Description

Technical Field

[0001] The invention relates to an automatic extruder for bagged ink. Background Art

[0002] Ink is a commonly used production raw material, often used in printing equipment. At present, the ink on the market is usually packaged in iron barrels, which has high packaging costs and heavy weight. It is also easy to rust and cause ink pollution, which brings inconvenience to use. Bag-packed ink in packaging bags is an emerging packaging technology, which effectively reduces costs and weight, and can also provide good protection for ink. However, since the ink bag is usually soft, it brings certain difficulties to the use of the ink bag on the corresponding equipment. At present, the ink bag is usually directly hung up, and the ink outlet at the lower end of the ink bag is connected to the ink inlet of the corresponding equipment. Then, only the dead weight of the ink is used to make the ink flow naturally into the equipment. However, since the ink is usually thick, it is often difficult to flow out quickly and completely naturally, and it is often difficult to adapt to the production needs of the corresponding equipment. At the same time, it will also cause too much ink to remain in the packaging bag and cannot flow out naturally, which is relatively wasteful. The packaging bag with residual ink is also very harmful when it is recycled and easily pollutes the environment. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Figure 1 It is a schematic diagram of the structure of the present invention;

[0021] Figure 2 yes Figure 1 A partial enlarged view of part A. DETAILED DESCRIPTION

[0022] Reference Figure 1 and Figure 2 , an automatic extruder for bagged ink, comprising: a base 10; a clamping roller assembly, comprising a first clamping roller 111 and a second clamping roller 112, both of which are rotatably arranged on the base 10, and the first clamping roller 111 and the second clamping roller 112 can clamp the ink bag 31; a driving device 12, arranged on the base 10, for driving the first clamping roller 111 and / or the second clamping roller 112 to rotate so that the clamping roller assembly can move along the ink bag 31 to squeeze the ink out of the ink bag 31. In the present invention, the first clamping roller 111 and the second clamping roller 112 can clamp the ink bag 31, and can rotate and move along the ink bag 31 under the drive of the driving device 12, thereby the ink can be squeezed out quickly and fully, can meet the production requirements of the corresponding equipment, and can effectively reduce the ink residue and waste, and also facilitate the recycling of the ink bag 31, which can effectively reduce the pollution to the environment, and has a simple structure and is easy to use.

[0023] In this embodiment, the driving device 12 uses a motor and a belt transmission mechanism, the first clamping roller 111 is an active roller driven by the driving device 12, and the second clamping roller 112 is a driven roller. Of course, in actual applications, the driving device 12 can also directly use a servo motor or a gear transmission mechanism driven by a motor, a chain transmission mechanism driven by a motor, and other commonly used driving structures, and is not limited to this.

[0024] In this embodiment, when in use, the base 10 is hung on the ink bag through the clamping roller assembly. When the clamping roller assembly moves down along the ink bag 31 to extrude the ink, the extruder moves down accordingly. The structure is simple and easy to install and use. Of course, in practical applications, the base 10 can also be fixed on the corresponding equipment. A lifting seat that can move up and down can be set on the base 10, and the clamping roller assembly is set on the lifting seat, so that the position of the base 10 relative to the equipment remains unchanged when the clamping roller assembly moves up and down.

[0025] A heating device 13 is provided on the base 10, and the heating device 13 is used to heat the ink bag 31, thereby heating the ink during use so that the ink can reach the temperature required for the production of the corresponding equipment, which effectively facilitates the use and can also make the outflow of the ink smoother, and is intended to increase the ink outflow speed and reduce residue. The heating device 13 is located in the first clamping roller 111 and / or the second clamping roller 112, so that heat transfer can be carried out by using the first clamping roller 111 and / or the second clamping roller 112, the structure is simpler, and the heat conduction is more uniform. In this embodiment, the heating device 13 is an electric heating tube arranged in the first clamping roller 111 and the second clamping roller 112. Of course, in actual applications, the heating device 13 can also be arranged only in the first clamping roller 111 or the second clamping roller 112. The heating device 13 can also adopt other commonly used heating structures such as electric heating wires, electric heating plates, infrared lamps, etc. The heating device 13 can also be installed outside the first clamping roller 111 and the second clamping roller 112, and the ink bag 31 is heated by heat radiation or heat transfer with the ink bag 31, but it is not limited to this.

[0026] In the present invention, the second clamping roller 112 is movably arranged on the base 10, and an elastic device 14 is arranged between the second clamping roller 112 and the base 10, and the elastic device 14 is used to push the second clamping roller 112 to move relative to the base 10 so that the second clamping roller 112 can clamp the ink bag 31 together with the first clamping roller 111, so that the elastic force of the elastic device 14 can be used to enable the first clamping roller 111 and the second clamping roller 112 to elastically clamp the ink bag 31, ensuring that the ink bag 31 is subjected to appropriate force, avoiding excessive clamping force causing the ink bag 31 to be damaged and loosened or excessive clamping force causing excessive ink residue, reducing the incidence of accidents, ensuring the normal use of the present invention, and being able to conveniently apply ink bags 31 of different specifications and thicknesses. At the same time, it is also convenient to clamp the upper part of the ink bag 31 between the first clamping roller 111 and the second clamping roller 112, so as to facilitate the loading operation. In this embodiment, the first clamping roller 111 is located in front of the second clamping roller 112, and the elastic device 14 adopts a spring and a push block structure. The spring drives the push block to abut against the second clamping roller 112, thereby pushing the second clamping roller 112 to move forward to clamp the ink bag 31 together with the first clamping roller 111. The structure is simple and easy to install and use. Of course, in actual applications, the elastic device 14 can also adopt other commonly used elastic structures such as elastic drawstrings and gas springs, and the second clamping roller 112 can also be located at other suitable positions such as below, above, obliquely above, obliquely below, etc., of the first clamping roller 111, and is not limited thereto.

[0027] In the present invention, an adjusting device 141 is provided on the base 10, and the adjusting device 141 is used to adjust the thrust of the elastic device 14 on the second clamping roller 112, so that the clamping force of the first clamping roller 111 and the second clamping roller 112 on the ink bag 31 can be conveniently adjusted as needed, so that the clamping roller assembly can fully squeeze out the ink while not causing the ink bag 31 to be damaged or loosened due to excessive force. In this embodiment, the adjusting device 141 uses an adjusting screw, which abuts against the spring. The position of the rear end of the spring is changed by screwing in or out of the adjusting screw, thereby adjusting the elastic force applied by the spring to the second clamping roller 112. The structure is simple and easy to install and use. Of course, in actual applications, the adjusting device 141 can also use other common structures such as a latch structure that can abut against the spring, and is not limited to this.

[0028] The base 10 is provided with a manual control member 15 connected to the first clamping roller 111 or the second clamping roller 112. The manual control member 15 can drive the first clamping roller 111 or the second clamping roller 112 to rotate so that the clamping roller assembly moves along the ink bag 31. In this way, when the ink bag 31 is installed on the extruder, a small part of the tail end of the ink bag 31 can be clamped between the first clamping roller 111 and the second clamping roller 112. Then, the manual control member 15 is used to drive the clamping roller assembly to move quickly relative to the ink bag 31 so that the clamping roller assembly quickly reaches a predetermined position. When the ink bag 31 needs to be removed, the ink bag 31 can also be quickly removed from the extruder by the manual control member 15, which can effectively facilitate the disassembly and replacement of the ink bag 31, help improve production efficiency, and facilitate use. In this embodiment, the manual control member 15 uses a hand wheel connected to the second clamping roller 112, which has a simple structure and is easy to operate and use. Of course, in actual applications, the manual control member 15 can also use other commonly used operating structures such as a turning handle, but is not limited to this.

[0029] A controller and a first detection device 161 for detecting the expansion degree of the ink bag 31 are provided on the base 10. The controller can control the start and stop and / or power of the drive device 12 according to the detection result of the first detection device 161. In this way, when the movement speed of the clamping roller assembly is too fast or the ink output speed is too slow, causing the ink bag 31 to expand excessively, the controller can turn off the drive device 12 to stop squeezing or reduce the power of the drive device 12 according to the detection structure of the first detection device 161, so as to slow down the movement speed of the clamping roller assembly to prevent the ink bag 31 from being broken or loosened from the corresponding equipment due to excessive force. When the ink recovers to the normal expansion degree, the controller controls the drive device 12 to start or increase the power of the drive device 12 to a predetermined value. When the ink bag 31 shrinks too much, that is, the speed of the clamping roller assembly is too slow or the ink output speed cannot keep up with the speed at which the equipment consumes ink, the controller can also increase the power of the drive device 12.

[0030] A second detection device 162 for detecting the position of the base 10 or the clamping roller assembly relative to the ink bag 31 is provided on the base 10. The controller can control the start and stop and / or the power of the driving device 12 according to the detection result of the second detection device 162. The second detection device 162 is usually used to detect whether the base 10 or the clamping roller assembly has reached or is about to reach the bottom of the ink bag 31, thereby automatically and timely slowing down the movement of the clamping roller assembly or shutting down the clamping roller assembly to prevent the clamping roller assembly and the base 10 from falling off the ink bag 31 and preventing accidents.

[0031] In the present invention, the power of the driving device 12 can be set by the controller, thereby setting the speed at which the clamping roller assembly moves along the ink bag 31, thereby setting the extrusion speed of the ink, which has wider applicability and is easy to use.

[0032] The controller, the first detection device 161 and the second detection device 162 are widely used in this field. The controller can usually adopt common data processing and control structures such as circuit boards and control chips. The first detection device 161 and the second detection device 162 can adopt common detection structures such as ultrasonic detectors and infrared detectors, or the first detection device 161 can also be used to simultaneously realize the function of the second detection device 162, so there is no need to set up the second detection device 162 separately. These are all common technical means in this field. Those skilled in the art can flexibly design and select them according to their needs, which will not be described in detail here.

[0033] In this embodiment, the base 10 is also provided with a temperature regulating switch 171, a start switch 172 and a speed regulating switch 173, all of which are connected to the controller. The temperature regulating switch 171 can be used to set the heating temperature of the heating device 13 through the controller, and a temperature detector can be correspondingly provided on the base 10 to detect the temperature of the ink bag 31, so as to accurately control the temperature of the ink bag 31 and make it more flexible and convenient to use; the pneumatic switch is used to control the start and stop of the present invention; the speed regulating switch 173 can set the moving speed of the clamping roller assembly relative to the ink bag 31 through the controller to set the extrusion speed of the ink, so as to facilitate use and have a wider range of applications. These switches and corresponding controllers are widely used in this field, and the structures and principles are well known to those skilled in the art, and will not be described in detail here.

[0034] The present invention also includes a hanging seat, which has a clamping device for clamping the ink bag 31. The hanging seat is provided with a hook 24. The user can use the clamping device to clamp the hanging seat on the ink bag 31. Then, the hook 24 can be used to conveniently hang the ink bag 31 on the corresponding bracket 32, which is convenient to use. There is no need to set a hanging structure such as a hanging ring on the ink bag 31, which can simplify the structure of the ink bag 31 and reduce the cost of the ink bag 31. It also enables the present invention to adapt to ink bags 31 of different sizes and specifications, and has a wider range of applications. In this embodiment, the clamping device includes two clamping plates 21, which are driven by a driver and can move relative to each other to clamp the tail of the ink bag 31 or release the ink bag 31. The hanging seat is provided with a control button 23 for controlling the opening and closing of the clamping device, which is convenient to use. In this embodiment, the driver adopts a micro cylinder 22, which has a simple structure, a small size, a light weight, and is easy to install and use. Of course, in actual applications, the driver can also adopt other commonly used driving structures such as motors, and is not limited to this.

[0035] In this embodiment, the suspension seat is separated from the base 10. Of course, in practical applications, the suspension seat can also be set on the base 10, and correspondingly, the clamping roller assembly only needs to be set on the base 10 so that it can move up and down.

[0036] In this embodiment, the base 10 is box-shaped, and the clamping roller assembly and the heating device 13 are both arranged inside the base 10, which can play a good protective role and has a more regular and beautiful appearance. Of course, in actual applications, the base 10 can also adopt other suitable shapes such as a platform, and is not limited to this.

[0037] The above description is only a preferred implementation mode of the present invention. Any technical solution that achieves the purpose of the present invention by substantially the same means belongs to the protection scope of the present invention.
