Description

Technical Field

[0001] This utility model relates to the field of plastic bottle processing technology, specifically to a quick-drying device for plastic bottles. Background Technology

[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. Plastic bottles widely use polyester (PET), polyethylene (PE), and polypropylene (PP) as raw materials, adding appropriate organic solvents, and then heating at high temperatures before being molded into plastic containers through blow molding, extrusion blow molding, or injection molding.

[0003] In the production process of plastic bottles, in order to improve the purity of the plastic bottles, it is necessary to clean them. However, existing drying devices for plastic bottle production, such as the patent CN219160877U, require waiting for all the plastic bottles to enter the drying hood before the drying process can begin. This results in low continuous processing performance and low drying efficiency, which is not conducive to production. To address the above problems, a fast drying device for plastic bottles is proposed. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a quick-drying device for plastic bottles, which solves the problem that the current continuous processing performance is low, resulting in low drying efficiency of plastic bottles, which is not conducive to production and use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a quick-drying device for plastic bottles, comprising a base plate, a support frame fixedly connected to the upper surface of the base plate, a transfer assembly fixedly installed above the support frame, two fixed rods fixedly connected to the middle of the support frame, a connecting plate fixedly connected between the two fixed rods, three sets of clamping assemblies fixedly connected above the connecting plate, each clamping assembly comprising a conical cylinder fixedly connected to the connecting plate, a through hole penetrating the bottom surface of the connecting plate at the position of the conical cylinder, a branch pipe fixedly connected between the two fixed rods and below the connecting plate, and an air outlet nozzle adapted to the number of clamping assemblies fixedly connected above the branch pipe, the output end of the air outlet nozzle passing through the through hole and extending into the interior of the conical cylinder.

[0006] Preferably, a centrifugal fan is fixedly connected to the left side of the upper surface of the base plate, and a heating box is fixedly connected to the output end of the centrifugal fan through a pipe. An air inlet pipe is fixedly connected to the front side of the heating box, and the upper end of the air inlet pipe is connected to the front end of the branch pipe. A placement rack is fixedly connected to the left side of the support frame, and a guide plate is fixedly connected to the right side of the support frame.

[0007] Preferably, four sets of sliding rods are slidably connected to the outer wall of the conical cylinder. Each of the four sliding rods is fixedly connected to a clamping block at one end inside the conical cylinder. A compression spring is sleeved on the outer side of each of the four sliding rods. One end of the compression spring is fixedly connected to the clamping block, and the other end of the compression spring is fixedly connected to the inner wall of the conical cylinder.

[0008] Preferably, the transfer component includes a mounting frame, which is fixedly connected to the top of the support frame. Movable guide rails are fixedly connected to both the front and rear sides of the upper surface of the mounting frame. Movable plates are slidably connected to the left and right sides above the two movable guide rails. The two movable plates are fixedly connected to each other by a connecting rod.

[0009] Preferably, two limiting rods are slidably connected to the upper surface of both movable plates, and a fixed plate is fixedly connected to the lower end of the two limiting rods. A pushing cylinder is fixedly connected to the middle of the upper surface of both movable plates, and the output end of the pushing cylinder passes through the movable plate and is fixedly connected to the top of the fixed plate.

[0010] Preferably, at least three sets of connectors are fixedly connected to the bottom of the fixing plate, and a bidirectional telescopic cylinder is fixedly connected to the bottom of each of the three sets of connectors. An arc-shaped clamping frame is fixedly connected to both output ends of the bidirectional telescopic cylinder.

[0011] Preferably, two fixed seats are fixedly connected to the rear side of the upper surface of the mounting frame, a threaded rod is rotatably connected between the two fixed seats at the middle, and guide rods are fixedly connected to both the front and rear sides of the two fixed seats. A moving block is threadedly connected to the outer surface of the threaded rod, the moving block is slidably connected to the guide rod, a connecting block is fixedly connected above the moving block, and the connecting block is fixedly connected to the rear end of the left moving plate. A servo motor for driving the threaded rod to rotate is fixedly installed on the side of at least one fixed seat.

[0012] Compared with existing technologies, the advantages of this invention are as follows: By incorporating a transfer component, this invention utilizes a servo motor, a push cylinder, and a bidirectional telescopic cylinder to simultaneously load undried plastic bottles and unload dried plastic bottles. This simultaneous loading and unloading ensures continuous operation of the production line, preventing production stoppages due to waiting for drying or loading. This parallel operation minimizes idle time during production, thereby improving overall production efficiency. In traditional production models, it is typically necessary to wait for a batch of plastic bottles to dry before unloading and the next round of loading. Simultaneous loading and unloading, through effective time allocation, reduces the cycle time of individual batches, thus shortening the overall production cycle and increasing the overall output of the production line.

[0025] Furthermore, a centrifugal fan 8 is fixedly connected to the left side of the upper surface of the base plate 1. The output end of the centrifugal fan 8 is fixedly connected to a heating box 9 through a pipe. The heating box 9 is existing technology and will not be described in detail here.

[0028] Furthermore, two limiting rods 1304 are slidably connected to the upper surfaces of the two movable plates 1303, and a fixed plate 1305 is fixedly connected to the lower ends of the two limiting rods 1304.

Each of the three sets of connectors 1306 is fixedly connected to a bidirectional telescopic cylinder 1307. Both output ends of the bidirectional telescopic cylinder 1307 are fixedly connected to an arc-shaped clamping frame 1308. The arc-shaped clamping frame 1308 can adapt to plastic bottles of different sizes, ensuring the stability and safety of clamping. The bidirectional telescopic cylinder 1307 can be an Airtac STMB slide table double rod double axis cylinder.

[0030] Furthermore, two fixed seats 1310 are fixedly connected to the rear side of the upper surface of the mounting frame 1301.

[0031] Working principle: When drying plastic bottles, the bottles are first placed upside down on the rack 3. Then, the cylinder 1309 pushes the fixing plate 1305 downwards until the arc-shaped clamping frame 1308 can clamp the plastic bottle at the desired height. Next, the output ends of both sides of the bidirectional telescopic cylinder 1307 retract synchronously, thus using the arc-shaped clamping frame 1308 to hold the plastic bottle. The arc-shaped clamping frame 1308 below the left moving plate 1303 can clamp the undried plastic bottles above the rack 3. The arc-shaped clamping frame 1308 below the right-side movable plate 1303 can clamp the dried plastic bottle above the clamping assembly 7. After clamping, the cylinder 1309 is pushed as a power source to lift the plastic bottle. Then, the servo motor 1313 drives the threaded rod 1311 to rotate. Through the threaded engagement with the movable block 1314, the connecting block 1315 drives the left-side movable plate 1303 to move to the right. Under the action of the connecting rod 1316, the two movable plates 1303 will move synchronously. When the left movable plate 1303 moves above the clamping assembly 7, the cylinder 1309 is used as a power source to insert the plastic bottle into the middle of the four clamping blocks 703. Since the bottle mouth is generally conical, the bottle body will push the four clamping blocks 703 apart, thereby using the elastic force of the compression spring 704 to clamp the plastic bottle. At this time, the right movable plate 1303 will move above the guide plate 4, and the bidirectional telescopic cylinder 1307 will release the clamping of the arc-shaped clamping frame 1308. After drying, the plastic bottles will slide out above the guide plate 4. The undried plastic bottles will be inserted into the middle of the clamping assembly 7. Then, the cylinder 1309 is pushed to pull the arc-shaped clamping frame 1308 upward. The servo motor 1313 serves as the power source to restore the two moving plates 1303 to their original positions. At this time, the centrifugal fan 8 blows air into the heating box 9. After being heated, the air flows through the air inlet pipe 10 and the branch pipe 11 in sequence, and then is blown into the plastic bottle through the air outlet 12 for rapid drying.
