Description

Technical Field

[0001] The utility model relates to the technical field of packaging product production equipment, in particular to a paper handle production device. Background Art

[0002] In daily life, common food packaging boxes are usually equipped with handles for easy lifting, carrying and transporting. For example, the top of a milk box is often equipped with a handle that can be detached after independent assembly. The handle is also called a handle, a carrying handle, a lifting ring, a handle buckle, etc. Its common structure includes a main body that is easy for people to hold and plug-in ends at both ends of the main body. The top of the box structure is provided with plug-in holes corresponding to the two plug-in ends. The two (referring to the plug-in ends and the plug-in holes) are plugged in and self-locked with each other to make the end of the handle bear force, thereby achieving the effect of bearing weight when lifting and holding the main body. The plug-in end of the handle has two structures: longitudinal extension and transverse extension according to its width extension direction. For example Figure 3 The application of a common handle structure is shown, in which a plug-in end 2 is provided at both ends of a (curved) long strip main body 1, and the plug-in end 2 is a transversely extending structure. In the illustrated structure, the handle structure has been plugged into the plug-in hole at the top of the box body 3 through its plug-in end 2, and the main body 1 is arched upward for people to pull with their hands. In some applications, when the material of the top of the box is thin and the force-bearing capacity is weak, it is easy to cause the top structure of the box where the plug-in end is located to be damaged when pulling. In response to such a situation, a cushioning member can be provided to cushion the inner wall of the top of the box, and another group of plug-in holes corresponding to the plug-in holes at the top of the box are provided at both ends of the cushioning member. The plug-in end of the handle passes through the plug-in hole at the top of the box and the plug-in hole of the cushioning member in turn, and then exerts force. When pulling, its force is mainly borne by the cushioning member, thereby reducing the load on the top of the box and reducing its damage.

[0003] The handle structures in the prior art are mostly plastic products and paper products. Among them, plastic products are often manufactured using the injection molding process, which requires prefabricating molds of corresponding specifications, selecting suitable plastic masterbatch raw materials, and using injection molding machines to complete the manufacturing. The equipment energy consumption and mold design and manufacturing have high manufacturing thresholds and corresponding costs, which makes it impossible to reduce its production costs. In addition, the manufacturing materials have a certain risk of pollution to the environment; paper products are generally made of recycled materials, which are pressed at high temperatures to form cardboard. The cardboard is cut, folded, and pasted to form the main body, and then the paper pieces corresponding to the shape of the connector are glued to the two ends of the fork to form the final product. Its structure is as follows Figure 4 , Figure 5 As shown, it includes a main body 1 (main material) formed by folding and pasting long strips of cardboard and a plug-in end formed by pasting an independent paper piece 4 (patch) to the forked end of the main body 1. Figure 5The structural details of the plug-in end are shown. The end of the main body 1 is a superimposed structure (formed after folding). After unfolding the end of the superimposed structure (after cutting off part of the end structure), it is folded into a vertical flat surface, and the independent paper piece 4 is glued to the flat surface by glue 5. Paper handles are more economical and environmentally friendly than plastic products because they are easy to obtain and have low requirements for manufacturing equipment. However, there are shortcomings in the manufacturing process. Due to its relatively weak structural strength, during production, the molded cardboard (main material) of the main body is often folded to form the main body into a two-layer or even multi-layer structure, and then folded at the end into the shape of a plug-in, and an independent paper piece (patch) corresponding to the shape of the plug-in is glued on it for reinforcement. The entire production process includes multiple folding, cutting, gluing, bifurcated flattening, patching and other processes for different molded paper pieces. Due to the flexibility of paper products and the problem that they are easy to spread after gluing, they are not suitable for mechanical production, so manual means are often used for production and manufacturing. However, manual production is not only inefficient, but also prone to production defects. For example, the judgment of the symmetrical position when folding, the control of the amount of glue when dripping glue, the cutting quality, etc. will affect the final molding effect and production speed. Therefore, its production quality varies, and the output cannot be effectively improved. Utility Model Content

[0043] Reference Figure 1 , Figure 2 , a paper handle production device, comprising: a feeding component 100, a feeding component 200, a bending component 300, a gluing component, a cutting component 500, an unfolding component 600, and a patch component 700, wherein:

[0044] The material supply component 100 is used to supply materials to the subsequent production links. The materials include the main material. The middle section structure of the main material is formed into the main body of the handle, and the two end structures cooperate with the patch supplied later to form the plug-in end of the handle;

[0045] The material conveying assembly 200 is located below the material feeding assembly 100 and is used to convey materials to various processing positions. The material conveying assembly 200 includes a conveyor. The conveyor is provided with a material slot on its conveying surface for placing materials. The conveyor is provided with processing stations at intervals along its conveying direction. The processing stations include a bending station, a gluing station, a cutting station, an unfolding station, and a patch station.

[0046] The bending assembly 300 is arranged at the bending station, and includes a bending working part for bending the main material. The bending assembly is used to fold the two end structures of the main material so as to facilitate forming the handle structure with the plug-in component.

[0047] The gluing component is arranged at the gluing station, including a gluing work part (e.g., a gluing gun) for gluing the main material. The gluing component is used to gluing the bonding position of the material when the material passes through the corresponding processing station, so as to facilitate the finalization of the structure after bending;

[0048] The cutting assembly 500 is arranged at the cutting station, and includes a cutting working part (e.g., a high-speed rotating disc-shaped cutting blade) for partially cutting the ends of the main material that has been bent and folded together. The cutting assembly 500 is used to cut the two ends of the main material that has been bent and shaped, so that it is bifurcated and formed into a bifurcated structure that is convenient for pasting the patch and forming it into a plug-in component.

[0049] The unfolding assembly 600 is arranged at the unfolding station, and includes an unfolding working part for flattening the end of the bifurcated main material after cutting. The unfolding assembly 600 is used to unfold the bifurcated structure of the bent bonding structure at both ends of the cut main material to form a bonding surface perpendicular to the length direction of the main material, so as to facilitate the patch bonding;

[0050] The patch assembly 700 is arranged at the patch station, including a patch supply mechanism and a patch working part. The patch assembly 700 is used to attach the patch to the bonding surface, so that the two ends of the main material are formed into plug-in ends. Among them, the patch supply mechanism has a material trough, which pushes the patches stored therein forward to the location of the patch working part, and the patch working part pushes the patches to the main material flat surface for bonding.

[0051] It should be noted that a sensor unit is provided at each processing station to detect the presence of materials.

[0052] In the utility model, the material includes a main material of a paper strip structure and a patch of a square sheet structure. The main part of the main material is formed into a structure for people to carry and pull after it is finally formed into a handle structure. The two ends of the main material cooperate with the patches, and after being bonded to each other, they are formed into plug-in ends that are plugged into the plug hole / slot of the box. In addition, when the feeding component of the utility model provides materials to the feeding component, it adopts an accumulation-type feeding, that is, the materials are placed in a pile on the feeding component, and are discharged to the starting end of the feeding component in a single piece. After the materials are discharged, they are placed on the conveying surface of the conveyor and fall into the material card slot. The length direction is perpendicular to the conveying direction, so that the two ends of the main material are respectively placed on both sides of the conveying direction, so that the processing mechanisms of each processing station located in the conveying direction can perform bending, gluing, cutting, and unfolding operations.

[0053] The utility model sets the feeding assembly according to the following structure: in some embodiments, as Figure 1 , Figure 2 As shown, the feeding assembly 100 is arranged just above the starting end of the feeding assembly 200.

[0054] The feeding assembly 100 includes an inclined material chute and a material baffle plate. The material baffle plate is arranged at the lower end of the material chute so that during the falling process of the main material, it can be corrected and fall smoothly into the material slot of the conveyor of the feeding assembly below.

[0055] The utility model sets the bending assembly according to the following structure, so that it has better bending and pressing effects: in some embodiments, the bending assembly includes a first bending mechanism 301 and a second bending mechanism 302 arranged at intervals along the conveying direction of the feeding assembly, and correspondingly, the bending station includes a first bending position and a second bending position,

[0056] The first bending mechanism 301 is arranged at the first bending position, and is used to pre-bend the material, so that it has a bending tendency, so that after the glue dispensing operation of the glue assembly, the bending structure can be firmly bonded during the subsequent bending.

[0057] The second bending mechanism 302 is disposed at the second bending position, and is used to compact the material with a bending tendency (after being pre-bent at the first bending position), so that the folded structure after bending is firmly bonded together by glue.

[0058] Specifically, Fig.10 , Fig.11 As shown, the first bending mechanism is used to pre-bend the flat end of the main material. The first bending mechanism has a vertical insert tooth 3011, which is driven by a cylinder 3012 to perform lifting and lowering movements. In its initial state, the top of the vertical insert tooth 3011 is located below the conveying surface of the conveyor, so that the end of the main material 9 being conveyed can pass above the vertical insert tooth 3011. When reaching the first bending position, the vertical insert tooth 3011 is lifted up and then cooperates with the baffle plate 3013 to pre-bend the end of the main material 9 so that the end and the main body (middle section) of the main material 9 are mutually perpendicular. The state of the main material 9 after pre-bending facilitates the insertion of the horizontal insert tooth during the subsequent second folding. The baffle plate 3013 can be fixed to the conveyor of the feeding assembly through a bracket.

[0059] like Fig.12 As shown, the second bending mechanism is used to flatten the vertical structure of the pre-bent end of the main material so that it overlaps with the main body surface of the main material that has not been folded. In the structure shown in the figure, the second bending mechanism has a horizontal insert 3021, which has two insert ends that are spaced apart and parallel to each other, and the space between the two insert ends is used as a means to press the turned-up structure of the end of the main material 9. The horizontal insert 3021 is driven by the cylinder 3022 to extend and retract horizontally. Figure 8 The figure shows the structural state of the end of the main material after being bent by the second bending mechanism.

[0060] In some usage scenarios of the present invention, there may be a small interval between the bending processes (for example, when a double material feeding structure is set, the material conveying frequency is relatively dense, so that the time interval between the first bending and the second bending processes is relatively short). In order to avoid the bending process interval being too close and the bending operation of the second bending position being unable to achieve a good compaction effect, the following settings can be made: In some preferred embodiments, such as Figure 1As shown, the bending assembly 300 includes a third bending mechanism 303. Correspondingly, the bending station includes a third bending position, which is arranged between the first bending position and the second bending position. The three bending positions are spaced apart from each other, and the third bending mechanism 303 is arranged at the third bending position.

[0061] It should be noted that the structure of the third bending mechanism is set with reference to the second bending mechanism, the only difference being that the third bending mechanism has a wider toothing surface and a larger toothing opening. The function is to press down the vertical part of the pre-bent end of the main material, but not to flatten it, but only to strengthen the downward turning tendency of the pre-bent vertical end, so that when the second bending mechanism's toothing flattens it later, the damage to the bend of the main material end can be reduced.

[0062] The utility model sets the glue assembly according to the following structure: In some embodiments, such as Figure 1 , Figure 2 As shown, the gluing assembly includes a first gluing mechanism 401 and a second gluing mechanism 402. Correspondingly, the gluing station includes a first gluing station and a second gluing station.

[0063] The first glue dispensing mechanism 401 is disposed at the first glue application position, which is located between the first bending mechanism 301 and the feeding assembly 100, and the bending operation of the auxiliary bending assembly 300 is to glue the two ends of the main material;

[0064] The second glue dispensing mechanism 402 is disposed at the second glue applying position, which is located between the unfolding component and the patch component, and assists the patch component in gluing the two ends of the main material (forked and flattened);

[0065] The first glue dispensing mechanism and the second glue dispensing mechanism are configured as cold glue dispensing mechanisms.

[0066] like Figure 1 As shown in FIG. 1 , after the main material is unloaded from the feeding component to the conveying surface of the conveying component, the first gluing operation is carried out. After the main material passes through the first gluing position, the conveyor stops, and the glue gun head of the first glue dispensing mechanism dispenses a predetermined amount of cold glue to the surface of the main material. Figure 6 , Figure 7 The surface condition of the main material after glue dispensing is shown, wherein the glue dispensing position 1001 is the cold glue position, that is, the action point of the first glue dispensing mechanism.

[0067] In order to prevent the cold glue of the first gluing mechanism from being unable to effectively play a good overlapping and fixing role on the pre-bending bending structure (first bending mechanism), the utility model can be arranged according to the following structure: in some preferred embodiments, the gluing component includes a third gluing mechanism 403, and correspondingly, the gluing station includes a third gluing position, the third gluing mechanism 403 is arranged at the third gluing position, and the third gluing position is located between the first gluing position and the first bending position 301; the third gluing mechanism 403 is arranged as a hot glue gluing mechanism.

[0068] like Figure 6 , Figure 7 The surface of the main material after glue dispensing is shown, wherein the glue dispensing position 1002 is the hot glue position, that is, the action point of the third glue dispensing mechanism.

[0069] It can be observed from the structure shown in the figure that a first glue dispensing mechanism action point and a third glue dispensing mechanism action point are respectively provided at symmetrical positions at both ends of the main material.

[0070] The cutting assembly 500 of the present invention comprises a disc-shaped cutting blade fixed to a bottom surface foundation by a bracket. Fig. 9 In the structure shown, the leftmost side shows the end of the main material after being cut by the cutting assembly. Fig. 9 In the structure shown, from left to right are cutting operation, flattening / unfolding operation, and patching operation.

[0071] It should be noted that a collection basket may be provided below the cutting assembly 500 to facilitate collection of the cut scraps 9001 after they fall into the basket, thereby avoiding scattering at the work site and causing safety hazards.

[0072] In order to avoid the bending and bonding structure of the material, the utility model is loosely bifurcated before cutting, and can be arranged according to the following structure: In some embodiments, such as Figure 1 , Figure 2 As shown, a pressing assembly 801 is provided between the bending assembly 300 and the cutting assembly 500, and the pressing assembly 801 includes a first bracket, a guide plate 8011 and a first pressure strip 8012, and the guide plate 8011 and the first pressure strip 8012 are fixed to the conveyor of the feeding assembly via the first bracket;

[0073] Along the conveying direction of the feeding assembly, the guide plate 8011 is located before the first pressure strip 8012 .

[0074] When the utility model is working, the bent main material is corrected by the guide plate and sent into the first pressure strip to be pressed and shaped, so that the main material has a better posture and is convenient for improving the cutting accuracy.

[0075] After the material of the utility model is cut at the cutting station, in order to avoid premature bifurcation of the overlapping structures at both ends of the main material and affect the subsequent unfolding operation, and to avoid the overlapping structure being loosened and causing the unfolded structure to be deformed or separated from each other, the following structure can be set: In some embodiments, such as Figure 1 , Figure 2As shown, a fixing component 802 is provided at the unfolding component 600, and the fixing component 802 includes a second bracket 8021 and a second pressure strip 8022. The second bracket 8021 fixes the second pressure strip 8022 on the conveyor of the feeding component, and the second pressure strip 8022 extends from behind the cutting component to the unfolding component along the conveying direction of the feeding component, that is, after cutting, the main material (of the material) enters the action range of the fixing component 802, and is conveyed to the unfolding component 600 to flatten the bifurcated structures at both ends (that is, the bifurcated structure is unfolded to be perpendicular to the length direction of the main material) During the unfolding operation, the fixing / pressing effect of the fixing component 802 is still maintained, thereby playing a certain positioning and supporting effect in the flattening operation, and the basis for maintaining the effect is that the second pressure strip 8022 limits the main material from arching upward on the horizontal plane. Because in the flattening operation, the unfolding working part of the unfolding component 802 extends from both sides of the conveyor to the opposite direction of the conveyor into the forked position of the end part of the main material, so it has a certain thrust along the length direction of the main material. At this time, if there is no limiting effect of the second pressure strip, the middle section of the main material may arch upward and weaken the flattening effect, so that it cannot be perpendicular to the length direction of the main material after flattening, affecting the subsequent patch operation effect. Fig.13 A schematic structural diagram of an unfolding working portion is shown, which has a tooth-inserting end 6001 extending into the fork at the end of the main material and a flattening end 6002 for pushing up the fork structure to flatten it relative to the length direction of the main material. The tooth-inserting end 6001 is a horizontal structure, and the flattening end 6002 is a triangular plate structure with an inclined surface.

[0076] In order to improve the strength of the patch, the utility model can be arranged according to the following structure: In some embodiments, such as Figure 1 , Figure 2 As shown, a pressing assembly 803 is provided behind the patch assembly 700, and the pressing assembly 803 is used to perform secondary pressing on the patch that has been attached to the end of the unfolded main material (the secondary pressing here is relative to the primary pressing during the patch operation), so that it is firmly attached to form a plug-in end;

[0077] The tablet pressing assembly 803 includes a third bracket and a third pressure strip 8031, and the third pressure strip 8031 ​​is fixed to the conveyor of the feeding assembly via the third bracket. In addition, in order to ensure smooth transportation, a guide plate 8032 can be provided before the third pressure strip 8031, which is located after the patch assembly 700, that is, after the patch operation is completed, the third pressure strip 8031 ​​is pressed again after entering the guide plate 8032 for deviation correction. It should be noted that the third pressure strip can be tilted so that the two third pressure strips arranged opposite to each other show a contraction trend and gradually close together along the conveying direction, so that the opposite ends of the already attached patch of the main material are gradually pressed inward. In order to avoid the main material from arching during the pressing process, the tablet pressing assembly 803 also includes a pressing plate 8033, which is arranged on the conveying surface within the action range of the third pressure strip.

[0078] In consideration of batch operation, the utility model can adopt a symmetrical layout structure to set up two sets of unloading structures to achieve double-station unloading to improve production capacity: In some embodiments, such as Figure 1 , Figure 2 As shown, two feeding assemblies are provided just above the starting end of the conveying surface of the feeding assembly, and the two feeding assemblies are symmetrically arranged along the feeding direction.

[0079] The utility model realizes a more efficient production rhythm, shortens the feeding time and improves the production capacity by setting a double feeding structure of the feeding component and coordinating and controlling the conveying time. Figure 1 As shown, along the conveying direction of the conveyor, two sets of front and rear feeding components are arranged just above the starting end thereof, including a first feeding part 101 and a second feeding part 102. The unloading structures of the two sets of feeding components are arranged face to face, that is, the unloading plates of the two sets of feeding components are arranged in opposite directions. In the structure shown in the figure, the unloading plate on the right side is inclined to the left side, and the unloading plate on the left side is inclined to the right side.

[0080] It should be noted that the main material of the utility model is before feeding, such as Figure 6 , Figure 7 As shown, there are three folds between the gluing position and the end. The middle fold is used for the bending operation at the first bending position, and the folds on both sides of the middle fold are used as folding reference points when the main material end is cut and flattened.

[0081] When the utility model is produced based on the production devices of the above examples, the following steps can be performed to produce paper handles:

[0082] 1. The feeding component uses vacuum and cylinder to put the main material into the material chute for accumulation, and is blocked by the baffle. After the material is picked up by the picking mechanism (generally constructed by a flip suction cup), it is placed in the material slot on the conveying surface of the conveying component directly below and sent to the next station (the first gluing station) for the first cold glue dispensing;

[0083] 2. During the main material conveying process, when it reaches the gluing station, the conveyor stops and the cold glue gun (first and second gluing mechanisms) and the hot glue gun (third gluing mechanism) inject corresponding glue at the set position on the main material surface (the role of hot glue is to play a preliminary fixing role first);

[0084] 3. After the first and third gluing positions are glued, they are sent to the first, third and second bending positions in turn to bend and overlap the ends of the main materials;

[0085] 4. Before cutting, press and fix the parts to ensure stable subsequent cutting.

[0086] 5. Cutting operation, cut off the excess parts at both ends of the main material;

[0087] 6. Under the action of the fixing assembly, the main material with the excess part of the end cut off enters the unfolding station to flatten the end fork;
