Description

Technical Field

[0001] The utility model relates to the field of glove knitting machines, in particular to a density triangle structure 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] In view of the above reasons, the inventor conducted further research and developed a triangular structure of glove machine density, which resulted in the present invention. Utility Model Content

[0007] The utility model aims to provide a triangular structure of glove knitting machine density, which can avoid the breakage of elastic thread when the glove knitting machine is double-sided knitting, and improve the production efficiency at the same time.

[0008] A glove machine density triangle structure, comprising

[0009] A mounting plate is provided in the mounting plate, a slide groove is provided in the slide groove, a density triangle seat is provided in the density triangle seat, and a density triangle is provided in the density triangle seat; a part of the density triangle is located in the density triangle seat, and a part is located outside the density triangle seat, and the part located outside the density triangle seat includes a compression slope and a compression plane, and the sides of the compression slope and the compression plane together constitute the needle bottom edge; a reset member is provided between the density triangle and the density triangle seat, when the compression slope and the compression plane are subjected to the pressure of the needle butt, the density triangle moves toward the density triangle seat, and the reset member is compressed; when the needle butt leaves the compression slope and the compression plane, the reset member is restored.

[0010] The "compression plane" here does not refer to an absolutely flat and smooth surface, but is mainly used to distinguish it from a compression slope;

[0011] After actual production tests, the entire density triangle is designed as a passive avoidance structure, which can solve the problems existing in the prior art. When knitting elastic bands, after the elastic band triangle is started, the butt of the knitting needle is allowed to pass through the compression slope and compression plane of the density triangle to relatively compress the entire density triangle, so that the knitting needle can pass through the surface of the density triangle without being controlled by the downward pressure amplitude; and when the butt of the knitting needle comes back from the other side, it will pass through the bottom edge of the needle running of the density triangle.

[0012] Furthermore, the reset element is an elastic sheet or a reset spring.

[0013] 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.

[0014] The needle movement channel can make the needle movement more stable when the density triangle is working.

[0015] Furthermore, the return spring is arranged in the spring seat, and the spring seat is protrudingly arranged on the density triangle seat.

[0016] 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.

[0017] Furthermore, the mounting plate can be arranged on the triangular bottom plate of the glove machine, the density triangular seat is arranged in the mounting plate, and the thickness of the mounting plate is greater than the thickness of the triangular bottom plate.

[0018] 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.

[0019] Furthermore, when the mounting plate is set on the triangular bottom plate, the density limit point of the elastic auxiliary triangle on the triangular bottom plate is higher than the needle bottom edge of the density triangle. The butt of the knitting needle passes through the limit point and then passes through the compression slope, so that the density triangle retracts relative to the triangular bottom plate.

[0020] The density limit point of the above-mentioned elastic auxiliary triangle and the needle bottom edge of the density triangle determine the downward pressure amplitude during elastic knitting and normal knitting mentioned in the background technology (i.e. the amplitude of the needle pulling the thread downward after hooking the thread). Here, "the density limit point is higher than the needle bottom edge of the density triangle", that is, the downward pressure amplitude of the elastic auxiliary triangle is smaller than the downward pressure amplitude of the density triangle.

[0021] Furthermore, the density limit point of the elastic auxiliary triangle is its lowest point.

[0022] When knitting rubber bands, the needle starts from the rubber band triangle, follows the needle path between the rubber band auxiliary triangle and the rubber band triangle, and then passes through the density limit point, which is the downward pressure amplitude of the rubber band knitting.

[0023] After adopting the above scheme, the utility model has the following advantages compared with the prior art:

[0024] Compared with the solutions in the prior art, it does not require the density triangle to be set as an active avoidance structure, nor does it require the needle starting direction of the elastic triangle to be changed or the order of eating the elastic thread. It has a simple structure, low production and use costs, and can also ensure production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0043] In the following embodiments, the cam device (machine head) actually moves in the horizontal direction, 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.

[0044] Embodiment 1:

[0045] 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".

[0046] like Figure 1 , 3 As shown, in this embodiment, the density triangle structure can be arranged on the first triangle device (arranged on the first head) and the second triangle device (arranged on the second head), wherein:

[0047] 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.

[0048] 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 1 As 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.

[0049] 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.

[0050] 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.

[0051] Figure 4-8The present invention shows a density triangle structure of a glove machine that can be applied to the first embodiment, including a mounting plate 5, the mounting plate 5 is provided with a slide groove 51, a density triangle seat 6 is arranged in the slide groove 51, and a movable density triangle 2 is arranged in the density triangle seat 6. Since the movable density triangle 2 needs to have a telescopic function, a cylindrical spring seat 61 is arranged in the corresponding position of the density triangle seat 6. The spring seat 61 needs to have a certain depth to ensure that a reset spring 62 can be arranged inside and has sufficient activity space. The movable density triangle 2 can be telescopic relative to the density triangle seat 6. 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.

[0052] 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.

[0053] 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.

[0054] Embodiment 2:

[0055] like Fig.10 As shown, the structure is an improvement based on the double-sided weaving process with two heads running synchronously in the prior patent CN117512864A of the applicant of this case. The density triangle on one side can also be changed into a movable density triangle consistent with the first embodiment. The principles of normal weaving and elastic weaving are consistent with the embodiment.

[0056] 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.
