Description

Technical Field

[0001] This invention relates to the field of adhesive spraying track technology, specifically to a dual-track synchronous mobile device for adhesive spraying. Background Technology

[0002] Spray adhesives are adhesives that achieve bonding through a spraying process. This refers to both the spraying technique and the adhesive product itself. They are mainly used for bonding materials such as sofa foam, fabric, and leather, and are characterized by strong initial tack, high efficiency, and repeatable positioning. Traditional spray adhesives contain benzene-based solvents, while environmentally friendly water-based spray adhesives use non-toxic raw materials and possess low odor, fast drying, and temperature and water resistance, making them widely used in the furniture, bag, and decoration industries.

[0003] A search revealed Chinese patent CN103100502A, which discloses a glue-spraying actuator for a glue-spraying laminating machine that ensures uniform glue spraying. The actuator includes: a frame; a variable frequency motor mounted on the frame, connected to a drive wheel; the drive wheel connected to a driven wheel via a transmission chain; a track on the frame; a guide frame slidably mounted on the track via rollers; the guide frame connected to a conveyor chain; a spray gun mounting bracket connected to the guide frame; several spray gun mounting holes on the spray gun mounting bracket; a spray gun mounted on the spray gun mounting bracket via screws; and a feed pipe connected to the spray gun. This glue-spraying actuator of the aforementioned glue-spraying laminating machine provides uniform glue spraying, and the angle is adjustable, meeting usage requirements.

[0004] Existing dual-track synchronous mobile devices for glue spraying have the problem that the glue spraying mechanism cannot move stably and at a constant speed when moving along the track at corner positions, and the glue spraying mechanism cannot stay in the center position when the dual tracks move at corner positions. To address these issues, a dual-track synchronous mobile device for glue spraying is proposed. Summary of the Invention

[0007] Preferably, the dragging assembly includes a first dragging plate, the lower surfaces of both ends of the first dragging plate are fixedly connected to the dragging base, a tension spring is fixedly connected to the first dragging plate, the end of the tension spring away from the first dragging plate is fixedly connected to the first dragging plate, and a second dragging plate is slidably connected to the dragging base.

[0008] Preferably, the correction mechanism includes a positioning correction plate, which is fixedly connected to a first drag plate. The positioning correction plate has an arc-shaped groove on its surface and teeth on one side of the arc-shaped groove. The correction mechanism also includes a movable correction plate, which is fixedly connected to a second drag plate. The movable correction plate has teeth on its surface. A protective shell is fixedly connected to the surface of the positioning correction plate. The correction mechanism also includes a misalignment pin, the lower end of which is fixedly connected to a glue spraying mechanism.

[0009] Preferably, the misalignment pin includes a connecting shaft, which is fixedly connected to the glue spraying mechanism. A misalignment gear is rotatably connected to the upper end of the connecting shaft. The misalignment gear is meshed with both the positioning and straightening plate and the movable straightening plate. A reinforcing plate is fixedly connected to the upper end of the misalignment gear.

[0010] Preferably, the stabilizing shell is U-shaped in general. The stabilizing shell includes a wrapping shell, a stabilizing groove is provided on the inner side of the wrapping shell, and a traveling groove is also provided on the inner side of the wrapping shell. The sidewall of the traveling groove is provided with teeth.

[0011] Preferably, the stabilizing plate assembly includes a clamping plate that slides inside the stabilizing groove, the clamping plate engages with a second drag plate, and a traveling gear is rotatably connected to the surface of the clamping plate, the traveling gear meshing with the teeth inside the traveling groove.

[0012] Preferably, the winding mechanism has winding shafts at both ends, with the traction line wound and fixedly connected to the surface of the winding shaft. The two sets of winding shafts are fixedly connected to the side of each other via a connecting shaft, and the teeth on the surfaces of the two sets of linkage gears mesh with each other. The winding mechanism is rotatably connected to the positioning shell. There are two sets of winding mechanisms, and the two sets of winding mechanisms are respectively connected to the two sets of traction lines.

[0013] Preferably, the positioning chain consists of several sets of sliding blocks, which slide in the grooves inside the track shaft, are fixed to the surface of the traction line, and can be bent between each other.

[0014] Preferably, the limiting ring is circular in shape and is sleeved on the outside of the track shaft. The lower end of the limiting ring is fixedly connected to the lower end of the positioning chain, and the upper end of the limiting ring is fixedly connected to the drag base.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This glue spraying device uses a dual-track synchronous mobile device. By setting two sets of track shafts and traction lines on the inner side, and controlling the winding and unwinding of the traction lines through two sets of independent winding mechanisms, the traction lines of the two track shafts will not always move at the same speed. This allows the traction line with a larger diameter to wind up faster than the traction line with a smaller diameter at corners. This ensures that the glue spraying mechanism can always maintain the centerline position when moving along the dual tracks, achieving the effect of stable movement of the glue spraying mechanism along the track shaft path. This solves the problem of the glue spraying mechanism being unable to move stably at corners when moving along the track.

[0016] 2. This dual-track synchronous mobile device for adhesive spraying uses a dragging assembly above the dragging base to allow the first and second dragging plates to push and pull each other. A stabilizing plate assembly controls the angle of the second dragging plate, ensuring it remains perpendicular to the track axis. A correction mechanism is installed outside the dragging assembly, allowing the positioning and movable correction plates to be pulled open during cornering. This allows the misalignment pins inside the correction mechanism to be rubbed, keeping them centered within the correction mechanism. This makes the adhesive spraying mechanism more stable as it moves along the track axis, solving the problem of the adhesive spraying mechanism failing to maintain its centered position during dual-track cornering.

[0017] 3. This adhesive spraying device uses a dual-track synchronous mobile unit. By setting a stabilizing plate assembly to move inside the stabilizing shell, the clamping disc can slide inside the stabilizing groove. By setting a traveling gear to rotate inside the traveling groove, the stabilizing plate assembly can control the second drag plate to be in a state perpendicular to the track axis. The rotation of the traveling gear prevents the clamping disc from slipping and losing speed when sliding along the corner of the stabilizing groove, thus achieving the effect of controlling the adhesive spraying mechanism to move at a constant speed at the corner and solving the problem of the adhesive spraying mechanism losing speed at the corner.

[0024] like Figure 1-8 As shown, a dual-track synchronous mobile device for spraying adhesive includes a positioning shell 1. A track shaft 2 is fixedly connected to the surface of the positioning shell 1. A traction line 3 is provided inside the track shaft 2. A winding mechanism 4 is provided inside the positioning shell 1. The traction line 3 is fixedly connected to and wound around the outside of the winding mechanism 4. The winding mechanism 4 has winding shafts 41 at both ends. The traction line 3 is wound around and fixedly connected to the surface of the winding shafts 41. The two sets of winding shafts 41 are fixedly connected to the side of each other via a connecting shaft, and the teeth on the surfaces of the two sets of linkage gears 42 mesh with each other. The winding mechanism 4 is rotatably connected to the positioning shell 1. The winding mechanism 4 is provided with a total of Two sets of winding mechanisms 4 are connected to two sets of traction lines 3 respectively. The winding mechanisms 4 are configured to be connected to two different traction lines 3 respectively. The winding mechanisms 4 drive the winding shafts 41 on both sides through the meshing of two sets of linkage gears 42, so that the winding shafts 41 can wind and unwind the line when rotating, achieving the effect of pulling the traction line 3. By controlling the winding and unwinding of the traction line 3 through two sets of independent winding mechanisms 4, the traction lines 3 of the two sets of track shafts 2 will not always move at the same speed. This allows the winding speed of the traction line 3 with a larger diameter to be faster than that of the traction line 3 with a smaller diameter at the corner.

[0025] The track shaft 2 has two sets of tracks: an inner first track 21 and an outer second track 22. Positioning chains 23 are slidably connected to the inner sides of both the first track shaft 21 and the second track shaft 22. The positioning chains 23 are fixedly connected to the traction line 3. The positioning chains 23 are composed of several sets of sliding blocks. The sliding blocks slide in the grooves on the inner side of the track shaft 2 and are fixed to the surface of the traction line 3. The sliding blocks can be bent. By setting an array of sliding blocks, the positioning chains 23 can be bent at the corner positions of the track shaft 2 to prevent the positioning chains 23 from getting stuck on the inner side of the bend of the track shaft 2.

[0026] A limiting ring 5 is fixedly connected to the outside of the positioning chain 23. Two sets of limiting rings 5 ​​are respectively sleeved on the outside of the first track 21 and the second track 22. A drag base 6 is fixedly connected to the upper end of the positioning chain 23. The limiting ring 5 is circular in shape and is sleeved on the outside of the track shaft 2. The lower end of the limiting ring 5 is fixedly connected to the lower end of the positioning chain 23, and the upper end of the limiting ring 5 is fixedly connected to the drag base 6. The limiting ring 5 can be sleeved on the outside of the track shaft 2, so that the positioning chain 23 can slide inside the track shaft 2 by being restricted by the limiting ring 5.

[0027] A towing assembly 7 is fixedly connected to the upper end of the towing base 6. The towing assembly 7 includes a first towing plate 71. The lower surfaces of both ends of the first towing plate 71 are fixedly connected to the towing base 6. A tension spring 72 is fixedly connected to the first towing plate 71. A second towing plate 73 is fixedly connected to the end of the tension spring 72 away from the first towing plate 71. The second towing plate 73 is slidably connected to the towing base 6. The towing assembly 7 connects the first towing plate 71 and the second towing plate 73 through the tension spring 72, so that the first towing plate 71 can push the second towing plate 73 forward when it is in a straight position. When turning, the second towing plate 73 can use the tension spring 72 to pull the end of the first towing plate 71 away from the center of the turning circle to move, so that the first towing plate 71 and the second towing plate 73 can turn more stably.

[0028] The surface of the dragging component 7 is snapped with a stabilizing plate component 8, and the surface of the positioning shell 1 is fixedly connected with a stabilizing shell 9. The stabilizing shell 9 is U-shaped and includes a wrapping shell 91. A stabilizing groove 92 is provided on the inner side of the wrapping shell 91, and a traveling groove 93 is also provided on the inner side of the wrapping shell 91. The side wall of the traveling groove 93 is provided with teeth. By setting the wrapping shell 91, the stabilizing plate component 8 can slide along the stabilizing groove 92. By setting the traveling groove 93, the stabilizing plate component 8 will not slip at the corner position, resulting in directional misalignment or loss of movement speed.

[0029] The stabilizing plate assembly 8 includes a clamping disc 81, which slides inside the stabilizing groove 92. The clamping disc 81 is engaged with the second drag plate 73. A traveling gear 82 is rotatably connected to the surface of the clamping disc 81. The traveling gear 82 meshes with the teeth inside the traveling groove 93. By setting the clamping disc 81 to move inside the stabilizing groove 92, the stabilizing plate assembly 8 can move along a predetermined moving trajectory of the stabilizing groove 92. By setting the rotatable traveling gear 82, the stabilizing plate assembly 8 will not slip or remain stationary when moving to a corner.

[0030] A correction mechanism 10 is provided on the surface of the drag assembly 7. A glue spraying mechanism 11 is fixedly connected to the lower end of the correction mechanism 10. The correction mechanism 10 includes a positioning correction plate 101, which is fixedly connected to the first drag plate 71. The surface of the positioning correction plate 101 is provided with an arc-shaped groove, and teeth are provided on one side of the arc-shaped groove. The correction mechanism 10 also includes a movable correction plate 102, which is fixedly connected to the second drag plate 73. The surface of the movable correction plate 102 is provided with teeth. A protective shell 103 is fixedly connected to the surface of the positioning correction plate 101. Mechanism 10 also includes a misalignment pin 104, the lower end of which is fixedly connected to the glue spraying mechanism 11. The correction mechanism 10 is fixed to the surface of the first drag plate 71 by setting a positioning correction plate 101 and a movable correction plate 102 fixed to the surface of the second drag plate 73. The position of the misalignment pin 104 is changed by the rubbing motion of the positioning correction plate 101 and the movable correction plate 102 during movement, so that the misalignment pin 104 can always be in the center position of the correction mechanism 10 when the correction mechanism 10 turns, making the rotation of the misalignment pin 104 more stable and uniform.

[0031] The misaligned pin 104 includes a connecting shaft, which is fixedly connected to the glue spraying mechanism 11. A misaligned gear 1041 is rotatably connected to the upper end of the connecting shaft. The misaligned gear 1041 is meshed with both the positioning and straightening plate 101 and the movable straightening plate 102. A reinforcing plate 1042 is fixedly connected to the upper end of the misaligned gear 1041. By setting a rotatable misaligned gear 1041 at the upper end of the misaligned pin 104, the straightening mechanism 10 can rub the misaligned pin 104 when it deforms at an angle, so that the position of the misaligned pin 104 can change with the deformation. This makes the glue spraying mechanism 11 driven by the misaligned pin 104 more stable and smooth when turning at an angle, reducing the problem of uneven speed when turning at an angle.

[0032] In use, the positioning shell 1 is installed on top, so that the track shaft 2 passes over the glue spraying area. When it is necessary to move the glue spraying mechanism 11, the motor is started to drive the linkage gear column 42 to rotate. Driven by the linkage gear column 42, the take-up shafts 41 at both ends rotate synchronously. The take-up shafts 41 at both ends rotate in different directions driven by the linkage gear column 42. The take-up shaft 41 at one end rotates to wind up the traction line 3, while the take-up shaft 41 at the other end rotates to release the wound traction line 3. At the same time, another set of take-up mechanisms 4 rotates accordingly, so that the positioning chain 23 is aligned with the first track 21. Simultaneously, the inner side of the second track 22 moves, causing the positioning chain 23 to move along the track axis 2 via the limiting ring 5. This causes the drag base 6 to drive the drag assembly 7. The first drag plate 71 pushes the second drag plate 73 to move along the straight section of the track axis 2 via the tension spring 72. The second drag plate 73 drives the stabilizing plate assembly 8 to slide inside the stabilizing shell 9, thereby causing the correction mechanism 10 to follow the drag assembly 7 and move along the straight section of the track axis 2. This allows the glue spraying mechanism 11 to reach a suitable position on the outer side of the track axis 2. When it reaches the corner position, since the first track 21 is within the inner circle corner diameter... Because the traction line 3 is relatively small, when the traction line 3 turns, the inner side of the first track 21 first drives the positioning chain 23, causing the first drag plate 71 to push the second drag plate 73 through the tension spring 72. The second drag plate 73 then drives the clamping plate 81 to slide smoothly inside the stabilizing groove 92. Through the meshing rotation of the travel gear 82 inside the travel groove 93, the second drag plate 73 rotates along the bending arc of the travel groove 93. The clamping plate 81 controls the second drag plate 73, ensuring that the second drag plate 73 remains perpendicular to the first track 21 when the first track 21 turns. After the second drag plate 73 rotates, the end near the first track 21 is pushed by the tension spring 72, and the end away from the first track 21 is driven by the tension spring 72 to drive the first drag plate 71 to pass through the corner. The second drag plate 73 forms an angle with the first drag plate 71, and the second drag plate 73 drives the movable correction plate 102 to move. Through the meshing of the misalignment pin 104, the misalignment pin 104 is always between the positioning correction plate 101 and the movable correction plate 102, so that the glue spraying mechanism 11 can still be in a relatively stable rotational state at the corner position.
