Description

Technical Field

[0001] This utility model relates to the field of tape processing technology, and in particular to a knife holder mechanism for a Teflon tape slitting machine. Background Technology

[0002] Teflon tape is made by first coating glass fiber with Teflon emulsion and then drying it to form Teflon glass fiber cloth. It is then coated a second time with silicone adhesive to create a high-temperature resistant tape. During the production process, Teflon tape needs to be slit. A slitting machine is a device that longitudinally cuts wide rolls of material and is used in various industries. In the tape production process, the finished tape needs to be slit for easier use, and a tape slitting machine is required for this process. The blade holder is a component of the slitting machine that needs to be frequently disassembled and reassembled.

[0003] The existing tape slitting machine has a simple blade holder mechanism, which requires the operator to manually adjust the distance between several blades to the range required for tape slitting before turning on the slitting machine to allow the blades to slit the tape. This method of adjusting the distance between the blades is time-consuming and labor-intensive, increasing the workload of the operators.

[0004] Existing technology, patent number CN207890783U, discloses a blade holder mechanism for a tape slitting machine, which allows for manual adjustment of the spacing between blades without the need for manual operation, greatly reducing the workload of workers. However, in actual use, during the cutting process of Teflon tape, residual adhesive adheres to the blade edge, affecting slitting efficiency. This necessitates stopping the machine, disassembling the blade, and replacing it with a new one, which significantly impacts processing efficiency and reduces blade utilization. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a knife holder mechanism for a Teflon tape slitting machine.

[0006] This utility model is achieved through the following technical solution:

[0007] A blade holder mechanism for a Teflon tape slitting machine includes a frame, a crossbeam fixedly connected to the inner side of the frame, multiple sliding frames slidably connected to the outer side of the crossbeam, bolts rotatably connecting the top of each sliding frame, and a rotating blade changing mechanism located at the front of each sliding frame. The rotating blade changing mechanism includes a blade holder, one side of which is fixedly connected to one side of each sliding frame. A mounting rod is rotatably connected to the inner side of the blade holder, a blade is engaged with the outer side of the mounting rod, a coil spring is fixedly connected to the outer side of the mounting rod, one end of the coil spring is fixedly connected to the inner side of the blade holder, a locking block is fixedly connected to one end of the mounting rod, an electric push rod is fixedly connected to one side of the blade holder, and a stop rod is fixedly connected to the output end of the electric push rod. The outer side of the stop rod is connected to the blade holder. The inner sliding connection includes a limit block engaged on one side of the sliding frame, two screws inserted into the outer side of the limit block, a second tool holder fixedly connected to one side of the limit block, a push block inserted into the outer side of the second tool holder, a positioning rod fixedly connected to one side of the push block, the inner side of the positioning rod inserted into the outer side of the block, both ends of the blade having cutting edges, a spring fixedly connected to one side of the push block, a stop block fixedly connected to one end of the spring, the outer side of the stop block slidingly connected to the inner side of the push block, a pull rod fixedly connected to the inner side of the stop block, one end of the pull rod inserted into the outer side of the second tool holder, two fixed seats fixedly connected to one side of both the first and second tool holders, a limit ball rotatably connected to one side of each fixed seat; a cooling mechanism is provided on the outer side of the frame.

[0008] As can be seen, in the above technical solution, by utilizing the cutting edges at both ends of the blade, one end of the blade can be rotated and its direction changed in time after too much glue adheres to it, so that the cutting edge at the other end can continue to be used. It can be switched to the other side of the sharp cutting edge in time, avoiding problems such as cutting burrs and delamination caused by the dulling of the cutting edge.

[0009] Optionally, in one possible implementation, the cooling mechanism includes a water tank, the bottom of which is fixedly connected to the top of a frame, a water pump fixedly connected to the top of the water tank, an inlet pipe connected to the input end of the water pump, one end of the inlet pipe penetrating the inner wall of the water tank and extending into the interior of the water tank, a cooler installed inside the water tank, an outlet pipe connected to the output end of the water pump, a plurality of outlet pipes connected to one end of the outlet pipe, a hose connected to one end of the outlet pipe, a plurality of hoses connected to one side of the water tank, a pusher fixedly connected to one side of the baffle, the outer side of the pusher slidably connected to the inner side of the blade holder, a heat-conducting plate fixedly connected to the top of the pusher, a groove formed on the outer side of the heat-conducting plate, the groove having a "U" shaped cross-section, one end of the groove being connected through to one end of the hose, and the other end of the groove being connected through to one end of the hose.

[0010] As can be seen, in the above technical solution, a water pump is used to sequentially transport water inlet pipe, water outlet pipe one, water outlet pipe two, and hose one into the interior of the heat-conducting plate. Through the contact of the heat-conducting plate with the blade surface, the heat accumulated on the blade surface is generated, thereby improving the cutting efficiency of the blade.

[0011] The beneficial effects of this utility model are:

[0012] This utility model, by setting up a rotating blade changing mechanism, compared with the prior art, utilizes the transmission of the mounting rod by a coil spring, so that when one end of the blade becomes difficult to cut after a period of use, the blade edge can be quickly switched to the other side. This allows the Teflon tape to be replaced in a timely manner during the cutting process, improving production efficiency and continuity.

[0013] Meanwhile, by setting up a cooling mechanism, compared with existing technologies, the blade can be promptly heated through continuous water circulation after continuous cutting, which can prevent excessive heat accumulation on the blade, reduce blade sticking, and improve continuous operation capability.

[0027] Working principle of this utility model:

[0028] This utility model designs a knife holder mechanism for a Teflon tape slitting machine, the specific structure of which is shown in the attached instruction manual. Figure 1-7 As shown, in this technical solution, through the cooperation between various structures, multiple sliding frames 3 are first pushed to slide on the outside of the crossbeam 2, and then rotated by the corresponding bolts 4 to fix the position of the multiple sliding frames 3. Then, during the conveying of the Teflon tape, the Teflon tape will be cut into strips by multiple blade holders 1 5 and blade holder 2 12 through the corresponding blades 7. After that, during the cutting of the Teflon tape by multiple blades 7, the water pump 21 is started to draw water that has been injected into the water tank 20 in advance into the outlet pipe 1 23 and multiple outlet pipes 24 through the water inlet pipe 22. Then, the water is transported downward through multiple hoses 1 25 to the groove 29 inside the heat conduction plate 28. Then, the water flows through the "U" shape of the groove 29, allowing the water to flow through the heat conduction plate 28 to conduct heat to the groove 29 and the blades 7 in contact with the groove 29. The heat accumulated on the surface of the blades 7 will be transported back to the water tank 20 through the water inside the groove 29 and the hose 2 26 on the other side, thus completing the water circulation.

[0029] After using the blade 7 for a period of time, some residual adhesive will remain on the blade edge. Then, the electric push rod 10 is activated to retract, causing the stop rod 11 and pusher 27 to slide on the front side of the tool holder 5. This separates the stop rod 11 and the heat-conducting plate 28 from the bottom and one side of the blade 7. Then, the pull rod 17 is pulled, causing the stop block 16 to press against one side of the spring 15, separating the pull rod 17 from the outer side of the tool holder 12. Then, following the transmission force of the coil spring 8, the push block 14 can move with the drive of the mounting rod 6. At the same time, the mounting rod 6 will drive the blade 7. During the rotation of the blade 7, the electric push rod 10 will push the stop rod 11 to insert into one side of the blade holder 12. When the other end of the blade 7 rotates to the front end, the bottom side of the blade 7 will be blocked by the stop rod 11, so that the blade 7 can stop rotating. Then, the spring 15 pushes the stop block 16 to drive the pull rod 17 to insert into one side of the blade holder 12, so that the blade 7 can be fixed so that subsequent cutting can be carried out in time. Finally, the blade holder 12 can be pulled out from one side of the sliding frame 3 by the screws on one side of the two limit blocks 13, and the blade 7 after both ends have been used can be replaced.

[0030] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
