Description

Technical Field

[0001] This utility model belongs to the field of plastic processing machinery technology, and specifically relates to a liquid dispensing device for masterbatch. Background Technology

[0002] In the field of plastics processing and masterbatch production, high-speed mixing tanks, as core equipment for material mixing, are widely used in the preparation of products such as color masterbatches and functional masterbatches. Their main function is to fully mix solid masterbatches with various additives through high-speed mixing to impart specific properties to the masterbatch (such as coloring, flame retardancy, and anti-aging). Among these, the addition of liquid additives has a significant impact on the final quality of the masterbatch, and the uniformity and accuracy of its addition directly determine the stability and consistency of the masterbatch's performance.

[0003] Currently, most small and medium-sized enterprises in the industry still use the traditional manual method to handle liquid additives: operators use simple tools such as measuring cups and funnels to pour the liquid material directly into the feed inlet or lid opening of the high-pressure mixing tank. This method has obvious technical limitations: on the one hand, manual pouring makes it difficult to control the flow rate and volume of the liquid, which can easily lead to local liquid accumulation, resulting in uneven mixing of the liquid and solid masterbatch, and potentially causing performance deviations in the final product (such as inconsistent color depth, unstable flame retardant effect, etc.); on the other hand, for scenarios requiring the compounding of multiple liquid additives in specific proportions, manual addition must be performed sequentially, which not only prolongs the mixing cycle but may also affect product quality due to errors in the operation sequence or dosage. In summary, the current method suffers from poor uniformity of liquid addition, insufficient accuracy in flow control, and weak equipment adaptability. Utility Model Content

[0004] In view of this, the present invention provides a liquid injection device for masterbatch, which can solve the problems of poor liquid injection uniformity, insufficient flow control accuracy, and weak equipment adaptability.

[0005] This utility model is implemented as follows: This utility model provides a liquid injection device for masterbatch, including a high-speed stirring pot and an internal stirring device. A cover is provided on the top of the high-speed stirring pot, and a discharge port is provided on one side of the bottom of the high-speed stirring pot. Multiple injection channels for injecting liquid into the high-speed stirring pot are provided on the top of the cover, and injection devices are provided inside the injection channels. The outer end of the injection device is connected to the output end of a corresponding metering pump through a connecting pipe. The input end of the metering pump is connected to a container holding the raw material through a connecting pipe.

[0006] The technical advantages of the liquid injection device for masterbatch provided by this utility model are as follows: By setting multiple injection channels in the lid of the high-speed stirring pan and cooperating with the injection device and metering pump, the problems of low efficiency and insufficient metering accuracy leading to uneven mixing in traditional masterbatch liquid injection are solved; the use of multiple injection channels can realize the simultaneous injection of various liquid additives and different injection methods, thereby improving production efficiency; the cooperation between the metering pump and the injection device ensures precise control of the liquid addition amount and reduces human operation errors; the coordinated work of each component allows the liquid to enter the high-speed stirring pan more evenly, helping the liquid and masterbatch to mix fully and improving the quality of masterbatch production.

[0007] Based on the above technical solution, the liquid injection device for masterbatch of this utility model can be further improved as follows: The filling device includes a telescopic injection tube, a forward and reverse motor, and a drive gear. A rack structure is provided on one side of the telescopic injection tube to cooperate with the movement of the gear.

[0008] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a forward and reverse motor as the driving source of the filling device; and by using a drive gear in conjunction with a rack and pinion structure to achieve the effect of torque transmission.

[0009] Furthermore, the output shaft of the forward and reverse motor is fixedly connected to the drive gear, one side of the telescopic injection tube meshes with the drive gear through a rack structure, and the other side is an arc shape that slides against the inner wall of the injection channel.

[0010] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by driving the active gear with a forward and reverse motor, and utilizing the meshing transmission between the active gear and the rack, the height displacement adjustment of the telescopic injection tube along the injection channel can be achieved.

[0011] Furthermore, the top of the telescopic injection tube is connected to the connecting tube via an adapter, and the bottom is equipped with different types of dispensing heads.

[0012] The beneficial effect of adopting the above-mentioned improvement scheme is that an adapter is set up to install a fixed connection pipe at the top of the telescopic injection tube.

[0013] Furthermore, the liquid outlet includes a spray type liquid outlet or a direct drip type liquid outlet.

[0014] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the spray-type liquid outlet head is suitable for low-viscosity liquids that require rapid dispersion, which can increase the contact area between the liquid and the masterbatch; the direct-flow drip-type liquid outlet head is suitable for high-viscosity liquids, avoiding liquid splashing. The setting of the two types of liquid outlet heads can meet the filling needs of liquids with different properties and improve the mixing uniformity.

[0015] Furthermore, the spray nozzle has a fan-shaped cross-section and outlet holes arranged in a ring at the bottom.

[0016] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the fan-shaped liquid outlet head can make the liquid form a large area and uniform spray range, avoid local liquid accumulation, ensure that the liquid and the masterbatch are quickly and fully mixed, and improve the mixing quality.

[0017] Furthermore, the internal flow channel of the DC dripping liquid outlet head is equipped with annular protrusions.

[0018] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the annular protrusion can create a throttling effect on high-viscosity liquids, avoid the deviation in the amount of liquid added due to excessive flow rate, and ensure the uniformity and accuracy of the addition of high-viscosity liquids.

[0019] Furthermore, a support base is fixedly connected to the bottom of the high-stirring pot.

[0020] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the overall stability of the high-speed stirring pot is enhanced by the support base, the vibration of the high-speed stirring pot during the stirring process is reduced, the accuracy and stability of liquid filling are avoided due to equipment shaking, and the reliability of the device operation is improved.

[0021] Furthermore, the inner wall of the filling channel is provided with a guide groove, and the outer wall of the telescopic injection pipe is provided with a sliding guide rail.

[0022] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a guide groove on the inner wall of the filling channel and sliding it in cooperation with the guide rail on the outer wall of the telescopic injection tube, the telescopic injection tube is provided with precise guidance for its extension and retraction, preventing the injection tube from deviating, ensuring the accuracy of the injection position, and further improving the filling accuracy.

[0023] Furthermore, the bottom of the lid can be detachably installed from the inner wall of the top edge of the high-stirring pot via a movable locking groove.

[0024] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by detachably installing the cover and the high-stirring pot through the movable locking groove, the cover installation is guaranteed to be firm and prevent liquid splashing during the filling process. It also facilitates the removal of the cover to clean and maintain the inside of the high-stirring pot and the filling device, thereby improving the convenience of operation and the cleanliness of the equipment. Compared with existing technologies, the beneficial effects of the liquid injection device for masterbatch provided by this utility model are as follows: First, automated injection is achieved through multiple injection channels in conjunction with the injection device, avoiding uneven distribution of liquid materials caused by manual operation. Second, the liquid flow rate is precisely controlled through the linkage between the metering pump and the injection device, ensuring the accuracy of the added amount and meeting the requirements of high-standard material mixing processes for liquid injection precision and uniformity. At the same time, the multi-channel design can realize the simultaneous injection of multiple liquids, improving production efficiency. Third, the length of the injection pipe extending into the high-stirring pot can be flexibly adjusted by using a telescopic injection pipe in conjunction with a forward and reverse motor and a drive gear and rack structure to adapt to the injection needs of different material heights or stirring states, allowing the liquid to be added at a more suitable position, further improving the mixing effect with the masterbatch. Fourth, the top of the telescopic injection pipe is connected to the connecting pipe by an adapter, which facilitates quick disassembly and assembly, improving maintenance convenience. Fifth, different types of liquid outlets are set at the bottom, which can be flexibly adapted according to the liquid characteristics (such as viscosity and injection requirements), enhancing the applicability of the device to different materials.

[0028] like Figure 1-3The image shows an embodiment of a liquid filling device 14 for masterbatch provided by this utility model. In this embodiment, it includes a high-speed stirring pot 10 and an internal stirring device. A cover 11 is provided on the top of the high-speed stirring pot, and a discharge port 12 is provided on one side of the bottom of the high-speed stirring pot. Multiple sets of filling channels 13 for injecting liquid into the high-speed stirring pot are provided on the top of the cover, and filling devices are provided inside the filling channels. The outer end of the filling device is connected to the output end of the corresponding metering pump 15 through a connecting pipe. The input end of the metering pump is connected to the container holding the raw material through a connecting pipe.

[0029] The internal stirring device includes a drive motor and a stirring rod, with stirring blades installed on the stirring rod.

[0030] In the above technical solution, the filling device includes a telescopic injection tube 141, a forward and reverse motor 142, and a drive gear 143. A rack structure 1411 for cooperating with the gear is provided on one side of the telescopic injection tube.

[0031] The cover has a compartment located near the middle of the filling channel. The fixed end of the forward and reverse motor is fixedly installed in the compartment via a base. The drive gear extends to the outside of the compartment and meshes with the rack.

[0032] Furthermore, in the above technical solution, the output shaft of the forward and reverse motor is fixedly connected to the drive gear, one side of the telescopic injection tube meshes with the drive gear through a rack structure, and the other side is arc-shaped and slides against the inner wall of the injection channel.

[0033] Furthermore, in the above technical solution, the top end of the telescopic injection tube is connected to the connecting tube via an adapter 16, and the bottom end is provided with different types of liquid outlet heads 17.

[0034] The adapter has a rubber pad at the bottom that fits the shape of the top of the telescopic injection tube, and a cylindrical interface at the top that fits the connecting tube.

[0035] Furthermore, in the above technical solution, the liquid outlet head includes a spray type liquid outlet head 171 or a direct drip type liquid outlet head 172.

[0036] Furthermore, in the above technical solution, the cross-sectional shape of the spray-type liquid outlet head is fan-shaped, and the bottom is provided with liquid outlet holes arranged in a ring.

[0037] Furthermore, in the above technical solution, the internal flow channel of the DC dripping liquid outlet head is provided with an annular protrusion 1721.

[0041] Specifically, the principle of this utility model is as follows: the container holding the raw materials delivers the liquid to the metering pump through the connecting pipe. The metering pump precisely controls the liquid flow rate to ensure that the amount added meets the process requirements. After metering, the liquid enters the corresponding filling channel on the cover through the connecting pipe and is finally delivered by the filling device.

[0042] Before use, the reversible motor drives the active gear, which meshes with the rack of the telescopic injection pipe to adjust the downward displacement of the injection pipe, extending it to 50cm inside the stirring pan. Combined with the guide groove and guide rail's limiting mechanism, this allows for precise control of the injection depth to adapt to different material states. The outlet head at the bottom of the telescopic injection pipe can be selected as needed. The spray type achieves large-area dispersion through a fan-shaped cross-section and annular outlet holes, while the direct-flow drip type uses internal annular protrusions to stabilize the flow rate of high-viscosity liquids, ensuring uniform contact between the liquid and the masterbatch. Meanwhile, the removable cover facilitates maintenance, and the support base ensures stable equipment operation, achieving automation, precision, and adaptability in liquid addition.
