[0026] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides an injection molding waste filtering mechanism, comprising:

[0028] Installation box 1;

[0029] At least two filter plates 2, the installation box 1 is provided with a discharge port 13 corresponding to each filter plate 2, and one end of the filter plate 2 is rotatably disposed at the discharge port 13; and

[0030] The driving member is slidably disposed on one side of the installation box 1 and is slidably connected to each filter plate 2. When the driving member moves along the height direction of the installation box 1, it drives each filter plate 2 to rotate along its end as the axis.

[0031] In the embodiment of the utility model, the installation box 1 is placed in the bottom discharge area of ​​the crusher when in use. When the injection molding waste is crushed by the crusher, the crushed injection molding waste directly enters the installation box 1. Taking two filter plates 2 installed in the installation box 1 as an example, the filter holes of the upper filter plate 2 are larger than the filter holes of the lower filter plate 2. The injection molding waste can be filtered by the filter plate 2, and the larger injection molding waste is intercepted on the upper filter plate 2, and the injection molding waste that meets the standards is intercepted on the lower filter plate 2, and the powder passes through all the filter plates 2 and falls to the ground. The crushed injection molding waste can be screened multiple times without manual subsequent selection, saving time and manpower.

[0032] Secondly, with the cooperation of the driving member, each filter plate 2 can be driven to swing, so that the filter plate 2 is always in motion during filtering work, avoiding clogging of the filter holes by injection molding waste, ensuring its normal permeability, and allowing the filtering mechanism to always maintain a normal working state.

[0033] Based on the above scheme, Figure 2 and Figure 4As shown, the driving member includes a driving plate 8 slidably arranged on the side of the installation box 1, a driving block 11 slidably arranged on the side of the installation box 1 and connected to the driving plate 8, and a movable plate 7 hinged to the driving plate 8 and corresponding to each filter plate 2 respectively. The movable plate 7 is penetrated at one end of the filter plate 2. A mounting frame 6 is provided on the outside of the installation box 1. A driving wheel 10 is rotatably provided on the mounting frame 6. The driving wheel 10 is provided with a driving pin 9. The driving pin 9 is slidably engaged with the driving block 11.

[0034] Specifically, when each filter plate 2 is swung by the action of the driving member, the driving wheel 10 is rotated, so that the driving pin 9 on the driving wheel 10 performs a circular motion with the driving wheel 10 as the axis. Since the driving block 11 is limited and can only slide up and down, when the driving wheel 10 rotates, the driving pin 9 slides in the groove of the driving block 11, so that the driving block 11 reciprocates along the radial direction of the driving wheel 10, so that the driving block 11 drives the driving plate 8 connected thereto to reciprocate inside the installation box 1. Since the movable plate 7 is movably connected to the driving plate 8 and is slidably connected to the filter plate 2, when the driving plate 8 moves upward, the movable plate 7 drives the end of the filter plate 2 to move upward, and the movable plate 7 moves out of one end of the filter plate 2 to compensate for the end distance of the filter plate 2. Conversely, when the driving plate 8 moves downward, the movable plate 7 drives the end of the filter plate 2 to move downward, and the movable plate 7 moves into one end of the filter plate 2. When the up and down movements are repeated, the filter plate 2 is continuously swung with its end located at the discharge port 13 as the axis. In the selection of the driving source of the driving wheel 10, the motor can be installed on the mounting frame 6 for installing the driving wheel 10, or it can be connected to the crushing wheel through a belt.

[0035] Specifically, a limit block 12 is provided on the side of the driving plate 8, and the limit block 12 is slidably engaged with the inner side of the installation box 1, so as to limit the driving plate 8 so that the driving plate 8 can only slide along the direction of the limit block 12, avoiding forces in other directions and ensuring the connection strength between the driving plate 8 and the driving block 11.

[0036] Specifically, Figure 1 As shown, the mouth of the discharge port 13 is provided with a material guide port 3, and the outlet directions of the two material guide ports 3 are located on different sides of the same direction, which can better divert and collect injection molding waste of different sizes, providing convenience for subsequent processing.

[0037] Specifically, Figure 1 As shown, one end of the filter plate 2 close to the driving plate 8 is higher than the other end thereof, so that the filter plate 2 is tilted in the installation box 1. The filter plate 2 is initially tilted, and during the swinging operation of the filter plate 2, the injection molding waste intercepted on the filter plate 2 is more smoothly discharged from the discharge port 13, ensuring high efficiency of the filtering operation.

[0038] Specifically, Figure 3 As shown, a guide plate 5 is provided in the installation box 1 to guide the fallen injection molding waste so that it enters the filtering area of ​​the upper filter plate 2.

[0039] Specifically, Figure 1 As shown, a mounting portion 4 is provided on the top of the mounting box 1. The mounting portion 4 has a plurality of through holes, through which bolts can be inserted to fix the mounting box 1 to the bottom discharge area of ​​the pulverizer.

[0040] like Figure 5 As shown, the embodiment of the utility model also proposes a crusher, including a box body 14, and also includes the above-mentioned injection molding waste filtering mechanism. The specific structure of the filtering mechanism refers to the above-mentioned embodiment. Since the crusher adopts all the technical solutions of the above-mentioned embodiment, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiment, which will not be repeated here one by one.

[0041] In summary, by distributing filter plates 2 with different apertures up and down, injection molding waste of different shapes and sizes can be connected, and larger injection molding waste can be intercepted on the upper filter plate 2, and injection molding waste that meets the standards can be intercepted on the lower filter plate 2. The powder passes through all the filter plates 2 and falls to the ground, which is convenient for subsequent manual processing. With the support of the driving component, the driving plate 8 can be made to reciprocate to make each filter plate 2 swing, thereby ensuring the normal permeability of the filter plate 2 and ensuring the continuous filtering work.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
