However, this conventional die-cutting production equipment has a relatively complex structure, leading to increased equipment maintenance costs. It includes multiple die-cutting machines and material belt buffer devices, requiring more space for installation and operation. Therefore, it is necessary to optimize its structure to overcome the above-mentioned shortcomings. Utility Model Content

[0003] The purpose of this invention is to provide a paper cover die-cutting device with a lateral conveying structure to reduce equipment space occupation and equipment cost, and improve its processing efficiency.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A paper cap die-cutting apparatus with a lateral conveying structure includes:

[0006] A support component having a load-bearing space;

[0007] The die-cutting assembly is installed in the support and bearing assembly and is connected to the paperboard feeding mechanism and the waste edge discharge mechanism. The paperboard feeding mechanism supplies paperboard to the die-cutting assembly, and the die-cutting assembly performs die-cutting on the paperboard to form a paper cover and waste edge. The waste edge is discharged by the waste edge discharge mechanism.

[0008] It also includes:

[0009] A paper cover support assembly is installed in a support and bearing assembly and cooperates with a die-cutting and forming assembly. The paper cover formed in the die-cutting and forming assembly can enter the paper cover support assembly and be supported by the paper cover support assembly.

[0010] A paper cover conveying assembly is installed in a support and bearing assembly. Its conveying direction intersects with that of the paperboard feeding mechanism and the waste edge discharge mechanism, and it cooperates with the paper cover support assembly. The paper cover in the paper cover support assembly can enter the paper cover conveying assembly and be conveyed by the paper cover conveying assembly.

[0011] A carrier switching assembly is installed in the support and bearing assembly and engages with the paper cover carrier assembly. The carrier switching assembly switches the state of the paper cover carrier assembly so that it can support the paper cover or release it into the paper cover conveying assembly.

[0012] The supporting load-bearing components include:

[0013] The supporting outer frame is formed by enclosing pipes and plates and arranged vertically to form a load-bearing space inside.

[0014] The inner support frame is installed on the outer support frame, and the die-cutting and forming assembly, the paper cover carrier assembly, and the paper cover conveying assembly are installed in the inner support frame.

[0015] The die-cutting components include:

[0016] A forming base plate is installed in the inner support frame. Its top has a space for placing cardboard, and its interior has a paper cover discharge port.

[0017] A forming plate is installed above a forming base plate via a guide structure and is connected to a power drive mechanism. A cutting die is provided at its bottom. The power drive mechanism drives the forming plate to move, so that the cutting die performs die-cutting on the cardboard on the forming base plate to form a paper cover and waste edge. The paper cover is discharged from the paper cover discharge port, and the waste edge is discharged from the waste edge discharge mechanism.

[0018] The paper cover carrier assembly includes:

[0019] The support strips are provided in at least one pair. Each support strip is located below the forming base plate and is arranged on both sides of the paper cover discharge port. The paper cover discharged from the paper cover discharge port can fall onto the support strips and be supported by the support strips.

[0020] The paper cover conveyor assembly includes:

[0021] The conveyor belt is installed in the inner frame of the support structure. It is located below the pallet strip and intersects the conveying direction of the cardboard feeding mechanism and the waste edge discharge mechanism. It is connected to the conveyor motor and the conveyor belt is driven by the conveyor motor. The paper cover on the pallet strip can fall onto the conveyor belt and be conveyed by the conveyor belt.

[0022] The carrier switching components include:

[0023] The switching cylinder is provided in at least one pair. The fixed parts of each switching cylinder are respectively installed in the inner frame of the support, and its moving parts are engaged with the support plate strips. The switching cylinder drives the support plate strips to move closer or further apart. When the support plate strips move closer, their spacing is less than the width of the paper cover, so that the paper cover can be supported. When the support plate strips move further apart, their spacing is greater than the width of the paper cover, so that the paper cover can fall onto the conveyor belt.

[0024] The conveyor belt is made of anti-slip and wear-resistant material, and its operating speed matches the rhythm of the die-cutting and forming components and the carrier switching components, ensuring that the cardboard can be conveyed smoothly and quickly. At the same time, a correction device is installed on the side of the conveyor belt. If a product position deviation is detected during the conveying process, the correction device on the side of the conveyor belt will be automatically activated to adjust the position of the paper cover, ensuring the accuracy of the conveying process.

[0025] In one embodiment of this utility model, the piston rods of each switching cylinder are in opposite directions, and their ends are fixedly installed in the inner support frame. The cylinder body of the switching cylinder is engaged with the support plate strip, which can move on the piston rod and drive the support plate strip to move closer or further away from each other.

[0026] The advantages of this utility model are:

[0027] This paper cover die-cutting device features pairs of support strips below the forming base plate. These support strips stably support the paper covers and allow multiple paper covers to be stacked. The support strips are moved closer or further apart by a switching cylinder, supporting the paper covers or causing them to fall onto the conveyor belt. This allows for timely response to production needs and seamless connection between the support and conveyor. The conveyor belt intersects with the paperboard feeding mechanism and the waste edge discharge mechanism, avoiding potential spatial conflicts that may occur when the conveying directions of each mechanism are consistent. This necessitates that the die-cutting device possess high efficiency, high precision, and high stability, enabling rapid switching between paper and aluminum cover die-cutting, reducing equipment costs, and improving equipment utilization.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0032] like Figures 1-3 As shown, the paper cover die-cutting device with a lateral conveying structure proposed in this utility model includes a support and bearing assembly, a die-cutting and forming assembly, a paper cover carrier assembly, a paper cover conveying assembly, and a carrier switching assembly. The support and bearing assembly has a bearing space. The die-cutting and forming assembly is installed in the support and bearing assembly and is connected to the cardboard feeding mechanism and the waste edge discharge mechanism. The cardboard feeding mechanism supplies cardboard to the die-cutting and forming assembly, which then performs die-cutting to form the paper cover and waste edge. The waste edge is discharged by the waste edge discharge mechanism. The paper cover carrier assembly is installed in the support and bearing assembly and is coordinated with the die-cutting and forming assembly. The paper cover formed in the die-cutting component can enter the paper cover support component, where it is supported. The paper cover conveying component is installed in the support component, and its conveying direction intersects with that of the paperboard feeding mechanism and the waste edge discharge mechanism. It also cooperates with the paper cover support component. The paper cover in the paper cover support component can enter the paper cover conveying component, where it is conveyed. The support switching component is installed in the support component and engages with the paper cover support component. The support switching component switches the state of the paper cover support component, so that it supports the paper cover or releases it into the paper cover conveying component.

[0033] The supporting load-bearing component includes a supporting outer frame 110 and a supporting inner frame 120. The supporting outer frame is formed by enclosing pipes and plates and is arranged vertically to form a load-bearing space inside. The supporting inner frame is installed in the supporting outer frame, and the die-cutting forming component, the paper cover carrier component, and the paper cover conveying component are installed in the supporting inner frame.

[0034] The die-cutting assembly includes a forming base plate 210 and a forming pressure plate 220. The forming base plate is installed in the supporting inner frame and has a space at its top for placing cardboard. It also has a paper cover discharge port inside. The forming pressure plate is installed above the forming base plate via a guide structure and is connected to a power drive mechanism. A cutting die is located at its bottom. The power drive mechanism drives the forming pressure plate to move, causing the cutting die to die-cut the cardboard on the forming base plate, forming a paper cover and waste edge. The paper cover is discharged from the paper cover discharge port, and the waste edge is discharged from the waste edge discharge mechanism. The specific structure and power mechanism of the die-cutting assembly are based on existing technology and are therefore not described in detail. The cardboard feeding mechanism and waste edge discharge mechanism are also based on existing technology and are therefore not described in detail.

[0035] The paper cover support assembly includes support strips 300, with at least one pair of support strips. Each support strip is located below the forming base plate and is arranged on both sides of the paper cover discharge port. The paper cover discharged from the paper cover discharge port can fall onto the support strips and be supported by the support strips.

[0036] The paper cover conveying assembly includes a conveyor belt 400, which is installed in the inner support frame below the carrier trays. The conveyor belt intersects the conveying direction of the cardboard feeding mechanism and the waste edge discharge mechanism, and is connected to a conveyor motor. The conveyor motor drives the conveyor belt, allowing paper covers on the carrier trays to fall onto the conveyor belt for transport. Other structures used in conjunction with the conveyor belt, such as the rollers at both ends and the transmission structure connected to the conveyor motor, are existing technologies and therefore not described in detail.

[0037] The carrier switching assembly includes switching cylinders 500, with at least one pair of cylinders. The fixed parts of each switching cylinder are installed in the inner support frame, and their moving parts engage with carrier strips. The switching cylinders drive the carrier strips to move closer or further apart. When the carrier strips move closer, their spacing is less than the width of the paper cover, allowing the paper cover to be supported. When the carrier strips move further apart, their spacing is greater than the width of the paper cover, allowing the paper cover to detach from the carrier strips and fall onto the conveyor belt. In this embodiment, the same carrier strip is engaged with multiple sequentially arranged switching cylinders, which work together to drive it, ensuring operational stability. Simultaneously, the forming base plate and forming pressure plate have multiple die-cutting stations, allowing multiple paper covers to be formed simultaneously, thus improving processing efficiency.

[0038] The conveyor belt is made of anti-slip and wear-resistant material, and its operating speed matches the rhythm of the die-cutting and forming components and the carrier switching components, ensuring that the cardboard can be conveyed smoothly and quickly. At the same time, a correction device is installed on the side of the conveyor belt. If a product position deviation is detected during the conveying process, the correction device on the side of the conveyor belt will be automatically activated to adjust the position of the paper cover, ensuring the accuracy of the conveying process.

[0039] In this embodiment, the piston rods of each switching cylinder face opposite directions, and their ends are fixedly installed in the inner support frame. The cylinder body of the switching cylinder engages with the support plate strip, allowing it to move on the piston rod and causing the support plate strips to move closer or further apart. Since the installation space within the inner support frame is small, the installation space for the piston rod is smaller than the installation space for the cylinder body. Using a fixed piston rod and movable cylinder body installation method reduces space occupation. During installation, the air passage interface must use a rotary joint to prevent the air pipe from tangling or breaking during cylinder movement. An additional guide rod can also be added to distribute the lateral force on the cylinder body.
