Description

Technical Field

[0001] This utility model belongs to the field of bottle cap pressing technology, and specifically relates to a pressing device for aluminum-plastic bottle caps. Background Technology

[0002] As a key component in the packaging of pharmaceuticals, food, and other products, the quality of aluminum-plastic bottle caps directly affects the product's sealing performance, safety, and appearance. The pressing device, through precise positioning of the cap and bottle body, stable conveying of the workpiece, and application of controllable pressure, achieves a reliable bond between the aluminum and plastic materials, making it a core piece of equipment ensuring the efficient operation of the packaging production line.

[0003] A search revealed that patent application CN202223387035.4 discloses a bottle cap pressing device, which includes a base and a limiting mechanism. A fixed seat is provided on the top of the base, and a support frame is fixedly connected to the top of the base. The limiting mechanism is disposed on the inner wall of the fixed seat and includes a connecting rod, a first clamping block, a second clamping block, a limiting rod, a sliding rod, a limiting groove, a limiting hole, a fixed block, and a first spring. The connecting rod is slidably connected to the inner wall of the fixed seat, and one end of the connecting rod is fixedly connected to the first clamping block and the second clamping block respectively. A limiting rod is fixedly connected to one side of the first clamping block. This utility model provides a bottle cap pressing device that solves the problem that some current bottle cap pressing devices lack the function of limiting the bottle body, causing the bottle body to shift during pressing, resulting in the bottle cap not achieving a sealing effect at the bottle opening and reducing work efficiency.

[0004] However, the above-mentioned bottle cap pressing device still has the following drawbacks:

[0005] The bottle caps of the aforementioned pressing device need to be manually placed into the clamping block before the pressing operation is performed. Since this operation can only press one bottle at a time, workers need to continuously pick up and drop the bottles and caps, which not only consumes a lot of manpower but also results in low production efficiency.

[0006] Therefore, we need to propose a pressing device for aluminum-plastic bottle caps to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a pressing device for aluminum-plastic bottle caps. The device uses a conveying assembly to continuously convey the bottle body and cap, while a rotating mechanism drives a first electric push rod and a vacuum suction cup to rotate at multiple angles. Combined with the telescopic function of the electric push rod, the device can accurately pick up the bottle cap and adjust it to be directly above the bottle body. This eliminates the need for manual feeding of each bottle individually, enabling batch and continuous supply of bottle bodies and caps, reducing labor costs, and improving production efficiency, thereby solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a pressing device for aluminum-plastic bottle caps, comprising a base plate, a pressing assembly for pressing the bottle cap and the bottle body installed on the base plate, a conveying assembly for conveying the bottle body and the bottle cap installed on the base plate, a limiting mechanism for fixing the bottle body installed on the base plate, and a positioning assembly for positioning the bottle body and the bottle cap installed on the base plate.

[0009] The positioning assembly includes a rotating mechanism, a first electric push rod, and a crossbar. The rotating mechanism is mounted on a base plate. The first electric push rod is mounted on the rotating mechanism. A crossbar is mounted on the output end of the first electric push rod. A vacuum suction cup is mounted on one end of the crossbar.

[0010] Furthermore, the rotating mechanism includes a rotating seat, which is mounted on the output end of the first electric push rod. A rotating rod is rotatably connected to the rotating seat, and one end of the rotating rod is mounted on the bottom of the first electric push rod.

[0011] Furthermore, a motor is installed on one inner wall of the rotating seat, a worm gear is installed on the output end of the motor, a worm wheel meshes with the worm gear, and the worm wheel is installed on the rotating rod.

[0012] Furthermore, the conveying assembly includes a first conveyor belt for conveying the bottle body and a second conveyor belt for conveying the bottle cap. Both the first and second conveyor belts are mounted on a base plate, and limiting mechanisms for limiting the bottle body and bottle cap are respectively provided on the first and second conveyor belts.

[0013] Furthermore, the limiting mechanism includes two sets of mounting plates, both of which are mounted on the first conveyor belt, and both sets of mounting plates are equipped with clamping mechanisms for limiting the bottle body.

[0014] Furthermore, the clamping mechanism includes a cylinder mounted on a mounting plate, the output end of the cylinder penetrating the mounting plate, and a clamping block mounted on the output end of the cylinder. A guide rod is mounted on the clamping block, and the guide rod is slidably connected to the mounting plate. The clamping block has an arc-shaped structure.

[0015] Furthermore, the pressing assembly includes a support frame, a second electric push rod is mounted on the top of the support frame, the output end of the second electric push rod passes through the support frame, and a pressure head is mounted on the output end of the second electric push rod.

[0016] The beneficial effects of this utility model are:

[0017] This invention, through the setting of a conveying component and a positioning component, uses the conveying component to continuously transport the bottle body and bottle cap, while the rotating mechanism drives the first electric push rod and vacuum suction cup to achieve multi-angle rotation. Combined with the telescopic function of the electric push rod, the bottle cap can be accurately picked up and adjusted to be directly above the bottle body.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please see Figure 1-3 This utility model provides a technical solution:

[0025] A pressing device for aluminum-plastic bottle caps.

[0026] Includes a base plate 110, on which a pressing assembly for pressing the bottle cap and bottle body is installed, a conveying assembly for conveying the bottle body and bottle cap is installed, a limiting mechanism for fixing the bottle body is installed, and a positioning assembly for positioning the bottle body and bottle cap is installed.

[0027] The positioning component is used to accurately determine the position of the bottle body and the cap, ensuring that they are in the correct relative position before pressing. The conveying component is responsible for transporting the bottle body and the cap to the pressing area in an orderly manner, realizing automated material transfer and improving production efficiency. The pressing component uses mechanical pressure to press the cap tightly onto the bottle body, completing the assembly of the aluminum-plastic cap and the bottle body.

[0028] The positioning assembly includes a rotating mechanism, a first electric push rod 420, and a crossbar 430. The rotating mechanism is mounted on the base plate 110. The first electric push rod 420 is mounted on the rotating mechanism. A crossbar 430 is mounted on the output end of the first electric push rod 420. A vacuum suction cup 440 is mounted on one end of the crossbar 430.

[0029] The rotating mechanism drives the first electric push rod 420 to rotate at an angle. The output end of the first electric push rod 420 can extend or shorten to adjust the height of the crossbar 430 and the vacuum suction cup 440. The vacuum suction cup 440 uses the negative pressure generated by the vacuum pump to adsorb the bottle cap. When the vacuum suction cup 440 is tightly attached to the surface of the object, the vacuum pump pumps air to create a negative pressure inside the suction cup, thus firmly adsorbing the object. When it is necessary to press the bottle cap and the bottle body together, the first electric push rod 420 drives the vacuum suction cup 440 to move vertically. Through the coordinated work of the rotating mechanism, the first electric push rod 420, and the vacuum suction cup 440, the positioning component can accurately grasp, move, and place the bottle cap, achieving precise positioning of the bottle cap and the bottle body.

[0030] The rotating mechanism includes a rotating seat 410, which is mounted on the output end of the first electric push rod 420. A rotating rod 413 is rotatably connected to the rotating seat 410, and one end of the rotating rod 413 is mounted on the bottom of the first electric push rod 420.

[0031] By controlling the rotation angle of the rotating rod 413, the rotating rod 413 drives the vacuum suction cup 440 to rotate via the first electric push rod 420. This allows for more precise adjustment of the direction and position of the vacuum suction cup 440, enabling it to accurately adsorb and place bottle caps or bottles, meeting positioning requirements under different postures, and improving the flexibility and accuracy of positioning.

[0032] A motor 411 is installed on one inner wall of the rotating seat 410. A worm gear 412 is installed on the output end of the motor 411. A worm wheel 414 meshes on the worm gear 412. The worm wheel 414 is installed on the rotating rod 413.

[0033] When the motor 411 drives the worm gear 412 to rotate, the meshing of the worm gear 412 and the worm wheel 414 causes the rotating rod 413 to rotate synchronously, thereby achieving precise adjustment of the angle of the vacuum suction cup 440. This allows the bottle cap on the vacuum suction cup 440 to be placed on the bottle body, thus achieving precise positioning of the bottle cap and the bottle body.

[0034] The conveying assembly includes a first conveyor belt 310 for conveying the bottle body and a second conveyor belt 320 for conveying the bottle cap. Both the first conveyor belt 310 and the second conveyor belt 320 are mounted on the base plate 110. The first conveyor belt 310 and the second conveyor belt 320 are respectively provided with limiting mechanisms for limiting the bottle body and the bottle cap.

[0035] The first conveyor belt 310 and the second conveyor belt 320 are used to transport the bottle body and bottle cap. The first conveyor belt 310 is responsible for transporting the bottle body from the feeding end to the pressing area, while the second conveyor belt 320 transports the bottle cap to the corresponding position. Limiting mechanisms installed on the conveyor belts serve to fix and guide the bottle body and bottle cap, preventing them from shifting or falling during transport. For the bottle body, the limiting mechanism ensures it maintains the correct posture and position on the conveyor belt, facilitating subsequent positioning and pressing; for the bottle cap, the limiting mechanism ensures its stability during transport, allowing it to be accurately gripped by the positioning components.

[0036] The limiting mechanism includes two sets of mounting plates 330, both sets of mounting plates 330 are mounted on the first conveyor belt 310, and both sets of mounting plates 330 are equipped with clamping mechanisms for limiting the bottle body.

[0037] Mounting plate 330, serving as the mounting carrier for the clamping mechanism, is fixedly installed on the first conveyor belt 310, providing stable support for the clamping mechanism. The main function of the clamping mechanism is to secure the bottle during transport, preventing it from swaying or shifting on the conveyor belt. When the bottle reaches the designated position, the clamping mechanism activates, using mechanical force to clamp the bottle and firmly fix it to the conveyor belt. The clamping mechanisms on the two sets of mounting plates 330 are symmetrically arranged, clamping the bottle from both sides to ensure the stability and accuracy of the bottle during the pressing process. This design not only accommodates bottles of different sizes but also maintains the bottle's posture during pressing, ensuring the precision and quality of the aluminum-plastic bottle cap pressing.

[0038] The clamping mechanism includes a cylinder 340, which is mounted on a mounting plate 330. The output end of the cylinder 340 passes through the mounting plate 330, and a clamping block 350 is mounted on the output end of the cylinder 340. A guide rod 360 is mounted on the clamping block 350, and the guide rod 360 is slidably connected to the mounting plate 330. The clamping block 350 has an arc-shaped structure.

[0039] Cylinder 340 is the power source for the clamping mechanism. When cylinder 340 receives a control signal, it pushes the piston to move, thereby moving the clamping block 350 connected to the piston. The clamping block 350 has an arc-shaped structure. This design allows it to better conform to the outer surface of the bottle, increasing the contact area with the bottle, distributing the clamping force evenly, avoiding damage to the bottle, and improving clamping stability. Guide rod 360 is mounted on the clamping block 350 and slidably connected to the guide hole on the mounting plate 330. Its function is to guide the movement of the clamping block 350, ensuring that the clamping block 350 moves in a straight line during movement, preventing the clamping block 350 from deviating or tilting, and ensuring the accuracy and reliability of the clamping action.

[0040] The pressing assembly includes a support frame 210, a second electric push rod 220 is mounted on the top of the support frame 210, the output end of the second electric push rod 220 passes through the support frame 210, and a pressure head 230 is mounted on the output end of the second electric push rod 220.

[0041] Once the bottle body and cap are conveyed to the pressing position and positioned, the second electric push rod 220 is activated, driving the pressing head 230 downwards. The pressing head 230 is designed according to the shape and size of the bottle cap and bottle body, and is generally made of a material with moderate hardness and good wear resistance. When the pressing head 230 contacts the bottle cap, as the second electric push rod 220 continues to press down, the pressing head 230 applies pressure to the bottle cap, tightly pressing it onto the bottle body. By controlling the downward stroke and pressure of the second electric push rod 220, the pressing force can be precisely controlled, ensuring a firm and reliable connection between the bottle cap and bottle body, while avoiding damage to the bottle cap or bottle body due to excessive pressure. After pressing is completed, the second electric push rod 220 rises to its original position, awaiting the next pressing operation. This cycle repeats, achieving continuous pressing of the aluminum-plastic bottle cap and bottle body.

[0042] Specifically, the internal electrical connection structures, specific structures, and models of the first electric push rod 420, vacuum suction cup 440, second electric push rod 220, first conveyor belt 310, second conveyor belt 320, cylinder 340, and motor 411 are well known to those skilled in the art and will not be described in detail here. All electrical components appearing in this application are externally connected to a power source during use.

[0043] The circuits, electrical components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The scope of protection of this utility model does not involve any improvement to the software.

[0044] The control method described in this application is automatic control via a controller. The controller's control circuit can be easily implemented by those skilled in the art through simple programming, and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
