Description

Technical Field

[0001] This application relates to the field of automated processing technology, and in particular to a hot-press cutting device for CD packaging bags. Background Technology

[0002] CD packaging bags are typically made by laminating multiple layers of film, then heat-sealing and cutting them. They need to have a single-sided opening to accommodate the placement and removal of CDs. During the processing, the multiple layers of film must be precisely cut and the edges heat-sealed simultaneously to ensure the airtightness and structural stability of the packaging bag.

[0003] In existing technologies, the heat-sealing and cutting processes for multi-layer film CD packaging bags are often performed separately. Specifically, the edges of the multi-layer film are first heat-sealed using a separate device, and then the outer shape of the packaging bag is cut using another cutting device. This separate processing method has significant drawbacks. It easily leads to difficulty in accurately aligning the sealing position with the cutting edge, affecting the dimensional accuracy and sealing effect of the CD packaging bag, and consequently impacting the bag's protective performance for the CD. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a hot-press cutting device for CD packaging bags, which can improve processing efficiency and accuracy.

[0005] This application provides a CD packaging bag hot-press cutting device, including: Installation platform; A hot-press cutting mechanism is mounted on the mounting platform and includes a positioning base plate, a cutting drive structure, and a heating structure.

[0023] CD packaging bags are typically made by laminating multiple layers of film, then heat-sealing and cutting them. They need to have a single-sided opening to accommodate the placement and removal of discs. During processing, precise cutting of the multiple layers of film and heat-sealing of the edges are required simultaneously to ensure the bag's airtightness and structural stability. In existing technology, the heat-sealing and cutting processes for multi-layered film CD packaging bags are often performed separately. That is, the edges of the multiple layers of film are first heat-sealed using a separate device, and then the outer shape of the packaging bag is cut using another cutting device. This separate processing method has significant shortcomings, easily leading to difficulty in accurately aligning the sealing position with the cutting edge, affecting the dimensional accuracy and sealing effect of the CD packaging bag, and consequently affecting the packaging bag's protective performance for the discs.

[0024] Based on this, this application provides a CD packaging bag 610 hot pressing and cutting device to solve the above-mentioned technical problems. The technical solutions provided by this application will be described in detail below.

[0025] Reference Figures 1 to 4 This application provides a hot-press cutting device for CD packaging bags 610, including: an installation platform 100, a hot-press cutting mechanism, and a waste discharge mechanism. The hot-press cutting mechanism is disposed on the installation platform 100 and includes a positioning base plate 200, a cutting drive structure, and a heating structure. The positioning base plate 200 is used to place multiple layers of film to be processed. The cutting drive structure is disposed above the positioning base plate 200. The heating structure is disposed on the cutting drive structure and is used to heat the cutting surface of the cutting drive structure. The cutting drive structure is used to cut the multiple layers of film according to a preset cutting shape and to hot-press and seal the multiple layers of film at the cut edge to form a CD packaging bag 610 with a single-sided opening. The waste discharge mechanism is disposed on the installation platform 100 and located on the waste material 620 discharge side of the hot-press cutting mechanism and is used to grab the waste material 620 cut from the hot-press cutting mechanism.

[0026] During operation, the multi-layered film to be processed is first placed on the positioning base plate 200 for positioning. Then, the heating structure is activated to preheat the cutting surface of the cutting drive structure. After the cutting surface reaches the preset temperature, the cutting drive structure moves downward, cutting the multi-layered film according to the preset cutting shape on one hand, and applying pressure to the multi-layered film at the cutting edge through the heated cutting surface to perform hot-press sealing on the edge. The cutting and sealing processes are completed simultaneously to directly form a single-sided open packaging bag for the CD to be processed. The waste material 620 generated during cutting is promptly picked up and discharged by the waste removal mechanism. By integrating the hot-press sealing and cutting processes into one unit, this device effectively solves the problem of inaccurate alignment between the sealing position and the cutting edge in existing separate processing methods. It ensures the dimensional accuracy and sealing performance of the packaging bag for the CD to be processed, improving the protection performance of the disc. Furthermore, the integrated processing and waste removal mechanism improve the processing efficiency and accuracy.

[0027] Reference Figures 1 to 3It is understood that the cutting drive structure includes a mounting bracket 310, a drive unit 320, and a cutting die. The mounting bracket 310 is horizontally positioned across both sides of the positioning base plate 200. The drive unit 320 is positioned on top of the mounting bracket 310. The cutting die is positioned within the mounting bracket 310 and above the positioning base plate 200. The drive end of the drive unit 320 passes through the mounting bracket 310 and connects to the cutting die, driving the cutting die towards the positioning base plate 200. A heating structure is positioned on the cutting die. During operation, the heating structure preheats the cutting die. Once the preset temperature is reached, the drive unit 320 drives the cutting die towards the positioning base plate 200, enabling the cutting die to both cut the multi-layer film according to a preset shape and achieve heat sealing of the multi-layer film through the heated edge of the die. The structure ensures the stability of the cutting drive process through the mounting bracket 310, and the drive unit 320 provides a precise and stable driving force to the cutting die head, ensuring that the cutting and hot sealing actions are synchronized and executed accurately. This effectively avoids the problem of misalignment between the sealing and cutting edges, further improving the processing accuracy and sealing reliability of the CDs and packaging bags to be processed. At the same time, it simplifies the transmission logic of the overall mechanism, ensuring a smooth and efficient processing process.

[0028] It should be noted that the drive unit 320 can be a cylinder, a hydraulic cylinder or a servo motor. This application does not make specific limitations on the specific structural selection of the drive unit 320.

[0029] Reference Figure 3 It is understood that the cutting die head includes a first connecting plate 331 and a cutting plate 332, and the heating structure includes a heating plate 500. The upper surface of the first connecting plate 331 is connected to the driving end of the driving unit 320, and the lower surface of the first connecting plate 331 is connected to the cutting plate 332 through the heating plate 500. The driving force of the driving unit 320 is smoothly transmitted to the heating plate 500 and the cutting plate 332 through the first connecting plate 331. After the heating plate 500 is started, it evenly heats the cutting plate 332, so that the cutting plate 332 reaches the preset hot-pressing and sealing temperature. Then, with the downward movement of the driving unit 320, the preset shape cutting of the multilayer film and the edge hot-pressing and sealing are completed synchronously. This structure ensures the stability of the driving force transmission through the first connecting plate 331, and the direct connection between the heating plate 500 and the cutting plate 332 makes the heat transfer more uniform and efficient. This not only further improves the cutting size accuracy and sealing performance of the CD packaging bag 610, but also simplifies the assembly relationship between components and enhances the reliability of the device operation.

[0030] In another embodiment, the heating structure can be an electric heating wire disposed within the cutting die head, or a coil for induction heating of the cutting die head. Specifically, when the heating structure is an electric heating wire, the electric heating wire is embedded inside the cutting die head and forms a thermal conductive connection with the cutting plate and cutting blade. During operation, the electric heating wire generates heat after being energized and quickly transfers it to the cutting plate and cutting blade, so that the cutting blade reaches the preset hot-pressing and sealing temperature. This, combined with the drive of the driving cylinder, completes the synchronous cutting and sealing of the multi-layer film. When the heating structure is a coil for induction heating of the cutting die head, the coil is disposed around the outside of the cutting die head without contact with it. During operation, the coil passes an alternating current to generate an alternating magnetic field. The cutting die head generates heat under the action of the magnetic field and transfers the heat to the cutting blade, thus heating the cutting blade. Both embodiments can meet the temperature requirements for hot-pressing and sealing of multi-layer films, ensuring the processing quality of CD packaging bags.

[0031] Reference Figure 1 and Figure 3 It is understandable that the lower surface of the cutting plate 332 is provided with a cutting blade 333. The shape of the cutting blade 333 matches the preset cutting shape and is used to cut the multi-layer film and perform hot-press sealing on the cut edge. After being heated by the heating plate 500, the cutting plate 332 moves towards the positioning base plate 200 driven by the driving unit 320. The cutting blade 333 first uses its own shape to accurately cut the multi-layer film on the positioning base plate 200. At the same time, because the cutting blade 333 is heated to the preset temperature along with the cutting plate 332, at the moment the cutting is completed, the cutting blade 333 will directly apply pressure to the multi-layer film at the cut edge and perform hot-press sealing, realizing the synchronous linkage of cutting and sealing. This structure integrates the cutting function and the hot-press sealing function onto the cutting blade 333, ensuring a precise correspondence between the cutting shape and the sealing range. This effectively avoids the problem of misalignment between the two, improving the edge regularity and sealing performance of the CD packaging bag 610. It also makes the synchronous processing action more direct and efficient, further ensuring the processing accuracy and operational reliability of the device.

[0032] Reference Figures 1 to 3It is understood that the cutting die head also includes a second connecting plate 334 and an adjusting connector 335. The second connecting plate 334 is disposed between the first connecting plate 331 and the drive unit 320. The upper surface of the second connecting plate 334 is connected to the drive end of the drive unit 320. The second connecting plate 334 is connected to the first connecting plate 331 through the adjusting connector 335. By adjusting the relative position of the second connecting plate 334 and the first connecting plate 331 through the adjusting connector 335, the height and horizontal position of the cutting blade 333 relative to the positioning base plate 200 can be precisely adjusted, making the position adjustment of the cutting die head more convenient and flexible. This allows it to adapt to the processing of multi-layer films of different thicknesses or the need for precise alignment, further improving the cutting and sealing accuracy of the CD packaging bag 610 and enhancing the practicality and operational reliability of the device.

[0033] Reference Figure 1 and Figure 2 It is understood that the upper surface of the second connecting plate 334 is provided with a guide post 336, and the mounting bracket 310 is provided with a guide sleeve 311 that matches the guide post 336. When the drive unit 320 drives the second connecting plate 334 to move the first connecting plate 331, the heating plate 500, the cutting plate 332 and the cutting blade 333 up and down, the guide post 336 will slide synchronously along the guide sleeve 311, forming a precise guide and limit for the movement direction of the second connecting plate 334, effectively preventing the second connecting plate 334 from deviating or tilting during the movement, and ensuring the precise alignment of the cutting blade 333 and the positioning base plate 200.

[0034] Reference Figures 1 to 3 It is understandable that the positioning base plate 200 is equipped with a positioning block 210, which is used to position the multi-layer film to be processed. During operation, the multi-layer film to be processed is placed on the positioning base plate 200, and the positioning block 210 precisely limits and calibrates the placement of the film, ensuring that the film is always within the preset processing area. This prevents displacement during cutting and heat sealing, thus ensuring precise alignment between the cutting blade 333 and the film. This further improves the cutting dimensional accuracy of the CD packaging bag 610 and the consistency of the edge heat sealing, while simplifying the film placement operation and enhancing the convenience and reliability of the device.

[0035] Reference Figure 1 , Figure 2 and Figure 4It is understood that the waste discharge mechanism includes a pen-shaped cylinder 410 and a gripper cylinder 420. The pen-shaped cylinder 410 is mounted on the mounting platform 100 and located on the waste material 620 discharge side of the hot-press cutting mechanism. Its drive end is connected to the gripper cylinder 420, which is used to drive the gripper cylinder 420 to move closer to or away from the hot-press cutting mechanism. The gripper cylinder 420 is used to grab the waste material 620 cut by the hot-press cutting mechanism. After the hot-press cutting mechanism completes the cutting and hot-press sealing of the multi-layer film, the pen-shaped cylinder 410 drives the gripper cylinder 420 to move closer to the hot-press cutting mechanism. After the gripper cylinder 420 grabs the cut waste material 620, the pen-shaped cylinder 410 then drives the gripper cylinder 420 away from the hot-press cutting mechanism, realizing the rapid transfer and discharge of the waste material 620. This structure can promptly remove the processed waste material 620, preventing it from accumulating on the positioning base plate 200 or the cutting area and affecting subsequent processing. This ensures the smooth continuous processing of the device. At the same time, the cooperation between the pen-shaped cylinder 410 and the gripper cylinder 420 makes the grabbing and transfer of waste material 620 precise and efficient, simplifying the waste removal operation.

[0036] Reference Figure 1 It is understandable that the waste discharge mechanism also includes a waste material 620 collection structure 430, which is located below the installation platform 100. The installation platform 100 has a discharge port at the location of the waste material 620 collection structure 430, which receives the waste material 620 gripped by the gripper cylinder 420. After the pen-shaped cylinder 410 drives the gripper cylinder 420 to grip the waste material 620 cut by the hot-press cutting mechanism, it moves the gripper cylinder 420 above the discharge port. Then, the gripper cylinder 420 releases the waste material 620, which falls directly into the waste material 620 collection structure 430 through the discharge port for centralized collection. This structure prevents the waste material 620 from scattering randomly, affecting the cleanliness of the processing environment or interfering with subsequent cutting and hot-press sealing operations, further ensuring the smoothness of continuous processing and reducing the frequency of manual cleaning of the waste material 620.

[0037] Understandably, the positioning block 210 is adjustable and mounted on the positioning base plate 200. During operation, the mounting position of the positioning block 210 on the positioning base plate 200 can be flexibly adjusted according to the size of the multi-layer film to be processed or the preset cutting shape, so that it can always form precise limit and calibration for films of different specifications, ensuring that the film is stably placed in the preset processing area and avoiding displacement during cutting and hot pressing edge sealing.

[0038] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
