DETAILED DESCRIPTION

[0040] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The embodiments of the present invention include but are not limited to the following embodiments.

[0041] like Figure 1-7As shown, the hand-sewing imitation seaming machine provided by the present invention comprises: a seaming machine body 1 for sewing socks, two guide plates 2 are provided at the feeding end of the seaming machine body 1, and a feeding mechanism 3 is provided below the guide plate 2. The feeding mechanism 3 is used to feed the socks entering between the two guide plates 2 into the seaming machine body 1, and the seaming machine body 1 performs seaming processing on the socks. The structure of the seaming machine body 1 can be produced by the existing disclosed technology, and it will not be repeated here. An auxiliary feeding mechanism is provided on one side of the seaming machine body 1. The auxiliary feeding mechanism is arranged at the feeding end of the seaming machine body 1, that is, close to the guide plate 2. The auxiliary feeding mechanism is used to assist the operator to place the socks so that the socks can be placed in the guide plate 2 when entering the guide plate 2. , the stitching length of the socks is consistent, and the product quality is better; the auxiliary feeding mechanism includes a feeding plate 4, on which a position positioning component, a horizontal conveying component, an angle adjustment component and an intermediate transmission component are provided; the position positioning component includes a positioning plate 38 embedded in the top of the far end of the feeding plate 4, and a plurality of scales are horizontally arranged on the positioning plate 38. The scales are used to confirm the horizontal placement of the socks, and the right ends (non-sewing ends) of all socks are always aligned with a certain scale line of the scale. This operation is more suitable for unskilled workers and has better operability; the horizontal conveying component includes a horizontal conveyor 5 installed on the feeding plate 4 and two pressure rods 6 arranged above the horizontal conveyor 5, and the front of the pressure rod 6 The end is tilted to facilitate the socks to be fed into the space between the horizontal conveyor 5 and the two pressure rods 6. The flat socks are pushed horizontally from the left side along a certain scale line of the ruler into the space between the horizontal conveyor 5 and the two pressure rods 6. The horizontal conveyor 5 and the pressure rod 6 press the socks tightly and drive the socks to move toward the side close to the guide plate 2. The conveyor belt of the horizontal conveyor 5 is provided with a protrusion to increase the friction force and facilitate the movement of the socks. The angle adjustment component includes a special-shaped plate 7 installed on one side of the feed plate 4. The special-shaped plate 7 is provided with a guide surface that smoothly transitions from horizontal to vertical. The pressure rod 6 on the side close to the special-shaped plate 7 maintains a distance of 5-8mm from the edge of the special-shaped plate 7. The distance can be adjusted according to the thickness and material of the socks. In the process of the socks being transported by the horizontal conveyor 5, the side of the socks that needs to be sewn (the side close to the special-shaped plate 7) moves along the special-shaped plate 7, and the end of the sock slides along the special-shaped plate 7, and is squeezed by the guide surface of the special-shaped plate 7 and the pressure rod 6, so that the end of the sock and the rest of the sock are bent 90 degrees. The bending process is a gradual process, and the whole process is completed before entering the intermediate transmission component. Therefore, an inner clamping plate 37 is provided on one side of the special-shaped plate 7, and the inner clamping plate 37 is connected to the pressure rod 6 close to the side of the guide plate 7. When the bending angle of the socks becomes 80-85, the socks enter between the special-shaped plate 7 and the inner clamping plate 37, so that the bent part of the socks moves along the gap between the special-shaped plate 7 and the inner clamping plate 37;The intermediate transmission component includes a vertical conveyor group 8, which is located above the horizontal conveyor 5 and the feeding mechanism 3. There should be a conveying overlap interval between the vertical conveyor group 8 and the horizontal conveyor 5 and the feeding mechanism 3 to ensure that the socks can be transferred and transported normally. The vertical conveyor group 8 is used to transport the socks transmitted by the horizontal conveyor component to the feeding mechanism 3 (between the guide plates 2). The vertical conveyor group 8 includes a vertically installed left vertical conveyor 19 and a right vertical conveyor 20. The left vertical conveyor 19 and the right vertical conveyor 20 are installed on a frame 21, and the frame 21 is connected to the seam machine body 1. The left vertical conveyor 19 and the right vertical conveyor 20 are installed with a certain distance between the frame 21, which is used to clamp the bent end of the socks. The socks move on the horizontal conveyor 5, and the bent end thereof passes through the special-shaped plate 7 and the inner clamp The socks are fed into the left vertical conveyor 19 and the right vertical conveyor 20 between the plates 37, and then the socks are clamped by the left vertical conveyor 19 and the right vertical conveyor 20 and move to the side close to the guide plate 2. In this process, after the socks move to the area above the feeding plate 4, the socks are turned vertically as a whole, and then the socks are fed between the two guide plates 2, and the middle and lower parts of the socks enter the feeding mechanism 3 until the socks are completely fed into the feeding mechanism 3, and the upper end of the socks is separated from the left vertical conveyor 19 and the right vertical conveyor 20, and then the feeding mechanism 3 can feed the socks into the sewing machine body 1 for processing. Since the non-sewing end (bottom end) of the socks is bent, the height of the bottom end can be kept consistent, so in batch processing, the sewing height of the socks is consistent, so that the length of the socks is more consistent, thereby improving product quality. ;

[0042] By setting up a feeding plate 4 including a positioning component, a horizontal conveying component, an angle adjustment component and an intermediate transmission component, the socks are positioned by the positioning component, and the horizontal conveying component, the angle adjustment component and the intermediate transmission component are used for conveying and the angle conversion, so that the socks can be processed neatly, which is more convenient for novice operators to operate and can improve the product processing quality.

The top of the T-shaped rod 12 is connected to the first linkage shaft 15, and the first linkage shaft 15, the second linkage shaft 16 and the third linkage shaft 17 are connected in sequence through a connecting rod structure. A hysteresis shaft 18 is installed on the third linkage shaft 17. When the socks are sent under the pressure rod 6 and transmitted to the rear, when the socks pass under the roller 13, the roller 13 is lifted, thereby raising the T-shaped rod 12, thereby driving the first linkage shaft 15 to rotate counterclockwise ( Figure 4 ), the first linkage shaft 15 rotates counterclockwise to drive the second linkage shaft 16 to rotate clockwise, and the second linkage shaft 16 rotates clockwise to drive the third linkage shaft 17 to rotate counterclockwise, thereby lowering the height of the hysteresis shaft 18, pressing the part of the socks that has not yet entered between the horizontal conveyor 5 and the pressure rod 6, delaying the movement of this part, and thereby stretching the socks flat.

[0045] By providing a flattening component 9 including a fixing seat 11, a T-shaped rod 12, a roller 13, a first linkage shaft 15, a second linkage shaft 16, a third linkage shaft 17 and a hysteresis shaft 18, the socks entering the horizontal conveying assembly 8 can be flattened.

[0046] Embodiment 3:

[0047] like Figure 4-5 As shown, a guide rod 14 is installed at the end of the roller 13, and the guide rod 14 passes through the fixing seat 11. Since the guide rod 14 can only move up and down, the T-shaped rod 12 can be prevented from axially rotating.

[0048] By installing the guide rod 14 at the end of the roller 13, the T-shaped rod 12 can be conveniently guided.

[0049] Embodiment 4:

When no socks pass under the roller 13, the T-shaped rod 12 is lowered under the action of the compressed reset spring 32, thereby driving the roller 13 to descend, which is conducive to the lowering and resetting of the roller 13.

[0051] By providing the mounting groove 31 and the return spring 32 and utilizing the elasticity of the return spring 32 , the roller 13 can be conveniently driven to descend and return to its original position.

Therefore, the left vertical conveyor 19 can adjust the angle, and the bolts 22 connected to the right vertical conveyor 20 are fastened with two nuts. One of the two connected bolts 22 is fastened with two nuts and the other with one nut, and a compression spring 24 is installed on the bolt 22. The mounting hole close to the right vertical conveyor 20 is a rectangular hole 23, which makes it easy to adjust the position of the right vertical conveyor 20. The compression spring 24 allows the right vertical conveyor 20 to rotate slightly in the horizontal plane, so that the angle between the left vertical conveyor 19 and the right vertical conveyor 20 is variable, which is more suitable for socks to squeeze in between the left vertical conveyor 19 and the right vertical conveyor 20, and is more suitable for the transportation of socks.

[0054] By providing the compression spring 24, the socks can be squeezed more easily between the left vertical conveyor 19 and the right vertical conveyor 20, which can be more suitable for conveying the socks.

[0055] Embodiment 6:
