[0034] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] As Figure 1 and Figure 2As shown in the figure, the pressing plate 10 includes a plate body 1, a first plug 2, a first connecting member 3, and a plurality of first blocking members 4; a first hole 11 is provided on the plate body 1; the first connecting member 3 is arranged in the first hole 11 and has a gap with the side wall of the first hole 11, so that the fluid in the first hole 11 can flow along its axial direction between the side wall of the first hole 11 and the first connecting member 3; along the axial direction of the first hole 11, the first blocking members 4 are arranged at intervals in the first hole 11; each first blocking member 4 is used to block the first hole 11, and at least two first blocking members 4 are connected to the first connecting member 3, and the gap between two adjacent first blocking members 4 is used for the fluid to pass through; the first plug 2 is detachably connected to the plate body 1 and closes the first hole 11; in the axial direction of the first hole 11, the first connecting member 3 and each first blocking member 4 are both located on the same side of the first plug 2, and the first connecting member 3 and each first blocking member 4 can both move out of the first hole 11 along the direction from the first connecting member 3 to the first plug 2.

[0036] Among them, a part of the first hole 11 is a part of the flow channel in the plate body 1, and the first blocking member 4 is used to adjust the flow direction of the fluid in the plate body 1; the first plug 2 is used to close the first hole 11 to prevent the fluid from leaking from the opening of the first hole 11. In addition, the fluid can be liquid or gas.

[0037] In the prior art, the pressing plate 10 also has the above-mentioned related settings such as the plate body 1, the first plug 2, and the first blocking member 4. However, in the prior art, the first plug 2 and the plate body 1 are usually welded together, resulting in the first blocking member 4 being unable or difficult to be taken out from the flow channel. When cleaning the flow channel, only corresponding operations can be carried out from the opening formed by the flow channel on the plate body 1, and it is very difficult to effectively clean the inside of the flow channel, so that when the flow channel is blocked by foreign matters, the pressing plate 10 can only be replaced as a whole. In this embodiment, the first plug 2 is detachably connected to the plate body 1. When the flow channel of the plate body 1 is blocked, the first plug 2 can be disassembled, so that the first connecting member 3 and the first blocking member 4 can be taken out from the first hole 11, which is convenient for cleaning the foreign matters in the flow channel, making the maintenance and repair of the pressing plate 10 simpler and more convenient. When the flow channel in the pressing plate 10 is blocked by foreign matters, the foreign matters can be conveniently cleaned without replacing the pressing plate 10 as a whole, thereby reducing the use cost.

[0038] At the same time, at least two first blocking members 4 are connected to the first connecting member 3. When the first connecting member 3 is taken out, at least two first blocking members 4 can be taken out at the same time, so that the maintenance and repair of the pressing plate 10 can be more convenient.

[0039] It should be noted that except for the detachable connection between the first plug 2 and the plate body 1 and the settings related to the first connecting member 3, the other settings in the above embodiment can be existing designs.

[0040] There is a gap between the first connecting member 3 and the side wall of the first hole 11 to prevent the first connecting member 3 from blocking the fluid from flowing along the axial direction of the first hole 11.

[0041] The first plugging member 4 plugs the first hole 11 in two cases: Case 1, the first plugging member 4 completely seals the first hole 11; Case 2, the first plugging member 4 does not completely seal the first hole 11. During operation, the fluid can flow between two adjacent first plugging members 4.

[0042] In Case 1, when the fluid flows along the axial direction of the first hole 11 to a certain first plugging member 4, it cannot pass through the first plugging member 4. In Case 2, when the fluid flows along the axial direction of the first hole 11 to a certain first plugging member 4, it can pass through the first plugging member 4 and continue to flow, but due to the setting of the first plugging member 4, it will have an obstructive effect on the fluid.

[0043] In addition, the opening of the first hole 11 refers to the opening formed by the first hole 11 on the outer surface of the plate body 1 (defining this opening as the first opening). The purpose of setting the first plug 2 is to block the fluid from flowing out of the plate body 1 from the first opening. The first connecting member 3 and the first plugging member 4 can be removed from the first hole 11 from the first opening, and at the same time, the first connecting member 3 and the first plugging member 4 can also be placed into the first hole 11 from the first opening.

[0044] The relative position between the first plug 2 and the plate body 1 has the following scenarios: Scenario 1, the first plug 2 is completely located outside the first hole 11; Scenario 2, the first plug 2 is completely located inside the first hole 11; Scenario 3, a part of the first plug 2 is located inside the first hole 11, and another part of the first plug 2 is located outside the first hole 11.

[0045] In Scenario 1, the first plug 2 can completely cover the first opening to achieve the closure of the first hole 11.

[0046] In Scenario 2, the first plug 2 and the side wall of the first hole 11 are hermetically connected, thereby achieving the closure of the first hole 11.

[0047] In Scenario 3, the part of the first plug 2 located outside the first hole 11 can completely cover the first opening to achieve the closure of the first hole 11; and / or, the part of the first plug 2 located inside the first hole 11 and the side wall of the first hole 11 are hermetically connected, thereby achieving the closure of the first hole 11.

[0048] Such as Figure 1 and Figure 2As shown, in one embodiment, the first hole 11 is a blind hole. At this time, only one first opening is formed on the outer surface of the plate body 1 for the first hole 11. Moreover, in the axial direction of the first hole 11, the first connecting member 3 and each first plugging member 4 are both located between the first plug 2 and the bottom surface of the first hole 11. In this embodiment, the hole wall of the first hole 11 has a side wall and a bottom wall. Among them, the side wall is the part of the hole wall in the radial direction of the first hole 11, the bottom wall is the part of the hole wall in the axial direction of the first hole 11, and the bottom surface of the first hole 11 is the surface of its bottom wall.

[0049] In one embodiment, the first hole 11 is a circular hole, that is, the cross-section of the first hole 11 is circular. Of course, the cross-section of the first hole 11 can also be other shapes, such as square, trapezoidal, etc.

[0050] In one embodiment, the first plug 2 is threadedly connected to the first hole 11, thereby realizing the detachable connection between the first plug 2 and the plate body 1.

[0051] In this embodiment, the area where the first hole 11 cooperates with the first plug 2 is provided with internal threads. The first plug 2 has a first section structure and a second section structure. The first section has external threads, which can be threadedly mated with the first hole 11, and the second section structure can abut against the plate body 1. In addition, the first plug 2 further includes a sealing structure. After assembly, the sealing structure is clamped between the second section structure and the plate body 1 to improve the sealing effect of the first plug 2 on the first hole 11.

[0052] Among them, the first section structure and the second section structure form a bolt. The first section structure is the stud part of the bolt, and the second section structure is the bolt head part of the bolt. The sealing structure can be a sealing ring, and the sealing ring can be a rubber ring, which is sleeved on the first section structure.

[0053] In one embodiment, each first plugging member 4 is connected to the first connecting member 3. In this way, when the first connecting member 3 is taken out from the first hole 11, all the first plugging members 4 can be taken out from the first hole 11, so that the pressing plate 10 can be maintained more conveniently.

[0054] In one embodiment, the first connecting member 3 is a connecting rod. The connecting rod has a certain hardness. During work, the corresponding first plugging member 4 can be first connected to the first connecting member 3 and their relative positions are made appropriate. In this way, when the first connecting member 3 is inserted into the appropriate position of the first hole 11, the first plugging members 4 on it can be installed in the appropriate positions of the first hole 11, so that the pressing plate 10 can be maintained more conveniently.

[0055] The first connecting member 3 can be made of metal materials, such as steel, iron, aluminum, etc. In addition, the first connecting member 3 can be a cylindrical structure, that is, its cross-section is circular. Of course, the cross-section of the first connecting member 3 can also be other shapes, such as square, trapezoidal, etc.

[0056] In one embodiment, in the radial direction of the first hole 11, the first plugging member 4 protrudes from the first connecting member 3, so that on the premise of ensuring the blocking effect of the first plugging member 4 on fluid flow, the blocking of the first connecting member 3 on fluid flow can be reduced.

[0057] In one embodiment, the first plugging member 4 can be made of a metal material, such as steel, iron, aluminum, etc. In addition, the first plugging member 4 can be a cylindrical structure, that is, its cross-section is circular. Of course, the cross-section of the first plugging member 4 can also be other shapes, such as square, trapezoidal, etc.

[0058] In one embodiment, the first connecting member 3 is coaxially arranged with the first hole 11, and the diameter of the first connecting member 3 is smaller than the diameter of the first hole 11.

[0059] In one embodiment, the first plugging member 4 is coaxially arranged with the first connecting member 3, and the diameter of the first plugging member 4 is larger than the diameter of the first connecting member 3.

[0060] Among them, the first plugging member 4 is in clearance fit with the first hole 11, which is more convenient for the installation and removal of the first plugging member 4 in the first hole 11.

[0061] In one embodiment, in addition, the unilateral distance between the first connecting member 3 and the side wall of the first hole 11 is L1, where 0 < L1 ≤ 10 mm. Specifically, L1 can be 5 mm, 7 mm, 9 mm, etc.

[0062] The unilateral distance between the first plugging member 4 and the side wall of the first hole 11 is L2, 0 ≤ L2 ≤ 0.1 mm. Specifically, L1 can be 0.01 mm, 0.02 mm, 0.03 mm, 0.05 mm, etc.

[0063] In one embodiment, the first plugging member 4 has a perforation, and the first connecting member 3 is inserted into the perforation, that is, the first plugging member 4 is sleeved on the first connecting member 3. The first connecting member 3 and the first plugging member 4 are fixedly connected to prevent the first plugging member 4 from moving relative to the first connecting member.

[0064] Among them, the first connecting member 3 and the first plugging member 4 can be an integral structure. Specifically, the first connecting member 3 and the first plugging member 4 can be welded together to form an integral body. Or, they can also be integrally formed by casting or other methods.

[0065] In one embodiment, when the first plugging member 4 is in clearance fit with the first hole 11, each first connecting member 3 and the first plugging member 4 are connected to form a blocking structure.

[0066] When the first hole 11 is a blind hole, in the axial direction of the first hole 11, the blocking structure is located between the first plug 2 and the bottom surface of the first hole 11, and the distance between at least one of the first plug 2 and the bottom surface of the first hole 11 and the blocking structure is L3, where 0 ≤ L3 ≤ 0.2 mm. In this way, the position of the blocking structure in the first hole 11 can be kept stable, and the positions of the first sealing members 4 in the first hole 11 are also made stable.

[0067] Normally, in the axial direction of the first hole 11, among the entire blocking structure, the first connecting member 3 is closest to the first plug 2 and also closest to the bottom surface of the first hole 11.

[0068] Moreover, normally, the first connecting member 3 abuts against the bottom surface of the first hole 11, and the distance therebetween is 0 at this time. Meanwhile, the first connecting member 3 and the first plug 2 are arranged at intervals. During assembly, when the blocking structure is inserted into the first hole 11 until it abuts against the bottom surface of the first hole 11, it indicates that the blocking structure is installed in place, and the arrangement of the first connecting member 3 and the first plug 2 at intervals can facilitate the installation of the first plug 2.

[0069] Certainly, in some embodiments, both ends of the blocking structure can respectively abut against the first plug 2 and the bottom surface of the first hole 11. In this embodiment, both ends of the first connecting member 3 can respectively abut against the first plug 2 and the bottom surface of the first hole 11. At this time, each first sealing member 4 is spaced from both the first plug 2 and the bottom surface of the first hole 11.

[0070] As Figure 1 shown, in one embodiment, the pressing plate 10 further includes a second plug 5 and a third plug 6; the plate body 1 is further provided with a second hole 12 and a plurality of third holes 13; the second hole 12 and the first hole 11 are spaced in a first direction; each of the third holes 13 is spaced in a second direction, where the first direction and the second direction intersect; both ends of each of the third holes 13 are respectively communicated with the first hole 11 and the second hole 12; the second plug 5 is connected to the plate body 1 and closes the second hole 12; the third plug 6 is connected to the plate body 1 and closes a part of the third holes 13; in the second direction, each of the third holes 13 is located on the same side of the first plug 2 and also on the same side of the second plug 5; in the first direction, both the first hole 11 and the second hole 12 are located on the same side of the third plug 6.

[0071] Among them, the flow channel in the pressing plate 10 is jointly composed of the first hole 11, the second hole 12, and each of the third holes 13.

[0072] "Both ends of each of the third holes 13 are respectively communicated with the first hole 11 and the second hole 12" means that both ends of each third hole 13 are respectively communicated with the first hole 11 and the second hole 12. Specifically, one end of the third hole 13 extends through to the inner wall of the first hole 11, and the other end of the third hole 13 extends through to the inner wall of the second hole 12.

[0073] The second hole 12 forms a second opening on the outer surface of the plate body 1, and the third hole 13 forms a third opening on the outer surface of the plate body 1. The second plug 5 closes the second hole 12 to prevent the fluid in the flow channel from leaking out through the second opening, and the third plug 6 closes the third hole 13 to prevent the fluid in the flow channel from leaking out through the third opening.

[0074] The unclosed third hole 13 can be used to connect a pipeline outside the pressing plate 10, so as to introduce fluid into the flow channel and discharge the fluid in the flow channel.

[0075] Under normal circumstances, the number of unclosed third holes 13 is usually two. Among them, one third hole 13 is used as the fluid input hole of the flow channel, and the other third hole 13 is used as the fluid output hole of the flow channel.

[0076] In addition, in the second direction, the closed third hole 13 is located between the two unclosed third holes 13.

[0077] In addition, the unclosed third hole 13 is usually connected with a joint 20. Among them, the joint 20 and the third hole 13 can be threadedly connected, and the joint 20 is used to connect with the pipeline.

[0078] The intersection of the first direction and the second direction means that the included angle between the first direction and the second direction is greater than 0 degrees and less than 180 degrees. Preferably, the first direction and the second direction are perpendicularly arranged. Figures 1 to 4 In the illustrated example, the first direction is parallel to the X axis, and the second direction is parallel to the Y axis.

[0079] In an embodiment, the axes of the first hole 11 and the second hole 12 are parallelly arranged, and both are parallel to the second direction. The axes of the third holes 13 can be parallel to each other and are all parallel to the first direction.

[0080] Of course, in other embodiments, the axes of the first hole 11 and the second hole 12 may not be parallel, and at least two of the axes of the third holes 13 may not be parallel either.

[0081] In an embodiment, the second hole 12 can be a blind hole. At this time, only one second plug 5 is needed to close the second hole 12.

[0082] In addition, the third hole 13 can be a blind hole. At this time, only one third plug 6 is needed to close the third hole 13.

[0083] In addition, the way the second plug 5 closes the second hole 12 can be exactly the same as the direction in which the first plug 2 closes the first hole 11, and the way the third plug 6 closes the third hole 13 can be the same as the direction in which the first plug 2 closes the first hole 11.

[0084] As Figure 1 shown, in one embodiment, the pressing plate 10 further includes a second plugging member 7; the second plugging member 7 is disposed in the second hole 12 and is used to plug the second hole 12; in the second direction, the first hole 11 has a first section hole 111 located between two adjacent third holes 13, and the second hole 12 has a second section hole 121 located between two adjacent third holes 13; the first plugging member 4 is disposed in the first section hole 111, and the second plugging member 7 is disposed in the second section hole 121; in the second direction, the first section hole 111 provided with the first plugging member 4 and the second section hole 121 provided with the second plugging member 7 are adjacent and arranged alternately in sequence.

[0085] In addition, the structure of the second plugging member 7 and the structure of the first plugging member 4 may be exactly the same. The way the second plugging member 7 plugs the second hole 12 and the way the first plugging member 4 plugs the first hole 11 may be exactly the same.

[0086] As Figure 1 and Figure 3 shown, in one embodiment, the number of the second plugging members 7 is multiple, and the pressing plate 10 further includes a second connecting member 8; the second connecting member 8 is disposed in the second hole 12 and there is a gap between the second connecting member 8 and the side wall of the second hole 12, so that the fluid in the second hole 12 can flow axially between the side wall of the second hole 12 and the second connecting member 8; the second plug 5 is detachably connected to the plate body 1; each second plugging member 7 is used to plug the second hole 12, at least two second plugging members 7 are connected to the second connecting member 8, and the gap between two adjacent second plugging members 8 is used for the fluid to pass through. Wherein, the side wall of the second hole 12 is the part of the hole wall in the radial direction of the second hole 12.

[0087] When the flow channel is blocked by foreign objects, the second plug 5 can also be detached from the plate body 1, and the second plugging member 7 can be taken out from the second hole 12 to facilitate cleaning the flow channel. At the same time, at least two second plugging members 7 are connected to the second connecting member 8, so that when the second connecting member 8 is taken out, at least two second plugging members 7 can be taken out simultaneously, thereby facilitating the maintenance and repair of the pressing plate 10 more conveniently.

The cooperation mode between the second connecting member 8 and the second hole 21 and the cooperation mode between the first connecting member 3 and the first hole 11 may be exactly the same, and the connection mode between the second plugging member 7 and the second connecting member 8 and the connection mode between the first plugging member 4 and the first connecting member 3 may also be exactly the same. In addition, the second connecting member 8 and each second plugging member 7 are also connected to form a plugging structure, and the way the plugging structure maintains a stable position in the second hole 12 and the way the blocking structure maintains a stable position in the first hole 11 may be exactly the same.

[0089] The second plug 5 and the first plug 2 can be exactly the same, and the detachable connection manner between the second plug 5 and the plate body 1 and the detachable manner between the first plug 2 and the plate body 1 can be exactly the same.

[0090] In one embodiment, the third plug 6 is detachably connected to the plate body 1. Among them, the third plug 6 and the first plug 2 can also be exactly the same, and the detachable connection manner between the third plug 6 and the plate body 1 and the detachable manner between the first plug 2 and the plate body 1 can be exactly the same.

[0091] In one embodiment, a first anti-corrosion layer is provided on the outer surface of the plate body 1, which can prevent the outer surface of the plate body 1 from being corroded and improve the service life and working performance of the pressing plate 10. And / or, a second anti-corrosion layer is provided on the inner wall of the first hole 11, which can prevent the inner wall of the first hole 11 from rusting and improve the service life and working performance of the pressing plate 10.

[0092] In addition, the first anti-corrosion layer can also be a metal layer, and its material can be nickel or the like. The second anti-corrosion layer can also be a metal layer, and its material can be nickel or the like. During operation, the first anti-corrosion layer and the second anti-corrosion layer can be formed simultaneously by electroplating.

[0093] In one embodiment, in addition to the anti-corrosion layer provided on the inner wall of the first hole 11, anti-corrosion layers are also provided on the inner walls of the second hole 12 and the third hole 13. The anti-corrosion layers on the inner walls of the first hole 11, the second hole 12, and the third hole 13 can be prepared simultaneously with the first anti-corrosion layer by electroplating. The anti-corrosion layers provided on the inner walls of the second hole 12 and the third hole 13 are also the second anti-corrosion layer.

[0094] In one embodiment, the first hole 11 and the second hole 12 are both blind holes, and the first hole 11 and the second hole 12 form openings on the same side of the plate body 1; each third hole 13 is a blind hole, and each third hole 13 forms an opening on the same side of the plate body 1.

[0095] As Figures 1 to 3 shown, in one embodiment, the plate body 1 is a cuboid structure. In the first direction, the plate body 1 has a first surface 14 and a second surface 15 arranged opposite to each other; in the second direction, the plate body 1 has a third surface 16 and a fourth surface 17 arranged opposite to each other; in the third direction, the plate body 1 has a fifth surface 18 and a sixth surface 19 arranged opposite to each other. The first direction, the second direction, and the third direction are perpendicular to each other pairwise. In Figures 1 to 4 the illustrated example, the third direction is parallel to the Z axis.

[0096] When both the first hole 11 and the second hole 12 are blind holes, the first opening and the second opening can both be located on the first surface 14 or both on the second surface 15. When the third hole 13 is a blind hole, each third opening can be located on the third surface 16 or both on the fourth surface 17. Both the fifth surface 18 and the sixth surface 19 can be used to press the target product 30.

[0097] When producing the pressing plate 10, it can be produced according to the following method:

[0098] Step S1: Rough process the blank plate, specifically including rough processing the outer surface of the plate and machining internal holes in the plate; among them, the internal holes include the first hole 11, the second hole 12, and the third hole 13.

[0099] Step S2: Anneal the plate that has been rough processed to eliminate the stress generated during the rough processing.

[0100] Step S3: Process the plate that has been processed in Step S2, specifically including finish machining the outer surface of the plate and milling and boring the internal holes.

[0101] Step S4: Perform aging treatment on the finish-machined plate to further eliminate internal stress; among them, the temperature of the aging treatment is lower than the temperature of the annealing in Step S2.

[0102] Step S5: Perform chamfering, machining threaded holes, and grinding the plate surface on the plate that has undergone the aging treatment; among them, grinding the plate surface means grinding the fifth surface 18 and the sixth surface 19 to improve their flatness.

[0103] Step S6: Perform electroplating treatment on the plate that has been processed in Step S5 so as to form a first anti-corrosion layer on the outer surface of the plate and a second anti-corrosion layer on the surface of the internal holes.

[0104] Step S7: Assemble the electroplated plate (i.e., the plate body 1), the first connecting member 3, the second connecting member 8, the first plug 2, the second plug 5, the third plug 6, the first plugging member 4, and the second plugging member 7, etc. together.

[0105] It should be understood that the above relevant settings can also be replaced by other methods, such as:

[0106] In other embodiments, the first hole 11 may also be a through hole. In this case, the first hole 11 completely penetrates the plate body 1, and two first openings are formed on the outer surface of the plate body 1. In this embodiment, the number of the first plugs 2 is two, and the two first plugs 2 are respectively arranged at both ends of the first hole 11 to respectively seal both ends of the first hole 11. In addition, the first connecting member 3 and each first plugging member 4 are both located between the two first plugs 2. In this embodiment, when the two first plugs 2 are detached from the plate body 1, both of the two first openings can be used to perform the operation of moving the first connecting member 3 and the first plugging member 4 out of the first hole 11.

[0107] At this time, that the first connecting member 3 and each first plugging member 4 are both located on the same side of the first plug 2 means that, in the second direction, for any one of the first plugs 2, the first connecting member 3 and each first plugging member 4 are both located on the same side of it.

[0108] Similarly, when the number of the first plugs 2 is two, in the second direction, each third hole 13 is located between the two first plugs 2. At this time, that each third hole 13 is located on the same side of the first plug 2 in the second direction means that, in the second direction, for any one of the first plugs 2, each third hole 13 is located on the same side of it.

[0109] In addition, when the first hole 11 is a through hole and the first plugging member 4 is in clearance fit with the first hole 11, in the axial direction of the first hole 11, the blocking structure is located between the two first plugs 2, and the distance between at least one of the two first plugs 2 and the blocking structure is L4, where 0≤L4≤0.2 mm. In this way, the positions of the first plugging members 4 in the first hole 11 can be kept stable.

[0110] In other embodiments, the first plugging member 4 and the side wall of the first hole 11 may also be in sealed connection. At this time, the first plugging member 4 may be a sealing member such as a rubber sealing ring.

[0111] In other embodiments, the second hole 12 may also be a through hole penetrating the plate body 1. At this time, two second plugs 5 are needed to seal the second hole 12. At this time, in the second direction, each third hole 13 is located between the two second plugs 5. In this embodiment, that each third hole 13 is located on the same side of the second plug 5 in the second direction means that, in the second direction, for any one of the second plugs 5, each third hole 13 is located on the same side of it.

[0112] In other embodiments, the third hole 13 may also be a through hole penetrating the plate body 1. In this case, two third plugs 6 are required to close the third hole 13. At this time, in the first direction, the first hole 11 and the second hole 12 are located between two third plugs 6 (the two third plugs 6 are used to close the same third hole 13). In this embodiment, in the second direction, the first hole 11 and the second hole 12 being on the same side of the third plug 6 means that in the second direction, for any one of the third plugs 6, the first hole 11 and the second hole 12 are both on the same side of it.

[0113] In other embodiments, the first connecting member 3 may also be capable of contacting the side wall of the first hole 11. For example, the first connecting member 3 is a cylinder, the first hole 11 is a circular hole, and the axis of the first connecting member 3 is parallel but non-coaxial with the axis of the first hole 11. At this time, when the first connecting member 3 contacts the side wall of the first hole 11, the contact between the two may be a line contact.

[0114] An embodiment of the present invention further provides a lamination device, which includes the pressing plate 10 described in any one of the above (refer to Figure 4 ).

[0115] Among them, the lamination device may be a cold press. At this time, the pressing plate 10 is a cold pressing plate, which is used to cool the target product 30. The lamination device may be a hot press. At this time, the pressing plate 10 is a hot pressing plate, which is used to heat the target product 30.

[0116] In a scenario, the lamination device includes a plurality of pressing plates 10, and the pressing plates 10 are arranged at intervals along the vertical direction. At the same time, the lamination device further includes a corresponding area device, and the driving device is used to drive the pressing plates 10 to approach or move away from each other. When the pressing plates 10 approach each other, they can press the target product 20, and when the pressing plates 10 move away from each other, they can release the target product 20.

[0117] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
