Description

Technical Field

[0001] This utility model relates to a label smoothing mechanism for an automatic printing and labeling machine, belonging to the field of labeling machine technology. Background Technology

[0002] In the field of automated label application, labeling machines use smoothing rollers to roll and squeeze labels, effectively eliminating air bubbles and wrinkles between the label and the product surface. This is a key component to ensure the flatness and firmness of the label application. However, during long-term continuous production, adhesives such as hot melt adhesives, water-based adhesives, and solvent-based adhesives on the back of the label may transfer to the surface of the smoothing roller due to uneven coating, pressure overflow, or label edge damage. Under the influence of continuous friction and ambient temperature, these residual adhesives gradually solidify and accumulate, forming hard adhesive blocks or sticky coatings. The solidified adhesive blocks will scratch the label surface during the smoothing process, causing label damage and peeling of the printed layer, directly affecting the product's appearance quality. Existing smoothing mechanisms mainly rely on manual wiping during machine shutdowns to clean adhesive residue from the smoothing rollers. This method is inefficient, difficult to completely remove, and frequent shutdowns can affect production continuity. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a label smoothing mechanism for an automatic printing and labeling machine, which facilitates quick cleaning of the smoothing roller.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an automatic printing and labeling machine label smoothing mechanism, characterized in that it includes: a mounting frame, an mounting plate is vertically arranged inside the mounting frame, and a slot is opened on the mounting plate. A movable block is arranged in the slot, and a motor and a smoothing roller are respectively arranged at both ends of the movable block. The output end of the motor is connected to the smoothing roller. A cleaning cylinder is fixed through the side of the mounting frame, and cleaning cotton is attached to the bottom of the inner wall of the cleaning cylinder. The smoothing roller and the cleaning cylinder are arranged horizontally.

[0005] The mounting frame is also equipped with a lateral movement mechanism for driving the mounting plate to move laterally;

[0006] A spraying mechanism is provided on the top of the mounting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] By incorporating a lateral movement mechanism, a cleaning cylinder, and a spraying mechanism, the smoothing roller can be cleaned without shutting down the machine. The lateral movement mechanism moves the mounting plate laterally, allowing the smoothing roller to enter the cleaning cylinder. The spraying mechanism sprays cleaning agent onto the surface of the smoothing roller. Combined with the friction between the roller and the cleaning cotton caused by the rotation of the motor, adhesive residue is quickly removed. No manual wiping is required, avoiding the impact of frequent shutdowns on production continuity and significantly improving cleaning efficiency.

Detailed Implementation

[0020] 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 protection scope of the present utility model.

[0021] Please see Figs. 1-3 This utility model provides a technical solution:

[0022] An automatic label printing and labeling machine label smoothing mechanism includes: a mounting frame 1, an mounting plate 2 vertically arranged inside the mounting frame 1, and a slot is provided on the mounting plate 2. A movable block 3 is arranged in the slot, and a motor 4 and a smoothing roller 5 are respectively arranged at both ends of the movable block 3. The output end of the motor 4 is connected to the smoothing roller 5. A cleaning cylinder 8 is fixed through the side of the mounting frame 1, and cleaning cotton 9 is attached to the bottom of the inner wall of the cleaning cylinder 8. The smoothing roller 5 and the cleaning cylinder 8 are arranged horizontally.

[0023] The mounting bracket 1 is also equipped with a lateral movement mechanism 10 for driving the mounting plate 2 to move laterally;

[0024] The top of the mounting bracket 1 is equipped with a spray mechanism 12.

[0025] Furthermore, the movable block 3 on the mounting plate 2 carries the motor 4 and the smoothing roller 5. The motor 4 drives the smoothing roller 5 to rotate to complete the label smoothing operation. The lateral movement mechanism 10 can drive the mounting plate 2 to move laterally, so that the smoothing roller 5 can be switched into the cleaning cylinder 8. Together with the cleaning cotton 9 and the spraying mechanism 12, automatic cleaning can be achieved, removing the glue residue on the roller surface without stopping the machine, thus balancing labeling efficiency and cleaning effect.

[0026] In this embodiment: vertical rods 6 are fixed at both ends of the interior of the empty groove, and the vertical rods 6 pass through both ends of the movable block 3 and are slidably connected to it. A spring 7 is sleeved on the vertical rod 6, and the two ends of the spring 7 are respectively connected to the movable block 3 and the inner wall of the empty groove.

[0027] Furthermore, the vertical rod 6 within the slot of the mounting plate 2 provides a vertical sliding guide for the movable block 3, and the spring 7 sleeved on the vertical rod 6 utilizes elastic deformation to achieve buffering. When the smoothing roller 5 contacts the product surface, if it encounters a protrusion or positional misalignment causing excessive pressure, the movable block 3 will slide along the vertical rod 6 and compress the spring 7, automatically adjusting the pressure to prevent label deformation and product damage, while ensuring uniform smoothing pressure and improving label flatness.

[0028] In this embodiment: the transverse movement mechanism 10 includes a second motor 1001, which is fixed to the side of the mounting frame 1, and the output end of the second motor 1001 is connected to the lead screw 1002. The lead screw 1002 is arranged transversely in the upper part of the mounting frame 1, and a guide rod 1003 is also fixed in the upper part of the mounting frame 1. Both the lead screw 1002 and the guide rod 1003 penetrate the mounting plate 2.

[0029] Furthermore, motor 1001 drives lead screw 1002 to rotate, and lead screw 1002 cooperates with mounting plate 2 to drive its lateral movement. Guide rod 1003 restricts the offset and rotation of mounting plate 2, so that smoothing roller 5 can stably enter cleaning cylinder 8 to complete cleaning, or return to the working position for labeling, ensuring the stability and accuracy of work position switching.

[0030] In this embodiment: a conveyor belt 11 is provided on the inner bottom of the mounting frame 1.

[0031] Furthermore, the conveyor belt 11 is used to transport the products to be labeled, so as to realize the continuous feeding of the products.

[0032] In this embodiment: the spraying mechanism 12 includes a water tank 1201, which is fixed to the top of the mounting frame 1. A delivery pump 1202 is provided on the side of the water tank 1201. The delivery pump 1202 is connected to the spray pipe 1203 through a delivery pipe. The spray pipe 1203 is installed on the top of the inner wall of the cleaning cylinder 8.

[0033] Furthermore, the water tank 1201 stores cleaning agent, and the delivery pump 1202 pumps the cleaning agent through the delivery pipe to the spray pipe 1203. The spray pipe 1203 sprays the cleaning agent onto the smoothing roller 5 that enters the cleaning cylinder 8, softening the residual glue on the roller surface. Combined with the friction of the cleaning cotton 9, the cleaning is more thorough and avoids the glue from hardening and accumulating, which affects the labeling quality.

[0034] In this embodiment: the cleaning cotton 9 is semi-circular, and the cleaning cotton 9 is connected to the inner wall of the cleaning cylinder 8 by Velcro.

[0035] Furthermore, the semi-circular cleaning cotton 9 can fit tightly against the surface of the smoothing roller 5, increasing the contact area to improve the friction cleaning effect. It is connected to the inner wall of the cleaning cylinder 8 by Velcro, allowing the cleaning cotton 9 to be quickly disassembled and replaced, simplifying the maintenance process and reducing the cost of later use.

[0036] The workflow of this embodiment is as follows: When the product to be labeled is conveyed to the smoothing station via the conveyor belt 11 at the bottom inner side of the mounting frame 1, motor 4 drives the smoothing roller 5 to rotate, rolling and squeezing the label on the product surface to eliminate air bubbles and wrinkles. At this time, the movable block 3 in the slot of the mounting plate 2 floats vertically along the vertical rod 6, and with the elastic buffering effect of the spring 7, the smoothing roller 5 can automatically adjust the pressure according to the curvature or thickness of the product surface, ensuring tight adhesion and avoiding excessive pressure that could deform the label or damage the product. When it is necessary to clean the glue residue on the surface of the smoothing roller 5 after long-term use, motor 1001 is started to drive the lead screw 1002 to rotate, causing the mounting plate 2 and the smoothing roller 5 to move laterally, so that the smoothing roller 5 accurately enters the cleaning cylinder 8 on the side of the mounting frame 1. After entering the cleaning cylinder 8, the cleaning agent in the water tank 1201 is pressurized by the delivery pump 1202 and sent to the spray pipe 1203 at the top of the inner wall of the cleaning cylinder 8 through the delivery pipe. The cleaning agent is sprayed onto the surface of the rotating smoothing roller 5 to soften the residual glue. At the same time, the semi-circular cleaning cotton 9 at the bottom of the inner wall of the cleaning cylinder 8 is in close contact with the surface of the smoothing roller 5. Through friction, the softened glue residue is thoroughly removed. After cleaning is completed, the transverse mechanism 10 is driven in the reverse direction, so that the mounting plate 2 drives the smoothing roller 5 back to the smoothing position to continue the label smoothing operation.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
