Description

Technical Field

[0001] This application relates to the field of abrasive cloth processing equipment, and in particular to an abrasive cloth forming and dividing device. Background Technology

[0002] Abrasive cloth forming and slitting device is a piece of equipment used to process abrasive cloth, cutting large pieces of abrasive cloth material into the required size and shape. An abrasive cloth forming and slitting device typically consists of the following main components: a transport system, which conveys the abrasive cloth material to the slitting area using conveyor belts, rollers, or other suitable equipment; a slitting machine, the core component of the abrasive cloth forming and slitting device, capable of using different technologies and mechanics to perform the slitting operation, such as cutters, cutting wheels, or cutting blades; and a control system, used to control the conveying system and the slitting machine. This control system can be based on electricity, hydraulic pressure, or airflow, depending on the installation design and requirements.

[0003] The working principle of the abrasive cloth forming and slitting device is as follows: First, the abrasive cloth material is placed on the conveyor system, and then conveyed to the slitting machine through the control system. The slitting machine cuts the abrasive cloth material according to pre-set parameters and requirements, dividing it into the required shapes and sizes. Finally, the slid abrasive cloth material is collected and processed. This device is widely used in the abrasive cloth manufacturing and processing industry to produce abrasive cloth products of various shapes and sizes, such as abrasive cloth sheets and abrasive cloth belts. It can increase production capacity, ensure product quality consistency, and reduce labor and time costs.

[0004] For example, Chinese patent CN216781497U discloses an abrasive cloth slitting device that cuts abrasive cloth transported on an optical axis using a cutting tool assembly. In this patent, a specific cutting tool is used to cut the abrasive cloth transported by the transport system, dividing the abrasive cloth into the required shape and size, and finally collecting and processing the divided abrasive cloth material.

[0005] Regarding the aforementioned technologies, the inventors discovered that after the existing abrasive cloth forming and dividing devices divide the abrasive cloth into shapes, the abrasive cloth needs to be actively collected by workers. This increases labor costs and also restricts the abrasive cloth forming and dividing devices from improving the efficiency of abrasive cloth dividing. Summary of the Invention

[0006] In order to solve some or all of the above-mentioned technical problems, this application provides a sandpaper forming and dividing device.

[0007] The abrasive cloth forming and dividing device provided in this application adopts the following technical solution:

[0008] A sandpaper forming and dividing device includes: a frame erected on a horizontal ground; a first conveyor belt mounted on the frame for moving the sandpaper, a forming cylinder located below and communicating with the top of the first conveyor belt on the frame; a pressing mechanism mounted on the frame and located directly above the first conveyor belt; a pressing plate located directly above the forming cylinder and capable of moving vertically under the action of the pressing mechanism; a pressing cylinder located below the pressing plate and capable of moving vertically under the action of the pressing plate, and capable of dividing the sandpaper when moving downwards; a second conveyor belt located below the forming cylinder; and a receiving cylinder mounted on the second conveyor belt and positioned directly opposite the forming cylinder, capable of receiving the divided sandpaper from the pressing cylinder.

[0009] By adopting the above technical solution, when it is necessary to form and divide abrasive cloth, the abrasive cloth is first transported to the bottom of the pressing mechanism by the first conveyor belt. Then, the pressing mechanism is started to drive the pressing plate and pressing cylinder to move vertically. When the pressing cylinder moves downward, the side wall cuts the abrasive cloth. The cut abrasive cloth falls into the forming cylinder for collection. After being collected in the forming cylinder, it falls into the receiving cylinder for storage and transportation. The forming and stacking of abrasive cloth are completed automatically, reducing the labor intensity of workers.

[0010] Optionally, an opening and closing mechanism is provided below the forming cylinder to block the segmented sandpaper inside the forming cylinder and to release the segmented sandpaper when the number of sandpapers inside the forming cylinder reaches a set threshold.

[0011] By adopting the above technical solution and setting the opening and closing mechanism, the forming cylinder can initially collect the segmented abrasive cloth, which facilitates the stacking and collection of the segmented abrasive cloth.

[0012] Optionally, the opening and closing mechanism includes: two lower baffles, each hinged to the bottom wall of the forming cylinder, and capable of opening or closing relative to each other; a return spring disposed between the frame and the side wall of each lower baffle, wherein the return spring is fixedly connected to the middle of the side wall of the lower baffle; a rack fixedly connected to the lower surface of the pressing plate, and a transmission wheel meshing with the rack is disposed on the frame; a rotating shaft rotatably disposed on the frame, one end of which is fixedly connected to the side wall of the transmission wheel; a push rod slidably disposed on the frame, capable of pushing the lower baffle to close when moving towards the lower baffle; and a first connecting rod, one end of which is fixedly connected to the side wall of the rotating shaft, and the other end of which is connected to the end of the push rod away from the lower baffle.

[0013] By adopting the above technical solution, after the abrasive cloth falls into the forming cylinder, as the number of divided abrasive cloths accumulates, the weight of the accumulated divided abrasive cloths gradually increases until it exceeds a set threshold. Under the gravity of the divided abrasive cloths, the lower baffle tends to open and fully opens under the tension of the return spring. Subsequently, the divided abrasive cloths in the forming cylinder fall into the receiving cylinder for storage. In the next movement, the pressing plate drives the rack to move linearly, further driving the transmission wheel and the rotating shaft to rotate. Finally, the rotation of the rotating shaft drives the push rod to move down to the lower baffle, closing the lower baffle. After the lower baffle closes, the return spring tightens the lower baffle again, and the next round of material collection begins in the forming cylinder.

[0014] Optionally, the opening and closing mechanism further includes a roller rotatably connected to the end of the push rod near the lower baffle.

[0015] By adopting the above technical solution, the roller configuration facilitates the pushing action of the push rod on the lower baffle during its downward movement, reducing the probability of equipment damage.

[0016] Optionally, multiple molding cylinders, pressing cylinders, receiving cylinders, and opening / closing mechanisms are provided.

[0017] By adopting the above technical solution, the setting of multiple forming cylinders, pressing cylinders, receiving cylinders and opening and closing mechanisms can realize the simultaneous cutting and forming of multiple abrasive cloths, thus improving work efficiency.

[0018] Optionally, a linear actuator is provided inside the pressing cylinder, and a push plate is fixedly connected to the drive rod of the linear actuator.

[0019] By adopting the above technical solution, the linear driver and pusher plate can push the abrasive cloth into the forming cylinder after it is divided and formed, thus improving the neatness of the abrasive cloth stacking in the forming cylinder.

[0020] Optionally, a support plate is fixedly connected to the bottom wall of the linear actuator, and an air intake shell is fixedly connected to the lower surface of the support plate. The push plate is slidably disposed on the inner wall of the air intake shell, and multiple air vents are provided on the push plate.

[0021] By adopting the above technical solution, the suction shell and the setting of the vent hole can adsorb the abrasive cloth during the process of the pusher plate pushing down the segmented abrasive cloth, increasing the possibility of the abrasive cloth shaking on the lower surface of the pusher plate, and blowing the abrasive cloth away from the lower surface of the pusher plate during the process of the pusher plate moving up, reducing the probability of the abrasive cloth being stacked messily in the forming cylinder as the abrasive cloth moves up with the pusher plate.

[0022] Optionally, the linear actuator is a cylinder, a hydraulic cylinder, or an electromagnetic actuator.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When it is necessary to form and divide the abrasive cloth, the abrasive cloth is first transported to the bottom of the pressing mechanism by the first conveyor belt. Then, the pressing mechanism is started to drive the pressing plate and pressing cylinder to move vertically. When the pressing cylinder moves downward, the side wall cuts the abrasive cloth. The cut abrasive cloth falls into the forming cylinder for collection. After being collected in the forming cylinder, it falls into the receiving cylinder for storage and transportation. The forming and stacking of abrasive cloth are completed automatically, reducing the labor intensity of workers.

[0025] 2. After the abrasive cloth falls into the forming cylinder, as the number of divided abrasive cloths accumulates, the weight of the accumulated divided abrasive cloth gradually increases until it exceeds a set threshold. Under the gravity of the divided abrasive cloth, the lower baffle tends to open and fully opens under the tension of the return spring. Subsequently, the divided abrasive cloth in the forming cylinder falls into the receiving cylinder for storage. In the next movement, the pressing plate drives the rack to move linearly, further driving the transmission wheel and the rotating shaft to rotate. Finally, the rotation of the rotating shaft drives the push rod to move down to the lower baffle, closing the lower baffle. After the lower baffle closes, the return spring tightens the lower baffle again, and the next round of material collection begins in the forming cylinder.

[0026] 3. The design of the suction shell and vent holes can adsorb the abrasive cloth as the pusher plate pushes down the segmented abrasive cloth, increasing the possibility of the abrasive cloth shaking on the lower surface of the pusher plate. It can also blow the abrasive cloth away from the lower surface of the pusher plate as the pusher plate moves up, reducing the probability of the abrasive cloth being stacked haphazardly in the forming cylinder as the pusher plate moves up.

[0027] Furthermore, the abrasive cloth forming and dividing device of the present invention has the advantages of being safe and reliable to use, and is easy to implement and promote. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of the present invention. Figure 1-4 The technical solutions of the embodiments of the present invention will be clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.

[0035] This application discloses an abrasive cloth forming and dividing device. (Refer to...) Figure 1 and Figure 2 A sandpaper forming and dividing device includes a frame 1 erected on a horizontal ground. A first conveyor belt 11 and a forming cylinder 2 located below and communicating with the top of the first conveyor belt 11 are mounted on the frame 1. It should be noted that the first conveyor belt 11 in this application is not a conventional conveyor belt. In this application, the movement of the sandpaper on the first conveyor belt 11 is achieved by an external rotating source driving the sandpaper on the first conveyor belt 11. This rotating source can be a compression roller.

[0036] Reference Figure 1 and Figure 2 A pressing mechanism 3 is positioned directly above the first conveyor belt 11, and a pressing plate 21 is positioned directly above the forming cylinder 2. The pressing plate 21 can move vertically under the drive of the pressing mechanism 3. The pressing mechanism 3 is a device capable of linear movement, such as a cylinder, hydraulic cylinder, or electromagnetic push rod 45. A pressing cylinder 22 is fixedly connected below the pressing plate 21. The pressing cylinder 22 can move vertically under the drive of the pressing plate 21 and can divide the abrasive cloth when moving downwards. A second conveyor belt 12 is positioned below the forming cylinder 2, and a receiving cylinder 13 is placed on the second conveyor belt 12, facing the forming cylinder 2. The receiving cylinder 13 can receive the divided and shaped abrasive cloth from the pressing cylinder 22.

[0037] When it is necessary to form and divide the abrasive cloth, the abrasive cloth is first transported to the pressing mechanism 3 via the first conveyor belt 11. Then, the pressing mechanism 3 is started to drive the pressing plate 21 and the pressing cylinder 22 to move vertically. When the pressing cylinder 22 moves downward, the side wall cuts the abrasive cloth. The cut abrasive cloth falls into the forming cylinder 2 for collection. After being collected in the forming cylinder 2, it falls into the receiving cylinder 13 for storage and transportation. The forming and stacking of the abrasive cloth are completed automatically, reducing the labor intensity of workers.

[0038] A closing mechanism 4 is provided below the forming cylinder 2 to hold the segmented abrasive cloth inside the forming cylinder 2 and to release the segmented abrasive cloth when the amount of abrasive cloth inside the forming cylinder 2 reaches a set threshold. The set threshold is determined based on the weight of the segmented abrasive cloth. Specifically, the set number should be the number of segmented abrasive cloth segments that just allows the closing mechanism 4 to be opened. Those skilled in the art can set it according to actual conditions. The opening and closing mechanism 4 enables the forming cylinder 2 to initially collect the segmented abrasive cloth, facilitating the stacking and collection of the segmented abrasive cloth.

[0039] Reference Figure 2 and Figure 3 The opening and closing mechanism 4 includes two lower baffles 41 that are hinged to the bottom wall of the forming cylinder 2. The two lower baffles 41 can open or close relative to each other. A return spring 42 is provided between each lower baffle 41 and the frame 1. The return spring 42 is fixedly connected to the middle of the side wall of the lower baffle 41. The arrangement of the return spring 42 here is such that when the length direction of the return spring 42 is parallel to the plate surface of the lower baffle 41, the return spring 42 can pull the lower baffle 41 to open when it continues to rotate downward, and can pull the lower baffle 41 to close when it continues to rotate upward.

[0040] Reference Figure 2 and Figure 3 A rack 43 is fixedly connected to the lower surface of the pressing plate 21. A transmission wheel 431 meshing with the rack 43 is provided on the frame 1. A rotating shaft 44 is rotatably mounted on the frame 1, with one end of the rotating shaft 44 fixedly connected to the side wall of the transmission wheel 431. A push rod 45 is also rotatably mounted on the frame 1, capable of pushing the lower baffle 41 to close when it moves. A first connecting rod 46 is fixedly connected to the side wall of the rotating shaft 44, with the other end of the first connecting rod 46 connected to the end of the push rod 45 away from the lower baffle 41. A roller 47 is installed on the end of the push rod 45 near the lower baffle 41. The roller 47 facilitates the pushing action of the push rod 45 on the lower baffle 41 during its movement, reducing the probability of equipment damage.

[0041] After the abrasive cloth falls into the forming cylinder 2, as the number of divided abrasive cloths accumulates, the weight of the accumulated divided abrasive cloths gradually increases until it exceeds a set threshold. Under the gravity of the divided abrasive cloths, the lower baffle 41 tends to open and is fully opened under the tension of the return spring 42. Subsequently, the divided abrasive cloths in the forming cylinder 2 fall into the receiving cylinder 13 for storage. In the next movement, the pressing plate 21 drives the rack 43 to move linearly, which in turn drives the transmission wheel 431 and the rotating shaft 44 to rotate. Finally, the rotation of the rotating shaft 44 drives the push rod 45 to move down the lower baffle 41, closing the lower baffle 41. After the lower baffle 41 is closed, the return spring 42 tightens the lower baffle 41 again, and the next round of material collection begins in the forming cylinder 2.

[0042] Multiple forming cylinders 2, pressing cylinders 22, receiving cylinders 13, and opening / closing mechanisms 4 are provided. The arrangement of multiple forming cylinders 2, pressing cylinders 22, receiving cylinders 13, and opening / closing mechanisms 4 enables the simultaneous cutting and forming of multiple abrasive cloths, thereby improving work efficiency.

[0043] Reference Figure 2 and Figure 4 The pressing cylinder 22 is equipped with a linear actuator 23, which can be a cylinder, hydraulic cylinder, or electromagnetic push rod 45. A push plate 24 is fixedly connected to the drive rod of the linear actuator 23. A support plate 25 is fixedly connected to the bottom wall of the linear actuator 23, and a suction shell 26 is fixedly connected to the lower surface of the support plate 25. The push plate 24 is slidably disposed on the inner wall of the suction shell 26, and multiple ventilation holes 27 are opened on the push plate 24.

[0044] The linear actuator 23 and the pusher plate 24 are designed to push the abrasive cloth into the forming cylinder 2 after it is divided and formed, thereby improving the neatness of the abrasive cloth stacking in the forming cylinder 2.

[0045] The suction shell 26 and the vent 27 can adsorb the abrasive cloth during the process of the pusher plate 24 pushing the segmented abrasive cloth down, increasing the possibility of the abrasive cloth shaking on the lower surface of the pusher plate 24, and can blow the abrasive cloth away from the lower surface of the pusher plate 24 during the process of the pusher plate 24 moving upward, reducing the probability of the abrasive cloth being stacked messily in the forming cylinder 2 as the abrasive cloth moves upward with the pusher plate 24.

[0046] The implementation principle of the abrasive cloth forming and dividing device in this application embodiment is as follows: When it is necessary to form and divide abrasive cloth, the abrasive cloth is first transported to the lower part of the pressing mechanism 3 by the first conveyor belt 11. Then, the pressing mechanism 3 is started to drive the pressing plate 21 and the pressing cylinder 22 to move vertically. When the pressing cylinder 22 moves downward, the side wall cuts the abrasive cloth. The cut abrasive cloth falls into the forming cylinder 2 for collection. After being collected in the forming cylinder 2, it falls into the receiving cylinder 13 for storage and transportation. The forming and stacking of abrasive cloth are completed automatically, reducing the labor intensity of workers.
