Technical Field

[0001] The invention belongs to the technical field of thermos cup processing and relates to a cleaning device for a thermos cup. Background Art

[0002] During the production process of the thermos cup, both the outer liner and the inner liner need to be cleaned, sprayed and dried to remove the metal residues remaining on their surface.

[0003] At present, the cleaning line for thermos cups is not perfect. Usually, the outer wall of the thermos cup is simply sprayed with clean water to clean it, so the burrs and waste attached to the thermos cup during the production process cannot be effectively removed.

[0004] Therefore, it is necessary to develop a device specifically for cleaning thermos cups. Summary of the invention

[0005] The purpose of the present invention is to propose a cleaning device for a thermos cup in order to solve the problem that the cleaning process in the existing thermos cup production process is not practical, resulting in poor cleaning effect.

DETAILED DESCRIPTION

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] The cleaning device of the thermos cup comprises a front dissolving and washing assembly for immersing the thermos cup for cleaning, a rear spraying and washing assembly for spraying clean water on the thermos cup, and a conveying assembly for conveying the thermos cup.

[0018] like Figure 1 As shown, the front-end dissolving and washing assembly includes a washing box 1, and the washing box 1 has two independently separated washing chambers 2. The front washing chamber 2 is for acid washing, and the rear washing chamber 2 is for clean water washing. The conveying assembly sends the thermos cup original into the front washing chamber 2 for acid washing, and then sends it into the rear washing chamber 2 for clean water washing, and then sends it to the rear spraying assembly for clean water spraying.

[0019] After the acid wash is completed, there will be acid water remaining on the surface of the thermos cup. In order to clean the acid water on the surface of the thermos cup, it is necessary to perform a water wash, immerse the thermos cup in water for cleaning. However, after a long time of water washing, a large amount of acid water left by the thermos cup will remain in the water. Therefore, all thermos cups cannot be completely cleaned after being immersed in clean water. Therefore, rear-end spray washing is required afterwards. Spraying is to spray the thermos cup directly with clean water. The thermos cup will be absolutely cleaned under clean water. After cleaning, subsequent drying operations will be carried out.

[0020] The pickling method uses citric acid.

[0021] Because citric acid has a strong chelating ability for metal ions such as trivalent iron ions and divalent steel ions, it has a low corrosion rate on metals. Copper, brass, aluminum, chromium, nickel and other metals are resistant to the erosion of citric acid. It can not only effectively remove impurities and oxides on the metal surface, but also causes less corrosion to the metal itself. It is a relatively mild cleaning agent.

[0022] The conveying components include multiple groups of conveying shafts 3 rotatably arranged in the cleaning box 1, sprockets 4 are fixedly sleeved on both sides of the conveying shafts 3, chains 5 are sleeved on the sprockets 4, multiple placement plates 6 are fixedly arranged between the two groups of chains 5, the placement plates 6 are evenly spaced longitudinally, and multiple placement tables for placing thermos cups are spaced laterally on each placement plate 6, among which several conveying shafts 3 are located in the two cleaning chambers 2 to ensure that the placement tables can be immersed in the two cleaning chambers 2, and one or more conveying shafts 3 are connected to a conveying driver (not shown in the figure). During the operation of the chain 5, its placement plate 6 will pass through the front cleaning chamber 2, the rear cleaning chamber 2, and the rear end spray assembly in sequence.

[0023] The conveying drive uses one or more unidirectional motors and a transmission that can continuously output rotational power. When multiple unidirectional motors are used, the output frequency and speed of all unidirectional motors should be consistent.

[0024] In the process of placing the thermos cups on the initial position placement table, a robot is generally used to complete this task, placing multiple thermos cups on all the placement tables on the same placement plate 6 at one time, and then after the placement plate 6 moves with the chain 5, the next placement plate 6 returns to the initial position, and the placement is repeated in a cycle.

[0025] A single placement plate 6 is provided with four groups of placement platforms.

[0026] The rear end spray washing assembly includes an external spray group (not shown in the figure), on which a plurality of external sprayers are arranged, and the nozzles of the external sprayers are downward to spray clean water on the passing thermos cup.

[0027] The structure of the external spray group is relatively simple. After the external spray group is fixed, the external sprayer continuously sprays clean water downwards, and the thermos cup passing by will be sprayed with clean water, completing the spray washing operation.

[0028] However, because the thermos cup has undergone an immersion washing process, simply spraying the thermos cup from the outside only cleans the outside of the thermos cup, and the inner liner or the inside of the outer liner of the thermos cup cannot be sprayed with clean water. Therefore, an internal spray group is also provided below to spray the inside of the thermos cup. At the same time, because the thermos cup continues to move forward driven by the chain 5, in order to allow the internal spray group to penetrate into the interior of the thermos cup for spraying, the internal spray group also needs to move forward a certain distance with the thermos cup to ensure that there is sufficient time to spray the inside of the thermos cup. This is because each link of the equipment requires the conveying assembly to carry the thermos cup forward continuously. Therefore, if the conveying assembly stops for internal spraying in this specific link of internal spraying, it will affect other links. In order to avoid this situation, the best form is to ensure that the conveying assembly continues to move the thermos cup forward, but the internal spray group can move forward with the thermos cup for a while and then return to its position immediately.

[0029] The rear end spray washing assembly also includes an inner spray group, which includes an inner spray plate 7, an inner sprayer 8 fixedly arranged on the inner spray plate 7 and having the same number and interval as the placement table on the single placement plate 6, two groups of symmetrically arranged jigs 9 and slides 10, two groups of driving blocks 11 respectively slidably arranged on the slides 10, and a linear driving component (not shown in the figure) for driving the driving block 11 to slide back and forth on the slide 10. The linear driving component, jigs 9 and slides 10 are fixed parts. A square opening 12 is opened on the jigs 9, and both sides of the inner spray plate 7 are fixed. A magnetic block is provided, which is located in a square opening 12. A magnet is provided inside the edge of the square opening 12 of the mold frame 9, and the magnet adsorbs the block to the edge of the square opening 12. The block and the edge of the square opening 12 are both made of smooth materials. When an external force is applied, the block can slide on the edge of the square opening 12, but it is always attached and cannot be separated due to the magnetic adsorption effect. An oblique straight slot hole 13 is provided on the slide 10, and a cylindrical transmission rod 14 is provided at the outer end of the block. The end of the transmission rod 14 is inserted into the oblique straight slot hole 13 and the two are tangent.

[0030] The linear drive components can be realized by telescopic cylinders or telescopic oil cylinders. Figures 2 to 4 As shown, under the action of the square opening 12 and the block body and the magnetic adsorption force between the two, the block body can only slide on the square opening 12. Then, after the driving block 11 moves forward or backward, the oblique straight slot hole 13 of the slide 10 will first act on the transmission rod 14, so that the transmission rod 14 moves with the entire inner spray plate 7 in the height direction. When it moves to the limit in the height direction, it proves that the transmission rod 14 is already at the end of the oblique straight slot hole 13. At this time, continuing to move the driving block 11 in the same direction will pull the transmission rod 14, allowing the transmission rod 14 to move with the inner spray plate 7. Of course, the entire movement process is carried out under the edge restriction path of the square opening 12.

[0031] Therefore, after the linear drive component performs a single back and forth movement, the inner spray plate 7 can descend, move forward, rise, and move backward along the square path at the edge of the square opening 12 to return to the initial point in sequence. The purpose of the descent is to allow the inner sprayer 8 to penetrate into the cavity of the bottom thermos cup. The forward movement is because the thermos cup is moving, so the inner sprayer 8 must move forward with the thermos cup for a certain distance to ensure time to complete the internal spraying. The ascent is to separate the inner sprayer 8 from the cavity of the thermos cup after the internal spraying is completed, and the backward movement is to return the inner sprayer 8 to the initial position for the next internal spraying process.

[0032] The above design can be adopted because the inner spray plate 7 and the multiple inner sprayers 8 thereon are light parts themselves, so the magnetic adsorption force is sufficient to support the entire inner spray plate 7, and the oblique straight slot hole 13 drives the transmission rod 14 because the entire inner spray plate 7 is light enough so that there will be no gravity interference.

[0033] A diffusion plate 15 is provided at the nozzle of the inner spray plate 7, and the diffusion plate 15 sprays the clean water sprayed from the nozzle of the inner spray plate 7 to all around.

[0034] When the nozzle penetrates into the inner cavity of the thermos cup, it needs to spray clean water all around to ensure that the inner cavity is completely sprayed.

[0035] The square opening 12 and the block body are both square, and the oblique straight slot hole 13 is at an angle of 45 degrees to the ground.

[0036] The square opening and the block body are both square, and the oblique straight slot hole is at a 45-degree angle to the ground.
