DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0022] In the description of the present invention, it should be understood that descriptions involving orientation, such as orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0023] In the description of the present invention, "a number" refers to one or more than one, and "a plurality" refers to two or more than two. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0024] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0025] In the related technology, the traditional processing flow adopts standard die-cutting technology, firstly splicing the outer shape of the release film with the non-glue area (to facilitate the discharge of the waste of the internal frame), and then compounding the foam with the glue layer. In the raw materials, the foam without substrate is directly laid and compounded as a whole. After the full perforation is completed, the waste is discharged from the bottom, and the waste in the middle is discharged from the top. Finally, the paper is pasted and rolled. The waste of the inner frame cannot be used, and the utilization rate of the main material is only 11%.

[0026] Among them, refer to Figure 1 As shown, the waste area 10 is the shaded area in the figure, and the finished product area 20 is the remaining area. The finished product area 20 is basically in the shape of a door frame, and the shaded area within the door frame is the waste area 10. Only the finished product area 20 in the shape of a door frame is the desired product, so that most of the main materials become waste after cutting, and the material utilization rate of the main materials is very low. In addition, in the related art, the foam and the adhesive layer are directly die-cut to form a single finished product after compounding, and at most multiple separate finished products are obtained.

[0027] Reference Figures 2 to 4 As shown, the first embodiment of the present invention provides a method for utilizing waste materials, comprising: S1: The base belt 210 is combined with the first conveyor belt 110, and the conveyor assembly 100 conveys the first conveyor belt 110; S2: Slitting the base tape 210 into a continuous semi-finished tape 220 and a continuous waste tape 230; S3: The waste belt 230 is separated from the semi-finished product belt 220 of the first conveyor belt 110, and the waste belt 230 is combined with the second conveyor belt 440, and the second conveyor belt 440 is rolled up; S4: The conveying assembly 100 conveys the first conveying belt 110 along the conveying direction, and the semi-finished belt 220 is processed into a finished product; S5: The conveying assembly 100 conveys the second conveying belt 440 along the conveying direction, and based on the waste pitch of the waste belt 230 , adjusts the actual pitch of the conveying assembly 100 to be substantially consistent with the pitch of the waste belt 230 .

[0028] In this embodiment, the base belt 210 in S1 refers to: a composite belt of a multi-layer object. Taking a U-shaped substrate-free foam product as an example, the base belt 210 includes a COVER belt, a foam belt and a double-sided tape stacked in sequence, and the side of the COVER belt away from the main material belt 212 is connected to the first conveyor belt 110. It should be noted that COVER is a die-cut product with a specific function and shape, which is mainly used as a cover to seal or lock. The first conveyor belt 110 refers to: a belt with active conveying ability. Generally speaking, the first conveyor belt 110 is a release film, which has low viscosity and can be adhered to the base belt 210 as a whole, and can be quickly separated from the base belt 210 under the action of external force. The first conveyor belt 110 can be combined with the base belt 210 when the base belt 210 needs to be transported to drive the base belt 210 to be transported. After the base belt 210 is processed into a finished product, the finished product can be separated from the first conveyor belt 110 under a certain external force.

[0029] In S2, the base tape 210 is cut by the primary die-cutting assembly 300, and the base tape 210 that has passed through the primary die-cutting assembly 300 is separated into a semi-finished tape 220 and a waste tape 230, and both the semi-finished tape 220 and the waste tape 230 are connected to the base tape 210 that has not passed through the primary die-cutting assembly 300, and after passing through the primary die-cutting assembly 300, the semi-finished tape 220 and the waste tape 230 are separated, but not separated from the base tape 210, so that the semi-finished tape 220 and the waste tape 230 can be connected in the form of tapes and subsequently transported. In this embodiment, the primary die-cutting assembly 300 only cuts to the foam tape, so that part of the foam tape and part of the double-sided tape form waste, and the rest forms a semi-finished product on the first conveyor belt 110.

[0030] In S3, the semi-finished product belt 220 is separated from the scrap belt 230. In the present embodiment, the scrap belt 230 and the semi-finished product belt 220 are separated by a separation roller and a second conveyor belt 440. The surface of the second conveyor belt 440 has a certain viscosity. Under the contact of the separation roller, the second conveyor belt 440 and the scrap belt 230 are adhered to each other, so that the head end of the scrap belt 230 is separated from the semi-finished product belt 220. At the same time, the scrap belt 230 is directly compounded with the surface of the second conveyor belt 440, so that the scrap belt 230 is compounded with the second conveyor belt 440. In addition, the scrap belt 230 is not easy to be offset, and the position accuracy of the scrap belt 230 is higher.

[0031] In S4, the semi-finished product belt 220 is further processed by the first conveyor belt 110. In this embodiment, the semi-finished product has processing requirements such as holes and grooves, and needs to be processed by the secondary die-cutting component 500. In addition, the semi-finished product belt 220 can also be cut into multiple finished products by the secondary die-cutting component 500, so as to separate a single finished product from the first conveyor belt 110. The process of processing the semi-finished product with holes, grooves and other structures and the process of cutting the semi-finished product belt 220 into a single finished product can be processed by the same set of secondary die-cutting components 500, thereby improving the processing efficiency and saving equipment and finished products. Of course, it can also be divided into multiple processes for processing separately.

[0032] In S5, after the first conveyor belt 110 has conveyed the semi-finished product, the first conveyor belt 110 itself has also been unwound. At this time, the reeled second conveyor belt 440 is replaced to the position of the first conveyor belt 110, and the second conveyor belt 440 conveys along the conveying direction of the first conveyor belt 110. The waste belt 230 composited by the second conveyor belt 440 will also move along the moving direction of the semi-finished product belt 220 and be processed. When the waste belt 230 is processed along the processing path of the semi-finished product, if the conveying assembly 100 produces too many semi-finished products, resulting in error accumulation, which in turn causes the conveying assembly 100 to If the pitch of the semi-finished product 100 changes, then, after the scrap tape 230 is processed by the secondary die-cutting component 500, part of the material of the scrap tape 230 will be cut by the secondary die-cutting component 500 due to the change in pitch, and the change in pitch can be judged according to the part of the scrap tape 230 cut by the secondary die-cutting component 500, and then the conveying component 100 is adjusted to calibrate the pitch of the conveying component 100, so that the relative position accuracy of the semi-finished product tape 220 and the secondary die-cutting component 500 in the subsequent production process is higher, and the yield rate of the semi-finished product tape 220 processed into a finished product is higher.

[0033] It is worth understanding that the scrap belt 230 is stored in a composite manner with the second conveyor belt 440, so that the scrap belt 230 can maintain the shape when it is cut. After the semi-finished product is processed into a finished product, the scrap belt 230 is re-conveyed along the conveying direction, and the actual pitch of the conveying component 100 is adjusted by the scrap pitch of the scrap belt 230, so that the actual pitch of the conveying component 100 is consistent with the pitch of the scrap belt 230, thereby eliminating the error between the set pitch and the actual pitch of the conveying component 100, so that the conveying accuracy of the conveying component 100 is higher. At the same time, the scrap belt 230 is used for waste utilization, which greatly improves the material utilization efficiency.

[0034] Reference Figure 2 and Figure 3 As shown, in some specific embodiments of the present invention, S5 includes: S51: adjusting the step distance of the conveying assembly 100 to a set step distance; S52: The conveying assembly 100 conveys the second conveying belt 440 along the conveying direction of the first conveying belt 110 at a set step distance; S53: The pitch detection component detects the pitch of the waste belt 230 of the second conveyor belt 440; S54: The processor compares the pitch of the waste belt 230 with the set pitch, and adjusts the set pitch to be substantially consistent with the pitch of the waste belt 230.

[0035] It should be noted that although the conveying component 100 can be set to a set step distance, due to the accumulation of errors during long-term conveying of the conveying component 100 and the errors that cannot be eliminated, there will be an error between the set step distance and the actual step distance. When the error exceeds the preset error range, the conveying accuracy of the conveying component 100 will decrease, which will lead to an increase in the defective rate.

[0036] In this embodiment, after the first conveyor belt 110 is completed, the operator connects the end of the first conveyor belt 110 with the head end of the second conveyor belt 440, and then continues to start the conveyor assembly 100 for conveying. After the waste belt 230 on the second conveyor belt 440 moves to the preset position, it starts to be conveyed according to the set pitch of the conveyor assembly 100. When the reeled second conveyor belt 440 replaces the original belt roll of the first conveyor belt 110, the conveyor assembly 100 unwinds the second conveyor belt 440 and conveys the second conveyor belt 440 according to the set pitch. Because the notch position of the waste belt 230 corresponds to the position of the semi-finished product belt 220, if the set pitch of the conveyor assembly 100 is consistent with the actual pitch, the secondary die-cutting assembly 500 should directly cut the notch position of the waste belt 230, and will not cut the waste belt 230, and the waste belt 230 can still remain intact after passing through the secondary die-cutting assembly 500. Similarly, if the set pitch of the conveying component 100 is inconsistent with the actual pitch, the secondary die-cutting component 500 will directly cut onto the waste belt 230, causing the waste belt 230 to be defective. The difference and direction between the set pitch and the actual pitch can be determined by the defective position of the waste belt 230, and then adjusted to make the set pitch basically consistent with the actual pitch.

[0037] Specifically, the adjustment method of the set step length and the actual step length is as follows: S541: When the processor detects that the step length of the waste belt 230 is less than the set step length, the processor adjusts the set step length to decrease; when the processor detects that the step length of the waste belt 230 is greater than the set step length, the processor adjusts the set step length to increase.

[0038] Further, S5411: when the processor detects that the step distance of the waste belt 230 is smaller than the set step distance, the processor controls the conveying speed of the conveying component 100 to increase, and the conveying time of the conveying component 100 in each step remains unchanged; when the processor detects that the step distance of the waste belt 230 is greater than the set step distance, the processor controls the conveying speed of the conveying component 100 to decrease, and the conveying time of the conveying component 100 in each step remains unchanged.

[0039] In this embodiment, the conveying speed of the conveying assembly 100 is adjusted, and the conveying time is kept unchanged, and then the set step distance of the conveying assembly 100 is adjusted, so that the set step distance of the conveying assembly 100 can be consistent with the step distance of the waste belt 230. As another implementation, in theory, the conveying speed of the conveying assembly 100 can be kept unchanged, and only the conveying time of the conveying assembly 100 is adjusted, so that the set step distance of the conveying assembly 100 can be consistent with the step distance of the waste belt 230.

[0040] In some specific embodiments of the present invention, the step detection component is a fiber optic tracking device. The processor is a host computer, and a related program is preset in the host computer to perform automatic matching of the set step and the step of the waste belt 230.

[0041] Reference Figure 2 and Figure 3 As shown, in some specific embodiments of the present invention, S1 includes: S11: The substrate belt 211 is laminated to the first conveyor belt 110; S12: The main material strip 212 is compounded with the base material; S13 : The adhesive tape 213 is compounded with the main material to form the base tape 210 .

[0042] In this embodiment, the base material belt 211 is a cover belt, the first conveyor belt 110 is a release film, the main material belt 212 is a foam belt, and the adhesive layer belt 213 is a double-sided adhesive tape.

[0043] Reference Figure 2 As shown, in some specific embodiments of the present invention, S2 includes: S21: The primary die-cutting assembly 300 cuts the main material tape 212 and the adhesive tape 213 , and part of the main material tape 212 and part of the adhesive tape 213 form a semi-finished tape 220 on the substrate, and another part of the main material tape 212 and another part of the adhesive tape 213 form a waste tape 230 .

[0044] Furthermore, the semi-finished product on the semi-finished product belt 220 is in a frame shape. In this embodiment, the unprocessed main material and adhesive layer are in a plate shape, and the main material and adhesive layer required for the finished product are in a door frame shape. After processing, the main material and adhesive layer are in the door frame shape. The part inside the door frame is formed into waste, while the semi-finished product and the base belt 210 are kept continuous, and the waste is also kept continuous with the base belt 210. The semi-finished product belt 220 and the waste belt 230 are formed respectively during the conveyance of the base belt 210.

[0045] Reference Figure 2 As shown, in some specific embodiments of the present invention, S3 includes: S31: the separation roller is attached to the waste belt 230 and separates the waste belt 230 from the semi-finished belt 220; S32: The semi-finished belt 220 of the separation roller is combined with the second conveyor belt 440 into one; S33: The second conveyor belt 440 is rolled up.

[0046] In this embodiment, by adhering the separation roller to the waste belt 230, the waste belt 230 can rotate directly relative to the semi-finished product belt 220 and move to be combined with the second conveyor belt 440 to form a whole. The waste belt 230 is collected by the wound second conveyor belt 440.

[0047] Reference Figure 1 As shown, in some specific embodiments of the present invention, S4 includes: S41: The secondary die-cutting assembly 500 penetrates the die-cut semi-finished product belt 220 to form a finished product and a waste block; S42: The waste blocks are recycled and the finished products are separated from the first conveyor belt 110.

[0048] In this embodiment, the COVER tape, foam tape and double-sided tape on the semi-finished belt 220 need to be die-cut to form a through-hole structure. The shapes of the through-hole structures include rectangular and circular. The secondary die-cutting component 500 directly penetrates the semi-finished belt 220 and the first conveyor belt 110, so that the waste is directly discharged from the bottom of the first conveyor belt 110. During the die-cutting process, the finished product is directly separated from the waste, thereby realizing the production of the finished product.

[0049] Reference Figure 4 As shown, the second embodiment of the present invention provides a die-cutting device, using the waste material utilization method of the first aspect. It is worth understanding that the die-cutting device using the waste material utilization method of the first aspect can eliminate device errors and improve material utilization.

[0050] In this embodiment, the die-cutting device includes: a conveying component 100, a compound component 200, a primary die-cutting component 300, a recycling component 400, a secondary die-cutting component 500, and a step detection component are sequentially arranged along the conveying direction; The conveying assembly 100 includes a first conveying belt 110 capable of conveying along a conveying direction; the composite assembly 200 includes a base belt 210 and is used to composite the base belt 210 to the first conveying belt 110; The primary die-cutting component 300 is used to cut the base tape 210 into a semi-finished tape 220 and a waste tape 230; the recycling component 400 is used to recycle the waste tape 230 and form a waste roll, and the waste roll has a calibrated state; The secondary die-cutting assembly 500 is used to cut the semi-finished product belt 220 into finished products; The step detection component is used to detect the actual step of the conveying component 100; The waste roll is configured as follows: in a calibration state, it is disposed on the conveying assembly 100 and is capable of unwinding the waste belt 230 along the conveying direction, and the step detection assembly detects the actual step of the conveying assembly 100 through the waste belt 230 .

[0051] In this embodiment, the first conveyor belt 110 passes through the composite component 200, the primary die-cutting component 300, the recycling component 400, the secondary die-cutting component 500, and the step detection component in sequence along the conveying direction, and performs corresponding processing. The specific processing flow is as follows: When the first conveyor belt 110 passes through the composite assembly 200, the first conveyor belt 110 is composited with the base belt 210, and the base belt 210 is driven to move by the first conveyor belt 110; When the first conveyor belt 110 passes through the primary die-cutting assembly 300, the base belt 210 on the first conveyor belt 110 is cut into a semi-finished belt 220 and a waste belt 230; When the first conveyor belt 110 passes through the recycling assembly 400, the waste belt 230 is separated from the first conveyor belt 110 and is recycled as a waste roll; When the first conveyor belt 110 passes through the secondary die-cutting assembly 500 , the semi-finished belt 220 is processed into a finished product.

[0052] When the processing of the conveying base belt 210 of the first conveyor belt 110 is completed, the conveying roll of the conveying device for conveying the first conveyor belt 110 is replaced with a waste roll, so that the conveying device unwinds the waste roll as a waste belt 230, and the waste belt 230 passes through the composite component 200, the primary die-cutting component 300, the recycling component 400, the secondary die-cutting component 500, and the step detection component in the conveying direction.

[0053] When the scrap tape 230 passes through the secondary die-cutting assembly 500 , the scrap tape 230 is die-cut by the secondary die-cutting assembly 500 .

[0054] When the scrap tape 230 passes through the pitch detection component, if the set pitch of the conveying component 100 is consistent with the actual pitch, the secondary die-cutting component 500 should directly cut the notch position of the scrap tape 230, and will not cut on the scrap tape 230, so that the scrap tape 230 can remain intact after passing through the secondary die-cutting component 500. Similarly, if the set pitch of the conveying component 100 is inconsistent with the actual pitch, the secondary die-cutting component 500 will directly cut on the scrap tape 230, causing the scrap tape 230 to be defective. The pitch detection component can determine that there is an error between the set pitch and the actual pitch by detecting the defect position of the scrap tape 230, and the operator can make adjustments based on the error, or the die-cutting equipment can make automatic adjustments based on the error.

[0055] Reference Figure 4 As shown, in some specific embodiments of the present invention, the recycling component 400 includes a recycling unwinding roller 410, a separation pair of rollers 420, a recycling winding roller 430, and a second conveyor belt 440 arranged between the recycling unwinding roller 410 and the recycling winding roller 430 and passing through the separation pair of rollers 420, the first conveyor belt 110 passes through the separation pair of rollers 420, the second conveyor belt 440 is compounded with the waste belt 230, and the first conveyor belt 110 is compounded with the semi-finished product belt 220.

[0056] Specifically, the second conveyor belt 440 and the waste belt 230 are combined by the separation roller 420, so that the waste belt 230 moves with the second conveyor belt 440 until it is rolled up into a waste roll together with the second conveyor belt 440. In this embodiment, the first conveyor belt 110 and the second conveyor belt 440 are both low-adhesion, such as release films.

[0057] Reference Figure 4 As shown, in some specific embodiments of the present invention, the secondary die-cutting assembly 500 includes an adhesive unwinding roller 240, an adhesive roller 250, an adhesive recovery roller 260, and an adhesive tape 270 disposed between the adhesive unwinding roller and the adhesive recovery roller 260 and passing through the adhesive roller 250, and the adhesive tape 270 is used to adhere the waste material after the semi-finished product tape 220 is cut.

[0058] Specifically, the waste material when the semi-finished product belt 220 is cut to form the finished product is adhered by the adhesive tape 270, so that the waste material is separated from the semi-finished product, and the semi-finished product is formed into a complete finished product. Moreover, when the semi-finished product belt 220 is cut for the second time, the waste material and the semi-finished product are directly separated, making the forming of the finished product more efficient.

[0059] Reference Figure 4As shown, in some specific embodiments of the present invention, the die-cutting equipment also includes: a sticker composite component 600 and a sticker die-cutting component 700. The step detection component, the sticker composite component 600, and the sticker die-cutting component 700 are arranged in sequence along the conveying direction. The sticker composite component 600 includes a hard sticker tape 610 and is used to composite the sticker tape 610 to a semi-finished product tape 220. The sticker die-cutting component 700 is used to cut the sticker tape 610 into stickers corresponding to the finished product.

[0060] It should be noted that, because the overall structure of the base band 210 is a layered structure and the overall texture of the base band 210 is relatively soft, the storage and subsequent transportation of the finished product is relatively inconvenient, and the finished product is easily folded, resulting in defects.

[0061] In this embodiment, by compounding the hard sticker with the finished product, the sticker can effectively support the finished product, making the finished product less likely to deform, thereby making the storage and subsequent transportation of the finished product more convenient. In addition, the finished product is not easily damaged, which can effectively prevent good products from becoming defective products, thereby improving the overall yield rate of the finished product.

[0062] Reference Figure 4 As shown, in some specific embodiments of the present invention, the composite component 200 includes a primary composite component 280 and a secondary composite component 290. The primary composite component 280 is used to composite the substrate belt 211 to the first conveyor belt 110, and the secondary composite component 290 is used to composite the main material belt 212 and the adhesive layer belt 213 to the substrate belt 211.

[0063] Among them, the primary composite component 280 includes a substrate unwinding roller, a substrate roll and a primary composite roller pair. The substrate is rolled on the substrate unwinding roller and is unwound into a substrate belt 211 through the substrate unwinding roller. The substrate belt 211 passes through the primary composite roller pair together with the first conveyor belt 110 and is composited into one through the primary composite roller pair.

[0064] Among them, the secondary composite component 290 includes a main material unwinding roller, an adhesive layer unwinding roller, a main material roll, an adhesive layer roll and a secondary composite roller pair. The main material roll is arranged on the main material unwinding roller and is unwound into a main material belt 212 through the main material unwinding roller. The adhesive layer roll is arranged on the adhesive layer unwinding roller and is unwound into an adhesive layer belt 213 through the adhesive layer unwinding roller. The first conveyor belt 110, the substrate belt 211, the main material belt 212 and the adhesive layer belt 213 pass through the secondary composite roller pair together and are composited into one through the secondary composite roller pair.

[0065] Reference Figure 4 As shown, in some specific embodiments of the present invention, the die-cutting device also includes: a first face paper assembly 800, which is arranged in the primary die-cutting assembly 300, the face paper assembly has a first face paper tape 810, the primary die-cutting assembly 300 has a primary die-cutting head, and the first face paper tape 810 is arranged between the primary die-cutting head and the base tape 210.

[0066] It should be noted that the surface of the base belt 210 is a glue layer, and the base belt 210 is not tightly bonded to the first conveyor belt 110, resulting in the glue layer adhering to the primary die-cutting head when the primary die-cutting head cuts the base belt 210, thereby causing the base belt 210 to separate from the first conveyor belt 110, and the base belt 210 bulges, affecting subsequent processing.

[0067] In this embodiment, the first paper tape 810 is spaced between the primary die-cutting head and the base tape 210, thereby reducing the possibility of the primary die-cutting head adhering to the base tape 210, making the die-cutting of the primary die-cutting head smoother, and more conducive to the continuity of the primary die-cutting head processing, thereby improving production efficiency and production quality. Among them, the first paper tape 810 is a release paper, and the connection strength between the first paper tape 810 and the adhesive layer is low, and the first paper tape 810 is easier to separate from the adhesive layer. The first paper assembly 800 includes a first paper unwinding roller 820, a first paper winding roller 830, and a first paper abutting roller 840. The first paper tape 810 is arranged between the first paper unwinding roller 820 and the first paper winding roller 830, and the first paper tape 810 abuts against the base tape 210 through the first paper abutting roller 840.

[0068] Reference Figure 4 As shown, in some specific embodiments of the present invention, the die-cutting device also includes: a second face paper assembly 900, which is arranged in the secondary die-cutting assembly 500, the face paper assembly has a second face paper belt 910, the secondary die-cutting assembly 500 has a secondary die-cutting head, and the second face paper belt 910 is arranged between the secondary die-cutting head and the base belt 210.

[0069] In this embodiment, the second paper tape 910 plays the same role as the first paper tape 810, except that the second paper tape 910 and the first paper tape 810 are separated by different objects, and the second paper tape 910 separates the secondary die-cutting head and the base tape 210. The second paper assembly 900 and the first paper assembly 800 have basically the same structure, which will not be described in detail.

[0070] Reference Figure 4 As shown, in some specific embodiments of the present invention, the die-cutting equipment further includes: a separation component A00, a step detection component and a separation component A00 are sequentially arranged along the conveying direction, and the separation component A00 is used to separate the finished product from the first conveyor belt 110.

[0071] It is worth understanding that at the conveying end of the first conveyor belt 110, the finished product has been formed. At this time, the finished product needs to be separated from the first conveyor belt 110 to obtain a separate finished product for the convenience of storage and subsequent transportation of the finished product.

[0072] In this embodiment, the first conveyor belt 110 includes a turning position. At the turning position, the first conveyor belt 110 changes from horizontal conveying to conveying toward the ground, so that the first conveyor belt 110 forms an angle with the finished product in a horizontal state at the turning position, and the finished product is easier to separate from the first conveyor belt 110. At the same time, the separation component A00 is docked at the turning position of the first conveyor belt 110 in the horizontal direction, so that the separation component A00 will guide the finished product to move in the horizontal direction, and then completely separate from the first conveyor belt 110 moving toward the ground, thereby improving the separation efficiency and separation reliability.

[0073] Reference Figure 4 As shown, in some specific embodiments of the present invention, the die-cutting device further includes: a collection box B00, which is arranged at the end of the separation component A00 along the conveying direction and is used to collect finished products.

[0074] It is worth understanding that the finished products will fall into the collection box B00 at the end of the conveying direction and be collected by the collection box B00, so as to facilitate the sorting and storage of the finished products, and the subsequent overall transportation of the finished products will be more convenient.

[0075] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
