Description

Technical Field

[0001] This utility model relates to the field of screen cylinder technology, specifically to a split-type cleaning machine screen cylinder. Background Technology

[0002] During the operation of the cleaning machine, the screen cylinder is a key component, and its performance directly affects the cleaning effect and efficiency. Traditional cleaning machine screen cylinders are mostly one-piece structures. This structure is complex to manufacture and has a high cost. Moreover, once a screen plate is damaged, the entire screen cylinder needs to be replaced, which not only wastes resources but also increases maintenance costs and time.

[0003] The existing patent application with publication number CN222642495U describes a method where the mounting plate at the end of the damaged screen plate can be removed from the outer wall of the connecting plate by unscrewing the fixing bolts at the corresponding positions. After the connecting plate is removed, the limiting pin on its inner side will disengage from the limiting hole. Then, the mounting plate at the other end of the screen plate can be disassembled in the same way. After both mounting plates at both ends are disassembled, the damaged part of the screen plate can be disassembled separately. However, this method requires unscrewing multiple bolts, which affects the disassembly efficiency of the damaged screen plate. Therefore, we propose a split-type screen cylinder for a cleaning machine. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] See attached document Figure 1-5 A split-type cleaning machine screen cylinder includes an annular bottom ring 1. Several equidistant positioning frames 2 are installed circumferentially on the bottom ring 1. Screen plates 3 are inserted between adjacent positioning frames 2. The screen plates 3 are detachably connected to the positioning frames 2. Slide plates 31 are symmetrically provided on both sides of the screen plates 3. Slide grooves 21 are symmetrically opened on both sides of the positioning frames 2 along their length direction for inserting the slide plates 31, so as to realize the plug-in connection between the screen plates 3 and the adjacent positioning frames 2. When installing the screen plates 3, the slide plates 31 are aligned with the slide grooves 21 and inserted to realize the quick installation of the screen plates 3 and the adjacent positioning frames 2. When a screen plate 3 is damaged and needs to be replaced, the damaged screen plate 3 only needs to be pulled upward to separate the screen plate 3 from the positioning frame 2. The installation and disassembly process is simple, convenient and efficient.

[0028] In this embodiment, the top of the positioning frame 2 is provided with a slot, and a buckle is engaged in the slot. The two sides of the buckle abut against the top of the side of the adjacent screen plate 3 to limit the top of the screen plate 3, prevent the screen plate 3 from being displaced due to vibration during operation, and ensure that the cleaning machine screen cylinder can work accurately and stably.

[0029] In this embodiment, the snap-fit ​​part includes a blocking block 41. The bottom of the blocking block 41 is symmetrically provided with two snap feet 42. There is an interval between the two snap feet 42, which can not only ensure the guiding effect during insertion, but also accommodate the deformation of the two snap feet 42. The two snap feet 42 extend outward from the opposite side. The slot part includes a receiving groove 221 opened on the top of the positioning frame 2 to receive the blocking block 41. The receiving groove 221 has a slot 222 for the two snap feet 42 to be inserted. The positioning frame 2 has a through groove 223 along its width direction to pass through the slot 222 for the insertion of the outer edge 43. When installing the snap-fit ​​part, the snap feet 42 are aligned with the slot 222 and inserted, and at the same time the outer edge 43 is inserted into the through groove 223, so that the snap-fit ​​part is firmly snapped into the slot. The two mating parts are easy to install and can effectively prevent the snap-fit ​​part from loosening and falling off during operation, ensuring the stability of the screen plate 3.

[0030] In this embodiment, the top of the outer edge 43 on the side away from the latch 42 has an inclined surface. When it is necessary to remove the latch, press the outer edges 43 on both sides to deform and tilt the latches 42 on both sides towards the middle. The inclined surface design makes it easy to remove the latch from the slot.

[0031] In this embodiment, the top of the positioning frame 2 is symmetrically provided with pull slots 224 that connect to the receiving groove 221. The top opening of the pull slot 224 allows for the insertion of fingers. When disassembling the buckle, first press the outer edges 43 on both sides, and then insert two fingers into the pull slot 224. This makes it easy to use your fingers and eliminates the need for a tool ratchet to pull the buckle out of the slot. The operation is simple and convenient.

[0032] In this embodiment, the top of the side of the slide plate 31 that is inserted into the slide groove 21 is provided with a notch 32. The top of the notch 32 is flush with the bottom of the receiving groove 221 so as to realize the contact of the sealing block 41 with the top of the screen plate 3, which helps to improve the fixing ability of the buckle part to the screen plate 3.

[0033] In this embodiment, the top of the sieve plate 3 extends to both sides with an upper edge 33. The design of the upper edge 33 enhances the structural strength of the sieve plate 3 and prevents the sieve plate 3 from deforming during use. On the other hand, it also makes it easy to separate the sieve plate 3 from the positioning frame 2 by pulling the upper edge 33.

[0034] In this embodiment, several positioning frames 2 are fitted together with several outer positioning hoops 5 arranged along their length direction. The outer positioning hoops 5 have a circular structure and their inner walls are in close contact with the outer walls of the screen plate 3. The outer positioning hoops 5 further fix and position the entire screen cylinder, which can not only prevent the screen plate 3 from deforming when the screen cylinder is working, but also enhance the overall structural strength of the screen cylinder and improve the service life of the screen cylinder.
