Description

Technical Field

[0001] The invention belongs to the technical field of bundling objects, in particular to a bundling device used in logistics. Background Art

[0002] In the modern logistics industry, automated strapping machines have become an indispensable key equipment in the cargo packaging process due to their efficient and stable strapping performance. Their working principle is to wrap the objects with straps, heat the straps with a heating plate, melt them and bond them together, thus achieving firm strapping.

[0003] However, during e-commerce shopping festivals such as "618" and "Double Eleven", the logistics industry ushered in a business peak, and the cargo handling volume showed an explosive growth. The strapping machine needs to run uninterruptedly for a long time, causing the heating plate to be in a continuous working state. During the repeated heating of the strap, the plastic strap will melt due to the heat and produce some impurities, which will adhere to the surface of the heating plate. As the use time increases, these impurities gradually accumulate, which not only affects the heat conduction efficiency of the heating plate, but also reduces the bonding quality of the strap, thereby affecting the strapping effect.

[0004] To ensure the quality of strapping, staff need to clean the heating plate regularly. However, currently, when cleaning the heating plate, the strapping machine must be suspended, which interrupts the continuity of logistics packaging and affects overall work efficiency.

[0005] In addition, when faced with stubborn dirt attached to the surface of the heating plate, operators usually enhance the cleaning effect by increasing the positive pressure between the scraper and the heating plate. According to the principle of friction, as the positive pressure increases, the friction between the scraper and the heating plate will continue to increase, which can easily cause the coating on the surface of the heating plate to be scratched, shortening its service life, and further affecting the heating performance and bundling quality.

[0006] To this end, the present invention provides a bundling device for logistics. Summary of the Invention

The liquid supply mechanism moistens the absorption layer with alcohol, and before scraping, the moist absorption layer is made to fit the contaminated surface of the heating plate. The alcohol softens the plastic residue, reducing the difficulty of cleaning. The alcohol evaporates and absorbs heat to reduce the surface temperature of the heating plate, avoiding damage to the equipment caused by high temperature during scraping. In addition, alcohol immersion reduces the friction coefficient between the scraper plate and the heating plate, reduces the friction during the scraping process, and reduces damage to the surface coating of the heating plate. The two mechanisms cooperate to achieve a more thorough cleaning effect, while protecting the heating plate and extending its service life, achieving the dual effects of improving cleaning quality and protecting equipment.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figures 1 to 8 As shown, the strapping device for logistics described in the present invention includes a strapping assembly, a heating mechanism, a power supply mechanism, a scraping mechanism, an impregnation mechanism and a liquid supply mechanism.

[0022] The strapping assembly includes a mounting shell 1 and a material guide gantry 3. The material guide gantry 3 is fixedly mounted on the upper end of the mounting shell 1. When strapping items, the items are placed under the material guide gantry 3. The strapping belt passes through the material guide gantry 3 and fits the surface of the item and is tightened. A control module and a motor are provided inside the mounting shell 1. A conveying roller group for conveying the strapping belt is provided inside the material guide gantry 3. A winding roller and a control panel for winding the strap are provided outside the mounting shell 1. When in use, the object is placed under the material guide gantry 3 until the strap binds the object.

[0023] The heating mechanism includes a heating plate 2 and a mounting tube 11. The mounting tube 11 is rotatably mounted on the inner wall of the mounting shell 1, and the heating plate 2 is movably arranged on one side of the mounting tube 11. The heating plate 2 utilizes the principle of resistance heating to heat the overlapping part of the bundle after bundling, thereby realizing hot-melt fixation of the overlapping part.

[0024] The power supply mechanism is used to maintain electrical connection between the power supply and the heating plate 2 after the heating plate 2 moves along the axis of the mounting tube 11; At least two heating plates 2 are provided along the axis of the mounting tube 11. In this embodiment, two heating plates 2 are provided, one of which is in heating operation and the other is in preparation operation. They cooperate with each other so that when plastic impurities are attached to the surface of the heating plate 2, the other can fill in the position. When the heating plate 2 is cleaned during the packaging production process, the machine can be operated without stopping and maintain smooth operation.

[0025] The scraping mechanism includes a scraping plate 29, a supporting plate 40 and an energy storage plate 30. The scraping plate 29 is made of elastic material and is fixedly installed on the outer wall of the supporting plate 40. The scraping plate 29 is used to scrape the surface of the heating plate 2 when dirt adheres to the surface of the heating plate 2 to achieve a cleaning effect.

[0026] When dirt adheres to the surface of the heating plate 2 and affects the hot melt quality, the contaminated heating plate 2 is controlled to shrink to the inside of the mounting shell 1 by rotating the mounting cylinder 11, and the heating plate 2 located in the mounting shell 1 moves to the heating position.

[0027] The supporting plate 40 is slidably arranged inside the mounting housing 1 , and the supporting plate 40 is slidably adjusted so as to slide horizontally. After the outer wall of the scraping plate 29 is in contact with the surface of the heating plate 2 , the heating plate 2 is scraped.

[0028] The energy storage plate 30 is elastically arranged on the outer wall of the supporting plate 40. The energy storage plate 30 is pulled away from the supporting plate 40. When the scraping plate 29 scrapes the heating plate 2, the energy storage plate 30 is released. The kinetic energy of the energy storage plate 30 when it hits the supporting plate 40 is transferred to the scraping plate 29 to assist in scraping and cleaning the surface of the heating plate 2.

[0029] The kinetic energy generated by the energy storage plate 30 hitting the carrier plate 40 after being released will be transmitted to the elastic scraping plate 29 through the carrier plate 40. Compared with uniform speed scraping, this instantaneous impact can produce high-frequency vibration or local stress concentration on stubborn dirt (such as sintered scale, hardened oil stains, etc.), making it easier to fall off from the surface of the heating plate 2. At the same time, the scraping plate 29 itself is made of elastic material and will produce a temporary deformation when it is hit, so that the contact pressure between it and the surface of the heating plate 2 increases instantly, changing the scraping angle. This dynamic change can cover the gaps or recessed areas that may be missed during uniform speed scraping, thereby achieving more comprehensive cleaning.

[0030] Traditional uniform-speed scraping often requires increasing the contact pressure between the scraper plate 29 and the heating plate 2 to remove stubborn dirt, resulting in increased wear of the scraper plate 29. The impact force of the energy storage plate 30 is intermittent, providing additional kinetic energy intermittently, and there is no need to continuously apply pressure to the scraper plate 29 toward the heating plate 2, thereby extending the service life of the scraper plate 29.

[0031] The impregnation mechanism includes a carrying frame 20 and an absorption layer 8 fixedly installed on the inner wall of the carrying frame 20, wherein the absorption layer 8 is made of a common sponge, and the liquid supply mechanism is used to wet the absorption layer 8 (since the strap is usually a PP or PET strap, the liquid for wetting the absorption layer 8 is alcohol). Before the scraper 29 scrapes the heating plate 2, the wetted absorption layer 8 is first controlled to fit the contaminated side of the heating plate 2, and the plastic residue on the surface of the heating plate 2 is wetted and preliminarily softened by alcohol, and then the scraper 29 scrapes the surface of the heating plate 2 to improve the cleaning quality.

[0032] In this embodiment, the surface of the heating plate 2 is moistened by the absorption layer 8, which not only softens the plastic residue on the surface of the heating plate 2, but also reduces the temperature of the surface of the heating plate 2 (alcohol itself evaporates and absorbs heat), thereby preventing the surface temperature of the heating plate 2 from being too high during scraping and cleaning, thereby providing protection. Finally, alcohol infiltration reduces the friction coefficient between the scraping plate 29 and the heating plate 2, reduces the friction force during the scraping process, and reduces damage to the surface coating of the heating plate 2.

[0033] A control rod 26 is fixedly mounted on the inner wall of the mounting tube 11 . The control rod 26 is a common electric telescopic rod. A mounting block 27 is fixedly mounted on the movable end of the control rod 26 . The mounting block 27 is moved by the movable end of the control rod 26 being telescopically moved.

[0034] A hinged plate 21 is rotatably mounted on the side wall of the mounting block 27 , a mounting bracket 4 is fixedly mounted on the bottom surface of the heating plate 2 , and the other end of the hinged plate 21 is rotatably connected to the bottom surface of the mounting bracket 4 . The number of hinged plates 21 set is the same as the number of heating plates 2 .

[0035] The outer wall of the mounting tube 11 is fixedly mounted with a guide frame 9, and the outer wall of the mounting frame 4 is fixedly mounted with a guide frame 22 which is slidably connected to the guide frame 9. The sliding cooperation between the guide frame 9 and the guide frame 22 limits the sliding trajectory of the mounting frame 4, thereby limiting the sliding trajectory of the heating plate 2.

[0036] An adjusting motor 25 is fixedly mounted on the inner wall of the mounting shell 1. The adjusting motor 25 controls the rotation of the mounting cylinder 11 through a transmission member. A gear is fixedly mounted on the output shaft of the adjusting motor 25. A gear ring meshing with the gear is provided on the outer wall of the mounting cylinder 11. The rotation of the mounting cylinder 11 is controlled by the adjusting motor 25.

[0037] When the heating plate 2 needs to be cleaned, the control rod 26 is first retracted to control the mounting block 27 to slide until the heating plate 2 is completely retracted to the inside of the mounting shell 1, and then the motor 25 is adjusted to drive the mounting cylinder 11 to rotate to control the positions of the two heating plates 2 to interchange, and finally the control rod 26 controls the mounting block 27 to slide in the opposite direction, and the heating plate 2 located above is in the working position.

[0038] As a preferred embodiment of the present invention, the power supply mechanism includes a support tube 7 , a power connection ring 13 , a contact plate 23 , a guide rod 24 and a terminal block 28 .

[0039] The support tube 7 is fixedly mounted on the inner wall of the mounting shell 1, and the power ring 13 is fixedly mounted on the outer wall of the support tube 7 and is electrically connected to the power supply. The power supply in this embodiment is a power module built into the strapping machine, and the power ring 13 is a wear-resistant graphite ring.

[0040] The terminal block 28 is fixedly mounted on the outer wall of the mounting frame 4 and is electrically connected to the heating plate 2 , and the two can be connected by an enameled wire.

[0041] The contact plate 23 is connected to the terminal plate 28 through an elastic member, and the outer wall of the contact plate 23 slides in contact with the radial outer wall of the connecting ring 13. The elastic member is a spring, and a connecting wire is provided between the terminal plate 28 and the contact plate 23. The elastic force of the spring pushes the contact plate 23 so that the contact plate 23 has a tendency to fit in contact with the outer wall of the connecting ring 13 in real time.

[0042] In order to prevent the contact plate 23 from being dislocated, the guide rod 24 is fixedly installed on the outer wall of the contact plate 23. The guide rod 24 passes through the mounting frame 4 and is slidably connected to the mounting frame 4. By setting the guide rod 24, the sliding trajectory of the contact plate 23 is limited, thereby preventing the contact plate 23 from being dislocated.

[0043] The axis of the support tube 7 coincides with the axis of the mounting tube 11 . During the rotation of the heating plate 2 and the mounting bracket 4 , the contact plate 23 remains in contact with the power ring 13 , thereby adapting to the power supply after the heating plate 2 rotates.

[0044] A support frame 14 is fixedly mounted on the inner wall of the mounting shell 1 , and a driving screw 18 is fixedly mounted on the outer wall of the support frame 14 . The driving screw 18 is connected to the support frame 14 via a bearing.

[0045] A travel motor 12 is fixedly mounted on the outer wall of the support frame 14 . The output shaft of the travel motor 12 is fixedly connected to the axial end of the drive screw 18 . The travel motor 12 is a common servo motor used to control the rotation of the drive screw 18 .

[0046] A threaded sleeve 34 is installed on the radial outer wall of the driving screw 18 through the cooperation of internal and external threads. A guide bar 15 is fixedly installed on the side wall of the support frame 14 and is slidably connected to the threaded sleeve 34. The rotation of the driving screw 18 is controlled by the travel motor 12, and the rotation of the threaded sleeve 34 is controlled by the cooperation of internal and external threads. The guide bar 15 is provided to prevent the threaded sleeve 34 from rotating along the axis of the driving screw 18.

[0047] An elastic plate 33 is fixedly installed on the radial outer wall of the threaded sleeve 34, and the other end of the elastic plate 33 is fixedly connected to the side wall of the supporting plate 40. The supporting plate 40 and the threaded sleeve 34 are connected through the elastic plate 33, and when the travel motor 12 controls the driving screw 18 to rotate, the supporting plate 40 is driven to slide, and then the scraping plate 29 is controlled to slide, thereby achieving cleaning of the heating plate 2.

[0048] In order to improve the stability of the energy storage plate 30 when sliding, a guide plate 39 is fixedly installed on the outer wall of the energy storage plate 30. One end of the guide plate 39 extends to the inner wall of the supporting plate 40 and is slidably connected to the supporting plate 40. By setting the guide plate 39, the sliding trajectory of the energy storage plate 30 is limited, thereby improving the sliding stability of the energy storage plate 30.

[0049] A connecting rod 31 is fixedly mounted on the side wall of the bearing plate 40 . The connecting rod 31 passes through the energy storage plate 30 . The side wall of the connecting rod 31 slides in contact with the inner wall of the energy storage plate 30 , thereby further improving the sliding stability of the energy storage plate 30 .

[0050] A limiting hook plate 37 is rotatably installed on the inner wall of the energy storage plate 30, and a limiting tooth plate 32 is fixedly installed on the side wall of the support frame 14. The side wall of the limiting hook plate 37 is provided with a rubber pad for increasing the resistance to the rotation of the limiting hook plate 37. When the limiting hook plate 37 and the limiting tooth plate 32 are engaged, the energy storage plate 30 and the bearing plate 40 are limited in one direction.

[0051] When the driving screw 18 rotates to control the threaded sleeve 34 and the supporting plate 40 to slide toward the moistened heating plate 2, the limiting hook plate 37 and the limiting tooth plate 32 engage to lock the energy storage plate 30 in one direction. As the supporting plate 40 slides, the elastic part between the supporting plate 40 and the energy storage plate 30 gradually stretches to store elastic potential energy, preparing for the tapping of the energy storage plate 30.

[0052] The outer wall of the connecting rod 31 is fixedly mounted with a pressing piece 38 for pressing the limit hook plate 37. As the distance between the bearing plate 40 and the energy storage plate 30 gradually increases, the pressing piece 38 gradually approaches the limit hook plate 37 until the pressing piece 38 presses the limit hook plate 37 to lift the limit hook plate 37. At this time, the limit hook plate 37 is affected by the friction force of the rubber pad and remains separated from the limit tooth plate 32. At this time, the energy storage plate 30 is affected by the elastic force and moves toward the bearing plate 40 and collides.

[0053] A reset plate 36 is fixedly installed on the outer wall of the connecting rod 31, and the limit hook plate 37 is located between the top pressure plate 38 and the reset plate 36. After the energy storage plate 30 hits the bearing plate 40, the reset plate 36 drives the limit hook plate 37 to rotate in the opposite direction until it engages with the limit tooth plate 32 again.

[0054] In order to keep the tapping operation smooth, the reset plate 36 is made of elastic material, and an elastic rubber pad is provided on the side of the guide plate 39 away from the energy storage plate 30. The elastic rubber pad is compressed during the collision. During this process, the limit hook plate 37 moves the limit hook plate 37 to engage with the limit tooth plate 32.

[0055] As a preferred embodiment of the present invention, a collection frame 10 is fixedly installed on the outer wall of the supporting plate 40, and a net bag is provided at the bottom of the collection frame 10. The collection frame 10 is located directly below the scraper plate 29. After the scraper plate 29 scrapes the heating plate 2, the impurities that fall off fall into the collection frame 10 and are collected. The mechanical vibration generated by the tapping of the energy storage plate 30 can drive the scraper plate 29 to shake, thereby preventing the scraped impurities from sticking to the surface of the scraper plate 29 as much as possible.

[0056] The side wall of the collection frame 10 is slidably connected to a support plate 19, and the top surface of the support plate 19 is fixedly connected to the bottom surface of the supporting frame 20. The support plate 19 realizes the fixed connection between the collection frame 10 and the supporting frame 20, thereby maintaining the synchronous movement of the absorption layer 8 and the scraping plate 29.

[0057] A mounting plate 16 is fixedly mounted on the side wall of the support frame 14 . A guide groove 17 is formed on the side wall of the mounting plate 16 , and one end of the guide groove 17 is raised.

[0058] The outer wall of the support plate 19 is elastically mounted with a sliding rod 35 which is slidably connected to the guide groove 17. When the scraper plate 29 slides toward the heating plate 2, the absorption layer 8 is affected by the sliding rod 35 and the guide groove 17 and slides downward until the absorption layer 8 is separated from the heating plate 2. In this way, during the sliding of the scraper plate 29, the absorption layer 8 is prevented from continuously contacting the heating plate 2 and generating friction, thereby protecting the absorption layer 8. After the scraping is completed, the scraper plate 29 is controlled to slide in the opposite direction until the absorption layer 8 is contacted with the heating plate 2 again.

[0059] The liquid supply mechanism includes a storage box 5 and a control pump 6. The storage box 5 is fixedly mounted on the inner wall of the mounting shell 1. The storage box 5 is used to store alcohol. The control pump 6 is fixedly mounted on the outer wall of the storage box 5. The control pump 6 is a common micro water pump.

[0060] The input end of the control pump 6 is connected to the inner cavity of the storage box 5, and the output end of the control pump 6 is connected to the inner cavity of the supporting frame 20. The alcohol inside the storage box 5 is extracted by the control pump 6 and finally discharged into the interior of the supporting frame 20 to achieve the wetting of the absorption layer 8.
