Description

Technical Field

[0001] The utility model relates to the technical field of rubber sheet production, in particular to a coding packaging device for rubber sheet production. Background Art

[0002] As an important industrial material, rubber sheet is widely used in a variety of fields, including automotive parts, industrial seals, and building waterproofing materials, due to its superior physical and chemical properties. During the production process, rubber undergoes a series of steps, including mixing, vulcanization, calendaring, or molding, to produce uniform, stable rubber sheets.

[0003] As industry demands for product quality and traceability increase, rubber sheets require post-production labeling. This is typically achieved through inkjet printing, which incorporates key information such as production date, serial number, intended use, and batch number. These markings not only facilitate production process management and optimization but also facilitate downstream applications, including quality inspection, inventory management, and market distribution.

[0004] Traditionally, the coding of rubber sheets and the subsequent packaging (including sorting, stacking, and boxing) are performed by separate equipment or stations. The coding equipment uses a high-precision printhead to print the code on the rubber sheet surface, ensuring the clarity and durability of the information. The packaging equipment, on the other hand, separates the rubber sheets, sorts them, stacks them, and packs them into boxes according to specific quantities.

[0005] However, because coding and packaging operations are independent of each other in time and space, this separate operation mode brings multiple problems. First, the operational process is fragmented, often requiring more manual intervention and handling, which increases labor costs and the probability of error. Second, because the rubber sheets after coding need to wait before entering the packaging process, the efficiency of the entire production line is reduced and a large amount of factory space is occupied. In view of this, we propose a coding and packaging device for rubber sheet production. Utility Model Content

[0006] The purpose of the utility model is to provide a coding packaging device for rubber sheet production to solve the problems raised in the above background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A coding packaging device for rubber sheet production includes a U-shaped frame, wherein support frames are provided at the bottom of the U-shaped frame and near the left and right sides, a fixed bottom plate is provided at the bottom of the right side of the support frame on the right, a support plate is placed on the top of the fixed bottom plate, and a packaging box is placed on the top of the support plate. The support plate matches the packaging box. When the model of the packaging box is changed, the support plate must also be replaced with a corresponding model. This is mainly to fix the position of the packaging box and ensure that the two vacuum suction cups can absorb the rubber sheet and move to the top of the packaging box so that the rubber sheet can be smoothly placed in the packaging box;

[0009] A conveyor belt is provided in the U-shaped frame, and a stepper motor for driving the conveyor belt is provided on the rear side of the U-shaped frame.

[0011] The first electric cylinder drives the first movable plate to move left and right, and the second electric cylinder drives the second movable plate to move up and down. When the rubber sheet is coded and moves to directly below the first movable plate, the second electric cylinder drives the second movable plate to move downward until the two vacuum suction cups touch the top of the rubber sheet and adsorb the rubber sheet. Then the second electric cylinder drives the second movable plate to reset upward. At the same time, the first electric cylinder drives the first movable plate to move to the right until the rubber sheet moves to directly above the packaging box. At this time, the second electric cylinder drives the second movable plate to move downward, so that the rubber sheet moves down into the packaging box, and then the vacuum suction cup stops the adsorption operation, so that the rubber sheet can enter the packaging box. Afterwards, the first electric cylinder and the second electric cylinder cooperate to reset the two vacuum suction cups. Repeat the above operation. Multiple rubber sheets can be stacked in the packaging box to achieve coding and packaging of the rubber sheets.

[0012] Preferably, positioning holes are provided at the top of the fixed base plate and near the front and rear ends on the left side, and positioning blocks are provided at the bottom of the support plate and near the front and rear ends on the left side. The two positioning blocks are respectively inserted into the two positioning holes, which is convenient for positioning the support plate and also convenient for staff to replace different support plates.

[0017] Preferably, the middle parts of the opposite sides of the two fixed seats are threadedly connected with threaded rods, and the opposite ends of the two threaded rods are rotatably connected to moving blocks, and the bottoms of the two moving blocks are provided with strip cross plates, and the bottoms of the two strip cross plates are rotatably connected to a plurality of guide wheels arranged equidistantly on the left and right. The bottoms of the guide wheels do not contact the surface of the conveyor belt, and the moving blocks are driven back and forth by the threaded rods, thereby adjusting the distance between the two strip cross plates, so that the two guide wheels arranged relatively front and back are respectively located on the front and back sides of the rubber sheet, which play a role of centering the rubber sheet, so that the rubber sheet can move stably to the right with the conveyor belt, and at the same time, it is beneficial for the conveying mechanism to smoothly move the rubber sheet into the packaging box.

[0018] Preferably, two third positioning rods are provided on the opposite sides of the two moving blocks and are symmetrically arranged on the left and right. The end of the third positioning rod away from the moving block passes through the side of the fixed seat to improve the stability of the moving block.

[0021] 2. The inkjet packaging device for rubber sheet production, the support plate and the packaging box are designed as interchangeable components, which can quickly adapt to packaging needs of different sizes and specifications. Only the corresponding accessories need to be replaced to adapt to different production requirements, thereby improving the flexibility and efficiency of the equipment.

[0022] 3.

After the rubber sheet is coded and moves to the bottom of the first movable plate 63, the second electric cylinder 64 drives the second movable plate 65 to move downward until the two vacuum suction cups 66 are against the top of the rubber sheet and adsorb the rubber sheet. Then the second electric cylinder 64 drives the second movable plate 65 to reset and move upward. At the same time, the first electric cylinder 62 drives the first movable plate 63 to move to the right until the rubber sheet moves to the top of the packaging box 11.

[0039] Furthermore, two second positioning rods 650 are provided on the top of the second movable plate 65 and are symmetrically arranged front to back. The top ends of the second positioning rods 650 pass through the bottom of the first movable plate 63 to improve the stability of the second movable plate 65 when it moves up and down.

[0040] Furthermore, the U-shaped frame 1 is also provided with a centering component 9 for centering the position of the rubber sheet.

When the rubber sheet to be coded is at the conveying position, the second electric cylinder 64 drives the second movable plate 65 downward, so that the vacuum suction cup 66 contacts and adsorbs the surface of the rubber sheet. Then, the second electric cylinder 64 drives the second movable plate 65 upward and resets, lifting the rubber sheet away from the conveyor belt 2. The first electric cylinder 62 drives the first movable plate 63 to move rightward, moving the rubber sheet to just above the packaging box 11. Then, the second electric cylinder 64 drives the second movable plate 65 downward, placing the rubber sheet in the packaging box 11 and releasing the vacuum adsorption, so that the rubber sheet remains in the packaging box 11. This operation is repeated to stack the coded rubber sheets in the packaging box 11 in sequence. Through the above steps, this device improves the degree of production automation, optimizes coding and packaging efficiency, and effectively reduces labor costs and error rates.
