Description

Technical Field

[0001] The present invention relates to the technical field of douchi filling, and particularly relates to an automatic filling device for douchi sauce. Background Art

[0002] Douchi sauce is rich in nutrition and has a wide variety of categories. It is often used as a condiment and is widely welcomed by consumers. During the production and filling of stir-fried fragrant douchi, since douchi sauce is an oil mixture and the flow rates of the oils are different, automatic filling has always been a difficult problem in the industry.

[0003] The existing filling methods include cold filling method and hot filling method. The cold filling method is a normal temperature filling method, mainly relative to the high temperature filling method. It is mainly for liquids or sauces with relatively small particles, good fluidity, and low particle hardness. Its working principle is mainly to keep the particles evenly suspended through a stirring or pumping system to achieve sauce filling; the hot filling method is mainly used for filling sauces containing particulate matter. It is a technology that ensures product sterility and extends the shelf life by filling at high temperature and quickly sealing. It also keeps the particles evenly suspended through a stirring or pumping system to achieve filling. However, this filling method has requirements for the fluidity and size of the particulate matter. It is mainly for sauces with good fluidity, no oil, and particle size within 2 mm. Sauces with oil, poor fluidity, viscosity, and particles larger than 2 mm are likely to cause blockage of the conveying pipeline or nozzle, making it difficult to achieve automatic filling. Therefore, a filling device that can solve the automatic filling problems of oily, high-viscosity, 3 mm - 15 mm large particle douchi sauce is needed. Summary of the Invention

[0004] In view of the above problems, the technical problem to be solved by the present invention is to provide an automatic filling device for douchi sauce, which separates the oil from the douchi sauce and then fills them separately, solving problems such as blockage during the automatic filling process of oily, high-viscosity, 3 mm - 15 mm large particle douchi sauce.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is as follows: An automatic filling device for douchi sauce, including an oil filtering mechanism for separating the oil from the douchi sauce, a filling bottle conveying mechanism for conveying filling bottles, a stirring hopper for temporarily storing douchi material above the filling bottle conveying mechanism, a filling mechanism communicating with the stirring hopper for filling douchi material into the filling bottles, a pressing mechanism for pressing the douchi in the filling bottles, an oil filling mechanism for filling the separated oil, and a main control electric box. The filling bottle conveying mechanism is sequentially provided with a first filling station, a middle section pressing station, a second filling station, and an oil filling station along its conveying direction. The filling mechanism is arranged at the first filling station, the pressing mechanism is arranged at the middle section pressing station, and the oil filling mechanism is arranged at the oil filling station.

An oil discharge pipe is provided on the oil storage tank, and an oil discharge valve is provided on the oil discharge pipe. A limiting support rod extending outward is provided on one side of the upper part of the filtering hopper. When the filtering hopper rotates to the position where the material opening faces upward, the limiting support rod can support on the top of the vehicle frame.

[0007] Preferably, a hoist is further included, and the hoist is used to lift the separated fermented soybean material to the stirring tank.

[0008] Preferably, a bottle separating and conveying mechanism is further included, which is used to separate the filling bottles and then convey them to the filling and conveying mechanism.

[0009] Preferably, the filling mechanism includes a filling head and a first lifting member for controlling the lifting of the filling head, so that the filling head can descend and gently press the material during the filling process. The filling head is communicated with the stirring tank through a material pipe.

[0010] Preferably, the filling head includes a filling head body, a filling nozzle provided at the bottom of the filling head body, and a filling nozzle lifting cylinder installed in the filling head body.

[0011] Preferably, the material pressing mechanism includes a material pressing head and a second lifting member for controlling the lifting of the material pressing head, so that the material pressing head can descend to press the fermented soybean material in the filling bottle.

[0012] Preferably, an anti-dripping mechanism is further provided at each filling station. The anti-dripping mechanism includes an anti-dripping tray provided below the filling head and a horizontal moving mechanism for controlling the horizontal front-back movement of the anti-dripping tray.

[0013] Preferably, the oil filling mechanism includes an oil tank, an oil filling nozzle, an oil filling metering cylinder, and an oil-water separator. The oil discharge pipe is communicated with the oil tank through a hot oil delivery pump. An oil filling rack is provided on one side of the filling bottle conveying mechanism, and a plurality of the oil filling nozzles are installed on the oil filling rack. The oil filling nozzle is connected to the oil tank through the oil filling metering cylinder. One end of the oil-water separator is connected to the air source, and the other end is connected to the air inlet end of the oil filling metering cylinder. An air flow regulating valve is connected to the air inlet end of the oil filling metering cylinder. An encoder is installed on the oil filling metering cylinder. An oil filling control electric box is provided on one side of the oil filling rack.

[0014] Preferably, a third lifting member for controlling the lifting of the oil filling nozzle is provided on the oil filling rack.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By separating the oil from the fermented soybean paste and then filling the oil and the paste separately, the present invention avoids the problems that the oil and the paste are likely to cause blockage of the conveying pipeline or the nozzle due to different flow velocities and uneven distribution of sauce particles. It is applicable to the filling of sauces with oil, high viscosity, low fluidity, and large particles.

[0017] The filling process of the fermented soybean paste in the present invention is divided into the first filling, the middle-stage pressing, and the second filling. After the first filling, the fermented soybean paste in the filling bottle is compacted through the middle-stage pressing and then the second filling is carried out. The three-step filling method for the fermented soybean paste solves the problem that the fluffy fermented soybean paste is likely to overflow from the bottle mouth during the filling process.

The appearance of this phrase at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0035] Such as Figures 1-3As shown in the figure, a kind of automatic filling equipment for fermented soybean paste sauce includes an oil filtering mechanism 1 for separating oil from the fermented soybean paste sauce, a filling bottle conveying mechanism 8 for conveying filling bottles, a stirring material box 4 for temporarily storing fermented soybean paste material above the filling bottle conveying mechanism 8, a filling mechanism 6 communicated with the stirring material box 4 for filling the fermented soybean paste material into the filling bottles, a material pressing mechanism 5 for pressing the fermented soybean paste in the filling bottles, an oil adding mechanism 10 for filling the separated oil, and a main control electric box 3. Along the conveying direction of the filling bottle conveying mechanism 8, a first filling station, a middle section material pressing station, a second filling station and an oil adding station are sequentially arranged. The filling mechanism 6 is arranged at the first filling station, the material pressing mechanism 5 is arranged at the middle section material pressing station, and the oil adding mechanism 10 is arranged at the oil adding station. By separating the oil and material and then filling them separately after oil filtering, the present invention avoids problems such as uneven distribution of sauce particles and material blockage caused by different oil and material flow rates. The fermented soybean paste material adopts a three-step filling method of first filling, middle section material pressing and second filling, effectively solving the problem that the fluffy fermented soybean paste material is easy to overflow from the bottle mouth during the filling process.

[0036] As Figure 4 and Figure 5 shown in the figure, the oil filtering mechanism 1 includes a filtering hopper 13 and an oil storage tank 12 which are arranged up and down on a vehicle frame 11. The filtering hopper 13 is rotationally connected to the vehicle frame 11 through a bearing 131. A filter screen 18 is arranged at the bottom of the filtering hopper 13. An oil discharge pipe 14 is arranged on the oil storage tank 12, and an oil discharge valve 15 is arranged on the oil discharge pipe 14. A limiting support rod 19 extending outward is arranged on one side of the upper part of the filtering hopper 13. When the filtering hopper 13 rotates to the position where the material opening faces upward, the limiting support rod 19 can support on the top of the vehicle frame 11. A trolley armrest 16 is arranged at one end of the vehicle frame 11, and moving casters 17 are arranged at the bottom of the vehicle frame 11, which is convenient for moving the filtering mechanism. During use, the stir-fried fermented soybean paste sauce is put into the filtering hopper 13. After being filtered by the filter screen 18, the filtered oil flows into the oil storage tank 12, and the fermented soybean paste material remains on the filter screen 18. Since the filtering hopper 13 can rotate, it is convenient to rotate the filtering hopper 13 to pour out the filtered fermented soybean paste material, and the limiting support rod 19 ensures the stability of the filtering hopper 13 during the filtering process.

[0037] As Figure 2 shown in the figure, the automatic filling equipment further includes a hoist 9, and the hoist 9 is used to lift the separated fermented soybean paste material to the stirring material box 4. The fermented soybean paste material filtered by the oil filtering mechanism 1 can be poured into the feed inlet of the hoist 9 by rotating the filtering hopper 13, and is conveyed and lifted to the stirring material box 4 by the hoist 9. The hoist 9 can adopt an existing mechanism.

[0038] As Figure 3As shown in the figure, in order to facilitate multi-bottle filling and improve filling efficiency, the automatic filling device further includes a bottle separating and conveying mechanism 2, which is used to separate the filling bottles and then convey them to the filling and conveying mechanism. The bottle separating and conveying mechanism 2 includes a conveyor belt, a plurality of bottle separating openings provided at the end of the conveyor belt, and a pushing cylinder for pushing the filling bottles out of the bottle separating openings.

[0039] As Figure 8 shown in the figure, the filling mechanism 6 includes a filling head 61 and a first lifting member 62 for controlling the lifting of the filling head 61, so that the filling head 61 can descend and gently press the material during the filling process. The filling head 61 is communicated with the stirring and feeding tank 4 through a material pipe. The filling head 61 includes a filling head body 611, a filling nozzle 612 provided at the bottom of the filling head body 611, and a lifting cylinder of the filling nozzle 612 installed inside the filling head body 611. In this embodiment, the first lifting member 62 includes a filling and pressing cylinder 621. A mounting box body is provided on the front side of the stirring and feeding tank 4. A fixing frame 622 for fixing the filling and pressing cylinder 621 is provided inside the mounting box body. The lower end of the mounting box body is slidably connected with a first fixing plate 623. The filling head 61 is fixed on the first fixing plate 623. The telescopic end of the filling and pressing cylinder 621 is connected to the first fixing plate 623. During the filling process, since the filling head 61 can be lifted and lowered and gently press the material, it is ensured that the material does not come out of the bottle mouth. The filling process adopts a weighing and quantitative control method for measurement. A weighing sensor is provided on the filling bottle conveying mechanism 8, which belongs to the existing measurement method and will not be elaborated here.

[0040] As Figure 6 shown in the figure, the pressing mechanism 5 includes a pressing head 51 and a second lifting member 52 for controlling the lifting of the pressing head 51, so that the pressing head 51 can descend to press the fermented soybean material in the filling bottle. In this embodiment, specifically, the second lifting member 52 includes a middle-section pressing cylinder 521, a first guide rod 522, and a first guide sleeve 523. A mounting plate 524 is fixed on the filling machine frame. The middle-section pressing cylinder 521 is fixed on the top of the mounting plate 524. A second fixing plate 525 for fixing the pressing head 51 is provided below the mounting plate 524. The telescopic end of the middle-section pressing cylinder 521 is connected to the second fixing plate 525. First guide rods 522 extending upward are provided on both sides of the top of the second fixing plate 525. First guide sleeves 523 that are movably sleeved in cooperation with the first guide rods 522 are provided on the mounting plate 524. The second lifting member 52 uses the middle-section pressing cylinder 521 and the guiding mechanism to cooperate to control the lifting of the pressing head 51, ensuring the smoothness of the movement. After the first filling, the pressing head 51 presses the fermented soybean material in the filling bottle to compact the fermented soybean material in the bottle and prevent the fluffy fermented soybean material from easily overflowing from the bottle mouth during the filling process.

[0041] As Figure 7As shown in the figure, in order to prevent dripping, a drip prevention mechanism 7 is also provided at each filling station. The drip prevention mechanism 7 includes a drip prevention tray 71 and a horizontal movement mechanism 72 for controlling the horizontal movement of the drip prevention tray 71 back and forth. In this embodiment, the horizontal movement mechanism 72 includes a drip prevention tray cylinder 721, a second guide rod 724, and a second guide sleeve 723. The drip prevention tray 71 is disposed below the filling head 61. A fixed rod 725 is vertically provided on the filling machine frame. The upper end of the fixed rod 725 is connected to a third fixing plate 723. The drip prevention tray cylinder 721 is horizontally fixed in the middle of the outer side of the third fixing plate 723. The outer ends of both sides of the drip prevention tray 71 extend outward to form second guide rods 724. A first guide sleeve 523 that is movably sleeved in cooperation with the first guide rod 522 is provided on the third fixing plate 723. Through the cooperation of the drip prevention tray cylinder 721 and the guiding mechanism, the smoothness of the horizontal movement of the drip prevention tray 71 is ensured. Since the drip prevention tray 71 can move horizontally, it can move to the outside during the filling process without affecting the filling of the filling head 61. After the filling is completed, the drip prevention tray 71 can move to directly below the filling head 61 to prevent the material from dripping onto the conveying track.

[0042] As Figure 9 shown, the refueling mechanism 10 includes a fuel tank 101, a fuel nozzle 104, a refueling metering cylinder 105, and an oil-water separator 103. The drain pipe 14 is connected to the fuel tank 101 through a hot oil transfer pump. A refueling rack 107 is provided on one side of the filling bottle conveying mechanism 8. A number of fuel nozzles 104 are installed on the refueling rack 107. A refueling metering cylinder 105 is connected between the fuel nozzle 104 and the fuel tank 101. One end of the refueling metering cylinder 105 connected to the oil-water separator 103 is connected to the air source, and the other end is connected to the air inlet end of the refueling metering cylinder 105. An air flow regulating valve is connected to the air inlet end of the refueling metering cylinder 105. An encoder is installed on the refueling metering cylinder 105. A refueling control electrical box 102 is provided on one side of the refueling rack 107. The refueling filling speed is adjusted through the air flow regulating valve on the refueling metering cylinder 105, and the size of the filling volume is measured through the encoder on the refueling metering cylinder 105, ensuring the refueling metering accuracy.

[0043] As Figure 9 shown, in order to facilitate the adjustment of the height of the fuel nozzle 104, a third lifting member 106 for controlling the lifting of the fuel nozzle 104 is provided on the refueling rack 107. The third lifting member 106 includes a bracket 1061, a moving plate 1064, a screw rod 1062, and an adjusting handwheel 1063. The moving plate 1064 is movably sleeved on the vertical rod of the bracket 1061 through a sleeve. The screw rod 1062 is vertically threadedly connected to the top of the bracket 1061. The lower end of the screw rod 1062 is rotatably connected to the moving plate 1064. The upper end of the screw rod 1062 is connected to the adjusting handwheel 1063. By rotating the adjusting handwheel 1063, the moving plate 1064 is driven to descend, thereby realizing the height adjustment of the fuel nozzle 104 to adapt to the refueling filling of bottles with different heights.

[0044] The working principle of the device is as follows: First, the stir-fried fermented soybean paste is sent to the filtering hopper 13. After being filtered by the filter screen 18, the separation of oil and fermented soybean paste is achieved. Secondly, through the rotating filtering hopper 13, the granular materials such as fermented soybean materials after filtering the oil are transferred to the elevator 9. The elevator 9 transports the granular materials such as fermented soybean materials to the stirring hopper 4. Through the stirring of the stirring hopper 4, the problem of material accumulation is solved. At the same time, the filtered high-temperature oil is transferred to the fuel tank 101 of the fuel adding mechanism 10 through the hot oil delivery pump. The stirring hopper 4 is provided with two outlets, which are respectively communicated with the filling heads 61 at the first filling station and the filling heads 61 at the second filling station. When the filling bottle is transported to the first filling station through the filling bottle conveying mechanism 8, the fermented soybean materials are filled for the first time. Then it continues to be transported to the middle section pressing station. Through the pressing mechanism 5, the fluffy fermented soybean granular materials in the filling bottle are compacted, and then it continues to be transported to the second filling station for the second filling of the fermented soybean materials, completing the filling of the fermented soybean materials. Finally, the filling bottle filled with fermented soybean materials is transported to the fuel adding station. The encoder on the fuel adding metering cylinder 105 controls the fuel filling amount, and the air flow regulating valve on the fuel adding metering cylinder 105 controls the fuel filling speed, realizing the metering filling of the fuel adding nozzle 104, and finally realizing the automatic filling of the fermented soybean paste with oil, poor flowability, and large particulate matters.

[0045] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
