Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, specifically a cleaning device for the production of thermos cups. Background Technology
[0002] Thermos cups are a common container in daily life. Their main function is to maintain the temperature of liquids (such as water, beverages, etc.) so that people can enjoy drinks at a suitable temperature at different times and places. Thermos cups need to be cleaned after production and before packaging to prevent foreign objects from adhering to the surface of the thermos cup, which would affect its appearance. Similarly, the inside of the thermos cup also needs to be cleaned.
[0003] Currently, there are two main methods for cleaning thermos cups: one is using ultrasonic cleaning equipment, and the other is using an electric brush. Although ultrasonic cleaning equipment has a good cleaning effect, the equipment cost and maintenance cost are relatively high. While using an electric brush is relatively cheaper, it has encountered many problems in actual operation. Since the radius of the mouth of a common thermos cup is usually slightly smaller than the radius of the inner liner, the size requirements for the brush are quite strict. If the brush is too large, the bristles will rub against the mouth of the cup when entering the inside of the thermos cup, causing the bristles to bend. Over time, the bristles will curl up or even break, resulting in a decrease in cleaning effect. If the brush is too small, although it can enter the inside of the thermos cup, it is difficult to reach the entire inner surface of the inner liner, resulting in a weakened cleaning effect that cannot meet production requirements.
[0004] In view of the above, this application is hereby submitted. Utility Model Content
[0005] The purpose of this invention is to provide a cleaning device for the production of thermos cups, so as to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides a cleaning device for the production of thermos cups, including a fixed base and bearing brackets fixed to the top of the fixed base at both ends along its length. The same rotating shaft is rotatably installed on the side of the two bearing brackets that are close to each other. A plurality of sliding grooves are provided on the outer arc wall of one end of the rotating shaft in a circular array about the axis of the rotating shaft. An adjustment mechanism is provided at the end of the rotating shaft near the sliding groove. The adjustment mechanism includes two sliders that slide in the sliding groove. A rotating rod is rotatably connected to the side wall of each of the two sliders away from the rotating shaft. A fixed plate is rotatably connected to the end of the rotating rod away from the slider. A limit rod is fixedly connected to the inner arc wall of the fixed plate near the other end of the rotating shaft. A slot is provided on the outer arc wall of the rotating shaft at the position corresponding to the limit rod. The limit rod slides in the slot.
[0007] A slide groove 1 is provided at the end of the slide groove 1 that is away from the fixed plate along the axis of rotation. A slide groove 2 is provided on the side of slide groove 2 that is away from slide groove 1. A fixed rod is fixed on the side wall of the slider that is close to slide groove 2. The fixed rod slides in slide groove 2. A sliding ring is fixed at the end of the fixed rod that is away from the slider. The sliding ring slides in slide groove 3. A channel 1 is opened on the outer arc wall of the rotating shaft at the position corresponding to slide groove 3. A fixed ring is fixed on the outer arc wall of the sliding ring. The fixed ring slides in channel 1.
[0008] The length direction of the limiting rod is parallel to the radial direction of the rotating shaft, and the rotation plane of the rotating rod and the slider is parallel to the axial direction of the rotating shaft. Brush bristles are fixed on the outer arc wall of the fixed plate, and a sealing plate is fixed on the side wall of the fixed plate away from the gear. When two adjacent fixed plates abut against each other, the two adjacent sealing plates abut against each other and seal the nozzle.
[0009] Furthermore, the slide groove 1 set on the outer arc wall of the rotating shaft avoids the slot. The length directions of slide groove 1, slide groove 2 and slide groove 3 are all parallel to the axis of the rotating shaft. Slide groove 2 connects slide groove 1 and slide groove 3. A return spring is fixed on the side wall of the slip ring away from the fixed rod. The end of the return spring away from the slip ring is fixed on the inner side wall of slide groove 3 away from slide groove 2.
[0010] Furthermore, a gear 1 is coaxially fixed to the side wall of the rotating shaft away from the adjustment mechanism. A gear 2 is meshed with one side of the gear 1. A motor is fixed to the side of the gear 2 that is axially away from the rotating shaft. The motor is fixed to the top of the fixed base. A channel 2 that runs through the shaft along the axis is opened on the side wall of the rotating shaft and the gear 1 that are close to each other. The channel 2 does not communicate with the slide groove 1, slide groove 2, slide groove 3 and slot. A nozzle is fixed to the end of the channel 2 that is close to the fixed plate.
[0011] Furthermore, a limiting clamp is fitted on the outer side of the fixed ring. The horizontal cross-section of the limiting clamp along the axis of rotation is "door" shaped, and the opening of the limiting clamp faces the fixed ring. A ball is embedded on the side wall of the limiting clamp that is close to the fixed ring. The ball rolls and abuts against the side wall of the fixed ring. Several limiting blocks are fixed on the inner arc wall of the fixed ring in a circular array about the axis of rotation. The limiting blocks slide in the first channel. A cylinder is fixed on the side of the limiting clamp that is close to the first gear. The cylinder is located on the side of the first gear away from the second gear and is fixed to the top of the fixed seat.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. By adjusting the mechanism, this cleaning device can adapt to the inner liner of thermos cups of different sizes. At the same time, when entering the bottle, the position of the fixing plate can be adjusted to avoid the brush bristles from rubbing or squeezing against the rim of the cup, thus improving the life of the brush bristles. In addition, whether the inner liner radius is small or large, the position of the fixing plate can be adjusted to ensure that the brush can completely cover the inner liner surface, achieving a good cleaning effect.
[0014] 2. The cleaning agent can be sprayed out through the connecting pipe of channel two to assist in cleaning and further enhance the cleaning effect. In addition, the operation of this cleaning equipment is relatively simple. The fixed plate can be adjusted by simply driving the fixed ring to slide in channel one through the cylinder. There is no need to change brushes of different sizes, which reduces the difficulty of operation and cost. Attached Figure Description

[0023] 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.
[0024] Please see the appendix Figure 1 To be continued Figure 4 This utility model provides a cleaning device for the production of thermos cups: it includes a fixed base 10 and bearing brackets 11 fixed to the top of the fixed base 10 at both ends along its length. The two bearing brackets 11 are rotatably mounted on the side close to each other. A plurality of sliding grooves are provided on the outer arc wall of one end of the rotating shaft 12 in a circular array about the axis of the rotating shaft 12. An adjustment mechanism is provided at the end of the rotating shaft 12 near the sliding grooves. The adjustment mechanism includes two sliders 23 that slide in the sliding grooves. A rotating rod 21 is rotatably connected to the side wall of each slider 23 away from the rotating shaft 12. A fixed plate 20 is rotatably connected to the end of the rotating rod 21 away from the slider 23. A limiting rod 22 is fixedly connected to the inner arc wall of the fixed plate 20 near the other end of the rotating shaft 12. A slot is provided on the outer arc wall of the rotating shaft 12 at the position corresponding to the limiting rod 22. The limiting rod 22 slides in the slot.
[0025] A second slide groove is provided at the end of the first slide groove along the axis of the rotating shaft 12 away from the fixed plate 20. A third slide groove is provided on the side of the second slide groove away from the first slide groove. A fixed rod 24 is fixed on the side wall of the slider 23 near the second slide groove. The fixed rod 24 slides in the second slide groove. A sliding ring 25 is fixed at the end of the fixed rod 24 away from the slider 23. The sliding ring 25 slides in the third slide groove. A channel is provided on the outer arc wall of the rotating shaft 12 at the position corresponding to the third slide groove. A fixed ring 32 is fixed on the outer arc wall of the sliding ring 25. The fixed ring 32 slides in the channel.
[0026] The first slide groove is set on the outer arc wall of the rotating shaft 12, avoiding the slot. The length directions of the first slide groove, the second slide groove and the third slide groove are all parallel to the axial direction of the rotating shaft 12. The second slide groove connects the first slide groove and the third slide groove. A return spring 26 is fixed on the side wall of the slip ring 25 away from the fixed rod 24. The end of the return spring 26 away from the slip ring 25 is fixed on the inner side wall of the third slide groove away from the second slide groove.
[0027] It should be noted that: the cylinder 30 drives the fixed ring 32 by pushing the limit clamp 31, the fixed ring 32 drives the slip ring 25 to slide in the slide groove three, and at the same time the return spring 26 is stretched. The slip ring 25 drives the slider 23 to slide in the slide groove one through the fixed rod 24. The sliding of the slider 23 forces the rotating rod 21 to rotate, thereby causing the fixed plate 20 to move away from the rotating shaft 12. The return spring 26 is used to assist the slip ring 25 to return to its original position.
[0028] Please see the appendix Figure 1 To be continued Figure 4The present invention provides a technical solution: a gear 13 is coaxially fixed on the side wall of the rotating shaft 12 away from the adjustment mechanism, a gear 2 14 is meshed on one side of the gear 13, a motor 15 is fixed on the side of the gear 2 14 away from the rotating shaft 12, the motor 15 is fixed on the top of the fixed base 10, and a channel 2 is provided on the side wall of the rotating shaft 12 and the gear 13 that are close to each other along the axis. The channel 2 does not communicate with the slide groove 1, slide groove 2, slide groove 3 and slot. A nozzle is fixed on the end of the channel 2 near the fixed plate 20.
[0029] It should be noted that: the motor 15 drives the gear 14, which in turn meshes with the gear 13 to drive the rotating shaft 12 and the components on it to rotate, thus reserving space for pipe connection through the off-axis drive.
[0030] Please see the appendix Figure 1 To be continued Figure 4 This utility model provides a technical solution: a limiting clip 31 is sleeved on the outer side of the fixed ring 32. The horizontal cross section of the limiting clip 31 along the axis of the rotating shaft 12 is "door" shaped, and the opening of the limiting clip 31 is set towards the fixed ring 32. A ball is embedded on the side wall of the limiting clip 31 that is close to the fixed ring 32. The ball rolls and abuts against the side wall of the fixed ring 32. Several limiting blocks are fixed on the inner arc wall of the fixed ring 32 in a circular array about the axis of the rotating shaft 12. The limiting blocks slide in the channel one. A cylinder 30 is fixed on the side of the limiting clip 31 that is close to the gear one 13. The cylinder 30 is set on the side of the gear one 13 away from the gear two 14. The cylinder 30 is fixed to the top of the fixed seat 10.
[0031] It should be noted that when the cylinder 30 extends, it will push the limiting clamp 31, which in turn will drive the fixed ring 32 to move axially along the rotating shaft 12. Due to the action of the limiting block, the fixed ring 32 will rotate synchronously with the rotating shaft 12. The ball bearings are used to reduce the friction between the fixed ring 32 and the limiting clamp 31.
[0032] Please see the appendix Figure 1 To be continued Figure 4 The present invention provides a technical solution: the length direction of the limiting rod 22 is parallel to the radial direction of the rotating shaft 12, the rotation plane of the rotating rod 21 and the slider 23 is parallel to the axial direction of the rotating shaft 12, the outer arc wall of the fixing plate 20 is fixed with bristles, and the side wall of the fixing plate 20 away from the gear 13 is fixed with a sealing plate. When two adjacent fixing plates 20 abut against each other, the two adjacent sealing plates abut against each other and seal the nozzle.
[0033] It should be noted that the limiting rod 22 is used to restrict the movement direction of the fixed plate 20 and prevent the fixed plate 20 from rotating.
[0034] Working principle:
[0035] This device can be fixed on an electric slide rail, which is fixed on a workbench. The thermos cup to be cleaned is transported to the side of the adjustment mechanism by a robotic arm or a transport device. At this time, the electric guide rail drives this device to move closer to the thermos cup so that the fixing plate 20 can enter the inside of the thermos cup.
[0036] In the initial state, several fixed plates 20 abut against each other to form a hollow cylinder, thereby reducing the cross-sectional radius so that the fixed plates 20 can smoothly enter the interior of the thermos. When they are fully inside or in the right position (the depth is determined by the thermos's own parameters), the motor 15 starts to control the rotating shaft 12 to rotate, and then cleans the inner wall of the thermos. The adjustment mechanism can also make multiple fixed plates 20 move synchronously in opposite directions to the rotating shaft 12 to increase the cross-sectional radius so that the bristles can fully contact the inner wall of the thermos and ensure the cleaning effect.
