Description

Technical Field

[0001] This utility model mainly relates to the field of paper bag processing technology, specifically an adjustable base for paper bag processing. Background Technology

[0002] In the paper bag processing industry, offset printing machines are the core equipment for printing graphics on the surface of paper bags, and the levelness of their base directly affects printing accuracy and product quality. When the offset printing machine is running, the contact pressure between the printing roller and the paper bag, as well as the stability of the conveying path, all depend on the levelness of the base. If the base is tilted, it will cause uneven axial pressure distribution on the printing roller, resulting in defects such as blurred graphics, misregistration, and localized indentations.

[0003] Currently, the leveling of offset printing machine bases mainly relies on manual operation. Operators need to hold a level and repeatedly place and read the level at multiple key points on the bottom of the base (such as the four corners, the middle, and the corresponding position of the printing cylinder). By comparing the level data at different points, they can determine whether the base is flat. The space at the bottom of the offset printing machine base is often narrow (some areas are less than 30cm high) and may be blocked by equipment supports and pipelines. When placing the level manually, operators need to bend over, turn sideways, and may even need to disassemble some protective parts. A single inspection takes more than 15 minutes. For large offset printing machines (base length ≥ 2m), there are even more points to be inspected, which further prolongs the operation time and seriously affects the efficiency of changeover adjustments or maintenance.

[0004] Meanwhile, during the operation of the offset printing machine, the horizontal state of the base may gradually change over time due to factors such as ground subsidence, mechanical vibration, and loose bolts. However, existing technology cannot monitor this dynamic shift in real time, and it is often only passively discovered after a large number of printing defects have occurred, resulting in the scrapping of batches of products. Utility Model Content

[0005] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. It mainly provides an adjustable base for paper bag processing to solve the technical problems mentioned in the background.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: An adjustable base for paper bag processing includes a mounting groove that moves within a recess at the bottom of the base. A screw mechanism is rotatably mounted inside the mounting groove, which drives a mounting block inside the mounting groove to move. The mounting block is connected to mounting plates fixedly mounted on both sides of an electronic level by bolts. Lifting feet are symmetrically mounted at the bottom of the mounting groove. A cavity is formed at the center of the top of the mounting groove, and a dual-axis level sensor is located at the center of the cavity.

[0007] Preferably, one side of the base is provided with an electric push rod that is driven to move through a mounting slot.

[0008] Preferably, a fixing strip is detachably installed on the outer side of the bottom end of the base, and a flexible dustproof net is provided below the fixing strip.

[0009] Preferably, one end of the mounting slot is provided with a lead screw motor for driving the lead screw mechanism to rotate.

[0010] Preferably, the lifting outrigger includes a hydraulic rod, which is installed inside the support cylinder. The hydraulic rod can drive a mounting plate that is slidably disposed inside the support cylinder to move, and the top of the mounting plate is connected to the bottom of the base through a support column.

[0011] Preferably, a liquid crystal display controller is installed on one side of the base, and the liquid crystal display controller is electrically connected to each electronic device.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) The installation slot is moved by the electric push rod and the installation block is moved by the screw mechanism, which drives the electronic level to automatically detect the levelness at multiple key points on the base. This replaces the manual operation of bending over and turning sideways to repeatedly place the level, reducing the time spent on each test and thus improving the efficiency of production change adjustment or maintenance of the offset printing machine.

[0013] (2) By using the dual-axis horizontal sensor in the cavity to monitor the overall dual-axis horizontal angle of the base in real time, the horizontal deviation caused by ground settlement, mechanical vibration and other factors during operation can be dynamically captured, thereby avoiding the passive discovery of problems after a large number of printing defects occur, and reducing the scrapping of batch products.

[0020] Please refer to the appendix carefully. Figure 1-4 An adjustable base for paper bag processing, wherein the mounting groove 1 moves within a groove at the bottom of the base 2, and an electric push rod 9 is provided on one side of the base 2 to drive the mounting groove 1 to move. A dust cover can be provided on the outside of the electric push rod 9 to reduce the impact of dust on the later operation of the electric push rod 9. A convex slider is provided on the top of the mounting groove 1, and a sliding groove matching the slider is provided on the base 2. A screw mechanism 3 is rotatably provided inside the mounting groove 1, and a screw motor is provided at one end of the mounting groove 1 to drive the screw mechanism 3 to rotate. The screw mechanism 3 can drive the mounting block 4 provided inside the mounting groove 1 to move. The mounting block 4 is connected to the mounting plates fixed on both sides of the electronic level 5 by bolts. Two positioning pins are added to the mounting plate of the mounting block (4), and matching positioning holes are opened at the positions of the mounting plates of the electronic level 5. During installation, the positioning pins are inserted into the positioning holes to achieve quick calibration and ensure consistent installation angles. The model of the electronic level 5 is Aoruit AR-852. The electronic level 5 can be separated from the mounting block 4 after the test is completed.

[0021] A cavity 7 is provided at the center of the top of the mounting slot 1, and a dual-axis level sensor 8 is provided at the center of the cavity 7. A dustproof heat dissipation vent is provided on the cavity 7. The dual-axis level sensor 8 can be a Beiwei Sensing BWS2000. Its function is to measure the levelness of the carrier. It is also called an inclination sensor. The dual-axis level sensor 8 can measure the horizontal angle in two directions at the same time, so the levelness of the entire measured surface can be determined.

[0022] The bottom of the mounting slot 1 is symmetrically equipped with lifting feet 6. The lifting feet 6 include hydraulic rods 61, and the hydraulic rods 61 are installed inside the support cylinder 62. The support cylinder 62 is provided with heat dissipation vents and connection ports that cooperate with the hydraulic rods 61. The hydraulic rods 61 can drive the mounting plate that is slidably set inside the support cylinder 62 to move, and the top of the mounting plate is connected to the bottom of the base 2 through the support column 63.

[0023] A fixing strip 21 is detachably installed on the outer side of the bottom end of the base 2, and a flexible dustproof net 22 is provided below the fixing strip 21. The flexible dustproof net 22 can effectively block external dust, paper scraps, impurities and other contaminants from entering the interior of the base 2 and the bottom gaps, preventing these contaminants from adhering to the surface of precision components such as the lead screw mechanism 3, the hydraulic rod 61 of the lifting support leg 6, and the support column 63, preventing them from jamming, wearing or reducing accuracy due to contamination, and ensuring the stable operation of the adjustment function of the base 2.

[0024] A liquid crystal display controller 10 is installed on one side of the base 2. The liquid crystal display controller 10 is electrically connected to the dual-axis level sensor 8, electric push rod 9, lead screw motor, hydraulic rod 61 and electronic level 5. The liquid crystal display controller 10 can be equipped with a synchronous control component, which can facilitate the synchronous control of several sets of hydraulic rods 61 in the later stage.

[0025] The specific operating procedure of this utility is as follows: According to the installation environment requirements of the base 2, the hydraulic rod 61 is operated by the LCD display controller 10 to drive the mounting plate in the support cylinder 62 to rise and fall synchronously, thereby driving the support column 63 to adjust the overall height of the base 2 until the bottom of the base 2 maintains a reasonable distance from the ground. During the adjustment process, the LCD display controller 10 displays the height data of each support leg in real time.

[0026] After the initial height adjustment is completed, align the mounting plates on both sides of the electronic level 5 with the connection points of the mounting block 4 and tighten them with bolts to ensure that the electronic level 5 is installed firmly and without tilt. When the electronic level 5 moves with the mounting groove 1 (driven by the electric push rod 9) or adjusts its position with the screw mechanism 3, it detects the levelness data of different points on the base 2 in real time and transmits it to the LCD display controller 10. Based on the data from the electronic level 5, the LCD display controller 10 controls the hydraulic rod 61 of the corresponding lifting support leg 6 to move. If a certain area is too high, the hydraulic rod 61 retracts, causing the support column 63 to sink. If it is too low, the hydraulic rod 61 extends, pushing the support column 63 to rise. Repeated fine adjustments are made until the levelness of each detection point on the base 2 displayed by the electronic level 5 is within the qualified threshold.

[0027] After confirming that the level adjustment is qualified in the LCD display controller 10, turn off the detection function of the electronic level 5, remove the electronic level 5 from the mounting slot 1 and store it properly. After the base 2 is put into use, the dual-axis level sensor 8 will start automatically and continuously collect the overall X-axis and Y-axis tilt angle data of the base 2. The data will be transmitted to the LCD display controller 10 in real time. If the offset exceeds the preset threshold, the controller will automatically trigger an alarm screen flashing and a buzzer sounding, prompting the operator to readjust the level through the previous procedures.

[0028] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
