Description

Technical Field

[0001] This utility model relates to the field of plastic running track production technology, and in particular to a powder supply device for the production of plastic running track materials. Background Technology

[0002] During the production and installation of synthetic running tracks, various powdered and granular raw materials need to be mixed and stirred in precise proportions. The accuracy of the raw material ratio is a key factor determining the final physical properties of the running track, such as elasticity, wear resistance, and service life, and directly affects the quality of the project.

[0003] Currently, in many plastic running track material production sites, the addition of powdered raw materials still largely relies on manual operation. Workers typically weigh the powder manually, or in some cases, estimate it based on experience, and then directly add it to the mixing equipment. This traditional method has significant technical limitations: due to the arbitrariness and unavoidable errors of manual operation, it is difficult to guarantee the accuracy and consistency of the amount of material added each time, leading to deviations in the raw material ratio. This ratio error directly affects the final product, causing fluctuations in the performance of plastic running track materials from different production batches, making it difficult to effectively guarantee quality stability.

[0004] Furthermore, the powdered chemical raw materials used in the production of plastic running tracks typically have high requirements for storage environment due to their relatively sensitive chemical properties. During storage before feeding and transfer during production, the raw materials are exposed to the production workshop environment for extended periods. If the sealing performance of the storage or feeding device is inadequate, dust and impurities in the air will mix into the raw materials, causing contamination. More seriously, when the workshop environment has high humidity, the raw materials easily absorb moisture from the air, becoming damp and clumping. These contaminated or clumped raw materials have deteriorated physical and chemical properties; continued use will prevent them from being uniformly mixed with other materials in subsequent processes, ultimately severely impacting the purity and overall quality of the finished plastic running track from the source. However, existing feeding devices are often relatively simple in structure, generally lacking a sealing structure that can provide strong and reliable locking force, making it difficult to effectively isolate external environmental interference, and also failing to integrate solutions to the problem of accurate quantitative feeding.

[0005] Therefore, this utility model proposes a powder supply device for the production of plastic running track materials to overcome the shortcomings of the prior art. Utility Model Content

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a more detailed description of this utility model in conjunction with the accompanying drawings. This embodiment provides a powder supply device for the production of plastic running track materials, aiming to solve the problems of inaccurate manual feeding ratios and easy contamination in the prior art.

[0034] Please see Figures 1 to 4 This utility model discloses a powder supply device for the production of plastic running track materials, comprising a storage tank 1 as the main structure. The storage tank 1 is used to store powdered plastic running track raw materials, with an opening at the top and a conveying pipe 2 fixedly welded to the center of the bottom. To seal the storage tank 1, an annular sealing ring 4 is installed on the edge of the top opening, and a top cover 5 is placed on the sealing ring 4. To ensure that the top cover 5 and the storage tank 1 can be tightly pressed together, multiple sealing mechanisms 6 are symmetrically installed on the outer wall of the storage tank 1.

[0035] Please see Figure 1 and Figure 3The feeding mechanism 3 is installed at the bottom of the conveying pipe 2 to realize the quantitative and automatic feeding of powder. The feeding mechanism 3 mainly includes a fixed block 31 and an internal conveying component 37.

[0036] The fixing block 31 is a box-shaped structure, with its top end fixedly connected to the bottom end of the conveying pipe 2. A motor 32 is fixedly installed inside the cavity of the fixing block 31; in this embodiment, a reversible DC motor can be used. A disc-shaped grooved rod 34 is fixedly connected to the drive shaft end of the motor 32, and a radial groove is formed on the grooved rod 34. Two symmetrical support blocks 33 are rotatably connected to the outer periphery of the grooved rod 34 via bearings. Simultaneously, one end of a connecting rod 35 can slide freely within the groove of the grooved rod 34, while its other end is connected to the conveying assembly 37.

[0037] A guide plate 36 is also fixedly installed inside the fixing block 31. A horizontal groove is provided on the guide plate 36. See details. Figure 2 The cross-sectional structure is shown. The core component of the material conveying assembly 37 is a movable plate 371, the side of which slides into the groove of the guide plate 36, so that the movable plate 371 can only reciprocate in the horizontal direction. The end of the connecting rod 35 away from the groove rod 34 is fixedly connected to the front side of the movable plate 371.

[0038] A small storage bin 372 is fixedly connected to the bottom of the movable plate 371. A round cover 373 is rotatably connected to the bottom of the storage bin 372 via a pin. A second fixing block 374 is also fixedly connected to the bottom of the first fixing block 31. The inner bottom surface of the second fixing block 374 is a flat support surface, and a vertically downward discharge pipe 375 is opened on one side of it.

[0039] The workflow is as follows: In the initial state, the moving plate 371 moves the storage bin 372 directly below the conveying pipe 2. At this time, the round cover 373 of the storage bin 372 is stably supported by the inner bottom surface of the fixing block 374, keeping it closed, and the powder falls from the storage bin 1 into the storage bin 372. When material needs to be discharged, the motor 32 is started, and the motor 32 drives the grooved rod 34 to rotate. The rotation of the grooved rod 34 is converted into the linear motion of the moving plate 371 through the connecting rod 35 that slides in it. The moving plate 371 slides along the groove of the guide plate 36 towards the discharge pipe 375, driving the storage bin 372 to move synchronously. When the storage bin 372 is moved directly above the discharge pipe 375, its bottom cover 373, having lost the support of the inner bottom surface of the fixing block 374, flips downwards and opens under its own weight and the weight of the powder, allowing the measured amount of powder in the storage bin 372 to fall into the discharge pipe 375, completing one feeding cycle. Subsequently, the motor 32 reverses, driving all components to move in the opposite direction, causing the storage bin 372 to return to its original position below the conveying pipe 2. The cover 373 is then lifted and closed again, allowing for the next feeding cycle. This process is repeated continuously, achieving precise quantitative feeding.

[0040] Please see Figure 2 and Figure 4 The sealing mechanism 6 is used to quickly and reliably lock the top cover 5 onto the storage hopper 1. This mechanism includes a mounting block 61 fixedly connected to the outer wall of the storage hopper 1. A vertical slide rail is provided inside the mounting block 61. The lower end of a push rod 62 is man-operable, and its upper end is slidably connected inside the mounting block 61 and fixedly connected to a serrated rod 63. Multiple ratchet teeth are machined on one side of the serrated rod 63. Inside the mounting block 61, one end of a flexible steel spring 674 is also fixed, and the end of the spring 674 engages precisely between the ratchet teeth of the serrated rod 63, forming a one-way locking ratchet structure. On the side of the mounting block 61, a contact rod 675 is also slidably mounted, and its inner end can push the spring 674, separating it from the serrated rod 63.

[0041] A movable block 64 is fixedly connected to the top of the serrated rod 63. Two sliding pillars 65 are slidably connected to the movable block 64. A pressure rod 66 is fixedly connected to the outer side of each sliding pillar 65. At the same time, two upright support rods 671 are fixed to the top of the mounting block 61. A rotating shaft 672 is installed on each support rod 671, and the middle part of the pressure rod 66 is rotatably sleeved on the rotating shaft 672 to form a lever. In order to cooperate with the pressure rod 66, multiple protruding connecting blocks 673 are fixed to the outer edge of the top cover 5.

[0042] The working process is as follows: After placing the top cover 5 on the sealing ring 4, push the push rod 62 upward. The push rod 62 drives the serrated rod 63 and the moving block 64 to move upward synchronously. Due to the rise of the moving block 64, the lower end of the pressure rod 66 is pushed through the sliding column 65, causing the pressure rod 66 to rotate around the pivot 672. Its top end moves downward and finally presses tightly against the connecting block 673 of the top cover 5. As the push rod 62 continues to push upward, the clamping force increases, and at the same time, the serrated rod 63 is locked by the spring piece 674 to prevent it from sliding downward, thus achieving reliable locking and sealing. When it is necessary to open the top cover 5, simply push the contact rod 675 upward to push open the spring piece 674 and release the lock on the serrated rod 63. At this time, the push rod 62 can be easily pulled downward to release the pressure rod 66 and remove the top cover 5.

[0043] Working Principle: When using this device, quantitative feeding is performed through the feeding mechanism 3. The motor 32 is started, driving the grooved rod 34 connected to its drive end to rotate. The rotation of the grooved rod 34 drives the moving plate 371 to reciprocate linearly along the guide plate 36 via the connecting rod 35. As the moving plate 371 slides, the storage bin 372 at its bottom moves accordingly. In the initial position, the storage bin 372 is located directly below the conveying pipe 2, receiving the powdery raw material falling from the storage bin 1. At this time, its bottom cover 373 is supported and kept closed by the inner bottom surface of the fixing block 374. When the moving plate 371 moves to one side, causing the storage bin 372 to move above the discharge pipe 375, the cover 373 loses its support and opens due to gravity, allowing the powdery raw material in the storage bin 372 to fall out, completing one feeding cycle. Subsequently, motor 32 reverses or continues to rotate, causing storage bin 372 to return to its original position to receive powdered raw materials again, thereby realizing quantitative feeding of the device, accurately controlling the amount of powdered raw materials fed, eliminating the ratio error of manual feeding, and ensuring the stability of core performance such as elasticity and wear resistance of the track material.

[0044] When sealing the storage hopper 1 is required, place the top cover 5 on the sealing ring 4 at the top of the storage hopper 1. Push the push rod 62 of the sealing mechanism 6 upward. The push rod 62 drives the serrated rod 63 to move upward. The serrated rod 63 is locked by the spring piece 674 to prevent it from sliding down. The serrated rod 63 drives the moving block 64 to move upward, which in turn drives the pressure rod 66 to rotate around the pivot 672, so that the top of the pressure rod 66 presses tightly against the connecting block 673 of the top cover 5, thereby tightly connecting the top cover 5 and the storage hopper 1 and pressing the sealing ring 4 to achieve a reliable seal for the device. This structure can effectively block the direct flow of air between the inside of the device and the outside, prevent external dust, impurities and moisture from entering and contaminating the raw materials, and avoid raw material agglomeration or performance deterioration. When it is necessary to open the top cover 5, push the contact rod 675 upward to separate the spring piece 674 from the serrated rod 63 and release the lock. At this time, the push rod 62 can be pulled downward to drive a series of components to move in the opposite direction, so that the pressure rod 66 releases the pressure on the connecting block 673, and the top cover 5 can be removed.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
