Description

Technical Field

[0001] This utility model relates to the technical field of thickness calibration devices, specifically to a thickness calibration device for plastic PP sheets. Background Technology

[0002] A PP sheet thickness calibration device is a precision measuring instrument or system designed to ensure that the thickness uniformity, consistency, and absolute value of PP sheets coming off the production line are strictly controlled within the tolerance range required by customers or international / national standards. It is specifically used to detect, measure, verify, and calibrate whether the thickness of polypropylene sheets meets specified standards. Traditional thickness calibration methods require stopping the machine or taking a small sample at the end of the production line and measuring at a limited number of points with calipers or micrometers. This results in low production efficiency, high labor costs, large human error, significant lag, inability to achieve real-time control, and easy waste of production raw materials and energy. Utility Model Content

[0003] The purpose of this invention is to provide a plastic PP sheet thickness calibration device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a plastic PP sheet thickness calibration device, comprising six vibration isolators, a base plate fixedly installed on the top of the six vibration isolators, and a bracket, a standard gauge block set and a flattening assembly are fixedly installed sequentially from the outside to the inside on the top of the base plate, a first motor fixedly installed on the left side of the outer wall of the bracket, and a detection assembly provided at the output end of the first motor, a second motor fixedly installed on the front side of the outer wall of the bracket, and a moving assembly provided at the output end of the second motor, and a moving assembly provided on the inner side of the detection assembly.

[0005] The beneficial effects of this utility model are as follows: the device can maintain the overall stability of the equipment through vibration isolators, drive the plate to move through multiple synchronous pulleys, drive the flattening roller to press down and flatten the material through piston rod, and drive multiple laser sensors on the C-shaped reinforcement frame to perform thickness detection and calibration of the material through gear linkage. The signal is transmitted to the control panel to control the start and stop of each motor and warning light, thereby reducing resource waste, realizing real-time control, and improving production efficiency.

[0006] To enable multiple laser sensors to detect the overall thickness of the material and reduce downtime: The detection assembly is further configured as follows: the detection component includes a first lead screw, the two ends of which are movably inserted into the outer wall of the bracket; a first gear is provided at the right end of the first lead screw; the first gear is connected to a second gear in front of it via a first toothed belt; a second lead screw is provided at the left axis of the second gear; and a C-shaped reinforcement frame is threadedly connected to the outer wall of the second lead screw; multiple laser sensors are equidistantly provided on both the upper and lower sides of the inner wall of the C-shaped reinforcement frame; a control panel is provided on the front side of the C-shaped reinforcement frame; and multiple warning lights are equidistantly provided on the top of the C-shaped reinforcement frame.

[0007] By adopting the above technical solution, the first motor drives the first lead screw to rotate, and then drives the second lead screw on the shaft of the second gear to rotate synchronously through the first gear and the first toothed belt. This causes the C-shaped reinforcement frame to move left and right along the outer wall of the first and second lead screws through the trapezoidal nut. Multiple laser sensors perform real-time thickness detection on the entire material, improving detection uniformity and efficiency.

[0008] To enable the driven roller to move the material: The moving component is further configured such that: the moving component includes a rotating shaft, the two ends of the rotating shaft are movably inserted into the top of the bracket, the outer wall of the rotating shaft is provided with a driving roller and a first synchronous pulley from front to back, the first synchronous pulley is connected to a plurality of parallel second synchronous pulleys on the right side through a toothed belt, the shaft of the plurality of second synchronous pulleys is provided with a fixed shaft, and the two ends of the fixed shaft are movably inserted into the top of the bracket, and the center of the outer wall of the fixed shaft is provided with a driven roller.

[0009] By adopting the above technical solution, the second motor drives the rotating shaft on the output end to rotate, which in turn drives the coaxial active roller to rotate. The first synchronous pulley on the coaxial active roller drives multiple parallel second synchronous pulleys to rotate synchronously through the toothed belt, so that multiple driven rollers rotate synchronously, thereby improving the overall material detection and conveying efficiency.

[0010] To achieve overall flattening of the material by the flattening rollers and prevent curling during material conveying: The flattening assembly is further configured such that: the bottom of the hydraulic pump is fixedly installed at the top center of the base plate, and the inlet of the hydraulic pump is fixedly connected to and communicates with the hydraulic cylinder behind it through a pipe; the outlet of the hydraulic pump is fixedly connected to and communicates with the piston rod on its left side through a pipe; a movable plate is fixedly installed on the top of the piston rod; fixed frames are provided on both the left and right sides of the movable plate; and flattening rollers are movably inserted into the inner wall of the fixed frames.

[0011] By adopting the above technical solution, the hydraulic pump pumps the oil in the hydraulic cylinder into the piston rod, the piston rod moves up and down to raise and lower the moving plate, and then drives the flattening roller to move up and down to appropriately flatten the material being conveyed, thereby improving the accuracy of material thickness calibration measurement.

[0012] To ensure that the C-shaped reinforcement frame moves in a consistent manner on both the front and rear sides: The configuration is further defined as follows: the bottom of the C-shaped reinforcing frame is movably sleeved on the second lead screw, and the left and right ends of the second lead screw are movably inserted into the outer wall of the bracket, while the first lead screw and the second lead screw remain horizontal and parallel to each other.

[0013] By adopting the above technical solution, the left and right ends of the second lead screw and the first lead screw are movably inserted into the bracket. The bracket provides support and stability for the synchronous rotation of the second lead screw and the first lead screw, thereby driving the front and rear sides of the C-shaped reinforcement frame to move synchronously and stably, thereby improving the efficiency of testing and calibration.

[0014] To achieve stable vertical movement of the fixed frame: The bracket is further configured such that: the outer wall of the bracket has a groove whose inner wall size matches the outer wall size of the T-shaped block of the fixing frame, and the outer wall of the bracket has a hole whose inner wall size matches the outer wall size of the rotating shaft and the fixing shaft.

[0015] By adopting the above technical solution, multiple T-shaped blocks on the fixed frame are movably engaged in the groove of the bracket. The groove of the bracket provides support and limit for the up and down movement of the fixed frame, thereby improving the stability of the fixed frame when it moves on the bracket and improving the flattening efficiency.

[0016] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0026] The computer software involved in the hardware carriers such as the first motor in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.

[0027] Therefore, the "first motor," "second motor," etc. involved in this application are physical functional modules that combine computer software programs or protocols in the prior art with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction relationship between the various physical functional modules, that is, the improvement of the overall structure of the plastic PP sheet thickness calibration device of this application, so as to solve the corresponding technical problems to be solved by this application.

[0028] The working process of this plastic PP sheet thickness calibration device is as follows: First, the worker places one end of the material on the driven or driven roller 902. The control panel 706 integrates a PLC controller, display screen, multiple switches, and antenna. The control panel 706 is electrically connected to each motor and multiple warning lights 707. Then, the external power supply is turned on, and six vibration isolators 1 reduce the interference of external vibrations on the equipment. The gauge blocks are taken out from the standard gauge block set 4, and the laser sensor 705 is calibrated. Then, the second motor 8 and hydraulic pump 501 are started. The second motor 8 drives the rotating shaft 901 on the output end to rotate, which in turn drives the coaxial driven roller 902 to rotate. The first synchronous pulley 903, coaxial with the toothed belt 904, drives multiple parallel second synchronous pulleys 905 to rotate synchronously, causing multiple driven rollers to rotate synchronously and move the material as a whole to the top of the support 3. The hydraulic pump 501 pumps oil from the hydraulic cylinder into the piston rod 502, which lifts and lowers the moving plate 503. Multiple T-blocks on the fixed frame 504 are movably engaged in the grooves of the support 3. The grooves of the support 3 provide support and limit for the vertical movement of the fixed frame 504, thereby improving the stability of the fixed frame 504 when it moves on the support 3. The flattening rollers 505 on the fixed frame 504 move accordingly. The device moves up and down to moderately flatten the material being conveyed. Then, the first motor 6, equipped with a position encoder at its tail, is activated. The first motor 6 drives the first lead screw 701 to rotate, which in turn drives the second lead screw on the shaft of the second gear 703 to rotate synchronously via the first gear 702 and the first toothed belt. This causes the C-shaped reinforcing frame 704 to move left and right along the outer walls of the first and second lead screws via a trapezoidal nut. The outer wall of the C-shaped reinforcing frame 704 is movably fitted onto a sliding rod located on the front side of the bracket 3. The sliding rod, the first lead screw 701, and the second lead screw work together to improve the movement of the C-shaped reinforcing frame 704. To ensure stability, multiple laser sensors 705 on the C-shaped reinforcement frame 704 perform real-time multi-point thickness detection and calibration of the material, and display the detection results on the display screen of the control panel 706. When the material thickness is uneven, the control panel 706 records the data and feeds the signal back to the controllers of other equipment on the production line through the antenna. At the same time, the first motor 6 is turned off, and multiple warning lights 707 at the corresponding laser sensor 705 positions flash to remind the staff. The staff can check the data on the control panel 706 to calibrate the thickness of subsequent material production, thereby improving the overall production efficiency.
