Description

Technical Field

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

[0002] All-plastic running track material is made of pure PU (polyurethane) and has a granular surface structure, making it waterproof. Its surface layer possesses excellent physical elasticity and high wear resistance, effectively resisting various harsh weather conditions, prolonged sunlight, rainy seasons, and freezing weather. In the production of all-plastic running track material, high-quality polyurethane is generally selected as the base material. Then, appropriate fillers and high-purity additives are selected according to the actual application scenario to ensure a uniform and stable track surface. During the production process, various materials need to be mixed in appropriate proportions, usually manually, and then poured into a mixing tank for stirring.

[0003] However, in the production process of plastic running track materials, it is inconvenient to accurately proportion various materials and control the amount of each material added, thereby reducing the quality of the all-plastic running track production. Although some are equipped with weighing mechanisms, the raw materials after weighing are easily left in the weighing box, which further reduces the accuracy of the proportion of various materials. Therefore, we propose a control device for the production of plastic running track materials to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a control device for the production of plastic running track materials. It can accurately control the amount of various materials added, so that they are mixed in a certain proportion to ensure the mixing effect, thereby improving the quality of the production of all-plastic running tracks. In addition, through the cooperation of scraper and gate, the raw materials in the raw material box can be pushed out completely to avoid the presence of residues that would affect the accuracy of the material ratio, further improving the quality of the production of all-plastic running tracks.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a control device for the production of plastic running track materials, comprising a tank for mixing plastic running track materials, two weighing sensors fixedly connected to the top of the tank, a raw material box fixedly connected to the top of the weighing sensors, a feeding pipe fixedly connected to the bottom of the raw material box, two feeding pipes fixedly connected to the top of the tank, the feeding pipes being movably sleeved inside the feeding pipes, a PLC controller with a touch screen fixedly connected to the top of the tank, a feeding hopper fixedly connected to the top of the raw material box, a gate mechanism and a material ejection mechanism provided on the raw material box, the gate mechanism corresponding to the feeding pipes, a discharge pipe fixedly connected to the bottom of the tank, a discharge valve provided on the discharge pipe, a stirring and scraping discharge mechanism provided between the discharge pipe and the tank, and three support legs fixedly connected to the bottom of the tank.

[0006] A further feature of this invention is that the material ejection mechanism includes a servo motor fixedly connected to one side of the raw material box and a threaded sleeve rotatably connected to one side of the raw material box. A driving tooth is fixedly connected to the output shaft of the servo motor, and a driven tooth is fixedly sleeved on the outer side of the threaded sleeve. The driving tooth and the driven tooth mesh with each other. A lead screw is threaded inside the threaded sleeve, and a push plate is fixedly connected to one end of the lead screw. A wear-resistant rubber sleeve is fixedly sleeved on the outer side of the push plate, and the wear-resistant rubber sleeve is slidably sleeved inside the raw material box.

[0007] By adopting the above technical solution, when it is necessary to control the feeding ratio of raw materials for plastic running track materials, the raw materials can be poured into the raw material box through the feeding hopper. After tare, the weighing sensor weighs the raw materials. When the requirements are met, the feeding stops. In this way, multiple raw materials for plastic running track materials can be weighed for quantitative addition, so that they can be compared according to a certain ratio to ensure the quality of subsequent production of plastic running track materials. The servo motor is started by the PLC controller, which drives the rotation of the active gear. The active gear drives the rotation of the driven gear and the threaded sleeve. Under the guidance of the limit rod, the threaded sleeve drives the screw and the push plate to move inward.

[0008] A further feature of this invention is that a bearing is fixedly connected to one side of the raw material box, and the threaded sleeve is fixedly fitted inside the bearing.

[0009] By adopting the above technical solution, it is convenient to support the threaded sleeve, making its rotation more stable.

[0010] A further feature of this invention is that two limiting rods are slidably sleeved on one side of the raw material box, and both limiting rods are fixedly connected to one side of the push plate.

[0011] By adopting the above technical solution, the push plate can be guided and limited, making its movement more stable and smooth.

[0012] A further feature of this invention is that the gate mechanism includes an upper rack fixedly connected to the bottom of the lower limiting rod, a drive gear rotatably connected to the inner wall of the rear side of the raw material box, and a gate plate slidably sleeved in the feeding pipe. A lower rack is fixedly connected to the top of the gate plate, and both the upper rack and the lower rack mesh with the drive gear.

[0013] By adopting the above technical solution, the movement of the lower limit rod drives the upper rack to move inward, the upper rack drives the drive gear to rotate, and the drive gear drives the lower rack and the gate to move outward without blocking the feed pipe. The push plate continues to move inward to push the raw material to the feed pipe for feeding. Furthermore, through the contact between the wear-resistant rubber sleeve and the inner wall of the raw material box, the material adhering to the inner wall of the raw material box can be scraped off, ensuring that the raw material is completely discharged from the raw material box and avoiding the reduction of the accuracy of the proportioning due to the presence of raw material residue in the raw material box.

[0014] A further feature of this invention is that: an avoidance groove is provided on the bottom inner wall of the raw material box, the drive gear and the lower rack are located in the avoidance groove, a guide groove is provided on the bottom inner wall of the avoidance groove, and the gate is slidably sleeved in the guide groove.

[0015] By adopting the above technical solution, it is convenient to guide the lower rack and the gate, making their movement more stable.

[0016] The present invention is further configured as follows: the stirring scraping discharge mechanism includes a stirring motor fixedly connected to the top of the tank, a rotating shaft fixedly connected to the output shaft of the stirring motor, several stirring blades fixedly connected to both sides of the rotating shaft, a common scraper fixedly connected to one side of the several stirring blades on the same side, the two scrapers respectively movably abutting against the inner wall of the tank, and an auger fixedly sleeved on the outer side of the rotating shaft, the auger being located below the stirring blades and inside the discharge pipe.

[0017] By adopting the above technical solution, the stirring motor is started in reverse. The stirring motor drives the rotating shaft, stirring blades, scraper, and auger to rotate in reverse, which can efficiently stir and mix the raw materials evenly. The auger can tumble the raw materials at the bottom of the discharge pipe upwards, improving the efficiency of stirring and mixing. When the mixture needs to be discharged, the discharge valve is opened and the stirring motor is started normally. The stirring motor drives the rotation of the scraper and auger. The scraper can scrape the raw materials adhering to the inner wall of the tank into the discharge pipe. Through the normal rotation of the auger, the raw materials can be evenly and smoothly conveyed downwards, making the discharge smoother and more thorough, and avoiding the occurrence of blockages.
