Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for assembling packaging box components, and in particular to a double-layer carton assembly guide device. Background Technology

[0002] Packaging boxes are used in various fields to wrap and store products in bulk for safe storage and transportation. This is especially true in the manufacturing industry, such as tobacco processing, where various sizes of tobacco boxes are needed as storage and transfer containers during the tobacco production and processing process to meet the storage and transportation needs of tobacco products.

[0003] Currently, to ensure the storage and transportation of tobacco products, double-layer cardboard box assemblies, consisting of inner and outer cardboard boxes, are commonly used as packaging containers for tobacco leaves in the tobacco processing industry. At present, the most common double-layer cardboard box assembly methods in the industry are generally divided into manual assembly and mechanical assembly.

[0004] Specifically, the manual assembly method involves workers manually fitting the outer cardboard box onto the inner cardboard box. The entire process relies entirely on manual operation, especially the alignment between the outer and inner cardboard boxes, which depends entirely on the worker's judgment. This requires a high level of skill and experience from the workers, and the consistency of the work becomes unstable after long-term continuous repetition. The manual assembly process is prone to damaging the cardboard boxes, making it impossible to guarantee the assembly quality of batch-processed double-layer cardboard box components.

[0005] Mechanical assembly relies on a lift and positioning machine that work in conjunction with the outer cardboard box to fit the outer cardboard box onto the inner cardboard box, thus completing the assembly of the double-layer cardboard box. However, this equipment structure, consisting of a lift and positioning mechanism, is extremely complex, has a high failure rate, and is difficult to maintain after long-term operation. The overall operating and maintenance costs are high, and the cardboard box can be damaged during the fitting process due to poor precision of the equipment components or misalignment of the boxes, resulting in an unsatisfactory final quality of the double-layer cardboard box assembly.

[0006] In view of this, how to optimize the assembly method of double-layer carton components, improve the alignment accuracy between the outer and inner cartons, make the assembly process of double-layer carton components simpler and smoother, and effectively improve the assembly efficiency and quality of double-layer carton components are important technical problems that need to be solved by those skilled in the art. Utility Model Content

[0007] The purpose of this invention is to provide a double-layer carton assembly guide device, which can effectively improve the alignment accuracy between the outer and inner cartons, making the assembly process of the double-layer carton assembly simpler and smoother, and effectively improving the assembly efficiency and quality of the double-layer carton assembly.

[0008] To solve the above-mentioned technical problems, this utility model provides a double-layer carton assembly guide device, including a guide seat that can be inserted into the inner carton from top to bottom. The height direction of the guide seat is consistent with the vertical direction. A plurality of face positioning components are provided on the outer side wall of the guide seat. The face positioning components include a positioning plate that extends obliquely along the height direction of the guide seat. The bottom edge of the positioning plate is pressed against the outer side wall of the guide seat, and the outer wall of the positioning plate can be attached to and abut against the inner side wall of the inner carton.

[0009] A ridge guide assembly is provided at the junction of two adjacent outer walls on the side of the guide seat. The ridge guide assembly includes a guide arm that is inclined along the height direction of the guide seat. The top end of the guide arm is hinged to the guide seat. The inner side wall of the guide arm and the guide seat are fitted with a clearance to form a guide gap for the side ridge of the inner carton to be inserted from bottom to top. The outer side wall of the guide arm can fit and slide with the inner cavity side ridge of the outer carton.

[0010] Preferably, a plurality of facial guide components are further provided on the outer side wall of the guide seat, and the facial guide components are arranged in a one-to-one correspondence with the facial positioning components;

[0011] The face guide assembly includes two guide support plates protruding from the outer side wall of the guide seat. The two guide support plates are aligned horizontally and fitted with a clearance. The face guide assembly also includes a guide roller that is horizontally arranged and can rotate on a fixed axis. The two ends of the guide roller are rotatably connected to the top of the two guide support plates through ball bearings.

[0012] In the face guide assembly and face positioning assembly arranged in alignment, the horizontal axis of the guide roller is higher than the top edge of the positioning plate, the outer edge of the guide roller protrudes from the side outer wall of the inner carton, and the guide roller can fit and roll to adapt to the side inner wall of the outer carton.

[0013] Preferably, the guide support plate is vertically disposed on the outer side wall of the guide seat, and the width of the guide support plate increases from bottom to top. The outer side edge of the guide support plate is tightly attached to and welded to the inner wall of the positioning plate.

[0014] Preferably, the positioning plate has several process holes running through it.

[0015] Preferably, the ridge guide assembly includes two guide supports protruding from the outer wall of the guide seat side portion. The two guide supports are aligned horizontally and fitted with a clearance. The ridge guide assembly also includes a horizontally arranged guide hinge shaft. The two ends of the guide hinge shaft are respectively fixedly inserted into the outer ends of the two guide supports. The top end of the guide arm has a hinge hole extending horizontally. The guide hinge shaft is inserted into the hinge hole and rotates to adapt, so that the guide arm is hinged to the guide hinge shaft.

[0016] Preferably, the ridge guide assembly further includes a buffer reset member disposed on the inner side of the guide arm to push the guide arm outward, the buffer reset member being capable of reciprocating extension and retraction along the hinge opening and closing direction of the guide arm.

[0017] Preferably, the buffer reset element is a torsion spring.

[0018] Preferably, the guide arm has a bent portion protruding in the middle towards the direction away from the guide seat, an assembly section is formed between the bent portion and the top end of the guide arm, and a guide section is formed between the bent portion and the bottom end of the guide arm, wherein the angle between the extension axis of the assembly section and the extension axis of the guide section is an obtuse angle.

[0019] Preferably, the inner sidewall of the guide arm is recessed with an inner positioning groove that fits snugly against the side edge of the inner carton.

[0020] Preferably, the outer side wall of the guide arm is provided with an outer positioning protrusion that fits into the inner cavity side edge of the outer carton.

[0021] Compared to the aforementioned background technology, the double-layer carton assembly guide device provided by this utility model, during operation, involves placing the guide seat into the top opening of the inner carton to be assembled from top to bottom, and gradually moving the guide seat downwards until each positioning plate can reliably adhere to and abut against the inner walls of each side of the inner carton. This utilizes the positioning plates to form reliable side support and a stable structural positioning for each side wall of the inner carton, preventing side collapse or bending damage to the inner carton during subsequent carton assembly. Simultaneously, each guide arm is in an outward-opening state to ensure that each side edge of the inner carton can be smoothly inserted into the guide gap formed between the guide arm and the guide seat from bottom to top. Then, align the bottom opening of the outer cardboard box to be assembled from top to bottom and fit it onto the top of the guide seat, gradually lowering the outer cardboard box until the bottom ends of each side edge of the outer cardboard box contact the outer side wall of the guide arm. As the outer cardboard box continues to move downwards, the guide arm is gradually retracted by the downward force exerted by the outer cardboard box until it can smoothly slide into the inner cavity of the outer cardboard box. Thus, as the outer cardboard box continues to move downwards, the side edges of the inner cardboard box located inside the guide arm are completely within the structural range of the side edges of the outer cardboard box located outside the guide arm, thereby utilizing the guide arm as an inner... The alignment and assembly guide of the inner and outer carton side edges smoothly completes the alignment, adaptation, and positioning assembly of the side edges of the inner and outer cartons. At the same time, it maintains reliable positioning support for each side wall of the inner carton by each positioning plate. As the outer carton moves down, the lateral fitting space formed by the guide arm located between the inner and outer cartons allows each side wall of the outer carton to be smoothly aligned and fitted onto the outer side wall of the inner carton. This completes the overall insertion of the inner carton into the inner cavity of the outer carton, realizing the overall circumferential alignment and longitudinal fitting assembly of the inner and outer cartons. The entire assembly process of the double-layer carton relies on the coordinated operation of the face positioning component and the edge guiding component to achieve precise positioning and smooth guidance of the side wall face structure and edge structure of the inner and outer cartons. The guide arm and positioning plate ensure sufficient structural protection for the inner and outer cartons, effectively preventing bending or damage to the inner and outer cartons during assembly. This significantly improves the structural reliability and assembly quality of the double-layer carton assembly, and makes the overall assembly process simpler and smoother, with corresponding improvements in assembly accuracy and efficiency.

[0022] In another preferred embodiment of this utility model, a plurality of face guide components are further provided on the outer side wall of the guide seat, and the face guide components are arranged in a corresponding manner to the face positioning components. The face guide component includes two guide support plates protruding from the outer side wall of the guide seat. The two guide support plates are arranged in a horizontal direction and are clearance-fitted. The face guide component also includes a guide roller that is horizontally arranged and can rotate on a fixed axis. The two ends of the guide roller are respectively rotatably connected to the top of the two guide support plates through ball bearings. In the face guide component and the face positioning component arranged in a corresponding manner, the horizontal axis of the guide roller is higher than the top edge of the positioning plate. The outer edge of the guide roller protrudes from the outer side wall of the inner carton, and the guide roller can fit against and roll to adapt to the inner side wall of the outer carton. After the guide seats and face positioning components are positioned in the inner carton, each positioning plate is reliably supported on the inner side wall of the inner carton. At this time, each guide roller is positioned above the corresponding positioning plate, that is, each guide roller is located above the top opening of the inner carton, and each guide roller corresponds vertically to each side wall of the inner carton. Thus, during the process of fitting the outer carton from top to bottom onto the outer carton, the inner side wall of the outer carton can contact and roll with each guide roller, allowing each guide roller to rotate synchronously along its fixed axis as the outer carton moves downwards. This arrangement of guide rollers protruding from the top opening of the inner carton, combined with the rolling action between the guide rollers and the outer carton, ensures smooth downward movement of the outer carton, further improving the efficiency of fitting the outer carton from top to bottom onto the outer carton, and consequently increasing the assembly efficiency of the double-layer carton assembly. Furthermore, by utilizing the matching structure where the outer edge of the guide roller protrudes horizontally from the side wall of the inner carton, and combining the guide roller as a rolling adaptation contact component with the inner wall of the outer carton, rigid contact or friction between the outer and inner cartons is effectively avoided during carton assembly. This further prevents collisions and wear between the inner and outer cartons during assembly, making the assembly process of the double-layer carton assembly safer and more stable, and resulting in a more regular and reliable structure for the assembled double-layer carton assembly.

[0042] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] It should be noted in advance that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" in this utility model should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

Similarly, "below," "under," and "beneath" for the first feature and the second feature include the first feature being directly below or diagonally below the second feature, or simply indicating that the first feature is at a lower horizontal level than the second feature. The terms "above," "below," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0046] In a specific embodiment, the double-layer carton assembly guide device provided by this utility model, such as... Figure 1 and Figures 6 to 8As shown, it includes a guide seat 10 that can be inserted into the inner carton 21 from top to bottom. The height direction of the guide seat 10 is consistent with the vertical direction. Several face positioning components are provided on the side outer wall of the guide seat 10. The face positioning components include a positioning plate 11 that extends obliquely along the height direction of the guide seat 10. The bottom edge of the positioning plate 11 is pressed against the side outer wall of the guide seat 10, and the outer wall of the positioning plate 11 can be attached to and abut against the side inner wall of the inner carton 21.

[0047] A ridge guide assembly is provided at the junction of two adjacent outer walls on the side of the guide seat 10. The ridge guide assembly includes a guide arm 12 that is inclined along the height direction of the guide seat 10. The top end of the guide arm 12 is hinged to the guide seat 10. The inner side wall of the guide arm 12 is clearance-fitted with the guide seat 10 to form a guide gap 121 for the side ridge of the inner carton 21 to be inserted from bottom to top. The outer side wall of the guide arm 12 can fit and slide with the inner cavity side ridge of the outer carton 22.

[0048] In specific operation and use, such as Figure 2 As shown, the guide seat 10 is inserted into the top opening of the inner carton 21 to be assembled from top to bottom. The guide seat 10 is gradually moved downwards until each positioning plate 11 can reliably fit and abut against the inner side walls of the inner carton 21. This utilizes the positioning plates 11 to form reliable side support and stable structural positioning for the side walls of the inner carton, preventing side collapse or bending damage to the inner carton 21 during subsequent carton assembly. At the same time, each guide arm 12 is in an outward-opening state to ensure that each side edge of the inner carton 21 can be smoothly inserted into the guide gap 121 formed between the guide arm 12 and the guide seat 10 from bottom to top.

[0049] Then, as Figure 3 As shown, the bottom opening of the outer cardboard box 22 to be assembled is aligned and fitted onto the top of the guide seat 10 from top to bottom, and the outer cardboard box 22 is gradually moved downwards until the bottom ends of each side edge of the outer cardboard box 22 contact the outer side wall of the guide arm 12. Then, as the outer cardboard box 22 continues to move downwards, the guide arm 12 is gradually retracted by the downward force exerted by the outer cardboard box 22 until the guide arm 12 retracts smoothly into the inner cavity of the outer cardboard box 22. Thus, as the outer cardboard box 22 continues to move downwards, each side edge of the inner cardboard box 21 located inside the guide arm 12 is completely within the structural range of each side edge of the outer cardboard box 22 located outside the guide arm 12. Therefore, the guide arm 12 serves as a guide for the alignment and assembly of the side edges of the inner cardboard box 21 and the outer cardboard box 22, smoothly completing the alignment, adaptation, and positioning assembly of the side edges of the inner cardboard box 21 and the outer cardboard box 22.

[0050] Simultaneously, each positioning plate 11 maintains reliable positioning support for each side wall of the inner cardboard box 21. As the outer cardboard box 22 continues to move downwards, the lateral fitting space formed by the guide arm 12 located between the inner cardboard box 21 and the outer cardboard box 22 is utilized, such as... Figure 4 As shown, this allows the side walls of the outer cardboard box 22 to be smoothly aligned and fitted onto the outer side walls of the inner cardboard box 21, thus completing the overall insertion of the inner cardboard box 21 into the inner cavity of the outer cardboard box 22. This achieves overall circumferential alignment and longitudinal fitting assembly of the inner cardboard box 21 and the outer cardboard box 22. After the double-layer cardboard box assembly guide device is removed through the top opening of the double-layer cardboard box assembly, the result is as follows: Figure 5 The double-layer cardboard box assembly shown.

[0051] During the assembly of the double-layer carton, the face positioning component and the edge guiding component work together to achieve precise positioning and smooth guidance of the side wall face structure and edge structure of the inner carton 21 and the outer carton 22. The guide arm 12 and the positioning plate 11 ensure sufficient structural protection for the inner and outer cartons, effectively preventing bending or damage to the inner carton 21 and the outer carton 22 during assembly. This significantly improves the structural reliability and assembly quality of the double-layer carton assembly, and makes the overall assembly process simpler and smoother, with corresponding improvements in assembly accuracy and efficiency.

[0052] Generally, both the inner cardboard box 21 and the outer cardboard box 22 are cuboid in shape. The assembled double-layer cardboard box assembly is also a double-layered cuboid structure. Therefore, for typical working conditions, the guide seat 10 provided in this solution is also as described. Figure 9 The rectangular structure shown is adapted to the inner carton 21 and the outer carton 22. Correspondingly, each face positioning component, edge guiding component and face guiding component are also arranged on the four sides of the guide seat 10 with the rectangular structure.

[0053] It is easy to understand that if the inner carton 21 and the outer carton 22 are cylindrical, triangular prism or other shapes in actual application, the guide seat 10 should also adopt a three-dimensional shape that can be adapted to the inner carton 21 and the outer carton 22, so as to ensure the corresponding carton positioning, support and guiding effect, and ensure the alignment accuracy and operation efficiency when the inner carton 21 and the outer carton 22 are assembled.

[0054] Furthermore, it should be noted that, considering the placement direction of double-layer cartons under normal circumstances, the height direction of the guide seat 10 mentioned in this solution can be understood as the vertical direction. The height directions of the inner carton 21 and the outer carton 22 can also be understood accordingly. The up and down movement directions involved in the solution can be understood based on the arrangement direction of the corresponding components, and will not be elaborated further.

[0055] In specific operation, after the inner carton 21 and outer carton 22 of the double-layer carton assembly are assembled, the double-layer carton assembly guide device can be pulled out through the top opening of the double-layer carton assembly to realize the complete assembly of the inner carton 21 and outer carton 22 of the current double-layer carton assembly. The removed double-layer carton assembly guide device can be placed at the next inner carton 21 that needs to be assembled so as to carry out the assembly operation of the next double-layer carton assembly.

[0056] Specifically, based on Figure 1 and combined Figures 6 to 9 As shown, a number of face guide components are also provided on the outer side wall of the guide seat 10. The face guide components and face positioning components are arranged in a corresponding manner. The face guide component includes two guide support plates 131 protruding from the outer side wall of the guide seat 10. The two guide support plates 131 are arranged in a horizontal direction and are fitted with a clearance. The face guide component also includes a guide roller 13 that is horizontally arranged and can rotate on a fixed axis. The two ends of the guide roller 13 are respectively rotatably connected to the top of the two guide support plates 131 through ball bearings 132. In the face guide component and face positioning component arranged in a corresponding manner on the same side wall of the guide seat 10, the horizontal axis of the guide roller 13 is higher than the top edge of the positioning plate 11. The outer edge of the guide roller 13 protrudes from the outer side wall of the inner carton 21, and the guide roller 13 can fit and roll with the inner side wall of the outer carton 22.

[0057] It should be pointed out that, such as Figures 6 to 8 As shown, in practical applications, the face guide assembly may also include a horizontally arranged guide shaft 133, with both ends of the guide shaft 133 fixedly connected to the guide support plate 131. The guide roller 13 is coaxially sleeved on the outer periphery of the guide shaft 133. The inner ring of the ball bearing 132 is linkedly sleeved on the guide shaft 133, while the outer ring of the ball bearing 132 is linkedly connected to the inner ring of the guide support plate 131. In this way, the guide roller 13 can rotate around the guide shaft 133. Alternatively, the face guide assembly may not require the guide shaft 133. Instead, the inner ring of the ball bearing 132 can be directly fixed to the guide support plate 131 with bolts, and the outer ring can be linkedly connected to the internal component mating mechanism of the guide roller 13. This will also achieve the fixed-axis rotation of the guide roller 13.

[0058] After the guide seat 10 and the face positioning assembly are positioned in the inner carton 21, each positioning plate 11 is reliably supported on the inner side wall of the inner carton 21. At this time, each guide roller 13 is located above each positioning plate 11 in a corresponding manner. That is, each guide roller 13 is located above the top opening of the inner carton 21, and each guide roller 13 corresponds to each side wall of the inner carton 21 in the vertical direction. Thus, during the process of fitting the outer cardboard box 22 from top to bottom onto the outer cardboard box 21, the inner side wall of the outer cardboard box 22 can contact and roll with each guide roller 13, thereby enabling each guide roller 13 to rotate synchronously on a fixed axis as the outer cardboard box 22 moves downward. By utilizing the arrangement of the guide roller 13 protruding from the top opening of the inner cardboard box 21, and in conjunction with the rolling cooperation between the guide roller 13 and the outer cardboard box 22, the outer cardboard box 22 can move downward smoothly, thereby further improving the efficiency of fitting the outer cardboard box 22 from top to bottom onto the outer cardboard box 21, and correspondingly improving the assembly efficiency of the double-layer cardboard box assembly.

[0059] Furthermore, by utilizing the matching structure where the outer edge of the guide roller 13 protrudes horizontally from the side outer wall of the inner carton 21, and combining the guide roller 13 as a rolling adaptation contact component with the inner wall of the outer carton 22, rigid contact or friction between the outer carton 22 and the inner carton 21 is effectively avoided during the carton assembly process. This further prevents collisions and wear between the inner carton 21 and the outer carton 22 during the assembly process, thereby making the assembly process of the double-layer carton assembly safer and more stable, and the structure of the double-layer carton assembly after assembly is more regular and reliable.

[0060] Considering the box adaptation requirements under most working conditions, the outer edge of the guide roller 13 protrudes horizontally from the top opening of the inner carton 21 by a size of 3~5mm. Of course, the protrusion of the outer edge of the guide roller 13 relative to the inner carton 21 can be adjusted according to the actual application requirements. In principle, as long as it can ensure smooth and reliable assembly of the outer carton 22 and the inner carton 21, it is acceptable.

[0061] More specifically, such as Figure 9The guide support plate 131 shown is vertically disposed on the outer side wall of the guide seat 10, and the width of the guide support plate 131 increases from bottom to top. The outer edge of the side of the guide support plate 131 is tightly fitted and welded to the inner wall of the positioning plate 11. The width of the guide support plate 131 here refers to the horizontal dimension between the edge of the guide support plate 131 away from the guide seat 10 and the edge of the guide support plate 131 that is fitted to the guide seat 10. This gradual increase in dimension from bottom to top allows the guide support plate 131 to form a generally inverted triangular structure that protrudes from the side wall of the guide seat 10 and is wider at the top and narrower at the bottom. Thus, by using the guide support plate 131 as a structural support component and direct connecting part of the positioning plate 11, not only can the inclined edge of the inverted triangular structure of the guide support plate 131 itself be used as the fitting positioning and welding assembly reference for the positioning plate 11, so that the positioning plate 11 can form a more reliable inclined extension structure, thereby ensuring that the bottom end of the positioning plate 11 can fit more closely to the guide seat 10, so that the bottom of the positioning plate 11 can be inserted into the inner carton 21 more smoothly, but also the positioning plate 11 can gradually move away from the guide seat 10 from bottom to top, forming an upwardly expanding extension structure, so that as the guide seat 10 moves down, the positioning plate 11 can gradually fit fully and reliably abut against the inner side wall of the inner carton 21.

[0062] Correspondingly, the positioning plate 11 has several process holes 111. While ensuring the structural strength of the positioning plate 11, these process holes 111 can further reduce the weight of the positioning plate 11, making the structure of the positioning plate 11 lighter. At the same time, the presence of these process holes 111 can effectively reduce the contact area between the main extension surface of the positioning plate 11 and the side inner wall of the inner carton 21, optimize the stress distribution at the side wall during the carton assembly process, and thus further avoid jamming or wear between the inner carton 21 and the outer carton 22 during the assembly process.

[0063] On the other hand, combining Figure 9 and Figure 10 As shown, the edge guide assembly includes two guide supports 122 protruding from the outer wall of the guide seat 10. The two guide supports 122 are aligned horizontally and fitted with a clearance. The edge guide assembly also includes a horizontally arranged guide hinge shaft 123. The two ends of the guide hinge shaft 123 are respectively fixedly inserted into the outer ends of the two guide supports 122. The top end of the guide arm 12 has a hinge hole 124 extending horizontally. The guide hinge shaft 123 is inserted into the hinge hole 124 and rotates to adapt, so that the guide arm 12 is hinged to the guide hinge shaft 123. The guide supports 122 can provide reliable structural support for the guide hinge shaft 123 and the guide arm 12. On this basis, using the guide hinge shaft 123 as the hinge reference component of the guide arm 12 not only ensures the assembly strength of the guide arm 12, but also makes its rotation / swing around the guide hinge shaft 123 smoother and more stable.

[0064] Furthermore, the edge guide assembly also includes a buffer reset member arranged on the inner side of the guide arm 12 to push the guide arm 12 outward. The buffer reset member can reciprocate and extend along the hinge opening and closing direction of the guide arm 12. In the non-working state, the buffer reset member is in the extended state to support the guide arm 12 around the guide hinge axis 123, ensuring that the space at the guide gap 121 on the inner side of the guide arm 12 is sufficient for the edge of the inner carton 21 to be inserted. When the carton is assembled, as the outer carton 22 contacts the guide arm 12 and gradually moves downward, the guide arm 12 gradually retracts. At this time, the buffer reset member is gradually contracted by the pressure from the retraction of the guide arm 12, thereby providing structural buffer for the retraction process of the guide arm 12, making the retraction action of the guide arm 12 more stable and smooth.

[0065] Generally, the buffer reset component is a torsion spring 125 integrated and mounted on the guide hinge shaft 123. This torsion spring 125 can be fitted onto the outer circumferential surface of the guide hinge shaft 123, or it can be positioned at the connection between the guide hinge shaft 123 and the guide arm 12. The torsion spring 125 has a simple structure, and its elastic deformation process is smooth and reliable, effectively ensuring structural buffering and elastic support for the guide arm 12. Alternatively, a compression spring or rubber buffer component snapped between the guide arm 12 and the guide seat 10 can also be used as the specific application type of the buffer reset component. Operators can flexibly select the type of buffer reset component based on specific working conditions. In principle, any component that meets the actual application needs of the double-layer carton assembly guide device is acceptable.

[0066] Correspondingly, a guide shaft 133 set 1231 can be arranged at the top of the guide arm 12, and a hinge hole 124 passes through the middle of the guide shaft 133 set 1231. In this way, the torsion spring 125 and the guide hinge shaft 123 and other moving parts can be adapted to the guide shaft 133 set 1231 to avoid these moving parts from interfering with or damaging the main structure of the guide arm 12, thereby improving the service life and operational reliability of the related parts of the guide arm 12.

[0067] Furthermore, please continue to refer to... Figure 10The guide arm 12 has a bent portion 126 protruding in the middle towards the direction away from the guide seat 10. An assembly section 127 is formed between the bent portion 126 and the top end of the guide arm 12, and a guide section 128 is formed between the bent portion 126 and the bottom end of the guide arm 12. The angle between the extension axis of the assembly section 127 and the extension axis of the guide section 128 is an obtuse angle. The bending section 126 works in coordination with the guide sections 128 and assembly sections 127 on both sides, so that the guide arm 12 itself forms a double-segment small-amplitude directional extension structure. The assembly section 127 is used as a part that is adapted to the guide hinge shaft 123, ensuring that the amplitude of the hinge structure swinging and rotating meets the action requirements. At the same time, the guide section 128 is used to form a part that can fit more closely with the side edge of the inner carton 21, so that the retraction amplitude of the guide arm 12 is greater, thereby avoiding structural interference or obstruction between the guide arm 12 and the outer carton 22 during the assembly of the carton. This makes the assembly of the inner carton 21 and the outer carton 22 smoother and more efficient.

[0068] In addition, an inner positioning groove 129 is recessed on the inner sidewall of the guide arm 12 to fit snugly against the side edge of the inner carton 21. This inner positioning groove 129 can fully fit against the outer wall of the side edge of the inner carton 21, thereby further optimizing the folding effect of the guide arm 12 and making the alignment and assembly of the outer carton 22 and the inner carton 21 smoother and more efficient.

[0069] Correspondingly, an outer positioning protrusion 120 is provided on the outer side wall of the guide arm 12 to fit snugly against the inner cavity side edge of the outer carton 22. This outer positioning protrusion 120 can fully fit snugly against the inner surface of the side edge of the outer carton 22, thereby further optimizing the sliding fit between the guide arm 12 and the outer carton 22, making the downward movement of the outer carton 22 and the alignment and assembly process between the outer carton 22 and the inner carton 21 smoother and more efficient.

[0070] In fact, in practical applications, the guide arm 12 can be processed from V-shaped angle steel. In this way, the V-shaped groove of the V-shaped angle steel can be used as the inner positioning groove 129 in this solution, and the V-shaped protrusion of the V-shaped angle steel can be used as the outer positioning protrusion 120 in this solution, thereby further improving the structural integration and structural strength of the guide arm 12, and making the processing and forming of the guide arm 12 simpler, and reducing the manufacturing cost accordingly.

[0071] Furthermore, it should be noted that in practical applications, the main components of the double-layer carton assembly guide device, such as the guide seat 10, positioning plate 11, and guide arm 12, are all made of stainless steel. This ensures the structural strength and operational reliability of each component while improving its working condition tolerance, thereby making the double-layer carton assembly guide device more durable.

[0072] During actual assembly, the guide support 122 and the guide plate 131 are welded and fixed to the side wall of the guide seat 10 to ensure the structural strength of the relevant mating parts after assembly, and to improve the overall component integration and reliability of the double-layer carton assembly guide device.

[0073] In summary, the double-layer carton assembly guide device provided in this utility model allows the guide seat to be inserted into the top opening of the inner carton to be assembled from top to bottom during operation. The guide seat is then moved downwards until each positioning plate can reliably adhere to and abut against the inner walls of each side of the inner carton. This utilizes the positioning plates to form reliable side support and a stable structural positioning for each side wall of the inner carton, preventing side collapse or bending damage to the inner carton during subsequent assembly. Simultaneously, each guide arm is in an outward-opening state to ensure that each side edge of the inner carton can be smoothly inserted into the guide gap formed between the guide arm and the guide seat from bottom to top. Then, align the bottom opening of the outer cardboard box to be assembled from top to bottom and fit it onto the top of the guide seat, gradually lowering the outer cardboard box until the bottom ends of each side edge of the outer cardboard box contact the outer side wall of the guide arm. As the outer cardboard box continues to move downwards, the guide arm is gradually retracted by the downward force exerted by the outer cardboard box until it can smoothly slide into the inner cavity of the outer cardboard box. Thus, as the outer cardboard box continues to move downwards, the side edges of the inner cardboard box located inside the guide arm are completely within the structural range of the side edges of the outer cardboard box located outside the guide arm, thereby utilizing the guide arm as an inner... The alignment and assembly guide of the inner and outer carton side edges smoothly completes the alignment, adaptation, and positioning assembly of the side edges of the inner and outer cartons. At the same time, it maintains reliable positioning support for each side wall of the inner carton by each positioning plate. As the outer carton moves down, the lateral fitting space formed by the guide arm located between the inner and outer cartons allows each side wall of the outer carton to be smoothly aligned and fitted onto the outer side wall of the inner carton. This completes the overall insertion of the inner carton into the inner cavity of the outer carton, realizing the overall circumferential alignment and longitudinal fitting assembly of the inner and outer cartons. The entire assembly process of the double-layer carton relies on the coordinated operation of the face positioning component and the edge guiding component to achieve precise positioning and smooth guidance of the side wall face structure and edge structure of the inner and outer cartons. The guide arm and positioning plate ensure sufficient structural protection for the inner and outer cartons, effectively preventing bending or damage to the inner and outer cartons during assembly. This significantly improves the structural reliability and assembly quality of the double-layer carton assembly, and makes the overall assembly process simpler and smoother, with corresponding improvements in assembly accuracy and efficiency.

Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
