Description

Technical Field

[0001] The present invention relates to the technical field of food factory transportation, in particular to a transportation device used in a food factory. Background Art

[0002] In the food and beverage industry, ensuring product quality and production efficiency is crucial, especially during the production and packaging of beverage bottles. After filling, beverage bottles undergo multiple stages, including conveying, testing, and sorting, before they are finally packaged and shipped. However, existing conveying and testing equipment suffers from numerous deficiencies in practical applications, severely impacting production efficiency and product quality.

[0003] For example, Publication No. CN104773485B discloses a beverage bottle conveyor, in which the conveyor belt is stepped, and bottles fed in a single row are automatically cut into a row and then forcibly pushed into a bottle warmer. There is no squeezing force between the bottles, which ensures a stable feeding speed and prevents bottle jams. Beverage bottles can be lined up in rows and enter the bottle warmer, and each row of bottles stays in the bottle warmer for the same amount of time. However, existing airtightness testing equipment typically requires a separate testing station, resulting in a complex and inefficient testing process. Furthermore, traditional testing equipment is susceptible to external interference during the testing process, resulting in unstable detection accuracy. Furthermore, during the transportation of beverage bottles, the outer wrapping paper is prone to wrinkles or bubbles due to friction or collisions, affecting packaging quality. Traditional conveying equipment lacks a smoothing function for the wrapping paper, making it unable to effectively address these issues. Therefore, a conveying device for use in food processing plants was proposed to address these issues. Summary of the Invention

[0029] Working principle: When canning beverages, it is necessary to inspect the canned beverages to avoid packaging beverages that are not sealed in time; The bottle is then moved onto the conveyor belt 22 and the bottle is then brought into contact with the movable plate 85. The movable plate 85 is pressed against the bottle by the action of the return spring 83, and the movable plate 85 is pressed against the outer wall of the bottle, thereby smoothing the outer wall of the bottle. Furthermore, when the beverage bottle enters the conveyor belt, the electric telescopic rod 1 33 and the electric telescopic rod 2 34 on both sides are synchronously started to move, which will drive the movable block 32 to move forward and backward and the lifting platform 35 to move up and down, thereby changing the forward and backward movement of the roller 392 and squeezing the beverage bottle, thereby detecting the air tightness of the beverage bottle. At the same time, the roller 392 can also move up and down, so that the beverage bottle can be squeezed from top to bottom, thereby squeezing the advertising paper attached to the outer wall of the beverage bottle, so that the advertising paper is better attached. At the same time, the servo motor 37 is started, and the gear box 393 is driven by the transmission box 38, so that the roller 392 on one side can be driven to rotate, and the roller 392 on the other side is driven to rotate by the two chain boxes 1 39 and chain box 2 391, so that the advertising paper on the outer wall of the beverage bottle can be rolled and squeezed, further promoting the smoothing and attachment of the advertising paper. Furthermore, after the beverage bottles are conveyed to one side of the conveyor belt, they are blocked by the baffle 72. When the required number of beverage bottles is reached, the drive motor 59 is started, thereby driving the drive shaft 55 to rotate, thereby driving the pulley set 56 to move, and at this time driving the slider 58 to move on the slide post 57, thereby driving the lifting plate 54 to move upward, and synchronously driving the support plate 591 and the arrangement table 592 to move upward, so as to correspond to the conveyor belt 22. At the same time, the other side of the belt of the pulley set 56 drives the limit rod 73 to move downward, and at the same time drives the baffle 72 to move downward, thereby moving downward in the fixed sleeve 71, thereby breaking away from the obstruction of the beverage bottles, so that the beverage bottles are conveyed by the conveyor belt 22 and enter the arrangement table 592 for arrangement; At the same time, by opening the cylinder 67, the cylinder 67 will push the push block 65 to move on the round rod 66, thereby pushing the sliding table 64 to move, and making the slide 63 slide on the slide rod 62, and push the push rod 68 and the push plate 69 to push the beverage bottle to move and fit it to the flow channel baffle, so that the beverage bottles can be arranged neatly, thereby making it easier for the robot to grab and transfer the neatly arranged beverage bottles, thereby improving work efficiency.
