Description

Technical Field

[0001] An embodiment of the present application relates to a paper box folding fixture. Background Art

[0002] Paper boxes and cartons are made of corrugated cardboard, which has a very high cost-effectiveness and is widely used in product packaging and express packaging. However, its folding is more troublesome and usually needs to be done manually, resulting in low production efficiency and high cost.

[0003] The existing folding auxiliary clamp has the following problems:

[0004] The existing airplane box folding fixture does not have the function of correcting the placement of the cardboard. When the placement of the cardboard on the fixture is offset, the bottom plate of the box may be damaged during the folding process, resulting in the overall appearance of the box being damaged and unsightly. Secondly, the existing box folding fixture does not have the function of limiting the position of the cardboard. When the cardboard is initially positioned in the fixture, when the user releases his hand to proceed to the next step, the cardboard will pop out from the initial position due to its own toughness. Further pressing will cause the position to shift, requiring further correction before proceeding to the next step. Otherwise, the appearance of the box will be damaged. In addition, during the folding process of a box with a swing cover, the swing cover needs to be folded on the inner side of the side wing. During the folding process, the end of the swing cover is prone to conflict with the side wing, resulting in an unsmooth folding process and affecting the folding efficiency. Utility Model Content

As used herein, the terms "first", "second", and "third", etc. are used interchangeably to distinguish one component from another and are not intended to indicate the location or importance of individual components.

[0033] like Figures 1 to 6 As shown, according to an embodiment of the present application, a paper box folding clamp is provided, including a base, on which a clamp assembly is arranged, and a clamping area 100 is formed between the clamp assemblies. When in use, the cardboard to be folded is placed in the clamping area 100, and with the support and guidance of the clamp assembly, the user can fold the cardboard into a paper box more conveniently and efficiently.

[0034] The clamp assembly includes two first support members 7 and two second support members 8, wherein the two first support members 7 are arranged on one side of the base, and the two second support members 8 are arranged on the other side of the base, and the first support members 7 and the second support members 8 are respectively connected to the base, and a quadrilateral clamping area 100 is formed between the two first support members 7 and the two second support members 8, and when the cardboard to be folded is placed above the clamping area 100, the side wing 26 of the folded cardboard is located between the first support member 7 and the second support member 8. Among them, the two first support members 7 are respectively provided with a guide surface 71 on the side surface opposite to the corresponding second support member 8, and the guide surface 71 is an inclined plane or an arc surface transitioning from the upper end to the lower end, so that when the end of the side wing 26 moves from the upper end to the lower end along the guide surface 71, the end of the side wing 26 is closer to the middle of the clamping area 100. By providing the guide surface 71 , when the bottom plate 21 is pressed downward during folding of the paper box, the position of the paperboard can be corrected into the clamping area 100 , thereby preventing the bottom plate 21 from being damaged due to the position deviation of the paperboard in the clamping area 100 .

[0035] In some embodiments, the base is a slide rail base, and the clamp assembly is slidably connected to the slide rail base. The size of the clamping area 100 is adjusted by adjusting the size of the quadrilateral formed in the middle of the slide rail base and the position of the clamp assembly on the slide rail base, thereby achieving auxiliary folding to adapt to paper boxes of various sizes.

[0036] In some embodiments, the slide rail base includes two mutually parallel first slide rails 1 and two mutually parallel second slide rails 2, the two first slide rails 1 and the two second slide rails 2 are respectively located in the upper and lower surfaces and are vertically cross-distributed, and a slider is respectively provided at each intersection of the first slide rail 1 and the second slide rail 2, and each slider at its intersection is respectively slidably connected with the corresponding first slide rail 1 and the second slide rail 2, and the slider can selectively fix its position on the corresponding first slide rail 1 and the second slide rail 2. By adjusting the positions of the four sliders on the corresponding first slide rail 1 and the second slide rail 2, the size change of the quadrilateral surrounded by the first slide rail 1 and the second slide rail 2 can be adjusted to form a two-dimensional sliding platform. The two first support members 7 are respectively movably assembled with the two first slide rails 1, and the two second support members 8 are movably assembled with the second slide rail 2 away from the first support member 7 through the corresponding sliders. When the size of the quadrilateral surrounded by the first slide rail 1 and the second slide rail 2 changes, the first support member 7 and the second support member 8 are respectively adjusted to the position, which is suitable for auxiliary folding of cartons of different sizes.

[0037] In some embodiments, the four sliders include two first bottom plates 3 and two second bottom plates 4, the two first bottom plates 3 are located above the same second slide rail 2 and respectively below two different first slide rails 1, and the two second bottom plates 4 are located above another second slide rail 2 and respectively below two different first slide rails 1. The two second support members 8 are fixedly connected to the two bottom plates 3, respectively, so that the second support members 8 and the second slide rails 2 can be movably assembled.

[0038] In some embodiments, the first slide rail 1 and the second slide rail 2 are respectively connected to the first base plate 3 and the second base plate 4 by bolts. When the bolts are loosened, the first base plate 3 and the second base plate 4 can move on the corresponding first slide rail 1 and the second slide rail 2. When the bolts are tightened, the positions of the first base plate 3, the second base plate 4 and the first slide rail 1 and the second slide rail 2 are fixed to form a stable base.

[0039] In some embodiments, the ends of the two first support members 7 away from the second bottom plate 4 are respectively vertically connected to the swing cover guide assembly 6, and the swing cover guide assembly 6 includes a guide rail 60, and the bottom surface and one of the side surfaces of the guide rail 60 are respectively provided with a first slide groove 601 and a second slide groove 602. A guide member 61 is movably sleeved on the guide rail 60, and a first bolt 611 is provided at the bottom of the guide member 61. When the end of the first bolt 611 passes through the bottom of the guide member 61 and abuts against the bottom of the first slide groove 601, the guide member 61 and the guide rail 60 can be relatively fixed. The opposite side of the two guide rails 60 and the opposite side of the two guide members 61 are respectively provided with arc surfaces for supporting and guiding the first swing cover 24. When the guide rail 60 and the guide member 61 are relatively extended, they can conveniently adapt to the support and guidance of the first swing cover 24 of different sizes.

[0040] In some embodiments, a limiting member 62 is installed on the top of the guide member 61 for limiting the position of the paperboard before folding. A second bolt 621 is arranged on the side of the limiting member 62, and the end of the second bolt 621 passes through the side of the limiting member 62 and abuts against the bottom of the second slide groove 602 to fix the limiting member 62 and the guide rail 60 relatively.

[0041] In some embodiments, a third slide groove 72 is provided on the upper surface of the first support member 7, and a first limit strip 612 is provided at the bottom of the guide member 61. The first limit strip 612 can slide in the third slide groove 72. When the first limit strip 612 moves to one end of the third slide groove 72 close to the guide surface 71, the end of the guide member 61 protrudes from the upper end of the guide surface 71, shortening the distance between the end of the guide member 61 and the clamping area 100, which is used to solve the problem that the guide member 61 has poor support effect on the soft cardboard rocking cover 24 when the soft cardboard is folded.

[0042] In some embodiments, both first slide rails 1 are movably connected with a support rod 5 , one end of the support rod 5 is slidably connected to the first slide rail 1 , and the other end is connected to the end of the guide rail 60 away from the first support member 7 for supporting the guide rail 60 .

[0043] In some embodiments, an additional block 63 is detachably mounted on the limiting member 62. After the additional block 63 is installed, the height of the limiting member 62 can be increased, which is suitable for folding paper boxes of different sizes.

[0044] In some embodiments, a limiting groove 622 and a first connecting hole 623 are provided on the upper surface of the limiting member 62, a second limiting strip 631 is provided on the lower surface of the additional block 63 corresponding to the limiting groove 622, and a second connecting hole 632 is provided on the additional block 63 corresponding to the first connecting hole 623, which passes through from top to bottom. When the additional block 63 is connected to the limiting member 62, the second limiting strip 631 is installed in the limiting groove 622, and screws or pins are provided in the first connecting hole 623 and the second connecting hole 632, so as to realize the limiting installation of the additional block 63 on the limiting member 62.

[0045] In some embodiments, the two second slide rails 2 are respectively movably connected with third support members 9 in the clamping area 100. The two third support members 9 are respectively located between the two first support members 7 and between the two second support members 8, and are respectively used for supporting and guiding the bottom plate rear support plate 22 and the bottom plate front support plate 23 of the paper box. At least one third support member 9 is respectively movably connected between the two first support members 7 and the two second support members 8. When the size of the box to be folded is large, multiple third support members 9 can be added to improve the support effect. At least one fourth support member 10 is movably connected to the two first slide rails 1 in the clamping area 100. The two fourth support members 10 are respectively located between the first support member 7 and the second support member 8 on the two first slide rails 1, and are used for supporting and guiding the side wings 26. Multiple fourth support members 10 can be selectively connected to a single first slide rail 1 to adapt to the support and guidance of boxes of different sizes when folding, thereby improving the support effect.

[0046] In some embodiments, a first support guide surface 91 is provided at the upper end of the third support member 9 between the two second support members 8, and a second support guide surface 92 is provided at the upper end of the third support member 9 between the two first support members 7, and the first support guide surface 91 and the second support guide surface 92 are oriented oppositely.

[0047] In some embodiments, the first support guide surface 91 and the second support guide surface 92 are inclined planes or arc surfaces, and the angle between the second support guide surface 92 and the horizontal plane is smaller than the angle between the first support guide surface 91 and the horizontal plane, so that when the cardboard is placed in the clamping area 100, the second support guide surface 92 better supports the bottom plate front support plate 23 and can reduce the pressure between the second support guide surface 92 and the bottom plate front support plate 23.

[0048] In some embodiments, the third support member 9 and the fourth support member 10 are respectively provided with guide wheels on one side close to the clamping area 100 to improve the guiding ability of the support members to the paperboard.

[0049] In some embodiments, the guide member 61 and the second support member 8 are both higher than the third support member 9 and the fourth support member 10 . When the bottom plate 21 is pressed down, the first swing cover 24 and the second swing cover 25 are folded before the side wings 26 .

[0050] In some embodiments, the third support member 9 is higher than the fourth support member 10 , so that in the first stage of the folding process, the bottom plate rear support plate 22 and the bottom plate front support plate 23 are bent before the two side wings 26 under the support of the third support member 9 .

[0051] In some embodiments, the guide wheel on the third support member 9 between the two first support members 7 is the first guide wheel 16, the guide wheel on the fourth support member 10 is the second guide wheel 17, and the guide wheel on the third support member 9 between the two second support members 8 is the third guide wheel 18, wherein the second guide wheel 17 contacts the paper box before the first guide wheel 16, and when the bottom plate 21 is further pressed downward, the side wings 26 of the paper box are folded into place before the front support plate 23 of the bottom plate.

[0052] In some embodiments, the diameters of the first guide wheel 16, the second guide wheel 17, and the third guide wheel 18 are the same, and the installation heights of the axes of the first guide wheel 16, the second guide wheel 17, and the third guide wheel 18 are increased in sequence. When the bottom plate 21 is further pressed downward, since the height of the second guide wheel 17 is higher than the first guide wheel 16, the side wing 26 will be folded into place before the bottom plate front support plate 23, reducing the conflict between the end of the first swing cover 24 and the plate surface of the side wing 26 during the folding process, making the folding process smoother. In addition, since the height of the third guide wheel 18 is higher than the second guide wheel 17, and the second guide wheel 17 is higher than the first guide wheel 16, the folding order of the bottom plate rear support plate 22, the side wing 26, and the bottom plate front support plate 23 is different during the folding process, so that the bottom plate rear support plate 22, the side wing 26, and the bottom plate front support plate 23 apply force to the bottom plate 21 in stages. Compared with the synchronous folding process, this folding method is smoother and has higher folding efficiency.

[0053] In some embodiments, the axis installation heights of the first guide wheel 16, the second guide wheel 17, and the third guide wheel 18 are the same and their diameters increase sequentially, which can also achieve different folding sequences of the above-mentioned bottom plate rear support plate 22, side wings 26, and bottom plate front support plate 23.

[0054] When folding the carton, Figure 8 , 9 When the paper box shown is placed on the folding auxiliary clamp, the bottom plate 21 of the box body is located above the clamping area 100, the bottom plate rear support plate 22 and the bottom plate front support plate 23 are respectively abutted against the first support guide surface 91 and the second support guide surface 92, the second rocker covers 25 on both sides of the bottom plate rear support plate 22 are respectively abutted against the two second support members 8, the first rocker covers 24 on both sides of the bottom plate front support plate 23 are respectively abutted against the two guide members 61, the side wings 26 on both sides of the bottom plate 21 are respectively abutted against the corresponding fourth support members 10, and the ends of the two side wings 26 close to the first rocker covers 24 are abutted against the guide surface 71 of the first support member 7, specifically, the part of the side wing 26 located between the bottom plate 21 and the side wing fold line 261 is abutted against the fourth support member 10.

[0055] When folding, firstly, the preliminary downward positioning is performed, so that the two side wings 26 move downward along the guide surface 71 near the end of the first swing cover 24, so that the position of the paperboard is corrected, so as to facilitate the further folding operation to be accurate in position. And because the guide member 61 and the second support member 8 are both higher than the third support member 9 and the fourth support member 10, when the carton board is placed on the folding auxiliary fixture, the first swing cover 24 and the second swing cover 25 are bent before the bottom plate rear support plate 22 and the bottom plate front support plate 23, respectively. Then, further downward pressing is performed, because the third support member 9 is higher than the fourth support member 10, the bottom plate rear support plate 22 and the bottom plate front support plate 23 are bent before the side wings 26, and the first swing cover 24 and the second swing cover 25 are respectively located on the inner side of the side wings 26. Then, further downward pressing is performed, because the height of the second guide wheel 17 is higher than the first guide wheel 16, the side wings 26 will be folded into place before the bottom plate front support plate 23 during the further downward pressing process. When the bottom plate 21 is pressed down to the right position, the bottom plate rear support plate 22 and the bottom plate front support plate 23 are bent to be perpendicular to the bottom plate 21, the first swing cover 24 and the second swing cover 25 are respectively perpendicular to the bottom plate rear support plate 22, the bottom plate front support plate 23 and the bottom plate 21, the side wings 26 are perpendicular to the bottom plate 21 and the side wings 26 respectively surround the first swing cover 24 and the second swing cover 25 inside, then the side wings 26 are folded along the side wing fold lines 261 and the snap-on keys 262 are inserted into the snap-on grooves 263, so that the first swing cover 24 and the second swing cover 25 are clamped in the corresponding side wings 26. At this time, the part of the box body excluding the box cover is folded.

[0056] In some embodiments, a fixing seat 11 is provided on the second slide rail 2 near the second support member 8, and the fixing seat 11 and the first bottom plate 3 are slidably connected to the second slide rail 2 through bolts. A guide surface is provided on the side of the fixing seat 11 near the clamping area 100, and a third guide wheel 18 is also installed on this side, and the axis installation height of the third guide wheel 18 on the fixing seat 11 is the same as the axis installation height of the third guide wheel 18 on the third support member 9, which is used to further enhance the guiding and supporting effect on the bottom plate rear support plate 22.

[0057] In some embodiments, the end of the fixing seat 11 away from the second slide rail 2 is movably connected to the fifth support member 13, and the two first bottom plates 3 are respectively provided with an adjusting screw 12, and the end of the adjusting screw 12 away from the first bottom plate 3 is in contact with the fifth support member 13, and the end of the adjusting screw 12 away from the first bottom plate 3 can be adjusted upward or downward relative to the first bottom plate 3, so as to adjust the angle between the fifth support member 13 and the fixing seat 11. Figure 7 When the carton board is placed on the folding auxiliary fixture, its top cover abuts against the fifth support member 13. When the fixing seat 11 adjusts its position relative to the second slide rail 2 along with the corresponding first bottom plate 3, the fifth support member 13 supports top covers 27 of different sizes.

[0058] In some embodiments, the fifth support member 13 is hinged to the fixing seat 11 through a connecting member 14. One end of the connecting member 14 is provided with a clearance groove 141 with an open end, the hinged end of the fixing seat 11 is placed in the clearance groove 141 and is hinged to the connecting member 14, and the other end of the connecting member 14 is fixedly connected to the fifth support member 13. By providing the connecting member 14, the center line of the fifth support member 13 and the fixing seat 11 can be in a straight line, which facilitates the folding and storage of the fifth support member 13 into the clamping area 100 and avoids collision with other support members.

[0059] In some embodiments, a stopper block 15 is slidably connected to the fifth support member 13, and the stopper block 15 is fixed to the fifth support member 13 by bolts. When in use, the position of the stopper block 15 can be adjusted after the bolts are loosened, and then the bolts are tightened to fix the stopper block 15 to the fifth support member 13, so as to adapt to the limit stop of the top cover 27 of paper boxes of different sizes. After the stopper block 15 is set, the end of the top cover support plate 28 of the paperboard to be folded abuts against the stopper block 15, so that the paperboard can be limited in the clamp assembly during the initial positioning, and the phenomenon that some relatively hard paperboards pop outward due to the elasticity of the paperboard itself when initially pressed down for positioning can be avoided, which is convenient for initially limiting the paperboard and improving the efficiency of paper box folding.

[0060] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0061] 1. A guide surface is provided on a side surface of the first support member 7 close to the inner side of the clamping area 100, so that the position of the cardboard can be corrected into the clamping area during the initial downward pressing process of the cardboard to prevent the bottom plate from being damaged due to the position deviation of the cardboard.

[0062] 2. A swing cover guide assembly 6 is disposed on the first support member 7 , and a curved surface is disposed on one side of the swing cover guide assembly 6 close to the inside of the clamping area 100 for supporting and guiding the first swing cover 24 .

[0063] 3. A third slide groove 72 is provided on the first support member 7, and a first limit strip 612 is provided at the bottom of the swing cover guide assembly 6. The first limit strip 612 is in the third slide groove 72. The first limit strip 612 slides in the third slide groove 72 to achieve a limited movable connection between the swing cover guide assembly 6 and the first support member 7.

[0064] 4. At least one third support member 9 is respectively provided on two opposite side edges of the base, which is used to support and guide the bottom plate rear support plate 22 and the bottom plate front support plate 23 of the paper box. At least one fourth support member 10 is respectively provided on the other two opposite side edges, which is used to support and guide the side wings on both sides of the paper box. The third support member 9 is higher than the fourth support member 10. During the folding process, the bottom plate rear support plate 22 and the bottom plate front support plate 23 are bent before the two side wings 26 under the support of the third support member 9.

[0065] 5. The third support member 9 and the fourth support member 10 between the two first support members are respectively provided with a first guide wheel 16 and a second guide wheel 17 on one side close to the clamping area 100, so as to improve the guiding ability of the support members to the cardboard, and the installation height of the axis of the first guide wheel 16 is lower than the installation height of the axis of the second guide wheel 17. When the bottom plate 21 is further pressed downward, the side wing 26 will be folded into place before the front support plate 23 of the bottom plate, thereby reducing the conflict between the end of the first swing cover 24 and the plate surface of the side wing 26 during the folding process, making the folding process smoother.

[0066] 6. At least one fixed seat 11 is arranged between the two second support members 8 on the base, a fifth support member 13 is hinged on the fixed seat 11, and a stop block 15 is movably connected to the fifth support member 13, so as to avoid the phenomenon that some harder cardboards pop outwards due to the elasticity of the cardboards themselves when they are initially pressed down for positioning, thereby facilitating the initial positioning of the cardboards and improving the efficiency of folding the paper boxes.

[0067] 7. The base is a two-dimensional slide rail base, which can change the size of the quadrilateral formed between the first and second slide rails by adjusting the positions of the four sliders on the corresponding first and second slide rails, making it convenient for auxiliary folding of cartons of different sizes.

[0068] Compared with the prior art, the paper box folding auxiliary clamp of the embodiment of the present application has a position correction function and a limiting function, which makes the folding process smoother, reduces the paper box damage rate, and improves the paper box folding efficiency.

[0069] The above descriptions are only some embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
