Description

Technical Field

[0001] This utility model relates to the technical field of PVB film testing equipment, and specifically discloses a PVB film penetration resistance testing device. Background Technology

[0002] PVB film (polyvinyl butyral film) is a thermoplastic resin film formed by the condensation of polyvinyl alcohol (PVA) and butyral under the action of an acidic catalyst. It has high transparency, strong adhesion and excellent mechanical properties, and is the core material of laminated glass. In the research and development and production of PVB film, it is often necessary to test its anti-penetration performance.

[0003] Chinese patent CN217561202U discloses a PVB film penetration resistance testing device, comprising a support, a barrier, and a pneumatic steel ball launching device. The support has an inverted conical shield at its top, with a slag discharge pipe at the center of its bottom. An annular barrier is located at the top of the shield, and a top cover is placed over the barrier. A radially arranged support frame is located at the bottom of the annular barrier, with a turntable at its center. A rotating shaft, which movably passes through the support frame, is located at the bottom of the turntable, and a locking nut is threaded onto the shaft corresponding to the bottom of the support frame. A clamp for vertically clamping the material to be tested is located at the top of the turntable. A pneumatic steel ball launching device capable of launching steel balls at the material to be tested is located on one side of the annular barrier. While this invention has a simple structure, is easy to use, and has a high safety factor, the device makes it difficult for the user to determine the angle of the material to be tested, which affects its practicality to some extent. Therefore, to solve this problem, this invention proposes a PVB film penetration resistance testing device. Utility Model Content

[0004] The present invention aims to provide a PVB film penetration resistance testing device, which facilitates users in determining the angle of the material to be tested, improves the efficiency of angle adjustment of the material to be tested, and enhances the practicality of the device.

[0005] This utility model is achieved through the following technical solution:

[0006] A PVB film penetration resistance testing device includes a protective mechanism. The protective mechanism includes a support, a collection hopper on the inner side of the support, an annular enclosure above the support, multiple buffer layers arranged in a circular array on the inner side of the annular enclosure, a pneumatic steel ball launching device on one side of the annular enclosure, a top cover connected to the upper end of the annular enclosure, a protective plate on one side of the upper end of the support, a limiting mechanism at the upper center of the support, the limiting mechanism including a base plate, two first connecting holes symmetrically arranged inside the base plate, multiple support rods arranged in a circular array on the outer side of the base plate, a mounting plate above the base plate, a rotating shaft connected to the lower center of the mounting plate, multiple second connecting holes arranged in a circular array on both sides of the mounting plate, two upright plates symmetrically connected above the mounting plate, and a limiting frame between the two upright plates.

[0007] As a further feature of the above solution, the upper inner side of the bracket is provided with a plurality of connecting plates arranged in a circular array, and a connecting shaft is provided above the connecting plates. The support rod is detachably connected to the connecting shaft, which facilitates the disassembly and assembly of the support plate and the limiting mechanism, so that the limiting mechanism can be removed before cleaning the collection hopper, thus facilitating the cleaning operation of the collection hopper.

[0008] As a further feature of the above solution, two limiting grooves are symmetrically arranged on the side of the bracket near the protective plate. The two sides of the protective plate are slidably connected to the two limiting grooves respectively, which can limit the position of the protective plate and facilitate the removal and placement of the protective plate.

[0009] As a further feature of the above solution, a discharge pipe is provided in the lower center of the collection hopper, and a bottom cover is detachably connected to the lower end of the discharge pipe to facilitate the discharge of residue from the collection hopper.

[0010] As a further feature of the above solution, the rotating shaft passes through the interior of the base plate and is rotatably connected to the base plate. The first connecting hole and the second connecting hole are threaded with screws, so that after the mounting plate is rotated to a suitable angle, the mounting plate and the components above it can be fixed with screws.

[0011] As a further feature of the above solution, a dust plug is provided inside the second connection hole to keep the second connection hole clean, prevent residue generated during the test from falling into the second connection hole, and reduce the workload of the user in cleaning the second connection hole.

[0012] As a further feature of the above solution, a connecting shaft is provided at the upper end of the upright plate, and the limiting frame includes a support plate. Both ends of the support plate are provided with clamping grooves. The upper end of the clamping groove is detachably connected to the connecting shaft. A plurality of threaded rods arranged in a linear array are threaded through one side of the clamping groove and threadedly connected to the threaded rods. One end of the threaded rod is connected to a clamping plate, which facilitates the disassembly and assembly of the limiting frame. Before testing, the limiting frame can be removed from between the two upright plates and taken out from the inside of the protective mechanism. The material to be tested can be fixed in the limiting frame using the clamping grooves and threaded rods, and then the connection between the clamping grooves and the connecting shaft can be restored, reducing the impact of the protective mechanism on the placement of the object to be tested.

[0013] In this utility model, the plane perpendicular to the mounting plate, where the line connecting the centers of the two first connecting holes lies, is perpendicular to the plane containing the axis of symmetry of the limiting frame and the two upright plates.

[0014] The present invention has the following beneficial effects during use:

[0015] The combination of the limiting groove and the protective plate can restrict the position of the protective plate and separate the launch port of the pneumatic steel ball launcher from the limiting frame before testing, so as to prevent the pneumatic steel ball launcher from starting when the material to be tested is placed due to incorrect operation, thus ensuring the safety of the user.

[0016] The combination of the first connecting hole and multiple second connecting holes in the limiting mechanism allows the user to determine the rotation angle of the mounting plate, the limiting mechanism above it, and the material to be tested based on the number of second connecting holes that are aligned with the first connecting hole before and after rotation, after the mounting plate stops rotating. This is then fixed with screws, improving the accuracy and efficiency of the angle adjustment of the material to be tested. Attached Figure Description

[0032] like Figure 1 and Figure 3 As shown, two limiting grooves 113 are symmetrically arranged on the side of the bracket 11 near the protective plate 12. The two sides of the protective plate 12 are slidably connected to the two limiting grooves 113 respectively, which can limit the position of the protective plate 12 and facilitate the removal and placement of the protective plate 12.

[0033] like Figure 3 and Figure 4 As shown, a discharge pipe 141 is provided in the lower middle part of the collection hopper 14, and a bottom cover 142 is detachably connected to the lower end of the discharge pipe 141 to facilitate the discharge of residues in the collection hopper 14.
