Description

Technical Field

[0001] The present application relates to the field of sole production technology, and in particular to a sole production device. Background Art

[0002] The sole is an important part of the shoe and is the part that comes into direct contact with the ground.

[0003] Related technology sole production equipment such as Figure 1 As shown, it includes a sole mold 2, which includes a fixed mold 21 and a movable mold 22 hinged on the fixed mold 21. Both the fixed mold 21 and the movable mold 22 are provided with molding grooves 23. When the movable mold 22 is rotated to be clamped on the fixed mold 21, the two molding grooves 23 on the movable mold 22 and the fixed mold 21 jointly form a molding cavity for molding the sole. The movable mold 22 is provided with an injection port 24 connecting the outside world and the molding grooves 23. An injection molding machine is used to inject molten injection material into the molding cavity from the injection port 24. After the injection material cools, the movable mold 22 is opened and the molded sole can be taken out.

[0004] The above-mentioned related technical solutions have the following defects: the operator cannot perform other operations while waiting for the injection molding material to cool down, and can only take out the sole after cooling down before performing the next injection molding, resulting in low production efficiency of the sole. Summary of the Invention

[0005] In order to improve the production efficiency of soles, the present application provides a sole production equipment.

[0006] The present application provides a shoe sole production equipment adopting the following technical solution:

[0007] A sole production equipment includes a sole mold, which includes a locking device, a fixed mold and a movable mold hinged on the fixed mold. The fixed mold and the movable mold are both provided with molding grooves, and the movable mold is provided with an injection port connecting the outside world and the molding grooves. When the movable mold is rotated to be clamped on the fixed mold, the locking device is used to lock the movable mold on the fixed mold. The two molding grooves on the movable mold and the fixed mold together form a molding cavity for molding the sole. The equipment also includes a workbench, a driving member, a turntable and an injection molding device. The injection molding device is arranged on the workbench. There are multiple sole molds. The turntable is connected to the workbench by rotating along the axial direction. The fixed molds of the multiple sole molds are distributed in sequence on the top surface of the turntable along the circumferential direction of the turntable. The driving member is used to drive the turntable to rotate so that the multiple sole molds pass through the injection molding device in sequence. The injection molding device is used to inject molten injection molding material into the injection ports of the corresponding sole molds.

[0008] By adopting the above technical solution, the injection molding equipment injects the molten injection molding material into the injection molding port of the corresponding sole mold, and then the turntable rotates one circle, the sole cools and is formed, and then the operator opens the movable mold to remove the sole, and then closes the movable mold again. The sole mold will follow the rotation of the turntable and pass through the injection molding equipment again, and be injected again. The operator only needs to work at one workstation, constantly taking out the soles formed by different sole molds and then closing the mold, which can greatly improve the production efficiency of the sole.

[0009] Preferably, there are two movable molds and two locking devices. The two movable molds are respectively hinged on the adjacent side surfaces of the fixed mold. The two movable molds can be closed with the fixed mold respectively. The two locking devices correspond to the two movable molds respectively, and the locking devices are used to lock the corresponding movable molds on the fixed mold.

[0010] By adopting the above technical solution, the advantage of setting up two movable molds is that the two movable molds can be used alternately. When one of the movable molds is closed on the fixed mold, the other movable mold can be cooled on the side, which can extend the service life of the mold and improve production efficiency.

[0011] Preferably, the locking device includes a card block and a buckle, the buckle is rotatably connected to the end of the corresponding movable mold away from the hinge axis, and the card block is fixed on the side surface of the fixed mold away from the corresponding movable mold hinge axis. When the movable mold is closed on the fixed mold, the buckle is buckled on the card block.

[0012] By adopting the above technical solution, when the movable mold is closed on the fixed mold, the operator can conveniently fix the fixed mold and the fixed mold by flipping the buckle to buckle on the clamping block, thereby reducing the probability of defective products caused by the movable mold separating from the fixed mold during the injection molding process.

[0013] Preferably, the turntable is provided with a first support rod and a second support rod, and the first support rod and the second support rod are respectively used to support the two movable molds in the open state and to leave a gap between the corresponding movable molds and the turntable for a hand to be inserted.

[0014] By adopting the above technical solution, the first support rod and the second support rod are respectively used to support the two movable molds in the open state, so that a gap is left between the movable mold and the turntable, which is convenient for the operator to reach into the gap and apply force to the movable mold to flip it over to close the mold on the fixed mold.

[0015] Preferably, it also includes an unlocking device, which is used to drive the buckle to disengage from the blocking block. The unlocking device includes a second driving member, a cylinder and multiple groups of top blocks, the multiple groups of top blocks correspond to multiple sole molds respectively, each group of top blocks includes two top blocks, and the two top blocks correspond to two locking devices respectively. The top blocks are slidably connected to the turntable along the axis direction perpendicular to the rotation of the corresponding buckle, and an extension rod is provided on the buckle. When the buckle is buckled on the blocking block, the top block is located directly below the corresponding extension rod. A fixed seat is provided on the workbench, and the cylinder is located below the turntable and slidably connected to the fixed seat. The second driving member drives the cylinder to slide back and forth between the two top blocks of the corresponding sole mold, and the length direction of the cylinder piston rod is parallel to the sliding direction of the top block. The piston rod of the cylinder is used to lift the top block. When the cylinder moves to face the corresponding top block and the piston rod of the cylinder extends, the top block lifts the corresponding extension rod and causes the buckle to disengage from the blocking block.

[0016] By adopting the above technical solution, the cylinder is driven to move by driving member 2 so that the cylinder is aligned with the top block corresponding to the buckle to be unlocked, and then the piston rod of the cylinder is driven to extend, so that the top block moves up to lift the buckle, thereby making the buckle disengage from the corresponding block and achieving the purpose of unlocking.

[0017] Preferably, the second driving member includes a second spring, a receiving block and a moving block, the receiving block is slidably connected to the fixed seat along a sliding direction parallel to the top block, the moving block is slidably connected to the fixed seat along a sliding direction parallel to the cylinder, the cylinder is fixed on the moving block, the receiving block is located above the moving block, and a first inclined surface is provided on the side surface of the receiving block and the moving block facing each other, the second spring is used to drive the moving block to always move until the two first inclined surfaces abut each other, the first support rod is slidably connected to the turntable along the sliding direction parallel to the receiving block, and the first support rod is provided with a first spring for driving the first The support rod moves upward, and when the corresponding movable mold abuts against the first support rod, the bottom end of the first support rod can extend to the bottom of the turntable and abut against the receiving block. The receiving block is provided with a second inclined surface on the side surface facing the first support rod along the moving direction of the turntable. When there is no external force, the second inclined surface of the receiving block is located above the fixed seat and is used to receive the first support rod. Every time the turntable rotates once and the corresponding movable mold abuts against the first support rod, the cylinder moves to face the top block on the unlocking device corresponding to the other movable mold. When the corresponding movable mold moves away from the first support rod, the cylinder moves to face the top block on the unlocking device corresponding to the corresponding movable mold.

[0018] By adopting the above technical solution, when the movable mold corresponding to the first support rod is in the open state, the movable mold will abut against the first support rod and drive the first support rod to move downward. After the turntable rotates, the first support rod moves along the second inclined surface until it abuts against the top surface of the receiving block. Since the weight of the movable mold presses the first support rod, the height position of the first support rod remains unchanged, and the height position of the receiving block will move downward. Then, under the action of the first inclined surface, the moving block overcomes the elastic force of the spring and moves, thereby driving the cylinder to move, so that the cylinder automatically moves to the bottom of the corresponding top block.

[0019] Preferably, a ball groove is provided at the bottom end of the first support rod, and a rolling ball is provided on the ball joint of the ball groove.

[0020] By adopting the above technical solution, since the bottom end of the first support rod will abut against the second inclined surface and move when the turntable rotates, there will be relatively large friction between the first support rod and the second inclined surface. A rolling ball is used instead of the bottom end of the first support rod abutting against the second inclined surface. When the first support rod moves with the turntable, the rolling ball will roll on the second inclined surface, thereby reducing the friction between the first support rod and the second inclined surface, thereby improving the service life of the first support rod.

[0021] Preferably, a first groove is provided at the top end of the first support rod, a buffer rod is slidably connected in the first groove along the depth direction of the first groove, a third spring is provided in the first groove, two ends of the third spring are respectively fixed on the bottom wall of the first groove and the bottom surface of the buffer rod, the first groove is located in a space below the buffer rod and is in a closed state, a channel is provided in the first support rod, two ends of the channel are respectively connected to the bottom end of the first groove and the outside world, the channel passes through the ball groove and is connected to the ball groove, the buffer rod is used to receive one of the movable molds in the open state, the ball rotates once each time the buffer rod slides, and the rotation direction of the ball is different from the rotation direction of the ball on the second inclined surface.

[0022] By adopting the above technical solution, when the ball abuts against the second inclined surface and rotates, the ball will inevitably wear. Since the rotation direction of the ball on the second inclined surface is fixed, it will cause uneven wear at different positions of the ball. At this time, by setting a buffer rod, when the corresponding movable mold abuts against the buffer rod or moves away from the buffer rod, the size of the space of the first groove below the buffer rod will change. If the space of the first groove below the buffer rod becomes smaller, the gas in the first groove enters the outside through the channel, and the airflow flowing in the channel will drive the ball to rotate; if the space of the first groove below the buffer rod becomes larger, the outside gas enters the first groove through the channel, and the airflow flowing in the channel will also drive the ball to rotate.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] By setting up a turntable and multiple injection molding equipment, the operator only needs to work at one station, constantly taking out the soles formed by different sole molds and then closing the mold, which can greatly improve the production efficiency of the soles;

[0025] The advantage of setting up two movable molds is that they can be used alternately. When one movable mold is clamped on the fixed mold, the other movable mold can be cooled on the side, which can extend the service life of the mold and improve production efficiency.

[0036] The following is combined with Figure 2-9 This application is described in further detail.

[0037] The embodiment of the present application discloses a shoe sole production device.

[0038] Reference Figure 2 、 Figure 3 A sole production device of this embodiment includes a workbench 1, a driving member 11, a turntable 12, an injection molding device 13 and a plurality of sole molds 2. The central axis of the turntable 12 is vertically arranged, and the turntable 12 is connected to the workbench 1 along the axial direction. The driving member 11 is used to drive the turntable 12 to rotate. The driving member 11 is a stepping motor 111. The stepping motor 111 is fixed on the workbench 1, and the output shaft of the stepping motor 111 is vertically arranged upward and coaxially fixed on the turntable 12.

[0039] Reference Figure 2 、 Figure 4 The sole mold 2 includes a fixed mold 21, two movable molds 22, and two locking devices 25. The multiple fixed molds 21 are evenly fixed to the top surface of the turntable 12 along the circumference of the turntable 12. The two movable molds 22 are hinged to the adjacent side surfaces of the fixed molds 21, with the hinge axes of the two movable molds 22 parallel to the length and width of the fixed molds 21. The two movable molds 22 can be respectively clamped with the fixed mold 21. The two locking devices 25 correspond to the two movable molds 22. When the corresponding movable mold 22 is rotated to clamp on the fixed mold 21, the corresponding locking device 25 is used to lock the corresponding movable mold 22 on the fixed mold 21.

[0040] Reference Figure 3 、 Figure 4 The top surface of the fixed mold 21 and the bottom surface of the movable mold 22 in the closed state are both provided with molding grooves 23. When the movable mold 22 rotates to close on the fixed mold 21, the two molding grooves 23 on the movable mold 22 and the fixed mold 21 together form a molding cavity for molding the sole. An injection port 24 is provided at the center of a side surface of the fixed mold 21 away from the molding groove 23 and connected to the molding groove 23. The injection molding device 13 is arranged on the workbench 1 and is driven by a stepping motor 111 to rotate at a certain angle, so that multiple sole molds 2 pass through the injection molding device 13 in sequence. The injection molding device 13 is used to inject molten injection molding material into the injection ports 24 of the corresponding sole molds 2.

[0041] Reference Figure 2 、 Figure 3 The injection molding equipment 13 includes a support frame 132, an oil cylinder 131, a cover body 133 and an injection molding machine. The support frame 132 is fixedly supported on the ground, and the cover body 133 is slidably connected to the support frame 132 in the vertical direction. An open groove for accommodating the sole mold 2 is provided on the bottom surface of the cover body 133. The oil cylinder 131 is fixed on the support frame 132 and the piston rod of the oil cylinder 131 is fixed on the cover body 133. The injection molding machine is installed on the cover body 133. The injection molding machine is used to inject the injection molding material into the injection port 24. An electric heating tube is installed on the inner wall of the cover body 133 to heat and melt the injection molding material.

[0042] Reference Figure 2 、 Figure 3 When the piston rod of the oil cylinder 131 extends vertically downward, in conjunction with the rotation of the turntable 12, the cover body 133 covers the sole mold 2 facing the turntable 12, and the injection molding machine then injects the molten injection material into the molding cavity from the injection port 24, thereby realizing automatic injection molding of the sole mold 2.

[0043] Reference Figure 2 、 Figure 4 , injection molding equipment 13 injects molten injection molding material into the injection port 24 of corresponding sole mold 2, then rotating disk 12 makes a circle and comes down, sole cooling molding, then operating personnel opens movable mold 22 and takes off sole, then movable mold 22 matched moulds again, this sole mold 2 can follow rotating disk 12 to rotate through injection molding equipment 13 again, is reinforced injection molding again, operating personnel only uses and operates on a station, constantly takes out the sole after different sole molds 2 are molded and then closes movable mold 22 and gets final product, can improve the production efficiency of sole to a large extent.Simultaneously by two movable molds 22 being set, two movable molds 22 can be used alternately, and when one of them movable mold 22 matched moulds was on fixed die 21, another movable mold 22 can cool aside, can prolong the service life of sole mold 2, improves production efficiency simultaneously.

[0044] Reference Figure 2 、 Figure 4The locking device 25 includes a block 251 and a buckle 252. One end of the movable mold 22 in the length direction is hinged to the fixed mold 21, and the buckle 252 is hinged to the other end of the movable mold 22 in the length direction in a direction parallel to the hinge axis of the corresponding movable mold 22. The block 251 is fixed on the side surface of the fixed mold 21 away from the hinge axis of the corresponding movable mold 22. When the movable mold 22 is closed on the fixed mold 21, the buckle 252 is buckled on the block 251.

[0045] Reference Figure 2 、 Figure 5 , the turntable 12 is provided with a first support rod 14 and a second support rod 15, referring to Figure 2 、 Figure 6 The first support rod 14 and the second support rod 15 are respectively used to support the two movable molds 22 in the open state. The second support rod 15 is fixed to the top surface of the turntable 12. The first support rod 14 is vertically slidably connected to the turntable 12. The side walls of the first support rod 14 are fixed with side blocks 141. The turntable 12 is provided with multiple vertical slots 121, each of which corresponds to a plurality of side blocks 141. The side blocks 141 are vertically slidably connected to the corresponding vertical slots 121. A first spring 142 is installed in the vertical slots 121. The ends of the first spring 142 are respectively fixed to the bottom walls of the side blocks 141 and the bottom walls of the vertical slots 121. The first spring 142 is always in a compressed state. When the movable mold 22 is opened and abuts against the first support rod 14 or the second support rod 15, a gap is left between the movable mold 22 and the turntable 12 for the operator to reach into the gap and apply force to the movable mold 22 to flip it over and close it on the fixed mold 21.

[0046] Reference Figure 7 、 Figure 8 , a sole production device further includes an unlocking device 3, the unlocking device 3 is used to drive the buckle 252 to disengage from the block 251. Figure 8 、 Figure 9 The unlocking device 3 includes a driving member 31, a cylinder 32 and multiple groups of top blocks 33. The multiple groups of top blocks 33 correspond to multiple sole molds 2. Each group of top blocks 33 includes two top blocks 33. The two top blocks 33 correspond to two locking devices 25. Figure 5 、 Figure 8 The top block 33 is connected to the turntable 12 by sliding in the vertical direction. In order to prevent the top block 33 from sliding out of the turntable 12, a limit block 331 is sleeved on the outer wall of the top block 33. The turntable 12 is provided with a limit groove 122 that matches the corresponding limit block 331. The limit block 331 is connected to the limit groove 122 by sliding in the vertical direction. Figure 8 、 Figure 9An extension rod 253 for manual force application is fixed to the buckle 252. The operator can apply force to the extension rod 253 to buckle the buckle 252 onto the clamping block 251. When the buckle 252 is buckled onto the clamping block 251, the top block 33 is located directly below the corresponding extension rod 253. When there is no external force acting on the top block 33, the top block 33 moves downward and away from the corresponding extension rod 253.

[0047] Reference Figure 7 、 Figure 9 , a fixed seat 16 is fixed on the workbench 1, and a cylinder 32 is located below the turntable 12 and is slidably connected to the fixed seat 16. The second driving member 31 drives the cylinder 32 to slide back and forth between the two top blocks 33 corresponding to the sole mold 2. The piston rod of the cylinder 32 is vertically upwardly arranged and used to lift the top block 33. Figure 9 The cylinder 32 is driven to move by the driving member 2 31 so that the cylinder 32 is aligned with the top block 33 corresponding to the buckle 252 to be unlocked, and then the piston rod of the cylinder 32 is driven to extend so that the top block 33 moves up to lift the buckle 252, thereby making the buckle 252 disengage from the corresponding block 251, thereby achieving the purpose of unlocking.

[0048] Reference Figure 2 、 Figure 8 The two ejector blocks 33 are positioned in a first position 332 and a second position 333, respectively. When one movable mold 22 abuts the first support rod 14 and the other movable mold 22 is in mold closing mode, the ejector block 33 in the first position 332 needs to be lifted to unlock the closed movable mold 22. When one movable mold 22 abuts the second support rod 15 and the other movable mold 22 is in mold closing mode, the ejector block 33 in the second position 333 needs to be lifted to unlock the closed movable mold 22.

[0049] Reference Figure 2 、 Figure 9 The second driving member 31 includes a second spring 311, a receiving block 312, and a moving block 313. The receiving block 312 is slidably connected to the fixed seat 16 in the vertical direction. The fixed seat 16 has a transverse groove 161. The moving block 313 is slidably connected to the transverse groove 161 in a direction parallel to the sliding direction of the cylinder 32. The cylinder 32 is fixed to the top surface of the moving block 313. The receiving block 312 is located above the moving block 313. A first inclined surface 314 is defined on the side of the receiving block 312 and the moving block 313 facing each other. The second spring 311 is located in the transverse groove 161. The two ends of the second spring 311 respectively abut against the inner wall of the transverse groove 161 and the moving block 313. Under the action of the second spring 311, the two first inclined surfaces 314 are always in contact with each other.

[0050] Reference Figure 5 、 Figure 9When the corresponding movable mold 22 is opened to abut against the first support rod 14, the bottom end of the first support rod 14 can extend below the turntable 12 and abut against the receiving block 312. Since the rotation direction of the turntable 12 is unchanged, the movement path of the first support rod 14 corresponding to each sole mold 2 is also unchanged. Figure 7 、 Figure 9 In order to enable the first support rod 14 to abut against the receiving block 312, the receiving block 312 is provided with a second inclined surface 315 on the side facing the first support rod 14 along the moving direction of the turntable 12. When the first support rod 14 has not yet come into contact with the second inclined surface 315 during movement, the height of the second inclined surface 315 gradually increases from the end closest to the first support rod 14 to the end farther away from the first support rod 14. When no external force acts on the receiving block 312, the moving block 313, under the action of the second spring 311, moves toward the second position 333 until the cylinder 32 is directly below the upper block 33 of the second position 333. The moving block 313 then drives the receiving block 312 upward so that the second inclined surface 315 is located above the fixed seat 16 and serves to receive the first support rod 14.

[0051] Reference Figure 7 、 Figure 9 When the turntable 12 rotates to bring the next sole mold 2 closer to the fixed seat 16, and at the same time, the corresponding movable mold 22 of the next sole mold 2 abuts against the first support rod 14, the bottom end of the first support rod 14 gradually abuts against the second inclined surface 315 as the turntable 12 rotates, pushing the receiving block 312 downward until the turntable 12 stops rotating. At this time, the bottom end of the first support rod 14 abuts against the top surface of the receiving block 312, and the first support rod 14 is now located above the fixed seat 16. The downward movement of the receiving block 312 drives the movable block 313 to overcome the elastic force of the second spring 311 and move toward the first position 332, so that the cylinder 32 is located directly below the top block 33 on the first position 332. This realizes the action of the cylinder 32 automatically moving to the bottom of the top block 33 that needs to be unlocked.

[0052] Reference Figure 2 、 Figure 6The first support rod 14 has a ball groove 143 at its bottom end. A ball 17 is hinged on the ball groove 143. The ball 17 replaces the bottom end of the first support rod 14 and abuts against the receiving block 312. The first support rod 14 has a first groove 144 at its top end. A buffer rod 18 is vertically slidably connected to the first groove 144. A third spring 145 is mounted within the first groove 144. The ends of the third spring 145 are fixed to the bottom wall of the first groove 144 and the bottom surface of the buffer rod 18, respectively. The space below the buffer rod 18 in the first groove 144 is sealed. A channel 146 is defined within the first support rod 14. The ends of the channel 146 connect the bottom end of the first groove 144 to the outside world, respectively. The channel 146 passes through the ball groove 143 and communicates with the ball groove 143. The buffer rod 18 replaces the top end of the first support rod 14 and is used to receive one of the movable molds 22 in the open state. The elastic force of the third spring 145 is less than that of the first spring 142.

[0053] Reference Figure 2 、 Figure 6 When the corresponding movable mold 22 opens to abut against the buffer rod 18, the buffer rod 18 first moves down to the limit position and then drives the first support rod 14 to move down. In order to prevent the third spring 145 from being crushed, a receiving ring 1441 is fixed on the inner wall of the bottom end of the first groove 144 to receive the buffer rod 18. Figure 6 、 Figure 9 Each time the buffer rod 18 slides, the ball 17 rotates once, and the rotation direction of the ball 17 is different from the rotation direction of the ball 17 on the second inclined surface 315 .

[0054] Reference Figure 6 、 Figure 9 When the ball 17 abuts against the second inclined surface 315 and rotates, the ball 17 will inevitably wear. Since the rotation direction of the ball 17 on the second inclined surface 315 is fixed, the wear of different positions of the ball 17 will be uneven. At this time, by setting the buffer rod 18, when the corresponding movable mold 22 abuts against the buffer rod 18 or moves away from the buffer rod 18, the size of the space of the first groove 144 below the buffer rod 18 will change. If the space of the first groove 144 below the buffer rod 18 becomes smaller, the gas in the first groove 144 enters the outside through the channel 146, and the airflow flowing in the channel 146 will drive the ball 17 to rotate; if the space of the first groove 144 below the buffer rod 18 becomes larger, the outside gas enters the first groove 144 through the channel 146, and the airflow flowing in the channel 146 will also drive the ball 17 to rotate, which can balance the wear of the outer wall of the ball 17 and improve the service life of the ball 17.

[0055] Reference Figure 2 、 Figure 8To fully open the corresponding movable mold 22 directly after the ejector block 33 unlocks the latch 252, two force-applying blocks 35 are fixed to the movable mold 22. The two force-applying blocks 35 are located on either side of the extension rod 253. Two straight slots 334 are defined on the top surface of the ejector block 33. A ejector rod 34 is vertically slidably connected to the slots 334. A fourth spring 36 is disposed within the slots 334. The ends of the fourth spring 36 are fixed to the bottom walls of the ejector rod 34 and the slots 334, respectively. When the ejector block 33 moves upward, the two ejector rods 34 first abut against the two force-applying blocks 35, causing the two fourth springs 36 to be compressed. As the ejector block 33 moves upward, the compressed potential energy of the fourth springs 36 gradually increases. Once the ejector block 33 lifts the force-applying blocks, the accumulated elastic potential energy of the fourth springs 36 spreads the corresponding movable mold 22, causing the movable mold 22 to automatically open until it abuts against the first support rod 14 or the second support rod 15.

[0056] The implementation principle of a shoe sole production equipment of the embodiment of the present application is as follows: the injection molding device 13 injects the molten injection molding material into the injection port 24 of the corresponding sole mold 2, then the turntable 12 rotates one circle, the sole is cooled and formed, and then the operator opens the movable mold 22 to remove the sole, and then closes the movable mold 22 again. This sole mold 2 will follow the rotation of the turntable 12 and pass through the injection molding device 13 again, and be re-filled and injection-molded. The operator only needs to work at one station, constantly taking out the soles formed by different sole molds 2 and then closing the movable mold 22, which can greatly improve the production efficiency of the sole. At the same time, the corresponding unlocking device 3 can automatically unlock the locking device 25 and flip the corresponding movable mold 22, so that the movable mold 22 closed with the fixed mold 21 is automatically in an open state.

[0057] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
