Description

Technical Field

[0001] The invention relates to the technical field of product packaging and labeling, and in particular to a metal floor conveying and labeling device. Background Art

[0002] In today's industrial manufacturing field, metal flooring is a common and important product widely used in many industries such as construction and decoration. With the rapid development of various industries and the continuous expansion of the market scale, the output of metal flooring is also continuing to rise. In order to facilitate product identification and management and meet various requirements in the market circulation link, it is increasingly important to accurately and standardizedly label metal floors. Labels can carry key information such as product specifications, models, batches, production dates, etc. This information not only helps the internal quality control and inventory management of the production enterprise, but also is an important basis for consumers to understand the characteristics of the product when purchasing it. Therefore, high-quality and efficient metal floor labeling technology is one of the key links to ensure the smooth operation of the entire industrial chain.

[0003] However, most traditional metal floor labeling methods rely on manual operation. Workers need to manually stick labels to metal floors, which has many obvious disadvantages. First, from the efficiency point of view, the speed of manual labeling is limited, and it is difficult to meet the needs of fast labeling under large-scale production. Especially when the output is large, it will greatly slow down the production progress and increase production costs. Secondly, in terms of labeling quality, since manual operation cannot ensure that the label and the surface of the metal floor are evenly bonded each time, it is easy for the label to be loosely attached, have bubbles, wrinkles, etc., which not only affects the appearance of the product, but also may cause the label to fall off prematurely during subsequent handling, storage or use, thereby affecting the integrity and recognizability of the product information. Moreover, it is difficult for manual labeling to adjust the labeling strength and method in a targeted manner for metal floors of different thicknesses and labels with different adhesion requirements. It lacks flexibility and cannot guarantee the stability of the labeling effect.

[0004] In view of the various shortcomings of traditional manual labeling methods, with the continuous advancement and development of industrial automation technology, the market demand for metal floor labeling devices that can be automated, efficient and flexibly adjusted is becoming increasingly urgent. Enterprises hope to replace cumbersome and inefficient manual operations by introducing advanced labeling equipment, improve labeling efficiency, ensure the consistency and stability of labeling quality, and easily cope with the labeling needs of metal floors of different specifications and working conditions, thereby improving the efficiency of the entire production process and the market competitiveness of products. In this context, the development of a new type of metal floor conveying labeling device has important practical significance. Summary of the invention

[0005] The main purpose of the present invention is to provide a metal floor conveying labeling device to realize the automatic labeling operation of the metal floor during the conveying process, improve the labeling efficiency, and at the same time ensure the firmness of the label and the metal floor. It can also flexibly adjust the labeling pressure and other related parameters according to the metal floors of different thicknesses and labels with different adhesion requirements to ensure the consistency and stability of the labeling quality.

[0006] Technical Solution

[0007] The metal floor conveying labeling device of the present invention is mainly composed of a conveying belt, a labeling component and an adjusting component.

[0008] Conveyor belt part: The device is equipped with a conveyor belt, which serves as a conveying carrier for the metal floor. It can stably carry multiple metal floors and convey the metal floors equidistantly at a set speed, providing a stable material transportation basis for subsequent labeling operations.

[0009] Labeling components:

[0010] A mounting seat is vertically arranged on one side of the conveyor belt, and the side wall of the mounting seat is connected to the mounting frame through a fixing rod. The upper and lower ends of the mounting frame are respectively hinged to the label reel and the reel-up reel, between which the label tape is wound, and the top surface of the label tape is adhered with label paper. During the operation of the label tape, the reel-up reel is responsible for reeling the label tape, driving the label paper to move, and realizing continuous labeling.

[0011] A guide rail is also vertically installed on the side wall of the mounting seat, and a sliding seat is slidably sleeved on the guide rail, and the sliding seat is horizontally connected to the connecting frame. A sliding rod is symmetrically installed at the bottom of the connecting frame, and a roller frame is slidably sleeved at the lower part of the sliding rod, and a first spring is sleeved on the outer peripheral surface of the sliding rod. A pressure roller is hinged at the lower end of the roller frame, and the bottom end of the pressure roller rolls against the top of the metal floor being transported. When the label paper moves to the corresponding position with the label belt, the label paper is pressed down by the pressure of the pressure roller to make it fit with the surface of the metal floor, thereby realizing the initial pasting operation.

[0012] The end of the winding disk is coaxially connected to the first rotating rod, and the first rotating rod passes through the mounting seat. The side wall of the mounting seat is also hinged to the second rotating rod. The first rotating rod and the second rotating rod are both sleeved with synchronous wheels, and the two are connected by the same synchronous belt. A turntable is coaxially sleeved on the end of the second rotating rod. A plurality of extrusion protrusions are evenly distributed on the outer circumference of the turntable, and a pressure protrusion is provided on the top of the connecting frame. The top arc surface of the pressure protrusion is slidably abutted with the bottom arc surface of the extrusion protrusion. During the rotation of the winding disk, the turntable rotates synchronously through the transmission of the synchronous wheel and the synchronous belt, and its extrusion protrusion has a continuous striking effect on the pressure protrusion, thereby causing the connecting frame to rise and fall repeatedly. Through the pressure transmission of the first spring, the pressure roller continuously squeezes the label paper, thereby enhancing the firmness of the label adhesion.

[0013] Adjustment assembly: An adjustment assembly is provided on the top of the slide to adjust the pressure of the pressure protrusion. The adjustment assembly includes a screw rod that slides vertically through the upper and lower ends of the slide, a nut is provided on the upper threaded sleeve of the screw rod, a mounting plate is provided at the bottom of the nut, and the mounting plate is fixed to the side wall of the mounting seat. A hand wheel is coaxially provided on the top of the screw rod, and a second spring is provided on the lower end sleeve. By turning the hand wheel, the screw rod can be moved up and down to change the height position of the pressure protrusion, thereby adjusting the pressure intensity and pressure height of the pressure roller, so as to adapt to metal floors of different thicknesses and label papers with different adhesion requirements, and achieve the purpose of flexibly adjusting the labeling effect.

[0014] Auxiliary parts: A peeling rod for peeling labels is slidably inserted into the inner wall of the lower end of the label belt, which can effectively peel the label paper from the label belt when the label belt moves, ensuring that the label paper can be accurately delivered to the surface of the metal floor for pasting. At the same time, a motor is coaxially arranged at the end of the first rotating rod away from the winding disk. The motor provides power for the entire labeling process, drives the winding disk to rotate, drives the label belt to run, and thus starts the entire labeling process.

[0015] When working, first place the metal floor on the conveyor belt, and start the conveyor belt and the motor. The conveyor belt starts to transport the metal floor at a uniform speed, and the motor drives the reel to rotate. The reel reels the label tape. In this process, the peeling rod peels the label paper from the label tape. As the conveyor belt is conveyed, the peeled label paper comes under the pressure roller, and the pressure roller initially sticks the label paper on the metal floor by its own gravity and the pressure of the first spring. At the same time, the rotation of the reel drives the turntable to rotate synchronously through the synchronous wheel and the synchronous belt. The extrusion protrusion on the turntable continuously hits the pressure protrusion on the connecting frame, causing the connecting frame to rise and fall repeatedly. With the help of the pressure transmission of the first spring, the pressure roller continuously squeezes the label paper, further enhancing the pasting effect. In addition, according to actual needs, the position of the screw can be adjusted by turning the hand wheel to change the pressure of the pressure protrusion, and then the pressure of the pressure roller can be adjusted to adapt to different metal floors and label paper conditions.

[0016] Beneficial effects:

[0017] Improve efficiency: The automatic conveying of metal floors and the automation of the entire labeling assembly through the conveyor belt eliminates the need for manual labeling operations one by one, greatly improving the labeling efficiency and meeting the needs of large-scale production.

[0018] Enhanced adhesion firmness: With the help of the rolling contact of the pressure roller and the continuous squeezing effect produced by the cooperation between the turntable and the pressed protrusion, the label paper and the metal floor can be tightly adhered, effectively avoiding the problem of the label falling off easily during subsequent transportation and use, and ensuring the quality of labeling.

[0019] Flexible adaptability: The setting of the adjustment component allows the device to easily and quickly adjust parameters such as the pressure and height of the pressure roller according to metal floors of different thicknesses and label papers with different adhesion requirements. It can flexibly respond to a variety of actual working conditions, ensuring that ideal labeling effects can be achieved in various situations, thereby enhancing the practicality and versatility of the device.

[0020] In summary, the metal floor conveying labeling device of the present invention effectively solves many problems existing in the traditional metal floor labeling method, and has significant practical value and application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Installation and commissioning phase of the device

[0035] Overall assembly

[0036] First, the conveyor belt 1 is laid and fixed according to the predetermined work site requirements to ensure that it can run smoothly and can carry multiple metal floors 2 at equal distances for transportation.

[0037] Next, the mounting base 3 is vertically installed on one side of the conveyor belt 1, and the stability of the mounting base 3 is ensured by a suitable connection method such as bolt connection. Two fixing rods 4 are installed on the side walls of the mounting base 3, and the connection is also ensured to be firm, and then the mounting frame 5 is installed on the ends of the two fixing rods 4, so that the mounting frame 5 can be stably in the working position.

[0038] At the upper end of the mounting frame 5, a label tray 6 is hingedly mounted, and at the lower end, a winding tray 7 is similarly hingedly mounted. Then, the label tape 8 is wound between the label tray 6 and the winding tray 7. It is necessary to ensure that the label tape 8 can be smoothly retracted and released, and that the label paper 9 adhered to the top surface is neatly arranged without wrinkles or damage.

[0039] The guide rail 17 is vertically installed on the side wall of the mounting seat 3 to make it vertical and smooth, and then the slide 18 is sleeved on the guide rail 17 to ensure that the slide 18 can slide up and down flexibly along the guide rail 17, and then the connecting frame 19 is horizontally installed on the slide 18 to ensure a stable connection.

[0040] Two slide bars 20 are symmetrically installed at the bottom of the connecting frame 19, the roller frame 22 is slidably sleeved on the lower part of the slide bar 20, and the first spring 21 is sleeved on the outer circumference of the slide bar 20. The first spring 21 should be of appropriate specifications, and its spring constant is controlled between 1.5N / mm and 3N / mm. Then, a pressure roller 23 is hinged at the lower end of the roller frame 22, and the position of the pressure roller 23 is adjusted so that its bottom end can just roll and abut against the top of the metal floor 2, and in the initial state, a certain initial pressure is given to the pressure roller 23 by relying on the elastic force of the first spring 21 to ensure that there is appropriate contact pressure during subsequent labeling.

[0041] Connect the first rotating rod 12 coaxially to the end of the winding drum 7, and make the first rotating rod 12 pass through the mounting seat 3, hinge the second rotating rod 15 on the side wall of the mounting seat 3, and then respectively put the synchronous wheel 13 on the first rotating rod 12 and the second rotating rod 15, and use the synchronous belt 14 to sleeve and connect the two synchronous wheels 13 to ensure stable transmission and no abnormal conditions such as slipping. Then coaxially sleeve the turntable 16 on the end of the second rotating rod 15 to ensure that the turntable 16 can rotate smoothly with the second rotating rod 15. At the same time, pay attention to the multiple extrusion protrusions 161 distributed at equal distances on the outer circumference of the turntable 16, so that its surface is smooth and has no burrs or other defects that affect the subsequent contact with the compressed protrusion 28. Finally, install the compressed protrusion 28 on the top of the connecting frame 19, and adjust its position so that the top arc surface of the compressed protrusion 28 can slide and abut against the bottom arc surface of the extrusion protrusion 161, and the abutment state is stable and smooth.

[0042] For the adjustment component, the screw rod 25 is slid vertically through the upper and lower ends of the slide seat 18, a nut 26 is threadedly sleeved on the upper part of the screw rod 25, the mounting plate 24 is fixed to the side wall of the mounting seat 3, and then the bottom of the nut 26 is fitted with the mounting plate 24, and a hand wheel 27 is coaxially installed on the top of the screw rod 25, and a second spring 29 is sleeved on the lower end to ensure that all components are reliably connected, and the screw rod 25 can achieve a smooth up and down movement adjustment function by rotating the hand wheel 27.

[0043] Finally, a peeling rod 10 for peeling off the label is slidably inserted into the inner wall of the lower end of the label tape 8, so that it can effectively peel off the label paper 9 during the operation of the label tape 8, and the motor 11 is coaxially installed on the end of the first rotating rod 12 away from the winding drum 7, ensuring that the motor 11 is firmly installed and its output shaft is tightly connected to the first rotating rod 12, which can stably transmit power to drive the winding drum 7 to rotate.

[0044] Debugging

[0045] Turn on the power of the conveyor belt 1 to make it run at a suitable speed, and observe the conveying condition of the metal floor 2 on the conveyor belt to see if there are any abnormal phenomena such as deviation or jamming. If so, timely adjust the relevant parameters of the conveyor belt 1 such as tension and the installation position of each component to ensure that the metal floor 2 can be transported smoothly and at a uniform speed.

[0046] Start the motor 11 and let it drive the take-up reel 7 to rotate slowly, observe the take-up of the label tape 8, and check whether the label tape 8 can be smoothly released from the label reel 6 and orderly taken up by the take-up reel 7. At the same time, pay attention to the peeling effect of the peeling rod 10 on the label paper 9. If it is found that the label paper 9 is not peeled smoothly or is torn, adjust the position of the peeling rod 10 or replace the appropriate peeling rod 10.

[0047] Observe the working status of the pressure roller 23 as the metal floor 2 on the conveyor belt 1 is transported and the winding reel 7 drives the label tape 8 to run, check whether the rolling contact between the pressure roller 23 and the metal floor 2 is uniform and stable, turn the hand wheel 27 by adjusting the screw 25, feel the influence of the change of the pressure of the pressed protrusion 28 on the pressure of the pressure roller 23, and observe the sliding of the connecting frame 19, the slide seat 18 and other components on the guide rail 17 to ensure the coordinated movement of the whole structure, and the first spring 21 and the second spring 29 can play a corresponding buffering and pressure regulating role to ensure that the pressure roller 23 can apply appropriate pressure to the metal floors 2 of different thicknesses to stick the label paper 9.

[0048] Check the transmission conditions of the synchronous wheel 13 and the synchronous belt 14, observe the synchronization of the turntable 16 as it rotates with the winding drum 7, and check whether the contact and cooperation between the extrusion protrusion 161 and the pressure protrusion 28 can produce a continuous striking effect as required by the design, thereby driving the connecting frame 19 to rise and fall repeatedly to achieve dynamic adjustment of the pressure on the pressure roller 23. If problems such as poor synchronization are found, check whether the synchronous wheel 13 is installed coaxially, whether the tension of the synchronous belt 14 is appropriate, etc., and make corresponding adjustments to ensure that the entire transmission system is stable and reliable, and can achieve the function of enhancing the label pasting effect.

[0049] Normal working stage

[0050] Metal floor conveying and label stripping

[0051] When everything is debugged normally, the metal floor 2 to be labeled is placed on the conveyor belt 1 at an equal distance as required, and the conveyor belt 1 and the motor 11 are started, and the conveyor belt 1 starts to uniformly convey the metal floor 2. The motor 11 drives the first rotating rod 12 to rotate, and then drives the winding reel 7 to rotate and rewind the label tape 8. As the label tape 8 moves, under the action of the peeling rod 10, the label paper 9 is peeled off from the label tape 8 in an orderly manner, ready for subsequent pasting.

[0052] Initial labeling

[0053] The peeled label paper 9 moves with the metal floor 2 on the conveyor belt 1 and comes under the pressure roller 23. At this time, relying on the gravity of the pressure roller 23 itself and the initial pressure given by the first spring 21, the pressure roller 23 rolls and abuts against the top of the metal floor 2, pressing the label paper 9 downward so that it is initially adhered to the surface of the metal floor 2. In this process, due to the rolling characteristics of the pressure roller 23, it can ensure that the label paper 9 and the surface of the metal floor 2 are adhered relatively smoothly, and there will be no bubbles or other conditions that affect the pasting quality.

[0054] Enhanced pasting effect

[0055] While the winding disk 7 is rotating continuously, the second rotating rod 15 is also rotating synchronously through the transmission of the synchronous belt 14 and the synchronous wheel 13, driving the rotating disk 16 at its end to rotate. The extrusion protrusions 161 on the outer peripheral surface of the rotating disk 16 will continuously slide and abut against the pressure protrusions 28 on the top of the connecting frame 19 as the rotating disk 16 rotates. Since the extrusion protrusions 161 are distributed at equal distances, they will produce a continuous striking effect on the pressure protrusions 28. The struck pressure protrusions 28 will cause the connecting frame 19 to continuously rise and fall in the vertical direction along the sliding rod 20. Through the pressure transmission of the first spring 21 on the sliding rod 20, the pressure roller 23 will obtain a continuous squeezing effect, thereby further increasing the squeezing force on the label paper 9, making the label paper 9 and the metal floor 2 more tightly attached, effectively improving the firmness of the label attachment, and avoiding the label from falling off during subsequent transportation and use.

[0056] Adjust pressure to suit different situations

[0057] If it is necessary to label metal floors 2 of different thicknesses or label papers 9 with different adhesion requirements, the operation can be adjusted by turning the hand wheel 27 during the operation of the equipment. When the hand wheel 27 is turned clockwise, the screw rod 25 will move downward along the nut 26. Because the nut 26 is fixed on the mounting plate 24 and relatively stationary, the lower end of the screw rod 25 will squeeze the pressed protrusion 28, increasing the contact pressure between the pressed protrusion 161, and then through the action of the connecting frame 19, the sliding rod 20 and the first spring 21, the pressure of the pressure roller 23 on the metal floor 2 is increased; on the contrary, when the hand wheel 27 is turned counterclockwise, the screw rod 25 moves upward, the pressure of the pressed protrusion 28 is reduced, and the pressure of the pressure roller 23 on the metal floor 2 is also reduced. In this way, the pressure and pressure height of the pressure roller 23 can be flexibly adjusted according to the actual situation to meet the diverse labeling needs and ensure that each labeling can achieve the ideal pasting effect.

[0058] Through the above detailed implementation, the metal floor conveying labeling device can complete the labeling work of the metal floor efficiently, stably and with high quality, and can be flexibly adjusted according to actual conditions to adapt to different production requirements.

[0059] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0060] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
