Description

Technical Field

[0001] This invention relates to the field of painting tools technology, and in particular to an automatic extrusion device for art paints. Background Technology

[0002] Art students need to use a variety of paints when doing watercolor painting. They squeeze the tubes of paint onto the palette to mix colors. However, when students squeeze the paint from the tubes, their hands are easily stained with paint, which will make the paint tubes dirty. Moreover, the workload of students squeezing out the paint one by one is quite large. Therefore, it is necessary to design an automatic paint squeezing device.

[0003] Referring to patent application number CN201410313874.2, a tubular pigment extruder is disclosed, comprising a housing for holding the pigment tube and an extrusion device and a collection device disposed within the housing. The extrusion device includes a roller assembly I and a roller assembly II, each comprising two vertically arranged, parallel rollers with a compression gap between them. Gears meshing with each other are respectively disposed at the same end of the two rollers in roller assembly I. A handle driving the gears is fixed to one of the gears through the side wall of the housing. The width of the compression gap II in roller assembly II is smaller than the compression gap I in roller assembly I. The collection device is a rotating shaft with a spring clamp. A pulley is disposed at one end of the rotating shaft and on the handle. The handle drives the rotating shaft to rotate via a belt. This invention, through the arrangement of the extruder structure and the connection relationships of its various components, improves the pigment extrusion rate, reduces pigment residue in the tube, and minimizes waste through the cooperation of different components.

[0004] Based on the above patent search, current pigment extruders still have the following two drawbacks in use:

[0005] First, the current paint tubes lack a refilling device. Once the paint inside the tube is used up, it cannot be replenished, and the tube can only be discarded, resulting in a waste of resources.

[0006] Secondly, the nozzle at the front of the paint tube cannot rotate flexibly, making it impossible to control the spray direction, which causes paint to easily fall outside the student's palette. Summary of the Invention

[0007] In view of this, the present invention provides an automatic extrusion device for art paints. The middle part of the nozzle is an elastic hose, which allows the middle part of the nozzle to be bent at will and adjust the discharge direction of the nozzle. An addition tube is also fixedly installed on the outer end face of the paint tube. When there is not much paint in the paint tube, the stopper plate at the top of the addition tube can be removed, and then new paint can be injected into the addition tube to replenish the paint in the paint tube.

[0008] The present invention provides an automatic extrusion device for art paints, which includes: a device box;

[0009] The device box has six support blocks fixedly installed on its lower end face. The upper end of the support block is a cylindrical structure, and the lower end of the support block is a suction cup. The left and right side plates of the device box have U-shaped handles fixedly installed in the middle of their upper end faces. The handles make it easy for workers to pick up the device box.

[0010] The device box has two drive motors. One drive motor is fixedly installed on the outer end face of the right side plate of the device box. The front end of the drive motor is connected to a drive screw. The other end of the drive screw is rotatably connected to the inner end face of the left side plate of the device box.

[0011] The pigment tube has a cylindrical front end and a flat rear end, with a spray nozzle fixedly mounted on the front end.

[0012] The push plate has a rectangular plate structure as its main body, and a trapezoidal limiting clamp is installed at each end of the push plate. Threaded holes are opened on the surface of the push plate.

[0013] Two fixing plates are symmetrically installed on the left and right ends of the push plate. The lower end face of the fixing plate is flush with the lower end face of the push plate. Three through holes are opened on the surface of the fixing plate.

[0014] The lifting plate has a long strip-shaped structure. Two side baffles are symmetrically installed on the lower end of the lifting plate, and a rotating roller is rotatably connected between the two side baffles.

[0015] Furthermore, a partition plate is fixed in the middle of the device box, and the two ends of the partition plate are fixedly connected to the left and right side plates of the device box respectively. Track grooves are opened on the inner end faces of the front and rear side plates of the device box, and track grooves are also opened on the front and rear end faces of the partition plate respectively.

[0016] Furthermore, the push plate is slidably mounted inside the track groove by limiting clamps at both ends, and the push plate is threadedly connected to the drive screw.

[0017] Furthermore, two control switches are fixedly installed on the outer end face of the device box. The control switches are located directly below the drive motor and are electrically connected to the drive motor.

[0018] Furthermore, three fixing rods are fixedly installed on the upper end face of the lifting plate, and the fixing rods are slidably engaged in the through holes of the fixing plate.

[0019] Furthermore, a compression spring is sleeved on the outside of the fixing rod, with the upper end of the compression spring fixedly connected to the fixing plate and the lower end face of the compression spring fixedly connected to the lifting plate.

[0020] Furthermore, the front end of the nozzle is a conical structure, and the middle part of the nozzle is an elastic tube. The nozzle is connected to the pigment tube. The elastic tube in the middle part of the nozzle allows the middle part of the nozzle to bend freely, which can adjust the discharge direction of the nozzle and allow the pigment to drip accurately onto the palette.

[0021] Furthermore, an addition tube is fixedly installed on the outer end face of the pigment tube. The main body of the addition tube has an L-shaped structure, and a stopper plate is provided at the upper inlet of the addition tube. Resistance strips are evenly installed on the outer end face of the stopper plate.

[0022] This invention provides an automatic extrusion device for art paints, which has the following advantages:

[0023] 1. By connecting the drive screw and the push plate with a thread, the drive screw can drive the push plate forward during rotation. When the push plate moves forward, the two rotating rollers can squeeze the pigment tube, thereby squeezing the pigment inside the pigment tube. At the same time, the limiting clamps at both ends of the push plate are slidably locked inside the track groove, so that when the push plate moves back and forth, the two limiting clamps can play a limiting role and prevent the push plate from swaying left and right.

[0024] 2. The flexible hose in the middle of the nozzle allows for free bending, adjusting the discharge direction. The tapered front end of the nozzle facilitates the discharge of pigment onto the student's palette. An L-shaped adder is fixedly installed on the outer end of the pigment tube. When the pigment in the tube is low, the stopper at the top of the adder can be removed, and new pigment can be injected into the adder to replenish the pigment in the tube.

[0025] 3. The three fixed rods on the upper surface of the lifting plate are slidably locked into the through holes on the surface of the fixed plate, so that the fixed rods can move up and down along the through holes. Furthermore, a compression spring is sleeved on the outside of the fixed rod. The compression spring is located between the fixed plate and the lifting plate. Under the action of the compression spring, a downward force can be applied to the lifting plate. At the same time, it can also increase the squeezing force of the rotating roller on the pigment tube, so that all the pigment inside the pigment tube can be squeezed out.

[0026] 4. The device box is divided into two parts by a partition plate fixed inside. There is a paint tube on each side of the partition plate, and the two paint tubes are filled with different paints, which can facilitate students' painting work. The lower end of the support block is a suction cup. When the device box is placed on the table, the suction cup can fit tightly with the table, which can increase the stability of the device box on the table. Attached Figure Description

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present invention.

[0042] Example 1: Please refer to Figures 1 to 9 As shown:

[0043] This invention provides an automatic extrusion device for art paints, including a device box 1;

[0044] Six support blocks 102 are fixedly installed on the lower end face of the device box 1. The upper end of the support block 102 is a cylindrical structure, and the lower end of the support block 102 is a suction cup. A U-shaped handle 101 is fixedly installed in the middle of the upper end face of the left and right side plates of the device box 1. The handle 101 makes it easy for students to pick up the device box 1. Two control switches 402 are fixedly installed on the outer end face of the device box 1. The control switches 402 are located directly below the drive motor 4 and are electrically connected to the drive motor 4. During use, the control switches 402 can control the opening and closing of the drive motor 4.

[0045] Two drive motors 4 are provided. The drive motor 4 is fixedly installed on the outer end face of the right side plate of the device box 1. The front end of the drive motor 4 is connected to the drive screw 401. The other end of the drive screw 401 is rotatably connected to the inner end face of the left side plate of the device box 1.

[0046] The pigment tube 5 has a cylindrical front end and a flat rear end. A spray nozzle 501 is fixedly installed on the front end of the pigment tube 5.

[0047] The push plate 6 has a rectangular plate structure as its main body. A trapezoidal limiting clamp 601 is installed at each end of the push plate 6. Threaded holes are opened on the surface of the push plate 6.

[0048] There are two fixed plates 7 installed symmetrically. The fixed plates 7 are fixedly installed on the left and right ends of the push plate 6. The lower end surface of the fixed plate 7 is flush with the lower end surface of the push plate 6. The surface of the fixed plate 7 has three through holes.

[0049] The lifting plate 8 has a long strip-shaped structure. Two side baffles 801 are symmetrically installed on the lower end of the lifting plate 8, and a rotating roller 9 is rotatably connected between the two side baffles 801.

[0050] The push plate 6 is slidably mounted inside the track groove 3 by the limiting clamps 601 at both ends. The push plate 6 is threadedly connected to the drive screw 401. In use, the pigment tube 5 is located at the bottom of the device box 1. When it is necessary to squeeze the pigment inside the pigment tube 5 outward, the drive motor 4 can be started. The drive motor 4 can drive the drive screw 401 to rotate. Through the threaded connection between the drive screw 401 and the push plate 6, the drive screw 401 can drive the push plate 6 to move forward during rotation. When the push plate 6 moves forward, the two rotating rollers 9 can squeeze the pigment tube 5, thereby squeezing the pigment inside the pigment tube 5, so that the pigment can be sprayed out from the nozzle 501 at the front end of the pigment tube 5.

[0051] The nozzle 501 has a tapered front end and a flexible middle section. It connects to the pigment tube 5. An additive tube 502 is fixedly installed on the outer end of the pigment tube 5. The additive tube 502 has an L-shaped main body and a stopper plate 5021 at its upper inlet. Resistance strips are evenly installed on the outer end of the stopper plate 5021. During use, the flexible middle section of the nozzle 501 allows it to bend freely, adjusting the discharge direction. The outer end of the pigment tube 5 is also fixed. The device is equipped with an L-shaped filling tube 502. When there is not much paint left in the paint tube 5, the stopper plate 5021 at the top of the filling tube 502 can be removed, and new paint can be injected into the filling tube 502. The filling tube 502 is connected to the paint tube 5, so the paint in the filling tube 502 will enter the paint tube 5 to replenish it. The outer end face of the stopper plate 5021 is evenly equipped with resistance strips. The resistance strips can increase the friction between the student's hand and the stopper plate 5021, making it easier to pick up the stopper plate 5021.

[0052] Example 2: This invention provides an automatic extrusion device for art paints, based on Example 1, such as... Figures 1-9 As shown, it also includes: a lifting plate 8, three fixing rods 802 are fixedly installed on the upper end surface of the lifting plate 8, the fixing rods 802 are slidably locked in the through holes of the fixing plate 7, and a compression spring 10 is sleeved on the outside of the fixing rods 802. The upper end of the compression spring 10 is fixedly connected to the fixing plate 7, and the lower end surface of the compression spring 10 is fixedly connected to the lifting plate 8.

[0053] The technical effects achieved by adopting the above scheme are as follows: two fixed plates 7 are fixedly installed on the left and right sides of the push plate 6. The surface of the fixed plate 7 has three through holes, and the three fixed rods 802 on the upper end of the lifting plate 8 are slidably engaged in the through holes on the surface of the fixed plate 7, so that the fixed rods 802 can move up and down along the through holes. A side baffle 801 is installed at each end of the lifting plate 8. The rotating roller 9 is rotatably connected between the two side baffles 801. When the push plate 6 moves forward, the rotating roller 9 can also rotate forward on the upper end of the pigment tube 5, thereby squeezing the pigment inside the pigment tube 5. A compression spring 10 is also sleeved on the outside of the fixed rod 802. The compression spring 10 is located between the fixed plate 7 and the lifting plate 8. Under the action of the elastic force of the compression spring 10, a downward force can be applied to the lifting plate 8. At the same time, it can also increase the squeezing force of the rotating roller 9 on the pigment tube 5, so that all the pigment inside the pigment tube 5 can be squeezed out.

[0054] Example 3: This invention provides an automatic extrusion device for art paints, based on Example 1, such as... Figures 1-9 As shown, it also includes: a partition plate 2. The partition plate 2 is fixed in the middle of the device box 1. The two ends of the partition plate 2 are fixedly connected to the left and right side plates of the device box 1 respectively. The inner end faces of the front and rear side plates of the device box 1 are provided with track grooves 3. The front and rear end faces of the partition plate 2 are also provided with track grooves 3 respectively.

[0055] The technical effects achieved by adopting the above scheme are as follows: A partition plate 2 is fixedly installed inside the device box 1, which divides the device box 1 into two parts. A paint tube 5 is provided at each of the left and right ends of the partition plate 2. The two paint tubes 5 are filled with different paints, which can facilitate students' painting work. The limiting clamps 601 at both ends of the push plate 6 are slidably locked inside the track groove 3, so that when the push plate 6 moves back and forth, the two limiting clamps 601 can play a limiting role and prevent the push plate 6 from swinging left and right.

[0056] The specific usage and function of this embodiment: In this invention, the pigment tube 5 is located at the bottom of the device box 1. When it is necessary to squeeze the pigment inside the pigment tube 5 outward, the drive motor 4 can be started. The drive motor 4 can drive the drive screw 401 to rotate. Through the threaded connection between the drive screw 401 and the push plate 6, the drive screw 401 can drive the push plate 6 to move forward during rotation. When the push plate 6 moves forward, the two rotating rollers 9 can squeeze the pigment tube 5, thereby squeezing the pigment inside the pigment tube 5, so that the pigment can be sprayed out from the nozzle 501 at the front end of the pigment tube 5. The middle part of the nozzle 501 is an elastic hose, so that the middle part of the nozzle 501 can be bent at will. The nozzle 501 can be adjusted to change the discharge direction. An addition tube 502 is fixedly installed on the outer end of the pigment tube 5. The addition tube 502 has an L-shaped structure. When there is not much pigment in the pigment tube 5, the stopper plate 5021 at the top of the addition tube 502 can be removed, and new pigment can be injected into the addition tube 502. The addition tube 502 is connected to the pigment tube 5, so the pigment in the addition tube 502 will enter the pigment tube 5 to replenish it. The stopper plate 5021 has evenly distributed resistance strips on its outer end. These resistance strips increase the friction between the student's hand and the stopper plate 5021, making it easier to pick up the stopper plate 5021. Two fixing plates 7 are fixedly installed on the left and right sides of the push plate 6. The surface of the lifting plate 8 has three through holes, and the three fixing rods 802 on the upper end face of the lifting plate 8 are slidably engaged in the through holes on the surface of the fixing plate 7, so that the fixing rods 802 can move up and down along the through holes. A side baffle 801 is installed at each end of the lifting plate 8, and a rotating roller 9 is rotatably connected between the two side baffles 801. When the lifting plate 6 moves forward, the rotating roller 9 can also rotate forward on the upper end face of the pigment tube 5, thereby squeezing the pigment inside the pigment tube 5. A compression spring 10 is also sleeved on the outside of the fixing rod 802. The compression spring 10 is located between the fixing plate 7 and the lifting plate 8. Under the action of the elastic force of the compression spring 10, a downward force can be applied to the lifting plate 8, and at the same time, it can also increase the rotation of the rotating roller 9. The squeezing force on the paint tube 5 allows all the paint inside the paint tube 5 to be squeezed out. The device box 1 is fixedly installed with a partition plate 2, which divides the device box 1 into two parts. There is a paint tube 5 at each end of the partition plate 2. The two paint tubes 5 are filled with different paints, which can facilitate students' painting work. The limiting clamps 601 at both ends of the push plate 6 are slidably locked in the track groove 3, so that when the push plate 6 moves back and forth, the two limiting clamps 601 can play a limiting role to prevent the push plate 6 from swaying left and right. The lower end of the support block 102 is divided into suction cups. When the device box 1 is placed on the table, the suction cups can fit tightly with the table, which can increase the stability of the device box 1 on the table.
