[0002] A screen printing machine is a machine for printing text and images. It is a general term for machines or equipment used to produce printed materials. A screen printing machine is a more representative printing equipment among stencil printing machines. In addition to silk, the materials used to make the screen can also be nylon wire, copper wire, steel wire or stainless steel wire.

[0003] According to the disclosed screen printing machine that is easy to flush (Announcement No.: CN212171604U), in the above application, the support frame is driven to move back and forth inside the slide by the card block, so that the cleaning brush can brush the screen printing plate, which can quickly and conveniently wash away the residual ink on the screen printing plate. The operation is simple, which increases the quality of the later use of the printing machine and further improves the printing efficiency.

[0004] However, during actual use of the above-mentioned equipment, the screen printing plate is fixed on the table of the printer. Although a shock-absorbing component is provided at the bottom to ensure the stability of the screen printing plate during operation, it also limits the depth of cleaning of the screen printing plate by the bristles of the cleaning plate to a certain extent, thereby reducing the flushing and cleaning efficiency of the screen printing plate. In view of this, we propose a screen printing machine that is easy to flush. Utility Model Content

The outer surface of the rotating shaft of the driving plate is provided with a coil spring, and the lower surface of the screen printing plate is fixedly connected to the connecting block, and the connecting block is fixedly connected to the inner wall of the body with a spring.

[0009] Preferably, the lower surface of the cleaning plate is provided with steel wire bristles, and the cleaning plate is moved laterally in conjunction with the steel wire bristles to clean the ink remaining on the surface of the screen printing plate.

[0010] Preferably, a square groove that matches the outer diameter of the elastic telescopic rod is formed on the lower surface of the connecting rod, and the top end of the elastic telescopic rod is slidably connected to the top inner surface of the square groove, so that the elastic telescopic rod can push the connecting rod in the vertical direction without affecting the lateral sliding of the connecting rod. The guide groove is arranged in a "factory" shape, so that the connecting rod moves laterally and then moves downward under the influence of the convex rod and the guide groove.

[0011] Preferably, a plurality of groups of cylindrical ridges are provided on the side wall of the driving plate, and an arc groove adapted to the cylindrical ridges is opened on the side wall of the shift block, thereby increasing the driving effect of the driving plate on the shift block when performing lateral movement.

[0012] Preferably, a swing assembly is provided inside the threaded sleeve, and the swing assembly includes a contact wheel, the contact wheel is rotatably mounted on the inner wall of the threaded sleeve, the contact wheel is coaxially fixedly mounted with a driving wheel, the driving wheel is connected to a driven wheel through a synchronous belt transmission, a reciprocating screw is passed through and fixedly mounted on the axis of the driven wheel, a threaded slider is threaded on the outer wall of the reciprocating screw, one end of a push rod is hinged on the side wall of the threaded slider, the other end of the push rod is hinged to a T-shaped plate, and a shift rod is fixedly mounted on the side wall of the T-shaped plate.

[0014] Compared with the prior art, the present invention provides a screen printing machine that is easy to flush, which has the following beneficial effects:

[0015] 1. The screen printing machine which is easy to flush is provided with a cleaning component. When the threaded sleeve starts to move, the driving plate drives the shift block slide to slide toward one side of the baffle. After the shift block hits the baffle, it drives the baffle and the connecting rod to slide to the right along the inner wall of the machine body. At this time, due to the guidance and restriction of the convex rod and the guide groove, after the connecting rod and the baffle move to the right for a certain distance, the insert block releases the limit of the connecting block, and then the connecting rod drives the baffle to move downward to under the slide. After that, due to the obstruction of the slide, the connecting rod no longer moves upward. At this time, as the threaded sleeve continues to rotate with the threaded rod, it makes a linear motion along the upper surface of the machine body, thereby driving the cleaning plate to clean the upper surface of the screen printing plate. At the same time, through the influence of the wire brush on the screen printing plate, in combination with the spring and the connecting block, the screen printing plate being cleaned will vibrate slightly up and down to improve the cleaning effect of the wire brush.

[0016] 2. The screen printing machine that is easy to flush is provided with a swinging assembly. The threaded sleeve slides along the upper surface of the machine body and drives the cleaning plate to clean the upper surface of the screen printing plate. At this time, the rotation of the reciprocating screw drives the threaded slider to perform a small reciprocating motion in the horizontal direction, and then cooperates with the push rod to drive the T-shaped plate to reciprocate left and right along the inner wall of the bottom of the cleaning plate, so that the lever can push and pull the wire brush bristles horizontally to improve the cleaning effect of the wire brush bristles on the residual ink on the screen printing plate.

[0025] like Figure 1-Figure 7 As shown, the utility model provides a technical solution: a screen printing machine that is easy to flush, including a body 1, a screen printing plate 2 is provided on the upper surface of the body 1, a top bracket 3 is hinged on the top of the body 1, a fixing bracket 4 is fixedly connected to the lower surface of the top bracket 3, a scraper 5 is slidably connected to the side wall of the fixing bracket 4, a printing groove 6 is opened on the inner wall of the end of the body 1, and a cleaning component 7 is provided inside the body 1, and the cleaning component 7 includes a driving motor 71, a threaded rod 72, a threaded sleeve 73, a cleaning plate 74, an elastic telescopic rod 75, a connecting rod 76, a protruding rod 77, a guide groove 78, an insert block 79, a baffle 710, a slide plate 711, a shift block 712, a driving plate 713, a coil spring 714, a connecting block 715 and a spring 716.

[0026] In one embodiment of the present invention, the drive motor 71 is fixedly mounted on the outer wall of the end portion of the body 1, the output end of the drive motor 71 is fixedly connected to a threaded rod 72, the outer wall of the threaded rod 72 is threadedly connected to a threaded sleeve 73, the side wall of the threaded sleeve 73 is fixedly connected to a cleaning plate 74, an elastic telescopic rod 75 is fixedly mounted on the inner wall of the body 1, the top of the elastic telescopic rod 75 is movably connected to a connecting rod 76, the side wall of the connecting rod 76 is fixedly connected to a convex rod 77, a guide groove 78 is provided on the inner wall of the side of the body 1, and the convex rod 77 is arranged on the guide groove Inside the groove 78, an insert block 79 is fixedly installed on the outer wall of the side of the connecting rod 76 away from the protruding rod 77, a baffle 710 is provided on the upper surface of the connecting rod 76, a slide plate 711 is slidably installed on the top inner wall of the body 1, and a shift block 712 is fixedly installed on the upper surface of the slide plate 711. The side wall of the threaded sleeve 73 is rotatably connected to a driving plate 713, and a coil spring 714 is provided on the outer surface of the rotating shaft of the driving plate 713. The lower surface of the screen printing plate 2 is fixedly connected to a connecting block 715, and a spring 716 is fixedly connected between the connecting block 715 and the inner wall of the body 1.

[0027] Furthermore, the fixing frame 4 and the top bracket 3 are arranged in parallel, and rectangular grooves are provided on the left and right sides of the fixing frame 4, and rectangular blocks adapted to the rectangular grooves are provided on the left and right sides of the scraper 5, so that the scraper 5 can only slide along the outer surface of the fixing frame 4. After the top bracket 3 is pressed down, the fixing frame 4 and the screen printing plate 2 remain parallel. At this time, the bottom surface of the scraper 5 is in contact with the upper surface of the screen printing plate 2. The staff pushes the scraper 5 laterally along the outer surface of the fixing frame 4 so that the bottom end of the scraper 5 scrapes the upper surface of the screen printing plate 2 from right to left, thereby printing the corresponding pattern. At the same time, the printing groove 6 is arranged below the screen printing plate 2 to realize printing.

[0028] In addition, there are two groups of drive motors 71, and the two groups of drive motors 71 are symmetrically arranged with the vertical central axis of the body 1 as the symmetry axis, and the two groups of drive motors 71 are controlled by the same console so that the drive motors 71 start and shut down synchronously, and the power of the two groups of drive motors 71 is consistent, thereby driving the threaded rods 72 to rotate at the same speed and in the same direction, and then synchronously controlling the threaded sleeves 73 on the left and right sides of the body 1 to move in the same direction and at the same speed along the upper surface of the body 1, and the two ends of the cleaning plate 74 are fixedly connected to the side walls of the threaded sleeves 73 on the left and right sides of the body 1, and the threaded sleeves 73 slide along the upper surface of the body 1, and cooperate with the cleaning plate 74 to clean the upper surface of the screen printing plate 2. Specifically, the lower surface of the cleaning plate 74 is provided with steel wire bristles, and the ink residual on the surface of the screen printing plate 2 is cleaned by the lateral movement of the cleaning plate 74 and the steel wire bristles.

[0029] The cam 76 is provided with a plurality of grooves 720 that are adapted to the outer diameter of the elastic telescopic rod 75, and the top of the elastic telescopic rod 75 is slidably connected to the top inner surface of the square groove, so that the elastic telescopic rod 75 can push the connecting rod 76 in the vertical direction without affecting the lateral sliding of the connecting rod 76. Furthermore, the guide groove 78 is arranged in a "factory" shape, so that the connecting rod 76 moves laterally and then moves downward under the influence of the protruding rod 77 and the guide groove 78. Specifically, the number of connecting blocks 715 is set. There are four groups of connecting blocks 715, and the four groups of connecting blocks 715 are distributed in a rectangular array around the bottom surface of the screen printing plate 2, thereby providing an upward support force for the screen printing plate 2 at the bottom. In addition, the bottom end of the spring 716 is fixedly connected to the inner wall of the body 1, and a socket adapted to the plug block 79 is opened on the side wall of the connecting block 715, so that when the plug block 79 is in the socket, the position of the connecting block 715 is limited, thereby limiting the stability of the screen printing plate 2, so as to ensure the stability of the screen printing plate 2 during the printing process and thus ensure the printing quality of the device.

[0030] At the same time, the upper surface of the body 1 is provided with an offset groove whose width is adapted to the width of the baffle 710, and a sliding groove whose width is adapted to the slide plate 711 is provided on the inner wall of the offset groove. The width of the shift block 712 is adapted to the width of the baffle 710, and the driving plate 713, the shift block 712 and the baffle 710 are arranged in the same plane. Further, when the threaded sleeve 73 slides along the upper surface of the body 1, the driving plate 713 drives the shift block 712, so that the shift block 712 will drive the slide plate 711 to slide toward the side of the baffle 710, and after the shift block 712 contacts the baffle 710, it will drive the baffle 710 and connecting rod 76 slide to the right along the inner wall of the body 1. At this time, due to the guidance and restriction of the protruding rod 77 and the guide groove 78, after the connecting rod 76 and the baffle 710 move to the right for a certain distance, the insert block 79 releases the limit on the connecting block 715. Then the connecting rod 76 drives the baffle 710 to move downward to below the slide plate 711. Then, due to the obstruction of the slide plate 711, the connecting rod 76 no longer moves upward. At this time, as the threaded sleeve 73 continues to rotate with the threaded rod 72, it makes a linear motion along the upper surface of the body 1, thereby driving the cleaning plate 74 to clean the upper surface of the screen printing plate 2.

[0031] When the cam 712 is in the unlocking state, the cam 713 is locked and the locking cam 714 is unlocked, so that the cam 713 can be unlocked easily.

[0032] In an embodiment of the present utility model, a swing assembly 8 is provided inside the threaded sleeve 73, and the swing assembly 8 includes a contact wheel 81, which is rotatably mounted on the inner wall of the threaded sleeve 73, and the contact wheel 81 is coaxially fixedly mounted with a driving wheel 82, and the driving wheel 82 is connected to a driven wheel 84 through a synchronous belt 83. A reciprocating screw 85 is passed through and fixedly mounted on the axis of the driven wheel 84, and a threaded slider 86 is threadedly connected to the outer wall of the reciprocating screw 85. One end of a push rod 87 is hinged on the side wall of the threaded slider 86, and the other end of the push rod 87 is hinged to a T-shaped plate 88, and a shift rod 89 is fixedly mounted on the side wall of the T-shaped plate 88.

[0033] Specifically, the bottom end surface of the contact wheel 81 contacts the upper surface of the machine body 1, and the contact wheel 81 is driven to rotate continuously along the sliding instrument of the upper surface of the machine body 1 through the threaded sleeve 73. In addition, the left and right outer walls of the threaded slider 86 are slidably connected to the inner wall of the threaded sleeve 73, thereby guiding and restricting the movement of the threaded slider 86, so that the threaded slider 86 can only slide horizontally along the inner wall of the threaded sleeve 73 as the reciprocating screw 85 rotates. Furthermore, a T-shaped groove is provided on the lower surface of the cleaning plate 74 that is compatible with the T-shaped plate 88, so that the T-shaped plate 88 can only move horizontally along the inner wall of the T-shaped groove. At the same time, the number of the shifting rod 89 There are several groups of levers 89, which are arranged in a linear array on the side wall of the T-shaped plate 88, and each group of levers 89 is provided with two, and the two levers 89 are mirror-imaged on the left and right sides of the T-shaped plate 88. The threaded sleeve 73 slides along the upper surface of the machine body 1 and drives the cleaning plate 74 to clean the upper surface of the screen printing plate 2. At this time, the rotation of the reciprocating screw 85 drives the threaded slider 86 to perform a small reciprocating motion in the horizontal direction, and then cooperates with the push rod 87 to drive the T-shaped plate 88 to reciprocate left and right along the bottom inner wall of the cleaning plate 74, so that the lever 89 can push and pull the wire brush bristles horizontally to improve the cleaning effect of the wire brush bristles on the residual ink on the screen printing plate 2.

[0034] In the present invention, when in use, the top bracket 3 is pressed down so that the fixing bracket 4 remains parallel to the screen printing plate 2. The staff pushes the scraper 5 laterally along the outer surface of the fixing bracket 4 so that the bottom end of the scraper 5 scrapes the upper surface of the screen printing plate 2 from right to left, thereby printing the corresponding pattern. After printing is completed, the top bracket 3 is pushed upward to break away from contact with the screen printing plate 2. At this time, the drive motor 71 is started and the threaded rod 72 is cooperated so that the threaded sleeve 73 will move laterally in the horizontal direction along the upper surface of the body 1, and cooperate with the steel wire brush under the cleaning plate 74 to clean the ink remaining on the surface of the screen printing plate 2.

[0035] At the same time, by providing the cleaning assembly 7, when the threaded sleeve 73 starts to move, the driving plate 713 drives the shift block 712 slide plate 711 to slide toward the side of the baffle 710. After the shift block 712 hits the baffle 710, it drives the baffle 710 and the connecting rod 76 to slide to the right along the inner wall of the body 1. At this time, due to the guidance and restriction of the protruding rod 77 and the guide groove 78, after the connecting rod 76 and the baffle 710 move to the right a certain distance, the plug block 79 releases the limit of the connecting block 715, and then the connecting rod 76 drives the baffle 710 to slide to the right. It moves downward to the bottom of the slide plate 711, and then due to the obstruction of the slide plate 711, the connecting rod 76 no longer moves upward. At this time, as the threaded sleeve 73 continues to rotate with the threaded rod 72, it moves linearly along the upper surface of the body 1, thereby driving the cleaning plate 74 to clean the upper surface of the screen printing plate 2. At the same time, through the influence of the wire brush on the screen printing plate 2, combined with the spring 716 and the connecting block 715, the cleaned screen printing plate 2 will vibrate slightly up and down to improve the cleaning effect of the wire brush.

[0036] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
