Description

Technical Field

[0001] The utility model relates to the technical field of bottle cap production equipment, in particular to a drying equipment for PP bottle cap production. Background Art

[0002] PP bottle caps have good heat resistance and durability. They can remain unchanged in hot water at 100°C, and are resistant to acid, alkali and wear. This allows bottle caps made of PP material to maintain good use status for a long time. Bottle caps are a common packaging form for bottles, cans and barrels, especially in the fields of beverages, chemicals and medicine. According to their uses, they can be divided into breathable plastic caps and impermeable plastic caps. Plastic caps generally use polyolefins as the main raw material and are processed and formed through injection molding, hot pressing and other processes. After the bottle caps are produced and cleaned, they need to be dried.

[0003] The currently published patent: CN219003510U discloses a drying device for spraying bottle caps. The drying device for spraying bottle caps is provided with a drying mechanism. Through the cooperation between the various structures of the drying mechanism, the bottle caps after spraying can be dried. Through the operation of the heating tube and the fan, the hot air is directed to the bottle caps after spraying to dry the bottle caps, so as to improve the effect of the equipment during spraying.

[0004] Based on the above search, it was found that the above patent has the following problems when in use: when in use, the drying equipment for spraying bottle caps can direct hot air to the top of the bottle caps after spraying through the operation of the heating tube and the fan, but cannot direct the air to the bottom of the bottle caps, thereby causing the top of the bottle caps to dry faster and the bottom of the bottle caps to dry slower, affecting the uniformity of drying the bottle caps.

[0024] See also Figure 1-4 The utility model provides a technical solution: a drying device for producing PP bottle caps, comprising a drying rack 1 and a bidirectional drying device, two conveying rollers 2 are rotatably installed on the top of the drying rack 1, and a conveying net 3 is rotatably installed on the surface of the two conveying rollers 2;

[0025] The top of the drying rack 1 is fixedly connected to two guard plates 9, the tops of the two guard plates 9 are fixedly connected to a PP bottle cap automatic unloading box 10, the tops of the two guard plates 9 are fixedly connected to a connecting bridge 11, the top of the connecting bridge 11 is provided with a slide groove 12, the inside of the slide groove 12 is slidably connected to a slide table 13, the bottom of the slide table 13 is fixedly connected to two bulk material push rods 14, the top of the slide table 13 is fixedly connected to a protrusion 15, the top of the connecting bridge 11 is fixedly installed with an electric telescopic rod 16, and the output end of the electric telescopic rod 16 is fixedly connected to the top of the protrusion 15.

[0026] After the staff puts the PP bottle caps into the PP bottle cap automatic unloading box 10, the PP bottle caps automatically slide down to the top of the conveyor net 3 due to their own gravity. A transmission device is provided inside the drying rack 1, which can drive the two conveyor rods 2 to rotate. The rotation of the two conveyor rods 2 can drive the conveyor net 3 to rotate. The rotation of the conveyor net 3 can drive the top PP bottle caps to gradually move to the right. After the staff starts the electric telescopic rod 16, the output end of the electric telescopic rod 16 slides first to drive the protrusion 15 to slide back and forth. The sliding of the protrusion 15 can drive the slide 13 and the two bulk material push rods 14 to slide back and forth to evacuate the PP bottle caps on the top of the conveyor net 3, thereby preventing the PP bottle caps from piling up on the surface of the conveyor net 3, so that the PP bottle caps are evenly distributed on the surface of the conveyor net 3, which is convenient for hot air to blow on the surface of the PP bottle caps for drying.

[0027] The bidirectional drying device includes a blower 4, an exhaust rigid pipe 5, two exhaust elbows 6, two exhaust hoods 7 and a heating pipe 8. The blower 4 is fixedly installed on the surface of the drying rack 1, the exhaust rigid pipe 5 is fixedly installed on the output end of the blower 4, the two exhaust elbows 6 are both fixedly installed on the surface of the exhaust rigid pipe 5, the two exhaust hoods 7 are respectively fixedly installed on the rear ends of the two exhaust elbows 6, and the heating pipe 8 is fixedly installed inside the exhaust hood 7.

[0028] After the conveying net 3 drives the top PP bottle cap to move to the position of the two exhaust hoods 7, the staff starts the blower 4. The blower 4 first exhausts air into the exhaust hard pipe 5, and discharges the air into the two exhaust curved pipes 6 through the exhaust hard pipe 5, and then discharges the air to the inside of the two exhaust hoods 7 through the two exhaust curved pipes 6. At this time, the heating pipe 8 heats the air inside the exhaust hood 7, and blows the heated air to the upper and lower surfaces of the PP bottle caps through the wind. Since the surface of the conveying net 3 is provided with air holes, the exhaust hood 7 on the lower side can blow the hot air through the conveying net 3 to the bottom of the PP bottle cap. In this way, the hot air can be blown to the upper and lower surfaces of the PP bottle cap, so that the top and bottom of the bottle cap are dried at the same speed, thereby improving the uniformity of the drying of the PP bottle caps and improving the production quality of the PP bottle caps.

[0029] Working principle: The drying equipment for PP bottle cap production, after the staff puts the PP bottle cap into the PP bottle cap automatic unloading box 10, the PP bottle cap automatically slides down to the top of the conveyor net 3 by its own gravity, and the two conveyor rollers 2 can be driven to rotate by the transmission device, and the rotation of the two conveyor rollers 2 can drive the conveyor net 3 to rotate, and the rotation of the conveyor net 3 can drive the top PP bottle cap to gradually move to the right, and the output end sliding of the electric telescopic rod 16 first drives the protrusion 15 to slide back and forth, and the sliding of the protrusion 15 can drive the slide 13 and the two bulk material push rods 14 to slide back and forth to evacuate the PP bottle caps on the top of the conveyor net 3. After the staff starts the blower 4, the blower 4 first exhausts air into the exhaust hard pipe 5, and discharges the air into the two exhaust bend pipes 6 through the exhaust hard pipe 5, and exhausts the air to the inside of the two exhaust hoods 7 through the two exhaust bend pipes 6, and blows the heated air to the upper and lower surfaces of the PP bottle caps through the wind, so that the top and bottom of the bottle caps are dried at the same speed, thereby improving the uniformity of the drying of the PP bottle caps.
