Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and more specifically to a split-frame conveyor mechanism. Background Technology

[0002] The guide mechanism is an important component of strapping and packing machines. It is typically used to guide, position, and secure the strapping / packing straps. Its function is to provide a precise path for the packing machine, ensuring that the strapping straps wrap around the item according to the set trajectory. Because the guide mechanism has a cover plate (usually with an overall cross-section in the shape of a U), the strapping straps move within the guide mechanism. During packing, the guide mechanism needs to move back and forth to expose the strapping straps so that they can be tied to the item.

[0003] However, existing conveyor mechanisms are usually designed and assembled with the cover plate as a single unit. When users use the strapping machine to pack items, the entire conveyor mechanism may shift, causing the next section of strapping to be suspended in mid-air. When the conveyor mechanism returns to its original position, if the notch is not aligned with the strapping, the strapping may become misaligned or jammed. Furthermore, assembling the conveyor and cover plate as a single unit makes disassembly and assembly more complicated and increases the cost of maintenance in the later stages. Utility Model Content

[0004] To solve the above problems, this utility model provides the following technical solution:

[0005] A split-frame conveyor mechanism includes a packing machine frame, on which a conveyor mechanism is provided. The conveyor mechanism includes a conveyor and a cover plate. The packing strap moves on the upper surface of the conveyor. The conveyor is fixed to the packing machine frame. The cover plate is movably disposed on the packing machine frame. When the cover plate moves away from the conveyor, it exposes the upper surface of the conveyor. The packing machine frame is provided with a drive mechanism for driving the cover plate to move.

[0006] The present invention is further configured such that: the driving mechanism includes a guide assembly and a power assembly; the guide assembly includes a brake frame slidably mounted on the baling machine frame in a vertical direction; the brake frame has an inclined guide groove; the cover plate has a connecting column protruding into the guide groove and slidably connected to the guide groove; the baling machine frame is provided with a guide column; the cover plate is slidably connected to the guide column; when the brake frame moves in a vertical direction, the connecting column moves along the guide groove, thereby driving the cover plate to move along the guide column; the power assembly is connected to the brake frame for driving the brake frame to move.

[0007] The present invention is further configured such that: at least two positioning grooves are provided on the brake frame, the positioning grooves extend vertically, the baling machine frame has a positioning post protruding into the positioning groove and slidably connected to the positioning groove, and the brake frame is slidably connected to the baling machine frame in the vertical direction through the cooperation of the positioning groove and the positioning post.

[0008] The present invention is further configured such that: the power assembly includes a rotating shaft, one end of which is connected to a drive motor for driving its rotation, and the other end is provided with a rotating lever, the rotating lever being perpendicular to the rotating shaft, and a pull lever being hinged to the end of the rotating lever away from the rotating shaft, and the end of the pull lever away from the rotating lever being hinged to a brake frame, the rotating shaft driving the rotating lever to rotate forward or reverse, thereby causing the pull lever to drive the brake frame to move upward or downward.

[0009] The present invention is further configured such that: a cam is provided on the output shaft of the drive motor, and a roller lever perpendicular to the rotation shaft is provided on the rotation shaft; when the drive motor drives the cam to rotate, the cam's protrusion abuts against the roller lever, causing the roller lever to drive the rotation shaft to rotate.

[0010] The present invention is further configured such that: a manual lever is provided on the rotating shaft, and the manual lever is perpendicular to the rotating shaft.

[0011] The present invention is further configured such that: a guide block protrudes from the cover plate, and a through hole is provided on the guide block; the guide block is sleeved on the guide post through the through hole and is slidably connected to the guide post.

[0012] The present invention is further configured such that: the conveyor mechanism is in the shape of a rectangular frame, and the packaging machine frame is provided with at least one guide post at each of the left and right ends of the cover plate, and the left and right ends of the cover plate are slidably connected to the guide posts respectively.

[0013] The present invention is further configured such that the four inner corners of the conveyor belt mechanism are all rounded.

[0014] Compared with the prior art, the present invention has at least the following advantages:

[0015] 1. The advantage of this utility model is that it adopts a split conveyor mechanism. During packaging, only the cover plate moves back and forth to make room for the packing strap to tighten and complete the packaging. The conveyor remains fixed and always provides support for the packing strap. Compared with the original integrated conveyor mechanism, it can avoid the problems of packing strap misalignment and jamming, increase the stability of equipment operation, save maintenance costs, and improve work efficiency.

[0016] 2. The brake frame is driven up and down by the power component, so that the connecting column on the cover plate moves along the inclined guide groove. Then, through the limiting action of the guide column, the cover plate can only move back and forth in the horizontal direction, that is, move away from or closer to the belt track.

[0017] 3. Guide posts are connected to both ends of the cover plate to keep the overall balance when the cover plate moves back and forth and to avoid tilting to the left or right; by setting the rounded corners of the inner side of the belt channel, the packing strap passes through more smoothly, which can reduce the jamming and tangling and improve the packing efficiency.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] A split-frame conveyor mechanism, such as Figure 1 and Figure 2 As shown, the device includes a strapping machine frame 1, on which a conveyor mechanism is provided. The strapping strap is conveyed within the conveyor mechanism 2 to form a closed loop. The conveyor mechanism includes a conveyor 2 and a cover plate 3. The strapping strap moves on the upper surface of the conveyor 2, and the cover plate 3 covers the top of the strapping strap to prevent it from being exposed.

[0028] The conveyor belt 2 is fixed to the strapping machine frame 1 with screws, while the cover plate 3 is movably mounted on the strapping machine frame 1. The cover plate 3 can move in the back-and-forth direction. When the cover plate 3 moves away from the conveyor belt 2 (i.e., moves forward), the upper surface of the conveyor belt 2 is exposed, allowing space for the strapping to tighten and complete the strapping. After strapping is completed, the cover plate 3 moves back towards the conveyor belt 2 to reset (i.e., moves backward), covering the conveyor belt 2 again. The strapping machine frame 1 is also equipped with a drive mechanism for moving the cover plate 3.

[0029] like Figure 3 and Figure 4 As shown, the drive mechanism includes a guide assembly 4 and a power assembly 5. The power assembly 5 provides power, and the guide assembly 4 guides the cover plate 3 to move horizontally in the front-to-back direction. The guide assembly 4 includes a brake frame 401 slidably disposed within the baling machine frame 1 in the vertical direction. The brake frame 401 has an inclined guide groove 402, which is inclined from top to bottom and rearward. The cover plate 3 has a connecting post 403 protruding into the guide groove 402 and slidably connected to the guide groove 402. Preferably, there are two guide grooves 402, and the upper and lower ends of the side wall of the cover plate 3 are respectively provided with connecting posts 403 to prevent the cover plate 3 from rotating and to improve stability. The baling machine frame 1 is provided with a guide post 404, which extends in the front-to-back direction, and the cover plate 3 is slidably connected to the guide post 404. When the brake frame 401 moves vertically, the connecting column 403 moves along the guide groove 402. Under the limiting and guiding action of the guide column 404, the cover plate 3 is driven to move horizontally back and forth along the guide column 404. The connecting column 403 is cylindrical, and its peripheral wall fits into the guide groove 402. The guide column 404 is cylindrical, and its peripheral wall fits into the cover plate 3. The power assembly 5 is connected to the brake frame 401 to drive the brake frame 401 to move up and down.

[0030] The brake frame 401 has at least two positioning slots 6 extending vertically. A positioning post 7 protrudes from the baling machine frame 1 into the positioning slot 6 and is slidably connected to it. The brake frame 401 is slidably connected to the baling machine frame 1 vertically through the cooperation of the positioning slots 6 and the positioning post 7. The positioning post 7 is cylindrical, and its peripheral sidewall fits against the positioning slot 6.

[0031] like Figure 1 and Figure 5As shown, the power assembly 5 includes a rotating shaft 501, which is rotatably connected to the bracket of the packing machine frame 1. One end of the rotating shaft 501 is connected to a drive motor 502 for driving its rotation, and the other end is fixed with a rotating lever 503. The rotating lever 503 is perpendicular to the rotating shaft 501 and rotates synchronously with the rotating shaft 501. A pull lever 504 is hinged to the end of the rotating lever 503 away from the rotating shaft 501. The end of the pull lever 504 away from the rotating lever 503 is hinged to the brake frame 401. The rotating shaft 501 drives the rotating lever 503 to rotate forward or backward, so that the pull lever 504 drives the brake frame 401 to move upward or downward.

[0032] A cam 505 is provided on the output shaft of the drive motor 502, and a roller lever 506 perpendicular to the rotating shaft 501 is provided on the rotating shaft 501. The roller lever 506 rotates synchronously with the rotating shaft 501. When the drive motor 502 drives the cam 505 to rotate, the protrusion of the cam 505 abuts against the roller lever 506, causing the roller lever 506 to rotate downward or upward, thereby causing the roller lever 506 to drive the rotating shaft 501 to rotate, so that the power component 5 provides power to the brake frame 401.

[0033] A manual lever 9 is also provided on the rotating shaft 501. The manual lever 9 is perpendicular to the rotating shaft 501. The manual lever 9 is used to facilitate the user to manually rotate the rotating shaft 501 when debugging and maintaining the equipment.

[0034] like Figure 1 and Figure 2 As shown, a guide block 8 protrudes from the cover plate 3. A through hole is provided on the guide block 8. The guide block 8 is sleeved on the guide post 404 through the through hole and is slidably connected to the guide post 404, so as to realize the sliding connection between the cover plate 3 and the guide post 404. The peripheral sidewall of the guide post 404 fits against the through hole of the guide block 8.

[0035] The conveyor belt 2 mechanism is rectangular. At least one guide post 404 is provided at each of the left and right ends of the cover plate 3, allowing the left and right ends of the cover plate 3 to slide and connect with the guide posts 404 respectively. This ensures that the cover plate 3 remains balanced when moving back and forth, preventing lateral tilting. Specifically, in this embodiment, guide posts 404 are provided below the left and right ends of the cover plate 3, and guide blocks 8 protrude from the bottom of the left and right ends of the cover plate 3 to cooperate with the guide posts 404.

[0036] In this embodiment, the four inner corners of the conveyor belt mechanism are all rounded, which makes the packing strap pass through more smoothly, reduces jamming and tangling, and improves packing efficiency.

[0037] The working process of this utility model is as follows:

[0038] The user places the item on the packaging machine frame 1. The drive motor 502 drives the roller lever 506 to rotate via the cam 505. The roller lever 506 drives the rotating shaft 501 to rotate. The rotating shaft 501 then drives the pull lever 504 to move downward via the rotating lever 503. The pull lever 504 pulls the brake frame 401 downward, causing the connecting column 403 to slide along the guide groove 402. With the cooperation of the connecting column 403 and the guide column 404, the cover plate 3 moves away from the belt channel 2, thereby deviating from the belt channel 2 to expose the packaging strap, giving the packaging strap space to tighten and complete the packaging. After packaging is completed, the power unit 5 drives the brake frame 401 to move downward, causing the cover plate 3 to reset and wait for the next packaging.

[0039] 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 design concept of the present utility model should be included within the protection scope of the present utility model.
