Description

Technical Field

[0002] In the current packaging process of beverage bottles, the bottle cap tightening mechanism occasionally fails to tighten the bottle cap and the bottle body, resulting in leakage during transportation. Therefore, there is a need in the market for a device that can detect the tightening of bottle caps and tighten the loose bottle caps.

[0003] Chinese patent announcement number CN219015575U discloses a bottle cap production tightening quality inspection machine, including a cross bar and a fixed clamping block, one side of the cross bar is provided with a trachea interface, the side of the lower end face of the cross bar close to the trachea interface is provided with a fixed rod, the side of the slide rail A away from the trachea interface is provided with a slide rail B, and the fixed clamping block is arranged on the side of the lower end face of the cross bar away from the trachea interface. The advantages of this utility model: the installation of the device is convenient by setting the fixed rod and the fixed seat, the fixing of the bottle during the inspection is convenient by setting the cylinder and the clamping block, and the stress change of the bottle body being squeezed can be detected by setting the pressure sensing module, so as to facilitate the detection of the airtightness of the bottle.

[0004] In the prior art, after the bottle is transported to the inspection point by the conveying structure, the bottle body is clamped, and then a twisting force is applied to the bottle cap to detect whether the bottle cap is tightened. The above-mentioned related technology has the following defects: during inspection, since the bottle cap is relatively small in volume relative to the bottle body, the bottle cap is clamped by a plate-like or rod-like structure during clamping, and there are fewer force points on the force circle of the bottle cap, and it is pushed by the power of the mechanical twisting. After the bottle cap and the bottle body are tightened, when the clamping structure continues to apply torque, the torque structure will rotate relative to the bottle cap, which is easy to damage the bottle cap. For this reason, a bottle cap production tightening quality inspection machine is proposed. Summary of the invention

[0016] In summary, the present invention includes the following beneficial technical effects: 1. The present invention provides an inner rod, an outer rod, a winding belt and a pressure telescopic structure. When the bottle cap is clamped, the inner rod is in contact with the outer side of the bottle cap, and the ring plate drives the outer rod to rotate around the bottle cap through the pressure telescopic rod. The inner rod does not rotate first under the damping of the driven plate and the fixed rod, and the outer rod drives the winding belt to gradually wind around the circumferential side of the bottle cap. At the same time, the tightly wound winding belt gradually compresses the pressure telescopic structure. When the pressure telescopic structure reaches the maximum compression, the transmission ring continues to apply torque to the groove ring and the ring plate through the elastic pressure structure and the transmission angle block. The winding belt wrapped around the bottle cap applies torque to different stress points on the circumferential surface of the bottle cap, ensuring that the bottle cap can be evenly subjected to mechanical torque.

[0017] 2. The present invention sets a transmission angle block, an angle groove and a pressure spring. The pressure spring has a tendency to push the transmission angle block to be located in the angle groove. When the transmission ring rotates, the transmission angle block applies torque to the groove ring and the ring plate, and then applies torque to the bottle cap through the winding belt. After the bottle cap is tightened, when the transmission ring continues to rotate, the transmission angle block is pushed to gradually move out of the angle groove and become misplaced, thereby limiting the maximum torque applied to the groove ring and effectively preventing the winding belt from applying excessive torque to the bottle cap and causing damage to the bottle cap.

[0018] 3. The present invention sets an adjusting inner plate, a threaded short rod and a double-headed gear ring. When the double-headed gear ring rotates, it drives the threaded short rod to rotate by meshing with the bevel gear. The adjusting inner plate meshes with the threaded short rod to adjust the initial compression amount of the pressure spring, change the transmission angle block and the angle groove to disengage from the pressure of the pressure spring, thereby controlling the maximum torque output to the groove ring, the ring plate and the winding belt, and adapting to the detection of tightening of different types of bottle caps.

[0019] 4. The present invention provides a threaded inner rod and a bending sleeve. When the adjusting motor drives the threaded inner rod to rotate, the bending sleeve controls the distance between the inner rod and the axis of the driven disk by meshing with the threaded inner rod, thereby controlling the inner rod to contact bottle caps of different diameters.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The following is combined with Figure 1-9 The present invention is described in further detail.

[0023] The embodiment of the present invention discloses a bottle cap production tightening quality inspection machine. Figure 1-9 As shown, it includes a support base 1 and a bottle body clamping mechanism 2. Two bottle body clamping mechanisms 2 are provided. The two bottle body clamping mechanisms 2 are respectively installed on the left and right sides of the support base 1. The bottle body clamping mechanism 2 can control the clamping and fixing of the bottle body. A suspension support structure 5 is installed on the upper surface of the support base 1. A fixing rod 3 is arranged above the support base 1. The upper end of the fixing rod 3 is connected to the upper end of the suspension support structure 5. The suspension support structure 5 includes a suspension frame 51 and two power telescopic rods 52. One end of the power telescopic rod 52 is fixed to the suspension frame 51, and the other end of the power telescopic rod 52 is fixed to the upper surface of the support base 1. The upper end of the fixing rod 3 is fixed to the inner top wall of the suspension frame 51. When the power telescopic rod 52 is extended or retracted, the bottle body and bottle cap of different heights can be detected.

[0024] The lower end of the fixed rod 3 is rotatably sleeved with a driven disk 4, and the damping size between the driven disk 4 and the fixed rod 3 satisfies the following mechanical movement. An inner rod 11 is arranged below the driven disk 4, and an outer rod 12 is arranged on the side of the inner rod 11 away from the axis of the driven disk 4. A winding belt 13 is arranged below the driven disk 4, and the two ends of the winding belt 13 are rotatably sleeved on the outer surfaces of the inner rod 11 and the outer rod 12 respectively.

[0025] A threaded adjustment structure 6 is installed at the upper end of the inner rod 11, and the threaded adjustment structure 6 is installed on the bottom surface of the driven disk 4. The threaded adjustment structure 6 includes a threaded inner rod 61 and a bending sleeve 62. One end of the bending sleeve 62 is threadedly sleeved on the outer surface of the threaded inner rod 61, and one end of the threaded inner rod 61 located outside the bending sleeve 62 is rotatably connected to the bottom surface of the driven disk 4. An adjusting motor 63 is installed on the bottom surface of the driven disk 4, and the output end of the adjusting motor 63 is fixed to the threaded inner rod 61. One end of the bending sleeve 62 away from the threaded inner rod 61 is bent downward and fixed to the upper end of the inner rod 11. When the bending sleeve 62 is engaged with the rotating threaded inner rod 61, the distance between the inner rod 11 and the axis of the fixed rod 3 is controlled, so that the inner rod 11 can contact the circumferential side of the bottle cap with different diameters.

[0026] The outer ring side of the fixed rod 3 is rotatably sleeved with a ring plate 10, and the upper end of the outer rod 12 is installed with a pressure telescopic structure 7, and the other end of the pressure telescopic structure 7 is installed on the bottom surface of the ring plate 10. The pressure telescopic structure 7 includes two elastic telescopic rods 71 ​​and an arc plate 72. The two elastic telescopic rods 71 ​​are bent downward at one end away from the axis of the driven disk 4 and are fixed to the upper surface of the arc plate 72. The other end of the elastic telescopic rod 71 is fixedly installed on the bottom surface of the ring plate 10, and the upper end of the outer rod 12 is fixedly installed in the middle position of the bottom surface of the arc plate 72. The upper end of the elastic telescopic rod 71 is a horizontal end, and the two elastic telescopic rods 71 ​​are fixedly installed at the bottom surface of the ring plate 10. The retractable rods 71 ​​are symmetrically distributed on both sides of the axis of the driven disk 4. The elastic telescopic rods 71 ​​have a tendency to push the arc plate 72 away from the fixed rod 3. When the ring plate 10 drives the outer rod 12 to rotate, the inner rod 11 does not rotate first under the resistance between the driven disk 4 and the fixed rod 3, and the control winding belt 13 is gradually wound around the circumferential side of the bottle cap, gradually pushing the elastic telescopic rod 71 to compress. After the elastic telescopic rod 71 reaches the maximum compression, when the ring plate 10 continues to rotate, when the bottle cap is loose, the inner rod 11 and the outer rod 12 are driven to rotate through the winding belt 13, and the driven disk 4 and the fixed rod 3 are driven to rotate relative to each other.

[0027] A groove ring 14 is coaxially fixed on the upper surface of the ring plate 10, the fixing rod 3 is located on the inner ring side of the groove ring 14, a plurality of angle grooves 15 are provided on the outer ring surface of the groove ring 14, a transmission ring 16 is rotatably sleeved on the outer ring surface of the groove ring 14, a plurality of transmission angle blocks 17 are provided on the inner ring side of the transmission ring 16, and the transmission angle blocks 17 are located inside adjacent angle grooves 15.

[0028] An elastic pressure structure 8 is installed on one side of the transmission angle block 17 away from the groove ring 14, and the other end of the elastic pressure structure 8 penetrates the inner ring surface of the transmission ring 16. The elastic pressure structure 8 includes a bar 81, an outer prism 82 and a pressure spring 83. The pressure spring 83 is located inside the outer prism 82. The transmission ring 16 is fixedly sleeved on the outer surface of the outer prism 82. One end of the outer prism 82 located inside the transmission ring 16 is slidably sleeved on the outer surface of the bar 81. The other end of the bar 81 is fixed to the transmission angle block 17. An adjusting inner plate 821 is slidably inserted inside the outer prism 82. One end of the pressure spring 83 away from the bar 81 is fixed to the adjusting inner plate 821, and the upper end of the adjusting inner plate 821 slides through the outer prism 82. The inner ring surface of the pressure spring 83 has a tendency to push the transmission angle block 17 to engage with the angle groove 15 through the bar 81. The end of the adjusting inner plate 821 located outside the outer prism 82 is threaded with a threaded short rod 822, and the threaded short rod 822 is rotatably connected to the upper surface of the outer prism 82. The adjusting inner plate 821 changes the initial pressure of the pressure spring 83 by engaging with the rotating threaded short rod 822. After the bottle cap is tightened, when the transmission ring 16 continues to rotate, the transmission angle block 17 is pushed to gradually move out of the angle groove 15. The pressure of the pressure spring 83 on the transmission angle block 17 controls the maximum torque received by the groove ring 14. The end of the threaded short rod 822 close to the transmission ring 16 is fixedly sleeved with a bevel gear 823.

[0029] A double-headed gear ring 18 is rotatably sleeved on the outer ring surface of the transmission ring 16, the upper end of the double-headed gear ring 18 is a straight tooth end, and the lower end of the double-headed gear ring 18 is a bevel tooth end. The upper surface of the bevel gear 823 is meshed with the lower bevel tooth end of the double-headed gear ring 18, and a spur gear A20 is meshed on the outer side of the upper straight tooth end of the double-headed gear ring 18. A torsion motor 19 is fixed on the upper surface of the transmission ring 16, and the upper end of the spur gear A20 is fixed to the output end of the torsion motor 19. The torsion motor 19 applies torque to the double-headed gear ring 18 through the spur gear A20, and the bevel gear 823 drives the threaded short rod 822 to rotate by meshing with the double-headed gear ring 18.

[0030] The inner ring surface of one end of the transmission ring 16 located above the groove ring 14 is meshed with a power structure 9, and the power structure 9 is installed on the upper end of the fixed rod 3. The power structure 9 includes a power motor 91 and a spur gear B92. The spur gear B92 is fixed to the output end of the power motor 91, and the power motor 91 is fixed to the fixed rod 3. The spur gear B92 is meshed with the inner ring surface of the upper end of the transmission ring 16, and the power motor 91 applies power to the transmission ring 16 through the spur gear B92.

[0031] The working principle is as follows: after the bottle body is fixed by the bottle body clamping mechanism 2, the inner rod 11 is controlled to contact the outer circumferential side of the bottle cap, the power motor 91 drives the transmission ring 16 to rotate through the spur gear B92, and the pressure spring 83 has a tendency to push the transmission angle block 17 to be located in the angle groove 15. When the transmission ring 16 rotates, the transmission angle block 17 applies a torsional force to the groove ring 14 and the ring plate 10. The inner rod 11 does not rotate first under the damping of the driven disk 4 and the fixed rod 3, and the outer rod 12 drives the winding belt 13 to gradually wind around the circumferential side of the bottle cap, and at the same time the winding belt 13 is tightened. The winding belt 13 gradually compresses the pressure telescopic structure 7. When the pressure telescopic structure 7 reaches the maximum compression, the transmission ring 16 continues to rotate, and the winding belt 13 wrapped around the bottle cap applies torque to different stress points on the circumferential surface of the bottle cap. When the bottle cap is not tightened, the winding belt 13 controls the bottle cap to be tightened to the bottle body. After the bottle cap is tightened, the transmission ring 16 continues to rotate, pushing the transmission angle block 17 to gradually move out of position from the angle groove 15, thereby limiting the maximum torque received by the groove ring 14, and effectively preventing the winding belt 13 from applying excessive torque to the bottle cap and causing damage to the bottle cap.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
