Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

Fig. 1 to 4 show an ink-saving screen printing machine according to an embodiment of the present invention, which includes a screen frame 1 and an ink returning plate 2. The ink return plate 2 is located in the screen frame 1. The inner side surface of the screen frame 1 is connected with an ink resetting mechanism 3, and the ink returning plate 2 is connected with a one-way trigger mechanism 4 for triggering the ink resetting mechanism 3 in a one-way mode. The one-way trigger mechanism 4 triggers the ink resetting mechanism 3 to push the ink on the outer sides of the two ends of the ink returning plate 2 back to the passing path of the ink returning plate 2.

When the detailed working process of this embodiment is for utilizing ink return plate 2 to scrape ink back, one-way trigger mechanism 4 triggers ink canceling release mechanical system 3 and pushes away ink to ink return plate 2's the ink path of scraping, treats printing back next time, retrieves when ink return plate 2 scrapes back again to reach the effect that will follow the ink recovery that the scraper blade both sides were slided away.

In addition, a plurality of ink resetting mechanisms 3 are arranged, and the ink resetting mechanisms 3 which are respectively positioned at two sides of the ink returning plate 2 and are arranged at the same side are sequentially and uniformly arranged. In order to improve the recovery effect of the ink, two opposite sides of the inner frame of the screen frame 1 are connected with a plurality of ink resetting mechanisms 3, and the one-way triggering mechanisms 4 sequentially trigger the ink resetting mechanisms 3 which are in contact with each other to recover the ink.

Specifically, the ink resetting mechanism 3 includes a support long block 31, a transmission member 32, a switching member 33, and an output member 34. The support long blocks 31 are arranged in two and distributed in parallel up and down. One end of each of the two support long blocks 31 is fixedly connected with the net frame 1. The two support long blocks 31 are respectively provided with vertical through holes 312 penetrating in the vertical direction. The transmission member 32 includes a transmission rod 321 and a transmission rotation shaft 322. The transmission shaft 322 is connected to the two vertical through holes 312 through two bearings. One end of the transmission rod 321 is vertically connected with one end of the transmission rotating shaft 322, and the other end of the transmission rod 321 is used for contacting with the one-way trigger mechanism 4. The transmission shaft 322 is fixedly connected with the conversion member 33 positioned between the two support long blocks, and the conversion member 33 is connected with the output member 34. The conversion member 33 converts the motion transmitted from the transmission member 32 into a reciprocating motion and then drives the output member 34 to scrape the ink.

The detailed working process of this embodiment is that after the one-way trigger mechanism 4 touches the transmission rod 321, the transmission rotating shaft 322 is driven to rotate, so as to convert the linear reciprocating motion of the one-way trigger mechanism 4 into the rotation of the transmission rotating shaft 322, so as to drive the converting member 33.

Further, the conversion member 33 includes a conversion driving gear 331, a conversion driven gear 332, a first slide lever 333, and a maintaining unit 334. The conversion driving gear 331 is eccentrically and fixedly connected with the transmission rotating shaft 322 and has an axis parallel to the transmission rotating shaft. The two support long blocks 31 are both provided with sliding grooves 311 along the length direction. Both ends of the first sliding rod 333 are slidably engaged with the sliding grooves 311 along the length direction of the sliding grooves 311. The first slide rod 333 is connected to the switching driven gear 332 through a bearing. The switching driven gear 332 is engaged with the switching driving gear 331. Both ends of the maintaining unit 334 are connected to the driving rotation shaft 322 and the first sliding rod 333, respectively. The maintaining unit 334 serves to maintain the conversion driving gear 331 and the conversion driven gear 332 in an engaged state. The transition follower gear 332 is connected with the output member 34.

The detailed working process of this embodiment is that the rotation of the transmission rotation shaft 322 drives the conversion driving gear 331 to perform eccentric rotation, and the conversion driven gear 332 engaged with the conversion driving gear 331 drives the first sliding rod 333 to slide along the length direction of the sliding slot 311 in the forced rotation process, so as to realize the reciprocating linear motion of the output member 34 connected with the sliding rod. Namely the pushing of the ink and the retraction of the device.

Also, two holding units 334 are provided. The two retaining units 334 are respectively located at the upper and lower sides of the switching driving gear 331. The maintaining unit 334 includes a driving tube 334a, a driven tube 334b, and a tension spring 334 c. One ends of the driving tube 334a and the driven tube 334b are closed. The other end of the driven tube 334b is slidably inserted into the other end of the active tube 334 a. A tension spring 334c is located within the driven tube 334 b. One end of the tension spring 334c is connected to the closed end of the driven tube 334b, and the other end of the tension spring 334c is connected to the closed end of the driving tube 334 a. The closed ends of the driving tube 334a and the driven tube 334b are both provided with through holes which vertically penetrate. The transmission rotation shaft 322 is connected to the through hole of the driving pipe 334a through a bearing, and the first sliding rod 333 is connected to the through hole of the driven pipe 334b through a bearing.

The detailed working process of this embodiment is that when the switching driving gear 331 rotates eccentrically in a small range, first, the driven tube 334b is gradually drawn out from the driving tube 334a, and the tension spring 334c is lengthened; when the switching driving gear rotates reversely, the driven tube 334b is inserted into the driving tube 334a, the tension spring 334c contracts, and the switching driven gear 332 is pulled back, ensuring the engagement of the switching driving gear 331 and the switching driven gear 332.

Further, the output member 34 includes a second sliding rod 341, an output gear 342, an output rod 343, a connecting rod 344, and a push plate 345. The two ends of the second sliding rod 341 are in sliding fit with the sliding groove 311 along the length direction of the sliding groove 311. One end of the connecting rod 344 is coaxially connected to the closed end of the driven tube 334b along the axial center line, and the other end of the connecting rod 344 is opened with a through hole penetrating along the radial direction thereof. The second sliding rod 341 is interference-fitted with the through hole of the connection rod 344. The output gear 342 is screwed with the second sliding rod 341 coaxially with the axial center line. The output gear 342 meshes with the switching driven gear 332. An end of the output gear 342 remote from the switching driven gear 332 is connected to a push plate 345 outside the support long block 31 via an output rod 343.

The detailed working process of this embodiment is that the connecting rod 344 supports the second sliding rod 341, when the switching driven gear 332 rotates, the output gear 342 engaged with the switching driven gear rotates, and since the output gear 342 is in threaded connection with the second sliding rod 341, the second sliding rod 341 is in interference fit with the through hole of the connecting rod 344. The second sliding shaft 341 does not rotate with respect to the connection shaft 344. When the output gear 342 is driven by the switching driven gear 332 to rotate, the output gear can also move up and down relative to the second sliding rod 341, so that the push plate 345 connected with the output rod 343 slowly descends to contact with the grids in the screen frame 1 when being pushed out and then pushes ink, and when the push plate 345 returns, the push plate can be upwards retracted, the ink cannot be continuously scraped on the grids, and the defects of multiple residual ink positions are reduced.

To increase the stability of the apparatus, the first slide bar 333 is connected at both ends thereof with anti-tilting blocks 335. The surfaces of the two anti-tilt blocks 335 facing away from the first slide bar 333 are in contact with the bottom surfaces of the corresponding slide grooves 311, respectively. The abutment of the anti-tilt block 335 against the bottom of the slide slot 311 reduces the risk of the first slide bar 333 tilting.

Further, the one-way trigger mechanism 4 includes a trigger lever 41 and a support lever 42. The support rod 42 is fixedly connected with the ink return plate 2. The middle of the trigger lever 41 is connected to the support lever 42. Both ends of the trigger rod 41 are provided with a placing hole 411 which is coaxial with the axial center line. The orifice of each seating hole 411 is provided with an inwardly constricted blocking ring 43. Each of the seating holes 411 is provided therein with a set of triggering members 44.

The trigger member 44 includes a trigger block 441 and a trigger spring 442. One end of the trigger block 441 is inserted into the stop ring 43 and then sleeved with a limiting pipe with the same center line, and the other end of the trigger block 441 is connected with a wedge block 443. The inclined surfaces of the wedge blocks 443 contact the corresponding drive rod 321. The outer wall of the limiting pipe is in clearance fit with the placing hole 411. The trigger spring 442 is located in the seating hole 411. One end of the trigger spring 442 abuts against one end of the trigger block 441 far away from the wedge-shaped block 443, and the other end of the trigger spring 442 abuts against the bottom of the seating hole 411.

The detailed operation of this embodiment is that when the transmission rod 321 moves in the forward direction to abut against the inclined surface of the wedge 443, the trigger block 441 is forced to retract to give way. When the transmission rod 321 moves in the opposite direction to abut against the wedge-shaped block 443, the trigger block 441 cannot be recovered, and the transmission rod 321 drives the transmission rotating shaft 322 to rotate, thereby completing the power transmission process.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
