DETAILED DESCRIPTION

[0020] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0021] Please refer to Figures 1-5 The utility model provides a technical scheme: cooperate with normal pressure type sinker control mechanism, mainly including brush assembly part 101 and base body part 1, see Figure 1 The base body part 1 is installed on the head, the brush assembly 101 is installed on the base body, and the brush assembly 101 is prior art, can move left and right with control plate 2 and carry out lifting movement, this control mechanism drives normal pressure type sinker to press the action of yarn or loop in the process of forming a circle with the left and right movement of the head.

[0022] See Figure 2 As shown in the figure, it is the structure diagram of base body part 1, control plate 2 is placed in the horizontal slot FA 105 of base body reverse F 103, is pressed by pressing plate 8, the vertical slot FAa 106 and small horizontal slot Fab 107 are set up on the horizontal slot FA 105 on base body 1, vertical slider 7 is placed in vertical slot FAa 106, can be moved freely along vertical slot FAa 106, horizontal slider 6 is placed in small horizontal slot Fab 107, can be moved freely along small horizontal slot Fab 107.

[0023] Base body front Z 104 places left movable triangle 4 and right movable triangle 5, and is connected with two vertical sliders 7 respectively, base body front Z 104 places middle triangle 3, and is connected with horizontal slider 6, base body front Z 104 places needle return triangle 12.

[0024] A control groove 1 22 and a control groove 2 23 are provided on the control board 2. Both the control groove 1 22 and the control groove 2 23 are in a Z shape. A bearing 71 is installed on the vertical slider 7. The bearing 71 is placed in the control groove 1 22 and the control groove 2 23 of the control board 2. When the control board 2 moves left and right, the left movable triangle 4 and the right movable triangle 5 are respectively controlled to move up and down through the "Z"-shaped control groove 1 22 and the control groove 2 23.

[0025] The horizontal slider 6 is locked to the middle screw hole 21 of the control slot 1 22 and the control slot 2 23 of the control board 2, so that it drives the middle triangle 3 to move left and right synchronously with the control board 2.

[0026] A transmission rack 10 is installed on the control board 2, and a gear is installed on the motor 102. The motor 102 controls the transmission rack 10 to move left and right, thereby driving the control board 2 to move left and right. The base 1 is connected to the machine head through the connecting block 9.

[0027] See Figure 3 The figure shows the transfer state. The control panel 2 is in the middle position, which drives the middle cam 3 to the middle position. The left movable cam 4 and the right movable cam 5 are both driven by the control panel 2 to be in a downward pressure state. During transfer, the sinker normally presses down on the stitch. After entering the needle path formed by the left movable cam 4, the right movable cam 5 and the return cam 12, the sinker is pushed to pre-lift and then continue to press. This action is to prevent the yarn from getting caught on the sinker during the previous stitch process, which would affect the next stitch.

[0028] During the needle transfer action, the sinker enters the needle path formed by the middle cam 3 and the return cam 12 and is pushed up. At this time, the brush 101 is in an ascending state to prevent the knitting needle from being deformed by the brush 101 when it comes to high needle transfer action, thereby affecting the normal needle transfer.

[0029] When the needle retreats after the needle transfer is completed, the sinker leaves the middle triangle 3 and forms a needle path 12 with the return needle triangle and continues to automatically press the coil.

[0030] See Figure 4 As shown, it is a schematic diagram of the right-moving circle state of the machine head. The control board 2 moves left, driving the middle triangle 3 to move left. The left movable triangle 4 is driven by the control board 2 to be in an upward state, and the right movable triangle 5 is driven by the control board 2 to be in a downward state.

[0031] When forming a loop, the right movable cam 5 pushes the sinker to pre-lift it and then continue to press it. During the loop forming process, the sinker is outside the range of the middle cam 3, so it always presses the coil to prevent the coil from being brought up during the rising process of the knitting needle and causing floating yarn. At this time, the brush 101 is in a descending state, and when the knitting needle rises, the needle tongue is brushed open by the brush 101 and the thread is hooked.

[0032] When the needle is retracted after the loop is formed, the sinker enters the needle path formed by the middle cam 3 and the needle retraction cam 12, the sinker is pushed to lift up, the loop is smoothly dropped, and the sinker automatically presses down the loop after the sinker is separated from the needle path formed by the middle cam 3 and the needle retraction cam 12.

[0033] See Figure 5 As shown in the left row of the machine head weaving state schematic diagram, the control plate moves right, drives the middle cam 3 to move right, the left movable cam 4 is driven by the control plate 2 to be in the depressed state, the right movable cam 5 is driven by the control plate 2 to be in the lifting state, and the action of the sinker when the loop is formed is the same as the above-mentioned right row of the machine head loop forming state.

[0034] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to the embodiments without departing from the principles and spirits of the present application, the scope of the present application is defined by the appended claims and their equivalents.
