Description

Technical Field

[0001] This utility model relates to the field of perfect binding line technology, and in particular to a glue supply device for perfect binding lines. Background Technology

[0002] In the perfect binding production process, the glue supply device is a key piece of equipment to ensure the quality and efficiency of perfect binding. Currently, some equipment requires a large amount of glue to adapt to large-scale perfect binding, and therefore adopts a continuous glue supply device, such as the continuous glue supply device with application number 202322124926.9. This device can continuously supply glue from the glue supply chamber outwards without stopping the machine to wait for the glue to be replenished, ensuring the continuity of glue supply, thereby improving production efficiency and the quality of glue dispensing.

[0003] However, during use, it was found that the process of switching the glue supply source by starting and stopping the valves one by one for multiple glue buckets was cumbersome. The switching process was prone to brief glue interruptions, which not only reduced glue supply efficiency but may also affect the quality of the glued finished products.

[0004] In addition, glue tends to solidify in glue buckets when left to stand, reducing its fluidity and affecting the glue supply effect. At the same time, glue residue and adhesion to the inner wall of the glue bucket are common problems, making cleaning difficult. Long-term accumulation not only increases maintenance costs but also shortens the lifespan of the glue bucket, which is detrimental to the stable operation and continuous use of the glue supply device in the binding line. Utility Model Content

[0005] Purpose of the utility model: The purpose of this utility model is to provide a glue supply device for a binding line to solve the above-mentioned shortcomings in the prior art.

[0006] Technical solution: A glue supply device for a binding line includes two glue tanks, each glue tank being connected to a glue supply chamber via a delivery pipe. A connecting sleeve is provided through the middle of each delivery pipe. An opening and closing assembly is provided inside the connecting sleeve. Each opening and closing assembly includes a second rotating shaft rotatably connected to the connecting sleeve. A baffle for controlling the flow of glue through the connecting sleeve is provided on the second rotating shaft, and the baffles inside the two connecting sleeves are arranged vertically.

[0007] As a further description of the above technical solution: the glue supply chamber is connected to an installation box via a fixing frame;

[0008] The opening and closing assembly also includes a sliding shaft disposed inside the mounting box. Two parallel sliding plates are slidably disposed on the sliding shaft, and a connecting rod is fixedly connected to each sliding plate.

[0026] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figures 1-5 A glue supply device for a binding line includes two glue tanks 1, each of which is connected to a glue supply chamber 2 via a delivery pipe 3. It should be noted that the glue inside the glue tank 1 is transported to the glue supply chamber 2 via the delivery pipe 3, and then the glue inside the glue supply chamber 2 is continuously supplied to the binding line equipment. This process is existing technology. A connecting sleeve 31 is provided through the middle of each delivery pipe 3, and an opening / closing component 5 is provided inside the connecting sleeve 31. Each set of opening / closing components 5... The system includes a second rotating shaft 511 rotatably connected to the connecting sleeve 31. The second rotating shaft 511 is equipped with a baffle 512 for controlling the flow of adhesive through the connecting sleeve 31. The two baffles 512 inside the connecting sleeve 31 are arranged vertically. It should be noted that the purpose of the vertical arrangement of the baffles 512 is to ensure that the two baffles 512 are always in an open and closed state. Rubber rings can be provided on the side of the baffles 512 to increase the sealing between them and the inner wall of the connecting sleeve 31.

[0028] As a preferred embodiment, the glue supply chamber 2 is connected to the mounting box 8 via a fixing frame 4; the opening and closing assembly 5 further includes a sliding shaft 52 disposed inside the mounting box 8, on which two parallel sliding plates 53 are slidably disposed, and each sliding plate 53 is fixedly connected to a connecting rod 56. A rack 59 is disposed at the end of the connecting rod 56 away from the sliding plate 53, and a gear 510 is disposed at the lower end of the second rotating shaft 511. The rack 59 and the gear 510 are meshed together; it should be noted that a sleeve rod 58 is provided through the mounting box 8, and the connecting rod 56 is inserted through the sleeve rod 58, which can improve the stability of the connecting rod 56 when moving and avoid the problem of bending caused by heavy load on the connecting rod 56.

[0029] As a preferred technical solution of this embodiment, the opening and closing component 5 further includes a first rotating shaft 54 ​​rotatably disposed inside the mounting box 8. The first rotating shaft 54 ​​is provided with a protrusion 55 for pushing the slide plate 53 to move. It should be noted that the end of the first rotating shaft 54 ​​is provided with a driving component for driving the first rotating shaft 54 ​​to rotate. Both manual and electric drive are possible. However, in order to make the slide plate 53 remain stationary after moving, this solution first uses a servo motor with a self-locking function.

[0030] As a preferred technical solution in this embodiment, the mounting box 8 is also provided with a reset spring 57 arranged between the mounting box 8 and the slide plate 53, so that the slide plate 53 can automatically reset after moving.

[0031] As a preferred technical solution in this embodiment, each glue bucket 1 is provided with a stirring assembly 6 inside. Each stirring assembly 6 includes a third rotating shaft 61 rotatably connected inside the glue bucket 1. It should be noted that the end of the third rotating shaft 61 is provided with a driving component, preferably a motor driving the third rotating shaft 61 to rotate. The third rotating shaft 61 is provided with a stirring rod 62 for stirring the glue. The third rotating shaft 61 is connected to a scraper 64 through a connecting frame 63. The scraper 64 is arranged in close contact with the inner wall of the glue bucket 1 and is used to scrape off the glue on the inner wall of the glue bucket 1 during the stirring process, reducing the time that the glue stays on the inner wall of the glue bucket 1 and avoiding the problem of hard-to-clean glue that has solidified and stuck to the inner wall of the glue bucket 1.

[0032] As a preferred technical solution in this embodiment, each of the delivery pipes 3 is also provided with a valve 32, which can be closed to input glue into the glue supply chamber 2 when not in use, so as to prevent glue from dripping.

[0033] As a preferred technical solution in this embodiment, each glue bucket 1 is provided with a liquid level sensor 7 for detecting the liquid level inside the glue bucket 1. When the liquid level sensor 7 issues an alarm due to the detected liquid level being too low, and since the servo motor drives the protrusion 55 to rotate in this solution, the liquid level sensor 7 needs to be electrically connected to an external controller to control the start and stop of the servo motor. This process is existing technology and will not be described in detail.

[0034] As a preferred technical solution in this embodiment, each glue bucket 1 is provided with a glue filling port 11 for adding glue, and the glue filling port 11 is provided with a cover 12, which can cover the open end of the glue filling port 11 to prevent dust in the air from contaminating the glue.

[0035] General working principle:

[0036] First, since the two baffles 512 are in an open and closed state, the glue tank 1 corresponding to the baffle 512 in the open state first supplies glue to the glue supply chamber 2. When the glue inside the glue tank 1 reaches the bottom, the liquid level sensor 7 detects that there is no glue inside the glue tank 1, and controls the servo motor to start through the external controller, which in turn causes the first rotating shaft 54 ​​to rotate. The first rotating shaft 54 ​​drives the protrusion 55 to rotate, and the two slide plates 53 move in opposite directions under the push of the protrusion 55. Then, through the rack 59 on the connecting rod 56, the gear 510 is driven to rotate. The gear 510 drives the baffle 512 on the second rotating shaft 511 to rotate, realizing the two The baffles 512 inside each connecting sleeve 31 rotate 90 degrees, and the baffle 512 that is not in a closed state is opened, while the other one is the opposite. At this time, another glue tank 1 supplies glue into the glue supply chamber 2, and the other glue tank 1 continues to supply glue through the glue replenishment port 11. The above actions are repeated to complete the continuous glue supply. Thus, not only is a continuous glue supply achieved, but the two baffles 512 can also be controlled simultaneously by the opening and closing component 5. Compared with the existing method of starting and stopping the valve 32 one by one to replace the glue supply source, the simultaneous rotation of the two baffles 512 is more efficient, improves the continuity of glue supply, and reduces the frequency of glue supply interruption.

[0037] Furthermore, the stirring component 6 inside each glue bucket 1 can stir the glue, and the motor drives the third rotating shaft 61 to rotate. The third rotating shaft 61 drives the stirring rod 62 to rotate, which increases the fluidity of the glue and reduces the possibility of the glue solidifying. In addition, the third rotating shaft 61 also drives the connecting frame 63 to drive the scraper 64 to scrape off the glue on the inner wall of the glue bucket 1, reducing the time the glue stays on the inner wall of the glue bucket 1 and avoiding the problem of sticking and difficult cleaning.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
