[0017] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] like Figure 1-4 As shown, the soft PVC sheet concave die printing machine includes a frame consisting of a base 1, a wall panel 2 correspondingly arranged on the base 1, and a cross brace 3 arranged between the wall panels 2. A traction roller 4 and a driving device for driving the traction roller 4 to rotate are arranged on the frame. A glue pool 5 for immersing the lower part of the traction roller 4 is arranged below the traction roller 4. A passive roller 6 is arranged above the traction roller 4. A scraper 16 connected to two wall panels 2 for scraping off the glue and paint on the traction roller 4 is arranged on one side of the traction roller 4. A concave die for forming a manufacturer's logo on the product is arranged on the outer surface of the traction roller 4. A controller is also included. The controller is a PLC. PLC program control is adopted, digital management, and the degree of automation is high.

[0020] The frame is also provided with a fine-tuning mechanism for adjusting the distance between the traction roller 4 and the passive roller 6, and the fine-tuning mechanism includes two adjustment chambers 7 correspondingly arranged on the two wall panels 2, and a fine-tuning cylinder 8 arranged on the top of the two adjustment chambers 7, a guide rail 8 is arranged on the chamber wall of the two adjustment chambers 7, and also includes a bearing seat 9 running along the guide rail 8, and a bearing 10 arranged on the bearing seat 9 for connecting to the passive roller 6, a floating joint 11 for connecting to the bearing seat 9 is provided on the fine-tuning cylinder 8, and the fine-tuning cylinder 8 is connected to the controller signal.

[0021] The utility model also comprises an adjusting assembly for adjusting the upper and lower positions of the glue pool, wherein the adjusting assembly comprises a thin cylinder with a rod 12 arranged on the two wall panels 2, and a connecting plate 13 for connecting with the bottom of the glue pool 5 is arranged on the thin cylinder with a rod 12.

[0022] The driving device includes a fixed bearing seat and a fixed bearing correspondingly arranged on the two wall panels 2, and a motor reducer 14 is arranged on one side of a fixed bearing, and the motor reducer is connected to the controller signal. The motor reducer 14 can be a parallel shaft gear reducer.

[0023] During the specific implementation of the soft PVC sheet concave die printing machine, the traction roller is started, the traction roller is a plated steel roller, the molded soft PVC product enters between the traction roller and the passive roller, the passive roller is a silicone rubber roller, the stroke of the fine-tuning cylinder is adjusted according to the thickness of the product, the upper and lower rollers clamp the product, and the clamping force is moderate to ensure that the traction does not slip and the product does not deform; the traction steel roller drives the passive roller to rotate, and the product enters the subsequent process device at a uniform speed, and the PLC program sets the traction speed to be consistent with the product production speed; because the lower part of the traction roller is immersed in the glue pool, the traction roller is covered with a thin layer of glue paint while rotating. The glue paint used in this application is a quick-drying glue paint for printing, which avoids the use of dangerous chemicals such as ink and thinners in the current production process, which will also cause environmental pollution and affect the occupational health of operators, and the printed handwriting is clear, quick-drying and non-sticky. Because the manufacturer's logo, batch number, etc. are engraved on the concave die on the outer surface of the traction roller, when the scraper scrapes off the glue and paint on the traction roller, only the glue and paint inside the concave die will be retained. When the glue-carrying part of the traction roller contacts the soft PVC product and generates a certain pressure with the upper passive roller, the manufacturer's logo, batch number, etc. engraved on the concave die will be printed on the surface of the soft PVC product and enter the subsequent process.

[0024] The above technical solution enables product pulling and printing to be completed at one time, with a high degree of automation, reducing the number of operators, lowering labor intensity, and saving equipment investment costs and labor costs.
