Description

Technical Field

[0001] This utility model relates to a welding nozzle machine, and more particularly to a high-speed, fast-adjustable feeding mechanism for a welding nozzle machine. Background Technology

[0002] A nozzle welding machine is a device that welds nozzles onto plastic bags. The nozzle welding machine needs to pick up plastic bags from the conveyor line and transfer them to the assembly line.

[0003] Therefore, the applicant designed a high-speed feeding mechanism combined with a welding nozzle machine (application number: 2024222911491) to grab plastic bags on the conveyor line and transfer them to the assembly line. The above structure is fast and efficient.

[0004] However, the speed of the feeding mechanism must match the speed of the assembly line to ensure smooth operation of the entire production line. The aforementioned pressure belt conveyor mechanism uses upper and lower belts to clamp the plastic bags and move them together, then transports the plastic bags to the positioning table for positioning. However, after the plastic bags come out of the pressure belt conveyor mechanism, they slide a short distance to the predetermined position on the positioning table due to inertia. Therefore, different materials of the plastic bags, or if they are contaminated with oil or water, will cause the plastic bags to slide at different speeds, resulting in different times when they reach the predetermined position on the positioning table, thus creating a difference with the speed of the assembly line. Therefore, after each change of plastic bag, the speed of the pressure belt conveyor mechanism needs to be adjusted (e.g., the speed of the pressure belt conveyor mechanism can be reduced for smoother materials, and increased for rougher materials) to ensure that the plastic bags reach the predetermined position on the positioning table in a consistent time. However, the adjustment is time-consuming, and frequent adjustments seriously delay production time, greatly increasing production costs for manufacturers of small-batch, multi-specification plastic bags. Moreover, the pressure belt conveyor mechanism is located below the gripper frame, where mechanical parts are densely distributed, making it difficult to adjust the bag positioning mechanism when changing plastic bags of different sizes during production due to the limited space below. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a high-speed, fast-adjustable feeding mechanism for welding nozzles.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] The high-speed, quick-adjustable feeding mechanism for a welding nozzle machine is characterized by comprising a transfer platform, a suction cup gripping mechanism 1 and a suction cup gripping mechanism 2 mounted on a gripping frame. The suction cup gripping mechanism 1 can grip a plastic bag from the feeding position and transport it to the transfer platform, and the suction cup gripping mechanism 2 can grip the plastic bag from the transfer platform to a predetermined position.

[0008] The suction cup gripping mechanism includes a translation drive cylinder, a linear guide rail assembly, a translation frame, a lifting drive cylinder mounted on the translation frame, a suction cup frame mounted on the lifting drive cylinder, and a plurality of suction cup assemblies mounted on the suction cup frame. The translation frame is connected to the linear guide rail assembly and the translation drive cylinder.

[0009] The suction cup gripping mechanism 2 includes a servo motor linear module, a translation plate, a lifting drive mechanism set on the translation plate, a suction cup frame 2 set on the lifting drive mechanism, and a plurality of suction cup components 2 set on the suction cup frame 2. The translation plate is connected to the servo motor linear module.

[0010] The lifting drive mechanism includes a primary lifting cylinder, a lifting plate mounted on the primary lifting cylinder, and a secondary lifting cylinder mounted on the lifting plate. The suction cup frame is connected to the secondary lifting cylinder.

[0011] The lifting plate includes a first plate and a second plate that is perpendicularly connected to the first plate. The first-stage lifting cylinder is connected to the first plate, and the second-stage lifting cylinder is installed on the second plate.

[0012] It also includes a positioning platform and lifting positioning rod one, lifting positioning rod two, positioning push rod one, and positioning push rod two. The lifting positioning rod one and lifting positioning rod two are lifted and lowered by the push of the corresponding lifting positioning cylinder. The positioning push rod one is moved by the push of the positioning push rod cylinder to push the side of the plastic bag. The positioning push rod two is lifted and lowered and pushes the plastic bag by the drive of the cylinder assembly.

[0013] It also includes a screw with a handle. The lifting and positioning cylinder, the positioning push rod cylinder and the cylinder assembly are all set on the adjustment plate. The adjustment plate has an elongated hole. The gripping frame has an adjustment screw hole. The screw with a handle fixes the adjustment plate by cooperating with the adjustment screw hole through the elongated hole.

[0014] The beneficial effects of this utility model are as follows: This utility model includes a transfer platform, a suction cup gripping mechanism 1 and a suction cup gripping mechanism 2 mounted on a gripping frame. The suction cup gripping mechanism 1 can grip plastic bags from the loading position and transport them to the transfer platform, while the suction cup gripping mechanism 2 can grip the plastic bags from the transfer platform to a predetermined position. With the above structure, the suction cup gripping mechanism 1 and the suction cup gripping mechanism 2 can work simultaneously, which not only ensures gripping speed and efficiency, but also ensures that the plastic bags are directly gripped from the transfer platform to the predetermined position by the suction cup gripping mechanism 2 without inertial sliding. Therefore, the gripping speed and time are consistent regardless of the material and specifications of the plastic bags, thus eliminating the need for adjustment and greatly improving gripping efficiency, thereby also improving production efficiency.

[0026] As will be fully understood by those skilled in the art, the features of the different embodiments of this disclosure may be coupled or combined with each other in part or in whole, and may cooperate with each other and be technically driven in various ways. The embodiments of this disclosure may be implemented independently of each other, or may be implemented together in an interdependent relationship.

[0027] Reference Figures 1 to 4 This utility model discloses a high-speed, quick-adjustment feeding mechanism for a welding nozzle machine, including a transfer platform 1, a suction cup gripping mechanism 3 and a suction cup gripping mechanism 4 mounted on a gripping frame 2. The transfer platform 1 is a stainless steel sheet metal part with a U-shaped structure. The suction cup gripping mechanism 3 can grab plastic bags from the feeding position and transport them to the transfer platform 1, and the suction cup gripping mechanism 4 can grab the plastic bags from the transfer platform 1 to a predetermined position.

[0028] In the above structure, suction cup gripping mechanism 3 is responsible for gripping the plastic bag from the conveyor line to the transfer station 1; while suction cup gripping mechanism 4 is responsible for gripping the plastic bag from the transfer station 1 to the positioning station 100. When suction cup gripping mechanism 3 moves from the transfer station 1 to the conveyor line, suction cup gripping mechanism 4 moves from the transfer station 1 to the positioning station 100. The platform 100 moves towards the transfer station 1 to prepare to grab a plastic bag. The suction cup gripping mechanism 1 3 and the suction cup gripping mechanism 2 4 work together to improve the gripping speed and efficiency. Moreover, the plastic bag is directly grabbed from the transfer station 1 to the predetermined position by the suction cup gripping mechanism 2 4 without inertial sliding. Therefore, the gripping speed and time are consistent regardless of the material and specification of the plastic bag, so no adjustment is required, which greatly improves the gripping efficiency and thus improves the production efficiency.

[0029] As shown in the figure, the suction cup gripping mechanism 3 includes a translation drive cylinder 5, a linear guide rail assembly 6, a translation frame 7, a lifting drive cylinder 8 mounted on the translation frame 7, a suction cup frame 9 mounted on the lifting drive cylinder 8, and several suction cup assemblies 10 mounted on the suction cup frame 9. The translation frame 7 is connected to the linear guide rail assembly 6 and the translation drive cylinder 5. The translation drive cylinder 5 drives the translation frame 7 to move linearly, thereby moving it to the conveyor line or the transfer table 1. When gripping, the lifting drive cylinder 8 drives the suction cup frame 9 to descend, causing the suction cups of the suction cup assemblies 10 to come into close contact with the plastic bag and adhere to it. The lifting drive cylinder 8 then drives the suction cup frame 9 to rise, thus conveying the plastic bag.

[0030] As shown in the figure, the suction cup gripping mechanism 2 4 includes a servo motor linear module 11, a translation plate 12, a lifting drive mechanism 13 mounted on the translation plate 12, a suction cup frame 2 14 mounted on the lifting drive mechanism 13, and several suction cup components 2 15 mounted on the suction cup frame 2 14. The translation plate 12 is connected to the servo motor linear module 11, and the servo motor linear module 11 drives the translation plate 12 to move linearly, thereby moving it to the positioning platform 100 or the transfer platform 1. The working principle of suction cup component 2 15 is the same as that of suction cup component 10, and therefore will not be described in detail. The structures of suction cup component 2 15 and suction cup component 10 are also existing technologies, and therefore will not be described in detail.

[0031] In the above structure, the translation drive cylinder 5 of the translation frame 7 can save costs because the speed of the translation drive cylinder 5 is not adjustable. Therefore, the second suction cup gripping mechanism 4 uses a servo motor linear module 11 as the drive. The servo motor linear module 11 can control the moving speed of the translation plate 12, thus achieving a perfect speed connection between the second suction cup gripping mechanism 4 and the first suction cup gripping mechanism 3, and keeping the cost as low as possible. Moreover, both the second suction cup gripping mechanism 4 and the first suction cup gripping mechanism 3 are located in the open space at the top of the gripping frame 2, which is convenient for updates and maintenance.

[0032] As shown in the figure, the lifting drive mechanism 13 includes a primary lifting cylinder 16, a lifting plate 17 mounted on the primary lifting cylinder 16, and a secondary lifting cylinder 18 mounted on the lifting plate 17. The suction cup frame 14 is connected to the secondary lifting cylinder 18. This structure can improve the gripping efficiency because the stroke of the secondary lifting cylinder 18 is relatively short, about 10 millimeters. This means that when the suction cup assembly 15 grips the plastic bag above the positioning platform 100, the descent time of the secondary lifting cylinder 18 is short. However, because the shape of the plastic bag is easily deformed and curls upwards, the 10-millimeter distance between the suction cup assembly 15 and the plastic bag can easily cause interference. Therefore, in the suction cup gripping mechanism 14, the suction cup frame 14 moves towards the transfer platform 1... During movement, the primary lifting cylinder 16 activates, driving the secondary lifting cylinder 18, suction cup frame 2 14, and suction cup assembly 2 15 to rise, increasing the distance between suction cup assembly 2 15 and the plastic bag, further raising the height of suction cup assembly 2 15, and avoiding interference between suction cup assembly 2 15 and the plastic bag. However, after grabbing the plastic bag, the primary lifting cylinder 16 will work during movement to drive the secondary lifting cylinder 18, suction cup frame 2 14, and suction cup assembly 2 15 to descend, thereby minimizing the distance between suction cup assembly 2 15 and the plastic bag. As a result, when moving above the positioning platform 100, the descent time of the secondary lifting cylinder 18 is short. The above structure ensures both smooth grabbing and grabbing efficiency.

[0033] Specifically, the lifting plate 17 includes a first plate and a second plate that is perpendicularly connected to the first plate. The first-stage lifting cylinder 16 is connected to the first plate, and the second-stage lifting cylinder 18 is installed on the second plate.

[0034] As shown in the figure, the system also includes a positioning platform 100, a lifting positioning rod 19, a lifting positioning rod 20, a positioning push rod 1 21, and a positioning push rod 22. The lifting positioning rods 19 and 20 are raised and lowered by the corresponding lifting positioning cylinders 23. The positioning push rod 21 is moved by the positioning push rod cylinder 24, thus pushing the side of the plastic bag. The positioning push rod 22 is raised and lowered by the cylinder assembly 28, and also pushes the plastic bag. With this structure, when the plastic bag... After being placed on the positioning platform 100, lifting positioning rod 19 and lifting positioning rod 20 are located on adjacent sides of the plastic bag, and positioning push rod 11 and positioning push rod 22 are located on the other adjacent sides of the plastic bag. Lifting positioning rod 19 and lifting positioning rod 20 rise, and then positioning push rod 22 also rises. Then positioning push rod 11 and positioning push rod 22 move to push the plastic bag toward lifting positioning rod 19 and lifting positioning rod 20, thereby positioning it and waiting for the clamping structure to clamp it onto the assembly line. The cylinder assembly 28 includes two cylinders, one horizontally arranged to push positioning push rod 22 to move, and the other vertically arranged to raise positioning push rod 22.

[0035] As shown in the figure, it also includes a screw rod 25 with a handle. The lifting and positioning cylinder 23, the positioning push rod cylinder 24, and the cylinder assembly 28 are all mounted on the adjusting plate 26. The adjusting plate 26 has an elongated hole 27, and the gripping frame 2 has an adjusting screw hole. The screw rod 25 with a handle fixes the adjusting plate 26 by engaging with the adjusting screw hole through the elongated hole 27. The position of the lifting and positioning cylinder 23, the positioning push rod cylinder 24, and the cylinder assembly 28 can be easily adjusted by the screw rod 25 with a handle.

Specific examples have been used to illustrate the principle and implementation of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
