Description

Technical Field

[0001] The invention relates to the technical field of blinding processing equipment, in particular to a blinding machine. Background Art

[0002] A large number of round screen flower cylinders are needed for printing. The round screen flower cylinder is composed of two blind heads and round screens connected to the blind heads on both sides. When making a round screen flower cylinder, the round screen is made first, and then the blind heads are installed on both ends of the round screen and connected by glue. The installation of the blind heads is generally carried out by a blind head machine, which is more efficient.

[0003] At present, the blind head machine usually includes a frame, blind head chucks are arranged at both ends of the frame, and a round net bracket is arranged between the blind head chucks. When working, the blind head needs to be fixed on the blind head chuck, so that the round net is fixed on the round net bracket, and then glue is applied to the connection between the blind head and the round net. Usually, a heating device is also arranged on the blind head chuck. The heating device is generally an electric heating wire, which can heat the connection between the blind head and the round net, accelerate the solidification of the glue, and combine the blind head with the round net to form a round net flower tube.

[0004] The existing blind head chuck usually adopts a three-jaw chuck, and its structure mainly consists of a chuck body, three clamping claws and a driving mechanism. The driving mechanism includes a disc bevel gear and a small bevel gear meshing therewith. The clamping claws mesh with the flat threads on the back of the disc bevel gear through threads. When the small bevel gear is screwed through the square hole with a wrench, the disc gear rotates accordingly, and the flat threads on the back of the disc bevel gear simultaneously drive the three clamping claws to move closer to or away from the center to clamp the blind head, with good clamping firmness. However, a wrench is required for driving, and multiple screwing operations are required, which is troublesome, time-consuming and labor-intensive. Summary of the invention

[0005] The purpose of the present invention is to provide a blind head machine in order to solve the above-mentioned problems.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-3As shown, a blind head machine comprises a frame 1, a first chuck device is arranged at one end of the frame 1, a second chuck device is arranged at the other end, and the second chuck device can slide along the length direction of the frame 1, the first chuck device and the second chuck device both comprise a chuck, the chuck comprises a disc body 2, a plurality of claws 3 are slidably connected to the disc body 2, the claws 3 are evenly distributed on the disc body 2, and can clamp the blind head by radial movement, and a rotating disc 4 is rotatably connected inside the disc body 2, a plurality of connecting strips 5 are hingedly connected to the rotating disc 4 along the circumferential direction, and the end of the connecting strip 5 away from the rotating disc 4 is hingedly connected to the claws 3, and a driving mechanism for driving the rotating disc 4 is arranged on the chuck. The rotating adjustment mechanism can place the blind head between the claws 3 during operation, and then the rotating disk 4 can be driven to rotate by the adjusting mechanism. When the rotating disk 4 rotates, the connecting strip 5 will be driven to move accordingly. Since one end of the connecting strip 5 is restricted by the claws 3, the connecting strip 5 moves centripetally, thereby driving the claws 3 to move radially on the disk body 2, so that the claws 3 can be closed, thereby clamping the blind head. After the operation is completed, the rotating disk 4 can be driven to rotate in the opposite direction by the adjusting mechanism, so that the claws 3 can be driven to move away from each other, thereby releasing the blind head. The operation is convenient, time-saving and labor-saving. The adjusting mechanism includes a hinge fixedly connected to the rotating disk 4. The seat 6 is hinged with a pull rod 7 on the hinge seat 6, and a slide groove 8 for the pull rod 7 to pass through and a limit groove 9 connected with the slide groove 8 are opened on the side wall of the chuck, and the limit groove 9 is perpendicular to the slide groove 8. When it is necessary to drive the clamping claw 3 to close, the pull rod 7 can be held and pushed to slide upward along the slide groove 8, so that the steering wheel can be driven to rotate, and the clamping claw 3 can be driven to move and close. After the clamping claw 3 is closed, the pull rod 7 just moves to the connection point between the slide groove 8 and the limit groove 9, and then the pull rod 7 can be rotated to make the pull rod 7 deflected relative to the hinge seat 6 and stuck in the limit groove 9. Then, the limit of the pull rod 7 by the limit groove 9 can be realized. The clamping claw 3 is now locked, so that the clamping claw 3 remains in a clamped state, ensuring that the clamping claw firmly clamps the blind head, and a holding ball 10 is provided at the end of the pull rod 7 away from the connecting seat 14. The presence of the holding ball 10 makes it easier to exert force when pulling the pull rod 7 to move, and it is not easy to slip, and the operation is relatively easy and labor-saving. Among them, a heating cover 11 is provided at the center of the disk body 2, and a quartz heating tube is provided inside the heating cover 11. By energizing the quartz heating tube to make it heat up, the connection between the blind head and the round net can be heated through the heating cover 11, thereby accelerating the solidification of the glue, allowing the blind head and the round net to be quickly combined, thereby improving the installation efficiency of the blind head.

[0021] See also Figure 1 , Figure 4 , Figure 5As shown, two mutually parallel linear guides 12 are arranged on the frame 1, and a driving device connected to the first chuck device is arranged on the frame 1, and the driving device is used to drive the first chuck device to slide on the linear guide 12. Then, by driving the first chuck device to slide by the driving device, the distance between the first chuck device and the second chuck device can be adjusted, so that it can be suitable for round net flower tubes of different lengths. The driving device includes a sliding seat 13 slidably connected to the linear guide 12, and the first chuck device is fixedly installed on the sliding seat 13, a connecting seat 14 is arranged on the sliding seat 13, and a rotating shaft 15 is rotatably connected to the connecting seat 14, and a gear 16 is connected to one end of the rotating shaft 15, and a gear 16 is connected to the other end. The end is connected with a rotating mechanism, and a rack 17 meshing with the gear 16 is fixedly connected to the frame 1. The rotating shaft 15 is driven to rotate by the rotating mechanism, which can drive the gear 16 to rotate. The meshing connection between the gear 16 and the rack 17 can drive the sliding seat 13 to move through the connecting seat 14. Due to the limitation of the linear guide 12, the sliding seat 13 can only slide along the length direction of the linear guide 12, thereby realizing the adjustment of the position of the first chuck device. The operation is relatively convenient and simple. The rotating mechanism includes a first clamping member 18 and a second clamping member 19 for mutually engaging, and the first clamping member 18 is connected to the rotating shaft 15, and the first clamping member 18 is movably connected to the second clamping member 19 The first clamping member 18 and the second clamping member 19 are connected with a force applying rod 20, the first clamping member 18 and the second clamping member 19 can be separated from each other or engaged with each other, and the first clamping member 18 and the second clamping member 19 can rotate relative to each other. When it is necessary to drive the first chuck device to slide, the first clamping member 18 and the second clamping member 19 need to be engaged with each other, and then the force applying rod 20 is held and rotated, so that the first clamping member 18 can be driven to rotate through the second clamping member 19, thereby driving the rotating shaft 15 to rotate and realizing the driving of the first chuck device. After the operation is completed, the first clamping member 18 and the second clamping member 19 can be separated from each other. At this time, the force applying rod 20 is rotated, and the second clamping member 19 cannot be driven to rotate. 19 drives the first clamping member 18 to rotate, thereby failing to drive the rotating shaft 15 to rotate, thereby being able to play a safety role to avoid accidental touching of the force applying rod 20 causing the first chuck device to move, wherein a plurality of protrusions are arranged on the first clamping member 18, and a plurality of grooves for the protrusions to be inserted into are opened on the second clamping member 19, then after the protrusions are inserted into the grooves, the first clamping member 18 and the second clamping member 19 can be engaged with each other, and the first clamping member 18 can be driven to rotate by rotating the second clamping member 19, and after the protrusions are removed from the grooves, the first clamping member 18 and the second clamping member 19 can be separated from each other, so that rotating the second clamping member 19 cannot drive the first clamping member 18 to rotate.

[0022] See also Figure 1 , Figure 6As shown, a plurality of brackets 21 are slidably connected to the linear guide rail 12, and the round screen can be placed on the bracket 21. The support of the bracket 21 to the round screen can prevent the round screen from falling onto the frame 1 when it is detached, thereby preventing the round screen from being deformed due to collision, and playing a role in protecting the round screen. The bracket 21 includes a bottom bracket 22, and a retaining ring 23 is hinged on the bottom bracket 22. A first arc groove 24 is opened on the bottom bracket 22, and a second arc groove 25 matching the first arc groove 24 is opened on the retaining ring 23. When the bracket 21 is in use, the retaining ring 23 can be flipped first to keep it away from the base 22, and then the round net can be placed inside the first arc groove 24, and then the retaining ring 23 can be flipped to cover the base 22, so that the round net can be inserted into the second arc groove 25. The first arc groove 24 and the second arc groove 25 are combined to form a space for fixing the round net, thereby fixing the round net and providing support for the round net. When the round net needs to be disassembled, only the retaining ring 23 needs to be flipped to keep it away from the base 22, and the operation is relatively convenient and simple.
