Description

Technical Field

[0001] This application relates to the field of plastics processing, and in particular to a color powder metering control device for a color powder machine. Background Technology

[0002] A color powder machine refers to a machine that feeds a fixed amount of color powder from a color powder container and a fixed amount of plastic from a plastic container into a mixing tank and mixes them evenly to process plastics of various colors. However, during the operation of the color powder machine, the operator needs to take a fixed amount of color powder from the color powder container and a fixed amount of plastic from the plastic container and pour them into the mixing tank in sequence for mixing to achieve uniform feeding of plastics.

[0003] The pigment in the pigment container needs to be manually measured, which makes it easy for the amount of pigment added to be off, resulting in uneven feeding of plastic and thus reducing the processing quality of the plastic. Utility Model Content

[0004] To address the issue of potential deviations in pigment input, this application provides a pigment metering control device for a pigment machine.

[0005] This application provides a color powder quantitative control device for a color powder machine, which adopts the following technical solution:

[0006] A color powder metering control device for a color powder machine includes a base and a metering component. The surface of the base facing the discharge end of the color powder container has a feeding trough for color powder to enter. The metering component includes a push plate. The surface of the base has a sliding cavity for the push plate to slide, and the sliding cavity is connected to the feeding trough. The surface of the push plate facing the feeding trough has a preparatory trough for color powder to enter, and the preparatory trough penetrates the surface of the push plate. The surface of the base facing the feeding end of the mixing tank has a discharge trough for color powder to be discharged, and the discharge trough is connected to the sliding cavity.

[0007] By adopting the above technical solution, when a quantitative amount of color powder needs to be supplied to the mixing tank, the push plate is driven to slide along the inner wall of the sliding cavity towards the direction of the feed chute. The feed chute is connected to the preparatory chute. The color powder in the color powder tank enters the preparatory chute through the feed chute, filling the preparatory chute. The color powder content in the preparatory chute is equal to the color powder content required for plastic coloring. The push plate is then driven to slide along the inner wall of the sliding cavity towards the direction of the discharge chute. The preparatory chute is connected to the discharge chute. The inner wall of the preparatory chute abuts against the color powder and drives the color powder closer to the discharge chute. The preparatory chute penetrates the push plate surface. The color powder in the preparatory chute enters the feeding end of the mixing tank through the discharge chute, realizing the quantitative feeding of color powder in the mixing tank, ensuring the accurate input of color powder, and making the plastic in the mixing tank uniformly colored, thereby improving the processing quality of plastic.

[0008] Optionally, the metering component further includes a power component connected to the surface of the base, with the driving end of the power component passing through the surface of the base and connected to the surface of the push plate. The power component drives the push plate to slide back and forth within the sliding cavity.

[0009] By adopting the above technical solution, the power component is installed on the surface of the base, and the driving end of the power component passes through the surface of the base and is connected to the surface of the push plate, driving the push plate to slide back and forth on the inner wall of the sliding cavity. There is no need for the staff to manually control the sliding of the push plate, which improves the ease of use of the color powder quantitative control device of the color powder machine.

[0010] Optionally, the push plate includes a fixed part and an adjusting part. One end of the fixed part is connected to the drive end of the power component, and the other end of the fixed part is provided with an adjusting flow channel for the adjusting part to slide. The adjusting flow channel passes through the outer wall of the fixed part. The preparatory groove is located between the fixed part and the adjusting part. When the adjusting part slides along the inner wall of the adjusting flow channel in a direction away from the power component, the opening of the preparatory groove increases.

[0011] By adopting the above technical solution, when the staff needs to adjust the content of pigment powder in the mixing tank, the preparation tank is located between the fixed part and the adjustment part, which drives the adjustment part to slide along the inner wall of the sliding flow channel, thereby realizing the directional change of the opening of the preparation tank. This enables the pigment powder quantitative control device of the pigment powder machine to accurately control the input of pigment powder of different contents, thereby improving the ease of use of the pigment powder quantitative control device of the pigment powder machine.

[0012] Optionally, the push plate further includes an adjusting member, which is connected to the surface of the fixed part. The driving end of the adjusting member passes through the surface of the fixed part and is connected to the adjusting part. The adjusting member drives the adjusting part to slide on the inner wall of the adjusting channel.

[0013] By adopting the above technical solution, the driving end of the adjusting component passes through the surface of the fixed part and is connected to the adjusting part, driving the adjusting part to slide on the inner wall of the adjusting channel, thereby achieving precise control over the size of the preparatory groove opening, ensuring accurate input of color powder content, and thus improving the processing quality of plastics.

[0014] Optionally, the surface of the seat is connected to an air inlet pipe for connecting to an external air pump. The end of the air inlet pipe passes through the surface of the seat and is located in the discharge groove, and the inlet of the air inlet pipe in the discharge groove faces the sliding cavity.

[0015] By adopting the above technical solution, the air inlet on the surface of the seat is connected to the air outlet of the external air pump. When the push plate slides along the inner wall of the sliding cavity toward the discharge trough, the preparation trough is connected to the discharge trough. The external air pump drives air to enter the discharge trough through the air inlet. The air inlet in the discharge trough faces the sliding cavity. The air in the discharge trough impacts the inner wall of the preparation trough, causing the residual pigment on the inner wall of the preparation trough to fall off, ensuring that the pigment does not easily remain on the inner wall of the preparation trough, and further improving the accurate control of pigment content.

[0016] Optionally, the power component is a power cylinder, which is connected to the surface of the base. The piston rod axis of the power cylinder and the sliding direction of the push plate are parallel to each other. The end of the piston rod of the power cylinder passes through the surface of the base and is connected to the surface of the fixed part.

[0017] By adopting the above technical solution, the end of the piston rod of the power cylinder passes through the surface of the seat and is connected to the surface of the fixed part, which drives the fixed part to slide on the inner wall of the sliding cavity, making it less likely for the fixed part to deviate on the inner wall of the sliding cavity, thereby improving the accuracy of the operation of the color powder quantitative control device of the color powder machine.

[0018] Optionally, the adjusting component is an adjusting bolt, the surface of the fixing part is provided with a threaded groove one for threaded connection of the adjusting bolt, the surface of the adjusting part is provided with a threaded groove two for threaded connection of the adjusting bolt, and the end of the adjusting bolt passes through the threaded groove one and is threadedly connected to the inner wall of the threaded groove two.

[0019] By adopting the above technical solution, the end of the adjusting bolt is threaded through a groove and threaded to the inner wall of the second groove, driving the adjusting bolt to rotate and causing the adjusting part to slide on the inner wall of the adjusting channel, making it less likely for the adjusting part to deviate from the inner wall of the adjusting channel, thereby improving the precise control of the color powder input of the color powder quantitative control device of the color powder machine.

[0020] Optionally, the surface of the base is provided with a limiting cavity into which the discharge end of the color powder bucket is embedded. The limiting cavity is connected to the feeding groove, and the inner wall of the limiting cavity abuts against the outer peripheral surface of the color powder bucket to form a limiting position.

[0021] By adopting the above technical solution, when the discharge end of the color powder bucket is embedded in the limiting cavity, the outer circumference of the color powder bucket abuts against the inner wall of the limiting cavity to form a limit, making it difficult for the color powder bucket to detach from the base, thereby improving the connection stability between the color powder bucket and the base.

[0022] Optionally, the seat is connected to an elastic arc strip, with each end of the elastic arc strip corresponding to the inner wall of the discharge groove. The fixing part presses the outer arc surface of the elastic arc strip against the surface of the discharge groove and drives the elastic arc strip to deform. When the power cylinder drives the fixing part to approach the discharge groove and the discharge groove is connected to the preparation groove, the clamping effect of the fixing part on the elastic arc strip disappears, and the outer arc surface of the elastic arc strip rebounds and embeds into the preparation groove, scraping off the color powder on the inner wall of the preparation groove.

[0023] By adopting the above technical solution, the two ends of the elastic arc strip along its length are embedded one-to-one into the inner walls of the discharge trough, forming a fixed structure. The fixed part presses against the outer arc surface of the elastic arc strip and drives the elastic arc strip to deform. When the power cylinder drives the fixed part to approach the discharge trough and the discharge trough is connected to the preparation trough, the pressing effect of the fixed part on the elastic arc strip disappears. The outer arc surface of the elastic arc strip rebounds and embeds into the preparation trough, scraping away the color powder on the inner wall of the preparation trough. This makes it difficult for color powder with a certain viscosity to stick to the inner wall of the preparation trough, thereby further improving the accuracy of quantitative feeding of color powder.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The push plate setting allows the color powder in the preheating tank to enter the feeding end of the mixing tank through the discharge chute, realizing the quantitative feeding of color powder in the mixing tank, ensuring the accurate input of color powder, so that the plastic in the mixing tank is uniformly colored, thereby improving the processing quality of plastic.

[0026] 2. The power component allows the push plate to slide back and forth within the sliding cavity, eliminating the need for manual control of the push plate and improving the ease of use of the color powder metering control device.

[0027] 3. The setting of the fixing part and the adjusting part realizes the directional change of the slot opening of the preparation tank, so that the color powder quantitative control device of the color powder machine can accurately control the input of different contents of color powder, thereby improving the ease of use of the color powder quantitative control device of the color powder machine.

[0035] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0036] This application discloses a color powder quantity control device for a color powder machine. (Refer to...) Figure 1 and Figure 2 The color powder metering control device for the color powder machine includes a base 1 and a metering component 2. The top surface of the base 1 has a limiting cavity 11 into which the discharge end of the color powder bucket is embedded. The inner wall of the limiting cavity 11 is pressed against the outer circumference of the color powder bucket to form a limit, thereby connecting the color powder bucket with the base 1. The inner wall of the limiting cavity 11 facing the discharge end of the color powder bucket has a feeding groove 12. The color powder in the color powder bucket enters the feeding groove 12 through the discharge end. The bottom surface of the base 1 has a discharge groove 13 for discharging color powder. The opening of the discharge groove 13 faces the feeding end of the mixing tank. The metering component 2 is installed on the base 1. The metering component 2 drives the color powder in the feeding groove 12 to enter the mixing tank in a metered manner from the discharge groove 13, thereby realizing the metered feeding of color powder in the mixing tank, ensuring the accurate input of color powder, and making the plastic in the mixing tank uniformly colored, thereby improving the processing quality of the plastic.

[0037] Reference Figure 2 and Figure 3The metering component 2 includes a pusher plate 21 and a power component 22. A sliding cavity 14 is provided on the side wall of the base 1 for the pusher plate 21 to slide. The sliding cavity 14 connects the feed chute 12 and the discharge chute 13. The surface of the pusher plate 21 abuts against the inner wall of the sliding cavity 14 and separates the feed chute 12 and the discharge chute 13. A preparatory groove 211 is provided on the surface of the pusher plate 21 facing the feed chute 12. The preparatory groove 211 penetrates the surface of the pusher plate 21 along its depth direction. When the pusher plate 21 slides towards the feed chute 12, the preparatory groove 211... 1. The feed trough 12 is connected, and the color powder in the color powder bucket enters the preparation trough 211 through the feed trough 12. The color powder fills the preparation trough 211, and the color powder content in the preparation trough 211 is equal to the color powder content required for coloring the plastic in the mixing tank. The push plate 21 is driven to slide along the inner wall of the sliding cavity 14 towards the discharge trough 13. The discharge trough 13 is connected to the preparation trough 211. The color powder in the preparation trough 211 enters the mixing tank through the discharge trough 13 under the influence of its own gravity, so as to achieve precise feeding of color powder in the mixing tank.

[0038] Reference Figure 2 and Figure 3 The power component 22 is installed between the base 1 and the push plate 21. The power component 22 can push the push plate 21 to slide along the inner wall of the sliding cavity 14. The power component 22 is a power cylinder 221, which is fixed on the surface of the base 1. The surface of the base 1 facing the piston rod of the power cylinder 221 is provided with a relief cavity 15 for the extension and retraction of the piston rod of the power cylinder 221. The relief cavity 15 is connected to the sliding cavity 14. The axis of the piston rod of the power cylinder 221 and the sliding direction of the push plate 21 are parallel to each other. The end of the piston rod of the power cylinder 221 is embedded in the relief cavity 15 and fixed on the surface of the push plate 21. When the piston rod of the power cylinder 221 extends, it drives the push plate 21 to slide along the inner wall of the sliding cavity 14 towards the direction of the discharge chute 13. When the piston rod of the power cylinder 221 retracts, it drives the push plate 21 to slide along the inner wall of the sliding cavity 14 towards the direction of the feed chute 12.

[0039] As an alternative, refer to 2 and... Figure 4 The power component 22 includes a power motor 222 and a reciprocating lead screw 223. The power motor 222 is fixed to the surface of the base 1 by bolts. The motor axis of the power motor 222 and the sliding direction of the push plate 21 are parallel to each other. One end of the reciprocating lead screw 223 is coaxially fixed to the motor shaft of the power motor 222. The other end of the reciprocating lead screw 223 passes through the surface of the base 1 and is embedded in the sliding cavity 14. The push plate 21 is threaded to the outer wall of the reciprocating lead screw 223. When the power motor 222 runs, it drives the push plate 21 to slide along the axis of the reciprocating lead screw 223 on the inner wall of the sliding cavity 14.

[0040] Reference Figure 2 and Figure 3The push plate 21 includes a fixing part 212, an adjusting part 213, and an adjusting component 214. In this embodiment, both the fixing part 212 and the adjusting part 213 are plate bodies. One end of the fixing part 212 in the length direction is fixed to the piston rod surface of the power cylinder 221. The other end of the fixing part 212 in the length direction is provided with an adjusting channel 2121 for the adjusting part 213 to slide. The length direction of the adjusting channel 2121 is parallel to the axis of the piston rod of the power cylinder 221. The adjusting channel 2121 passes through both sides of the fixing part 212 in the height direction. The preparation groove 211 is located between the fixing part 212 and the adjusting part 213. The size of the opening of the preparation groove 211 is adjusted by the adjusting part 213 sliding on the inner wall of the adjusting channel 2121, so that the color powder quantitative control device of the color powder machine can accurately control the input of color powder with different contents, thereby improving the versatility of the color powder quantitative control device of the color powder machine.

[0041] Reference Figure 2 and Figure 3 An adjusting member 214 is connected between the fixed part 212 and the adjusting part 213. The adjusting member 214 can drive the adjusting part 213 to slide on the inner wall of the adjusting channel 2121. The adjusting member 214 is an adjusting bolt 2141. The surface of the fixed part 212 away from the power cylinder 221 has a threaded groove 2122 for threaded connection of the adjusting bolt 2141. The depth direction of the threaded groove 2122 is parallel to the piston rod axis of the power cylinder 221. The threaded groove 2122 penetrates the fixed part 2121 along its own depth direction. The outer wall of the fixed part 212 and the surface of the adjusting part 213 facing the first threaded groove 2122 are provided with a second threaded groove 2131 for the adjusting bolt 2141 to be threadedly connected. The end of the adjusting bolt 2141 passes through the first threaded groove 2122 and is threadedly connected to the inner wall of the second threaded groove 2131. When it is necessary to adjust the size of the opening of the preparatory groove 211, the adjusting bolt 2141 is rotated, which drives the adjusting part 213 to slide on the inner wall of the adjusting channel 2121, so as to achieve precise adjustment of the size of the opening of the preparatory groove 211.

[0042] As an alternative, refer to Figure 2 and Figure 5 The adjusting component 214 includes an adjusting cylinder 2142, which is fixed to the surface of the fixing part 212 away from the power cylinder 221 by bolts. The piston rod end of the adjusting cylinder 2142 passes through the surface of the fixing part 212 and is fixed to the surface of the adjusting part 213. The piston rod axis of the adjusting cylinder 2142 and the piston rod axis of the power cylinder 221 are parallel to each other. When the piston rod of the adjusting cylinder 2142 extends, it drives the adjusting part 213 to slide along the adjusting flow channel 2121 towards the fixing part 212, and the opening of the preparation groove 211 becomes smaller. When the piston rod of the adjusting cylinder 2142 retracts, it drives the adjusting part 213 to slide along the adjusting flow channel 2121 away from the fixing part 212, and the opening of the preparation groove 211 becomes larger.

[0043] As an alternative, refer to Figure 2 and Figure 6 The adjusting component 214 includes an adjusting motor 2143 and an adjusting screw 2144. The adjusting motor 2143 is fixed to the surface of the fixing part 212 away from the power cylinder 221 by bolts. The piston rod end of the adjusting motor 2143 passes through the surface of the fixing part 212 and is coaxially fixed to the end of the adjusting screw 2144. The motor axis of the adjusting motor 2143 and the piston rod axis of the power cylinder 221 are parallel to each other. The adjusting part 213 is threaded to the outer wall of the adjusting screw 2144. When the adjusting motor 2143 drives the adjusting screw 2144 to rotate, it drives the adjusting part 213 to slide along the inner wall of the adjusting channel 2121, so as to achieve precise control of the size of the opening of the preparatory groove 211.

[0044] Reference Figure 2 and Figure 3 An air inlet pipe 3 is installed on the side wall of the base 1. The end of the air inlet pipe 3 protruding from the surface of the base 1 is for the installation of an external air pump. The other end of the air inlet pipe 3 passes through the surface of the base 1 and is located in the discharge trough 13. The opening of the air inlet pipe 3 in the discharge trough 13 faces the sliding cavity 14. When the push plate 21 slides along the sliding cavity 14 toward the discharge trough 13, the preparation trough 211 is connected to the discharge trough 13. The color powder in the preparation trough 211 enters the mixing tank through the discharge trough 13 under the influence of its own gravity. At the same time, the external air pump drives air to enter the discharge trough 13 through the air inlet pipe 3. The opening of the air inlet pipe 3 faces the sliding cavity 14. The air in the discharge trough 13 impacts the inner wall of the preparation trough 211 and causes the residual color powder on the inner wall of the preparation trough 211 to fall off, so that the color powder is not easy to remain on the inner wall of the preparation trough 211, thereby improving the accuracy of the color powder feeding in the mixing tank.

[0045] Reference Figure 2 The seat 1 is equipped with an elastic arc strip 4. In this embodiment, the elastic arc strip 4 is made of spring steel and has a certain deformation capacity. The elastic arc strip 4 includes an arc-shaped part 41 and two connecting parts 42. The two ends of the arc-shaped part 41 are fixed to the ends of the connecting parts 42 in the arc direction. The ends of the two connecting parts 42 away from the arc-shaped part 41 are embedded in the inner walls of the discharge groove 13 facing each other. The fixing part 212 presses the outer arc surface of the arc-shaped part 41 towards the surface of the discharge groove 13 and drives the arc-shaped part 41 towards the surface of the discharge groove 13. The deformation is closer to the discharge trough 13; when the power cylinder 221 drives the fixing part 212 to slide along the inner wall of the sliding cavity 14 towards the discharge trough 13, and the discharge trough 13 is connected to the preparation trough 211, the squeezing effect of the fixing part 212 on the arc-shaped part 41 disappears, the outer arc surface of the arc-shaped part 41 rebounds and embeds into the preparation trough 211 and scrapes off the color powder on the inner wall of the preparation trough 211, so that the sticky color powder is not easy to adhere to the inner wall of the preparation trough 211, thereby improving the accuracy of the color powder discharge in the preparation trough 211.

[0046] The implementation principle of the color powder quantitative control device for a color powder machine according to an embodiment of this application is as follows: When a quantitative amount of color powder needs to be supplied to the mixing tank, the adjusting bolt 2141 is rotated, causing the adjusting part 213 to slide along the inner wall of the adjusting channel 2121. The preparatory trough 211 is located between the adjusting part 213 and the fixed part 212, so that the volume of the preparatory trough 211 matches the volume of color powder required by the mixing tank, thereby achieving precise control of the color powder feeding. The piston rod of the power cylinder 221 retracts, causing the fixed part 212 to slide along the inner wall of the sliding cavity 14 towards the direction close to the feeding trough 12. The feeding trough 12 is connected to the preparatory trough 211. The color powder in the color powder tank enters the preparatory trough 211 through the feeding trough 12, filling the preparatory trough 211. The content is equal to the amount of pigment powder required for coloring the plastic in the mixing tank. The piston rod of the power cylinder 221 extends, driving the fixed part 212 to slide along the inner wall of the sliding cavity 14 towards the discharge trough 13. The discharge trough 13 is connected to the preparation trough 211. The pigment powder in the preparation trough 211 enters the mixing tank through the discharge trough 13 under its own gravity. At the same time, the external air pump drives air to enter the discharge trough 13 through the air inlet pipe 3. The inlet of the air inlet pipe 3 faces the sliding cavity 14. The air in the discharge trough 13 impacts the inner wall of the preparation trough 211 and carries away the pigment powder remaining in the preparation trough 211, realizing the directional feeding of pigment powder in the mixing tank, ensuring the accurate input of pigment powder content, so that the plastic in the mixing tank is uniformly colored, thereby improving the processing quality of the plastic.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
