Description

Technical Field

[0001] This utility model belongs to the field of label winding technology, and in particular relates to a self-adhesive label winding roller. Background Technology

[0002] In the production of self-adhesive labels, a take-up roller is usually required to wind the labels. However, existing take-up rollers are typically mounted on a shaft, which then drives the roller to rotate and wind the labels. During the winding process, the labels are only wound onto the roller by the tension generated during winding. This method can easily cause the wound labels to become loose, resulting in the labels not being tightly wound after the roller is removed, causing them to detach from the roller and fall off, requiring subsequent sorting by staff. Therefore, we have proposed a self-adhesive label take-up roller. Utility Model Content

[0003] The purpose of this invention is to provide a self-adhesive label winding roller. By setting a pressing component, specifically, after the winding roller is installed, pressing the pressure rod downwards causes the diamond-shaped spring to disengage from the square groove. The pressure rod then moves downwards and contacts the label wound on the surface of the winding roller, pressing the label with its own weight. Thus, the label is subjected to pressure during winding, making the winding tighter and improving the winding effect. This significantly reduces the occurrence of labels scattering after winding, solving the problem that in existing winding rollers, the wound labels tend to become loose after winding, resulting in insufficiently tight winding and labels detaching from the roller and scattering.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a self-adhesive label winding roller, including a winding section for fixing the roller and winding the labels; and...

[0006] The pressing part is installed above the winding part and is used to press the winding label.

[0007] The winding section is used to connect to the drive device, so that the winding section rotates to wind up the label.

[0008] Furthermore, the winding section includes a rotating shaft, a limiting protrusion is fixedly connected to the bottom of the rotating shaft, a winding drum is sleeved on the outside of the rotating shaft, and the rotating shaft is used to connect to a motor through a coupling, thereby driving the rotating shaft to rotate;

[0009] A clamping assembly, installed inside the rotating shaft, for clamping and fixing the take-up drum; and

[0010] A limiting component is installed behind the clamping component and is used to limit the clamping component when it is clamped.

[0011] The clamping assembly, after clamping the take-up drum, is able to position the axis of the take-up drum relative to the axis of the rotating shaft.

[0012] Furthermore, the pressing part includes a positioning component for adjusting the position and installing on take-up drums of different lengths;

[0013] The pressing assembly is mounted above the rotating shaft and is used to press the labels wound on the take-up drum.

[0014] The positioning component, after adjustment, is used to limit and position the winding drum during installation.

[0015] Furthermore, the positioning component includes a positioning ring slidably connected to the outside of the rotating shaft, a support rod is provided above the positioning ring, a positioning groove is provided at the bottom of the inner side of the positioning ring, three grooves are provided on the inner side of the positioning ring, a connecting plate is fixedly connected to the back of the positioning ring, and a threaded knob is threadedly connected inside the connecting plate; the grooves are provided to leave space for the extrusion block so that the extrusion block can expand smoothly.

[0016] The positioning groove on the positioning ring is slidably connected to the limiting protrusion to limit the positioning ring. The threaded knob contacts the surface of the rotating shaft by rotating clockwise to fix the positioning ring. The support rod is used to connect to the external bracket, fix the pressing component above the rotating shaft and support the pressing component.

[0017] Furthermore, the pressing assembly includes a fixed frame fixedly connected to the front of the support rod. Two limiting vertical rods are slidably connected inside the fixed frame. A pressure rod is fixedly connected to the bottom of the limiting vertical rod. A diamond-shaped spring piece is fixedly connected to the center of the top of the pressure rod. A square groove is opened at the center of the fixed frame. The limiting vertical rod is used to limit the pressure rod, so that the pressure rod moves in a linear manner. The limiting vertical rod is connected to the pressure rod by welding.

[0018] The limiting vertical rod is square in shape and is used to limit the pressure rod. The pressure rod is round in shape to reduce friction on the label. The pressure rod is inserted into the square groove through a diamond-shaped spring to fix the pressure rod to the bottom of the fixing frame.

[0019] Furthermore, the clamping assembly includes a threaded rod threaded to the front of the rotating shaft, a handle fixedly connected to the front of the threaded rod, a push plate fixedly connected to the back of the threaded rod, and three extrusion blocks slidably connected to the outside of the rotating shaft. Each extrusion block has a limiting groove inside. The three extrusion blocks can expand or contract simultaneously. When expanding simultaneously, they clamp and fix the winding drum, so that the axis of the winding drum corresponds to the axis of the rotating shaft.

[0020] The extrusion block is inclined on the side facing the pusher and is in contact with the surface of the pusher. The extrusion block corresponds to the groove. When the pusher moves backward, it is used to push the extrusion block.

[0021] Furthermore, the limiting assembly includes a fixing rod fixedly connected to the back of the inner wall of the rotating shaft. Three limiting rods are fixedly connected to the outer surface of the fixing rod. The limiting rods pass through the extrusion block and extend into the limiting groove. A spring is fixedly connected to the side of the limiting rod away from the fixing rod. The side of the spring away from the limiting rod is fixedly connected to the inner wall of the limiting groove. The extrusion block will retract and reset under the elastic action of the spring, releasing the fixing of the winding drum and facilitating the disassembly of the winding drum.

[0022] The limiting rod is used to limit the extrusion block, and the extrusion block will stretch the limiting groove when it expands outward. The limiting groove is used to retract and reset the extrusion block through elastic force.

[0023] This utility model has the following beneficial effects:

[0024] 1. This utility model, by setting up a pressing component, specifically, after the winding drum is installed, the pressing rod is pressed down to make the diamond-shaped spring piece disengage from the square groove. Then the pressing rod moves downward and contacts the label wound on the surface of the winding drum. The label is pressed down by its own weight. Thus, the label can be subjected to pressure during winding, thereby making the winding more compact and improving the winding effect. This can significantly reduce the occurrence of labels falling off after winding.

[0025] 2. This utility model, by setting up a clamping component, specifically, involves placing the take-up drum on the rotating shaft. Rotating the handle clockwise causes the threaded rod to rotate, which in turn drives the push plate to move to the back. The push plate simultaneously pushes the three extrusion blocks, clamping and fixing the take-up drum. This method can position the take-up drum at the center of the rotating shaft and can install and fix take-up drums of different sizes. Moreover, it can be quickly fixed by rotation, which is more efficient.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0036] Please see Figures 1-5 As shown, this utility model is a self-adhesive label rewinding roller, including a winding section 1 for fixing the roller and winding the labels; and

[0037] Pressing part 2 is installed above the winding part 1 and is used to press the winding label.

[0038] The winding section 1 is used to connect to the drive device, so that the winding section 1 rotates to wind up the label.

[0039] The winding section 1 includes a rotating shaft 11, with a limiting protrusion 111 fixedly connected to the bottom of the rotating shaft 11, and a winding drum 12 sleeved on the outside of the rotating shaft 11. The rotating shaft 11 is used to connect to a motor through a coupling, thereby driving the rotating shaft 11 to rotate.

[0040] Clamping assembly 13, installed inside the rotating shaft 11, is used to clamp and fix the take-up drum 12; and

[0041] Limiting component 14 is installed behind clamping component 13 and is used to limit the clamping component 13 when it is clamped.

[0042] The clamping assembly 13, after clamping the take-up drum 12, is able to position the axis of the take-up drum 12 and the axis of the rotating shaft 11.

[0043] The pressing part 2 includes a positioning component 21, which is used to adjust the position and install on take-up drums 12 of different lengths;

[0044] Pressing component 22 is installed above the rotating shaft 11 and is used to press the labels wound on the take-up drum 12.

[0045] The positioning component 21, after adjustment, is used to limit and position the installation position of the winding drum 12.

[0046] The positioning assembly 21 includes a positioning ring 211 slidably connected to the outside of the rotating shaft 11, a support rod 212 is provided above the positioning ring 211, a positioning groove 213 is provided at the bottom of the inner side of the positioning ring 211, three grooves 214 are provided on the inner side of the positioning ring 211, a connecting plate 215 is fixedly connected to the back of the positioning ring 211, and a threaded knob 216 is threadedly connected inside the connecting plate 215.

[0047] The positioning groove 213 on the positioning ring 211 is slidably connected to the limiting protrusion 111 to limit the positioning ring 211. The threaded knob 216 contacts the surface of the rotating shaft 11 by rotating clockwise to fix the positioning ring 211. The support rod 212 is used to connect to the external bracket, fix the pressing component 22 above the rotating shaft 11 and support the pressing component 22.

[0048] The pressing component 22 includes a fixed frame 221 fixedly connected to the front of the support rod 212. Two limiting vertical rods 222 are slidably connected inside the fixed frame 221. A pressure rod 223 is fixedly connected to the bottom of the limiting vertical rod 222. A diamond-shaped spring piece 224 is fixedly connected to the top center of the pressure rod 223. A square groove 225 is opened at the center of the fixed frame 221.

[0049] The limiting vertical rod 222 is square and is used to limit the pressure rod 223. The pressure rod 223 is round and is used to reduce friction on the label. The pressure rod 223 is inserted into the square groove 225 through the diamond-shaped spring piece 224 to fix the pressure rod 223 to the bottom of the fixing frame 221. After the winding drum 12 is installed, the pressure rod 223 is pressed down, so that the diamond-shaped spring piece 224 is disengaged from the square groove 225. Then the pressure rod 223 moves downward and contacts the label wrapped on the surface of the winding drum 12. The label is pressed down by its own weight. The label is subjected to pressure during winding, so the winding is tighter and the winding effect is improved. This can greatly reduce the occurrence of labels falling off after winding.

[0050] The clamping assembly 13 includes a threaded rod 131 threadedly connected to the front of the rotating shaft 11, a handle 132 fixedly connected to the front of the threaded rod 131, a push plate 133 fixedly connected to the back of the threaded rod 131, and three extrusion blocks 134 slidably connected to the outside of the rotating shaft 11. Limiting grooves 135 are formed inside the extrusion blocks 134.

[0051] The extrusion block 134 is inclined on the side facing the push plate 133 and contacts the surface of the push plate 133. The extrusion block 134 corresponds to the groove 214. When the push plate 133 moves backward, it pushes the extrusion block 134. The take-up drum 12 is sleeved on the rotating shaft 11. The clockwise rotation of the handle 132 drives the threaded rod 131 to rotate. The threaded rod 131 drives the push plate 133 to move backward. The push plate 133 pushes the three extrusion blocks 134 at the same time, clamping and fixing the take-up drum 12. This method can position the take-up drum 12 at the center of the rotating shaft 11 and can install and fix take-up drums 12 of different sizes. It can be quickly fixed by rotation, which is more efficient.

[0052] The limiting assembly 14 includes a fixing rod 141 fixedly connected to the back of the inner wall of the rotating shaft 11. Three limiting rods 142 are fixedly connected to the outer surface of the fixing rod 141. The limiting rods 142 pass through the extrusion block 134 and extend into the limiting groove 135. A spring 143 is fixedly connected to the side of the limiting rod 142 away from the fixing rod 141. The side of the spring 143 away from the limiting rod 142 is fixedly connected to the inner wall of the limiting groove 135.

[0053] The limiting rod 142 is used to limit the extrusion block 134, and the extrusion block 134 will stretch the limiting groove 135 when it expands outward. The limiting groove 135 is used to retract and reset the extrusion block 134 through elastic force.

[0054] One specific application of this embodiment is:

[0055] In use, adjust the position of the positioning ring 211 according to the length of the take-up drum 12. First, turn the threaded knob 216 counterclockwise to release the fixing of the positioning ring 211. Then, push and pull the positioning ring 211 to adjust it to the appropriate position. The positioning ring 211 then slides on the limiting protrusion 111 through the positioning groove 213, causing the positioning ring 211 to move linearly. After the positioning ring 211 is adjusted, turn the threaded knob 216 clockwise to make it contact the surface of the rotating shaft 11, thereby fixing the positioning ring 211. Then, put the take-up drum 12 onto the rotating shaft 11, and... Make the back of the take-up drum 12 contact the front of the positioning ring 211, and then turn the handle 132 clockwise to drive the threaded rod 131 to rotate. The threaded rod 131 drives the push plate 133 to move to the back. The push plate 133 pushes the three extrusion blocks 134 at the same time, and the extrusion blocks 134 slide on the limit rod 142, while stretching the spring 143. When the extrusion blocks 134 contact the inner wall of the take-up drum 12, they will clamp and fix the take-up drum 12. This method can position the take-up drum 12 at the center of the rotating shaft 11 and can install and fix take-up drums 12 of different sizes.

[0056] After the take-up drum 12 is installed, the label is wrapped around the take-up drum 12. Then, the pressure bar 223 is pressed down, causing the diamond-shaped spring piece 224 to disengage from the square groove 225. When not in use, the pressure bar 223 is inserted into the square groove 225 through the diamond-shaped spring piece 224, fixing the pressure bar 223 to the bottom of the fixing frame 221, which facilitates the installation of the take-up drum 12. When the diamond-shaped spring piece 224 disengages from the fixing frame 221, the pressure bar 223 moves downward and contacts the label wrapped on the surface of the take-up drum 12. It presses the label down by its own weight, so that the label can be subjected to pressure during winding, making the winding tighter. As the winding continues to increase, the pressure bar 223 is pushed upward, and the limiting vertical bar 222 slides on the fixing frame 221 to limit the pressure bar 223, so that the pressure bar 223 moves in a straight line.

[0057] After the final winding is completed, pull the pressure rod 223 upward so that the diamond-shaped spring piece 224 is inserted into the square groove 225, thereby fixing the pressure rod 223. Then, turn the handle 132 counterclockwise to drive the threaded rod 131 to rotate, causing the push plate 133 to move forward. The extrusion block 134 will retract and reset under the elastic action of the spring 143, releasing the fixing of the winding drum 12. Finally, pull the winding drum 12 out.
