Description

Technical Field

[0001] The utility model relates to the technical field of sewing machines, and more specifically, to an intelligent sofa fabric sewing device. Background Art

[0002] Sofa fabric is a general term or abbreviation for textile fabrics used in making various sofas. In the process of making sofa fabrics, sewing machines are commonly used sewing equipment. Sewing machines use one or more sewing threads to form one or more stitches on the sewing materials, so that one or more layers of sewing materials are interwoven or sewn together. Sewing machines can sew cotton, linen, silk, wool, artificial fiber and other fabrics and leather, plastic, paper and other products. The stitches are neat, beautiful, flat and firm, with fast sewing speed and easy use. It has also derived art forms such as hand-push embroidery and computer embroidery.

[0003] The height of the sewing machine in the prior art is fixed and cannot be adjusted. It is difficult for users of different heights to achieve the best posture during use, which is inconvenient for users of different heights. The operation of the sewing machine often requires the operator to sit at the desk for a long time. Inappropriate sewing machine height will affect the operator's work efficiency and work quality.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an intelligent sofa fabric sewing device, which drives the movable legs and the processing table to rise and fall by setting sprockets and chains, so that it can be suitable for operators of different heights to perform comfortable operation.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: an intelligent sofa fabric sewing device, comprising a base and a processing table, a lifting mechanism is arranged between the base and the processing table, the lifting mechanism comprises a fixed support leg and a movable support leg, one end of the fixed support leg is fixedly connected to the base, the other end of the fixed support leg is provided with a slot for the movable support leg to be inserted and moved, a driving block is fixedly connected to the side wall of the movable support leg, and a through groove is arranged on the side wall of the slot for the driving block to extend and move, a mounting frame is arranged on one side of the base, a rotating rod is rotatably connected to the mounting frame, a driving member for driving the rotating rod to rotate is installed on the mounting frame, a sprocket is fixedly connected to the rotating rod, a chain is sleeved on the sprocket, one end of the chain is fixedly connected to the driving block, and the other end of the chain is fixedly connected to a counterweight block.

[0007] By adopting the above technical scheme, when the height of the sewing machine needs to be adjusted, the driving member is used to rotate the rotating rod, and the rotating rod can drive the sprocket to rotate after the rotation. The rotation of the sprocket can adjust the length of the chain on both sides of the sprocket. When the length of the chain on the side close to the driving block is shortened, the chain can drive the movable support leg to move up through the driving block. When the length of the chain on the side close to the driving block increases, the driving block and the movable support leg can be driven to descend. The height of the processing table can be adjusted according to needs, so that operators of different heights can also operate comfortably at the desk, thereby ensuring the sewing efficiency and quality of the sofa cover. Conversely, when the driving block moves up, the counterweight block will descend, and when the driving block descends, the counterweight block will move up. The counterweight block can be relative to the weight of the movable support leg and the processing table, so that the movement of the processing table is more stable.

[0008] The utility model is further configured as follows: a limiting rod is fixedly connected to the mounting frame, and a limiting groove for the limiting rod to pass through is arranged on the driving block.

[0009] By adopting the above technical solution, when the driving block moves up and down along with the chain, the driving block will always move along the limiting rod, so that the processing table is more stable during the movement.

[0010] The utility model is further configured as follows: a plurality of universal balls distributed in an array are arranged on the inner wall of the limiting groove.

[0011] By adopting the above technical solution, when the limit block moves along the limit rod, the universal ball will roll along the surface of the limit rod, reducing the friction between the limit rod and the driving block, making the movement of the driving block smoother.

[0012] The utility model is further configured as follows: a protrusion is fixedly connected to the side wall of the counterweight block, and a groove for the protrusion to be inserted and moved is arranged on the mounting frame.

[0013] By adopting the above technical solution, during the up and down movement of the counterweight block, the protrusion will always be inserted into the groove and move up and down along the groove, making its movement more stable.

[0014] The utility model is further configured as follows: a cross bar is rotatably connected to the mounting frame, one end of the cross bar is fixedly connected to a winding wheel, a pull rope with one end fixedly connected thereto is provided on the surface of the winding wheel, the other end of the pull rope is fixedly connected to the lower end surface of the counterweight block, and a synchronous linkage mechanism is provided between the winding wheel and the sprocket.

[0015] By adopting the above technical solution, when the sprocket is rotated by the rotating rod, the take-up wheel will rotate together with the sprocket through the synchronous linkage mechanism. In this way, when the counterweight block moves downward, the distance between the counterweight block and the take-up wheel will be reduced, and the pull rope will be wrapped around the take-up wheel due to the rotation of the take-up wheel. When the counterweight block moves upward, the take-up wheel will rotate in the opposite direction, and the pull rope will unfold from the take-up wheel. In this way, the take-up wheel and the pull rope can bear part of the pressure on the sprocket and the chain during the process of raising and lowering the processing table, so that the lifting and lowering of the processing table is more stable.

[0016] The utility model is further configured as follows: the synchronous linkage mechanism comprises a synchronous wheel 1 fixedly connected to the rotating rod, a synchronous wheel 2 is fixedly connected to the cross bar, and a synchronous belt is sleeved between the synchronous wheel 1 and the synchronous wheel 2.

[0017] By adopting the above technical solution, when the rotating rod rotates, the synchronous wheel 1 will rotate together. After the synchronous wheel 1 rotates, it can drive the synchronous belt to drive the synchronous wheel 2 to rotate together. The synchronous wheel 2 can drive the winding wheel and the sprocket to rotate together through the cross bar.

[0018] In summary, the utility model has the following beneficial effects:

[0019] The rotation of the sprocket in the utility model can adjust the length of the chain located on both sides of the sprocket. When the length of the chain located on the side close to the driving block is shortened, the chain can drive the movable support leg to move upward through the driving block. When the length of the chain located on the side close to the driving block is increased, the driving block and the movable support leg can be driven to descend. The height of the processing table can be adjusted according to needs, so that operators of different heights can also operate at the desk comfortably. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the chain 10 is fixedly connected to the driving block 6. The other end of the chain 10 is fixedly connected to a counterweight block 11. A protrusion 14 is fixedly connected to the side wall of the counterweight block 11. The mounting frame 7 is provided with a groove 15 for the protrusion 14 to be inserted and moved.

[0029] A cross bar 16 is rotatably connected to the mounting frame 7, one end of the cross bar 16 is fixedly connected to a winding wheel 17, a pull rope 18 is provided on the surface of the winding wheel 17, one end of which is fixedly connected to the winding wheel 17, the other end of the pull rope 18 is fixedly connected to the lower end surface of the counterweight 11, a synchronous linkage mechanism is provided between the winding wheel 17 and the sprocket 9, the synchronous linkage mechanism includes a synchronous wheel 19 fixedly connected to the rotating rod 8, a synchronous wheel 20 is fixedly connected to the cross bar 16, and a synchronous belt 21 is sleeved between the synchronous wheel 19 and the synchronous wheel 20.

[0030] When the height of the sewing machine needs to be adjusted, the driving member is used to rotate the rotating rod 8. After the rotating rod 8 rotates, the sprocket 9 can be driven to rotate.
