Description

Technical Field

[0001] This application relates to the technical field of printing equipment, and particularly relates to a processing device for interchangeable tear lines products. Background Art

[0002] After the printed products are printed in the printing press, it is necessary to exhaust the paper sheets to ensure higher fitting degree after folding. The common method is to open exhaust holes at the folding seams of the paper sheets through exhaust knives to ensure that the gas between the folded paper sheets is fully discharged, so as to improve the subsequent binding quality, and cut the paper sheets at the positions of the exhaust holes after binding. For some special double-row tear line products, it is necessary to set double-row tear lines on the paper sheets, and the tear lines can also play the role of exhausting gas while facilitating the tearing of the paper sheets.

[0003] During the production and processing of commercial web printing presses, it is often necessary to switch between ordinary printed products and double-row tear line printed products. Printing enterprises usually need to replace different production lines for different products, which not only increases the production cost but also reduces the production efficiency of printed products. Summary of the Utility Model

[0004] In view of the above disadvantages and deficiencies, this application provides a processing device for interchangeable tear line products.

[0005] The processing device for interchangeable tear line products provided by this application adopts the following technical solutions:

The adjusting mechanism is fixedly connected to the fixed beam. The driving mechanism is fixedly connected to the adjusting mechanism. The mounting tool holder is fixedly installed on the adjusting mechanism, and an interchangeable tear line cutter head or an exhaust cutter head is installed on the mounting tool holder. The adjusting mechanism is used to adjust the distance between the mounting tool holder and the tension roller, and the driving mechanism is used to drive the mounting tool holder to rotate on the adjusting mechanism;

[0009] By adopting the above technical solution, before processing printed products, according to the type of the product, a corresponding tear line cutter head or exhaust cutter head is fixedly installed on the mounting tool holder; the driving mechanism is adjusted so that the mounting tool holder approaches the tension roller. When processing the printed product, the tension roller rotates, and the paper moves between the tension roller and the mounting tool holder. The driving mechanism is started, and the driving mechanism drives the mounting tool holder to rotate. The tear line cutter head or exhaust cutter head on the mounting tool holder rotates synchronously, and the tear line cutter head or exhaust cutter head contacts the paper. When the mounting cutter head rotates, a tear line or exhaust holes are processed on the paper surface; the designed interchangeable tear line product processing device only needs to replace the corresponding tear line cutter head or exhaust cutter head on the mounting tool holder according to different process requirements of the product, which is convenient for improving the production efficiency of printed products and reducing production costs.

[0010] In a specific feasible implementation, the adjusting mechanism includes an adjusting cylinder and a mounting component. The adjusting cylinder includes a cylinder body and a piston rod. The cylinder body is fixedly installed on the fixed beam. One end of the piston rod is slidably arranged in the cylinder body, and the other end is fixedly connected to the mounting component; the mounting component is arranged opposite to the tension roller.

[0011] The mounting tool holder is rotatably connected to the mounting component.

[0012] By adopting the above technical solution, the provided adjusting mechanism, after the tear line cutter head or exhaust cutter head is installed, the adjusting cylinder is started, the piston rod extends out, and the mounting component is pushed to move. The mounting component drives the mounting tool holder to approach the tension roller, so as to facilitate adjusting the distance between the mounting tool holder and the tension roller. When processing printed products, it is convenient to perform corresponding tear line punching or exhaust hole punching operations according to papers of different thicknesses; the applicability of the device is improved.

[0013] In a specific feasible implementation, the mounting component includes a fixed seat and a rotating shaft. The fixed seat is arranged at the end of the piston rod far from the cylinder body. The rotating shaft passes through the fixed seat and is rotatably connected to the fixed seat. One end of the rotating shaft is coaxially and fixedly connected to the mounting tool holder, and the other end is fixedly connected to the driving mechanism.

[0014] By adopting the above technical solution, the provided mounting component, the fixed seat supports the rotating shaft. During production and processing, the driving mechanism drives the rotating shaft to rotate on the fixed seat, and the rotating shaft drives the mounting tool holder to rotate, which is convenient for realizing the processing of tear lines and exhaust holes on printed products.

[0015] In a specific feasible implementation, the mounting tool holder includes a mounting bushing, a locking bushing, a limiting sleeve, a locking member, and a fixing member; the mounting bushing is fixedly connected to the locking bushing coaxially, and both the mounting bushing and the locking bushing are coaxially sleeved on one end of the rotating shaft passing through the fixing seat; the tear line cutter disc or the exhaust cutter disc is disposed on the mounting bushing; a limiting boss is integrally provided at one end of the mounting bushing away from the locking bushing, and the limiting boss is used for fixedly limiting the tear line cutter disc or the exhaust cutter disc.

[0016] A locking groove is formed in the side wall of the locking bushing along the axial direction, and the locking groove extends to the end of the locking bushing away from the mounting bushing; a deformation joint is formed at the connection position between the locking bushing and the mounting bushing, and the deformation joint communicates with the locking groove; two locking steps are provided on the side wall of the locking bushing, and the two locking steps are located on both sides of the length direction of the locking groove.

[0017] The locking member includes a locking bolt and a locking nut. One end of the locking bolt abuts against one of the locking steps, and the other end sequentially passes through the two locking steps. The locking nut is threadedly connected to the end of the locking bolt passing through the locking steps.

[0018] The fixing member includes a fixing bolt and a fixing nut, and both the fixing bolt and the fixing nut are used to realize the fixed installation of the tear line cutter disc or the exhaust cutter disc and the mounting tool holder.

[0019] By adopting the above technical solution, the provided mounting tool holder, the mounting bushing provides an installation space for the tear line cutter disc or the exhaust cutter disc. By sleeving the tear line cutter disc or the exhaust cutter disc on the mounting bushing, it is convenient to realize the rotation of the tear line cutter disc or the exhaust cutter disc following the mounting bushing. At the same time, by threading the locking bolt through the two locking steps and threadedly connecting with the locking nut, the deformation joint reduces the constraint on the locking groove, causing the locking groove to contract, thereby deforming the locking bushing. The locking bolt presses the locking bushing against the circumferential side wall of the rotating shaft, thereby realizing the position fixation of the mounting tool holder on the rotating shaft.

[0020] In a specific feasible implementation, there are two tear line cutter discs.

[0024] In a specific feasible implementation, when processing the exhaust holes, the exhaust cutter disc is coaxially sleeved on the mounting bushing, and two second limiting sleeves are coaxially sleeved on the mounting bushing. The exhaust cutter disc is located between the two second limiting sleeves, and one of the second limiting sleeves abuts against the limiting boss;

[0025] The fixing bolt is arranged on the limiting boss, the exhaust cutter disc and the two second limiting sleeves, and the fixing nut is threadedly connected to the fixing bolt;

[0053] The implementation principle of the interchangeable tear line product processing device in Embodiment 1 of the present application is as follows: Before processing double-row tear lines on printed products, first, the first limiting sleeve 9 and two tear line cutter discs 7 are sleeved on the mounting shaft sleeve 61. The first limiting sleeve 9 is located between the two tear line cutter discs 7. One of the tear line cutter discs 7 abuts against the limiting boss 611. Then, the fixing bolt 641 passes through the limiting boss 611, the tear line cutter disc 7, and the first limiting sleeve 9 in sequence, and the fixing nut 642 is threadedly connected to the fixing bolt 641, so that the two tear line cutter discs 7 and the first limiting sleeve 9 are fixedly installed on the mounting shaft sleeve 61.

The locking bolt 631 passes through the two locking steps 623, and the locking nut 632 is threadedly connected to the locking bolt 631. The two locking bosses are located between the locking bolt 631 and the locking nut 632. Tighten the locking nut 632, and the deformation joint 622 reduces the constraint on the locking groove 621, causing the locking groove 621 to contract, so that the locking shaft sleeve 62 deforms. The locking bolt 631 presses the locking shaft sleeve 62 against the circumferential side wall of the rotating shaft 422, thereby realizing the position fixation of the mounting tool holder 6 on the rotating shaft 422.

[0054] After the tear line cutter disc 7 and the mounting tool holder 6 are fixed, start the adjusting cylinder 41. The piston rod 412 extends out of the cylinder body 411. The piston rod 412 pushes the mounting assembly 42 to move. The mounting assembly 42 drives the mounting tool holder 6 to approach the tension roller 2. The printed product is clamped between the tear line cutter disc 7 and the tension roller 2. Then, the belt is sleeved between the driving gear 53 and the driven gear 54, and the belt is tensioned so that the belt can realize the transmission between the driving gear 53 and the driven gear 54.

[0055] When producing double-row tear line printed products, the tension roller 2 rotates, and the paper moves between the tension roller 2 and the mounting tool holder 6. Start the driving motor 51. The driving motor 51 drives the driving shaft 52 to rotate. The driving shaft 52 drives the driving gear 53 to rotate. The driving gear 53 drives the driven gear 54 to rotate through the belt. The driving gear 53 drives the rotating shaft 422 to rotate. The mounting tool holder 6 provided on the rotating shaft 422 rotates synchronously. The two tear line cutter discs 7 on the mounting tool holder 6 rotate together. The tear line cutter disc 7 contacts the printed product.

The exhaust cutter disc 8 and the two second limiting sleeves 10 are located between the fixing bolt 641 and the fixing nut 642; a plurality of exhaust hole punching tool tips 81 are integrally arranged on the exhaust cutter disc 8. The exhaust hole punching tool tips 81 are evenly distributed along the circumference of the exhaust cutter disc 8. When processing the exhaust holes, the exhaust hole punching tool tips 81 are fitted in the exhaust hole punching tool tip receiving groove 22. The printed product is located between the second limiting sleeve 10 and the side wall of the tensioning roller 2. The second limiting sleeve 10 can be made of rubber material to improve the friction between the second limiting sleeve 10 and the printed product, avoid the offset of the printed product on the second limiting sleeve 10, and thus improve the processing quality of the exhaust holes.

[0059] The implementation principle of the interchangeable tear line product processing device in this Embodiment 2 is as follows: Before processing the double-row tear lines on the printed product, first, the exhaust cutter disc 8 and the two second limiting sleeves 10 are sleeved on the mounting bushing 61. The exhaust cutter disc 8 is located between the two second limiting sleeves 10. One of the second limiting sleeves 10 abuts against the limiting boss 611. Then, the fixing bolt 641 is sequentially passed through the limiting boss 611, the second limiting sleeve 10 and the exhaust cutter disc 8, and the fixing nut 642 is threadedly connected with the fixing bolt 641, so that the two second limiting sleeves 10 and the exhaust cutter disc 8 are fixedly installed on the mounting bushing 61. Then, the mounting bushing 61 and the locking bushing 62 are sleeved on the rotating shaft 422. The locking bolt 631 passes through the two locking steps 623, and the locking nut 632 is threadedly connected with the locking bolt 631. The two locking bosses are located between the locking bolt 631 and the locking nut 632. The locking nut 632 is tightened, and the deformation joint 622 reduces the constraint on the locking groove 621, so that the locking groove 621 shrinks, thereby deforming the locking bushing 62. The locking bolt 631 presses the locking bushing 62 against the circumferential side wall of the rotating shaft 422, so as to fix the position of the mounting tool holder 6 on the rotating shaft 422.

[0060] After the exhaust cutter head 8 and the mounting tool holder 6 are fixedly completed, the adjusting cylinder 41 is started. The piston rod 412 extends out of the cylinder body 411. The piston rod 412 pushes the mounting assembly 42 to move. The mounting assembly 42 drives the mounting tool holder 6 to approach the tension roller 2. The printed product is clamped between the exhaust cutter head 8 and the tension roller 2. Then, the belt is sleeved between the driving gear 53 and the driven gear 54, and the belt is tightened so that the belt can realize the transmission between the driving gear 53 and the driven gear 54.

[0061] When producing a printed product with exhaust holes, the tension roller 2 rotates, and the paper moves between the tension roller 2 and the mounting tool holder 6. The driving motor 51 is started. The driving motor 51 drives the driving shaft 52 to rotate. The driving shaft 52 drives the driving gear 53 to rotate. The driving gear 53 drives the driven gear 54 to rotate through the belt. The driving gear 53 drives the rotating shaft 422 to rotate. The mounting tool holder 6 arranged on the rotating shaft 422 rotates synchronously. The exhaust cutter head 8 on the mounting tool holder 6 rotates accordingly. The exhaust cutter head 8 contacts the printed product. When the exhaust cutter head 8 rotates, the punching tip 81 of the exhaust hole passes through the printed product and is fitted in the exhaust hole punching tip receiving groove 22. At the same time, continuous exhaust holes are machined on the surface of the printed product.

[0062] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
