[0001] The utility model relates to the field of cam opening mechanisms, in particular to a cam opening mechanism for a core loom. Background Art

[0002] A loom is also called a weaving machine, a textile machine, a cotton textile machine, etc. It can be divided into cotton textile machines, wool textile machines, sack looms, and silk looms according to the classification of fabric fibers. The opening mechanism is one of the five major mechanisms of a loom and is an important mechanism necessary for the formation of fabrics. Its task is to divide the warp yarns inserted into each page of the heald frame into two layers, upper and lower, to form a shed according to the requirements of the fabric organization, and to close the shed after the weft yarns are introduced to form a woven fabric of warp and weft yarns. The opening mechanism is its important component.

[0003] However, the cam opening mechanism in the existing market has a poor shock absorption effect during use. The loom will vibrate when working. The long-term vibration of the opening mechanism will cause the internal parts to loosen, and it is inconvenient to add lubricating oil.

[0004] Therefore, it is necessary to provide a cam opening mechanism for a core loom to solve the above-mentioned technical problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A structural schematic diagram of a preferred embodiment of a cam opening mechanism for a core loom provided by the utility model; Figure 2 for Figure 1 The schematic diagram of the telescopic sleeve installation structure is shown; Figure 3 for Figure 1 A schematic diagram of the first spring installation structure is shown; Figure 4 for Figure 1 The second spring installation structure schematic diagram shown is a cam opening mechanism for a core loom, comprising: a base 1, a protective shell 2 is slidably installed inside the base 1, the outer surface of the protective shell 2 fits with the inner surface of the base 1, telescopic sleeves 3 are fixedly installed at the four corners of the base 1, and the number of telescopic sleeves 3 is four, telescopic rods 4 are slidably installed inside the four telescopic sleeves 3, sealing pads 5 are fixedly installed at the bottom ends of the four telescopic rods 4 and inside the telescopic sleeves 3, the outer surface of the sealing pad 5 fits with the inner surface of the telescopic sleeve 3, the bottom of the four telescopic sleeves 3 is fixedly installed with a first spring 6, and the four telescopic sleeves 3 have a plurality of springs. There are air holes 7 on the outside, and there are multiple air holes 7. The loom will vibrate when it is working. Long-term vibration of the opening mechanism will cause its internal parts to loosen. When the protective shell 2 vibrates, the protective shell 2 moves back and forth up and down inside the base 1, and the telescopic rod 4 moves back and forth up and down inside the telescopic sleeve 3. During this process, the first spring 6 is continuously compressed and reset, which effectively buffers the vibration and protects the opening mechanism. Due to the setting of the sealing gasket 5, the air inside the telescopic sleeve 3 can only be discharged or entered through the air holes 7, thereby providing damping, thereby avoiding the situation where the first spring 6 makes it difficult to stop the telescopic rod 4 from moving back and forth up and down.

[0021] A transmission shaft 8 is rotatably installed inside the protective shell 2 through a bearing. A cam body 9 is connected to an equidistant keyway on the outside of the transmission shaft 8, and there are multiple cam bodies 9. One end of the transmission shaft 8 passes through the protective shell 2 and extends to the outside. A motor 10 fixedly installed on the protective shell 2 is connected to a keyway at one end of the transmission shaft 8. The cam body 9 is connected to a connecting rod. The transmission shaft 8 is driven to rotate by the operation of the motor 10, and the transmission shaft 8 drives the cam body 9 to rotate, thereby changing the angle of the connecting rod.

[0022] A top cover 11 is fixedly installed on the top of the protective shell 2 by screws, and an oil filling pipe 12 is fixedly installed at the top center point of the top cover 11. A fixing ring 13 is fixedly installed inside the oil filling pipe 12, and a second spring 14 is placed above the fixing ring 13. An oil filling cap 16 is mounted on the top of the oil filling pipe 12, and a steel ball 15 is placed on the top of the second spring 14 and below the oil filling cap 16. Due to the reciprocating up and down movement of the loom opening mechanism, the consumption of lubricating oil is large. If the lubricating oil is not added in time, it will cause dry grinding and rapid damage to the parts. The oil pot is aligned with the steel ball 15 and moved downward. The downward movement of the steel ball 15 compresses the second spring 14. At this time, lubricating oil is added, and the lubricating oil enters the interior of the protective shell 2 through the oil filling pipe 12 to lubricate the internal parts. After adding, the oil pot is moved up. Due to the reset effect of the second spring 14, the steel ball 15 moves upward to block the oil filling cap 16 to prevent the entry of dust and impurities. It has the function of facilitating the addition of lubricating oil and improves practicality.

[0023] The working principle of the cam opening mechanism of a core loom provided by the utility model is as follows:

[0024] The first step: the loom will vibrate when it is working, and the long-term vibration of the opening mechanism will cause its internal parts to loosen. When the protective shell 2 vibrates, the protective shell 2 moves back and forth up and down inside the base 1, and the telescopic rod 4 moves back and forth up and down inside the telescopic sleeve 3. During this process, the first spring 6 is continuously compressed and reset, which effectively buffers the vibration and protects the opening mechanism. Due to the setting of the sealing gasket 5, the air inside the telescopic sleeve 3 can only be discharged or entered through the air hole 7, thereby providing damping, thereby preventing the first spring 6 from making it difficult to stop the telescopic rod 4 from moving back and forth up and down.

[0025] Step 2: Due to the reciprocating up and down movement of the loom opening mechanism, the consumption of lubricating oil is relatively large. If the lubricating oil is not added in time, it will cause dry grinding of parts and rapid damage. Aim the oil pot at the steel ball 15 and move it downward. The steel ball 15 moves downward to compress the second spring 14. At this time, add lubricating oil. The lubricating oil enters the interior of the protective shell 2 through the oil filling pipe 12 to lubricate the internal parts. After adding, move the oil pot upward. Due to the reset effect of the second spring 14, the steel ball 15 moves upward to block the oil filling cap 16 to prevent the entry of dust and impurities. It has the function of facilitating the addition of lubricating oil and improves practicality.

[0026] Compared with the related art, the cam opening mechanism of a core loom provided by the utility model has the following beneficial effects:

[0027] The loom will vibrate when working, and the long-term vibration of the opening mechanism will cause its internal parts to loosen. When the protective shell 2 vibrates, the protective shell 2 moves back and forth up and down inside the base 1, and the telescopic rod 4 moves back and forth up and down inside the telescopic sleeve 3. During this process, the first spring 6 is continuously compressed and reset, which effectively buffers the vibration and protects the opening mechanism. Due to the setting of the sealing gasket 5, the air inside the telescopic sleeve 3 can only be discharged or entered through the air hole 7, thereby providing damping, thereby avoiding the situation where the first spring 6 makes it difficult to stop the telescopic rod 4 from moving back and forth up and down.
