[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.
[0029] A fixture for printing on the surface of a glass cup, used for clamping a glass cup in the shape of a rotating body with an opening, comprising: The clamping pipe assembly 1 includes a clamping main pipe 11 and a connecting end pipe 12 connected to the right side of the clamping main pipe 11; A Bernoulli suction cup 2 is provided at the left end of the clamping main pipe 11; the Bernoulli suction cup 2 includes a guide conical groove 21 that gradually concave from the outside to the inside and toward the right, and positive pressure holes 22 that are evenly distributed circumferentially on the inner wall of the left end of the clamping main pipe 11 and communicate with the guide conical groove 21; The radial support device 3 is provided on the outer wall of the clamping main pipe 11 to support the inner wall of the opening side of the glass.

The inner wall of each guide sleeve 92 is also provided with a radial plug 93; The follower rotating assembly 8 includes a follower ring 81 rotatably provided in the left half of the annular right cavity 131, a limiting ring groove 82 provided on the right end surface of the follower ring 81 and accommodating the stop convex ring 133, inclined slots 83 uniformly distributed circumferentially on the outer wall of the follower ring 81 and plugged into the radial plugs 93, a small-diameter circular tube 84 provided on the left side of the follower ring 81 and inserted into the small-diameter circular cavity 135, and a rotating disk 85 provided on the outer wall of the small-diameter circular tube 84 and rotatably engaged with the rotating circular cavity 136. Each rotating disk 85 is also uniformly distributed circumferentially with inclined through holes 86 corresponding to the radial channels 137. The radial expansion assembly 7 corresponds to the radial channel 137 in a one-to-one manner. The radial expansion assembly 7 includes a radial slider 71 slidably disposed in the radial channel 137, an accommodating opening 72 disposed on the radial slider 71 and accommodating the rotating disk 85, and an opening cross bar 73 disposed in the accommodating opening 72 and pluggably engaged with the inclined through hole 86. The return compression spring 6 corresponds to the guide core rod 134 one by one. The return compression spring 6 is wound around the corresponding guide core rod 134 and abuts against the left side of the guide sleeve 92.
[0032] The resistance adjustment device 5 includes a resistance adjustment chamber 51 and a resistance adjustment component 52; The resistance-adjusting chamber 51 includes a resistance-adjusting ring groove 511 provided on the outer wall of the clamping main pipe 31, and also includes axial sockets 512 uniformly distributed circumferentially on the outer wall of the clamping main pipe 31 and corresponding one-to-one with the guide core rod 134. The axial sockets 512 extend rightward to the left half of the corresponding guide core rod 134. The guide core rod 134 is also uniformly distributed with anti-rotation side holes 513 at the corresponding positions of the axial sockets 512. Each axial socket 512 is also provided with a gear groove 514 connected to the resistance-adjusting ring groove 511; the resistance-adjusting ring groove 511 is located between the annular right chamber 131 and the radial channel 137; The resistance adjustment assembly 52 includes a ring gear 521 rotatably arranged in the resistance adjustment ring groove 511, and also includes a driven small tooth 522 arranged in the corresponding gear groove 514 and meshing with the ring gear 521, an internal threaded hole 523 arranged at the center axis of the driven small tooth 522, an external threaded rod 524 slidably arranged in the axial socket 512 and screwed to the internal threaded hole 523, a stop-rotation connecting rod 525 circumferentially distributed on the right end of the external threaded rod 524 and passing through the stop-rotation side hole 513, and a resistance adjustment slip ring 526 slidably arranged on the guide core rod 134 at the left side of the reset compression spring 6, and the inner wall of the resistance adjustment slip ring 526 is fixedly connected to the stop-rotation connecting rod 525.
[0033] This case also discloses a printer using the aforementioned clamp, which includes at least a loading assembly 10 for realizing continuous loading of glass cups. The loading assembly 10 includes an intermittent rotating device 101 for driving three clamps to rotate cyclically, a conveyor line device 102 for transporting glass cups, a pushing device 103 for pushing glass cups into the clamp located at the lower front, and a retrieval device 104 for removing glass cups from the clamp located at the lower rear.
[0034] Thanks to this improved technical solution, while a glass on the upper fixture is being printed, the already printed glass on the lower, rear fixture is simultaneously removed, while the unprinted glass on the lower, front fixture is simultaneously pushed in. The intermittent rotation device 101 rotates a single angle to cycle through the process. By employing three fixtures and implementing intermittent rotation, the printer in this case synchronizes the glass installation and removal steps with the printing process, significantly improving loading efficiency.
[0035] The glasses described in this case are mostly open glasses with a flat bottom and a twisted body, and any cross-section perpendicular to their central axis is circular. The fixture described in this case can accommodate glasses with different outer wall shapes and provides dual fixation of the flat bottom and the circular sidewalls of the glass: S1, cup bottom fixed: The glass is pushed into the fixture by the pushing device 103 with its opening facing right; The airflow provided by the first positive pressure air source passes through the connecting end tube 12 and the clamping main tube 11 and enters the Bernoulli suction cup 2. The airflow is guided to blow out quickly toward the periphery through the positive pressure holes 22 of the Bernoulli suction cup 2, thereby reducing the air pressure at the left end of the Bernoulli suction cup 2 and adsorbing the flat cup bottom.
[0036] S2, cup wall fixed: The first positive pressure air source simultaneously enters the right end of the annular right cavity 131 through the air inlet hole 132; The first positive pressure air source squeezes the positive pressure sliding assembly 9 to make it move to the left, overcoming the damping of the return compression spring 6. During the movement, the sliding assembly 9 is limited in its rotational freedom by the insertion and cooperation between the guide sleeve 92 and the guide core rod 134, so that it can only slide in translation but not rotate. The radial plug 93 acts on the inclined slot 83, thereby driving the follower rotating assembly 8 to rotate; The inclined through hole 86 rotates and acts on the open cross bar 73, driving the radial telescopic assembly 7 to extend outward until the radial slider 71 abuts against the circumferential inner wall of the glass.
[0037] Furthermore, the resistance adjustment device 5 can adjust the damping of the return compression spring 6: The ring gear 521 is rotated, and the ring gear 521 drives the driven small tooth 522 and the internal threaded hole 523 to rotate, and the internal threaded hole 523 drives the external threaded rod 524, the anti-rotation connecting rod 525, and the resistance adjustment sliding ring 526 to move, thereby adjusting the compression amount and elastic force of the return compression spring 6 under normal conditions.
[0038] It should be noted that the radial support device 3 of the clamp described in this case also includes a sealing assembly 4 for achieving sealing between the sealing ring body 91 and the annular right cavity 131. The sealing assembly 4 includes a sealing base 41, a sealing outer ring 42, a sealing inner ring 43, and an actuating component 44. The sealing base 41 includes an outer ring groove 411 provided on the right side of the outer edge of the sealing ring body 91, an inner ring groove 412 provided on the right side of the inner edge of the sealing ring body 91, an annular inner cavity 413 formed inside the sealing ring body 91, and radial through holes 414 uniformly distributed on the sealing ring body 91 and connected to the annular inner cavity 413. The sealing outer ring 42 is sleeved on the left side of the outer ring groove 411; The sealing inner ring 43 is sleeved on the left side of the inner ring groove 412; The action component 44 includes an action outer ring 441 slidably arranged on the outer ring groove 411 and an action inner ring 442 arranged on the inner ring groove 412. The inner wall of the action outer ring 441 is also circumferentially evenly distributed with a driven connecting rod 443 arranged through the corresponding radial through hole 414. The inner side of the driven connecting rod 443 is fixedly connected to the action inner ring 442. The action component 44 also includes a rotatable annular worm gear 444 arranged on the right side of the annular inner cavity 413. The left side of the annular worm gear 444 is circumferentially evenly distributed with an arc-shaped pressure plate 445 which gradually rises in a clockwise direction. The arc-shaped pressure plate 445 is in one-to-one contact with the driven connecting rod 443. The sealing ring body 91 is also provided with a worm socket connected to the annular inner cavity 413 and a driving worm 446 is rotatably provided in the worm socket. The driving worm 446 is meshed with the annular worm gear 444.
[0039] Thanks to the above-mentioned improved technical solution, the sealing degree between the annular right cavity 131 and the sealing ring body 91 can be adjusted: The active worm 446 is rotated to drive the annular worm gear 444 and the arc-shaped pressure plate 445 to rotate. The arc-shaped pressure plate 445 squeezes the corresponding driven connecting rod 443 to drive the outer ring 441 and the inner ring 442 to move. The actuating outer ring 441 squeezes the sealing outer ring 42 to deform it radially, thereby adjusting the sealing degree between the outer wall of the sealing ring body 91 and the outer wall of the annular right cavity 131; The action inner ring 442 squeezes the sealing inner ring 43 to deform it radially, thereby adjusting the sealing degree between the inner wall of the sealing ring body 91 and the inner wall of the annular right cavity 131 .
[0040] It should be noted that the rotating annular cavity 136 and the rotating disc 85 are each provided in pair.
[0041] It should be noted that the clamps of the aforementioned embodiments further include a positive-pressure core tube at the center of the clamping tube assembly 1, independently connected to a second positive-pressure air source. The left side of this positive-pressure core tube extends through the Bernoulli suction cup 2. To remove a glass from the clamp, the first positive-pressure air source is deactivated, freeing the clamp from securing the glass. The second positive-pressure air source is then activated, generating positive-pressure gas at the left end of the positive-pressure core tube, causing the glass to move leftward from the clamp, allowing the retrieval device 104 to remove the glass.
