Description

Technical Field

[0001] The utility model relates to the technical field of knitting machines, in particular to a precision open-width knitting machine. Background Art

[0002] The needle pressing cam is a key component of a double-sided rib cloth knitting machine. In order to ensure the quality of the weaving, the position of the needle pressing cam needs to be adjusted. In order to improve the adjustment effect, the prior art (CN111549440B) discloses a needle pressing cam of a double-sided rib knitting machine, which is provided with an adjustment plate position adjustment mechanism and a needle pressing cam position adjustment mechanism, so that the position of the adjustment plate can be adjusted to achieve overall adjustment, and the position of the needle pressing cam can be adjusted to achieve independent adjustment of the needle pressing cam.

[0003] Although the above technology can realize overall adjustment and independent adjustment of the triangle, it can only adjust the height of the triangle. The pressing triangle is usually composed of multiple triangles. When different types of fabrics need to be made, different types of pressing triangles need to be replaced, which is more cumbersome.

[0004] In view of the defects existing in the above prior art, it is necessary to further improve it to make it more practical so as to meet the actual usage. Utility Model Content

[0005] The purpose of the utility model is to provide a precision open-width knitting machine to solve the problems raised by the above-mentioned background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a precision open width knitting machine, comprising a cam seat, a cam assembly located on the cam seat, and a knitting needle matched with the cam assembly, wherein the knitting needle is located on a needle cylinder,

[0007] The cam assembly consists of a lower flat needle cam, a lower half needle cam and a lower needle exit cam, and the lower flat needle cam, the lower half needle cam and the lower needle exit cam are all bolted to a fixed plate.

[0008] The fixed plate on the lower needle outlet triangle is fixed to the sliding plate through a first sliding mechanism;

[0009] The fixing plates on the lower flat needle cam and the lower half needle cam are fixed to the sliding plate through a second sliding mechanism;

[0010] The sliding plate is fixed on the mounting plate through a third sliding mechanism, and the mounting plate is fixed on the triangular seat through the third sliding mechanism.

[0011] As the preferred technical solution:

[0012] In the precision open-width knitting machine as described above, the first sliding mechanism and the third sliding mechanism have the same structure, both of which are linear guide rail slider structures, the first sliding mechanism is arranged horizontally, and the third sliding mechanism is arranged vertically.

[0013] Through the above technical solution, the fixed plate on the lower needle outlet triangle can move laterally on the sliding plate, and the sliding plate can move vertically on the mounting plate. At the same time, the mounting plate can also move vertically on the triangle seat, so that the four groups of triangle components can be moved as a whole or adjusted and moved individually.

[0014] In the precision open-width knitting machine as described above, the sides of the fixing plates on the lower flat needle cam and the lower half needle cam extend horizontally outward to form side plates.

[0015] The second sliding mechanism includes a partition plate with a hollow structure, which is welded and fixed to the sliding plate. The top surface of the partition plate is open, and a group of guide rods are welded and connected to the inner wall of the partition plate. The guide rods pass through the sliding block, and the sliding block is bolted to the side plate. A vertical rod vertically passes through the sliding block, and the top of the vertical rod is welded to the side plate.

[0016] Through the above technical solution, the sliding block can move in a straight line on the guide rod, and then the side plate can move synchronously with the sliding block, so that the lower flat needle triangle and the lower half needle triangle can move in a straight line through the side plate, and the lower needle output triangle can move in a straight line through the linear guide slider structure, so that the lower flat needle triangle, the lower half needle triangle and the lower needle output triangle can be adjusted independently, which is convenient for sorting and combination.

[0017] In the above-mentioned precision open-width knitting machine, the two ends of the sliding plate are respectively welded to the limiting block and the protrusion, and the protrusion is penetrated by a locking screw threadedly connected thereto.

[0018] Through the above technical scheme, when the lower flat needle cam, the lower half needle cam and the lower needle outlet cam are arranged and combined, the limit block cooperates with the locking screw to clamp and limit the lower flat needle cam, the lower half needle cam and the lower needle outlet cam to avoid shaking of the three under the high-speed movement of the knitting needle, thereby ensuring the weaving quality.

[0019] In the precision open-width knitting machine as described above, three groups of grooves are provided on the sliding plate, each group of grooves has two grooves, and the backs of the lower flat needle cam and the lower half needle cam are provided with limiting protrusions matched with the grooves.

[0020] Through the above technical solution, after the adjustment of the lower flat needle cam and the lower half needle cam is completed, the limiting protrusion cooperates with the groove to further limit the lower flat needle cam and the lower half needle cam, so as to ensure the overall limiting effect.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] (1) The precision open-width knitting machine is provided with a lower flat needle cam, a lower half needle cam and a lower needle exit cam. The three types of cams can be arranged and combined to produce various types of fabrics. At the same time, the needle track curve design of the cam is smoother, which can reduce the pressure on the needle shaft of the knitting needle during high-speed operation, which is beneficial to ensure the quality of weaving.

[0023] (2) The precision open-width knitting machine has four sets of cam assemblies. Each set of cam assemblies can slide on the mounting plate through a sliding plate, so that the height of each set of cam assemblies can be adjusted. At the same time, the mounting plate can slide on the cam seat, so that the four sets of cam assemblies can be adjusted synchronously. Therefore, the device can be adjusted individually or as a whole, thereby improving the adjustment effect.

[0024] (3) The precision open-width knitting machine is provided with a first sliding mechanism and a second sliding mechanism. The lower flat needle cam, the lower half needle cam and the lower needle exit cam can slide independently, so that the three can be quickly sorted and combined according to the different types of fabrics to be made, and the operation is convenient.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-Figure 2 The utility model provides a technical solution: a precision open width knitting machine, comprising a cam seat 1, a cam assembly located on the cam seat 1, and a knitting needle 17 matched with the cam assembly, the knitting needle 17 is located on a needle cylinder 18, and the cam assembly is composed of a lower flat needle cam 2, a lower half needle cam 3 and a lower needle outlet cam 4.

[0033] When the knitting needle 17 moves at high speed with the needle cylinder 18, the butt of the knitting needle 17 can move in the needle tracks in the lower flat needle triangle 2, the lower half needle triangle 3 and the lower needle triangle 4, so that the knitting needle 17 can move to realize the weaving operation.

[0034] like Figure 1-2 As shown, the lower flat needle triangle 2, the lower half needle triangle 3 and the lower needle outlet triangle 4 are all bolted to the fixed plate 5, the fixed plate 5 on the lower needle outlet triangle 4 is fixed to the sliding plate 6 through a first sliding mechanism, the fixed plate 5 on the lower flat needle triangle 2 and the lower half needle triangle 3 is fixed to the sliding plate 6 through a second sliding mechanism, the sliding plate 6 is fixed to the mounting plate 7 through a third sliding mechanism, and the mounting plate 7 is fixed to the triangle seat 1 through the third sliding mechanism. The structures of the first sliding mechanism and the third sliding mechanism are consistent, and both are linear guide rail slider structures. The first sliding mechanism is horizontally arranged, and the third sliding mechanism is vertically arranged.

[0035] When the equipment is being debugged, it is necessary to synchronously adjust the positions of the lower flat needle triangle 2, the lower half needle triangle 3 and the lower needle outlet triangle 4. During adjustment, the sliding plate 6 can be slid on the mounting plate 7, and then each group of triangle components can be moved individually. When the mounting plate 7 is moved on the triangle seat 1, the four groups of triangle components can be moved synchronously, and then the device can be adjusted and moved as a whole, or a single group can be adjusted and moved, thereby improving the adjustment effect.

[0036] After the sliding plate 6 and the mounting plate 7 are adjusted, in order to keep the sliding plate 6 and the mounting plate 7 in a fixed state, corresponding limiting components are further provided, such as being locked and fixed by bolts.

However, when the three need to be sorted and combined, since the vertical rod 12 can be moved vertically on the sliding block 11, the lower flat needle cam 2 and the lower half needle cam 3 can be moved horizontally along the Y direction and at the same time, they can also be moved along the X direction.

[0039] When the lower flat needle triangle 2 or the lower half needle triangle 3 is pulled, the lower flat needle triangle 2 can cross the lower half needle triangle 3 and the lower needle exit triangle 4, and the lower half needle triangle 3 can cross the lower flat needle triangle 2 and the lower needle exit triangle 4, and then the positions of the lower flat needle triangle 2 and the lower half needle triangle 3 can be exchanged, and the positions of the lower half needle triangle 3 and the lower needle exit triangle 4 can also be exchanged.

[0040] like Figure 2 and Figure 5 As shown, the two ends of the sliding plate 6 are respectively welded to a limit block 13 and a protrusion 14, and the protrusion 14 is penetrated by a locking screw 15 threadedly connected thereto. The sliding plate 6 is provided with three groups of grooves 16, and each group of grooves 16 has two grooves.
