Description

Technical Field

[0001] This utility model belongs to the field of dye production technology, and in particular relates to a raw material mixing and proportioning device for dye production and processing. Background Technology

[0002] In the field of dye production and processing, accurate raw material mixing ratio is a key link to ensure the hue, fastness and performance stability of the final product. Current mixing ratio devices usually consist of three parts: storage unit, quantitative unit and mixing unit. The core of these devices is to achieve accurate metering and delivery of various solid powder or liquid raw materials.

[0003] Currently, the most widely used metering units in the industry, especially for powdery and granular raw materials, often employ a gravity metering structure consisting of a conical metering cylinder, a feed pipe connected to its bottom, and a valve to control the discharge. The working principle is as follows: after the raw material is weighed and metered inside the conical cylinder, the operator or control system opens the valve, and the material falls into the mixing unit below through the feed pipe under its own gravity.

[0004] While the conical cylinder used in existing mixing and proportioning devices facilitates the convergence of materials towards the outlet, its static wall surface easily causes materials, especially fine powders, to adhere and stick to the wall. After each metering, some raw materials remain on the cylinder wall and in the corners, which cannot be completely discharged by gravity. Furthermore, during the gravity feeding process, powder materials are prone to bridging or clogging when passing from the wide conical cylinder through the relatively narrow feed pipe, resulting in reduced mixing and proportioning accuracy.

[0005] To address this issue, we provide a raw material mixing and proportioning device for dye production and processing. Utility Model Content

[0006] The purpose of this utility model is to provide a raw material mixing and proportioning device for dye production and processing. Through the structural cooperation of the discharge mechanism and the scraping mechanism, it solves the problem that the mixing and proportioning accuracy of existing mixing and proportioning devices is easily reduced due to the inability of materials to be effectively discharged during use.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a raw material mixing and proportioning device for dye production and processing, comprising a proportioning metering cylinder, a connecting pipe at the top of the proportioning metering cylinder, a guide cylinder on the outer circumferential surface of the bottom end of the proportioning metering cylinder, and a weighing mechanism mounted on the upper surface of the guide cylinder; a discharge mechanism is provided on one side of the connecting pipe, the discharge mechanism comprising a cylinder fixedly connected to the top of the proportioning metering cylinder, a connecting plate fixedly connected to the output end of the cylinder, a fixed rod fixedly connected to the bottom of the connecting plate and extending into the proportioning metering cylinder, a sealing plate fixedly connected to the bottom of the fixed rod and located inside the proportioning metering cylinder, and a top plate disposed on the top of the sealing plate; a scraping mechanism is provided at the bottom of the connecting plate, the scraping mechanism comprising a movable tube rotatably connected to the outer circumferential surface of the fixed rod, a hexagonal rotating rod fixedly connected to the bottom of the movable tube, scrapers fixedly connected to the top and bottom of one side of the hexagonal rotating rod respectively, and a drive assembly disposed on one side of the cylinder.

[0010] The present invention is further configured such that the driving component includes a motor fixedly connected to the bottom of the connecting plate, a first gear fixedly connected to the output end of the motor, and a second gear meshing with one side of the first gear.

[0011] The present invention is further configured such that the output end of the hydraulic cylinder abuts against the fixed plate, and the bottom of the hydraulic cylinder is fixedly connected to the mounting ring.

[0012] The present invention is further configured such that the top of the weighing sensor is in contact with the fixed plate, and the size of the slide groove is adapted to the slider.

[0013] The present invention is further configured such that the sealing plate is in close contact with the inner side of the bottom of the proportioning metering cylinder, thereby sealing the bottom of the proportioning metering cylinder through the sealing plate.

[0027] Example 1

[0028] Please see Figures 1-5 This utility model is a raw material mixing and proportioning device for dye production and processing, including a proportioning metering cylinder 1, a connecting pipe 2 at the top of the proportioning metering cylinder 1, a guide cylinder 3 on the outer circumferential surface of the bottom end of the proportioning metering cylinder 1, and a weighing mechanism 4 installed on the upper surface of the guide cylinder 3; a discharge mechanism 5 is provided on one side of the connecting pipe 2, the discharge mechanism 5 includes a cylinder 51 fixedly connected to the top of the proportioning metering cylinder 1, a connecting plate 52 fixedly connected to the output end of the cylinder 51, and a part fixedly connected to the bottom of the connecting plate 52 and extending into the proportioning cylinder 1. The metering cylinder 1 has a fixed rod 53, a sealing plate 54 fixedly connected to the bottom of the fixed rod 53, and a top plate 55 located on the top of the sealing plate 54 and inside the metering cylinder 1. The bottom of the connecting plate 52 is provided with a scraping mechanism 6, which includes a movable tube 61 rotatably connected to the outer peripheral surface of the fixed rod 53, a hexagonal rotating rod 62 fixedly connected to the bottom of the movable tube 61, scrapers 63 fixedly connected to the top and bottom of one side of the hexagonal rotating rod 62, and a drive assembly 64 located on one side of the cylinder 51.

[0029] As a preferred embodiment of the above: a flange is fixedly connected to the top surface of the connecting pipe 2 for connection with the pipeline of the storage unit. During connection, the existing mature material conveying components on the storage unit extend into the connecting pipe 2 to ensure that the material inside the storage unit can smoothly and completely enter the proportioning and metering cylinder 1. The guide cylinder 3 is in close contact with the proportioning and metering cylinder 1. The bottom of the fixed rod 53 extends through to the proportioning and metering cylinder 1 and connects with the sealing plate 54. The movable pipe 61 is rotatably connected to the fixed rod 53 through a bearing. The bottom of the movable pipe 61 extends to the bottom of the top plate 55 and connects with the sealing plate 54. A hexagonal rotating rod 62 is connected to the bottom surface of a fixed rod 53 via bearings. A top plate 55 is located on the bottom surface of a movable tube 61. Both the top plate 55 and the proportioning cylinder 1 are rotatably connected to the movable tube 61 via bearings. Scrapers 63 connected to the top and bottom of one side of the hexagonal rotating rod 62 are in close contact with the bottom of the top plate 55 and the top of the sealing plate 54, respectively. The proportioning cylinder 1 is used to hold the dye raw materials to be proportioned for weighing and metering. Its straight cylinder structure facilitates material flow and drainage, avoiding the drawbacks of traditional conical cylinders. To address the issue of material buildup in the mixing cylinder, connecting pipe 2 connects the storage unit to the mixing cylinder 1, ensuring smooth entry of raw materials. Guide cylinder 3 fits tightly with the mixing cylinder 1, ensuring sealing and structural stability. Cylinder 51 provides power, driving the connecting plate 52 and the entire structure below to move up and down, controlling the opening and closing of the discharge port at the bottom of the mixing cylinder 1. Connecting plate 52 connects cylinder 51 to fixing rod 53, transmitting power. Fixing rod 53 connects to sealing plate 54, located at the bottom of the mixing cylinder 1, which is controlled by its up-and-down movement. The opening and closing of the discharge port, with its top conical surface design, facilitates material guidance and discharge. The top plate 55 fixing rod 53 moves up and down to scrape off the material adhering to the cylinder wall and prevent it from sticking to the wall. The movable tube 61 can rotate under the drive component 64, transmitting power to the hexagonal rotating rod 62. The hexagonal rotating rod 62 drives the scraper 63 to rotate, scraping the top plate 55 and sealing plate 54. It also uses its own polygonal structure to shake off the adhering material when rotating. The scraper 63 is used to scrape off the material adhering to the top plate 55 and sealing plate 54 to ensure complete discharge.

[0030] Example 2

[0031] Please see Figures 1-5Based on Embodiment 1, the weighing mechanism 4 includes a mounting ring 41 fixedly connected to the surface of the guide cylinder 3, a mounting hole 42 opened at the top of the mounting ring 41, a support frame 43 fixedly connected to the top of the mounting ring 41, a weighing sensor 44 fixedly connected to the top of the support frame 43 by bolts, a fixing plate 45 located at the top of the weighing sensor 44 and fixedly connected to the proportioning metering cylinder 1, a hydraulic cylinder 46 set on the mounting ring 41 on one side of the support frame 43, a slider 47 fixedly connected to one side of the proportioning metering cylinder 1, a sliding groove 48 opened inside one side of the guide cylinder 3, and a limiting cylinder 49 sleeved on the surface of the connecting pipe 2. The bottom of the limiting cylinder 49 extends into the interior of the proportioning metering cylinder 1 and communicates with the top plate 55. The drive assembly 64 includes a motor 641 fixedly connected to the bottom of the connecting plate 52, a first gear 642 fixedly connected to the output end of the motor 641, a second gear 643 meshing with one side of the first gear 642, the output end of the hydraulic cylinder 46 abutting against the fixed plate 45, the bottom of the hydraulic cylinder 46 fixedly connected to the mounting ring 41, the top of the weighing sensor 44 contacting the fixed plate 45, the size of the slide groove 48 being adapted to the slider 47, the sealing plate 54 being in close contact with the inner side of the bottom of the proportioning cylinder 1, sealing the bottom of the proportioning cylinder 1 through the sealing plate 54, the top plate 55 contacting the inner top of the proportioning cylinder 1, and the top of the sealing plate 54 having a conical surface design.

[0032] As a preferred embodiment of the above, the fixed plate 45 is fixedly connected to the proportioning cylinder 1, and the bottom of the limiting cylinder 49 extends into the interior of the proportioning cylinder 1 and communicates with the top plate 55. The limiting cylinder 49 and the proportioning cylinder 1 are in close contact, ensuring the sealing of its extended position. The diameter of the discharge end of the connecting pipe 2 is the same as the inner diameter of the limiting cylinder 49, and the diameter of its conveying part is smaller than the inner diameter of the limiting cylinder 49. The limiting cylinder 49 can move along the surface of the connecting pipe 2, and the second gear 643 is fixedly connected to the surface of the movable pipe 61. The entire device can be connected to existing mature mixing equipment through the mounting ring 41 and the mounting hole 42. When connecting, a sealing ring can be added to the bottom surface of the guide cylinder 3 to ensure the sealing at the connection with the mixing equipment, and after connection, the bottom end of the guide cylinder 3 communicates with the mixing equipment. Mounting ring 41 serves as the mounting base for the entire device. Support frame 43 supports weighing sensor 44, which monitors the weight of material in the mixing cylinder 1 in real time to ensure mixing accuracy. Fixing plate 45 transfers weight to weighing sensor 44, and hydraulic cylinder 46 locks or releases the mixing cylinder 1, facilitating weighing or discharging operations. When hydraulic cylinder 46 is in contact with fixing plate 45, weighing sensor 44 is not performing weighing operations. Slider 47 works in conjunction with slide 48 to guide the mixing cylinder 1 to move smoothly in the vertical direction. Drive assembly 64 rotates movable tube 61, driving scraper 63 to perform cleaning operations.

[0033] The working principle of this utility model is as follows: First, it is fixedly connected to the mixing equipment through the mounting ring 41. The connecting pipe 2 is connected to the raw material storage unit through the flange. The number of devices to be installed between the mixing equipment and the storage equipment can be selected according to the type of material and the requirements. The hydraulic cylinder 46 retracts and no longer abuts against the fixed plate 45. The weight of the proportioning metering cylinder 1 and all its structures acts on the weighing sensor 44, and the system enters the weighing state. The raw material enters the proportioning metering cylinder 1 from the storage unit through the connecting pipe 2. The weighing sensor 44 monitors the weight of the material in real time. When the preset weight is reached, the hydraulic cylinder 46 extends and abuts against the fixed plate 45 to lock the proportioning metering cylinder 1 and prevent it from shaking in subsequent operations.

[0034] During the discharge stage, cylinder 51 is activated, pushing the connecting plate 52, fixing rod 53, and sealing plate 54 downwards as a whole. The sealing plate 54 disengages from the bottom opening of the proportioning cylinder 1, forming a discharge channel. Under the action of gravity, the material is discharged downwards along the conical surface of the sealing plate 54. At the same time, the top plate 55 scrapes off the material adhering to the cylinder wall as the fixing rod 53 moves downwards, preventing residue from sticking to the wall. After the discharge is completed, the motor 641 in the drive assembly 64 is activated, driving the first gear 642, the second gear 643, and the movable tube 61 to rotate, thereby causing the hexagonal rotating rod 6 to rotate. 2. The scraper 63 rotates and scrapes the lower surface of the top plate 55 and the upper surface of the sealing plate 54 to further clean up the adhering fine particles. The non-circular cross section of the hexagonal rotating rod 62 generates centrifugal force when rotating, which helps to shake off the material adhering to the scraper 63 and the rotating rod, ensuring thorough discharge. The entire process realizes full-process automated control from weighing, locking, discharge to cleaning, effectively solving the problems of material residue and poor discharge in traditional proportioning devices, and significantly improving the accuracy and reliability of raw material proportioning in the dye production process.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
