Description

Technical Field

[0001] The present invention relates to the technical field of carbon crystal heating plates, and particularly relates to a preparation method of a flame-retardant carbon crystal heating plate. Background Art

[0002] A carbon crystal heating plate is made by adding a far-infrared emitter and a temperature-limiting agent to microcrystalline particles and through a special process. It is mainly applicable to heating in families, office buildings, school dormitories, hospitals, hotels, guesthouses, and bath centers, as well as heat preservation in greenhouse sheds and warehouses.

[0003] The invention patent with the authorization announcement number CN 106466933 B discloses a flame-retardant carbon crystal heating plate and a preparation method thereof. The preparation method includes: 1) First, fix one end of a copper bar on the front surface of a first resin layer and extend the other end outside the first resin layer; 2) Then, apply graphite carbon paste on the front surface of the first resin layer to form a graphite layer, and one end of the copper bar is covered by the applied graphite carbon paste; 3) Hot-press a second resin layer onto the graphite layer to obtain a sandwich panel; 4) Hot-press mica paper on both sides of the sandwich panel, and after natural cooling, obtain a flame-retardant carbon crystal heating plate. This flame-retardant carbon crystal heating plate can heat evenly for a long time, has good high-voltage resistance and heat resistance, and is safe to use.

[0004] After research by those skilled in the art on the above method, it is found that since the preparation of two mica layers is required, that is, two hot-pressing operations are needed, in order to avoid affecting the preparation efficiency of the carbon crystal heating plate due to sequential hot-pressing, those skilled in the art thought of simultaneously hot-pressing the mica layers on both sides of the sandwich panel to improve the preparation efficiency of the carbon crystal heating plate.

[0005] However, it is found that in actual operation, since the hot-pressing of the mica layers on both sides needs to be carried out simultaneously, when placing the mica paper and the sandwich panel, it is necessary to arrange them in the order of mica paper, sandwich panel, and mica paper from bottom to top. And because the mica paper is relatively thin and prone to wrinkles, when the placement of the two mica papers is completed, it is necessary to level the surface of the mica paper to avoid the generation of wrinkles, which not only wastes manpower but also causes a certain reduction in the preparation efficiency of the carbon crystal heating plate.

[0006] In addition, during the process of placing the sandwich panel and adjusting its position, the lower mica paper is prone to scratches or slight damage on the surface due to the sliding of the sandwich panel, thereby reducing the quality of the subsequent mica layer.

[0007] Therefore, it is very necessary to invent a preparation method of a flame-retardant carbon crystal heating plate to solve the above problems. Summary of the Invention

[0013] The lifting plate is fixedly arranged on the top of the inner sleeve, the positioning groove is opened on the top of the lifting plate, the second outer plate is fixedly sleeved on the bottom outside the lifting plate, the rack is fixedly arranged on the top of the second outer plate, and the limiting block is located directly above the second outer plate and is fixedly connected to the inner wall of the housing.

[0014] Preferably, the clamping and positioning mechanism includes a stop block, a guide rod, a positioning clamping plate, an inclined surface push block, a baffle plate and a second spring.

[0015] Preferably, the stop block is located inside the lifting plate, the guide rod slidably penetrates through the stop block and is fixedly connected to the inner wall of the lifting plate, the positioning clamping plate is slidably nested inside the positioning groove and extends into the lifting plate, the inclined surface push block and the baffle plate are fixedly arranged on the inner side of the positioning clamping plate in sequence from top to bottom, and the second spring is fixedly connected between the outer side of the positioning clamping plate and the inner wall of the lifting plate.

[0016] Preferably, the paper laying mechanism includes a back plate, a winding roller, a guide roller, a mica paper tape and a gear.

[0017] Preferably, the back plate is fixedly arranged on the top of the outer shell, the winding roller and the guide roller are rotatably nested on the front side of the back plate through bearings, the mica paper tape is wound on the outside of the winding roller, and the gear is located at the rear end of the winding roller and is connected to the winding roller through an overrunning clutch.

[0018] Preferably, the hot pressing and cutting mechanism comprises a side plate, a sliding plate, a trigger groove, a hot pressing plate, a third spring, a cutting knife, an end plate and a fourth spring.

[0019] Preferably, the side plate is fixedly connected to the inner wall of the shell, the sliding plate is slidably penetrated and arranged at the bottom of the side plate, the trigger groove is opened at the bottom of the sliding plate, the hot pressure plate is fixedly arranged at the end of the sliding plate, the third spring is sleeved on the outside of the sliding plate and fixedly connected between the side plate and the hot pressure plate, the cutter is slidably penetrated and arranged at the top of the side plate, the end plate is fixedly arranged at the top of the cutter, and the fourth spring is fixedly connected between the side plate and the end plate.

[0020] Preferably, the method specifically comprises the following steps:

[0021] S1. Insert the core plate into the inner side of the positioning groove, keep the core plate in a vertical state inside the positioning groove, start the driving motor, and after the driving motor is started, the reciprocating screw is driven to rotate continuously. When the reciprocating screw rotates, the outer sleeve is driven to rise continuously. When the outer sleeve rises, the lifting plate is driven to rise through the first spring and the inner sleeve, and the trigger rod is driven to rise through the first outer sleeve;

[0022] S2, when the lifting plate rises, it drives the core plate to rise, and at the same time drives the rack to rise through the second outer sleeve plate. When the rack rises, it drives the gear to rotate, and then the gear drives the winding roller to rotate synchronously. When the winding roller rotates, the mica paper tape is continuously output, so that the mica paper tape gradually reaches the hot pressing station;

[0023] S3, during the lifting process of the lifting plate, the reciprocating screw rod relatively descends inside the lifting plate, thereby gradually releasing the lifting of the block. As the block continues to descend, the block gradually releases the blocking of the baffle, and the compressed second spring pushes the positioning clamping plate to move in the direction close to the core plate. During the movement of the positioning clamping plate, the inclined push block moves synchronously, thereby gradually lifting the core plate;

[0024] S4, when the rising distance of the outer sleeve reaches the first threshold, the positioning clamping plate fits with the core plate, and the core plate moves out from the inner side of the positioning groove under the push of the inclined push block. When the rising distance of the outer sleeve reaches the second threshold, the top of the second outer sleeve fits with the bottom of the limit block. At this time, the core plate and the mica paper both arrive at the hot pressing station, and the top of the core plate fits with the bottom of the limit plate. At the same time, due to the limitation of the limit block, the second outer sleeve, the lifting plate and the inner sleeve cannot continue to rise. Subsequently, as the reciprocating screw continues to rotate, the outer sleeve drives the trigger rod to continue to rise through the first outer sleeve;

[0025] S5. When the rising distance of the outer sleeve reaches the third threshold, the trigger rod fits against the inner wall of the trigger groove. Subsequently, as the outer sleeve continues to move upward, the trigger rod pushes the sliding plate through the trigger groove, thereby causing the sliding plate to drive the hot pressing plate to move while stretching the third spring.

[0026] S6. When the rising distance of the outer sleeve reaches the fourth threshold, the hot pressing plate presses the mica paper against the side of the core board, and then the hot pressing operation begins. When the rising distance of the outer sleeve reaches the fifth threshold, the trigger rod fits against the cutter. Subsequently, as the outer sleeve continues to rise, the trigger rod pushes the cutter to move, and at the same time, the cutter compresses the fourth spring through the end plate.

[0027] S7. When the rising distance of the outer sleeve reaches the sixth threshold, the cutter cuts off the mica paper tape at the joint of the core board and the limiting plate. When the rising distance of the outer sleeve reaches the seventh threshold, the outer sleeve moves to the top of the reciprocating thread on the outside of the reciprocating screw. Subsequently, as the reciprocating screw continues to rotate, the outer sleeve moves downward to reset.

[0028] S8. As the outer sleeve continues to move downward, the hot pressing and cutting mechanism, the clamping and positioning mechanism, and the second driving mechanism are reset one after another. During the downward reset process of the rack in the second driving mechanism, due to the existence of the overrunning clutch between the gear and the winding roller, the gear rotates while the winding roller does not rotate.

[0029] S9. When the downward movement distance of the outer sleeve reaches the eighth threshold, the outer sleeve moves to the bottom of the reciprocating thread on the outside of the reciprocating screw and reaches the initial station at the same time. At this time, manually remove the formed carbon crystal heating plate after hot pressing and stop the driving motor.

[0030] Technical effects and advantages of the present invention:

[0031] By providing a first driving mechanism, a second driving mechanism, a clamping and positioning mechanism, a paper laying mechanism, and a hot pressing and cutting mechanism, the present invention facilitates driving the second driving mechanism by the first driving mechanism, thereby causing the second driving mechanism to lift the clamping and positioning mechanism and the core board while triggering the paper laying mechanism. After the clamping and positioning mechanism is lifted, it automatically completes the clamping and positioning of the core board. After the paper laying mechanism is triggered, it automatically realizes the output of the mica paper. Subsequently, the first driving mechanism triggers the hot pressing and cutting mechanism twice successively, thereby completing the hot pressing operation on both sides of the core board and cutting off the mica paper. Compared with the same type of devices and methods in the prior art, the present invention can not only perform the hot pressing process on the mica layers on both sides of the core board simultaneously, but also keep the mica paper flat by using gravity, thereby avoiding wrinkles and realizing the fitting of the mica paper and the core board without manual adjustment, saving manpower and having a high degree of automation, which can effectively improve the preparation efficiency of the carbon crystal heating plate and is more suitable for the industrial production of flame-retardant carbon crystal heating plates.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment 1

[0041] The present invention provides as Figure 1-6A preparation method of a flame-retardant carbon crystal heating plate is shown. The preparation method of the flame-retardant carbon crystal heating plate is realized by a carbon crystal heating plate manufacturing device. The carbon crystal heating plate manufacturing device includes a housing 1. A limiting plate 11 is fixedly arranged at the top inside the housing 1. A first driving mechanism 2 is fixedly arranged at the bottom inside the housing 1. A second driving mechanism 3 is arranged on the top of the first driving mechanism 2. Two groups of clamping and positioning mechanisms 4 are arranged inside the second driving mechanism 3. Paper laying mechanisms 5 are arranged on both sides of the top of the housing 1. Two groups of hot pressing and cutting mechanisms 6 are arranged at the top inside the housing 1.

[0042] As Figure 2 shown, the first driving mechanism 2 includes a reciprocating screw 21, a driving motor 22, an inner sleeve 23, a first spring 24, an outer sleeve 25, a first outer plate 26 and a trigger rod 27. Among them, the reciprocating screw 21 penetrates through the housing 1 and is rotatably connected to the housing 1 through a bearing. The driving motor 22 is fixedly arranged at the bottom of the housing 1 and is in transmission connection with the reciprocating screw 21. The inner sleeve 23, the first spring 24 and the outer sleeve 25 are sleeved on the outer side of the reciprocating screw 21 in sequence from top to bottom. The inner sleeve 23 is slidably connected to the reciprocating screw 21. The first spring 24 is fixedly connected between the inner sleeve 23 and the outer sleeve 25. The outer sleeve 25 is slidably sleeved on the outer side of the inner sleeve 23 and is in transmission connection with the reciprocating screw 21. The first outer plate 26 is fixedly sleeved on the top of the outer sleeve 25. The trigger rod 27 is fixedly arranged on the top of the first outer plate 26.

[0043] As Figure 3 shown, the second driving mechanism 3 includes a lifting plate 31, a positioning groove 32, a second outer plate 33, a rack 34 and a limiting block 35. Among them, the lifting plate 31 is fixedly arranged on the top of the inner sleeve 23. The positioning groove 32 is opened on the top of the lifting plate 31. The second outer plate 33 is fixedly sleeved on the bottom of the lifting plate 31. The rack 34 is fixedly arranged on the top of the second outer plate 33. The limiting block 35 is located directly above the second outer plate 33 and is fixedly connected to the inner wall of the housing 1.

[0044] By setting the above structure, it is convenient for the driving motor 22 to drive the reciprocating screw 21 to rotate continuously after starting. When the reciprocating screw 21 rotates, it drives the outer sleeve 25 to rise continuously. When the outer sleeve 25 rises, it drives the lifting plate 31 to rise through the first spring 24 and the inner sleeve 23, and drives the trigger rod 27 to rise through the first outer plate 26. When the lifting plate 31 rises, it drives the core plate to rise, and at the same time drives the rack 34 to rise through the second outer plate 33. Subsequently, when the top of the second outer plate 33 fits against the bottom of the limit block 35, both the core plate and the mica paper reach the hot pressing station. The top end of the core plate fits against the bottom end of the limit plate 11. At the same time, due to the limitation of the limit block 35, the second outer plate 33, the lifting plate 31 and the inner sleeve 23 cannot continue to rise. Subsequently, as the reciprocating screw 21 continues to rotate, the outer sleeve 25 drives the trigger rod 27 to continue to rise through the first outer plate 26.

[0045] As Figure 3 shown in Figure 4 Figure, the clamping and positioning mechanism 4 includes a stop block 41, a guide rod 42, a positioning clamping plate 43, an inclined surface push block 44, a baffle plate 45 and a second spring 46. Among them, the stop block 41 is located inside the lifting plate 31. The guide rod 42 slidably penetrates the stop block 41 and is fixedly connected to the inner wall of the lifting plate 31. The positioning clamping plate 43 is slidably nested inside the positioning groove 32 and extends into the lifting plate 31. The inclined surface push block 44 and the baffle plate 45 are fixedly arranged on the inner side of the positioning clamping plate 43 from top to bottom in sequence. The second spring 46 is fixedly connected between the outer side of the positioning clamping plate 43 and the inner wall of the lifting plate 31.

[0046] By setting the above structure, during the rising process of the lifting plate 31, the reciprocating screw 21 relatively descends inside the lifting plate 31, thereby gradually releasing the jacking of the stop block 41. As the stop block 41 continuously descends, the stop block 41 gradually releases the blockage of the baffle plate 45. The compressed second spring 46 pushes the positioning clamping plate 43 to move towards the direction close to the core plate. During the movement of the positioning clamping plate 43, the inclined surface push block 44 moves synchronously, thereby gradually jacking up the core plate. Subsequently, when the positioning clamping plate 43 fits against the core plate and completes the clamping and positioning of the core plate, the core plate is pushed out from the inside of the positioning groove 32 by the inclined surface push block 44.

[0047] As Figure 5 shown in

[0048] By setting the above structure, when the rack 34 rises, it drives the gear 55 to rotate, and then the gear 55 drives the winding roller 52 to rotate synchronously. When the winding roller 52 rotates, it continuously outputs the mica paper tape 54, so that the mica paper tape 54 gradually reaches the hot pressing station. During the subsequent downward reset process of the gear 55, due to the existence of the overrunning clutch between the gear 55 and the winding roller 52, the gear 55 rotates while the winding roller 52 does not rotate.

[0049] As Figure 6 shown, the hot pressing and cutting mechanism 6 includes side plates 61, sliding plates 62, trigger grooves 63, hot pressing plates 64, third springs 65, cutting knives 66, end plates 67 and fourth springs 68. Among them, the side plates 61 are fixedly connected to the inner wall of the housing 1, the sliding plates 62 are slidably arranged through the bottom of the side surfaces of the side plates 61, the trigger grooves 63 are opened at the bottoms of the sliding plates 62, the hot pressing plates 64 are fixedly arranged at the ends of the sliding plates 62, the third springs 65 are sleeved outside the sliding plates 62 and fixedly connected between the side plates 61 and the hot pressing plates 64, the cutting knives 66 are slidably arranged through the tops of the side surfaces of the side plates 61, the end plates 67 are fixedly arranged at the tops of the cutting knives 66, and the fourth springs 68 are fixedly connected between the side plates 61 and the end plates 67.

[0050] By setting the above structure, after the trigger rod 27 fits with the inner wall of the trigger groove 63, as the outer sleeve 25 continuously moves upward, the trigger rod 27 pushes the sliding plate 62 through the trigger groove 63, so that the sliding plate 62 drives the hot pressing plate 64 to move and stretches the third spring 65 at the same time until the hot pressing plate 64 presses the mica paper against the side of the core plate, and then the hot pressing operation starts. When the trigger rod 27 fits with the cutting knife 66, as the outer sleeve 25 continues to rise, the trigger rod 27 pushes the cutting knife 66 to move, and at the same time makes the cutting knife 66 compress the fourth spring 68 through the end plate 67 until the cutting knife 66 cuts off the mica paper tape 54 at the joint of the core plate and the limiting plate 11.

[0051] Embodiment 2

[0052] The method specifically includes the following steps:

[0053] S1. Insert the core plate into the inner side of the positioning groove 32. The core plate is kept vertical inside the positioning groove 32. Start the driving motor 22. After the driving motor 22 starts, it drives the reciprocating screw rod 21 to continuously rotate. When the reciprocating screw rod 21 rotates, it drives the outer sleeve 25 to continuously rise. When the outer sleeve 25 rises, it drives the lifting plate 31 to rise through the first spring 24 and the inner sleeve 23, and drives the trigger rod 27 to rise through the first outer plate 26;

[0054] S2, when the lifting plate 31 rises, it drives the core plate to rise, and at the same time drives the rack 34 to rise through the second outer sleeve plate 33, and when the rack 34 rises, it drives the gear 55 to rotate, and then the gear 55 drives the winding roller 52 to rotate synchronously, and when the winding roller 52 rotates, the mica paper tape 54 is continuously output, so that the mica paper tape 54 gradually reaches the hot pressing station;

[0055] S3, during the lifting process of the lifting plate 31, the reciprocating screw 21 relatively descends inside the lifting plate 31, thereby gradually releasing the lifting of the stopper 41. As the stopper 41 continues to descend, the stopper 41 gradually releases the blocking of the stopper 45, and the compressed second spring 46 pushes the positioning clamping plate 43 to move toward the core plate. During the movement of the positioning clamping plate 43, the inclined push block 44 moves synchronously, thereby gradually lifting the core plate.

[0056] S4, when the rising distance of the outer sleeve 25 reaches the first threshold, the positioning clamping plate 43 is fitted with the core plate, and the core plate is moved out from the inner side of the positioning groove 32 under the push of the inclined push block 44. When the rising distance of the outer sleeve 25 reaches the second threshold, the top of the second outer sleeve 33 is fitted with the bottom of the limit block 35. At this time, the core plate and the mica paper have arrived at the hot pressing station, and the top of the core plate is fitted with the bottom of the limit plate 11. At the same time, due to the limitation of the limit block 35, the second outer sleeve 33, the lifting plate 31 and the inner sleeve 23 cannot continue to rise. Subsequently, as the reciprocating screw 21 continues to rotate, the outer sleeve 25 drives the trigger rod 27 to continue to rise through the first outer sleeve 26;

[0057] S5, when the outer sleeve 25 rises to a third threshold, the trigger rod 27 fits against the inner wall of the trigger slot 63. As the outer sleeve 25 continues to move upward, the trigger rod 27 pushes the sliding plate 62 through the trigger slot 63, so that the sliding plate 62 drives the hot pressing plate 64 to move and stretches the third spring 65 at the same time;

[0058] S6, when the outer sleeve 25 rises to a fourth threshold, the hot pressing plate 64 presses the mica paper against the side of the core plate, and then starts the hot pressing operation. When the outer sleeve 25 rises to a fifth threshold, the trigger rod 27 fits with the cutter 66. Subsequently, as the outer sleeve 25 continues to rise, the trigger rod 27 pushes the cutter 66 to move, and at the same time, the cutter 66 compresses the fourth spring 68 through the end plate 67.

[0059] S7, when the rising distance of the outer sleeve 25 reaches the sixth threshold, the cutter 66 cuts off the mica paper tape 54 at the joint of the core plate and the limit plate 11. When the rising distance of the outer sleeve 25 reaches the seventh threshold, the outer sleeve 25 moves to the top of the reciprocating thread outside the reciprocating screw 21. Subsequently, as the reciprocating screw 21 continues to rotate, the outer sleeve 25 moves down and resets.

[0060] S8. As the outer sleeve 25 continues to move downward, the hot pressing and cutting mechanism 6, the clamping and positioning mechanism 4, and the second driving mechanism 3 are reset successively. During the downward reset process of the rack 34 in the second driving mechanism 3, due to the existence of the overrunning clutch between the gear 55 and the winding roller 52, the gear 55 rotates while the winding roller 52 does not rotate.

[0061] S9. When the downward movement distance of the outer sleeve 25 reaches the eighth threshold, the outer sleeve 25 moves to the lowest end of the reciprocating thread on the outside of the reciprocating screw 21 and reaches the initial station at the same time. At this time, manually remove the carbon crystal heating plate formed after hot pressing and stop the driving motor 22.

[0062] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.

8. The method for preparing a flame retardant carbon crystal heating plate according to claim 7, characterized in that: The method specifically comprises the following steps: S1, insert the core plate into the inner side of the positioning groove (32), keep the core plate in a vertical state inside the positioning groove (32), start the driving motor (22), and after the driving motor (22) is started, the reciprocating screw (21) is driven to rotate continuously, and the reciprocating screw (21) drives the outer sleeve (25) to rise continuously when rotating, and when the outer sleeve (25) rises, the lifting plate (31) is driven to rise through the first spring (24) and the inner sleeve (23), and the trigger rod (27) is driven to rise through the first outer sleeve (26); S2, when the lifting plate (31) rises, it drives the core plate to rise, and at the same time drives the rack (34) to rise through the second outer sleeve plate (33), and when the rack (34) rises, it drives the gear (55) to rotate, and then the gear (55) drives the winding roller (52) to rotate synchronously, and when the winding roller (52) rotates, the mica paper tape (54) is continuously output, so that the mica paper tape (54) gradually reaches the hot pressing station; S3, during the lifting process of the lifting plate (31), the reciprocating screw (21) relatively descends inside the lifting plate (31), thereby gradually releasing the lifting of the stopper (41). As the stopper (41) continues to descend, the stopper (41) gradually releases the blocking of the baffle (45), and the compressed second spring (46) pushes the positioning clamp (43) to move in the direction close to the core plate. During the movement of the positioning clamp (43), the inclined push block (44) moves synchronously, thereby gradually lifting the core plate; S4, when the rising distance of the outer sleeve (25) reaches the first threshold, the positioning clamp (43) fits with the core plate, and at the same time, the core plate moves out from the inner side of the positioning groove (32) under the push of the inclined push block (44), and when the rising distance of the outer sleeve (25) reaches the second threshold, the top of the second outer sleeve (33) fits with the bottom of the limit block (35). At this time, the core plate and the mica paper both arrive at the hot pressing station, and the top of the core plate fits with the bottom of the limit plate (11). At the same time, due to the limitation of the limit block (35), the second outer sleeve (33), the lifting plate (31) and the inner sleeve (23) cannot continue to rise. Subsequently, as the reciprocating screw (21) continues to rotate, the outer sleeve (25) drives the trigger rod (27) to continue to rise through the first outer sleeve (26); S5, when the rising distance of the outer sleeve (25) reaches the third threshold value, the trigger rod (27) fits against the inner wall of the trigger groove (63), and as the outer sleeve (25) continues to move upward, the trigger rod (27) pushes the sliding plate (62) through the trigger groove (63), so that the sliding plate (62) drives the hot pressing plate (64) to move and stretches the third spring (65) at the same time; S6, when the outer sleeve (25) rises to a fourth threshold, the hot pressing plate (64) presses the mica paper against the side of the core plate, thereby starting the hot pressing operation; when the outer sleeve (25) rises to a fifth threshold, the trigger rod (27) fits the cutter (66), and subsequently, as the outer sleeve (25) continues to rise, the trigger rod (27) pushes the cutter (66) to move, and at the same time, the cutter (66) compresses the fourth spring (68) through the end plate (67); S7, when the rising distance of the outer sleeve (25) reaches the sixth threshold, the cutter (66) cuts off the mica paper tape (54) at the joint between the core plate and the limit plate (11), and when the rising distance of the outer sleeve (25) reaches the seventh threshold, the outer sleeve (25) moves to the top of the reciprocating thread on the outer side of the reciprocating screw (21), and then as the reciprocating screw (21) continues to rotate, the outer sleeve (25) moves downward and resets; S8, as the outer sleeve (25) continues to move downward, the hot pressing and cutting mechanism (6), the clamping and positioning mechanism (4) and the second driving mechanism (3) are reset successively. During the downward reset process of the rack (34) in the second driving mechanism (3), due to the existence of an overrunning clutch between the gear (55) and the winding roller (52), the gear (55) rotates, while the winding roller (52) does not rotate; S9, when the downward movement distance of the outer sleeve (25) reaches the eighth threshold value, the outer sleeve (25) moves to the lowest end of the reciprocating thread outside the reciprocating screw (21) and reaches the initial working position at the same time. At this time, the carbon crystal heating plate formed after hot pressing is manually removed and the driving motor (22) is stopped.
