[0023] This utility model proposes a multi-specification feeding and conveying mechanism for end caps, aiming to solve the problems of existing equipment being unable to adapt to the feeding and conveying of different specifications and types of packaging materials and having low operating efficiency.

[0024] See Figures 1 to 3This embodiment provides a multi-specification feeding and conveying mechanism for end caps, including a material placement base 1, an X-axis moving assembly, a Y-axis moving assembly, a Z-axis moving assembly, a first gripping assembly 5, and a second gripping assembly 6. The material placement base 1 is used to place packaging materials 8. The X-axis moving assembly is disposed on the material placement base 1 along the X-axis direction. The Y-axis moving assembly is disposed on the material placement base 1 along the Y-axis direction. The Z-axis moving assembly is slidably disposed on the Y-axis moving assembly, and the Y-axis moving assembly can drive the Z-axis moving assembly to move along the Y-axis direction. The first gripping assembly 5 is slidably disposed on the Z-axis moving assembly, and the Z-axis moving assembly can drive the first gripping assembly 5 to move along the Z-axis direction. The first gripping assembly 5 can grip the packaging materials 8 on the material placement base 1. The second gripping assembly 6 is slidably disposed on the Y-axis moving assembly, and the Y-axis moving assembly can drive the second gripping assembly 6 to move along the Y-axis direction. The second gripping assembly 6 can grip the packaging materials 8 on the first gripping assembly 5. In actual operation, the first gripping component 5, driven by the Y-axis and Z-axis moving components, grips the packaging material 8 on the placement base 1. It then moves towards the second gripping component 6 via the Y-axis moving component, allowing the second gripping component 6 to grip the packaging material 8 on the first gripping component 5. The X-axis moving component then drives the second gripping component 6 to move along the X-axis to a designated position. The second gripping component 6 of this invention can adjust its relative position on the placement base 1 via the Y-axis moving component, facilitating the gripping of different specifications and types of packaging materials 8 on the placement base 1. Furthermore, the cooperation of the X-axis, Y-axis, and Z-axis moving components, along with the first and second gripping components 5, achieves automatic feeding and delivery of the packaging material 8, effectively improving operational efficiency. In this embodiment, the placement base 1 holds different specifications and types of packaging materials 8, such as different specifications of foam caps and different specifications of cardboard caps.

[0025] The X-axis moving assembly includes an X-axis guide rail, an X-axis drive component, transmission wheels 2.3, a transmission belt, and a slider 2.4. The X-axis guide rail is mounted on the material placement base 1. The X-axis drive component is mounted on the X-axis guide rail. A vertically arranged transmission wheel 2.3 is located at each end of the X-axis guide rail, and one of the transmission wheels 2.3 is connected to the X-axis drive component. The transmission belt is wound around the two transmission wheels 2.3. The slider 2.4 is slidably connected to the X-axis guide rail and is connected to the lower layer of the transmission belt. The second material gripping assembly 6 is mounted on the slider 2.4. The X-axis drive component drives the transmission wheels 2.3 to rotate, and through the transmission belt, drives the other transmission wheel 2.3 to rotate. While the transmission belt rotates around the two transmission wheels 2.3, it simultaneously drives the second material gripping assembly 6 to move along the X-axis direction through the slider 2.4. The slidable connection between the slider 2.4 and the X-axis guide rail serves both as a guide and as a limiter, which helps improve the stability of the second material gripping assembly 6 during movement.

[0026] Specifically, the Y-axis moving assembly includes a Y-axis guide rail, a Y-axis slide, a Y-axis drive, a Y-axis gear, and a Y-axis rack. The Y-axis guide rail is mounted on the material placement base 1. The Y-axis slide is slidably mounted on the Y-axis guide rail, with a gap between the bottom of the Y-axis slide and the Y-axis guide rail. The Y-axis drive is mounted on the Y-axis slide, and the Y-axis gear is positioned within the gap, connected to the output shaft of the Y-axis drive. The Y-axis rack is mounted on the Y-axis guide rail and meshes with the Y-axis gear. The Z-axis moving assembly is mounted on the Y-axis slide. The Y-axis drive drives the Y-axis gear to rotate, thereby causing the Y-axis slide to move on the Y-axis guide rail under the reaction force of the Y-axis rack meshing with the Y-axis gear. This, in turn, causes the Z-axis moving assembly to move, realizing the movement of the first gripping assembly in the Y-axis direction, so as to grip the packaging materials 8 at different positions on the material placement base 1.

[0027] In this embodiment, the Z-axis moving assembly includes a Z-axis mounting base, a Z-axis slide rod, a Z-axis drive, a Z-axis gear, and a Z-axis rack. The Z-axis mounting base is vertically mounted on the Y-axis slide. The Z-axis slide rod is slidably mounted on the Z-axis mounting base in the vertical direction. The Z-axis drive is mounted on the Y-axis slide, and its output shaft is connected to the Z-axis gear. The Z-axis rack is mounted vertically on the Z-axis slide rod, and meshes with the Z-axis gear. A first gripping assembly is located at the lower end of the Z-axis slide rod. The Z-axis drive drives the Z-axis gear to rotate, thereby moving the Z-axis slide rod up and down through the Z-axis rack meshing with the Z-axis gear. This adjusts the height of the first gripping assembly, allowing it to grip packaging materials 8 at different heights and to lift the packaging materials 8 to their highest position before moving them in the Y-axis direction, thus avoiding interference.

[0028] Furthermore, the multi-specification feeding and conveying mechanism for the end caps includes two Z-axis moving components symmetrically arranged on the Y-axis slide, and each Z-axis moving component is correspondingly equipped with a first gripping component. The two first gripping components work together to achieve both alternating gripping of the same packaging material 8 and simultaneous gripping of two different materials, effectively reducing operation waiting time and further improving operation efficiency.

[0029] In this embodiment, the first gripping component includes a rotary seat 5.1, an adapter seat 5.2, and a first gripping body 5.3. The rotary seat 5.1 is mounted on a Z-axis slide bar, and the adapter seat 5.2 is connected to the output shaft of the rotary seat 5.1. The first gripping body 5.3 is vertically connected to the adapter seat 5.2, and the first gripping body 5.3 is equipped with a suction cup 7 for picking up the packaging material 8. The rotary seat 5.1 can drive the first gripping body 5.3 to move between a horizontal and a vertical position via the adapter seat 5.2. After the first gripping body 5.3 grips the packaging material 8 in a horizontal position, the Z-axis moving component drives the first gripping component to rise to its highest position, and then moves it to the corresponding position of the second gripping component via the Y-axis moving component. At this time, the rotary seat 5.1 is activated to drive the first gripping body 5.3 to rotate to a vertical position to facilitate docking with the second gripping body 5.2.

[0030] In this embodiment, the material placement base frame 1 includes a base plate 1.1, a vertical frame 1.2, and material placement sleeves 1.3. The vertical frame 1.2 is located on the center line of the base plate 1.1. The base plate 1.1 is provided with a plurality of evenly arranged material placement sleeves 1.3, and each material placement sleeve 1.3 is symmetrically arranged about the vertical frame 1.2. The first gripping body 5.3 is provided with through holes 5.3.1 that match the material placement sleeves 1.3. The packaging material 8 is provided with through holes 5.3.1 at its center. The packaging material 8 is fitted onto the material placement sleeves 1.3 through the through holes 5.3.1 so that the first gripping component can grip it. Different specifications and models of packaging materials 8 can be placed on each material placement sleeve 1.3 to adapt to the feeding and delivery of packaging materials 8 of different specifications and types.

[0031] In this embodiment, the second gripping mechanism includes an extension rod 6.1 and a second gripping body 6.2. The extension rod 6.1 is connected between the slider 2.4 and the second gripping body 6.2. The second gripping body 6.2 is provided with a suction cup 7 for absorbing the packaging material 8. When the first gripping body 5.3 rises to its highest position, it switches to a vertical position and corresponds to the second gripping body 6.2, thereby facilitating the second gripping body 6.2 to grip the packaging material 8 on the first gripping body 5.3.

[0032] In this embodiment, the suction cups 7 on the first gripping body 5.3 and the second gripping body 6.2 are both connected to a vacuum pump, and the vacuum pump can control the suction cups 7 to suck up or release the packaging material 8.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
