Description

Technical Field

[0001] This utility model relates to the field of impregnation machine mechanical technology, and in particular to an improved paper feeding mechanism for impregnating paper during the production of adhesive film paper, which pulls the adhesive film paper from the impregnation process to the drying box. Background Technology

[0002] Traditional adhesive paper requires processing steps such as unwinding, glue impregnation, and drying during production. After the glue impregnation process, the paper is drawn by the paper feeding mechanism to the drying box to dry the glue on the paper surface. In the existing production process, the paper feeding mechanism of the glue-dipping machine consists of two parallel paper feeding chains and paper feeding rods set up inside the drying box. The paper feeding rod is just an ordinary square tube with two hooks fixed at each end. When feeding paper, the film paper is rolled onto the square tube, and the hooks at both ends of the paper feeding rod are directly inserted into the gap between the paper feeding chain connecting parts for pulling to the later section for shearing. However, after the film paper is impregnated with glue, its toughness will be weakened. If the paper breaks during the pulling process, the paper feeding rod cannot be removed at any time. It must go all the way to the later section and wait for the paper feeding chain to stop before the paper feeding rod can be removed from the gap between the paper feeding chain connecting parts for re-feeding the paper. This process not only wastes time and manpower, but also reduces the production efficiency of the product. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an improved paper feeding mechanism for a glue dipping machine.

[0004] The present invention adopts the following technical solution: An improved paper feeding mechanism for a glue dipping machine consists of two paper feeding chains and a paper feeding rod arranged in parallel inside a drying chamber. A pin block is fixed at the same position on the opposite side of each of the two paper feeding chains. The pin block is inserted into the paper feeding rod. Through the connection between the pin block and the elastic element on the paper feeding rod, the paper feeding rod can be easily removed from the two moving paper feeding chains. The square tube-shaped paper guide rod has a positioning block and an adjusting block fixed at both ends. The positioning block has a positioning hole, and the adjusting block has an adjusting hole. An elastic element is installed in the adjusting hole. A cover is fixed on the adjusting block outside the adjusting hole. The cover has the same hole as the adjusting hole. The pin block is fixed to the inside of the paper feed chain on one side, and a protruding pin is fixed to the outside on the other side. The outer diameter of the protruding pin is approximately smaller than the inner diameter of the adjusting hole on the adjusting block. The elastic element is a compression spring; The depth of the adjusting hole on the adjusting block is less than the sum of the lengths of the elastic element and the protrusion of the pin block when it is not compressed, and greater than the sum of the lengths of the elastic element and the protrusion of the pin block when it is fully compressed. Preferably, there are two protruding pins on one side of the pin block.

[0005] This utility model uses a telescopic paper guide rod, which combines a rectangular tube with an elastic element. The paper guide rod can be flexibly removed from the paper guide chain according to different paper break positions, which is convenient, quick, time-saving, and labor-saving, effectively improving production efficiency.

Detailed Implementation

[0007] See attached Figures 1-4 An improved paper feeding mechanism for a glue dipping machine consists of two paper feeding chains 2 and a paper feeding rod 3 arranged in parallel inside a drying chamber 1. A pin block 21 is fixed at the same position on the opposite side of each of the two paper feeding chains 2. The pin block 21 is inserted into the paper feeding rod 3. Through the connection between the pin block 21 and the elastic element on the paper feeding rod 3, the paper feeding rod 3 can be easily removed from the two moving paper feeding chains 2. The two ends of the square tube-shaped paper guide rod 3 are respectively fixed with a positioning block 31 and an adjusting block 32. The positioning block 31 is provided with a positioning hole 311, and the adjusting block 32 is provided with an adjusting hole 322. An elastic element 323 is provided in the adjusting hole 322. A cover 321 is fixed on the adjusting block 32 outside the adjusting hole 322. The cover 321 is provided with the same hole as the adjusting hole 322. The pin block 21 is fixed to the inner side of the paper guide chain 2 on one side, and a protruding nail 211 is fixed to the outside on the other side. The outer diameter of the protruding nail 211 is approximately smaller than the inner diameter of the adjusting hole 322 on the adjusting block 32. The elastic element 323 is a compression spring; The depth of the adjustment hole 322 on the adjustment block 32 is less than the sum of the lengths of the elastic element 323 and the protrusion 211 of the pin block 21 when it is not compressed, and greater than the sum of the lengths of the elastic element 323 and the protrusion 211 of the pin block 21 when it is fully compressed. Preferably, there are two protruding nails 211 on one side of the pin block 21.

[0008] When the paper feeding is initiated, the adhesive film paper is evenly wound onto the square-tube paper feeding rod 3. The operator first inserts the protruding pin 211 of the paper feeding chain 2 into the adjusting hole 322 on the adjusting block 32 on one side of the paper feeding rod 3, and then squeezes the other side of the paper feeding rod 3, so that the protruding pin 211 inserted into the adjusting hole 322 on the adjusting block 32 on one side of the paper feeding rod 3 compresses the elastic element 323. Since the depth of the adjusting hole 322 on the adjusting block 32 is greater than the protrusion of the elastic element 323 and the pin block 21 when fully compressed, The sum of the lengths of the nails 211, at this time, the elastic element 323 is compressed, and the paper guide rod 3 moves as a whole toward one end of the adjusting block 32; then insert the protruding nail 211 of the other end of the paper guide chain 2 into the positioning hole 311 on the positioning block 31. After the operator stops the operation, the elastic element 323 compressed in the adjusting hole 322 of the adjusting block 32 releases the elastic force, and the paper guide rod 3 moves as a whole toward one end of the positioning block 31. The paper guide rod 3 is then firmly fixed on the two parallel paper guide chains 2 inside the drying box 1. When an abnormal paper break occurs, locate the position where the paper guide rod 3 stops. The operator applies pressure directly from the positioning block 31 of the paper guide rod 3 to the adjusting block 32. The elastic element 323 is pressed by the protruding nail 211, and the paper guide rod 3 moves as a whole towards one end of the adjusting block 32. This allows the protruding nail 211 of the paper guide chain 2 to be easily pulled out from the positioning hole 311 on the positioning block 31. Then, the adjusting block 32 of the paper guide rod 3 can be removed from the protruding nail 211 on the other side of the paper guide chain 2.
