Description

Technical Field

[0001] This utility model relates to the field of bookbinding equipment technology, specifically to a device for attaching spine paper to the spine of a book block. Background Technology

[0002] After the book block is processed, it needs to be sealed with hot melt adhesive on the spine to form a complete book block. When sealing the book cover, the spine paper needs to be pasted in advance, and then the cover is glued to the spine paper.

[0003] During the process of adding spine paper, a layer of glue is pre-coated on the spine paper. However, because the surface of hot melt adhesive is relatively smooth, the adhesion between the glue and hot melt adhesive on the spine paper is poor. Therefore, a layer of waste paper is pre-attached to the spine. After the waste paper is attached to the spine, it is torn off, leaving a torn part on the spine. This torn part makes the spine surface rough and can cover the hot melt adhesive. At this time, the spine paper coated with glue is adhered to the rough surface formed by the torn part, thus completing the spine paper installation.

[0004] However, in the above-mentioned processing, waste paper needs to be glued and then torn off beforehand. The spine paper cannot be directly glued to the spine. Therefore, the process of gluing and tearing off waste paper requires a lot of manual labor, resulting in low efficiency and high production cost in the process of mounting the spine paper.

[0005] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this utility model is to provide a device for attaching spine paper to the spine of a book block, in order to solve the above-mentioned technical problems. The utility model adopts the following technical solution: A book block spine pasting device includes a machine base, on which a book feeding mechanism is provided to transport the book block in a predetermined direction, wherein the spine of the book block protrudes from the book feeding mechanism during transport, and the machine base is further provided with: A feeding tray, which is rotatably mounted on one side of the machine base, is used to continuously release the spine paper; The tension reversing mechanism is used to guide the spine paper to the spine position of the book block. It includes several tension rollers arranged in an alternating manner, and a reversing unit for guiding the spine paper to convert to a vertical state opposite to the spine. The bonding mechanism is used to bond the vertically positioned spine paper to the spine of the book block. It includes a heating unit and a forming unit arranged sequentially along the direction in which the book block is conveyed. The heating unit includes a heating element that is elastically bonded to the spine of the book block to heat the part where the spine paper and the spine are in contact. The forming and bending unit is used to bend the upper and lower ends of the spine paper bonded to the spine toward the spine.

[0007] Furthermore, the commutation unit includes: A reversing roller is rotatably mounted on the machine base and is angled to guide the spine paper to form an inclined state. The guide roller is vertical and rotatable, and is adjacent to the spine of the book block.

[0008] Furthermore, the bonding mechanism also includes a crease unit located upstream of the heating unit along the direction in which the book block is conveyed. The crease unit is used to fold the upper and lower sides of the spine paper toward the surface of the book block in advance, so that the spine paper is inclined on both sides in the vertical direction of the book block.

[0009] Furthermore, the crease unit includes: The pre-folding assembly includes a pre-folding roller that is rotatably configured and elastically presses against the spine of the book block. A pre-folding groove is formed on the circumferential surface of the pre-folding roller. The two inner surfaces of the pre-folding groove are configured with an inclined structure, so that the opening of the pre-folding groove is an outwardly expanding structure. The crease assembly includes a crease roller that is rotatably configured and elastically presses against the spine of the book block. A crease groove is formed on the circumferential surface of the crease roller, the crease groove being for receiving the spine of the book block inside and for bending the spine paper attached to the spine of the book block.

[0010] Furthermore, the forming and bending unit includes a forming roller that is rotatably configured and elastically abuts against the spine of the book block. A forming groove is formed on the circumferential surface of the forming roller. The forming groove is used to accommodate the spine of the book block inside and to press the spine paper that is attached to the spine of the book block and bent.

[0011] Furthermore, the bonding mechanism also includes an elastic structure, which provides an elastic thrust toward the book block, and includes... A support pole, which is fixedly installed on the machine base; A swinging component, the middle part of which is rotatably connected to the upright, and a support rod is rotatably connected to its first end. The support rod is used to assemble the heating component / pre-folding roller / crease roller / forming roller. An elastic element is provided, with one end fixedly disposed and the other end elastically pulling the second end of the swinging element, causing the first end of the swinging element to swing toward the book block. An adjusting component includes a vertical plate and an adjusting bolt. The vertical plate is fixedly mounted on the machine base, and the adjusting bolt is threaded onto the vertical plate, with the end of the adjusting bolt abutting against the second end of the swinging component.

[0012] Furthermore, a cutting unit is also provided on the machine platform. The cutting unit cuts the continuous spine paper. The cutting unit includes a cutting motor that drives the cutter to rotate. The cutter has a fan-shaped structure, and its central end is connected to the cutting motor for transmission.

[0013] Furthermore, the cutting unit is also provided with a cleaning component, which is used to clean the spine paper adhered to the spine of the book core. The cleaning component includes a brush that is driven to a cleaning motor and rotates under the drive of the cleaning motor.

[0014] The beneficial effects of this utility model are as follows: During the spine pasting process, the book block is conveyed in a predetermined direction through the book feeding mechanism. At this time, the spine of the book block is exposed in the book feeding mechanism, making it easy to paste the spine pasting onto the spine. In this technical solution, the spine pasting is pre-rolled and placed in a feed tray, and is pulled out of the feed tray by the book feeding mechanism. It should be noted that the mechanism used to paste the spine pasting presses and adheres the spine pasting to the spine of the conveyed book block, thus allowing the spine pasting to move along with the book block during conveying, thereby pulling the spine pasting out of the feed tray. To ensure the spine pasting remains taut during conveying, the pulled-out spine pasting is sequentially passed around several tension rollers to ensure the tension of the spine pasting. Figure 1As shown, when the spine paper is pulled out by the feeding tray, it is in a horizontal state. However, the book block is laid flat. Therefore, when the spine paper is glued to the spine, it needs to be converted into a vertical state so that it can be attached to the spine. During the process of the spine paper being pulled and conveyed, it passes through the reversing unit, which gradually converts the horizontal spine paper into a vertical state and pulls it to a state close to the spine of the book block. After the spine paper passes through the heating element of the heating unit, the heating element elastically presses the spine paper onto the spine. Under the pressure and heat of the heating element, the glue on the spine paper and the hot melt glue on the spine are heated at the same time, so that the two glues are fused together, achieving the effect of gluing the spine paper onto the spine. Thus, the spine paper is pulled together with the book block. Then, under the action of the forming unit, the top and bottom ends of the spine paper are bent so that the two ends of the spine paper overlap the two sides of the book block.

[0015] This technical solution enables direct bonding of the spine paper to the spine of the book block, eliminating the need for pre-bonding and removing waste paper from the spine. This improves production efficiency and reduces production costs. The solution incorporates a heating unit and a forming unit, which simultaneously heat both the spine paper and the spine of the book block, causing the two types of adhesive to fuse together and directly bond the spine paper. The forming unit folds the two sides of the spine paper together and attaches them to the sides of the book block, ensuring the bonded spine paper remains secure and does not detach.

Detailed Implementation

[0021] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0022] This technical solution provides a spine-attaching device for book blocks. This device can directly attach the spine paper to the spine of the book block, saving the need for manual pasting and tearing of waste paper. This improves the efficiency of book block binding and greatly reduces the production cost of attaching spine paper to the book block by eliminating a process that heavily relies on manual labor.

[0023] Specifically, such as Figure 1-4As shown, this embodiment provides a spine-attaching device for a book block, including a machine base 100. A book feeding mechanism 110 is mounted on the machine base 100 to transport the book block in a predetermined direction. During transport, the spine of the book block protrudes through the book feeding mechanism 110. In this embodiment, the book feeding mechanism 110 uses a conventional conveying device; as long as it can transport the book block, the specific structure is not limited. The machine base 100 also includes a feeding tray 120, a tensioning reversing mechanism 200, and a bonding mechanism 300. The feeding tray 120 is rotatably mounted on one side of the machine base 100 to continuously release the spine paper. The tensioning and reversing mechanism 200 is used to guide the spine paper to the spine position of the book block, including several staggered tension rollers 210 and a reversing unit 220 for guiding the spine paper to a vertical state opposite to the spine; the bonding mechanism 300 is used to bond the vertically positioned spine paper to the spine of the book block, including a heating unit 310 and a forming unit 320 arranged sequentially along the direction in which the book block is conveyed. The heating unit 310 includes a heating element 311 that is elastically bonded to the spine of the book block for heating the part where the spine paper and the spine are in contact. The forming and bending unit is used to bend the upper and lower ends of the spine paper bonded to the spine towards the spine.

[0024] In this embodiment, the forming and bending unit includes a forming roller 321 that is rotatably set and elastically abuts against the spine of the book block. A forming groove 322 is formed on the circumferential surface of the forming roller 321. The forming groove 322 is used to accommodate the spine of the book block inside and to press the spine paper that is attached to the spine of the book block and bent.

[0025] After the spine paper is heated by the heating element 311 and fused to the spine of the book block, the spine passes through the forming groove 322. Therefore, under the constraint of the side walls on both sides of the forming groove 322, the upper and lower sides of the spine paper are bent and adhered to the sides of the book block, thus completing the forming process of the spine paper. At this time, by completely covering the spine of the book block with the spine paper, the reliability of the adhesion between the spine paper and the spine of the book block can be ensured. In addition to the sides of the spine facing the spine paper being adhered to, the upper and lower sides of the spine are also adhered to the spine paper, thus ensuring... To ensure the reliability of the adhesion between the spine paper and the spine, it is understandable that, during the heating process of the spine paper, the heating element 311 mainly comes into contact with the side of the spine paper facing the spine paper. However, during the heat transfer process, the top and bottom sides of the spine paper will also have a certain amount of heat. At the same time, the surfaces of the top and bottom sides of the spine will also have heat. Therefore, after the top and bottom sides of the spine paper are bent, they can be attached to the top and bottom surfaces of the book block. At the same time, the top and bottom sides of the spine paper and the top and bottom sides of the spine can be adhered to each other, thus ensuring the reliability of the adhesion between the spine paper and the spine.

[0026] During the spine pasting process, the book block is conveyed in a predetermined direction in the book feeding mechanism 110. At this time, the spine of the book block is exposed in the book feeding mechanism 110, which facilitates the pasting of the spine paper onto the spine. In this technical solution, the spine paper is pre-rolled and loaded into the feed tray 120, and is pulled out of the feed tray 120 under the traction of the book feeding mechanism 110. It should be noted that the mechanism used to complete the pasting of the spine paper presses and adheres the spine paper to the spine of the conveyed book block, so that the spine paper moves together with the book block during the conveying process, thereby pulling out the spine paper located in the feed tray 120. At this time, in order to keep the spine paper taut during the conveying process, the pulled-out spine paper is sequentially passed around several tension rollers 210 to ensure the tension of the spine paper. Figure 1 As shown, when the spine paper is pulled out by the feed tray 120, it is in a horizontal state. However, the book block is laid flat. Therefore, when gluing the spine paper to the spine, it needs to be converted into a vertical state so that it can be adhered to the spine. During the process of the spine paper being pulled and conveyed, it passes through the reversing unit 220, which gradually converts the horizontal spine paper into a vertical state and pulls it to a state close to the spine of the book block. The spine paper is then heated. After the heating element 311 of unit 310, the heating element 311 elastically presses the spine paper onto the spine. Under the pressure and heat of the heating element 311, the glue on the spine paper and the hot melt glue on the spine are heated simultaneously, thereby melting the two glues together and achieving the effect of bonding the spine paper to the spine. This allows the spine paper to be pulled along with the book block. Then, under the action of the forming unit 320, the upper and lower ends of the spine paper are bent so that the two ends of the spine paper overlap the two sides of the book block.

[0027] This technical solution enables direct bonding of the spine paper to the spine of the book block, eliminating the need for pre-bonding and removing waste paper from the spine. This improves production efficiency and reduces production costs. The solution includes a heating unit 310 and a forming unit 320, which simultaneously heat both the spine paper and the spine of the book block, causing the two types of adhesive to fuse together and directly bond the spine paper. The forming unit 320 folds the two sides of the spine paper together and attaches them to the sides of the book block, ensuring the bonded spine paper remains secure and does not detach.

[0028] In this technical solution, such as Figure 1-2As shown, an example of the specific structure of the reversing unit 220 is given, which includes a reversing roller 221 and a guide roller 222. The reversing roller 221 is rotatably mounted on the machine base 100 and is set at an angle to guide the spine paper to form an inclined state. The guide roller 222 is vertical and rotatably mounted, and the guide roller 222 is close to the spine of the book block.

[0029] During the movement of the spine paper, the inclined reversing roller 221 can gradually change the horizontal spine paper to an inclined position. After the spine paper passes over the guide roller 222, it gradually changes to a vertical position and is guided to a position corresponding to the spine of the book block, which facilitates the gluing action of the spine paper.

[0030] In this technical solution, in order to improve the reliability of the connection between the spine paper and the spine of the book block, and to facilitate the heating element 311 to heat and bond the spine paper and the spine of the book block at the same time, the bonding mechanism 300 is also provided with a crease unit 330 located upstream of the heating unit 310 along the direction in which the book block is conveyed. The crease unit 330 is used to bend the upper and lower sides of the spine paper in advance toward the surface of the book block, so that the spine paper is in an inclined state on both sides in the upper and lower direction of the book block.

[0031] In this plan, such as Figure 1-2 As shown, the crease unit 330 includes a pre-folding component 331 and a crease component 332. The pre-folding component 331 includes a pre-folding roller 3311 that is rotatably set and elastically pressed against the spine of the book block. A pre-folding groove 3312 is formed on the circumferential surface of the pre-folding roller 3311. The two inner surfaces of the pre-folding groove 3312 are set with an inclined structure, so that the opening of the pre-folding groove 3312 is an outwardly expanding structure. The crease component 332 includes a crease roller 3321 that is rotatably set and elastically pressed against the spine of the book block. A crease groove 3322 is formed on the circumferential surface of the crease roller 3321. The crease groove 3322 is used to accommodate the spine of the book block inside and to bend the spine paper attached to the spine of the book block.

[0032] By pre-folding and creasing the spine paper, it can be pre-wrapped over the spine of the book block after being stacked with it. This creates a certain covering effect between the spine paper and the spine of the book block, making the process of heating and bonding the spine paper more stable. At the same time, pre-folding and creasing the spine paper makes it easier for it to enter the forming groove 322 and be further pressed and shaped.

[0033] To ensure that the spine paper is pressed firmly against the spine of the book block after entering the bonding mechanism 300 and the book block spine, the bonding mechanism 300 also includes an elastic structure. This elastic structure provides an elastic thrust towards the book block, thereby pressing the spine paper firmly against the spine. Specifically, this elastic structure has multiple units corresponding to the heating unit 310, forming unit 320, pre-folding component 331, and crease component 332, and provides elastic thrust to each unit. In this technical solution, as shown... Figure 3 As shown, the elastic structure includes a vertical rod 341, a swinging member 342, an elastic member 343, and an adjusting member 344. The vertical rod 341 is fixedly mounted on the machine base 100. The middle part of the swinging member 342 is rotatably connected to the vertical rod 341, and its first end 3421 is rotatably connected to a support rod. The support rod is used to assemble the heating element 311 / pre-folding roller 3311 / crease roller 3321 / forming roller 321. One end of the elastic member 343 is fixedly mounted, and the other end elastically pulls the second end 3422 of the swinging member 342, so that the first end 3421 of the swinging member 342 swings towards the book core. The adjusting member 344 includes a vertical plate 3441 and an adjusting bolt 3442. The vertical plate 3441 is fixedly mounted on the machine base 100, and the adjusting bolt 3442 is threadedly connected to the vertical plate 3441, with the end of the adjusting bolt 3442 abutting against the second end 3422 of the swinging member 342.

[0034] In this technical solution, the elastic element 343 is a tension spring. Under the tension of the elastic element 343, the first end 3421 of the swinging element 342 swings towards the spine of the book core, thereby enabling the heating element 311 / pre-folding roller 3311 / crease roller 3321 / forming roller 321 to elastically press the spine paper onto the spine of the book core. Furthermore, the pressing force of the heating element 311 / pre-folding roller 3311 / crease roller 3321 / forming roller 321 on the spine paper can be adjusted by the adjusting element 344. Specifically... By screwing the adjusting bolt 3442 toward the second end 3422 of the swing member 342, the second end 3422 can be resisted to swing against the elastic member 343. At this time, the first end 3421 of the swing member 342 swings away from the spine of the book core, thereby reducing the pressing force of the heating member 311 / pre-folding roller 3311 / crease roller 3321 / forming roller 321 on the spine paper. Similarly, if it is necessary to increase the pressing force, the adjusting screw needs to be screwed in the opposite direction.

[0035] Because the spine paper is continuously glued to the spine of the book block, it needs to be cut continuously to separate the individual book blocks. Figure 1 , 4As shown, in this technical solution, a cutting unit 400 is also provided on the machine base 100. The cutting unit 400 cuts the continuous spine paper. The cutting unit 400 includes a cutting motor 401 that drives the cutter 402 to rotate. The cutter 402 has a fan-shaped structure, and its central end is connected to the cutting motor 401. When the cutting motor 401 rotates, it drives the fan-shaped cutter 402 to swing. After the blade of the cutter 402 swings to a position corresponding to the spine paper, it can cut the spine paper. When the cutter 402 swings to a position away from the spine paper, it can facilitate the conveying and movement of the book block.

[0036] Similarly, in order to clean the spine paper attached to the spine of the book block, a cleaning component 410 is also provided in the cutting unit 400. The cleaning component 410 is used to clean the spine paper attached to the spine of the book block. It includes a brush 412 that is driven to the cleaning motor 411. The brush 412 rotates under the drive of the cleaning motor 411.

Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
