DETAILED DESCRIPTION
[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.
[0023] The utility model provides Figures 1 to 5 A dynamic balancing machine for a blade of a garbage disposer shown in the figure comprises a dynamic balancing machine body 1, a turntable 2 is arranged on the top of the dynamic balancing machine body 1, a blade 3 to be detected is installed on the top of the turntable 2, a panel 4 is arranged on the periphery of the turntable 2, a display 5 is arranged on the rear side of the panel 4, the display 5 is installed on the top of the dynamic balancing machine body 1, a baffle 6 is vertically arranged on one side of the panel 4, a cubic protective cover 7 is arranged on the side of the panel 4 away from the baffle 6, and the side of the protective cover 7 close to the baffle 6 and the bottom are both open designs, the protective cover 7 is slidably installed on the top of the dynamic balancing machine body 1, and the moving direction of the protective cover 7 is perpendicular to the baffle 6, and a protective component 8 is arranged on the top inner wall of the protective cover 7;
[0024] The protection assembly 8 includes a horizontally arranged retaining ring 81, and the width of the retaining ring 81 is greater than the gap between the inner side of the enclosure 4 and the outer side of the turntable 2, the bottom of the retaining ring 81 is flush with the top of the enclosure 4, and the outer diameter of the retaining ring 81 matches the outer diameter of the enclosure 4, and a plurality of fixing rods 82 are vertically fixedly connected to the top of the retaining ring 81, and a sleeve 83 is slidably sleeved on the top of the fixing rod 82, and the top of the sleeve 83 is fixedly connected to the top of the protective cover 7, and a shock-absorbing spring 84 is fixedly connected between the top of the fixing rod 82 and the top inner wall of the sleeve 83;
[0025] When the cutter disc 3 is dynamically balanced, the cutter disc 3 is first fixed to the turntable 2, and then the protective cover 7 is pulled to drive the retaining ring 81 to move toward the top of the cutter disc 3. When the protective cover 7 and the baffle plate 6 are attached together, the bottom of the retaining ring 81 is just located at the top of the enclosure 4 and is concentric with the enclosure 4. Then, the balancing machine body 1 is started to perform a dynamic balance test on the cutter disc 3, and the test result can be displayed on the display 5.
[0026] During the dynamic balancing test of the cutter disc 3, when the blade or movable block on the cutter disc 3 falls off, the blade or movable block can fly out along the cutting direction of the turntable 2 and contact the enclosure 4. Since the flying distance between the blade and the movable block is relatively close, when the blade or movable block contacts the enclosure 4, the enclosure 4 can quickly intercept the blade or movable block;
[0027] In addition, when the fallen blade or movable block contacts the bottom of the retaining ring 81 due to its upward flight angle, the retaining ring 81 compresses the shock-absorbing spring 84 due to the impact force, thereby converting the impact force of the blade or movable block on the retaining ring 81 into the elastic potential energy of the shock-absorbing spring 84, so that the blade and the movable block can stop as soon as possible and fall on the inside of the enclosure 4, thereby avoiding the fallen blade or movable block from damaging the protective cover 7 and facilitating the collection of the fallen blade or movable block after the detection is completed.
[0028] like Figure 3 and Figure 4As shown, a limiting ring 9 is slidably inserted into the inner side of the retaining ring 81, and the bottom of the limiting ring 9 is lower than the bottom of the retaining ring 81, and a positioning ring 10 is fixedly connected to the outer periphery of the top of the limiting ring 9, and a plurality of limiting rods 11 are vertically slidably inserted through the top of the positioning ring 10, and the bottom end of the limiting rod 11 is fixedly connected to the top of the retaining ring 81, and the top diameter of the limiting rod 11 is larger than its full body diameter, and protrusions 12 are symmetrically fixedly connected to the two sides of the limiting ring 9, and the bottom of the protrusion 12 is flush with the bottom of the limiting ring 9, the height of the protrusion 12 is equal to the distance from the bottom of the limiting ring 9 to the bottom of the retaining ring 81, and the thickness of the protrusion 12 gradually thickens from bottom to top toward the center of the limiting ring 9, and a receiving groove 13 is provided at the position of the bottom of the retaining ring 81 opposite to the protrusion 12, and the depth of the receiving groove 13 matches the height of the protrusion 12;
[0029] By providing a limiting ring 9, in the process of pulling the protective cover 7 to move it in the direction of the cutter disc 3, when the projection 12 on the side of the limiting ring 9 close to the baffle plate 6 contacts the top edge of the enclosure 4, as the protective cover 7 continues to move, the enclosure 4 can push the limiting ring 9 upward by the thrust on the inclined surface of the projection 12. When the bottom of the limiting ring 9 is flush with the top of the enclosure 4, the limiting ring 9 can move along the top of the enclosure 4 driven by the protective cover 7. When the projection 12 on the side of the limiting ring 9 away from the baffle plate 6 contacts the top of the enclosure 4, as the protective cover 7 continues to move, the limiting ring 9 can move away from the baffle plate 6. The protrusion 12 on the side away from the baffle plate 6 can be close to the top inner wall of the enclosure plate 4 to drive the limiting ring 9 to move slowly downward and finally be located inside the enclosure plate 4. At this time, the limiting ring 9 can cooperate with the baffle ring 81 and the enclosure plate 4 to form an annular storage cavity at the top edge position of the inner side of the enclosure plate 4, so that when the fallen blade or the movable block collides with the inner wall of the enclosure plate 4 and moves upward, the blade and the movable block can be intercepted by the storage cavity, thereby preventing the fallen blade and movable block from flying out of the inner area of the enclosure plate 4 due to collision, and at the same time, it is also convenient to collect the fallen blade and movable block after the detection is completed;
[0030] When the detection is completed, as the protective cover 7 is pulled away from the top of the cutter disc 3, the protrusion 12 on the side away from the baffle 6 can drive the limiting ring 9 to move upward under the squeezing effect of the inner wall of the enclosure 4. When the bottom of the limiting ring 9 is flush with the top of the enclosure 4, the limiting ring 9 can return to its original position driven by the protective cover 7.
[0031] like Figure 2 and Figure 3 As shown, a U-shaped first magnetic strip 14 is fixedly connected to one side of the baffle 6 close to the protective cover 7, and a U-shaped second magnetic strip 15 is fixedly connected to the inner side of the protective cover 7 opposite to the first magnetic strip 14. The magnetic poles of the second magnetic strip 15 and the first magnetic strip 14 are opposite, and the second magnetic strip 15 can contact the first magnetic strip 14.
[0032] By providing the first magnetic strip 14 and the second magnetic strip 15, when the protective cover 7 is closed, the protective cover 7 can be adsorbed together with the baffle 6 through the suction force between the first magnetic strip 14 and the second magnetic strip 15, thereby preventing the protective cover 7 from being separated from the baffle 6 due to vibration during the dynamic balancing test of the cutter disc 3, thereby ensuring the stability of the connection between the protective cover 7 and the baffle 6.
[0033] like Figure 1 and Figure 3 As shown, the side walls and the front and rear walls of the protective cover 7 are all hollowed out, and a first handle 16 is installed on the front side of the protective cover 7;
[0034] By designing the side wall of the protective cover 7 to be hollow, it is easy to observe the cutter disc 3 during the dynamic balancing test of the cutter disc 3, and thus to detect abnormal conditions in time; and by installing a first handle 16 on the protective cover 7, the protective cover 7 can be easily pulled.
[0035] like Figure 1 and Figure 5 As shown, the side of the enclosure 4 close to the baffle 6 is hinged to the top of the dynamic balancing machine body 1, and the side of the enclosure 4 away from the baffle 6 is fixedly connected to the second handle 17;
[0036] When the fallen blade or movable block is intercepted by the enclosure 4 and the retaining ring 81, the enclosure 4 can be pulled up by the second handle 17, so that the inner area of the enclosure 4 is exposed, thereby facilitating the collection of the fallen movable block or blade.
[0037] like Figures 3 to 5 As shown, the inner side of the enclosure 4 and the bottom of the retaining ring 81 are fixedly connected with a protective pad 18, and the protective pad 18 is made of wear-resistant rubber material;
[0038] By providing the protective pad 18, when the flying movable block or the blade hits the side wall of the enclosure 4 and the bottom of the retaining ring 81, the protective pad 18 can protect the enclosure 4 and the retaining ring 81, and also prevent the blade or the movable block from being damaged due to the impact.
[0039] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
