Description

Technical Field

[0001] The utility model relates to the technical field of fabric processing, and particularly relates to a multi-needle quilting and embroidering machine. Background Art

[0002] A multi-needle quilting and embroidering machine is a textile machine for sewing on the surface of fabric.

[0003] When the multi-needle quilting and embroidering machine is working, the fabric is placed on the surface of the workbench, and during the process of processing the fabric, it is necessary to ensure the flatness of the fabric surface. For example, in the patent with the application number 202121428531.2 and the name of the quilting and embroidering machine fabric edge positioning device, the electric push rod drives the first clamping plate and the second clamping plate to descend and press against the fabric, so as to position the fabric edge.

[0004] Although the method of directly pressing down by the clamping plate can ensure that the fabric does not move during the processing, the fabric cannot be guaranteed to be in a flat and wrinkle-free state before being positioned by the clamping plate. Therefore, we propose a multi-needle quilting and embroidering machine. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a multi-needle quilting and embroidering machine to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A multi-needle quilting and embroidering machine, comprising:

The bottom end of the connecting frame is fixedly connected with a connecting rod, and the top ends of multiple connecting rods are respectively fixedly connected with the top ends of multiple inverted U-shaped frames. A lifting mechanism is arranged at the top end of the connecting frame.

[0010] Preferably, the lifting mechanism includes a telescopic cylinder. The top end of the workbench is fixedly connected with a support plate, the top end of the support plate is fixedly connected with a top plate, the telescopic cylinder is installed at the bottom end of the top plate, and the middle part of the inner wall of the connecting frame is fixedly connected with a fixing plate.

One end of the torsion spring is connected with the inner wall of the activity cavity, and the other end of the torsion spring is connected with the outer wall of the rotating shaft. A limiting mechanism is arranged inside the inverted U-shaped frame.

[0013] Preferably, the limiting mechanism includes a limiting rod. Both ends of the limiting rod are fixedly connected with the inner wall of the inverted U-shaped frame. One end of the extrusion rotating rod is fixedly connected with a connecting block.

[0014] The technical effects and advantages of the present utility model:

[0015] By using the arrangement of the inverted U-shaped frame and the extrusion rotating rod, after the fabric is placed flat on the top of the workbench, the inverted U-shaped frame descends to drive the extrusion rotating rod to descend.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides a multi-needle quilting machine as Figures 1-3 shown, which includes a workbench 101 and a cloth pressing mechanism. Above the workbench 101, a multi-needle base 102 is provided. A slide rail is provided at the bottom end of the top plate 306, and a slide seat is provided at the top end of the multi-needle base 102. The movement of the slide seat on the slide rail can drive the multi-needle base 102 to move for work.

[0022] In a preferred embodiment, the cloth pressing mechanism is arranged at the corner above the workbench 101. The cloth pressing mechanism includes an inverted U-shaped frame 201 arranged in a lifting manner. An extrusion rotating rod 202 is rotatably connected inside the inverted U-shaped frame 201. The extrusion rotating rod 202 is arranged obliquely. An extrusion mechanism is arranged between the extrusion rotating rod 202 and the inverted U-shaped frame 201. After the cloth is placed flat on the top end of the workbench 101, the inverted U-shaped frame 201 descends to drive the extrusion rotating rod 202 to descend. The inclined extrusion rotating rod 202 descends until it abuts against the top end of the cloth. Then the inverted U-shaped frame 201 continues to descend. At this time, the extrusion rotating rod 202 can rotate inside the inverted U-shaped frame 201, and the rotation angle is outward. As a result, the four corners of the cloth will be pulled outward along with the rotation of the extrusion rotating rod 202, so that the wrinkles on the surface of the cloth can be removed, and the cloth can be processed more smoothly, improving the stability and processing quality of cloth processing. Moreover, the end of the extrusion rotating rod 202 in contact with the cloth is arranged in an arc shape, so that the extrusion rotating rod 202 will not damage the cloth when extruding the cloth.

[0023] Among them, a connection frame 302 is provided above the workbench 101. The bottom end of the connection frame 302 is fixedly connected with a connecting rod 301. The top ends of multiple connecting rods 301 are respectively fixedly connected with the top ends of multiple inverted U-shaped frames 201. A lifting mechanism is arranged at the top end of the connection frame 302. Through the connection of the connection frame 302 and the connecting rod 301, multiple inverted U-shaped frames 201 can be lifted simultaneously, so that the cloth pressing mechanism works simultaneously, and only one driving source is needed, improving the convenience of the work of the cloth pressing mechanism.

[0024] Among them, the lifting mechanism includes a telescopic cylinder 304, a support plate 305 is fixedly connected to the top of the workbench 101, a top plate 306 is fixedly connected to the top of the support plate 305, the telescopic cylinder 304 is installed at the bottom of the top plate 306, and a fixed plate 303 is fixedly connected to the middle of the inner wall of the connecting frame 302. The output end of the telescopic cylinder 304 is transmission-connected to the top of the fixed plate 303. The fixed plate 303 can be driven to be lifted and lowered by the operation of the telescopic cylinder 304, thereby driving the connecting frame 302 to be lifted and lowered. Then, under the connection of the connecting rod 301, the cloth pressing mechanism can stably perform the lifting work. The telescopic cylinder 304 is electrically connected to the external power supply through an external switch, which is convenient for the operator to control the telescopic cylinder 304, thereby improving the safety and convenience of the operation of the telescopic cylinder 304. The telescopic cylinder 304 can work stably through the connection between the support plate 305 and the top plate 306.

[0025] Among them, both sides of the extrusion rotating rod 202 are fixedly connected with the rotating shaft 402, the inner wall of the inverted U-shaped frame 201 is symmetrically provided with rotating holes 401, the outer walls of the two rotating shafts 402 are rotatably connected to the inner walls of the two rotating holes 401 respectively, and the extrusion mechanism is arranged on the outer wall of the rotating shaft 402, and rotates in the rotating hole 401 through the rotating shaft 402, so that the extrusion rotating rod 202 can stably rotate in the inverted U-shaped frame 201, thereby improving the working stability of the cloth pressing mechanism.

[0026] The squeezing mechanism includes a torsion spring 502, an active cavity 501 is provided on the inner wall of the rotating hole 401, the torsion spring 502 is arranged inside the active cavity 501, the torsion spring 502 is sleeved on the outer wall of the rotating shaft 402, one end of the torsion spring 502 is connected to the inner wall of the active cavity 501, and the other end of the torsion spring 502 is connected to the outer wall of the rotating shaft 402. A limiting mechanism is arranged inside the inverted U-shaped frame 201. Through the setting of the torsion spring 502, the inverted U-shaped frame 201 is lowered to drive the squeezing rotating rod 202 to lower, and the squeezing rotating rod 202 is rotated to squeeze the surface of the cloth. During the squeezing process, the rotating shaft 402 rotates, which will drive the active cavity 501 to be compressed, until the inverted U-shaped frame 201 rises, and the squeezing rotating rod 202 can automatically rotate in the opposite direction to reset through the elastic action of the compressed active cavity 501.

[0027] Among them, the limiting mechanism includes a limiting rod 601, both ends of which are fixedly connected to the inner wall of the inverted U-shaped frame 201, and one end of the extrusion rotating rod 202 is fixedly connected to a connecting block 602. The connecting block 602 is limited by the limiting rod 601, so that when the extrusion rotating rod 202 rotates during the resetting process, the extrusion rotating rod 202 stops rotating until the extrusion rotating rod 202 rotates and drives the connecting block 602 to abut against the limiting rod 601, so that the extrusion rotating rod 202 can stably maintain the inclined state, so that when the cloth pressing work is performed next time, the extrusion rotating rod 202 can stably abut the cloth and rotate.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
