DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0029] The embodiment of the present application discloses a leather gluing device 100 .

[0030] Reference Figure 1-Figure 3 According to the embodiment of the present application, the leather gluing device 100 comprises: a mounting seat 1 and a gluing mechanism 2. The mounting seat 1 is provided with a conveying belt 11. The width direction of the conveying belt 11 can refer to Figure 1 In the left and right directions, a fixed frame 12 is provided on one side of the conveyor belt 11, and a movable frame 13 is provided on the other side of the conveyor belt 11. In some specific embodiments, the fixed frame 12 is located on the right side of the conveyor belt 11, and the movable frame 13 is located on the left side of the conveyor belt 11. The conveyor belt 11 is used to convey leather.

[0031] It should be noted that the conveyor belt 11 is wound around the outer peripheral walls of the active roller and the driven roller, and the motor is connected to the active roller. The motor drives the active roller to drive the conveyor belt 11 to rotate, so that the conveyor belt 11 conveys leather.

[0032] The gluing mechanism 2 is arranged across the conveyor belt 11 and connected between the fixed frame 12 and the movable frame 13. The gluing mechanism 2 includes a plurality of nozzles 21, and the plurality of nozzles 21 are arranged in sequence along the width direction of the conveyor belt 11. Specifically, the leftmost nozzle 21 among the plurality of nozzles 21 is connected to the movable frame 13, and the rightmost nozzle 21 among the plurality of nozzles 21 is connected to the fixed frame 12. Each nozzle 21 is suitable for being arranged relative to the leather. By moving the movable frame 13 close to or away from the fixed frame 12, any two adjacent nozzles 21 are made to approach or move away from each other to adjust the gluing range of the gluing mechanism 2.

[0033] Specifically, when the gluing range of the gluing mechanism 2 is larger than the width of the leather, the operator drives the movable frame 13 to move close to the fixed frame 12, so that the movable frame 13 drives the multiple nozzles 21 to move close to the fixed frame 12. In the process of the multiple nozzles 21 moving close to the fixed frame 12, the movable frame 13 first drives the nozzle 21 connected and coordinated with the movable frame 13 to move close to the adjacent nozzle head 21. When the nozzle 21 connected and coordinated with the movable frame 13 stops with the adjacent nozzle head 21, the nozzle 21 connected and coordinated with the movable frame 13 drives the adjacent nozzle head 21 to move close to the fixed frame 12. The nozzle head 21 close to the movable frame 13 of any two adjacent nozzle heads 21 moves close to the nozzle head 21 away from the movable frame 13, and drives the nozzle head 21 away from the movable frame 13 to move close to the fixed frame 12. That is to say, along the direction from left to right, the movable frame 13 drives the multiple nozzles 21 to move close to the fixed frame 12 in turn, thereby achieving the technical effect of reducing the gluing range of the gluing mechanism 2.

[0034] When the gluing range of the gluing mechanism 2 is smaller than the width of the leather, the operator drives the movable frame 13 to move away from the fixed frame 12, so that the movable frame 13 drives the multiple nozzles 21 to move away from the fixed frame 12. In the process of the multiple nozzles 21 moving away from the fixed frame 12, the movable frame 13 first drives the nozzle 21 connected and cooperated with the movable frame 13 to move away from the adjacent nozzle head 21. When the interval distance between the nozzle 21 connected and cooperated with the movable frame 13 and the adjacent nozzle head 21 is equal to the preset distance, the nozzle 21 connected and cooperated with the movable frame 13 drives the adjacent nozzle head 21 to move away from the fixed frame 12, and the nozzle head 21 close to the movable frame 13 of any two adjacent nozzle heads 21 moves away from the adjacent nozzle head 21, and drives the adjacent nozzle head 21 to move away from the fixed frame 12. That is to say, along the direction from left to right, the movable frame 13 drives the multiple nozzles 21 to move away from the fixed frame 12 in turn, thereby achieving the technical effect of increasing the gluing range of the gluing mechanism 2.

[0035] Furthermore, the movable frame 13 may only drive part of the plurality of nozzles 21 to move closer to the fixed frame 12 to adjust the gluing range of the gluing mechanism 2 .

[0036] Thus, by driving the movable frame 13 to move closer to or away from the fixed frame 12, the movable frame 13 drives the multiple nozzles 21 to move closer to or away from the fixed frame 12, and drives any two adjacent nozzles 21 to move closer to or away from each other, so that the gluing range of the gluing mechanism 2 matches the leathers of different widths. Compared with the prior art, the leather gluing device 100 does not need to replace nozzles 21 of different widths to apply glue to leathers of different widths, thereby improving the gluing efficiency of the leather gluing device 100.

[0037] Reference Figure 3 and Figure 4 In some embodiments of the present application, a guide rod 211 is provided between any two adjacent nozzles 21 , the guide rod 211 is extended along the width direction of the conveyor belt 11 , the nozzle 21 is slidably provided on the guide rod 211 , and the guide rod 211 is used to guide the movement direction of the corresponding two nozzles 21 .

[0038] Specifically, when the movable frame 13 drives multiple nozzles 21 to move closer to or away from the fixed frame 12, the guide rod 211 can guide the nozzle 21, thereby preventing the nozzle 21 from deviating from the preset motion trajectory and causing the nozzle 21 to be unable to face the leather, thereby improving the working reliability of the leather gluing equipment 100.

[0039] Furthermore, when the movable frame 13 drives the nozzle head 21 close to the movable frame 13 of the two adjacent nozzles 21 to move away from the fixed frame 12, the nozzle head 21 close to the movable frame 13 slides along the guide rod 211 to the left end portion of the guide rod 211 and stops with the left end portion of the guide rod 211, and then the nozzle head 21 close to the movable frame 13 drives the guide rod 211 to move away from the fixed frame 12, and the right end portion of the guide rod 211 drives the nozzle head 21 close to the fixed frame 12 of the two adjacent nozzles 21 to move away from the fixed frame 12, thereby achieving the technical effect that the movable frame 13 drives multiple nozzles 21 to move away from the fixed frame 12.

[0040] It should be noted that a blocking ring is provided at the end of the guide rod 211 , and the blocking ring is suitable for abutting and limiting against the side wall of the nozzle 21 .

[0041] Furthermore, the end of the guide rod 211 can also be used to push the adjacent spray head 21 to move closer to the fixing frame 12 .

[0042] Reference Figure 3 and Figure 4 In some embodiments of the present application, the outer peripheral wall of the guide rod 211 is sleeved with an elastic member 212, and the elastic member 212 is sandwiched between the two corresponding nozzles 21. The elastic member 212 is used to drive the two corresponding nozzles 21 to move closer to or away from each other. In some specific embodiments, the elastic member 212 can be a spring or the like.

[0043] Specifically, when two adjacent nozzles 21 move toward each other, the elastic member 212 is compressed, and when the two adjacent nozzles 21 move away from each other, the elastic member 212 gradually recovers to its initial length, and the elastic member 212 drives the two adjacent nozzles 21 to move away from each other, thereby achieving the technical effect that the elastic member 212 assists the two adjacent nozzles 21 to move away from each other.

[0044] When two adjacent nozzles 21 move away from each other, the elastic member 212 is stretched, and when the two adjacent nozzles 21 move toward each other, the elastic member 212 gradually recovers to its initial length, and the elastic member 212 drives the two adjacent nozzles 21 to move toward each other, thereby achieving the technical effect that the elastic member 212 assists the two adjacent nozzles 21 to move toward each other.

[0045] Furthermore, the elastic member 212 is also used to drive the nozzle 21 of the two adjacent nozzles 21 close to the movable frame 13 to stop against the left end of the guide rod 211, and to drive the nozzle 21 of the two adjacent nozzles 21 close to the fixed frame 12 to stop against the right end of the guide rod 211.

[0046] Reference Figure 1-Figure 3In some embodiments of the present application, the glue coating mechanism 2 may further include a first driving member 22, a first thickness detecting member 23 and a controller, and the plurality of nozzles 21 are movably arranged on the fixed frame 12 and the movable frame 13, and the plurality of nozzles 21 are suitable for moving along the height direction of the mounting seat 1, and the height direction of the mounting seat 1 may refer to Figure 1 In the up and down direction of the conveyor belt 11, the first driving member 22 is connected and matched with the plurality of nozzles 21. In some specific embodiments, the first driving member 22 can be arranged on the mounting seat 1. In other specific embodiments, the first driving member 22 can be arranged on the fixed frame 12 or the movable frame 13. The first thickness detection member 23 is used to detect the thickness of the leather. Along the conveying direction of the conveyor belt 11, the first thickness detection member 23 is located on the upstream side of the plurality of nozzles 21. The conveying direction of the conveyor belt 11 can refer to Figure 1 In the front-to-back direction, the first thickness detection member 23 is located in front of the plurality of nozzles 21 .

[0047] The first driving member 22 and the first thickness detecting member 23 are both connected to the controller for communication. The controller is used to control the first driving member 22 to drive the multiple nozzles 21 to move closer to or away from the leather according to the detection signal of the first thickness detecting member 23, so as to adjust the spacing distance between the multiple nozzles 21 and the leather.

[0048] Specifically, when the conveyor belt 11 conveys leather, the first thickness detection member 23 detects the thickness of the leather. The controller controls the first driving member 22 to drive the multiple nozzles 21 to move closer to or away from the leather according to the detection signal of the first thickness detection member 23, so as to maintain the spacing distance between the multiple nozzles 21 and the leather at a preset gluing spacing distance, so that the gluing mechanism 2 can apply glue to the surface of leather with different thicknesses. The leather gluing equipment 100 can process leather with different thicknesses, thereby improving the user experience of the leather gluing equipment 100.

[0049] When the thickness of the leather is too large and the spacing between the multiple nozzles 21 and the leather is less than the preset gluing spacing, the first driving member 22 drives the multiple nozzles 21 to move away from the leather to maintain the spacing between the multiple nozzles 21 and the leather at the preset gluing spacing.

[0050] When the thickness of the leather is too small, causing the spacing between the multiple nozzles 21 and the leather to be greater than the preset gluing spacing, the first driving member 22 drives the multiple nozzles 21 to move closer to the leather to maintain the spacing between the multiple nozzles 21 and the leather at the preset gluing spacing.

[0051] In some specific embodiments, the first thickness detection member 23 may be a laser sensor, and the first driving member 22 may be a cylinder, but the present application is not limited thereto. The first thickness detection member 23 may also be an ultrasonic sensor, etc., and the first driving member 22 may also be a hydraulic cylinder, etc.

[0052] It should be noted that the laser sensor calculates the thickness of the leather by calculating the difference between the laser beam emission time and the laser beam return time, and the ultrasonic sensor calculates the thickness of the leather by calculating the difference between the ultrasonic wave emission time and the ultrasonic wave return time.

[0053] In some specific embodiments, the preset glue coating interval distance may be 2 mm, and in other specific embodiments, the preset glue coating interval distance may be 1 mm.

[0054] Reference Figure 1-Figure 3 In some embodiments of the present application, the leather gluing device 100 further includes: a tray 3 and a controller, the tray 3 is used to place leather, a weighing piece is provided in the tray 3, the weighing piece is used to weigh the weight of glue in real time, when the movable frame 13 moves close to the fixed frame 12, the tray 3 is driven to move close to the fixed frame 12, so that the tray 3 and the fixed frame 12 are stopped, the conveyor belt 11 is used to convey the tray 3, the gluing mechanism 2 further includes a second driving member 24, the second driving member 24 is provided on the fixed frame 12, the second driving member 24 is connected and cooperated with the nozzle 21 close to the fixed frame 12 among the multiple nozzles 21, the second driving member 24 is used to drive the corresponding nozzle 21 to drive the multiple nozzles 21 to move along the length direction of the conveyor belt 11, and the length direction of the conveyor belt 11 can be up to Figure 1 The front-to-back direction.

[0055] Multiple nozzles 21, conveyor belt 11 and weighing piece are all connected to the controller for communication. When the leather is opposite to the nozzle 21, the controller controls the conveyor belt 11 to stop conveying the tray 3, and controls the multiple nozzles 21 and the second driving piece 24 to start working. The controller is also used to control the multiple nozzles 21 to stop working according to the detection signal of the weighing piece.

[0056] Specifically, when the conveyor belt 11 conveys the leather to be opposite to the nozzle 21, the controller controls the conveyor belt 11 to stop conveying the tray 3, and then the controller controls the nozzle 21 and the second driving member 24 to start working. The second driving member 24 drives the multiple nozzles 21 to move along the length direction of the conveyor belt 11, and the multiple nozzles 21 apply glue to the leather surface. When the weight of the glue applied on the leather surface is equal to the preset glue weight, the controller controls the multiple nozzles 21 to stop working according to the detection signal of the weighing piece. After the multiple nozzles 21 have completed the gluing, the conveyor belt 11 starts working and conveys the tray 3, thereby avoiding excessive glue applied to the leather surface, and avoiding as much as possible that the glue overflows to the surface of the part where the leather is not attached when the leather is attached to the part, thereby improving the user experience of the leather gluing equipment 100 and reducing the amount of glue used.

[0057] Furthermore, when the conveyor belt 11 stops conveying the tray 3, the movable frame 13 drives the multiple nozzles 21 to move close to the fixed frame 12 to adjust the gluing range of the gluing mechanism 2, and the movable frame 13 simultaneously drives the tray 3 to move close to the fixed frame 12 and stops the tray 3 and the fixed frame 12, so that the multiple nozzles 21 can be opposite to the leather, and the multiple nozzles 21 can apply glue to the surface of the leather, thereby avoiding that when the width of the leather is small, the nozzles 21 close to the fixed frame 12 among the multiple nozzles 21 cannot be opposite to the leather, and the nozzles 21 close to the fixed frame 12 among the multiple nozzles 21 can be avoided from applying glue to the conveyor belt 11, which can reduce the waste of glue.

[0058] In some specific embodiments, the second driving member 24 can drive the plurality of nozzles 21 to move from front to back. In other specific embodiments, the second driving member 24 can drive the plurality of nozzles 21 to move from back to front.

[0059] In some specific embodiments, the weighing element may be a piezoelectric weighing sensor, and the second driving element 24 may be a slide module, but the present application is not limited thereto. The weighing element may also be a capacitive weighing sensor, and the second driving element 24 may also be a cylinder, etc.

[0060] Furthermore, the gluing mechanism 2 also includes a position detection component, which is arranged on the fixed frame 12 and is communicatively connected with the controller. The position detection component is suitable for being opposite to the tray 3 and is used to detect the position of the tray 3.

The camera 6 and the fifth driving member 51 are both communicatively connected to the controller, and the controller is used to control the working state of the fifth driving member 51 according to the detection signal of the camera 6.

[0072] Specifically, when the glue on the leather is unevenly distributed, the controller controls the fifth driving member 51 to drive the scraper 52 to move close to the leather according to the detection signal of the camera 6. The scraper 52 stops at the leather and evenly scrapes the glue on the leather, thereby preventing some areas of the leather from being uncoated with glue, and preventing the areas of the leather that are not coated with glue from being unable to adhere to the parts, thereby improving the working reliability of the leather gluing equipment 100.

[0073] When the glue on the leather is evenly distributed, the controller controls the fifth driving member 51 to drive the scraper 52 to move away from the leather according to the detection signal of the camera 6 .

[0079] Specifically, when the conveyor belt 11 conveys the tray 3 to the scraping mechanism 5, the sixth driving member 71 drives the second blocking plate 72 to move close to the conveyor belt 11, and the second blocking plate 72 blocks the tray 3. Then the seventh driving member 54 drives the fifth driving member 51 to drive the scraper 52 to move along the length direction of the conveyor belt 11, so that the scraper 52 can evenly scrape the glue on the leather surface, thereby preventing the movement inertia of the conveyor belt 11 from continuing to drive the tray 3 to move, and preventing part of the leather from passing over the scraping mechanism 5, resulting in the glue on the leather surface cannot be evenly scraped, thereby improving the working reliability of the leather gluing equipment 100. After the scraping mechanism 5 completes scraping the glue, the sixth driving member 71 drives the second blocking plate 72 to move away from the conveyor belt 11.
