[0044] The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments, not all embodiments.

[0045] Example

[0046] like Figures 1 to 5 As shown, this embodiment provides a quick-release structure, including: a rubber roller body 10, a transmission seat assembly 20, and a quick-release connecting seat 30.

[0047] Specifically, the rubber roller body 10 includes a roller core 11 and a rubber sleeve 12; the roller core 11 and the rubber sleeve 12 are detachably connected.

[0048] Since the roller core 11 and the rubber sleeve 12 are detachably connected, there is no need to prepare multiple sets of integrated roller core, rubber sleeve and rubber roller. Only one roller core is needed, which can be used with multiple rubber sleeves to adapt to various production processes, thus reducing the manufacturing cost.

[0049] Specifically, the drive seat assembly 20 is configured to connect to one side of the roller core 11. The quick-release connector 30 is configured to connect to the other side of the roller core 11.

[0050] In this embodiment, the quick-release connector 30 includes a movable seat 31, a fixed seat 32, a guide sliding assembly 33, and a locking assembly 34.

[0051] Furthermore, a first bearing 311 is provided on the movable seat 31, and the roller core 11 is rotatably connected to the movable seat 31 via the first bearing 311, and the roller core 11 can be pulled out from the first bearing 311. The movable seat 31 is configured to be slidably connected to the fixed seat 32 via the guide sliding assembly 33, and the sliding axis of the movable seat 31 is parallel to the central axis of the roller core 11.

[0052] Furthermore, the locking component 34 is used to lock the movable seat 31 onto the fixed seat 32.

[0053] When replacing the rubber sleeve 12, after releasing the locking effect of the locking component 34, the movable seat 31 can be pulled out, providing operating space for replacing the rubber sleeve 12. Compared with the existing dot-coating roller structure, it is lower in cost and easier and faster to operate.

[0054] In this embodiment, the roller core 11 has an air chamber 111, an air inlet channel 112, and a plurality of air outlet holes 113.

[0055] Specifically, both the air intake channel 112 and the air outlet 113 are connected to the air chamber 111. The air outlet 113 is located in the area covered by the rubber sleeve 12. The air intake of the air intake channel 112 is located in the area not covered by the rubber sleeve 12.

[0056] Furthermore, the multiple air vents 113 are arranged in a ring array.

[0057] By adding a ventilation structure to the roller core, air can be injected into the air chamber 111 when the rubber sleeve 12 is disassembled, causing separation between the roller core and the rubber sleeve, making the rubber sleeve easier to remove and effectively improving the disassembly speed of the rubber sleeve.

[0058] In this embodiment, two locking components 34 are provided, and the two locking components 34 are distributed on both sides of the fixing base 32. The locking component 34 includes a connecting plate 341 and a bolt 342.

[0059] Specifically, the connecting plate 341 is fixedly connected to the fixed seat 32. The movable seat 31 is provided with a screw hole (not shown) that matches the bolt 342. The connecting plate 341 is provided with a through hole (not shown). The bolt stalk of the bolt 342 passes through the through hole and is screwed into the screw hole.

[0060] Furthermore, to improve ease of disassembly and assembly, bolt 342 is a butterfly-shaped hand-tightening bolt.

[0061] In this embodiment, the transmission assembly 20 includes a geared motor 21 and a bearing housing 22.

[0062] Specifically, the bearing housing 22 has a second bearing 221, and the roller core 11 is rotatably connected to the bearing housing 22 through the second bearing 221.

[0063] Specifically, the output shaft of the geared motor 21 is connected to the roller core 11 via a coupling 23. A connecting frame 24 is provided between the geared motor 21 and the bearing housing 22. Both the geared motor 21 and the bearing housing 22 are fixedly connected to the connecting frame 24. The coupling is located inside the connecting frame 24.

[0064] In this embodiment, the guide sliding assembly 33 includes a guide rod 331 and a third bearing 332.

[0065] Specifically, the guide rod 331 is fixedly mounted on the fixed seat 32 at its head end, and the movable seat 31 is provided with an assembly hole (not shown), and the third bearing 332 is fixedly mounted in the assembly hole.

[0066] Furthermore, the central axis of the guide rod 331 is parallel to the central axis of the roller core; the central axis of the first bearing 311 coincides with the central axis of the second bearing 221.

[0067] Furthermore, the guide rod 331 is provided with two rods: one of which is slightly longer than the thickness of the linear bearing; the other is significantly longer than the thickness of the linear bearing, and its end is fixed to a limiting plate 333 to limit the axial displacement of the movable seat 31 and prevent it from detaching from the guide rod.

[0068] When replacing the rubber sleeve 12, the movable seat 31 slides off along the short guide rod and can then rotate around the axis of the long guide rod to avoid the rubber sleeve. This design eliminates the need for manual support of the movable seat 31, allowing it to remain suspended autonomously during operation, significantly improving the ease of replacement and reducing labor costs.

[0069] For example, the ratio of the length of the short guide rod to the thickness of the linear bearing is 62:42; the ratio of the length of the long guide rod to the thickness of the linear bearing is 127:42.

[0070] In this embodiment, both the movable seat 31 and the fixed seat 32 are L-shaped.

[0071] In some embodiments not shown, the quick-release structure also includes an air supply device for supplying air to the air chamber through an air intake channel.

[0072] Furthermore, the air supply equipment uses an air pump, and the exhaust port of the air pump is connected to an air pipe. To improve the ease of connection, both the air pipe and the roller core are equipped with quick connectors, which allow for quick connection and disconnection. The quick connector on the roller core is connected to the air inlet channel.

[0073] like Figure 6 As shown, in some embodiments, the locking component 34 is a latch lock, which includes a latch body 343 and a lock body 344.

[0074] The buckle 343 is fixedly mounted on the movable seat 31, and the lock body 344 is fixedly mounted on the fixed seat 32.

[0075] like Figure 7 As shown, in some embodiments, three locking components 34 are used, which are distributed on three different surfaces.

[0076] Furthermore, one of the locking components is a latch lock, with its latch body 343 fixedly disposed on the front of the movable seat 31 and its lock body 344 fixedly disposed on the front of the fixed seat 32.

[0077] The other two locking components are located on both sides of the fixed base 32, and each of the two locking components includes a connecting plate 341 and a bolt 342. The connecting plate 341 is fixedly connected to the fixed base 32. The movable base 31 is provided with a screw hole that matches the bolt 342. The connecting plate 341 is provided with a through hole. The bolt 342 passes through the through hole and is screwed into the screw hole. The bolt 342 is a hand-tightening bolt.

[0078] Locking component 34 can be locked and unlocked without the need for any additional tools, and can be done by hand, making it very convenient.

[0079] In addition, this utility model also provides a separator coating machine, including the quick-release structure in any of the above embodiments.

[0080] Although embodiments of this application have been shown and described above, the scope of protection of this utility model is not limited thereto. Any changes or substitutions that can be conceived without inventive effort should be included within the scope of protection of this utility model. Unless expressly stated otherwise, no element, action or instruction used herein should be construed as critical or necessary.
