Description

Technical Field

[0001] This utility model relates to the field of packaging material processing technology, and in particular to a feeding mechanism. Background Technology

[0002] Packaging materials play a crucial protective role in product transportation, storage, and sales. Common packaging materials include EPE (expanded polyethylene), cardboard, polyethylene (PE), and polyvinyl chloride (PVC). Among these, EPE, as a new type of environmentally friendly packaging material, is widely used in many packaging applications due to its excellent comprehensive performance. Specifically, EPE possesses excellent physical cushioning properties, effectively preventing shock and impact, and exhibits good resilience and toughness. Furthermore, it also possesses water-proof, moisture-proof, sound-insulating, and heat-insulating properties, and can be repeatedly recycled, aligning with current green and environmentally friendly principles. Simultaneously, EPE's strong plasticity makes it suitable for packaging various irregularly shaped products, and its excellent chemical resistance makes it outstanding in packaging various industrial products, electronic products, and fragile items, making it one of the ideal packaging materials.

[0003] Despite the superior performance of packaging materials themselves, in practical applications, especially in industrialized mass production scenarios, a series of subsequent processing techniques are still required to achieve efficient and stable packaging structures. Taking lamination as an example, the manufacturing process typically involves bonding two or more pieces of packaging material together to improve the overall protective capabilities and adaptability of the packaging. However, many packaging materials are inherently non-moldeable or have irregular structures, making the lamination process complex and necessitating the use of specialized lamination equipment.

[0004] Currently, commonly used laminating equipment typically involves a spraying system uniformly applying adhesive to the surface of one package. A gripping mechanism then precisely picks up another package and laminates it to the glued package. During operation, the laminating equipment uses a feeding mechanism to transport the packages. Adhesive application is performed during this transport to ensure successful lamination. Existing feeding mechanisms usually use conveyor belts. However, because the conveyor belt rotates in a closed loop, placing the package directly on it and having the adhesive application component above it press and apply adhesive can cause significant heat and pressure changes at the glued contact surface, leading to damage. Utility Model Content

[0005] The technical problem to be solved by this utility model is: to solve the problem of damage to the adhesive contact surface of the packaging.

[0006] To solve the above-mentioned technical problems, this utility model provides a feeding mechanism, including: a base frame, the base frame being provided with a slide rail; an adhesive application assembly, the adhesive application assembly being disposed on the base frame, the adhesive application assembly being provided with a uniform adhesive roller, the uniform adhesive roller being located above the slide rail; and a support platform, the support platform being slidably disposed on the slide rail, the support platform being provided with a functional part, the functional part being used to control the angle between the side of the workpiece closest to the adhesive application assembly and the rotation axis of the uniform adhesive roller to be within the range of 2°-10°, when the support platform slides under the uniform adhesive roller via the slide rail, the uniform adhesive roller applies adhesive to the workpiece on the functional part.

[0007] Furthermore, the functional part is provided with a groove for placing the workpiece, and the groove wall limits the range of the angle formed between the side of the workpiece closest to the glue application assembly and the axis of rotation of the glue application roller.

[0008] Furthermore, the functional part is provided with two protrusions, and the line connecting the protrusions forms an angle between the axis of rotation of the glue-spreading roller and the protrusions, which is in the range of 2°-10°.

[0009] Furthermore, the glue application assembly includes a bracket, a glue tank, a glue adjusting component, a baffle, and the glue spreading roller. The glue tank is disposed on the bracket, and a discharge port is provided at the bottom of the glue tank. The glue adjusting component is disposed on the discharge port, which is located above the baffle. The baffle is inclinedly disposed on the bracket, and the bottom of the baffle abuts against the glue spreading roller. The glue spreading roller is rotatably disposed on the bracket.

[0010] Furthermore, the bracket is equipped with a vertically oriented adjusting screw and a knob on one end of the adjusting screw. When the knob is rotated, the bracket rises or falls vertically.

[0011] Furthermore, the bracket is also provided with an adjusting torsion bar, which engages with the knob to drive the adjusting screw to rotate.

[0012] Furthermore, the bracket is also provided with a fixing rod and claws disposed on the fixing rod. The claws abut against the lower side of the glue-spreading roller. There are multiple claws, which are equidistantly arranged along the fixing rod.

[0013] Furthermore, the bottom of the support platform is provided with a slider, the slide rail is long and narrow, and the slider slides on the slide rail.

[0014] Furthermore, the slide rails are provided in two quantities, and the two slide rails are arranged opposite each other on both sides of the support platform, with at least two sliders sliding on the same slide rail.

[0015] Furthermore, it also includes a feeding drive unit connected to the support platform to drive the support platform to move along the slide rail.

[0016] Compared with the prior art, the feeding mechanism provided in this utility model embodiment has the following advantages: by placing the packaging to be bonded in the functional part of the bearing platform, the side of the packaging and the rotating shaft of the glue roller form an angle range of 2°-10°. The tilt angle changes the contact between the packaging and the glue roller from an instantaneous line-to-surface impact to a gradual line contact, avoiding the thermal shock caused by instantaneous large-area contact, thereby reducing damage to the glue contact surface.

[0026] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope. It should be noted that, unless otherwise specifically stated, the relative arrangement and numerical values ​​of the components and steps described in these examples do not limit the scope of this utility model.

[0027] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0029] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0031] like Figures 1 to 4 As shown in the figure, this utility model embodiment discloses a feeding mechanism, including: a base frame 1, an adhesive application component 2, and a support platform 3.

[0032] The base frame 1 is equipped with a slide rail 11; the glue application assembly 2 is mounted on the base frame 1 and is equipped with a glue-spreading roller 25, which is located above the slide rail 11; the support platform 3 is slidably mounted on the slide rail 11 and is equipped with a functional part 31. The functional part 31 is used to control the angle α between the side of the workpiece closest to the glue application assembly 2 and the rotation axis of the glue-spreading roller 25 to be within the range of 2°-10°. When the support platform 3 slides under the glue-spreading roller 25 via the slide rail 11, the glue-spreading roller 25 applies glue to the workpiece on the functional part 31.

[0033] The feeding mechanism of this application places the package to be bonded in the functional part 31 of the bearing platform 3, so that the side of the package and the rotating shaft of the glue roller form an angle α ranging from 2° to 10°. The tilt angle changes the contact between the package and the glue roller from an instantaneous line-to-surface impact to a gradual line contact, avoiding the thermal shock caused by instantaneous large-area contact, thereby reducing damage to the glue contact surface.

[0034] By setting the functional part 31 on the support platform 3 to form an angle of 2° to 10° with the rotating shaft of the glue-coating roller, the packaging achieves a gradual contact from line to surface during the contact process with the glue-coating roller. A portion of the inclined contact surface of the packaging is directly exposed to the high-temperature zone, while the remaining areas heat up slowly through heat conduction. This reduces heat and pressure changes in the packaging, avoiding thermal shock caused by sudden large-area contact and effectively reducing contact surface damage caused by rapid temperature changes. The inclined structure also results in a more uniform stress distribution on the packaging, avoiding localized stress concentration caused by compression during traditional flat bonding, thereby mitigating pressure changes during the glue-coating process and improving the integrity of the finished packaging.

[0035] The movement path of the carrying platform 3 is controlled by the slide rail 11, ensuring the positional accuracy of the package during movement. Combined with the stable output of adhesive by the glue-spreading roller, the uniformity and consistency of the adhesive application are improved, which is beneficial to the smooth progress of subsequent bonding processes. By setting up the functional unit 31, it can adapt to packages of different shapes, and the position and angle of the package are adjustable. The adjustable angle also makes the feeding mechanism suitable for the glue application process of various types of packages, with good versatility and promising prospects for industrial application.

[0036] Specifically, the functional part 31 is provided with a groove for placing the workpiece, and the groove wall limits the angle range α between the side of the workpiece closest to the glue application assembly and the axis of the glue application roller.

[0037] Specifically, the functional part 31 is provided with two protrusions, and the line connecting the two protrusions forms an angle α with the rotating shaft of the glue roller, which is 2°-10°. The side of the package is fixed by the two protrusions.

[0038] Specifically, functional part 31 is a mold for placing workpieces, and the package is placed inside the mold. The mounting cavity of the mold makes the side of the package form an angle α between the rotating shaft of the glue-spreading roller and the angle α between 2° and 10°.

[0039] like Figure 2 and Figure 4 As shown, in an optional embodiment of the utility model, the glue application assembly 2 includes a bracket 21, a glue tank 22, a glue adjusting component 23, a baffle 24, and a glue spreading roller. The glue tank 22 is disposed on the bracket 21, and a discharge port 201 is provided at the bottom of the glue tank 22. The glue adjusting component 23 is disposed on the discharge port 201, and the discharge port 201 is located above the baffle 24. The baffle 24 is inclinedly disposed on the bracket 21, and the bottom of the baffle 24 abuts against the glue spreading roller. The glue spreading roller is rotatably disposed on the bracket 21.

[0040] By incorporating an adhesive tank 22, an adhesive regulating component 23, and an inclined baffle 24 into the adhesive coating assembly 2, the adhesive is slowly released from the bottom outlet 201 of the adhesive tank 22 and evenly distributed onto the surface of the coating roller under the guidance of the baffle 24. This ensures a stable adhesive supply and uniform coating effect during the coating process. Furthermore, the adhesive regulating component 23 at the outlet 201 allows for precise control of the adhesive flow rate according to different process requirements, preventing excessive adhesive supply during coating that could lead to adhesive accumulation, contamination, or waste on the packaging surface, thus improving product yield and adhesive utilization efficiency.

[0041] The glue coating assembly 2 adopts a modular combination structure. The glue tank 22, adjusting components, baffle 24, and coating roller are compactly integrated, easy to install, easy to clean and maintain, and conducive to the long-term stable operation of the equipment. By abutting the bottom of the baffle 24 against the coating roller, the glue is continuously and controllably carried out for coating during the rolling process. It can adapt to the continuous production rhythm, meet the glue coating needs of different packaging sizes, has a wide range of applications, and high industrial application value.

[0042] like Figure 2 and Figure 4 As shown, in an optional embodiment of the utility model, the bracket 21 is provided with an adjusting screw 211 arranged in the vertical direction and a knob 212 provided on one end of the adjusting screw 211. When the knob 212 is rotated, the bracket 21 rises or falls in the vertical direction.

[0043] By installing a vertical adjusting screw 211 and a matching knob 212 on the bracket 21, the operator can rotate the knob 212 to raise and lower the entire glue application assembly 2 vertically, thereby adjusting the relative position between the glue application roller and the packaged product to accommodate packages of different thicknesses or specifications, improving the equipment's versatility and flexibility. The height-adjustable structure allows for fine-tuning of the contact angle and pressure between the glue application roller and the packaged product according to actual working conditions, helping to precisely control the glue application thickness and contact force, avoiding over-pressure or insufficient contact, and improving the uniformity of glue application and the stability of subsequent bonding.

[0044] By employing a knob 212 combined with a lead screw, adjustments can be made without complex tools. The adjustment process is smooth and precise, allowing on-site workers to quickly respond to production needs or change product specifications, thereby improving production efficiency. The adjustment structure has strong mechanical stability and is not easily loosened, making it suitable for high-frequency adjustments in various industrial environments, ensuring the consistency and reliability of the equipment during long-term operation.

[0045] like Figure 2 and Figure 4 As shown, in an optional embodiment of the utility model, the bracket 21 is further provided with an adjusting torsion bar 213, which engages with the knob 212 to drive the adjusting screw 211 to rotate.

[0046] By adding an adjusting torsion bar 213 to the bracket 21 and engaging it with the knob 212, a stable drive for the adjusting screw 211 is achieved when the adjusting torsion bar 213 rotates, improving the transmission efficiency and response speed during height adjustment of the adhesive application assembly 2. The engagement structure between the adjusting torsion bar 213 and the knob 212 effectively reduces slippage or jamming caused by manual operation of the knob 212 during adjustment, making the overall adjustment process smoother and more stable, and enhancing the operating feel and reliability of the equipment.

[0047] like Figure 2 and Figure 3As shown, in an optional embodiment of the utility model, the bracket 21 is further provided with a fixing rod 214 and a claw 215 disposed on the fixing rod 214, the claw 215 abutting against the lower side of the glue-spreading roller.

[0048] By setting a fixing rod 214 and multiple claws 215 on the bracket 21, these claws 215 abut against the lower side of the coating roller, effectively assisting the coating roller in maintaining a balanced state of adhesive application during rotation, thereby achieving uniform distribution of adhesive on the roller surface and improving coating quality. The continuous contact of the claws 215 with the lower side of the coating roller provides appropriate physical intervention, which can limit adhesive accumulation or local thick coating, ensuring the consistency and uniformity of the adhesive surface of the packaged parts, which is beneficial to the precision control of subsequent bonding processes. The combined action of multiple claws 215 on the coating roller helps to prevent coating deviation caused by uneven loading or deflection of the roller body, further improving the stability of equipment operation and product consistency.

[0049] like Figure 2 and Figure 4 As shown, in an optional embodiment of the utility model, there are multiple claws 215, which are equidistantly arranged along the fixing rod 214.

[0050] Specifically, the claw 215 is rotatably mounted on the fixed rod 214, and the angle of the claw 215 on the fixed rod 214 can be adjusted.

[0051] By equidistantly arranging multiple claws 215 along the fixed rod 214, a balanced force and contact distribution can be formed on the underside of the coating roller, effectively controlling the flow state of the adhesive on the roller surface, making the adhesive distribution more uniform, and avoiding localized over- or under-coating. The claws 215 adopt a rotatable mounting structure, allowing for flexible adjustment of their angle on the fixed rod 214 according to actual working conditions, to adapt to coating rollers of different sizes, shapes, or coating process requirements, effectively improving the adaptability and operational flexibility of the equipment. The adjustable angle of the claws 215 allows the operator to fine-tune the contact point and contact pressure of the coating roller based on parameters such as adhesive viscosity and flow rate, thereby more precisely controlling the adhesive layer thickness and coating range, ensuring high-quality coating results. The distribution of multiple claws 215 combined with the rotating structure results in a compact and reasonable overall structure, facilitating disassembly, cleaning, and maintenance, making it suitable for high-frequency, continuous industrial production environments.

[0052] like Figure 1 and Figure 3As shown, in an optional embodiment of the utility model, the top edge of the support platform 3 is provided with a scale. The scale on the top edge of the support platform 3 helps operators calibrate the position when placing packaging or functional parts 31, thereby ensuring accurate positioning of the packaging during the gluing process and improving overall bonding quality. The scale can serve as a reference, allowing operators to quickly determine whether the angle formed by the functional part 31 and the gluing roller is within the preset range of 2°-10°, achieving visualization and standardization of angle adjustment and improving adjustment efficiency. The scale markings allow for quick replication and restoration of placement positions in repetitive operations, reducing deviations caused by visual errors and improving production efficiency and consistency. The scale has universal adaptability, meeting the positioning requirements of different sized packaging on the support platform 3, thus enhancing the applicability and flexibility of the feeding mechanism.

[0053] like Figure 2 and Figure 3 As shown, in an optional embodiment of the utility model, the bottom of the support platform 3 is provided with a slider 32, the slide rail 11 is elongated, and the slider 32 is slidably mounted on the slide rail 11.

[0054] By installing a slider 32 at the bottom of the carrying platform 3 and allowing it to slide smoothly on the elongated slide rail 11, the carrying platform 3 is effectively guided to slide smoothly along a fixed path, ensuring that the packaged item maintains a stable posture as it moves under the glue-coating roller, thus improving the glue coating accuracy. The cooperation between the slider 32 and the slide rail 11 reduces the frictional resistance during the platform's sliding process, making the sliding smoother and helping to improve the equipment's operating efficiency and service life. The elongated slide rail 11 provides a larger guide length, enabling the platform to have higher repeatability and guiding stability during back-and-forth sliding, which is beneficial for the consistent control of the packaged item in multiple glue coating operations.

[0055] Specifically, the slide rail 11 includes a stabilizing part, a load-sharing part, and a guiding part; the load-sharing part is disposed between the stabilizing part and the guiding part; a guiding groove is provided on the load-bearing slider 32, and the guiding part is embedded in the guiding groove; a hook block is provided in the guiding groove, and the hook block abuts against the load-sharing part; pressure relief surfaces are provided on both sides of the load-sharing part; the pressure relief surfaces on both sides are inclined in a gradually approaching manner from the stabilizing part to the guiding part; the hook blocks are disposed opposite each other on both sides of the inner wall of the guiding groove, the hook blocks on both sides extend towards each other, and the hook blocks on both sides abut against the pressure relief surfaces on both sides; the guiding part is provided with a cylindrical structure, the guiding groove is in the shape of an arc-shaped groove, and the guiding part fits against the inner wall of the guiding groove.

[0056] like Figure 1 and Figure 2 As shown, in an optional embodiment of the utility model, the number of slide rails 11 is two, and the two slide rails 11 are arranged opposite to each other on both sides of the support platform 3. At least two sliders 32 are slidably mounted on the same slide rail 11.

[0057] By setting two slide rails 11 on both sides of the carrying platform 3, and at least two sliders 32 on the same slide rail 11, a more balanced force distribution can be achieved, ensuring that the carrying platform 3 remains stable during sliding and avoiding platform tilting or offset due to insufficient support on one side, thus improving the overall operational stability. The dual slide rails 11 provide better guiding capability, allowing the carrying platform 3 to slide along a precise path, thereby reducing errors during sliding, improving the positioning accuracy of the packaged items and the uniformity of adhesive application, and enhancing work efficiency and product quality. Multiple sliders 32 distributed on the slide rails 11 effectively distribute the platform load, increasing the system's load-bearing capacity and adapting to the transportation needs of heavier or more complex packages, enhancing the equipment's applicability and load-bearing capacity. The cooperation between the dual slide rails 11 and multiple sliders 32 allows the feeding mechanism to better resist external vibrations and impacts under high-speed movement or frequent operation, extending the equipment's service life and maintaining long-term efficient and stable operation.

[0058] like Figure 2 and Figure 4 As shown, in an optional embodiment of the utility model, a feeding drive 4 is also included. The feeding drive 4 is connected to the support platform 3 to drive the support platform 3 to move along the slide rail 11.

[0059] By incorporating a feeding drive unit 4 into the loading mechanism and connecting it to the carrying platform 3, automated movement of the carrying platform 3 is achieved. This not only reduces reliance on manual operation but also significantly improves the automation level of the production line and enhances overall work efficiency. The feeding drive unit 4 can precisely control the moving speed and position of the carrying platform 3 along the slide rail 11, thereby ensuring the accuracy of each movement, avoiding deviations caused by manual operation, and guaranteeing the positioning accuracy of the packaged parts and the consistency of adhesive application. The application of the feeding drive unit 4 can reduce the frequent manual handling and adjustment of the platform, reduce the labor intensity of workers, and improve the stability and operational efficiency of the production process, especially in large-scale or high-frequency production environments. The feeding drive unit 4 can flexibly adjust the moving speed and spacing of the carrying platform 3 to adapt to different packaging specifications and production needs, providing greater flexibility and ensuring that the equipment can handle diverse adhesive application operations.

[0060] Specifically, the feeding drive component 4 includes a rotating shaft, a feeding motor, a feeding drive wheel, a feeding driven wheel, and a feeding belt; the rotating shaft is rotatably connected to the base frame 1, and the feeding motor is connected to the rotating shaft to drive the rotating shaft to rotate; the feeding drive wheel is mounted on the rotating shaft and rotates together with the rotating shaft; the feeding driven wheel is rotatably connected to the base frame 1, and the feeding belt is sleeved on the outside of the feeding drive wheel and the feeding driven wheel, and the feeding belt is connected to the bearing platform 3.

[0061] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
