Description

Technical Field

[0001] The utility model relates to the technical field of epoxy reinforcing film processing, in particular to an adjustable tensioning and flattening mechanism for glass fiber covered cloth. Background Art

[0002] Reinforcement film is a multi-layer composite material, the main structure of which is the top layer of glass fiber or metal sheet skeleton material, the middle layer of epoxy resin / rubber as the base material, and the bottom layer of anti-sticking paper. This composite material can be made into various geometric sizes and shapes for customers according to their needs. When using, peel off the anti-sticking paper and stick it to the surface of the body steel plate that needs to be reinforced. After the electrophoresis baking process, the adhesive layer solidifies and hardens, and the skeleton material, adhesive layer and steel form a sandwich structure composite structure, thereby increasing the rigidity, bending strength and impact resistance of the steel plate. In the process of manufacturing epoxy reinforcing film, it is necessary to cover it with glass fiber cloth to enhance the reinforcement effect. Glass fiber cloth is divided into high alkali cloth, medium alkali cloth and alkali-free cloth according to the alkali content. The lower the alkali content, the better the flexural and tensile strength. These types of cloth can be distinguished according to their conductivity. High alkali cloth is a conductor and can be used as a wire, medium alkali cloth is a semiconductor, and alkali-free cloth is an insulator. The optical fiber used for signal transmission is glass fiber transmission, which is a high-alkali cloth. The medium-alkali cloth is suitable for magnesia cement building materials, and the alkali-free cloth is suitable for circuit boards, electronic grade.

[0003] The traditional way of covering the cloth is to use an ordinary fixed pressure roller. When covering reinforcement sheets of different thicknesses, the pressure roller cannot adjust the gap and roller pressure, which can easily cause wrinkles on the glass fiber cloth, thereby affecting the product appearance and reinforcement effect, causing economic losses; in addition, since the pressure roller is a fixed installation structure, when the production line is urgently stopped or the glass fiber cloth roll is replaced, the reinforcement material is easily rolled into the pressure roller, causing the production line to stop, causing great inconvenience to production, and also reducing production efficiency, and the practicality is relatively poor.

In this example, the limit assembly includes a fixed block 15, and the fixed block 15 is fixedly installed on one side of the pillar 1. The fixed block 15 is provided with a plug rod 16 on the side away from the empty tube 8, and a baffle 18 is rotatably sleeved on the outer wall of one end of the plug rod 16. A handle is connected to the end of the plug rod 16 close to the baffle 18. A spring 2 19 is sleeved on the outer side of the plug rod 16 between the baffle 18 and the fixed block 15. One end of the plug rod 16 passes through the fixed block 15 and is inserted into the jack provided on the side wall of the driving rod 9.

[0024] The working principle of the utility model is as follows: when in use, by twisting the screw rod 4 to make it move up and down, the slider 5 and the fixed rod 7 can be driven, and then the mounting seat 6 and the tensioning roller 3 can be driven to move upward or downward, so as to change the distance between the tensioning roller 3 and the auxiliary roller 2 and the roller pressure of the tensioning roller 3 on the reinforcing sheet blank, so as to achieve pressure balance, and can better press the fiberglass cloth on the reinforcing sheet blank, so as not to produce wrinkles; when the production line is urgently stopped or a new fiberglass cloth needs to be replaced, the handle is first pulled to drive the insertion rod 16 and the baffle 18, and the insertion rod 16 will drive the limit strip 17, and the movement of the baffle 18 will stretch the spring 2 19, so that the insertion rod 16 is inserted into the insertion hole and one end is moved out until the limit strip 17 is located close to the fixed block 15. The end of the near empty tube 8 is moved to the side of the fixing block 15 away from the empty tube 8, and the handle is twisted to drive the insertion rod 16 and the limit strip 17 to rotate. After the limit strip 17 is rotated to a position perpendicular to the initial position, the lower end of the limit strip 17 can be abutted against the side wall of the fixing block 15 to limit the insertion rod 16; and when it is necessary to fix the driving rod 9, the handle can be twisted to drive the insertion rod 16 and the limit strip 17 to rotate to the initial position and then release the applied force, so that the baffle 18 is reset under the elastic force of the spring 19, so that one end of the insertion rod 16 can be inserted into the corresponding insertion hole to complete the restriction and fixation of the driving rod 9, avoiding accidental touching of the push rod 10 to move the driving rod 9 and affecting the connection and fixing effect between the mounting seat 6 and the slider 5; then, the push handle can be pushed to drive the push rod 10 to move. The rod 10 pushes the driving rod 9 to move in the empty tube 8, and the driving rod 9 will squeeze the spring 14. At the same time, the movement of the driving rod 9 will cause the tooth groove provided on it to drive the gear 13 meshing with it to rotate, thereby driving the bidirectional screw 11 to rotate synchronously, so that the two ends of the bidirectional screw 11 will drive the connected fixing sleeve 12 to move in the adjusting groove 22, so that the two fixing sleeves 12 can move synchronously inwardly, that is, the fixing sleeve 12 inserted into the through groove can be moved out. At this time, the two ends of the empty tube 8 are synchronously lifted up, so that the empty tube 8 drives the mounting seat 6, and then the mounting seat 6 drives the tensioning roller 3 to move up synchronously, so that the mounting seat 6 will slide up along the fixing rod 7, and the stopper 20 connected to the lower end of the fixing rod 7 moves down in the adjusting cavity 23. The tensioning roller 3 is lifted, and when the tensioning roller 3 is restored to its original position, the lifting force applied to the empty tube 8 is released, so that the stop block 20 moves to fit the top wall of the adjusting chamber 23, and then the force applied to the push handle is released, so that the driving rod 9 is reset under the elastic force of the spring 14, and the driving gear 13 drives the bidirectional screw 11 to rotate, which can drive the fixing sleeve 12 to move, so that one end of the fixing sleeve 12 is inserted into the corresponding through groove thereon, and is connected and fixed with the fixing rod 7. Through the lifting mechanism, a new fiberglass cloth roll can be easily and quickly replaced, so that the reinforcing material not covered with fiberglass cloth is kept away from the tensioning roller 3, avoiding unnecessary adhesion and line stoppage. The fiberglass cloth roll can be quickly replaced without stopping the line to improve production efficiency, and it is easy to use and more practical.
