Description

Technical Field

[0001] The present application relates to the field of plastic production equipment, and in particular to a feeding device for plastic granulation. Background Art

[0002] Plastic granulator is a mechanical equipment that converts various raw materials into granular plastic particles through a series of processes such as heating, melting, extrusion and cutting.

[0003] The raw materials for plastic granulators come in various forms, including granular raw materials and strip-shaped coils. When the raw materials for the plastic granulator are strip-shaped coils, the staff will place the coils on the ground on one side of the plastic granulator, then pull the surface material after the inner ring of the coil is unwound to the feeding mechanism of the plastic granulator, and then convey it to the melt extrusion mechanism through the conveying components such as the conveyor rollers of the plastic granulator.

[0004] In existing technology, unwinding a coil into a single layer of surface material primarily relies on the traction of the plastic granulator's conveyor mechanism. Due to the obstruction of the coil's inner circumference, the unwinding speed of the surface material varies from area to area. This makes the surface material susceptible to oscillation under the influence of uneven external forces, thus affecting the stability of the surface material feeding. Utility Model Content

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application discloses a feeding device for plastic granulation. Figure 1 The feeding device for plastic pelletizing includes a workbench 1 and a tensioning mechanism 2. The workbench 1 has a work area for accommodating a coil 4. After the coil 4 is unwound into a surface material 5, the surface material 5 is conveyed to the feeding mechanism of the plastic pelletizer. The tensioning mechanism 2 is mounted on the workbench 1 and is located on the side of the work area near the plastic pelletizer.

[0034] Reference Figure 1 The tensioning adjustment mechanism 2 includes at least two spaced apart tensioning assemblies 3. In this embodiment, two spaced apart tensioning assemblies 3 are provided. The tensioning assemblies 3 include a vertical rod 31, a tensioning rod 32, a first rubber sheet 33, a limiting sleeve 34, and a limiting bolt 35.

[0035] Reference Figure 1 The vertical rod 31 is arranged vertically. In this embodiment, the vertical rod 31 is a telescopic rod to adjust the height of the tension rod 32. The vertical rod 31 includes a first vertical rod 311 and a second vertical rod 312. The first vertical rod 311 and the second vertical rod 312 are fixedly connected to each other. The first vertical rod 311 is detachably connected to the workbench 1, and the second vertical rod 312 is fixedly connected to the tension rod 32. There is a height difference between the two tension rods 32.

[0036] The first vertical rod 311 is detachably connected to the workbench 1. Workers can place the coil 4 on the work area of the workbench 1 and then connect the vertical rod 31 to the workbench 1. This reduces interference from the tensioning assembly 3 when placing the coil 4. In this embodiment, the first vertical rod 311 has a threaded section at its end, and the workbench 1 has a mounting hole for the first vertical rod 311 to threadably connect. The first vertical rod 311 is then threadedly secured to the workbench 1. In other embodiments, the first vertical rod 311 can be plugged into the mounting platform, with the plug-in end of the first vertical rod 311 having a non-circular interface to minimize rotation of the first vertical rod 311.

[0037] Reference Figure 1The tensioning rods 32 are arranged horizontally. After the unwinding of the coil 4, the surface material 5 is sequentially wound around a plurality of tensioning rods 32 before entering the feed mechanism of the plastic pelletizer. In this embodiment, a height difference is provided between the tensioning rods 32 of the two tensioning assemblies 3 to enhance the tensioning effect of the tensioning mechanism on the surface material 5, ensuring smooth and even delivery of the surface material 5 to the plastic pelletizer.

[0038] Reference Figure 1 and Figure 2 The first rubber sheet 33 is bonded to the outer periphery of the tensioning rod 32 and is designed to abut against the surface material 5. The surface material 5 is wound around the outer periphery of the tensioning rod 32 and abuts against the first rubber sheet 33. This allows the friction between the surface material 5 and the tensioning rod 32 to enhance the tensioning effect of the tensioning rod 32 on the surface material 5. Two limiting sleeves 34 are mounted on the tensioning rod 32, with a gap between them to accommodate the surface material 5. Each limiting sleeve 34 has a gap for a limiting bolt 35, which abuts against the first rubber sheet 33 to secure it. The limiting sleeves 34 and limiting bolt 35 work together to restrict the position of the surface material 5, reducing slippage on the tensioning rod 32 and improving the stability of the surface material 5 during transport. The distance between the two limiting sleeves 34 can be determined based on the width of the surface material 5, thereby increasing the usability of the feeding device.

[0039] The implementation principle of a feeding device for plastic granulation in the embodiment of the present application is as follows:

[0040] Reference Figure 1 and Figure 2 After the surface material 5 is unwound from the coil 4, it is sequentially wound around a plurality of tensioning rods 32 before entering the feeding mechanism of the plastic granulator. When the feeding mechanism of the plastic granulator pulls the surface material 5, the plurality of tensioning rods 32 have a tensioning effect on the surface material 5, thereby reducing the disturbance of the surface material 5 during transportation, so that the surface material 5 is smoothly and evenly transported to the plastic granulator, thereby improving the uniformity of the feeding of the plastic granulator and the uniformity of the finished plastic granules.

[0041] Reference Figure 1 and Figure 2 Moreover, the vertical rod 31 is a telescopic rod, so that the staff can flexibly adjust the length of the vertical rod 31 by adjusting the length of the overlapping part between the first vertical rod 311 and the second vertical rod 312; so as to improve the tensioning effect of the tensioning rod 32 on the face material 5.

[0042] Example 2

[0043] The difference between this embodiment 2 and embodiment 1 is that:

[0044] Reference Figure 3 and Figure 4The feeding device also includes a cart handle 6, a universal wheel 7 and a fixing assembly 8; several universal wheels 7 are fixed at intervals on the bottom of the workbench 1, and the fixing assembly 8 is fixed on the workbench 1. The fixing assembly 8 is used to temporarily fix the workbench 1.

[0045] Reference Figure 3 and Figure 4 The fixing assembly 8 includes a fixing sleeve 81, a screw 82, a handwheel 83, an abutment plate 84, and a second rubber sheet 85. The fixing sleeve 81 is fixed to the workbench 1 and is arranged vertically. The screw 82 is threadedly connected to the fixing sleeve 81. The abutment plate 84 is arranged horizontally and is fixed to the end of the screw 82 close to the ground. The handwheel 83 is fixed to the end of the screw 82 away from the ground. The handwheel 83 rotates to drive the abutment plate 84 to abut the ground. The second rubber sheet 85 is bonded to the side of the abutment plate 84 away from the screw 82 and abuts the ground.

[0046] The implementation principle of a feeding device for plastic granulation in the embodiment of the present application is as follows:

[0047] Reference Figure 3 and Figure 4 By setting a universal wheel 7 at the bottom of the workbench 1, it is convenient for the staff to transport the coil 4 and move the coil 4 to the designated feeding position; when the staff moves the coil 4 to the designated position, the staff rotates the hand wheel 83 to make the abutment plate 84 abut against the ground, thereby fixing the feeding device, thereby improving the uniformity of the surface material 5 delivered to the plastic granulator.

[0048] By arranging a second rubber sheet 85 at the bottom of the abutment plate 84, the elastic deformation of the second rubber sheet 85 and the greater friction between the second rubber sheet 85 and the ground are utilized to improve the connection strength between the feeding device and the ground, reduce the movement of the feeding device, and further improve the stability of the surface material 5 transportation.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
