Description

Technical Field

[0001] The utility model relates to the technical field of labeling equipment, in particular to a labeling equipment which is convenient for replacing a label paper roll. Background Art

[0002] With the development of society, various products are gradually increasing, so products need to be classified by labeling for easy identification. Traditionally, labeling paper for items is manually applied. When the number of products is large, according to the traditional operation method, a lot of manpower is needed to label the products after they are processed. Therefore, automatic labeling equipment has emerged. However, after the roll label on the bearing is affixed, a new label roll needs to be replaced. At this time, the support plate, bolts and other components on one side need to be removed and the roll needs to be put in. After putting it in, the above steps need to be repeated again. It is time-consuming and labor-intensive, so a labeling equipment that is easy to replace the label paper roll has emerged.

[0003] For example, an existing patent (publication number: CN211766882U) discloses a labeling device that is convenient for replacing label paper rolls. The device facilitates the replacement of label paper rolls by setting a limit cover, a side plate and a fixed rod. After the labels on the label paper roll are used up, the limit cover is unscrewed, the paper roll is removed, and a new paper roll is placed on the fixed rod. The limit cover and the fixed rod are threadedly connected. Screwing on the limit cover prevents the paper roll from deviating and facilitates the replacement of the paper roll.

[0004] However, the above-mentioned labeling device for facilitating replacement of label paper rolls still has some disadvantages in actual use: the labeling device for facilitating replacement of label paper rolls uses a limit cover to limit the label paper roll, and although the limit cover can be used in conjunction with the threaded connection for disassembly during use, it is more convenient than the bolt flange connection in the prior art, but the above-mentioned operation still requires a lot of manual participation from personnel, which is still inconvenient when the bolts are densely packed, or the thread slippage problem is prone to occur when the thread is damaged.

[0005] Therefore, we have designed a labeling device that is easy to replace label paper rolls to solve the above problems. Utility Model Content

[0006] The purpose of the present invention is to provide a labeling device that is convenient for replacing label paper rolls, so as to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the utility model provides a labeling device that is convenient for replacing label paper rolls, including a side plate, a fixed shaft is fixedly installed on one side of the side plate, a paper roll is movably sleeved on the fixed shaft, a metal plate is slidably arranged in the fixed shaft, a limit rod and a first spring are fixedly installed on the top of the metal plate, the first spring is movably sleeved on the limit rod, the other ends of the limit rod and the first spring are both arranged in the fixed shaft, an electromagnet is fixedly installed on the bottom of the fixed shaft, the electromagnet is magnetically connected to the metal plate, and the top end of the limit rod slides through the fixed shaft and cooperates with one end of the paper roll to resist.

[0008] Furthermore, a cavity is provided in the fixed shaft, the metal plate is slidably connected in the cavity, a sliding opening is provided at the top of the fixed shaft, the cavity and the sliding opening are connected, the top end of the limit rod is slidably inserted in the sliding opening, and when retracted into the cavity, the top end of the limit rod is flush with the side surface of the fixed shaft to prevent motion interference problems when placing or taking.

[0009] Furthermore, a storage groove is provided on the fixed shaft, a first electromagnetic button is fixedly installed at the bottom of the storage groove, a slider is slidably provided in the storage groove, and one side of the slider is against the paper tube.

[0010] Furthermore, one side of the slider is an inclined surface for cooperating with the paper tube to slide backward on the fixed shaft. The setting of the inclined surface of the slider ensures that the paper tube will not cause motion interference when it is pushed backward.

[0011] Furthermore, a fixing rod and a second spring are fixedly installed at the bottom of the slider, the second spring is movably sleeved on the fixing rod, the other end of the second spring is fixedly connected to the bottom of the storage slot, and the fixing rod cooperates with the first electromagnetic button to resist each other. When the slider moves downward, it will drive the second spring to resist the first electromagnetic button and press the first electromagnetic button to send an electrical signal to the electromagnet to disconnect.

[0012] Furthermore, a second electromagnetic button and a battery are provided on the side panel. The battery is electrically connected to the first electromagnetic button, the second electromagnetic button and the electromagnet, and the second electromagnetic button is electrically connected to the electromagnet.

[0013] Furthermore, the first electromagnetic button is electrically connected to the electromagnet, the bottom of the slider cooperates with and abuts against the first electromagnetic button, and the first electromagnetic button is electrically connected to the metal plate. During movement, the first electromagnetic button can be pressed by the thrust of the paper tube on the slider.

[0014] Furthermore, the other end of the second spring is fixedly connected to the bottom of the storage slot, and the fixing rod cooperates with the first electromagnetic button to abut against it.

[0015] Compared with the prior art, the beneficial effect of the present invention is as follows: before placing a new paper roll, pressing the second electromagnetic button to power the electromagnet makes the electromagnet have magnetic force, and due to the magnetic force, the metal plate and the electromagnet attract each other, the metal plate slowly moves downward and stretches the first spring, and drives the limit rod to move downward and reset in the cavity, when the metal plate and the electromagnet are magnetically fitted, the top of the limit rod is flush with the side surface of the fixed shaft, avoiding the problem of motion interference when placing and taking, when the coil is placed, the limit rod is slid out of the fixed shaft according to the above principle and against the paper roll to limit it, and in this process, there is less manual participation of personnel and it is more convenient.

[0016] When the paper tube slides to the bottom of the fixed shaft and abuts against one side of the side plate, the fixed rod cooperates with the first electromagnetic button to abut against it. The first electromagnetic button sends an electrical signal to turn off the electromagnet, causing it to lose its magnetism and release the magnetic adhesion. At this time, due to the elastic rebound of the first spring itself, the limiting rod slides out of the sliding mouth and abuts against the other end of the paper tube, which can further reduce manual intervention of personnel, thereby further improving the convenience of disassembly and assembly.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-3The utility model provides a technical solution: it includes a side panel 1, a fixed shaft 2 is fixedly installed on one side of the side panel 1, a paper tube 3 is movably sleeved on the fixed shaft 2, a metal plate 6 is slidably arranged in the fixed shaft 2, a limiting rod 8 and a first spring 9 are fixedly installed on the top of the metal plate 6, the first spring 9 is movably sleeved on the limiting rod 8, the other ends of the limiting rod 8 and the first spring 9 are both arranged in the fixed shaft 2, an electromagnet 7 is fixedly installed on the bottom of the fixed shaft 2, the electromagnet 7 is magnetically connected to the metal plate 6, the top end of the limiting rod 8 slides through the fixed shaft 2 and cooperates with one end of the paper tube 3.

[0023] A cavity 4 is defined in the fixed shaft 2 , a metal plate 6 is slidably connected in the cavity 4 , a sliding opening 5 is defined on the top of the fixed shaft 2 , the cavity 4 and the sliding opening 5 are communicated, and the top end of the limiting rod 8 is slidably inserted in the sliding opening 5 .

[0024] During specific implementation, before placing a new paper tube 3, the second electromagnetic button 16 is pressed to power the electromagnet 7 so that the electromagnet 7 has magnetic force. At this time, due to the influence of magnetic force, the metal plate 6 and the electromagnet 7 attract each other, the metal plate 6 slowly moves downward and stretches the first spring 9, and drives the limit rod 8 to move downward and reset in the cavity 4. When the metal plate 6 and the electromagnet 7 are magnetically fitted, the top of the limit rod 8 is flush with the side surface of the fixed shaft 2, avoiding the problem of motion interference when placing and taking; when the first electromagnetic button 14 sends an electrical signal to turn off the electromagnet 7, making it lose its magnetism and release the magnetic fit with the metal plate 6, at this time, due to the elastic rebound of the first spring 9 itself, the limit rod 8 slides out of the sliding mouth 5 and abuts against the other end of the paper tube 3, playing a role of fixed clamping to prevent the paper tube 3 from deviating and improve stability during use.

[0025] See Figure 1-3 As shown, a storage groove 12 is also provided on the fixed shaft 2, and a first electromagnetic button 14 is fixedly installed at the bottom of the storage groove 12. A slider 10 is slidably provided in the storage groove 12, and one side of the slider 10 is against the paper tube 3. The first electromagnetic button 14 is electrically connected to the electromagnet 7, and the bottom of the slider 10 cooperates with the first electromagnetic button 14 to abut against it.

[0026] One side of the slider 10 is an inclined surface, which is used to cooperate with the paper tube 3 to slide backward on the fixed shaft 2.

[0027] A fixing rod 11 and a second spring 13 are fixedly installed at the bottom of the slider 10. The second spring 13 is movably sleeved on the fixing rod 11. The other end of the second spring 13 is fixedly connected to the bottom of the storage slot 12. The fixing rod 11 cooperates with the first electromagnetic button 14 to resist each other.

[0028] In specific implementation, when the paper tube 3 on the fixed shaft 2 is pushed backward, the end of the paper tube 3 is against the inclined surface of the slider 10. During the pushing process, the slider 10 compresses the second spring 13 and moves it downward. When the paper tube 3 slides to the bottom of the fixed shaft 2 and is against one side of the side plate 1, the fixed rod 11 cooperates with the first electromagnetic button 14 to abut against it. At this time, the first electromagnetic button 14 sends an electrical signal to turn off the electromagnet 7, avoiding manual closing, reducing work steps, and improving work efficiency. During use, the staff is less required to manually debug the equipment throughout the process, which increases convenience during use.

[0029] See Figure 1-3 A second electromagnetic button 16 and a battery 15 are also provided on the side panel 1. The battery 15 is electrically connected to the first electromagnetic button 14, the second electromagnetic button 16 and the electromagnet 7, and the second electromagnetic button 16 is electrically connected to the electromagnet 7. The setting of the second electromagnetic button 16 can make it more convenient for the staff to manually adjust the descent of the limit rod 8, improve the ease of use, and save time and effort when changing the paper roll 3 roll, and the electrical connection between the two makes the connection between them more stable.

[0030] Working principle: The battery 15 supplies power to the appliance. Before placing a new paper tube 3, press the second electromagnetic button 16 to supply power to the electromagnet 7, which makes the electromagnet 7 have magnetic force. At this time, due to the influence of magnetic force, the metal plate 6 and the electromagnet 7 attract each other, and the metal plate 6 slowly moves downward and stretches the first spring 9, and drives the limit rod 8 to move downward and reset in the cavity 4. When the metal plate 6 and the electromagnet 7 are magnetically fitted, the top of the limit rod 8 is flush with the side surface of the fixed shaft 2, avoiding the problem of motion interference when placing and taking; when the paper tube 3 on the fixed shaft 2 is pushed backward, the end of the paper tube 3 is against the inclined surface of the slider 10, and the slider 10 is pushed during the pushing process. 0 compresses the second spring 13 and moves it downward. When the paper tube 3 slides to the bottom of the fixed shaft 2 and abuts against one side of the side plate 1, the fixed rod 11 cooperates with the first electromagnetic button 14 to abut against it. The first electromagnetic button 14 sends an electrical signal to turn off the electromagnet 7, causing it to lose its magnetism and release the magnetic fit with the metal plate 6. At this time, due to the elastic rebound of the first spring 9 itself, the limiting rod 8 slides out of the sliding mouth 5 and abuts against the other end of the paper tube 3, playing a role of fixing and clamping to prevent the paper tube 3 from deviating and improve stability during use. If the tube core needs to be removed, just repeat the above steps. During use, the staff rarely needs to manually debug the equipment, which increases the convenience of use.

[0031] A conveyor is placed under the fixed shaft 2 to transport the labeled items. The conveyor usually includes a motor, a transmission belt and two rotating rollers. The rotating rollers are rotatably set on the frame, and the belt tensioning sleeve is set on the rotating rollers. Then the motor is connected to one of the rotating rollers. Turning on the motor can rotate the rotating roller, thereby moving the transmission belt. Since the conveyor is a prior art, it will not be described in detail in this manual.
