[0003] The chemical name of amino molding plastic is polyurethane resin, which is a polymer compound generated by the reaction of isocyanate and polyol. In the production process of amino molding plastic products, the amino molding plastic raw materials need to be crushed and then hot-melt molded to obtain the finished amino molding plastic products. Since the amino molding plastic has different particle sizes after crushing, the plastic products made of amino molding plastic particles of different sizes will affect the finished products during hot-melt molding. Therefore, after crushing, it is necessary to screen the amino molding plastic particles of different particle sizes, classify them, and combine the amino molding plastic particles of the same particle size for hot-melt molding, so that high-quality amino molding plastic products can be obtained.
[0004] During operation of the existing screening device, the mesh holes on the screen plate are often clogged due to the different sizes of amino molding plastic particles, which affects the screening efficiency and quality. Therefore, a screening device that can prevent the screen plate from being clogged is needed. Utility Model Content

[0006] The purpose of the present application is to provide an amino molding plastic particle screening device, which provides a connecting pipe between two sieve plates. When the vibration motor vibrates the outer shell, the elastic ball in the connecting pipe is driven to bounce back and forth between the two sieve plates, and reciprocatingly strikes the sieve plates at both ends of the connecting pipe, so that the amino molding plastic particles stuck or stuck between the sieve holes are thrown up and dropped. In this way, the amino molding plastic particles blocked on the sieve plate can be vibrated away, thereby solving the problem of the amino molding plastic particles blocking the sieve plate.

[0017] Compared with the prior art, the beneficial effects of this application are:

[0022] The present application is further described below in conjunction with the accompanying drawings and embodiments. Example
[0023] An amino molding compound particle screening device, such as Figure 1-2 As shown, it includes: an outer shell 1, a sieve plate 9, a connecting plate 6, a support frame 8, a spring, and a vibration motor 5. The outer shell 1 is a rectangular parallelepiped. The bottom surface of the outer shell 1 is provided with a right-angled triangle protrusion 4. The vibration motor 5 is fixedly connected to one side of the short side of the right-angled triangle protrusion 4. A connecting plate 6 is provided on the side of the outer shell 1. The connecting plate 6 and the support frame 8 are connected by a spring. Two sieve plates 9 are provided in the outer shell 1. The two sieve plates 9 are parallel to each other. The angle between the sieve plate 9 and the bottom surface of the outer shell 1 is fifteen degrees. A connecting pipe 10 is provided between the two sieve plates 9. The connecting pipe 10 is provided with an elastic ball 11, and each connecting pipe 10 has at least one elastic ball 11.
[0024] After the vibration motor 5 is turned on, it drives the shell 1 to vibrate as a whole, and the shell 1 is made to reciprocate back and forth on the support frame 8 through the spring, so that the screen plate 9 can be driven to move with the shell 1. Since there is a certain angle between the screen plate 9 and the ground of the shell 1, under the combined effect of the exciting force of the vibration motor 5 and the self-gravity of the material, the amino molding plastic particles are thrown up and jumped on the screen plate 9 for screening.
[0025] like Figure 2 As shown, the inclined surface of the right-angled triangle protrusion 4 is fixedly connected to the bottom of the housing 1 , and the right-angled triangle protrusion 4 is located in the middle of the bottom surface of the housing 1 .
[0026] like Figure 1 As shown, there are four connecting plates 6 , which are respectively located on both sides of the housing 1 , and are respectively connected to the support frame 8 via springs.
[0027] like Figure 1As shown, a rubber protective sleeve 7 is provided on the outside of the spring, and the two ends of the rubber protective sleeve 7 are respectively connected to the connecting plate 6 and the supporting frame 8. The rubber protective sleeve 7 encloses the spring in the rubber protective sleeve 7. The rubber protective sleeve 7 plays a role in dustproof and anti-collision for the spring, protecting the spring from external damage.
[0028] like Figure 2 As shown, the connecting tube 10 is perpendicular to the bottom plate of the housing 1 , and the position where the connecting tube 10 contacts the sieve plate 9 is in a closed state, so as to prevent amino molding plastic particles on the sieve plate 9 from falling into the connecting tube 10 and affecting the rebound work of the elastic ball 11 .
[0029] like Figure 2 As shown, the diameter of the elastic ball 11 is smaller than the diameter of the connecting tube 10 , and the elastic ball 11 is a silica gel bouncing ball with good elasticity.
[0030] There are six connecting tubes 10 , which are evenly distributed between the two sieve plates 9 , so that the elastic balls 11 in the connecting tubes 10 bounce back and forth in the connecting tubes 10 .
[0031] like Figure 2 As shown, the mesh openings of the two screen plates 9 decrease from top to bottom.
[0032] like Figure 2 As shown, a guide plate 12 is provided at the bottom of the housing 1 , and the guide plate 12 discharges the amino molding compound particles leaking out of the sieve plate 9 below.
[0033] like Figure 1 As shown, a feed port 2 is provided at the top of the shell 1, and the feed port 2 is located on one side of the sieve plate 9. A discharge port 3 is provided on the side of the sieve plate 9 away from the feed port 2. There are three discharge ports 3, and the three discharge ports 3 correspond to two sieve plates 9 and the guide plate 12 respectively.
[0034] During the working process, the amino molding plastic particles are fed into the feed port 2, enter the outer shell 1, and fall on the uppermost sieve plate 9, and the vibration motor 5 is turned on. The vibration motor 5 has an inclination angle with the sieve plate 9 in the vertical direction through the right-angled triangle protrusion 4 on the outer shell 1. Under the combined effect of the exciting force and the self-weight of the material, the amino molding plastic particles are thrown up and jumped on the sieve plate 9, thereby realizing the screening of the amino molding plastic particles, and through the inclination of the sieve plate 9, the amino molding plastic particles move from the feed port 2 toward the discharge port 3 during the vibration process, and are finally discharged through the discharge port 3. Amino molding plastic particles of different particle sizes are obtained by screening with two layers of sieve plates 9, and finally amino molding plastic particles of different particle sizes are discharged from different discharge ports 3.
[0035] During this process, the connecting tube 10 is evenly distributed between the two sieve plates 9, and the elastic balls 11 in the connecting tube 10 also bounce back and forth under the action of the exciting force, reciprocatingly hitting the sieve plates 9 at both ends of the connecting tube 10, so that the amino molding plastic particles stuck or stuck between the sieve holes are thrown up and dropped, so that the amino molding plastic particles blocked on the sieve plate 9 can be vibrated away, and the amino molding plastic particles can be sent to the discharge port 3 through the exciting force of the vibration motor 5, so that the problem of the amino molding plastic particles blocking the sieve plate 9 can be solved.
[0036] The constraint of the connecting pipe 10 can prevent the elastic ball 11 from moving around between the two sieve plates 9 and can also prevent the elastic ball 11 from leaking out of the discharge.
[0037] Although the above describes the specific implementation methods of the present application in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present application. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present application, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present application.
