Material tape feeding mechanism and quilting machine

Abstract

This utility model proposes a tape feeding mechanism and a quilting machine. The tape feeding mechanism includes a feeding component and a drive mechanism. The feeding component includes an inclined feeding platform with a channel running through it along the tape transmission direction. The two ends of the channel are an inlet and an outlet, respectively. The tape enters through the inlet and exits through the outlet. The drive mechanism includes a drive wheel, which is correspondingly positioned to the channel. This tape feeding mechanism has a simple structure. The drive wheel controls the tape feeding operation, and the tape feeding / receiving state and speed can be adjusted by regulating the speed and direction of rotation of the drive wheel. Replacing the existing tape feeding mechanism on a quilting machine with this new tape feeding mechanism, and installing it below the worktable of the quilting machine, better suits current sewing processes, resulting in more aesthetically pleasing stitches and a higher product qualification rate.

Technical Field

[0001] This utility model relates to the field of quilting equipment, and in particular to a material feeding mechanism and a quilting machine. Background Technology

[0002] The tape feeding mechanism is an important component of a quilting machine. On existing quilting machines, the tape feeding mechanism is mostly located above the quilting machine's worktable, releasing the tape from above. At this time, the direction of the tape in hand is opposite to the direction of force applied by the quilting needle, resulting in poor sewing effect and the inability to guarantee the aesthetics of the stitches.

[0025] Combination Figures 1 to 4The embodiment described herein proposes a material feeding mechanism, comprising a feeding assembly and a driving mechanism. The feeding assembly includes an inclined feeding platform with a channel 8 extending through it along the conveying direction of the material belt 10. The two ends of the channel 8 are an inlet 801 and an outlet 802, respectively. The height of the inlet 801 is less than the height of the outlet 802. The material belt 10 enters through the inlet 801 and exits through the outlet 802. The driving mechanism includes a driving wheel 4. A notch is provided at the bottom of the feeding platform corresponding to the driving wheel 4, communicating with the channel 8. The top of the driving wheel 4 passes through the notch and acts on the material belt 10 conveyed within the channel 8. The rotation of the driving wheel 4 drives the conveying of the material belt 10 within the channel 8.

[0026] The material feeding mechanism is mounted on the connecting arm 9. The drive mechanism also includes a power component 5, which is connected to the connecting arm 9. The output shaft of the power component 5 passes through the connecting arm 9 and is connected to the drive wheel 4, enabling the power component 5 to control the rotation of the drive wheel 4. The feeding assembly is connected to the connecting arm 9. The power component 5 described here can be a motor, such as a bidirectional motor capable of both forward and reverse rotation. The power, speed, etc., of the power component 5 can be directly controlled by a PLC control program. A tension detection device can be installed on the corresponding material belt 10 to monitor the tension of the material belt in real time.

[0027] A connecting shaft can be provided on the connecting arm 9 corresponding to the feed inlet 801. A material tray 1 is sleeved on the connecting shaft, and a material belt 10 is wound on the material tray 1.

[0028] The tilt angle α of channel 8 can range from 10° to 80°.

[0029] The edges of the feed inlet 801 and the discharge outlet 802 are chamfered to prevent the sharp edges of the feed inlet 801 and the discharge outlet 802 from scratching the material belt.

[0030] The aforementioned feeding platform may include a connecting plate and a cover plate 3. The connecting plate comprises two parts: one part is parallel to the cover plate 3 and connects with the cover plate 3 to form a channel 8; the other part is correspondingly connected to the connecting arm 9. The connection between the connecting plate and the cover plate 3, and between the connecting plate and the connecting arm 9, can be detachable. The portion of the connecting plate that connects to the connecting arm 9 can be divided into a first connecting plate 201 and a second connecting plate 202. In the conveying direction of the material belt, the first connecting plate 201 and the second connecting plate 202 can be respectively located at the two ends of the feeding platform to improve the stability of the feeding platform's connecting mechanism.

[0031] A guide plate 203 can be added to the lower part of the discharge port 801 of the feeding platform to guide the material belt output through the discharge port 801. This also prevents the material belt from being accidentally damaged by components below the material belt during subsequent transmission through the discharge port 801, ensuring the reliability of the material belt transmission. The guide plate 203 described here can be the same as the connecting plate.

[0032] Multiple holes 301 are provided on the cover plates 3 on both sides of the notch, and the holes 301 are connected to the channel 8. The holes 301 not only allow for good observation of the conveying of the material belt in the channel 8, but also facilitate the initial guidance of the material belt in the channel when the drive wheel 4 is not working.

[0033] The quilting machine includes the aforementioned material feeding mechanism, which is correspondingly positioned to the machine head and located below the worktable of the quilting machine. The material feeding mechanism is also corresponding to the lower sewing head 6, and a connecting arm 9 is connected to the lower sewing head 6. A fixing plate 7 is provided at the bottom of the lower sewing head 6. A lower clamping plate 601 can be added to the lower sewing head 6, with the upper end of the guide plate 203 corresponding to the upper surface of the lower clamping plate 601 to better guide the material feeding to the top of the lower clamping plate 601. A rotary hook power assembly can be connected to the lower sewing head 6. The rotary hook power assembly may include a servo motor 11, a belt drive assembly, and a rotary hook shaft 12. The servo motor 11 is connected to the lower sewing head 6, and its output shaft passes through the lower sewing head 6 and connects to the belt drive assembly, driving the rotary hook shaft 12 and the components connected to it to rotate. The rotary shuttle power assembly and the components connected to the rotary shuttle shaft 12 described herein can all be implemented using existing technologies, so they will not be elaborated upon here.

[0034] In some specific implementations, the height of the feed inlet 801 in the feed tape feeding mechanism is less than or equal to the height of the upper surface of the lower sewing machine head 6, and the height difference between the feed inlet 801 in the feed tape feeding mechanism and the upper surface of the lower sewing machine head 6 is less than 1 cm.

[0035] The matters not covered above can be directly implemented using existing technologies, so they will not be elaborated here.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several similar modifications and improvements can be made without departing from the inventive concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
