Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a bagged ink extrusion device for a printing press. Background Technology

[0002] In the printing industry, precise ink supply is a core element in ensuring printing quality and production efficiency. Bagged inks, due to their advantages such as ease of transport, good sealing, and reduced pollution, are gradually replacing traditional canned inks as the mainstream packaging form. To accommodate the refilling needs of bagged inks, modern printing equipment typically incorporates a dedicated extrusion device at the ink filling port. This device uses mechanical pressure to evenly extrude ink from the soft bag into the ink reservoir or ink supply system. However, traditional extrusion devices, due to structural limitations, can only extrude ink from a single bag independently. After one bag of ink is extruded, the operator needs to place the next bag on the device for extrusion. Due to device size limitations, regardless of whether the ink is in large or small bags, the process of changing bags one by one must be followed, significantly reducing the extrusion efficiency and adaptability of the extrusion device. Therefore, there is an urgent need for a bagged ink extrusion device that can achieve continuous extrusion of multiple bags, greatly improving the extrusion efficiency and adaptability of printing equipment extrusion devices. Utility Model Content

[0003] The purpose of this invention is to provide a bagged ink extrusion device for printing presses, which solves the problems of low extrusion effect and poor adaptability to bagged inks in traditional extrusion devices.

[0004] The present invention provides the following technical solution: a bagged ink extrusion device for a printing press, comprising an ink feeding device on the printing press and an ink extrusion device corresponding to the ink feeding device. The ink extrusion device includes an ink extrusion chamber, a bag winding mechanism, and a bag clamping mechanism. The ink feeding chamber has a winding cavity inside, and the bottom of the winding cavity extends along the length direction with an extrusion port. The bag winding mechanism includes a roller rotatably disposed in the winding cavity and a winding driver for driving the roller to rotate. The roller is detachably connected to multiple bag clamping mechanisms. The bag clamping mechanisms are used to clamp the edge of the ink bag and are installed on the roller so that the ink bag is engaged with the extrusion port. The ink feeding device has an ink inlet groove facing the extrusion port. The winding driver drives the roller to rotate to drive the ink bag to be wound into the winding cavity. The extrusion port is used to continuously extrude ink from both sides of the ink bag so that the ink inlet groove can continuously receive the ink extruded from the ink bag.

[0005] As described above, a bagged ink extrusion device for a printing press includes a bag clamping mechanism comprising a pair of opposing clamping plates. The upper edges of the clamping plates are hinged together along their length. A plurality of corresponding piercing heads and piercing holes are arranged on the clamping plates along their length. The opposing clamping plates can approach each other and clamp the edge of the ink bag. The piercing heads pierce the ink bag and extend into the piercing holes to fix the ink bag.

[0006] As described above, in a bag-type ink extrusion device for a printing press, the clamping plates are provided with flanges along the length direction on opposite sides, so that the cross-section of the bag clamping mechanism is cross-shaped when clamped. The roll is provided with a cross-shaped insertion groove along the length direction, and a disassembly port is provided on one side of the winding cavity. The bag clamping mechanism can be installed or removed from the insertion groove through the disassembly port.

[0007] As described above, in a bagged ink extrusion device for a printing press, each of the clamping plates has a crease pressing surface on its opposite side. When the bag clamping mechanism clamps the ink bag, the crease pressing surfaces are pressed against both sides of the ink bag.

[0008] As described above, in a bagged ink extrusion device for a printing press, the ink extrusion chamber is provided with a protective cover that is oscillating and corresponds to the disassembly port. When the bag clamping mechanism is installed in the insertion slot, the protective cover is used to cover the disassembly port to prevent the bag clamping mechanism from disengaging from the insertion slot.

[0009] As described above, in a bagged ink extrusion device for a printing press, the cover has a support opening, and when the cover is closed to the disassembly opening, the roll passes through the support opening.

[0010] As described above, in a bagged ink extrusion device for a printing press, a hook is provided on the side of the cover away from the hinge, and a latch is provided on the ink extrusion chamber. When the cover is closed to the disassembly port, the latch is used to lock the cover.

[0011] As described above, a bagged ink extrusion device for a printing press further includes a translation mechanism, which includes a moving platform and a translation driver. The translation driver drives the moving platform to move back and forth along the length of the ink inlet groove, and the extrusion chamber is located on the lower side of the moving platform.

[0012] As described above, in a bag ink extrusion device for a printing press, the translation mechanism further includes brackets disposed opposite to both ends of the ink inlet trough and a transmission screw passing through the brackets. The moving platform is provided with threaded holes along its length for the transmission screw to pass through. The output end of the translation driver is connected to the transmission screw to drive the moving platform to move back and forth between the brackets.

[0013] As described above, in a bagged ink extrusion device for a printing press, the moving platform is provided with buffer blocks on both sides opposite the support.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] This utility model discloses a bagged ink extrusion device for a printing press. It adds an ink extrusion device to the printing press, corresponding to the ink feeding device. The extrusion device includes an ink extrusion chamber and employs a bag-rolling mechanism and a bag-clamping mechanism in cooperation within the ink extrusion chamber to achieve efficient extrusion of bagged ink. The bag-rolling mechanism includes a roller that can rotate within a winding chamber in the ink extrusion chamber. The bag-clamping mechanism is used to fix the edge of the ink bag. The bag-clamping mechanism is then installed on the roller, causing the ink bag to be clamped to the extrusion port. The rotation of the roller causes the ink bag to be rolled up. During the rolling process, the extrusion port continuously squeezes the ink bag, causing ink to be continuously extruded from the bag's opening. The roller can be detachably connected to multiple bag-clamping mechanisms. For small ink bags, a one-bag-one-clamp configuration can be used, allowing the roller to extrude ink from multiple ink bags simultaneously. For large ink bags, a one-bag-multiple-clamp configuration can be used, achieving efficient ink extrusion and significantly improving the extrusion effect and adaptability of the extrusion device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to the appendix Figure 1 To be continued Figure 4 This embodiment provides a bagged ink extrusion device for a printing press, including an ink feeding device 1 and an ink extrusion device 2 corresponding to the ink feeding device 1. The ink extrusion device 2 includes an ink extrusion chamber 21, a bag winding mechanism 22, and a bag clamping mechanism 23. The ink extrusion chamber 21 has a winding cavity 211 inside, and the bottom of the winding cavity 211 extends along the length direction with an extrusion port 212. The bag winding mechanism 22 includes a roller 221 rotatably disposed in the winding cavity 211, and a mechanism for driving the roller 221 to rotate. The winding driver 222 and the reel 221 are detachably connected to multiple bag clamping mechanisms 23. The bag clamping mechanism 23 is used to clamp the edge of the ink bag and is installed on the reel 221 so that the ink bag is clamped in the extrusion port 212. The ink feeding device 1 is provided with an ink feeding groove 11 facing the extrusion port 212. The winding driver 222 drives the reel 221 to rotate so as to drive the ink bag to be wound into the winding chamber 211. The extrusion port 212 is used to continuously squeeze both sides of the ink bag so that the ink feeding groove 11 can continuously receive the ink squeezed out from the ink bag. The bagged ink extrusion device for a printing press in this embodiment adds an ink extrusion device 2 to the printing press, corresponding to the ink feeding device 1. The ink extrusion device 2 includes an ink extrusion chamber 21, and uses a bag rolling mechanism 22 and a bag clamping mechanism 23 in cooperation within the ink extrusion chamber 21 to achieve efficient extrusion of the bagged ink. The bag rolling mechanism 22 includes a roller 221 that can rotate in a winding cavity 211 within the ink extrusion chamber 21. The bag clamping mechanism 23 is used to fix the edge of the ink bag. The bag clamping mechanism 23 is then installed onto the roller 221 so that the ink bag is clamped to the extrusion port 21. 2. Then, the rotation of the roller 221 will cause the ink bag to be wound up. During the winding process, the extrusion port 212 will continuously squeeze the ink bag, so that the ink will be continuously squeezed out at the opening of the bag. The roller 221 can be detachably connected to multiple bag clamping mechanisms 23. For small ink bags, one bag can be paired with one clamp, so that the roller 221 can squeeze ink from multiple ink bags at the same time. For large ink bags, one bag can be paired with multiple clamps, which can also achieve a highly efficient ink extrusion effect and greatly improve the extrusion effect and adaptability of the extrusion device.

[0023] The bag clamping mechanism 23 includes a pair of opposing clamping plates 231. The upper edges of the clamping plates 231 are hinged together along their length. Multiple corresponding piercing heads 232 and piercing holes 233 are arranged on the clamping plates 231 along their length. The opposing clamping plates 231 can approach each other and clamp the edge of the ink bag. The piercing heads 232 pierce the ink bag and extend into the piercing holes 233 to secure the ink bag. This structure allows for quick securing or disassembly of the ink bag by the clamping plates 231. Furthermore, after winding, the ink bag is completely wound into the winding chamber 211. Even while the roll 221 is still rotating, the ink will not splash outside the winding chamber 211, maintaining a clean operating environment.

[0024] The clamping plate 231 has flanges 234 protruding along its length on both opposite sides, making the cross-section of the bag clamping mechanism 23 cross-shaped when clamped. The roller 221 has cross-shaped insertion grooves 223 along its length, and the winding cavity 211 has a disassembly port 213 on one side. The bag clamping mechanism 23 can be installed or removed from the insertion grooves 223 through the disassembly port 213. The cross-shaped mating structure effectively transmits the torque generated when the roller 221 rotates to the bag clamping mechanism 23 and prevents the bag clamping mechanism 23 from radially disengaging from the roller 221 when it rotates.

[0025] The clamping plate 231 has crease pressing surfaces 235 on both sides. When the bag clamping mechanism 23 clamps the ink bag, the crease pressing surfaces 235 press against both sides of the ink bag. The use of crease pressing surfaces 235 makes the clamping mechanism 23 clamp and fix the ink bag more firmly.

[0026] The ink extrusion chamber 21 is equipped with a protective cover 214 that is oscillating and corresponds to the disassembly port 213. When the bag clamping mechanism 23 is installed in the insertion slot 223, the protective cover 214 is used to cover the disassembly port 213 to prevent the bag clamping mechanism 23 from disengaging from the insertion slot 223.

[0027] The cover 214 has a support opening 2141. When the cover 214 is closed to the disassembly opening 213, the roller 221 passes through the support opening 2141. At this time, the cover 214 prevents the bag clamping mechanism 23 from disengaging from the insertion groove 223 by blocking the end of the ink bag at the extrusion opening 212.

[0028] A hook 2142 is provided on the side of the cover 214 away from the hinge, and a latch 215 is provided on the ink extrusion chamber 21. When the cover 214 is closed to the disassembly port 213, the latch 215 is used to lock the cover 214 to prevent the cover 214 from being accidentally opened during the operation of the device, thereby improving the safety of the device during operation.

[0029] The ink extrusion device 2 also includes a translation mechanism 24, which includes a moving platform 241 and a translation driver 242. The translation driver 242 drives the moving platform 241 to move back and forth along the length of the ink inlet trough 11. The ink extrusion chamber 21 is located on the lower side of the moving platform 241. The translation mechanism 24 can drive the ink extrusion chamber 21 to move back and forth along the ink inlet trough 11 so that the area of ​​ink extrusion can be distributed throughout the ink inlet trough 11.

[0030] The translation mechanism 24 also includes brackets 243 disposed opposite to both ends of the ink inlet trough 11, and a transmission screw 244 passing through the brackets 243. The moving platform 241 is provided with a threaded hole 2411 along its length for the transmission screw 244 to pass through. The output end of the translation driver 242 is connected to the transmission screw 244 to drive the moving platform 241 to move back and forth between the brackets 243. The use of screw transmission makes the back and forth movement of the moving platform 241 more stable.

[0031] The moving platform 241 is provided with buffer blocks 2412 on both sides facing the support 243. When the moving platform 241 moves close to and contacts the support 243, the buffer blocks 2412 can play a certain buffering role between the moving platform 241 and the support 243, protecting the ink extrusion device 2.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
