DETAILED DESCRIPTION
[0022] The following is combined with Figure 1-4 The utility model is further described.
[0023] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.
[0024] Reference Figures 1 to 4 The utility model provides an automatic trimming mechanism for forming a thermally conductive silicone sheet, which is arranged at the rear end of the thermally conductive silicone sheet calendering device, and is used for secondary trimming of the formed thermally conductive silicone sheet to remove excess edge material. The automatic trimming mechanism for forming a thermally conductive silicone sheet includes a base 1, a slide bar 11 and a blade clamp 2, wherein the base 1 is the base of the entire mechanism, and is used to install and support various components; the slide bar 11 is used to install the blade clamp 2 so that the blade clamp 2 can be adjusted in position, and the two ends of the slide bar 11 are rotatably connected to the base 1 on both sides thereof, and a slide bar 12 is sleeved on the slide bar 11; the blade clamp 2 is fixedly arranged on the slide bar 12, and a cutting knife 3 is clamped on the blade clamp 2, and the cutting knife 3 is used to trim the thermally conductive silicone sheet.
[0025] By arranging the automatic trimming mechanism for forming the thermally conductive silicone sheet at the rear end of the calendering device 4, the blade surface of the cutting knife 3 clamped on the blade fixture 2 faces the traction axis direction of the rear end of the calendering device 4. When the calendered product is moved to the corresponding position of the automatic trimming mechanism by traction, it will contact the blade surface of the cutting knife 3, so that while being moved by traction, the corresponding position of the product is cut by the cutting knife 3, so as to achieve the purpose of automatically cutting the product after calendering, reduce the process of manual secondary cutting, effectively improve production efficiency, and effectively ensure the flatness of the cut edge.
[0026] Reference Figure 1 and Figure 2 The slider 12 is sleeved on the slide rod 11, and the slider 12 can reciprocate on the slide rod 11 along the length direction of the slide rod 11. In actual use, the relative position of the slider 12 on the slide rod 11 can be adjusted according to the requirements of the product size, and then the position of the cutting knife 3 can be adjusted so that the size of the cut product meets the specification setting of the product.
[0027] In one embodiment, two sets of sliders 12 are provided on the slide bar 11, and a blade fixture 2 and a cutting knife 3 are correspondingly provided on each set of sliders 12. Two sets of cutting structures are provided, and when both sides of the product need to be cut and trimmed, the two sets of sliders 12 can be adjusted to the corresponding positions on both sides of the slide bar 11, so as to meet the needs of cutting at multiple knife positions at the same time, and effectively improve production efficiency.
[0028] Reference Figure 2 and Figure 3 The blade clamp 2 is provided with a cutting blade 3, specifically, the blade clamp 2 includes a blade base 21 and a tightening screw 22, the blade base 21 is fixedly connected to the slider 12, a blade mounting groove 211 is provided on the side of the blade base 21 facing away from the slider 12, the cutting blade 3 is installed in the blade mounting groove 211, the tightening screw 22 is threadedly connected to the mounting seat and the tail of the tightening screw 22 is inserted into the blade mounting groove 211, so as to press the cutting blade 3 against the groove wall of the blade mounting groove 211, thereby realizing the installation and fixation of the cutting blade 3.
[0029] In one embodiment, the blade clamp 2 also includes a pressure plate 23, which is used to press the cutting knife 3 against the blade mounting seat. The pressure plate 23 is movably arranged in the blade mounting slot 211, and the tightening screw 22 is threadedly installed in the blade mounting seat, and one end of the tightening screw 22 that penetrates into the blade mounting slot 211 is pressed against the side of the pressure plate 23 facing away from the cutting knife 3. A limiting boss 231 is provided on the side of the pressure plate 23 facing the cutting knife 3, and a blade limiting groove 232 is provided on the limiting boss 231, and the end of the cutting knife 3 away from the blade is stuck in the limiting groove 232. The number of tightening screws 22 can be one or more. In the present embodiment, two tightening screws 22 are provided to tighten different positions of the pressure plate 23 to ensure the reliability of the pressure plate 23 pressing against the cutting knife 3.
[0030] The pressure plate 23 can be set to better press and fix the cutting knife 3 in the blade mounting groove 211 to achieve the clamping of the cutting knife 3. In actual setting, the limiting boss 231 is staggered from the blade base 21, that is, when the pressure plate 23 presses the cutting knife 3 in the blade mounting groove 211, the limiting boss 231 does not abut against the groove wall of the blade mounting groove 211 to ensure that the pressure plate 23 can press the cutting knife 3 tightly against the groove wall of the blade mounting groove 211. The limiting groove 232 limits the cutting knife 3 to reduce the possibility of the cutting knife 3 falling off during use. The setting of the pressure plate 23 for clamping the cutting knife 3 is convenient, and it is convenient for the disassembly, assembly and replacement of the cutting knife 3 while satisfying the clamping effect of the cutting knife 3. The shape of the limiting groove 232 can be set according to actual needs to better adapt to the cutting knife 3.
[0031] Reference Figures 2 to 4 Furthermore, a limiting pin 212 protruding into the blade mounting groove 211 is fixedly connected to the blade base 21, and a limiting hole 31 is provided on the cutting knife 3. When the cutting knife 3 is installed on the blade base 21, the limiting pin 212 is inserted into the limiting hole 31 to limit the cutting knife 3. In actual setting, the length of the limiting pin 212 protruding into the blade mounting groove 211 is less than the thickness of the cutting knife 3, so as to ensure that the pressing plate 23 will not affect the pressing of the cutting knife 3 while limiting the cutting knife 3. The limiting pin 212 cooperates with the limiting hole 31 to further limit the cutting knife 3, further reducing the possibility of the cutting knife 3 falling off during use.
[0032] In some embodiments, both sides of the blade mounting seat can be threadedly connected with the tightening screws 22, so that the operator can change the position of the cutting blade 3 according to different cutting requirements to meet the processing requirements of different specifications and sizes.
[0033] In some embodiments, the length of the pressing plate 23 is generally set to be relatively long, so as to meet the requirements of clamping the cutting knives 3 of different lengths and ensure the stability of the cutting knives 3 when the cutting knives 3 are clamped. At the same time, by setting the length of the pressing plate 23 to be relatively long, the part of the cutting knives 3 that is away from the blade and exceeds the blade base 21 can be effectively shielded and protected, thereby reducing the possibility of the end of the cutting knives 3 causing danger to the operator, thereby improving the safety of the equipment and the operator.
[0034] In some embodiments, the slider 12 can rotate along the axis of the slide bar 11, and a fixing member for fixing the slider 12 to the slide bar 11 is provided on the slider 12. The fixing member is an angle adjustment screw 13, and a threaded hole 121 is provided on one side of the slider 12. The angle adjustment screw 13 is threadedly connected to the threaded hole 121, and the tail end of the angle adjustment screw 13 is pressed against the slide bar 11. When the position of the cutting knife 3 needs to be adjusted, the angle adjustment screw 13 is first loosened, and the slider 12 can be slid to slide the cutting knife 3 to the desired position. If the deflection angle of the cutting knife 3 needs to be adjusted, the slider 12 can be rotated to adjust the angle of the cutting knife 3. After the position and deflection angle of the cutting knife 3 are adjusted, the angle adjustment screw 13 is locked, so that the position of the slider 12 is locked and fixed, so as to reduce the deviation of the position and inclination angle of the cutting knife 3 during use. The adjustable deflection angle of the cutting knife 3 is conducive to the cutting work, so that the mechanism is applicable to more working conditions and can better cut the thermal conductive silicone sheet.
[0035] In other embodiments, the slide rod 11 adopts a screw rod, and the corresponding slider 12 adopts a screw slider 12. The screw slider 12 is driven to reciprocate by the rotation of the screw rod to achieve the cutting requirements of the mechanism for products of different specifications. An adjusting hand wheel (not shown in the figure) is set at the end of the screw rod, and the screw rod is driven to rotate by manually rotating the adjusting hand wheel to adjust the position of the cutting knife 3. The position adjustment is performed by the adjusting hand wheel, which has a simple structure and is easy to operate. It is also possible to connect a driving mechanism (not shown in the figure) to the end of the screw rod to drive the screw rod to work. The driving mechanism can be a driving part such as a servo motor. The servo motor drives the screw rod to rotate to adjust the position of the cutting knife 3, which effectively improves the accuracy of position adjustment.
