Description

Technical Field

[0001] This utility model belongs to the field of sheet material production technology, and in particular relates to a sheet material conveying device. Background Technology

[0002] Currently, in automated production processes for sheet products, some defective products are inevitably produced due to factors such as production technology or raw materials. To ensure the overall quality of the final product, a dedicated defective product rejection system is usually required on the production line. A common technical solution involves creating rejection ports at key locations on the product conveyor. When the conveyor belt accurately delivers the identified defective product to the corresponding position at the rejection port, the rejection mechanism immediately initiates the rejection action. Specifically, the rejection mechanism applies a downward force, causing the defective product to fall through the rejection port into a designated collection bin. A guide structure is typically installed between the rejection port and the collection bin to guide the defective product. However, during the rejection process, the defective product may become stuck at the top of the guide structure. This sticking of the defective product can affect subsequent product rejection and transport.

[0003] To solve the above-mentioned technical problems, this utility model designs a sheet material conveying device. Utility Model Content

[0004] This invention provides a sheet material conveying device, which aims to solve the problem that defective products may get stuck at the top of the guide structure of the rejection port.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sheet material conveying device, comprising a conveying section and a rejection mechanism, wherein the conveying section includes a first end and a second end, the first end and the second end being arranged sequentially along the sheet material conveying direction, the second end being provided with a rejection position, the rejection mechanism being arranged corresponding to the rejection position, the rejection position being provided with a storage bin, a guide plate being provided between the rejection position and the storage bin, the top of the guide plate being provided with a guide shaft, the guide shaft being rotatable relative to the guide plate and extending perpendicular to the sheet material conveying direction.

[0006] Based on the above technical solution, the sheet material conveying device also includes a driving mechanism, which is located on one side of the conveying section and connected to the guide shaft for driving the guide shaft to rotate relative to the guide plate.

[0007] Furthermore, the driving mechanism includes a drive motor, a driving wheel, a first driven wheel, and a second driven wheel. The drive motor and the driving wheel are jointly fitted with a first belt. The first driven wheel is connected to the driving wheel and can rotate with the rotation of the driving wheel. The first driven wheel and the second driven wheel are jointly fitted with a second belt. The second driven wheel is located at the end of the guide shaft to drive the guide shaft to rotate.

[0008] Based on the above technical solution, the conveying section is fitted with a conveyor belt, and a pressing component is provided above the conveyor belt near the rejection position. The pressing component and the rejection mechanism are arranged sequentially along the conveying direction of the sheet material.

[0009] Furthermore, the pressing assembly includes a rotating shaft and a rotating pressure roller. The rotating shaft extends in a direction perpendicular to the conveying direction of the sheet material. The rotating pressure roller is sleeved on the rotating shaft and rotates with the rotation of the rotating shaft. The linear velocity of the rotating pressure roller is the same as the running speed of the conveyor belt.

[0010] Preferably, there are multiple rotating pressure rollers, which can move relative to the rotation axis to adjust the distance between adjacent rotating pressure rollers.

[0011] Based on the above technical solution, the driving mechanism further includes a third driven wheel, which meshes with the driving wheel. The third driven wheel is located at the end of the rotating shaft and is used to drive the rotating shaft to rotate.

[0012] Furthermore, the rejection mechanism includes a crossbeam, a drive member, and a rejection plate. The crossbeam extends perpendicular to the conveying direction of the sheet material. The drive member is disposed on the crossbeam and can move up and down relative to the crossbeam. The rejection plate is connected to the drive member.

[0013] Compared with related technologies, the beneficial effects of this utility model are as follows:

[0014] In this invention, sheet-like materials are conveyed from the first end to the second end along a conveyor section. When the sheet-like materials are defective, they reach the rejection position at the second end. The rejection mechanism acts downwards, rejecting the sheet-like materials along the guide plate into the storage bin below. When sheet-like materials get stuck at the top of the guide plate at the rejection position, the guide shaft at the top of the guide plate rotates, which can drive the stuck bag to move away from the rejection position, thus avoiding affecting the rejection of subsequent defective materials and the normal transmission of subsequent materials, thereby improving work efficiency.

[0024] Combination Figure 1 As shown, this embodiment of the present disclosure provides a sheet material conveying device, including a conveying section 1 and a rejection mechanism 2. The conveying section 1 includes a first end 11 and a second end 12, which are arranged sequentially along the sheet material conveying direction. The second end 12 is provided with a rejection position 121. The rejection mechanism 2 is correspondingly arranged with the rejection position 121. The rejection position 121 is correspondingly provided with a storage bin. A guide plate 122 is provided between the rejection position 121 and the storage bin. A guide shaft 123 is provided at the top of the guide plate 122. The guide shaft 123 is rotatable relative to the guide plate 122 and extends perpendicular to the sheet material conveying direction.

[0025] Using the sheet material conveying device provided in this embodiment, sheet material is conveyed from the first end 11 to the second end 12 along the conveying section 1. When the sheet material is defective, it reaches the rejection position 121 at the second end 12. The rejection mechanism 2 acts downward to reject the sheet material along the guide plate 122 into the storage bin below. When the sheet material is stuck at the rejection position 121 at the top of the guide plate 122, the guide shaft 123 at the top of the guide plate 122 rotates, which can drive the stuck bag to move away from the rejection position 121, thus avoiding affecting the rejection of subsequent defective materials and the normal conveying of subsequent materials, and improving work efficiency.

[0026] Based on the above technical solutions, such as Figure 1 As shown, the sheet material conveying device also includes a drive mechanism 3, which is located on one side of the conveying section 1. The drive mechanism 3 is connected to the guide shaft 123 and is used to drive the guide shaft 123 to rotate relative to the guide plate 122. The drive mechanism 3 provides power for the rotation of the guide shaft 123.

[0027] Furthermore, such as Figure 2As shown, the drive mechanism 3 includes a drive motor 31, a drive wheel 32, a first driven wheel 33, and a second driven wheel 34. The drive motor 31 and the drive wheel 32 are jointly fitted with a first belt 35. The first driven wheel 33 is connected to the drive wheel 32 and can rotate with the rotation of the drive wheel 32. The first driven wheel 33 and the second driven wheel 34 are jointly fitted with a second belt 36. The second driven wheel 34 is located at the end of the guide shaft 123 to drive the guide shaft 123 to rotate.

[0028] Specifically, the drive motor 31 drives the drive wheel 32 to rotate via the first belt 35, and the first driven wheel 33 rotates along with the drive wheel 32. The first driven wheel 33 drives the second driven wheel 34 to rotate via the second belt 36, thereby driving the guide shaft 123 to rotate relative to the guide plate 122. The rotation of the guide shaft 123 causes the stuck sheet material to move away from the rejection position 121.

[0029] Based on the above technical solutions, such as Figure 1 As shown, the conveying section 1 is equipped with a conveyor belt 13, and a pressing component 14 is provided above the conveyor belt 13 near the rejection position 121. The pressing component 14 and the rejection mechanism 2 are arranged sequentially along the conveying direction of the sheet material.

[0030] Sheet-shaped materials are conveyed by conveyor belt 13 on conveyor section 1. When the sheet-shaped materials are defective and need to be rejected, rejection mechanism 2 applies a downward force to the front end of the defective materials when the defective materials reach rejection position 121. The defective materials are rejected below rejection position 121 as the conveyor belt 13 moves. The clamping component 14 can press the rear end of the sheet-shaped materials firmly onto the conveyor belt 13, preventing the rear end of the defective materials from lifting or the entire defective materials from shifting position, making the rejection of defective materials smoother and improving rejection efficiency. In addition, when the sheet-shaped materials pass through rejection position 121 during the conveying process, the clamping component 14 can prevent the sheet-shaped materials from getting stuck, ensuring the smooth conveying of the sheet-shaped materials.

[0031] Optionally, the rotation direction of the guide shaft 123 can be the same as or opposite to the rotation direction of the conveyor belt 13. Preferably, the rotation direction of the guide shaft 123 is the same as the rotation direction of the conveyor belt 13, which can more smoothly drive the movement of sheet materials that are stuck.

[0032] Furthermore, such as Figure 2 As shown, the pressing assembly 14 includes a rotating shaft 141 and a rotating pressure roller 142. The rotating shaft 141 extends in a direction perpendicular to the conveying direction of the sheet material. The rotating pressure roller 142 is sleeved on the rotating shaft 141 and rotates with the rotation of the rotating shaft 141. The linear speed of the rotating pressure roller 142 is the same as the running speed of the conveyor belt 13.

[0033] Specifically, the rotating pressure roller 142 works in conjunction with the conveyor belt 13 to press the sheet material between them. During the rotation of the rotating shaft 141, the rotating pressure roller 142 rotates simultaneously. The linear speed of the rotating pressure roller 142 is the same as the running speed of the conveyor belt 13, working together to smoothly convey the sheet material forward or smoothly complete the rejection operation. The sheet material can be packaging bags or paper, etc.

[0034] Preferably, such as Figure 1 As shown, there are multiple rotating pressure rollers 142, and these multiple rotating pressure rollers 142 can move relative to the rotating shaft 141 to adjust the distance between adjacent rotating pressure rollers 142.

[0035] Specifically, multiple baffle units are provided above the conveying section 1, and these baffle units are evenly distributed to form multiple conveying channels. Multiple rotating pressure rollers 142 are correspondingly arranged in each conveying channel, with two rotating pressure rollers 142 evenly distributed within each channel. When sheet material passes over the rotating pressure rollers 142, the two rollers 142 press evenly against the sheet material, resulting in a more uniform force and smoother conveying. Furthermore, the rotating pressure rollers 142 can move relative to the rotating shaft 141, allowing their position to be adjusted according to the size of the sheet material or the width of the conveying channel, thus accommodating the conveying of sheet materials of different specifications.

[0036] Based on the above technical solutions, such as Figure 2 As shown, the drive mechanism 3 also includes a third driven wheel 37, which meshes with the driving wheel 32. The third driven wheel 37 is located at the end of the rotating shaft 141 and is used to drive the rotating shaft 141 to rotate.

[0037] Specifically, the drive motor 31 drives the drive wheel 32 to rotate via the first belt 35, and the third driven wheel 37 rotates along with the drive wheel 32. The rotation of the third driven wheel 37 drives the rotating shaft 141 of the pressing assembly 14 to rotate, thereby driving the rotating pressure wheel 142 to rotate, and cooperating with the transmission belt to press the sheet material during the transmission process.

[0038] Furthermore, such as Figure 3 As shown, the rejection mechanism 2 includes a crossbeam 21, a driving member 22, and a rejection plate 23. The crossbeam 21 extends along a direction perpendicular to the conveying direction of the sheet material. The driving member 22 is disposed on the crossbeam 21 and can move up and down relative to the crossbeam 21. The rejection plate 23 is connected to the driving member 22.

[0039] When the drive unit 22 moves downward relative to the crossbeam 21, the rejection plate 23 contacts the sheet material to be rejected and rejects the sheet material below the rejection position 121. The drive unit 22 can be a cylinder, hydraulic cylinder, or electric cylinder, etc. The drive unit 22 is located on the crossbeam 21 and can slide relative to the crossbeam 21, thereby moving the position of the rejection plate 23 and adjusting the spacing between multiple rejection plates 23. The rejection plate 23 can be a straight plate or an arc-shaped plate.

[0040] Specifically, the rejection plate 23 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 23 is adjustable and can be adjusted according to the size of the thin product being conveyed, so as to facilitate subsequent rejection operations.

[0041] 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.
