Description

Technical Field

[0001] The invention relates to the field of label gluing, in particular to label processing and gluing equipment with a residual glue recovery function. Background Art

[0002] Labels are tools used to mark product targets, categories or contents, so that you and others can find and locate targets. Most of the labels in the printing industry are printed materials used to mark product-related instructions. Labels with glue are commonly known as "self-adhesive labels", and the glue in self-adhesive labels is mostly rubber-type adhesives and hot-melt adhesives. Among them, hot-melt adhesives have fast curing speed, high bonding strength, good environmental protection, good flexibility and easy use, and are widely used in self-adhesive labels.

[0003] The Chinese invention discloses a sticker surface gluing device for label production (application number: 202420951094X), in which glue is added into the storage barrel through the inlet, and when gluing, the glue drips into the inside of the holding rack through the outlet, and the storage barrel and the holding rack are rotatably connected through the placement round rod and the control round rod on the storage barrel. When the device runs for a certain period of time, the storage barrel can be controlled to rotate and shake inside the holding rack through the crank, and the glue inside the storage barrel is inspected, shaken and mixed to avoid the glue having a high viscosity blocking the glue outlet and affecting the coating of the sticker;

[0004] However, the above device can only apply glue to liquid glue, but is difficult to apply glue to hot-melt adhesive. Moreover, when applying glue through the dispersing roller under the receiving rack, the glue in the receiving rack easily falls through the gaps on both sides of the dispersing roller, causing contamination to the label to be glued.

[0005] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0011] Preferably, the flanges at both ends of the cooling roller are provided with fixedly connected rotating joints, the threaded barrel in the mounting plate is provided with a threaded hand screw, and one end of the hand screw is provided with a rotatably connected mounting block.

[0012] Preferably, a fixedly connected strap is provided above the first mounting block, the strap is placed above the L-shaped frame and is slidably connected to the L-shaped frame, and a fixedly connected scraper is provided below the first mounting block.

The flanges at both ends of the cooling roller 2 are also fixed with rotating joints by bolts. The rotating joints at one end of the cooling roller 2 and the cooling roller 1 are connected by connecting hoses and are internally connected. A water pump is placed on one side of the frame, and the water outlet of the water pump is fixedly connected to the pipe at one end of one of the connecting hoses and is internally connected.

[0015] Preferably, the interior of the frame is further provided with four pinch rollers distributed in an array, two of the pinch rollers distributed transversely are rotationally connected to each other through a synchronous belt and a synchronous pulley, and two of the pinch rollers distributed longitudinally are rotationally connected through the meshing of spur gears, the stepper motor 2 is fixedly connected to the shaft at one end of one of the pinch rollers, and a rotatably connected guide roller is also provided inside the frame.

[0019] 2. The present invention also starts stepper motor 1 and stepper motor 2. When stepper motor 1 is started, it drives the lower glue coating roller, the upper glue coating roller and the cooling roller 1 to rotate simultaneously through the synchronous belt and gears. The lower glue coating roller transports the glue in the glue groove to the outside of the upper glue coating roller, and then the upper glue coating roller coats the glue under the face paper. At the same time, the cooling roller 1 cools the face paper during glue coating, so as to quickly solidify the glue under the face paper. By driving the lower glue coating roller, the upper glue coating roller and the cooling roller 1 to rotate synchronously through the stepper motor 1, the transmission ratio between the lower glue coating roller, the upper glue coating roller and the cooling roller 1 can be accurately determined to prevent the problem of damage to the glued face paper due to inconsistent transmission ratios.

The two pinch rollers 33 distributed laterally are rotationally connected to the synchronous pulley through a synchronous belt, and the two pinch rollers 33 distributed longitudinally are rotationally connected through the meshing of spur gears. A stepper motor 2 41 is fixedly installed on one side of the frame 31 by bolts. The stepper motor 2 41 is fixedly connected to the shaft at one end of one of the pinch rollers 33. When the stepper motor 2 41 is started, it drives the four pinch rollers 33 to rotate. The interior of the frame 31 is also provided with a rotatably connected guide roller 37.

[0042] A bottom paper roll 38 is also provided inside the frame 31, and a mounting roller 381 is provided inside the bottom paper roll 38. The bottom paper roll 38 is installed on the outside of the mounting roller 381. Fixed bearings 382 are provided at both ends of the mounting roller 381. The bearings 382 are located inside the placement groove 311 to reduce the friction force when the bottom paper roll 38 rotates.

The end of the placement groove 311 close to the electric push rod 39 is lower than the end away from the electric push rod 39. When the electric push rod 39 is started, it drives the push block 40 to move. When the push block 40 moves, it pushes the mounting roller 381 to move to the side away from the electric push rod 39, thereby realizing the unloading of the bottom paper roll 38.

[0043] The working process and principle of this application are as follows:

[0044] Step 1: put the hot-melt adhesive stick or adhesive block to be used into the adhesive groove 1, then start the electric heating rod 15 to heat and melt the adhesive block. After the adhesive block in the adhesive groove 1 is melted, start the electric push rod 1 27 to drive the mounting frame 2 28 to lift, and the mounting frame 28 drives the sliding plate 29 and the cooling roller 19 to lift. At this time, the label surface paper passes between the upper adhesive roller 18 and the cooling roller 19;

[0045] Step 2: At this time, the water pump 36 is started, and the water pump 36 delivers cooling water to the cooling roller 19 and the cooling roller 2 32 through one of the connecting hoses 35, thereby achieving a cooling treatment for the cooling roller 19 and the cooling roller 2 32, and then the bottom paper roll 38 is placed in the placement groove 311 in the frame 31, and the surface paper and the bottom paper in the bottom paper roll 38 are pulled to the position as shown in FIG. Figure 8 As shown, the electric push rod 27 is started again to drive the cooling roller 19 to press down until it contacts the surface paper of the label;

[0046] Step 3: Turn the hand screw 20 to adjust the distance between the scraper blade 23 and the upper glue roller 18, so as to adjust the glue thickness of the label. After the adjustment is completed, start the stepper motor 16 and the stepper motor 2 41. When the stepper motor 16 is started, the lower glue roller 17, the upper glue roller 18 and the cooling roller 19 are driven to rotate simultaneously through the synchronous belt and the gear. At this time, the lower glue roller 17 and the upper glue roller 18 rotate in the same direction, and the upper glue roller 18 and the cooling roller 19 rotate in the opposite direction. The lower glue roller 17 transports the glue in the glue groove 1 to the outer side of the upper glue roller 18, and then the upper glue roller 18 applies the glue to the bottom of the face paper. At the same time, the cooling roller 19 cools down the face paper during gluing, so as to quickly solidify the glue under the face paper. After the face paper passes between the upper glue roller 18 and the cooling roller 19, it continues to cool down through the cooling roller 2 32, and then passes between the pinch rollers 33 to fit with the base paper.
