Description

Technical Field

[0001] This application relates to filtration equipment, and more particularly to a multi-channel glue recovery device. Background Technology

[0002] Currently, in the paper box manufacturing industry, gluing and forming processes play a crucial role in the final quality of the paper boxes. The gluing process involves applying hot melt adhesive or water-based adhesive to the creases and joints of the paper box, and then applying pressure to bond the components together, thus achieving the connection.

[0003] When using water-based adhesives, companies generally adopt an over-application strategy to cope with uncertainties such as differences in paper absorbency and fluctuations in environmental humidity. At the same time, due to the long curing cycle of adhesives, an adhesive recycling process is usually added between the adhesive application process and the carton forming process.

[0004] However, when recycling the remaining glue, a large amount of paper scraps generated during the cutting and folding process in the cardboard box production environment will enter the recycling system along with the glue.

[0005] The filter in the recycling system is a key component for separating glue from impurities, but the presence of paper scraps easily causes filter clogging. Once the filter is clogged, glue recycling efficiency drops significantly, glue supply is delayed, and this affects the overall production schedule of the cardboard boxes, leading to a significant reduction in production efficiency. In addition, frequent cleaning of clogged filters not only increases labor maintenance costs but also causes production interruptions due to equipment downtime, further exacerbating production losses.

[0006] Therefore, a technical solution is needed to reduce the impact of filter clogging on the efficiency of cardboard box production. Utility Model Content

[0007] The technical problem this application aims to solve is: how to reduce the impact of filter clogging on the efficiency of cardboard box production.

[0008] To address the aforementioned technical problems, this application provides a multi-channel adhesive recycling device, comprising:

[0009] Hollow slider, with a glue inlet tube coaxially connected to the upper end of the hollow slider;

[0010] The slide rail has a first dispensing tube and a second dispensing tube fixedly connected to its lower end, and a filter screen is installed in either the first dispensing tube or the second dispensing tube.

[0011] The hollow slider is slidably connected to the slide rail, so that the hollow slider is connected to the first or second glue outlet tube, and the glue from the glue inlet tube flows into the first or second glue outlet tube through the hollow slider.

[0012] In one embodiment, the upper end of the slide rail is provided with two indicator marks, which are aligned with the first dispensing tube and the second dispensing tube, respectively.

[0013] In one embodiment, the slide rail is provided with a slide groove, and the side of the slide groove is provided with two sets of spherical grooves. The side of the hollow slider is provided with a set of ball bearings. When the hollow slider slides in the slide groove, the ball bearings cooperate with one of the sets of spherical grooves.

[0014] In one embodiment, the groove is a dovetail groove, and the hollow slider is a dovetail-shaped slider that matches the dovetail groove.

[0015] In one embodiment, the multi-channel glue recycling device further includes a first sliding cover and a second sliding cover. The first sliding cover and the second sliding cover are slidably connected to a slide rail. The first sliding cover is connected to the side of the hollow slider near the first glue outlet tube, and the second sliding cover is connected to the side of the hollow slider near the second glue outlet tube. The bottom width and bottom length of the first sliding cover or the second sliding cover are both greater than the inner diameter of the first glue outlet tube or the second glue outlet tube.

[0016] In one embodiment, the first sliding cover or the second sliding cover is detachably connected to the hollow slider.

[0017] In one embodiment, the first sliding cover or the second sliding cover is detachably connected to the hollow slider by a hand-tightening nut.

[0018] In one embodiment, a rigid metal rod is installed in either the first or second dispensing tube. A first pin and a second pin are fixed to the sidewalls of the first and second dispensing tubes. The filter screen is made of metal and is connected to the first pin. The metal rod is connected to the second pin. A power supply and an alarm device are connected in series between the first and second pins.

[0019] In one embodiment, the multi-channel glue recovery device is further provided with an electric push rod or a cylinder, which is connected to the side of the glue inlet pipe.

[0020] In one embodiment, the bottom surface of the hollow slider is provided with a wear-resistant coating.

[0021] Compared with the prior art, the multi-channel glue recycling device of this application has the following advantages:

[0022] By setting up two glue outlet pipes, the first and second, and combining the sliding cooperation between the hollow slider and the slide rail, when a blockage occurs, the glue inlet pipe can be pushed to connect with either glue outlet pipe to achieve seamless switching. The dual pipes and dual filters extend the service life and reduce the impact of filter blockage on paper box production efficiency. Attached Figure Description

Detailed Implementation

[0032] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0033] In the description of this application, it should be understood that the terms "first," "second," etc., in the specification, claims, and accompanying drawings are intended to distinguish similar objects and are not used to describe a specific structure. It should be understood that such terms are interchangeable where appropriate so that embodiments of this application can be implemented in structures other than those illustrated or described. Furthermore, "comprising," "having," and any variations thereof are intended to cover non-exclusive inclusion. For example, a product or device comprising a series of components or units is not necessarily limited to those explicitly listed, but may also include other components or units not explicitly listed but inherent to these products or devices.

[0034] In today's cardboard box manufacturing industry, cardboard box forming equipment commonly uses glue as an adhesive material to ensure a stable connection between the various components of the cardboard box. This practice does indeed meet the basic quality requirements of cardboard boxes in actual production.

[0035] As production continues, operators often use excessive amounts of glue to ensure good adhesion of the cardboard boxes. This results in a large amount of leftover glue generated during production. Considering factors such as cost and environmental protection, recycling and reusing this leftover glue is particularly important.

[0036] However, the production environment for cardboard boxes is quite unique. During production, processes such as cutting and folding generate a large amount of paper scraps. When residual glue is recycled, these paper scraps inevitably end up in the recycling system along with the glue.

[0037] In the entire glue recycling system, the filter plays a crucial role, undertaking the key task of separating glue from impurities. However, in reality, the presence of paper scraps causes significant problems for the filter. Due to the shape and characteristics of paper scraps, they easily clog the filter.

[0038] If the filter becomes clogged, the entire production process will be severely affected. Glue recycling efficiency will drop significantly, directly causing delays in glue supply. Without glue, cardboard box production cannot proceed smoothly, hindering the overall production schedule and significantly reducing production efficiency.

[0039] Furthermore, once the filter becomes clogged, it requires frequent cleaning to restore its normal operation. This not only increases labor maintenance costs, but also necessitates equipment shutdown during filter cleaning, causing production interruptions. Each production interruption results in additional production losses, further increasing production costs.

[0040] This shows that the problem of clogged glue recycling filters in the current paper box production process has seriously affected production efficiency and cost control.

[0041] Based on this, such as Figure 1 As shown, this application provides a multi-channel glue recycling device 1, which may include a hollow slider 11 and a slide rail 12.

[0042] The upper end of the hollow slider 11 is coaxially connected to the glue inlet pipe 111, and the lower end of the slide rail 12 is fixedly connected to the first glue outlet pipe 121 and the second glue outlet pipe 122. A filter screen 1211 is installed in either the first glue outlet pipe 121 or the second glue outlet pipe 122.

[0043] The hollow slider 11 is slidably connected to the slide rail 12, so that the hollow slider 11 is connected to the first glue outlet tube 121 or the second glue outlet tube 122, so that the glue from the glue inlet tube 111 flows into the first glue outlet tube 121 or the second glue outlet tube 122 through the hollow slider 11.

[0044] The design employs a dual-pipeline, dual-filter 1211 system. When the filter 1211 in one pipeline becomes clogged, the glue can flow into the other pipeline by sliding the hollow slider 11. This reduces the chance of glue supply interruption due to filter 1211 clogging and effectively improves overall production efficiency.

[0045] Meanwhile, traditional single-filter 1211 designs are prone to clogging, requiring frequent cleaning of the filter 1211, which significantly increases manual maintenance costs. However, the dual-pipeline, dual-filter 1211 design in this application uses two filters alternately, extending the overall lifespan of the filters 1211. For example, a single-filter 1211 might need cleaning every 2 hours of operation, but with the dual-filter 1211 design, the two filters 1211 are used alternately, requiring cleaning of the clogged filter 1211 only every 4-6 hours. This reduced cleaning frequency directly decreases the time and effort spent manually cleaning the filters 1211, lowering manual maintenance costs.

[0046] Based on this, in one embodiment, such as Figure 2 and Figure 3 As shown, two indicator marks 123 can be provided at the upper end of the slide rail 12, and the two indicator marks 123 are respectively aligned with the first dispensing tube 121 and the second dispensing tube 122.

[0047] When operating the equipment, operators can intuitively understand which dispensing tube the hollow slider 11 is aligned with through the indicator marks 123, i.e., which filter 1211 is being used for glue recycling. This reduces the difficulty of operation, decreases reliance on skilled workers, and lowers labor costs.

[0048] Furthermore, in another embodiment of this application, such as Figure 2 , Figure 3 and Figure 4 As shown, the slide rail 12 is provided with a slide groove 124, and the side of the slide groove 124 is provided with two sets of spherical grooves 125. The side of the hollow slider 11 is provided with a set of ball bearings 112. When the hollow slider 11 slides in the slide groove 124, the ball bearings 112 cooperate with one of the sets of spherical grooves 125.

[0049] A door catch is a small hardware accessory used on movable parts such as doors and drawers, mainly for positioning and limiting.

[0050] A ball catch typically consists of two parts: a ball holder mounted on a fixed object, containing a spring and a steel ball; and a catch block mounted on a moving part. When the moving part is closed, the catch block compresses the steel ball, causing the spring to compress. When the moving part reaches the desired position, the steel ball, under the force of the spring, engages in the groove of the catch block, thus achieving positioning and maintaining the closed state. When it is necessary to open the moving part, a certain external force must be applied to overcome the spring force, causing the steel ball to disengage from the groove of the catch block.

[0051] In this application, the ball bearing 112 contains a spring, and the slide rail 12 slides relative to the hollow slider 11. Therefore, the slide rail 12 can serve as a moving part in this application. When the hollow slider 11 slides to a specific position, the ball bearing 112, under the action of the spring force, engages in the spherical groove 125. The spherical design of the spherical groove 125 is adapted to the shape of the ball bearing 112, which can effectively limit the displacement of the slider perpendicular to the sliding direction, thereby achieving the positioning of the slider on the slide rail. When it is necessary to move the slider again, a certain external force is applied to overcome the spring force, the ball bearing 112 disengages from the spherical groove 125, and the slider can continue to slide to another position of the spherical groove 125, achieving positioning again.

[0052] The indicator mark 123 can indicate the position, while the elastic ball 112 and the spherical groove 125 can directly limit the position of the hollow slider 11. When the hollow slider 11 slides in the groove 124, the ball 112 and the spherical groove 125 cooperate to achieve precise positioning of the hollow slider 11, ensuring that the hollow slider 11 can accurately connect with the first glue outlet tube 121 or the second glue outlet tube 122, so that the glue can flow smoothly into the corresponding pipe and filter screen 1211.

[0053] The engagement of the ball 112 and the spherical groove 125 is equivalent to a mechanical locking mechanism. The hollow slider 11 will only slide when a certain external force is applied to disengage the ball 112 from the spherical groove 125, thus reducing the probability of misoperation.

[0054] Based on this, the slide groove 124 can be a dovetail groove, and the hollow slider 11 is a dovetail-shaped slider that matches the dovetail groove.

[0055] Compared to ordinary sliders, the combination of dovetail grooves and dovetail-shaped sliders can restrict both horizontal and vertical displacement. This makes it difficult for the dovetail-shaped slider to detach from the dovetail groove even under significant external impact or vibration during the operation of the multi-channel glue recycling device 1. This ensures the stable operation of the hollow slider 11 on the slide rail 12.

[0056] In terms of precision, this tightly fitted structure enables more accurate positioning. Combined with the positioning mechanism of the ball bearing 112 and the spherical groove 125 mentioned earlier, the dovetail groove and dovetail slider further ensure that the hollow slider 11 is accurately connected to the first glue outlet tube 121 or the second glue outlet tube 122, making the working precision of the multi-channel glue recycling device 1 higher, effectively avoiding problems such as poor glue recycling caused by positioning deviation, and improving the efficiency and quality of glue recycling.

[0057] like Figure 7 As shown, when the hollow slider 11 is connected to the second dispensing tube 122, the first dispensing tube 121 is open. If the amount of glue dispensed is too large, it is easy to overflow from the top of the first dispensing tube 121.

[0058] To reduce the possibility of spillage, in one embodiment of this application, the multi-channel glue recycling device 1 may further include a first sliding cover 13 and a second sliding cover 14. The first sliding cover 13 and the second sliding cover 14 are slidably connected to the slide rail 12, respectively. The first sliding cover 13 is connected to the side of the hollow slider 11 near the first glue outlet tube 121, and the second sliding cover 14 is connected to the side of the hollow slider 11 near the second glue outlet tube 122. The bottom width and bottom length of the first sliding cover 13 or the second sliding cover 14 are both greater than the inner diameter of the first glue outlet tube 121 or the second glue outlet tube 122.

[0059] Since the bottom width and bottom length of the first sliding cover 13 or the second sliding cover 14 are both greater than the inner diameter of the first dispensing tube 121 or the second dispensing tube 122, the sliding cover can always cover the dispensing tube opening when it moves with the hollow slider 11.

[0060] like Figure 6 As shown, when the hollow slider 11 moves to the second dispensing tube 122, the first dispensing tube 121 is no longer open but is blocked by the first sliding cover 13. This prevents excess glue from overflowing from the top of the first dispensing tube 121 when the dispensing volume is large. Similarly, when the hollow slider 11 moves to the first dispensing tube 121, the second dispensing tube 122 is blocked by the second sliding cover 14. This also prevents excess glue from overflowing from the top of the second dispensing tube 122 when the dispensing volume is large.

[0061] Based on this, in one embodiment of this application, the first sliding cover 13 or the second sliding cover 14 is detachably connected to the hollow slider 11.

[0062] With a detachable connection, when the second dispensing tube 122 is involved in dispensing filtered adhesive, the first sliding cover 13 can be removed to take out the filter screen 1211 in the first dispensing tube 121 for cleaning. Similarly, when the first dispensing tube 121 is involved in dispensing filtered adhesive, the filter screen 1211 in the second dispensing tube 122 can be cleaned. This allows for cleaning without stopping the machine, reducing downtime and improving overall production efficiency.

[0063] In another embodiment, the first sliding cover 13 or the second sliding cover 14 is detachably connected to the hollow slider 11 by a hand-tightening nut.

[0064] The hand-tightening nut design allows for the removal and installation of the sliding cover without the need for additional tools. When cleaning the filter 1211, the operator can quickly unscrew the nut with just their hands, detach the sliding cover from the hollow slider 11, and then remove the filter 1211 for cleaning.

[0065] Hand-tightening nuts greatly saves operation time, reduces equipment downtime, and ensures efficient and continuous paper box production.

[0066] like Figure 5 As shown, a rigid metal rod 15 is installed in either the first dispensing tube 121 or the second dispensing tube 122. A first pin 16 and a second pin 17 are fixed to the side wall of either the first dispensing tube 121 or the second dispensing tube 122. The filter screen 1211 is made of metal. The filter screen 1211 is connected to the first pin 16, and the metal rod is connected to the second pin 17. A power supply and an alarm device are connected in series between the first pin 16 and the second pin 17.

[0067] Through the above scheme, the rigid metal rod 15 is difficult to deform under the impact of the glue, while the metal filter screen 1211 gradually deforms downward as blockage occurs. When the deformation is sufficient to bring the filter screen 1211 into contact with the rigid metal rod 15, the two become conductive, thus connecting the first pin 16 and the second pin 17. At this time, the first pin 16, the filter screen 1211, the rigid metal rod 15, and the second pin 17 constitute a switch. When the blockage is severe, the switch closes.

[0068] Therefore, when a power supply and an alarm device are connected in series between the first pin 16 and the second pin 17, the alarm device can be powered by the power supply when the switch is closed (i.e., when a blockage occurs).

[0069] It is understood that the alarm device can be any existing type, such as sound type (speaker, buzzer), light type (light bulb, light-emitting diode), or signal type (wireless transmitter, wired transmitter). The examples are merely illustrative and are not intended to limit the scope of protection of this application. Those skilled in the art can also select other types of alarm devices based on the teachings of this application. The solutions obtained by adaptive modifications based on the solutions of this application should fall within the scope of protection of this application.

[0070] In addition, the multi-channel glue recycling device 1 of this application is also provided with an electric push rod or a cylinder, which is connected to the side of the glue inlet pipe 111.

[0071] The accuracy of aligning and connecting the glue inlet tube 111 with the first glue outlet tube 121 or the second glue outlet tube 122 can be improved by using an electric actuator or a cylinder, and the need for manual labor can be reduced.

[0072] Furthermore, the bottom surface of the hollow slider 11 can be provided with a wear-resistant coating. With increased use, if the bottom surface of the hollow slider 11 wears down, the slider's sliding on the slide rail 12 will no longer be smooth, and the positioning accuracy will be affected. The wear-resistant coating can slow down this wear and improve the durability of the multi-channel glue recycling device 1.

[0073] Optionally, the wear-resistant coating can be a ceramic coating, a tungsten carbide coating, a thermally sprayed metal wear-resistant coating (such as a nickel-based alloy coating), or a polytetrafluoroethylene coating.

[0074] The multi-channel glue recycling device 1 provided in this application embodiment allows glue to flow into the hollow slider 11 through the glue inlet pipe 111 during operation. The first or second glue outlet pipe 122 and its filter screen 1211 are then selected by moving the hollow slider 11. During the process, the sliding cover provides protection and sealing. The filter screen 1211 can be easily cleaned by disassembling the sliding cover. The wear-resistant coating on the bottom surface of the hollow slider 11 ensures long-term stable operation. This device solves the problem of easy clogging of the filter screen 1211, improves glue recycling and production efficiency, reduces maintenance costs, and improves the quality of paper box production.

[0075] The above are merely preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
