Description

Technical Field

[0001] The utility model relates to the technical field of sewing machine driving, in particular to an industrial sewing machine driving device. Background Art

[0002] The driving motor on the sewing machine is used to provide power to drive the operation of the pulley. The power of the motor will vary depending on the purpose and working intensity of the sewing machine. Through gear transmission or belt transmission, etc., it is used to transmit the rotational motion of the motor to the main shaft of the sewing machine to realize the sewing action.

[0003] The above-mentioned and existing related technologies often have the following defects: when the sewing machine is running, the motor drives the belt on the pulley to rotate, drives the main shaft on the sewing machine to rotate, and drives the sewing machine to run normally. Since the belt in the pulley will wear out after long-term operation, it is necessary to replace it with a new belt to avoid malfunction during the operation of the sewing machine. The belt is sleeved on the inner wall of the pulley ruler ring, and it is inconvenient for the staff to disassemble and install the belt.

[0004] To this end, we propose an industrial sewing machine driving device. Utility Model Content

[0032] The specific settings and functions of the replacement device 4 and the auxiliary device 5 are described in detail below.

[0033] like Figure 2 and Figure 3 as well as Figure 4As shown, the replacement device 4 includes a rectangular groove 401, the rectangular groove 401 is opened on the surface of the pulley 2, the inner wall of the rectangular groove 401 is slidably connected with a paddle 402, the surface of the paddle 402 is fixedly connected with a fixing pin 403, the fixing pin 403 is slidably connected to the pulley 2, the arc surface of the fixing pin 403 is sleeved with a first spring 404, one end of the first spring 404 is fixedly connected to the pulley 2, the other end of the first spring 404 is fixedly connected to the paddle 402, the ruler tooth ring 3 The inner wall of the sewing machine is provided with a fixing groove 407, and the size of the fixing pin 403 is adapted to the size of the fixing groove 407. When the motor 1 is used to drive the sewing machine, the motor 1 drives the belt on the pulley 2, drives the main shaft on the sewing machine to operate, and drives the sewing machine to operate. When the belt on the pulley 2 needs to be replaced, the paddle 402 in the sliding rectangular groove 401 drives the fixing pin 403 to slide in the pulley 2. At this time, the first spring 404 is in a stretched state. When the fixing pin 403 falls off from the fixing groove 407, the ruler tooth ring 3 is removed. , remove the damaged belt, put a new belt on the pulley 2, then put the ruler ring 3 on the pulley 2 along the guide ring 406, remove the latch 408, the first spring 404 contracts, drives the fixing pin 403 to be inserted into the fixing groove 407, and fixes the ruler ring 3. The surface of the paddle 402 is fixedly connected with a positioning plate 410, and the surface of the positioning plate 410 is detachably mounted with a latch 408. The surface of the pulley 2 is provided with a positioning groove 409, and the size of the latch 408 is the same as that of the positioning groove 40 9 is adapted to the size of the belt pulley 2. The staff passes the pin 408 through the positioning plate 410 and inserts it into the positioning hole. The fixing pin 403 can be limited to facilitate the staff to replace the new belt. The surface of the ruler ring 3 is provided with a scale groove 405. The staff knows the position of the fixing groove 407 through the scale groove 405, which is convenient for aligning the fixing groove 407 with the position of the fixing pin 403. The surface of the pulley 2 is fixedly connected with a guide ring 406. The guide ring 406 facilitates the staff to put the ruler ring 3 on the pulley 2 for installation.

[0034] like Figure 5 and Figure 6As shown, the auxiliary device 5 includes a fixed bracket 51, and the fixed bracket 51 is fixedly connected to the motor 1. A second spring 55 is fixedly connected to the surface of the fixed bracket 51. The other end of the second spring 55 is fixedly connected to a limiting block 56. The inner wall of the limiting block 56 is rotatably connected to a driven pulley 57. The belt on the pulley 2 will wear after long-term operation, resulting in the pulley 2 and the belt not fitting together, which can easily lead to reduced transmission efficiency. When the belt is simultaneously sleeved on the driven wheel 57 in the limiting block 56, the second spring 55 will stretch and hold the belt apart. As the belt wears, the second spring 55 gradually stretches to support the belt, so that the belt fits the pulley 2. The surface of the fixed bracket 51 is fixedly connected to a support rod 52. The inner wall of the support rod 52 is threadedly connected with a screw rod 54, and a circular groove 58 is formed on the surface of the limit block 56. The size of the circular groove 58 is matched with the size of the screw rod 54. When replacing the belt, the limit block 56 is moved until the telescopic rod 53 is fully retracted. At this time, the second spring 55 is in a compressed state. The staff rotates the screw rod 54, and the screw rod 54 will be inserted into the circular groove 58 to limit the limit block 56, which is convenient for replacing and installing a new belt. The surface of the fixed bracket 51 is fixedly connected with the telescopic rod 53, and the other end of the telescopic rod 53 is fixedly connected to the limit block 56.

[0035] Working principle: When the motor 1 is used to drive the sewing machine, the motor 1 drives the belt on the pulley 2, drives the main shaft on the sewing machine to operate, and drives the sewing machine to operate. When the belt on the pulley 2 needs to be replaced, the paddle 402 in the sliding rectangular groove 401 drives the fixing pin 403 to slide in the pulley 2. At this time, the first spring 404 is in a stretched state. When the fixing pin 403 falls off from the fixing groove 407, the staff will pass the pin 408 through the positioning plate 410 and insert it into the positioning hole. The fixing pin 403 can be limited, which is convenient for the staff to replace the new belt, remove the ruler ring 3, remove the broken belt, put the new belt on the pulley 2, and then put the ruler ring 3 along the guide ring 406 on the pulley. 2, the guide ring 406 is convenient for the staff to put the ruler tooth ring 3 on the pulley 2 for installation. The staff knows the position of the fixing groove 407 through the scale groove 405, and conveniently aligns the fixing groove 407 with the position of the fixing pin 403, removes the latch pin 408, and the first spring 404 contracts to drive the fixing pin 403 to be inserted into the fixing groove 407, and fixes the ruler tooth ring 3. By setting the replacement device 4, when replacing the belt of the pulley 2, the staff removes the ruler tooth ring 3 by pulling the fixing pin 403, and quickly replaces the belt on the pulley 2. The fixing pin 403 is fixed by the contraction of the spring, and the ruler tooth ring 3 can be fixed, which is convenient for the staff to replace the belt on the pulley 2.

[0036] After long-term operation, the belt on the pulley 2 will wear out, causing the pulley 2 to not fit the belt, which can easily lead to reduced transmission efficiency. When the belt is simultaneously sleeved on the driven wheel 57 in the limit block 56, the second spring 55 will stretch and hold the belt open, and the telescopic rod 53 will expand and contract with the expansion and contraction of the second spring 55, so as to limit the spring and the limit block 56 to prevent the driven wheel 57 in the limit block 56 from derailing from the belt. As the belt wears, the second spring 55 gradually stretches to support the belt, making the belt fit the pulley 2. When changing the belt, the limit block 56 is moved until the telescopic rod 53 is fully retracted. At this time, the second spring 55 is in a compressed state, and the staff rotates the screw rod 54, which will be inserted into the circular groove 58 to limit the limit block 56, making it convenient to replace and install a new belt. By setting the auxiliary device 5, after the belt has been used for a long time, the worn belt is stretched by the second spring 55, driving the driven wheel 57 to stretch the belt, so that the belt and the pulley 2 are more closely fitted, which effectively improves the utilization rate of the belt and improves the transmission efficiency of the pulley 2 to a certain extent.
