Description

Technical Field

[0001] This utility model relates to the field of paper box processing equipment technology, and more specifically, to a non-destructive demolding component for paper box forming equipment. Background Technology

[0002] Paper box forming equipment is an automated equipment used to process cardboard into various types of paper boxes. It is widely used in the packaging fields of food, medicine, and daily necessities. There are many types of paper box forming equipment on the market, which mainly include mechanical folding and mold forming.

[0003] Patent CN112428621B discloses a paper box forming device, comprising a feeding device, a folding device, and a sealing device arranged sequentially. The feeding device includes a transverse guide rail and several vacuum suction cups, which move along the transverse guide rail. The folding device includes a lowering inner punch, a folding outer mold, and a conveying device. The folding outer mold comprises a flared rectangle formed by a front baffle, side baffles, and a rear baffle, and corner stops at the outer corners of the rectangle. The conveying device delivers the paper box with the bottom box completed to the sealing device. The sealing device includes a paper box pushing mechanism, a support platform, bending guide rods, and an end-fitting mechanism. Two bending guide rods are symmetrically arranged on both sides of the support platform, with the inlet spacing and height of the bending guide rods gradually decreasing. The end-fitting mechanism is located above the support platform. This invention can automatically complete the bottom box forming of flat paper sheets and the sealing and bonding of the lid during the paper box pushing process, improving production efficiency.

[0004] While the aforementioned technical solutions have their advantages, most current cardboard box forming equipment also has some shortcomings. Since the cardboard box needs to be demolded after forming, traditional demolding methods often use mechanical pushing. Mechanical pushing is prone to uneven force, leading to deformation and wrinkles at the edges and corners of the cardboard box, especially for softer materials or coated surfaces, resulting in a higher damage rate. Therefore, we propose a non-destructive demolding component for cardboard box forming equipment. Utility Model Content

[0005] The purpose of this invention is to provide a non-destructive demolding component for a paper box forming equipment, so as to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The non-destructive demolding component of the paper box forming equipment includes a transverse electric slide and a longitudinal electric slide mounted on the slide base of the transverse electric slide. A top plate is fixedly installed on the slide base of the longitudinal electric slide, and a cylinder is fixedly installed on the bottom surface of the top plate. A vent plate is detachably installed at the end of the telescopic shaft of the cylinder. A vacuum pump is fixedly installed on the vent plate, and the vacuum pump is connected to the vent plate through a suction pipe. Multiple vertical pipes arranged in a matrix are fixedly installed at the bottom of the vent plate, and valves are fixedly installed on the vertical pipes. Vacuum suction cups are detachably installed on some of the vertical pipes, and sealing plugs are detachably installed on the remaining vertical pipes.

[0008] Preferably, it also includes a crossbeam plate, and the transverse electric slide is fixedly installed on the bottom surface of the crossbeam plate.

[0009] Preferably, two symmetrical fixed supports are fixedly installed on the upper surface of the crossbeam plate, and the fixed supports are fixedly installed on the external frame.

[0010] Preferably, a steel plate is fixedly installed at the end of the telescopic shaft of the cylinder, and the vent plate is detachably installed on the bottom surface of the steel plate.

[0011] Preferably, two symmetrical guide sleeves are fixedly installed on the upper surface of the vent plate, and two symmetrical guide posts are fixedly installed on the bottom surface of the top plate. The guide sleeves are fitted onto the guide posts and are slidably connected to the guide posts.

[0012] This setting guides the up-and-down movement of the vent plate.

[0013] Preferably, both the vacuum suction cup and the sealing plug are fixedly installed with threaded joints at their bottom ends, and the threaded joints are threadedly connected to the corresponding vertical pipes.

[0014] This setting facilitates the installation of vacuum suction cups and sealing plugs.

[0015] Preferably, the top of the threaded connector is integrally formed with a knob, and the knob has a hexagonal cross-section.

[0016] Preferably, the vacuum suction cup has a threaded tube inside its tube body, a gas channel is provided at the center of the threaded tube, a filter screen is fixedly installed on the inner wall of the gas channel, and a cross protrusion is fixedly installed on the hole wall of the air inlet of the gas channel.

[0017] This setting serves to filter the vacuum suction cup during adsorption, preventing impurities from entering the subsequent pipes with the air and causing blockages.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model uses a horizontal electric slide and a vertical electric slide to drive the vacuum suction cup to move, and works with a cylinder to achieve lifting. The vacuum pump uses a vent plate and a vertical pipe to make the vacuum suction cup generate suction to adsorb the cardboard box, replacing the traditional mechanical pushing, realizing flexible gripping of the cardboard box, solving the problem of uneven force on the cardboard box caused by mechanical pushing, and achieving the effect of reducing damage to the cardboard box.

[0020] 2. Based on the size and shape of the cardboard box, this utility model uses a sealing plug to block part of the vertical tube, adjusts the distribution position of the vacuum suction cup, and uses a guide sleeve and guide post to ensure smooth lifting. The valve controls the suction force, thus achieving adaptability to cardboard boxes of different specifications. This solves the problem of poor applicability of a single demolding structure and improves the versatility and operational stability of the components.

[0021] 3. This utility model filters impurities and prevents pipe blockage by setting a filter screen and cross protrusion inside the threaded tube of the vacuum suction cup. The threaded joint facilitates the disassembly and replacement of the suction cup, and the fixed support and crossbeam plate ensure the overall structural stability. Attached Figure Description

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.

[0031] Please see Figures 1-5 This utility model provides a technical solution: a non-destructive demolding component for a paper box forming equipment, including a transverse electric slide 11 and a longitudinal electric slide 12 mounted on the slide base of the transverse electric slide 11. A top plate 13 is fixedly mounted on the slide base of the longitudinal electric slide 12, and a cylinder 14 is fixedly mounted on the bottom surface of the top plate 13. A vent plate 15 is detachably mounted at the end of the telescopic shaft of the cylinder 14. A vacuum pump 19 is fixedly mounted on the vent plate 15, and the vacuum pump 19 is connected to the vent plate 15 through a suction pipe 191. Multiple vertical pipes arranged in a matrix are fixedly mounted at the bottom of the vent plate 15. 16. A valve 161 is fixedly installed on the vertical pipe 16. Vacuum suction cups 2 are detachably installed on some of the vertical pipes 16, and sealing plugs 20 are detachably installed on the remaining vertical pipes 16. The vacuum suction cups 2 are flexibly moved by the horizontal electric slide table 11 and the vertical electric slide table 12. The cylinder 14 drives the ventilation plate 15 to rise and fall. The vacuum pump 19 generates suction force on the vacuum suction cups 2 through the ventilation plate 15 and the vertical pipe 16. The suction force is adjusted in conjunction with the valve 161. The sealing plugs 20 are adapted to different cardboard box sizes, so that the demolding process is gentle and controllable, avoiding mechanical pushing damage and achieving the effect of non-destructive demolding.

[0032] like Figure 1 As shown, it also includes a crossbeam plate 1, and a transverse electric slide 11 is fixedly installed on the bottom surface of the crossbeam plate 1. The crossbeam plate 1 provides an installation base for the transverse electric slide 11.

[0033] like Figure 1 As shown, two symmetrical fixed supports 10 are fixedly installed on the upper surface of the crossbeam plate 1. The fixed supports 10 are fixedly installed on the external frame, so that the overall structure is not easy to shake during operation, ensuring the precise demolding position and achieving the effect of improving structural stability.

[0034] like Figure 1 As shown, a steel plate 141 is fixedly installed at the end of the telescopic shaft of the cylinder 14, and the vent plate 15 is detachably installed on the bottom surface of the steel plate 141 by multiple fastening bolts, which facilitates the fixing, installation and disassembly operations.

[0035] like Figure 1As shown, two symmetrical guide sleeves 17 are fixedly installed on the upper surface of the vent plate 15, and two symmetrical guide posts 18 are fixedly installed on the bottom surface of the top plate 13. The guide sleeves 17 are fitted on the guide posts 18 and are slidably connected to the guide posts 18, which guides the vent plate 15 to move up and down, avoids deviation that causes uneven force on the suction cup, makes the lifting process smooth and stable, and achieves the effect of improving the motion accuracy.

[0036] In this embodiment, threaded connectors 22 are fixedly installed at the bottom ends of both the vacuum suction cup 2 and the sealing plug 20. The threaded connectors 22 are threadedly connected to the corresponding vertical tubes 16, which facilitates loading and unloading operations. A knob 21 is integrally formed on the top of the threaded connector 22. The knob 21 has a hexagonal cross-section, which facilitates manual disassembly and assembly, making it easier to replace the vacuum suction cup 2 and the sealing plug 20 according to the cardboard box specifications, thereby improving operational flexibility.

[0037] Specifically, the vacuum suction cup 2 has a threaded tube 23 inside its tube body. A gas channel 231 is provided at the center of the threaded tube 23. A filter screen 25 is fixedly installed on the inner wall of the gas channel 231. A cross protrusion 24 is fixedly installed on the hole wall of the air inlet of the gas channel 231. The filter screen 25 filters air impurities, and the cross protrusion 24 supports the filter screen without affecting the airflow, preventing pipe blockage, extending the service life of the vacuum pump 19 and the pipeline, and achieving the effect of ensuring the continuous and stable operation of the equipment.

[0038] Finally, it should be noted that the transverse electric slide 11, longitudinal electric slide 12, cylinder 14, vacuum pump 19, corresponding control system, and external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.

The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0039] When using the non-destructive demolding component of the paper box forming equipment of this utility model, according to the size of the paper box, the threaded joint 22 is rotated by the knob 21 to install an appropriate number of vacuum suction cups 2 on the vertical tube 16, and the rest are sealed with sealing plugs 20. The suction force is set by adjusting the valve 161; the crossbeam plate 1 is installed on the external frame through the fixed support 10 to ensure the stability of the horizontal electric slide table 11.

[0040] When the equipment is started, the horizontal electric slide 11 and the vertical electric slide 12 drive the cylinder 14 and the vacuum suction cup 2 to move above the paper box. The cylinder 14 pushes the ventilation plate 15 down, the guide sleeve 17 slides along the guide post 18, and the vacuum pump 19 uses the suction pipe 191, the ventilation plate 15 and the vertical pipe 16 to make the vacuum suction cup 2 adsorb the paper box. The cross protrusion 24 and the filter screen 25 filter impurities.

[0041] After adsorption, cylinder 14 contracts, causing the paper box to rise and complete demolding. The electric slide moves to the placement position, and vacuum pump 19 is turned off to release the paper box.
