[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The embodiment of the present invention provides an automatic sheet feeding machine for side coding of a friction plate, comprising a first sheet feeding component 1, a second sheet feeding component 2, a coding auxiliary component 3 and a sheet feeding stacking component 4; illustratively, Figure 1 and Figure 2 shown.

[0036] One end of the first sheet feeding assembly 1 is rotatably connected to one end of the second sheet feeding assembly 2, the coding auxiliary assembly 3 is arranged on the top of the first sheet feeding assembly 1, and the sheet feeding stacking assembly 4 is arranged at the end of the second sheet feeding assembly 2 and away from the side of the first sheet feeding assembly 1.

[0037] Specifically, the coding auxiliary component 3 divides the friction plate on the first sheet feeding component 1 so that the rear friction plate of the divided material can realize synchronous double-row sheet feeding, and adjusts the position of the friction plates on both sides under the action of the coding auxiliary component 3 so that the adjusted friction plates are uniformly set at the coding port, which is convenient for the uniformity of the friction plate coding position;

[0038] The connection between the second sheet feeding component 2 and the first sheet feeding component 1 is rotated and adjusted so that a gap is formed between the adjusted first sheet feeding component 1 and the second sheet feeding component 2, and a corner conveyor belt is placed in the gap to meet the needs of the sheet feeding machine for terrain changes. The sheet feeding and stacking component 4 is then used to grab and place the friction sheets after coding, so as to automate the unloading operation of the friction sheets after batch coding.

[0039] The first sheet feeding assembly 1 includes two sets of first vertical plates 12; illustratively, Figure 3 , Figure 4 and Figure 5 shown.

[0040] A plurality of first sheet feeding rollers 11 are arranged between the two groups of the first vertical plates 12, and the plurality of first sheet feeding rollers 11 are arranged at the same level. A top sheet plate 14 is slidably connected between the two groups of the first vertical plates 12, and a reserved opening 15 is provided at the top of the top sheet plate 14, and the reserved opening 15 is sleeved on the outside of the inkjet auxiliary component 3. The output ends of the first electric push rods 13 are both transmission-connected to the two sides of the bottom of the top sheet plate 14, and the sides of the two groups of the first electric push rods 13 away from the output ends are fixedly connected to the inner wall of the first vertical plate 12, and one end of the two groups of the first vertical plates 12 is fixedly connected to a hinge column 16, and an axle pin 17 is provided on the hinge column 16;

[0041] A coding port 18 is provided at the top of the two groups of the first vertical plates 12, and a coding device is installed on the outer wall of the two groups of the first vertical plates 12 and near the coding port 18. Two groups of second electric push rods 19 are fixedly connected to the top of the first vertical plates 12, and the two groups of the second electric push rods 19 are symmetrically arranged with the central axis of the coding port 18 as the center. The output ends of the two groups of the second electric push rods 19 are transmission connected to the limiting cover 110, and the bottom of the limiting cover 110 is clamped on the coding port 18. The top of the limiting cover 110 is slidably connected to the air pump 111, and the output end of the air pump 111 is connected to the air supply pipe 112. A first screw rod 113 is threadedly connected to one side wall of the air pump 111, and both ends of the first screw rod 113 are transmission connected to the output end of the first motor 114, and the side of the two groups of the first motors 114 away from the output end is fixedly connected to the top of the limiting cover 110.

[0042] Specifically, the first sheet feeding roller 11 conveys the friction sheet horizontally. When the friction sheet moves to the inkjet printing port 18, the second electric push rod 19 drives the limit cover 110 to fall, so that the limit cover 110 blocks the inkjet printing port 18, so as to prevent the friction sheet from being stuck in the inkjet printing port 18 when the friction sheet position is rotated and adjusted, and the friction sheet cannot be rotated and adjusted.

[0043] The first motor 114 drives the first screw rod 113 to rotate, so that the air pump 111 moves horizontally along the radial direction of the first screw rod 113. When the air pump 111 continues to work, gas is injected into the air pipe 112, so that the gas is blown to different positions near the inkjet printing port 18, so that the friction plate before inkjet printing can be cleaned at different positions, and the pattern can be quickly dried after inkjet printing.

[0044] The second sheet feeding assembly 2 includes two sets of second vertical plates 21; illustratively, as Figure 6 shown.

[0045] A plurality of second film feeding rollers 22 are rotatably connected between the two groups of the second vertical plates 21, and the plurality of second film feeding rollers 22 are arranged at the same level. A hinge seat 23 is provided at one end of the two groups of the second vertical plates 21, and the hinge seat 23 is movably clamped at the two ends of the shaft pin 17. A limit plate 24 is provided on the inner wall of the two groups of the second vertical plates 21, and a bolt 25 is rotatably connected to the outer wall of the limit plate 24. The bolt 25 is threadedly connected to the second vertical plate 21, and the limit plate 24 is made of elastic plastic material. A third electric push rod 26 is fixedly connected to the top of the two groups of the second vertical plates 21 and the side away from the hinge seat 23, and the output ends of the two groups of the third electric push rods 26 are transmission connected to the film feeding and stacking assembly 4.

[0046] Specifically, in the process of several groups of the second sheet feeding rollers 22 moving the coded friction plate horizontally between the two groups of limiting plates 24, the friction plate is limited by the two groups of limiting plates 24 to reduce the distance between the two groups of friction plates, thereby facilitating the grabbing of the friction plate and the sheet feeding stacking assembly, and the distance between the two groups of limiting plates 24 is adjusted by rotating the bolts 25 to facilitate the use with friction plates of different sizes.

[0047] The coding auxiliary component 3 includes an isolation plate 31; illustratively, Figure 7 shown.

[0048] A plurality of groups of bearings 32 are arranged at the bottom of the isolation plate 31, and the plurality of groups of bearings 32 are rotatably connected to the central axis of the first sheet feeding roller 11. An adjusting groove 33 is opened at the top of the isolation plate 31, and an electric slide is arranged at the bottom end of the inner wall of the adjusting groove 33. The top of the electric slide is transmission-connected with two groups of pneumatic clamps 34, and both groups of pneumatic clamps 34 are scissor-type clamps. The tops of the two groups of pneumatic clamps 34 are fixedly connected with a second motor 35, and the output ends of the second motor 35 are transmission-connected with friction rollers 36. The two groups of friction rollers 36 are distributed on both sides of the isolation plate 31.

[0049] Specifically, the isolation plate 31 uses a plurality of groups of bearings 32, so that the bearings 32 are rotatably connected to the first sheet feeding roller 11, and the isolation plate 31 is in the function of separating the first sheet feeding roller 11, while the isolation plate 31 itself does not move horizontally along the radial direction of the first sheet feeding roller 11, and the electric slide in the adjustment slot 33 drives the two groups of pneumatic clamps 34 to adjust the spacing between the two groups of pneumatic clamps 34 to meet the clamping effect of friction plates with different diameters;

[0050] When the two groups of pneumatic clamps 34 drive the friction roller 36 to move, they resist the friction plate moved to the inkjet printing port 18, and the other side of the friction plate resists the limit cover 110, so that the friction plate is in a positioned state, and then the second motor 35 is used to drive the friction roller 36 to rotate, so that the friction plate is horizontally rotated along the rotation direction of the friction roller 36 under the action of rolling contact with the first sheet feeding roller 11 at the bottom, so as to adjust the fixed position of the side of the friction plate to the attachment of the inkjet printing port 18, so as to facilitate the precise positioning and adjustment of the inkjet printing position.

[0051] The sheet feeding and stacking assembly 4 includes a stacking housing 41; illustratively, as Figure 8 and Fig. 9 shown.

[0052] The stacked housing 41 has a C-shaped structure, and the top end of the inner wall of the stacked housing 41 is fitted and connected with a vacuum housing 42. One side wall of the vacuum housing 42 is provided with a vacuum pump 43, and several groups of suction nozzles 44 are arranged at the bottom of the vacuum housing 42. A hollow sliding cavity 45 is formed in one side wall of the stacked housing 41. A linkage arm 46 is slidably and fittingly connected to the inner wall of the hollow sliding cavity 45, and one end of the linkage arm 46 is fixedly connected to the outer wall of the vacuum housing 42. A second lead screw 47 is threadedly connected to the linkage arm 46. An angle adjustment arm 48 is arranged at the top of the stacked housing 41, and the central axis center of the angle adjustment arm 48 coincides with the central axis center of the second lead screw 47. Both ends of the angle adjustment arm 48 are drivingly connected to the output ends of the third electric push rods 26. The central axis center of the angle adjustment arm 48 is embedded with a third motor 49. The output end of the third motor 49 extends to the bottom of the angle adjustment arm 48, and the output end of the third motor 49 is drivingly connected to an angle adjustment block 410. The angle adjustment block 410 is fixedly connected to the outer wall of the stacked housing 41. The bottom of the angle adjustment block 410 is embedded with a fourth motor, and the output end of the fourth motor is drivingly connected to the top end of the second lead screw 47.

[0053] Specifically, the output end of the fourth motor drives the second lead screw 47 to rotate, so that the vacuum housing 42 moves radially along the second lead screw 47, which is used to drive the suction nozzles 44 to adsorb the friction plates after inkjet printing. Then, the third electric push rod 26 is used to push the stacked housing 41 away from the second sheet feeding roller 22, so that there is enough stacking space for the adsorbed friction plates. Then, the output end of the fourth motor drives the second lead screw 47 to rotate in the other direction, so that the adsorbed friction plates fall to the bottom of the stacked housing 41 for stacking the friction plates. The output end of the third motor 49 is used to drive the angle adjustment block 410 to rotate, so that the opening of the stacked housing 41 moves to the side away from the second sheet feeding roller 22, which is used to batch unload the stacked friction plates, facilitating the handling of the friction plates after inkjet printing.

[0054] The working principle of an automatic sheet feeding machine for side inkjet printing of friction plates proposed by an embodiment of the present invention is as follows:

[0055] The friction plates are horizontally conveyed by the first sheet feeding roller 11. Before the friction plates move to the inkjet port 18, the second electric push rod 19 is used to drive the limiting cover 110 to fall, so that the limiting cover 110 blocks the inkjet port 18, avoiding that when the position of the friction plates is rotated and adjusted at the open notch of the inkjet port 18, the friction plates are clamped in the inkjet port 18 and the rotation adjustment of the friction plates cannot be carried out.

[0056] The first motor 114 drives the first screw rod 113 to rotate, so that the air pump 111 moves horizontally along the radial direction of the first screw rod 113. When the air pump 111 continues to work, gas is injected into the air pipe 112 to blow gas to different positions near the inkjet printing port 18, so as to clean the friction plate at different positions before inkjet printing and quickly dry the pattern after inkjet printing.

[0057] The isolation plate 31 is used to utilize a plurality of bearings 32, so that the bearings 32 are rotatably connected to the first sheet feeding roller 11, and the isolation plate 31 is in the function of separating the first sheet feeding roller 11, while the isolation plate 31 itself does not move horizontally along the radial direction of the first sheet feeding roller 11, and the electric slide in the adjustment slot 33 is used to drive the two groups of pneumatic clamps 34, so as to adjust the spacing between the two groups of pneumatic clamps 34, so as to meet the clamping effect of friction plates with different diameters;

[0058] In the process of driving the friction roller 36 to move by the two sets of pneumatic clamps 34, the friction plate moved to the inkjet printing port 18 is resisted, and the other side of the friction plate is resisted with the limit cover 110, so that the friction plate is in a positioned state, and then the second motor 35 is used to drive the friction roller 36 to rotate, so that the friction plate is horizontally rotated along the rotation direction of the friction roller 36 under the action of rolling contact with the first sheet feeding roller 11 at the bottom, so as to adjust the fixed position of the side of the friction plate to the attachment of the inkjet printing port 18, so as to facilitate the accurate positioning and adjustment of the inkjet printing position;

[0059] The second screw rod 47 is driven to rotate by the output end of the fourth motor, so that the vacuum shell 42 moves radially along the second screw rod 47, which is used to drive the suction nozzle 44 to adsorb the friction plate after coding, and then the third electric push rod 26 is used to push the stacking shell 41 away from the second sheet feeding roller 22, so that the adsorbed friction plate has enough stacking space, and then the output end of the fourth motor is used to drive the second screw rod 47 to rotate to the other side, so that the adsorbed friction plate falls to the bottom of the stacking shell 41 for stacking the friction plates, and the output end of the third motor 49 is used to drive the angle adjustment block 410 to rotate, so that the opening of the stacking shell 41 moves to the side away from the second sheet feeding roller 22, which is used to batch unload the stacked friction plates, so as to facilitate the transportation of the friction plates after coding.

[0060] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
