DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] See also Figures 1-7 A small packaging barrel automatic cleaning and drying device includes a processing box 1, in which a vertically arranged partition 11 is fixed. The partition 11 divides the processing box 1 into an ultrasonic cleaning pool 12, a spray cleaning pool 13, and a drying pool 14 arranged in sequence.

[0041] It also includes a transmission component 2 and a clamp unit 3. The transmission component 2 is assembled in the processing box 1 and is mounted above the ultrasonic cleaning tank 12, the spray cleaning tank 13, and the drying tank 14. The clamp unit 3 is evenly assembled on the transmission component 2 and runs synchronously with the transmission component 2.

[0042] The transmission component 2 includes a mounting shaft 21, a transmission sprocket 22, a transmission chain 23, and a reduction motor 24. Multiple groups of mounting shafts 21 are rotatably installed in the processing box 1. Each group of mounting shafts 21 is fixed with two groups of coaxially arranged transmission sprockets 22. The transmission chain 23 includes two groups and is respectively wound around the two groups of transmission sprockets 22 on each mounting shaft 21. The reduction motor 24 is dynamically connected to one of the groups of mounting shafts 21.

[0043] The clamp unit 3 is assembled between the two groups of transmission chains 23 of the transmission assembly 2 through the connecting rod mechanism 4. The clamp unit 3 clamps the packaging barrel 8 for cleaning.

[0044] The partition plate 11 can isolate the ultrasonic cleaning tank 12, the spray cleaning tank 13 and the drying tank 14 from each other, so as to ensure that the cleaned packaging barrel 8 can complete the corresponding processing work in each processing tank.

[0045] For the transmission assembly 2, when the corresponding mounting shaft 21 is stably operated by the speed reducer motor 24, the transmission sprocket 22 and the chain combination can stably operate each group of transmission sprockets 22 and transmission chains 23. The transmission chain 23 is provided with two groups arranged side by side, which can ensure that the clamp unit 3 is stably assembled on the transmission chain 23.

[0046] The clamp unit 3 can stably clamp the bottom outer wall of the packaging barrel 8 and synchronously operate with the transmission assembly 2, so that the cleaned packaging barrel 8 sequentially passes through the ultrasonic cleaning tank 12, the spray cleaning tank 13 and the drying tank 14. The ultrasonic cleaning tank 12 is filled with a mixture of clean water and detergent, and the submerged packaging barrel 8 is deeply cleaned by the action of ultrasonic waves. After the packaging barrel 8 passes through the ultrasonic cleaning tank 12, it enters the spray cleaning tank 13, and the clean water sprayed from the spray cleaning tank 13 sprays and cleans the inner and outer walls of the packaging barrel 8 to clean the detergent contained therein, so that the packaging barrel 8 meets the packaging cleanliness requirements of health food and special diet food. Then the packaging barrel 8 enters the drying tank 14, the water attached thereto is drained under the action of its own gravity, and clean hot air is introduced to dry it, so as to quickly dry the residual water on the packaging barrel 8, and after output from the processing box 1, it can be used for food packaging.

[0047] In order to ensure that the transmission assembly 2 drives the clamp unit 3 and the packaging barrel 8 to transfer between the processing tanks, ensure that the packaging barrel 8 can stably pass through the top of the partition plate 11, and can be lowered into the corresponding processing tank after entering the corresponding processing tank, so as to facilitate effective processing of the packaging barrel 8, each transmission sprocket 22 includes a guide sprocket according to function. The guide sprocket is arranged above the partition plate 11 and at both ends of the processing box 1, so as to ensure that the transmission chain 23 is arranged and transmitted in a specific direction.

[0048] In order to ensure that the transmission sprocket 22 is arranged in a tight state, the transmission sprocket 22 further includes a tension sprocket and a support sprocket according to function. The support sprocket and the tension sprocket are arranged above the guide sprocket, which can press the transmission sprocket 22 to be in a tight state, so as to ensure that the clamp unit 3 and the packaging barrel 8 are stably transmitted in a set direction.

[0049] In order to ensure that the ultrasonic cleaning tank 12 can ultrasonically clean the packaging barrel 8 transmitted thereto, and facilitate replacement of the water in the ultrasonic cleaning tank 12, the following technical solutions are provided.

[0050] The processing box 1 is also provided with an assembly cavity 15 arranged below the ultrasonic cleaning pool 12, and a plurality of groups of ultrasonic generators 5 are uniformly arranged in the assembly cavity 15 and arranged vertically upward; the top and bottom of the ultrasonic cleaning pool 12 are respectively connected with a water inlet 121 and a water outlet A 122.

[0051] The two sides of the assembly cavity 15 are provided with openings, and the opening positions are provided with cover plates 151; the openings can facilitate the stable installation of the ultrasonic generators 5 in the assembly cavity 15, and the cover plates 151 can seal the assembly cavity 15 to ensure the stable operation of the ultrasonic generators 5 in an isolated environment, and also avoid the transmission of noise generated by the ultrasonic generators 5 to the outside.

[0052] The ultrasonic generators 5 can transmit ultrasonic waves to the ultrasonic cleaning pool 12 above during operation to effectively clean the packaging barrels 8 therein, and the water inlets 121 and the water outlets A 122 can meet the water injection and drainage requirements of the ultrasonic cleaning pool 12.

[0053] In order to ensure that the packaging barrels 8 in the spray cleaning pool 13 can be sprayed and cleaned, and to facilitate the external discharge of the water collected in the spray cleaning pool 13, the following technical solutions are provided.

[0054] A plurality of groups of upper spray pipes 61 and lower spray pipes 62 are arranged in the spray cleaning pool 13, and the upper spray pipes 61 and the lower spray pipes 62 are arranged above and below the packaging barrels 8, respectively; the upper spray pipes 61 and the lower spray pipes 62 are connected with a water supply pump 64 through a water supply pipe 63, and the water supply pump 64 is arranged outside the processing box 1; and the bottom of the spray cleaning pool 13 is connected with a water outlet B 131.

[0055] During the cleaning and drying process of the packaging barrels 8, the packaging barrels 8 are fixed to the clamp unit 3 in a manner that the opening is arranged downward, which can effectively avoid the accumulation of residual water in the packaging barrels 8.

[0056] The water supply pump 64 pressurizes the clean water and delivers it to the upper spray pipes 61 and the lower spray pipes 62 through the water supply pipe 63; the clean water in the upper spray pipes 61 is sprayed downward to mainly clean the outer wall of the packaging barrels 8, and the clean water in the lower spray pipes 62 is sprayed upward to mainly clean the inner wall of the packaging barrels 8.

[0057] The water generated during the spray cleaning process is collected at the bottom of the spray cleaning pool 13 and discharged through the water outlet B 131.

[0058] In order to ensure that the packaging barrels 8 in the drying pool 14 can be dried, and to facilitate the collection and external discharge of the water drained from the packaging barrels 8 at the bottom of the drying pool 14, the following technical solutions are provided.

[0059] The drying pool 14 is equipped with multiple groups of U-shaped air distribution pipes 71 arranged at the bottom and both sides of the treatment box 1, each group of U-shaped air distribution pipes 71 is connected with a gas supply pump 73 through a gas supply pipe 72, and the treatment box 1 is fixedly installed with a gas collecting hood 141 arranged directly above the drying pool 14, and the bottom of the drying pool 14 is connected with a water outlet C142.

[0060] The gas supply pump 73 delivers clean hot air into the U-shaped air distribution pipes 71 through the gas supply pipe 72, the U-shaped air distribution pipes 71 blow hot air to both sides and the bottom of the packaging barrel 8 to perform all-round drying treatment on the packaging barrel 8 arranged with the opening downward to quickly remove the residual water on the packaging barrel 8, and the hot air after drying treatment contains moisture, which can be recycled to the U-shaped air distribution pipes 71 after drying treatment by the gas collecting hood 141.

[0061] The water collected at the bottom of the drying pool 14 can be discharged through the water outlet C142.

[0062] In order to effectively provide the processing efficiency of the device to the packaging barrel 8, the following technical solutions are provided.

[0063] The transmission assembly 2 includes multiple groups arranged side by side, the mounting shafts 21 in the same coaxial arrangement in each group of transmission assemblies 2 are fixedly connected, and each group of transmission assemblies 2 is provided with a group of speed reduction motors 24.

[0064] By adding multiple groups of transmission assemblies 2 arranged side by side, the number of clamp units 3 can be effectively increased, thereby ensuring the number of synchronous cleaning and drying treatment of the packaging barrels 8, and effectively improving the efficiency of the device in processing the packaging barrels 8.

[0065] The mounting shafts 21 in the same coaxial arrangement in each group of transmission assemblies 2 are fixedly connected and synchronously driven by the same speed reduction motor 24, which can ensure the synchronous operation of each group of transmission assemblies 2.

[0066] For the transmission sprocket 22 and the corresponding mounting shaft 21 on the same side of the clamp unit 3, in order to avoid the space motion interference between the clamp unit 3 and the packaging barrel 8 clamped thereby and the mounting shaft 21 when they run to this position, the geometric radius of the transmission sprocket 22 can be increased to enable the clamp unit 3 and the packaging barrel 8 to normally pass through the corresponding mounting shaft 21.

[0067] Alternatively, the transmission sprocket 22 and the mounting shaft 21 at this position are independently designed, that is, each group of transmission sprockets 22 is installed on an independent group of mounting shafts 21, which can also avoid the space motion interference between the mounting shaft 21 and the clamp unit 3 and the packaging barrel 8 due to the through arrangement.

[0068] To ensure that the clamp unit 3 can effectively clamp the packaging barrel 8 without power, drive the packaging barrel 8 to run in the treatment box 1, and facilitate the quick disassembly and assembly of the packaging barrel 8 at the upstream and downstream port positions of the treatment box 1, the following technical solutions are provided.

[0069] The clamp unit 3 comprises an assembly sleeve 31, a telescopic shaft 32, and a plurality of groups of connecting rods A 33, connecting rods B 34, and clamping heads 35 arranged in an annular array. The telescopic shaft 32 is slidingly installed in the assembly sleeve 31. The two ends of the connecting rod A 33 are hingedly connected to the assembly sleeve 31 and the clamping head 35, respectively. The two ends of the connecting rod B 34 are hingedly connected to the telescopic shaft 32 and the clamping head 35, respectively. The telescopic shaft 32 is peripherally sleeved with a supporting spring 36, and the two ends of the supporting spring 36 are abutted with the assembly sleeve 31 and the telescopic shaft 32, respectively.

[0070] In the natural state, the supporting spring 36 can drive the telescopic shaft 32 to slide upward along the assembly sleeve 31, and then make each group of clamping heads 35 shrink inward through the action of the connecting rod A 33 and the connecting rod B 34, thereby stably clamping the outer wall of the packaging barrel 8.

[0071] When the packaging barrel 8 needs to be disassembled from the clamp unit 3 at the upstream and downstream port positions of the treatment box 1, only the telescopic shaft 32 needs to be manually or by a matched cylinder to slide downward (on one side of the packaging barrel 8), thereby making each group of clamping heads 35 expand outward, facilitating the removal of the packaging barrel 8 clamped on the inner side, or clamping the uncleaned packaging barrel 8 into the inner side of the clamping head 35.

[0072] To ensure that the clamp unit 3 can be assembled to the transmission chain 23 of the transmission assembly 2 through the connecting rod mechanism 4, and that the clamp unit 3 can be stably installed at the turning position of the chain, the following technical solutions are provided.

[0073] The assembly sleeve 31 is fixedly connected with an assembly platform 311. The connecting rod mechanism 4 comprises two groups arranged side by side. Each group of the connecting rod mechanism 4 comprises two groups of assembly shafts 41, connecting rods A 42, and connecting rods B 43. The assembly shaft 41 is fixedly connected with the pin shaft of the transmission sprocket 22. The connecting rod A 42 and the connecting rod B 43 are rotatably installed on the two groups of assembly shafts 41, respectively. The connecting rod A 42 and the connecting rod B 43 are hingedly connected to the assembly platform 311 and coaxially arranged.

[0074] The two groups of connecting rod mechanisms 4 can stably install the clamp unit 3 on the transmission sprocket 22. When the transmission chain 23 is at the turning position, the included angle between the connecting rod A 42 and the connecting rod B 43 changes due to the geometric structure, thereby changing the inclination angle of the clamp unit 3, but it will not affect the installation stability of the clamp unit 3.

[0075] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, the scope of the present application being defined by the claims appended hereto rather than by the above description, and all the changes which fall within the meaning and the scope of the equivalent elements of the claims are intended to be embraced therein.
