Description

Technical Field

[0001] The utility model belongs to the technical field of metal plate printing, and in particular relates to a plate material line drawing device. Background Art

[0002] During the production process of the tank body, the sheet material needs to be cut into appropriate widths, and then printed on the sheet material of appropriate width to achieve the purpose of identification, decoration, advertising, etc. Drawing identification lines on the metal sheet material can help workers quickly align and calibrate the various parts on the sheet material, which is convenient for subsequent laser cutting and easy for subsequent processing after cutting.

[0003] In the existing marking device (such as CN202022275713.2), the sheet is placed still and the marking line is drawn on the sheet by controlling the movement of the marking pen. However, this marking method is slow and the drawing rate is low, which affects the speed of subsequent laser cutting. Utility Model Content

[0004] The utility model aims to provide a plate material marking device to solve the problems of slow marking speed and low marking rate.

[0005] To achieve the above object, the utility model provides the following technical solutions: a plate marking device, comprising a conveyor belt, one side of the conveyor belt is provided with two groups of marking mechanisms, the two groups of marking mechanisms are symmetrically arranged up and down, and a pulling mechanism is provided on the side of the marking mechanism away from the conveyor belt;

[0006] The marking mechanism comprises two rows of marking pens, which comprise an outer shell, an inner rod, a ball bearing and an elastic member. The outer shell is sleeved on the inner rod, the ball bearing can be rolled on the bottom of the inner rod, and the elastic member is arranged in the outer shell.

[0007] Furthermore, two ends of the elastic member respectively abut against the top of the inner cavity of the shell and the top of the inner rod.

[0008] Furthermore, the liner pen is provided with a color injection tube, and the color injection tube can be bent.

[0009] Furthermore, a pressing block is arranged above the conveyor belt, and the bottom of the pressing block is arc-shaped on the side away from the line drawing mechanism.

[0010] Furthermore, the line drawing mechanism also includes a mounting block, and an injection hole is provided on the mounting block.

[0011] Furthermore, the two rows of markers are both installed at the bottom of the mounting block, and the two rows of markers are staggered with each other.

[0012] Furthermore, the pulling mechanism includes two rollers, and the two rollers rotate in opposite directions.

[0013] Furthermore, the pulling mechanism also includes a first gear and a second gear which are respectively fixedly sleeved on two roller shafts, and the first gear and the second gear are meshed and connected.

[0014] Furthermore, the marking pen is provided with a thread groove.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The plate marking device places the plate on a conveyor belt and uses two marking pens to mark the upper and lower sides of the plate. During the process, the plate is always moving without intermittent motion, which speeds up the plate marking speed and thus improves the subsequent laser cutting speed.

[0017] The plate marking device utilizes the elastic restoring force of the elastic member, so that the marking pen can maintain stable contact with the plate when the plate shakes up and down, and always maintain contact with the plate through the deformation and restoration of the elastic member, thereby avoiding the pen jumping phenomenon;

[0018] The plate marking device can change the spacing between marking pens in the same row by reducing or increasing the number of marking pens in the same row, and can draw marking lines with different spacings, so that the device has high flexibility and can meet the needs of marking lines with different spacings.

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with embodiments.

[0025] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0026] See also Figure 1 and Figure 2 The utility model provides a plate marking device, comprising two side plates 10 parallel to each other, and a conveyor belt 20, a marking mechanism 30 and a pulling mechanism 40 are sequentially arranged from left to right between the two side plates 10 close to each other;

[0027] The sheet material 50 is placed on the conveyor belt 20 and conveyed to the right by the conveyor belt 20 so that the sheet material 50 passes through the line drawing mechanism 30 to draw a marking line, and then the sheet material 50 is pulled by the pulling mechanism 40 to provide a rightward pulling force for the sheet material 50 .

[0028] A pressing block 110 is arranged above the conveyor belt 20 . The left side of the bottom of the pressing block 110 is arc-shaped. The pressing block 110 can limit the position of the sheet material 50 .

[0029] See also Figure 3 and Figure 4 There are two marking mechanisms 30, which are symmetrically located above and below the sheet material 50. The two marking mechanisms 30 mark both sides of the sheet material 50 at the same time, thereby speeding up the marking speed. The marking mechanism 30 includes a mounting block 310 and two rows of marking pens 320. The front and rear sides of the mounting block 310 are respectively connected to the sides of the two side panels 10 that are close to each other. The left row of marking pens 320 and the right row of marking pens 320 are staggered with each other. The right row of marking pens 320 can mark the gaps between the left row of marking pens 320, thereby drawing marking lines at different positions.

[0030] A thread groove 321 is provided on the top of the marker pen 320, and the marker pen 320 is threadedly sleeved on the bottom of the mounting block 320 through the thread groove 321. By removing or installing the marker pen 320, the number of marker pens 320 in the same row can be reduced or increased to change the spacing between the marker pens 320 in the same row, and marking lines with different spacings can be drawn.

[0031] See also Figure 3 and Figure 4The marker pen 320 includes a shell 322, an inner rod 323, a ball 324, and an elastic member 325. The top of the inner rod 323 is arranged inside the shell 322, and the inner rod 323 can be received in the shell 322. The bottom of the inner rod 323 is conical, and the ball 324 can be rolled at the bottom of the inner rod 323. The ball 324 is rolled to draw lines. The elastic member 325 is arranged in the shell 322. The two ends of the elastic member 325 respectively contact the top of the inner cavity of the shell 322 and the top of the inner rod 323. The elastic member 325 provides an outward thrust for the inner rod 323. The marker pen 320 is provided with a color injection tube 326. The upper and lower ends of the marker pen 320 are fixedly sleeved with the shell 322 and the inner rod 323 respectively, and the color injection tube 326 passes through the elastic member 325. The color injection tube 326 can be bent or folded to avoid the problem that the inner rod 323 cannot be received into the shell 322 due to the color injection tube 326.

[0032] The marker pens 320 on the upper and lower sides have a certain clamping force under the action of the elastic member 325, and can be retracted and extended. The marker pens 320 on the upper and lower sides always maintain contact and clamping with the sheet material 50 points, avoiding the problem of intermittent marking lines with different depths and a single line.

[0033] See also Figure 1-4 The top of the mounting block 310 is provided with the same number of injection holes 311 as the number of the liner pens 320, so that the pigment can be injected into the injection tube 326 without disassembly.

[0034] See also Figure 1 The pulling mechanism 40 includes a motor 410, a first gear 420, a second gear 430 and two roller shafts 440. The first gear 420 and the second gear 430 are respectively fixedly sleeved on the two roller shafts 440. The two roller shafts 440 are arranged up and down. The first gear 420 and the second gear 430 are meshed and connected. The rotating shaft of one of the roller shafts 440 is installed on the output shaft of the motor 410.

[0035] The motor 410 drives two gears to drive the two rollers 440 to rotate in opposite directions. The movement direction of the two rollers 440 that are close to each other is rightward, so that the sheet 50 moves to the right due to the friction of the two rollers 440 and moves out of the drawing device.

[0036] The working principle and use process of the utility model are as follows: according to the line drawing requirements, one row of line drawing pens 320 or two rows are selected and retained at the same time, the line drawing pens 320 at some positions are disassembled or assembled, and the spacing between the line drawing pens 320 in the same row is changed, so that marking lines with different spacings can be drawn;

[0037] The sheet material 50 is placed on the conveyor belt 20 and conveyed to the right by the conveyor belt 20. The sheet material 50 passes through the marking mechanism 30 and enters the pulling mechanism 40. The marking pens 320 on the upper and lower sides have a certain clamping force under the action of the elastic member 325. The marking pens 320 on the upper and lower sides always maintain point contact and clamping with the sheet material 50 to avoid the problem of intermittent depth and uneven line marks of the marking line. Driven by the motor 410, the two gears drive the two rollers 440 to rotate in opposite directions. The movement direction of the side where the two rollers 440 are close to each other is all to the right, so that the sheet material 50 moves to the right under the friction of the two rollers 440 and moves out of the marking device.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
