Description

Technical Field

[0001] This utility model relates to the field of unpacking, packing and packaging technology, and in particular to a box-supporting device. Background Technology

[0002] Carton openers are essential in the packaging process. Also known as carton board opening devices, the working process of a carton opener is to first open the carton board, then close the bottom cover and convey it to the sealing work area to apply tape to the bottom of the carton.

[0003] Chinese invention patent (CN112193508A) discloses a carton opener, including a frame, a hopper mechanism, a forming mechanism, a carton retrieval mechanism, a conveying mechanism, and a lid closing mechanism. The hopper mechanism, connected to the frame, stores cardboard boards with front and rear panels. The forming mechanism, located on the opposite side of the hopper and slidably connected to the frame, receives cardboard boards conveyed from the carton retrieval mechanism, separates the front and rear panels to form a carton, and holds the carton in place. The carton retrieval mechanism, located above the gap between the hopper mechanism and the forming mechanism and connected to the frame, retrieves cardboard boards from the hopper mechanism and conveys them to the forming mechanism. The lid closing mechanism, located below the gap between the hopper mechanism and the forming mechanism, closes the bottom of the carton. The conveying mechanism, connected to the forming mechanism, conveys paper.

[0004] like Figure 7 As shown, the specific steps for closing the bottom cover of the box 50 are as follows: First, the first panel 501 at the bottom of the box 50 needs to be folded, and then the second panel 502 at the bottom of the box 50 needs to be folded.

[0005] Using the existing carton opener, because there is no mechanism to secure the bottom of the carton 50 before folding, the bottom of the carton 50 cannot be fixed in position before folding, resulting in inaccurate pressing positions. This can cause the bottom crease of the carton to be crushed or torn. Damage to the carton affects its structural integrity, rendering it unusable and causing damage to the contents during transportation. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model discloses a box support device.

[0007] The technical solution adopted in this utility model is as follows:

[0016] In one embodiment of the present invention, the folding bottom mechanism further includes a fourth bracket and connecting plates disposed on both sides of the fourth bracket; the rotating component and the connecting plates are elastically connected.

[0017] In one embodiment of the present invention, the rotating assembly includes a connecting block, an optical axis clamping member fixed on the connecting block, an optical axis axially passing through the optical axis clamping member, a rotating shaft clamping member disposed at both ends of the optical axis, a rotating shaft axially passing through the rotating shaft clamping member, and a folded bottom plate fixedly connected to the rotating shaft; the end of the rotating shaft near the fourth bracket and the connecting plate are connected by an elastic connector.

[0018] In one embodiment of this utility model, the folded bottom plate has a U-shaped clearance groove along its width direction.

[0019] In one embodiment of this utility model, the elastic connecting member is a torsion spring.

[0020] In one embodiment of the present invention, the bottom of the first folding member is provided with a first reinforcing member along its length direction; the bottom of the second folding member is provided with a second reinforcing member along its length direction.

[0022] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0023] The box-supporting device of this utility model first opens and fixes the bottom of the box to its position, then uses the first folding lug assembly and the second folding lug assembly to fold the first panel of the bottom of the box, and finally uses the bottom folding mechanism to fold the second panel of the bottom of the box. This avoids interference from the opening and folding part of the bottom of the box, which would cause damage when the box is folded later. It ensures that it can adapt to boxes of different sizes and improves the pressing accuracy.

[0024] The box support device described in this utility model, when applied to a box opener, can effectively reduce problems that occur when the box opener presses the bottom crease of the carton, thereby improving the reliability and production efficiency of the equipment.

[0043] Combination Figure 1 and Figure 2 A box-supporting device includes a supporting mechanism 10, a first folding lug mechanism 20, a second folding lug mechanism 30, and a bottom-folding mechanism 40.

[0044] Among them, combined Figure 3 The opening mechanism 10 includes a first drive source 102 and a support member 103 connected to the working end of the first drive source 102. The support member 103 is used to open the housing 50. Specifically, the support member 103 includes a linkage plate 1031 and bent plates 1032 arranged at an angle to the linkage plate 1031 and located on both sides of the linkage plate 1031. Preferably, the portion of the bent plate 1032 that connects to the linkage plate 1031 has an oblong hole, so that the bent plate 1032 can be adjusted in the installation position of the linkage plate 1031 to adapt to housings 50 of different specifications.

[0045] Furthermore, the spreading mechanism 10 also includes a first bracket 101. A first drive source 102 is mounted on the first bracket 101. Specifically, the first drive source 102 can be a three-bar cylinder, and the cylinder body of the first drive source 102 is fixed to the first bracket 101 by fasteners such as bolts. Preferably, the installation height of the first drive source 102 is adjustable. Only by opening an oblong hole in the first bracket 101 can the height of the spreading mechanism 10 be adjusted according to the model of the housing 50 by adjusting the height of the first drive source 102.

[0046] Combination Figure 4 The first folding mechanism 20 is located on one side of the spreading mechanism 10. The first folding mechanism 20 includes a second bracket 201, a second drive source 202, and a first folding member 203. The second drive source 202 is located on the second bracket 201. The working end of the second drive source 202 is connected to the first folding member 203, and the first folding member 203 is rotatably connected to the second bracket 201.

[0047] Furthermore, a first reinforcing member 204 is provided at the bottom of the first folding lug 203 along its length. By adding the first reinforcing member 204 at the bottom of the first folding lug 203, stress can be effectively dispersed, stress concentration can be avoided, and damage to the first panel 501 at the bottom of the housing 50 can be reduced by the first folding lug 203.

[0048] Combination Figure 5 The second folding mechanism 30 is located on the other side of the spreading mechanism 10. The second folding mechanism 30 includes a third support 301, a third drive source 302, and a second folding member 303. The third drive source 302 is mounted on the third support 301. The working end of the third drive source 302 is connected to the second folding member 303, and the second folding member 303 and the third support 301 are rotatably connected.

[0049] Furthermore, a second reinforcing member 304 is provided at the bottom of the second folding lug 303 along its length. By adding a second reinforcing member 304 at the bottom of the second folding lug 303, stress can be effectively dispersed, stress concentration can be avoided, and damage to the first panel 501 at the bottom of the housing 50 can be reduced by the second folding lug 303.

[0050] It should be noted that both the first folding mechanism 20 and the second folding mechanism 30 fold the first panel 501 of the housing 50 simultaneously, and the structures of the first folding mechanism 20 and the second folding mechanism 30 are identical. The second drive source 202 and the third drive source 302 are cylinders, and the type of cylinder can be selected and adjusted by those skilled in the art as needed.

[0051] Combination Figure 2 and Figure 6The bottom-folding mechanism 40 is located outside the first folding ear mechanism 20 or the second folding ear mechanism 30. The bottom-folding mechanism 40 includes a fourth support 401, a fourth drive source 402, and a rotating assembly. Connecting plates 409 are provided on both sides of the fourth support 401. The fourth drive source 402 is fixedly connected to the fourth support 401 via a fixing plate 403. The actuating end of the fourth drive source 402 is connected to the rotating assembly. The rotating assembly is located above the support box member 103.

[0052] Specifically, the fourth drive source 402 is a cylinder, and the type of cylinder can be selected and adjusted by those skilled in the art as needed.

[0053] The rotating assembly includes a connecting block, an optical axis clamping member 408 fixed to the connecting block, an optical axis 404 axially passing through the optical axis clamping member 408, a rotating shaft clamping member 407 located at both ends of the optical axis 404, a rotating shaft 405 axially passing through the rotating shaft clamping member 407, and a folded bottom plate 406 fixedly connected to the rotating shaft 405. The end of the rotating shaft 405 near the fourth bracket 401 is connected to the connecting plate 409 via an elastic connector 410.

[0054] Furthermore, the bottom plate 406 has a U-shaped clearance groove along its width. The purpose of the clearance groove is to allow the support box 103, which is lifted by the first drive source 102, to pass.

[0055] The elastic connector 410 is a torsion spring. Specifically, one end of the torsion spring is connected to the rotating shaft 405, and the other end is connected to the connecting plate 409. When the fourth drive source 402 drives the rotating assembly to rise, the position of the connecting plate 409 remains fixed, and the elastic connector 410 generates torque through elastic deformation, driving the rotating shaft 405 to rotate. When the fourth drive source 402 drives the rotating assembly to fall, the position of the connecting plate 409 remains fixed, the elastic connector 410 returns to its original shape, and the rotating shaft 405 also rotates to its initial position.

[0056] Combination Figures 7 to 9 The working principle of this utility model is as follows:

[0057] After the case 50 reaches the designated position, the working end of the first drive source 102 extends, opening the first panel 501 of the case 50. Simultaneously, the working ends of the second drive source 202 of the first folding mechanism 20 and the third drive source 302 of the second folding mechanism 30 extend, and the first folding piece 203 and the second folding piece 303 fold the first panel 501 of the case 50 along the crease line. As the second drive source 202 and the third drive source 302 retract, the working end of the fourth drive source 402 extends, and the elastic connector 410 generates torque through elastic deformation, driving the rotating shaft 405 to rotate. The rotating shaft 405 folds the second panel 502 of the case 50 along the crease line, completing the case opening step of the case opener.
