Description

Technical Field

[0001] This invention relates to the technical field of aluminum foil sealing detection and rejection devices for bottled products, specifically an aluminum foil-free rejection device. Background Technology

[0002] Bottled liquids are a common form of packaging, widely used in the beverage, food, and pharmaceutical industries. To ensure product quality and safety, aluminum foil sealing technology is typically used to seal the bottle opening, preventing external contamination and liquid leakage.

[0003] However, existing aluminum foil sealing equipment is prone to omissions in actual use, resulting in a small number of bottled liquids not being sealed. Therefore, a rejection device is needed during the production process to remove unsealed bottled liquids.

[0004] In the process of rejecting unsealed bottled liquids, aluminum foil detection sensors are typically used to detect the liquid. When no aluminum foil seal is detected, a rejection device pushes the liquid outward in the conveying direction, causing it to fall into a collection tank, thus rejecting the unsealed bottle. However, this method results in direct spillage of the liquid, leading to contamination and waste.

[0005] Therefore, this application designs an aluminum foil-free rejection device to reject unsealed bottled liquids, solving the problem of liquid waste caused by existing rejection devices and reducing cost waste. Summary of the Invention

[0006] To address the above problems, the present invention provides an aluminum foil-free rejection device.

[0007] The technical solution adopted by the present invention to solve its technical problem is: an aluminum foil-free rejection device, including a conveying part, a rejection part and a carrying plate are provided on one side of the conveying part, the rejection part includes a support column and a horizontally arranged rejection component, the rejection component is rotatably connected to the support column, and the rejection component is horizontally arranged on the upper side of the conveying part;

[0008] The rejection assembly includes a support arm rotatably connected to the support column and a rejection seat disposed on the lower side of the support arm. The rejection seat has a clamping cavity with a bottom opening inside. Several clamping assemblies are rotatably connected inside both sides of the clamping cavity. A clamping motor is connected to the axial direction of the clamping assembly. A figure-eight damping patch is provided on the upper side of the clamping assembly.

[0009] As an optimization, several telescopic rods are fixed on the upper side of the support arm, and the extended ends of the telescopic rods are fixedly connected to the top of the rejection seat.

[0010] The clamping cavity is elongated, and several clamping components are evenly arranged along the length of the clamping cavity. The inner wall of the clamping cavity is recessed to form several connecting grooves, and the clamping components are rotatably connected to the connecting grooves.

[0011] As an optimization, the clamping assembly is located at the lower part of the clamping cavity. The clamping assembly includes a connecting plate and a clamping roller. The connecting plate is rotatably connected to the clamping cavity. The clamping motor is fixed to the outside of the rejection seat. The output shaft of the clamping motor has a hexagonal hole inside. A hexagonal prism is connected to the axis of the connecting plate. The hexagonal prism is slidably connected to the output shaft of the clamping motor. The hexagonal prism has a cavity inside. A support spring is connected between the inside of the hexagonal prism and the inside of the hexagonal hole.

[0012] The connecting plate has a recessed groove on the side away from the clamping motor to form several mounting grooves. The clamping roller is rotatably connected to the mounting groove, and a drive motor is connected to the axis of the clamping roller.

[0013] As an optimization, the number of clamping rollers on each connecting plate is not less than 3, adjacent clamping rollers are arranged in parallel, the length of the clamping rollers is less than the length of the mounting groove, and the minimum distance between two adjacent clamping components is less than the outer diameter of the bottle mouth of the aluminum foil-free bottle.

[0014] As an optimization, a rotary motor is provided at the top of the support column, the output shaft of the rotary motor is fixedly connected to the end of the support arm, and the end of the clamping cavity away from the rotary motor is open.

[0015] As an optimization, the opening width of the damping patch is greater than the outer diameter of the bottle opening of the aluminum foil-free bottle, the minimum width of the damping patch is less than the inner diameter of the bottle opening of the aluminum foil-free bottle, the thickness of the damping patch is not less than the thickness of the aluminum foil-free bottle, and the damping patch is made of elastic material.

[0016] As an optimization, the conveying section includes a conveyor belt and a drive roller for driving the conveyor belt to move, and a conveying bracket is provided on the lower side of the rejection section, with the drive roller fixedly connected to the conveying bracket.

[0017] As an optimization, the carrier tray is arranged adjacent to the rejection section, the length of the carrier tray is greater than the length of the rejection seat, the carrier tray is located below the rejection seat, and the distance between the bottom of the carrier tray and the rejection seat is greater than the height of the aluminum foil-free bottle.

[0018] The beneficial effects of this solution are that an aluminum foil-free rejection device has the following advantages:

[0019] This application removes aluminum foil-free bottles by removing a portion and temporarily clamps the aluminum foil-free bottles. When multiple aluminum foil-free bottles are clamped in the removal portion, the aluminum foil-free bottles are placed together in the carrier tray, which can effectively prevent the waste of liquid, facilitate the secondary packaging of aluminum foil-free bottles, and save production costs.

[0020] This application features a rotatably connected clamping assembly inside the rejection seat. The clamping assembly not only clamps the aluminum foil-free bottles but also allows the aluminum foil-free bottles to move within the clamping cavity, facilitating the simultaneous rejection of multiple aluminum foil-free bottles and improving the efficiency of the device.

[0028] like Figure 1 , 6 As shown, an aluminum foil-free rejection device includes a conveying section 1. A rejection section and a carrier plate 2 are provided on one side of the conveying section 1. The rejection section includes a support column 3 and a horizontally arranged rejection component. The rejection component is rotatably connected to the support column 3 and is horizontally arranged on the upper side of the conveying section 1.

[0029] The rejection assembly includes a support arm 4 rotatably connected to the support column 3 and a rejection seat 5 disposed on the lower side of the support arm 4. The rejection seat 5 has a clamping cavity 6 with a bottom opening inside. Several clamping assemblies are rotatably connected inside both sides of the clamping cavity 6. A clamping motor 7 is connected to the axial direction of the clamping assembly. A figure-eight damping patch 8 is provided on the upper side of the clamping assembly.

[0030] The support arm 4 is fixedly connected to the top of the rejection seat 5. The end of the clamping cavity 6 away from the conveying part 1 should be closed to prevent the aluminum foil-free bottle 12 from slipping out of the clamping cavity 6.

[0031] like Figure 3 , 6 As shown, several telescopic rods 9 are fixed on the upper side of the support arm 4, and the extended ends of the telescopic rods 9 are fixedly connected to the top of the removal seat 5.

[0032] The clamping cavity 6 is elongated, and several clamping components are evenly arranged along the length of the clamping cavity 6. The inner wall of the clamping cavity 6 is recessed to form several connecting grooves, and the clamping components are rotatably connected to the connecting grooves.

[0033] like Figure 1 , 3 As shown, the clamping assembly is located at the lower part of the clamping cavity 6. The clamping assembly includes a connecting plate 10 and a clamping roller 11. The connecting plate 10 is rotatably connected to the clamping cavity 6. The clamping motor 7 is fixed to the outside of the rejection seat 5. The output shaft of the clamping motor 7 is provided with a hexagonal hole. A hexagonal prism is connected in the axial direction of the connecting plate 10. The hexagonal prism is slidably connected to the output shaft of the clamping motor 7. The hexagonal prism is provided with a cavity inside. A support spring is connected between the inside of the hexagonal prism and the inside of the hexagonal hole.

[0034] The connecting plate 10 has a recessed groove on the side away from the clamping motor 7, forming several mounting grooves. The clamping roller 11 is rotatably connected to the mounting groove, and a drive motor is connected to the axis of the clamping roller 11.

[0035] The distance between the two opposing connecting discs 10 is greater than the outer diameter of the bottle opening of the foil-free bottle body 12, which facilitates the foil-free bottle body 12 to enter between the two opposing clamping components. The distance between the clamping rollers 11 on the two opposing connecting discs 10 is less than the outer diameter of the bottle opening of the foil-free bottle body 12, which facilitates the efficient clamping of the foil-free bottle body 12 by using the clamping rollers 11.

[0036] To improve clamping efficiency, the clamping roller 11 can be made of rubber, silicone or leather, and its outer surface should be frosted or roughened to increase the friction between the clamping roller 11 and the aluminum foil-free bottle body 12.

[0037] like Figure 3 As shown, the number of clamping rollers 11 on each connecting plate 10 is not less than 3, the adjacent clamping rollers 11 are arranged in parallel, the length of the clamping roller 11 is less than the length of the mounting groove, and the minimum distance between two adjacent clamping components is less than the outer diameter of the bottle mouth of the aluminum foil-free bottle body 12.

[0038] The length of the clamping roller 11 is not less than the diameter of the bottle mouth of the aluminum foil-free bottle body 12.

[0039] like Figure 3 , 5As shown, a rotary motor 13 is provided at the top of the support column 3, and the output shaft of the rotary motor 13 is fixedly connected to the end of the support arm 4. The clamping cavity 6 is open at the end away from the rotary motor 13.

[0040] The clamping motor 7 can drive the connecting plate 10 to rotate, so that the clamping roller 11 is in a vertical, horizontal or inclined state. When it is necessary to transport the aluminum foil-free bottle 12 between adjacent clamping assemblies, the conveying rollers in the adjacent clamping assemblies are all inclined and rotate in the same direction.

[0041] like Figure 6 As shown, the opening width of the damping patch 8 is greater than the outer diameter of the bottle mouth of the aluminum foil-free bottle body 12, the minimum width of the damping patch 8 is less than the inner diameter of the bottle mouth of the aluminum foil-free bottle body 12, the thickness of the damping patch 8 is not less than the thickness of the aluminum foil-free bottle body 12, and the damping patch 8 is made of elastic material.

[0042] like Figure 1 As shown, the conveying section includes a conveyor belt and a drive roller for driving the conveyor belt to move. The lower side of the rejection section is provided with a conveying bracket, and the drive roller is fixedly connected to the conveying bracket.

[0043] like Figure 1 , 2 As shown, the carrier plate 2 is arranged adjacent to the rejection section. The length of the carrier plate 2 is greater than the length of the rejection seat 5. The carrier plate 2 is located on the lower side of the rejection seat 5. The distance between the bottom of the carrier plate 2 and the rejection seat 5 is greater than the height of the aluminum foil-free bottle body 12.

[0044] In practical use, an aluminum foil detection sensor is installed at the bottom or front of the rejection section. The installation position of the aluminum foil detection sensor can be set according to the height of the product. A rotation sensor for detecting the movement of the conveyor section 1 can also be installed. A data processing module is provided to process the detection data from the rotation sensor and the aluminum foil detection sensor, driving the rejection section to operate. The selection of the aforementioned sensors and data processing module is based on the usage habits of those skilled in the art and will not be elaborated further here.

[0045] How to use:

[0046] In practical use, the device uses an aluminum foil detection sensor to detect whether the bottle has an aluminum foil seal.

[0047] The clamping motor 7 operates, causing the clamping assembly that is not clamping the aluminum foil-free bottle 12 to rotate until the clamping roller 11 is in an inclined state.

[0048] When the aluminum foil detection sensor detects the presence or absence of aluminum foil in the bottle 12, the telescopic rod 9 extends, causing the rejection seat 5 to extend downwards, allowing the aluminum foil-free bottle 12 to enter the clamping cavity 6.

[0049] The drive motor drives the clamping roller 11 to rotate, and the clamping roller 11 drives the aluminum foil-free bottle 12 to move to the side adjacent to the rejection seat 5 and the rotary motor 13 until the aluminum foil-free bottle 12 moves to the bottom of the clamping cavity 6. The clamping motor 7 at the bottom operates, so that the clamping roller 11 at this position is in a horizontal state, and the aluminum foil-free bottle 12 is driven upward, so that the bottle mouth of the aluminum foil-free bottle 12 extends into the damping patch 8 to prevent the aluminum foil-free bottle 12 from falling.

[0050] As the rejection assembly continues to reject other aluminum foil-free bottles 12, the aluminum foil-free bottles 12 are gradually moved away from the conveying section 1 along the clamping cavity 6 until the inside of the clamping cavity 6 is filled with aluminum foil-free bottles 12.

[0051] The telescopic rod 9 is shortened, so that the last aluminum foil-free bottle 12 leaves the conveying section 1. The rotary motor 13 drives the support arm 4 to rotate, so that the rejection seat 5 moves to the upper side of the carrier plate 2.

[0052] The telescopic rod 9 extends, placing the aluminum foil-free bottle 12 on the support plate. The drive motor rotates, and the clamping roller 11 rotates, causing the aluminum foil-free bottle 12 to move downwards and be placed on the support plate 2, thus completing the removal of the aluminum foil-free bottle 12.

[0053] The rotary motor 13 actuates the support arm 4 and the rejection seat 5 to rotate to the upper side of the conveying section 1, and the rejection of aluminum foil-free bottles 12 can continue.

[0054] The above-described specific embodiments are merely specific examples of the present invention. The patent protection scope of the present invention includes, but is not limited to, the product form and style of the above-described specific embodiments. Any aluminum foil rejection device that conforms to the claims of the present invention and any appropriate changes or modifications made to it by a person skilled in the art should fall within the patent protection scope of the present invention.
