Description

Technical Field

[0001] This utility model relates to the field of dryer technology, and in particular to a dryer feed gate lifting device. Background Technology

[0002] With the advancement of the domestic laundry industry, competition in the laundry market is becoming increasingly fierce. As the domestic and international washing and drying markets change, the requirements for dryers in terms of technology, quality, appearance, and processes are becoming increasingly stringent. Improving and upgrading the structure of dryers to reduce costs and increase efficiency is essential to meet market demands. Currently, most dryers use a curtain-type inlet door. While this can prevent some heat loss, it easily comes into contact with washed items (clothes, curtains, etc.) during feeding, potentially soiling the clothes. Furthermore, although the curtain structure can block some heat loss, the blocking effect is poor, and heat loss remains significant.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a dryer feed gate lifting device, which optimizes the structure of the dryer feed gate and reduces heat loss.

[0005] The technical solution of this utility model is as follows: A dryer feed gate lifting device is provided, including: a gate frame, a telescopic device, a feed gate, two steel wire ropes, and two sets of pulleys; the gate frame includes: an upper horizontal frame, with left and right columns respectively arranged on the left and right sides of the upper horizontal frame; the telescopic device is installed on the upper horizontal frame, the output end of the telescopic device is connected to one end of the two steel wire ropes, and the other ends of the two steel wire ropes are respectively connected to the upper part of the feed gate; the pulleys are installed on the upper horizontal frame, and the steel wire ropes are wound around the pulleys and connected to the feed gate.

[0006] The feed gate can move up and down under the traction of a steel wire rope, thereby opening and closing the dryer. Compared with using a curtain to block the feed inlet of the dryer, it can better reduce heat loss during the drying process and achieve cost reduction and efficiency improvement.

[0007] Furthermore, the two steel wire ropes are respectively connected to the left and right sides of the feed gate, which can better maintain the stability of the feed gate.

[0008] Furthermore, both the left and right columns are provided with movable slots, and the two sides of the feed gate extend into the movable slots of the left and right columns respectively.

[0009] Furthermore, the upper crossbar includes: an upper cross plate, a reinforcing member connected to the upper cross plate; and the telescopic device and pulleys are mounted on the upper cross plate.

[0010] Furthermore, the upper crossbar also includes: a first limiting crossbar connected to the reinforcing member, and a second limiting crossbar at the top of the feed gate. The first limiting crossbar and the second limiting crossbar cooperate to limit the descent height of the feed gate.

[0011] Furthermore, the two pulley sets are connected to the output end of the same telescopic device; the two pulley sets include a first reversing pulley set and a second reversing pulley set; the first reversing pulley set includes: a first horizontally arranged pulley and a first vertically arranged pulley, and a steel wire rope passes through the first horizontally arranged pulley and the first vertically arranged pulley and is connected to the feed gate; the second reversing pulley set includes: a second horizontally arranged pulley, a third horizontally arranged pulley, and a second vertically arranged pulley, and another steel wire rope passes through the second horizontally arranged pulley, the third horizontally arranged pulley, and the second vertically arranged pulley and is connected to the feed gate.

[0012] Furthermore, the telescopic device is a pneumatic cylinder or an electric cylinder.

[0013] By adopting the above solution, this utility model provides a dryer feed door lifting device. The feed door is raised and lowered by pulling the steel wire rope through the telescopic device, which facilitates the entry of washed materials into the dryer for drying. The use of a lifting door can effectively reduce heat loss during the drying process, thereby reducing costs and increasing efficiency. Attached Figure Description
