Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive spraying technology for hardcover book processing, and more specifically, to an adhesive spraying device for pressing grooves in hardcover books. Background Technology
[0002] Hardcover books are a high-quality bookbinding format that uses a hard cover (usually a cardboard or leather base) and special binding techniques (such as sewn binding). The hard cover effectively resists external pressure through its rigid structure, preventing the book block from deforming or the inner pages from curling. In addition, the hard base provides conditions for the implementation of processes such as hot stamping and embossing, meeting the visual presentation requirements of collector's edition books.
[0003] Currently, in order to make the hardcover more aesthetically pleasing and easier for readers to flip through, grooves need to be pressed onto it. However, the grooves are prone to springing back after pressing. Therefore, it is necessary to spray glue on both sides of the book block transported in the three-dimensional conveyor track. After spraying glue, it can bond with the grooved part on the inside of the hardcover, thereby reducing the probability of the groove springing back. However, the grooved parts of the hardcover are different, and the thickness of the hardcover is also different. Based on this, this utility model proposes a glue spraying device that can be flexibly adjusted to prevent the groove from springing back. Utility Model Content
[0004] The purpose of this utility model is to solve the problems mentioned in the background art, and then to propose a glue spraying device for pressing grooves in hardcover books.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A glue spraying device for sealing hardcover books includes a mounting platform and a three-dimensional conveyor line. The three-dimensional conveyor line is located in the middle area of the mounting platform. The device also includes a glue spraying component and a leveling adjustment component.
[0007] The glue spraying assembly includes a glue spraying valve and a glue tank, and the glue spraying valve and the glue tank correspond one-to-one and are connected.
[0008] The horizontal adjustment components are symmetrically arranged on the mounting platform and outside the three-dimensional conveyor line, and a first pointer is provided on the horizontal adjustment components;
[0009] The first scale line is symmetrically set on the mounting platform;
[0010] The vertical adjustment component is mounted on the horizontal adjustment component, and the vertical adjustment component is equipped with a second pointer and a glue spraying component;
[0011] The second scale line is set on the mounting plate, which is fixed to the leveling adjustment assembly.
[0012] The transmitter and receiver of the through-beam photoelectric switch are respectively mounted on two sets of vertical adjustment components and are positioned opposite each other;
[0013] The mounting frame is set up on the mounting platform and above the three-dimensional conveyor line, and visual inspection components are installed on the mounting frame.
[0014] The buzzer is mounted on the mounting platform.
[0015] Furthermore, both the horizontal adjustment component and the vertical adjustment component adopt a manual lead screw structure. The vertical adjustment component, the first pointer, and the mounting plate are all set on the moving block of the horizontal adjustment component, and the second pointer, the glue spraying component, and the photoelectric switch are all set on the moving block of the vertical adjustment component.
[0016] Furthermore, the mounting bracket is symmetrically provided with multispectral ring LED light sources that are tilted and located on both sides of the visual inspection component.
[0017] Furthermore, a PP plastic container is movably mounted on the moving block of the vertical adjustment component.
[0018] Furthermore, the vertical adjustment component has a placement plate on its movable block, and T-shaped slots are symmetrically arranged on the placement plate. The bottom of the PP plastic container has T-shaped inserts that correspond to and cooperate with the T-shaped slots.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] 1. This application allows for flexible adjustment of the position of the glue spraying device according to the thickness of the hard cover and the position of the groove on the hard cover, so that the glue on the subsequent book block accurately corresponds to and bonds with the groove, thereby reducing the probability of groove rebound. Specifically, the height of the glue spraying device is manually adjusted by the vertical adjustment component with the second pointer and the second scale line, and the distance between the glue spraying device and the book block is manually adjusted by the horizontal adjustment component with the first pointer and the first scale line, so that the processing effect of the hardcover book is better and more beautiful.
[0021] 2. On this basis, an industrial camera was added to detect and identify the size of the book block in real time during the transmission process. When the size of the book block changes between different batches, it can be quickly captured and a buzzer will be triggered. At the same time, the three-dimensional conveyor line will stop working, thus reminding the staff to come and adjust the position of the glue spraying equipment to adapt to the new hard cover and complete the glue spraying of the book block.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:
[0030] like Figures 1 to 5 As shown, a glue spraying device for sealing hardcover books includes a mounting platform 1 and a three-dimensional conveyor line 2. The three-dimensional conveyor line 2 is arranged in the middle area of the mounting platform 1. It also includes a glue spraying component 3, a horizontal adjustment component 4, a first pointer 5, a first scale line 6, a vertical adjustment component 7, a second pointer 8, a second scale line 9, a photoelectric switch 10, a mounting bracket 11, a vision inspection component 12, a buzzer 13, and a controller 14.
[0031] The glue spraying assembly 3 includes a glue spraying valve and a glue tank, and the glue spraying valve and the glue tank correspond one-to-one and are connected (the glue tank is not shown in the figure). The glue spraying valve is a screw-type electric glue spraying valve. The screw-type electric glue spraying valve is an existing technology and will not be improved. It precisely controls the amount of high-viscosity glue (such as epoxy resin) through screw rotation, which is suitable for the large flow requirements of continuous glue application to the book block. Specifically, the screw is driven to rotate by a motor, forming a negative pressure sealed cavity with the stator, and the glue is drawn from the glue tank into the valve body.
[0032] The electric glue spray valve consists of the following components:
[0033] Core structural components
[0034] 1. Driver Module
[0035] Electric type: Stepper motor, precision screw, encoder (for position feedback);
[0036] 2. Fluid Control Module
[0037] Valve body: Made of SUS 304 stainless steel or anodized aluminum alloy, which is corrosion resistant and has strong pressure resistance;
[0038] Sealing components: PTFE diaphragm sheet, O-ring (to prevent glue from seeping into the gas path);
[0039] 3. Glue Dispensing Module
[0040] Needle / nozzle: Replaceable design to fit different glue line widths (flat fan-shaped nozzles are commonly used in book blocks).
[0041] Back suction mechanism: lift-type valve needle or diaphragm structure, glue cut-off response time <10ms.
[0042] The horizontal adjustment component 4 is symmetrically arranged on the mounting platform 1 and is located outside the three-dimensional conveyor line 2, and the horizontal adjustment component 4 is provided with a first pointer 5;
[0043] The first scale line 6 is symmetrically set on the mounting platform 1;
[0044] The vertical adjustment component 7 is mounted on the horizontal adjustment component 4, and the vertical adjustment component 7 is equipped with a second pointer 8 and a glue spraying component 3;
[0045] The second scale line 9 is set on the mounting plate, and the mounting plate is fixed on the horizontal adjustment component 4;
[0046] The transmitter and receiver of the through-beam photoelectric switch 10 are respectively mounted on two sets of vertical adjustment components 7 and are arranged facing each other.
[0047] Mounting frame 11 is mounted on mounting platform 1 and above three-dimensional conveyor line 2, and visual inspection component 12 (specifically an industrial camera) is installed on mounting frame 11.
[0048] Buzzer 13 is mounted on mounting platform 1.
[0049] Specific implementation of this utility model solution, such as Figure 1 , Figure 2 and Figure 5 As shown, both the horizontal adjustment component 4 and the vertical adjustment component 7 adopt a manual screw structure (the horizontal adjustment component 4 consists of a horizontal fixed plate, a first screw, a horizontal moving block, a slide groove and a first knob, the first screw and the horizontal fixed plate are threadedly connected, the horizontal moving block is rotatably connected to the end of the first screw, and the horizontal moving block is slidably engaged with the slide groove).
[0050] The vertical adjustment assembly 7 consists of a second lead screw, a vertical moving block, a guide roller, and a second knob. The second lead screw is threadedly connected to the vertical moving block, the guide roller is slidably engaged with the vertical moving block, and the end of the second lead screw is rotatably connected to the moving block of the horizontal adjustment assembly.
[0051] Both the horizontal adjustment component 4 and the vertical adjustment component 7 convert rotational motion into linear motion, thereby enabling the position adjustment of the glue spraying equipment in the front-back and height directions.
[0052] The vertical adjustment component 7, the first pointer 5, and the mounting plate are all mounted on the moving block of the horizontal adjustment component 4. The second pointer 8, the glue spraying component 3, and the photoelectric switch 10 are all mounted on the moving block of the vertical adjustment component 7.
[0053] To further improve the clarity of the book block size detection process, the above-described embodiments are further optimized, such as... Figure 3 As shown, the mounting frame 11 is symmetrically arranged with multispectral ring LED light sources 15 on both sides of the visual inspection component 12 and distributed at an angle (the multispectral ring LED light source 15 is existing technology and will not be improved. The ring light source achieves multi-angle illumination through the uniform arrangement of the LED array, which can effectively reduce the shadows caused by the vibration of the book core edge during transmission, and ensure improved outline clarity during size measurement. At the same time, the high-brightness LED of the ring light source supports microsecond-level response, and can be used with industrial cameras for high-speed shooting, which can adapt to the continuous movement scene of the three-dimensional conveyor line 2 and avoid size misjudgment caused by motion blur).
[0054] To reduce the probability of adhesive dripping directly onto mounting platform 1 during the adhesive spraying process, further optimizations to the above-described embodiments are made, such as... Figure 2 As shown, a PP plastic container 16 is movably mounted on the movable block of the vertical adjustment component 7;
[0055] Specifically, the vertical adjustment component 7 has a placement plate 17 on its movable block, and T-shaped slots 171 are symmetrically arranged on the placement plate 17. The bottom of the PP plastic container 16 has T-shaped inserts that correspond to and cooperate with the T-shaped slots 171 (the T-shaped inserts are shown in the figure but are not labeled).
[0056] It should be noted that the 3D conveyor line 2, vision inspection component 12, buzzer 13, through-beam photoelectric switch 10, and glue spraying assembly 3 are all electrically connected to the controller 14.
[0057] The working process of this utility model is as follows:
[0058] First, the size of the book blocks conveyed on the 3D conveyor line 2 is captured and identified by an industrial camera. Once the size of the first book block is scanned and identified, its parameters can be viewed on the display screen of the controller 14. Then, the staff selects the hard cover that matches the book block. After selection, the position of the groove on the hard cover is measured. After the groove position is measured, the height of the glue spraying equipment can be adjusted by the vertical adjustment component 7 with the second pointer 8 and the second scale line 9 so that the glue sprayed on the book block corresponds to the groove position. In this way, when the hard cover and the book block are joined, the groove can be bonded from the inside of the hard cover to reduce the probability of groove rebound. At the same time, depending on the thickness of the hard cover, the distance between the glue spraying equipment and the book block can be adjusted by the horizontal adjustment component 4 with the first pointer 5 and the first scale line 6 (if the hard cover is thicker, the glue is sprayed closer to the book block to increase the amount of glue sprayed; if the hard cover is thinner, the glue is sprayed further away from the book block to reduce the amount of glue sprayed). After the glue spraying equipment position is adjusted, the glue spraying process of this batch of book blocks can begin.
[0059] When the infrared beam of the photoelectric switch 10 is blocked by the book core during glue spraying, the photoelectric switch 10 immediately sends a signal to the controller 14 to trigger the glue spraying assembly 3 to start spraying glue. When the book core no longer blocks the infrared beam, the glue spraying stops.
[0060] When the size of the next batch of book blocks changes, it will be quickly captured by the industrial camera. The industrial camera will then send a signal to the controller 14. The controller 14 will then control the buzzer 13 to sound and the 3D conveyor line 2 to stop. The staff will then come to adjust the position of the glue spraying equipment to match the size and thickness of the new hard cover. Once the second adjustment is completed as described above, a new round of book block glue spraying production line processing can begin.
[0061] In summary, this application allows for flexible adjustment of the glue spraying equipment position based on the thickness of the hardcover and the differences in the groove positions on different hardcovers, thereby ensuring that the glue on the subsequent book block accurately corresponds to the groove, reducing the probability of groove rebound, and resulting in a better and more aesthetically pleasing finish for hardcover books.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
