[0002] Roller presses are widely used as key conveying equipment in many fields such as industrial production and logistics transportation. However, the structural design of traditional roller presses has obvious limitations. The roller spacing is usually fixed, which makes it difficult for traditional roller presses to meet diverse conveying needs when conveying items of different sizes and specifications. If the size of the conveyed items does not match the roller spacing, unstable conveying and easy dropping of items may occur, seriously affecting conveying efficiency and item quality. Utility Model Content

[0003] The purpose of this invention is to provide a roller bed with adjustable roller spacing, which can adjust the spacing between the rollers to meet the conveying needs of items of different sizes, improve the versatility and adaptability of the roller bed, and can quickly and easily restore it to a suitable state, ensuring that it is always in good working condition. It ensures that the roller bed can quickly resume normal operation after the spacing is adjusted, reducing downtime and debugging difficulty caused by adjustment, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An adjustable roller bed includes a frame, which comprises two parallel support plates and a support base fixedly mounted on the bottom of the support plates. First bearing seats are bolted to both support plates, and a drive roller is fixedly mounted between the two first bearing seats. First oblong holes are formed on both support plates, and multiple corresponding second bearing seats are bolted to both support plates and mounted through the first oblong holes. A driven roller is fixedly mounted between two corresponding second bearing seats. A drive motor is fixedly mounted on the support base. The output shaft of the drive motor is connected to the roller shaft of the drive roller via a first transmission mechanism. The roller shaft of the drive roller and the roller shaft of the adjacent driven roller, as well as the roller shafts of two adjacent driven rollers, are all connected via a second transmission mechanism. An adjustment mechanism for adjusting the tension of the second transmission mechanism is provided on the support base.

[0006] Preferably, the first transmission mechanism includes two first synchronous pulleys and a first synchronous belt. The two first synchronous pulleys are respectively fixedly connected to the output shaft of the drive motor and the roller shaft of the drive drum, and the two first synchronous pulleys are connected by the first synchronous belt.

[0007] Preferably, the second transmission mechanism includes two second synchronous pulleys and a second synchronous belt. The two second synchronous pulleys are respectively fixedly connected to the roller shafts of the two driven rollers, and the two second synchronous pulleys are connected by the second synchronous belt.

[0008] Preferably, the adjustment mechanism includes a mounting plate, an adjustment shaft, and a tensioning wheel. The mounting plate is fixedly connected to the support base frame. The mounting plate has multiple vertically arranged second oblong holes. The adjustment shaft is mounted on the mounting plate through a locking nut and the second oblong holes. The tensioning wheel is fixedly connected to the adjustment shaft. The second synchronous belt passes through the tensioning wheel.

[0009] Preferably, a protective cover is fixedly installed between the two support plates and the support base.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This adjustable roller spacing roller bed uses a first oblong hole in the support plate and bolts to install a second bearing seat. The position of the second bearing seat can be adjusted within the range of the first oblong hole. Since the driven roller is fixedly installed between two corresponding second bearing seats, adjusting the position of the second bearing seats changes the spacing between the driven rollers, thus meeting the conveying needs of items of different sizes and improving the versatility and adaptability of the roller bed. An adjustment mechanism on the support base is used to adjust the tension of the second transmission mechanism. After changing the spacing between the driven rollers, the tension of the second transmission mechanism can be quickly and easily adjusted through the adjustment mechanism to restore it to a suitable state, ensuring that the second transmission mechanism is always in good working condition. This ensures that the roller bed can quickly resume normal operation after the spacing is adjusted, reducing downtime and debugging difficulty caused by adjustments. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-4This utility model provides a roller bed with adjustable roller spacing, including a frame 1. The frame 1 includes two parallel support plates 101 and a support base 102 fixedly installed at the bottom of the support plates 101. First bearing seats 2 are fixedly installed on both support plates 101 by bolts. A drive roller 3 is fixedly installed between the two first bearing seats 2. First waist-shaped holes 1011 are opened on both support plates 101. Multiple corresponding second bearing seats 4 are installed on both support plates 101 by bolts and the first waist-shaped holes 1011. A driven roller 5 is fixedly installed between two corresponding second bearing seats 4. A drive motor 6 is fixedly installed on the support base 102. The output shaft of the drive motor 6 is connected to the roller shaft of the drive roller 3 through a first transmission mechanism 7. The roller shaft of the drive roller 3 and the roller shaft of the adjacent driven roller 5, as well as the roller shafts of two adjacent driven rollers 5, are all connected through a second transmission mechanism 8. An adjustment mechanism 9 for adjusting the tension of the second transmission mechanism 8 is provided on the support base 102.

[0022] The adjustable roller spacing roller bed has a first oblong hole 1011 on the support plate 101, and a second bearing seat 4 is installed using bolts and the first oblong hole 1011. This allows the position of the second bearing seat 4 to be adjusted within the range of the first oblong hole 1011. Since the driven roller 5 is fixedly installed between two corresponding second bearing seats 4, adjusting the position of the second bearing seat 4 can change the spacing between the driven rollers 5, thereby meeting the conveying needs of items of different sizes and improving the versatility and adaptability of the roller bed. The adjustment mechanism 9 set on the support base 102 is used to adjust the tension of the second transmission mechanism 8. After changing the spacing between the driven rollers 5, the tension of the second transmission mechanism 8 can be quickly and easily adjusted through the adjustment mechanism 9 to restore it to a suitable state, ensuring that the second transmission mechanism 8 is always in good working condition. This ensures that the roller bed can quickly resume normal operation after the spacing is adjusted, reducing downtime and debugging difficulty caused by adjustment.

[0023] The first transmission mechanism 7 includes two first synchronous pulleys 701 and a first synchronous belt 702. The two first synchronous pulleys 701 are fixedly connected to the output shaft of the drive motor 6 and the roller shaft of the drive roller 3, respectively. The two first synchronous pulleys 701 are connected by the first synchronous belt 702. The first transmission mechanism 7 adopts the structure of two first synchronous pulleys 701 and a first synchronous belt 702. The synchronous belt drive has the advantages of accurate and stable transmission, which can ensure that the power of the drive motor 6 is accurately and stably transmitted to the drive roller 3, so that the drive roller 3 rotates at a predetermined speed and direction, providing reliable power support for the smooth transport of goods.

[0024] The second transmission mechanism 8 includes two second synchronous pulleys 801 and a second synchronous belt 802. The two second synchronous pulleys 801 are respectively fixedly connected to the roller shafts of the two driven rollers 5. The two second synchronous pulleys 801 are connected by the second synchronous belt 802. The second transmission mechanism 8 connects adjacent driven rollers 5 through the two second synchronous pulleys 801 and the second synchronous belt 802, so that the adjacent driven rollers 5 can rotate synchronously. This ensures that the force on each part of the item is uniform during the conveying process, avoids the item tilting or damage due to the difference in roller speed, and improves the quality of item conveying. When adjusting the distance between the driven rollers 5, only the length of the second synchronous belt 802 needs to be adjusted accordingly to ensure that the transmission mechanism works normally and the transmission effect is not affected by the distance adjustment.

[0025] The adjusting mechanism 9 includes a mounting plate 901, an adjusting shaft 902, and a tensioning wheel 903. The mounting plate 901 is fixedly connected to the support base 102. The mounting plate 901 has multiple vertically arranged second oblong holes 9011. The adjusting shaft 902 is mounted on the mounting plate 901 through a locking nut and the second oblong holes 9011. The tensioning wheel 903 is fixedly connected to the adjusting shaft 902. The second synchronous belt 802 passes through the tensioning wheel 903. After changing the distance between the driven rollers 5, the tensioning wheel 903 in the adjusting mechanism 9 can adjust the tension of the second synchronous belt 802 by adjusting the position of the adjusting shaft 902 in the second oblong holes 9011 of the mounting plate 901, so that it returns to a suitable state. This ensures that the second synchronous belt pulley 801 and the second synchronous belt 802 are always in good working condition, and ensures that the roller bed can quickly resume normal operation after the distance is adjusted, reducing downtime and debugging difficulty caused by adjustment.

[0026] Protective covers 10 are fixedly installed between the two support plates 101 and the support base frame 102. These covers prevent workers from accidentally contacting moving parts such as rollers and transmission mechanisms during operation, thus avoiding accidents and ensuring the safety of workers. They also serve to prevent dust and debris from entering the roller bed and protect the roller bed components from damage. An extended protective plate 11 for shielding the drive motor 6 is fixedly installed on the protective cover 10 near the drive motor 6 by bolts, which further enhances the protection of the drive motor 6. Several fixed shafts 12 are fixedly connected to both protective covers 10. Rollers 13 are installed on the fixed shafts 12 through bearings. The rollers 13 play an auxiliary role in the material conveying process. When the material comes into contact with the rollers 13, the rollers 13 can roll, preventing the material from falling off the rollers and allowing it to pass through the roller bed more smoothly, further improving the efficiency of material conveying.

[0027] When the adjustable roller spacing roller bed is in operation, firstly, according to the size of the item to be conveyed, the position of the second bearing seat 4 is adjusted in the first oblong hole 1011 of the support plate 101 in the frame 1 by bolts, thereby changing the spacing of the driven rollers 5 between the two corresponding second bearing seats 4 to adapt to the size of the item. Next, if adjusting the spacing of the driven rollers 5 affects the second transmission mechanism 8, the tension of the second synchronous belt 802 is adjusted using the adjusting mechanism 9: loosen the locking nut on the adjusting shaft 902 in the adjusting mechanism 9, move the position of the adjusting shaft 902 in the second oblong hole 9011 of the mounting plate 901, so that the tensioning wheel 903 installed on the adjusting shaft 902 drives the second synchronous belt 802 to a suitable tension, and then tighten the locking nut to fix the adjusting shaft 902. Then, the drive motor 6 on the support base 102 is started. Its output shaft transmits power to the drive roller 3 through the first transmission mechanism 7, which consists of the first synchronous pulley 701 and the first synchronous belt 702. The drive roller 3 then drives the driven roller 5 to rotate synchronously through the second transmission mechanism 8, which consists of the second synchronous pulley 801 and the second synchronous belt 802. During the material conveying process, the protective cover 10 installed on the frame 1 prevents personnel from contacting the moving parts and serves as a dust and debris protection function. The extended protective plate 11 on the protective cover 10 near the drive motor 6 is fixed with bolts to enhance the protection of the drive motor 6. The rollers 13 installed on the fixed shafts 12 on the two protective covers 10 roll when the materials come into contact, helping the materials to pass smoothly through the roller bed.
