[0014] The following will specifically describe the content of the present utility model in conjunction with the accompanying drawings and embodiments.

[0015] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the present utility model provides a punching device for EPS foam processing, including a bottom plate 1, a vertical plate 2 is fixed on the top of the bottom plate 1, a rotating cylinder 3 is rotatably connected through the vertical plate 2, bearing shells 4 are arranged around the rotating cylinder 3, and a fixed rod 41 is fixed between the bearing shell 4 and the rotating cylinder 3; two symmetrically distributed bracing plates 42 are arranged on the side of the bearing shell 4 away from the rotating cylinder 3, and two first electric telescopic rods 45 are arranged on the bearing shell 4, and the two first electric telescopic rods 45 are respectively used to drive the two bracing plates 42 to approach each other; a support frame 7 is fixed on the bottom plate 1 on one side of the rotating cylinder 3, an automatic telescopic rod 71 is arranged inside the support frame 7, a moving plate 72 is fixed at the telescopic end of the automatic telescopic rod 71, a mounting plate 73 is fixed on the moving plate 72, and an electric heating head 74 corresponding to the bearing shell 4 on one side of the rotating cylinder 3 is fixed on the mounting plate 73.

[0016] As Figure 1 , Figure 3 and Figure 4As shown in the figure, an opening is formed on the side of the bearing housing 4 away from the rotating cylinder 3. A connecting plate 5 flush with the side of the bearing housing 4 away from the rotating cylinder 3 is placed inside the opening. The connecting plate 5 is located between two abutting plates 42, and a group of through holes 52 are formed on the connecting plate 5. Two symmetrically distributed fixing bars 48 are fixed on the side of the bearing housing 4 away from the rotating cylinder 3. A bolt 51 is threadedly connected to the connecting plate 5, and a screw hole adapted to the bolt 51 is formed on the fixing bar 48. After the connecting plate 5 can be placed in the opening on the bearing housing 4, the fixing bar 48 can hold the connecting plate 5, and then the bolt 51 is used to fix the connecting plate 5 and the fixing bar 48 together. When the EPS foam molding is placed on the connecting plate 5, the part of the EPS foam molding that needs to be punched can be made to correspond to the through holes 52, so that when the heating head 74 punches the EPS foam molding, the heating head 74 can directly pass through the through holes 52 after passing through the EPS foam molding, and the heating head 74 will not contact the connecting plate 5, ensuring that the heating head 74 can smoothly punch the EPS foam molding. When punching different EPS foam moldings, different connecting plates 5 can be replaced according to the position of the hole positions opened on the EPS foam molding, so that the through holes 52 on different connecting plates 5 correspond to the positions where the hole positions need to be opened on the EPS foam molding. The number of the bearing housings 4 is four. Taking the bearing housing 4 Figure 1 above the rotating cylinder 3 as an example, the two abutting plates 42 on this bearing housing 4 are symmetrically distributed left and right.

[0017] As Figure 1 , Figure 3 and Figure 4 shown in the figure, two symmetrically distributed strip-shaped openings 43 are formed on the side of the bearing housing 4 away from the rotating cylinder 3. Slide plates 44 are fixed on the abutting plates 42, and the two slide plates 44 respectively pass through the two strip-shaped openings 43 and are slidably connected to the inner sides of the strip-shaped openings 43. Two first electric telescopic rods 45 are respectively fixed inside the bearing housing 4, and the telescopic ends of the two first electric telescopic rods 45 are respectively connected to the two slide plates 44. Two symmetrically distributed slideways 47 are formed on the side of the bearing housing 4 away from the rotating cylinder 3, and the two abutting plates 42 are respectively slidably connected to the two slideways 47 through sliders. The two fixing bars 48 are both located between the two first electric telescopic rods 45 inside the bearing housing 4, and the telescopic ends of the two first electric telescopic rods 45 face in opposite directions, which will not affect the normal movement of the telescopic ends of the first electric telescopic rods 45 to drive the abutting plates 42 through the slide plates 44. Taking the bearing housing 4 Figure 1 above the rotating cylinder 3 as an example, the two strip-shaped openings 43 are symmetrically distributed front and back, and the two slideways 47 are also symmetrically distributed front and back. The two strip-shaped openings 43 are both located between the two slideways 47 (taking Figure 1In the orientation shown); when the first electric telescopic rod 45 is activated, the telescopic end of the first electric telescopic rod 45 can drive the abutting plate 42 to move through the sliding plate 44, causing the two abutting plates 42 to approach each other. Moreover, the mutual cooperation between the slideway 47 and the slider on the abutting plate 42 can make the abutting plate 42 move more stably;

[0018] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a bearing plate 6 is fixed on one side of the bearing shell 4, and a second electric telescopic rod 61 is fixed on the bearing plate 6. The telescopic end of the second electric telescopic rod 61 is fixed with a positioning plate 62 that can move towards the space between the two abutting plates 42. After activating the second electric telescopic rod 61, the telescopic end of the second electric telescopic rod 61 can drive the positioning plate 62 to move towards the space between the two abutting plates 42. So, after adjusting the position of the positioning plate 62 according to EPS foam molding parts of different sizes, when the EPS foam molding part is placed on the bearing shell 4, it first contacts the positioning plate 62, and then the two abutting plates 42 approach each other to clamp and fix the EPS foam molding part, so that the staff can quickly place and fix the EPS foam molding part, and it is also convenient for the subsequent heating head 74 to accurately correspond to the parts that need to be drilled on the EPS foam molding part.

[0019] As Figure 1 , Figure 2 and Figure 4 shown, a cross beam 31 is fixed inside the rotating cylinder 3, and a storage battery 32 is embedded in the cross beam 31; a reinforcing plate 33 is sleeved on the rotating cylinder 3 in a rotatable connection manner, and a support plate 34 connected to the bottom plate 1 is fixed at the bottom of the reinforcing plate 33. The bearing shell 4 is located between the vertical plate 2 and the reinforcing plate 33; rubber pads 46 are fixed on the mutually approaching surfaces of the two abutting plates 42. The storage battery 32 can supply power to the first electric telescopic rod 45 and the second electric telescopic rod 61; the cooperation between the reinforcing plate 33 and the support plate 34 can increase the stability of the rotating cylinder 3. And a fixed block is fixed on the vertical plate 2, and a driving motor is installed on the fixed block. The rotating shaft of the driving motor is fixed to the end of the rotating cylinder 3 (the fixed block and the driving motor are not shown in the figure). After starting the driving motor, the rotating cylinder 3 can be rotated to change the position of a group of bearing shells 4 on the rotating cylinder 3; the rubber pads 46 can increase the friction between the abutting plates 42 and the EPS foam molding part, improving the fixing effect of the abutting plates 42 on the EPS foam molding part.

[0020] As Figure 1 and Figure 5As shown, a conveying unit 9 is fixed on the top of the bottom plate 1. The bottom of the support frame 7 is fixed on the conveying surface of the conveying unit 9. A motor 8 is fixed at the bottom inside the support frame 7. A lead screw 81 is fixed on the rotating shaft of the motor 8. A lifting block 82 is threadedly connected to the lead screw 81. An automatic telescopic rod 71 is fixed on the lifting block 82. The lifting block 82 is slidably connected inside the support frame 7. The conveying unit 9 includes a frame body, a driving roller, a driven roller, a control motor and a conveyor belt. The frame body is fixed on the bottom plate 1. The driving roller and the driven roller are rotatably connected inside the frame body. The control motor is installed on the frame body and its rotating shaft is fixed to one end of the driving roller. The driving roller and the driven roller are connected by the conveyor belt. The bottom of the support frame 7 is fixed on the conveyor belt. After starting the control motor, the conveyor belt can run, and the conveyor belt can drive the support frame 7 to move forward or backward (in the orientation shown in Figure 1 ), changing the position of the heating head 74 so that the heating head 74 can better correspond to the part of the EPS foam molding to be drilled; the motor 8 is a servo motor (the control motor on the conveying unit 9 is also a servo motor). After starting the motor 8 to rotate the lead screw 81, the lifting block 82 can move up or down, changing the height of the heating head 74; multiple heating heads 74 can be arranged on the mounting plate 73 according to actual conditions, so that when drilling the EPS foam molding, all the holes on the EPS foam molding can be processed at one time; the number of the automatic telescopic rods 71 is at least two, so as to better drive the moving plate 72 to move.

[0021] As Figure 1 shown, a set of grooves are formed on the top of the bottom plate 1. A rotating rod 11 with the top located above the bottom plate 1 is rotatably connected in the grooves. The rotating rod 11 is located between the vertical plate 2 and the reinforcing plate 33. An external collection box can be placed on the bottom plate 1, and the rotating rod 11 can support the external collection box. After the EPS foam molding is drilled and moved below the rotating cylinder 3, when the EPS foam molding drops downward, it can directly enter the external collection box for collection. When the subsequent staff drags the external collection box to move, the rotating rod 11 will rotate accordingly to assist the movement of the external collection box.

[0022] During use, after placing the EPS foam molding (foam board or foam box) on the bearing shell 4 directly above the rotating cylinder 3, start the two first electric telescopic rods 45 to make the two pressing plates 42 approach each other to clamp the EPS foam molding, thus completing the fixation of the EPS foam molding; then start the drive motor to rotate the rotating cylinder 3 counterclockwise by 90°, so that the bearing shell 4 with the EPS foam molding fixed corresponds to the heating head 74, and then start the automatic telescopic rod 71 to drive the moving plate 72 through the mounting plate 73 to drive the heating head 74 to move towards the EPS foam molding. When the heating head 74 contacts the EPS foam molding, the punching operation on the EPS foam molding can be carried out; when the EPS foam molding is undergoing the punching operation, the EPS foam molding to be punched can be placed on the bearing shell 4 that is directly above the rotating cylinder 3 at this time, and repeat the above operations to complete the fixation of the EPS foam molding. After the previous EPS foam molding is punched, the heating head 74 resets, then continue to rotate the rotating cylinder 3 to make the EPS foam molding to be punched correspond to the heating head 74, and the punched EPS foam molding is located directly below the rotating cylinder 3; when the heating head 74 continues to carry out the punching operation on an EPS foam molding, the staff can continue to fix other EPS foam moldings according to the above operations. At the same time, after the punched EPS foam molding is located directly below the rotating cylinder 3, the two pressing plates 42 used to fix the EPS foam molding can be separated from each other to make the EPS foam molding fall directly downward, thus completing the blanking of the EPS foam molding.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
