Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of processing equipment of plastic product. BACKGROUND

[0002] Various plastic products are generally formed by thermoforming work station, and then cut out by cutting device. Before plastic sheet enters into forming work station, it needs to be heated and softened, and the work of heating and softening is completed by plastic sheet heating work station. Generally, plastic sheet heating is by moving up and down two heating plates to press plastic sheet for heating. The motor driving heating plate to move up and down is generally rotary motion, and without adjusting the position of motor, the initial position of heating plate cannot be adjusted. However, plastic products have different thickness, so different initial position of heating plate is needed. In this case, the position of motor can only be adjusted, which is very inconvenient. SUMMARY

[0003] In view of the deficiencies in the prior art, the utility model innovatively provides a plastic sheet heating servo work station convenient to adjust.

[0004] The plastic sheet heating servo work station comprises a base, a top plate, a stand, a movable plate, an upper heating plate and a lower heating plate, and a servo motor. The upper end of the stand is connected to the top plate, and the lower end of the stand is connected to the base. The upper heating plate is connected to the bottom of the top plate. The lower heating plate is connected to the movable plate. The movable plate is movably arranged on the stand through a guide sleeve. The servo motor is drivingly connected to the movable plate through a transmission assembly. The servo motor can control the movable plate to move up and down within a set range through the transmission assembly.

[0005] The transmission assembly comprises an upper connecting arm, a lower connecting arm, a side connecting arm and a transmission connecting arm. The upper end of the upper connecting arm is hingedly connected to the movable plate. The lower end of the upper connecting arm is connected to the upper end of the lower connecting arm through a hinge shaft. The lower end of the lower connecting arm is hingedly connected to the base. The upper connecting arm and the lower connecting arm are provided with two groups of hinge shafts. The two ends of the side connecting arm are hingedly connected to the two groups of hinge shafts. The upper end of the transmission connecting arm is connected to the middle part of the side connecting arm. The lower end of the transmission connecting arm is drivingly connected to the servo motor.

[0006] The servo motor drives the transmission connecting arm to swing at a set angle.

[0007] A support is installed on the base, and a feeding roller group is installed on the support. The feeding roller group is located on the feeding side of the movable plate. The feeding roller group comprises an upper feeding roller, a lower feeding roller and a feeding motor. The feeding motor drives the lower feeding roller to rotate. The upper feeding roller cooperates with the lower feeding roller to feed.

[0008] A fixing plate is installed on the bracket, the upper feeding roller is rotatably mounted on the roller seat, and the roller seat is adjustable up and down on the fixing plate.

[0009] According to the plastic sheet heating servo workstation provided by this utility model, the pressing position of the heating plate can be controlled simply by controlling the rotation angle of the servo motor, thereby meeting the heating requirements of plastic products of different thicknesses.

[0011] Figure 2 The three-dimensional representation of this utility model Figure 2 . Detailed Implementation

[0012] like Figure 1 As shown, this plastic sheet heating servo workstation includes a base 6, a top plate 1, a column 5, a movable plate 4, an upper heating plate 2, a lower heating plate 3, and a servo motor. The upper end of the column 5 is connected to the top plate 1, and the lower end of the column 5 is connected to the base 6. The upper heating plate 2 is connected to the bottom of the top plate 1, and the lower heating plate 3 is connected to the movable plate 4. The movable plate 4 is movably mounted on the column 5 via a guide sleeve 40. The servo motor is connected to the movable plate 4 via a transmission assembly 7, which controls the movable plate 4 to move up and down within a set range. During operation, the servo motor drives the movable plate 4 to move up and down, so that the lower heating plate 3 on the movable plate 4 and the upper heating plate 2 on the top plate 1 press the plastic sheet together for heating and softening. When heating plastic sheets of different thicknesses, only the rotation angle of the output shaft of the servo motor needs to be controlled to control the maximum rising position of the movable plate 4, thus controlling the pressing distance between the lower heating plate 3 and the upper heating plate 2, thereby meeting the heating requirements of plastic sheets of different thicknesses. Of course, the rotation angle of the servo motor's output shaft can be controlled by adjusting the servo motor's control program (the servo motor's control program is existing technology and is implemented through programming). In this way, the maximum rising position of the movable plate 4 can be controlled simply by adjusting the servo motor's control program, making adjustment very convenient.

[0013] like Figure 1As shown, the transmission assembly 7 of this utility model includes an upper connecting arm 71, a lower connecting arm 72, a side connecting arm 74, and a transmission connecting arm 75. The upper end of the upper connecting arm 71 is hinged to the movable plate 4, and the lower end of the upper connecting arm 71 is connected to the upper end of the lower connecting arm 72 via a hinge shaft 73. The lower end of the lower connecting arm 72 is hinged to the base 6. The upper connecting arm 71 and the lower connecting arm 72 are provided in two sets, one in front and one behind. The two ends of the side connecting arm 74 are respectively hinged to the hinge shafts 73 of the two sets. The upper end of the transmission connecting arm 75 is connected to the middle of the side connecting arm 74, and the lower end of the transmission connecting arm 75 is connected to a servo motor. By driving the transmission connecting arm 75 to swing through the servo motor, the side connecting arm 74, the lower connecting arm 72, and the upper connecting arm 71 can be driven to move the movable plate 4 up and down.

[0014] Of course, in order to facilitate the adjustment of the maximum rising position of the movable plate 4, the servo motor drives the transmission connecting arm 75 to swing at a set angle instead of rotating a full circle.

[0015] In addition, such as Figure 2 As shown, a bracket 9 is installed on the base 6, and a feeding roller group 8 is installed on the bracket 9. The feeding roller group 8 is located on the feeding side of the movable plate 4. The feeding roller group 8 includes an upper feeding roller 80, a lower feeding roller 81, and a feeding motor. The feeding motor drives the lower feeding roller 81 to rotate, and the upper feeding roller 80 and the lower feeding roller 81 cooperate to send the plastic sheet between the upper heating plate 2 and the lower heating plate 3.

[0016] Finally, it is worth mentioning that a fixing plate 10 is installed on the bracket 9, and the upper feeding roller 80 is rotatably mounted on the roller seat 82. The roller seat 82 is vertically adjustable and mounted on the fixing plate 10. By adjusting the vertical position of the roller seat 82 on the fixing plate 10, the distance between the upper feeding roller 80 and the lower feeding roller 81 can be adjusted, thereby meeting the feeding requirements of plastic sheets of different thicknesses.
