Description

Technical Field

[0002] At a time when plastic bottles are widely used in many industries with extremely high hygiene requirements, such as food, medicine, and cosmetics, it is crucial to ensure the aseptic production of plastic bottles.

[0003] Traditional plastic bottle production equipment and processes have some defects during use: on the one hand, in the transmission link, most of them use simple conveyor belts, which cannot accurately fix the position of plastic bottles, causing plastic bottles to easily move and shake during the transmission process. This will not only interfere with the accuracy of subsequent processes such as filling and labeling, but also once the bottle collides with the internal parts of the equipment, it may also produce plastic debris and other pollutants, seriously threatening the aseptic production environment. At the same time, traditional conveying devices lack adaptability considerations for different bottle types. When switching products, it often requires a lot of effort or replacement of conveying parts, which greatly reduces production efficiency.

[0004] On the other hand, when the dust-free workshop where the plastic bottle aseptic production equipment is located cannot maintain a dust-free state, pollutants such as microorganisms and dust in the air will enter the plastic bottles, causing bacteria, mold and other microorganisms to grow in the bottles, contaminating the products, affecting the sterility of the products, and reducing product quality. For products such as food and medicines that have extremely high hygiene requirements, it may cause food safety or drug safety problems, or cause the factory production to be suspended, reducing the production efficiency of the workshop.

[0038] Example

[0039] See also Figures 1 to 3 The present invention provides a technical solution: a plastic bottle aseptic production equipment and process, comprising a mounting frame 1, legs 2 are arranged at the four corners of the bottom of the mounting frame 1, a conveying limit mechanism 3 is arranged on the inner wall of the mounting frame 1, a cooling and filtering mechanism 4 is arranged at the middle position of the upper part of the mounting frame 1, and a negative pressure mechanism 5 is arranged at the middle position of the lower part of the mounting frame 1;

[0040] The conveying limit mechanism 3 includes a servo motor 301, a conveyor belt 303, a tooth hole 304, a storage sleeve 305, a fixing rod 307, a connecting sleeve shaft 308, a positioning rod 309 and a gear 306. The inner wall of the mounting frame 1 is provided with a conveyor belt 303, and the outer wall of the mounting frame 1 is provided with a servo motor 301. The output shaft of the servo motor 301 passes through the mounting frame 1 and is connected to the driving roller of the conveyor belt 303. Two rows of fixing rods 307 are symmetrically fixed on the conveyor belt 303, and the top of the fixing rod 307 can rotate. The movable sleeve is connected to a connecting sleeve shaft 308, on which a plurality of positioning rods 309 are fixedly arranged, and a storage sleeve 305 is fixedly connected to the positioning rods 309, and a plurality of gears 306 are fixedly arranged on the outer side surface of the lower end of the storage sleeve 305, and a plurality of tooth holes 304 that can mesh with the gears 306 are provided on both sides of the inner wall of the mounting frame 1; the storage sleeve 305 is cylindrical and hollow inside, and two windows 310 are symmetrically provided on the storage sleeve 305; a plurality of through holes 302 are provided on the surface of the conveyor belt 303;

[0041] The conveyor belt 303 is driven by the servo motor 301, and the conveying speed and direction of the plastic bottles can be controlled. The fixed rod 307, the connecting sleeve shaft 308, the positioning rod 309 and the storage cover 305 on the surface of the conveyor belt 303 constitute a stable placement structure, so that the plastic bottles can be accurately placed and move with the conveyor belt 303. The storage cover 305 is cylindrical and hollowed out inside, and has two windows 310. This design can adapt to plastic bottles of different shapes and sizes. The cylindrical shape can fit the bottle body, and the design of the hollow and the window 310 is convenient for processing the bottle body or observing the state of the bottle body, and also reduces the weight of the storage cover 305. The through holes 302 on the surface of the conveyor belt 303 are conducive to air circulation. During the conveying process, it can cooperate with other mechanisms to perform cooling or drying operations, and can also reduce the air pressure difference between the upper and lower surfaces of the conveyor belt 303, so that the conveyor belt 303 runs more smoothly. The gear 306 on the outer side of the lower end of the storage cover 305 is meshed with the tooth holes 304 on both sides of the inner wall of the mounting frame 1. During the movement of the conveyor belt 303, this meshing structure can limit the rotation and horizontal displacement of the storage cover 305, thereby ensuring that the plastic bottles maintain a stable posture during the conveying process, avoiding shaking or deviation from affecting the subsequent processing technology, such as avoiding incomplete processing of plastic bottles due to inaccurate position during aseptic processing.

[0042] like Figure 4 , Figure 5As shown, the cooling and filtering mechanism 4 includes a frame 401, a baffle 402, a fixing bolt 403, a cooling fan 404, an air outlet pipe 409, a nozzle 410, a filter box 405, a sealing plate 406, a hose 408 and an air inlet pipe 407. The frame 401 is fixedly provided in the middle of the mounting frame 1, and the baffle 402 is movably connected to the left and right sides of the frame 401. The fixing bolt 403 is penetrated on the opposite side of the baffle 402. The top of the frame 401 is fixedly connected to the cooling fan 404, the air outlet end of the cooling fan 404 is connected to the air outlet pipe 409, and the bottom of the air outlet pipe 409 is connected to the nozzle 410. , a filter box 405 is fixedly connected to the rear side of the frame 401, a sealing plate 406 is fixedly connected to the top of the filter box 405 by bolts, a hose 408 is connected to the air inlet end of the cooling fan 404, the bottom of the hose 408 penetrates to the bottom of the sealing plate 406 and extends into the filter box 405; a non-woven filter element 412 and an activated carbon filter element 413 are fixedly installed in the inner cavity of the filter box 405, and an air inlet pipe 407 is connected to the rear side of the filter box 405; the opposite end of the fixing bolt 403 penetrates to the inner cavity of the frame 401, and a mounting hole is opened on the baffle 402; the number of nozzles 410 is several;

[0043] It should be noted that the cooling fan 404 blows air to the passing plastic bottles through the air outlet pipe 409 and multiple nozzles 410, which can quickly take away the heat of the plastic bottles and achieve efficient cooling. The baffles 402 on both sides of the frame 401 can adjust the size of the internal space of the frame 401, and are fixed by fixing bolts 403. The cooling area can be flexibly adjusted according to the size and number of the plastic bottles to achieve better cooling effect. The filter box 405 contains a non-woven filter element 412 and an activated carbon filter element 413, which can filter the air entering the cooling fan 404, remove dust, impurities and odors, and ensure that the air blown to the plastic bottles is clean and sterile. The fixing bolts 403 penetrate the mounting holes on the frame 401 and the baffle 402, ensuring the firmness of the baffle 402 after adjusting the position, and avoiding the baffle 402 from loosening during the operation of the equipment to affect the cooling effect. Multiple nozzles 410 can evenly distribute the cooling air around the plastic bottles, ensuring that each plastic bottle can be fully cooled, and improving the cooling efficiency and quality.

[0044] like Figure 6 and Figure 7As shown, the negative pressure mechanism 5 includes a collecting bucket 503, a fixing frame 501, a heat dissipation fan 502, a chute 504, a handle 506 and a net frame 505. The bottom of the conveyor belt 303 is fixedly connected with the collecting bucket 503, the inner cavity of the collecting bucket 503 is provided with a chute 504, the inner cavity of the collecting bucket 503 is slidably connected with the net frame 505, the outer wall of the net frame 505 is fixedly connected with the handle 506, the net frame 505 and the chute 504 are plugged and arranged, the left side of the bottom of the collecting bucket 503 is fixedly connected with the fixing frame 501, the top of the fixing frame 501 is fixedly connected with the heat dissipation fan 502, and the air inlet end of the heat dissipation fan 502 passes through the inner cavity of the collecting bucket 503 through a pipeline;

[0045] It should be noted that the collecting hopper 503 is located below the conveyor belt 303 and can collect impurities such as plastic debris, dust, etc. generated during the conveying and processing of plastic bottles. The net frame 505 in the collecting hopper 503 can be taken out by sliding along the slide 504 through the handle 506, which is convenient for cleaning the collected impurities. The air inlet end of the heat dissipation fan 502 passes through the inner cavity of the collecting hopper 503 through a pipeline, and can discharge the hot air in the collecting hopper 503. On the one hand, it can prevent the hot air from accumulating inside the equipment and causing the temperature to be too high, affecting the equipment performance and the quality of plastic bottles; on the other hand, the operation of the heat dissipation fan 502 helps to maintain the air pressure balance inside the equipment, making the air flow of the entire production equipment smoother, and further improving the stability and production efficiency of the equipment. At the same time, the function of collecting impurities can prevent impurities from accumulating inside the equipment, prevent impurities from contaminating plastic bottles again or entering the key components of the equipment, and extend the service life of the equipment.

[0046] The working principle of the above embodiment is as follows: the plastic bottles to be processed are placed in the storage sleeve 305. Since the storage sleeve 305 is cylindrical and hollow inside, and two windows 310 are symmetrically provided, it can accommodate plastic bottles of different shapes and sizes, and is convenient for loading. The servo motor 301 is started, and the output shaft of the servo motor 301 drives the active roller of the conveyor belt 303 to rotate, thereby driving the conveyor belt 303 to run. The two rows of fixed rods 307 symmetrically fixed on the conveyor belt 303 move together with the conveyor belt, and the connecting sleeve shaft 308 at the top of the fixed rod 307 can rotate, and the positioning rod 309 on the connecting sleeve shaft 308 is fixedly connected to the storage sleeve 305, and the gear 306 on the outer side surface of the lower end of the storage sleeve 305 is meshed with the tooth holes 304 on both sides of the inner wall of the mounting frame 1. This structure enables the storage cover 305 to not only move with the conveyor belt 303 during its operation, but also maintain a stable position and posture under the cooperation of the gear 306 and the tooth hole 304, thereby preventing the plastic bottles from shaking or deflecting during the conveying process, and achieving accurate conveying. At the same time, the plurality of through holes 302 on the surface of the conveyor belt 303 facilitates air circulation, which has a positive impact on the subsequent processes;

[0047] When the storage bag 305 with plastic bottles is moved to the position of the cooling filter mechanism 4 in the middle of the mounting frame 1 along with the conveyor belt 303, the baffles 402 on the left and right sides of the frame 401 are adjusted according to the size and number of the plastic bottles. The baffle 402 is fixed by the fixing bolt 403, and the opposite end of the fixing bolt 403 penetrates into the inner cavity of the frame 401 and cooperates with the mounting hole on the baffle 402 to ensure that the baffle 402 is firmly positioned. The outside air enters the filter box 405 through the air inlet pipe 407. The non-woven filter element 412 and the activated carbon filter element 413 fixedly installed in the inner cavity of the filter box 405 filter the air to remove dust, impurities and odors. The filtered clean air enters the cooling fan 404 through the hose 408. The cooling fan 404 sends the filtered air to multiple nozzles 410 through the air outlet pipe 409. The multiple nozzles 410 blow the air evenly to the plastic bottles, quickly taking away the heat of the plastic bottles, and achieving efficient cooling;

[0048] During the conveying and cooling process of the plastic bottles, the plastic debris, dust and other impurities generated will fall into the collecting bucket 503 below the conveyor belt 303. The inner cavity of the collecting bucket 503 is provided with a slide groove 504, and the net frame 505 is slidably connected to the collecting bucket 503 through the slide groove 504. The handle 506 on the outer wall of the net frame 505 is convenient for the operator to regularly pull out the net frame 505 and clean the collected impurities. The heat dissipation fan 502 on the left side fixed frame 501 at the bottom of the collecting bucket 503, its air inlet end passes through the inner cavity of the collecting bucket 503 through a pipeline. When the heat dissipation fan 502 is running, the hot air in the collecting bucket 503 is discharged to prevent the hot air from accumulating inside the equipment and causing excessive temperature, affecting the equipment performance and the quality of the plastic bottles. At the same time, the air pressure balance inside the equipment is maintained to make the air flow smoother;

[0049] The entire process starts with the plastic bottle being placed in the storage sleeve 305 of the conveying limit mechanism 3, and the conveyor belt 303 passes through the cooling and air filtering mechanism 4 in turn for cooling and air filtering, and the impurity collection and heat dissipation are completed under the negative pressure mechanism 5, and finally the entire aseptic production process is completed to obtain a plastic bottle that meets the aseptic requirements.

[0050] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.
