Description

Technical Field

[0001] The utility model relates to the field of plastic bottle production, and particularly relates to a plastic bottle mouth detection device. Background Art

[0002] The inner and outer diameters of the mouth of a glass bottle not only directly determine the airtightness of the bottle, but also have a crucial impact on the filling of the product inside the bottle and the encapsulation operation after filling. If the inner diameter of the mouth is too large, it may cause the liquid to splash out during filling, resulting in waste and pollution; if the inner diameter of the mouth is too small, it may hinder the smooth flow of the filling, leading to a reduction in the filling speed or insufficient filling volume. Similarly, the outer diameter of the mouth is crucial for the encapsulation process. The outer diameter must be precisely matched with the capping component of the capping machine to ensure that the bottle cap can be firmly sealed on the mouth of the bottle, neither too tight for consumers to open difficultly nor too loose to cause leakage. Therefore, it is necessary to detect the inner and outer diameters of the mouth. The existing detection method is to use a mouth detection camera and image processing technology to detect the size and shape of the inner and outer diameters of the mouth. The captured image is analyzed by professional image processing software. The software will measure the size and shape of the inner and outer diameters of the mouth according to preset parameters and algorithms. If it is detected that the deviation of the mouth size exceeds the preset tolerance range, the system will immediately issue an alarm to notify the operator to make adjustments.

[0003] However, the support structure of the existing mouth detection camera is mostly a fixed structure. Due to different batches of plastic bottles, their heights are also different. If the plastic bottle is relatively tall, it will collide with the mouth detection camera, causing scratches and cracks on the lens of the mouth detection camera, or the overall displacement of the mouth detection camera, affecting its accuracy and stability; if the plastic bottle is relatively short, it will cause the mouth detection camera to be unable to focus on the mouth of the bottle, and the image may be blurred and out of focus. The clear image will affect the accurate analysis of the inner and outer diameter sizes of the mouth by the image processing software, which may lead to incorrect detection results.

[0004] In response to this, in the prior art, a lifting device for adjusting the height of the mouth detection camera is introduced. The lifting device includes a mounting base and two support frames. The mounting base is used to mount the mouth detection camera. The two ends of the mounting base are respectively slidably matched with the two support frames. A regulating device is provided on one side of any one of the support frames. The regulating device is used to drive one end of the mounting base to lift. Since the other end of the mounting base is not directly driven by the regulating device, during the lifting process, the lifting positions of the two ends of the mounting base will be asynchronous, causing the mounting base to tilt, resulting in the mouth detection camera deviating from the vertical direction and affecting the accuracy of detection. Content of the Utility Model

[0005] To solve the above technical problems, the present utility model provides a plastic bottle mouth detection device, aiming to solve the technical problem that since there is no direct transmission of the adjusting device at the other end of the mounting seat, during the lifting process, the lifting positions of both ends of the mounting seat will be asynchronous, causing the mounting seat to tilt, resulting in the bottle mouth detection camera deviating from the vertical direction and affecting the detection accuracy.

[0006] The technical solution of the present utility model to solve the above technical problems is as follows:

[0007] A plastic bottle mouth detection device includes a conveying frame, a conveyor belt is provided at the top of the conveying frame, and further includes a mounting seat, a detection camera body is provided at the bottom of the mounting seat, movable seats are provided at both ends of the mounting seat, two support frames are provided at the top of the conveyor belt, an activity cavity is opened inside the support frames, the movable seats at both ends of the mounting seat are slidably matched with the activity cavities of the two support frames, a first transmission gear is rotatably connected inside the two activity cavities, a transmission convex tooth is provided on one side of the two movable seats, the two first transmission gears are engaged with the transmission convex teeth of the two movable seats, a transmission seat is connected between the two support frames, two transmission rotating shafts are rotatably connected inside the transmission seat, one ends of the two transmission rotating shafts are respectively coaxially driven with the two first transmission gears, second transmission gears are provided at the other ends of the two transmission rotating shafts, a third transmission gear and an auxiliary gear that are engaged with each other are rotatably connected inside the transmission seat, the third transmission gear and the auxiliary gear are located between the two second transmission gears, and the third transmission gear and the auxiliary gear are respectively engaged with the adjacent second transmission gears.

[0008] When it is necessary to adjust the height of the mounting seat, rotate the third transmission gear. Since the third transmission gear is engaged with the auxiliary gear, and the third transmission gear and the auxiliary gear are engaged with the adjacent second transmission gears, the third transmission gear and the auxiliary gear respectively drive the two second transmission gears to rotate. If the third transmission gear directly drives the two second transmission gears, the rotation directions of the two second transmission gears will be inconsistent. The auxiliary gear is responsible for correcting the rotation direction of any one of the second transmission gears, so that the rotation directions of the two second transmission gears are the same. The rotation of the second transmission gear is transmitted to the first transmission gear through the transmission rotating shaft. Since the transmission convex teeth on one side of the two movable seats are engaged with the two first transmission gears, the movable seats at both ends of the mounting seat are synchronously slid in the activity cavities of the support frames, avoiding the possible tilt or asynchrony problems of the mounting seat during the lifting process, and ensuring the stability of the camera body and the detection accuracy.

[0009] Further, in this application, two auxiliary rings are provided inside the transmission seat, a stable bearing is provided inside the auxiliary rings, and the two transmission rotating shafts are respectively rotatably matched with the inner rings of the stable bearings of the two auxiliary rings.

[0010] The stable bearing provides a stable rotation fulcrum for the transmission rotating shaft, ensuring the accuracy and stability of the transmission rotating shaft during rotation. Moreover, the stable bearing can absorb the vibration during the transmission of the transmission rotating shaft, reduce the influence on the transmission rotating shaft, and improve the stability and durability of the transmission rotating shaft.

[0011] Further, in the present application, one side of the transmission seat is rotatably connected with an adjusting turntable, and the adjusting turntable is coaxially driven with the third transmission gear.

[0012] By the coaxial drive of the adjusting turntable and the third transmission gear, the rotation of the adjusting turntable can be directly transmitted to the third transmission gear, thereby improving the transmission efficiency and reducing the energy loss.

[0013] Further, in the present application, a deceleration ring is provided on one side of the adjusting turntable. The deceleration ring has elasticity, and the deceleration ring abuts against one side of the transmission seat.

[0014] Further, in the present application, a plurality of first fixing holes are formed inside the adjusting turntable, and a second fixing hole is formed on one side of the transmission seat. A fixing bolt is inserted into any one of the first fixing holes, and one end of the fixing bolt is in threaded fit with the second fixing hole.

[0015] Further, in the present application, an auxiliary sliding groove is formed on one side of the movable cavity, and an auxiliary sliding block is provided on one side of the movable seat. The auxiliary sliding block is slidably engaged with the auxiliary sliding groove.

[0016] Further, in the present application, two limiting blocks are provided on one side of the movable seat, and the transmission convex teeth are located between the two limiting blocks.

[0017] Further, in the present application, an adjusting sliding groove is formed at the bottom of the mounting seat, an adjusting sliding block is slidably connected inside the adjusting sliding groove, an adjusting seat is provided at the bottom of the adjusting sliding block, and the detection camera body is provided at the bottom of the adjusting seat.

[0018] Further, in the present application, an auxiliary handle is provided on one side of the adjusting seat, and the auxiliary handle is in an n shape.

[0019] Further, in the present application, a plurality of first adjusting holes are formed inside the mounting seat, a second adjusting hole is formed at the top of the adjusting seat, and an adjusting pin is inserted into any one of the first adjusting holes. The adjusting pin is inserted into the second adjusting hole.

[0020] The present utility model has the following beneficial effects:

[0021] When the height of the mounting seat needs to be adjusted, rotate the third transmission gear. Since the third transmission gear meshes with the auxiliary gear, and the third transmission gear and the auxiliary gear mesh with the adjacent second transmission gears, the third transmission gear and the auxiliary gear drive the two second transmission gears to rotate respectively. If the third transmission gear directly drives the second transmission gear, the rotation directions of the two second transmission gears will be inconsistent. The auxiliary gear is responsible for correcting the rotation direction of any one of the second transmission gears so that the rotation directions of the two second transmission gears are the same. The rotation of the second transmission gear is transmitted to the first transmission gear through the transmission rotating shaft. Since the transmission convex teeth on one side of the two movable seats mesh with the two first transmission gears, the movable seats at both ends of the mounting seat are synchronously slid in the movable cavity of the support frame, avoiding the possible inclination or asynchronism problems during the lifting process of the mounting seat, and ensuring the stability and detection accuracy of the camera body.

[0032] Refer to Figures 1 - 5, in some specific embodiments, a plastic bottle mouth detection device includes a conveying rack 1. A conveyor belt 2 is provided on the top of the conveying rack 1. It further includes a mounting seat 6. A detection camera body 8 is provided at the bottom of the mounting seat 6. Moving seats 5 are provided at both ends of the mounting seat 6. Two support frames 3 are provided on the top of the conveyor belt 2. A moving cavity 4 is formed inside the support frame 3. The moving seats 5 at both ends of the mounting seat 6 are slidably matched with the moving cavities 4 of the two support frames 3. A first transmission gear 9 is rotatably connected in the two moving cavities 4. A transmission convex tooth 30 is provided on one side of the two moving seats 5. The two first transmission gears 9 are engaged with the transmission convex teeth 30 of the two moving seats 5. A transmission seat 10 is connected between the two support frames 3. Two transmission rotating shafts 12 are rotatably connected inside the transmission seat 10. One ends of the two transmission rotating shafts 12 are coaxially driven with the two first transmission gears 9 respectively. Second transmission gears 13 are provided at the other ends of the two transmission rotating shafts 12. A third transmission gear 16 and an auxiliary gear 15 that are engaged with each other are rotatably connected inside the transmission seat 10. The third transmission gear 16 and the auxiliary gear 15 are located between the two second transmission gears 13. The third transmission gear 16 and the auxiliary gear 15 are respectively engaged with the adjacent second transmission gears 13.

[0033] Through the above technical solution, when it is necessary to adjust the height of the mounting seat 6, rotate the third transmission gear 16. Since the third transmission gear 16 is engaged with the auxiliary gear 15, and the third transmission gear 16 and the auxiliary gear 15 are engaged with the adjacent second transmission gears 13, the third transmission gear 16 and the auxiliary gear 15 drive the two second transmission gears 13 to rotate respectively. If the third transmission gear 16 is directly transmitted with the two second transmission gears 13, the rotation directions of the two second transmission gears 13 will be inconsistent. The auxiliary gear 15 is responsible for correcting the rotation direction of any one of the second transmission gears 13, so that the rotation directions of the two second transmission gears 13 are consistent. The rotation of the second transmission gear 13 is transmitted to the first transmission gear 9 through the transmission rotating shaft 12. Since the transmission convex teeth 30 on one side of the two moving seats 5 are engaged with the two first transmission gears 9, the moving seats 5 at both ends of the mounting seat 6 are driven to slide synchronously in the moving cavities 4 of the support frames 3, avoiding the possible inclination or out-of-step problems during the lifting and lowering process of the mounting seat 6, and ensuring the stability and detection accuracy of the camera body.

[0034] In addition, the rotation of the third transmission gear 16 can be manually rotated or driven by a motor or mechanically linked by a motor.

[0035] Refer to Figure 4 , in some specific embodiments, two auxiliary rings 17 are provided inside the transmission seat 10. A stable bearing 18 is provided inside the auxiliary ring 17. The two transmission rotating shafts 12 are respectively rotatably matched with the inner rings of the stable bearings 18 of the two auxiliary rings 17.

[0036] Through the above technical solution, the stable bearing 18 provides a stable rotation fulcrum for the transmission rotating shaft 12, ensuring the accuracy and stability of the transmission rotating shaft 12 during rotation. Moreover, the stable bearing 18 can absorb the vibration during the transmission of the transmission rotating shaft 12, reduce the impact on the transmission rotating shaft 12, and improve the stability and durability of the transmission rotating shaft 12.

[0037] Referring to Figures 3 - 5 , in some specific embodiments, one side of the transmission seat 10 is rotatably connected with an adjusting turntable 19, and the adjusting turntable 19 is coaxially driven with the third transmission gear 16.

[0038] Through the above technical solution, by the coaxial drive of the adjusting turntable 19 and the third transmission gear 16, the rotation of the adjusting turntable 19 can be directly transmitted to the third transmission gear 16, thereby improving the transmission efficiency and reducing the energy loss.

[0039] Referring to Figure 5 , in some specific embodiments, a deceleration ring 22 is provided on one side of the adjusting turntable 19. The deceleration ring 22 has elasticity, and the deceleration ring 22 abuts against one side of the transmission seat 10.

[0040] Through the above technical solution, the design of the deceleration ring 22 enables the rotation speed of the adjusting turntable 19 to be restricted when the adjusting turntable 19 rotates reversely, thereby slowing down the rotation speed of the adjusting turntable 19. Due to the reduction of the reverse rotation speed of the adjusting turntable 19, the mechanical impact will also be correspondingly reduced, preventing the transmission components from being damaged due to the impact force.

[0041] Referring to Figure 5 , in some specific embodiments, a plurality of first fixing holes 20 are formed inside the adjusting turntable 19, and a second fixing hole 21 is formed on one side of the transmission seat 10. A fixing bolt 23 is inserted into any one of the first fixing holes 20, and one end of the fixing bolt 23 is in threaded fit with the second fixing hole 21.

[0042] Through the above technical solution, after the detection camera body 8 adjusts its height, the fixing bolt 23 passes through any one of the first fixing holes 20, so that one end of the fixing bolt 23 is in threaded fit with the second fixing hole 21, thereby fixing the rotation position of the adjusting turntable 19 and ensuring the stable position of the detection camera body 8 during the detection process, avoiding detection errors caused by improper operation.

[0043] Referring to Figures 2 - 3 , in some specific embodiments, an auxiliary sliding groove 31 is formed on one side of the movable cavity 4, and an auxiliary sliding block 32 is provided on one side of the movable seat 5. The auxiliary sliding block 32 is slidably matched with the auxiliary sliding groove 31.

[0044] Through the above technical solution, the sliding fit between the auxiliary slider 32 and the auxiliary sliding groove 31 helps to ensure the stability and accuracy of the movable seat 5 during movement, thereby reducing the position deviation of the movable seat 5 caused by friction or vibration during movement.

[0045] Referring to Figures 3 - 5 , in some specific embodiments, two limit blocks 29 are provided on one side of the movable seat 5, and the transmission convex teeth 30 are located between the two limit blocks 29.

[0046] Through the above technical solution, since the transmission convex teeth 30 are located between the limit blocks 29, it is ensured that when the movable seat 5 moves, the limit blocks 29 limit the position of the first transmission gear 9, so that the transmission convex teeth 30 can stably mesh with the first transmission gear 9.

[0047] Referring to Figures 2 - 3 , in some specific embodiments, an adjustment sliding groove 33 is formed at the bottom of the mounting seat 6, an adjustment slider 25 is slidably connected inside the adjustment sliding groove 33, an adjustment seat 7 is provided at the bottom of the adjustment slider 25, and the detection camera body 8 is provided at the bottom of the adjustment seat 7.

[0048] Through the above technical solution, by sliding the adjustment slider 25 in the adjustment sliding groove 33, the operator can adjust the position of the detection camera according to actual needs to obtain the best detection effect.

[0049] Referring to Figure 2 , in some specific embodiments, an auxiliary handle 24 is provided on one side of the adjustment seat 7, and the auxiliary handle 24 is in an n shape.

[0050] Referring to Figures 1 - 3 , in some specific embodiments, a plurality of first adjustment holes 26 are formed inside the mounting seat 6, a second adjustment hole 28 is formed at the top of the adjustment seat 7, an adjustment pin 27 is inserted into any one of the first adjustment holes 26, and the adjustment pin 27 is inserted into the second adjustment hole 28.

[0051] Through the above technical solution, by inserting the adjustment pin 27 into the first adjustment hole 26 and the second adjustment hole 28, the movement of the adjustment seat 7 on the mounting seat 6 can be prevented, ensuring the stable position of the detection camera body 8.

[0052] Note that, in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or apparatus comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or apparatus.
