AI Technical Summary
Conventional dual-system flat knitting machines require two stepper motors, which take up a lot of space, cannot meet the needs of limited installation space, and are inconvenient to maintain.
Two stepper motors are combined into one to form a stacked structure. A hollow shaft and independently controlled rotor design enable co- or counter-rotation. Side mounting is used to save space and facilitate maintenance.
It reduces installation space requirements, lowers maintenance costs, and improves installation efficiency and maintenance convenience.

Abstract
Description
Technical Field
[0001] The utility model discloses a stepping motor with a dual-system flat knitting machine structure, belonging to the technical field of stepping motors. Background Art
[0002] Currently, conventional dual-system flat knitting machines on the market all use two stepper motors. There is a stator and a rotor between the two end covers, and there is only one output shaft. The motor can only rotate in one direction. Dual-system flat knitting machines need to operate in two directions simultaneously, and can only use two stepper motors. For occasions with small installation space, it cannot meet customer needs. Utility Model Content
[0003] In order to overcome the above problems, the utility model discloses a stepper motor with a dual-system flat knitting machine structure. The two stepper motors are combined into one motor to form a superimposed structure, which reduces space waste, saves resources, and reduces subsequent maintenance costs.
[0004] The technical solution of the utility model is as follows:
[0005] A stepping motor with a dual-system flat knitting machine structure, comprising:
[0006] End cover, the end cover includes a left end cover, a middle end cover and a right end cover, the motor assembly 1 is mounted between the left end cover and the middle end cover, and the motor assembly 2 is mounted between the middle end cover and the right end cover;
[0007] a first rotating shaft, disposed on the left side of the end cover and constituting a portion of the first motor assembly, wherein the first rotating shaft is a hollow rotating shaft having openings on both sides, and a left end thereof extending out of the left side of the left end cover;
[0008] The second rotating shaft is arranged on the right side of the end cover and constitutes a part of the motor component 2, wherein the left end of the second rotating shaft enters from the right opening of the first rotating shaft, passes through the entire first rotating shaft, and extends from the left opening of the first rotating shaft, and the right end of the second rotating shaft extends out of the right side of the right end cover.
[0009] Preferably, the diameter of the portion of the left side of the second rotating shaft extending into the first rotating shaft is smaller than the diameter of the portion on the right side thereof, and the two are connected via a frustum.
[0010] Preferably, the motor assembly 1 and the motor assembly 2 are independently controlled so that the rotating shaft 1 and the rotating shaft 2 can independently rotate in the same direction or in opposite directions.
[0011] Preferably, the design of the end cover allows it to be installed on a dual-system flat knitting machine in a side-mounted manner, so as to save installation space and facilitate subsequent maintenance.
[0012] The beneficial effects of the utility model are:
[0013] This new structure incorporates two stators and two rotors. The left shaft is hollow, while the right shaft passes through the center, creating two stacked stepper motors. The two motor shafts can rotate in either direction, reducing installation space while eliminating an end cap and saving resources. The dual-system knitting machine has a limited installation space, and the installation method has been changed from flat-surface front cover installation to side-surface front cover installation. Flat-surface front cover installation requires the removal of the load component, leaving no room for axial operation. Side-surface front cover installation allows for direct removal of the motor for replacement and maintenance, facilitating subsequent system maintenance and significantly reducing maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION
[0015] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.
[0016] like Figure 1 As shown, a stepping motor with a dual-system flat knitting machine structure includes:
[0017] End cover 1, which includes a left end cover 1-1, a middle end cover 1-2 and a right end cover 1-3. Motor assembly 1 is installed between the left end cover 1-1 and the middle end cover 1-2, and motor assembly 2 is installed between the middle end cover 1-2 and the right end cover 1-3;
[0018] A rotating shaft 2 is provided on the left side of the end cover 1 and constitutes a part of the motor assembly 1, wherein the rotating shaft 2 is a hollow rotating shaft with openings on both sides, and its left end extends out of the left side of the left end cover 1-1;
[0019] The rotating shaft 2 3 is arranged on the right side of the end cover 1 and constitutes a part of the motor assembly 2, wherein the left end of the rotating shaft 2 3 enters from the right opening of the rotating shaft 1 2, passes through the entire rotating shaft 1 2, and extends from the left opening of the rotating shaft 1 2, and the right end of the rotating shaft 2 3 extends out of the right side of the right end cover 1-3.
[0020] Preferably, the diameter of the portion of the left side of the second rotating shaft 3 extending into the first rotating shaft 2 is smaller than the diameter of the portion on the right side thereof, and the two are connected via a frustum.
[0021] Preferably, the motor assembly 1 and the motor assembly 2 are independently controlled so that the rotating shaft 1 2 and the rotating shaft 2 3 can independently rotate in the same direction or in opposite directions.
[0022] Preferably, the design of the end cover 1 allows it to be installed on a dual-system flat knitting machine in a side-mounted manner, so as to save installation space and facilitate subsequent maintenance.
