Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, and in particular to an automated vacuum packaging equipment. Background Technology

[0002] In the food processing industry, vacuum sealing is a crucial process for ensuring product quality and extending shelf life. For example, bamboo shoot-flavored seasoned eggs, a unique snack combining the fresh aroma of bamboo shoots with the nutritional value of eggs, have seen continuous market demand growth due to their unique taste and convenient consumption. Their processing involves core steps such as raw material selection, bamboo shoot flavoring, cleaning and drying, and sealing for preservation. Among these, the sealing process is key to ensuring product quality and extending shelf life. Vacuum sealing technology is used to isolate the eggs from air, inhibit microbial growth, prevent oxidation and spoilage, and avoid flavor loss, while also preventing damage during transportation. The efficiency and timeliness of the sealing equipment directly affect the mass production capacity and the stability of the finished product quality.

[0003] However, existing food vacuum sealing equipment generally adopts a segmented operation mode of "bagging - centralized conveying - unified vacuum sealing," which means that the seasoned eggs that are put into the packaging bag later have to wait inside the bag for a long time for the previous products to be sealed. After the bamboo shoot flavored eggs are marinated, a small amount of seasoning juice and moisture remain on the surface, and the eggs themselves are rich in nutrients such as protein and fat, which are prone to oxidation when exposed to air. Excessive exposure time will significantly affect the product's freshness and quality consistency.

[0004] A search revealed a vacuum sealing packaging device with publication number CN114030675B. This device includes a conveying mechanism, a lifting mechanism, a sealing cover, a heat-sealing assembly, and a negative pressure mechanism. It works by feeding the packaging bag under the sealing cover, then the lifting mechanism drives the sealing cover down to form a closed cavity, followed by vacuuming and heat sealing. While this structure achieves automatic vacuum sealing, it uses a "bag-by-bag processing" method, meaning that one bag is sealed before the next is processed, failing to address the problem of products remaining inside the bag while waiting. For foods containing moisture and easily oxidized (such as bamboo shoot-flavored seasoned eggs), the products remain exposed to a non-vacuum environment for an extended period during the waiting process, making it difficult to effectively guarantee product freshness and flavor stability.

[0005] Therefore, the existing vacuum packaging equipment has shortcomings in its operational logic, and there is an urgent need to provide a solution that can reduce the exposure time of easily oxidized foods before packaging. Summary of the Invention

[0006] The purpose of this invention is to provide an automated vacuum packaging device to solve the problem mentioned in the background art that existing food products containing moisture and easily oxidized require a long time to wait in the bag for the preceding products to complete the packaging, resulting in excessive exposure time.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] An automated vacuum packaging device includes a conveying mechanism, a bagging mechanism, and a sealing mechanism. The conveying mechanism includes a base frame, on both sides of the upper end of which a first linear motor is fixedly mounted, and on the upper end of each of the first linear motors a second linear motor is fixedly mounted. The bagging mechanism includes a mounting frame, on both sides of the bottom end of which are respectively connected to one end of a pair of second linear motors. A material tray is slidably inserted into the upper end of the mounting frame, and a feeding bin is fixedly mounted at the bottom end of the material tray. The sealing mechanism includes a pair of fixed frames, on the bottom ends of which are respectively connected to the other ends of a pair of second linear motors. Movable blocks are slidably mounted on the opposing surfaces of the pair of fixed frames. First connecting frames and second connecting frames are fixedly mounted on both sides of the pair of movable blocks. Flexible pressure strips are slidably inserted into the opposing surfaces of the pair of first connecting frames, and heat pressing heads are slidably inserted into the opposing surfaces of the pair of second connecting frames.

[0009] Furthermore, a support frame is fixedly installed between the upper ends of the fixed frame, a movable frame is slidably inserted into the bottom end of the support frame, and a first pneumatic telescopic rod is installed at the top end of the support frame, with the output end of the first pneumatic telescopic rod fixedly connected to the top end of the movable frame.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the first pneumatic telescopic rod can drive the movable frame to slide along the support frame, realize the height adjustment of the movable frame, provide an adjustable operating space for subsequent air extraction operations, ensure that the air extraction needle can accurately connect with the packaging bag, and improve the flexibility of the air extraction operation before sealing.

[0011] Furthermore, a vacuum needle is fixedly installed at the bottom of the mobile frame, and a negative pressure connector is fixedly installed on one side of the mobile frame. One end of the negative pressure connector is connected to one end of the vacuum needle through a pipe.

[0012] The beneficial effects of adopting the above-mentioned further solution are that the negative pressure connector can be connected to an external negative pressure device, and the air extraction needle can be inserted into the packaging bag to extract air, thereby achieving vacuum treatment of the seasoned egg packaging bag, reducing the oxygen content in the packaging bag, extending the shelf life of the seasoned eggs, and ensuring the flatness of the package after sealing.

[0013] Furthermore, a second pneumatic telescopic rod is fixedly installed on the opposite sides of each of the first connecting frames, and the output end of the second pneumatic telescopic rod is fixedly connected to one side of the flexible pressure strip. A third pneumatic telescopic rod is fixedly installed on the opposite sides of each pair of the second connecting frames, and the output end of the third pneumatic telescopic rod is fixedly connected to one side of the hot pressure head. A fourth pneumatic telescopic rod is fixedly installed on the upper surface of each pair of the fixed frames, and the output end of the fourth pneumatic telescopic rod is fixedly connected to the top of the moving block.

[0014] The beneficial effects of adopting the above-mentioned further solution are that the second and third pneumatic telescopic rods can drive the flexible pressure strip and the hot pressure head to move respectively, realizing independent control of the pre-pressing and heat sealing actions. The fourth pneumatic telescopic rod can adjust the height of the moving block to adapt to the sealing requirements of different packaging bags. Each pneumatic telescopic rod has a fast driving response and controllable force, ensuring the accuracy and stability of the sealing operation.

[0015] Furthermore, the material tray is rotatably connected to a distribution tray, and the distribution tray has several material grooves circumferentially opened along its axis. The bottom end of the material tray is located at the bottom end of one of the material grooves, and a discharge groove is opened at the bottom end of the material groove.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the material trough on the material distribution plate can distribute the bamboo shoot flavored eggs. When the material distribution plate is rotated to align the material trough with the discharge trough, the seasoned eggs can be quantitatively fed, avoiding the situation of excessive or leaked material, and improving the accuracy and standardization of bagging.

[0017] Furthermore, a baffle is fixedly installed on the inner side of the material tray, and the bottom end of the baffle is rotatably connected to the upper center of the material distribution tray. A drive motor is fixedly installed on the upper end of the baffle, and the output end of the drive motor is connected to the material distribution tray for transmission.

[0018] The beneficial effect of adopting the above-mentioned further solution is that when the baffle rotates on the dispensing plate, it can sweep the flavored eggs into the material trough and avoid excess eggs on the material trough. The drive motor provides power for the rotation of the dispensing plate, realizes the automated control of dispensing and feeding, and ensures the continuity and stability of dispensing operations.

[0019] Furthermore, a fifth pneumatic telescopic rod is installed on both sides of the upper end of the mounting frame, and the output ends of a pair of fifth pneumatic telescopic rods are fixedly connected to the bottom sides of the material tray, respectively.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the fifth pneumatic telescopic rod can drive the material tray to rise and fall, adjust the distance between the feeding bin and the packaging bag, avoid damage to the seasoned eggs due to excessive drop during feeding, and adapt to the bagging needs of packaging bags of different heights, thereby improving the adaptability of the bagging operation.

[0021] Furthermore, the moving ends of the first linear motor and the second linear motor are both fixedly mounted with fixed plates, and three sixth pneumatic telescopic rods are fixedly mounted on the facing surfaces of each pair of fixed plates. The output ends of the sixth pneumatic telescopic rods are fitted with pneumatic grippers, and a conveyor frame is fixedly mounted on one end of the base frame.

[0022] The beneficial effects of adopting the above-mentioned further solution are that the first linear motor and the second linear motor work together to drive the fixed plate to move, the sixth pneumatic telescopic rod can adjust the extension distance of the pneumatic gripper, which makes it convenient to gather the two sides of the gripped packaging bag inward, increase the opening space, facilitate bag filling, and stretch the two sides of the packaging bag outward during sealing, which facilitates the heat press head to perform heat sealing. The pneumatic gripper can realize the gripping and transfer of the packaging bag, and the conveyor can transport the sealed finished product, realize the automated transfer of packaging bags between various workstations, and improve the continuity of the overall operation.

[0023] Furthermore, the conveying mechanism also includes a bracket located on one side of the mounting frame. The bottom ends of the bracket are respectively connected to the upper ends of a pair of second linear motors. A seventh electric telescopic rod is inserted into the center of the bracket, and a pressure block is fitted onto the output end of the seventh electric telescopic rod.

[0024] The beneficial effect of adopting the above-mentioned further solution is that the seventh electric telescopic rod can drive the pressing block to rise and fall. After the bagging is completed, the packaging bag moves to the bottom of the pressing block, and the pressing block presses down, which can press the flavored eggs inside the package to the bottom, making it convenient for subsequent sealing.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] This automated vacuum packaging equipment features a conveyor frame that provides a stable base for the entire system. A first and second linear motor work together to move the pneumatic grippers, facilitating the transport of packaging bags to the bottom of the corresponding bagging, sealing, and pressing mechanisms. The two sets of pneumatic grippers can grip the top and bottom of the packaging bags respectively, alternating their movement to transport the bags to the appropriate processing station. They can also work with the bag feeding mechanism to pick up new bags for sealing, adapting to the needs of different workstations. The bagging mechanism's tray stores bamboo shoot-flavored seasoned eggs, while the feeding hopper directs the eggs for pre-bag feeding. The sealing mechanism's flexible pressing strip pre-compresses the packaging bags, and a vacuum needle facilitates vacuuming inside the bags before heat sealing by the heat-pressing head. This overall structure automates the transport, bagging, and sealing of seasoned eggs, significantly improving processing efficiency and standardization. Attached Figure Description

[0044] As an embodiment of the present invention, a distributing tray 206 is rotatably connected inside the material tray 202. A plurality of material grooves 207 are circumferentially opened on the distributing tray 206 along its axis. A discharge groove 208 is opened at the bottom of one of the material grooves 207 at the bottom end of the material tray 202. The material grooves 207 on the distributing tray 206 can distribute bamboo shoot flavored eggs. When the distributing tray 206 is rotated so that the material grooves 207 and the discharge grooves 208 are aligned, the seasoned eggs can be quantitatively fed, avoiding the situation of excessive or leaked material, and improving the accuracy and standardization of bagging.

[0045] In one embodiment of the present invention, a baffle 203 is fixedly installed on the inner side of the material tray 202.

[0046] As an embodiment of the present invention, a fifth pneumatic telescopic rod 205 is installed on both sides of the upper end of the mounting frame 201. The output ends of a pair of fifth pneumatic telescopic rods 205 are fixedly connected to the bottom sides of the material tray 202 respectively. The fifth pneumatic telescopic rods 205 can drive the material tray 202 to rise and fall, adjust the distance between the feeding bin 209 and the packaging bag, avoid damage to the seasoned eggs due to excessive drop during feeding, and adapt to the bagging requirements of packaging bags of different heights, thereby improving the adaptability of the bagging operation.

[0047] As an embodiment of the present invention, the moving ends of the first linear motor 102 and the second linear motor 103 are both fixedly mounted with a fixing plate 107. Three sixth pneumatic telescopic rods 108 are fixedly mounted on the facing surfaces of each pair of fixing plates 107. The output ends of the sixth pneumatic telescopic rods 108 are all fitted with pneumatic grippers 109, that is, each of the three output ends of the sixth pneumatic telescopic rods 108 is connected to a pneumatic gripper 109. A conveyor frame 106 is fixedly installed at one end of the base frame 101. The first linear motor 102 and the second linear motor 103 work together to drive the fixed plate 107 to move. The sixth pneumatic telescopic rod 108 can adjust the telescopic distance of the pneumatic gripper 109, which makes it easy to gather the two sides of the gripped packaging bag inward, increase the opening space, and facilitate bagging. When sealing, it stretches the two sides of the packaging bag outward, which facilitates the heat press head 313 to perform heat sealing. The pneumatic gripper 109 can realize the gripping and transfer of the packaging bag. The conveyor frame 106 can transport the packaged finished product, realize the automated transfer of packaging bags between various workstations, and improve the continuity of the overall operation.

[0048] As an embodiment of the present invention, the conveying mechanism 1 further includes a bracket 104, which is located on one side of the mounting frame 201. The bottom ends of the bracket 104 are respectively connected to the upper ends of a pair of second linear motors 103. A seventh electric telescopic rod 105 is inserted into the center of the bracket 104. A pressure block 110 is fitted onto the output end of the seventh electric telescopic rod 105. The seventh electric telescopic rod 105 can drive the pressure block 110 to rise and fall. After the bagging is completed, the packaging bag moves to the bottom end of the pressure block 110. The pressure block 110 presses down, which can press the flavored eggs inside the package to the bottom end, making it convenient for subsequent packaging.

[0049] Specifically, the working principle of this automated vacuum packaging equipment is as follows: In use, the first linear motor 102 and the second linear motor 103 work together to move the fixed plate 107. The sixth pneumatic telescopic rod 108 adjusts the telescopic distance of the pneumatic gripper 109. The pneumatic gripper 109 picks up the new packaging bag and pulls its two sides inward to increase the opening, then moves it below the bagging mechanism 2. The fifth pneumatic telescopic rod 205 drives the material tray 202 to rise and fall, adjusting the distance between the material feeder 209 and the bag. The spacing between bags is controlled by the drive motor 204, which rotates the distributing tray 206. The baffle 203 sweeps the seasoned eggs from the tray 202 into the trough 207. When the trough 207 aligns with the discharge trough 208, the seasoned eggs are quantitatively dropped into the packaging bag via the feeding bin 209. After bagging, the pneumatic gripper 109 moves the packaging bag to below the support 104. The seventh electric telescopic rod 105 drives the pressing block 110 to press down, pressing the seasoned eggs in the packaging bag to the bottom. The packaging bag is then transferred to the sealing machine. At three points, pneumatic grippers 109 simultaneously stretch the two sides of the packaging bag outward to ensure a heat-sealing effect; the fourth pneumatic telescopic rod 307 adjusts the height of the moving block 308 to adapt to the packaging bag specifications; the first pneumatic telescopic rod 304 drives the moving frame 303 to descend, allowing the suction needle 306 to be inserted into the packaging bag; the second pneumatic telescopic rod 314 pushes the flexible pressure strip 312 to pre-tighten the opening of the packaging bag; the negative pressure connector 305 connects to an external negative pressure device to extract air from the bag using the suction needle 306; after the air extraction is completed, the suction needle 306... When the pressure bar 312 is raised, it continues to keep the packaging bag closed. At this time, the third pneumatic telescopic rod 309 pushes the hot pressure head 313 to heat seal the opening of the packaging bag. After the sealing is completed, the pneumatic gripper 109 is released and the finished product is output through the conveyor frame 106. Meanwhile, another set of pneumatic grippers 109 simultaneously picks up a new packaging bag for the next round of operation. The whole process realizes the automation of seasoned eggs bagging, quantitative bagging, compaction, vacuum sealing and finished product conveying, which greatly improves the processing and packaging efficiency and standardized quality.
