Description

Technical Field

[0001] The utility model relates to the field of automatic glue injection devices for filter element end caps, and particularly relates to an automatic glue injection device for filter element end caps. Background Technique

[0002] The filter element end cap mainly plays the roles of sealing both ends of the filter material and supporting the filter material. It is mainly made of steel plates stamped into various shapes according to needs. When the filter element is in use, the air filter needs to bear a large stress, and the end cap can effectively improve the bearing capacity of the filter material. Generally, one side of the end cap is stamped into a groove that can place the end face of the filter material and hold the adhesive. During production, a glue injection device is required to first inject an appropriate amount of adhesive into the groove of the end cap that holds the adhesive, so as to facilitate subsequent bonding connection.

[0003] As disclosed in the utility model with the authorization announcement number CN220444265U, an automatic glue injection device for filter element end caps includes a glue injection table. A bracket is fixedly connected to the upper surface of the glue injection table. A glue injection tank is fixedly installed on the inner wall of the bracket. The lower surface of the glue injection tank is fixedly communicated with glue injection pipes distributed in a linear array. Symmetrically distributed guide rods are fixedly connected to the upper surface of the glue injection table. In this utility model, through the settings of the rotating rod, support block, driven gear, servo motor, rotating shaft, and driving gear, after the end caps to be injected with glue are sequentially placed in the placement grooves, the mounting block is picked up by the handle and inserted through the guidance of the guide rods. At this time, one end of the rotating rod passes through the through groove through the support block and jacks up the lower end of the end cap, so that the end cap is separated from the bottom of the placement groove. At this time, the upper part of the end cap is injected with glue through multiple glue injection pipes. At the same time, the servo motor is started to drive the rotating shaft to rotate one circle. The rotation of the rotating shaft drives the driving gear to rotate. The rotation of the driving gear drives the driven gear to rotate. Since the multiple driven gears are meshed with each other, the multiple rotating rods rotate. The rotation of the rotating rod 64 drives the end cap to rotate through the support block, so as to cooperate with the glue injection pipes to achieve uniform rotational glue injection. When the device injects glue, only the bottom surface of the end cap contacts the upper surface of the support block, and the end cap is unstable. It is very likely that during glue injection, affected by the glue, the rotation of the end cap is not smooth, thus affecting the glue injection quality. Content of the Utility Model

[0020] Please refer to Figure 1 - Figure 4As shown in the figure, the utility model provides an automatic glue injection device for the filter element end cover, including a workbench 1, a glue injection tank 7, and a glue injection head 17. A connecting shaft 18 is arranged at the lower end of the placing plate 13, and the lower end of the connecting shaft 18 is embedded in the plate body of the workbench 1 through a bearing, making the connecting shaft 18 and the placing plate 13 more stable. A pulley 19 is arranged on the connecting shaft 18, and the pulleys 19 on two adjacent connecting shafts 18 are linked through a transmission belt 20. There is a pulley 19 on the rightmost connecting shaft 18, and two pulleys 19 are arranged on each of the connecting shafts 18 on the left side. A driving motor 21 is embedded on the left side of the workbench 1, and a pulley 19 is installed on the output shaft of the driving motor 21. The pulley 19 installed on the output shaft of the driving motor 21 is connected to the pulley 19 arranged on the leftmost connecting shaft 18 through a transmission belt 20. Symmetrically arranged telescopic cylinders 4 are installed on the upper surface of the workbench 1, and a supporting bracket 5 is connected to the upper end of the telescopic cylinder 4. Symmetrically arranged clamping grooves 6 are formed on the inner side plate body of the supporting bracket 5. A glue injection tank 7 is arranged on the supporting bracket 5. A complete glue injection structure is arranged in the glue injection tank 7, which can control the glue injection. A clamping block 8 corresponding to the position of the clamping groove 6 is formed on the lower end surface of the glue injection tank 7, and the clamping block 8 can slide back and forth in the clamping groove 6. A glue injection head 17 corresponding to the center position of the placing plate 13 is formed on the lower surface of the glue injection tank 7. A vertical fixing substrate 9 is formed at the rear side of the supporting bracket 5. A threaded rod 10 passes through the plate body of the fixing substrate 9, and the threaded rod 10 is screwed with the fixing substrate 9. The front end of the threaded rod 10 is connected to the glue injection tank 7 through a bearing, and an adjusting wheel 11 is installed at the rear end of the threaded rod 10. Legs 2 are formed at the diagonal positions on the lower surface of the workbench 1;

[0021] After the end cover is placed, rotate the adjusting wheel 11 to drive the threaded rod 10 to rotate. The rotation of the threaded rod 10 and its screwing with the fixing substrate 9 push or pull the clamping block 8 below the glue injection tank 7 to slide back and forth along the clamping groove 6, so that the glue injection tank 7 drives the glue injection head 17 to move until the glue injection head 17 corresponds to the position of the inner groove of the end cover. Then control the telescopic cylinder 4 to contract, driving the supporting bracket 5 to move downward until the glue injection head 17 on the lower surface of the glue injection tank 7 extends into the end cover, and start glue injection. At the same time, start the driving motor 21. The rotation of the driving motor 21 drives the pulley 19 on the output shaft of the driving motor 21 to rotate, and the transmission belt 20 drives, so that each connecting shaft 18 rotates, and the placing plate 13 rotates accordingly;

[0022] As Figure 1 - Figure 4As shown in the figure, an installation frame 3 is formed above the workbench 1. A plurality of installation grooves 12 are opened on the upper plate body of the installation frame 3. A rotatable circular placement plate 13 is clamped inside the installation groove 12. Connecting rods 14 are symmetrically penetrated through the left and right sides of the placement plate 13. The connecting rods 14 penetrate through the placement plate 13 and extend into the interior of the placement plate 13. A top spring 22 is sleeved on the connecting rods 14 inside the placement plate 13. A clamping block 16 is connected to the end of the connecting rod 14. A slope is formed at the top of the inner side of the clamping block 16 to facilitate the insertion of the end cover. The top spring 22 is located between the placement plate 13 and the clamping block 16. Guide rods 15 fixedly connected to the fixed side surface of the placement plate 13 are arranged on the front and rear sides of the connecting rod 14. The guide rods 15 penetrate through the placement plate 13. The arrangement of the guide rods 15 can limit the position of the clamping block 16 and prevent it from rotating;

[0023] When fixing the end cover, place the end cover between the two clamping blocks 16 and gently press down. The end cover slides down along the slope at the edge of the clamping block 16 and is clamped between the two clamping blocks 16. During this process, the two clamping blocks 16 move away from each other, and the connecting rods 14 and the guide rods 15 move accordingly. The top spring 22 contracts and provides a reaction force to the clamping block 16 to facilitate the clamping of the end cover;

[0024] Specific working principle:

[0025] When using this device, place the end cover between the two clamping blocks 16 and gently press down. The end cover slides down along the slope at the edge of the clamping block 16 and is clamped between the two clamping blocks 16. Rotate the adjusting wheel 11 to drive the threaded rod 10 to rotate. The rotation of the threaded rod 10 engages with the fixed base plate 9 to push or pull the block 8 below the glue injection box 7 to slide back and forth along the card slot 6, so that the glue injection box 7 drives the glue injection head 17 to move until the glue injection head 17 corresponds to the position of the inner groove of the end cover. Then control the telescopic cylinder 4 to contract, driving the support bracket 5 to move downward until the glue injection head 17 on the lower surface of the glue injection box 7 extends into the end cover, and start glue injection. At the same time, start the driving motor 21. The rotation of the driving motor 21 drives the pulley 19 on the output shaft of the driving motor 21 to rotate, and the transmission belt 20 drives, so that each connecting shaft 18 rotates, the placement plate 13 rotates accordingly, and the end cover rotates to complete the glue injection.
