Abstract
Description
Technical Field
[0001] This invention relates to the field of glass bottle production, and in particular to an angle-adjustable air-blowing glass bottle rejection device. Background Technology
[0002] On glass bottle production lines, glass bottles may tip over due to collisions, conveyor belt vibrations, or their own unstable center of gravity. If these tipped bottles are not removed in time, they will interfere with subsequent packaging processes, causing equipment jams, product contamination, or even production line shutdowns, seriously affecting production efficiency and product quality. Currently, the most commonly used device in the industry is the air-blowing rejection device. Its principle is that after a tipped bottle is detected by a photoelectric sensor or vision system, the control system controls the air-blowing rejection device to spray compressed air from the jet nozzles of the air-blowing rejection device, forming a pulse airflow that blows the tipped bottle away from the conveyor belt and into the waste collection device.
[0003] However, when handling small, irregularly shaped glass bottles that are not cylindrical (such as square, rectangular, or flat bottles), after the bottles tip over, the surface with the largest bottom area (usually the largest side) lies flat against the conveyor belt. This results in a large contact area between the bottle and the conveyor belt. Furthermore, due to their small size (but heavy weight), the overall height after tipping over is much lower than that of a standard upright bottle. Existing air-blowing rejection devices are typically designed based on standard round or conventionally sized bottles, with their air jets arranged at equal intervals in a vertical manner. When dealing with the tipping of these small, irregularly shaped glass bottles, this arrangement results in a fixed spacing between the air jets and a predominantly parallel airflow direction. Only a few (or even just one) of the air jets can barely cover the low profile of the tipped bottle, while the airflow from the remaining jets simply passes over the top of the bottle. This drastically reduces the number of effective air jets, resulting in insufficient total force. The system cannot generate an effective torque to slide the bottle, often only causing a slight sway or a very short translation in place, making reliable rejection impossible and causing inconvenience. Summary of the Invention
[0004] To solve the above-mentioned technical problems, the present invention provides an angle-adjustable air-blowing glass bottle rejection device, which aims to solve the technical problem that existing air-blowing rejection devices cannot remove small-sized irregularly shaped glass bottles from the conveyor belt when they are being inverted.
[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: An angle-adjustable blowing-type glass bottle rejection device includes a conveyor frame with a conveyor belt at the top. A rejection section is located on one side of the conveyor frame, and a waste collection device is located on the other side. The rejection section includes a base on one side of the conveyor frame, and a jet seat is located at the top of the base. Multiple first and second jet ports are located on one side of the jet seat, with the second jet ports positioned above the first jet ports. An air inlet valve is located outside the jet seat, communicating with the interior of the jet seat. The first and second jet ports communicate with the interior of the jet seat. Multiple mounting seats are located on one side of the jet seat, each mounting seat being located on one side of a plurality of second jet ports. A movable cavity communicating with adjacent second jet ports is opened inside each mounting seat. A guide head is rotatably connected inside the movable cavity, and a guide cavity communicating with the movable cavity is opened inside the guide head. One end of the guide head has a guide port communicating with the guide cavity.
[0006] Before rejecting small, irregularly shaped glass bottles, the operator manually rotates the air guide head, adjusting the direction of its nozzle, based on the observed posture of the inverted bottle (e.g., the wide side of a flat bottle touching the ground). This causes the airflow to exit at a downward angle. This downward-sloping airflow acts on the top or upper side edge of the inverted bottle. Because this force is applied far from the bottle's center of gravity, it immediately generates a torque that causes the bottle to roll around its contact edge, thus breaking the contact between the bottle and the conveyor belt. The jet nozzle maintains a horizontal airflow, allowing small, irregularly shaped glass bottles to slide laterally along the conveyor belt. The horizontal airflow immediately acts on the side of the small, irregularly shaped glass bottles, providing a continuous sliding thrust parallel to the conveyor belt. At this point, the small, irregularly shaped glass bottles have changed from a flat, difficult-to-move state to an easy-to-slide state with one end slightly raised and friction greatly reduced. Under the continuous push of the horizontal airflow, the small, irregularly shaped glass bottles can smoothly slide laterally away from the conveyor belt and accurately fall into the waste collection device, effectively solving the problems of small, irregularly shaped bottles being difficult to remove due to their low height and adherence, and the second jet nozzle being unable to cover small, irregularly shaped bottles.
[0007] Furthermore, in this application, a movable slider is slidably connected to one side of the air guide head, a transmission gear is provided on one side of the movable slider, a transmission bar is slidably connected to one side of the jet seat, a transmission tooth is provided on one side of the transmission bar, and the transmission gear meshes with the transmission tooth.
[0008] When switching between different shaped glass bottles (e.g., from large to small), operators do not need to rotate each air guide head individually. They only need to move the transmission bar. The linear motion of the transmission bar is transmitted to the meshing transmission gear through the transmission teeth on its side, thus converting the linear motion into the rotational motion of the gear. The movable slider is slidably connected to its corresponding air guide head, so when the transmission gear rotates, it drives the movable slider to move, thereby causing the air guide head to rotate synchronously and at the same angle around the axis of its movable cavity. This mechanical linkage structure ensures that all air guide heads on multiple second air nozzles can maintain a consistent angle of deflection. Whether adjusted to tilt downwards to concentrate the flipping torque or adjusted to be horizontal to provide uniform thrust, the global setting can be completed in one operation, avoiding the tedious and time-consuming manual adjustment of each one in the traditional way. This allows the adjustment speed of the rejection section to be highly matched with the production cycle requirements when switching production lines to produce different glass bottles, reducing downtime for adjustment.
[0009] Furthermore, in this application, a movable groove is provided on one side of the air guide head, the movable slider slides in cooperation with the adjacent movable groove, and a return spring is provided inside the movable groove, one end of the return spring being connected to the movable slider.
[0010] When the operator moves the transmission bar, power is transmitted through the meshing of the transmission teeth and the transmission gear. The rotation of the transmission gear drives the movable slider connected to it to move. Since the movable slider is nested in and slides within the movable groove on one side of the air guide head, it slides along the trajectory of the movable groove, thereby driving the air guide head to rotate precisely around its own axis, achieving angle adjustment. The return spring provides a gentle elastic resistance, making the operation feel smoother and helping to eliminate the tiny gaps between the transmission teeth and the transmission gear. This makes the rotation response of the air guide head more direct, thereby improving the accuracy of the angle setting. It effectively prevents the transmission gear meshing from loosening or the angle from spontaneously shifting due to equipment vibration, ensuring the long-term maintenance of the air guide head's set angle.
[0011] Furthermore, in this application, a drive seat is provided on one side of the jet seat, and a drive cylinder is provided on one side of the drive seat. The piston rod of the drive cylinder is connected to one end of the transmission bar.
[0012] Furthermore, in this application, a guide seat is provided on one side of the jet seat, a transmission groove is provided on one side of the guide seat, and the other side of the transmission bar slides in cooperation with the transmission groove.
[0013] Furthermore, in this application, the interior of the movable cavity is provided with a sealing gasket frame, the sealing gasket frame is elastic, and the air guide head passes through the interior of the sealing gasket frame, so that the air guide head abuts against the interior of the sealing gasket frame.
[0014] Furthermore, in this application, the top of the base is provided with an adjusting slider, the other side of the jet seat is provided with an adjusting seat, the bottom of the adjusting seat is provided with an adjusting groove, the adjusting groove is slidably engaged with the adjusting slider, and one side of the adjusting seat is provided with a first locking hole communicating with the adjusting groove, the first locking hole is internally threaded with a first locking bolt, and the first locking bolt abuts against the adjusting slider.
[0015] Furthermore, in this application, a lifting seat is provided on the other side of the jet seat, and a lifting groove is provided inside the lifting seat. An adjusting rod is vertically provided on the top of the adjusting seat, and the lifting groove and the adjusting rod are slidably engaged. A second locking hole is provided on one side of the lifting seat, and the second locking hole is connected to the lifting groove. A second locking bolt is threaded into the second locking hole, and the second locking bolt abuts against the adjusting rod.
[0016] Furthermore, in this application, the waste collection device includes a collection box located on the other side of the conveyor frame, and a collection cavity is provided on one side of the collection box, the collection cavity being connected to an external recycling channel.
[0017] Furthermore, in this application, the top two sides of the conveyor frame are provided with protective railings, and a connecting groove is provided on one side of the protective railing. The connecting groove is located between the jet seat and the waste collection device.
[0018] The present invention has the following beneficial effects: Before rejecting small, irregularly shaped glass bottles, the operator manually rotates the air guide head, adjusting the direction of its nozzle, based on the observed posture of the inverted bottle (e.g., the wide side of a flat bottle touching the ground). This causes the airflow to exit at a downward angle. This downward-sloping airflow acts on the top or upper side edge of the inverted bottle. Because this force is applied far from the bottle's center of gravity, it immediately generates a torque that causes the bottle to roll around its contact edge, thus breaking the contact between the bottle and the conveyor belt. The jet nozzle maintains a horizontal airflow, allowing small, irregularly shaped glass bottles to slide laterally along the conveyor belt. The horizontal airflow immediately acts on the side of the small, irregularly shaped glass bottles, providing a continuous sliding thrust parallel to the conveyor belt. At this point, the small, irregularly shaped glass bottles have changed from a flat, difficult-to-move state to an easy-to-slide state with one end slightly raised and friction greatly reduced. Under the continuous push of the horizontal airflow, the small, irregularly shaped glass bottles can smoothly slide laterally away from the conveyor belt and accurately fall into the waste collection device, effectively solving the problems of small, irregularly shaped bottles being difficult to remove due to their low height and adherence, and the second jet nozzle being unable to cover small, irregularly shaped bottles.

[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0028] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the 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, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.
[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows for communication; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0030] In existing technologies, when processing small, non-cylindrical irregularly shaped glass bottles 400 (such as square bottles, rectangular bottles, flat bottles, etc.), after the bottles tip over, the structural surface with the largest bottom area (usually the largest side surface) of these bottles lies flat against the conveyor belt 110. This results in a large contact area between the bottle and the conveyor belt 110, and because these bottles are small in size (but heavy), their overall height after tipping over is much lower than that of standard upright bottles. Existing air-blowing rejection devices are typically designed based on optimizations for standard round bottles or conventionally sized bottles, and their air jets use equal-sized nozzles. The arrangement of the air jets in a vertical, spaced-out manner results in a problem when dealing with the aforementioned small, irregularly shaped glass bottles (400mm diameter). Because the spacing between the air jets is fixed and the airflow direction is predominantly parallel, only a few (or even just one) of the air jets can barely cover the low profile of the inverted bottle. The airflow from the remaining jets simply passes over the top of the bottle, drastically reducing the number of effective jets and resulting in insufficient total force. This makes it impossible to generate an effective torque to slide the bottle, often only causing a slight wobbling or very short displacement of the bottle in place, making reliable removal difficult and inconvenient.
[0031] Those skilled in the art can easily conceive of using a cylinder to push and remove inverted irregularly shaped glass bottles based on the aforementioned technical problems. The principle of the cylinder is that the piston rod extends linearly to directly push the inverted irregularly shaped glass bottle out of the conveyor belt 110. However, in actual high-speed glass bottle production lines, this solution has a fundamental flaw. This is because the cylinder's operation cycle requires a certain amount of time, and its cycle of extension and retraction is usually difficult to be less than 0.5 seconds. In modern high-speed production lines, the spacing between glass bottles in the conveyor is small, usually only accommodating the interval of two inverted bottles. The slow operating speed of the cylinder can easily cause action delays when inverted bottles occur continuously or when high-frequency removal is required, leading to missed removal or interference with subsequent normal bottles, and making it impossible to synchronize with the high-speed production line. However, by using compressed air as a medium, the response time of the airflow jet controlled by the removal unit can reach the millisecond level, which can perfectly match the high-speed production rhythm, achieving instantaneous and precise trigger removal without mechanical inertia delay.
[0032] Reference Figures 1-7 In some specific embodiments, an angle-adjustable blowing-type glass bottle rejection device includes a conveyor frame 100, a conveyor belt 110 at the top of the conveyor frame 100, a rejection section 200 on one side of the conveyor frame 100, and a waste collection device 300 on the other side of the conveyor frame 100. The rejection section 200 includes a base 240 located on one side of the conveyor frame 100, a jet seat 210 at the top of the base 240, a plurality of first jet ports 211 and second jet ports 212 on one side of the jet seat 210, the second jet ports 212 being located above the first jet ports 211, and an air inlet valve 260 on the outside of the jet seat 210. The air intake valve 260 is connected to the interior of the jet seat 210. The first jet port 211 and the second jet port 212 are connected to the interior of the jet seat 210. A plurality of mounting seats 220 are provided on one side of the jet seat 210. The plurality of mounting seats 220 are respectively located on one side of the plurality of second jet ports 212. The interior of the mounting seat 220 is provided with a movable cavity 221 that connects to the adjacent second jet ports 212. A guide head 222 is rotatably connected inside the movable cavity 221. The interior of the guide head 222 is provided with a guide cavity 224 that connects to the movable cavity 221. One end of the guide head 222 is provided with a guide port 223 that connects to the guide cavity 224.
[0033] Through the above technical solution, before removing small-sized irregularly shaped glass bottles 400, the operator manually rotates the air guide head 222 and adjusts the orientation of its air guide nozzle 223 based on the observed posture of the inverted small-sized irregularly shaped bottle (e.g., the wide side of a flat bottle touching the ground). This causes the airflow ejected from the air guide nozzle 223 to be ejected at a downward angle. This downward-sloping airflow acts on the top or upper side edge of the inverted small-sized irregularly shaped glass bottle 400. Since the point of application of this force is far from the center of gravity of the small-sized irregularly shaped glass bottle 400, it immediately generates a torque that causes the small-sized irregularly shaped glass bottle 400 to roll around its contact edge, thereby breaking the contact between the small-sized irregularly shaped glass bottle 400 and the conveyor belt 110. The jet nozzle 211 maintains horizontal jet propulsion, causing the small-sized irregularly shaped glass bottle 400 to slide laterally along the conveyor belt 110. The horizontal airflow immediately acts on the side of the small-sized irregularly shaped glass bottle 400, providing a continuous sliding thrust parallel to the conveyor belt 110. At this time, the small-sized irregularly shaped glass bottle 400 has changed from a flat and difficult-to-move state to an easy-to-slide state with one end slightly raised and friction greatly reduced. Under the continuous push of the horizontal airflow, the small-sized irregularly shaped glass bottle 400 can smoothly slide laterally away from the conveyor belt 110 and accurately fall into the waste collection device 300, effectively solving the problem that the small-sized irregularly shaped bottle 400 is difficult to remove due to its low height and close adhesion, and that the second jet nozzle 212 cannot cover the small-sized irregularly shaped bottle 400.
[0034] Furthermore, before removing the large-sized irregularly shaped glass bottle 410, the operator should not adjust the air guide head 222 to be angled downwards, but should rotate it to a horizontal spray state parallel to the first jet nozzle 211. This is because the large-sized irregularly shaped glass bottle 410 has a large mass and a high center of gravity. If the downward spray is still used, the concentrated airflow will strongly impact the lower part of the large-sized irregularly shaped glass bottle 410 after it has been tilted. Due to the low point of impact, it is impossible to effectively utilize the overall height of the large-sized irregularly shaped glass bottle 410 to form a stable displacement thrust. Instead, it will cause the large-sized irregularly shaped glass bottle 410 to sway in place. The air guide nozzle 223 should also be adjusted to a horizontal direction so that it works in conjunction with the first jet nozzle 211 to form a wider and more uniform continuous airflow zone on the side of the large-sized irregularly shaped glass bottle 410. For the tall large-sized irregularly shaped glass bottle 410, its side area is large, and a sufficiently distributed area of thrust is needed to overcome its greater mass inertia. The horizontal airflow has a wider coverage area and can act on the middle and upper part of the large-sized irregular glass bottle 410 at the same time, providing a continuous and uniform horizontal thrust, which is more conducive to pushing the large-sized irregular glass bottle 410. Thus, the air guide head 222 can be flexibly adapted according to the glass bottle.
[0035] Reference Figures 4-7In some specific embodiments, a movable slider 228 is slidably connected to one side of the air guide head 222, and a transmission gear 229 is provided on one side of the movable slider 228. A transmission bar 234 is slidably connected to one side of the jet seat 210, and a transmission tooth 235 is provided on one side of the transmission bar 234. The transmission gear 229 meshes with the transmission tooth 235.
[0036] With the above technical solution, when it is necessary to change the shape of the glass bottle (e.g., from a large-sized irregular glass bottle 410 to a small-sized irregular glass bottle 400), the operator does not need to rotate each air guide head 222 individually. Instead, they only need to move the transmission bar 234. The linear motion of the transmission bar 234 is transmitted to the meshing transmission gear 229 via the transmission teeth 235 on its side, thus converting the linear motion into the rotational motion of the transmission gear 229. The movable slider 228 is slidably connected to its corresponding air guide head 222, so that when the transmission gear 229 rotates, it drives the movable slider 228 to move. This drives the air guide head 222 to rotate synchronously and at the same angle around the axis of its movable cavity 221. This mechanical linkage structure ensures that all air guide heads 222 on multiple second air outlets 212 can maintain a consistent angle of deflection. Whether adjusted to tilt downward to concentrate the generation of flipping torque or adjusted to be horizontal to provide uniform thrust, the global setting can be completed in one operation, avoiding the tedious and time-consuming manual adjustment of each one in the traditional way. This makes the adjustment speed of the rejection section 200 highly matched with the production cycle requirements when the production line switches to produce different glass bottles, reducing downtime for adjustment.
[0037] Reference Figures 4-7 In some specific embodiments, a movable groove 226 is provided on one side of the air guide head 222, and the movable slider 228 slides in cooperation with the adjacent movable groove 226. A return spring 227 is provided inside the movable groove 226, and one end of the return spring 227 is connected to the movable slider 228.
[0038] Through the above technical solution, when the operator moves the transmission bar 234, power is transmitted through the meshing of the transmission tooth 235 and the transmission gear 229. The rotation of the transmission gear 229 will drive the movable slider 228 connected to it to move. Since the movable slider 228 is nested in the movable groove 226 opened on one side of the air guide head 222 and slides with it, the movable slider 228 will slide along the trajectory of the movable groove 226, thereby driving the air guide head 222 to rotate precisely around its own axis to achieve angle adjustment. The return spring 227 provides a gentle elastic resistance, making the operation feel smoother and helping to eliminate the small gaps between the transmission tooth 235 and the transmission gear 229. This makes the rotation response of the air guide head 222 more direct, thereby improving the accuracy of the angle setting and effectively preventing the transmission gear 229 from loosening or the angle from spontaneously shifting due to equipment vibration. This ensures the long-term maintenance of the set angle of the air guide head 222.
[0039] Reference Figures 4-7 In some specific embodiments, a drive seat 231 is provided on one side of the jet seat 210, and a drive cylinder 232 is provided on one side of the drive seat 231. The piston rod of the drive cylinder 232 is connected to one end of the transmission bar 234.
[0040] Through the above technical solution, when the drive cylinder 232 receives the command and acts, its piston rod performs precise extension and retraction. Since the end of the piston rod of the drive cylinder 232 is directly connected to one end of the transmission bar 234, the linear motion of the piston rod is directly and without delay converted into the linear movement of the transmission bar 234. The movement of the transmission bar 234 then drives the transmission cam 235 and the transmission gear 229 to drive, thereby improving the immediacy of the adjustment of the air guide head 222.
[0041] Reference Figures 4-7 In some specific embodiments, a guide seat 230 is provided on one side of the jet seat 210, and a transmission groove 233 is provided on one side of the guide seat 230. The other side of the transmission bar 234 is slidably engaged with the transmission groove 233.
[0042] With the above technical solution, when the transmission bar 234 moves, the other side of the transmission bar 234 slides into the transmission groove 233, and the movement of the transmission bar 234 is eliminated by lateral swinging, up and down jumping or twisting around its own axis. This allows the transmission convex tooth 235 fixed on the side of the transmission bar 234 to always maintain a precise meshing with the transmission gear 229 with full tooth width and no offset.
[0043] Reference Figures 4-7 In some specific embodiments, the interior of the movable cavity 221 is provided with a sealing gasket frame 225. The sealing gasket frame 225 is elastic, and the air guide head 222 passes through the interior of the sealing gasket frame 225, so that the air guide head 222 abuts against the interior of the sealing gasket frame 225.
[0044] Through the above technical solution, when the air guide head 222 rotates during angle adjustment, the inner wall of the elastic sealing gasket frame 225 undergoes slight elastic deformation, but always remains in contact with the outer edge of the air guide head 222, dynamically filling and sealing the tiny gaps that inevitably exist due to machining tolerances and movement clearances. This ensures that the high-pressure compressed air entering the movable cavity 221 from the second jet port 212 has its flow direction largely restricted, only able to pass through the air guide cavity 224 inside the air guide head 222, and finally be directionally ejected from the air guide port 223. The sealing gasket frame 225 effectively blocks the path of high-pressure airflow leakage from the gap between the rotating shaft of the air guide head 222 and the wall of the movable cavity 221.
[0045] Reference Figures 4-7In some specific embodiments, the top of the base 240 is provided with an adjusting slider 241, the other side of the jet seat 210 is provided with an adjusting seat 242, the bottom of the adjusting seat 242 is provided with an adjusting groove 243, the adjusting groove 243 is slidably engaged with the adjusting slider 241, and one side of the adjusting seat 242 is provided with a first locking hole 244 that communicates with the adjusting groove 243. The first locking hole 244 is internally threaded with a first locking bolt 245, and the first locking bolt 245 abuts against the adjusting slider 241.
[0046] With the above technical solution, when it is necessary to adjust the lateral position of the jet seat 210, the operator first loosens the first locking bolt 245 on the side of the adjusting seat 242. The first locking bolt 245 disengages from the inside of the adjusting groove 243 and disengages from the surface of the adjusting slider 241, thereby releasing the lock on the jet seat 210. At this time, the jet seat 210 can be manually pushed so that it slides on the adjusting slider 241 through the adjusting groove 243 of the adjusting seat 242 until the center line of the jet nozzle array on the jet seat 210 is aligned with the expected rejection point on the conveyor belt 110 (usually the inlet of the waste collection device 300). After the position is determined, the first locking bolt 245 is tightened again, and its end will be firmly pressed against the surface of the adjusting slider 241. The jet seat 210 and the base 240 are rigidly locked in the new adjusted position by the huge static friction force, preventing the position from shifting due to vibration during equipment operation.
[0047] Reference Figures 4-7 In some specific embodiments, a lifting seat 251 is provided on the other side of the jet seat 210. A lifting groove 252 is provided inside the lifting seat 251. An adjusting rod 250 is vertically provided on the top of the adjusting seat 242. The lifting groove 252 and the adjusting rod 250 are slidably engaged. A second locking hole 253 is provided on one side of the lifting seat 251. The second locking hole 253 is connected to the lifting groove 252. A second locking bolt 254 is threaded into the second locking hole 253. The second locking bolt 254 abuts against the adjusting rod 250.
[0048] With the above technical solution, when it is necessary to adjust the height of the jet seat 210, the operator loosens the second locking bolt 254 on the side of the lifting seat 251. The second locking bolt 254 disengages from the second locking hole 253 and the lifting groove 252, and disengages from the surface of the adjusting rod 250, thereby releasing the vertical lock. At this time, the height of the jet seat 210 can be manually adjusted. For example, for small-sized irregularly shaped bottles 400 that are attached low, the jet seat 210 can be lowered appropriately to make the jet nozzle closer to the conveyor belt 110. For large-sized irregularly shaped bottles 410, the jet seat 210 can be raised appropriately to optimize the airflow coverage. After the adjustment is in place, the second locking bolt 254 is tightened, and its end will be firmly pressed against the surface of the adjusting rod 250, using strong friction to lock the jet seat 210 at the set height.
[0049] Reference Figures 1-3 In some specific embodiments, the waste collection device 300 includes a collection box 310 located on the other side of the conveyor frame 100. A collection cavity 311 is provided on one side of the collection box 310, and the collection cavity 311 is connected to an external recycling channel.
[0050] Through the above technical solution, when the rejection unit 200 operates, the inverted bottle, under the action of airflow, crosses the edge of the conveyor belt 110 at a certain lateral speed and falls naturally under the action of gravity. Since the opening of the collection cavity 311 of the collection box 310 is directly facing the direction of rejection, the inverted bottle can fall directly into the collection cavity 311, thus completely separating it from the qualified product flow on the production line. The inverted bottle entering the collection cavity 311 is transported to the designated centralized processing area through the connected external recycling channel under its own gravity. This prevents the risk of the inverted bottle accumulating, rebounding, or being collided with subsequent bottles near the conveyor belt 110 and re-entering the qualified product area. It ensures the smooth operation of the main conveyor line and the stable operation of subsequent packaging processes, and is a key link in realizing fully automatic continuous rejection.
[0051] Reference Figures 1-3 In some specific embodiments, the top two sides of the conveyor frame 100 are provided with guardrails 120, and a connecting groove 130 is provided on one side of the guardrail 120. The connecting groove 130 is located between the jet seat 210 and the waste collection device 300.
[0052] Through the above technical solution, the guardrail 120 is installed along both sides of the top of the conveyor belt 110 to form a continuous sidewall. Its main function is to prevent glass bottles from falling to the side accidentally during the conveying process and to constrain their travel path. A transverse connecting groove 130 is opened in the section where the rejection operation is required. The connecting groove 130 is aligned with the inlet of the air jet and the collection cavity 311 of the waste collection device 300 to facilitate the bottle rejection operation.
