Description

Technical Field

[0001] The invention relates to the field of surface treatment of grinding wheel reinforced mesh cloth, and in particular to a grinding wheel mesh cloth integrated unwinding device with lifting and lowering cloth connection, heat sealing, and active unwinding functions. Background Art

[0002] In recent years, with the continuous increase in external grinding wheel mesh manufacturers and the increasingly similar product quality levels, the market has faced increasingly fierce competition. On the other hand, the quality of the company's grinding wheel mesh products has fluctuated, requiring a systematic solution. The unwinding of the grey fabric is also a key link. Currently, during the surface treatment process of the grinding wheel mesh grey fabric, the grey fabric is unwound passively. The grey fabric roll is wrapped around a steel pipe and relies entirely on the power of the winding traction to transport the grey fabric. This causes the tension of the fabric surface to be in a state of disordered control, which can easily cause the grey fabric to shift or stretch. Secondly, to ensure continuous production without stopping the machine, the fabric is still connected by sewing machines. The joints are thick, which affects the quality control of the grinding wheel mesh after gluing and affects normal continuous production. Even due to human negligence, it is easy for materials to not be connected in time during the production process, causing downtime or even production suspension. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide a grinding wheel mesh cloth integrated unwinding device with the functions of lifting and lowering cloth connection, heat sealing and active unwinding.

[0004] In order to solve the above technical problems, the technical solution of the present invention is: an integrated unwinding device for grinding wheel mesh with lifting and lowering cloth connection, heat sealing and active unwinding functions, the innovation of which is:

[0006] an air expansion shaft, on which a grinding wheel mesh blank cloth roll is sleeved, and which is horizontally arranged below one width side of the heat-sealing cloth platform;

[0007] a cloth guide roller group, which is arranged on both sides of the width of the heat-sealing cloth platform and above the grinding wheel mesh cloth roll;

[0008] A heat sealing device is arranged vertically above the heat sealing platform.

[0009] a lifting cloth joining device, the lifting cloth joining device comprising a lifting cloth joining platform and an electric cylinder connected in an upper and lower manner, the lifting cloth joining platform being arranged on a width side of the heat-sealing cloth joining platform close to the grinding wheel mesh grey cloth roll, and the lifting cloth joining platform being driven by the electric cylinder to rise vertically to a position higher than the heat-sealing cloth joining platform, or to fall vertically to a position lower than the heat-sealing cloth joining platform;

[0010] A servo reduction motor is also installed on the side of the main frame close to the air expansion shaft. The air expansion shaft is driven to rotate by the servo reduction motor. A photoelectric sensor is also installed on the main frame between the third unwinding guide roller and the air expansion shaft through a sensing substrate.

[0011] Furthermore, the cloth guide roller group includes a first unwinding cloth guide roller, a second unwinding cloth guide roller and a third unwinding cloth guide roller. The first unwinding cloth guide roller and the third unwinding cloth guide roller are respectively arranged on both sides of the width of the heat-sealing cloth platform, and the third unwinding cloth guide roller is above the air inflation shaft. The second unwinding cloth guide roller is arranged above the first unwinding cloth guide roller.

[0012] Furthermore, it also includes a cloth brake device, which includes a cloth brake tube and a first cylinder connected up and down, and the cloth brake tube is arranged vertically on the first unwinding guide roller.

[0013] Furthermore, it also includes a main frame, the air-inflating shaft is installed on the main frame through an unwinding bearing seat, and the third unwinding cloth guide roller is installed at the middle position of the main frame through an electric cylinder mounting plate.

[0018] The advantages of the present invention are:

[0019] 1. In the present invention, after the unwinding of the previous roll of grey cloth is completed, the tail of the cloth rises to the point where it is out of the detection range of the photoelectric sensor. The cloth brake tube in the cloth brake device immediately rises to press the previous roll of grey cloth against the first unwinding guide roller, and the tail of the previous roll of grey cloth is locked on the heat-sealing platform. At the same time, the servo reduction motor stops running, and the lifting and splicing platform rises. At this time, the production line operates normally, consuming the grey cloth in the cloth storage rack. The worker spreads the heat-sealing adhesive strip of the grinding wheel mesh grey cloth flatly on the fabric surface of the previous roll of grey cloth on the heat-sealing platform, and then arranges and spreads the starting section of the next roll of grey cloth flatly on the lifting and splicing platform, waiting for the worker to After the cloth ends are arranged, they are allowed to hang freely and overlap the heat-sealing strips on the heat-sealing platform. Finally, the heat-sealing device is used to bond the ends of the front and rear grey fabrics together, abandoning the traditional method of stitching with a sewing machine. This will not affect the quality control of the grinding wheel mesh after gluing. After the heat-sealing is completed, the heat-sealing device automatically rises, the brake cloth pipe and the lifting cloth-sealing platform retract synchronously, and the servo reduction motor runs synchronously and is linked to the cloth storage rack for tension. During the operation of the whole machine, the tension of the cloth surface can be continuously controlled to avoid displacement or stretching of the grey fabric, thereby achieving smooth material transportation and continuous production without stopping the machine. It also avoids the problem of human negligence causing materials to be not connected in time during the production process, resulting in downtime or even production suspension.

[0020] 2. In this invention, the grinding wheel mesh fabric roll is mounted using an air shaft, and a servo reduction motor is used to actively unwind the grinding wheel mesh fabric roll. The first, second, and third unwinding guide rollers work together to transport the grinding wheel mesh fabric. 3. The guide roller assembly also includes a tension sensor. Feedback from the tension sensor is used to dynamically match the control of the servo reduction motor using a PLC, thereby achieving constant tension control between this structure and the fabric storage rack.
