The above utility model utilizes vibrating motors to prevent material jamming on the surface of the belt conveyor. Injection molding machines come in various shapes, and the required feeding direction and position vary. The aforementioned utility model is an integrated feeding device that cannot be adjusted according to the actual outlet position of the injection molding machine and the conveying direction after feeding. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an auxiliary conveying device for injection molding machines, comprising two sets of inclined conveyor frames at different heights and a curved conveyor frame fixedly installed between the inclined conveyor frames. The bottoms of both the inclined conveyor frames and the curved conveyor frame are supported by multiple sets of support frames. A drive motor for driving the inclined conveyor frame is fixedly installed on one side of each inclined conveyor frame. A cooling box is fixedly installed at the bottom of one set of inclined conveyor frames at the material discharge position of the injection molding machine.

[0005] The driving force of the motor ensures stable conveying of the material parts by the inclined conveyor. A cooling box, fixedly installed at the bottom of the inclined conveyor at the injection molding machine's discharge position, cools the molded material parts.

[0006] As a further preferred technical solution of this utility model, the inclined conveyor frame has multiple sets of mounting holes, and side mounting frames are welded and installed on both sides of the inclined conveyor frame. The side mounting frames have multiple sets of positioning holes. Two sets of protective frames are installed on the top of one set of the inclined conveyor frame. Multiple sets of insert plates are fixedly installed at the bottom of the protective frames, and the insert plates are installed through the mounting holes for limiting installation. Connecting frames are connected and installed on the sides of the insert plates. The connecting frames have multiple sets of mating holes located at the same position as the positioning holes, and the mating holes and the positioning holes are fixedly installed by bolts.

[0007] The protective frame can be disassembled and installed, facilitating the protection of materials during the unloading process.

[0008] As a further preferred technical solution of this utility model, multiple sets of rotating rollers are installed between the inclined conveyor frames via fixed bearings. Auxiliary drive rollers and driven rollers are respectively installed on both sides of each rotating roller. The rotating rollers and the driven rollers are connected by a driving pulley and a connecting pulley. A drive roller is installed on one side of each auxiliary drive roller, and meshing gears are fixedly installed on both the drive roller and the auxiliary drive roller. The meshing gears mesh with each other for transmission. The output end of the drive motor passes through the inclined conveyor frame and is rotatably connected to the drive roller.

[0009] The drive motor powers the drive roller, which, through the meshing gears, rotates the auxiliary transmission roller. This, in turn, causes the drive pulley on the auxiliary transmission roller to drive the connecting pulley, which in turn rotates the driven roller. This allows the inclined conveyor frame to effectively transport and feed materials.

[0010] As a further preferred technical solution of this utility model, the cooling box is provided with a cooling cavity inside. Multiple sets of positioning rings are fixedly installed on the inner walls of both sides of the cooling box. Two sets of limiting holes are provided on each positioning ring. A set of conveying pipes is installed through each positioning ring. The ends of the conveying pipes are respectively provided with an inlet and an outlet, and the inlet and outlet are fixed together by a fixing bracket.

[0011] The coolant is supplied by connecting to an external conveying pump at both the inlet and outlet ends. This cools the materials being transported on the top conveyor.

[0012] As a further preferred technical solution of this utility model, multiple sets of fan frames are fixedly installed at the bottom of the cooling box, and fans are fixedly installed inside the fan frames.

[0013] A fan blows through the top conveyor pipe, causing the cooling liquid circulating inside to further cool the material parts conveyed by the inclined conveyor frame, accelerating the cooling and shaping process. This prevents the material parts from being damaged or deformed due to impacts during transport.

[0014] As a further preferred technical solution of this utility model, two sets of guardrails are installed on the curved conveyor frame, and multiple sets of curved conveyor rollers are rotatably installed between the guardrails. A connecting frame is welded to both ends of each guardrail, and the curved conveyor frame and the inclined conveyor frame are fixedly installed together by the connecting frame and fixing bolts.

[0015] The two sets of inclined conveyor frames in different directions make it easy to adjust the position of the inclined conveyor frames according to different material feeding positions of the injection molding machine and the required material guiding direction. Furthermore, the connection and installation of the curved conveyor frame with the inclined conveyor frame facilitates the transportation of the injection-molded material parts.

[0016] Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. The system is connected to an external delivery pump at both the inlet and outlet ends to achieve effective coolant delivery. A fan blows through the top delivery pipe, promoting the circulation of coolant within the pipe to further cool the materials being transported via the inclined conveyor frame, thereby accelerating the cooling and shaping process. This prevents damage or deformation of the materials during transport due to impacts.

[0019] 2. Two sets of inclined conveyor frames in different directions allow for easy adjustment of their positions according to different material feeding positions and required material guiding directions on the injection molding machine. This adapts to various material feeding positions and guiding directions. Furthermore, the connection between the curved conveyor frame and the inclined conveyor frame facilitates the transport of molded parts. A set of three driving transmission structures—auxiliary drive rollers, drive rollers, and driven rollers—on one set of inclined conveyor frames enhances the driving effect on the injection molding material, thereby reducing the likelihood of it getting stuck on the surface of the inclined conveyor frame.

[0025] This specific embodiment is a material feeding auxiliary conveying device for injection molding machines.

[0026] The aforementioned utility model utilizes a vibration motor to prevent material from jamming on the surface of the belt conveyor. However, injection molding machines vary in shape, and the required feeding direction and position differ accordingly. The aforementioned utility model, being an integrated feeding device, cannot be adjusted according to the actual outlet position of the injection molding machine or the conveying direction after feeding.

[0027] Its structural diagram is as follows Figures 1-4 As shown. A material feeding auxiliary conveying device for an injection molding machine includes two sets of inclined conveyor frames 1 at different heights and a curved conveyor frame 3 fixedly installed between the inclined conveyor frames 1. The bottoms of both the inclined conveyor frames 1 and the curved conveyor frame 3 are supported by multiple sets of support frames 4. A drive motor 5 for driving the inclined conveyor frame 1 to convey materials is fixedly installed on one side of the inclined conveyor frame 1. Multiple sets of mounting holes 11 are provided on the inclined conveyor frame 1, and side mounting frames 12 are welded to both sides of the inclined conveyor frame 1. Multiple sets of positioning holes 13 are provided on the side mounting frames 12. Two sets of protective frames 6 are installed on the top of one set of inclined conveyor frames 1. Multiple sets of insert plates 61 are fixedly installed at the bottom of the protective frames 6, and the insert plates 61 are limited and installed through the mounting holes 11. Connecting frames 62 are connected and installed on the sides of the insert plates 61. Multiple sets of mating holes 63 are provided on the connecting frames 62, which are located at the same position as the positioning holes 13, and the mating holes 63 and the positioning holes 13 are fixedly installed by bolts. The protective frame 6 can be disassembled and installed, facilitating the protection of materials being transported during the unloading process.

[0028] Multiple sets of rotating rollers 57 are installed between inclined conveyor frames 1 via fixed bearings. Auxiliary drive rollers 51 and driven rollers 56 are installed on both sides of each rotating roller 57. The rotating rollers 57 and driven rollers 56 are connected by a drive pulley 54 and a connecting pulley 55. A drive roller 52 is installed on one side of the auxiliary drive roller 51, and meshing gears 53 are fixedly installed on both the drive roller 52 and the auxiliary drive roller 51. The meshing gears 53 mesh with each other for transmission. The output end of the drive motor 5 passes through the inclined conveyor frame 1 and is rotatably connected to the drive roller 52. The drive motor 5 drives the drive roller 52, and through the meshing gears 53, the drive roller 52 drives the auxiliary drive roller 51 to rotate, thereby causing the drive pulley 54 on the auxiliary drive roller 51 to drive the connecting pulley 55, which in turn drives the driven roller 56 to rotate. This allows the inclined conveyor frame 1 to achieve the effect of conveying and feeding materials. A cooling box 2 is fixedly installed at the bottom of one set of inclined conveyor frames 1 at the injection molding machine's discharge position. The cooling box 2 has a cooling chamber 23 inside. Multiple sets of positioning rings 24 are fixedly installed on the inner walls of both sides of the cooling tank 2. Two sets of limiting holes 25 are provided on each positioning ring 24. A set of conveying pipes 26 are installed through each positioning ring 24. The ends of the conveying pipes 26 are respectively provided with an inlet end 261 and an outlet end 262, which are fixedly positioned by a fixing bracket 27. The inlet end 261 and the outlet end 262 are connected to an external conveying pump to convey coolant, thereby cooling the materials conveyed on the top conveying device. Multiple sets of fan frames 21 are fixedly installed at the bottom of the cooling tank 2, and fans 22 are fixedly installed inside the fan frames 21. The fans 22 blow air through the top conveying pipes 26, causing the coolant circulating inside the conveying pipes 26 to provide auxiliary cooling for the materials conveyed by the inclined conveying frame 1, accelerating the cooling and shaping effect. This prevents the materials from being damaged or deformed during conveying. Two sets of guardrails 32 are installed on the curved conveyor frame 3, and multiple sets of curved conveyor rollers 31 are rotatably installed between the guardrails 32. A connecting frame 33 is welded to both ends of the guardrails 32, and the curved conveyor frame 3 and the inclined conveyor frame 1 are fixedly installed together by the connecting frame 33 and fixing bolts 34. The two sets of inclined conveyor frames 1 in different directions allow for easy adjustment of the position of the inclined conveyor frame 1 according to different material feeding positions and required material guiding directions of the injection molding machine. Furthermore, the docking installation of the curved conveyor frame 3 and the inclined conveyor frame 1 facilitates the conveying of the injection-molded material parts.

[0029] First, the conveying device is installed according to the material feeding position of the injection molding machine. It is connected to an external conveying pump via the inlet end 261 and outlet end 262 to convey coolant. During conveying, a fan 22 blows air through the top conveying pipe 26, causing the coolant circulating inside the pipe 26 to provide auxiliary cooling for the material parts conveyed by the inclined conveyor frame 1. The drive motor 5 is started, driving the drive roller 52. Through the meshing gear 53, the drive roller 52 drives the auxiliary transmission roller 51 to rotate, thereby causing the drive pulley 54 on the auxiliary transmission roller 51 to drive the connecting pulley 55, which in turn drives the driven roller 56 to rotate. This, combined with multiple sets of curved conveying rollers 31 installed on the curved conveyor frame 3, guides and transfers the molded material parts.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
