However, during its long-term operation, due to the continuous friction between mechanical components, it is easy to cause increased wear, affecting the normal operation and service life of the equipment. To solve this problem, it is often necessary to spray lubricating oil on the parts of the single-sided jacquard weft knitting machine to achieve lubrication and reduce wear. However, the traditional single-sided jacquard weft knitting machine has certain deficiencies in lubrication.

[0003] After retrieval, Chinese Patent Publication No.: CN208472308U discloses an oil spraying device for a single-sided jacquard weft knitting machine, including a lower needle cylinder, a saddle, jacquard blades, an oil and gas spray pipe, a return triangle and a base. A support seat is connected to the top of the base, the support seat is rotatably connected with a connecting plate, the oil and gas spray pipe is arranged on the connecting plate, a cylinder is hinged on the connecting plate, a lifting screw rod is connected to the lower end face of the support seat, a rotating rod is rotatably connected to the upper support plate of the base, the lifting screw rod is screwed inside the rotating rod, a first bevel gear is fixedly arranged on the outer peripheral surface of the tail of the rotating rod, a reduction motor is fixedly connected to the lower support plate of the base, and a second bevel gear is sleeved on the output shaft of the reduction motor. After adopting the above technical solution, the oil spraying device for a single-sided jacquard weft knitting machine provided by the utility model has the characteristics of simple structure and high oil spraying efficiency, and can spray oil on the jacquard blade pins on the jacquard blades in all directions.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.

[0027] Refer to Figure 1 、 Figure 2 、 Figure 4, An embodiment provided by the present utility model: An oil spraying device for a single-sided jacquard weft knitting machine used in mattress fabric processing, including a lower needle cylinder 1 and a base 4. A jacquard piece 2 is installed on the right surface of the lower needle cylinder 1. The top of the right surface of the jacquard piece 2 is provided with a saddle 3. The right end of the upper surface of the saddle 3 is in a convex shape. The right surface of the jacquard piece 2 is provided with needle feet 21. There are multiple groups of needle feet 21, which are distributed in an array on the right surface of the jacquard piece 2. A positioning component is arranged on the upper surface of the base 4. The positioning component can control the height of the oil spray pipe 78. The positioning component includes a sliding rod 53. A support seat 6 is fixedly connected to the upper surface of the sliding rod 53. The support seat 6 and the oil spray pipe 78 will rise and fall synchronously. A swinging component is arranged on the right surface of the support seat 6. The swinging component can drive the oil spray pipe 78 to swing horizontally, thereby expanding the oil spraying range and making the oil spray more evenly. The swinging component includes a motor two 71. The motor two 71 is a prior art and can be realized by those skilled in the art. Since it is a prior art, it will not be described in detail in this case. The output shaft of the motor two 71 is fixedly connected with a worm 72. Starting the motor two 71 can drive the worm 72 to rotate. The swinging component also includes a worm gear 73. One end of a connecting rod 74 is hinged to the lower surface of the worm gear 73. When the worm gear 73 rotates, it will drive the connecting rod 74 to move. The other end of the connecting rod 74 is hinged to a cam 75. The moving connecting rod 74 will drive the cam 75 to swing. The upper surface of the cam 75 is fixedly connected with a rotating shaft 76. When the cam 75 swings, it will rotate around the rotating shaft 76. According to Figure 3 As shown, the rotation angle of the cam 75 does not exceed 180 degrees. The upper surface of the rotating shaft 76 is fixedly connected with a connecting seat 77. And when the cam 75 swings, it will drive the rotating shaft 76 and the connecting seat 77 to swing. Since the worm gear 73 is constantly rotating, the rotating shaft 76, the connecting seat 77 and the cam 75 swing reciprocally. The right surface of the connecting seat 77 is provided with an oil spray pipe 78. The oil spray pipe 78 can spray lubricating oil onto the needle feet 21, start the lubrication effect and reduce the mechanical wear. The oil spray pipe 78 is a prior art and can be realized by those skilled in the art. Since it is a prior art, it will not be described in detail in this case. Starting the oil spray pipe 78 can perform oil spraying.

[0028] Referring to Figure 1 - Figure 3 , the positioning component further includes a motor one 51. The motor one 51 is a prior art and can be realized by those skilled in the art. Since it is a prior art, it will not be described in detail in this case. The motor one 51 is a reduction motor, and the rotation speed can be adjusted to a slower state. The output shaft of the motor one 51 is fixedly connected with a guide rod 52. An arc-shaped groove 501 is opened on the outer wall of the guide rod 52. A slider 54 is fixedly connected to the inner wall of the front side of the sliding rod 53. The sliding rod 53 and the slider 54 will move synchronously.

[0029] Referring to Figure 1 、 Figure 2 、Figure 4 , the base 4 is arranged on the right side of the lower needle cylinder 1. The sliding rod 53 penetrates and is slidably connected to the upper surface of the base 4, and slides longitudinally. The second motor 71 is arranged on the right surface of the support base 6. The worm 72 penetrates and is rotatably connected to the right surface of the support base 6. The worm gear 73 is rotatably connected to the inner wall at the top of the support base 6. The worm 72 and the worm gear 73 are engaged. The worm 72 and the worm gear 73 are prior arts and can be realized by those skilled in the art. Since they are prior arts, they will not be described in detail in this case. The worm 72 can drive the worm gear 73 to rotate, the worm gear 73 cannot drive the worm 72 to rotate, and when the worm 72 rotates one circle, the worm gear 73 only rotates one tooth, so as to accurately control the swinging speed of the fuel injection pipe 78. One end of the connecting rod 74 is located at a position away from the center of the circle on the lower surface of the worm gear 73, and the other end of the connecting rod 74 is located at the left end of the lower surface of the cam 75. When the worm gear 73 rotates, under the transmission of the connecting rod 74, the cam 75 will swing. The rotating shaft 76 penetrates and is rotatably connected to the upper surface of the support base 6.

[0030] Refer to Figure 1 - Figure 3 , the first motor 51 is arranged on the inner wall at the top of the base 4. The arc-shaped groove 501 is formed in an arc shape. The slider 54 is slidably connected to the inner wall of the arc-shaped groove 501. When the guide rod 52 rotates, it will drive the arc-shaped groove 501 to rotate, further squeezing the slider 54 and driving the slider 54 and the sliding rod 53 to move longitudinally back and forth.

[0031] Working principle: When it is necessary to lubricate the pins 21 by spraying oil, start the first motor 51 and the fuel injection pipe 78. The first motor 51 will drive the guide rod 52 to rotate. Since the arc-shaped groove 501 formed on the outer wall of the guide rod 52 is slidably connected to the slider 54 on the inner wall of the sliding rod 53, when the guide rod 52 rotates, the arc-shaped groove 501 rotates accordingly and squeezes the slider 54, driving the slider 54 and the sliding rod 53 to move longitudinally back and forth.

[0032] The support base 6 fixedly connected to the upper surface of the sliding rod 53 and the associated fuel injection pipe 78 will rise and fall synchronously, so as to realize the adjustment of the fuel injection height.

[0033] At the same time, start the second motor 71, and the output shaft of the second motor 71 drives the worm 72 to rotate. Since the worm 72 is engaged with the worm gear 73, the rotation of the worm 72 will drive the worm gear 73 to rotate.

[0034] One end of the connecting rod 74 hinged at a position away from the center of the circle on the lower surface of the worm gear 73, and the other end is hinged at the left end of the lower surface of the cam 75. When the worm gear 73 rotates, it will drive the connecting rod 74 to move, so that the cam 75 swings around the rotating shaft 76 as the axis.

[0035] Since the connecting seat 77 fixedly connected to the upper surface of the rotating shaft 76 is provided with an oil spray pipe 78, when the cam 75 swings, it will drive the rotating shaft 76, the connecting seat 77 and the oil spray pipe 78 to swing horizontally.

[0036] By controlling the oil injection height with the above-mentioned first motor 51 and controlling the horizontal swing of the oil injection with the second motor 71, the oil spray pipe 78 can evenly spray lubricating oil onto multiple groups of pins 21 distributed in an array, achieving a good lubrication effect and reducing the wear of the machine.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
