Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Although the cold pressing process is essentially carried out at room temperature, it does not involve high temperature or complex chemical reactions, and therefore does not produce harmful gases, ensuring the cleanliness and safety of the production environment. However, in the manufacturing process of the carbon crystal heating plate, if the curing process of the resin or the use of additives is involved, when the heating plate is cold pressed, it is possible to release harmful gases or produce unpleasant irritating odors, which will have a certain impact on the personal safety of the staff. When this embodiment is used, the heating plate is laid flat on the surface of the lower mold 3, and the drive module is started (the drive module is a prior art, and in the article it plays the function of driving the upper mold 1 to move downward. It has not been shown in the article and will not be elaborated on). The drive module is connected to the The connecting rod 2 drives the upper mold 1 to move downward, and when the upper mold 1 passes through the sealing plate 6, the upper mold 1 contacts the heating plate; at this time, the motor 10 is started, and the motor 10 drives the transmission mechanism to operate when it is running, and the transmission mechanism drives the spur gear 9 to rotate when it is running, and the rotation of the spur gear 9 drives the first rack 7 and the second rack 8 to move in a direction close to each other, and the movement of the first rack 7 and the second rack 8 drives a pair of sealing plates 6 to approach and squeeze them together, and then the operation of the motor 10 is stopped, and the pair of sealing plates 6 remain stationary after being fitted; at this time, when the upper mold 1 squeezes the heating plate, the gas generated will be isolated inside the processing table 4 and cannot be transmitted, thereby preventing the staff from inhaling the irritating smell generated by the squeezing.

[0023] like Figure 2 and Figure 3As shown, the transmission mechanism also includes a first bevel gear 11, a second bevel gear 12, a fixed rod 13 and a pair of limit rods 14. The first bevel gear 11 is fixedly connected to the outer side of the output end of the motor 10, the second bevel gear 12 is meshed with the first bevel gear 11, the fixed rod 13 is fixedly connected to the inside of the second bevel gear 12, the pair of limit rods 14 are both rotatably connected to the outer side of the fixed rod 13, and the ends of the pair of limit rods 14 away from the fixed rod 13 are fixedly connected to the inner wall of the processing table 4.

[0024] When the motor 10 is running, it will drive the first bevel gear 11 to rotate, and the rotation of the first bevel gear 11 will drive the second bevel gear 12 to rotate. The rotation of the second bevel gear 12 will drive the spur gear 9 to rotate through the fixed rod 13. When the spur gear 9 rotates, it will drive the first rack 7 and the second rack 8 to move closer or farther away, thereby driving a pair of sealing plates 6 to move closer or farther away.

[0025] like Figure 2 , Figure 3 and Figure 5 As shown, ventilation grooves are provided at the top ends of the pair of fixed plates 5, and a vacuum pump 15 is installed inside the ventilation grooves. An air supply pipe is installed at the top ends of the ventilation grooves, and the air supply pipe is used to transport the gas inside the processing table 4. A sealing strip 16 is glued to the ends of the pair of sealing plates 6 that are close to each other.

[0026] When the internal air of the processing table 4 contains irritating gas, the vacuum pump 15 inside the ventilation slot is started (the vacuum pump 15 is a prior art and the technology is mature, so it will not be elaborated in detail in the article). When the vacuum pump 15 is running, the air inside the processing table 4 is extracted, and the irritating gas is transported to the designated position through the air pipe. The air pipe has not been shown in the article. The air pipe is a single gas delivery pipeline and will not be elaborated in detail in the article. The setting of the sealing strip 16 can increase the sealing performance when a pair of sealing plates 6 are fitted together.

[0027] like Figure 2 and Figure 4 As shown, a bidirectional screw 17 is rotatably connected to the inner wall of the processing table 4, and two ends of a pair of the bidirectional screws 17 are provided with external threads in different directions. A pair of threaded blocks 18 are sleeved on the outer side of the bidirectional screw 17, and a slider is fixedly connected to the inner side of the pair of threaded blocks 18. The slider is threadedly connected to the outer side of the bidirectional screw 17. A guide rod 19 is fixedly connected to the inner wall of the processing table 4, and the guide rod 19 passes through a pair of threaded blocks 18. A support rod 20 is hinged between the threaded block 18 and the lower mold 3. A linkage mechanism is arranged between the bidirectional screw 17 and the motor 10, and the linkage mechanism is used to drive the lower mold 3 up and down. The linkage mechanism includes a first sprocket 22, and the first sprocket 22 is fixedly connected to the outer side of the output end of the motor 10.

[0028] In order to facilitate the staff to take the heating plate at the top of the lower mold 3, when the present embodiment is in use, in the initial state, the lower mold 3 is located in a position close to the top inside the processing table 4. At this time, the heating plate can be conveniently taken out. When the motor 10 is running, it means that the upper mold 1 needs to be close to the lower mold 3 to squeeze the heating plate. At this time, in order to prevent the lower mold 3 from blocking the moving path of the sealing plate 6 when the pair of sealing plates 6 are close to each other, the motor 10 will drive the first sprocket 22 to rotate, and the rotation of the first sprocket 22 will drive the linkage mechanism to operate, and the operation of the linkage mechanism will drive the bidirectional screw 17 to rotate, and the rotation of the bidirectional screw 17 will drive the pair of sliders to move, and the movement of the pair of sliders will drive the threaded block 18 on the outside to move, and the threaded block 18 The movement will drive the support rod 20 to swing, and the support rod 20 can pull the lower mold 3 downward when swinging, thereby avoiding the situation of blocking the movement of a pair of sealing plates 6, and the setting of the guide rod 19 can limit the threaded block 18, so that the threaded block 18 moves along the outer side of the guide rod 19 when moving, making its movement more stable and avoiding shaking. When the lower mold 3 needs to rise, it means that the upper mold 1 has finished extruding the heating plate, the motor 10 runs in reverse, and the linkage mechanism runs in reverse, so that the bidirectional screw 17 rotates in the opposite direction, and the support rod 20 finally swings in the opposite direction, presenting a vertical shape, and returns to the initial position. At this time, the support rod 20 will push the lower mold 3 to reset, and lift the processed heating plate to facilitate its removal.

[0029] like Figure 2 and Figure 4 As shown, the linkage mechanism further includes a chain 21 and a second sprocket 23 . The second sprocket 23 is fixedly connected to the outer side of the bidirectional screw 17 . The chain 21 is meshed between the first sprocket 22 and the second sprocket 23 .

[0030] When the motor 10 is running, it drives the first sprocket 22 to rotate, and the rotation of the first sprocket 22 drives the second sprocket 23 to rotate through the chain 21. Since the second sprocket 23 is fixed to the outer side of the bidirectional screw 17, the bidirectional screw 17 can be driven to rotate when the second sprocket 23 rotates.

[0031] Working principle: Although the cold pressing process is essentially carried out at room temperature, it does not involve high temperature or complex chemical reactions, and therefore does not produce harmful gases, ensuring the cleanliness and safety of the production environment. However, in the manufacturing process of the carbon crystal heating plate, if the curing process of the resin or the use of additives is involved, when the heating plate is cold pressed, it is possible to release harmful gases or produce unpleasant irritating odors, which will have a certain impact on the personal safety of the staff. When this embodiment is used, the heating plate is laid flat on the surface of the lower mold 3, and the drive module is started (the drive module is a prior art, and in the article it plays the function of driving the upper mold 1 to move downward. It has not been shown in the article and will not be elaborated on). The drive module The upper mold 1 is driven downward by the connecting rod 2, and when the upper mold 1 passes through the sealing plate 6, the upper mold 1 contacts the heating plate; at this time, the motor 10 is started, and the motor 10 drives the transmission mechanism to operate, and the transmission mechanism drives the spur gear 9 to rotate when it is in operation, and the rotation of the spur gear 9 drives the first rack 7 and the second rack 8 to move in a direction close to each other, and the movement of the first rack 7 and the second rack 8 drives a pair of sealing plates 6 to approach and squeeze and contact together, and then the operation of the motor 10 is stopped, and the pair of sealing plates 6 remain stationary after being fitted; at this time, when the upper mold 1 squeezes the heating plate, the gas generated will be isolated inside the processing table 4 and cannot be transmitted, thereby preventing the staff from inhaling the irritating smell generated by the squeezing;

[0032] When the motor 10 is running, it drives the first bevel gear 11 to rotate, and the rotation of the first bevel gear 11 drives the second bevel gear 12 to rotate, and the rotation of the second bevel gear 12 drives the spur gear 9 to rotate through the fixing rod 13, and when the spur gear 9 rotates, it drives the first rack 7 and the second rack 8 to move closer or farther, thereby driving the pair of sealing plates 6 to move closer or farther;

[0033] When the internal air of the processing table 4 contains irritating gas, the vacuum pump 15 inside the ventilation slot is started (the vacuum pump 15 is a prior art, and the technology is mature, and no further explanation is given in the article). The vacuum pump 15 extracts the air inside the processing table 4 during operation, and delivers the irritating gas to a designated location through an air delivery pipe. The air delivery pipe is not shown in the article, and is a single gas delivery pipe, and no further explanation is given in the article. The setting of the sealing strip 16 can increase the sealing performance of a pair of sealing plates 6 when they are fitted together.

[0034] In order to facilitate the staff to take the heating plate at the top of the lower mold 3, when the present embodiment is in use, in the initial state, the lower mold 3 is located in a position close to the top inside the processing table 4. At this time, the heating plate can be conveniently taken out. When the motor 10 is running, it means that the upper mold 1 needs to be close to the lower mold 3 to squeeze the heating plate. At this time, in order to prevent the lower mold 3 from blocking the moving path of the sealing plate 6 when the pair of sealing plates 6 are close to each other, the motor 10 will drive the first sprocket 22 to rotate, and the rotation of the first sprocket 22 will drive the linkage mechanism to operate, and the operation of the linkage mechanism will drive the bidirectional screw 17 to rotate, and the rotation of the bidirectional screw 17 will drive the pair of sliders to move, and the movement of the pair of sliders will drive the threaded block 18 on the outside to move, and the threaded block 18 The movement will drive the support rod 20 to swing, and the support rod 20 can pull the lower mold 3 to move downward when swinging, thereby avoiding the situation of blocking the movement of a pair of sealing plates 6, and the setting of the guide rod 19 can limit the threaded block 18, so that the threaded block 18 moves along the outer side of the guide rod 19 when moving, making its movement more stable and avoiding shaking. When the lower mold 3 needs to rise, it means that the upper mold 1 has finished squeezing the heating plate, the motor 10 runs in the reverse direction, and the linkage mechanism runs in the reverse direction, so that the bidirectional screw 17 rotates in the reverse direction, and the support rod 20 finally swings in the reverse direction, presenting a vertical shape, and returns to the initial position. At this time, the support rod 20 will push the lower mold 3 to reset, and lift the processed heating plate to facilitate its removal;

[0035] When the motor 10 is running, it drives the first sprocket 22 to rotate, and the rotation of the first sprocket 22 drives the second sprocket 23 to rotate through the chain 21. Since the second sprocket 23 is fixed to the outer side of the bidirectional screw 17, the bidirectional screw 17 can be driven to rotate when the second sprocket 23 rotates.

[0036] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
