Description

Technical Field

[0001] This utility model relates to the field of abrasive cloth production technology, and in particular to a suction roller device for the inlet of an oven. Background Technology

[0002] In the production of abrasive cloth, adhesive is typically applied only to one side of the substrate. The adhesive-coated or abrasive surface cannot be pressed with rollers to transmit power; only one side can exert force to force the cloth into the drying chamber. Currently, there are two main methods for transmitting power to abrasive cloth: one is using a negative pressure suction roller, and the other is using a suction plate. However, existing suction rollers are in direct contact with the suction chamber for extended periods, resulting in significant wear, difficulty in replacement, and inconvenient maintenance. Furthermore, air leakage exists between the suction roller and the suction chamber. In addition, loosely adhered abrasive particles are not easily removed and tend to fall off during subsequent processes, leading to a decrease in the quality of the abrasive cloth. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an oven inlet suction roller device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An oven inlet suction roller device includes a support frame. The top of the support frame is provided with a suction roller assembly, a fan, and a striking roller assembly. The suction roller assembly includes a suction roller, a drive shaft extending outward from the center of the suction roller, a suction chamber assembly at the front end of the drive shaft, and a drive sprocket installed on the rear end of the drive shaft with a tension sleeve.

[0006] In a preferred embodiment, a speed reducer motor is mounted on the support frame, and the output end of the speed reducer motor is connected to the transmission shaft via a coupling to control the rotation of the transmission shaft.

[0007] The suction chamber assembly includes a suction chamber and a friction plate. The rotation center of the suction chamber is sleeved on the drive shaft via a ball bearing, and the friction plate is mounted on the plate surface of the suction chamber facing the suction roller.

[0008] In a preferred embodiment, the friction plate is selected from POM acetal copolymer.

[0009] In a preferred embodiment, the suction chamber is designed as a fan-shaped plate, and suction adjustment bolts are provided on the suction chamber outward.

[0010] In a preferred embodiment, a suction adjustment plate is fixedly installed on the support frame, and an arc-shaped groove is formed on the suction adjustment plate, with the front end of the suction adjustment bolt extending into the arc-shaped groove.

[0011] The impact roller assembly includes an impact roller shaft, with end plates on both sides of the shaft. The end plates are fixed together by three connecting rods. A driven sprocket is mounted on the shaft via a tensioning sleeve. The driving sprocket and the driven sprocket are aligned and connected by a chain belt.

[0012] In a preferred embodiment, both ends of the impact roller shaft are inserted into bearing seats, and both bearing seats are fixedly mounted on the support frame.

[0013] In a preferred embodiment, the impact roller is formed by two end plates and three connecting rods disposed between the two end plates, with the three connecting rods distributed in a triangular position on the surface of the end plates.

[0014] The beneficial effects of this utility model are:

[0015] 1. It reduces wear on the suction chamber, has lower wear costs for the friction plate, is easy to maintain, and reduces the gap between the suction chamber and the suction roller, thus preventing air leakage.

[0016] 2. The rotating impact roller shakes off loose sand from the sandpaper, preventing it from falling off during later processing and ensuring the quality of the sandpaper.

[0017] 3. The suction chamber is connected to the suction adjustment plate through the suction adjustment bolt, so as to achieve adsorption between the suction roller and the sandpaper for a period of time. At the same time, the suction chamber has multiple arc-shaped threaded holes, which can provide a certain range of adjustment.

[0018] The suction roller device proposed in this solution solves the problems of inconvenient maintenance of suction rollers during long-term operation and air leakage in the suction plate, which affects the production quality of sandpaper. It can effectively reduce the wear of the suction chamber and avoid air leakage. When sandpaper is glued with sand, it can knock off the loosely adhered sand, ensuring the production quality of sandpaper products. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In this embodiment, refer to Figure 1-3 A suction roller device for an oven inlet includes a support frame 1, and a suction roller assembly 2, a fan 3, and a striking roller assembly 5 are disposed on the top of the support frame 1, wherein:

[0025] The suction roller assembly 2 includes a suction roller 22. The outer wall of the suction roller 22 is provided with suction holes and a number of axial suction channels are distributed in a ring. Every two rows of axial suction holes are connected to the corresponding axial suction channels.

[0026] The drive shaft 21 extends outward from the center of the suction roller 22. The front end of the drive shaft 21 is provided with a suction chamber assembly 6, and the rear end of the drive shaft 21 is fitted with a drive sprocket 23.

[0027] A reducer motor 4 is mounted on the support frame 1. The output end of the reducer motor 4 is connected to the drive shaft 21 via a coupling and controls the rotation of the drive shaft 21. The reducer motor 4 controls the rotation of the suction roller 22.

[0028] The suction chamber assembly 6 includes a suction chamber 61 and a friction plate 63. The rotation center of the suction chamber 61 is mounted on the drive shaft 21 via a ball bearing 62. The friction plate 63 is mounted on the plate surface of the suction chamber 61 facing the suction roller 22. The suction chamber 61 is in close contact with the end face of the suction roller 22 near the friction plate 63. The friction plate 63 has a suction groove for connecting with the axial suction channel. The suction groove is arc-shaped and communicates with the suction chamber 61. The suction chamber 61 is connected to the fan 3 through a pipe. The fan 3 draws air to create a negative pressure in the suction chamber 61.

[0029] In this embodiment, the suction chamber 61 does not directly contact the suction roller 22; a friction plate 63 is sandwiched between them. The friction plate 63 is made of high-strength, wear-resistant POM acetal copolymer. During prolonged operation of the suction roller 22, the friction plate 63 is the primary material that wears, and it does not affect the suction chamber 61. Subsequent maintenance only requires replacing the friction plate 63, making maintenance convenient. Furthermore, the friction plate 63's close contact with both sides of the suction roller 22 and the suction chamber 61 reduces the gap between them, thus minimizing air leakage.

[0030] The impact roller assembly 5 includes an impact roller shaft 51, with both ends of the impact roller shaft 51 inserted into bearing seats 55, and both bearing seats 55 are fixedly mounted on the support frame 1.

[0031] The impact roller shaft 51 has end plates 52 on both sides, and the end plates 52 are fixed together by three connecting rods 53. The impact roller is formed by the two end plates 52 and the three connecting rods 53 between the two end plates 52. The three connecting rods 53 are distributed in a triangular position on the surface of the end plates 52. With this design, the sandpaper is continuously pushed upward, so that the sand that is not firmly stuck to the sandpaper can be automatically removed.

[0032] A driven sprocket 54 is mounted on the shaft of the impact roller shaft 51 via a shrink sleeve. The driving sprocket 23 is aligned with the driven sprocket 54 and is connected to the drive via a chain belt.

[0033] Finally, the suction chamber 61 is designed as a fan-shaped plate, and a suction adjustment bolt 8 is provided on the suction chamber 61 facing outward. A suction adjustment plate 7 is fixedly installed on the support frame 1, and an arc-shaped groove 81 is opened on the suction adjustment plate 7. The front end of the suction adjustment bolt 8 extends into the arc-shaped groove 81. The suction chamber 61 is connected to the suction adjustment plate 7 through the suction adjustment bolt 8, so as to realize the adsorption between the suction roller 22 and the sandpaper for a period of time. At the same time, the suction chamber 61 has multiple arc-shaped threaded holes, which can provide a certain range of adjustment.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
