[0047] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0048] like Figure 1-4 As shown, a multi-strap strapping machine comprises a frame 1, a conveying mechanism 2 for conveying tiles, a strapping storage mechanism 3 for storing strapping straps, a strap clamping mechanism 4 for clamping the strapping straps, a tightening mechanism 5 for tightening the strapping straps, a guiding mechanism 6 for guiding the strapping strap path, a heat sealing mechanism 7 for heat sealing the strapping straps, a strap cutting mechanism 8 for cutting the strapping straps, and a cam assembly 9;

[0049] The cam assembly 9 includes a motor 91, a rotating shaft 92 connected to the motor 91, a tightening cam 93 provided on the rotating shaft 92 and connected to the tightening mechanism 5, a heat sealing cam 94 provided on the rotating shaft 92 and connected to the heat sealing mechanism 7, and a tape cutting cam 95 provided on the rotating shaft 92 and connected to the tape cutting mechanism 8;

[0050] The motor 91 drives the rotating shaft 92 to rotate, and the tightening cam 93 rotates following the rotating shaft 92, so that the tightening mechanism 5 moves up and down following the shape change of the tightening cam 93, thereby tightening the strapping belt;

[0051] The heat sealing cam 94 rotates along with the rotating shaft 92, so that the heat sealing mechanism 7 moves up and down along with the shape change of the heat sealing cam 94 to achieve heat sealing;

[0052] The tape cutting cam 95 rotates following the rotating shaft 92 , so that the tape cutting mechanism 8 moves up and down following the shape change of the tape cutting cam 95 , thereby achieving tape cutting.

[0053] The frame 1 is used to install the conveying mechanism 2, the belt storage mechanism 3, the clamping mechanism 4, the tightening mechanism 5, the guiding mechanism 6, the heat sealing mechanism 7, the belt cutting mechanism 8 and the cam assembly 9 to ensure that the strapping process can proceed smoothly.

[0054] like Figure 2 As shown, the conveying mechanism 2 is used to convey tiles so that the tiles can smoothly enter the bundling machine for bundling. Specifically, the conveying mechanism 2 includes a conveying motor 21, a transmission shaft 22 connected to the conveying motor 21, and a conveying belt 23 wound around the conveying shaft 22. The conveying motor 21 drives the transmission shaft 22 to rotate, and the transmission belt 23 rotates with the conveying shaft 22. The tiles are arranged on the transmission belt 23, so they can move with the transmission belt 23, thereby realizing the transmission of the tiles.

[0055] The belt storage mechanism 3 is used to store strapping belts, and includes a belt storage fixing frame 31 arranged on the frame and a belt storage reel 32 arranged on the belt storage fixing frame 31. The number of the belt storage reels 32 can be one or more, and the specific number can be set according to actual needs.

[0056] like Figure 5As shown, the entrainment mechanism 4 is used to clamp or loosen the strapping belt as needed to achieve bundling. The entrainment mechanism 4 includes an entrainment motor 41, an entrainment shaft 42 connected to the entrainment motor 41, an entrainment transmission arm 43 arranged on the entrainment shaft 42, and a clamping claw 44 arranged at the end of the entrainment transmission arm 43. When the tile enters the strapping machine, the height of the clamping claw 44 is less than the height of the tile, and the storage disc 32 is arranged on the top of the frame 1, so the tile moves forward between the storage disc 32 and the clamping claw 44, and in the process of moving forward, it hits the strapping belt and drives the strapping belt forward. At this time, the storage disc loosens the strapping belt under the action of the tile until the tile stops moving. At this time, the strapping belt is wrapped around the three sides of the tile, and the entrainment motor 41 drives the entrainment shaft 42 to rotate, and the entrainment transmission arm 43 rotates with the entrainment shaft 42, so that the tile moves from the bottom of the tile to the top of the tile. In this way, the strapping belt wraps around the tile once and can be tightened and cut.

[0057] like Figure 6 As shown, specifically, the clamping jaw 44 includes a first clamping jaw 441, a second clamping jaw 442 and a clamping jaw cylinder 443 for driving the first clamping jaw 441 and the second clamping jaw 442 to move closer to or away from each other. The first clamping jaw 441 and the second clamping jaw 442 are arranged on the clamping jaw cylinder 443, and move closer to or away from each other under the action of the clamping jaw cylinder to achieve the clamping or loosening of the strapping belt.

[0058] Preferably, in order to clamp the strapping belt more conveniently, the strapping mechanism 4 further includes a telescopic cylinder 45, which is fixed to the strapping transmission arm 43 and is used to drive the clamping claw 44 to move closer to or away from the strapping belt, thereby clamping or loosening the strapping belt.

[0059] During operation, the clamp 44 is in a state of being away from the strapping belt, and the telescopic cylinder 45 drives the clamp 44 to move towards the strapping belt, so that the strapping belt is located between the first clamp 441 and the second clamp 442. The clamp cylinder 443 drives the first clamp 441 and the second clamp 442 to approach each other and clamp the strapping belt, and the entrainment motor 41 drives the entrainment shaft 42 to rotate, so that the height of the clamp 44 is lower than the height of the lower surface of the tile, and the tile moves to hit the strapping belt for bundling.

[0060] like Figure 7As shown, the tightening mechanism 5 is used to tighten the strapping belt so that the strapping belt is tightly tied to the ceramic tile, and includes a tightening fixing frame 51 arranged on the frame 1, a tightening support 52 arranged on the tightening fixing frame 51, a first tightening guide wheel 53 arranged on the tightening support 52, a tightening connecting rod 54 connected to the tightening support 52, and a tightening reset spring 55 connecting the first tightening guide wheel 53 and the tightening fixing frame 51, wherein one end of the tightening connecting rod 54 is fixed to the tightening support 52, and the other end abuts against the tightening cam 93, and when the height of the first tightening guide wheel 53 is the lowest, it abuts against the strapping belt, so when it rises, the strapping belt retracts, thereby achieving the tightening of the strapping belt.

[0061] A tightening guide hole is provided on the tightening support 52, and the inner diameter of the tightening guide hole is larger than the outer diameter of the tightening link 54, ensuring that the tightening link 54 can move up and down in the tightening guide hole. One end of the tightening reset spring 55 is fixed to the first tightening guide wheel 53, and the other end is fixed to the tightening fixing frame 51, and it is always in an extended state, ensuring that the first tightening guide wheel 53 can move downward under the restoring force of the tightening reset spring 55, so as to facilitate the first tightening guide wheel 53 to loosen the strapping belt.

[0062] During operation, the tightening cam 93 rotates, and when the long end of the tightening cam 93 abuts against the tightening link 54, the tightening link 54 moves upward and pushes the first tightening guide wheel 53 to move upward, so that the first tightening guide wheel 53 moves upward against the strapping belt, thereby tightening one end of the strapping belt.

[0063] In order to reduce friction, a second tightening guide wheel 56 is provided at the end of the tightening link 54 , and the second tightening guide wheel 56 abuts against the tightening cam 93 .

[0064] Correspondingly, such as Figure 7-9 As shown, in order to achieve the fixation of both ends of the strapping belt and facilitate the smooth tightening work, it also includes a fastening mechanism 10 sleeved on the strapping belt and a pressing mechanism 11 for pressing the strapping belt against the tile. The fastening mechanism 10 is fixed on the frame 1, and includes a switch 101 and a clamping structure 102. The switch controls whether the clamping structure 102 is clamped, thereby achieving the fixation of one end of the strapping belt. The pressing mechanism 11 includes a pressing head 111, a pressing link 112 connected to the pressing head 111, and a pressing reset spring 113 connected to the pressing head 111. The pressing head 111 is located directly above the tile. The end of the pressing link 112 abuts against the tightening cam 93. When the long end of the tightening cam 93 abuts against the pressing link 112, the pressing head 111 moves downward, thereby pressing the strapping belt against the tile, thereby achieving the fixation of the other end of the strapping belt.

[0065] In order to reduce friction, a pressing guide wheel 114 is provided at the end of the pressing link 112 , and the pressing guide wheel 114 abuts against the tightening cam 93 .

[0066] like Figure 7 As shown, the guide mechanism 6 is used to guide the path of the strapping belt, and includes a plurality of guide wheels 61. The specific positions of the guide wheels 61 can be set according to actual needs. In this embodiment, at least two of the guide wheels 61 are located above the first tightening guide wheel 53, and the strapping belt passes between the two guide wheels 61 and the first tightening guide wheel 53 to facilitate tightening.

[0067] like Figure 10-11 As shown, the heat sealing mechanism 7 is used for heat sealing the strapping belt, and includes a heat sealing fixed frame 71, a heat sealing member 72 that reciprocates along the heat sealing fixed frame 71, a heat sealing movable frame 73 connected to the heat sealing member 72, a heat sealing connecting rod 74 connected to the heat sealing movable frame 73, and a heat sealing return spring 75 connecting the heat sealing movable frame 73 and the heat sealing fixed frame 71, wherein one end of the heat sealing connecting rod 74 is fixed to the heat sealing movable frame 73, and the other end abuts against the heat sealing cam 94.

[0068] In order to achieve a slidable connection between the heat sealing member 72 and the heat sealing fixed frame 71, the heat sealing mechanism 7 also includes a slider 76 and a slide groove 77 provided on the heat sealing fixed frame 71. The slide groove 77 matches the slider 76, and the heat sealing member 72 is fixed on the slider 76. Therefore, under the action of external force, the heat sealing member 72 can move along the heat sealing fixed frame 71.

[0069] During operation, the heat sealing cam 94 rotates, and when its short end abuts against the heat sealing connecting rod 74, the heat sealing movement 73 moves toward the direction close to the strapping belt under the action of the heat sealing return spring 75 until the heat sealing member 72 moves to the top of the strapping belt for heat sealing. When the long end of the heat sealing cam 94 abuts against the heat sealing connecting rod 74, the heat sealing member leaves the strapping belt.

[0070] In order to reduce friction, a heat sealing guide wheel 78 is provided at the end of the heat sealing connecting rod 74, and the heat sealing guide wheel 78 and the heat sealing cam 94 abut against each other.

[0071] like Figure 8-9As shown, the strap cutting mechanism 8 is used to cut the strapping strap, and comprises a cutter 81, a cutter connecting rod 82 connected to the cutter 81, and a cutter reset spring 83 connected to the cutter 81. The cutter 81 is located directly above the tile, and the end of the cutter connecting rod 82 abuts against the strap cutting cam 95. When the long end of the strap cutting cam 95 abuts against the cutter connecting rod 82, the cutter 81 moves downward, presses the strapping strap against the tile, and cuts off the strapping strap.

[0072] In order to reduce friction, a cutter guide wheel 84 is provided at the end of the cutter connecting rod 82 , and the cutter guide wheel 84 abuts against the belt cutting cam 95 .

[0073] like Figure 3-4 As shown, the cam assembly 9 is used to control the tightening mechanism 5 to perform tightening action, the heat sealing mechanism 7 to perform heat sealing action, and the tape cutting mechanism 8 to perform tape cutting action, and includes a motor 91, a rotating shaft 92 connected to the motor 91, a tightening cam 93 arranged on the rotating shaft 92 and connected to the tightening mechanism 5, a heat sealing cam 94 arranged on the rotating shaft 92 and connected to the heat sealing mechanism 7, and a tape cutting cam 95 arranged on the rotating shaft 92 and connected to the tape cutting mechanism 8; the motor is used to drive the rotating shaft to rotate, so that the tightening cam 93, the heat sealing cam 94 and the tape cutting cam 95 on the rotating shaft can rotate to realize their respective functions.

[0074] like Figure 12-13 As shown, the tightening cam 93 is arranged on the rotating shaft 92, and includes a first tightening cam 931 and a second tightening cam 931, wherein the first tightening cam 931 abuts against the second tightening guide wheel 56 at the end of the tightening link 54, and has an eccentric structure, and the outer periphery is composed of two arc surfaces with different radii, that is, when the long radius end of the first tightening cam 931 abuts against the second tightening guide wheel 56, the strapping belt is tightened, and when the short radius end of the first tightening cam 931 abuts against the second tightening guide wheel 56, the strapping belt is loosened. The second tightening cam 932 abuts against the pressing guide wheel 114 at the end of the pressing link 112, and has an eccentric structure, and the outer periphery is composed of two arc surfaces with different radii, wherein when the long radius arc surface abuts against the pressing guide wheel 114, the pressing head 111 presses the strapping belt, and when the short radius arc surface abuts against the pressing guide wheel 114, the pressing head 111 loosens the strapping belt.

[0075] like Fig.14 As shown, the heat sealing cam 94 is arranged on the rotating shaft, and has an eccentric structure. The outer periphery is composed of two arc surfaces with different radii. When the long radius end thereof abuts against the heat sealing guide wheel 78 at the end of the heat sealing connecting rod 74, the heat sealing member 72 leaves the strapping belt, and when the short radius end thereof abuts against the heat sealing guide wheel 78, the heat sealing member 72 performs heat sealing.

[0076] like Fig.15 As shown, the strap cutting cam 95 is arranged on the rotating shaft, and has an eccentric structure. The outer periphery is composed of three arc surfaces with different radii. When the short radius end thereof abuts against the cutter guide wheel 84 at the end of the cutter connecting rod 82, the cutter 81 leaves the strapping belt. When the middle radius end abuts against the cutter guide wheel 84, the cutter 81 presses the strapping belt. When the long radius end abuts against the cutter guide wheel 84, the cutter presses the strapping belt again and completely cuts off the strapping belt.

[0077] The multi-strap strapping machine provided by the present invention controls the tightening mechanism 5, the heat sealing mechanism 7 and the strap cutting mechanism 8 through the cam assembly 9, thereby realizing multi-strap strapping and improving production efficiency. On the other hand, the control of multiple mechanisms can be achieved through only one set of cam assemblies, thereby saving driving energy and reducing production costs.

[0078] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
