All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0034] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a fabric positioning device for a computerized pattern making machine, comprising:
[0035] The base 1 is equipped with a fabric positioning mechanism. It should be noted that the fabric positioning mechanism facilitates quick and easy positioning of the fabric. Moreover, the fabric positioning mechanism has good stability after assembly and will not shift.
[0036] The fabric positioning mechanism includes a mounting base 3, a horizontal plate 4, a vertical plate 5, an L-shaped block 6, a lead screw 7, a main plate 8, a rotating shaft 9, an auxiliary plate 10, and a pressing block 11;
[0037] The bottom of the horizontal plate 4 is fixedly connected to the vertical plate 5. The L-shaped block 6 is fixedly installed on the bottom of the mounting base 3. The screw rod 7 is rotatably installed on the mounting base 3. The screw rod 7 is threadedly connected to the horizontal plate 4. The main plate 8 is fixedly connected to the horizontal plate 4. It should be noted that two main plates 8 are installed on each horizontal plate 4.
[0038] The rotating shaft 9 is rotatably mounted on the main board 8, and the auxiliary plate 10 is fixedly connected to the rotating shaft 9 and the clamping block 11.
[0039] Using the fabric positioning mechanism described above, the L-shaped block 6 is first moved vertically into the L-shaped groove 13, and then the mounting base 3 is pushed horizontally to make the L-shaped block 6 snap into the L-shaped groove 13. The position of the pressing block 11 is adjusted, and then the screw 7 is rotated to make the anti-slip pad 12 move down to press and position the fabric on the base 1. The anti-slip pads 12 on the four pressing blocks 11 press the four corners of the fabric onto the base 1. That is, only by rotating the screw 7, the fabric can be quickly positioned. During this process, the horizontal plate 4 drives the vertical plate 5 to move down, and the bottom of the vertical plate 5 will also move into the L-shaped groove 13. The vertical plate 5 can limit the L-shaped block 6 laterally, which can ensure the stability of the fabric positioning mechanism assembled on the base 1 and prevent displacement.
[0040] Specifically, the base 1 has a pattern sewing machine body 2 installed on top. It should be noted that the pattern sewing machine body 2 sews patterns onto the positioned fabric. The specific structure of the pattern sewing machine body 2 is existing technology and will not be described in detail here.
[0041] Specifically, the top of the base 1 has multiple L-shaped grooves 13, and the vertical plate 5 and the L-shaped block 6 are engaged with the same L-shaped groove 13. The side of the vertical plate 5 is in contact with the L-shaped block 6. It should be noted that this can limit the position of the mounting base 3.
[0042] Specifically, the bottom of the mounting base 3 is in contact with the base 1, and a rectangular hole is provided on the front side of the mounting base 3. The rectangular hole is passed through the front sides of the horizontal plate 4. A vertical hole is provided on the inner wall of the bottom of the rectangular hole. The vertical plate 5 is vertically slidably installed in the vertical hole. It should be noted that this allows the vertical plate 5 to move stably in the vertical direction.
[0043] Specifically, the bottom of the pressing block 11 is fixedly equipped with an anti-slip pad 12, which is to ensure the stability of the fabric after it is pressed.
[0044] Specifically, a screw groove is provided at the top of the horizontal plate 4, and the screw rod 7 is threadedly connected to the screw groove. It should be noted that when the screw rod 7 rotates, the horizontal plate 4 can move vertically.
[0045] Specifically, a damping washer is installed on the motherboard 8, and the rotating shaft 9 abuts against the inner side of the damping washer. It should be noted that the damping washer can provide a large friction force. When the rotating shaft 9 rotates to a certain position, the friction force provided by the damping washer can keep the rotating shaft 9 stable at that position.
[0046] Working principle:
[0047] S1: First, move the L-shaped block 6 vertically into the L-shaped groove 13, then push the mounting base 3 horizontally so that the L-shaped block 6 is inserted into the L-shaped groove 13. Then rotate the auxiliary plate 10 to adjust the position of the clamping block 11.
[0048] S2: Next, rotate the lead screw 7. When the lead screw 7 rotates, the horizontal plate 4 will move downward. The horizontal plate 4 will drive the main plate 8 to move downward. The main plate 8 will drive the auxiliary plate 10 to move downward through the rotating shaft 9. The auxiliary plate 10 will drive the pressing block 11 to move downward. The pressing block 11 will drive the anti-slip pad 12 to move downward. In this way, the anti-slip pad 12 can press and position the fabric on the base 1. The anti-slip pads 12 on the four pressing blocks 11 will press the four corners of the fabric onto the base 1 respectively.
[0049] S3: Simply rotate the lead screw 7 to quickly position the fabric. During this process, the horizontal plate 4 moves the vertical plate 5 downward, and the bottom of the vertical plate 5 moves into the L-shaped groove 13. The vertical plate 5 can laterally limit the L-shaped block 6, which can ensure the stability of the fabric positioning mechanism on the base 1 and prevent displacement. It is also convenient to operate.
[0050] The above provides a detailed description of a fabric positioning device for a computerized pattern making machine. Specific embodiments have been used to illustrate the principles and implementation methods of this invention. These embodiments are merely illustrative and are intended to aid in understanding the method and core concepts of this invention. It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of this invention.
