Description

Technical Field

[0001] This invention discloses a shoe sole baking device and a shoe sole bonding process using the device, belonging to the field of shoe manufacturing equipment. Background Technology

[0002] Currently, the processes of applying glue and attaching soles in shoe manufacturing all require the use of ovens to dry the semi-finished products after applying glue or attaching soles.

[0003] In existing shoe material ovens, semi-finished shoe soles are placed on the oven's conveyor belt and then fed into the oven's baking chamber for baking. Finally, they are fed out via the same conveyor belt. During this process, one side of the semi-finished shoe sole always faces the conveyor belt. This side of the semi-finished shoe sole is easily blocked by the conveyor belt, resulting in uneven heating and affecting the overall baking quality. However, existing shoe material ovens do not yet have the ability to automatically flip the shoe soles inside the baking chamber.

[0004] In response to the above problems, a new improvement plan is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a shoe sole baking device and a shoe sole bonding process using the device in order to solve the above-mentioned problems.

[0006] This invention achieves the above-mentioned objective through the following technical solution: a shoe sole baking device, comprising a machine base, a conveyor belt, a baking chamber, and a control panel. The conveyor belt is equipped with a placement component for placing shoe soles. The placement component includes a limiting seat and an elevating seat, the height of which is greater than the height of the limiting seat. Both the limiting seat and the elevating seat are fixedly connected to the conveyor belt. The baking chamber is equipped with a flipping device, which includes a main body and a pushing mechanism. The main body is fixedly connected to the baking chamber. The bottom of the main body has a notch for the elevating seat to pass through. The side of the main body facing the elevating seat has a smoothly transitioning guide surface. The pushing mechanism includes a slider and a reciprocating component. The main body has a groove, and the slider is slidably disposed in the groove. The reciprocating assembly is connected to the slider in a transmission manner. The elevation seat can cause the reciprocating assembly to drive the slider. The reciprocating assembly includes a turntable, a rotating shaft, a spring, a drive rod, a follower rod, and a transmission rod. The turntable is fixedly connected to the rotating shaft, and the rotating shaft is rotatably connected to the main body. The spring is installed between the rotating shaft and the main body and is connected in a transmission manner to both the rotating shaft and the main body. The drive rod is fixedly connected to the turntable and faces downward in the vertical direction in its natural state. The drive rod can abut against the elevation seat in a transmission manner. One end of the follower rod is connected in a transmission manner to the turntable, and the other end of the follower rod is connected in a transmission manner to the transmission rod. The end of the transmission rod away from the follower rod is fixedly connected to the slider.

[0007] Preferably, a plurality of guide rods are rotatably provided on the main body, and the plurality of guide rods are arranged along the extension direction of the guide surface.

[0008] Preferably, an auxiliary rod is rotatably mounted on the raised seat.

[0009] Preferably, a limiting piece is fixedly connected to the side of the limiting seat near the raised seat, and the limiting piece is formed with an arc-shaped limiting groove.

[0010] Preferably, the limiting seat is rotatably provided with a release rod.

[0011] Preferably, a plurality of isolation strips are fixedly connected to the conveyor belt, and the plurality of isolation strips divide the conveyor belt into multiple material zones. The placement components and flipping devices are configured in multiple groups, and each group corresponds to one material zone.

[0012] Preferably, the baking chamber is provided with shielding curtains on both sides, and the shielding curtains are fixedly connected to the baking chamber at only one end.

[0013] A sole bonding process includes the following steps:

[0014] Step 1: Place the midsole, carbon plate, and CPU together. Apply glue to the upper and lower midsole layers for the first time. Apply glue to the carbon plate and attach it to the upper layer. After applying glue, put it into the baking chamber for the first baking for 105-125 seconds.

[0015] Step 2: After the first baking, the carbon plate and the upper midsole are bonded together. Apply a second layer of glue to the upper and lower midsoles, and then put them into the baking chamber for a second baking, which takes 105-125 seconds.

[0016] Step 3: After the second baking, the upper and lower midsole layers are bonded together. The midsole is attached to the CPU side and glue is applied to the CPU side. Then, it is put into the baking chamber for the third baking, which takes 135-145 seconds.

[0017] Step 4: Apply the bottom layer. Place the CPU onto the CPU surface that was treated in Step 3, and then put it into the baking chamber for the fourth baking, which takes 105-125 seconds.

[0018] Step 5: Press the bottom. Use a water press to press the bottom for 8 seconds at a pressure of 18kgf-22kgf, then use a high-pressure press to press the bottom for 6 seconds at a pressure of 38kgf-42kgf. Then put it into the baking chamber for the fifth baking, and bake for 65-85 seconds.

[0019] Step 6: Freeze-set, clean, inspect for quality, and finally package and ship.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] By setting up a placement component for placing materials and adding a turning device to the baking chamber, when the semi-finished material enters the baking chamber for baking, the side facing upwards will be baked more evenly first. After baking for a certain period of time, the turning device will automatically turn the semi-finished material over in the baking chamber so that the other side faces upwards. Then, baking can continue, ensuring that both sides are baked evenly, improving the quality of the finished product, and eliminating the need for manual turning. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. In this description, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 6 As shown, a shoe sole baking device includes a machine base 1, on which a conveyor belt 2, a baking chamber 3, and a control panel 4 are installed. The conveyor belt 2 is driven by a motor inside the machine base 1 to move the material forward into the baking chamber 3. The baking chamber 3 integrates a hot air system for baking the material. The control panel 4 is used to control the temperature of the baking chamber 3, the baking time, and the operation of the conveyor belt 2. A placement component for placing shoe soles is installed on the conveyor belt 2. The placement component includes a limiting seat 5 and a raising seat 6. The height of the raising seat 6 is greater than the height of the limiting seat 5. Both the limiting seat 5 and the raising seat 6 are fixedly connected to the conveyor belt 2. When using this product, the operator places the pre-treated shoe sole material into the placement component, specifically with one end of the shoe sole abutting against the limiting seat 5 and the toe of the shoe sole resting on the raising seat 6. A flipping device is installed inside the baking chamber 3. The flipping device includes a main body 7 and a pushing mechanism. The main body 7 is fixedly connected to the baking chamber 3, and a notch 71 is opened at the bottom of the main body 7 for the raising seat 6 to pass through. The main body 7 has a smoothly transitioning guide surface 72 formed on the side facing the raised seat 6. The pushing mechanism includes a slider 8 and a reciprocating assembly 9. A groove 73 is provided on the main body 7, and the slider 8 is slidably disposed in the groove 73. The reciprocating assembly 9 is connected to the slider 8 in a transmission manner. The raised seat 6 can cause the reciprocating assembly 9 to drive the slider 8. During the operation of the equipment, the conveyor belt 2 first sends the placed shoe sole material into the baking chamber 3 for baking. When the conveyor belt 2 delivers the shoe sole material to the flipping device, the conveyor belt 2 stops working. At this time, the shoe sole material stays in the baking chamber 3, and its upward-facing side will be more completely and evenly baked by the hot air. After this side is baked, the control panel 4 will control the conveyor belt 2 to continue moving forward, so that the raised seat 6 passes through the notch 71 under the main body 7. Since the toe part of the shoe sole has a certain degree of curvature, and the main body 7 has a smoothly transitioning guide surface 72, the shoe sole is pressed against the main body 7 and will climb along the guide surface 72, thus gradually standing up. Figure 4 and Figure 5 As shown, the conveyor belt 2 then drives the placement component forward, and the raised seat 6 begins to abut against the reciprocating drive component 9, thereby causing the reciprocating drive component 9 to push the slider 8 to slide. After the slider 8 is pushed out, it will extend from the groove 73 of the main body 7, thereby pushing out the sole material leaning against the main body 7, which plays the role of pushing the sole material over, thereby causing the sole material to tilt in the opposite direction to achieve the effect of flipping. After the flipping is completed, hot air continues to blow out of the baking chamber 3 to bake the other side of the sole material comprehensively and evenly. The whole process does not require manual intervention. The flipping process is completed in the baking chamber 3, and the sole material will not experience a sudden drop in temperature due to the need to leave the baking chamber 3 for flipping, which is more beneficial to the sole bonding process.

[0033] like Figure 7 As shown, the reciprocating assembly 9 includes a turntable 91, a rotating shaft 92, a spring 93, a drive rod 94, a follower rod 95, and a transmission rod 96. The turntable 91 is fixedly connected to the rotating shaft 92, which is rotatably connected to the main body 7. The spring 93 is installed between the rotating shaft 92 and the main body 7 and is connected to both the rotating shaft 92 and the main body 7. The drive rod 94 is fixedly connected to the turntable 91 and faces downwards in the vertical direction in its natural state. The drive rod 94 can abut against the raised seat 6 for transmission. One end of the follower rod 95 is connected to the turntable 91 for transmission, and the other end is connected to the transmission rod 96 for transmission. The end of the transmission rod 96 away from the follower rod 95 is fixedly connected to the slider 8. During the operation of the equipment, when it is necessary to flip the shoe, the raised seat 6 moves through the notch 71 of the main body 7 towards the drive rod 94. The limit seat 5 pushes the sole material to climb along the guide surface 72 on the main body 7. When the 6th movement reaches the point of contact with the drive rod 94, the conveyor belt 2 continues to drive the 6th elevation seat forward, thereby pushing the drive rod 94, causing the turntable 91 to rotate. When the turntable 91 rotates, it drives the shaft 92 to rotate and simultaneously drives the spring 93 to store power. At this time, the follower rod 95 is driven by the rotation of the turntable 91, thereby transmitting the rotational motion of the turntable 91 to the transmission rod 96 and converting it into linear motion. This achieves the effect of using the transmission rod 96 to push the slider 8 out of the groove 73. After the slider 8 is pushed out, it will push away the shoe sole material leaning against the main body 7, causing it to tilt in the opposite direction, thus completing the flipping operation. After the 6th elevation seat has completely passed through the drive rod 94, the drive rod 94 loses the contact of the 6th elevation seat, and the spring 93 begins to reset, driving the shaft 92 and the turntable 91 to rotate, so that the drive rod 94 returns to its natural state facing downwards in the vertical direction.

[0034] like Figures 4-7 As shown, a number of guide rods 10 are rotatably mounted on the main body 7. The guide rods 10 are arranged along the extension direction of the guide surface 72. By adding the guide rods 10 that can rotate freely, the friction of the shoe sole material is reduced during the process of climbing along the guide surface 72, and the climbing process is smoother.

[0035] Combined Figure 8 As shown, an auxiliary rod 11 is rotatably mounted on the raised seat 6. This design serves the same purpose as the guide rod 10, ensuring that the sole material contacts the rotatable auxiliary rod 11 when it is placed on the raised seat 6. When the sole material is about to leave the raised seat 6 and climb along the guide surface 72, the auxiliary rod 11 can help reduce friction. Furthermore, a limiting plate 12 is fixedly connected to the side of the limiting seat 5 near the raised seat 6. The limiting plate 12 has an arc-shaped limiting groove 13. Since the heel of the sole is usually arc-shaped, the addition of the arc-shaped limiting groove 13 provides a suitable solution. The limiting piece 12 can better hold the sole material in place and prevent it from shifting laterally. Furthermore, the limiting seat 5 of this product is rotatably equipped with a release rod 14. During the flipping process, after the sole material is tilted in the opposite direction, some of it may still overlap with the limiting seat 5. Although this does not affect its baking, by adding the rotatable release rod 14, when some of the sole material that is tilted in the opposite direction overlaps with the release rod 14, the limiting seat 5 continues to move forward, and the rotating release rod 14 can be used to let the sole material fall off, thus achieving the effect of detaching from the limiting seat 5.

[0036] like Figure 1 and Figure 2 As shown, several isolation strips 15 are fixedly connected to the conveyor belt 2, which divides the conveyor belt 2 into multiple material areas. The placement components and flipping devices are set in multiple groups and correspond one-to-one with each material area. The isolation strips 15 separate the conveyor belt 2, so that the operators can have better area reference when placing materials and avoid interference between adjacent materials. Finally, the baking chamber 3 is equipped with shielding curtains 16 on both sides. Only one end of the shielding curtains 16 is fixedly connected to the baking chamber 3. By adding shielding curtains 16, the materials can easily pass through the shielding curtains 16, and a certain heat preservation effect can also be achieved.

[0037] This invention also includes a sole bonding process, which utilizes a sole baking device as described in this invention to produce soles, comprising the following steps:

[0038] Step 1: Place the midsole, carbon plate, and CPU together. Apply glue to the upper and lower midsole layers for the first time. Apply glue to the carbon plate and attach it to the upper layer. After applying glue, put it into the baking chamber 3 for the first baking for 105-125 seconds.

[0039] Step 2: After the first baking, the carbon plate and the upper midsole are bonded together. Apply a second layer of glue to the upper and lower midsoles, and then put them into baking chamber 3 for a second baking for 105-125 seconds.

[0040] Step 3: After the second baking, the upper and lower midsole layers are bonded together. The midsole is attached to the CPU side and glue is applied to the CPU side. Then, it is placed in baking chamber 3 for the third baking, which takes 135-145 seconds.

[0041] Step 4: Apply the bottom layer. Apply the CPU to the CPU surface that was treated in Step 3, and then put it into baking chamber 3 for the fourth baking, baking time 105-125 seconds.

[0042] Step 5: Press the bottom down. Use a water press to press the bottom down for 8 seconds at a pressure of 18-22 kgf, then use a high-pressure press to press the bottom down for 6 seconds at a pressure of 38-42 kgf. The unit kgf is kilogram-force, which is actually 18-22 kgf / cm², and is converted to the internationally used unit 1.8-2.2 MPa. Then, put it into baking chamber 3 for the fifth baking for 65-85 seconds.

[0043] Step 6: Freeze-set, clean, inspect for quality, and finally package and ship;

[0044] Specifically, since this process requires entering the baking chamber 3 five times, five sections of the equipment described in this invention can be combined, with each section corresponding to one workstation, to achieve a production line effect. In step one, the temperature is set to 52±3℃ via control panel 4, and then the processed shoe sole material is sent into the baking chamber 3 for baking, with a baking time of 105-125 seconds per side. In step two, the temperature is first set to 52±3℃ via control panel 4 to bake the upper layer of the shoe sole material for 105-125 seconds. After flipping, the temperature is increased to 55±3℃ to bake the lower layer of the shoe sole material for 105-125 seconds. In step three, the temperature is first set to 52±3℃ via control panel 4 to bake the upper layer of the sole material for 135-145 seconds. After flipping it over, the temperature is increased to 55±3℃ to bake the lower layer of the sole material for 135-145 seconds. In step four, the temperature is adjusted to 50±3℃ via control panel 4 to bake the sole material for 105-125 seconds per side. In step five, the temperature is adjusted to 50±3℃ via control panel 4 to bake the sole material for 65-85 seconds per side. Finally, the material can be transferred to other workstations for freezing, cleaning, quality inspection, and finally packaging and shipping.
