Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0026] As Figure 1 shown:

[0027] The precision temperature control carton drying production equipment includes a drying oven 1 and a conveyor 2 installed inside the drying oven 1.

[0028] In this implementation: The existing precision temperature control carton drying production equipment {Publication (Announcement) Number}: CN208194847U discloses a drying device for packaging carton production; to solve the technical problems existing in this prior art, as disclosed in the background art above, "Although this design can provide pressure for drying the packaging carton and quickly dry the adhesive on the surface of the packaging carton, during the carton drying process, due to the lack of effective positioning and supporting means, the carton is prone to wrinkling and deformation, which will seriously affect the appearance quality and service performance of the carton. The appearance of wrinkles not only reduces the aesthetics of the carton but also may cause the structure of the dried carton to be unstable, and it is prone to deformation or even damage in subsequent packaging, storage, and transportation processes." In combination, this problem is obviously a real and difficult-to-solve problem. In view of this, to solve this technical problem, a positioning assembly 3 and a flipping assembly 4 are added in this application document.

[0029] As Figures 1 - 5 shown:

[0030] Combined with the above content, in order to prevent the carton material from being easily wrinkled due to uneven heating during drying, it further includes a positioning component 3 installed on both sides inside the drying box 1. The positioning component 3 includes a positioning frame 31, positioning wheels 32, extrusion tooth plates 33, extrusion gears 34, a rotating shaft 35, a driving motor 36, an electric push rod 37, a pressing frame 38, a pressing roller 39, moving blocks 310, a first spring 311, and a pressure sensor 312;

[0031] Positioning frames 31 are symmetrically arranged on both sides inside the drying box 1. A number of groups of equally spaced positioning wheels 32 are rotatably connected inside the positioning frames 31. A rotating shaft 35 is rotatably connected to one side of the drying box 1 close to the positioning frame 31. Two ends of the surface of the rotating shaft 35 are symmetrically fixed with extrusion gears 34. The surfaces of the extrusion gears 34 are meshed with extrusion tooth plates 33. A moving groove adapted to the extrusion tooth plate 33 is formed inside the drying box 1, and the end of the extrusion tooth plate 33 is fixedly connected to the surface of the positioning frame 31. The surface of the drying box 1 is screwed with a driving motor 36, and the output shaft of the driving motor 36 is fixedly connected to the end of the rotating shaft 35. A number of groups of equally spaced electric push rods 37 are fixedly arranged at the top of the inner cavity of the drying box 1. The output ends of the electric push rods 37 are fixedly connected with a pressing frame 38. A pressing roller 39 is arranged inside the pressing frame 38. Two sides inside the pressing frame 38 are symmetrically slidably connected with moving blocks 310, and the pressing roller 39 is rotatably connected between the two moving blocks 310. A first spring 311 is fixed on the surface of the moving block 310, and the other end of the first spring 311 is fixedly connected with a pressure sensor 312 between the pressing frame 38, and the pressure sensor 312 is electrically connected to the electric push rod 37.

[0032] In this implementation: When it is necessary to dry the cardboard box, first turn on the drying box 1 and the conveyor 2, and then place the cardboard box to be processed on the surface of the conveyor 2. Through the conveyance of the conveyor 2, the cardboard box can be evenly fed into the interior of the drying box 1. When the cardboard box enters the front interior of the drying box 1, by turning on the corresponding drive motor 36 and the electric push rod 37, when the drive motor 36 is started, it can drive the rotating shaft 35 to rotate outside the drying box 1, and then drive the extrusion gear 34 on its surface to rotate, thereby driving the extrusion tooth plate 33 to slide in the moving groove opened inside the drying box 1, which can drive the positioning frame 31 and the positioning wheel 32 to move synchronously and approach the surface of the cardboard box. When the positioning wheel 32 contacts the surface of the cardboard box, it can position and support the side surface of the cardboard box. During this period, by starting the electric push rod 37, it can push the pressing frame 38 to drive the pressing roller 39 to approach the upper surface of the cardboard box. When the pressing roller 39 contacts the surface of the cardboard box, it can drive the moving block 310 to slide inside the pressing frame 38, and then squeeze the first spring 311 to deform and generate elastic force, thereby squeezing the pressure sensor 312 to generate a piezoelectric signal. When the piezoelectric signal generated by the pressure sensor 312 reaches the threshold value, the electric push rod 37 will be automatically turned off, and the pressing roller 39 can be stopped and maintained at an appropriate position height, so as to press and position the cardboard box, thereby ensuring the appearance quality of the cardboard box and preventing the cardboard box material from being easily wrinkled due to uneven heating during drying.

[0033] Furthermore:

[0034] Combined with the above content, in order to avoid the situation of insufficient local drying or over-drying, it further includes a flipping assembly 4 installed in the middle side inside the drying box 1. The flipping assembly 4 includes an electric telescopic rod 41, a flipping rack 42, a limit sliding seat 43, a flipping gear 44, a flipping shaft 45, a flipping plate 46, a clamping push rod 47, an extrusion plate 48, a second spring 49 and a clamping plate 410;

[0035] A limit sliding seat 43 is arranged between the two rotating shafts 35, and the limit sliding seat 43 is fixed in the middle of the outer side of the drying box 1. The flipping rack 42 is slidably connected inside the limit sliding seat 43. The end of the flipping rack 42 is fixed with an electric telescopic rod 41, and the electric telescopic rod 41 is screwed to the surface of the drying box 1. The surface of the flipping rack 42 is meshed with a flipping gear 44. The flipping gear 44 is internally fixed with a flipping shaft 45, and the flipping shaft 45 is rotatably connected inside the drying box 1. One end of the flipping shaft 45 away from the flipping gear 44 is fixed with a flipping plate 46. The other side of the flipping plate 46 is fixed with two clamping push rods 47. The output end of the clamping push rod 47 is fixed with an extrusion plate 48. Clamping plates 410 are arranged on the opposite sides of the two extrusion plates 48, and a number of second springs 49 arranged at equal intervals are fixed between the clamping plates 410 and the extrusion plates 48.

[0036] In this embodiment, as the carton is continuously transported, the positioning wheel 32 and the pressing roller 39 will roll along the surface of the carton. When the carton is separated from the surface of the positioning wheel 32 and the pressing roller 39 and moves to the position of the clamping plate 410, the clamping push rod 47 is opened, and the clamping push rod 47 pushes the squeezing plate 48 to drive the clamping plate 410 toward the surface of the carton. When the clamping plate 410 contacts the surface of the carton, under the buffering effect of the spring 49, it can avoid the clamping force being too large in an instant to damage the carton, and prevent the rigid clamping from causing the carton to be The box is deformed, cracked or even completely damaged, ensuring that the carton can be firmly fixed during the clamping process without being damaged by excessive squeezing. After the carton is clamped, the electric telescopic rod 41 is started, and the electric telescopic rod 41 pushes the flip rack 42 to slide inside the limiting slide 43, thereby driving the flip gear 44 and the flip shaft 45 to rotate on the surface of the drying box 1, and then driving the flip plate 46 to rotate synchronously, which can drive the clamping plate 410 and the clamped carton to flip, so that all surfaces can be fully exposed to heat.

[0037] It should be noted that by turning the carton, moisture accumulation can be prevented. If it is not turned over, moisture may accumulate on some sides of the carton due to gravity, causing that side to dry slowly. After turning over, the moisture can be more evenly distributed and evaporated, speeding up the drying process.

[0038] Working principle and usage process of the utility model: When it is necessary to dry the cardboard box, first turn on the drying box 1 and the conveyor 2, and then place the cardboard box to be processed on the surface of the conveyor 2. Through the conveyance of the cardboard box by the conveyor 2, the cardboard box can be evenly fed into the interior of the drying box 1. When the cardboard box enters the front interior of the drying box 1, by turning on the corresponding drive motor 36 and the electric push rod 37, when the drive motor 36 is started, it can drive the rotating shaft 35 to rotate outside the drying box 1, and then drive the extrusion gear 34 on its surface to rotate, thereby driving the extrusion tooth plate 33 to slide in the moving groove opened inside the drying box 1, which can drive the positioning frame 31 and the positioning wheel 32 to move synchronously and approach the surface of the cardboard box. When the positioning wheel 32 touches the surface of the cardboard box, it can position and support the side surface of the cardboard box. During this period, by starting the electric push rod 37, it can push the pressing frame 38 to drive the pressing roller 39 to approach the upper surface of the cardboard box. When the pressing roller 39 touches the surface of the cardboard box, it can drive the moving block 310 to slide inside the pressing frame 38, thereby squeezing the first spring 311 to deform and generate elastic force, which in turn squeezes the pressure sensor 312 to generate a piezoelectric signal. When the piezoelectric signal generated by the pressure sensor 312 reaches the threshold value, the electric push rod 37 will be automatically turned off, and the pressing roller 39 can be stopped and maintained at an appropriate position height, so as to press and position the cardboard box, thereby ensuring the appearance quality of the cardboard box, preventing the cardboard box material from being easily wrinkled due to uneven heating and other reasons during drying. The positioning and support can ensure the flatness of the cardboard box surface, improve the aesthetics of the cardboard box, maintain the stability of the cardboard box structure after drying, make the cardboard box always maintain the designed shape during the drying process, ensure the use performance, extend the service life of the cardboard box, avoid deformation or even damage in subsequent packaging, storage, transportation and other links, improve its load-bearing capacity, and the flat cardboard box structure is more solid and can withstand greater pressure and weight. During stacking storage or transportation, it is not easy to collapse or deform, protecting the safety of the internal items, making the drying link more stable and reliable, contributing to the smooth progress of the entire production process, and improving the overall production efficiency.

[0039] As the carton is continuously conveyed, the positioning wheel 32 and the pressing roller 39 will roll along the surface of the carton. When the carton disengages from the surfaces of the positioning wheel 32 and the pressing roller 39 and moves to the position where the clamping plate 410 is located, by activating the clamping push rod 47, the clamping push rod 47 pushes the extrusion plate 48 to drive the clamping plate 410 to approach the surface of the carton. When the clamping plate 410 contacts the surface of the carton, under the buffering action of the second spring 49, it can avoid the clamping force being instantaneously too large and damaging the carton, preventing the carton from deforming, cracking or even being completely damaged due to rigid clamping, ensuring that the carton can be firmly fixed during the clamping process without being damaged due to excessive extrusion. When the clamping of the carton is completed, by starting the electric telescopic rod 41, the electric telescopic rod 41 pushes the flipping rack 42 to slide inside the limit sliding seat 43, thereby driving the flipping gear 44 and the flipping shaft 45 to rotate on the surface of the drying box 1, and then driving the flipping plate 46 to rotate synchronously, which can drive the clamping plate 410 and the clamped carton to flip, enabling each surface to fully contact the heat, ensuring that each surface is uniformly heated, avoiding the situation of insufficient or excessive drying in some parts, thereby improving the overall drying uniformity, and being able to reduce the risk of carton deformation, avoiding the carton from shrinking during the drying process. If only one side is heated, it is easy to cause uneven shrinkage and deformation. Flipping and drying all sides can make the shrinkage degree of each surface of the carton more consistent, reducing deformation problems such as wrinkles and twists caused by shrinkage differences. When the flipping is completed, by releasing the clamping of the carton, the carton can be placed on the surface of the conveyor 2 to continue the conveyance. When the carton moves to the position of the positioning wheel 32 and the pressing roller 39 at the rear end, it will be positioned and supported again, thereby ensuring the structural stability of the carton during the drying process.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
