Description

Technical Field

[0001] The utility model relates to the field of sewing equipment, in particular to a telescopic bobbin core changing mechanism of sewing equipment. Background Art

[0002] The base of the sewing machine is equipped with a shuttle compartment, in which a bobbin case is installed. The bobbin with the bottom thread is installed in the bobbin case and cooperates with the machine needle to sew. Because industrial sewing machines usually work non-stop, and the amount of thread wound on the bobbin is very small, the bottom thread on the bobbin will run out every once in a while, so it is necessary to arrange a special person to watch and replace the bobbin with the bottom thread wound.

[0003] To this end, Chinese patent publication number CN220485990U discloses an automatic bobbin changing mechanism. However, when the mechanism is applied to some sewing equipment such as elastic band machine CN 212472479 U, interference may occur when feeding is required, and the conventional automatic bobbin changing mechanism cannot meet the demand.

[0007] The power source is a pneumatic cylinder or a hydraulic cylinder.

[0008] The sleeve is a linear bearing.

[0009] The sleeve is provided with a connecting plate, the outer wall of the fixing seat is provided with a penetrating mounting hole, the connecting plate is detachably connected to the outer wall of the fixing seat, and part of the sleeve passes through the mounting hole and is arranged in the fixing seat.

[0010] It also includes a mounting plate, on which the bobbin core changing mechanism is mounted, the driving rod is connected to the mounting plate, and the guide rod is connected to the mounting plate.

[0011] It also includes a buffer head, which is arranged opposite to the mounting plate.

[0012] The linear guide mechanisms are provided with two.

[0013] The beneficial effects of the utility model are as follows: the utility model provides a retractable shuttle core changing mechanism of a sewing device, which can be retracted and extended for use when shuttle changing is required, and can be retracted when not in use without occupying space.

[0018] The utility model is further described below in conjunction with the accompanying drawings: As shown in the figure, the retractable bobbin changing mechanism of the sewing equipment includes a fixed seat 1 and a bobbin changing assembly 2, and also includes a power source 3, which is arranged in the fixed seat and includes a driving rod 31, and the driving rod is extended to drive the bobbin changing assembly to reciprocate along a straight line; a linear guide mechanism 4, including a sleeve 41 and a guide rod 42, the sleeve is installed on the fixed seat, the guide rod is movably matched with the sleeve, and one end of the guide rod is connected to the bobbin changing assembly. The bobbin changing assembly can directly adopt the Chinese patent with announcement number CN220485990U, and the power source drives the bobbin changing assembly to move forward and backward to meet the use requirements, specifically, it is extended for use when the shuttle needs to be changed, and can be retracted when not in use without occupying space. The linear guide mechanism can adopt a linear bearing, or simply adopt a sleeve and a guide rod with sliding cooperation to share the gravity of the bobbin changing mechanism, so as to prevent the driving rod from being damaged due to excessive force.

[0019] In this embodiment, as shown in the figure, the power source is a pneumatic cylinder or a hydraulic cylinder.

[0020] In this embodiment, as shown in the figure, the sleeve is a linear bearing, which can reduce friction and is more convenient to use.
