Description

Technical Field

[0001] This utility model relates to the technical field of cap manufacturing, and in particular to equipment for producing composite caps and aluminum-plastic composite caps. Background Technology

[0002] like Figure 1 As shown, this is a custom-made aluminum-plastic composite cap, consisting of an aluminum cap and a hollow plastic cap, assembled together using a non-adhesive method. This aluminum-plastic composite cap is used in non-carbonated beverage bottles. After the beverage undergoes high-temperature sterilization, some of the air inside the bottle expands due to heat and escapes. Upon cooling, the air inside the bottle contracts, creating negative pressure that causes the cap to latch onto the bottle opening. Simultaneously, the safety button in the center of the aluminum cap is pulled down. If the beverage bottle leaks, the safety button will re-erect, allowing the consumer to be notified of any leaks.

[0003] Currently, aluminum-plastic composite covers are assembled manually by workers. Workers first need to align the plastic and aluminum covers correctly, then place the aluminum cover on top of the plastic cover, and finally use a pressure bar to press the aluminum cover into the plastic cover. This assembly process is not only time-consuming and labor-intensive, but also prone to errors due to inconsistent pressure and direction from the workers, easily leading to the aluminum cover not being properly pressed into the plastic cover, resulting in defective products. Utility Model Content

[0004] The present invention aims to provide a composite cap production equipment to automatically produce qualified aluminum-plastic composite caps.

[0005] According to a first aspect of the present invention, a combined cap production apparatus includes:

[0006] The combined device includes a frame, a rotating shaft, a lower turntable, an upper turntable, a positioning turntable, and multiple pressing rods. The rotating shaft is arranged vertically and rotatably connected to the frame. The positioning turntable, upper turntable, and lower turntable are arranged sequentially from top to bottom and coaxially connected to the rotating shaft. Each of the positioning turntable, upper turntable, and lower turntable has multiple positioning holes, multiple upper notches, and multiple lower notches evenly distributed around its circumference. All positioning holes, upper notches, and lower notches are arranged facing each other. The combined device has at least a loading station, a centering station, a pressing station, and a unloading station. All positioning holes, upper notches, and lower notches sequentially pass through the loading station, the centering station, and the pressing station. The machine includes a pressing station and a unloading station. A fixed upper pad is provided between the upper turntable and the lower turntable, and the upper pad is located at the unloading station. Each pressing rod is slidably connected to the corresponding positioning hole in the vertical direction. Each pressing rod has a pressing block at its lower end, and the pressing block has a negative pressure suction head. The frame has an upper rail above the positioning turntable. The upper rail is located on the moving path of the pressing rod. The upper end of the pressing rod is in contact with the upper rail. The upper rail has a lower convex section. The lower inclined position of the lower convex section is located at the centering station, and the lower limit position of the lower convex section is located at the pressing station.

[0007] A plastic cap conveying device is provided with a first conveying mechanism, which is connected to the lower opening of the loading station;

[0008] An aluminum cap conveying device is provided with a second conveying mechanism, which is connected to the upper opening of the loading station.

[0009] The combined cap production equipment according to the embodiments of this utility model has at least the following beneficial effects: During production, the plastic cap conveying device provides plastic caps one by one to the lower notch of the downward turntable, and the aluminum cap conveying device provides aluminum caps one by one to the upper notch of the upward turntable. In the loading station, the aluminum cap is placed on the upper pad plate and located above the plastic cap. As the rotating shaft rotates, both the aluminum cap and the plastic cap in the loading station are moved to the centering station. The corresponding pressing rod moves to the lower inclined position of the lower convex section, so that the pressing rod can abut against the upper surface of the aluminum cap and adsorb the aluminum cap. At this time, the aluminum cap and the plastic cap are centered in the vertical direction. As the rotating shaft rotates further, the centering station... Both the aluminum cap and the plastic cap are moved to the pressing station. The pressing rod at the corresponding position moves to the lower limit of the lower protrusion. During this process, the pressing rod presses the aluminum cap downward into the plastic cap to achieve the assembly of the aluminum cap and the plastic cap. As the rotating shaft rotates further, the combined cap in the pressing station is moved to the unloading station. During this process, the pressing rod at the corresponding position stops adsorbing the aluminum cap and moves upward away from the combined cap. The combined cap is carried away from the lower notch of the unloading station by the rotation of the rotating shaft. Compared with the prior art, this utility model can realize the automated and standardized production of combined caps, greatly improve the production efficiency of combined caps, and thus meet the requirements of mass production.

[0010] According to some embodiments of this utility model, since the distance between the upper turntable and the lower turntable is small, it is impossible to accommodate the first conveying mechanism and the second conveying mechanism at the same time. Therefore, the docking position of the first conveying mechanism and the lower opening is misaligned at the docking position of the second conveying mechanism and the upper opening.

[0011] According to some embodiments of this utility model, the pressing rod is provided with an airflow channel connected to the negative pressure suction head, the airflow channel is connected to a solenoid valve, and the solenoid valve is connected to a negative pressure air pipe to meet the electronic control of the adsorption function.

[0012] According to some embodiments of this utility model, each of the pressing rods has a boss above the positioning turntable, and a spring connects the boss to the positioning turntable. The spring has a spring force that drives the pressing rod to move upward. Since the vertical position of the positioning turntable is fixed, the spring can only push the pressing rod to move upward, thereby ensuring that the pressing rod remains in contact with the upper track.

[0013] According to some embodiments of the present invention, in order to reduce the friction coefficient between the pressing rod and the upper track, each pressing rod is provided with a rolling friction element at its upper end, and the rolling friction element abuts against the upper track.

[0014] According to some embodiments of this utility model, the plastic cap conveying device includes a first hopper and a first lifting conveyor belt. The first lifting conveyor belt passes through the first hopper from bottom to top. Multiple first support strips are horizontally arranged along the length of the first lifting conveyor belt. The plastic cap conveying device has a first turning point at the rising position of the first lifting conveyor belt. The first turning point is used to screen out plastic caps with non-preset orientations. The first turning point can be an inclined surface or a protrusion. Since the two orientations of the plastic cap have different center of gravity directions, the posture of the plastic cap can be temporarily changed by setting the first turning point, thereby screening out plastic caps with non-preset orientations onto the first support strips and retaining plastic caps with the preset orientation onto the first support strips.

[0015] According to some embodiments of this utility model, the aluminum cap conveying device includes a second hopper and a second lifting conveyor belt. The second lifting conveyor belt passes through the second hopper from bottom to top. Multiple second support strips are transversely arranged along the length of the conveying surface of the second lifting conveyor belt. The aluminum cap conveying device has a second turning point at the rising position of the second lifting conveyor belt. The second turning point is used to screen out aluminum caps with non-preset orientations. The second turning point can be an inclined surface or a protrusion. Since the two orientations of the aluminum cap have different center of gravity directions, the position of the aluminum cap can be changed by setting the second turning point, thereby screening out aluminum caps with non-preset orientations on the second support strips and retaining aluminum caps with the preset orientation on the second support strips.

[0016] According to some embodiments of this utility model, the combined cap production equipment further includes a material unloading device, which has a material unloading channel that connects to the lower notch of the unloading station. The assembled combined cap is transferred to the material unloading channel, and the material unloading device unloads the combined cap into the material frame.

[0017] According to some embodiments of this utility model, in order to screen out defective products, a detection unit and a blowing mechanism are provided on the material feeding channel. The detection unit is used to detect defective products, and the blowing mechanism is electrically connected to the detection unit. When a defective bottle cap without an aluminum cap or a plastic cap passes through the detection unit, the detection unit feeds back a detection signal to the controller. Subsequently, the controller controls the blowing mechanism to blow air, and the blowing mechanism blows the defective bottle cap toward the waste bin.

[0018] According to the second aspect of the present invention, the aluminum-plastic composite cover is produced by the aforementioned composite cover production equipment.

Detailed Implementation

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] like Figure 2 and Figure 6 As shown, the combined cap production equipment according to a first aspect embodiment of the present invention includes a combination device 100, a plastic cap conveying device 200, an aluminum cap conveying device 300, and a material unloading device 400. The plastic cap conveying device 200 includes a first hopper 210 and a first lifting conveyor belt 220. The first hopper 210 stores plastic caps 510 to be conveyed. The first lifting conveyor belt 220 is driven by a first lifting motor 230. The bottom of the first hopper 210 has a first opening 211, which is covered by the first lifting conveyor belt 220. The first lifting conveyor belt 220 is arranged generally from bottom to top and has a bottom-up conveying path. Multiple first support strips 221 are transversely arranged along the length of the conveying surface of the first lifting conveyor belt 220. The width of each first support strip 221 is only sufficient to accommodate the thickness of one plastic cap 510, and the distance between two adjacent first support strips 221 is greater than the outer diameter of one plastic cap 510. When the first lifting motor 230 starts, it drives the first lifting conveyor belt 220 to pass from bottom to top through the first hopper 210. Part of the plastic cover 510 inside the first hopper 210 will be supported by the first support bar 221 and move upward with the first support bar 221.

[0033] Since the plastic cap 510 has two different orientations, one of which is that the cap opening faces away from the first lifting conveyor belt 220, and the other of which is that the cap opening faces the first lifting conveyor belt 220, when the plastic cap 510 with the cap opening facing the first lifting conveyor belt 220 is conveyed to the assembly device 100, the opening of the plastic cap 510 is facing downwards, and it cannot participate in subsequent processing. Therefore, in this embodiment, this orientation is defined as a non-preset orientation, while the orientation with the cap opening facing away from the first lifting conveyor belt 220 is defined as a preset orientation.

[0034] To screen out plastic caps 510 with non-preset orientations, the plastic cap conveying device 200 has a first turning point 222 at the rising position of the first lifting conveyor belt 220. The first turning point 222 can be an inclined surface or a protrusion. Since the two orientations of the plastic caps 510 have different center of gravity directions, the posture of the plastic caps 510 can be temporarily changed by setting the first turning point 222, so that plastic caps 510 that cannot be placed stably in this posture can roll down to the first hopper 210, thereby retaining the plastic caps 510 with the preset orientation on the first support bar 221. When the plastic caps 510 with the preset orientation are lifted to a specified height, the plastic cap conveying device 200 is provided with a first air nozzle (not shown in the figure) at this height, so as to blow the plastic caps 510 with the preset orientation into the first conveying mechanism 240, thereby providing plastic caps 510 one by one to the assembly device 100.

[0035] Similarly, the aluminum cap conveying device 300 includes a second hopper 310 and a second lifting conveyor belt 320. The second hopper 310 is used to store aluminum caps 520 to be conveyed. The second lifting conveyor belt 320 is driven by a second lifting motor. The bottom of the second hopper 310 has a second opening, which is covered by the second lifting conveyor belt 320. The second lifting conveyor belt 320 is arranged generally from bottom to top and has a bottom-up conveying path. Multiple second support bars are transversely arranged along the length of the conveying surface of the second lifting conveyor belt 320. The width of the second support bars can only accommodate the thickness of one aluminum cap 520, and the distance between two adjacent second support bars is greater than the outer diameter of one aluminum cap 520. When the second lifting motor starts, it drives the second lifting conveyor belt 320 from bottom to top through the second hopper 310. Some of the aluminum caps 520 in the second hopper 310 are supported by the second support bars and move upward with the second support bars.

[0036] Since the aluminum cap 520 has two different orientations, one of which is that the cap opening faces away from the second lifting conveyor belt 320, and the other of which is that the cap opening faces the second lifting conveyor belt 320, when the aluminum cap 520 with the cap opening facing the second lifting conveyor belt 320 is conveyed to the assembly device 100, the opening of the aluminum cap 520 is facing downwards, and it cannot participate in subsequent processing. Therefore, in this embodiment, this orientation is defined as a non-preset orientation, while the orientation with the cap opening facing away from the second lifting conveyor belt 320 is defined as a preset orientation.

[0037] To screen out aluminum caps 520 with non-preset orientations, the aluminum cap conveying device 300 has a second turning point at the rising position of the second lifting conveyor belt 320. The second turning point can be an inclined surface or a protrusion. Since the two orientations of the aluminum caps 520 have different center of gravity directions, the posture of the aluminum caps 520 can be temporarily changed by setting the second turning point, allowing aluminum caps 520 that cannot be placed stably in that posture to roll down to the second hopper 310, thereby retaining the aluminum caps 520 with the preset orientation on the second support bar. When the aluminum caps 520 with the preset orientation are lifted to a designated height, the aluminum cap conveying device 300 is provided with a second air nozzle at that height to blow the aluminum caps 520 with the preset orientation into the second conveying mechanism 340, thereby providing aluminum caps 520 to the assembly device 100 one by one.

[0038] like Figure 3 and Figure 4 As shown, the combined device 100 includes a frame 110, a rotating shaft 120, a lower turntable 130, an upper turntable 140, a positioning turntable 150, and multiple pressing rods 160. The frame 110 serves as the mounting reference for all components, and its position is fixed relative to the ground. The rotating shaft 120 is arranged vertically and is rotatably connected to the center of the frame 110 via bearings. A rotary motor for driving the rotating shaft 120 is located at the top of the frame 110. The lower turntable 130, upper turntable 140, and positioning turntable 150 are all movable components that rotate relative to the frame 110. The lower turntable 130, upper turntable 140, and positioning turntable 150 are arranged sequentially from bottom to top, and all three are fixedly connected to the rotating shaft 120 via connectors. They all rotate around the central axis of the rotating shaft 120, thereby ensuring the synchronous rotation of the lower turntable 130, upper turntable 140, and positioning turntable 150.

[0039] Specifically, the positioning turntable 150 has multiple positioning holes 151 evenly distributed around its circumference, the upper turntable 140 has multiple upper notches 141 evenly distributed around its circumference, and the lower turntable 130 has multiple lower notches 131 evenly distributed around its circumference. The number of positioning holes 151, upper notches 141, and lower notches 131 is the same, and their positions are arranged one to one opposite each other in the vertical direction. The positioning holes 151 are not connected to the outer peripheral wall of the positioning turntable 150, while the upper notches 141 are connected to the outer peripheral wall of the upper turntable 140, and the lower notches 131 are connected to the outer peripheral wall of the lower turntable 130. In this embodiment, there are eight positioning holes 151, eight upper notches 141, and eight lower notches 131, each corresponding to one of the eight numbered positions. However, since some stations require multiple numbered positions, the assembly device 100 has six stations: a loading station, a centering station, a pressing station, a first transition station, a unloading station, and a second transition station. All positioning holes 151, upper notches 141, and lower notches 131 pass sequentially through the loading station, the centering station, the pressing station, the first transition station, the unloading station, and the second transition station, and then return to the loading station in a loop.

[0040] The first conveying mechanism 240 of the plastic cap conveying device 200 is connected to the lower opening 131 of the loading station. When the plastic cap 510 in the lower opening 131 is rotated to the next numbered position by the lower turntable 130, the lower opening 131 at the previous numbered position will rotate to connect with the first conveying mechanism 240, thereby realizing the sequential feeding of plastic caps 510. The second conveying mechanism 340 of the aluminum cap conveying device 300 is connected to the upper opening 141 of the loading station. When the aluminum cap 520 in the upper opening 141 is rotated to the next numbered position by the upper turntable 140, the upper opening 141 at the previous numbered position will rotate to connect with the second conveying mechanism 340, thereby realizing the sequential feeding of aluminum caps 520.

[0041] In the loading station, since the initial positions of the aluminum cover 520 and the plastic cover 510 are not properly positioned, an upper pad 170 needs to be set between the upper turntable 140 and the lower turntable 130. The upper pad 170 is fixedly connected to the frame 110 and will not rotate with the rotation of the shaft 120. The upper pad 170 is used to separate the aluminum cover 520 and the plastic cover 510 to prevent the aluminum cover 520 from falling into the plastic cover 510 during loading.

[0042] At least in the loading station, centering station, pressing station and first transition station, a lower pad 180 is provided below the lower turntable 130. The lower pad 180 is connected to the upper pad 170. The lower pad 180 does not rotate with the rotation of the shaft 120. The lower pad 180 is used to provide reliable support for the plastic cover 510 and prevent the plastic cover 510 from falling down from the lower notch 131.

[0043] Furthermore, since the distance between the upper turntable 140 and the lower turntable 130 is small, this distance cannot simultaneously accommodate the first conveying mechanism 240 and the second conveying mechanism 340. Therefore, the docking position of the first conveying mechanism 240 and the lower notch 131 needs to be offset from the docking position of the second conveying mechanism 340 and the upper notch 141. In other words, the loading station needs to occupy two numbered positions: one numbered position for loading the aluminum cover 520 and the other numbered position for loading the plastic cover 510.

[0044] In addition, each pressing rod 160 is slidably connected to a corresponding positioning hole 151 in the vertical direction. A guide sleeve is provided in the positioning hole 151, and the pressing rod 160 is connected to the guide sleeve to limit the multiple degrees of freedom of the pressing rod 160. A flat position is also provided between the guide sleeve and the pressing rod 160 to restrict the rotation of the pressing rod 160 around its own axis. Each pressing rod 160 has a pressing block 161 at its lower end. The pressing block 161 may be made of polyurethane material. The pressing block 161 is provided with a negative pressure suction head (not shown in the figure). The pressing rod 160 has an airflow channel connected to the negative pressure suction head. The airflow channel is connected to a solenoid valve (not shown in the figure) at the upper part of the pressing rod 160. The solenoid valve is connected to a negative pressure air pipe to meet the electronic control of the adsorption function. When the solenoid valve is open, the negative pressure air pipe is connected to the negative pressure suction head, and the pressure block 161 of the pressure rod 160 has negative pressure suction. When the solenoid valve is closed, the negative pressure air pipe is not connected to the negative pressure suction head, and the pressure block 161 of the pressure rod 160 does not have negative pressure suction.

[0045] It should be further explained that, since all the pressing rods 160 rotate along with the positioning turntable 150, to prevent the negative pressure air pipes from being broken due to the rotation of the pressing rods 160, clearance holes (not shown in the attached drawings) are provided at multiple locations on the rotating shaft 120. All negative pressure air pipes enter the rotating shaft 120 through the corresponding clearance holes. A rotary joint is located at the center of the rotating shaft 120, connected to the main air pipe. The position of the main air pipe remains fixed, and the main air pipe is connected to multiple negative pressure air pipes via the rotary joint. When the rotating shaft 120 rotates, the multiple negative pressure air pipes, driven by the rotating shaft 120, cause the rotary joint to rotate relative to the main air pipe, thereby preventing the negative pressure air pipes from being broken due to the rotation of the pressing rods 160.

[0046] On the other side, each pressing rod 160 has a boss 162 above the positioning turntable 150. A spring 163 connects the boss 162 and the positioning turntable 150. The spring 163 can be a compression spring, with its two ends abutting against the boss 162 and the positioning turntable 150 respectively. Since the vertical position of the positioning turntable 150 is fixed, the spring 163 has an upward elastic force when compressed. Correspondingly, the frame 110 has an upper rail 600 above the positioning turntable 150. The upper rail 600 is located on the moving path of the pressing rod 160. Since the pressing rod 160 has an upward elastic force tendency, the upper end of the pressing rod 160 will always abut against the upper rail 600 regardless of how the upper rail 600 is set. To reduce the coefficient of friction between the pressing rod 160 and the upper rail 600, each pressing rod 160 has a rolling friction element 164 at its upper end, including but not limited to rollers or balls.

[0047] Furthermore, to achieve the pressing of the aluminum cover 520 and the plastic cover 510, the upper track 600 is provided with a lower convex section 610 in an arc shape. The lower convex section 610 includes a lower inclined position 611, a lower limit position 612, and an upper inclined position 613. Between the lower inclined position 611 and the lower limit position 612, the distance between the lower convex section 610 and the positioning turntable 150 gradually decreases. Between the lower limit position 612 and the upper inclined position 613, the distance between the lower convex section 610 and the positioning turntable 150 gradually increases. The upper track 600 remains horizontally positioned outside the lower convex section 610. In this embodiment, the lower inclined position 611 of the lower convex section 610 is located at the centering station, the lower limit position 612 of the lower convex section 610 is located at the pressing station, and the upper inclined position 613 of the lower convex section 610 is located at the first transition station.

[0048] Because the pressing rod 160 is in contact with the upper rail 600 under the elastic force of the spring 163, when the pressing rod 160 moves to the lower inclined position 611 of the lower convex section 610, the pressing rod 160 gradually moves downward and reaches its limit at the lower limit position 612 of the lower convex section 610; then when the pressing rod 160 moves to the upper inclined position 613 of the lower convex section 610, the pressing rod 160 gradually moves upward and maintains horizontal movement after leaving the lower convex section 610.

[0049] Using the above structure, during production, the plastic cap conveying device 200 provides plastic caps 510 one by one to the lower notch 131 of the lower turntable 130, and the aluminum cap conveying device 300 provides aluminum caps 520 one by one to the upper notch 141 of the upper turntable 140. In the loading station, the aluminum caps 520 are placed on the upper pad 170. As the rotating shaft 120 rotates, both the aluminum caps 520 and the plastic caps 510 in the loading station are moved to the centering station. The corresponding pressing rod 160 moves to the lower inclined position 611 of the lower convex section 610, so that the pressing rod 160 can abut against the upper surface of the aluminum cap 520 and adsorb the aluminum cap 520. At this time, the aluminum cap 520 and the plastic cap 510 are aligned in the vertical direction.

[0050] As the rotating shaft 120 rotates further, the aluminum cover 520 and the plastic cover 510 in the centering station are both moved to the pressing station. The pressing rod 160 in the corresponding position moves to the lower limit 612 of the lower protrusion 610. During this process, the pressing rod 160 presses the aluminum cover 520 downward into the plastic cover 510 to achieve the assembly of the aluminum cover 520 and the plastic cover 510.

[0051] As the rotating shaft 120 rotates further, the combined cover 500 in the pressing station is moved to the first transition station. The pressing rod 160 at the corresponding position moves along the upper inclined position 613 of the lower convex section 610. During this process, the pressing rod 160 stops adsorbing the aluminum cover 520 and moves upward away from the combined cover 500.

[0052] As the rotating shaft 120 rotates further, the combined cover 500 in the first transition station is moved to the unloading station, and the pressing rod 160 at the corresponding position leaves the lower protrusion 610. The combined cover 500 is carried away from the lower notch 131 of the unloading station by the rotation of the rotating shaft 120.

[0053] like Figure 2 As shown, the unloading device 400 is provided with an unloading channel 410, which can be a conveyor belt. The unloading channel 410 is connected to the lower opening 131 of the unloading station. The assembled combined cover 500 is transferred to the unloading channel 410, and the unloading device 400 is used to unload the combined cover 500 into the material frame 420.

[0054] Furthermore, to screen out defective products, the material feeding channel 410 is equipped with a detection unit 430 and a blowing mechanism 440. The detection unit 430 can be a vision sensor, and the blowing mechanism 440 can be an electrically controlled blower. The blowing mechanism 440 is electrically connected to the detection unit 430. When a defective bottle cap without an aluminum cap 520 or a plastic cap 510 passes through the detection unit 430, the detection unit 430 feeds back a detection signal to the controller. After analyzing the detection signal, the controller generates a blowing command, and then controls the blowing mechanism 440 to blow air, which blows the defective bottle cap towards the waste bin 450. Conversely, the blowing mechanism 440 will not blow air on qualified combination caps 500, allowing the qualified combination caps 500 to pass smoothly through the downstream counting unit 460. The counting unit 460 is used to count the number of combination caps 500 for subsequent packaging.

[0055] In some embodiments, the detection unit 430 may be a proximity switch, which is used only to detect the aluminum cap 520. When a defective bottle cap without the aluminum cap 520 passes the detection unit 430, the detection unit 430 feeds back a detection signal to the controller. After analyzing the detection signal, the controller generates a blowing command, and then controls the blowing mechanism 440 to blow air, which blows the defective bottle cap toward the waste bin 450.

[0056] like Figure 5As shown, furthermore, to ensure that the combined cover 500 can smoothly leave the lower notch 131 of the lower turntable 130 in the unloading station, a discharge stop 190 is provided between the upper turntable 140 and the lower turntable 130. The discharge stop 190 is located between the unloading station and the second transition station. The discharge stop 190 is fixedly connected to the frame 110 and will not rotate with the rotation of the rotating shaft 120. The discharge stop 190 is located on the movement path of the combined cover 500. When the combined cover 500 is rotated to the unloading station, even if the combined cover 500 moves to the next station with the lower turntable 130, it will be intercepted by the discharge stop 190 when it passes the discharge stop 190. The discharge stop 190 forcibly pulls the combined cover 500 away from the lower notch 131 of the lower turntable 130, and finally the combined cover 500 is received by the discharge channel 410.

[0057] Since the combined cover 500 has multiple possible positions on the material drop channel 410, but the position of the detection unit 430 is fixed, in order to ensure that the detection unit 430 can detect all the combined covers 500, a guide 470 can be provided on the material drop channel 410. The guide 470 is inclined along the length of the material drop channel 410, and the end of the guide 470 is close to the detection unit 430, so that the guide 470 can guide the combined covers 500 at each position to the position of the detection unit 430, thereby avoiding the occurrence of missed detection.

[0058] like Figure 3 As shown, in some embodiments of this utility model, since the aluminum cover 520 in the upper notch 141 only exists at the loading station, in order to confine the aluminum cover 520 within the upper notch 141 during rotation and prevent it from being thrown out of the upper notch 141 due to centripetal force, the frame 110 is provided with an upper baffle 171 on the periphery of the upper turntable 140. The upper baffle 171 is located at the loading station. Under the combined constraint of the upper baffle 171 and the upper notch 141, the aluminum cover 520 remains relatively stationary with respect to the corresponding lower notch 131 until the pressing rod 160 downwardly attracts the aluminum cover 520.

[0059] In some embodiments of this utility model, since the plastic cover 510 in the lower notch 131 only exists between the loading station and the first transition station, in order to confine the plastic cover 510 within the lower notch 131 during rotation and prevent it from being thrown out of the lower notch 131 due to centripetal force, the frame 110 is provided with a lower baffle 181 on the periphery of the lower turntable 130. The lower baffle 181 is located between the loading station and the first transition station. Under the joint confinement of the lower baffle 181 and the lower notch 131, the plastic cover 510 remains relatively stationary with respect to the corresponding upper notch 141 until the combined cover 500 is unloaded into the discharge channel 410. Specifically, the upper baffle 171 is fixedly connected to the upper pad 170, and the lower baffle 181 is fixedly connected to the lower pad 180, so that both the upper baffle 171 and the lower baffle 181 are relatively stationary on the frame 110.

[0060] It is understandable that the first and second transition stations mentioned above are not necessary stations. When the number of numbered stations decreases, the first and / or second transition stations can be removed accordingly.

[0061] The aluminum-plastic composite cover according to the second aspect of the present invention is produced by the composite cover production equipment described in the first aspect of the present invention.

[0062] Since the aluminum-plastic composite cover adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0063] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
