Within the flipping stroke range of the movable plate 4215, when the movable plate 4215 is in the initial position, the bottom of the movable plate 4215 abuts against the top surface of the supporting plate 4213, thereby blocking the refrigerant ball 4214 carried on the top of the supporting plate 4213. When the movable plate 4215 is in the terminal position, the maximum distance between the bottom of the movable plate 4215 and the top surface of the supporting plate 4213 is not less than the diameter of the refrigerant ball 4214 and not greater than the refrigerant ball 4214 is 1.5 times the diameter of the movable plate 4215 to ensure that when the movable plate 4215 is at the end position within the flipping stroke range, the refrigerant ball 4214 can pass through the lower side of the movable plate 4215 smoothly through the guide groove 42131, and roll down along the guide groove 42131 to the baffle 4212 connected to the guide groove 42131, so that the user can adjust the flipping frequency of the movable plate 4215 by controlling the second motor to adjust the number of refrigerant balls 4214 falling on the baffle 4212 currently connected to the guide groove 42131, and finally achieve the flipping frequency of the movable plate 4215. The purpose of this invention is to adjust the counterweight of the track shoe 4201 on the lower side of the bearing plate 4213; secondly, during the operation of the traction track 4, the first refrigeration device injects its condensing agent into the guide hose through the input end of the guide hose, so that the refrigerant circulates along the guide hose and finally flows back to the first refrigeration device through the output end of the guide hose, thereby cooling the bearing plate 4213, thereby achieving the purpose of cooling the refrigerant ball 4214 located on the bearing plate 4213, so that after the refrigerant ball 4214 rolls onto the track shoe 4201, it can cool the track shoe 4201 through heat transfer. The purpose of cooling the air around the belt plate 4201 and the track plate 4201 is to enhance the cooling effect of the equipment on the foam plate; secondly, with the transmission of the annular chain structure, when the track plate 4201 is transmitted to the upper side of the bearing plate 4213, with the angular deflection of the bearing plate 4213, the refrigerant ball 4214 carried by the track plate 4201 rolls down to the top of the bearing plate 4213 again along the guidance of the baffle plate 4212 and is intercepted by the movable plate 4215, thereby increasing the heat exchange efficiency of the coolant circulating in the guide hose to the refrigerant ball 4214.

[0035] Further, if Figure 2 As shown, the device further comprises: a distance measuring sensor module 5, which is arranged at the output end of the extruder 2 and is used to detect the output length of the foamed board.

[0036] Further, if Figure 2 , Fig.10As shown, the distance measuring sensor module 5 includes: a bearing bracket 51, which is fixedly arranged at the output end of the extruder 2; a transmission roller 52, which is arranged on the bearing bracket 51, and both ends of the transmission roller 52 are rotatably connected to the bearing bracket 51, and the transmission roller 52 is arranged along the width direction of the foamed board. In the process of the extruder 2 outputting the foamed board, the circumferential side wall surface of the transmission roller 52 is in contact with the outer surface of the foamed board; an encoder 53, which is fixedly arranged on the bearing bracket 51, and the detection end of the encoder 53 is connected to the transmission roller 52, and the encoder 53 is electrically connected to an external control device for detecting the number of rotations of the transmission roller 52.

[0037] During the process of extruding the foam board through the output end of the extruder 2, the outer surface of the foam board contacts the circumferential side wall surface of the drive roller 52, thereby driving the drive roller 52 to rotate. The encoder 53 detects the number of rotations of the drive roller 52 per unit time in real time, and transmits the detection data to an external control device, so that the control device can obtain the extrusion speed of the foam board based on the detection data of the encoder 53 and data such as the outer diameter of the drive roller 52, so that the user can adjust the transmission speed of the annular chain structure and the transmission speed of the conveyor belt of the belt conveyor device 3 according to the extrusion speed of the foam board.

[0038] Further, if Figure 2 As shown, the device further includes: a second refrigeration device 6, which is fixedly arranged inside the assembly shell 1, and the position of the second refrigeration device 6 matches the position of the belt conveyor device 3, and is used to cool the conveyor belt of the belt conveyor device 3.

[0039] During the operation of the equipment, the second refrigeration device 6 performs a cooling process on the conveyor belt of the belt conveyor device 3 .

[0040] Above, refer to Figure 1 to Figure 10 The foaming board extrusion equipment according to the embodiment of the present invention is described, which has the following beneficial effects: 1. The equipment utilizes a belt conveyor 3 and a traction crawler 4 to pull the foamed board, and ensures the traction force of the belt conveyor 3 and the traction crawler 4 on the foamed board by increasing the contact area between the foamed board and the traction device. At the same time, the equipment improves the problem of local deformation of the foamed board and the formation of pull marks on the surface of the foamed board caused by excessive local pressure during the traction of the foamed board by the belt conveyor 3 and the traction crawler 4, thereby solving the defects existing in the prior art.

[0041] 2. The equipment arranges a plurality of refrigerant balls 4214 movably inside the assembly cavity 4203. During the transmission process of the track shoe 4201, the refrigerant balls 4214 are quantitatively dropped onto the baffle 4212 on the track shoe 4201 through the movable plate 4215, so as to adjust the counterweight of the track shoe 4201 itself, thereby adjusting the traction force of the traction track 4 and the belt conveyor 3 on the foamed board.

[0042] 3. The device movably sets a plurality of refrigerant balls 4214 inside the assembly cavity 4203. During the transmission of the track plate 4201, the movable plate 4215 is controlled to quantitatively drop the refrigerant balls 4214 onto the track plate 4201 located on the lower side of the bearing plate 4213. The refrigerant balls 4214 are then transferred back to the bearing plate 4213 by the transmission of the track plate 4201, so that the refrigerant balls 4214 can be cooled by the coolant circulating in the guide hose arranged on the bearing plate 4213, thereby achieving the purpose of absorbing the heat of the track plate 4201 by the circulation of the refrigerant balls 4214, and further achieving the effect of cooling the foamed plate by heat transfer.
