Description

Technical Field

[0001] This utility model belongs to the technical field of rewinding machines, specifically relating to a cutting tool for a glass spacer paper rewinding machine. Background Technology

[0002] A glass spacer rewinding machine is a key piece of equipment used to process glass spacer paper. During production, the spacer paper needs to be precisely cut to meet different specifications and sizes. The cutting blade system is its core component, and its main function is to ensure the neatness and consistency of the paper through an efficient cutting mechanism. To achieve this goal, the cutting blade design employs advanced technology.

[0003] The cutting tool includes a rotary lifting seat A and a rotary lifting seat B, which cooperate with a cutting roller between lifting bearing seats A and B. Multiple adjusting and fixing sleeves are fitted around the cutting roller, each equipped with an annular cutting blade. These annular blades provide a stable and uniform cutting effect during the cutting process. The lifting adjustment system of rotary lifting seats A and B is adjusted via lifting adjustment screws, allowing the cutting roller to be adjusted up and down according to the paper thickness and cutting requirements, thus ensuring precise contact between the cutting blade and the glass spacer paper. The position of the cutting roller and the pressure of the blade can be precisely adjusted via a handwheel to achieve the best cutting effect.

[0004] However, the cutting blades of the glass spacer rewinding machine mainly cut the glass spacer using ring-shaped cutting blades. When cutting the glass spacer using multiple ring-shaped cutting blades, the blades need to be fixed in position according to the required cutting distance. The glass spacer will automatically complete the cutting process as it passes through the multiple ring-shaped cutting blades. However, the ring-shaped cutting blades are mainly fixed in position by metal retaining sleeves. During cutting, the ring-shaped cutting blades are affected by reaction forces. Over time, the metal retaining sleeves that fix the ring-shaped cutting blades may loosen, causing the ring-shaped cutting blades to shift. This will result in the glass spacer not meeting the processing requirements after cutting. Utility Model Content

[0005] The purpose of this utility model is to provide a cutting blade for a glass spacer rewinding machine, so as to solve the problem mentioned in the background art that the annular cutting blade is mainly fixed in position by a metal fixing sleeve. However, during cutting, the annular cutting blade will be affected by the reaction force. After a long time, the metal fixing sleeve that fixes the annular cutting blade will easily loosen, which will cause the annular cutting blade to shift.

Both the spiral lifting seat A and the spiral lifting seat B have mounting base plates welded to their bottom ends. The spiral lifting seat A contains a lifting bearing seat A, and the spiral lifting seat B contains a lifting bearing seat B. A cutting roller is arranged between the lifting bearing seats A and B. Multiple adjusting and fixing sleeves are sleeved around the cutting roller. An annular cutting blade is arranged on the outer left end of each adjusting and fixing sleeve. A blade reinforcement device is connected between the top ends of the spiral lifting seat A and the spiral lifting seat B.

[0007] The blade reinforcement device includes a gantry frame, an adjustment slide groove, reinforcement blocks, and reinforcement support screws. The left and right ends of the gantry frame are fixedly connected to the return-type lifting seat A and the return-type lifting seat B respectively by screws. The gantry frame is provided with an adjustment slide groove, and multiple reinforcement support screws are inserted into the adjustment slide groove. The bottom end of each of the multiple reinforcement support screws is welded with a reinforcement block. The reinforcement support screws can slide left and right in the adjustment slide groove.

[0008] Preferably, the blade reinforcement device further includes a blade sleeve groove, a fixing nut A and a fixing nut B, and the blade sleeve groove is provided inside each of the plurality of reinforcement blocks. The blade sleeve groove can be sleeved on the outside of the top of the annular cutting blade, and the fixing nut A and the fixing nut B are sleeved on the external threads of the reinforcement support screw.

[0009] Preferably, the fixing nut A and fixing nut B are located on the upper and lower sides of the gantry frame, respectively. The fixing nut A can move upward and downward outside the reinforcing support screw by rotating clockwise and counterclockwise, and the fixing nut B can move downward and upward outside the reinforcing support screw by rotating clockwise and counterclockwise.

[0010] Preferably, both the lifting bearing seat A and the lifting bearing seat B have shaft holes at their centers, and the cutting roller has roller shafts at both ends. The two roller shafts are respectively inserted into the shaft holes inside the lifting bearing seat A and the lifting bearing seat B.

[0011] Preferably, lifting guide rails are provided on the inner walls of both the front and rear ends of the spiral-shaped lifting seat A and the spiral-shaped lifting seat B, and guide rail grooves are provided inside the front and rear ends of the lifting bearing seat A and the lifting bearing seat B, respectively, are sleeved on the outside of the lifting guide rails on the inner walls of the front and rear ends of the spiral-shaped lifting seat A and the spiral-shaped lifting seat B.

[0012] Preferably, both the U-shaped lifting seat A and the U-shaped lifting seat B have a lifting adjustment screw hole at the center of their top ends. A lifting adjustment screw is threaded into the lifting adjustment screw hole, and the lifting adjustment screw can move up and down in the lifting adjustment screw hole by rotating clockwise or counterclockwise through the action of the thread.

[0013] Preferably, both the lifting bearing seat A and the lifting bearing seat B are provided with screw fixing bearings at the center of their top ends.

[0015] Compared with the prior art, this utility model provides a cutting blade for a glass spacer rewinding machine, which has the following advantages:

[0016] This invention adds a novel blade reinforcement device between the tops of the two spiral lifting seats of the cutting blade in a glass spacer rewinding machine. After the multiple annular cutting blades on the cutting roller are locked in position by the adjusting and fixing sleeve, the blade reinforcement device can be adjusted so that the multiple reinforcing support screws on the device are locked above their corresponding annular cutting blades. After the multiple reinforcing support screws are firmly fixed, the reinforcing block at the bottom of the reinforcing support screw will be sleeved on the outside of the top of the annular cutting blade through the blade sleeve groove. This not only reinforces the position of the annular cutting blade through the reinforcing block and the blade sleeve groove, preventing the adjustment and fixing sleeve from causing the annular cutting blade to shift due to excessive length, but also allows the blade sleeve groove to remove dirt attached to the outer wall of the annular cutting blade and sharpen the blade through tight fit.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1-3The cutting blade of a glass spacer rewinding machine shown includes a spiral lifting seat A2 and a spiral lifting seat B8 symmetrically arranged on the right side of the spiral lifting seat A2. Both the spiral lifting seat A2 and the spiral lifting seat B8 have mounting base plates 1 welded to their bottom ends. A lifting bearing seat A3 is installed inside the spiral lifting seat A2, and a lifting bearing seat B9 is installed inside the spiral lifting seat B8. A cutting roller 4 is arranged between the lifting bearing seats A3 and B9. Multiple adjusting and fixing sleeves 5 are sleeved on the outside of the cutting roller 4. A ring-shaped cutting blade 6 is installed on the left side of each adjusting and fixing sleeve 5. A shaft hole 11 is provided inside the center of both the lifting bearing seats A3 and B9. Roller shafts 12 are provided at both ends of the cutting roller 4, and the two roller shafts 12 are respectively inserted into the shaft holes 11 inside the lifting bearing seats A3 and B9. Lifting guide rails are provided on the inner walls of both the front and rear ends of the spiral lifting seat A2 and the spiral lifting seat B8. 10. Guide rail grooves 13 are provided inside the front and rear ends of lifting bearing seats A3 and B9. The guide rail grooves 13 inside the front and rear ends of lifting bearing seats A3 and B9 are respectively sleeved on the outside of the lifting guide rails 10 on the inner walls of the front and rear ends of the circular lifting seats A2 and B8. Lifting adjustment screw holes 14 are provided inside the center of the top of the circular lifting seats A2 and B8. Lifting adjustment screws 15 are threaded into the lifting adjustment screw holes 14. The lifting adjustment screws 15 can move up and down in the lifting adjustment screw holes 14 by rotating clockwise and counterclockwise through the thread action. Screw fixing bearings are provided at the center of the top of the lifting bearing seats A3 and B9. The bottom ends of the two lifting adjustment screws 15 are rotatably connected to the two screw fixing bearings respectively. Adjusting handwheels are provided at the top of the two lifting adjustment screws 15. The adjusting handwheels can drive the lifting adjustment screws 15 to rotate.

[0023] like Figure 1 and Figure 2As shown, the center of both ends of the adjusting and fixing sleeve 5 is provided with embedded screw holes. Embedded screws are threaded into these holes. Tightening the embedded screws fixes the position of the adjusting and fixing sleeve 5 on the outside of the cutting roller 4. Loosening the embedded screws allows the adjusting and fixing sleeve 5 to slide left and right on the outside of the cutting roller 4. When installing the cutting blade of this glass spacer rewinding machine, firstly, the return-shaped lifting seat A2 and return-shaped lifting seat B8 need to be installed and fixed to their corresponding positions on the rewinding machine via the mounting base 1 at the bottom. Then, the glass spacer is moved out through the rewinding machine. The rewinding machine is stopped after the glass spacer passes the cutting roller 4. Then, the distance between the multiple cutting rollers 4 needs to be adjusted according to the cutting requirements of the glass spacer, ensuring that the distance between adjacent cutting rollers 4 meets the requirements. The glass spacer paper is cut according to the requirements. Then, the lifting adjustment screw 15 is rotated by operating the handwheel. The lifting adjustment screw 15 moves downward, thereby pushing the lifting bearing seat A3 inside the return-shaped lifting seat A2 and the lifting bearing seat B9 inside the return-shaped lifting seat B8 downward. The downward movement of the lifting bearing seat A3 and the lifting bearing seat B9 pushes the cutting roller 4 downward. The downward movement of the cutting roller 4 drives the multiple adjusting and fixing sleeves 5 to move downward until the annular cutting blades 6 on the multiple adjusting and fixing sleeves 5 are all tightly attached to the glass spacer paper and cut. Then, the rewinding machine is started again. The rewinding machine rewinds the glass spacer paper. When the glass spacer paper passes through the multiple annular cutting blades 6, it will be cut by the annular cutting blades 6, thereby completing the cutting process of the glass spacer paper.

[0024] like Figure 1 and Figure 3 As shown, a blade reinforcement device 7 is connected between the top ends of the rotary lifting seat A2 and the rotary lifting seat B8. The blade reinforcement device 7 includes a gantry frame 16, an adjusting slide 17, a reinforcing block 18, and reinforcing support screws 22. The left and right ends of the gantry frame 16 are fixedly connected to the rotary lifting seat A2 and the rotary lifting seat B8 respectively by screws. The gantry frame 16 is provided with an adjusting slide 17, and multiple reinforcing support screws 22 are inserted into the adjusting slide 17. The bottom end of each reinforcing support screw 22 is welded with a reinforcing block 18. The reinforcing support screws 22 can slide left and right in the adjusting slide 17. The blade reinforcement device 7 also includes The reinforcement blocks 18 include blade sleeve grooves 19, fixing nuts A20 and B21. Each of the reinforcement blocks 18 has a blade sleeve groove 19 inside. The blade sleeve groove 19 can be sleeved on the outside of the top of the annular cutting blade 6. The external threads of the reinforcement support screw 22 are fitted with fixing nuts A20 and B21. Fixing nuts A20 and B21 are located on the upper and lower sides of the gantry frame 16, respectively. Fixing nut A20 can move up and down outside the reinforcement support screw 22 by rotating clockwise and counterclockwise. Fixing nut B21 can move down and up outside the reinforcement support screw 22 by rotating clockwise and counterclockwise.

[0025] like Figure 1 and Figure 3 As shown, after the multiple annular cutting blades 6 on the cutting roller 4 are firmly fixed by the adjusting and fixing sleeves 5, in order to prevent the adjusting and fixing sleeves 5 from shifting due to prolonged use of the annular cutting blades 6, it is necessary to use the blade reinforcement device 7 to reinforce the position of the annular cutting blades 6 and prevent displacement. Taking the adjustment of a reinforcing support screw 22 on the gantry frame 16 as an example, firstly, it is necessary to rotate the fixing nut B21 clockwise and the fixing nut A20 counterclockwise, so that the fixing nut A20 and the fixing nut B21 move up and down respectively. This will unlock the reinforcing support screw 22 inserted in the adjusting slide groove 17. Then, it is necessary to slide the reinforcing support screw 22 left and right through the adjusting slide groove 17 to make the reinforcing support screw 22 slide. Move the reinforcing support screw 22 down above the corresponding annular cutting blade, so that the reinforcing block 18 at the bottom of the reinforcing support screw 22 is fitted onto the outside of the top of the annular cutting blade 6 through the blade sleeve groove 19. Then, maintain this state and rotate the fixing nut B21 counterclockwise and the fixing nut A20 clockwise, so that the fixing nut A20 moves downward and the fixing nut B21 moves upward, until the fixing nut A20 and the fixing nut B21 are firmly clamped at the upper and lower ends of the gantry frame 16, thus firmly fixing the reinforcing support screw 22. This allows the reinforcing block 18 to be firmly fitted onto the outside of the top of the annular cutting blade 6 through the blade sleeve groove 19, thereby reinforcing the position of the annular cutting blade 6 and protecting it.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
