Description

Technical Field

[0001] The utility model relates to the technical field of knitting machinery, in particular to a simple lifting brush device for a computerized flat knitting machine. Background Art

[0002] Computerized flat knitting machine is a double-needle plate latch needle weft knitting loom, which is a high-tech product in the field of knitting machinery. All its knitting-related actions are realized by pre-programmed programs, which send action signals to each actuator through a computer controller to drive the relevant mechanisms and parts. As a high-tech product in the field of knitting machinery, computerized flat knitting machine has broad market prospects and development space. With the continuous advancement of technology and the continuous growth of market demand, computerized flat knitting machine will play an increasingly important role in the knitting garment industry.

[0003] The brush mechanism on a computer flat knitting machine, especially the flat brush, mainly plays the role of brushing open the closed needle tongues on the working needles. During the knitting process, due to the frequent movement of the needles, the needle tongues may be closed for various reasons, which will affect the normal passage of the yarn and the smooth progress of knitting. The brush mechanism can effectively brush open these closed needle tongues through the brushing of its bristles, ensuring that the yarn can pass through the needle tongues smoothly, thereby avoiding problems such as yarn breakage and missed needles during the knitting process. The problems of the existing computer flat knitting machine brush mechanism during use mainly involve the installation, adjustment, and maintenance of the bristles. Bristles that are severely worn need to be replaced in time to ensure that the brush mechanism can work normally and protect the needles and yarn. Therefore, the entire brush mechanism needs to be replaced and maintained, and the brush needs to be adjusted in angle and stroke to ensure that the bristles of the brush body have a brushing effect on the needle tongues of the knitting needles. This method has many operating steps and is inconvenient for the operator to adjust. For this reason, we propose a simple lifting brush device for a computer flat knitting machine to solve the above problems. Utility Model Content

[0020] See also Figure 1-Figure 2 The utility model provides a technical solution: a simple lifting brush device for a computerized flat knitting machine, comprising a motor base 1, a motor 2 arranged at one end of the motor base 1, and a brush assembly 8 arranged at the output end of the motor 2. The motor base 1 is composed of a vertical surface 11 and a mounting surface 12. The vertical surface 11 is mounted on one end of the mounting surface 12 by bolts and is arranged perpendicular to the mounting surface 12. The motor 2 is clamped in the gap between the vertical surface 11 and the mounting surface 12.

[0021] A through groove is provided on the vertical surface 11, the output end of the motor 2 passes through the vertical surface 11, and the brush assembly 8 is movably arranged on the outside of the vertical surface 11. The motor 2 can control the output end to drive the brush assembly 8 to move, so that it can effectively clean impurities and dust on the knitting needles and yarns, reduce the possibility of yarn entanglement and knotting, and thus improve the weaving efficiency and quality.

[0022] like Figure 1As shown, a gear 3 is installed on the output end of the motor 2, and a rack 4 is provided on one side of the gear 3. The rack 4 is movably arranged on one side of the vertical plane 11 and meshes with the gear 3. The rack 4 can follow the gear 3 to make reciprocating motion, and is used to drive the brush assembly 8 to move. With the help of the motor 2, the gear 3 can be driven to make reciprocating circular motion, thereby moving the rack 4 meshed on one side, thereby controlling the movement and operation of the brush assembly 8 inside the device.

[0023] In order to control the activity limit range of the brush assembly 8 during the operation of the equipment, a limit block 5 is further provided on one side of the vertical surface 11. The limit block 5 is installed on the vertical surface 11. A positioning groove 41 is provided on the rack 4. The positioning groove 41 is wider than the width of the limit block 5. The rack 4 is movably clamped on the limit block 5. The limit block 5 is used to adjust the stroke range of the rack 4. A baffle 6 is provided on the outside of the limit block 5. The baffle 6 is used to block the rack 4 and thus play a limiting role. With the help of the limit block 5 and the baffle 6, it can be pressed against the outside of the rack 4 to control the extreme activity range and feed direction of the rack 4, thereby ensuring the subsequent cleaning efficiency and the overall weaving quality of the equipment.

[0024] In order to improve the maintenance efficiency of the equipment, an adapter plate 7 is installed at the bottom of the rack 4. The adapter plate 7 is vertically bent and is attached to the outer wall of the bottom of the rack 4. An extension plate is provided on the side of the adapter plate 7 parallel to the mounting surface 12. The brush assembly 8 is installed on the surface of the extension plate. The brush assembly 8 can be disassembled separately and can be maintained and replaced in the event of internal wear and tear to avoid affecting the subsequent weaving quality.

[0025] In order to ensure the cleaning efficiency of the equipment, a pair of fixing holes are opened on the brush assembly 8, and positioning pins are installed inside the fixing holes. The stroke of the brush assembly 8 can be adjusted and controlled for precise control of the action on the knitting needles and yarns that need to be cleaned.

[0026] like Figure 2 As shown, the equipment can be adjusted to different yarns during operation, and a sensor 10 is provided on the surface of the mounting surface 12. The sensor 10 is located on one side of the motor 2, and a magnetic steel seat 9 is provided on the end of the motor 2 close to the sensor 10. The magnetic steel seat 9 is annular and has a pair of magnetic axes extending from the surface at an obtuse angle, and one end of the magnetic axis can be against the sensor 10, which is used for the sensor 10 to cooperate with the brush to achieve the lifting stroke of the brush. The position of the sensor 10 and the magnetic steel seat 9 can be adjusted to achieve the lifting stroke of the brush at the bottom of the brush assembly 8 according to different situations, thereby ensuring the combing quality, and controlling the weaving accuracy to ensure that the yarn remains flat and stable during the weaving process, and reducing wear, thereby controlling the cost of use.

[0027] Working principle: When in use, the motor 2 is installed on the motor base 1. The motor base 1 has two vertical surfaces 11 and 12. The surface 11 is for placing the motor 2, and the surface 12 is the installation surface, which is installed on the external head box. The motor 2 has a double output shaft, and the gear 3 is installed on one side of the output shaft of the motor 2. The limit block 5 is installed on the surface 11 of the motor base 1. The rack 4 is provided with a positioning groove 41, which is placed on the limit block 5 and then blocked by a baffle 6. The width of the limit block is slightly smaller than the positioning groove 41 of the rack 4, and the height is slightly larger than the thickness of the rack 4, so that the rack 4 can move up and down along the length direction of the limit block 5, which can play an auxiliary limiting role. The brush assembly 8 is connected to the rack 4 through the adapter plate 7, which is convenient for subsequent disassembly and maintenance. The rack 4 and the gear 3 are matched in a rack and gear system. Finally, the brush assembly 8 is driven up and down by the motor 2. A magnetic steel seat 9 is installed on the shaft on the other side of the motor 2, which cooperates with the sensor 10 to realize the lifting stroke of the brush at the bottom of the brush assembly 8, ensuring the combing quality and also controlling the weaving accuracy to ensure that the yarn remains flat and stable during the weaving process.
