DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Reference Figure 1-6 The multiple gluing structure for printing a linerless label shown in the figure comprises a base 1, on which a guide roller 2 for supporting and conveying the label is provided, and above the guide roller 2 a rubber roller 3 for gluing the label is provided, and a glue feeding mechanism feeds the glue in the glue box 4 to the rubber roller 3, and the rubber roller 3 rotates under the drive of a motor to evenly apply the glue on the label; at the same time, in order to ensure the fluidity of the glue, with the assistance of a quantitative mechanism, the water in the water tank 10 is fed to the glue feeding mechanism to realize the gluing operation.

[0024] Glue feeding mechanism: The glue box 4 is fixedly mounted on the base 1, and a sleeve 5 is arranged on the bottom surface of the glue box 4. The sleeve 5 is provided with three groups. The sleeve 5 is interconnected up and down and connected to the inside of the glue box 4. An auger 6 is rotatably connected inside the sleeve 5. The auger 6 passes through the glue box 4, and a coaxial worm gear 7 is arranged on the shaft of the auger 6. In order to drive the auger 6 to rotate and transport the glue inside the glue box 4, a mounting plate is arranged on the top surface of the glue box 4, and a worm 8 is rotatably connected to the mounting plate. The worm 8 and the worm wheel 7 are meshed with each other. The worm 8 is driven by a conveying motor 9 arranged on the glue box 4 to achieve the purpose of delivering the glue to the glue roller 3. The design of the worm wheel 7 and the worm 8 and the self-locking property of the worm 7 and the worm 8 can prevent them from loosening during use.

[0025] Quantitative mechanism: A groove chamber 61 is provided on the shaft of the auger 6, and a through hole 62 communicating with the outside is provided inside the groove chamber 61, and a protrusion 63 is provided on the inner wall of the groove chamber 61. The protrusion 63 cooperates with the limit block 12 sliding in the groove chamber 61. When the reciprocating rod 11 is not rotating, the notch on the limit block 12 cooperates with the protrusion 63 to achieve the purpose of dividing the space of the groove chamber 61. In order to remix the water and glue and improve the fluidity, the shaft of the auger 6 is connected to the inside of the water tank 10, so the water in the water tank 10 fills the inside of the groove chamber 61. When the conveying motor 9 rotates, the reciprocating rod 11 cooperates with the guide block 16 provided on the top surface of the water tank 10 through the rotating rod 13 provided on the top. The rotating rod 13 slides on the top surface of the guide block 16 and climbs up, thereby raising the limit block 12, and its notch is misaligned with the protrusion 63, so that water enters the sleeve 5 from the inside of the groove chamber 61 and is mixed during the rotation of the auger 6.

[0026] In order to enable the reciprocating rod 11 to be quickly reset during use, a bracket 17 is provided on the top surface of the water tank 10, and a hole is provided on the bracket 17. A resetter is provided on the top of the reciprocating rod 11 and is slidably connected in the hole. During the climbing process of the reciprocating rod 11, the resetter is squeezed and after passing the highest point of the guide block 16, it quickly drops to the lowest point, and the through hole 62 is blocked by the limit block 12 to achieve the purpose of quantitative water delivery.

[0027] In order to prevent the groove of the limit block 12 from being unable to align and adapt with the protrusion 63 after the reciprocating rod 11 is raised, a limit rod 64 is provided inside the groove chamber 61, and a limit groove 111 is provided on the outer wall of the reciprocating rod 11. The limit groove 111 cooperates with the limit rod 64 to achieve the reciprocating rod 11 to rise and fall while rotating simultaneously with the auger 6.

[0028] Resetter: The reset member 14 is a T-shaped structure, and its truncated cone-shaped portion is fixedly mounted on the top surface of the reciprocating rod 11. A spring 15 is mounted on its rod-shaped portion. The top surface of the spring 15 is connected to the bottom surface of the bracket 17, and the rod-shaped portion is slidably connected to the hole of the bracket 17. During the rotation and lifting of the reciprocating rod 11, the reset member 14 moves upward, squeezing the spring 15 to store potential energy, and quickly moves downward after the rotating rod 13 passes the highest point.

[0029] The working principle of the utility model is as follows: the linerless label is placed on the guide roller 2 of the base 1, and with the assistance of the conveying component and the material receiving component, the linerless label is driven to be conveyed. During the conveying process, the conveying motor 9 starts to work, the conveying motor 9 drives the worm 8 to rotate, and the worm 8 drives the worm wheel 7 meshing therewith to rotate, thereby making the shaft of the auger 6 coaxial with the worm wheel 7 rotate in the water tank 10 and the glue box 4. When the auger 6 rotates, the glue inside the glue box 4 is conveyed outward through the sleeve 5, so that it falls on the glue roller 3, and the linerless label is glued. In this process, the limit rod 6 inside the slot chamber 61 is used. 4 cooperates with the limiting groove 111 on the reciprocating rod 11, the rotating auger 6 drives the reciprocating rod 11 to rotate synchronously, the reciprocating rod 11 rises and falls in the groove chamber 61 and the water tank 10, and the rotating rod 13 provided thereon cooperates with the guide block 16 to perform the lifting movement, and when climbing, the spring 15 on the reset member 14 is squeezed through the bracket 17 to make it in a squeezed state; at the same time, the limiting block 12 on the reciprocating rod 11 is separated from the protrusion 63, so that the water in the groove chamber 61 and the water tank 10 is discharged through the through hole 62 and enters the sleeve 5, and is evenly mixed during the rotation of the auger 6, thereby improving the fluidity of the glue.
