Description

Technical Field

[0001] The invention relates to the technical field of weaving, and in particular to an arrangement method of linear motors on a dobby loom. Background Art

[0002] In the weaving process, an opening mechanism is required. The common opening mechanism currently has a set of output rods rotating around an axis, each of which is connected to the heald frame of the loom through a corresponding connecting rod structure. The linear motor uses a cam or other eccentric transmission mechanism to make the output rods swing alternately, and the connecting rod structure drives the corresponding heald frame to move vertically up and down, and the heald frame drives the warp yarn to move up and down to achieve various opening actions. The opening mechanism is driven by a motor, and the movement of each output rod can be independently controlled, which is easy to realize electronic control and realize that each heald frame controls the flower plate according to demand.

[0003] Chinese invention application CN202210095381.0 discloses an opening mechanism, which realizes the application of linear motors in the opening mechanism, and reduces the space occupied by the linear motors in the thickness direction by designing the layout structure of the two linear motors in the same group, so that the gap between the two adjacent loom heald frames can be smaller, while providing sufficient motor power under the premise of meeting the installation requirements. However, due to the unreasonable layout structure of the linear motors, in order to enable the two adjacent groups of linear motors to operate normally, one of the groups must use a long connecting piece for power transmission. Compared with the linear motor that uses a short connecting piece for power transmission, the linear motor that uses a long connecting piece for power transmission has too long torque when driving the loom heald frame to move up and down, and the power consumption increases almost linearly, resulting in problems of excessive energy consumption and high production costs. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a method for arranging linear motors on a loom dobby.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows: A method for arranging linear motors on a loom dobby comprises a plurality of linear motors mounted on a loom frame, wherein the output shafts of the plurality of linear motors are connected one by one with a plurality of loom heald frames through a connecting rod structure, and the plurality of linear motors are arranged in two rows, and correspond to the two sides of the top of the loom heald frames respectively; in the plurality of linear motors in each row, every four linear motors are divided into a linear motor group along the arrangement direction of the plurality of loom heald frames, and the four linear motors are paired to form a linear motor pair, and the two linear motor pairs are arranged alternately from left to right, and the pitch of four loom heald frames is spaced between two adjacent linear motor groups. When the linear motor groups in one row are arranged on the plurality of loom heald frames, the linear motor groups in the other row are spaced by the pitch of four loom heald frames between the two adjacent linear motor groups, and the linear motor groups in the previous row are also spaced by the pitch of four loom heald frames between the two adjacent linear motor groups. Along the arrangement direction of the plurality of loom heald frames, this arrangement structure can ensure that the operations of the two adjacent linear motor groups will not affect each other.

[0006] Preferably, along the arrangement direction of the multi-piece loom heald frames, there is a spacing between two linear motor pairs and between two linear motors used to form a linear motor pair, and the spacing is adjustable, thereby allowing the gap between two adjacent loom heald frames to be adjustable, so that the opening mechanism can adapt to the needs of various fabric weaving production. Specifically, the linear motor is connected to the loom frame through a connecting structure. Preferably, along the arrangement direction of the multi-piece loom heald frames, the connecting structure includes two adjustment slots spaced apart on the loom frame, and the housing of the linear motor has a positioning hole that cooperates with the adjustment slot, and the positioning hole and the adjustment slot are locked into a whole by bolts.

[0007] Compared with the prior art, the present invention has the following beneficial effects: Based on the existing opening mechanism driven by linear motors, the present invention optimizes the arrangement and layout of the linear motors so that each linear motor has the same torque when driving the heald frame of the loom to move up and down, eliminating the need for long connecting pieces for power transmission, thereby reducing energy consumption.

[0010] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention. Example 1

[0011] A method for arranging linear motors on a loom dobby, such as Figure 1 As shown, it includes multiple linear motors 1 assembled on the loom frame, and the output shafts of the multiple linear motors 1 are connected one by one with multiple loom heald frames 3 through a connecting rod structure 2. During implementation, the linear motor 1 drives the loom heald frame 3 to move up and down by driving the connecting rod structure 2.

[0012] The arrangement diagram of multiple linear motors 1 is shown in FIG. Figure 2 As shown, a plurality of linear motors 1 are arranged in two rows, and correspond to the two sides of the top of the loom heald frame 3 respectively. Specifically, in each row of the plurality of linear motors 1, every four linear motors 1 are divided into a linear motor group A along the arrangement direction of the multiple loom heald frames 3. The four linear motors 1 are paired to form a linear motor pair a, and the two linear motor pairs a are arranged alternately from left to right, so that the two adjacent linear motor pairs a will not affect each other during operation. At the same time, the two adjacent linear motor groups A are spaced by a pitch B of four loom heald frames 3. In specific implementation, when the linear motor group A in one of the rows is arranged on the multiple loom heald frames 3, Two adjacent linear motor groups A are spaced at a pitch B of four loom heald frames 3 to assemble the linear motor group A in another row, and two adjacent linear motor groups A are also spaced at a pitch B of four loom heald frames 3 to assemble the linear motor group A in the previous row. Along the arrangement direction of the multiple loom heald frames 3, this arrangement structure can ensure that the operations of the two adjacent linear motor groups A will not affect each other, so that the torque of each linear motor 11 when driving the loom heald frame 3 to move up and down can be the same, and there is no need to rely on long connecting plates for power transmission, thereby achieving the purpose of reducing energy consumption and reducing production costs.

[0013] As a preferred solution of the above embodiment, along the arrangement direction of the multi-piece loom heald frames 3, there is a spacing between the two linear motor pairs a, and between the two linear motors 1 used to form the linear motor pair a, and the spacing is adjustable, thereby allowing the gap between two adjacent loom heald frames 3 to be adjustable, so that the opening mechanism can adapt to the needs of various fabric weaving production, specifically, as Figure 3As shown, the linear motor 1 is connected to the loom frame via a connecting structure 4. Preferably, along the arrangement direction of the multi-piece loom heald frames 3, the connecting structure 4 includes two adjustment slots 41 spaced apart on the loom frame, and the housing of the linear motor 1 has a positioning hole 42 that cooperates with the adjustment slot 41, and the positioning hole 42 and the adjustment slot 41 are locked into a whole by bolts 43.
