Description

Technical Field

[0001] This utility model belongs to the field of printing equipment technology, and in particular relates to a quick disassembly structure for printing plate rollers. Background Technology

[0002] In the modern printing industry, to meet the market's demands for diversified printed products and short-cycle production, printing equipment requires frequent changes of printing rollers to adapt to different printing tasks. Previously, the complex roller disassembly methods demanded high skill levels from operators, requiring specialized training to operate proficiently. Furthermore, the cumbersome process made it easy to mishandle and damage the rollers or equipment.

[0003] Therefore, we propose a quick disassembly structure for printing plate rollers. Utility Model Content

[0004] To solve the above problems, this utility model proposes a quick disassembly structure for printing plate rollers, characterized in that it includes a shaft frame and a shaft cover, with lower chambers respectively located at the center of both sides of the shaft frame, and an upper chamber located in the middle of the shaft cover.

[0005] In one example, the shaft frame is shaped like a U-shape, with a space reserved in the middle to accommodate the printing plate roller. This space is larger than the volume of the printing plate roller. Rotating shafts are provided at both ends of the printing plate roller, and bearings are fitted on each rotating shaft. A positioning groove is provided directly below each bearing.

[0006] In one example, each lower chamber is semi-circular in shape, and the shape and size of the internal space of each lower chamber can be precisely matched with the shape and size of half of the bearing. Each lower chamber has a protruding positioning block at its lower end, and each positioning block is precisely matched with the positioning groove on the bearing and is completely placed in the corresponding positioning groove.

[0007] In one example, the upper chamber is entirely semi-circular, and the shape and size of the internal space of the upper chamber can be precisely matched with the shape and size of half of the bearing.

[0008] In one example, a pair of pin holes are fixedly installed on both sides of the shaft frame near the lower chamber, and each pair of pin holes is opposite to the other. Each pin hole is located on both sides of the lower chamber, and a long strip through hole groove is provided on both sides of the shaft frame near the other end of the lower chamber.

[0009] In one example, a shaft cover is provided directly above the lower chamber. Each shaft cover has a circular through hole at one end. Each circular through hole is located in the middle of each pair of pin holes on the shaft bracket and is connected by pins.

[0010] In one example, each shaft cover has an open step at the other end. The thickness of each step is less than the thickness of the entire shaft cover. The position of each opening corresponds one-to-one with the elongated through-hole groove on the shaft bracket, and the width of the opening is the same as the width of the elongated through-hole groove.

[0011] In one example, quick-release bolts are installed in the elongated through-hole slots on both sides of the shaft bracket. The maximum diameter of each quick-release bolt is smaller than the width of the elongated through-hole slot. The bottom end of each quick-release bolt is connected to the elongated through-hole slot by a pin, and a nut is installed at the top end of each quick-release bolt.

[0012] In one example, the shaft bracket and shaft cover are connected by quick-release bolts and secured by nuts. The space formed between each lower and upper chamber can precisely accommodate the bearing, with each bearing placed between its corresponding lower and upper chambers.

[0013] The quick-disassembly structure for printing plate rollers proposed in this utility model can bring the following beneficial effects:

[0014] 1. The operation is simple and easy to understand, which reduces the skill requirements for operators and reduces labor costs.

[0015] 2. It facilitates the maintenance of the printing rollers, shortens maintenance time, and improves production efficiency.

[0029] like Figures 1-5 As shown, an embodiment of this utility model proposes a quick-disassembly structure for a printing plate roller, which includes a shaft frame 1 and a shaft cover 2. The shaft frame 1 is generally U-shaped, with a space reserved in the middle to accommodate the printing plate roller 3, and the space is larger than the volume of the printing plate roller 3.

[0030] Rotating shafts are provided at both ends of the printing roller 3, and bearings 7 are fitted on each rotating shaft. A positioning groove is provided directly below the bearings 7. The function of the bearings 7 is to ensure the smoothness of the printing roller 3 during rotation.

[0031] Lower chambers 4 are centrally located on both sides of the shaft bracket 1. Each lower chamber 4 is semi-circular, and the shape and dimensions of the internal space of all lower chambers 4 precisely match the shape and dimensions of half of the bearing 7. A protruding positioning block is provided at the lower end of the interior of each lower chamber 4, which perfectly matches the positioning groove on the bearing 7. A pair of pin holes are fixedly installed on both sides of the shaft bracket 1 near one end of the lower chamber 4. Each pair of pin holes is opposite to the others and positioned on opposite sides of the lower chamber 4. An elongated through-hole groove is provided at the other end of each lower chamber 4.

[0032] A shaft cover 2 is provided directly above each lower chamber 4. Each shaft cover 2 has a circular through hole at one end, which is located in the middle of each pair of pin holes on the shaft bracket 1 and connected by pins. Each shaft cover 2 can rotate freely along the axis of the corresponding pin hole. The other end of each shaft cover 2 has an open step, the thickness of which is less than the thickness of the entire shaft cover 2. The position of the opening corresponds one-to-one with the elongated through hole groove on the shaft bracket 1, and the width of the opening is the same as the width of the elongated through hole groove. Each shaft cover 2 has an upper chamber 5 in the middle. Each upper chamber 5 is semi-circular in shape, and the shape and size of the internal space of all upper chambers 5 can be precisely matched with the shape and size of half of the bearing 7.

[0033] Quick-release bolts 6 are respectively installed in the elongated through-hole grooves on both sides of the shaft bracket 1. The maximum diameter of the quick-release bolts 6 is smaller than the width of the elongated through-hole grooves. The bottom end of the quick-release bolts 6 is connected to the elongated through-hole grooves by pins and can rotate freely along the axis of the pins. Nuts are provided at the upper ends of the quick-release bolts 6. The shaft cover 2 and the shaft bracket 1 are connected by the quick-release bolts 6 and fixed by the nuts.

[0034] When the shaft cover 2 and the shaft frame 1 are joined together and fixed by the quick-release bolts 6, the space formed between the lower chamber 4 and the upper chamber 5 can precisely fit the bearing 7. The printing roller 3 is placed in the middle of the shaft frame 1, and the bearings 7 at both ends are placed between the lower chamber 4 and the upper chamber 5 on both sides, respectively. At this time, the positioning groove on the bearing 7 is engaged with the positioning block in the lower chamber 4, which can play the role of fixing the bearing 7.

[0035] When it is necessary to disassemble the printing plate roller 3, first loosen the quick-release bolts 6 on both sides of the shaft frame 1 and move them out of the opening of the shaft cover 2. Then, fully open the shaft covers 2 on both sides and finally take the printing plate roller 3 out upwards. The disassembly of the printing plate roller 3 is now complete.

[0036] When installing the printing roller 3, first vertically insert the bearings 7 at both ends of the printing roller 3 into the lower chambers 4 on both sides, ensuring that the positioning grooves of all bearings 7 are fully engaged with the positioning blocks in the lower chambers 4. Then, sequentially cover the shaft covers 2 on both sides, and rotate the quick-release bolts 6 on both sides to the openings of the shaft covers 2. Finally, tighten all nuts to complete the installation of the printing roller 3. After installation, the bottom of the printing roller 3 protrudes far beyond all the edges of the shaft frame 1 to ensure that the printing roller 3 can work normally without interference.

[0037] Working principle: The space formed between each corresponding lower chamber 4 and upper chamber 5 perfectly accommodates the corresponding bearing 7. Positioning blocks, located in all lower chambers 4, perfectly fit the positioning grooves at the lower ends of the bearing 7. When the positioning groove is engaged with the positioning block, the bearing 7 is restricted from rotating within the lower chamber 4, ensuring that the bearing 7 does not rotate during the rotation of the rotating shafts on both sides of the printing roller 3. The shaft cover 2 is closed and secured with quick-release bolts 6, restricting any displacement of the bearing 7. During the entire disassembly or installation process, simply loosen or tighten the quick-release bolts 6 and then open the shaft cover 2.

[0038] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0039] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
