[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] When using existing granule packaging machines, workers place the products that need to be pre-packaged into the machine for packaging. However, in some less developed areas, other equipment may be needed to weigh the pre-packaged products before packaging them into granules. This process requires the use of multiple devices, is very cumbersome, and greatly reduces the efficiency of the granule packaging machine.

[0025] In view of this, the present invention provides a precise quantitative feeding structure for a granule packaging machine, which solves the problem that when using existing granule packaging machines, the operator places the products to be pre-packaged into the granule packaging machine for packaging. However, in some backward areas, other equipment may be needed to quantitatively weigh the pre-packaged products before packaging them through the granule packaging machine. This process requires the use of multiple devices, which is very cumbersome and greatly reduces the working efficiency of the granule packaging machine.

[0026] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0027] Example 1: By Figure 1-5As can be seen, a precise quantitative feeding structure for a granule packaging machine includes a feeding box 1, a feeding port 11 is provided on one side of the inner wall of the feeding box 1, a distributing box 2 is provided below the feeding box 1, and through slots 21 are provided on both sides of the distributing box 2. The precise quantitative feeding structure for the granule packaging machine also includes a quantitative device 3, a feeding device 4, and a conveying device 5. The quantitative device 3 is located inside the distributing box 2; the feeding device 4 is located inside the feeding port 11; and the conveying device 5 is located below the distributing box 2. The quantitative device 3 quantitatively processes the product inside the feeding box 1, the feeding device 4 replenishes the quantitatively processed product, and the conveying device 5 conveys the product obtained through the distributing box 2 to the next working device.

[0028] In the specific implementation process, it is worth noting that the upper part of the feeding box 1 is a quadrangular prism, the lower cross section is a trapezoid, and the bottom has a discharge port. The replenishment port 11 is located on one side and is rectangular. It works with the replenishment device 4 to provide a channel for subsequent replenishment operations. The bottom of the distribution box 2 also has a discharge port, and the two sides have through grooves 21. The through grooves 21 work with the quantitative device 3 to realize the quantitative measurement of the product. The conveying device 5 can transport the quantitative product to the next work. Through the cooperation of the quantitative device 3, the replenishment device 4 and the conveying device 5, the ease of use of the granule packaging machine is greatly improved.

[0029] Furthermore, a support rod 12 is fixedly connected to the inner wall of the feed box 1. The support rod 12 is rotatably connected to the protective box 13 via a sealed bearing. The metering device 3 includes an electric telescopic rod 31, a connecting rod 32, a first blocking block 33, a second blocking block 34, a weighing basin 35, a discharge port 36, a limiting plate 37, and a weighing sensor 38. The electric telescopic rod 31 is located inside the protective box 13. The connecting rod 32 is fixedly connected to the output end of the electric telescopic rod 31, passes through the bottom of the protective box 13 and the feed box 1 in sequence, and extends into the interior of the dispensing box 2. The first blocking block 33 is fixedly connected to the outer wall of the connecting rod 32 and inserted into the bottom of the feed box 1. The second blocking block... 34 is fixedly connected to the outer wall of the connecting rod 32 and inserted into the bottom of the distribution box 2; the weighing basin 35 is set inside the distribution box 2; the discharge port 36 is opened at the bottom of the weighing basin 35; two limiting plates 37 are provided, respectively fixedly connected to both sides of the weighing basin 35 and respectively inserted into the inner wall of the two through slots 21; two weighing sensors 38 are provided, respectively installed at the bottom of the inner wall of the through slot 21 and attached to the bottom of the limiting plate 37; wherein, the electric telescopic rod 31 drives the connecting rod 32 to move, and through the cooperation of the first blocking block 33, the second blocking block 34, the weighing basin 35, the limiting plate 37 and the weighing sensor 38, quantitative operation of the product is realized;

[0030] In the specific implementation process, it is worth noting that the support rod 12 consists of a bearing and two crossbars. The crossbars are fixedly connected to both sides of the bearing, and the inner wall of the bearing is fixedly connected to the outer wall of the protective box 13, providing support for the protective box 13. The top of the protective box 13 is fixedly connected to a sealing cover by four bolts, which protects the electric telescopic rod 31 inside the protective box 13. The model of the electric telescopic rod 31 is selected according to actual needs, as long as it meets the working requirements. The connecting rod 32 fixes the first blocking block 33 and the second blocking block 34 together with the output end of the electric telescopic rod 31. The bottom of the first blocking block 33 is a quadrangular prism and the top is a cone. The overall shape of the second blocking block 34 is... Similar to the first barrier block 33, but larger in volume, the weighing basin 35 has a trapezoidal cross-section with a square bottom and a circular discharge port 36 in the middle. The limiting plates 37 fixedly connected on both sides have an L-shaped cross-section. The symmetrical basin 35 serves as a lateral limiting device, and the bottom is attached to the weighing sensor 38. The model of the weighing sensor 38 can be selected according to actual needs. Through the cooperation of the electric telescopic rod 31, connecting rod 32, first barrier block 33, second barrier block 34, weighing basin 35, discharge port 36, limiting plate 37 and weighing sensor 38, quantitative feeding of pre-packaged products is realized, which improves the ease of use of the precise quantitative feeding structure of the granule packaging machine.

[0031] Furthermore, the replenishing device 4 includes a second servo motor 41, a transmission rod 42, a replenishing cylinder 43, and a replenishing trough 44. The second servo motor 41 is located outside the feeding box 1 and on one side of the replenishing port 11. The transmission rod 42 is fixedly connected to the output end of the second servo motor 41 and rotatably connected to the inner wall of the replenishing port 11 through a sealed bearing. The replenishing cylinder 43 is fixedly connected to the outer wall of the transmission rod 42. The replenishing trough 44 is opened on the outer wall of the replenishing cylinder 43. The second servo motor 41 drives the transmission rod 42 to rotate, and through the cooperation of the replenishing cylinder 43 and the replenishing trough 44, replenishes the products inside the dispensing box 2.

[0032] In the specific implementation process, it is worth noting that the model of the second servo motor 41 is selected according to actual needs, as long as it meets the working requirements. The feeding cylinder 43 is cylindrical in shape and installed horizontally. The surface is provided with feeding grooves 44, and there are four feeding grooves 44. The granular products are placed inside them. Through the cooperation of the second servo motor 41, the transmission rod 42 and the feeding cylinder 43, products that have not reached the quantitative standard are replenished, thereby improving the quantitative accuracy of the precise quantitative feeding structure of the granule packaging machine.

[0033] Specifically, in the initial state, the first blocking block 33 and the second blocking block 34 respectively seal the discharge ports at the bottom of the feeding box 1 and the distributing box 2. First, the operator connects the external power supply to the controller 7 and starts the controller 7. The operator then connects the external power supply to the electric telescopic rod 31 through the controller 7 and starts the electric telescopic rod 31, causing the output end of the electric telescopic rod 31 in the initial state to extend, driving the connecting rod 32 to move downwards, causing the first blocking block 33 and the second blocking block 34 to move downwards until the first blocking block 33 and the second blocking block 34 block the discharge ports at the bottom of the feeding box 1 and the distributing box 2, stopping the operation of the electric telescopic rod 31. After this, granular products can be poured into the interior of the feeding box 1. When it is necessary to use the granule packaging machine for fine packaging... When the metered feeding structure is in operation, the operator activates the electric telescopic rod 31. At this time, the output end of the electric telescopic rod 31, which is in an extended state, shortens, causing the connecting rod 32 to move upwards. The connecting rod 32 then moves the first blocking block 33 and the second blocking block 34 upwards, opening the outlet of the feeding box 1. The granular product falls from the bottom outlet of the feeding box 1 into the weighing basin 35. The weighing basin 35 moves downwards under the influence of the granular product's weight, causing the limit plates 37 on both sides to move downwards. The limit plates 37 press against the signal collection end of the weighing sensor 38, which transmits the signal to an external signal receiver. By observing the signal received by the signal receiver, the operator can monitor whether the weight of the granular product has reached the target weight. When the target weight is reached... When the weight is set, the electric telescopic rod 31 extends, and the connecting rod 32 drives the first blocking block 33 and the second blocking block 34 to move downwards again, closing the outlet of the feeding box 1 again. At this time, the discharge port 36 opens, and the granular product enters the bottom of the distributing box 2 through the discharge port 36. At this time, the electric telescopic rod 31 begins to shorten, starting the second quantitative operation. During the process of the second blocking block 34 rising, the outlet at the bottom of the distributing box 2 opens, and the granular product falls from the inside of the distributing box 2 into the feeding trough 55, and proceeds to the next operation through the feeding trough 55. It can be understood that during the weighing process, the value transmitted back by the weighing sensor 38 is different from the actual weight of the granular product. This is due to the precise quantitative feeding structure of the granule packaging machine. Previously, it was necessary to add pressure to the top of the second barrier block 34. This could be done by adding a weighing sensor 38 to the top of the second barrier block 34, or by adjusting the device before use based on the actual quality of the granular product until it met the requirements. If it was found that the quantitative device 3 was not accurate enough after long-term use, the operator could connect the external power supply of the second servo motor 41 through the controller 7 to start the second servo motor 41. The second servo motor 41 would drive the transmission rod 42 to rotate, and the transmission rod 42 would drive the feeding cylinder 43 to rotate. The feeding cylinder 43 contained a fixed amount of granular product. The feeding cylinder 43 would drive the feeding trough 44 to rotate, and the granular product inside the feeding trough 44 would fall from the feeding port 11 into the weighing basin 35, thus realizing the feeding operation.

[0034] Example 2: From Figure 1-5 It is known that a base plate 8 is provided below the material distribution box 2. The conveying device 5 includes a third servo motor 51, idler rollers 52, a conveyor belt 53, a support plate 54, and a feeding trough 55. The third servo motor 51 is fixedly connected to the top of the base plate 8 through a motor mount. There are two idler rollers 52, one of which is located between the material distribution box 2 and the base plate 8, and the other is located on the side of the base plate 8 away from the material distribution box 2, with one end installed at the output end of the third servo motor 51. The conveyor belt 53 is installed on the outer wall of the two idler rollers 52. There are four support plates 54, which are rotatably connected to the two ends of the two idler rollers 52 through sealed bearings. The feeding trough 55 is located on the top of the conveyor belt 53. The third servo motor 51 drives one idler roller 52 to rotate, and through the cooperation of the two idler rollers 52 and the conveyor belt 53, the feeding trough 55 moves to the next working location.

[0035] In the specific implementation process, it is worth noting that the base plate 8 plays a supporting role for the various components on its top, and the base plate 8 extends a portion on the side near the third servo motor 51 to facilitate the fixing of the third servo motor 51. The models of the third servo motor 51, idler roller 52 and conveyor belt 53 are selected according to actual needs, as long as they meet the requirements. It is understood that the number of idler rollers 52 and the length of conveyor belt 53 can be selected and purchased according to actual needs, as long as they meet the requirements. The support plate 54 plays a supporting role for the idler rollers 52 and conveyor belt 53, which greatly improves the practicality of the precise quantitative feeding structure of the granule packaging machine.

[0036] Furthermore, a stirring rod 132 is fixedly connected to the lower outer wall of the protective box 13, and a connecting column 133 is rotatably connected to the top of the inner wall of the protective box 13 through a sealed bearing. The bottom of the connecting column 133 is fixedly connected to the top of the electric telescopic rod 31. A first servo motor 131 is provided above the connecting column 133. The first servo motor 131 is fixedly connected to the top of the feed box 1 through a motor bracket, and the output end of the first servo motor 131 is fixedly connected to the top of the protective box 13.

[0037] In the specific implementation process, it is worth noting that there are four stirring rods 132. The total length of two stirring rods 132 plus the diameter of the protective box 13 is less than the minimum distance between the two sides of the inner wall of the feed box 1. This ensures that the stirring rods 132 will not contact the inner wall of the feed box 1 when they rotate. When the protective box 13 rotates, the electric telescopic rod 31 is kept stationary by the cooperation of the connecting column 133, the first blocking block 33 and the second blocking block 34. The model of the first servo motor 131 is selected according to actual needs to meet the working requirements. This improves the working stability of the precise quantitative feeding structure of the granule packaging machine.

[0038] Furthermore, the outer walls of the feed box 1 and the distribution box 2 are both fixedly connected with connecting plates 6, and the four corners of the two connecting plates 6 are fixedly connected with support columns 61. The bottom of the support columns 61 is fixedly connected to the top of the base plate 8, and the four bottom corners of the base plate 8 are equipped with support feet 9.

[0039] In the specific implementation process, it is worth noting that the connecting plate 6 is in the positive direction and has a through hole in the middle, which facilitates the fixed connection to the outer wall of the feeding box 1 and the distributing box 2. There are four support columns 61, which support the feeding box 1 and the distributing box 2 through the connecting plate 6. The support feet 9 support the overall precise quantitative feeding structure of the granule packaging machine. Furthermore, the support feet 9 can be raised or lowered according to actual needs, thus ensuring the stability of the precise quantitative feeding structure of the granule packaging machine.

[0040] Furthermore, a controller 7 is provided on the front of the material distribution box 2, and the controller 7 is installed on the outer wall of the connecting plate 6;

[0041] In the specific implementation process, it is worth noting that the model of controller 7 can be selected according to actual needs, as long as it meets the requirements of the operation. Operators can use controller 7 to preset the quantitative value of the product, control the start and stop of each motor, and adjust the feeding and conveying speed, thereby improving the automation level of the precise quantitative feeding structure of the granule packaging machine.

[0042] Furthermore, a guide plate 321 is provided between the first barrier block 33 and the second barrier block 34, and the inner wall of the guide plate 321 is fixedly connected to the outer wall of the connecting rod 32.

[0043] In the specific implementation process, it is worth noting that the guide plate 321 can effectively guide the flow of materials, so that the materials fall into the weighing basin 35 more smoothly, and prevent the granular products from leaking directly to the outside of the device through the gap when the first barrier block 33 and the second barrier block 34 move, thereby improving the working stability of the precise quantitative feeding structure of the granule packaging machine.

[0044] Specifically, firstly, the controller 7 connects to the external power supply of the first servo motor 131, starting the first servo motor 131. The first servo motor 131 drives the protective box 13 to rotate, and the protective box 13 drives the stirring rod 132 to rotate. When the material feeding is slow, this part of the structure is activated to speed up the feeding speed of the feeding box 1. Secondly, the controller 7 connects to the external power supply of the third servo motor 51, starting the third servo motor 51. The third servo motor 51 drives a roller 52 to rotate. Through the cooperation of the two rollers 52 and the conveyor belt 53, the conveyor belt 53 is made to rotate in a cycle. The metered material falls from the discharge port at the bottom of the distribution box 2. The material enters the feeding trough 55, which moves to the next working location as the conveyor belt 53 rotates, conveying the material there. This improves the automation level of the precise quantitative feeding structure of the granule packaging machine. Furthermore, the guide plate 321 effectively guides the material flow, allowing the material to fall more smoothly into the weighing basin 35, and prevents the granule product from leaking directly to the outside of the device through the gap when the first barrier block 33 and the second barrier block 34 move. This improves the working stability of the precise quantitative feeding structure of the granule packaging machine. Finally, the stability of the precise quantitative feeding structure of the granule packaging machine is ensured by the cooperation of the connecting plate 6, the support column 61, and the support foot 9.
