Description

Technical Field

[0001] The invention relates to a shoe-making device, in particular to a full-automatic polyurethane pouring production line. Background Art

[0002] The polyurethane pouring assembly line is an assembly line for making shoes. This assembly line is annular, and the mold seat carrying the shoe mold moves along the annular track. The shoe mold completes the corresponding work in each process on the assembly line in sequence. The existing general shoe mold is an upper mold and a lower mold structure, and the processing assembly line molding adapted to this shoe mold is relatively simple. For example, the applicant applied for an invention patent named "a shoe sole making device" on May 28, 2014. The equipment required to be protected by the patent includes an annular conveyor belt and a shoe mold on the conveyor belt. The shoe mold has an upper mold and a lower mold hinged together. The upper mold is provided with a handle. The conveyor belt is provided with a shoe mold opening device, a shoe mold pouring device and a shoe mold closing device in sequence. The shoe mold opening device and the shoe mold closing device have a wrench that can move left and right. The wrench is connected to the motor transmission to realize rotation. The shoe mold opening device and the shoe mold closing device have a detection mechanism. When the shoe mold passes through the shoe mold opening device or the shoe mold closing device, the corresponding wrench tracks the movement of the shoe mold, and the upper mold is opened or closed by acting on the handle of the upper mold. This shoe sole production equipment can automatically open, pour and close the shoe mold, so that the production of the shoe sole is replaced by machinery instead of manual labor, reducing the production cost of the enterprise and providing production benefits. However, in order to manufacture double-layer soles (with outsole and midsole, with two colors), the existing shoe mold is upgraded, such as Figure 6 As shown, the improved shoe mold has a main mold, a transverse mold and a longitudinal mold. The main mold is hinged with the longitudinal mold. The longitudinal mold can be rotated longitudinally to form a first mold cavity with the main mold. The first mold cavity is used for molding the outsole (i.e., the first color sole). After the molding of the outsole is completed, the longitudinal mold is opened, and polyurethane of another color is poured on the outsole. Then the transverse mold is rotated horizontally, and the shoe last on the transverse mold comes to the top of the main mold. In this way, the shoe last, the transverse mold and the main mold form a second mold cavity, and the second mold cavity forms the midsole of the sole (i.e., the second color sole), thereby completing the molding of the two-color sole. Obviously, the existing sole manufacturing equipment cannot complete the automation of the molding of the double-layer sole, and the market urgently needs a device that can automatically complete the molding of the double-layer sole.

[0021] As Figure 6 shown, as described in the background art, the existing mold includes a main mold A, a horizontal mold B, and a vertical mold C. The main mold A is hinged to the vertical mold C. The vertical mold C has a vertical wrench C1 and a lock C2. By manually holding the vertical wrench C1 and pulling it downwards, the vertical mold C can be vertically flipped and joined with the main mold A. At the same time, the lock C2 is buckled on the main mold A, thereby realizing vertical mold closing; the horizontal mold B is hinged to one side of the main mold A. The horizontal mold B has a horizontal wrench B2. By manually holding the horizontal wrench B2 and pulling it to one side, the horizontal mold B can be horizontally flipped and joined with the main mold A. Then, the locking part A3 on the main mold A is locked to the horizontal mold B by the shoe mold locking device 11 (as Figure 4 shown, the shoe mold locking device 11 has a contact wheel 110. When the mold moves, the locking part A3 on the main mold A will touch the contact wheel 110, so that the locking part A3 can rotate and lock the horizontal mold B, which is the prior art), thereby realizing horizontal mold closing.

[0022] The above is the manual production method. In order to achieve automation, the present invention innovatively provides a full-automatic intelligent polyurethane casting production line. As Figure 1As shown in the figure, the fully automatic intelligent polyurethane casting production line includes a ring conveyor 1, a mold base placed on the ring conveyor 1 for placing molds, and a shoe mold locking device 11. The molds mentioned above are placed on the mold base and move in a cycle together with the mold base. The ring conveyor 1 has a working station section and a drying section: beside the working station section of the ring conveyor 1, there are installed a mold release agent spraying device 2 for spraying mold release agent into the mold, a longitudinal mold opening device 8 for opening the mold longitudinally, a polyurethane casting device 3 for casting polyurethane into the mold, a longitudinal mold closing device 4 for closing the mold longitudinally, a transverse mold closing device 5 for closing the mold transversely, and a transverse mold opening device 7 for opening the mold transversely. And the drying section of the ring conveyor 1 is located in the drying tunnel 6; the mold release agent spraying device 2 includes a spraying head, the longitudinal mold opening device 8 includes a longitudinal mold opening member 812, the polyurethane casting device 3 includes a polyurethane casting head, the longitudinal mold closing device 4 includes a longitudinal mold closing member, the transverse mold closing device 5 includes a transverse mold closing member, and the transverse mold opening device 7 includes a transverse mold opening member 74.

[0023] The whole machine production process is as follows: 1. Clean the production residues and other impurities on the mold surface; 2. The mold release agent spraying device 2 sprays mold release agent on the concave surface of the mold; 3. The polyurethane casting device 3 casts the polyurethane mixture with set color and density into the main mold A of the mold; 4. The longitudinal mold closing device 4 closes the longitudinal mold C of the mold and locks it; 5. The mold enters the drying tunnel 6 for heating and shaping; 6. After the outsole is formed (the first layer), the longitudinal mold opening device 8 opens the longitudinal mold C of the mold; 7. The polyurethane casting device 3 casts the polyurethane mixture with set color and density into the main mold A again (cast on the outsole); 8. The transverse mold closing device 5 closes the transverse mold B of the mold and locks it through the shoe mold locking device 11; 9. The mold enters the drying tunnel 6 again for heating and shaping; 10. After the midsole is formed (the second layer), the transverse mold opening device 7 opens the transverse mold B of the mold; 11. Take out the finished connected-sole shoes with foam shaping. The mold completes the production after circulating twice on the ring conveyor 1.

[0024] The above is the working process of the whole machine. The following specifically introduces the structure and principle of each station device.

[0025] As Figure 2As described above, this mold release agent spraying device 2 includes a spraying machine base 21. A spraying transverse guide rail 23 is installed on the spraying machine base 21. A spraying transverse sliding seat 22 is slidably arranged on the spraying transverse guide rail 23. The spraying transverse sliding seat 22 is in transmission connection with a spraying transverse power source for driving the movement of the spraying transverse sliding seat 22. Driven by the spraying transverse power source (not shown), the spraying transverse sliding seat 22 moves horizontally on the spraying transverse guide rail 23. The horizontal movement of the spraying transverse sliding seat 22 follows the moving direction of the mold. In this way, the mold does not need to stop on the annular conveying device 1, and the mold can be sprayed during the moving process.

[0026] A first upright post 24 and a second upright post 211 are installed on the spraying transverse sliding seat 22. A first rotary power source 25 is installed on the first upright post 24. The first rotary power source 25 is in transmission connection with a first rotary arm 26. A second rotary power source 27 is installed on the first rotary arm 25. The second rotary power source 27 is in transmission connection with a support rod 28. A first spray head 210 is connected to the support rod 28. Driven by the first rotary power source 25, the first rotary arm 26 rotates. Driven by the second rotary power source 27, the support rod 28 rotates. In this way, the first spray head 210 can rotate in two dimensions. As Figure 6 shown, the first spray head 210 is to spray the main mold A of the mold. The rotation of the first rotary arm 26 can make the spraying range of the first spray head 210 cover the inner bottom surface A1 of the mold cavity of the main mold A, and the rotation of the support rod 28 can make the spraying range of the first spray head 210 cover the left and right side surfaces A2 of the mold cavity of the main mold A.

[0027] Two spraying units are installed on the second upright post 211, one on the left and one on the right. Each spraying unit includes a support plate 215, a third rotary power source 216, a fourth rotary power source 218, and a second spray head 219. The third rotary power source 216 is installed on the support plate 215 and is in transmission connection with a second rotary arm 217. The fourth rotary power source 218 is installed on the second rotary arm 217 and is in transmission connection with the second spray head 219 (the transmission connection is realized through a synchronous pulley and synchronous belt structure). Driven by the third rotary power source 216, the second rotary arm 217 rotates. Driven by the fourth rotary power source 218, the second spray head 219 rotates. In this way, the second spray head 219 can also rotate in two dimensions. As Figure 6 shown, the second spray head 219 is to spray the transverse mold B of the mold. The rotation of the second rotary arm 217 can make the second spray head 219 face the inner side surface B1 of the mold cavity of the transverse mold B (the second spray head 219 of one spraying unit faces one inner side surface B1, and the second spray head of the other spraying unit faces the other inner side surface), and the rotation of the second spray head 219 can make its spraying range cover the inner side surface B1 of the mold cavity of the shoe upper mold (the second spray head 219 of one spraying unit covers one inner side surface, and the second spray head 219 of the other spraying unit 219 covers the other inner side surface).

[0028] A spraying longitudinal guide rail 220 is installed on the second vertical column 211. A spraying longitudinal sliding seat 214 is installed on the spraying longitudinal guide rail 220. The spraying longitudinal sliding seat 214 is in transmission connection with a spraying longitudinal power source 213 that drives the movement of the spraying longitudinal sliding seat 214. Driven by the spraying longitudinal power source 213, the spraying longitudinal sliding seat 214 realizes longitudinal movement on the spraying longitudinal guide rail 220. The left and right two spraying units are installed on the spraying longitudinal sliding seat 214 through spraying support plates 215. When the spraying machine is not working, the spraying longitudinal power source 213 drives the spraying longitudinal sliding seat 214 to move back on the spraying longitudinal guide rail 220, so that the two spraying units return to the rear side. Of course, the longitudinal movement of the spraying longitudinal sliding seat 214 can also make the two spraying units move back and forth for spraying.

[0029] As Figure 3 shown, the longitudinal mold opening device 8 includes a mold opening machine base 81 and a longitudinal mold opening member 812 for opening the longitudinal mold C. A mold opening transverse guide rail 82 is installed on the mold opening machine base 81. A mold opening transverse sliding seat 83 is installed on the mold opening transverse guide rail 82. The mold opening transverse sliding seat 83 is in transmission connection with a mold opening transverse power source (not shown) that drives the movement of the mold opening transverse sliding seat 83. Driven by the mold opening transverse power source, the mold opening transverse sliding seat 83 can move on the mold opening transverse guide rail 82, thereby realizing one-dimensional movement; a mold opening vertical seat 84 is installed on the mold opening transverse sliding seat 83. A mold opening vertical guide rail 85 is installed on the mold opening vertical seat 84. A mold opening vertical sliding seat 86 is installed on the mold opening vertical guide rail 85. The mold opening vertical sliding seat 86 is in transmission connection with a mold opening vertical power source 816 that drives the movement of the mold opening vertical sliding seat 86. The mold opening vertical power source 816 is installed on the mold opening vertical seat 84. Driven by the mold opening vertical power source 816, the mold opening vertical sliding seat 86 can move up and down on the mold opening vertical guide rail 85, thereby realizing two-dimensional movement; a mold opening longitudinal sliding seat 88 is installed on the mold opening vertical sliding seat 86. A mold opening longitudinal guide rail 89 is provided on the mold opening longitudinal sliding seat 88. The mold opening longitudinal guide rail 89 is in transmission connection with a mold opening longitudinal power source 87 that drives the movement of the mold opening longitudinal guide rail 89. The mold opening longitudinal power source 87 is installed on the mold opening vertical sliding seat 86. Driven by the mold opening longitudinal power source 87, the mold opening longitudinal guide rail 89 moves on the mold opening longitudinal sliding seat 88, thereby realizing three-dimensional movement; and the longitudinal mold opening member 812 is installed at one end of the mold opening longitudinal guide rail 89. Through the movement in the above three directions, the longitudinal mold opening member 812 can track the movement of the mold and act on the longitudinal handle C1 of the longitudinal mold C to open the longitudinal mold C.

[0030] In order to enable the longitudinal mold opening power source 87 to drive the longitudinal mold opening guide rail 89 to move, in the present invention, connection blocks 810 are connected to both ends of the longitudinal mold opening guide rail 89, a transmission belt 811 is connected between the two connection blocks 810, two tension wheels 814 are installed on the vertical slide 86, a pulley 813 is connected to the output shaft of the longitudinal mold opening power source 87, the pulley 813 is located between the two tension wheels 814, both the pulley 813 and the tension wheels 814 act on the transmission belt 811, and the longitudinal mold opening member 812 is installed on the connection block 810. The longitudinal mold opening power source 87 drives the pulley 813 to rotate, the pulley 813 drives the tensioned transmission belt 811 to move. Since the transmission belt 811 and the longitudinal mold opening guide rail 89 are connected together through the connection block 810, the longitudinal mold opening guide rail 89 can move on the longitudinal mold opening slide 88. Due to the structure that the longitudinal mold opening member 812 is installed on the longitudinal mold opening guide rail 89 with a relatively long length, the longitudinal mold opening member 812 can extend forward a relatively long distance. At the same time, due to the transmission of the transmission belt 811, the longitudinal mold opening member 812 moves forward and backward faster and runs more stably.

[0031] The longitudinal mold closing device 4 has a longitudinal mold closing member. The longitudinal mold closing device 4 has exactly the same structure as the longitudinal mold opening device 8. The longitudinal mold closing member is the longitudinal mold opening member 812, and the movement of the longitudinal mold closing member 12 is the reverse movement of what the longitudinal mold opening member 12 does. The structure of the longitudinal mold closing device 4 will not be elaborated further.

[0032] As Figure 4 shown, the transverse mold opening device 7 includes a frame 71 and a transverse mold opening member 74. A slide shaft 77 is installed on the frame 71, a slide shaft seat 76 is sleeved on the slide shaft 77, a slide plate 75 is installed on the slide shaft seat 76, the slide plate 75 is in transmission connection with a slide plate power source, a fixing plate 72 is erected on the slide plate 75, a motor 73 is installed on the fixing plate 72, and the transverse mold opening member 74 is in transmission connection with the motor 73. In this way, when the motor 73 rotates, it can drive the transverse mold opening member 74 to rotate. Due to the left and right movement of the slide plate 75, the transverse mold opening member 74 also moves together with the slide plate 75. When the detection mechanism detects that the mold is coming, the transverse mold opening member 74 starts to track the mold. The transverse handle B2 of the transverse mold B is framed by the strip-shaped groove of the transverse mold opening member 74. When the transverse mold opening member 74 rotates counterclockwise, the transverse mold B can be opened. Since the mold is always in a moving state, the transverse mold opening member 74 must also move along. After opening the transverse mold B, the transverse mold opening member 74 returns to its original position and waits for the arrival of the next mold.

[0033] The transverse mold closing device has a transverse mold closing member. The transverse mold closing device has exactly the same structure as the transverse mold opening device. The transverse mold closing member is the transverse mold opening member 12, and the movement of the transverse mold closing member is the reverse movement of what the transverse mold opening member 12 can do. The structure of the transverse mold closing device will not be elaborated further.

[0034] AsFigure 5 As shown, the polyurethane pouring device 3 includes a pouring machine base 31 and a head base 36 for installing a polyurethane pouring head. The polyurethane pouring head is a device for spraying polyurethane (not shown in the figure).

[0035] In order to enable the polyurethane pouring head to move in three dimensions, a pouring transverse guide rail 310 is installed on the pouring machine base 31, and a pouring transverse slide 32 is installed on the pouring transverse guide rail 310. The pouring transverse slide 32 and a pouring transverse power source that drives the pouring transverse slide 32 to move are driven by the pouring transverse power source to move the pouring transverse slide 32 to achieve transverse movement on the pouring transverse guide rail 310. A pouring longitudinal guide rail 320 is installed on the pouring longitudinal guide rail 320, and a pouring longitudinal slide 33 is installed on the pouring longitudinal guide rail 320. The pouring longitudinal slide 33 is connected to the pouring longitudinal power source that drives the pouring longitudinal slide 33 to move, and the pouring longitudinal power source is installed on the pouring transverse slide 32. The pouring longitudinal slide 33 is driven by the pouring longitudinal power source to move the pouring longitudinal slide 33 on the pouring longitudinal guide rail 320. A pouring stand 34 is installed on the pouring longitudinal slide 33, a pouring vertical guide rail 340 is installed on the pouring stand 34, a pouring vertical slide 35 is installed on the pouring vertical guide rail 340, the pouring vertical slide 35 is connected to a pouring vertical power source for driving the pouring vertical slide 35 to move, the pouring vertical power source is installed on the pouring stand 34, and the pouring vertical slide 35 is moved up and down on the pouring vertical guide rail 340 by the drive of the pouring vertical power source; a pouring horizontal guide rail 350 is horizontally installed on the pouring vertical slide 35, a head seat 36 is slidably arranged on the pouring horizontal guide rail 350, the head seat 36 is connected to a pouring horizontal power source for driving the head seat 36 to move, and the head seat 36 is moved horizontally on the pouring horizontal guide rail 350 by the drive of the pouring horizontal power source. Through the above structure, the head seat 36 can realize lateral movement, longitudinal movement, up and down movement, and horizontal movement, wherein the lateral movement has the same direction as the horizontal movement, so the speeds of the two can be superimposed. In this way, the lateral movement speed of the casting lateral slide 32 can be reduced while the overall speed remains unchanged, thereby greatly reducing the requirements for the lateral movement structure.

[0036] Since the polyurethane of the molded midsole is poured on the molded outsole, the liquid polyurethane is in contact with the solid outsole, which may cause the two to be loosely bonded. In order to solve this problem, a pouring preheating device 9 is provided in the front process of the polyurethane pouring device, and the pouring preheating device 9 includes a heat source (which can be various heat sources), and the heat source is located above the annular conveying device. When the mold passes through the pouring preheating device 9, the heat source of the pouring preheating device 9 can slightly melt the surface of the solid outsole, so that the polyurethane poured on the solid outsole can be completely bonded to the solid outsole, so that the connection between the outsole and the midsole after molding is more secure.

[0037] Finally, it is worth mentioning that in order to eliminate the release agent sprayed by the release agent spraying device 2, the present invention is provided with a suction device 10 at the release agent spraying device 2. The suction device 10 includes a suction fan and a suction nozzle, and the suction nozzle faces the spraying position of the release agent spraying device 2. Through the suction of the suction fan, the suction nozzle can suck away the release agent in the air and ensure the cleanliness of the factory environment.
