Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, and in particular to a dual-station high-efficiency right-angle sealing labeling machine. Background Technology

[0002] Right-angle sealing and labeling machines can affix labels at the corners of the top and side surfaces of packaging boxes, achieving a right-angle seal. This technology is widely used in many industries, playing a crucial role, especially in scenarios where product safety and integrity are paramount.

[0003] In the field of electronic product packaging, the packaging boxes for precision components such as solid-state drives need to achieve a dual function through right-angle sealing and labeling: firstly, by affixing the label to the right-angle seam between the top and side surfaces of the packaging box, a tamper-evident mark is formed, preventing the product from being opened without authorization during warehousing, transportation, and sales; secondly, the label carries key information such as product model, capacity, production batch, and anti-counterfeiting code, meeting the needs of traceability and consumer identification. Therefore, the accuracy, efficiency, and ease of operation of right-angle sealing and labeling directly affect the product packaging quality and production cycle.

[0004] As described in the current patent CN219635706U, a right-angle labeling machine includes a machine body with a product placement platform and a label conveying port. A material feeding assembly, a material discharging assembly, and multiple auxiliary rollers are sequentially arranged on one side of the machine body. The material feeding assembly feeds the label material to the label conveying port via the multiple auxiliary rollers, and the label is then discharged by the material discharging assembly. A label peeling block is also provided at the label conveying port of the product placement platform, which peels the label from the label material vertically and partially along the label conveying port. The product placement platform also has a labeling plate located on one side of the label conveying port and a transfer assembly connected to the labeling plate.

[0005] In the aforementioned patents, the right-angle sealing and labeling machines are all designed with a single workstation. The workflow of this type of equipment is as follows: the operator positions the packaging box to be labeled at the labeling position on the single-station operating table, starts the equipment, and operates it to complete the labeling at one right angle on one end of the packaging box; subsequently, the operator needs to manually remove the packaging box from the operating table, flip it over, reposition it in the original labeling position, and repeat the operation to complete the sealing and labeling at the other right angle.

[0006] Since only one end of the packaging box can be labeled at a time, it requires operators to manually flip and reposition the product, which adds extra time for picking up, flipping, and recalibrating. It cannot balance production efficiency, labeling accuracy and ease of operation, and is difficult to meet the needs of large-scale, high-precision packaging for electronic products such as solid-state drives.

[0007] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0008] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a dual-station high-efficiency right-angle sealing and labeling machine, including an equipment box, an operating table on the equipment box, label conveying ports on both sides of the upper end of the operating table, labeling plates opposite each other on the operating table, and elastic reset mechanisms connected to the opposite sides of the two labeling plates, so that the two labeling plates can be relatively translated along the surface of the operating table. The equipment box is equipped with two feeding rollers, two sets of label peeling components, and two sets of material conveying components on one side. The material conveying assembly includes two fixed plates, with a traction roller and a clamping roller disposed between the two fixed plates. The equipment box is equipped with a drive source for driving the traction roller to rotate, and the clamping roller can clamp the material belt between itself and the traction roller. The material belt is conveyed by rotating the traction roller. The material strip is drawn out from the feeding roller and first undergoes label peeling by the label peeling assembly. The partially peeled labels stand upright at the label conveying port and then pass through the traction roller and clamping roller.

[0010] As a further embodiment of this utility model: the label peeling assembly includes a folding plate extending into the label conveying port. After the material belt is bent around the folding plate, the label is partially peeled off and stands upright in the label conveying port, with the label higher than the surface of the operating table, and then passes through the material belt conveying assembly.

[0011] As a further embodiment of this utility model: a U-shaped support structure is also provided between the two fixed plates, the two ends of the clamping roller are rotatably connected to the support, and a rotating shaft connected to the two fixed plates is provided at the lower end of the support; Rotating the support can disengage the clamping roller from the traction roller, and rotating the support again can cause the clamping roller to be inclined and abut against the traction roller.

[0012] As a further embodiment of this utility model: the bracket is provided with a base plate and a movable frame, the upper sides of the movable frame are located between the clamping roller side and the bracket, and a first elastic element is provided between the movable frame and the base plate; The support has movable slots on both sides, and the clamping roller has two rotating shafts at both ends, which pass through the movable frame and the movable slots.

[0013] As a further embodiment of this utility model: a label pressure roller is provided on the operating table, located inside the label conveying port. The upper end of the label pressure roller is flush with the lower end of the labeling plate, and the label pressure roller is located behind the retraction path of the labeling plate.

[0014] As a further embodiment of this utility model: the elastic reset mechanism includes fixed blocks disposed on both sides of the upper end of the operating table, a sliding sleeve disposed on the fixed block, a guide rod slidably engaged with the sliding sleeve disposed on the labeling plate, the guide rod passing through the sliding sleeve and connected to a limit block, and a second elastic element sleeved on the outside of the guide rod disposed between the labeling plate and the fixed block.

[0015] As a further embodiment of this utility model: a fixing column is also provided on one side of the equipment box, and a soft rubber plate is provided on the fixing column. One end of the soft rubber plate is fixedly connected to the fixing column, and the other end is located between the folding plate and the label pressure roller, and is in a bent state, so that the end of the soft rubber plate abuts against the folding plate.

[0016] As a further embodiment of this utility model: a guide roller is also provided on one side of the equipment box, located between the feeding roller and the label peeling assembly; A guide roller 2 is also provided between the two fixed plates, located at the upper end of the traction roller.

[0017] As a further embodiment of this utility model, a movable positioning plate is also provided on the operating table.

[0018] As a further embodiment of this utility model: a base platform is provided at the lower end of the equipment box, a base frame is provided at the lower end of the base platform, a collection frame is placed on the base frame, and a discharge port corresponding to the collection frame is opened on the base platform.

[0019] Compared with existing technologies, the beneficial effects of this technical solution are as follows: When sealing the product at right angles, the product is placed on the operating table, and the right angle of one side of the product is aligned with the labeling plate on the other side and moved horizontally. This allows the side of the product to adhere to the vertical part of the label, and the labeling plate helps to press it firmly against the product. As the product pushes the labeling plate, the part of the label that has not yet detached from the material belt is pulled away by the product and attached to the bottom surface of the product, thus attaching the label to the right angle of the product. At this point, one side of the product is sealed at right angles. Then, the product is pulled back and moved horizontally to the labeling plate on the opposite side, allowing the other side of the product to push the corresponding labeling plate and complete the right angle sealing on the other side. Subsequently, the product is removed from the operating table, and the two labeling plates are reset by the elastic reset mechanism. At the same time, the drive source drives the traction roller to move the material belt, allowing the material belt to be pulled out a specified distance, ensuring a continuous supply of labels. This achieves efficient and continuous sealing and labeling of the product at right angles on both sides, reduces manual flipping operations, and improves labeling efficiency and stability.

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-7 A dual-station high-efficiency right-angle sealing and labeling machine includes an equipment box 1, an operating table 2 on the equipment box 1, label conveying ports 21 on both sides of the upper end of the operating table 2, labeling plates 3 opposite to each other on the operating table 2, and elastic reset mechanisms 31 connected to the opposite sides of the two labeling plates 3, so that the two labeling plates 3 can be relatively translated along the surface of the operating table 2. Two feeding rollers 4, two sets of label peeling assemblies 5, and two sets of material conveying assemblies 6 are provided on one side of the equipment box 1. The material conveying assembly 6 includes two fixed plates 61, and a traction roller 62 and a clamping roller 63 are arranged between the two fixed plates 61. A drive source 64 for driving the traction roller 62 to rotate is installed on the equipment box 1, and the clamping roller 63 can clamp the material belt between itself and the traction roller 62. The material belt is conveyed by the rotation of the traction roller 62. The material belt is led out from the feeding roller 4 and first passes through the label peeling assembly 5 for label peeling. The partially peeled label stands vertically at the label conveying port 21, and then passes through the traction roller 62 and the clamping roller 63.

[0025] Specifically, the material strip is first wound: a material cylinder is installed on two feeding rollers 4, and a material strip with a label is drawn from the material cylinder. After the material strip passes through the label peeling component 5, the strip with the label peeled off first passes through the traction roller 62, and then the material strip passes between the traction roller 62 and the clamping roller 63. At this time, the traction roller 62 is driven by the drive source 64, and the material strip is clamped by the traction roller 62 and the clamping roller 63, so that the material strip can be continuously drawn out. Through the cooperation of the encoder and photoelectric sensor, the photoelectric sensor is set at the corresponding label conveying port 21. When the product is pushed to the... When the labeling plate 3 moves to place the label at the right angle of the product, the photoelectric sensor is triggered and transmits the signal to the drive source 64. At this time, the drive source 64 drives the traction roller 62 to rotate as specified, thereby driving the material belt to be pulled out in a preset manner. The material belt can be pulled out at a distance that is just enough for each label to stand at the label conveyor 21, thereby achieving the effect of automatic material belt conveying. The encoder, the program of the photoelectric sensor, and the cooperation with the drive source 64 are all mature technical means well known to those skilled in the art, and those skilled in the art can easily understand them, so they will not be described in detail here. When sealing the product at a right angle, the product is placed on the operating table 2, and the right angle of one side of the product is aligned with the labeling plate 3 on the other side and moved horizontally. This allows the side of the product to adhere to the vertical part of the label, and the labeling plate 3 helps to press it firmly against the product. As the product pushes the labeling plate 3, the part of the label that has not yet detached from the material belt is pulled away by the product and attached to the bottom surface of the product, thus attaching the label to the right angle of the product. At this point, one side of the product is sealed at a right angle. Then, the product is pulled back and moved horizontally to the labeling plate 3 on the opposite side, allowing the other side of the product to push the corresponding labeling plate 3 and complete the right angle sealing on the other side. The product is then removed from the operating table 2, and the two labeling plates 3 are reset by the elastic reset mechanism 31. At the same time, the drive source 64 drives the traction roller 62 to move the material belt, allowing the material belt to be pulled out a specified distance to ensure a continuous supply of labels. This achieves efficient and continuous sealing and labeling of the product at both right angles, reducing manual flipping operations and improving labeling efficiency and stability.

[0026] Based on the above embodiments, the label peeling assembly 5 is further proposed to include a folding plate 51 and a corner plate 52 extending into the label conveying port 21. The folding plate 51 is fixedly installed on the side of the corner plate 52 facing the labeling plate 3. After the material strip is bent around the folding plate 51, the label is partially peeled off and stands upright in the label conveying port 21, with the label higher than the surface of the operating table 2, and then passes through the material strip conveying assembly 6.

[0027] Specifically, the corner plate 52 is fixed to the equipment box 1, and then the folding plate 51 is fixedly installed on one side of the corner plate 52. The upper end of the folding plate 51 extends into the label conveying port 21, forming a preset peeling station. When the material belt is pulled out from the feeding roller 4 under the traction of the material belt conveying assembly 6 and passes around the folding plate 51 before being introduced into the material belt conveying assembly 6, the material belt undergoes a sharp turn when passing around the folding plate 51. As a result, the label on the material belt cannot bend synchronously with the material belt due to its own rigidity and the difference in adhesion with the backing paper (such as the backing paper being release paper). This causes the backing paper to continue to be pulled by the material belt conveying assembly 6, and the label... Separated from the backing paper, the label stands vertically inside the label conveyor 21 under the guidance of the folding plate 51, with the top of the label higher than the surface of the operating table 2. The part above the operating table 2 is in a state of waiting to be applied. When the product is pushed toward the labeling plate 3, the peeled part of the label is attached to the side of the product. As the product continues to move horizontally, the remaining part of the label is detached from the backing paper and attached to the bottom surface of the product. The above structure realizes automatic label peeling, which is convenient for subsequent bonding with the product. The overall structure is simple and efficient, improves the consistency of label peeling and labeling accuracy, and helps to improve the overall labeling efficiency.

[0028] Based on the above embodiments, it is further proposed that the operating table 2 is provided with a label pressure roller 22 located in the label conveying port 21. The upper end of the label pressure roller 22 is flush with the lower end of the labeling plate 3, and the label pressure roller 22 is located behind the retraction path of the labeling plate 3.

[0029] Specifically, during the process of the product pushing the labeling plate 3 to move horizontally, the part of the label that has not been completely peeled off will be completely separated from the backing paper. The horizontal movement of the labeling plate 3 will pass through the label pressure roller 22. With the upper and lower ends of the two being flush, the label pressure roller 22 can roll the part of the label that is attached to the product, so that the remaining part of the label is tightly attached to the bottom surface of the product.

[0030] Preferably, the operating table 2 is also equipped with a movable positioning plate 23; when the product is moved in both directions, it fits against the side of the movable positioning plate 23 along its length, thereby providing guidance for the product's movement. When the operator pushes the product to move on the operating table 2 to complete the double-sided labeling, the movable positioning plate 23 can limit the product's left or right deviation or tilt during the movement, ensuring that the product always moves along the preset trajectory, so that the right angles at both ends of the product are precisely aligned with the label positions in the label conveying ports 21 on both sides, ensuring the accuracy and consistency of the double-sided labeling.

[0031] Based on the above embodiments, the elastic reset mechanism 31 is further proposed to include a fixing block 311 disposed on both sides of the upper end of the operating table 2, a sliding sleeve 312 disposed on the fixing block 311, a guide rod 313 slidably engaged with the sliding sleeve 312 disposed on the labeling plate 3, the guide rod 313 passes through the sliding sleeve 312 and is connected to a limit block 314, and a second elastic element 315 sleeved on the outside of the guide rod 313 is disposed between the labeling plate 3 and the fixing block 311.

[0032] Specifically, the fixing block 311 provides fixed support. When the labeling plate 3 is pushed by the product, the labeling plate 3 drives the guide rod 313 to slide along the axis of the sliding sleeve 312. At this time, the second elastic element 315 between the labeling plate 3 and the fixing block 311 is compressed, generating a rebound force. The limiting block 314 moves synchronously with the guide rod 313. Its size is larger than the hole diameter of the sliding sleeve 312, which can prevent the guide rod 313 from coming out of the sliding sleeve 312. When the product is labeled and the contact force on the labeling plate 3 is removed, the second elastic element 315 releases the rebound force and pushes the labeling plate 3 to reset and move. This can ensure that the labeling plate 3 remains straight when it moves horizontally, and automatic reset is achieved with the help of the second elastic element 315.

[0033] Based on the above embodiments, it is further proposed that a fixing column 8 is also provided on one side of the equipment box 1, and a soft rubber plate 81 is provided on the fixing column 8. One end of the soft rubber plate 81 is fixedly connected to the fixing column 8, and the other end is located between the folding plate 51 and the label pressure roller 22, and is in a bent state, so that the end of the soft rubber plate 81 abuts against the folding plate 51.

[0034] Specifically, a fixed column 8 is set on the equipment box 1 to provide a stable mounting base for the flexible rubber plate 81. When the material belt passes around the folding plate 51 during the conveying process, the bending elasticity of the flexible rubber plate 81 keeps it in contact with and presses the material belt, ensuring that the material belt and the surface of the folding plate 51 remain in contact. When the material belt bends around the folding plate 51 and the label begins to detach, the continuous pressing force of the flexible rubber plate 81 can restrain the posture of the label, keeping the label in contact with the surface of the folding plate 51. This keeps the label and its detached parts in a vertical position, preventing the label from tilting as the material belt bends, which would cause the product to not be accurately attached to the label when it moves towards the product, thus ensuring the effective adhesion of the label to the product.

[0035] Based on the above embodiments, it is further proposed that a U-shaped support 7 is provided between the two fixed plates 61, the two ends of the clamping roller 63 are rotatably connected to the support 7, and the lower end of the support 7 is provided with a rotating shaft 71 connected to the two fixed plates 61. Rotating the bracket 7 can disengage the clamping roller 63 from the traction roller 62, and rotating the bracket 7 again can cause the clamping roller 63 to abut against the traction roller 62 in an inclined state.

[0036] Specifically, the U-shaped bracket 7 is rotatably mounted to the two fixed plates 61 via a pivot 71, as shown below. Figure 5 and Figure 6 As shown, a handle is provided at the lower end of the bracket 7. The operator can rotate the bracket 7 by rotating the handle, which drives the clamping roller 63, causing the clamping roller 63 to open outward from the two fixed plates 61. Figure 6 In the state shown, the space between the clamping roller 63 and the traction roller 62 is opened to allow the material strip to pass through between the clamping roller 63 and the traction roller 62. After the material strip passes through, the bracket 7 rotates again, causing the clamping roller 63 to press against the traction roller 62 and clamp the material strip. Finally, the bracket 7 and the clamping roller 63 are slightly tilted towards the inside of the two fixed plates 61, and the traction roller 62 holds the clamping roller 63 against itself, which can prevent the bracket 7 and the clamping roller 63 from rotating on their own.

[0037] Based on the above embodiments, it is further proposed that the bracket 7 is provided with a base plate 72 and a movable frame 73. The upper sides of the movable frame 73 are located between the side ends of the clamping roller 63 and the bracket 7. A first elastic element 74 is provided between the movable frame 73 and the base plate 72. The support frame 7 has movable slots 75 on both sides, and the clamping roller 63 has a rotating shaft 65 at both ends, which passes through the movable frame 73 and the movable slots 75.

[0038] Specifically, during the process of rotating the bracket 7 to bring the clamping roller 63 into contact with the traction roller 62, the clamping roller 63 squeezes against the traction roller 62 as it rotates, causing the clamping roller 63 to move downwards after being squeezed, and pushing the movable frame 73 to compress the first elastic element 74 between it and the base plate 72. As it rotates continuously, it is fixed in an inclined state towards the inside of the two fixed plates 61. The traction roller 62 holds the clamping roller 63 in place, preventing it from rotating outwards on its own. At this time, the rebound force of the first elastic element 74 is used to make the clamping roller 63 always apply a pushing force to the traction roller 62, thereby continuously clamping the material belt between the two, ensuring that the traction roller 62 is currently conveying the material belt.

[0039] In the technical solution of the utility model, both the traction roller 62 and the clamping roller 63 are rubber rollers. The rubber rollers have a certain degree of deformation. The pressure generated by the contact will cause the contact surface of the rubber roller to undergo adaptive deformation, increasing the contact area with the material belt, thereby increasing the friction force and effectively preventing slippage and misalignment during the material belt conveying process, ensuring the stability and accuracy of the material belt feeding.

[0040] Based on the above embodiments, it is further proposed that a guide roller 11 is also provided on one side of the equipment box 1, located between the feeding roller 4 and the label peeling component 5; a guide roller 2 66 is also provided between the two fixed plates 61, located at the upper end of the traction roller 62. The function of the guide roller 11 is that after the material belt is led out from the feeding roller 4, it can first pass through the guide roller 11 for transition, then go around the folding plate 51, and then the material belt passes through the guide roller 2 66 between the traction roller 62 and the clamping roller 63. By using the guide roller 11 and the guide roller 2 66, the material belt can be accurately guided and the stability of the material belt during the conveying process can be optimized to maintain the continuous tension of the material belt.

[0041] Preferably, the equipment box 1 has a base platform 9 at its lower end, and a base frame 91 is provided at the lower end of the base platform 9. A collection frame 92 is placed on the base frame 91, and a discharge port 93 corresponding to the collection frame 92 is opened on the base platform 9. After the stripped label material passes through the traction roller 62 and the clamping roller 63, it enters the collection frame 92 on the guide base frame 91 through the discharge port 93 for recycling.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
