Description

Technical Field

[0001] This utility model relates to a loading and unloading system, specifically a continuous loading and unloading system for a die-cutting machine, belonging to the field of die-cutting loading and unloading technology. Background Technology

[0002] A die-cutting machine is a post-printing processing machine primarily used for die-cutting, creasing, hot stamping, laminating, and automatic waste removal of non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic components, and mobile phone pads. The die-cutting machine utilizes steel blades, metal molds, and steel wire (or a template engraved from a steel plate) to apply pressure through an imprinting plate, cutting printed materials or cardboard into specific shapes. Depending on the processing requirements, a die-cutting machine can perform various processes such as die-cutting, creasing, hot stamping, laminating, and waste removal.

[0003] In the currently common die-cutting machine loading and unloading process, the roll material is first installed on the roll shaft. Then, a take-up shaft is responsible for pulling the entire roll material to the die-cutting machine. In this process, the die-cutting machine's die cuts the roll material. When the roll material is completely used up and needs to be replaced with new material, the operator needs to stop the die-cutting machine and then manually pull the end of the new roll material onto the take-up shaft before restarting. This method of frequently stopping the machine to manually change materials not only greatly prolongs the time required for each material change, but also reduces the effective operating time of the die-cutting machine in the production process, thereby reducing the utilization efficiency of the entire equipment. Therefore, a continuous uninterrupted loading and unloading system for die-cutting machines is proposed. Utility Model Content

[0004] In view of this, the present invention provides a continuous uninterrupted loading and unloading system for a die-cutting machine to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0005] The technical solution of this utility model embodiment is implemented as follows: a continuous uninterrupted loading and unloading system for a die-cutting machine includes two feeding and receiving components and a die-cutting machine body, wherein the two feeding and receiving components are symmetrically located on both sides of the die-cutting machine body;

[0006] The feeding assembly includes a frame, two mounting bases, support rollers, two lifting bases, a drive motor, two conveying rollers, two feeding belts, springs, and two guide columns.

[0007] Two mounting seats are symmetrically fixedly connected to the upper surface of the frame. The support rollers are equidistantly installed on the opposite faces of the two mounting seats. The two conveying rollers are symmetrically installed on the opposite faces of the two lifting seats. The drive motor is installed on one side of one lifting seat. The two feeding belts are symmetrically installed on the outer side walls of the two conveying rollers. The output shaft of the drive motor is fixedly connected to one end of one conveying roller. The lifting seat is slidably connected to the outer side walls of the two guide columns. The spring is sleeved on the outer side walls of the guide columns.

[0008] More preferably, the feeding belt is symmetrically positioned above the conveyor roller.

[0009] More preferably, pressure shafts are installed at equal intervals on the opposite surfaces of the two lifting seats, and the outer side walls of the pressure shafts are attached to the inner bottom walls of the two feeding belts.

[0010] More preferably, the bottom ends of the two guide posts are symmetrically fixedly connected to the upper surface of the mounting base.

[0011] More preferably, the top end of the spring abuts against the top of the guide post, and the bottom end of the spring abuts against the upper surface of the lifting seat.

[0012] More preferably, the frame is internally fixedly connected to a mounting base, and a mounting shaft is installed on one side of the mounting base.

[0013] More preferably, a material roll is mounted on the outer wall of the mounting shaft.

[0014] More preferably, the strip on the material roll is located between the support roller and the feeding belt and is in contact with the support roller and the feeding belt respectively, and the strip on the material roll passes through the die-cutting worktable of the die-cutting machine body.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] This invention uses a drive motor to rotate a conveyor roller, which in turn drives a feeding belt. A spring pushes a lifting seat, which experiences a downward force, enhancing the friction between the feeding belt and the material belt. When changing the material roll, a new roll is installed on the mounting shaft on the right side, and then the material belt is placed between the feeding belt and the support roller. Driven by the drive motor and the feeding belt, the material belt is automatically pulled and fed. Then, the end of the material belt moves into the receiving and feeding assembly on the left side, where it is automatically pulled and unloaded by the drive motor. This reduces the time required for changing the material belt and improves the utilization efficiency of the die-cutting machine.

Detailed Implementation

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1-5As shown, this utility model embodiment provides a continuous non-stop loading and unloading system for a die-cutting machine, including two feeding and receiving components 101 and a die-cutting machine body 31. The two feeding and receiving components 101 are symmetrically located on both sides of the die-cutting machine body 31. Automatic loading and unloading of the material strip can be realized through the two feeding and receiving components 101. The two feeding and receiving components 101 are symmetrically arranged, one for loading the material strip and the other for unloading the material strip.

[0028] The feeding assembly 101 includes a frame 11, two mounting bases 14, support rollers 15, two lifting bases 16, a drive motor 17, two conveying rollers 19, two feeding belts 20, springs 21, and two guide columns 22.

[0029] Two mounting seats 14 are symmetrically fixedly connected to the upper surface of the frame 11. Support rollers 15 are equidistantly installed on the opposite sides of the two mounting seats 14. Two conveying rollers 19 are symmetrically installed on the opposite sides of the two lifting seats 16. A drive motor 17 is installed on one side of one lifting seat 16. Two feeding belts 20 are symmetrically installed on the outer side walls of the two conveying rollers 19. The output shaft of the drive motor 17 is fixedly connected to one end of one conveying roller 19. The feeding belts 20 are symmetrically located above the conveying rollers 19. The drive motor 17 drives one conveying roller 19 to rotate, and the conveying roller 19 drives the feeding belts 20 to rotate. When the material belt is between the feeding belts 20 and the support rollers 15, the feeding belts 20 can drive the material belt when rotating, thereby realizing the feeding of the material belt.

[0030] The lifting seat 16 is slidably connected to the outer side wall of the two guide columns 22, and the spring 21 is sleeved on the outer side wall of the guide column 22. The lifting seat 16 adopts a lifting design, which can make the feeding belt 20 press the material belt, increase the friction between the material belt and the feeding belt 20, and avoid slippage during the conveying process.

[0031] A fixed base 12 is fixedly connected inside the frame 11. An installation shaft 13 is installed on one side of the fixed base 12. A material roll 32 is installed on the outer side wall of the installation shaft 13. The material strip on the material roll 32 is located between the support roller 15 and the feeding belt 20 and is in contact with the support roller 15 and the feeding belt 20 respectively. The material strip on the material roll 32 passes through the die-cutting worktable of the die-cutting machine body 31.

[0032] During operation, the feeding and receiving components 101 on the left and right sides of the die-cutting machine body 31 work simultaneously. The drive motor 17 drives the conveyor roller 19 to rotate, and the conveyor roller 19 drives the feeding belt 20 to rotate. At this time, the feeding and receiving component 101 on the right side pulls the material belt out from the material roll 32. The material belt passes through the die-cutting machine body 31, and the die-cutting machine body 31 performs die-cutting on the material belt. Then, the feeding and receiving component 101 on the left side winds the die-cut material belt onto the material roll 32 on the left side.

[0033] When changing the material roll 32, simply place the material strip between the feeding belt 20 and the support roller 15. Under the action of the drive motor 17, the material strip can be automatically pulled and fed. Then, the end of the material strip moves into the take-up and feed assembly 101 on the left. Under the action of the drive motor 17, the material strip can be automatically pulled and unloaded. A take-up motor connected to the mounting shaft 13 is installed on the fixed seat 12 on the left to realize the winding of the material strip.

[0034] In one embodiment, two lifting seats 16 are equidistantly mounted with pressing shafts 18 on their opposite faces. The outer wall of the pressing shaft 18 is attached to the inner bottom wall of the two feeding belts 20. The pressing shaft 18 can limit the position of the feeding belts 20 so that the feeding belts 20 can remain attached to the material belt.

[0035] In one embodiment, the bottom ends of the two guide posts 22 are symmetrically fixed to the upper surface of the mounting base 14, the top end of the spring 21 presses against the top of the guide post 22, and the bottom end of the spring 21 presses against the upper surface of the lifting seat 16. The lifting seat 16 is pushed by the spring 21, and the lifting seat 16 drives the conveying roller 19, thereby increasing the friction between the feeding belt 20 and the material belt.

[0036] When this utility model is in operation: the feeding and receiving components 101 on the left and right sides of the die-cutting machine body 31 work simultaneously. The drive motor 17 drives the conveyor roller 19 to rotate, and the conveyor roller 19 drives the feeding belt 20 to rotate. At this time, the feeding and receiving component 101 on the right side pulls the material belt out from the material roll 32. The material belt passes through the die-cutting machine body 31, and the die-cutting machine body 31 performs die-cutting on the material belt. The feeding and receiving component 101 on the left side winds the die-cut material belt onto the material roll 32 on the left side.

[0037] When changing the material roll 32, install the new material roll 32 on the mounting shaft 13 on the right side, then manually pull out the end of the material belt and place the end of the material belt between the feeding belt 20 and the support roller 15. Driven by the drive motor 17 and the feeding belt 20, the feeding belt 20 pulls the material belt. After the material belt moves out from the right-side take-up and feed assembly 101, similarly, manually move the end of the material belt into the left-side take-up and feed assembly 101. Under the action of the drive motor 17, the material belt can be automatically pulled and fed. During use, regularly lubricate and maintain the drive motor 17, the conveyor roller 19 and other components, check the wear of the feeding belt 20, and replace the severely worn feeding belt 20 in time. When the material belt slips, it can be eliminated by adjusting the pressure of the spring 21 or by checking whether there are foreign objects on the surface of the feeding belt 20.

[0038] Compared with the existing technology, this utility model can realize automatic traction and feeding of the material belt through the cooperation of the drive motor 17, the feeding belt 20 and other structures, which effectively improves production efficiency.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
