Description

Technical Field

[0001] This invention relates to the field of packaging equipment, and more particularly to a hexagonal belt rotating connection mechanism. Background Technology

[0002] refer to Figure 1 For some bagged products, there are strict requirements on the front and back orientation or the front and back orientation of the packaging bag when it is packed or packaged. Therefore, during the transportation of the bagged products, identification devices such as infrared (or visual recognition) are used to determine the front and back orientation or the front and back orientation of the packaging bag. If the front and back orientation or the front and back orientation of the packaging bag does not match the setting, the bagged products that do not meet the setting need to be screened out.

[0003] In existing technologies, a "nodding belt" is commonly used to screen out bagged products that do not meet the set parameters. The "nodding belt" has a swing arm at its front end. If the identification device detects that the front and back orientation or the front and back orientation of the bagged product packaging bag meets the set parameters, the swing arm remains horizontal (e.g., ...). Figure 1 As shown), this keeps the front section of the "bumper belt" horizontal, allowing the bagged product that meets the set parameters to pass through the "bumper belt" and continue to be conveyed forward to the next conveyor mechanism.

[0004] If the identification device detects that the front or back orientation or the orientation of the front or back of the bagged product packaging bag does not match the settings, the swing arm will swing downwards (e.g., Figure 2 As shown), this causes the front section of the "bumper belt" to swing downwards, creating a drop gap. This allows bagged products that do not conform to the settings, whether facing forward or backward, to slide down the slope and fall through the drop gap, thus screening out the non-conforming bagged products.

[0005] However, when a bagged product whose front and back orientation or front and back orientation does not conform to the settings is immediately followed by a bagged product whose front and back orientation or front and back orientation both conform to the settings (e.g.) Figure 2 In the scenario shown, the non-compliant bagged product will trigger the recognition device, causing the front section of the "bumper belt" to swing downwards. Thus, both the non-compliant and compliant bagged products will enter the downward-sloping front section of the "bumper belt" (as shown). Figure 2 As shown). When the non-compliant bagged product is conveyed forward and falls through the drop gap, the immediately following compliant bagged product will move forward to be close to the drop gap. At this time, to prevent the compliant bagged product from falling through the drop gap, the conveying of the "bumper belt" must be paused (so that the compliant bagged product is paused), and then the swing arm (front belt section) is controlled to swing to a horizontal state (as shown). Figure 1(As shown), then the "bumper belt" is restarted to resume the conveying of the bagged product that meets the settings.

[0006] Because it takes time for the swing arm (front belt section) to swing from an inclined downward state to a horizontal state, the entire "bumper belt" stops conveying during this period. In other words, there is a pause in the conveying process of the "bumper belt", which results in a low conveying efficiency of the "bumper belt". Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art, the present invention aims to provide a hexagonal belt rotating connection mechanism that can screen out products that do not meet the set requirements, and the belt does not need to be stopped during its entire operation, thereby improving the transmission efficiency.

[0008] The objective of this invention is achieved through the following technical solution:

[0009] A hexagonal belt rotating connection mechanism includes a fixed base, on which a rotation drive motor is mounted. A rear rotating plate is fixedly connected to the output shaft of the rotation drive motor. A front rotating plate is fixedly connected to the front side of the rear rotating plate via several connecting rods. Six rollers are rotatably arranged between the rear and front rotating plates. The six rollers are evenly distributed around the axis of the output shaft of the rotation drive motor. A conveyor belt is wound around the six rollers. A transmission shaft is provided between the rear and front rotating plates, and the front and rear ends of the transmission shaft are rotatably connected to the front and rear rotating plates, respectively. The fixed base is equipped with a drive motor. A first pulley and a second pulley are fixedly mounted on the transmission shaft. The drive shaft of the drive motor is connected to the first pulley via a first transmission belt. The second pulley is connected to one of the rollers via a second transmission belt. The fixed base is equipped with an opening / closing switching plate and a front conveying mechanism. The opening / closing switching plate is rotatably disposed between the conveyor belt and the front conveying mechanism. When the conveyor belt is in normal transmission mode, the opening / closing switching plate is tilted upwards from back to front. When the rear rotating plate rotates, the opening / closing switching plate rotates and switches to tilting upwards from front to back.

[0010] Specifically, the front rotating plate and the rear rotating plate are fixedly connected to each other by at least three connecting rods.

[0011] Specifically, a tensioning sliding plate is provided on the front side of the rear rotating plate. The tensioning sliding plate has a connecting elongated hole through which an adjusting screw passes. The adjusting screw is used to fix the tensioning sliding plate to the front side of the rear rotating plate. The tensioning sliding plate is provided with a tensioning wheel.

[0012] Specifically, the surfaces of all six rollers are provided with synchronous teeth, and the conveyor belt is a synchronous belt.

[0013] Specifically, the first pulley is a synchronous pulley, and the first transmission belt is a synchronous belt.

[0014] Specifically, the second pulley is a synchronous pulley, and the second transmission belt is a synchronous belt.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] When the identification device detects that the front or rear orientation or the front or back orientation of a product to be entered into the conveyor belt 32 does not conform to the setting, the identification device feeds back to the control system. The control system controls the rear rotating plate to rotate. When the product that does not conform to the setting enters the top section of the conveyor belt, the rotation drive motor drives the rear rotating plate to rotate 60° in the direction H, so that the product that does not conform to the setting rotates 60° in the direction H with the conveyor belt, thereby rotating to the front section of the conveyor belt. The front section is tilted downwards, and the product that does not conform to the setting will be conveyed forward by the conveyor belt, thereby falling and being screened out.

[0017] During the rotation of the rear rotating plate in the direction H by 60°, the opening and closing switching plate rotates until it tilts upward from front to back, with an angle c between the opening and closing switching plate and the horizontal plane, where 20°≤c≤70°. At this angle position, the opening and closing switching plate can block some non-conforming products that fly over to the front conveyor mechanism due to excessive speed, ensuring that non-conforming products do not enter the front conveyor mechanism. In addition, rotating the opening and closing switching plate to tilt upward from front to back can increase the distance between the front and rear edges of the opening and closing switching plate and the front section of the conveyor belt, thereby preventing the front and rear edges of the opening and closing switching plate from blocking or interfering with non-conforming products passing under it.

[0018] During the rotation of the rotating plate 60° in direction H driven by the aforementioned rotary drive motor, the conveyor belt continuously transports products in direction F. Therefore, the top section of the conveyor belt can uninterruptedly receive the products immediately following behind. Because the conveyor belt does not stop due to the rotation of the rear rotating plate during operation, it can achieve continuous transport, thereby improving transport efficiency.

[0034] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0035] See Figures 3 to 10The hexagonal belt rotating connection mechanism includes a fixed base, on which a rotating drive motor 1 is mounted. A rear rotating plate 34 is fixedly connected to the output shaft 11 of the rotating drive motor 1. A front rotating plate 36 is fixedly connected to the front side of the rear rotating plate 34 via several connecting rods 35. Six rollers 31 are rotatably mounted between the rear rotating plate 34 and the front rotating plate 36, and the six rollers 31 are evenly distributed around the axis of the output shaft 11 of the rotating drive motor 1. A conveyor belt 32 is wound around all six rollers 31. A transmission shaft 33 is provided between the rear rotating plate 34 and the front rotating plate 36, and the front and rear ends of the transmission shaft 33 are rotatably connected to the front rotating plate 36 and the rear rotating plate 34, respectively.

[0036] The fixed base is equipped with a drive motor 2, and a first pulley 331 and a second pulley 332 are fixedly fitted onto a transmission shaft 33. The drive shaft of the drive motor 2 is connected to the first pulley 331 via a first transmission belt 41, and the second pulley 332 is connected to one of the roller shafts 31 via a second transmission belt 42. The fixed base is equipped with an opening / closing switching plate 7 and a front conveying mechanism 6. The opening / closing switching plate 7 is rotatably disposed between the conveyor belt 32 and the front conveying mechanism 6 (see...). Figure 8 When the conveyor belt 32 is in normal drive mode, the opening / closing switching plate 7 tilts upwards from back to front (e.g.) Figure 8 , Figure 11 (As shown); when the rear rotating plate 34 rotates, the opening / closing switching plate 7 rotates to switch to tilting upwards from front to back (see reference). Figure 10 , Figure 12 ).

[0037] Specifically, the front rotating plate 36 and the rear rotating plate 34 are fixedly connected to each other by at least three connecting rods 35.

[0038] Specifically, a tensioning sliding plate 51 is provided on the front side of the rear rotating plate 34. The tensioning sliding plate 51 has a connecting elongated hole 511 through which an adjusting screw (not shown in the figure) passes. The adjusting screw is used to fix the tensioning sliding plate 51 to the front side of the rear rotating plate 34. The tensioning sliding plate 51 is provided with a tensioning wheel 52. By loosening the adjusting screw, the position of the tensioning sliding plate 51 can be adjusted along the connecting elongated hole 511, thereby adjusting the position of the tensioning wheel 52 and thus adjusting the tension of the tensioning wheel 52 on the second transmission belt 42.

[0039] Specifically, the surfaces of the six rollers 31 are all provided with synchronous teeth, and the conveyor belt 32 is a synchronous belt.

[0040] Specifically, the first pulley 331 is a synchronous pulley, and the first transmission belt 41 is a synchronous belt.

[0041] Specifically, the second pulley 332 is a synchronous pulley, and the second transmission belt 42 is a synchronous belt.

[0042] The working process of the hexagonal belt rotation connection mechanism of the present invention is as follows:

[0043] Comparison and combination Figure 11 , Figure 12 When the identification device (referring to the background art) identifies that the front and rear orientation or the front and back orientation of the product to be entered into the top section of the conveyor belt 32 conforms to the set parameters, the conveyor belt 32 is in a normal driving state (e.g., Figure 11 As shown): The rear rotating plate 34 remains stationary, the conveyor belt 32 conveys along direction F, the top side section of the conveyor belt 32 is inclined upward from back to front, the angle between the top side section of the conveyor belt 32 and the horizontal plane is a, 5°≤a≤40°, and the opening and closing switching plate 7 is inclined upward from back to front, the angle between the opening and closing switching plate 7 and the horizontal plane is b, 10°≤b≤50°.

[0044] See Figure 11 The identified product that meets the settings is conveyed by the rear conveyor mechanism to the top section of the conveyor belt 32, and then conveyed forward by the top section of the conveyor belt 32, gaining an upward tilting speed from back to front. This speed causes the product that meets the settings to continue flying forward due to inertia after leaving the top section of the conveyor belt 32, leaping to the top wall of the opening and closing switching plate 7, and sliding upward tilting along the top wall of the opening and closing switching plate 7, thereby entering the front conveyor mechanism 6 (e.g., Figure 11 Product 1) is then conveyed forward. During this process, the opening / closing switching plate 7 acts as a connecting element.

[0045] Comparison and combination Figure 11 , Figure 12 When the identification device (referring to the background art) detects that the front or rear orientation or the front or back orientation of a product to be entered into the conveyor belt 32 does not conform to the set parameters, the identification device feeds back to the control system. The control system controls the rear rotating plate 34 to rotate. When the product that does not conform to the set parameters enters the top section of the conveyor belt 32, the rotation drive motor 1 drives the rear rotating plate 34 to rotate 60° in the direction H, so that the product that does not conform to the set parameters rotates 60° in the direction H with the conveyor belt 32, thereby rotating to the front section of the conveyor belt 32 (for comparison). Figure 11 , Figure 12 The status of product 2, among which Figure 12 The state shown is the state during the rotation of the rear rotating plate 34 (not yet rotated 60°). The front section is tilted downwards. Products that do not meet the settings will continue to be conveyed forward by the conveyor belt 32, thus falling and being screened out.

[0046] During the rotation of the rear rotating plate 34 in the direction H by 60°, the opening / closing switching plate 7 rotates until it tilts upwards from front to back, and the angle between the opening / closing switching plate 7 and the horizontal plane is c, where 20°≤c≤70° (see...). Figure 12At this angle position: the opening and closing switching plate 7 can block some non-conforming products that fly over to the front conveyor 6 due to excessive speed, so as to ensure that non-conforming products do not enter the front conveyor 6. In addition, the opening and closing switching plate 7 can be rotated to tilt upward from front to back, which can increase the distance between the front and rear edges of the opening and closing switching plate 7 and the front section of the conveyor belt 32, thereby avoiding the front and rear edges of the opening and closing switching plate 7 from blocking or interfering with non-conforming products passing under it.

[0047] Comparison and combination Figure 11 , Figure 12 During the process of the rotating plate 34 rotating 60° in the direction H after being driven by the aforementioned rotary drive motor 1, the conveyor belt 32 continuously conveys along the direction F, so the top section of the conveyor belt 32 can continuously receive the products that follow (comparison). Figure 11 , Figure 12 (The state of product 3). Since the conveyor belt 32 does not stop during operation due to the rotation of the rear rotating plate 34, the conveyor belt 32 can achieve continuous conveying, thereby improving the conveying efficiency.
