For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In the production and processing of packaging boxes, it is common to pre-place a mold that can play a supporting and reinforcing role in the cavity formed by the blank plates, and then wrap the three-dimensional structure formed by the blank plates with surface paper to make it a closed and three-dimensional box blank; after that, the box blank needs to be trimmed to obtain an opening, and the upper cover of the box blank is opened from the opening to remove the mold, thereby obtaining a packaging box with a usable storage space inside.

[0037] In the existing technology, the closed and three-dimensional box blank is often manually trimmed with a sharp tool to obtain an opening, and then the box blank is manually opened from the opening to remove the mold. Manual operation has high labor density, safety hazards, low operation efficiency, and poor quality consistency of the products obtained by the operation.

[0038] The box blank trimming and molding device of the present invention performs trimming and molding processing on the above-mentioned box blanks, realizes automatic trimming and molding of three-dimensional box blanks, improves operation safety, saves labor, ensures stable quality of products obtained by trimming and molding, and improves operation efficiency.

[0039] Embodiment 1:

[0040] The box blank trimming and molding device of the present invention comprises a conveying component including a first conveyor belt 1 and a second conveyor belt 2 which form a certain angle with each other and can sequentially transfer the box blanks, and the angle formed by the first conveyor belt 1 and the second conveyor belt 2 is greater than 0° and less than 180°; at the same time, the cutting component included in the box blank trimming and molding device comprises at least two cutters 3, and at least one side edge of the first conveyor belt 1 is provided with a cutter 3 capable of cutting the box blanks conveyed on the first conveyor belt 1, and at least one side edge of the second conveyor belt 2 is provided with a cutter 3 capable of cutting the box blanks conveyed on the second conveyor belt 2.

[0041] When the box blank is conveyed by the first conveyor belt 1, the cutter 3 arranged on the side of the first conveyor belt 1 performs trimming processing on the edge of the box blank facing the cutter 3; when the box blank is conveyed to the end by the first conveyor belt 1, it can be translated from the end of the first conveyor belt 1 to the second conveyor belt 2, and continue to be conveyed with the second conveyor belt 2. At this time, the cutter 3 arranged on the side of the second conveyor belt 2 performs trimming processing on the edge of the box blank facing the cutter 3. Because there is a certain angle between the first conveyor belt 1 and the second conveyor belt 3, the sides of the box blank facing the cutter 3 on the two conveyor belts are different. In the process of conveying the box blank with the two conveyor belts, the cutter 3 automatically cuts different edges of the box blank to form an opening that can be opened. Here, the angle formed by the adjacent faces of the box blank that need to be trimmed can be set to be the same as the angle between the first conveyor belt 1 and the second conveyor belt 2. In this way, the cutter 3 can trim the box blank more closely, and it is also more accurate and smooth. Because most box blanks are rectangular, such as Figure 1 , Figure 3 , Figure 4 In the box blank C shown in the figure, preferably, the first conveyor belt 1 and the second conveyor belt 2 can be set to form an angle of 90°, and the two are distributed in an L shape.

[0042] The box blanks that have undergone automated trimming by the cutting assembly continue to be conveyed along the second conveyor belt 2, and when passing through a cover opening assembly disposed on the side of the second conveyor belt 2, the cover opening actuator included in the cover opening assembly can open the box blank from the opening formed by the trimming of the box blank, and then the box blanks continue to be conveyed along the second conveyor belt 2, and when passing through a mold taking assembly disposed on the side of the second conveyor belt 2, the mold taking actuator included in the mold taking assembly can remove the mold from the opened box blank, thereby obtaining a packaging box with a usable accommodating space inside.

[0043] As a result, the labor of manually trimming and demolding the box blanks with sharp tools can be eliminated, safety hazards can be reduced, the quality of the products obtained by automated trimming and demolding is stable, and the operating efficiency is significantly improved.

[0044] Embodiment 2:

[0045] On the basis of the structure of the first embodiment, preferably, the cutting assembly can be provided to further include at least two tool adjustment seats, each tool adjustment seat correspondingly adjusting the position of a cutter 3 relative to the first conveyor belt 1 or the second conveyor belt 2, and each tool adjustment seat includes a vertical adjustment assembly and / or a horizontal adjustment assembly, wherein the vertical adjustment assembly can adjust the vertical distance of the cutter 3 relative to the first conveyor belt 1 or the second conveyor belt 2, and the horizontal adjustment assembly can adjust the horizontal distance of the cutter 3 relative to the first conveyor belt 1 or the second conveyor belt 2. Thus, the cutting assembly here can adjust the position of the cutter 3 to adapt to box blanks of different sizes, thereby improving the compatibility of the cutting assembly.

[0046] Here, if Figure 2 The figure is a schematic diagram of the structure of an embodiment of the cutter and tool adjustment seat in the present invention, wherein the vertical adjustment assembly includes a cutter mounting seat 4, a vertical adjustment screw 5 that cooperates with the vertically opened threaded hole on the cutter mounting seat 4, and a horizontal adjustment screw 6 that cooperates with the horizontally opened threaded hole on the cutter mounting seat 4, and the cutter 3 is fixedly installed (preferably detachably fixedly installed) on the cutter mounting seat 4.

[0047] When the vertical adjustment screw 5 is rotated, the cutter mounting seat 4 can drive the cutter 3 to rise or fall relative to the first conveyor belt 1 or the second conveyor belt 2 on its side; when the horizontal adjustment screw 6 is rotated, the cutter mounting seat 4 can drive the cutter 3 to approach or move away from the first conveyor belt 1 or the second conveyor belt 2 on its side; the above adjustment operation is continued until the cutter 3 is adjusted to a position where the box blank can be correctly trimmed (the above vertical adjustment screw 5 and horizontal adjustment screw 6 can be set as manual fine-tuning screws to make the position adjustment operation of the cutter 3 accurate and flexible).

[0048] Embodiment three:

[0049] Since a box blank often has a group of opposite edges that need to be cut, in order to improve the efficiency of edge cutting, on the basis of the structure of the first or second embodiment:

[0050] A cutter 3 is provided on each of the two opposite sides of the first conveyor belt 1, and a cutter 3 is provided on one side of the second conveyor belt 2;

[0051] Alternatively, a cutter 3 is provided on each of the two opposite sides of the second conveyor belt 2, and a cutter 3 is provided on one side of the first conveyor belt 1;

[0052] Alternatively, a cutter 3 is provided on each of the two opposite sides of the first conveyor belt 1 , and a cutter 3 is provided on each of the two opposite sides of the second conveyor belt 2 .

[0053] Preferably, the two cutters 3 arranged on the opposite side edges of the first conveyor belt 1 are symmetrically distributed relative to the first conveyor belt 1, and / or the two cutters 3 arranged on the opposite side edges of the second conveyor belt 2 are symmetrically distributed relative to the second conveyor belt 2; when the two cutters 3 arranged on the two side edges simultaneously trim the box blanks, their horizontal forces offset each other and the box blanks are stable.

[0054] Generally, most box blanks are rectangular, such as Figure 1 , Figure 3 , Figure 4 As shown, a rectangular box blank C is taken as an example. Generally, three of the four circumferential side surfaces of the box blank C can be trimmed to obtain a flip-lid packaging box that can be opened with one side connected and three sides open.

[0055] When it is planned to cut two opposite sides and then one side of the box blank C, a cutter 3 can be set on each of the opposite side edges of the first conveyor belt 1, and a cutter 3 can be set on one side of the second conveyor belt 2. The box blank C loaded onto the first conveyor belt 1 has a set of opposite sides that need to be cut parallel to the two opposite sides of the first conveyor belt 1, which facilitates the cutters 3 set on both side edges of the first conveyor belt 1 to cut a set of opposite sides of the box blank C. When the box blank C is translated from the first conveyor belt 1 to the second conveyor belt 2, the third side edge that needs to be cut faces the cutter 3 set next to the second conveyor belt 2, and can be cut by the cutter 3 set next to the second conveyor belt 2.

[0056] When it is planned to cut one side edge and then two opposite sides of the box blank C, a cutter 3 can be set on each of the opposite side edges of the second conveyor belt 2, and a cutter 3 can be set on one side edge of the first conveyor belt 1. The box blank C loaded onto the first conveyor belt 1 has a side edge that needs to be cut facing the cutter 3 set next to the first conveyor belt 1, and can be cut by the cutter 3 set next to the first conveyor belt 1. When the box blank is translated from the first conveyor belt 1 to the second conveyor belt 2, a group of opposite sides that need to be cut are parallel to the two opposite sides of the second conveyor belt 2, which facilitates the cutters 3 set on both side edges of the second conveyor belt 2 to cut a group of opposite sides of the box blank C.

[0057] If the box blank C is loaded in a fixed posture, it is not limited whether the pair of opposite sides to be cut is parallel to the two sides of the first conveyor belt 1 or the two sides of the second conveyor belt 2 during loading. Figure 1 , Figure 3 , Figure 4As shown, a cutter 3 can be set on each of the two opposite sides of the first conveyor belt 1, and a cutter 3 can be set on each of the two opposite sides of the second conveyor belt 2. When the box blank C is loaded in a fixed posture, if it needs to cut a group of opposite sides first, the cutters 3 on the two opposite sides of the first conveyor belt 1 are adjusted by the horizontal adjustment assembly in the tool adjustment assembly to cut a group of opposite sides of the box blank C. The cutters 3 on the two opposite sides of the second conveyor belt 2 are also adjusted by the horizontal adjustment assembly in the tool adjustment assembly to make one of the cutters 3 cut the third side that needs to be cut by the box blank C, and the other cutter 3 cannot cut the box blank C, so as to improve the flexibility of the cutting assembly without limiting the loading posture of the box blank C. Of course, the cutters 3 set on both sides of the first conveyor belt 1 and the second conveyor belt 2 can also be adjusted by adjusting the horizontal adjustment assembly of the tool adjustment seat to achieve cutting a group of opposite sides and then cutting a side edge of the box blank.

[0058] Embodiment 4:

[0059] On the basis of the structures of the above embodiments, the box blank trimming and mold-taking device of the present invention can also be designed to include a box blank limiting mechanism, which can limit the box blanks conveyed to the position of the cutter 3 and avoid the cutter 3 at the same time; the box blank limiting mechanism includes a vertical limiting component and / or a horizontal limiting component, wherein the vertical limiting component can limit the box blanks in the vertical direction from above the first conveyor belt 1 or the second conveyor belt 2, and the horizontal limiting component can limit the box blanks in the horizontal direction from the opposite sides of the first conveyor belt 1 or the second conveyor belt 2. The above box blank limiting mechanism can keep the box blanks stable during the trimming process of the cutter 3, and ensure the quality of the product obtained by the trimming operation of the cutter 3.

[0060] Embodiment five:

[0061] Based on the structure of the fourth embodiment, preferably, Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the vertical limiting component in the box blank limiting mechanism can be designed to include a plurality of horizontal rotating members 7 (specifically, the horizontal rotating member 7 here can be a roller or a rotating shaft) which are arranged in parallel in the same horizontal plane and perpendicular to the conveying direction of the first conveyor belt 1 or the second conveyor belt 2 directly below it; when the box blank passes under the horizontal rotating member 7, the horizontal rotating member 7 has a vertical limiting effect on it, and at the same time will not cause excessive obstruction to the conveyance of the box blank along the first conveyor belt 1 or the second conveyor belt 2. The horizontal limiting assembly in the box blank limiting mechanism includes a plurality of vertical rotating members 8 (similarly, the vertical rotating members 8 here can be selected from rollers or rotating shafts) which are arranged in parallel on the opposite side edges of the first conveyor belt 1 or the second conveyor belt 2 and are arranged in a line along the side edges of the first conveyor belt 1 or the second conveyor belt 2; when the box blank passes between the vertical rotating members 8 located on the opposite side edges of the first conveyor belt 1 or the second conveyor belt 2, the vertical rotating members 8 have a horizontal limiting effect on it, and at the same time will not cause excessive obstruction to the transmission of the box blank along the first conveyor belt 1 or the second conveyor belt 2.

[0062] Embodiment six:

[0063] As a further improvement based on the structure of the fifth embodiment, the blank limiting mechanism can be designed to also include a vertical adjustment mechanism and / or a horizontal adjustment mechanism, wherein the vertical adjustment mechanism can adjust the relative position of the vertical limiting assembly and the first conveyor belt 1 or the second conveyor belt 2 in the vertical direction, and the horizontal adjustment mechanism can adjust the relative position of the horizontal limiting assembly and the first conveyor belt 1 or the second conveyor belt 2 in the horizontal direction to accommodate blanks of different sizes.

[0064] Specifically, Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, preferably, the vertical adjustment mechanism can be preferably designed to include a first slider rail structure (preferably an electric double slider rail structure to improve stability) and a first mounting seat 9, the first slider rail structure includes a first slider 10 and a first rail 11, and the horizontal rotating member 7 is installed on the first mounting seat 9 connected to the first slider 10 through a bearing. Therefore, when the first slider 10 slides along the first rail 11, it can drive the first mounting seat 9 to move vertically, and then drive the horizontal rotating member 7 to do lifting and lowering movements to adapt to box blanks of different heights.

[0065] At the same time, the horizontal adjustment mechanism can be preferably designed to include a second slider rail structure (preferably an electric double slider rail structure to improve stability), a second mounting seat 12 and a third mounting seat 13, the second slider rail structure includes a second slider 14 and a second rail 15, and vertical rotating members 8 located on opposite sides of the first conveyor belt 1 or the second conveyor belt 2, wherein the vertical rotating member 8 on one side is mounted on the second mounting seat 12 through a bearing, and the vertical rotating member 8 on the other side is mounted on the third mounting seat 13 through a bearing, and the second mounting seat 12 is connected to the second slider 14, so that when the second slider 14 slides along the second rail 15, it can drive the second mounting seat 12 to move horizontally, and then drive the vertical rotating member 8 to do translational movement, so as to adjust the distance between the vertical rotating members 8 located on opposite sides of the first conveyor belt 1 or the second conveyor belt 2, so as to adapt to box blanks of different widths. (Here, the third mounting seat 13 can be designed to be fixed or adjustable similar to the second mounting seat 12.)

[0066] The above vertical adjustment mechanism and / or horizontal adjustment mechanism can improve the compatibility of the box blank limiting mechanism.

[0067] Embodiment seven:

[0068] On the basis of Example 6, preferably, the vertical adjustment mechanism can be designed to include a first spring 16, which is connected to the vertical limit assembly and can drive the vertical limit assembly to float in the vertical direction; the horizontal adjustment mechanism includes a second spring 17, which is connected to the horizontal limit assembly and can drive the horizontal limit assembly to float in the horizontal direction.

[0069] Specifically, Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a first fixed beam 18 can be preferably designed, and the first fixed beam 18 is fixedly connected to the first slide rail 11, and the first spring 16 (a spring guide column coaxial with the first spring 16 can be provided in the first spring 16 to maintain the stability of the first spring 16) is located between the first mounting seat 9 and the first fixed beam 18. When the first slider 10 drives the first mounting seat 9 to rise, the first spring 16 is compressed; when the box blank is transferred to the bottom of the horizontal rotating member 7, the first slider 10 is released, and the first mounting seat 9 rebounds under the restoring force of the first spring 16, and the horizontal rotating member 7 presses above the box blank to limit it.

[0070] Similarly, a second fixed beam 19 can be preferably designed, and the second fixed beam 19 is fixedly connected to the second slide rail 15. The second spring 17 (a spring guide column coaxial with the second spring 17 can be provided in the second spring 17 to maintain the stability of the second spring 17) is located between the second mounting seat 12 and the second fixed beam 19. When the second slider 15 drives the second mounting seat 12 away from the first conveyor belt 1 or the second conveyor belt 2 on its side, the second spring 17 is compressed; when the box blank is conveyed to between the vertical rotating members 8 located on the opposite side edges of the first conveyor belt 1 or the second conveyor belt 2, the second slider 14 is released, and the second mounting seat 12 rebounds under the restoring force of the second spring 17, so that the vertical rotating member 8 is pressed on the two side edges of the box blank in the width direction to limit it.

[0071] The arrangement of the first spring 16 and the second spring 17 can improve the flexibility of the blank limiting mechanism, so that the blank limiting mechanism can not only play a good limiting role on the blank, but also prevent the blank from being stuck under the action of the blank limiting mechanism.

[0072] Embodiment eight:

[0073] Based on the structures of the above embodiments, the cover opening actuator in the cover opening assembly can be designed to include a first lifting mechanism 20 and a first suction cup mechanism 21 connected to each other, such as Figure 1 , Figure 7 As shown, when the box blank that has been trimmed by the cutting assembly is conveyed to the lid opening assembly along the second conveyor belt 2, the first lifting mechanism 20 (the first lifting mechanism 20 here is a slider rail structure, and of course other common linear motion mechanisms arranged along the vertical direction can also be selected) drives the first suction cup mechanism 21 to descend to a position capable of adsorbing the upper cover of the box blank, and the first suction cup mechanism 21 then draws a vacuum and sucks the upper cover of the box blank so that it can be opened, and the first lifting mechanism 20 drives the first suction cup mechanism 21 to move upward to complete the opening process of the upper cover of the box blank.

[0074] Of course, a translation mechanism capable of driving the first suction cup mechanism 21 to move horizontally can also be provided here (the translation mechanism here is not shown in the figure, and can preferably be a slider rail structure. Of course, other common single linear motion mechanisms or double linear motion mechanisms arranged in the horizontal direction can also be selected, which can form a two-way linkage displacement mechanism or even a three-axis linkage displacement mechanism with the first lifting mechanism 20). When processing box blanks of different sizes, the translation mechanism here can adjust the first suction cup mechanism 21 to be directly above the upper cover of the box blank, thereby ensuring the stability of the first suction cup mechanism 21 when opening the covers of box blanks of different sizes.

[0075] Here, the box blank can be designed to make a brief stop when it is conveyed to the lid opening component to wait for the lid opening actuator to open the lid. The brief stop of the box blank can be achieved by computer timing control of the conveying step of the second conveyor belt 2, and a sensor can be set to sense and detect the position of the box blank. When the sensor detects that the box blank is conveyed to the lid opening component, a feedback signal is sent to the power mechanism driving the second conveyor belt 2 to pause the driving. When the sensor detects that the box blank leaves the lid opening component, a feedback signal is sent to the power mechanism driving the second conveyor belt 2 to continue driving.

[0076] The structure of the above cover-opening actuator is simple and economical, and can ensure accurate and reliable cover-opening of the box blank. Of course, a structure similar to a manipulator can also be selected here to grab and open the upper cover of the box blank.

[0077] Embodiment nine:

[0078] On the basis of the structures of the above embodiments, the cover opening assembly can be designed to also include a guide member 22 arranged on the side of the second conveyor belt 2. When the opening angle of the upper cover of the box blank by the cover opening actuator is limited, the guide member 22 can guide the upper cover of the box blank that has been opened to a certain angle while the box blank continues to be conveyed with the second conveyor belt 2, so that it can be further opened to the opening degree of the box blank without interfering with the subsequent mold removal processing of the mold inside the box blank by the mold removal assembly.

[0079] Specifically, Figure 1 , Figure 8 As shown in the embodiment, it is assumed that the box blank here is a common rectangular flip-top packaging box, and the guide member 22 is set to be an arc-shaped plate bent toward the opening side of the box blank. The first suction cup mechanism 21 can open the upper cover of the box blank from its opening to a certain angle and then release it. At this time, the box blank continues to be conveyed along the second conveyor belt 2, so that the guide member 22 in the shape of an arc plate enters the opening of the box blank that has been opened to a certain extent, and further guides and opens (lifts) the upper cover of the box blank as the box blank is conveyed along the second conveyor belt 2.

[0080] The setting of the guide member 22 here can increase the opening degree of the upper cover of the box blank, and further ensure that after the upper cover of the box blank is acted upon by the cover opening assembly, the opened upper cover of the box blank will not interfere with the subsequent mold removal processing of the mold inside the box blank by the mold removal assembly.

[0081] Embodiment ten:

[0082] On the basis of the structures of the above embodiments, the mold removal component can be configured to include a second lifting mechanism 23 and a second suction cup mechanism 24 connected to each other. Figure 1 , Figure 8As shown, when the box blank that has been opened by the cover opening assembly is conveyed to the mold removal assembly along the second conveyor belt 2, the second lifting mechanism 23 (the second lifting mechanism 23 here is a slider rail structure, and of course other common linear motion mechanisms arranged along the vertical direction can also be selected) drives the second suction cup mechanism 24 to descend to a position capable of adsorbing the upper cover of the box blank, and the second suction cup mechanism 24 then draws a vacuum and tightly absorbs the mold in the box blank with the upper cover opened, and the second lifting mechanism 23 drives the second suction cup mechanism 24 to move upward to complete the operation of removing the mold from the box blank.

[0083] Here, the box blank can be designed to make a brief stop when it is transmitted to the mold removal component to wait for the mold removal actuator to perform the mold removal operation on it. Here, the brief stop of the box blank can be achieved by timing the transmission step of the second conveyor belt 2 through computer timing control, and a sensor can also be set to sense and detect the position of the box blank. When the sensor detects that the box blank is transmitted to the mold removal component, the sensor feeds back a signal to the power mechanism driving the second conveyor belt 2 to pause the driving. When the sensor detects that the box blank leaves the mold removal component, the sensor feeds back a signal to the power mechanism driving the second conveyor belt 2 to continue driving.

[0084] The structure of the above mold removal actuator is simple and economical, and can ensure that the mold removal process of the box blank is accurate and reliable. Of course, a structure similar to a manipulator can also be selected here to grab and remove the mold in the box blank.

[0085] Embodiment eleven:

[0086] Based on the structure of Example 10, the above mold removal actuator can be designed to also include a first translation mechanism 25 connected to the second suction cup mechanism 24, and the first translation mechanism 25 can drive the second suction cup mechanism 24 to translate horizontally between the top of the mold in the opened box blank and the position of the mold unloading.

[0087] In such Figure 1 , Figure 8 In the illustrated embodiment, a first translation mechanism 25 (the first translation mechanism 25 here is a slider rail structure, and of course other common linear motion mechanisms arranged in the horizontal direction may also be selected) forms a bidirectional linkage mechanism with the second lifting mechanism 23, and a mold unloading channel 26 is arranged at the position of the mold unloading. When the second lifting mechanism 23 drives the second suction cup mechanism 24 to move upward to complete the operation of removing the mold from the box blank, the first translation mechanism 25 drives the second suction cup mechanism 24 to move to the feed port of the mold unloading channel 26, and the second suction cup mechanism 24 releases the removed mold so that it falls into the mold unloading channel 26 for orderly unloading, so as to facilitate the recycling of the mold during the production and processing of the packaging box.

[0088] Of course, the first translation mechanism 25 can also be designed here to form a three-axis linkage mechanism with the second lifting mechanism 23. When processing box blanks of different sizes, the first translation mechanism 25 here can adjust the second suction cup mechanism 24 to be directly above the mold in the box blank, thereby ensuring the stability of the second suction cup mechanism 24 when taking out the molds in box blanks of different sizes.

[0089] Embodiment 12:

[0090] On the basis of the structures of the above embodiments, it can be designed that the cover opening assembly also includes a first limiting structure, and / or the mold removal assembly also includes a second limiting structure, wherein the first limiting structure is used to limit the other parts of the box blank except the upper cover when the cover opening actuator opens the upper cover of the box blank, so as to avoid the entire box blank moving with the force of the cover opening actuator when the cover opening actuator drives the upper cover of the box blank to open, resulting in the upper cover of the box blank being difficult to separate from other parts of the box blank. Similarly, the second limiting structure is used to limit the box blank when the mold removal actuator takes the mold in the box blank, so as to avoid the box blank and the mold moving with the mold when the mold removal actuator drives the mold displacement in the box blank, resulting in difficulty in removing the mold from the box blank.

[0091] Specifically, Figure 7 As shown, the first limiting structure includes a second translation mechanism 27 (the second translation mechanism 27 here is a slider rail structure, of course, other common linear motion mechanisms arranged in the horizontal direction can also be selected) and a limiting plate 28 that are connected to each other. When the first suction cup mechanism 21 descends and sucks the upper cover of the box blank and moves upward, the second translation mechanism drives the limiting plate 28 to move in the direction close to the box blank until it is pressed against the side wall of the box blank or the upper edge of the lower half of the box blank is pressed from the opening of the box blank (the lower half of the box blank here refers to the other part of the box blank except the upper cover. When the upper cover is opened to a certain gap relative to the lower half of the box blank, the upper edge of the lower half of the box blank can be exposed), thereby limiting the lower half of the box blank in the vertical direction so that the upper cover of the box blank can be opened smoothly.

[0092] Specifically, Fig. 9 As shown, the second limiting mechanism includes a plurality of rollers 29 which are horizontally arranged and arranged in sequence on the second conveyor belt 2 near the opening of the box blank. The rollers 29 can press against the side wall of the box blank or the upper edge of the lower half of the box blank (the lower half of the box blank here refers to the other part of the box blank except the upper cover. When the upper cover is opened relative to the lower half of the box blank, the upper edge of the lower half of the box blank can be exposed) to limit the position in the vertical direction so that the mold E can be separated from the box blank smoothly and thus be taken out by the mold removal assembly.

[0093] Embodiment 13:

[0094] On the basis of the structures of the above embodiments, preferably, the box blank trimming and mold-taking equipment of the present invention can also be designed to include a loading component, which includes a storage bin 30, a sloped loading channel 31 and a loading conveyor belt 32 that are interconnected; wherein the storage bin 30 can allow the box blanks to be arranged upright in sequence along the thickness direction thereof, one end of the sloped loading channel 31 is connected to the discharge port of the storage bin, and the other end extends to the first conveyor belt 1, forming a straight slope or an arc slope, and the loading conveyor belt 30 is laid on the lower bottom surface of the storage bin 30 and the sloped loading channel 31.

[0095] When the box blanks in the storage bin 30 are arranged upright in sequence along the thickness direction, compared with the box blanks being arranged flat, mutual interference during stacking, extrusion and loading of the box blanks in the gravity direction is avoided, which is conducive to storing more box blanks.

[0096] The feeding conveyor belt 32 drives the box blanks in the storage bin 30 to enter the slope feeding channel 31 through the discharge port and continue to be conveyed forward. Because the slope feeding channel is in a straight slope shape or an arc slope shape, such as Figure 1 , Fig.10 As shown, the sloped feeding channel 31 is in an arc-shaped slope. The box blanks entering the sloped feeding channel 31 fall forward along the sloped feeding channel 31 under the action of their respective gravity, and are loaded onto the first conveyor belt 1 in a stable and easy-to-process flat posture.

[0097] Embodiment 14:

[0098] On the basis of the structure of the thirteenth embodiment, the sloped feeding channel 31 can be further designed to include two opposite sloped side wall plates 310 arranged on opposite sides of the feeding conveyor belt 32 and a sloped limiting cover plate 311 arranged above the two opposite sloped side wall plates 310; when the sloped feeding channel 31 is in a straight slope shape, the sloped side wall plates 310 and the sloped limiting cover plate 311 are flat plates, or when the sloped feeding channel 31 is in an arc-shaped slope shape, such as Figure 1 , Fig.10 As shown, the slope side wall plate 310 and the slope limiting cover plate 311 are arc-shaped straight plates.

[0099] At this time, the sloped side wall plate 310, the sloped limiting cover plate 311 and the loading conveyor belt 32 together form the channel cavity of the sloped loading channel 31. When the box blanks are conveyed and poured in the sloped loading channel, the sloped side wall plate 310 and the sloped limiting cover plate 311 can limit them well, ensuring that the box blanks are stably conveyed in a specific posture.

[0100] Preferably, the distance between the opposite side wall panels of the storage bin 30 can be designed to be adjustable, and / or the distance between the two opposite sloped side wall panels 310 of the sloped feeding channel 31 can be adjustable, and / or the distance between the sloped limiting cover plate 311 of the sloped feeding channel 31 and the feeding conveyor belt 32 can be adjustable, so that the entire feeding assembly can adapt to box blanks of different sizes to improve the compatibility of the feeding assembly.

[0101] Embodiment 15:

[0102] On the basis of the structures of the above embodiments, a plurality of first limit blocks 33 located on the first conveyor belt 1 and arranged at intervals along the conveying direction of the first conveyor belt 1 can also be provided, and / or a plurality of second limit blocks 34 located on the second conveyor belt 2 and arranged at intervals along the conveying direction of the second conveyor belt 2 can be provided, and the first limit blocks 33 and the second limit blocks 34 can both push the box blanks located on their respective conveyor belts to move with the conveyor belts, so as to prevent the box blanks from sliding too far backward on the conveyor belts and not moving forward, or from interfering with each other due to sliding. Preferably, the first limit blocks 33 are designed to be evenly spaced on the first conveyor belt 1, and the second limit blocks 34 are evenly spaced on the second conveyor belt 2.

[0103] Embodiment 16:

[0104] On the basis of the structures of the above embodiments, preferably, the first conveyor belt 1 and / or the second conveyor belt 2 can be designed to include a chain conveyor belt; ordinary conveyor belts are generally made of rubber, and inevitably generate electrostatic friction or adsorption force with the blank plate of the box blank (generally cardboard), affecting the normal displacement of the box blank with the conveyor belt; chain conveyor belts are generally made of metal, and will not affect the normal displacement of the box blank due to other forces generated by the blank plate of the box blank.

[0105] And / or, the conveying assembly also includes a first power mechanism (not shown) for driving the first conveyor belt 1 and a second power mechanism (not shown) for driving the second conveyor belt 2, and the driving relationship is simple; of course, only one power mechanism can be set up, and the transmission structure can be designed so that one power mechanism can provide power for the first conveyor belt 1 and the second conveyor belt 2 at the same time, but the additional transmission structure will complicate the conveying and trimming equipment of the present invention.
