Description

Technical Field

[0001] The utility model relates to the field of plastic bottle production, in particular to a conveying and limiting structure for bottle caps. Background Art

[0002] In modern industrial production, the processing and manufacturing of bottle caps is a highly automated or semi-automated process. The production and processing of bottle caps usually include multiple links such as stamping, forming, cleaning, drying, printing, and inspection. In this process, the transformation of bottle caps from raw materials to finished products involves multiple processing procedures. In order to ensure that the bottle caps can smoothly enter the next process, the adjustment of the conveying position of the bottle caps is particularly important. Usually, the conveying position of the bottle caps is corrected by two limiting plates. When the batch of bottle caps on the conveying line changes, the size of the bottle caps will change, and the positions of the two limiting plates need to be adjusted by an adjusting device to adapt to the size of the new batch of bottle caps. However, the existing limiting plates all have independent adjusting devices, which means that each limiting plate can be adjusted independently without being affected by the position of the other limiting plate. If the positions adjusted by the two limiting plates are inconsistent, the conveying position of the bottle caps will not be centered, resulting in defects in the processing of the bottle caps, such as: the printed pattern of the bottle cap is offset, affecting the appearance and quality; the inspection equipment cannot accurately identify the bottle cap, resulting in mis-inspection or missed inspection, causing inconvenience in production. Summary of the Utility Model

[0003] To solve the above technical problems, the utility model provides a conveying and limiting structure for bottle caps, aiming to solve the technical problems that the existing limiting plates all have independent adjusting devices, which means that each limiting plate can be adjusted independently without being affected by the position of the other limiting plate. If the positions adjusted by the two limiting plates are inconsistent, the conveying position of the bottle caps will not be centered, resulting in defects in the processing of the bottle caps.

[0004] The technical solution of the utility model to solve the above technical problems is as follows:

[0005] A conveying and limiting structure for bottle caps includes a conveying frame. A conveyor belt and two limiting plates are arranged on the top of the conveying frame. The two limiting plates are located on both sides of the top of the conveyor belt. A limiting interval is formed between the two limiting plates. A supporting bottom frame is arranged on the top of the conveying frame. A supporting top plate is arranged on the top of the supporting bottom frame. The supporting top plate is located above the conveyor belt. A driving gear is rotatably connected to the bottom of the supporting top plate. Two driving bars are slidably connected to the bottom of the supporting top plate. A driving convex tooth is arranged on one side of the driving bar. The two driving bars are located on both sides of the driving gear, so that the driving convex teeth of the two driving bars are engaged with the driving gear. The two limiting plates are respectively connected to the bottoms of the two driving bars.

[0006] When it is necessary to adjust the positions of the two limit plates due to changes in the batches of the bottle caps, the transmission gear rotates. Since both transmission bars are engaged with the same transmission gear, the transmission gear drives the two transmission bars to move synchronously. Moreover, each limit plate is connected to the bottom of a transmission bar, so that when the two transmission bars move, they respectively drive the two limit plates to move synchronously, ensuring that the two limit plates always maintain the same position after adjustment, keeping the conveying direction of the bottle caps centered, and avoiding deviation in the conveying position of the bottle caps caused by inconsistent adjustment of the two limit plates.

[0007] Further, in the present application, two guiding chutes are opened at the bottom of the supporting top plate, guiding sliders are provided at the tops of the transmission bars, and the guiding sliders of the two transmission bars are respectively in sliding fit with the two guiding chutes.

[0008] The design of the guiding chutes and the guiding sliders ensures that the transmission bars always maintain a straight track during movement, prevents the transmission bars from shifting when transmitting power, improves the stability of the movement of the limit plates, and the sliding fit reduces friction, making the movement of the transmission bars smoother.

[0009] Further, in the present application, a plurality of first fixing jacks are opened in the guiding sliders, two second fixing jacks are opened inside the supporting top plate, fixing pins are inserted through the second fixing jacks, and the fixing pins of the two second fixing jacks are respectively inserted into any of the first fixing jacks of the two guiding sliders.

[0010] The plurality of first fixing jacks opened in the guiding sliders provide multiple position options. When the fixing pins pass through the second fixing jacks of the supporting top plate and are inserted into the first fixing jacks of the guiding sliders, the transmission bars are fixed on the supporting top plate, enabling the limit plates to be fixed at different positions as required.

[0011] Further, in the present application, an adjusting turntable is rotatably connected to the top of the supporting top plate, and the adjusting turntable is coaxially driven with the transmission gear.

[0012] Further, in the present application, an auxiliary bottom frame is provided at the top of the conveying frame, an auxiliary top plate is provided at the top of the auxiliary bottom frame, the auxiliary top plate is located above the conveyor belt, two auxiliary chutes are opened at the bottom of the auxiliary top plate, auxiliary sliders are provided at the tops of the limit plates, and the auxiliary sliders of the two limit plates are respectively in sliding fit with the two auxiliary chutes.

[0013] Further, in the present application, a limit top plate is provided on one side of the limit plate, and the limit top plate is located above the limit interval.

[0014] Further, in the present application, an adjustment sliding groove is formed on one side of the limit plate, an adjustment sliding block is provided on one side of the limit top plate, and the adjustment sliding block is slidably engaged with the adjustment sliding groove.

[0015] Further, in the present application, a plurality of first adjustment holes are formed inside the limit plate, a second adjustment hole is formed inside the adjustment sliding block, an adjustment bolt is inserted into any one of the first adjustment holes, and the adjustment bolt is in threaded engagement with the second adjustment hole.

[0016] Further, in the present application, the adjustment sliding groove is located above the limit interval.

[0017] Further, in the present application, the number of the limit top plates is two, the two limit top plates are respectively arranged on one side of the two limit plates, and there is an interval between the two limit top plates.

[0018] The utility model has the following beneficial effects:

[0019] When it is necessary to adjust the positions of the two limit plates due to the change in the batch of the bottle caps, the transmission gear rotates. Since the two transmission bars are both engaged with the same transmission gear, the transmission gear drives the two transmission bars to move synchronously. Moreover, each limit plate is connected to the bottom of one transmission bar, so that when the two transmission bars move, they respectively drive the two limit plates to move synchronously, ensuring that the two limit plates always maintain the same position after adjustment, keeping the conveying direction of the bottle caps centered, and avoiding the deviation of the conveying position of the bottle caps caused by inconsistent adjustment of the two limit plates.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present utility model, "a plurality" means two or more unless otherwise specifically defined.

[0030] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] Refer to Figures 1-6, in some specific embodiments, a conveying and limiting structure for a bottle cap includes a conveying rack 1. At the top of the conveying rack 1, there is a conveyor belt 2 and two limiting plates 5. The two limiting plates 5 are located on both sides of the top of the conveyor belt 2. The two limiting plates 5 are spaced apart to form a limiting interval 6. At the top of the conveying rack 1, there is a supporting bottom frame 3. At the top of the supporting bottom frame 3, there is a supporting top plate 4. The supporting top plate 4 is located above the conveyor belt 2. At the bottom of the supporting top plate 4, there is a driving gear 9 rotatably connected. At the bottom of the supporting top plate 4, there are two driving strips 10 slidably connected. On one side of the driving strip 10, there are driving convex teeth 11. The two driving strips 10 are located on both sides of the driving gear 9, so that the driving convex teeth 11 of the two driving strips 10 are engaged with the driving gear 9. The two limiting plates 5 are respectively connected to the bottoms of the two driving strips 10.

[0032] Through the above technical solution, when it is necessary to adjust the positions of the two limiting plates 5 due to the change of the batch of the bottle caps, the driving gear 9 rotates. Since the two driving strips 10 are both engaged with the same driving gear 9, the driving gear 9 drives the two driving strips 10 to move synchronously. And each limiting plate 5 is connected to the bottom of a driving strip 10, so that when the two driving strips 10 move, they respectively drive the two limiting plates 5 to move synchronously, ensuring that the two limiting plates 5 always maintain the same position after adjustment, keeping the conveying direction of the bottle caps centered, and avoiding the deviation of the conveying position of the bottle caps caused by the inconsistent adjustment of the two limiting plates 5.

[0033] In addition, the rotation of the driving gear 9 can be driven by a DC motor or a stepper motor or manually. When the driving gear 9 is driven by a DC motor, the DC motor provides a wide speed control range, which is suitable for a production line with variable bottle cap batches, so as to quickly adjust the position of the limiting plate 5. When the driving gear 9 is driven by a stepper motor, the stepper motor is suitable for occasions that require high-precision position control, such as bottle cap printing, so that the bottle caps can be conveyed more accurately centered. When the driving gear 9 is driven manually, the operation is simple and does not require a power or pneumatic system, so that the driving gear 9 is still available in case of power failure or other emergencies.

[0034] Refer to Figures 3-4 , in some specific embodiments, two guiding chutes 7 are opened at the bottom of the supporting top plate 4. At the top of the driving strip 10, there are guiding sliders 12. The guiding sliders 12 of the two driving strips 10 are respectively slidably engaged with the two guiding chutes 7.

[0035] Through the above technical solution, the design of the guiding chutes 7 and the guiding sliders 12 ensures that the driving strip 10 always maintains a straight track during the movement process, prevents the driving strip 10 from shifting when transmitting power, improves the stability of the movement of the limiting plate 5, and the sliding engagement reduces the friction, making the movement of the driving strip 10 smoother.

[0036] Reference Figures 3-4 In some specific embodiments, a plurality of first fixing jacks 13 are provided in the guiding slider 12, and two second fixing jacks 14 are provided inside the supporting top plate 4. A fixing pin 15 is inserted through the second fixing jack 14, and the fixing pins 15 of the two second fixing jacks 14 are respectively inserted into any one of the first fixing jacks 13 of the two guiding sliders 12.

[0037] Through the above technical solution, the plurality of first fixing jacks 13 provided in the guiding slider 12 provide multiple position options. When the fixing pin 15 passes through the second fixing jack 14 of the supporting top plate 4 and is inserted into the first fixing jack 13 of the guiding slider 12, the transmission bar 10 is fixed to the supporting top plate 4, so that the limiting plate 5 can be fixed at different positions as required.

[0038] Reference Figures 3-4 In some specific embodiments, an adjusting turntable 8 is rotatably connected to the top of the supporting top plate 4, and the adjusting turntable 8 is coaxially driven with the transmission gear 9.

[0039] Through the above technical solution, since the adjusting turntable 8 is coaxially driven with the transmission gear 9, it can ensure that the adjustment of the transmission gear 9 is synchronized with the movement of the transmission bar 10, reduce the complex transmission structure, and lower the maintenance difficulty.

[0040] Reference Figures 5-6 In some specific embodiments, an auxiliary bottom frame 22 is provided on the top of the conveying frame 1, an auxiliary top plate 23 is provided on the top of the auxiliary bottom frame 22, the auxiliary top plate 23 is located above the conveyor belt 2, two auxiliary sliding grooves 24 are provided at the bottom of the auxiliary top plate 23, auxiliary sliding blocks 25 are provided on the top of the limiting plate 5, and the auxiliary sliding blocks 25 of the two limiting plates 5 are respectively slidably matched with the two auxiliary sliding grooves 24.

[0041] Through the above technical solution, the sliding fit between the auxiliary sliding groove 24 and the auxiliary sliding block 25 improves the stability of the limiting plate 5 during the adjustment process, and reduces vibration and deviation.

[0042] Reference Figures 1-6 In some specific embodiments, a limiting top plate 16 is provided on one side of the limiting plate 5, and the limiting top plate 16 is located above the limiting interval 6.

[0043] Through the above technical solution, the limiting top plate 16 and the limiting plate 5 together form a semi-closed space, preventing the bottle cap from jumping out of the limiting interval 6 due to vibration or the change of the speed of the conveyor belt 2, and improving the stability of the bottle cap during the conveying process.

[0044] Reference Figures 5-6, in some specific embodiments, an adjustment chute 17 is formed on one side of the limit plate 5, and an adjustment slider 18 is provided on one side of the limit top plate 16. The adjustment slider 18 is slidably engaged with the adjustment chute 17.

[0045] Through the above technical solution, when the batch of the bottle caps changes, the height of the bottle caps also changes. To make the limit top plate 16 adapt to the height of the bottle caps, by pushing or pulling the adjustment slider 18, the distance between the limit top plate 16 and the limit interval 6 is changed, so as to adjust the height of the limit interval 6, facilitating the conveyance of the bottle caps of the new batch.

[0046] Refer to Figures 5-6 , in some specific embodiments, a plurality of first adjustment holes 19 are formed inside the limit plate 5, and a second adjustment hole 21 is formed inside the adjustment slider 18. An adjustment bolt 20 is inserted through any one of the first adjustment holes 19, and the adjustment bolt 20 is in threaded engagement with the second adjustment hole 21.

[0047] Through the above technical solution, the first adjustment holes 19 of the limit plate 5 provide a plurality of fixing points. When the adjustment bolt 20 is in threaded engagement with the second adjustment hole 21 of the adjustment slider 18, a firm connection is formed, thereby fixing the limit top plate 16 after the adjustment position, ensuring the stability of the limit interval 6 and the accuracy of the bottle cap conveyance.

[0048] Refer to Figures 5-6 , in some specific embodiments, the adjustment chute 17 is located above the limit interval 6.

[0049] Through the above technical solution, the adjustment chute 17 being located above the limit interval 6 means that the adjustment chute 17 does not directly contact the bottle caps, avoiding the direct contact between the adjustment slider 18 and the bottle caps, reducing possible interference and wear, and enabling the adjustment slider 18 to be adjusted without affecting the conveyance of the bottle caps.

[0050] Refer to Figures 5-6 , in some specific embodiments, the number of the limit top plates 16 is two. The two limit top plates 16 are respectively provided on one side of the two limit plates 5, and there is an interval between the two limit top plates 16.

[0051] Through the above technical solution, when the two limit plates 5 approach each other, due to the interval between the two limit top plates 16, the collision between the two limit top plates 16 is avoided, and at the same time, the limit top plates 16 are prevented from interfering with the movement of the limit plates 5.

[0052] Note that in this article, 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 term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device 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 device.
