Description

Technical Field

[0001] This utility model relates to the technical field of composite membrane testing equipment, specifically a composite membrane quality testing device. Background Technology

[0002] Quality testing of composite membranes generally includes properties such as appearance, thickness, mechanical properties, heat sealing, barrier properties, and hygiene. Tensile testing is a common method for testing composite membranes, which can evaluate their mechanical properties by measuring the tensile strength and elongation at break of the composite membrane.

[0003] Patent (CN220322947U) discloses a tensile strength testing device for laminated film, relating to the field of tensile strength testing technology for photovoltaic encapsulation films. The lower clamping assembly includes a fixed plate, on which an L-shaped fixed plate is bolted. A sliding L-shaped frame is symmetrically arranged on one side of the L-shaped fixed plate. The L-shaped fixed plate has protruding ears at both ends near the sliding L-shaped frame, and a photovoltaic encapsulation film fixing shaft is movably connected between the two protruding ears via a bearing. When fixing the photovoltaic encapsulation film, one end of the photovoltaic encapsulation film is first inserted into the through groove in the middle of the photovoltaic encapsulation film fixing shaft. The handle is rotated to rotate the photovoltaic encapsulation film, causing it to wrap around the photovoltaic encapsulation film fixing shaft. Then, the sliding L-shaped frame is closed with the L-shaped fixed plate, thus fixing the photovoltaic encapsulation film. The other end of the photovoltaic encapsulation film is then fixed to the upper clamping assembly in the same way. This fixing method is relatively reliable and prevents the photovoltaic encapsulation film from detaching.

[0004] The tensile testing device for laminated film in the aforementioned patent requires manual operation by staff to hold the composite film during tensile testing. This operation is cumbersome and seriously affects the efficiency of the test. Utility Model Content

[0005] The purpose of this invention is to provide a composite membrane quality testing device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a composite membrane quality testing device, including a frame and a clamping assembly. The frame is provided with a lifting adjustment assembly. The clamping assembly includes a cylinder and a first clamping frame and a second clamping frame distributed vertically. The second clamping frame is fixedly connected to the output end of the lifting adjustment assembly. The first clamping frame and the second clamping frame are respectively symmetrically provided with a first clamping plate and a second clamping plate that are movably connected. The output end of the cylinder is fixedly connected to the outer wall of a first clamping plate. The two first clamping frames are slidably connected by a plurality of vertically arranged guide rods. The top of the second clamping frame is horizontally provided with a guide groove that matches the guide rods.

[0007] Furthermore, the first clamping frame and the second clamping frame are arranged symmetrically from top to bottom. Both the first clamping plate and the second clamping plate are L-shaped structures. The bottom center of the first clamping frame is provided with a rotatably connected gear. The outer wall of the horizontal section of the first clamping plate and the second clamping plate is provided with racks that mesh with the gear, and the two racks are located on both sides of the gear.

[0008] Furthermore, the outer walls of the horizontal sections of the first clamping plate and the second clamping plate are provided with sliders, and the outer walls of the first clamping frame and the second clamping frame are both provided with horizontal slide rails that match the sliders.

[0009] Furthermore, the outer wall of the first clamping plate is provided with a plurality of limiting members on the side near the second clamping plate, and the outer wall of the second clamping plate is provided with limiting grooves that match the limiting members.

[0010] Furthermore, the limiting member is a hemispherical protrusion, the limiting groove is a hemispherical groove, and the distance between two adjacent limiting members is equal to the outer diameter of the hemispherical protrusion.

[0011] Furthermore, the limiting member is a strip-shaped limiting strip, the limiting groove is a strip-shaped groove, and the cross-section of the limiting member is a semi-circular structure.

[0012] Furthermore, the lifting adjustment assembly includes a servo motor and a vertically arranged ball screw and guide rod. A screw nut is movably fitted on the outer wall of the ball screw. The output shaft of the servo motor is fixedly connected to one end of the ball screw. A guide sleeve is slidably fitted on the outer wall of the guide rod.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] 1. This utility model comprises a lifting adjustment component, a clamping component, a first clamping frame, a second clamping frame, a first clamping plate, a second clamping plate, and a cylinder. The first and second clamping plates work together to clamp and fix the composite film. The extension and retraction of the cylinder can drive one of the first clamping plates to move horizontally back and forth. This first clamping plate, through a guide rod, drives the first clamping plate on the second clamping frame to move horizontally back and forth, so that the first and second clamping frames can clamp or loosen synchronously, achieving simultaneous clamping and fixing of the upper and lower ends of the composite film, which is convenient and quick to operate. After the composite film is clamped and fixed, the lifting adjustment component is activated, which drives the second clamping frame to move upward, and the distance between the first and second clamping frames gradually increases, which can effectively realize the tensile testing of the composite film.

[0015] 2. In this utility model, during the horizontal reciprocating motion of the first clamping plate, the rack reciprocates horizontally along with the first clamping plate. The rack drives the gear to rotate, and the gear drives another rack to reciprocate horizontally. This rack drives the second clamping plate to reciprocate horizontally. The two racks move in opposite directions, causing the first and second clamping plates to move in opposite directions. This allows the first and second clamping plates to move synchronously to clamp or release the composite film, making the operation convenient and quick. When the first and second clamping plates clamp the composite film, the limiting member pushes the composite film into the limiting groove, which can effectively improve the clamping effect of the composite film, ensure the stability of the composite film during tensile testing, and prevent loosening.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 This utility model provides a technical solution: a composite membrane quality testing device, including a frame 1 and a clamping assembly 3. The frame 1 has a lifting adjustment assembly 2 inside. The clamping assembly 3 includes a cylinder 305 and a first clamping frame 301 and a second clamping frame 302 distributed vertically. The second clamping frame 302 is fixedly connected to the output end of the lifting adjustment assembly 2. The first clamping frame 301 and the second clamping frame 302 are symmetrically provided with a first clamping plate 303 and a second clamping plate 304, which are movably connected. The output end of the cylinder 305 is fixedly connected to the outer wall of one of the first clamping plates 303. The two first clamping frames 301 are slidably connected by several vertically arranged guide rods 306. The second clamping frame... The top of 302 is horizontally provided with a guide groove 309 that matches the guide rod 306; the first clamping frame 301 and the second clamping frame 302 are arranged symmetrically from top to bottom; the first clamping plate 303 and the second clamping plate 304 are both L-shaped structures; the bottom center of the first clamping frame 301 is provided with a rotatably connected gear 307; the outer wall of the horizontal section of the first clamping plate 303 and the second clamping plate 304 is horizontally provided with racks 308 that mesh with the gears 307, and the two racks 308 are respectively located on both sides of the gears 307; the outer wall of the first clamping plate 303 is provided with a plurality of limiting members 312 on the side near the second clamping plate 304; the outer wall of the second clamping plate 304 is provided with limiting grooves that match the limiting members 312.

[0026] In one embodiment, the outer wall of the horizontal section of the first clamping plate 303 and the second clamping plate 304 is provided with a slider 310, and the outer wall of the first clamping frame 301 and the second clamping frame 302 is provided with a horizontal slide rail 311 that matches the slider 310. The slide rail 311 guides the slider 310, which can effectively improve the safety and stability of the sliding of the first clamping plate 303 and the second clamping plate 304.

[0027] In one embodiment, the limiting member 312 is designed as a hemispherical protrusion structure, and the limiting groove is designed as a hemispherical groove. When the first clamping plate 303 and the second clamping plate 304 clamp the composite film, the limiting member 312 with the hemispherical protrusion structure pushes the composite film into the hemispherical groove, which can effectively perform multi-point hemispherical limiting treatment on the surface of the composite film, and can effectively improve the clamping and fixing effect of the composite film. The distance between two adjacent limiting members 312 is equal to the outer diameter of the hemispherical protrusion, which limits the distribution of the limiting member 312 with the hemispherical protrusion structure, so that the limiting member 312 can completely press the composite film into the hemispherical groove, while ensuring the density of the distribution of the hemispherical limiting points, thereby further improving the limiting treatment effect of the composite film.

[0028] In one embodiment, the limiting member 312 is designed as a strip-shaped limiting strip, the limiting groove is a strip-shaped groove, and the cross-section of the limiting member 312 is a semi-circular structure. By designing the limiting member 312 as a strip-shaped limiting strip with a semi-circular cross-section, the strip-shaped limiting strip presses the composite film into the strip-shaped groove, which can realize multiple strip-shaped limiting and blocking treatment of the composite film and effectively improve the clamping stability of the composite film.

[0029] In one embodiment, the lifting adjustment assembly 2 includes a servo motor 203 and a vertically arranged ball screw 201 and guide rod 204. A screw nut 202 is movably fitted onto the outer wall of the ball screw 201. The output shaft of the servo motor 203 is fixedly connected to one end of the ball screw 201. A guide sleeve 205 is slidably fitted onto the outer wall of the guide rod 204. The second clamping frame 302 is fixedly connected to the screw nut 202 and the guide sleeve 205 via a support plate 313. When the lifting adjustment assembly 2 is working, the servo motor 203 drives the ball screw 201 to rotate, the ball screw 201 drives the screw nut 202 to move up and down, the guide sleeve 205 moves up and down with the screw nut 202, the guide rod 204 guides the guide sleeve 205, and the screw nut 202 drives the second clamping frame 302 to move up and down via the support plate 313, thereby performing a tensile test on the composite film.

[0030] The working principle of this utility model:

[0031] Refer to the instruction manual appendix Figures 1-6This utility model comprises a lifting adjustment assembly 2, a clamping assembly 3, a first clamping frame 301, a second clamping frame 302, a first clamping plate 303, a second clamping plate 304, and a cylinder 305. The frame 1 supports the lifting adjustment assembly 2. The clamping assembly 3 clamps and fixes the composite film. The first clamping frame 301 clamps and fixes the bottom of the composite film, and the second clamping frame 302 clamps and fixes the top of the composite film. The first clamping plate 303 and the second clamping plate 304 work together to clamp and fix the composite film. A guide groove 309 provides movement space for the guide rod 306 at the top of the second clamping frame 302, ensuring that the guide rod 306 moves along the guide... The groove 309 moves horizontally, while the second clamping frame 302 moves up and down along the guide rod 306. The extension and retraction of the cylinder 305 can drive a first clamping plate 303 to move horizontally back and forth. The first clamping plate 303 drives the first clamping plate 303 on the second clamping frame 302 to move horizontally back and forth through the guide rod 306, so that the first clamping frame 301 and the second clamping frame 302 can perform synchronous clamping or loosening operations, which can simultaneously realize the clamping and fixing of the upper and lower ends of the composite film, making the operation convenient and quick. After the composite film is clamped and fixed, the lifting adjustment component 2 is activated. The lifting adjustment component 2 drives the second clamping frame 302 to move upward, and the distance between the first clamping frame 301 and the second clamping frame 302 gradually increases, which can effectively realize the tensile testing of the composite film.

[0032] During the horizontal reciprocating motion of the first clamping plate 303, the rack 308 reciprocates horizontally along with it. The rack 308 drives the gear 307 to rotate, and the gear 307 drives another rack 308 to reciprocate horizontally. This rack 308 then drives the second clamping plate 304 to reciprocate horizontally. Since the two racks 308 move in opposite directions, the first and second clamping plates 303 and 304 move in opposite directions, allowing them to move synchronously to clamp or release the composite film, making the operation convenient and quick. When the first and second clamping plates 303 and 304 clamp the composite film, the limiting member 312 pushes the composite film into the limiting groove, effectively improving the clamping effect and ensuring the stability of the composite film during tensile testing, preventing loosening.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
