Description

Technical Field

[0001] This utility model relates to the field of book printing technology, specifically to an automatic silicone oil spraying device at the top seal of perfect binding. Background Technology

[0002] Currently, in traditional perfect binding, the book sealing process often combines mechanical pressing and glue application. In this process, glue is typically applied using mechanical glue applicator, followed by pressing the cover to the book block. However, traditional glue applicator equipment often uses a fixed amount of glue applied, making precise control impossible once the glue is extruded. Common glue applicators include roller-type and spray-type, the former applying the glue using a roller, and the latter using a nozzle.

[0003] In this traditional technical approach, the lack of precise spraying control often makes it difficult to adjust the amount of adhesive, leading to potential glue overflow at the contact surface between the spine or cover and the book block. Furthermore, during the gluing process, the adhesive cannot be evenly applied to the spine and binding area, easily resulting in localized glue accumulation or adhesion, ultimately leaving excess adhesive residue at the bottom of the book and an unsightly finished product. These problems affect the overall quality of the book, increasing rework and scrap rates during production. Therefore, silicone oil needs to be sprayed at the top seal of the perfect binding to prevent glue overflow and sticking.

[0004] Traditional glue coating equipment lacks effective control over glue uniformity, especially on high-speed production lines where excess glue overflow is difficult to avoid. Ineffective glue distribution at the spine and sealing areas not only leads to material waste but also affects the usability and appearance of the books due to excessive glue adhesion. Furthermore, the high viscosity of the glue during coating and lamination often causes the finished products to stick together during demolding, increasing the complexity of subsequent processing and production time. Therefore, achieving precise glue coating, ensuring uniform spraying in the sealing area, and avoiding glue overflow and product sticking are key areas for improvement in existing technologies. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art or related technologies.

[0006] This utility model relates to an automatic silicone oil spraying device for the sealing section of adhesive binding. The device includes an oil injection cylinder, a sealing spray plate, and a pressing assembly. A sealing plate seat is fixedly installed on one side of the oil injection cylinder, and an oil guide baffle is fixedly installed on the inner side of the oil injection cylinder, with an oil cavity between the oil guide baffle and the sealing plate seat. An oil nozzle communicating with the upper sealing spray plate is opened on the surface of the sealing plate seat, and an oil coating strip is provided on the surface of the upper sealing spray plate. Furthermore, a shaft is rotatably mounted on the surface of the oil injection cylinder, and one end of the shaft is fixedly connected to an inclined guide plate rotatably mounted inside the oil injection cylinder. The pressing assembly includes a positioning plate, hydraulic seats, and a guide plate. The guide plate is fixedly installed inside the oil injection cylinder, and several hydraulic seats are evenly distributed circumferentially, with one end fixedly installed on the surface of the positioning plate and the other end provided with a connecting rod. The connecting rod passes through the surface of the guide plate and slides against the surface of the inclined guide plate. The positioning plate is fixedly installed on the surface of the oil guide baffle, and the surface of the oil guide baffle has a drain valve hole corresponding to and penetrating the surface of the oil guide baffle. The surface of the oil guide baffle is equipped with an oil drain valve corresponding to the drain valve hole, and one side of the oil guide baffle has an inlet hole facing the opposite inclined guide plate. The surface of the positioning plate is equipped with a one-way inlet valve corresponding to the inlet hole.

[0007] Description of working effect: Through the design of the above structure, the precise spraying of silicone oil in the encapsulation process is realized, ensuring the control of the spraying amount and the adjustment of the spraying rate, so as to effectively avoid the problem of glue overflow and sticking at the bottom of the books, making the finished books and periodicals neater and more beautiful.

[0008] In a preferred embodiment, this invention can be further configured such that a quantitative spraying of silicone oil is achieved through the cooperation of an oil injection cylinder and a pressing component. The inclined guide plate drives the connecting rod, causing the hydraulic seat to periodically compress and rebound, ensuring that the amount and frequency of oil spraying are controllable, thereby avoiding finished product defects caused by excess adhesive.

[0009] In a preferred embodiment, this invention can be further configured such that: by utilizing the design of an oil-guiding baffle and controlling the internal oil pressure, the silicone oil can be evenly sprayed onto the encapsulation area. The lubricating properties of the silicone oil effectively reduce the adhesion of excess adhesive, resulting in a clean and residue-free surface on the finished book. The oiling strip has a sponge strip structure, which ensures that the silicone oil is evenly distributed in the book encapsulation area, achieving uniform application and further improving the coating effect.

[0010] Specifically, an oil pressure transition is achieved by setting a cavity inside the oil guide baffle. Under the deformation of the oil pressure seat, the internal pressure changes back and forth. Through the cooperation of the inlet hole and the one-way inlet valve plate, a negative pressure is generated inside the oil guide baffle, which guides the oil into the interior of the oil guide baffle in one direction. With the connection between the drain valve hole and the oil pressure seat at one end, the pressure inside the oil guide baffle is connected, allowing the oil in the oil pressure seat and the inner cavity of the oil guide baffle to flow freely. Furthermore, through the cooperation of the drain valve hole and the oil release valve plate on the other side, the oil pressure inside the oil guide baffle is released through the deformation of the oil release valve plate as the oil pressure increases.

[0011] In a preferred embodiment, this utility model can be further configured such that: one side of the inclined guide plate is sloping, and one end of the connecting rod slides against the sloping surface of the inclined guide plate, so that the hydraulic seat can perform precise periodic compression during operation and achieve stable spraying.

[0012] In a preferred embodiment, this utility model can be further configured such that: one side of the positioning plate is in sealed contact with the surface of the oil guide baffle, and the end of the hydraulic seat is in sealed contact with the surface of the drain valve hole, thereby ensuring that there is no leakage of oil during the introduction process and that the spraying operation is stable and reliable.

[0013] In a preferred embodiment, the present invention can be further configured such that the hydraulic base is a rubber component and has a stepped bucket-shaped structure, which can effectively undergo elastic deformation during operation to ensure the smoothness and stability of silicone oil spraying.

[0014] In a preferred embodiment, this utility model can be further configured as follows: a one-way inlet valve plate and an inlet hole are used for one-way introduction of oil into the inner cavity of the oil guide baffle, and the drain valve hole and the drain valve plate are used for one-way flow of oil from the inner cavity of the oil guide baffle to the oil cavity, ensuring that the internal oil can be accurately transmitted and achieving effective spraying.

[0015] The beneficial effects achieved by this utility model are as follows:

[0016] 1. In this utility model, the quantitative spraying of silicone oil is achieved through the cooperation of the oil injection cylinder and the pressing component. The inclined guide plate drives the connecting rod, causing the hydraulic seat to periodically compress and rebound, ensuring that the amount and frequency of oil spraying are controllable, thereby avoiding finished product defects caused by excess glue.

[0017] 2. In this invention, the design of the oil-guiding baffle ensures that the silicone oil can be evenly sprayed onto the encapsulation area by controlling the internal oil pressure. The lubricity of the silicone oil effectively reduces the adhesion of excess adhesive, resulting in a clean and residue-free surface on the finished book. The oiling strip has a sponge strip structure, which ensures that the silicone oil is evenly distributed in the book encapsulation area, achieving uniform application and further improving the coating effect.

It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0029] The following is in conjunction with the appendix Figures 1-5 This invention describes an automatic silicone oil spraying device for the sealing of adhesive binding tubes, provided in some embodiments of the present invention.

[0030] This utility model provides an automatic silicone oil spraying device for the top sealing of adhesive binding tubes, including an oil injection cylinder 100, a top sealing spray plate 200, and a pressing assembly 300. In the following specific embodiments, the structure and working process of each component will be further described in detail to ensure that this utility model can achieve the expected technical effects.

[0031] Example 1: Basic Structural Design

[0032] In this embodiment, the present invention includes an oil injection cylinder 100, on one side of which a sealing plate seat 130 is fixedly installed. An oil guide baffle 140 is fixedly installed on the inner side of the oil injection cylinder 100, and an oil cavity 131 is provided between the oil guide baffle 140 and the sealing plate seat 130. An oil nozzle 132 communicating with an upper sealing spray plate 200 is provided on the surface of the sealing plate seat 130, and an oiling strip 210 is provided on the surface of the upper sealing spray plate 200. Furthermore, a shaft 110 is rotatably mounted on the surface of the oil injection cylinder 100, and one end of the shaft 110 is fixedly connected to an inclined guide plate 120 rotatably mounted inside the oil injection cylinder 100. The present invention also includes a pressing assembly 300, which includes a positioning plate 310, a hydraulic seat 320, and a guide plate 330. The guide plate 330 is fixedly installed inside the oil injection cylinder 100, and several hydraulic seats 320 are evenly distributed in a circumferential direction, one end of which is fixedly installed on the surface of the positioning plate 310, and the other end is provided with a connecting rod 321. The connecting rod 321 passes through the surface of the guide plate 330 and slides against the surface of the inclined guide plate 120. The positioning plate 310 is fixedly installed on the surface of the oil guide baffle 140. The surface of the oil guide baffle 140 is provided with a drain valve hole 143 that corresponds to the hydraulic seat 320 and passes through the surface of the oil guide baffle 140. The surface of the oil guide baffle 140 is provided with an oil drain valve plate 141 that corresponds to the drain valve hole 143. One side of the oil guide baffle 140 is provided with an inlet hole 142 facing the side of the inclined guide plate 120. The surface of the positioning plate 310 is provided with a one-way inlet valve plate 311 that corresponds to the inlet hole 142.

[0033] Extended Explanation: In this embodiment, the oil injection cylinder 100 is connected to a silicone oil storage tank or other silicone oil delivery pipeline. The shaft 110 is connected to a drive motor. Rotation of the shaft 110 drives the inclined guide plate 120 to rotate inside the oil injection cylinder 100. The rotation of the inclined guide plate 120 guides the connecting rod 321 to deform the hydraulic seat 320, causing the hydraulic seat 320 to generate oil output during compression deformation. The oil is guided into the oil chamber 131 through the drain valve hole 143, and finally precisely sprayed through the nozzle 132 and the coating strip 210. This design can precisely control the amount and frequency of silicone oil spraying, effectively solving the problem of glue overflow at the bottom of perfect bound books.

[0034] Example 2: Optimizing spray control and uniform coating

[0035] In this embodiment, the basic structure has been optimized and improved to enhance the uniformity and stability of the coating. The surface design of the upper sealing spray plate 200 incorporates an oil-absorbing and uniformly distributed oiling strip 210. This component has a sponge-like structure, which better distributes the silicone oil evenly across the encapsulation area, ensuring consistent coating coverage. Furthermore, this embodiment improves the material of the hydraulic base 320, using a more elastic material to more precisely control oil output during deformation.

[0036] Extended Explanation: A cavity is designed inside the oil guide baffle 140 to facilitate oil pressure transition. The pressure change generated by the deformation of the oil pressure seat 320 guides the oil through the inlet hole 142 and the one-way inlet valve 311 into the interior of the oil guide baffle 140. The design of the inner cavity of the oil guide baffle 140 ensures that a negative pressure is formed during the deformation recovery process of the oil pressure seat 320, guiding the oil in a one-way direction. During the spraying process, the silicone oil is guided to the oil chamber 131 by the drain valve hole 143, and finally evenly sprayed onto the book packaging area through the spray nozzle 132 and the coating strip 210. Working principle and usage process of this utility model:

[0037] The oil injection cylinder 100 is connected to a silicone oil storage tank or other silicone oil delivery pipeline. The shaft 110 is connected to a drive motor. The rotation of the shaft 110 drives the inclined guide plate 120 to rotate inside the oil injection cylinder 100. The rotation of the inclined guide plate 120 guides the connecting rod 321 to push the hydraulic seat 320 to deform. Under the elastic deformation of the hydraulic seat 320, a reciprocating deformation motion is formed. During the compression deformation, the internal cavity of the hydraulic seat 320 decreases, pressing the oil inside the hydraulic seat 320 through the drain valve hole 143 and then entering the oil chamber 131 under the release of the oil release valve plate 141. The oil pressure inside the oil chamber 131 increases, causing the oil to pass through the spray nozzle 132 and the oiling strip 210 and be sprayed onto the top seal of the printed material. Afterwards, under the continuous rotation of the inclined guide plate 120, the connecting rod 321 disengages from the abutment action with the inclined surface of the inclined guide plate 120, and the hydraulic seat 320 elastically... Upon restoration, the internal cavity expands, generating negative pressure. The drain valve plate 141 abuts against the drain valve hole 143, effectively sealing the drain valve hole 143. Under the action of the hydraulic seat 320, the oil inside the injection cylinder 100 passes through the one-way inlet valve plate 311 and the inlet hole 142, then enters the hydraulic seat 320 through the drain valve hole 143, completing the filling of the hydraulic seat 320. Under the rotation of the inclined guide plate 120, the reciprocating deformation motion of multiple hydraulic seats 320 generates continuous oil input and output, causing the oil on one side of the hydraulic seat 140 to be introduced into the oil chamber 131 on the other side of the hydraulic seat 140, and then discharged through the nozzle 132 and the oiling strip 210. The number of rotations and the rotation speed of the shaft 110 are controlled to achieve the control of the oil spray quantity and the oil spray rate of the oiling strip 210.
