[0026] See also Figure 1 to Figure 8 In an embodiment of the present invention, a fully automatic vacuum forming production line includes: a base 1, a brush 19, a driving component, a guide mechanism and a deflection component, so that after the brush 19 performs an impurity erasing action, it can perform a lifting action, and in the process of downward movement, the brush 19 has a state of first accelerating and then instantaneous movement, and can shake off the impurities adhering to the brush 19 under the action of inertia, preventing the impurities from adhering to the brush 19 and falling back on the lower mold 5 when performing the next erasing action, thereby improving the effect of erasing impurities, as follows: The base 1 is provided with a bracket 2 and a lower mold 5, the bracket 2 is provided with a hydraulic cylinder 3, and the action end of the hydraulic cylinder 3 is connected with an upper mold 4 adapted to the lower mold 5; The brush 19 is disposed on the base 1, and the brush 19 can wipe away the dust on the lower mold 5; The driving assembly is mounted on the base 1, and the driving assembly is used to drive the brush 19 to move; The driving assembly comprises a side plate 7 mounted on the base 1, two sets of transmission wheels 9 are rotatably mounted on the side plate 7, a transmission belt 10 is sleeved between the two sets of transmission wheels 9, and a rotating shaft of one set of the transmission wheels 9 is connected to an output shaft of a driving device 8 mounted on the side plate 7; The driving assembly further comprises a guide member 13 disposed on the base 1, a follower member is disposed on the guide member 13, the follower member is connected to the transmission belt 10 via a fitting structure, the fitting structure comprises a sliding member 12 slidably mounted on the guide member 13, a connecting plate 15 is mounted on the sliding member 12, and the connecting plate 15 is provided with a fitting groove 1501 along its length direction; The interlocking structure further includes a connecting shaft 11 rotatably connected to the transmission belt 10 , and the connecting shaft 11 can roll in the interlocking groove 1501 ; The slide 12 forms the driven element.

[0027] After the blistering is completed, the driving device 8 is controlled to work. At this time, the output shaft of the driving device 8 can drive the transmission wheel 9 connected thereto to rotate, and the transmission belt 10 sleeved between the two transmission wheels 9 is activated, wherein the transmission belt 10 can be regarded as consisting of two circular segments and two straight segments, so that when the connecting shaft 11 follows the movement of the transmission belt 10, it can cooperate with the engaging groove 1501, and drive the sliding member 12 to reciprocate along the length direction of the guide member 13, thereby driving the brush 19 to reciprocate, and the impurities on the upper surface of the lower mold 5 are wiped off to avoid the presence of impurities affecting the subsequent blistering effect. In this embodiment, after the blistering is completed, the brush 19 only needs to move from one end of its stroke end to the other end.

[0028] Through the above arrangement, after the blistering is completed, the brush 19 can perform a horizontal movement to wipe off the impurities adhering to the lower mold 5, so as to prevent the impurities from adhering to the lower mold 5 and affecting the subsequent blistering effect.

[0029] It should be noted that, since the upper mold 4 is in a state where the blister surface is facing downward, the impurities that can adhere to it are very small and can be ignored.

[0030] See also Figure 7~Figure 8The guide mechanism connects the driving component and the brush 19, and the guide mechanism includes a guide component and an elastic component. The guide component cooperates with the elastic component to drive the brush 19 to perform a lifting action when the brush 19 moves to the end of the stroke; The guide assembly includes a pulley 18 connected to the elastic assembly and a guide plate 23 arranged on the base 1, and the guide plate 23 is provided with a guide groove, and the pulley 18 can roll in the guide groove; When the pulley 18 moves to the end of the guide groove, the elastic component can pull the pulley 18 to move vertically downward; The guide groove comprises a second horizontal groove 2303 provided on the guide plate 23, each end of the second horizontal groove 2303 is connected to a first horizontal groove 2302, an end of the first horizontal groove 2302 away from the second horizontal groove 2303 is provided with a vertical groove 2301 perpendicular to the first horizontal groove 2302, the vertical groove 2301 is connected to a third horizontal groove 2305 parallel to the first horizontal groove 2302, and an end of the third horizontal groove 2305 away from the vertical groove 2301 is connected to an end of the first horizontal groove 2302 away from the vertical groove 2301 through an inclined groove 2304; A deflection plate 25 is rotatably mounted at the connection between the inclined groove 2304 and the first horizontal groove 2302, and the deflection plate 25 can guide the pulley 18 to move from the second horizontal groove 2303 toward the inclined groove 2304; The elastic component includes a vertical plate 14 connected to the sliding member 12, a follower 16 is slidably mounted on the vertical plate 14, the follower 16 is rotationally connected to the pulley 18 and the brush 19, and a spring 17 is connected to the follower 16, and one end of the spring 17 away from the follower 16 is connected to the sliding member 12.

[0031] In the initial state, the pulley 18 is at one end of the first horizontal groove 2302 away from the second horizontal groove 2303, and the spring 17 is in a stretched state. As the sliding member 12 moves, the brush 19 will move horizontally, and the fluff on the brush 19 will wipe off the impurities adhering to the lower mold 5, that is, the pulley 18 will move toward the second horizontal groove 2303 along the length direction of the first horizontal groove 2302, and when the pulley 18 abuts against the deflection plate 25, the deflection plate 25 can be deflected, and when the pulley 18 moves into the second horizontal groove 2303, the deflection plate 25 can automatically reset under the action of gravity, and as the pulley 18 continues to move, the pulley 18 will abut against the deflection plate 25 on the other side, and at this time, the end of the deflection plate 25 away from its rotation center is in contact with the second horizontal groove 23 03, so that the pulley 18 can move along the deflection plate 25 to move into the inclined groove 2304, so that the brush 19 can move upward at an angle and separate from the lower mold 5, and at the same time the spring 17 is further stretched until the pulley 18 moves into the third horizontal groove 2305, the brush 19 will move horizontally, and when the pulley 18 moves to the end of the third horizontal groove 2305, the spring 17 will release its elastic potential energy, and pull the follower 16 and the brush 19 to move downward rapidly, and when the pulley 18 abuts against the lower side wall of the first horizontal groove 2302, the brush 19 stops moving instantly, so that impurities can be separated from the brush 19 under the action of inertia.

[0032] Through the above arrangement, after the brush 19 performs the impurity wiping action, it can perform a lifting action, and in the process of downward movement, the brush 19 has a state of first accelerating and then instantaneous movement, and can shake off the impurities adhering to the brush 19 under the action of inertia, preventing the impurities from adhering to the brush 19. When the next wiping action is performed, the impurities fall back on the lower mold 5, thereby improving the impurity wiping effect.

[0033] See also Figure 3~Figure 4 , Figure 7~Figure 8 The deflection assembly is connected to the rotating shaft of the brush 19. The deflection assembly can drive the brush 19 to reciprocate when the brush 19 moves to the end of the stroke. The deflection assembly includes a connecting rod 21 connected to the rotating shaft of the brush 19. The connecting rod 21 is located at the upper part of the rotating shaft of the brush 19 and is rotatably mounted with a convex shaft 22. The connecting rod 21 is located at the lower part of the rotating shaft of the brush 19 and is connected with a counterweight block 20. The deflection assembly also includes a guide structure arranged on the guide plate 23 and adapted to the convex shaft 22, the guide structure includes a first vertical plate 26 and a second vertical plate 27 installed on the guide plate 23, a serpentine channel 28 is formed between the first vertical plate 26 and the second vertical plate 27, and when the convex shaft 22 slides in the serpentine channel 28, it can drive the brush 19 to swing.

[0034] As the brush 19 accelerates downward, the convex shaft 22 will enter the serpentine channel 28 and, under the guidance of the serpentine channel 28, drive the connecting rod 21 to swing back and forth, thereby enabling the brush 19 to swing back and forth. At this time, on the one hand, the centrifugal force can be used to brush away the impurities adhering to the brush 19, and on the other hand, the mutual friction between the bristles on the brush 19 can be used to throw the impurities off.

[0035] The function of the counterweight 20 is to always keep the brush surface of the brush 19 facing downward.

[0036] Through the above arrangement, when the brush 19 moves downward, the convex shaft 22 can drive the brush 19 to swing rapidly under the guidance of the serpentine channel 28. On the one hand, it can use the centrifugal force to brush away the impurities adhering to the brush 19, and on the other hand, it can use the mutual friction between the bristles on the brush 19 to throw off the impurities, thereby further reducing the residual amount of impurities on the brush 19.

[0037] See also Figure 1 , Figure 3 An exhaust fan is also provided in the base 1, and the air inlet of the exhaust fan is connected to the cover plate 6 provided on the base 1, and the exhaust fan is electrically connected to two contact switches 24 symmetrically provided on the guide plate 23. When the brush 19 moves to the end of the stroke, the contact switch 24 can cooperate with the vertical plate 14 to make the contact switch 24 conductive.

[0038] When the brush 19 moves to the end of its stroke, the vertical plate 14 can abut against the contact switch 24, making the contact switch 24 conductive. At this time, the exhaust fan is activated, so that the air near the cover plate 6 can be drawn into the exhaust fan. At this time, the brush 19 is in a state of shaking off impurities, so that after the impurities are shaken off, they can be quickly sucked away to prevent impurities from spreading in the air and return to the lower mold 5, further improving the impurity removal effect.

[0039] As an embodiment of the present invention, a method for using the fully automatic blister forming production line is also proposed, comprising the following steps: Step 1: placing the sheet between the upper mold 4 and the lower mold 5, and heating the sheet with an external heating device to soften the sheet; Step 2: Control the hydraulic cylinder 3 to move the upper mold 4 toward the lower mold 5 until the two are in contact with each other, and then perform the blistering operation; Step 3: After the blister is completed, remove the blister and control the drive assembly; Step 4: When the driving component is in motion, the brush 19 is driven to move, and under the action of the deflection component and the guide mechanism, the brush 19 is deflected and vibrated, thereby shaking off the impurities adhering to the brush 19.
