Description

Technical Field

[0001] This utility model relates to the field of papermaking machine technology, and in particular to an automatic paper feeding device for a papermaking machine. Background Technology

[0002] A paper machine is a complete set of pulp forming equipment that integrates the headbox, wire section, press section, dryer, calender, winding machine, main drive section, and auxiliary systems such as steam, water, vacuum, lubrication, and heat recovery. A paper feeding device is required to feed the paper when using a paper machine.

[0003] A search revealed that Chinese Patent Publication No. CN220617167U discloses an automatic paper feeding device for a papermaking machine, which effectively solves the problem of poor dust prevention in ordinary paper feeding devices by means of a base, a chute, a slider, a dustproof plate, and a dustproof net.

[0004] However, the above technical solution has the following drawbacks when used:

[0005] The dustproof plate is placed directly on the main body of the paper feeding device through the cooperation of the slider and the groove. The lack of a locking structure for the dustproof plate makes it easy for it to fall off the main body of the paper feeding device due to accidental contact by the operator during use, resulting in low efficiency.

[0006] The dustproof nets are symmetrically installed on the dustproof panel and are directly fixed to the panel. If the dustproof nets are damaged and need to be replaced, the entire dustproof panel must also be replaced. It is not possible to replace just a single dustproof net, resulting in high costs and low practicality. Utility Model Content

[0007] The purpose of this utility model is to solve the problems in the background art by proposing an automatic paper feeding device for a papermaking machine.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An automatic paper feeding device for a papermaking machine includes:

[0010] Main body of the paper feeding device;

[0011] A dustproof plate is detachably installed on the top of the paper feeding device body. Two positioning strips are symmetrically fixedly installed on the bottom of the dustproof plate. Positioning frames are slidably sleeved or separated on the surfaces of the two positioning strips, and the positioning frames are fixedly installed on the top of the paper feeding device body.

[0012] Multiple dustproof nets are detachably installed on top of the dustproof panel;

[0013] The positioning assembly includes a fixed housing fixedly installed on the top of a dustproof plate. A spring is provided inside the fixed housing. Both ends of the spring are connected to positioning blocks, and the positioning blocks are slidably connected between the fixed housing and the dustproof plate and extend to both ends of the fixed housing. A driving block is fixedly installed on the top of each of the two positioning blocks, and the driving block moves through to the top of the fixed housing. Both ends of the positioning blocks are engaged with fixing blocks, and the two fixing blocks are fixedly installed on the top of two positioning frames.

[0014] Preferably, limit rods are fixedly installed on both sides of the section of the two positioning blocks extending outside the fixed shell, and the limit rods are in contact with or separate from the top of the dustproof net.

[0015] Preferably, the top of the dustproof plate is provided with multiple mounting slots, and the mounting slots are matched with the dustproof net, and each mounting slot is provided with a through hole at the bottom.

[0016] Preferably, the top of the fixed shell has two symmetrical sliding holes, and the sliding holes are slidably connected to the drive block.

[0017] Preferably, positioning grooves are provided on opposite sides of both fixing blocks, and the positioning grooves match the positioning blocks.

[0018] Preferably, the dustproof plate has slots on both sides, and the slots match the fixing blocks.

[0019] Compared with existing technologies, the advantages of the automatic paper feeding device for a papermaking machine provided by this utility model are as follows:

[0020] 1. By using the spring to push the two fixed blocks in opposite directions, after the dustproof plate is installed on the main body of the paper feeding device, the two positioning blocks can be respectively locked onto the two fixed blocks, thereby fixing the dustproof plate to the main body of the paper feeding device and improving the stability of the dustproof plate on the main body of the paper feeding device.

[0021] 2. After the dustproof plate is removed, the two limit rods will also completely move away from the top of the dustproof net. The staff can then directly push out the dustproof net that needs to be cleaned or replaced from bottom to top, realizing the replacement of a single dustproof net and improving the practicality of the device.

[0022] In summary, this utility model achieves the effect of fixing the dustproof plate to the paper feeding device body by engaging the two positioning blocks on the dustproof plate with the two fixing blocks on the paper feeding device body, thereby improving the stability of the dustproof plate on the paper feeding device body. At the same time, it also enables the replacement of individual dustproof nets, thus improving the practicality of the device. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figures 1 to 3 An automatic paper feeding device for a papermaking machine, comprising:

[0029] The paper feeding device body 1 is not described in this technical solution. For details, please refer to the prior art CN220617167U.

[0030] The dustproof plate 2 is detachably installed on the top of the paper feeding device body 1. Two positioning strips 3 are symmetrically fixedly installed on the bottom of the dustproof plate 2. The surfaces of the two positioning strips 3 are slidably sleeved or separated from the positioning frames 4, and the positioning frames 4 are fixedly installed on the top of the paper feeding device body 1. By using the two positioning strips 3 to engage with the two positioning frames 4 respectively, the dustproof plate 2 can be initially fixed on the paper feeding device body 1.

[0031] Multiple dustproof nets 5 are detachably installed on the top of the dustproof plate 2. The top of the dustproof plate 2 has multiple mounting slots 6, and the mounting slots 6 match the dustproof nets 5. Each mounting slot 6 has a through hole 7 at the bottom. The mounting slots 6 can restrict the dustproof nets 5 to the dustproof plate 2. After the dustproof plate 2 is removed from the paper feeding device body 1, the individual dustproof nets 5 can be disassembled and installed, thus facilitating the replacement of individual dustproof nets 5.

[0032] The positioning assembly includes a fixed housing 8 fixedly installed on the top of the dustproof plate 2. A spring 9 is provided inside the fixed housing 8. Both ends of the spring 9 are connected to positioning blocks 10. The positioning blocks 10 are slidably connected between the fixed housing 8 and the dustproof plate 2 and extend to both ends of the fixed housing 8. Limiting rods 13 are fixedly installed on both sides of the section of the two positioning blocks 10 extending outside the fixed housing 8. The limiting rods 13 are in contact with or separated from the top of the dustproof net 5. When the dustproof plate 2 is fixed on the paper feeding device body 1, the limiting rods 13 can press each dustproof net 5 into the corresponding mounting groove 6. After the dustproof plate 2 is removed, the limiting rods 13 can move away from the dustproof net 5 so that the dustproof net 5 can be replaced.

[0033] A drive block 11 is fixedly installed on the top of each of the two positioning blocks 10, and the drive block 11 extends through to the top of the fixed shell 8. Two sliding holes 14 are symmetrically opened on the top of the fixed shell 8, and the sliding holes 14 are slidably connected to the drive block 11, which facilitates the sliding of the drive block 11 and also prevents the positioning block 10 from detaching from the fixed shell 8.

[0034] Both ends of the positioning block 10 are engaged with fixing blocks 12, and the two fixing blocks 12 are respectively fixedly installed on the top of the two positioning frames 4. The two fixing blocks 12 are provided with positioning grooves 15 on opposite sides, and the positioning grooves 15 match the positioning blocks 10. When the positioning blocks 10 are engaged with the positioning grooves 15, the dustproof plate 2 can be fixed on the paper feeding device body 1.

[0035] Furthermore, the dustproof plate 2 has slots 16 on both sides, and the slots 16 match the fixing block 12. When installing the dustproof plate 2, the engagement of the slots 16 and the fixing block 12 effectively improves the stability of the dustproof plate 2 installed on the paper feeding device body 1.

[0036] The working principle of this utility model is as follows:

[0037] In use, first push the two drive blocks 11 inward to compress the spring 9, then insert the two positioning strips 3 into the two positioning frames 4 respectively, and then release the two drive blocks 11. Under the elastic force of the spring 9, the two drive blocks 11 move in opposite directions until they are inserted into the positioning slots 15 on the two fixed blocks 12 respectively, so that the dustproof plate 2 can be fixed on the paper feeding device body 1. At this time, the limiting rod 13 contacts the top of the dustproof net 5 and fixes the dustproof net 5 in the mounting slot 6.

[0038] During disassembly, press the two drive blocks 11 inward again to disengage them from the fixing block 12, remove the dustproof plate 2, and then release the two drive blocks 11. The spring 9 will then push them open until they contact the opposite end of the two sliding holes 14. At this time, the limit rod 13 will be completely away from the top of the dustproof net 5, and the staff can directly push out the dustproof net 5 that needs to be cleaned or replaced from bottom to top to achieve disassembly and replacement.

[0039] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
