[0022] By the coordinated arrangement of the conveyor belt 103 and the support rod 104, a distance is provided between two adjacent cardboards 105 that move between the conveyor belts 103 and are located on the support rod 104, and at the same time, the contact area between the cardboard 105 and external objects is reduced. When the two conveyor belts 103 approach each other and push the cardboard 105 therebetween to move, the friction area of ​​the cardboard 105 is small, and there is no friction between the two adjacent cardboards 105, thereby reducing the friction loss of the cardboard 105; an air blowing mechanism is provided to clean the surface of the cardboard 105 between the conveyor belts 103, reduce the residue of debris, and prevent the cardboards 105 from being scratched or punctured after being stacked; a reciprocating component is provided, and when the conveyor belt 103 pushes and aligns the cardboards 105, it will not only push the sides of the cardboards 105 at the same position, thereby reducing the probability of damage to the same position of the side of the cardboard 105, thereby improving product quality.

[0023] In this embodiment, the die-cutting equipment for corrugated cardboard production also includes a shell 100, which is fixedly arranged. The reciprocating component 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 shell 100, the cross plate 111 is slidably arranged on the bracket 110 along the first direction, the support plate 112 is sleeved on the cross plate 111, and the support plate 112 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, the cross plate 111 is provided with teeth, the teeth extend along the first direction, and the first gear 114 is meshed with the teeth.

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 in the first direction by engaging 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, so as to avoid repeated squeezing of the same position of the cardboard 105.

[0024] In this embodiment, two rotating shafts 102 penetrate 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 shell 100, and the second motor is connected to the rotating shaft 102. The second motor can drive the rotating shaft 102 to rotate.

Teeth are provided on the inner surface of the conveyor belt 103, and the second gear 123 meshes with the teeth on the conveyor belt 103, so that the rotation of the conveyor belt 103 is more stable through meshing.

[0025] In this embodiment, a groove 122 is provided 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 set in the groove 122. When the support rod 104 supports the paperboard 105, its axis extends along the first direction, and 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 circumference of the support rod 104, and 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. The two support plates 112 in the two conveying mechanisms are provided with protrusions 120 on the opposite sides. The position of each protrusion 120 is matched with the corresponding groove 122, and the support rod 104 can be slidably connected with the corresponding protrusion 120. When the corresponding support rods 104 in the two conveying mechanisms are slidably connected with the corresponding protrusions 120, the spacing in the second direction is smaller than the spacing in the second direction of the cardboard 105. The protrusion 120 is arranged in the groove 122, and when the conveyor belt 103 drives the support rod 104 to rotate on the support plate 112, the support rod 104 slides onto the protrusion 120 when it rotates to the side of the support plate 112 close to the cardboard 105, and the support rod 104 extends out on the conveyor belt 103, the spring 121 is further compressed, and the corresponding two support rods 104 support the cardboard 105.

[0026] 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, and at this time, the end surface of the support rod 104 at the corresponding position of the conveyor belt 103 is flush with the conveyor belt 103, and the cardboard 105 stacked on the pallet 101 can still be corrected even if a small misalignment occurs.

[0027] In this embodiment, the support rod 104 is provided with air holes 115 penetrating its two end surfaces; the blowing mechanism includes a main air pipe 124, an air channel 125 and an air storage tank, the main air pipe 124 is connected to the support plate 112, the air channel 125 is arranged in the support plate 112, the main air pipe 124 is communicated with the air channel 125, the air channel 125 penetrates the protrusion 120 and can be communicated with the air hole 115 on the support rod 104, each support plate 112 is provided with a plurality of air channels 125, when the support rod 104 moves to an air channel 125, the gas in the air channel 125 can be blown out from the support rod 104, 4; the gas storage tank is arranged on the shell 100, and the gas storage tank is connected with the main gas pipe 124. When the support rod 104 slides onto the protrusion 120, the corresponding two support rods 104 can support a cardboard 105, and a gap is provided between the cardboard 105 and the adjacent cardboard 105. The gas sprayed by the support rod 104 between the two cardboards 105 can clean the surface of the cardboard 105 to avoid residual debris. By moving the support plate 112 along the first direction, the support rod 104 has a larger range of blowing air on the cardboard 105, and the cleaning effect is better.

[0028] In this embodiment, the die-cutting equipment for corrugated cardboard production also includes a die-cutting mechanism, which is used to cut the raw material board and transport the cardboard 105 to the pallet 101 along the second direction. The position of the cardboard 105 is higher than the conveying mechanism. The cardboard 105 will fall between the two conveyor belts 103 due to gravity and will be caught by the support rod 104.

[0029] In this embodiment, the die-cutting equipment for corrugated cardboard production also includes a telescopic rod. Assuming that the direction in which the cardboard 105 moves forward is forward, the bracket 110 in the conveying mechanism located on the front side is slidably arranged on the shell 100 along the first direction, and the telescopic rod is fixedly installed on the shell 100. The telescopic rod is telescopic along the second direction, and one end of the telescopic rod is fixedly connected to the bracket 110 located on the front side. The telescopic rod is controlled by the control panel, and the telescopic rod can drive the corresponding bracket 110 to move. After the bracket 110 moves away from the other bracket 110 along the first direction, the spacing between the two support rods 104 on the two conveying mechanisms that correspond to each other and are located on the protrusion 120 in the second direction is less than the length of the cardboard 105 in the second direction; after the telescopic rod is telescopically extended to drive the bracket 110 to approach the other bracket 110 along 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.

[0030] In this embodiment, there are multiple support plates 112 on each conveying mechanism, and the multiple support plates 112 are arranged on the cross plate 111 in sequence along the first direction. The number of conveyor belts 103 is consistent with the number of support plates 112. Each conveying mechanism is provided with multiple support plates 112 and multiple conveyor belts 103, so that the positioning of the cardboard 105 is more accurate when pushing the cardboard 105.

[0031] In this embodiment, two positioning mechanisms are provided, each positioning mechanism includes a fixing rod 126 and a baffle 127, the fixing rod 126 is slidably arranged on the frame along the second direction, the fixing rod 126 extends along the second direction, a bolt is threadedly connected to the frame, the bolt slides on the frame along the radial direction of the fixing rod 126 and can abut against the fixing rod 126, so as to limit the position of the fixing rod 126 on the frame; the baffle 127 is fixedly installed on one end of the fixing rod 126 close to the support plate 101; the two positioning mechanisms are located on both sides of the support plate 101 in the first direction, the distance between the two baffles 127 is consistent with the length of the cardboard 105 on the support plate 101 in the first direction, and after the cardboard 105 is cut by the die-cutting mechanism, it is located between the two baffles 127, and the two baffles 127 can limit the cardboard 105 in the first direction.

[0032] The working principle of the die-cutting equipment for corrugated cardboard production provided in the above embodiment is as follows: First, the distance between the two baffles 127 is adjusted according to the length of the cardboard 105 in the first direction, so that the cardboard 105 will not move along the first direction when it moves to the conveying mechanism. Then, the die-cutting mechanism, the first motor 113, the telescopic rod and the second motor are started, and the gas tank is opened. The cardboard 105 formed by cutting by the die-cutting mechanism approaches the conveying mechanism along the second direction.

[0033] The telescopic rod periodically drives the corresponding bracket 110 to move along the second direction, and 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 approach or move 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, and the rotating shaft 102 rotates to drive the conveyor belt 103 to rotate through the second gear 123, and the conveyor belt 103 rotates to drive the support rod 104 to move a certain distance, and one of the support rods 104 will move to the corresponding protrusion 120, and the protrusion 120 pushes the support rod 104 to compress the spring 121 to slide out of the conveyor belt 103, and the support rod 104 will be connected to the airway 125, at this time, a cardboard 105 falls on the support rod 104, and then the first motor 113 drives the first gear 114 to drive The movable cross plate 111 moves along the first direction, the cross plate 111 drives the support plate 112 and the conveyor belt 103 to move along the first direction, and the support rod 104 moves along the first direction relative to the cardboard 105 thereon. At this time, the cardboard 105 is located between the two baffles 127, so the cardboard 105 does not move along the first direction; then the telescopic rod drives the bracket 110 to move in the opposite direction, and the bracket 110 drives the cross plate 111 to move in the opposite direction, and the cross plate 111 drives the conveyor belt 103 to approach the cardboard 105 through the support plate 112, and 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 are started and stopped synchronously, and the corresponding support rods 104 on the conveyor belts 103 in the two conveying mechanisms can support the same cardboard 105.

[0034] Then repeat the above action, the telescopic rod drives the corresponding bracket 110 away from the other bracket 110 again, the conveyor belts 103 on the two conveying mechanisms rotate synchronously in opposite directions, and the support rod 104 abutting against the cardboard 105 approaches the support plate 101, and then a new support rod 104 moves to the corresponding protrusion 120 again, and then another cardboard 105 moves to the support rod 104, and there is a distance between the cardboard 105 and the previous cardboard 105.

[0035] When the support rod 104 on the protrusion 120 is detached from the protrusion 120, the support rod 104 retracts into the groove 122 under the action of the spring 121, and the cardboard 105 supported by the support rod 104 will fall onto the support plate 101. Similarly, the cardboard 105 completes the alignment process on the support rod 104, avoiding friction and wear caused by alignment after contact.

[0036] When the paperboard 105 is on the support rod 104 , the gas in the gas storage tank will be blown out from the air hole 115 through the air channel 125 to clean the surface of the paperboard 105 .

[0037] As the cardboards 105 on the pallet 101 are stacked, the pallet 101 moves downward to accommodate the increase in the number of cardboards 105 .

[0038] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, 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, they should be considered to be within the scope of this specification.

[0039] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
