Abstract
Description
Technical Field
[0001] This application relates to the field of adhesive coating machinery, and in particular to an adhesive coating mechanism, adhesive coating equipment and method. Background Technology
[0002] Some products require the application of glue to the surfaces of components during the manufacturing process, and the quality of this glue application greatly affects the quality of the final product. For example, in the shoemaking industry, glue needs to be applied to the surface of the midsole to bond the upper, straps, and outsole later on. The quality of the glue application to the midsole has a significant impact on the quality of the shoe. Applying the glue evenly and quantitatively to the designated area of the midsole is an important step in improving shoe manufacturing quality.
[0003] Traditional manual application of adhesive to the midsole surface suffers from low efficiency, poor consistency, uneven application, and easy detachment. Therefore, the industry has developed various types of automated adhesive application equipment. These devices automatically apply adhesive to the midsole surface, significantly improving efficiency and, to some extent, consistency and uniformity. However, current automated adhesive application equipment still has some problems in practical use. For example, patent CN218571563U describes an automated adhesive application device widely used in the shoe manufacturing industry. This device uses a conveyor belt to linearly transport the shoe upper to be coated, and then a coating roller is placed above the upper. The roller is controlled to descend to a suitable position to continuously apply adhesive to the linearly moving upper. While this method is fast and efficient, the conveyor belt's stability is poor, causing the upper to sway during linear movement. Even when the coating roller remains stationary and only rotates for coating, the adhesive film applied to the upper inevitably suffers from inconsistent thickness and unevenness. Therefore, the coating quality of this type of equipment is generally not high. Summary of the Invention
[0004] To improve the quality of adhesive application in products, this application provides an adhesive application mechanism, adhesive application equipment, and method.
[0005] The adhesive application mechanism provided in this application adopts the following technical solution: A glue application mechanism for applying glue to the surface of a product, comprising a glue application head and a glue dispensing assembly, wherein the glue application head has: A transverse movement device 1 is connected to a mounting plate, and the mounting plate is moved laterally by the transverse movement device 1. A shaft bracket is hinged to a mounting plate, and an adhesive roller is rotatably mounted on the shaft bracket. A push-pull device is hinged to the mounting plate. Its push-pull movable end is connected to a shaft frame, which is used to drive the shaft frame to swing around the mounting plate. The swing of the shaft frame can make the glue-applying roller contact the product to be glued. Then, the transverse movement device drives the glue-applying roller to roll against the surface of the product to be glued. Material detection element one is used to detect whether there is a product to be coated in the swing direction of the coating roller. When the material detection element one detects a product to be coated, the shaft swings in the product direction so that the coating roller contacts the product to be coated and rolls against the surface of the product to be coated. The glue dispensing assembly has a glue dispensing plate, which is located above the coating roller and connected to the shaft frame. The glue dispensing plate has glue dispensing holes, through which glue is supplied to the outer circumferential surface of the coating roller.
[0006] By adopting the above technical solution, the glue coating mechanism can move smoothly to coat products in a fixed state. The glue coating mechanism moves smoothly and with high precision. The roller will not shake during the movement, ensuring the uniformity of the glue film thickness.
[0007] Preferably, the coating head also has a driving device and a lifting device. The driving device is connected to the coating roller drive and is used to drive the coating roller to rotate. The lifting device is connected to the transverse movement device and drives the transverse movement device to rise and fall.
[0008] By adopting the above technical solutions, the height of the glue coating mechanism can be adjusted and the glue coating roller can rotate autonomously, thus better meeting the glue coating needs of different products or different specifications of the same product.
[0009] Preferably, the glue dispensing plate has a glue spreading channel inside, one end of which extends to the outer wall of the glue dispensing plate. There are multiple glue dispensing holes, which are spaced apart along the axial direction of the glue coating roller, and the multiple glue dispensing holes are connected to the glue spreading channel.
[0010] By adopting the above technical solution, the glue is evenly delivered to the outer circumference of the coating roller through multiple glue outlets, thereby improving the glue coating quality of the product. At the same time, in order to facilitate the supply of glue to multiple glue outlets, a glue distribution channel is set up to connect multiple glue outlets. With this design, it is only necessary to inject glue into the glue distribution channel, and the glue will flow into multiple glue outlets by itself in the glue distribution channel.
[0011] Preferably, the glue dispensing plate includes a first plate body and a second plate body that are sealed and fixedly connected, and the glue channel and glue dispensing hole are located in the first plate body and / or the second plate body.
[0012] By adopting the above technical solutions, the processing cost of the adhesive tape channel has been significantly reduced.
[0013] Preferably, the glue dispensing assembly further includes a pair of baffles located at both ends of the coating roller along its axial direction. The baffles are connected to the glue dispensing plate. The baffles are provided with an arc surface that fits against the outer circumferential surface of the coating roller. The glue dispensing plate is spaced apart from the outer circumferential surface of the coating roller. The pair of baffles and the glue dispensing plate together define a glue storage space above the coating roller for storing glue. The glue dispensing hole is connected to the glue storage space.
[0014] By adopting the above technical solution, the glue layer on the outer circumference of the rotating glue-coating roller is more uniform, which helps to improve the glue coating quality and also facilitates subsequent adjustment of the glue layer thickness.
[0015] Preferably, the dispensing plate is fixedly connected to the shaft frame in a height-adjustable manner through a position adjustment mechanism, and the height adjustment of the dispensing plate changes the gap width between the dispensing plate and the outer circumferential surface of the coating roller.
[0016] By adopting the above technical solution, the thickness of the adhesive layer on the outer circumference of the coating roller is adjusted, thereby adjusting the thickness of the adhesive layer coated on the product surface.
[0017] Preferably, the position adjustment mechanism includes a column and stops. The column is fixedly installed on the shaft frame, and a pair of spaced stops are fixedly installed on the column in a liftable manner. The pair of stops clamp and fix the dispensing plate.
[0018] By adopting the above technical solution, the gap width between the glue dispensing plate and the outer circumference of the glue coating roller can be quickly adjusted. Moreover, this adjustment mechanism has a simple structure, low cost, and reliable and stable adjustment quality.
[0019] In addition, this application also provides an adhesive application device, including an adhesive supply assembly and an adhesive application mechanism as described above, wherein the adhesive supply assembly has: A heating base is provided with a glue bucket with a stirring function. The glue bucket has a lid. The heating base can heat the glue in the glue bucket. A glue dispensing tube is installed on the lid of the container. One end of the glue dispensing tube extends into the glue container, and the other end is connected to the glue dispensing hole. A control valve is installed on the glue dispensing tube.
[0020] By adopting the above technical solution, the adhesive coating equipment can apply adhesive to the product with high quality.
[0021] Preferably, the adhesive coating equipment further includes a clamping mechanism for clamping and fixing the product to be coated with adhesive; The clamping mechanism has: The second transverse movement device is connected to an automatic gripper, which drives the automatic gripper to move laterally to hold the product to be coated with glue. Material detection element two is used to detect whether there is a product to be coated with glue in the lateral movement direction of the automatic gripper, so that when material detection element two detects a product to be coated with glue, the lateral movement device two drives the automatic gripper to move towards the product and clamp the product to be coated with glue.
[0022] By adopting the above technical solution, when the product to be coated is transferred to the coating equipment via the assembly line, the clamping mechanism clamps and fixes the product for the coating mechanism to apply the glue. After the coating is completed, the clamping mechanism releases the product and the product is sent away by the assembly line. In this way, the product can be automatically coated in an assembly line, which greatly improves the coating efficiency.
[0023] Preferably, the glue application equipment further includes a glue receiving container located directly below the glue application roller, which is used to collect the glue dripping from the glue application roller.
[0024] By adopting the above technical solution, the glue dripping from the coating roller can be avoided from contaminating other parts of the coating equipment and causing trouble for the cleaning operation of the coating equipment.
[0025] In addition, this application also provides a method for applying adhesive, applied to the aforementioned adhesive application equipment, comprising: Fix the product to be glued to the glue application position; Start the glue supply component to supply glue to the glue application mechanism; Control the action of the glue application mechanism to make the glue application roller roll against the surface of the product to be glued and apply glue to the surface of the product.

[0046] The following is in conjunction with the appendix Figure 1-17 This application will be described in further detail.
[0047] This application discloses an adhesive application mechanism. (Refer to...) Figure 7 and Figure 8 As shown, the glue application mechanism is used to apply glue to the surface of the product to be glued. It includes a glue application head 5 and a glue dispensing component 8. The glue dispensing component 8 is used to supply glue to the glue application head 5, and the glue application head 5 is used to apply the glue to the surface of the product to complete the glue application.
[0048] In this embodiment, as Figure 4 , Figures 7-10As shown, the coating head 5 includes at least: a transverse movement device 52, a shaft frame 55, a push-pull device 513, and a material detection element 810. The transverse movement device 52 is fixedly installed and connected to a mounting plate 53, which drives the mounting plate 53 to move laterally. The shaft frame 55 is hinged to the mounting plate 53, allowing the shaft frame 55 to swing around the mounting plate 53, such as swinging up and down, left and right, or back and forth. A coating roller is rotatably mounted on the shaft frame 55, and the swing of the shaft frame 55 around the mounting plate 53 drives the coating roller to swing synchronously. The push-pull device 513 is hinged to the mounting plate 53, and its push-pull movable end is connected to the shaft frame 55, which drives the shaft frame 55 to swing around the mounting plate 53. The swing of the shaft frame 55 allows the coating roller to contact the product to be coated, and then the transverse movement device 52 or the transverse movement device 513... The device 52 and the push-pull device 513 work together to drive the glue-applying roller to roll against the surface of the product to be glued, thus applying glue to the product surface. The material detection element 810 is used to detect whether there is a product to be glued in the swing direction of the glue-applying roller. When the material detection element 810 detects a product to be glued, it can control the push-pull device 513 to swing the shaft frame 55 towards the product so that the glue-applying roller contacts the product to be glued. Then, the transverse device 52 or the transverse device 52 and the push-pull device 513 work together to drive the glue-applying roller to roll against the surface of the product to be glued, thus applying glue to the product surface. During the glue application process, the product to be glued remains fixed throughout. When the material detection element 810 does not detect a product, it can control the push-pull device 513 to swing the shaft frame 55 back to its original position based on the detection signal.
[0049] by Figure 4 , Figures 7-10 For example, when the product to be coated is placed under the coating roller, the shaft 55 can swing up and down around the mounting plate 53 to adjust the height of the coating roller. The downward swing of the shaft 55 can make the coating roller contact the product to be coated. Then, the transverse movement device 52 drives the coating roller to roll along the surface of the product to be coated and apply glue to the product surface. At this time, the material detection element 810 is used to detect whether there is a product to be coated under the coating roller. When the material detection element 810 detects a product to be coated, the shaft 55 swings down to make the coating roller contact the product to be coated and roll along the surface of the product to be coated and apply glue to the product surface.
[0050] In this embodiment, the transverse movement device 52 is a linear motor, a pneumatic cylinder, or a hydraulic cylinder. The linear motor, pneumatic cylinder, or hydraulic cylinder can drive the coating roller to move smoothly with high precision. The coating roller will not shake during the movement, ensuring the uniformity of the adhesive film thickness.
[0051] In this embodiment, further, such as Figure 4 and Figure 10As shown, the coating roller includes a cylindrical shaft 58, a roller 56 sleeved on the cylindrical shaft 58, and a cloth sleeve 57 tightly fitted outside the roller 56. The cloth sleeve 57 is used to absorb glue and apply glue to the product surface. The cylindrical shaft 58, roller 56, and cloth sleeve 57 are coaxially arranged and rotate synchronously. The cylindrical shaft 58 is rotatably mounted on the shaft frame 55, and the cylindrical shaft 58 can move axially to separate from the shaft frame 55.
[0052] Furthermore, such as Figures 14-17 As shown, the outer circumference of the roller 56 and the cloth sleeve 57 is recessed inward to form an annular groove 300. The glue-applying roller designed in this way can effectively and evenly apply glue to the arc-shaped area of the midsole surface.
[0053] In this embodiment, as Figure 9 and Figure 10 As shown, the shaft bracket 55 is equipped with a shaft seat 59, and the cylindrical shaft 58 passes through the shaft seat 59 and is rotatably connected to the shaft seat 59. One end of the cylindrical shaft 58 extending out of the shaft seat 59 is connected to a shaft locking device 2. Preferably, the shaft locking device 2 and the cylindrical shaft 58 are detachably and fixedly connected. Of course, in addition to the shaft locking device 2 and the cylindrical shaft 58 being detachably and fixedly connected, the shaft locking device 2 and the cylindrical shaft 58 can also be fixedly connected, not detachable, or rotatably connected.
[0054] In this embodiment, the limiting element is a limiting plate 510, which is movably connected to the shaft frame 55. This includes the shaft frame 55 being detachably and fixedly installed or slidably installed with the limiting plate 510. The limiting plate 510 can move relative to the shaft frame 55 from position one to position two, where positions one and two do not coincide. The shaft locking device 2 abuts against the limiting plate 510 at position one. The limiting plate 510 at position one can prevent the shaft locking device 2 from moving axially along the cylindrical shaft 58, causing the cylindrical shaft 58 to leave the shaft frame 55. Figure 9 As shown, the presence of the limiting plate 510 prevents the locking device 2 from moving axially along the cylindrical shaft 58. When it is necessary to replace the coating roller, such as replacing one or more components of the cylindrical shaft 58, roller 56, and cloth sleeve 57, first move the limiting plate 510 from position one to position two, that is, remove the limiting plate 510 or slide it away from position one, and then move the locking device 2 axially along the cylindrical shaft 58 to remove the cylindrical shaft 58 from the shaft holder 55 to replace the coating roller.
[0055] In this embodiment, when the limiting plate 510 is slidably connected to the shaft bracket 55, such as Figure 9 As shown, the limiting plate 510 is provided with an elongated hole 512 and an adjusting element 511. The adjusting element 511 passes through the elongated hole 512 and is inserted into the shaft bracket 55. Operating the adjusting element 511 can press and fix the limiting plate 510 on the shaft bracket 55, preventing it from sliding. Conversely, operating the adjusting element 511 can also loosen the pressure on the limiting plate 510, allowing it to slide on the shaft bracket 55. Common adjusting elements 511 include screws and bolts.
[0056] In this embodiment, as Figure 9 As shown, the limiting plate 510 is a U-shaped plate, and the shaft locking device 2 includes a shaft cylinder 22 and limiting rings 21 and knobs 23 installed at both ends of the shaft cylinder 22. A part of the limiting rings 21 is located inside the U-shaped plate and is blocked and limited by the U-shaped plate. The shaft cylinder 22 is inserted into one end of the cylinder shaft 58. The knobs 23 are designed to facilitate turning the shaft locking device 2, which is suitable for situations where the shaft cylinder 22 and the cylinder shaft 58 are threadedly connected.
[0057] Of course, in other embodiments, the limiting element can also be a limiting post 200, such as... Figures 14-17 As shown, the limiting post 200 is movably connected to the shaft bracket 55. The limiting post 200 can move relative to the shaft bracket 55 from position one to position two. Position one and position two do not coincide. The outer circumferential surface of the shaft cylinder 22 is constructed with a limiting hole 105. When the limiting post 200 descends and inserts into the limiting hole 105 to position one, it can prevent the shaft lock 2 from moving axially. Conversely, when the limiting post 200 moves upward and leaves the limiting hole 105 to position two, the shaft lock 2 can move axially.
[0058] Specifically, the limiting post 200 includes a post sleeve 101 fixedly connected to the shaft bracket 55. A movable post 100 is axially slidably installed in the post sleeve 101, and the movable post 100 can rotate within the post sleeve 101. The upper end face of the post sleeve 101 has a groove 102, and a locking block 103 is provided in the groove 102. The locking block 103 is fixedly connected to the movable post 100. The movable post 100 and the post sleeve 101 are also connected by an elastic element 104. Pulling the movable post 100 axially upward causes... The elastic element 104 deforms, causing the locking block 103 to disengage from the slot 102 and the lower end of the movable column 100 to disengage from the limiting hole 105. Then, the movable column 100 rotates at a certain angle, causing the locking block 103 and the slot 102 to misalign. The movable column 100 is then released, and the deformed elastic element 104 drives the movable column 100 to move axially downwards, causing the locking block 103 to abut against the upper surface of the sleeve 101. At this point, the movable column 100 is in position one, not affecting the axial movement of the locking device 2. When the movable column 100 continues to rotate, the deformed elastic element 104 drives the movable column 100 to move axially downwards, causing the locking block 103 to fall into the slot 102. Simultaneously, the lower end of the movable column 100 inserts into the limiting hole 105. At this point, the movable column 100 is in position two, preventing the axial movement of the locking device 2.
[0059] Compared to the limiting plate 510, the limiting post 200 is simpler and more convenient to operate in controlling the axial movement of the locking shaft 2, requiring only one hand to pull and rotate the movable post 100.
[0060] Preferably, the elastic element 104 is a spring.
[0061] To facilitate the fixed connection between the column sleeve 101 and the shaft bracket 55, such as Figure 14As shown, the column sleeve 101 and the shaft bracket 55 are fixedly connected by the seat plate 106.
[0062] In this embodiment, further, such as Figure 4 , Figure 7 and Figure 8 As shown, the coating head 5 also has a drive device 514 and a lifting device 51. The drive device 514 is connected to the coating roller drive and is used to drive the coating roller to rotate. This design ensures that the coating roller rotates smoothly, which is beneficial to improving the coating quality. The lifting device 51 is connected to the transverse movement device 52. The lifting device 51 drives the transverse movement device 52 to adjust the height of the coating head 5, so as to meet the coating needs of products of different heights and realize the simultaneous online coating of products of different heights. For example, when the midsole shoe shape is different, the corresponding last 33 height is different, so the lifting device 51 is needed to adjust the height of the coating head 5. Correspondingly, the coating mechanism also has a height detection device for detecting the height of the product to be coated. Common height detection devices include laser sensors and ultrasonic sensors. Of course, in other embodiments, the product height data can also be obtained based on RFID signals (reading the tag information containing the height position data of the product to be coated before coating) to control the lifting device 51 to adjust the height of the coating head 5.
[0063] In this embodiment, as Figure 4 , Figures 7-10 As shown, the glue dispensing assembly 8 has at least a glue dispensing plate, which is located above the coating roller and connected to the shaft frame 55. The glue dispensing plate is provided with a glue dispensing hole 86, through which glue is supplied to the outer circumferential surface of the coating roller.
[0064] In this embodiment, further, the glue dispensing plate is provided with a glue channel 85, one end of which extends to the outer wall surface of the glue dispensing plate to allow glue to be injected into the glue channel 85, such as... Figure 7 As shown, there are multiple glue outlet holes 86, which are spaced apart along the axial direction of the glue coating roller, and the multiple glue outlet holes 86 are connected to the glue distribution channel 85.
[0065] This design utilizes multiple glue outlets 86 to evenly deliver glue to all parts of the outer circumference of the coating roller, improving the glue coating quality of the product. It is very suitable for coating rollers with a large axial length. At the same time, to facilitate the supply of glue to the multiple glue outlets 86, a glue distribution channel 85 is set to connect the multiple glue outlets 86. With this design, it is only necessary to inject glue into the glue distribution channel 85, and the glue will flow into the multiple glue outlets 86 by itself within the glue distribution channel 85.
[0066] Preferred, such as Figure 7As shown, the glue dispensing plate includes a first plate 81 and a second plate 84 that are sealed and fixedly connected. Preferably, the first plate 81 and the second plate 84 are detachably and fixedly connected to facilitate subsequent cleaning and maintenance of the glue application channel 85 and the glue dispensing hole 86. One specific form of the detachable and fixed connection of the first plate 81 and the second plate 84 is as follows: Figure 7 , Figures 11-13 As shown, a fixing element 88 is provided through the second plate 84. After passing through the second plate 84, the fixing element 88 is detachably and fixedly connected to the first plate 81. The first plate 81 and the second plate 84 are locked and sealed and fixedly connected by the fixing element 88. Common fixing elements 88 include screws or bolts.
[0067] In this embodiment, the adhesive channel 85 and the adhesive outlet 86 are located in plate one 81 and / or plate two 84. This design significantly reduces the processing cost and difficulty of the adhesive channel 85 compared to a single piece of adhesive outlet plate. For example... Figure 12 and Figure 13 As shown, the adhesive channel 85 is positioned on the side of plate two 84 facing plate one 81. This seals the adhesive channel 85 after plate one 81 and plate two 84 are sealed and fixedly connected. Alternatively, in other embodiments, the adhesive channel 85 can be positioned on the side of plate one 81 facing plate two 84, or on both the side of plate one 81 facing plate two 84 and the side of plate two 84 facing plate one 81. The adhesive outlet 86 can be positioned as follows... Figure 12 and Figure 13 It can be set inside the second board 84 as shown, or it can be set inside the first board 81, or both the first board 81 and the second board 84 are provided with glue outlet holes 86.
[0068] In this embodiment, as Figure 12 and Figure 13 As shown, the lower end of the second plate 84 is provided with a glue outlet slope 87, the lower end of the glue outlet hole 86 is located on the glue outlet slope 87, and the upper end of the glue outlet hole 86 is connected to the glue distribution channel 85. The setting of the glue outlet slope 87 facilitates the glue to be discharged quickly from the glue outlet hole 86, and avoids the glue discharge from the glue outlet hole 86 being obstructed due to the influence of the glue coating roller.
[0069] In this embodiment, further, such as Figures 7-13As shown, the glue dispensing assembly 8 also has a pair of baffles 89 located at both ends of the coating roller along its axial direction. The baffles 89 are connected to the glue dispensing plate. The lower end of the baffles 89 is provided with an arc surface 80 that fits against the outer circumferential surface of the coating roller. The lower end of the glue dispensing plate is separated from the outer circumferential surface of the coating roller, so that the pair of baffles 89 and the glue dispensing plate together define a glue storage space 10 for temporary storage of glue above the coating roller. The glue dispensing hole 86 is connected to the glue storage space 10. The glue flowing out of the glue dispensing hole 86 is temporarily stored in the glue storage space 10. Then, the coating roller rotates and picks up the glue in the glue storage space 10. This method of supplying glue to the coating roller makes the glue layer on the outer circumferential surface of the rotating coating roller more uniform and consistent, which helps to improve the coating quality and also facilitates the subsequent adjustment of the glue layer thickness.
[0070] In this embodiment, as Figure 7 and Figure 11 As shown, the glue dispensing plate is equipped with a pipe connector 82, which is used to connect with an external pipe for conveying glue. The glue enters the glue dispensing hole 86 inside the glue dispensing plate through the pipe connector 82. When the pipe connector 82 is installed on the plate body 81, as... Figure 11 As shown, a glue supply hole 83 is provided on the side of the first plate 81 facing the second plate 84. After the first plate 81 and the second plate 84 are sealed together, one end of the glue supply hole 83 is connected to the glue distribution channel 85 and the other end is connected to the pipe joint 82.
[0071] In this embodiment, as Figure 4 As shown, the material detection element 810 is mounted and fixed on the dispensing plate. Of course, in other embodiments, the material detection element 810 can also be mounted and fixed on the shaft bracket 55.
[0072] In this embodiment, the dispensing plate is further fixedly connected to the shaft frame 55 in a height-adjustable manner via the position adjustment mechanism 7. The height adjustment of the dispensing plate changes the gap width between the dispensing plate and the outer circumferential surface of the coating roller, thereby adjusting the thickness of the adhesive layer on the outer circumferential surface of the coating roller, and subsequently adjusting the thickness of the adhesive layer coated on the product surface.
[0073] In this embodiment, as Figure 7As shown, the position adjustment mechanism 7 includes a column 71 and stop blocks 72. The column 71 is fixedly installed on the shaft frame 55. A pair of spaced-apart stop blocks 72 are fixedly installed on the column 71 in a height-adjustable manner. For example, the stop blocks 72 are snapped or threaded onto the column 71 so that the stop blocks 72 can move up and down along the column 71 when needed. After moving up and down to the correct position, the stop blocks 72 remain fixedly connected to the column 71. The pair of stop blocks 72 clamps and fixes the glue dispensing plate. By changing the position of the stop blocks 72 on the column 71, the gap width between the glue dispensing plate and the outer circumference of the glue coating roller can be adjusted. This adjustment mechanism has a simple structure, low cost, and reliable and stable adjustment quality. Furthermore, a spring 73 is sleeved on the column 71, and the spring 73 is located below the stop blocks 72. The stop blocks 72 compress the spring 73. This design can prevent the stop blocks 72 from loosening and moving up and down along the column 71 on their own due to vibration of the glue coating mechanism.
[0074] Of course, in other embodiments, the position adjustment mechanism 7 can also be a cylinder, a hydraulic cylinder, or a linear motor.
[0075] During the process of adjusting the gap distance between the dispensing plate and the outer circumferential surface of the coating roller by the position adjustment mechanism 7, the baffle 89 does not move with the dispensing plate. The arc surface 80 at the lower end of the baffle 89 is always in contact with the outer circumferential surface of the coating roller. Therefore, the baffle 89 is slidably and fixedly connected to the dispensing plate relative to the dispensing plate.
[0076] Furthermore, such as Figures 14-17 As shown, the baffle 89 is constructed to extend upward along the circumference of the fabric sleeve 57 in order to better block the glue and prevent the glue from flowing out of the glue storage space 10.
[0077] In other embodiments, plate 84 may also be installed without using fixing element 88, such as... Figure 16 and Figure 17 As shown, the extended baffle 89 has a mounting groove 812. At the bottom of the mounting groove 812, the baffle 89 also has a limiting block 813. The mounting groove 812 is designed to hold the second plate 84. The limiting block 813 prevents the second plate 84 from descending in the mounting groove 812. In addition, the first plate 81 is rotatably mounted with a pressure block 811. After rotating a certain angle, the pressure block 811 can press against the upper surface of the second plate 84 to prevent the second plate 84 from moving upward. With this design, the second plate 84 can be fixedly installed in the mounting groove 812 by the cooperation of the limiting block 813 and the pressure block 811. Rotating the pressure block 811 away from the upper surface of the second plate 84 will allow the second plate 84 to move upward and leave the mounting groove 812.
[0078] As can be seen, compared with fixing the plate 84 by fixing the fixing element 88, the method of fixing the plate 84 by rotating the pressure block 811 ensures that the plate 84 is firmly fixed and has the advantage of being easy to operate.
[0079] Furthermore, such as Figure 14 As shown, a pair of baffles 89 at both ends of the roller 56 are covered with wind shields 814. The wind shields 814 can isolate the glue storage space 10 from the outside world, reduce the impact of external airflow on the glue, weaken the air flow in the glue storage space 10, extend the glue life, and prevent the moisture in the glue in the glue storage space 10 from evaporating too quickly under the wind, causing the glue to solidify too quickly and fail.
[0080] Furthermore, this application also provides an adhesive application device, including an adhesive supply component 9 and an adhesive application mechanism as described above, wherein the adhesive supply component 9 is used to supply adhesive to the adhesive outlet 86 of the adhesive application mechanism. Specifically, as shown... Figure 5 and Figure 6 As shown, the glue supply assembly 9 has a heating base 91 and a glue dispensing pipe 94. The heating base 91 is equipped with a glue tank 92 with a stirring function. The glue tank 92 has a lid 93. The heating base 91 can heat the glue in the glue tank 92. At the same time, the glue tank 92 has a built-in stirring function to stir the glue, ensuring that the glue meets the coating requirements and enabling the coating equipment to apply glue to the product with high quality. The glue dispensing pipe 94 is installed on the lid 93. One end of the glue dispensing pipe 94 extends into the glue tank 92, and the other end is connected to the pipe connector 82. The glue dispensing pipe 94 is equipped with a control valve 54. One end of the glue dispensing pipe 94 extends into the bottom filter cylinder of the glue tank 92. By injecting air into the glue tank 92, the glue in the glue tank 92 is squeezed out through the glue dispensing pipe 94 and sent to the pipe connector 82. After passing through the pipe connector 82, it enters the glue distribution channel 85. The control valve 54 is used to control the opening and closing of the glue dispensing pipe 94.
[0081] In this embodiment, the adhesive coating equipment further includes a clamping mechanism 4, which is used to clamp and fix the product to be coated, thereby realizing automated adhesive coating of the product in a production line and greatly improving the coating efficiency.
[0082] Specifically, such as Figure 2 and Figure 3 As shown, the clamping mechanism 4 has a second lateral movement device 42 and a second material detection element 46. The second lateral movement device 42 is connected to an automatic gripper 43. The second lateral movement device 42 drives the automatic gripper 43 to move laterally to clamp the product to be coated with glue. The second material detection element 46 is used to detect whether there is a product to be coated with glue in the lateral movement direction of the automatic gripper 43. When the second material detection element 46 detects a product to be coated with glue, the second lateral movement device 42 drives the automatic gripper 43 to move towards the product to clamp the product to be coated with glue.
[0083] In this embodiment, when the product to be coated is transferred to the coating equipment via the assembly line, the clamping mechanism 4 clamps and fixes the product for the coating mechanism to apply the adhesive. After the coating is completed, the clamping mechanism 4 releases its grip on the product, and the product is sent away by the assembly line. This achieves automated assembly line coating of products, significantly improving coating efficiency. Figure 1 and Figure 2 For example, multiple material carrier plates 31 are set on the conveyor line 3. A base 32 is fixedly installed on each material carrier plate 31. A last 33 is installed on the base 32. The insole to be coated is fixedly installed on the last 33. The conveyor line 3 drives multiple insoles to move closer to the coating equipment. When the material detection element 2 46 detects a last 33 on its left, the transverse movement device 2 42 drives the automatic gripper 43 to move laterally to the left to clamp the base 32 and fix the insole above the base 32. Then, the glue supply assembly 9 supplies glue to the glue outlet 86 of the coating mechanism. The transverse movement device 1 52 drives the coating head 5 to move laterally to the right to approach the insole. When the material detection element 1 810 detects the insole, the push-pull device 513 pushes the coating roller down to contact the insole. Then, the transverse movement device 1 52 drives the coating head 5 to move laterally to the right at an appropriate speed. The glue roller rolls along the midsole, applying glue to its surface. Once the roller has moved from one end of the midsole's length to the other, the glue application is complete. Simultaneously, the material detection element 810 no longer detects the midsole. Based on this, the push-pull device 513 pulls the glue roller upwards to reset. Then, the lateral movement device 52 moves the roller to the left to reset, while the automatic gripper 43 releases its grip on the base 32. The lateral movement device 42 then moves the automatic gripper 43 to the right to reset. The conveyor line 3 continues to move, carrying the glued midsole to the next station. When the next midsole to be glued arrives at the gluing station and is detected by the material detection element 46, the process repeats. This allows for automated, assembly-line glue application, significantly improving efficiency. The push-pull device 513 adjusts the contact pressure between the glue roller and the product to be glued, ensuring the roller and the last 33 are in an arc-shaped fit, guaranteeing uniform glue application on the midsole surface. If multiple midsoles have different heights, the height of the glue applicator 5 is adjusted by the lifting device 51 according to the midsole height, and then the horizontal movement device 52 is controlled to move the glue applicator 5 laterally to the right and closer to the midsole.
[0084] Commonly used material detection elements include photoelectric switches, laser sensors, and position sensors.
[0085] In this embodiment, specifically, the automatic gripper 43 is a pneumatic gripper, a hydraulic gripper, or an electric gripper, which has a pair of gripping arms 44 for holding products.
[0086] In this embodiment, further, such as Figure 3 As shown, the clamping mechanism 4 also has a buffer 45, which is used to limit the transverse movement device 42 to prevent it from colliding with the conveyor line 3.
[0087] Preferred, such as Figure 2 As shown, the glue coating equipment also includes a glue receiving container 6, which is located directly below the glue coating roller. The glue receiving container 6 is used to collect the glue dripping from the glue coating roller, so as to avoid the glue dripping from the glue coating roller from contaminating other parts of the glue coating equipment and causing trouble for the cleaning operation of the glue coating equipment.
[0088] In this embodiment, furthermore, to facilitate the installation and stable operation of the clamping mechanism 4, the glue application head 5, and the glue receiving container 6, the glue application equipment also includes a frame 1, such as... Figure 1 , Figure 2 As shown, the lifting device 51 is fixedly installed on the frame 1. At this time, the clamping mechanism 4 also has a mounting base 41, which is fixedly connected to the frame 1. The transverse moving device 42 is installed and fixedly mounted on the mounting base 41. Figure 5 As shown, the frame 1 is provided with a conveying space 11 for the conveyor line 3 to pass through, and a cover plate 12 is installed on the outside of the frame 1, such as... Figure 1 and Figure 5 As shown, this design is intended to protect the adhesive application equipment during installation and operation.
[0089] The adhesive application equipment of this application, in addition to being based on Figures 1-13 In addition to the application of adhesive to shoe uppers, midsoles, and outsoles in the footwear industry, the adhesive can also be applied to other fields such as midsole products or products that can be coated with adhesive using an adhesive roller.
[0090] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
