Description

Technical Field

[0001] This utility model relates to the field of automatic packaging technology, and in particular to a cap feeding mechanism and an automatic capping machine. Background Technology

[0002] Gun caps, often referred to as pump caps, consist of a cap body and a pump tube located at the bottom of the cap body. A discharge nozzle is located on one side of the upper part of the cap body, and a pump assembly is located inside. The pump assembly connects the discharge nozzle and the pump tube to achieve press-to-dispense dispensing, and it is widely used in the daily chemical industry. Currently, due to the unique structure of gun caps (irregular shape), most capping of gun cap bottles still involves manually placing the cap on the corresponding bottle and then tightening it using a capping machine. This results in low overall efficiency and low output. Chinese invention patent CN 115159419 B discloses a capping machine and method for pump caps. While it achieves automatic capping, its overall structure is complex, manufacturing costs are high, and its applicability is limited. Utility Model Content

A positioning piece installed on the capping body is detachably provided in the gripping jaw of the gripper assembly. The positioning piece is provided with a positioning groove adapted to the cap. A fixed origin photoelectric detector is also provided on the side of the capping body. The origin photoelectric detector is suitable for determining the rotation angle of the positioning piece by monitoring the rotation angle of the capping body.

[0012] Furthermore, the tube-strapping mechanism includes a second linear module located below the first linear module, a first slide block that can be raised and lowered via the second linear module, a finger cylinder fixed on the first slide block, and a pair of clamps that can be opened and closed via the finger cylinder, with a clamping opening between the two clamps that is adapted to the pump tube of the gun cover.

Detailed Implementation

[0034] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0035] (Example 1)

[0036] like Figures 1 to 5The automatic capping machine shown includes a frame and at least one automatic capping line extending into the frame. This embodiment has two automatic capping lines sharing one frame, thereby increasing production capacity. The automatic capping line includes a cap feeding mechanism 1, a cap feeding mechanism 2, a capping mechanism 3, a tube straightening mechanism 4, a bottle feeding mechanism 5, and a bottle holding mechanism 6. The capping mechanism 3, the tube straightening mechanism 4, and the bottle feeding mechanism 5 are arranged sequentially from top to bottom. The cap feeding mechanism 1 and the bottle holding mechanism 6 are located on both sides of the capping mechanism. The cap feeding mechanism 2 is fixedly mounted at the end of the cap feeding mechanism. The caps are sent to the cap feeding mechanism 1 manually or by an automatic cap sorting machine. The cap feeding mechanism 2 transfers the caps from the cap feeding mechanism 1 to the capping mechanism 3. At the same time, the bottle feeding mechanism 5 sends the bottles to the capping mechanism 3. The capping mechanism 3 and the bottle holding mechanism 6 clamp the caps and bottles respectively. The tube straightening mechanism 4 straightens the pump tube of the cap so that the pump tube is accurately inserted into the bottle. Finally, the capping mechanism 3 automatically caps the bottles. The overall structure is simple, the manufacturing cost is low, labor costs are saved, packaging efficiency is improved, and it has a wide range of applications.

[0037] Specifically, the cap feeding mechanism 1 includes two parallel belt conveyors 1-1 spaced apart, forming a conveying channel suitable for placing the gun cap. During conveying, the pump pipe gap of the gun cap is inserted into the gap between the two belt conveyors 1-1, and the two sides of the cap rest on the conveying plane of the belt conveyors 1-1 respectively, achieving forward movement. A positioning baffle 1-2 extending along the conveying direction is fixedly mounted above the conveying channel. The positioning baffle 1-2 has downwardly extending sidewalls on both sides to limit the tilt angle of the gun cap. At the end of the conveying channel, a first baffle assembly 1-3, a second baffle assembly 1-4, and a third baffle assembly 1-5 are sequentially and adjustable along the conveying direction. Specifically, a first mounting plate 1-6 is fixedly provided on the end side of the conveying channel. A strip groove extending along the conveying direction is provided on the first mounting plate 1-6. The first cover assembly 1-3, the second cover assembly 1-4 and the third cover assembly 1-5 have the same structure, including a cylinder seat that is adjustablely mounted on the strip groove by bolts. A needle cylinder that is horizontally set and vertically extended to the conveying channel is fixedly mounted on the cylinder seat.

[0038] The needle cylinders of the first cover assembly 1-3 and the second cover assembly 1-4 form a gap suitable for placing a single gun cover. The first cover assembly 1-3 blocks subsequent conveyed gun covers, allowing only one gun cover to enter the first cover assembly 1-3 and the second cover assembly 1-4. At this time, the second cover assembly 1-4 opens, and the gun cover is sent to the third cover assembly 1-5. After the transfer, the second cover assembly 1-4 closes, the first cover assembly 1-3 opens, and another gun cover enters. This action is repeated to achieve the sequential delivery of gun covers.

[0039] To prevent gun caps from stacking during transport, this embodiment includes a liftable pressure plate 1-7 within the inner cavity of the positioning baffle 1-2. Specifically, multiple brackets 1-8 are fixedly mounted on the side of the conveying channel. Each bracket 1-8 has a quick-adjusting screw 1-9, and the top of the pressure plate 1-7 has a threaded post that matches the quick-adjusting screw 1-9. The quick-adjusting screw passes through the positioning baffle and is threaded into the corresponding threaded post. This allows for height adjustment of the pressure plate, limiting the height of the gun caps to meet the transport requirements of gun caps of different heights, preventing stacking of gun caps due to compression, and improving the stability of gun cap transport.

[0040] The cap feeding mechanism 2 includes a third linear module 2-1, a first slide block 2-2, a first double-headed cylinder 2-3, a first clamping plate 2-4, and a first clamping block 2-5. The third linear module 2-1 is horizontally positioned and fixedly mounted on the belt conveyor 1-1. The first slide block 2-2 is horizontally movable via the third linear module 2-1. The first double-headed cylinder 2-3 is fixedly mounted at the bottom of the first slide block 2-2. A pair of first clamping plates 2-4 are provided, respectively fixedly connected to the two piston ends of the first double-headed cylinder 2-3 to achieve opening and closing motion. Two first clamping blocks 2-5 are provided, respectively fixedly mounted at the ends of the two first clamping plates 2-4. A single double-headed cylinder can drive a pair of clamping plates, which in turn clamp the cap via the clamping blocks. The linear module then drives the slide block to reciprocate, achieving cap transfer and simplifying the structure.

[0041] A screw jack 7 is fixedly installed inside the frame. The bottle-holding mechanism 6 includes a second mounting plate 6-1 fixedly connected to the lifting part of the screw jack 7 and a locking block connected to the fixed part of the screw jack 7. A second double-headed cylinder 6-2 is fixedly installed at the end of the second mounting plate 6-1. The two piston ends of the second double-headed cylinder 6-2 are respectively fixedly connected to opposing second clamping plates 6-3. A second clamping block 6-4 is fixedly installed at the end of the second clamping plate 6-3, thereby realizing the bottle-holding action. The height of the bottle-holding mechanism 6 is adjustable through the screw jack 7 to meet the bottle-holding needs of different sizes, thus increasing its versatility. When it is necessary to adjust the bottle-holding mechanism 6, the locking block is opened, and the second mounting plate 6-1 is raised and lowered by the screw jack 7. When the appropriate height is reached, the locking block is locked again. The fixed part of the screw jack 7 serves as the load-bearing mechanism, which improves the stability of the bottle-holding mechanism 6 and prevents the lifting part of the screw jack 7 from deforming and failing due to long-term load.

[0042] The frame is fixedly equipped with a column 8. The capping mechanism 3 includes a first linear module 3-1 fixedly mounted on the column 8 and a capping head that can be raised and lowered through the first linear module 3-1. The capping head includes a capping motor 3-2, a capping cylinder 3-3, a capping body 3-4 driven to rotate by the capping cylinder, and a gripper assembly 3-5 installed at the bottom of the capping body and driven to open and close by the capping cylinder. The gripper assembly 3-5 clamps the cap of the gun cover to perform subsequent capping actions.

[0043] The tube-strapping mechanism 4 includes a second linear module 4-1 located below the first linear module 3-1, a first slide block 4-2 that can be raised and lowered via the second linear module 4-1, a finger cylinder 4-3 fixed on the first slide block 4-2, and a pair of clamping plates 4-4 that can be opened and closed via the finger cylinder 4-3. The two clamping plates form a clamping opening that is compatible with the pump tube of the gun cap. The two clamping plates are clamped by the pneumatic finger, and the pneumatic finger is raised and lowered by the linear module, thereby realizing the tube-strapping function and facilitating the precise insertion of the pump tube into the bottle.

[0044] The gripper assembly 3-5 has a detachable positioning piece 3-6 installed on the capping body. The positioning piece 3-5 has a positioning groove that matches the gun cap. At the same time, the side of the capping body 3-4 is also equipped with a fixed origin photoelectric detector 3-7. When the gun cap is tightened, the positioning piece 3-5 holds the head of the gun cap. The origin photoelectric detector 3-7 monitors the rotation angle of the capping body to determine the current rotation angle of the positioning piece, and then straightens it, eliminating the need for subsequent manual operation.

[0045] This invention achieves automatic cap delivery using two belt conveyors and limits the cap's position with positioning baffles to prevent tilting during transport, thus realizing automatic cap feeding and laying the foundation for automatic capping. By adding positioning plates and origin photoelectric detectors to the capping mechanism, the cap head is automatically aligned, eliminating manual operation and improving overall packaging efficiency.

[0046] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
