Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, specifically to an injection molding material conveying pipeline and a centralized material supply system. Background Technology

[0002] In modern injection molding systems, the continuous and stable delivery of plastic granules is a key factor in ensuring injection molding production efficiency and product consistency. In common centralized feeding systems for injection molding, plastic granules are typically delivered from a central feeding unit to the feed inlets of each injection molding machine in a dried state. To achieve directional movement and effective propulsion of the material within the conveying pipeline, screw conveyors are commonly used as the propulsion structure. This type of structure generates continuous thrust in the axial direction of the pipeline through the rotation of the helical blades, thereby driving the material forward steadily. It is suitable for production needs requiring moderate distances and continuous feeding rhythms.

[0003] However, in practical use, traditional screw conveyor mechanisms suffer from problems such as complex maintenance and high replacement costs. Because screw conveyors are usually integrally molded, they cannot be replaced modularly when local wear occurs; the entire conveying assembly must be replaced, resulting in long maintenance cycles and high economic costs. Utility Model Content

[0004] The purpose of this utility model is to provide an injection molding material conveying pipe and a centralized material supply system to solve the problems mentioned in the background art.

[0005] Firstly, this utility model provides an injection molding material conveying pipe, including a pipe body. A material propulsion mechanism is provided within the pipe body. The material propulsion mechanism includes: a pair of transmission rods, rotatably mounted at both ends of the pipe body, each transmission rod having a first toothed portion; a transmission belt, the side of the transmission belt facing the transmission rod having a second toothed portion, the first toothed portion meshing with the first toothed portion; and multiple transmission plates, the transmission plates being fixed at intervals to the back of the transmission belt opposite to the second toothed portion, and arranged sequentially along the transmission direction of the transmission belt. Through this solution, the multiple transmission plates on the transmission belt ensure that while the material is being conveyed, the transmission plates can be replaced individually during maintenance, eliminating the need to replace the entire material propulsion mechanism, thus improving maintenance efficiency and reducing maintenance costs.

[0006] Preferably, the transmission belt has a baffle on each of its two sides in the width direction, the baffle being used to prevent material from entering the inner side of the transmission belt.

[0007] Preferably, the transmission belt is provided with a plurality of slots at intervals along its transmission direction, each slot is provided with a first fitting part, and the transmission plate is provided with a second fitting part that cooperates with the first fitting part. Each transmission plate is fixed to the transmission belt through its second fitting part.

[0008] By setting baffles on both sides of the transmission belt in the width direction, materials can be prevented from entering the inner side of the transmission belt, thus preventing material jamming and improving the operational stability and service life of the material feeding mechanism.

[0009] Preferably, the tube body includes: a main body, which is located outside the material feeding mechanism and has an opening; and a side plate, which is located at the opening of the main body.

[0010] Secondly, this utility model provides a centralized material supply system, including the injection molding material conveying pipe described in any of the preceding claims. Attached Figure Description

[0022] Example

[0023] Please see Figure 1-6 As shown, this utility model provides an injection molding material conveying pipe, including a pipe body 1. A material propulsion mechanism 2 is provided inside the pipe body 1. The material propulsion mechanism 2 includes: a pair of transmission rods 201, a transmission belt 203, and multiple transmission plates 205. The transmission rods 201 are rotatably disposed at both ends of the pipe body 1. The transmission rods 201 are provided with a first tooth portion 202. The side of the transmission belt 203 facing the transmission rods 201 is provided with a second tooth portion 204. The first tooth portion 202 and the second tooth portion 204 are meshed and connected. The transmission plates 205 are fixed at intervals on the back side of the transmission belt 203 opposite to the second tooth portion 204 and are arranged sequentially along the transmission direction of the transmission belt 203.

[0024] In this embodiment, as Figure 4 As shown, the first tooth portion 202 is arranged along the width direction of the tube body 1; as Figure 3 As shown, the second toothed portion 204 is also arranged along the width direction of the tube body 1. One side of the transmission rod 201 is connected to a drive mechanism (e.g., a motor) to drive the transmission belt 203, thereby realizing the conveying of materials.

[0025] By using the above solution, setting multiple transmission plates 205 on the transmission belt 203 can ensure that the material is being transported while allowing the transmission plate 205 to be replaced individually during maintenance, without having to replace the entire material propulsion mechanism 2, thus improving maintenance efficiency and reducing maintenance costs.

[0026] The transmission belt 203 has a baffle 3 on each of its two sides in the width direction. The baffle 3 is used to prevent material from entering the inner side of the transmission belt 203.

[0027] In this embodiment, as Figure 2 and Figure 3 As shown, the baffle 3 includes connecting portions disposed on two sides of the transmission belt 203 in the width direction, and extension portions extending outward from the connecting portions. The extension portions extend away from the transmission belt 203 and extend along the centerline of the transmission belt 203 to prevent material from entering.

[0028] like Figure 2 and Figure 5 As shown, the transmission belt 203 is provided with a plurality of slots 4 at intervals along its transmission direction. Each slot 4 is provided with a first fitting part 5. The transmission plate 205 is provided with a second fitting part 6 that cooperates with the first fitting part 5. Each transmission plate 205 is fixed to the transmission belt 203 through its second fitting part 6.

[0029] In this embodiment, the first fitting part 5 is provided as a plurality of recessed structures and is arranged along the depth direction of the slot 4. The second fitting part 6 is a protruding structure with a number matching the recessed structures. The position of the protruding structure corresponds to the position of the recessed structure. The transmission plate 205 is fixed on the transmission belt 203 by fitting.

[0030] By setting baffles 3 on both sides of the transmission belt 203 in the width direction, materials can be blocked from entering the inner side of the transmission belt 203, preventing materials from causing jamming and improving the operational stability and service life of the material pushing mechanism 2.

[0031] The tube body 1 includes a main body 101 and a side plate 102. The main body 101 is located on the outside of the material pushing mechanism 2. The main body 101 has an opening 7. The side plate 102 is located at the opening 7 of the main body 101. By dividing the tube body 1 into two parts, the main body 101 and the side plate 102, it is convenient to disassemble and maintain the material pushing mechanism 2. At the same time, it can effectively prevent plastic particles from leaking from the joint between the main body 101 and the side plate 102 during the conveying process.

[0032] This invention also proposes a centralized material supply system, which includes the injection molding material conveying pipeline described in the above embodiment. The centralized material supply system further includes an injection molding machine 11, whose input end is equipped with a dehumidifying dryer 10. The dehumidifying dryer 10 introduces hot air through a negative pressure fan 9 to dry and dehumidify the injection molding granules. To further improve the cleanliness of the hot air, a dust collector 8 can be installed at the front end of the negative pressure fan 9 to filter impurities in the air, thereby ensuring the purity of the hot air.

[0033] The working principle of this utility model is as follows:

[0034] In this embodiment, during the use of an injection molding conveying pipe and centralized feeding system, injection molding granules enter the interior of the pipe body 1 through the inlet at the top of the pipe body 1 and fall onto the transmission belt 203. Guided by the baffles 3 on both sides of the transmission belt 203, the granules gradually slide down to the bottom of the inner side of the pipe body 1; while the injection molding granules in the middle area of ​​the transmission belt 203 can automatically fall off when they reach the edge of the pipe body 1.

[0035] Driven by the motor, the transmission rod 201 drives the transmission belt 203 to move, and the transmission plate 205 moves along the feeding direction, thereby realizing the continuous propulsion of materials and achieving the purpose of stable feeding.

[0036] During maintenance, operators can open the side plate 102 to visually inspect the internal structure of the tube body 1. When it is necessary to replace a certain transmission plate 205, the target transmission plate 205 can be rotated to the end position of the tube body 1 by rotating the transmission rod 201. At this time, the operator can manually pull out the old transmission plate 205 and insert the new transmission plate 205 without replacing the entire material propulsion mechanism 2, which improves maintenance efficiency and reduces replacement costs.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
