Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically to a plastic bucket injection molding machine. Background Technology

[0002] In the field of injection molding technology, the production efficiency and quality of plastic buckets have always been key concerns. Traditional plastic bucket injection molding machines often require manual collection and transport of the buckets after processing, which not only increases labor costs but can also lead to damage or contamination of the buckets due to improper operation.

[0003] According to a public disclosure of an injection molding machine (publication number: CN104890178A): the worktable is equipped with a feeding mechanism and several molding dies. The injection track is arranged along the direction of evenly spaced distribution of the molding dies. The feeding mechanism includes a base and an injection device that is movably mounted on the base. The strip material is placed on the feeding device and enters the barrel through the inlet. The injection drive device drives the screw to rotate. When the screw rotates, it bites the strip material and conveys it towards the injection nozzle. At the same time, friction is generated between the strip material, the screw, and the barrel. The friction drives the strip material on the feeding device to continue to enter the barrel through the inlet, thereby realizing automatic feeding of strip rubber material.

[0004] The aforementioned application achieved automatic feeding of strip rubber material by setting up a feeding mechanism and molding die, but did not solve the problem of automatic collection and transportation after plastic bucket processing, which increased labor costs and posed a danger. Therefore, we propose a plastic bucket injection molding machine. Utility Model Content

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-5 As shown, a plastic bucket injection molding machine according to an embodiment of the present invention is shown, including: a supporting base column 1, a processing panel 2 fixedly connected to one end of the supporting base column 1, an injection molding device 3 provided on the top of the processing panel 2, a control panel 4 provided on the top of the processing panel 2, and a transmission and collection device 5 provided on the top of the processing panel 2.

[0034] The transmission and collection device 5 includes a transmission box 501, which is fixedly connected to the bottom of the processing panel 2. A mounting plate 502 is fixedly connected to the side of the processing panel 2. A dual-output shaft motor 503 is fixedly connected to the bottom of the mounting plate 502. A drive gear 504 is fixedly connected to the output shaft of the dual-output shaft motor 503. A drive rotating shaft 505 is rotatably connected through the side of the transmission box 501. A driven rotating shaft 506 is rotatably connected through the side of the transmission box 501. A conveyor belt 507 is provided on the circumferential surface of the drive rotating shaft 505. The driven rotating shaft 506 and the drive rotating shaft 505 are connected by transmission through the conveyor belt 507. A driven gear 508 is fixedly connected to one end of the drive rotating shaft 505. A feeding trough 509 is opened on the top of the processing panel 2. An anti-slip pad 510 is fixedly connected to the circumferential surface of the conveyor belt 507. A collection box 511 is fixedly connected to the side of the transmission box 501. A protective box 512 is fixedly connected to the side of the transmission box 501.

[0035] In some examples, a buffer spring 6 is fixedly connected to the inner side of the feed chute 509, and a buffer plate 7 is fixedly connected to the end of the buffer spring 6 away from the processing panel 2. Its function is to reduce the impact force when the material falls, avoid damage, ensure smooth transmission, and improve production efficiency.

[0036] There are four buffer springs 6, arranged in pairs and symmetrically distributed along the vertical central axis of the material feeding groove 509. There are two buffer plates 7, also symmetrically distributed along the vertical central axis of the material feeding groove 509. Their function is to further disperse the impact force of the material, optimize the buffering effect, ensure that the material falls evenly, and improve the molding quality.

[0037] The driving gear 504 and the driven gear 508 mesh with each other. The driving gear 504 has more teeth than the driven gear 508. Its function is to increase the transmission ratio, improve the transmission efficiency, ensure stable material conveying, reduce energy consumption, and extend the service life of the equipment.

[0038] The circumferential surface of the output shaft of the dual-output shaft motor 503 penetrates the protective box 512, and the circumferential surface of the active rotating shaft 505 also penetrates the protective box 512. The active gear 504 and the driven gear 508 are located inside the protective box 512. Their function is to effectively isolate external impurities, prevent gear wear, ensure stable operation of the transmission system, improve the overall durability of the equipment, and ensure continuous and efficient production.

[0039] For example, such as Figures 1-5 As shown, the detailed working principle is as follows: During the production of plastic buckets, the raw material is first heated and injected into the mold through the injection molding device 3. The mold is located on top of the processing panel 2. The injection molding device 3 precisely controls the injection volume and temperature of the raw material to ensure the molding quality of the plastic buckets. Once the plastic buckets cool and solidify in the mold, the mold is opened, and they are guided onto the conveyor belt 507 through the discharge chute 509. When the plastic buckets fall from the mold and impact the buffer plate 7, the buffer spring 6 absorbs most of the impact force, preventing damage to the plastic buckets. Subsequently, the plastic buckets fall smoothly onto the conveyor belt 507 under the guidance of the buffer plate 7. The conveyor belt 507 is connected by a drive shaft 505 and a driven shaft 506. The drive shaft 505 is driven to rotate by a dual-output shaft motor 503, thereby driving the conveyor belt 507 to continuously circulate. Since the number of teeth of the driving gear 504 is greater than that of the driven gear 508, the transmission ratio is increased, enabling the conveyor belt 507 to transport the plastic buckets at a stable speed, further improving production efficiency, and finally transporting them into the collection box 511.

[0040] like Figures 1-5The image shows a plastic bucket injection molding machine according to another embodiment of the present invention, including a spray cooling device 8. The spray cooling device 8 includes a water storage plate 801, which is fixedly connected to the bottom of a transfer box 501. A water suction pipe 802 is fixedly connected through and to the side of the water storage plate 801. A water pump 803 is fixedly connected to one end of a dual-shaft motor 503 away from the drive gear 504. The end of the water suction pipe 802 away from the water storage plate 801 is fixedly connected through and to the water pump 803. A drain pipe 804 is fixedly connected to the side of the water pump 803. A spray plate 805 is fixedly connected to the end of the drain pipe 804 away from the water pump 803. A filter box 806 is fixedly connected to the circumference of the water pump 802. A filter disc 807 is inserted into the top of the filter box 806. A through hole 808 is opened at the bottom of the transfer box 501. Its function is to draw water from the water storage plate 801 through the water pump 803 to effectively cool down the plastic bucket after injection molding, prevent high temperature deformation, and ensure stable product quality.

[0041] In some examples, a primary filter plate 11 is fixedly connected to the side of the water storage plate 801, a water guide plate 12 is fixedly connected to the bottom of the water storage plate 801, and a regulating valve 13 is fixedly connected through the circumference of the water pumping pipe 802. Its function is to regulate the water flow rate, ensure uniform cooling, prevent local overcooling or overheating, further optimize product quality, and extend the service life of the equipment.

[0042] The side section of the water guide plate 12 is set as an inclined plane, and the spray column of the spray plate 805 penetrates the side of the transmission box 501. Its function is to guide the water flow to gather in one place, so that the water pump 803 can better draw water to ensure uniform cooling of the plastic bucket, improve product consistency and durability.

[0043] The interior of the pumping pipe 802 is connected to the interior of the drain pipe 804. Several round holes are opened on the side of the primary filter plate 11. Its function is to filter large particles of impurities, prevent blockage of the water pump 803, ensure smooth water flow, further ensure the stable operation of the cooling system, and improve the overall production efficiency.

[0044] The spray plate 805 is located above the conveyor belt 507. The side cross section of the spray plate 805 is set in a U-shape. Its function is to make the sprayed water flow form a fan-shaped coverage, increase the contact area, improve the cooling efficiency, and at the same time avoid water droplet splashing, ensure a dry working environment, and improve operational safety.

[0045] For example, such as 1~ Figure 5As shown, the spray cooling device 8 plays a crucial role in the operation of the plastic bucket injection molding machine. After the plastic buckets are injected, cooled, and solidified, they are removed from the mold and guided onto the conveyor belt 507 via the feed chute 509. At this time, the spray cooling device 8 starts working. The water pump 803 is started by the dual-output shaft motor 503, drawing cooling water from the water storage plate 801 through the water suction pipe 802. To ensure the cleanliness of the cooling water and prevent clogging of the water pump 803, the water suction pipe 802 undergoes preliminary filtration through the filter box 806 and filter disc 807 to remove large particulate impurities. Subsequently, the filtered cooling water is transported to the drain pipe 804. The drain pipe 804 guides the cooling water to the spray plate 805. Because the side section of the spray plate 805 is set in a U-shape, when the cooling water is sprayed out from the spray plate 805, it will form a fan-shaped coverage and be evenly sprayed on the surface of the plastic bucket. After spraying, the water returns to the water storage plate 801 through the through hole 808 to form a circulating cooling system.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
