Description

Technical Field

[0001] This utility model relates to the field of wine bottle cleaning, specifically a wine bottle cleaning device before baijiu (Chinese liquor) bottling. Background Technology

[0002] As we all know, baijiu is one of the most frequently consumed alcoholic beverages at people's dinner tables, and its sales volume is enormous. Currently, baijiu is usually bottled, and the bottles need to be cleaned before bottling. This includes cleaning the exterior and interior of the bottle. Currently, the common method for cleaning the interior of the bottle is to first clamp the bottle and then spray cleaning liquid into the bottle through a nozzle to clean the inside. However, the problem with this method is that the cleaning liquid needs to be manually poured out of the bottle after cleaning, which is very troublesome and increases the workload of the operators.

[0003] According to the published patent 202122364542.5, a liquor bottle cleaning device before bottling, it includes a bottle cleaning box, a rotating motor, a support base, a flipping rod, a flipping arm, a cylinder, a cylinder fixing plate, a movable bottle clamping plate, and a fixed bottle clamping plate. There are two sets of support bases. The rotating motor is fixedly installed on the side of the right support base and connected to the flipping rod. There are two sets of flipping arms, fixed to both ends of the flipping rod. The outer ends of the flipping arms are fixed to the fixed bottle clamping plate. There are two sets of cylinders and cylinder fixing plates, with one set of cylinders on each cylinder fixing plate. The cylinder fixing plate is fixed to the corresponding flipping arm. The telescopic ends of the two sets of cylinders are connected to the movable bottle clamping plate. Anti-slip pads are fixed to the inner sides of both the movable and fixed bottle clamping plates. The bottle cleaning box has multiple sets of nozzles corresponding to the bottle positions. This invention simplifies the process of cleaning the inside of the liquor bottle, making its operation more convenient.

[0004] However, traditional baijiu bottle cleaning devices before bottling typically employ a fixed cleaning structure. During cleaning, the bottles are placed in the cleaning station for internal and external rinsing. After cleaning, the motor must be manually activated to adjust the bottle angle, allowing the cleaning solution to flow out naturally by flipping the bottle. The bottle is then manually returned to its initial position. This process requires repeated flipping and returning of the bottle, which is not only labor-intensive and inefficient, but also prone to damage or incomplete cleaning due to operational errors caused by frequent mechanical movements, indirectly increasing production costs and safety risks. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a liquor bottle cleaning device before bottling. This addresses the problem that current traditional liquor bottle cleaning devices typically use a fixed cleaning structure. During cleaning, the bottle is placed in the cleaning station for internal and external rinsing. After cleaning, the motor needs to be manually started to adjust the angle of the bottle. The bottle is then flipped to allow the internal cleaning fluid to flow out naturally, and then it is manually returned to its initial state. During this process, the operator needs to repeatedly flip and return the bottle, which is not only labor-intensive and inefficient, but also prone to bottle breakage or incomplete cleaning due to operational errors during frequent mechanical movements, indirectly increasing production costs and safety risks.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a liquor bottle cleaning device before bottling is designed, including a device base plate. A set of support rods is installed on both sides of the top of the device base plate. A side plate is fixed to the top of each set of support rods. A conveyor belt is arranged between the two side plates. A bottle limiting component is provided on the surface of the conveyor belt. A circular groove is opened in the top of the device base plate. A telescopic cylinder is installed at the bottom of the circular groove. A device base box is fixed to the piston rod at the top of the telescopic cylinder. A cleaning component is provided on the top of the device base box.

[0007] Preferably, the cleaning assembly includes a sealing plate, which is installed at the top of the bottom box of the device, and a liquid pump is installed at the rear end of the top of the sealing plate.

[0008] Preferably, one end of the liquid pump is connected to a first connecting pipe, the end of the first connecting pipe away from the liquid pump is a sealed structure, and the other end of the liquid pump is connected to an L-shaped pipe, the other end of the L-shaped pipe passing through the sealing plate and extending into the inner bottom of the device base box.

[0009] Preferably, the top of the first connecting pipe is connected to a plurality of second connecting pipes, the tops of the plurality of second connecting pipes pass through the bottom box of the device and are connected to the rotating ring end of the rotary joint. The rotating ring end is machined with external threads, and the second connecting pipes are machined with internal threads. The connection is achieved by thread engagement.

[0010] Preferably, the stationary ring end at the top of the rotary joint is connected to a third connecting pipe, the top of the third connecting pipe is connected to a nozzle, and a plurality of cleaning bristles are fixed around the outer wall of the nozzle.

[0011] Preferably, a first gear is passed through the exterior of each of the plurality of rotary joints, and the position of the first gear through the rotary joint is fixed. The plurality of first gears mesh with each other, and the first gear at the foremost end meshes with a second gear.

[0013] Preferably, the bottle limiting assembly includes a threaded groove, a threaded post is threadedly connected inside the threaded groove, a limiting cylinder is fixed at one end of the threaded post extending out of the threaded groove, a plurality of fixed cylinders are installed on the inner wall of the limiting cylinder, a movable rod passes through the inside of the fixed cylinder, a spring is fixed at one end of the movable rod located inside the fixed cylinder, and a clamping plate is fixed at one end of the movable rod extending out of the fixed cylinder.

[0014] Preferably, the front surface of the device's bottom box is connected to one end of a liquid pipe at both the top and bottom, and the other end of the liquid pipe is detachably connected to a pipe cap.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model combines a liquid pump, a drive motor, and a rotary joint to achieve continuous conveying of multiple wine bottles via a conveyor belt. When a bottle moves to the cleaning station, a telescopic cylinder below simultaneously drives multiple rotary joints and nozzles to extend into the bottle with its opening facing downwards. At this time, the nozzles use a bottom-up rinsing method, utilizing the combined effect of water flow, gravity, and pressure to allow the cleaning liquid to flow directly from the bottle opening. This completely avoids the tedious operation of traditional manual inversion and pouring, improving cleaning efficiency and reducing labor intensity. Moreover, the device uses multiple gear drives to achieve multi-axis linkage rotation when the nozzles and cleaning brushes penetrate deep into the bottle. This not only allows the nozzles to spray cleaning liquid while simultaneously driving the cleaning brushes to rotate at high speed and scrub the bottle wall, but also supports multiple... The synchronized operation of the bottles ensures that the inner wall of each bottle is thoroughly cleaned, improving the cleanliness of the bottles and production efficiency before bottling. It solves the technical problems of traditional bottle cleaning devices before bottling, which usually use a fixed cleaning structure. During cleaning, the bottles are placed in the cleaning station for internal and external rinsing. After cleaning, the motor needs to be manually started to adjust the angle of the bottle. The internal cleaning solution is allowed to flow out naturally by flipping the bottle, and then it is manually returned to the initial state. During this process, the staff needs to repeatedly flip and return the bottle. This is not only labor-intensive and inefficient, but also prone to bottle breakage or incomplete cleaning due to operational errors in the frequent mechanical movements, which indirectly increases production costs and safety risks.

[0017] 2. This utility model combines a threaded post, a limiting cylinder, and a fixed cylinder. When the bottle is inserted into the limiting cylinder, the fixed cylinder inside the limiting cylinder automatically moves the moving rod through the elastic potential energy of its built-in spring. This causes the clamping plate to fit tightly against the outer wall of the bottle, achieving self-adaptive clamping and fixing. This ensures the bottle remains stable during cleaning or processing. At the same time, one end of the limiting cylinder forms a detachable connection structure with the threaded groove on the conveyor belt surface through the threaded post. This allows users to quickly change to a suitable limiting cylinder for different sized bottles. The disassembly and assembly can be completed simply by rotating the threaded post, without the need for complex tools or machine stoppage adjustments, thus improving the versatility and flexibility of the device.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] Example 1: A bottle cleaning device for baijiu (Chinese liquor) before bottling, see [link / reference]. Figures 1 to 3The device includes a base plate 1, with a set of support rods 101 installed on both sides of the top of the base plate 1. Each set of support rods 101 has a side plate 2 fixed to its top. A conveyor belt 201 is arranged between the two side plates 2. A bottle limiting component is provided on the surface of the conveyor belt 201. A circular groove 219 is opened on the top of the base plate 1. A telescopic cylinder 220 is installed at the bottom of the circular groove 219. A device base box 203 is fixed to the piston rod on the top of the telescopic cylinder 220. A cleaning component is provided on the top of the device base box 203. First, multiple bottles to be cleaned are inserted into the corresponding limiting cylinders 202. The limiting function of the limiting cylinders 202 achieves the initial fixation of the bottles. Then, the conveyor belt 201 is started, and its transmission mechanism drives the limiting cylinders 202 and the... The bottles move synchronously. When a bottle reaches the cleaning station (i.e., the position perpendicular to multiple nozzles 210), the conveyor belt 201 automatically stops. At this time, the telescopic cylinder 220 is activated, and the piston rod's telescopic movement drives the device base 203 to move upwards as a whole. This, in turn, causes the rotary joint 207, the third connecting pipe 208, and the nozzles 210 to rise synchronously, allowing the nozzles 210 and cleaning bristles 209 to extend into the bottle. After the nozzles 210 are in place, the liquid pump 214 is turned on. The liquid pump 214 delivers the cleaning solution in the device base 203 through the first connecting pipe 216 to multiple second connecting pipes 217, and then through the rotary joint 207 into the third connecting pipe 208. Finally, the nozzles 210 inject the solution into the bottle from bottom to top. Inside the bottle, this rinsing method utilizes the combined effect of water flow, gravity, and pressure to allow the cleaning solution to flow directly out of the bottle opening after cleaning, eliminating the need for manual inversion and emptying, thus improving cleaning efficiency and reducing labor intensity. When a deep scrubbing of the bottle's inner wall is required, the drive motor 218 is activated. The drive motor 218 drives the second gear 205 to rotate via the rotating rod 204. The second gear 205 further drives multiple first gears 206 to rotate synchronously. The first gears 206 are connected to the rotary joint 207, thus driving the third connecting pipe 208, the nozzle 210, and the cleaning bristles 209 to achieve multi-axis linkage rotation. During this process, while the nozzle 210 continuously sprays the cleaning solution, the cleaning bristles 209 rotate to clean the inner wall of the bottle. This device performs comprehensive cleaning and supports simultaneous cleaning of multiple bottles, improving the cleanliness of bottles before bottling and overall production efficiency. It solves the technical problems of traditional bottle cleaning devices before bottling, which typically use a fixed cleaning structure. During cleaning, the bottles are placed in the cleaning station for internal and external rinsing. After cleaning, the motor needs to be manually started to adjust the angle of the bottle. The bottle is flipped to allow the internal cleaning solution to flow out naturally, and then it is manually returned to its initial state. During this process, the staff needs to repeatedly flip and return the bottle. This is not only labor-intensive and inefficient, but also prone to bottle breakage or incomplete cleaning due to operational errors during frequent mechanical movements, indirectly increasing production costs and safety risks.

[0024] For details, see Figure 2The cleaning assembly includes a sealing plate 213, which is installed at the top of the bottom box 203 of the device. A liquid pump 214 is installed at the rear end of the top of the sealing plate 213.

[0025] For more details, see Figure 2 One end of the liquid pump 214 is connected to a first connecting pipe 216. The end of the first connecting pipe 216 away from the liquid pump 214 is a sealed structure. The other end of the liquid pump 214 is connected to an L-shaped pipe 215. The other end of the L-shaped pipe 215 passes through the sealing plate 213 and extends into the bottom of the device bottom box 203.

[0026] Further, see Figure 2 The top of the first connecting pipe 216 is connected to multiple second connecting pipes 217. The tops of the multiple second connecting pipes 217 pass through the device base box 203 and are connected to the rotating ring end of the rotary joint 207. The rotating ring end is machined with external threads, and the second connecting pipes 217 are machined with internal threads. The connection is achieved by thread engagement.

[0027] Further, see Figure 1 and Figure 2 The top of the rotary joint 207 is connected to the stationary ring end, which is connected to the third connecting pipe 208. The top of the third connecting pipe 208 is connected to the nozzle 210, and multiple cleaning bristles 209 are fixed around the outer wall of the nozzle 210.

[0028] It is worth noting that, see Figure 1 and Figure 2 Multiple rotary joints 207 are all penetrated by first gears 206, and the penetration position of the first gears 206 and the rotary joints 207 is fixed. The multiple first gears 206 mesh with each other, and the first gear 206 at the foremost end meshes with a second gear 205.

[0029] It is worth noting that, see Figure 2 The second gear 205 has a rotating rod 204 running through it. The bottom of the rotating rod 204 extends into the device base box 203. One end of the rotating rod 204 located in the device base box 203 is connected to the output shaft of the drive motor 218 through a coupling. The drive motor 218 is installed on the top of the sealing plate 213.

[0030] It is worth mentioning that, see Figure 3The bottle limiting assembly includes a threaded groove 304, with a threaded post 305 threadedly connected inside the threaded groove 304. A limiting cylinder 202 is fixed to one end of the threaded post 305 extending out of the threaded groove 304. Multiple fixed cylinders 3 are installed on the inner wall of the limiting cylinder 202. A movable rod 302 passes through the inside of each fixed cylinder 3. A spring 301 is fixed to one end of the movable rod 302 inside the fixed cylinder 3, and a clamping plate 303 is fixed to the other end of the movable rod 302 extending out of the fixed cylinder 3. When the bottle is inserted into the limiting cylinder 202, the fixed cylinders 3 inside the limiting cylinder 202 release elastic potential energy under the pressure of the bottle's outer wall through their built-in springs 301, driving... The movable rod 302 moves axially along the fixed cylinder 3, and the movable rod 302 further drives the clamping plate 303 to fit against the outer wall of the bottle, forming an adaptive clamping force to clamp the bottle. One end of the limiting cylinder 202 is provided with a threaded post 305. The threaded post 305 and the threaded groove 304 pre-set on the surface of the conveyor belt 201 form a detachable threaded connection. According to actual processing needs, users can quickly disassemble the original limiting cylinder 202 and replace it with a matching limiting cylinder 202 by rotating the threaded post 305 for bottles of different sizes or shapes. No special tools are required in this process, and the operation is simple and quick, improving the versatility and flexibility of the device.

[0031] It is worth emphasizing that, see Figure 1 The front surface of the device base box 203 is connected to one end of a liquid pipe 211 at both the top and bottom, and the other end of the liquid pipe 211 is detachably connected to a pipe cap 212.

[0032] It should be noted that in order to accurately align the nozzle 210 with the wine bottle, two sets of sensors can be installed 100mm before and after the cleaning station to detect the arrival and departure signals of the wine bottle. When the rear sensor is triggered (the wine bottle arrives) and the front sensor is not triggered (the subsequent wine bottle has not entered), the PLC determines that the wine bottle is located in the center of the station, thereby achieving accurate alignment between the wine bottle and the nozzle 210.

[0033] The conveyor belt 201 in this application adopts the existing technical solution. The drive part is driven by a servo motor directly driving the conveyor belt 201 through a synchronous pulley. The tensioning wheel automatically adjusts the pretension force through an elastic mechanism to prevent slippage. The mechanical structure, transmission method and parameters (such as motor power, material of conveyor belt 201, etc.) of the motor and tensioning wheel all follow the industry's common standards. The specific implementation details are not within the scope of protection of this application. The focus of this application is that the spray nozzle 210 is automatically extended into the bottle from bottom to top to rinse by the telescopic cylinder 220, eliminating the need for manual turning and pouring operations and reducing labor intensity. At the same time, the spraying of the spray nozzle 210 and the rotation of the cleaning brush 209 are synchronized by the multi-axis linkage gear transmission, which supports the simultaneous operation of multiple wine bottles and the all-round cleaning of the inner wall, effectively improving the cleanliness of the wine bottles before filling and the overall production efficiency.

[0034] When the diameter of the bottle opening to be cleaned is smaller than the diameter of the current nozzle 210, it is necessary to replace it with a smaller nozzle 210 to avoid the problem of not being able to use the cleaning fluid due to size mismatch.

[0035] When using a liquor bottle cleaning device before bottling, multiple bottles to be cleaned are first inserted into corresponding limiting cylinders 202. The limiting cylinders 202 provide initial fixation of the bottles. Then, the conveyor belt 201 is started, and its transmission mechanism drives the limiting cylinders 202 and the bottles to move synchronously. When the bottles reach the cleaning station (i.e., the position perpendicularly aligned with multiple nozzles 210), the conveyor belt 201 automatically stops. At this point, the telescopic cylinder 220 is activated, and the piston rod's telescopic movement drives the device base 203 to move upwards, thereby causing the rotary joint 207, the third connecting pipe 208, and the nozzles 210 to rise synchronously, allowing the nozzles 210 to extend into contact with the cleaning brush bristles 209. After the nozzle 210 is in place, the liquid pump 214 is turned on. The liquid pump 214 delivers the cleaning solution in the device's bottom box 203 to multiple second connecting pipes 217 through the first connecting pipe 216, and then into the third connecting pipe 208 through the rotary joint 207. Finally, the solution is injected into the bottle from the bottom up by the nozzle 210. This rinsing method utilizes the combined effect of water flow, gravity, and pressure to allow the cleaning solution to flow directly out of the bottle opening after cleaning, eliminating the need for manual inversion and emptying, thus improving cleaning efficiency and reducing labor intensity. When a deep scrubbing of the bottle's inner wall is required, the drive motor 218 is started. The drive motor 218 drives the second gear through the rotating rod 204. The second gear 205 rotates, further driving multiple first gears 206 to rotate synchronously. The first gears 206 are connected to the rotary joint 207, thus driving the third connecting pipe 208, nozzle 210, and cleaning brush 209 to achieve multi-axis linkage rotation. During this process, while the nozzle 210 continuously sprays cleaning fluid, the cleaning brush 209 rotates to thoroughly scrub the inner wall of the bottle. This device supports simultaneous cleaning of multiple bottles, improving the cleanliness of the bottles before bottling and overall production efficiency. When the bottle is inserted into the limiting cylinder 202, the fixed cylinder 3 inside the limiting cylinder 202 releases pressure from the outer wall of the bottle through its built-in spring 301. The elastic potential energy is released, driving the moving rod 302 to move axially along the fixed cylinder 3. The moving rod 302 further drives the clamping plate 303 to fit against the outer wall of the bottle, forming an adaptive clamping force to clamp the bottle. One end of the limiting cylinder 202 is provided with a threaded post 305. The threaded post 305 and the threaded groove 304 pre-set on the surface of the conveyor belt 201 form a detachable threaded connection. According to the actual processing needs, the user can quickly disassemble the original limiting cylinder 202 and replace it with a matching limiting cylinder 202 by rotating the threaded post 305 for bottles of different sizes or shapes. No special tools are required in this process, and the operation is simple and quick, improving the versatility and flexibility of the device.
