[0002] Sprue material mainly refers to the plastic residue remaining in the runner system that fills the mold cavity during injection molding, including the solidified portions of the main runner, branch runners, and gate after cooling. In addition, trial mold scrap, debugging waste, and defective products from production are also categorized as sprue material. Because the raw material of sprue material is the same as that of the injection-molded product, it can be recycled and used as raw material.

[0003] When recycling sprue scrap, it needs to be crushed for convenient use. Traditionally, soft and hard sprue scrap is recycled and crushed separately, which is not only energy-intensive but also inconvenient to operate.

[0004] Therefore, this application proposes an injection molding machine edge sprue material recycling crusher, which can simultaneously crush soft and hard edge sprue materials to improve the convenience of recycling. Utility Model Content

[0039] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0040] Please see Figures 1 to 5 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0041] like Figures 1-2 As shown, this utility model provides an injection molding machine sprue material recycling and crushing machine, including a support mechanism 1 for supporting the entire device. A crushing mechanism 2 is mounted on the support mechanism 1, with through holes at both the top and bottom. The upper through hole is the feed hole, and the lower through hole is the discharge hole. Sprue material enters the crushing mechanism 2 through the upper through hole, and the crushed slag is discharged through the lower through hole. A feeding box 3 is mounted above the crushing mechanism 2. The upper part of the feeding box 3 is connected to the injection molding machine waste discharge port, and the lower part of the feeding box 3 is connected to the interior of the crushing mechanism 2. During the injection molding process, the sprue material generated falls into the feeding box 3 and is then guided into the crushing mechanism 2 for crushing, achieving integrated crushing without the need for material separation, thus saving time and improving efficiency.

[0042] A drive motor 4 is installed above the support mechanism 1. The output shaft of the drive motor 4 extends into the interior of the crushing mechanism 2 to drive the blades inside the crushing mechanism 2 to rotate, for crushing the side sprue material.

[0043] Above the support mechanism 1, a human-machine interface device 6 is also installed. The human-machine interface device 6 is a power distribution box with control buttons. The human-machine interface device 6 is connected to an external power source. After being transferred through the human-machine interface device 6, the power source is connected to the drive motor 4, thereby enabling the human-machine interface device 6 to control the start, stop, and speed of the drive motor 4.

[0044] like Figure 2As shown, in some embodiments, the crushing mechanism 2 of this utility model includes a crushing box 21, and a pyramid-shaped material drop box 22 is arranged below the crushing box 21. Multiple sets of rotating crushing blades 24 are arranged inside the crushing box 21. The rotating crushing blades 24 are connected to the output shaft of the drive motor 4, so that the drive motor 4 can drive the rotating crushing blades 24 to rotate, and the shearing force generated by the drive motor 4 can cut and crush the edge sprue material.

[0045] like Figure 2 As shown, in some embodiments, the bottom cross-section of the pyramid-shaped material discharge box 22 of this invention is smaller than the top cross-section, thus making the cross-section of the pyramid-shaped material discharge box 22 an inverted pyramid shape. When the side discharge material is crushed, the discharge position can be more concentrated, which facilitates the recycling or centralized transportation of the debris.

[0046] like Figure 4 and Figure 5 As shown, in some embodiments, the rotary crusher 24 of this invention includes a drive roller 241, which is connected to the output shaft of a drive motor 4, thereby enabling the drive roller 241 to be driven to rotate by the drive motor 4. A plurality of equally spaced crushing blades 242 are arranged on the outer surface of the drive roller 241. When the drive roller 241 rotates, the crushing blades 242 rotate accordingly, generating cutting and shearing forces to cut and crush the edge sprue material. Gripping teeth 243 are intermittently arranged between the crushing blades 242, with the outer surface of the gripping teeth 243 protruding from the outer surface of the crushing blades 242. When the gripping teeth 243 rotate with the drive roller 241, they grip the edge sprue material and convey it between the two crushing blades 242. This prevents the edge sprue material from being too light or too large and rotating between the two crushing blades 242, thus avoiding proper cutting and crushing.

[0047] like Figure 3 As shown in some embodiments, the inner wall of the crushing box 21 of this invention is symmetrically provided with multiple scraper teeth 23. All scraper teeth 23 are parallel to the crushing blades 242, and the scraper teeth 23 are located between two adjacent crushing blades 242. The ends of the scraper teeth 23 abut against the outer surface of the transmission roller 241, thereby filling the gap between the crushing blades 242, thus preventing the edge slag from falling from the gap between the crushing blades 242 and the inner wall of the crushing box 21, and improving the efficiency of crushing edge slag.

[0048] like Figure 1 and Figure 2As shown, in some embodiments, the feed box 3 of this utility model includes a conveying pipe 31. The conveying pipe 31 is inclined to form a channel for conveying the sprue material, allowing the sprue material to fall into the interior of the crushing box 21 under the action of gravity. A feed hopper 32 is provided at the top of the conveying pipe 31. The feed hopper 32 is a bucket-shaped body, with its upper opening cross-section larger than its lower opening cross-section, so that the sprue material discharged from the injection molding machine can enter the interior of the conveying pipe 31 more effectively. A connecting seat 33 is provided at the bottom of the conveying pipe 31, and the bottom of the connecting seat 33 is detachably connected to the top of the crushing box 21. When maintenance is required, the interior of the crushing box 21 can be cleaned and maintained by disassembling the conveying pipe 31, improving the convenience of maintenance.

[0049] like Figure 1 and Figure 2 As shown, in some embodiments, the bottom of the drive motor 4 of this utility model is provided with a blowing device 5, which is a blower or a hair dryer. The air outlet of the blowing device 5 faces the bottom of the pyramid-shaped material box 22. When waste recycling is required, the blower 5 can be used in conjunction with the pipe to blow the crushed edge sprue scrap into the circulation port of the injection molding machine for use as raw material.

[0050] The blower 5 is connected to the human-machine interface 6, and the start / stop and blowing intensity of the blower 5 can be controlled through the human-machine interface 6.

[0051] like Figure 1 and Figure 2 As shown, in some embodiments, the support mechanism 1 of this utility model includes two support beams 11, and each support beam 11 is provided with a crushing device support frame 12 at its top. The two crushing device support frames 12 are respectively connected to the crushing box 21 from both sides, thereby providing positioning support for the crushing box 21. A sideways U-shaped support frame 13 is provided at the top of the support beams 11. The U-shaped support frame 13 supports the human-machine interaction device 6, thereby facilitating the assembly and disassembly of the human-machine interaction device 6.

[0052] like Figure 1 and Figure 2 As shown, in some embodiments, each support beam 11 of this invention is provided with rollers 14 at both ends of its bottom. The rollers 14 are omnidirectional wheels. The rollers 14 facilitate the transfer of the entire device, improving ease of use.

[0053] like Figure 1 As shown, in some embodiments, a connecting frame is provided between the two support beams 11 of this utility model for connection, so that the two support beams 11 become a whole. The drive motor 4 and the blower 5 are both mounted on the connecting frame, so that the drive motor 4 and the blower 5 can be layered vertically and do not interfere with each other.

[0054] In summary, the injection molding machine sprue material recycling and crushing machine of this utility model recycles the sprue material discharged from the injection molding machine by setting up a feeding box 3. The recycled sprue material falls into the crushing mechanism 2 for crushing, turning the sprue material into slag. The slag is discharged from the bottom of the crushing mechanism 2 for collection and reuse, achieving the effect of eliminating the need to separate hard and soft materials and saving crushing time and electricity.

[0055] This utility model achieves automatic feeding by setting a blowing device 5 between the support mechanisms 1, blowing air into the opening of the pyramid-shaped material box 22 through the blowing device 5, thereby driving the crushed raw material residue to the circulation port of the injection molding machine for reuse, thus achieving the effect of saving labor.

[0056] This invention improves crushing efficiency by providing crushing blades 242 on the outer surface of the transmission roller 241, which cut and crush the edge sprue material through rotation. At the same time, gripping teeth 243 are provided on the outer surface of the transmission roller 241 to grip the edge sprue material, so as to avoid the edge sprue material being too light or too large to be crushed by the crushing blades 242.

[0057] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0058] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
