Description

Technical Field

[0001] This application belongs to the field of anchoring agent processing technology, specifically relating to a packaging film winding and forming device. Background Technology

[0002] Anchoring agent is a two-component, putty-like adhesive material formulated with unsaturated polyester resin, curing agent, accelerator, etc. It is packaged in rolls using polyester film separators and is mainly used in coal mine shaft support, tunnel construction, building structure reinforcement, and equipment foundation fixing. The outer packaging of anchoring agent is commonly made of polyester or aluminum-plastic composite film. This film is not easily dissolved and does not chemically react with the main components of the anchoring agent, protecting the product from environmental damage. It is primarily used for the transportation and protection of the anchoring agent.

[0003] Currently, packaging machines typically use bag-forming units to roll the packaging film into a cylindrical shape. However, the cylinder of the bag-forming unit wears down over time, which can scratch the packaging film and affect its quality. Since the bag-forming unit is an integrated device, the entire unit needs to be replaced, resulting in high replacement costs. Utility Model Content

[0004] This application provides a packaging film winding and forming device, which aims to solve the technical problem in the prior art where the integrated and frequently replaced anchoring agent packaging bag forming device leads to high operating costs.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] A packaging film winding forming device is provided, comprising:

[0007] Base;

[0008] The molding device body is mounted on the base, and a fixing groove is provided on one side of the molding device body;

[0009] An arc-shaped mating piece is installed in the fixing groove;

[0010] The first molding piece is mounted on the molding machine body and located on one side of the fixing groove; and

[0011] The second forming piece is installed on the forming device body and located on the other side of the fixing groove. The first forming piece, the second forming piece, and the mating piece enclose a cylindrical winding space.

[0012] In one possible implementation, the first molded sheet includes an integrally formed first mounting plate and a first arc-shaped structure. The first mounting plate is mounted on the side wall of the molding body. A seam gap is left between the inner arc surface of the first arc-shaped structure and the second molded sheet. The seam gap corresponds to the seam of the packaging film.

[0013] In one possible implementation, the second molding sheet includes an integrally formed second mounting plate and a second arc-shaped structure, the second mounting plate being mounted on the side wall of the molding body;

[0014] A first channel is formed between the outer arc surface of the second arc structure and the inner arc surface of the first arc structure. The first channel forms the seam gap. The outer arc surface of the second arc structure also forms a second channel with the inner arc surface of the mating piece. The second channel corresponds to the transition section of the packaging film. The inner arc surface of the second arc structure and the inner arc surface of the mating piece form a molding space. The molding space corresponds to the main body of the packaging film. The first channel, the second channel, and the molding space are connected sequentially to form the winding space.

[0015] In one possible implementation, the molding body has a first connecting groove corresponding to the first mounting plate, and the first connecting groove and the first mounting plate are engaged to limit the displacement of the first mounting plate in the vertical direction.

[0016] The molding body has a second connecting groove corresponding to the second mounting plate. The second connecting groove and the second mounting plate are engaged to restrict the displacement of the second mounting plate in the vertical direction.

[0017] In one possible implementation, the height of the first arc-shaped structure gradually decreases in the direction away from the first mounting plate; the height of the second arc-shaped structure gradually decreases in the direction away from the second mounting plate.

[0018] In one possible implementation, the second mounting plate has a screw hole, and the second connecting groove has a connecting hole corresponding to the screw hole. The second mounting plate and the molding body are connected by fasteners that pass through the screw hole and the connecting hole.

[0019] In one possible implementation, the second mounting plate has a pressure-distributing notch that communicates with the screw hole and has its other end connected to the side of the second mounting plate. The pressure-distributing notch is used to distribute the pressure of the screw hole.

[0020] In one possible implementation, the base is provided with mounting holes for connection to anchoring agent processing equipment.

[0021] In one possible implementation, the outer periphery of the mating piece conforms to the shape of the fixing groove to restrict the displacement of the mating piece in the circumferential direction.

[0022] In one possible implementation, the base has an installation groove corresponding to the fixing groove, the installation groove is aligned vertically with the fixing groove, and the mating piece is simultaneously inserted and fixed into both the fixing groove and the installation groove.

[0023] The packaging film winding and forming device provided in this application, compared with the prior art, involves introducing one end of the packaging film into a cylindrical winding space formed by a first forming sheet, a second forming sheet, and a mating sheet during operation. The packaging film is continuously drawn into the inner wall of the winding space, gradually transforming into a cylindrical structure within it. Compared to traditional integrated bag-forming machines, this structural design allows the mating sheet, the first forming sheet, and the second forming sheet to be installed and disassembled independently. When a part wears out, only the corresponding worn component needs to be replaced, eliminating the need to replace the entire device, significantly reducing replacement costs. Furthermore, this modular structure allows the size of the winding space to be adjusted by replacing different specifications of the mating sheet, the first forming sheet, and the second forming sheet, adapting to the winding requirements of different sized packaging films and improving the versatility of the forming device.

The following description of at least one exemplary embodiment is actually illustrative only and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0045] It should also be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "linking," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0046] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Additionally, "multiple" and "several" mean two or more, unless otherwise explicitly specified.

[0047] Please refer to the following: Figures 1 to 9 The packaging film winding and forming device provided in this application will now be described. The packaging film winding and forming device includes a base 1, a forming device body 2, an arc-shaped mating piece 3, a first forming piece 4, and a second forming piece 5. The forming device body 2 is mounted on the base 1, and a fixing groove 21 is formed on one side of the forming device body 2; the mating piece 3 is installed in the fixing groove 21; the first forming piece 4 is mounted on the forming device body 2 and located on one side of the fixing groove 21; the second forming piece 5 is mounted on the forming device body 2 and located on the other side of the fixing groove 21. The first forming piece 4, the second forming piece 5, and the mating piece 3 together form a cylindrical winding space.

[0048] In practice, the first forming piece 4, the second forming piece 5, and the mating piece 3 are all made of stainless steel or alloy metal plates to ensure the high strength of the structure.

[0049] As a connection method between the mating piece 3 and the molding body 2, the molding body 2 has a tightening hole, which is connected to the fixing groove 21 and extends radially along the winding space. A set screw is provided in the tightening hole, which tightens the mating piece 3 and fixes the mating piece 3 in the fixing groove 21.

[0050] It should be noted that the outer surface of the forming body 2 is the guide surface 25. The initial shape of the packaging film is square. The packaging film is attached to the guide surface 25, and then the packaging film is pulled into the winding space. The packaging film is attached to the inner wall of the winding space and enters the winding space, changing from a square shape to a cylindrical structure.

[0051] It should be noted that the beneficial effects of this application are as follows: the first molding piece 4, the second molding piece 5 and the mating piece 3 are used to form a winding space. The winding space is a combined space. When one of the first molding piece 4, the second molding piece 5 and the mating piece 3 is worn, the worn part can be replaced individually without replacing the whole device. The individual parts are easy to disassemble, which can improve the replacement efficiency.

[0052] The packaging film winding and forming device of this application can not only wind the packaging film of anchoring agent, but also be applied to the food industry and chemical industry, and is applicable to similar packaging films that need to be wound into a cylindrical shape.

[0053] The packaging film winding and forming device provided in this embodiment, compared with the prior art, involves the packaging film adhering to the outer surface of the forming device body during operation. One end of the packaging film is then introduced into the cylindrical winding space formed by the first forming piece 4, the second forming piece 5, and the mating piece 3. As the packaging film is continuously introduced, it gradually takes shape within the winding space. Compared with the traditional integrated bag forming device of a packaging machine, this structural design allows the mating piece 3, the first forming piece 4, and the second forming piece 5 to be installed and disassembled individually. When a certain part wears out, only the corresponding worn part needs to be replaced, without replacing the entire device, greatly reducing replacement costs. At the same time, this modular structure allows the size of the winding space to be adjusted by replacing different specifications of the mating piece 3, the first forming piece 4, and the second forming piece 5, which can adapt to the winding requirements of different sizes of packaging films and improve the versatility of the forming device.

[0054] In some embodiments, see Figures 1 to 5 The first forming sheet 4 includes an integrally formed first mounting plate 41 and a first arc-shaped structure 42. The first mounting plate 41 is mounted on the side wall of the forming device body 2. A seam gap is left between the inner arc surface of the first arc-shaped structure 42 and the second forming sheet 5, corresponding to the packaging edge of the packaging film. The first mounting plate 41 securely mounts the first forming sheet 4 onto the forming device body 2, ensuring that the first forming sheet 4 will not shift during the packaging film winding process. The gap between the inner arc surface of the first arc-shaped structure 42 and the second forming sheet 5 allows the packaging film to enter the winding space more smoothly from the guide surface 25 during the winding process, avoiding excessive compression or scratches to the packaging film caused by direct contact between the first arc-shaped structure 42 and the second forming sheet 5, thus improving the quality of packaging film winding and also facilitating the winding operation of packaging films of different thicknesses.

[0055] In some embodiments, see Figures 1 to 5The second molding sheet 5 includes an integrally formed second mounting plate 51 and a second arc-shaped structure 52. The second mounting plate 51 is installed on the side wall of the molding body 2. A first channel 6 is formed between the outer arc surface of the second arc-shaped structure 52 and the inner arc surface of the first arc-shaped structure 42. The first channel 6 forms a seam gap. The outer arc surface of the second arc-shaped structure 52 also surrounds the inner arc surface of the mating sheet 3 to form a second channel 7. The second channel 7 corresponds to the transition section of the packaging film. The inner arc surface of the second arc-shaped structure 52 surrounds the inner arc surface of the mating sheet 3 to form a molding space 8. The molding space 8 corresponds to the main body of the packaging film. The first channel 6, the second channel 7 and the molding space 8 are connected sequentially to form a winding space.

[0056] It should be noted that the packaging film is initially a square structure. After entering the winding space from the upper surface of the forming body 2, one side of the packaging film enters the first channel 6 and then bends along the first channel 6. The other side of the packaging film enters the forming space 8 and is wound into a cylindrical body. The transition section between the side of the first channel 6 and the main body of the packaging film enters the second channel 7, thereby changing the shape of the packaging film and forming it into a cylindrical structure.

[0057] In this embodiment, the second mounting plate 51 ensures the stable mounting of the second forming sheet 5 on the forming device body 2. The first channel 6 and the second channel 7 provide a guiding path for the packaging film to enter the winding space. The packaging film can first pass through the first channel 6, then through the second channel 7, and finally enter the forming space 8 for winding. This step-by-step guiding method makes the packaging film enter the winding space more smoothly and accurately, reducing the possibility of problems such as deviation and wrinkles during the introduction of the packaging film, and further improving the quality and stability of the packaging film winding forming.

[0058] In some embodiments, see Figure 4 and Figure 5 The molding body 2 has a first connecting groove 22 corresponding to the first mounting plate 41. The first connecting groove 22 and the first mounting plate 41 are engaged to restrict the displacement of the first mounting plate 41 in the vertical direction. The molding body 2 has a second connecting groove 23 corresponding to the second mounting plate 51. The second connecting groove 23 and the second mounting plate 51 are engaged to restrict the displacement of the second mounting plate 51 in the vertical direction.

[0059] In this embodiment, the snap-fit ​​engagement between the first connecting groove 22 and the first mounting plate 41, and the snap-fit ​​engagement between the second connecting groove 23 and the second mounting plate 51, makes the installation process of the first molding sheet 4 and the second molding sheet 5 simpler and faster. When it is necessary to replace worn parts, the old first molding sheet 4 and the second molding sheet 5 can be quickly removed from the molding machine body 2, and the new parts can be easily installed, improving the efficiency of equipment maintenance and reducing equipment downtime. Moreover, the snap-fit ​​engagement method ensures the firmness of the installation of the first molding sheet 4 and the second molding sheet 5 on the molding machine body 2, ensuring that the parts will not loosen during the packaging film winding process and ensuring the normal operation of the winding work.

[0060] In some embodiments, see Figures 6 to 9 The height of the first arc-shaped structure 42 gradually decreases in the direction away from the first mounting plate 41; the height of the second arc-shaped structure 52 gradually decreases in the direction away from the second mounting plate 51. As the packaging film enters the winding space along the first channel 6 and the second channel 7, it is gradually gathered into the winding space, which helps the packaging film to be wound more tightly and neatly in the winding space, improving the tightness and appearance quality of the wound packaging film, and also reducing the probability of problems such as looseness and uneven overlap of the packaging film during the winding process.

[0061] It should be noted that the height of the first arc-shaped structure 42 refers to the vertical dimension of the first arc-shaped structure 42, and the height of the second arc-shaped structure 52 refers to the vertical dimension of the second arc-shaped structure 52.

[0062] In some embodiments, see Figure 4 and Figure 5 The second mounting plate 51 has screw holes 511, and the second connecting groove 23 has connecting holes 24 corresponding to the screw holes 511. The second mounting plate 51 and the forming device body 2 are connected by fasteners that pass through the screw holes and connecting holes. Using fasteners for screw connection further enhances the stability of the connection between the second forming sheet 5 and the forming device body 2, ensures the stability and accuracy of the packaging film winding, and also improves the service life of the equipment.

[0063] In specific implementation, the first mounting plate 41 also has screw holes 511, and the first connecting groove 22 has corresponding connecting holes 24. The first mounting plate 41 and the molding body 2 are also fixedly connected by fasteners.

[0064] As a specific implementation of the fastener, the fastener is a bolt with a nut. The bolt is sequentially screwed into the screw hole 511 and the connecting hole 24 to connect the second mounting plate 51 and the forming body 2 together. The fastener is easy to disassemble and assemble, and can be quickly replaced by employees. The operation is easy and the replacement efficiency of the first forming plate 4 and the second forming plate 5 is high.

[0065] In some embodiments, see Figures 7 to 9 The second mounting plate 51 has a pressure-distributing notch 53, which communicates with the screw hole 511 at one end and is connected to the side of the second mounting plate 51 at the other end. The pressure-distributing notch 53 is used to distribute the pressure of the screw hole 511. The pressure-distributing notch 53 can compensate for dimensional errors in the manufacturing and assembly of parts, making the screw hole 511 more flexible in its fit with bolts, etc., facilitating installation, and also making it easier for later maintenance and adjustment, avoiding assembly difficulties or structural stress concentration caused by errors.

[0066] In some embodiments, see Figure 1 and Figure 5 The base 1 has mounting holes 11 for connecting to the anchoring agent processing equipment. The mounting holes 11 on the base 1 allow the packaging film winding and forming machine to be easily and quickly connected to the anchoring agent processing equipment, thus achieving effective integration of the packaging film winding process and the anchoring agent processing production line.

[0067] In some embodiments, the outer periphery of the mating piece 3 conforms to the shape of the fixing groove 21 to restrict the displacement of the mating piece 3 in the circumferential direction. This ensures the installation accuracy and stability of the mating piece 3 within the fixing groove 21. During the packaging film winding process, the mating piece 3 can fit tightly with the fixing groove 21 without shaking or displacement, thereby ensuring that the shape and size of the winding space remain stable.

[0068] In some embodiments, see Figure 4 and Figure 5 The base 1 has an installation groove 12 corresponding to the fixing groove 21. The installation groove 12 is vertically aligned with the fixing groove 21, and the mating piece 3 is simultaneously inserted and fixed into both the fixing groove 21 and the installation groove 12. The installation groove 12 on the base 1, with its vertical alignment with the fixing groove 21 and the simultaneous insertion and mating of the mating piece 3 into both, further enhances the installation firmness of the mating piece 3. This ensures that the mating piece 3 remains stable under various external forces during the packaging film winding process, preventing it from easily falling off or shifting. This guarantees the stability of the winding space, which is beneficial for improving the quality of packaging film winding and the reliability of equipment operation, while also extending the service life of the mating piece 3 and the entire packaging film winding and forming machine.

[0069] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
