Description

Technical Field

[0001] This application relates to the field of ice cream production equipment technology, and in particular to a granule mixer. Background Technology

[0002] In the continuous production of ice cream, in order to enrich the texture and enhance the flavor diversity, it is usually necessary to evenly mix solid particulate materials such as fruit pieces and nut pieces into the frozen ice cream base. As a supporting equipment of the ice cream production line, the main function of the particulate mixer is to receive the ice cream base output from the preceding equipment and mix the particulate materials with the base in a preset ratio to obtain an ice cream base mixed with fruit pieces or nuts.

[0003] Existing pellet mixers typically include a frame on which a feed pipe, a discharge pipe, a hopper, and a mixing pump are mounted. The hopper contains a stirring mechanism to prevent pellet material from settling and agglomerating. The stirred pellet material is fed into the mixing pump, while ice cream syrup is fed into the mixing pump through the feed pipe. After the pellets and syrup are mixed in the mixing pump, they are output through the discharge pipe.

[0004] In actual production, the physical properties of fruit pieces and nut pieces commonly used in ice cream production differ significantly: fruit pieces are soft and loose in structure, and are easily broken, deformed, or release water during stirring, which leads to the destruction of the integrity of the particle shape and affects the appearance and taste of the product; nut pieces are hard and dense, and are prone to sedimentation, clumping, or even bridging, requiring strong stirring intensity to break up clumps and prevent sedimentation.

[0005] However, the existing mixing mechanism inside the hopper can only set a fixed mixing state for a single type of granular material, and cannot adapt the mixing state according to the different characteristics of fruit granules and nuts. If the strong mixing state adapted to nuts is used to process fruit granules, it will lead to a large number of fruit granules breaking. If the weak mixing state adapted to fruit granules is used to process nuts, it cannot effectively solve the problem of nut clumping and sedimentation. In addition, the existing hopper cannot mix two types of granules at the same time. Therefore, the existing granule mixer has poor applicability and obvious shortcomings. Summary of the Invention

[0006] In order to improve the applicability of the pellet mixer and enable it to meet the mixing needs of different types of materials, this application provides a pellet mixer.

[0007] The pellet mixer provided in this application adopts the following technical solution: A pellet mixer includes a frame on which a hopper, a feed pipe, a discharge pipe, and a mixing pump are mounted. The hopper is connected to the mixing pump via a conveying pipe. A partition is provided inside the hopper, and the opposite end faces of the partition and the inner sidewall of the hopper enclose a nut zone and a fruit zone. A stirring mechanism is provided inside the hopper, comprising a first stirring shaft rotatably connected to the nut zone and a second stirring shaft rotatably connected to the fruit zone. Multiple stirring elements are provided on the outer surfaces of both the first and second stirring shafts. An installation cavity is formed within the partition, and the ends of the first and second stirring shafts extend into the installation cavity and are connected by a reduction gear set. A drive motor is mounted on the hopper, and the drive motor drives the reduction gear set to rotate via a transmission assembly.

[0008] By adopting the above technical solution, when two different types of materials need to be mixed, workers add fruit granules to the fruit granule area and nut granules to the nut area. During stirring, the drive motor drives the reduction gear set to rotate through the transmission component. When the reduction gear set rotates, the rotation speed of the second stirring shaft is lower than that of the first stirring shaft. In this way, the granular materials in the nut area and the fruit granule area are in different stirring speed environments, reducing the possibility of fruit granules breaking, deforming or releasing water due to excessive rotation speed, and reducing the possibility of caking and deposition in the nut area, thus improving the applicability of the fruit granule mixer.

[0009] Optionally, the reduction gear set includes a first gear coaxially disposed at the end of the first stirring shaft, and a second gear coaxially disposed at the end of the second stirring shaft that meshes with the first gear. The first gear has fewer teeth than the second gear. The transmission assembly includes a transmission shaft rotatably connected in the mounting cavity. A drive gear coaxially disposed on the transmission shaft that meshes with the first gear. The output shaft of the drive motor and the transmission shaft are connected by a bevel gear set.

[0010] By adopting the above technical solution, when mixing two different types of materials, the drive motor drives the transmission shaft to rotate through the bevel gear set, the transmission shaft drives the drive gear to rotate synchronously, and the drive gear drives the first gear and the first stirring shaft to rotate through meshing, thereby realizing the stirring operation in the nut area. Since the number of teeth of the first gear is less than that of the second gear, the two form a reduction gear set. When the first gear rotates, it will drive the second gear and the second stirring shaft to rotate at a speed lower than that of the first stirring shaft, thereby realizing the slow stirring operation in the nut area.

[0011] Optionally, the ends of the first stirring shaft and the second stirring shaft are connected by a gear set of the same speed. The gear set of the same speed includes a third gear disposed at the end of the first stirring shaft and a fourth gear disposed at the end of the second stirring shaft that meshes with the third gear. The third gear and the fourth gear have the same module and are meshed with the drive gear. An adjustment component is disposed on the transmission shaft to drive the drive gear to move along the axis of the transmission shaft.

[0012] By adopting the above technical solution, when it is necessary to mix the same type of material in the nut and fruit granule areas, the worker can adjust the component to drive the drive gear to mesh with the third gear. When the drive motor starts, it will drive the first and second stirring shafts to rotate at the same speed through the transmission of the drive gear and the same speed gear set. This allows the operator to simultaneously feed the same type of granular material into the nut and fruit granule areas, making full use of the space of the dual chambers, increasing the storage capacity of a single material and the mixing efficiency, thereby further improving the applicability of the mixer.

[0013] Optionally, the drive shaft is provided with an adjustment groove along the axial direction, and the adjustment assembly includes an adjustment block slidably connected in the adjustment groove. The inner sidewalls opposite to each other of the adjustment groove are respectively provided with a first electromagnetic block and a second electromagnetic block. The adjustment block is made of a magnetically conductive material that attracts and cooperates with the first electromagnetic block and the second electromagnetic block. When the first electromagnetic block attracts the adjusting block, the adjusting block is located in the first position, and the driving gear meshes with the first gear; When the second electromagnetic block attracts the adjusting block, the adjusting block is in the second position, and the drive gear meshes with the third gear.

[0014] By adopting the above technical solution, the worker selectively energizes the first or second electromagnetic block to drive the adjusting block to move along the adjusting groove. When the adjusting block moves, it drives the drive gear to move, thereby enabling the drive gear to mesh with the first or third gear, thus realizing the change of the rotation mode of the first and second stirring shafts.

[0015] Optionally, the stirring component includes a first stirring blade and a second stirring blade distributed circumferentially along the first stirring shaft or the second stirring shaft. The first stirring blade is a flexible blade, and the second stirring blade is a rigid blade. The outer surfaces of the first stirring shaft and the second stirring shaft are provided with connecting seats that correspond one-to-one with a plurality of the first stirring blades and the second stirring blades. An adjusting shaft is rotatably connected to the connecting seat. The first stirring blades and the second stirring blades are fixedly connected to the adjusting shaft. The nut area and the particle area are provided with a switching component that drives the adjusting shaft to rotate, so that the first stirring blades and the second stirring blades can switch between a working state and a retracted state.

[0016] By adopting the above technical solution, before production, workers drive the adjusting shaft to rotate via a switching component according to the characteristics of the material to be mixed. When the adjusting shaft rotates, it drives the first and second mixing blades to switch states synchronously: when processing soft materials such as fruit granules, the switching component controls the first mixing blade to be in the working state and the rigid second mixing blade to be in the retracted state. The low shear characteristics of the flexible blades gently disturb the material, reducing the possibility of fruit granules breaking due to excessive mixing force. When processing hard materials such as nuts, the switching component controls the rigid second mixing blade to be in the working state and the flexible first mixing blade to be in the retracted state. The strong mixing ability of the rigid blades breaks up nut lumps and prevents sedimentation and bridging. When two materials need to be processed simultaneously, they can be adapted separately through the corresponding switching components of the two shafts to achieve differentiated mixing. In this way, workers can quickly adapt to the mixing needs of materials with different characteristics by simply switching the components, further improving the applicability of the mixer.

[0017] Optionally, the first and second stirring shafts have drive cavities corresponding to the plurality of stirring elements. The switching assembly includes a switching seat slidably connected in the drive cavity. The switching seat is provided with a toothed belt corresponding to the first and second stirring blades in the same stirring element. Each adjusting shaft is provided with an adjusting gear that meshes with the toothed belt. The end of the toothed belt away from the switching seat is fixedly embedded in the tooth gap of the adjusting gear. A third electromagnetic block is provided on the inner sidewall of the drive cavity. The switching seat is made of a magnetically conductive material that is attracted and engaged with the third electromagnetic block. Each adjusting shaft has a torsion spring sleeved at both opposite ends for resetting. In the natural state of the torsion spring, the first stirring blade is in the retracted state and the second stirring blade is in the working state. When the third electromagnetic block attracts the switching seat, the first stirring blade is in the working state and the second stirring blade is in the retracted state.

[0018] By adopting the above technical solution, when it is necessary to stir nuts, the worker energizes the third electromagnetic block. The magnetic force generated by the third electromagnetic block attracts the switching seat to slide along the drive cavity. The switching seat drives the adjusting gear to rotate by pulling the toothed belt. At this time, the torsion spring is compressed, and the rotation of the adjusting gear drives the adjusting shaft to rotate 90°. The adjusting shaft drives the first stirring blade and the second stirring blade to rotate. At this time, the first stirring blade rotates to the working state, and the second stirring blade rotates synchronously to the retracted state. In this way, the hard first stirring blade participates in stirring the nuts. When it is necessary to stir the fruit pieces, the worker controls the third electromagnetic block to de-energize. At this time, the torsion spring resets and drives the adjusting shaft to rotate in the opposite direction. The adjusting shaft drives the adjusting gear to rotate, and the adjusting gear drives the toothed belt to wind onto the adjusting gear. At the same time, under the gravity of the switching seat and the pull of multiple toothed belts, it resets. During this process, the first stirring blade resets to the retracted state, and the second stirring blade resets to the working state. In this way, the soft second stirring blade participates in stirring the fruit pieces.

[0019] Optionally, the drive cavity is provided with a support gear that corresponds one-to-one with the plurality of toothed belts, and the teeth of the toothed belts mesh with the support gears.

[0020] By adopting the above technical solution, during the process of the switching seat driving the toothed belt to move, the support gear provides support and guides the toothed belt, while simultaneously tensioning the toothed belt, reducing the possibility of the toothed belt shaking, deviating, or loosening during transmission, and ensuring smooth operation of the switching process between the first and second stirring blades.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This application divides the hopper into a fruit granule zone and a pellet zone by a partition, and sets up a reduction gear set to drive the first and second stirring shafts to rotate at different speeds. This allows the hopper to stir different types of materials at the same time, and the pellet materials in the nut zone and the fruit granule zone are in an environment with different stirring speeds, reducing the possibility of fruit granules breaking, deforming or leaking water due to excessive rotation speed, while reducing the possibility of caking and deposition in the nut zone, thus improving the applicability of the fruit granule mixer. This application, by setting up an adjustment component, a transmission component, and a gear set of the same speed, allows the worker to drive the drive gear to move to a transmission connection with the gear set of the same speed when it is necessary to mix the same type of material in the nut zone and the fruit granule zone. This enables the first and second mixing shafts to rotate at the same speed, allowing the same type of granular material to be fed into the nut zone and the fruit granule zone at the same time. The space of the dual chamber is fully utilized, thereby further improving the applicability of the mixer. This application sets up a switching component to switch the working state of the first and second stirring blades. The operator drives the adjusting shaft to rotate according to the characteristics of the material to be stirred by the switching component. When the adjusting shaft rotates, it drives the first and second stirring blades to switch states synchronously. When two materials need to be processed at the same time, they can be adapted separately by the corresponding switching components of the two shafts to achieve differentiated stirring. In this way, the operator can quickly adapt to the stirring needs of materials with different characteristics by simply switching the component, which further improves the applicability of the mixer.

[0029] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0030] This application discloses a particle mixer.

[0031] Reference Figure 1 and Figure 2 A pellet mixer includes a frame 1, on which a feed pipe 101, a mixing pump 102, and a discharge pipe 103 are mounted. The feed end and discharge end of the mixing pump 102 are connected to the feed pipe 101 and the discharge pipe 103, respectively. The feed end of the feed pipe 101 is sealed and connected to the discharge end of the preceding continuous freezing machine to receive the ice cream mixture continuously output by the freezing machine. The discharge pipe 103 is used to transport the mixed ice cream mixture to the subsequent forming or packaging process. In this embodiment, the mixing pump 102 adopts existing mature equipment, and its specific structure, working principle and internal composition are all existing technologies, which will not be described in detail here.

[0032] Reference Figure 1 and Figure 2A hopper 2 is fixedly installed on the frame 1. An end cover 21 is rotatably connected to the top of the hopper 2. The end cover 21 can be flipped open and closed relative to the hopper 2 so that the operator can add granular materials and seal the hopper 2. A stirring mechanism 3 for stirring materials is set inside the hopper 2. A conveying pipe 22 is connected to the outer side of the hopper 2. A temporary storage box 104 is installed on the frame 1. The end of the conveying pipe 22 away from the hopper 2 is connected to the inner cavity of the temporary storage box 104. The outlet of the temporary storage box 104 is connected to the inner cavity of the mixing pump 102 so as to realize the conveying of granular materials to the mixing pump 102.

[0033] Reference Figure 1 and Figure 2 A control panel 4 is installed on the rack 1. The control panel 4 integrates a control module (not shown in the figure). The control module is electrically connected to the power equipment on the rack 1. The specific control methods and principles are existing technologies and will not be described in detail in this embodiment.

[0034] When the equipment is working, the operator rotates the end cover 21 to open the hopper 2 and adds the fruit or nut granules to be mixed into the hopper 2. The stirring mechanism 3 inside the hopper 2 stirs the granules. After stirring, the granules are conveyed through the conveying pipe 22 to the temporary storage box 104 for temporary storage and buffering. Then, the temporary storage box 104 sends them into the inner cavity of the mixing pump 102. At the same time, the ice cream mixture produced by the previous equipment is continuously conveyed to the mixing pump 102 through the feed pipe 101. The mixture and granules are mixed inside the mixing pump 102 to form a uniform ice cream mixture. After mixing, the mixing pump 102 pressurizes and conveys the mixture to the discharge pipe 103. Finally, the mixture is continuously output from the discharge pipe 103 to the next production process, thus realizing the mixing of ice cream mixture and granules.

[0035] Reference Figure 3 and Figure 4 A partition 5 is fixedly installed at the center of the hopper 2. The opposite end faces of the partition 5 and the inner side wall of the hopper 2 respectively enclose the nut area 23 and the fruit area 24. The stirring mechanism 3 includes a first stirring shaft 31 rotatably connected to the nut area 23 and a second stirring shaft 32 rotatably connected to the fruit area 24. Multiple stirring elements 33 are fixedly connected to the outer surfaces of the first stirring shaft 31 and the second stirring shaft 32. The multiple stirring elements 33 are distributed along the length direction of the first stirring shaft 31 or the second stirring shaft 32. It should be noted that in this embodiment, the first stirring shaft 31 and the second stirring shaft 32 are located at the center of the nut area 23 and the fruit area 24 respectively, and the first stirring shaft 31 and the second stirring shaft 32 are not coaxial.

[0036] Reference Figure 3 and Figure 4The partition 5 has an installation cavity 51. The ends of the first stirring shaft 31 and the second stirring shaft 32 both extend into the installation cavity 51 and are connected by a reduction gear set 34. Specifically, the reduction gear set 34 includes a first gear 341 fixedly connected to the end of the first stirring shaft 31 and a second gear 342 fixedly connected to the end of the second stirring shaft 32. The first gear 341 has fewer teeth than the second gear 342 and meshes with the second gear 342, so that the rotation speed of the second stirring shaft 32 is lower than that of the first stirring shaft 31.

[0037] Reference Figure 3 and Figure 4 A drive motor 25 is fixedly installed on the outer surface of the hopper 2. The output shaft of the drive motor 25 extends into the mounting cavity 51 and drives the reduction gear set 34 to rotate through the transmission assembly 35. Specifically, the transmission assembly 35 includes a transmission shaft 351 fixedly connected in the mounting cavity 51. A drive gear 352 that meshes with the first gear 341 is coaxially fixedly connected to the transmission shaft 351. The output shaft of the drive motor 25 and the transmission shaft 351 are connected by a bevel gear set 353.

[0038] When two different materials need to be mixed, the operator adds fruit granules to the fruit granule zone 24 and nut granules to the nut zone 23. During mixing, the drive motor 25 drives the transmission shaft 351 to rotate through the bevel gear set 353. The transmission shaft 351 drives the drive gear 352 to rotate synchronously. The drive gear 352 drives the first gear 341 and the first stirring shaft 31 to rotate through meshing, thereby realizing the mixing operation of the nut zone 23. Since the first gear 341 has fewer teeth than the second gear 342, the two form a reduction gear set 34. When the first gear 341 rotates, it will drive the second gear 342 and the second stirring shaft 32 to rotate at a lower speed than the first stirring shaft 31. In this way, the granular materials in the nut zone 23 and the fruit granule zone 24 are in different mixing speed environments, reducing the possibility of fruit granules breaking, deforming or leaking water due to excessive rotation speed. At the same time, it reduces the possibility of clumping and deposition in the nut zone 23, improving the applicability of the fruit granule mixer.

[0039] Reference Figure 3 and Figure 4 To further improve the applicability of the hopper 2, the ends of the first stirring shaft 31 and the second stirring shaft 32 extending to the mounting cavity 51 are connected by a gear set 36 of the same speed. Specifically, the gear set 36 of the same speed includes a third gear 361 fixedly connected to the end of the first stirring shaft 31, and a fourth gear 362 fixedly connected to the end of the second stirring shaft 32, which meshes with the third gear 361. The parameters of the third gear 361 and the first gear 341 are the same and they can mesh with the drive gear 352. The module of the fourth gear 362 is the same as that of the third gear 361 to achieve the same speed transmission. An adjustment component 6 is provided on the transmission shaft 351 to drive the drive gear 352 to move along the axis of the transmission shaft 351.

[0040] Reference Figure 1 and Figure 4 The drive shaft 351 has an adjustment groove 7 along the axial direction. The adjustment assembly 6 includes an adjustment block 61 that is slidably connected in the adjustment groove 7. The adjustment block 61 is fixedly connected to the inner circumferential surface of the drive gear 352. The adjustment groove 7 has a first electromagnetic block 62 and a second electromagnetic block 63 fixedly connected to the inner sidewalls opposite to each other along the length direction. The adjustment block 61 is made of a ferromagnetic conductive material that is compatible with the first electromagnetic block 62 and the second electromagnetic block 63. The control panel 4 integrates a button 41 for controlling the on / off state of the first electromagnetic block 62 and the second electromagnetic block 63. When the first electromagnetic block 62 is energized and attracts the adjusting block 61, the adjusting block 61 is in the first position, the drive gear 352 meshes with the first gear 341, and the first stirring shaft 31 and the second stirring shaft 32 achieve differential transmission. When the second electromagnetic block 63 is energized and attracts the adjusting block 61, the adjusting block 61 is in the second position, the drive gear 352 meshes with the third gear 361, and the first stirring shaft 31 and the second stirring shaft 32 achieve the same speed transmission.

[0041] When only one ingredient needs to be added to the ice cream mix, the operator presses button 41 to energize the second electromagnetic block 63. The second electromagnetic block 63 attracts the adjusting block 61 and drives it to move along the adjusting groove 7 to the second position. The adjusting block 61 drives the drive gear 352 and the third gear 361 to mesh with each other. At this time, the first stirring shaft 31 and the second stirring shaft 32 rotate at the same speed under the transmission action of the same speed gear set 36. This allows the operator to simultaneously add the same granular material to the nut area 23 and the fruit granule area 24. The space of the dual chamber is fully utilized, increasing the storage capacity of a single material and the stirring efficiency, thereby further improving the applicability of the mixer.

[0042] Reference Figure 5 and Figure 6 The stirring component 33 includes a first stirring blade 331 and a second stirring blade 332 distributed circumferentially along the first stirring shaft 31 or the second stirring shaft 32. In this embodiment, each stirring component 33 includes two first stirring blades 331 and two second stirring blades 332. The first stirring blade 331 is a flexible blade made of food-grade silicone, and the second stirring blade 332 is a rigid blade made of stainless steel. The outer surfaces of the first stirring shaft 31 and the second stirring shaft 32 are both fixed with connecting seats 8 corresponding one-to-one with multiple first stirring blades 331 and second stirring blades 332. An adjusting shaft 81 is rotatably connected to the connecting seat 8. The first stirring blades 331 and the second stirring blades 332 are both fixedly connected to the adjusting shaft 81. A switching component 9 that drives the adjusting shaft 81 to rotate is provided in the nut area 23 and the particle area so that the first stirring blades 331 and the second stirring blades 332 can switch between working state and retracted state. When the first stirring blade 331 or the second stirring blade 332 is in working condition, the length direction of the first stirring blade 331 and the second stirring blade 332 is perpendicular to the axis of the first stirring shaft 31. When the first stirring blade 331 or the second stirring blade 332 is in the retracted state, the length direction of the first stirring blade 331 and the second stirring blade 332 is parallel to the axis direction of the first stirring shaft 31. Reference Figure 5 and Figure 6 The first stirring shaft 31 and the second stirring shaft 32 each have multiple driving cavities 10 inside, and the number of driving cavities 10 corresponds one-to-one with the number of stirring elements 33. The switching assembly 9 includes a switching seat 91 slidably connected inside the driving cavity 10. A guide post 1001 is fixedly connected inside the driving cavity 10, and the switching seat 91 is slidably sleeved on the outer surface of the guide post 1001. The guide post 1001 limits the movement of the switching seat 91 to the axis of the first stirring shaft 31. The first stirring blade 331 and the second stirring blade 332 in the same stirring element 33 are fixedly connected to the switching seat 91. The corresponding toothed belt 92, each adjusting shaft 81 is coaxially fixedly connected to an adjusting gear 93 that meshes with the toothed belt 92, the end of the toothed belt 92 away from the switching seat 91 passes through the first stirring shaft 31 or the second stirring shaft 32 and is fixedly embedded in the tooth gap of the adjusting gear 93, each drive cavity 10 is fixedly connected to a third electromagnetic block 94 on its inner side wall, the switching seat 91 is made of ferromagnetic conductive material adapted to the third electromagnetic block 94, each adjusting shaft 81 is fitted with a torsion spring 95 at both opposite ends, one end of the torsion spring 95 is fixedly connected to the adjusting shaft 81 and the other end is fixedly connected to the connecting seat 8; In its natural state, the first stirring blade 331 is in a retracted state, parallel to the axis of the first stirring shaft 31, while the second stirring blade 332 is in a working state, perpendicular to the axis of the first stirring shaft 31. When the third electromagnetic block 94 is energized, the switching seat 91 drives the adjusting gear 93 to rotate by pulling the toothed belt 92. At this time, the first stirring blade 331 rotates 90° to the working state, and the second stirring blade 332 rotates 90° to the retracted state.

[0043] Before production, workers drive the adjusting shaft 81 to rotate through the switching component 9 according to the characteristics of the material to be stirred. When the adjusting shaft 81 rotates, it drives the first stirring blade 331 and the second stirring blade 332 to switch states synchronously: when processing soft materials such as fruit granules, the switching component 9 controls the first stirring blade 331 to be in the working state and the rigid second stirring blade 332 to be in the retracted state. The low shear characteristics of the flexible blades are used to gently disturb the material, reducing the possibility of fruit granules breaking due to excessive stirring force. When processing hard materials such as nuts, the switching component 9 controls the rigid second stirring blade 332 to be in the working state and the flexible first stirring blade 331 to be in the retracted state. The strong stirring ability of the rigid blade breaks up the nut clumps and prevents sedimentation and bridging. When two materials need to be processed at the same time, they can be adapted separately by the corresponding switching components 9 on the two shafts to achieve differentiated stirring. This allows the worker to quickly adapt to the stirring needs of materials with different characteristics by simply switching components 9, further improving the applicability of the mixer.

[0044] Reference Figure 1 and Figure 6 The control panel 4 is equipped with a button 41 that is electrically connected to the third electromagnetic block 94. It should be noted that in this embodiment, the third electromagnetic blocks 94 in the nut zone 23 and the fruit zone 24 are independent and controlled in separate zones. The button 41 corresponding to different zones can control the on / off state of the third electromagnetic block 94 in that zone independently without interfering with each other, thereby realizing the independent adjustment of the working state of the stirring component 33 in the nut zone 23 and the fruit zone 24.

[0045] When it is necessary to stir the nuts, the worker controls the third electromagnetic block 94 inside the corresponding first stirring shaft 31 or second stirring shaft 32 to be energized by button 41. The magnetic force generated by the third electromagnetic block 94 attracts the switching seat 91 to slide along the drive cavity 10. The switching seat 91 drives the adjusting gear 93 to rotate 90° by pulling the toothed belt 92. At this time, the torsion spring 95 is compressed. The rotation of the adjusting gear 93 drives the adjusting shaft 81 to rotate. The adjusting shaft 81 drives the first stirring blade 331 and the second stirring blade 332 to rotate 90° synchronously. At this time, the first stirring shaft 31 is in the working state and the second stirring blade is in the retracted state, so that the hard first stirring blade 331 participates in stirring the nuts. When it is necessary to stir the fruit granules, the worker controls the third electromagnetic block 94 inside the corresponding first stirring shaft 31 or second stirring shaft 32 to be de-energized via button 41. At this time, the torsion spring 95 resets and drives the adjusting shaft 81 to rotate in the opposite direction. The adjusting shaft 81 drives the adjusting gear 93 to rotate, and the adjusting gear 93 drives the toothed belt 92 to be wound onto the adjusting gear 93. At the same time, under the gravity of the switching seat 91 and the pull of multiple toothed belts 92, it resets. During this process, the first stirring blade 331 resets to the retracted state, and the second stirring blade 332 resets to the working state, so that the soft second stirring blade 332 participates in stirring the fruit granules.

[0046] Reference Figure 6Each drive chamber 10 is rotatably connected to a support gear 1002 corresponding to a plurality of toothed belts 92. The support gear 1002 is meshed with the corresponding toothed belt 92. During the process of the switching seat 91 driving the toothed belt 92 to move, the support gear 1002 provides support and guide limit for the toothed belt 92, and at the same time tensions the toothed belt 92 to reduce the possibility of the toothed belt 92 shaking, deviating or loosening during the transmission process, and ensures smooth operation of the switching process of the first stirring blade 331 and the second stirring blade 332.

[0047] The implementation principle of a pellet mixer according to an embodiment of this application is as follows: When two different materials need to be mixed, the worker first presses the button 41 that controls the power on / off of the third electromagnetic block 94 to adjust the operating state of the stirring component 33. Then, fruit pellets are added to the fruit pellet area 24 and nut pellets are added to the nut pellet area 23. During stirring, the drive motor 25 drives the transmission shaft 351 to rotate through the bevel gear set 353. The transmission shaft 351 drives the drive gear 352 to rotate synchronously. The drive gear 352 drives the first gear 341 and the first stirring shaft 31 to rotate through meshing. To achieve the mixing operation in the nut zone 23, since the number of teeth of the first gear 341 is less than that of the second gear 342, the two form a reduction gear set 34. When the first gear 341 rotates, it will drive the second gear 342 and the second stirring shaft 32 to rotate at a lower speed than the first stirring shaft 31. This allows the granular materials in the nut zone 23 and the fruit granule zone 24 to be in environments with different mixing speeds, reducing the possibility of fruit granules breaking, deforming, or leaking water due to excessive rotation speed. At the same time, it reduces the possibility of clumping and deposition in the nut zone 23, improving the applicability of the fruit granule mixer. When it is necessary to mix the same material, the worker adjusts the operating mode of the regulating component again through the third electromagnetic block 94, and then presses the button 41 that controls the first electromagnetic block 62 or the second electromagnetic block 63 to drive the drive gear 352 to mesh with the third gear 361. At this time, the first stirring shaft 31 and the second stirring shaft 32 rotate at the same speed under the transmission action of the same speed gear set 36. This allows the operator to simultaneously put the same granular material into the nut area 23 and the fruit granule area 24. The space of the dual chamber is fully utilized, increasing the storage capacity of a single material and the mixing efficiency, thereby further improving the applicability of the mixer.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
