[0002] PP board, also known as polypropylene plastic board, is a semi-crystalline material. It is harder than PE and has a higher melting point. Since homopolymer PP is very brittle when the temperature is above 0°C, many commercial PP materials are random copolymers with ethylene or clamp copolymers with a higher ethylene content. Before the PP board is shipped out of the factory, it is necessary to conduct strength performance testing on the PP board to test its performance.

DETAILED DESCRIPTION

[0021] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Combined with reference Figure 1-Figure 5The utility model provides a PP board strength detection device, including a machine frame 1, a loading plate 2 for placing the PP board is arranged at the inner bottom of the machine frame 1, a pair of light rods 3 are fixedly connected to the inner side of the machine frame 1, a slide seat 4 is slidably connected to the pair of light rods 3, a lifting device 5 is arranged on the slide seat 4, the lifting device 5 can use a hydraulic rod as a lifting power, the output end of the lifting device 5 movably passes through the slide seat 4 and is fixedly connected to a pressing plate 6, a pressure detection head 7 is fixedly connected to the bottom of the pressing plate 6, the lifting device 5 can drive the pressure detection head 7 to frequently contact with the surface of the PP board through the pressing plate 6, the pressure detection head 7 can be built-in with a pressure sensor to record test data, and can communicate with an external terminal A wireless transmission connection is realized, which can facilitate the aggregation of test data for the traceability of multi-point test information of the PP board. A support plate 8 is fixedly connected to the pressure plate 6, and a pair of elastic support members 9 are arranged on the support plate 8. A rack 10 is arranged on the pair of elastic support members 9. In the present application, the rack 10 can adopt an incomplete rack structure, and a track guide plate 11 is fixedly connected to the side of the rack 10. A passive power-assisting structure 13 that is in active contact with the track guide plate 11 is arranged on the slide 4. A bracket 14 is fixedly connected to the slide 4, and a linear transmission component 15 that cooperates with the transmission connection of the rack 10 is arranged on the bracket 14. The linear transmission component 15 is used to drive the slide 4 to slide on the light rod 3.

[0023] The elastic support member 9 includes a telescopic rod 91 fixedly connected to the side of the support plate 8 and a traction spring 92 sleeved on the telescopic rod 91. The end of the telescopic rod 91 facing away from the support plate 8 is fixedly connected to the rack 10. Both ends of the traction spring 92 are fixedly connected to the opposite surfaces of the support plate 8 and the rack 10. The two ends of the traction spring 92 can be fixed by a spring seat. The traction spring 92 can be used to elastically pull the rack 10 moving away from the support plate 8 to facilitate the resetting of the position of the rack 10. The telescopic rod 91 is a sleeve structure of the prior art. In this way, when the rack 10 moves, the telescopic rod 91 can provide a linear telescopic effect for the rack 10.

[0024] Both ends of the track guide plate 11 are provided with sliding slopes 12. The setting of the sliding slopes 12 can facilitate the passive power-assisting structure 13 to slide on the track guide plate 11 through the sliding slopes 12. By utilizing the different distances between the end and middle positions of the track guide plate 11, the passive power-assisting structure 13 can adapt to the position change of the pushing rack 10 through the track guide plate 11.

[0025] The passive assist structure 13 includes a limit frame 131 fixedly connected to the side of the slide seat 4, an abutment plate 132 arranged on the inner side of the limit frame 131 and a torsion spring shaft 133 arranged on the limit frame 131. The abutment plate 132 is rotatably connected to the limit frame 131 via the torsion spring shaft 133.

[0026] The contact plate 132 is in active contact with the track guide plate 11 .

[0027] Specifically, when the pressure detection head 7 performs strength detection on the PP plate, after the pressure detection head 7 detects a point, the lifting device 5 can perform a telescopic return movement. At this time, the support plate 8 drives the rack 10 to move up through the elastic support member 9, and the track guide plate 11 on the rack 10 can contact the abutment plate 132. The abutment plate 132 is limited by the angle of the limit frame 131, so that the abutment plate 132 can abut horizontally on the track guide plate 11, so that the telescopic rod 91 can be adaptively extended, and the traction spring 92 is in a stretched state. At this time, the rack 10 contacts the linear transmission assembly 15 until the abutment plate 132 is located at the sliding slope 12 at the other end of the track guide plate 11. At this time, the rebound force of the traction spring 92 can cause the telescopic rod 91 to contract, so that the rack 10 is relatively close to the support plate 8.

[0028] It is worth noting that in the present application, the elastic force of the torsion spring of the torsion spring shaft 133 is greater than the elastic force of the traction spring 92. The advantage of such a design is that it can accelerate the deformation speed of the torsion spring shaft 133 when the torsion spring shaft 133 and the traction spring 92 deform synchronously.

[0029] The linear transmission assembly 15 includes a transmission shaft 151 rotatably connected to the bracket 14, a pair of gears 152 fixedly connected to both ends of the transmission shaft 151, and a rack 153 meshingly connected to one of the gears 152, the rack 153 is fixedly connected to the inner side of the frame 1, and the other gear 152 is meshingly contacted with the rack 10.

[0030] Specifically, when the telescopic rod 91 is adaptively extended and the traction spring 92 is in a stretched state, the rack 10 is meshed with one of the gears 152, and the rack 10 continues to move upward, so that the other gear 152 can roll on the path of the rack 2 153, so that the transmission shaft 151 can drive the slide 4 to slide on the light rod 3 through the bracket 14, so that the position of the pressure detection head 7 can be adjusted to the next station;

[0031] When it is necessary to control the pressure detection head 7 to squeeze the PP plate, because the abutment plate 132 is located at the bottom end of the track guide plate 11, and because the elastic force of the torsion spring of the torsion spring shaft 133 is greater than the elastic force of the traction spring 92, the downward movement of the track guide plate 11 can drive the abutment plate 132 to fold and rotate downward based on the connection of the torsion spring shaft 133. By temporarily storing the abutment plate 132 in the limit frame 131, the lateral position of the downward movement of the rack 10 will not be changed, and the rack 10 will not be in transmission contact with the gear 152, thereby stabilizing the vertical position of the pressure detection head 7 at this time. Similarly, when the lifting device 5 continues to move back, the pressure detection head 7 can continue to move to the next detection position. Therefore, compared with manual strength testing of the PP plate, the present application can achieve the effect of saving time and effort, and the entire equipment only involves one power equipment, which is low in cost and can meet the quality inspection cost requirements.
