Description

Technical Field

[0001] This utility model relates to the field of vacuum packaging equipment technology, specifically to a vertical vacuum heat sealing device. Background Technology

[0002] Vacuum packaging is widely used in industries such as food, pharmaceuticals, and 3C electronics due to its many advantages, including preventing product contamination, moisture protection, and extending shelf life. As the core component of vacuum packaging equipment, the performance of vacuum heat sealing devices directly affects the quality of the final product and work efficiency.

[0003] Currently, most vacuum packaging equipment used in the industry is horizontal. Traditional horizontal vacuum packaging machines have a large footprint. When dealing with tall or large materials, the equipment takes up a lot of space, and taller materials are prone to tilting, making them unsuitable for production lines in confined spaces. They also have low heat-sealing efficiency, requiring manual intervention to adjust the position of the packaging bags. For packaging bags of different sizes and lengths, horizontal vacuum packaging equipment requires timely manual adjustments, lacking self-adaptability and reducing packaging flexibility and equipment efficiency. Furthermore, the vacuum level is uneven between products, and the program-set delay time determines the vacuuming effect, making it impossible to monitor the true vacuum level inside the packaging bag, which affects product transportation and storage.

[0004] This shows that existing technologies still have certain shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a vertical vacuum heat sealing device that reduces the footprint of vacuum packaging equipment, improves the flexibility of vacuum packaging, and enhances work efficiency and product quality.

[0006] To achieve the above objectives, this utility model provides a vertical vacuum heat sealing device, comprising: The transfer gripper assembly is used to transfer the packaged bags containing the product from the bagging station to the vacuum heat sealing station; Heat-sealing assembly for heating and sealing the opening of a packaging bag; Vacuum sealing assembly, used to vacuum the inside of packaging bags; A heat-sealing lifting assembly is used to drive the heat-sealing sealing assembly to move up and down; The vacuum assembly includes a vacuum lifting cylinder fixing plate, a lifting slide cylinder, a vacuum pitch sliding base plate, a pitch rotary cylinder, a rotary cylinder disc, a connecting rod, a vacuum tube fixing plate, a vacuum pitch linear guide rail, a vacuum tube, and a negative pressure gauge. The heat-sealing lifting assembly includes a mounting base plate, a lifting cylinder, a second guide shaft, a second linear bearing, a solenoid valve, and a heat-sealing assembly fixing plate.

[0007] The above solution integrates four functional modules: transfer, vacuuming, heat sealing, and lifting, to create a vertically laid-out vacuum packaging solution. Compared to traditional horizontal equipment layouts, this significantly reduces the equipment's footprint, making it particularly suitable for confined production line spaces. Furthermore, vertical operation utilizes the material's gravity, making it naturally suitable for packaging fluid materials such as granules, powders, and liquids, thus improving the equipment's versatility and automation.

[0008] In a preferred embodiment of this application, the vacuum lifting cylinder fixing plate is fixed to the base plate of the vacuum assembly by bolts. The lifting slide cylinder serves as the power source for the lifting and lowering movement of the vacuum tube; The vacuum-evacuation variable-pitch sliding base plate is fixed to the lifting slide cylinder by bolts.

[0009] In the above solution, the fixing plate of the vacuum lifting cylinder is secured by bolts, ensuring the stability and reliability of the entire vacuum assembly installation and preventing vibration or displacement during high-speed operation. Using the lifting slide cylinder as a power source provides precise and efficient linear drive, guaranteeing the accuracy and repeatability of the vacuum tube lifting action.

[0010] In a preferred embodiment of this application, the rotary cylinder disc is connected to the variable pitch rotary cylinder by bolts; The vacuum tube fixing plate is connected to the rotary cylinder disc via a connecting rod.

[0011] In the above scheme, a variable pitch rotary cylinder is used to drive the rotary motion and combine it with a crank rocker mechanism to convert the rotary motion into linear motion. This structural design realizes the synchronous variable pitch action of the two vacuum tubes by driving with a single cylinder. The structure is compact, the control is simple, and it effectively reduces the complexity of the equipment and the manufacturing cost. At the same time, it can adaptively straighten the opening of packaging bags of different widths.

[0012] As a preferred embodiment of this application, the vacuum variable pitch linear guide rail is used to support and guide the vacuum tube fixing plate to perform reciprocating linear motion in a given direction. The vacuum tube is inserted into the packaging bag and moves to both sides under the drive of the variable pitch rotary cylinder.

[0013] In the above solution, the use of a vacuum-tuning linear guide ensures smooth and stable movement of the vacuum tube fixing plate and its vacuum tube during the pitch-changing process, resulting in low frictional resistance, high precision, and extended equipment lifespan. Driven by the pitch-changing cylinder, the vacuum tube moves to both sides, actively straightening and tightening the opening of the soft packaging bag, creating ideal conditions for subsequent sealing, greatly improving the success rate and quality of the seal, and preventing air leakage caused by bag opening wrinkles.

[0014] In a preferred embodiment of this application, the negative pressure gauge is connected to a vacuum tube for real-time monitoring of the vacuum level inside the packaging bag. The lifting slide cylinder drives the vacuum tube to extend and retract into or out of the packaging bag.

[0015] In the above solution, a negative pressure gauge can monitor the vacuum level inside the bag in real time, achieving closed-loop feedback control of the vacuum level. This overcomes the problem of inconsistent vacuum levels caused by bag size or leakage in traditional time-based control methods. It ensures that the vacuum level of each package consistently reaches the set value, greatly improving the uniformity and reliability of packaging quality and extending the product's shelf life.

[0016] In a preferred embodiment of this application, the heat-sealing assembly includes a heating blade and a sealing strip.

[0017] In the above solution, the combination of a heating blade and a sealing strip allows for immediate pressing and heating of the straightened bag opening after vacuuming, achieving seamless integration and efficient coordination between the vacuuming and heat-sealing processes. The sealing strip provides uniform pressure, while the heating blade provides precise heat, working together to form a strong and smooth sealing line, effectively preventing air leakage.

[0018] In a preferred embodiment of this application, the mounting base plate is connected to the frame by bolts; The lifting cylinder serves as the power source for lifting the heat-sealing assembly. The second guide shaft and the second linear bearing are used to support and guide the heat-sealing assembly fixing plate to reciprocate linearly in a given direction.

[0019] In the above solution, the heat-sealing lifting assembly is driven by a lifting cylinder and guided by a guide shaft and linear bearings, enabling precise and stable lifting of the entire heat-sealing assembly. This design ensures that the heat-sealing components can effectively avoid interference when the transfer grippers transport packaging bags, guaranteeing smooth continuous automated operation and is key to achieving high-speed cycle time.

[0020] In a preferred embodiment of this application, the solenoid valve is a cylinder control element; The heat-sealing assembly fixing plate is used to fix and install the heat-sealing assembly.

[0021] In the above solution, a solenoid valve is used to control the cylinder, achieving precise electrical and programmed control of the lifting and lowering motion of the heat-sealing assembly. This results in a fast response time and facilitates integration with the overall control system. The design of the heat-sealing assembly mounting plate makes the heat-sealing module easy to install, debug, and maintain, improving the maintainability of the equipment.

[0022] In a preferred embodiment of this application, the heat-sealing assembly and the vacuuming assembly are arranged vertically in a vertical direction to form a vertical layout. At least two vacuum tubes are provided, and the vacuum assembly also includes a vacuum tube fixing plate, wherein the vacuum tube is connected to the vacuum tube fixing plate. The variable-pitch rotary cylinder drives the vacuum tube to move in opposite directions or in opposite directions in the horizontal direction.

[0023] The above structure, with its vertical layout of the heat-sealing assembly and vacuum assembly, makes the equipment in this application highly adaptable to changes in product size (especially length). Only the height needs adjustment, while the length and width remain fixed, significantly saving production line layout space. For flowing materials, gravity allows for natural accumulation, eliminating the need for additional material handling or auxiliary forming fixtures, simplifying the process and reducing costs.

[0024] As a preferred embodiment of this application, it also includes a control system, which is electrically connected to the negative pressure gauge, the transfer gripper assembly, the heat-sealing assembly, the vacuum assembly, and the heat-sealing lifting assembly.

[0025] In the above solution, by real-time vacuum monitoring and feedback, combined with the linkage control of the control system, the overall packaging cycle time is increased to a high efficiency of 1200pcs / h, which meets the needs of modern large-scale automated production, while ensuring the stability and high quality of packaging.

[0030] like Figures 1-5 As shown, this application discloses a vertical vacuum heat-sealing device, which mainly consists of a frame and four parts mounted on the frame: a transfer gripper assembly 1, a heat-sealing assembly 2, a vacuum assembly 3, and a heat-sealing lifting assembly 4. By integrating four functional modules—transfer, vacuuming, heat sealing, and lifting—a vertically arranged vacuum packaging solution is constructed. Compared to the traditional horizontal equipment layout, it significantly reduces the equipment's footprint, making it particularly suitable for confined production line spaces. Simultaneously, vertical operation utilizes the material's gravity, naturally suited for packaging fluid materials such as granules, powders, and liquids, thus improving the equipment's versatility and automation level.

[0031] In one example, refer to Figure 2As shown, the transfer gripper assembly 1 includes a transfer linear guide rail 1-1, a transfer linear module 1-2, a transfer sliding base plate 1-3, a variable pitch linear guide rail 1-4, a variable pitch sliding base plate 1-5, a variable pitch synchronous belt 1-6, a variable pitch synchronous belt pressure plate 1-7, a gripper mounting bracket 1-8, a gripper cylinder 1-9, a cylinder connecting rod 1-10, a Z-type cylinder connecting plate 1-11, and a gear gripper 1-12. The transfer linear guide 1-1 is bolted to the frame and supports and guides the transfer sliding base plate 1-3 to reciprocate linearly in a given direction. The transfer linear module 1-2 is bolted to the frame and is driven by a servo motor to provide power and precise positioning for the forward and backward transfer movement of the transfer sliding base plate 1-3.

The variable pitch linear guide 1-4 is bolted to the transfer sliding base plate 1-3 and supports and guides the variable pitch sliding base plate 1-5 to reciprocate linearly in a given direction. The variable pitch sliding base plate 1-5 serves as the mounting plate for the gear gripper 1-12 and is bolted to the variable pitch linear guide 1-4.

The gripper cylinder 1-9 is the drive device for opening and closing the gear gripper, connected to the gear gripper 1-12 via the cylinder connecting rod 1-10 and the Z-type cylinder connecting plate 1-11. The gear gripper 1-12 consists of two opposing gripper fingers, driven by a cylinder through gear meshing. The opening and closing angle range of the gear gripper 1-12 is 0°-180°. The transfer gripper assembly 1 has two sets of devices, corresponding to two sets of heat-sealing vacuum devices.

[0032] Continue to refer to Figure 3As shown, the heat-sealing assembly 2 includes a heat-sealing triaxial cylinder 2-1, a heat-sealing triaxial cylinder 2-2, a sealing triaxial cylinder 2-3, a sealing triaxial cylinder 2-4, a cylinder connecting plate 2-5, a first guide shaft 2-6, a first linear bearing 2-7, a cylinder connecting plate 2-8, a heating blade 2-9, a sealing strip 2-10, and a sealing strip mounting plate 2-11. Specifically, heat-sealing triaxial cylinder 2-1 and heat-sealing triaxial cylinder 2-2 serve as the clamping power source for the heating blade 2-9. The two sets of cylinders are placed opposite each other, and the cylinder rods extend to clamp the heating blade 2-9 with the sealing strip 2-10. Sealing triaxial cylinders 2-3 and sealing triaxial cylinder 2-4 serve as the clamping power source for the sealing strip 2-10. The two sets of cylinders are placed opposite each other, and the cylinder rods extend to clamp the two sets of sealing strips 2-10. The cylinder connecting plate 2-5 connects the sealing strip mounting plate 2-11 into a single unit via the first guide shaft 2-6, which is then connected to the heat-sealing... Three-axis cylinder 2-2 and sealing three-axis cylinder 2-4 are connected and fixed to transmit the cylinder action and realize the clamping action of the device; the first linear bearing 2-7 is used to support and guide the first guide shaft 2-6 to perform reciprocating linear motion in a given direction; cylinder connecting plate 2-8 is connected and fixed to heat sealing three-axis cylinder 2-1 and sealing three-axis cylinder 2-3 respectively. The heating blade 2-9 and sealing strip 2-10 are driven by the above cylinders to move, realizing the clamping action. The heating blade 2-9 serves as a heat source for heat sealing the packaging bag to heat and melt the packaging bag to make it stick.

[0033] Furthermore, referring to Figure 4As shown, the vacuum assembly 3 includes a vacuum lifting cylinder fixing plate 3-1, a lifting slide cylinder 3-2, a vacuum pitch changing sliding base plate 3-3, a pitch changing rotary cylinder 3-4, a rotary cylinder disc 3-5, a connecting rod 3-6, a vacuum tube fixing plate 3-7, a vacuum pitch changing linear guide rail 3-8, a vacuum tube 3-9, and a negative pressure gauge 3-10.

The support and guide plate 3-7 of the vacuum tube makes a reciprocating linear motion in a given direction; the vacuum tube 3-9 is inserted into the packaging bag and moves to both sides under the drive of the variable pitch rotary cylinder 3-4, straightening the bag opening. The sealing strip 2-10 clamps and seals the bag opening. At this time, the vacuum pump starts automatically to remove the air from the packaging bag. The negative pressure gauge 3-10 is connected to the vacuum tube 3-9 to monitor the vacuum level in the packaging bag in real time. After the set value is reached, the lifting slide cylinder 3-2 retracts, pulling the vacuum tube 3-9 out of the packaging bag. The vacuum pump stops running. The heating blade 2-9 and the sealing strip 2-10 press the bag opening tightly. The heating blade 2-9 starts heating to melt and bond the bag opening, completing the vacuum heat sealing process.

[0035] Compared to the horizontal arrangement used in traditional equipment, the vertical arrangement of the heat-sealing component 2 and the vacuum component 3, combined with an adjustable clamping mechanism, allows the vertical vacuum heat-sealing device in this application to adapt to packaging bags and products of different lengths. Furthermore, due to gravity, the product automatically accumulates at the bottom of the packaging bag, eliminating the need for additional tooling for packaging fluid materials such as granules, powders, and liquids, thus improving packaging flexibility. For longer or taller materials, only the equipment height needs to be adjusted to allow sufficient packaging height; the equipment length and width remain unaffected, effectively reducing the equipment's footprint.

[0036] Furthermore, by using negative pressure gauges 3-10 in conjunction with the control system, the vacuum level inside the packaging bag can be monitored in real time without any waiting delay. Actual loading tests, conducted in conjunction with robotic bagging operations, have shown that the overall equipment cycle time can reach 1200 pieces per hour. This ensures the stability of the vacuuming effect, effectively preventing inconsistencies in packaging results between different products and improving overall packaging quality.
