Description

Technical Field

[0001] This utility model belongs to the field of plastic bottle cap packaging technology, and specifically relates to a plastic bottle cap packaging machine. Background Technology

[0002] In the packaging of high-value-added products such as cosmetics and pharmaceuticals, plastic bottle caps are an important packaging component, and the accuracy of their final packaging quantity is crucial. Shortages can lead to customer complaints, reputational damage, and legal risks, while overproduction can result in unnecessary increases in production costs.

[0003] Existing plastic bottle cap packaging machines mainly use photoelectric counting or weighing counting methods. Photoelectric counting devices count the number of times the bottle cap blocks the light when it passes through the optical sensor. Although this method is fast, it has obvious drawbacks: First, when bottle caps overlap or are closely connected, the sensor is very likely to misidentify them as a single bottle cap, resulting in a reduced count. Second, for transparent, light-colored, or highly reflective bottle caps, the light blocking is not obvious or diffuse reflection occurs, which can easily cause the sensor to malfunction and result in missed counts.

[0004] The weighing and counting method estimates the quantity by measuring the total weight. Its accuracy is highly dependent on the consistency of the weight of each bottle cap. It has extremely high requirements for manufacturing tolerances and raw material stability. The accuracy of the packaging quantity is poor, which affects its use. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figure 1 - Figure 6 As shown, a plastic bottle cap packaging machine includes: a base plate 1, an mounting plate 2 fixedly mounted on the top of the base plate 1 by multiple support rods, a rotating seat 3 rotatably mounted through the mounting plate 2, a rotating component mounted on the rotating seat 3, a turntable 4 fixedly mounted on the top of the rotating seat 3, multiple receiving slots opened on the side of the turntable 4, a set assembly mounted on the turntable 4, a baffle 5 on the outer side of the turntable 4, the baffle 5 being annularly arranged and having a feeding port, a feeding component mounted at the feeding port, and a counting mechanism mounted on the turntable 4;

[0027] The counting mechanism includes a mounting frame 6 set above the feed inlet. The mounting frame 6 is fixedly set on the top of the baffle 5. A capacitive sensor 7 is fixedly set at the bottom of the mounting frame 6. A first feed port is opened on the mounting plate 2 and a second feed port is opened on the bottom plate 1. A feed pipe 8 is set between the first feed port and the second feed port. Two symmetrically arranged mounting frames 9 are fixedly set through the feed pipe 8. Photoelectric sensor components 10 are set inside the two mounting frames 9.

[0028] The photoelectric sensor assembly 10 includes a photoelectric generator and a photoelectric receiver, which are respectively disposed on the inner sidewalls of two mounting frames 9 and aligned with each other.

[0029] As can be seen from the above, the capacitive sensor 7, which is fixed to the top of the baffle 5 by the mounting bracket 6, can perform the initial detection and counting of bottle caps entering the receiving slot on the turntable 4 from the feed port. It utilizes the difference in dielectric constant between the bottle cap and air to achieve non-contact sensing, effectively avoiding the problem of traditional optical sensors failing to detect transparent and reflective bottle caps.

[0030] When the turntable 4 rotates to the first feeding port position with the bottle cap, the bottle cap falls and passes through the feeding tube 8. The photoelectric sensor assembly 10, which is installed in the mounting frame 9, consists of a photoelectric generator and a photoelectric receiver that are aligned with each other. It will perform secondary detection on the falling bottle cap and form a dual signal verification mechanism. This design greatly improves the reliability of the counting process and ensures that every bottle cap that falls into the packaging bag is accurately recorded, thereby achieving high-precision and high-reliability packaging of high-priced bottle caps.

[0031] The material (plastic bottle caps) arranged in an orderly manner is conveyed to the conveying track 19 by a vibratory feeder (not shown in the figure, but it is a common standard configuration in the industry). After being counted, the material falls into the bag maker (not shown in the figure) of the vertical bag packaging machine connected to it through the second discharge port to complete the bagging.

[0032] When turntable 4 rotates, a receiving slot on it passes through the feed port and successfully receives a bottle cap. The bottle cap will immediately enter the detection area of ​​the capacitive sensor 7 directly above it. The capacitive sensor 7 generates an electrical signal change by detecting the difference in dielectric constant between the bottle cap (medium) and air, and sends a pulse signal to the control system, indicating that "a bottle cap has been detected and is in place". The control system records this as a predicted number.

[0033] When the turntable 4, carrying the counted bottle caps, rotates to the first discharge port position above the discharge pipe 8, the bottle caps fall due to gravity. During the fall, the bottle caps will momentarily block the light path of the through-beam photoelectric sensor assembly 10 (composed of a photoelectric generator and a photoelectric receiver). The photoelectric sensor assembly 10 detects this blockage and immediately sends another pulse signal to the control system, indicating that "one bottle cap has been confirmed to have fallen". The control system is a programmable logic controller (PLC), which is not shown in the figure.

[0034] Within the preset time sequence, the PLC will determine that this is a valid count only after receiving both the capacitance signal and the photoelectric signal, and will increase the final count. If there is only a capacitance signal but no photoelectric signal (indicating that the bottle cap did not fall properly), or only a photoelectric signal but no capacitance signal (indicating that a foreign object has fallen or the capacitance sensor 7 has failed to detect), the PLC will determine that it is abnormal, and then stop the machine to end the counting and packaging work, so as to facilitate maintenance and recounting and packaging, and ensure the accuracy of the packaging quantity.

[0035] Specifically, regarding the aforementioned rotating assembly, the rotating assembly includes a sealed box fixedly installed at the bottom of the mounting plate 2, a motor 11 fixedly installed at the top of the base plate 1, an output shaft 12 fixedly installed at the output end of the motor 11, and bevel gears 13 fixedly installed at both the end of the output shaft 12 and the end of the rotating seat 3, with the two bevel gears 13 meshing with each other.

[0036] As can be seen from the above, after the motor 11 starts, it drives the output shaft 12 to rotate. The power transmission direction is changed through a pair of meshing bevel gears 13, which ultimately drives the rotating seat 3 and the turntable 4 fixed on it to rotate smoothly. This transmission method has a compact structure, transmits large torque, and runs smoothly. The sealed housing can effectively prevent dust from entering the gear meshing area, ensuring the durability and reliable operation of the transmission components, and providing stable power for the intermittent or continuous rotation of the turntable 4.

[0037] Example 2:

[0038] Specifically, regarding the aforementioned kit components, the kit components include a mounting cover 14 that is fitted onto and adapted to the turntable 4, a rubber pad 15 that is fixedly provided on the side of the mounting cover 14, and a connecting component that is directly provided between the mounting cover 14 and the turntable 4.

[0039] The connecting assembly includes a connecting post 16 fixedly mounted on the top of the turntable 4. The outer wall of the mounting cover 14 has a through-hole adapted to the connecting post 16. The top of the connecting post 16 passes through the through-hole and is threadedly connected to a limiting cover 17. A gasket 18 is provided between the limiting cover 17 and the mounting cover 14. The outer wall of the connecting post 16 has an external thread, and the inner wall of the limiting cover 17 has a first threaded groove adapted to the external thread.

[0040] As can be seen from the above, the mounting cover 14 is fastened to the turntable 4 by the connecting component. The rubber pad 15 on its side can effectively prevent the bottle cap from accidentally popping out or being damaged during rotation. At the same time, by setting rubber pads 15 of different thicknesses on the side of the mounting cover 14, the size of the receiving groove can be adjusted, so that the device can be easily adapted to bottle caps of different sizes and improve the applicability of the device.

[0041] The connecting assembly consists of a connecting post 16, a limiting cover 17, and a gasket 18. The mounting cover 14 is pressed and fixed onto the turntable 4 by a threaded connection. The design of this set of components makes it extremely convenient to install and remove the mounting cover 14. Operators can quickly replace the mounting cover 14 with different thickness rubber gaskets 15 according to the size and specifications of the bottle cap, which greatly improves the versatility of the equipment and the efficiency of production changeover.

[0042] Example 3:

[0043] Specifically, regarding the above-mentioned feeding assembly, the feeding assembly includes a feeding track 19 fixedly mounted on the top of the base plate 1 by a bracket. The feeding track 19 is inclined downward and the lowest position is set at the feeding port. Two damping shafts 20 are rotatably mounted near the unloading end of the feeding track 19. Guide plates 21 are fixedly sleeved on the outer walls of the two damping shafts 20.

[0044] A vertically arranged sleeve plate 22 is fixedly installed on the outer wall of the material conveying track 19 near the feeding end. A baffle plate 23 is slidably arranged inside the sleeve plate 22. The baffle plate 23 is located directly above the material conveying track 19. A knob 24 is rotatably arranged on the top of the sleeve plate 22. A screw 25 is fixedly arranged at the bottom of the knob 24. The bottom of the screw 25 passes through the top of the sleeve plate 22 and is threadedly connected to the inner wall of the baffle plate 23. A second threaded groove adapted to the screw 25 is opened on the inner wall of the baffle plate 23.

[0045] As can be seen from the above, the bottle caps slide towards the feed inlet by their own weight via the inclined conveying track 19. The two damping shafts 20 and guide plates 21 at the discharge end can sort and guide the bottle caps to ensure that they enter the receiving groove of the turntable 4 in an orderly manner. By rotating the knob 24 to drive the screw 25 to rotate, the height of the baffle plate 23 in the sleeve plate 22 can be precisely adjusted so that the height between the bottom of the baffle plate 23 and the inside of the conveying track 19 is slightly greater than the height of the bottle cap. This prevents the bottle caps on the conveying track 19 from overlapping and piling up, avoids the piling up of bottle caps from sliding into the receiving groove at the same time, and prevents jamming or counting interference caused by excessive bottle caps entering the receiving groove, thus ensuring the continuity and stability of the feeding process.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
