Description

Technical Field

[0001] The utility model belongs to the technical field of cast film supports, in particular to a high-strength cast film storage rack. Background Art

[0002] Cast film, a non-stretched, non-oriented flat extruded film made by melt quenching, occupies an important position in the field of packaging composite substrates due to its excellent heat sealing performance and outstanding transparency. After processing, cast film is usually wound through a paper tube and then neatly placed on a special storage rack.

[0003] At present, in order to ensure the stable storage of cast film, the commonly used method is to fix the paper tube and the cast film thereon by an external clamping mechanism. Taking the utility model patent with announcement number CN220350432U as an example, the cast film storage rack described in the patent uses a threaded transmission to drive the clamping plate to achieve the clamping and fixing of the cast film. However, this design has significant shortcomings.

[0004] Specifically, due to the external clamping fixation method, the clamping plate will inevitably come into direct contact with the outer ring surface of the cast film. This contact may not only cause wear on the outer ring cast film surface, but also cause deformation of the paper tube, thus affecting its storage effect and subsequent use. Therefore, the storage method of cast film does need further optimization and improvement.

[0005] Therefore, it is very necessary to invent a high-strength cast film storage rack. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a high-strength cast film storage rack, comprising an adjustable bracket, a storage tray and a self-expanding fixed column, wherein a plurality of the storage trays are mounted on the adjustable bracket, and a plurality of the self-expanding fixed columns are fixedly mounted on each of the storage trays, and the paper tube of the cast film is sleeved on the self-expanding fixed column;

[0007] The adjustable bracket comprises a bracket, a mounting seat, a worm, a knob and a worm wheel. A plurality of groups of the mounting seats are fixedly mounted on the outer surface of the bracket, and the worm is rotatably mounted on each group of the mounting seats. Any end of the worm rotates through one of the mounting seats and is fixedly connected to the knob on the outer side thereof. The worm is meshed and connected with the worm wheel. The worm wheel rotates through the bracket through a core shaft and is fixedly connected to one end of the storage tray on the inner side thereof. The other end of the storage tray is rotatably mounted on the bracket.

[0008] The self-expanding fixing column includes a housing, a notch, an outer expansion body, an outer expansion head, a lower pressing plate, a connecting rod, and a spring. The lower end of the housing is fixedly installed on the self-expanding fixing column. The outer expansion body is slidably installed inside a plurality of notches opened on the housing. The outer expansion body is located between the outer expansion head and the lower pressing plate. The outer expansion head and the lower pressing plate are fixedly connected by the connecting rod. The lower pressing plate is elastically slidably installed below the housing through the spring.

[0009] Preferably, the bracket is a "U"-shaped structure made of two vertical plates and a base. One set of two mounting seats is fixedly installed on one of the vertical plates, and the other vertical plate is rotatably connected to the storage tray through a bearing seat.

[0010] Preferably, the outer expansion body is an inverted "L" - shaped structure. The upper inclined surface of the outer expansion body contacts the outer surface of the outer expansion head. The outer expansion head is a conical head. The outer expansion head is located above the middle of a plurality of the outer expansion bodies. There is a gap between the lower end of the outer expansion body and the lower pressing plate, and the two never contact each other.

[0011] Preferably, the lower pressing plate contacts the lower end of the paper tube of the cast film. The lower pressing plate is provided with a notch allowing sliding installation. The lower pressing plate is located above the spring.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model abandons the traditional fixing method that relies on external clamping and innovatively adopts an internal expansion fixing mechanism. This unique clamping mechanism is精妙ly designed and does not need to directly contact the cast film wound around the outer circle, but directly fits with the inner wall of the paper tube. This contact method not only effectively avoids the wear on the surface of the cast film but also prevents the inward concave deformation of the paper tube caused by external forces, ensuring the stable storage of the cast film and the quality of subsequent use. In addition, the introduced worm and worm gear mechanism can achieve a certain angle adjustment, thereby improving the overall operation flexibility.

[0014] More notably, the self-expanding fixing column in the utility model adopts a clever structural design. Without manual operation, it can drive the internal expansion mechanism to operate automatically only by relying on the weight of the paper tube and the cast film wound thereon. This design not only simplifies the operation process, improves work efficiency, but also greatly reduces the risk of human operation errors. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] As attached Figure 1 To Attachment Figure 3 As shown:

[0023] The utility model provides a high-strength cast film storage rack, comprising an adjustable bracket 1, a storage tray 2 and a self-expanding fixed column 3, wherein a plurality of the storage trays 2 are mounted on the adjustable bracket 1, and a plurality of the self-expanding fixed columns 3 are fixedly mounted on each of the storage trays 2, and the paper tube of the cast film is sleeved on the self-expanding fixed column 3.

[0024] The adjustable bracket 1 includes a bracket 11, a mounting base 12, a worm 13, a knob 14, and a worm gear 15. A plurality of groups of the mounting bases 12 are fixedly installed on the outer surface of the bracket 11. The worm 13 is rotatably installed on each group of the mounting bases 12. Any end of the worm 13 rotatably passes through one of the mounting bases 12 and is fixedly connected to the knob 14 outside thereof. The worm 13 is meshed with the worm gear 15. The worm gear 15 rotatably passes through the bracket 11 through a core shaft and is fixedly connected to one end of the storage tray 2 inside thereof. The other end of the storage tray 2 is rotatably installed on the bracket 11. The adjustable bracket 1 ingeniously introduces a worm and worm gear mechanism, which can realize the angle adjustment of the self-expanding fixing column 3 and the storage tray 2, thereby improving the overall operation flexibility.

[0025] The self-expanding fixing column 3 includes a housing 31, a notch 32, an outer expansion body 33, an outer expansion head 34, a lower pressing plate 35, a connecting rod 36, and a spring 37. The lower end of the housing 31 is fixedly installed on the self-expanding fixing column 3. The outer expansion body 33 is slidably installed inside the numerous notches 32 opened on the housing 31. The outer expansion body 33 is located between the outer expansion head 34 and the lower pressing plate 35. The outer expansion head 34 and the lower pressing plate 35 are fixedly connected through the connecting rod 36. The lower pressing plate 35 is elastically slidably installed below the housing 31 through the spring 37. The self-expanding fixing column 3 adopts an internal expansion fixing mechanism. This unique clamping mechanism is exquisitely designed and does not need to directly contact the cast film wound around the outer circle, but directly fits the inner wall of the paper tube.

[0026] Embodiment 1:

[0027] Specifically, the bracket 11 is a "U"-shaped structure made of two vertical plates and a base. The mounting bases 12 in groups of two are fixedly installed on one of the vertical plates. The other vertical plate is rotatably connected to the storage tray 2 through a bearing seat, enabling the storage tray 2 to rotate flexibly, which greatly facilitates the operator to pick up, place, and manage the cast film.

[0028] Specifically, the outer expansion body 33 is an inverted "L"-shaped structure, which can stably expand outward when受力 and will not be distorted or deformed. It is also beneficial to the uniform contact between the outer expansion body 33 and the inner wall of the paper tube, thereby providing a more uniform supporting force. The upper inclined surface of the outer expansion body 33 contacts the outer surface of the outer expansion head 34. The outer expansion head 34 is a conical head. The outer expansion head 34 is located above the plurality of outer expansion bodies 33. There is a spacing between the lower end of the outer expansion body 33 and the lower pressing plate 35, and the two never contact, which can ensure that the outer expansion body 33 can expand outward evenly when受到 the pressure of the outer expansion head 34.

[0029] Specifically, the lower pressing plate 35 contacts the lower end of the paper tube of the cast film, and a notch allowing sliding installation is provided on the lower pressing plate 35 . The lower pressing plate 35 is located above the spring 37 .

[0030] Embodiment 2:

[0031] Working principle of adjustable bracket 1

[0032] The adjustable bracket 1 uses a worm gear mechanism to achieve the angle adjustment of the storage tray 2. When the operator rotates the knob 14, the worm 13 connected thereto rotates accordingly. Since the worm 13 is meshed with the worm wheel 15, the worm wheel 15 rotates with the rotation of the worm 13. The worm wheel 15 is fixedly connected to one end of the storage tray 2 through a core shaft, so when the worm wheel 15 rotates, it drives the other end of the storage tray 2 (rotatably connected to the bracket 11 through a bearing seat) to adjust the angle accordingly. This design allows the operator to adjust the angle of the storage tray 2 according to actual needs, thereby improving the overall operational flexibility.

[0033] Working principle of self-expanding fixed column 3

[0034] The self-expanding fixed column 3 adopts an internal expansion fixing mechanism, and the outward expansion of the external expansion body 33 is achieved through the elastic force of the spring 37. When the paper tube of the cast film is inserted into the self-expanding fixed column 3, the lower end of the paper tube contacts the lower pressure plate 35, and the lower pressure plate 35 moves downward under pressure, compressing the spring 37. Since the external expansion body 33 is located between the external expansion head 34 and the lower pressure plate 35, and is connected to the external expansion head 34 through the connecting rod 36, when the lower pressure plate 35 moves downward, the external expansion head 34 will also drop. Since the upper end inclined surface of the external expansion body 33 contacts the outer surface of the external expansion head 34, the external expansion body 33 will expand outward under the elastic force of the spring 37, close to the inner wall of the paper tube, thereby achieving stable fixation of the paper tube.

[0035] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
