Description

Technical Field

[0001] The utility model relates to the field of glove knitting machines, in particular to a triangular mechanism of a glove knitting machine. Background Art

[0002] The basic structure of the computer glove machine is: between the left and right bases, there are front and rear needle beds, movable knitting needles are arranged in the needle grooves of the needle beds, and cam bottom plates are arranged on the split front and rear heads, and the cam bottom plates move left and right with the heads; because various cams are arranged on the cam bottom plates, the needles are selected, started and cleared through the interaction of the needle butts of the cams and the knitting needles (combination needles), so as to complete various knitting functions.

[0003] The cylindrical part of the palm and fingers of the knitted gloves is generally called normal knitting, while the wrist needs to introduce elastic thread for knitting to make it elastic, which is generally called elastic knitting. The tightness of the coil is controlled by the respective triangles during normal knitting and elastic knitting, and the tightness required by the two is inconsistent. In the commonly used knitted gloves, the downward pressure amplitude of the density triangle controlling the normal knitting on the triangle bottom plate is greater than the downward pressure amplitude required by the triangle during elastic knitting; in the previous one-way knitting (that is, one side of the front and rear heads is in the "idling" state and does not participate in knitting in one back and forth), this limitation will not cause technical problems; however, with the development of double-sided knitting technology, the head will involve needle raising in the back and forth process, that is, two needle raising triangles and two density triangles are arranged on a triangle bottom plate. Under such conditions, the downward pressure amplitude of the density triangle on the same side as the elastic triangle (the elastic triangle is used to introduce the elastic thread) will affect the downward pressure amplitude during elastic knitting, that is, it will increase the downward amplitude of the knitting needle that eats the elastic thread, which will lead to the breakage of the elastic thread or the size and tightness of the glove ribbing part cannot be controlled.

[0004] Therefore, in double-sided weaving, it is necessary to consider that when the elastic band is weaved, it is affected by the downward pressure of the density triangle, which may cause the elastic band line to break easily or the tightness of the ribbing part of the glove to be uncontrollable.

[0005] The solution to this problem in the existing technology is to set an additional driving force for actively controlling the up and down movement of the density triangle in the drive, so that the density triangle can be driven to rise and make way when the elastic band is knitted, so that the downward pressure amplitude meets the knitting requirements; and when knitting the same batch of gloves, the single-sided knitted density triangle only needs to adjust the up and down position before starting knitting, and does not need to be moved frequently during knitting. Therefore, this method increases the burden on the machine head during operation and increases the production cost.

[0006] For the above reasons, the inventor of the present invention conducted further research and developed a glove knitting machine triangle mechanism, which resulted in the present invention. Utility Model Content

[0007] The utility model aims to provide a glove knitting machine cam mechanism, which avoids the breakage of the elastic line during double-sided knitting and improves the production efficiency.

[0008] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0009] A glove knitting machine cam mechanism comprises a cam bottom plate, on which are arranged a rubber cam, a rubber auxiliary cam and a density cam; wherein:

[0010] The elastic triangle is arranged below the elastic auxiliary triangle, and the density triangle is arranged on the side of the elastic auxiliary triangle; the density triangle includes a compression slope and a compression plane, and the density triangle can be extended and retracted relative to the triangle bottom plate, and at the same time, the side of the density triangle close to the elastic auxiliary triangle is the compression slope, and the sides of the compression slope and the compression plane jointly form the needle bottom edge of the density triangle.

[0011] The same side in the above technical solution is based on the upper Zhongshan triangle located in the middle of the triangular bottom plate, and its left side or right side can be called the same side;

[0012] The above-mentioned elastic auxiliary triangle is used to limit the needle butt from the elastic triangle to the highest point after the needle is raised to hook the thread, and then to fall down, which determines the downward pressure amplitude during elastic knitting; the needle bottom edge of the density triangle determines the downward pressure amplitude during normal knitting (the downward pressure amplitude is the amplitude of the needle pulling the thread downward after hooking the thread);

[0013] The "compression plane" here does not refer to an absolutely flat and smooth surface, but is mainly used to distinguish it from an inclined compression slope;

[0014] Theoretically, there is a situation where the downward pressure amplitude of the elastic auxiliary triangle is consistent with the height of the needle bottom edge of the density triangle. At this time, there is no need to press the density triangle into the triangle bottom plate when the needle is knitting; but in current glove knitting needs, the density limit point of the elastic auxiliary triangle is often higher than the needle bottom edge, so it is generally necessary to pass through the density limit point first and then enter the compression slope to press the density triangle into the triangle bottom plate (in the prior art, if the low point of the density triangle is used as the density limit point, the density triangle needs to be raised).

[0015] Furthermore, the compression slopes of the elastic auxiliary triangle and the density triangle partially overlap in a space perpendicular to the triangle bottom plate, and the density limiting point of the elastic auxiliary triangle is located on the compression slope.

[0016] Since the compression slope is designed as a slope, a part of the compression slope can be set between the elastic auxiliary triangle and the triangle bottom plate, so that the knitting needle can immediately act on the density triangle when passing through the density limit point, thereby improving the weaving efficiency; and the "density limit point is located on the compression slope" here means that the triangle bottom plate is the "bottom", the compression slope is above the triangle bottom plate, and the density limit point is above the compression slope.

[0017] Furthermore, the density limit point of the elastic auxiliary triangle is its lowest point, the downward pressure amplitude of elastic weaving is determined by the density limit point of the elastic auxiliary triangle, and the downward pressure amplitude of normal weaving is determined by the bottom edge of the needle.

[0018] When weaving rubber bands, start from the rubber triangle, follow the needle path between the rubber auxiliary triangle and the rubber triangle, and then pass through the density limit point, which is the downward pressure amplitude of the rubber band weaving; the lowest point here is not "unique", it can also be an "edge" composed of continuous low points.

[0019] Furthermore, a protrusion is provided below the needle moving bottom edge of the density triangle, so that a needle moving channel is formed at the bottom of the density triangle.

[0020] The needle movement channel can make the needle movement more stable when the density triangle is working.

[0021] Furthermore, the density cam is arranged in the density cam seat, and a return spring is arranged between the density cam and the density cam seat. When the butt of the knitting needle passes through the compression inclined surface, the return spring is compressed.

[0022] The density triangle is kept in an extended state by a return spring. When the density triangle is acted upon by the butt of the knitting needle, the return spring is also compressed and returns to its original position after the butt of the needle leaves.

[0023] Furthermore, the return spring is arranged in the spring seat, and the spring seat is protrudingly arranged on the density triangle seat.

[0024] Furthermore, the density triangle seat is arranged in the mounting plate, the mounting plate is arranged in the triangle bottom plate, and the thickness of the mounting plate is greater than the thickness of the triangle bottom plate.

[0025] Since the density cam needs to be set to be movable and needs to cooperate with the triangular seat, the overall thickness of the mounting plate must be greater than the commonly used triangular base plate; if the triangular base plate and the mounting plate are made into a structure with the same thickness, the weight of the entire triangular base plate will be greatly increased, resulting in an increase in the load when the machine head moves left and right, which is not conducive to production.

[0026] Furthermore, the overall profile of the density triangle is a quadrilateral structure, one side of which is a compression slope from thin to thick, and the other side is a compression plane.

[0027] Furthermore, one side of the density triangle is connected to the side of the upper Zhongshan triangle.

[0028] Furthermore, a limiting groove is arranged on the top of the upper Zhongshan triangle.

[0029] The limiting groove is used to assist in limiting the needle butt above the compound needle (the knitting needle is also a compound needle, which includes multiple needle butts and is used for needle selection, weaving and other functions. The setting of the knitting needle butt is prior art).

[0030] After adopting the above scheme, the utility model has the following advantages compared with the prior art:

[0031] By designing the entire density triangle to be avoidable, the triangle device does not need to pass through the bottom edge of the needle of the density triangle when weaving rubber bands, thereby avoiding the rubber band line from being too tight and breaking. The overall structure is simple, it is not an active avoidance drive, the production cost is low, and the load on the machine head is small. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0050] In the following embodiments, the cam device (machine head) actually moves horizontally, while the knitting needles are stationary in the horizontal direction of the glove machine. However, in the figures, the cam bottom plate is used as a reference, so it is equivalent to the knitting needles moving.

[0051] Embodiment 1:

[0052] In the bidirectional knitting of the glove machine, two staggered machine heads can be set for synchronous knitting. The staggered synchronous knitting technology can refer to the prior patent "CN202210035315.4".

[0053] like Figure 1 , 3 As shown, in this embodiment, it includes a first triangular device (arranged on the first head) and a second triangular device (arranged on the second head), wherein:

[0054] The first triangle device includes a triangle bottom plate 1, an upper Zhongshan triangle 11 and a lower Zhongshan triangle 12 are arranged in the middle of the triangle bottom plate 1, and a needle triangle 13 is arranged on both sides of the lower Zhongshan triangle 12. A limited groove 111 is arranged on the top of the upper Zhongshan triangle 11, and a density triangle is arranged on both sides; in this embodiment, the density triangle on the left side of the triangle bottom plate is a movable density triangle 2 (the movable type refers to the density triangle that can only move up and down relatively in the prior art), and the movable density triangle 2 is a quadrilateral structure as a whole, and a compression slope 21 from thin to thick is arranged on the left side, and the right side of the compression slope 21 is a compression plane 22, and a part of the compression slope 21 is also under the elastic auxiliary triangle 3 on the left side.

[0055] by Figure 1 As a reference, the density limit point 31 of the elastic auxiliary triangle 3 is higher than the needle bottom edge 23 of the movable density triangle 2, that is, according to Figure 1As shown by the dotted line in the figure, when knitting rubber bands, the knitting needle starts from the rubber band triangle 4 on the left side, and after being lifted and lowered by the rubber band auxiliary triangle 3, it moves to the right from the density limit point 31. In this process, it passes through the surface of the compression slope 21 and the compression plane 22, thereby pressing the movable density triangle 2 into the triangle bottom plate 1. The knitting needle continues to move from the needle starting triangle 13 on the left side, and after moving along the needle path between the upper and lower Zhongshan triangles 12, it is restricted by the density triangle on the right side and moves from its bottom edge.

[0056] by Figure 2 As shown by the dotted line in the figure, since the movable density cam 2 is not subjected to the pressure of the needle butt at this time, it is in a normal working state, and the knitting needle starts from the needle starting cam 13 on the right side, and after following the needle running channel between the upper and lower Zhongshan cams 12, it passes through the needle running bottom edge 23 of the movable density cam 2 under the restriction of the movable density cam 2 on the left side; as a preferred embodiment, refer to Figure 5 , 9 As shown, a protrusion 24 is further provided below the movable density cam 2, so that a needle passage is formed at the bottom of the movable density cam 2.

[0057] Figure 3 What is shown is a schematic diagram of the distribution of each triangle of the second triangle device. Compared with the triangles of the first triangle device, it only sets the movable density triangle 2 to the right side to meet the requirements of staggered double-sided weaving. The other operating principles are consistent with the first triangle device.

[0058] Figure 4-8 The structure of the movable density cam 2 in the first embodiment is shown, which includes a mounting plate 5, the mounting plate 5 is provided with a slide groove 51, a density triangle seat 6 is provided in the slide groove 51, the movable density cam 2 is provided in the density triangle seat 6, and since the movable density cam 2 needs to have a telescopic function, a cylindrical spring seat 61 is provided in the corresponding position of the density triangle seat 6, and the spring seat 61 needs to have a certain depth to ensure that a reset spring 62 can be provided inside and has sufficient activity space, and the movable density cam 2 can be telescopic relative to the density triangle seat 6, refer to Figure 7 , 8 When the knitting needle butt passes through the compression slope 21 of the movable density cam 2, the movable density cam 2 is pressed into the density cam seat 6, and the return spring 62 is compressed. When the knitting needle butt leaves, the return spring 62 restores the movable density cam 2 to a normal working state.

[0059] The slide groove 51 is used for the density triangle seat 6 to move up and down. The density triangle seat 6 is controlled by a pressure rod and a tension spring. The control method is consistent with the prior art.

[0060] The setting structure of the aforementioned movable density triangle 2 is that the overall thickness of the mounting plate 5 is greater than the commonly used triangular base plate during actual processing; if the triangular base plate and the mounting plate 5 are made into a structure with the same thickness, the weight of the entire triangular base plate will be greatly increased, resulting in an increase in the load when the machine head moves left and right, which is not conducive to production; therefore, the mounting plate 5 can be processed into a structure independent of the triangular base plate, and then the corresponding space is reserved on the triangular base plate, and the mounting plate 5 is directly set in the triangular base plate, and the density triangle seat 6 is restricted in the slide groove 51 by the limit plates 7 on both sides, so that it can only move in the slide groove 51.

[0061] Embodiment 2:

[0062] like Fig.10 As shown, this structure is based on the prior patent of the applicant of this case CN117512864A The improvement made by the double-sided weaving process with two heads running synchronously can also change the density triangle on one side into a movable density triangle consistent with the first embodiment, and the principles of normal weaving and elastic weaving are consistent with the embodiment.

[0063] The above are only specific embodiments of the present utility model. At the same time, all words such as "upper, lower, left, right, middle" involved in the present utility model are for reference only and are not absolutely limiting. Any non-substantial changes made using the present utility model shall be deemed as an infringement of the protection scope of the present utility model.
