Description

Technical Field

[0001] This utility model relates to the field of glass bottle production, and in particular to a buffer structure for a bottle disposal rack. Background Technology

[0002] In automated glass bottle production lines, the rapid sorting and removal of defective glass bottles is crucial for ensuring production efficiency and product quality. Therefore, discard racks, as a common device for collecting defective glass bottles, are typically integrated into one side of the inspection station to receive and transfer rejected bottles. Existing discard rack designs usually include a discard opening on one side and a connecting groove on the other. The discard opening is located near the top of the rack (to accommodate the height of the conveyor belt and facilitate the entry of defective bottles), while the connecting groove is near the bottom (because defective bottles fall to the bottom of the rack under gravity, the groove helps receive them). The connecting groove connects to an external discard channel, guiding the defective bottles to the external collection area via tilting or gravity. Specifically, after a defective bottle enters through the discard opening, it slides along the internal space of the rack and eventually passes through the connecting groove into the discard channel, where it is disposed of in the designated external area, completing the disposal process.

[0003] Because the bottom surface inside the bottle disposal rack is usually a rigid planar structure, when a glass bottle enters through the disposal opening, its falling process lacks effective cushioning, causing the glass bottle to directly impact the bottom surface inside the bottle disposal rack with a large impact force. As the bottom surface inside the bottle disposal rack is subjected to instantaneous impact load for a long time, local stress concentration occurs, which accelerates the generation of fatigue cracks on the material surface, causing the bottom surface inside the bottle disposal rack to break through. Finally, the breakthrough will cause defective glass bottles to spill out, causing inconvenience to use. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a buffer structure for a bottle disposal rack. The purpose is to solve the problem that when a glass bottle enters through the disposal opening, its descent lacks effective buffering, causing the bottle to directly impact the bottom surface inside the rack with significant force. Because the bottom surface inside the rack is subjected to constant instantaneous impact loads, localized stress concentration accelerates the formation of fatigue cracks on the material surface, eventually causing the bottom surface inside the rack to puncture. Ultimately, the puncture allows defective glass bottles to spill out, resulting in inconvenience for users.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A buffer structure for a bottle disposal rack includes a base and a bottle disposal rack body disposed on top of the base. The bottle disposal rack body has a bottle disposal cavity inside. One side of the bottle disposal rack body has a bottle disposal opening communicating with the bottle disposal cavity, and the other side of the bottle disposal rack body has a connecting groove communicating with the bottle disposal cavity. The connecting groove communicates with an external bottle disposal channel. One side of the bottle disposal cavity has a bottle guide surface, and one end of the bottle guide surface has a feeding surface near the bottle disposal opening. One side of the bottle guide surface has a movable plate, forming a passage gap between one side of the movable plate and the other side of the bottle disposal cavity, with the passage gap facing the bottom surface of the bottle disposal cavity. This allows the movable plate to be positioned between the bottle disposal opening and the connecting groove. The top of the movable plate has a buffer plate, which is elastic. The top of the buffer plate has a guide slope, which is inclined towards the passage gap.

[0007] When defective glass enters the discard bottle opening, the feeding surface, being close to the opening, receives the bottles sliding in from the conveyor belt. This causes the bottles to move towards the movable plate after passing the guide surface. Because the movable plate has an elastic buffer plate at its top, the bottles, guided by the guide surface, first impact the buffer plate, rather than directly striking the bottom of the discard cavity. The elastic material of the buffer plate absorbs the impact energy through its deformation, while the guide ramp at its top forces the bottles to slide along the ramp through the gap, converting the remaining impact force into lateral sliding kinetic energy. This further weakens the impact on the bottom of the discard cavity, ultimately resulting in a low-impact contact with the bottom of the cavity before being discharged from the connecting groove into the external discard channel. This completely avoids the bottles impacting the bottom of the cavity with significant force, reducing the instantaneous impact load on the bottom and minimizing the risk of the cavity's bottom being punctured.

[0008] Furthermore, in this application, the top of the movable plate is provided with an installation groove, the top of the installation groove is provided with multiple locking holes, the bottom of the buffer plate is provided with multiple locking posts, the locking posts are elastic, and the multiple locking posts are respectively engaged with the multiple locking holes.

[0009] The mounting groove at the top of the movable plate is used to position the buffer plate. Multiple elastic pins at the bottom of the buffer plate correspond one-to-one with the locking holes in the mounting groove. When the buffer plate is inserted into the mounting groove, the pins are squeezed and undergo elastic deformation. Then the pins recover their deformation and lock into the locking holes, forming a mechanical lock. This process utilizes the deformation and reset characteristics of elastic materials to achieve rapid fixation of the buffer plate and the movable plate.

[0010] Furthermore, in this application, the bottom of the movable plate is provided with a disassembly groove, which is connected to the mounting groove.

[0011] When it is necessary to disassemble the buffer plate, the bottom groove insertion tool can be removed and pressed against the buffer plate from bottom to top, so that the pushing force is greater than the elasticity of the locking pin and the locking hole, forcing the locking pin to disengage from the mechanical locking state of the locking hole. This design uses the external force assistance of the tool to act directly on the bottom of the buffer plate, reducing the force required to manually pull out the buffer plate.

[0012] Furthermore, in this application, one end of the bottle rack body is provided with a first connecting slot, the movable plate is slidably engaged with the bottle guide surface, one end of the movable plate is provided with a first extension seat, one side of the first extension seat extends out of the first connecting slot, the other end of the movable plate is provided with a second extension seat, the other end of the bottle rack body is provided with a second connecting slot, and one side of the second extension seat extends out of the second connecting slot.

[0013] Furthermore, in this application, one end of the bottle rack body is provided with a fixed base, one side of the fixed base is provided with a movable groove, the movable groove is connected to the first connecting slot, one side of the first extension base is inserted into the movable groove, the top of the first extension base is provided with a plurality of first limiting holes, the top of the fixed base is provided with a plurality of second limiting holes, the second limiting holes are connected to the movable groove, a first limiting post is inserted into the second limiting hole, and the first limiting post is inserted into the adjacent first limiting hole.

[0014] Furthermore, in this application, a first limiting plate is provided on one side of the first extension seat, the size of the first limiting plate is larger than the movable groove, and the first limiting plate is located on one side of the fixed seat.

[0015] Furthermore, in this application, a fixing plate is provided laterally at the other end of the bottle rack body. The fixing plate is located above the second connecting slot, so that one side of the second extension seat is located below the fixing plate. A plurality of third limiting holes are provided inside the fixing plate, and a plurality of fourth limiting holes are provided on the top of the second extension seat. A second limiting post is inserted into the third limiting hole, and the second limiting post is inserted into the adjacent fourth limiting hole.

[0016] Furthermore, in this application, a second limiting plate is vertically provided on one side of the fixing plate, and the second extension seat abuts against the second limiting plate.

[0017] Furthermore, in this application, the top of the bottle opening is provided with multiple mounting seats, the bottom of the mounting seats is provided with a splash guard, one end of the splash guard is close to the feed surface, and the splash guard is deformable and elastic.

[0018] Furthermore, in this application, multiple mounting bases are installed at equal intervals on top of the bottle disposal opening, such that the splash guards of the multiple mounting bases cover the bottle disposal opening.

[0019] This invention has the following beneficial effects: When defective glass enters the discard bottle opening, the feeding surface is close to the opening and thus receives the defective glass bottles sliding in from the conveyor belt. After passing the guide surface, the defective glass bottles move towards the movable plate. Since the top of the movable plate is equipped with an elastic buffer plate, the defective glass bottles, guided by the guide surface, first impact the top buffer plate of the movable plate, rather than directly impacting the bottom surface of the discard bottle cavity. The elastic material of the buffer plate absorbs the impact energy through its own deformation. At the same time, the guide slope at its top forces the defective glass bottles to slide along the guide slope through the gap, converting the remaining impact force into lateral sliding kinetic energy, further weakening the impact intensity on the bottom surface of the discard bottle cavity. Finally, the bottles contact the bottom surface of the discard bottle cavity with a low impact state and are then discharged from the external discard bottle channel through the connecting groove. This completely avoids the defective glass bottles impacting the bottom surface of the discard bottle cavity with a large impact force, reducing the instantaneous impact load on the bottom of the discard bottle cavity and reducing the risk of the bottom surface of the discard bottle cavity being punctured.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] Reference Figures 1-9 In some specific embodiments, a buffer structure for a bottle disposal rack includes a base 1 and a bottle disposal rack body 2 disposed on top of the base 1. The bottle disposal rack body 2 has a bottle disposal cavity 4 inside. One side of the bottle disposal rack body 2 has a bottle disposal opening 3 communicating with the bottle disposal cavity 4. The other side of the bottle disposal rack body 2 has a connecting groove 6 communicating with the bottle disposal cavity 4. The connecting groove 6 communicates with an external bottle disposal channel. One side of the bottle disposal cavity 4 is formed with a bottle guide surface 31. One end of the bottle guide surface 31 is provided with a feeding surface 32. The feeding surface 32 is close to the bottle disposal opening 3. One side of the bottle guide surface 31 is provided with a movable plate 7, which forms a passage gap 5 between one side of the movable plate 7 and the other side of the bottle disposal cavity 4. The passage gap 5 faces the bottom surface of the bottle disposal cavity 4, so that the movable plate 7 is located between the bottle disposal opening 3 and the connecting groove 6. The top of the movable plate 7 is provided with a buffer plate 9. The buffer plate 9 is elastic. The top of the buffer plate 9 is formed with a guide slope 30, which is inclined towards the passage gap 5.

[0035] Through the above technical solution, when defective glass enters the discard bottle opening 3, the feeding surface 32 is close to the discard bottle opening 3, so the feeding surface 32 is used to receive the defective glass bottles sliding in from the conveyor belt. This allows the defective glass bottles to move towards the movable plate 7 after passing the guide surface 31. Since the top of the movable plate 7 is provided with an elastic buffer plate 9, the defective glass bottles, after being guided by the guide surface 31, first impact the top buffer plate 9 of the movable plate 7, rather than directly impacting the bottom surface of the discard bottle cavity 4. The elastic material (such as rubber or polyurethane) of the buffer plate 9 absorbs the impact through its own deformation. It absorbs impact energy, and at the same time, the guide slope 30 at the top forces the defective glass bottle to slide along the direction of the guide slope 30 through the gap 5, converting the remaining impact force into lateral sliding kinetic energy, further weakening the impact intensity on the bottom surface of the bottle disposal cavity 4, and finally contacting the bottom surface of the bottle disposal cavity 4 in a low impact state, and then being discharged from the external bottle disposal channel through the connecting groove 6. This completely avoids the defective glass bottle from colliding with the bottom surface of the bottle disposal cavity 4 with a large impact force, reduces the instantaneous impact load on the bottom of the bottle disposal cavity 4, and reduces the risk of the bottom surface of the bottle disposal cavity 4 being punctured.

[0036] It should be noted that the bottle disposal opening 3 is located near the top of the bottle disposal rack body 2. This is to facilitate the adaptation to the height of the conveyor belt so that defective glass bottles can enter. The connecting groove 6 is located near the bottom of the bottle disposal cavity 4. (Due to the limitations of the production environment, the bottle disposal rack body 2 is usually set on the side of the conveyor or on the floor of the production workshop, while the bottle disposal channel runs through the wall of the production workshop and extends to the external collection area, i.e., it is set at an angle towards the collection area. Therefore, the connecting groove 6 cannot be located on the bottom of the bottle disposal cavity 4.) Defective glass bottles will fall to the bottom of the bottle disposal cavity 4 under the action of gravity. Therefore, the connecting groove 6 can easily receive the fallen glass bottles.

[0037] In addition, refer to Figures 8-9 In some specific embodiments, the top of the movable plate 7 is provided with an installation groove 8, the top of the installation groove 8 is provided with multiple locking holes 11, and the bottom of the buffer plate 9 is provided with multiple locking posts 12. The locking posts 12 are elastic, and the multiple locking posts 12 are respectively engaged with the multiple locking holes 11.

[0038] Through the above technical solution, since the buffer plate 9 needs to be constantly impacted by defective glass bottles, the buffer plate 9 is prone to elastic failure or damage after long-term use. Therefore, when the damaged buffer plate 9 needs to be replaced, the mounting groove 8 opened on the top of the movable plate 7 is used to position the buffer plate 9. The multiple elastic locking posts 12 at the bottom of the buffer plate 9 correspond one-to-one with the locking holes 11 in the mounting groove 8. When the buffer plate 9 is inserted into the mounting groove 8, the locking posts 12 are squeezed and undergo elastic deformation (such as the shrinkage or bending of rubber or polyurethane materials). Then the locking posts 12 recover their deformation and lock into the locking holes 11, forming a mechanical lock. This process utilizes the deformation and reset characteristics of elastic materials to achieve rapid fixation of the buffer plate 9 and the movable plate 7.

[0039] In addition, during implementation, the size of the locking post 12 needs to be slightly larger than that of the locking hole 11.

[0040] Reference Figures 8-9 In some specific embodiments, the bottom of the movable plate 7 is provided with a disassembly groove 10, which is connected to the mounting groove 8.

[0041] With the above technical solution, when it is necessary to disassemble the buffer plate 9, a tool (such as a special push rod) can be inserted into the bottom groove 10 to press the buffer plate 9 from bottom to top, so that the pushing force is greater than the elasticity of the locking post 12 and the locking hole 11, forcing the locking post 12 to disengage from the mechanical locking state of the locking hole 11. This design uses the external force of the tool to act directly on the bottom of the buffer plate 9, reducing the force required when manually pulling the buffer plate 9.

[0042] Reference Figures 1-7In some specific embodiments, a first connecting slot 17 is provided at one end of the bottle rack body 2, the movable plate 7 is slidably engaged with the bottle guide surface 31, a first extension seat 13 is provided at one end of the movable plate 7, one side of the first extension seat 13 extends out of the first connecting slot 17, a second extension seat 15 is provided at the other end of the movable plate 7, a second connecting slot 22 is provided at the other end of the bottle rack body 2, and one side of the second extension seat 15 extends out of the second connecting slot 22.

[0043] With the above technical solution, the first extension seat 13 and the second extension seat 15 at both ends of the movable plate 7 are respectively inserted into the first connecting slot 17 and the second connecting slot 22 of the bottle rack body 2 to form a sliding fit. Thus, when the movable plate 7 needs to be disassembled, the movable plate 7 is pulled out from the first connecting slot 17, the first extension seat 13 disengages from the first connecting slot 17, and the movable plate 7 slides along the bottle guide surface 31, so that the second extension seat 15 disengages from the second connecting slot 22, so that the movable plate 7 or the buffer plate 9 can be disassembled when it needs to be replaced.

[0044] Reference Figures 5-7 In some specific embodiments, a fixed base 18 is provided at one end of the bottle rack body 2. A movable groove 19 is provided on one side of the fixed base 18. The movable groove 19 is connected to the first connecting slot 17. One side of the first extension base 13 is inserted into the movable groove 19. A plurality of first limiting insertion holes 16 are provided on the top of the first extension base 13. A plurality of second limiting insertion holes 20 are provided on the top of the fixed base 18. The second limiting insertion holes 20 are connected to the movable groove 19. A first limiting insertion post 21 is inserted into the second limiting insertion hole 20. The first limiting insertion post 21 is inserted into the adjacent first limiting insertion hole 16.

[0045] With the above technical solution, when the new movable plate 7 is installed, the movable plate 7 slides in along the guide bottle surface 31, so that the second extension seat 15 is inserted into the second connecting slot 22, the first extension seat 13 is inserted into the first connecting slot 17, the first limiting plug 21 passes through the first limiting plug hole 16 and is inserted into the adjacent second limiting plug hole 20, thereby limiting the lateral position of the first extension seat 13 and preventing the movable plate 7 from shifting when the buffer plate 9 is subjected to impact force.

[0046] Reference Figures 5-7 In some specific embodiments, a first limiting plate 14 is provided on one side of the first extension seat 13. The size of the first limiting plate 14 is larger than that of the movable groove 19, and the first limiting plate 14 is located on one side of the fixed seat 18.

[0047] With the above technical solution, when the first extension seat 13 is inserted into the movable slot 19, since the size of the first limiting plate 14 is larger than the movable slot 19, the first limiting plate 14 will abut against one side of the fixed seat 18, thereby preventing the first extension seat 13 from being inserted too far into the movable slot 19, and thus positioning the installation position of the movable plate 7.

[0048] Reference Figures 1-5 In some specific embodiments, a fixing plate 24 is provided horizontally at the other end of the bottle rack body 2. The fixing plate 24 is located above the second connecting slot 22, so that one side of the second extension seat 15 is located below the fixing plate 24. Multiple third limiting holes 26 are provided inside the fixing plate 24, and multiple fourth limiting holes 23 are provided on the top of the second extension seat 15. A second limiting post 27 is inserted into the third limiting hole 26, and the second limiting post 27 is inserted into the adjacent fourth limiting hole 23.

[0049] With the above technical solution, when the movable plate 7 slides in along the guide bottle surface 31, the second extension seat 15 is inserted into the second connecting slot 22, and the first extension seat 13 is inserted into the first connecting slot 17. The second limiting pin 27 passes through the third limiting hole 26 and is inserted into the adjacent fourth limiting hole 23, thereby limiting the lateral position of the second extension seat 15 and further improving the stability of the movable plate 7.

[0050] Reference Figures 1-5 In some specific embodiments, a second limiting plate 25 is vertically provided on one side of the fixing plate 24, and the second extension seat 15 abuts against the second limiting plate 25.

[0051] With the above technical solution, when the second extension seat 15 is inserted through the second connecting slot 22 and located below the fixing plate 24, a second limiting plate 25 is vertically provided on one side of the fixing plate 24. The second extension seat 15 abuts against the second limiting plate 25, thereby preventing the second extension seat 15 from extending too far out of the second connecting slot 22, and further positioning the installation position of the movable plate 7.

[0052] Reference Figures 1-2 In some specific embodiments, the top of the bottle opening 3 is provided with multiple mounting seats 28, and the bottom of the mounting seat 28 is provided with a splash guard 29. One end of the splash guard 29 is close to the feed surface 32, and the splash guard 29 is deformable and elastic.

[0053] With the above technical solution, when the defective glass bottle slides into the discard bottle opening 3, the defective glass bottle may break after colliding with the buffer plate 9, resulting in glass fragments. The glass fragments will splash and bounce outward due to inertia. At this time, the anti-splash strip 29 forms a flexible barrier through its own elasticity and deformation (such as rubber or silicone), absorbs the splash kinetic energy and changes its direction of movement, thereby preventing the glass fragments from flying out of the discard bottle opening 3.

[0054] Reference Figures 1-2 In some specific embodiments, multiple mounting bases 28 are installed at equal intervals on the top of the bottle opening 3, so that the splash guards 29 of the multiple mounting bases 28 cover the bottle opening 3.

[0055] Through the above technical solution, multiple mounting bases 28 are fixed to the top of the bottle opening 3 in an equally spaced manner, so that the splash guards 29 at the bottom of each mounting base 28 are connected to each other or partially overlap to form a continuous elastic barrier, thereby completely covering the entrance area of ​​the bottle opening 3 and preventing glass fragments from splashing out from the gaps.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
