Description

Technical Field

[0001] This application relates to the field of pastry making, and particularly to a mixing and stirring feeding device. Background Art

[0002] Dessert pastries are very popular due to their rich flavors, delicate appearance, and pleasant eating experience. Their appeal lies in satisfying people's craving for sweets and is also a symbol of socializing, celebration, and enjoyment. The target audience is wide, including people of all ages and social backgrounds. Whether as a dessert after a meal, a snack for social activities, or a celebratory food for special occasions, they are deeply loved by people.

[0003] In order to diversify the flavors of pastries, it is usually necessary to mix raw materials such as cream with fresh milk, jam (puree), or nut crumbs, etc., so that their flavors and appearance quality can better meet the needs of consumers. In the existing processing method, the operator first needs to put different types of raw materials into the mixing tank, use the mixing equipment to mix the different types of raw materials evenly, and then use the discharging equipment to orderly release the evenly mixed mixture onto the cake blank or the pastry skin. Through subsequent processing procedures, the mixture is coated on the surface of the cake blank / or the mixture is wrapped inside the pastry skin.

[0004] However, in this process, in order to make different types of raw materials mix evenly with each other, the mixing equipment needs a relatively long time to mix the different types of raw materials evenly. After mixing is completed, the mixture in the mixing equipment needs to be collected again and put into the discharging equipment, which is cumbersome to operate and takes a relatively long time for the whole process. At the same time, because the mixture is mostly in a viscous state, during the transfer process of the mixture, the mixture will adhere to the container, causing waste, and there is room for improvement. Summary of the Utility Model

[0005] In order to improve the production efficiency of mixing different types of raw materials, this application provides a mixing and stirring feeding device.

[0006] The mixing and stirring feeding device provided by this application adopts the following technical solutions:

[0007] A hybrid stirring and feeding device, comprising a frame, a feeding trough and a discharging pipe which are successively arranged on the frame. The discharging port of the feeding trough communicates with the feeding port of the discharging pipe. The feeding trough is fixedly connected to the discharging pipe. The feeding trough is used for accommodating raw materials, and the discharging pipe is used for discharging the mixed raw materials. The feeding trough is provided with a primary stirring assembly, which includes a first driving member and a stirring screw. The first driving member is arranged on the frame outside the feeding trough, and the stirring screw is rotatably carried in the feeding trough. The first driving member is used to drive the stirring screw to rotate. The discharging pipe is provided with a secondary stirring assembly, which includes a feeding screw and a second driving member. The second driving member is arranged on the frame outside the discharging pipe, and the feeding screw is rotatably carried in the discharging pipe. The second driving member is used to drive the feeding screw to rotate.

[0008] By adopting the above technical solution, after the operator puts different types of raw materials into the feeding trough, the first driving member drives the stirring screw to preliminarily stir and mix the raw materials. Subsequently, the preliminarily stirred raw materials reach the discharging pipe. At this time, the second driving member drives the feeding screw to perform secondary stirring on the preliminarily mixed raw materials, so that different types of raw materials are evenly mixed, and at the same time, the discharging process of the raw materials is completed. Compared with the method of first mixing different types of raw materials evenly and then putting them into the feeding device for discharging, the above process can complete the stirring and mixing of the raw materials and the discharging process at the same time, with simple operation, and reduces the loss during the transfer process of the raw materials, which plays a positive guiding role in improving the production efficiency of mixing different types of raw materials.

[0009] Preferably, the primary stirring assembly further includes a first transmission shaft and a second transmission shaft. The first transmission shaft and the second transmission shaft are rotatably carried in the feeding trough along the same axis from the inner side wall of the feeding trough to its discharging port direction. The stirring screw is detachably arranged between the first transmission shaft and the second transmission shaft, and the first driving member drives the first transmission shaft to rotate.

[0010] By adopting the above technical solution, when it is necessary to replace or maintain the stirring screw, the stirring screw can be simply disassembled between the first transmission shaft and the second transmission shaft. At the same time, since the first transmission shaft and the second transmission shaft are on the same axis, the adjustment time when setting the stirring screw on the first transmission shaft and the second transmission shaft is reduced, and the yaw during the rotation of the stirring screw caused by the first transmission shaft, the stirring screw and the second transmission shaft not being on the same axis is reduced.

[0011] Preferably, clamping grooves are respectively formed at two ends of the stirring screw rod, clamping rods are respectively arranged at the joints of the first transmission shaft and the second transmission shaft and the stirring screw rod, and the clamping grooves are in clamping fit with the clamping rods.

[0012] By adopting the above technical solution, when it is necessary to replace or maintain the stirring screw rod, the stirring screw rod can be removed along the clamping rod. At the same time, due to the clamping fit between the clamping rod and the clamping groove, when the first driving member drives the first transmission shaft to rotate, the probability of the occurrence of shaking or slipping caused by the gap at the joint of the stirring screw rod and the first transmission shaft and the second transmission shaft is reduced.

[0013] Preferably, a positioning piece and a pressing block are arranged on the first transmission shaft. The positioning piece is fixedly connected to the first transmission shaft coaxially. The pressing block is slidably connected between the clamping rod and the positioning piece, and a pressing spring is arranged between the positioning piece and the pressing block. The pressing spring is used to provide elastic force for the pressing block to press the stirring screw rod.

[0014] By adopting the above technical solution, the pressing spring is used to realize the close fit between the pressing block and the stirring screw rod, further reducing the gap between the stirring screw rod and the first transmission shaft, thereby reducing the shaking during the rotation of the stirring screw rod.

[0015] Preferably, a clamping groove is formed on the surface of the pressing block in contact with the stirring screw rod. The clamping groove is recessed downward from the upper surface of the pressing block along its thickness direction, and the diameter of the clamping groove is larger than the diameter of the stirring screw rod.

[0016] By adopting the above technical solution, the operator presses the pressing block, thereby forcing the pressing spring to contract. When the stirring screw rod is installed between the first transmission shaft and the second transmission shaft again, the pressing block is released. Under the action of the elastic force of the pressing spring, the pressing block is in close fit with the stirring screw rod, and one end of the stirring screw rod in contact with the pressing block is clamped in the clamping groove. The stirring screw rod is limited by the clamping groove, reducing the probability of the stirring screw rod falling off along the clamping rod due to excessive force on the stirring screw rod during rotation.

[0017] Preferably, an auxiliary feeding roller is rotatably supported at the discharge port of the feeding trough. The auxiliary feeding roller is perpendicular to the spatial position relationship of the stirring screw rod, and the auxiliary feeding roller is located above the stirring screw rod.

[0018] By adopting the above technical solution, when the first driving member drives the first transmission shaft to rotate, thereby driving the stirring screw to drive the second transmission shaft to rotate, the stirring screw stirs the raw materials in the feeding trough. When the raw materials reach between the stirring screw and the auxiliary feeding roller, the rolling friction force generated by the raw materials between the stirring screw and the auxiliary feeding roller is utilized to drive the auxiliary feeding roller to rotate. The cooperation of the auxiliary feeding roller and the stirring screw provides further stirring for the raw materials. At the same time, the auxiliary feeding roller is used to guide the conveying direction of the raw materials, facilitating the raw materials to enter the discharging pipe.

[0019] Preferably, a plurality of convex strips are evenly distributed in a ring along the length direction of the auxiliary feeding roller.

[0020] By adopting the above technical solution, since the auxiliary feeding roller is not driven by a power source, the use of a plurality of convex strips increases the friction force of the cooperation between the auxiliary feeding roller and the stirring screw, reducing the probability of slippage occurring when the auxiliary feeding roller rotates.

[0021] Preferably, the discharging pipe includes a discharging section and a material storage section. One end of the discharging section is connected to the discharging port of the feeding trough, and the free end of the discharging section is detachably connected to the feeding port of the material storage section. A plurality of squeezing ports are provided on the material storage section, and all the plurality of squeezing ports are used to release the raw materials in the material storage section.

[0022] By adopting the above technical solution, after the feeding screw stirs and mixes the raw materials again, the finally mixed raw materials will reach the material storage section. The raw materials in the material storage section are released into the stuffing injection machine or oil injection machine through a plurality of squeezing ports on the material storage section, facilitating the subsequent processing procedures. Moreover, the material storage section and the discharging section are detachably connected, facilitating the cleaning and maintenance of the inside of the discharging section and the material storage section.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The operator puts different types of raw materials into the feeding trough, and then the first driving member drives the stirring screw to perform preliminary stirring and mixing on the raw materials. Subsequently, the second driving member drives the feeding screw to perform secondary stirring on the preliminarily mixed raw materials, so that different types of raw materials are evenly mixed. This process not only completes the mixing but also simultaneously performs the feeding operation. Compared with mixing different types of raw materials first and then feeding, this method is more convenient to operate, and at the same time reduces the loss during the transfer of raw materials, thereby improving the production efficiency;

[0025] 2. When the operator presses the clamping block, the compression spring is forced to contract. When the stirring screw is reinstalled between the first transmission shaft and the second transmission shaft, the clamping block is released. At this time, the clamping block is subjected to the elastic force of the compression spring and fits closely with the stirring screw. One end of the stirring screw in contact with the clamping block is clamped in the clamping groove, and the stirring screw is limited by the clamping groove. The purpose of this design is to reduce the probability of the excessive force on the stirring screw during rotation and the situation of the stirring screw falling off along the clamping rod.

[0026] 3. After the mixed raw materials reach the storage section, they will no longer be stirred and are released into the stuffing machine or oil injection machine through several material extrusion ports, which solves to a certain extent the problem of increased stirring time caused by the re-stirring of the mixed raw materials after the mixing is completed. At the same time, the storage section and the discharging section are detachably connected, which is convenient for cleaning the storage section and the discharging section.

Detailed Description of the Embodiment

[0031] The following will Figures 1 - 3 further describe the present application in detail with reference to the attached

[0032] An embodiment of the present application discloses a mixing and stirring and discharging device. Refer to Figure 1 and Figure 3, A hybrid stirring and feeding device includes a frame 1, a feeding trough 2 and a discharging pipe 3 which are sequentially arranged on the frame 1. The discharging port of the feeding trough 2 is communicated with the feeding port of the discharging pipe 3. The feeding trough 2 is used for accommodating raw materials. A primary stirring assembly 4 is arranged in the feeding trough 2, and a secondary stirring assembly is arranged in the discharging pipe 3. The primary stirring assembly 4 includes a first driving member and a stirring screw 42, and the secondary stirring assembly includes a second driving member and a feeding screw. The first driving member and the second driving member are respectively arranged on the frame 1 outside the feeding trough 2 and the discharging pipe 3. After the first driving member drives the stirring screw 42 to preliminarily stir the raw materials placed in the feeding trough 2, the raw materials reach the secondary stirring assembly, and the second driving member drives the feeding screw to rotate, so that the raw materials are stirred evenly for the second time. The evenly stirred raw materials are released from the discharging end of the discharging pipe 3 onto the cake blank or the dough sheet, and through subsequent processing procedures, the raw materials are coated on the cake blank or wrapped in the dough sheet. The operation is simple, and the loss during the transfer of the mixture to different containers is reduced, which plays a positive guiding role in improving the mixing production efficiency of different types of raw materials.

[0033] Refer to Figure 1 and Figure 2 , The primary stirring assembly 4 further includes a first transmission shaft 43 and a second transmission shaft 44. The first transmission shaft 43 and the second transmission shaft 44 are respectively rotatably supported on the inner side wall of the feeding trough 2 along the same axis from the inner side wall of the feeding trough 2 to its discharging port. The stirring screw 42 is detachably arranged between the first transmission shaft 43 and the second transmission shaft 44, and the first driving member drives the first transmission shaft 43 to rotate.

[0034] Specifically, the first transmission shaft 43 penetrates through the feeding trough 2 and is rotatably connected to the feeding trough 2, and a mounting plate (not shown in the figure) is installed at the discharging port of the feeding trough 2. The second transmission shaft 44 is rotatably supported on the mounting plate. At the same time, the first driving member is set as a driving motor 41, and the output shaft of the driving motor 41 is coaxially fixed to the first transmission shaft 43. When the stirring screw 42 is installed between the first transmission shaft 43 and the second transmission shaft 44, the first transmission shaft 43 can be driven to rotate by the driving motor 41, so that the stirring screw 42 installed between the first transmission shaft 43 and the second transmission shaft 44 rotates, realizing the preliminary stirring of the raw materials placed in the feeding trough 2.

[0035] Further, clamping grooves 421 are respectively formed at both ends of the stirring screw 42. Clamping rods 6 are respectively arranged at the joints of the first transmission shaft 43 and the second transmission shaft 44 and the stirring screw 42, and the clamping grooves 421 are in clamping fit with the clamping rods 6. Among them, the clamping grooves 421 are integrally formed with the stirring screw 42 through machining by a machine tool. At the same time, the two clamping rods 6 are perpendicular to the first transmission shaft 43 and the second transmission shaft 44 and respectively penetrate through the first transmission shaft 43 and the second transmission shaft 44. When it is necessary to disassemble the stirring screw 42, only the clamping connection between the clamping groove 421 and the clamping rod 6 needs to be released, and then the stirring screw 42 can be taken out along the feeding trough 2; when it is necessary to install the stirring screw 42, only the clamping groove 421 and the clamping rod 6 need to be clamped again, so that the stirring screw 42 can rotate synchronously with the first transmission shaft 43. This structure facilitates the maintenance and cleaning of the stirring screw 42 or the inside of the feeding trough 2.

[0036] At the same time, due to the gap between the clamping groove 421 and the clamping rod 6, when the stirring screw 42 rotates, the clamping groove 421 on the stirring screw 42 will continuously rub against the clamping rod 6, thereby accelerating the wear speed of the stirring screw 42. At the same time, if the cooperation between the clamping groove 421 and the clamping rod 6 is unstable, the stirring screw 42 has a probability of falling off at the joints of the first transmission shaft 43 and the second transmission shaft 44. Therefore, in order to reduce the probability of the above situation occurring, a positioning piece 431 and a pressing block 432 are arranged on the first transmission shaft 43. The positioning piece 431 is coaxially and fixedly connected to the first transmission shaft 43. The pressing block 432 is slidably connected between the clamping rod 6 and the positioning piece 431, and a pressing spring 433 is arranged between the positioning piece 431 and the pressing block 432. When the stirring screw 42 is clamped and connected to the first transmission shaft 43 and the second transmission shaft 44 through the clamping groove 421, affected by the elastic force of the pressing spring 433, the pressing block 432 will fit against the stirring screw 42, so that both ends of the stirring screw 42 are in a constrained state, thereby reducing the shaking of the stirring screw 42 during rotation.

[0037] Correspondingly, referring to Figure 3, if the first transmission shaft 43, the second transmission shaft 44 and the stirring screw 42 are not on the same axis, when the stirring screw 42 rotates, some areas of the stirring screw 42 will continuously rub against the inner wall of the feeding trough 2, accelerating the wear rate of the stirring screw 42. At the same time, the debris generated during the friction between the stirring screw 42 and the feeding trough 2 will be mixed into the raw materials, affecting food safety. Therefore, a clamping groove 7 is formed on the surface of the clamping block 432 in contact with the stirring screw 42. The clamping groove 7 is machined downward along its thickness direction from the surface of the clamping block 432 in contact with the stirring screw 42 by a machine tool, and the diameter of the clamping groove 7 is larger than the diameter of the stirring screw 42. At this time, the stirring screw 42 is in transitional fit with the clamping groove 7 (that is, the stirring screw 42 can be freely taken out along the clamping groove 7 / or the stirring screw 42 can be placed in the clamping groove 7). Therefore, the installation position of the stirring screw 42 is limited by the clamping groove 7, reducing the probability of the stirring screw 42 falling off between the first transmission shaft 43 and the second transmission shaft 44, and effectively solving the above problems at the same time.

[0038] Refer to Figure 1 , a rotating bearing is arranged at the discharge port of the feeding trough 2, and an auxiliary feeding roller 8 is arranged. The spatial position relationship between the auxiliary feeding roller 8 and the stirring screw 42 is perpendicular, and the auxiliary feeding roller 8 is located above the stirring screw 42. There is a gap for the raw materials to pass between the auxiliary feeding roller 8 and the stirring screw 42. Therefore, when the stirring screw 42 starts to stir the raw materials in the feeding trough 2, some raw materials will pass through the gap between the stirring screw 42 and the auxiliary feeding roller 8, driving the auxiliary feeding roller 8 to rotate. Through the cooperation of the auxiliary feeding roller 8 and the stirring screw 42, further stirring and mixing of the raw materials are provided. At the same time, through the guiding action of the auxiliary feeding roller 8, the raw materials passing through the gap between the auxiliary feeding roller 8 and the stirring screw 42 can quickly enter the discharge pipe 3, reducing the probability of the raw materials that have been mixed being stirred again, and saving the stirring time.

[0039] At the same time, since the auxiliary roller is not driven by a power source and only drives the auxiliary feeding roller 8 to rotate by using the rolling friction generated between the stirring screw 42 and the auxiliary feeding roller 8 by the raw materials, if the surface of the auxiliary feeding roller 8 is in a smooth state, when the raw materials pass through the gap between the auxiliary feeding roller 8 and the stirring screw 42, the auxiliary feeding roller 8 may slip, reducing the mixing efficiency. Therefore, in order to effectively solve the above problems, a number of convex strips 81 are evenly distributed in a ring along the length direction of the auxiliary feeding roller 8. The number of convex strips 81 and the auxiliary feeding roller 8 are integrally formed by machining with a machine tool, reducing the probability of the convex strips 81 falling off along the auxiliary feeding roller 8. At this time, the cross-sectional shape of the auxiliary feeding roller 8 in cooperation with the number of convex strips 81 is gear-shaped, increasing the friction force between the auxiliary feeding roller 8 and the contact surface of the raw materials, and reducing the probability of the auxiliary feeding roller 8 slipping when rotating.

[0040] Reference Figure 1 As shown in Figure 1 , the discharging pipe 3 includes a discharging section 31 and a material storage section 32. One end of the discharging section 31 is connected to the discharging port of the feeding trough 2, and the free end of the discharging section 31 is detachably connected to the feeding port of the material storage section 32. A plurality of material extrusion openings 321 are provided on the material storage section 32, and all of the plurality of material extrusion openings 321 are used to release the raw materials in the material storage section 32.

[0041] Specifically, the feeding screw (not shown in the figure) is rotatably carried in the discharging section 31, and the second driving member is set as a reduction motor 51. The reduction motor 51 is installed on the frame 1 outside the discharging section 31, and the output shaft of the reduction motor 51 is coaxially fixed to the feeding screw. Therefore, when the output shaft of the reduction motor 51 rotates, the feeding screw coaxially fixed to the output shaft of the reduction motor 51 rotates synchronously, performing secondary mixing and stirring on the raw materials flowing out of the discharging port of the feeding trough 2, further enhancing the mixing degree of the raw materials.

[0042] Meanwhile, a flange 9 is installed at the connection between the discharging section 31 and the material storage section 32. The discharging section 31 and the material storage section 32 are fixedly connected by bolts through the flange 9. When maintenance and cleaning of the discharging section 31 and / or the material storage section 32 are required, only the flange 9 needs to be disassembled to separate the discharging section 31 and the material storage section 32.

[0043] Furthermore, the plurality of "material extrusion openings 321" are conventional discharging devices. Usually, a controller is used to control the opening and closing size and frequency of the discharging device valve, so as to realize the orderly release of the raw materials in the material storage section 32. This is prior art, and its specific composition, quantity and working mode will not be elaborated here too much.

[0044] Therefore, after the raw materials are secondarily stirred by the reduction motor 51 cooperating with the feeding screw, the raw materials enter the material storage section 32 for storage, and the raw materials are orderly released into the stuffing injection machine or oil injection machine (which is a conventional pastry production and processing equipment, and its specific composition and working principle will not be elaborated here too much) through the material extrusion openings 321, facilitating the subsequent processing procedures.

[0045] The implementation principle of the mixing, stirring and discharging device in the embodiment of the present application is as follows: First, the operator puts different types of raw materials into the feeding trough 2, starts the first driving member to drive the stirring screw 42 to perform preliminary stirring and mixing on the raw materials. Subsequently, the mixed raw materials enter the discharging pipe 3 through the discharging pipe 3, and the second driving member starts to work, driving the feeding screw to perform secondary stirring on the preliminarily mixed raw materials to make the different types of raw materials mix evenly. Subsequently, the raw materials are orderly released into the stuffing injection machine or oil injection machine through the discharging port of the discharging pipe 3. Compared with the conventional method of separately mixing and collecting different types of raw materials and then discharging the raw materials, the operation steps are simplified, the loss during the transfer process of the raw materials is reduced, and it helps to improve the production efficiency of the mixing of different types of raw materials.

[0046] The above are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application shall be covered within the protection scope of this application.
