Description

Technical Field

[0001] This utility model relates to the technical field of glue collection mechanisms, and more specifically to a glue collection mechanism for an offset printing paper gluing machine. Background Technology

[0002] Offset printing paper sizing machines are used to sizing offset printing paper. For example, a double-roller trough sizing press device: the paper enters a trough filled with sizing liquid, formed by two rollers. As the paper passes through the trough, the sizing liquid adheres to the paper surface, achieving sizing. A gate roller sizing press device: the middle two rollers are called the top rollers, the outer rollers are the metering rollers, and the outermost roller is called the bottom roller. A sizing liquid trough is formed between the metering rollers and the bottom roller, creating a sizing film on the roller surface. The top rollers transfer this film to the paper surface, forming a sizing film and achieving surface sizing. During the sizing process, to prevent over-sizing, the sizing machine is equipped with rollers to squeeze out excess sizing liquid from the printing paper, and a sizing collection mechanism is also included to recover excess sizing liquid.

[0003] For example, the glue collection mechanism of the offset printing paper gluing machine with prior art disclosure number CN221118100U collects glue liquid through a closed glue collection device, which can keep the glue box away from the roller, prevent dust from entering and contaminating the glue liquid, improve the quality of the recycled glue liquid, and protect the paper and glue liquid from cross-contamination in case of failure, leaving enough space for the paper to pile up and prevent the paper from tearing.

[0004] However, the existing technology described above still has the following problems in use: although the small opening of the glue collector can prevent dust, fiber debris from the printing paper can still easily mix into the glue solution. This fiber debris affects the flow rate of the glue solution, causing it to overflow from the glue collector. If the fiber debris accumulates inside the glue tank for a long time, it will increase the subsequent filtration cost and is difficult to clean. Therefore, this utility model provides a glue collection mechanism for an offset printing paper gluing machine with anti-clogging and filtration functions. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a glue collection mechanism for an offset printing paper gluing machine. It collects excess glue from the paper via an inlet hopper and a guide hopper. Simultaneously, two spiral augers rotate synchronously, generating thrust that propels the glue downwards rapidly. This accelerates the glue flow rate, preventing overflow from the inlet hopper, and also agitates the glue at the filter screen, preventing impurities from clogging the screen and thus improving the filtration rate. This addresses the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a glue collection mechanism for an offset printing paper gluing machine, comprising a glue collection box, wherein liquid inlet hoppers are connected to both sides of the top of the glue collection box, and anti-clogging components are provided inside the two liquid inlet hoppers, wherein the anti-clogging components include spiral augers, the two spiral augers are installed inside the glue collection box by bearings, and the two spiral augers are connected by a connecting component, wherein the top and bottom walls of the glue collection box are both set as inclined surfaces sloping towards the center, and two symmetrically distributed frame plates are fixedly provided inside the glue collection box, and the two frame plates are both located between the two spiral augers, and a filter screen is fixedly provided inside the frame plates.

[0007] In a preferred embodiment, a guide bucket is fixedly provided between the two liquid inlet buckets, and the guide bucket is connected to the interior of the two liquid inlet buckets. The guide bucket has a through hole inside. The guide bucket can collect excess glue to prevent glue from dripping onto the glue collection box.

[0008] In a preferred embodiment, the connecting assembly includes a waterproof motor with a sealing cover fitted on its outer wall. The sealing cover is fixed inside the liquid inlet hopper. The bottom end of the output shaft of the waterproof motor is fixed to the top end of one of the spiral augers. The two spiral augers are connected by a belt drive. The belt drive is located inside the through hole. The waterproof motor and the belt drive are used to drive the two spiral augers to rotate synchronously, thereby preventing blockage.

[0009] In a preferred embodiment, a drain pipe extends through the center of the bottom of the glue collecting box, and the drain pipe communicates with the interior of the glue collecting box. A sealing plug is provided inside the drain pipe, and a vertical rod is fixedly provided at the bottom of the sealing plug. A threaded cap is movably connected to the bottom of the vertical rod, and the threaded cap is threadedly connected to the drain pipe. A rubber sealing ring is provided between the threaded cap and the drain pipe to fill the gap between them. By using the sealing plug to block the drain pipe, glue leakage can be prevented. At the same time, the rubber sealing ring between the threaded cap and the drain pipe can further play a sealing role.

[0010] In a preferred embodiment, mounting plates are fixedly provided on both sides of the glue collection box, and multiple evenly distributed rectangular mounting holes are opened on the top of the two mounting plates. When installing the glue collection box, the worker passes multiple bolts through the multiple rectangular mounting holes respectively, thereby improving the connection between the glue collection box and the glue application machine.

[0011] In a preferred embodiment, two vertically distributed perforations are provided on the outer walls of both liquid inlet hoppers for mounting the rollers of the adhesive application machine.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model collects excess glue on paper through an inlet hopper and a guide hopper. At the same time, it drives two spiral augers to rotate synchronously with the help of a waterproof motor and belt assembly. The thrust generated by the spiral augers can push the glue to flow downwards quickly. On the one hand, it can accelerate the flow rate of the glue and prevent it from overflowing from the inlet hopper. On the other hand, it can agitate the glue at the filter screen to avoid impurities clogging the filter screen, thereby improving the filtration rate.

[0014] 2. By sealing the drain pipe with a plug, external dust and impurities can be prevented from contaminating the inside of the glue collection box when the equipment is not in use, and leakage can be avoided when collecting glue. A rubber sealing ring is installed between the threaded cap and the drain pipe to further enhance the sealing performance. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Refer to the instruction manual appendix Figures 1-5This utility model provides a glue collection mechanism for an offset printing paper gluing machine, including a glue collection box 1. Both sides of the top of the glue collection box 1 are connected to liquid inlet hoppers 2. Each of the two liquid inlet hoppers 2 is equipped with an anti-clogging component 3. The anti-clogging component 3 includes a spiral auger 31. The two spiral augers 31 are mounted inside the glue collection box 1 via bearings and are connected by a connecting component 32. Specifically, the connecting component 32 includes a waterproof motor 321. The outer wall of the waterproof motor 321 is fitted with a sealing cover 322, which is fixed inside the liquid inlet hopper 2. The bottom end of the output shaft of the waterproof motor 321 is fixed to the top end of one of the spiral augers 31. The two spiral augers 31 are connected by a belt assembly 323, which is located within a through hole 7.

[0024] The top and bottom walls of the glue collection box 1 are both set as inclined surfaces sloping towards the center. Two symmetrically distributed frame plates 4 are fixed inside the glue collection box 1, and the two frame plates 4 are both located between two spiral augers 31. A filter screen 5 is fixed inside the frame plate 4. A guide bucket 6 is fixed between the two liquid inlet hoppers 2, and the guide bucket 6 is connected to the inside of the two liquid inlet hoppers 2. A through hole 7 is opened inside the guide bucket 6.

[0025] Two vertically distributed perforations 15 are provided on the outer walls of the two liquid inlet hoppers 2 for installing the rollers of the glue application machine. A drain pipe 8 is passed through the center of the bottom end of the glue collection box 1, and the drain pipe 8 is connected to the inside of the glue collection box 1.

[0026] In actual use, the staff first installs the glue collection box 1 and the liquid inlet hopper 2 on the glue application machine, and makes the two liquid inlet hoppers 2 cover the two sides of the roller shaft respectively. The excess glue squeezed out by the roller shaft flows into the inside of the liquid inlet hopper 2 along the paper. After some glue falls into the guide hopper 6, it flows into the inside of the liquid inlet hopper 2. Then the glue in the liquid inlet hopper 2 flows into the glue collection box 1. At the same time, the waterproof motor 321 drives the spiral auger 31 connected to it to rotate. The two spiral augers 31 rotate synchronously under the drive of the belt group 323, so that the glue in the liquid inlet hopper 2 flows into the inside of the glue collection box 1 quickly, avoiding the glue from overflowing. After the glue passes through the filter screen 5 in the two frame plates 4, it is finally discharged from the drain pipe 8.

[0027] Refer to the instruction manual appendix Figure 5 The drain pipe 8 is provided with a sealing plug 9 inside. A vertical rod 10 is fixedly provided at the bottom of the sealing plug 9. A threaded cap 11 is movably connected to the bottom end of the vertical rod 10. The threaded cap 11 is threadedly connected to the drain pipe 8, and a rubber sealing ring 12 is provided between the threaded cap 11 and the drain pipe 8 to fill the gap between them. By using the sealing plug 9 to block the drain pipe 8, the leakage of glue can be prevented. At the same time, the rubber sealing ring 12 between the threaded cap 11 and the drain pipe 8 can further play a sealing role.

[0028] like Figure 1 As shown, mounting plates 13 are fixed on both sides of the glue collection box 1, and multiple evenly distributed rectangular mounting holes 14 are opened on the top of the two mounting plates 13. When installing the glue collection box 1, the workers pass multiple bolts through the multiple rectangular mounting holes 14 respectively, which can improve the connection between the glue collection box 1 and the glue application machine.
