Description

Technical Field

[0001] This invention relates to the field of artificial turf production equipment technology, and in particular to an automatic packaging device for artificial turf. Background Technology

[0002] Artificial turf, as an important decorative building material, is widely used in various scenarios. Since artificial turf is usually laid over a large area, its surface smoothness and the tightness of the packaging roll become important factors affecting the convenience of later construction. After the conventional artificial turf is processed and produced by automated equipment, it is generally cut, rolled and packaged. The packaging process is usually done manually. During the packaging process, the packaging material needs to be rolled in the same direction on the outside of the rolled artificial turf. After fixing or sealing, the packaging is completed. Since the rolled artificial turf is large, this rolling process consumes a lot of manpower and time, causing great inconvenience to the production of artificial turf.

[0003] Existing roll packaging equipment can generally only complete the winding of the fabric, but cannot fix it. Moreover, during the winding process, the fabric may have problems such as curling and wrinkling, which directly affects the surface flatness of the artificial turf packaging.

[0004] Therefore, how to provide a packaging device that can package rolls of artificial turf and ensure good adhesion between the packaging paper and the surface of the artificial turf after packaging has become an urgent technical problem to be solved. Summary of the Invention

[0005] In view of this, the present invention proposes an automatic packaging device for artificial turf, which aims to improve the fit between the packaging fabric and the rolled artificial turf.

[0006] The technical solution of this invention is implemented as follows: This invention provides an automatic packaging device for artificial turf, comprising: a support roller, a first motor, an unwinding roller, a second motor, a winding turntable, grippers, a third motor, a first linear drive device, and a heating rod. Two support rollers are arranged horizontally parallel to each other. The first motor drives the support rollers to rotate around their own axes. The unwinding roller is arranged horizontally parallel to the support rollers above them. The second motor drives the unwinding roller to rotate around its own axis. Two winding turntables are arranged on both sides of the support rollers along their length, and the winding turntables are located between the support rollers and the unwinding rollers. The third motor drives the winding turntables to rotate around their own axes. The axis of the winding turntables is parallel to the axis of the support rollers. A gripper is provided on the side of the winding turntable closest to the support rollers. The gripper selectively passes under the unwinding roller as the winding turntable rotates, and the gripper can clamp the packaging material under the unwinding roller. The heating rod is parallel to the support rollers. The first linear drive device drives the heating rod to move horizontally and selectively pass between the support rollers and the unwinding roller.

The driving direction of the second linear drive device is parallel to the plane where the winding turntable is located. The gripper is fixedly disposed at the driving end of the second linear drive device. The driving directions of the two second linear drive devices are parallel.

[0009] In some embodiments, the second linear drive is arranged along the radial direction of the winding turntable.

[0010] In some embodiments, a third linear drive device and a blade are also included. The third linear drive device is fixedly connected to the heating rod, and the driving direction of the third linear drive device is parallel to the length direction of the heating rod. The blade is fixedly disposed at the driving end of the third linear drive device, and the blade is disposed on the side where the unwinding roller is located.

[0011] In some embodiments, a fourth linear drive and a hot melt adhesive coating die are also included. The hot melt adhesive coating die is parallel to the unwinding roller, and the fourth linear drive drives the hot melt adhesive coating die to move horizontally and selectively abut against the side of the unwinding roller away from the heating rod.

[0012] In some implementations, the fourth linear drive is mounted on the frame.

[0013] In some embodiments, the length of the hot melt adhesive coating die is the same as the length of the unwinding roller, and the two ends of the hot melt adhesive coating die are flush with the two ends of the unwinding roller.

[0014] In some embodiments, the fourth linear drive device includes at least two first drive cylinders, and a plurality of first drive cylinders are arranged in an array along the length direction of the hot melt adhesive coating die head. The drive end of the first drive cylinder is fixedly connected to the hot melt adhesive coating die head, and the first drive cylinder drives the hot melt adhesive coating die head to move in the horizontal direction and selectively abut against the side of the unwinding roller away from the heating rod.

[0015] In some implementations, the first motor, the second motor, and the third motor are all servo motors.

[0017] The automatic artificial turf packaging device of the present invention has the following advantages over the prior art:

[0018] This invention provides an automatic packaging device for artificial turf, which can package rolls of artificial turf. The artificial turf is rolled between two support rollers, which rotate in the same direction to drive the roll of artificial turf to rotate in place. The unwinding roller unwinds the packaging fabric, and the grippers hold the fabric and wrap it around the surface of the roll of artificial turf under the drive of the winding turntable. Finally, a heating rod is driven by a first linear drive device to press against the surface of the packaging fabric and heat-melt the packaging fabric, thereby fusing and fixing the outermost two layers of packaging fabric to achieve automatic packaging. The remaining packaging fabric is broken by the heat-melting action or by manual cutting. Attached Figure Description

[0030] like Figure 1 As shown, combined with Figure 2-4The automatic artificial turf packaging device of the present invention includes: a support roller 1, a first motor 2, an unwinding roller 3, a second motor 4, a winding turntable 5, a gripper 6, a third motor 7, a first linear drive device 8, and a heating rod 9. Its structure is as follows: two support rollers 1 are horizontally parallel and rotatably mounted on a frame, rotating around their own axes; the first motor 2 is mounted on the frame and drives the two support rollers 1 to rotate in the same direction; the two support rollers 1 support the turf rolls to be packaged; the unwinding roller 3 is horizontally positioned above the support rollers 1 and rotatably mounted on the frame, parallel to the axis of the support roller 1; the second motor 4 is mounted on the frame 1 and drives the unwinding roller 3 to rotate around its axis; the second motor 4 drives the unwound packaging fabric on the unwinding roller 3 to unwind and enter the lower packaging space; two winding turntables 5 are respectively located at both ends of the support roller 1 along its length, and the two winding turntables 5 are discs. The winding turntable 5 is mounted on the frame, with its axis of rotation being its own axis. The axis of rotation of the winding turntable 5 is parallel to the axis of rotation of the support roller 1, and the winding turntable 5 is located between the support roller 1 and the unwinding roller 3. Preferably, the axis of rotation of the winding turntable 5 is located within the symmetrical plane of the two support rollers 1. The third motor 7 drives the winding turntable 5 to rotate. Each winding turntable 5 has a gripper 6 on the side near the support roller 1. The gripper 6 rotates with the winding turntable 5. The gripper 6 can selectively grip or release the unwound and hanging packaging fabric on the unwinding roller 3. The surface of the frame 1 is also provided with a first linear drive device 8. The first linear drive device 8 drives the heating rod 9 to reciprocate in the horizontal direction. The axis of the heating rod 9 is parallel to the axis of the support roller 1, and the driving direction of the first linear drive device 8 is perpendicular to the axis of the support roller 1. Under the drive of the first linear drive device 8, the heating rod 9 selectively passes between the support roller 1 and the unwinding roller 3.

[0031] In the above embodiments, the gripper 6 selectively grasps the unwound and drooping packaging fabric, and as the winding turntable 5 rotates, it wraps the packaging fabric around the outside of the rolled turf. During the winding process, the packaging fabric passes between the rolled turf and the support roller 1, at which time the support roller 1 rotates accordingly, so that there is static friction contact between the turf and the packaging fabric, and between the packaging fabric and the support roller 1. After winding at least one turn, the heating rod 9, driven by the first linear drive device 8, abuts against the packaging fabric that is not wound on the surface of the rolled turf, and forces this part of the packaging fabric to adhere tightly. On the surface of the rolled turf, during this process, the second motor 4 can be kept stationary to keep the packaging fabric taut. Once the packaging fabric is pressed tightly against the rolled turf, the heating rod 9 heats it, causing the packaging fabric to heat-melt and bond, thus completing the packaging. At this point, the outermost ring of packaging fabric melts at the heat-melted part, and the inner ring of packaging fabric bonds with the outer ring of heat-melted packaging fabric. The grippers 6 then release, completing the packaging of the rolled turf. This winding method can improve the fit between the packaging fabric and the rolled turf. At the same time, using machine operation to replace manual operation can reduce the difficulty of operation and labor costs.

[0032] Specifically, such as Figure 2 and Figure 3 As shown, the unwinding roller 3 rotates clockwise and releases the packaging fabric, while the support roller 1 and the super-rotor 5 both rotate clockwise. The corresponding rolled turf rotates counterclockwise, and the packaging fabric, fixed by the gripper 6, wraps the rolled turf counterclockwise, thus completing the packaging.

[0033] In some embodiments, a second linear drive device 10 is also included. Each winding turntable 5 is fixedly provided with a second linear drive device 10 on one side surface near the support roller 1. The driving direction of the second linear drive device 10 is parallel to the plane where the winding turntable 5 is located. The gripper 6 is fixedly provided at the driving end of the second linear drive device 10. The driving directions of the two second linear drive devices 10 are parallel.

[0034] In the above embodiments, the second linear drive device 10 can change the rotation radius of the gripper 6 during its revolution. By changing the radius, it can adapt to the packaging of turf rolls of different diameters. On the other hand, it can change the tightness between the packaging material and the surface of the turf roll during the packaging process. Furthermore, it can adapt to the position of the packaging material during the unwinding process of the unwinding roller 3, thereby enabling the gripper 6 to adjust its position to accurately grasp the packaging material.

[0035] In some embodiments, the second linear drive device 10 is arranged along the radial direction of the winding turntable 5.

[0036] In the above embodiments, the second linear drive device 10 arranged radially can adjust the position of the gripper 6 more quickly and maximize the adjustment range.

[0037] In some embodiments, the device further includes a third linear drive device 11 and a blade 12. The third linear drive device 11 is fixedly connected to the heating rod 9. The driving direction of the third linear drive device 11 is parallel to the length direction of the heating rod 9. The blade 12 is fixed to the driving end of the third linear drive device 11 and is positioned facing the side where the unwinding roller 3 is located.

[0038] In the above embodiments, the heating rod 9 heat-melts the packaging fabric to achieve separation. However, this method easily creates uneven tear gaps at the break. Solutions include: setting a punch on the heating rod 9, using the punch's squeezing action to create stress concentration points in the heat-melted portion, thus forming a more uniform fracture. However, this method still easily results in fracture defects. To further solve this technical problem, a blade 12 is set on the heating rod 9. The blade 12 moves in a linear reciprocating motion driven by the third linear drive device 11. When the heating rod 9 is pressed against the surface of the packaging fabric, the blade 12 moves linearly, cutting the taut, unused packaging fabric to achieve a better fracture effect. Simultaneously, for any excess portion of the fracture, the first motor 2 and the second motor 4 can rotate synchronously to drive the packaging fabric to rotate relative to the heating rod 9, completing the heat-melting seal of the remaining packaging fabric.

[0039] In some embodiments, a fourth linear drive device 13 and a hot melt adhesive coating die 14 are also included. The length direction of the hot melt adhesive coating die 14 is parallel to the axis of the unwinding roller 3. The fourth linear drive device 13 drives the hot melt adhesive coating die 14 to move in the horizontal direction and selectively abut against the side of the unwinding roller 3 away from the heating rod 9.

[0040] In the above embodiments, when the hot melt coating die 14 contacts the packaging fabric on the unwinding roller 3, it can extrude hot melt adhesive onto the surface of the packaging fabric. The coating position of the hot melt adhesive will ultimately be on the side of the packaging fabric away from the heating rod 9 when the rolled lawn is being packaged. Under the heating of the heating rod 9, the hot melt adhesive melts and adheres to the packaging fabric on both sides. When the heating rod 9 moves away or stops working, the connecting part of the packaging fabric solidifies, thereby completing the packaging. Setting up the hot melt adhesive coating die 14 can avoid packaging fabrics that are not hot melt materials, and the hot melt adhesive can improve the sealing performance and connection stability of the packaging fabric.

[0041] In some embodiments, the length of the hot melt adhesive coating die 14 is the same as the length of the unwinding roller 3, and the ends of the two are flush with each other.

[0042] In the above embodiments, the hot melt adhesive coating die head 14 can extrude hot melt adhesive along the length direction of the unwinding roller 3, thereby achieving uniform hot melt adhesive coating and improving packaging connection performance and sealing.

[0043] In some embodiments, the fourth linear drive device 13 includes at least two first drive cylinders 131, and the plurality of first drive cylinders 131 are arranged in an array along the length direction of the hot melt adhesive coating die head 14. The drive end of the first drive cylinder 131 is fixedly connected to the hot melt adhesive coating die head 14. The first drive cylinder 131 drives the hot melt adhesive coating die head 14 to move in the horizontal direction and selectively abuts against the side of the unwinding roller 3 away from the heating rod 9.

[0044] In the above embodiments, since the structure of the hot melt adhesive coating die head 14 may be relatively large and its weight is relatively large, using multiple first drive cylinders 131 for driving is more conducive to ensuring driving stability.

[0045] In some embodiments, the first motor 2, the second motor 4, and the third motor 7 are all servo motors.

[0046] In the above embodiment, since the rotation angle of the rolled artificial turf needs to be precisely controlled during the packaging process, a servo motor is used to facilitate precise linkage control.

[0047] In some embodiments, the first linear drive device 8 includes at least two second drive cylinders 81, and the plurality of second drive cylinders 81 are arranged in an array along the length direction of the heating rod 9. The drive end of the second drive cylinder 81 is fixedly connected to the heating rod 9. The second drive cylinder 81 drives the heating rod 9 to move in the horizontal direction and selectively pass between the support roller 1 and the unwinding roller 3.

[0048] In the above embodiments, the heating rod 9 needs to heat the packaging fabric on the one hand, and on the other hand, it needs to work with the second motor 4 and the gripper 6 to tension the packaging fabric. By using multiple second drive cylinders 81, the horizontal driving force on the heating rod 9 can be increased, thereby achieving a good tensioning effect on the packaging fabric.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
