Description

Technical Field

[0001] This utility model relates to the field of packaging equipment, and in particular to a semi-automatic box folding machine. Background Technology

[0002] Packaging boxes, as one of the most common packaging methods in daily life, are widely used in many industries due to their significant advantages in facilitating transportation, storage, and promoting sales. From food and electronic products to daily necessities, almost all kinds of goods rely on packaging boxes.

[0003] However, the current production and packaging process for products has significant shortcomings in the box forming and product loading processes. Specifically, packaging boxes are typically flat sheets of paper in their initial state, requiring manual folding into a three-dimensional structure in subsequent packaging steps before the product is placed inside to complete the packaging process. This traditional packaging method is not only inefficient and labor-intensive, but also prone to inconsistent box forming quality due to variations in operator skill levels and fatigue during manual folding, thus affecting the overall packaging effect and consumer experience. Utility Model Content

[0004] The main purpose of this invention is to propose a semi-automatic box folding machine, which aims to solve the problem of low work efficiency when manually folding packaging boxes.

[0005] To achieve the above objectives, this utility model proposes a semi-automatic box folding machine, including a frame and further comprising:

[0038] This utility model proposes a semi-automatic box folding machine, including a frame 100, and further comprising:

[0039] The feeding mechanism 110 includes a feeding bin 111 and a movable suction box assembly 114. The feeding bin 111 is used to store packaging box cardboard.

[0040] The box feeding mechanism 120 is located on one side of the material dispensing bin 111 and includes a fixed block 121 and a movable block 122. The box suction assembly 114 transports the cardboard of the packaging box to the fixed block 121. The movable block 122 moves toward the fixed block 121 to fold the cardboard of the packaging box into a three-dimensional packaging box. The box feeding mechanism 120 is installed on the first stroke module 123 and can reciprocate along the setting direction of the first stroke module 123.

[0041] The box folding mechanism 130 is located on the movement path of the box feeding mechanism 120 and is used to fold and insert the tongue of the packaging box conveyed by the box feeding mechanism 120.

[0042] The feeding mechanism 140 is located at the end of the box folding mechanism 130 away from the box feeding mechanism 120, and is used to feed out the packaging box with the flaps folded and the flaps inserted.

[0043] Please see Figures 1 to 9The semi-automatic box folding machine proposed in this application includes a supporting frame 100, and a feeding mechanism 110, a box feeding mechanism 120, a box folding mechanism 130, and a unloading mechanism 140 disposed on the frame 100. The feeding mechanism 110 is used to store unfolded packaging box cardboard and transport the packaging box cardboard to the box feeding mechanism 120 through the box suction assembly 114. During the process of sending the packaging box to the box folding mechanism 130, the box feeding mechanism 120 folds the unfolded packaging box cardboard into a three-dimensional packaging box. The box folding mechanism 130 performs folding and tongue insertion operations on the bottom tongue edge of the three-dimensional packaging box. The unloading mechanism 140 then sends out the packaging box with one end folded.

[0044] Specifically, the feeding mechanism 110 consists of a feeding bin 111 and a box suction assembly 114. Unfolded packaging cardboard is placed in the feeding bin 111. The box suction assembly 114 is located on the side of the feeding bin 111 and is movably mounted on the frame 100. The box suction assembly 114 sucks out the packaging cardboard in the feeding bin 111 and transports it to the box feeding mechanism 120.

[0045] The box feeding mechanism 120 is located on one side of the material feeding bin 111. The box feeding mechanism 120 also includes a fixed block 121 and a movable block 122. After the box suction assembly 114 transports the cardboard packaging to the position of the fixed block 121, the movable block 122, moving towards the fixed block 121, unfolds the cardboard packaging along the fold line to form a three-dimensional packaging box. This design automatically folds the packaging box from a flat, paper-like form into a three-dimensional box without manual folding, reducing labor intensity and improving work efficiency.

[0046] Since the entire box feeding mechanism 120 is mounted on the first stroke module 123, it can move along the direction set by the first stroke module 123. A box folding mechanism 130 is installed along the movement path of the box feeding mechanism 120, capable of folding and inserting the tongue of the packaging box. Specifically, the box folding mechanism 130 folds the small tongues on both sides of the end of the packaging box that contacts the mechanism 130 towards the inside of the packaging box, and folds the large tongue on the end of the packaging box that contacts the mechanism 130 towards the inside of the packaging box, so that the large tongue presses down on the small tongues on both sides and inserts the large tongue into the inside of the packaging box, thereby completing the box folding operation at one end of the packaging box.

[0047] The unloading mechanism 140 is located at the end of the box folding mechanism 130 away from the box feeding mechanism 120. After the packaging box completes the box folding operation on the box folding mechanism 130, the unloading mechanism 140 sends the packaging box out.

[0048] In summary, through the cooperation of the box feeding mechanism 120 and the box folding mechanism 130, the flat packaging cardboard in the feeding mechanism 110 can be folded into a three-dimensional packaging box. The tongue at one end is folded and inserted to form the three-dimensional shape of the packaging box. Finally, the unloading mechanism 140 delivers a packaging box with one end already folded. The operator only needs to place the product into the unfolded end of the packaging box and then fold the other end. This eliminates the need for manual folding of the cardboard into a three-dimensional packaging box, reducing manual steps, increasing automation, and thus improving work efficiency.

[0049] In some embodiments, the box feeding mechanism 120 further includes a mounting plate, a first stroke module 123 is disposed on the mounting plate, a sliding seat is disposed on the first stroke module 123, the sliding seat can move along the first stroke module 123, a mounting frame 124 is disposed on the sliding seat, a fixed block 121 is disposed at one end of the mounting frame 124 away from the box folding mechanism 130, a connecting block is movably disposed on the mounting frame 124, and a movable block 122 is movably mounted on the connecting block through a rotating shaft, and the movable block 122 moves closer to or away from the fixed block 121 as the rotating shaft moves.

[0050] like Figure 3 As shown, in this embodiment, the fixed block 121 has an L-shaped notch on the side facing the feeding mechanism 110. When the suction box assembly 114 transports the cardboard of the packaging box to the position that contacts the fixed block 121, the movable block 122 moves toward the fixed block 121. After the flat cardboard of the packaging box is subjected to the force of the movable block 122, it is transformed into a three-dimensional packaging box under the guidance of the L-shaped notch of the fixed block 121.

[0051] In some embodiments, the folding box mechanism 130 includes a folding tongue plate 131, which is disposed on the movement path of the box feeding mechanism 120. One end of the folding tongue plate 131 is inclined. A scraper tongue plate 132 is also disposed on one side of the folding tongue plate 131. The scraper tongue plate 132 is movably mounted on the frame 100 via a swing shaft 133. The scraper tongue plate 132 moves with the swing shaft 133 and contacts or separates from the inclined end of the folding tongue plate 131, for folding the small tongues on both sides of the bottom of the packaging box that have passed through the folding tongue plate 131.

[0052] like Figure 4As shown, in this embodiment, the folding mechanism 130 includes a folding tongue plate 131 and a scraping tongue plate 132. One end of the folding tongue plate 131 facing the scraping tongue plate 132 is inclined downwards, while the other end is horizontal. The scraping tongue plate 132 is mounted on the frame 100 via a swing shaft 133, and moves with the swing shaft 133, contacting or separating from the inclined end of the folding tongue plate 131. It should be noted that the end of the scraping tongue plate 132 facing the folding tongue plate 131 is also inclined. When the box feeding mechanism 120 moves the packaging box to the position of the folding tongue plate 131, the folding tongue plate 131 and the scraping tongue plate 132 work together to fold the small tongues on both sides of the bottom of the packaging box inwards. Specifically, as... Figure 1 As shown in the diagram, since the feeding mechanism 110 is located to the right of the folding mechanism 130, the box feeding mechanism 120 transports the packaging box from right to left onto the folding tongue plate 131. During the movement of the packaging box from right to left, the small tongue on the left side of the bottom of the packaging box contacts the inclined end of the folding tongue plate 131, causing the small tongue on the left side to fold to the right. At this time, the scraper 132 is separated from the folding tongue plate 131 to avoid interfering with the movement of the packaging box. After the packaging box is in place, the scraper 132 moves toward the folding tongue plate 131 under the action of the swing shaft 133 until it contacts the folding tongue plate 131. The inclined end of the scraper 132 drives the small tongue on the right side of the bottom of the packaging box to fold to the left, thus completing the process of folding the small tongues on both sides of the bottom of the packaging box toward the inside of the packaging box.

[0053] In some embodiments, the folding mechanism 130 further includes a tongue assembly, which is located on the side of the folding tongue plate 131 away from the scraping tongue plate 132, and the tongue assembly includes a lifting cylinder 135 disposed on the frame 100, and a tongue plate 134 is disposed on the piston rod of the lifting cylinder 135.

[0054] The tongue assembly also includes a second stroke module 136 disposed on the frame 100. A folding tongue pusher 137 is movably mounted on the second stroke module 136. The setting direction of the second stroke module 136 is perpendicular to the setting direction of the first stroke module 123. The folding tongue pusher 137 can move along the setting direction of the second stroke module 136 to approach or move away from the position of the tongue plate 134.

[0055] like Figure 5As shown, in this embodiment, the tongue assembly includes a lifting cylinder 135 and a tongue plate 134. The lifting cylinder 135 is mounted on the frame 100, and the tongue plate 134 is mounted on the piston rod of the lifting cylinder 135, enabling the tongue plate 134 to move up and down to complete the tongue insertion action. A second stroke module 136 is also provided on the frame 100. The setting direction of the second stroke module 136 is perpendicular to the setting direction of the first stroke module 123. When the second stroke module 136 drives the folding tongue pusher 137 to move toward the position of the tongue plate 134, it folds the large tongue at the bottom of the packaging box toward the inside of the packaging box. Specifically, since the tongue inserter 134 is located on the side of the folding tongue plate 131 away from the scraping tongue plate 132, when the box feeding mechanism 120 delivers the packaging box to the position of the tongue inserter 134, the small tongues on both sides of the bottom of the packaging box have already been folded. At this time, the second stroke module 136 causes the folding tongue pusher 137 to move from back to front, pushing the large tongue at the bottom of the packaging box to fold inwards. Then, the lifting cylinder 135 drives the tongue inserter 134 to move upwards, inserting the large tongue at the bottom of the packaging box into the packaging box. Since the cross-section of the tongue inserter 134 is L-shaped and there is a fold line on the large tongue at the bottom of the packaging box, when the folding tongue pusher 137 pushes the large tongue at the bottom of the packaging box, the large tongue will fold upwards along the fold line under the guidance of the L-shaped tongue inserter 134. In this way, when the tongue inserter 134 rises, it can smoothly insert the large tongue into the packaging box, thereby completing the folding and insertion of all the tongues at the bottom of the packaging box.

[0056] In some embodiments, the tongue assembly further includes a third stroke module 138 disposed on the frame 100. The third stroke module 138 is disposed on the side of the tongue plate 134 away from the folding tongue plate 131. The setting direction of the third stroke module 138 is parallel to the setting direction of the first stroke module 123. A pressing tongue plate 139 is movably mounted on the third stroke module 138. The pressing tongue plate 139 can move along the setting direction of the third stroke module 138 to approach or move away from the position of the tongue plate 134.

[0057] like Figure 5As shown, in this embodiment, a third stroke module 138 is also provided on the side of the tongue plate 134 away from the folding tongue plate 131. The setting direction of the third stroke module 138 is parallel to the setting direction of the first stroke module 123. The initial position of the tongue depressor 139 on the third stroke module 138 is above the tongue plate 134. When the box feeding mechanism 120 transports the packaging box with the bottom two small tongues already folded to the position of the tongue plate 134, the upper surface of the tongue depressor 139 contacts the bottom two small tongues of the packaging box to prevent the folded small tongues from popping out. After the folding tongue pusher 137 folds the large tongue, the third stroke module 138 drives the tongue depressor 139 to move away from the tongue plate 134 to prevent interference with the movement of the tongue plate 134. If the folded small tongues at the bottom of the packaging box pop out, they will block the movement path of the folding tongue pusher 137. If the folding tongue pusher 137 continues to move, it will cause damage to the packaging box. By setting the tongue depressor 139, this phenomenon is effectively avoided, and the overall stability is improved.

[0058] In some embodiments, a push plate 125 is provided at one end of the mounting bracket 124 away from the fixing block 121. One end of the push plate 125 is movably mounted on the mounting bracket 124 via a rotating shaft, and the other end of the push plate 125 moves closer to or away from the mounting bracket 124 along with the rotating shaft.

[0059] In some embodiments, the unloading mechanism 140 includes a box ejection track 141, which is connected to the box folding mechanism 130. An upper tongue positioning component is provided above the box ejection track 141. The upper tongue positioning component includes a front guide plate 142 and a rear guide plate 143. The gap between the front guide plate 142 and the rear guide plate 143 is used to accommodate the upper tongue of the packaging box. The ends of the front guide plate 142 and the rear guide plate 143 located above the box folding mechanism 130 are positioned far apart from each other.

[0060] The upper tongue positioning assembly also includes a fourth stroke module 144 vertically mounted on the frame 100. The front guide plate 142 and the rear guide plate 143 are both movably mounted on the fourth stroke module 144 and can move up and down along the fourth stroke module 144.

[0061] like Figure 3 and Figure 6As shown, in this embodiment, the push plate 125 is located at the end of the mounting frame 124 away from the fixing block 121, and the push plate 125 is movably mounted on the mounting frame 124 via a rotating shaft. The box ejection track 141 is connected to the end of the folding tongue plate 131 away from the scraping tongue plate 132. When the push plate 125 moves with the rotating shaft, it can push the packaging box located on the folding mechanism 130 onto the box ejection track 141. A front guide plate 142 and a rear guide plate 143 are also provided above the box ejection track 141. There is a gap between the front guide plate 142 and the rear guide plate 143. This gap is the channel through which the upper tongue of the packaging box passes when the packaging box runs on the box ejection track 141. Specifically, at the end above the folding mechanism 130, the front guide plate 142 and the rear guide plate 143 are positioned far apart from each other. This is to facilitate the smooth entry of the upper tongue of the packaging box into the gap between the front guide plate 142 and the rear guide plate 143 when the box feeding assembly delivers the packaging box to the folding mechanism 130, thereby limiting the positioning of the packaging box. The arrangement of the front guide plate 142 and the rear guide plate 143 ensures that the packaging box is less likely to shift during the folding and inserting operations of the folding mechanism 130, and also prevents the folded packaging box from tipping over when moving on the exit track 141; thus improving overall stability and reliability.

[0062] A fourth-stroke module 144 is vertically mounted on the frame 100. The fourth-stroke module 144 has a lifting plate, on which the front guide plate 142 and the rear guide plate 143 are mounted. When the fourth-stroke module 144 moves the lifting plate, the front guide plate 142 and the rear guide plate 143 move up and down together. This arrangement allows the front guide plate 142 and the rear guide plate 143 to flexibly adjust their height according to the size of the packaging box, thus accommodating boxes of different heights. In other embodiments, the fourth-stroke module 144 can also be vertically mounted on an electric slide rail, which moves the fourth-stroke module 144 back and forth. In this way, the front guide plate 142 and the rear guide plate 143 can also be adjusted in position according to boxes of different widths, further improving compatibility.

[0063] In some embodiments, the side of the box ejection track 141 away from the box folding mechanism 130 is connected to the ejection slide plate 145. A feeding stop bar 146 is provided on the side of the box ejection track 141 near the ejection slide plate 145. A pusher bar 147 is provided at the end of the ejection slide plate 145 near the box ejection track 141. The pusher bar 147, in conjunction with the feeding stop bar 146, pushes the packaging box on the box ejection track 141 into the ejection slide plate 145.

[0064] like Figure 7As shown, in this embodiment, the discharge slide plate 145 is located on the side of the box-discharging track 141 away from the folding mechanism 130, and a discharge stop bar 146 is provided at the position of the discharge slide plate 145 on the box-discharging track 141. The discharge slide plate 145 is designed with an inclination, with one end closer to the box-discharging track 141 being higher than the other end. A push rod 147 capable of telescopic movement is provided on the higher end of the discharge slide plate 145. Here, the push rod 147 can be an electric push rod or a piston rod of a cylinder. The discharge stop bar 146 is located above the push rod 147. When the push rod 147 extends, it works in conjunction with the discharge stop bar 146 to push the packaging box that was originally standing on the box-discharging track 141 over, causing the packaging box to slide downwards along the inclined surface of the discharge slide plate 145 under the action of gravity, thereby completing the discharge. Pushing the packaging box over increases the contact area between the packaging box and the discharge slide plate 145, preventing the packaging box from accidentally detaching from the discharge slide plate 145 during the downward movement, thus ensuring the smooth progress of the unloading process.

[0065] In some embodiments, the discharge bin 111 is composed of two side panels 112, one of which is movably mounted on the fifth stroke module 113. The fifth stroke module 113 drives the side panel 112 to move to adjust the width of the discharge bin 111.

[0066] The suction box assembly 114 includes multiple suction components and a sixth stroke module 115. The setting direction of the sixth stroke module 115 is perpendicular to the setting direction of the first stroke module 123. The suction components are all movably mounted on the sixth stroke module 115. The sixth stroke module 115 drives the suction components to move to pick up the packaging boxes in the dispensing bin 111 and transport them to the box feeding mechanism 120.

[0067] like Figure 8 As shown, in this embodiment, a fifth stroke module 113 is also installed on the frame 100. The setting direction of the fifth stroke module 113 is parallel to the setting direction of the first stroke module 123. The outline of the feeding bin 111 is composed of two side panels 112, one of which is set on the fifth stroke module 113. The fifth stroke module 113 moves this side panel 112 closer to or further away from the other fixed side panel 112, thereby adjusting the width of the feeding bin 111. This allows the width of the feeding bin 111 to be adjusted according to the size of the packaging box, improving its applicability. It is understood that in other embodiments, the feeding bin 111 may also be composed of multiple side panels 112, all of which are movable, allowing for a larger adjustment range of the feeding bin 111.

[0068] like Figure 9As shown, in this embodiment, the suction box assembly 114 includes two suction components arranged side by side and a sixth stroke module 115. The sixth stroke module 115 is located on one side of the feeding bin 111 and is arranged perpendicular to the first stroke module 123. Each suction component includes a connecting tube and a suction cup. One end of the connecting tube is mounted on the sixth stroke module 115, and the other end is connected to the suction cup. The suction cup is used to adsorb the cardboard packaging box. When the sixth stroke module 115 drives the connecting tube to move, the suction cup moves along with the cardboard packaging box, thereby transporting the cardboard packaging box from the feeding bin 111 to the box feeding mechanism 120. It should be noted that the number of suction components can be set according to actual needs, and the suction box assembly 114 also includes an air pump connected to the suction cup.

[0069] In some embodiments, the rack 100 is further provided with an electrical control box 150, which is used to house the power supply and the controller. The rack 100 is also provided with a touch screen 160 that is electrically connected to the controller.

[0070] like Figure 2 As shown, in this embodiment, an electrical control box 150 is provided at the bottom of the frame 100. The electrical control box 150 has internal cavities for housing the power supply, controller, and various electronic components. A touch screen 160 is also provided at the top of the frame 100. The touch screen 160 is electrically connected to the controller inside the electrical control box 150. The touch screen 160 displays various parameters and statuses of the semi-automatic box folding machine proposed in this application, and these parameters and statuses can be adjusted through the touch screen 160. It is understood that the touch screen 160 can also be directly connected to the control circuit, as long as the operator can control the semi-automatic box folding machine proposed in this application through the touch screen 160.

[0071] In summary, this utility model proposes a semi-automatic box folding machine, including a feeding mechanism 110, a box feeding mechanism 120, a box folding mechanism 130, and a unloading mechanism 140 arranged on a frame 100. The feeding mechanism 110 feeds flat packaging box cardboard to the box feeding mechanism 120. During the process of sending the packaging box to the box folding mechanism 130, the box feeding mechanism 120 folds the packaging box cardboard into a three-dimensional packaging box. The box folding mechanism 130 then folds and inserts the tongue at the bottom edge to complete the three-dimensional forming of the packaging box. Finally, the unloading mechanism 140 delivers the packaging box with one end folded, allowing the product to be directly placed into the packaging box from the unfolded end, reducing manual operation steps, improving automation, and thus increasing work efficiency.
