Description

Technical Field

[0001] This utility model belongs to the field of thin product manufacturing technology, and in particular relates to a thin product conveying and rejection device. Background Technology

[0002] Currently, in the automated production process of thin products, due to factors such as production technology or raw materials, some products with quality defects are inevitably produced. To ensure the overall quality of the final product, a dedicated defective product rejection system is usually required on the production line. The commonly used technical solution is to open rejection ports at key locations on the product conveyor. When the conveyor belt accurately transports the detected defective product to the corresponding position of the rejection port, the rejection mechanism will immediately start to execute the rejection action. Specifically, the rejection mechanism applies a downward force, causing the defective product to fall into a designated collection container or waste area through the rejection port. However, in the actual rejection process, it has been found that when the defective product is subjected to a downward force, due to the characteristics of its thin structure, the rear end of the product will exhibit a significant upward warping phenomenon under the action of inertia. This unintended warping deformation not only causes the product's movement trajectory to deviate, but may also cause the product to collide or get stuck with the edge of the rejection port during the rejection process, seriously affecting the accuracy and reliability of the rejection operation, and may even interfere with the continuous conveying of subsequent normal products.

[0003] To solve the above-mentioned technical problems, this utility model designs a thin product conveying and rejection device. Utility Model Content

The first and second rejection positions are sequentially arranged along the thin product conveying direction. Rejection mechanisms are provided corresponding to the first and second rejection positions. The first and second conveying sections are respectively provided with a first conveyor belt and a second conveyor belt.

The first pressing component and the rejection mechanism corresponding to the first rejection position are sequentially arranged along the thin product conveying direction. A second pressing component is provided above the second conveyor belt near the second rejection position in the second conveying section. The second pressing component and the rejection mechanism corresponding to the second rejection position are sequentially arranged along the thin product conveying direction. The first pressing component and the second pressing component respectively press the thin products conveyed on the first and second conveyor belts.

[0006] Based on the above technical solution, both the first pressing assembly and the second pressing assembly include a rotating shaft and a rotating pressure roller. The rotating shaft extends along a direction perpendicular to the conveying direction of the thin product. The rotating pressure roller is sleeved on the rotating shaft and rotates with the rotation of the rotating shaft. The linear speed of the rotating pressure roller is the same as the running speed of the first conveyor belt and the second conveyor belt.

[0007] Furthermore, there are multiple rotating pressure rollers, which can move relative to the rotation axis to adjust the distance between adjacent rotating pressure rollers.

[0008] Based on the above technical solution, the thin product conveying and rejection device also includes a driving component, which is disposed on one side of the first conveying section and the second conveying section, and is used to drive the rotating shafts of the first pressing component and the second pressing component to rotate at the same speed.

[0009] Furthermore, the drive assembly includes a drive motor, a first drive wheel, a first driven wheel, a second drive wheel, and a second driven wheel. The first drive wheel and the first driven wheel mesh with each other. The first driven wheel is sleeved on the rotating shaft of the first pressing assembly.

[0011] Based on the above technical solution, the drive assembly further includes a third driven wheel group, which is located between the first driving wheel and the second driving wheel. The third driven wheel group includes two driven wheels, which are respectively connected to the first rear roller and the second front roller, and are used to drive the first rear roller and the second front roller to rotate.

[0012] Based on the above technical solution, the first rejection position and the second rejection position are respectively provided with a first storage bin and a second storage bin, and a guide plate is provided between the second rejection position and the second storage bin. The top of the guide plate is provided with a horizontal axis, which extends in a direction perpendicular to the conveying of thin products.

[0027] Combination Figure 1As shown in the figure, this disclosure provides a thin product conveying and rejection device, including a first conveying section 1, a second conveying section 2, and a rejection mechanism 3. A first rejection position 4 is provided between the first conveying section 1 and the second conveying section 2, and a second rejection position 5 is provided at the end of the second conveying section 2 away from the first conveying section 1. The first rejection position 4 and the second rejection position 5 are arranged sequentially along the thin product conveying direction, and the rejection mechanism 3 is correspondingly provided at the first rejection position 4 and the second rejection position 5. The first conveying section 1 and the second conveying section 2 are respectively provided with a first conveyor belt 11 and a second conveyor belt 21. A first pressing component 6 is provided above the first conveyor belt 11 near the first rejection position 4 in the first conveyor section 1. The first pressing component 6 and the rejection mechanism 3 corresponding to the first rejection position 4 are arranged sequentially along the thin product conveying direction. A second pressing component 7 is provided above the second conveyor belt 21 near the second rejection position 5 in the second conveyor section 2. The second pressing component 7 and the rejection mechanism 3 corresponding to the second rejection position 5 are arranged sequentially along the thin product conveying direction. The first pressing component 6 and the second pressing component 7 respectively press the thin products conveyed on the first conveyor belt 11 and the second conveyor belt 21.

[0028] Using the thin product conveying and rejection device provided in this embodiment, thin products are sequentially conveyed by the first conveyor belt 11 of the first conveyor section 1 and the second conveyor belt 21 of the second conveyor section 2. When a thin product needs to be rejected, the rejection mechanism 3 applies a downward force to the front end of the thin product when it reaches the first rejection position 4 or the second rejection position 5. The thin product is rejected below the first rejection position 4 or the second rejection position 5 as the first conveyor belt 11 or the second conveyor belt 21 moves. The first pressing component 6 or the second pressing component 7 can press the rear end of the thin product onto the first conveyor belt 11 or the second conveyor belt 21, preventing the rear end of the thin product from tilting up or the entire thin product from shifting position, making the rejection of the thin product smoother and improving rejection efficiency. In addition, when the thin product passes through the first rejection position 4 and the second rejection position 5 during the conveying process, the first pressing component 6 and the second pressing component 7 can prevent the thin product from getting stuck, ensuring the smooth conveying of the thin product.

[0029] Based on the above technical solutions, such as Figure 2 As shown, the first pressing assembly 6 and the second pressing assembly 7 both include a rotating shaft 61 and a rotating pressure roller 62. The rotating shaft 61 extends along a direction perpendicular to the conveying direction of the thin product. The rotating pressure roller 62 is sleeved on the rotating shaft 61 and rotates with the rotation of the rotating shaft 61. The linear velocity of the rotating pressure roller 62 is the same as the running speed of the first conveyor belt 11 and the second conveyor belt 21.

[0030] Specifically, the rotating pressure roller 62 works in conjunction with the first conveyor belt 11 and the second conveyor belt 21 to press the thin product between them. During the rotation of the rotating shaft 61, the rotating pressure roller 62 rotates simultaneously. The linear speed of the rotating pressure roller 62 is the same as the running speed of the first conveyor belt 11 and the second conveyor belt 21, working together to smoothly convey the thin product forward or smoothly complete the rejection operation. The thin product can be a packaging bag or paper, etc.

[0031] Preferably, the rotating pressure roller 62 is provided with an arc-shaped through hole. The number of the arc-shaped through holes is multiple, and the multiple arc-shaped through holes are evenly distributed circumferentially on the rotating pressure roller 62. The area of ​​each arc-shaped through hole increases from small to large as it extends from the center of the rotating pressure roller 62 to the surrounding areas.

[0032] Furthermore, such as Figure 1 As shown, there are multiple rotating pressure rollers 62, and these multiple rotating pressure rollers 62 can move relative to the rotating shaft 61 to adjust the distance between adjacent rotating pressure rollers 62.

[0033] Specifically, multiple baffle units are provided above the first conveying section 1, and these baffle units are evenly distributed to form multiple conveying channels. Multiple rotating pressure rollers 62 are correspondingly arranged in each conveying channel, with two rotating pressure rollers 62 evenly distributed within each channel. When a thin product passes over the rotating pressure rollers 62, the two rollers 62 press evenly against the product, resulting in a more uniform force and smoother conveying. Furthermore, the rotating pressure rollers 62 can move relative to the rotating shaft 61, allowing their position to be adjusted according to the size of the thin product or the width of the conveying channel, thus accommodating the conveying of thin products of different specifications.

[0034] Based on the above technical solutions, such as Figure 2 and Figure 3 As shown, the thin product conveying and rejection device also includes a drive assembly 8, which is disposed on one side of the first conveying section 1 and the second conveying section 2. The drive assembly 8 drives the rotating shafts 61 of the first pressing assembly 6 and the second pressing assembly 7 to rotate at the same speed. During the conveying of thin products, the operating speeds of the first conveyor belt 11 and the second conveyor belt 21 are generally the same or similar. The simultaneous rotation of the first pressing assembly 6 and the second pressing assembly 7 allows for better coordination with the first conveyor belt 11 and the second conveyor belt 21, enabling the thin product to pass smoothly from the first conveyor belt 11 into the second conveyor belt 21, avoiding slippage or jamming, and improving conveying stability.

[0035] Furthermore, such as Figure 2 and Figure 3As shown, the drive assembly 8 includes a drive motor 81, a first drive wheel 82, a first driven wheel 83, a second drive wheel 84, and a second driven wheel 85. The first drive wheel 82 and the first driven wheel 83 are meshed together. The first driven wheel 83 is sleeved on the rotating shaft 61 of the first pressing assembly 6. The second drive wheel 84 and the second driven wheel 85 are meshed together. The second driven wheel 85 is sleeved on the rotating shaft 61 of the second pressing assembly 7. The third conveyor belt 86 is sequentially sleeved on the drive motor 81, the first drive wheel 82, and the second drive wheel 84.

[0036] Specifically, during the operation of the drive assembly 8, the drive motor 81 drives the first drive wheel 82 and the second drive wheel 84 to rotate via the third conveyor belt 86. The first drive wheel 82 and the second drive wheel 84 drive the first driven wheel 83 and the second driven wheel 85 to rotate, respectively. The first driven wheel 83 and the second driven wheel 85 drive the rotating shaft 61 of the first pressing assembly 6 and the second pressing assembly 7 to rotate, thereby realizing the simultaneous rotation of the first pressing assembly 6 and the second pressing assembly 7.

[0037] Optionally, such as Figure 1 As shown, the first conveying section 1 is provided with a first front roller 12 and a first rear roller 13, and the first conveyor belt 11 is sleeved on the first front roller 12 and the first rear roller 13. The second conveying section 2 is provided with a second front roller 22 and a second rear roller 23, and the second conveyor belt 21 is sleeved on the second front roller 22 and the second rear roller 23.

[0038] Based on the above technical solutions, such as Figure 2 As shown, the drive assembly 8 also includes a third driven wheel group 87, which is located between the first drive wheel 82 and the second drive wheel 84. The third driven wheel group 87 includes two driven wheels 871, which are respectively connected to the first rear roller 13 and the second front roller 22, and are used to drive the first rear roller 13 and the second front roller 22 to rotate.

[0039] Specifically, during the operation of the drive assembly 8, the drive motor 81 drives the first driving wheel 82 and the second driving wheel 84 to rotate via the third conveyor belt 86, while simultaneously driving the two driven wheels 871 of the third driven wheel set 87 to rotate. The two driven wheels 871 respectively drive the first rear roller 13 and the second front roller 22 to rotate, thereby driving the operation of the first conveyor belt 11 and the second conveyor belt 21. In this way, while ensuring that the first driving wheel 82 and the second driving wheel 84, as well as the two driven wheels 871 of the third driven wheel set 87, are of the same type, the operation of the drive motor 81 ensures that the running speed of the first conveyor belt 11 and the second conveyor belt 21 matches the speed of the first pressing assembly 6 and the second pressing assembly 7.

[0040] Based on the above technical solutions, such as Figure 1 and Figure 3 As shown, the first rejection position 4 and the second rejection position 5 are respectively provided with a first storage bin and a second storage bin. A guide plate 9 is provided between the second rejection position 5 and the second storage bin. A horizontal axis 91 is provided on the top of the guide plate 9. The horizontal axis 91 extends in a direction perpendicular to the conveying of thin products.

[0041] Furthermore, such as Figure 3 As shown, the drive assembly 8 further includes a fourth driven wheel group 88, which includes a first rotating wheel 881, a second rotating wheel 882, and a fourth conveyor belt 883. The first rotating wheel 881 is connected to the second driving wheel 84 and can rotate with the rotation of the second driving wheel 84. The second rotating wheel 882 is located at the end of the horizontal shaft 91. The fourth conveyor belt 883 is sleeved on the first rotating wheel 881 and the second rotating wheel 882 and is used to drive the horizontal shaft 91 to rotate.

[0042] Specifically, while the drive motor 81 drives the second drive wheel 84 to rotate, it also drives the first rotating wheel 881 to rotate. The first rotating wheel 881 drives the second rotating wheel 882 to rotate through the fourth conveyor belt 883, thereby driving the horizontal shaft 91 to rotate. In this way, it can prevent thin products from getting stuck above the guide plate 9 when they are conveyed to the second rejection position 5. During the rotation of the horizontal shaft 91, the thin products can be driven to fall down so that subsequent products can be conveyed or rejected normally.

[0043] Based on the above technical solutions, such as Figure 4 As shown, the rejection mechanism 3 includes a crossbeam 31, a drive member 32, and a rejection plate 33. The crossbeam 31 extends along a direction perpendicular to the conveying direction of the thin product. The drive member 32 is disposed on the crossbeam 31 and can move up and down relative to the crossbeam 31. The rejection plate 33 is connected to the drive member 32.

[0044] When the drive unit 32 moves downward relative to the crossbeam 31, the rejection plate 33 contacts the thin product to be rejected and rejects the thin product below the first rejection position 4 or the second rejection position 5. The drive unit 32 can be a cylinder, hydraulic cylinder, or motor, etc. The drive unit 32 is located on the crossbeam 31 and can slide relative to the crossbeam 31, thereby moving the position of the rejection plate 33 and adjusting the spacing between multiple rejection plates 33. The rejection plate 33 can be a straight plate or an arc-shaped plate.

[0045] Specifically, the rejection plate 33 includes a first plate and a second plate, which are arranged side by side and can move relative to each other. The first plate and the second plate can move relative to each other to a first position where there is an overlap between the first plate and the second plate and a second position where there is a gap between the first plate and the second plate. In this way, the first plate and the second plate can move relative to each other, so that the width of the rejection plate 33 is adjustable and can be adjusted according to the size of the thin product being conveyed, so as to facilitate subsequent rejection operations.

[0046] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
