Description

Technical Field

[0001] This utility model belongs to the field of antistatic masterbatch production technology, specifically relating to a raw material mixing device for antistatic masterbatch production. Background Technology

[0002] In the production process of antistatic masterbatch, raw material mixing is a crucial step, as its mixing effect directly affects the quality and performance of the final product.

[0003] Antistatic masterbatch raw materials often contain multiple components such as resin particles and antistatic agent powder. Some raw materials may absorb moisture slightly due to changes in the humidity of the storage environment, which will increase the adhesion between particles and easily form small agglomerates. In addition, if there are lumpy clumps in the raw materials (such as resin clumping due to moisture or antistatic agent agglomeration), these irregular lumps are very likely to get stuck in the narrow channels of the device (such as the feed port or the dead corner of the mixing) during the falling or mixing process, becoming the "initial blockage point". The continuous accumulation of raw materials will further expand the blockage range. Therefore, those skilled in the art have provided a raw material mixing device for the production of antistatic masterbatch to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed raw material mixing device for the production of antistatic masterbatch in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A raw material mixing device for producing antistatic masterbatch includes a mixing tank. A pretreatment crushing and feeding component is fixedly installed on the top of the mixing tank. A stirring and transmission component is provided on the mixing tank. An anti-clogging stirring component that cooperates with the stirring and transmission component is rotatably connected to the inner side wall of the mixing tank. The anti-clogging stirring component includes a first stirring rod rotatably connected inside the mixing tank. A unblocking component is provided at the bottom of the first stirring rod.

[0007] As a further optimization of this utility model, the unblocking component includes a connecting plate fixedly connected to the bottom of the first stirring rod, a second stirring rod fixedly installed on one side of the bottom of the connecting plate, and an unblocking rod fixedly connected to the middle of the bottom of the connecting plate.

[0008] As a further optimization of this utility model, the mixing tank has a conical structure, the bottom of the mixing tank is connected to a discharge port, a discharge valve is installed on the discharge port, and the discharge end of the discharge port is connected to a collection box.

[0009] As a further optimization of this utility model, the stirring transmission assembly includes a second servo motor fixedly installed on the side wall of the mixing tank, the top end of the first stirring rod rotating through the top of the mixing tank, and a synchronous pulley fixedly sleeved on both the output end of the second servo motor and the top of the first stirring rod, and a synchronous belt fixedly sleeved between the two connecting discs.

[0010] As a further optimization of this utility model, the pretreatment crushing and feeding assembly includes a feeding box fixedly installed on the top of the mixing tank. The inner side wall of the feeding box is rotatably connected to two symmetrically distributed crushing rollers. The discharge end of the feeding box and the inlet end of the mixing tank are connected by a discharge pipe.

[0011] As a further optimization of this utility model, one end of each of the two crushing rollers rotates through the side wall of the feeding box, and one end of each of the two crushing rollers is fixedly fitted with a first transmission gear. The two first transmission gears mesh with each other. A second servo motor is fixedly installed on the side wall of the feeding box and is fixedly connected to one end of the crushing roller. Protective covers are fitted on the outer sides of the two first transmission gears and the outer sides of the second servo motor.

[0012] As a further optimization of this utility model, a controller is fixedly installed on the mixing tank, and the controller is electrically connected to the first servo motor and the second servo motor respectively.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model, the anti-clogging mixing component, while the mixing transmission component drives the first mixing rod to mix, causes the unblocking rod to rotate synchronously, continuously unblocking the antistatic masterbatch at the bottom of the mixing tank and the discharge port, completely solving the clogging problem of traditional devices. It can ensure the continuous and stable operation of the device without manual intervention, and significantly improves production efficiency.

[0015] 2. This utility model, by setting up a pre-treatment crushing and feeding component, uses a first servo motor to drive the meshing first transmission gear, which drives two crushing rollers to rotate synchronously in opposite directions. This can efficiently crush the antistatic masterbatch fed into the feeding box, making the antistatic masterbatch particles uniform before entering the mixing tank through the feeding pipe. This avoids the problem of uneven mixing caused by the difference in antistatic masterbatch particles from the source, and greatly improves the final mixing quality of the antistatic masterbatch.

[0016] 3. In this utility model, the controller is electrically connected to the first servo motor and the second servo motor respectively. The operator can set and control the crushing and mixing operation parameters through the controller, realizing the automated and coordinated operation of the pretreatment and mixing stages. At the same time, the controller can also control the opening and closing of the feeding valve, which simplifies the operation process, reduces the difficulty of operation, and even non-professionals can quickly get started, reducing the interference of human operation on the production process.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] like Figure 1 , Figure 2 As shown, a raw material mixing device for the production of antistatic masterbatch includes a conical mixing tank 1 with a discharge port 6 at its bottom for discharging the mixed antistatic masterbatch. To precisely control the discharge process, a discharge valve 5 is installed on the discharge port 6. The discharge valve 5 is a solenoid valve that can control the discharge flow rate according to production needs. The discharge end of the discharge port 6 is connected to a collection box 7 for collecting finished products. Meanwhile, a controller 4 is fixedly installed on the outside of the mixing tank 1 to coordinate the operation of the entire device, ensuring the automated operation of the device.

[0025] like Figure 1 , Figure 2As shown, before the antistatic masterbatch enters the mixing tank 1, it needs to be pre-treated by the pre-treatment crushing and feeding assembly 2. The feeding box 201 in the pre-treatment crushing and feeding assembly 2 is fixed to the top of the mixing tank 1 as the initial feeding area of ​​the antistatic masterbatch. Two symmetrically distributed crushing rollers 204 are rotatably connected to its inner side wall for crushing the antistatic masterbatch in block or large particle form. When crushing is required, the first servo motor 203 installed on the side wall of the feeding box 201 is started. The first servo motor 203 drives the first transmission gear 202 fixedly connected to it to rotate. Since the two first transmission gears 202 mesh with each other and are respectively fixedly sleeved on one end of the two crushing rollers 204 that penetrate the side wall of the feeding box 201, the two crushing rollers 204 will rotate synchronously in opposite directions to achieve efficient crushing of the antistatic masterbatch. The crushed antistatic masterbatch then enters the mixing tank 1 through the discharge pipe 205 that connects the feeding box 201 and the mixing tank 1.

[0026] like Figure 3 , Figure 4 As shown, after the antistatic masterbatch enters the mixing tank 1, the anti-clogging mixing component 9 is driven by the stirring transmission component 3 to complete the mixing and anti-clogging operations. The second servo motor 301 in the stirring transmission component 3 is fixed to the side wall of the mixing tank 1. The output end of the second servo motor 301 and the top end of the first stirring rod 901 in the anti-clogging mixing component 9 are both fixedly fitted with synchronous wheels 302. The two synchronous wheels 302 are connected by a synchronous belt 303. When the second servo motor 301 starts, it can drive the first stirring rod 901 to rotate inside the mixing tank 1 to achieve the mixing of the antistatic masterbatch. At the same time, the connecting plate 902 fixedly connected to the bottom of the first stirring rod 901 rotates synchronously with it. The second stirring rod 904 on one side of the bottom of the connecting plate 902 further enhances the mixing effect. When the second stirring rod 904 rotates, the unblocking rod 903 rotates under the action of the connecting plate 902, effectively preventing the antistatic masterbatch from clogging the bottom of the mixing tank 1 and the discharge port 6.

[0027] like Figure 1 , Figure 2 As shown, to ensure the safety and stability of the device operation, protective covers 8 are provided on the outer sides of the two first transmission gears 202 and the outer side of the second servo motor 301 to prevent external impurities from interfering with the transmission process and to prevent operators from accidentally touching moving parts and causing safety hazards. In addition, the controller 4 is electrically connected to the first servo motor 203 and the second servo motor 301 respectively. The operator can precisely adjust the speed of the two motors through the controller 4, thereby controlling the crushing efficiency and stirring speed to meet the mixing requirements of different antistatic masterbatches. The entire device has a high degree of automation, good mixing effect, and effectively solves the problem of easy clogging in traditional mixing devices.

[0028] It should be noted that, in the operation of this raw material mixing device for the production of antistatic masterbatch, the operator sets the parameters through the controller 4, and then puts the antistatic masterbatch to be mixed into the feeding box 201 of the pretreatment crushing and feeding component 2. After starting the device, the controller 4 first sends a running signal to the first servo motor 203.

[0029] After the first servo motor 203 starts, it drives the first transmission gear 202 fixedly connected to it to rotate. Since the two first transmission gears 202 mesh with each other and are respectively sleeved on the ends of the two crushing rollers 204, the two crushing rollers 204 rotate synchronously in opposite directions, crushing the antistatic masterbatch with large blocks or particles in the feeding box 201, so as to make the antistatic masterbatch particles uniform and avoid large pieces of antistatic masterbatch from affecting the subsequent mixing effect. The crushed antistatic masterbatch falls naturally into the conical mixing tank 1 through the feeding pipe 205, completing the antistatic masterbatch pretreatment stage.

[0030] After the antistatic masterbatch enters the mixing tank 1, the controller 4 synchronously starts the second servo motor 301 of the stirring transmission assembly 3. The synchronous wheel 302 at the output end of the second servo motor 301 drives the synchronous wheel 302 at the top of the first stirring rod 901 in the anti-clogging stirring assembly 9 to rotate through the synchronous belt 303. This causes the first stirring rod 901 to rotate at high speed in the mixing tank 1, performing preliminary stirring and mixing of the antistatic masterbatch. At the same time, the connecting plate 902 at the bottom of the first stirring rod 901 rotates with it, and the second stirring rod 904 on one side of the connecting plate 902 further enhances the stirring intensity, ensuring that the antistatic masterbatch is mixed evenly.

[0031] During the mixing process, the second stirring rod 904 rotates, causing the unblocking rod 903 in the middle of the connecting plate 902 to rotate continuously, effectively preventing the antistatic masterbatch from accumulating and clogging at the bottom of the mixing tank 1 and the discharge port 6. After the antistatic masterbatch is mixed, the operator controls the drive mechanism of the discharge valve 5 through the controller 4 to open the valve in the discharge port 6. The mixed antistatic masterbatch enters the collection box 7 through the discharge port 6 for collection. The entire process is closed-loop. During this period, the protective cover 8 protects the first transmission gear 202 and the second servo motor 301, ensuring the stable operation of the device.

[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
