Description

Technical Field

[0001] The invention relates to the technical field of rice packaging, and in particular to an integrated full-automatic rice packaging machine unit. Background Art

[0002] Rice processing: raw grain cleaning, rice husking, separation of rice and brown rice mixture, separation of immature grains from brown rice, rice milling, white rice grading, color sorting, polishing, white rice grading, and packaging.

[0003] The processed rice needs to be packaged. In order to increase the storage time of rice, the rice is vacuum-packaged. For example, Chinese patent CN218662723U discloses a rice vacuum automatic packaging machine. The design of the packaging machine integrates whole bag, bag clamping, canning, plastic sealing and vacuuming. It is fully functional and uses a rotatable hoisting conveyor belt to automatically complete the above process in a cycle. It has a high degree of automation and high work efficiency. However, when the packaging machine packages the rice, it only packages the rice once. In the subsequent rice transportation process, there may be a possibility of being punctured by external sharp objects, resulting in air leakage, which affects the storage time of the rice. Therefore, we propose an integrated rice automatic packaging unit. Summary of the invention

[0004] The purpose of the present invention is to provide an integrated full-automatic rice packaging unit, which has the function of secondary packaging to prevent air leakage of rice and thus improve the storage time.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: an integrated rice fully automatic packaging machine unit, including a supporting upright plate, a mounting top plate installed on the supporting upright plate, a lifting mechanism installed on the supporting upright plate, a quantitative discharging machine, a plastic sealing machine and a vacuum pump installed on the mounting top plate, and a packaging bag clamping cylinder installed on the lifting mechanism, a rectangular opening is opened on the supporting upright plate, a rotating mechanism is installed in the rectangular opening, two symmetrically distributed packaging bag bagging mechanisms are installed on the rotating mechanism, a material receiving mechanism is rotatably connected to the inner bottom wall of the rectangular opening, and the material receiving mechanism is meshed with the rotating mechanism through a transmission mechanism.

[0006] By adopting the above technical scheme, after the packaging bag clamping cylinder clamps the packaging bag, the lifting mechanism is started to drive the packaging bags clamped on the multiple packaging bag clamping cylinders to move one by one to the quantitative discharging machine to receive the materials, and then move one by one to the vacuum pump and the plastic sealing machine for vacuuming and sealing, so as to realize the automatic packaging of rice. After the rice packaging bag is opened by the packaging bag bagging mechanism, the rotating mechanism is started to drive the opened packaging bag on the packaging bag bagging mechanism to rotate continuously to the bottom of the plastic sealing machine, and the rice after the vacuum packaging is bagged once is bagged, so as to automatically realize the secondary packaging function of the rice, prevent the rice from leaking and achieve the effect of improving the preservation time. Then the receiving mechanism receives and seals the rice after the secondary bagging, and can automatically unload the rice after the secondary bagging, so as to have high packaging efficiency and save manpower.

[0007] The present invention is further configured as follows: the lifting mechanism includes two horizontal plates installed on the supporting vertical plates, a rotating shaft rotatably connected to the horizontal plates, a lifting belt that is transmission-connected to the two transmission shafts and wrapped around the outside of the supporting vertical plates, and a driving motor installed on one of the horizontal plates to drive the rotating shaft at the corresponding position to rotate.

[0008] By adopting the above technical solution, the driving motor is started to drive the corresponding rotating shaft to rotate, and the rotating shaft drives another rotating shaft to rotate through the lifting belt. After the packaging bag clamping cylinder clamps the packaging bag, the lifting belt drives multiple packaging bag clamping cylinders to move one by one to the quantitative discharge machine to receive the material, and then move one by one to the vacuum machine and the plastic sealing machine for vacuuming and sealing, thereby realizing the automatic packaging of rice.

[0009] The present invention is further configured as follows: the bag clamping cylinder is installed on the lifting belt, a plurality of the bag clamping cylinders are provided on the lifting belt, and two of the bag clamping cylinders form a group to clamp two sides of the opening of the rice bag respectively.

[0010] By adopting the above technical solution, multiple packaging bags can be clamped one by one in multiple groups of packaging bag clamping cylinders to achieve continuous operation of rice packaging.

[0011] The present invention is further configured as follows: the rotating mechanism includes a rotating motor installed in the rectangular opening, a rotating shaft rotatably connected to the inner wall of the rectangular opening and connected to the output shaft of the rotating motor, and a gear 1 installed outside the rotating shaft.

[0012] The present invention is further configured as follows: the packaging bag bagging mechanism includes a connecting rod installed on the rotating shaft, a connecting cross plate installed on the connecting rod, an electric slide rail installed on the connecting cross plate, and two bag-supporting blocks that slide towards or away from each other on the electric slide rail.

[0013] By adopting the above technical solution, the two bag-supporting blocks move closer to or farther away from each other on the electric slide rail, and the mouth of the secondary packaging bag is opened. The rotating motor is started to drive the connecting rod on the rotating shaft to rotate, so that the bag-supporting blocks on both sides can rotate continuously to the bottom of the plastic sealing machine, and the rice that has been vacuum-packed once is bagged, so that the secondary packaging function of the rice is automatically realized, and the rice is prevented from leaking, so as to achieve the effect of improving the storage time.

[0014] The present invention is further configured such that: after being opened, the distance between the two bag-opening blocks is greater than the distance between the two bag-clamping cylinders in the same group.

[0015] By adopting the above technical solution, the rice clamped by the bag clamping cylinder after the vacuum packaging can fall into the packaging bag opened by the bag supporting block.

[0016] The present invention is further configured as follows: the material receiving mechanism includes a rotating sleeve rotatably connected to the bottom wall of the rectangular opening and sleeved on the outside of the rotating shaft, a bottom plate rotatably connected to the outside of the rotating sleeve, a top plate sleeved on the outside of the rotating sleeve and sliding up and down on the outside thereof, a connecting spring sleeved on the outside of the rotating sleeve and located between the bottom plate and the top plate, an elastic support block installed on the bottom plate and abutting against the lower surface of the top plate, a material discharge channel provided on the elastic support block, a stopper installed on the rotating sleeve and abutting against the surface of the top plate, two material receiving frames installed on the top plate, two heat sealing blocks provided in the material receiving frames, a cylinder installed in the material receiving frames for driving the two heat sealing blocks to move closer to or away from each other, a material discharge port provided on the top plate and on the bottom wall of the material receiving frame, and a gear ring installed on the inner wall of the rotating sleeve.

[0017] By adopting the above technical scheme, after the bag-holding block holds open the mouth of the secondary-packaged packaging bag, the vacuum-packed rice falls into the packaging bag for the second time, and then the two bag-holding blocks are close to each other and no longer hold the mouth of the packaging bag. At this time, the packaging bag falls into the receiving frame, and then the cylinder is started to drive the two heat-sealing blocks to approach each other to seal the secondary-packaged rice, thereby automatically realizing the secondary packaging function of the rice, preventing air leakage of the rice, and achieving the effect of improving the preservation time. The receiving frame is installed on the rotating sleeve, and a connecting spring is provided between the bottom plate and the top plate to buffer the rice after the secondary bagging, thereby reducing the impact force of the bagged rice on the equipment, and having higher practicality.

[0018] The present invention is further configured as follows: the transmission mechanism includes a transmission rod rotatably connected to the inner bottom wall of the rectangular opening and a gear 2 installed on the transmission rod, the transmission rod is located on the inner side of the rotating sleeve, and the gear 2 is meshed with the gear 1 and the gear ring.

[0019] By adopting the above technical solution, when the rotating motor starts to drive the connecting rod on the rotating shaft to rotate, the gear one rotates synchronously with the rotating shaft, and because the gear one is meshed with the gear two, the gear two is driven to rotate, and the gear two is meshed with the gear ring, so that the rotating sleeve keeps rotating synchronously with the rotating shaft, and drives the top plate on the rotating sleeve to rotate. When the receiving frame with the rice after secondary packaging rotates to coincide with the unloading channel, the rice in the corresponding receiving frame enters the unloading channel along the unloading port to realize automatic unloading, and the packaging efficiency is high and manpower is saved; the bottom plate is rotatably connected to the rotating sleeve, and the top plate slides up and down outside the rotating sleeve, so that the bottom plate and the top plate can not only buffer the falling rice, but also make the two receiving frames on the top plate rotate to unload the rice, and the elastic support block is arranged between the bottom plate and the top plate, which can not only ensure that the bottom plate and the top plate can be buffered, but also can open a unloading channel on the elastic support block to cooperate with the unloading port to realize automatic unloading of rice.

[0020] The present invention is further configured as follows: the material discharge port on the top plate and the material discharge port on the material receiving frame are communicated with each other, and the material discharge channel corresponds to one of the packaging bag bagging mechanisms up and down.

[0021] By adopting the above technical scheme, the mutually connected unloading ports facilitate the discharge of the packaged rice in the receiving frame through the unloading channel, the two packaging bag bagging mechanisms are symmetrically distributed, and the two receiving frames respectively receive the packaging bags on the two bagging mechanisms. When the unloading channel corresponds to one of the packaging bag bagging mechanisms up and down, when the unloading port on one of the receiving frames coincides with the unloading channel to unload the rice, the other packaging bag bagging mechanism and the receiving frame are both rotated to the bottom of the plastic sealing machine to continue packaging the rice after the vacuum packaging, thereby realizing continuous operation of rice packaging with higher efficiency.

[0022] The present invention is further configured as follows: a bracket located below the quantitative discharging machine is also installed on the supporting vertical plate.

[0023] By adopting the above technical solution, when the quantitative discharging machine discharges rice into the packaging bag clamped by the packaging bag clamping cylinder, the bracket supports the packaging bag at the bottom, thereby improving the discharging stability of the quantitative discharging machine.

[0024] The beneficial effects of the present invention are:

[0025] 1. The two bag-supporting blocks move closer to or farther away from each other on the electric slide rail to open the mouth of the secondary-packaged bag. The rotating motor is started to drive the connecting rod on the rotating shaft to rotate, so that the bag-supporting blocks on both sides can rotate continuously to the bottom of the plastic sealing machine. After the bag-supporting blocks open the mouth of the secondary-packaged bag, the vacuum-packed rice falls into the packaging bag for the second time. Then the two bag-supporting blocks move closer to no longer support the mouth of the packaging bag. At this time, the packaging bag falls into the receiving frame. Then the cylinder is started to drive the two heat-sealing blocks to move closer to each other to seal the secondary-packaged rice, thereby automatically realizing the secondary packaging function of the rice and preventing the rice from leaking, thereby improving the shelf life.

[0026] 2. When the rotating motor starts to drive the connecting rod on the rotating shaft to rotate, gear one rotates synchronously with the rotating shaft, and because gear one is meshed with gear two, gear two is driven to rotate, and gear two is meshed with the gear ring, so that the rotating sleeve and the rotating shaft keep rotating synchronously, driving the top plate on the rotating sleeve to rotate, when the receiving frame filled with the secondary packaged rice rotates to coincide with the unloading channel, the rice in the corresponding receiving frame enters the unloading channel along the unloading port to realize automatic unloading, which has high packaging efficiency and saves manpower.

[0027] 3. The bottom plate is rotatably connected to the rotating sleeve, and the top plate slides up and down outside the rotating sleeve, so that the bottom plate and the top plate can not only buffer the falling rice, but also make the two receiving frames on the top plate rotate to discharge the rice.

[0028] 4. The elastic support block is arranged between the bottom plate and the top plate, which can ensure that there is a buffer between the bottom plate and the top plate, and a feeding channel and a feeding port can be opened on the elastic support block to cooperate with each other to realize automatic feeding of rice.

[0029] 5. The two packaging bag bagging mechanisms are symmetrically distributed, and the two receiving frames receive the packaging bags on the two bagging mechanisms respectively. When the unloading channel corresponds to one of the packaging bag bagging mechanisms, when the unloading port on one of the receiving frames coincides with the unloading channel to unload the rice, the other packaging bag bagging mechanism and the receiving frame are rotated to the bottom of the plastic sealing machine to continue to package the rice after the vacuum packaging, thereby realizing the continuous operation of rice packaging with higher efficiency.
