Description

Technical Field

[0001] The present invention relates to the field of cutting technology, in particular to a high-efficiency and stable cutting device for graphite coils. Background Art

[0002] Graphite coils have properties such as acid and corrosion resistance, high temperature resistance, electrical conductivity and thermal conductivity, and are therefore widely used in dynamic and static sealing of machines, pipes, pumps, and valves in the petroleum, alchemy, chemical, power generation, machinery and other industries.

[0003] Before use, graphite coils are often unwound and cut using a cutting device. Patent publication number CN218024581U discloses a single-shaft precision coil cutter. This machine first inserts a full roll of graphite coil onto a placement shaft, which is then rotated to rotate the coil. The cutting mechanism then directs the blade of the cutting mechanism toward the rotating coil, thereby segmenting the coil. However, during the cutting process, the blade pushes against the graphite coil, causing the cut end surface to tilt significantly. This creates an uneven surface, causing the coil to become loose and impacting subsequent cutting quality. Summary of the Invention

[0004] Based on this, it is necessary to provide an efficient and stable cutting device for graphite coils to address the technical problem that the current cutting device will make the cut end surface of the graphite coil uneven and thus affect the subsequent cutting quality.

[0005] The above purpose is achieved through the following technical solutions:

[0006] A high-efficiency and stable cutting device for graphite coils, comprising a support platform, a placement shaft rotatably provided on the support platform, the placement shaft being used to install the graphite coil, a cutting machine rotatably provided on the cutting machine, the cutter being a circular plate-shaped structure, the plane where the cutter is located being perpendicular to the axis of the placement shaft, the cutting machine being capable of sliding in directions parallel to and perpendicular to the axis of the placement shaft, respectively, thereby causing the cutter to cut multiple cutting slits on the graphite coil; a straightening plate is also provided on the cutting machine, the straightening plate being arranged parallel to the plane where the cutter is located, the distance between the straightening plate and the cutter being adjustable, the straightening plate being capable of moving radially along the placement shaft to be inserted into the cutting slit.

[0007] Furthermore, a fixing plate is fixed on the cutting machine, and a slide groove is provided on the fixing plate. The slide groove extends along the axial direction of the placement axis. A base is slidably provided in the slide groove, and the base is provided with an installation groove extending radially along the placement axis. The straightening plate is slidably provided in the installation groove at one end away from the placement axis.

[0008] Furthermore, a telescopic electric cylinder is provided inside the mounting groove, and a connecting block is provided at the end of the straightening plate away from the placement axis. The connecting block slides in the mounting groove and is connected to the output end of the telescopic electric cylinder. The telescopic electric cylinder can drive the straightening plate to slide radially along the placement axis.

[0009] Furthermore, a guide head is integrally formed at one end of the centralizing plate close to the placement shaft. Along the axial direction of the placement shaft, the thickness of the guide head is greater than the thickness of the centralizing plate, and there is an inclined transition between the guide head and the centralizing plate.

[0010] Furthermore, there are two slide grooves, and two sliders are provided on the base. The sliders correspond to the slide grooves one by one and slide together. One of the slide grooves is provided with a scale line, and the scale line is used to observe the position of the slider in the slide groove.

[0011] Furthermore, a screw is fixedly provided on one side of the slider away from the base, and a first nut is threadedly connected to the screw. By rotating the first nut so that the first nut fits with the fixing plate, the position of the slider in the slide groove can be limited.

[0012] Furthermore, the support platform also includes a support base plate. Along the axial direction of the placement shaft, a control box is provided on one side of the support base plate, and a side plate is provided on the other side. The placement shaft is rotatably arranged between the control box and the side plate.

[0013] Furthermore, the control box is provided with a chuck, which is used to clamp and fix one end of the placement shaft. The side plate is provided with a bearing seat, and the other end of the placement shaft is rotatably set in the bearing seat.

[0014] Furthermore, the support base is also provided with a first horizontal slide rail extending axially along the placement axis, a sliding seat is slidably provided on the first horizontal slide rail, and a first drive motor is provided on the sliding seat. The first drive motor can drive the sliding seat to slide along the first horizontal slide rail.

[0015] Furthermore, the sliding seat is provided with a second horizontal slide rail extending radially along the placement axis, the cutting machine is fixed with a chassis, and the chassis is provided with a second drive motor, and the second drive motor can drive the chassis to slide along the second horizontal slide rail.

[0016] The beneficial effects of the present invention are:

[0017] The present invention provides a highly efficient and stable graphite coil cutting device. First, a centralizing plate is provided. The centralizing plate can be inserted into the cutting slit to support one side of the graphite coil being cut, thereby reducing the tilt of the cut end surface of the graphite coil, making the cut end surface smoother and improving the cutting quality of the graphite coil. Furthermore, the distance between the centralizing plate and the cutter can be adjusted according to the length of each graphite coil being cut, providing a certain degree of versatility.

[0018] Second, the transition between the straightening plate and the guide head is beveled. The bevel enables each section of graphite coil to tilt a small distance toward the side of the straightening plate. This distance will not cause the graphite coil to scatter. At the same time, it increases the distance between the cutting end face of the graphite coil and the cutter, reducing the friction resistance between the two, so that the cutter can cut the graphite coil smoothly.

[0034] like Figures 1 to 10As shown, an embodiment of the present invention provides an efficient and stable cutting device for graphite coils, including a support platform, on which a placement shaft 103 is rotatably provided, and the placement shaft 103 is used to install a graphite coil 300. The support platform is also provided with a cutter 200, and the cutter 202 is rotatably provided on the cutter 200. The cutter 202 is a circular plate structure, and the plane where the cutter 202 is located is perpendicular to the axis of the placement shaft 103. The cutter 200 can slide in a direction parallel to the axis of the placement shaft 103 and a direction perpendicular to the axis of the placement shaft 103, respectively, so that the cutter 202 cuts multiple cutting slits 301 on the graphite coil 300; the cutting machine 200 is also provided with a straightening plate 214, and the straightening plate 214 is arranged parallel to the plane where the cutter 202 is located, and the distance between the straightening plate 214 and the cutter 202 is adjustable, and the straightening plate 214 can move along the radial direction of the placement shaft 103 to be inserted into the cutting slit 301.

[0035] During use, the cutting machine 200 is first controlled to cause the cutter 202 to cut a first cutting slit 301 in the graphite coil 300, thereby cutting the first section of the graphite coil 300. The cutting machine 200 is then controlled to cause the cutter 202 to cut a second cutting slit 301. Simultaneously, the centralizing plate 214 is controlled to be inserted into the first cutting slit 301, so that the centralizing plate 214 supports one side of the second section of the graphite coil 300 being cut. The support provided by the centralizing plate 214 reduces the tilt of the cut end surface of the graphite coil 300, making the cut end surface smoother and improving the cutting quality of the graphite coil 300. Furthermore, the distance between the centralizing plate 214 and the cutter 202 can be adjusted according to the desired cutting length of each section of the graphite coil 300, providing a certain degree of versatility.

[0036] like Figures 3 to 7 As shown, the cutting machine 200 is provided with a protective cover 203, which is used to prevent dust. The cutting machine 200 is fixed with a fixed plate 210, and the fixed plate 210 is provided with a slide groove 212. The slide groove 212 extends along the axial direction of the placement axis 103. A base 213 is slidably provided in the slide groove 212. The base 213 is provided with a mounting groove extending radially along the placement axis 103. The end of the straightening plate 214 away from the placement axis 103 is slidably provided in the mounting groove. Specifically, the cutting machine 200 is provided with a stud, and the fixed plate 210 is provided with a connecting hole. The stud passes through the connecting hole and is threadedly connected to a second nut 216. By rotating the second nut 216, the fixed plate 210 and the cutting machine 200 are detachably connected. By making the base 213 slide along the sliding groove 212 of the fixing plate 210 , the base 213 drives the straightening plate 214 to slide along the axial direction of the placement shaft 103 , thereby adjusting the distance between the straightening plate 214 and the cutter 202 .

[0037] Furthermore, a telescopic electric cylinder 215 is provided inside the mounting slot, and a connecting block 2141 is provided at the end of the centralizing plate 214 away from the placement axis 103. The connecting block 2141 slides in the mounting slot and is connected to the output end of the telescopic electric cylinder 215. The telescopic electric cylinder 215 can drive the centralizing plate 214 to slide radially along the placement axis 103. In this way, the telescopic electric cylinder 215 can control the centralizing plate 214 to enter or exit the cutting slit 301.

[0038] like Figures 8 to 10 As shown, the end of the centralizing plate 214 close to the placement shaft 103 is integrally formed with a guide head 2142. Along the axial direction of the placement shaft 103, the thickness of the guide head 2142 is greater than the thickness of the centralizing plate 214, and there is an inclined transition between the guide head 2142 and the centralizing plate 214. Figure 9 The cutter 202 cuts the graphite coil 300 from left to right, forming a section of the graphite coil 300 with each cut. The inclined surface allows each section of the graphite coil 300 to tilt slightly toward the centering plate 214, preventing the graphite coil 300 from becoming scattered. This distance also increases the distance between the cut end of the graphite coil 300 and the cutter 202, reducing friction between the two and enabling the cutter 202 to smoothly cut the graphite coil 300.

[0039] Furthermore, two slides 212 are provided, and two sliders 2133 are mounted on the base 213. The sliders 2133 correspond to and slide with the slides 212, facilitating smooth sliding of the base 213. A scale mark 211 is provided on one of the slides 212, which is used to monitor the position of the slider 2133 within the slide 212. This scale mark allows the distance between the straightening plate 214 and the cutter 202 to be read, facilitating adjustment of the cut length of each graphite coil 300.

[0040] Furthermore, a screw rod 2131 is fixedly provided on the side of the slider 2133 away from the base 213. A first nut 2132 is threadedly connected to the screw rod 2131. By rotating the first nut 2132 so that it fits against the fixing plate 210, the position of the slider 2133 in the slide groove 212 can be restricted. This facilitates adjustment of the distance between the straightening plate 214 and the cutter 202, making operation easy.

[0041] Furthermore, the support platform also includes a support base plate 102. Along the axial direction of the placement shaft 103, a control box 100 is provided on one side of the support base plate 102, and a side plate 104 is provided on the other side. The placement shaft 103 is rotatably set between the control box 100 and the side plate 104.

[0042] like Figure 2As shown, the control box 100 is provided with a chuck 1031, which is used to clamp and fix one end of the placement shaft 103. The side plate 104 is provided with a bearing seat 1041, and the other end of the placement shaft 103 is rotatably mounted in the bearing seat 1041. The control box 100 is provided with a third drive motor (not shown in the figure), which can control the rotation of the chuck 1031, thereby realizing the rotation of the placement shaft 103.

[0043] The support base 102 is further provided with a first horizontal slide rail 1021 extending axially along the placement axis 103. A sliding seat 108 is slidably mounted on the first horizontal slide rail 1021. The sliding seat 108 is provided with a first drive motor 109. The first drive motor 109 can drive the sliding seat 108 to slide along the first horizontal slide rail 1021. In this way, the cutting machine 200 can slide in a direction parallel to the axis of the placement axis 103.

[0044] The sliding seat 108 is provided with a second horizontal slide rail (not shown) extending radially along the placement axis 103. The cutting machine 200 is fixedly provided with a chassis 107. The chassis 107 is provided with a second drive motor 106. The second drive motor 106 can drive the chassis 107 to slide along the second horizontal slide rail. In this way, the cutting machine 200 can slide in a direction perpendicular to the axis of the placement axis 103.

[0045] like Figure 6 As shown, the cutting machine 200 is equipped with a cutting motor 201. The output end of the cutting motor 201 is equipped with a first gear 2011. The cutter 202 is drivingly connected to a second gear 2012. The first gear 2011 and the second gear 2012 are connected by a transmission belt. A support rod 105 is also provided between the control box 100 and the side panel 104. An operating box is slidably mounted on the support rod 105. The operating box is used to control the cutting motor 201, the first drive motor 109, and the second drive motor 106. The control box 100 is equipped with an operating panel 101, which is capable of controlling the third drive motor.

[0046] In combination with the above embodiments, the use principle and working process of the embodiments of the present invention are as follows:

[0047] During use, the graphite coil 300 to be cut is mounted on the placement shaft 103. The third drive motor is then controlled to rotate the placement shaft 103, and the distance between the straightening plate 214 and the cutter 202 is adjusted according to the desired cut length of each graphite coil 300. The cutting motor 201, the first drive motor 109, and the second drive motor 106 are then controlled to cause the cutter 202 to create a first cutting slit 301 in the graphite coil 300, forming the first segment of the graphite coil 300.

[0048] The cutting machine 200 is then controlled to move rightward, causing the cutter 202 to cut a second slit 301 in the graphite coil 300. Simultaneously, the telescopic cylinder 215 is controlled to simultaneously insert the centralizing plate 214 into the first slit 301. During initial insertion, the guide head 2142 of the centralizing plate 214 is closer to the graphite coil 300 than the end of the cutter 202. In other words, the guide head 2142 of the centralizing plate 214 protrudes beyond the end of the cutter 202, with a predetermined protrusion length a.

[0049] As the cutter 202 squeezes the second graphite coil 300 while cutting, causing it to expand outward to the left and right, the centralizing plate 214 supports the left side of the second graphite coil 300, minimizing its tilt. The slope between the guide head 2142 and the centralizing plate 214 tilts the second graphite coil 300 slightly toward the centralizing plate 214, preventing it from becoming disorganized. This also increases the distance between the cut end of the second graphite coil 300 and the cutter 202, reducing friction and enabling the cutter 202 to smoothly cut the graphite coil 300. As the straightening plate 214 and the cutter 202 move synchronously along the radial direction of the placement axis 103, the straightening plate 214 can always balance the extrusion force on the cutting area, so that the inner layer and the outer layer of the second section of the graphite coil 300 are not prone to excessive tilting, thereby making the cut end surface smoother and improving the cutting quality of the graphite coil 300.

[0050] Because the inner layers of the graphite coil 300 fit more tightly together during winding, while the outer layers fit more loosely together, the cutter 202 exerts a greater pressure on the inner layers of the graphite coil 300, resulting in a greater tilt in the cut area. The pressure exerted by the cutter 202 on the outer layers of the graphite coil 300 is less, resulting in a less tilt in the cut area. The telescopic electric cylinder 215 can be used to control the movement speed of the straightening plate 214, ensuring that after the straightening plate 214 and cutter 202 enter the interior of the graphite coil 300, the protrusion of the guide head 2142 is greater than a, with the protrusion increasing the closer the guide head 2142 is to the innermost layer of the graphite coil 300. This shortens the arm acting on the straightening plate 214, ensuring that the tilt of the inner and outer layers of the graphite coil 300 remains essentially the same.

[0051] After the second graphite coil 300 is cut, the straightening plate 214 and the cutter 202 stop moving. The cutter 202 and straightening plate 214 are then reset, and a stopper (not shown) is manually inserted into the first cutting slit 301. This stopper prevents the first and second graphite coils 300 from interfering with each other.

[0052] Finally, the above steps are repeated multiple times to obtain multiple sections of graphite coils 300 .

[0053] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
