Description

Technical Field

[0001] This utility model relates to the field of plastic processing equipment technology, and in particular to a color powder and color masterbatch switching feeding device. Background Technology

[0002] In the plastics processing industry, color powder or masterbatch is typically added to give plastic products different colors. Color powder has advantages such as low cost and flexible color mixing, but it can easily generate dust during use, posing a hazard to the working environment and the health of operators. Masterbatch, on the other hand, has advantages such as ease of use and environmental friendliness, but its cost is relatively high. Therefore, in actual production, it is sometimes necessary to switch between color powder and masterbatch supply according to different production needs.

[0003] However, most of the feeding devices in related technologies can only supply color powder or color masterbatch. To switch between the two, it is often necessary to manually change the feeding equipment or make complex adjustments. This not only increases the labor intensity of operators, but also leads to low production efficiency, and it is also difficult to guarantee the accuracy and stability of the feeding. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for switching between color powder and color masterbatch, so as to solve the problem that existing feeding devices are difficult to switch between color powder and color masterbatch in a convenient and efficient manner.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A color powder and masterbatch switching feeding device includes a color powder hopper, a masterbatch hopper, and a mixing tank. Both the color powder hopper and the masterbatch hopper are located on top of the mixing tank. A switching feeding mechanism is provided between the color powder hopper, the masterbatch hopper, and the mixing tank. The switching feeding mechanism includes two conveying pipes and a spherical shell. A feeding pipe is fixedly connected to the mixing tank. The two conveying pipes are respectively fixedly connected to the bottom of the color powder hopper and the masterbatch hopper, and are fixedly connected to both sides of the spherical shell. A cover is fixedly connected to the top of the spherical shell. A switching component is provided between the cover and the spherical shell. A controller is fixedly connected to the front of the mixing tank.

[0007] In a preferred embodiment of this invention, the switching assembly includes a drive motor fixedly connected to one side of the cover and a rotating shaft rotatably connected to the top of the spherical shell. A drive shaft is fixedly connected to the output shaft of the drive motor. A driving bevel gear is fixedly connected to one end of the drive shaft. A driven bevel gear is fixedly connected to the top end of the rotating shaft. The driving bevel gear and the driven bevel gear mesh with each other. A ball valve is fixedly connected to the bottom end of the rotating shaft. A common discharge port is fixedly connected between one side and the bottom of the ball valve.

[0008] In a preferred embodiment of this invention, a bearing is fixedly connected to the top of the spherical shell, and the rotating shaft is fixedly sleeved inside the inner ring of the bearing.

[0009] As a preferred embodiment of this utility model, through holes are provided on both sides of the spherical shell, the through holes are connected to the lower end of the corresponding conveying pipe, and the discharge port is connected to the corresponding through hole.

[0010] As a preferred embodiment of this invention, the top of the mixing box is fixedly connected to two support legs, and the two support legs are respectively fixedly connected to the bottom of the color powder hopper and the color masterbatch hopper.

[0011] As a preferred embodiment of the present invention, the mixing tank is provided with a stirring and mixing mechanism, the stirring and mixing mechanism including a stirring motor fixedly connected to one side of the mixing tank, a stirring shaft fixedly connected to the output shaft of the stirring motor, and several stirring vertical rods fixedly connected to the top and bottom of the stirring shaft.

[0012] As a preferred embodiment of this invention, a common stirring crossbar is fixedly connected between two adjacent stirring vertical rods.

[0013] As a preferred embodiment of this utility model, a feeding hopper is fixedly connected to one side of the mixing box, and a discharge pipe is fixedly connected to the bottom of one side of the mixing box, with a control valve installed on the discharge pipe.

[0014] In this utility model, a color powder and color masterbatch switching feeding device is described. When color masterbatch is needed for feeding, the controller drives the motor to rotate. The drive motor drives the drive shaft and the active bevel gear to rotate. The active bevel gear drives the driven bevel gear and the rotating shaft to rotate. The rotating shaft drives the ball valve to rotate 180 degrees, so that the discharge port is connected to the right conveying pipe. At the same time, the discharge port continues to be connected to the feeding pipe, while the left conveying pipe is disconnected from the feeding pipe. The color masterbatch can then be conveyed from the color masterbatch hopper through the right conveying pipe to the discharge port and the feeding pipe, and finally enter the mixing box.

[0015] In this utility model, a color powder and color masterbatch switching feeding device is described. Conversely, when it is necessary to switch to color powder feeding, the drive motor rotates in the reverse direction, causing the ball valve to rotate 180 degrees in reverse, so that the discharge port is connected to the left conveying pipe, while the right conveying pipe is disconnected from the discharge port. At this time, the color powder is conveyed from the color powder hopper to the mixing box through the left conveying pipe. When no feeding is required, the drive motor rotates the discharge port to a position where it is not connected to the two conveying pipes. The plastic raw material is poured in from the feed hopper, and the stirring motor drives the stirring shaft, stirring vertical rod and stirring horizontal rod to rotate, thereby stirring and mixing the plastic raw material and color powder or color masterbatch. The mixed material is discharged from the discharge pipe.

[0016] This utility model has a reasonable structural design. By setting up a switching feeding mechanism, the switching feeding of color powder and color masterbatch can be realized quickly and conveniently under the control of the controller. There is no need for manual replacement of feeding equipment or complex adjustments, which reduces the labor intensity of operators, reduces downtime during the feeding switching process, makes the production process more continuous, and thus improves production efficiency.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A color powder and color masterbatch switching feeding device includes a color powder hopper 203, a color masterbatch hopper 216, and a mixing tank 1. The color powder hopper 203 and the color masterbatch hopper 216 are both located on the top of the mixing tank 1. A switching feeding mechanism 2 is provided between the color powder hopper 203, the color masterbatch hopper 216, and the mixing tank 1. The switching feeding mechanism 2 includes two conveying pipes 204 and a spherical shell 202. A feeding pipe 201 is fixedly connected between the spherical shell 202 and the mixing tank 1. The two conveying pipes 204 are respectively fixedly connected to the bottom of the color powder hopper 203 and the color masterbatch hopper 216. The two conveying pipes 204 are fixedly connected to both sides of the spherical shell 202. A cover 206 is fixedly connected to the top of the spherical shell 202. A switching component is provided between the cover 206 and the spherical shell 202. A controller 6 is fixedly connected to the front side of the mixing tank 1.

[0024] Furthermore, refer to Figures 1-3 The switching assembly includes a drive motor 205 fixedly connected to one side of the cover 206 and a rotating shaft 210 rotatably connected to the top of the spherical shell 202. A drive shaft 211 is fixedly connected to the output shaft of the drive motor 205. A drive bevel gear 212 is fixedly connected to one end of the drive shaft 211. A driven bevel gear 213 is fixedly connected to the top end of the rotating shaft 210. The drive bevel gear 212 and the driven bevel gear 213 mesh with each other. A ball valve 208 is fixedly connected to the bottom end of the rotating shaft 210. A discharge port 209 is fixedly connected between one side and the bottom of the ball valve 208.

[0025] Using the above scheme: When color masterbatch is needed for feeding, the controller 6 drives the motor 205 to rotate. The motor 205 drives the drive shaft 211 and the active bevel gear 212 to rotate. The active bevel gear 212 drives the driven bevel gear 213 and the rotating shaft 210 to rotate. The rotating shaft 210 drives the ball valve 208 to rotate 180 degrees, connecting the discharge port 209 to the right conveying pipe 204. At the same time, the discharge port 209 continues to be connected to the feeding pipe 201, while the left conveying pipe 204 is disconnected from the feeding pipe 201. This allows the color masterbatch to pass through the color masterbatch hopper 216. The right-side conveying pipe 204 delivers the material to the discharge port 209 and the feeding pipe 201, eventually entering the mixing box 1. Conversely, when switching to pigment feeding, the drive motor 205 rotates in the reverse direction, causing the ball valve 208 to rotate 180 degrees in reverse, connecting the discharge port 209 with the left-side conveying pipe 204, while disconnecting the right-side conveying pipe 204 from the discharge port 209. At this time, pigment is delivered from the pigment hopper 203 to the mixing box 1 through the left-side conveying pipe 204. When no material is being supplied, the drive motor 205 rotates the discharge port 209 to a position where it is not connected to either of the two conveying pipes 204.

[0026] Furthermore, a bearing 214 is fixedly connected to the top of the spherical shell 202, and the rotating shaft 210 is fixedly sleeved in the inner ring of the bearing 214, which can support the rotating shaft 210 and make its rotation more stable.

[0027] Furthermore, through holes 215 are provided on both sides of the spherical shell 202. The through holes 215 are connected to the lower end of the corresponding conveying pipe 204, and the discharge port 209 is connected to the corresponding through hole 215, so as to facilitate the connection between the discharge port 209 and the corresponding conveying pipe 204.

[0028] Furthermore, the top of the mixing box 1 is fixedly connected to two support legs 207. The two support legs 207 are fixedly connected to the bottom of the color powder hopper 203 and the color masterbatch hopper 216 respectively, which can stably support and fix the color powder hopper 203 and the color masterbatch hopper 216.

[0029] Furthermore, refer to Figure 1 and Figure 4 The mixing tank 1 is equipped with a mixing mechanism 3. The mixing mechanism 3 includes a mixing motor 31 fixedly connected to one side of the mixing tank 1. A mixing shaft 32 is fixedly connected to the output shaft of the mixing motor 31. Several mixing vertical rods 33 are fixedly connected to the top and bottom of the mixing shaft 32. The same mixing horizontal rod 34 is fixedly connected between two adjacent mixing vertical rods 33.

[0030] Using the above method: the plastic raw material is poured into the feed hopper 4, and the stirring motor 31 drives the rotation of the stirring shaft 32, the stirring vertical rod 33 and the stirring horizontal rod 34, thereby stirring and mixing the plastic raw material and color powder or color masterbatch evenly. The mixed material is discharged from the discharge pipe 5.

[0031] Furthermore, a feed hopper 4 is fixedly connected to one side of the mixing box 1, and a discharge pipe 5 is fixedly connected to the bottom of one side of the mixing box 1. A control valve is installed on the discharge pipe 5 to facilitate material feeding and discharging.

[0032] In this invention, when color masterbatch is needed for feeding, the controller 6 drives the motor 205 to rotate. The motor 205 drives the drive shaft 211 and the active bevel gear 212 to rotate. The active bevel gear 212 drives the driven bevel gear 213 and the rotating shaft 210 to rotate. The rotating shaft 210 drives the ball valve 208 to rotate 180 degrees, connecting the discharge port 209 to the right-side conveying pipe 204. At the same time, the discharge port 209 continues to be connected to the feeding pipe 201, while the left-side conveying pipe 204 is disconnected from the feeding pipe 201. This allows the color masterbatch to be discharged from the color masterbatch hopper 216. The material is conveyed through the right-side conveying pipe 204 to the discharge port 209 and the feeding pipe 201, and finally enters the mixing box 1. Conversely, when it is necessary to switch to color powder feeding, the drive motor 205 rotates in the reverse direction, causing the ball valve 208 to rotate 180 degrees in reverse, so that the discharge port 209 is connected to the left-side conveying pipe 204, while the right-side conveying pipe 204 is disconnected from the discharge port 209. At this time, the color powder is conveyed from the color powder hopper 203 to the mixing box 1 through the left-side conveying pipe 204. When no material is being supplied, the drive motor 205 rotates the discharge port 209 to a position where it is not connected to either of the two conveying pipes 204.

[0033] Plastic raw materials are poured into the feed hopper 4, and the stirring motor 31 drives the rotation of the stirring shaft 32, stirring vertical rod 33 and stirring horizontal rod 34, thereby stirring and mixing the plastic raw materials and color powder or color masterbatch. The mixed material is discharged from the discharge pipe 5.
