Abstract
Description
Technical Field
[0001] This utility model relates to the field of materials testing technology, and in particular to a plastic film thickness testing device. Background Technology
[0002] A plastic film thickness detection device is an instrument that uses optical and electrical principles, along with corresponding sensors and a supporting data processing system, to detect plastic films in a non-contact manner and convert the relevant information into a thickness value. It typically has a circular guide rail, with a capacitive sensor mounted on a sliding block that slides along the rail. During this process, the sensor maintains a certain relative position to the film, using the principle of capacitance to continuously and in real-time detect the film thickness. The capacitance change signal detected by the sensor is transmitted to the control system, which then calculates the film thickness value. On a film production line, if a capacitive sensor suddenly malfunctions, its internal circuitry short-circuiting and preventing it from outputting any measurement signal, the bolted sensor requires tools to loosen the bolts one by one to remove the faulty sensor. Since the production line cannot be shut down for an extended period for repair, this situation severely impacts production efficiency and product quality. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0030] Example 1
[0031] Reference Figures 1 to 8 This is the first embodiment of the present invention. This embodiment provides a plastic film thickness detection device, which includes a main body component 100 and a clamping component 200. The two work together to quickly disassemble and assemble when the capacitive sensor on the film production line is damaged, which can avoid the production line from being shut down for too long due to maintenance, maintain operation and reduce the impact on production efficiency and product quality.
[0032] The main component 100 includes a detector 101, a rotating frame 102 is provided above the detector 101, and a gripper 103 is provided at the bottom of the rotating frame 102.
[0033] The detector 101 integrates sensors and a data processing system, which are responsible for receiving signals and calculating the film thickness value to realize measurement and data-related operations. There are two grippers 103, which are respectively set at both ends of the rotating frame 102. By placing the grippers 103 on the guide rail, and then moving the rotating frame 102 to drive the grippers 103 to move on the slide rail, the detector 101 can be driven to rotate around the film to detect its thickness. The detector 101 is existing technology and will not be described in detail here.
[0034] The clamping assembly 200 is mounted on the detector 101 and includes a clamping member 201 and a clamping plate 201a. The clamping plate 201a is mounted on one side of the detector 101. A driving block 201b is fixed to the top of the clamping plate 201a. A hinge rod 201c is mounted on one side of the driving block 201b. The driving block 201b and the hinge rod 201c are hinged together. A movable block 201d is hinged to one end of the hinge rod 201c.
[0035] There are two sets of clamping components 201, both of which are mounted on the detector 101. When it is necessary to fix the detector 101, the movable block 201d is moved. At this time, the movable block 201d can drive the two hinge rods 201c to move towards each other. Then, the movement of the hinge rods 201c can drive the drive block 201b to move. The movement of the drive block 201b will drive the clamping plate 201a to move towards each other. A friction pad is provided on one side of the clamping plate 201a. The friction pad is made of silicone and has a textured surface to increase friction. By moving the clamping plate 201a to one side of the detector 101, it can be fixed.
[0036] Example 2
[0037] Reference Figures 2-8 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0038] Specifically, the clamping assembly 200 also includes a support member 202, which includes a pulley 202a. The pulley 202a and the top of the clamping plate 201a are rotatably connected by a pivot, and a positioning frame 202b is sleeved on the outside of the pulley 202a.
[0039] There are two pulleys 202a, both located on the top of the clamping plate 201a. There are two positioning frames 202b, both fixed to the bottom of the support frame 202c. The pulleys 202a slide within the positioning frames 202b. When the clamping plate 201a moves, the pulleys 202a can slide within the positioning frames 202b, thereby supporting the clamping plate 201a and preventing it from shifting during movement.
[0040] Specifically, a support frame 202c is fixed to the top of the positioning frame 202b, the support frame 202c is fixed to the bottom of the rotating frame 102, and a slide rail 202d is provided at the bottom of the driving block 201b, with the driving block 201b and the slide rail 202d slidably connected.
[0041] The positioning frame 202b can be supported by the support frame 202c. Both the moving block 201d and the driving block 201b slide on the slide rail 202d. The slide rail 202d can support both of them and prevent them from shifting during movement.
[0042] Specifically, the clamping assembly 200 also includes a driving component 203, which includes a movable rod 203a. The movable rod 203a is fixed to one side of the movable block 201d, and a connecting block 203b is fixed to one end of the movable rod 203a.
[0043] When it is necessary to move the movable block 201d to clamp the detector 101, the connecting block 203b is moved. At this time, the movement of the connecting block 203b can drive the movable rod 203a to move, and the movement of the movable rod 203a can drive the movable block 201d to move to clamp the detector 101.
[0044] Specifically, a positioning box 203c is fitted on the outer side of the movable rod 203a, and the movable rod 203a and the positioning box 203c are movably connected.
[0045] The positioning box 203c is fixed to one side of the rotating frame 102. The positioning box 203c can support the movable rod 203a and prevent the movable rod 203a from shifting when moving.
[0046] Specifically, a connecting strip 203d is fixed to the top of the connecting block 203b, a movable frame 203e is fixed to the top of the connecting strip 203d, and a drive rod 203f is hinged inside the movable frame 203e.
[0047] Moving the drive rod 203f releases the limit on the movable rod 203a, allowing the movable block 201d to move and clamp the detector 101. Moving the drive rod 203f moves the movable frame 203e, which in turn moves the connecting bar 203d. The movement of the connecting bar 203d moves the connecting block 203b, which in turn moves the movable rod 203a, which in turn moves the movable block 201d.
[0048] Specifically, a torsion spring 203g is fixed to the bottom of the drive rod 203f, one end of the torsion spring 203g is fixed to the inner wall of the movable frame 203e, and a pressing rod 203h is fixed to one side of the drive rod 203f.
[0049] When the drive rod 203f is moved to release the limit on the movable rod 203a, a torsional force can be applied to the torsion spring 203g. After the movable rod 203a is moved to the designated position to fix the clamping plate 201a to the detector 101, the drive rod 203f is released. At this time, the force of the rotation of the torsion spring 203g drives the drive rod 203f back to its original position, thereby limiting the movable rod 203a again and preventing the movable rod 203a from moving on its own and causing the clamping of the detector 101 to loosen. The setting of the pressing rod 203h makes it convenient for the user to move the drive rod 203f.
[0050] Example 3
[0051] Reference Figures 1 to 8 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0052] Specifically, the clamping assembly 200 also includes a limiting member 204, which includes a translation frame 204a, and the translation frame 204a and the drive rod 203f are hinged at one end.
[0053] When the drive rod 203f moves, it can drive the translation frame 204a to move. At this time, the movement of the translation frame 204a can release the limit on the movable rod 203a.
[0054] Specifically, a limiting block 204b is fixed on one side of the translation frame 204a, and a limiting plate 204c is provided on one side of the limiting block 204b. The limiting plate 204c is fixed to the inner wall of the positioning box 203c.
[0055] The limiting plate 204c has a limiting groove on one side corresponding to the limiting block 204b. When the translation frame 204a moves, it can drive the limiting block 204b to move and separate from the limiting groove. At this time, the limiting of the movable rod 203a can be released. When the drive rod 203f is released, the force of the torsion spring 203g rotating will drive the drive rod 203f to return to its original position, thereby driving the limiting block 204b to engage with the limiting groove, thus limiting the movable rod 203a again.
[0056] Specifically, a guide strip 204d is fixed to the top of the translation frame 204a, and a guide block 204e is sleeved on the outside of the guide strip 204d. The guide strip 204d and the guide block 204e are movably connected.
[0057] A guide groove corresponding to the guide bar 204d is provided on the guide block 204e. The guide bar 204d slides in the guide groove. When the translation frame 204a moves, it can drive the guide bar 204d to slide in the guide groove, thereby supporting the translation frame 204a and preventing the translation frame 204a from shifting.
[0058] In use, the detector 101 is first placed on one side of the clamping plate 201a. When it is necessary to fix the detector 101, the pressing rod 203h is pressed, which drives the drive rod 203f to move. The torsion spring 203g at the bottom of the drive rod 203f will be subjected to a torsional force due to the movement of the drive rod 203f. The movement of the drive rod 203f drives the translation frame 204a to move. When the translation frame 204a moves, it can drive the guide strip 204d to slide in the guide groove, thereby supporting the translation frame 204a. The movement of the translation frame 204a drives the limiting block 204b on one side to move. This causes the limiting block 204b to separate from the corresponding limiting groove on the limiting plate 204c, thereby releasing the limitation on the movable rod 203a. Then, the movement of the movable rod 203a causes the connecting block 203b to move, which in turn causes the movable rod 203a to move. The movement of the movable rod 203a causes the movable block 201d to move, which in turn causes the hinge rod 201c to move towards each other. The movement of the hinge rod 201c causes the driving block 201b to move, which in turn causes the clamping plate 201a to move towards each other until the clamping plate 201a contacts and clamps the detector 101, thus completing the fixation of the detector 101.
[0059] After the detector 101 is fixed, the pressing rod 203h is released. The force of the torsion spring 203g rotating drives the drive rod 203f back to its original position, so that the limiting block 204b re-engages with the limiting groove, and limits the movable rod 203a again to prevent the clamping of the detector 101 from loosening.
[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
