Description

Technical Field

[0001] This invention relates to the field of glass production technology, specifically to a mechanical testing device for laminated glass. Background Technology

[0002] Glass is widely used in buildings for wind insulation and light transmission, and is a mixture. There are also colored glasses, which exhibit color due to the incorporation of certain metal oxides or salts, and tempered glass, produced through physical or chemical methods. During glass production, to ensure durability, it is often necessary to test the hardness of the glass. However, existing testing devices rarely provide statistical data on glass hardness. Therefore, a solution is needed to address this technical problem.

[0003] As disclosed in the patent document CN211013878U, this device, through the use of a first slide bar, a second slide bar, and a slider, allows the clamping plate to be moved to any position, thereby throwing the weight downward from any position. At the same time, due to the use of a pressure sensor, the impact value on the glass placed by the device can be obtained in detail. Furthermore, due to the use of a plastic film and a protective plate, when the glass breaks, the ejected fragments can be prevented from causing accidents to the workers, thus improving the safety of the device.

[0004] However, when the aforementioned device is used to test laminated glass, it only performs impact testing on the front side of the laminated glass and does not test the back side, making the method of testing the hardness of laminated glass incomplete. In addition, the existing testing methods all use impact beads to impact the laminated glass vertically, but in real-world environments, hail will impact the laminated glass at an angle, making vertical impact alone ineffective for testing laminated glass. Furthermore, the existing structure for adjusting the impact position of the impact beads is relatively complex and inconvenient for manual maintenance. Moreover, the glass fragments generated during the impact test can easily affect subsequent laminated glass testing. Summary of the Invention

[0005] The technical problem that this solution addresses is:

[0006] (1) How to set up a flipping mechanism, adjust the flipping angle of the control frame by extending and retracting the cylinder, and cooperate with the collision bead to facilitate the hardness detection of the two sides of the laminated glass, thereby improving the detection efficiency of the laminated glass. At the same time, since the laminated glass is in an inclined state, the collision bead is released vertically, so that the collision bead can perform tilt collision detection on the laminated glass, further improving the detection efficiency of the laminated glass.

[0007] (2) How to set up a cleaning mechanism, tilt the control frame, block one of the recycling pipes with a sealing plate, and then suck air into the corresponding absorption hole through the other recycling pipe. When the laminated glass is tested for collision, the glass fragments generated fall onto the control frame and are easily and quickly absorbed through the absorption hole, so as to avoid the glass fragments affecting the subsequent laminated glass test.

[0008] (3) How to set up a detection mechanism, and drive the placement tool to move slightly on the guide rail by rotating the L-shaped rod, so as to play the function of placing collision beads at multiple positions on the laminated glass. At the same time, since the structure is relatively simple, it will be convenient for manual maintenance and upkeep in the later stage, reducing the cost of use.

[0009] The objective of this invention can be achieved through the following technical solution: a mechanical testing device for laminated glass, comprising a base and a mounting frame fixedly installed on the top of the base. The top of the base is also provided with a flipping mechanism for adjusting the angle of the laminated glass. Two baffles for guiding impact beads are symmetrically arranged on both sides of the flipping mechanism. Both baffles are fixedly connected to the mounting frame. A through groove is opened on the top of the mounting frame. A testing mechanism for testing the impact hardness of laminated glass is movably arranged inside the through groove.

[0010] The flipping mechanism includes a rotating seat fixedly connected to the base. A control frame is rotatably mounted on the top of the rotating seat. The inner wall of the control frame has a storage slot for placing laminated glass. An anti-slip pad for limiting the laminated glass is provided on the inner wall of the storage slot. A control unit for driving the laminated glass to flip is provided on the front of the control frame, and a limit plate is fixedly installed on the bottom of the control frame. Two conveying units for conducting collision beads are symmetrically arranged on both sides of the bottom of the rotating seat. A cleaning mechanism for absorbing glass shards is provided on the back of the control frame.

[0011] A further technical improvement of the present invention is that: both of the baffles are provided with shock-absorbing layers on the sides facing the flipping mechanism; the shock-absorbing layers buffer the collision beads that bounce off the baffles, preventing the collision beads from colliding with the laminated glass again, and at the same time guide the collision beads into the storage box in conjunction with the guide groove; two storage boxes for storing collision beads are also symmetrically arranged on both sides of the flipping mechanism, and the bottom of the storage boxes is slidably connected to the base.

[0012] A further technical improvement of the present invention is that: the control unit includes a horizontally arranged cylinder, the cylinder is fixedly connected to one of the baffles and a fixed plate, the fixed plate is fixedly connected to the base, and a sliding groove is also provided on the front of the control frame, and the output end of the cylinder is movably connected to the sliding groove through a lever.

[0013] A further technical improvement of the present invention is that: the conveying unit includes a guide seat fixedly connected to the base, the guide seat having a guide groove on the side facing the corresponding storage box, the bottom of the guide groove corresponding to the input end of the storage box; the laminated glass is placed in the storage slot, and the laminated glass is fixed and limited by the anti-slip pad to prevent it from shaking and affecting the detection efficiency of the laminated glass hardness; the extension end of the cylinder is used to extend and retract to adjust the flip angle of the control frame, and the collision beads released by the feeding fixture facilitate the hardness detection of both sides of the laminated glass, improving the detection efficiency of the laminated glass; at the same time, since the laminated glass is in an inclined state, the collision beads are released vertically, so that the collision beads can perform inclined collision detection on the laminated glass, further improving the detection efficiency of the laminated glass.

[0014] A further technical improvement of the present invention is that a limiting groove is provided on the side of the guide seat facing the limiting plate, and the size of the limiting groove corresponds to the size of the limiting plate.

[0015] A further technical improvement of the present invention is that: the cleaning mechanism includes an air suction pipe connected to the input end of an external air suction device; two recovery pipes are symmetrically connected to the top of the air suction pipe; two absorption holes for absorbing glass shards are symmetrically opened on the back of the control frame; the input end of the absorption hole is connected to the inner wall of the control frame; and sealing plates are symmetrically arranged on both sides of the back of the control frame; when the extended end of the cylinder is extended to half its length, the control frame is in a vertical state, at which time the input ends of the two recovery pipes correspond to the positions of the two absorption holes, respectively, and the external air suction device is activated to clean the residue on the control frame. The system absorbs excess dust to prevent scratching the laminated glass during placement. When the cylinder's extended end reaches its longest or shortest position, the control frame is tilted. One of the recovery pipes is blocked by a sealing plate, while the other recovery pipe draws air into the corresponding absorption hole. Blocking one recovery pipe increases the airflow velocity in the other. When glass fragments generated during laminated glass collision testing fall onto the control frame, they are quickly and efficiently absorbed through the absorption hole, preventing the glass fragments from affecting subsequent laminated glass testing.

[0016] A further technical improvement of the present invention is that: the detection mechanism includes a guide rail fixedly installed on the inner wall of the through groove, and a dispensing fixture for releasing collision beads is slidably arranged on the guide rail. The dispensing fixture is prior art. An L-shaped rod is rotatably arranged on the mounting frame below the dispensing fixture via a pin. One end of the L-shaped rod is movably connected to the dispensing fixture, and the pin is positioned close to the dispensing fixture.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] In use, this invention uses anti-slip pads to fix and limit the laminated glass, preventing it from shaking and affecting the efficiency of hardness testing. The extension end of the cylinder is used to adjust the flip angle of the control frame. Combined with the impact beads released by the tooling, it is convenient to test the hardness of both sides of the laminated glass, thus improving the testing efficiency. At the same time, since the laminated glass is in an inclined state, the impact beads are released vertically, allowing the impact beads to perform tilted impact testing on the laminated glass, further improving the testing efficiency.

[0019] In use, when the cylinder's extended end is half its length, the control frame is in a vertical position. At this time, the input ends of the two recovery pipes correspond to the positions of the two absorption holes, respectively. The external suction device is activated to absorb residual dust on the control frame, preventing dust from scratching the laminated glass when it is placed. When the cylinder's extended end is at its longest or shortest position, the control frame is in an inclined position. One of the recovery pipes is blocked by a sealing plate, and air is drawn into the corresponding absorption hole through the other recovery pipe. Because one recovery pipe is blocked, the airflow velocity in the other recovery pipe is increased. When glass fragments generated during the laminated glass collision test fall onto the control frame, they are easily and quickly absorbed through the absorption holes, preventing the glass fragments from affecting the subsequent laminated glass testing.

[0020] When in use, the L-shaped rod is rotated by manually operating the handle, which causes the dispensing fixture to move slightly on the guide rail, thus dispensing collision beads at multiple positions on the laminated glass. At the same time, due to the simple structure, it is easy to maintain and repair manually in the later stage, reducing the cost of use. Attached Figure Description

[0029] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-6 As shown, the laminated glass mechanical testing device includes a base 4 and a mounting frame 7 fixedly installed on the top of the base 4. The top of the base 4 is also provided with a flipping mechanism 2 for adjusting the angle of the laminated glass. Two baffles 6 for guiding collision beads are symmetrically arranged on both sides of the flipping mechanism 2. Both baffles 6 are fixedly connected to the mounting frame 7, and both baffles 6 are provided with a shock-absorbing layer on the side facing the flipping mechanism 2. The shock-absorbing layer buffers the collision beads that bounce off the baffles 6, preventing the collision beads from colliding with the laminated glass again. At the same time, it works with the guide groove 2031 to guide the collision beads into the storage box 5, which facilitates the recycling of the collision beads, reduces the manual process of collecting the collision beads, and avoids the loss of the collision beads. Two storage boxes 5 for collecting collision beads are also symmetrically arranged on both sides of the flipping mechanism 2. The bottom of the storage box 5 is slidably connected to the base 4. The top of the mounting frame 7 is provided with a through groove 8. The inside of the through groove 8 is a testing mechanism 1 for testing the impact hardness of the laminated glass.

[0031] Please see Figures 1-3As shown, the aforementioned flipping mechanism 2 includes a rotating seat 205 fixedly connected to the base 4. A control frame 206 is rotatably mounted on the top of the rotating seat 205. The inner wall of the control frame 206 is provided with a storage groove 207 for placing laminated glass. An anti-slip pad for limiting the laminated glass is provided on the inner wall of the storage groove 207. A control unit for driving the laminated glass to flip is provided on the front of the control frame 206, and a limit plate 204 is fixedly installed on the bottom of the control frame 206. A cleaning mechanism 9 for absorbing glass shards is provided on the back of the control frame 206. When rotating, the limit plate 204 contacts two guide seats 2033 respectively, so that the limit plate 204 limits the position of the control frame 206, and works with the cylinder 202 to prevent the laminated glass from flipping excessively. Two conveying units 203 for transmitting collision beads are symmetrically arranged on both sides of the bottom of the rotating seat 205.

[0032] Please see Figure 1 and Figure 2 As shown, the aforementioned control unit includes a horizontally arranged cylinder 202. The cylinder 202 is fixedly inserted through one of the baffle plates 6 and is fixedly connected to a fixing plate 3. The fixing plate 3 is fixedly connected to the base 4. The fixing plate 3 and the corresponding baffle plate 6 limit the cylinder 202 to prevent it from tilting when it provides thrust to the control frame 206. The front of the control frame 206 is also provided with a sliding groove 201. The output end of the cylinder 202 is movably connected to the sliding groove 201 through a lever.

[0033] Please see Figure 2 and Figure 5 As shown, the aforementioned conveying unit 203 includes a guide seat 2033 fixedly connected to the base 4. The guide seat 2033 has a guide groove 2031 on the side facing the corresponding storage box 5. The bottom of the guide groove 2031 corresponds to the input end of the storage box 5. The guide seat 2033 has a limit groove 2032 on the side facing the limit plate 204. The size of the limit groove 2032 corresponds to the size of the limit plate 204. The laminated glass is placed in the storage tank 207, and the laminated glass is fixed and limited by the anti-slip pad to prevent it from shaking and affecting the detection efficiency of the laminated glass hardness. The extension end of the cylinder 202 is extended and retracted to adjust the flip angle of the control frame 206. The collision beads released by the feeding fixture 104 facilitate the hardness detection of both sides of the laminated glass, improving the detection efficiency of the laminated glass. At the same time, since the laminated glass is in an inclined state, the collision beads are released vertically, so that the collision beads can perform tilt collision detection on the laminated glass, further improving the detection efficiency of the laminated glass.

[0034] Please see Figure 3 and Figure 4As shown, the cleaning mechanism 9 described above includes a suction pipe 903 connected to the input end of an external suction device. Two recovery pipes 902 are symmetrically connected to the top of the suction pipe 903. Two absorption holes 901 for absorbing glass shards are symmetrically opened on the back of the control frame 206. The input end of the absorption hole 901 is connected to the inner wall of the control frame 206. Sealing plates 904 are symmetrically arranged on both sides of the back of the control frame 206. When the extended end of the cylinder 202 extends to half its length, the control frame 206 is in a vertical state. At this time, the input ends of the two recovery pipes 902 correspond to the positions of the two absorption holes 901, respectively. The external suction device is then activated to clean the remaining glass shards on the control frame 206. Dust is absorbed to prevent it from scratching the laminated glass during placement. When the cylinder 202 is extended to its longest or shortest position, the control frame 206 is tilted. One of the recovery pipes 902 is blocked by the sealing plate 904, and air is drawn into the corresponding absorption hole 901 through the other recovery pipe 902. Because one recovery pipe 902 is blocked, the airflow velocity in the other recovery pipe 902 is increased. When glass fragments generated during the laminated glass collision test fall onto the control frame 206, they are quickly and efficiently absorbed through the absorption hole 901, preventing the glass fragments from affecting the subsequent laminated glass testing.

[0035] Please see Figure 1 and Figure 6 As shown, the aforementioned testing mechanism 1 includes a guide rail 101 fixedly installed on the inner wall of the through groove 8. A dispensing fixture 104 for releasing collision beads is slidably disposed on the guide rail 101. The dispensing fixture 104 stores a sufficient number of collision beads. The dispensing fixture 104 is existing technology. An L-shaped rod 102 is rotatably disposed on the mounting frame 7 below the dispensing fixture 104 via a pin 103. One end of the L-shaped rod 102 is movably connected to the dispensing fixture 104. The pin 103 is positioned close to the dispensing fixture 104, which facilitates manual fine-tuning of the position of the dispensing fixture 104 and avoids excessive adjustment affecting the testing effect on the laminated glass.

[0036] Please see Figure 6 As shown, a handle is fixedly installed at the end of the L-shaped rod 102 away from the dispensing fixture 104. By manually operating the handle, the L-shaped rod 102 is rotated, thereby causing the dispensing fixture 104 to move slightly on the guide rail 101, which serves to dispense collision beads at multiple positions on the laminated glass. At the same time, since the structure is relatively simple, it is convenient for manual maintenance and upkeep, reducing the cost of use.

[0037] Working Principle: In use, the laminated glass is first placed in the storage tank 207. Anti-slip pads are used to fix and limit the laminated glass, preventing it from shaking and affecting the efficiency of hardness testing. Then, the extension of the cylinder 202 is used to adjust the tilting angle of the control frame 206. This, combined with the impact beads released by the feeding fixture 104, facilitates hardness testing on both sides of the laminated glass, improving testing efficiency. Simultaneously, because the laminated glass is tilted, the impact beads are released vertically, allowing the impact beads to tilt the laminated glass. Collision detection further improves the detection efficiency of laminated glass. After impacting the laminated glass, the impact beads will bounce towards the baffle plate 6. The shock-absorbing layer buffers the impact beads that bounce onto the baffle plate 6, preventing the impact beads from colliding with the laminated glass again. At the same time, the guide groove 2031 guides the impact beads into the storage box 5, which facilitates the recycling of the impact beads, reduces the manual collection process, and avoids the loss of impact beads. By manually operating the handle, the L-shaped rod 102 is rotated, thereby driving the delivery fixture 104 on the guide rail 101. Slight movement occurs on the upper part, which serves to place collision beads at multiple locations on the laminated glass. Simultaneously, due to its relatively simple structure, it facilitates manual maintenance and reduces operating costs. When the extended end of cylinder 202 reaches half its length, the control frame 206 is in a vertical position. At this time, the input ends of the two recovery pipes 902 correspond to the positions of the two absorption holes 901, activating the external suction device to absorb residual dust on the control frame 206, preventing dust from scratching the laminated glass during placement. When cylinder 202 extends... When the outlet is extended to its longest or shortest state, the control frame 206 is tilted. One of the recovery pipes 902 is blocked by the sealing plate 904, and air is drawn into the corresponding absorption hole 901 through the other recovery pipe 902. Because one of the recovery pipes 902 is blocked, the airflow velocity in the other recovery pipe 902 is increased. When glass fragments generated during the laminated glass collision detection fall onto the control frame 206, they are easily and quickly absorbed through the absorption hole 901, preventing the glass fragments from affecting the subsequent laminated glass detection.
