Technical Field

[0001] This utility model relates to the field of powder packaging technology, and in particular to a powder coating packaging machine. Background Technology

[0002] Powder coatings are a new type of coating that exists in powder form without solvents. They are environmentally friendly, efficient, and have excellent performance, making them widely used in the industrial coating field. With increasingly stringent environmental requirements, powder coatings, due to their environmental advantages, are being used more and more extensively in industries such as building materials, home appliances, and automobiles, leading to a continuously expanding market and a corresponding increase in demand for powder coating packaging machines.

[0003] Because the packaging can contains a large amount of powder, when the filling port of the existing powder coating packaging machine is opened, a large amount of powder accumulates at the discharge port, which can easily cause the powder to clog the discharge port and reduce packaging efficiency.

[0004] Therefore, a powder coating packaging machine is proposed to solve the above problems. Utility Model Content

[0005] In view of the problem that existing powder coating packaging machines cause a large amount of powder to accumulate at the discharge port when the filling port is opened, which can easily lead to powder blockage at the discharge port and reduce packaging efficiency, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a powder coating packaging machine, which includes a base with an internal cavity and a packaging can disposed on the top of the base. The top of the packaging can is provided with a feed inlet, and the feed inlet is provided with a detachable feed cover. The bottom of the packaging can is provided with a discharge pipe. The top of the packaging can is provided with a motor, and the output shaft of the motor is provided with a cam. A vertically moving unblocking rod is provided inside the packaging can. The top of the unblocking rod penetrates through the top of the packaging can. The top of the unblocking rod is provided with a fixing plate. The side of the fixing plate is rotatably provided with a roller. The roller cooperates with the cam. A side unblocking rod is provided on the unblocking rod located inside the packaging can.

[0007] Preferably, the side rod is an anchor-shaped structure with the tip pointing downwards.

[0008] Preferably, the bottom of the discharge pipe is located inside the base, the discharge pipe includes a discharge port at the bottom, and the discharge pipe is provided with an adjustment mechanism for controlling the opening and closing size of the discharge port.

[0009] Preferably, the adjustment mechanism includes a connecting plate fixed to the side wall of the discharge pipe and a servo electric cylinder fixed to the top of the base. The output end of the servo electric cylinder is provided with a receiving plate, the other side of the receiving plate is provided with an insert plate, and the connecting plate is provided with a slot for connecting to the insert plate.

[0010] Preferably, the size of the insert plate is larger than the discharge port.

[0011] Preferably, a pressure sensor is provided at the bottom of the base, a support plate is floating above the pressure sensor, and a packaging box is placed on the support plate.

[0012] Preferably, a support column is provided at the bottom of the base, a support sleeve is provided at the bottom of the support plate, the support sleeve is floatingly sleeved on the outside of the support column, a spring is provided on the outside of the support column, one end of the spring is fixed to the bottom of the base, and the other end is fixed to the bottom of the support sleeve.

[0013] Preferably, a fixing column is fixedly installed on the top of the base, and the other end of the fixing column is fixedly connected to the bottom of the packaging can.

[0014] The beneficial effects of this utility model are:

[0015] 1. By incorporating a motor, cam, roller, and unblocking rod, the discharge port is cleared, preventing powder from accumulating excessively and affecting the discharge speed when the port is open. The motor drives the cam to rotate, which in turn drives the roller. The fixed plate and unblocking rod connected to the roller reciprocate up and down, clearing the discharge port. An anchor-shaped side guide rod is installed on the unblocking rod; as the unblocking rod moves up and down, the side guide rod improves the flowability of powder within the packaging can.

[0016] 2. By setting up an adjustment mechanism to control the opening and closing size of the discharge port, the size of the discharge port can be adjusted, thereby adjusting the powder discharge speed. The servo electric cylinder can move a certain displacement each time, improving the adjustment accuracy.

[0017] 3. Quantitative packaging is achieved by setting up a floating support plate, pressure sensor, support column, support sleeve, and spring. Powder falls into the packaging box on the support plate, and as the amount of powder in the packaging box increases, the support plate moves downward. When the pressure sensor reaches the preset value, the signal is fed back to the servo cylinder, which causes the insert plate to quickly close the discharge port. Attached Figure Description

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Reference Figures 1 to 4 This invention provides a powder coating packaging machine, comprising a base 1 with an internal cavity and a packaging can 2 disposed on the top of the base 1. The top of the packaging can 2 is provided with a feed inlet 4, and a detachable feed cover 5 is provided on the feed inlet 4. The bottom of the packaging can 2 is provided with a discharge pipe 12. The top of the packaging can 2 is provided with a motor 6, and a cam 7 is provided on the output shaft of the motor 6. A vertically moving unblocking rod 10 is provided inside the packaging can 2, and the top of the unblocking rod 10 penetrates the top of the packaging can 2. A fixing plate 9 is provided on the top of the unblocking rod 10, and a roller 8 is rotatably disposed on the side of the fixing plate 9. The roller 8 cooperates with the cam 7. A side unblocking rod 11 is provided on the unblocking rod 10 located inside the packaging can 2.

[0027] Specifically, the base 1 has an internal cavity and one side is not closed. The packaging can 2 is placed on the top of the base 1. The base 1 also has a fixing column 3. The two ends of the fixing column 3 are fixed to the top of the base 1 and the bottom of the packaging can 2, respectively. The design of the fixing column 3 improves the support of the packaging can 2. The top of the packaging can 2 has a feed inlet 4. The top of the feed inlet 4 has a detachable feed cover 5. When adding powder, the feed cover 5 is opened and closed after adding. The bottom of the packaging can 2 has a discharge pipe 12. The inlet of the discharge pipe 12 is connected to the outlet of the packaging can 2.

[0028] Specifically, a drain rod 10 is installed inside the packaging can 2. The bottom of the drain rod 10 is located inside the discharge pipe 12, and the top of the drain rod 10 penetrates through the top of the packaging can 2. A fixing plate 9 is fixedly installed on the top of the drain rod 10 outside the packaging can 2. A rotating column is fixedly installed on one side of the fixing plate 9. A roller 8 is rotatably installed on the rotating column. A motor 6 is installed on the top of the packaging can 2. A cam 7 is installed on the output shaft of the motor 6. The cam 7 cooperates with the roller 8.

[0029] Understandably, when the motor 6 rotates, the cam 7 rotates as well, driving the roller 8 that works with it to move, which in turn causes the unblocking rod 10 to move up and down reciprocally, allowing the powder accumulated in the discharge pipe 12 to flow. This prevents the powder from accumulating in the discharge pipe 12 and clogging the discharge port, thus affecting the discharge speed and improving the discharge speed and smoothness.

[0030] Specifically, the unblocking rod 10 is located inside the packaging can 2 and is equipped with a side unblocking rod 11. The side unblocking rod 11 is a pointed anchor rod, and at least two sets of side unblocking rods 11 are arranged in the circumferential direction.

[0031] Understandably, when the side-through rod 11 moves up and down with the unblocking rod 10, the side-through rod 11 can "stir" the powder in the packaging can 2, improving the flowability of the powder; the anchor-shaped structure reduces the resistance when the side-through rod 11 descends.

[0032] Specifically, the discharge pipe 12 is equipped with an adjustment mechanism for controlling the size of the discharge port. The adjustment mechanism includes a connecting plate 15 fixed to the side wall of the discharge pipe 12 and a servo electric cylinder 13 fixed to the top of the base 1. The output end of the servo electric cylinder 13 is provided with a receiving plate 14, and the other side of the receiving plate 14 is provided with an insert plate 17. The connecting plate 15 is provided with a slot 16 that connects to the insert plate 17. The size of the insert plate 17 is larger than the size of the discharge port so that the discharge port can be completely closed. The servo electric cylinder 13 can move a certain displacement each time, thereby improving the adjustment accuracy.

[0033] Understandably, when material needs to be discharged, the servo cylinder 13 retracts, the insert plate 17 is pulled out from the slot 16, and a gap is formed between the insert plate 17 and the discharge port, from which the powder flows out; when the discharge is completed, the servo motor 6 pushes out, the insert plate 17 is inserted into the slot 16, and the insert plate 17 and the discharge port are closed.

[0034] In some embodiments, the regulating mechanism is a throttle valve located between the inlet and outlet of the discharge pipe 12; the throttle valve is regulated by a controller of an external device.

[0035] Specifically, a support plate 18 is floatingly installed at the bottom of the base 1, meaning the support plate 18 can move up and down. A pressure sensor 19 is fixedly installed at the bottom of the base 1, with its top sensing end contacting the bottom of the support plate 18. A packaging box 23 is placed on top of the support plate 18. The pressure sensor 19 and the servo cylinder 13 are also connected to the external controller. When the amount of powder in the packaging box 23 increases, the pressure of the packaging box 23 on the support plate 18 increases. When the preset pressure is reached, feedback is sent to the external controller, which then controls the servo cylinder 13 to quickly insert the insert plate 17 into the slot 16, closing the discharge port.

[0036] Specifically, a support column 20 is provided at the bottom of the base 1, and a support sleeve 21 is provided at the bottom of the support plate 18. The support sleeve 21 is floatingly fitted outside the support column 20. A spring 22 is provided outside the support column 20, with one end of the spring 22 fixed to the bottom of the base 1 and the other end fixed to the bottom of the support sleeve 21. This structure improves the supporting force on the support plate 18 and also acts as a buffer, thus extending the lifespan of the pressure sensor 19.

[0037] During use, the feed inlet 4 is opened, the powder is put into the packaging can 2, the feed cover 5 is then closed, and the servo cylinder 13 is started. According to the powder type, the servo cylinder 13 is controlled to pull the insert plate 17 out of the gap in the slot 16, thereby controlling the discharge speed. At the same time, the motor 6 rotates, and the cam 7 rotates with it, driving the roller 8 to move, thereby causing the unblocking rod 10 to move up and down to unblock the powder in the discharge pipe 12 and improve the smoothness of the discharge. The powder gradually falls into the packaging box 23, and the packaging box 23 applies pressure to the support plate 18. The pressure sensor 19 senses the pressure in real time. When the pressure reaches the preset value, the signal of the pressure sensor 19 is fed back to the external controller. The external controller controls the servo cylinder 13 to quickly insert the insert plate 17 into the slot 16, close the discharge port, and complete one packaging.
