Description

Technical Field

[0001] This invention relates to the field of feeding equipment technology, specifically to a high-efficiency feeding device for a punching machine that does not require knife marks. Background Technology

[0002] A die-cutting device is a type of die for stamping products. For example, when printing a box, it is a flat piece of paper. After printing, to make it into a box, a flat die with the same shape as the box is needed to stamp it. This die is called a printing die, which can also be simply called a die or a stamping die. A die-cutting device is needed to process printing dies.

[0003] Existing die-cutting machines require manual loading of materials when processing products. The materials are transported to the processing position of the die-cutting machine and then punched. Manual loading is time-consuming and labor-intensive. For some heavy products, manual loading is difficult, which greatly increases the labor intensity of workers and results in low processing efficiency.

[0004] Based on this, we propose a high-efficiency feeding device for a die-cutting machine that does not require knife marks. Summary of the Invention

[0009] Preferably, springs are fixedly connected to the inner walls of both grooves, and the other end of each spring is fixedly connected to the side wall of the vertical rod.

[0010] Preferably, a cleaning mechanism is installed on the U-shaped frame. The cleaning mechanism includes a cleaning box fixedly connected to the upper end of the U-shaped frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) The high-efficiency feeding device of the non-knife-mark processing punching machine is set with a rotating shaft, conveying roller, conveyor belt and first drive mechanism. By driving the first motor to rotate, the conveying roller rotates, and then the conveyor belt moves horizontally to feed the product material. All of them are mechanical structures, which are simple to operate, save time and effort, greatly reduce the labor intensity of workers and improve the feeding efficiency.

[0017] (2) The high-efficiency feeding device of the non-knife-mark processing punching machine can protect the product material on the conveyor belt by setting side plates, so as to prevent the product material on the conveyor belt from deviating and falling off the conveyor belt, thus causing damage to the product material.

[0018] (3) The high-efficiency feeding device of the punching machine without knife marks is equipped with a straightening mechanism. By driving the second motor to rotate, the two rollers move closer to each other to straighten the product material on the conveyor belt, so as to avoid the product material from contacting and rubbing against the side wall for a long time, which would damage the product material.

[0019] (4) By setting up a cleaning mechanism and a third drive mechanism, the dirt on the surface of the conveyor belt can be cleaned while the product material is being transported, keeping the conveyor belt clean and preventing the dirt on the conveyor belt from contaminating the product material and affecting the processing of the product material.

[0020] (5) By setting up a drying mechanism, the residual moisture on the surface of the conveyor belt due to cleaning can be dried, avoiding the residual moisture from wetting certain materials that cannot be exposed to water, which would damage the materials and cause certain losses.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-4 This invention provides a technical solution: a high-efficiency feeding device for a die-cutting machine, comprising a base 1, with support columns symmetrically fixedly connected to the lower end of the base 1, and the lower ends of the support columns being fixedly connected to the ground via expansion joints; four mounting plates symmetrically fixedly connected to the upper end of the base 1; two mounting plates 2 on the same side are rotatably connected to a rotating shaft 3 via their adjacent sidewalls; conveyor rollers 4 are fixedly connected to the sidewalls of the rotating shaft 3; the conveyor rollers 4 are connected to each other via a conveyor belt 5; and side plates 6 are fixedly connected to the upper ends of two mounting plates 2 on the same side; and the base 1 is equipped with... There is a straightening mechanism, which includes a U-shaped frame 7 fixedly connected to the upper end of the base 1. A sliding groove 8 is opened at the top of the U-shaped frame 7. Two sliders 9 are symmetrically fixedly connected to the inner wall of the sliding groove 8. Two grooves 10 are opened at the lower end of each slider 9. Two vertical rods 11 are slidably connected to the inner wall of the two grooves 10. The grooves 10 are T-shaped and the vertical rods 11 are T-shaped. Two horizontal plates 12 are symmetrically fixedly connected to the side walls of the two vertical rods 11 that are close to each other. The two horizontal plates 12 are rotatably connected to a rotating rod 13 that are close to each other. Rollers 14 are fixedly connected to the side walls of the rotating rod 13.

[0031] It should be noted that when the two rollers 14 approach each other to straighten the product material, the two rollers 14 contact the side wall of the product material and the rollers 14 will rotate continuously, changing the sliding friction between the rollers 14 and the product material into rolling friction, thereby reducing the friction between the rollers 14 and the product material and reducing the wear of the product material.

[0032] One of the mounting plates 2 is equipped with a first drive mechanism. The first drive mechanism includes a first motor 15 fixedly connected to the side wall of one of the mounting plates 2 by a bracket. The output end of the first motor 15 passes through the side wall of the mounting plate 2 and is fixedly connected to the rotating shaft 3. A drive wheel 16 is fixedly connected to the side wall of the output end of the first motor 15. One end of the other rotating shaft 3 passes through the side wall of the mounting plate 2 and is fixedly connected to a first driven wheel 17.

[0033] A second drive mechanism is installed inside the slide groove 8. The second drive mechanism includes a bidirectional lead screw 18 rotatably connected inside the slide groove 8. The side wall of the bidirectional lead screw 18 is threadedly connected to two sliders 9. It should be noted that the side walls of the two sliders 9 abut against the inner wall of the slide groove 8, so that the two sliders 9 will not rotate. A second motor 19 is fixedly connected to the side wall of the U-shaped frame 7. The output end of the second motor 19 passes through the side wall of the U-shaped frame 7 and is fixedly connected to the bidirectional lead screw 18.

[0034] Springs 20 are fixedly connected to the inner walls of both grooves 10. The other end of the springs 20 is fixedly connected to the side wall of the vertical rod 11. It should be noted that when the two rollers 14 approach each other to straighten the product material, the vertical rod 11 will slide in the groove 10, which will compress the springs 20. The springs 20 can provide cushioning to prevent the surface of the product material from being suddenly subjected to force, which would damage the product material.

[0035] A cleaning mechanism is installed on the U-shaped frame 7. The cleaning mechanism includes a cleaning box 21 fixedly connected to the upper end of the U-shaped frame 7. A sliding plug 22 is slidably connected to the inner wall of the cleaning box 21, dividing the interior of the cleaning box 21 into two parts: a water pump chamber 221 and a gas pump chamber 222. A water storage tank 23 is fixedly connected to the upper end of the cleaning box 21. A water inlet is opened at the upper end of the water storage tank 23, through which water can be added to the water storage tank 23. A working plate 24 is fixedly connected to the upper end of the base 1 through a fixed shaft. A water inlet groove 25 is opened in the working plate 24. Multiple water spray holes 26 are opened on the inner wall of the water inlet groove 25. A brush bristle 27 is fixedly connected to the upper end of the working plate 24. The brush bristle 27 is fitted to the lower end of the conveyor belt 5. The water pump chamber 221 is connected to the water storage tank 23 through a water inlet pipe 28, and the water pump chamber 221 is connected to the water inlet groove 25 through a water outlet pipe 29.

[0036] A drying mechanism is installed inside the air pump chamber 222. The drying mechanism includes an electric heating plate 30 fixedly connected to the inner wall of the air pump chamber 222. The electric heating plate 30 is electrically connected to the first motor 15. An air inlet groove 31 is opened in the working plate 24. Multiple air jet holes 32 are opened on the inner wall of the air inlet groove 31. An air inlet pipe 33 is fixedly connected to the side wall of the air pump chamber 222. The air pump chamber 222 is connected to the air inlet groove 31 through the air outlet pipe 34.

[0037] One-way valves are installed on the inner walls of the water inlet pipe 28, water outlet pipe 29, air inlet pipe 33, and air outlet pipe 34. It should be noted that the one-way valve installed on the inner wall of the water inlet pipe 28 only allows water in the water storage tank 23 to enter the pump water chamber 221, the one-way valve installed on the inner wall of the water outlet pipe 29 only allows water in the pump water chamber 221 to enter the water inlet tank 25, the one-way valve installed on the inner wall of the air inlet pipe 33 only allows outside air to enter the air pump chamber 222, and the one-way valve installed on the inner wall of the air outlet pipe 34 only allows air in the air pump chamber 222 to enter the air inlet tank 31.

[0038] A third drive mechanism is installed inside the cleaning tank 21. The third drive mechanism includes a movable block 35 that is slidably connected to the inner wall of the cleaning tank 21. Two push rods 36 are symmetrically fixedly connected to the side wall of the movable block 35 near the slide plug 22. The other end of each push rod 36 is fixedly connected to the side wall of the slide plug 22. A reciprocating screw 37 is rotatably connected to the inner wall of the cleaning tank 21. The side wall of the reciprocating screw 37 is threadedly connected to the movable block 35. It should be noted that the side wall of the movable block 35 abuts against the inner wall of the cleaning tank 21, so that the movable block 35 will not rotate. One end of the reciprocating screw 37 passes through the side wall of the cleaning tank 21 and is fixedly connected to a second driven wheel 38. The driving wheel 16, the first driven wheel 17, and the second driven wheel 38 are connected by a synchronous belt.

[0039] It should be noted that the diameter of the second driven wheel 38 is much smaller than that of the driving wheel 16, which makes the rotational speed of the second driven wheel 38 much greater than that of the driving wheel 16. The speed at which the first motor 15 drives the conveyor belt 5 to move horizontally and transport the product materials is relatively slow. However, the second driven wheel 38 can drive the reciprocating screw 37 to rotate rapidly, which in turn drives the sliding plug 22 to slide rapidly on the inner wall of the cleaning tank 21. This allows for rapid pumping of water and air to clean and dry the conveyor belt 5.

[0040] In this invention, the product material is first placed on the conveyor belt 5, then the first motor 15 is powered on to drive it to rotate, and at the same time the electric heating plate 30 is powered on. The rotation of the first motor 15 will drive one of the rotating shafts 3 to rotate, and the first motor 15 will simultaneously drive the drive wheel 16 to rotate, drive the first driven wheel 17 to rotate, and then drive the other rotating shaft 3 to rotate, drive the two conveyor rollers 4 to rotate synchronously, drive the conveyor belt 5 to move horizontally, and then drive the product material to move horizontally, thus conveying and feeding the product material.

[0041] When the product material on the conveyor belt 5 deviates and comes into contact with the side plate 6, the second motor 19 is driven to rotate, which in turn drives the bidirectional lead screw 18 to rotate. This causes the two sliders 9 to slide closer to each other on the inner wall of the chute 8, which in turn drives the two vertical rods 11 to move closer to each other and the two rollers 14 to move closer to each other. When the two rollers 14 come into contact with the side wall of the product, they will straighten the product material, so that the product material is located in the center of the conveyor belt 5 under the action of the rollers 14. This prevents the deviated product material from coming into contact with the side plate 6 for a long time, which would cause the product material to wear.

[0042] When the drive wheel 16 rotates under the drive of the first motor 15, it will synchronously drive the second driven wheel 38 to rotate, drive the reciprocating screw 37 to rotate, and then drive the moving block 35 to slide back and forth on the inner wall of the cleaning tank 21. The moving block 35 drives the sliding plug 22 to slide back and forth on the inner wall of the cleaning tank 21 through two push rods 36. Under the action of the sliding plug 22, the water in the water storage tank 23 will be sucked into the pump water chamber 221 through the water inlet pipe 28. Then the water in the pump water chamber 221 will be squeezed into the water inlet trough 25 through the water outlet pipe 29. Finally, the water in the water inlet trough 25 will be sprayed out through multiple water spray holes 26 to wash the conveyor belt 5. The sprayed water will also wet the brush bristles 27, and the brush bristles 27 will clean the dirt on the surface of the conveyor belt 5.

[0043] Furthermore, when the sliding plug 22 slides and seals against the inner wall of the cleaning chamber 21, it simultaneously draws outside air into the air pump chamber 222 through the air inlet pipe 33. The electric heating plate 30 heats the air entering the air pump chamber 222. Then, the hot air in the air pump chamber 222 is squeezed into the air inlet groove 31 through the air outlet pipe 34. Finally, the hot air is sprayed out from multiple jet holes 32 to dry the residual moisture on the surface of the conveyor belt 5 after cleaning, preventing residual moisture from causing some water-sensitive product materials to become damp and damage the product materials.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
