Description

Technical Field

[0001] This utility model relates to the field of packaging color printing technology, specifically to an ink dustproof box for packaging color printing. Background Technology

[0002] Packaging color printing usually refers to the color printing of packaging materials, a process widely used in many industries such as consumer goods, food and beverage, electronic products, cosmetics, and pharmaceuticals.

[0003] For example, patent application number 202420774268.X, published on the China Patent Network, is titled "A Dustproof Storage Box for Packaging Color Printing Ink." The box includes an ink container. The top of the ink container is equipped with a sealing component to enhance sealing performance. A lid is located on top of the sealing component. A through hole is formed on one side of the lid's top. A sealing gasket is located on top of the through hole. A scraper assembly for cleaning the inner wall of the ink container is located on top of the sealing gasket. This dustproof storage box for packaging color printing ink, through the sealing component, allows for connection to an external inflation device when transporting or handling the ink container. Gas is then injected into the air bladder, causing it to expand and fill the gap between the lid and the ink container, thus increasing the ink container's seal and preventing dust from entering during transport and handling, thereby improving the protection of the stored ink.

[0004] However, the sealing method of this storage box is relatively simple, mainly relying on the compression of airbags for sealing. However, the outer surface of the airbag itself has low friction, and the top of the tank does not have a limiting structure. Therefore, the airbag is prone to sliding displacement due to deformation after pressurization, which affects the sealing effect.

[0005] Therefore, it is necessary to redesign and modify the dustproof box for ink used in color printing of packaging. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a dustproof ink box for color printing packaging, which has the advantage of improving the sealing effect. It solves the problem that the sealing method of the storage box is relatively simple, mainly relying on the air bladder compression method for sealing. However, the outer surface of the air bladder itself has low friction, and the top of the can does not have a limiting structure. Therefore, the air bladder is prone to sliding displacement due to deformation after pressurization, which affects the sealing effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dustproof ink box for color printing packaging, comprising a can body; The top of the tank is provided with a cover plate, and the top of the cover plate is provided with a threaded sleeve through an adjustment structure. Both sides of the threaded sleeve are fixedly connected with claws. The side of the claws away from the threaded sleeve extends to the outside of the cover plate and is located outside the tank. The side of the claws away from the threaded sleeve contacts the surface of the tank. The adjustment structure can adjust the spacing of the claws and change the compression intensity.

[0008] As a preferred embodiment of this utility model, the adjustment structure includes a connecting frame fixedly connected to the top of the cover plate. A bidirectional screw is movably connected inside the connecting frame via a bearing. A screw sleeve is fitted onto the surface of the bidirectional screw and threadedly connected to the bidirectional screw. Both ends of the bidirectional screw extend through to the outside of the connecting frame and are fixedly connected to a rotating wheel.

[0009] As a preferred embodiment of the present invention, a guide strip is fixedly connected inside the connecting frame, and the guide strip extends into the interior of the threaded sleeve from the side away from the connecting frame and is slidably connected to the threaded sleeve.

[0010] As a preferred embodiment of this utility model, movable blocks are fixedly connected to both sides of the top of the cover plate, and a clamping plate is movably connected to the inner side of the movable block via a pin. The side of the clamping plate away from the movable block extends to the outer side of the cover plate and contacts the surface of the tank. The clamping plate can swing about the pin on the surface of the movable block as the axis.

[0011] As a preferred embodiment of this utility model, a sleeve plate is fixedly connected to the side of the clamping plate near the movable block, a lifting plate is provided at the top of the connecting frame, push rods located inside the sleeve plate are fixedly connected to both ends of the lifting plate, and cranks are movably connected to both sides of the screw sleeve through pins. The side of the crank away from the screw sleeve extends to the outside of the lifting plate and is movably connected to the lifting plate through a pin.

[0012] As a preferred embodiment of this utility model, a limiting plate is provided at the top of the lifting plate, both ends of which penetrate the lifting plate and are fixedly connected to the top of the cover plate, and the limiting plate is slidably connected to the lifting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses rigid claws to directly contact the surface of the tank for mechanical clamping, which completely avoids the problem of sliding displacement caused by insufficient friction and deformation of the airbag. The adjustment structure can simultaneously control the claw spacing and the squeezing intensity, so as to achieve precise adjustment of the sealing force.

[0014] 2. This utility model provides a labor-saving operating fulcrum through the rotary wheel design, and the sealing mechanism can be driven by rotating with one hand. The bidirectional screw converts the rotational motion into the linear movement of the screw sleeve, realizing the amplification and precise transmission of force.

[0015] 3. This utility model uses the sliding fit between the guide bar and the screw sleeve to forcibly restrict the rotation of the screw sleeve, ensuring that it moves only along the axial direction of the bidirectional screw, while eliminating the risk of screw sleeve wobble, ensuring the synchronous and symmetrical movement of the chuck, and avoiding stress concentration on one side.

[0016] 4. This utility model uses a clamping plate as a second sealing point to form a three-dimensional clamping system with the claws, which significantly improves the sealing reliability. Moreover, the clamping plate can adapt to the curvature of the tank surface by swinging through the pin shaft, ensuring uniform pressure distribution.

[0017] 5. This utility model automatically converts the horizontal movement of the screw sleeve into the downward pressure of the clamping plate through the crank mechanism, realizing single action and dual output. The crank mechanism amplifies the horizontal displacement into vertical displacement, obtaining a large clamping force with a small operating force.

[0018] 6. This utility model uses a limiting plate to forcibly constrain the lifting plate to only move vertically, avoiding the jamming of the clamping plate caused by the push rod being skewed. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, the present invention provides a dustproof ink box for color printing of packaging, including a can body 1; The top of the tank body 1 is provided with a cover plate 2. The top of the cover plate 2 is provided with a screw sleeve 3 through an adjustment structure. Both sides of the screw sleeve 3 are fixedly connected with claws 4. The side of the claws 4 away from the screw sleeve 3 extends to the outside of the cover plate 2 and is located outside the tank body 1. The side of the claws 4 away from the screw sleeve 3 contacts the surface of the tank body 1. The adjustment structure can adjust the spacing of the claws 4 and change the compression intensity.

[0023] refer to Figure 2 The adjustment structure includes a connecting frame 5 fixedly connected to the top of the cover plate 2. A bidirectional screw 6 is movably connected inside the connecting frame 5 via a bearing. A screw sleeve 3 is fitted onto the surface of the bidirectional screw 6 and threadedly connected to the bidirectional screw 6. Both ends of the bidirectional screw 6 extend to the outside of the connecting frame 5 and are fixedly connected to a rotating wheel 7.

[0024] As a technical optimization of this utility model, the design of the rotating wheel 7 provides a labor-saving operating fulcrum, and the sealing mechanism can be driven by rotating with one hand. The bidirectional screw 6 converts the rotational motion into the linear movement of the screw sleeve 3, realizing the amplification and precise transmission of force.

[0025] refer to Figure 3 A guide bar 8 is fixedly connected inside the connecting frame 5. The guide bar 8 extends into the inside of the screw sleeve 3 on the side away from the connecting frame 5 and is slidably connected to the screw sleeve 3.

[0026] As a technical optimization of this utility model, the guide bar 8 slides with the screw sleeve 3 to forcibly restrict the rotation of the screw sleeve 3, ensuring that it only moves along the axial direction of the bidirectional screw 6, while eliminating the risk of the screw sleeve 3 swaying, ensuring the synchronous and symmetrical movement of the chuck 4, and avoiding stress concentration on one side.

[0027] refer to Figure 4 Both sides of the top of the cover plate 2 are fixedly connected to movable blocks 9. The inner side of the movable block 9 is movably connected to a clamping plate 10 through a pin. The side of the clamping plate 10 away from the movable block 9 extends to the outer side of the cover plate 2 and contacts the surface of the tank 1. The clamping plate 10 can swing about the pin on the surface of the movable block 9 as the axis.

[0028] As a technical optimization of this utility model, the clamping plate 10 is used as the second sealing point to form a three-dimensional clamping system with the claw 4, which significantly improves the sealing reliability. Moreover, the clamping plate 10 can adapt to the surface curvature of the tank body 1 by swinging the pin shaft, ensuring uniform pressure distribution.

[0029] refer to Figure 2 A sleeve plate 11 is fixedly connected to the side of the clamping plate 10 near the movable block 9. A lifting plate 12 is provided on the top of the connecting frame 5. Push rods 13 located inside the sleeve plate 11 are fixedly connected to both ends of the lifting plate 12. Cranks 14 are movably connected to both sides of the screw sleeve 3 through pins. The side of the crank 14 away from the screw sleeve 3 extends to the outside of the lifting plate 12 and is movably connected to the lifting plate 12 through pins.

[0030] As a technical optimization of this utility model, the horizontal movement of the screw sleeve 3 is automatically converted into the downward pressure of the clamping plate 10 through the crank 14 mechanism, realizing single action and double output. The crank 14 mechanism amplifies the horizontal displacement into vertical displacement, so as to obtain a large clamping force with a small operating force.

[0031] refer to Figure 3 A limit plate 15 is provided on the top of the lifting plate 12. Both ends of the limit plate 15 pass through the lifting plate 12 and are fixedly connected to the top of the cover plate 2. The limit plate 15 is slidably connected to the lifting plate 12.

[0032] As a technical optimization of this utility model, the lifting plate 12 is forcibly constrained by the limiting plate 15 to only move vertically, so as to avoid the clamping plate 10 from being stuck due to the deviation of the push rod 13.

[0033] The working principle and usage process of this utility model are as follows: First, the cover plate 2 is placed on the top of the tank body 1. Then, the rotating wheel 7 drives the bidirectional screw 6 to rotate, forcing the screw sleeve 3 to move horizontally under the constraint of the guide bar 8. This causes the two side claws 4 to move towards each other and directly clamp the outer wall of the tank body 1. At the same time, the screw sleeve 3 pushes the lifting plate 12 to move vertically upward along the limiting plate 15 through the crank 14, causing the push rod 13 to lift the sleeve plate 11 at the bottom of the clamping plate 10. This forces the clamping plate 10 to swing inward and downward with the pivot of the movable block 9 as the fulcrum, forming a double sealing effect of radial clamping and oblique pressing with the claws 4. The reverse rotating wheel 7 simultaneously releases the claws 4 from clamping and pressing the clamping plate 10, realizing mechanical linkage sealing adjustment.

[0034] In summary, this ink dustproof box for color printing packaging uses rigid claws 4 to directly contact the surface of the can 1 for mechanical clamping, which completely avoids the problem of sliding displacement caused by insufficient friction and deformation of the airbag. The adjustable structure can simultaneously control the spacing of the claws 4 and the squeezing intensity, so as to achieve precise adjustment of the sealing force.
