The specific technical scheme is as follows:

[0006] A foam board trimming device comprises a workbench, a controller is installed on the workbench, a through cavity is opened from front to back through the workbench, an air pump is installed in the through cavity, two first positioning seats are respectively installed on the front and rear corresponding inner walls of the through cavity, two second positioning seats and two grooved plates are respectively installed on the front and rear corresponding upper surfaces of the workbench, the two grooved plates are arranged between the two second positioning seats, and the two grooved plates are respectively provided with accommodating grooves on opposite sides, the output end of the air pump is connected with a ventilation pipe, and the output end of the air pump is connected to the middle part of the ventilation pipe, the two ends of the ventilation pipe respectively pass through the first positioning seat and the second positioning seat, and extend into the grooved plates, the two grooved plates are respectively provided with air bags, and the two ends of the ventilation pipe are respectively connected with the two air bags;

[0007] Wherein, a foam plate is positioned between the two air bags.

[0008] In the above technical solution, three groups of drive systems are arranged on the workbench, and the three groups of drive systems are arranged along the XYZ axes respectively. A connecting seat is arranged on the drive system in the X-axis direction, and a stepper motor is installed on the rear side wall of the connecting seat. The output end of the stepper motor is connected to a rotating knife shaft.

[0009] In the above technical solution, a support base is provided on the driving system in the X-axis direction, and one end of a dust suction pipe is penetrated through the support base, and the one end of the dust suction pipe corresponds to the position of the rotating knife shaft. A processing box is provided on the left side wall of the workbench, and the other end of the dust suction pipe extends into the inner cavity of the processing box.

[0010] In the above technical solution, a fan is installed on the front side wall of the processing box, a first blocking net is installed in the horizontal direction of the inner cavity of the processing box, a second blocking net is installed on the inner side wall of the processing box, and the connection point between the fan and the processing box corresponds to the position of the second blocking net. A mounting plate is vertically installed on the top of the inner wall of the processing box, and a guide plate is installed on the bottom end of the mounting plate.

[0012] In the above technical solution, a water pump is provided on the side wall of the treatment box, and the water pump is connected to the lower part of the inner cavity of the treatment box.

[0015] Compared with the prior art, the foam board trimming device of the utility model has the following beneficial effects:

[0016] First, when cutting and trimming the foam board, the high-speed rotating rotary knife shaft contacts the light foam board for a moment, which will cause the foam board to be displaced during the cutting process due to the principle of action and reaction force, greatly interfering with the precise trimming of the slotted edge, and ultimately leading to a lower qualified rate of the finished foam board.

[0017] Second, in view of the material characteristics of the foam board, it is very easy to brittle fracture when it is squeezed by external force. The traditional method often uses a hard material positioning plate to position the foam board. However, when the hard positioning plate applies positioning pressure, it is very easy to cause the foam board to be crushed. The two sets of air bags provided by the utility model adopt an inflation and deflation mechanism, which can flexibly adjust the air bags according to actual needs, so that it can conveniently realize the positioning and de-positioning operations of the foam board. In addition, the air bag adopts a flexible air bag as a positioning element. Compared with the traditional hard material positioning plate, the flexible air bag can effectively buffer the pressure during the positioning process and avoid local stress concentration, thereby greatly reducing the risk of brittle fracture of the foam board in the positioning link, ensuring the reliability of the foam board trimming and positioning and the product yield rate;

[0018] 3. The utility model is aimed at the collection system of foam particles generated during the trimming process. The system uses the anti-static mixed liquid stored in the internal cavity of the processing box to spray and effectively remove the static electricity on the surface of the foam particles. On the one hand, the foam particles can be efficiently collected, and on the other hand, the anti-static treatment is completed simultaneously during the collection process. After this treatment, the subsequent centralized collection of foam particles becomes more convenient, effectively avoiding the problem of foam particles carrying static electricity and adsorbing on the inner cavity wall of the processing box, which makes it difficult to collect and clean, thereby improving the overall work efficiency and the convenience of cleaning and maintenance;

[0019] Fourth, after the anti-static mixed liquid in the treatment box of the utility model is used to perform anti-static treatment on the foam particles collected in the inner cavity of the treatment box through the water pump, the infusion tube, the spray seat, and the nozzle, the foam particles with the anti-static mixed liquid and the anti-static mixed liquid can be separated by means of the first blocking net and the second blocking net, so as to realize the repeated recycling of the anti-static mixed liquid, that is, the foam particles collected into the inner cavity of the treatment box at the dust suction pipe can be continuously subjected to continuous anti-static treatment, so as to ensure the high efficiency and continuity of the anti-static process, and effectively improve the resource utilization efficiency and system working efficiency;

[0020] In summary, the utility model effectively ensures the stability of the foam board during cutting and trimming, improves the trimming accuracy and the qualified rate of finished products; secondly, it uses the inflation and deflation mechanism and the flexible airbag for positioning, successfully avoiding the brittle fracture of the foam board due to external force squeezing, and effectively guarantees the positioning reliability and product yield; thirdly, for the foam particles generated by trimming, an efficient collection system is constructed, which can simultaneously complete the destaticization treatment during the collection process, effectively avoiding the collection and cleaning problems caused by electrostatic adsorption, and greatly improving work efficiency and the convenience of cleaning and maintenance; finally, the repeated recycling of the destaticization mixed liquid is realized, ensuring the efficient and continuous destaticization process, and further improving the resource utilization efficiency and system work performance.
