Description

Technical Field

[0001] The invention relates to the field of material packaging auxiliary equipment, in particular to an air drying system for condiment packaging containers. Background Art

[0002] Hot pot base has become the most common condiment in the current market due to its unique aroma and taste, as well as its convenience in use. Currently famous hot pots include the spicy hot pot in Sichuan and Chongqing, which is famous for its spicy and mellow flavor; the seafood hot pot in Guangdong, which is not greasy and has endless delicious taste; and the mutton hot pot in Beijing, which has a unique flavor and whets the appetite.

[0003] Pre-made hot pot base, processed by seasoning processing plants, has become the mainstream production method for hot pot base. However, the packaging of this pre-made hot pot base determines the shelf life of the hot pot base. Currently, hot pot base is mostly packaged in bags after solidification and forming into blocks. While packaging hot pot base in bags is suitable for most occasions, existing bagged hot pot bases are mostly large blocks, which are convenient for large groups of people and are suitable for hot pot restaurants or large gatherings. However, small blocks are more suitable for home use. Therefore, small blocks have a better market prospect.

[0004] For the packaging of small pieces of hot pot base, they need to be formed through packaging molds and then packaged in packaging bags or directly in packaging boxes (because packaging in packaging bags is not conducive to molding and is easy to solidify into flakes). The packaging container (i.e., packaging mold or packaging box) needs to be cleaned and disinfected before packaging, and the packaging container needs to be air-dried and sterilized with ultraviolet rays after cleaning. During the air-drying process, the open end of the packaging container is usually buckled on a mesh belt conveyor for transportation, and then a fan is set under the mesh belt conveyor for air-drying. In this way, the cleaned packaging container can be quickly air-dried, which is convenient for subsequent sterilization and packaging use. However, since the existing mesh belt conveyor is large in width and the packaging container is small, when placing the packaging container, it is necessary to manually stack the packaging container and then place it on the mesh belt conveyor for transportation and air-drying, which is more troublesome. In addition, manual stacking of packaging containers cannot guarantee the uniformity and consistency of stacking, and may cause the open end of the packaging container to face upwards when stacking, affecting the quality of air-drying and being unfavorable for the subsequent collection of the packaging container. Summary of the Invention

[0005] Therefore, in order to solve the above-mentioned shortcomings, the present invention provides a drying system for seasoning packaging containers. The drying system is provided with a conveying mechanism and an air shower mechanism at the lower end of the conveying mechanism, and the conveying surface of the conveying mechanism is kept ventilated, so as to facilitate air showering of the packaging containers conveyed on the conveying mechanism, and facilitate air drying of the packaging containers. In addition, through the automatic stacking mechanism provided above the feed end of the conveying mechanism, the packaging containers can be automatically stacked according to the width of the conveying mechanism, and then the open ends of the stacked packaging containers are snapped onto the conveying surface of the conveying mechanism, thereby facilitating the discharge of internal water stains and improving the efficiency and quality of air drying.

[0006] The present invention is achieved by constructing an air-drying system for condiment packaging containers, comprising a conveying mechanism horizontally supported by a bracket;

[0007] An automatic stacking mechanism, arranged above the feed end of the conveying mechanism, is used to evenly stack the packaging containers on the conveying mechanism for conveying;

[0008] An air shower mechanism is provided at the bottom of the conveying mechanism and inputs positive pressure air to the conveying surface of the conveying mechanism;

[0009] The conveying surface of the conveying mechanism is kept ventilated, and the automatic stacking mechanism fastens the open end of the packaging container onto the conveying surface of the conveying mechanism.

[0010] Specifically, the conveying mechanism includes a conveyor belt and frames on both sides of the conveyor belt. A rotatably mounted tensioning roller is provided between the two ends of the frames on both sides. The frames on both sides are connected together by two tensioning rollers. The conveyor belt is sleeved between the two tensioning rollers and the transmission of the conveyor belt is achieved by the rotation of the tensioning rollers. A transmission box is provided in the bracket, and a first drive motor and a transmission mechanism for driving any one of the tensioning rollers to rotate are installed in the transmission box.

[0011] Specifically, the conveyor belt is a chain mesh belt conveyor belt or a chain plate conveyor belt.

[0012] Specifically, the automatic stacking mechanism includes two support plates, which are installed oppositely on the frame on both sides of the conveyor belt;

[0013] A rotating member, rotatably arranged between the two supporting plates;

[0014] A movable splint, movably mounted on the rotating member and combined with the rotating member to support and linearly slide the packaging container;

[0015] A conveying assembly, provided on a frame outside any one of the support plates, for conveying individual packaging containers to the rotating member and the movable clamping plate;

[0016] The driving assembly is arranged on the outside of the other supporting plate and is used to drive the rotating member to rotate.

[0017] Specifically, the automatic stacking mechanism also includes a height-limiting rope, which is arranged above the rotating part and fixed to the conveying assembly and the support plate. The height-limiting rope is used to automatically remove packaging containers in an incorrectly placed state, thereby achieving uniform and unified stacking of packaging containers.

[0018] Specifically, the conveying assembly includes a fixed plate and a movable plate, the fixed plate is fixed to a frame on the outside of the conveyor belt, the movable plate is movably mounted on the outer side of the fixed plate to keep the height of the fixed plate adjustable, the ends of the fixed plate and the movable plate are close to the ends of the rotating member and the movable splint and keep the same height, one end of the height limiting rope is fixed on the outer side of the movable plate, and the other end of the height limiting rope passes over the rotating member and is fixed on the support plate. When the rotating member rotates until the movable splint and the end of the movable plate are engaged with each other, the conveying assembly conveys the packaging container to the rotating member and the movable splint. When the movable splint is separated from the movable plate, the outer end of the rotating member blocks the packaging container on the conveying assembly to stop conveying.

[0019] Specifically, a water collecting trough plate is provided at the bottom of the conveying mechanism. The bottom of the water collecting trough plate is an inclined surface and a drainage pipe is provided at the lowest point. One end of the air shower mechanism is provided in the water collecting trough plate, and the other end extends to the outside of the water collecting trough plate and is connected to an external air source.

[0020] Specifically, the air shower mechanism includes an air inlet pipe, which is vertically arranged and keeps the bottom end connected to the external air source, and the top end passes through the water collecting trough plate and keeps it sealed;

[0021] Two air supply pipes are respectively arranged on both sides of the top of the air inlet pipe along the conveying direction of the conveying mechanism and are connected thereto, and the other ends of the air supply pipes are kept sealed;

[0022] Several exhaust pipes are perpendicular to the conveying direction of the conveying mechanism and are evenly arranged above the two air supply pipes. The two ends of the exhaust pipes are sealed and the middle of the bottom end is kept connected with the air supply pipe. Several exhaust holes are evenly opened on the top.

[0023] Specifically, a pressing and conveying mechanism is provided on the frames on both sides of the conveyor belt. The four corners of the pressing and conveying mechanism are installed on the frames through height adjustment plates to keep the height adjustable. A closed soft curtain is provided between the frames and the pressing and conveying mechanism.

[0024] Specifically, the pressing and conveying mechanism includes a support frame, which is arranged above the conveyor belt and has long holes on its four corners for maintaining movable installation with the height adjustment plate, and a receiving groove is provided on the opposite surface of the support frame and the conveyor belt;

[0025] A compression conveyor belt is arranged in the receiving groove of the support frame to maintain rotation and conveying, and there is a gap between the end of the compression conveyor belt and the inner wall of the receiving groove of the support frame;

[0026] The exhaust pipe has one end fixed on the outer side of the support frame and communicated with the accommodating groove, and the other end extending outward.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] 1. Improved air-drying quality and efficiency: This air-drying system utilizes an automatic stacking mechanism, a ventilated conveying mechanism, and an air shower mechanism at the bottom of the conveying mechanism to achieve automatic stacking of packaging containers and effective air drying during conveying. This design allows for flexible adjustment of the stacking pattern based on the width of the conveying mechanism, ensuring that the open ends of the packaging containers fit snugly on the conveying surface. This effectively drains water from the packaging containers, significantly improving air-drying quality and efficiency.

[0029] 2. Preventing water spillage and ensuring uniform air drying: This air drying system features a water collection trough beneath the conveyor mechanism, effectively preventing the uncontrolled escape of water and maintaining a clean and safe working environment. Furthermore, the rationally designed air shower mechanism evenly discharges positive pressure air toward the packaging containers on the conveyor mechanism, ensuring that all parts of the packaging containers are thoroughly and evenly dried, further enhancing the air drying effect.

[0030] 3. Enhanced Conveying Stability and Adaptability: This air-drying system features a press-and-conveyor mechanism above the conveyor mechanism. This design effectively prevents containers from being blown upward by airflow during the air shower process, thereby separating them from the conveyor mechanism and ensuring container stability during conveyance. Furthermore, the height adjustability of the press-and-conveyor mechanism allows the system to flexibly accommodate containers of varying heights, significantly broadening its application range and enhancing the equipment's versatility and practicality.

[0031] In summary, this air-drying system, through a series of innovative designs, not only significantly improves the quality and efficiency of air-drying, but also effectively prevents water spillage, enhances conveying stability and adaptability, and provides an efficient and reliable solution for the air-drying of packaging containers.

[0059] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings; it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention in any way; the drawings in the present invention are only used to assist in the description of the embodiments and to facilitate understanding and are not intended to limit the present invention in any way.

[0060] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the conditions under which the present invention can be implemented. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in the present invention without affecting the efficacy and purpose that can be achieved by the present invention.

[0061] As described in the background technology, the hot pot base packaging container needs to be cleaned, air-dried and sterilized before being filled with hot pot base. The existing method is to buckle the open end of the packaging container above the mesh belt conveyor for transportation, and set a fan at the bottom of the mesh belt conveyor for air drying. However, the existing mesh belt conveyor is relatively wide, and the packaging containers need to be manually stacked on the conveyor for transportation during air drying. Manually stacking the packaging containers is more troublesome, and the uniformity and consistency of the stacking cannot be guaranteed, which may cause the open end of the packaging container to face upward, affecting the quality of air drying.

[0062] Based on the above reasons, the present invention provides an air-drying system for condiment packaging containers, comprising a conveying mechanism 2, which is horizontally supported by a bracket 1;

[0063] An automatic stacking mechanism 3 is provided above the feed end of the conveying mechanism 2 and is used to evenly stack the packaging containers on the conveying mechanism 2 for conveying;

[0064] The air shower mechanism 6 is provided at the bottom of the conveying mechanism 2 and inputs positive pressure air to the conveying surface of the conveying mechanism 2;

[0065] The conveying surface of the conveying mechanism 2 is kept ventilated, and the automatic stacking mechanism 3 fastens the open end of the packaging container onto the conveying surface of the conveying mechanism 2.

[0066] Please see the attached Figure 1 and attached Figure 4 Specifically, the conveying mechanism 2 includes a conveyor belt and frames on both sides of the conveyor belt. A rotatably installed tensioning roller is provided between the two ends of the frames on both sides. The frames on both sides are connected together by two tensioning rollers. The conveyor belt is arranged between the two tensioning rollers and the transmission of the conveyor belt is realized by the rotation of the tensioning rollers. A transmission box 9 is provided in the bracket 1, and a first drive motor 10 and a transmission mechanism for driving any one of the tensioning rollers to rotate are installed in the transmission box 9.

[0067] According to the technical features described in the previous paragraph, the transmission mechanism is a conventional belt transmission mechanism (since the belt transmission structure is a conventional mechanical transmission structure and is blocked from view, it is not shown in detail in the accompanying drawings).

[0068] Specifically, the conveyor belt is a chain mesh conveyor belt or a chain plate conveyor belt (in the attached figure, the chain plates of the chain plate conveyor belt are replaced with rods. Compared with chain plates, rods are convenient for drainage and ventilation, thereby improving the drying efficiency and quality of packaging containers).

[0069] Furthermore, the specific structure and transmission form of the conveying mechanism can refer to the existing chain conveyor or mesh belt conveyor, and the specific structure and transmission principle will not be described in detail here.

[0070] Please see the attached Figure 17 and attached Figure 18 The packaging container is a packaging mold 12 or a packaging box 13. The packaging mold 12 is in the shape of a conical prism, and a receiving groove is provided at its large end. This method is convenient for putting in the hot pot base and demoulding it after solidification, which is convenient for subsequent use. The packaging box 13 is a prismatic structure, and a flange is provided on the outside of the open end. The flange is provided to facilitate the later sealing of the open end to achieve airtight packaging.

[0071] Please see the attached Figure 8 ~Attached Figure 16 Specifically, the automatic stacking mechanism 3 specifically includes two support plates 301, which are installed on the frames on both sides of the conveyor belt;

[0072] A rotating member 304 is rotatably disposed between the two support plates 301;

[0073] A movable splint 305 is movably mounted on the rotating member 304 and is combined with the rotating member 304 to support and linearly slide the packaging container;

[0074] A conveying assembly, provided on a frame outside any one of the support plates 301, is used to convey individual packaging containers to the rotating member 304 and the movable clamping plate 305;

[0075] The driving assembly is arranged on the outside of the other supporting plate 301 and is used to drive the rotating member 304 to rotate.

[0076] According to the description in the previous paragraph and the shape of the packaging mold or packaging box, the tapered end of the packaging mold can be placed (keeping the large end on top) between the rotating part and the movable splint for support and sliding, or the flange of the packaging box can be placed between the rotating part and the movable splint for support and sliding, so that after subsequent rotation, the packaging mold or packaging box will keep the open end in contact with the conveying surface of the conveying mechanism after falling under the action of gravity.

[0077] Please see the attached Figure 12 and attached Figure 13 Furthermore, a baffle 14 is provided on the inner side surface of any support plate 301 (the side surface is the surface close to the conveying mechanism), and the baffle 14 is arc-shaped and extends to the other support plate 301. When the packaging mold 12 or the packaging box 13 is placed on the rotating member 304 and rotated, the open end of the packaging mold 12 or the packaging box 13 can rotate downward along the inner end of the baffle 14 to prevent the packaging mold 12 or the packaging box 13 from falling directly during the rotation and causing random rolling of the packaging mold 12 or the packaging box 13, affecting subsequent air drying.

[0078] As described in the previous paragraph, the baffle is provided to prevent the packaging mold 12 or packaging box 13 from falling prematurely when the rotating part 304 rotates downward due to the tilt of the rotating part, thereby causing the packaging mold 12 or packaging box 13 to tilt or flip after falling, resulting in the open end facing upward and affecting air drying.

[0079] Please see the attached Figure 8 ~Attached Figure 13 Specifically, the automatic stacking mechanism 3 also includes a height limiting rope 309, which is arranged above the rotating part 304 and fixed on the conveying assembly and the support plate 301. The height limiting rope 309 automatically removes the packaging containers in the wrong placement state, so as to achieve uniform and unified stacking of the packaging containers.

[0080] As described in the previous paragraph, the purpose of setting the height limiting rope is to prevent the packaging container from being transported to the rotating part through the conveying assembly with the open end unable to face upward (the open end may face downward or tilted upward), causing the packaging container to be placed on the rotating part at an angle or with the open end facing downward. After rotation, it is impossible to ensure that the open end of the packaging container is in contact with the conveying surface of the conveying mechanism. By setting the height limiting rope, if the packaging container is placed on the rotating part with the open end facing downward or tilted upward, the packaging container with the open end facing downward can be pushed out of the rotating part or the packaging container with the open end tilted upward can be pushed to the left or right, and then fall from the gap between the rotating part and the movable splint 305.

[0081] Preferably, the height-limiting rope can be set as an elastic rope so that the length can be adaptively adjusted according to the installation position of the conveying component to avoid the installation position inside the conveying component being unable to be adjusted.

[0082] Please combine the attached Figure 14 and attached Figure 15 Furthermore, the rotating member 304 is composed of mounting plates 3041 at both ends and a connecting portion 3043 connecting the two mounting plates 3041. A connecting rod 3042 for maintaining a rotational connection with the support plate 301 is provided at the center of the outer end of the mounting plate 3041. A fixed splint 3044 is provided on one side of the top of the two mounting plates 3041, and a movable splint 305 is movably installed on the other side of the top of the two mounting plates 3041. The fixed splint 3044 and the movable splint 305 are arranged in parallel and maintain the same height.

[0083] Furthermore, the movable splint 305 is placed on the mounting plate 3041, and a connecting plate with a mounting hole is provided at the bottom of the movable splint 305 near the mounting plate 3041. A strip hole 3046 is provided on the mounting plate 3041 at a height corresponding to the mounting hole of the connecting plate. The strip hole 3046 is kept perpendicular to the fixed splint 3044, and the movable splint 305 maintains a movable connection with the rotating part 304 through the adjusting part 306 (i.e., bolt and nut) passing through the mounting hole of the connecting plate and the strip hole 3046.

[0084] According to the above two paragraphs, the provision of a fixed clamping plate on the rotating member and a movable clamping plate movably connected to the rotating member is to facilitate adjustment of the distance between the movable clamping plate and the fixed clamping plate, thereby supporting or placing packaging containers of different sizes.

[0085] Furthermore, the top of the connecting portion 3043 is an inclined surface, which is away from the conveying mechanism 2 . The purpose of this arrangement is to facilitate the discharge of packaging containers that fall from the gap between the rotating member and the movable clamping plate 305 .

[0086] Furthermore, a blocking portion 3047 is provided on the outer side surface of the mounting plate 3041 close to the conveying assembly, and a through groove is provided on the area of the blocking portion 3047 corresponding to the fixed clamping plate 3044 and the movable clamping plate 305.

[0087] As described in the previous paragraph, the purpose of providing the blocking portion is to ensure that during the rotation of the rotating member 304, if the fixed splint 3044 and the movable splint 305 correspond to the conveying assembly, the packaging container can pass through the through groove of the blocking portion 3047 and be conveyed by the conveying assembly to the fixed splint 3044 and the movable splint 305 of the rotating member 304; if the fixed splint 3044 and the movable splint 305 do not correspond to the conveying assembly, the blocking portion 3047 prevents the conveying assembly from continuing to convey the packaging container, thereby realizing automatic conveying and stopping of the packaging container.

[0088] Furthermore, a limiting rod 3045 is provided on the side of the fixed splint 3044 away from the conveying assembly. The movable splint 305 can pass through the limiting rod 3045 and move in a straight line. The limiting rod 3045 limits the conveying of the packaging container to prevent the packaging container from being unable to be positioned and thus unable to be evenly stacked.

[0089] Please combine the attached Figure 8 and attached Figure 16 The movable plate 308 is movably mounted on the outer surface of the fixed plate 307 to keep the height of the fixed plate 307 adjustable. The ends of the fixed plate 307 and the movable plate 308 are close to the ends of the rotating member 304 and the movable splint 305 and keep the same height. One end of the height limiting rope 309 is fixed on the outer surface of the movable plate 308, and the other end of the height limiting rope 309 passes over the rotating member 304 and is fixed on the support plate 301. When the rotating member 304 rotates until the movable splint 305 and the end of the movable plate 308 are engaged with each other, the conveying assembly conveys the packaging container to the rotating member 304 and the movable splint 305. When the movable splint 305 is separated from the movable plate 308, the outer end of the rotating member 304 blocks the packaging container on the conveying assembly to stop conveying.

[0090] Please refer to the attached Figure 16The bottom of the fixed plate 307 can be directly fixed (such as by welding) on the frame, and the bottom side of the movable plate 308 is provided with a guide column and a screw, which pass through the bottom side of the fixed plate 307 and are fixed by nuts, thereby realizing the adjustment of the distance between the fixed plate 307 and the movable plate 308, so as to support or place packaging containers of different sizes.

[0091] Furthermore, one end of the fixed plate 307 and the movable plate 308 corresponds to the rotating member 304 and the movable clamping plate 305, and the other end can be connected to a packaging container feeding conveyor belt. The packaging container feeding conveyor belt can adopt a conventional belt conveyor to transport packaging containers individually.

[0092] Please see the attached Figure 8 Specifically, the drive assembly includes a second drive motor 302 and a worm gear transmission mechanism 303. The worm gear of the worm gear transmission mechanism 303 is installed on a connecting rod 3042 outside any mounting plate 3041, and the worm gear is rotatably installed on the outer surface of the support plate 301 and maintains connection and transmission with the second drive motor 302.

[0093] As described in the previous paragraph, the purpose of providing the worm gear transmission mechanism is to ensure that the rotating member does not rotate naturally and can only be rotated by the second drive motor 302, thereby avoiding random rotation when stacking the packaging containers and affecting the stacking.

[0094] Furthermore, the automatic stacking mechanism also includes a control system and a sensing device. The control system is a PLC control system for controlling the start-up time of the second drive motor. At the same time, the sensing device is an infrared light sensing device arranged between the gap between the conveying component and the rotating part. When the infrared light in the gap between the conveying component and the rotating part is blocked by the packaging container within a preset time (determined according to the conveying speed of the conveying component and the size of the packaging container), a control signal is sent to the control system to control the start-up of the second drive motor. The preset time can be calculated by the following method:

[0095] T=S / V

[0096] Where T is the preset time, in seconds (s);

[0097] S is the length of the packaging container in the conveying direction, in centimeters (cm);

[0098] V is the conveying speed of the conveying component to the packaging container, in centimeters per second (cm / s).

[0099] The control mode of the control system is as follows:

[0100] 1. The conveying component conveys the packaging container to the rotating part. When the sensor device does not detect infrared light within the preset time T, it means that enough packaging containers have been stacked on the surface rotating part, and a signal is sent to the control system;

[0101] 2. The control system starts the second drive motor, driving the worm to rotate. Under the transmission action of the worm gear transmission mechanism, the rotating member rotates 180° in the conveying direction of the conveying mechanism. During the rotation, the rotating member turns the packaging container downward with the top and the movable splint. When the packaging container reaches 180°, it loses the obstruction of the baffle and falls off to the conveying mechanism under gravity for conveying and drying. At the same time, during the rotation, the blocking part blocks the packaging container on the conveying assembly, stopping the conveying of the packaging container.

[0102] 3. After a certain period of time (for example, 3 seconds), the control system controls the second drive motor to reverse. Under the transmission action of the worm gear transmission mechanism, the rotating member rotates 180 degrees in the opposite direction, so that the rotating member returns to its original position. At this time, the blocking part rotates accordingly, and its through slot is located between the rotating member and the conveying assembly, making it easy for the packaging container to pass through the through slot and move onto the rotating member for stacking again.

[0103] Repeat the above steps to realize automatic stacking and transportation of packaging containers.

[0104] Please see the attached Figure 2 or attached Figure 4 Specifically, a water collecting trough plate 7 is provided at the bottom of the conveying mechanism 2. The bottom of the water collecting trough plate 7 is a slope and a drainage pipe 8 is provided at the lowest point. One end of the air shower mechanism 6 is provided in the water collecting trough plate 7, and the other end extends to the outside of the water collecting trough plate 7 and is connected to an external air source.

[0105] Please see the attached Figure 7 Specifically, the air shower mechanism 6 includes an air inlet pipe 601, which is vertically arranged and keeps the bottom end connected to the external air source, and the top end passes through the water collecting trough plate 7 and remains sealed;

[0106] Two air supply pipes 602 are respectively provided on both sides of the top of the air inlet pipe 601 along the conveying direction of the conveying mechanism 2 and are connected thereto, and the other ends of the air supply pipes 602 are kept sealed;

[0107] Several exhaust pipes 603 are perpendicular to the conveying direction of the conveying mechanism 2 and are evenly arranged above the two air supply pipes 602. The two ends of the exhaust pipes 603 are sealed and the middle of the bottom end is kept connected with the air supply pipe 602. Several exhaust holes are evenly opened on the top.

[0108] According to the above paragraph, it is convenient to spray the external air source evenly toward the bottom of the conveying mechanism, thereby evenly drying the packaging containers conveyed on the conveying mechanism and improving the quality of drying.

[0109] Please combine the attached Figure 1 and attached Figure 5 Specifically, a pressing and conveying mechanism 4 is provided on the frame on both sides of the conveyor belt. The four corners of the pressing and conveying mechanism 4 are installed on the frame through height adjustment plates 5 to keep the height adjustable. A closed soft curtain 11 is provided between the frame and the pressing and conveying mechanism 4.

[0110] As described in the previous paragraph, setting up a height-adjustable pressing and conveying mechanism can facilitate adjustment according to the height of the packaging container, which not only facilitates the pressing and conveying of the packaging container, but also prevents the packaging container from being deformed by pressing. By setting up a closed soft curtain, it is prevented that when the pressing and conveying mechanism is lifted upward, the positive pressure air generated by its air shower mechanism is discharged from the gap between the pressing and conveying mechanism and the frame, thereby affecting the processing environment.

[0111] Please see the attached Figure 6 Specifically, the pressing conveying mechanism 4 includes a support frame 401, which is arranged above the conveyor belt and has long holes 402 on the four corners for maintaining movable installation with the height adjustment plate 5, and a receiving groove is opened on the opposite surface of the support frame 401 and the conveyor belt;

[0112] The compression conveyor belt 403 is arranged in the receiving groove of the support frame 401 to maintain rotation and conveyance, and there is a gap between the end of the compression conveyor belt 403 and the inner wall of the receiving groove of the support frame 401;

[0113] The exhaust pipe 404 has one end fixed on the outside of the support frame 401 and connected to the receiving groove, and the other end extending outward.

[0114] As described in the previous paragraph, setting up a compression conveyor belt can facilitate the transportation of packaging containers and press the packaging containers at the same time. Setting the gap between the receiving slots of the compression conveyor belt support frame and the exhaust pipe is to facilitate the discharge of positive pressure air in the receiving slot discharged upward by the air shower mechanism.

[0115] Furthermore, the conveying speeds of the compression conveyor belt and the conveying mechanism are the same, and the conveying directions are adapted to each other (ie, the conveying directions are opposite, which facilitates the conveying of the packaging containers).

[0116] When the air drying system is in use, first adjust the height of the automatic stacking mechanism 3 and the pressing and conveying mechanism 4 according to the size and height of the packaging container.

[0117] When adjusting the automatic stacking mechanism 3, it is only necessary to adjust the position of the movable splint 305 and the movable plate 308 by screwing the bolts and nuts and then fix them.

[0118] When adjusting the height of the pressing and conveying mechanism 4, it is only necessary to tighten the bolts and nuts so that the support frame 401 is at a suitable height of the height adjustment plate 5 and fix it.

[0119] Then the control system of the automatic stacking mechanism 3, the first drive motor 10 of the conveying mechanism 2, the drive motor in the compacting conveyor belt 403 of the pressing conveying mechanism 4, and the air source (such as a fan) connected to the air shower mechanism 6 are started to deliver cold air to the conveying surface of the conveying mechanism (because the packaging container is a plastic product, hot air may cause deformation). The conveyor belt connected to the conveying component has already transported the packaging container.

[0120] The packaging container moves between the fixed plate 307 and the movable plate 308 in the conveying assembly, passes through the through slot of the blocking portion 3047, and moves to between the fixed clamping plate 3044 and the movable clamping plate 305 of the rotating member 304, until it moves to the limiting rod 3045 for limiting, thereby realizing the stacking of the packaging container.

[0121] When the open end of the packaging container tilts upward or moves upward on the rotating member 304, it will be blocked by the height-limiting rope 309. Under the push of the subsequent packaging container, it will fall from the side of the rotating member 304 or fall into the gap between the fixed clamping plate 3044 and the movable clamping plate 305, and finally slide down from the inclined surface of the connecting portion 3043. Because the automatic stacking mechanism 3 is arranged on the feeding end of the conveying mechanism 2, and the inclined surface of the connecting portion 3043 is arranged away from the conveying mechanism 2, the packaging containers sliding down the inclined surface and the packaging containers falling from the side of the rotating member 304 will directly slide out from the head end of the conveying mechanism 2, preventing them from entering the conveying mechanism 2 for conveying.

[0122] When the sensor device does not detect infrared light within the preset time T, it sends a signal to the control system, and the control system controls the second drive motor to start, drive the worm to rotate, and under the transmission action of the worm gear transmission mechanism, drive the rotating part to rotate 180° in the conveying direction of the conveying mechanism. During the rotation process, the rotating part flips the packaging container downward with the top and the movable splint. When it reaches 180°, the packaging container loses the obstruction of the baffle and falls off to the conveying mechanism under gravity for conveying and drying. At the same time, during the rotation process, the blocking part blocks the packaging container on the conveying component and stops the conveying of the packaging container. After a certain period of time (for example, 3s), the control system controls the second drive motor to reverse. Under the transmission action of the worm gear transmission mechanism, the rotating part rotates 180° in the opposite direction to restore the rotating part to its original position. At this time, the blocking part rotates accordingly, and its through slot is between the rotating part and the conveying component, which facilitates the packaging container to pass through the through slot and move to the rotating part, and then the packaging container is stacked again.

[0123] Finally, the packaging container that falls onto the conveying mechanism (due to the limitation of the automatic stacking mechanism, the open end of the packaging container is buckled downward on the conveying surface of the conveying mechanism) is transported by the conveying mechanism 2 and enters the pressing conveying mechanism 4. The receiving groove of the packaging container comes into contact with the cold air discharged from the exhaust pipe 603 in the bottom air shower mechanism 6, and the residual water stains inside are blown out to realize the air-drying process, and finally discharged from the other end of the conveying mechanism 2. The discharged water stains pass through the conveying mechanism 2 and fall into the water collecting trough plate 7 and are discharged from the drain pipe, completing the air-drying process of the packaging container.

Any equivalent changes or modifications completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
