Description

Technical Field

[0001] This utility model relates to the field of foam adhesive production technology, and in particular to a bubble elimination device in the die-cutting process of foam adhesive. Background Technology

[0002] Foam adhesive is a widely used bonding material in many fields, renowned for its excellent adhesion and cushioning properties. It is primarily used to replace traditional fixing methods such as screws and rivets, resulting in smoother, more aesthetically pleasing product surfaces, simpler operation, better sealing, longer-lasting effects, and easy assembly and disassembly.

[0003] In the process of die-cutting foam adhesive, multiple raw materials are usually stirred and mixed. However, existing stirring and mixing devices generally do not have a device to eliminate air bubbles in the raw materials, resulting in a large number of air bubbles in the raw materials, which has a certain impact on the subsequent production of foam adhesive. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology. By rotating the toothed ring, the rotating tube and multiple stirring rods are rotated to agitate the raw materials, causing gas to be discharged from the raw materials. Then, through the connection between the connecting plate and the rotating tube and the sliding connection between the rotating tube and the two sleeves, the rotating tube carries multiple stirring rods to generate vibration in the tank. The vibration breaks up the air bubbles in the raw materials, thus providing a bubble elimination device for foam adhesive die-cutting.

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

[0006] A bubble elimination device for foam die-cutting includes a tank. The lower end of the tank has multiple circumferentially arranged support rods.

A rotating tube is slidably connected between two of the sleeves. Multiple equally spaced stirring rods are arranged on the outer wall of the rotating tube, and all stirring rods are connected to the rotating tube. A heating mechanism for heating the rotating tube and stirring rods is located at the upper end of the tank, and a lifting mechanism for raising and lowering the rotating tube is also located at the upper end of the tank.

[0007] Preferably, the heating mechanism includes a hot air blower installed at the upper end of the tank, the output end of the hot air blower is provided with a connecting pipe, the end of the connecting pipe is provided with a rotary joint, the rotary joint is connected to the upper end of the rotating pipe, and the outer wall of the connecting pipe is provided with a corrugated pipe.

[0012] The beneficial effects of this utility model are:

[0013] 1. By rotating the toothed ring, the rotating tube and multiple stirring rods are driven to rotate, which agitates the raw materials and causes gas to be discharged from the raw materials. Then, through the connection between the connecting plate and the rotating tube and the sliding connection between the rotating tube and the two sleeves, the rotating tube carries multiple stirring rods to generate vibration in the tank, which breaks up the air bubbles in the raw materials.

[0014] 2.

[0021] Reference Figure 1-3 A bubble elimination device for foam die-cutting includes a tank 1. The lower end of the tank 1 has multiple circumferentially arranged support rods 2. The upper end of the tank 1 has a feed pipe 4, and the lower end of the tank 1 has a discharge pipe 3. Sleeves 13 pass through both the upper and lower ends of the tank 1. A rotating pipe 14 is slidably connected between two sleeves 13. Multiple equally spaced stirring rods 19 are arranged on the outer wall of the rotating pipe 14, and all stirring rods 19 are connected to the rotating pipe 14. The upper end of the tank 1 is equipped with a heating element for heating the rotating pipe 14 and the stirring rods 19. The heating mechanism includes a hot air blower 17 installed at the upper end of the tank body 1. The output end of the hot air blower 17 is provided with a connecting pipe, and the end of the connecting pipe is provided with a rotary joint 16, which is connected to the upper end of the rotating pipe 14. The outer wall of the connecting pipe is provided with a corrugated pipe 18. By generating heat in both the rotating pipe 14 and the outer wall of multiple stirring rods 19, the raw material is heated through heat transfer between the materials, thereby achieving the effect of eliminating air bubbles and avoiding the generation of too many air bubbles in the raw material, which would affect the subsequent production of foam adhesive.

[0022] The upper end of the tank body 1 is provided with a lifting mechanism for raising and lowering the rotating tube 14. The lifting mechanism includes a rotating rod rotatably connected to the upper end of the tank body 1. The outer wall of the rotating rod is provided with a reciprocating screw area 8. The outer wall of the reciprocating screw area 8 is provided with a screw sleeve 9. The outer wall of the screw sleeve 9 is provided with a connecting plate 10. The connecting plate 10 is connected to the rotating tube 14.

[0023] A power motor 11 is provided at the upper end of the connecting plate 10. The output shaft of the power motor 11 passes through the connecting plate 10 and is provided with a gear 12. The outer wall of the rotating tube 14 is provided with a gear ring 15 that meshes with the gear 12. By rotating the gear ring 15, the rotating tube 14 and multiple stirring rods 19 are driven to rotate, which agitates the raw material and causes gas to be discharged from the raw material. Then, through the connection between the connecting plate 10 and the rotating tube 14 and the sliding connection between the rotating tube 14 and the two sleeves 13, the rotating tube 14 carries multiple stirring rods 19 to generate vibration in the tank 1, which breaks up the air bubbles in the raw material.

[0024] The upper end of the tank body 1 is provided with a mounting plate 5, which is L-shaped. The upper end of the mounting plate 5 is provided with a drive motor 7, and the upper end of the reciprocating screw area 8 is connected to the end of the output shaft of the drive motor 7.

[0025] A limiting rod 6 is provided between the mounting plate 5 and the tank body 1. The limiting rod 6 passes through the connecting plate 10 and is slidably connected to it.

[0026] In use, various raw materials are fed into the tank 1 through the feed pipe 4. The drive motor 7, power motor 11, and hot air blower 17 are started, causing the drive motor 7 to rotate the reciprocating screw section 8. Under the limiting action of the reciprocating screw section 8, the screw sleeve 9, and the limiting rod 6 on the connecting plate 10, the screw sleeve 9 moves the connecting plate 10 up and down reciprocally. Through the connection between the connecting plate 10 and the rotating tube 14, and the sliding connection between the rotating tube 14 and the two sleeves 13, the rotating tube 14, carrying multiple stirring rods 19, vibrates inside the tank 1. The vibration breaks up the air bubbles in the raw materials. At the same time, the power motor 11 drives the gear 12 to rotate. The meshing of the gear 12 and the gear ring 15 causes the gear ring 15 to rotate, which in turn drives the rotating tube 14 and multiple stirring rods 19 to rotate, agitating the raw materials and expelling the gas from them. Meanwhile, the hot air generated by the hot air generator 17 enters the rotating tube 14 through the connecting pipe, causing the rotating tube 14 and the outer walls of the multiple stirring rods 19 to generate heat. Through heat transfer between the materials, the raw materials are heated, thereby eliminating the bubbles and preventing the formation of too many bubbles in the raw materials, which would affect the subsequent production of foam adhesive.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
