[0031] Such as Figures 1 to 10As shown in the figure, an embodiment of the present invention provides a die-cutting device for corrugated cardboard production, which is used to cut a raw material board into cardboard 105 and stack the cardboard 105 neatly. The die-cutting device includes a pallet 101, a conveying mechanism, a blowing mechanism, and a positioning mechanism. The pallet 101 is slidably arranged in the vertical direction and is used to hold the cardboard 105. There are two conveying mechanisms. Each conveying mechanism includes a rotating shaft 102, a conveyor belt 103, and a reciprocating component. There are two rotating shafts 102, and the two rotating shafts 102 are arranged in the vertical direction and are located above the pallet 101. The axis direction of each rotating shaft 102 extends along the first direction, and the first direction is the horizontal direction. The conveyor belt 103 is wound around the two rotating shafts 102. The conveyor belts 103 on the two conveying mechanisms are located on both sides of the pallet 101 in the second direction and are used to convey the cardboard 105 between them towards the direction of the pallet 101. The mutually approaching surfaces of the two conveyor belts 103 are vertical surfaces. The second direction is the horizontal direction and is perpendicular to the first direction. A plurality of support rods 104 are respectively arranged on each conveyor belt 103. The plurality of support rods 104 are evenly wound around the circumferential surface of the corresponding conveyor belt 103. The distance between two adjacent support rods 104 on each conveyor belt 103 is greater than the thickness of the cardboard 105, and each support rod 104 penetrates the conveyor belt 103 and is slidably connected to the conveyor belt 103. The support rods 104 on the mutually approaching surfaces of the two conveyor belts 103 correspond one by one. The corresponding two support rods 104 are located on the same horizontal plane, and the corresponding two support rods 104 can support the cardboard 105. The two conveying mechanisms can approach or move away from each other in the second direction. The reciprocating component is used to drive the conveyor belt 103 to slide in the first direction when it moves away from the conveyor belt 103 in the other conveying mechanism. The blowing mechanism is used to blow air on the cardboard 105 on the support rods 104. The positioning mechanism is used to limit the position of the cardboard 105 in the first direction.

[0032] Through the cooperative setting of the conveyor belt 103 and the support rods 104, there is a gap between two adjacent cardboard 105 that move between the conveyor belts 103 and are located on the support rods 104. At the same time, the contact area between the cardboard 105 and external objects is also reduced. When the two conveyor belts 103 approach each other and push the cardboard 105 between them to move, the friction area of the cardboard 105 is small, and there is no friction between two adjacent cardboard 105, reducing the friction loss of the cardboard 105. By setting the blowing mechanism, it can clean the surface of the cardboard 105 between the conveyor belts 103, reduce the residue of debris, and prevent the cardboard 105 from being scratched or punctured after stacking. By setting the reciprocating component, when the conveyor belt 103 pushes and arranges the cardboard 105, it will not only push the sides of the cardboard 105 at the same position, reducing the probability of damage to the same position on the side of the cardboard 105 and improving the product quality.

[0033] In this embodiment, the die-cutting equipment for corrugated board production further includes a housing 100 which is fixedly arranged. The reciprocating assembly includes a bracket 110, a cross plate 111, a support plate 112, a first motor 113 and a first gear 114. The bracket 110 is arranged on the housing 100. The cross plate 111 is slidably arranged on the bracket 110 along a first direction. The support plate 112 is sleeved on the cross plate 111 and is fixedly connected to the cross plate 111. The conveyor belt 103 is wound around the support plate 112. The first motor 113 is fixedly installed on the bracket 110. The first gear 114 is fixedly installed at the output end of the first motor 113. Teeth are provided on the cross plate 111 and extend along the first direction. The first gear 114 meshes with the teeth. The first motor 113 is controlled to start through a control panel. After the conveyor belt 103 moves away from the cardboard 105, the control panel will control the first motor 113 to start. At this time, the pressure of the conveyor belt 103 on the cardboard 105 is relatively small. When the first motor 113 drives the first gear 114 to rotate, the first gear 114 drives the cross plate 111 to move along the first direction through meshing with the cross plate 111. When the conveyor belt 103 approaches the cardboard 105 next time, the contact position between the conveyor belt 103 and the cardboard 105 changes, avoiding repeated extrusion of the same position of the cardboard 105.

[0034] In this embodiment, two rotating shafts 102 penetrate through the support plate 112 along the first direction, and the rotating shafts 102 are rotatably connected to the support plate 112. A second motor is provided on the housing 100. The second motor is connected to the rotating shaft 102 and can drive the rotating shaft 102 to rotate. There are two second motors, and each second motor is correspondingly connected to the rotating shaft 102 in a conveying mechanism. A second gear 123 is sleeved on each rotating shaft 102. The second gear 123 is fixedly connected to the rotating shaft 102. Teeth are provided on the inner surface of the conveyor belt 103. The second gear 123 meshes with the teeth on the conveyor belt 103, making the rotation of the conveyor belt 103 more stable through the meshing method.

[0035] In this embodiment, a groove 122 is formed on the inner surface of the conveyor belt 103. The support rod 104 is slidably connected to the conveyor belt 103, and one end of the support rod 104 is slidably disposed in the groove 122. When the support rod 104 supports the cardboard 105, its axis extends along the first direction. One end of the support rod 104 located in the groove 122 is always slidably connected to the support plate 112. A spring 121 is sleeved on the circumferential surface of the support rod 104. The spring 121 is located in the groove 122. One end of the spring 121 is connected to the conveyor belt 103, and the other end of the spring 121 is connected to the support rod 104. The spring 121 is always in a compressed state. Protrusions 120 are provided on the opposite surfaces of the two support plates 112 in the two conveying mechanisms. The position of each protrusion 120 is adapted to the corresponding groove 122. The support rod 104 can be slidably connected to the corresponding protrusion 120. When the corresponding support rods 104 in the two conveying mechanisms are respectively slidably connected to the corresponding protrusions 120, the distance in the second direction is smaller than the distance of the cardboard 105 in the second direction. The protrusion 120 is disposed in the groove 122. When the conveyor belt 103 drives the support rod 104 to rotate on the support plate 112, when the support rod 104 rotates to the side of the support plate 112 close to the cardboard 105, it slides onto the protrusion 120. The support rod 104 extends out on the conveyor belt 103, and the spring 121 is further compressed. The corresponding two support rods 104 play a role in supporting the cardboard 105.

[0036] In this embodiment, the length of the protrusion 120 in the vertical direction is smaller than the length of the support plate 112 in the vertical direction, and the protrusion 120 is close to the upper end of the support plate 112. The conveyor belt 103 can contact the cardboard 105 stacked on the pallet 101. At this time, the end face of the support rod 104 at the corresponding position of the conveyor belt 103 is flush with the conveyor belt 103. Even if the cardboard 105 stacked on the pallet 101 has a small dislocation, it can still be corrected.

[0037] In this embodiment, air holes 115 penetrating through both end faces of the support rod 104 are provided on the support rod 104; the air blowing mechanism includes a main air pipe 124, an air duct 125 and an air storage tank. The main air pipe 124 is connected to the support plate 112. The air duct 125 is arranged inside the support plate 112. The main air pipe 124 is communicated with the air duct 125. The air duct 125 penetrates through the protrusion 120 and can be communicated with the air holes 115 on the support rod 104. A plurality of air ducts 125 are provided on each support plate 112. When the support rod 104 moves onto an air duct 125, the gas in the air duct 125 can be ejected from the end face of the support rod 104; the air storage tank is arranged on the housing 100 and is communicated with the main air pipe 124. When the support rod 104 slides onto the protrusion 120, the corresponding two support rods 104 can support a cardboard 105. A gap is provided between this cardboard 105 and the adjacent cardboard 105. The gas ejected from the support rod 104 between the two cardboards 105 can clean the surface of the cardboard 105 to avoid residue of sundries. Through the movement of the support plate 112 in the first direction, the range of air blowing on the cardboard 105 by the support rod 104 is larger and the cleaning effect is better.

[0038] In this embodiment, the die-cutting equipment for corrugated cardboard production further includes a die-cutting mechanism. The die-cutting mechanism is used to cut the raw material board and transport the cardboard 105 onto the pallet 101 in the second direction. The position of the cardboard 105 is higher than that of the conveying mechanism. Affected by gravity, the cardboard 105 will fall between the two conveyor belts 103 and will be caught by the support rod 104.

[0039] In this embodiment, the die-cutting equipment for corrugated cardboard production further includes a telescopic rod. Assuming the forward direction of the cardboard 105 is the front, the bracket 110 in the front-side conveying mechanism is slidably arranged on the housing 100 in the first direction. The telescopic rod is fixedly installed on the housing 100 and can telescopically move in the second direction. One end of the telescopic rod is fixedly connected to the front-side bracket 110. The telescopic rod is controlled by a control panel and can drive the corresponding bracket 110 to move. After the bracket 110 moves away from the other bracket 110 in the first direction, the distance between the two support rods 104 corresponding to each other on the two conveying mechanisms and located on the protrusion 120 in the second direction is smaller than the length of the cardboard 105 in the second direction; after the telescopic rod expands and contracts to drive the bracket 110 to approach the other bracket 110 in the first direction, the distance between the two conveyor belts 103 on the two conveying mechanisms is consistent with the length of the cardboard 105 in the second direction.

[0040] In this embodiment, the number of support plates 112 on each conveying mechanism is multiple. The multiple support plates 112 are arranged on the cross plate 111 in sequence in the first direction. The number of conveyor belts 103 is the same as that of the support plates 112. Each conveying mechanism is provided with multiple support plates 112 and multiple conveyor belts 103, which can position the cardboard 105 more accurately when pushing the cardboard 105.

[0041] In this embodiment, there are two positioning mechanisms. Each positioning mechanism includes a fixed rod 126 and a baffle 127. The fixed rod 126 is slidably arranged on the frame along the second direction. The fixed rod 126 extends along the second direction. A bolt is threadedly connected to the frame. The bolt slides on the frame in the radial direction of the fixed rod 126 and can abut against the fixed rod 126 to limit the position of the fixed rod 126 on the frame. The baffle 127 is fixedly installed at one end of the fixed rod 126 close to the pallet 101. The two positioning mechanisms are located on both sides of the pallet 101 in the first direction. The distance between the two baffles 127 is the same as the length of the cardboard 105 on the pallet 101 in the first direction. After the cardboard 105 is cut by the die-cutting mechanism, it is exactly between the two baffles 127. The two baffles 127 can limit the cardboard 105 in the first direction.

[0042] The working principle of a die-cutting device for corrugated cardboard production provided by the above embodiment is as follows:

[0043] First, adjust the distance between the two baffles 127 according to the length of the cardboard 105 in the first direction so that the cardboard 105 will not move in the first direction when it moves onto the conveying mechanism. Then, start the die-cutting mechanism, the first motor 113, the telescopic rod and the second motor, and open the gas storage tank. The cardboard 105 formed after being cut by the die-cutting mechanism approaches the conveying mechanism along the second direction.

[0044] The telescopic rod periodically drives the corresponding bracket 110 to move along the second direction. The bracket 110 drives the corresponding support plate 112 to move through the cross plate 111, and the conveyor belts 103 in the two conveying mechanisms move closer to or away from each other; when the two conveying mechanisms move away from each other, taking one of the conveying mechanisms as an example, the second motor drives the rotating shaft 102 to rotate a preset angle. The rotation of the rotating shaft 102 drives the conveyor belt 103 to rotate through the second gear 123. The rotation of the conveyor belt 103 drives the support rod 104 to move a certain distance. One of the support rods 104 will move onto the corresponding protrusion 120. The protrusion 120 pushes the support rod 104 to compress the spring 121 and slide out of the conveyor belt 103, and this support rod 104 will communicate with the air duct 125. At this time, a cardboard 105 falls onto this support rod 104. Then, the first motor 113 drives the cross plate 111 to move along the first direction through the first gear 114. The cross plate 111 drives the support plate 112 and the conveyor belt 103 to move along the first direction. The support rod 104 moves along the first direction relative to the cardboard 105 on it. At this time, the cardboard 105 is located between the two baffles 127, so the cardboard 105 will not move along the first direction; then the telescopic rod drives the bracket 110 to move in the reverse direction. The bracket 110 drives the cross plate 111 to move in the reverse direction. The cross plate 111 drives the conveyor belt 103 to approach the cardboard 105 through the support plate 112. The conveyor belt 103 abuts against the cardboard 105 and pushes the cardboard 105 to abut against the conveyor belt 103 in the other conveying mechanism; the two first motors 113 and the two second motors in the two conveying mechanisms start and stop synchronously, and the corresponding support rods 104 on the conveyor belts 103 in the two conveying mechanisms can support the same cardboard 105.

[0045] Then, repeat the above actions. The telescopic rod drives the corresponding bracket 110 to move away from the other bracket 110 again. The conveyor belts 103 on the two conveying mechanisms rotate in the same reverse direction synchronously. The support rod 104 in contact with the cardboard 105 moves closer to the tray 101. Then, a new support rod 104 will move onto the corresponding protrusion 120 again, and then another cardboard 105 moves onto this support rod 104. There is a spacing between this cardboard 105 and the previous cardboard 105.

[0046] When the support rod 104 on the protrusion 120 detaches from the protrusion 120, the support rod 104 retracts into the groove 122 under the action of the spring 121. The cardboard 105 supported by the support rod 104 will fall onto the tray 101 at this time. And so on, the cardboard 105 completes the alignment process on the support rod 104, avoiding friction and wear caused by re-alignment after contact.

[0047] When the cardboard 105 is on the support rod 104, the gas in the gas storage tank will be blown out from the air holes 115 through the air duct 125 to clean the surface of the cardboard 105.

[0048] As the cardboard 105 on the pallet 101 is stacked, the pallet 101 moves downward to accommodate the increase in the quantity of the cardboard 105.

[0049] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0050] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
