Description

Technical Field

[0001] This utility model belongs to the technical field of large circular knitting machine equipment, specifically relating to a side protection device for a large circular knitting machine. Background Technology

[0002] Circular knitting machines, also known as circular weft knitting machines (or circular weft knitting machines), have seen rapid development due to their numerous loop-forming systems (commonly referred to as yarn feed paths or loop formation paths, or simply paths), high speed, high output, rapid pattern changes, good fabric quality, fewer processing steps, and strong product adaptability.

[0003] The outer ring of the frame at the bottom of the large circular kiln is equipped with a protective frame to prevent personnel from entering while the machine is running. However, the protective frame is usually opened outwards. This method takes up a lot of opening space when opening to pick up materials. At the same time, the trolley will move backwards when opening, which is also quite troublesome. Utility Model Content

[0004] The present invention mainly addresses the technical problems existing in the prior art and provides a side protection device for a large circular knitting machine.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a side protection device for a large circular knitting machine, comprising multiple side frames arranged in a ring, a top mounting frame connected to the top of the multiple side frames, and a base frame provided at the bottom of the multiple side frames, characterized in that: a through storage cavity is opened at the bottom of each side frame, a first protective frame, a second protective frame and a third protective frame are respectively arranged between the storage cavities of the multiple side frames, the second protective frame is located on the outer ring of the first protective frame and the third protective frame, and the first protective frame and the second protective frame are slidably switched through the storage cavity of the side frame.

[0006] Preferably, the bottom sides of the first, second, and third protective frames are all equipped with casters, and the surfaces of the first, second, and third protective frames are all provided with multiple weight-reducing cavities.

[0007] Preferably, a first auxiliary roller frame is provided on each of the left and right sides of the storage cavity. The first auxiliary roller frame is located on the left and right sides of the side frame facing inward, and the surface of the first auxiliary roller frame is slidably connected to the first protective frame and the third protective frame.

[0008] Preferably, two adjacent side frames connecting the second protective frame are provided with second auxiliary roller frames on both sides, and the second auxiliary roller frames are respectively provided on the left and right sides of the second protective frame facing outward.

[0009] Preferably, the bottom of the side frame is provided with slots on the front and back sides corresponding to the storage cavity, and auxiliary rollers are rotatably arranged in the slots.

[0010] Preferably, the first protective frame, the second protective frame and the third protective frame are each provided with a side seat on one side of their bottom, and a pull rope is sleeved on the front side of the bottom of the side seat through a connecting shaft.

[0011] The beneficial effects of this utility model are as follows: By opening a storage cavity in the side frame, and setting a sliding first protective frame and a second protective frame between adjacent side frames, and setting universal wheels on both sides of the bottom of the first protective frame, the second protective frame, and the third protective frame of this device, they can slide and rotate to both sides, thereby reducing the opening space of the first protective frame and allowing the trolley to be pushed in immediately upon opening, increasing the working efficiency of the entire device. The second protective frame is located outside the first protective frame, so that the opening of the first protective frame does not affect the opening range of the second protective frame. At the same time, the side frame and pull rope set on the top of one side are used to limit the opening position of the protective frame. The pull rope is convenient for personnel to pull. At the same time, by setting a first auxiliary roller frame and a second auxiliary roller frame on both sides of the side frame, the first auxiliary roller frame provides an auxiliary sliding effect for the movement of the first and second protective frames, and the second auxiliary roller frame is used to assist the movement of the second protective frame. By opening slots on both sides of the bottom of the storage cavity and setting auxiliary rollers in the slots, they provide an auxiliary sliding effect for the bottom of the first, second, and third protective frames.

[0016] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0017] Example: A side protection device for a large circular knitting machine, such as... Figures 1-3As shown, the device includes multiple side frames arranged in a ring. A top mounting bracket is connected to the top of each side frame, and a base frame is provided at the bottom of each side frame. The device is characterized by a through-hole storage cavity at the bottom of each side frame. A first protective frame, a second protective frame, and a third protective frame are respectively arranged between the storage cavities of the multiple side frames. For the arrangement of the three side frames, two adjacent first and third protective frames are arranged as the inner ring, with their tops facing one side and pulling in opposite directions via side seats. Simultaneously, the second protective frame is arranged as the outer ring, allowing the first and third protective frames to be stored in the second protective frame regardless of their direction of movement, but only one can be moved at a time. The second protective frame is located on the outer ring of the first and third protective frames. The first and second protective frames slide and open through the storage cavities of the side frames. The function of the first, second, and third protective frames is to prevent external personnel from entering while the large circular knitting machine is in operation. No locking structure is required, as the large circular knitting machine is generally installed on flat ground, and the first, second, and third protective frames all have their own weight and will not open automatically without being pulled.

[0018] The first, second, and third protective frames are all equipped with casters on both sides of their bottom. The surfaces of the first, second, and third protective frames are also provided with multiple weight-reducing cavities. The casters make it easier to move the first, second, and third protective frames.

[0019] A first auxiliary roller frame is provided on both the left and right sides of the storage cavity. The first auxiliary roller frame is located on the left and right sides of the side frame facing inward. The surface of the first auxiliary roller frame is slidably connected to the first protective frame and the third protective frame. A second auxiliary roller frame is provided on both sides of the side frame of two adjacent connected second protective frames. The second auxiliary roller frames are respectively located on the left and right sides of the second protective frame facing outward.

[0020] The bottom of the side frame has slots on the front and back sides corresponding to the storage cavity. Auxiliary rollers are rotatably installed in the slots. The bottom of the first, second, and third protective frames each has a side seat on one side. A pull rope is connected to the front side of the bottom of the side seat through a connecting shaft. The auxiliary rollers allow the bottom sides of the first, second, and third protective frames to slide smoothly and avoid friction with the side frame. Side seats are provided on the opposite sides of the first and third protective frames so that the first and third protective frames are pulled in opposite directions when they move.

[0021] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and many variations are possible. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
