Description

Technical Field

[0001] This utility model relates to the field of paper lunch box mold technology, specifically a paper lunch box tableware mold. Background Technology

[0002] Fast food requires multiple containers to hold rice and dishes. Most existing plates are reusable, but there is also a need for disposable plates, which are generally injection molded from plastic. Pulp molding is currently the main method for producing pulp molded tableware; existing paper food containers are usually produced by casting, typically involving the simultaneous casting of multiple containers using a heated stamping process.

[0003] Patent CN212073108U discloses a forming mold for paper lunch boxes, including an upper mold and a lower mold. The lower mold is mounted on a base, and two columns are provided on the upper end of the base.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1 to 5 As shown, a paper lunch box tableware mold includes an upper mold 1, a lower mold 2, and a base plate 21 connected to the bottom of the lower mold 2. A cleaning component 3 is connected above the lower mold 2. The cleaning component 3 includes a cleaning pipe 301. Several nozzles 302 are connected to the outside of the cleaning pipe 301. An air inlet pipe 304 is fixedly connected to the outside of the cleaning pipe 301. An air compressor is connected to the air inlet pipe 304. Side supports 303 are connected to both ends of the cleaning pipe 301. Movable components are connected to the bottom of the two side supports 303.

[0023] like Figure 1 As shown, the paper lunchbox tableware mold in this utility model is similar in structure to existing forming molds for paper lunchbox tableware. For example, patent publication number CN212073108U discloses a forming mold for paper lunchbox tableware. The main improvement of this utility model is that it facilitates the cleaning of the lower mold before the next thermoforming process. Figures 1 to 5 As shown, when the paper lunch box and tableware mold of this utility model is in use, after the upper mold 1 completes one thermoforming cycle and is lifted to separate from the lower mold 2, the moving component is activated, causing the cleaning pipe 301 to move. This moves multiple nozzles 302, side supports 303, and air inlet pipe 304 simultaneously. The nozzles 302 blow the top surface of the lower mold 2, while the air compressor connected to the air inlet pipe 304 can spray high-pressure gas from the nozzles 302 to blow away impurities adhering to the lower mold 2, thereby cleaning the lower mold 2 and ensuring that the product after the next thermoforming cycle of the lower mold 2 is free of indentations, thus ensuring the product qualification rate.

[0024] After the cleaning tube 301 completes one movement, it will return to its original position, which not only cleans the lower mold 2 again, but also facilitates the next cleaning.

[0025] By setting a cleaning pipe 301, a nozzle 302, an air inlet pipe 304, and an air compressor above the lower mold 2, the nozzle 302 can blow out high-pressure gas to blow away impurities adhering to the lower mold 2, thereby cleaning the lower mold 2 and ensuring that the product after the next thermoplastic treatment of the lower mold 2 will not have indentation problems, thus ensuring the product qualification rate.

[0026] It is worth noting that the air compressor equipment is a mature existing air compressor equipment, so it will not be discussed in detail here.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the movable component includes a mounting box 4. The top of the mounting box 4 has a transverse groove 41 corresponding to the position of the side bracket 303. A forward and reverse motor 6 is fixedly installed inside the mounting box 4. The output end of the forward and reverse motor 6 is fixedly connected to a threaded rod 9 that is rotatably connected to the mounting box 4. A threaded ring 8 that is fixedly connected to the bottom of the side bracket 303 is threadedly connected to the outer side of the threaded rod 9.

[0028] Specifically, when the side support 303 needs to move with the cleaning tube 301, the output shaft of the forward and reverse motor 6 rotates, driving the threaded rod 9 to rotate and connect with the threaded ring 8. The threaded ring 8 drives the side support 303 to move under the restriction of the transverse groove 41, thereby driving the cleaning tube 301 to move above the lower mold 2. When the forward and reverse motor 6 reverses, the side support 303 will return to the opposite direction of the transverse groove 41, thus completing the cleaning of the lower mold 2.

[0029] It is worth noting that the forward and reverse motor 6 is a mature existing technology, so it will not be discussed in detail here.

[0030] like Figure 3 , Figure 4 and Figure 5 As shown, the cleaning tube 301 is fixedly connected to both ends of the mounting column 7, the mounting column 7 passes through the side bracket 303 and is rotatably connected to it, and the outer wall of the side bracket 303 is connected to the actuating component 5.

[0031] Specifically, during the movement of the cleaning tube 301, by moving the component 5, the cleaning tube 301 can rotate at a certain angle between the mounting column 7 and the side bracket 303. This setting allows the nozzle 302 at the bottom of the cleaning tube 301 to swing slightly and blow clean the surface of the lower mold 2, resulting in a better cleaning effect.

[0032] like Figure 1 , Figure 3 and Figure 4As shown, the actuating assembly 5 includes two pulleys 501. One of the pulleys 501 is fixedly sleeved on the outside of the mounting post 7, and the other pulley 501 is rotatably connected to the outer wall of the side bracket 303. A transmission belt 503 is sleeved between the two pulleys 501. A gear 502 is fixedly connected to the outside of the pulley 501 rotatably connected to the outer wall of the side bracket 303. An intermittent rack plate 504 that meshes with the gear 502 is fixedly connected to the top surface of the mounting box 4.

[0033] Specifically, when the side bracket 303 moves, the gear 502 meshes with the intermittent rack plate 504. The rotation of the gear 502 drives the pulley 501 connected to it to rotate, which in turn drives another pulley 501 to rotate, thereby driving the mounting column 7 to rotate and connect within the top of the side bracket 303.

[0034] Because the intermittent rack plate 504 is set intermittently, the gear 502 will rotate when it is engaged with it. When it is not engaged, the nozzle 302 will be aligned downward with the lower mold 2 due to gravity. Thus, as the side bracket 303 moves, the cleaning tube 301 will rotate and fall continuously with the mounting column 7, so that the sprayed airflow forms a dynamic airflow in the swinging state, which helps to loosen the adhering impurities. At the same time, it can be used in different grooves, which can improve the cleaning effect.

[0035] like Figure 4 and Figure 5 As shown, the inner walls of the transverse groove 41 are fitted to the outer walls of the side support 303. This arrangement allows the side support 303 to move more smoothly.

[0036] like Figure 1 and Figure 2 As shown, the mounting box 4 is located on the top surface of the base plate 21 and is detachably connected to the base plate 21. This design facilitates the installation and removal of the mounting box 4.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
