Here, left wallboard 2101 and right wallboard 2104 are distinguished from the left wallboard 2001 and right wallboard 2002 in front, and they are embedded in the inner side of left wallboard 2001 and right wallboard 2002. The left wall panel 2101, the front wall panel 2102, the middle wall panel 2103, and the right wall panel 2104 are connected as one by screws and cylindrical pins. The camshaft 2105 is set on the bearings of the left wall panel 2101 and the middle wall panel 2103. When the camshaft sprocket 2108 rotates one circle, the double-sided cam 2106 also works one cycle. The suction nozzle swing arm support shaft 2107 is set on the bearings of the middle wall panel 2103 and the right wall panel 2104. The upper left swing arm 2108 and the upper right swing arm 2109 are connected to the suction nozzle swing arm support shaft 2107 by keys, so the upper left swing arm 2108 and the upper right swing arm 2109 can swing. The cam follower bearing 2110 is fixed on the upper left swing arm 2108, and the roller follows the curved track of the double-sided cam 2106. The small pin 2113 is fixed on the upper left swing arm 2108 and the upper right swing arm 2109, and the front swing arm 2117 of the suction nozzle is set on the small pin 2113, and the front swing arm 2117 of the suction nozzle can swing around the small pin 2113. The air pipe joint 2118, the suction nozzle seat 2119 and the suction nozzle 2120 are set on the front swing arm 2117 of the suction nozzle, so that the suction nozzle 2120 moves with the front swing arm 2117 of the suction nozzle. The rear swing arm 2111 of the suction nozzle is set on the support shaft 2107 of the suction nozzle swing arm, and can swing around the support shaft 2107 of the suction nozzle swing arm. The cam follower bearing 2112 is fixed on the rear swing arm 2111 of the suction nozzle, and the roller follows the curved track of the double-sided cam 2106. One end of the connecting rod 2115 is connected to the rear swing arm 2111 of the suction nozzle through a short pin shaft 2114, and the other end is connected to the front swing arm 2117 of the suction nozzle through a long pin shaft 2116, so that the double-sided cam 21006 drives the suction nozzle 2120 to perform a compound motion.

[0062] like Figure 7As shown, the double-sided cam 2106 rotates one circle, and the trajectory of the compound motion of the suction nozzle 2120 is abcda. The suction nozzle picks up the cover at position a, passes through positions abc, and transfers the cover from position a to position c; at the same time, the first paper transfer pressure wheel assembly 23 and the first paper transfer driving wheel assembly 26 are provided at position C to cooperate with each other to transfer the cover, and the suction nozzle of the suction nozzle cam assembly 21 reaches position c to release the cover, and passes through position cda, and the suction nozzle returns to the initial position a. The advantage of this mechanism is that the lifting process and return process of the suction nozzle are controlled by the cam curve, the response is fast, the operation is stable and efficient, and it conforms to the law of high-speed motion.

[0063] The suction nozzle negative pressure supply component 22 is as follows Figure 8B As shown, it is composed of a shut-off cam 2201, a cam fixing flange 2202, a solenoid valve mounting plate 2203, a two-way solenoid valve 2204, an air pipe joint A2205, a sealing flange 2206, a slider seat 2207, a compression spring A2208, a cover plate 2209, an air distributor 2210, a hand valve 2211, an air pipe joint B2212, a venting slider 2213, a bearing 2214, an air pipe 2215 and other parts. Among them: the shut-off cam 2201 and the cam fixing flange 2202 are arranged on the camshaft 2105. The solenoid valve mounting plate 2203 is fixed to the left wall plate 2101 and the middle wall plate 2103 by screws. The air pipe joint A2205 connects the external negative pressure gas source and the two-way solenoid valve 2204, and the two-way solenoid valve 2204 is fixed to the solenoid valve mounting plate 2203 by screws.

The cover plate 2209 is fixed to the slider seat 2207 by screws. The bearing 2214 is arranged on the ventilation slider 2213. Under the action of the compression spring 2208, the bearing moves closely to the curve track of the air cut-off cam 2201, thereby controlling the on and off of the air source. The air pipe 2215 is connected to the air pipe joint 2212 to supply air to the suction nozzle 2120.

[0064] In this embodiment, the external negative pressure gas source is connected to the air pipe joint A2205, the camshaft sprocket 2208 rotates one circle, and the air cut-off cam 2201 controls the ventilation slider 2213 to switch on and off the negative pressure gas source for one working cycle, and then the suction nozzle 2120 works for one cycle. The advantage of this structure is that the two-way solenoid valve always maintains the ventilation state during normal sealing work, and the negative pressure gas source is switched on and off by the cam, and the mechanical valve structure responds quickly; when the sealing work is not required, the two-way solenoid valve 2204 cuts off the gas source supply, and no mechanism action change is required.

The first paper transfer small shaft 2309 is installed on the first paper transfer pressure block 2308, and the first paper transfer small swing arm 2310 is installed on the first paper transfer small shaft 2309 through the first paper transfer bearing 2311.

Under the spring force of the first paper transfer pressure spring 2313, the first paper transfer wheel support shaft 2304 rotates slightly and is converted into the lifting and pressing action of the first paper transfer pressure wheel 2312. In other words, the mechanism adopts a cam swing arm structure to realize the lifting and pressing action of the first paper transfer pressure wheel 2312.

Among them: the second paper transfer roller cam 2401 is arranged on the cam shaft 2105 through the second paper transfer roller sleeve 2402. The second paper transfer roller support shaft 2405 is arranged on the bearings of the left wall panel 2101 and the right wall panel 2104. The second paper transfer roller cam swing arm 2404 is connected to the second paper transfer roller support shaft 2405 through a flat key. The second paper transfer wheel cam roller 2403 is fixed on the second paper transfer wheel cam swing arm 2404, and the roller acts on the curved track of the cam, thereby causing the second paper transfer wheel cam 2401 to drive the second paper transfer wheel support shaft 2405 to rotate slightly. The second paper transfer wheel pressure block 2406 is clamped to the second paper transfer wheel support shaft 2405 by screws. The second paper transfer pressure wheel 2409 is fixed on the second paper transfer wheel pressure wheel swing arm 2408, and the second paper transfer wheel pressure wheel swing arm 2408 is sleeved on the second paper transfer wheel support shaft 2405. Under the spring force of the second paper transfer wheel pressure spring 2407, the small rotation of the second paper transfer wheel support shaft 2405 is converted into the lifting and pressing action of the second paper transfer pressure wheel 2409. Further, the mechanism adopts a cam swing arm structure to realize the lifting and pressing action of the second paper transfer pressure wheel 2409.

[0068] The cover height detection cam assembly 25 is composed of a height detection cam 2501, a height detection spring support plate 2502, a height detection spring 2503, a height detection proximity switch 2504, a height detection cam roller 2505, a height detection cam swing arm 2506, a height detection high pressure block 2507, a height detection swing rod 2508, a height detection adjustable screw 2509, a height detection swing arm 2510, a height detection swing arm mandrel 2511 and other parts.

The height detection cam 2501 is a double-sided external cam, and the two height detection cam rollers 2505 of the height detection cam swing arm 2506 closely follow the cam curve track. The height detection cam swing arm 2506 is sleeved on the first paper transfer wheel support shaft 2304, so that the height detection high pressure block 2507 on the height detection cam swing arm 2506 can swing slightly.

One end of the height-detecting tension spring 2503 is hung on the height-detecting tension spring support plate 2502, and the other end is hung on the height-detecting swing rod 2508. Therefore, under the spring force of the height-detecting tension spring 2503, the height-detecting high pressure block 2507 on the height-detecting cam swing arm 2506 swings slightly, and the rotation is converted into the lifting and pressing action of the height-detecting adjustable screw 2509. In this embodiment, the lifting and pressing action of the height-detecting adjustable screw 2509 is realized by adopting a cam swing arm structure. When the cover is at a high position, the height-adjustable screw rod 2509 has a short downward distance, the height-adjustable proximity switch 2504 does not receive a signal, and the cover does not need to be moved forward; when the cover is at a low position, the height-adjustable screw rod 2509 has a long downward distance, the height-adjustable proximity switch 2504 receives a signal, and the cover needs to be moved forward, thereby realizing the judgment of the high and low positions of the cover. Each working cycle detects and monitors the high and low positions of the cover, so that the cover can be fed and replenished in time to ensure that the cover picking range is effective.

[0075] In this embodiment, the sealing mechanism is mainly composed of three parts, namely, a cover table 1, a sealing mechanism 2, and a push gauge mechanism 3. It adopts a modular design concept and is easy to operate online. The double-sided cam sealing mechanism of the binder adopts a servo motor and a precision screw sub-mechanism to locate the cover position, and controls the sealing action through a cam rocker mechanism and a cam mechanical valve mechanism, so as to efficiently and stably complete the whole sealing process. The double-sided cam sealing mechanism power system of the binder is linked with the main shaft of the binder, and the synchronization and responsiveness are very good. The function of the cover table is to store a large number of covers, which are arranged neatly and evenly in a fish scale style on the belt, and the covers are moved to the sealing mechanism as needed, and the covers can be loaded at the rear end of the cover table at any time. The function of the sealing mechanism is to vacuum absorb a single cover through a suction nozzle, separate a single cover from the cover pile arranged in fish scales on the cover table, and transmit the cover to the push gauge mechanism according to the machine beat. The function of the push gauge mechanism is to transmit a single cover to the binder at equal intervals to ensure that a book core is supplied with a cover. The double-sided cam sealing mechanism of the perfect binder adopts multiple mechanical cam mechanisms in linkage, which conforms to the law of high-speed movement. The mechanism can separate single covers reliably and transmit single covers at high speed and stability. This structure breaks through the technical solution of the existing sealing mechanism, and the implementation scheme is very suitable for high-speed binding linkage lines.
