DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figures 1 to 6 As shown, the utility model provides a feeding device for the injection molding production of plastic pallets, comprising an extruding mechanism 1 and a feeding assembly 2, the feeding assembly 2 being fixedly connected to the top of the extruding mechanism 1, a material receiving assembly 3 being provided at the upper end of the feeding assembly 2, a blocking assembly 4 being provided in the middle of the feeding assembly 2 and the material receiving assembly 3, the blocking assembly 4 being fixedly connected to the feeding assembly 2, and the blocking assembly 4 being movably connected to the material receiving assembly 3;

[0029] The material receiving component 3 includes a main feeding hopper 31 which is mounted on the upper end of the feeding component 2. The bottom of the main feeding hopper 31 is connected to a number of evenly distributed vibration buffer springs 32. The two ends of the vibration buffer spring 32 are respectively connected to the feeding component 2 and the main feeding hopper 31. Due to the setting of the material receiving component 3, the continuous high-frequency vibration of the hopper can be achieved with the cooperation of the feeding component 2, so that the position of the discharge port at the lower end can be continuously changed, thereby reducing the probability of blockage, especially during the continuous reciprocating movement, which can make the raw materials accumulated inside move relative to the unblocking component 4, thereby achieving the effect of unblocking.

[0030] like Figure 4 and Figure 6 As shown, the main feeding hopper 31 includes a filter hopper 311 arranged in the auxiliary feeding hopper 22, and the top of the filter hopper 311 is fixedly connected to a debris removal magnetic ring 313, and the inner wall of the bottom of the debris removal magnetic ring 313 is smoothly connected to the inner wall of the top of the filter hopper 311, and the outer diameter of the bottom of the debris removal magnetic ring 313 is larger than the outer diameter of the top of the filter hopper 311; due to the setting of the filter hopper 311, dust and debris mixed in the raw materials falling along its inner wall can be filtered out, and the metal impurities in the raw materials can be absorbed by the debris removal magnetic ring 313, thereby effectively improving the product quality of the injection molding tray.

[0031] like Figure 4 and Figure 6When the bottle is fully opened, the bottle 31 is in the closed position, and the bottle 31 is in the closed position, so that the bottle 31 is kept in the closed position, and the bottle 31 is kept in the open position, so that the bottle 31 is kept in the open position.

[0032] like Figure 2 and Figure 3 The feeding assembly 2 shown includes a feeding barrel 21 fixedly connected to the top of the extrusion mechanism 1, and a feeding auxiliary bucket 22 is integrally formed on the top of the feeding barrel 21. The lower end of the feeding auxiliary bucket 22 is sleeved on the outside of the feeding main bucket 31, and the upper end of the feeding auxiliary bucket 22 is sleeved on the inside of the feeding main bucket 31.

[0033] like Figure 3 and Figure 4 The side of the feeding auxiliary bucket 22 is provided with a dust exhaust hole 23, and the interior of the feeding auxiliary bucket 22 is fixedly connected with a shrinkable rubber spacer 24 located at the bottom of the dust exhaust hole 23, and the inner side of the shrinkable rubber spacer 24 is fixedly connected to the lower end of the feeding main bucket 31; due to the setting of the shrinkable rubber spacer 24, it will not affect the vibration of the feeding main bucket 31, and can ensure that the dust leaked from the feeding main bucket 31 can flow out along the shrinkable rubber spacer 24 with the cooperation of the dust exhaust hole 23 and into the dust collecting hood 51.

[0034] like Figure 4 and Figure 5 The shown unblocking component 4 includes a material unblocking cone 41 that passes through the middle of the main feeding bucket 31. The outer surface of the material unblocking cone 41 is fixedly connected to a material unblocking paddle 42. The outer diameter of the material unblocking paddle 42 is smaller than the inner diameter of the main feeding bucket 31. Due to the setting of the material unblocking paddle 42, when the main feeding bucket 31 continuously vibrates up and down under the elastic force of the vibration buffer spring 32, the raw materials accumulated inside can move relative to the material unblocking paddle 42, that is, the material unblocking paddle 42 can scrape the accumulated raw materials, thereby achieving the effect of unblocking the blockage.

[0035] like Figure 4 and Figure 5The outer surface of the material dispersing cone 41 shown is also fixedly connected to a number of positioning frames 44 located below the main feeding bucket 31 and evenly distributed. The outer end of the positioning frame 44 is fixedly connected to a connecting frame 43. The lower end of the connecting frame 43 is fixedly connected to the inside of the feeding auxiliary bucket 22, and the upper end of the connecting frame 43 is movably connected to the inside of the lower end of the main feeding bucket 31.

[0036] like Figure 4 The outside of the feeding component 2 shown is connected with a dust collecting component 5 located below the dust exhaust hole 23. The dust collecting component 5 consists of a dust collecting hood 51 and a dust exhaust plate 52. The dust collecting hood 51 is fixedly connected to the outer surface of the feeding barrel 21, and the upper end of the dust collecting hood 51 extends to the top of the dust exhaust hole 23. The dust collecting hood 51 is tilted, and the dust exhaust plate 52 is fixedly connected to the lowest end of the side of the dust collecting hood 51; due to the setting of the dust exhaust plate 52, with the cooperation of the inclined structure of the dust collecting hood 51, the dust can slide along the bottom of the inner cavity of the dust collecting hood 51 to the dust exhaust plate 52 under the action of gravity, so that it is convenient for the staff to collect and process the dust at the dust exhaust plate 52.

[0037] The working principle and use process of this utility model:

[0038] The raw materials are poured into the main feeding bucket 31 and hit the main feeding bucket 31 under the action of gravity. With the support of the auxiliary feeding bucket 22, the elastic force of the vibration buffer spring 32 can make the main feeding bucket 31 vibrate frequently after being hit, so that the position of the discharge port at the lower end can be continuously changed, thereby effectively avoiding the situation where the discharge port is fixed and easily blocked.

[0039] Moreover, since the main feeding bucket 31 continuously vibrates up and down, the raw materials accumulated at the lower end discharge port and the blockage clearing component 4 can continuously move back and forth relative to each other, so that the accumulated raw materials can be effectively pushed forward by the scraping of the material clearing paddle 42, greatly reducing the probability of blockage;

[0040] Since the main feeding hopper 31 itself is a filter cover structure, when the raw materials fall onto the main feeding hopper 31, the dust mixed inside can fall into the auxiliary feeding hopper 22 through the main feeding hopper 31, and slide into the dust collecting hood 51 through the dust discharge hole 23 with the cooperation of the shrinking rubber spacer 24, and finally be discharged through the dust discharge plate 52 for cleaning.

Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
