Description

Technical Field

[0001] The utility model relates to the technical field of seed quantitative packaging machines, and specifically discloses a seed quantitative packaging machine. Background Art

[0002] In order to facilitate weighing of packaging bags, the discharge pipe and the clamping pipe of the existing seed quantitative packaging machine are not directly connected. When the seed quantitative packaging machine detects that the weight of the seeds in the packaging bag reaches the set value, it will stop in time. However, there are still seeds remaining in the discharge pipe. Under the action of their own gravity, the seeds will still fall from the inside of the discharge pipe through the clamping pipe into the packaging bag, which can easily cause deviation in the weight of the seeds inside the packaging bag. In addition, the support plate set on the belt conveyor cannot be moved, and the packaging bag needs to be manually moved to the conveyor belt, which is very inconvenient. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies in the prior art, the present application aims to provide a seed quantitative packaging machine, comprising a packaging machine body, a belt conveyor and a sealing machine placed on the outside of the packaging machine body, a screw conveyor arranged on the packaging machine body, a discharge pipe arranged at the bottom of the screw conveyor, a clamping pipe installed on the packaging machine body through a weighing assembly and located on the outside of the discharge pipe, and a controller installed on one side of the packaging machine body, a two-position three-way solenoid valve located above the clamping pipe and electrically connected to the controller is fixedly installed on the outside of the packaging machine body, a blocking mechanism is installed on the inside of the discharge pipe, a fixed plate is fixedly installed on one side of the belt conveyor, and a support plate located above the belt conveyor and below the clamping pipe is mounted on the inside of the fixed plate, a cylinder with one end fixedly mounted on the outside of the support plate is fixedly installed on the outside of the fixed plate, and a high-pressure pipe and a negative-pressure pipe are connected to the interior of the top of the two-position three-way solenoid valve.

[0004] Preferably, the blocking mechanism includes a first airbag and a second airbag placed on the inside of the discharge pipe, a limit frame sleeved on the outside of both sides of the discharge pipe, and an adapter connected to the bottom of the two-position three-way solenoid valve. The opposite sides of the first airbag and the second airbag are provided with air nozzles sleeved inside the discharge pipe. The outer side of one end of the air nozzle extending out of the discharge pipe is threaded with a nut, the interior of the air nozzle is connected to a hard air pipe located on the inside of the clamping tube, the outer side of the top end of the hard air pipe is connected to a flexible air pipe connected to the inside of the adapter, and the internal thread of the top of the limit frame is threaded with a bolt.

[0005] Preferably, a limiting plate is provided at the bottom of the discharge pipe.

[0006] Preferably, the top of the belt conveyor is internally sheathed with steel balls located at the bottom of the support plate. Beneficial effects

[0007] 1. The seed quantitative packaging machine starts the two-position three-way solenoid valve so that the high-pressure gas inside the high-pressure pipe can be transported to the first airbag and the second airbag through the adapter, and then the rapid expansion of the first airbag and the second airbag can effectively block the discharge port inside the discharge pipe. When the seed quantitative packaging machine detects that the seed weight in the packaging bag reaches the set value, the seeds remaining in the discharge pipe will not fall into the packaging bag, ensuring that the seed weight inside the packaging bag is not prone to deviation. Even if there are seeds remaining between the first airbag and the second airbag, the airbags will not damage the seeds.

[0008] 2. The seed quantitative packaging machine can limit the packaging bags that fall on the support plate through the fixed plate, and can drive the support plate to move outside the steel ball while gradually pulling the support plate out from the bottom of the packaging bag through the drive of the cylinder. At this time, the packaging bag gradually falls on the conveyor belt on the belt conveyor under the action of its own gravity for transportation, which is more convenient to use.

[0015] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0016] The drawings in the embodiments of the present invention: different types of section lines in the drawings are not marked according to national standards, nor do they impose any requirements on the materials of the components. Instead, they are used to distinguish the cross-sectional views of the components in the drawings.

[0017] See also Figure 1-4 A seed quantitative packaging machine includes a packaging machine body 1, a belt conveyor 2 and a sealing machine 3 placed outside the packaging machine body 1, a screw conveyor 4 arranged on the packaging machine body 1, a discharge pipe 5 arranged at the bottom of the screw conveyor 4, a clamping pipe 7 installed on the packaging machine body 1 and located outside the discharge pipe 5 through a weighing component 6, and a controller 8 installed on one side of the packaging machine body 1. A two-position three-way solenoid valve 9 is fixedly installed on the outside of the packaging machine body 1 and is located above the clamping pipe 7 and is electrically connected to the controller 8. A blocking mechanism 10 is installed on the inside of the discharge pipe 5. A fixing plate 11 is fixedly installed on the side, and a support plate 12 is mounted on the inner side of the fixing plate 11, which is located above the belt conveyor 2 and below the clamping tube 7. A cylinder 13 is fixedly installed on the outer side of the fixing plate 11, one end of which is fixedly mounted on the outer side of the support plate 12. The top of the two-position three-way solenoid valve 9 is internally connected with a high-pressure pipe 14 and a negative-pressure pipe 15. The L end and R end of the two-position three-way solenoid valve 9 are respectively connected to the high-pressure pipe 14 and the negative-pressure pipe 15. The first airbag 101 and the second airbag 102 can be inflated and exhausted by driving the two-position three-way solenoid valve 9 to facilitate the opening and closing of the discharge port of the discharge pipe 5.

[0018] Among them, the blocking mechanism 10 includes a first air bag 101 and a second air bag 102 placed on the inner side of the discharge pipe 5, a limit frame 103 sleeved on the outside of both sides of the discharge pipe 5, and a adapter 104 connected to the bottom of the two-position three-way solenoid valve 9. The opposite sides of the first air bag 101 and the second air bag 102 are provided with an air nozzle 105 sleeved inside the discharge pipe 5. The outer side of the end of the air nozzle 105 extending out of the outside of the discharge pipe 5 is threadedly sleeved with a nut 106. By tightening the nut 106, the first air bag 101 and the second air bag 102 can be stably fixed on the inner side of the discharge pipe 5. The interior of the air nozzle 105 is connected to a hard air pipe 107 located on the inner side of the clamping tube 7. The hard air pipe 107 The outer side of the top is connected to a flexible air tube 108 connected to the inside of the adapter 104, and the internal thread of the top of the limit frame 103 is sleeved with a bolt 109. The limit frame 103 can be used to limit and support the first airbag 101 and the second airbag 102, so that when the first airbag 101 and the second airbag 102 are inflated, they will not deviate to the outside of the discharge pipe 5, ensuring that the first airbag 101 and the second airbag 102 can cover the discharge port of the discharge pipe 5 after they expand and contact, and the limit frame 103 can be limited and fixed by the bolt 109, and the limit of the limit frame 103 can be released by loosening the bolt 109, so as to facilitate the disassembly and assembly of the first airbag 101 and the second airbag 102.

[0019] Among them, a limiting plate 16 is provided at the bottom of the discharge pipe 5, which can avoid the first airbag 101 and the second airbag 102 while facilitating the installation of the two. The limiting plate 16 can also provide limiting support for the first airbag 101 and the second airbag 102 when they are inflated, preventing the expanded parts of the first airbag 101 and the second airbag 102 from detaching from the inside of the discharge pipe 5.

[0020] Among them, the top of the belt conveyor 2 is internally mounted with a steel ball 17 located at the bottom of the support plate 12. The steel ball 17 can reduce the friction between the belt conveyor 2 and the support plate 12, making it easy to pull the support plate 12 out from the bottom of the packaging bag when the cylinder 13 is driven.

[0021] When the packaging machine is in use, the controller 8 controls the screw conveyor 4 to start, and the seeds are transported to the inside of the packaging bag through the discharge pipe 5 by the drive of the screw conveyor 4. When the weighing component 6 detects that the weight of the seeds in the packaging bag reaches the set value, the controller 8 closes the screw conveyor 4 and starts the L end of the two-position three-way solenoid valve 9. At this time, the high-pressure gas inside the high-pressure pipe 14 is transported to the inside of the first air bag 101 and the second air bag 102 through the two-position three-way solenoid valve 9 via the adapter 104, the flexible air pipe 108, the hard air pipe 107 and the air nozzle 105. As the gas gradually increases, the first air bag 101 and the second air bag 102 expand under the action of the gas pressure. When the opposing surfaces of the first air bag 101 and the second air bag 102 are completely in contact, the transportation of the seeds inside the discharge pipe 5 is cut off by the first air bag 101 and the second air bag 102, and the clamping device on the outside of the clamping tube 7 is opened by the controller 8. The bag is opened and falls to the top of the support plate 12 under the action of gravity. The cylinder 13 is started by the controller 8. The support plate 12 is driven by the cylinder 13 to move along the outer side of the steel ball 17 while the support plate 12 is gradually pulled out from the bottom of the bag until the bag falls onto the conveyor belt on the belt conveyor 2. The bag is driven by the belt conveyor 2 to move while the bag mouth of the bag is transported to the inner side of the sealing machine 3 for sealing. When the second bag is clamped, the R end of the two-position three-way solenoid valve 9 is started by the controller 8. At this time, the interior of the first air bag 101 and the second air bag 102 is evacuated through the negative pressure tube 15. At this time, the seeds remaining in the discharge pipe 5 can automatically fall into the interior of the second bag. Repeat the above steps to load the second bag.
