Description

Technical Field

[0001] This application relates to the field of footwear and apparel production equipment, and in particular to a sole pretreatment device. Background Technology

[0002] In the production of shoe soles, some processes use one-piece injection molding, which connects the outsole and midsole to form the sole. Other processes use glue to connect the outsole and midsole to form the sole.

[0003] Before using adhesive to bond the outsole and midsole together, pretreatment of both is generally required. Currently, a shoe sole pretreatment device is disclosed, comprising a first conveyor belt, a chemical tank, and a second conveyor belt arranged sequentially. The first conveyor belt is equipped with a hot air blower. Workers place the shoe soles to be treated onto the first conveyor belt, which then transports them past the hot air blower. The hot air blower heats the soles, causing them to expand and facilitating the absorption of the chemical solution. The first conveyor belt then immerses the soles in the chemical tank for soaking. Afterward, workers remove the soles from the tank and place them onto the second conveyor belt, which then transports them to a dryer for drying. Finally, the second conveyor belt places the dried soles into an irradiation machine for further irradiation, allowing the chemical solution to work effectively, thus cleaning the soles and improving their adhesion.

[0004] Regarding the aforementioned technologies, the inventors believe that after the soles are soaked in chemicals, workers need to remove them from the chemical tank and then place them back on the second conveyor belt, which affects the continuity of the entire sole pretreatment equipment production and reduces the efficiency of sole pretreatment. Summary of the Invention

[0005] To improve the efficiency of sole pretreatment, this application provides a sole pretreatment device.

[0006] This application provides a shoe sole pretreatment device, which adopts the following technical solution:

[0007] A shoe sole pretreatment device includes a first conveyor belt, a chemical tank, and a second conveyor belt arranged sequentially. The first conveyor belt includes a first horizontal section and a first descending section. A hot air blower is installed on the first horizontal section. The chemical tank is equipped with an immersion conveyor belt. The immersion conveyor belt includes a second horizontal section, a second descending section, a third horizontal section, an ascending section, and a fourth horizontal section sequentially along the conveying direction. The second descending section, the third horizontal section, and the ascending section are all located inside the chemical tank. The second horizontal section and the fourth horizontal section are both located on the top side of the chemical tank. Multiple mesh plates are fixedly installed at intervals on the immersion conveyor belt. The first descending section is located above the second horizontal section. A mesh cover is installed on the top side of the immersion conveyor belt. A dryer and an irradiation machine are sequentially installed on the second conveyor belt along the conveying direction.

[0008] By adopting the above technical solution, the shoe sole is placed on the first conveyor belt. After being conveyed on the first conveyor belt, the shoe sole passes through a hot air blower, which heats the shoe sole, causing it to expand. Then, the first conveyor belt sends the shoe sole into the soaking conveyor belt, where it falls between two adjacent mesh plates. As the soaking conveyor belt carries the shoe sole into the chemical tank, a mesh cover limits the movement of the shoe sole, reducing the possibility of it floating and stacking. The soaking conveyor belt then sends the chemically soaked shoe sole to the second conveyor belt, where a dryer dries the shoe sole, and an irradiation machine irradiates the shoe sole to allow the chemical to take effect. After the worker places the shoe sole on the first conveyor belt, it sequentially passes through the hot air blower, chemical tank, dryer, and irradiation machine, thereby improving the continuity of the shoe sole pretreatment equipment production and thus increasing the efficiency of shoe sole pretreatment.

[0009] Optionally, multiple separators are fixedly installed on the surface of the first conveyor belt, and the portion of the first conveyor belt between two adjacent separators is used to insert the shoe sole. A first guide plate is fixedly installed at the discharge end of the first conveyor belt, and multiple separators are fixedly installed on the first guide plate. The separators and separators are arranged in a one-to-one correspondence.

[0010] By adopting the above technical solution, the first guide plate helps to fill the gap between the first conveyor belt and the soaking conveyor belt, thereby reducing the possibility of the shoe sole falling directly from the first conveyor belt and flipping over. The separator strips and plates limit the movement of the shoe sole, thus reducing the possibility of the shoe sole entering the first guide plate and the friction between the first guide plate and the shoe sole causing the shoe sole to deflect.

[0011] Optionally, the top side of the mesh plate is provided with multiple first clearance openings, and the top side of the mesh cover is provided with multiple second clearance openings. The first clearance openings and second clearance openings are staggered to allow the mesh cover to move up and down to avoid the mesh plate. Both sides of the soaking conveyor belt are fixedly installed with screws, and the screws are matched with nuts. Both sides of the mesh cover are provided with adjustment openings for the screws to move up and down.

[0012] By adopting the above technical solution, the nut is unscrewed, and the distance between the inner top wall of the mesh cover and the top side of the soaking conveyor belt is adjusted so that the distance between the inner top wall of the mesh cover and the top side of the soaking conveyor belt is less than twice the thickness of the shoe sole. This reduces the likelihood of the shoe sole floating up during soaking in the solution and then multiple shoe soles stacking on top of each other. After adjusting the position of the mesh cover, the nut is screwed into the screw rod, and the nut presses against the side wall of the mesh cover, thus facilitating the fixation of the mesh cover.

[0013] Optionally, a float is fixedly installed on the bottom side of the portion of the mesh cover located inside the medicine tank, the float being used to apply buoyancy to the mesh cover.

[0014] By adopting the above technical solution, the float applies buoyancy to the mesh cover, thereby reducing the occurrence of the mesh cover automatically moving downwards due to gravity.

[0015] Optionally, a second guide plate is fixedly installed between the feed ends of the second conveyor belt. The second guide plate is used to feed the shoe sole into the second conveyor belt by the soaking conveyor belt. The second guide plate has multiple third clearance openings, which are staggered with the first clearance openings to allow the second guide plate to avoid the mesh plate.

[0016] By adopting the above technical solution, the soaking conveyor belt feeds the shoe sole into the second guide plate, and then the shoe sole is fed into the second conveyor belt through the second guide plate. The third clearance opening and the first clearance opening are staggered to facilitate the second guide plate avoiding the mesh plate.

[0017] Optionally, the surface of the soaking conveyor belt is provided with waist-shaped holes.

[0018] By adopting the above technical solution, when the soaking conveyor belt carries the shoe sole out of the medicine tank, the medicine dripping from the shoe sole and the medicine on the soaking conveyor belt will be drained back into the medicine tank through the waist-shaped hole, thus facilitating the drainage of the shoe sole.

[0019] Optionally, a push plate is fixedly installed on the side of the mesh cover near the first conveyor belt. The push plate is used to push the shoe soles that fall on the top side of the mesh plate into the space between two adjacent mesh plates. A lifting rod is provided inside the second horizontal section. Lifting ports are opened on both inner side walls of the second horizontal section. The end of the lifting rod passes through the lifting port. Multiple top rods are fixedly installed at intervals on the body of the lifting rod. The lifting rod is arranged along the width direction of the soaking conveyor belt. A lifting assembly is installed on the lifting rod. The lifting assembly is used to drive the lifting rod to rise and fall. The rising and falling of the lifting rod is used to drive the top rods to pass through the waist-shaped holes.

[0020] By adopting the above technical solution, when the shoe sole is fed from the first conveyor belt into the soaking conveyor belt, the sole may directly rest on the top side of the mesh plate. A lifting assembly raises the lifting rod, and then a top rod passes through the waist-shaped hole and lifts the sole. Afterwards, the sole falls between two adjacent mesh plates under the push of the pusher plate, thereby reducing the coordination between the conveying speeds of the first conveyor belt and the soaking conveyor belt, and thus reducing the requirements for workers to place the sole on the first conveyor belt.

[0021] Optionally, both ends of the lifting rod have lifting components. The lifting components include a first swing arm and a first drive rod. One end of the first swing arm is hinged to one end of the lifting rod. The top side of the second horizontal section is provided with a rotating groove that communicates with the lifting port. The rotating groove communicates with the lifting port. The arm of the first swing arm is rotatably mounted on the inner wall of the rotating groove. One end of the first drive rod is fixedly mounted on one side of the mesh plate. The first drive rod is used to squeeze the first swing arm to rotate downward.

[0022] By adopting the above technical solution, the soaking conveyor belt drives the mesh plate to move, thereby causing the first drive rod to squeeze the first swing arm, and the end of the first swing arm away from the lifting rod rotates downward. The first swing arm drives the lifting rod to move upward, thus facilitating the lifting rod to rise.

[0023] After the first drive rod separates from the first swing arm, the first swing arm moves downward under the gravity of the lifting rod and the top rod, and the end of the first swing arm away from the lifting rod rotates upward, thereby facilitating the descent of the lifting rod.

[0024] Optionally, both ends of the lifting rod have lifting components, each including a take-up reel, a traction rope, a second drive rod, and a second swing arm. The top side of the second horizontal section has a placement slot communicating with the lifting port. The take-up reel is rotatably installed inside the placement slot. One end of the traction rope is fixedly connected to the take-up reel, and the other end of the traction rope is fixedly connected to one end of the lifting rod. One end of the second swing arm is fixedly installed on the periphery of the take-up reel, and one end of the second drive rod is fixedly connected to one side of the first mesh plate. The second drive rod and the second swing arm press against each other to push the take-up reel to rotate.

[0025] By adopting the above technical solution, the mesh plate drives the second drive rod to move, thereby causing the second swing arm to be repeatedly squeezed by the second drive rod, which in turn causes the winding reel to repeatedly wind and unwind the traction rope. By repeatedly winding and unwinding the traction rope, the lifting rod and the top rod are raised and lowered.

[0026] Optionally, an extension tank is fixedly installed on the side wall of the medicine tank near the first and second conveyor belts. The extension tank is connected to the medicine tank and is located below the second and fourth horizontal sections.

[0027] By adopting the above technical solution, the bottom of the tank is extended to receive the portion of the medicine dripping from the immersion conveyor belt outside the medicine tank, thereby reducing the waste of medicine.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The soaking conveyor belt sends the shoe soles into the chemical tank for soaking. During the soaking process, the mesh covers limit the floating height of the shoe soles, thereby reducing the possibility of the shoe soles stacking together after floating and moving. Then the soaking conveyor belt sends the shoe soles into the second conveyor belt, thereby improving the continuity of the shoe sole pretreatment equipment and thus improving the efficiency of shoe sole pretreatment.

[0030] 2. Unscrew the nut from the screw, loosen the mesh cover from the soaking conveyor belt, and make it easier to adjust the distance between the inner top wall of the mesh cover and the top side of the soaking conveyor belt. This allows the soaking conveyor belt to be used with shoe soles of different thicknesses. After adjusting the mesh cover, screw the nut back into the screw. The nut will press the side wall of the mesh cover tightly against the side wall of the soaking conveyor belt, thus making it easier to fix the mesh cover. Attached Figure Description

[0043] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0044] Example 1.

[0045] This application discloses a shoe sole pretreatment device.

[0046] Reference Figure 1 , Figure 2 A shoe sole pretreatment device includes a first conveyor belt 6, which comprises a first horizontal section 61 and a first descending section 62 along the conveying direction. A hot air blower 1 is installed on the first horizontal section 61. Workers place shoe soles into the feed end of the first conveyor belt 6, which then feeds the soles into the hot air blower 1. The hot air blower 1 heats the soles, causing them to expand.

[0047] The first conveyor belt 6 has multiple separator strips 2 fixedly installed on its surface. The portion of the first conveyor belt 6 between two adjacent separator strips 2 is used to place shoe soles, thus facilitating workers to neatly place shoe soles on the first conveyor belt 6.

[0048] Reference Figure 1 , Figure 3 , Figure 4 The discharge end of the first conveyor belt 6 is equipped with an immersion conveyor belt 7, which includes, in sequence along the conveying direction, a second horizontal section 71, a second descending section 72, a third horizontal section 73, an ascending section 74, and a fourth horizontal section 75. The first descending section 62 is located above the second horizontal section 71. The first conveyor belt 6 feeds the heated shoe soles into the immersion conveyor belt 7, which then carries the shoe soles to the next process.

[0049] Reference Figure 2, Figure 4 A first guide plate 3 is fixedly installed at the discharge end of the first conveyor belt 6. The first guide plate 3 is used to reduce the gap between the first descending section 62 and the second horizontal section 71, thereby reducing the occurrence of the shoe sole bouncing and flipping after hitting the soaking conveyor belt 7 when it enters the soaking conveyor belt 7 from the first conveyor belt 6.

[0050] The first guide plate 3 is fixedly equipped with multiple partition plates 5, with each partition plate 5 corresponding to a partition strip 2. After the first conveyor belt 6 feeds the shoe sole into the first guide plate 3, the shoe sole enters between two adjacent partition plates 5. The partition plates 5 limit the movement of the shoe sole, thereby reducing the friction between the shoe sole and the first guide plate 3 and preventing the shoe sole from flipping over.

[0051] Reference Figure 1 The discharge end of the first conveyor belt 6 is also equipped with a chemical tank 8. The second descending section 72, the third horizontal section 73, and the ascending section 74 are all located inside the chemical tank 8, and the second horizontal section 71 and the fourth horizontal section 75 are both erected on the top side of the chemical tank 8. The soaking conveyor belt 7 sends the shoe soles into the chemical tank 8, thus facilitating the soaking of the shoe soles inside the chemical tank 8.

[0052] Reference Figure 3 , Figure 4 The soaking conveyor belt 7 is fixedly equipped with multiple mesh plates 9 at intervals, and a mesh cover 10 is installed on the top side of the soaking conveyor belt 7. The distance between the inner top wall of the mesh cover 10 and the soaking conveyor belt 7 is greater than the thickness of the shoe sole, but less than twice the thickness of the shoe sole. After some shoe soles enter the chemical tank 8, they will float. The mesh cover 10 is used to limit the floating of the shoe soles, and the mesh plates 9 are used to push the shoe soles to move, thereby facilitating the soaking conveyor belt 7 to send the chemically soaked shoe soles to the next process.

[0053] Reference Figure 1 , Figure 4 Extension tanks 11 are fixedly installed on the side walls of the medicine tank 8 near the first conveyor belt 6 and the second conveyor belt 26. The extension tanks 11 are connected to the medicine tank 8 and are located below the second horizontal section 71 and the fourth horizontal section 75. The soaking conveyor belt 7 will carry some medicine out of the medicine tank 8, and the extension tanks 11 will catch the medicine dripping from the second horizontal section 71 and the fourth horizontal section 75, thereby reducing the waste of medicine.

[0054] Reference Figure 3 , Figure 5 The top side of the mesh panel 9 has multiple first clearance openings 12, and the top side of the mesh cover 10 has multiple second clearance openings 13. The first clearance openings 12 and the second clearance openings 13 are staggered to facilitate the mesh cover 10 moving up and down to avoid the mesh panel 9.

[0055] Both sides of the soaking conveyor belt 7 are fixedly installed with screws 14, and nuts 15 are matched to the screws 14. Adjustment ports 16 for the screws 14 to slide and rise are opened on both sides of the mesh cover 10. By unscrewing the nuts 15 from the screws 14, the soaking conveyor belt 7 is loosened on both sides of the mesh cover 10, thus facilitating the adjustment of the distance between the inner top wall of the mesh cover 10 and the top side of the soaking conveyor belt 7. The distance between the inner top wall of the mesh cover 10 and the top side of the soaking conveyor belt 7 is kept less than twice the thickness of the shoe sole, thus facilitating the use of the soaking conveyor belt 7 to transport shoe soles of different thicknesses.

[0056] Reference Figure 3 A float 17 is fixedly installed on the bottom side of the portion of the mesh cover 10 located inside the medicine tank 8. When the float 17 and the mesh cover 10 are immersed in the medicine, the sum of the buoyancy forces acting on the float 17 and the mesh cover 10 is less than the weight. When the nut 15 is screwed into the screw 14, pressing the nut 15 against the side wall of the mesh cover 10, not only is there the frictional force between the nut 15 and the mesh cover 10 for limiting the movement, but the float 17 also applies buoyancy to the mesh cover 10, thereby reducing the possibility of the mesh cover 10 automatically descending.

[0057] Reference Figure 5 The soaking conveyor belt 7 has multiple rows of waist-shaped holes 18 spaced apart along the conveying direction, with multiple holes in each row. When the soaking conveyor belt 7 removes the shoe sole from the solution, the solution on the soaking conveyor belt 7 drips through the waist-shaped holes 18, thus facilitating the drainage of the shoe sole.

[0058] Reference Figure 5 , Figure 6 A push plate 19 is fixedly installed on the side of the mesh cover 10 near the first conveyor belt 6. A lifting rod 20 is provided inside the second horizontal section 71, and the lifting rod 20 is arranged along the width direction of the soaking conveyor belt 7. Lifting openings 21 are provided on both inner side walls of the second horizontal section 71, and the end of the lifting rod 20 passes through the lifting opening 21, thereby facilitating the lifting and sliding of the lifting rod 20. The portion of the lifting rod 20 located inside the lifting opening 21 is rectangular, thus restricting the rotation of the lifting rod 20.

[0059] Reference Figure 6 , Figure 7 The lifting rod 20 has multiple top rods 22 fixedly installed at intervals on its body, and lifting components 23 are provided at both ends of the lifting rod 20. The lifting components 23 are used to drive the lifting rod 20 to rise and fall. When the lifting rod 20 drives the top rods 22 to rise and fall, the top rods 22 will enter and exit the waist-shaped hole 18.

[0060] The lifting assembly 23 includes a first swing arm 231 and a first drive rod 232. One end of the lifting rod 20 is hinged to one end of the first swing arm 231. A rotating groove 24 communicating with the lifting port 21 is provided on the top side of the second horizontal section 71. The arm of the first swing arm 231 is rotatably mounted on the inner wall of the rotating groove 24. One end of the first drive rod 232 is fixedly mounted on one side of the mesh plate 9.

[0061] After the soaking conveyor belt 7 is started, the screen plate 9 moves along with the soaking conveyor belt 7. When the first drive rod 232 of the screen plate 9 presses the first swing arm 231, the end of the first swing arm 231 away from the lifting rod 20 rotates downward, thereby causing the lifting rod 20 to move upward, and the top rod 22 passes through the waist-shaped hole 18.

[0062] If the sole rests on the top side of the mesh plate 9 and is tilted towards the side of the mesh plate 9 facing the transmission direction, the top rod 22 will lift the sole for the pusher plate 19 to press. After being pressed by the pusher plate 19, the sole falls between two adjacent mesh plates 9.

[0063] If the sole rests on the top side of the mesh plate 9 and the sole is tilted toward the side of the mesh plate 9 away from the transmission direction, the push plate 19 directly presses against the sole, thereby pushing the sole between two adjacent mesh plates 9.

[0064] If the sole is located between two adjacent mesh plates 9, the push rod 22 will first lift the end of the sole that is away from the transmission direction. After the first drive rod 232 separates from the first swing arm 231, the push rod 22 descends, thereby reducing the pressure of the push plate 19 on the sole located between the two adjacent mesh plates 9.

[0065] When the shoe soles are fed from the first conveyor belt 6 into the soaking conveyor belt 7, if it is necessary to keep the shoe soles between two adjacent mesh plates 9, the workers need to control the position of the shoe soles on the first conveyor belt 6, which increases the difficulty of the work. By using the push plate 19 and the top rod 22, the shoe soles placed on the mesh plates 9 can fall back between the two adjacent mesh plates 9, thereby reducing the difficulty of the work.

[0066] A second conveyor belt 26 is provided at the discharge end of the soaking conveyor belt. A dryer 27 and an irradiation machine 28 are sequentially installed on the second conveyor belt 26 along the conveying direction. The soaking conveyor belt 7 feeds the shoe soles into the second conveyor belt 26, and the second conveyor belt 26 sequentially feeds the shoe soles into the dryer 27 and the irradiation machine 28 for drying and irradiation.

[0067] Reference Figure 1 , Figure 8 A second guide plate 4 is fixedly installed between the feed ends of the second conveyor belt 26. The second guide plate 4 is used to feed the shoe soles into the second conveyor belt 26 by the soaking conveyor belt 7. The second guide plate 4 has multiple third clearance openings 29, which are staggered with the first clearance openings 12 to allow the second guide plate 4 to avoid the mesh plate 9.

[0068] The implementation principle of a shoe sole pretreatment device according to an embodiment of this application is as follows: Workers place the shoe soles into a first conveyor belt 6, which then sends the shoe soles into a hot air blower 1 for heating. The first conveyor belt 6 then sends the heated shoe soles into a soaking conveyor belt 7.

[0069] The soaking conveyor belt 7 sends the shoe sole into the chemical tank 8 for soaking. While the shoe sole is soaking, the mesh plate 9 pushes the shoe sole, facilitating the continued movement of the shoe sole by the soaking conveyor belt 7. The mesh cover 10 limits the distance between the shoe sole and the surface of the soaking conveyor belt 7 after the shoe sole floats up, thereby reducing the possibility of the shoe soles stacking together after floating and moving. After the shoe sole is soaked in the chemical solution, the soaking conveyor belt 7 sends the shoe sole to the second conveyor belt 26, which sends the shoe sole to the dryer 27 for drying, and then to the irradiation machine 28 for irradiation.

[0070] After the staff puts the shoe soles into the first conveyor belt 6, the shoe soles will pass through the hot air blower 1, the chemical tank 8, the dryer 27 and the irradiation machine 28 in sequence. The staff does not need to transfer the shoe soles in between, thereby improving the continuity of the shoe sole pretreatment equipment production and thus improving the efficiency of shoe sole pretreatment.

[0071] Example 2.

[0072] This application discloses a shoe sole pretreatment device.

[0073] Reference Figure 9 , Figure 10 , Figure 11 The difference between the shoe sole pretreatment device in this embodiment and Embodiment 1 is that the lifting assembly 23 includes a take-up reel 233, a traction rope 234, a second drive rod 235, and a second swing arm 236. A placement groove 25 communicating with the lifting port 21 is provided on the top side of the second horizontal section 71, and the take-up reel 233 is rotatably installed inside the placement groove 25. One end of the traction rope 234 is fixedly connected to the take-up reel 233, and the other end of the traction rope 234 is fixedly connected to one end of the lifting rod 20. One end of the second swing arm 236 is fixedly installed on the periphery of the take-up reel 233, and one end of the second drive rod 235 is fixedly connected to one side of the first mesh plate 9. The second drive rod 235 and the second swing arm 236 press against each other to push the take-up reel 233 to rotate.

[0074] The implementation principle of the shoe sole pretreatment equipment in this application embodiment is as follows: the soaking conveyor belt 7 drives the mesh plate 9 to move, thereby causing the second drive rod 235 to press the end of the second swing arm 236 away from the take-up reel 233 to rotate downward. The second swing arm 236 drives the take-up reel 233 to rotate, and the take-up reel 233 winds up the traction rope 234, thereby causing the lifting rod 20 to move upward, thus facilitating the upward movement of the lifting rod 20.

[0075] After the second drive rod 235 separates from the second swing arm 236, the take-up reel 233 unwinds the traction rope 234 under the gravity of the lifting rod 20 and the top rod 22. The end of the second swing arm 236 away from the take-up reel 233 rotates upward, thereby facilitating the descent of the lifting rod 20.

[0076] 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.
