Description

Technical Field

[0001] This utility model relates to the field of capping machine technology, and more specifically to a capping head cap-removing mechanism for a capping machine. Background Technology

[0002] Pesticide bottles are containers used to hold pesticides, and are generally made of glass or plastic. Traditionally, in the production of bottled pesticides, operators wearing gloves would manually cap the bottles. This method was time-consuming, labor-intensive, and inefficient, and also posed a safety risk of accidental pesticide spillage. With technological advancements, current pesticide bottle manufacturers utilize capping machines for automated capping, significantly improving production efficiency. These machines require the capping head to first use a cap-removing mechanism to pick up the cap before proceeding with the subsequent steps.

[0003] Currently, capping machines generally use vacuum adsorption to remove caps. For example, a gripping capping head mechanism with prior art publication number CN209835579U has the advantages of convenient cap gripping, improved work efficiency, low manufacturing cost, and avoidance of wasted manpower, thus effectively solving the problems and shortcomings of existing devices.

[0004] However, the above-mentioned existing technology still has the following problems when in use: During long-term operation, due to component wear, fatigue and environmental factors, the aging of the vacuum adsorption sealing component will lead to insufficient vacuum, which will affect the adsorption effect of the bottle cap and cause the bottle cap to fall off during the transfer process, thereby reducing the working efficiency of the capping machine. Based on this, the present invention provides a capping head capping mechanism for capping machines with high capping firmness. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a capping head cap-removing mechanism for a capping machine. By setting multiple cap-removing clamps driven by a drive assembly on the mounting plate for mechanical cap removal, and multiple vacuum suction cups working together for cap removal, the combination of these two methods greatly improves the stability of pesticide bottle caps during the clamping and transfer process, preventing caps from falling off and affecting the capping efficiency of the capping head of the capping machine, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a capping head cap-removing mechanism for a capping machine, comprising a mounting plate, a receiving cavity at the center of the mounting plate, at least one movable groove communicating with the receiving cavity at the bottom of the mounting plate, a cap-removing clamping plate in each movable groove, multiple cap-removing clamping plates connected by a driving assembly, at least one vacuum suction cup fixedly embedded at the bottom of the mounting plate, multiple vacuum suction cups connected by the same vacuum assembly, the driving assembly including a number of lead screws the same as the number of movable grooves, a nut block threaded onto the lead screw, the bottom end of the nut block being detachably connected to the top end of the cap-removing clamping plate, and the mounting plate being mounted on the capping head of the capping machine via a connecting assembly.

[0007] In a preferred embodiment, a servo motor is fixedly mounted on the top of the mounting plate, and a rotating rod is fixedly mounted on the bottom of the output shaft of the servo motor. The bottom of the rotating rod passes through the mounting plate and extends into the storage cavity. The rotating rod is connected to multiple lead screws through a gear transmission assembly, which enables multiple lead screws to rotate simultaneously.

[0008] In a preferred embodiment, the connecting assembly includes a hollow tube, the bottom end of which is detachably connected to the top end of the mounting plate, and the hollow tube is sleeved on the outside of the servo motor. At least one heat dissipation hole is provided on the outer wall of the hollow tube to facilitate heat dissipation of the servo motor.

[0009] In a preferred embodiment, an electric push rod is detachably connected to the top of the hollow tube, and a fixing plate is fixedly sleeved on the top of the electric push rod for connecting the electric push rod and the capping machine.

[0010] In a preferred embodiment, the vacuum assembly includes a vacuum pump, which is connected to multiple vacuum suction cups via multiple hoses. The vacuum pump can draw a vacuum into the vacuum suction cups, thereby increasing the adsorption force on the pesticide bottle cap and thus improving the stability of the pesticide bottle cap during the transfer process.

[0011] In a preferred embodiment, each cap-removing clamp is provided with multiple anti-slip strips on its inner wall to increase the friction of the cap-removing clamp surface, thereby improving the stability of the pesticide bottle cap between the multiple cap-removing clamps.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model uses multiple cap-removing clamps driven by a drive assembly on the mounting plate for mechanical cap removal, and multiple vacuum suction cups to cooperate in cap removal. The combination of these two methods greatly improves the stability of pesticide bottle caps during the clamping and transfer process, so as to prevent the caps from falling off and affecting the cap removal efficiency of the capping machine's capping head.

[0014] 2. By installing an electric push rod and a hollow tube between the fixed plate and the mounting plate, the height of the mounting plate can be adjusted using the electric push rod, while the hollow tube covers the servo motor to prevent workers from accidentally touching and getting injured.

[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] Refer to the instruction manual appendix Figure 1-5This utility model provides a capping head cap-removing mechanism for a capping machine, including a mounting plate 1. The mounting plate 1 is mounted on the capping head of the capping machine via a connecting assembly 8. A storage cavity 2 is provided at the center of the mounting plate 1. At least one movable groove 3 communicating with the storage cavity 2 is provided at the bottom of the mounting plate 1. Each movable groove 3 is provided with a cap-removing clamp 4, and multiple anti-slip strips 9 are fixedly provided on the inner wall of each cap-removing clamp 4 to improve the friction of the surface of the cap-removing clamp 4.

[0026] Next, at least one vacuum suction cup 6 is fixedly embedded at the bottom of the mounting plate 1, and the same vacuum component 7 is connected between the multiple vacuum suction cups 6. Specifically, the vacuum component 7 includes a vacuum pump 701. Specifically, the vacuum pump 701 is a device for creating and maintaining an environment below atmospheric pressure in a specific space. The vacuum pump 701 is connected to the multiple vacuum suction cups 6 through multiple hoses respectively.

[0027] Multiple cap-removing clamps 4 are connected by a drive assembly 5. The drive assembly 5 includes a number of lead screws 501 equal to the number of moving slots 3. Nut blocks 502 are threaded onto the lead screws 501. The bottom end of the nut blocks 502 is detachably connected to the top end of the cap-removing clamps 4.

[0028] A servo motor 503 is fixedly mounted on the top of the mounting plate 1. Specifically, the servo motor 503 is a motor that can precisely control position, speed and torque. It is mainly composed of a motor body, encoder, driver and other parts. A rotating rod 504 is fixedly mounted on the bottom of the output shaft of the servo motor 503. The bottom of the rotating rod 504 passes through the mounting plate 1 and extends into the storage cavity 2. The rotating rod 504 is connected to multiple lead screws 501 through a gear transmission assembly 505.

[0029] In use, the operator first installs the connecting component 8 onto the capping machine. Then, the robotic arm on the capping machine can be used to move the mounting plate 1 to remove the cap. Specifically, when the mounting plate 1 moves to the pesticide bottle cap, the vacuum pump 701 is turned on to generate suction force from the vacuum suction cup 6, which holds the top of the pesticide bottle cap. Then, the servo motor 503 drives the rotating rod 504 to rotate. The rotating rod 504 drives multiple lead screws 501 to rotate together through the gear transmission component 505. The nut block 502 on the lead screw 501 moves in the moving groove 3 while driving the cap-removing clamping plate 4 to move, so that the three cap-removing clamping plates 4 approach and clamp the pesticide bottle cap, thus providing secondary reinforcement to the pesticide bottle cap to prevent it from falling off during the transfer process and affecting the capping efficiency of the capping machine's capping head. The operator can also loosen the bolts between the nut block 502 and the cap-removing clamping plate 4, remove the cap-removing clamping plate 4, and then replace it with other types of cap-removing clamping plates 4 for use, thereby improving the practicality of this utility model.

[0030] Refer to the instruction manual appendix Figure 1-5The connecting component 8 includes a hollow tube 801, the bottom end of which is detachably connected to the top end of the mounting plate 1, and the hollow tube 801 is sleeved on the outside of the servo motor 503. At least one heat dissipation hole 802 is provided on the outer wall of the hollow tube 801. An electric push rod 803 is detachably connected to the top end of the hollow tube 801. Specifically, the electric push rod 803 is a device that converts the rotational motion of the motor into the linear motion of the push rod. A fixing plate 804 is fixedly sleeved on the top of the electric push rod 803 for connecting the electric push rod 803 and the capping machine.

[0031] By installing an electric push rod 803 and a hollow tube 801 between the fixed plate 804 and the mounting plate 1, the height of the mounting plate 1 can be adjusted by the electric push rod 803 for better removal of the cover. At the same time, the hollow tube 801 covers the servo motor 503 to prevent workers from accidentally touching and getting injured. In addition, heat dissipation holes 802 are provided on the hollow tube 801 to facilitate heat dissipation of the servo motor 503.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
