Description

Technical Field

[0001] This patent relates to the field of paper roller transport technology, specifically a paper roller transport frame with protective and shock-absorbing functions. Background Technology

[0002] In the paper feeding mechanisms of equipment such as electrostatic copiers, laser printers, plain paper fax machines, inkjet printers, and ATMs, various paper feed rollers are installed. Examples of such paper feed rollers include those that rotate while in contact with paper (including plastic film, etc.) and feed paper through friction, such as feed rollers, conveyor rollers, pressure rollers, and paper discharge rollers.

[0003] During transportation, paper rollers need to be fixed on a vertical transport frame. Generally, a locking structure is installed in the hole of the vertical plate to fix the bearing at the end of the paper roller. However, as transportation progresses, road conditions cause bumps, which will directly exert force on the outer ring of the bearing. Moreover, the force is radial relative to the bearing, which can easily damage or even cause the bearing to fall off. In addition, fixing the bearing on the paper roller will cause the paper roller to rotate frequently during transportation, which will cause premature wear of the bearing and the paper roller. Therefore, we propose a paper roller transport frame with protective shock absorption function. Utility Model Content

[0004] The purpose of this patent is to provide a paper roller transport rack with protective and shock-absorbing functions to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this patent provides the following technical solution: a paper roller transport rack with protective and shock-absorbing functions, including a base, a first upright plate fixedly installed on the top left side of the base, an adjustment mechanism provided on the top right side of the base, and a second upright plate connected to the top right side of the base through the adjustment mechanism. Both the first and second upright plates are provided with square holes, elastic members are fixedly installed on the four sides of the inner sidewall of the square holes, a square column is provided in the square holes, the free ends of the four elastic members are fixedly installed on the four sides of the outer sidewall of the square column, and a slot is provided at the inner end of the square column.

[0006] The elastic element includes a spring, and connecting plates are fixedly installed at both the upper and lower ends of the spring. One end of a universal joint is fixedly installed on the outer side of the connecting plate. The other end of one universal joint is fixedly installed on the inner wall of the square hole, and the other end of the other universal joint is fixedly installed on the outer wall of the square column.

[0007] Preferably, the adjusting mechanism includes a fixed ring and a screw. The bottom end of the fixed ring is integrally formed on the top right end of the base. A bearing is fixedly installed on the inner side wall of the fixed ring. The side wall of the screw is fixedly installed on the inner side wall of the inner ring of the bearing. A threaded hole is provided on the lower right side of the second upright plate. The threaded hole is screwed to the screw. Limiting members are provided on both the front and rear sides of the bottom of the second upright plate. The limiting members are connected to the top of the base.

[0008] Preferably, the limiting component includes a limiting wheel, and the bottom front and rear sides of the second upright plate are provided with mounting grooves. The limiting wheel is connected to the mounting groove through a rotating shaft. The top front and rear sides of the base are provided with wheel grooves, and the bottom end of the limiting wheel is rolled and installed in the wheel groove.

[0009] Preferably, the bottom of the second upright plate does not contact the top of the base.

[0010] Preferably, the slot has an expansion groove at the opening edge.

[0011] Preferably, the inner wall of the slot is fitted with a rubber sleeve.

[0012] Compared with the prior art, the beneficial effects of this patent are as follows: This patent has a first upright plate and a second upright plate installed on both sides of the top of the base. The first upright plate and the second upright plate are provided with square holes. Elastic elements are installed on the four sides of the inside of the square holes. The four elastic elements are respectively fixed on the four sides of the side wall of the square column. The rotating shafts at both ends of the paper roller can be inserted into the slots of the square column. The second upright plate can be adjusted left and right by the adjustment mechanism, which facilitates the assembly of the paper roller with the overall transport frame. Setting the installation position of the paper roller on the rotating shaft avoids severe internal wear of the bearing. Moreover, the force of vehicle vibration during transportation can be buffered by the elastic elements, avoiding direct action on the paper roller, thus providing a protective effect between the components of the paper roller.

Detailed Implementation

[0017] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0018] Please see Figure 1 , Figure 2 and Figure 3 This patent provides a technical solution: a paper roller transport rack with protective and shock-absorbing functions, including a base 1, a first upright plate 2 fixedly installed on the top left side of the base 1, an adjustment mechanism provided on the top right side of the base 1, a second upright plate 3 connected to the top right side of the base 1 through the adjustment mechanism, square holes 4 provided on both the first upright plate 2 and the second upright plate 3, elastic members 5 fixedly installed on the four sides of the inner sidewall of the square hole 4, a square column 6 provided in the square hole 4, the free ends of the four elastic members 5 fixedly installed on the four sides of the outer sidewall of the square column 6, and a slot 7 provided at the inner end of the square column 6;

[0019] The shape of slot 7 and Figure 1 The rotating shafts at the ends of the middle paper rollers have the same shape and can be square.

[0020] The elastic element 5 includes a spring 8. Both the upper and lower ends of the spring 8 are fixedly mounted with connecting plates 9. One end of a universal joint 10 is fixedly mounted on the outer side of the connecting plate 9. The other end of one universal joint 10 is fixedly mounted on the inner wall of the square hole 4, and the other end of the other universal joint 10 is fixedly mounted on the outer wall of the square column 6.

[0021] If the two ends of the spring 8 are directly fixed to the inner wall of the square hole 4 and the outer wall of the square post 6 respectively, the force generated when the vehicle body shakes will cause the spring 8 to tilt. The torsional force generated by the tilt will directly act on the fixed connection position at the end of the spring 8. Over time, the connection position of the spring 8 will be easily damaged and fall off, thus losing its buffering effect.

[0022] By setting the universal joint 10 to connect the installation position with the spring 8, the spring 8 can move and twist smoothly in different directions, avoiding damage or even falling off.

[0023] Specifically, the adjustment mechanism includes a fixed ring 11 and a screw 13. The bottom end of the fixed ring 11 is integrally formed on the top right end of the base 1. A bearing 12 is fixedly installed on the inner side wall of the fixed ring 11. The side wall of the screw 13 is fixedly installed on the inner side wall of the inner ring of the bearing 12. A threaded hole 14 is provided on the lower right side of the second upright plate 3. The threaded hole 14 is screwed to the screw 13. Limiting members are provided on both the front and rear sides of the bottom of the second upright plate 3. The limiting members are connected to the top of the base 1.

[0024] The aforementioned adjustment mechanism is similar to a traditional lead screw device. By rotating the screw 13, the second vertical plate 3 is limited by the limiting member (so that it can only move left and right), which in turn drives the second vertical plate 3 to move left and right.

[0025] Specifically, the limiting component includes a limiting wheel 15. The bottom of the second upright plate 3 is provided with mounting grooves 16 on both the front and rear sides. The limiting wheel 15 is connected to the mounting groove 16 through a rotating shaft. The top of the base 1 is provided with wheel grooves 17 on both the front and rear sides. The bottom end of the limiting wheel 15 is rolled and installed in the wheel groove 17.

[0026] In traditional lead screw systems, the limiting mechanism mostly slides within the guide rail via a slider. This is a sliding limit, which causes severe wear between components and requires frequent replacement. In particular, the sliding limit mechanism in a manual lead screw system has high resistance and is inconvenient to operate. However, by rolling the bottom end of the limiting wheel 15 within the wheel groove 17, the limiting becomes a rolling limit, which can greatly reduce friction and decrease the resistance of manual operation.

[0027] Specifically, the bottom of the second upright plate 3 does not contact the top of the base 1.

[0028] Specifically, an expansion groove 18 is provided at the opening edge of slot 7.

[0029] The expansion groove 18 is designed to facilitate the insertion of the rotating shaft at the end of the paper roller into the slot 7.

[0030] Specifically, a rubber sleeve 19 is embedded in the inner wall of the slot 7.

[0031] The rubber sleeve 19 is designed to support the rotating shaft of the paper roller and the square post 6, thereby further reducing and buffering the force.

[0032] Working principle: Mounting holes can be set at the four corners of the base 1. The base 1 can be fixed in the transport compartment by bolts. Rotate the screw 13 to drive the second upright plate 3 to move to the right. Then insert the rotating shaft at the left end of the paper roller into the slot 7 of the left square column 6. Then reverse the screw 13 to drive the second upright plate 3 to move to the left. It is connected to the rotating shaft at the right end of the paper roller through the slot 7 of the right square column 6. The bumpy force generated by the vehicle transportation can be buffered and offset by the spring 8 and the rubber sleeve 19 to avoid direct action on the paper roller.
