Description

Technical Field

[0001] This utility model relates to the field of ultrasonic cleaning equipment technology, specifically to an ultrasonic bottle washing device. Background Technology

[0002] In the production processes of food, pharmaceutical, and chemical industries, various glass and plastic bottles must be thoroughly cleaned before filling to remove impurities, stains, and residues, ensuring the quality and safety of subsequent products. Ultrasonic bottle washing machines consist of an inlet conveyor belt, ultrasonic coarse washing components, an inlet auger component, a water and air rinsing component, an outlet component, and a water and air circulation system. They can automatically complete the entire production process from bottle inlet, ultrasonic coarse washing, fine washing of the outer and inner walls of the bottle, to bottle outlet. In traditional ultrasonic bottle washing equipment, cleaned bottles need to be manually handled or transported by additional equipment to the drying process. This decentralized production mode not only increases the equipment's footprint and investment costs but also extends the production cycle and reduces overall production efficiency. After ultrasonic coarse washing, the bottles converge at the inlet of the auger. If the bottles collide rigidly with the equipment components during this convergence, there is a risk of bottle breakage. Furthermore, during the auger's feeding process, bottles are prone to collision and tipping in the gaps created after feeding, leading to material waste and high equipment maintenance costs. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an ultrasonic bottle washing device. This device integrates ultrasonic cleaning and drying ovens, eliminating the need for manual or additional equipment transfer of bottles after cleaning, thus shortening the production process. The elastic bottle-gathering device avoids rigid collisions between bottles and equipment components, preventing bottle breakage and reducing material waste and equipment maintenance costs. The curved elastic section on the second guide belt can adapt to the squeezing pressure generated by bottle feeding during the feeding process and automatically fill the material gaps formed during feeding, preventing the risk of bottles tipping over and colliding violently.

[0004] An ultrasonic bottle washing device includes an ultrasonic cleaner, a drying oven, and a discharge transfer device connecting the two. The ultrasonic cleaner includes a machine base and a coarse washing tank and a fine washing tank mounted on the machine base. The machine base is also equipped with a conveyor belt. The coarse washing tank contains a coarse washing platform, a bottle inlet auger, and a bottle lifting device. The fine washing tank contains a bottle clamping turntable. The conveyor belt feeds the bottles into the coarse washing platform for coarse washing, then the bottles are conveyed by the bottle inlet auger to the bottle lifting device, and then transferred by the bottle lifting device to the bottle clamping turntable to enter the fine washing tank for fine washing. After fine washing, the bottles are transferred to the discharge transfer device and finally sent to the drying oven. The drying oven has a pre-washing table with a downward-sloping surface and a discharge port at the lower end. On both sides of the pre-washing table are a first guide plate and a second guide plate that are higher than the table surface. At the discharge port, there is an elastic bottle-gathering device that guides the pre-washed bottles to the bottle-feeding auger. The elastic bottle-gathering device consists of a first guide belt and a second guide belt that are elastic and located on both sides of the pre-washing table. The lower end of the first guide belt is arc-shaped and abuts against one side of the bottle-feeding auger. The second guide belt has a curved elastic part that protrudes inward toward the inside of the pre-washing table.

[0005] Furthermore, the bottle lifting device includes a bottle lifting guide column and a rotating sleeve sleeved outside the bottle lifting guide column. The top of the bottle lifting guide column is equipped with a bottle lifting drive motor that drives the rotating sleeve to rotate. The side wall of the bottle lifting guide column has an inclined bottle lifting guide groove. The rotating sleeve has several circumferentially distributed bottle lifting rails vertically arranged. Bottle lifting blocks are slidably connected to the bottle lifting rails. The back of each bottle lifting block has a block guide post embedded in and slidably engaged with the bottle lifting guide groove. During operation, the bottle lifting drive motor drives the rotating sleeve, which in turn rotates the bottle lifting blocks. As the bottle lifting blocks rotate around the bottle lifting guide column, under the cooperation of the block guide post and the bottle lifting guide groove, and constrained by the bottle lifting rails, the bottle lifting blocks simultaneously rise and fall along the bottle lifting rails. When the bottle lifting blocks descend to their lowest point, bottles can be picked up from the bottle inlet auger. When the bottle lifting blocks rise to their highest point, the bottle clamping turntable can grab the bottles on the bottle lifting blocks. This bottle lifting device has a compact structure and requires only one motor to achieve synchronous lifting and lowering of the bottle lifting block during the rotation of the rotating sleeve, thereby improving bottle feeding efficiency and avoiding high equipment failure rate and maintenance costs caused by an overly complex drive system.

[0006] Furthermore, the upper end of the first guide belt is fixed to the first guide plate of the coarse washing table, and the lower end is bent into an arc shape at the discharge port of the coarse washing table along the bottle feeding direction of the bottle feeding auger and abuts against one side of the bottle feeding auger. The first guide belt is bent into an arc shape, which forms a buffer effect during the bottle feeding process, avoiding the risk of bottle breakage due to rigid impact between the bottle and the bottle feeding auger.

[0007] Furthermore, the bottom of the second guide plate has a notch corresponding to the discharge port. A fixing block is fixed outside the notch in the coarse washing tank. The fixing block has a slider that is elastically connected to it and slides on the surface of the coarse washing table. The upper end of the second guide belt is fixed to the second guide plate, and the lower end is fixedly connected to the slider. The middle section of the second guide belt protrudes inward towards the coarse washing table to form a curved elastic part. The slider can further adapt to the squeezing force generated by the bottle feeding auger driving the bottle, preventing the bottle from getting stuck at the discharge port and making the bottle dropping action smoother.

[0008] Furthermore, a baffle parallel to the surface of the pre-washing station is installed above it. The baffle is positioned slightly above the overall height of the bottle (e.g., 2-3 mm) to allow the bottle to pass smoothly through the pre-washing station and into the discharge port, while also preventing the bottle from tipping over.

[0009] Furthermore, a first receiving port is provided on the side wall of the washing tank at the discharge position of the bottle lifting device, and a second receiving port is provided on the side wall of the washing tank at the corresponding position of the discharge transfer device. Specifically, the bottle clamping turntable in the washing tank precisely aligns with the discharge position of the bottle lifting device and the inlet position of the discharge transfer device through the first and second receiving ports, respectively, to avoid bottles getting stuck or colliding at the transfer nodes and to improve the smoothness of equipment operation.

[0010] Furthermore, the discharge and transfer device includes a discharge dial plate, a transfer dial plate, and a drying oven guide trough, all mounted on the machine platform to receive the finely washed bottles from the bottle-clamping turntable. The discharge dial plate and the transfer dial plate are each equipped with several grooves that fit the bottles. One side of the discharge dial plate has a discharge guide block that forms a discharge guide trough with a clearance fit. The discharge guide block has an arc-shaped guide portion that guides the bottles from the bottle-clamping turntable into the discharge guide trough. One side of the transfer dial plate has a transfer guide block that forms a transfer guide trough with a clearance fit. The transfer guide block has a transfer guide plate with a protruding guide portion that guides the bottles from the discharge guide trough into the transfer guide trough. The drying oven guide trough is connected to the outlet end of the transfer guide trough and guides the bottles into the drying oven. The discharge transfer device adopts a structure design that combines a dial and a guide block, which enables the bottles to transition smoothly at each transfer node, effectively preventing the bottles from tipping over, colliding, or getting stuck during the transfer process, and ensuring that the bottles can smoothly enter the drying oven after fine washing.

[0011] Compared with the prior art, the advantages of this utility model are as follows: The equipment combines ultrasonic cleaning and drying oven into an integrated structure, eliminating the need for manual transfer or additional equipment transfer of bottles after cleaning, thus shortening the production process; an elastic bottle-gathering device is set at the discharge port of the coarse washing table, and the arc-shaped structure of the first guide belt and the curved elastic part of the second guide belt form a flexible guide channel. When the bottle passes through, the elastic guide belt can adapt to the deformation of the bottle diameter, avoiding rigid collision between the bottle and the equipment parts, preventing the risk of bottle breakage, and reducing material waste and equipment maintenance costs; the curved elastic part on the second guide belt can adapt to the squeezing pressure generated by the bottle feeding during the feeding process of the coarse washing table and cause the bottle to automatically fill the material gap formed during the feeding process, preventing the risk of bottles tipping over and violent collision.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] The specific embodiments of this utility model will now be described with reference to the accompanying drawings: like Figure 1-5As shown, an ultrasonic bottle washing device includes an ultrasonic cleaner, a drying oven 1, and a discharge transfer device 2 connecting the two. The ultrasonic cleaner includes a machine base 3 and a coarse washing tank 4 and a fine washing tank 5 mounted on the machine base 3. The machine base 3 is also equipped with a conveyor belt 6. The coarse washing tank 4 is equipped with a coarse washing platform 7, a bottle inlet auger 8, and a bottle lifting device 9. The fine washing tank 5 is equipped with a bottle clamping turntable 10. The conveyor belt 6 feeds the bottles into the coarse washing platform 7 for coarse washing, and then through the bottle inlet auger 8 to the bottle lifting device 9. After being transferred by the bottle lifting device 9 to the bottle clamping turntable 10, the bottles enter the fine washing tank 5 for fine washing and are then transferred to the discharge transfer device 2. The bottles are then sent to the drying oven 1. The surface of the coarse washing table 7 is inclined downwards and has a discharge port at the lower end of the table. On both sides of the coarse washing table 7, there are first guide plates 11 and second guide plates 12 that are higher than the table surface. At the discharge port, there is an elastic bottle-gathering device that guides the coarsely washed bottles to the bottle-feeding auger 8. The elastic bottle-gathering device consists of a first guide belt 13 and a second guide belt 14 that are elastic and located on both sides of the coarse washing table 7. The lower end of the first guide belt 13 is arc-shaped and abuts against one side of the bottle-feeding auger 8. The second guide belt 14 has a curved elastic part 15 that protrudes inwards from the coarse washing table 7. Furthermore, the coarse washing tank 4 has a bottle-feeding guide groove 36 that accommodates the bottles and abuts against one side of the bottle-feeding auger 8. Specifically, the coarse washing tank 4 is equipped with an ultrasonic generator to perform ultrasonic coarse washing on the bottles, initially removing impurities and residues inside the bottles. The fine washing tank 5 is equipped with spray needles that work in conjunction with the bottle clamping turntable 10 to perform water vapor rinsing on the bottles for further fine washing. The water inlet action of the coarse washing tank 4 and the fine washing tank 5, the bottle clamping mechanism on the bottle clamping turntable 10, and the water turning and pouring action are all technically mature in the field and do not involve the technical problem that this utility model aims to solve, so they will not be described in detail here.

[0019] In this embodiment, the bottle lifting device 9 includes a bottle lifting guide post 16 and a rotating sleeve 17 sleeved outside the bottle lifting guide post 16. The top of the bottle lifting guide post 16 is also provided with a bottle lifting drive motor 18 that drives the rotating sleeve 17 to rotate. The side wall of the bottle lifting guide post 16 is provided with an inclined bottle lifting guide groove 19. The rotating sleeve 17 is provided with a plurality of bottle lifting slide rails 20 arranged in a circular pattern. The bottle lifting slide rails 20 are provided with bottle lifting blocks 21 that are slidably connected to them. The back of the bottle lifting block 21 is provided with a block guide post 22 that is embedded in the bottle lifting guide groove 19 and slidably cooperates with it. During the operation of the bottle lifting device 9, the bottle lifting drive motor 18 drives the rotating sleeve 17 to rotate the bottle lifting block 21. As the bottle lifting block 21 rotates around the bottle lifting guide column 16, under the cooperation of the guide column 22 and the bottle lifting guide groove 19, and the constraint of the bottle lifting rail 20, the bottle lifting block 21 simultaneously rises and falls along the bottle lifting rail 20. When the bottle lifting block 21 descends to its lowest point, it can be picked up from the bottle inlet auger 8. When the bottle lifting block 21 rises to its highest point, the bottle clamping turntable 10 can grab the bottle on the bottle lifting block 21. This bottle lifting device 9 has a compact structure and only requires one motor to achieve the synchronous lifting and lowering movement of the bottle lifting block 21 during the rotation of the rotating sleeve 17, improving bottle feeding efficiency and avoiding high equipment failure rate and maintenance costs due to an overly complex drive system.

[0020] In this embodiment, the upper end of the first guide belt 13 is fixed to the first guide plate 11 of the coarse washing table 7, and the lower end is bent into an arc shape at the discharge port of the coarse washing table 7 along the bottle feeding direction of the bottle feeding auger 8 and abuts against one side of the bottle feeding auger 8. The first guide belt 13 is bent into an arc shape, which forms a buffer effect during the bottle feeding process, avoiding the risk of bottle breakage due to rigid impact between the bottle and the bottle feeding auger 8.

[0021] In this embodiment, the bottom of the second guide plate 12 is provided with a notch corresponding to the discharge port. A fixing block 23 is fixed outside the notch in the coarse washing tank 4. A slider 24 is provided on the fixing block 23 and is elastically connected to it and slidably disposed on the table surface of the coarse washing table. The upper end of the second guide belt 14 is fixed to the second guide plate 12, and the lower end is fixedly connected to the slider 24. The middle section of the second guide belt 14 protrudes towards the inner side of the coarse washing table 7 to form a curved elastic part 15. The second guide belt 14 cooperates with the slider 24 elastically connected to the fixing block 23. When the bottle feeding auger 8 feeds the bottle, the slider 24 can further adapt to the squeezing force generated by the bottle feeding auger 8 driving the bottle. When feeding the bottle, the slider 24 moves towards the fixing block 23 under the action of the squeezing force to avoid the bottle, so that the bottle can fall smoothly into the groove of the bottle feeding auger 8. After the bottle is fed, the slider 24 immediately returns to its original position under the action of elasticity to avoid the bottle getting stuck at the discharge port, making the bottle dropping action smoother.

[0022] In this embodiment, a baffle 25 parallel to the surface of the coarse washing table 7 is provided above it. The baffle 25 is slightly higher than the overall height of the bottle (e.g., 2-3 mm) from the surface of the coarse washing table 7, so that the bottle can pass smoothly through the coarse washing table 7 and enter the discharge port, while also preventing the bottle from tipping over.

[0023] In this embodiment, a first receiving port 26 is provided on the side wall of the washing tank 5 at the discharge position of the bottle lifting device 9, and a second receiving port 27 is provided on the side wall of the washing tank 5 at a corresponding position to the discharge transfer device 2. Specifically, the bottle clamping turntable 10 in the washing tank 5 precisely connects with the discharge position of the bottle lifting device 9 and the inlet position of the discharge transfer device 2 through the first receiving port 26 and the second receiving port 27, respectively, to avoid bottles getting stuck or colliding at the transfer nodes and to improve the smoothness of equipment operation.

[0024] In this embodiment, the discharge transfer device 2 includes a discharge dial 28 and a transfer dial 29 mounted on the machine base 3 to receive the finely washed bottles from the bottle clamping turntable 10, and a drying oven guide trough 30 to guide the bottles from the transfer dial 29 to the drying oven 1. The discharge dial 28 and the transfer dial 29 are provided with several grooves that are adapted to the bottles on their periphery. The discharge dial 28 is provided with a discharge guide block 31 on one side, which is fitted with the discharge guide to form a discharge guide trough. The discharge guide block 31 is provided with an arc-shaped guide part 32 that guides the bottles on the bottle clamping turntable 10 into the discharge guide trough. The transfer dial 29 is provided with a transfer guide block 33 on one side, which is fitted with the transfer guide to form a transfer guide trough. The transfer guide block 33 is provided with a transfer guide piece 34. The transfer guide piece 34 is provided with a protruding guide part 35 that guides the bottles from the discharge guide trough into the transfer guide trough. The drying oven guide trough 30 is connected to the outlet end of the transfer guide trough and guides the bottles into the drying oven 1. The discharge transfer device 2 adopts a structure design that combines a dial and a guide block. The dial is used to position the bottle, and with the guidance of the arc-shaped guide part 32 and the raised guide part 35, the bottle can be smoothly transferred at each transfer node. This effectively avoids the bottle from tipping over, colliding or getting stuck during the transfer process, and ensures that the bottle can smoothly enter the drying oven 1 after fine washing.

[0025] Description of the working principle of this utility model: Conveyor belt 6 sends the bottles into the coarse washing table 7. As the bottles slide down the inclined surface of the coarse washing table 7 to the discharge port, the elastic buffering effect of the first guide belt 13 and the second guide belt 14 reduces the impact force of the bottles falling, reduces the rigid collision between the bottles and the equipment parts, and reduces the risk of bottle breakage. After coarse washing, the bottles are sent to the bottle lifting device 9 through the bottle inlet auger 8, and then transferred to the bottle clamping turntable 10 to enter the fine washing tank 5 for fine washing. After fine washing, the bottles are transferred to the discharge transfer device 2 and finally sent to the drying oven 1.

[0026] The beneficial effects of this utility model are as follows: The equipment combines the ultrasonic cleaning and drying oven 1 into an integrated structure, eliminating the need for manual transfer or additional equipment transfer of bottles after cleaning, thus shortening the production process; an elastic bottle-gathering device is set at the feeding port of the coarse washing table 7, and the arc-shaped structure of the first guide belt 13 and the curved elastic part 15 of the second guide belt 14 form a flexible guide channel. When the bottle passes through, the elastic guide belt can adapt to the deformation of the bottle diameter, avoiding rigid collision between the bottle and the equipment parts, preventing the risk of bottle breakage, and reducing material waste and equipment maintenance costs; the curved elastic part 15 on the second guide belt 14 can adapt to the squeezing pressure generated by the bottle feeding during the feeding process of the coarse washing table 7 by its own elasticity and cause the bottle to automatically fill the material gap formed during the feeding process, preventing the risk of bottles tipping over and violent collision.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
