Description

Technical Field

[0001] This utility model is a multifunctional circular knitting machine, belonging to the field of circular knitting machines. Background Technology

[0002] The circular knitting machine is a specialized piece of machinery used to produce various knitted fabrics, and it holds an extremely important position in the textile industry.

[0003] Circular knitting machines primarily operate by using needles on a series of cylinders (or needle discs). These needles are arranged in a specific pattern and move up and down to form loops, which are then knitted into fabric. Based on different knitting methods, circular knitting machines can be broadly classified into single-jersey machines and double-jersey machines. Single-jersey machines are mainly used for knitting fabrics with simple structures such as plain weave; while double-jersey machines can knit fabrics with various complex structures such as rib knit and air-layered fabric.

[0004] The core components of the machine include: cylinder, needles, cam system, yarn creel, yarn feeding mechanism, and take-up / winding device. The cylinder is the main component that carries the needles, which are the key elements directly involved in the knitting process. The cam system controls the movement trajectory of the needles, ensuring they accurately complete each knitting motion. The yarn creel and yarn feeding mechanism ensure the yarn smoothly enters the knitting area, while the take-up / winding device smoothly pulls and winds the knitted fabric.

[0005] The fabric output port of existing circular knitting machines is a fixed structure. When it is necessary to adapt to the position of the fabric roll machine to transport the fabric, it is often necessary to connect a fabric transport positioning structure to the fabric output port, which is quite inconvenient. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a multifunctional circular knitting machine that solves the problem that existing circular knitting machines have a fixed fabric output port, which often requires an additional fabric conveying and positioning structure to be connected to the fabric output port when the fabric needs to be conveyed to the position of the fabric roll-up machine, which is quite inconvenient.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a multi-functional circular knitting machine, the structure of which includes a circular knitting machine base and a circular knitting machine knitting end; the circular knitting end is located on the upper end of the circular knitting machine base; the bottom of the circular knitting machine base has a groove, the top surface of which is provided with a fabric outlet corresponding to the circular knitting end, and the fabric outlet is provided with an adjustable fabric positioning structure for adjusting the output position of the fabric, which is applicable to various types of roll fabric structures;

[0008] The adjustable fabric positioning structure includes a positioning seat and a movable seat. The movable seat is movably disposed at the bottom of the positioning seat. The positioning seat has a fabric channel in the middle and an output port corresponding to the fabric channel in the middle of the movable seat. The bottom surface of the positioning seat has a drive groove on both the left and right sides. The drive groove contains a drive cylinder with its output end facing downward. The top surface of the movable seat has a rotation groove on both the left and right sides. The bottom surface of the rotation groove has a hinge piece that is hinged to the output end of the drive cylinder. The bottom surface of the movable seat is screwed with a limiting bolt. The top of the limiting bolt extends into the rotation groove and is in close contact with the output end of the drive cylinder. When the limiting bolt is tightened, it can effectively prevent the output end of the drive cylinder from rotating on the hinge piece, thus achieving the effect of positioning and limiting.

[0009] Furthermore, in order to perform the fabric winding operation, a fabric winding machine is also included, which is located in the slot of the large circular knitting machine base.

[0010] Furthermore, to prevent occupying additional space, the fabric rolling machine is located directly below the movable seat.

[0011] Furthermore, for ease of operation, the outer wall of the large circular machine base is equipped with a control panel for controlling the operation of the drive cylinder.

[0012] Furthermore, in order to position the output end of the drive cylinder, the hinge plate is provided with a rotating shaft that is rotatably connected to the output end of the drive cylinder for positioning.

[0013] Furthermore, in order to improve driving efficiency, the driving cylinder is one of an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder.

[0014] Furthermore, to improve the strength of the connection, the hinge plate and the movable seat are connected by welding or bolting.

[0015] Furthermore, to prevent scratching the groove of the large circular machine base during movement, the cross-section of the movable seat is an inverted isosceles trapezoidal structure.

[0016] Furthermore, to improve the stability of the connection, the positioning seat and the base of the large circular machine are integrally formed.

[0017] Furthermore, to prevent rust and corrosion, the limiting bolts are made of stainless steel.

[0018] The beneficial effects of this utility model are as follows: The fabric outlet of the circular knitting machine is equipped with an adjustable fabric positioning structure, which allows for quick adjustment of the fabric conveying angle, effectively improving the convenience of operation for workers. When the tilt angle needs to be adjusted, the output end of the drive cylinder extends, driving the movable seat away from the positioning seat. Then, the movable seat is rotated to the appropriate angle with the hinge plate. Finally, the limiting bolt is tightened to stop the output end of the drive cylinder and limit the positioning, thus completing the adjustment work. The operation is simple. The fabric knitted by the circular knitting end of the machine will pass through the fabric channel of the positioning seat, then enter the output port of the movable seat, and finally be fed into the winding machine for winding.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Example 1

[0025] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution for a multifunctional circular knitting machine:

[0026] like Figure 1 As shown, the position of the adjustable fabric positioning structure 3 according to Embodiment 1 of this utility model will be described in detail;

[0027] Its structure includes a circular knitting machine base 1 and a circular knitting machine end 2; the circular knitting machine end 2 is located on the upper end of the circular knitting machine base 1.

[0028] The base 1 of the circular knitting machine has a slot at the bottom. The top surface of the slot is provided with a fabric outlet corresponding to the knitting end 2 of the circular knitting machine. The fabric outlet is provided with an adjustable fabric positioning structure 3 for adjusting the output position of the fabric. It is applicable to various types of roll fabric structures. The slot plays a role in assembling and positioning the adjustable fabric positioning structure 3.

[0029] like Figure 2 As shown, the specific structure of the adjustable fabric positioning structure 3 according to Embodiment 1 of this utility model will be described in detail.

[0030] The adjustable fabric positioning structure 3 includes a positioning seat 31 and a movable seat 32. The movable seat 32 is movably disposed at the bottom end of the positioning seat 31. The positioning seat 31 has a fabric channel 33 in the middle, and the movable seat 32 has an output port 34 corresponding to the fabric channel 33 in the middle. The bottom surface of the positioning seat 31 has a drive groove 35 on both the left and right sides. The drive groove 35 contains a drive cylinder 36 with its output end facing downward. The top surface of the movable seat 32 has a rotating groove 37 on both the left and right sides. The bottom surface of the rotating groove 37 has a hinge piece 38 that is hinged to the output end of the drive cylinder 36. The bottom surface of the movable seat 32 is screwed with a limiting bolt 39. The top of the limiting bolt 39 extends into the rotating groove 37 and is in close contact with the output end of the drive cylinder 36. When the limiting bolt is tightened, it can effectively prevent the output end of the drive cylinder from rotating on the hinge piece, thus achieving the effect of positioning and limiting.

[0031] In order to perform the fabric winding operation, a fabric winding machine 4 is also included. The fabric winding machine 4 is located in the slot of the circular knitting machine base 1. The fabric output from the circular knitting machine will be wound up by the fabric winding machine 4.

[0032] To prevent additional space occupation, the fabric rolling machine 4 is located directly below the movable seat 32.

[0033] For ease of operation, the outer wall of the base 1 of the large circular machine is equipped with a control panel for controlling the operation of the drive cylinder 36. By operating the control panel, the operator can control the output end of the drive cylinder 36 to extend and retract.

[0034] like Figure 3 As shown, the connection features of the hinge piece 38 according to Embodiment 1 of the present invention will be described in detail.

[0035] In order to position the output end of the drive cylinder 36, the hinge plate 38 is provided with a rotating shaft that is rotatably connected to the output end of the drive cylinder 36, so that when the output end of the drive cylinder 36 is not restricted by the limiting bolt, it can swing around the center of the rotating shaft on the hinge plate 38.

[0036] To improve driving efficiency, the driving cylinder 36 is one of an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder, with an electric cylinder being preferred.

[0037] An electric cylinder (also known as an electric actuator) is a device that converts electrical energy into mechanical motion. This type of device is mainly used to achieve linear or rotary motion to complete various automated tasks. Electric cylinders are typically driven by an electric motor and achieve the desired motion through a mechanical transmission mechanism (such as a lead screw, gears, etc.).

[0038] Compared to traditional pneumatic or hydraulic cylinders, electric cylinders offer numerous advantages, including higher precision and repeatability, cleaner operation (due to the absence of hydraulic fluid), lower maintenance requirements, and easier integration with digital control systems. Consequently, they are widely used in industrial automation, robotics, medical devices, aerospace, and other fields.

[0039] A hydraulic cylinder is an actuator in a hydraulic system that converts hydraulic energy into mechanical energy to achieve linear reciprocating motion or oscillation.

[0040] A cylinder, also known as a pneumatic cylinder or pneumatic cylinder, is an actuator that uses compressed air as a power source to generate linear motion.

[0041] To improve the strength of the connection, the hinge piece 38 and the movable seat 32 are connected by welding. However, this utility model is not limited to this method; it is sufficient as long as the hinge piece 38 and the movable seat 32 can be connected and fixed.

[0042] To prevent scratching of the groove of the large circular machine base 1 during operation, the cross-section of the movable seat 32 is an inverted isosceles trapezoidal structure, or the cross-section of the movable seat 32 can be a conical structure.

[0043] To improve the stability of the connection, the positioning seat 31 and the large circular knitting machine base 1 are integrally formed. However, this utility model is not limited to this; it is sufficient that the positioning seat 31 and the large circular knitting machine base 1 can be connected and fixed.

[0044] To prevent rust and corrosion, the limiting bolt 39 is made of stainless steel. However, this invention is not limited to this, and the limiting bolt 39 may also be made of other alloy materials.

[0045] The circular knitting machine has an adjustable fabric positioning structure 3 at the fabric outlet, which allows for quick adjustment of the fabric conveying angle, effectively improving the convenience of operation for workers. When the tilt angle needs to be adjusted, the output end of the drive cylinder 36 extends, driving the movable seat 32 away from the positioning seat 31. Then, the movable seat 32 is rotated to the appropriate angle with the hinge piece 38. Finally, the limiting bolt 39 is tightened to stop the output end of the drive cylinder 36 and limit the positioning, thus completing the adjustment work. The operation is simple. The fabric knitted by the knitting end 2 of the circular knitting machine will pass through the fabric channel 33 of the positioning seat 31, and then enter the output port 34 of the movable seat 32, and finally be fed into the winding machine 4 for winding.

[0047] For the sake of brevity, the parts that are the same as those in other embodiments will not be described again. The main description is of the structure that is different from other embodiments of this utility model. The hinge piece 38 and the movable seat 32 can also be connected by bolts. This connection effectively improves the convenience of subsequent disassembly and maintenance.
