Description
Technical Field
[0001] The utility model relates to the technical field of weighing equipment, and particularly relates to a metering device for prefabricated vegetable production. Background Art
[0002] Prefabricated vegetables are convenient dishes that use modern standardized assembly-line operations to package the processed dishes after hygienically and scientifically processing the dish raw materials. When needed, they can be directly eaten after a simple heating step. Since there are many categories of prefabricated vegetable products and a large variety of selected ingredients, generally speaking, when making ratios, special attention needs to be paid to the weight combination of various ingredient raw materials. Once the weight addition of a certain ingredient does not reach the preset weight or exceeds the preset weight, the tastes of the prefabricated vegetable dishes will vary, affecting the quality promotion of prefabricated vegetables.
[0003] Currently, in the actual operation process of personnel producing prefabricated vegetables and making ratios, usually, manual measuring tools are used to pre-quantify the ingredient raw materials to be fed, and then the pre-quantified ingredient raw materials are sent into the feeding equipment and then transmitted to the processing equipment. Although this manual manual ratio metering method is effective, in the case of long-term production operations, it is easy for workers to get tired and neglect the metering values, resulting in uneven batching. At the same time, the time consumed for pre-mixing ingredients in this way is relatively long, the process is rather cumbersome, increasing the workload of workers and leading to low work efficiency. Summary of the Utility Model
[0004] In view of this, the purpose of the utility model is to provide a metering device for prefabricated vegetable production to solve the problems that it is difficult to accurately control the metering value when manually using measuring tools to measure ingredient raw materials in advance and the work efficiency is low.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A metering device for prefabricated vegetable production includes a feeding hopper, an upper baffle, a lower baffle, a transmission mechanism, a reset mechanism, and a limiting mechanism. The upper baffle and the lower baffle are both rotatably arranged up and down inside the small end of the feeding hopper to open and close the feeding hopper; the lower baffle is arranged below the upper baffle and is connected to the upper baffle through the transmission mechanism, so that the upper baffle and the lower baffle can alternately close the feeding hopper; a weighing sensor is arranged below the upper surface layer of the lower baffle, and the bottom of the lower baffle is connected to the feeding hopper through the reset mechanism. The reset mechanism can rotate the lower baffle upward to restore the lower baffle to the state of closing the feeding hopper; the limiting mechanism is arranged on the feeding hopper and is electrically connected to the weighing sensor. The limiting mechanism can limit the downward rotation of the lower baffle according to whether the threshold value set by the weighing sensor is reached.
[0007] As an alternative solution, the reset mechanism is a spring rotating shaft, and the lower baffle is rotatably connected to the inner side wall of the hopper through the spring rotating shaft.
[0008] As an alternative solution, the reset mechanism includes a connecting rod, a slider, a chute and a first compression spring; both ends of the connecting rod are respectively connected to the lower baffle and the slider; the slider is slidably connected up and down in the chute, the chute is vertically fixedly connected to the side wall of the hopper, and the slider is connected to the bottom wall of the chute through the first compression spring.
[0009] As an alternative solution, a positioning rod is provided in the chute, and the positioning rod penetrates through the slider and extends into the first compression spring.
[0010] As an alternative solution, the transmission mechanism includes a driving pulley, a driven pulley and a belt; the driving pulley is coaxially connected to the rotating shaft of the lower baffle, and the driven pulley is coaxially connected to the rotating shaft of the upper baffle; the belt connects the driving pulley and the driven pulley; the upper baffle and the lower baffle are respectively rotatably connected to the opposite inner side walls of the hopper.
[0011] As an alternative solution, the limiting mechanism includes a housing, a clamping strip, an electromagnet and a second compression spring; the housing is fixedly connected to the outer side wall of the hopper; one end of the clamping strip penetrates and extends into the hopper, and the upper surface of the end of the clamping strip extending into the hopper can abut against the lower surface of the free end of the lower baffle, and a chamfer is provided at the edge of the lower surface of the end of the clamping strip extending into the hopper; the electromagnet is arranged in the housing and is electrically connected to the weighing sensor; both ends of the second compression spring are respectively connected to the electromagnet and the clamping strip.
[0012] Due to the adoption of the above technical solutions, the present utility model will have the following beneficial effects:
[0013] 1. By arranging the lower baffle below the upper baffle and connecting the upper baffle through the transmission mechanism, the upper baffle and the lower baffle can alternately close the hopper, and the food raw materials falling from the large end of the hopper accumulate on the upper baffle or the lower baffle. When the metered food raw materials slide off the lower baffle for collection, the upper baffle is in the state of closing the hopper, which can prevent the food raw materials falling from the large end of the hopper from falling onto the collection device, thereby reducing the measurement error caused.
[0014] 2. By arranging a weighing sensor under the upper surface layer of the lower baffle, when the weight of the food raw materials accumulated on the lower baffle reaches the threshold value set by the weighing sensor, the weighing sensor sends an electrical signal to the limiting mechanism, and the limiting mechanism releases the restriction on the lower baffle, enabling the lower baffle to rotate downward under the action of the gravity of the food raw materials and its own gravity to open the feeding hopper. As a result, the food raw materials can slide down from the lower baffle. After the gravity borne by the reset mechanism is reduced, the lower baffle can be rotated upward until the lower baffle is restored to the state of closing the feeding hopper to receive the food raw materials to be measured again.
[0015] Compared with the prior art that requires manual pre-measurement of food ingredients using measuring tools, the utility model can stably and accurately measure food ingredients during the production process, without manual operation and with high work efficiency.

[0026] Please refer to Figures 1-4 , in an embodiment of a metering device for prefabricated food production of the present utility model, the metering device for prefabricated food production includes a feeding hopper 1, an upper baffle 2, a lower baffle 3, a transmission mechanism 4, a reset mechanism 5 and a limiting mechanism 6;
[0027] Among them, the feeding hopper 1 is in the shape of a square funnel. The large end of the feeding hopper 1 is used to receive the food raw materials to be metered. The upper baffle 2 and the lower baffle 3 are both rotatably arranged up and down inside the small end of the feeding hopper 1. The upper baffle 2 and the lower baffle 3 are adapted to the shape and size of the caliber of the small end of the feeding hopper 1, so that the feeding hopper 1 can be opened and closed by rotating the upper baffle 2 and the lower baffle 3; the lower baffle 3 is arranged below the upper baffle 2 and is connected to the upper baffle 2 through the transmission mechanism 4, so that the upper baffle 2 and the lower baffle 3 can alternately close the feeding hopper 1, and the food raw materials falling from the large end of the feeding hopper 1 accumulate on the upper baffle 2 or the lower baffle 3.
[0028] Among them, a weighing sensor 31 is provided under the upper surface of the lower baffle 3. The weighing sensor 31 is an existing device for measuring the weight of an object. In this embodiment, it is used to measure the weight of the food raw materials on the lower baffle 3. Specifically, when the food raw materials apply weight to the lower baffle 3, the material inside the sensor will undergo a slight deformation, and this deformation will cause a change in resistance. By measuring the change in resistance, the applied weight can be calculated.
[0029] Among them, the bottom of the lower baffle 3 is connected to the feeding hopper 1 through a reset mechanism 5. The reset mechanism 5 can rotate the lower baffle 3 upward to restore the lower baffle 3 to the state of closing the feeding hopper 1; a limiting mechanism 6 is arranged on the feeding hopper 1 and is electrically connected to the weighing sensor 31. The limiting mechanism 6 can limit the downward rotation of the lower baffle 3 according to whether the threshold value set by the weighing sensor 31 is reached. When the weight of the food raw materials accumulated on the lower baffle 3 reaches the threshold value set by the weighing sensor 31, the weighing sensor 31 sends an electrical signal to the limiting mechanism 6, and the limiting mechanism 6 releases the restriction on the lower baffle 3, so that the lower baffle 3 rotates downward under the action of the gravity of the food raw materials and the gravity of the lower baffle 3 itself to open the feeding hopper 1, and then the food raw materials can fall from the lower baffle 3. In this way, after the gravity borne by the reset mechanism 5 is reduced, the reset mechanism 5 can rotate the lower baffle 3 upward until the lower baffle 3 is restored to the state of closing the feeding hopper 1.
[0030] Specifically, the reset mechanism 5 can be set to include a connecting rod 51, a slider 52, a sliding groove 53 and a first compression spring 54; both ends of the connecting rod 51 are respectively connected to the lower baffle 3 and the slider 52; the slider 52 is slidably connected up and down in the sliding groove 53, the sliding groove 53 is vertically and fixedly connected to the side wall of the feeding hopper 1, and the slider 52 is connected to the bottom wall of the sliding groove 53 through the first compression spring 54. When the lower baffle 3 rotates downward, it can drive the slider 52 to compress the first compression spring 54 downward along the sliding groove 53. After the limiting mechanism 6 releases the restriction on the lower baffle 3, the elastic force provided by the first compression spring 54 is less than the gravity of the food raw materials and the lower baffle 3, so that the lower baffle 3 can rotate downward; when the lower baffle 3 rotates until the food raw materials completely slide off, the upper baffle 2 accumulating the food raw materials can generate a transmission force on the lower baffle 3 through the transmission mechanism 4, and this transmission force cooperates with the elastic force of the first compression spring 54 just to overcome the gravity of the lower baffle 3, so that the lower baffle 3 rotates upward to restore its original state.
[0031] Furthermore, a vertical positioning rod 55 can be arranged in the sliding groove 53. The positioning rod 55 passes through the slider 52 and extends into the first compression spring 54. Both ends of the positioning rod 55 are respectively fixedly connected to the top wall and the bottom wall of the sliding groove 53. The positioning rod 55 can guide the slider 52 and prevent the first compression spring 54 from bending.
[0032] Specifically, the transmission mechanism 4 includes a driving pulley 41, a driven pulley 42 and a belt 43; the driving pulley 41 is coaxially connected to the rotating shaft of the lower baffle 3, the driven pulley 42 is coaxially connected to the rotating shaft of the upper baffle 2, and the diameter of the driving pulley 41 is larger than that of the driven pulley 42; the belt 43 connects the driving pulley 41 and the driven pulley 42; the upper baffle 2 and the lower baffle 3 are respectively rotatably connected to the opposite inner side walls of the hopper 1. When the lower baffle 3 rotates downward to open the hopper 1, the lower baffle 3 drives the driving pulley 41 to rotate, the driving pulley 41 drives the driven pulley 42 to rotate synchronously through the belt 43, and the driven pulley 42 drives the upper baffle 2 to rotate upward to close the hopper 1.
[0033] Please refer to Figure 5 , in this embodiment, the limiting mechanism 6 includes a housing 61, a clamping strip 62, an electromagnet 63 and a second compression spring 64; the housing 61 is fixedly connected to the outer side wall of the hopper 1; one end of the clamping strip 62 penetrates into the hopper 1, and the upper surface of the end of the clamping strip 62 extending into the hopper 1 can abut against the lower surface of the free end of the lower baffle 3, and a chamfer is provided at the edge of the lower surface of the end of the clamping strip 62 extending into the hopper 1; the electromagnet 63 is arranged in the housing 61 and is electrically connected to the weighing sensor 31; both ends of the second compression spring 64 are respectively connected to the electromagnet 63 and the clamping strip 62; when the weight of the food raw materials accumulated on the lower baffle 3 reaches the threshold value set by the weighing sensor 31, the weighing sensor 31 sends an electrical signal to energize the electromagnet 63, and after the electromagnet 63 is energized, it attracts the clamping strip 62 to contract back into the housing 61, so that the lower baffle 3 loses the restriction of the clamping strip 62 and can rotate downward; after the food raw materials slide down, the value measured by the weighing sensor 31 is lower than the set threshold value, which causes the electromagnet 63 to be de-energized, so that the clamping strip 62 returns to its original state under the action of the elastic force of the second compression spring 64; when the lower baffle 3 rotates upward to reset, the lower baffle 3 presses the clamping strip 62 and rotates upward along the chamfer at the end of the clamping strip 62 until the clamping strip 62 is no longer pressed and pops out again to abut against the lower surface of the lower baffle 3.
[0034] In another embodiment, the reset mechanism 5 can be set as a spring rotating shaft, and the lower baffle 3 is rotatably connected to the inner side wall of the hopper 1 through the spring rotating shaft, and the spring rotating shaft provides the elastic force for rotating the lower baffle 3 upward to restore the lower baffle 3 to its original state. The spring rotating shaft is an existing component that combines the functions of a spring and a rotating shaft. It integrates a spring on a shaft and is usually used to provide rotational resistance or elastic support.
[0035] The usage method or working principle of the present utility model is as follows:
[0036] The conveyed food raw materials fall from the large end of the hopper 1 onto the lower baffle 3. When the food raw materials accumulated on the lower baffle 3 reach the threshold set by the weighing sensor 31, the weighing sensor 31 sends an electrical signal to energize the electromagnet 63. After the electromagnet 63 is energized, it attracts the latch 62 to retract into the housing 61, causing the lower baffle 3 to lose the restriction of the latch 62. Since the elastic force provided by the first compression spring 54 is less than the gravity of the food raw materials and the lower baffle 3, the lower baffle 3 can rotate downward.
[0037] When the lower baffle 3 rotates downward to open the hopper 1, the metered food raw materials slide down along the lower baffle 3. After the food raw materials slide down, the value measured by the weighing sensor 31 is lower than the set threshold, causing the electromagnet 63 to lose power, so that the latch 62 returns to its original state under the elastic force of the second compression spring 64; the fallen food raw materials are collected by the collecting device at the small end opening of the hopper 1. At the same time, the lower baffle 3 drives the driving pulley 41 to rotate, and the driving pulley 41 drives the driven pulley 42 to rotate synchronously through the belt 43. The driven pulley 42 drives the upper baffle 2 to rotate upward to close the hopper 1, preventing the food raw materials falling from the large end of the hopper 1 from falling onto the collecting device to reduce the measurement error caused.
[0038] After all the food raw materials on the lower baffle 3 have completely slid down, the upper baffle 2 accumulating the food raw materials generates a driving force on the lower baffle 3 through the transmission mechanism 4. This driving force, combined with the elastic force of the first compression spring 54, can just overcome the gravity of the lower baffle 3, causing the lower baffle 3 to rotate upward; when it rotates to the limiting mechanism 6, the lower baffle 3 squeezes the latch 62 and rotates upward along the chamfer at the end of the latch 62 until the latch 62 is no longer squeezed and pops out again to abut against the lower surface of the lower baffle 3, and the lower baffle 3 completes the reset.
[0039] The above embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
