Description

Technical Field

[0001] The utility model relates to the technical field of carton production, in particular to a flattening machine for producing packing boxes. Background Art

[0002] Corrugated cartons are a widely used type of packing box at present. During the production process of corrugated cartons, they are made into corrugated cartons through die-cutting, indentation, box nailing or gluing. Corrugated cartons are produced by cutting and folding corrugated cardboard. Corrugated cardboard is formed by bonding at least one layer of corrugated paper and one layer of box board paper. After bonding, a flattening device is needed for flattening operations to prevent deformation due to drying shrinkage during the drying process.

[0003] Packing cartons are formed by bonding multiple layers of cardboard. Therefore, after production, the cardboard needs to be flattened. Traditional flattening devices generally directly apply pressure to the cardboard. However, this direct extrusion method is likely to cause the cardboard to directly break due to the relatively high dryness of the cardboard. The patent with the authorization announcement number CN220332152U discloses a flattening device for producing corrugated paper packing boxes. This device forms water droplets on the surface of the cardboard through a wet cleaning part, thereby increasing the humidity of the overall cardboard and reducing the situation of breakage. However, this method can only slightly moisten the surface of the cardboard, and the inside of the cardboard is still dry, resulting in a poor anti-breakage effect. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a flattening machine for producing packing boxes, which solves the problem that in the prior art, flattening devices generally directly apply pressure to the cardboard, but this direct extrusion method is likely to cause the cardboard to directly break due to the relatively high dryness of the cardboard.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A flattening machine for producing packing boxes includes a processing table. A fixed frame is fixedly installed on the top of the processing table. A cylinder is fixedly installed on the surface of the fixed frame. A pressing plate is fixedly installed at the output end port of the cylinder. A groove is formed on the top of the processing table. A supporting plate is arranged inside the groove. A steam box is fixedly installed on the side wall of the processing table where the supporting plate is located. A ring-shaped pipe is communicated with the top of the steam box. The ring-shaped pipe is fixedly installed on the side wall of the processing table. An air outlet groove is formed on the side wall of the ring-shaped pipe close to the processing table. Through holes are evenly formed on the side wall of the processing table at the position corresponding to the ring-shaped pipe.

[0007] Preferably, a supporting plate is arranged inside the groove of the processing table. A second spring is fixedly installed at the bottom of the supporting plate. One end of the second spring away from the supporting plate is fixedly connected with the groove.

[0008] Preferably, ejector rods slidably penetrate through the positions of the surface of the pressing plate near the four corners. A round block is fixedly installed at the top end of the ejector rod. A first spring is sleeved on the surface of the ejector rod. Two ends of the first spring are fixedly connected to the round block and the pressing plate respectively.

[0009] Preferably, the spring constant of the first spring is greater than that of the second spring.

[0010] Preferably, vertical grooves are evenly formed in the inner wall of the processing table, and the vertical grooves are located at the bottom of the annular pipe.

[0011] Preferably, a square groove is formed in the bottom wall of the processing table. A humidity sensor is fixedly installed inside the square groove. A mesh plate is placed on the top of the square groove.

[0012] The utility model has at least the following beneficial effects:

[0013] By arranging the steam box, steam enters into the groove of the processing table through the annular pipe. The steam enters into the groove through the air outlet groove of the annular pipe and the through hole of the processing table. At this time, the steam in the groove contacts with the cardboard, so as to achieve the purpose of wetting the cardboard. Moreover, the steam can enter into the cardboard more fully, further reducing the situation that the cardboard is squeezed and damaged due to drying. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Refer to Figures 1-4, A cardboard box production flattening machine, including a processing table 1, a fixed frame 2 is fixedly installed on the top of the processing table 1, a cylinder 3 is fixedly installed on the surface of the fixed frame 2, a pressing plate 15 is fixedly installed at the output end port of the cylinder 3, a groove is opened on the top of the processing table 1, a support plate 11 is arranged inside the groove, a steam box 4 is fixedly installed on the side wall of the processing table 1 where the support plate 11 is located, a circular pipe 5 is communicated with the top of the steam box 4, the circular pipe 5 is fixedly installed on the side wall of the processing table 1, an air outlet groove is opened on the circular pipe 5 close to the side wall of the processing table 1, and through holes 14 are uniformly opened on the side wall of the processing table 1 at the position corresponding to the circular pipe 5. During use, first place the cardboard to be flattened on the groove of the processing table 1, then start the cylinder 3, the cylinder 3 drives the pressing plate 15 to move downward. After the pressing plate 15 moves into the groove, use the steam box 4 to send steam into the groove of the processing table 1 through the circular pipe 5. The steam enters the inside of the groove through the air outlet groove of the circular pipe 5 and the through holes 14 of the processing table 1. At this time, the steam inside the groove will contact the cardboard, so as to achieve the purpose of wetting the cardboard, and the steam can enter the inside of the cardboard more fully, further reducing the situation that the cardboard is squeezed and damaged due to drying.

[0026] Further, a support plate 11 is arranged inside the groove of the processing table 1, a second spring 12 is fixedly installed at the bottom of the support plate 11, and the end of the second spring 12 away from the support plate 11 is fixedly connected to the groove. By setting the support plate 11, the cardboard is placed on the support plate 11, and the whole support plate 11 is connected by the second spring 12. When the pressing plate 15 squeezes, the whole support plate 11 will move downward into the groove under force, so as to facilitate wetting. After the extrusion is completed, the second spring 12 will move the support plate 11 upward, so as to drive the cardboard upward, facilitating the picking and placing of the cardboard.

[0027] Further, a top rod 7 slidably penetrates through the surface of the pressing plate 15 near the four corners. A round block 6 is fixedly installed at the top end of the top rod 7. A first spring 8 is sleeved on the surface of the top rod 7. The two ends of the first spring 8 are fixedly connected to the round block 6 and the pressing plate 15 respectively. By setting the top rod 7, when the pressing plate 15 moves downward, first use the top rod 7 to contact the support plate 11, and a first spring 8 is arranged at the top of the top rod 7, so as to press the support plate 11 downward by using the top rod 7. Until the pressing plate 15 completely enters the groove, there is a certain space between the support plate 11 and the pressing plate 15 at this time, and the cardboard has not been squeezed at this time. Therefore, in this process, the steam can fully enter the inside of the cardboard, avoiding the phenomenon that the pressing plate 15 moves downward and directly squeezes the cardboard, resulting in the cardboard being deformed by force and the steam not being able to fully contact. When the support plate 11 moves downward to the lowest position, the pressing plate 15 continues to move downward. At this time, the support plate 11 cannot move, and the top rod 7 will move upward relative to the pressing plate 15 until the pressing plate 15 squeezes the cardboard.

[0028] Further, the spring constant of the first spring 8 is greater than that of the second spring 12, so that when the ejector rod 7 presses the supporting plate 11, the second spring 12 will contract first.

[0029] Further, vertical grooves 13 are uniformly formed in the inner wall of the processing table 1, and the vertical grooves 13 are located at the bottom of the annular pipe 5. By providing the vertical grooves 13, when not working, the supporting plate 11 is located above the through hole 14 under the action of the second spring 12. Therefore, the steam coming out of the through hole 14 will be blocked by the supporting plate 11 and restricted inside the groove. When a cardboard is placed on the supporting plate 11, the supporting plate 11 is driven to move downward under the action of the ejector rod 7 until the pressing plate 15 enters the groove. At this time, the supporting plate 11 just moves to below the through hole 14, and the steam coming out of the through hole 14 is just between the supporting plate 11 and the pressing plate 15, facilitating the wetting treatment. The provided vertical grooves 13 can enable the steam at the bottom of the supporting plate 11 to enter between the supporting plate 11 and the pressing plate 15 through the vertical grooves 13 during the downward movement of the supporting plate 11, making full use of the steam.

[0030] Further, a square groove is formed in the bottom wall of the processing table 1, a humidity sensor 9 is fixedly installed inside the square groove, and a mesh plate 10 is placed on the top of the square groove.

[0031] In summary, during use, first place the cardboard to be flattened on the groove of the processing table 1, and then start the cylinder 3. The cylinder 3 drives the pressing plate 15 to move downward. After the pressing plate 15 moves into the groove, use the steam box 4 to introduce steam into the groove of the processing table 1 through the annular pipe 5. The steam enters the inside of the groove through the air outlet groove of the annular pipe 5 and the through hole 14 of the processing table 1. At this time, the steam inside the groove will contact the cardboard, thereby achieving the purpose of moistening the cardboard. Moreover, the steam can enter the inside of the cardboard more fully, further reducing the situation where the cardboard is damaged due to drying and being squeezed. By setting the support plate 11, the cardboard is placed on the support plate 11, and the entire support plate 11 is connected by the second spring 12. When the pressing plate 15 squeezes, the entire support plate 11 will move downward into the groove under force, so as to facilitate moistening. After the extrusion is completed, the second spring 12 will move the support plate 11 upward, thereby driving the cardboard to move upward, facilitating the picking and placing of the cardboard. By setting the ejector rod 7, when the pressing plate 15 moves downward, first use the ejector rod 7 to contact the support plate 11, and the top of the ejector rod 7 is provided with the first spring 8, so as to press the support plate 11 downward by using the ejector rod 7. Until the pressing plate 15 completely enters the groove, there is a certain space between the support plate 11 and the pressing plate 15 at this time, and the cardboard has not been squeezed yet. Therefore, during this process, the steam can fully enter the inside of the cardboard, avoiding the phenomenon that the pressing plate 15 moves downward and directly squeezes the cardboard, resulting in the cardboard being deformed by force and the steam not being able to fully contact. When the support plate 11 moves downward to the lowest position, the pressing plate 15 continues to move downward. At this time, the support plate 11 cannot move, and the ejector rod 7 will move upward relative to the pressing plate 15 until the pressing plate 15 squeezes the cardboard. By setting the vertical groove 13, when not working, the support plate 11 is above the through hole 14 under the action of the second spring 12. Therefore, the steam coming out of the through hole 14 will be blocked by the support plate 11 and restricted inside the groove. When there is cardboard on the support plate 11, the ejector rod 7 drives the support plate 11 to move downward until the pressing plate 15 enters the groove. At this time, the support plate 11 just moves below the through hole 14, and the steam coming out of the through hole 14 is just between the support plate 11 and the pressing plate 15, facilitating the moistening treatment. The set vertical groove 13 can enable the steam at the bottom of the support plate 11 to enter between the support plate 11 and the pressing plate 15 through the vertical groove 13 during the process of the support plate 11 moving downward, making full use of the steam.
