Description

Technical Field

[0001] This invention relates to the field of mold feeding technology, and in particular to an automatic feeding and conveying device for shaping molds. Background Technology

[0002] Currently, the feeding and conveying of molds in the cigarette box printing industry still largely relies on manual operation. Manual feeding is not only inefficient but also fails to meet the demands of rapidly changing production. Even though some companies have introduced automated feeding and conveying devices, existing equipment has significant drawbacks: the connection between the moving plate and the drive unit in automated equipment is unstable, easily loosening during frequent mold changes; the positioning and adsorption functions of the feeding structure lack precision, and the vibrations generated during operation cause the molds to easily fall or shift during gripping and conveying, compromising the continuity and stability of cigarette box printing. Furthermore, cigarette box molds come in various sizes and specifications, and existing conveying components struggle to provide effective support for molds of different shapes and sizes. This is especially true for irregularly shaped or ultra-thin cigarette box molds, which are prone to tilting and slipping during conveying, severely restricting production efficiency and product quality in cigarette box printing. Therefore, it is urgent to develop an automatic and stable feeding and conveying device for shaping molds that meets the needs of the cigarette box printing industry. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic feeding and conveying device for shaping molds, which aims to solve the problems of insufficiently stable connection and easy drop or displacement of the molds during gripping and conveying of the above-mentioned automatic feeding and conveying devices for cigarette box shaping molds.

[0004] To achieve the above objectives, the present invention provides an automatic feeding and conveying device for shaping molds, comprising an automatic feeding component and a conveying component. The automatic feeding component is used to convey the shaping mold to the conveying component, and the conveying component is used to convey the shaping mold to the next workstation. The automatic feeding component includes a feeding structure and a feeding structure. The feeding structure includes a feeding drive device and a movable plate connected to the drive device. The movable plate is connected to the feeding drive device via a snap-fit ​​structure. The feeding structure includes a first feeding drive device, a feeding plate connected to the first feeding drive device, a second feeding drive device, and an adsorption plate connected to the second feeding drive device. The feeding plate is located at the end of the stroke of the movable plate. The first feeding drive device drives the feeding plate to move up and down, and the highest point of the feeding plate's stroke is flush with the adsorption plate. The second feeding drive device drives the adsorption plate to move horizontally. A micro-rotation device is provided below the feeding plate. The micro-rotation device includes a rotating cylinder and a rotating shaft. The rotating shaft extends laterally through the bottom of the feeding plate. One end of the rotating cylinder is connected to the rotating shaft, and the other end is connected to an eccentric lug at the bottom of the feeding plate. After the shaping mold is pushed onto the feeding plate by the movable plate, the rotating cylinder drives the feeding plate to rotate around the axis to the inside of the feeding plate, so that the stack of shaping molds fits against the long side of the feeding plate; when the feeding plate rises to be flush with the adsorption plate and connects with the shaping mold, the output end of the rotating cylinder retracts, driving the feeding plate to return to the horizontal state. The adsorption plate is equipped with a suction head that matches the mold contour, and the suction head is tightly adsorbed to the surface of the shaping mold; The conveying assembly includes a conveyor belt structure, a support roller disposed in the middle of the conveyor belt structure, and auxiliary support rollers located on both sides of the support roller.

[0005] Preferably, the locking quick-connect structure includes a T-shaped slot on the feeding drive device and a T-shaped plug at the end of the movable plate. The T-shaped plug is provided with a latch that can rotate 90°. The end of the latch is provided with a protrusion. The inner wall of the T-shaped slot is provided with a groove at the corresponding position. When the T-shaped plug is inserted into the T-shaped slot, the latch is rotated to make the protrusion embed into the groove.

[0006] Preferably, the connection between the first feeding drive device and the feeding plate is provided with a floating connection structure.

[0007] Preferably, the first feeding drive device includes a fixed frame, a feeding drive motor, a ball screw, and a drive arm. The fixed frame is symmetrically arranged on both sides of the feeding plate. The feeding drive motor is fixed on the top of the fixed frame, and its output shaft is connected to the ball screw. The nut seat on the ball screw is fixed to the top of the drive arm. The drive arm is connected to the feeding plate through a floating connection structure. The rotating shaft passes through the bottom of the feeding plate and its two ends are connected to the inner side of the drive arm.

[0008] Preferably, the floating connection structure includes a spherical joint disposed on the drive arm and a ball socket connecting seat disposed at the corresponding position on the loading plate, with two tension springs symmetrically installed between the spherical joint and the ball socket connecting seat.

[0009] Preferably, the feeding plate has an L-shaped structure, with a strip groove on the surface of the horizontal section, and a transition roller shaft that is movably connected is installed in the strip groove; a spring buffer is provided on the side of the movable plate near the forming mold.

[0010] Preferably, a rubber shock-absorbing pad is provided between the feeding plate and the eccentric ear plate.

[0011] Preferably, the adsorption plate includes a hollow aluminum alloy plate and a silicone plug. The hollow aluminum alloy plate has an air cavity inside and an array of air holes on one side. The air holes that contact the mold are sealed and connected by the suction head, and the remaining air holes are sealed by the silicone plug.

[0012] Preferably, the auxiliary support rollers are symmetrically positioned between two adjacent support rollers, and both ends of the auxiliary support rollers are connected to the sliding seat. The bottom of the sliding seat is provided with a slider that slides in cooperation with the guide rail on the conveyor belt structure. An elastic element is connected to one side of the sliding seat to drive the auxiliary support rollers to float up and down in a direction perpendicular to the conveyor belt. The surface of the auxiliary support rollers is covered with an elastic layer. The beneficial effects of this invention are: 1. This invention achieves an automated process for shaping molds from feeding and conveying by setting up automatic feeding and conveying components, thereby reducing manual intervention and improving production efficiency.

[0013] 2. This invention utilizes a snap-fit ​​quick-connect structure to connect the movable plate and the feeding drive device in the feeding structure, and incorporates a rubber buffer pad. This facilitates quick disassembly and maintenance of the movable plate, and the rubber buffer pad effectively absorbs vibrations, enhancing connection stability. The shock-absorbing structure and floating connection structure reduce vibrations during the upward movement of the first feeding drive device, ensuring the stability of the adsorption plate's adsorption of the mold. The suction head on the adsorption plate is connected to the mold, ensuring accurate and stable gripping and conveying of the mold. The supporting rollers of the conveying component provide support for the mold, ensuring smooth movement of the mold on the conveyor belt.

[0014] 3. The micro-rotation device of this invention drives the feeding plate to rotate at a small angle. The stacked molds naturally conform to the long side of the feeding plate due to their own weight, forming a self-constrained state. This prevents tipping without external clamping and ensures stacking stability. The rubber shock-absorbing pad absorbs high-frequency, small-amplitude vibrations, reducing the transmission of vibrations from the driving device to the feeding plate and ensuring smooth mold lifting and lowering.

Detailed Implementation

[0028] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0029] like Figures 1-2 As shown, this embodiment provides an automatic feeding and conveying device for shaping molds, including an automatic feeding component and a conveying component 3. The automatic feeding component is used to convey stacks of shaping molds from the feeding position to the conveying component 3, and includes a feeding structure 1 and a feeding structure 2.

[0030] Specifically, the feeding structure 1 includes a feeding drive device 10 (in this embodiment, a drive motor + synchronous belt drive) and a movable plate 12, which are connected by a locking quick-connect structure 13. The feeding drive device 10 is fixed on the equipment frame and consists of a drive motor and a slider rail mechanism. The drive motor is selected according to the weight, size, and pushing speed requirements of the cigarette box mold to ensure sufficient power. The slider rail mechanism provides support for the movement of the movable plate 12 and reduces resistance. The drive motor drives the movable plate 12 to push the shaping mold to the feeding structure 2.

[0031] The locking quick-connect structure 13 between the movable plate 12 and the feeding drive device 10, specifically, is as follows: Figure 3 As shown, the output end of the feeding drive device 10 is provided with a T-shaped slot 131, and the end of the movable plate 12 near the drive device is provided with a T-shaped insert 132 that matches the slot. The two are shaped to match, and the T-shaped insert 132 has symmetrically arranged latches 133 that can rotate 90° on both sides. The latches 133 have an integrally formed protrusion at their ends, and the inner wall of the T-shaped slot 131 has a corresponding groove that matches the protrusion. When the T-shaped insert 132 is inserted into the T-shaped slot 131, rotating the latches 133 causes the protrusion to embed into the groove, achieving quick locking between the movable plate 12 and the drive device. Furthermore, a rubber buffer pad is attached to the contact area between the latches 133 and the T-shaped slot 131, utilizing its good elasticity, wear resistance, and aging resistance to absorb high-frequency vibrations and impacts during the feeding process. When it is necessary to push the mold, the drive motor starts, driving the slider to move linearly on the slide rail through the transmission mechanism, thereby pushing the movable plate 12 to advance the arranged cigarette box molds row by row. Thanks to the snap-lock quick-connect structure 13, when the cigarette box mold needs to be replaced due to design updates, the snap-lock 133 can be quickly rotated to unlock and replace the movable plate 12, adapting to molds of different specifications. This solves the problems of easy loosening and low efficiency when replacing molds using traditional connection methods. The rubber buffer pad effectively absorbs vibration, enhances connection stability, prevents the movable plate 12 from loosening during feeding, ensures accurate mold feeding position, and lays the foundation for subsequent printing processes.

[0032] Furthermore, such as Figure 4 As shown, the feeding structure 1 (i.e., the side of the movable plate 12 facing the mold) is equipped with a spring buffer, which consists of a spring and a buffer plate. When the movable plate 12 pushes the mold, the buffer plate contacts the mold first, and the spring is compressed to absorb the kinetic energy of the mold. This reduces the impact force on the mold to a level that does not affect its positioning on the loading plate 21, allowing the mold to enter the loading plate 21 smoothly and slowly, improving positioning accuracy and preventing the mold position from shifting due to excessive impact force.

[0033] like Figure 5As shown, the first feeding drive device 20 is located on both sides of the feeding plate 21, and consists of a fixed frame 201, a feeding drive motor 202, a ball screw 203, and a drive arm 204. The fixed frame 201 is fixedly installed on the equipment frame, providing stable support for the drive device. The feeding drive motor 202 is connected to the fixed frame 201, and the motor output end is connected to the ball screw 203 through a coupling. The ball screw 203 is fixedly connected to one end of the drive arm 204, and the drive arm 204 is connected to the feeding plate 21 to achieve precise lifting and lowering control of the feeding plate 21. Specifically, the feeding plate 21 is located at the end of the stroke of the movable plate 12, and the feeding drive motor 202 drives the feeding plate 21 to move up and down, with the highest point of the feeding plate 21 flush with the adsorption plate 23.

[0034] Furthermore, the loading plate 21 is L-shaped, with horizontal and vertical sections forming the mold positioning space (the horizontal section is used to support the mold, and the vertical section is used for limiting movement). For example... Figure 6 As shown, the horizontal section of the feeding plate 21 has a strip groove 211 machined on its surface. Multiple adjustable transition rollers 212 are installed within the strip groove 211 and are bolted to the outermost edge of the horizontal section of the feeding plate 21. Operators can adjust the size of the transition rollers 212 according to the actual specifications of the cigarette box mold, making it easier for the mold to enter the feeding plate 21, reducing friction, and preventing the mold from tilting due to friction during movement.

[0035] Furthermore, such as Figure 7 As shown, a rubber shock-absorbing pad is provided at the connection between the first feeding drive device 20 and the feeding plate 21. The rubber shock-absorbing pad 251 is a multi-layer stacked structure, with each layer being 5-8mm thick. The layers are bonded together with strong adhesive and laid between the eccentric ear plate 243 and the feeding plate 21 to withstand low-frequency impact forces (such as vibrations caused by gaps in the installation between structures or slight friction caused by component movement).

[0036] In the floating connection structure 26 of this application, the spherical joint 261 is installed at the drive arm 204, and the ball-and-socket connector 262 is set at the corresponding position on the feed plate 21, with a slight gap between them. Tension springs 263 are installed on both sides of the ball-and-socket connector 262 to adjust the tightness of the connection between the ball-and-socket connector 262 and the spherical joint 261, ensuring that the spherical joint 261 and the ball-and-socket connector 262 are in a fixed connection (the feed plate 21 does not automatically tilt under normal conditions) and that the feed plate 21 can rotate when it rotates slightly.

[0037] During operation, the feeding drive motor 202 rotates, driving the ball screw 203 to rotate, which in turn moves the drive arm 204 up and down via the nut pair, achieving precise lifting and lowering of the feeding plate 21. After the feeding structure 1 pushes the mold into the feeding plate 21, the adjustable transition roller 212 precisely transitions the mold. During the process of the first feeding drive device 20 driving the feeding plate 21 to rise, the rubber shock-absorbing pad 251 absorbs low-frequency vibrations; the floating connection structure 26 allows the feeding plate 21 to swing and shift slightly in three-dimensional space, adaptively adjusting the positional changes caused by vibrations, and the tension spring 263 keeps it stable during vibrations. Thus, the impact of vibration on mold adsorption is effectively reduced, ensuring mold adsorption stability and positioning accuracy, meeting the high-precision requirements of cigarette box printing.

[0038] For further details, please refer to [link / reference]. Figures 6-7 A micro-rotation device 24 is provided below the loading plate 21 to drive the loading plate 21 to rotate at a small angle to stabilize the stacked molds. It includes a rotating cylinder 241 and a rotating shaft 242. The rotating shaft 242 passes through the rear part of the bottom of the loading plate 21 laterally, and both ends are installed on the inner side of the drive arm 204 through bearing seats to ensure smooth rotation. One end of the cylinder body of the rotating cylinder 241 is fixed to the lower part of the drive arm 204, and the output end is connected to the eccentric ear plate 243 at the front of the bottom of the loading plate 21. After the movable plate 12 pushes the stack of molds onto the loading plate 21, the piston rod of the rotating cylinder 241 extends, driving the loading plate 21 to rotate slightly around the rotating shaft 242 towards the inner side of the loading plate 21 (e.g., 1~3°, the angle can be adjusted by the cylinder stroke). The stack of molds adheres to the long side (L-shaped vertical section) of the loading plate 21 due to their own weight, preventing them from tipping over. When the loading plate 21 rises to the position flush with the adsorption plate 23, the piston rod of the rotating cylinder 241 retracts, driving the loading plate 21 back to the horizontal state.

[0039] like Figures 8-9As shown, the second feeding drive device 22 (this application uses a cylinder or motor; this structure is an existing design and is only shown in the figure for illustration, so it will not be described in detail here) is installed on the equipment frame and connected to the adsorption plate 23 via a fixed connector. The adsorption plate 23 includes a hollow aluminum alloy plate 231. One side of the hollow aluminum alloy plate 231 is fixed to the second feeding drive device 22, and an air cavity is machined inside the plate. An array of air holes is opened on the other side. The layout and number of air holes are designed according to the shape, size, and center of gravity distribution of common cigarette box molds. Each air hole corresponds to a suction head 232, which is a conical rubber suction cup. The suction head 232 is sealed to the air hole in contact with the mold, and silicone plugs 233 are used to seal the air holes that do not correspond to each other. When the first feeding drive device 20 raises the feeding plate 21 (which drives a row of positioning molds to rise) to be flush with the adsorption plate 23, the second feeding drive device 22 drives the adsorption plate 23 to move to the feeding plate 21, so that the suction head 232 is in close contact with the mold surface. The vacuum system evacuates the hollow aluminum alloy plate 231, creating a negative pressure between the suction head 232 and the mold, generating sufficient adsorption force to firmly adsorb the mold onto the suction head 232. Subsequently, the second feeding drive device 22 drives the adsorption plate 23 to move, accurately transferring the mold to the conveying assembly 3. This design ensures that the suction head 232 and the mold form a good seal and adsorption, realizing reliable mold gripping and conveying, and preventing the mold from falling or shifting.

[0040] like Figures 10-11 As shown, the conveying assembly 3 includes a conveyor belt structure 30 and a support roller 31 disposed in the middle of the conveyor belt structure 30, with auxiliary support rollers 32 on both sides of the support roller 31. The conveyor belt structure 30 of the conveying assembly 3 is a ring belt, driven by a motor to rotate in a circular motion through a pulley. The support roller 31 is disposed in the middle of the conveyor belt structure 30, with its axis perpendicular to the direction of conveyor belt operation, providing basic support. Auxiliary support rollers 32 with adjustable height and spacing are added on both sides of the support roller 31 according to the common size and shape of cigarette box molds, and adjustment is achieved through bolts or a slide rail mechanism.

[0041] Furthermore, auxiliary support rollers 32 are symmetrically positioned between two adjacent support rollers 31. Both ends of the auxiliary support rollers 32 are connected to sliding seats 321. The bottom of the sliding seats 321 is equipped with sliders 322, which slide in cooperation with the guide rails 323 on the conveyor belt structure 30. An elastic element is connected to one side of the sliding seat 321, driving the auxiliary support rollers 32 to float up and down perpendicular to the conveyor belt direction. The surface of the auxiliary support rollers 32 is covered with an elastic layer. When the mold falls onto the conveyor belt, the two auxiliary support rollers 32 move along the guide rails 323 towards the bottom edge of the mold under the action of the elastic element until they contact the bottom surface of the mold. This fills the gap between the two support rollers 31, reducing swaying during conveying (especially when the mold moves between the two support rollers 31).

[0042] During operation, stacks of molds are placed in the automatic feeding assembly. The feeding drive device 10 drives the movable plate 12 forward via the locking quick-connect structure 13. At this time, the mechanical locking of the T-shaped insert 132 and the T-shaped slot 131 ensures a stable connection. The rubber buffer absorbs vibration, and the spring buffer cushions the impact when the movable plate 12 contacts the mold. The transition roller 212 smoothly lowers the mold to the L-shaped horizontal section of the feeding plate 21. After the mold is in place, the micro-rotation device 24 drives the feeding plate 21 to rotate 1°, and the stack of molds fits against the long side of the feeding plate 21 to avoid tipping. The first feeding drive device 20 is activated, and the ball screw 203 drives the feeding plate 21 to rise until it is flush with the adsorption plate 23. The feeding plate 21 returns to horizontal, and the adsorption plate 23 moves to the front of the mold under the drive of the second feeding drive device 22. The suction head 232 adsorbs the mold through negative pressure. After the adsorption is stable, the adsorption plate 23 moves horizontally above the conveying assembly 3 (conveyor belt structure 30) and releases the mold. The mold rests on the support roller 31, and the auxiliary support rollers 32 on both sides adhere to the bottom of the mold under the action of the elastic element 324. The polyurethane elastic layer reduces vibration and finally smoothly conveys it to the next process. The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
