Description

Technical Field

[0001] This utility model belongs to the field of packaging technology, specifically referring to a guiding device for packaging bags of Tibetan medicine external powder. Background Technology

[0002] In the packaging process of powdered Tibetan medicines, the packaging bag is usually folded in half and clamped tightly before the powder is poured into the bag. After heat pressing and cutting, it is formed into an individual package. However, in actual operation, the folding process of the packaging bag is prone to premature folding or deformation such as bending and bulging in the feeding direction, which seriously affects the quality of subsequent filling and sealing.

[0003] These problems mainly stem from a lack of effective guidance and control during the folding process and insufficient bag tension. Therefore, to ensure continuous and stable packaging operations, it is essential to correctly guide the folding trajectory of the packaging bag and maintain appropriate tension throughout the transport process, thereby avoiding the adverse effects of abnormal shapes on overall packaging efficiency and finished product quality. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a guiding device for packaging bags of Tibetan medicine external powder, which at least partially solves the above problems.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes a guiding device for packaging bags of Tibetan medicine external powder, comprising: The material rollers mounted on the support are used to secure the packaging bag rolls. An inner support arc-shaped tube is fixed below the material roller and configured with an arc-shaped opening facing the direction of powder feeding. The outer hoop frame includes a U-shaped clamp and an outer hoop arc plate. The outer hoop arc plate is located below the inner support arc tube and is also configured with an arc-shaped opening facing the direction of powder feeding. The U-shaped clamp is located below the outer hoop arc plate and protrudes outward from the outer hoop arc plate. The radius of the inner supporting arc tube is greater than the radius of the outer hoop arc plate. The projections of the inner supporting arc tube and the outer hoop arc plate on the horizontal plane intersect, and there is a gap between the far ends of their arcs. The opening gap of the U-shaped clamp is smaller than the chord length of the outer hoop arc plate.

[0006] Furthermore, the centers of the inner supporting arc-shaped tube and the outer hoop arc-shaped plate are in the same vertical plane.

[0007] Furthermore, the support is provided with a guide roller, which is connected to the support through an elastic element to adjust the tension of the packaging bag, and the guide roller is configured to be rotatable.

[0008] Furthermore, the lower end of the outer frame is provided with a heat clamping plate, which is symmetrically arranged on both sides of the packaging bag and can slide relative to each other. Below the heat clamping plate are rollers, which are symmetrically arranged on both sides of the packaging bag.

[0009] Furthermore, the lower end of the outer hoop is symmetrically provided with a fixing plate, and the hot clamping plate includes a first support plate, a second support plate and a sliding rod. The sliding rod is slidably disposed in the fixing plate. The first support plate is disposed at the outer end of the sliding rod, and the second support plate is disposed at the inner end of the sliding rod. The fixing plate is provided with a first cylinder, and the telescopic end of the first cylinder is connected to the first support plate.

[0010] The beneficial effects of this utility model are as follows: the inner support arc tube can provide support from the inside of the packaging bag, effectively preventing the packaging bag from bending or collapsing inward; the outer hoop fixes the packaging bag from the outside. The two work together to achieve stable constraint on the inner and outer sides of the packaging bag, thereby effectively avoiding deformation such as bulging and bending; in addition, the outer hoop arc plate and U-shaped clamp of the outer hoop adopt an inclined closing design, which can guide the packaging bag to smoothly transition from the open state to the folded state, creating favorable conditions for subsequent powder filling.

[0013] The accompanying drawings are provided to further understand the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation thereof. Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0016] like Figures 1-4 As shown in the embodiment of this utility model, a guiding device for packaging bags of Tibetan medicine external application powder includes a workbench 1, a support 2, and a material roller 3. The support 2 is fixed on the workbench 1, and the material roller 3 is disposed on the support 2 for fixing the material roll of the packaging bag. An inner support arc-shaped tube 6 is provided below the material roller 3. The inner support arc-shaped tube 6 is installed on the side wall of the workbench 1 and is configured with an arc-shaped opening facing the direction of powder feeding, so that the flat packaging table is initially bent into an arc shape. An outer hoop 7 is provided below the inner support arc-shaped tube 6 and is fixed on the workbench 1. The outer hoop 7 includes a U-shaped clamp 18 and an outer hoop arc-shaped plate 19. The outer hoop arc-shaped plate 19 is disposed below the inner support arc-shaped tube 6 and is also configured with an arc-shaped opening facing the direction of powder feeding. The U-shaped clamp 18 is disposed below the outer hoop arc-shaped plate 19 and protrudes obliquely outward toward the outer side of the outer hoop arc-shaped plate 19.

[0017] Specifically, after the packaging bag on the material roller 3 is laid out flat, it will pass through the inner support arc tube 6, the outer hoop arc plate 19 and the U-shaped clamp 18 in sequence. The inner support arc tube 6 can provide support from the inside of the packaging bag to prevent the packaging bag from bending or collapsing inward. The packaging bag continues to pass downward, while the outer hoop 7 fixes the packaging bag from the outside. The two work together to achieve stable constraint on the inner and outer sides of the packaging bag, thereby effectively avoiding deformation such as bulging and bending. At the same time, since the inner support arc tube 6 and the outer hoop arc plate 19 are both arc-shaped, the packaging bag is restricted to an arc shape with a certain curvature under the action of these two, so that the two sides of the packaging bag are gathered together.

[0018] Furthermore, the radius of the inner supporting arc tube 6 is larger than the radius of the outer hoop arc plate 19. The projections of the inner supporting arc tube 6 and the outer hoop arc plate 19 on the horizontal plane intersect, and there is a gap between the far ends of their arcs. The opening gap of the U-shaped clamp 18 is smaller than the chord length of the outer hoop arc plate 19, so that the outer hoop arc plate 19 and the U-shaped clamp 18 are in an inclined closing state. This structural form can guide the packaging bag to smoothly transition from an open state to a folded state, creating favorable conditions for subsequent powder filling.

[0019] In some embodiments, a hopper 5 is provided above the workbench 1. The feeding pipe 17 of the hopper 5 is inserted into the gap between the U-shaped clamps 18. The central axis of the hopper 5 coincides with the central axis of the workbench 1 to avoid tilting due to the shift of the center of gravity. In order to adapt to the position of the hopper 5, the feeding pipe 17 is inserted into the center of the bent packaging bag. The center of the inner support arc tube 6 and the outer hoop arc plate 19 are in the same vertical plane and coincide with the central axis of the workbench 1.

[0020] In some embodiments, a guide roller 4 is provided on the support 2. The guide roller 4 is connected to the support 2 via an elastic element (not shown in the figures), and the guide roller 4 is configured to be rotatable. When the tension of the packaging bag changes, the tension value of the guide roller 4 also changes. This change in tension value will cause the elastic element to perform a compensation action, causing the guide roller 4 to slide a corresponding distance relative to the support 2, so as to adjust the tension of the packaging bag.

[0021] In some embodiments, the lower end of the outer hoop 7 is provided with a hot clamping plate 10, which is symmetrically arranged on both sides of the packaging bag and can slide relative to each other. Rollers 11 are provided below the hot clamping plate 10. The bottom end of the feeding pipe 17 of the hopper 5 is lower than the top end of the hot clamping plate 10. The rollers 11 are symmetrically arranged on both sides of the packaging bag. During the filling operation, the hot clamping plates 10 on both sides move towards each other and press the sides of the gathered packaging bag together. Under the action of high temperature, the packaging bags on both sides are glued and sealed, and the feeding pipe 17 can inject powder into the packaging bag.

[0022] In some embodiments, the lower end of the outer clamp 7 is symmetrically provided with fixing plates 8. The hot clamping plate 10 includes a first support plate 14, a second support plate 15, and a sliding rod 16. The sliding rod 16 is slidably disposed in the fixing plate 8. The first support plate 14 is disposed at the outer end of the sliding rod 16, and the second support plate 15 is disposed at the inner end of the sliding rod 16. A first cylinder 9 is provided on the fixing plate 8. The telescopic end of the first cylinder 9 is connected to the first support plate 14. In actual operation, the first cylinder 9 telescopically moves, driving the first support plate 14 to slide. The first support plate 14 drives the second support plate 15 through the sliding rod 16. The sliding action changes the distance between the two second support plates 15, enabling pressing or opening operations. It should be noted that the second support plate 15 has two mutually perpendicular longitudinal pressing protrusions and transverse pressing protrusions (not shown in the attached figures). The longitudinal pressing protrusions press the longitudinal edges of the packaging bag, and the transverse pressing protrusions press the critical areas of the two adjacent packaging bags, separating the upper and lower packaging bags into separate spaces. This prevents the powder injected from the upper part from entering the packaging bag below. After injection, the roller 11 rotates and drives the packaging bag to move downwards.

[0023] In some embodiments, a shearing table 12 and a second cylinder 13 are provided below the hot clamping plate 10. The second cylinder 13 is fixed on the shearing table 12, and a shearing blade is connected to the telescopic end of the second cylinder 13. After the packaging bag that has completed the filling and pressing of powder arrives at the shearing table 12, it is cut and separated into individual packaging bags by the shearing blade, thus completing the powder filling operation.

[0024] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0025] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
