Description

Technical Field

[0001] The utility model belongs to the technical field of textile machinery, and more specifically, particularly relates to a sewing platform structure. Background Art

[0002] In textile processing, sewing machines are a common textile processing tool. When using sewing machines, workers who can operate the stitches are often required to synchronously drive the needle to work while controlling the sewing position and movement speed of the fabric, and then adjust the stitch interval and sewing quality.

[0003] However, in actual operation, textile workers can only observe the sewing situation of the needle and thread of the sewing machine head from the direction of material feeding when using the sewing machine, so textile workers often only press the fabric in the needle feeding direction and push it under the sewing machine head, while ignoring the fabric in the needle outlet direction, causing the fabric in the needle outlet direction to easily curl and fold. If the sewing area is long, the fabric in the front is easily squeezed and rolled back, which may not only block the line of sight but also touch the needle and thread, affecting sewing efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a sewing platform structure is provided to achieve a purpose with more practical value. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a sewing platform structure to solve the problem that the fabric in the needle exit direction is easily curled and folded during sewing.

[0006] The purpose and function of the sewing platform structure of the utility model are achieved by the following specific technical means:

[0007] A sewing platform structure comprises a mounting plate, a protective plate and a needle plate, wherein a swivel seat is arranged on the mounting plate, a swing arm is hinged on the swivel seat, a pressure rod is passed through the end of the swing arm, a traction wheel is arranged at one end of the pressure rod, and a transmission sleeve is arranged at the other end, a motor is also mounted on the mounting plate, a friction sleeve is arranged at the output end of the motor, a torsion spring is arranged between the swing arm and the swivel seat so that the transmission sleeve abuts against the friction sleeve, and the traction wheel corresponds to the front end position of the needle plate.

[0008] Furthermore, the other end of the swing arm is connected to a rotating frame, the rotating frame is sleeved on the central axis of the rotating seat, the torsion spring is sleeved on the central axis, one end of the torsion spring abuts on the rotating frame, and the other end abuts on the mounting plate.

[0009] Furthermore, a bearing is provided between the pressure rod and the swing arm.

[0010] Furthermore, a secondary rod is provided through the middle section of the swing arm, and a limiting wheel corresponding to the traction wheel is provided at one end of the secondary rod.

[0011] Furthermore, a balancing block is arranged at the other end of the auxiliary rod.

[0012] Furthermore, a limit seat is arranged on the protective plate, a baffle is installed on the limit seat, and one end of the baffle is vertically buckled on one side of the sewing machine head.

[0013] Furthermore, a movable groove is formed on the baffle plate, and a bolt is provided on the baffle plate, and the bolt passes through the movable groove and is threadedly connected to the limiting seat.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] Through the setting of the swing arm, the fabric after passing through the sewing machine head needle is guided by the traction wheel at the front end of the swing arm. The traction wheel is powered by the motor and transmitted to the traction wheel through friction, so that the traction wheel rotates and pulls after contacting the fabric, avoiding the fabric from rolling back and reducing the impact of fabric curling on the sewing area.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Example:

[0025] As attached Figure 1 To Attachment Figure 3 As shown:

[0026] The utility model provides a sewing platform structure, including a mounting plate 1, a protective plate 2 and a needle plate 3. In the prior art, a tooth frame, a shuttle, a feeding tooth, etc. are arranged in the mounting plate 1. The protective plate 2 on the mounting plate 1 is detachable and used to observe and repair the components inside the mounting plate 1, and the needle plate 3 provides holes and support for needle threading and sewing.

[0027] In this embodiment, a swivel seat 7 is provided on the mounting plate 1, and a swing arm 8 is hinged on the swivel seat 7. A pressure rod 83 is passed through the end of the swing arm 8, and a traction wheel 9 is provided at one end of the pressure rod 83. After the cloth passes through the needle plate 3 and the sewing machine head 4, it contacts the traction wheel 9, and a transmission sleeve 85 is provided at the other end of the pressure rod 83. A motor 10 is also installed on the mounting plate 1, and a friction sleeve 11 is provided at the output end of the motor 10. A torsion spring 82 is provided between the swing arm 8 and the swivel seat 7 so that the transmission sleeve 85 abuts against the friction sleeve 11. The torsion spring 82 still enables the traction wheel 9 to press the cloth. When the motor 10 rotates, the friction force between the friction sleeve 11 and the transmission sleeve 85 transmits the rotational power to the traction wheel 9, and a bearing 86 is clamped between the pressure rod 83 and the swing arm 8 to reduce the loss of power transmission.

[0028] The traction wheel 9 corresponds to the front end position of the needle plate 3. After the cloth contacts the traction wheel 9, the rotation of the traction wheel 9 causes the cloth to continue to be pulled and moved from under the traction wheel 9, while effectively avoiding the winding of the cloth.

[0029] like Figure 3 As shown, the other end of the swing arm 8 is connected to a rotating frame 81, and the rotating frame 81 is sleeved on the central axis of the rotating seat 7. The torsion spring 82 is sleeved on the central axis. One end of the torsion spring 82 abuts on the rotating frame 81, and the other end abuts on the mounting plate 1. Both sides of the rotating frame 81 contact the rotating seat 7 to increase the stability of the swing of the swing arm 8. The torsion spring 82 squeezes the rotating frame 81 to provide a torque for the swing arm 8 to swing downward.

[0030] Among them, a secondary rod 84 is also passed through the middle section of the swing arm 8, and a limiting wheel 91 corresponding to the traction wheel 9 is set at one end of the secondary rod 84. When the swing arm 8 is buckled, the distance between the limiting wheel 91 and the needle plate 3 is greater than the distance between the traction wheel 9 and the needle plate 3. The traction wheel 9 pulls the cloth backward, and the limiting wheel 91 can also be placed above the cloth, extending the length of the cloth to prevent it from rolling up; and a balancing block 12 is set at the other end of the secondary rod 84, which increases the stability of the limiting wheel 91. At the same time, the position of the limiting wheel 91 can be adjusted by moving the secondary rod 84.

[0031] Among them, a limiting seat 5 is arranged on the protective plate 2, and a baffle 6 is installed on the limiting seat 5. One end of the baffle 6 is vertically buckled on one side of the sewing machine head 4. The setting of the baffle 6 can block the cloth and prevent the position from shifting, so that the sewing position of the cloth is uniform. A movable groove is opened on the baffle 6, and a bolt is arranged on the baffle 6. The bolt passes through the movable groove and is threadedly connected with the limiting seat 5, so that the position of the baffle 6 can be adjusted.

[0032] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
