Description

Technical Field

[0001] The utility model relates to the technical field of extruder material guiding, in particular to a plastic processing extruder material guiding device. Background Art

[0002] The material guide device of the plastic processing extruder is an important component of the plastic processing equipment. It is mainly used to receive the molten plastic extruded from the extruder and guide it to the next processing link. This device is usually located at the outlet of the extruder.

[0003] In the plastic extrusion process, the molten plastic strip needs to be smoothly guided by the guide wheel to the next processing link. However, due to the lack of buffering effect of the guide wheel, when the plastic strip contacts it, sudden and strong impact often occurs. This impact will not only damage the guide wheel itself, but more importantly, it will cause the originally soft and elastic plastic strip to be subjected to sudden stress, resulting in uneven internal stress distribution. When the internal stress of the plastic strip exceeds its tolerance limit, it will break, which will not only make it impossible to continue the subsequent processing process, but also cause material waste and increase production costs. Therefore, we propose a guide device for a plastic processing extruder. Utility Model Content

[0004] The utility model aims to provide a material guiding device for a plastic processing extruder, so as to solve the problem proposed in the above background technology that in the process of plastic extrusion, the molten plastic strip needs to be smoothly guided to the next processing link by a guide wheel. However, since the guide wheel lacks a buffering effect, when the plastic strip contacts it, a sudden and strong impact often occurs. This impact not only causes damage to the guide wheel itself, but more importantly, it causes the originally soft and elastic plastic strip to be subjected to sudden stress, resulting in uneven internal stress distribution. When the internal stress of the plastic strip exceeds its bearing limit, fracture will occur, which not only makes it impossible to continue the subsequent processing process, but also causes material waste and increased production costs.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a material guiding device for a plastic processing extruder, comprising a shell, fixed plates are fixedly connected to the two side positions in the shell, adjusting screws are threadedly connected to the two side positions of the top and bottom of the shell, movable plates are arranged at the top and bottom of one side of the two fixed plates, the bottom and one side of the top of the two movable plates arranged up and down are fixedly connected to hinge seats, one side of the hinge seat is hingedly connected to a movable frame, one end of the rear surface of the movable frame is movably mounted with a guide wheel, the top and bottom of the four movable frames are fixedly connected to connecting blocks near the center, and the tops and bottoms of the four connecting blocks are fixedly connected to springs.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] The material guide device of the plastic processing extruder is designed with a fixed plate, a movable plate, a hinged seat, a movable frame, a guide wheel, a connecting block and a spring. When the extruded plastic strip passes through the guide wheel, due to the presence of the spring, the guide wheel can be adjusted according to the pressure and speed of the plastic strip, providing necessary buffering for the guide wheel. This buffering not only ensures the smooth passage of the plastic strip, but also greatly reduces the possibility of the plastic strip being broken due to sudden impact. At the same time, due to the adjustment effect of the spring, the guide wheel can better adapt to plastic materials with different hardness and viscosity, thereby improving the adaptability and stability of the equipment. The design of the adjusting screw can push the movable plate and the guide wheel at the bottom to move by rotating the adjusting screw, thereby adjusting the spacing between the upper and lower guide wheels, and can be adjusted for plastics of different coarsenesses. It is practical and convenient, thereby improving the practicality of the material guide device. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] A feed port and a discharge port are respectively provided on both sides of the shell 1. A mounting plate is fixedly connected to one end of the shell 1 corresponding to the feed port, and a mounting hole is provided on the mounting plate. A groove 13 is provided in the center of one side of the two fixing plates 2. The feed port and the discharge port are used for the input and output of plastic strips to achieve the continuity of the entire processing process. The mounting plate and the shell 1 can be fixed to the discharge port of the extruder by bolts passing through the mounting holes.

[0016] One end of the four adjusting screws 3 corresponds to a knob 4 fixedly installed on the outside of the shell 1, and the bottom and top of the four adjusting screws 3 arranged up and down penetrate into the interior of the shell 1 and are movably connected with the bearings fixedly installed at the top and bottom centers of the four movable plates 5 respectively, so that the operator can easily adjust the position of the adjusting screw 3 by rotating the knob 4, thereby controlling the position and pressure of the movable plate 5 and the guide wheel 8.

[0017] One side of the four movable plates 5 is fixedly connected with a slider 12, and the top and bottom of one side of the fixed plate 2 are provided with a slide groove 11. One side of the four sliders 12 extends to the inside of the four slide grooves 11 respectively and is slidably connected to the inner wall of the slide groove 11, so that the movable plate 5 can move in the vertical direction under the control of the adjusting screw 3 to adapt to different processing requirements.

[0018] The four movable frames 7 arranged up and down are arranged in an eight-shaped structure. The upper and lower ends of the four springs 10 arranged up and down are fixedly connected to the bottom and top of the four movable plates 5 respectively, so that the guide wheel 8 can have a certain elastic deformation when subjected to pressure, thereby reducing the direct impact on the plastic strip material.

[0019] A water inlet plate 14 is fixedly installed at the center of the top of the shell 1, and a nozzle 15 is fixedly connected to the lower end of the water inlet plate 14. A water inlet pipe 16 is fixedly connected to the center of the top of the water inlet plate 14, and the upper end of the water inlet pipe 16 passes through the outside of the shell 1, which is used to introduce cooling water into the material guiding device to cool and solidify the plastic strips.

[0020] A drainage bucket 17 is fixedly installed at the center of the bottom of the shell 1, and the lower end of the drainage bucket 17 penetrates to the outside of the shell 1 for draining the sprayed water.

[0021] Working principle: The plastic strip enters the guide device through the feed port on one side of the shell 1. During the guiding process, the plastic strip will contact the upper and lower guide wheels 8. In order to ensure the smooth guiding of the plastic strip and reduce the breakage caused by excessive pressure, the device is designed with an adjustable movable plate 5 and a spring 10 as a buffer mechanism. When the plastic strip passes through the guide wheel 8, if it is subjected to excessive pressure, the movable frame 7 will undergo a slight deformation due to its figure-eight structure design and the elastic effect of the spring 10, thereby absorbing part of the impact force and reducing the direct impact on the plastic strip. At the same time, the elastic force of the spring 10 will also be automatically adjusted according to the pressure and speed of the plastic strip to maintain appropriate pressure to ensure the stable guiding of the plastic strip. The position and pressure of the movable plate 5 can be adjusted by adjusting the screw 3. The operator can drive the rotation of the adjusting screw 3 by rotating the knob 4, so that the movable plate 5 can move up and down in the slide groove 11 of the fixed plate 2. This design allows the operator to adjust the position and pressure of the guide wheel 8 according to the plastic strips of different sizes and hardness to meet different processing requirements. In addition, in order to cool and solidify the plastic strips, the device installs a water inlet plate 14 and a nozzle 15 at the top center of the shell 1. The cooling water enters the water inlet plate 14 through the water inlet pipe 16, and is then evenly sprayed on the plastic strips through the nozzle 15. The sprayed cooling water can not only reduce the temperature of the plastic strips, but also remove impurities and oil stains on the surface to improve product quality. Finally, the sprayed cooling water is discharged from the outside of the shell 1 through the drainage bucket 17 to keep the inside of the material guiding device dry and clean.

[0022] To sum up: the material guiding device of the plastic processing extruder is designed with a fixed plate 2, a movable plate 5, a hinged seat 6, a movable frame 7, a guide wheel 8, a connecting block 9 and a spring 10. When the extruded plastic strip passes through the guide wheel 8, due to the presence of the spring 10, the guide wheel 8 can be adjusted according to the pressure and speed of the plastic strip, providing necessary buffering for the guide wheel 8. This buffering not only ensures the smooth passage of the plastic strip, but also greatly reduces the possibility of the plastic strip breaking due to sudden impact. At the same time, due to the regulating effect of the spring 10, the guide wheel 8 can better adapt to plastic materials of different hardness and viscosity, thereby improving the adaptability and stability of the equipment. The design of the adjusting screw 3 can push the movable plate 5 and the guide wheel 8 at the bottom to move by rotating the adjusting screw 3, thereby adjusting the spacing between the upper and lower guide wheels 8, and can be adjusted for plastics of different coarsenesses. It is practical and convenient, thereby improving the practicality of the material guiding device.
