Description

Technical Field

[0001] The utility model relates to the technical field of labeling machines, and particularly relates to a label pressing mechanism of a labeling machine. Background Art

[0002] After the production and processing of packaging material products, they all need to be labeled to facilitate their search or identification. When labeling, a labeling machine is required. A labeling machine is a device that can paste a roll of self-adhesive paper labels (paper or metal foil) on a PCB, a product, or a specified package.

[0003] Application No.: CN202322479572.X discloses a label pressing mechanism of a labeling machine. In this label pressing mechanism of the labeling machine, when the electric telescopic rod extends, the electric telescopic rod drives the moving plate to move downward. The moving plate drives the rolling cylinder in the rolling frame to move downward through the sliding rod. The rolling cylinder contacts and rolls on the label on the packaging material, and through the acting force of the spring, the two sliding rods push the rolling cylinder in the rolling frame to roll-press the label on the packaging material, so that the label on the packaging material can be pressed more firmly, effectively preventing the label from bulging, and well ensuring the normal labeling of the packaging material.

[0004] The existing patented technology presses the label on the packaging material by setting an electric telescopic rod to drive the rolling cylinder. However, this label pressing structure uses a single cylinder, and the contact time of the single cylinder with the label is short, which cannot ensure that the edge of the label and the packaging material are tightly compacted. At the same time, when the electric fan in the existing patented technology blows towards the rolling cylinder, it will blow dust towards the edge of the label and the packaging material, affecting the pressing of the label, resulting in poor adhesion effect of the label on the packaging material after being pressed, and thus poor labeling effect of the packaging material. For this reason, we propose a label pressing mechanism of a labeling machine. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a label pressing mechanism of a labeling machine. After installing an electric push rod on the support at the conveyor used in the labeling machine, the electric push rod can cooperate with the bottom connecting plate to install a supplementary pressing mechanism to form a label pressing mechanism. This label pressing mechanism continuously presses the packaging material conveyed on the surface of the conveyor through a double-channel label pressing roller, so that the label on the surface of the packaging material can be pressed tightly; and there is a structure for blowing air downward between the double-channel label pressing rollers, so that there is a downward cooling and drying wind force when the label is pressed, ensuring that the label can be quickly cured on the surface of the packaging material after being pressed. Compared with the opposite blowing of the electric fan in the existing patented technology, the downward blowing fan of the utility model will not affect the edge warping position when the label is pressed, nor will it blow dust under the label, and can effectively solve the problems in the background art.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] Further, the bottom box body of the triangular guide box welded below the bridge is higher than the roller pressing position of the label pressing roller;

[0009] By adopting the above technical solution, when the label pressing roller is installed at the L-shaped main support plate and the L-shaped auxiliary support plate below the bridge for downward pressing, the bottom box body of the triangular guide box will not contact the packaging materials and labels conveyed on the surface of the conveyor belt inside the conveyor.

[0010] Further, the upper box mouth of the triangular guide box is in communication with the base mouth of the support mouth seat, and the bottom box mouth of the triangular guide box is a strip-shaped box mouth;

[0011] By adopting the above technical solution, after the air enters at the support mouth seat, the air can enter the triangular guide box along the support mouth seat and blow downward.

[0012] Further, two sets of roller bodies of the label pressing roller are clamped between the L-shaped main support plate and the L-shaped auxiliary support plate and their respective supplementary plates, and screw holes for screwing bolts are provided between the L-shaped main support plate and the L-shaped auxiliary support plate and their respective supplementary plates;

[0013] By adopting the above technical solution, the L-shaped main support plate and the L-shaped auxiliary support plate cooperate with the supplementary plate to install two sets of roller bodies of the label pressing roller, so that the electric push rod can push the two sets of label pressing rollers to continuously supplement the pressure on the label on the surface of the packaging material.

[0014] Further, a main rotation hole is provided in the middle of the L-shaped main support plate, and a main rotation bolt is screwed upward into the bottom connecting plate and the telescopic rod head of the electric push rod below the main rotation hole;

[0015] By adopting the above technical solution, the L-shaped main support plate is strengthened by screwing the main rotation bolt into the bottom connecting plate and the telescopic rod head of the electric push rod.

[0016] Furthermore, a screw hole is provided on the upper seat surface of the support socket away from its upper seat opening, and a bolt is screwed between the screw hole of the support socket and the seat plate mounting hole of the blower;

[0017] By adopting the above technical solution, there is a screw hole at the support socket that can cooperate with the seat plate mounting hole of the blower for bolt locking installation.

[0018] Compared with the prior art, the present utility model has the following beneficial effects:

[0019] After the present utility model is provided with a bracket to install an electric push rod at the conveyor for a labeling machine, the electric push rod can cooperate with the bottom connecting plate to install a supplementary pressing mechanism to form a label pressing mechanism.

[0020] Moreover, there is a structure for blowing air downward between the double-channel label pressing rollers, so that there is a downward cooling and drying wind force when the label is pressed, ensuring that the label can be quickly solidified on the surface of the packaging material after being pressed.

[0028] As Figures 1-4As shown in the figure, a label pressing mechanism of a labeling machine includes a conveyor 1, a bracket 2 and an electric push rod 3. The bracket 2 is installed on the base of the conveyor 1, and the electric push rod 3 is installed on the upper shelf plate of the bracket 2 close to its own slot.

The supplementary pressing mechanism 5 includes an L-shaped main support plate 6, a bridge 8, an L-shaped auxiliary support plate 9, a supplementary plate 10, a label pressing roller 13, a triangular guide box 15 and a fan 17. The bottom connecting plate 4 is locked on the upper plate surface of the L-shaped main support plate 6 by bolts, and the upper plate surface of the L-shaped main support plate 6 away from the bottom connecting plate 4 is welded to the L-shaped auxiliary support plate 9 through the bridge 8. The other end plate bodies of the L-shaped main support plate 6 and the L-shaped auxiliary support plate 9 away from their vertical plates are locked with a supplementary plate 10 with a supplementary hole 11 on the surface by bolts, and support holes 12 are opened at the vertical plates of the L-shaped main support plate 6 and the L-shaped auxiliary support plate 9. The shaft heads 14 fixed at both ends of the label pressing roller 13 are clamped in the holes of the supplementary hole 11 and the support hole 12. A triangular guide box 15 is welded below the bridge 8 between the L-shaped main support plate 6 and the L-shaped auxiliary support plate 9, and a support mouth seat 16 is welded in communication with the upper box mouth of the triangular guide box 15. The fan 17 is locked on the surface of the support mouth seat 16 by bolts. The bottom box mouth of the triangular guide box 15 faces the surface of the conveyor belt inside the conveyor 1.

[0029] Among them, the bottom box body of the triangular guide box 15 welded below the bridge 8 is higher than the rolling position of the label pressing roller 13;

[0030] By adopting the above technical solution, when the label pressing roller 13 is installed at the L-shaped main support plate 6 and the L-shaped auxiliary support plate 9 below the bridge 8 for downward pressing, the bottom box body of the triangular guide box 15 will not contact the packaging materials and labels conveyed on the surface of the conveyor belt inside the conveyor 1.

[0031] Among them, the upper box mouth of the triangular guide box 15 is in communication with the base mouth of the support mouth seat 16, and the bottom box mouth of the triangular guide box 15 is a strip-shaped box mouth;

[0032] By adopting the above technical solution, after the air enters at the support mouth seat 16, the air can enter the triangular guide box 15 along the support mouth seat 16 and blow downward.

[0033] Among them, two groups of roller bodies of the label pressing roller 13 are clamped between the L-shaped main support plate 6 and the L-shaped auxiliary support plate 9 and their respective supplementary plates 10, and screw holes for screwing bolts are opened between the L-shaped main support plate 6 and the L-shaped auxiliary support plate 9 and their respective supplementary plates 10;

[0034] By adopting the above technical solution, the L-shaped main support plate 6 and the L-shaped auxiliary support plate 9 cooperate with the supplementary plate 10 to install two groups of roller bodies of the label pressing roller 13, so that the electric push rod 3 can push the two groups of label pressing rollers 13 to continuously supplement the pressure on the labels on the surface of the packaging materials.

[0035] Among them, a main rotation hole 7 is opened in the middle of the L-shaped main support plate 6, and a main rotation bolt 701 screws upward into the telescopic rod head of the bottom connection plate 4 and the electric push rod 3 below the main rotation hole 7;

[0036] By adopting the above technical solution, at the L-shaped main support plate 6, the main rotation bolt 701 is screwed into the telescopic rod head of the bottom connection plate 4 and the electric push rod 3 for strengthened connection.

[0037] Among them, a screw hole is opened on the upper seat surface of the support mouth seat 16 away from its own upper seat mouth, and a bolt is screwed between the screw hole of the support mouth seat 16 and the seat plate mounting hole of the fan 17;

[0038] By adopting the above technical solution, there is a screw hole at the support mouth seat 16 that can cooperate with the seat plate mounting hole of the fan 17 for bolt locking installation.

[0039] It should be noted that the present utility model is a label pressing mechanism of a labeling machine. After installing the electric push rod 3 on the support 2 at the conveyor 1 used in the labeling machine, the electric push rod 3 can cooperate with the bottom connection plate 4 to install the L-shaped main support plate 6 of the supplementary pressing mechanism 5. Then, the L-shaped main support plate 6 welds the triangular guide box 15 and the L-shaped auxiliary support plate 9 through the bridge 8. At this time, the shaft head 14 of the label pressing roller 13 can be clamped at the support holes 12 of the L-shaped main support plate 6 and the L-shaped auxiliary support plate 9. Then, the supplementary plate 10 provided with the supplementary hole 11 is clamped towards the other end shaft head of the label pressing roller 13, and the supplementary plate 10 is locked at the L-shaped main support plate 6 and the L-shaped auxiliary support plate 9 with bolts for installation. At the same time, the fan 17 is locked above the support mouth seat 16 with bolts. When the fan 17 is powered on, a connecting wire with a lifting distance needs to be reserved, which is convenient for the fan 17 to lift and lower with the support mouth seat 16 and the triangular guide box 15. When the packaging material is labeled on the surface and then placed on the surface of the conveyor 1 for label pressing, the electric push rod 3 can be controlled to extend its telescopic rod. At this time, the L-shaped main support plate 6, the L-shaped auxiliary support plate 9, and the triangular guide box 15 descend in height. Then, the label pressing roller 13 at the L-shaped main support plate 6 and the L-shaped auxiliary support plate 9 can press down to contact the label on the surface of the packaging material, so that the label is continuously pressed by the two label pressing rollers 13. And the dry air blown from the fan 17 can be blown towards the label, prompting the label to dry and stick tightly to the surface of the packaging material and not easy to fall off. Then, the electric push rod 3 can drive the supplementary pressing mechanism 5 to rise away from the label and the packaging material.
