Description

Technical Field

[0001] The invention relates to the technical field of printing, and in particular to a printing machine. Background Art

[0002] At present, there are two types of screen printing, one is flat screen printing and the other is rotary screen printing. Although the production speed of flat screen printing is not as fast as that of rotary screen printing, the plate making cost of flat screen printing is lower than that of rotary screen printing, and the printing plate cycle is longer, and the contact time between the grey cloth and the printing screen is longer. It is suitable for printing fabrics such as terry cloth, and is also more suitable for small batch fine printing. Since the promotion and application of rotary screen printing in the 1960s, it has developed rapidly and has accounted for nearly 60% of the total fabric printing volume, and more than 90% in Western Europe. Rotary screen printing has the advantages of fast printing speed and high degree of automation. The above two printing methods are used in different occasions according to their own characteristics and needs.

[0003] The existing printing machine, whether it is a flat screen printing machine or a rotary screen printing machine, generally includes a screen assembly, a magnetic table arranged below the screen assembly, and a printing guide belt arranged between the screen assembly and the magnetic table. The magnetic bar in the screen assembly is adsorbed on the fabric on the printing guide belt by the magnetic table, and the magnetic bar is driven to move on the screen assembly by the magnetic table to achieve printing. However, since the magnetic table adsorbs the magnetic bar on the magnetic table through the printing guide belt, when the magnetic table is uneven or the adsorption force of the magnetic table on the magnetic bar changes, the pressure of the magnetic bar on the fabric changes, which makes the printing on the fabric uneven and the printing quality poor. Summary of the invention

[0004] The purpose of the present invention is to provide a printing machine, in which a magnetic rod is always attached to the cloth, so as to avoid uneven printing caused by the magnetic rod being unable to adhere to the cloth due to the unevenness of the magnetic table or the change in the adsorption force of the magnetic table on the magnetic rod.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] The present invention provides a printing machine, comprising a screen assembly, a magnetic table located below the screen assembly, and a printing guide belt for conveying cloth arranged between the screen assembly and the magnetic table, wherein a magnetic rod is arranged in the screen assembly, and the magnetic table drives the magnetic rod to move, wherein a magnetic rod is arranged in the screen assembly, and two protruding structures are arranged at intervals on the top of the magnetic table, and the magnetic table adsorbs the magnetic rod between the two protruding structures and causes the printing guide belt to be recessed toward the direction close to the magnetic table.

[0007] The printing machine arranges two raised structures at intervals on the top of the magnetic table, and adsorbs the magnetic rod between the two raised structures through the magnetic table, so that the magnetic rod presses down the printing conductive tape and makes the printing conductive tape concave toward the magnetic table, so that the magnetic rod and the fabric on the printing conductive tape can fully fit together, and prevent the magnetic rod from being unable to adhere to the fabric due to the unevenness of the magnetic table or the change in the adsorption force of the magnetic table on the magnetic rod, thereby preventing uneven printing.

[0008] As a preferred solution of the above-mentioned printing machine, the two protruding structures are arranged along a direction perpendicular to the conveying direction of the printing blanket, so that the supporting effect of the protruding structures on the printing blanket is evenly distributed during the movement of the fabric driven by the printing blanket.

[0009] As a preferred solution of the above-mentioned printing machine, the distance between the two protruding structures is greater than the diameter of the magnetic rod. This arrangement can prevent the magnetic rod from being over-pressed and abutting against the protruding structures through the printing conductive tape.

[0010] As a preferred solution of the above-mentioned printing machine, the protruding structure is a cylindrical structure, which can facilitate the smooth transportation of the printing guide.

[0011] As a preferred solution of the above-mentioned printing machine, the top of the protruding structure is a curved surface structure, which can facilitate the smooth transportation of the printing guide belt through the curved surface structure.

[0012] As a preferred solution of the above-mentioned printing machine, the magnetic table includes a magnetic table frame and a magnet assembly arranged in the magnetic table frame, and two protrusion structures are arranged on the top of the magnetic table frame, and the two protrusion structures are respectively located on both sides of the magnet assembly.

[0013] As a preferred solution of the above-mentioned printing machine, the magnet assembly is arranged perpendicular to the conveying direction of the printing guide. This structure can provide sufficient adsorption force for the magnetic rod, and the adsorption effect is strong.

[0014] As a preferred solution of the above-mentioned printing machine, the screen assembly includes a support frame and a printing screen arranged at the bottom of the support frame, and the magnetic rod is placed on the printing screen.

[0015] As a preferred solution of the above-mentioned printing machine, the support frame is arranged around the circumference of the printing screen. The support frame is arranged around the circumference of the printing screen to support and fix the printing screen.

[0016] As a preferred solution of the above-mentioned printing machine, the printing blanket is made of elastic material. The printing blanket is made of elastic material, so that when the magnetic rod is adsorbed by the magnetic table, it can press the printing blanket downward to produce a concave effect.

[0017] Beneficial effects of the present invention:

[0018] The printing machine proposed in the present invention arranges two protruding structures at intervals on the top of the magnetic table, and adsorbs the magnetic rod between the two protruding structures through the magnetic table, so that the magnetic rod presses down the printing conductive tape, and the printing conductive tape is recessed toward the magnetic table, so that the magnetic rod and the cloth on the printing conductive tape can be fully fitted together, and the magnetic table can be prevented from being unable to adhere to the cloth due to the unevenness of the magnetic table and the change in the adsorption force of the magnetic table on the magnetic rod, thereby preventing uneven printing.

[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0024] This embodiment provides a printing machine, such as Figure 1 As shown, the printing machine includes a screen assembly 1, a magnetic table 2 located below the screen assembly 1, and a printing guide 3 for conveying fabrics arranged between the screen assembly 1 and the magnetic table 2. A magnetic rod 4 is arranged in the screen assembly 1, and the magnetic table 2 drives the magnetic rod 4 to move. Two protrusion structures 21 are arranged at intervals on the top of the magnetic table 2. The magnetic table 2 adsorbs the magnetic rod 4 between the two protrusion structures 21, and makes the printing guide 3 concave toward the direction close to the magnetic table 2, but the printing guide 3 does not contact the magnetic table 2, so that the magnetic rod 4 can be fully fitted with the fabric on the printing guide 3, and the magnetic table 2 is not flat or the magnetic table 2 changes the adsorption force of the magnetic rod 4, which causes the magnetic rod 4 to be unable to adhere to the fabric and thus causes uneven printing. In this embodiment, the printing guide 3 is made of elastic material, so that when the magnetic rod 4 is adsorbed by the magnetic table 2, it can press the printing guide 3 downward to produce a concave effect. The printing machine can be a flat screen printing machine or a round screen printing machine. In this embodiment, a flat screen printing machine is specifically described.

[0025] The magnetic table 2 is connected to a driving device (not shown in the figure), and the driving device drives the magnetic table 2 to move in the forward and reverse directions along the conveying direction of the printing guide 3. The driving device drives the movement of the magnetic table 2, which is common knowledge in the art. As long as the linear motion of the magnetic table 2 can be achieved, it will not be described here. Specifically, the movement of the magnetic table 2 drives the magnetic rod 4 to move, and then the printing dye on the screen assembly 1 is printed on the cloth on the printing guide 3 through the screen assembly 1. In this embodiment, when printing, the magnetic table 2 drives the magnetic rod 4 to move in the forward direction of the conveying direction of the printing guide 3, and then moves it in the reverse direction of the conveying direction of the printing guide 3 to print the cloth again. By printing the cloth twice, the printing effect is enhanced.

[0026] Specifically, the magnetic table 2 includes a magnetic table frame 22 and a magnet assembly 23 arranged in the magnetic table frame 22. Two protrusion structures 21 are arranged on the top of the magnetic table frame 22. The two protrusion structures 21 are respectively located on both sides of the magnet assembly 23, so that the magnetic rod 4 can be adsorbed between the two protrusion structures 21 through the adsorption effect of the magnetic table 2.

[0027] Specifically, the two raised structures 21 are arranged along a direction perpendicular to the conveying direction of the printing guide 3. This arrangement allows the supporting effect of the raised structures 21 on the printing guide 3 to be evenly distributed during the movement of the fabric driven by the printing guide 3. The raised structure 21 is arranged to protrude from the magnetic table 2. In this embodiment, the top surface of the raised structure 21 is 5 cm higher than the top surface of the magnetic table 2. Furthermore, the distance between the two raised structures 21 is greater than the diameter of the magnetic rod 4. This arrangement enables the magnetic rod 4 to press the printing guide 3 downward to produce a concave effect, thereby preventing the magnetic rod 4 from being over-pressed and fitting with the raised structure 21 through the printing guide 3. Figure 1 As shown, the protruding structure 21 is a cylindrical structure, which can facilitate the smooth transportation of the printing blanket 3. In this embodiment, the distance between the axes of the two cylindrical protruding structures 21 is 42 cm, and the diameter of the magnetic rod 4 is 15 cm. It is also possible to make only the top of the protruding structure 21 a curved surface structure, which can facilitate the smooth transportation of the printing blanket 3. For example, the protruding structure 21 is a semi-cylindrical structure, which is conducive to the movement of the printing blanket 3.

[0028] The magnet assembly 23 is arranged perpendicular to the conveying direction of the printing guide 3. This structure can provide sufficient adsorption force for the magnetic bar 4, and the adsorption effect is strong. When the magnetic bar 4 is adsorbed on the magnetic table 2, the magnetic bar 4 is parallel to the magnet assembly 23 and the two protrusion structures 21.

[0029] like Figure 1As shown, the screen assembly 1 includes a support frame 11 and a printing screen 12 arranged at the bottom of the support frame 11. The printing screen 12 is detachably arranged on the support frame 11. The specific printing screen 12 can be detachably connected by snap connection, slide connection, fixing connection, etc. The specific detachable connection method of the printing screen 12 and the support frame 11 can be set according to the needs. The printing screen 12 is detachably connected to the support frame 11, which is convenient for replacing the printing screen 12. The magnetic bar 4 is placed on the printing screen 12. Preferably, the support frame 11 is arranged around the circumference of the printing screen 12. The support frame 11 is arranged around the circumference of the printing screen 12 to support and fix the printing screen 12. In this embodiment, the printing machine is a flat screen printing machine, and the above-mentioned printing screen 12 is a flat screen. When the printing machine is a round screen printing machine, the above-mentioned printing screen 12 is a round screen.

[0030] When printing the fabric, printing dye is added to the printing screen 12, and the magnetic table 2 is driven to move by the driving device. The magnetic table 2 drives the magnetic rod 4 to move along the positive direction of the conveying direction of the printing blanket 3 through adsorption, and then moves along the reverse direction of the conveying direction of the printing blanket 3.

[0031] Then, the printed fabric is moved by the printing guide 3, and the magnetic table 2 drives the magnetic bar 4 to repeat the above steps for the fabric to be printed. The moving distance of the magnetic bar 4 driven by the magnetic table 2 is set according to the length of the printing screen 12.

[0032] Note that the above are only preferred embodiments of the present invention. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
