Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of bundling objects, in particular to a bundling device for logistics. BACKGROUND

[0002] In the modern logistics industry, automatic bundling machines have become an indispensable key equipment in the cargo packaging link due to their efficient and stable bundling performance. The working principle of the automatic bundling machine is to wrap the objects with a strap and use a heating plate to heat the strap so that it melts and adheres to each other, thereby achieving firm bundling.

[0003] The logistics industry is experiencing a peak period, and the cargo processing volume is growing explosively. The bundling machine needs to run continuously for a long time, which causes the heating plate to be in a working state continuously. In the process of repeatedly heating the strap, the plastic strap will produce some impurities due to heat melting and 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 bundling effect.

[0004] To ensure the bundling quality, the staff needs to clean the heating plate regularly. However, at present, when cleaning the heating plate, the operation of the bundling machine must be temporarily suspended, which interrupts the continuity of the logistics packaging and affects the overall work efficiency.

[0005] In addition, when facing stubborn dirt adhering to the surface of the heating plate, the operator usually increases the normal pressure between the scraper and the heating plate to enhance the cleaning effect. According to the principle of friction, as the normal pressure increases, the friction between the scraper and the heating plate will also continuously increase, which is easy to cause the plating layer on the surface of the heating plate to be scratched, shorten the service life, and further affect the heating performance and bundling quality.

DETAILED DESCRIPTION

[0046] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in conjunction with specific embodiments.

[0047] As shown in Figures 1 to 8 , the present application provides a bundling device for logistics, which comprises a bundling assembly, a heating mechanism, a power supply mechanism, a scraping mechanism, an immersion mechanism and a liquid supply mechanism.

[0048] The bundling assembly comprises an installation shell 1 and a material guide gantry 3, the material guide gantry 3 is fixedly installed at the upper end of the installation shell 1, when bundling the articles, the articles are placed below the material guide gantry 3, the bundling ribbon is adhered to the surface of the articles after passing through the material guide gantry 3 and is tightened, wherein the inside of the installation shell 1 is provided with a control module and a motor, the inside of the material guide gantry 3 is provided with a conveying roller group for conveying the bundling ribbon, the outside of the installation shell 1 is provided with a winding roller for winding the ribbon and a control panel, when in use, the articles are placed below the material guide gantry 3 until the ribbon is bound to the articles.

[0049] The heating mechanism comprises a heating plate 2 and a mounting cylinder 11, the mounting cylinder 11 is rotatably installed on the inner wall of the installation shell 1, the heating plate 2 is movably arranged on one side of the mounting cylinder 11, wherein the heating plate 2 uses the principle of resistance heating to heat the overlapping part of the bundling ribbon, so as to realize the hot melting fixation of the overlapping part.

[0050] The power supply mechanism is used to maintain the electrical connection between the power supply and the heating plate 2 after the heating plate 2 moves along the axis of the mounting cylinder 11;

[0051] At least two heating plates 2 are provided along the axis of the mounting cylinder 11. In this embodiment, two heating plates 2 are provided. One heating plate 2 is working and heating, while the other heating plate 2 is in preparation. With their cooperation, when plastic impurities are attached to the surface of the heating plate 2, the other can take over the work. When cleaning the heating plate 2 during the packaging production process, the machine can work without stopping and maintain smooth operation.

[0052] The scraping mechanism includes a scraper 29, a support plate 40, and an energy storage plate 30. The scraper 29 is made of elastic material and is fixedly installed on the outer wall of the support plate 40. The scraper 29 is used to scrape the surface of the heating plate 2 when there is dirt on the surface of the heating plate 2, so as to achieve a cleaning effect.

[0053] When dirt adheres to the surface of the heating plate 2 and affects the quality of hot melting, the contaminated heating plate 2 is controlled to retract into the interior of the mounting shell 1 by rotating the mounting cylinder 11, and the heating plate 2 located inside the mounting shell 1 moves to the heating position.

[0054] The support plate 40 is slidably disposed inside the mounting housing 1. The support plate 40 is slidably adjusted so that it slides in the horizontal direction. After the outer wall of the scraper plate 29 is in contact with the surface of the heating plate 2, the scraping of the heating plate 2 is realized.

[0055] The energy storage plate 30 is elastically set on the outer wall of the support plate 40. Pulling the energy storage plate 30 away from the support plate 40 releases the energy storage plate 30 when the scraper plate 29 scrapes the heating plate 2. The kinetic energy of the energy storage plate 30 hitting the support plate 40 is transferred to the scraper plate 29 to assist in scraping and cleaning the surface of the heating plate 2.

[0056] The kinetic energy generated by the impact of the energy storage plate 30 on the bearing plate 40 after being released will be transferred to the elastic scraper plate 29 through the bearing plate 40. This instantaneous impact, compared with uniform scraping, can generate high-frequency vibration or local stress concentration on stubborn dirt (such as sintered scale, hardened oil stains, etc.), making it easier for it to fall off the surface of the heating plate 2. At the same time, the scraper plate 29 itself is made of elastic material, and will undergo a brief deformation when it is impacted, which will instantly increase the contact pressure between it and the surface of the heating plate 2 and change the scraping angle. This dynamic change can cover gaps or dented areas that may be missed during uniform scraping, achieving a more comprehensive cleaning.

[0057] Traditional uniform-speed scraping often requires increasing the contact pressure between the scraper plate 29 and the heating plate 2 to remove stubborn dirt, which leads to increased wear on the scraper plate 29. However, the impact force of the energy storage plate 30 is intermittent, providing additional kinetic energy intermittently. It does not require continuous pressure on the scraper plate 29 towards the heating plate 2, thereby extending the service life of the scraper plate 29.

[0058] The immersion mechanism includes a support frame 20 and an absorbent layer 8 fixedly installed on the inner wall of the support frame 20. The absorbent layer 8 is made of common sponge. The liquid supply mechanism is used to wet the absorbent layer 8 (since the strap is usually made of PP or PET strap, the liquid used to wet the absorbent layer 8 is alcohol). Before the scraper 29 scrapes the heating plate 2, the wetted absorbent layer 8 is first controlled to adhere to the contaminated side of the heating plate 2. The plastic residue on the surface of the heating plate 2 is moistened and initially softened by alcohol. Then the scraper 29 scrapes the surface of the heating plate 2 to improve the cleaning quality.

[0059] In this embodiment, by wetting the surface of the heating plate 2 by the absorption layer 8, not only can the plastic residue on the surface of the heating plate 2 be softened, but the temperature of the surface of the heating plate 2 can also be reduced (the alcohol itself evaporates and absorbs heat). This prevents the surface temperature of the heating plate 2 from getting too high during scraping and cleaning, thus providing protection. Finally, the alcohol wetting reduces the coefficient of friction between the scraper 29 and the heating plate 2, reduces the friction during the scraping process, and reduces damage to the coating on the surface of the heating plate 2.

[0060] A control rod 26 is fixedly installed on the inner wall of the mounting cylinder 11. The control rod 26 is a common electric telescopic rod. A mounting block 27 is fixedly installed on the movable end of the control rod 26. The mounting block 27 is moved by extending or retracting the movable end of the control rod 26.

[0061] A hinge plate 21 is rotatably mounted on the side wall of the mounting block 27, and a mounting bracket 4 is fixedly mounted on the bottom surface of the heating plate 2. The other end of the hinge plate 21 is rotatably connected to the bottom surface of the mounting bracket 4. The number of hinge plates 21 is the same as the number of heating plates 2.

[0062] The outer wall of the mounting cylinder 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 that is slidably connected to the guide frame 9. Through the sliding cooperation between the guide frame 9 and the guide frame 22, the sliding trajectory of the mounting frame 4 is limited, thereby limiting the sliding trajectory of the heating plate 2.

[0063] An adjusting motor 25 is fixedly installed on the inner wall of the mounting housing 1. The adjusting motor 25 controls the rotation of the mounting cylinder 11 through a transmission component. A gear is fixedly installed on the output shaft of the adjusting motor 25. A gear ring that meshes with the gear is provided on the outer wall of the mounting cylinder 11. The rotating of the mounting cylinder 11 is controlled by the adjusting motor 25.

[0064] When the heating plate 2 needs to be cleaned, first retract the control lever 26 to control the sliding of the mounting block 27 until the heating plate 2 is completely retracted into the interior of the mounting housing 1. Then, adjust the motor 25 to drive the mounting cylinder 11 to rotate, control the two heating plates 2 to interchange positions, and finally control the control lever 26 to control the mounting block 27 to slide in the opposite direction, so that the upper heating plate 2 is in the working position.

[0065] In a preferred embodiment of the present invention, the power supply mechanism includes a support cylinder 7, a contact ring 13, a contact plate 23, a guide rod 24, and a terminal block 28.

[0066] The support cylinder 7 is fixedly installed on the inner wall of the mounting housing 1, and the electrical contact ring 13 is fixedly installed on the outer wall of the support cylinder 7 and electrically connected to the power supply. In this embodiment, the power supply is the power module built into the strapping machine, and the electrical contact ring 13 is made of wear-resistant graphite.

[0067] The terminal block 28 is fixedly installed on the outer wall of the mounting bracket 4 and electrically connected to the heating plate 2. The two can optionally be connected using enameled wire.

[0068] The contact plate 23 is connected to the terminal block 28 through an elastic element, and the outer wall of the contact plate 23 slides against the radial outer wall of the contact ring 13. The elastic element is a spring, and a connecting wire is provided between the terminal block 28 and the contact plate 23. The spring force pushes the contact plate 23 so that the contact plate 23 tends to adhere to the outer wall of the contact ring 13 in real time.

[0069] To prevent the contact plate 23 from misaligning, 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 misaligning.

[0070] The axis of the support cylinder 7 coincides with the axis of the mounting cylinder 11. During the rotation of the heating plate 2 and the mounting bracket 4, the contact plate 23 and the contact ring 13 remain in contact, thereby adapting to the power supply after the heating plate 2 rotates.

[0071] A support frame 14 is fixedly installed on the inner wall of the housing 1, and a drive screw 18 is fixedly installed on the outer wall of the support frame 14. The drive screw 18 is connected to the support frame 14 through a bearing.

[0072] A travel motor 12 is fixedly installed 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.

[0073] A threaded sleeve 34 is installed on the radial outer wall of the drive screw 18 through internal and external thread engagement. A guide bar 15 that is slidably connected to the threaded sleeve 34 is fixedly installed on the side wall of the support frame 14. The drive screw 18 is rotated by the travel motor 12, and the threaded sleeve 34 is rotated by the internal and external thread engagement. The guide bar 15 is provided to prevent the threaded sleeve 34 from rotating along the axis of the drive screw 18.

[0074] An elastic plate 33 is fixedly installed on the radial outer wall of the threaded sleeve 34. The other end of the elastic plate 33 is fixedly connected to the side wall of the bearing plate 40. The bearing plate 40 and the threaded sleeve 34 are connected by the elastic plate 33. When the traveling motor 12 controls the drive screw 18 to rotate, it drives the bearing plate 40 to slide, thereby controlling the scraper plate 29 to slide, so as to achieve the cleaning of the heating plate 2.

[0075] To improve the stability of the energy storage plate 30 during 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 support plate 40 and is slidably connected to the support plate 40. By setting the guide plate 39, the sliding trajectory of the energy storage plate 30 is limited, thereby improving the stability of the sliding of the energy storage plate 30.

[0076] A connecting rod 31 is fixedly installed 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 against the inner wall of the energy storage plate 30, thereby further improving the sliding stability of the energy storage plate 30.

[0077] 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. A rubber pad is provided on the side wall of the limiting hook plate 37 to increase 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 unidirectionally limited.

[0078] When the drive screw 18 rotates to control the threaded sleeve 34 and the bearing plate 40 to slide toward the wetted 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 bearing plate 40 slides, the elastic element between the bearing plate 40 and the energy storage plate 30 gradually stretches, storing elastic potential energy to prepare for the impact of the energy storage plate 30.

[0079] A pressing plate 38 for pressing the limiting hook plate 37 is fixedly installed on the outer wall of the connecting rod 31. As the distance between the bearing plate 40 and the energy storage plate 30 gradually increases, the pressing plate 38 gradually approaches the limiting hook plate 37 until the pressing plate 38 presses the limiting hook plate 37 and lifts the limiting hook plate 37. At this time, the limiting hook plate 37 is kept separated from the limiting tooth plate 32 due to the friction of the rubber pad. At this time, the energy storage plate 30 moves towards the bearing plate 40 and impacts it due to the elastic force.

[0080] A reset plate 36 is fixedly installed on the outer wall of the connecting rod 31. The limiting 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 moves the limiting hook plate 37 to rotate in the opposite direction until it engages with the limiting tooth plate 32 again.

[0081] To ensure smooth operation of the impact, the reset plate 36 is made of elastic material, and the guide plate 39 is provided with an elastic rubber pad on the side away from the energy storage plate 30. When impacted, the elastic rubber pad is compressed. During this process, the limit hook plate 37 moves the limit hook plate 37 to engage with the limit tooth plate 32.

[0082] In a preferred embodiment of the present invention, a collection frame 10 is fixedly installed on the outer wall of the support plate 40. 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, so as to prevent the scraped impurities from sticking to the surface of the scraper plate 29 as much as possible.

[0083] A support plate 19 is slidably connected to the side wall of the collection frame 10. The top surface of the support plate 19 is fixedly connected to the bottom surface of the carrier frame 20. The support plate 19 achieves a fixed connection between the collection frame 10 and the carrier frame 20, thereby maintaining the synchronous movement of the absorption layer 8 and the scraping plate 29.

[0084] A mounting plate 16 is fixedly installed on the side wall of the support frame 14. A guide groove 17 is provided on the side wall of the mounting plate 16, and one end of the guide groove 17 is raised.

[0085] The outer wall of the support plate 19 is elastically fitted with a slide rod 35 that is slidably connected to the guide groove 17. As the scraper plate 29 slides toward the heating plate 2, the absorption layer 8 is affected by the slide rod 35 and the guide groove 17 and slides downward until the absorption layer 8 separates from the heating plate 2. This prevents the absorption layer 8 from continuously sticking to the heating plate 2 and generating friction during the sliding of the scraper plate 29, thus protecting the absorption layer 8. After the scraping is finished, the scraper plate 29 is controlled to slide in the opposite direction until the absorption layer 8 sticks to the heating plate 2 again.

[0086] The liquid supply mechanism includes a storage tank 5 and a control pump 6. The storage tank 5 is fixedly installed on the inner wall of the mounting housing 1 and is used to store alcohol. The control pump 6 is fixedly installed on the outer wall of the storage tank 5 and is a common miniature water pump.

[0087] The input end of the control pump 6 is connected to the inner cavity of the storage tank 5, and the output end of the control pump 6 is connected to the inner cavity of the support frame 20. The control pump 6 draws out the alcohol inside the storage tank 5 and finally discharges it into the interior of the support frame 20 to achieve the wetting of the absorption layer 8.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
