Description

Technical Field

[0001] The utility model relates to the technical field related to jacquard machine transmission, in particular to a servo control device for synchronous control of a jacquard machine. Background Art

[0002] The jacquard machine has a relatively low jacquard shaft speed requirement. Therefore, the corresponding reduction structure is often required in the servo control structure of the jacquard machine. The most common method is to independently install a reducer between the jacquard machine and the servo motor to achieve the deceleration and torque increase of the servo motor. However, the setting of an independent reducer often makes the overall equipment bloated and the cost will be greatly increased.

[0003] Based on this, we hope to obtain a method with the same deceleration effect and lower cost, so we consider the form of belt transmission. After studying the existing jacquard machines and related literature, we found that there are jacquard machines that use belt transmission to achieve servo control, but there are often the following problems during control: first, the belt transmission will be unstable during long-term use, and the belt will become loose and affect the transmission; second, it is more laborious to adjust the transmission ratio of the belt, and the pulley and belt often need to be replaced at the same time, which is cumbersome.

DETAILED DESCRIPTION

[0024] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in conjunction with the embodiments below. It should be understood that the following text is only used to describe a servo control device for synchronous control of a jacquard machine or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model. As used in this article, the terms up and down and left and right are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors. The specific features of the servo control device for synchronous control of a jacquard machine are described in detail below:

[0025] Reference Figure 1-Figure 4 According to an embodiment of the utility model, a servo control device for synchronous control of a jacquard machine includes a base 10, on which a No. 1 mounting seat 11 and a pair of No. 2 mounting seats 17 are fixedly mounted, a jacquard shaft 15 is rotatably mounted between the No. 2 mounting seats 17, a No. 1 pulley 16 is fixed at one end of the jacquard shaft 15, a servo motor 13 is fixedly mounted on the No. 1 mounting seat 11, a motor shaft of the servo motor 13 passes through the No. 1 mounting seat 11 and is fixed with a No. 2 pulley 12, a belt 14 is installed between the No. 2 pulley 12 and the No. 1 pulley 16, because the rotation speed of the servo motor 13 is too high relative to the rotation speed of the jacquard shaft 15, the above-mentioned belt transmission form is adopted, and the transmission ratio of the No. 2 pulley 12 to the No. 1 pulley 16 is adjusted to achieve speed control, so that the rotation speed of the jacquard shaft 15 can be adjusted.

[0026] However, in actual use, the belt drive form will face the following two problems:

[0027] Problem 1: The belt drive will become loose after long-term use, resulting in poor transmission effect;

[0028] Question 2: There is a situation where the rotation speed of the jacquard shaft 15 needs to be changed, specifically, the second pulley 12 or the first pulley 16 needs to be replaced.

[0029] Therefore, based on the above two problems, a tensioning mechanism 40 is installed between the No. 1 mounting seat 11 and the No. 2 mounting seat 17. The tensioning mechanism 40 includes a tensioning wheel 22 and a lifting control component that can control the lifting of the tensioning wheel 22. The tensioning wheel 22 abuts against the belt 14. When the above two problems occur, the lifting control component keeps the belt 14 in a tensioned state at all times. Preferably, for the convenience of user operation and to have a certain self-locking function, a screw lifting structure is adopted. Specifically, the lifting control component includes a support seat 20 fixedly installed on the base 10, a slider 24 is slidably arranged in the support seat 20, the tensioning wheel 22 is rotatably arranged on the slider 24, a threaded shaft 21 is provided through the slider 24 and the support seat 20, the threaded shaft 21 is rotatably connected to the support seat 20 and the threaded shaft 21 is threadedly connected to the slider 24, and a handle 26 is installed at the end of the threaded shaft 21; the threaded shaft 21 is driven to rotate by rotating the handle 26, and the slider 24 is driven to rise and fall by the threaded connection between the threaded shaft 21 and the slider 24, and finally the tensioning wheel 22 on the slider 24 can be driven to rise and fall.

[0030] During use, the handle 26 may be accidentally touched. Based on this problem, the handle 26 and the threaded shaft 21 are deliberately made into a detachable structure. Specifically, one end of the threaded shaft 21 is fixedly connected to a pin 29, and a sleeve 25 is fixedly connected to the handle 26. A slot 30 matching the pin 29 is provided on the sleeve 25. By inserting the pin 29 into the slot 30, the handle 26 and the threaded shaft 21 can be relatively locked (they cannot rotate with each other).

[0031] Preferably, in order to facilitate the placement of the handle 26 after disassembly, at least one hole 27 is opened on the handle 26, and a hook 28 is fixedly installed on the support base 20, and the handle 26 is hung on the hook 28 through the hole 27 to realize the daily placement of the handle 26.

[0032] In order to increase the overall stability, a guide wheel 18 is rotatably mounted on the support seat 20 , and the guide wheel 18 abuts against the belt 14 , thereby ensuring the stability of the belt 14 .

[0033] Furthermore, in order to prevent the belt 14 from accidentally falling off during adjustment, a No. 1 shell 23 fixed to the slider 24 is provided on the outer sleeve of the tensioning wheel 22, and a No. 2 shell 19 fixed to the support seat 20 is provided on the outer sleeve of the guide wheel 18. Both the No. 2 shell 19 and the No. 1 shell 23 play a certain role in limiting and preventing the belt 14 from falling off.

[0034] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
