Description

Technical Field

[0001] This application relates to the field of packaging equipment technology, and in particular to a high-efficiency vacuum packaging device. Background Technology

[0002] Vacuum packaging of tea is a crucial step in modern food processing, playing a vital role in maintaining freshness and extending shelf life. Traditional tea vacuum packaging equipment often operates on a single-station model, meaning it can only vacuum-pack a single bag at a time. While this type of equipment meets basic sealing requirements, it falls short in large-scale production and highly automated production lines. In recent years, with the increasing market demand for high-quality tea products, efficient and energy-saving tea vacuum packaging equipment has become a research hotspot.

[0003] Currently, common vacuum packaging methods for tea mainly include manual vacuum sealing machines and semi-automatic continuous vacuum sealing machines. Manual vacuum sealing machines typically require an operator to place the packaged tea bags into the machine, start the vacuuming device, and then heat-seal the bags after vacuuming. This method is simple and easy to implement, but it requires high manual intervention, has low production efficiency, and is difficult to adapt to the needs of mass production. Semi-automatic continuous vacuum sealing machines use conveyor belts to transport the packaging bags sequentially to the vacuuming area, achieving a certain degree of continuous operation. However, each bag still needs to be processed individually, which cannot significantly improve production speed, and it also consumes more energy.

[0004] However, these traditional methods have revealed significant shortcomings in practical applications. Especially for products like tea, which require large batches and stringent quality control, the existing method of vacuuming each bag individually is not only time-consuming and labor-intensive but also energy-intensive and inefficient, severely impacting the economic benefits and competitiveness of enterprises. Therefore, developing a highly efficient vacuum packaging device for tea that can process multiple bags simultaneously has become an urgent technical problem to be solved. Summary of the Invention

[0005] To address the aforementioned problems, this application provides a high-efficiency vacuum packaging device.

[0006] This application provides a high-efficiency vacuum packaging device, which adopts the following technical solution: A high-efficiency vacuum packaging device includes a shaking tray, a weighing mechanism, a packaging mechanism, and a vacuum mechanism. The vacuum mechanism includes a conveyor table and a vacuum machine. The conveyor table includes a conveyor frame, on which a conveyor belt and conveyor rollers are mounted. A guide rod is fixedly mounted on the conveyor frame near the conveyor rollers. The guide rod is connected to a fixed plate.

[0007] By adopting the above technical solutions, this tea vacuum packaging equipment can achieve continuous vacuuming of tea bags. The combined use of the shaking tray and weighing mechanism ensures accurate and consistent weight for each batch of tea, guaranteeing precise tea quality in each tea bag. The conveyor design allows multiple tea bags to be transported to the vacuum machine simultaneously, improving work efficiency. The guide rods ensure the stability and accurate positioning of the tea bags during transport, avoiding vacuuming failures or poor sealing due to positional misalignment. The combined design of the vacuum tube, sealing ring, and heating strip within the mold housing enables efficient vacuuming and sealing operations to be completed in a short time, further improving production efficiency and energy utilization efficiency.

[0008] Preferably, a gate and a gate cylinder are provided at the end of the conveyor frame near the conveyor roller.

[0009] By adopting the above technical solution, the gate and gate cylinder settings can effectively control the timing of tea bags being delivered from the conveyor, thereby improving the equipment's operational stability and production efficiency. Simultaneously, the gate cylinder can respond quickly, achieving precise opening and closing actions, avoiding interference between packaged and unpackaged tea bags, further enhancing the overall efficiency of the production line.

[0010] Preferably, a counting sensor is also fixedly installed on the conveyor frame.

[0011] By adopting the above technical solution, automatic counting can be achieved during the vacuum packaging process of tea, ensuring the accuracy of the quantity of each batch of tea and improving the automation level and management efficiency of the production process. The counting sensor allows operators to monitor the number of tea bags in real time, avoiding errors caused by manual counting.

[0012] Preferably, the weighing mechanism includes a weighing plate, a weighing sensor is fixedly installed at the bottom of the weighing plate, a moving tube is provided between the weighing plate and the shaking disc, the moving tube is located below the shaking disc, the moving tube includes a funnel tube section, a straight tube section and a flared tube section arranged from top to bottom, the narrow end face of the funnel tube section and the flared tube section is fixedly connected to the straight tube section, and the weighing plate is located below the flared tube section.

[0013] By adopting the above technical solution, this weighing mechanism can accurately weigh tea leaves, improving the automation and accuracy of the production process. The weighing plate, used in conjunction with a load cell, can accurately detect the weight of the tea leaves in real time, ensuring consistent weight within each packaging bag. The design of the funnel-shaped tube, straight tube, and flared tube allows for smooth transfer of tea leaves from the shaking tray to the weighing plate, reducing jamming and improving work efficiency. The flared tube design not only facilitates even distribution of the tea leaves but also reduces loss due to friction during transport.

[0014] Preferably, the transverse interfaces at any position of the funnel tube section, the straight tube section, and the flared tube section are all circular, the shape of the weighing plate is matched with the shape of the flared tube section, and the lower end face of the flared tube section is fixed with bristles by Velcro, the bristles being in contact with the top of the weighing plate.

[0015] By adopting the above technical solution, the horizontal interfaces of the funnel tube, straight tube, and flared tube are all circular, making the tea leaves move more smoothly, reducing the possibility of blockage, and improving the efficiency of the equipment. The shape of the weighing plate matches the shape of the flared tube, ensuring the accuracy and stability of the weighing. Brush bristles are fixed to the lower end face of the flared tube with Velcro, and the bristles contact the top of the weighing plate, effectively preventing tea leaves from remaining on the weighing plate surface, further ensuring weighing accuracy, and facilitating cleaning and maintenance.

[0016] Preferably, the weighing mechanism further includes a lead screw drive assembly, which includes a threaded block and is fixedly connected to the straight pipe section.

[0017] By adopting the above technical solution, precise control and adjustment of the weighing mechanism can be achieved. Specifically, the screw drive assembly allows the straight tube section to move laterally, thereby adjusting the distance between the funnel tube section and the weighing plate, ensuring the uniformity and accuracy of the tea leaves entering the weighing plate, and improving weighing precision. At the same time, this adjustable structure also facilitates adjustments based on the feeding of different batches of tea leaves, enhancing the flexibility and applicability of the equipment.

[0018] Preferably, one end of the shaking disc has a narrowed outlet, and a vibration motor is installed at the bottom of the shaking disc.

[0019] By adopting the above technical solutions, the uniform distribution of tea leaves and their rapid entry into subsequent processes can be effectively improved. The narrowed outlet design allows the tea leaves to be discharged more concentratedly during the shaking process, avoiding uneven scattering and improving the accuracy of subsequent weighing. The installation of the vibrating motor can effectively vibrate the shaking disc, keeping the tea leaves in a dynamic flow state on the disc, further ensuring the uniform distribution of the tea leaves, while also accelerating the speed at which the tea leaves move from the shaking disc to the moving tube, thus improving the efficiency of the entire packaging process.

[0020] Preferably, the packaging mechanism includes a mounting plate, which is disposed at the bottom of the weighing mechanism. A connecting rod is fixedly disposed below the mounting plate, and a bag conveying roller is rotatably mounted on the end of the connecting rod away from the mounting plate. A bag feeding assembly is disposed on the top of the bag conveying roller, and the bag feeding assembly includes a fixed vertical plate, on which a bag opening suction cup is vertically disposed.

[0021] By adopting the above technical solution, this tea vacuum packaging equipment can achieve efficient and continuous tea bag conveying and opening operations.

[0022] Preferably, the bag feeding assembly further includes an electric slide table, which includes a movable platform. A slide plate is fixedly mounted on the movable platform, and the slide plate is positioned toward the bag conveying roller. Multiple pull suction cups are fixedly mounted on the slide plate. A pull cylinder is also fixedly mounted on the movable platform, and the output shaft of the pull cylinder is fixedly connected to the slide plate.

[0023] By adopting the above technical solution, this tea vacuum packaging equipment can automate the bag feeding and pulling process. The use of an electric slide table allows the slide to move precisely in the vertical direction, and in conjunction with the pulling suction cup, it can effectively pull the bag open, thereby improving the efficiency and reliability of the entire packaging process.

[0024] Preferably, the packaging mechanism further includes a guide tube, which is disposed above the conveyor table, and the top of the guide tube is provided with a flared portion.

[0025] By adopting the above technical solutions, the tea vacuum packaging equipment can continuously and efficiently complete the packaging and vacuuming process of tea. The feed guide pipe is positioned above the conveyor table to ensure that the tea leaves can smoothly enter the packaging bag during transport, avoiding packaging defects caused by material accumulation or uneven distribution. The flared design increases the feeding area, further improving the flow rate and uniformity of the tea leaves, reducing the risk of blockage, and enhancing overall production efficiency.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a conveyor and a vacuum machine, multiple tea packaging bags can be vacuumed simultaneously, which greatly improves production efficiency and reduces energy consumption; 2. The guide rod design ensures stable operation of the conveyor rollers, guaranteeing the stability and accurate positioning of the tea bags during the conveying process, and avoiding problems such as vacuuming failure or poor sealing caused by positional deviation. 3.

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] In the description of the invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the invention.

[0031] This application discloses a high-efficiency vacuum packaging device, referring to... Figure 1 and Figure 3 It includes a shaking tray 1, a weighing mechanism, a packaging mechanism, and a vacuum mechanism. The vacuum mechanism includes a conveyor table and a vacuum machine.

[0032] Reference Figure 1 and Figure 2 The shaking tray 1 has a narrowed outlet at one end, and a vibration motor 11 is installed at the bottom of the shaking tray 1. The vibration motor 11 is used to drive the shaking tray 1 to shake. The shaking tray 1 is used to store tea leaves. When the shaking tray shakes, the tea leaves can be shaken out from the narrowed outlet. The shaking makes the tea leaves discharge evenly, which is convenient for subsequent weight replenishment.

[0033] The weighing mechanism includes a weighing plate 21, and a weighing sensor is fixedly installed at the bottom of the weighing plate 21. A moving tube 22 is provided between the weighing plate 21 and the shaking disc 1. The moving tube 22 is located below the shaking disc 1 and includes a funnel tube section 221, a straight tube section 222, and a flared tube section 223 arranged from top to bottom. The narrow end faces of the funnel tube section 221 and the flared tube section 223 are fixedly connected to the straight tube section 222. The weighing plate 21 is located below the flared tube section 223. The flared tube section 223 and the funnel tube section 221 are designed for better receiving and weighing of tea leaves. Specifically, the horizontal interfaces of any position in the funnel tube section 221, the straight tube section 222, and the flared tube section 223 are circular. The shape of the weighing plate 21 matches the shape of the flared tube section 223. Tea leaves shaken off the shaking tray 1 are received by the funnel-shaped funnel tube section 221 and fall onto the weighing plate 21 sequentially through the straight tube section 222 and the flared tube section 223 for weighing. During weighing, the inverted funnel-shaped flared tube section 223 can limit the tea leaves, allowing them to accumulate on the weighing plate 21, while the inverted funnel shape of the flared tube section 223 does not affect the accuracy of the weighing.

[0034] The lower end face of the flared tube section 223 is fixedly provided with bristles via Velcro, and the bristles contact the top of the weighing plate 21. The weighing mechanism also includes a screw drive assembly, which includes a threaded block fixedly connected to the straight tube section 222. The drive assembly drives the moving tube 22 to move as a whole. During the movement, the bristles on the lower end face of the flared tube section 223 move, brushing the tea leaves off the weighing plate 21. The packaging mechanism also includes a guide tube 32, which is located above the conveyor table. The top of the guide tube 32 is provided with a flared section 33, through which the tea leaves falling from the weighing plate 21 are guided downwards.

[0035] The packaging mechanism includes a mounting plate 31, which is located at the bottom of the weighing mechanism. A connecting rod 311 is fixedly installed below the mounting plate 31. A bag conveying roller 312 is rotatably installed at the end of the connecting rod 311 away from the mounting plate 31. The bag conveying roller 312 is used to feed tea packaging bags.

[0036] A bag feeding assembly is provided at the top of the bag conveyor roller 312. The bag feeding assembly includes a fixed vertical plate 328, on which a bag-opening suction cup 329 is vertically mounted. The bag feeding assembly also includes an electric slide table 324, which includes a moving stage 325. A slide plate 326 is fixedly mounted on the moving stage 325, facing the bag conveyor roller 312. Multiple pull suction cups 322 are fixedly mounted on the slide plate 326. A pull cylinder 323 is also fixedly mounted on the moving stage 325, and the output shaft of the pull cylinder 323 is fixedly connected to the slide plate 326. The bag conveyor roller 312 at the bottom feeds the packaging bag to the bottom of the bag feeding assembly and keeps the packaging bag in an upright position. The electric slide 324 drives the moving stage 325 to move near the packaging table. The pull cylinder 323 pushes the slide plate 326 to extend, causing the pull suction cup 322 to adsorb the packaging bag. Then, the pull cylinder 323 drives the slide plate 326 to retract. The electric slide 324 drives the moving stage 325 to move upward and align with the bag opening suction cup 329. The pull cylinder 323 drives the slide plate 326 to extend, causing the bag opening suction cup 329 to adsorb the other end of the packaging bag. The pull cylinder 323 drives the slide plate 326 to retract, opening the packaging bag and aligning the bag opening with the bottom of the guide tube 32. The tea leaves are guided into the packaging bag through the guide tube 32.

[0037] Reference Figure 4 and Figure 5The conveyor table is designed to transport multiple products simultaneously. It includes a conveyor frame 47, on which a conveyor belt 43 and conveyor rollers 42 are mounted. The conveyor belt 43 and conveyor rollers 42 are driven by a conventional drive device. The conveyor belt 43 and conveyor rollers 42 are distributed sequentially on the conveyor frame 47 according to the conveying direction. Guide rods 41 are fixedly mounted on the conveyor frame 47 near the conveyor rollers 42. The guide rods 41 are connected to a fixed plate; specifically, two guide rods 41 are arranged opposite each other. The two guide rods 41 are narrowed towards the end away from the conveyor belt 43, limiting the products as they move along the guide rods 41 and causing them to converge towards the center. The length of the guide rods 41 is set according to processing needs. Multiple products can be arranged sequentially between the two guide rods 41 simultaneously, facilitating simultaneous vacuum packaging by the vacuum machine. The vacuum machine is positioned above the conveyor rollers 42 and also above the guide rods 41. The guide rods 41 not only guide the products but also position the vacuum machine. The vacuum machine includes two opposing mold-closing housings 52, which are closed by a cylinder. The bottom of the mold-closing housings 52 is close to the top of the guide rod 41. A vacuum extraction tube 53 is fixedly installed inside the mold-closing housing 52. A sealing ring 54 and a heating strip 55 are arranged sequentially below the vacuum extraction tube 53. The lengths of the sealing strip and the heating strip 55 are matched with the lengths of the guide rod 41, so that products between the two guide rods 41 can be processed by the vacuum machine simultaneously. When the vacuum machine is started, the sealing strip and the heating strip 55 simultaneously clamp the bag opening of the packaging tape to seal the bag opening. The vacuum extraction tube 53 evacuates the bag opening through an externally connected vacuum pump. After the vacuuming is completed, the heating strip 55 heats the bag opening, causing the bag opening to melt and thus completing the seal.

[0038] A gate 44 and a gate cylinder are provided at the end of the conveyor frame 47 near the conveyor roller 42. The gate 44, in conjunction with the gate cylinder, forces the packaged product through the valve plate after vacuum packaging, using newly fed products. A counting sensor 45 is also fixedly installed on the conveyor frame 47. The counting sensor 45 counts the number of products on the guide rod 41 and controls the opening and closing of the valve and the timing of vacuum pumping based on the quantity information.

[0039] The implementation principle of this embodiment is as follows: After the equipment is started, the tea leaves to be packaged are shaken out by the shaking disc 1 and fall into the funnel tube section 221. The funnel tube section 221 guides the tea leaves to the straight tube section 222 and onto the weighing plate 21. The flared tube section 223 limits the tea leaves on the weighing plate 21, and the weighing plate 21 weighs the tea leaves. At the same time, the bag conveyor roller 312 feeds the packaging bag and pulls the bag opening open by the bag opening suction cup 329 and the pulling suction cup 322. The screw drive assembly drives the moving tube 22 to move, and the bristles at the bottom of the flared tube section 223 sweep the tea leaves onto the guide tube 32, through which the tea leaves are poured into the packaging bag. The conveyor table is located below the guide tube 32. The bag opening suction cup 329 and the pulling suction cup 322 simultaneously release the suction force on the packaging bag, and the packaged bag filled with tea leaves falls onto the conveyor table. The conveyor belt 43 transports the products to the guide rod 41. The number of products that have moved onto the guide rod 41 is recorded as the product passes the counting sensor 45. The top of the packaging bag narrows as it passes the guide rod 41, reducing the opening of the bag. The conveyor rollers 42 are designed to facilitate product slippage, causing the product that initially contacts the gate 44 to slip relative to the bottom conveyor rollers 42.

[0040] When the number of products on guide rod 41 reaches the predetermined quantity, the vacuum machine starts to first vacuum the packaging bag and then heat and seal it. This completes the packaging of the tea. Subsequently, the gate cylinder drives the gate 44 to open, and the products are driven by the conveyor roller 42 to be fed out.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
