Description

Technical Field

[0001] This application relates to the field of material conveying, and in particular to a shoe sole side coloring conveying device. Background Technology

[0002] In the shoe manufacturing process, in order to improve the appearance of the shoes, colored pigments are usually sprayed on the sides of the soles to enhance the overall aesthetics.

[0003] Currently, the coloring and spraying of shoe soles on the sides are all automated production lines. Workers place the shoe soles to be colored on the production line, and the conveyor belt on the production line moves the shoe soles forward to the spraying position. Because the shoe sole conveyor line on the production line is long, it occupies a large space in the production workshop, which makes it inconvenient to utilize the space in the production workshop. Utility Model Content

[0004] To address the issue that the long shoe sole conveyor line in the shoe sole coloring production line occupies a large amount of space in the production workshop, which is detrimental to the utilization of space within the production workshop, this application provides a shoe sole side coloring transmission device.

[0005] The technical solution of the shoe sole side coloring transfer device provided in this application is as follows: A shoe sole side coloring conveying device includes a conveyor frame with two conveyor components on it. Each conveyor component has a base, and the base has a workpiece table for placing the shoe sole. A mounting rod is fixed to one end of the top surface of the base. A sliding groove is formed on the top surface of the mounting rod. A moving rod is slidably arranged vertically in the sliding groove. A spring is fixed to the bottom end of the moving rod, and the bottom end of the spring is fixed to the inner bottom surface of the sliding groove. A mounting plate is fixed to the top end of the moving rod. A pressure plate for pressing the shoe sole onto the workpiece table is provided below the mounting plate. A connecting rod is fixed between the pressure plate and the mounting plate. Both ends of the conveyor frame are respectively provided with a conveying mechanism for moving the bases on the two conveyor components.

[0006] By adopting the above technical solution, two layers of conveying components are set on the conveyor frame. The upper conveying component moves the base, and then the worker moves the mounting plate upward to place the shoe sole on the workpiece table. Then the mounting plate is released, and the moving rod moves the mounting plate downward under the elastic force of the spring. The mounting plate moves the pressure plate downward, so that the pressure plate presses the shoe sole onto the workpiece table. The upper conveying component conveys the shoe sole for coloring. When the shoe sole is conveyed to one end of the upper conveying component, the base on the upper conveying component is transferred to the lower conveying component by the handling mechanism at one end of the conveyor frame. The lower conveying component then conveys the base to the other end of the conveyor frame. Then the handling mechanism at the other end of the conveyor frame transfers the base to the upper conveying component, so that the base can be reused. This shortens the length of the shoe sole conveying line, thereby reducing the space occupied by the shoe sole transmission device in the production workshop and facilitating the utilization of space in the production workshop.

[0007] Preferably, each layer of the conveying assembly includes two guide rails mounted on a conveyor frame. The two guide rails are arranged parallel to each other, and each guide rail has a mounting groove on its top surface. A transmission roller 1 and a transmission roller 2 are rotatably mounted between the opposite inner surfaces of the mounting grooves. A conveyor belt 1 is wound around the transmission roller 1 and the transmission roller 2. The base is located on the two transmission belts 1. A connecting shaft is rotatably mounted between the two guide rails. The two ends of the connecting shaft are fixedly connected to the opposite end faces of the two transmission rollers 1, respectively. A motor 1 is provided on the side of one of the guide rails, and the output shaft of the motor 1 is fixedly connected to one end of the transmission roller 1.

[0008] By adopting the above technical solution, starting motor one, the output shaft of motor one drives transmission roller one to rotate, transmission roller one drives connecting shaft to rotate, connecting shaft drives another transmission roller one to rotate, so that the two transmission rollers one rotate simultaneously, so that the two transmission rollers one drive the two conveyor belts one to rotate respectively, so that the conveyor belts one drive the base to move.

[0009] Preferably, a connecting plate is fixed between the two guide rails on the upper layer, and a plurality of cylinders are provided on the bottom surface of the connecting plate. The top end of the cylinder piston rod passes through the bottom surface of the connecting plate, and the cylinder piston rod is slidably connected to the connecting plate in the vertical direction.

[0010] By adopting the above technical solution, when the conveyor belt moves the base to above the connecting plate, the cylinder is activated, and the piston rod of the cylinder moves upward, causing the piston rod to lift the base upward, so that the base is separated from the conveyor belt, making it easier for the workers to place the shoe sole on the workpiece table.

[0011] Preferably, a fixing plate is fixed to the side of one of the upper guide rails, and an infrared sensor for detecting the base is provided on the side of the fixing plate. A controller is provided on the conveyor frame, and the output end of the infrared sensor is electrically connected to the input end of the controller. The output end of the controller is electrically connected to the control end of the cylinder to control the opening and closing of the cylinder in response to the detection signal of the infrared sensor.

[0012] By adopting the above technical solution, when the base moves above the connecting plate, the infrared sensor detects the base and transmits the detected signal to the controller. The controller controls the cylinder to start, causing the cylinder piston rod to push the base upward, thereby causing the base to detach from the conveyor belt and stop moving, thus making it easier for workers to place the shoe sole on the workpiece table.

[0013] Preferably, the conveying mechanism includes mounting frames disposed at both ends of the conveyor frame. A movable seat is slidably disposed vertically within the mounting frame. Grooves are provided on both sides of the top surface of the movable seat. A transmission roller three and a transmission roller four are rotatably mounted between the opposite inner surfaces of the grooves. A conveyor belt two is wound around the transmission roller three and the transmission roller four. A transmission shaft is rotatably mounted between the opposite inner surfaces of the movable seat. The two end faces of the transmission shaft are respectively fixedly connected to the opposite end faces of the two transmission roller threes. A motor two is disposed on the side of the movable seat. The output shaft of the motor two is fixedly connected to one end of one of the transmission roller threes. A driving component for driving the movable seat to move vertically is disposed on the mounting frame.

[0014] By adopting the above technical solution, when the upper conveyor belt 1 transports the base to the end of the conveyor frame, the drive unit is activated. The drive unit drives the movable seat to move upward, so that the top surface of the movable seat is coplanar with the top surface of the upper guide rail. The motor 2 on the movable seat is activated. The output shaft of the motor 2 drives the transmission roller 3 to rotate. The transmission roller 3 drives the transmission shaft to rotate. The transmission shaft drives another transmission roller 3 to rotate, so that the two transmission rollers 3 rotate simultaneously. The transmission roller 3 drives the conveyor belt 2 to rotate, so that when the conveyor belt 1 transports the base to the conveyor belt 2, the conveyor belt 2 moves the base onto the movable seat. Then the drive unit is activated again, so that the drive unit drives the movable seat to move downward, so that the movable seat moves the base downward, so that the base moves to a position on the lower conveyor belt. Then the motor 2 is activated again, so that the output shaft of the motor 2 drives the transmission roller 3 to rotate in the opposite direction, so that the transmission roller 3 drives the conveyor belt 2 to rotate in the opposite direction, so that the conveyor belt 2 transports the base onto the lower conveyor belt 1, so that the conveyor belt 1 transports the base to the other end of the conveyor frame, so that the conveying mechanism on the other side of the conveyor frame transports the base onto the upper conveyor belt 1, thus facilitating the recycling of the base.

[0015] Preferably, two side plates are fixed to one side of the inner top surface of the mounting frame, and two side plates are fixed to one end of the inner bottom surface of the mounting frame. The driving component includes a timing pulley rotatably disposed between the two side plates and a timing pulley rotatably mounted between the two side plates. A timing belt is wound around the timing pulleys. A motor is disposed on the side of one of the side plates. The output shaft of the motor is fixedly connected to one end of the timing pulley. A moving block is fixed to the side of the moving seat. A fixed block is disposed on one side of the moving block. The timing belt passes between the moving block and the fixed block. The fixed block is fixedly connected to the moving block by bolts.

[0016] By adopting the above technical solution, the fixed block presses the timing belt onto the moving block, and then the bolts fix the fixed block and the moving block together, so that the fixed block presses the timing belt onto the moving block. Then, the motor three is started, so that the output shaft of the motor three drives the timing pulley two to rotate, and the timing pulley two drives the timing belt to rotate, so that the timing belt drives the moving block to move vertically, and then the moving block drives the moving seat to move vertically.

[0017] Preferably, two limiting blocks are fixed on the side of the top surface of the movable seat away from the conveyor frame.

[0018] By adopting the above technical solution, a limiting block is set on the top surface of the movable seat away from the conveyor frame. When the base moves onto the movable seat, the limiting block limits the base, thereby reducing the possibility of the base moving out of the movable seat.

[0019] Preferably, two guide blocks are fixed on both sides of the movable seat, and the sides of the two guide blocks that are far apart from each other are respectively in contact with the opposite inner sides of the mounting frame.

[0020] By adopting the above technical solution, guide blocks are set on both sides of the movable seat, so that the guide blocks fit against the inner side of the mounting frame, thereby making the movable seat more stable when moving vertically.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. Two layers of conveying components are set on the conveyor frame. The upper conveyor component moves the base, and then the worker moves the mounting plate upward to place the shoe sole on the workpiece table. Then the mounting plate is released, and the moving rod moves the mounting plate downward under the elastic force of the spring. The mounting plate moves the pressure plate downward, so that the pressure plate presses the shoe sole onto the workpiece table. The upper conveyor component conveys the shoe sole for coloring. When the shoe sole is conveyed to one end of the upper conveyor component, the base on the upper conveyor component is transferred to the lower conveyor component by the handling mechanism at one end of the conveyor frame. The lower conveyor component then conveys the base to the other end of the conveyor frame. Then the handling mechanism at the other end of the conveyor frame transfers the base to the upper conveyor component, so that the base can be reused. This shortens the length of the shoe sole conveying line, thereby reducing the space occupied by the shoe sole transmission device in the production workshop and facilitating the use of space in the production workshop. 2. When the base moves above the connecting plate, the infrared sensor detects the base and transmits the detected signal to the controller. The controller controls the cylinder to start, causing the cylinder piston rod to push the base upward, thereby causing the base to disengage from the conveyor belt and stop moving, thus making it easier for the worker to place the shoe sole on the workpiece table. 3. Press the timing belt onto the moving block using the fixed block, then use bolts to fix the fixed block and the moving block together, so that the fixed block presses the timing belt onto the moving block. Then start motor three, so that the output shaft of motor three drives timing pulley two to rotate, timing pulley two drives timing belt to rotate, so that timing belt drives the moving block to move vertically, and then the moving block drives the moving seat to move vertically.

[0034] The implementation principle of the shoe sole side coloring transmission device in this application embodiment is as follows: start the motor 27 located on the upper layer of the conveyor frame 1, the output shaft of the motor 27 drives the transmission roller 23 to rotate, the transmission roller 23 drives the connecting shaft 26 to rotate, the connecting shaft 26 drives another transmission roller 23 to rotate, so that the two transmission rollers 23 rotate at the same time, and the two transmission rollers 23 respectively drive the two conveyor belts 25 to rotate, thereby causing the conveyor belts 25 to move the base 3. When the base 3 moves above the connecting plate 4, the infrared sensor 42 detects the signal of the base 3 and transmits the signal to the controller 43. The controller 43 controls the cylinder 41 to start, causing the piston rod of the cylinder 41 to move upward and lift the base 3, so that the bottom surface of the base 3 is separated from the conveyor belt 25. Then, the worker pulls the mounting plate 36 downward, and the mounting plate 36 drives the pressure plate 37 to move upward, so that the pressure plate 37 is separated from the workpiece table 31. Then, the worker places the shoe sole to be colored on the workpiece table 31, releases the mounting plate 36, and the moving rod 34 moves downward under the elastic force of the spring 35, so that the moving rod 34 drives the mounting plate 36 to move downward, and the mounting plate 36 drives the pressure plate 37 to move downward, so that the pressure plate 37 presses the shoe sole tightly on the workpiece table 31. Then, the cylinder 41 is started again, so that the piston rod of the cylinder 41 moves downward and places the base 3 on the conveyor belt 25, so that the conveyor belt 25 carries the base 3 with the shoe sole forward for processing. After the sole is colored, it will be removed from the workpiece table 31. When the conveyor belt 25 moves the base 3 to the end of the conveyor frame 1, the motor 2 65 is started. The output shaft of the motor 2 65 drives the transmission roller 3 61 to rotate. The transmission roller 3 61 drives the conveyor belt 2 63 to rotate, thereby moving the base 3 onto the moving seat 52. Next, motor 3 75 is started, causing the output shaft of motor 3 75 to drive synchronous belt 74 pulley 2 73 to rotate. Synchronous belt 74 pulley 2 73 drives synchronous belt 74 to rotate, and synchronous belt 74 drives moving seat 52 to move downward, so that moving seat 52 moves to the position of lower conveyor belt 1 25. Then, motor 2 65 is started, causing the output shaft of motor 2 65 to drive transmission roller 3 61 to rotate in the opposite direction. Transmission roller 3 61 drives conveyor belt 2 63 to rotate in the opposite direction, so that conveyor belt 2 63 transports base 3 to lower conveyor belt 1 25, so that conveyor belt 1 25 transports base 3 to the other end of conveyor frame 1, so that the handling mechanism 5 at the other end of conveyor frame 1 transports base 3 to upper conveyor belt 1 25, so that base 3 can be used repeatedly, shortening the length of shoe sole conveying production line, thereby reducing the space occupied by shoe sole conveying device in the production workshop, and thus facilitating the use of space in the production workshop.
