Description

Technical Field

[0001] The present invention relates to the technical field of jacquard machines, especially to the technical field of an efficient circular knitting machine for curtain and towel jacquard weaving. Background Art

[0002] A towel jacquard machine is a machine that can form various patterns and designs on the surface of a towel through jacquard technology; the working principle of a towel jacquard machine is mainly based on the cooperation of a jacquard device and a knitting program (first, the designed pattern is converted into a knitting program and transmitted to the loom through the jacquard device, and the loom can control the movement of components such as knitting needles and weft yarns according to the received knitting program to form a pattern on the surface of the towel).

[0003] Although existing towel jacquard machines can endow the fabric with the characteristics of high-low pile jacquard (having a high-low concave-convex effect on the fabric surface), they can often only produce fabrics with a small width (the width of the fabric can usually only reach 1.5 m to meet the towel production requirements and cannot simultaneously produce curtains that require a fabric width of 2.8 - 3.2 m); in addition, if the towel jacquard machines on the market are directly used for curtain production, they cannot achieve sufficient weaving efficiency. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the prior art and propose an efficient circular knitting machine for curtain and towel jacquard weaving, which not only has a high output but also can produce fabrics with a relatively large width, and can simultaneously meet the large-scale preparation of jacquard curtain fabrics.

[0005] To achieve the above purpose, the present invention proposes an efficient circular knitting machine for curtain and towel jacquard weaving, including a machine body, a needle cylinder, lower needles, lower cams, sinkers, jacquard blades, a jacquard selector, and upper cams. The needle cylinder is rotatably connected to the machine body and has a number of needle grooves with lower needles vertically inserted respectively. Each of the lower needles is respectively provided with a sinker and a jacquard blade that cooperates with the sinker. The lower cams and the upper cams are respectively fixed on the machine body and can guide the vertical movement of each lower needle and each sinker perpendicular to each other. The jacquard selector is arranged close to the upper cam and is used to toggle and select the jacquard blades. The needle cylinder has a diameter of not less than 1200 mm.

[0006] Preferably, a number of insertable blade sockets and blade tenons are respectively provided between each pair of corresponding sinkers and jacquard blades. Each of the lower needles is respectively provided with a needle hook at the top, and each of the sinkers is respectively provided with a blade nose that can cooperate with the corresponding needle hook.

[0007] Preferably, each of the lower needles is respectively provided with a plurality of needle heels on one side facing the lower triangle, and a lower guide rail for each needle heel to slide into is provided above the lower triangle. Each sinker is respectively provided with a plurality of sinker heels on one side facing the upper triangle, and an upper guide rail for each sinker heel to slide into is provided above the upper triangle.

[0008] Preferably, each sinker is further provided with a material guiding convex portion below the nose of the sinker, and a material guiding groove for each material guiding convex portion to extend into is provided on the needle cylinder.

[0009] Preferably, the jacquard selector cooperates with each jacquard blade through a selector head and a jacquard head.

[0010] Preferably, the lower triangle is indirectly connected to the machine body through a lower bracket. The lower bracket includes a lower seat plate, a lower seat body and a slider. The lower seat plate is installed on the machine body, the lower seat body is installed on the lower seat plate, the slider can first slide relative to the lower seat body and then be fixed to the lower seat body through a fastener, and the lower triangle is installed on the slider.

[0011] Preferably, the upper triangle is indirectly connected to the machine body through an upper bracket. The upper bracket includes an inner heart ring, an outer heart ring and a seven-character foot. The inner heart ring and the outer heart ring can rotate relative to each other. The upper triangle and the jacquard selector are respectively installed on the inner heart ring and the outer heart ring. The outer heart ring is installed on the seven-character foot, and the seven-character foot is installed on the machine body.

[0012] Preferably, the machine gauge is at least 70.

[0013] Advantages of the present invention: 1) By using the laterally movable sinkers and jacquard blades in cooperation with the vertically movable lower needles to complete jacquard, a fabric with a strong three-dimensional sense and a high-low hair effect can be produced. And since the diameter of the needle cylinder is not less than 1200 mm, even if conventional yarns (150 DFDY / DTY) are selected, the width of the produced fabric can reach 2.8 - 3.2 m, thus meeting the preparation requirements of strong three-dimensional jacquard curtains; 2) By increasing the machine gauge to at least 70, the daily output of the machine can reach more than 300 kg (high output) on the basis of ensuring the lightness and strong three-dimensional sense of the curtain fabric; 3) By cooperatively arranging the material guiding convex portions and the material guiding grooves on the sinkers and the needle cylinder, the yarn debris generated by jacquard can be quickly discharged by the material guiding convex portions and the material guiding grooves, avoiding the gradual accumulation of impurities generated by yarn wear on parts such as sinkers and affecting the normal operation of the machine.
