Description

Technical Field

[0001] This invention relates to the field of filter manufacturing, and more particularly to a dispensing device for filter processing. Background Technology

[0002] A filter is an accessory that uses filter paper to filter impurities or gases. Filters are a major component of a car engine. The main function of a filter is to filter and remove impurities from the air, engine oil, or fuel to prevent these impurities from entering the engine. If impurities enter the engine, they can easily lead to deterioration of engine performance and shorten its lifespan. During the manufacturing process of filters, an adhesive dispensing device is used to seal the ports.

[0003] Patent application number CN202322749169.4 discloses a dispensing machine for air filter production and processing, including a dispensing base. A clamping mechanism is slidably connected to the top of the dispensing base via a limiting groove. The clamping mechanism is used to clamp the air filter. The clamping mechanism includes a clamping base slidably connected to the dispensing base. Two clamping blocks are slidably connected to the top of the clamping base. A buffer pad is fixedly connected to one side of each clamping block. A placement groove is provided on the top of the clamping base, and a collection box is disposed inside the placement groove. The air filter is clamped by the two clamping blocks of the clamping mechanism, and then dispensing is performed on the filter. However, this type of dispensing device can only apply glue to a single air filter at a time, which greatly reduces production efficiency.

[0004] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dispensing device for filter processing.

[0006] This invention can be achieved through the following technical solutions:

[0007] This invention discloses a dispensing device for filter processing, comprising a base plate, a feeding conveyor belt disposed above the base plate and driven to rotate by a feeding motor, a support plate fixed to the base plate at the end of the feeding conveyor belt, rotating shafts symmetrically disposed on both sides above the support plate, each rotating shaft having a screw fixed to it and driven to rotate by a corresponding positioning motor, a top plate fixed above the support plate, a fixing plate disposed below the top plate, multiple cylinders fixed to the top plate, the piston rod ends of each cylinder being fixed to the fixing plate, rotating blocks evenly disposed on the fixing plate and rotatably connected to the fixing plate, each rotating block having a glue tube fixed to it, and each rotating block being driven to rotate by a rotary motor. The filters to be dispensed are placed sequentially on the feeding conveyor belt. The feeding motor drives the conveyor belt to rotate, and the filters move towards the support plate. When the filters reach the screw position, the positioning motor drives the screws to rotate. Both screws rotate. When the spiral grooves on the screws reach the filter position, the rear filter pushes the front filter forward. The foremost filter enters the spiral grooves of both screws and, through the screw rotation, moves the filter forward. When the spiral grooves at the starting position of the screws close again, the next filter enters the spiral grooves of both screws and is transported forward. This cycle continues until all filters are fixed below the hose. The screws stop, the cylinder starts, the piston rod on the cylinder extends, the fixing plate descends, and the hose descends with the fixing plate to the designated position. During dispensing, pressure is applied to the piston inside the dispensing tube, causing it to descend and force adhesive through the dispensing needle below the tube to the filter. Simultaneously, a rotary motor drives rotating blocks, causing the dispensing tube to rotate with the rotating shaft. The dispensing needle applies a ring of adhesive to the corresponding position on the filter. After dispensing, a cylinder is activated, extending the piston rod and raising the dispensing tube. The positioning motor then drives the rotating shaft again, causing the dispensed filter to move with the screw. After the dispensed filter separates from the screw, multiple filters in the next batch arrive at their corresponding dispensing tubes, creating a cyclical process. This device can perform dispensing operations on filters, and multiple filters can be dispensed simultaneously, greatly improving dispensing efficiency.

[0008] Preferably, limit rods are symmetrically arranged on both sides above the feeding conveyor belt. The limit rods ensure that the filter accurately enters between the two screws and prevent the filter from falling off the feeding conveyor belt.

[0009] Preferably, each of the rotating shafts has a slave pulley fixed at its end, and the output end of the positioning motor has a master pulley fixed thereon. The master pulley is connected to the corresponding slave pulley via a synchronous belt.

[0010] Preferably, each of the rotating blocks is fixed with a driven gear, adjacent driven gears mesh with each other, and the output end of the rotary motor is fixed with a master gear, which meshes with one of the driven gears.

[0011] Preferably, a receiving conveyor belt is also provided above the bottom plate at the end of the support plate, and the receiving conveyor belt is driven to rotate by a receiving motor. The filter that has been dispensed reaches the position of the receiving conveyor belt and is collected as the receiving conveyor belt rotates.

[0012] Compared with existing technologies, the present invention has the following advantages:

[0013] 1. This device can perform glue dispensing operations on filters, and can perform glue dispensing operations on multiple filters at one time, which greatly improves the glue dispensing efficiency of filters.

[0014] 2. By setting a screw, the individual filters can be separated and transported forward. Attached Figure Description

[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0019] Example 1:

[0020] like Figure 1As shown, this embodiment discloses a dispensing device for filter processing, comprising a base plate 1, a feeding conveyor belt 2 above the base plate 1, the feeding conveyor belt 2 being driven to rotate by a feeding motor 3, a support plate 6 being fixed on the base plate 1 at the end of the feeding conveyor belt 2, a rotating shaft 7 being symmetrically arranged on both sides above the support plate 6, a screw 8 being fixed on each of the rotating shafts 7, the rotating shafts 7 being driven to rotate by a corresponding positioning motor 12, a top plate 13 being fixed above the support plate 6, a fixing plate 15 being arranged below the top plate 13, a plurality of cylinders 14 being fixed on the top plate 13, the piston rod ends of the cylinders 14 being fixed on the fixing plate 15, a rotating block 16 being evenly arranged on the fixing plate 15 and rotatably connected to the fixing plate 15, a glue tube 17 being fixed on each of the rotating blocks 16, and the rotating blocks 16 being driven to rotate by a rotating motor 19. The filters 5 to be dispensed are placed sequentially on the feeding conveyor belt 2. The feeding motor 3 drives the feeding conveyor belt 2 to rotate, and the filters 5 move towards the support plate 6. When the filters 5 reach the position of the screw 8, the positioning motor 12 drives the screw 8 to rotate. Both screws 8 rotate. When the spiral groove on the screw 8 rotates to the position of the filter 5, the rear filter 5 pushes the front filter 5 to move. The frontmost filter 5 enters the spiral groove of the two screws 8 and moves forward through the rotation of the screws 8. When the spiral groove at the starting position of the screw 8 closes again, the next filter 5 enters the spiral groove of the two screws 8 again and is transported forward. This cycle continues. When all the filters 5 are fixed below the hose 17, the screws 8 stop, the cylinder 14 starts, the piston rod on the cylinder 14 extends, the fixing plate 15 descends, and the hose 17 descends with the fixing plate 15 to the designated position. During the dispensing process, pressure is applied to the piston inside the dispensing tube 17, causing the piston to descend and squeeze the glue through the dispensing needle below the dispensing tube 17 to dispense glue onto the filter 5. Simultaneously, the rotary motor 19 drives the rotating blocks 16 to rotate, causing the dispensing tube 17 to rotate with the rotating shaft 7. The dispensing needle applies a ring of glue to the corresponding position on the filter 5. After dispensing is complete, the cylinder 14 is activated, extending the piston rod and raising the dispensing tube 17. The positioning motor 12 then drives the rotating shaft 7 to rotate again, causing the glued filter 5 to move with the screw 8. After the glued filter 5 separates from the screw 8, multiple filters 5 in the next batch arrive at the corresponding dispensing tube 17, repeating the cycle. This device can perform glue dispensing operations on filters 5, and can dispense multiple filters 5 at once, greatly improving the dispensing efficiency of the filters 5.

[0021] Limiting rods 4 are symmetrically arranged on both sides above the feeding conveyor belt 2. The limiting rods 4 ensure that the filter 5 accurately enters between the two screws 8 and prevent the filter 5 from falling off the feeding conveyor belt 2.

[0022] Among them, the end of the rotating shaft 7 is fixed with a slave pulley 9, and the output end of the positioning motor 12 is fixed with a main pulley 10. The main pulley 10 is connected to the corresponding slave pulley 9 through the synchronous belt 11.

[0023] Each rotating block 16 is fixed with a driven gear 18, and adjacent driven gears 18 mesh with each other. The output end of the rotary motor 19 is fixed with a main gear 20, which meshes with one of the driven gears 18.

[0024] Example 2:

[0025] This embodiment discloses a dispensing device for filter processing. Based on the structure and principle of Embodiment 1, this embodiment further includes a receiving conveyor belt 21 above the bottom plate 1 at the end of the support plate 6. The receiving conveyor belt 21 is driven to rotate by a receiving motor 22. The filter 5 after dispensing reaches the position of the receiving conveyor belt 21 and is collected as the receiving conveyor belt 21 rotates.

[0026] The above are merely preferred embodiments of the present invention. It should be noted that, for those skilled in the art, various changes, modifications, substitutions and variations can be made to these embodiments without departing from the technical principles of the present invention. These changes, modifications, substitutions and variations should also be considered within the scope of protection of the present invention.
