Figure 2 As shown, Figure 2 This is a schematic diagram of the existing technology's medicine pack 100 and medicine bundle 200 before binding. When fixing the medicine pack 100 and medicine bundle 200, a cloth strip 102 needs to be attached to the surface of the medicine bundle 200, and then bound with a rope (or thread). The cloth strip 102 is relatively soft and may be warped and uneven before positioning. If the cloth strip 102 is not smoothed before binding and fixing the medicine pack 100 and medicine bundle 200, the product quality will be affected. Therefore, before binding the medicine pack 100 and medicine bundle 200, the cloth strip 102 needs to be smoothed to facilitate adhesion between the cloth strip 102 and the surface of the medicine bundle 200.

Manually smoothing the fabric strip 102 is time-consuming, labor-intensive, and inefficient. For flexible materials such as the fabric strip 102, existing automated equipment struggles to smooth them effectively. Summary of the Invention

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0037] In the description of this invention, it should be understood that the terms "center," "length," "width," "height," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and "side," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0038] In existing technologies, such as Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a medicine pack in the prior art. The medicine pack 100 includes a medicine pack body 101 and a cloth strip 102, with the cloth strip 102 fixed to the medicine pack body 101. See also... Figure 2 As shown, Figure 2This is a schematic diagram of the existing technology's medicine pack 100 and medicine bundle 200 before binding. When fixing the medicine pack 100 and medicine bundle 200, a cloth strip 102 needs to be attached to the surface of the medicine bundle 200, and then bound with a rope (or thread). The cloth strip 102 is relatively soft and may be warped and uneven before positioning. If the cloth strip 102 is not smoothed before binding and fixing the medicine pack 100 and medicine bundle 200, the product quality will be affected. Therefore, before binding the medicine pack 100 and medicine bundle 200, the cloth strip 102 needs to be smoothed to facilitate adhesion between the cloth strip 102 and the surface of the medicine bundle 200. Figure 1 The fabric strip 102 on the main body of the herbal medicine package needs to be smoothed manually before being attached to the surface of the medicine bundle 200. Manually smoothing the fabric strip 102 is time-consuming, labor-intensive, and inefficient. For flexible materials such as the fabric strip 102, existing automated equipment struggles to smooth them effectively.

[0039] To address the aforementioned issues, this invention provides a positioning and smoothing device that eliminates the need for manual positioning of the medicine pack and manual smoothing of the fabric strip, thereby improving work efficiency and ensuring safe and reliable operation. It is primarily used for positioning and smoothing flexible materials.

[0040] The following is combined with Figures 3-7 The technical solution provided by this invention will be described in more detail below.

[0041] Example 1:

[0042] See Figures 3-7 As shown, the positioning and smoothing device provided by the present invention includes a positioning platform 1, a flipping support plate 2, and a smoothing mechanism 3, wherein: the flipping support plate 2 is rotatably connected to the positioning platform 1, and the flipping support plate 2 has a hanging state and an open state. When the flipping support plate 2 is rotated to the open state, the flipping support plate 2 supports the soft part to a horizontal state (e.g., ...). Figure 3 (As shown); The smoothing mechanism 3 is located on the side of the positioning table 1. The smoothing mechanism 3 includes a moving part 31, which can move horizontally against the upper surface of the soft part (cloth belt 102) to smooth the soft part.

[0043] The aforementioned soft component can be a fabric strip 102 on the main body of the medicine package. This fabric strip 102 is used to adhere to the surface of the medicine bundle 200, facilitating subsequent bundling with the medicine bundle 200. Figure 2 As shown. Alternatively, the soft component can also be used for other soft structures that require smoothing. The following section uses a medicine pouch as an example for detailed explanation.

[0044] Combination Figure 4 and Figure 5 In the figure, the flip support plate 2 is in the open state. At this time, the flip support plate 2 is in a horizontal state, which is convenient for supporting the soft parts.

[0045] See Figure 5The flip support plate 2 is rotatably connected to the positioning table 1 via the rotating shaft 21. When in the open state, the medicine bag body 101 is positioned inside the positioning table 1, and the fabric strip 102 is supported by the flip support plate 2, making the fabric strip horizontal. When the flip support plate 2 is in the hanging state, the end of the flip support plate 2 away from the rotating shaft 21 hangs down naturally. Since the fabric strip 102 is also a soft component, the medicine bag body 101 is located inside the positioning table 1, and the fabric strip 102 also hangs down naturally. At this time, the flip support plate 2 rotates around the rotating shaft 21, which can support the fabric strip 102 to a horizontal state, making it easier to perform the next smoothing operation.

[0046] The positioning and smoothing device of the present invention has a medicine bag body 101 fixedly positioned by a positioning platform 1. The flip support plate 2 can support the cloth strip on the drooping medicine bag body into a horizontal state by rotating. The moving part 31 of the smoothing mechanism 3 moves horizontally against the upper surface of the cloth strip, thereby smoothing the cloth strip. The device can realize the positioning of medicine bag feeding and automatic smoothing of cloth strip, without the need for manual positioning of medicine bag or manual smoothing of cloth strip, thus improving work efficiency and ensuring safe and reliable operation.

[0047] As an alternative implementation, see [link to implementation details]. Figures 3-5 As shown, the positioning and smoothing device also includes a first driving device 4 and a fixed base 5, wherein: see Figure 5 A support rod 51 is provided on the fixed base 5, and the positioning platform 1 is fixed on the support rod 51; one end of the first driving device 4 is rotatably connected to the fixed base 5, and the telescopic end of the first driving device 4 is rotatably connected to the flip support plate 2, thereby driving the flip support plate 2 to rotate.

[0048] The aforementioned first driving device 4 can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. When the telescopic end of the first driving device 4 extends or retracts, it can drive the tilting support plate 2 to rotate, thereby putting the tilting support plate 2 in an open state (e.g., Figures 3-5 (as shown) or in a hanging state.

[0049] As an alternative implementation, see [link to implementation details]. Figures 3-5 As shown, the flip support plate 2 is rotatably connected to the opposite sides of the positioning platform 1, and the first driving device 4 is located on the opposite sides of the fixed base 5 and is drivenly connected to the corresponding flip support plate 2. The smoothing mechanism 3 is located on the opposite sides of the positioning platform 1, and there is a gap between the base 61 and the positioning platform 1.

[0050] The above structure can simultaneously support and smooth two fabric strips (soft components), improving work efficiency.

[0051] As an alternative implementation, see [link to implementation details]. Figure 5 As shown, a positioning groove 11 is formed inside the positioning platform 1, which is used to accommodate the component to be fixed.

[0052] The component to be fixed (the medicine pack body) can be directly placed in the positioning groove 11. The side wall of the positioning groove 11 restricts the movement of the medicine pack, thereby positioning the medicine pack body and preventing it from falling off the positioning table 1 when the cloth tape is smoothed.

[0053] As an alternative implementation, see [link to implementation details]. Figure 3 and Figure 4 , Figure 6 As shown, the smoothing mechanism 3 includes a drive assembly, and the moving part 31 includes a pressing block 311 and an extension arm 312. The drive assembly is driven to the extension arm 312 and is used to drive the extension arm 312 to move in the vertical or horizontal direction. The pressing block 311 is fixed to the end of the extension arm 312 away from the drive assembly and is used to adhere to the upper surface of the soft part.

[0054] The pressing block 311 is fixed to the end of the extension arm 312, fits against the upper surface of the fabric tape (soft part), and smooths the fabric tape (soft part) as the extension arm 312 moves horizontally.

[0055] In this embodiment, the extension arm 312 serves to transmit power, and the extension arm 312 drives the pressing block 311 to move.

[0056] The drive assembly can move the extension arm 312 in the vertical and horizontal directions. When the drive assembly moves the extension arm 312 in the vertical direction, it can make the pressing block 311 adhere to or detach from the upper surface of the fabric (soft part). When the drive assembly moves the extension arm 312 in the horizontal direction, it can make the pressing block 311 smooth the fabric (soft part).

[0057] As an alternative implementation, see [link to implementation details]. Figure 7 As shown, the lower surface of the pressing block 311 is an arc-shaped surface, and the bottom of the arc-shaped surface is in contact with the soft component.

[0058] The aforementioned arc-shaped surface structure can prevent the pressing block 311 from damaging the fabric belt and scratching the fabric belt, thus affecting product quality.

[0059] If the pressing block 311 is pressed tightly against the surface of the cloth strip (soft part) to smooth it out, it is easy to damage the cloth strip. Furthermore, the pressing block 311 and the extension arm 312 have difficulty moving horizontally, resulting in an uneven smoothing action, slow movement of the moving part 31, and even damage to the medicine pack.

[0060] Considering the above issues, see Figure 6 and Figure 7As shown, an adapter 33 is fixed to the output end of the drive assembly. One end of the extension arm 312 away from the pressing block 311 is rotatably connected to the adapter 33. Specifically, one end of the extension arm 312 away from the pressing block 311 is rotatably connected to the adapter 33 through a damping shaft 32. A hook 34 is fixed on the adapter 33, and a tension spring 35 is fixed on the extension arm 312. The bottom end of the tension spring 35 is fixedly connected to the hook 34. The tension spring 35 is used to buffer the impact force between the pressing block 311 and the flip support plate 2.

[0061] Furthermore, the tension spring 35 enables the pressing block 311 to achieve a floating and flexible effect when in contact with the workpiece, avoiding excessive friction due to excessive pressure, which could damage the surface of the workpiece (belt).

[0062] The tension spring 35 is vertically arranged and connects the extension arm 312 and the adapter seat 33. When the lower surface of the pressing block 311 contacts the fabric (soft part), the tension spring 35 deforms to a certain extent, so that a certain buffer is formed between the pressing block 311 and the flip support plate 2. This ensures that the pressing block 311 is in close contact with the surface of the fabric (soft part) while reducing the pressure of the pressing block 311 on the fabric, preventing the pressing block 311 from damaging the fabric, and ensuring that the pressing block 311 moves more smoothly and stably.

[0063] As an alternative implementation, see [link to implementation details]. Figure 6 and Figure 7 As shown, the drive assembly includes a second drive device 62 and a third drive device 63, wherein: the second drive device 62 is vertically arranged, and the telescopic end of the second drive device 62 is drivenly connected to the extension arm 312 through the adapter 33, for driving the adapter 33 and the moving part 31 to move vertically; the third drive device 63 is horizontally arranged, and the telescopic end of the third drive device 63 is fixedly connected to the second drive device 62 through the connecting plate, for driving the second drive device 62 and the moving part 31 to move horizontally.

[0064] The second drive device 62 and the third drive device 63 can be telescopic cylinders, electric cylinders, or hydraulic cylinders, etc. The second drive device 62 can drive the adapter 33, the extension arm 312, and the pressing block 311 to move vertically in sync, so as to achieve the contact between the pressing block 311 and the surface of the fabric (soft part). The third drive device 63 can drive the second drive device 62, the adapter 33, the extension arm 312, and the pressing block 311 to move horizontally in sync, so as to ensure that the pressing block 311 can smoothly perform the smoothing action.

[0065] As an alternative implementation, see [link to implementation details]. Figure 3 and Figure 6As shown, the drive assembly also includes a fourth drive device 64, which is horizontally arranged and fixed on the base 61. The telescopic end of the fourth drive device 64 is arranged opposite to the telescopic end of the third drive device 63. A sliding seat 65 is fixed to the telescopic end of the fourth drive device 64, and the third drive device 63 is fixed on the sliding seat 65. A horizontal guide part 66 is fixed on the base 61, and the sliding seat 65 is slidably connected to the horizontal guide part 66.

[0066] The fourth driving device 64 can be a telescopic cylinder, electric cylinder, or hydraulic cylinder, etc. Without the fourth driving device 64, the third driving device 63 can also achieve horizontal movement of the moving part 31, but the structural stability is relatively poor. In this embodiment, the fourth driving device 64 achieves the overall movement of the sliding seat 65, the third driving device 63, the second driving device 62, and the moving part 31 through telescopic movement, and is horizontally guided by the horizontal guide part 66, ensuring structural stability. After the smoothing action is completed, the telescopic end of the fourth driving device 64 extends, driving the pressing block 311 to disengage from the flipping support plate 2, that is, the pressing block 311 disengages from the fabric belt, facilitating the next step of the operation on the medicine pack.

[0067] See Figure 6 As shown, the horizontal guide part 66 includes a horizontal guide post, a sliding seat 65 is slidably connected to the horizontal guide post, and the horizontal guide post is rotatably connected to the seat body 61 through a bearing seat 67.

[0068] The positioning and smoothing device in this embodiment operates as follows during positioning and smoothing:

[0069] In the initial state, the flip support plate 2 is in a hanging state, and the end of the flip support plate 2 away from the rotating shaft 21 hangs down naturally. The medicine bag is located in the positioning table 1, and the cloth belt also hangs down naturally. The telescopic end of the first driving device 4 extends out and drives the flip support plate 2 to rotate around the rotating shaft 21 as the axis, so that the flip support plate 2 is in an open state, supporting the cloth belt to a horizontal state, which is convenient for the next smoothing operation.

[0070] The third drive device 63 drives the extension arm 312 to move to the smoothing start end of the fabric belt. The telescopic end of the second drive device 62 retracts, driving the adapter 33, extension arm 312 and pressing block 311 to descend. The tension spring 35 deforms, and the pressing block 311 adheres to the upper surface of the fabric belt. The telescopic end of the third drive device 63 retracts, and the pressing block 311 moves horizontally to smooth the fabric belt.

[0071] The smoothing action structure, the fourth drive device 64 drives the third drive device 63, the second drive device 62 and the moving part 31 to move as a whole, thereby driving the pressing block 311 to disengage from the flip support plate 2, that is, the pressing block 311 disengages from the cloth belt, so as to facilitate the next operation process of the medicine pack.
