Description

Technical Field

[0001] This utility model relates to the field of leather processing equipment technology, and in particular to a leather coating equipment. Background Technology

[0002] Leather is a material made from animal hides through chemical and physical processing such as hair removal and tanning. Its core characteristics are flexibility and durability, while retaining the natural texture and breathability of the animal hides.

[0003] Currently, in the leather processing industry, the gluing process largely relies on semi-automated equipment or manual operation, which suffers from the following technical shortcomings: Firstly, manual gluing depends on operator experience, resulting in uneven glue thickness, large trajectory deviations, low efficiency, and high labor intensity, making it unsuitable for mass production. Secondly, some automated gluing equipment uses a single bearing to support the rotating shaft, leading to decreased coaxiality after long-term use and exacerbating leather rotation and swaying. The moving modules of the gluing device lack precise guidance, resulting in large gluing position deviations. Position detection cameras are mostly fixed installations, unable to adjust their height according to leather type, resulting in low detection accuracy and susceptibility to lens contamination by glue mist. Control systems are often decentralized, with cluttered button layouts, making them prone to misoperation leading to equipment damage or safety accidents. Furthermore, glue supply pipelines often leak due to poor sealing, wasting glue, contaminating equipment and leather, and increasing cleaning costs. These problems result in unstable gluing quality, high failure rates, and high maintenance costs for existing equipment, making it difficult to meet the high-precision requirements of leather products for gluing processes.

[0011] A further improvement to the above technical solution is that the glue application device includes a connecting plate, a glue bucket, and a glue application valve; the connecting plate is connected to the vertical linear module, and the side of the connecting plate opposite to the vertical linear module is provided with at least two parallel fixing rings for axially fixing the glue bucket; the glue bucket is used to supply glue to the glue application valve; the glue application valve is connected to the glue bucket through an adapter.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] like Figures 1 to 6The image shows an embodiment of the present invention, relating to a leather gluing device, including a device body 10. The device body 10 includes a frame 20, a positioning and rotating mechanism 30, and a moving gluing mechanism 40. The frame 20 is used to install and fix the positioning and rotating mechanism 30 and the moving gluing mechanism 40. The positioning and rotating mechanism 30 includes a positioning disc 31, a rotating shaft 50, a transmission gear 32, a transmission rack 60, and a drive cylinder 33. The positioning disc 31 is used to fix the leather to be glued. The top end of the rotating shaft 50 is connected to the bottom of the positioning disc 31, and its bottom end is connected to the transmission gear 32. The transmission gear 32 is connected to the transmission... The rack and pinion 60 are engaged; the output end of the drive cylinder 33 is connected to a drive block 34, one end of which is connected to the transmission rack and pinion 60, for transmitting the output power of the drive cylinder 33 to the transmission rack and pinion 60, thereby driving the transmission gear 32 to rotate; the moving glue applicator 40 includes a moving device 41, a glue applicator 70, and a position detection camera 42; the moving device 41 is connected to the glue applicator 70, for driving the glue applicator 70 to move above the positioning disk 31; the glue applicator 70 is used to apply glue to the leather to be glued; the position detection camera 42 is used to detect the position of the leather to be glued on the positioning disk 31. Specifically, the frame 20 serves as the equipment foundation, providing a stable mounting and fixing carrier for the positioning and rotating mechanism 30 and the moving glue application mechanism 40, avoiding glue application deviations caused by loose components and improving the overall structural rigidity of the equipment. In the positioning and rotating mechanism 30, the positioning disc 31 can tightly fix the leather to be glued, preventing the leather from shifting during the glue application process and ensuring accurate glue application. Compared with traditional belt drives or chain drives, the meshing transmission structure of the rotating shaft 50, transmission gear 32, and transmission rack 60 has smaller transmission gaps and smoother power transmission, and can accurately control the rotation speed and angle of the leather. It adapts to different gluing trajectory requirements; the drive cylinder 33 provides stable power to the transmission rack 60, with fast response speed and controllable output force, and can flexibly adjust the rotation drive force according to the leather thickness or gluing process; the moving device 41 of the moving gluing mechanism 40 can drive the gluing device 70 to move precisely above the positioning disk 31, and cooperate with the position detection camera 42 to detect the leather position in real time, realize the closed-loop control of positioning, movement and gluing, avoid the error of manual positioning, significantly improve the gluing efficiency and consistency, and at the same time reduce the intensity of manual operation and reduce material waste caused by human error.

[0021] like Figure 1As shown, a processing platform 21 is provided above the frame 20, and the processing platform 21 has an opening 22; an industrial control computer 23 is provided above the opening 22; the industrial control computer 23 is electrically connected to a first control button group 24 and a second control button group 25, which are respectively located on both sides of the opening 22; the first control button group 24 is used to control the start and stop of the positioning and rotating mechanism 30, and the second control button group 25 is used to control the start and stop of the moving glue application mechanism 40. Specifically, the processing platform 21 provides a flat operating surface for leather gluing, and its opening 22 can accommodate the installation of components while optimizing the equipment space layout. The industrial control computer 23 serves as the control core, realizing centralized control of the positioning and rotating mechanism 30 and the moving gluing mechanism 40. Compared with decentralized control, it reduces circuit redundancy and facilitates parameter debugging and fault diagnosis. The first control button group 24 and the second control button group 25 respectively control the positioning and rotating mechanism 30 and the moving gluing mechanism 40, and are located on both sides of the opening 22. On the one hand, this avoids the risk of mechanism linkage caused by misoperation of a single button group. On the other hand, the operator can quickly switch the control object according to the actual condition of the leather, improving the convenience of operation. At the same time, the physically separated button layout also reduces the probability of accidental touch and ensures the safe operation of the equipment.

[0022] like Figure 2 and Figure 3 As shown, the rotating shaft 50 is fitted through and into the processing platform 21. A first bearing seat 51 is mounted on the portion of the rotating shaft 50 above the processing platform 21, and the first bearing seat 51 is fixed to the upper surface of the processing platform 21. A second bearing seat 52 is mounted on the portion of the rotating shaft 50 below the processing platform 21, and the second bearing seat 52 is fixed to the lower surface of the processing platform 21. Specifically, the fitting between the rotating shaft 50 and the processing platform 21 must withstand the radial and axial forces during leather rotation. The first bearing seat 51 (above the processing platform 21) and the second bearing seat 52 (below the processing platform 21) form an upper and lower clamping support. Compared to a single bearing seat support, this effectively counteracts the radial sway of the rotating shaft 50, reduces bending deformation of the shaft due to uneven force, and extends the service life of the rotating shaft 50. The bearing seats are fixed to the upper and lower surfaces of the processing platform 21, ensuring that the support reference is consistent with the processing platform 21, avoiding coaxiality errors of the rotating shaft 50 due to support position offset, thereby ensuring the rotational accuracy of the positioning disc 31. When the coaxiality of the rotating shaft 50 is improved, the eccentricity of the leather during rotation is significantly reduced, and the roundness or flatness of the adhesive application trajectory is better. It is especially suitable for the adhesive application needs of round or ring-shaped leather, and solves the problem of uneven adhesive edges caused by rotational offset under the traditional single support structure.

[0023] like Figure 3As shown, the top end of the transmission rack 60 is connected to a guide rail 61, and at least two guide sliders 62 are slidably fitted on the guide rail 61. The side of the guide slider 62 facing away from the guide rail 61 is fixedly connected to the lower surface of the processing platform 21. Specifically, the transmission rack 60, as a key component driving the rotating shaft 50, directly affects the rotational accuracy of the transmission gear 32. After the guide rail 61 is connected to the transmission rack 60, it can restrict the rack to move only in a preset direction, avoiding lateral deviation caused by uneven force on the rack. The design of at least two guide sliders 62, compared with a single slider, can form two-point support, further improving the smoothness of the rack's movement, reducing the gap wobble between the rail and the slider, ensuring that the meshing depth of the rack and the transmission gear 32 is consistent, and avoiding tooth skipping or jamming failures caused by changes in meshing gap. The guide slider 62 is fixed to the lower surface of the processing platform 21, using the platform as a reference to ensure the installation accuracy of the rail, thereby keeping the rack's movement trajectory perpendicular to the axis of the rotating shaft 50, ensuring that the driving force is accurately transmitted along the length of the rack, and ultimately improving the uniformity of the rotation of the positioning disc 31, avoiding uneven glue thickness caused by sudden changes in the speed of leather rotation.

[0024] like Figure 2 As shown, the cylinder body of the drive cylinder 33 is fixedly connected to the lower surface of the processing platform 21. Specifically, the cylinder body of the drive cylinder 33 is fixed to the lower surface of the processing platform 21. Compared with the floating installation, this eliminates cylinder body wobbling during operation: when the cylinder piston rod extends and retracts to push the transmission rack 60, if the cylinder body wobbles, the thrust direction will deviate, thus affecting the rack's movement accuracy. With the cylinder body fixed, the thrust can be transmitted completely along the rack's length direction, resulting in less power loss. At the same time, fixing the cylinder body to the bottom of the platform utilizes the unused space below the platform, avoiding the cylinder occupying the operating space above the processing platform 21, optimizing the overall equipment layout, and ensuring that only adhesive application and inspection-related components are retained above the processing platform 21, reducing visual obstruction for operators and improving operational convenience. In addition, the fixed installation also facilitates cylinder maintenance and repair, reduces the probability of failure due to cylinder body loosening, and ensures the continuous and stable operation of the positioning rotation mechanism 30.

[0025] like Figure 2As shown, the moving device 41 includes a horizontal linear module 43 and a vertical linear module 44; the horizontal linear module 43 is used to drive the vertical linear module 44 to translate horizontally, and its bottom ends are respectively connected to the support base 45, the bottom of the support base 45 is fixedly connected to the upper surface of the processing platform 21; the vertical linear module 44 is connected to the glue application device 70 and the position detection camera 42 respectively, and is used to drive the glue application device 70 and the position detection camera 42 to translate vertically. Specifically, the horizontal linear module 43 can drive the vertical linear module 44 to move laterally along the processing platform 21, achieving a wide coverage of the gluing device 70 and the position detection camera 42, adapting to the gluing needs of leathers of different sizes; the vertical linear module 44 can drive the gluing device 70 and the camera to move vertically, on the one hand, adjusting the gluing height of the gluing device 70 according to the thickness of the leather, such as raising the height of the gluing valve 73 to avoid scratching thick leather, and lowering the height to ensure gluing adhesion for thin leather, on the other hand, adjusting the detection height of the camera to ensure accurate camera focusing; the shim 45 connects the horizontal linear module 43 and the processing platform 21, and by raising the installation height of the horizontal module, interference between the module and other components on the processing platform 21 can be avoided, while keeping the moving trajectory of the horizontal module parallel to the rotation plane of the positioning disk 31, ensuring that the distance between the gluing device 70 and the leather surface is constant when the gluing device 70 moves, further improving the uniformity of the gluing thickness.

[0026] like Figure 4 As shown, the glue application device 70 includes a connecting plate 71, a glue bucket 72, and a glue application valve 73; the connecting plate 71 is connected to the vertical linear module 44, and the side of the connecting plate 71 facing away from the vertical linear module 44 is provided with at least two parallel fixing rings 74 for axially fixing the glue bucket 72; the glue bucket 72 is used to supply glue to the glue application valve 73; the glue application valve 73 is connected to the glue bucket 72 through an adapter 75. Specifically, the connecting plate 71 serves as the connecting carrier between the vertical linear module 44 and the glue applicator 70, enabling the overall assembly and disassembly of the glue applicator 70 for easy maintenance or replacement of glue applicators 73 of different specifications. At least two parallel fixing rings 74 axially fix the glue tank 72, preventing tilting of the glue tank 72 due to gravity or vibration, compared to a single fixing point, thus avoiding glue leakage or pressure fluctuations. The adapter 75 connects the glue tank 72 and the glue applicator 73, which, compared to a direct rigid connection, can accommodate installation angle deviations between the glue tank 72 and the glue applicator 73. The sealing structure of the adapter 75, such as O-rings, effectively prevents glue leakage, especially suitable for high-viscosity glues such as PU glue, preventing glue curing and clogging of the pipeline. The stable supply of glue from the glue tank 72 to the glue applicator 73, combined with the precise control of the glue applicator 73, enables on-demand glue dispensing, reducing glue waste and preventing glue interruptions or accumulation due to unstable glue supply, thus improving glue application quality.

[0027] like Figure 4 As shown, a fine-tuning slide 46 for fine-tuning the height of the position detection camera 42 is mounted on one side. A protective baffle 47 is connected to the side of the position detection camera 42 away from the fine-tuning slide 46, and the protective baffle 47 is connected to the side of the fine-tuning slide 46. Specifically, the fine-tuning slide 46 can adjust the camera height at the millimeter or even micrometer level. Compared with the coarse adjustment relying solely on the moving device 41, it can accurately adapt to the detection needs of different leathers. For example, the camera height needs to be adjusted to avoid glare for highly reflective leather, and the height needs to be lowered to improve detection sensitivity for dark leather, ensuring that the camera can clearly capture the leather edge or positioning mark, providing accurate data for glue application positioning. The protective baffle 47 is connected to the side of the camera away from the fine-tuning slide 46 and fixed to the side of the fine-tuning slide 46, forming lateral protection for the camera. It can block glue mist, dust or leather debris splashed during the glue application process, preventing contaminants from adhering to the camera lens and causing a decrease in detection accuracy. At the same time, it prevents the camera from being accidentally bumped, extends the camera's service life, and reduces equipment downtime caused by camera failure.

[0028] like Figure 5 and Figure 6 As shown, a mounting plate 48 is connected to the side of the fine-tuning slide 46 away from the position detection camera 42. An adjustment drive assembly 80 is located on the rear side of the mounting plate 48. The adjustment drive assembly 80 is used to drive the fine-tuning slide 46 to rise and fall to adjust the height of the position detection camera 42. Specifically, the mounting plate 48 serves as a connecting bridge between the fine-tuning slide 46 and the adjustment drive assembly 80, integrating the fine adjustment function of the fine-tuning slide 46 with the overall lifting function of the drive assembly. This results in a compact structure and convenient installation. The adjustment drive assembly 80 can drive the fine-tuning slide 46 to rise and fall as a whole, enabling coarse adjustment of the camera height, such as adapting to processing platforms 21 of different heights or leather stacking scenarios. The fine-tuning slide 46 is responsible for fine adjustment, such as compensating for minor errors after coarse adjustment. The combination of the two can cover a wider range of height adjustments, resolving the contradiction of small range or low precision in traditional single adjustment structures. Simultaneously, the overall lifting design facilitates raising the camera during equipment maintenance, preventing operators from bumping into the camera while repairing other components, thus improving maintenance safety.

[0029] like Figure 6As shown, the adjustment drive assembly 80 includes an L-shaped connecting plate 81, an auxiliary slider 82, an auxiliary slide rail 83, and an adjustment cylinder 84; one side of the L-shaped connecting plate 81 is fixedly connected to the mounting plate 48; the auxiliary slider 82 is connected to the L-shaped connecting plate 81 and slides in cooperation with the auxiliary slide rail 83; the auxiliary slide rail 83 is fixed to one side of the adjustment cylinder 84; the adjustment cylinder 84 is used to drive the L-shaped connecting plate 81 to move up and down in the vertical direction to adjust the height of the position detection camera 42. Specifically, the bending structure of the L-shaped connecting plate 81 can accommodate the spatial positional deviation between the mounting plate 48 and the auxiliary slider 82. Compared with straight plate connections, it can reduce dimensional interference during component installation. At the same time, the L-shaped structure has stronger rigidity, which can avoid lifting and lowering offset caused by deformation of the connecting components. The sliding cooperation between the auxiliary slider 82 and the auxiliary slide rail 83 provides guidance for the lifting and lowering of the L-shaped connecting plate 81, restricting it to move only in the vertical direction, avoiding jamming or tilting caused by the skewed thrust of the adjusting cylinder 84, and ensuring a smooth and wobbly lifting and lowering process. The auxiliary slide rail 83 is fixed to one side of the adjusting cylinder 84, keeping the slide rail and the power output direction of the cylinder parallel, further improving the guiding accuracy. The adjusting cylinder 84, as a power source, has a stable output force and controllable stroke. The lifting and lowering height can be preset by the industrial control computer 23. Compared with manual adjustment, it not only saves time but also avoids errors caused by manual adjustment, ensuring that the camera height is consistent after adjustment by different operators, and guaranteeing the stability of detection accuracy.

[0030] The working principle of this utility model is as follows: First, the leather to be coated is fixed on the positioning disc 31 of the positioning and rotating mechanism 30. The equipment is started via the industrial control computer 23, and the operator presses the first control button group 24 to start the positioning and rotating mechanism 30: the piston rod of the drive cylinder 33 extends and retracts, driving the rack drive block 34 and the transmission rack 60 to move along the guide rail 61. The transmission rack 60 meshes with the transmission gear 32, thereby driving the rotating shaft 50 and the positioning disc 31 to rotate, so that the leather rotates synchronously. At the same time, the second control button group 25 is pressed to start the moving coating mechanism 40. The horizontal linear module 43 drives the vertical linear module 44 to move laterally along the processing platform 21, conveying the coating device 70 and the position detection camera 42 to the top of the positioning disc 31. The position detection camera 42 is adjusted by the drive component 80. After coarse adjustment of the height, fine focusing is performed using the fine-tuning slide 46 to detect the leather position and feed the data back to the industrial control computer 23. The industrial control computer 23 controls the vertical linear module 44 to adjust the height of the glue applicator 70 based on the detection data. Subsequently, the glue tank 72 of the glue applicator 70 supplies glue to the glue applicator valve 73 through the adapter 75. The glue applicator valve 73 opens the glue applicator according to the preset trajectory. At the same time, the positioning disc 31 drives the leather to rotate at a uniform speed, so that the glue applicator 70 forms a uniform glue layer on the surface of the leather. During the glue applicator process, the protective baffle 47 prevents glue mist from contaminating the camera lens. The industrial control computer 23 monitors the operating status of each mechanism in real time. The operator can flexibly control the start and stop of the mechanism through the separate button group. After the glue applicator is completed, each mechanism is reset, the glued leather is removed, and one glue applicator cycle is completed.

[0031] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
