Description

Technical Field

[0001] The utility model relates to a pretreatment device for spinning chips, belonging to the technical field of chip storage. Background Art

[0002] In the field of spinning, chips are one of the important raw materials in the spinning production process. Chips usually refer to small particles made of polymers such as polyester or other plastic materials. These particles are melted in a spinning machine and then ejected through a spinneret to form slender fibers. Usually, the chips need to be transported from the production site or warehouse to the spinning factory by freight vehicles and stored in the stock bin of the factory. However, the chips are easily affected by the environmental humidity during transportation. If the humidity is too high, the chips will absorb moisture, which may affect the subsequent production quality if not processed in time. Content of the Utility Model

Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0019] Please refer to Figures 1 to 3 , a spinning slice pretreatment device in this embodiment includes a drying unit and a dehumidifying unit.

[0020] The drying unit includes a first blower 11, a heater 12 and a feeding pipe 13. The first blower 11 and the second heater 12 are connected in series to the feeding pipe 13 in sequence. An inlet pipe 14 is provided at a position downstream of the heater 12 on the feeding pipe 13. During operation, the first blower 11 sends air into the feeding pipe 13 and the air is heated by the heater 12, enters the spinning chips through the inlet pipe 14, is wrapped by the hot air and dried while moving forward.

[0021] The dehumidifying unit includes a dehumidifying cylinder 21, a dehumidifying pipe 22 and a second blower 23. The dehumidifying cylinder 21 is fixedly sleeved on the feeding pipe 13. A plurality of dehumidifying openings 24 are formed on the outer wall surface of the feeding pipe 13 located inside the dehumidifying cylinder 21. The diameters of these dehumidifying openings 24 are smaller than the size of the chips. A dehumidifying pipe 22 is provided on the dehumidifying cylinder 21, and a second blower 23 is provided on the dehumidifying pipe 22. Through the action of the dehumidifying pipe 22 and the second blower 23, the high-temperature and high-humidity air after drying the chips can be extracted, preventing it from entering the storage bin with the chips and causing the chips to become damp again.

[0022] To ensure the dehumidifying function, the dehumidifying unit further includes a scraping ring 25, a support arm 26 and a driving mechanism 27. The scraping ring 25 is movably arranged inside the feeding pipe 13. Two symmetric strip-shaped openings 28 are provided on the feeding pipe 13. One end of the support arm 26 is connected to the scraping ring 25, and the other end passes through the strip-shaped opening 28 and is connected to the driving mechanism 27. The driving mechanism 27 is an electric cylinder. The bottom of the electric cylinder is fixed inside the dehumidifying cylinder 21, and the telescopic rod of the electric cylinder is connected to the support arm 26. By driving the support arm 26 to move up and down through the driving mechanism 27, the scraping ring 25 is driven to move up and down inside the feeding pipe 13, scraping off the chips attached to the inside of the feeding pipe 13 due to suction and ensuring the smoothness of the dehumidifying function.

[0023] To prevent the chips from discharging from the strip-shaped opening 28, sliding grooves 29 are provided on the upper and lower parts of the inner wall of the feeding pipe 13 corresponding to the strip-shaped opening 28. Corresponding sliding strips 30 are provided at the upper and lower positions of the scraping ring 25. The sliding strips 30 are slidably installed in the sliding grooves 29, and the length of the sliding strips 30 is greater than the length of the strip-shaped opening 28. Thus, when the scraping ring 25 moves up and down, the sliding strips 30 always close the strip-shaped opening 28, preventing the chips from flowing out of the strip-shaped opening 28.

[0024] To facilitate operation, the feeding pipe 13 includes a connected horizontal pipe section 131 and a vertical pipe section 132, and the dehumidifying cylinder 21 is fixed on the vertical pipe section 132.

[0025] The working principle of the above spinning chip pretreatment device is as follows:
