Detailed Implementation

[0029] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0030] This application provides an automatic tape applicator for packaging roll materials, such as... Figure 1 , 2 As shown, the automatic tape applicator 100 is arranged on a roll winding machine for automatically applying tape to the fully rolled roll 10 on the roll winding machine for packaging.

[0031] like Figure 3 , 8 As shown in Figure 9, the automatic tape applicator 100 includes a tape applicator 30 and a lifting mechanism 40 for driving the tape applicator 30 to move in the up and down direction. Under the drive of the lifting mechanism 40, the tape applicator 30 has a first working state of pasting the tape 20 onto the roll material 10 and a second working state of cutting the tape 20.

[0032] like Figure 4-7 As shown, the tape applicator 30 includes: a mounting frame 1 connected to the lifting mechanism 40, a tape unwinding assembly 2 and a cutting assembly 3 mounted on the mounting frame 1, and a guide wheel 4 rotatably mounted on the mounting frame 1 about a center line X1.

[0033] Mounting bracket 1 includes a first mounting plate 101 and a second mounting plate 102 arranged opposite each other on the left and right. The second mounting plate 102 is larger in the vertical direction than the first mounting plate 101 in the vertical direction, and at least a portion of the second mounting plate 102 is located on the upper side of the first mounting plate 101 for mounting the tape unwinding assembly 2.

[0034] The tape unwinding assembly 2 is used to mount and unwind tape rolls 20. The tape unwinding assembly 2 includes a pressure plate shaft 21 and a pair of pressure plates 22. The pressure plate shaft 21 extends in a left-right direction and has a head end 211 connected to a second mounting plate 102 and a suspended tail end 212. The pair of pressure plates 22 are mounted opposite each other on the pressure plate shaft 21, with a gap between them to accommodate the tape roll. One pressure plate 22 near the tail end 212 is detachably connected to the pressure plate shaft 21. When the pressure plate 22 at the tail end 212 is removed from the pressure plate shaft 21, the tape roll can be mounted on the pressure plate shaft 21, and then the pressure plate 22 can be mounted back onto the tail end 212 of the pressure plate shaft 21. The pair of pressure plates 22 clamp the tape roll, allowing the tape roll to be unwound on the pressure plate shaft 21.

[0035] In this embodiment, the guide wheel 4 is installed below the tape unwinding assembly 2. The guide wheel 4 is rotatably mounted between the first mounting plate 101 and the second mounting plate 102 around the center line X1. The tape 20 unwound at the tape unwinding assembly 2 passes around the front side of the guide wheel 4. When the tape applicator 30 is in the first working state, the guide wheel 4 presses the passed tape 20 onto the roll material 10, thereby realizing automatic tape application on the roll material.

[0036] The cutting assembly 3 includes a swing frame 31, a pair of pressure rollers 32 and a cutting blade 33. The swing frame 31 is rotatably mounted on the mounting frame 1 about the center line X1. The pair of pressure rollers 32 are rotatably mounted on the left and right sides of the swing frame 31, respectively. The cutting blade 33 is mounted on the swing frame 31 and is arranged between the pair of pressure rollers 32 and located outside the guide roller 4.

[0037] The swing frame 31 includes a pair of swing arms 311 arranged opposite to each other. The pair of swing arms 311 are respectively rotatably mounted on the outer side of the first mounting plate 101 and the second mounting plate 102, and rotate synchronously around the center line X1. Each swing arm 311 has a first end and a second end arranged opposite to each other with the center line X1 as the center. A return spring 5 is elastically connected between the first end of each swing arm 311 and the corresponding mounting plate. The return spring 5 is used to swing the swing arm 311 back to its original position when the corresponding swing arm 311 loses external pressure. The length of the return spring 5 when the tape applicator 30 is in the first working state is greater than the length when the tape applicator is in the second working state.

[0038] A pair of pressure rollers 32 are rotatably mounted on the second end of the corresponding swing arm 311. The outer end face of each pressure roller 32 protrudes from the outside of the swing arm 311. The blade of the cutting blade 33 is located on the inner side of the outer end face of each pressure roller 32. When the tape applicator 30 contacts the roll material 10, the pair of pressure rollers 32 press against the surface of the roll material 10 and can prevent the cutting blade 33 from cutting the roll material 10.

[0039] In this embodiment, when the lifting mechanism 40 drives the tape-applying mechanism 30 to descend closer to the roll material, the tape-applying mechanism 30 transitions from contact with the roll material to a first working state. In the first working state, the guide wheel 4 presses the tape 20 firmly onto the surface of the roll material 10. Under the pushing action of the roll material 10, a pair of pressure rollers 32 drive the cutting blade 33 to swing towards the rear of the guide wheel 4. At this time, the return spring 5 is stretched by the swing arm 311. After the roll material 10 rotates once, the guide wheel 4 wraps the tape 20 around the roll material 10 once, and the lifting mechanism 40 drives the tape-applying mechanism. Mechanism 30 moves upward to move away from the roll material below, and the tape-applying mechanism 30 changes to the second working state. Guide wheel 4 moves upward away from the roll material 10, and the force exerted by the roll material 10 on the pair of pressure rollers 32 gradually decreases. Return spring 5 pulls swing arm 311 to make the pair of pressure rollers 32 and cutting blade 33 swing forward. In the second working state, the cutting blade 33 and the pair of pressure rollers 32 swing below guide wheel 4. The blade edge of cutting blade 33 is located on the moving path of tape 20 between guide wheel 4 and roll material 10. Cutting blade 33 cuts tape 20 during forward swing. Lifting mechanism 40 drives tape-applying mechanism 30 to move up and down, so that tape-applying mechanism 30 switches between the first and second working states to achieve automatic tape application and automatic tape cutting. The structure is simple, the operation is convenient, and the packaging efficiency is effectively improved.

[0040] An air blowing assembly 6 is installed on the front side of the guide wheel 4 to blow the tape 20 toward the guide wheel 4. The air blowing assembly 6 includes an air blowing rod 61 extending in the left-right direction and a pair of first support rods 62 arranged opposite each other in the left and right directions. The air blowing rod 61 is supported on the front side of the guide wheel 4 by the pair of first support rods 62. The air blowing rod 61 has a plurality of air blowing holes 610 facing the guide wheel 4. The plurality of air blowing holes 610 are arranged at intervals in the left-right direction. The air blowing rod 61 is used to blow air onto the tape 20 that passes around the guide wheel 4, so that the tape 20 can stick tightly to the guide wheel 4 and prevent the tape from flying around and affecting the pasting efficiency.

[0041] A pressure rod assembly 7 is installed on the rear side of the guide wheel 4. The pressure rod assembly 7 includes a pressure rod 71 extending in the left-right direction and a pair of second support rods 72 arranged opposite each other. The pressure rod 71 is supported on the rear side of the guide wheel 4 by the pair of second support rods 72. Each second support rod 72 is connected to the mounting frame 1 by a compression spring 73. Each compression spring 73 pulls the corresponding second support rod 72, so that the pressure rod 71 presses against the guide wheel 4, preventing the guide wheel 4 from rotating randomly when it moves away from the roll material, which would cause the tape to become tangled.

[0042] A pair of transition shafts 103 are installed at intervals in the vertical direction between the tape unwinding assembly 2 and the guide wheel 4. Each transition shaft 103 is rotatably installed between the first mounting plate 101 and the second mounting plate 102. The pair of transition shafts 103 are parallel to the center line X1. The pair of transition shafts 103 allow the tape 20 to be threaded sequentially from top to bottom to prevent the tape 20 from flying around.

[0043] The lifting mechanism 40 includes a fixed frame 8 installed on the roll winding equipment, a lifting guide rail 9 and a lifting cylinder 11 installed on the fixed frame 8, and a lifting slider 12 that slides with the lifting guide rail 9. The mounting frame 1 is connected to the lifting slider 12 through a connecting frame 13. The air rod of the lifting cylinder 11 is connected to the lifting slider 12. The lifting cylinder 11 is used to drive the lifting slider 12 to move back and forth along the lifting guide rail 9.

[0044] This application uses a lifting mechanism to drive the tape-applying mechanism to lift and lower, thereby achieving automatic tape application, packaging, and tape cutting of rolls on a roll winding machine. This application has a simple structure, is easy to adjust, saves packaging time, and effectively improves packaging efficiency and reduces production costs.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made without departing from the spirit and scope of this application. The scope of protection claimed by this application is defined by the appended claims, specification, and their equivalents.
