[0001] The present invention relates to the technical field of carton detection, and in particular to a compression detection device for producing corrugated paper packaging boxes and a use method thereof. Background Art

[0002] Carton compression testing is an important step in evaluating the compression resistance of cartons. It is of great significance to ensure the stability and safety of cartons during transportation and storage. The main purpose of carton compression testing is to evaluate the compression resistance of cartons when subjected to external pressure to ensure that the cartons can protect the contents from damage. Through testing, we can understand the load-bearing capacity, deformation characteristics and possible failure modes of the cartons.

[0003] For example, the patent application number published on the China Patent Network is: 202320118158.3, and the patent name is: A carton compression detection device, including a body, a storage table arranged on the body and used to place cartons, and a pressing component arranged on the body for applying pressure to the carton, and also includes a positioning component arranged on the storage table, the positioning component includes a positioning plate arranged on the storage table and a moving part for driving the positioning plate to move. This application has the effect of improving the accuracy of compression detection and improving the efficiency of carton detection.

[0004] However, the existing compression resistance detection device has a relatively simple detection method, which is mainly performed by direct downward pressure. Cartons that lack support on the outside are prone to abnormal deformation when directly pressed down on the top, which affects the compression resistance detection effect of the carton.

[0005] Therefore, it is necessary to design and modify the compression testing device and the method of using the compression testing device for corrugated paper packaging box production. Summary of the invention

Cartons that lack support on the outside are prone to abnormal deformation when directly pressed down on the top, resulting in the carton The compression resistance detection effect is affected.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a compression resistance detection device for corrugated paper packaging box production and a method of using the same, comprising a base; A rack fixedly connected to the top of the base; The internal transmission of the frame is connected with a pressure plate, and the top of the base is provided with a carton located at the bottom of the pressure plate, and connecting blocks are provided on both sides of the top of the pressure plate. The interior of the connecting block is movably connected with a shaft rod through a bearing, and the surface of the shaft rod is fixedly connected with a support plate, and the side of the support plate away from the shaft rod extends to the outside of the carton and contacts with the surface of the carton. The surface of the frame is provided with a transmission structure, and the transmission structure can control the automatic swing of the support plate.

[0008] As a preferred embodiment of the present invention, the transmission structure includes a guide frame fixedly connected to both sides of the frame, the top of the guide frame is arranged to be inclined, and both ends of the shaft rod are fixedly connected with a force plate, and the side of the force plate away from the shaft rod is in contact with the surface of the guide frame, and when the force plate is located on the inclined surface at the top of the guide frame, it can swing inward and use the shaft rod to carry the support plate out of contact with the carton.

[0009] As a preferred embodiment of the present invention, connecting frames are provided on both sides of the top of the pressure plate, the connecting block is fixedly connected to the surface of the connecting frame, the surface of the connecting frame is fixedly connected to a transmission plate, both sides of the top of the pressure plate are fixedly connected to vertical plates located outside the transmission plate, the inner side of the vertical plate is fixedly connected to a guide rod, and the transmission plate is sleeved on the surface of the guide rod and is slidably connected to the guide rod.

[0010] As a preferred embodiment of the present invention, nuts are threadedly connected to both sides of the guide rod surface, and the nuts are located on the outside of the transmission plate and squeeze the transmission plate to position.

[0011] As a preferred embodiment of the present invention, one end of the force-bearing plate away from the shaft rod is movably connected to a roller via a pin, and an outer surface of the roller is in contact with a surface of the guide frame.

[0012] As a preferred embodiment of the present invention, a bracket is fixedly connected to the outer side of the support plate, and the side of the bracket away from the support plate is movably connected to a side plate through a pin shaft, and the side of the side plate away from the bracket extends to the left and right sides of the carton and contacts the surface of the carton.

[0013] As a preferred embodiment of the present invention, the outer side of the connecting block and one end of the side plate close to the bracket are fixedly connected with helical gears, and the helical gears are meshed with each other.

[0014] A compression resistance detection device for corrugated paper packaging box production and a method of using the same, comprising the following steps: S1: Start the pressurizing mechanism, so that the pressurizing plate starts to move downward. When the pressurizing plate moves downward, the supporting plate is driven to move downward together through the connecting block and the shaft rod, thereby applying pressure to the carton; S2: As the pressure plate continues to descend, the force plate gradually contacts the inclined surface of the guide frame. Since the top of the guide frame is set to be inclined, the force plate will be pushed inward after contacting the inclined surface, causing the force plate to drive the support plate to swing inward through the shaft. When the force plate is completely located on the inclined surface of the guide frame, the support plate swings from a horizontal state to a vertical state. At this time, the carton is directly pressed by the pressure plate, and the support plate is located outside the carton to support the carton. The pressure plate continues to move downward until a predetermined pressure value is reached or the carton is damaged. S3: During this process, the pressure value applied to the carton and the deformation of the carton are monitored by sensors or instruments; S4: During the swinging process of the support plate, the bevel gear on the surface of the support plate can be affected by the bevel gear fixed on the outside of the connecting block to carry the side plate to swing inward. When the inner side of the side plate contacts the left and right sides of the carton respectively, the carton can be further supported. When the pressure plate moves upward, the force plate gradually separates from the inclined surface of the guide frame and returns to its original position under the action of the shaft. At the same time, the support plate also moves upward together with the pressure plate through the shaft and the connecting block and returns to the initial position. After the device is reset, the tested carton can be taken out and a new carton can be put in for the next compression test.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention ensures the stability and accuracy of the detection process by setting a fixed connection between the frame, the pressure plate, the base and other components. The relative position setting of the pressure plate and the carton enables the compression test to act directly on the carton, effectively evaluating the compression performance of the carton.

[0016] 2. The present invention realizes the automatic swinging function of the support plate through the design of the transmission structure, especially the coordination of the inclined top of the guide frame and the force-bearing plate. During the pressurizing process, the force-bearing plate descends with the pressurizing plate, and when it contacts the inclined surface of the guide frame, it can swing inward, thereby driving the support plate to contact the carton.

[0017] 3. The present invention provides stable support and guidance for the pressure plate through the combined design of the connecting frame, the transmission plate, the vertical plate and the guide rod. The sliding connection between the transmission plate and the guide rod allows the user to flexibly adjust the spacing between the support plates to meet the support requirements of cartons of different sizes.

[0018] 4. The nut design of the present invention is not only used to fix the position of the transmission plate, but also increases the friction between the transmission plate and the guide rod through the extrusion effect, thereby preventing the transmission plate from slipping during the pressurization process.

[0019] 5. The present invention reduces the friction between the force-bearing plate and the guide frame through the combined design of the force-bearing plate and the roller, so that the force-bearing plate can swing inward more smoothly when contacting the inclined surface of the guide frame.

[0020] 6. The present invention provides additional support for the carton through the design of the bracket and side plate outside the support plate. The contact between the side plate and the surface of the carton further limits the deformation of the carton during the pressurization process, making the detection result more accurate.

[0021] 7. The present invention realizes synchronous movement between the support plate and the side plate by meshing the bevel gears on the outer side of the connecting block and the side plate near one end of the bracket, ensuring that the carton is subjected to uniform pressure distribution during the inspection process and saving the additional operation step of rotating the side plate.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figures 1 to 6 As shown, the present invention provides a compression resistance detection device for corrugated paper packaging box production and a method of using the same, comprising a base 1; A frame 2 fixedly connected to the top of the base 1; The internal transmission of the frame 2 is connected with a pressure plate 3, and the top of the base 1 is provided with a carton 4 located at the bottom of the pressure plate 3, and connecting blocks 5 are provided on both sides of the top of the pressure plate 3.

The surface of the frame 2 is provided with a transmission structure 8, and the transmission structure 8 can control the automatic swing of the support plate 7.

[0026] refer to Figure 3 The transmission structure 8 includes a guide frame 9 fixedly connected to both sides of the frame 2, the top of the guide frame 9 is set to be inclined, and both ends of the shaft 6 are fixedly connected with a force plate 10, and the side of the force plate 10 away from the shaft 6 is in contact with the surface of the guide frame 9. When the force plate 10 is located on the inclined surface at the top of the guide frame 9, it can swing inward and use the shaft 6 to carry the support plate 7 to break contact with the carton 4.

[0027] As a technical optimization solution of the present invention, the automatic swinging function of the support plate 7 is realized through the design of the transmission structure 8, especially the cooperation between the inclined top of the guide frame 9 and the force-bearing plate 10. During the pressurizing process, the force-bearing plate 10 descends with the pressurizing plate 3, and when it contacts the inclined surface of the guide frame 9, it can swing inward, thereby driving the support plate 7 to contact the carton 4.

[0029] As a technical optimization solution of the present invention, the combined design of the connecting frame 11, the transmission plate 12, the vertical plate 13 and the guide rod 14 provides stable support and guidance for the pressure plate 3. The sliding connection between the transmission plate 12 and the guide rod 14 allows users to flexibly adjust the spacing between the support plates 7 to meet the support requirements of cartons 4 of different sizes.

[0030] refer to Figure 4 Both sides of the surface of the guide rod 14 are threadedly connected with nuts 15, and the nuts 15 are located on the outside of the transmission plate 12 and squeeze the transmission plate 12 to position.

[0031] As a technical optimization solution of the present invention, the design of the nut 15 is not only used to fix the position of the transmission plate 12, but also increases the friction between the transmission plate 12 and the guide rod 14 through the extrusion effect, thereby preventing the transmission plate 12 from slipping during the pressurization process.

[0032] refer to Figure 3 One end of the force-bearing plate 10 away from the shaft 6 is movably connected to a roller 16 through a pin, and the outer surface of the roller 16 contacts the surface of the guide frame 9 .

[0033] As a technical optimization solution of the present invention, the friction between the force-bearing plate 10 and the guide frame 9 is reduced through the combined design of the force-bearing plate 10 and the roller 16, so that the force-bearing plate 10 can swing inward more smoothly when contacting the inclined surface of the guide frame 9.

[0034] refer to Figure 6 A bracket 17 is fixedly connected to the outer side of the support plate 7, and a side plate 18 is movably connected to the side of the bracket 17 away from the support plate 7 through a pin shaft. The side plate 18 extends to the left and right sides of the carton 4 away from the bracket 17 and contacts the surface of the carton 4.

[0035] As a technical optimization solution of the present invention, the bracket 17 and the side panel 18 on the outside of the support plate 7 are designed to provide additional support for the carton 4. The contact between the side panel 18 and the surface of the carton 4 further limits the deformation of the carton 4 during the pressurization process, making the detection result more accurate.

[0036] refer to Figure 6 The outer side of the connecting block 5 and one end of the side plate 18 close to the bracket 17 are fixedly connected with a bevel gear 19, and the bevel gears 19 are meshed with each other.

[0037] As a technical optimization solution of the present invention, the outer side of the connecting block 5 and the bevel gear 19 on the side plate 18 close to the bracket 17 are meshed with each other to achieve synchronous movement between the support plate 7 and the side plate 18, thereby ensuring that the carton 4 is subjected to uniform pressure distribution during the inspection process and saving the additional operation step of rotating the side plate 18.

[0038] refer to Figure 1 A compression testing device for corrugated paper packaging box production and a method for using the same include the following steps: S1: Start the pressurizing mechanism to make the pressurizing plate 3 start to move downward. When the pressurizing plate 3 moves downward, the supporting plate 7 is driven to move downward together through the connecting block 5 and the shaft rod 6, thereby applying pressure to the carton 4; S2: As the pressure plate 3 continues to descend, the force plate 10 gradually contacts the inclined surface of the guide frame 9. Since the top of the guide frame 9 is set to be inclined, the force plate 10 will receive an inward thrust after contacting the inclined surface, causing the force plate 10 to drive the support plate 7 to swing inward through the shaft 6. When the force plate 10 is completely located on the inclined surface of the guide frame 9, the support plate 7 swings from a horizontal state to a vertical state. At this time, the carton 4 is directly pressed by the pressure plate 3, and the support plate 7 is located outside the carton 4 to support the carton 4. The pressure plate 3 continues to move downward until a predetermined pressure value is reached or the carton 4 is damaged. S3: During this process, the pressure value applied to the carton 4 and the deformation of the carton 4 are monitored by a sensor or an instrument; S4: During the swinging process of the support plate 7, the bevel gear 19 on the surface of the support plate 7 can be affected by the bevel gear 19 fixed on the outside of the connecting block 5 to carry the side plate 18 to swing inward. When the inner side of the side plate 18 contacts the left and right sides of the carton 4 respectively, the carton 4 can be further supported. When the pressure plate 3 moves upward, the force plate 10 gradually separates from the inclined surface of the guide frame 9 and returns to its original position under the action of the shaft 6. At the same time, the support plate 7 also moves upward together with the pressure plate 3 through the shaft 6 and the connecting block 5 and returns to the initial position. After the device is reset, the tested carton 4 can be taken out and a new carton 4 can be put in for the next compression test.

[0039] When the pressure plate 3 is moved downward, the supporting plate 7 is driven downward by the connecting block 5 and the shaft 6, thereby applying pressure to the carton 4. As the pressure plate 3 continues to descend, the force plate 10 gradually contacts the inclined surface of the guide frame 9. Since the top of the guide frame 9 is arranged in an inclined shape, the force plate 10 is subjected to an inward thrust after contacting the inclined surface, causing the force plate 10 to drive the supporting plate 7 to swing inward through the shaft 6. When the force plate 10 is completely located on the inclined surface of the guide frame 9, the supporting plate 7 swings from a horizontal state to a vertical state. At this time, the carton 4 is subjected to direct pressure from the pressure plate 3, and the supporting plate 7 is located outside the carton 4 to support the carton 4. The pressure plate 3 continues to move downward until the carton 4 is lifted. Until a predetermined pressure value is reached or the carton 4 is damaged. During this process, the pressure value applied to the carton 4 and the deformation of the carton 4 can be monitored by sensors or instruments. During the swinging of the support plate 7, the bevel gear 19 on the surface of the support plate 7 can be affected by the bevel gear 19 fixed on the outside of the connecting block 5 to carry the side plate 18 to swing inward. When the inner side of the side plate 18 contacts the left and right sides of the carton 4 respectively, the carton 4 can be further supported. When the pressure plate 3 moves upward, the force plate 10 gradually separates from the inclined surface of the guide frame 9 and returns to its original position under the action of the shaft 6. At the same time, the support plate 7 also moves upward together with the pressure plate 3 through the shaft 6 and the connecting block 5 and returns to the initial position. After the device is reset, the tested carton 4 can be taken out and a new carton 4 can be put in for the next compression test.

[0040] In summary: the compression testing device for corrugated paper packaging box production and its use method, by setting a fixed connection between the frame 2, the pressure plate 3, the base 1 and other components, ensures the stability and accuracy of the detection process. The relative position setting of the pressure plate 3 and the carton 4 enables the compression test to act directly on the carton 4, effectively evaluating the compression performance of the carton 4.
