Description

Technical Field

[0001] The utility model relates to the technical field of quilting machines, in particular to a quilt clamping device for a quilting machine. Background Art

[0002] Before using a quilting machine to lay the fibers, a clamp is needed to clamp the fibers and the upper and lower layers of the quilt cover to facilitate subsequent laying processing.

[0003] Usually, ordinary wide clamps are used to clamp the fibers and the quilt cover. The upper and lower layers of the quilt cover and the middle layer of fibers are clamped by multiple wide clamps and then sent to a laying machine for laying. Before clamping, workers are required to manually pull the quilt cover flat. However, due to the large number of clamping locations and the order of clamping, it is difficult for workers to manually pull the quilt cover flat. Therefore, a quilt clamping device for a quilting machine is proposed to solve the above-mentioned problems. Utility Model Content

[0008] A quilt clamping device for a quilting machine comprises a clamp and a quilt pulling component, wherein the quilt pulling component is arranged inside and on one side of the clamp;

[0009] The quilt pulling component comprises a spring and a clamping block, one side of the clamping block is fixedly connected with a slider, and the other side of the clamping block is fixedly connected with a protrusion, and the elastic potential energy of the spring enables the clamping block to move, thereby realizing the quilt pulling function.

[0010] As a preferred technical solution of the utility model, the clamp is composed of two oppositely placed clamping plates, namely an upper clamping plate and a lower clamping plate. The opposite surfaces of the two clamping plates are provided with fixing grooves, and a torsion spring is fixedly connected between the two clamping plates.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a quilt clamping device for a quilting machine, which has the following beneficial effects:

[0016] The quilt clamping device of the quilting machine realizes normal clamping of the quilt cover by the clamp through the torsion spring. When the quilt cover is clamped by the clamp on all sides, the electromagnets are de-energized.

[0025] See also Figure 1-4 A quilt clamping device for a quilting machine comprises a clamp 1 and a quilt pulling component, wherein the quilt pulling component is arranged inside and on one side of the clamp 1;

[0026] The quilt pulling assembly includes a spring 6 and a clamping block 4. A slider 401 is fixedly connected to one side of the clamping block 4, and a protrusion 402 is fixedly connected to the other side. The elastic potential energy of the spring 6 enables the clamping block 4 to move, thereby realizing the quilt pulling function.

[0027] As a preferred technical solution of the utility model, the clamp 1 consists of two oppositely placed clamps, namely an upper clamp and a lower clamp, and fixing grooves 2 are provided on the opposite surfaces of the two clamps, and a torsion spring 3 is fixedly connected between the two clamps. The torsion spring 3 is used to control the clamping state between the upper clamp and the lower clamp of the clamp 1, so that the clamp 1 clamps the quilt surface under the action of the torsion spring 3.

[0028] It should be noted that the torsion spring 3 can store and release angular energy or statically fix a device by rotating the force arm around the central axis of the spring body, so as to achieve the clamping of the quilt by the clamp 1.

[0029] As a preferred technical solution of the utility model, the fixed ends of the torsion spring 3 are respectively inserted into the fixing grooves 2 of the two clamps, and the fixed ends of the torsion spring 3 are supported in the fixing grooves 2 so that it can stably control the opening and closing of the clamp 1. The torsion spring 3 is fixedly connected to the limiting rings on both sides, and the limiting rings are movably connected to the clamp, and the limiting rings limit the two ends of the torsion spring 3.

[0030] It should be noted that the limiting ring is used for the displacement of the fiber torsion spring 3 but does not affect its rotational torsion.

[0031] As a preferred technical solution of the utility model, a slide groove 7 is opened on the opposite side of the clamp 1, and the inside of the slide groove 7 is fixedly connected to the bottom of the spring 6 near one end of the torsion spring 3, and the top of the spring 6 is fixedly connected to the slider 401. The slider 401 slides on the slide groove 7 under the action of the spring 6. After the slider 401 passes through the slide groove 7, it is fixedly connected to the clamping block 4. The spring 6 drives the slider 401 along the slide groove 7 so that the clamping block 4 moves to realize the quilt pulling function.

[0032] As a preferred technical solution of the utility model, a magnetic material is provided on the top of the slider 401, and a small groove is opened inside the clamp 1 near the top of the slider 401, and an electromagnet 5 is placed in the small groove. When the electromagnet 5 is energized, it can attract the magnetic material on the top of the slider 401. When the electromagnet 5 is powered on, the magnetism disappears, and the slider 401 starts to move under the elastic potential energy of the spring 6. A total of six arrays of protrusions 402 are provided and distributed on one side of the clamp 4.

[0033] It should be noted that when the electromagnet 5 is energized and magnetically attracted to the slider 401, the spring 6 is in a pulling state and has a certain elastic potential energy. The protrusion 402 is used to change the surface-to-surface contact to multiple-point contact with the quilt surface, which is more conducive to pulling the quilt surface.

[0034] Beneficial effects:

[0035] The quilt clamping device of the quilting machine realizes normal clamping of the quilt cover by the clamp 1 through the torsion spring 3. When the quilt cover is clamped by the clamp 1 on all sides, the electromagnet 5 is uniformly powered off. Under the action of the elastic potential energy of the spring 6, the slider 401 moves along the slide groove 7 toward the torsion spring 3, so that the clamping block 4 and the protrusion 402 clamp the quilt and move in the direction of the torsion spring 3, thereby realizing the overall pulling of the quilt cover and making the quilt cover smoother. At the same time, the design of the protrusion 402 on one side of the clamping block 4 changes the surface contact to multiple points contact with the quilt cover, which is more conducive to pulling the quilt cover.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
