In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0041] During the production process of carbon fiber paper, heat treatment is required to improve the strength and hardness of the carbon fiber paper.

[0042] In the related art, carbon fiber paper is connected to some parts by bonding, and then enters the furnace of a heat treatment device through a conveying device to achieve continuous operation of the carbon fiber paper.

The connection device includes a connection assembly, and the connection assembly includes a connection piece and at least two plates. The at least two plates are opposite to each other along a first direction, and a clamping space is formed between two adjacent plates. The plate is provided with connection holes, and the connection holes of two adjacent plates are correspondingly arranged and connected, and the connection piece is passed through the connection hole.

[0045] The content of the utility model will be described in detail below with reference to the accompanying drawings so that those skilled in the art can understand the content of the utility model more clearly and in detail.

Figure 2 A bottom view schematic diagram of a connecting device provided in an embodiment of the present application. Figure 3 A front view of a connecting device provided in an embodiment of the present application. Figure 4 for Figure 3 A magnified view of the part within the circular frame. Figure 5 Schematic diagram of a connecting member of a connecting device provided in an embodiment of the present application. Figure 1 -As shown in FIG. 5 , this embodiment provides a connection device 100 , including: at least one connection component 110 .

[0047] The connection assembly 110 includes a connection member 111 and at least two plates 112 . The at least two plates 112 are arranged opposite to each other along a first direction (P direction), and a clamping space is formed between two adjacent plates 112 .

[0048] The plates 112 each have a connecting hole 1121 . The connecting holes 1121 of two adjacent plates 112 correspond to each other and are connected to each other. The connecting holes 1121 are connected to the clamping space. The two adjacent plates 112 are detachably connected by a connecting piece 111 passing through the connecting hole 1121 .

[0049] According to the connection device 100 provided in this embodiment, at least two plates 112 are opposite in the first direction (direction P), and a clamping space is formed between adjacent plates 112. The material 200 is placed in the clamping space. When the connecting member 111 passes through the connecting hole 1121, the connecting member 111 pierces the material 200 to fix the material 200 in the clamping space. At the same time, the two adjacent plates 112 can press the material 200 along the first direction (direction P). In this way, the situation where the material 200 and the connection device 100 are disconnected can be reduced, the connection stability and movement continuity of the material 200 during the movement process are guaranteed, and the heat treatment efficiency is improved.

[0050] The specific structure of the connection device 100 and various possible implementations are described in detail below.

[0051] It should be noted that the material 200 in this embodiment can be carbon fiber paper, but is not limited to carbon fiber paper. The material 200 can be a carbon fiber paper roll or a carbon fiber paper after unwinding. The first direction (P direction) in this embodiment is the thickness direction of the plate body 112.

[0052] In this embodiment, the connection component 110 may be one, two or more, which is not limited in this section. Regardless of whether there are two or more connection components 110, the structure of the connection component 110 is the same, and this section only takes one connection component 110 as an example for description.

[0053] Exemplarily, the connection assembly 110 includes at least two plates 112. It can be understood that the number of the plates 112 in this embodiment can be two or more than two.

[0054] Combination Figure 1-Figure 4 As shown, when there are two plates 112, the two plates 112 are plate 112a and plate 112b, and plate 112a and plate 112b are arranged relatively along a first direction (P direction), and a clamping space is formed between plate 112a and plate 112b, and the clamping space can clamp the material 200.

[0055] It is easy to understand that the ends of the two materials 200 can be overlapped in sequence along the first direction (P direction), that is, the end of one of the two materials 200 covers the end of the other material 200, and the part is placed in the clamping space. The plate body 112a and the plate body 112b clamp the material 200 along the first direction (P direction).

[0056] The plate body 112a is provided with a connection hole 1121, which passes through opposite sides of the plate body 112a along the first direction (P direction), and the connection hole 1121 on the plate body 112a is connected to the clamping space; the plate body 112b is provided with a connection hole 1121, which passes through opposite sides of the plate body 112b along the first direction (P direction), and the connection hole 1121 on the plate body 112b is connected to the clamping space. The connection holes 1121 of the plate body 112a and the plate body 112b in this embodiment correspond one to one.

[0057] The connecting member 111 passes through the connecting holes 1121 of the plate body 112a and the plate body 112b in sequence along the first direction (direction P) to connect the plate body 112a and the plate body 112b. The connecting member 111 passes through the connecting hole 1121 and pierces the material 200, further fixing the material 200 between the plate body 112a and the plate body 112b. In this way, by connecting the ends of multiple materials 200 through the plate body 112 of the connecting assembly 110 and the connecting member 111, the feeding continuity of the heat treatment of the material 200 is achieved, and the efficiency of the heat treatment is improved.

[0058] After the material 200 is subjected to high-temperature carbonization treatment, the adhesive in the carbon fiber paper (material 200) loses more than 50% of its weight, the adhesive performance of the material 200 is greatly weakened, and the material 200 is prone to breakage, which affects the continuity of the heat treatment of the material 200.

[0059] After the material 200 in this embodiment is connected to the connecting device 100, the connecting device 100 can clamp the material 200 along the first direction (direction P) and form a certain pressure on the material 200, so that the material 200 and the conveyor belt or conveyor roller are kept in contact with each other, preventing the material 200 from being unable to move after breaking in the furnace. It can be understood that even if the material 200 breaks, the material 200 can still move. In this way, the material 200 can move stably and continuously during the heat treatment, thereby improving the heat treatment efficiency.

[0060] It can be understood that when there are multiple plates 112, the multiple plates 112 are arranged in sequence along the first direction (direction P), a clamping space is formed between two adjacent plates 112, and the connecting member 111 connects the multiple plates 112 along the first direction (direction P) through the connecting holes 1121 of the plates 112, and fixes the material 200 between the adjacent plates 112. Such a connecting device 100 can connect multiple materials 200 at the same time and perform heat treatment at the same time, thereby improving the heat treatment efficiency.

[0061] In some embodiments, the connector 111 extends along a first direction (direction P); along the extending direction of the connector 111 , a size of at least one end of the connector 111 gradually decreases.

[0062] The connecting member 111 in this embodiment can be a columnar member, for example, a columnar member with a circular cross section. The connecting member 111 extends along the first direction (direction P), and along the first direction (direction P), the radial size of one end or both ends of the connecting member 111 gradually decreases, and the end of the connecting member 111 forms a tapered structure. During the use of the connecting device 100, the tapered structure at the end of the connecting member 111 facilitates the connecting member 111 to pierce the material 200 along the first direction (direction P). The use and installation of the connecting device 100 is convenient, which saves the preparation time for heat treatment and improves the efficiency of heat treatment.

[0063] Possibly, the size of the first end of the connecting member 111 gradually decreases, and the second end of the connecting member 111 has a protrusion 1111; the protrusion 1111 protrudes from a side of the plate body 112 away from the clamping space along the first direction (direction P).

[0064] Combination Figure 3-Figure 5 As shown, the connecting member 111 in this embodiment extends along the first direction (direction P), the radial dimension of the first end of the connecting member 111 gradually decreases, the first end of the connecting member 111 forms a conical structure, and the first end of the connecting member 111 passes through the connecting hole 1121 of the plate body 112 along the first direction (direction P), and is convenient for piercing the material 200 located in the clamping space formed by the adjacent plate body 112, so as to fix the material 200 in the clamping space.

[0065] The second end of the connecting member 111 has a protrusion 1111, and the protrusion 1111 protrudes from the side of the plate body 112 away from the clamping space along the first direction (direction P). In this way, the setting of the protrusion 1111 can reduce the contact area between the plate body 112 and the conveying roller or conveyor belt, reduce the friction there, thereby preventing the material 200 from breaking due to excessive friction or uneven friction, improve the stability and continuity of the material 200 in the heat treatment feeding, and further improve the heat treatment efficiency.

[0066] It should be noted that the surface of the protrusion 1111 in this embodiment can be arc-shaped, circular or square, etc., and this part does not make any specific limitation.

[0067] Furthermore, the plate body 112 near the protrusion 1111 has a groove, which is located at one end of the connecting hole 1121 near the protrusion 1111, and the groove is connected to the connecting hole 1121; the protrusion 1111 is at least partially located in the groove.

[0068] The plate 112a near the protrusion 1111 has a groove, and the groove and the connecting hole 1121 are arranged one by one, the groove is recessed toward the clamping space along the first direction (P direction), and the groove is connected to the connecting hole 1121 along the first direction (P direction). The shapes of the groove and the protrusion 1111 on the connecting member 111 match each other, and the protrusion 1111 is at least partially located in the groove.

[0069] It is not difficult to understand that during the feeding process of the material 200, the protrusion 1111 is located in the groove, and the groove wall of the groove limits the movement of the connecting member 111 along the feeding direction of the material 200, preventing the connecting member 111 from detaching from the connecting hole 1121, so as to improve the stability of the connecting device 100 in clamping the material 200, ensure the stability and continuity of the feeding of the material 200, and then improve the heat treatment efficiency.

[0070] When the connecting device 100 and the material 200 move as a whole on the conveyor belt or conveyor roller, it is inevitable that they will jump along the first direction (direction P). In order to prevent the connection between the connecting member 111 and the plate body 112 from being disconnected, the fastener 113 can be provided to ensure the stability of the connection of the connecting device 100 of the material 200. Possibly, the connecting assembly 110 in this embodiment also includes a fastener 113, which is sleeved on at least one end of the connecting member 111 outside the clamping space; along the first direction (direction P), the plate surface of the plate body 112 facing away from the clamping space abuts against the fastener 113.

[0071] In combination with the aforementioned embodiments, when the dimensions of both ends of the connecting member 111 gradually decrease, that is, both ends of the connecting member 111 are conical structures, there are two fasteners 113 in this embodiment, and the two fasteners 113 are sleeved on the two ends of the same connecting member 111 located outside the clamping space. At the same time, each fastener 113 abuts against the plate surface of the plate body 112 facing away from the clamping space. In this way, the material 200 can be clamped between the clamping space formed by the two adjacent plate bodies 112 through the connection between the fastener 113 and the connecting member 111.

[0072] When the size of the first end of the connecting member 111 gradually decreases and the second end of the connecting member 111 is a protrusion 1111, the fastener 113 is sleeved on the first end of the connecting member 111, so that the material 200 can still be clamped between the clamping space formed by two adjacent plates 112.

[0073] Specifically, the fastener 113 has a threaded hole, the connector 111 has an external thread 1112, and the fastener 113 is connected to the connector 111 through the threaded hole and the external thread 1112. In this way, the fastener 113 and the connector 111 are connected by threads, which facilitates the installation and removal of the connection device 100.

[0074] In some embodiments, there are multiple connection holes 1121 , and the multiple connection holes 1121 are distributed in a matrix on the same plate body 112 .

[0075] It is not difficult to understand that the connecting parts 111 and the connecting holes 1121 are arranged in a one-to-one correspondence, and the multiple connecting holes 1121 are distributed in a matrix along the same plate body 112 to be respectively connected to different connecting parts 111. In this way, there are multiple connection positions between the connecting device 100 and the material 200, thereby improving the reliability of the connection of the connecting device 100 to the material 200, preventing the material 200 from being disconnected from the clamping space, improving the stability and continuity of the feeding of the material 200, and thus improving the heat treatment efficiency.

[0076] In some embodiments, there are multiple connection components 110, and the multiple connection components 110 are arranged in sequence along the second direction (Q direction), and the second direction (Q direction) intersects with the first direction (P direction).

[0077] During the feeding process of the material 200, the connecting component 110 can be arranged along the length direction or width direction of the material 200, and connected to the material 200 along the first direction (direction P). Since when the length or width of the material 200 is large, one connecting component 110 cannot meet the connection requirements. Therefore, the connecting device 100 in this embodiment includes a plurality of connecting components 110, and the plurality of connecting components 110 are sequentially arranged along the length direction or width direction of the material 200. In this way, through the connection of the plurality of connecting components 110, the material 200 is more stable during feeding, and the continuity, stability and efficiency of the heat treatment are improved.

[0078] It should be noted that the second direction (Q direction) in this embodiment can be the length direction of the material 200 or the width direction of the material 200. At this time, the second direction (Q direction) is perpendicular to the first direction (P direction).

[0079] Furthermore, there is a spacing between adjacent connection components 110 along the second direction (Q direction). It is not difficult to understand that, on the basis of the connection components 110 arranged at intervals meeting the connection requirements, reducing the number of connection components 110 can reduce the connection time between the connection components 110 and the material 200, thereby improving the heat treatment efficiency of the material 200.

[0080] The connection device 100 provided in this embodiment includes at least one connection assembly 110; the connection assembly 110 includes a connection member 111 and at least two plates 112, at least two plates 112 are arranged relatively along a first direction (direction P), and a clamping space is formed between two adjacent plates 112; the plates 112 each have a connection hole 1121, the connection holes 1121 of two adjacent plates 112 correspond to each other and are interconnected, the connection holes 1121 are connected to the clamping space, and the two adjacent plates 112 are detachably connected through the connection member 111 passing through the connection hole 1121. Through such a structural setting, the situation where the material 200 and the connection device 100 are disconnected is reduced, the connection stability and movement continuity of the material 200 during the movement process are guaranteed, and the heat treatment efficiency is improved.

[0081] In addition, this embodiment can also provide a heat treatment device, including a conveying roller and the connecting device 100 mentioned in any of the above embodiments, and the connecting device 100 is movably arranged through the conveying roller.

[0082] The heat treatment equipment provided in this embodiment can improve the heat treatment efficiency of the material 200 because it includes the connecting device 100 mentioned in any of the aforementioned embodiments.
