Description

Technical Field

[0001] The utility model belongs to the technical field of quantitative feeding equipment, and in particular relates to quantitative feeding equipment for rice packaging. Background Art

[0002] During the rice packaging process, it is necessary to convey it quantitatively so that the quality of rice in each package is the same. The existing quantitative conveying of rice packaging often adopts an elastic weighing method. The rice falls into a container on an elastic bracket. The rice gradually increases, causing the container to compress the elastic bracket until the bottom of the bracket touches the sensor and the addition is automatically stopped. The rice in the container is then put into a packaging bag to achieve quantitative conveying. However, when using this quantitative conveying method, the impact force of the falling rice will affect the descent of the container and the elastic bracket. Excessive impact force can easily cause the bracket to touch the sensor in advance, resulting in inaccurate rice quantitative measurement. In addition, after the bracket touches the sensor, some rice is still in the air between the discharge port and the container, and will still fall into the container after the addition is stopped, which will also cause inaccurate rice quantitative measurement. Utility Model Content

[0003] The utility model aims to provide a quantitative feeding device for rice packaging, so as to solve the problem of inaccurate rice quantitative feeding of the existing quantitative feeding device for rice packaging.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A quantitative feeding device for rice packaging comprises a frame and a plurality of supporting legs fixed to the bottom of the frame, wherein a material storage trough is provided on the top of the frame, a material discharge trough is provided in the frame below the material storage trough, a flow guide frame is fixedly installed on the bottom of the frame, a quantitative cylinder is rotatably installed in the frame between the material storage trough and the flow guide frame, a quantitative adjustment mechanism is provided in the quantitative cylinder, and a quantitative cavity is formed between one side of the quantitative adjustment mechanism and the inner wall of the quantitative cylinder, and the quantitative cavity can be connected with the material discharge trough and the flow guide frame in sequence through the rotation of the quantitative cylinder.

[0006] Preferably, the quantitative adjustment mechanism separates the quantitative cylinder into two quantitative chambers, and two connecting grooves are provided on the quantitative cylinder, and the two connecting grooves correspond to the two quantitative chambers one by one.

[0007] Preferably, a stirring mechanism is rotatably connected to the frame in the material storage trough, and the stirring mechanism is located above the material discharge trough.

[0008] Preferably, the stirring mechanism includes a stirring shaft and a plurality of stirring rods fixedly connected to the outside of the stirring shaft.

[0009] Preferably, a first motor is fixedly mounted on one side of the frame, and an output shaft of the first motor is fixedly connected to the stirring shaft.

[0010] Preferably, a rotating shaft is fixedly mounted on one side of the metering cylinder, and pulleys are coaxially fixed to one end of the rotating shaft and the stirring shaft, and a belt is connected between the two pulleys for transmission.

[0011] Preferably, the quantitative adjustment mechanism comprises two slides symmetrically slidably connected in the quantitative cylinder and two adjustment plates arranged on both sides of the two slides, and a connecting rod is rotatably connected between the slides and the adjustment plates.

[0012] Preferably, a slide groove slidably matched with the slide bracket is provided in the metering cylinder.

[0013] Preferably, a double-headed screw is rotatably connected inside the metering cylinder, and the two slides are respectively screwed and connected to the two ends of the double-headed screw.

[0014] Preferably, a second motor is fixedly mounted on one side of the metering cylinder, and an output end of the second motor is fixedly connected to a double-headed screw.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] (1) The utility model is provided with a metering cylinder. After the rice enters the metering cavity of the metering cylinder from the material storage tank and is filled, the metering cavity is connected with the guide frame through the rotation of the metering cylinder, and the rice flows out of the guide frame and is bagged. The quantitative feeding process adopts the method of quantitative cavity constant volume to quantify the rice, and the impact force of the rice falling will not cause any influence. When the metering cavity is disconnected from the material storage tank, the outer wall of the metering cylinder automatically closes the material storage tank, and there is no rice in the air to affect the quantitative quantity, so this quantitative method is more accurate.

[0017] (2) The utility model is provided with a stirring mechanism. During the quantitative process, the stirring mechanism is reciprocated slightly by the first motor, so that the stirring mechanism stirs the rice near the discharge trough to prevent blockage. At the same time, the belt drive is used to make the metering cylinder also reciprocate slightly, so that the rice is filled more fully and the quantitative quantity is more accurate. After the quantitative quantity is completed, the stirring mechanism rotates half a circle, so that the connecting groove on the metering cylinder rotates to the bottom for unloading, thereby realizing automatic quantitative feeding of the equipment with higher efficiency.

[0018] (3) The utility model is provided with a quantitative adjustment mechanism, which drives the double-headed screw to rotate through the second motor, so that the two slides are moved closer to or farther away from each other, thereby realizing the movement of the adjustment plate in the quantitative cylinder through the connecting rod, thereby changing the size of the quantitative cavity between the adjustment plate and the quantitative cylinder, which can be used to quantify rice packaged in different specifications, thereby increasing practicality.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 5 As shown, the utility model provides the following technical solutions:

[0027] A quantitative feeding device for rice packaging comprises a frame 1 and a plurality of supporting legs 8 fixed to the bottom of the frame 1, a material storage trough 5 is provided on the top of the frame 1, a material discharge trough 16 is provided below the material storage trough 5 in the frame 1, a flow guide frame 7 is fixedly installed on the bottom of the frame 1, a quantitative cylinder 10 is rotatably installed between the material storage trough 5 and the flow guide frame 7 in the frame 1, a quantitative adjustment mechanism is provided in the quantitative cylinder 10, and a quantitative cavity is formed between one side of the quantitative adjustment mechanism and the inner wall of the quantitative cylinder 10, and the quantitative cavity can be connected with the material discharge trough 16 and the flow guide frame 7 in sequence through the rotation of the quantitative cylinder 10.

[0028] Based on the above disclosed structure, when performing quantitative feeding of rice:

[0029] First, the quantitative adjustment mechanism is adjusted according to the required quantitative quantity, so that the quantitative cavity in the quantitative cylinder 10 reaches the set volume, and the rice to be quantitatively fed is added from the top of the frame 1 to the storage tank 5, and then the quantitative cylinder 10 is rotated to make the quantitative cylinder 10 communicate with the discharge trough 16 at the bottom of the storage tank 5. Due to gravity, the rice falls from the storage tank 5 to the quantitative cavity in the quantitative cylinder 10 and gradually fills the quantitative cavity. Then the quantitative cylinder 10 is rotated to separate it from the discharge trough 16. At the same time, the outer wall of the quantitative cylinder 10 blocks the discharge trough 16 to prevent the rice in the storage tank 5 from continuing to fall. The quantitative cylinder is rotated to communicate with the bottom guide frame 7, so that the rice in the quantitative cavity falls into the guide frame 7 and continues to fall along the guide frame 7 to one side for bagging, thereby completing the quantitative feeding of rice.

[0030] Preferably, the quantitative adjustment mechanism separates the quantitative cylinder 10 into two quantitative chambers, and two connecting grooves 15 are provided on the quantitative cylinder 10, and the two connecting grooves 15 correspond to the two quantitative chambers one by one. Figure 3 As shown, the two quantitative chambers correspond to each other up and down, and the two connecting grooves 15 can be connected with the discharge groove 16 and the guide frame 7 respectively at the same time, so that in the process of quantitative feeding, the upper quantitative chamber is quantitatively filled, and at the same time, the lower quantitative chamber discharges the quantitative rice into bags, thereby improving the efficiency of quantitative feeding and further improving the efficiency of rice packaging.

[0031] As mentioned above, regarding the rotation of the metering cylinder 10, it is preferably provided with the following structure:

[0032] A stirring mechanism is rotatably connected to the material storage tank 5 on the frame 1, and the stirring mechanism is located above the material discharge tank 16;

[0033] The stirring mechanism includes a stirring shaft 17 and a plurality of stirring rods 6 fixedly connected to the outside of the stirring shaft 17;

[0034] A rotating shaft 2 is fixedly mounted on one side of the metering cylinder 10, and a pulley 4 is coaxially fixed to one end of the rotating shaft 2 and the stirring shaft 17, and a belt 3 is connected between the two pulleys 4 for transmission;

[0035] A first motor 9 is fixedly mounted on one side of the frame 1 , and an output shaft of the first motor 9 is fixedly connected to the stirring shaft 17 .

[0036] As can be seen from the above, the first motor 9 drives the stirring shaft 17 to rotate, so that the pulley 4 on the stirring shaft 17 rotates, and then the belt 3 is transmitted, so that another pulley 4 drives the rotating shaft 2 to rotate, so that the rotating shaft 2 drives the metering cylinder 10 to rotate.

[0037] Preferably, when the quantitative cavity is filled with rice, the first motor 9 can drive the stirring shaft 17 to swing back and forth in a small amplitude, so that the stirring shaft 17 drives the stirring rod 6 to rotate, and then stirs the rice near the discharge trough 16, which is beneficial to prevent the rice from clogging the discharge trough 16. At the same time, through the transmission of the two pulleys 4 and the belt 3, the quantitative cylinder 10 also swings back and forth in a small amplitude, thereby playing the role of shaking and vibrating the quantitative cylinder 10, so that the rice filling in the quantitative cavity is more uniform, and then the quantitative measurement is more accurate; then the first motor 9 drives the stirring shaft 17 to rotate half a circle, so that the filled quantitative cavity rotates to the bottom, and the empty quantitative cavity rotates to the top to continue quantitative measurement;

[0038] In addition, since the two quantitative chambers of this embodiment can perform quantitative measurement and discharge at the same time, the small reciprocating swing during the quantitative process can also speed up the quantitative chamber at the bottom and discharge the rice, while preventing the rice from being blocked in the quantitative chamber, which is conducive to the complete discharge of the rice and makes the quantitative measurement more accurate.

[0039] In addition, regarding the quantitative adjustment mechanism, it is preferred to have the following structure:

[0040] The quantitative adjustment mechanism includes two slides 13 symmetrically slidably connected to the quantitative cylinder 10 and two adjustment plates 14 arranged on both sides of the two slides 13. A connecting rod 19 is rotatably connected between the slides 13 and the adjustment plates 14.

[0041] The metering cylinder 10 is provided with a slide groove 12 which is slidably matched with the slide 13;

[0042] A double-headed screw 18 is rotatably connected inside the metering cylinder 10, and two slides 13 are screwed and connected to both ends of the double-headed screw 18 respectively;

[0043] A second motor 11 is fixedly mounted on one side of the metering cylinder 10 , and an output end of the second motor 11 is fixedly connected to a double-headed screw 18 .

[0044] As can be seen from the above, when the volume of the quantitative chamber is adjusted according to the required quantitative quantity, the specific operation is as follows: taking the reduction of the volume of the quantitative chamber as an example, the second motor 11 is started to drive the double-headed screw 18 to rotate, so that the two slides 13 screwed together at both ends of the double-headed screw 18 move toward both ends along the slide 12 at the same time, thereby through the connecting rod 19 rotatably connected between the slide 13 and the adjusting plate 14, the adjusting plates 14 on both sides slide in the quantitative cylinder 10 in the direction away from the slide 13, thereby reducing the volume of the quantitative chamber between the adjusting plate 14 and the quantitative cylinder 10; conversely, the second motor 11 is started to drive the double-headed screw 18 to rotate in the opposite direction, so that the adjusting plates 14 on both sides slide in the quantitative cylinder 10 in the direction close to the slide 13, thereby increasing the volume of the quantitative chamber between the adjusting plate 14 and the quantitative cylinder 10; in summary, the volume of the quantitative chamber can be changed by the quantitative adjustment mechanism, so that the device can be applied to the quantitative feeding process of rice packaging of different specifications, making the device more practical.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
