Description

Technical Field

[0001] The utility model belongs to the technical field of carbon fiber processing, in particular to a heat-conducting carbon fiber plate pressing device with adjustable pressure. Background Art

[0002] Thermally conductive carbon fiber is a high thermal conductivity carbon fiber material developed for thermal engineering design. The thermal conductivity of this carbon fiber in the fiber direction can exceed that of copper, up to 700W / mk. It also has good mechanical properties, electrical conductivity, and excellent thermal conductivity and radiation heat dissipation capabilities. The fibrous high thermal conductivity carbon powder made of this carbon fiber is fibrous in shape and can be designed with a thermal orientation. This is the biggest difference and advantage from previous carbon powders and other thermally conductive materials. It can be used to fill polymer composites, develop heat dissipation materials for electronic appliances, and solve heat dissipation problems of high-density integrated electronic components and LEDs.

[0003] At present, pressing is basically required in the processing of carbon fiber boards. The conventional pressing process directly provides pressing force and directly presses the carbon fiber boards. Due to the large pressing force, the carbon fiber boards directly receive large force, and some internal areas are not pressed properly. Since the pressing of the surrounding buckets is stable, the areas that are not pressed properly cannot be pressed and changed later. A step-by-step pressing device is needed to perform step-by-step pressing to avoid the above situation. In addition, the pressure needs to be adjusted as needed for different carbon fiber board requirements. Utility Model Content

[0029] Example 1

[0030] See attached Figure 1-2The present embodiment is a heat-conducting carbon fiber plate pressing device with adjustable pressure, comprising a base frame 100 and a pressing assembly 200, wherein the base frame 100 is provided with a plurality of bottom rollers arranged in parallel, the pressing assembly 200 comprises a first pressing module group 210, a second pressing module group 220 and a third pressing module group 230, the first pressing module group 210, the second pressing module group 220 and the third pressing module group 230 are all provided with pressing rollers 240 corresponding to the bottom rollers, the pressing rollers 240 and the bottom rollers press the carbon fiber plate together, the pressing assembly 200 is provided with an adjusting assembly 250, and the adjusting assembly 250 is used to adjust the pressing assembly 200 0 pressure on the carbon fiber board. The structure of this design uses a pressing assembly 200 to press the carbon fiber board, so that the carbon fiber board molding is more stable. Three groups of modules are provided, namely a first pressing module 210, a second pressing module 220 and a third pressing module 230. Pressing is performed in sequence, so that the pressing process gradually increases the pressing force, making the pressing smoother and better. For carbon fiber boards of different specifications or models, different degrees of pressing operations are performed by adjusting the pressure. It should be noted that a driving motor is provided on the base frame 100 to drive the bottom roller to roll. This is a conventional solution in the prior art and will not be described here.

[0031] The first pressing module 210, the second pressing module 220 and the third pressing module 230 of the present embodiment all include a mounting frame 211, a square shaft rod 212, a connecting rod 213, a pressing plate 214 and a top frame 215. The pressing roller 240 is installed on the mounting frame 211. One end of the connecting rod 213 is connected to the mounting frame 211, and the other end passes through the top frame 215 and is provided with a limit 216. The connecting rod 213 is sleeved with a pressing plate 214. One end of the square shaft rod 212 is connected to the pressing plate 214, and the other end passes through the top frame 215 and extends out. The connecting rod 213 on the first pressing module 210 is sleeved with a spring 1 217, the connecting rod 213 on the second pressing module 220 is sleeved with a spring 221, and the connecting rod 213 on the third pressing module 230 is sleeved with a spring 224. There is spring three 231, and the adjustment component 250 is used to adjust the compression amount of the pressing plate 214 pressing the spring one 217, the spring two 221 and the spring three 231. In this design structure, when the pressing operation is carried out, the pressing roller cooperates with the bottom roller to press the carbon fiber plate. As the rotation of the bottom roller drives the carbon fiber plate to move, the carbon fiber plate is operated continuously and stably during the entire pressing process. During the pressing process, the spring one 217, the spring two 221 and the spring three 231 are all in a compressed state, ensuring the continuous stability of the pressing roller on the carbon fiber plate. It should be noted that when the carbon fiber plate passes under the pressing roller 240, the pressing roller 240 will be lifted, that is, the corresponding spring one 217, the spring two 221 and the spring three 231 are further compressed.

[0032] The adjustment assembly 250 of this embodiment includes an adjustment motor 251, an adjustment shaft 252 and a slider 253. The adjustment shaft 252 is a threaded shaft. The adjustment motor 251 drives the slider 253 to slide through the adjustment shaft 252. The slider 253 contacts the square shaft rod 212 in the first pressing module 210, the second pressing module 220 and the third pressing module 230.

[0033] The top of the square shaft rod 212 of this embodiment is a round head structure, the bottoms of the square shaft rods 212 of the first pressing module 210, the second pressing module 220 and the third pressing module 230 are in the same horizontal plane and the round head structures on the top of the square shaft rod 212 are tangent to the upper inclined surface of the slider 253.

[0034] In this embodiment, the elastic strengths of the spring 1 217 , the spring 221 , and the spring 3 231 increase in sequence, and the carbon fiber plate passes under the spring 1 217 , the spring 221 , and the spring 3 231 in sequence.

[0035] In the above structure, when pressure is adjusted, the slider 253 is driven to move by adjusting the motor 251, thereby driving the square shaft 212 to move up and down, changing the initial compression amount of spring 1 217, spring 221 and spring 3 231, and then changing the initial pressure of the pressing roller 240, thereby achieving the process of adjusting the pressure.

[0036] Working principle: First, place the carbon fiber plate to be pressed on the bottom roller of the base frame 100, and drive the bottom roller to roll through the driving motor on the base frame 100, so as to drive the carbon fiber plate to move to the bottom of the pressing roller 240 and be pressed by the pressing roller 240. As the bottom roller continues to work, the entire carbon fiber plate is finally completely pressed. During adjustment, the adjustment shaft 252 is driven to move by the adjusting motor 251, and then the square shaft rod 212 is driven to move up and down, so as to change the pressure of the pressing plate 214 on the spring, and change the overall deformation of spring one 217, spring two 221 and spring three 231.

[0037] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
