Description

Technical Field

[0001] This utility model belongs to the technical field of tufting machines, specifically relating to an embroidery tufting machine. Background Technology

[0002] The working principle of a tufting machine is to weave yarn onto a base fabric using rollers and a needle punching mechanism to form a fluffy fabric. In the needle punching mechanism above the needle bed, the needles pierce the base fabric at a certain angle and speed, while the rollers retract at a certain speed, weaving the yarn onto the base fabric to form fluff.

[0003] During tufting and embroidery, lint is generated. If not handled promptly, it not only affects the processing environment but also easily enters the processing equipment, potentially disrupting its normal operation. To address this issue, Chinese patent document CN221192577U discloses a nylon carpet tufting machine, including a base with a noodle-shaped groove on its top. Support legs are fixedly connected to the four corners of the base's bottom. An internal collection mechanism is installed within the base. By activating a blower, air is drawn from the collection frame, creating negative pressure. This draws in fresh air through the noodle-shaped groove while simultaneously drawing lint from the top of the base into the collection frame. A filter screen prevents the lint from being re-expelled by the blower.

[0004] However, the collection mechanism of the aforementioned tufting machine can only suck up the pile dust from the bottom surface of the processed carpet, while the pile dust is mainly generated on the surface during processing, resulting in low and insufficient collection efficiency of the pile dust.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6This utility model provides an embroidery tufting machine, including a tufting machine platform 1. A servo moving guide rail 2 is provided on the tufting machine platform 1, and a tufting machine head 3 is mounted on the servo moving guide rail 2. Support frames 4 are mounted on both sides of the tufting machine platform 1, and lifting cylinders 5 are mounted on the support frames 4. A fan hood 6 is fixed to the piston rod end of the lifting cylinder 5. An exhaust device 7 is installed on the tufting machine platform 1, and the exhaust device 7 is connected to the fan hood 6 through a flexible air duct 8. The fan hood 6 faces the center of the tufting machine platform 1, and a filter screen assembly 9 is provided inside the fan hood 6. When performing embroidery tufting, the required... The fabric to be embroidered is placed flat on the tufting machine 1. The distance between the two fan hoods 6 is adjusted so that they are above the edge of the fabric to be processed. Then, the lifting cylinder 5 drives the fan hoods 6 to descend and press down on both sides of the fabric edge. The servo moving guide rail 2 is controlled by the external control panel to move according to the set trajectory, and the tufting machine head 3 tufts and embroiders the set pattern. During this process, the exhaust device 7 is turned on and the fan hoods 6 generate suction through the flexible air duct 8, which in turn draws the lint and dust generated above the fabric during processing into the two fan hoods 6 and blocks them with the filter screen assembly 9. This can achieve efficient treatment of the lint and dust generated during the tufting of the fabric.

[0027] Specifically, the support frame 4 has a top plate 10 on top, a guide groove 11 on top plate 10, an adjusting plate 12 on top plate 10, a guide rail 13 partially located in the guide groove 11 at the bottom of the adjusting plate 12, a fixing plate 14 on the adjusting plate 12, and an adjusting cylinder 15 on top plate 10. The piston rod end of the adjusting cylinder 15 is fixedly connected to the fixing plate 14, and the lifting cylinder 5 is mounted on the adjusting plate 12. In this embodiment, the adjusting cylinder 15 drives the fixing plate 14 to move according to the size of the tufting machine 1, thereby causing the adjusting plate 12 to slide horizontally on the top plate 10 through the cooperation of the guide rail 13 and the guide groove 11, adjusting the distance between the two wind hoods 6 so that they are located above the edge of the fabric to be processed.

[0028] Specifically, the top of the shroud 6 is equipped with a guide rod 16, which passes through the adjusting plate 12. The adjusting plate 12 is slidably connected to the guide rod 16 through an installed linear bearing. In this embodiment, the guide rod 16 and the linear bearing cooperate to position the shroud 6 during its raising and lowering process.

[0029] Specifically, the filter assembly 9 includes a filter frame 17, a first filter 18, and a second filter 19. The hood 6 has a mounting groove inside its opening. The filter frame 17 is fixed in the mounting groove by screws. The first filter 18 and the second filter 19 are respectively located on both sides inside the filter frame 17, with a gap between them. The mesh diameter of the first filter 18 is larger than that of the second filter 19, and the first filter 18 is located on the outside. In this embodiment, the first filter 18 can block lint and prevent it from being sucked into the fan. At the same time, the second filter 19, which has a smaller pore size, further improves the ability to block lint and debris. After processing, the fixing screws can be unscrewed to remove the first filter 18 and the second filter 19 for cleaning of lint and debris.

[0030] Specifically, the hood 6 is provided with a second mounting groove, through which a diversion component 20 is installed. In this embodiment, during the suction of lint, since the hood 6 has a certain length, the suction at the flexible air duct 8 is difficult to fully cover the fabric. By setting the diversion component 20, the airflow will be diverted multiple times when flowing from one side to the other, which is conducive to the uniform suction and coverage of the fabric.

[0031] Specifically, the diversion component 20 includes a diversion frame 21, and the diversion frame 21 is provided with multiple sets of grid plates 22, with multiple grid plates 22 arranged at equal intervals in the same row; in this embodiment, the airflow will be diverted in the gaps between the grid plates 22.

[0032] Specifically, the grid plates 22 are inclined and arranged in multiple rows, with adjacent rows of grid plates 22 having opposite inclination directions, forming multiple rows of first gap channels 23 with wavy directions; in this embodiment, the first gap channels 23 with wavy directions facilitate the continuous change of direction of airflow and facilitate the diversion of airflow at the inflection point.

[0033] Specifically, there is a gap between adjacent rows of grid plates 22, forming a second gap channel 24. In this embodiment, when the airflow flows in the first gap channel 23, it will split along each intersection of the first gap channel 23 and the second gap channel 24. When the airflow flows from one side to the other side, it will split multiple times to achieve uniform adsorption on the other side, thereby achieving uniform suction and coverage of the fabric.

[0034] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0035] Working principle: When embroidering tufting, the fabric to be embroidered is placed flat on the tufting machine table 1. Then, according to the size of the tufting machine table 1, the fixed plate 14 is moved by the adjusting cylinder 15, which in turn moves the adjusting plate 12 horizontally on the top plate 10 through the cooperation of the guide rail 13 and the guide groove 11. The distance between the two fan hoods 6 is adjusted so that they are above the edge of the fabric to be processed. Then, the lifting cylinder 5 moves the fan hoods 6 down to press down the two sides of the fabric edge. The servo moving guide rail 2 is controlled by the external control panel to move according to the set trajectory, and the tufting machine head 3 tufts and embroiders the set pattern. During this process, the exhaust device 7 is turned on to generate suction in the fan hoods 6 through the flexible air duct 8, which sucks the lint generated above the fabric during processing into the two fan hoods 6 and blocks it with the filter screen assembly 9. This can achieve efficient treatment of the lint generated during fabric tufting.

[0036] Since the filter assembly 9 includes a second filter 19 and a first filter 18, the first filter 18 can block lint and prevent it from being sucked into the fan. At the same time, the second filter 19 with a smaller pore size further improves the ability to block lint and debris. After processing, the fixing screws can be unscrewed to remove the first filter 18 and the second filter 19 to clean the lint and debris.

[0037] During the lint suction, since the hood 6 has a certain length, the suction at the flexible air duct 8 is difficult to fully cover the fabric. It is preferable to set multiple spaced flexible air ducts 8 along the length of the hood 6. The connection of the flexible air ducts 8 generates negative pressure suction, which causes airflow to form at the left end of the diversion component 20. Since the grid plate 22 forms the first gap channel 23 and the second gap channel 24, when the airflow flows in the first gap channel 23, diversion will occur at each intersection of the first gap channel 23 and the second gap channel 24. When flowing from one side to the other side, the airflow will be diverted multiple times to achieve uniform adsorption on the other side, thereby achieving uniform suction and coverage of the fabric.

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