DETAILED DESCRIPTION

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

[0025] Example 1: Please refer to Figure 1-Figure 3 and Figure 6The automatic material dividing and cutting machine for an injection molding machine shown in the figure includes a cutting machine body 1, which is used to cut plastic workpieces. A four-channel material dividing mechanism 2 is arranged on the inner side of the cutting machine body 1; the four-channel material dividing mechanism 2 also includes: a main blanking box body 3 installed on the inner side of the bracket of the cutting machine body 1, a first partition plate 4 is fixed on the inner side of the main blanking box body 3 to divide it into two, second partition plates 5 are fixed on both sides of the bottom of the first partition plate 4, one end of the second partition plate 5 is fixed to the inner wall of the main blanking box body 3, a first movable plate 6 is arranged above the top of the first partition plate 4, and a movable plate 6 is arranged above the top of the second partition plate 5. The second movable plate 7, the first partition plate 4 and the second partition plate 5 evenly divide the space inside and near the bottom of the main blanking box body 3 into four parts, and a blanking channel 8 is fixedly installed at the bottom end of the main blanking box body 3 and at the corresponding positions of the four parts. A first driving member 9 is installed at one end of the first movable plate 6, and a second driving member 10 is installed at one end of the second movable plate 7; a plurality of brush rollers 11 are installed on the inner side of the blanking channel 8, and the plurality of brush rollers 11 are evenly distributed and are used to clean the debris on the surface of the cut plastic workpiece, and a third driving member 12 is installed on the outer side of the blanking channel 8.

[0026] In the present solution, the space in the main blanking box 3 is evenly divided into four independent parts through the ingenious layout of the first partition 4 and the second partition 5, and each part is provided with an independent material discharge channel 8. Such a layout not only ensures that the cut plastic workpieces can flow into different channels in an orderly manner, but also improves the accuracy of material separation; secondly, through the driving parts installed on the first movable plate 6 and the second movable plate 7, the opening and closing of the movable plates can be flexibly controlled to realize the diversion of plastic workpieces of different materials. This design enables the cutting machine to automatically adjust the material separation strategy according to different processing requirements, thereby improving work efficiency; in addition, the multiple brush rollers 11 arranged in the material discharge channel 8 can clean the debris on the surface of the cut plastic workpiece through the drive of the third driving part 12, which not only improves the quality of the workpiece, but also reduces the work intensity of subsequent processing; in summary, the present invention realizes automatic material separation and debris cleaning of cut plastic workpieces by improving the existing injection molding machine cutting machine, improves work efficiency and product quality, reduces manual operation costs, and has significant technical progress and practical value.

[0027] For further information, see Figure 4The first driving member 9 includes a first cylinder 13, a first rack 14, a first gear 15, a first rotating shaft 16 and a first limiting plate 17. These components work together to realize the function of driving the first movable plate 6 to rotate. The first cylinder 13 is fixed to the outer wall of one side of the main blanking box body 3 through the first limiting plate 17. It is firmly fixed to the outer wall of one side of the main blanking box body 3 through the first limiting plate 17. The telescopic end of the first cylinder 13 is fixed with the first rack 14 by bolts, which enables the rack to move with the extension and contraction of the cylinder. The first movable plate 6 A first rotating shaft 16 is fixed at both ends, and a first gear 15 is fixedly sleeved on the outer side of one of the first rotating shafts 16. The first gear 15 is meshingly connected with the first rack 14. When the first rack 14 moves with the extension and retraction of the cylinder, it will be meshingly connected with the first gear 15. This meshing connection enables the linear motion of the rack to be converted into the rotational motion of the gear. The first rotating shaft 16 is rotatably installed with the top of the main blanking box body 3 through a bearing seat. This installation method ensures both the flexibility of the rotating shaft and its stability during operation.

[0028] Through the design of the above-mentioned first driving member 9, the first driving member 9 can provide continuous and stable power for the rotation of the first movable plate 6. It is worth mentioning that the design of this driving mechanism is not only compact in structure and easy to operate, but also has high transmission efficiency and accuracy. In practical applications, it can effectively drive the first movable plate 6 to rotate according to a predetermined trajectory, thereby automatically opening and closing the top two sides of the main blanking box 3.

[0029] For further information, see Figure 5 The second driving member 10 includes a second cylinder 18, a second rack 19, a second gear 20, a second rotating shaft 21 and a second limiting plate 22. These components work together to realize the function of driving the second movable plate 7 to rotate. The second cylinder 18 is fixed to the outer wall of one side of the main blanking box body 3 through the second limiting plate 22. The telescopic end of the second cylinder 18 is fixed with a second rack 19 by bolts, which enables the rack to move with the extension and contraction of the cylinder. Second rotating shafts 21 are fixed at both ends of the second movable plate 7, and the outer side of one of the second rotating shafts 21 is fixedly sleeved with a second gear 20. The second gear 20 and the second rack 19 are meshed and connected. When the second rack 19 moves with the extension and contraction of the cylinder, it will be meshed and connected with the second gear 20. This meshing connection enables the linear motion of the rack to be converted into the rotational motion of the gear. The two second rotating shafts 21 are rotatably installed with the main blanking box body 3 and the first partition plate 4 through bearings respectively. This installation method not only ensures the flexibility of the rotating shaft, but also ensures its stability during operation.

[0030] Through the design of the above-mentioned second driving member 10, the second moving member can provide continuous and stable power for the rotation of the second movable plate 7. It is worth mentioning that the design of this driving mechanism is not only compact in structure and easy to operate, but also has high transmission efficiency and accuracy. In practical applications, it can effectively drive the second movable plate 7 to rotate according to a predetermined trajectory, thereby automatically opening and closing the bottom of the main blanking box 3.

[0031] For further information, see Figure 4 and Figure 5 Baffles 32 are fixed at both ends of the first movable plate 6 and the second movable plate 7, and the first movable plate 6 and the second movable plate 7 are both inclined. This design is not only beautiful, but also allows the plastic workpiece to slide naturally along the inclined surface when it falls onto the movable plate until it reaches a predetermined position, which greatly reduces the steps of manual adjustment of the workpiece and ensures that the workpiece can remain stable during the sliding process. The inclined baffle 32 forms a natural "fence", which allows the workpiece to always remain within the range of the movable plate during the sliding process, greatly reducing the risk of the workpiece falling or scattering.

[0032] For further information, see Figure 1 A discharge port 33 is provided at the bottom of the material discharge channel 8, and a material receiving trolley 34 is provided directly below each discharge port 33. The material receiving trolley 34 is exquisitely designed, and a material receiving trough compatible with the discharge port 33 is provided on the top to ensure that the plastic workpiece can fall into it accurately. In addition, rollers and tracks are installed at the bottom of the material receiving trolley 34, so that the trolley can be easily moved, which is convenient for switching between different material discharge channels 8, thereby improving production efficiency; at the same time, the material receiving trolley 34 also has an automatic counting function, which detects the number of workpieces falling into the material receiving trough in real time through a built-in sensor, so that the operator can grasp the production progress and the number of workpieces conveniently.

[0033] Example 2: Please refer to Figure 6 and Figure 7 This embodiment further explains the first embodiment, and the difference lies in that the plastic workpiece can be cleaned.

[0034] Specifically, there are multiple brush rollers 11 on the inner side of the unloading channel 8, and the multiple brush rollers 11 are evenly distributed and are used to clean the debris on the surface of the cut plastic workpiece. A third driving member 12 is installed on the outer side of the unloading channel 8; the third driving member 12 includes a driving motor 23, a driving pulley 24, a synchronous belt 25, a driven pulley 26 and a third rotating shaft 27. A support plate 28 is fixed to one side of the driving motor 23, and the support plate 28 is fixed to the outer wall of the unloading channel 8. The driving pulley 24 is fixedly sleeved on the output end of the driving motor 23, and the driven pulley 26 is fixedly sleeved on the outer side of the third rotating shaft 27. The third rotating shaft 27 is fixed to the end of the brush roller 11 and is rotatably connected to the unloading channel 8 through a bearing. A plurality of driven pulleys 26 are provided, and the plurality of driven pulleys 26 and the driving pulley 24 are connected through a synchronous belt 25 for transmission.

[0035] It is worth mentioning that in industrial production, especially in the field of plastic processing, after cutting the plastic workpiece, there are often debris left on the surface of the workpiece. If these debris are not cleaned in time, it will not only affect the appearance quality of the workpiece, but also may cause obstacles to subsequent processing. Therefore, by designing multiple evenly distributed brush rollers 11, when the plastic workpiece passes through the unloading channel 8, the rotation of the brush roller 11 can effectively clean the debris on the surface of the workpiece. The material of the brush roller 11 is wear-resistant and soft, which can not only ensure the cleaning effect but also avoid damage to the workpiece surface.

[0036] Principle of rotation of the brush roller 11: In order to drive these brush rollers 11 to rotate, the driving motor 23 is the power source of the entire driving system. It is fixedly connected to the outer wall of the unloading channel 8 through the support plate 28, ensuring the stability of the entire driving system. The driving pulley 24 is fixedly sleeved on the output end of the driving motor 23. When the driving motor 23 is started, the driving pulley 24 rotates accordingly, and the driven pulley 26 is fixedly sleeved on the outer side of the third rotating shaft 27, and the third rotating shaft 27 is fixedly connected to the end of the brush roller 11. In this way, when the driving pulley 24 rotates, through the transmission action of the synchronous belt 25, it can drive multiple driven pulleys 26 and the third rotating shaft 27 to rotate, thereby driving the brush roller 11 to rotate.

[0037] It is worth mentioning that the number of driven pulleys 26 matches the number of brush rollers 11, ensuring that each brush roller 11 can be stably driven. In addition, the design of the synchronous belt 25 makes the entire transmission system more stable and reliable, reducing the problem of inconsistent rotation speed of the brush roller 11 caused by transmission error.

[0038] In summary, the designed multiple brush rollers 11 and the third driving member 12 can further improve the quality of the cut workpieces, reduce the scrap rate, save costs for the enterprise, and improve production efficiency.

[0039] At the same time, the plurality of brush rollers 11 are symmetrically distributed in pairs, and a distance greater than the thickness of the plastic workpiece is left between two relatively distributed brush rollers 11, so that the cut plastic workpiece can smoothly enter between the two relatively arranged brush rollers 11 for cleaning.

[0040] Example 3: Please refer to Figure 6 This embodiment further illustrates other embodiments, and the difference lies in that the feed channel 8 is optimized.

[0041] Specifically, the inner wall of the material discharge channel 8 is fixed with a first inclined plate 29, a second inclined plate 30 and a third inclined plate 31, which are arranged in sequence from top to bottom, and the bottom end of the third inclined plate 31 extends to the entrance between two relatively distributed brush rollers 11. In the internal design of the material discharge channel 8, we have specially considered the optimization of the material falling path. To this end, we have fixed the first inclined plate 29, the second inclined plate 30 and the third inclined plate 31 on the inner wall of the channel, which are arranged in sequence from top to bottom, forming a gradient guiding structure, which helps the material to gradually change direction during the falling process and finally reach the predetermined position. Among them, the design of the third inclined plate 31 is particularly important, and its bottom end extends to the entrance between two relatively distributed brush rollers 11. Such a design not only allows the material to enter the processing area of ​​the brush roller 11 more smoothly, but also effectively prevents the material from being offset or scattered during the falling process.

[0042] In summary, the presence of these three inclined plates greatly improves the flow state of the plastic workpiece in the material discharge channel 8, and they can effectively change the falling path of the cut material, making it more stable and orderly. In addition, the design of the inclined plate also has a certain buffering effect, which can reduce the impact and vibration of the material during the falling process, thereby protecting the material from damage.

[0043] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
