Description

Technical Field

[0001] The utility model relates to the technical field of feeding of injection molding machines, and particularly relates to a centralized feeding device for injection molding machines. Background Art

[0002] Injection molding machines are key equipment for producing plastic products. These machines heat plastic materials to melt them and then inject the molten plastic into molds under high pressure to form the desired shapes. Injection molding machines are widely used in various industries, including automotive, electronics, medical, and consumer goods manufacturing.

[0003] In the operation of injection molding machines, a centralized feeding device is an important auxiliary equipment. It is mainly used to transport plastic particles from the storage area to the hopper of the injection molding machine.

[0004] However, the existing feeding devices for injection molding machines are prone to cause plastic particles to absorb moisture due to poor air permeability after storing plastic particles for a long time. This moisture absorption phenomenon will not only affect the processing performance of plastics but may also lead to a decline in product quality. Therefore, solving the moisture problem of the feeding device for injection molding machines is crucial for improving the production efficiency and product quality of injection molding machines. Summary of the Utility Model

[0005] In view of this, the utility model provides a centralized feeding device for injection molding machines, which can avoid the dampness of plastic particles caused by poor air circulation.

[0006] To solve the above technical problems, the utility model provides a centralized feeding device for injection molding machines, including a storage barrel. A plurality of air vents are arranged in the middle of the storage barrel in an array around the middle of the storage barrel. An outlet is arranged at the bottom of the storage barrel. Brackets are fixedly connected to the middle of the outlet and the top of the storage barrel respectively. A rotating column is rotatably connected to the middle between the two brackets. A plurality of stirring ribs are fixedly connected to the middle of the rotating column in an annular array around the rotating column, which can not only ensure air circulation but also keep the plastic particles dry, effectively avoiding the dampness of plastic particles caused by poor air circulation.

[0007] A housing is fixedly connected to the middle of the storage barrel. A plurality of notches are arranged in the middle of the housing in an array around the storage barrel; even if external air can smoothly enter the interior of the storage barrel through the air vents, while protecting the air vents from intrusion of external impurities and dust.

[0008] A ventilation component is arranged at the top of the housing. The ventilation component includes an exhaust fan fixedly connected to the center of the top of the housing. The exhaust fan is located directly above the storage barrel; that is, it can effectively extract the internal air.

[0009] The ventilation component further includes a collection shell fixedly connected to the top of the housing. A dust outlet is arranged on one side of the collection shell; that is, it is convenient to clean the dust and keep the particles clean.

[0010] The center of the discharge port is fixedly connected with a collection tank, and the bottom of the collection tank is fixedly connected with a discharge pipe; this ensures the smooth discharge of particles.

[0011] An installation groove is opened at the bottom of the housing, a support ring is fixedly connected to the middle of the installation groove, and the middle of the discharge pipe is fixedly connected to the middle of the support ring; this increases the stability of the discharge pipe.

[0012] A feed pipe is connected in series between the middle of the housing and the middle of the storage barrel; this enables new particles to flow in smoothly.

[0013] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0014] 1. The stirring effect helps the air circulation between plastic particles, reduces the possibility of plastic particles absorbing moisture, and the air vent allows external air to enter the interior of the storage barrel and contact the particles, thereby reducing the humidity of the particles. This can not only ensure air circulation but also keep the plastic particles dry, effectively avoiding the dampness of plastic particles caused by poor air circulation.

[0015] 2. The stirring effect helps to break up possible particle agglomerates, ensures the fluidity of plastic particles, and helps to evenly convey the plastic particles in the storage barrel to the discharge port.

[0016] 3. When the exhaust fan operates, it extracts the air inside the storage barrel, thereby creating a negative pressure inside the storage barrel. This negative pressure helps to further promote the entry of external air through the air vent into the storage barrel, enhancing the internal and external air circulation and reducing the humidity of plastic particles.

[0017] 4. Dust and impurities will slide along the inner wall of the collection shell towards the dust removal port, which is convenient for cleaning. This can prevent dust and impurities from re-entering the interior of the storage barrel and ensure the cleanliness of plastic particles. Description of the Drawings

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will combine the attached drawings of the embodiments of the present utility model Figures 1-4 to clearly and completely describe the technical solutions of the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the present utility model.

[0026] As Figures 1-4 shown: This embodiment provides an injection molding machine centralized feeding device, including a storage bucket. A plurality of ventilation ports are arranged in the middle of the storage bucket in an array around the middle of the storage bucket. A discharge port is opened at the bottom of the storage bucket. Brackets are fixedly connected to the middle of the discharge port and the top of the storage bucket respectively. A rotating column is rotatably connected in the middle between the two brackets. A plurality of stirring ribs are fixedly connected to the middle of the rotating column in an annular array around the rotating column. The center of the top of the upper bracket is fixedly connected with a motor, and the output shaft of the motor is fixedly connected with the center of the top of the rotating column;

[0027] By controlling the operation of the motor, the rotating column can be driven to rotate, so that the stirring ribs stir the plastic particles in the storage bucket. This stirring effect helps the air circulation between the plastic particles, reduces the possibility of plastic particles absorbing moisture, and also helps to break the possible particle agglomerates, ensuring the fluidity of the plastic particles. At the same time, the stirring also helps to evenly transport the plastic particles in the storage bucket to the discharge port, ensuring uniform supply of injection plastic particles. In addition, the ventilation port allows external air to enter the inside of the storage bucket and contact the particles, thereby reducing the humidity of the particles, which can not only ensure air circulation but also keep the plastic particles dry. Driven by the motor, the rotation speed of the rotating column can be adjusted according to actual needs to adapt to the stirring requirements of different types of plastic particles;

[0028] The outer shell is as Figure 1 , 4 shown,

[0029] The middle of the storage bucket is fixedly connected with an outer shell. The central axis of the outer shell coincides with the central axis of the storage bucket. A plurality of notches are arranged in the middle of the outer shell in an array around the storage bucket;

[0030] Protect the air vents from the intrusion of external impurities and dust, and at the same time, it can also collect accidentally spilled plastic particles. The notch allows external air to smoothly enter the inside of the storage barrel through the air vents.

[0031] The ventilation component is as Figure 1 , 4 shown,

[0032] A ventilation component is provided at the top of the outer shell. The ventilation component includes an exhaust fan fixedly connected to the center of the top of the outer shell. The exhaust fan is located directly above the storage barrel. The ventilation component also includes a collection shell fixedly connected to the top of the outer shell. An air outlet is provided on one side of the collection shell. One end of the collection shell close to the dust removal port is lower than the end far from the air outlet.

[0033] When the exhaust fan operates, it will extract the air inside the storage barrel, thereby creating a negative pressure inside the storage barrel. This negative pressure helps to further promote the entry of external air through the air vents into the storage barrel, enhance the internal and external air circulation, and reduce the humidity of the plastic particles. At the same time, the function of the exhaust fan also helps to discharge the heat and moisture that may be generated inside the storage barrel, maintaining a dry environment inside the storage barrel. During the process of the exhaust fan extracting air, the dust and impurities in the air will rise along the wind direction and enter the collection shell. The inclined design of the collection shell makes the dust and impurities slide along the inner wall of the collection shell towards the dust removal port, facilitating cleaning. In this way, it can prevent the dust and impurities from re-entering the inside of the storage barrel and ensure the cleanliness of the plastic particles.

[0034] The collection trough is as Figure 2 shown,

[0035] A collection trough is fixedly connected to the center of the discharge port. The diameter of the top opening of the collection trough is smaller than the diameter of the bottom opening of the collection trough. A discharge pipe is fixedly connected to the bottom of the collection trough.

[0036] Since a bracket is provided in the middle of the discharge port, which will block the discharge of some plastic particles, a collection trough is provided. The design of the collection trough can collect particles in a larger range, ensuring that enough particles are discharged through the discharge pipe for use.

[0037] The notch is as Figure 2 shown,

[0038] An installation groove is provided at the bottom of the outer shell. A support ring is fixedly connected to the middle of the installation groove. The middle of the discharge pipe is fixedly connected to the middle of the support ring.

[0039] When the discharge pipe is discharging, the middle of the discharge pipe is prone to shaking. The support ring can increase the support for the discharge pipe, enhance the stability of the discharge pipe, and prevent the discharge pipe from shaking or displacing during the discharging process.

[0040] The feed pipe is asFigure 3 As shown

[0041] In the middle of the outer shell and the middle of the storage bin, there is a feeding pipe connected in series;

[0042] Through the feeding pipe, new plastic particles can be input into the storage bin. The design of the feeding pipe enables the plastic particles to flow smoothly into the storage bin;

[0043] Working principle:

[0044] Drive the rotating column to rotate, drive the stirring ribs to stir the plastic particles in the storage bin, which helps the air circulation between the plastic particles, breaks the particle agglomerates, ensures fluidity, and evenly conveys the particles to the discharge port to ensure uniform supply of injection plastic particles. The air vents on the outer shell allow external air to enter the inside of the storage bin, contact with the particles, reduce humidity. The exhaust fan extracts the air inside the storage bin to form a negative pressure, promotes the external air to enter through the air vents, enhances air circulation, discharges heat and moisture, and maintains a dry environment. When the exhaust fan extracts air, it carries dust and impurities into the collection shell. The inclined design of the collection shell enables the dust and impurities to slide along the inner wall towards the dust removal port, facilitating cleaning, preventing the dust and impurities from re-entering the storage bin, and ensuring the cleanliness of the particles.

[0045] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0046] The above is the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
