Description

Technical Field

[0001] The utility model belongs to the technical field of plastic particle detection, and in particular relates to a plastic particle strength testing device. Background Art

[0002] Plastic particles refer to granular plastics, which are generally divided into more than 200 types and subdivided into thousands of types. Common plastic particles include general-purpose plastics, engineering plastics, and special plastics; general-purpose plastics: polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, polyurethane, etc.; engineering plastics: nylon, polytetrafluoroethylene, polyoxymethylene, polycarbonate silicone, etc.

[0003] In the Chinese patent with publication number CN217845933U, a plastic particle strength testing device is mentioned. Before testing the plastic particles, the staff of the plastic particle strength testing device places the plastic particles on the carrier plate through the auxiliary plate, and by evenly arranging a plurality of placement grooves on the carrier plate, each plastic particle can be evenly placed on the carrier plate, and because the placement grooves limit the bottom of the plastic particles, when the plastic particles are pressed, no large displacement occurs, and then the carrier plate is placed on the workbench, and the plastic particles are pressed by the stamping mechanism to perform a strength test. The first slide groove and the sliding block are adapted to make the stamping plate more stable during the up and down sliding process, further effectively avoiding the problem of uneven pressure on plastic particles in different directions due to the instability of the stamping process during the stamping of the plastic particles on the carrier plate by the stamping plate, and effectively ensuring the accuracy of the plastic particle strength test;

[0004] When the device of this patent is actually used, the staff needs to place the plastic particles on the auxiliary plate, and then shake the auxiliary plate to make the plastic particles fall into the limiting grooves. However, during the shaking process, the plastic particles are easy to fall off the auxiliary plate, and when the staff pours the plastic particles on the auxiliary plate, it cannot be guaranteed that the number of poured plastic particles is exactly the same as the number of limiting grooves, and the excess plastic particles will remain on the auxiliary plate. When the auxiliary plate is removed from the carrier plate, the excess plastic particles are easy to fall from the limiting grooves, which requires the staff to collect the fallen plastic particles one by one, which is more troublesome to use.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-Figure 6 As shown, a plastic particle strength testing device comprises a base 1, a loading plate 2 is placed at the center position of the top of the base 1, a plurality of placement grooves 21 for placing plastic particles are provided on the top of the loading plate 2, and the plastic particles are placed separately to ensure that each plastic particle is evenly compressed, and an auxiliary plate 3 is movably installed on the top of the loading plate 2, through which the plastic particles can be evenly placed in the placement groove 21, and a plurality of limiting grooves 5 are provided inside the auxiliary plate 3, and the plastic particles are sprinkled on the auxiliary plate 3, and the auxiliary plate 3 is shaken to make the plastic particles fall into the limiting groove 5, and an anti-fall plate 6 is movably connected to the bottom of the auxiliary plate 3, after the plastic particles are placed in the placement groove 21, the anti-fall plate 6 is inserted into the bottom of the auxiliary plate 3, and the bottom of the auxiliary plate 3 can be closed to prevent excess plastic particles on the auxiliary plate 3 from falling from the limiting groove 5, and there is no need for staff to collect the plastic particles one by one, which is convenient for staff to use.

[0026] Specifically, multiple placement grooves 21 are distributed in a rectangular array, multiple limiting grooves 5 correspond to the multiple placement grooves 21 respectively, and the inner wall edge of the limiting groove 5 is provided with a transition arc surface 51, and the transition arc surface 51 can accelerate the plastic particles to enter the limiting groove 5. The plastic particles entering the limiting groove 5 can fall into the placement groove 21 along the limiting groove 5, so that the plastic particles can be evenly distributed in the multiple placement grooves 21.

[0027] More specifically, both sides of the bottom of the auxiliary plate 3 are fixedly connected with slide rails 7 for the anti-fall plate 6 to slide in. After the plastic particles fall into the placement groove 21, the anti-fall plate 6 is inserted between the two slide rails 7, and the anti-fall plate 6 can block the limit groove 5.

[0028] More specifically, a handle 61 is provided at one end of the anti-fall plate 6, and a chamfered surface 62 is provided at the other end of the anti-fall plate 6. When plastic particles have entered the placement groove 21 and excess plastic particles have entered the limiting groove 5, the anti-fall plate 6 is inserted into the slide rail 7, and the chamfered surface 62 can be located between the two plastic particles. The chamfered surface 62 facilitates the lifting of excess plastic particles in the limiting groove 5 and closes the limiting groove 5 to prevent excess plastic particles from falling from the limiting groove 5. The handle 61 can facilitate the staff to pull the anti-fall plate 6.

[0029] Furthermore, a shielding plate 4 is fixedly installed on the top edge of the auxiliary plate 3. The shielding plate 4 is arranged in a U-shape. When the auxiliary plate 3 is shaken, the shielding plate 4 can prevent the plastic particles on the auxiliary plate 3 from falling from the edge of the auxiliary plate 3.

[0030] Specifically, mounting grooves 9 are provided at the four corners of the top of the carrier plate 2, and guide blocks 8 are fixedly connected to the four corners of the bottom of the auxiliary plate 3. The four guide blocks 8 correspond to the four mounting grooves 9 respectively. The guide blocks 8 and the mounting grooves 9 can guide the installation of the auxiliary plate 3. The guide blocks 8 are inserted into the mounting grooves 9, and the auxiliary plate 3 can be installed on the carrier plate 2. At this time, the limiting groove 5 and the placement groove 21 coincide with each other, and the plastic particles on the auxiliary plate 3 can enter the placement groove 21 along the limiting groove 5.

[0031] More specifically, a bracket 10 is fixedly installed on the top of the base 1, and the bracket 10 is arranged outside the carrier plate 2. A stamping mechanism 11 is arranged on the bracket 10, and the stamping mechanism 11 includes a hydraulic cylinder, and a pressure plate is fixedly connected to the output end of the hydraulic cylinder. Driving the hydraulic cylinder can drive the pressure plate to press down, and the pressure plate can squeeze the plastic particles on the carrier plate 2, so that the strength of the plastic particles can be tested.

[0032] Working principle: When in use, the staff installs the auxiliary plate 3 on the carrier plate 2, and then sprinkles the plastic particles on the auxiliary plate 3, shakes the auxiliary plate 3 to make the plastic particles fall into the limiting groove 5, and the shielding plate 4 can prevent the plastic particles from falling. The plastic particles falling into the limiting groove 5 can fall into the placement groove 21 along the limiting groove 5. When plastic particles fall into each placement groove 21, the anti-fall plate 6 is inserted into the slide rail 7, and the chamfered surface 62 can lift up the excess plastic particles in the limiting groove 5 and close the limiting groove 5. Then the auxiliary plate 3 is removed from the carrier plate 2. Due to the blocking of the anti-fall plate 6, the excess plastic particles on the auxiliary plate 3 will not fall from the limiting groove 5, and the plastic particles on the auxiliary plate 3 can be directly poured to the designated location for unified collection. There is no need for the staff to collect the plastic particles one by one, which is convenient for the staff to use.
