Description

Technical Field

[0001] This utility model relates to the field of powder packaging technology, specifically to a height adjustment device for bagged powder. Background Technology

[0002] After the powder is packaged, it usually needs to be moved from the loading area to the ground. Since there is a certain height difference between the loading area and the ground, the handling is quite laborious. Existing technology has developed a solution that can adjust the height of the bagged powder, as follows:

[0003] For example, the patent with authorization announcement number CN220263390U, entitled "A Height Adjustment Device for Powder Packaging Bags," includes a lifting mechanism and a conveying mechanism. The lifting mechanism includes a base plate, a support plate, a driving component, a screw-slider mechanism, and a slide rail. The support plate is vertically fixed on the base plate. The screw of the screw-slider mechanism is rotatably mounted vertically on the support plate. The slider of the screw-slider mechanism has a threaded hole, which is screwed onto the screw. The end of the slider away from the screw is mounted on the support plate via the slide rail. The driving component is mounted on the support plate and is used to drive the screw to rotate. The conveying mechanism is fixed on the slider and is used to convey the packaging bag. Although this solution can adjust the height of the packaged powder and lower the bagged powder, the conveying mechanism has a large span and is only connected to the slider on one side. Therefore, the force is unbalanced. Under the action of their own weight, the conveying mechanism and the powder bag will tend to tilt or twist, which can easily cause twisting and breakage at the connection between the conveying mechanism and the slider, thus creating a safety hazard.

[0004] Therefore, the technical problem that this application needs to solve is: how to avoid distortion of the transmission mechanism. Utility Model Content

Detailed Implementation

[0030] The technical solutions of this application will be further described below with reference to specific embodiments, but this application is not limited to these embodiments.

[0031] Example 1

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment proposes a height adjustment device for bagged powder, including a lifting mechanism 11, a conveying mechanism 12, and a base plate 13. The lifting mechanism 11 is mounted on the base plate 13, and the conveying mechanism 12 is mounted on the lifting mechanism 11. It also includes a guide assembly, the upper end of which is mounted on the lower end of the conveying mechanism 12. The guide assembly includes:

[0033] Connecting plate 14, which is fixed to the lower end of the conveying mechanism 12;

[0034] A linkage mechanism is provided between the connecting plate 14 and the base plate 13. The linkage mechanism is used to keep the connecting plate 14 horizontal.

[0035] The linkage mechanism in this solution can ensure that the connecting plate 14 is always in a horizontal state, thereby ensuring that the transmission mechanism 12 is in a horizontal state, effectively avoiding the twisting of the transmission mechanism 12 caused by asymmetrical installation.

[0036] The lifting mechanism 11 and the conveying mechanism 12 are existing technologies in this field. The lifting mechanism 11 can be a vertically arranged lifting cylinder, in which case the conveying mechanism 12 is installed on top of the lifting cylinder. The lifting mechanism 11 can also be a rodless cylinder or a linear motor, or it can be a motor-driven lead screw slider solution from the prior art. In these mechanisms, there is a moving block that moves in the vertical direction, and the moving block is fixedly connected to the conveying mechanism 12.

[0037] The conveying mechanism 12 can be a roller 30 type conveying device as in the prior art. This device has a frame 29 in which rollers 30 are rotatably mounted to facilitate pushing the powder bag on the conveying mechanism 12. Alternatively, the conveying mechanism 12 can also be a conveyor belt as in the prior art, which can realize the mechanized transfer of powder bags.

[0038] Furthermore, each of the linkage mechanisms includes:

[0039] The first connecting arm 15, the two first connecting arms 15 are arranged in parallel, and the upper ends of the two first connecting arms 15 are respectively mounted on the connecting plate 14 through the first rotating mounting seat 16;

[0040] The second connecting arm 17 is horizontally arranged, and its two ends are rotatably connected to the first connecting arm 15 respectively.

[0041] The two third connecting arms 18 are arranged in parallel, and the lower ends of the two third connecting arms 18 are respectively mounted on the base plate 13 through the second rotating mounting seat 19.

[0042] Furthermore, the first connecting arm 15 and the third connecting arm 18 have the same length, and the first connecting arm 15 and the third connecting arm 18 are arranged in a V-shape.

[0043] The guide component in this solution utilizes the parallelogram principle. The two first connecting arms 15, the second connecting arm 17, and the connecting plate 14 form a parallelogram structure. It can be determined that the second connecting arm 17 and the connecting plate 14 are always parallel.

[0044] The two third connecting arms 18, the second connecting arm 17, and the base plate 13 form a parallelogram structure, ensuring that the second connecting arm 17 and the base plate 13 are parallel. Since the second connecting arm 17 and the connecting plate 14 are always parallel, the connecting plate 14 and the base plate 13 are always parallel. This prevents the conveying mechanism 12 on the connecting plate 14 from twisting, thereby offsetting all the torque generated by the conveying mechanism 12 due to its own weight, and thus improving the service life of the entire device.

[0045] Furthermore, to improve the stability of the guiding assembly, a synchronizing rod 31 is installed between the two connecting mechanisms. One end of the synchronizing rod 31 is rotatably mounted on the first connecting arm 15 of one connecting mechanism, and the other end of the synchronizing rod 31 is rotatably mounted on the first connecting arm 15 of the other connecting mechanism. There are two synchronizing rods 31, and they are parallel to each other.

[0046] Example 2

[0047] like Figure 3 As shown, this embodiment modifies the structure and installation method of the guide assembly, using two linkage mechanisms. The structure and installation method of each linkage mechanism are as follows:

[0048] The guiding assembly also includes a first guide rail 20 and a second guide rail 23. The lower end face of the connecting plate 14 is fixed with the first guide rail 20, and the first guide rail 20 is provided with a first slider 21 and a second slider 22.

[0049] The upper end face of the base plate 13 is fixed with a second guide rail 23, and the second guide rail 23 is provided with a third slider 24 and a fourth slider 25.

[0050] The linkage mechanism includes:

[0051] A first hinge arm 26, the upper end of which is rotatably mounted on the first slider 21, and the lower end of which is rotatably mounted on the fourth slider 25.

[0052] The second hinge arm 27 has its upper end rotatably mounted on the second slider 22 and its lower end rotatably mounted on the third slider 24. The first hinge arm 26 and the second hinge arm 27 are rotatably connected at their middle parts.

[0053] This design allows the first hinge arm 26 and the second hinge arm 27 to form an X-structure, effectively ensuring parallelism between the transmission mechanism 12 and the base plate 13. However, this can cause the guide mechanism to slide horizontally. To reduce this sliding, a locking screw 28 is designed, as follows:

[0054] A locking screw 28 is installed on the first slider 21 and / or the second slider 22; when the locking screw 28 is rotated and tightened, the end of the locking screw 28 will press against the first guide rail 20, thereby locking the first slider 21 or the second slider 22.

[0055] When one of the first slider 21 and the second slider 22 is locked, the entire guide mechanism is prevented from moving horizontally. When both the first slider 21 and the second slider 22 are locked simultaneously, the guide mechanism will not move horizontally, and neither the first hinge arm 26 nor the second hinge arm 27 will rotate. When the height of the guide mechanism does not need to be adjusted and it operates at one height for an extended period, the locking screws 28 on the first slider 21 and the second slider 22 can be locked simultaneously.

[0056] Alternatively, locking screws 28 can be installed on the third slider 24 and / or the fourth slider 25. The working principle of the locking screws 28 is similar to that described above, and will not be elaborated further here.

[0057] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
