Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, and in particular to an optimized label peeling structure and a right-angle sealing machine using the same. 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 of precision components such as solid-state drives need to be sealed with right-angle labels so that the labels fit the right-angle joint between the top and side surfaces of the packaging box, forming an anti-tamper mark to prevent the products from being opened without authorization during warehousing, transportation and sales.

[0004] Currently, the label peeling mechanism in right-angle sealing machines in the industry typically utilizes components such as folding plates. These components usually have a flat surface, which the conveyor belt adheres to during transport. As it passes through the folding plate's corner, the label belt undergoes a bend, causing the label on the belt to partially detach from the backing paper and stand upright due to its rigidity and the release liner's properties. However, due to tension fluctuations in the conveyor belt, variations in label material, and the large angle bend of the backing paper at the folding plate's corner, the conveyor belt often fails to adhere to the flat surface of the folding plate, instead forming an angle with the corner. This means the conveyor belt is tilted rather than ideally perpendicular. Consequently, the label at the corner of the folding plate tends to tilt with the conveyor belt's posture, resulting in the peeled portion of the label not contacting the incoming product in a relatively parallel manner. This leads to misalignment during label-product bonding, increasing the defect rate, raising manual inspection and rework costs, and impacting overall production efficiency.

[0005] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an optimized label peeling structure, comprising a folding plate and a backing plate, wherein the folding plate has a bonding plane for the feeding tape to adhere, and one end of the folding plate forms a bent portion; One end of the abutment plate abuts against the bonding surface to press the material strip tightly onto the bonding surface.

[0008] As a further embodiment of this invention: the abutment plate is made of an elastic material. One end of the abutment plate is fixedly installed, and the other end elastically abuts against the surface of the material strip.

[0009] As a further embodiment of this utility model: one end of the abutment plate is fixed to a fixing post, and the other end forms an abutment end. The abutment plate is curved, so that the abutment end generates abutment force through its own elastic deformation to press the material strip tightly onto the bonding surface.

[0010] As a further embodiment of this utility model: the abutting end abuts against the fitting plane near the bending part.

[0011] As a further embodiment of this utility model: a fixing plate is fixedly connected to the side of the folding plate opposite to the bonding plane, a strip groove is provided on the bonding plane, a screw hole is provided on the fixing plate, and a bolt is provided on the outside of the folding plate. The bolt can pass through the strip groove and be screwed into the screw hole.

[0012] As a further embodiment of this utility model: it also includes an operating table, on which a label conveying port is provided, the bent part extends upward and is located at the lower end of the label conveying port, when the material belt passes through the bent part, the part of the label that is detached is vertical and protrudes through the label conveying port; The operating table is also equipped with a labeling plate corresponding to the label conveying port. The labeling plate is located at the rear end of the folding plate in the direction of product travel when labeling. The rear end of the labeling plate is connected to an elastic reset mechanism so that the labeling plate can reset itself after the product leaves.

[0013] As a further embodiment of this utility model: a label pressure roller corresponding to the label conveying port is provided at the lower end of the operating table, 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: a movable positioning plate is also provided on the operating table to provide guidance for the translation of the product; The movable positioning plate includes a backing surface and a fixing surface. The backing surface and the fixing surface form a right angle plate. A strip groove is provided on the fixing surface. A screw hole is provided on the operating table. A bolt is provided on the fixing surface. The bolt can pass through the strip groove and be screwed into the screw hole.

[0015] As a further embodiment of this utility model: the elastic reset mechanism includes a fixed block disposed on 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 an elastic element sleeved on the outside of the guide rod disposed between the labeling plate and the fixed block. The operating platform is equipped with a stop protection block located between the labeling plate and the fixing block.

[0016] This utility model also proposes a right-angle sealing machine, which includes the aforementioned optimized label peeling structure.

[0017] Compared with the prior art, the beneficial effects of this technical solution are as follows: When the label tape is conveyed, it is located on one side of the bonding plane of the folding plate and is bonded. At the same time as the tape is conveyed, one end of the abutment plate abuts against the bonding plane, and the tape passes between the two, thereby clamping the tape between the abutment plate and the bonding plane. Then the tape is conveyed to the bending part, and the backing paper of the tape is forcibly turned with the bending part. Due to its own rigidity and the influence of the backing paper material (such as the backing paper being release paper), the label pasted on the backing paper separates from the backing paper and gradually peels off a portion. Then the tape stops conveying. At this time, since the abutment plate continues to press the unpeeled part of the tape on the bonding plane, it can restrain the posture of the peeled part of the label, prevent the label from tilting or falling due to the pulling effect of the backing paper turning, and ensure that the label maintains the preset upright state for bonding, laying the foundation for subsequent accurate bonding with the product. The fixed column provides a stable support base for the abutment plate. One end of the abutment plate is fixed to it to ensure the overall position of the abutment plate is fixed and to prevent it from shifting. Then, the abutment plate is bent so that the abutting end abuts against the material strip on the mating plane. The abutment plate in the bent state has elastic potential energy, which can continuously provide a pressing force on the material strip. Due to its elastic characteristics, it can not hinder the feeding of the material strip, but can continuously constrain the material strip and the label.

[0021] 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.

[0022] Please see Figure 1-7 A label peeling optimization structure includes a folding plate 1 and a backing plate 2. The folding plate 1 has a bonding plane 11 for the feeding tape to be bonded, and one end of the folding plate 1 forms a bent portion 12. One end of the abutment plate 2 abuts against the bonding surface 11 to press the strip tightly onto the strip bonding surface 11.

[0023] Specifically, during the conveying process, the label tape is positioned on one side of the bonding plane 11 of the folding plate 1 and is bonded together. While the tape is being conveyed, one end of the abutment plate 2 abuts against the bonding plane, and the tape passes between the two, thus clamping the tape between the abutment plate 2 and the bonding plane 11. Then, the tape is conveyed to the bending section 12, where the backing paper of the tape is forcibly turned. Due to its own rigidity and the material of the backing paper (such as release paper), the label attached to the backing paper separates from the backing paper and is gradually peeled off. Subsequently, the tape is stopped from being conveyed. At this time, because the abutment plate 2 continues to press the unpeeled portion of the tape on the bonding plane 11, it can restrain the posture of the peeled portion of the label, preventing the label from tilting or falling due to the pulling effect of the turning of the backing paper, ensuring that the label remains in the preset upright state for application, laying the foundation for accurate application to the product.

[0024] Based on the above embodiments, it is further proposed that the abutment plate 2 be made of an elastic material. One end of the abutment plate 2 is fixedly installed, and the other end is elastically abutted against the material strip contact surface 11.

[0025] Specifically, the abutment plate 2 is made of an elastic material, such as silicone, and one end of it is fixed by a fixed structure to form a stable support; the other end naturally abuts against the bonding surface 11, and it generates a continuous abutting force through its own elastic deformation to tightly press the material strip against the bonding surface 11.

[0026] Based on the above embodiments, it is further proposed that one end of the abutment plate 2 is fixed to the fixing post 21, and the other end forms an abutment end 22. The abutment plate 2 is curved, so that the abutment end 22 generates abutment force through its own elastic deformation to press the material strip onto the bonding plane 11.

[0027] Specifically, the fixed column 21 provides a stable support base for the abutment plate 2. One end of the abutment plate 2 is fixed to it, which can ensure the overall position of the abutment plate 2 is fixed and prevent it from shifting. Then, the abutment plate 2 is bent so that the abutting end 22 of the abutment plate 2 abuts against the material strip on the mating plane 11. The abutment plate in the bent state has elastic potential energy, which can continuously provide pressure on the material strip. Due to its elastic characteristics, it can not hinder the feeding of the material strip, but can continuously constrain the material strip and the label.

[0028] Furthermore, the abutting end 22 abuts against the bonding surface 11 near the bend 12. When a label is partially peeled off from the backing paper, the unpeeled portion is located at the upper end of the bonding surface 11. Therefore, by setting the abutting position of the abutting end 22 at the upper end of the bonding surface 11 near the bend 12, it can be ensured that the abutting end 22 always presses against the label that needs to be peeled off and bonded to the product at that moment.

[0029] Based on the above embodiments, it is further proposed that a fixing plate 13 is fixedly connected to the side of the folding plate 1 that is opposite to the bonding plane 11, a strip groove 14 is opened on the bonding plane 11, a screw hole 15 is opened on the fixing plate 13, and a bolt 3 is provided on the outside of the folding plate 1. The bolt 3 can pass through the strip groove 14 and be screwed into the screw hole 15.

[0030] Specifically, when dealing with labels of different sizes, the fixing relationship between the folding plate 1 and the fixing plate 13 can be released by loosening bolt 3. At this time, the folding plate 1 can be adjusted up and down through the strip groove 14. After adjusting to the preset position, tighten bolt 3 again. The head of bolt 3 clamps the folding plate 1 between bolt 3 and fixing plate 13 by pressing the edge of the strip groove 14, thereby fixing the position of the folding plate 1 to accommodate label tapes of different sizes.

[0031] Based on the above embodiments, it is further proposed that the operating table 4 is also included, the operating table 4 is provided with a label conveying port 41, the bending part 12 extends upward and is located at the lower end of the label conveying port 41, when the material belt passes through the bending part 12, the part of the label that is detached is vertical and protrudes through the label conveying port 41. The operating table 4 is also equipped with a labeling plate 5 corresponding to the label conveying port 41. The labeling plate 5 is located at the rear end of the folding plate 1 in the direction of product labeling. The rear end of the labeling plate 5 is connected to an elastic reset mechanism 6 so that the labeling plate 5 can reset itself after the product leaves.

[0032] Specifically, the product is placed on the operating table 4, with one right angle of the product aligned with the labeling plate 5 and moved horizontally. This allows the right angle side of the product to adhere to the peeled label standing vertically on the label conveyor 41. Under the action of the product and the labeling plate 5, the label adheres tightly to the product. Then, as the product continues to move forward, the part of the label that has not yet detached is pulled off from the backing paper of the conveyor belt and adhered to the bottom surface of the product, thus completing the right angle label application. The product is then removed, and the labeling plate 5 is reset by the elastic reset mechanism 6 to prepare for the next label application.

[0033] Based on the above embodiments, it is further proposed that the lower end of the operating table 4 is provided with a label pressure roller 42 corresponding to the label conveying port 41. The upper end of the label pressure roller 42 is flush with the lower end of the labeling plate 5, and the label pressure roller 42 is located behind the retraction path of the labeling plate 5.

[0034] Specifically, during the process of the product pushing the labeling plate 5 to move horizontally, the part that is detached from the label position is simultaneously detached from the backing paper. Subsequently, the second part is pressed by the bottom surface of the labeling plate 5 and the label pressure roller 42, so that it is tightly attached to the bottom surface of the product to ensure the firmness of the label attachment.

[0035] Based on the above embodiments, it is further proposed that the operating table 4 is also provided with a movable positioning plate 7, which is used to provide guidance for the translation of the product.

[0036] Specifically, when the product is moved, the moving positioning plate 7 is used to guide the product's movement, thereby limiting the product's left or right deviation or tilt during the movement and ensuring that the product always moves along the preset trajectory. This ensures that the right angle of the product accurately aligns with the label at the label conveying port 41, improving the accuracy and consistency of labeling.

[0037] Preferably, the movable positioning plate 7 includes a backing surface 71 and a fixing surface 72. The backing surface 71 and the fixing surface 72 form a right angle plate. A strip groove 73 is provided on the fixing surface 72. A screw hole 43 is provided on the operating table 4. A bolt 8 is provided on the fixing surface 72. The bolt 8 can pass through the strip groove 73 and be screwed into the screw hole 43 for fixation.

[0038] Specifically, the function of the backing surface 71 is to provide a support surface for the product during translation. When the product is pushed, it can always be in contact with the backing surface, thus ensuring that the product always translates along the preset trajectory. Through the setting of the second groove 73 on the fixed surface 72, the position of the backing surface 71 can be adjusted by loosening the second bolt 8 and then tightening the second bolt 8 to fix it in the screw hole 43. This can press the fixed surface 72 against the operating table 4, thereby fixing the position of the backing surface 71 and making the position of the backing surface 71 adjustable, thus adapting to the labeling needs of products of different sizes.

[0039] Based on the above embodiments, the elastic reset mechanism 6 is further proposed to include a fixed block 61 disposed on the upper end of the operating table 4, a sliding sleeve 62 disposed on the fixed block 61, a guide rod 51 slidably engaged with the sliding sleeve 62 disposed on the labeling plate 5, the guide rod 51 passing through the sliding sleeve 62 and connected to a limit block 63, and an elastic element 64 sleeved on the outside of the guide rod 51 disposed between the labeling plate 5 and the fixed block 61.

[0040] Specifically, the fixing block 61 provides fixed support. When the labeling plate 5 is pushed by the product, the labeling plate 5 drives the guide rod 51 to slide along the axis of the sliding sleeve 62. At this time, the second elastic element 64 between the labeling plate 5 and the fixing block 61 is compressed, generating a rebound force. When the product finishes labeling and removes the contact force on the labeling plate 5, the second elastic element 64 releases the rebound force, pushing the labeling plate 5 to reset and move. This ensures that the labeling plate 5 remains straight when it moves horizontally. Automatic reset is achieved with the help of the second elastic element 64. The limiting block 63 moves synchronously with the guide rod 51. Its size is larger than the hole diameter of the sliding sleeve 62, which can prevent the guide rod 51 from coming out of the sliding sleeve 62.

[0041] Furthermore, the operating table 4 is provided with a stop protection block 9 located between the labeling plate 5 and the fixing block 61. When the product is pushed to move the labeling plate 5, the stop protection block 9 can limit the maximum range of translation of the labeling plate 5, so as to avoid the labeling plate 5 from excessively compressing the elastic element 64 and causing damage to the elastic element 64, wherein the elastic element 64 is a spring.

[0042] Based on the above-mentioned optimized label peeling structure, this utility model also provides a right-angle sealing machine, the blowing device including the optimized label peeling structure of any of the above-mentioned items.

[0043] like Figure 7 As shown, the label peeling optimization structure is installed on the right-angle sealing machine. Under the driving force of the conveying mechanism (such as traction roller and feeding roller), the material belt is fed and wrapped around the folding plate 1 to complete the peeling of the label.

[0044] 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.
