Description

Technical Field

[0001] The present application belongs to the field of packaging processing technology, and more specifically, relates to a capping device and packaging equipment. Background Art

[0002] In most processing and production fields, in order to improve production efficiency, it is necessary to use automated production equipment. The last step in processing and production is basically product packaging.

[0003] The box used for packaging generally includes four side walls and four hinges. The four side walls enclose a cavity with an opening. The cavity can accommodate products. The hinges are arranged on the side walls and can be folded toward the opening of the cavity to cover the opening of the cavity. After the product is placed in the cavity of the box, two of the hinges facing each other need to be folded toward the opening of the cavity, and then glue is applied on the surface of the hinge away from the bottom of the box. Then, the other two hinges facing each other are folded toward the opening of the cavity, so that the other two hinges and the hinges with glue on the surface are fitted to seal the opening of the cavity. The box then flows to the next station. During the transportation process, the glue is not solidified, which will cause the hinges to not fit together and the opening of the cavity to be unsealed.

[0039] See also Figure 1 and Figure 2The capping device provided in the embodiment of the present application is now described. The capping device provided in the embodiment of the present application comprises a bracket 1, a rotating connecting rod assembly 2 and an angle control connecting rod assembly 3. The rotating link assembly 2 includes a first link 21, a second link 22 and a rotating drive member 23, wherein the rotating drive member 23 is installed on the bracket 1, the first link 21 is hinged to the bracket 1, the rotating drive member 23 is transmission-connected to the first link 21, the first link 21 is hinged to the second link 22, and the second link 22 is used to press the hinge of the box; the angle control link assembly 3 is installed on the bracket 1, the angle control link assembly 3 is hinged to the second link 22 to control the rotation angle of the second link 22; the rotating drive member 23 rotates the first link 21 to drive the end of the second link 22 close to the first link 21 to move away from the bottom of the box and the end of the second link 22 away from the first link 21 to move towards the hinge of the box, so that the length direction of the second link 22 is at a first angle 4 with the plane where the side wall of the box is located, and the second link 22 presses the hinge of the box.

[0040] The rotating link assembly 2 and the angle control link assembly 3 in the embodiment of the present application are each provided with two groups, the bracket 1 includes a connecting panel and a mounting branch, and both side walls of the connecting panel are respectively provided with a group of rotating link assemblies 2 and a group of angle control link assemblies 3, the side walls of the connecting panel are hinged to the first link 21 and the angle control link assembly 3, the mounting branch is connected to the connecting panel, the mounting branch is arranged on the side of the connecting panel away from the second link 22, and the rotating drive member 23 is installed on the mounting branch.

[0041] The rotating drive member 23 can be a linear motor, an electric cylinder or a pneumatic cylinder. The present application prefers a pneumatic cylinder. A connecting block for hinged connection with the first connecting rod 21 is provided on the driving shaft of the cylinder. If the stroke of the cylinder is large, the cylinder can be tilted to shorten the stroke of the cylinder in the vertical direction.

[0042] The first connecting rod 21 and the second connecting rod 22 may be straight rods.

[0043] The angle control link assembly 3 can be a tension spring, one end of which is mounted on the bracket 1 , and the other end of which is mounted on the second link 22 .

[0044] The rotating driving member 23 is connected to one end of the first connecting rod 21, and the rotating driving member 23 presses one end of the first connecting rod 21 downward along a linear motion, and rotates the first connecting rod 21. The end of the first connecting rod 21 away from the rotating driving member 23 drives the end of the second connecting rod 22 close to the first connecting rod 21 to move in a direction away from the bottom of the box body, and the end of the second connecting rod 22 away from the first connecting rod 21 moves in a direction close to the hinge of the box body, that is, the end of the second connecting rod 22 away from the first connecting rod 21 rotates in a direction away from the bracket 1, so that the length direction of the second connecting rod 22 forms a first angle 4 with the plane where the side wall of the box body is located, and the second connecting rod 22 contacts the box hinge to press the box hinge to prevent the box hinge from debonding. At the same time, the angle control connecting rod assembly 3 is hinged to the second connecting rod 22 to prevent the first angle 4 from being too large, causing the end of the second connecting rod 22 away from the first connecting rod 21 to move toward the inside of the box body, thereby damaging the box body.

[0045] Compared with the traditional way of achieving capping, which requires at least a lifting device and a rotating device to achieve the two actions of rotation and pressing down, the present application can achieve the two actions of rotation and pressing down with only one rotating drive member 23, and the cost of the present application is relatively low.

[0046] The first angle 4 is 80°-110°. If the first angle 4 is less than 80°, the side wall of the second connecting rod 22 will not contact the box hinge, and the box hinge cannot be pressed. If the first angle 4 is greater than 110°, the end of the second connecting rod 22 away from the first connecting rod 21 will move toward the inside of the box, causing damage to the box hinge.

[0047] Preferably, the first angle 4 is 85°. At this angle, a cover plate 6 with a certain thickness can be installed on the second connecting rod 22 to press the hinge of the box body without damaging the hinge of the box body, and the actual effect is the best.

[0048] Optionally, the rotating drive member 23 drives the first connecting rod 21 to rotate in the opposite direction, so as to drive the end of the second connecting rod 22 close to the first connecting rod 21 to move toward the bottom of the box body and the end of the second connecting rod 22 away from the first connecting rod 21 to move toward the bracket 1, so that the length direction of the second connecting rod 22 forms a second angle 5 with the plane where the side wall of the box body is located, so as to reduce the space occupied by the cover pressing device.

[0049] The rotating driving member 23 moves one end of the first connecting rod 21 upward along a linear motion, and rotates the first connecting rod 21. The end of the first connecting rod 21 away from the rotating driving member 23 drives the end of the second connecting rod 22 close to the first connecting rod 21 to move toward the bottom of the box body, thereby causing the end of the second connecting rod 22 away from the first connecting rod 21 to move away from the hinge of the box body, that is, the end of the second connecting rod 22 away from the first connecting rod 21 rotates toward the direction close to the bracket 1, so that the first angle 4 between the length direction of the second connecting rod 22 and the plane where the side wall of the box body is located is reduced to a second angle 5, so that the projection of the cover pressing device in the vertical direction becomes smaller, the space occupied by the cover pressing device is reduced, and the cover pressing device can also be used in narrow spaces, thereby improving the adaptability of the cover pressing device.

[0050] The second angle 5 is less than 80°. If the second angle 5 is not less than 80°, the side wall of the second connecting rod 22 will contact and interfere with the hinge of the box body, and the occupied space of the cover pressing device cannot be reduced.

[0051] Preferably, the second angle 5 is 15°. At this angle, the second connecting rod 22 will not interfere with the hinge of the box body, and the space occupied by the cover pressing device is minimal.

[0052] Preferably, the angle control link assembly 3 includes a third link 31, a fourth link 32 and a fifth link 33, the third link 31 is hinged to the second link 22, the third link 31 is hinged to the fourth link 32, the fourth link 32 is hinged to the bracket 1, the fourth link 32 is hinged to the fifth link 33, the fifth link 33 is hinged to the first link 21, and the rotating drive member 23 rotates the first link 21 to drive the third link 31, the fourth link 32 and the fifth link 33 to rotate.

[0053] The third connecting rod 31 and the fifth connecting rod 33 are both straight rods. The fourth connecting rod 32 can be a straight rod. The fifth connecting rod 33 is arranged between the fourth connecting rod 32 and the first connecting rod 21.

[0054] The rotating driving member 23 is connected to one end of the first connecting rod 21, and the rotating driving member 23 presses one end of the first connecting rod 21 downward along a linear motion, and rotates the first connecting rod 21. The end of the first connecting rod 21 away from the rotating driving member 23 drives the end of the second connecting rod 22 close to the first connecting rod 21 to move away from the bottom of the box body, and the end of the second connecting rod 22 away from the first connecting rod 21 moves toward the direction close to the box hinge, that is, the end of the second connecting rod 22 away from the first connecting rod 21 rotates away from the bracket 1, so that the length direction of the second connecting rod 22 forms a first angle 4 with the plane where the side wall of the box is located, and the second connecting rod 22 contacts the box hinge to press the box hinge.

[0055] At the same time, the end of the fifth link 33 close to the fourth link 32 moves toward the first link 21, the end of the fourth link 32 away from the bracket 1 rotates toward the first link 21, the end of the third link 31 away from the second link 22 rotates toward the first link 21, and the end of the third link 31 close to the second link 22 rotates away from the bracket 1, so that the distance between the end of the third link 31 close to the second link 22 and the bracket 1 increases, and the second link 22 is pulled while the second link 22 presses the hinge of the box to prevent the second link 22 from continuing to rotate, causing the end of the second link 22 away from the first link 21 to move toward the inside of the box and damage the box.

[0056] On the contrary, the first angle 4 becomes smaller to the second angle 5, the distance between the end of the third connecting rod 31 close to the second connecting rod 22 and the bracket 1 is reduced, the projection of the cover pressing device in the vertical direction becomes smaller, and the space occupied by the cover pressing device is reduced, so that the cover pressing device can also be used in narrow spaces, thereby improving the adaptability of the cover pressing device.

[0057] Preferably, the fourth connecting rod 32 includes a first straight rod portion and a first connecting portion, the first straight rod portion is hinged to the third connecting rod 31, the first straight rod portion is hinged to the bracket 1, the first connecting portion is arranged on the side wall of the first straight rod portion, and the first connecting portion is hinged to the fifth connecting rod 33.

[0058] The rotating driving member 23 is connected to one end of the first connecting rod 21, and the rotating driving member 23 presses one end of the first connecting rod 21 downward along a linear motion, and rotates the first connecting rod 21. The end of the first connecting rod 21 away from the rotating driving member 23 drives the end of the second connecting rod 22 close to the first connecting rod 21 to move away from the bottom of the box body, and the end of the second connecting rod 22 away from the first connecting rod 21 moves toward the direction close to the box hinge, that is, the end of the second connecting rod 22 away from the first connecting rod 21 rotates away from the bracket 1, so that the length direction of the second connecting rod 22 forms a first angle 4 with the plane where the side wall of the box is located, and the second connecting rod 22 contacts the box hinge to press the box hinge.

[0059] At the same time, one end of the fifth link 33 close to the first connecting portion of the fourth link 32 moves toward the first connecting rod 21, the first connecting portion of the fourth link 32 rotates toward the bracket 1, and the end of the first straight rod portion of the fourth link 32 away from the bracket 1 rotates toward the first connecting rod 21, and the end of the third link 31 away from the second link 22 rotates toward the first connecting rod 21, and the end of the third link 31 close to the second connecting rod 22 rotates away from the bracket 1, so that the distance between the end of the third link 31 close to the second connecting rod 22 and the bracket 1 is increased, and the second connecting rod 22 is pulled while the second connecting rod 22 presses the hinge of the box body to prevent the second connecting rod 22 from continuing to rotate, causing the end of the second connecting rod 22 away from the first connecting rod 21 to move toward the inside of the box body, thereby damaging the box body.

[0060] On the contrary, the first angle 4 becomes smaller to the second angle 5, the distance between the end of the third connecting rod 31 close to the second connecting rod 22 and the bracket 1 is reduced, the projection of the cover pressing device in the vertical direction becomes smaller, and the space occupied by the cover pressing device is reduced, so that the cover pressing device can also be used in narrow spaces, thereby improving the adaptability of the cover pressing device.

[0061] The first connecting portion can enable the first straight rod portion of the fourth connecting rod 32 to maintain a certain distance from the fifth connecting rod 33 during rotation, thereby preventing interference between the first straight rod portion and the fifth connecting rod 33 .

[0062] Preferably, the first connecting rod 21 includes a second straight rod portion 211, a second connecting portion 212 and a bending portion 213, the second connecting portion 212 is arranged on the side wall of the second straight rod portion 211, the second connecting portion 212 is hinged to the fifth connecting rod 33, the second straight rod portion 211 is hinged to the bracket 1, the second straight rod portion 211 is hinged to the rotating driving member 23, the end of the second straight rod portion 211 away from the bracket 1 is connected to the bending portion 213, the bending portion 213 is bent toward the cover plate 6, and the bending portion 213 is hinged to the second connecting rod 22.

[0063] The rotating driving member 23 is connected to one end of the second straight rod portion 211 of the first connecting rod 21, and the rotating driving member 23 presses one end of the second straight rod portion 211 downward along a linear motion, and rotates the first connecting rod 21. The bent portion 213 of the first connecting rod 21 away from the end of the rotating driving member 23 drives the second connecting rod 22 to move in a direction away from the bottom of the box body, and the second connecting rod 22 moves in a direction close to the hinge of the box body away from the bent portion 213 of the first connecting rod 21, that is, the second connecting rod 22 is rotated in a direction away from the bracket 1 at the end away from the first connecting rod 21, so that the length direction of the second connecting rod 22 forms a first angle 4 with the plane where the side wall of the box body is located, and the second connecting rod 22 contacts the hinge of the box body to press the hinge of the box body.

[0064] The second connecting portion 212 can increase the distance between the second straight rod portion 211 of the first connecting rod 21 and the fifth connecting rod 33 to prevent the first connecting rod 21 from interfering with the fifth connecting rod 33 when rotating. The bending portion 213 can increase the distance between the second straight rod portion 211 of the first connecting rod 21 and the fifth connecting rod 33 to prevent the first connecting rod 21 from interfering with the fifth connecting rod 33 when rotating, and the bending portion 213 can shorten the driving stroke of the rotating driving member 23 to improve the working efficiency of the rotating driving member 23.

[0065] The angle between the length direction of the bending portion 213 and the length direction of the second straight rod portion 211 is an obtuse angle. If the bending portion 213 is an acute angle or a right angle, the second connecting rod 22 hinged to the bending portion 213 will be too close to the bracket 1, which may cause the contact length between the second connecting rod 22 and the box hinge to be reduced, so that the second connecting rod 22 cannot fully press the box hinge, resulting in partial debonding of the box hinge, so the bending portion 213 needs to be an obtuse angle.

[0066] Preferably, the angle between the length direction of the bent portion 213 and the length direction of the second straight rod portion 211 is 135°. At this angle, the second connecting rod 22 can fully press the box hinge, causing the box hinge to partially debond.

[0067] The cover pressing device further comprises a cover plate 6, which is mounted on the side wall of the second connecting rod 22. The cover plate 6 is used to press the box hinge, and the cover plate 6 is mounted on the side wall of the second connecting rod 22 through a position-adjustable structure. The cover plate 6 can increase the pressure-bearing surface of the box hinge to prevent excessive pressure from causing indentations on the box hinge. The position-adjustable structure can adjust the position of the cover plate 6 to make the pressing position of the cover plate 6 more accurate.

[0068] The position adjustable structure may include an adjusting waist-shaped hole and a fixing screw. The second connecting rod 22 is provided with a mounting screw hole screwed with the fixing screw. The adjusting waist-shaped hole is provided on the cover plate 6. The fixing screw passes through the adjusting waist-shaped hole on the cover plate 6 and is screwed with the mounting screw hole on the second connecting rod 22. The head of the fixing screw abuts against the edge of the adjusting waist-shaped hole so that the cover plate 6 is installed on the side wall of the second connecting rod 22.
