Detailed Implementation
[0027] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0028] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings.

Therefore, they should not be construed as limitations on this utility model.
[0029] 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, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0030] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; 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 embodiment of the invention according to the specific circumstances.
[0031] Please see Figures 1-5 In this embodiment of the utility model, a height adjustment device is provided, which includes a conveyor belt 1, a first rotating roller 2, a second rotating roller 3, a first rotating motor 4, and a first adjusting cylinder 5. The first rotating roller 2 is installed at one end of the conveyor belt 1, and the second rotating roller 3 is installed at the other end of the conveyor belt 1. The first rotating roller 2 has a first rotating groove 21. The output end of the first rotating motor 4 is connected to the rotating groove. The output end of the first adjusting cylinder 5 is detachably installed on the lower end face of the rotating motor.
[0032] The working principle of this embodiment is as follows: By setting up a height adjustment device, the height can be adjusted to the optimal position when inspecting different batches of empty bottles. When the heights of the empty bottle batches being inspected are different, the operator can control the extension or retraction of the first adjusting cylinder 5 to drive the first rotating motor 4 to rise or fall. The end of the conveyor belt 1 connected to the first rotating motor 4 also rises or falls with the first rotating motor 4. When the height of the empty bottle to be inspected is high, the operator drives the first adjusting cylinder 5 to retract, thereby lowering the first rotating motor 4. The end of the conveyor belt 1 connected to the first rotating motor 4 also falls with the first rotating motor 4, thus reducing the height of the empty bottle during transport. When the height of the empty bottle to be inspected is low, the operator drives the first adjusting cylinder 5 to extend, thereby raising the first rotating motor 4. The end of the conveyor belt 1 connected to the first rotating motor 4 also rises with the first rotating motor 4, thus increasing the height of the empty bottle during transport.
[0033] In another embodiment of this invention, to prevent the empty bottles from tipping over during the conveying process, the angle at which the end of the conveyor belt 1 connected to the first rotating motor 4 is raised is no more than 15° above the horizontal plane. The angle at which the end of the conveyor belt 1 connected to the first rotating motor 4 is lowered is also no more than 15° above the horizontal plane.
[0034] Please see Figures 2-3 In this embodiment of the invention, the height adjustment device further includes a housing 6, which is hollow inside. The housing 6 is fitted with the conveyor belt 1, and a guide groove 61 is provided on the upper end surface of the housing 6 to expose the conveyor belt 1. The housing 6 is used to protect the components of the height adjustment device. On the other hand, during production, it can prevent operators from accidentally touching and damaging the components, thus preventing operator injury.
[0035] Please see Figures 2-5 In this embodiment of the present invention, the second rotating roller 3 is provided with a second rotating groove 31, and the second rotating roller 3 is provided with a limiting device 32. The limiting device 32 includes a first bearing sleeve 33 and a connecting shaft 34. The first bearing sleeve 33 is detachably installed in the second rotating groove 31, and the connecting shaft 34 is inserted into the first bearing sleeve 33 and passes through the second rotating groove 31. The connecting shaft 34 is detachably installed in the housing 6.
[0036] The working principle of this embodiment is as follows: The two ends of the connecting shaft 34 are respectively installed on the inner wall of the housing 6. The connection method between the connecting shaft 34 and the housing 6 includes, but is not limited to, threaded connection and slider connection. When the connecting shaft 34 can be threadedly installed inside the housing 6, it can be used to restrict one end of the conveyor belt 1. The other end of the conveyor belt 1 can be raised or lowered by controlling the first pitch cylinder 5.
[0037] Please see Figures 4-5In this embodiment of the utility model, the height adjustment device is provided with a second adjustable cylinder 7, and the output end of the second adjustable cylinder 7 is connected to the connecting shaft 34 to adjust the position of the connecting shaft 34.
[0038] The working principle of this embodiment is as follows: A second bearing sleeve can be installed at the output end of the second adjusting cylinder 7. The second bearing sleeve is sleeved on the connecting shaft 34. The output end of the second adjusting cylinder 7 is connected to the second bearing sleeve. The second bearing sleeve can be raised or lowered by extending or retracting the second adjusting cylinder 7. The second bearing sleeve drives the connecting shaft 34 to rise or fall. The second bearing sleeve drives the conveyor belt 1 to rise or fall.
[0039] Please see Figure 3 and Figure 6 In this embodiment of the present invention, the inner walls of the sleeve 6 near the connecting shaft 34 are respectively provided with sliding grooves 62, and the two ends of the connecting shaft 34 are slidably installed in the sliding grooves 62.
[0040] The working principle of this embodiment is as follows: When the connecting shaft 34 and the housing 6 are connected by a slider, the second adjusting cylinder 7 can extend or retract, thereby changing the position of the connecting shaft 34. The end of the conveyor belt 1 connected to the connecting shaft 34 also rises or falls with the position of the connecting shaft 34, causing the connecting shaft 34 to slide in the groove 62 on the inner wall of the housing 6. Figure 6 As shown, the two ends of the connecting shaft are provided with sliders corresponding to the slide grooves, and the sliders are integrally connected to the two ends of the connecting shaft.
[0041] Specifically, by cooperating with the first adjusting cylinder 5 and the second adjusting cylinder 7, the position of the entire conveyor belt 1 can be adjusted. When the first adjusting cylinder 5 and the second adjusting cylinder 7 extend at the same time, the entire conveyor belt 1 rises. When the first adjusting cylinder 5 and the second adjusting cylinder 7 retract at the same time, the entire conveyor belt 1 descends.
[0042] Please see Figures 1-5 In this embodiment of the invention, the conveyor belt 1 is further provided with a guiding device, which includes a first stop 8 and a second stop 9. The first stop 8 is installed on the left side of the conveyor belt 1, and the second stop 9 is installed on the right side of the conveyor belt 1. The guiding device is used to guide and support the empty bottle, so that the empty bottle is supported on both sides during transmission. When the empty bottle is transmitted on the conveyor belt 1, the first stop 8 abuts against the left side of the empty bottle, and the second stop 9 abuts against the right side of the empty bottle.
[0043] Please see Figures 4-5 In this embodiment of the utility model, the first stop block 8 includes a left guide plate 81, a left slider 82 and a left cylinder 83. The upper end face of the left guide plate 81 is provided with a left guide rail 84. The left slider 82 is slidably mounted on the left guide rail 84. The left cylinder 83 is hinged to the end face of the left guide plate 81. The output end of the left cylinder 83 is connected to the left slider 82. The right end face of the left slider 82 is provided with at least one first limiting groove 85.
[0044] The working principle of this embodiment is as follows: The left side of the conveyor belt 1 is inserted into the first limiting groove 85. When the conveyor belt 1 is conveying a large empty bottle, the left cylinder 83 retracts to drive the left slider 82 to slide on the left guide plate 81. The left slider 82 slides towards the left cylinder 83, and the position of the left slider 82 can be adjusted according to the size of the empty bottle to accommodate the large empty bottle. Conversely, when the conveyor belt 1 is conveying a small empty bottle, the left cylinder 83 extends to drive the left slider 82 to slide on the left guide plate towards the conveyor belt 1 to accommodate the small empty bottle.
[0045] Please see Figures 4-5 In this embodiment of the present invention, the second stop block 9 includes a right guide plate 91, a right slider 92 and a right cylinder 93. The upper end face of the right guide plate 91 is provided with a right guide rail 94. The right slider 92 is slidably mounted on the right guide rail 94. The right cylinder 93 is hinged to the end face of the right guide plate 91. The output end of the right cylinder 93 is connected to the right slider 92. The right end face of the right slider 92 is provided with at least one second limiting groove 95.
[0046] The working principle of this embodiment is as follows: The right side of the conveyor belt 1 is inserted into the second limiting groove 95. When the conveyor belt 1 is conveying a large empty bottle, the right cylinder 93 retracts to drive the right slider 92 to slide on the right guide plate 91. The right slider 92 slides towards the right cylinder 93, and the position of the right slider 92 can be adjusted according to the size of the empty bottle to accommodate the large empty bottle. Conversely, when the conveyor belt 1 is conveying a small empty bottle, the right cylinder 93 extends to drive the right slider 92 to slide on the right guide plate towards the conveyor belt 1 to accommodate the small empty bottle.
[0047] Please see Figures 1-2 In this embodiment of the utility model, an empty bottle inspection machine including the above-mentioned height adjustment device is described. The working principle of the empty bottle inspection machine can be referred to ZL 202020202489.1, which describes the working principle of a glass bottle inspection device. It will not be described in this utility model.
[0048] When the conveyor belt 1 transports the contents to the detection range of the detection probe, the operator can use the detection probe to measure and identify the empty bottles. The wear of the recycled empty bottles can be detected by adjusting the detection parameters. Different detection parameters can detect empty bottles with different degrees of wear.
[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
