Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, and in particular to a packaging device for a carbon fiber prepreg packaging line. Background Technology

[0002] In existing carbon fiber prepreg packaging production lines, vacuum sealing equipment is crucial for ensuring the storage, moisture protection, and damage prevention of carbon fiber prepreg. However, most current vacuum sealing devices suffer from the following problems: Low production efficiency: Most are single-station designs, and feeding, packaging and unloading must be carried out in sequence. During the packaging operation, the equipment is in standby mode, the overall production pace is slow, and it is difficult to adapt to the needs of high-speed packaging lines. Unstable packaging quality: The fixing structure of the packaging bag is simple, and it is positioned by simply clamping or placing it. During the packaging process, the packaging bag is prone to displacement, which can lead to misalignment of the seal and leakage. Poor feeding accuracy: The feeding mechanism lacks a stable limiting and support structure, and the components are prone to shaking during the conveying process, making it difficult to accurately deliver the packaging bag to the sealing station and affecting the consistency of sealing. Summary of the Invention

Detailed Implementation

[0021] Please see Figures 1-4 ,in, Figure 1 This is a schematic diagram of the packaging device for a carbon fiber prepreg packaging line according to the present invention. Figure 2 yes Figure 1 Enlarged view of point A in the middle. Figure 3 This is a schematic diagram of the packaging device for a carbon fiber prepreg packaging line of the present invention from another direction. Figure 4 This is a schematic diagram of the structure of the inner cavity of the workbench of the present invention.

[0022] This invention provides a packaging device for a carbon fiber prepreg packaging line, including a vacuum packaging machine. Feeding mechanisms are respectively arranged on the left and right sides of the vacuum packaging machine. The vacuum packaging machine includes a worktable 101 with an internal cavity. The feeding mechanism includes a drive assembly disposed on the side wall of the cavity. A first rotating rod 106, horizontally penetrating the worktable 101, is driven at the output end of the drive assembly. First connecting rods 107, perpendicular to the axis of the first rotating rod 106, are respectively arranged at both ends of the first rotating rod 106. The first connecting rods 107 are located away from the first rotating rod 106. One end of the worktable is provided with a first rotating seat 108, and a placement component is provided between the two first rotating seats 108. The worktable 101 is also provided with a limiting component for limiting the movement of the placement component. The limiting component includes a second rotating rod 110 that runs horizontally through the worktable 101. The two ends of the rotating rod are respectively provided with a second connecting rod 111 perpendicular to the axis of the second rotating rod 110. The end of the second connecting rod 111 away from the second rotating rod 110 is provided with a second rotating seat 112. The two second rotating seats 112 are respectively provided at the two ends of the placement component.

[0023] In this embodiment, the workbench 101 is integrally formed from stainless steel, and the internal cavity 126 is adapted to the installation requirements of the drive components and transmission structure, ensuring that there is no interference in the operation of each component after installation, while improving the rigidity and stability of the overall structure and avoiding deformation that may affect the accuracy of operation during long-term use.

[0024] Furthermore, the vacuum packaging machine also includes two heat sealing strips 105 symmetrically arranged above the worktable 101, a fixed frame 102 is provided at the rear end of the worktable 101, a lifting module 103 is provided at the top of the fixed frame 102, and a sealing cover 104 located directly above the worktable 101 is provided at the output end of the lifting module 103.

[0025] In this embodiment, the heat-sealing strip 105 is fixed to the mounting groove on the top of the workbench 101 by bolts. Its heating surface is kept horizontal and precisely aligned with the through groove 115 of the mounting plate 114 to ensure that it can accurately act on the opening end of the packaging bag during heat sealing. The fixing frame 102 is made of carbon steel and welded to the rear end of the workbench 101 to ensure support strength. The lifting module 103 is driven by a cylinder and connected to the top of the fixing frame 102 through a flange. The edge of the sealing cover 104 is adapted to the sealing groove on the top of the mounting frame 113, which can effectively avoid air leakage after sealing and ensure the vacuum sealing effect.

[0026] Furthermore, the first connecting rod 107 and the second connecting rod 111 are of the same length and always remain parallel. The distance between the first rotating seat 108 and the second rotating seat 112 is the same as the distance between the first rotating rod 106 and the second rotating rod 110.

[0027] In this embodiment, both the first linkage 107 and the second linkage 111 are made of high-strength alloy material and have been treated with anti-rust coating to extend their service life. Both ends are fixed to the first rotating rod 106 and the second rotating rod 110 respectively by key connection to ensure that there is no loosening during transmission. Both the first rotating seat 108 and the second rotating seat 112 adopt deep groove ball bearing structure to reduce rotational friction when the placement component moves, ensure smooth operation of the parallelogram transmission structure, and keep the placement component moving in a horizontal state at all times.

[0028] Furthermore, the placement assembly includes a mounting frame 113 rotatably disposed between the two first rotating seats 108 and the two second rotating seats 112, a mounting plate 114 is disposed inside the mounting frame 113, and clamping kits are respectively disposed at the front and rear ends of the mounting plate 114.

[0029] In this embodiment, the mounting frame 113 is a rectangular frame structure with a lightweight design made of aluminum alloy, which ensures structural strength and facilitates movement, reducing the load on the drive components; the mounting plate 114 is fixed inside the mounting frame 113 by bolts, and the surface is treated with anti-slip to prevent the packaging bag from sliding after being placed; the installation position of the clamping kit corresponds to the position of the heat sealing strip 105, ensuring that the opening end of the packaging bag can be accurately aligned with the heat sealing strip 105 after being clamped, avoiding heat sealing misalignment.

[0030] Furthermore, the clamping kit includes a fixing seat 116 disposed at one end of the mounting plate 114. The fixing seat 116 has a concave surface 127 on its top. Pressure components are respectively disposed at the left and right ends of the mounting frame 113. The telescopic ends of the two pressure components are provided with an elongated pressure block 120 located directly above the fixing seat 116. The bottom of the pressure block 120 has a convex surface 128 that matches the concave surface 127.

[0031] In this embodiment, the fixing base 116 and the mounting plate 114 are integrally formed. The concave surface 127 has an arc-shaped structure that fits the contour of the opening end of the packaging bag, increasing the contact area. The pressure block 120 is made of wear-resistant rubber material to wrap the metal core. The curvature of the convex surface 128 and the concave surface 127 are perfectly matched. When clamped, it can ensure a firm fixation and avoid damage to the surface of the packaging bag from hard contact. It is especially suitable for easily damaged film packaging bags.

[0032] Furthermore, the pressure component includes a fixing plate 117 disposed at one end of the mounting frame 113, a moving rod 119 vertically slidably passing through the fixing plate 117, the bottom of the moving rod 119 being fixedly connected to the pressure block 120, and a return spring 118 sleeved on the outer wall of the moving rod 119 being disposed between the pressure block 120 and the fixing plate 117.

[0033] In this embodiment, the fixing plate 117 is vertically welded to the end of the mounting frame 113. The moving rod 119 adopts an optical axis design and is fitted with the sliding hole of the fixing plate 117 to ensure smooth up and down sliding without jamming. The reset spring 118 is a compression spring with an adapted elastic coefficient, which can provide sufficient clamping force to prevent the packaging bag from shifting, and also facilitates the operator to manually lift the pressure block 120 for feeding, balancing the convenience of operation and the stability of fixation.

[0034] Furthermore, the mounting plate 114 has through grooves 115 at its front and rear ends respectively, which are adapted to the heat sealing strip 105. When the mounting frame 113 contacts the workbench 101, the heat sealing strip 105 extends through the through grooves 115 to the top of the mounting plate 114.

[0035] In this embodiment, the width and length of the through groove 115 are adapted to the width and length of the heat sealing strip 105, respectively. When the mounting frame 113 is attached to the workbench 101, the top of the heat sealing strip 105 is a certain distance above the upper surface of the mounting plate 114 to ensure that it can fully contact the opening end of the packaging bag and apply appropriate pressure to ensure the sealing performance of the heat seal and avoid leakage due to insufficient contact.

[0036] Furthermore, the drive assembly includes a drive motor 121 disposed on the side wall of the inner cavity 126, the output end of the drive motor 121 is provided with a drive shaft 122, one end of the drive shaft 122 is provided with a drive gear 123, and the drive gear 123 is meshed with a driven gear 109 disposed on the first rotating rod 106.

[0037] In this embodiment, the drive motor 121 is fixed to the side wall of the inner cavity 126 by a motor mount to ensure no severe vibration during operation; the drive shaft 122 is connected to the output end of the drive motor 121 via a coupling, making the transmission more stable; both the driving gear 123 and the driven gear 109 adopt a helical gear design, which has high meshing accuracy, smooth transmission, reduces noise during operation, and reduces gear wear, extending the service life of the transmission components. The drive motor 121 is a servo motor. The servo motor can achieve precise angular displacement control through pulse signals, and the servo motor supports rapid start and stop without significant inertial overshoot. When starting, it can quickly reach the set speed, and when stopping, it can immediately lock the output shaft to ensure that the first linkage 107 stops immediately after rotating to the designated position, without continuing to rotate due to inertia, thus ensuring the stability of the feeding mechanism.

[0038] Furthermore, the diameter of the driving gear 123 is smaller than the diameter of the driven gear 109.

[0039] In this embodiment, the driving gear 123 and the driven gear 109 are designed with different diameters to form a speed reduction transmission, which increases the output torque and ensures that the drive component can smoothly drive the placement component to move. Even if the placement component carries a lot of packaging bags, it can avoid transmission failure or jamming due to excessive load, thus ensuring the stability of equipment operation.

[0040] Furthermore, support components are respectively provided at both ends of the workbench 101. The support components include an F-shaped support frame 124 provided at one end of the workbench 101, and two pulleys 125 are provided above the support frame 124 for auxiliary support of the mounting plate 114.

[0041] In this embodiment, the support frame 124 is made of carbon steel welded and fixed to the ground at the bottom by expansion bolts to ensure stable support without shaking; the pulley 125 is made of polyurethane rollers with a smooth and wear-resistant surface, and its top height is flush with the upper surface of the workbench 101 to ensure a smooth transition when the components are moved, avoiding the displacement of the packaging bag or the tilting of the mounting plate 114 due to height differences, and improving the stability of the feeding process.

[0042] Working principle: In the initial state, the placement component of one feeding mechanism is located at the loading station outside the workbench 101, and the placement component of the other feeding mechanism is located at the sealing station above the workbench 101. The sealing cover 104 is in the raised state, and the heat sealing strip 105 is in the power-off cooling state. The operator neatly places multiple packaging bags on the mounting plate 114 at the loading station, lays the open end of each packaging bag flat on the concave surface 127 of the fixed base 116, and manually pulls the pressure block 120 upward. The moving rod 119 moves upward along the fixed plate 117. The return spring 118 is compressed. After the opening end of the packaging bag is placed in place, the pressure block 120 is released. The return spring 118 returns to its original position and pushes the pressure block 120 downward. The convex surface 128 and the concave surface 127 fit together, firmly clamping the opening end of the packaging bag. After the sealing station operation is completed, the drive motor 121 of the feeding mechanism on this side is started. The drive shaft 122 drives the drive gear 123 to rotate. The drive gear 123 drives the driven gear 109 and the first rotating rod 106 to rotate synchronously. The first connecting rod 107 and the second connecting rod 111 swing in parallel, driving... The placement component moves to the outside of the workbench 101 to the unloading station; simultaneously, the feeding mechanism drive motor 121 of the loading station starts, driving the placement component that has been loaded to move smoothly above the workbench 101. At this time, the bottom of the mounting frame 113 is in contact with the upper surface of the workbench 101, and the heat sealing strip 105 extends through the through groove 115 to the top of the mounting plate 114; the lifting module 103 starts, pushing the sealing cover 104 down to seal and fit with the top of the mounting frame 113 to form a sealed space; the vacuum packaging machine starts the vacuuming operation, waiting for the vacuum inside the cavity to be fully evacuated. Once the vacuum level reaches the set value, the heat sealing strip 105 is energized and heated to the set temperature to heat seal the opening of the packaging bag. The heat sealing time is maintained within a suitable range. After heat sealing, the heat sealing strip 105 is de-energized and cooled down. The vacuum packaging machine stops vacuuming and releases pressure. The lifting module 103 drives the sealing cover 104 to rise and reset. At the same time, the sealed placement component is moved out of the workbench 101, and the operator removes the sealed product. The placement component that has been loaded on the other side moves synchronously to the sealing station. The above process is repeated to achieve continuous operation of the dual workstations.

[0043] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
