Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to an adaptive extrusion device for plastic processing. Background Technology

[0002] An extruder is an important piece of equipment used in plastics processing and other fields. It is mainly used to heat and pressurize solid plastic raw materials to make them melt and continuously extrude them into plastic products with specific shapes and sizes.

[0003] In existing technologies, plastics need to be molten and extruded through an extruder during processing. The plastic is then extruded into various shapes, such as pipes, sheets, and wires, through the die of the extruder to meet the needs of different application scenarios. By optimizing the extrusion process, plastic parts can meet the requirements of lightweighting while also having sufficient strength and weather resistance to adapt to complex usage environments.

[0004] However, during the extrusion process, the pipe needs to be cut to the required length. When dealing with longer pipes, since the temperature has not fully degraded after extrusion and the material is relatively soft, if the receiving object is fixed, the longer pipe is prone to bending, denting, or twisting at the fixed receiving position under its own weight. Therefore, we propose an adaptive extrusion device for plastic processing. Utility Model Content

[0005] One of the technical problems to be solved by this application is that when receiving pipes of different lengths, the receiving object can be adjusted accordingly as needed.

[0006] To address the aforementioned technical problems, this application provides an adaptive plastic extrusion apparatus, including a receiving mechanism.

[0008] In some embodiments, an outer ring is provided on the outer side of the sub-ring, the outer side of the sub-ring is rotatably connected to the inner side of the outer ring, one end of the outer ring is fixedly connected to one end of the connecting ring, and one bottom side of the outer ring is fixedly connected to one end of the base.

[0009] In some embodiments, an extruder is provided on the outer side of the base, and the outer side of the base is slidably connected to the inner wall of the bottom end of the extruder. An insert rod is provided on the inner wall of the bottom end of the extruder, and the inner wall of the bottom end of the extruder is slidably connected to the outer side of the insert rod. One end of the insert rod is slidably engaged with one end of the inner wall of the base.

[0010] In some embodiments, one end of the extruder is provided with a discharge pipe, one end of the extruder is fixedly connected to one end of the discharge pipe, one end of the discharge pipe is rotatably corresponding to the corner hole of the sub-ring, and one end of the sub-ring is fixedly connected to the output end of the motor.

[0011] In some embodiments, a cavity is provided at one end of the side of the mother ring, and the side of the mother ring is rotatably connected to one end of the cavity. A spring is provided on the inner surface of the cavity, and one end of the spring is fixedly connected to the inner surface of the cavity.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. After the plastic is extruded, it first enters the hole corresponding to the discharge tube. When it is extruded to a certain length, a cutter is designed on the bottom side of one end of the connecting ring. By starting the motor, the sub-ring starts to rotate at a small angle, so that the second hole corresponds to the discharge tube. Then, the cutter cuts the extruded plastic in this process, realizing the fixed-length cutting operation of the extruded plastic. This allows the sub-ring and the mother ring to merge. In this way, when dealing with extra-long plastic, the plastic can extend smoothly along the channel formed by the corresponding holes of the mother ring and the sub-ring during the extrusion process, ensuring the stability and shape regularity of the plastic when extruded at a long length, and avoiding bending and twisting problems due to excessive length.

A spring is installed on the inner surface of the cavity, and the other end of the spring is fixedly connected to the locking rod. At the same time, the outer side of one end of the locking rod is located inside the cavity. In order to ensure a stable connection between the daughter ring and the mother ring, the locking rod can be pulled so that the groove on the inner wall of the locking rod is located on one side of the latch. Then, a small angle rotation is made so that the groove of the locking rod engages with the latch, thereby completing the stable connection between the daughter ring and the mother ring.

The outer side of the daughter ring 13 is rotatably connected to the inner side of the outer ring 16. One end of the outer ring 16 is fixedly connected to one end of the connecting ring 14. One side of the bottom end of the outer ring 16 is fixedly connected to one end of the base 18. An extruder 11 is provided on the outer side of the base 18. The outer side of the base 18 is slidably connected to the inner wall of the bottom end of the extruder 11. The bottom inner wall of the extruder 11 is provided with a rod 19. The bottom inner wall of the extruder 11 is slidably connected to the outer side of the rod 19. The outer side of one end of the rod 19 is slidably engaged with the inner wall of one end of the base 18. One end of the extruder 11 is provided with a discharge pipe 12. One end of the extruder 11 is fixedly connected to one end of the discharge pipe 12. One end of the discharge pipe 12 is rotatably aligned with the corner hole of the sub-ring 13. One end of the sub-ring 13 is fixedly connected to the output end of the motor 17. One side of the mother ring 110 is provided with a cavity 115. One side of the mother ring 110 is connected to the cavity. One end of 115 is rotatably connected, and a spring piece 111 is provided on the inner surface of the cavity 115. The inner surface of the cavity 115 is fixedly connected to one end of the spring piece 111. A locking rod 112 is provided on the other end of the spring piece 111. The other end of the spring piece 111 is fixedly connected to one end of the locking rod 112. The outer side of the locking rod 112 is slidably connected to the inner surface of the cavity 115. A latch 113 is provided on the inner wall of the locking rod 112. The inner wall of the locking rod 112 is rotatably engaged with the outer side of the latch 113. One end of the latch 113 is fixedly connected to one side of the sub-ring 13.

[0027] In use, this type of adaptive plastic processing extrusion device first melts the plastic in the extruder 11 and then extrudes it from the discharge pipe 12. Since the outlet of the discharge pipe 12 is circular, the extruded plastic is naturally extruded in a cylindrical manner. Furthermore, one end of the extruder 11 is designed with a sub-ring 13, the edge of which has ten holes. Therefore, after extrusion, the plastic first enters the holes corresponding to the discharge pipe 12. When it reaches a certain length, a connecting ring 14 is designed on the outside of the sub-ring 13, and a cutter 15 is designed on the bottom side of one end of the connecting ring 14. The two are fixedly connected at this point. By starting the motor 17, the sub-ring 13 begins to rotate at a small angle, aligning the second hole with the discharge pipe 12. Simultaneously, the connecting ring 14 remains stationary during the rotation of the sub-ring 13. Then, the cutter 15 cuts the extruded plastic, achieving a fixed-length cutting operation for the extruded plastic. This ensures that the length of the plastic extruded and cut is relatively consistent each time, guaranteeing the uniformity of the specifications of the plastic processed products. Furthermore, through the design of multiple holes on the sub-ring 13 and the rotation switching of the sub-ring 13, the extrusion and cutting of plastic can be performed continuously, improving the working efficiency of this adaptive plastic processing extrusion device.

[0028] By fitting the fitting tube 114 on the mother ring 110 to the inner wall of the daughter ring 13, the daughter ring 13 and the mother ring 110 are merged. At the same time, the holes on the daughter ring 13 and the holes on the mother ring 110 are connected. In this way, when dealing with extra-long plastics, the plastic can extend smoothly along the channel formed by the corresponding connected holes of the mother ring 110 and the daughter ring 13 during the extrusion process. This ensures the stability and shape regularity of the plastic during extrusion at longer lengths and avoids problems such as bending and twisting due to excessive length.

[0029] After the mother ring 110 and the daughter ring 13 are connected, a cavity 115 is designed on one side of the mother ring 110. The two are rotatably connected. A spring is installed on the inner surface of the cavity 115. The other end of the spring is fixedly connected to the locking rod 112. At the same time, the outer side of one end of the locking rod 112 is located inside the cavity 115. In order to ensure a stable connection between the daughter ring 13 and the mother ring 110, a latch 113 is designed on one side of the daughter ring 13. When the daughter ring 13 and the mother ring 110 are joined together, the locking rod 112 can be pulled so that the groove on the inner wall of the locking rod 112 is located on one side of the latch 113. Then, a small angle rotation is performed so that the groove of the locking rod 112 engages with the latch 113, thereby completing the stable connection between the daughter ring 13 and the mother ring 110.

[0030] When connecting the sub-ring 13 to the extruder 11, since an outer ring 16 is designed on the outside of the sub-ring 13, the two are rotatably connected. One side of the outer ring 16 is fixedly connected to one end of the base 18. By placing one side of the base 18 in the base 18 of the extruder 11, and then pushing the insert rod 19 along the groove of the base 18 of the extruder 11, the insert rod 19 enters the inner wall of the base 18. At this time, the sub-ring 13 and the extruder 11 have a preliminary structural connection. Then, the insert rod 19 is connected to the base 18 of the extruder 11 by using bolts. This connection method not only ensures that the sub-ring 13 can rotate stably on the extruder 11 to cooperate with plastic extrusion and cutting operations, but also makes it easy to remove it from the extruder 11 when the equipment needs maintenance, repair or replacement of parts.

[0031] Example 2: Please refer to Figure 3 The protective mechanism 2 includes a housing 21, an L-shaped rod 22 is provided on the bottom side of the housing 21, the bottom side of the housing 21 is fixedly connected to the top end of the L-shaped rod 22, a base 18 is provided at the bottom end of the L-shaped rod 22, the bottom end of the L-shaped rod 22 is fixedly connected to the inner wall of one side of the base 18, and a motor 17 is provided on the inner surface of the housing 21, the inner surface of the housing 21 is in contact with the outer side of the motor 17.

[0032] A housing 21 is designed on the outside of the motor 17. By inserting the L-rod 22 on the bottom side of the housing 21 into the inner side wall of the base 18, the housing 21 covers the outside of the motor 17. Since the motor 17 is located in the middle and below the sub-ring 13 and the discharge pipe 12, the connection between the housing 21 and the base 18 through the L-rod effectively protects the motor 17, preventing it from being damaged by external factors during plastic processing, extending the service life of the motor 17, and improving the stability and reliability of the entire extrusion device.

[0033] Please see Figures 1-6After the plastic is extruded, it first enters the hole corresponding to the discharge pipe 12. When it reaches a certain length, a connecting ring 14 is designed on the outside of the sub-ring 13, and a cutter 15 is designed on the bottom side of one end of the connecting ring 14. The two are fixedly connected. At this time, the motor 17 is started to make the sub-ring 13 start to rotate at a small angle, so that the second hole corresponds to the discharge pipe 12. At the same time, the connecting ring 14 remains stationary during the rotation of the sub-ring 13. Then, the cutter 15 cuts the extruded plastic, realizing the fixed-length cutting operation of the extruded plastic, so that the length of the plastic extruded and cut each time is relatively consistent. The fitting tube 114 on the mother ring 110 is fitted and connected to the inner wall of the sub-ring 13, so that the sub-ring 13 and the mother ring 110 are merged. At the same time, the holes on the sub-ring 13 and the holes on the mother ring 110 are connected. In this way, when dealing with extra-long plastic, During the extrusion process, the plastic can extend smoothly along the channel formed by the corresponding holes of the mother ring 110 and the daughter ring 13, ensuring the stability and shape regularity of the plastic during long-distance extrusion. A cavity 115 is designed on one side of the mother ring 110, and the two are rotatably connected. A spring is installed on the inner surface of the cavity 115, and the other end of the spring is fixedly connected to the locking rod 112. At the same time, the outer side of one end of the locking rod 112 is located inside the cavity 115. In order to ensure a stable connection between the daughter ring 13 and the mother ring 110, a latch 113 is designed on one side of the daughter ring 13. When the daughter ring 13 and the mother ring 110 are joined, the locking rod 112 can be pulled so that the groove on the inner wall of the locking rod 112 is located on one side of the latch 113. Then, a small angle rotation is performed so that the groove of the locking rod 112 engages with the latch 113, so that the daughter ring 13 and the mother ring 110 can be stably attached after being joined.
