Description

Technical Field

[0001] The utility model relates to the technical field of glue pumps, in particular to a glue pump for a corrugated cardboard gluing device. Background Technique

[0002] A corrugated cardboard gluing device is a device used to evenly apply glue on the surface of corrugated cardboard. Its design and function are crucial for improving the processing quality and efficiency of corrugated cardboard. In the gluing device, a glue pump is needed to transport the glue from the glue storage tank into the glue outlet roller of the gluing device;

[0003] Defect: The sealing performance of the connection position between the existing glue pump and the pipeline is poor. After long-term use, the glue will leak out from the connection position between the glue pump and the pipeline, resulting in damage to the equipment;

[0004] To solve the above defects, the prior art (Chinese patent with application number: 201821751330.4, application date: October 28, 2018) discloses a leak-proof transfer pump for transporting high-temperature solid-liquid mixtures. The lower end of the first disc of the flange is welded with an annular clamping block, and the second disc is clamped and connected with the annular clamping block through a second annular groove. By increasing the path through which the solid-liquid mixture passes, the solid-liquid mixture is not easily leaked out from the gap between the first disc and the second disc, achieving the leak-proof effect. Then, a first annular groove is opened on the second disc, and a sealing rubber strip is abutted against the inner wall of the first annular groove. The sealing rubber strip is a rubber-produced rubber strip for product sealing, which can prevent the leakage or intrusion of internal and external media, and can prevent or reduce the damage caused by mechanical vibration and impact, thereby achieving functions such as sound insulation, heat insulation, and shock absorption of an elastic strip or rod-shaped material, also achieving the leak-proof effect;

[0005] The prior art makes the solid-liquid mixture not easily leaked out from the gap between the first disc and the second disc by clamping and connecting the second annular groove on the flange with the annular clamping block, achieving the leak-proof effect. However, only through snap-in sealing, the sealing performance is poor, and the outside of the connection position between the two flanges cannot be sealed, resulting in the glue still leaking out from the gap between the two flanges during the transportation process, and then the sealing performance of the glue pump is poor.

[0006] Therefore, we propose a glue pump for a corrugated cardboard gluing device that can well solve the above problems. Content of the Utility Model

[0007] The purpose of the utility model is to provide a glue pump for a corrugated cardboard gluing device to solve the problem that the outside of the connection position between the two flanges cannot be sealed, resulting in the glue still leaking out from the gap between the two flanges during the transportation process, and then the sealing performance of the glue pump is poor proposed in the above background technique.

[0008] To achieve the above object, the utility model provides the following technical solution: a gluing pump for a corrugated board gluing device, comprising a bottom plate, a motor is installed on the left bolt on the upper surface of the bottom plate, and a transmission rod is fixedly connected to the output end of the motor, a pump body is connected to the right bolt on the upper surface of the bottom plate, and one end of the transmission rod away from the motor is fixedly connected to the rotor inside the pump body;

[0009] The pump body is also provided with an input pipe and an output pipe bolted to the front and rear ends of the pump body through flanges, and the front and rear ends of the pump body are fixedly connected with sealing sleeves, the interior of the sealing sleeve is connected with a driven gear through a shaft at an equal angle, and the interior of the sealing sleeve is provided with cavities at an equal angle;

[0010] A threaded rod is connected to the interior of the sealing sleeve above the driven gear, and one end of the threaded rod is connected to the shaft end of the driven gear through a bevel gear set, and a piston plate is sleeved on the outer side of one end of the threaded rod;

[0011] A sealing airbag is embedded in the inner side of the sealing sleeve, and a connecting pipe is fixedly connected between the sealing airbag and the cavity. Racks are fixedly connected to the side surfaces of the flanges on the input pipe and the output pipe.

[0012] Preferably, the sealing airbag is connected to the interior of the cavity via a connecting pipe, the outer side of the piston plate is in sealing sliding connection with the inner wall of the cavity, and the piston plate is in threaded connection with the threaded rod.

[0013] Preferably, the threaded rod is rotatably connected to the inside of the sealing sleeve, and the rack and the driven gear are meshingly connected.

[0014] Preferably, one end of the threaded rod extends into the interior of the cavity, and one end of the threaded rod is connected to an inner wall bearing of the cavity.

[0015] Preferably, a movable block is fixedly connected to the outer side of the transmission rod, a movable plate is hinged on the upper surface of the bottom plate, a fitting block is fixedly connected to the left side of the top of the movable plate, and a striking block is fixedly connected to the right side of the top of the movable plate.

[0016] Preferably, the positions of the movable block and the fitting block correspond, and the ends of the movable block and the fitting block fit together.

[0017] Preferably, the two striking blocks are respectively arranged below the input pipe and the output pipe, and a vortex spring is installed at the connection position between the shaft end in the middle of the movable plate and the bottom plate.

[0018] Compared with the prior art, the utility model has the following beneficial effects: the gluing pump of the corrugated board gluing device adopts a new structural design, the specific contents of which are as follows:

[0019] (1) One end of the input pipe is connected to the glue storage tank on the glue application device, and the other end is sealed and connected to the input end of the pump body through a flange. At the same time, one end of the output pipe is connected to the glue outlet roller on the glue application device, and the other end is sealed and connected to the output end of the pump body through a flange. Then, when the flanges on the input pipe and the output pipe are inserted into the sealing sleeve, the rack on the side can drive the driven gear to rotate. At this time, the driven gear drives the threaded rod to rotate by the bevel gear set, so that the piston plate moves inside the cavity and pushes the gas into the sealing airbag through the exhaust pipe, so that the sealing airbag expands and squeezes and seals between the two flanges, thereby improving the sealing of the connection between the pump body and the input pipe and the output pipe, and preventing the rubber from leaking during the transportation process;

[0020] Furthermore, when the input pipe and the output pipe are separated from the pump body, the rack drives the driven gear to rotate in the opposite direction, and the threaded rod drives the piston plate to reset in the cavity, so that the gas in the sealing airbag is sucked into the cavity through the connecting pipe. At this time, the sealing airbag shrinks and no longer seals the connection position between the pump body and the input pipe and the output pipe;

[0021] (2) When the motor drives the pump body to work through the transmission rod, the transmission rod drives the movable block to move to the bonding block position and squeezes the bonding block to move it downward. At the same time, due to the lever principle, the striking block at the other end of the movable plate moves upward and strikes the input pipe and the output pipe, which can generate a certain vibration, thereby preventing the rubber inside the input pipe and the output pipe from being blocked and affecting the subsequent glue supply work;

[0022] Furthermore, when the movable block moves away from the fitting block, the movable plate rotates and resets under the stored force of the vortex spring, and drives the striking block to reset, and repeats the above operation, so that the striking block can reciprocately strike the input pipe and the output pipe.

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Please refer to Figures 1-7 , the present utility model provides the following technical solutions: a glue pump for a corrugated cardboard gluing device;

[0033] Embodiment 1: In order to solve the problem that in the prior art, the outside of the connection position of the two flanges 11 cannot be sealed, resulting in the leakage of the glue material from the gap between the two flanges 11 during the conveying process, and then the poor sealing performance of the glue pump, the following solution is thus disclosed. Specifically refer to Figures 1-5 and Figure 7As shown, it includes a base plate 1, and the front and rear ends of the pump body 3 are respectively bolted with an input pipe 5 and an output pipe 6 through a flange 11, and the front and rear ends of the pump body 3 are fixedly connected with a sealing sleeve 7, and the interior of the sealing sleeve 7 is equiangularly connected to a driven gear 9 through an axis rotation, and a cavity 12 is opened at an equiangular angle inside the sealing sleeve 7; a threaded rod 15 is connected to the upper part of the driven gear 9 inside the sealing sleeve 7, and one end of the threaded rod 15 is connected to the shaft end of the driven gear 9 through a bevel gear set, and a piston plate 14 is sleeved on the outer side of one end of the threaded rod 15, and one end of the threaded rod 15 extends into the interior of the cavity 12, and the threaded rod 15 is connected to the driven gear 9 through a bevel gear set. One end of the threaded rod 15 is connected to the inner wall bearing of the cavity 12; a sealing airbag 8 is embedded in the inner side of the sealing sleeve 7, and a connecting pipe 16 is fixedly connected between the sealing airbag 8 and the cavity 12, and the sealing airbag 8 is communicated with the inside of the cavity 12 through the connecting pipe 16. The outer side of the piston plate 14 and the inside of the cavity 12 are sealed and slidably connected, and the piston plate 14 and the threaded rod 15 are threadedly connected. The side surfaces of the flange 11 on the input pipe 5 and the output pipe 6 are fixedly connected with a rack 10, and the threaded rod 15 is rotatably connected to the inside of the sealing sleeve 7, and the rack 10 and the driven gear 9 are meshingly connected;

[0034] When in use, one end of the input pipe 5 is connected to the glue storage tank on the glue application device, and the other end is sealed with the input end of the pump body 3 through the flange 11. At the same time, one end of the output pipe 6 is connected to the glue output roller on the glue application device, and the other end is sealed with the output end of the pump body 3 through the flange 11. Then, when the flanges 11 on the input pipe 5 and the output pipe 6 are inserted into the sealing sleeve 7, the rack 10 on the side thereof can drive the driven gear 9 to rotate. At this time, the driven gear 9 drives the threaded rod 15 to rotate by the bevel gear set, so that the piston plate 14 moves inside the cavity 12 and pushes the gas through the connecting pipe 16. The gear 10 is inserted into the sealing airbag 8, so that the sealing airbag 8 expands and squeezes and seals the two flanges 11, thereby improving the sealing of the connection between the pump body 3 and the input pipe 5 and the output pipe 6 to prevent the glue from leaking during transportation. Then, when the input pipe 5 and the output pipe 6 are separated from the pump body 3, the rack 10 drives the driven gear 9 to rotate in the opposite direction, and the threaded rod 15 drives the piston plate 14 to reset in the cavity 12, and the gas in the sealing airbag 8 is sucked into the cavity 12 through the connecting pipe 16. At this time, the sealing airbag 8 shrinks and no longer squeezes and seals the connection between the pump body 3 and the input pipe 5 and the output pipe 6.

[0035] Embodiment 2: Different from Embodiment 1, this embodiment can drive the pump body 3 to work through the motor 2 and the transmission rod 4. Figure 1 and Figure 2As shown, the left bolt on the upper surface of the bottom plate 1 is equipped with a motor 2, and the output end of the motor 2 is fixedly connected to a transmission rod 4, the right bolt on the upper surface of the bottom plate 1 is connected to a pump body 3, and the end of the transmission rod 4 away from the motor 2 is fixedly connected to the rotor inside the pump body 3;

[0036] Start the motor 2, which drives the rotor inside the pump body 3 to rotate rapidly through the transmission rod 4. Since the rotor is the internal medium, there is no direct contact between them and the conveyed glue liquid, and the glue liquid will not be contaminated. At this time, the rotation will generate negative pressure, and the glue material will be sucked and sealed through the input end and the input pipe 5, and then gradually moved to the output end position in the pump body 3, and the glue material is pushed into the output pipe 6 and into the glue outlet roller on the glue application device, and then the glue material is sucked from the feed port again to form a continuous conveying operation.

[0037] Embodiment 3: Different from Embodiment 2, this embodiment uses the striking block 20 to strike the input pipe 5 and the output pipe 6 back and forth, thereby preventing the rubber inside the input pipe 5 and the output pipe 6 from being blocked and affecting the subsequent glue supply. For details, refer to Figure 1 and Figure 6 As shown, a movable block 19 is fixedly connected to the outer side of the transmission rod 4, a movable plate 17 is hinged on the upper surface of the bottom plate 1, and a fitting block 18 is fixedly connected to the left side of the top of the movable plate 17, the positions of the movable block 19 and the fitting block 18 correspond, and the movable block 19 fits with the end of the fitting block 18, and a striking block 20 is fixedly connected to the right side of the top of the movable plate 17, and the two striking blocks 20 are respectively arranged below the input pipe 5 and the output pipe 6, and a vortex spring 13 is installed at the connection position between the shaft end in the middle of the movable plate 17 and the bottom plate 1;

[0038] When the motor 2 drives the pump body 3 to work through the transmission rod 4, the transmission rod 4 drives the movable block 19 to move to the position of the fitting block 18, and squeezes the fitting block 18 to cause it to move downward. At the same time, due to the lever principle, the striking block 20 at the other end of the movable plate 17 moves upward and strikes the input pipe 5 and the output pipe 6. When the movable block 19 is away from the fitting block 18, the movable plate 17 rotates and resets under the accumulated force of the vortex spring 13, and drives the striking block 20 to reset. The above operation is repeated, so that the striking block 20 can reciprocate and strike the input pipe 5 and the output pipe 6, which can generate a certain vibration, thereby preventing the rubber inside the input pipe 5 and the output pipe 6 from being blocked and affecting the subsequent rubber supply work.

[0039] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0040] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
