Description

Technical Field

[0001] The present invention relates to the technical field of tilting dough mixers, and in particular to a stirring device and a stirring method for a tilting dough mixer. Background Art

[0002] A tilting dough mixer is a common type of dough mixer, usually used in the pasta production and processing industry. Its main function is to mix flour with water and other ingredients and knead them into a uniform dough. This type of dough mixer is common in medium and large-sized catering industries and food processing plants because it can efficiently produce a large amount of dough and improve production efficiency.

[0003] The existing baffle guardrail on a tilting dough mixer generally uses a one-piece design, and after the dough mixing is completed, it is necessary to manually flip the guardrail up or operate the machine to rotate and flip it. However, both methods will occupy the space of the equipment and hinder the material taking.

[0004] At the same time, due to the humidity after the flour and water are mixed, the phenomenon of adhesion between the flour and the inner wall of the dough mixing tank often occurs during the dough mixing process. This adhesion not only causes material waste but also increases the cleaning workload, extending the maintenance cycle of the equipment. When the cleaning is not thorough, it may affect the quality of the dough produced next time, causing cross-contamination or uneven mixing. Therefore, there are many difficulties in the cleaning process of the existing tilting dough mixer. Especially when the dough remains on the inner wall or corners of the dough mixing tank, manual cleaning is not only time-consuming and laborious but also prone to missing details, resulting in unnecessary hygiene problems during the next production. As the usage frequency of the equipment increases, the cleaning workload increases significantly, affecting the operating efficiency of the equipment. Therefore, the present invention is proposed to solve the deficiencies of the above technical problems. Summary of the Invention

[0005] Based on the above existing technical problems, the present invention proposes a stirring device and a stirring method for a tilting dough mixer.

[0006] A stirring device for a tilting dough mixer proposed by the present invention includes a numerical control table. A rotating shaft is rotatably connected to the surface of the numerical control table. A turning plate is fixedly connected to the outer surface of the middle part of the rotating shaft. A numerical control beam is fixedly connected to one side surface of the turning plate. The lower surface of the numerical control beam is in sliding contact with the upper surface of the bottom plate of the numerical control table through a support leg. A buffer telescopic rod is fixedly connected to the upper surface of the bottom beam of the numerical control beam. A dough mixing tank is rotatably connected to the upper surface of the buffer telescopic rod through a turntable. A protection mechanism is arranged on the upper surface of the dough mixing tank. A main shaft is rotatably connected to the lower surface of the top beam of the numerical control beam. A stirring and scraping mechanism is arranged on the outer surface of the main shaft. An adjusting mechanism is arranged on one side of the middle beam of the numerical control beam.

[0007] Among them, the protection mechanism automatically rotates and opens on the upper surface of the dough mixing tank, that is, it closes the upper surface of the dough mixing tank during dough mixing, and makes the upper surface of the dough mixing tank open when turning over and pouring out the dough, so as to facilitate the taking out of the dough.

[0008] Among them, the stirring and scraping mechanism rotates with the main shaft, not only stirring and kneading the dough, but also scraping the materials adhered to the inner wall of the dough mixing tank.

[0009] Among them, the adjusting mechanism controls the relative rotation of the dough mixing tank and the main shaft, and reciprocally adjusts the height of the dough mixing tank when the stirring and scraping mechanism processes the dough.

[0010] Preferably, the protection mechanism includes a material blocking guardrail annularly distributed on the upper surface of the dough mixing tank. The inner surfaces and outer surfaces of two adjacent material blocking guardrails are in sliding contact. The outer surface of the main shaft is slidably clamped with a rotating bearing through the cooperation of a key and a keyway. The outer surface of the outer ring of the rotating bearing is fixedly sleeved with a support ring. The outer surface of the support ring is provided with a sliding card slot. The inner wall of the sliding card slot is annularly distributed and slidably clamped with a support rod with a roller.

[0011] Through the above technical solution, the material blocking guardrail on a general dough mixing tank is of a one-piece type, and after dough mixing, it is necessary to manually turn up the guardrail or operate the machine to rotate and turn it over, but both will occupy the space of the equipment and hinder the taking of materials. In order to realize the automatic adjustment of the material blocking guardrail to facilitate its opening or closing, the multi-piece type material blocking guardrail is controlled to rotate on the upper surface of the dough mixing tank. When it is opened, it forms an annular material blocking guardrail to complete the protection function. When it contracts, multiple material blocking guardrails are stacked layer by layer, so that multiple material blocking guardrails contract to one side, thereby realizing the exposure above the dough mixing tank and making it easy to take out the dough. In order to support the rotating material blocking guardrail, the material blocking guardrail is connected to the support ring on the main shaft through a support rod, so that the material blocking guardrail rotates around the main shaft to complete its rotation, contraction or expansion action.

[0012] Preferably, the protection mechanism further includes an annular card slot opened on the upper surface of the dough mixing tank. The inner wall of the annular card slot is annularly and arrayedly distributed and slidably clamped with a group of two linked blocks. The upper surface of each group of linked blocks is hinged with a V-shaped hinged link. Adjacent hinged links are hinged to each other. The upper surface of one of the linked blocks in each group is fixedly connected to the inner surface of the material blocking guardrail through a connecting piece.

[0013] Through the above technical solution, in order to drive the material retaining guardrail to unfold and stack and contract, the V-shaped articulated link in each group is opened, so as to drive the material retaining guardrail connected to its upper surface to rotate and open. At this time, the support rod rotates in the sliding card slot of the support ring. When the included angle of the V-shaped articulated link becomes smaller, it contracts, so that it drives the material retaining guardrail to contract. The multiple articulated links are hinged to each other, and the linkage of multiple material retaining guardrails can be realized.

[0014] Preferably, the protection mechanism further includes a fixed block fixedly connected to the inner surface of the annular card slot. A servo motor is fixedly connected to the outer surface of the dough mixing tank. The outer surface of the output shaft of the servo motor passes through the fixed block and is fixedly connected to a driving rod. The free end of the driving rod is hinged to the upper surface of the first linkage block in the first group.

[0015] Through the above technical solution, in order to drive multiple groups of articulated links to unfold or contract, the servo motor controls the driving rod to rotate, so that the free end of the driving rod pushes the first group of articulated links to unfold or contract, and further makes the linkage block rotate in the annular card slot, so that the material retaining guardrail completes rotation. And because the multiple articulated links are connected to each other, the linkage can be realized.

[0016] Preferably, the stirring and scraping mechanism includes a cross fixed to the lower surface of the main shaft. Scraping plates are fixedly connected to the lower surfaces of the opposite two struts of the cross, and the outer surface of the scraping plate is slidably connected to the inner wall of the dough mixing tank.

[0017] Through the above technical solution, when the dough mixer is kneading dough, due to the humidity of the flour, there will be flour sticking to the inner wall of the dough mixing tank in the early stage, which will cause waste and increase the cleaning process at the same time. In order to improve the dough kneading effect, the surface of the scraping plate in contact with the inner wall of the dough mixing tank is made of rubber material. When it rotates, it can peel off the stuck flour blocks and then stir and knead them with the dough, thereby improving the dough kneading efficiency at the same time.

[0018] Preferably, the stirring and scraping mechanism further includes stirring rods rotatably connected to the surfaces of the other opposite two struts of the cross through bearings. A fixed gear is rotatably sleeved on the outer surface of the main shaft. A driven gear is fixedly sleeved on the upper outer surface of the stirring rod, and the driven gear meshes with the fixed gear.

[0019] Through the above technical solution, in order to improve the stirring effect of the dough, while the two stirring rods revolve to stir the dough, they rotate around the meshing fixed gear through the driven gear, so that the stirring rods can be driven to rotate, and the revolving stirring rods keep rotating, so as to accelerate the stirring of the dough and make it take shape.

[0020] Preferably, the adjusting mechanism includes a toothed ring fixedly sleeved on the outer surface of the dough mixing tank. A support ring plate is rotatably sleeved on the outer surface of the dough mixing tank. A reduction motor is fixedly connected to the lower surface of the ear plate of the support ring plate. A driving gear is fixedly connected to the outer surface of the output shaft of the reduction motor. The driving gear meshes with the toothed ring.

[0021] Through the above technical solution, in order to improve the scraping effect of the scraping plate and the dough mixing effect, when the stirring and scraping mechanism is working, the reduction motor is used to control the driving gear to rotate. Then, the engaged toothed ring drives the dough mixing tank to rotate on the surface of the support ring plate, so that the dough mixing tank and the scraping plate rotate relative to each other, increasing the scraping effect of the scraping plate and at the same time being able to control the rotation of the dough to improve the mixing effect.

[0022] Preferably, the adjusting mechanism further includes a movable groove opened on one side surface of the middle beam of the numerical control beam. An adjusting screw is rotatably connected to the inner wall of the movable groove through a bearing. One end of the support ring plate is threadedly sleeved on the outer surface of the adjusting screw, and its outer surface is slidably connected to the inner wall of the movable groove.

[0023] Through the above technical solution, in order to fully stir the dough at the bottom of the dough mixing tank, after the numerical control beam controls the rotation of the adjusting screw, the height of the support ring plate can be adjusted, so as to control the height adjustment of the dough mixing tank. And the dough mixing tank is supported by the buffer telescopic rod to achieve weight bearing, thereby improving the stability of its height adjustment.

[0024] Preferably, a rotary encoder is installed on the outer surface of one end of the rotating shaft.

[0025] Through the above technical solution, after the numerical control table controls the rotation of the rotating shaft, the turnover plate can drive the turnover of the dough mixing tank, so as to realize the pouring action. In order to accurately control the rotation angle of the rotating shaft, a rotary encoder is set at one end of it, so that it outputs corresponding electrical signals according to the rotation angle or position, which is used to measure the rotation angle of the rotating shaft.

[0026] A stirring method for a stirring device of a tilting vat dough mixer proposed by the present invention includes the following steps:

[0027] S1. When the tilting vat dough mixer is mixing dough, raw materials are put into the dough mixing tank, and then the servo motor is controlled to start, so that it controls the driving rod to rotate, so that the free end of the driving rod pushes the first group of articulated linkages to unfold. Since multiple articulated linkages are connected to each other, linkage is realized;

[0028] S2. The V-shaped articulated linkages in each group are opened on the upper surface of the dough mixing tank, so that the linkage blocks rotate in the annular card slots, so that the material blocking guardrails complete rotation. At this time, the support rods rotate in the sliding card slots of the support rings, and then the superimposed material blocking guardrails unfold to form an annular material blocking guardrail to complete the protection function;

[0029] S3. After the material baffle guardrail is closed, the numerical control beam controls the main shaft to rotate, which drives the cross to rotate. Then, while the two stirring rods revolve to stir the dough, they rotate around the meshing fixed gear through the driven gear, so as to drive the stirring rods to rotate, enabling the revolving stirring rods to maintain rotation, thereby accelerating the stirring of the dough to make it take shape.

[0030] S4. While the stirring rods are stirring the flour, the scraping plate on the lower surface of the cross revolves, making its rubber surface contact with the inner wall of the dough mixing tank, so as to flake off the adhered flour lumps, and then making them stir and knead with the dough, thereby improving the kneading efficiency at the same time.

[0031] S5. While the stirring and scraping mechanism is working, the reduction motor controls the driving gear to rotate, and the meshing gear ring drives the dough mixing tank to rotate on the surface of the supporting ring plate, so that the dough mixing tank and the scraping plate rotate relative to each other, increasing the scraping effect of the scraping plate, and at the same time being able to control the rotation of the dough to improve the stirring effect.

[0032] S6. While kneading the dough, the numerical control beam controls the adjusting screw to rotate, so as to adjust the height of the supporting ring plate, thereby controlling the dough mixing tank to achieve height adjustment, and further realizing the full stirring of the dough.

[0033] S7. After the dough is stirred, the servo motor controls the driving rod to act in the reverse direction. When the angle between the V-shaped articulated link becomes smaller, it contracts, driving the material baffle guardrail to contract to one side, so as to expose the upper part of the dough mixing tank, making it easy to take out the dough. When taking out the dough, the rotary encoder outputs corresponding electrical signals according to the rotation angle or position, which is used to measure the rotation angle of the rotating shaft. After the numerical control table controls the rotating shaft to rotate, the flip plate can drive the dough mixing tank to flip, so as to achieve the discharging action.

[0034] The beneficial effects of the present invention are as follows:

[0035] 1. By setting the protection mechanism, the upper surface of the dough mixing tank can be automatically rotated and opened and closed, thereby reducing the occupied area during its operation. During the adjustment process, by controlling the multi-piece material baffle guardrail to rotate on the upper surface of the dough mixing tank, when it is opened, it forms an annular material baffle guardrail to complete the protection function. When it contracts, multiple material baffle guardrails are stacked layer by layer, and the multiple material baffle guardrails contract to one side, so as to expose the upper part of the dough mixing tank, making it easy to take out the dough, and reducing the potential safety hazard caused by the need to flip up the material baffle guardrail. In terms of food, it ensures the safety protection of the dough during the kneading process, avoids external pollution, improves the operation convenience, ensures the safety of the operator, and reduces unnecessary interference.

[0036] 2. By setting up a stirring and scraping mechanism, it not only stirs and kneads the dough, but also scrapes the materials adhered to the inner wall of the kneading tank. During the adjustment process, while the stirring rod stirs the flour, the scraping plate on the lower surface of the cross forms a revolution, making its rubber surface contact with the inner wall of the kneading tank, thereby peeling off the adhered flour lumps, and then making them be stirred and kneaded with the dough. Furthermore, it improves the kneading efficiency and reduces the process of cleaning the inner wall of the kneading tank later. That is, in terms of equipment and cleaning, it reduces the accumulation of flour residues, avoids the long-term accumulation of difficult-to-clean flour lumps inside the equipment, and the automatic scraping design reduces the manual cleaning time, improves the cleaning efficiency, and at the same time improves the hygiene standard of the equipment, reducing the risk of bacterial growth caused by the adhered materials.

[0037] 3. By setting up an adjustment mechanism, it controls the relative rotation of the kneading tank and the main shaft, and reciprocally adjusts the height of the kneading tank when the stirring and scraping mechanism processes the dough. During the adjustment process, the numerical control beam controls the rotation of the adjustment screw rod to adjust the height of the support ring plate, thereby controlling the height adjustment of the kneading tank, and then realizing the full stirring of the dough. And through the meshing gear rings, it drives the kneading tank to rotate on the surface of the support ring plate, so that the kneading tank and the scraping plate rotate relatively, increasing the scraping effect of the scraping plate, and at the same time being able to control the rotation of the dough to improve the stirring effect. The full stirring of the dough ensures the uniformity and quality of the dough, improving the taste and quality of the food. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0050] Refer to Figures 1-10 , a stirring device of a cylinder-turning dough mixer, including a numerical control table 1, a rotating shaft 11 is rotatably connected to the surface of the numerical control table 1, a turning plate 12 is fixedly connected to the outer surface of the middle part of the rotating shaft 11, a numerical control beam 2 is fixedly connected to one side surface of the turning plate 12, the lower surface of the numerical control beam 2 is in sliding contact with the upper surface of the bottom plate of the numerical control table 1 through a support leg, a buffer telescopic rod 21 is fixedly connected to the upper surface of the bottom beam of the numerical control beam 2, the upper surface of the buffer telescopic rod 21 is rotatably connected to a dough mixing tank 3 through a turntable, a protection mechanism 4 is arranged on the upper surface of the dough mixing tank 3, a main shaft 22 is rotatably connected to the lower surface of the top beam of the numerical control beam 2, a stirring and scraping mechanism 6 is arranged on the outer surface of the main shaft 22, and an adjusting mechanism 7 is arranged on one side of the middle beam of the numerical control beam 2.

[0051] After the numerical control table 1 controls the rotation of the rotating shaft, the turning plate 12 can drive the turning of the dough mixing tank 3, so as to realize the discharging action. In order to accurately control the rotation angle of the rotating shaft 11, a rotary encoder 13 is installed on the outer surface of one end of the rotating shaft 11. The rotary encoder 13 is arranged at one end of the rotating shaft 11, so that it outputs corresponding electrical signals according to the rotation angle or position, and is used to measure the rotation angle of the rotating shaft 11.

[0052] Among them, the protection mechanism 4 automatically rotates and opens and closes on the upper surface of the dough mixing tank 3, that is, it closes the upper surface of the dough mixing tank 3 during dough mixing, and makes the upper surface of the dough mixing tank 3 open during turning and discharging, so as to facilitate the taking out of the dough.

[0053] Generally, the material retaining guardrail 41 on the dough mixing tank 3 is in one piece, and after the dough mixing is completed, it is necessary to manually turn up the guardrail or operate the machine to rotate and turn it, but both will occupy the space of the equipment and prevent the taking out of the material. In order to realize the automatic adjustment of the material retaining guardrail 41 so that it is easy to open or close, the protection mechanism 4 includes a material retaining guardrail 41 arranged in a ring distribution on the upper surface of the dough mixing tank 3. The inner surface and the outer surface of two adjacent material retaining guardrails 41 are in sliding contact. The outer surface of the main shaft 22 is slidably clamped with a rotating bearing 42 through the cooperation of a key and a keyway, and controls the multi-piece material retaining guardrail 41 to rotate on the upper surface of the dough mixing tank 3. When it is opened, a ring-shaped material retaining guardrail 41 is formed to complete the protection function. When it contracts, multiple material retaining guardrails 41 are stacked layer by layer, so that multiple material retaining guardrails 41 contract to one side, so as to expose the upper part of the dough mixing tank 3, making it easy to take out the dough. In order to support the rotating material retaining guardrail 41, a support ring 43 is fixedly sleeved on the outer surface of the outer ring of the rotating bearing 42. A sliding card slot 44 is opened on the outer surface of the support ring 43, and a support rod 45 with a roller is slidably clamped on the inner wall of the sliding card slot 44 in a ring distribution. The material retaining guardrail 41 is connected to the support ring 43 on the main shaft 22 through the support rod 45, so that the material retaining guardrail 41 rotates around the main shaft 22 to complete its rotation, contraction or expansion action.

[0054] In order to drive the material baffle guardrail 41 to expand and stack and contract, the protection mechanism 4 further includes an annular card slot 46 opened on the upper surface of the dough mixing tank 3. The inner wall of the annular card slot 46 is slidably clamped with linkage blocks 47 in an annular array in pairs. The upper surface of each group of linkage blocks 47 is hinged with a V-shaped hinged connecting rod 48. The adjacent hinged connecting rods 48 are hinged to each other. The upper surface of one of the linkage blocks 47 in each group is fixedly connected to the inner surface of the material baffle guardrail 41 through a connecting member. By opening each group of V-shaped hinged connecting rods 48, the material baffle guardrail 41 connected to its upper surface is pushed to rotate and open. At this time, the support rod 45 rotates in the sliding card slot 44 of the support ring 43. When the included angle of the V-shaped hinged connecting rod 48 becomes smaller, it contracts, driving the material baffle guardrail 41 to contract. Since the multiple hinged connecting rods 48 are hinged to each other, the linkage of multiple material baffle guardrails 41 can be realized.

[0055] In order to drive multiple groups of hinged connecting rods 48 to expand or contract, the protection mechanism 4 further includes a fixed block 49 fixedly connected to the inner surface of the annular card slot 46. The outer surface of the dough mixing tank 3 is fixedly connected with a servo motor 50. The outer surface of the output shaft of the servo motor 50 passes through the fixed block 49 and is fixedly connected with a driving rod 51. The free end of the driving rod 51 is hinged to the upper surface of the first linkage block 47 in the first group. The servo motor 50 controls the driving rod 51 to rotate, so that the free end of the driving rod 51 pushes the first group of hinged connecting rods 48 to expand or contract, and then the linkage blocks 47 rotate in the annular card slot 46, so that the material baffle guardrail 41 completes rotation. And because the multiple hinged connecting rods 48 are connected to each other, the linkage can be realized.

[0056] By setting the protection mechanism 4, the upper surface of the dough mixing tank 3 can be automatically rotated and opened and closed, thereby reducing the occupied area during its operation. During the adjustment process, by controlling the multi-piece material baffle guardrail 41 to rotate on the upper surface of the dough mixing tank 3, when it is opened, a circular material baffle guardrail 41 is formed to complete the protection function. When it contracts, multiple material baffle guardrails 41 are stacked layer by layer, so that multiple material baffle guardrails 41 contract to one side, thereby realizing the exposure above the dough mixing tank 3, making it easy to take out the dough, and reducing the safety hazard brought by the need to flip up the material baffle guardrail 41. In terms of food, it ensures the safety protection of the dough during the dough mixing process, avoids external contamination, improves the operation convenience, ensures the safety of the operator, and reduces unnecessary interference.

[0057] Among them, the stirring and scraping mechanism 6 rotates along with the main shaft 22, not only stirring and kneading the dough, but also scraping the materials adhered to the inner wall of the dough mixing tank 3.

[0058] When the dough mixer is kneading dough, due to the humidity of the flour, there will be adhesion between the flour and the inner wall of the dough mixing tank 3 in the early stage, resulting in waste and increasing the cleaning process. To improve the dough kneading effect, the stirring and scraping mechanism 6 includes a cross 61 fixedly connected to the lower surface of the main shaft 22. Among them, scraping plates 62 are fixedly connected to the lower surfaces of the opposite two struts of the cross 61. The outer surface of the scraping plate 62 is slidably connected to the inner wall of the dough mixing tank 3. The surface of the scraping plate 62 in contact with the inner wall of the dough mixing tank 3 is made of rubber. When it rotates, it can peel off the adhered flour lumps and then mix them with the dough for kneading, thereby improving the dough kneading efficiency at the same time.

[0059] To improve the stirring effect of the dough, the stirring and scraping mechanism 6 further includes stirring rods 63 rotatably connected to the surfaces of the other opposite two struts of the cross 61 through bearings. A fixed gear 64 is rotatably sleeved on the outer surface of the main shaft 22. A driven gear 65 is fixedly sleeved on the upper outer surface of the stirring rod 63. The driven gear 65 meshes with the fixed gear 64. While the two stirring rods 63 revolve to stir the dough, they rotate around the meshed fixed gear 64 through the driven gear 65, which can drive the stirring rods 63 to rotate, so that the revolving stirring rods 63 keep rotating, thereby accelerating the stirring of the dough to make it take shape.

[0060] By setting the stirring and scraping mechanism 6, it not only kneads the dough but also scrapes the materials adhered to the inner wall of the dough mixing tank 3. During the adjustment process, while the stirring rods 63 are stirring the flour, the scraping plates 62 on the lower surface of the cross 61 revolve, and their rubber surfaces contact the inner wall of the dough mixing tank 3, so as to peel off the adhered flour lumps and then mix them with the dough for kneading, thereby improving the dough kneading efficiency at the same time and reducing the process of cleaning the inner wall of the dough mixing tank 3 in the later stage. That is, in terms of equipment and cleaning, the accumulation of flour residues is reduced, the difficult-to-clean flour lumps in the equipment are avoided from accumulating for a long time, the automatic scraping design reduces the manual cleaning time, improves the cleaning efficiency, and at the same time improves the hygiene standard of the equipment and reduces the risk of bacterial growth caused by adhered materials.

[0061] Among them, the adjusting mechanism 7 controls the relative rotation of the dough mixing tank 3 and the main shaft 22 and reciprocally adjusts the height of the dough mixing tank 3 when the stirring and scraping mechanism 6 processes the dough.

[0062] In order to improve the scraping effect of the scraping plate 62 and the dough kneading effect, the adjusting mechanism 7 includes a toothed ring 71 fixedly sleeved on the outer surface of the kneading tank 3. A support ring plate 73 is rotatably sleeved on the outer surface of the kneading tank 3. The lower surface of the ear plate of the support ring plate 73 is fixedly connected with a reduction motor 74. The outer surface of the output shaft of the reduction motor 74 is fixedly connected with a driving gear 75. The driving gear 75 meshes with the toothed ring 71. While the stirring and scraping mechanism 6 is working, the driving gear 75 is controlled to rotate by the reduction motor 74. Then, the engaged toothed ring 71 drives the kneading tank 3 to rotate on the surface of the support ring plate 73, so that the kneading tank 3 and the scraping plate 62 rotate relative to each other, increasing the scraping effect of the scraping plate 62. At the same time, the rotation of the dough can be controlled to improve the stirring effect.

[0063] In order to fully stir the dough at the bottom of the kneading tank 3, the adjusting mechanism 7 further includes a movable groove 76 opened on one side surface of the middle beam of the numerical control beam 2. The inner wall of the movable groove 76 is rotatably connected with an adjusting screw 72 through a bearing. One end of the support ring plate 73 is threadedly sleeved on the outer surface of the adjusting screw 72, and its outer surface is slidably connected with the inner wall of the movable groove 76. After the numerical control beam 2 controls the adjusting screw 72 to rotate, the height of the support ring plate 73 can be adjusted, so as to control the height adjustment of the kneading tank 3. And the kneading tank 3 is supported by the buffer telescopic rod 21 to bear the weight, thereby improving the stability of its height adjustment.

[0064] By setting the adjusting mechanism 7, it controls the kneading tank 3 to rotate relative to the main shaft 22, and reciprocally adjusts the height of the kneading tank 3 when the stirring and scraping mechanism 6 processes the dough. During the adjustment process, the numerical control beam 2 controls the adjusting screw 72 to rotate to adjust the height of the support ring plate 73, so as to control the height adjustment of the kneading tank 3, thereby realizing the full stirring of the dough. And the engaged toothed ring 71 drives the kneading tank 3 to rotate on the surface of the support ring plate 73, so that the kneading tank 3 and the scraping plate 62 rotate relative to each other, increasing the scraping effect of the scraping plate 62. At the same time, the rotation of the dough can be controlled to improve the stirring effect. The full stirring of the dough ensures the uniformity and quality of the dough, and improves the taste and quality of the food.

[0065] Refer to Figures 1-10 , a stirring method of a stirring device of a tilting kneader, including the following steps:

[0066] S1. When the tilting kneader is kneading dough, put the raw materials into the kneading tank 3, and then control the servo motor 50 to start, so that it controls the driving rod 51 to rotate, so that the free end of the driving rod 51 pushes the first group of articulated linkages 48 to unfold. Since the multiple articulated linkages 48 are connected to each other, linkage is realized;

[0067] S2. The V-shaped articulated connecting rods 48 in each group open on the upper surface of the dough mixing tank 3, thereby enabling the linkage block 47 to rotate within the annular card slot 46, so that the material blocking guardrail 41 completes rotation. At this time, the support rod 45 rotates within the sliding card slot 44 of the support ring 43. Then, after the stacked material blocking guardrails 41 are unfolded to form an annular material blocking guardrail 41, it completes the protective function.

[0068] S3. After the material blocking guardrail 41 is closed, the numerical control beam 2 controls the main shaft 22 to rotate, which drives the cross 61 to rotate. Then, while the two stirring rods 63 revolve to stir the dough, they rotate around the engaged fixed gear 64 through the driven gear 65, so that the stirring rods 63 can be driven to rotate, enabling the revolving stirring rods 63 to maintain rotation, thereby accelerating the stirring of the dough to make it take shape.

[0069] S4. While the stirring rods 63 are stirring the flour, the scraping plate 62 on the lower surface of the cross 61 revolves, and its rubber surface contacts the inner wall of the dough mixing tank 3, thereby peeling off the adhered flour lumps, and then making them be stirred and kneaded with the dough, thereby improving the kneading efficiency at the same time.

[0070] S5. While the stirring and scraping mechanism 6 is working, the reduction motor 74 controls the driving gear 75 to rotate, and the engaged toothed ring 71 drives the dough mixing tank 3 to rotate on the surface of the support ring plate 73, so that the dough mixing tank 3 and the scraping plate 62 rotate relative to each other, increasing the scraping effect of the scraping plate 62, and at the same time being able to control the rotation of the dough to improve the stirring effect.

[0071] S6. While kneading the dough, the numerical control beam 2 controls the adjusting screw 72 to rotate, so as to adjust the height of the support ring plate 73, thereby controlling the dough mixing tank 3 to achieve height adjustment, and then realizing the full stirring of the dough.

[0072] S7. After the dough is stirred, the servo motor 50 controls the driving rod 51 to act in the reverse direction. When the included angle of the V-shaped articulated connecting rods 48 becomes smaller, they contract, driving the material blocking guardrail 41 to contract to one side, thereby exposing the upper part of the dough mixing tank 3, making it easy to take out the dough. When taking out the dough, the rotary encoder 13 outputs corresponding electrical signals according to the rotation angle or position, which is used to measure the rotation angle of the rotating shaft 11. Thus, after the numerical control table 1 controls the rotation of the rotating shaft, the turning plate 12 can drive the dough mixing tank 3 to turn over, thereby realizing the pouring action.

[0073] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
