Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of jelly sticker production (including TPE stickers, TPU stickers, silicone stickers, and jelly-like labeling products, collectively referred to as "jelly stickers"), and specifically to a jelly sticker production process. Background Art
[0002] The traditional jelly sticker production process steps are: 1. Flat sheet printing: Print the pattern on a flat sheet of film or other printing carrier. 2. Cutting: Cut the printed flat sheet of film or other printing carrier into the required shape and size. 3. Apply jelly glue: Use mold injection to inject jelly glue on the cut film or other printing carrier. 4. Die cutting: Perform a single flat sheet die cutting to cut the jelly glue and film or other printing carrier into the final shape. The above traditional processes mainly have the following defects:
[0003] 1. Due to the use of flat-sheet printing press, the plate size is large and the cost is high. The large plate size leads to an increase in relative shrinkage (deformation) error, which easily causes the die-cut pattern to be off-center.
[0004] 2. The injection molding machine is used, and the injection mold needs to be opened. Each set costs about 18,000 to 25,000 yuan, which is costly. 1,800 PCS are produced per hour, and 43,200 PCS are produced per day. The efficiency is low.
[0005] 3. Flat sheet die cutting is adopted. After die cutting, the jelly products need to be manually discharged or put into the waste discharge device for sorting. Due to the influence of the plate opening, the die cutting centering error is large and the precision is relatively low (plus or minus 0.5mm).
[0006] In summary, the present invention designs a jelly patch production process with low cost, high efficiency and good use effect. Summary of the invention
[0007] In view of the shortcomings of the prior art, the present invention aims to provide a jelly sticker production process. The use of rotary printing and rotary die-cutting machines realizes continuous operation, improves production efficiency, and reduces production cycles. The casting process can ensure that the jelly glue is evenly applied to the film or other printing carrier, ensuring the quality and consistency of the product. The entire process has low cost and high efficiency.
[0008] In order to achieve the above object, the present invention is implemented through the following technical scheme: a jelly patch production process comprises the following steps:
[0009] 1. Rotary printing: Use a rotary printing press for continuous operation to print the pattern on a continuous paper tape;
[0010] 2. Jelly glue on the casting process: the jelly glue is evenly cast on a continuous film or other printing carrier using the casting process;
[0011] 3. Rotary continuous die cutting: Use a rotary die cutting machine for continuous die cutting to cut the jelly glue and film or other printing carriers into the final shape.
[0012] Preferably, the step 1 is specifically as follows: the paper tape passes through various printing units of the printing press, each printing unit is responsible for printing a color or a part of a pattern, the roller on the printing press contacts the film or other printing carrier, and prints the pattern onto the film or other printing carrier through ink transfer; after printing is completed, the film or other printing carrier continues to move forward and enters the next process.
[0013] Preferably, the step 2 is specifically as follows: the printed film or other printing carrier enters the casting machine, the jelly glue is cast onto the film or other printing carrier through the die head of the casting machine, and the cast film or other printing carrier continues to move forward and is ready to enter the next process.
[0014] Preferably, the step 3 is specifically as follows: the film or other printing carrier coated with jelly glue enters the die-cutting machine, the die-cutting roller on the die-cutting machine contacts the film or other printing carrier, and cuts the jelly glue and the film or other printing carrier into a desired shape together through pressure, and the cut jelly stickers are separated from the film or other printing carrier roll to become the final product.
[0015] The beneficial effects of the present invention are:
[0016] 1. Improved efficiency: Rotary printing and rotary die-cutting realize continuous operation and improve production efficiency.
[0017] 2. Stable quality: The casting process can evenly apply the jelly glue to ensure the consistency of product quality.
[0018] 3. Cost reduction: Continuous operation reduces intermediate links and reduces production costs. DETAILED DESCRIPTION
[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0020] This specific implementation adopts the following technical solution: the jelly patch production process includes the following steps:
[0021] 1. Rotary printing: Use a rotary printing press to perform continuous operation and print the pattern on a continuous film or other printing carrier;
[0022] 2. Jelly glue on the casting process: the jelly glue is evenly cast on a continuous film or other printing carrier using the casting process;
[0023] 3. Rotary continuous die cutting: Use a rotary die cutting machine for continuous die cutting to cut the jelly glue and film or other printing carriers into the final shape.
[0024] It is worth noting that the step 1 is specifically as follows: the paper tape passes through the various printing units of the printing press, each printing unit is responsible for printing a color or a part of a pattern, the roller (printing plate) on the printing press contacts the film or other printing carrier, and prints the pattern onto the paper tape through ink transfer; after printing is completed, the paper tape continues to move forward and enters the next process.
[0025] It is worth noting that the step 2 is specifically as follows: the printed film or other printing carrier enters the casting machine, the jelly glue is evenly cast onto the film or other printing carrier through the die head of the casting machine, and the cast film or other printing carrier continues to move forward and is ready to enter the next process.
[0026] During this process, the thickness and uniformity of the jelly glue need to be controlled to ensure the quality and performance of the final product.
[0027] In addition, the step 3 is specifically as follows: the film or other printing carrier coated with jelly glue enters the die-cutting machine, the die-cutting roller on the die-cutting machine contacts the film or other printing carrier, and cuts the jelly glue and the film or other printing carrier into a desired shape together through pressure, and the cut jelly stickers are separated from the film or other printing carrier roll to become the final product; the waste (excess film or other printing carrier and jelly glue) is collected for subsequent processing.
[0028] The process of this specific embodiment adopts a rotary printing press: the printing plate is small and the cost is low. The printing cost of producing jelly stickers can be saved by 50% compared with the printing of flat sheet printing press. The small printing plate reduces the shrinkage (deformation) error, the product pattern is easier to control, and the good product centering rate is obviously superior to the flat sheet printing machine.
[0029] The process of this specific implementation method adopts customized equipment: no mold is required, and a heated casting process is used to save costs and produce 75,000 PCS per hour, with a daily output of 1.8 million PCS, with high efficiency and low cost.
[0030] The process of this specific implementation adopts a rotary die-cutting machine: jelly products can achieve continuous die-cutting, waste discharge, output and other online operations, with high efficiency and low cost. Small opening, stable continuous operation, small error, high precision (plus or minus 0.1mm)
[0031] Through the above steps, the production process of jelly patches in this specific implementation method achieves the production goals of high efficiency, low cost and high quality.
[0032] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
