DETAILED DESCRIPTION

[0035] The technical solutions 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; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 11 A seat leather printing machine includes a printing machine body 1, a main console unit 2 is arranged on the printing machine body 1, a printing unit 12 is opened on the printing machine body 1, a printing cavity 11 is opened inside the printing unit 12, a printing nozzle 5 for spraying is fixedly arranged inside the printing cavity 11, a pushing platform 3 for conveying leather is also arranged on the printing machine body 1, and a guide component 4 for assisting in placing leather is also arranged on the pushing platform 3. The guide component 4 includes a guide plate 41 fixedly installed on the pushing platform 3, two guide plates 41 are arranged, and the two guide plates 41 are symmetrically arranged, one of the guide plates 41 is fixedly connected to a top plate 42, a fixed head 43 is fixedly installed on the bottom of the top plate 42, a rubber wheel 44 is rotatably arranged inside the fixed head 43, and a first reciprocating screw 45 is rotatably sleeved between the two guide plates 41, and a first push-flattening block 46 is spirally driven on the first reciprocating screw 45.

[0037] One end of the first reciprocating screw 45 extends to the main console unit 2, and a driving motor for rotating the first reciprocating screw 45 is fixedly arranged on the main console unit 2. The main console unit 2 is used to control the opening and closing of the driving motor.

[0038] When printing leather, the worker first needs to place the leather in the guide assembly 4 on the push table 3. With the help of the guide assembly 4, the position of the leather placed on the push table 3 is straightened. Then the push table 3 pushes the leather into the printing chamber 11 for printing. The printing nozzle 5 in the printing chamber 11 sprays the pattern onto the surface of the leather to complete the printing of the leather.

[0039] When the guide assembly 4 is working, the staff first places the leather on the push table 3 with the guide plate 41, aligns the edge of the leather with the inner wall of the guide plate 41 with the fixed head 43, and then the main console unit 2 controls the driving motor to make the first reciprocating screw 45 rotate. When the first reciprocating screw 45 rotates, the first flattening block 46 that is spirally driven with the first reciprocating screw 45 will move back and forth on the first reciprocating screw 45. During the back and forth movement of the first flattening block 46, the first flattening block 46 will smooth the surface of the leather. At the same time, when the staff places the leather on the push table 3, the rubber wheel 44 in the fixed head 43 will fix the leather on a line parallel to the guide plate 41, so as to facilitate the first flattening block 46 to flatten the leather toward the guide plate 41 without the fixed head 43, assist the staff in placing the leather, and facilitate the printing of the leather by the printing nozzle 5.

[0040] like Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, a cutting assembly 7 for cutting printed leather is also provided in the printing cavity 11, and the cutting assembly 7 includes a second reciprocating screw 71 rotatably connected to the inner wall of the printing cavity 11, and cutting heads 72 are fixedly installed on the outer surfaces of both ends of the second reciprocating screw 71 close to the inner wall of the printing cavity 11, and a cutting line groove 31 used in conjunction with the cutting head 72 is provided on the pushing platform 3;

[0041] Two pusher blocks 8 are fixedly mounted on the printing unit 12. Guide blocks 81 used in conjunction with the cutting blade 72 are fixedly mounted at the bottom of the two pusher blocks 8. The two guide blocks 81 are symmetrically arranged. The two guide blocks 81 are tilted near one side of the main console unit 2.

[0042] The transmission member 9 includes a first bevel gear 91 fixedly sleeved on the outer surface of the first reciprocating screw 45, two of the first bevel gears 91 are respectively located on the outer sides of the two guide plates 41, and the two first bevel gears 91 are arranged on the outer sides of the two guide plates 41. A rotating rod 93 is rotatably installed on the printing unit 12, one end of the rotating rod 93 passes through the printing unit 12 to the outside of the printing unit 12, and the other end of the rotating rod 93 passes through the printing unit 12 to the printing cavity 11, and both ends of the rotating rod 93 are fixedly sleeved with a second bevel gear 92, and the first bevel gear 91 and the second bevel gear 92 located outside the printing unit 12 are meshed with each other, and both ends of the second reciprocating screw 71 are fixedly sleeved with a third bevel gear 94, and the third bevel gear 94 and the second bevel gear 92 located inside the printing cavity 11 are meshed with each other;

[0043] Two bellows 61 are provided, and the two bellows 61 are symmetrically arranged. The second reciprocating screw 71 is composed of two mutually symmetrical screws. The second reciprocating screw 71 has a spiral transmission screw sleeve 95, and two screw sleeves 95 are symmetrically arranged. The two screw sleeves 95 correspond to the two screws one by one. The outer surface of each screw sleeve 95 is fixedly installed with an L-shaped plate 96, and one end of the two L-shaped plates 96 is fixedly connected to the two bellows 61 respectively.

[0044] The outer surface of the second reciprocating screw 71 spirally drives two second push-flattening blocks 73, and the two second push-flattening blocks 73 are fixedly connected to the L-shaped plate 96. A movable groove 74 is opened inside each second push-flattening block 73, and a short rod 75 is fixedly installed on the inner wall of the movable groove 74. A hinge 76 is rotatably set on the outer surface of the short rod 75, and a push plate 77 is fixedly installed on the outer surface of the hinge 76. The push plate 77 extends to the outside of the second push-flattening block 73 and contacts with the push platform 3. A latch rod 78 is movably set inside the second push-flattening block 73 and passes through the second push-flattening block 73. The latch rod 78 can limit the push plate 77. A latch limit block 79 that can contact the latch rod 78 is fixedly installed on the printing cavity 11. There are three latch limit blocks 79 in total, two of which are symmetrically arranged on the adjacent sides of the cutting head 72, and the other latch limit block 79 is located in the middle of the positions of the two cutting heads 72.

[0045] The latch rod 78 can be divided into two parts, the front end and the rear end. The front end of the latch rod 78 is designed as a cone, and the rear end of the latch rod 78 is designed as a cylinder. The rear end of the latch rod 78 is close to the middle latch limit block 79, and the push plate 77 is inclined on one side close to the middle latch limit block 79.

[0046] First, when the leather placed on the pushing platform 3 moves with the pushing platform 3 into the printing cavity 11 and is printed with a pattern by the printing nozzle 5, the printed pattern on the leather moves to the bottom of the cutting assembly 7 with the operation of the pushing platform 3, and the main control console unit 2 makes the driving motor work, and the driving motor drives the first reciprocating screw 45 to rotate, and the first reciprocating screw 45 drives the second bevel gear 92 located outside the printing cavity 11 to rotate through the first bevel gear 91, and the second bevel gear 92 located outside the printing cavity 11 drives the rotating rod 93 to rotate, so that the rotating rod 93 drives the second bevel gear 92 located inside the printing cavity 11 to rotate, and the two second bevel gears 92 located inside the printing cavity 11 rotate and drive the two third bevel gears 94 fixedly mounted on the second reciprocating screw 71 to rotate, so that the second reciprocating screw 71 rotates, and the second reciprocating screw 71 will drive the cutting head 72 to rotate, and the leather with the printed part below is cut, and when cutting the printing, the excess parts of the leather printed on both sides do not need to be cut later, thereby improving production efficiency;

[0047] When cutting, in order to facilitate the cutting mechanism to cut the leather, the leather surface and the cut position need to be kept flat to avoid uneven edges of the leather after cutting, which affects the appearance and later processing of the leather. When the second reciprocating screw 71 rotates, the screw sleeve 95 and the L-shaped plate 96 will move on the second reciprocating screw 71, and the second push-flattening block 73 fixedly connected to the L-shaped plate 96 will move with the L-shaped plate 96. When the L-shaped plate 96 moves along the direction of the second reciprocating screw 71, it will move with the second push-flattening block 73. When the second push-flattening block 73 moves toward the printing cavity 11, the cylindrical rear end of the latch limiting block 79 will limit the push-flat plate 77, so that the hinge 76 cannot rotate with the push-flat plate 77 (it should be particularly noted here that the hinge 76 is in a tense state when the latch limits the push-flat plate 77). At this time, the push-flat plate 77 will contact the surface of the leather;

[0048] When the push plate 77 moves toward the inner wall of the printing cavity 11, the wrinkles on the leather surface will be pushed flat toward the two edges of the leather. When the second flattening block 73 moves and approaches the adjacent side of the cutting head 72, the latch rod 78 will contact the latch limit block 79 on the adjacent side of the cutting head 72, so that the front end of the latch rod 78 is inserted into the movable groove 74 by the latch limit block 79. At this time, the push plate 77 contacts the front end of the latch rod 78. Due to the frustum-shaped design of the front end of the latch rod 78, the hinge 76 that pushes the latch rod 78 to the tension state through the latch limit block 79 can make the push plate 77 tilted. At this time, the push plate 77 will rotate at an angle so as not to contact the leather surface. The second reciprocating screw 71 rotates, and the second flattening block 73 and the pushing plate 77 are moved toward the middle latch limit block 79. When the second flattening block 73 moves to the middle latch limit block 79, the rear end of the latch rod 78 will first contact the middle latch limit block 79 and then be squeezed by the middle latch limit block 79. The front end of the latch rod 78 is in the inclined position of the pushing plate 77. As the latch rod 78 moves, the rear end of the latch rod 78 will limit the pushing plate 77 again through the inclined position of the pushing plate 77, so that the hinge 76 is in a tense state, and the pushing plate 77 contacts the leather, which is convenient for continuing to flatten the leather surface next time.

[0049] After the printed leather is cut, the cut part and the retained part move out of the printing cavity 11 along with the pushing table 3, and the cut portion between the cut part and the retained part of the leather will coincide with the cutting groove 31. When contacting the guide block 81, the inclined portion at the bottom of the guide block 81 will contact the cut portion between the cut part and the retained part of the leather, and separate the cut part of the leather from the retained part of the leather. The cut part of the leather will move out along the two sides of the guide block 81 that are inclined and face the pushing table 3, thereby achieving the effect of automatically processing the cut part of the leather after cutting, and the automation is stronger.

[0050] like Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, a drying component 6 for drying the surface of the printed leather is provided inside the printing cavity 11, and the drying component 6 includes a bellows 61 fixedly mounted on the inner wall of the printing cavity 11, an air inlet 62 is provided on the upward portion of one end of the bellows 61 close to the inner wall of the printing cavity 11, and an exhaust port 63 is provided on the downward portion of one end of the bellows 61 close to the inner wall of the printing cavity 11, and a drying pipe 65 is fixedly mounted on the inner wall of the printing cavity 11, and the drying pipe 65 can be used to blow air toward the bottom of the drying pipe 65, and the drying pipe 65 is placed below the bellows 61, and the bellows 61 is connected to the drying pipe 65 through the exhaust port 63, and the outer surface of the exhaust port 63 is provided with a heating plate 64 capable of heating the exhaust port 63.

[0051] A plurality of groups of air jet holes 66 are provided below the drying tube 65 , and the air jet holes 66 are connected to the interior of the drying tube 65 . The heating plate 64 can be controlled by the main console unit 2 .

[0052] When the leather is transported by the push table 3 and moves to the bottom of the drying component 6, since the pattern pigment sprayed by the printing nozzle 5 is not dry at this time, in order to avoid defects in the pattern during cutting, the drying component 6 will work to dry the undried pigment to reduce the occurrence of defects in the pattern. When the second reciprocating screw 71 rotates, the screw sleeve 95 that is spirally driven with the second reciprocating screw 71 will move back and forth on the second reciprocating screw 71 with the L-shaped plate 96 due to the fixing effect of the bellows 61, so that the bellows 61 can inhale air through the air inlet 62 and exhaust air through the exhaust port 63. The bellows 61 pushes the internal gas to the drying tube 65 below through the exhaust port 63, and the gas heated by the heating plate 64 is sprayed from the air jet hole 66 below the drying tube 65 onto the leather with the pattern printed below, thereby drying the pattern on the leather;

[0053] During the process of air intake and air suction of the bellows 61, when the two lead screw sleeves 95 simultaneously move toward the two side walls of the printing chamber 11, the two bellows 61 simultaneously contract, and at this time, the gas inside the bellows 61 is injected into the drying tube 65 through the exhaust port 63. When the second reciprocating lead screw 71 continues to rotate, the two lead screw sleeves 95 simultaneously move toward the center part of the second reciprocating lead screw 71, and the two bellows 61 extend, and the gas heated by the heating plate 64 is sucked into the bellows 61 through the air inlet 62;

[0054] The premise for the implementation of the above technical solution is that the air inlet 62 and the exhaust port 63 on the bellows 61 are both one-way valves. The air inlet direction of the air inlet 62 is from the outside of the bellows 61 to the inside of the bellows 61, and the air outlet direction of the exhaust port 63 is from the inside of the bellows 61 to the inside of the drying tube 65. The heating plate 64 can be controlled by the main console unit 2 to heat the air inlet 62. The air inlet 62 is long enough to heat the gas entering the bellows 61.

[0055] Instructions for use: When the guide assembly 4 is working, the staff first places the leather on the push table 3 with the guide plate 41, and aligns the edge of the leather with the inner wall of the guide plate 41 with the fixed head 43. Then the main console unit 2 controls the drive inside the printing machine body 1 to rotate the first reciprocating screw 45. When the first reciprocating screw 45 rotates, the first flattening block 46 that is spirally driven with the first reciprocating screw 45 will move back and forth on the first reciprocating screw 45. During the back and forth movement of the first flattening block 46, the first flattening block 46 will smooth the surface of the leather. At the same time, when the staff places the leather on the push table 3, the rubber wheel 44 in the fixed head 43 will fix the leather in a line, so as to facilitate the first flattening block 46 to flatten the leather toward the guide plate 41 without the fixed head 43, thereby realizing the function of assisting the staff to place the leather and facilitating the printing function of the printing nozzle 5.

[0056] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
