Description

Technical Field

[0001] This application relates to the field of planer technology, and more specifically to a planer with one output and multiple shapes. Background Technology

[0002] A planer is a device that uses planing tools to plan the flat, grooved, or shaped surfaces of a workpiece.

[0003] A planer with one output and one output includes an upper planer and a lower planer, both having a semi-circular cross-sectional groove. When a rectangular graphite plate passes between the upper and lower planers, the semi-circular cross-sectional groove on the upper planer scrapes away the upper half of the graphite plate, making the upper half of the plate semi-circular. Similarly, the lower planer scrapes away the lower half of the graphite plate, also making the lower half semi-circular. Thus, the rectangular graphite plate is transformed from a rectangular shape into a cylindrical shape, achieving the processing objective. However, in the above embodiment, only one cylindrical graphite rod can be processed at a time, resulting in low processing efficiency in mass production.

[0004] Therefore, there is a need for a planer with higher processing efficiency that can produce multiple shapes in one output. Summary of the Invention

[0022] A schematic diagram of a multi-faceted planer, for reference. Figures 1 to 6 According to a preferred embodiment of the present invention, a multi-bar milling planer is used to form graphite plates into multiple cylindrical graphite rods, including a machine base 10, a guide roller group 20, a planer blade assembly 30, and a rotating device group.

[0023] Specifically, such as Figure 1 As shown, the guide roller assembly 20 includes an upper pressure roller 201 and a lower pressure roller 202, both of which are rotatably mounted on the machine base 10; additionally, the planer assembly 30 includes an upper planer blade 301 and a lower planer blade 302, both of which are rotatably mounted on the machine base 10, as... Figure 4As shown, both the upper planer 301 and the lower planer 302 include a shaft portion 3011, a convex arc portion 3012, and a plurality of planing parts 3013. The sidewalls of the shaft portion 3011 are arranged in a ring array with the convex arc portions 3012. Each convex arc portion 3012 has a mounting groove 30121, and each mounting groove 30121 can be detachably installed with a planing part 3013. The planing part 3013 has a plurality of semi-circular cross-sectional grooves 30131 arranged side by side. In addition, the rotating device group includes a first rotating drive device 401 and a second rotating drive device. The first rotating drive device 401 is poweredly connected to both the upper planer 301 and the lower planer 302, and the second rotating drive device is poweredly connected to the lower planer 302.

[0024] It should be noted that in this application, one end of each of the lower pressure rollers 202 is connected to a second rotary drive device. During processing, the graphite plate is placed on the machine base 10 and pushed, feeding the graphite plate between an upper pressure roller 201 and a lower pressure roller 202. Since the rotation of the shaft of the second rotary drive device will drive the lower pressure roller 202 to rotate circumferentially, the graphite plate moves towards the lower planer 302 and is first planed by the lower planer 302. Because the planing part 3013 on the lower planer 302 has multiple semi-circular cross-sectional grooves 30131 arranged side-by-side, when the planing part 3013 contacts the lower surface of the graphite plate, referring to... Figure 6 The lower half of the graphite plate is planed and formed into a series of connected semi-circular arched protrusions. As the graphite plate is further fed to the upper planer 301, the planing part 3013 on the upper planer 301 contacts the upper surface of the graphite plate, and the upper half of the graphite plate is planed. At this time, the upper and lower semi-circular arched columns are spliced ​​into a whole cylinder. Since there is no excess material between the two adjacent whole cylinders, multiple cylindrical graphite rods are obtained. It should also be noted that the overall length of the graphite plate is greater than the distance between the nearest lower pressure rollers 202 on both sides of the planer assembly 30, so that the graphite plate can be continuously fed out in a predetermined direction. It is evident that compared with the prior art, which can only produce one graphite rod at a time, this application, by setting multiple parallel semi-circular cross-sectional grooves 30131 on the planing part 3013, can process multiple graphite plates simultaneously, which has the advantage of higher processing efficiency.

[0025] Furthermore, to remove the waste material from the planed portion of the graphite plate, such as... Figure 1 , Figure 2 and Figure 5As shown, the multi-form planer also includes two air hoods 501, air ducts 502, an exhaust device, and a collection box 503. Each of the upper planer 301 and the lower planer 302 has an air hood 501 on its opposite side. Each air hood 501 has a cavity, and the air hood 501 covers the upper planer 301 or the lower planer 302 through the cavity. The two ends of the air duct 502 are respectively connected to the cavity and the inlet 5031 of the collection box 503. The exhaust device is located inside the collection box 503.

[0026] It should be noted that when the graphite plate is planed and waste is generated, the exhaust device works and continuously applies a suction force to the hood 501, so the waste is sucked into the collection box 503 along the air duct 502, thereby collecting the waste and preventing the waste from being sucked in by the processing personnel and from interfering with the processing.

[0027] Specifically, to achieve the aforementioned waste collection, in this application, such as Figure 5 As shown, the collection box 503 has two inlets 5031, a collection chamber 5032, an air outlet 5033, a filter screen 5034, and an extension rod 5035. The two inlets 5031 are respectively connected to the two air ducts 502. The exhaust device includes a third rotary drive device 504 and a fan blade 505. The third rotary drive device 504 is installed on the top of the collection box 503, and the rotating shaft of the third rotary drive device 504 is connected to the extension rod 5035. One end of the extension rod 5035 away from the third rotary drive device 504 extends into the collection chamber 5032, and the fan blade 505 is provided on the end of the extension rod 5035 that extends into the collection chamber 5032. The filter screen 5034 is located between the inlets 5031 and the fan blade 505, and the filter screen 5034 is fixedly connected to the collection chamber 5032.

[0028] It should be noted that when the shaft of the third rotary drive device 504 rotates circumferentially, the extension rod 5035 rotates circumferentially and drives the fan blade 505 to rotate circumferentially, forming a negative pressure zone between the inlet 5031 and the outlet 5033. Since the inlet 5031 is connected to the air duct 502, the waste material, after being planed, is sucked into the air duct 502 under air pressure and enters the collection chamber 5032 along the inlet 5031. By setting the filter screen 5034, the risk of waste material flowing out from the outlet 5033 is avoided.

[0029] Furthermore, to reduce the risk of clogging of the filter 5034, such as Figure 5As shown, the extension rod 5035 passes through the filter screen 5034. The collection box 503 also includes a cleaning rod 5036, which is fixedly connected to one end of the extension rod 5035 that passes through the filter screen 5034. The cleaning rod 5036 has bristles that contact the filter screen 5034.

[0030] It should be noted that when the shaft of the third rotary drive device 504 rotates circumferentially, the bristles on the sweeping rod 5036 contact the filter screen 5034 and sweep away the waste material retained on the filter screen 5034.

[0031] In addition, to improve sealing and prevent waste from flowing out from the point where the extension rod 5035 passes through the filter screen 5034, such as Figure 5 As shown, two sealing rings 5037 are fitted on the extension rod 5035, and the two sealing rings 5037 are in contact with the filter screen 5034.

[0032] Furthermore, to achieve limiting the width of the graphite plate, such as... Figure 2 As shown, the multi-form planer also includes a side pressure roller 601 and a stop bar 602. The side pressure roller 601 is movably installed in the width direction of the machine base 10, and the stop bar 602 is fixedly installed on the machine base 10. The side pressure roller 601 and the stop bar 602 are arranged at intervals in the width direction of the machine base 10.

[0033] It should be noted that the side pressure roller 601 is adjustable in the width direction of the machine base 10 to accommodate graphite plates of different widths.

[0034] Furthermore, to specifically achieve the adjustment of the side pressure roller 601 in the width direction of the machine base 10, such as... Figure 2 and Figure 3 As shown, the machine base 10 includes a base 101 and an extension seat 102. The extension seat 102 is fixedly connected to the base 101 and has a sliding groove 1021. The multi-form planer also includes a swing rod 701, a connecting rod 702, a sliding member 703, a bolt 704, and a first nut 705. The middle section of the swing rod 701 is rotatably mounted on the extension seat 102. The sliding member 703 is slidably disposed on the sliding groove 1021. The two ends of the connecting rod 702 are rotatably connected to one end of the sliding member 703 and one end of the swing rod 701, respectively. One end of the bolt 704 passes through the sliding member 703, and the other end of the bolt 704 is threadedly connected to the first nut 705. The first nut 705 abuts against the extension seat 102. The other end of the connecting rod 702 is rotatably mounted with the side pressure roller 601. The rotatable connection between the connecting rod 702 and the swing rod 701 has a waist-shaped groove.

[0035] It should be noted that by rotating the first nut 705 and separating it from the extension seat 102, the sliding member 703 can be slid, and the swing rod 701 can swing at a predetermined angle, causing the side pressure roller 601 to move closer to or further away from the stop bar 602.

[0036] Furthermore, to enable the first rotary drive device 401 to simultaneously drive the upper planer blade 301 and the lower planer blade 302 to move, as follows: Figure 1 and Figure 2 As shown, the machine base 10 also includes an upper base 103, which is disposed on the top surface of the base 101. The upper pressure roller 201 is installed on one side of the upper base 103. The first rotary drive device 401 is fixedly installed on the upper base 103. One end of the upper planer 301 and the lower planer 302 are connected to an extension shaft 3011. The two extension shafts 3011 are respectively provided with a first pulley 3012 and a second pulley. The rotating shaft of the first rotary drive device 401 is provided with a third pulley 4011 and a fourth pulley 4012. The third pulley 4011 is belt driven connected to the first pulley 3012, and the fourth pulley 4012 is belt driven connected to the second pulley.

[0037] Furthermore, to achieve adjustability in the height direction of the upper pressure roller 201, such as... Figure 1 As shown, the upper seat 103 has a vertical plate 1031, a rotating plate 1032, a threaded rod 1033, a second nut 1034, and a spring on the side near the extension seat 102. The vertical plate 1031 is vertically arranged and fixedly connected to the upper seat 103. The middle section of the rotating plate 1032 is rotatably mounted on the vertical plate 1031. One end of the threaded rod 1033 passes through the upper seat 103, and the other end of the threaded rod 1033 is rotatably connected to the rotating plate 1032. The second nut 1034 is threadedly connected to one end of the threaded rod 1033 that passes through the upper seat 103, and the second nut 1034 abuts against the upper seat 103. Two upper pressure rollers 201 are rotatably mounted on both ends of the rotating plate 1032. The two ends of the spring abut against the upper seat 103 and the rotating plate 1032, respectively.

[0038] Furthermore, to further limit the height of the graphite plate during the planing process, such as... Figure 1 As shown, the guide roller group 20 also includes two auxiliary rollers 203. Both auxiliary rollers 203 are rotatably mounted on the upper seat 103, and the two auxiliary rollers 203 are located on both sides of the lower planer 302, and both auxiliary rollers 203 are located above the lower planer 302.
