[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0032] In the field of agricultural fruit bagging, fruits can effectively avoid damage from adverse natural environments and agricultural production environments after bagging, providing good protection for the growth of fruits, thereby greatly improving the yield rate of fruits. At present, a single independent paper bag is mainly used in the process of peach bagging. In the automated bagging task, this method requires a single repeated bag-taking operation, and the process is relatively complicated. The roller-type feeding mechanism can continuously supply paper bags, which is more conducive to the realization of automated bagging operations. On roller-type fruit bagging equipment, the quick and easy replacement of rollers directly determines the efficiency of automated bagging operations. A reasonable roller replacement mechanism can significantly reduce the time for replacing new materials and reduce the size of the roller replacement mechanism, which is an important component for realizing the automated operation of roller-type fruit bagging.

[0033] In the field of roller quick replacement technology, the design of roller quick replacement mechanism is usually used in industrial automation equipment, production line equipment, printing machines, conveyor belt systems and other equipment that require frequent roller replacement. Its main purpose is to improve equipment maintenance efficiency, reduce downtime, and enhance production line flexibility and operational safety. In the roller feeding equipment for fruit bagging operations, paper bag rollers need to be replaced frequently. In the process of automatic fruit bagging, paper bag rollers are consumable materials. Not only do they require the rapid replacement of new paper bag rollers, but they also require the clever return of the used old paper bag rollers.

[0034] The present invention aims to meet the requirement that the paper bag roller in the roller-type fruit bagging equipment needs to be frequently replaced with new materials and the old materials can be discharged at the same time. As a part of the feeding mechanism, the roller replacement mechanism is not only required to be comprehensive in function, easy to use, stable and efficient, and to reduce the power source as much as possible, but also requires the roller replacement mechanism itself to be compact in structure and not occupy too much installation space.

[0035] The present invention provides a roller quick replacement device for roller-type fruit bagging equipment; the rotary replacement mechanism of the present invention can rotate clockwise or counterclockwise, and by using a reasonable structural arrangement, the material of the new roller can be replaced while the material of the old roller can be returned, and the replacement and unloading actions are integrated into one action cycle. The present invention uses a rotary block reset spring, and the spring is compressed or rebounded to realize the automatic counterclockwise rotation of the rotary replacement mechanism, which is simple and reliable. The present invention sets an upper limit stopper and a lower limit stopper to limit the rotation range of the rotary replacement mechanism so that it will not rotate beyond the range, thereby ensuring the reliability of the roller replacement process. The roller replacement of the present invention does not require a power source, and the rapid replacement of the roller can be completed without disassembling the installation components. The integrated design of the roller replacement of the present invention significantly improves the working efficiency of equipment that needs to frequently replace the roller material. As an independent module, the device of the present invention can be conveniently embedded in various roller-type feeding mechanisms for use after a suitable scaling manufacturing ratio, and has a certain versatility.

[0036] Example 1

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

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

[0039] In this embodiment, the new roller is introduced into the device from the roller entrance 3. As the new roller goes deeper, the rotation replacement mechanism is squeezed to rotate clockwise, thereby causing the new roller to enter the rotation replacement mechanism. At the same time, due to the clockwise rotation, the rotation replacement mechanism releases the fixation of the old roller, allowing it to freely detach. When the new roller enters the rotation replacement mechanism, the rotation replacement mechanism rotates counterclockwise to reset and fix the new roller at the same time.

[0040] The device also includes a rotating block reset spring installation groove 101, a step hole 103 and a rotating block axial center hole 104, which are respectively installed on the rotating block rotation groove 5, and the step hole 103 and the rotating block axial center hole 104 are coaxial.

[0041] The device further comprises a return spring mounting hole 102 and a roller unlocking cam groove 105 , wherein the return spring mounting hole 102 is mounted in the return spring mounting groove 101 of the rotating block, and the roller unlocking cam groove 105 is mounted on the step hole 103 .

[0042] The rotation replacement mechanism includes a rotating block 2, a roller inlet and outlet slot 201 and two locking block mounting shaft holes 202, the roller inlet and outlet slot 201 is installed on the rotating block 2, the locking block mounting shaft holes 202 are respectively installed on the roller inlet and outlet slot 201 and are vertical, and 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 rotation replacement mechanism also includes a lower locking block ejector pin 210, a roller lower locking block 211 and a lower locking mounting shaft 212, wherein the lower locking mounting shaft 212 is installed in the locking block mounting shaft hole 202, the roller lower locking block 211 is connected to the lower locking mounting shaft 212 via a locking block reset torsion spring 208, and the lower locking block ejector pin 210 is installed on the roller lower locking block 211.

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

[0046] The rotation replacement mechanism also includes a limiting boss 205 and a rotating block shaft core 206, wherein 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 axial center hole 104, and the limiting boss 205 is mounted on the side of the rotating block shaft core 206.

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

[0048] The device further comprises an upper limit stopper 6 and a lower limit stopper 7, and the upper limit stopper 6 and the lower limit stopper 7 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 stopper 6, a lower limit stopper 7, and a rotating block reset spring 8. The rotating block 2 is mounted in the rotating block rotation groove 5 on the mounting base plate 1; the upper locking block 207 of the roller shaft is mounted 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 of the roller shaft is mounted in another group of the locking block mounting shaft holes 202 opened on the back of the rotating block, and the lower locking block mounting shaft 212 is arranged parallel to the upper locking block mounting shaft 209 in the same plane.

[0050] The device is a complete roller quick-change module, which is usually installed and used by two roller quick-change modules relative to each other for roller replacement. In the initial state, the trigger eccentric block 204 of the rotating block 2 contacts the upper limit stopper 6 under the elastic force of the rotating block reset spring 8, and the rotating block 2 is in the initial position. The locking block 207 on the roller shaft is pushed up under the action of the locking block reset torsion spring 208, so as to limit the roller shaft in the direction of the roller entrance 3. At the same time, the lower locking block ejector 10 provided on the lower surface of the lower locking block 211 of the roller shaft contacts the upper surface of the step hole 103, overcomes the torsion force of the locking block reset torsion spring 208 and pushes up, so as to limit the roller shaft in the direction of the roller exit 4. In the initial state, the upper locking block 207 of the roller shaft and the lower locking block 211 of the roller shaft are both protruding in the roller inlet and outlet slot 201, thereby limiting the old roller and preventing it from moving.

[0051] When replacing the old roller material with the new one, the new roller is pushed in parallel from the roller inlet 3. When it is pushed to contact 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 and outlet slot 201 is parallel to the roller inlet 3, the roller inlet and outlet slot 201 is connected to the roller inlet 3, and the lower locking block ejector pin 210 gradually turns from the original contact with the upper surface of the step hole 103 to the contact with the roller unlocking cam groove 105.

[0053] Further, when the rotating block 2 rotates until the trigger eccentric block 204 contacts the lower limit stopper 7, the rotation stops. At this time, the new roller shaft enters the roller inlet and outlet slot 201, and the lower locking block ejector pin 210 completely enters the slot hole of the roller unlocking cam slot 105. Under the action of the locking block reset torsion spring 208, the roller shaft lower locking block 211 rotates downward, and the lower surface of the roller shaft lower locking block 211 contacts the upper surface of the step hole 103, completing the unlocking of the working old roller shaft on the roller outlet 4 side, and then losing the limiting effect of the roller shaft lower locking block 211, the old roller loses its constraint, that is, exits from the roller inlet and outlet slot 201, and then exits through the roller outlet 4, and the material withdrawal of the old roller is completed.

[0054] Furthermore, when the new roller is pushed in until it contacts the upper locking block slope 213, under the action of the new roller, the locking block 207 on the roller shaft is subjected to a vertical downward force and begins to rotate. When the upper locking block slope 213 rotates to be parallel to the upper surface of the roller entry and exit 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 detached 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 is coaxial with the rotating block axis 206. At this time, the torque generated by the contact between the new roller shaft and the side of the roller entrance and exit slot 201 disappears, and the rotating block 2 rotates counterclockwise under the elastic force of the rotating block reset spring 8 until the trigger eccentric block 204 contacts the upper limit stopper 6 again. At this time, the rotating block 2 returns to the initial position, and after the locking block 207 on the drum shaft is disengaged from the new roller shaft, under the torsion of the locking block reset torsion spring 208, the locking block 207 on the roller shaft returns to the raised position, and the new roller on the roller inlet 3 side is re-limited.

[0056] Furthermore, when the rotating block 2 gradually rotates to the initial position, the lower locking block pin 210 gradually disengages from the roller unlocking cam groove 105 and re-contacts with the step hole 103. Under the contact thrust of the step hole 103, the roller shaft lower locking block 211 is lifted again to limit the position of the new roller on the roller outlet 4. At this point, the replacement of the new roller and the withdrawal of the old roller are all completed and all parts return to the initial working position to wait for the next roller material replacement operation.

[0057] Since the roller unlocking cam groove 105 and the lower locking block ejector pin 210 need to be used in conjunction with each other, the roller unlocking cam groove 105 must be on the path of the lower locking block ejector pin 210 when it rotates, so that the lower locking block ejector pin 210 can smoothly enter or leave the roller unlocking cam groove 105, thereby realizing the lifting or rebound of the lower locking block 211 of the roller shaft.

[0058] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
