[0039] See also Figure 3 and Figure 4The glue storage tank 102 is arranged on the top of the printing roller 101. The glue storage tank 102 brushes glue on the surface of the printing roller 101 through the glue brush 116 at the bottom. The glue outlet of the glue storage tank 102 is fixedly connected with a strip frame 114. The interior of the strip frame 114 is equipped with an extended support plate 115 and a glue brush 116. The support plate 115 supports the glue brush 116 to prevent the glue brush 116 from sagging due to gravity and contacting the lace groove 108. The glue brush 116 is located on the top of the support plate 115, and one end of the glue brush 116 extending from the strip frame 114 contacts the surface of the printing roller 101.

[0040] Specifically, see Figures 2 to 4 A bottom plate 117 is provided at the bottom of the printing roller 101, the printing roller 101 and the glue storage tank 102 are fixed on the bottom plate 117 through a first support frame 118, the scraper aaa and the guide roller 121 are fixed on the bottom plate 117 through a second support frame 119, the top of the bottom plate 117 is fixedly connected with the first support frame 118 and the second support frame 119, the printing roller 101 is installed on the first support frame 118, and the second support frame 119 is connected with the guide roller 121, the substrate passes through the bottom of the guide roller 121 and the printing roller 101, and when the substrate passes, it will come into contact with the guide roller 121 and the printing roller 101, the guide roller 121 guides the substrate, and the printing roller 101 applies glue to the surface of the substrate.

[0041] Specifically, see Figure 2 and Figure 3 One side of the first support frame 118 is connected to a mounting cover 122 through a hinge. The mounting cover 122 fixes the bearings at both ends of the printing roller 101 to the first support frame 118 through bolts. The printing roller 101 can rotate on the first support frame 118 through the bearings at both ends. The other end of the mounting cover 122 is installed on the first support frame 118 through bolts, and the bearings at both ends of the center rod 103 are fixed inside. The printing roller 101 rotates on the first support frame 118 through the bearings at both ends. The glue storage tank 102 is connected to the top of the first support frame 118.

[0042] Specifically, see Figure 8 A sealing rubber ring 120 is fixedly connected to one end of the lace block 106 and the extension block 105 close to the center block 104. The sealing rubber ring 120 can play a sealing role at the connection between the extension block 105 and the lace block 106 or the center block 104 to prevent glue from entering the position of the spline part 107. Grooves matching with the sealing rubber ring 120 are provided at both ends of the center block 104 and the extension block 105. The grooves are smaller than the size of the extended sealing rubber ring 120, so that the sealing rubber ring 120 can be deformed to play a sealing role.

[0043] Specifically, the lace groove 108 on the surface of the lace block 106 includes a fold line shape, a wave shape and a straight line shape. The lace groove 108 has a variety of shapes, not limited to the above-mentioned fold line shape, wave shape and straight line shape, and can also be set to a triangle, an ellipse or an irregular shape, which can be selected according to the situation.

[0044] Specifically, see Figure 1 and Figure 2 The top of the glue storage tank 102 is connected to a top cover 123 through a hinge, and the top cover 123 covers the top of the glue storage tank 102 to prevent foreign matter from entering the glue storage tank 102.

[0045] In this embodiment, the glue storage tank 102 is located on the top of the printing roller 101, and the glue storage tank 102 stores glue used for producing the adhesive tape. The glue outlet at the bottom of the glue storage tank 102 is blocked by the strip frame 114, and the glue can flow out from the glue brush 116 inside the strip frame 114. The support plate 115 supports the glue brush 116 to prevent the glue brush 116 from sagging due to gravity and contacting the surface of the printing roller 101. Through the rotational contact between the glue brush 116 and the printing roller 101, the glue will be coated on the surface of the printing roller 101, and then coated on the substrate through the rotation of the printing roller 101, and the substrate passes through the guide roller 121 and the bottom of the printing roller 101 in sequence;

[0046] When the printing roller 101 rotates, the lace groove 108 on one side of the lace block 106 is recessed inward so that it will not contact the glue brush 116 on the top, thereby avoiding the adhesion of glue, so as to produce the smooth edge on the tape roll 201. At the same time, the lace groove 108 has a variety of shapes, not limited to the above-mentioned broken line shape, wavy shape and straight line shape, but can also be set to a triangle, ellipse or irregular shape to achieve the effect of being suitable for different usage conditions. For the situation where the glue layer is located on both sides of the smooth edge, the lace groove 108 can be set to a protruding style, so that the lace grooves 108 on both sides can contact the glue brush 116 on the top, while the remaining parts do not contact the glue brush 116, thereby printing a style with glue layers coated on both sides. At the same time, the lace groove 108 can be set to the same diameter as the center block 104, so as to achieve the situation where there is a smooth edge on one side of the tape roll 201. Fig.10 It is a schematic diagram of the base fabric after gluing, in which the smooth edge part and the glue part are arranged alternately;

[0047] When replacing the lace blocks 106 on both sides, loosen the bolts on the mounting cover 122 to remove the printing roller 101 and the bearings at both ends thereof, and remove them from the center rod 103 by rotating the tension plate 112. The diameter of the threaded portion 111 is larger than the diameter of the bearing, so it will not affect the removal of the tension plate 112. After the tension plate 112 is removed, the spring 113 is reset. At this time, the spring 113 and the circular plate 110 can be removed, and then the lace groove 108 and the extension block 105 are removed from the spline portion 107 and then replaced. The extension block 105 has the function of extending the distance between the lace blocks 106 at both ends. The distance between the two lace blocks 106 can be adjusted by replacing the extension blocks 105 of different lengths. The opposite steps are used during installation.

[0048] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
