Description

Technical Field

[0001] The present invention relates to the field of paper box forming equipment, and in particular to an anti-deviating paper box forming equipment. Background Art

[0002] There is a type of biscuit barrel and cake barrel, the barrel body of which is composed of a bottom cardboard and a side cardboard. The middle body of the bottom cardboard is a solid round piece with a serrated edge, and the side cardboard is a ring-shaped penetrating up and down. In the hot pressing production of this type of biscuit barrel and cake barrel, the steps are to first apply a layer of glue on the surface of the serrated area of ​​the bottom cardboard, and then place the ring-shaped side cardboard upright in the middle of the bottom cardboard, align the edge of the side cardboard to the junction of the serrated edge of the bottom cardboard and the main body, and then use a machine to flip up the various tooth structures in the edge area of ​​the bottom cardboard to fit the outer surface of the side cardboard, and through the glue on the tooth structure accompanied by hot pressing, the tooth structure is bonded to the surface of the side cardboard, so that the side cardboard and the bottom cardboard are fixed to each other as a whole, completing the hot pressing of the cylindrical paper box composed of the side cardboard and the bottom cardboard. During the molding process, if the placement position of the side cardboard on the bottom cardboard is offset, not only will the toothed structure on the edge of the bottom cardboard be unable to be completely hot-pressed on the surface of the side cardboard after it is flipped upward, thus destroying the molding effect of the cylindrical carton, but the bottom cardboard will also be unable to be stably connected to the side cardboard, causing the cylindrical carton to loosen and disintegrate. Moreover, during the storage process, the toothed structure of the bottom cardboard may bend upward or downward due to improper storage, resulting in the need for manual reverse bending of the uneven toothed structure in the production process to restore it to its flatness as much as possible to avoid affecting the subsequent gluing operation. However, the long-term upward or downward bending in the storage process has already produced a shaping effect on the toothed structure, and the short-term manual reverse bending has a poor recovery effect, resulting in unstable gluing effect on the surface of the toothed structure. Summary of the Invention

[0003] In order to overcome the shortcomings of, during the hot pressing process of a cylindrical paper box composed of side and bottom paper boards, the offset of the side paper boards will destroy the hot pressing effect, and the deformed tooth structure will lead to unstable surface gluing effect, the present invention provides an anti-offset paper box forming device.

DETAILED DESCRIPTION

[0026] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] An anti-deviation carton forming device, such as Figures 1-10As shown, it includes a mounting frame 1, a fixed platform 2, an annular heater 21, an electric support lifting platform 22, a positioning convex tooth 23, an electric lift 3, a fixed plate 31, a semicircular expansion block 32, a tension spring 33, a wedge-shaped expansion block 34, a first electric push rod 35, an annular frame 4, a second electric push rod 41 and a gluing mechanism; the mounting frame 1 is fixedly connected to the fixed platform 2; the annular heater 21 is installed in the fixed platform 2; the electric support lifting platform 22 is installed on the fixed platform 2, and the lifting support component of the electric support lifting platform 22 is close to the inside of the annular heater 21; a plurality of positioning convex teeth 23 distributed in an annular shape are fixed to the fixed platform 2 for positioning and placing the bottom cardboard 61, the top surface of the positioning convex teeth 23 is higher than the top surface of the annular heater 21, and the height difference between the two is the thickness of the bottom cardboard 61; the mounting frame 1 is installed with an electric lift 3; the lifting component of the electric lift 3 is fixedly connected to the fixed plate 31, and the fixed plate 31 is aligned with the annular heater 2 1 center; two semicircular expansion blocks 32 that are symmetrical to each other are slidably connected to the fixed plate 31; two tension springs 33 are commonly fixed between the two semicircular expansion blocks 32; two wedge-shaped expansion blocks 34 that are symmetrical to each other front and back are slidably connected to the fixed plate 31, and the two wedge-shaped expansion blocks 34 are tightly attached between the two semicircular expansion blocks 32. When the two wedge-shaped expansion blocks 34 respectively push the two semicircular expansion blocks 32 outward, the outer surfaces of the two wedge-shaped expansion blocks 34 in the stretched state and the outer surfaces of the two semicircular expansion blocks 32 together form a complete annular expansion surface; two first electric push rods 35 are installed on the fixed plate 31; the telescopic ends of the two first electric push rods 35 are respectively fixed to a wedge-shaped expansion block 34; an annular frame 4 is slidably connected to the fixed plate 31; two second electric push rods 41 are installed on the fixed plate 31; the telescopic ends of the two second electric push rods 41 are commonly fixed to the annular frame 4; a glue coating mechanism is installed on the annular frame 4.

[0029] The working principle of the hot pressing forming of the anti-deviation paper box forming equipment of this embodiment is as follows.

[0030] First, the staff press Figure 3As shown, the bottom cardboard 61 is placed on the fixed table 2 and the electric support lifting platform 22, the upper surface of the electric support lifting platform 22 is flush with the upper surface of the annular heater 21, and the bottom cardboard 61 is moved and adjusted until each of its tooth structures is respectively stuck between two adjacent positioning protruding teeth 23, and the bottom cardboard 61 is positioned by all the positioning protruding teeth 23. Then, a simple tap is performed to make the bottom cardboard 61 in close contact with the electric support lifting platform 22 and the annular heater 21 of the fixed table 2. The annular heater 21 supports the tooth structure of the bottom cardboard 61 from below, and supports the downwardly bent tooth structure in the bottom cardboard 61 upward and restores it to a horizontal posture. At this time, the upper surface of the bottom cardboard 61 is flush with the upper surface of the positioning protruding teeth 23; the positioning protruding teeth 23 are trapezoidal, but their size, number, and spacing between adjacent positioning protruding teeth 23 and other properties can be determined according to different models of bottom cardboard 61.

[0031] Then place the side cardboard 62 on the upper center of the bottom cardboard 61, and then the electric lift 3 drives the two retracted semicircular expansion blocks 32 and the two retracted wedge-shaped expansion blocks 34 on the fixed plate 31 to be inserted downward into the side cardboard 62. Since the two semicircular expansion blocks 32 and the two wedge-shaped expansion blocks 34 are in the retracted state, the two semicircular expansion blocks 32 and the two wedge-shaped expansion blocks 34 are aligned with the center row of the annular heater 21, and the volume of the two semicircular expansion blocks 32 and the two wedge-shaped expansion blocks 34 is much smaller than the volume of the hollow area in the middle of the side cardboard 62. The two semicircular expansion blocks 32 and the two wedge-shaped expansion blocks 34 can be fully inserted into the hollow area in the middle of the side cardboard 62, and at the same time, the fixed plate 31 drives the annular frame 4 to be sleeved on the side cardboard. 62, and then the two first electric push rods 35 push the two wedge-shaped expansion blocks 34 outward respectively. At the same time, the two wedge-shaped expansion blocks 34 jointly push the two semicircular expansion blocks 32 to move outward and expand. The two semicircular expansion blocks 32 jointly drive the tension spring 33 to stretch. The outer surfaces of the two expanded semicircular expansion blocks 32 and the outer surfaces of the two expanded wedge-shaped expansion blocks 34 together form a complete annular expansion surface. The annular expansion surface will be in complete contact with the entire inner surface of the side cardboard 62 and expand it outward from the inside of the side cardboard 62. The two expanded semicircular expansion blocks 32 and the two expanded wedge-shaped expansion blocks 34 can also move the expanded side cardboard 62 to align with the center area of ​​the bottom cardboard 61, completing the anti-deviation calibration of the side cardboard 62.

[0032] At the same time, the gluing mechanism on the annular frame 4 cooperates with the external glue feeder to perform reciprocating gluing on the edge area surface of the bottom cardboard 61, and applies a layer of glue on the surface of each tooth structure in the edge area of ​​the bottom cardboard 61, thereby realizing the simultaneous gluing work on the edge area surface of the bottom cardboard 61 and the anti-deviation calibration work on the side cardboard 62, thereby optimizing the overall workflow steps and required working time of the hot pressing molding.

[0033] Afterwards, the second electric push rod 41 pulls the annular frame 4 to drive the gluing mechanism to rise up and leave the bottom cardboard 61 that has completed the gluing work. At the same time, the electric lift 3 drives the two semicircular expansion blocks 32 and the two wedge-shaped expansion blocks 34 on the fixed plate 31 to push the bottom cardboard 61 to move downward into the annular heater 21. At the same time, the electric support lifting platform 22 follows the bottom cardboard 61 to move downward. At the same time, the two semicircular expansion blocks 32 and the two wedge-shaped expansion blocks 34 drive the side cardboard 62 expanded on its outer surface to move downward into the annular heater 21. At this time, the tooth-shaped structures in the edge area of ​​the bottom cardboard 61 are restricted by the top of the annular heater 21 and flipped upward to fit closely to the outer surface of the side cardboard 62, and are squeezed into the annular heater 21. The annular heater 21 is between the heater 21 and the semicircular expansion block 32 and the wedge-shaped expansion block 34, and then the annular heater 21 heats the bottom cardboard 61 and the side cardboard 62. The glue layer on the tooth-like structures in the edge area of ​​the bottom cardboard 61 is heated, dried and solidified, so that the tooth-like structures in the edge area of ​​the bottom cardboard 61 are hot-pressed and bonded to the outer surface of the side cardboard 62 by glue. At the same time, the two expanded semicircular expansion blocks 32 and the two expanded wedge-shaped expansion blocks 34 keep expanding the side cardboard 62. The heat from the annular heater 21 can be evenly transferred to the hot pressing area of ​​the side cardboard 62, so that the side cardboard 62 is hot-pressed and shaped into the current complete circular structure, thereby avoiding loosening and disintegration in local areas of the side cardboard 62.

[0034] like Figure 7-Figure 8 As shown, the glue coating mechanism of this embodiment consists of a rotating ring 42, a spur gear ring 43, a motor 44, a spur gear 45, a glue coating roller 46, a bevel gear 47 and a bevel gear ring 48; the rotating ring 42 is rotatably connected to the bottom of the annular frame 4; the spur gear ring 43 is fixedly connected to the side of the rotating ring 42; the motor 44 is mounted on the annular frame 4; the output shaft of the motor 44 is fixedly connected to the spur gear 45; the spur gear 45 is meshed with the spur gear ring 43; the rotating ring 42 is provided with an annular glue storage groove 4201 structure; Two glue delivery pipes 401 connected to the annular glue storage tank 4201 are fixedly connected to the annular frame 4, and the glue delivery pipes 401 are externally connected to the glue delivery machine; a number of glue passage grooves 4202 connected to the annular glue storage tank 4201 are opened on the rotating ring 42; the bottom of each glue passage groove 4202 is rotatably connected to a glue coating roller 46; a bevel gear 47 is fixed to the rotating shaft component of each glue coating roller 46; a bevel gear ring 48 is fixed to the fixed platform 2 and is aligned with all the bevel gears 47 in the upper and lower directions.

[0035] When gluing the edge area of ​​the bottom cardboard 61, the external glue conveyor continuously conveys glue to the annular glue storage tank 4201 of the rotating ring 42 through the glue conveying pipe 401, and the glue in the annular glue storage tank 4201 flows downward to the corresponding glue coating roller 46 through each glue passage groove 4202. At the same time, the motor 44 drives the spur gear 45 to rotate back and forth, and the spur gear 45 engages with the spur gear ring 43 to drive the rotating ring 42 to rotate back and forth. The rotating ring 42 drives the glue coating roller 46 to rotate back and forth along the surface of the edge area of ​​the bottom cardboard 61. At this time, the bevel gear 47 is in a state of meshing with the bevel gear ring 48, so the bevel gear 47 will be driven by the bevel gear ring 48. The bevel gear 47 rotates and drives the glue coating roller 46 to rotate, so that the glue coating roller 46 that rotates back and forth evenly coats the glue on the surfaces of the various tooth structures in the edge area of ​​the bottom cardboard 61 to form a glue layer. Compared with directly rolling the glue coating roller 46 onto the surfaces of the various tooth structures in the edge area of ​​the bottom cardboard 61, the friction between the glue coating roller 46 and the tooth structure surface is used to rotate the glue coating roller 46. The active rotation of the glue coating roller 46 can reduce the friction generated on the surface of the tooth structure, reduce the wear on the surface of the tooth structure and the tearing stress in the connection area between the tooth structure and the main body of the bottom cardboard 61, and avoid the tooth structure from being torn.

[0036] Example 2

[0037] On the basis of Example 1, Figures 1-10 As shown, a plurality of blowing holes 4203 structures are provided at the bottom of the rotating ring 42 of this embodiment; each blowing hole 4203 structure of the rotating ring 42 is connected to an air blowing pipe 5, and the air blowing pipe 5 is externally connected to a blower; the number of the air blowing holes 4203 is twice that of the glue coating roller 46, and each glue coating roller 46 is used in conjunction with two air blowing holes 4203, and the glue coating roller 46 is located between the corresponding two air blowing holes 4203; when the glue coating roller 46 is performing the gluing operation, the external blower blows air to the edge area of ​​the bottom paperboard 61 through the air blowing pipe 5 and the corresponding air blowing holes 4203, and when the toothed structure of the edge area of ​​the bottom paperboard 61 is partially When there is an upward warping phenomenon, the air flow blown out from the blowing hole 4203 can move to the top of the warped tooth structure before the glue coating roller 46, and press the warped tooth structure in the edge area of ​​the bottom cardboard 61 downward to flatten it, so as to prevent the glue coating roller 46 from being blocked and bending the warped tooth structure in the rotation direction when passing through the warped tooth structure in the edge area of ​​the bottom cardboard 61; the position height of the blowing hole 4203 is higher than the bottom height of the glue coating roller 46, so that the blown part of the bottom cardboard 61 will not directly contact the blowing hole 4203, so as to prevent the blowing hole 4203 from blowing away the glue layer due to being too close to the glue layer on the surface of the bottom cardboard 61.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
