Description

Technical Field

[0001] The invention relates to the technical field of general cleaning equipment for packaging bottles, and in particular to a general bottle type assembly line flushing equipment capable of thoroughly cleaning. Background Art

[0002] For companies that produce liquid products, most of them need to use packaging bottles to fill liquid products. The demand for packaging bottles is increasing, and most packaging bottles are recyclable glass bottles. In order to save resources and reduce costs, the empty glass bottles must be recycled and processed, and then filled with liquid products for sale. At present, many companies manually clean and disinfect the recycled dirty bottles, or cooperate with special bottle washing plants to clean and disinfect the recycled bottles. The former is not only inefficient, but also consumes too much human resources; the latter will make it difficult to return the bottles on time due to various uncertain factors, thus affecting the production progress.

[0003] There are also automatic bottle washing machines in the prior art. Before washing, the bottle mouth faces upward and enters the feeding conveyor. Then, the bottle is turned over by the bottle body turning device, so that the bottle mouth faces downward and the nozzle faces upward. The nozzle is inserted into the bottle body to spray the inside of the bottle. This washing method is not easy to leave liquid in the bottle body and is widely used. However, this washing method is easy to leave liquid in the bottle body for bottles with small bodies, especially bottles with slender mouths. The liquid used to wash the bottle is subject to downward gravity, upward surface tension and attraction between solid and liquid molecules. These three forces will reach a balanced state when the liquid reaches a certain volume, so that the liquid remains stationary in the bottle and cannot flow out completely, resulting in incomplete washing. In addition, the existing automatic bottle washing machine has relatively simple requirements for bottle types. Since its turning device can only complete clamping and turning for fixed bottle types, the clamp of the turning device fails due to mismatch for special-shaped bottles, resulting in a high failure rate, which seriously affects the washing efficiency. In addition, it can only wash fixed bottle types, resulting in low versatility and low efficiency. Summary of the invention

DETAILED DESCRIPTION

[0036] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention are described only by way of illustration. Needless to say, those of ordinary skill in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0037] like Figures 1 to 4As shown in the figure, a general bottle type assembly line washing device for thorough cleaning comprises a frame 1, a waterproof bottom plate 11 is fixedly mounted on the frame 1, a drainage device is arranged on the waterproof bottom plate 11 for discharging waste water, a bottle conveying track 2 is fixedly mounted on the waterproof bottom plate 11, a bottle conveying chain 3 is carried on the bottle conveying track 2, the bottle conveying chain 3 is connected end to end, and a plurality of pairs of bottle brackets 4 arranged at even intervals are fixedly mounted on the bottle conveying chain 3, the bottle brackets 4 are used to support bottles with the bottle mouth facing downwards, and the waterproof A rotary water washing device 5 and a rotary air washing device 6 with the same structure and synchronous transmission are sequentially installed on the bottom plate 11 along the conveying direction of the bottle conveying chain 3. The rotary water washing device 5 is connected to a water source, and the rotary air washing device 6 is connected to an air source. A drainage device is installed at the bottom of the frame 1. The bottle conveying chain 3 is located at the front end of the rotary water washing device 5 and is provided with a loading section 21. The bottle conveying chain 3 is located at the rear end of the rotary air washing device 6 and is provided with a unloading section 22. The bottle mouths of the bottles to be cleaned are loaded from the loading section 21 with the bottle mouths facing downwards, as shown in FIG. Figure 3 As shown, section A is the loading section 21, section B is the unloading section 22, and the cleaning is cyclically carried out from A to B. The bottles are sequentially placed in the bottle holder 4 from section A, and are firstly washed with water by the rotary water washing device 5 under the conveyance of the bottle conveyor chain 3, and then blown dry by the rotary air washing device 6, and finally the cleaned bottles are unloaded from the unloading section 22. The rotary water washing device 5 and the rotary air washing device 6 are both equipped with driving devices, which provide power for the transmission of the entire bottle conveyor chain 3; when loading, the bottles are cleaned. The washed bottles are placed upside down in the bottle holder 4 without turning over. When the bottle conveyor chain 3 conveys the upside down bottles to the rotating water washing device 5 and the rotating air washing device 6, the rotating water washing device 5 and the rotating air washing device 6 extend into the bottle mouth from the bottom to spray the inside of the bottle. The rotating water washing device 5 uses pure water to wash the bottle body, and the rotating air washing device 6 uses pure air to wash the bottle body, and the water remaining at the bottle mouth is completely blown out. Even bottles with slender mouths have no liquid residue and are thoroughly cleaned. In addition, since the bottle holder 4 has no requirements for the bottle shape, it only needs to insert the bottleneck, which is widely applicable to the cleaning of various special-shaped bottles, reducing the failure rate, improving the cleaning efficiency, and having strong versatility.

[0038] like Figures 5 to 11As shown in common, the rotary washing device 5 includes a bearing seat 51 fixedly mounted on the waterproof bottom plate 11, a rotating shaft 52 is rotatably mounted in the bearing seat 51, a driving gear plate 53 is provided below the bottom of the rotating shaft 52 extending out of the waterproof bottom plate 11, and the driving gear plate 53 is connected to the driving device; the top of the rotating shaft 52 extends out of the top of the bearing seat 51 and a sprocket turntable 54 is fixedly mounted, the sprocket turntable 54 is used to drive the bottle conveying chain 3, and a plurality of through holes are evenly distributed around the sprocket turntable 54. A support tube 55 is fixedly installed in each through hole, a double-ear plate 5511 is fixedly installed on the top of the support tube 55, a ring hose rack 56 is fixedly installed on the top of the double-ear plate 5511, a nozzle lifting device 57 is slidably installed in the support tube 55, a tension spring 5713 is connected between the top of the nozzle lifting device 57 and the double-ear plate 5511, and an arc-shaped lifting guide rail 58 is fixedly installed around the rotating shaft 52 on the waterproof bottom plate 11, and the arc-shaped lifting guide rail 58 is fixedly installed on the waterproof bottom plate 11 through a plurality of pillars. The bottom end of the nozzle lifting device 57 is always close to the arc-shaped lifting guide rail 58 and moves with the rotation of the sprocket turntable 54. The driving device can be a motor, which drives the driving gear plate 53 at the bottom of the waterproof bottom plate 11 to rotate, thereby driving the sprocket turntable 54 to rotate. The outer periphery of the sprocket turntable 54 is evenly distributed with a plurality of arc-shaped notches, and the spacing between the arc-shaped notches is equal to the spacing between the hinge shafts 31 of the bottle conveying chain 3, so the arc-shaped notches and the hinge shafts 31 can correspond one by one to complete the transmission of the bottle conveying chain 3. Since the nozzle lifting device 57 is installed in the support tube 55, and the support tube 55 is fixedly installed in the through hole on the sprocket turntable 54, the nozzle lifting device 57 is driven to rotate synchronously when the sprocket turntable 54 rotates, realizing the synchronous displacement of the nozzle lifting device 57 and the bottle bracket 4, so that the nozzle 575 is accurately inserted into the bottle to achieve the limit in the vertical direction. Since the nozzle lifting device 57 is fixed to the double ear plate 5511 by the tension spring 5713, the nozzle lifting device 57 always has the potential energy to move upward under the tension of the tension spring 5713. The setting of the arc-shaped lifting guide rail 58 limits the upward movement trajectory of the nozzle lifting device 57, ensuring that there is no interference between the nozzle lifting device 57 and the bottle conveying chain 3. Only when the nozzle lifting device 57 moves to the highest point of the arc-shaped lifting guide rail 58 can it be inserted into the bottle body to rinse the bottle body. When the nozzle lifting device 57 has not yet moved to the highest point of the arc-shaped lifting guide rail 58, the nozzle lifting device 57 can just avoid the bottle conveying chain 3, thereby ensuring the stability of operation. Figures 5 to 10 In order to express the other structures more clearly, the tension spring 5713 is not drawn. Fig.11 The installation position of the tension spring 5713 is illustrated in the figure. The annular hose rack 56 is used to support and fix the hose 577 for conveying pure water and air.

[0039] like Figures 5 to 11As shown together, the sprocket turntable 54 includes a circular turntable 541 fixedly connected to the top of the rotating shaft 52, and an annular sprocket disk 542 is fixedly installed on the top of the circular turntable 541. The through holes are evenly arranged at the overlap of the circular turntable 541 and the annular sprocket disk 542. The through holes include a circle of large through holes 5421 and a circle of small through holes 5422. The circular turntable 541 and the annular sprocket disk 542 are both provided with a plurality of drainage holes for draining water when spraying the outside of the bottle body. The support tube 55 includes a fixedly installed large through hole 5421. The tension spring support tube 551 in 421 has a guide tube 552 fixedly mounted inside the tension spring support tube 551. The tension spring support tube 551 extends upward, and the guide tube 552 extends downward. The tube wall of the tension spring support tube 551 is provided with upper long slot holes 5512 arranged opposite to each other. The upper long slot holes 5512 are used to avoid the up and down movement of the tension spring shaft 5711. The tube wall of the guide tube 552 is provided with lower long slot holes 5521 arranged opposite to each other. The lower long slot holes 5521 are used to avoid the up and down movement of the connecting rod 5712. The nozzle lifting device 57 includes a lifting shaft 571 slidably installed in the tension spring support tube 551 and the guide tube 552, and a tension spring shaft 5711 arranged opposite to each other is fixedly installed on the top of the lifting shaft 571. The two tension spring shafts 5711 respectively extend their corresponding upper long slot holes 5512, and the tension spring shafts 5711 are connected to the double ear plate 5511 through tension springs 5713. A connecting rod 5712 is fixedly installed on the bottom of the lifting shaft 571, and one of the lower long slot holes 5521 extending from one end of the connecting rod 5712 is installed with a roller 572, and another lower long slot hole 5521 extending from the other end of the connecting rod 5712 is fixedly installed with a nozzle fixing rod 573, a nozzle device is installed on the nozzle fixing rod 573, and a nozzle guide device is also installed on the nozzle fixing rod 573. The nozzle guide device is used to further limit the axial displacement and shaking of the nozzle device to ensure the stability of the work. The roller 572 is used in conjunction with the arc-shaped lifting guide rail 58. The roller 572 always clings to the arc-shaped lifting guide rail 58 from below. A wear-resistant guide sleeve 5714 is fixedly installed at the bottom of the lifting shaft 571 and is used in sliding cooperation with the inner wall of the guide cylinder 552. The wear-resistant guide sleeve 5714 is preferably made of polytetrafluoroethylene, which is not only resistant to high temperature and corrosion but also has good wear resistance, which effectively ensures that the lifting shaft 571 does not deviate when it moves up and down in the guide cylinder 552, and greatly extends its service life.

[0040] like Figures 5 to 11As shown together, the nozzle device includes a water inlet pipe fixing plate 5731 fixedly mounted on the nozzle fixing rod 573, the water inlet pipe fixing plate 5731 is vertically mounted to the nozzle fixing rod 573, a vertically arranged water inlet pipe 574 is fixedly mounted on the water inlet pipe fixing plate 5731, the top of the water inlet pipe 574 is slidably mounted in the small through hole 5422, two nozzles 575 are fixedly mounted in parallel and at intervals on the nozzle fixing rod 573, the two nozzles 575 extend upward, and the bottom of the nozzles 575 are commonly connected to a water diverter valve 576, which is connected to the bottom of the water inlet pipe 574 through a hose 577. The top of the water inlet pipe 574 is connected to a water source or an air source through a hose 577, and the hose 577 at the top of the water inlet pipe 574 is supported and fixed by a ring hose rack 56. The water diverter valve 576 can control the flow rate of water spraying and the flow rate of jetting. Since each pair of bottle holders 4 can hold two bottles at the same time, the two spray pipes 575 can be inserted into the two bottles at the same time for cleaning, thereby improving the cleaning efficiency.

[0041] like Figures 5 to 11 As shown together, the nozzle guide device includes a guide limit hole 5732 provided on the nozzle fixing rod 573, and a guide flat steel 578 is slidably installed in the guide limit hole 5732. The guide flat steel 578 is parallel to the guide cylinder 552, and the bottom end of the guide flat steel 578 is fixedly connected to the bottom end of the guide cylinder 552, and the top end of the guide flat steel 578 is fixedly connected to the top end of the guide cylinder 552. The guide flat steel 578 is used to axially limit the nozzle device to ensure the accuracy of its displacement and better align it with the bottle bracket 4.

[0042] like Figures 12 to 18 As shown in the figure, the bottle conveying chain 3 includes a plurality of vertically arranged hinge shafts 31, an upper chain plate 32 is hinged between the upper ends of two adjacent hinge shafts 31, and a lower chain plate 33 is hinged between the lower ends of two adjacent hinge shafts 31; the upper chain plate 32 and the lower chain plate 33 are both made of 304 stainless steel, which greatly improves the service life compared with the nylon or polyoxymethylene materials in the prior art. The bottle bracket 4 includes a bracket base 41, the middle part of the bracket base 41 vertically penetrates the upper chain plate 32, and the bracket base 41 is The two ends are rotatably mounted with bracket rollers 42, which are used in conjunction with the bottle conveying track 2. The two ends of the upper surface of the bracket base 41 are penetrated by vertical circular holes 411, and a plurality of triangular support plates 412 are evenly spaced at intervals at the lower end of the vertical circular holes 411. The triangular support plates 412 together surround and form a guide seat inner cavity, and a nozzle guide seat 43 is fixedly mounted in the guide seat inner cavity. The nozzle guide seat 43 is used to guide and position the nozzle 575 extending from below so that it faces the center of the bottle body. A hollow outer bottle holder 44 is detachably mounted above the nozzle guide seat 43 in the vertical circular hole 411, and the outer bottle holder 44 is used to support the bottleneck. Fig.18As shown, the nozzle guide seat 43 is a hollow structure, and a bell mouth 431 is provided at the bottom of the nozzle guide seat 43. The setting of the bell mouth 431 provides a guiding and positioning function for the insertion of the nozzle 575. A plurality of water outlets 432 are provided on the side wall of the nozzle guide seat 43. After the nozzle 575 is inserted into the bottle body, the flushing water flows into the nozzle guide seat 43 and flows out from the water outlets 432 of the nozzle guide seat 43.

[0043] The outer bottle holder 44 can be in various structural forms, such as Figure 12 to Figure 14 , Fig.15 As shown in the figures, the outer bottle holder 44 includes a connecting portion 441 for inserting into the vertical circular hole 411, a bottleneck accommodating hole 4411 is provided at the axis of the connecting portion 441, a bottle body guide portion 442 is integrally provided at the upper end of the connecting portion 441, a bottle body avoidance notch 4421 is provided on the bottle body guide portion 442, and a transition slope 443 is provided between the bottle body guide portion 442 and the bottleneck accommodating hole 4411. The bottleneck accommodating hole 4411 is used to limit the bottleneck, and the bottle body guide portion 442 is used to limit the bottle body. When the size of the bottleneck is much smaller than the bottleneck accommodating hole 4411, or the bottleneck is too short to extend deep enough into the bottleneck accommodating hole 4411, a corresponding annular bushing can be added to enhance the stability of the bottle body. The bushing can be of various sizes and can be directly placed in the bottleneck accommodating hole 4411 to play the role of raising the bottleneck or enhancing the adaptation of the bottleneck to the bottleneck accommodating hole 4411. The bottle body avoidance notch 4421 is used for achieving better compatibility with the bottle body of a special-shaped bottle.

[0044] The outer bottle holder 44 can also be of the following structure: Figure 12 to Figure 14 , Fig.16 As shown in the figure, the outer bottle holder 44 includes a transition sleeve 444 for inserting into the vertical circular hole 411, a guide sleeve 446 is installed in the transition sleeve 444 through a return spring 445, and the guide sleeve 446 is used to limit the bottleneck. A guide bottle liner 447 is installed outside the transition sleeve 444, and the upper part of the guide bottle liner 447 is in a trumpet shape, and a drainage port 4471 is opened on the outer wall of the guide bottle liner 447. When the body of the special-shaped bottle is too large, the following method can also be used: Fig.16 In the structural form of the outer bottle holder 44 shown, the guide sleeve 446 is used to limit the bottleneck. Since the guide sleeve 446 is installed in the transition sleeve 444 through the return spring 445, the guide sleeve 446 can freely extend and retract to a stable state according to the length of the bottleneck and the gravity of the bottle body, thereby ensuring the accuracy of its axis. The shape of the trumpet mouth 431 of the guide bottle liner 447 can determine the size according to the bottle body of the special-shaped bottle. The outer wall of the guide bottle liner 447 is provided with a drainage port 4471 for drainage when the bottle body is sprayed externally.

[0045] Since the outer bottle holder 44 is inserted into the vertical circular hole 411, its installation method is very flexible and can be appropriately selected and matched according to the shapes of a batch of bottle products. The structure of the outer bottle holder 44 is not limited to the structure provided in this embodiment.

[0046] like Figures 2 to 3 As shown together, a circulating water pre-washing device 7 and a clean water pre-washing device 8 are also installed on the waterproof bottom plate 11 along the conveying direction of the bottle conveying chain 3. The circulating water pre-washing device 7 is located at the front end of the clean water pre-washing device 8, and the clean water pre-washing device 8 is located at the front end of the rotary water washing device 5. A plurality of steering driven turntables 9 are also installed on the waterproof bottom plate 11 along the conveying direction of the bottle conveying chain 3. The circulating water pre-washing device 7 and the clean water pre-washing device 8 include a driven turntable, and the outer periphery of the driven turntable is provided with a notch for use with the hinge shaft 31 of the bottle conveying chain 3, so that it rotates following the movement of the bottle conveying chain 3. A plurality of circumferentially arranged water spray pipes are installed at the bottom of the driven turntable, corresponding to the bottle mouth position on the bottle bracket 4. Two circulating water pre-washing devices 7 are provided in this embodiment, and one clean water pre-washing device 8 is provided in this embodiment. The number can be selected according to actual needs and space layout. A circulating water tank is provided in the frame 1. The invention continuously filters and stores the circulating water after flushing the bottle body. The circulating water pre-washing device 7 uses the circulating water in the circulating water tank, which is a pre-washing function, which moistens the dirt inside the bottle body and preliminarily cleans the bottle body. The clean water pre-washing device 8 is arranged behind the circulating water pre-washing device 7, and uses relatively clean tap water or purified water, which is determined according to the specific cleaning requirements of the bottle body. The nozzles of the water spray pipes of the circulating water pre-washing device 7 and the clean water pre-washing device 8 do not extend into the bottle body, and the water flow is pressurized to spray into the bottle body for pre-washing. The steering driven turntable 9 is also a driven turntable, which is selected according to the layout of the machine body and the direction requirements of the conveying, and is used for the steering of the bottle conveying track 2.

[0047] The frame 1 includes a loading and unloading section 22 and a cleaning section, and end plates 12 are fixedly installed at both ends of the cleaning section, and two parallel beams 13 are fixedly installed between the tops of the two end plates 12, and side plates 14 are hinged on the beams 13 to the two sides of the frame 1, and a plurality of top plates 15 are detachably installed between the two beams 13, and observation windows 141 are provided on the side plates 14. The side plates 14 can be opened upwards, and the top plates 15 can be completely removed, which is convenient for the maintenance and repair of the machine, and the observation window 141 can observe the situation inside the machine body in real time.

[0048] The present invention has the following advantages:

[0049] When loading, the bottle to be cleaned is placed upside down in the bottle holder 4 without turning it over. The rotating water washing device 5 and the rotating air washing device 6 are sequentially extended from the bottom into the bottle mouth to spray the inside of the bottle. The rotating water washing device 5 uses pure water to wash the bottle body, and the rotating air washing device 6 uses pure air to wash the bottle body, and the water remaining at the bottle mouth is completely blown out. Even the bottle with a slender mouth has no liquid residue and is thoroughly cleaned. Moreover, since the bottle holder 4 has no requirements for the bottle shape, it only needs to insert the bottleneck, which is widely applicable to the cleaning of various special-shaped bottles, reducing the failure rate, improving the cleaning efficiency, and having strong versatility.
