DETAILED DESCRIPTION

[0040] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0041] Please refer to Figures 1 to 9 , a fur printing equipment provided by the present application will be described. The fur printing equipment comprises a frame body 1 and a printing device 2 arranged on the frame body 1, the printing device 2 comprises a printing screen 21 which is arranged on the frame body 1 and slides along the height direction, the fur printing equipment further comprises a conveying belt 3 and two end limiting pieces 4; the conveying belt 3 is rotationally arranged on the frame body 1; a placing space for placing materials is formed between the conveying belt 3 and the printing screen 21; a feeding port 31 is formed at the position of the conveying belt 3 on one side of the placing space; the two end limiting pieces 4 are arranged at the position of the conveying belt 3 in the placing space, and the end limiting pieces 4 are located at the position of the conveying belt 3 away from the feeding port 31; the two end limiting pieces 4 respectively have oppositely arranged L-shaped limiting cavities for contacting the two corner positions of the materials; wherein, the conveying belt 3 has a sliding groove 32 for sliding connection of the end limiting pieces 4, and the fur printing equipment further comprises a driving structure 5 for driving the end limiting pieces 4 to slide out of or retract into the sliding groove 32; when printing the materials, the end limiting pieces 4 protrude from the sliding groove 32 to limit the materials; after the printing is completed, the materials are conveyed to the discharging end by the conveying belt 3, and the end limiting pieces 4 slide into the sliding groove 32 to separate the materials from the conveying belt 3.

[0042] Compared with the prior art, the fur printing equipment provided by the application has the following advantages: before printing the material, the printing screen 21 is lifted upward to form a placing space between the printing screen 21 and the conveying belt 3; at this time, the operator places the material on the conveying belt 3, and aligns two edges of the material with the L-shaped cavities of the two end limiters 4, so that the material can be positioned without manually adjusting the position of the material; then the printing screen 21 presses the material downward, and the pattern on the printing screen 21 can be printed on the material by the movement of the squeegee 22. Through the above setting, compared with the manual positioning mode of the material, the application can improve the positioning accuracy, and thus ensure the printing quality. The printing device 2 can be multiple, and three printing devices 2 are taken as an example for description in the embodiment.

[0043] It should be noted that the printing device 2 includes a support frame 23 which spans the conveying belt 3, and the support frame 23 is connected between the frame body 1 and the cylinder 24 to enable the support frame 23 to slide up and down; the printing screen 21 is fixed on the support frame 23, and the printing screen 21 can be in contact with or separated from the material by the lifting of the support frame 23. The support frame 23 has a sliding part 25 which slides horizontally, and the squeegee 22 and the ink return knife 26 are arranged on the sliding part 25, and the squeegee 22 and the ink return knife 26 are respectively connected to the sliding part 25 by the cylinder 24; during printing, the squeegee 22 slides downward and is in contact with the printing screen 21, and at this time, the ink return knife 26 is separated from the printing screen 21; then the squeegee 22 slides on the printing screen 21 under the driving of the sliding part 25, and finally the pattern is printed on the material. During ink return, the ink return knife 26 is in contact with the printing screen 21, and the squeegee 22 is separated from the printing screen 21, and the ink return knife 26 is driven to move in the opposite direction by the sliding part 2, so that the ink can be returned to the initial position. The printing device 2 is prior art, and will not be described here.

[0044] In some embodiments, as Figures 1 to 9As shown, the conveying belt 3 has a conveying section 33 and a return section 34, and the driving structure 5 includes a counterweight part 51 and a support plate 52 arranged between the conveying section 33 and the return section 34; the top end of the counterweight part 51 passes through the sliding groove 32 and is connected with the end limiting part 4; the support plate 52 is fixed on the frame body 1, and the top of the support plate 52 is in contact with the bottom of the conveying section 33 to support the conveying section 33 of the conveying belt 3; the support plate 52 is provided with inclined surfaces 521 on both sides along the feeding direction; the pulleys at both ends of the conveying belt 3 are each provided with an annular avoiding groove 35 for avoiding the end limiting part 4; wherein, at the feeding end of the conveying section 33, the inclined surface 521 of the support plate 52 is used to guide the counterweight part 51 to move to the top of the support plate 52, and the end limiting part 4 protrudes out of the sliding groove 32 to limit the material; at the discharging end of the conveying section 33, the counterweight part 51 is separated from the support plate 52, and the end limiting part 4 slides into the sliding groove 32 to separate the end limiting part 4 from the material. By arranging the annular avoiding groove 35 on the pulley, the counterweight part 51 can be located in the annular avoiding groove 35 during the process of the material being separated from the driving belt, thereby reducing the situation that the end limiting part 4 lifts the material.

[0045] It should be noted that before printing the material, the end limiting part 4 is located directly below the printing screen 21, and the counterweight part 51 is in contact with the top of the support plate 52 to lift the end limiting part 4 out of the conveying belt 3; at this time, when the edge and corner positions of the conveying belt 3 are in contact with the end limiting part 4 during the process that the operator places the material on the conveying belt 3, the position of the material can be positioned, and the operator does not need to manually adjust the position of the material, thereby facilitating to improve the positioning accuracy.

[0046] Since the inclined surfaces 521 are arranged on both sides of the support plate 52, when the end limiting part 4 on the conveying belt 3 slides to the printing position, the counterweight part 51 slides upward along the inclined surface 521 and finally contacts the top of the support plate 52; during the above process, the end limiting part 4 slides upward and finally protrudes out of the conveying belt 3, which can play a role in positioning the material. When the conveying belt 3 conveys the material to a position close to the discharging end, no support plate 52 is arranged at this position, so the counterweight part 51 moves downward under the action of gravity, so that the end limiting part 4 slides into the sliding groove 32, and the end limiting part 4 loses the limiting effect on the material, thereby facilitating the material to leave the conveying belt 3 from the discharging end.

[0047] In some embodiments, as shown in Figures 1 to 9 The discharging end of the conveying belt 3 is provided with a connecting plate 6, the connecting plate 6 is arranged obliquely downward away from one side of the conveying belt 3, and a belt conveying structure is arranged at the low end of the connecting plate 6.

[0048] It should be noted that the belt conveying structure at the low end of the connecting plate 6 can be a belt conveyor, which is a prior art and will not be described here. Through the above arrangement, the printed material can be conveniently conveyed to the next process.

[0049] In some embodiments, as shown in Figures 1 to 9 The fur printing device further comprises a side limiting piece 7 for contacting the side of the material, and the conveying belt 3 has a sliding groove 32 that slidingly matches the side limiting piece 7; the bottom of the side limiting piece 7 is also connected with a counterweight part 51.

[0050] It should be noted that the side limiting piece 7 is two, respectively contacting the two sides of the material, which can further improve the limiting ability. The end limiting piece 4 is an L-shaped structure, and the side limiting piece 7 is a strip-shaped structure; the connection relationship between the side limiting piece 7 and the counterweight part 51 is the same as that between the end limiting piece 4 and the counterweight part 51, which will not be described here.

[0051] In some embodiments, as shown in Figures 1 to 9 The bottom of the conveying section 33 opposite to the sliding groove 32 has a slot 36, and the counterweight part 51 is insertedly matched with the slot 36; the counterweight part 51 is connected with the end limiting piece 4 through a connecting rod 53, the diameter of the connecting rod 53 is smaller than that of the counterweight part 51, and the diameter of the connecting rod 53 is smaller than that of the end limiting piece 4; when the end limiting piece 4 protrudes from the sliding groove 32, the height of the protruding part of the end limiting piece 4 is the same as the thickness of the material.

[0052] It should be noted that since the slot 36 is arranged at the bottom of the conveying section 33, when the counterweight part 51 slides to the top of the support plate 52, the counterweight part 51 can be located in the slot 36; through the above arrangement, when the printing screen 21 presses the conveying belt 3 downward, the conveying belt 3 can be in contact with the top of the support plate 52, reducing the situation that the counterweight part 51 blocks the support plate 52 and the conveying belt 3; the flatness of the material can be ensured, thereby ensuring the printing quality.

[0053] Since the diameter of the connecting rod 53 is smaller than that of the end limiting piece 4 and the counterweight part 51, during the rotation of the conveying belt 3, the end limiting piece 4 and the counterweight part 51 can be ensured to remain on the conveying belt 3, avoiding the situation that the end limiting piece 4 is separated from the conveying belt 3. The height of the protruding part of the end limiting piece 4 is the same as the thickness of the material, and when the printing screen 21 presses the material, the printing screen 21 can be in contact with the material, avoiding the situation that the end limiting piece 4 protrudes from the material, and the printing screen 21 cannot be attached to the material.

[0054] In some embodiments, as shown in Figures 1 to 9As shown, an anti-rotation strip 54 is fixedly provided on the outer peripheral wall of the connecting rod 53, and a through hole is provided on the top of the slot 36 for sliding engagement with the anti-rotation strip 54; the counterweight part 51 is provided with an insertion hole for insertion into the connecting rod 53 and the anti-rotation strip 54; the side wall of the counterweight part 51 is provided with a threaded hole communicating with the insertion hole, and a set screw 55 is provided at the threaded hole. The set screw 55 is used to press against the connecting rod 53 to fix the counterweight part 51 and the connecting rod 53. A magnetic attraction structure is provided between the counterweight part 51 and the connecting rod 53.

[0055] It should be noted that by setting an anti-rotation strip 54 on the connecting rod 53, rotation of the connecting rod 53 can be prevented, thereby ensuring that the end limiting member 4 slides into the groove 32. After the insertion hole on the counterweight part 51 is engaged with the connecting rod 53, the connecting rod 53 is tightened by the set screw 55, which can limit the position of the counterweight part 51 and the connecting rod 53, making the counterweight part 51 and the connecting rod 53 a single unit. A permanent magnet is provided in the insertion hole of the counterweight part 51, and the connecting rod 53 is made of iron material, so the counterweight part 51 and the connecting rod 53 can be magnetically attracted together, which can improve the connection strength between the counterweight part 51 and the connecting rod 53.

[0056] In some embodiments, such as Figures 1 to 9 As shown, the frame 1 has a material box 8 on one side of the feeding inlet 31 of the placement space. A top support plate 81 is slidably installed inside the material box 8, and the top support plate 81 is used to lift the material upward. The material box 8 is provided with a lifting structure for driving the top support plate 81 to rise and fall. The side of the material box 8 has a slide rail 82 arranged along the height direction. The lifting structure includes a screw 83, a slider 84, and a drive motor 85. The screw 83 is located outside the material box 8 and rotates with the material box 8. The slider 84 is fixed on the top support plate 81. The slider 84 slides with the slide rail 82 and extends out of the material box 8. The extended part of the slider 84 has a threaded hole that is threaded with the screw 83. The drive motor 85 is fixed on one side of the material box 8, and the output shaft of the drive motor 85 is connected to the bottom of the screw 83 to drive the screw 83 to rotate.

[0057] It should be noted that when stacked materials are placed in the material box 8, after the operator takes out one material, the top support plate 81, driven by the drive motor 85, can rise one material's distance, making it easier for the operator to take out the next material; the above process is repeated until all the materials are taken out of the material box 8. With the above settings, during the forward rotation of the screw 83, the top support plate 81 can slide upward, thereby lifting the material upward; during the reverse rotation of the screw 83, the top support plate 81 can slide downward to the bottom, thereby facilitating the stacking of materials into the material box 8.

[0058] The above merely describes preferred embodiments of the present application, and is not used to limit the present application, any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
