Description

Technical Field

[0001] This utility model relates to the field of low melting point flexible material processing technology, and in particular to a heated automatic rotating cutting knife transmission line. Background Technology

[0002] Flexible sheet materials with low melting points, such as rubber, soft plastic sheets, and linoleum, need to be cut to length on a conveying mechanism before use. An existing patent (publication number: CN222222746U) discloses a cutting device. This invention uses at least two cutting blades and a heating plate. On one hand, the heating plate heats the cutting blades to soften the material in contact with them, facilitating cutting. On the other hand, by driving a rotating shaft, the cutting blades can quickly cut the product during rotation, improving the cutting efficiency of the device. However, in practical applications, because the mechanical connection between the cutting blades and the heating plate lacks a stress-buffering structure, the cutting blades are prone to micro-cracks under long-term thermal cycling. This can lead to blade breakage during subsequent processing, shortening the blades' lifespan and potentially causing safety accidents, which is detrimental to practical applications. Therefore, we propose a heated automatic rotating cutting blade conveyor line. Utility Model Content

[0003] To solve the above problems, this utility model provides a heated automatic rotating cutting knife transmission line.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] Design a heated automatic rotary cutting knife conveyor line, including a cutter mounted above the conveyor line, a cutter housing connected to the conveyor line, the cutter connected to the cutter housing via a drive shaft, the drive shaft being connected to a rotary motor mounted inside the cutter housing, a pressure block fixed on the drive shaft, a cutter adjusting screw connected to the drive shaft on the pressure block, a cutter top wheel movably mounted inside the conveyor line and in contact with its top, a cutter mounting plate fixed on the drive shaft, a disc spring between the cutter and the cutter mounting plate, flanges fixed at both ends of the disc spring and respectively connected to the cutter and the cutter mounting plate, a heating rod attached to the cutter on the inner side of the cutter mounting plate, and a temperature sensor attached to the side of the cutter.

[0006] In the above scheme, a bearing mounting plate is fixed to the inner wall of the cutter box, and a rotary bearing connected to the drive shaft is fixed to the bearing mounting plate.

[0007] In the above scheme, the cutter box is equipped with a pressure roller that contacts the top of the conveyor line.

[0008] In the above scheme, pressure roller mounting plates are fixed at both ends of the pressure roller, and pressure roller shaft plates are provided on the side of the pressure roller mounting plates. The bottom end of the pressure roller shaft plate is connected to the pressure roller mounting plate through the pressure roller rotation shaft. A return spring is connected between the top end of the pressure roller shaft plate and the pressure roller mounting plate. The pressure roller shaft plate is fixed to the drive shaft, and pressure roller top screws are connected to the pressure roller shaft plate.

[0009] In the above scheme, the drive axis cutting box extends outward and a slip ring is movably sleeved at its end. A slip ring bracket is fixed on the bearing mounting plate, and the slip ring is fixed to the slip ring bracket.

[0010] In the above scheme, a sensor bracket is fixed to the outside of the slip ring bracket, a rotation angle sensor fixed to the sensor bracket is provided at the end of the drive shaft, and a drive pin is threadedly connected to the end of the drive shaft.

[0011] In the above scheme, a heat insulation plate is connected between the drive shaft and the cutter mounting plate.

[0012] The advantages and beneficial effects of this utility model are as follows: By setting up a cutter, a cutter mounting plate, a disc spring, and a flange, and using the cutter mounting plate as the mounting base for the cutter, the cutter is indirectly fixed to the drive shaft. Compared with the prior art, the disc spring located between the cutter and the cutter mounting plate absorbs most of the thermal expansion stress of the cutter. With the flange, both ends of the disc spring are connected to the cutter and the cutter mounting plate respectively. Utilizing the stiffness gradient characteristics of the disc spring, a graded buffering effect on impact loads can be achieved, effectively avoiding the concentration of thermal stress at the root of the cutter and preventing cracks. This not only extends the service life of the cutter but also improves safety, which is beneficial for practical applications. By setting up a cutter housing, the cutter, cutter mounting plate, heating rod, drive shaft, and temperature sensor are shielded. Compared with the prior art, this not only reduces the contact between the cutter and the outside environment, effectively reducing dust on the cutter surface, but also prevents workers from being injured by contact with the rotating cutter, further improving safety.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a heated automatic rotating cutting knife transmission line, including a cutter 10 disposed above the transmission line 1, and a cutter box 16 connected to the transmission line 1 outside the cutter 10. The transmission line 1 is used to transport materials and calculate the length of the materials.

[0020] Specifically, by setting up the cutter housing 16, the cutter 10, cutter mounting plate 9, heating rod 5, drive shaft 12 and temperature sensor 3 mentioned below are shielded. Compared with the existing technology, this not only reduces the contact between the cutter 10 and the outside world and effectively reduces dust on the surface of the cutter 10, but also prevents workers from being injured by contact with the rotating cutter 10, further improving safety.

[0021] The cutter 10 is connected to the cutter housing 16 via the drive shaft 12. The drive shaft 12 is connected to the rotary motor 14 installed in the cutter housing 16. A pressure block 15 is fixed to the drive shaft 12 by screws. The pressure block 15 is provided with a cutter adjustment screw 13 connected to the drive shaft 12. The cutter adjustment screw 13 is a commonly used technology that has been disclosed, so its structure will not be described in detail. The cutter adjustment screw 13 is used to prevent the drive shaft 12 from shifting and to improve the stability of the drive shaft. A cutter top wheel 2 is movably installed in the conveyor line 1 and contacts its top. A seated bearing is fixed in the conveyor line 1 by screws. That is, the cutter top wheel 2 contacts the inner side of the upper conveyor belt of the conveyor line 1, thereby providing support for the cutting action of the cutter 10. A cutter mounting plate 9 is fixed to the drive shaft 12 by screws. A disc spring 26 is provided between the cutter 10 and the cutter mounting plate 9. Flanges 27, which are connected to the cutter 10 and the cutter mounting plate 9 respectively, are fixed to both ends of the disc spring 26 by screws.

[0022] Specifically, by setting up a cutter 10, a cutter mounting plate 9, a disc spring 26, and a flange 27, the cutter mounting plate 9 serves as the mounting base for the cutter 10, indirectly fixing the cutter 10 to the drive shaft 12. Compared to existing technologies, the disc spring 26, located between the cutter 10 and the cutter mounting plate 9, absorbs most of the thermal expansion stress of the cutter. In conjunction with the flange 27, both ends of the disc spring 26 are connected to the cutter 10 and the cutter mounting plate 9, respectively. Utilizing the stiffness gradient characteristics of the disc spring 26, a graded buffering effect on impact loads can be achieved, effectively preventing thermal stress concentration at the root of the cutter 10 and preventing cracks. This not only extends the service life of the cutter 10 but also improves safety, which is beneficial for practical applications.

[0023] The inner side of the cutter mounting plate 9 is provided with a heating rod 5 that fits against the cutter 10. The cutter mounting plate 9 has a through groove for inserting the heating rod 5. The cutter mounting plate 9 is made of elastic material. The side of the cutter 10 is fitted with a temperature sensor 3.

[0024] Specifically, heating rod 5 is used to heat cutter 10, which helps cut materials with low melting points such as rubber, improving cutting efficiency. In conjunction with temperature sensor 3, the temperature of cutter 10 is monitored in real time for feedback, thereby achieving the effect of dynamically controlling the temperature of heating rod 5. It should be noted that the temperature of cutter 10 must not exceed the threshold. If the temperature exceeds the threshold, it may cause the blade of cutter 10 to anneal, and it may also cause the material to completely melt and adhere to the surface of cutter 10, which is not conducive to subsequent processing.

[0025] Furthermore, a bearing mounting plate 24 is fixed to the inner wall of the tool housing 16 by screws, and a rotary bearing 25 connected to the drive shaft 12 is fixed to the bearing mounting plate 24 by screws, thereby improving the stability of the drive shaft 12.

[0026] Furthermore, the cutter housing 16 is equipped with a pressure roller 18 that contacts the top of the conveyor line 1. After the cutter 10 cuts the material, the pressure roller 18 is used to press down the material behind it, thereby preventing the material from wrinkling or piling up.

[0027] Furthermore, pressure roller mounting plates 6 are fixed at both ends of pressure roller 18. Pressure roller mounting plates 6 are provided on the side of pressure roller shaft plates 11. The bottom end of pressure roller shaft plates 11 is connected to pressure roller mounting plates 6 through pressure roller rotation shaft 4. A return spring 8 is connected between the top end of pressure roller shaft plates 11 and pressure roller mounting plates 6. Pressure roller shaft plates 11 are fixed to drive shaft 12, and pressure roller set screws 7 are connected to pressure roller shaft plates 11. Among them, pressure roller set screws 7 are a commonly used technology that has been disclosed, so their structure will not be described in detail. Pressure roller set screws 7 are used to prevent displacement of pressure roller shaft plates 11 and improve stability.

[0028] Furthermore, the drive shaft 12 extends outward to the cutter housing 16 and is movably fitted with a slip ring 23 at its end. The slip ring 23 is a prior art that has been disclosed and is used to transmit electrical energy and signals, which solves the problem of breakage caused by wire twisting in rotating equipment. A slip ring bracket 22 that is rotatably mounted on the bearing mounting plate 24 and is fixed to the drive shaft 12 is fixed to the slip ring 23.

[0029] Specifically, a heat insulation sleeve is also provided coaxially between the slip ring 23 and the drive shaft 12 to block heat transfer, prevent the drive shaft 12 from being affected by the heat generated by the slip ring 23, and prevent the drive shaft 12 from aging rapidly.

[0030] Furthermore, a sensor bracket 21 is fixed to the outside of the slip ring bracket 22, and a rotation angle sensor 19 is fixed to the sensor bracket 21 at the end of the drive shaft 12. The rotation angle sensor 19 is fixed to the sensor bracket 21 by screws. A drive pin 20 is threaded to the end of the drive shaft 12. The drive pin 20 is a prior art that has been disclosed and is a common structure, so it will not be described in detail. The drive pin can reduce the radial runout of the drive shaft 12 on the one hand, and clamp the rotation angle sensor 19 on the other hand.

[0031] Furthermore, a heat insulation plate 17 is connected between the drive shaft 12 and the cutter mounting plate 9 to achieve heat insulation and prevent heat transfer.

[0032] Working principle:

[0033] The cutter 10 is heated to a specified temperature by the heating rod 5. The material is conveyed to the cutter via the conveyor line 1. The rotation speed of the cutter 10 is controlled by the rotary motor 14. The rotation speed of the cutter must be synchronized with the material conveying speed to cut the material evenly. During the material cutting process, because the cutter 10 is in a heated state, the material softens locally upon contact with the cutter 10, making it easier to cut. During the cutting process, the cutter top wheel 2 provides material support, preventing the belt from collapsing during the cutting process. The conveyor line 1 continues to transport the material. The material conveying length is calculated by the drive shaft of the conveyor line 1. After reaching the specified length, the cutter 10 continues to cut the material. The conveyor line 1 does not need to be stopped during the material cutting process, which saves working time.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
