Description

Technical Field

[0001] The utility model relates to the technical field of foam plastic detection, and specifically relates to a centering device for automatic detection of the apparent density of foam plastics. Background Art

[0002] In the production process of foam plastics, the detection of their physical properties is an essential link, and the apparent density is a key index. Traditional detection methods often rely on manual operation, manually placing the foam plastic sample on the detection equipment. This method is not only inefficient, but also may lead to inaccurate placement of the sample due to human factors, affecting the accuracy of the detection results. In addition, for foam plastics with irregular shapes or easy to deform, it is difficult to achieve precise alignment by manual positioning, which limits the accuracy and repeatability of the detection.

[0003] Although existing automatic detection equipment can improve the detection efficiency to a certain extent, most equipment still has difficulties in centering when dealing with lightweight and easily deformable materials such as foam plastics. Especially when high-precision mechanical docking with other workstations on the detection production line is required, the automatic centering of foam plastics is particularly important. Summary of the Utility Model

[0004] Therefore, in order to solve the above problems, the purpose of the utility model is to provide a centering device for automatic detection of the apparent density of foam plastics, which includes a loading platform for placing foam plastics. Four strip-shaped grooves are circumferentially arranged on the loading platform, and the strip-shaped grooves extend along the radial direction of the loading platform. A moving piece is movably connected in the strip-shaped groove, and a clamping plate is installed at the upper end of the moving piece. The clamping plate is perpendicular to the radial direction of the loading platform.

[0005] Preferably, a driving mechanism is installed below the loading platform, and the driving mechanism is used to control the moving piece to approach / away from the center of the loading platform along the strip-shaped groove.

[0006] Preferably, the driving mechanism includes two sets of mutually perpendicular endless belts. Two follower parts are fixed on one endless belt, and the moving piece is fixed on the follower part. The two follower parts are respectively arranged on both sides of the two reversing ends of the endless belt.

[0007] Preferably, the driving mechanism further includes two rotating motors. The output ends of the rotating motors are connected with driving wheels, and the two reversing ends of the endless belt are respectively sleeved on the driving wheels and driven wheels.

[0008] Preferably, guide rails are arranged at the lower end of the loading platform at positions corresponding to the follower parts, and the follower parts are clamped on the guide rails.

[0009] Preferably, an installation plate is provided at the lower end of the loading platform. Both ends of the installation plate are bent upward and fixed to the lower end of the loading platform by bolts. A through hole is provided on the installation plate for the output end of the rotating motor to pass through, and the driving wheel is arranged between the installation plate and the loading platform.

[0010] Preferably, the upper end of the clamping plate is bent away from the center of the loading platform.

[0011] The beneficial effects of the present utility model are as follows:

[0012] Through the integrated drive mechanism and linkage mechanism, the device can automatically and accurately align the foam plastic sample to the center position of the loading platform. When the sample is placed on the platform, the driving wheel rotates to drive the circulating belt and the connected moving piece and clamping plate to move towards the center of the platform. The four clamping plates apply force evenly from different directions to ensure that the sample is quickly and accurately positioned. This automatic centering process completely eliminates the need for manual intervention, significantly shortening the sample preparation time and eliminating the errors that may be introduced by manual operation, thus significantly improving the speed and accuracy of the detection process. Once the sample is pushed to the center of the platform by the clamping plate, it is immediately ready for the next step of automatic detection without additional time for sample adjustment or repositioning, ensuring the continuity and efficiency of the detection work. Such a design not only realizes the automation of foam plastic detection, but also significantly accelerates the detection cycle and enhances the reliability of the detection results by optimizing the sample centering process.

[0022] Embodiment 1:

[0023] Figures 1 - 3 A centering device for automatically detecting the apparent density of foamed plastics provided by the present utility model is shown, including a loading platform 1. Four clamping plates 2 are movably connected to the loading platform 1. The clamping plates 2 are arranged in a circular array with the center of the loading platform 1 as the origin. The included angle between adjacent clamping plates 2 is 90°. The four clamping plates 2 move synchronously. When the four clamping plates 2 move towards the center of the loading platform 1 at the same time, the foamed plastics can be clamped and centered to complete the alignment action.

[0024] Four strip-shaped grooves 11 are circumferentially arranged on the loading platform 1. The strip-shaped grooves 11 extend along the radial direction of the loading platform 1. A moving piece 3 is movably connected in the strip-shaped grooves 11. A clamping plate 2 is installed at the upper end of the moving piece 3. The clamping plate 2 is perpendicular to the radial direction of the loading platform 1. By moving the moving piece 3 along the strip-shaped grooves 11, the clamping plate 2 is driven to move, and the movement of the clamping plate 2 realizes the functions of clamping and alignment.

[0025] To control the movement of the moving piece 3, a driving mechanism is installed below the loading platform 1. The driving mechanism is used to control the moving piece 3 to approach / away from the center of the loading platform 1 along the strip-shaped groove 11. Specifically, the driving mechanism includes two sets of mutually perpendicular endless belts 4. Two follower members 41 are fixed on one set of endless belts 4. The moving piece 3 is fixed on the follower members 41. The two follower members 41 are respectively arranged on both sides of the two reversing ends of the endless belt 4. When the endless belt 4 rotates forward, the two follower members 41 move towards the center of the loading platform 1. On the contrary, when the endless belt 4 rotates reversely, the two follower members 41 move in the direction away from the center of the loading platform 1.

[0026] The endless belt 4 is controlled by a rotating motor 5 in cooperation with a driving wheel 51 and a driven wheel 52. Specifically, the driving mechanism further includes two rotating motors 5. The output end of the rotating motor 5 is connected with the driving wheel 51. The two reversing ends of the endless belt 4 are respectively sleeved on the driving wheel 51 and the driven wheel 52. Starting the rotating motor 5 can control the driving wheel 51 to drive the endless belt 4 to rotate.

[0027] Guide rails 13 are provided at the lower end of the loading platform 1 at positions corresponding to the follower members 41. The follower members 41 are clamped on the guide rails 13. The guide rails 13 play a guiding role for the follower members 41 to prevent the follower members 41 from swinging left and right during movement.

[0028] An installation plate 6 is provided at the lower end of the loading platform 1. Both ends of the installation plate 6 are bent upwards and fixed to the lower end of the loading platform 1 by bolts. Through holes are provided on the installation plate 6 for the output end of the rotating motor 5 to pass through. The driving wheel 51 is arranged between the installation plate 6 and the loading platform. The installation plate 6 facilitates the installation and disassembly of the rotating motor 5.

[0029] The upper end of the clamping plate 2 is bent away from the center of the loading platform 1.

[0030] Working principle:

[0031] The foam plastic is grabbed by other equipment and placed on the loading platform 1. The driving mechanism controls the rotation of the driving wheel 51 to drive the endless belt 4 to rotate. The endless belt 4 drives the follower members 41, the moving piece 3, and the clamping plate 2 to move towards the center of the loading platform 1 together. The four clamping plates 2 push the foam plastic from four directions to position it at the center of the loading platform 1. The loading platform 1 has been pre-mechanically positioned with other detection stations in the equipment. Therefore, after the clamping plate 2 pushes the foam plastic to the loading platform 1, it can be aligned with other detection stations.

[0032] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
