Description

Technical Field

[0001] The invention relates to the field of die-cutting machines, and in particular to a plastic plate die-cutting device which is convenient for orderly collecting waste materials. Background Art

[0002] Die-cutting machines are also called die-cutting machines, cutting machines, and CNC punching machines. They are mainly used for die-cutting (full-cutting, half-cutting), embossing and hot stamping operations, laminating, and automatic waste discharge of some corresponding non-metallic materials, self-adhesive stickers, EVA, double-sided tapes, electronics, mobile phone pads, etc. The die-cutting machine uses steel knives, hardware molds, steel wires (or templates carved from steel plates), and applies a certain pressure through the stamping plate to roll and cut the printed product or cardboard into a certain shape. If the entire printed product is pressed into a single graphic product, it is called die-cutting. If steel wires are used to press marks or leave bent grooves on the printed product, it is called indentation. At present, die-cutting devices are used in the processing of plastic plates for die-cutting operations. When the existing die-cutting devices are used, they do not have a discharge structure for the die-cut products. During the processing process, the products need to be ejected by secondary operations at a later stage, which is inconvenient for product collection, and the secondary operation delays time, affecting the die-cutting efficiency. In order to solve the above-mentioned problems, we propose a plastic plate die-cutting device that is convenient for orderly collection of waste. Summary of the invention

[0003] The purpose of the present invention is to provide a plastic plate die-cutting device which is convenient for orderly collecting waste materials, and the device has the advantages of being able to actively eject and orderly collect products and waste materials.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: A plastic plate die-cutting device that is convenient for orderly collecting waste materials, comprising a processing table, a lower die assembly is installed inside the processing table, an upper die assembly is installed on the top of the processing table, two roller conveying devices are also installed on the top of the processing table, a conveying assembly is installed at the bottom of the processing table, a reeling device and a waste reeling device are respectively installed on one side and the top of the processing table, a pressing assembly is also symmetrically installed on the top of the processing table, and a cutter is provided on the top of the processing table;

[0005] It should be noted that both the unwinding device and the waste winding device include a motor and a roller, the motor is used to drive the roller to rotate, the roller of the unwinding device is used to connect the plastic to be unwound, and the roller of the waste winding device is used to connect the plastic after die-cutting; the unwinding device and the waste winding device are prior art and will not be described in detail here; the unwinding device and the waste winding device are suitable for die-cutting of plastics that are flexible and can be rolled;

[0006] There are two roller conveying devices, which are composed of a motor and a roller. The motor is used to drive the roller to rotate, and the roller is used to contact the plastic. The friction between the roller and the plastic can push the plastic to move. The roller conveying device is a prior art and its principle is not described in detail here.

[0007] The roller conveyor can generate friction with the flexible plastic to push the flexible plastic. It can also be used to push the hard plastic plate that cannot be rolled up.

[0008] The cutter is used for die-cutting hard plastic plates. Its length is greater than the length of the ejector rod. The cutter needs to be used in conjunction with a roller conveyor device. After die-cutting the hard plastic plate, the roller conveyor device can directly push the die-cut plastic plate out of the processing table and onto the conveyor belt connected between conveyor rollers one and two.

[0009] By adopting the above technical scheme, the upper die assembly is set up to complete the pushing out of the product during die cutting, and the use of the conveying assembly can transport the products in an orderly manner, and the product collection box can be used to collect the products in an orderly manner. The waste can be collected in an orderly manner by cooperating with the unwinding device and the waste winding device.

[0010] The present invention is further configured as follows: the lower die assembly comprises a fixed seat, a plurality of die cutters are installed on the top of the fixed seat, and the fixed seat is fixedly installed by screws and a processing table.

[0011] By adopting the above technical solution, a lower die assembly is provided to cooperate with an upper die assembly to cut flexible plastics, and the lower die assembly can also be used for die-cutting of rigid plastic plates.

[0012] The present invention is further configured as follows: the upper die assembly includes a support frame, a cylinder is installed inside the support frame, a connecting plate is installed at the output end of the cylinder, a connecting seat is installed at the bottom of the connecting plate by screws, a plurality of pressing blocks are installed at the bottom of the connecting seat, and one pressing block is corresponding to one die cutter;

[0013] An ejection assembly is provided on the top of the support frame.

[0014] The above technical solution is adopted, through the setting of the upper die assembly, to cooperate with the lower die assembly to die-cut the plastic;

[0015] Specifically, according to the shape that needs to be die-cut, the lower die assembly and the upper die assembly of the corresponding shape are replaced;

[0016] When facing the flexible plastic, the flexible plastic can be unwound by the unwinding device, the flexible plastic passes through the bottom of the two roller conveying devices, and then the flexible plastic is rewound by the waste rewinding device;

[0017] The cylinder pushes the connecting plate down, and the connecting plate drives the connecting seat and the pressing block down. The pressing block presses the plastic down, and the die cutter cuts the plastic. The product enters the die cutter, and the waste is collected by the waste winding device.

[0018] When facing hard plastic sheets, there is no need to use unwinding device and waste rewinding device to rewind the plastic sheets;

[0019] The plastic sheet needs to be pushed to the top of the die-cutting knife through a roller conveyor device, and the cylinder pushes the connecting plate, the connecting seat and the lower pressure block down. By installing the cutter on one side of the connecting plate, after the lower pressure block and the die-cutting knife die-cut the plastic sheet, the length of the cutter is consistent with the length of the lower pressure block. After the lower pressure block and the die-cutting knife complete the die-cutting of the plastic sheet, the cutter will also die-cut the plastic sheet. When the roller conveyor device continues to convey the plastic sheet that has not been die-cut, another roller conveyor device will convey the die-cut plastic sheet to the conveyor belt that is transmission-connected between conveyor roller one and conveyor roller two, and it will be discharged through the conveyor belt. The die-cut plastic sheet can be collected in an orderly manner in conjunction with a receiving box.

[0020] The present invention is further configured as follows: the ejection assembly includes a connecting plate, a plurality of outer rods are fixedly connected inside the connecting plate, a spring 1 is provided inside the outer rod, the top end of the spring 1 is fixedly connected to the outer rod via a spring fixing member, the bottom of the spring 1 is fixedly connected to an ejection rod via a spring fixing member, the ejection rod corresponds to the die cutting knife, and the outer rod is slidably connected to the inside of the connecting plate.

[0021] The above technical solution is adopted to eject the die-cut products or waste materials through the setting of the ejection component;

[0022] The flexible plastic is die-cut between the upper die assembly and the lower die assembly and passes through the top of the ejector assembly to become the product;

[0023] After the hard plastic plate is die-cut between the upper die assembly and the lower die assembly, the waste is ejected by the ejector assembly, and the product is cut by the cutter;

[0024] The ejector assembly works the same whether it is facing hard plastic or flexible plastic;

[0025] Specifically, after the die-cut plastic is in place, the cylinder pushes the connecting plate, the connecting seat and the lower pressure block down, and the ejector rod will first contact the plastic. As the lower pressure block descends, the ejector rod will push spring one upward to squeeze and compress spring one. After the lower pressure block and the die-cutting knife complete die-cutting of the plastic, the die-cut plastic enters the die-cutting knife, and the connection between the cut plastic and the undie-cut plastic is disconnected. The compressed spring one pushes the ejector rod to reset. The ejector rod resets and pushes the plastic inside the die-cutting knife downward to the conveyor belt driven by the conveyor roller four and the conveyor roller three. The plastic is transported by the conveyor belt and can be collected in an orderly manner with a collection box.

[0027] The above technical solution is adopted to convey the plastic pushed out by the ejection component and the material cut by the cutter through the arrangement of the conveying component;

[0028] Two sets of pulleys are installed on the surfaces of the conveyor roller 2 and the conveyor roller 3. The number of pulleys in a set is two, and the two pulleys in a set are connected by belt transmission.

[0029] The conveyor roller 2 is connected to the conveyor motor. When the conveyor motor is started, the conveyor roller 2 can be driven to rotate. The conveyor roller 2 rotates through the pulley on its surface and the pulley on the surface of the belt-driven conveyor roller 3. The conveyor roller 2 rotates through the conveyor belt to drive the conveyor roller 1 to rotate. The conveyor roller 3 rotates through the conveyor belt to drive the conveyor roller 4 to rotate.

[0030] The conveyor belt between the conveyor roller four and the conveyor roller three receives the waste material pushed out by the ejection assembly and directly conveys it to be collected by the collection box;

[0031] The belt between the conveyor roller 2 and the conveyor roller 1 is used to receive the plastic after being die-cut by the cutter and collect it through the collection box.

[0032] The present invention is further configured as follows: the clamping assembly includes a fixed frame, the bottom of the fixed frame is installed with the processing table, a lower pressure rod is installed inside the fixed frame, a lower pressure plate is installed at the output end of the lower pressure rod, and two storage grooves are provided on the top of the processing table, and the storage grooves correspond to the bottom of the lower pressure plate.

[0033] The above technical solution is adopted, through the setting of the clamping assembly, to clamp and fix the plastic when die-cutting the plastic, so as to achieve the purpose of stabilizing the plastic plate;

[0068] Working principle:

[0069] Plastic die-cutting includes flexible plastics that can be rolled up and rigid plastic sheets in the form of long strips or long plates that cannot be rolled up.

[0070] For die-cutting of flexible plastics, it is necessary to install the rolled plastic and the unwinding device 6, and then pass the plastic through the bottom of the roller conveying device 4, between the lower mold assembly 2 and the upper mold assembly 3, and the bottom of another roller conveying device 4, and then install it with the waste winding device 7. The flexible plastic is rolled up by the waste winding device 7. When the flexible plastic is die-cut, the roller conveying device 4 can be rotated to open or close.

[0071] The hard plastic plate does not need to be used with the unwinding device 6 and the waste winding device 7. If width die cutting is required, the cutter 9 and the connecting plate 33 can be installed by screws. If not required, they are not installed.

[0072] By passing the plastic sheet through the bottom of the roller conveyor 4 and generating friction with the rollers of the roller conveyor 4, and then starting the two roller conveyors 4, the roller conveyor 4 that contacts the plastic sheet first can use the friction force to convey the plastic sheet forward to between the lower mold assembly 2 and the upper mold assembly 3;

[0073] Whether it is die cutting of flexible plastic or rigid plastic sheet, the die cutting process is as follows;

[0074] The plastic is between the lower die assembly 2 and the upper die assembly 3, and the cylinder 32 pushes the connecting plate 33, the connecting seat 34, the lower pressure block 35 and the ejection assembly 36 to descend. First, the ejector rod 364 will contact the plastic. When the die cutting is not completed, the hardness of the plastic is enough to lift the ejector rod 364. The ejector rod 364 is squeezed upward and squeezes the spring 1 363 to compress the spring 1 363. As the lower pressure block 35 contacts the plastic, the lower pressure block 35 pushes the plastic downward and is cut by the die cutting knife 22. The product / waste will enter the inside of the die cutting knife 22. At this time, the product / waste loses the connection with the plastic, and the compressed spring 1 363 pushes the ejector rod 364 to rebound and reset. The ejector rod 364 pushes the product / waste downward to pass through the die cutting knife 22 and reach the belt driven by the conveyor roller 4 55 and the conveyor roller 3 54.

[0075] Then the conveying motor 57 starts to drive the conveying roller 2 53 to rotate, and the conveying roller 2 53 drives the conveying roller 1 52 to rotate through the conveying belt, and the conveying belt between the conveying roller 2 53 and the conveying roller 1 52 works;

[0076] When the conveying roller 2 53 rotates, it also drives the two pulleys 56 on its surface to rotate. The two pulleys 56 drive the other two pulleys 56 installed on the conveying roller 3 54 to rotate through the belt. The two pulleys 56 drive the conveying roller 3 54 to rotate. The conveying roller 3 54 then drives the conveying roller 4 55 to rotate through the conveyor belt. At this time, the conveyor belt connected by the conveying roller 3 54 and the conveying roller 4 55 works to transport the product / waste. At the end of the conveyor belt, only a collection box / box needs to be set to collect the product / waste in an orderly manner.

[0077] After die-cutting of the flexible plastic, the waste reeling device 7 works to reel and collect the waste, and the unwinding device 6 unwinds and waits for the next die-cutting;

[0078] After the hard plastic plate is die-cut, another roller conveyor device 4 will push the plastic plate out of the processing table 1 to the conveyor belt between conveyor roller 1 52 and conveyor roller 2 53, and be transported by the conveyor belt; if a cutter 9 is used to die-cut the hard plastic plate into equidistant plates, another roller conveyor device 4 will also push the plastic plate out of the processing table 1 and onto the conveyor belt between conveyor roller 1 52 and conveyor roller 2 53, and it only needs to be matched with a collection box / box for orderly collection.

[0079] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
