Description

Technical Field

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

[0002] Plastic products are a general term for daily necessities and industrial products made primarily from plastic. Plastic is a material that can be molded into a certain shape under certain temperature and pressure conditions and maintains its shape at room temperature. Plastic rulers are used in many fields. However, before plastic rulers are put on the market, their toughness needs to be tested to ensure that the toughness of the plastic rulers leaving the factory meets the standards. A search revealed a plastic product testing device disclosed in Chinese patent CN221765101U, which includes a housing. The top of the housing is equipped with a testing component, and the bottom left and right sides of the housing are equipped with a pair of mounting brackets. The mounting brackets are rotatably connected to a second threaded rod, and the top of the second threaded rod extends to the top of the mounting bracket. The outer side of the second threaded rod is threadedly connected to multiple clamping plates, and a clamping block is set above the clamping plates. This utility model uses the rotation of the second threaded rod to drive the multiple clamping plates upward through the threads. The upward-moving clamping plates cooperate with the clamping blocks to clamp and fix the plastic rulers placed on the clamping plates, fixing multiple plastic rulers at once, making it more convenient to use.

[0003] However, in actual use, this method can only detect the deformation of the plastic product by pressing down the test head and folding it at the center. This testing method is relatively simple and does not test the torsional strength that the plastic product can withstand. Utility Model Content

[0004] To address the issue that existing devices have limited functionality in detecting plastic products, this invention provides a plastic product testing device.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A plastic product testing device includes a testing box. Fixed discs are installed on both sides of the inner wall of the testing box. A torsion seat is provided between the two fixed discs in the testing box. A rotating disc is rotatably connected inside the torsion seat. Clamping mechanisms are installed on the adjacent sides of the rotating disc and the fixed discs. The torsion seat includes a housing. A worm and a worm wheel are rotatably connected to both sides of the inner wall of the housing. The worm and the worm wheel mesh with each other. The interior of the worm wheel is fitted to one end of the rotating disc. A motor is installed on the outer wall of the housing, and the output end of the motor is drivenly connected to one end of the worm.

[0007] Furthermore, a testing assembly is slidably connected inside the testing box. The testing assembly includes a lifting plate, and limit rods are connected to both sides of the top surface of the lifting plate. Holes are opened on the top surface of the testing box that intersect with the two limit rods.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the test component can achieve precise adjustment of the test position by sliding the lifting plate up and down along the limiting rod. The interlocking fit of the holes on the top of the limiting rod detection box can restrict the movement direction of the lifting plate, prevent it from deviating or shaking during the lifting process, and ensure the smooth operation of the test component.

[0009] Furthermore, pressure rods are installed on both sides of the bottom surface of the lifting plate, and the two pressure rods are respectively located between the two sets of clamping mechanisms.

[0010] The advantage of adopting the above-mentioned further solution is that vertical pressure can be applied to plastic products during testing to simulate the pressure conditions in actual use.

[0011] Furthermore, a hydraulic cylinder is installed on the top surface of the testing box, and the output end of the hydraulic cylinder extends into the interior of the testing box and is connected to the top surface of the lifting plate.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the hydraulic cylinder drives the lifting plate through the output end, and the hydraulic drive can provide more stable and accurate pressure control, and can withstand a larger load, thus meeting the pressure testing requirements of plastic products of different specifications.

[0013] Furthermore, the clamping mechanism includes a frame, with partitions equidistantly installed inside the frame, and a knob threadedly connected to the outer wall of the partition, with one end of the knob penetrating through the partition.

[0014] The advantage of adopting the above-mentioned further solution is that by rotating the knob, one end of it extends inside the partition until the knob clamps and fixes the plastic product.

[0015] Furthermore, the rotating disk includes a shaft, which is fitted inside the worm gear, and a first disk body and a second disk body are respectively installed at both ends of the shaft.

[0016] The beneficial effect of adopting the above-mentioned further solution is that it ensures stable power transmission, driving the first and second discs to rotate synchronously. The dual-disc design increases the installation space of the clamping mechanism, allowing multiple samples to be fixed simultaneously for batch testing, thus improving testing efficiency.

[0017] Furthermore, the outer wall of the testing box is hinged with a door, and a handle is installed on the outer wall of the door.

[0018] The advantages of adopting the above-mentioned further solutions are that it makes it easier for operators to place and take out plastic products; the handle provides a point of force application, making the operation of opening and closing the cabinet door more convenient and effortless.

[0019] Furthermore, the door includes a door panel, and an observation window is embedded in one side of the door panel.

[0020] The advantage of adopting the above-mentioned further solution is that the observation window allows operators to observe the detection process and sample status inside the detection chamber in real time without opening the chamber door, thus avoiding frequent opening of the chamber and affecting the stability of the detection environment.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This plastic product testing device, through the coordinated use of a fixed plate, a torsion seat, a rotating plate, and a clamping mechanism, enables the device to test the torsional strength and folding strength of plastic products. The torsion seat is driven by a motor to rotate a worm gear, which in turn meshes with a worm wheel, causing the rotating plate to rotate. This causes the clamping mechanisms on both sides to rotate accordingly. Combined with the clamping mechanism on the fixed plate, one side of the plastic product is clamped and fixed. Thus, by fixing one side and torsion on the other, the torsional strength of the plastic product is tested. Furthermore, by ensuring that the clamping mechanisms at different positions remain horizontally stable, the folding strength of the plastic product within the clamping mechanism is easily tested.

[0030] Please see Figures 1-5 This utility model provides a technical solution: a plastic product testing device, including a testing box 1, with fixed plates 9 installed on both sides of the inner wall of the testing box 1, and a torsion seat 6 located between the two fixed plates 9. A rotating disk 7 is rotatably connected inside the torsion seat 6, and clamping mechanisms 8 are installed on the adjacent sides of the rotating disk 7 and the fixed plates 9. The torsion seat 6 includes a housing 601, with a worm gear 602 and a worm wheel 603 rotatably connected on both sides of the inner wall of the housing 601. The worm gear 602 and the worm wheel 603 mesh with each other, and the interior of the worm wheel 603 is fitted onto one end of the rotating disk 7. The outer wall of the housing 601... A motor 604 is installed, and the output end of the motor 604 is connected to one end of the worm gear 602. The torsion seat 6 drives the worm gear 602 to rotate through the motor 604. The worm gear 602 meshes with the worm wheel 603, which drives the rotating disk 7 to rotate, causing the clamping mechanisms 8 on both sides to rotate accordingly. Together with the clamping mechanism 8 on the fixed disk 9, one side of the plastic product is clamped and fixed. In this way, by fixing one side and twisting the other side, the torsional strength of the plastic product can be tested. Furthermore, by keeping the clamping mechanisms 8 in different positions horizontal and stable, it is convenient to test the folding strength of the plastic product in the clamping mechanism 8.

[0031] 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.

[0032] In one embodiment of this utility model, a test assembly 3 is slidably connected inside the test box 1. The test assembly 3 includes a lifting plate 301, with limit rods 302 connected to both sides of the top surface of the lifting plate 301. The top surface of the test box 1 has holes that intersect with the two limit rods 302. The test assembly 3 slides up and down along the limit rods 302 via the lifting plate 301, achieving precise adjustment of the test position. The interlocking cooperation between the limit rods 302 and the holes on the top surface of the test box 1 restricts the movement direction of the lifting plate 301, preventing it from shifting or shaking during lifting and ensuring the smooth operation of the test assembly 3.

[0033] As an embodiment of this utility model, pressure rods 303 are installed on both sides of the bottom surface of the lifting plate 301. The two pressure rods 303 are located between the two sets of clamping mechanisms 8, which can apply vertical pressure to the plastic product during testing to simulate the pressure conditions in actual use.

[0034] As an embodiment of this utility model, a hydraulic cylinder 4 is further installed on the top surface of the test box 1. The output end of the hydraulic cylinder 4 extends into the interior of the test box 1 and is connected to the top surface of the lifting plate 301. The hydraulic cylinder 4 drives the lifting plate 301 through its output end. The hydraulic drive can provide more stable and accurate pressure control and can withstand a larger load, thus meeting the pressure testing requirements of plastic products of different specifications.

[0035] As an embodiment of this utility model, the clamping mechanism 8 further includes a frame 801, with partitions 802 installed at equal intervals inside the frame 801. A knob 803 is threadedly connected to the outer wall of the partition 802, and one end of the knob 803 passes through the partition 802. By rotating the knob 803, one end of it extends inside the partition 802 until the knob 803 clamps and fixes the plastic product.

[0036] In one embodiment of this utility model, the rotating disk 7 further includes a shaft 701, which is fitted inside the worm gear 603. A first disk 702 and a second disk 703 are respectively installed at both ends of the shaft 701 to ensure stable power transmission and drive the first disk 702 and the second disk 703 to rotate synchronously. The dual-disc design increases the installation space of the clamping mechanism 8, allowing multiple samples to be fixed simultaneously for batch testing, thus improving testing efficiency.

[0037] As an embodiment of this utility model, the outer wall of the testing box 1 is hinged with a door 2, and a handle 5 is installed on the outer wall of the door 2 to facilitate the operator to place and take out plastic products; the handle 5 provides a force application point, making the opening and closing of the door 2 more convenient and effortless.

[0038] As an embodiment of this utility model, the door 2 further includes a door panel 201, and an observation window 202 is embedded on one side of the door panel 201. The observation window 202 allows the operator to observe the detection process and sample status inside the detection chamber 1 in real time without opening the door 2, thus avoiding frequent opening of the chamber and affecting the stability of the detection environment.

[0039] Specifically, the working principle of this plastic product testing device is as follows: In use, first open the door using the handle 5 of the door 2, place the plastic product between the clamping mechanism 8 of the fixed plate 9 and the rotating plate 7, and rotate the knob 803 of the clamping mechanism 8 to clamp and fix the plastic product through the partition 802. After closing the door, start the motor 604 on the outer wall of the torsion seat 6 housing 601. The motor 604 drives the worm gear 602 to rotate, and the worm gear 602 meshes with the worm wheel 603, driving the rotating plate 7, which is fitted with the worm wheel 603, to rotate. This causes the clamping mechanism 8 on one side of the rotating plate 7 to twist accordingly, cooperating with the clamping mechanism 8 fixed on the fixed plate 9 to complete the test of the torsional strength of the plastic product. When it is necessary to test the folding strength, the clamping mechanisms 8 in different positions are adjusted to maintain horizontal stability. Meanwhile, the output end of the hydraulic cylinder 4 on the top surface of the testing chamber 1 drives the lifting plate 301 to slide up and down along the limit rod 302, precisely adjusting the position of the testing component 3. The pressure rod 303 on the bottom surface of the lifting plate 301 moves between the two sets of clamping mechanisms 8. The hydraulic cylinder 4 uses hydraulic drive to apply stable and precise vertical pressure to the pressure rod 303, simulating the pressure conditions of plastic products in actual use, thereby realizing the pressure resistance test. During the test, the operator can observe the situation inside the chamber in real time through the observation window 202 on the door panel 201 of the chamber door 2 to ensure the smooth progress of the test.
