Technical Field

[0001] This invention relates to the field of binding coil production equipment technology, specifically to a binding paper coil forming machine and a binding paper coil forming process. Background Technology

[0002] Currently, in the field of loose-leaf binding, it can be divided into perfect binding, staple binding, and spiral binding. Spiral binding generally involves threading the binding thread through the binding hole of the book, so that the loop on the binding thread hooks onto the book, thereby preventing the book from falling off.

[0003] Existing binding coil production equipment is mainly designed for the production of binding iron coils or binding glue coils. Binding paper coils are more environmentally friendly than binding iron coils and binding glue coils, and therefore are more in line with the future development trend of binding coils. However, since the existing binding coil production equipment is not suitable for producing binding paper coils, it is necessary to develop a device that can produce binding paper coils. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a binding paper coil forming machine and a binding paper coil forming process, which enables automated production of finished binding paper coils by processing plate-shaped paper toothed strips.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0019] A binding paper coil forming process, wherein the binding paper coil forming process uses the aforementioned binding paper coil forming machine, and the binding paper coil forming process includes the following steps:

[0077] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0078] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0079] like Figure 1-18 As shown, this invention discloses a binding paper coil forming machine, used for forming... Figure 1 The plate-shaped paper toothed belt 100 is processed into Figure 2 The curved paper toothed strip 102 in the middle, and then... Figure 2 The curved paper toothed belt 102 is formed by processing. Figure 3The finished binding paper coil 103 includes a plate-shaped toothed strip 100 with a plurality of paper teeth 101 spaced apart on one side. The plurality of paper teeth 101 are distributed along the length direction of the plate-shaped toothed strip 100. The plate-shaped toothed strip 100 can be obtained by continuously punching out the plurality of paper teeth 101 on one side of the plate-shaped paper strip using a punching device. The finished binding paper coil 103 includes a plate portion 104, a coil portion 105, and a connecting portion 106. The two ends of the coil portion 105 are integrally formed with the plate portion 104 and the connecting portion 106, respectively. There is a gap 107 between two adjacent loop portions 105. In addition, one side surface of the plate-shaped paper toothed tape 100 is coated with an adhesive layer. After the binding paper coil product 103 is formed, the adhesive layer is located on the side surface of the plate portion 104 facing the connecting portion 106, the inner surface of the loop portion 105, and the side surface of the connecting portion 106 facing the plate portion 104. The adhesive layer allows the plate portion 104 and the connecting portion 106 to be fixed by ultrasonic welding in subsequent binding. The adhesive layer can also be applied before the plate-shaped paper tape is punched.

[0080] The binding paper coil forming machine includes a frame 10, and a paper toothed belt unwinding mechanism 11, a paper toothed belt material trough 12, a paper toothed belt guiding assembly 13, a paper toothed belt preheating mechanism 15, a paper toothed belt pre-bending mechanism 20, a paper coil hot pressing forming mechanism 30, a paper coil cooling and shaping mechanism 40, and a paper coil conveying mechanism 50 arranged sequentially on the frame 10. For ease of understanding and explanation, in this invention, the conveying direction of the plate-shaped paper toothed belt 100 is defined as forward.

[0081] The paper toothed belt unwinding mechanism 11 is an unwinding reel. It can be understood that the present invention can actively release the plate-shaped paper toothed belt 100 by directly driving the unwinding reel with a motor, or by using the paper coil conveying mechanism 50 as a power source to move and release the plate-shaped paper toothed belt 100 from the unwinding reel, that is, the unwinding reel passively releases the plate-shaped paper toothed belt 100.

[0082] The paper toothed belt preheating mechanism 15 is provided with a preheating channel 16 through which the plate-shaped paper toothed belt 100 passes. The paper toothed belt preheating mechanism 15 is used to heat the plate-shaped paper toothed belt 100, thereby reducing the hardness of the plate-shaped paper toothed belt 100, so that the pre-pressing effect of the paper toothed belt preheating mechanism 15 on the plate-shaped paper toothed belt 100 is better. Specifically, the paper toothed belt preheating mechanism 15 includes an upper heating plate (not shown) and a lower heating plate (not shown). The lower heating plate is installed on the frame 10, and the preheating channel 16 is provided between the upper heating plate and the lower heating plate.

[0083] The paper toothed belt guide assembly 13 is equipped with guide wheels 14. The number of guide wheels 14 can be set according to production needs. The guide wheels 14 enable the plate-shaped paper toothed belt 100 to be smoothly guided to the preheating channel 16. The paper toothed belt unwinding mechanism 11 and the paper toothed belt guide assembly 13 are both higher than the paper toothed belt trough 12. The paper toothed belt trough 12 extends in the front-back direction. The bottom of the paper toothed belt trough 12 is equipped with a sensor (not shown) for detecting whether there is paper toothed belt in the paper toothed belt trough 12. The sensor is electrically connected to the paper toothed belt unwinding mechanism 11. Specifically, the sensor is a contact sensor. During operation, if the sensor does not detect paper teeth... When there is a plate-shaped toothed paper belt 100 in the feed trough 12, the paper belt unwinding mechanism 11 starts and releases the plate-shaped toothed paper belt 100, causing the plate-shaped toothed paper belt 100 to hang down into the paper belt feed trough 12. If the sensor detects that there is a plate-shaped toothed paper belt 100 in the paper belt feed trough 12, the paper belt unwinding mechanism 11 stops releasing the plate-shaped toothed paper belt 100. Thus, by setting the paper belt feed trough 12 and setting the sensor in the paper belt feed trough 12, the paper belt unwinding mechanism 11 is started or stopped using the information detected by the sensor. This ensures continuous feeding of the plate-shaped toothed paper belt 100 and avoids the problem of excessive output of the plate-shaped toothed paper belt 100 leading to accumulation.

[0084] The paper toothed belt pre-pressing bending mechanism 20 includes an upper pre-pressing mold 21, a lower pre-pressing mold 22, and a first driving component 23 arranged opposite to each other. The first driving component 23 can drive the upper pre-pressing mold 21 to move relative to the lower pre-pressing mold 22, so that the plate-shaped paper toothed belt 100 output by the paper toothed belt unwinding mechanism 11 is bent into a curved paper toothed belt 102. For example, there are two sets of the first driving component 23, and the two sets of the first driving component 23 are distributed in the front-back direction. By using two sets of the first driving component 23, it is easy to drive the longer upper pre-pressing mold 21, and the stability is good.

[0085] The paper coil hot pressing forming mechanism 30 includes a hot pressing forming upper mold 31, a hot pressing forming lower mold 32, a hot pressing forming left mold 33, a hot pressing forming right mold 34, and a first driving device. The first driving device can drive the hot pressing forming upper mold 31, hot pressing forming left mold 33, and hot pressing forming right mold 34 to move relative to the hot pressing forming lower mold 32, so that the curved paper toothed belt 102 is hot pressed to form a binding paper coil semi-finished product. The binding paper coil semi-finished product formed by the paper coil hot pressing forming mechanism 30 has the basic outline of a plate part 104, a coil part 105, and a connecting part 106. Since the binding paper coil semi-finished product has a certain internal stress, the binding paper coil semi-finished product will expand outward. Therefore, a subsequent paper coil cooling and shaping mechanism 40 is needed to cool and shape the binding paper coil semi-finished product.

[0086] The paper coil cooling and shaping mechanism 40 includes a cooling and shaping upper mold 41, a cooling and shaping lower mold 42, a cooling and shaping left mold 43, a cooling and shaping right mold 44, and a second driving device. The second driving device can drive the cooling and shaping upper mold 41, the cooling and shaping left mold 43, and the cooling and shaping right mold 44 to move relative to the cooling and shaping lower mold 42, so as to cool and harden the adhesive layer on the semi-finished binding paper coil and cool the semi-finished binding paper coil to form the finished binding paper coil 103. During the cooling process of the semi-finished binding paper coil by the paper coil cooling and shaping mechanism 40, after the adhesive layer on the semi-finished binding paper coil hardens, it can offset the internal stress of the finished binding paper coil 103, so that the finished binding paper coil 103 will not expand outward. It should be noted that an adhesive layer can also be set inside the plate-shaped paper toothed belt 100, thereby further improving the cooling and shaping effect of the finished binding paper coil 103 and making the finished binding paper coil 103 more stable after shaping.

[0087] The paper coil conveying mechanism 50 can drive the finished binding paper coil 103 away from the paper coil cooling and shaping mechanism 40, so that the finished binding paper coil 103 sequentially drives the semi-finished binding paper coil, the curved paper toothed belt 102 and the plate-shaped paper toothed belt 100 to move synchronously.

[0088] A drive assembly 60 is provided on the frame 10. The first drive component 23, the first drive device, and the second drive device are all connected to the drive assembly 60 for transmission, so that the drive assembly 60 can drive the paper toothed belt pre-pressing bending mechanism 20, the paper coil hot pressing forming mechanism 30, and the paper coil cooling and shaping mechanism 40 to work simultaneously.

[0089] Specifically, the first driving device includes a second driving assembly 35, a third driving assembly 36, and a fourth driving assembly 37. The second driving assembly 35 can drive the upper hot-pressing mold 31 to move up and down, the third driving assembly 36 can drive the left hot-pressing mold 33 to move left and right, and the fourth driving assembly 37 can drive the right hot-pressing mold 34 to move left and right. The second driving device also includes a fifth driving assembly 45, a sixth driving assembly 46, and a seventh driving assembly 47. The first driving assembly 23, the second driving assembly 35, the third driving assembly 36, the fourth driving assembly 37, the fifth driving assembly 45, the sixth driving assembly 46, and the seventh driving assembly 47 are all connected to the driving assembly 60 for transmission. By setting a driving assembly 60 on the frame 10, the first driving... The device consists of a second drive assembly 35, a third drive assembly 36, and a fourth drive assembly 37. The second drive unit consists of a fifth drive assembly 45, a sixth drive assembly 46, and a seventh drive assembly 47. The first drive assembly 23, the second drive assembly 35, the third drive assembly 36, the fourth drive assembly 37, the fifth drive assembly 45, the sixth drive assembly 46, and the seventh drive assembly 47 are all connected to the drive assembly 60 for transmission. This enables the drive assembly 60 to drive the paper toothed belt pre-bending mechanism 20, the paper coil hot pressing forming mechanism 30, and the paper coil cooling and shaping mechanism 40 to work simultaneously. This allows for the synchronous production of the curved paper toothed belt 102, the semi-finished binding paper coil, and the finished binding paper coil 103, ultimately achieving automated cyclic production of the finished binding paper coil 103.

[0090] The first drive assembly 23, the second drive assembly 35, the third drive assembly 36, the fourth drive assembly 37, the fifth drive assembly 45, the sixth drive assembly 46, and the seventh drive assembly 47 each include a rotating seat 231, a swing arm 232, and a movable seat 233. One end of the swing arm 232 is movably connected to the rotating seat 231, and the other end of the swing arm 232 is rotatably connected to the movable seat 233. The drive assembly 60 includes a rotary motor 61 and a transmission assembly. The rotary motor 61 drives all rotating seats 231 to rotate simultaneously through the transmission assembly, so that the rotating seats 231 drive the movable seat 233 to move linearly through the swing arm 232. The movable seat 233 on the first drive assembly 23 is connected to the upper pre-compression mold 21, and the movable seat 233 on the first drive assembly 23 can drive the upper pre-compression mold 21 to move. It can be understood that the second drive assembly 35, the third drive assembly 36, the fourth drive assembly 37, and the seventh drive assembly 47 also have a rotating seat 231. 45. The movable seats 233 on the sixth drive assembly 46 and the seventh drive assembly 47 are respectively connected to the corresponding hot pressing upper mold 31, hot pressing left mold 33, hot pressing right mold 34, cooling and shaping upper mold 41, cooling and shaping left mold 43, and cooling and shaping right mold 44. The operating principle and movement mode are the same as those of the first drive assembly 23, so they will not be described again. By setting a drive assembly 60 consisting of a single rotary motor 61 and a transmission assembly, the first drive assembly 23, the second drive assembly 35, the third drive assembly 36, and the fourth drive assembly 37 all include a rotary seat 231, a swing arm 232, and a movable seat 233. The rotary motor 61 drives all the rotary seats 231 to rotate simultaneously through the transmission assembly, so that the rotary seats 231 can drive the movable seat 233 to move linearly through the swing arm 232. Using a single rotary motor 61 as the power source, the structure is simple and the cost is low. It realizes the simultaneous operation of the paper toothed belt pre-pressing bending mechanism 20 and the paper coil hot pressing forming mechanism 30, with high efficiency.

[0091] Specifically, the rotating seat 231 is rotatably mounted on the frame 10 via the connecting shaft 2311, and the connecting shaft 2311 and the rotating seat 231 are integrally formed. The movable seat 233 is slidably mounted on the frame 10 via the guide post 234.

[0092] The rotating seat 231 has a T-shaped groove 2312 on the side away from the connecting shaft 2311. The extension direction of the T-shaped groove 2312 is horizontal and perpendicular to the axis of the connecting shaft 2311. A slider 235 is slidably mounted in the T-shaped groove 2312. The slider 235 can slide along the extension direction of the T-shaped groove 2312. A rotating shaft 236 is mounted on the slider 235. One end of the rotating shaft 236 extends out of the T-shaped groove 2312 and is rotatably connected to one end of the swing arm 232. The axis of the rotating shaft 236 is coaxial with the axis of the connecting shaft 2311. Specifically, one end of the T-shaped groove 2312 passes through the end face of the rotating seat 231 to form an installation inlet 2313. A cover plate 2314 is provided at the installation inlet 2313. The slider 235 can be inserted into the T-shaped groove 2312 from the installation inlet 2313. The cover plate 2314 can prevent the slider 235 from leaving the T-shaped groove 2312.

[0093] Taking the movement of the pre-compression mold 21 as an example, during operation, the rotating seat 231 rotates around the connecting shaft 2311, and the T-shaped slide 2312 rotates with the rotating seat 231. When the T-shaped slide 2312 rotates, a height difference will be generated at the position of the T-shaped slide 2312 away from the axis of the connecting shaft 2311, so that the T-shaped slide drives the slider 235 to rotate, and the slider 235 will also move up and down. The up and down movement of the slider 235 drives the swing arm 232 and the movable seat 233 to move up and down, and the movable seat 233 drives the upper pre-compression mold 21 to move up and down.

[0094] The transmission assembly includes a first transmission shaft 62, a second transmission shaft 63, and a third transmission shaft 64. The rotary motor 61 can drive the first transmission shaft 62, the second transmission shaft 63, and the third transmission shaft 64 to rotate simultaneously. The connecting shaft 2311 of the rotating seat 231 on the first drive assembly 23, the second drive assembly 35, and the fifth drive assembly 45 is drivenly connected to the first transmission shaft 62. The connecting shaft 2311 of the rotating seat 231 on the third drive assembly 36 and the sixth drive assembly 46 is drivenly connected to the second transmission shaft 63. The connecting shaft 2311 of the rotating seat 231 on the fourth drive assembly 37 and the seventh drive assembly 47 is drivenly connected to the third transmission shaft 64.

[0095] Specifically, the rotary motor 61 is fixedly mounted on the frame 10. The first drive shaft 62, the second drive shaft 63, and the third drive shaft 64 are all rotatably mounted on the frame 10. The main shaft 611 of the rotary motor 61 is provided with a drive gear 612. The third drive shaft 64 is provided with a driven gear 641 that meshes with the drive gear 612. The third drive shaft 64 is connected to the first drive shaft 62 via a first synchronous belt 65. One end of the first drive shaft 62 is connected to a fourth drive shaft 67 via a second synchronous belt 66. The rotating seat 231 on the first drive assembly 23 is connected to the fourth drive shaft 67. The other end of the first drive shaft 62 is connected to a fifth drive shaft 69 via a third synchronous belt 68. The rotating seats 231 on the second drive assembly 35 and the fifth drive assembly 45 are both connected to the fifth drive shaft 69. The main shaft 611 is connected to a sixth drive shaft 71 via a fourth synchronous belt 70. The sixth drive shaft 71 is connected to the second drive shaft 63 via a fifth synchronous belt 72.

[0096] It should be noted that the first drive assembly 23, the second drive assembly 35, the third drive assembly 36, the fourth drive assembly 37, the fifth drive assembly 45, the sixth drive assembly 46, and the seventh drive assembly 47 can also directly use a cylinder as a power source or adopt a screw + motor structure, in which case the drive assembly is omitted.

[0097] The lower end of the upper pre-pressing mold 21 is provided with a downwardly protruding bending ridge 211, which extends along the conveying direction of the plate-shaped toothed paper belt 100. The upper surface of the lower pre-pressing mold 22 is provided with a bending groove 221 corresponding to the bending ridge 211. The upper surface of the lower pre-pressing mold 22 is provided with a guide slope 222, which extends upward at an incline along the conveying direction of the plate-shaped toothed paper belt 100. The bending groove 221 is provided on the guide slope 222, and the depth of the bending groove 221 gradually increases along the conveying direction of the plate-shaped toothed paper belt 100. Specifically, the bottom of the bending groove 221 is horizontal along the conveying direction of the plate-shaped toothed paper belt 100. Furthermore, by providing a guide slope 222 on the upper surface of the lower pre-pressing mold 22, and a bending groove 221 on the guide slope 222, the guide slope 222 guides the plate-shaped paper toothed belt 100 to slide along the guide slope 222, thereby making the plate-shaped paper toothed belt 100 run more smoothly. At the same time, the depth of the bending groove 221 gradually increases along the conveying direction of the plate-shaped paper toothed belt 100, so that the bending degree of the plate-shaped paper toothed belt 100 gradually increases during the bending process, which has a gradual effect and avoids the plate-shaped paper toothed belt 100 from having an excessive bending degree in a short period of time, thus preventing damage to the plate-shaped paper toothed belt 100 near the paper toothed belt pre-pressing bending mechanism 20.

[0098] The bottom of the bending protrusion 211 and the bottom of the bending groove 221 are both provided with downward protruding arc surfaces 212. During operation, the bending protrusion 211 extends into the bending groove 221, and the bottom of the bending protrusion 211 abuts against the upper surface of the plate-shaped paper toothed belt 100, while the bottom of the bending groove 221 abuts against the lower surface of the plate-shaped paper toothed belt 100.

[0099] At least one relief groove 213 is provided at the bottom of the end of the bending protrusion 211 near the paper coil hot pressing forming mechanism 30. For example, the present invention provides three relief grooves 213, which are spaced apart along the conveying direction of the plate-shaped paper toothed belt 100. The relief grooves 213 extend upward into the upper pre-pressing mold 21. A relief mold 24 and a spring 25 are provided within the relief groove 213. The relief mold 24 is movably installed in the relief groove 213, and the spring 25 ensures that the relief mold 24 always tends to extend downward out of the relief groove 213. Specifically, the spring 25 is a compression spring 25, with its upper end abutting against the top wall inside the relief groove 213 and its lower end abutting against the relief mold 24. It can be understood that the spring 25 can also be a tension spring 25, with its upper end abutting against the relief mold 24. The die 24 is connected, and the lower end of the tension spring 25 is connected to the inner wall of the die retraction groove 213. The tension makes the die retraction mold 24 always tend to extend downward out of the die retraction groove 213. By setting the die retraction groove 213 at the bottom of one end of the bending protrusion 211, the die retraction mold 24 and the spring 25 are provided in the die retraction groove 213. After the pre-pressing of the plate-shaped paper toothed belt 100 is completed, during the demolding process of the upper pre-pressing mold 21 moving upward, the spring 25 pushes the die retraction mold. The mold 24 remains stationary, allowing the bending protrusion 211 to move upwards and detach from the curved paper toothed strip 102 before the retracting mold 24 moves upwards. Then the retracting mold 24 detaches from the curved paper toothed strip 102, so that the bending protrusion 211 is pressed against the curved paper toothed strip 102 by the retracting mold 24 during the demolding process, preventing the bending protrusion 211 from sticking to the adhesive layer on the curved paper toothed strip 102 and lifting the curved paper toothed strip 102 away from the bending groove 221.

[0100] The upper surface of the upper pre-compression mold 21 is provided with a clearance hole 214. The bottom of the clearance hole 214 is provided with a guide hole 271 communicating with the relief groove 213. The diameter of the guide hole 271 is smaller than the diameter of the clearance hole 214. The relief mold 24 is provided with an upwardly extending first guide rod 26. The first guide rod 26 is movably disposed in the guide hole 271. The upper end of the first guide rod 26 is connected to a limiting block 261. The limiting block 261 is movably disposed in the clearance hole 214. The limiting block 261 can restrict the first guide rod 26 from disengaging downward from the guide hole 271. Specifically, the pressure spring 25 is sleeved on the outside of the first guide rod 26. The lower end of the first guide rod 26 is screwed to the relief mold 24. A washer 27 is installed on the top wall inside the relief groove 213. The guide hole 271 is disposed inside the washer 27. The upper end of the pressure spring 25 abuts against the washer 27.

[0101] Heating tubes 28 are provided in both the upper pre-pressing mold 21 and the lower pre-pressing mold 22. The heating tubes 28 are electrically heated. In this invention, it is preferable that heating tubes 28 are provided in both the upper pre-pressing mold 21 and the lower pre-pressing mold 22. By providing heating tubes 28 in both the upper pre-pressing mold 21 and the lower pre-pressing mold 22, the plate-shaped paper toothed belt 100 can be heated during bending, thereby making the plate-shaped paper toothed belt 100 bend into a curved paper toothed belt 102 with better effect and higher efficiency.

[0102] The lower end of the upper hot-press forming mold 31 is provided with a hot-press forming plate 311, and the lower end of the hot-press forming plate 311 is provided with a hot-press forming column 312. Both the hot-press forming plate 311 and the hot-press forming column 312 extend in the front-back direction. The lower hot-press forming mold 32 is provided with a hot-press forming groove 321 with the opening facing upward. The hot-press forming groove 321 is a semi-circular groove. The left hot-press forming mold 33 is provided with a left hot-pressing plane 331 and a left hot-pressing arc surface 332 arranged vertically. The right hot-press forming mold 34 is provided with a right hot-pressing plane 341 and a right hot-pressing arc surface 342 arranged vertically.

[0103] The hot-press forming column 312, hot-press forming groove 321, left hot-pressing arc surface 332, and right hot-pressing arc surface 342 can be combined to form a ring portion 105 on the curved paper toothed belt 102. The hot-press forming plate 311 and the left hot-pressing plane 331 can be combined to form a plate portion 104 on the curved paper toothed belt 102. The hot-press forming plate 311 and the right hot-pressing plane 341 can be combined to form a connecting portion 106 on the curved paper toothed belt 102. It can be understood that the plate portion 104 can also be formed by the hot-press forming plate 311 and the right hot-pressing plane 341. Correspondingly, the connecting portion 106 is formed by the hot-press forming plate 311 and the left hot-pressing plane 331. This mainly depends on the position of the plate portion 104 and the connecting portion 106 on the binding paper coil 103.

[0104] Heating tubes 28 are provided in the upper hot pressing mold 31, the lower hot pressing mold 32, the left hot pressing mold 33, and the right hot pressing mold 34.

[0105] The width of the hot-press forming plate 311 gradually decreases from top to bottom. The left hot-pressing plane 331 and the right hot-pressing plane 341 are both inclined from top to bottom toward the hot-press forming plate 311. By using the left hot-pressing plane 331 and the right hot-pressing plane 341 that are inclined from top to bottom toward the hot-press forming plate 311, a trumpet-shaped opening is formed between the plate portion 104 and the connecting portion 106 on the hot-pressed binding paper coil 103. The trumpet-shaped opening makes it convenient to insert the connecting portion 106 into the binding hole on the book during subsequent production.

[0106] The lower end of the cooling and shaping upper mold 41 is provided with a cooling and shaping plate 411, and the lower end of the cooling and shaping plate 411 is provided with a cooling and shaping column 412. Both the cooling and shaping plate 411 and the cooling and shaping column 412 extend in the front-back direction. The cooling and shaping lower mold 42 is provided with an upward-opening cooling and shaping groove 421. The cooling and shaping groove 421 is a semi-circular groove. The cooling and shaping groove 421 and the hot pressing forming groove 321 are on the same straight line. The cooling and shaping left mold 43 is provided with a left-side pressing end 431. The cooling and shaping right mold 44 is provided with... With a right-side pressing end 441, during cooling and shaping, the cooling and shaping column 412, the cooling and shaping groove 421, the left-side pressing end 431, and the right-side pressing end 441 work together to cool and shape the entire binding paper coil 103. Specifically, the left-side pressing end 431 has a left-side tip 432, and the right-side pressing end 441 has a right-side tip 442. During cooling and shaping, the left-side tip 432 abuts against the connection between the plate portion 104 and the coil portion 105, and the right-side tip 442 abuts against the connection between the connecting portion 106 and the coil portion 105.

[0107] The cooling and shaping upper mold 41, cooling and shaping lower mold 42, cooling and shaping left mold 43, and cooling and shaping right mold 44 are all provided with water channels (not shown), as well as water inlet connectors 48 and water outlet connectors 49 connected to the water channels. During cooling and shaping, cold water can be continuously input into the water channels and hot water in the water channels can be output from the water outlet connector 49. Alternatively, cold water can be intermittently input into the water channels, and after cooling for a certain period of time, hot water in the water channels can be output from the water outlet connector 49.

[0108] The paper coil conveying mechanism 50 includes a conveying gear 51 and a conveying motor 52. The conveying motor 52 drives the conveying gear 51 to rotate, so that the teeth on the outer circumferential side of the conveying gear 51 actuate the coil portion 105 on the binding paper coil 103, and the coil portion 105 drives the binding paper coil 103 to move. It should be noted that the binding paper coil semi-finished product formed by the paper coil hot pressing forming mechanism 30 still has a certain strength, so that when the conveying gear 51 actuates the coil portion 105 on the finished binding paper coil 103, it can drive the binding paper coil semi-finished product to move. Specifically, the axis of the conveying gear 51 extends in the vertical direction, and the cooling and shaping lower mold 42 is provided with a cooling and shaping device on the side near the conveying gear 51. The shaping groove 421 is connected to a notch 422, which allows teeth to extend into the gap 107 between two adjacent coil portions 105 to move the coil portion 105. A second guide rod 17 is provided on one side of the conveying gear 51. The second guide rod 17 is located in the cooling and shaping groove 421 and extends along the movement direction of the binding paper coil finished product 103. The coil portion 105 can be sleeved on the second guide rod 17, and the binding paper coil finished product 103 can move along the second guide rod 17. It should be noted that during the process of the paper coil conveying mechanism 50 driving the binding paper coil finished product 103, the binding paper coil finished product 103 located on the paper coil cooling and shaping mechanism 40 will be sleeved on the cooling and shaping column 412 and move forward.

[0109] It is understood that the paper coil conveying mechanism 50 can also adopt a structure of push rod (not shown) + first drive module and second drive module. Specifically, the push rod is set on the first drive module and the first drive module is set on the second drive module. During operation, the first drive module first drives the push rod to move relative to the binding paper coil finished product 103, so that the end of the push rod extends into the gap 107 between two adjacent coils 105. Then, the second drive module drives the first drive module to move forward, so that the push rod pushes the coil 105 to move forward. The coil 105 then drives the binding coil finished product 103 to move forward along the second guide rod 17. The first drive module and the second drive module can adopt a cylinder or lead screw + motor structure.

[0110] This invention also discloses a binding paper coil forming process, wherein the binding paper coil forming process uses the aforementioned binding paper coil forming machine, and the binding paper coil forming process includes the following steps:

[0111] Step 1: Unwinding. The plate-shaped toothed paper belt 100 is released through the paper belt unwinding mechanism 11. The plate-shaped toothed paper belt 100 released by the paper belt unwinding mechanism 11 hangs down into the paper belt feed trough 12. When the sensor detects that there is a plate-shaped toothed paper belt 100 in the paper belt feed trough 12, the paper belt unwinding mechanism 11 stops releasing the plate-shaped toothed paper belt 100. When the sensor detects that there is no plate-shaped toothed paper belt 100 in the paper belt feed trough 12, the paper belt unwinding mechanism 11 releases the plate-shaped toothed paper belt 100.

[0112] Step 2: Feeding. The binding paper coil finished product 103 is driven to move a certain distance by the paper coil conveying mechanism 50. The binding paper coil finished product 103 sequentially drives the binding paper coil semi-finished product, the curved paper toothed belt 102 and the plate-shaped paper toothed belt 100 to move synchronously for a certain distance. The plate-shaped paper toothed belt 100 passes through the paper toothed belt pre-bending mechanism 20, the curved paper toothed belt 102 passes through the paper coil hot pressing forming mechanism 30, and the binding paper coil semi-finished product passes through the paper coil cooling and shaping mechanism 40. When the plate-shaped paper toothed belt 100 passes through the preheating channel 16 in the paper toothed belt preheating mechanism 15, the preheating channel 16 heats the plate-shaped paper toothed belt 100, reducing the hardness of the plate-shaped paper toothed belt 100.

[0113] Step 3: Forming. The paper toothed belt 100 is pre-pressed by the paper toothed belt pre-pressing mechanism 20 to form a curved paper toothed belt 102. The curved paper toothed belt 102 is hot-pressed by the paper coil hot-pressing forming mechanism 30 to form a binding paper coil semi-finished product. The binding paper coil semi-finished product is cooled by the paper coil cooling and shaping mechanism 40 to form a binding paper coil finished product 103.

[0114] Step 4: Repeat steps 2 to 3 above to cycle the plate-shaped paper toothed belt 100 to form the finished binding paper coil 103.

[0115] It should be noted that in this invention, the paper toothed belt unwinding mechanism 11 can release the plate-shaped paper toothed belt 100 intermittently or continuously. That is, the paper toothed belt unwinding mechanism 11 and the paper coil conveying mechanism 50 operate synchronously, and the length of the released plate-shaped paper toothed belt 100 is equal to the distance that the paper coil conveying mechanism 50 drives the finished paper coil 103 to move. In this way, the paper toothed belt trough 12 and the sensor can be eliminated.

[0116] In summary, this invention, by sequentially arranging a paper toothed belt unwinding mechanism 11, a paper toothed belt pre-bending mechanism 20, a paper coil hot pressing and forming mechanism 30, a paper coil cooling and shaping mechanism, and a paper coil conveying mechanism 50 on the frame 10, allows for the following process during production: the paper toothed belt unwinding mechanism 11 releases the plate-shaped paper toothed belt 100, and the paper coil conveying mechanism 50 drives the finished binding paper coil 103 to move. This causes the finished binding paper coil 103 to sequentially drive the semi-finished binding paper coil, the curved paper toothed belt 102, and the plate-shaped paper toothed belt 100 to move synchronously. The paper toothed belt pre-bending mechanism utilizes the paper toothed belt pre-bending mechanism... The bending mechanism 20 pre-presses the plate-shaped paper toothed belt 100 to form a curved paper toothed belt 102. The paper coil hot pressing forming mechanism 30 hot presses the curved paper toothed belt 102 to form a binding paper coil semi-finished product. The paper coil cooling and shaping mechanism 40 cools the binding paper coil semi-finished product to form a binding paper coil finished product 103. This realizes the automated production of the plate-shaped paper toothed belt 100 into the binding paper coil finished product 103. In addition, the binding paper coil finished product 103 made of paper is a renewable resource and can be degraded after being thrown away, making it more environmentally friendly.

[0117] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technology of the present invention shall still fall within the scope of the technical solution of the present invention.
