Description

Technical Field

[0001] The invention relates to the field of building material packaging, in particular to a cement prefabricated board packaging device. Background Art

[0002] At present, bulk cement raw materials are directly processed into the required building materials by pre-making cement in the factory. After making, packaging and transporting to the construction site, operators directly use prefabricated panels to assemble and assemble them at the construction site to build the building. Since prefabricated panels do not require operators to perform tedious processes such as cement mixing, pouring, and demoulding at the construction site, they are widely used in various construction scenarios.

[0003] After the cement precast panels go through the procedures of material selection, batching, mixing, molding, curing, cutting, etc. in the factory, they are formed into precast panels with several holes inside in the length direction. Finally, the cement precast panels usually need to be packaged before transportation. The common packaging method is that the operator precasts the cement panels and stacks them, and places the cement precast panels on pallets or directly on the ground, and fixes the strapping tape to the outside of the cement precast panels through the strapping tape tensioner to achieve the bundling of the cement precast panels. Sometimes, in order to reduce the erosion of rainwater when the cement precast panels are stored outdoors to ensure that they always remain dry, the operator will wrap the stretch film around the outside of the cement precast panels for protection. After the cement precast panels are covered with the stretch film, the dust splashing of the cement precast panels can also be effectively reduced.

[0004] With regard to the above-mentioned related technologies, when packing cement precast panels, it is inconvenient to pack the stacked cement precast panels because they have a large weight and a large volume after being stacked. It is difficult for operators to pass the packing tape or stretch film through the bottom side of the cement precast panels for wrapping. If an automatic wrapping device is used to wrap the cement precast panels, the covering area is small and the cement precast panels cannot be fully wrapped. Summary of the invention

[0011] By adopting the above technical solution, when the cement precast board pile reaches the rotating base, the rotating base starts to rotate, and the film clamping claws rotate together with the rotating base, and the cement precast board pile starts to be transversely wound around the film. After the film winding is completed, the knife cylinder pushes the knife to move toward the cement precast board pile and cuts the stretched film.

DETAILED DESCRIPTION

[0029] The present invention is further described in detail below in conjunction with all the accompanying drawings.

[0030] The embodiment of the invention discloses a cement prefabricated board packaging device.

[0031] Reference Figures 1 to 7 A cement prefabricated board packaging device comprises a frame, wherein the frame is provided with a feeding position, a horizontal cutting knife assembly 5, a rotating ring 11, a gantry 1, a transverse film winding assembly 3 and a pallet bin 4 in sequence along the length direction, a first conveyor belt 2 is provided along the length direction of the frame, the feeding position is located at a side of the first conveyor belt 2 away from the rotating ring 11, the rotating ring 11 is rotatably connected to the gantry 1, a transverse rod 112 for placing a stretch film is provided on a side of the rotating ring 11 away from the gantry 1, a gear ring 111 is provided circumferentially, and the gantry 1 is provided with a rotating motor 12, the rotating motor 12 is provided with a driving gear 121 adapted to the gear ring 111, the first conveyor belt 2 includes two sections, an escape space 21 for avoiding the stretch film on the transverse rod 112 is provided between the two sections of the first conveyor belt 2, the horizontal cutter assembly 5 is located at one side of the escape space 21, the horizontal cutter assembly 5 is used to absorb and cut the stretch film, the transverse film winding assembly 3 is used to pack the cement prefabricated board stack in the horizontal direction, and the pallet warehouse 4 is located at one side of the end of the first conveyor belt 2.

[0032] The operator places the cement precast panels stacked at the loading place to form a cement precast panel pile, and transports the cement precast panel pile to the gantry 1 through the first conveyor belt 2. When the cement precast panels pass through the avoidance space 21 between the two first conveyor belts 2, the rotating motor 12 drives the swivel 11 to rotate, and at this time, the horizontal cutter assembly 5 continues to absorb the stretch film on the transverse rod 112 and abuts the stretch film against the lower side of the cement precast panel. As the swivel 11 drives the transverse rod 112 to rotate, the stretch film on the transverse rod 112 begins to wrap around the vertical direction of the cement precast panel. When the end of the cement precast panel pile is about to pass through the avoidance space 21, the horizontal cutter assembly 5 cuts off and absorbs the stretch film to wait for the next group of cement precast panel piles to be wrapped and wrapped.

[0033] After completing the vertical winding, the cement precast board pile will continue to move along the first conveyor belt 2, and will be wrapped with a transverse stretch film at the transverse winding film assembly 3. The cement precast board pile that has completed the transverse winding will continue to be transported to the end of the first conveyor belt 2. At this time, the pallet 101 will be taken out of the pallet warehouse 4 and placed at the end of the first conveyor belt 2. After the cement precast board pile is sent out of the first conveyor belt 2, it will be placed on the pallet 101. At this time, the operator can transfer the cement precast board pile that has completed the winding and wrapping through the pallet 101.

[0034] The horizontal film winding assembly 3 includes a slider 31, a vertical cutter, and a rotating base 32. A slide groove is provided inside the gantry 1. The slider 31 is slidably connected to the slide groove. The gantry 1 is provided with a lifting motor 312. The lifting motor 312 is provided with a lead screw 311. The lead screw 311 is located inside the slide groove. The slider 31 is provided with a threaded hole adapted to the lead screw 311. The slider 31 extends to the inside of the gantry 1 and is provided with a vertical rod 313 for placing the stretch film. The rotating base 32 is located on the side of the gantry 1 away from the swivel 11. The rotating base 32 is provided with a second conveyor belt 33. The lower side of the rotating base 32 is provided with a base motor for driving the rotating base 32 to rotate. The vertical cutter is located on one side of the rotating base 32. A gate knife 35 is provided on the upper side of the vertical cutter. The vertical cutter is provided with a gate knife cylinder 36 for pushing the gate knife 35 close to and away from the rotating base 32. In order to clamp the stretched film that has been cut, and to facilitate wrapping and winding the cement precast board pile at the rear. A film clamping jaw 34 is provided on the upper side of the rotating base 32, and the film clamping jaw 34 is located on a side close to the vertical cutter. When the gate knife 35 completes cutting of the stretch film, the film clamping jaw 34 is located below the gate knife 35. When the device is used for the first time, the operator manually pulls out the stretch film on the vertical rod 313 and places it on the film clamping jaw 34, and fixes the stretch film through the film clamping jaw 34.

[0035] When the last cement precast board pile is finished winding, the rotating base 32 rotates to Figure 4The cut stretch film will fall downward under the action of gravity. Since the film clamping jaw 34 is located below the gate knife 35, the film clamping jaw 34 can clamp the end of the falling stretch film. When the rotating base 32 rotates, the film clamping jaw 34 will rotate with the rotating base 32, thereby effectively facilitating the covering of the stretch film on the cement precast board pile. It can also effectively facilitate the clamping of the stretch film to prevent the end of the stretch film from being entangled in the first conveyor belt 2 or the second conveyor belt 33. In order to prevent the film clamping jaw 34 from being entangled in the stretch film, the vertical position of the film clamping jaw 34 should be slightly lower than the lower edge of the stretch film on the vertical rod 313 when the slider 31 is at the lowest position.

[0036] In actual production, due to the existence of a certain angle between the vertical rod 313 and the film clamping jaw 34, the film clamping jaw 34 has a too small opening, and the like, the stretch film may not fall well into the film clamping jaw 34. In order to clamp the cut stretch film more effectively, the upper end of the film clamping jaw 34 is provided with a bell mouth, which is jointly formed by the two claws of the film clamping jaw 34, that is, the upper end opening of the film clamping jaw 34 is larger than the lower side. Therefore, when the end of the stretch film falls downward under gravity, it will move toward the inside of the clamping jaw along the bell mouth, and finally guide the fall of the stretch film. In order to further adjust the clamping angle of the film clamping jaw 34, the film clamping jaw 34 is rotatably connected to the rotating base 32, and a socket and a pin are provided on the rotating base 32 to fix the position of the rotating jaw. The operator can achieve a better clamping effect by adjusting the angle between the film clamping jaw 34 and the vertical rod 313.

[0037] When the cement precast board pile reaches the transverse film winding assembly 3, the slider 31 is at the lowest position. When the cement precast board pile approaches the second conveyor belt 33 from the first conveyor belt 2, the second conveyor belt 33 starts to rotate synchronously to realize the transfer between the cement precast board pile and the two different conveyor belts. When the cement precast board pile completely reaches the rotating base 32, the base motor drives the rotating base 32 to rotate, and at the same time, the lifting motor 312 drives the lead screw 311 to rotate, thereby realizing the lifting of the slider 31. As the rotating base 32 rotates and the lead screw 311 drives the slider 31 to lift, the cement precast board pile is wound upward from the lower side of the cement precast board pile, thereby realizing the transverse winding of the cement precast board pile. At this time, the gate cylinder 36 pushes the gate 35 toward the cement precast board pile, and the gate 35 cuts the stretch film. The cement precast board pile that has completed transverse winding is sent out of the transverse film winding assembly 3 through the second conveyor belt 33, and the cement precast board pile that has completed the stretch film winding is continued to be sent to the end of the first conveyor belt 2 at the rear.

[0038] In order to facilitate the cutting and adsorption of the stretch film on the rotating ring 11, so as to facilitate the subsequent winding of the cement precast board pile. The horizontal cutter assembly 5 includes a lower inclined rod 52 and an upper inclined rod 51, the upper side of the upper inclined rod 51 is close to the rotating ring 11, and the lower side of the lower inclined rod 52 is away from the rotating ring 11. The upper inclined rod 51 is slidably connected with the lower inclined rod 52, and a telescopic cylinder 55 for pushing the upper inclined rod 51 to extend and retract is provided inside the lower inclined rod 52. A vacuum suction port 54 and a telescopic cutter 53 are provided on the upper end surface of the upper inclined rod 51. A cutter cylinder 531 for pushing the telescopic cutter 53 is provided inside the upper inclined rod 51, and a vacuum generator 541 is provided inside the vacuum suction port 54.

[0039] In this embodiment, the horizontal cutter assembly 5 is installed below the first conveyor belt 2, and the first conveyor belt 2 is provided with an escape groove for escape. Figure 2 From the perspective of viewing, the telescopic cutter 53 is located on the left side of the vacuum suction port 54, so the rotation direction of the rotating ring 11 is clockwise. When the telescopic cutter 53 is located on the right side of the vacuum suction port 54, the rotation direction of the rotating ring 11 should be counterclockwise. This arrangement is to enable the vacuum suction port 54 to better absorb the stretched film.

[0040] When used for the first time, the operator pulls the stretch film out of the transverse rod 112 and places it at the vacuum suction port 54, and the stretch film at the vacuum suction port 54 is adsorbed by the vacuum generator 541. After completing the vertical winding of the previous cement precast board pile, the transverse rod 112 should be higher than the upper end surface of the first conveyor belt 2, and the position of the transverse rod 112 should be on the same side as the horizontal cutter assembly 5. At this time, the telescopic cylinder 55 pushes the upper inclined rod 51 close to the cement precast board pile until the upper side of the upper inclined rod 51 abuts against the lower end surface of the cement precast board pile. At the same time, the cutter cylinder 531 pushes the telescopic cutter 53 out, and the cutting of the stretch film is completed by the abutment of the telescopic cutter 53 with the lower bottom surface of the cement precast board pile. At this time, the vacuum generator 541 is always connected with compressed air, and negative pressure is generated at the vacuum suction port 54, thereby achieving the adsorption of the cut stretch film.

[0041] After completing the cutting and adsorption of the stretch film, the telescopic cylinder 55 is retracted, thereby achieving the goal of adsorbing the end of the stretch film with the upper inclined rod 51 away from the lower end surface of the cement precast board pile. At this time, the first conveyor belt 2 will continue to transport the cement precast board pile that has completed the winding, and the next cement precast board pile that has not been wound is transported to the avoidance space 21. At this time, the telescopic cylinder 55 pushes the upper inclined rod 51 upward and presses the stretch film against the lower bottom surface of the cement precast board pile. At this time, the swivel 11 rotates. After the swivel 11 rotates several times, the telescopic cylinder 55 retracts the upper inclined rod 51 to prevent the end of the upper inclined rod 51 from being rolled into the stretch film.

[0042] In order to make the rotation of the swivel 11 smoother and limit the rotation of the swivel 11, the gantry 1 is provided with a plurality of limiting rollers 13, the axial direction of the rollers 13 is the same as the axial direction of the swivel 11, the rollers 13 are provided with grooves 131, the width of the grooves 131 is the same as the width of the swivel 11, and the outer edge of the swivel 11 abuts against the bottom of the grooves 131.

[0043] In order to facilitate the removal of the pallet 101, so that the operator can carry and transport the cement precast board pile after the package is completed. The pallet warehouse 4 is located on one side of the end of the first transmission belt, and a discharge port is provided on the bottom of the pallet warehouse 4 near the first conveyor belt 2. A rotating rod 41 is provided inside the pallet warehouse 4. The rotating rod 41 is located on both sides of the discharge port. The rotating rod 41 is located between the first pallet 101 and the second pallet 101 from bottom to top. A lifting plate 411 is provided in the length direction of the rotating rod 41. A first bevel gear 412 is provided on the side of the rotating rod 41 away from the discharge port. A transmission rod 42 corresponding to the rotating rod 41 is provided on the outside of the pallet warehouse 4. The transmission rod 42 is provided with a second bevel gear 421 adapted to the first gear. A pallet motor 43 for driving the transmission rod 42 to rotate is provided on the side of the transmission rod 42 close to each other. The pallet motor 43 and the transmission rod 42 are both provided with a third bevel gear 431 adapted to each other. When the pallet motor 43 rotates, the two rotating rods 41 rotate in opposite directions.

[0044] When it is necessary to take out the pallet 101 in the pallet bin 4, the pallet motor 43 rotates. As the pallet motor 43 rotates, the third bevel gear 431 drives the transmission rod 42 to rotate, and then drives the rotation of the rotating rod 41 through the meshing between the second bevel gear 421 and the first bevel gear 412. In order to achieve different rotation directions of the two rotating rods 41, when installing the second bevel gear 421, the conical surfaces of the two bevel gears should face the same direction. As the rotating rod 41 rotates, the lifting plate 411 on the rotating rod 41 will abut against the lower bottom surface of the second pallet 101 from bottom to top in the pallet bin 4. As the rotating rod 41 rotates further, the lifting plate 411 lifts the second pallet 101 and the pallet 101 above it upwards, and the operator can take out the bottommost pallet 101 from the discharge port. After waiting for the tray 101 to be taken out, the rotating rod 41 rotates in the reverse direction until the lifting plate 411 and the tray 101 are separated from the abutting relationship. At this time, the tray 101 in the tray compartment 4 will fall downward.

[0045] In order to realize the automatic removal of the pallet 101 from the pallet bin 4, a push plate 441 is provided on the side of the pallet bin 4 away from the discharge port, and a push plate cylinder 44 is provided on the frame for pushing the push plate 441 to move, and the push plate 441 is directly opposite to the pallet 101 at the bottom of the pallet bin 4. When the pallet 101 needs to be taken out, the push plate cylinder 44 extends and pushes the push plate 441 to push the pallet 101 to the outside of the discharge port. After the push plate 441 pushes out the lowermost pallet 101, the push plate cylinder 44 contracts and drives the push plate 441 to retract, waiting for the next time when the pallet 101 needs to be pushed out, and repeats the above action again.

[0046] The first conveyor belt 2 includes rollers, and several rollers are provided along the length direction of the conveyor belt. The axis direction of the rollers is perpendicular to the length direction of the conveyor belt. Sprockets are provided at both ends of the rollers, and chains are provided on the outer sides of the sprockets. The first conveyor belt 2 is provided with a first motor for driving the chain to rotate. The second conveyor belt 33 includes a belt. The first conveyor belt 2 and the second conveyor belt 33 are both provided with corresponding driving devices. By using rollers as the first conveyor belt 2, when the cement precast board pile moves on the first conveyor belt 2, the cement debris or other debris above can fall through the gap of the rollers, thereby reducing the accumulation of internal impurities and debris after wrapping. By using a belt as the second conveyor belt 33, the sliding caused by the small friction of the rollers when the rotating base 32 rotates can be effectively prevented, and it can be made to rotate more smoothly with the rotating base 32.

[0047] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
