Silicon paper unreeling frame utilizing limit switches

Abstract

The invention discloses a silicon paper unreeling frame utilizing limit switches. The silicon paper unreeling frame comprises a reeling roller, a first supporting frame, a second supporting frame and a motor, wherein the first supporting frame is connected with the second supporting frame through a connection rod, a fixing device is arranged above the first supporting frame which is sleeved with a conveying chain, a fixing device is arranged above the second supporting frame which is sleeved with a conveying chain, a lifting control part, the first limiting switch, the second limiting switch and the motor are arranged on one side of the second supporting frame, the lifting control part is connected with the first limiting switch, the second limiting switch and the motor through conductive wires, each conveying chain is provided with a lifting device, a second groove is formed in the middle of each lifting device which is provided with a transverse rod, the reeling roller is of a hollow structure, a plurality of movable blocks are embedded in the reeling roller, and an air inlet hole is formed in one end of the reeling roller. The silicon paper unreeling frame can prevent the phenomenon that reeled silicon paper and the unreeling roller slip, save labor, and protect the lifting devices.

Description

【Technical field】 [0001] The invention relates to the technical field of mechanical equipment, in particular to the technical field of unwinding racks. 【Background technique】 [0002] In the production process of various glued boards, the adhesive needs to be coated on the silicone oil paper first. The silicone oil paper is a commonly used packaging paper with a three-layer structure, the first layer is the bottom paper, the second layer is the coating, The third layer is silicone oil. In the production process of various types of glued boards, silicone oil paper unwinding racks are needed, but the silicone oil paper unwinding racks currently on the market have the following disadvantages: [0003] 1. Due to the smooth surface of the silicone oil paper, when it is wound on the traditional unwinding stand, the roll of silicone oil paper tends to move relative to the winding roller during unwinding, which affects the efficiency of unwinding and reduces the quality of the produ...

Problems solved by technology

[0003] 1. Due to the smooth surface of silicone oil paper, when it is wound on a traditional unwinding frame, the rolled silicone oil paper tends to move relative to the winding roller during unwinding, which affects the efficiency of unwinding and reduces the quality of the product , and if the silicone oil paper is wound too tightly, it will damage the silicone oil paper and make it unusable;

[0004] 2. After the silicone oil paper is wound on the early unwinding roller, it is necessary to manually place the unwinding roller on the unwinding frame. The traditional unwinding frame has no lifting device. It takes a lot of manpower to load and unload the unwinding frame, and the production efficiency is low.

[0005] 3. For the unwinding rack with lifting device, the limit switch is not used to effectively protect the lifting device, and the lifting device is easy to rise or fall too much, which will cause damage to the lifting device
