Description

Lifting sewing machine

Technical Field

The invention provides a lifting type sewing machine, and particularly relates to the technical field of sewing machine manufacturing.

Background

The sewing machine is sewing equipment for sewing clothes, bags, shoes, hats, bedding, clothes and the like, and the sewing process of the sewing machine is actually a feeding and sewing process by the cooperation of a feed dog, a presser foot and a machine needle. When the sewing machine starts to sew, the fabric is firstly placed under the presser foot to be sewn, and then the motor is started to sew. After sewing, the presser foot needs to be lifted to take out the sewing fabric. Because the presser foot of the sewing machine is lifted to a height of 15cm, the presser foot is not easy to be placed below the presser foot when meeting some super-thick fabrics, and the existing arrangement of lifting the presser foot can not meet the requirement of sewing thicker fabrics. In addition, the head and the bedplate of the existing sewing machine are fixed, and the distance between the thread feeding mechanism and the bottom thread mechanism is also fixed.

Disclosure of Invention

To make up the problem that there is the limitation in making up thick surface fabric in the presser foot technique of current sewing machine, this application provides a high over-and-under type sewing machine that can adjust, including frame and platen, its characterized in that, be provided with frame lift driving source between platen and the frame, can realize the technological effect of foretell frame lift through having set up frame lift driving source between platen and frame, reach the purpose that promotes the presser foot.

Preferably, the frame lifting driving source of the sewing machine is fixedly arranged on the table plate, the frame is fixed at the upper end of a lifting shaft of the frame lifting driving source, and the frame is connected with the machine head.

Preferably, a frame rotation driving source is fixedly mounted on the lifting shaft of the frame lifting driving source.

Preferably, the sewing machine further comprises a thread feeding mechanism, a bottom thread mechanism, an operation control panel and a controller, wherein the thread feeding mechanism is fixed on the long arm end of the machine head, the operation control panel is fixed on the machine frame, the bottom thread mechanism is fixed below the table plate, and the controller is fixed below the table plate.

Preferably, the bobbin thread mechanism is fixed between the bedplate and a fixed bracket provided on the bedplate.

Preferably, the thread feeding mechanism is structurally divided into an upper part and a lower part, the upper part is a handpiece rotating power source, the lower part is a handpiece, and the handpiece is fixed on an output shaft of the handpiece rotating power source.

Preferably, the bobbin thread mechanism is provided with a fixed seat and a bobbin thread rotating power source, the bobbin thread mechanism is installed on one side of the bedplate close to the machine head, the fixed seat is fixed on the fixed support, the bobbin thread rotating power source is installed and fixed below the fixed support, and an output shaft of the bobbin thread rotating power source is connected with the fixed seat.

Compared with the prior art, the beneficial effects of this application are: the utility model provides a technical effect that sewing machine of over-and-under type can realize foretell frame lift through set up the frame lift driving source between platen and frame reaches the purpose that promotes the presser foot, can carry out altitude mixture control according to the thickness of making up the surface fabric to the adaptation difference makes up the demand, this application has the advantage that the practicality is high, the commonality is strong.

Reference numerals: the upper thread mechanism 10, the machine head 11, the lower thread mechanism 20, the frame 30, the operation control panel 40, the bedplate 60, a frame lifting drive source 70, a lifting shaft 71, a frame rotating drive source 72 and a controller 80.

Detailed Description

The following detailed description of the preferred embodiments of the present application, taken in conjunction with the accompanying drawings, is provided to enable those skilled in the art to more readily understand the advantages and features of the present application, and is intended to more clearly and distinctly define the scope of the invention, which is set forth by way of illustration only and is not intended to be limiting of the invention.

FIG. 1 is a schematic view of an elevating sewing machine according to the present application. The sewing machine of the present application has an upper thread mechanism 10, a lower thread mechanism 20, a frame 30, an operation control panel 40, a controller 80, and a table 60. The thread feeding mechanism 10 is fixed on the long arm end of the machine head 11, the operation control panel 40 is fixed on the frame 30, the operation surface of the operation control panel 40 faces to an operator, the bottom thread mechanism 20 and the controller 80 are fixed under the bedplate 60, and the frame 30 is fixed on the bedplate 60.

A frame lifting driving source 70 is arranged between the table plate 60 and the frame 30 of the sewing machine, the frame lifting driving source 70 is used for adjusting the height of the frame 30, the frame lifting driving device can be started to lift the frame 30 when thick fabrics are sewn, and after the fabrics are placed, the frame 30 is lowered to the original height to perform sewing work. Specifically, the frame lifting driving source 70 is fixedly installed on the platen 60, the frame 30 is fixed on the upper end of a lifting shaft 71 of the frame lifting driving source 70, and the frame lifting driving source 70 is started to lift the lifting shaft 71, so that the frame 30 rotates together with the machine head 11.

The frame 30 of the sewing machine is also provided with a rotating function, the rotating device is used for rotating the frame 30 on the bedplate 60, the frame 30 and the needle threading mechanism 10 rotate to a certain angle together to meet the requirement of special sewing, and after the fabric is placed, the frame 30 is returned to the original position for sewing. The above-mentioned housing 30 is provided with a rotating function, specifically, a housing rotating drive source 72, and the housing rotating drive source 72 is mounted on the elevating shaft 71 of the housing elevating drive source 70.

The frame rotation driving source 72 may start the rotation operation and then start the frame lifting driving device 70 of the rotating frame 30, or the frame lifting driving device 70 may start the frame rotation driving source 72 to rotate after lifting the frame 30; alternatively, as another embodiment, the present sewing machine has only the frame elevation driving means 70; alternatively, the sewing machine has only the frame rotation driving source 72, and the lift shaft 71 is directly fixed to the table 60.

The upper thread mechanism 10 and the lower thread mechanism 20 constitute a sewing system of the sewing machine, and the controller 80 of the sewing machine controls the upper thread mechanism 10 and the lower thread mechanism 20 to cooperatively operate together to execute sewing.

The above description is only a preferred embodiment of the present application, and not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application, or which are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
