Packaging device for thermosetting powder preparation

Abstract

This utility model discloses a packaging device for preparing thermosetting powder, including a chassis with a feeding funnel on the chassis. A clamping assembly is located vertically below the feeding funnel on the chassis. A switch assembly for controlling the amount of thermosetting powder fed is also provided on the chassis. The clamping assembly opens the opening of the packaging bag receiving the thermosetting powder and fixes it vertically below the feeding funnel. The switch assembly controls the feeding of thermosetting powder into the packaging bag. When the piston moves away from the feeding pipe, it removes the obstruction to the thermosetting powder, allowing the powder to fall into the packaging bag through the vertical pipe. When the packaging bag is almost full, the piston returns to its original position, again obstructing the feeding of the thermosetting powder to prevent further feeding. Simultaneously, the first and second clamping blocks move closer together, squeezing the opening of the packaging bag to complete the sealing. The overall structure is simple, can be operated by one person, and improves the efficiency of thermosetting powder packaging.

[0002] Thermosetting powder coatings are environmentally friendly, efficient, and durable coating materials widely used in industrial corrosion protection and decoration. With technological advancements, their applications are continuously expanding to low-temperature substrates and areas with special functional requirements.

[0003] Currently, after the thermosetting powder is produced, workers need to use carriers to put the powder into packaging bags to complete the packaging. However, this requires two people to work together, which wastes manpower and time. Utility Model Content

[0004] The purpose of this invention is to provide a packaging device for the preparation of thermosetting powders, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a packaging device for preparing thermosetting powder, comprising a housing, a feeding funnel on the housing, a clamping assembly on the housing and located vertically below the feeding funnel, and a switch assembly on the housing for controlling the feeding quantity of thermosetting powder.

[0006] The clamping assembly opens the bag opening of the packaging bag containing thermosetting powder and fixes it vertically below the feeding funnel. The switching assembly controls the feeding of thermosetting powder into the packaging bag.

[0007] Preferably, the switch assembly includes a base disposed on the upper surface of the chassis, and a first telescopic cylinder is disposed on the base via a support plate, wherein a piston rod is connected to the power output end of the first telescopic cylinder.

[0008] Preferably, the feeding end of the feeding funnel is provided with a feeding pipe, and the feeding pipe is provided with a connecting pipe at the end facing the first telescopic cylinder, and the piston rod extends into the connecting pipe and is provided with a piston.

[0009] Preferably, the chassis is connected to a vertical tube via a clamping and fixing plate on the side facing the packaging bag, and the upper surface of the vertical tube extends outward with an extension portion.

[0010] Preferably, the clamping assembly includes a second telescopic cylinder disposed inside the chassis, the power output end of the second telescopic cylinder extending to the outside of the chassis through a strip groove and connected to a first clamping block, the first clamping block being disposed on a connecting rod, the other end of the connecting rod being connected to a third telescopic cylinder, and the power output end of the third telescopic cylinder being connected to the second clamping block.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] To improve the packaging efficiency of thermosetting powders, refer to Figure 1 , Figure 2 and Figure 3 As shown, the device includes a housing 1, on which a feeding hopper 2 is mounted. A clamping assembly is mounted on the housing 1 and positioned vertically below the feeding hopper 2. The housing 1 also includes a switch assembly for controlling the amount of thermosetting powder fed. The clamping assembly opens the opening of the packaging bag containing the thermosetting powder and fixes it vertically below the feeding hopper 2. The switch assembly controls the feeding of the thermosetting powder into the packaging bag. The thermosetting powder to be packaged is poured into the feeding hopper 2, and the opening of the packaging bag is turned outwards. The two outward-turned sides are respectively fixed to a first clamping block 12 and a second toothed block by fixing strips 15. As the second telescopic cylinder 11 is driven, the first clamping block 12 and the second clamping block 13 move away from each other, causing the bag opening to open. The first telescopic cylinder 4 is then activated to drive the piston rod 5, which moves within the connecting pipe 7, causing the piston 8 to move away from the feeding pipe 6. This removes the obstruction to the thermosetting powder, allowing the thermosetting powder to fall into the bag through the vertical pipe 9. When the bag is almost full, the piston 8 returns to its original position, blocking the thermosetting powder again to prevent further feeding. Simultaneously, the first clamping block 12 and the second clamping block 13 move closer together, squeezing the bag opening to complete the sealing process. The overall structure is simple.

[0022] To facilitate packaging after packing, please refer to... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the switching assembly includes a base 3 disposed on the upper surface of the housing 1. A first telescopic cylinder 4 is mounted on the base 3 via a support plate. The power output end of the first telescopic cylinder 4 is connected to a piston rod 5, which pushes a piston 8, allowing the piston 8 to move from the connecting pipe 7 into the feeding pipe 6 of the feeding funnel 2 to block the thermosetting powder, thereby controlling the feeding of the thermosetting powder. The feeding funnel 2 has a feeding pipe 6 at its feeding end, and a connecting pipe 7 is provided at the end of the feeding pipe 6 facing the first telescopic cylinder 4. The piston rod 5 extends into the connecting pipe 7 and a piston 8 is disposed therein. The piston 8 is adapted to the diameter of the feeding pipe 6 to achieve blocking. A vertical pipe 9 is connected to the side of the housing 1 facing the packaging bag via a clamping and fixing plate. An extension 10 extends outward from the upper surface of the vertical pipe 9, increasing the receiving range during feeding and preventing the thermosetting powder from scattering to other locations during the feeding process, thus reducing losses. The clamping assembly includes a second telescopic cylinder 11 disposed inside the housing 1. The power output end of the second telescopic cylinder 11 extends to the outside of the housing 1 through a strip groove and is connected to a first clamping block 12. The first clamping block 12 is disposed on a connecting rod. The other end of the connecting rod is connected to a third telescopic cylinder 16. The power output end of the third telescopic cylinder 16 is connected to a second clamping block 13. The first clamping block 12 and the second clamping block 13 are mounted on the connecting rod through a movable sleeve. When the packaging bag is filled with thermosetting powder, the power output ends of the second telescopic cylinder 11 and the third telescopic cylinder 16 push the first clamping block 12 and the second clamping block 13. Through the sliding of the movable sleeve, the first clamping block 12 and the second clamping block 13 move closer to each other. During this process, the sealing strip inside the packaging bag can be removed. The advancement of the first clamping block 12 and the second clamping block 13 can make the bag openings contact each other and complete the sealing. An independent space for placing a packaging bag is provided between the first clamping block 12 and the second clamping block 13, facilitating the placement of the packaging bag and allowing it to receive the thermosetting powder. Several serrated grooves 14 are centrally located on the opposite side of the first clamping block 12 and the second clamping block 13, and fixing strips 15 are provided on the upper surface of the first clamping block 12 and the second clamping block 13. These fixing strips 15 are used to open and fix the opening of the packaging bag, facilitating the loading of the thermosetting powder. It should be noted that the packaging bag is existing technology and has internal adhesive strips, which will not be described further here. After the first clamping block 12 and the second clamping block 13 press the opening of the packaged bag into contact, the two sides of the fixing strips 15 can be removed, thereby removing the packaging bag.

[0023] In use, the thermosetting powder to be packaged is poured into the feeding funnel 2, and the opening of the packaging bag is turned outward. The two outward sides are fixed to the first clamping block 12 and the second toothed block by the fixing strip 15 respectively. With the driving of the second telescopic cylinder 11 and the third telescopic cylinder 16, the first clamping block 12 and the second clamping block 13 move away from each other, so that the opening of the packaging bag is open. The first telescopic cylinder 4 is activated to drive the piston rod 5, so that the piston rod 5 moves in the connecting pipe 7, driving the piston 8 away from the feeding pipe 6, and removing the obstruction of the thermosetting powder. At this time, the thermosetting powder will fall into the packaging bag through the vertical pipe 9. When the packaging bag is about to be full, the piston 8 returns to its position, blocking the thermosetting powder again to prevent further feeding. At the same time, the first clamping block 12 and the second clamping block 13 move closer to each other, squeezing the opening of the packaging bag to complete the sealing.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
