Description

Technical Field

[0001] This invention relates to the field of pump equipment technology, specifically to a glue supply pump for a glue delivery system. Background Technology

[0002] During glue application, the pump body usually provides power to squeeze out the glue. The pressure plate pump is a commonly used glue supply pump. The core working principle of the glue supply pressure plate pump is to use a liftable pressure plate to directly press on the surface of the glue in the glue bucket. Through the pressure of the pressure plate, the glue is continuously pumped out of the bucket and pushed into the glue delivery pipeline, and then delivered to the glue application equipment. It is widely used in the processing and manufacturing industry.

[0003] The invention patent application with publication number CN114320803A discloses a low-pressure pressure plate pump, and the utility model patent with publication number CN216842171U discloses a pressure plate pump with a passive pressure relief structure. Both of them use the pressure of the plate to squeeze out the adhesive. During the pressing process, the adhesive near the plate is squeezed out first, while the adhesive near the bottom of the glue cylinder remains in the glue cylinder for a long time. Under pressure for a long time, internal stress will be generated inside the adhesive. This internal stress will be released after curing, which will cause the product to warp and deform, affecting the quality of the adhesive near the bottom of the cylinder and ultimately affecting the use effect.

[0043] The moving assembly includes a transmission belt 21, multiple pulleys 22, and two connecting pieces 23. The transmission belt 21 is vertically arranged and is sealed and rotatably embedded inside the main shaft 3.

[0045] The disturbance mechanism includes two sets of stirring components and linkage components. The stirring components include a horizontal shaft 26, multiple pairs of blades 27 and a first gear 28. The inner end of the horizontal shaft 26 is horizontally rotatably sleeved in the middle of the main shaft 3. Multiple pairs of blades 27 are evenly and horizontally arranged on the outer surface of the horizontal shaft 26. Each pair of blades 27 is centrally symmetrically arranged. Multiple slots 261 corresponding to the blades 27 are opened on the outer side of the horizontal shaft 26. Both shaft ends of the blades 27 are rotatably sleeved in the slots 261, and each shaft end is fitted with a first torsion spring 29. The first gear 28 is fixedly sleeved on the inner end of the horizontal shaft 26.

[0046] On the side of the two pressure plates 2 that are close to each other, there are multiple sets of grooves 201 in a ring shape. Each set of grooves 201 is evenly distributed along the radial direction. A guide block 30 is rotatably installed in the groove 201. A second torsion spring 31 is embedded in the shaft end of the guide block 30.

[0047] Each of the two pressure plates 2 has a mounting groove 202 on its side that is close to each other. The mounting groove 202 is semi-cylindrical. When the blade 27 is deflected into the slot 261, the blade 27 and the horizontal shaft 26 are completely attached to each other, forming a smooth horizontal cylinder. When the two pressure plates 2 are attached, the two horizontal shafts 26 are respectively embedded in the upper and lower opposite mounting grooves 202 and are sealed and embedded. The pressure plates 2 have corresponding insertion holes 203 at the positions where the first telescopic tube 11 and the second telescopic tube 18 are installed. When the two pressure plates 2 are attached, the first telescopic tube 11 and the second telescopic tube 18 are in a retracted state and are completely inserted into the insertion holes 203. When the guide block 30 is deflected into the groove 201, it is sealed and attached to the groove 201 and is flush with the surface of the pressure plate 2.

[0048] The rotating assembly includes a motor 32, a transmission shaft 33, a support plate 34, and four connecting rods 35. The motor 32 is vertically arranged and its top end is connected to the lifting mechanism. The support plate 34 is horizontally arranged. The top end of the main shaft 3 passes through the middle of the support plate 34 and is rotatably sleeved inside the support plate 34. The four connecting rods 35 are symmetrically arranged vertically, and their upper and lower ends are fixedly connected to the bottom side of the motor 32 and the support plate 34, respectively. The top ends of multiple first cylinders 25 are all fixedly connected to the bottom surface of the support plate 34.

[0049] The upper side of the motor 32 is fixedly connected to the bottom of the two uprights 42.

[0050] The linkage assembly includes a rotating shaft 36, a second gear 37, a third gear 38, and a gear ring 39. The gear ring 39 is horizontally fixed on the upper side of the support plate 34. The rotating shaft 36 is vertically rotatably installed inside the main shaft 3 and is offset from the center of the main shaft 3. The second gear 37 is fixedly installed on the top of the rotating shaft 36 and meshes with the gear ring 39. The third gear 38 is fixedly installed on the bottom of the rotating shaft 36 and meshes with the two first gears 28.

[0051] When using this device to transport adhesive, the initial position is that the second cylinder 40 is extended to its upper limit. The trolley carrying the adhesive bucket is pushed to the middle of the base 1, and the brake pedal is pressed to fix the trolley. The adhesive bucket is locked on the upper side of the trolley and faces the pressure plate 2. At this time, the two pressure plates 2 are in a separated state.

[0052] After the glue bucket is aligned, the second cylinder 40 is activated. The second cylinder 40 shortens, driving the motor 32 to descend via the truss 41 and the upright 42. The motor 32, through the connecting rod 35, drives the support plate 34 to move downwards. The support plate 34 drives the main shaft 3 to move downwards. The main shaft 3 drives the two pressure plates 2 to slowly move downwards. At this time, the bladder 14 is in a contracted state. When the pressure plate 2 on the bottom side comes into contact with the glue, it squeezes the glue. Under the pressure, the glue overflows upwards from the space between the inner wall of the glue bucket and the outside of the bladder 14 until the bottom surface of the pressure plate 2 touches the bottom wall of the glue bucket. Upon contact, the second cylinder 40 stops operating, and then the pump body device 44 starts, introducing filling liquid into the delivery pipe 43 through the hose 45. The filling liquid flows into the annular groove 15 sequentially through the second guide cavity 16, the second drainage pipe 20, the second telescopic pipe 18, and the connecting pipe 19, and finally flows into the bladder 14 through the port, causing the bladder 14 to expand. Finally, the bladder 14 expands and fits tightly against the inner wall of the glue bucket, forming a closed space between the two pressure plates 2 and sealing the glue liquid between the two pressure plates 2. The main shaft 3 contacts the bottom of the glue bucket, but exerts no pressure on the glue bucket.

[0053] Then, the glue supply operation is carried out. The first cylinder 25 extends and drives the upper pressure plate 2 to move down through the chuck 24. The upper pressure plate 2 moves down and drives the transmission belt 21 to rotate under the support of multiple pulleys 22 through the connector 23. The upper pressure plate 2 is connected to the side of the transmission belt 21 that moves down, and the lower pressure plate 2 is connected to the side of the transmission belt 21 that moves up, so that the lower pressure plate 2 moves up. The two pressure plates 2 move closer to each other and squeeze the glue. First, the air on the top layer of the glue is discharged. As the pressure is increased, the glue is compressed and pressed into the horizontal tube 5 through the suction head 6 embedded in the two pressure plates 2. Then it enters the ring tube 4 through the horizontal tube 5, then enters the first telescopic tube 11 through the ring tube 4, then enters the first drainage tube 12 through the first telescopic tube 11, then enters the first guide cavity 7, and finally is output through the glue tube 10 and sent into the glue coating equipment for glue coating operation.

[0054] With the cooperation of the two pressure plates 2, the adhesive can be squeezed out from both the top and bottom of the adhesive layer at the same time, which can effectively prevent one end of the adhesive layer from being under pressure for a long time, thus ensuring that the adhesive has good quality.

[0055] During the extrusion process, the motor 32 operates, driving the main shaft 3 to rotate via the transmission shaft 33. The main shaft 3 then drives the two horizontal shafts 26 and the two pressure plates 2 to rotate.

[0056] The two pressure plates 2 rotate, causing the guide blocks 30 inside them to rotate, guiding the adhesive liquid and making it flow up and down. The horizontal shaft 26 rotates, causing the multiple blades 27 located on it to rotate, stirring and agitating the adhesive liquid in the middle, promoting flow.

[0057] Driven by the rotating components, the guide block 30, the blade 27 and the horizontal shaft 26 rotate, causing the adhesive to flow between the two pressure plates 2, thereby allowing the adhesive from different areas to be discharged alternately, further preventing the adhesive in local areas from being under pressure for a long time.

[0058] The rotation of the main shaft 3 drives the horizontal shaft 26 to rotate, and at the same time drives the rotating shaft 36 to revolve. The rotating shaft 36 drives the second gear 37 to revolve, which meshes with the gear ring 39, thereby causing the rotating shaft 36 to rotate on its own axis while revolving. The rotation of the rotating shaft 36 drives the third gear 38 at the bottom to rotate. The rotation of the third gear 38 drives the two first gears 28 to rotate. The two first gears 28 drive the two horizontal shafts 26 to rotate respectively, so that the horizontal shaft 26 drives the blade 27 to revolve on its own axis while revolving, which can further agitate the adhesive in the vertical direction, so that the adhesive can flow fully.

[0059] Under the squeezing action of the two pressure plates 2, combined with the disturbance action, the original air bubbles inside the adhesive can be broken, which facilitates the discharge of gas inside the adhesive, making the adhesive more compact and further improving the quality of the adhesive. The discharged gas is discharged through the exhaust valve in the adhesive coating equipment connected to the adhesive tube 10.

[0060] As the two pressure plates 2 continuously move and compress, all the adhesive is squeezed out. Finally, the two pressure plates 2 come together, and the guide block 30 is deflected into the groove 201 under pressure. The second torsion spring 31 generates torque. Similarly, the blade 27 is deflected under pressure and embedded into the corresponding slot 261. The first torsion spring 29 generates torque. When the two pressure plates 2 separate and reset, the first torsion spring 29 and the second torsion spring 31 release their torque, causing the guide block 30 and the blade 27 to reset. The triggering torque of the first torsion spring 29 and the second torsion spring 31 is greater than the pressure of the adhesive, thereby ensuring that the guide block 30 and the blade 27 remain in an unfolded state during the adhesive extrusion process to guide the adhesive.
