Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of three-dimensional fabric production, in particular to a 3D fabric production device and process. BACKGROUND

[0002] Foaming printing, also known as three-dimensional printing, is developed on the basis of paste printing technology. Its principle is to add several chemical substances with high expansion coefficient to the paste printing dye. After drying, the printed part is foamed at a high temperature of 200-300 degrees to achieve a three-dimensional effect similar to "relief". The foaming printing process can produce high, medium and low foaming effects according to the requirements of the printing object. The biggest advantage of foaming printing is that it has strong three-dimensional effect and the printed surface is prominent and expanded. It is widely used on cotton, nylon and other materials.

[0003] Foaming printing paste has developed into two series of physical foaming paste and chemical foaming paste. Physical foaming paste mainly contains microcapsule preparations. Low-boiling-point organic solvents are stored in the microcapsule preparations. When the temperature rises, the organic solvents in the microcapsule preparations rapidly vaporize, causing the microcapsules to swell and press against each other, resulting in irregular overlapping distribution. Therefore, the surface is uneven, so it is also called raising printing. Chemical foaming paste has two types: one is a color paste composed of thermoplastic resin and foaming agent, and the other is a color paste composed of polyurethane and solvent thickener. However, the solvent in the color paste on the fabric needs to be recovered, which brings certain difficulty to the printing factory. Generally, the former is used.

[0004] In the production of three-dimensional fabric, the fabric is usually printed by hand. Finally, a three-dimensional pattern is presented on the fabric. When printing by hand, the printing plate needs to be placed on the fabric, and then the foaming paste is brushed onto the hollow part of the printing plate. If a large number of products are produced, manual printing is not only inefficient, but also the position of the scraper held by the hand may be incorrect during the long brushing process, causing the scraper to deviate, resulting in uneven brushing. Therefore, it is necessary to provide a 3D fabric production device and process to solve the above problems. SUMMARY

[0037] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be further described in detail below in conjunction with the drawings and specific embodiments.

[0038] Reference Figures 1 to 12 The 3D fabric production equipment shown includes a fabric conveying table 1 on which the fabric to be printed is laid flat, and a printing device that spans the fabric conveying table 1 and is used to print the fabric below in three dimensions. The printing device includes an engraved steel plate 2, a steel plate fixing seat, a paste brushing mechanism, and a lifting mechanism. The steel plate fixing seat is provided above the fabric conveying table 1, the engraved steel plate 2 is detachably provided in the steel plate fixing seat, and the lifting mechanism is provided below the steel plate fixing seat. The lifting mechanism is used to lift the steel plate fixing seat, so that the bottom surface of the engraved steel plate 2 is in close contact with the top surface of the fabric. The paste brushing assembly is provided on the steel plate fixing seat and is used to evenly brush the foaming paste sprayed on one end of the engraved steel plate 2 onto the hollow part of the engraved steel plate 2, so that the foaming paste is printed on the fabric through the hollow part of the engraved steel plate 2. The paste brushing assembly includes a paste brushing scraper 3, a reciprocating displacement mechanism, and two sets of deflection mechanisms. The reciprocating displacement mechanism is used to drive the paste brushing scraper 3 to reciprocally horizontally displace on the top of the engraved steel plate 2. Each set of deflection mechanisms is provided at both ends of the paste brushing scraper 3 and includes a lifting vertical plate 4, a limiting piece, a lifting mechanism, and a turning mechanism. The paste brushing scraper 3 is hinged between the two lifting vertical plates 4. The paste brushing scraper 3 is kept in an inclined state by the limiting piece to brush the foaming paste on the engraved steel plate 2. After each brushing, the lifting mechanism lifts the paste brushing scraper 3 by lifting the two lifting vertical plates 4, and the paste brushing scraper 3 is turned over by the turning mechanism when it is lifted.

[0039] The fabric to be processed is laid flat on the fabric conveying table 1, and the fabric can be transported horizontally by winding and unwinding. The horizontal transportation of the fabric is intermittent, that is, the fabric stops displacing when the printing device prints the fabric. In this way, the entire fabric can be printed by the printing device. After printing, a plurality of equidistantly distributed printed patterns will appear on the fabric. In actual production, a high-temperature heating device (prior art, not shown in the figure) is provided downstream of the printing device on the fabric conveying table 1. The printed patterns on the fabric are heated by the high-temperature heating device. Since the raw material of the printed patterns is foaming paste, the foaming paste will expand when heated. Finally, a plurality of equidistantly distributed three-dimensional printed patterns will appear on the fabric. After the printing stage is completed, the wound fabric can be transported to the next process for subsequent processing;

[0040] In the process of printing as follows: when the fabric transport, the steel plate fixed seat is driven by the lifting mechanism to be in the rising state, at this time the fabric displacement towards the lower part of the steel plate fixed seat, when the fabric stop displacement, the fabric stop in the lower part of the steel plate fixed seat, after the lifting mechanism will drive the steel plate fixed seat down, until the bottom of the engraved steel plate 2 on the steel plate fixed seat and the top of the fabric are in contact, then the brush paste assembly will be injected on the end of the engraved steel plate 2 on the foaming paste evenly brush on the engraved steel plate 2 on the hollow part, so that the foaming paste will be printed on the fabric through the hollow part of the engraved steel plate 2, wherein, the upper part of the steel plate fixed seat is provided with a plurality of nozzles (prior art, not shown in the figure), the nozzle is used for intermittent injection of foaming paste on one end of the engraved steel plate 2, the brush paste assembly in the process of brushing the foaming paste, the brush scraping knife 3 in the process of foaming paste is scraped once for one round of brushing, each time the printing brush scraping knife 3 will brush the foaming paste two rounds, that is, the brush scraping knife 3 back and forth displacement once after completing a printing, before the first displacement of the brush scraping knife 3, the above-mentioned nozzle will inject the foaming paste on one end of the engraved steel plate 2, then when the reciprocating displacement mechanism drives the brush scraping knife 3 to displace, the brush scraping knife 3 will scrape the foaming paste on the hollow part of the engraved steel plate 2 along the way, when the brush scraping knife 3 first displacement ends, the side of the brush scraping knife 3 in contact with the foaming paste will still remain a part of the foaming paste which does not penetrate the engraved steel plate 2, at this time the lifting mechanism will drive the brush scraping knife 3 to lift through the two lifting vertical plates 4, so that the brush scraping knife 3 and the engraved steel plate 2 are gradually separated, and when the brush scraping knife 3 is lifted, the brush scraping knife 3 is turned over through the turning mechanism, then when the brush scraping knife 3 is reversely displaced, the brush scraping knife 3 which is again in the inclined state will scrape the foaming paste which is first retained on the hollow part of the engraved steel plate 2 again, so that through the back and forth displacement of the brush scraping knife 3, it is ensured that the hollow part of the engraved steel plate 2 is filled with foaming paste, when the brush scraping knife 3 back and forth displacement once, the lifting mechanism drives the steel plate fixed seat to rise again, then the fabric continues to transport, until the fabric stops displacement again, and the subsequent fabric is printed through the printing device, so as to circulate repeatedly, finally a plurality of equal interval respectively and complete pattern printing on the fabric will be produced;

[0041] The three-dimensional effect of printing is affected by the thickness of the engraved steel plate 2, that is, the thicker the engraved steel plate 2, the better the three-dimensional effect of printing, so in the actual production process, a plurality of engraved steel plates 2 with different thicknesses and different engraved patterns can be prepared, so that different engraved steel plates 2 can be replaced according to production needs.

[0042] In order to show the specific structure of the steel plate fixed seat, the following features are provided:

[0043] The steel plate fixing seat comprises a rectangular base frame 5, two strip-shaped plates 6 and four rotating fasteners. The rectangular base frame 5 is composed of two horizontal plates 7 and two vertical plates 8, the two vertical plates 8 are in parallel, each horizontal plate 7 is arranged between the two vertical plates 8, and the two ends of each horizontal plate 7 are fixedly connected with the two vertical plates 8 respectively, the two strip-shaped plates 6 are fixedly arranged on the top of the two horizontal plates 7 respectively, the engraved steel plate 2 is horizontally placed on the two strip-shaped plates 6, the two ends of each strip-shaped plate 6 are formed with a horizontal supporting plate 9, each supporting plate 9 is located directly above one end of the corresponding strip-shaped plate 6, and the four rotating fasteners are arranged on the four supporting plates 9 respectively. Each rotating fastener comprises a threaded sleeve 10 and a fastening bolt 11. The threaded sleeve 10 is fixedly arranged on the top of the corresponding supporting plate 9 in a vertical state, the fastening bolt 11 is rotatably arranged in the corresponding threaded sleeve 10, the lower end of the fastening bolt 11 sequentially penetrates the threaded sleeve 10 and the supporting plate 9 downwards, and the lower end of the fastening bolt 11 is coaxially fixedly connected with a pressing plate 12 for pressing the corresponding end corner of the engraved steel plate 2. Among them, the two horizontal plates 7 are provided with a groove 13 for the engraved steel plate 2 to be downwardly attached to the fabric, and the lifting mechanism comprises four lifting cylinders 53 arranged in a matrix under the rectangular base frame 5, and the four lifting cylinders 53 are arranged in pairs and correspond to the two ends of the horizontal plate 7.

[0044] When the engraved steel plate 2 is installed, first, each fastening bolt 11 is rotated to displace the corresponding pressing plate 12 upwards, then the horizontal engraved steel plate 2 is placed on the two strip-shaped plates 6, at this time, the two ends of the engraved steel plate 2 correspond to the two strip-shaped plates 6 respectively, and the four end corners of the engraved steel plate 2 correspond to the four pressing plates 12 respectively, and finally each fastening bolt 11 is rotated to displace the corresponding pressing plate 12 downwards. In this process, the pressing plate 12 will abut against the corresponding end corner of the engraved steel plate 2, and the four end corners of the engraved steel plate 2 are pressed tightly against the strip-shaped plates 6, so as to finally fix the engraved steel plate 2. When it is necessary to replace the engraved steel plate 2 with different thicknesses subsequently, each fastening bolt 11 is loosened, and the current engraved steel plate 2 can be removed.

[0045] After the installation of the engraved steel plate 2, the groove 13 arranged between the two horizontal plates 7 enables the bottom of the engraved steel plate 2 to be attached to the top of the fabric when the steel plate fixing seat is lowered.

[0046] The four lifting cylinders move synchronously to drive the entire rectangular base frame to rise and fall.

[0047] In order to realize the positioning of the engraved steel plate 2 and ensure that the hollow part on the engraved steel plate 2 is directly opposite the central part of the fabric after installation, the following features are specifically provided:

[0048] The steel plate fixing seat is provided with a steel plate positioning mechanism. The steel plate positioning mechanism comprises a threaded rod 14 and two groups of sliding contact elements. The threaded rod 14 is horizontally rotatably arranged on the outer side of one of the vertical plates 8. Each group of sliding contact elements comprises a sliding sleeve 15 and a push strip 16. Each sliding sleeve 15 is sleeved on the threaded rod 14. The threaded rod 14 is provided with two sections of threads with opposite rotation directions. Two sliding sleeves 15 are respectively provided with thread grooves in threaded cooperation with the two sections of threads. Each sliding sleeve 15 is slidably connected with the corresponding vertical plate 8 along the axial direction of the threaded rod 14. Two push strips 16 are respectively located on the sides of the two strip-shaped plates 6. Each push strip 16 is fixedly connected with the corresponding sliding sleeve 15 through a horizontal connecting rod 17. A plurality of contact strips 18 for contacting one end of the engraved steel plate 2 are formed on each push strip 16. One end of the threaded rod 14 is coaxially fixedly connected with a rotating cap 19.

[0049] When the engraved steel plate 2 is processed, the hollow part thereon is located at the center of the whole engraved steel plate 2. Therefore, when the engraved steel plate 2 is fixed, the position of the engraved steel plate 2 cannot be ensured to be correct by the naked eye. Therefore, the steel plate positioning mechanism of the device can position the engraved steel plate 2 before the engraved steel plate 2 is fixed. The specific positioning process is as follows: after the engraved steel plate 2 is placed on the two strip-shaped plates 6, the threaded rod 14 is rotated by rotating the rotating cap 19. After the threaded rod 14 is rotated, the two sliding sleeves 15 will be displaced towards each other. In this way, the two sliding sleeves 15 will drive the two push strips 16 to be displaced towards each other through the corresponding horizontal connecting rods 17 in the displacement process. During the displacement of the two push strips 16, the plurality of contact strips 18 provided on each push strip 16 will contact one end of the engraved steel plate 2. In this way, the engraved steel plate 2 will gradually correct the position until the two push strips 16 tightly contact the engraved steel plate 2. At this time, the hollow part on the engraved steel plate 2 will be opposite to the center of the fabric. Then, the four end corners of the engraved steel plate 2 can be fixed by the four rotating fasteners.

[0050] When the engraved steel plate 2 is installed, the above-mentioned steel plate positioning mechanism can position the engraved steel plate 2, so that the hollow part on the engraved steel plate is opposite to the center of the fabric. However, when the engraved steel plate 2 is placed on the two strip-shaped plates 6, the engraved steel plate 2 may be left-right offset, which finally leads to different distances between adjacent two printed patterns after printing. Therefore, a limiting strip 54 for limiting the left-right offset of the engraved steel plate 2 is processed on each strip-shaped plate 6.

[0051] In order to show the specific structure of the reciprocating displacement mechanism, the following features are provided:

[0052] The top of each vertical plate 8 is shaped as a horizontal supporting plate 20, the reciprocating displacement mechanism comprises two electric sliding rails 21 and two sliding blocks 22, each electric sliding rail 21 is fixed on the corresponding supporting plate 20 in a horizontal state, each sliding block 22 slides on the corresponding electric sliding rail 21, each sliding block 22 is fixed with an L-shaped support 23, the brush scraping knife 3 is arranged between the two L-shaped supports 23, the horizontal end of each L-shaped support 23 faces the brush scraping knife 3, each lifting mechanism comprises a lifting block 24 which is connected with the horizontal end of the L-shaped support 23 in a sliding manner in the vertical direction, and each lifting block 24 is fixedly connected with the corresponding lifting vertical plate 4.

[0053] The two sliding blocks 22 are synchronously displaced on the two electric sliding rails 21, the displacement of the two sliding blocks 22 drives the corresponding L-shaped supports 23 to displace, so that after the displacement of the two L-shaped supports 23, each L-shaped support 23 drives the corresponding lifting vertical plate 4 to displace horizontally through the lifting block 24, and finally the two synchronously displaced lifting vertical plates 4 drive the whole brush scraping knife 3 to displace horizontally.

[0054] The displacement stroke of the sliding block 22 is controlled by an upper computer (not shown in the figure), and the sliding block 22 stops after moving back and forth on the corresponding electric sliding rail 21 once.

[0055] In order to show the specific structure of the lifting mechanism, the following features are provided:

[0056] Each lifting mechanism further comprises two first abutting frames 25 and two second abutting frames 26, the horizontal end of each L-shaped support 23 is fixed with two symmetrical guide sliding shafts 27, each lifting block 24 is provided with two guide sliding grooves corresponding to the two guide sliding shafts 27, each lifting block 24 slides on the two guide sliding shafts 27 through the two guide sliding grooves, the lower end of each guide sliding shaft 27 is fixed with a first limiting nut 28 for limiting the downward stroke of the lifting block 24, a first spring 29 is sleeved on each guide sliding shaft 27, the upper and lower ends of each first spring 29 abut against the horizontal end of the L-shaped support 23 and the lifting block 24 respectively, wherein a first inclined wedge block 30 is formed on the side surface of each lifting block 24, a second inclined wedge block 31 is formed on each first inclined wedge block 30, the inclined wedge surfaces of the first inclined wedge block 30 and the second inclined wedge block 31 face opposite directions, the two first abutting frames 25 and the two second abutting frames 26 are located above the four rotating fasteners, each first abutting frame 25 and second abutting frame 26 is fixed on the two ends of the corresponding vertical plate 8, the end of each first abutting frame 25 is shaped as a first inclined surface end 32 which abuts with the first inclined wedge block 30, and the end of each second abutting frame 26 is shaped as a second inclined surface end 33 which abuts with the second inclined wedge block 31.

[0057] When the brush blade 3 is displaced between the first abutment 25 and the second abutment 26 by the two sliders 22, each first spring 29 releases the elastic force, so that each lifting block 24 is in a lowered state by the abutment of the corresponding spring, and the lowering stroke of the lifting block 24 is limited by the first limiting nut 28 arranged on the guide shaft 27, so that the brush blade 3 is driven by the two lifting blocks 24 to be in a lowered state, and when the lifting block 24 is at the lowest point of the lowering, the brush blade 3 is in contact with the top of the engraved steel plate 2 to displace, so that the brush blade 3 brushes the foaming paste on the engraved steel plate 2 to the hollow part on the engraved steel plate 2, and when the brush blade 3 is displaced to near the second abutment 26, each second abutment 26 abuts the second inclined wedge block 31 on the corresponding lifting block 24 through the second inclined end 33, and drives the second inclined wedge block 31 to move upward through the inclined wedge cooperation, so that the entire lifting block 24 is driven to move upward, and each first spring 29 is compressed by the upward movement of the lifting block 24, so that the two lifting blocks 24 drive the brush blade 3 to lift, and then the brush blade 3 is immediately reversed after turning over, and during the reverse displacement of the brush blade 3, the second inclined wedge block 31 gradually moves away from the second abutment 26, so that during the process that the second inclined wedge block 31 gradually moves away from the second abutment 26, the compressed first spring 29 gradually releases the elastic force to press the lifting block 24 downward, and after the lifting block 24 is pressed downward, the turned-over brush blade 3 is again in contact with the top of the engraved steel plate 2, and then the reversed brush blade 3 gradually approaches the first abutment 25, and when the first abutment 25 is contacted, the first abutment 25 abuts the first inclined wedge block 30 through the first inclined end 32, and the first inclined wedge block 30 moves upward, so that the lifting block 24 finally drives the brush blade 3 to move upward, and the brush blade 3 turns over again when moving upward, and then each slider 22 stops after moving back and forth once, so that when the subsequent slider 22 moves again, the brush blade 3 will again be lowered and in contact with the top of the engraved steel plate 2 to brush the foaming paste on the hollow part on the engraved steel plate 2.

[0058] In order to show how the brush blade 3 maintains an inclined state to brush the foaming paste, the following features are specifically provided:

[0059] The handle of the slurry scraper 3 has two symmetrically arranged rotating shafts 34. Each lifting plate 4 has a through groove 35, in which a bearing 36 is embedded. Each rotating shaft 34 passes horizontally through the corresponding bearing 36. Each limiting component includes a strip-shaped rotating handle 37 and a tension spring 38. One end of the strip-shaped rotating handle 37 is fixedly connected to the protruding end of the corresponding rotating shaft 34. The length direction of the strip-shaped rotating handle 37 is consistent with the width direction of the slurry scraper 3. On one side of each lifting plate 4 with the strip-shaped rotating handle 37, two shafts 34 are formed around the corresponding rotating shafts 34. 4. The limiting bosses 39 are symmetrical. Below the two limiting bosses 39, there is a first fixing pin 40 located directly below the corresponding rotating shaft 34. A second fixing pin 41 is fixed on the movable end of each strip-shaped rotating handle 37. The axes of the first fixing pin 40 and the second fixing pin 41 are parallel to the axis of the corresponding rotating shaft 34. The tension spring 38 is located on the side of the corresponding lifting plate 4. Both ends of the tension spring 38 are hooked on the first fixing pin 40 and the second fixing pin 41 respectively. Each strip-shaped rotating handle 37 is mounted on one of the limiting bosses 39.

[0060] Since each strip-shaped handle 37 is connected to a corresponding shaft 34, when the strip-shaped handle 37 rotates, the slurry scraper 3 will also rotate. Figure 9 As shown, the movable end of the strip-shaped rotating handle 37 is driven by the tension spring 38 to abut against one of the limiting bosses 39. At this time, the strip-shaped rotating handle 37 is in an inclined state, and the same applies to the slurry scraper 3. When the slurry scraper 3 moves against the engraved steel plate 2, the slurry scraper 3 will generate friction during the movement. This friction will cause the slurry scraper 3 to rotate to one side. However, at this time, the strip-shaped rotating handle 37 is driven by the corresponding tension spring 38 to always abut against one of the limiting bosses 39. At this time, the slurry scraper 3 will always maintain the current inclined state during the process of brushing the foaming slurry. In this way, the inclined slurry scraper 3 can simulate manual brushing and improve the uniformity of the foaming slurry.

[0061] After the lifting plate 4 rises, the entire brushing scraper 3 will be flipped through the flipping mechanism. During this process, each strip-shaped rotating handle 37 will turn from the current limiting boss 39 to another limiting boss 39. During the rotation of the strip-shaped rotating handle 37, the tension spring 38 will be stretched. When the strip-shaped rotating handle 37 is vertical, the stretched tension spring 38 will instantly pull the strip-shaped rotating handle 37 toward the other limiting boss 39. After that, the movable end of the strip-shaped rotating handle 37 will abut against the other limiting boss 39. Thus, after each flipping, the brushing scraper 3 will remain in an inclined state.

[0062] To demonstrate the specific structure of the flipping mechanism, the following features were set:

[0063] Each turnover mechanism comprises two sets of rotating abutting members, each set of rotating abutting members comprises a fixed strip 42, a downward abutting block 43 and a third abutting frame 44, the horizontal end of each L-shaped support 23 is fixedly provided with a vertically downward connecting plate 45, the lower end of each connecting plate 45 is formed with two symmetrical strip-shaped sliding seats 46, each strip-shaped sliding seat 46 is in a vertical state, each downward abutting block 43 slides in the corresponding strip-shaped sliding seat 46, the lower side of each downward abutting block 43 is provided with an elastic member for driving the upward movement of the downward abutting block 43, the two fixed strips 42 are formed on the corresponding rotating shafts 34, and the two fixed strips 42 correspond to the two downward abutting blocks 43 respectively, in the initial state, the bottoms of the two downward abutting blocks 43 are flush and are located above the rotating shafts 34, the top of one of the downward abutting blocks 43 is higher than the top of the other downward abutting block 43, the top of each downward abutting block 43 is fixedly provided with a third inclined wedge block 47, the inclined wedge surfaces of the two third inclined wedge blocks 47 face opposite directions, the two third abutting frames 44 in each set of rotating abutting members are fixedly connected with the corresponding first abutting frame 25 and second abutting frame 26 respectively, and one end of each of the two third abutting frames 44 in each set of rotating abutting members is formed with a third inclined surface end 48 which is in inclined surface cooperation with the corresponding third inclined wedge block 47.

[0064] In the initial state, each elastic member drives the corresponding downward abutting block 43 to move upward, at this time, the bottoms of the two downward abutting blocks 43 are flush and are located above the corresponding rotating shafts 34, when the brush and paste scraper 3 moves close to the first abutting frame 25 or second abutting frame 26, the corresponding third abutting frame 44 will abut against the corresponding third inclined wedge block 47 through the third inclined surface end 48, at this time, one of the downward abutting blocks 43 will be abutted downward to move, at the same time, the brush and paste scraper 3 is lifted by the lifting mechanism, then in the lifting process of the brush and paste scraper 3, one of the downward abutting blocks 43 moves downward to abut against the corresponding fixed strip 42 on the rotating shaft 34, and the rotating shaft 34 rotates by abutting against the fixed strip 42 downward, so that the whole brush and paste scraper 3 turns over, and after the brush and paste scraper 3 turns over, the brush and paste scraper 3 remains in an inclined state by the limiting member, since the brush and paste scraper moves upward, one of the downward abutting blocks 43 moves downward to abut against the corresponding fixed strip 42, then when the rotating shaft 34 rotates, the other fixed strip 42 will not collide with the corresponding downward abutting block 43 due to rotation, after the brush and paste scraper 3 turns over for the first time, it will immediately move reversely, at this time, in the process that one of the downward abutting blocks 43 separates from the corresponding third abutting frame 44, the downward abutting block 43 in the descending state is reset upward to the initial state by the elastic member.

[0065] In order to show the specific structure of the elastic member, the following features are provided:

[0066] Each elastic member comprises a slide pin 49, a second spring 50, a vertical surface support 51 and a second limiting nut 52. The slide pin 49 is vertically fixed at the bottom of the corresponding lower pressing block 43. The vertical surface support 51 is fixed on the corresponding strip-shaped slide seat 46 and is located below the lower pressing block 43. The lower end of the slide pin 49 vertically penetrates the vertical surface support 51. The second limiting nut 52 is screwed on the penetrating end of the slide pin 49. The second spring 50 is sleeved on the slide pin 49. The upper and lower ends of the second spring 50 are respectively in contact with the lower pressing block 43 and the vertical surface support 51. The second limiting nut 52 is used to limit the upward stroke of the slide pin 49.

[0067] In the initial state, each second spring 50 releases elastic force, which drives the corresponding lower pressing block 43 to move upward. At this time, the bottoms of the two lower pressing blocks 43 are flush. When the lower pressing block 43 is pressed by the third pressing frame 44, the lower pressing block 43 will be displaced downward, and at the same time, the second spring 50 will be compressed. The second spring 50 generates elastic force by compression. When the brush blade 3 reversely displaces and makes the lower pressing block 43 gradually away from the third pressing frame 44, the lower pressing block 43 will be driven upward to reset to the initial state by the elastic force of the second spring 50. The second limiting nut 52 limits the upward stroke of the slide pin 49 by being in contact with the vertical surface support 51.

[0068] The production process of the 3D fabric comprises the following steps:

[0069] S1, the fabric to be printed is laid on the fabric conveying table 1;

[0070] The fabric to be processed is laid on the fabric conveying table 1. The fabric can be transported horizontally by winding and unwinding. The horizontal transportation of the fabric is intermittent, that is, the fabric stops moving when the printing device prints the fabric. In this way, the entire fabric can be printed by the printing device. After that, the fabric will have several equidistantly distributed printed patterns.

[0071] S2, the lifting mechanism drives the steel plate fixing seat to rise, and according to the current production requirement, the engraved steel plate 2 with a specific thickness and a printing pattern is fixed on the steel plate fixing seat;

[0072] When the engraved steel plate 2 is installed, first rotate each fastening bolt 11 to make the corresponding pressing piece 12 move upward, then place the engraved steel plate 2 horizontally on the two strip-shaped plates 6, at this time the two ends of the engraved steel plate 2 correspond to the two strip-shaped plates 6 respectively, and the four corners of the engraved steel plate 2 correspond to the four pressing pieces 12 respectively, finally rotate each fastening bolt 11 to make the corresponding pressing piece 12 move downward, in this process the pressing piece 12 will touch the corresponding corner of the engraved steel plate 2, and thus the four corners of the engraved steel plate 2 are pressed tightly with the strip-shaped plates 6, finally the fixation of the engraved steel plate 2 is realized, then when the engraved steel plate 2 with different thickness needs to be replaced, rotate each fastening bolt 11, then the current engraved steel plate 2 can be removed.

[0073] When the engraved steel plate 2 is processed, the hollow part on the engraved steel plate 2 is at the center of the whole engraved steel plate 2, then when the engraved steel plate 2 is fixed, the position of the engraved steel plate 2 cannot be ensured to be opposite to the center of the fabric by the naked eye, so the steel plate positioning mechanism of the device can position the engraved steel plate 2 before the engraved steel plate 2 is fixed, and the specific positioning process is as follows: when the engraved steel plate 2 is placed on the two strip-shaped plates 6, rotate the threaded rod 14 by the cap 19, when the threaded rod 14 rotates, the two sliding sleeves 15 will move towards each other, and thus the two sliding sleeves 15 will drive the two push strips 16 to move towards each other through the corresponding horizontal connecting rods 17 in the process of displacement, in the process of displacement of the two push strips 16, the plurality of touching strips 18 arranged on each push strip 16 will touch one end of the engraved steel plate 2, and thus the engraved steel plate 2 will gradually correct the position until the two push strips 16 tightly abut against the engraved steel plate 2, at this time the hollow part on the engraved steel plate 2 will be opposite to the center of the fabric, then the four rotating fasteners can be used to fix the four corners of the engraved steel plate 2.

[0074] S3, the fabric stops transporting, the lifting mechanism drives the steel plate fixing seat to descend, and the bottom of the engraved steel plate 2 is attached to the top of the fabric;

[0075] After the engraved steel plate 2 is installed, the groove 13 arranged between the two horizontal plates 7 makes the bottom of the engraved steel plate 2 able to be attached to the top of the fabric when the steel plate fixing seat descends.

[0076] S4, the foaming paste on the engraved steel plate 2 is evenly brushed on the hollow part of the engraved steel plate 2 by the paste brushing mechanism;

[0077] The brush slurry assembly is in an inclined state during the process of brushing the foaming slurry, and the brush slurry doctor blade 3 is linearly scraped on the foaming slurry once to be one round of brushing. The brush slurry doctor blade 3 is scraped on the foaming slurry twice each time, that is, the brush slurry doctor blade 3 completes one printing after one-way displacement. Before the first displacement of the brush slurry doctor blade 3, the nozzle sprays the foaming slurry on one end of the engraved steel plate 2. When the reciprocating displacement mechanism drives the brush slurry doctor blade 3 to displace, the brush slurry doctor blade 3 scrapes the foaming slurry on the hollow part of the engraved steel plate 2. When the first displacement of the brush slurry doctor blade 3 is completed, the side of the brush slurry doctor blade 3 in contact with the foaming slurry still retains a part of the foaming slurry that does not penetrate the engraved steel plate 2. At this time, the lifting mechanism drives the brush slurry doctor blade 3 to lift through the two lifting vertical plates 4, so that the brush slurry doctor blade 3 gradually separates from the engraved steel plate 2. When the brush slurry doctor blade 3 is lifted, the brush slurry doctor blade 3 is turned over through the turning mechanism. When the brush slurry doctor blade 3 is displaced in the opposite direction, the brush slurry doctor blade 3 in the inclined state again scrapes the foaming slurry retained for the first time on the hollow part of the engraved steel plate 2. In this way, through the back-and-forth displacement of the brush slurry doctor blade 3, it is ensured that the hollow part on the engraved steel plate 2 is filled with foaming slurry. When the brush slurry doctor blade 3 is displaced back and forth once, the lifting mechanism drives the steel plate fixing seat to rise again. Thereafter, the fabric continues to be transported until the fabric stops again, and the subsequent fabric is printed through the printing device. In this way, the cycle is repeated, and finally a plurality of equally spaced and complete pattern printed patterns are formed on the fabric.

[0078] S5, after the lifting mechanism drives the steel plate fixing seat to rise, the fabric starts to be transported. Thereafter, the above S3 step is repeated.

[0079] In the actual production process, the fabric transportation table 1 is provided with a high-temperature heating device (prior art, not shown in the figure) located downstream of the printing device. The printed pattern on the fabric is heated through the high-temperature heating device. Since the raw material of the printed pattern is foaming slurry, the foaming slurry will expand when the printed pattern is heated. Finally, a plurality of equally spaced three-dimensional printed patterns will be formed on the fabric. After the printing stage is completed, the rolled fabric can be transported to the next process for subsequent processing.

[0080] The above embodiments only express one or several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of protection of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
