Description

Technical Field

[0001] The utility model relates to the field of shoe processing equipment, in particular to an intelligent shoe upper sewing machine. Background Art

[0002] Shoes are items worn on the feet. Their main function is to protect the feet, provide comfort and support, and help people walk, run, stand or sit in different occasions. They are usually composed of soles and uppers.

[0003] As an important component of shoes, the upper usually includes a base material and a fabric fixed on the base material to increase the appearance or strength. The traditional sewing method is to draw lines on the base material first, place the fabric and base material in a stacked manner on the processing position of the sewing machine, align the fabric with the lines, and start the sewing machine to fix the fabric and base material along the edge of the fabric.

[0004] The above operation method has the following disadvantages: ① During operation, fingers need to press the fabric and the base material to ensure that their positions do not shift, but the pressing position is close to the processing position, which is easy to cause danger and cause harm to the workers; ② Operation efficiency and finished product quality are related to the proficiency of the workers. New workers will lead to reduced processing efficiency and increased unqualified rates. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the utility model is to provide an intelligent shoe upper sewing machine that automatically fixes the fabric and the base material, thereby improving processing efficiency and finished product quality and protecting workers.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: comprising a workbench and a sewing main machine fixed to the workbench, a sewing machine head is provided in front of the sewing main machine, and the workbench is located below the sewing machine head as a processing position, characterized in that: the workbench is provided with a movable base plate in the working position, a bottom plate is fixedly provided above the movable base plate, a substrate positioning hole consistent with the shape of the substrate is provided above the bottom plate, a pressing plate is provided above the bottom plate, a fabric positioning groove consistent with the shape of the fabric is provided below the pressing plate, sewing holes with edges consistent with the sewing trajectory are correspondingly provided on the pressing plate and the movable base plate, the pressing plate is provided with an adsorption mechanism for adsorbing the fabric to the fabric positioning groove, a lifting mechanism for driving the pressing plate to rise and fall is provided behind the movable base plate, and the workbench is provided with a transverse movement mechanism for driving the movable base plate to move left and right and a longitudinal movement mechanism for driving the transverse movement mechanism to move back and forth.

[0007] By adopting the above technical solution, during operation, the base material is first placed into the base material positioning hole of the bottom plate from above, and then the fabric is placed into the fabric positioning groove from under the pressing plate. At the same time, the fabric is adsorbed by the adsorption mechanism, and the pressing plate is driven down by the lifting mechanism until the fabric and the base material are pressed tightly, and the sewing machine head starts sewing. During the sewing process, the position of the movable base plate is adjusted by the transverse movement mechanism in conjunction with the longitudinal movement mechanism, so that the sewing machine head moves along the edge of the sewing hole until all sewing steps are completed. The pressing plate is driven up by the lifting mechanism, and the finished product is manually removed. The above structure has the following advantages: ① The sewing process is completed automatically to ensure processing efficiency, while avoiding danger to workers due to their hands approaching the processing position, thereby protecting the safety of workers; ② The relative position of the fabric and the substrate is defined by the fabric positioning groove and the substrate positioning hole, ensuring that the fabric and the substrate are accurately aligned while eliminating the inconvenience of drawing lines on the substrate and using lines for alignment; ③ An adsorption mechanism is added. On the one hand, after the fabric is placed in the fabric positioning groove from under the pressure plate, it maintains the accurate position and will not fall. On the other hand, after sewing is completed, as the pressure plate rises, the adsorption mechanism can bring the finished product of the fabric and substrate out of the substrate positioning hole, making material retrieval more convenient, thereby improving processing efficiency.

[0009] By adopting the above technical solution, the pipe joint is connected to the negative pressure air pump. The negative pressure airflow generated by the negative pressure air pump passes through each adsorption branch channel to form a negative pressure force on the adsorption fabric at the adsorption port. Multiple adsorption ports act simultaneously to stably adsorb the fabric in the fabric positioning groove.

[0010] The utility model is further configured as follows: the lifting mechanism includes a driving bracket fixed to the rear of the movable base plate, a cylinder is provided above the driving bracket, and a cylinder shaft for installing a pressure plate is driven and provided below the cylinder.

[0011] By adopting the above technical solution, the cylinder shaft is driven to rise and fall by the cylinder, providing reliable pressing force for the fabric and base material between the pressing plate and the bottom plate, avoiding misalignment between the two and ensuring stable sewing.

[0012] The utility model is further configured as follows: the transverse movement mechanism includes a track seat located behind the movable base plate and in contact with the workbench, the track seat is provided with a slide groove along the left and right directions, the track seat is slidably provided with a slide table for installing the movable base plate, a servo motor is fixedly provided at the end of the track seat, and the servo motor drives a screw rod provided along the slide groove and matched with the slide table thread.

[0013] By adopting the above technical solution, the servo motor drives the screw to rotate, and the front and rear positions of the movable base plate are accurately controlled, making sewing more accurate.

[0014] The utility model is further configured as follows: the longitudinal movement mechanism includes two servo electric cylinders located behind the sewing machine, and the two servo electric cylinders respectively drive forward an electric shaft that is fixedly matched with the track seat and moves synchronously, and the two electric shafts are respectively located on the left and right sides of the sewing machine.

[0015] By adopting the above technical solution, the space behind and on both sides of the sewing machine can be rationally utilized to install the servo electric cylinder, making the structure more streamlined. At the same time, the servo electric cylinder can accurately control the front and rear positions of the movable base plate, while the two electric axes that move synchronously can ensure the stable movement of the track seat.

[0016] The utility model is further configured as follows: the pressing plate is made of transparent material.

[0017] By adopting the above technical solution, the pressing plate is made of transparent material. On the one hand, it enables the staff to quickly and accurately load the fabric into the fabric positioning slot. On the other hand, it can visually observe the sewing process, discover problems in time and accurately locate the problem, which facilitates rapid debugging to improve processing efficiency.
