Description

Technical Field

[0001] This invention relates to the field of injection molding machine technology, and in particular to an injection molding machine for recycling modified nylon waste with a cutting function. Background Technology

[0002] Modified nylon is a new type of polymer material obtained by modifying nylon material. During the processing of modified nylon, scrap and cutting waste are generated in molding processes such as injection molding and extrusion. Therefore, the modified nylon waste can be recycled and remelted into products for use in injection molding machines.

[0003] In existing injection molding machines, when faced with large-volume modified nylon waste, a cutting mechanism is needed for pre-treatment to facilitate the subsequent melt injection molding process.

[0016] In use, this invention utilizes the cooperation between the lower and upper guide blocks to move the cutting tool up and down during rotation as the cutting tool rotates synchronously with the rotating rod. This cuts through the modified nylon waste wrapped around the outside of the rotating rod, preventing the waste from entangled and hindering the rotation of the rod. This significantly increases the rotational speed of the rotating rod, thereby accelerating the continuous cutting of the modified nylon, shortening the cutting time, and allowing the cut modified nylon to quickly enter the injection molding body for injection molding. This improves the production efficiency of modified nylon. At the same time, the increased rotational speed of the rotating rod reduces energy waste caused by downtime for cleaning, reduces the risk of operators directly contacting high-speed rotating parts or sharp cutting tools, and improves operational safety.

[0017] Furthermore, the connection between the guide channel and the flow cavity allows the cooling airflow generated by the cooling component to enter the interior of the cooling cavity evenly. This cooling airflow cools the blades on the outside of the positioning cover, preventing local melting of the modified nylon due to frictional heat during high-speed cutting. It also prevents molten material from adhering to the blade surface, ensuring blade sharpness and cutting smoothness, inhibiting the adhesion of molten modified nylon, reducing the frequency of cutting tool replacement, extending blade life, reducing maintenance costs, and preventing softening and deformation of the modified nylon during cutting. This reduces the impact of adhesion on the flow rate of the modified nylon and improves the production efficiency of modified nylon. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please refer to Figures 1 to 9 :

[0037] Example 1:

[0038] This invention proposes an injection molding machine for recycling modified nylon waste with a cutting function, comprising: an outer feed cover 1 and an injection molding body 4. The bottom of the outer feed cover 1 is conical, and the bottom of the outer feed cover 1 is installed on the top of the injection molding body 4. An inner feed cover 101 is installed on the top inner side of the outer feed cover 1. A fixed support plate 102 is installed on the top of the inner feed cover 101, and a drive motor is installed on the top of the fixed support plate 102. Three partitions 103 are provided on the inner side of the inner feed cover 101. The partitions 103 are circular, and each of the three partitions 103 has an opening of a different diameter, which gradually decreases in size from top to bottom. A rotating rod 104 is installed on the output end of the drive motor on the top of the fixed support plate 102. A rotating plate 105 is installed on the outer side of the rotating rod 104. The rotating plate 105 is rotatably installed in the middle position of the partitions 103. A positioning cover 106 is provided, with a blade on its outer side; a positioning plate 107 is installed on the top of the rotating rod 104; a spring is installed on the bottom of the positioning plate 107, and a movable plate 108 is installed on the bottom of the positioning plate 107 via the spring; the movable plate 108 is slidably installed on the outer side of the rotating rod 104, and a connecting rod 109 is installed on the bottom of the movable plate 108; the connecting rod 109 slides through the bottom of the rotating plate 105, and a cutting tool 1010 is installed on the outer side of the connecting rod 109; the cutting tool 1010 slides through the bottom of the positioning cover 106; two upper guide blocks 1011 are installed on the bottom of the inner feed cover 101, wherein the upper guide blocks 1011 have an arc-shaped structure; a rotating base plate 1012 is installed on the bottom of the two connecting rods 109; a lower guide block 1013 is provided on the top of the rotating base plate 1012; the lower guide block 1013 is slidably installed on the outer side of the upper guide block 1011.

[0039] In this embodiment, when the recycled modified nylon waste is injection molded, the recycled modified nylon is placed inside the inner feed cover 101. The drive motor at the top of the fixed support plate 102 drives the rotating rod 104 to rotate the rotating plate 105 in the middle position of the partition 103. The rotating rod 104 drives the blade on the outside of the positioning cover 106 to cut the recycled modified nylon. After the blade on the outside of the upper positioning cover 106 cuts the modified nylon, it falls through the opening on the partition 103 and falls into the lower area to cut in the same way, reducing the diameter of the modified nylon cut. It then flows through the three partitions 103 to the inside of the outer feed cover 1, and then enters the injection molding body 4 for injection molding. During the rotation of the rotating rod 104, the rotating plate 105 positions the two connecting rods 109. The movable plate 108 at the top of the connecting rod 109 is positioned on the positioning plate. When the bottom spring of 107 moves upward, the bottom of the connecting rod 109 drives the rotating base plate 1012 to rotate synchronously. When the lower guide block 1013 at the top of the rotating base plate 1012 contacts the upper guide block 1011, it moves downward, causing the rotating base plate 1012 to drive the connecting rod 109 to move downward. When the lower guide block 1013 leaves the upper guide block 1011, it moves upward under the action of the spring, causing the connecting rod 109 to drive the outer cutting tool 1010 to move up and down on the outside of the rotating rod 104. The cutting tool 1010 cuts the modified nylon wound on the rotating rod 104, preventing the wound modified nylon waste from affecting the efficiency of the rotating rod 104 driving the blade to cut the modified nylon, increasing the rotation speed of the blade, and quickly cutting the modified nylon. The cut modified nylon flows downward to facilitate injection molding.

[0040] In Example 2, based on Example 1, a cooling component 2 is installed on the outside of the feed shroud 1; a guide pipe 201 is installed on the output end of the bottom of the cooling component 2; the guide pipe 201 passes through the outside of the feed shroud 1 and an air inlet shroud 202 is installed; a flow cavity 203 is opened inside the rotating rod 104, and guide grooves 204 are opened on the top and bottom outer sides of the rotating rod 104, and an air outlet groove 205 is opened on the outer side of the rotating rod 104; the inner sides of the guide grooves 204 and the air outlet grooves 205 are connected to the flow cavity 203; An air shroud 202 is installed at the bottom of the rotating rod 104; the lower guide groove 204 is located inside the air inlet shroud 202; a cooling chamber 206 is provided inside the positioning cover 106 and the blade on its outer side; the air outlet groove 205 is connected to the interior of the cooling chamber 206; a return pipe 207 is installed on the input end of the top of the refrigeration assembly 2; the return pipe 207 passes through the side of the fixed support plate 102 and an air outlet shroud 208 is installed; the air outlet shroud 208 is installed on the outer side of the rotating rod 104; the upper guide groove 204 is located inside the air outlet shroud 208. During injection molding of recycled modified nylon waste, the rotating rod 104 rotates inside the air inlet hood 202 and the air outlet hood 208. The cooling airflow generated by the cooling component 2 enters the air inlet hood 202 through the guide pipe 201. The airflow then enters the flow chamber 203 through the lower guide groove 204. The airflow inside the flow chamber 203 enters the cooling chamber 206 inside the positioning cover 106 through multiple air outlet grooves 205. The cooling airflow cools the blades on the outside of the positioning cover 106, preventing... During the cutting process, the blade heats up, causing the modified nylon to melt and affecting the blade's sharpness. To ensure the blade can quickly cut the modified nylon waste, and to prevent the modified nylon from melting and adhering, the airflow inside the flow cavity 203 continuously flows upward through the upper guide groove 204 to the inside of the air outlet hood 208. The airflow enters the interior of the cooling component 2 through the return pipe 207 for further cooling treatment, reducing the power consumption of the cooling air in the cooling component 2, and making the cooling airflow circulate, ensuring efficient cutting of the modified nylon waste.

[0041] In Example 3, based on Example 1, an air pump is installed on the bottom of the other outer side of the feed hood 1, and a connecting pipe 3 is installed on the bottom of the inner side of the feed hood 1; a guide pipe 302 is installed on the side end of the connecting pipe 3, wherein the side end of the guide pipe 302 is connected to the output end of the air pump on the bottom of the other outer side of the feed hood 1; a circulating pipe 301 is connected to the outside of the connecting pipe 3; the circulating pipe 301 is an annular structure of different diameters, and an opening is provided at the top of the circulating pipe 301, and the circulating pipe 301 is located at the bottom of the inner side of the feed hood 1; a storage tank 303 is installed on the outside of the feed hood 1; the storage tank 3... The bottom of tank 303 is connected to the top of guide pipe 302, and a positioning inner plate 304 is installed on the inner side of tank 303; a diversion rotating wheel 305 is rotatably mounted on the positioning inner plate 304; a groove is provided on the outer side of the diversion rotating wheel 305, and multiple evenly distributed storage slots are provided on the outer side of the diversion rotating wheel 305; a transmission vertical rod 306 is rotatably mounted on the bottom of positioning inner plate 304; the transmission vertical rod 306 has a cylindrical structure, and the bottom of the transmission vertical rod 306 is rotatably mounted inside guide pipe 302, and a fan blade is provided on the outer side of the bottom of the transmission vertical rod 306, the fan blade being located in the guide pipe 302. Inside, a lever 307 is provided on the outer side of the top of the transmission vertical rod 306; the lever 307 is rotatably mounted on the outer side of the diverting rotary wheel 305. When the recycled modified nylon waste is injection molded, the air pump on the outer side of the feed cover 1 works, and the hot airflow generated by the air pump enters the interior of the connecting pipe 3 through the guide pipe 302, causing the hot airflow to be diverted to the interior of the circulation pipe 301. The hot airflow flows out through the opening at the top of the circulation pipe 301 to heat and pre-treat the crushed modified nylon waste. When the airflow flows inside the guide pipe 302, the airflow drives the bottom of the transmission vertical rod 306. The fan blades on the outer side of the part rotate, and the transmission vertical rod 306 drives the lever 307 to rotate. The lever 307 causes the diversion rotating wheel 305 to rotate on the positioning inner plate 304 inside the storage tank 303. The storage tank 303 stores silicone, polyether and other defoamers. After the defoamer rotates through the groove on the outer side of the diversion rotating wheel 305, it falls into the inside of the guide pipe 302. The airflow carries the defoamer out through the opening on the circulation pipe 301. The defoamer, together with the heating of the modified nylon, can solve the problem of air bubbles in the modified nylon during the injection molding process, and further improve the injection molding quality of the modified nylon.

[0042] The working principle of this embodiment is as follows: During use, the recycled modified nylon is placed into the inner feed cover 101. The drive motor at the top of the fixed support plate 102 drives the rotating rod 104 to move the blade on the outside of the positioning cover 106 to cut the modified nylon. After cutting, the modified nylon falls through the opening on the partition plate 103 and is cut again in the lower area. The diameter of the cut modified nylon is reduced and flows through the three partition plates 103 into the outer feed cover 1 before entering the injection molding body 4 for injection molding. During the rotation of the rotating rod 104, the rotating plate 105 fixes the two connecting rods 109. Position, the movable plate 108 at the top of the connecting rod 109 moves upward under the traction of the spring. When the bottom of the connecting rod 109 drives the lower guide block 1013 at the top of the rotating base plate 1012 to contact the upper guide block 1011, it moves downward. The rotating base plate 1012 drives the connecting rod 109 to move downward. When the lower guide block 1013 leaves the upper guide block 1011, it moves upward under the action of the spring. The connecting rod 109 drives the outer cutting tool 1010 to move up and down on the outside of the rotating rod 104 to cut the wound modified nylon. At the same time, the cooling component 2 produces The generated cooling airflow enters the inlet hood 202 through the guide pipe 201, and then enters the flow chamber 203 through the lower guide groove 204. The airflow inside the flow chamber 203 enters the cooling chamber 206 through multiple outlet grooves 205 to cool the blades on the outside of the positioning cover 106, ensuring their sharpness. The airflow continues to flow upwards, passing through the upper guide groove 204 to the outlet hood 208, and then returns through the return pipe 207 to the cooling assembly 2 for further cooling and circulation. The airflow generated by the pump outside the feed hood 1... Hot airflow enters the connecting pipe 3 through the guide pipe 302 and then splits into the circulation pipe 301. When the airflow flows inside the guide pipe 302, it drives the fan blades on the outer side of the bottom of the transmission vertical rod 306 to rotate. The transmission vertical rod 306 drives the lever 307 to rotate the diverting rotating wheel 305, which guides the defoamer stored in the storage tank 303 into the guide pipe 302. The airflow carrying the defoamer flows out through the opening on the circulation pipe 301. The defoamer, together with the heating of the modified nylon, reduces the problem of air bubbles in the injection molding process and improves the injection molding quality of the modified nylon.
