Description

Technical Field

[0001] The utility model relates to the field of thread twisting, and particularly relates to a thread twisting bobbin assembly. Background Art

[0002] The twisting bobbin is a device used in the textile industry, mainly used for winding and storing twisted yarn. The twisting bobbin is usually made of metal material, plastic material or steel paper material. Different materials have different durability and strength. In the actual use of the twisting bobbin, there are the following shortcomings: the existing yarn bobbin has a fixed length, so the winding length of the bobbin is also fixed. When the equipment is replaced with a longer yarn due to production needs, the original single yarn cannot be completely collected. The bobbin needs to disconnect the yarn and rewind it on the new twisting bobbin, resulting in low production efficiency; and the existing bobbin has no external protection after winding the yarn, and the yarn is easily scratched by foreign objects or contaminated by dirt.

[0003] In summary, in order to solve the deficiencies in the prior art, a twisting bobbin assembly with a simple structure needs to be designed. Utility Model Content

[0004] The utility model provides a twisting bobbin component to solve the problems of the prior art.

[0005] The purpose of the utility model can be achieved through the following technical scheme: a twisting bobbin assembly comprises: an outer cylinder, an inner cylinder, a left baffle, a right baffle and a sleeve, the left baffle is fixed to the left side of the inner cylinder, the right baffle is fixed to the right side of the outer cylinder and is provided with a through hole, a sliding limit strip and a clamping block are provided inside the outer cylinder, the clamping block is located on the left side of the sliding limit strip and is disconnected, a sliding groove matching the sliding limit strip is provided on the inner cylinder, a snap ring groove connected to the sliding groove and vertically arranged is provided on the right side of the inner cylinder, the clamping block matches the snap ring groove arrangement, and the sleeve is slidably sleeved on the outside of the outer cylinder and the inner cylinder.

[0006] As a further improvement, the sleeve comprises an outer sleeve and an inner sleeve, and the inner sleeve is slidably mounted in the outer sleeve.

[0007] As a further improvement, winding friction grooves are provided on the end surfaces of the outer cylinder and the inner cylinder at intervals.

[0008] As a further improvement, an arc-shaped guide portion is provided on the left side of the outer cylinder.

[0009] As a further improvement, the sliding limit strips and the sliding grooves are arranged in four groups at annular intervals.

[0010] Compared with the prior art, the twisting bobbin assembly of the utility model has the following beneficial effects:

[0011] Through the cooperation of the inner cylinder and the outer cylinder, the design of the sliding limit strip and the sliding groove makes it impossible for the inner cylinder to rotate relative to the outer cylinder, thereby improving the overall stability; the inner cylinder can be pulled out from the outer cylinder to extend the length of the winding, making it simple and efficient to adjust the winding length; when the inner cylinder is pulled to the specified position, the clamping block of the outer cylinder can enter the clamping ring groove of the inner cylinder, and the inner cylinder is rotated to a certain angle by applying a certain force to overcome the friction resistance, thereby locking the position of the inner cylinder, preventing the inner cylinder from slipping out, and ensuring the safety of the winding process; after the winding is completed, the sleeve can block the outer cylinder and the inner cylinder to prevent foreign objects from scratching the yarn or being contaminated by dirt, which helps to maintain the cleanliness and quality of the yarn.
