Description

Technical Field

[0001] The utility model relates to the technical field of injection molding equipment, in particular to an injection molding equipment with a waste recycling function. Background Art

[0002] In the technical field of injection molding equipment, with the rapid development of industrial production, the injection molding process has become one of the important ways of plastic product production. However, in the injection molding production process, a large amount of waste will inevitably be generated. The injection molding machine with a waste recycling device can crush the waste for recycling, but the waste may stick to oil stains in the injection molding machine. If only the waste is crushed for recycling, it will cause secondary pollution. The recycling device in the prior art washes the crushed waste, but it does not consider that when the crushing device crushes the waste with oil stains, the crushing knives or crushing teeth will also stick to oil stains. If the crushing knives are not washed in time during the crushing process of the waste, it will cause the waste without sticking to oil stains to stick to oil stains during the crushing process, increasing the subsequent cleaning difficulty of the waste. Summary of the Utility Model

[0003] In order to solve the problems existing in the prior art, the utility model provides an injection molding equipment with a waste recycling function.

[0004] The technical solution adopted by the utility model is as follows:

[0024] Embodiment 1

[0025] As Figure 1As shown in the figure, an injection molding device with waste recycling function includes a machine platform 1, an injection molding machine 2 and a waste recycling mechanism 3. The injection molding machine 2 is arranged on the machine platform 1, and the waste recycling mechanism 3 is arranged inside the machine platform 1. The waste recycling mechanism 3 is located below the injection molding area 21 of the injection molding machine 2 so as to directly receive the waste generated during the injection molding process.

[0026] The waste recycling mechanism 3 includes a recycling box 30, a crushing component 31 and a cleaning component 32. The top of the recycling box 30 is open. The crushing component 31 is arranged on the top of the recycling box 30, and the cleaning component 32 is arranged below the crushing component 31. It can be understood that a water inlet 33 and a water outlet 34 are arranged on the side wall of the recycling box 30. The water inlet 33 is used to connect with a water inlet device, and the water outlet 34 is used to connect with a water outlet device. It can be understood that filter meshes are fixed on the water inlet 33 and the water outlet 34, and the aperture of the filter mesh is smaller than the size of the crushed material to prevent the material from flowing in and out of the recycling box along with the water flow.

[0027] It should be noted that both the water inlet device and the water outlet device are common devices. For example, a water pump is connected to the water inlet 33 of the recycling box 30 through a section of water pipe (such as a PVC pipe, a stainless steel pipe or a rubber pipe). A sealing joint (such as a flange, a threaded joint or a quick joint) will be used at the connection to ensure a tight connection and prevent water leakage. The water pump pumps the cleaning water source (such as clean water, a detergent solution, etc.) out of the water storage container, transports it through the water pipe into the recycling box 30, and cleans the waste. A drainage pump is installed near the water outlet 34 of the recycling box 30, and discharges the cleaned waste liquid through a drainage pipe (which can also be a PVC pipe, a stainless steel pipe or a rubber pipe). A sealing joint is also required at the connection to prevent water leakage. The drainage pump pumps the cleaned waste liquid out of the recycling box 30 and transports it through the drainage pipe to a wastewater treatment system or discharges it to a designated location.

[0028] As Figure 2 As shown in the figure, the crushing component 31 includes a first driving member 310, a rotating shaft 311 and crushing knives 312. The crushing knives 312 are arranged on the side wall of the rotating shaft 311. The first driving member 310 is arranged outside the recycling box 30. The output end of the first driving member 310 penetrates the side wall of the recycling box 30 and is connected to the rotating shaft 311. The rotating shaft 311 is rotatably connected to the inner wall of the box body of the recycling box 30. The cleaning component 32 includes a friction cleaning member 320, and the friction cleaning member 320 abuts against the crushing knives 312.

[0029] Among them, the first driving member 310 selects a motor as the driving source and is installed outside the recycling box 30. Its output end passes through the side wall of the recycling box 30 through a sealing device and is connected to the rotating shaft 311. The rotating shaft 311 passes through the center position of the top of the recycling box 30 and is rotatably connected to the inner wall of the recycling box 30 through a bearing and other rotating connectors. The crushing knives 312 are evenly distributed along the side wall of the rotating shaft 311. When the rotating shaft 311 rotates, the crushing knives 312 rotate accordingly to crush the waste materials falling into the recycling box 30. The friction cleaning member 320 can be designed as a brush or a scraper matching the shape of the crushing knife 312, installed inside the recycling box 30, and kept in pressure contact with the crushing knife 312. When the crushing knife 312 rotates, the friction cleaning member scrapes and cleans the oil stains on the crushing knife 312.

[0030] In this embodiment, the waste materials generated during the injection molding process fall into the recycling box 30 under the action of gravity. The first driving member 310 is started to drive the rotating shaft 311 and the crushing knives 312 to rotate, and the waste materials are crushed. During the crushing process, the friction cleaning member 320 continuously contacts the crushing knife 312 to clean the oil stains on the crushing knife 312 in real time. At the same time, the cleaning liquid can be injected into the recycling box 30 through the water inlet 33 to further improve the cleaning effect. The waste liquid after cleaning is discharged through the water outlet 34 for subsequent treatment.

[0031] As Figure 2 shown, in a possible implementation manner, the friction cleaning member 320 includes a fixing part 321 and a friction part 322. The fixing part 321 is connected to the friction part 322, and the friction part 322 abuts against the crushing knife 312. In a possible implementation manner, a plurality of the crushing knives 312 and the friction cleaning members 320 are provided. The friction parts 322 of the plurality of friction cleaning members 320 are arranged opposite to each other in pairs, and each crushing knife 312 is located between the two friction parts 322.

[0032] In this implementation manner, the fixing part 321 serves as the support and fixing part of the friction cleaning member 320. The fixing part 321 is usually made of a strong and durable material, such as stainless steel. Hard bristles are provided on the side wall of the friction part 322. The bristles abut against the crushing knife. The bristles can be densely arranged on the side wall of the friction part 322 to increase the contact area with the crushing knife 312 and improve the cleaning effect. A plurality of the crushing knives 312 and the friction cleaning members 320 are provided, and the friction parts 322 are arranged opposite to each other in pairs. Each crushing knife is located between the two friction parts. This layout ensures that each crushing knife can be evenly cleaned.

[0033] Embodiment Two

[0034] In a possible implementation manner, as Figure 3As shown, the cleaning assembly 32 further includes a filter member 323, which is connected to the inner wall of the recycling bin 30. The filter member 323 is disposed below the friction cleaning member 320, and the fixing portion 321 is connected to the filter member 323. The cleaning assembly 32 further includes a second driving member 324, a rotating member 325 and blades 326. The second driving member 324 is disposed at the bottom of the box body, the output end of the second driving member 324 is connected to the rotating member 325, and the blades 326 are disposed on the side wall of the rotating member 325. The blades 326 are used to form a vertical vortex in the recycling bin 30. The distance between the top of the blade 326 and the rotating member 325 is greater than the distance between the bottom of the blade 326 and the rotating member 325. Preferably, a plurality of the blades 326 are provided, and the plurality of blades 326 are arranged in a ring around the rotating member 325.

[0035] Among them, the filter member 323 is usually made of corrosion-resistant and easy-to-clean materials, such as a stainless steel filter plate. The size of the filter holes is determined according to the size of the materials to be separated to ensure that the crushed materials can pass through. The second driving member 324 can be selected from a motor or a hydraulic motor. The rotating member 325 can be a rotating shaft, which is connected to the output end of the second driving member 324. The blades 326 are designed to be inclined, so that the distance between the top and the rotating member 325 is greater than that of the bottom. Thus, a vertical vortex is formed during rotation. A plurality of blades 326 are provided, and they are usually arranged in a ring on the side wall of the rotating member 325 to produce a stronger vortex effect.

[0036] In this embodiment, the blades 326 are designed to be inclined, so that during rotation, the distance between the top and the rotating member 325 is greater than that of the bottom, thereby guiding the liquid to flow along the inclined direction of the blades. Due to the action of centrifugal force, the liquid will form a downward vortex around the rotating member 325. A plurality of blades 326 are arranged in a ring around the rotating member 325, further enhancing the intensity and stability of the vortex. The formation of the vortex causes strong mixing and agitation of the liquid and the crushed materials in the recycling bin 30. This agitation effect can effectively drive the crushed materials towards the bottom of the vortex, reducing the accumulation and retention of the materials above the filter member 323, improving the separation efficiency and falling speed of the materials. The vortex not only drives the movement of the materials, but also performs secondary cleaning on the crushed materials through the scouring and stirring action of the water flow. In the vortex, the material particles will continuously collide and rub against the surrounding water flow and other particles, thereby removing the residues and stains attached to the surface. This cleaning method is more thorough and effective than simple soaking or rinsing. It can be understood that after the cleaning is completed, the recycling bin can be pulled out of the machine to take out the cleaned materials.

[0037] The above-described embodiments merely represent the specific implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all fall within the protection scope of the present utility model.
