Description

Technical Field

[0001] This invention relates to the field of Venetian blind production and processing equipment technology, specifically to a Venetian blind production and processing equipment. Background Technology

[0002] Currently, Venetian blinds typically use manual or electric mechanisms to flip and retract their slats. They have a uniform diameter, with the slats arranged in an orderly fashion. Each slat has a pull cord for flipping the slats, and each slat has a through-hole through which the pull cord is threaded. Traditional Venetian blind manufacturing equipment is relatively simple, only capable of threading the slats through the pull cord or simply threading the slats through the holes. Furthermore, during processing, counting and length cutting of the slats cannot be done in one step, resulting in low production efficiency, inconsistent product quality, and increased production costs.

[0003] Existing technology discloses an automatic slat threading device for Venetian blinds, which can separately perform punching / cutting and ladder rope threading. However, in the common Venetian blind manufacturing process, the aluminum sheet needs to be arc-pressed before being fed into the feeding mechanism. After feeding, it is punched and cut, then transferred to the rope threading process. Finally, a rope winder is installed on the track, and the ladder rope with the blind slats is connected to the rope winder. In this process, the blind slats still need to be processed separately on different equipment. Although existing technologies have achieved partial automation, most of the processing still requires transfer between multiple independent devices, and true full automation cannot be achieved. Therefore, a new structure is urgently needed to solve the defects and deficiencies in the existing technology. Summary of the Invention

[0004] In view of the prior art, the purpose of this invention is to provide a device that can realize the integrated and fully automated production and processing of Venetian blinds from raw materials to finished blinds, so as to solve the problems of transferring slats between multiple independent devices, low production efficiency, excessive manual intervention and unstable finished product quality in the prior art, thereby greatly improving production efficiency, reducing production costs and ensuring the consistency of product quality.

[0015] As a further provision of the above scheme, the pressing wheel includes a convex wheel and a concave wheel arranged according to the shape of the curtain slats. The convex wheel and the concave wheel are abutting each other, and the spacing of the curtain slat shaping channel formed between them is less than or equal to the thickness of the curtain slats.

[0016] As a further provision of the above scheme, the cutting mechanism includes a slitting blade for cutting the curtain slats and a finishing blade for punching holes and trimming the edges of the curtain slats.

[0017] As a further feature of the above solution, the feeder is used to transport the rope winding assemblies one by one, and the track conveying unit is used to transport and feed the window track; the fixture includes several blocks for forming the window track processing station; the spreader is located above the window track processing station and is driven by a spreader cylinder; the spreader is provided in two sets, which are engaged with both sides of the window track based on the action of the spreader cylinder to open the opening above the window track; the gripper unit located between the two sets of spreaders is used to install the rope winding assembly onto the window track; the fixture is equipped with sensors at the corresponding processing station, and the sensors include three sets: A, B, and C; wherein, sets A and C are used to sense the obstruction state of the window track, and set B is located directly opposite the rope hole of the window track to sense the unobstructed state; when sets A, B, and C simultaneously detect the specified state, the spreader is triggered to open the window track for subsequent rope winding assembly installation and processing.

Detailed Implementation

[0028] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0029] like Figure 1-6 The purpose shown is to provide a Venetian blind production and processing equipment, including a slat processing mechanism 1 located on one side of the equipment, a slat threading mechanism 2 in the middle, and a track processing mechanism 3 on the other side.

[0030] The slat processing mechanism 1 includes:

[0031] The raw material supply component 4 includes a raw material reel 42 and a raw material roller 43 for mounting the raw material reel 42. The roller shaft 44 of the raw material roller 43 is provided with a ratchet assembly for realizing unidirectional winding out of the raw material.

[0032] The tablet pressing mechanism 5 is provided with a plurality of tablet pressing wheels 51, positioning wheels 52 and a slat shaping channel 53 composed of the tablet pressing wheels 51 and the positioning wheels 52. The end of the slat shaping channel 53 is also provided with a cutting mechanism 54.

[0033] The track processing mechanism 3 includes:

[0034] The track conveying unit 31, the feeder 32 of the rope winding assembly 8, and the mounting mechanism 7 for mounting the rope winding assembly 8 to the track, the mounting mechanism 7 including a clamp 71 equipped with a sensor, a spreader 72 movable relative to the clamp 71, and a gripper unit 73 for gripping the rope winding assembly 8.

[0035] The slat threading mechanism 2 is located between the slat processing mechanism 1 and the track processing mechanism 3, and is used to receive the window track 92 on which the cord winding assembly 8 is installed and the slats 91 after being pressed and shaped; wherein, the cord winding assembly 8 includes a positioning buckle wheel, a square steel shaft and a cord winder.

[0036] The inserting mechanism 2 also includes:

[0037] Ladder rope supply assembly 6, which includes a rope reel 61, a feeding wheel 62, a tensioning guide wheel 63, a rope clamp 64, and a cutting blade 65;

[0038] The rope clamping claw 67 is located at the upper end of the ladder rope supply assembly 6 and is configured to pass through the rope hole provided on the window rail 92 to pull the ladder rope located below to the rope winding assembly 8 and to wind the end of the ladder rope to the rope winding assembly 8.

[0039] As a further provision of the above scheme, the pressing wheel 51 includes a convex wheel 511 and a concave wheel 512 arranged according to the shape of the curtain blade 91. The convex wheel 511 and the concave wheel 512 are abutted together, and the spacing of the curtain blade shaping channel 53 formed between them is less than or equal to the thickness of the curtain blade 91.

[0040] As a further provision of the above scheme, the cutting mechanism 54 includes a slitting blade 541 for cutting the curtain slats 91 and a finishing blade 542 for punching holes and trimming the edges of the curtain slats 91.

[0041] As a further provision of the above scheme, the feeder 32 is used to transport the rope winding assemblies 8 one by one, and the track conveying unit 31 is used to transport and feed the window rail 92; the clamp 71 includes several stops 711 for forming the processing station of the window rail 92; the spreader 72 is located above the processing station of the window rail 92 and is driven by the spreader cylinder 721; the spreader 72 is provided in two sets, which are engaged with both sides of the window rail 92 based on the action of the spreader cylinder 721, for spreading open the opening above the window rail 92; The gripper unit 73 between the two sets of spreaders 72 is used to install the rope winding assembly 8 onto the window rail 92. The clamp 71 is equipped with sensors at the corresponding processing station. The sensors include three sets: A, B, and C. Among them, sets A and C are used to sense the obstruction state of the window rail 92, and set B is located directly opposite the rope hole of the window rail 92 to sense the unobstructed state. When sets A, B, and C detect the specified state at the same time, the spreader 72 is triggered to open the window rail 92 so that the subsequent installation and processing of the rope winding assembly 8 can be carried out.

[0042] As a further provision of the above scheme, the ladder rope belt is wound around the rope reel 61 and passes sequentially around the feeding wheel 62, the tensioning guide wheel 63 and the rope clamp 64; the rope clamping claw 67 is located above the transmission path of the ladder rope belt and is configured to clamp the ladder rope belt and pull it upward; the ladder rope belt is provided with several through holes formed by horizontal ropes at intervals along its length for the curtain slats 91 to pass through. When the ladder rope belt is pulled open, the position of the through holes corresponds to the transmission path of the curtain slats 91 output by the curtain processing mechanism 1.

[0043] Preferably, the rope clamping claw 67 includes a fixed claw 677 for clamping the traction rope sleeve 675 and a movable claw 678 for clamping the traction rope 676. The rope clamping claw 67 is driven downward by the rope clamping cylinder 671, passes through the rope hole on the window rail 92, clamps the ladder rope belt located below the window rail 92, and pulls it to the upper end of the window rail 92 to connect to the rope winding assembly 8. As described above, the rope clamping claw 67 in this embodiment is used to clamp the ladder rope belt from below the window rail 92 to the upper end, and through the cooperation of the movable claw 678 and the fixed claw 677, the fixed claw 677 clamps the rope belt. While taking it out, the traction rope sleeve 675 is clamped by locking it onto the positioning buckle wheel of the rope winding assembly 8, and the traction rope 676 is clamped from the middle of the traction rope sleeve 675 by the movable claw 678. The traction rope 676 is continuously pulled out and connected to the rope winder of the rope winding assembly 8 by the transverse cylinder 672, connecting the ladder rope belt to the window rail 92. After the rope clamping claw 67 is released, the end of the traction rope sleeve 675 of the ladder rope belt is fixed on the positioning buckle wheel, and the traction rope 676 is connected to the winding wheel of the rope winder. The threading mechanism 2 can also be equipped with a rotating mechanism to make it continuously wind the traction rope 676.

[0044] Working principle:

[0045] After the equipment is started, the tableting mechanism 5 extracts the raw material from the raw material supply component 4. Under the constraint of the raw material roller 43, the raw material reel 42 of the raw material supply component 4 smoothly conveys the raw material of the curtain blade 91 to the tableting mechanism 5.

[0046] The raw material enters the slat shaping channel 53, which is formed by the contact of convex rollers 511 and concave rollers 512. Through the continuous rolling of several sets of pressing rollers 51 and positioning rollers 52, it is gradually pressed into the shape of the slat 91 that meets the design requirements. The end size and shape of the slat shaping channel 53 ensures the final state of the slat 91.

[0047] Once the shaped slats 91 are conveyed to the next mechanism and their dimensions reach the preset size, the cutting mechanism 54 starts working. The slitting blade 541 cuts the continuous slats 91 into individual pieces of the required length, while the straightening blade 542 is used to punch holes (for threading ladder ropes) or trim the edges of the slats 91 with design requirements. The completed slats 91 are then conveyed to the threading mechanism 2 for the next processing step.

[0048] In this embodiment, the track processing mechanism 3 and the tablet pressing mechanism 5 are both independently controlled. They are activated after a group of products are unloaded. The track conveying unit 31 transports the window track 92 segment by segment to the processing station of the loading mechanism 7. At this time, several stops 711 on the fixture 71 form a limit, ensuring accurate positioning of the window track 92. Simultaneously, the feeder 32 transports the rope winding assembly 8 one by one into the gripping range of the claw unit 73. When the window track 92 reaches the processing station, the A and C groups of sensors on the fixture 71 are located below the window track 92 to sense the obstruction state of the window track 92 and confirm that the window track 92 is in place. When the B group sensor is aligned with the rope hole position of the window track 92, it triggers the start-up of the spreader 72. The spreader cylinder 721 drives the two sets of spreaders 72 to move down and engage with the opening above the window track 92, thus spreading it open.

[0049] Subsequently, the gripper unit 73, located between the two sets of extenders 72, grabs the rope winding assembly 8 delivered by the feeder 32 and precisely installs it into the preset position within the window track 92. After installation, the gripper unit 73 and extender 72 reset, and the window track 92, having safely completed the rope winding assembly 8, is conveyed to the slat threading mechanism 2, where it merges with the curtain slats 91 and the ladder rope.

[0050] After the window track 92 reaches the threading mechanism 2, the ladder rope supply assembly 6 starts to work. The ladder rope belt on the rope reel 61 is fed out by the feeding wheel 62, and after the ladder rope belt is tensioned by the tensioning guide wheel 63, it is clamped and positioned by the rope clamp 64. The ladder rope is gripped by the clamping claw 67 and extends upward. The upper end of the ladder rope is fixed to the winding assembly 8 by the clamping claw 67. Based on the fixation at the upper end and the cooperation of the lower clamping device 64, the ladder rope is stretched, so that the ladder rope can be unfolded to facilitate the installation of the first slat 91. The slat perforation in the middle of the unfolded ladder rope is exactly aligned with the slat 91 delivered by the slat processing mechanism 1. After the first slat 91 is delivered, it extends into the slat perforation through the ladder rope to form a combination of slat 91 and ladder rope. Then, the slat threading mechanism 2 retracts the assembled slat 91 upward. The pressing mechanism 5 continues to deliver the subsequent slats 91 into the slat perforations corresponding to the second and subsequent ladder ropes. The pressing mechanism 5 and the slat threading mechanism 2 work together to cyclically thread the slats. During this process, the ladder rope supply assembly 6 continuously supplies the ladder rope.

[0051] Furthermore, when the rope clamping claw 67 of the present invention is started, the fixed claw 677 and the movable claw 678, which have relatively sharp front end structures, extend downwards, pass through the two rope holes on the window rail 92, and continue downwards until they reach the rope clamp 64 of the ladder rope supply assembly 6. After reaching it, the fixed claw 677 clamps the traction rope sleeve 675 of the ladder rope belt, and the movable claw 678 also clamps the movable traction rope 676 inside the traction rope sleeve 675. Subsequently, the rope clamping claw 67 moves upward as a whole, exits the rope hole on the window rail 92, and pulls the lower ladder rope belt above the window rail 92. After reaching the height, the fixed claw 677 rotates along the rope winding assembly 8, and winds and clamps the end of the ladder rope with the rope winding assembly 8 to achieve the fixation of the ladder rope and the rope winding assembly. The movable claw 678, based on the transverse cylinder 672, stretches the traction rope 676 to the rope winding assembly located in the middle, and is driven to rotate a set number of turns by the locking motor that rotates the rope winding assembly. It is worth noting that in this embodiment, the connection between the ladder rope and the rope winding assembly 8 can be achieved using existing technologies, such as by clamping and tightening the rope end through the pre-reserved slot on the rope winding assembly 8.

[0052] The equipment of this invention also needs to be used in conjunction with a finished product unloading and track pre-processing mechanism to unload the semi-finished curtains processed by the equipment of this invention. After all the curtain slats of a set are installed and threaded, the cutting blade 65 cuts the ladder rope. Through the coordinated operation of the curtain slat processing mechanism 1, the slat threading mechanism 2 and the track processing mechanism 3, the integrated production process of the Venetian blinds from raw material processing to window track assembly and curtain slat threading is completed. At this time, the curtain also needs to install a lower beam at the end of the ladder rope that was cut by the cutting blade 65 according to the design requirements, and the normal roll-out and storage state of the Venetian blinds is tested and adjusted by the rope assembly 8.

[0053] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
