Description

An adjustable-pitch corrugated roller feeder Technical Field

[0001] This utility model relates to the technical field of wave roller feeders, specifically to a wave roller feeder with adjustable roller spacing. Background Technology

[0002] Adjustable roller feeders are an important type of material conveying equipment. They can adapt to the material conveying needs of different thicknesses and materials by adjusting the distance between adjacent rollers. In the existing technology, roller distance adjustment mostly relies on manual mechanical locking or single-sided motor-driven screw fine adjustment. Although it can achieve basic adjustment function, it has significant limitations.

[0003] Traditional adjustment methods lack a multi-roller synchronous linkage mechanism, which leads to roller tilting or asynchronous displacement, causing uneven material transmission pressure, deviation, or even jamming, severely restricting the accuracy and efficiency of the equipment.

[0004] In view of this, an adjustable roller feeder is proposed. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that the adjustable roller gap wave roller feeder lacks a multi-roller synchronous linkage mechanism, which leads to the tilting or asynchronous displacement of the roller group, resulting in uneven material transmission pressure, deviation and jamming. The invention provides an adjustable roller gap wave roller feeder.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an adjustable roller feeder includes a base and two frames respectively fixedly connected to both sides of the base. The two frames are fixedly connected by connecting rods. A first electric push rod for driving the connecting rods to move up and down is fixedly connected to the base. Mounting plates are slidably arranged on both connecting rods. A fixed roller, a drive roller, and a follower roller are arranged between the two mounting plates. Rotating seats are rotatably arranged at both ends of the fixed roller, drive roller, and follower roller. Multiple rotating seats are slidably arranged on the mounting plates. Two first racks are fixedly connected to the top of the rotating seats on both sides of the drive roller. Two second racks are fixedly connected to the top of the rotating seats on both sides of the follower roller. Gears are rotatably connected to the two mounting plates. The two gears mesh with the first rack and second rack on the same side, respectively.

[0007] Preferably, a motor for driving the gear to rotate is fixedly connected to either of the two mounting plates.

[0008] Preferably, a second electric push rod is fixedly connected to each of the two mounting plates, and the extended end of the second electric push rod is fixedly connected to the rotating seat at the end of the drive roller.

[0009] Preferably, the top and bottom of the mounting plate are both fixedly connected to a first slider with a T-shaped cross-section, and the frame is provided with a first groove that matches the size of the first slider.

[0010] Preferably, the top and bottom of the rotating seat are both fixedly connected to a second slider with a T-shaped cross section, and the mounting plate is provided with a second groove that matches the size of the second slider.

[0011] Preferably, springs are fixedly connected to both sides of the rotating seats at both ends of the fixed roller, and the ends of the two springs away from the fixed roller are fixedly connected to the rotating seats of the driving roller and the following roller, respectively.

[0012] Preferably, a slide bar is fixedly connected to the frame, and the slide bar passes through the connecting rod.

[0013] Compared with the prior art, this utility model has the following beneficial effects:

[0014] 1. The adjustable roller feeder provided by this utility model uses the first electric push rod to drive the connecting rod to lift and lower, and the second electric push rod, gear and rack to adjust the lateral displacement, so as to realize the vertical and horizontal bidirectional adjustment of the active roller, follower roller and fixed roller, and ensure that multiple rollers can be adjusted synchronously to ensure uniform material transmission pressure.

[0015] 2. The adjustable roller feeder provided by this utility model uses a T-shaped slider and a groove design combined with a sliding rod through the connecting rod to form a double guiding and support system, which eliminates the risk of misalignment between the mounting plate and the rotating seat during the adjustment process, improves the overall structural rigidity, and is suitable for high-frequency and high-load working conditions.

[0016] 3. The adjustable roller feeder provided by this utility model automatically compensates for vibration and impact during adjustment and operation by setting up a fixed roller and a rotating seat for the active and follower rollers through a spring connection. This avoids instantaneous stress concentration caused by sudden changes in material thickness or external vibration. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Please refer to Figures 1-5.

[0027] This utility model relates to an adjustable roller gap corrugated roller feeder, comprising a base 1 and two frames 2 respectively fixedly connected to both sides of the base 1. The two frames 2 are fixedly connected by connecting rods 3. A first electric push rod 4 for driving the connecting rods 3 to move up and down is fixedly connected to the base 1. Mounting plates 6 are slidably mounted on both connecting rods 3. A fixed roller 7, a driving roller 8, and a follower roller 9 are arranged between the two mounting plates 6. Rotating seats are rotatably mounted at both ends of the fixed roller 7, driving roller 8, and follower roller 9. Multiple rotating seats are slidably mounted on the mounting plates 6. On the top of the rotating seats on both sides of the drive roller 8, two first racks 16 are fixedly connected, and two second racks 17 are fixedly connected to the top of the rotating seats on both sides of the follower roller 9. Gears 19 are rotatably connected to the two mounting plates 6. The two gears 19 are respectively meshed with the first rack 16 and the second rack 17 on the same side. This arrangement allows for the combination of vertical and horizontal adjustment to adapt to materials of different thicknesses and tensions. In addition, the gears 19 simultaneously mesh with the racks of the drive roller 8 and the follower roller 9 to avoid roller body skewing caused by unilateral drive.

[0028] One of the two mounting plates 6 is fixedly connected to a motor 15 for driving the rotation of the side gear 19. The single motor 15 drives the rack of the double-sided gear 19 to avoid synchronization error of the two motors 15.

[0029] Secondly, a second electric push rod 14 is fixedly connected to each of the two mounting plates 6. The extended end of the second electric push rod 14 is fixedly connected to the rotating seat at the end of the drive roller 8. The setting of the second electric push rod 14 can drive the first rack 16 to move the second rack 17 so that the follower roller 9 and the drive roller 8 can move away from or closer to the fixed roller 7 synchronously, which improves the convenience of roller spacing adjustment.

[0030] Furthermore, the top and bottom of the mounting plate 6 are fixedly connected to a first slider 10 with a T-shaped cross section, and the frame 2 is provided with a first groove 11 that matches the size of the first slider 10. This arrangement allows the mounting plate 6 to be assembled and disassembled simultaneously.

[0031] In addition, the top and bottom of the rotating seat are fixedly connected with a second slider 12 with a T-shaped cross section. The mounting plate 6 has a second groove 13 that matches the size of the second slider 12. This arrangement makes it easier to disassemble and assemble the wave roller during maintenance and cleaning. In addition, it can disperse stress and improve the device's resistance to deformation.

[0032] Furthermore, springs 18 are fixedly connected to both sides of the rotating seats at both ends of the fixed roller 7. The ends of the two springs 18 away from the fixed roller 7 are fixedly connected to the rotating seats of the drive roller 8 and the follower roller 9, respectively. This arrangement allows the rotating seats of the fixed roller 7 to be elastically connected to the rotating seats of the drive roller 8 and the follower roller 9 through the springs 18, so that the device can automatically absorb sudden changes in material thickness or external vibration energy during use, avoiding instantaneous overload.

[0033] Specifically, a slide bar 5 is fixedly connected to the frame 2. The slide bar 5 passes through the connecting rod 3. By adding the slide bar 5 through the connecting rod 3 to the frame 2, additional support is formed, which improves the overall rigidity and strength.

[0034] Working principle:

[0035] This adjustable-pitch corrugated roller feeder uses a first electric push rod 4 to drive the connecting rod 3 to vertically lift and lower, thereby adjusting the overall height of the mounting plate 6, fixed roller 7, drive roller 8, and follower roller 9. This allows for quick adaptation to the conveying needs of materials of different thicknesses. During horizontal adjustment, a single-sided motor 15 drives a gear 19 to synchronously mesh with the first rack 16 of the drive roller 8 and the second rack 17 of the follower roller 9, forcing the two rollers to move in opposite directions at equal intervals along the T-shaped second slide groove 13 on the mounting plate 6. This precisely controls the roller pitch, and the second electric push rod 14 assists in adjusting the drive roller 8. The displacement compensates for the transmission clearance; during the adjustment process, the mounting plate 6 is rigidly guided by the slide groove of the frame 2 through the T-shaped first slider 10, and the rotating seat is kept parallel to the slide groove of the mounting plate 6 through the T-shaped second slider 12. Combined with the constraint design of the slide rod 5 passing through the connecting rod 3, it ensures that the axis of the multi-roller is not skewed; at the same time, the spring 18 elastically connects the rotating seat of the fixed roller 7 with the active roller 8 and the follower roller 9, dynamically absorbing the sudden change in material thickness or external vibration energy, balancing the pressure difference between the rollers, and finally achieving high-precision adaptive adjustment in the vertical and horizontal directions.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
