[0002] Acrylic, also known as specially treated organic glass, is a replacement product for organic glass. Light boxes made of acrylic have the characteristics of good light transmission, pure color, rich colors, beautiful and flat, taking into account both day and night effects, long service life, and no impact on use. When using the extrusion method for production, it is necessary to continuously and dynamically measure the thickness of the finished acrylic sheet to avoid problems during the production process of the acrylic sheet.

[0003] When testing acrylic plates, a cylinder is usually used to push the limit tube to contact the top of the acrylic plate to limit it. However, when using acrylic plates of different thicknesses, the position of the cylinder needs to be adjusted to change the extension length of the limit tube, which is very inconvenient to use. Summary of the invention

[0004] The present invention aims to solve the problem that the limiting cylinder in the prior art cannot adapt to the use of acrylic plates of different thicknesses, and proposes the following technical solutions:

[0005] Acrylic plate continuous dynamic thickness measuring device, including:

[0006] A conveying module, wherein the conveying module includes a conveying device, and the conveying device is used to continuously convey the acrylic plate product in direction A;

[0007] The limit module includes a mounting frame, a limit cylinder, a fixed shaft and a sleeve cylinder, the sleeve cylinder is rotatably sleeved on the surface of the fixed shaft, and a torsion spring is arranged between the sleeve cylinder and the fixed shaft, the limit cylinder is rotatably inserted in the mounting frame, and one end of the mounting frame is fixedly connected to the sleeve cylinder;

[0008] The transmission equipment conveys the acrylic plate product through the position of the limiting module, and the acrylic plate product pushes the limiting cylinder so that the mounting frame and the sleeve cylinder deflect in the B direction with the fixed axis as the center, and the limiting module automatically limits the position above the acrylic plate product.

[0009] As a preferred embodiment of the above technical solution, the limit module further includes a decompression assembly, which includes a ratchet block, and pawl blocks are provided on both sides of the ratchet block, and the ratchet block and the pawl block block the resetting direction of the sleeve.

[0010] As a preferred embodiment of the above technical solution, the decompression assembly also includes a screw and two movable rods. The two ratchet blocks are respectively rotatably inserted into the two movable rods, and a torsion spring is arranged between the ratchet block and the movable rod. Reversely arranged threads are opened at both ends of the screw, and sliders are sleeved on the threaded surfaces at both ends of the screw, and the sliders are fixedly connected to the ends of the movable rods.

[0011] As a preferred embodiment of the above technical solution, the limit module further includes a mounting seat, both ends of the fixed shaft are fixedly connected to the mounting seat, and the mounting seat is fixedly connected to the central control module.

[0012] As a preferred embodiment of the above technical solution, a storage cavity is provided inside the limiting cylinder, and the storage cavity carries coolant. External connecting pipes for replacing the coolant are rotatably sleeved at both ends of the limiting cylinder.

[0013] As a preferred embodiment of the above technical solution, a thickness measuring module is also included, and the thickness measuring module includes a plurality of sensors, and the plurality of sensors are installed in the transmission equipment and are located on the upper and lower sides of the acrylic plate product.

[0014] As a preferred embodiment of the above technical solution, it also includes a central control module, which is installed on the top of the transmission equipment. The central control module is used to receive the information transmitted by the thickness measuring module and calculate the thickness of the acrylic plate product here, summarize the thickness information of the acrylic plate products passing continuously, and obtain the overall thickness information change of the dynamically moving acrylic plate product.

[0015] The working method of the acrylic plate continuous dynamic thickness measuring device comprises the following steps:

[0016] S1. Product transportation;

[0018] S2, product limit;

[0019] The mounting frame and the sleeve tube deflect in the direction B with the movement of the limit tube around the fixed axis, and the pawl block slides on the surface of the ratchet block.

[0020] S3, continuous thickness measurement of products;

[0021] In addition, multiple sensors located on the upper and lower sides of the acrylic sheet product transmit information to the central control module. The central control module summarizes the thickness information of the acrylic sheet products passing continuously to obtain the overall thickness information change of the dynamically moving acrylic sheet product.

[0022] The beneficial effects of the present invention are:

[0023] 1. Use the passing of the acrylic plate product to push the limit cylinder upward to make it move upward and fall on the upper surface of the acrylic plate product.

The limit module can automatically adjust according to the thickness of the acrylic plate product. At the same time, with the cooperation of the ratchet block and the pawl block, the reverse reset rotation direction of the sleeve cylinder is limited to avoid excessive extrusion of the acrylic plate product due to the torsion force of the torsion spring during the lifting process of the sleeve cylinder, thereby avoiding excessive friction with the surface of the acrylic plate and damaging its surface;

[0024] 2. Move the two pawl blocks in the opposite direction away from the ratchet block position. The torsion spring located between the sleeve and the fixed shaft can be twisted and reset to push the sleeve to automatically reset. The limit cylinder then returns to the initial position to match the acrylic plate products of different thicknesses. The limit module is easy to adjust and has stronger applicability and is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings of the specification.

[0032] Example

[0033] Figure 1-Figure 4 The acrylic plate continuous dynamic thickness measuring device is characterized by comprising:

[0034] A conveying module, wherein the conveying module comprises a conveying device 10, and the conveying device 10 is used for continuously conveying acrylic plate products in direction A;

[0035] The limiting module includes a mounting frame 21, a limiting cylinder 22, a fixed shaft 23 and a sleeve cylinder 24. The sleeve cylinder 24 is rotatably sleeved on the surface of the fixed shaft 23, and a torsion spring is provided between the sleeve cylinder 24 and the fixed shaft 23. The limiting cylinder 22 is rotatably inserted in the mounting frame 21, and one end of the mounting frame 21 is fixedly connected to the sleeve cylinder 24.

[0036] The transmission device 10 transports the acrylic plate product through the position of the limiting module. The acrylic plate product pushes the limiting cylinder 22 so that the mounting frame 21 and the sleeve cylinder 24 deflect in the direction B with the fixed axis 23 as the center, and the limiting module automatically limits the position above the acrylic plate product.

[0037] It also includes a thickness measuring module, which includes a plurality of sensors 30. The plurality of sensors 30 are installed in the transmission device 10 and are located at the upper and lower sides of the acrylic plate product.

[0038] It also includes a central control module 40, which is installed on the top of the transmission equipment 10. The central control module 40 is used to receive the information transmitted by the thickness measuring module and calculate the thickness of the acrylic plate product here, summarize the thickness information of the acrylic plate products passing continuously, and obtain the overall thickness information change of the dynamically moving acrylic plate product.

[0039] When acrylic sheet products of different thicknesses need to be produced, the external basic production equipment will continuously extrude acrylic sheet products of corresponding thicknesses, and the products will be continuously transported through the transmission equipment 10. The end of the incoming acrylic sheet product will contact the limiting cylinder 22 and push it up. The mounting frame 21 and the sleeve cylinder 24 will deflect in the direction B with the fixed axis 23 as the center as the limiting cylinder 22 moves, and multiple sensors 30 located on the upper and lower sides of the acrylic sheet product will transmit information to the central control module 40. The central control module 40 will summarize the thickness information of the acrylic sheet products that pass continuously to obtain the overall thickness information change of the dynamically moving acrylic sheet product.

[0040] The passing of the acrylic plate product is used to push the limiting cylinder 22 upward to make it move upward and fall on the upper surface of the acrylic plate product. The upper surface of the acrylic plate product is limited under the action of the limiting module's own gravity. The limiting module can automatically adjust according to the thickness of the acrylic plate product.

[0041] The working method of the acrylic plate continuous dynamic thickness measuring device comprises the following steps:

[0042] S1. Product transportation;

[0043] The external basic production equipment continuously conveys the acrylic sheet product through the transmission device 10, and the end of the incoming acrylic sheet product contacts the limiting cylinder 22 and pushes it upward;

[0044] S2, product limit;

[0045] The mounting frame 21 and the sleeve tube 24 deflect in the direction B with the movement of the limiting tube 22 around the fixed axis 23, and the pawl block 262 slides on the surface of the ratchet block 261 accordingly. The restriction of the ratchet block 261 and the pawl block 262 on the sleeve tube 24 can prevent the limiting module from over-extruding the acrylic plate product;

[0046] S3, continuous thickness measurement of products;

[0047] And multiple sensors 30 located on the upper and lower sides of the acrylic plate product transmit information to the central control module 40, and the central control module 40 summarizes the thickness information of the acrylic plate products passing continuously to obtain the overall thickness information change of the dynamically moving acrylic plate product.

[0048] Figure 2-Figure 5 In the embodiment, the limit module further includes a decompression assembly 26, which includes a ratchet block 261. Both sides of the ratchet block 261 are provided with pawl blocks 262. The ratchet block 261 and the pawl block 262 block the reset direction of the sleeve 24.

[0049] When the limiting cylinder 22 is pushed upward, the mounting frame 21 and the sleeve cylinder 24 deflect in direction B around the fixed axis 23 as the limiting cylinder 22 moves, and the pawl block 262 slides on the surface of the ratchet block 261. After the position adjustment of the limiting cylinder 22 is completed, the ratchet block 261 and the pawl block 262 block the resetting direction of the sleeve cylinder 24.

[0050] With the cooperation of the ratchet block 261 and the pawl block 262, the direction of the reverse reset rotation of the sleeve 24 is limited to prevent the acrylic plate product from being excessively squeezed by the torsional force of the torsion spring during the lifting of the sleeve 24, thereby avoiding excessive friction with the surface of the acrylic plate and damaging its surface.

[0051] Figure 4-Figure 5 In the figure, the decompression assembly 26 also includes a screw rod 263 and two moving rods 264. The two ratchet blocks 262 are respectively rotated and inserted into the two moving rods 264, and a torsion spring is arranged between the ratchet block 262 and the moving rod 264. The two ends of the screw rod 263 are provided with reversely arranged threads, and the threaded surfaces at both ends of the screw rod 263 are both sleeved with sliders 265, and the sliders 265 are fixedly connected to the ends of the moving rods 264.

[0052] Before producing acrylic plate products of different thicknesses, the screw 263 is rotated to drive the two sliders 265 to move in the opposite direction, and the moving rod 264 then drives the pawl block 262 to leave the groove of the ratchet block 261, and the torsion spring located between the sleeve tube 24 and the fixed shaft 23 is twisted and reset, and the limit tube 22 then returns to the initial position.

[0053] Move the two pawl blocks 262 in the opposite direction away from the position of the ratchet block 261, and the torsion spring located between the sleeve tube 24 and the fixed shaft 23 can be twisted and reset to push the sleeve tube 24 to automatically reset, and the limit tube 22 returns to the initial position to be used with acrylic plate products of different thicknesses. The limit module is easy to adjust and has stronger applicability and is more convenient to use.

[0054] Figure 2 In the embodiment, the limit module further includes a mounting seat 25 , both ends of the fixed shaft 23 are fixedly connected to the mounting seat 25 , and the mounting seat 25 is fixedly connected to the central control module 40 .

[0055] The mounting seat 25 is used to mount the limiting module, and the initial position of the limiting cylinder 22 is adjusted by adjusting the mounting position of the mounting seat 25 .

[0056] Figure 2-Figure 4 In the embodiment, a storage chamber 221 is provided inside the limiting cylinder 22, and the storage chamber 221 carries coolant inside. External connecting pipes for replacing coolant are rotatably sleeved at both ends of the limiting cylinder 22.

[0057] The storage cavity 221 provided inside the limiting cylinder 22 can store or pass a certain amount of coolant, which can cool the surface of the limiting cylinder 22 and dissipate the heat generated by the rolling friction of the limiting cylinder 22, thereby preventing the limiting cylinder 22 from overheating and affecting the acrylic plate product.

[0058] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
