[0002] At present, the food industry is advancing rapidly, which makes the market's requirements for the specifications, quality, etc. of food packaging increasingly stringent. As a very common and popular food in people's daily diet, the packaging and sealing of peanuts are directly related to the quality preservation, transportation safety, and sales display of peanuts. Therefore, peanut packaging and sealing devices play an important role in the entire food packaging industry.

[0003] The related technology can refer to the Chinese patent with the publication number CN213008922U, which discloses a vacuum packaging device for leisure roasted nuts. It includes a transportation table, a first fixing block is fixedly installed at the left end of the transportation table, a second fixing block is fixedly installed at the right end of the transportation table, a first limiting block is fixedly installed at the right end of the first fixing block, a second limiting block is fixedly installed at the left end of the second fixing block, a hinge is fixedly installed at the upper end of the second limiting block, and a turning and pressing cover is fixedly installed at the left end of the hinge. This vacuum packaging device for leisure roasted nuts realizes the effect of evacuating and sealing multiple packaging bags at one time by setting the first pressing block, the second pressing block, the placing seat, and the turning and pressing cover, greatly improving the production rate.

[0004] In view of the above-mentioned related technology, when peanuts are vacuum-packaged, due to the irregular shape of peanut grains and large gaps between grains, during the vacuuming process, these gaps will cause uneven distribution of the vacuum degree in the packaging cavity, which may cause phenomena such as local bulging and deformation of the packaged peanut bags, affecting the sealing quality of peanuts. Summary of the Invention

[0005] In order to improve the sealing quality of peanuts, the present application provides a fully automatic moisture-proof sealing device for peanuts.

[0006] The present application provides a fully automatic moisture-proof sealing device for peanuts, adopting the following technical solutions: A fully automatic moisture-proof sealing device for peanuts, including a machine body.

Several vacuum suction plates I are arranged at the circular track. The packaging bag is placed on the vacuum suction plates I. Several vacuum suction plates I are all slidably connected to the circular track along the length direction of the circular track. A moving component for driving the vacuum suction plates I to move is provided at the upper end of the machine frame. A limiting component is provided at the upper end of the placement table.

The rotating rod is rotatably connected to the rotating box. A motor I is fixedly installed at the upper end of the machine body. The output shaft of the motor I is coaxially fixed to the rotating rod. A telescopic rod is vertically fixed to the rotating rod. The telescopic rod is vertically arranged and is inserted into the vibrating plate. An elastic part I is fixedly installed at one end of the telescopic rod close to the rotating plate. The end of the elastic part I away from the telescopic rod is fixedly connected to the vibrating plate. An elastic part II is fixedly installed between the vibrating plate and the rotating box. An adsorption component is provided at the upper end of the placement table. The adsorption component is used to adsorb the packaging bag. An air extraction component is provided at the upper end of the machine body. The air extraction component is used to extract the air in the packaging bag. A heat-sealing component is provided at the upper end of the machine frame. The heat-sealing component is used to seal the packaging bag.

[0007] By adopting the above technical solution, the moving component drives the vacuum suction plates I to move to the limiting component. The limiting component is activated to limit both ends of the packaging bag. The adsorption component adsorbs the packaging bag and drives the two sides of the packaging bag to move away from each other, creating a gap in the packaging bag. The motor I is activated to drive the rotating rod to rotate. The rotation of the rotating rod drives the telescopic rod to move upward to impact the vibrating plate, causing the vibrating plate to rotate. The vibration of the rotating plate drives the vibration of the vacuum suction plates I. The vibration of the vacuum suction plates I drives the vibration of the peanuts in the packaging bag, making the peanuts evenly arranged in the packaging bag. The air extraction component is activated to extract the air in the packaging bag, and then the heat-sealing component performs a sealing treatment on the packaging bag. The peanuts are evenly arranged in the packaging bag, making the vacuum degree distribution in the packaging bag after air extraction uniform, reducing the probability of the packaging bag bulging after air extraction, and improving the sealing quality of the peanuts.

[0008] Optionally, the limiting component includes a moving plate, a cylinder I, and two pressing blocks. The cylinder I is fixedly installed at the upper end of the placement table and is vertically arranged. The moving plate is coaxially fixed to the output end of the cylinder I. The two pressing blocks are respectively located on both sides of the moving plate. The pressing blocks are slidably connected to the moving plate in the vertical direction. An elastic part III is fixedly installed between the pressing blocks and the moving plate. The elastic part III is used to drive the pressing plate to move vertically.

[0009] By adopting the above technical solution, the cylinder I is activated to drive the moving plate to move downward. The downward movement of the moving plate drives the pressing blocks to move downward. The pressing blocks move downward to press both ends of the packaging bag, reducing the probability of the packaging bag displacing during the vibration of the peanuts in the packaging bag and improving the stability of the device.

[0010] Optionally, a pressing block is fixedly provided at the lower end of the moving plate. The pressing block is located at the lower end of the pressing block, and the pressing block is used to press the first vacuum suction plate.

[0011] By adopting the above technical solution, when the first cylinder starts, it drives the moving plate to descend. The descending of the moving plate drives the pressing block to descend, and the descending of the pressing block drives the first vacuum suction plate to descend, causing the middle position on the lower side of the packaging bag to descend driven by the first vacuum suction plate, creating a certain gap inside the packaging bag. This facilitates the uniform arrangement of peanuts during the vibration process of peanuts and improves the stability of the device during use.

[0012] Optionally, the air extraction assembly includes a first hydraulic cylinder, a bag-opening member, a vacuum pump, a connecting pipe, and a vacuum suction nozzle. The vacuum pump is located at the upper end of the machine body, and the vacuum pump is slidably connected to the machine body horizontally. The connecting pipe is located on one side of the vacuum pump and is connected to the vacuum pump. The first hydraulic cylinder is fixedly provided at the upper end of the machine body, and the output end of the first hydraulic cylinder is fixedly connected to the vacuum pump. The bag-opening member is located at the upper end of the placement table, and the bag-opening member is used to open the mouth of the packaging bag.

[0013] By adopting the above technical solution, the bag-opening member opens the mouth of the packaging bag. When the first hydraulic cylinder starts, it drives the vacuum pump to move horizontally. The horizontal movement of the vacuum pump drives the connecting pipe to move horizontally, and the horizontal movement of the connecting pipe drives the vacuum suction nozzle to move horizontally. This enables the vacuum suction nozzle to enter the packaging bag, and then the vacuum pump starts to extract the air inside the packaging bag, improving the moisture-proof effect of the packaging device.

[0014] Optionally, a filter screen is fixedly provided inside the connecting pipe. An opening is provided at one end of the connecting pipe close to the vacuum suction nozzle, and a collection box is provided at the opening. The collection box is threadedly connected to the connecting pipe. A baffle is fixedly provided inside the connecting pipe, and the baffle is inclined downward from top to bottom towards the direction close to the vacuum suction nozzle.

[0015] By adopting the above technical solution, the filter screen filters the impurities entering the connecting pipe during the extraction process, reducing the probability of damage to the vacuum pump caused by impurities entering the vacuum pump. The collection box collects the impurities. The inclined design of the baffle helps to guide the impurities towards the collection box, reducing the residue of impurities inside the connecting pipe and simultaneously reducing the probability of impurities re-entering the vacuum suction nozzle, extending the service life of the device.

The second cylinder is fixedly provided at the upper end of the placement table. The connecting plate is coaxially fixed to the output end of the second cylinder. The second vacuum suction plate is fixedly provided at the lower end of the connecting plate.

[0017] By adopting the above technical solution, when the second cylinder starts, it drives the connecting plate to descend. The descending of the connecting plate drives the second vacuum suction plate to descend to adsorb the upper surface of the packaging bag, opening the mouth of the packaging bag, facilitating the entry of the vacuum suction nozzle into the packaging bag to extract the air inside the packaging bag, and improving the convenience of use of the sealing device.

[0018] Optionally, the thermoplastic component includes a second hydraulic cylinder, a fixing plate, a pressing block, a thermoplastic plate, and a fourth elastic member.

The pressing block is located at the lower end of the fixing plate. The fourth elastic member is fixed between the fixing plate and the pressing block.

[0019] By adopting the above technical solution, when the second hydraulic cylinder starts, it drives the fixing plate to descend. The descent of the fixing plate drives the pressing block and the thermoplastic plate to descend simultaneously. After the pressing block descends to contact the packaging bag, it presses the packaging bag. The fixing plate continues to descend, compressing the fourth elastic member. Then the thermoplastic plate contacts the packaging bag to seal the packaging bag, improving the firmness and tightness of the seal and reducing the probability of peanuts getting damp.

[0020] Optionally, the moving component includes a second motor, an intermittent wheel set, and several connecting rods. The second motor is fixed to the upper end of the frame. The intermittent wheel set is coaxially fixed to the output shaft of the second motor. The several connecting rods are fixed to the intermittent wheel set.

One end of the connecting rod away from the intermittent wheel set is fixedly connected to the corresponding first vacuum suction plate.

[0021] By adopting the above technical solution, when the second motor starts, it drives the intermittent wheel set to rotate. The rotation of the intermittent wheel set drives the connecting rods to rotate. The rotation of the connecting rods drives the first vacuum suction plate to rotate. The first vacuum suction plate drives the packaging bag to slide, facilitating subsequent operations and improving the stability of the device during use.

The rack is fixed to the inner side of the lifting plate and meshes with the gear. The third vacuum suction plate is fixed to the lower end of the lifting plate.

[0023] By adopting the above technical solution, when the third motor starts, it drives the gear to rotate. The rotation of the gear drives the rack to lift and lower. The lifting and lowering of the rack drive the lifting plate to lift and lower. The lifting and lowering of the lifting plate drive the third vacuum suction plate to lift and lower, enabling the third vacuum suction plate to adsorb the upper surface of the packaging bag, facilitating the even arrangement of peanuts during the vibration process and improving the stability of the device during use.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the motor starts, it drives the rotating rod to rotate. The rotation of the rotating rod drives the telescopic rod to move upward and strike the vibrating plate, causing the vibrating plate to rotate. The vibration of the rotating plate drives the vibration of the vacuum suction plate 1, and the vibration of the vacuum suction plate 1 drives the vibration of the peanuts in the packaging bag, making the peanuts evenly distributed in the packaging bag. The air extraction component starts to extract the air in the packaging bag, and then the thermoplastic component seals the packaging bag. Since the peanuts are evenly distributed in the packaging bag, the vacuum degree of the packaging bag after air extraction is evenly distributed, reducing the probability of the packaging bag bulging after air extraction and improving the sealing quality of the peanuts. 2. When the hydraulic cylinder 2 starts, it drives the fixed plate to descend. The descent of the fixed plate drives the pressing block and the thermoplastic plate to descend simultaneously. After the pressing block descends and contacts the packaging bag, it presses the packaging bag.

When the cylinder 2 starts, it drives the connecting plate to descend. The descent of the connecting plate drives the vacuum suction plate 2 to descend to adsorb the upper end face of the packaging bag, opening the opening of the packaging bag, facilitating the vacuum suction nozzle to enter the packaging bag to extract the air in the packaging bag, and improving the convenience of using the sealing device.

[0033] The embodiment of the present application discloses a fully automatic anti-moisture sealing device for peanuts. Embodiment

[0034] Referring to Figure 1 and Figure 2 A fully automatic anti-moisture sealing device for peanuts includes a machine body 1. A placing table 11 is fixedly arranged at the upper end of the machine body 1. A circular rail 12 is arranged at the upper end of the placing table 11. A plurality of first vacuum suction plates 13 are arranged at the circular rail 12. The plurality of first vacuum suction plates 13 are all slidably connected to the circular rail 12 along the length direction of the circular rail 12. The packaging bag 2 is placed on the first vacuum suction plates 13. A moving assembly 14 is arranged at the upper end of the frame.

[0035] Referring to Figure 2 and Figure 3, the moving component 14 includes a second motor 141, a connecting rod, a disc, and several connecting rods 142. The second motor 141 is fixedly arranged at the upper end of the frame. The connecting rod is coaxially fixed to the output end of the second motor 141. When the second motor 141 starts, it drives the connecting rod to rotate. The disc is provided with several grooves. When the connecting rod rotates to the grooves, it drives the disc to rotate. The several connecting rods 142 are fixedly arranged on the outer side of the disc and are arranged along the circumferential direction of the disc. When the disc rotates, it drives the connecting rods 142 to rotate. The connecting rods 142 correspond to the first vacuum suction plate 13 one by one. A first frame 131 is sleeved on the outer side of the first vacuum suction plate 13. An elastic member five 133 is fixedly arranged between the first frame 131 and the vacuum suction plate. A second frame 132 is sleeved on the outer side of the first frame 131. Slide rods 135 are fixedly arranged on both sides of the first frame 131. The slide rods 135 pass through the second frame 132 and are slidably connected to the second frame 132 in the vertical direction. An elastic member six 134 is fixedly arranged between the second frame 132 and the slide rods 135. The end of the connecting rod 142 away from the disc is fixedly connected to the second frame 132. When the connecting rod 142 rotates, it drives the second frame 132 to rotate. When the second frame 132 rotates, it drives the first frame 131 to rotate. When the first frame 131 rotates, it drives the first vacuum suction plate 13 to rotate.

[0036] Referring to Figure 3 and Figure 4 , a limiting component is arranged at the upper end of the placing table 11. The first vacuum suction plate 13 drives the packaging bag 2 to rotate to the limiting component. The limiting component includes a moving plate 112, a first cylinder 111, and two pressing blocks 113. The first cylinder 111 is fixedly arranged at the upper end of the placing table 11 and is vertically placed. The moving plate 112 is coaxially fixed to the output end of the first cylinder 111. When the first cylinder 111 starts, it drives the moving plate 112 to descend. The two pressing blocks 113 are respectively located on both sides of the moving plate 112. The pressing blocks 113 are slidably connected to the moving plate 112 in the vertical direction. An elastic member three 114 is fixedly arranged between the pressing blocks 113 and the moving plate 112. When the moving plate 112 descends, it drives the elastic member three 114 to descend. When the elastic member three 114 descends, it drives the two pressing blocks 113 to descend. The two pressing blocks 113 descend to press both ends of the packaging bag 2, reducing the probability of the packaging bag 2 moving during subsequent work. A pressing block 115 is fixedly arranged at the lower end of the moving plate 112. The pressing block 115 is located at the lower end of the pressing block 113. When the moving plate 112 descends, it drives the pressing block 115 and the pressing block 113 to descend.

[0037] Referring to Figure 4 , when the pressing block 113 descends to contact the packaging bag 2, it presses the packaging bag 2. At this time, the elastic member three 114 is compressed. The moving plate 112 drives the pressing block 115 to continue descending. When the pressing block 115 descends and contacts the first vacuum suction plate 13, it drives the first vacuum suction plate 13 to descend. The first vacuum suction plate 13 drives the middle position of the lower side of the packaging bag 2 to descend, creating a certain gap in the packaging bag 2, facilitating subsequent sorting of peanuts and improving the stability of the device.

[0038] Referring to Figure 4 , an adsorption assembly 18 is provided at the upper end of the placement table 11. The adsorption assembly 18 includes a lifting plate 181, a gear 182, a third motor 183, a third vacuum suction plate 184, and a rack 185. The third motor 183 is fixedly arranged at the upper end of the placement table 11. The gear 182 is coaxially fixed to the output shaft of the third motor 183. When the third motor 183 is started, it drives the gear 182 to rotate. The lifting plate 181 is located at the upper end of the placement table 11. The lifting plate 181 is hollow. The gear 182 is located inside the lifting plate 181. The rack 185 is fixedly arranged on the inner side of the lifting plate 181, and the rack 185 meshes with the gear 182. The rotation of the gear 182 drives the rack 185 to move up and down. The up and down movement of the rack 185 drives the lifting plate 181 to move up and down. The third vacuum suction plate 184 is fixedly arranged at the lower end of the lifting plate 181. The up and down movement of the lifting plate 181 realizes the up and down movement of the third vacuum suction plate 184, so that the third vacuum suction plate 184 adsorbs the upper end surface of the packaging bag 2, facilitating the subsequent uniform arrangement of peanuts and improving the convenience of using the device.

[0039] Referring to Figure 4 and Figure 5 , a first motor 151 is fixedly arranged at the upper end of the machine body 1. A rotating box 156 is fixedly arranged at the upper end of the machine body 1. A rotating rod 152 is rotatably connected inside the rotating box 156.

A telescopic rod 153 is vertically fixed to the rotating rod 152. The telescopic rod 153 is vertically placed. The rotation of the rotating rod 152 drives the telescopic rod 153 to move up and down. A vibrating plate 15 is provided at the end of the telescopic rod 153 away from the rotating rod 152. The telescopic rod 153 is inserted into the lower end of the vibrating plate 15. Two second elastic members 155 are fixedly arranged between the vibrating plate 15 and the rotating box 156. The two second elastic members 155 are respectively located on both sides of the vibrating plate 15. The second elastic members 155 are used to support the vibrating plate 15. An first elastic member 154 is arranged between the telescopic rod 153 and the vibrating plate 15. The up and down movement of the telescopic rod 153 collides with the vibrating plate 15 to generate vibration. The first elastic member 154 is used for buffering. The first vacuum suction plate 13 is located at the upper end of the vibrating plate 15. The vibration of the vibrating plate 15 drives the first vacuum suction plate 13 to vibrate, realizing the vibration of the peanuts in the packaging bag 2, making the peanuts evenly arranged in the packaging bag 2, reducing the probability of the occurrence of bulging after subsequent air extraction from the packaging bag 2, and improving the sealing quality of the peanuts.

[0040] Referring to Figure 4, after the peanuts are evenly arranged in the packaging bag 2, the vibrating plate 15 stops vibrating, the first vacuum suction plate 13 no longer sucks the lower end face of the packaging bag 2, the third vacuum suction plate 184 no longer sucks the upper end face of the packaging bag 2, the first cylinder 111 starts to drive the pressing block 113 to rise. A second cylinder 168 is fixedly arranged at the upper end of the placing table 11. A connecting plate is arranged at the output end of the second cylinder 168. The second cylinder 168 starts to drive the connecting plate to lift and lower. A second vacuum suction plate 169 is fixedly arranged at the lower end of the connecting plate. The lifting and lowering of the connecting plate drives the second vacuum suction plate 169 to lift and lower. The second vacuum suction plate 169 descends to suck the opening of the packaging bag 2 and opens the opening of the packaging bag 2. An air extraction assembly 16 is arranged at the upper end of the frame.

[0041] Refer to Figure 6 , the air extraction assembly 16 includes a first hydraulic cylinder 161, a vacuum pump 162, a connecting pipe 163 and a vacuum suction nozzle 164. The first hydraulic cylinder 161 is fixedly arranged at the upper end of the machine body 1. The vacuum pump 162 is located at the upper end of the machine body 1. The vacuum pump 162 is slidably connected to the machine body 1 in the horizontal direction. The output end of the first hydraulic cylinder 161 is fixedly connected to the vacuum pump 162. The first hydraulic cylinder 161 starts to drive the vacuum pump 162 to move horizontally. The connecting pipe 163 is located on one side of the vacuum pump 162. The connecting pipe 163 is connected to the vacuum pump 162. The horizontal movement of the vacuum pump 162 drives the connecting pipe 163 to move horizontally. The vacuum suction nozzle is located at the upper end of the placing table 11, and the vacuum suction nozzle is fixedly connected to the end of the connecting pipe far from the vacuum pump 162. The horizontal movement of the connecting pipe 163 drives the vacuum suction nozzle to move horizontally. The vacuum suction nozzle enters the packaging bag 2 from the opened opening of the packaging bag 2 to extract the air inside the packaging bag 2.

[0042] Refer to Figure 6 , a filter screen 166 is fixedly arranged inside the connecting pipe. During the process of extracting the air inside the packaging bag 2, impurities enter the connecting pipe from the vacuum suction nozzle. The filter screen 166 filters to reduce the probability of impurities entering the vacuum pump 162. An opening is provided at one end of the connecting pipe close to the vacuum suction nozzle 164. A collection box 165 is arranged at the opening. The collection box 165 collects the impurities. The collection box 165 is threadedly connected to the connecting pipe, which is convenient for the disassembly of the collection box 165 to pour out the impurities inside the collection box 165. A baffle 167 is fixedly arranged inside the connecting pipe. The baffle 167 inclines from top to bottom towards the direction close to the vacuum suction nozzle 164. The inclined design of the baffle 167 helps to guide the impurities towards the collection box 165, reduces the residue of impurities inside the connecting pipe, and at the same time reduces the probability of impurities re-entering the vacuum suction nozzle 164, prolonging the service life of the device.

[0043] Refer to Figure 7, a thermoplastic component 17 is provided at the upper end of the frame. After extracting the air in the packaging bag 2, the thermoplastic component 17 seals the packaging bag 2. The thermoplastic component 17 includes a second hydraulic cylinder 171, a fixing plate 172, a pressing block 173, a thermoplastic plate 174, and a fourth elastic member 175. The second hydraulic cylinder 171 is fixedly arranged at the upper end of the machine body 1, and the fixing plate 172 is coaxially fixed to the output end of the second hydraulic cylinder 171. When the second hydraulic cylinder 171 is started, it drives the pressing block 173 and the thermoplastic plate 174 to descend simultaneously. The thermoplastic plate 174 is fixedly arranged at the lower end of the fixing plate 172. The pressing block 173 is slidably connected to the thermoplastic block in the vertical direction. The pressing block 173 is located at the lower end of the fixing plate 172. The fourth elastic member 175 is fixedly arranged between the fixing plate 172 and the pressing block 173. When the pressing block 173 descends, it first contacts the packaging bag 2 and presses the packaging bag 2. Then the fixing plate 172 continues to descend. At this time, the fourth elastic member 175 is compressed. Then the thermoplastic plate 174 contacts the packaging bag 2 to seal the packaging bag 2, improving the firmness and tightness of the seal and reducing the probability of peanuts getting damp.

[0044] The implementation principle of a fully automatic anti-damp sealing device for peanuts in an embodiment of this application is as follows: The moving component 14 is started to drive the first vacuum suction plate 13 to rotate to the limiting component. The limiting component is started to press both ends of the packaging bag 2. The first motor 151 is started to drive the rotating rod 152 to rotate. The rotation of the rotating rod 152 drives the telescopic rod 153 to move up and down. The telescopic rod 153 moving up and down impacts the vibrating plate 15, further realizing the impact on the first vacuum suction plate 13 to generate vibration, thereby driving the peanuts in the packaging bag 2 to vibrate, making the peanuts evenly arranged in the packaging bag 2, reducing the probability of the occurrence of bulging after subsequent air extraction from the packaging bag 2, and improving the sealing quality of the peanuts.

[0045] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
