision cannot be set too precisely. That is, it is difficult to make the screw motor stop and reverse immediately after the pallet 52 is raised to the highest point. Therefore, by setting the second lifting groove 422, a certain buffer and error are given to the lifting shaft 521, thereby reducing the precision of the screw motor and thus reducing the cost of the screw motor.

[0052] Furthermore, the outer circumferential surface of the transmission rod 40 is provided with a first annular groove 44, which extends circumferentially along the transmission rod 40 and communicates with the rotating groove 41. The dough receiving chamber 20 is provided with a rotating shaft 21. In the dough stirring state, the lifting shaft 521 is located in the lifting groove, and the rotating shaft 21 is located in the first annular groove 44. The screw motor drives the pallet 52 to move up and down. When the rotating shaft 21 is located in the first annular groove 44, it is equivalent to the rotating shaft 21 only rotating idly in the first annular groove 44, so it will not drive the push block 51 to move. At this time, the lifting shaft 521 has already rotated into the lifting groove, so the screw motor will only drive the pallet 52 to move up and down, and will not drive the push block 51 to move. By setting the first annular groove 44, the rotation direction of the rotating shaft 21 is limited, thereby improving the stability of the movement of the push block 51 and the pallet 52.

[0053] The outer circumferential surface of the transmission rod 40 is provided with a second annular groove 45. The second annular groove 45 extends along the circumference of the transmission rod 40 and is connected to the rotating groove 41. The dough receiving chamber 20 is provided with a rotating shaft 21. When the push block 51 drives the tray 52 to move to a position opposite to the mixing chamber 31, the rotating shaft 21 is located in the second annular groove 45.

[0054] Understandably, when the screw motor drives the pusher block 51 to move, it is difficult to stop it at a precise position. To achieve this, more sensors and a more precise motor would be required, which would increase the manufacturing and maintenance costs of the biscuit machine. Since the dough receiving chamber 20 and the pusher block 51 are slidably connected by the slide rail 22 and the slide groove 513, in order to prevent the pusher block 51 from moving excessively and causing the slide rail 22 and the slide groove 513 to disengage, the technical solution of the present invention provides a second annular groove 45. When the rotating shaft 21 is located in the second annular groove 45, the pusher block 51 does not move, thereby preventing the pusher block 51 from disengaging from the slide rail 22 and the slide groove 513 on the dough receiving chamber 20.

[0055] Reference Figure 2 , Figure 3 as well as Figure 9 In this embodiment, the pallet 52 is provided with a first guide portion, and the push block 51 is provided with a second guide portion. The pallet 52 is raised and lowered through the cooperation of the first guide portion and the second guide portion. By setting the first guide portion and the second guide portion, the stability of the pallet 52 during the raising and lowering process is further increased, preventing the pallet 52 from deviating from the predetermined passage. At the same time, during the process of switching from the dough contact state to the dough mixing state, the pallet 52 must move precisely to the opening at the lower end of the dough mixing chamber 31 so that it can be accurately inserted into the dough mixing chamber 31. Therefore, by setting the first guide portion and the second guide portion, the operation of the pallet 52 is made more precise and stable.

[0056] Specifically, the first guide portion is a guide groove 522, and the second guide portion is a guide protrusion 511, with the guide protrusion 511 confined within the guide groove 522. By providing the guide protrusion 511 and the guide groove 522, the pallet 52 can be raised and lowered in a predetermined direction, allowing the pallet 52 to accurately extend into the mixing chamber 31. Simultaneously, the guide protrusion 511 and the guide groove 522 have simple structures and are easy to manufacture, thereby reducing the production cost of the cake-making machine. Of course, in other embodiments, the first guide portion and the second guide portion can be a first guide rod and a second guide rod, respectively, wherein the second guide rod is hollow, and the first guide rod is inserted into the hollow second guide rod, thereby enabling the pallet 52 to rise and fall in a predetermined direction.

[0057] In this embodiment, the tray 52 is provided with a first limiting part, and the push block 51 is provided with a second limiting part. The lifting height of the tray 52 is controlled by the first limiting part and the second limiting part. Understandably, when the tray 52 is lowered to its lowest point, the tray 52 is flush with the push block 51. If the tray 52 continues to descend, firstly, the tray 52 will interfere with and collide with the push block 51, potentially damaging the equipment. Secondly, dough may easily get stuck between the tray 52 and the push block 51, making it difficult for the user to clean. If the tray 52 rises too high, it will interfere with and collide with the mixing paddle 32, potentially damaging the mixing paddle 32 and / or the tray 52. ​​Therefore, by setting the first limiting part and the second limiting part, the maximum lifting height and minimum lowering height of the tray 52 are limited, thereby improving the stability of the biscuit maker, reducing the occurrence of accidents, and improving the safety and reliability of the equipment.

[0058] Specifically, the first limiting part is a first limiting protrusion 512 provided on the guide protrusion 511, and the second limiting part is a second limiting protrusion 523 provided in the guide groove 522. The first and second limiting parts limit the maximum rising height of the tray 52, thereby reducing the possibility of collision interference between the tray 52 and the stirring paddle 32, and thus reducing the possibility of damage to the stirring paddle 32 and / or the tray 52. ​​Furthermore, the push block 51 is provided with a third limiting protrusion. When the tray 52 descends to its lowest height, the lower end face of the tray 52 abuts against the third limiting protrusion, thereby reducing the gap between the dough and the push block 51, thus reducing the amount of cleaning required for the biscuit maker, and thus improving the user experience.

[0059] Furthermore, the tray 52, or at least its outer periphery, is flexible. This ensures that when the screw motor drives the tray 52 into the mixing chamber 31, the tray 52 and the mixing chamber 31 are sealed together, preventing flour, water, oil, etc., from leaking out through the gap between the tray 52 and the mixing chamber 31. Firstly, a proper ratio of water, oil, and flour is added to the dough before production to ensure a better taste and texture in the final product. Therefore, loss of water, oil, and flour would cause the final dough to fail to meet predetermined standards, affecting the taste of the pancake. Secondly, loss of water, oil, and flour would also require the pancake maker to be cleaned regularly, increasing the cleaning workload for the user and reducing the user experience.

[0060] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
