Abstract

This invention relates to the field of cleaning equipment technology, and discloses a bottle cleaning device and a process for cleaning and labeling fire extinguisher bottles. The bottle positioning mechanism of this invention can drive a bottle to move and restrict it to a cleaning position located on one side of the cleaning mechanism as it passes by. After the bottle in the cleaning position is cleaned by the cleaning mechanism, the bottle positioning mechanism resets and releases the cleaned bottle. The cleaned bottle continues to move with the material conveyor belt and detaches from the cleaning position. Simultaneously, the next bottle to be cleaned is released by the bottle interception mechanism and moved and held in the cleaning position by the material conveyor belt and the bottle positioning mechanism.

Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, specifically to a bottle cleaning device and a fire extinguisher bottle cleaning and labeling process. Background Technology

[0002] Bottle cleaning equipment is an indispensable key piece of equipment in the food, pharmaceutical, and chemical industries. It is primarily used for the efficient and thorough cleaning of various bottle-shaped containers to ensure that no residual contaminants remain on the exterior or interior of the containers, meeting hygiene and safety standards and the requirements of subsequent processing such as labeling. It also provides comprehensive pollution control for harmful substances generated during processing. With the development of automation technology, mechanical bottle cleaning equipment has gradually replaced manual labor, becoming the mainstream solution. Existing bottle cleaning equipment typically employs technologies such as high-pressure spraying, ultrasonic cleaning, and mechanical brushing to improve cleaning efficiency and consistency.

[0003] In existing technologies, with the expansion of production scale and the increasing requirements for cleaning quality, the limitations of traditional cleaning equipment have gradually become apparent. Most existing bottle cleaning equipment is designed based on the concept of batch processing, that is, cleaning multiple bottles simultaneously to improve overall efficiency. While this design can shorten the cleaning time per batch, it also introduces significant interference problems. The equipment is prone to reduced cleaning effectiveness due to bottles being too close together or uneven distribution of cleaning media.

[0004] Especially during continuous bottle cleaning, when multiple brush heads work simultaneously, the deformation and wear of the bristles are exacerbated by the small gaps between the bottles, resulting in uneven scrubbing force. In rotary scrubbing equipment, the contact pressure between the brush head and the bottle fluctuates due to the interaction between adjacent brush heads, causing some bottle surfaces to experience excessive friction while other areas are insufficiently cleaned. This interference not only reduces the cleaning effect but may also accelerate brush head wear and increase maintenance costs. More seriously, contaminants detached from the bottle may be agitated by the water flow and re-adhere to other bottles, causing secondary pollution and significantly reducing the cleaning effectiveness. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a bottle cleaning device and a fire extinguisher bottle cleaning and labeling process.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A bottle cleaning device includes a cleaning mounting base mounted on the bottom end of a material conveyor belt. The cleaning mounting base extends from both ends of the material conveyor belt and is respectively provided with a bottle positioning mechanism and a bottle cleaning mechanism. A bottle interception mechanism is provided on the side of the material conveyor belt and at the front end of the bottle cleaning mechanism. The bottle interception mechanism can intercept several bottles conveyed from the material conveyor belt on a side away from the bottle cleaning mechanism. The bottle positioning mechanism can drive a bottle to move and maintain it in a cleaning position located on the side of the bottle cleaning mechanism. The bottle is cleaned by the bottle cleaning mechanism in the cleaning position. After cleaning one bottle, the bottle positioning mechanism resets, and the cleaned bottle continues to move with the material conveyor belt, detaching from the cleaning position. The next bottle to be cleaned is released by the bottle interception mechanism and moved and maintained in the cleaning position by the combined drive of the material conveyor belt and the bottle positioning mechanism.

[0008] Preferably, the sides of the material conveyor belt are respectively equipped with limiting guide plates, and each bottle conveyed by the material conveyor belt can be conveyed under the restriction of each of the limiting guide plates; the portion of the limiting guide plate above the cleaning mounting base is provided with an operating notch, and the bottle positioning mechanism and the bottle cleaning mechanism can respectively extend into the operating notch to perform operations; the operating notch of the limiting guide plate located in the bottle cleaning mechanism is provided with an inclined guide plate, and the inclined guide plate is inclined from the bottle interception mechanism toward the bottle cleaning mechanism.

[0009] Preferably, the material conveyor belt includes a conveyor support frame, inside which are arranged a plurality of support sprockets, and at one end of the conveyor support frame is a drive sprocket. A conveyor chain is arranged on the outside of each of the support sprockets and the drive sprocket. The conveyor chain includes a plurality of conveyor links, and each conveyor link includes a link plate. An outer shaft and an embedded shaft are respectively arranged on both sides of the link plate. The embedded shaft of one conveyor link and the outer shaft of another conveyor link can together form a link shaft. Two adjacent conveyor links can be rotatably connected through the combined link shaft.

[0010] Preferably, a drive motor is provided on one side of the drive sprocket, a drive gear is fixedly provided on the output shaft of the drive motor, and a driven gear is coaxially fixed on one end of the drive sprocket; the drive gear and the driven gear are connected and driven by a transmission belt; the support sprocket can fit against the bottom surface of the link plate of the conveyor chain link that passes through, and support the conveyor chain link that passes through; the drive sprocket can mesh with the link shaft of the combined conveyor chain link that passes through, and drive the conveyor chain link that passes through to move.

[0011] Preferably, the bottle cleaning mechanism includes a cleaning support, a cleaning mounting roller rotatably mounted on the top of the cleaning support, a cleaning drive motor disposed inside the cleaning support, the cleaning drive motor being poweredly connected to the cleaning mounting roller, a cleaning sleeve sleeved on the outside of the cleaning mounting roller, the cleaning sleeve being separable from the cleaning mounting roller; the bottle interception mechanism includes an interception lifting bracket, an interception cylinder disposed on the top of the interception lifting bracket, and an interception cone disposed on the movable end of the interception cylinder, the interception cone being made of an elastic material.

[0012] Preferably, the bottle positioning mechanism includes a positioning support, a driving support slidably disposed at the top of the positioning support, and a positioning driving cylinder disposed at the top of the positioning support and on the side of the driving support away from the bottle cleaning mechanism; a positioning wedge, a positioning driving turntable and a positioning driving motor are disposed at the top of the driving support, the positioning driving motor is rotatably connected to the positioning driving turntable, and a positioning inclined surface is disposed on the side of the positioning wedge near the bottle cleaning mechanism and near the positioning driving turntable.

[0013] Preferably, the distance between the two supporting sprockets located on both sides of the bottle positioning mechanism is greater than the width of the bottle positioning mechanism; a separating guide mechanism is provided at the bottom end of the drive support near the bottle cleaning mechanism, the separating guide mechanism including a chain link pressing wedge plate, a supporting guide wedge plate and a rotating support unit; during the extension and retraction of the movable end of the positioning drive cylinder, the separating guide mechanism can move closer to and further away from the side of the bottle cleaning mechanism synchronously with the drive support.

[0014] Preferably, as the chain link pressing wedge moves closer to the bottle cleaning mechanism, the chain link pressing wedge can gradually press down several conveyor chain links that are in contact with the chain link pressing wedge, creating a gap between the bottom of the bottle and the conveyor chain links; the support guide wedge lags behind the chain link pressing wedge by one end. After a gap is created between the bottom of the bottle and the conveyor chain links, the support guide wedge extends into the gap, and the bottle enters the top of the rotating support unit along the support guide wedge.

[0015] Preferably, along the direction from the drive support to the bottle cleaning mechanism, the length of the chain link pressing wedge is greater than that of the support guide wedge; the bottom end of the chain link pressing wedge near the bottle cleaning mechanism is provided with a pressing slope, and the top end of the support guide wedge is provided with a guide slope near the top end of the bottle cleaning mechanism; the rotating support unit includes a support plane, and a support frustum is embedded at the top end of the support plane, the support frustum and the support plane are rotatably connected, and the bottle can be moved to the top end of the support frustum along the guide of the support guide wedge.

[0016] A fire extinguisher bottle cleaning and labeling process, which uses the aforementioned bottle cleaning equipment to clean the fire extinguisher bottle before labeling, includes the following steps:

[0017] As the fire extinguisher cylinders are conveyed along the material conveyor belt, they pass through the cylinder cleaning mechanism and the labeling mechanism in sequence.

[0018] Several fire extinguisher cylinders are retained by the cylinder retention mechanism at the front end of the cylinder cleaning mechanism;

[0019] Only one fire extinguisher cylinder is moved to the cleaning position of the cylinder cleaning mechanism under the drive of the cylinder positioning mechanism, and the cylinder cleaning mechanism cleans the fire extinguisher cylinder located in the cleaning position;

[0020] After cleaning, the fire extinguisher cylinder is released by the cylinder positioning mechanism and then transported by the material conveyor belt to the labeling mechanism for labeling.

[0021] Compared with the prior art, the present invention provides a bottle cleaning device and a fire extinguisher bottle cleaning and labeling process, which has the following beneficial effects:

[0022] 1. This type of bottle cleaning equipment features a bottle positioning mechanism that drives a bottle to move and restricts it to a cleaning position located on one side of the cleaning mechanism as it passes by. While the bottle is in the cleaning position, the cleaning mechanism performs the cleaning process, allowing for subsequent labeling, lamination, and other processing operations. After cleaning is complete, the bottle positioning mechanism resets and releases the cleaned bottle. The cleaned bottle continues to move with the material conveyor belt and detaches from the cleaning position. Simultaneously, the next bottle to be cleaned is released by the bottle interception mechanism and moved and held in the cleaning position by the combined drive of the material conveyor belt and the bottle positioning mechanism. This operation allows for continuous and uninterrupted cleaning of each bottle, ensuring the effectiveness of independent cleaning for each bottle while improving the overall cleaning efficiency of the bottles conveyed on the material conveyor belt.

[0023] 2. This type of bottle cleaning equipment, through the setting of the limiting guide plate, restricts the conveying direction of each bottle on the material conveyor belt, and also limits the number of bottles conveyed side by side to only one. It can effectively ensure that only one bottle enters the operating area of ​​the bottle positioning mechanism and the bottle cleaning mechanism through the bottle interception mechanism, which can avoid the disorder of the bottle conveying and cleaning process. Furthermore, the inclined guide plate set in the operating notch of the limiting guide plate located in the bottle cleaning mechanism tilts from the bottle interception mechanism toward the bottle cleaning mechanism, which can effectively cooperate with the positioning process of the bottle positioning mechanism. This ensures that the bottle is driven by the bottle positioning mechanism and kept in the cleaning position on one side of the bottle cleaning mechanism, thus ensuring effective cleaning of the bottle.

[0024] 3. In this type of bottle cleaning equipment, the cleaning sleeve can be separated from the cleaning installation roller, so that the cleaning sleeve can be replaced in time according to the cleanliness of the cleaning sleeve during use. The structure of the intercepting cone is spindle-shaped, so that the elastic material of the intercepting cone can avoid damage to the bottle body. Under the extension action of the moving end of the intercepting cylinder, the distance between the previous bottle body to be released and the next bottle body to be intercepted is gradually increased through the spindle-shaped structure, thereby separating the previous bottle body to be released and the next bottle body to be intercepted.

[0025] 4. In this type of bottle cleaning equipment, the movable end of the positioning drive cylinder can drive the drive support to move the positioning wedge, positioning drive turntable, and positioning drive motor closer to the bottle cleaning mechanism. Through the setting of the positioning slope of the positioning wedge and the setting of the arc surface of the positioning drive turntable, the bottle can be embedded in the middle area of ​​the positioning wedge and the positioning drive turntable, and the bottle is driven to move closer to the bottle cleaning mechanism until it is held in the cleaning position. Under the power output of the positioning drive motor, the positioning drive turntable can drive the bottle to rotate in the cleaning position relative to the cleaning sleeve and rotate in the opposite direction, strengthening the interference between the bottle and the cleaning sleeve, and effectively positioning the bottle in the cleaning position to ensure the cleaning effect of the bottle.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a bottle cleaning device and a fire extinguisher bottle cleaning and labeling process.

[0039] Example 1:

[0040] Please see Figures 1-10A bottle cleaning device includes a cleaning mounting base 1, which is installed at the bottom end of a material conveyor belt 2. The cleaning mounting base 1 extends from both ends of the material conveyor belt 2 and is respectively provided with a bottle positioning mechanism 3 and a bottle cleaning mechanism 4. A bottle interception mechanism 6 is provided on the side of the material conveyor belt 2 and at the front end of the bottle cleaning mechanism 4. The bottle interception mechanism 6 can intercept several bottles conveyed from the material conveyor belt 2 on a side away from the bottle cleaning mechanism 4. The bottle positioning mechanism 3 can drive a bottle to move and maintain it in a cleaning position located on the side of the bottle cleaning mechanism 4. The bottle is cleaned by the bottle cleaning mechanism 4 in the cleaning position. After cleaning a bottle, the bottle positioning mechanism 3 resets, and the cleaned bottle continues to move with the material conveyor belt 2 and detaches from the cleaning position. The next bottle to be cleaned is released by the bottle interception mechanism 6 and is driven by the material conveyor belt 2 and the bottle positioning mechanism 3 to move and maintain in the cleaning position.

[0041] In use, several bottles (such as fire extinguisher bottles or other cylindrical bottles) to be cleaned are placed on the upper surface of the material conveyor belt 2. The material conveyor belt 2 transports the bottles sequentially. During transport, the bottle-retaining mechanism 6 retains each bottle on the side away from the bottle-cleaning mechanism 4. The bottle-retaining mechanism 6 releases one bottle at a time, allowing it to continue moving towards the bottle-cleaning mechanism 4 (this movement is still facilitated by the material conveyor belt 2). The bottle-positioning mechanism 3 detects when a bottle passes by (this detection is performed by a sensor; the sensor can be a visual sensor or a laser blocking sensor, both common existing technologies, and will not be discussed further here). (To be elaborated), the bottle is driven to move and is kept in a cleaning position located on one side of the bottle cleaning mechanism 4. The bottle is cleaned by the bottle cleaning mechanism 4 in the cleaning position, which facilitates subsequent processing operations such as labeling and lamination after cleaning. After the bottle in the cleaning position is cleaned, the bottle positioning mechanism 3 resets and releases the cleaned bottle. The cleaned bottle continues to move with the material conveyor belt 2 and is removed from the cleaning position. At the same time, the next bottle to be cleaned is released by the bottle interception mechanism 6 and is driven by the material conveyor belt 2 and the bottle positioning mechanism 3 to move and be kept in the cleaning position. In this way, the cleaning operation of each bottle can be carried out continuously and without interruption, which can ensure the effectiveness of cleaning each bottle independently while improving the cleaning efficiency of the bottles conveyed on the entire material conveyor belt 2.

[0042] Example 2:

[0043] Please see Figures 1-10The difference from the above embodiment is that the material conveyor belt 2 is respectively equipped with limit guide plates 5 on its side, and each bottle conveyed by the material conveyor belt 2 can be conveyed under the restriction of each limit guide plate 5; the part of the limit guide plate 5 above the cleaning mounting base 1 is provided with an operation notch, and the bottle positioning mechanism 3 and the bottle cleaning mechanism 4 can respectively extend into the operation notch to perform the operation; the operation notch of the limit guide plate 5 located in the bottle cleaning mechanism 4 is provided with an inclined guide plate 51, and the inclined guide plate 51 is inclined from the bottle intercepting mechanism 6 toward the bottle cleaning mechanism 4.

[0044] In practical use, the setting of the limiting guide plate 5 restricts the conveying direction of each bottle on the material conveyor belt 2, and also limits the number of bottles conveyed side by side to only one. This effectively ensures that only one bottle enters the operating area of ​​the bottle positioning mechanism 3 and the bottle cleaning mechanism 4 through the bottle interception mechanism 6, thus avoiding disorder in the bottle conveying and cleaning process. Furthermore, the inclined guide plate 51 set in the operating notch of the limiting guide plate 5 located in the bottle cleaning mechanism 4 tilts from the bottle interception mechanism 6 toward the bottle cleaning mechanism 4, which can effectively cooperate with the positioning process of the bottle positioning mechanism 3. This ensures that the bottle is kept in the cleaning position on one side of the bottle cleaning mechanism 4 after being driven by the bottle positioning mechanism 3, thus ensuring effective cleaning of the bottle.

[0045] The material conveyor belt 2 includes a conveyor support 21, inside which are arranged several support sprockets 22, and at one end of the conveyor support 21 is a drive sprocket 23. A conveyor chain 24 is arranged on the outside of each support sprocket 22 and drive sprocket 23. The conveyor chain 24 includes several conveyor links 241, each of which includes a link plate. An outer shaft and an embedded shaft are respectively arranged on both sides of the link plate. The embedded shaft of one conveyor link 241 and the outer shaft of another conveyor link 241 can form a link shaft together. Two adjacent conveyor links 241 can be rotatably connected through the combined link shaft.

[0046] A drive motor 25 is provided on one side of the drive sprocket 23. A drive gear 251 is fixedly provided on the output shaft of the drive motor 25. A driven gear 231 is coaxially fixed on one end of the drive sprocket 23. The drive gear 251 and the driven gear 231 are connected and driven by a transmission belt 252. The support sprocket 22 can fit against the bottom surface of the link plate of the passing conveyor link 241 to support the passing conveyor link 241. The drive sprocket 23 can mesh with the combined link shaft of the passing conveyor link 241 to drive the passing conveyor link 241 to move.

[0047] In practical use, the entire conveyor belt 24 is composed of several conveyor links 241 connected end to end in sequence. The embedded shaft of the current conveyor link 241 and the outer shaft of the previous conveyor link 241 can jointly form a link shaft, and the outer shaft of the current conveyor link 241 and the embedded shaft of the next conveyor link 241 can jointly form a link shaft, allowing the current conveyor link 241 to rotate around the link shafts formed by the two sides (within the limitation of the deformation range of the entire conveyor belt 24). The angle between two adjacent conveyor links 241 can be changed within a corresponding range, thus enabling... The support sprockets 22 and 23 are well-fitted to their outer shapes and are supported by the bottom surface of the link plate of the conveyor link 241. The power output from the drive motor 25 is transmitted through the transmission belt 252 between the drive gear 251 and the driven gear 231 to drive the drive sprocket 23 to rotate. Since the drive sprocket 23 meshes with the link shaft of the conveyor link 241, it drives the conveyor link 241 to move, thus driving the entire conveyor belt 24 to move in a cycle.

[0048] Example 3:

[0049] Please see Figures 1-10 The difference from the above embodiment is that the bottle cleaning mechanism 4 includes a cleaning support 41, a cleaning mounting roller 42 is rotatably mounted on the top of the cleaning support 41, a cleaning drive motor 43 is installed inside the cleaning support 41, the cleaning drive motor 43 is poweredly connected to the cleaning mounting roller 42, a cleaning sleeve 44 is sleeved on the outside of the cleaning mounting roller 42, and the cleaning sleeve 44 can be separated from the cleaning mounting roller 42; the bottle interception mechanism 6 includes an interception lifting bracket 61, an interception cylinder 62 is installed at the top of the interception lifting bracket 61, and an interception cone 63 is installed at the movable end of the interception cylinder 62, the interception cone 63 being made of elastic material.

[0050] In practical use, the cleaning sleeve 44 can be separated from the cleaning installation roller 42, so that the cleaning sleeve 44 can be replaced in time according to the cleanliness of the cleaning sleeve 44. The structure of the intercepting cone 63 is spindle-shaped (the structure is thin at both ends and thick in the middle). The elastic material of the intercepting cone 63 (elastic material such as rubber and silicone) can prevent the intercepting cone 63 from damaging the bottle body. Under the extension action of the moving end of the intercepting cylinder 62, the distance between the previous bottle body that needs to be released and the next bottle body that needs to be intercepted is gradually increased through the spindle-shaped structure, thereby separating the previous bottle body that needs to be released and the next bottle body that needs to be intercepted. This ensures that only one bottle body can enter the operating area of ​​the bottle positioning mechanism 3 and the bottle cleaning mechanism 4 through the bottle body intercepting mechanism 6.

[0051] In practical use, a structure that can automatically clean the cleaning sleeve 44 can also be set on the side of the cleaning sleeve 44 away from the bottle positioning mechanism 3 (the automatic cleaning structure is a common technical solution in the prior art, which can be set with two sub-structures: sewage squeezing and clean water input, squeezing out the sewage inside the cleaning sleeve 44 and adding clean water, continuously maintaining the clean state of the cleaning sleeve 44), so as to maintain the clean state of the cleaning sleeve 44. The cleaning installation roller 42 can be driven to rotate by the cleaning drive motor 43, thereby driving the cleaning sleeve 44 to rotate and interfering with the bottle body that is restricted in the cleaning position, thus cleaning the bottle body that is restricted in the cleaning position.

[0052] The bottle positioning mechanism 3 includes a positioning support 31, a driving support 32 slidably disposed on the top of the positioning support 31, and a positioning driving cylinder 33 disposed on the top of the positioning support 31 and on the side of the driving support 32 away from the bottle cleaning mechanism 4; a positioning wedge 321, a positioning driving turntable 322 and a positioning driving motor 323 are disposed on the top of the driving support 32, the positioning driving motor 323 is rotatably connected to the positioning driving turntable 322, and a positioning inclined surface is disposed on the side of the positioning wedge 321 near the bottle cleaning mechanism 4 and near the side of the positioning driving turntable 322.

[0053] In practical use, the movable end of the positioning drive cylinder 33 can drive the drive support 32 to slide on the top of the positioning support 31, causing the positioning wedge 321, the positioning drive turntable 322, and the positioning drive motor 323 set on the top of the drive support 32 to move towards the end closer to the bottle cleaning mechanism 4. Through the setting of the positioning slope of the positioning wedge 321 and the setting of the arc surface of the positioning drive turntable 322, the bottle body can be embedded in the middle area of ​​the positioning wedge 321 and the positioning drive turntable 322, and the bottle body is driven to move towards the end closer to the bottle cleaning mechanism 4 until it is held in the cleaning position. Under the power output of the positioning drive motor 323, the positioning drive turntable 322 can drive the bottle body to rotate in the cleaning position relative to the cleaning sleeve 44 and rotate in the opposite direction, strengthening the interference between the bottle body and the cleaning sleeve 44, and effectively positioning the bottle body in the cleaning position to ensure the cleaning effect of the bottle body.

[0054] In practical use, the positioning wedge 321 can be replaced with another positioning drive turntable 322. Through the arc-shaped surface setting of the two positioning drive turntables 322, the bottle body is embedded in the middle area of ​​the two positioning drive turntables 322 and continues to move towards the bottle body cleaning mechanism 4 until it is held in the cleaning position. Under the power output of the positioning drive motor 323, at least one positioning drive turntable 322 actively rotates (when one positioning drive turntable 322 actively rotates, the other positioning drive turntable 322 can be forced to rotate; when both positioning drive turntables 322 rotate, the positioning drive motor 323 simultaneously outputs power to the two positioning drive turntables 322, and the two positioning drive turntables 322 rotate in the same direction), driving the bottle body to rotate in the opposite direction relative to the cleaning sleeve 44 in the cleaning position, thereby cleaning the bottle body.

[0055] Example 4:

[0056] Please see Figures 1-10 The difference from the above embodiment is that the distance between the two support sprockets 22 located on both sides of the bottle positioning mechanism 3 is greater than the width of the bottle positioning mechanism 3; a separation and introduction mechanism 7 is provided at the bottom end of the drive support 32 near the bottle cleaning mechanism 4. The separation and introduction mechanism 7 includes a chain link pressing wedge plate 71, a support and introduction wedge plate 72, and a rotating support unit 73; during the extension and retraction of the movable end of the positioning drive cylinder 33, the separation and introduction mechanism 7 can move closer to and further away from the side near the bottle cleaning mechanism 4 in sync with the drive support 32.

[0057] As the chain link pressing wedge 71 approaches the bottle cleaning mechanism 4, the chain link pressing wedge 71 can gradually press down several conveyor chain links 241 that are in contact with the chain link pressing wedge 71, creating a gap between the bottom of the bottle and the conveyor chain links 241. The support guide wedge 72 lags behind the chain link pressing wedge 71 by one end. After creating a gap between the bottom of the bottle and the conveyor chain links 241, the support guide wedge 72 extends into the gap, and the bottle enters the top of the rotating support unit 73 along the support guide wedge 72.

[0058] Along the direction from the drive support 32 toward the bottle cleaning mechanism 4, the length of the chain link pressing wedge 71 is greater than that of the support guide wedge 72; the bottom end of the chain link pressing wedge 71 near the bottle cleaning mechanism 4 is provided with a pressing slope, and the top end of the support guide wedge 72 near the bottle cleaning mechanism 4 is provided with a guide slope; the rotating support unit 73 includes a support plane 731, and a support frustum 732 is embedded at the top of the support plane 731. The support frustum 732 and the support plane 731 are rotatably connected, and the bottle can move to the top of the support frustum 732 along the guide of the support guide wedge 72.

[0059] In practical use, the sides of the chain link pressing wedge plate 71 are all arc-shaped, and the bottom surface of the chain link pressing wedge plate 71 is a smooth surface. Universal wheels can be set at the bottom of the chain link pressing wedge plate 71 according to the specific usage environment to suppress the chain link pressing wedge plate 71 from scratching and damaging the conveyor chain belt 24. In practical use, the supporting frustum 732 can be set as a structure that rotates freely, or it can be set as a structure that rotates synchronously with the positioning drive turntable 322 (through the power connection between the supporting frustum 732 and the positioning drive turntable 322, and keeping the angular velocity of the rotation of the supporting frustum 732 equal to the angular velocity of the bottle body rotation driven by the positioning drive turntable 322).

[0060] Driven by the extension of the movable end of the positioning drive cylinder 33, the chain link pressing wedge 71 moves closer to the bottle cleaning mechanism 4. Simultaneously, due to the pressing slope of the chain link pressing wedge 71, it gradually presses down several conveyor chain links 241 that are in contact with it, creating a gap between the bottom of the bottle and the conveyor chain links 241. This provides space for the support guide wedge 72 to extend into the bottom of the bottle. This allows the support guide wedge 72 (since the maximum distance between the support guide wedge 72 and the drive support 32 is less than the maximum distance between the chain link pressing wedge 71 and the drive support 32, allowing the support guide wedge 72 to lag behind the chain link pressing wedge 71 as it moves below the bottle) to extend into the gap after it forms a gap. This allows the bottle to move along the guide slope of the support guide wedge 72 and enter the top of the rotating support unit 73. The support platform 732 is positioned above the bottle body, allowing both the support platform 732 and the bottle body to rotate together with the positioning drive turntable 322. This prevents the bottom of the bottle body from sliding between the support platform 732 and the bottle body. By transferring the bottle body to the support platform 732 during the cleaning process, friction between the bottom of the bottle body and the various conveyor links 241 of the continuously conveying material conveyor belt 2 is avoided during the regular cleaning process. This prevents damage to the paint or coating of the bottle body caused by friction (especially during the cleaning of fire extinguisher bottles, where the time interval between the cleaning and painting processes is short, and the paint adhesion on the surface of the fire extinguisher bottle is still low, making it easy to damage the paint when friction occurs between the bottle body and the material conveyor belt 2; and due to the soft material of the cleaning sleeve 44, the cleaning process of the cleaning sleeve 44 will not damage the paint), ensuring the integrity of the bottle body during the conveying and processing process.

[0061] Example 5:

[0062] A fire extinguisher bottle cleaning and labeling process, which uses a bottle cleaning device as described in any one of Examples 1-4 to clean the fire extinguisher bottle before labeling, includes the following steps:

[0063] During the process of conveying the fire extinguisher cylinder along the material conveyor belt 2, it passes through the cylinder cleaning mechanism 4 and the labeling mechanism 8 in sequence;

[0064] Several fire extinguisher cylinders are intercepted by the cylinder interception mechanism 6 at the front end of the cylinder cleaning mechanism 4;
