Description

Technical Field

[0001] This application relates to the field of labeling device technology, specifically to a self-adhesive barcode paper positioning and labeling device. Background Technology

[0002] Barcode paper, also known as label paper, can be printed with relevant information as needed. Labeling products provides consumers with comprehensive information about the product, allowing them to quickly understand it. Currently, products are generally labeled using labeling machines.

[0003] Existing labeling machines have certain problems in use. When labeling cylindrical items (such as wine bottles and condiment jars), the labeling machine generally uses a peeling plate to peel off the label paper. The label paper is driven and adheres to the two surfaces of the peeling plate. During the transmission process, the label paper is always in contact with the surfaces of the peeling plate, causing one part of the label paper to bend during transmission. This bending state is used to separate the label from the paper, thereby sticking the end of the label to the item. Then, the drive mechanism drives the item to rotate, thereby covering the surface of the item with the label. Because the label is separated from the label paper by bending, the initial detached end of the label is prone to curling up, which makes it easy for wrinkles or curling edges to occur when it comes into contact with the item, resulting in poor label adhesion quality and easy detachment. Therefore, this application proposes a self-adhesive barcode paper positioning and labeling device. Summary of the Invention

[0004] The purpose of this application is to provide a self-adhesive barcode paper positioning and labeling device in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution:

[0006] A self-adhesive barcode paper positioning and labeling device, comprising:

[0007] The frame is equipped with a transmission mechanism, which is used to transport products and can position, rotate and support the products.

[0008] A mounting plate is provided on one side of the frame. One end of the mounting plate is rotatably equipped with two vertically distributed placing rollers, and the other end is equipped with a conical plate.

[0009] A mounting bracket is mounted on a mounting plate and located below a conical plate. A shaft is rotatably mounted on the mounting bracket. A transfer cylinder is coaxially mounted at one end of the shaft. An inner cylinder is coaxially mounted inside the transfer cylinder. An annular cavity is left between the transfer cylinder and the inner cylinder. Several air holes communicating with the annular cavity are arrayed through the outer surface of the transfer cylinder. Several partitions arranged in a ring are arrayed inside the annular cavity to divide the annular cavity into several air chambers.

[0010] The negative pressure mechanism, mounted on the mounting bracket, is used to create negative pressure by evacuating air from several air chambers.

[0011] Furthermore, the transmission mechanism includes two transmission rollers rotatably mounted on the frame, each of which is fixed with a sprocket at both ends. Four sprockets are paired, and chains are wound around two corresponding sprockets. Several support rollers are arranged in an array between the two chains and along their transmission direction.

[0012] Furthermore, the negative pressure mechanism includes a rotary joint mounted on a mounting bracket. One end of the rotary joint is connected to an air plate, and the air plate is arrayed with several conduits, each of which is connected to several air chambers. The other end of the rotary joint is connected to a delivery pipe. An exhaust fan is mounted on the mounting plate, and the free end of the delivery pipe is connected to the exhaust port of the exhaust fan.

[0013] Furthermore, the inner wall of the inner cylinder has several grooves that communicate with several air chambers. The inner wall of the inner cylinder is provided with several U-shaped frames, each corresponding to one of the grooves. A guide rod is slidably mounted on the U-shaped frame. One end of the guide rod is provided with a block that engages with the groove, and the other end is provided with a limiting plate. A spring is installed between the limiting plate and the U-shaped frame and sleeved on the guide rod. A forcing element is provided on the transfer cylinder. When the transfer cylinder rotates, the forcing element is used to press the guide rod located in the lowest air chamber to slide, thereby relieving the negative pressure inside.

[0014] Furthermore, the forcing member includes a mounting rod disposed on the mounting bracket, the free end of the mounting rod coaxially and movably passing through the shaft and placed inside the inner cylinder, the free end of the mounting rod being connected to a pressure plate via a connecting rod, the pressure plate abutting and overlapping with the limiting plate.

[0015] Furthermore, the mounting plate is provided with a fixing frame, the fixing frame is provided with an electric push rod, the mounting frame is located at the piston end of the electric push rod, and the mounting frame is provided with a guide rod whose end moves through the fixing frame.

[0016] Furthermore, a rotating roller is rotatably mounted on the frame, and a linkage is mounted on the frame. When the shaft rotates, the linkage drives the rotating roller to rotate synchronously in the opposite direction.

[0017] Furthermore, the linkage includes a first vertical rod rotatably mounted on the frame, a second vertical rod movably inserted at the top of the first vertical rod, a first bevel gear fixed at the ends of the first and second vertical rods that are far apart from each other, a second bevel gear fixed on the shaft and the rotating roller, the two second bevel gears meshing with the teeth of the two first bevel gears respectively, a support plate fixed on the mounting frame, and the free end of the support plate rotatably connected to the second vertical rod.

[0018] Furthermore, the mounting frame is equipped with a fan hood, which has an arc-shaped structure and is coaxially arranged with the transfer cylinder. The air outlet of the exhaust fan is connected to the fan hood by a guide pipe.

[0019] Furthermore, a heating cylinder mounted on a mounting plate is connected to the feed tube, and an electric heating wire is installed inside the heating cylinder.

[0020] The beneficial effects of this application are as follows:

[0021] 1. In this application, a cone plate is used to make the label paper bend when it passes the tip of the cone plate. The label paper is peeled off by the bend. Then, a transfer cylinder is used in conjunction with the cone plate to rotate and resist the label paper. A negative pressure mechanism is used to create negative pressure in the transfer cylinder to adsorb the peeled label. The label is first adsorbed on the surface of the transfer cylinder. Then, the rotation of the transfer cylinder is used to cover the label onto the surface of the item. This ensures that the edges of the label will not wrinkle or curl up, thus ensuring the label application effect.

[0022] 2. In this application, by setting up the groove and the insert, the insert is driven to move by the forcing element, thereby actively relieving the negative pressure of the air chamber. Combined with the adhesiveness of the label itself, the label is transferred and applied to the surface of the item more smoothly, thereby improving its practicality.

[0023] 3. In this application, the rotating roller and the transfer cylinder rotate synchronously in opposite directions under the linkage of the linkage component. The two apply two forces with opposite directions of rotation to the item, making the item rotate more smoothly, the label application smoother, and the label transfer and adhesion effect better.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0036] like Figures 1-10 As shown, one embodiment of this application discloses a self-adhesive barcode paper positioning and labeling device, comprising:

[0037] The frame 1 is equipped with a transmission mechanism 2, which is used to transport products and can position, rotate and support the products.

[0038] Mounting plate 3 is located on one side of frame 1. Two vertically arranged placement rollers 4 are rotatably mounted on one end of mounting plate 3, and a conical plate 5 is located on the other end. Preferably, the lower placement roller 4 holds the roll of label paper, and the upper placement roller 4 holds the roll of recycled release paper. The label paper roll is placed on the lower placement roller 4, and its end is wrapped around the conical plate 5 and then connected to the recycled roll. When the two placement rollers 4 rotate, the label paper is conveyed. When the label paper passes the tip of the conical plate 5, it bends, thus peeling off the label. It should be noted that the label is peeled off from the bottom end of the conical plate 5, with the adhesive side facing upwards. Mounting frame 6 is located on mounting plate 3 and below conical plate 5. A shaft 7 is rotatably mounted on mounting frame 6. Figure 5As shown, a motor is installed on the mounting frame 6. The output shaft of the motor is connected to the shaft 7 via a bevel gear assembly. The motor can drive the shaft 7 to rotate. A transfer cylinder 8 is coaxially installed at one end of the shaft 7. Preferably, the tip of the cone plate 5 is located at the middle of the upper end of the transfer cylinder 8. When the label paper is being transferred, the outer surface of the transfer cylinder 8 rotates and contacts the label paper. An inner cylinder 9 is coaxially installed inside the transfer cylinder 8. An annular cavity is left between the transfer cylinder 8 and the inner cylinder 9. Several air holes 10 communicating with the annular cavity are arrayed through the outer surface of the transfer cylinder 8. Several partitions 11 arranged in a ring are arrayed inside the annular cavity, which are used to divide the annular cavity into several air chambers; negative pressure mechanism 1 2. The device is mounted on the mounting frame 6 and is used to create negative pressure by evacuating several air chambers. When labeling items, the items are placed on the conveying mechanism 2 for transport, and the label paper is transported on two rollers 4. When the label paper reaches the tip of the cone plate 5, the label gradually detaches from the paper at the end. Simultaneously, under the action of the motor, the transfer cylinder 8 rotates, creating rotational resistance with the label. The negative pressure mechanism 12 evacuates air from several air chambers, creating negative pressure within them. Since the outer surface of the transfer cylinder 8 has air holes 10 communicating with the air chambers, the negative pressure acts on the label through the air holes 10. Because the label is gradually detaching at this time, the negative pressure... In this process, the label, with the side without adhesive, adheres to the outer surface of the transfer cylinder 8. The process primarily involves bending and peeling, supplemented by negative pressure adsorption. As the label paper is transported and the transfer cylinder 8 rotates, the label is gradually detached from the paper and attached to the transfer cylinder 8. When the item is directly below the transfer cylinder 8, the transport mechanism 2 stops transporting, while the transfer cylinder 8 continues to rotate. The transfer cylinder 8 rotates and overlaps with the outer surface of the item. Because the transport mechanism 2 can position and support the item, the item rotates under the rotational stress of the transfer cylinder 8. This rotation, combined with the rotation of the transfer cylinder 8, causes the two items to rotate synchronously in opposite directions, thus adhering the adhesive side of the label to the item. On the surface, after the adhesive side of the label is applied to the surface of the item, the adhesive properties of the glue force the label to detach from the transfer cylinder 8, thus completing the label transfer. The overall structure of the device uses the cone plate 5 to bend and peel off the label. During the peeling process, negative pressure is used to adhere the label to the surface of the transfer cylinder 8, so that the corners of the label adhere to the transfer cylinder 8 after peeling. The label is then transferred and applied to the item through the transfer cylinder 8, allowing the label to be applied smoothly and evenly without any wrinkles or curling at the corners. At the same time, the transfer cylinder 8 also applies a certain rolling resistance pressure to the label when transferring the label, making the label adhere more tightly to the surface of the item, thereby improving the adhesion quality of the label.

[0039] like Figure 3As shown, in some embodiments, the transmission mechanism 2 includes two transmission rollers 201 rotatably mounted on the frame 1. The two transmission rollers 201 are located at both ends of the frame 1, and sprockets 202 are fixed at both ends of each transmission roller 201. Chains 203 are wound around two corresponding sprockets 202. A plurality of support rollers 204 are arranged in an array between the two chains 203 and along their transmission direction. When transmitting items, the items are placed on two adjacent support rollers 204. Preferably, the support rollers 204 include components connected to... The roller between the two chains 203 has a roller sleeve rotatably fitted on its outer surface. The item is placed on the two roller sleeves. The transfer roller 201 rotates under the action of the motor, thereby causing the chain 203 to transfer the item. During the transfer process, the cylindrical item will not be displaced due to the inertia of the transfer. When the item is transferred to the bottom of the transfer cylinder 8, when the transfer mechanism 2 stops, the item can rotate between the two support rollers 204 under the rotational resistance of the transfer cylinder 8, thereby cooperating with the transfer cylinder 8 to attach the label to the surface of the item.

[0040] like Figure 2 , Figure 4 and Figure 6 As shown, in some embodiments, the negative pressure mechanism 12 includes a rotary joint 1201 mounted on the mounting bracket 6. One end of the rotary joint 1201 is connected to an air plate 1202, and a plurality of conduits 1203 are arrayed and connected on the air plate 1202, with each conduit 1203 connected to a plurality of air chambers. The other end of the rotary joint 1201 is connected to a delivery pipe 1204. An exhaust fan 1205 is mounted on the mounting plate 3, and the free end of the delivery pipe 1204 is connected to the exhaust port of the exhaust fan 1205 for ventilation. When the machine 1205 performs its work, it evacuates the air chamber through the delivery pipe 1204. When the label is attached to the outer surface of the transfer cylinder 8, the label will cover and block the air holes 10 connected to part of the air chamber, thereby creating negative pressure in this part of the air chamber. At this time, the air holes 10 in the part of the air chamber are not covered by the label, so that they can be ventilated normally to meet the normal ventilation requirements of the exhaust fan 1205. Through the set rotary joint 1201, the delivery pipe 1204 and the exhaust fan 1205 will not interfere with the normal rotation of the transfer cylinder 8.

[0041] like Figure 10As shown, in some embodiments, the inner wall of the inner cylinder 9 has several grooves 13 that communicate with several air chambers respectively. The inner wall of the inner cylinder 9 is provided with several U-shaped frames 14, each corresponding to one of the grooves 13. A guide rod 15 is slidably mounted on the U-shaped frame 14. One end of the guide rod 15 is provided with a block 16 that is inserted into and cooperates with the groove 13, and the other end is provided with a limiting plate 17. A spring 18 is installed between the limiting plate 17 and the U-shaped frame 14 and sleeved on the guide rod 15. A forcing member 19 is provided on the transfer cylinder 8. When the transfer cylinder 8 rotates, the forcing member... 19 is used to press the guide rod 15, located in the lowest air chamber, to slide and release the negative pressure inside. Preferably, both the insert 16 and the groove 13 are conical. In the initial state, under the elastic force of the spring 18, the insert 16 is embedded in the groove 13, thereby sealing the groove 13. As the transfer cylinder 8 rotates, when the transfer cylinder 8 comes into contact with the surface of the object, the point of contact is directly below the transfer cylinder 8. At this time, the forcing member 19 drives the guide rod 15 to slide downward, thereby causing the limiting plate 17 to squeeze the spring 18, thus causing the insert 16 to disengage from the groove 13. The state at this time is as follows. Figure 10 As shown, the air chamber is connected to the inner cylinder 9, thereby relieving the negative pressure state of the air chamber. As the transfer cylinder 8 continues to rotate, the lowest air chamber will change position, forcing the component 19 to no longer apply resistance to the guide rod 15. Under the elastic force of the spring 18, the guide rod 15 moves upward and resets, so that the insert 16 is inserted into the groove 13 again, which facilitates the subsequent negative pressure generated by the exhaust fan 1205 to adsorb the subsequent labels. By using the component 19 to depressurize the air chamber located at the lowest position, combined with the adhesiveness of the glue, the labels can be more smoothly detached from the transfer cylinder 8 and adhered to the surface of the item, thereby improving practicality.

[0042] like Figure 5 , Figure 6 and Figure 10 As shown, in some embodiments, the forcing member 19 includes a mounting rod 1901 disposed on the mounting bracket 6, such as Figure 5 As shown, an L-shaped rod is provided on the mounting bracket 6, and a mounting rod 1901 is mounted on the L-shaped rod. The free end of the mounting rod 1901 coaxially and movably passes through the shaft rod 7 and is placed inside the inner cylinder 9. The free end of the mounting rod 1901 is connected to a pressure plate 1903 through a connecting rod 1902. The pressure plate 1903 abuts and overlaps with the limiting plate 17, as shown. Figure 6 and Figure 10As shown, the pressure plate 1903 is located directly below the mounting rod 1901. Since the mounting rod 1901 moves through the shaft 7, even if the shaft 7 and the transfer cylinder 8 rotate, the pressure plate 1903 will always be located directly below. As the transfer cylinder 8 rotates, the limiting plate 17 at the end of the guide rod 15 at the bottom will come into contact with the pressure plate 1903. It should be noted that the limiting plate 17 is constructed with an arc-shaped head, and the pressure plate 1903 is constructed with an arc-shaped plate. The arc-shaped surface of the limiting plate 17 comes into contact with the arc-shaped surface of the pressure plate 1903. Under the action of the arc-shaped surface, the guide rod 15 is driven to slide downward.

[0043] like Figure 7 As shown, in some embodiments, a fixing frame 20 is provided on the mounting plate 3, an electric push rod 21 is provided on the fixing frame 20, and a mounting bracket 6 is provided at the piston end of the electric push rod 21. A guide rod 22 with its end movable through the fixing frame 20 is provided on the mounting bracket 6. When the electric push rod 21 does work, its piston end drives the mounting bracket 6 to move vertically, thereby adjusting the position of the transfer cylinder 8. In actual use, the transfer cylinder 8 only picks up one label at a time. After the label is transferred to the item, the subsequent labels are picked up. By vertically adjusting the position of the transfer cylinder 8, not only can the rotational resistance pressure of the transfer cylinder 8 and the cone plate 5 on the label paper be ensured, but the rotational resistance pressure of the transfer cylinder 8 and the item on the label paper can also be adjusted, making the label more effective and stable when it is detached from the release paper. At the same time, the label is also more effective and stable when it is transferred from the transfer cylinder 8 to the item.

[0044] like Figure 1 and Figure 3 As shown, in some embodiments, a rotating roller 23 is rotatably mounted on the frame 1, and a linkage 24 is mounted on the frame 1. When the shaft 7 rotates, the linkage 24 drives the rotating roller 23 to rotate synchronously in the opposite direction. Through the rotating roller 23, as shown... Figure 3 As shown, it can effectively support the items. Through the linkage of the linkage component 24, the rotating roller 23 can rotate synchronously in the opposite direction with the transfer cylinder 8, so that the items are subjected to rotational stress in two directions, making the items rotate more smoothly and the label transfer and adhesion effect better.

[0045] like Figure 9As shown, in some embodiments, the linkage 24 includes a first vertical rod 2401 rotatably mounted on the frame 1, and a second vertical rod 2402 movably inserted into the top of the first vertical rod 2401. Preferably, the first vertical rod 2401 and the second vertical rod 2402 are splined together. Under the action of the spline, the second vertical rod 2402 can slide axially along the inside of the first vertical rod 2401, but cannot rotate freely in a circular motion. When the second vertical rod 2402 rotates, it can drive the first vertical rod 2401 to rotate synchronously. A first bevel gear 2403 is fixedly mounted at the ends of the first vertical rod 2401 and the second vertical rod 2402 that are far apart from each other. A second bevel gear 2404 is fixedly mounted on the shaft 7 and the rotating roller 23. The two second bevel gears 2404 mesh with the teeth of the two first bevel gears 2403 respectively. A support plate 2405 is fixedly mounted on the mounting frame 6. The free end of the support plate 2405 is rotatably connected to the second vertical rod 2402. The support plate 2405 and the second vertical rod The rotating connection of 2402 allows the support plate 2405 to drive the second vertical rod 2402 to move vertically without interfering with the normal rotation of the second vertical rod 2402. When the shaft 7 rotates, the meshing of the teeth of one of the first bevel gears 2403 and the second bevel gear 2404 can drive the first vertical rod 2401 and the second vertical rod 2402 to rotate synchronously. Then, through the meshing of the teeth of the other first bevel gear 2403 and the second bevel gear 2404, the rotating roller 23 is driven to rotate synchronously. Since the two first bevel gears 2403 are arranged opposite to each other, the rotating roller 23 and the shaft 7 rotate synchronously in opposite directions. In the overall structure of the device, the first vertical rod 2401 and the second vertical rod 2402 act as a telescopic rod, and the meshing of the teeth of the first bevel gear 2403 and the second bevel gear 2404 acts as a transmission component, so that no matter how the positions of the transfer cylinder 8 and the shaft 7 are adjusted up and down, the rotating roller 23 can rotate synchronously in opposite directions.

[0046] like Figure 2 and Figure 8 As shown, in some embodiments, the mounting frame 6 is provided with a wind hood 25. The wind hood 25 has an arc-shaped structure and is coaxially arranged with the transfer cylinder 8. The air outlet of the exhaust fan 1205 is connected to the wind hood 25 by a guide pipe 26. Preferably, there is a gap between the flared opening of the wind hood 25 and the outer surface of the transfer cylinder 8, which allows the label to pass through. Through the wind hood 25, the airflow drawn from the air chamber by the exhaust fan 1205 is guided into the wind hood 25 through the guide pipe 26, and then blows the transfer cylinder 8 through the wind hood 25. When the label is adsorbed onto the surface of the transfer cylinder 8 under negative pressure, the airflow in the wind hood 25 will blow the label. Under the action of the wind, the label is more tightly attached to the transfer cylinder 8, which is more conducive to the subsequent transfer and attachment of the label to the surface of the item, thereby improving practicality.

[0047] like Figure 4As shown, in some embodiments, a heating cylinder 27 is connected to the feed tube 26 and is mounted on the mounting plate 3. An electric heating wire 28 is installed inside the heating cylinder 27. Through the heating cylinder 27 and the electric heating wire 28, the airflow first flows into the heating cylinder 27. After the electric heating wire 28 is energized, it heats the airflow. The heated airflow then blows the label adsorbed on the transfer cylinder 8. Under the blowing of hot air, the adhesiveness of the label is improved, making the label more tightly and firmly attached to the surface of the item, thereby improving the label application effect.

[0048] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
