Description

Technical Field

[0001] This utility model relates to the field of circular knitting machine technology, and in particular to a detachable cauldron structure for a circular knitting machine. Background Technology

[0002] Circular knitting machines, also known as circular weft knitting machines, have seen rapid development due to their numerous loop-forming systems, high speed, high output, rapid pattern changes, good fabric quality, fewer processes, and strong product adaptability.

[0003] Existing circular knitting machines require the knitting cauldron and the machine frame's worktable to be as parallel as possible during operation, and the sleeves to be as coaxial as possible with the cauldron. For example... Figure 1 The diagram shows the existing installation structure of a large circular knitting machine, including a frame 1', a large cauldron 2' mounted on the frame 1', and a central support 3' connecting the cauldron 2' and the frame 1'. The cauldron 2' and the central support 3' are connected by bolts, and a sleeve 4' is also fitted onto the cauldron 2'. During installation, the cauldron 2' is placed on the sleeve 4', and then locked onto the central support 3'. After this assembly, it is difficult to ensure the coaxiality and parallelism between the cauldron and the sleeve, thus requiring fine-tuning by workers. Fine-tuning is typically done manually by striking the cauldron with a hammer. While this meets the adjustment requirements, hammering is inefficient, wastes manpower, is difficult for workers to operate, and can easily damage components, reducing their lifespan. To solve this problem, this utility model was developed. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model proposes a separate large tripod structure for a circular knitting machine that is simple in structure and easy to adjust.

[0005] To achieve the above objectives, the technical solution of this utility model is to provide a separate cauldron structure for a circular knitting machine, including a frame, a central support foot set on the frame, and a sleeve set on the frame. The central support foot is provided with a cauldron. The feature is that it also includes a sleeve seat, which is sleeved on the sleeve. An adjustment device for adjusting the coaxiality and parallelism between the cauldron and the sleeve is provided between the sleeve seat and the cauldron.

[0006] A further improvement is that the adjustment device is: a coaxiality adjustment device is provided between the sleeve base and the cauldron for adjusting the coaxiality between the cauldron and the sleeve, and a parallelism adjustment device is provided between the sleeve base and the cauldron for adjusting the parallelism between the cauldron and the sleeve.

[0007] A further improvement is that the coaxiality adjustment device includes several lateral adjustment bolts, the large cauldron is provided with a connecting sleeve, the connecting sleeve is fitted onto the sleeve seat, the lateral adjustment bolts are threaded through the sleeve seat, and the lateral adjustment bolts resist the sleeve seat.

[0008] A further improvement is that the parallelism adjustment device includes a connecting plate, which is disposed on the sleeve seat. The cauldron has a receiving interface, and the cauldron is sleeved on the sleeve seat with the connecting plate located at the cross section of the receiving interface and resisting each other. The cauldron is provided with a pushing device for pushing against the connecting plate.

[0009] A further improvement is that the supporting device includes several longitudinal adjusting bolts, which are threadedly connected to the cauldron and located at the bearing interface, and the longitudinal adjusting bolts resist the connecting plate.

[0010] The advantages and beneficial effects of this utility model are as follows:

[0011] The structure is simple and easy to adjust. The cauldron and sleeve are connected by a sleeve base, transforming the adjustment of their coaxiality and parallelism from a simple adjustment of the cauldron and sleeve base to an adjustment of the cauldron and sleeve base itself. Then, horizontal and vertical bolts are used for pre-tightening to abut against the sleeve base and the connecting plate on it. This eliminates the traditional method of using a hand-held hammer, not only making it easier for workers to adjust the sleeve and improving efficiency, but also protecting all components and extending their service life.

[0014] Figure 3 This is an enlarged structural diagram of point A in this utility model; Detailed Implementation

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0016] like Figures 2-3As shown, a split-type cauldron structure for a circular knitting machine includes a frame 1, a central support leg 3 mounted on the frame 1, a sleeve 4 mounted on the frame 1, and a sleeve seat 5. A cauldron 2 is mounted on the central support leg 3, and the sleeve seat 5 is fitted onto the sleeve 4. A coaxiality adjustment device for adjusting the coaxiality between the cauldron 2 and the sleeve 4 is provided between the sleeve seat 5 and the cauldron 2, and a parallelism adjustment device for adjusting the parallelism between the cauldron 2 and the sleeve 4 is provided between the sleeve seat 5 and the cauldron 2.

[0017] Specifically, the coaxiality adjustment device includes multiple lateral adjustment bolts 7, the large cauldron 2 is provided with a connecting sleeve 6, the connecting sleeve 6 is sleeved on the sleeve seat 5, the lateral adjustment bolts 7 are threaded in an array and pass through the sleeve seat 5, and the lateral adjustment bolts 7 resist the sleeve seat 5.

[0018] Specifically, the parallelism adjustment device includes a connecting plate 8, which is disposed on the sleeve seat 5. The large cauldron 2 has a bearing interface, which is sleeved on the sleeve seat 5 and the connecting plate 8 is located at the cross section of the bearing interface and resists each other. The large cauldron 2 is provided with a plurality of longitudinal adjusting bolts 9 for supporting the connecting plate 8. The longitudinal adjusting bolts 9 are threaded and arranged in a ring array on the large cauldron 2 and located at the bearing interface. The longitudinal adjusting bolts 9 resist the connecting plate 8.

[0019] Working principle:

[0020] During installation, the sleeve seat 5 is placed on the sleeve 4, and then the sleeve seat 5 is placed on the large cauldron 2, ensuring that the connecting plate 8 on the sleeve seat 5 is located within the receiving interface. The operator then makes minor adjustments to the coaxiality and parallelism between the sleeve seat 5 and the large cauldron 2. For coaxiality adjustments, the lateral adjusting bolt 7 is rotated, causing it to abut against the sleeve seat 5, thus adjusting the concentricity of the large cauldron 2 and the sleeve seat 5, i.e., adjusting the concentricity of the large cauldron 2 and the sleeve 4. For parallelism adjustments, the longitudinal adjusting bolt 9 is rotated, causing it to resist the connecting plate 8, thus adjusting the parallelism of the large cauldron 2 and the sleeve seat 5, i.e., adjusting the parallelism of the large cauldron 2 and the sleeve 4.

[0021] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions above are only illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
