Description

Technical Field

[0001] This utility model relates to the field of modified nylon chip processing technology, specifically to an injection molding machine unloading mechanism for preparing modified nylon chips. Background Technology

[0002] In the preparation process of modified nylon chips, the injection molding machine is a core piece of equipment, and the quality of its unloading process directly affects the continuity of production and product quality. In particular, the proper handling of the remaining material in the hopper after each production task is an important part that cannot be ignored in the entire production process.

[0003] Chinese Patent Application No. 202322301309.1 discloses an injection molding machine unloading device, including a feeding cylinder. Below the feeding cylinder are a transverse movement device, a rotation device, and a tilting device. The tilting device includes a mounting plate, a first mounting plate, a second mounting plate, and a tilting cylinder. The first mounting plate is disposed on the transverse movement device, and the second mounting plate is disposed on one side of the first mounting plate. The mounting plate is hinged to the upper surface of the first mounting plate. A first connecting seat is disposed on one side of the second mounting plate, and a second connecting seat is disposed on the lower surface of the mounting plate. In this utility model, a transverse movement device is provided. When unloading is required, the transverse movement device can drive the extruder nozzle away from the injection molding machine preset on one side, facilitating unloading through the extruder nozzle.

[0004] The aforementioned patents require the entire feed cylinder and loading cylinder of the injection molding machine to move the remaining material in the loading cylinder. Frequent movement causes the connecting parts, such as pipe interfaces and mechanical connectors, to be subjected to significant stress over a long period. The seals at the pipe interfaces are prone to wear during repeated displacement, leading to material leakage. The mechanical connectors may become loose, deformed, or even broken due to uneven stress over a long period. This not only increases the failure rate of the equipment but also significantly shortens its service life and increases maintenance and replacement costs. During the movement, any operational errors, such as equipment imbalance or collisions, may cause material spillage or even serious safety accidents, threatening the lives of operators. Therefore, we propose a novel unloading mechanism for injection molding machines used in the preparation of modified nylon chips. Utility Model Content

[0005] This utility model provides the following technical solution: a discharge mechanism for an injection molding machine used in the preparation of modified nylon chips, comprising a discharge housing, a feed pipe fixedly installed at the upper end of the discharge housing, and a guide pipe and a discharge pipe symmetrically arranged fixedly installed at the bottom end of the discharge housing. Vibration elements are provided on the outer surfaces of both the guide pipe and the discharge pipe. A reversing ball is provided inside the discharge housing, and a through-flow channel is opened inside the reversing ball. A rotating handle is rotatably connected to the bottom end of the discharge housing, and the upper end of the rotating handle extends into the interior of the discharge housing and is fixedly installed at the bottom end of the reversing ball. A locking element is provided at the bottom end of the rotating handle.

[0006] Preferably, the locking component includes a fixing rod, which is fixedly installed at the bottom end of the unloading housing. A sleeve is fitted on the outer surface of the fixing rod, and a connecting spring is fitted on the outer surface of the fixing rod. The two ends of the connecting spring are respectively fixedly installed at the bottom end of the unloading housing and the upper end of the sleeve.

A return spring is fixedly mounted on the inner sidewall of the mounting housing. A U-shaped plate is fixedly mounted on one end of the return spring. The cross-section of the U-shaped plate is U-shaped. A striking block is fixedly mounted on the inner sidewall of the U-shaped plate. A movable component is provided at the upper end of the mounting housing.

[0008] Preferably, the movable component includes a through groove, which is formed at the upper end of the mounting housing. A half gear is provided in the groove, and a vibration motor is fixedly installed on the side end of the half gear. The vibration motor is fixedly installed at the upper end of the mounting housing.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-4As shown, this utility model provides a technical solution: a discharge mechanism for an injection molding machine used for preparing modified nylon chips, including a discharge housing 1, a feed pipe 4 fixedly installed at the upper end of the discharge housing 1, a guide pipe 5 and a discharge pipe 6 fixedly installed at the bottom end of the discharge housing 1 in a symmetrical arrangement, a vibrating element 9 provided on the outer surface of both the guide pipe 5 and the discharge pipe 6, a reversing ball 2 provided inside the discharge housing 1, a through flow channel 3 opened inside the reversing ball 2, a rotating handle 7 rotatably connected to the bottom end of the discharge housing 1, the upper end of the rotating handle 7 extending into the interior of the discharge housing 1 and fixedly installed at the bottom end of the reversing ball 2, and a locking element 8 provided at the bottom end of the rotating handle 7.

[0021] In an optional embodiment: the locking member 8 includes a fixing rod 802, which is fixedly installed at the bottom end of the unloading housing 1. A sleeve 803 is sleeved on the outer surface of the fixing rod 802, and a connecting spring 805 is sleeved on the outer surface of the fixing rod 802. The two ends of the connecting spring 805 are respectively fixedly installed at the bottom end of the unloading housing 1 and the upper end of the sleeve 803. A disc 801 is fixedly installed at the bottom end of the rotating handle 7. Two through-hole locking holes 806 are opened on the disc 801.

[0022] It should be noted that when the reversing ball 2 rotates, it is fixed by the locking part 8 to prevent it from rotating, ensuring that the flow channel 3 is connected to the upper end of the guide pipe 5 or the upper end of the discharge pipe 6, so that the material can flow out smoothly.

[0023] In an optional embodiment: the vibrating element 9 includes a mounting housing 901, which is fixedly mounted on the outer surface of the unloading pipe 6. A return spring 902 is fixedly mounted on the inner side wall of the mounting housing 901. A U-shaped plate 908 is fixedly mounted on one end of the return spring 902. The cross-section of the U-shaped plate 908 is U-shaped. A striking block 904 is fixedly mounted on the inner side wall of the U-shaped plate 908. A movable element is provided at the upper end of the mounting housing 901.

[0024] It should be noted that the vibrating element 9 is located near the bend of the guide pipe 5 or the discharge pipe 6. When the material flow direction changes abruptly, which may cause the material to accumulate, the vibrating element 9 impacts the outer wall of the discharge pipe 6 or the guide pipe 5, applying external force to the material at the bend, thereby disrupting the stability of the material accumulation and preventing the material from accumulating.

[0025] In an optional embodiment: the movable component includes a through groove 903, which is formed at the upper end of the mounting housing 901. A half gear 906 is provided in the groove 903. A vibration motor 905 is fixedly installed on the side end of the half gear 906. The vibration motor 905 is fixedly installed at the upper end of the mounting housing 901. A plurality of gear teeth 907 are fixedly installed at the upper end of the U-shaped plate 908. The plurality of gear teeth 907 mesh with the half gear 906.

[0026] It should be noted that the rotation of the output end of the vibration motor 905 causes the output end of the half gear 906 to rotate. The half gear 906 meshes with multiple gear teeth 907 installed on the upper end of the U-shaped plate 908. Therefore, the rotation of the half gear 906 will cause the U-shaped plate 908 to rotate, thus achieving the purpose of striking.

[0027] In an optional embodiment: a lever 804 is fixedly installed on the upper end of the sleeve 803, and the lever 804 is sleeved on the outer surface of the lever 804.

[0028] It should be noted that when the lever 804 is moved upward, the sleeve 803 moves out of the locking hole 806 along with it, and the connecting spring 805 is compressed.

[0029] In an optional embodiment: a handle 10 is fixedly installed at the bottom end of the disk 801, and the longitudinal section of the handle 10 is U-shaped.

[0030] It should be noted that controlling the rotation of the handle 7 by turning the handle 10 is more convenient than operating the rotating disc 801.

[0031] In practical use, the working principle of this utility model is as follows:

[0032] During operation, the upper end of the feed pipe 4 is fixedly installed at the bottom end of the feeding cylinder, and the bottom end of the guide pipe 5 is fixedly installed at the upper end of the feeding cylinder. During injection molding, the bottom end of the flow channel 3 is connected to the upper end of the guide pipe 5, so that the material enters the feed pipe 4, then flows through the flow channel 3 into the guide pipe 5, and then into the feeding cylinder. When unloading, the bottom end of the unloading pipe 6 can be used to place the equipment for loading the remaining material. By holding the handle 10 and rotating the rotating handle 7 clockwise and counterclockwise, the rotating handle 7 rotates and drives the reversing ball 2 to rotate. After the reversing ball 2 rotates 180 degrees, the bottom end of the flow channel 3 is connected to the upper end of the unloading pipe 6, so that the material entering the feed pipe 4 flows into the unloading pipe 6. By changing the flow direction of the material, the purpose of unloading is achieved without moving the feeding cylinder and the feeding cylinder, which is simple and efficient.

[0033] Before rotating the handle 7, the lever 804 needs to be moved upward. When the lever 804 moves upward, it moves the sleeve 803 out of the locking hole 806 and causes the connecting spring 805 to compress. This allows the handle 7 to be rotated. During the rotation, the bottom end of the sleeve 803 is always in contact with the top end of the disc 801. When the other locking hole 806 rotates to the bottom end of the sleeve 803, the elastic force of the connecting spring 805 causes the sleeve 803 to be inserted into the lower locking hole 806, thus fixing the disc 801 and preventing it from continuing to rotate.

[0034] During the unloading process, when the material enters the bend of the unloading pipe 6 or the guide pipe 5, the sudden change in the material flow direction may cause material accumulation. At this time, the vibratory motor 905 is connected to an external power source. The output end of the vibratory motor 905 rotates, causing the half gear 906 to rotate. Since the half gear 906 is meshed with multiple gear teeth 907 below, when the half gear 906 rotates, the gear teeth 907 will move, compressing the return spring 902. When the gear teeth 907 move, they also bring the striking block 90... 4. The striking block 904 moves and strikes the outer wall of the discharge pipe 6 or the guide pipe 5, applying external force to the material at the bend and disrupting the stability of the material accumulation. When the half gear 906 separates from the gear tooth 907, the return spring 902 pushes the U-shaped plate 908 back to the initial position. When the half gear 906 and the gear tooth 907 mesh again, the process of pushing the U-shaped plate 908 to move is repeated. By repeating this cycle, the striking block 904 can continuously strike the guide pipe 5 or the discharge pipe 6.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
