Abstract
Description
Technical Field
[0001] The invention relates to the technical field of multi-material quantitative mixing, in particular to a multi-material quantitative mixing device. Background Art
[0002] Quantitative mixing of multiple materials refers to the process of uniformly mixing two or more materials according to the predetermined ratio and precision requirements. In this process, the focus is to ensure that the input amount of each material is accurate and controllable before mixing, so as to obtain a mixed material that meets specific quality standards, and then ensure that it is a qualified mixed material during subsequent packaging or bagging. Therefore, multiple materials need to be quantitatively distributed separately before mixing.
[0003] Traditionally, quantitative distribution before mixing multiple materials is often controlled by using a scale or other quantitative container. After the quantitative distribution, the materials are added and mixed. Especially for products with small single-time usage and many mixing times (such as seasoning packets), the quantitative process of a single material and the mixing process of multiple quantitative materials after quantitative distribution are often carried out on different equipment or structures, resulting in cumbersome operations and low production efficiency. In addition, the quantitative materials may be transported before entering the mixing process due to various external factors, causing loss, affecting quantitative control, and further reducing the quality of the finished products after packaging or bagging.

In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.
[0043] Example 1
[0044] like Figures 1 to 8 Shown
[0045] A multi-material quantitative mixing device, comprising
[0046] A mounting platform 1 is provided with a circular reciprocating conveying mechanism 2 fixedly disposed on the mounting platform 1, and a plurality of mounting bases 31 are evenly disposed on the conveyor belt 21 of the conveyor mechanism 2, and the plurality of mounting bases 31 can make circular reciprocating motion along with the conveyor belt 2, which is a prior art device and will not be described in detail herein; a receiving hopper 3 is mounted on each of the mounting bases 31; preferably, one end of the receiving hopper 3 for dumping materials is in a slope shape, and this scheme facilitates the subsequent dumping of mixed materials and prevents the mixed materials from accumulating on the inside and causing dumping residues.
[0047] Through this solution, the same receiving hopper 3 can receive multiple quantitative materials in sequence to achieve mixing.
[0048] The discharge chute 9 is fixed on the mounting platform 1 through a discharge chute support frame 91, and is used to receive the mixed materials dumped from the plurality of receiving hoppers 3, and facilitates the transportation or subsequent bagging of the mixed materials.
[0049] A feeding mechanism, wherein three feeding mechanisms are provided, and the discharge ports of the three feeding mechanisms are arranged front and back above the upper receiving hopper 3 of the conveying mechanism (2);
[0050] Specifically, the feeding mechanism includes a mounting frame 7, which is enclosed in an "open" shape by four plates. Each mounting frame 7 is provided with a motor 6 and a hopper 5. The motor 6 is vertically arranged inside the mounting frame 7. The power output end of the motor 6 faces vertically upward and is vertically connected with a rotating shaft 55. The other end of the rotating shaft 55 is rotatably installed on the top plate of the mounting frame 7 through a bearing 61 and passes through the outer upper side of the mounting frame 7, and a cylindrical hopper 5 is horizontally fixed thereto; a material pushing plate 52 is arranged inside the hopper 5. The two ends of the material pushing plate 52 abut against the annular side wall of the hopper 5, and the bottom end of the material pushing plate 52 abuts against and is flush with the inner bottom end of the hopper 5;
[0051] Through this solution, all the materials placed in the hopper 5 can be pushed along with the rotation for feeding and scraping off the excess materials.
[0052] Further, the top end of the material pushing plate 52 is fixed to the mounting frame 7 through a baffle mounting frame 8 in the shape of "冖", and the material pushing plate 52 divides the inside of the hopper 5 into a loading area 53 and a feeding area 54. A guide hopper 4 is provided directly below the feeding area 54. The guide hopper 4 is fixed to the mounting frame 7 through a guide hopper support frame 41; a sensor 531 for detecting the remaining amount of materials is arranged in the loading area 53;
[0053] Through this solution, the sensor 531 can be electrically connected to an external feeding device, facilitating real-time automatic replenishment of the loading area 53 to ensure the normal progress of the process.
[0054] Further, four feeding holes 512 are circumferentially arrayed on the bottom annular edge of the hopper 5. A metering tube 51 is fitted into each feeding hole 512 with a transition fit for metering the materials and feeding them downward. The upper end of the metering tube 51 is flush with the bottom surface of the hopper 5. Further, in order to prevent the metering tube 51 from slipping out of the feeding hole 512, a ring-shaped retaining piece 5121 is fixedly provided at the bottom of the feeding hole 512; in addition, an opening and closing assembly 13 is provided at the discharging end of the metering tube 51 for controlling the opening and closing of the four metering tubes 51;
[0055] Through this solution, when the lower end of the metering tube 51 is blocked by a blocking piece 11, it forms a metering container. Coupled with the material pushing plate 52 on the metering tube, the materials can be pushed into the metering tube 51 for feeding and the excess materials piled on it can be scraped off after feeding, thus realizing automatic metering control, replacing the process of workers weighing repeatedly, reducing labor costs; and the fitting method with a transition fit enables the replacement of metering tubes 51 with different pipe diameters, so its capacity can be changed accordingly, and different metering settings can be carried out, with a wider scope of application.
[0056] Specifically, the opening and closing assembly 13 includes a stopper 11 provided on the discharge end of each quantitative tube 51; one end of the stopper 11 is in the shape of a circular plate, and the other end is in the shape of a long strip plate. The end of the stopper 11 in the shape of a circular plate is provided below the discharge end of the quantitative tube 51, so as to facilitate opening or closing the discharge end thereof; a protrusion 101 is provided on the bottom of the end in the shape of a long strip plate, and a bolt 111 is provided on the bottom of the stopper 11 near the first side surface 1011 of the protrusion 101, one end of the bolt 111 is connected to the bottom of the hopper 5 and can swing around the bolt 111, and a spring 112 is provided on the other end of the bolt 111, and the spring 112 abuts against the bottom of the stopper 11, so as to abut the stopper 11 against the bottom of the hopper 5;
[0057] With this solution, a spring 112 is installed on the bolt 111 so that the baffle 11 is not completely fixed, thereby pressing the baffle 11 tightly against the bottom of the material receiving tray 5 so that it will not fall off and cause material leakage, and the baffle 11 can be swung around the bolt 111, so as to facilitate switching the open and closed states of the bottom of the quantitative tube 51.
[0058] Furthermore, a toggle member 10 is provided below the four stoppers 11 for automatically controlling the opening and closing of the four stoppers 11;
[0059] Through this solution, a toggle member 10 can be used in conjunction with multiple baffles 11, thereby achieving the effect of multiple quantitative groups of the same material, which is more efficient and greatly reduces the cost of use.
[0060] Specifically, Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the toggle member 10 includes
[0061] The protrusion 101 provided on each stopper 11,
[0062] Two support seats 103 are arranged below the protrusion 101. The two support seats 103 can be adjusted and fixed on the top plate of the mounting frame 7 through an adjustment fixing mechanism 102. Support rods 104 are vertically fixed on the two support seats 103 respectively. Threaded columns 1042 are provided at the upper and lower ends of the two support rods 1041. The threaded columns 1042 at the lower ends are passed through the support seats 103 and fixed by nuts 1041. The threaded columns 1042 at the upper ends of the two support rods 104 are respectively transversely passed through expenditure blocks 105 and are also fixed by nuts 1041. The far ends of the two expenditure blocks 105 are respectively provided with toggle wheels 106 for reciprocatingly toggling the protrusion 101; preferably, the toggle wheel 106 is arranged directly below the unloading area 54;
[0063] Through this solution, it is ensured that the opening and closing of the blocking member 11 occurs at the material discharge area 54, thereby ensuring that the material will not spill out.
[0064] Furthermore, the two expenditure blocks 105 are respectively a first expenditure block 1051 and a second expenditure block 1052, and the two toggle wheels 106 are respectively a first toggle wheel 1061 and a second toggle wheel 1062; the first toggle wheel 1061 is arranged on the motion path of the left side of the protrusion 101, and the second toggle wheel 1062 is arranged on the motion path of the bottom surface of the protrusion 101;
[0065] Through this scheme, it is ensured that the two toggle wheels 106 can produce a collision with the protrusion 101 in accordance with mechanical principles on the circular motion path of the protrusion 101, so that when used together, they form a mechanical switch valve structure that does not require a spring and causes the blocker 11 to swing back and forth, thereby realizing the opening and closing functions through two collisions, with a longer service life and more stable use. Moreover, by setting the threaded column 1042 and the nut 1041, an adjustable function can be achieved, which facilitates the adjustment of the angle between the two expenditure blocks 105, and then adjusts the position of the toggle wheel 106 to place it on a suitable motion path.
[0066] Furthermore, the adjustment and fixing mechanism 102 includes a fixing sleeve 1021 inserted on the outside of the rotating shaft 55, and the fixing sleeve 1021 is fixed on the mounting frame 7; a clamping hoop 1022 is sleeved on the outside of the fixing sleeve 1021, and both the supporting seats 103 are fixed on the clamping hoop 1022. Through this solution, the height of the supporting seat 103 can be easily adjusted, and then the height of the toggle wheel 106 can be adjusted to prevent it from hitting the stopper 11 and causing it to be unable to be used normally.
[0067] Example 2
[0068] The structure is the same as that of Example 1, except that: the three motors 6 are all servo motors, and the motors 6 are electrically connected to the conveyor belt 2, and each motor 6 and the conveyor belt 2 are in step, that is, the motor 6 rotates 90 degrees to produce a pace pause, and the pause causes the hopper 3 in the unloading area 54 on the conveyor belt 2 to complete one material receiving and switch to the next hopper 3 to prepare for material receiving.
[0069] This solution improves the continuity of the overall operation and improves the work efficiency.
[0070] The working mode of this device:
[0071] Before use, as needed, a quantitative tube 51 with a suitable capacity is loaded into the feeding hole 512, and then the three materials are respectively put into the loading areas 53 of the three hoppers 5, and then the conveying mechanism 2 and the motor 6 located at the head end of the conveying direction are started first, and the entire hopper 5 rotates with the rotation of the motor 6. When the hopper 5 rotates, the baffle 11 located at the bottom thereof also makes a circular motion. At this time, the hopper 5 and the material push plate 52 also rotate relative to each other, so that the material located in the loading area 53 is rotated and pushed. When the material falls on the quantitative tube 51, the empty measuring hole 511 of the quantitative tube 51 receives part of the material and is filled, and when the material push plate 52 rotates from above it, it scrapes away the excess material to make it just filled, thereby realizing quantitative control; when the quantitative tube 51 filled with quantitative material moves to the first dial located below the unloading area 54 along with the corresponding baffle 11 below it, When the first driving wheel 1061 is at the position of the moving wheel 1061, the first driving wheel 1061 lightly hits the first side surface 1011 of the protrusion 101, causing the protrusion 101 to swing, and then its second side surface 1022 is also tilted compared to the initial position. The swinging protrusion 101 drives the blocking member 11 to swing to one side around the bolt 111, so that the circular plate-shaped end of the blocking member 11 moves away from the discharge end of the metering tube 51 to one side, thereby opening the metering tube 51, and a certain amount of material leaks out of the metering tube 51, and the leaked material falls into the receiving hopper 3 on the conveying mechanism 2 along with the guide hopper 4. At this time, when the second side surface 1022 of the protrusion 101 after being hit lightly hits the second driving wheel 1062, the inclined second side surface 1022 is knocked back to the initial position, and then the blocking member 11 returns to the initial position (that is, the discharge end of the metering tube 51 is kept closed) in preparation for the next quantitative loading of materials and the cycle operation in sequence.
[0072] The material initially leaked from the hopper 5 at the head end falls into the receiving hopper 3 on the conveying mechanism 2 along with the guide hopper 4 and is then transferred. Then, when the receiving hopper 3 with one material passes under the subsequent hopper 5, the corresponding motor 6 is started, and the receiving hopper 3 with one material similarly receives a certain amount of other materials from other hoppers 5 to achieve mixing into a mixed material. After the mixed material is transferred to the end along with the conveying mechanism 2, the mixed material is dumped out for cyclic material collection, and the dumped mixed material falls into the discharge trough 9 for discharge.
[0073] After the quantitative mixing of the multiple materials is completed, the motor 6 and the conveying mechanism 2 can be turned off in sequence.
[0074] The above-mentioned embodiments only express the specific implementation of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
