Description

Technical Field

[0001] This utility model belongs to the field of lunch box disinfection, specifically a disinfection device for the production of plastic lunch boxes. Background Technology

[0002] Disinfection equipment for plastic lunch boxes typically includes a conveying structure for orderly transporting lunch boxes to be disinfected; it is equipped with a disinfection unit, commonly consisting of ultraviolet lamps, high-temperature steam generators, or chemical spray systems, which use ultraviolet irradiation to destroy microbial DNA, high temperatures to denature microbial proteins, and chemical reagents to act on microbial cell membranes to disinfect the lunch boxes during transport; it is also equipped with temperature control, time control, and waste liquid treatment modules to ensure disinfection effectiveness, avoid pollutant discharge, effectively remove microorganisms, and meet hygiene standards.

[0003] The existing sterilization devices for plastic lunch boxes have inherent deficiencies in their fixing structure. As a result, containers may loosen and fall off during rotation, damaging the device and contaminating the sterilization chamber. At the same time, the structural design of the sterilization devices for plastic lunch boxes may be unreasonable, leading to the creation of cleaning dead spots, which prevents some plastic lunch boxes from being thoroughly cleaned and affects product quality.

[0004] Therefore, this utility model provides a disinfection treatment device for the production of plastic lunch boxes. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A disinfection device for producing plastic lunch boxes, comprising a machine body, an internal cleaning chamber, two sets of positioning blocks welded to both sides of the cleaning chamber, the positioning blocks being engaged with the center of the machine body; a water inlet on one side of the cleaning chamber; a screw rod inside the cleaning chamber; a threaded groove welded to the top of the internal cleaning chamber, the screw rod being installed inside the threaded groove, a rotating rod welded to the bottom of the screw rod, a first connecting lug at the bottom of the rotating rod, a connecting rod on the other side of the first connecting lug, and the other end of the connecting rod... The device is equipped with a transmission gear with meshing tooth surfaces; a transmission rod is located on the other side of the transmission gear, and the transmission rod is connected to a motor; with this structural design, the motor drives the transmission rod to rotate, and then the transmission gear drives the connecting rod to swing. Through this swinging method, the threaded cylinder performs piston-like motion inside the cleaning chamber, causing the screw to rotate inside the threaded groove, thereby driving the locking structure outside the rotating rod to rotate, and simultaneously disinfecting the plastic lunch boxes fixed in the locking structure. This avoids the formation of cleaning dead corners, preventing some plastic lunch boxes from being thoroughly cleaned and affecting product quality.

[0007] Preferably, two sets of fixing discs are welded to the outside of the rotating rod, and five sets of locking structures are provided on the outside of the fixing discs. The locking structure includes a traction rod, a second connecting ear is installed on the other side of the traction rod, the second connecting ear is connected to a transmission plate, a corner of the transmission plate is connected to a fixing plate, a guide ring is welded to one side of the fixing plate, and the traction rod is slidably connected inside the guide ring; a lower clamping plate is installed on the other corner of the transmission plate, an upper clamping plate is provided on one side of the lower clamping plate, and the upper clamping plate is welded to the fixing plate; anti-slip pads are provided inside the lower clamping plate and the upper clamping plate. With this structural design, the centrifugal force generated when the rotating rod rotates pulls the traction rod, thereby causing the transmission plate to tilt up. By tilting up, the lower clamping plate is moved up, and the upper and lower clamping plates clamp the lunch box. In this way, the container is prevented from loosening and falling off during rotation, which would damage the device and contaminate the sterilization chamber.

[0008] Preferably, the outer wall of the rotating rod is welded with a cleaning chamber, and the outer wall of the cleaning chamber is provided with a threaded cylinder, which is slidably connected to the screw; a fixing ring is welded to the outer wall of the tooth surface, and the fixing ring is welded to the inside of the machine body; a control panel is provided on one side of the machine body; and a top cover is installed on the top of the machine body; this structural design increases the stability of the device operation and the disinfection effect.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. The disinfection device for producing plastic lunch boxes according to this utility model uses a motor to drive a transmission rod to rotate, which in turn drives a connecting rod to swing through a transmission gear. This swinging motion causes a threaded cylinder to perform piston-like motion inside the cleaning chamber. This causes the screw to rotate inside the threaded groove, thereby driving the locking structure outside the rotating rod to rotate. Simultaneously, the plastic lunch boxes fixed within the locking structure are disinfected, thus avoiding the formation of cleaning dead zones that prevent some plastic lunch boxes from being thoroughly cleaned, which would affect product quality.

[0011] 2. The disinfection device for producing plastic lunch boxes described in this utility model uses the centrifugal force generated when the rotating rod rotates to pull the traction rod, thereby causing the transmission plate to tilt upwards. The tilting upwards causes the lower clamping plate to move upwards, and the upper and lower clamping plates clamp the lunch box. This method avoids the problem of the container loosening and falling off during rotation, which would damage the device and contaminate the disinfection chamber. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples are given below.

[0020] like Figures 1 to 4As shown in the figure, a disinfection device for producing plastic lunch boxes according to an embodiment of the present invention includes a body 3, a cleaning chamber 2 installed inside the body 3, two sets of positioning blocks welded to both sides of the cleaning chamber 2, the positioning blocks being snapped into the center of the body 3; a water inlet 27 is opened on one side of the cleaning chamber 2; a screw 8 is provided inside the cleaning chamber 2; a threaded groove 5 is welded to the top of the cleaning chamber 2, the screw 8 is provided inside the threaded groove 5, a rotating rod 17 is welded to the bottom of the screw 8, a first connecting ear 16 is provided at the bottom of the rotating rod 17, a connecting rod 12 is provided on the other side of the first connecting ear 16, a transmission gear 13 is installed at the other end of the connecting rod 12, the transmission gear 13 meshes with the tooth surface 11; a transmission rod 14 is provided on the other side of the transmission gear 13, the transmission rod 14 is connected to a motor 15; when the device is running, the motor 15 starts, driving the transmission rod 14 to rotate; the transmission gear 13 connected to the transmission rod 14 rotates accordingly. The drive gear 13 meshes with the tooth surface 11, and the drive gear 13 is connected to the rotating rod 17 through the connecting rod 12 and the first connecting ear 16. At the same time, the screw 8 in the threaded groove 5 inside the cleaning chamber 2 is welded to the rotating rod 17, and the threaded cylinder 9 on the outer wall of the cleaning chamber 7 is slidably connected to the screw 8. When the drive gear 13 rotates, it will pull the connecting rod 12 to swing, causing the threaded cylinder 9 to perform piston movement inside the cleaning chamber 2. The piston movement of the threaded cylinder 9, in conjunction with the structure of the threaded groove 5, causes the screw 8 to rotate within the threaded groove 5, thereby driving the rotating rod 17 to rotate. The locking structure outside the rotating rod 17 (such as the fixing plate 18 and related components) rotates synchronously with the rotating rod 17. The plastic lunch box to be disinfected is fixed in the locking structure. During the rotation, it can come into contact with the disinfection environment in all directions, thereby avoiding cleaning dead corners caused by the device structure, ensuring that all parts of the plastic lunch box can be fully disinfected, and improving product quality.

[0021] Two sets of fixed discs 18 are welded to the outside of the rotating rod 17. Five locking structures are provided on the outside of the fixed discs 18. The locking structures include a traction rod 23, with a second connecting ear 25 installed on the other side of the traction rod 23. The second connecting ear 25 connects to a transmission plate 26. One corner of the transmission plate 26 is connected to a fixed plate 19. A guide ring 24 is welded to one side of the fixed plate 19, and the guide ring 24 is slidably connected to the traction rod 23 inside. A lower clamping plate 20 is installed on the other corner of the transmission plate 26. An upper clamping plate 21 is provided on one side of the lower clamping plate 20 and is welded to the fixed plate 19. Anti-slip pads 22 are provided inside the lower clamping plate 20 and the upper clamping plate 21. A cleaning chamber 7 is welded to the outside of the rotating rod 17. A threaded cylinder 9 is provided on the outer wall of the cleaning chamber 7 and is slidably connected to the screw 8. A fixing ring 10 is welded to the outside of the tooth surface 11 and is welded to the inside of the machine body 3. A control panel 4 is provided on one side of the machine body 3. A control panel 4 is installed on the top of the machine body 3. The device has a top cover 1; when the rotating rod 17 rotates, it generates centrifugal force; the fixed plate 18 welded to the outside of the rotating rod 17 also rotates with it, and the locking structure on the fixed plate 18 is subjected to centrifugal force, causing the traction rod 23 to slide within the guide ring 24; the traction rod 23 is connected to the transmission plate 26 through the second connecting ear 25, and the centrifugal force pulls the traction rod 23 to move, causing the transmission plate 26 to tilt up; the lower clamping plate 20 connected to one corner of the transmission plate 26 moves upward due to the tilting of the transmission plate 26, and the lower clamping plate 20 cooperates with the upper clamping plate 21 welded to the fixed plate 19 to clamp the plastic lunch box from the upper and lower sides; at the same time, the anti-slip pads 22 inside the lower clamping plate 20 and the upper clamping plate 21 increase the friction between them and the lunch box, further stabilizing the lunch box; through such mechanical linkage, the centrifugal force is used to clamp and fix the lunch box, preventing the lunch box from loosening or falling off during the rotation of the rotating rod 17, preventing the device from being damaged by the lunch box falling off, and also preventing the disinfection chamber from being contaminated.

[0022] During operation, the motor 15 starts, driving the transmission rod 14 to rotate. The transmission gear 13 connected to the transmission rod 14 rotates accordingly. Because the transmission gear 13 meshes with the tooth surface 11, and the transmission gear 13 is connected to the rotating rod 17 through the connecting rod 12 and the first connecting ear 16, the screw 8 in the threaded groove 5 inside the cleaning chamber 2 is welded to the rotating rod 17, and the threaded cylinder 9 on the outer wall of the cleaning chamber 7 is slidably connected to the screw 8. When the transmission gear 13 rotates, it pulls the connecting rod 12 to swing, causing the threaded cylinder 9 to perform piston movement inside the cleaning chamber 2. The piston movement of the threaded cylinder 9, in conjunction with the structure of the threaded groove 5, causes the screw 8 to rotate within the threaded groove 5, thereby driving the rotating rod 17 to rotate. The locking structure outside the rotating rod 17 (such as the fixing plate 18 and related components) rotates synchronously with the rotating rod 17, fixing the plastic lunch box to be disinfected within the locking structure. During rotation, it can come into contact with the disinfection environment from all directions, thereby avoiding cleaning dead corners caused by the structure of the device and ensuring the cleanliness of the plastic lunch box. All parts of the box can be thoroughly disinfected, improving product quality. When the rotating rod 17 rotates, it generates centrifugal force. The fixed plate 18 welded to the outside of the rotating rod 17 also rotates with it. The locking structure on the fixed plate 18 is subjected to centrifugal force, and the traction rod 23 slides in the guide ring 24. The traction rod 23 is connected to the transmission plate 26 through the second connecting ear 25. The centrifugal force pulls the traction rod 23 to move, causing the transmission plate 26 to tilt. The lower clamping plate 20 connected to one corner of the transmission plate 26 moves upward due to the tilting of the transmission plate 26. The lower clamping plate 20 cooperates with the upper clamping plate 21 welded to the fixed plate 19 to clamp the plastic lunch box from the top and bottom. At the same time, the anti-slip pads 22 inside the lower clamping plate 20 and the upper clamping plate 21 increase the friction between them and the lunch box, further stabilizing the lunch box. Through such mechanical linkage, the centrifugal force is used to clamp and fix the lunch box, preventing the lunch box from loosening or falling off during the rotation of the rotating rod 17, preventing damage to the device due to the lunch box falling off, and also preventing the disinfection chamber from being contaminated.
