Description

Technical Field

[0001] This utility model relates to the field of plastic color matching machines, and in particular to an easy-to-assemble color powder output device and a plastic color matching machine. Background Technology

[0002] In the plastics processing industry, plastic color matching is a crucial step, directly affecting the color quality and consistency of the final plastic products. As a key piece of equipment for achieving plastic color matching, the performance and reliability of the color powder output device of the plastic color matching machine plays a decisive role in the entire color matching process.

[0003] Most existing plastic color mixing machines use a fixed structure for their toner output devices. While this structure can meet basic toner output requirements to some extent, it reveals several problems in actual use. Firstly, due to the adhesiveness and fluidity of toner, residual toner easily accumulates in the feeding channel and key components such as the feeding screw during long-term use. This residual toner affects the accuracy and stability of the toner output, leading to deviations in the amount of toner output each time, thus impacting the color quality of plastic products. Secondly, the fixed structure of existing devices makes cleaning the feeding channel and feeding screw extremely difficult, often requiring the disassembly of numerous parts, consuming significant time and manpower, and potentially causing equipment damage, increasing maintenance costs and production downtime.

[0004] On the other hand, existing toner output devices also have shortcomings in controlling and measuring the powder delivery rate. Accurate control of the powder delivery rate is one of the key factors in ensuring the quality of plastic color matching, but most existing devices lack effective powder delivery rate measurement and feedback mechanisms, making it impossible to accurately monitor the powder delivery rate in real time and thus difficult to achieve precise color matching control. This not only leads to fluctuations in the color of plastic products and increases the defect rate, but also increases the waste of raw materials and raises production costs.

[0005] In summary, existing plastic color mixing machine powder output devices have many problems that urgently need to be solved in terms of ease of cleaning, equipment maintenance, and powder delivery control. Therefore, developing a detachable powder output device to solve these problems and improve the performance and reliability of plastic color mixing machines is of significant practical importance.

[0014] Furthermore, a positioning space is formed within the powder feeding base to position the powder feeding mechanism in the circumferential direction, and the front positioning surface and the positioning space together constrain the powder feeding mechanism to a set position.

[0015] Furthermore, the powder feeding base has a rear positioning member that positions the powder feeding mechanism in the retraction direction of the powder feeding screw, and the rear positioning member is detachably attached to the powder feeding base.

[0016] Furthermore, the powder feeding base has a limiting plate that restricts the downward movement of the transmission assembly.

[0017] Furthermore, the powder feeding mechanism also includes a detection module, which includes:

[0018] A trigger element that is connected in transmission to the transmission assembly;

[0019] The detection element, wherein the trigger element triggers the detection element at a set position to generate a position signal; and

[0020] The control unit determines the powder feeding amount by judging the number of rotations of the powder feeding screw based on the position signal.

[0021] Furthermore, the detection element is a non-contact proximity switch, which is one of a Hall element, an inductive sensor, a capacitive sensor, and a reed switch.

[0022] Furthermore, the powder feeding base has a motor, and the motor and the transmission assembly are detachably coupled together.

[0023] Secondly, the plastic color matching machine provided by this utility model includes a machine body and a color powder output device, wherein the color powder output device is the color powder output device for easy assembly of the plastic color matching machine described above.

[0041] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0042] Example 1:

[0043] Please see Figures 1 to 6 In this embodiment, the color powder output device 200 is installed on the plastic color mixing machine 100 and is used to transport color powder to the mixing chamber 101 of the plastic color mixing machine. The color powder output device 200 includes a powder feeding base 210 and a color powder cylinder 220. The powder feeding base 210 is fixedly connected to the body of the plastic color mixing machine.

[0044] In this embodiment, a powder feeding base 210 is equipped with a powder feeding channel 260 and a powder feeding mechanism 280. The powder feeding channel 260 has powder inlets and powder outlets spaced apart along its length. The powder outlet is connected to the mixing chamber 101 of the plastic color mixing machine. The powder feeding mechanism 280 includes a transmission component 282 and a powder feeding screw 283 that are connected by a transmission mechanism. The powder feeding screw 283 is detachably inserted into the powder feeding channel 260 to transfer the color powder from the powder inlet to the powder outlet.

[0045] At least one of the powder feeding mechanism 280 and the powder feeding channel 260 is detachably attached to the powder feeding base 210. This can be either the powder feeding mechanism 280 or the powder feeding channel 260, or both. This design allows for easy and thorough cleaning of the powder feeding screw 283 and the powder feeding channel 260 by simply detaching either the powder feeding mechanism 280 or the powder feeding channel 260 from the powder feeding base 210. This eliminates the need for disassembling numerous parts, reducing cleaning time and labor costs, lowering the risk of equipment damage due to improper cleaning, effectively reducing maintenance costs, minimizing production downtime caused by equipment maintenance, and improving production efficiency. During the cleaning process, compressed air, a soft brush, or other cleaning tools can be used to remove residual color powder from the powder feeding channel 260 and the powder feeding screw 283. After cleaning, the powder feeding mechanism 280 can be reinstalled onto the powder feeding base 210 to restore the normal operation of the equipment.

[0046] In this embodiment, the transmission assembly 282 can be a gearbox or a reduction gearbox, which includes a transmission base 281 and a transmission component (gear transmission component or worm gear transmission component, etc.) built into the transmission base 281. The powder feeding screw 283 is connected to the output end of the transmission assembly 282 and is used to move the color powder in the powder feeding channel 260 from the powder inlet to the powder outlet. Further, the powder feeding base 210 has a motor 240, and the motor 240 and the transmission assembly 282 are detachably coupled. That is, the input end of the transmission assembly 282 is connected to the powder feeding drive motor 240 through a detachable coupling mechanism 290, which facilitates the disassembly of the powder feeding mechanism 280 and further improves the convenience of maintenance and cleaning.

[0047] In this embodiment, the powder feeding base 210 includes a fixed base 2101 and a powder cylinder base 2102. The fixed base 2101 is fixed to the body of the plastic color mixing machine, and the color powder cylinder 220 is detachably attached to the powder cylinder base 2102. The motor 240 is mounted on the fixed base 2101. The color powder cylinder 220 is detachably positioned above the powder cylinder base 2102, so that the color powder cylinder 220 has an installed state installed on the powder cylinder base 2102 and a detached state removed from the powder cylinder base 2102. In the installed state, the color powder cylinder 220 is connected to the powder cylinder base 2102 through a specific connection structure. At the same time, a discharge port 2212 is opened at the bottom of the color powder cylinder 220 for conveying color powder from the color powder cylinder 220 to the powder inlet of the powder feeding channel 260. The detachable design of the color powder cartridge 220 also makes it easy to change the color powder. The type of color powder can be quickly changed without disassembling the entire device, which can meet the needs of multi-variety, small-batch plastic product production.

[0048] In this embodiment, the bottom of the powder cartridge holder 2102 is designed with an installation interface that matches the fixed seat 2101, such as a snap-fit ​​or slot structure, to achieve a stable connection between the two. When the powder cartridge holder 2102 is installed in place, its bottom fits tightly against the fixed seat 2101, thereby limiting the top of the transmission seat 281 located between the two, ensuring that the transmission seat 281 will not move in the vertical direction, and guaranteeing the stability of the powder feeding mechanism 280.

[0049] In some embodiments, such as Figure 3 As shown, the powder outlet 261 of the powder feeding channel 260 faces downwards, and this powder outlet 261 is connected to the mixing chamber 101 of the plastic color mixing machine. The downward-facing powder outlet 261 design facilitates the smooth entry of color powder into the mixing chamber 101, reduces the loss and scattering of color powder during the discharge process, and further improves the efficiency and accuracy of color powder conveying.

[0050] In some embodiments, the powder feeding mechanism 280 is detachably attached to the powder feeding base 210, and the powder feeding channel 260 is fixed to the powder feeding base 210 for positioning the powder feeding mechanism 280. Specifically, the end face of the powder feeding channel 260 located on the powder inlet side is configured to position the front positioning surface 262 of the powder feeding mechanism 280 in the insertion direction of the powder feeding screw 283.

[0051] In a further embodiment, a positioning space 270 is formed within the powder feeding base 210 to position the powder feeding mechanism 280 in the circumferential direction. The front positioning surface 262 and the positioning space 270 together limit the powder feeding mechanism 280 to a set position.

[0052] In a further embodiment, the powder feeding base 210 has a rear positioning member 212 that positions the powder feeding mechanism 280 in the retraction direction of the powder feeding screw 283. The rear positioning member 212 is detachably attached to the powder feeding base 210. The rear positioning member 212 can be detachably mounted on the powder feeding base 210 by means of bolts or other fixing methods. Its position and size can ensure reliable limiting of one side of the transmission seat 281 and prevent the transmission seat 281 from shifting in the horizontal direction.

[0053] In some embodiments, the powder feeding base 210 has a limiting plate 211 to restrict the downward movement of the transmission assembly 282. Specifically, the limiting plate 211 is configured to limit the bottom of the transmission base 281. The limiting plate 211 can be a metal plate fixed to the powder feeding base 210 by welding, bolting, or other means. Its height and position are precisely designed to match the shape and size of the bottom of the transmission base 281. When the transmission base 281 is installed in place, the limiting plate 211 and the color powder cylinder 220 form a stable vertical positioning, effectively preventing the transmission base 281 from moving in the vertical direction. Alternatively, the bottom of the transmission base 281 can be directly abutted against the powder feeding base 210 for limiting. By setting a limiting groove or protrusion structure on the powder feeding base 210 that matches the shape of the bottom of the transmission base 281, stable support and limiting of the transmission base 281 can be achieved.

[0054] In some embodiments, the powder feeding screw 283 includes a feeding section and a transmission section. The feeding section can be inserted into the powder feeding channel 260, and its outer surface is designed with a spiral feeding groove. When the feeding screw rotates, the color powder moves along the powder feeding channel 260 from the powder inlet to the powder outlet 261 under the pushing action of the spiral groove, thereby achieving stable powder feeding. The diameter and length of the feeding section are designed according to the size of the powder feeding channel 260 and the actual powder feeding requirements to ensure that the feeding section can cooperate with the powder feeding channel 260.

[0055] The transmission unit can be inserted into the transmission base 281 to connect with the transmission assembly 282 and rotate under the action of the transmission assembly 282. The end of the transmission unit is designed with a connection structure adapted to the output end of the transmission assembly 282, such as gear teeth or splines. Power is transmitted by meshing or cooperating with the gears or spline sleeves at the output end of the transmission assembly 282. When the transmission assembly 282 is driven by the motor 240, it can accurately transmit power to the transmission unit of the powder feeding screw 283, thereby driving the feeding unit to rotate in the powder feeding channel 260 to complete the task of conveying the color powder.

[0056] To achieve precise control and real-time monitoring of the powder feeding amount, in some embodiments, the powder feeding mechanism 280 further includes a detection module. The detection module includes a trigger 214, a detection element 213, and a control unit. The trigger 214 is connected to the transmission assembly 282 and can be connected to the end of the transmission part of the powder feeding screw 283. The trigger 214 can trigger the detection element 213 to generate a position signal at a set position. The control unit determines the number of rotations of the powder feeding screw 283 based on the position signal to determine the powder feeding amount, thereby accurately calculating the discharge amount from the powder outlet. In this embodiment, the detection element 213 can be a non-contact proximity switch, such as a Hall element, inductive sensor, capacitive sensor, or reed switch, or it can be a contact switch, such as a micro switch. When the detection element 213 is a Hall element, the trigger 214 is a magnet. When the detection element 213 is a micro switch, the trigger 214 is a toggle element. When a combination of a Hall element and a magnet is used, the Hall element is installed on the powder feeding base 210 near the end of the transmission part, and the magnet is fixed to the end of the transmission part. As the feeding screw rotates, the magnet also rotates. Each time the magnet passes the Hall element, the Hall element senses the change in the magnetic field, generating an electrical signal. By counting these electrical signals, the number of rotations of the feeding screw can be accurately measured. Similarly, when a combination of a microswitch and a toggle is used, the microswitch is mounted on the powder feeding base 210, and the toggle is fixed to the end of the transmission unit. As the feeding screw rotates, the toggle periodically triggers the microswitch. The electrical signal generated by the microswitch can also be used to calculate the number of rotations of the feeding screw, thereby achieving precise control and real-time monitoring of the powder feeding amount.

[0057] In practical applications, to improve powder feeding efficiency, the powder feeding screws 283 can include two screws arranged side by side. The two powder feeding screws 283 have the same structure and working principle; they rotate simultaneously within the powder feeding channel 260, enabling faster delivery of color powder from the inlet to the outlet. Since the two powder feeding screws 283 rotate the same number of times, only the end of the transmission section of one of the powder feeding screws 283 needs to be equipped with a detection element 213 and a trigger element 214 to measure the powder feeding amount of both screws 283. This simplifies the measurement structure and reduces costs while ensuring powder feeding efficiency.

[0058] The powder feeding mechanism 280 and the motor 240 are connected by a separate coupling mechanism 290. In some embodiments, the coupling mechanism 290 includes a first coupling member 291 disposed at the output end of the powder feeding drive motor 240 and a second coupling member 292 disposed at the input end of the transmission assembly 282. The first coupling member 291 and the second coupling member 292 are interlocked and separable. Specifically, the first coupling member 291 can be a cover with a spline groove, and the second coupling member 292 is the main body with a spline. When the powder feeding mechanism 280 needs to be installed, the spline of the second coupling member 292 is aligned with the spline groove of the first coupling member 291, and then the two are interlocked. The spline and spline groove fit tightly, achieving stable and reliable power coupling and ensuring that the power of the powder feeding drive motor 240 can be effectively transmitted to the powder feeding screw 283. When the powder feeding mechanism 280 needs to be cleaned or maintained, simply separate the first coupling member 291 and the second coupling member 292 to detach the powder feeding mechanism 280 from the powder feeding base 210. This allows for convenient and quick cleaning and maintenance of the powder feeding screw 283 and the powder feeding channel 260 without disassembling a large number of parts, greatly improving the maintenance efficiency of the equipment.

[0059] In some embodiments, a color powder receiving groove 21021 is provided on the powder cylinder seat 2102 for receiving color powder, and the discharge port 2212 is located at the bottom of the color powder receiving groove 21021, which is connected to the powder inlet of the powder feeding channel 260, so that the color powder can smoothly enter the powder feeding channel 260 through the discharge port 2212.

[0060] To facilitate the smooth feeding of pigment from the pigment cylinder 220 to the powder feeding channel 260, in some embodiments, a pusher impeller 223 is rotatably connected inside the pigment receiving tank 21021. The pusher impeller 223 is connected to the pigment cylinder seat 2102 via a pusher shaft 225. The top end of the pusher shaft 225 is detachably coupled to the output end of the pusher drive motor 250, and the bottom end is rotatably connected to the bottom of the pigment receiving tank 21021 via a bearing. The pusher drive motor 250 is mounted on the top of the pigment cylinder 220 via a bracket 230 fixed to the side of the pigment cylinder seat 2102. When the pusher drive motor 250 starts, its power is transmitted to the pusher impeller 223 through the pusher shaft 225, causing the pusher impeller 223 to rotate inside the pigment receiving tank 21021. The blades of the pusher impeller 223 are designed with a specific shape and angle, which can effectively push the color powder to the bottom of the color powder receiving tank 21021 during rotation, so that the color powder can smoothly enter the powder feeding channel 260 through the discharge port 2212, ensuring the continuous and stable conveying of the color powder.

[0061] To improve the rotational stability of the pusher impeller 223 and ensure smooth toner feeding, in some embodiments, a traction assembly 226 is also configured on the pusher shaft 225. The traction assembly 226 includes a horizontal traction member 2261 fixed to the top of the pusher shaft 225 and a vertical traction member 2262 connected to the end of the horizontal traction member 2261 and the end of the pusher impeller 223. The horizontal traction member 2261 and the vertical traction member 2262 are typically made of materials such as metal rods or high-strength plastic rods, and are fixedly connected to the pusher shaft 225 and the pusher impeller 223 by welding, bolting, or other methods. During the rotation of the pusher impeller 223, the traction assembly 226 can effectively limit the swaying and deviation of the pusher impeller 223, enhance the stability of the pusher impeller 223, and enable the pusher impeller 223 to operate more smoothly, thereby ensuring that the toner can be fed evenly and stably from the toner cartridge 220 to the toner feeding channel 260.

[0062] The working process or principle of this utility model is as follows:

[0063] In actual operation, the pigment is first loaded into the pigment cylinder 220, and the pigment receiving tank 21021 receives the accumulated pigment. The pusher drive motor 250 drives the pusher impeller 223 to rotate through the pusher shaft 225, pushing the pigment to the discharge port 2212 of the pigment receiving tank 21021. The pigment enters the powder inlet of the powder feeding channel 260 from the discharge port 2212.

[0064] The powder feeding drive motor 240 transmits power to the transmission component 282 of the powder feeding mechanism 280 through the coupling mechanism 290, driving the powder feeding screw 283 to rotate. The powder feeding screw 283 pushes the color powder from the powder inlet of the powder feeding channel 260 to the powder outlet 261, and then enters the mixing chamber 101 of the plastic color mixing machine through the powder outlet 261.

[0065] During the powder feeding process, the detection element 213 receives the trigger signal from the trigger element 214 and counts it. By measuring the number of rotations of the feeding screw, the output amount of the powder is calculated, thereby achieving precise control and real-time monitoring of the powder feeding amount.

[0066] When cleaning is required for the powder feeding channel 260 and the powder feeding screw 283, simply detach the powder feeding mechanism 280 from the receiving space 270 for easy cleaning and maintenance. After cleaning, reinstall the powder feeding mechanism 280 into the receiving space 270 to restore normal operation.

[0067] In summary, the color powder output device 200 of this utility model, through the ingenious design and coordinated operation of its various components, achieves stable delivery, precise control, and convenient and quick cleaning and maintenance of color powder. It effectively solves the problems of cleaning difficulties and inaccurate powder delivery control in traditional color powder output devices, improves the performance and reliability of the plastic color mixing machine 100, and has important practical application value and promotion significance.
