Description

Technical Field

[0001] This utility model relates to the field of plastic granule processing, and in particular to a wire feeding valve for plastic granule processing. Background Technology

[0002] A plastic granulator is a molding machine that can manufacture materials into specific shapes. It is mainly used to process plastic raw materials into granules. The extrusion valve, as the discharge component, plays a key role in this process, controlling the extrusion and molding of molten plastic.

[0003] If the diameter of the extruded plastic strip needs to be adjusted when using the existing wire ejector valve for plastic pellet processing, the entire wire ejector head needs to be removed and replaced. This process requires turning multiple fixing bolts, making the disassembly and assembly process cumbersome and affecting work efficiency.

[0004] Therefore, to address the issue that existing extrusion valves for plastic granule processing require the entire extrusion head to be disassembled and replaced when adjusting the diameter of the extruded plastic strip, a process involving the loosening of multiple fixing bolts is cumbersome and inefficient. A new extrusion valve for plastic granule processing can be designed with a sliding bar and extrusion orifices. The sliding bar is of a uniform specification, while the extrusion orifices have various diameters. When adjusting the diameter of the extruded plastic strip, simply pull out the sliding bar and replace it with one of a different diameter extrusion orifice. This eliminates the need to disassemble the entire extrusion head, simplifying operation and improving production efficiency. Utility Model Content

[0005] To overcome the problem that existing wire ejection valves for plastic pellet processing require the entire wire ejection head to be removed and replaced when the diameter of the extruded plastic strip needs to be adjusted, which involves turning multiple fixing bolts, making the disassembly and assembly process cumbersome and affecting work efficiency.

[0006] The technical solution of this utility model is as follows: a wire feeding valve for processing plastic granules, including a connecting seat; it also includes an extrusion head, a slide bar, a slider, an extrusion hole, and a limiting component. An extrusion tube is installed on the front surface of the connecting seat, and a flow divider is connected to the rear end of the extrusion tube. An extrusion head is provided on the rear side of the flow divider. A slide bar is provided at the outlet position of the extrusion head, and symmetrical sliders are provided on the side of the slide bar. The slide bar is slidably connected to the extrusion head through the sliders. Several equally spaced extrusion holes are opened on the bottom surface of the slide bar. Limiting components are provided on both the left and right sides of the extrusion head corresponding to the positions of the slide bar.

[0007] Preferably, by setting a slide bar and an extrusion orifice, with the slide bar being of a uniform specification and the extrusion orifice having multiple diameters, when it is necessary to adjust the diameter of the extruded plastic strip, it is only necessary to pull out the slide bar and replace it with a slide bar of a different diameter extrusion orifice. There is no need to disassemble the entire extrusion head for replacement, which is convenient for operation and helps to improve production efficiency. This solves the problem that when using the existing wire-ejection valve for plastic granule processing, if it is necessary to adjust the diameter of the extruded plastic strip, it is necessary to disassemble and replace the entire wire-ejection head, which is a cumbersome disassembly and assembly process and affects work efficiency.

[0008] Preferably, the limiting component includes a damping shaft and a lever; the left and right surfaces of the extruder are rotatably connected to the damping shaft, and the outer surface of the damping shaft is fitted with a lever.

[0009] Preferably, the rear surface of the flow divider is provided with a number of symmetrical first docking holes, and the rear surface of the extruder is provided with second docking holes at positions corresponding to the first docking holes.

[0010] Preferably, the front surface of the connector has several mounting holes near the edge.

[0011] Preferably, a slot is provided at the center of the front surface of the connector, and an arc-shaped liner is provided on the inner side of the slot.

[0012] Preferably, the front and rear surfaces of the flow divider are provided with flow divider grooves, the inner surface of the flow divider groove is provided with a stop block, and the bottom surface of the stop block is provided with a guide groove near the extrusion pipe.

[0013] Preferably, the bottom of the inner surface of the diversion channel is provided with two symmetrical inclined plates located below the baffle.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up a slider and an extrusion orifice, the slider is of a uniform specification, while the extrusion orifice has multiple diameters. When it is necessary to adjust the diameter of the extruded plastic strip, simply pull out the slider and replace it with a slider of a different diameter extrusion orifice. There is no need to disassemble the entire extrusion head for replacement, which is convenient for operation and helps to improve production efficiency. This solves the problem that when using the existing plastic granule processing wire valve, if it is necessary to adjust the diameter of the extruded plastic strip, the entire wire head needs to be disassembled and replaced, which is a cumbersome disassembly and assembly process and affects work efficiency.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 This utility model provides an embodiment of a filament valve for processing plastic granules, including a connecting seat 1; it also includes an extrusion head 4, a slide bar 5, a slider 6, extrusion holes 7, and a limiting component. An extrusion tube 2 is mounted on the front surface of the connecting seat 1, and a flow divider 3 is connected to the rear end of the extrusion tube 2. The extrusion head 4 is located on the rear side of the flow divider 3. A slide bar 5 is located at the outlet of the extrusion head 4, and symmetrical sliders 6 are located on the side of the slide bar 5. The slide bar 5 is slidably connected to the extrusion head 4 via the sliders 6. A plurality of equally spaced extrusion holes 7 are provided on the bottom surface of the slide bar 5. The left and right sides of the extrusion head 4... Limiting components are provided at the positions corresponding to the slide bar 5. By setting the slide bar 5 and the extrusion hole 7, the slide bar 5 is of uniform specification, while the extrusion hole 7 is set with multiple diameters. When it is necessary to adjust the diameter of the extruded plastic strip, it is only necessary to pull out the slide bar 5 and replace it with a slide bar 5 with an extrusion hole 7 of a different diameter. There is no need to remove the entire extrusion head 4 for replacement, which is convenient for operation and helps to improve production efficiency. This solves the problem that when the diameter of the extruded plastic strip needs to be adjusted in the existing plastic granule processing filament valve, the entire filament head needs to be removed for replacement, which is a cumbersome disassembly and assembly process and affects work efficiency.

[0023] Please see Figure 1 , Figure 2 and Figure 4In this embodiment, the limiting component includes a damping shaft 801 and a lever 802. The left and right sides of the extruder head 4 are rotatably connected to the damping shaft 801, and the outer surface of the damping shaft 801 is fitted with the lever 802. By setting the damping shaft 801 and the lever 802, after the slide bar 5 is inserted into the extruder head 4, the levers 802 on both sides are moved to rotate and fit with the sides of the slide bar 5, thus limiting the slide bar 5 and preventing it from loosening during use. The rear surface of the diverter seat 3 is provided with several symmetrical first docking holes 9, and the rear surface of the extruder head 4 is provided with second docking holes 10 at the positions corresponding to the first docking holes 9. By setting the first docking holes 9 and the second docking holes 10, it is convenient for the operator to accurately dock the diverter seat 3 and the extruder head 4, thereby improving production accuracy. The front surface of the connecting seat 1 is provided with several mounting holes 11 near the edge. By setting the mounting holes 11, it is convenient for the operator to quickly position and install the connecting seat 1 and the die head.

[0024] Please see Figure 1 , Figure 2 and Figure 4 In this embodiment, a slot 12 is provided at the center of the front surface of the connecting seat 1, and an arc-shaped liner 13 is provided on the inner side of the slot 12. By providing the slot 12 and the arc-shaped liner 13, the arc-shaped liner 13 can reduce the diameter of the rear end of the slot 12, thereby making the plastic raw material flow more tightly and improving product quality. A diversion groove 14 is provided on the front and rear surfaces of the diversion seat 3, and a stop 15 is provided on the upper side of the inner surface of the diversion groove 14. The bottom surface of the stop 15 A guide groove 16 is provided near the extrusion tube 2. By setting the baffle 15 and the guide groove 16, the two are combined to form a pressure-changing cavity that is shallow in the middle and deep on both sides. During discharge, the flow velocity in the middle is faster and the flow velocity on both sides is slower, forming a flow velocity difference, thereby improving the uniformity of the extruded filament. The bottom of the inner surface of the diversion groove 14 is provided with two symmetrical inclined plates 17 located below the baffle 15. By setting the inclined plates 17, the uniformity of the flow of plastic raw materials can be improved, thus cooperating with the baffle 15 to improve the uniformity of the discharge.

[0025] During operation, by setting up the damping shaft 801 and the lever 802, after inserting the slide bar 5 into the extrusion head 4, the levers 802 on both sides are moved to rotate and engage with the sides of the slide bar 5, thus limiting the slide bar 5 and preventing loosening during use. The first docking hole 9 and the second docking hole 10 facilitate precise docking of the distributor seat 3 and the extrusion head 4, improving production accuracy. The mounting hole 11 facilitates quick positioning and installation of the connecting seat 1 and the die head. By setting the slot 12 and the arc-shaped liner 13, the arc-shaped liner 13 can reduce the diameter of the rear end of the slot 12, so that the plastic raw material can be made more compact when it flows through, thereby improving the product quality. By setting the baffle 15 and the guide groove 16, the two are combined to form a pressure-changing cavity that is shallow in the middle and deep on both sides. During the discharge, the flow velocity in the middle is faster and the flow velocity on both sides is slower, forming a flow velocity difference, thereby improving the uniformity of the extrusion. By setting the inclined plate 17, the uniformity of the flow of plastic raw material can be improved, thus cooperating with the baffle 15 to improve the uniformity of the discharge.

[0026] Through the above steps, by setting the slide bar 5 and the extrusion hole 7, the slide bar 5 is of uniform specification, while the extrusion hole 7 is set with multiple diameters. When it is necessary to adjust the diameter of the extruded plastic strip, it is only necessary to pull out the slide bar 5 and replace it with a slide bar 5 with an extrusion hole 7 of a different diameter. There is no need to disassemble and replace the entire extrusion head 4, which is convenient for operation and helps to improve production efficiency. This solves the problem that when the diameter of the extruded plastic strip needs to be adjusted in the existing plastic granule processing wire valve, it is necessary to disassemble and replace the entire wire head, which is a cumbersome disassembly and assembly process and affects work efficiency.
