[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0032] In the field of fruit bagging in agriculture, bagging effectively prevents damage from adverse natural and agricultural environments, providing excellent protection for fruit growth and significantly improving the yield of high-quality fruit. Currently, peach bagging primarily uses individual paper bags. In automated bagging operations, this method requires repeated bag removal, making the process relatively complex. Roller-type feeding mechanisms, however, can provide continuous paper bag supply, facilitating automated bagging. In roller-type fruit bagging equipment, the speed and ease of roller replacement directly determine the efficiency of automated bagging. A well-designed roller replacement mechanism can significantly reduce the time spent changing materials and decrease the size of the roller replacement mechanism, making it a crucial component for achieving automated roller-type fruit bagging.

[0033] In the field of quick roller change technology, the design of quick roller change mechanisms is commonly used in industrial automation equipment, production line equipment, printing presses, conveyor belt systems, and other equipment that requires frequent roller changes. Its main purpose is to improve equipment maintenance efficiency, reduce downtime, and enhance the flexibility and operational safety of the production line. In fruit bagging roller feeding equipment, paper bag rollers require even more frequent replacement. During automated fruit bagging, paper bag rollers are consumable materials, requiring not only rapid replacement with new rollers but also efficient unloading of used rollers.

[0034] This invention aims to meet the requirements of frequent material replacement of paper bag rollers in roller-type fruit bagging equipment, while simultaneously removing old material. As part of the feeding mechanism, the roller changing mechanism not only needs to be fully functional, easy to use, stable, and efficient, while minimizing the power source, but also requires a compact structure that does not occupy excessive installation space.

[0035] This invention provides a quick roller replacement device for roller-type fruit bagging equipment. The rotating replacement mechanism of this invention can rotate clockwise or counterclockwise. Utilizing a reasonable structural arrangement, it simultaneously replaces the material in the new roller and unloads the material from the old roller, integrating the replacement and unloading actions into a single cycle. This invention uses a rotating block return spring; through spring compression or rebound, the rotating replacement mechanism automatically rotates counterclockwise, which is simple and reliable. This invention includes upper and lower limit blocks to restrict the rotation range of the rotating replacement mechanism, preventing it from exceeding the range and ensuring the reliability of the roller replacement process. The roller replacement of this invention requires no power source and can be completed quickly without disassembling the mounting components. The integrated roller replacement design of this invention significantly improves the working efficiency of equipment that requires frequent roller material changes. As an independent module, this device, after appropriate scaling, can be easily embedded into various roller-type feeding mechanisms, exhibiting a certain degree of versatility.

[0036] Example 1

[0037] like Figures 1-5 As shown, a quick roller replacement device for a roller-type fruit bagging equipment is disclosed. The device is used for replacing new rollers and old rollers. The device includes a mounting base plate 1, a rotating replacement mechanism, a roller inlet 3, a roller outlet 4, and a rotating block rotation groove 5. The rotating block rotation groove 5 is installed in the mounting base plate 1, and the rotating replacement mechanism is installed in the rotating block rotation groove 5. The roller inlet 3 and the roller outlet 4 are both installed in the mounting base plate 1. The roller inlet 3 and the roller outlet 4 are respectively in contact with the rotating replacement mechanism, and the old roller is installed in the rotating replacement mechanism.

[0038] The new roller enters the device from the roller inlet 3, causing the rotation replacement mechanism to rotate in the rotating block groove 5. The new roller gradually enters the rotation replacement mechanism and replaces the old roller. The old roller disengages from the roller outlet 4, completing the replacement.

[0039] In this embodiment, the new roller enters the device through roller inlet 3. As the new roller goes deeper, it squeezes the rotary replacement mechanism, causing it to rotate clockwise. This causes the new roller to enter the rotary replacement mechanism. At the same time, due to the clockwise rotation, the rotary replacement mechanism releases the old roller from its fixation, allowing it to detach freely. When the new roller enters the rotary replacement mechanism, the rotary replacement mechanism rotates counterclockwise to reset itself and fixes the new roller.

[0040] The device also includes a rotating block reset spring mounting groove 101, a stepped hole 103, and a rotating block shaft hole 104. The rotating block reset spring mounting groove 101, the stepped hole 103, and the rotating block shaft hole 104 are respectively installed in the rotating block rotation groove 5. The stepped hole 103 and the rotating block shaft hole 104 are coaxial.

[0041] The device also includes a reset spring mounting hole 102 and a roller unlocking cam groove 105. The reset spring mounting hole 102 is installed in the rotating block reset spring mounting groove 101, and the roller unlocking cam groove 105 is installed on the stepped hole 103.

[0042] The rotating replacement mechanism includes a rotating block 2, a roller inlet / outlet slot 201, and two locking block mounting shaft holes 202. The roller inlet / outlet slot 201 is mounted on the rotating block 2, and the locking block mounting shaft holes 202 are respectively mounted on the roller inlet / outlet slot 201 and perpendicular to it. The two locking block mounting shaft holes 202 are respectively close to the roller inlet 3 or the roller outlet 4.

[0043] The rotation replacement mechanism also includes a locking block 207 on the roller shaft, a locking block reset torsion spring 208, and an upper locking block mounting shaft 209. The upper locking block mounting shaft 209 is installed in the locking block mounting shaft hole 202, and the locking block 207 on the roller shaft is connected to the upper locking block mounting shaft 209 through the locking block reset torsion spring 208.

[0044] The rotational replacement mechanism also includes a lower locking block pin 210, a lower roller locking block 211, and a lower locking mounting shaft 212. The lower locking mounting shaft 212 is installed in the locking block mounting shaft hole 202. The lower roller locking block 211 is connected to the lower locking mounting shaft 212 through a locking block reset torsion spring 208. The lower locking block pin 210 is installed on the lower roller locking block 211.

[0045] The roller unlocking cam groove 105 is located on the rotation path of the locking block pin 210.

[0046] The rotating replacement mechanism also includes a limiting boss 205 and a rotating block shaft core 206. The limiting boss 205 and the rotating block shaft core 206 are mounted on the rotating block 2. The rotating block shaft core 206 is mounted on the rotating block shaft hole 104. The limiting boss 205 is mounted on the side of the rotating block shaft core 206.

[0047] The rotating replacement mechanism also includes a rotating block reset spring 8, a reset spring mounting terminal 203, and a trigger eccentric block 204. The trigger eccentric block 204 is mounted on the rotating block 2, and the reset spring mounting terminal 203 is mounted on the trigger eccentric block 204. The rotating block reset spring 8 is connected to the reset spring mounting terminal 203 and the reset spring mounting hole 102 respectively and is mounted in the rotating block reset spring mounting groove 101.

[0048] The device also includes an upper limit stop 6 and a lower limit stop 7, which are respectively mounted on the mounting base plate 1.

[0049] In this embodiment, the device includes a mounting base plate 1, a rotating block 2, a roller inlet 3, a roller outlet 4, a rotating block rotation groove 5, an upper limit stop 6, a lower limit stop 7, and a rotating block return spring 8. The rotating block 2 is installed in the rotating block rotation groove 5 on the mounting base plate 1; the upper locking block 207 on the roller shaft is installed in the locking block mounting shaft hole 202 opened on the back of the rotating block 2, and can rotate around the upper locking block mounting shaft 209; the lower locking block 211 on the roller shaft is installed in another set of locking block mounting shaft holes 202 opened on the back of the rotating block, and the lower locking block mounting shaft 212 and the upper locking block mounting shaft 209 are arranged parallel to each other in the same plane.

[0050] The device is a complete quick-change roller module, typically consisting of two quick-change roller modules installed opposite each other for roller replacement. In the initial state, under the elastic force of the rotating block return spring 8, the trigger eccentric block 204 contacts the upper limit stop block 6, placing the rotating block 2 in its initial position. The locking block 207 on the roller shaft is pushed upwards by the locking block return torsion spring 208, limiting the roller shaft in the direction of the roller inlet 3. Simultaneously, the lower locking block pin 10 on the lower surface of the lower locking block 211 contacts the upper surface of the stepped hole 103, overcoming the torsional force of the locking block return torsion spring 208 and being pushed upwards, thus limiting the roller shaft in the direction of the roller outlet 4. In the initial state, both the upper locking block 207 and the lower locking block 211 protrude from the roller inlet / outlet slot 201, thus restricting the old roller and preventing it from moving.

[0051] When replacing materials on the old and new rollers, the new roller is pushed in parallel from the roller inlet 3. When it comes into contact with the inclined surface of the trigger eccentric block 204, the rotating block 2 rotates clockwise under the force of the new roller shaft and the inclined surface. At this time, the rotating block reset spring 8 is gradually compressed.

[0052] Furthermore, when the rotating block 2 gradually rotates until the roller inlet / outlet slot 201 is parallel to the roller inlet 3, the roller inlet / outlet slot 201 is connected to the roller inlet 3, and the lower locking block pin 210 gradually moves from contact with the upper surface of the stepped hole 103 to contact with the roller unlocking cam groove 105.

[0053] Further, when the rotating block 2 rotates to the point where the trigger eccentric block 204 contacts the lower limit stop block 7, the rotation stops. At this time, the new roller shaft enters the roller inlet / outlet slot 201, and the lower locking block pin 210 is fully inserted into the slot of the roller unlocking cam groove 105. Under the action of the locking block reset torsion spring 208, the lower locking block 211 of the roller shaft rotates downward, and the lower surface of the lower locking block 211 of the roller shaft contacts the upper surface of the stepped hole 103, thus completing the unlocking of the old roller shaft that is currently working on the roller outlet 4 side. Then, without the limiting effect of the lower locking block 211 of the roller shaft, the old roller loses its constraint and exits from the roller inlet / outlet slot 201, and then exits through the roller outlet 4. At this point, the unloading of the old roller material is completed.

[0054] Furthermore, when the new roller is pushed in until it contacts the inclined surface 213 of the upper locking block, the locking block 207 on the roller shaft is subjected to a vertically downward force under the action of the new roller, thus starting to rotate. When the inclined surface 213 of the upper locking block rotates to be parallel to the upper surface of the roller inlet / outlet slot 201, the locking block 207 on the roller shaft will not hinder the movement of the new roller. At the same time, since the old roller has been removed from the device, the new roller can smoothly enter the new working position.

[0055] Furthermore, after the new roller shaft enters the working position, it becomes coaxial with the rotating block shaft core 206. At this time, the torque generated by the contact between the new roller shaft and the side of the roller inlet / outlet slot 201 disappears. The rotating block 2 rotates counterclockwise under the elastic force of the rotating block return spring 8 until the trigger eccentric block 204 contacts the upper limit stop block 6 again. At this time, the rotating block 2 returns to the initial position. After the locking block 207 on the roller shaft disengages from the new roller shaft, under the torque of the locking block return torsion spring 208, the locking block 207 on the roller shaft returns to the lifted position, re-limiting the new roller on the roller inlet 3 side.

[0056] Furthermore, as the rotating block 2 gradually rotates to its initial position, the lower locking block pin 210 gradually disengages from the roller unlocking cam groove 105 and re-engages with the stepped hole 103. Under the contact thrust of the stepped hole 103, the lower locking block 211 of the roller shaft is pushed up again, completing the limiting of the new roller on the roller outlet 4 side. At this point, the replacement of the new roller and the unloading of the old roller are completed, and all components return to their initial working positions to await the next roller material replacement operation.

[0057] Since the roller unlocking cam groove 105 and the lower locking block pin 210 need to be used together, the roller unlocking cam groove 105 should be on the path of the lower locking block pin 210 when it rotates, so that the lower locking block pin 210 can smoothly enter or leave the roller unlocking cam groove 105, so as to realize the lifting or rebound of the lower locking block 211 on the roller shaft.

[0058] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
