The separation mechanism includes a fixed frame fixedly connected to the frame and two positioning pins. The fixed frame is provided with a slider that can move along a first direction, and the slider is provided with a guide rod slidably connected to the upper heating plate and the lower heating plate. The upper heating plate and the lower heating plate are both movably connected to the positioning pins through a fixed plate provided with an inclined groove. The guide rod driven by the slider drives the inclined groove to move relative to the positioning pin to drive the upper heating plate and the lower heating plate to move closer and farther along the extension direction of the guide rod.

[0006] Preferably, the positioning pins are each provided with a pulley located in the inclined slot and capable of moving along the extending direction of the inclined slot, and the inclined slot comprises:

[0035] The utility model aims to provide a separation mechanism suitable for a blister machine, which can prevent the PVC material from being damaged by excessive heating when the machine is stopped.

[0036] It should be noted that, in this embodiment, the X direction in the drawings is defined as the first direction, the Y direction is defined as the second direction, and the first direction and the second direction form an angle with each other.

[0037] See also Figures 1 to 4 To achieve the above-mentioned purpose, the utility model provides a separation mechanism suitable for a blister machine, which is installed on a frame of the blister machine. The separation mechanism includes a fixing frame 100 fixedly connected to the frame and two positioning pins 200. The fixing frame 100 is provided with a slider 300 that can move along a first direction, and the slider 300 is provided with a guide rod 310 slidably connected to an upper heating plate 400 and a lower heating plate 500. The upper heating plate 400 and the lower heating plate 500 are both movably connected to the positioning pins 200 through a fixing plate 600 provided with an inclined groove 610. The guide rod 310 driven by the slider 300 drives the inclined groove 610 to move relative to the positioning pin 200, so as to drive the upper heating plate 400 and the lower heating plate 500 to approach and move away from each other along the extending direction of the guide rod 310.

[0038] It should be noted that the extension direction of the guide rod 310 is at an angle to the first direction, and the guide rod 310 preferably extends along the second direction. The guide rod 310 in this embodiment includes two straight rods parallel to each other, and the guide rod 310 passes through the slider 300 along its own extension direction. It is also possible to set internal threads at both ends of the slider 300 according to actual needs. The external threads set at the end of the guide rod 310 cooperate with the internal threads on the slider 300 to achieve the fixation of the guide rod 310 relative to the slider 300. Preferably, the two ends of the inclined groove 610 are respectively the first end and the second end, to facilitate the understanding of this solution.

[0039] The fixing frame 100 and the two positioning pins 200 are both fixedly arranged. When the blister machine stops, the slider 300 moves relative to the fixing frame 100, driving the upper heating plate 400 and the lower heating plate 500 connected to the guide rod 310 to move along the first direction. At the same time, the fixing plate 600 connected to the upper heating plate 400 and the lower heating plate 500 is connected through the inclined groove 610 and the positioning pin 200. Under the restriction and guiding effect of the inclined groove 610 (the first end of the inclined groove 610 contacts the positioning pin 200 and the second end of the inclined groove 610 contacts the positioning pin 200), the upper heating plate 400 and the lower heating plate 500 are moved. 00 are away from each other along the extension direction of the guide rod 310. When the blister machine is running, the upper heating plate 400 and the lower heating plate 500 connected to the guide rod 310 are driven by the slider 300 to move along the first direction, and under the restriction and guiding action of the inclined groove 610 (the second end of the inclined groove 610 is in contact with the positioning pin 200 and the first end of the inclined groove 610 is in contact with the positioning pin 200), the upper heating plate 400 and the lower heating plate 500 are close to each other along the extension direction of the guide rod 310 for heating the PVC material. Such an arrangement can avoid the PVC material being damaged by overheating when the machine is stopped.

[0040] Preferably, the positioning pins 200 are each provided with a pulley located in the inclined groove 610 and capable of moving along the extension direction of the inclined groove 610, the inclined groove 610 includes an inclined portion 612 and at least two horizontal portions 611, at least two horizontal portions 611 extend along a first direction, and adjacent horizontal portions 611 are arranged at different heights; the inclined portion 612 connects two adjacent horizontal portions 611 so that the pulley can move to all horizontal portions 611.

[0041] In this embodiment, the inclined slot 610 preferably includes two horizontal portions 611 and an inclined portion 612 connected to the two horizontal portions 611. The inclined slot 610 can move relative to the positioning pin 200 at a fixed position. When the horizontal portion 611 at the first end of the inclined slot 610 contacts the positioning pin 200, the distance between the horizontal portions 611 at the second end of the inclined slot 610 is smaller than the distance between the two positioning pins 200. When the horizontal portion 611 at the second end of the inclined slot 610 contacts the positioning pin 200, the distance between the horizontal portions 611 at the second end of the inclined slot 610 is smaller than the distance between the two positioning pins 200. The distance between the horizontal portions 611 at the first end of the groove 610 is greater than the distance between the two positioning pins 200. The upper heating plate 400 and the lower heating plate 500 are both movably connected to the positioning pins 200 via a fixed plate 600 having an inclined groove 610. The upper heating plate 400 and the lower heating plate 500 are fixed relative to the corresponding inclined groove 610. The distance between the two horizontal portions 611 located at the first end and / or the second end is changed, so that the distance between the upper heating plate 400 and the lower heating plate 500 is increased or decreased.

[0042] Among them, the two horizontal parts 611 extend along the first direction, and the adjacent horizontal parts 611 are set at different heights, that is, the corresponding positions of the two horizontal parts 611 in the extension direction of the guide rod 310 are different, so as to realize the movement of the upper heating plate 400 and the lower heating plate 500 along the second direction. Preferably, the extension direction of the guide rod 310 is perpendicular to the extension direction of the cross bar 130, that is, the first direction and the second direction in this embodiment are preferably perpendicular to each other. In addition, the specific angle between the first direction and the second direction can be adjusted according to actual conditions as long as the above-mentioned purpose can be achieved.

[0043] It should be noted that, in this embodiment, there can be multiple horizontal portions 611, and the multiple horizontal portions 611 are interconnected through the inclined portion 612, and all the horizontal portions 611 are arranged at different heights, so that the distance between the upper heating plate 400 and the lower heating plate 500 can be adjusted in various ways as needed. No specific limitation is made here, as long as the above purpose can be achieved.

[0044] Preferably, the fixing frame 100 also includes a first fixing block 110 and a second fixing block 120 connected by a cross bar 130, the cross bar 130 extends along a first direction and passes through the slider 300, a cylinder 140 is provided between the slider 300 and the second fixing block 120, so that the slider 300 driven by the cylinder 140 approaches and moves away from the second fixing block 120 along the extension direction of the cross bar 130, and a U-shaped groove 320 capable of accommodating the cylinder 140 is provided on the slider 300, the cylinder 140 includes a cylinder body and a piston rod capable of relative movement, the cylinder body is connected to the second fixing block 120, and the piston rod is connected to the bottom of the U-shaped groove 320.

[0045] It can be understood that the fixing frame 100 also includes a cross bar 130, a first fixing block 110 and a second fixing block 120, the cross bar 130 extends along the first direction, the fixed first fixing block 110 and the second fixing block 120 are connected by two cross bars 130 arranged parallel to each other, the slider 300 is located between the first fixing block 110 and the second fixing block 120, and is provided with a first through hole for the cross bar 130 to pass through, so that the slider 300 can slide along the first direction, and a cylinder 140 is provided between the slider 300 and the second fixing block 120, which is used to drive the slider 300 to approach and move away from the second fixing block 120 along the extension direction of the cross bar 130.

[0046] Among them, the slider 300 is preferably provided with a U-shaped groove 320 including two sides and a bottom, and the U-shaped groove 320 can accommodate the cylinder 140 that is not driven by gas, and the cylinder 140 includes a piston rod connected to the bottom of the U-shaped groove 320 and a cylinder body connected to the second fixed block 120 on the side close to the U-shaped groove 320. The distance between the second fixed block 120 and the slider 300 is changed by the relative movement of the cylinder body and the piston rod, and then the distance between the upper heating plate 400 and the lower heating plate 500 is changed by the relative position change of the inclined groove 610 and the positioning pin 200.

[0047] In order to avoid collision between the positioning pin 200 and the two ends of the inclined slot 610 in the first direction, it is preferred that the length of the inclined slot 610 in the first direction is greater than the length of the piston rod in the first direction. Moreover, the movement of the inclined slot 610 driven by the piston rod relative to the positioning pin 200 is between the two ends of the inclined slot 610 in the first direction. The size of the gap between the limit position of the positioning pin 200 and the end of the inclined slot 610 can be adjusted according to actual conditions, as long as the above purpose can be achieved.

[0049] In this embodiment, linear bearings 410 are provided between the upper heating plate 400 and the guide rod 310, as well as between the lower heating plate 500 and the guide rod 310, so as to reduce or even avoid wear between the upper heating plate 400 and the guide rod 310, as well as between the lower heating plate 500 and the guide rod 310 during relative movement, and the linear bearings 410 are fixed to the upper surface of the upper heating plate 400 and the lower surface of the lower heating plate 500 through a mounting seat 420, and the fixing parts passing through the mounting seat 420 are preferably bolts.

[0050] Preferably, the horizontal parts 611 are each provided with a sensor connected to the central control system, so that when the pulley moves to a preset position, a corresponding sensor located at the bottom of the pulley sends a signal to the central control system to control the power source connected to the cylinder 140 to stop running.

[0051] It can be understood that the horizontal parts 611 are each provided with a sensor connected to the central control system, which can detect whether there is a pulley on the corresponding horizontal part 611.

[0052] In addition, the sensors can also be spread all over the entire inclined groove 610. The central control system can receive the position of the pulley from the real-time feedback of the sensor.
