Description

Technical Field

[0001] This utility model relates to the field of printing processing technology, and in particular to a perfect binding mechanism for printing. Background Technology

[0002] In the modern printing production process, binding is a crucial step, determining the final form, durability, and aesthetics of the finished product. Perfect binding, as an efficient, relatively low-cost, and widely used binding method, is commonly used in the production of paperback books, magazines, brochures, and other products. Its basic principle involves applying adhesive to the spine (binding edge) of the printed material, then bonding the adhesive-coated book pages to the cover, followed by shaping and other processes to complete the binding.

[0003] Existing perfect binding machines typically include steps such as book signing, spine processing (e.g., milling and roughening), gluing, cover pasting, preliminary shaping, and final cutting. Among these, the perfect binding mechanism is the core component for gluing, which mainly uses glue rollers to apply cold glue to the spine of the printed material.

[0004] However, traditional perfect binding mechanisms still have some shortcomings in practical applications. Existing mechanisms remove excess glue from the spine using a scraper. However, in the actual scraping process, due to the different requirements for glue amount and thickness for different types of paper, existing mechanisms are inconvenient to adjust the scraper height, making it difficult to quickly adapt to the continuous production of various specifications of products. Furthermore, when the scraper is scraping, some glue is easily left on the scraper, causing glue buildup, which can easily cause reverse contamination of the printed matter and thus reduce product quality. Utility Model Content

[0005] The purpose of this invention is to solve the problems of traditional perfect binding mechanisms being inconvenient to quickly adapt to the continuous production of products of various specifications, having poor adaptability, and being prone to glue buildup and reverse contamination, which affects product quality. Therefore, this invention proposes a perfect binding mechanism for printing and binding.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A perfect binding mechanism for printed materials includes a glue box with an opening at the top, a glue roller rotatably disposed inside the glue box, and a coating roller rotatably disposed on the top of the glue box and in contact with the glue roller. The mechanism further includes: a scraper disposed on the glue box, wherein the scraper is located above the opening; a lifting component is provided on the glue box for adjusting the scraping height of the scraper; and multiple sets of elastic balls disposed on the glue box, wherein the elastic balls are located below the scraper; and a driving component is provided on the glue box, wherein when the coating roller rotates, the driving component causes the elastic balls to strike the surface of the scraper.

[0008] To facilitate adjustment of the scraping height of the scraper, preferably, the lifting component includes a tube shell fixedly connected to the top of the glue box, and insert rods are fixedly connected to both sides of the scraper. The insert rods are inserted into the tube shell, and the tube shell is provided with fasteners for positioning the insert rods.

[0009] To further secure the adjusted scraper, the fastener includes a screw rod, one end of which is fixedly connected to a knob. The tube shell has a threaded groove communicating with its inner cavity, and the screw rod is threaded into the threaded groove and abuts against the surface of the insert rod.

[0010] To precisely adjust the height of the scraper, the surface of the insertion rod is further provided with scale lines.

[0011] In order to drive the glue roller and coating roller to rotate, preferably, a servo motor is fixedly connected to the outer wall of the glue box, a drive rod is rotatably connected inside the glue box, the glue roller is fixedly connected to the drive rod, and one end of the drive rod extends outside the glue box and is fixedly connected to the output end of the servo motor.

[0012] To support the coating roller, preferably, support plates are fixedly connected to both sides of the top of the glue box, and rotating shafts are fixedly connected to both ends of the coating roller, with the rotating shafts rotatably connected to the support plates.

[0013] To enable the elastic ball to strike the scraper, the driving component further includes a vertical plate fixedly connected to the top of the glue box, a rotating rod rotatably connected to the vertical plate, the elastic ball being fixedly connected to the rotating rod by a collar, and pulleys being fixedly connected to both the rotating rod and the rotating shaft, with the two pulleys connected by a timing belt.

[0014] To further reduce the noise from impacts, the elastic ball is made of rubber.

[0015] To further protect the pulley, a protective shell is fixedly connected to the top of the glue box, and the pulley is located inside the protective shell.

[0016] To facilitate inspection and maintenance of the glue box, preferably, an inspection port is provided on one side of the glue box, and a sealing plate for sealing the inspection port is detachably connected to one side of the glue box.

[0017] Compared with the prior art, the present invention provides a perfect binding mechanism for printing materials, which has the following beneficial effects:

[0018] 1. This perfect binding mechanism for printed materials allows for easy adjustment of the squeegee's glue-scraping height by rotating the knob and using the reference scale, thus meeting the processing requirements of different printed materials for glue layer thickness and enabling rapid adaptation to continuous production of various product specifications.

[0019] 2. The perfect binding mechanism for printed materials, through the rotation of the coating roller, can drive the elastic ball to tap the surface of the squeegee, causing the squeegee to vibrate. This allows the adhesive adhering to the squeegee surface during the application of adhesive to drip quickly into the glue box. This not only improves the utilization rate of the adhesive but also prevents the accumulation of adhesive on the squeegee surface from back-contaminating the printed materials, thus helping to improve the quality of the perfect binding.

[0020] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model solves the problems of traditional perfect binding mechanisms being inconvenient to quickly adapt to the continuous production of various product specifications, having poor adaptability, and being prone to glue buildup and reverse contamination, which affects product quality.

[0029] Example:

[0030] Reference Figures 1-5 This utility model provides a perfect binding mechanism for printed materials, including a glue box 1 with an opening 2 at the top, a glue roller 4 rotatably disposed inside the glue box 1, a coating roller 3 rotatably disposed at the top of the glue box 1 and tightly fitted to the glue roller 4, an inspection port on one side of the glue box 1, and a sealing plate 11 for sealing the inspection port detachably connected to one side of the glue box 1 by screws, so as to facilitate inspection and maintenance of the glue box 1. It also includes a scraper 5 disposed on the glue box 1 for scraping off excess glue from the spine of the printed materials. The coating material falls into the glue box 1 through the opening 2. The scraper 5 is located above the opening 2. The glue box 1 is equipped with a lifting component to adjust the scraping height of the scraper 5. Multiple sets of elastic balls 7 are set on the glue box 1. The number of elastic balls 7 is 3 to 6 sets. In this mechanism, 4 sets are preferred. The elastic balls 7 are located below the scraper 5. The glue box 1 is equipped with a driving component. When the coating roller 3 rotates, the driving component is used to make the elastic balls 7 strike the surface of the scraper 5. The elastic balls 7 are made of rubber, which can reduce the striking noise.

[0031] Specifically, during use, the lifting mechanism allows for easy adjustment of the scraping height of the scraper 5 to meet the processing requirements of different printed materials for adhesive layer thickness. This enables rapid adaptation to continuous production of various product specifications. Through the cooperation of the rotating coating roller 3 and the driving mechanism, the elastic ball 7 can be driven to tap the surface of the scraper 5, causing the scraper 5 to vibrate. This allows the adhesive adhering to the surface of the scraper 5 during scraping to quickly drip into the glue tank 1, which not only improves the utilization rate of the adhesive but also prevents the accumulation of adhesive on the surface of the scraper 5 from back-contaminating the printed materials.

[0032] The lifting component includes a tube shell 6 fixedly connected to the top of the glue box 1. Both sides of the scraper 5 are fixedly connected to the insertion rods 61. The surface of the insertion rods 61 is provided with scale lines 9. The insertion rods 61 are inserted into the tube shell 6. The tube shell 6 is provided with fasteners for positioning the insertion rods 61. The fasteners include screws 62. One end of the screws 62 is fixedly connected to a knob 63. The tube shell 6 is provided with a threaded groove communicating with its inner cavity. The screws 62 are threadedly connected in the threaded groove and abut against the surface of the insertion rods 61.

[0033] Specifically, in use, by rotating the knob 63 and driving the screw 62 to rotate, the screw 62 moves away from the insert rod 61 under the action of the thread, thereby releasing the fixation of the scraper 5. Then, the worker can refer to the scale line 9 to pull the scraper 5 up or down to the desired height. After the adjustment is completed, the knob 63 can be rotated in the opposite direction to make the screw 62 press against the insert rod 61, thereby locking and fixing the scraper 5. This makes it easy to adjust the scraping height of the scraper 5 to meet the processing requirements of different printed materials for adhesive layer thickness, and thus can quickly adapt to the continuous production of various specifications of products.

[0034] A servo motor 41 is fixedly connected to the outer wall of the glue box 1. The servo motor 41 can be a Parker NV series or Delta ASDA-A2. A drive rod 42 is rotatably connected inside the glue box 1. The glue roller 4 is fixedly connected to the drive rod 42. One end of the drive rod 42 extends to the outside of the glue box 1 and is fixedly connected to the output end of the servo motor 41.

[0035] Specifically, during use, by starting the servo motor 41 and driving the drive rod 42 and the glue roller 4 to rotate, the glue roller 4 continuously dips into the glue box 1 and rotates to wrap the glue around its circumference. At the same time, the glue is transferred to the surface of the coating roller 3 and drives it to rotate together. When the printed matter is conveyed on the binding machine and slides over the surface of the coating roller 3, cold glue can be applied to the spine of the printed matter conveyed on the binding machine.

[0036] Support plates 31 are fixedly connected to both sides of the top of the glue box 1, and rotating shafts 32 are fixedly connected to both ends of the coating roller 3. The rotating shafts 32 are rotatably connected to the support plates 31.

[0037] Specifically, the support plate 31 and the rotating shaft 32 are arranged to support the coating roller 3, allowing it to rotate under force.

[0038] The driving component includes a vertical plate 8 fixedly connected to the top of the glue box 1, a rotating rod 81 rotatably connected to the vertical plate 8, an elastic ball 7 fixedly connected to the rotating rod 81 by a collar, and pulleys 82 fixedly connected to both the rotating rod 81 and the rotating shaft 32, with the two pulleys 82 connected by a timing belt. A protective shell 10 is fixedly connected to the top of the glue box 1, and the pulleys 82 are located inside the protective shell 10 to shield the pulleys 82 and improve the safety of the mechanism.

[0039] Specifically, when the coating roller 3 rotates, it can also drive the rotating shaft 32, pulley 82 and rotating rod 81 to rotate together, which can drive the elastic ball 7 to knock on the surface of the scraper 5, causing the scraper 5 to vibrate. This allows the adhesive adhering to the surface of the scraper 5 to drip quickly into the glue box 1, which can not only improve the utilization rate of the adhesive, but also prevent the adhesive from accumulating on the surface of the scraper 5 and back-contaminating the printed matter, thus helping to improve the quality of product binding.

[0040] Working principle: In the process of using this perfect binding mechanism for printed matter, the mechanism is first fixedly installed in a suitable position on the perfect binding machine to cooperate with other mechanisms. By starting the servo motor 41 and driving the drive rod 42 and the glue roller 4 to rotate, the glue roller 4 continuously dips into the glue box 1 and rotates to wrap the glue around its circumference. At the same time, the glue is transferred to the surface of the coating roller 3 and drives it to rotate together. When the printed matter is conveyed on the perfect binding machine and slides over the surface of the coating roller 3, cold glue can be applied to the spine of the printed matter conveyed on the perfect binding machine. The excess glue on the spine of the printed matter can be scraped off by the scraper 5. Then the printed matter after scraping the glue is conveyed to the next process, the cover.

[0041] Furthermore, during the processing, when the coating roller 3 rotates, it can also drive the rotating shaft 32, pulley 82 and rotating rod 81 to rotate together, which can drive the elastic ball 7 to knock on the surface of the scraper 5, causing the scraper 5 to vibrate. This allows the adhesive adhering to the surface of the scraper 5 to drip quickly into the glue box 1, which can not only improve the utilization rate of the adhesive, but also prevent the adhesive from accumulating on the surface of the scraper 5 and causing reverse contamination of the printed matter, thus helping to improve the quality of the product binding.

[0042] In addition, during use, by rotating the knob 63 and driving the screw 62 to rotate, the screw 62 is moved away from the insert rod 61 under the action of the thread, thereby releasing the fixation of the scraper 5. Then, the worker can refer to the scale line 9 to pull the scraper 5 up or down to the desired height. After the adjustment is completed, the knob 63 can be rotated in the opposite direction to make the screw 62 press against the insert rod 61, thereby locking and fixing the scraper 5. This makes it easy to adjust the scraping height of the scraper 5 to meet the processing requirements of different printed materials for adhesive layer thickness, and thus can quickly adapt to the continuous production of various specifications of products.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
