Description

Technical Field

[0001] The invention relates to the field of composite belt production, in particular to hard rubber coated composite roller knife punching equipment and a process thereof. Background Art

[0002] Conventional hard rubber coating equipment can only perform coating and laminating functions, and does not have punching functions. After coating and laminating, the material must be rolled up before proceeding to the next process. However, due to the thickness of hard rubber products, the material is prone to defects such as delamination and wrinkling of the release paper after the process is rolled up, resulting in a high defect rate for the entire process. In addition, for products with special shapes, the coating, laminating, striping and cutting functions cannot meet the special requirements. Striping and cutting can only meet the needs of rectangular and square products, while roller knife punching can meet various shape requirements. Summary of the Invention

[0003] The purpose of the present invention is to provide a hard rubber coated composite roller knife punching equipment and process, which can solve the problem of release paper delamination, wrinkles and other defects easily occurring in the conventional process and equipment when the composite is directly rolled up.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a punching device for a hard rubber coated composite roller knife, comprising a main frame and a transmission mechanism, wherein the transmission mechanism provides power for the parts on the frame, the main frame comprises an upper and lower layers, the upper end of the upper layer of the main frame is fixed with a first discharge shaft, a second discharge shaft, and a first receiving shaft in sequence from left to right, the lower end of the upper layer of the main frame is fixed with a first composite shaft and a transmission shaft in sequence from left to right, the lower layer of the main frame is fixed with a third discharge shaft and a fourth discharge shaft in sequence from left to right, the left side of the main frame is fixed with a second receiving shaft, and the right side of the main frame is fixed with a third receiving shaft, characterized in that: a roller knife loading mechanism is arranged between the first composite shaft and the transmission shaft, the left side of the third receiving shaft is fixed with a sub-frame, and the upper frame of the sub-frame is fixed with a fifth discharge shaft and a coating station in sequence.

[0005] Furthermore, the coating station includes a first limiting shaft, a second limiting shaft, and a coating shaft. The first limiting shaft and the second limiting shaft are fixed on the left and right sides of the coating shaft. A processing agent box is fixed below the coating shaft, and more than three-quarters of the volume of the coating shaft is located in the processing agent box.

[0006] Furthermore, a waste scraper is fixed between the roller-knife mechanism and the transmission shaft, and the transmission mechanism is a motor.

[0007] Furthermore, the roller cutter loading mechanism includes a knife closer, a knife locker, a roller cutter, a knife holder, and a lower knife shaft. The knife holders are respectively arranged on the upper surface of the lower end of the upper layer of the main frame on the left and right sides. The roller cutter and the lower knife shaft are fixed on the inner surface of the knife holder through the knife closer. The roller cutter is located above the lower knife shaft. The knife locker is respectively fixed on the upper surface of the knife holder and locks the roller cutter and the lower knife shaft to the knife holder.

[0008] A process for hard rubber coated composite roller knife punching comprises the following steps:

[0009] Step S1: The hard rubber is conveyed to the coating station through the fifth unloading shaft for brushing with a treatment agent;

[0010] Step S2: The hard rubber after being brushed with the treatment agent is conveyed to the first composite shaft, the double-sided tape is synchronously conveyed to the first composite shaft through the first unwinding shaft to be composited with the side of the hard rubber brushed with the treatment agent, the release paper is synchronously conveyed to the first composite shaft through the third unwinding shaft to be composited with the adhesive backing side of the hard rubber after being brushed with the treatment agent, the drag film is synchronously conveyed to the first composite shaft through the fourth unwinding shaft to be composited with the side with the release paper attached, the paper attached to the hard rubber is peeled off from the hard rubber through the first composite shaft and synchronously conveyed to the third receiving shaft to be rolled;

[0011] Step S3: The laminated hard rubber is transferred to the die-cutting transfer mechanism, and the single-sided tape is transferred to the die-cutting transfer mechanism via the second unwinding shaft. The double-sided tape is laminated along the edge of the roller blade and laminated with the double-sided tape on the upper surface of the hard rubber. The single-sided tape is laminated and die-cut simultaneously. The waste material from the die-cutting is transferred to the first receiving shaft via the waste scraper for winding.

[0012] Step S4: After the waste edges are removed, the hard rubber and the drag film are peeled off through the transmission shaft, and the drag film is sent to the second receiving shaft through the transmission shaft to be rolled, and the hard rubber is collected manually.

[0013] Furthermore, the widths of the double-sided tape, release paper and drag film in step S2 are all wider than that of the hard rubber, and the hard rubber is laminated with the double-sided tape, release paper and drag film in a full-surface manner.

[0026] See also Figures 1 to 3 The present invention provides another embodiment: a process for hard rubber coated composite roller knife punching, comprising the following steps:

[0027] Step S1: The hard rubber is conveyed to the coating station 13 via the fifth unloading shaft 12 for brushing with a treatment agent; the side of the hard rubber that is not attached to the hard rubber paper is brushed with the treatment agent via the coating station 13;

[0028] Step S2, the hard rubber after being brushed with the treatment agent is conveyed to the first composite shaft 5, the double-sided tape is synchronously conveyed to the first composite shaft 5 through the first unloading shaft 2 and composited with the side of the hard rubber brushed with the treatment agent, the release paper is synchronously conveyed to the first composite shaft 5 through the third unloading shaft 7 and composited with the adhesive back surface of the hard rubber after being brushed with the treatment agent, the drag film is synchronously conveyed to the first composite shaft 5 through the fourth unloading shaft 8 and composited with the side with the release paper, the hard rubber self-contained paper is peeled off from the hard rubber through the first composite shaft 5 and synchronously conveyed to the third receiving shaft 10 to be rolled; after the hard rubber is brushed with the treatment agent, the side brushed with the treatment agent is composited with the double-sided tape, the release paper is set on the left and adhered to the adhesive back surface of the hard rubber, the drag film is set on the right and composited with the hard rubber release paper synchronously through the first composite shaft 5 and composited on the release paper.

[0029] In step S3, the laminated hard rubber is transferred to the die-cutting and transferring mechanism. The single-sided tape is transferred to the die-cutting and transferring mechanism via the second unloading shaft 3. The tape is laminated with the double-sided tape on the upper surface of the hard rubber along the edge of the roller cutter 21. The single-sided tape is bonded to the double-sided tape while being die-cut. The die-cut waste is transferred to the first receiving shaft 4 via the waste discharge scraper 17 for winding. The die-cutting and transferring mechanism uses the roller cutter 21 to die-cut and remove the waste edge. The waste edge is peeled off by the waste discharge scraper 17. The single-sided tape placed on the second unloading shaft 3 can help discharge the die-cut waste. The first receiving shaft 4 rotates to rewind the waste.

[0030] Step S4: After the scrap edges are removed, the hard rubber is separated from the drag film by a transmission shaft 6. The drag film is then conveyed to a second take-up shaft 9 for roll formation. The hard rubber is then collected manually. The drag film is then separated from the scrap edged hard rubber by a transmission belt and rewound to the second take-up shaft 9. The hard rubber is die-cut as required and collected manually. The specific die-cut dimensions vary depending on the product, with a tolerance of ±1mm for each product.

[0031] Please continue reading Figure 1 As shown, in another embodiment of the present invention, the widths of the double-sided tape, release paper, and drag film in step S2 are all wider than the width of the hard rubber, and the hard rubber, double-sided tape, release paper, and drag film are all laminated to the entire surface. The final product needs to be laminated to the entire surface and have a consistent width. In order to ensure that the produced product is qualified, the double-sided tape, release paper, and drag film are all wider than the width of the hard rubber, so that the waste of hard rubber is reduced during the die-cutting process.

[0032] Please continue reading Figure 1 As shown, in one embodiment of the present invention, the blade locker 20 of the roller blade loading mechanism 11 in step S3 locks the roller blade 21 until it punches the drag film, and the die-cutting method is such that the drag film is continuous and the remaining materials are cut. The blade locker 20 adjusts the depth of the die-cutting of the roller blade 21, ensuring that the die-cutting process is completed while also ensuring that the drag film can continue to transport the hard rubber thereon.

[0033] The present invention has the following working principle: the equipment of the present invention has the functions of coating, compounding, and loading the punching roller simultaneously. By arranging a die-cutting loading mechanism between the compounding shaft and the transmission shaft, the hard rubber can be directly die-cut after compounding, thereby avoiding the occurrence of product wrinkles, delamination and other undesirable problems caused by process flow. Compared with the existing process, the process of the present invention simplifies the process, improves the yield and efficiency, and meets the demand for products of different shapes.

[0034] The above description is only a preferred embodiment of the present invention and should not be understood as limiting the present application. All equivalent changes and modifications made within the scope of the patent application of the present invention should fall within the scope of the present invention.
