Description

Technical Field

[0001] This invention relates to the technical field of injection molding machines, specifically to a vertical injection molding machine with a material receiving and conveying mechanism. Background Technology

[0002] An injection molding machine, also known as an injection molding machine or injection molding machine, is a molding equipment that uses plastic molds to make plastic products of various shapes from thermoplastic or thermosetting plastics.

[0003] According to patent application CN201922156083.4, an injection molding machine with a conveying mechanism is described. The machine includes a base, with braked rollers at each of the four corners of the base's bottom outer wall. A mounting box is bolted to the top outer wall of the base, and a control box is mounted on the top outer wall of the mounting box. An inspection door is located on one side of the mounting box's outer wall. The same conveying mechanism is mounted on both inner walls of the mounting box, and a guide plate is fixed to both inner walls of the mounting box via bearings. A groove is formed at the central axis of the top outer wall of the guide plate, and electric slide rails are bolted to both inner walls of the groove. A baffle is slidably connected to the inner walls of the two electric slide rails. This injection molding machine, by installing a weighing conveyor belt inside the mounting box, facilitates the sorting of defective products in conjunction with the guide plate and baffle. When the weighing conveyor belt reaches different weights, a geared motor drives the guide plate to tilt, and simultaneously, the baffle rises, allowing the injection molded parts to pass through the guide plate and be collected into a collection box.

[0004] Although the aforementioned injection molding machine can facilitate the sorting out of defective products by setting a weighing conveyor belt inside the mounting box, in conjunction with guide plates and baffles, the material receiving mechanism of the aforementioned injection molding machine is bulky, and workers need to manually place the injection-molded products into the mounting box. This results in workers having to frequently come into contact with high-temperature products, which can easily cause burns, and the products are easily damaged. Summary of the Invention

[0005] The present invention mainly provides a vertical injection molding machine with a material receiving and conveying mechanism to solve the technical problems mentioned in the background art.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0007] A vertical injection molding machine with a material receiving and conveying mechanism includes a disc injection molding machine, wherein a cooling device is provided on one side of the disc injection molding machine, and a material receiving device is provided at the top of the cooling device;

[0008] The cooling device includes a cold storage box installed on one side surface of the disc injection molding machine, an air outlet assembly installed inside the cold storage box, and a circulating feeding assembly sleeved outside the air outlet assembly. The discharge end of the circulating feeding assembly is connected to a lifting discharge assembly.

[0009] The lifting and unloading assembly includes a vibrating frame installed inside the cold storage box, a lifting and sorting component installed inside the vibrating frame, and a sealing component located outside the vibrating frame.

[0010] The circulating feeding assembly includes a first arc-shaped conveyor belt installed on the inner wall of the cold storage box, and a second arc-shaped conveyor belt located at the bottom end of the first arc-shaped conveyor belt and installed on the inner wall of the cold storage box. The discharge ends of the first and second arc-shaped conveyor belts are both connected to the inlet end of the lifting and sorting component.

[0011] Furthermore, the air outlet assembly includes an air duct installed inside the cold storage box and passing through the first arc-shaped conveyor belt and the second arc-shaped conveyor belt in sequence, an air outlet pipe inserted through the upper surface of the air duct, and an evaporator inserted through the bottom end of the air duct. The evaporator is connected to the refrigeration system so that the evaporator exchanges heat with the air inside the air duct, thereby causing cold air to be blown out from inside the air duct by means of an exhaust fan.

[0012] Furthermore, the air outlet assembly also includes multiple exhaust fans arranged equidistantly from top to bottom between the evaporator and the air outlet pipe, and multiple air outlet holes on the outer surface of the air duct. The cold air in the air duct is guided by the exhaust fans to flow out from the air outlet pipe, and the air in the cold storage box sinks when it is cooled and flows back into the air duct through the air outlet holes at the bottom of the air duct for heat exchange.

[0013] Furthermore, the lifting and sorting component includes a hydraulic cylinder installed at the bottom of the vibrating frame, a finished product discharge plate installed at the top of the hydraulic cylinder, support rods installed at the four corners of the upper surface of the finished product discharge plate, and defective product discharge plates installed on the upper surfaces of the multiple support rods. The hydraulic cylinder drives the finished product discharge plate to rise and fall. Since the finished product discharge plate and the defective product discharge plate are connected by support rods, the defective product discharge plate is also driven to rise and fall simultaneously.

[0014] Furthermore, both ends of the finished product discharge plate and the defective product discharge plate are provided with guide holes, which guide the movement of the connecting rod.

[0015] Furthermore, the lifting and sorting component also includes a cylinder installed on the upper surface of the air duct, a first pusher plate installed on the piston rod of the cylinder, and connecting rods passing through both ends of the first pusher plate near the piston rod of the cylinder. The connecting rods pass through the guide hole and are connected to a second pusher plate. The cylinder drives the first pusher plate to move horizontally, and the first pusher plate drives the second pusher plate to move horizontally through the connecting rods, so that the first pusher plate pushes the products off the defective product discharge plate.

[0016] Furthermore, the material handling device includes a bracket installed on the upper surface of the cold storage box, and a robotic arm installed on the upper surface of the bracket. The bracket provides support for the robotic arm, which grabs the product that has been injection molded in the disc injection molding machine and puts the product into the first feed port.

[0017] Furthermore, a spring is installed between the bottom surface of the vibration frame and the bottom inner wall of the cold storage box, and a vibration motor is installed on the lower surface of the vibration frame. The vibration frame uses the energy stored in the spring to prevent dry friction between the vibration frame and the cold storage box, which would affect the service life of the cold storage box and the vibration frame.

[0018] Furthermore, the upper surface of the cold storage box is provided with a first inlet, and the side surface of the cold storage box away from the disc injection molding machine is provided with a first outlet and a second outlet from top to bottom. The side shell of the cold storage box away from the disc injection molding machine is provided with a sealed cavity. The cold storage box guides the injection-molded product into the box through the first inlet, discharges unqualified products through the first outlet, and discharges qualified products through the second outlet.

[0019] Furthermore, the sealing component includes a first transfer roller rotatably connected to the inner wall of the cold storage box and located at the bottom of the first feed inlet, and a second transfer roller and a third transfer roller rotatably connected to the inner wall of the sealing cavity from top to bottom. The first transfer roller, the second transfer roller and the third transfer roller are connected by a sealing strip. The sealing strip has an opening. When the product does not enter the cold storage box, the sealing strip blocks the first feed inlet, the first discharge outlet and the second discharge outlet, thereby completing the sealing of the cold storage box and preventing the leakage of cold air inside the cold storage box.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] Firstly, this invention can guide qualified and unqualified products to be discharged from different outlets of the cold storage box to improve material collection efficiency. Specifically, when the weight of a product does not meet the requirements, the product is driven to fall onto the defective product discharge plate by the first arc-shaped conveyor belt. When the product meets the requirements, the finished product discharge plate and the defective product discharge plate are lowered by the hydraulic cylinder, so that the product after initial cooling falls onto the second arc-shaped conveyor belt. The first pusher plate is moved horizontally by the cylinder, and the first pusher plate moves horizontally by the connecting rod, so that the first pusher plate pushes the product on the defective product discharge plate to be discharged.

[0022] Secondly, this invention can selectively cool defective and qualified products, thereby improving material collection efficiency and guiding rapid product forming. Specifically, when defective products fall onto the defective product discharge plate, they are simply cooled by the cold air in the cold storage box. Qualified products are conveyed by the first arc-shaped conveyor belt and move around the air duct. During this process, the products are initially cooled by the cold air continuously blown out by the air duct. After the products are initially cooled, they fall onto the second arc-shaped conveyor belt and are cooled again by the second arc-shaped conveyor belt moving around the air duct.

[0023] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0033] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings, which illustrate several embodiments of the present invention. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.

[0034] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] For an example, please refer to the appendix. Figure 1-8 A vertical injection molding machine with a material receiving and conveying mechanism includes a disc injection molding machine 10, wherein a cooling device 20 is provided on one side of the disc injection molding machine 10, and a material receiving device 30 is provided at the top of the cooling device 20.

[0037] The cooling device 20 includes a cold storage box 21 installed on one side surface of the disc injection molding machine 10, an air outlet assembly 22 installed inside the cold storage box 21, and a circulating feeding assembly 23 sleeved on the outside of the air outlet assembly 22. The discharge end of the circulating feeding assembly 23 is connected to a lifting discharge assembly 24.

[0038] The lifting and discharging assembly 24 includes a vibrating frame 241 installed inside the cold storage box 21, a lifting and sorting component 242 installed inside the vibrating frame 241, and a sealing component 243 located outside the vibrating frame 241.

[0039] The circulating feeding assembly 23 includes a first arc-shaped conveyor belt 231 installed on the inner wall of the cold storage box 21, and a second arc-shaped conveyor belt 232 located at the bottom end of the first arc-shaped conveyor belt 231 and installed on the inner wall of the cold storage box 21. The discharge ends of the first arc-shaped conveyor belt 231 and the second arc-shaped conveyor belt 232 are both connected to the inlet end of the lifting and sorting component 242.

[0040] For details, please refer to the appendix. Figure 3 and 7 The air outlet assembly 22 includes a duct 221 installed inside the cold storage box 21 and passing through the first arc-shaped conveyor belt 231 and the second arc-shaped conveyor belt 232 in sequence, an air outlet pipe 222 inserted through the upper surface of the duct 221, and an evaporator 223 inserted through the bottom end of the duct 221. The air outlet assembly 22 also includes a plurality of exhaust fans 224 disposed between the evaporator 223 and the air outlet pipe 222 and equidistantly arranged from top to bottom, and a plurality of air outlet holes 225 disposed on the outer surface of the duct 221.

[0041] It should be noted that in this embodiment, the evaporator 223 is connected to the refrigeration system so that the evaporator 223 exchanges heat with the air inside the air duct 221, thereby causing the air duct 221 to blow out cold air by means of the exhaust fan 224. The cold air inside the air duct 221 flows into the cold storage box 21 through the air outlet pipe 222 to cool the product entering the cold storage box 21.

[0042] Furthermore, the cold air inside the duct 221 is guided by the exhaust fan 224 to flow out from the air outlet 222. The air in the cold storage box 21 sinks when it is cooled and flows back into the duct 221 through the air outlet 225 at the bottom of the duct 221 for heat exchange. It then rises again through the exhaust fan 224 to form a cycle, thereby improving the utilization rate of the cold air.

[0043] For details, please refer to the appendix. Figure 4 , 56. The lifting and sorting component 242 includes a hydraulic cylinder 2421 installed at the bottom of the vibrating frame 241, a finished product discharge plate 2422 installed at the top of the hydraulic cylinder 2421, support rods 2423 installed at the four corners of the upper surface of the finished product discharge plate 2422, and defective product discharge plates 2424 installed on the upper surfaces of the multiple support rods 2423. Both ends of the finished product discharge plate 2422 and the defective product discharge plate 2424 are provided with guide holes 2425. The lifting and sorting component 242 also includes a cylinder 2426 installed on the upper surface of the air duct 221, and a first pusher plate 2427 installed on the piston rod of the cylinder 2426. Both ends of the first pusher plate 2427 near the piston rod of the cylinder 2426 are provided with connecting rods 2428. The connecting rods 2428 pass through the guide holes 2425 and are connected to a second pusher plate 2429.

[0044] It should be noted that in this embodiment, the finished product discharge plate 2422 is raised and lowered by the hydraulic cylinder 2421. Since the finished product discharge plate 2422 and the defective product discharge plate 2424 are connected by the support rod 2423, the defective product discharge plate 2424 is raised and lowered at the same time, and then the finished product discharge plate 2422 and the defective product discharge plate 2424 descend at the same time.

[0045] Furthermore, the finished product discharge plate 2422 and the defective product discharge plate 2424 guide the movement of the connecting rod 2428 through the guide hole 2425 on them;

[0046] Furthermore, the cylinder 2426 drives the first pusher plate 2427 to move horizontally, and the first pusher plate 2427 drives the second pusher plate 2429 to move horizontally via the connecting rod 2428, so that the first pusher plate 2427 pushes the product on the defective product discharge plate 2424 out, and the second pusher plate 2429 drives the product on the second pusher plate 2429 out.

[0047] For details, please refer to the appendix. Figure 1 , 2 5. The material handling device 30 includes a bracket 31 installed on the upper surface of the cold storage box 21, and a robot arm 32 installed on the upper surface of the bracket 31. A spring 2411 is installed between the bottom surface of the vibration frame 241 and the bottom inner wall of the cold storage box 21. A vibration motor 2412 is installed on the lower surface of the vibration frame 241.

[0048] It should be noted that in this embodiment, the support 31 provides support for the robot arm 32, the robot arm 32 grabs the product that has been injected into the disc injection molding machine 10 and puts the product into the first feed port 211;

[0049] Furthermore, the vibrating frame 241 generates vibration through the vibrating motor 2412. The vibration accelerates and guides the products on the finished product discharge plate 2422 and the defective product discharge plate 2424 to be discharged. The vibrating frame 241 stores energy through the spring 2411, thereby preventing dry friction between the vibrating frame 241 and the cold storage box 21, which would affect the service life of the cold storage box 21 and the vibrating frame 241.

[0050] For details, please refer to the appendix. Figure 5 and 8 The upper surface of the cold storage box 21 is provided with a first feed inlet 211. The side surface of the cold storage box 21 away from the disc injection molding machine 10 is provided with a first discharge outlet 212 and a second discharge outlet 213 from top to bottom. The side shell of the cold storage box 21 away from the disc injection molding machine 10 is provided with a sealing cavity 214. The sealing component 243 includes a first transmission roller 2431 rotatably connected to the inner wall of the cold storage box 21 and located at the bottom end of the first feed inlet 211, and a second transmission roller 2432 and a third transmission roller 2433 rotatably connected to the inner wall of the sealing cavity 214 from top to bottom. The first transmission roller 2431, the second transmission roller 2432 and the third transmission roller 2433 are connected by a sealing strip 2434, and the sealing strip 2434 is provided with an opening 2435.

[0051] It should be noted that in this embodiment, the cold storage box 21 guides the injection-molded product into the first inlet 211, discharges unqualified products through the first outlet 212, and discharges qualified products through the second outlet 213.

[0052] Furthermore, the rotation of the motor is controlled by a photoelectric switch, which drives the first transmission roller 2431 connected to its output shaft to rotate. Since the first transmission roller 2431, the second transmission roller 2432 and the third transmission roller 2433 are connected by a sealing strip 2434, the sealing strip 2434 is moved until the opening 2435 on the sealing strip 2434 is aligned with the first feed port 211, the first discharge port 212 and the second discharge port 213, so that the product can enter the cold storage box 21. When the product does not enter the cold storage box 21, the sealing strip 2434 blocks the first feed port 211, the first discharge port 212 and the second discharge port 213, thereby completing the sealing of the cold storage box 21 and preventing the cold air inside the cold storage box 21 from leaking out.

[0053] The specific operation method of this invention is as follows:

[0054] After the disc injection molding machine 10 completes the injection molding of the product, the robotic arm 32 grabs the product that has been injected into the disc injection molding machine 10 and puts the product into the first feed port 211. The product falls through the first feed port 211 onto the first arc-shaped conveyor belt 231 in the cold storage box 21. The first arc-shaped conveyor belt 231 weighs the product through a weighing sensor of model DNA4. The weighing sensor transmits an electrical signal with the weight information to the PLC controller connected to it. The PLC controller then judges whether the weight of the product meets the requirements. When the weight of the product does not meet the requirements, the PLC controller controls the first arc-shaped conveyor belt 231, which is electrically connected to it, to drive the product to fall onto the defective product discharge plate 2424. The cylinder 2426 drives the first pusher plate 2427 to move horizontally. The first pusher plate 2427 drives the second pusher plate 2429 to move horizontally through the connecting rod 2428, so that the first pusher plate 2427 pushes the product on the defective product discharge plate 2424 out.

[0055] When the product meets the requirements, it is moved around the air duct 221 by the first arc-shaped conveyor belt 231. During this process, the product is initially cooled by the cold air continuously blown out by the air duct 221. After cooling, the product falls onto the first pusher plate 2427. The finished product discharge plate 2422 is lowered by the hydraulic cylinder 2421. Since the finished product discharge plate 2422 and the defective product discharge plate 2424 are connected by the support rod 2423, the defective product discharge plate 2424 is lowered at the same time. The finished product discharge plate 2422 and the defective product discharge plate 2424 are lowered at the same time until the defective product discharge plate 2424 is lowered to the plane of the second arc-shaped conveyor belt 232. Since the finished product discharge plate 2422 and the defective product discharge plate 2424 are both inclined, the product that has been initially cooled falls onto the second arc-shaped conveyor belt 232. Driven by the second arc-shaped conveyor belt 232, the product is cooled again around the air duct 221.

[0056] After cooling again, the product falls onto the defective product discharge plate 2424 as the defective product discharge plate 2424 descends. The cylinder 2426 drives the first pusher plate 2427 to move horizontally. The first pusher plate 2427 drives the second pusher plate 2429 to move horizontally via the connecting rod 2428. The second pusher plate 2429 then discharges the product from its plate.

[0057] The present invention has been described by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
