[0025] This utility model provides a ring-shaped feeding and conveying mechanism for end caps, aiming to solve the problem of low operating efficiency in existing feeding and conveying systems.

[0026] See Figure 1 and Figure 2 This embodiment proposes a ring-shaped feeding and conveying mechanism for end caps, including a ring-shaped material placement component 1, an X-axis conveying component, a Y-axis conveying component, and a gripping component 4. The ring-shaped material placement component 1 includes a base frame 1.1, a ring-shaped moving body 1.2, and multiple material placement seats 1.3. The ring-shaped moving body 1.2 is mounted on the base frame 1.1, and the material placement seats 1.3 are mounted on the ring-shaped moving body 1.2. The material placement seats 1.3 are used to place packaging materials 5. The ring-shaped moving body 1.2 can drive each material placement seat 1.3 to move circumferentially around the center of the base frame 1.1. The Y-axis conveying component is arranged adjacent to the base frame 1.1, and the X-axis conveying component is mounted on the Y-axis conveying component. The Y-axis conveying component can drive the X-axis conveying component to move along the Y-axis direction. The gripping component 4 is mounted on the X-axis conveying component, and the X-axis conveying component can drive the gripping component 4 to move along the X-axis direction. The gripping component 4 can grip the packaging materials 5 on the material placement seats 1.3. In actual operation, each material placement seat 1.3 is used to place different types and specifications of packaging materials 5. The annular moving body 1.2 can move different material placement seats 1.3 to positions corresponding to the gripping component 4. Then, under the action of the Y-axis conveying component, the gripping component 4 is driven to approach the material placement seat 1.3 to grip the packaging materials 5 on the material placement seat 1.3. Then, the X-axis conveying component drives the gripping component 4 to move along the X-axis direction to transport the packaging materials 5 to the docking point of the next process equipment, thereby realizing the automatic feeding and delivery of packaging materials 5 of different specifications and types, effectively improving the work efficiency.

[0027] Among them, see Figure 3 and Figure 4The annular moving body 1.2 includes a material placement drive 1.2.1, sprockets 1.2.2, and a chain 1.2.3. The material placement drive 1.2.1 is mounted on a base frame 1.1. The base frame 1.1 has multiple sprockets 1.2.2 evenly arranged around its circumference. The output shaft of the material placement drive 1.2.1 is connected to one of the sprockets 1.2.2. The chain 1.2.3 meshes with each sprocket 1.2.2 and is connected to each material placement seat 1.3. The material placement seat 1.3 is slidably mounted on the base frame 1.1. The material placement drive 1.2.1 can drive the corresponding sprocket 1.2.2 to rotate, thereby moving the chain 1.2.3 around each sprocket 1.2.2. At the same time, the chain 1.2.3 drives each material placement seat 1.3 to move circumferentially around the center of the base frame 1.1. When it is necessary to grasp packaging materials 5 of different specifications or types, the material placement drive 1.2.1 drives the sprocket 1.2.2 to move the chain 1.2.3 around the sprocket 1.2.2, thereby causing each material placement seat 1.3 connected to the chain 1.2.3 to move circumferentially around the center of the base frame 1.1 until the material placement seat 1.3 corresponding to the packaging material 5 to be grasped moves to the position corresponding to the grasping component 4, at which point the material placement drive 1.2.1 is turned off. This eliminates the need for operators to change the packaging material 5, adapting to different specifications and types of feeding and conveying operations, reducing operational difficulty, and improving feeding and conveying efficiency. Preferably, one sprocket 1.2.2 is correspondingly provided with one material placement drive 1.2.1, and all material placement drives 1.2.1 are driven synchronously.

[0028] Specifically, the annular moving body 1.2 also includes an annular guide rail 1.2.4, a first guide wheel 1.2.5, and a second guide wheel 1.2.6. The annular guide rail 1.2.4 is mounted on the base frame 1.1, and guide grooves A1 are provided on both sides of the annular guide rail 1.2.4. The bottom of the material placement seat 1.3 is provided with two first guide wheels 1.2.5 and two second guide wheels 1.2.6. The two first guide wheels 1.2.5 are symmetrically arranged and are in rolling contact with the guide grooves A1 on the inner side of the annular guide rail 1.2.4. The two second guide wheels 1.2.6 are symmetrically arranged and are in rolling contact with the guide grooves A1 on the outer side of the annular guide rail 1.2.4. The first guide wheels 1.2.5 and the second guide wheels 1.2.6 are arranged in a one-to-one correspondence, and the first guide wheels 1.2.5 and the corresponding second guide wheels 1.2.6 are arranged radially along the center of the annular guide rail 1.2.4. The material placement seat 1.3 can move along the annular guide rail 1.2.4 via the first guide wheel 1.2.5 and the second guide wheel 1.2.6. The first guide wheel 1.2.5 and the second guide wheel 1.2.6 are respectively rolled within the guide grooves A1 on both sides of the annular guide rail 1.2.4 to provide guidance and limit movement. In addition, the first guide wheel 1.2.5 and the corresponding second guide wheel 1.2.6 are arranged radially along the center of the annular guide rail 1.2.4 to ensure that the first guide wheel 1.2.5 on the inner side of the annular guide rail 1.2.4 and the second guide wheel 1.2.6 on the outer side remain synchronized, thereby improving the stability of the material placement seat 1.3 during movement.

[0029] In this example, the annular guide rail 1.2.4 is a circular guide rail. The material placement seat 1.3 can move in a circular motion on the circular guide rail. When the material placement seat 1.3 corresponding to the packaging material 5 moves to be parallel to the vertical plane in the X-axis direction, the material placement seat 1.3 is correspondingly set with the gripping component 4. Then, the X-axis conveying component is driven by the Y-axis conveying component to move closer to the material placement seat 1.3 along the Y-axis direction, so that the gripping component 4 can grip the packaging material 5 on the material placement seat 1.3. When gripping different packaging materials 5, it is only necessary to move the corresponding material placement rack to be parallel to the vertical plane in the X-axis direction under the action of the material placement drive component 1.2.1. The operation is simple and can adapt to the feeding and conveying of different packaging materials 5, which is conducive to improving the work efficiency.

[0030] In another example of this embodiment, the annular guide rail 1.2.4 is a square annular guide rail, with a sprocket 1.2.2 at each of its four corners. One side of the square annular guide rail is parallel to the X-axis beam. When gripping a specific packaged material 5, simply move the corresponding material holder 1.3 to the side of the square annular guide rail parallel to the X-axis beam, and then adjust the position of the gripping component 4 using the X-axis conveying assembly and the Y-axis conveying assembly to grip the packaged material 5 on that side. In actual operation, several commonly used packaged materials 5 can be moved to the side of the square annular guide rail parallel to the X-axis beam to reduce the number of times the material holder 1.3 needs to be moved, thereby shortening the waiting time and further improving work efficiency.

[0031] Furthermore, the annular moving body 1.2 also includes a connecting block 1.2.7, which is disposed on the material placement seat 1.3 and connected to the chain 1.2.3 by fasteners. The material placement seat 1.3 is connected to the chain 1.2.3 via the connecting block 1.2.7 to ensure connection strength and improve the stability of the material placement seat 1.3 during movement.

[0032] Furthermore, the material placement base 1.3 includes a base plate 1.3.1, a vertical plate 1.3.2, a sleeve rod 1.3.3, and a reinforcing plate 1.3.4. The base plate 1.3.1 is slidably mounted on the annular moving body 1.2, and the vertical plate 1.3.2 is vertically mounted on the base plate 1.3.1. The sleeve rod 1.3.3 is vertically connected to the vertical plate 1.3.2 and is used to place the packaging material 5. The reinforcing plate 1.3.4 is connected between the base plate 1.3.1 and the vertical plate 1.3.2. The packaging material 5 has through holes corresponding to the sleeve rod 1.3.3, and the packaging material 5 is fitted onto the sleeve rod 1.3.3 through the through holes. The reinforcing plate 1.3.4, connected between the base plate 1.3.1 and the vertical plate 1.3.2, can effectively improve the structural strength of the material placement base 1.3.

[0033] In this embodiment, the X-axis conveying assembly includes an X-axis beam, an X-axis conveying drive, transmission wheels 2.3, a transmission belt 2.4, and a slider 2.5. The X-axis beam is slidably mounted on the Y-axis conveying assembly; the X-axis conveying drive is mounted on the X-axis beam; vertically mounted transmission wheels 2.3 are provided at both ends of the X-axis beam, and one of the transmission wheels 2.3 is connected to the output shaft of the X-axis conveying drive; the transmission belt 2.4 is wound around the two transmission wheels 2.3; the slider 2.5 is slidably connected to the conveying guide rail, and the slider 2.5 is connected to the lower layer of the transmission belt 2.4; the gripping assembly 4 is mounted on the slider 2.5. The X-axis conveying drive drives the transmission wheels 2.3 to move the transmission belt 2.4 around the two transmission wheels 2.3, thereby moving the slider 2.5 along the X-axis direction, and thus moving the gripping assembly 4. This allows for adjustment of the relative position of the gripping assembly 4 and the annular material placement assembly 1, and also enables the gripping assembly 4 to perform material feeding operations along the X-axis direction.

[0034] In this embodiment, the Y-axis conveying assembly includes a support frame 3.1, a Y-axis crossbeam, and a Y-axis conveying drive. The support frame 3.1 is adjacent to the base frame 1.1, and two spaced-apart Y-axis crossbeams are provided on the support frame 3.1. An X-axis crossbeam is slidably connected to the two Y-axis crossbeams. The Y-axis conveying drive is disposed on the Y-axis crossbeam, and its output end is connected to the X-axis crossbeam. The Y-axis conveying drive can drive the X-axis crossbeam to move along the Y-axis direction. The Y-axis conveying drive includes a motor and a screw. The motor is disposed on the Y-axis crossbeam, and the screw is rotatably disposed on the Y-axis crossbeam along the Y-axis direction. The screw is connected to the output shaft of the motor, and the X-axis crossbeam is threadedly connected to the screw. The motor drives the screw to rotate, thereby moving the X-axis crossbeam along the Y-axis direction. Preferably, one Y-axis conveying drive is provided for each Y-axis crossbeam, and two Y-axis conveying drives work together to improve the stability of the Y-axis movement operation.

[0035] In this embodiment, the gripping component 4 includes an extension rod 4.1 and a gripping body 4.2. The extension rod 4.1 is connected between the slider 2.5 and the gripping body 4.2. The gripping body 4.2 is equipped with a suction cup 4.2.1 for absorbing the packaging material 5. The center of the gripping body 4.2 is at the same height as the sleeve rod 1.3.3 on the material placement seat 1.3. The suction cup 4.2.1 is connected to a vacuum pump, which can control the suction cup 4.2.1 to absorb or release the packaging material 5.
