Description

Technical Field

[0001] This utility model relates to the field of shoe material processing, and in particular to an automatic shoe box labeling machine. Background Technology

[0002] In the packaging process of footwear products, shoebox labeling is one of the key steps, directly affecting the product's appearance and brand image. Traditional labeling methods rely heavily on manual operation, resulting in low efficiency, large label placement deviations, and high labor costs. With the development of automation technology, automatic labeling machines have gradually been introduced into production lines, but the following technical pain points still exist in practical applications: 1. Insufficient label peeling accuracy: When existing equipment peels labels mechanically or pneumatically, uneven tape tension easily leads to label misalignment or damage, especially with thin or special materials. 2. Poor label peeling effect: The peeling mechanism has low adaptability to label size, easily causing labels to curl or tear during peeling, especially with insufficient compatibility with ultra-thin labels. 3. Insufficient labeling accuracy: Relying on mechanical limits or simple sensor positioning makes it difficult to achieve accurate application on complex paths, leading to label misalignment or tilting.

[0003] While existing technologies have proposed some improvements to address the aforementioned problems (such as adjusting the material belt tension by adding tension rollers and optimizing the vacuum nozzle layout), they still suffer from drawbacks such as complex structure, limited adjustment range, and high maintenance costs. Therefore, there is an urgent need for a highly efficient, stable, and adaptable automatic shoe box labeling device to overcome the shortcomings of existing technologies. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an automatic shoe box labeling machine.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses an automatic shoe box labeling machine, comprising a label release component, a material tape recycling component, a label peeling component, a label attaching component, and a conveying component:

[0007] The label release assembly includes a material belt mounting wheel, a traction wheel, a servo motor-driven feeding belt, and a feeding speed adjustment wheel system consisting of a feeding friction wheel and a feeding spring clamping wheel;

[0008] The material strip recovery assembly includes a take-up wheel and a take-up speed adjustment wheel system consisting of a take-up friction wheel and a take-up spring clamping wheel, wherein the take-up friction wheel is connected to a servo motor drive.

[0009] The label peeling assembly includes a tearing cylinder, a paper pushing roller, a label feeding plate, a label pressing plate, a label pressing block, a label dragging plate, a photoelectric sensor, and a pressing cylinder. The tearing cylinder drives the paper pushing roller to peel off the label, the label pressing block cooperates with the label dragging plate to position the label, and the photoelectric sensor triggers the tearing action.

[0010] The label attaching component includes a label suction cylinder, a vacuum nozzle, an XY moving module, and a blocking cylinder. After the vacuum nozzle suctions the label, it is attached to the shoe box through the XY moving module. The blocking cylinder controls the stopping position of the shoe box on the transmission component.

[0011] The transmission components include a horizontal conveyor belt and a drive motor that is linked to the servo motor.

[0012] As a preferred embodiment of this utility model, the surface of the feeding friction wheel of the feeding speed regulating wheel system is covered with a silicone layer, and the clamping force of the feeding spring clamping wheel is adjustable in the range of 5-20N.

[0013] As a preferred technical solution of this utility model, the photoelectric sensor is an infrared reflective sensor or a through-beam sensor, whose detection signal triggers the adsorption action of the label-adsorbing cylinder, and forms a closed-loop control with the movement path of the XY moving module.

[0014] As a preferred technical solution of this utility model, the vacuum nozzles are arranged in a concentric circle or rectangular array, each vacuum nozzle is connected to a negative pressure source through an independent air path, and the suction force can be adjusted individually.

[0015] As a preferred technical solution of this utility model, the label feeding plate and the label pressing block are arranged in parallel and form a label channel between them. The width of the label channel is continuously adjusted by an elongated hole provided on the fixed label dragging plate, with an adjustment range of 10-30mm. The label pressing block is driven to move up and down by a downward pressing cylinder and is arranged in parallel with the label dragging plate.

[0016] As a preferred technical solution of this utility model, a roller for receiving and guiding is fixed on the inner side of the label feeding plate, and the surface of the roller is coated with polytetrafluoroethylene to reduce the frictional resistance of the label.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. The feeding / receiving speed adjustment wheel system (first, the receiving friction wheel and the spring pressure wheel) is coordinated with the servo motor control to ensure dynamic balance of the material belt tension. Combined with the precise peeling action of the label tearing cylinder and the paper pushing wheel, it is especially suitable for ultra-thin or fragile labels.

[0019] 2. The photoelectric sensor and the XY movement module form a closed-loop control, which, combined with the intermittent positioning of the blocking cylinder, controls the labeling position error within +0.5mm;

[0020] 3. The servo motor links the feeding, receiving, and conveying components, and the friction wheel clamping force can be adjusted (5-20N adjustable range) to eliminate the risk of material belt accumulation or breakage; the modular design (such as detachable label plate and quick-change vacuum nozzle) simplifies the cleaning and component replacement process.

Detailed Implementation

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] In the attached diagram, all identical reference numerals refer to the same components.

[0029] like Figure 1-4 As shown, this utility model provides an automatic shoe box labeling machine, which consists of a label release component 1, a material tape recycling component 2, a label peeling component 3, a label attaching component 4, and a conveying component 5. Its working process is as follows:

[0030] Tag release: The tag is output at a constant speed through tag release component 1.

[0031] Label peeling: The label strip is peeled off from the label backing paper by the label peeling component 3, and the individual labels are separated and positioned.

[0032] Label application: Label application component 4 attaches the label precisely to the surface of the shoe box after it is adsorbed. Shoe box transport: Transport component 5 controls the movement and positioning of the shoe box and outputs the label after it is applied.

[0033] Paper recovery: The stripped paper is wound up by the material belt recovery component 2.

[0034] The specific implementation methods of each component are as follows:

[0035] 1. Label Release Assembly 1: Tape Mounting Wheel 11: Mounts the rolled label tape (including label and backing paper), which is pulled out by the traction wheel 12. A servo motor 14 drives the traction wheel 12 via a belt, controlling the label tape release speed. Feed Speed ​​Adjustment Wheel System: Consists of a feeding friction wheel 15 with a silicone coating and a feeding spring clamping wheel 16 with adjustable clamping force (5-20N). The friction is controlled by adjusting the clamping force of the feeding spring clamping wheel 16 with a knob, preventing the label tape from being too loose or too tight (see...). Figure 4 ).

[0036] 2. Material strip recycling assembly 2: Receiving wheel 21: Recycles the peeled bottom paper, driven by servo motor 14 through belt drive to the receiving friction wheel 22.

[0037] Take-up speed adjustment wheel system: The take-up friction wheel 22 and the take-up spring pressure wheel 23 work together to ensure that the bottom paper winding tension and the label release speed are synchronized. The friction force is controlled by adjusting the pressure of the take-up spring pressure wheel 23 by the knob to prevent the bottom paper from breaking or piling up.

[0038] 3. Label peeling component 3 (see Figure 4 The label-tearing cylinder 31 and the paper-pushing roller 32 drive the paper-pushing roller 32 to reciprocate, peeling the label off the backing paper. The label channel is formed by the label feeding plate 33 and the label pressing block 35 arranged in parallel. The channel width is continuously adjustable (10-30mm) by the bolts fixing the label dragging plate 36 to accommodate labels of different sizes. Guiding and positioning: The label feeding plate 33 has an arc-shaped guide surface at one end near the paper-pushing roller 32 to guide the label into the channel; a roller for receiving and guiding is fixed inside the label feeding plate 33, and the roller surface is coated with polytetrafluoroethylene to reduce label friction resistance. The label pressing block 35 and the label dragging plate 36: The label pressing block 35 presses down and positions the label under the action of the pressing cylinder 38, and the label dragging plate 36 supports the bottom of the label to ensure it is flat. The photoelectric sensor 37 uses an infrared reflective sensor to trigger the action of the attaching component 4 after detecting that the label is in place.

[0039] 4. Label attaching component 4 (see Figure 4 Vacuum nozzles 42 are arranged in a rectangular array (or concentric circles), each nozzle connected to a negative pressure source via an independent air path. The suction force can be individually adjusted (e.g., controlled by an air valve) to accommodate labels of different materials. The XY moving module 43 consists of linear guides driven by a servo motor, moving the vacuum nozzles 42 along a preset path to precisely attach the labels to the shoe box surface. The blocking cylinder 44 rises at a preset position on the transmission component 5, blocking the shoe box and positioning it to ensure consistent label placement.

[0040] 5. Conveying Component 5: Driven by drive motor 52, the shoe box moves to the labeling station along the conveyor belt. Linkage Control: Drive motor 52 and servo motor 14 are linked by signals, synchronizing the start and stop of the conveyor belt with the label release and application actions.

[0041] The method of using this utility model is as follows:

[0042] 1. Shoe box positioning: When the shoe box moves to the labeling station with the conveyor belt 51, the blocking cylinder 44 rises and the shoe box stops;

[0043] 2. Label peeling: The label strip is peeled off by the pusher roller 32, and a single label enters the label channel, where it is positioned by the pressure block 35 and the drag plate 36;

[0044] 3. Adsorption and attachment: After the photoelectric sensor 37 detects that the label is in place, the vacuum nozzle 42 adsorbs the label, and the XY moving module 43 moves the nozzle to the surface of the shoe box, releasing the negative pressure to complete the attachment.

[0045] 4. Reset and Cycle: The blocking cylinder 44 retracts, and the shoe box is output with the conveyor belt; the bottom paper is collected by the receiving wheel 21, and new label tapes are continuously released to enter the next cycle.

[0046] This utility model is an automatic shoe box labeling machine. Through the cooperation of a servo motor and a friction wheel system, it achieves precise synchronization of label tape release and retrieval, avoiding jamming or breakage. The label channel width is adjustable, and the vacuum suction force is independently controlled to adapt to labels of different sizes and materials. Low friction loss: the polytetrafluoroethylene coating of the label plate 34 reduces label wear and ensures label integrity. Precise application: the photoelectric sensor and XY movement module closed-loop control ensure that the labeling position error is within ±0.5mm.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
