Description

Technical Field

[0001] This utility model belongs to the technical field of angle shaping machine, and in particular relates to a paper corner protector angle shaping machine. Background Technology

[0002] Paper corner protectors are L-shaped, U-shaped, and other corner-shaped packaging materials made of multiple layers of kraft paper or recycled paper. They are mainly used to reinforce and protect the edges and corners of products. They are environmentally friendly, lightweight, and pressure-resistant. The production of paper corner protectors requires the use of an angle shaping machine, which uses processes such as heating, pressurizing, and mold forming to precisely shape the glued paper strip into a set angle (such as 90° or 45°). They are widely used in the field of edge and corner protection in the packaging industry.

[0003] In the production process of paper corner protectors, there is a certain error in the angle formed by the cardboard. When the error value is too large, it will affect the product quality. At the same time, the angle formed by the cardboard is also different according to different product requirements. In the existing technology, multiple processing molds are required to produce paper corner protectors with different angle values, which increases the processing cost.

[0004] The existing patent (application number: CN202221719695.5) discloses a paper corner protector angle shaping machine. By setting a lower support plate and an upper pressure plate, the paper corner protector in the shaping space is squeezed by the lower support plate and the upper pressure plate under the action of the driving device. This allows the paper corner protector to deform according to the shape of the lower support plate and the upper pressure plate, reducing the angle error of the paper corner protector and ensuring product quality. Moreover, this shaping machine can also adjust the angle of the paper corner protector. It can produce paper corner protectors with different angle values ​​without setting different processing molds, thus reducing processing costs.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, in actual use, during the pressing and shaping process of multiple stacked paper corner protectors, the uneven pressure distribution caused by the stacked paper corner protectors during the downward pressing of the upper pressure plate may generate lateral forces, resulting in the paper corner protectors shifting and affecting the shaping effect. Therefore, improvements are needed. To this end, a paper corner protector angle shaping machine is proposed. Utility Model Content

[0030] 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 some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-6 This utility model provides a technical solution:

[0032] A paper corner protector angle setting machine includes a base 1, on which symmetrical vertical plates 2 are fixedly installed. A top plate 3 is fixedly installed on the top of the two sets of vertical plates 2. Electric telescopic columns 4 are evenly distributed and fixedly installed on the top plate 3. An installation plate 5 is fixedly installed on the output shaft end of the electric telescopic columns 4. An upper pressure plate 6 is fixedly installed on the bottom surface of the installation plate 5. A horizontal plate 7 is fixedly installed between the two sets of vertical plates 2. A lower support plate 8 is fixedly installed on the horizontal plate 7. The size of the lower support plate 8 is adapted to the size of the upper pressure plate 6, and the lower support plate 8 is directly opposite the upper pressure plate 6. Symmetrical slide rails 9 are opened on both sides of the horizontal plate 7 located on the lower support plate 8. A baffle 10 is slidably arranged on each slide rail 9. A connecting plate 11 is fixedly installed at the end of the baffle 10. An electric push rod 12 is fixedly installed on the bottom surface of the horizontal plate 7. The output shaft end of the electric push rod 12 is fixedly installed to the side of the connecting plate 11.

[0033] When in use, the base 1, the vertical plate 2, and the top plate 3 support the entire device;

[0034] When shaping multiple sets of paper corner protectors simultaneously, the operator places the stacked paper corner protectors on the lower support plate 8 of the horizontal plate 7, and then activates the electric push rod 12 on the bottom of the horizontal plate 7. The output shaft of the electric push rod 12 pulls the connecting plate 11, causing the baffle 10 to slide on the slide rail 9. During the sliding process, the baffle 10 gradually conforms to the two sides of the stacked paper corner protectors, forming a limit on the two sides of the stacked paper corner protectors. Then, the electric telescopic column 4 on the top plate 3 is activated. The output shaft of the electric telescopic column 4 drives the mounting plate 5 and the upper pressure plate 6 to descend vertically. Since the size of the lower support plate 8 is compatible with the size of the upper pressure plate 6 and they are aligned, the descent of the upper pressure plate 6 cooperates with the lower support plate 8 to press and shape the angle of the paper corner protectors. During this process, the baffles 10 on both sides effectively resist the lateral force caused by uneven pressure, ensuring that the paper corner protectors remain stable when being pressed and shaped, avoiding displacement, thereby improving the shaping effect.

[0035] A horizontal bar 13 is fixedly installed on the side of the baffle 10. An electric push rod 14 is fixedly installed on the horizontal bar 13. A push bar 15 is fixedly installed at the end of the output shaft of the electric push rod 14.

[0036] After the paper corner protector has been shaped, the upper pressure plate 6 is driven to move vertically upward slightly away from the paper corner protector, and the electric push rod 14 on the horizontal bar 13 is activated. The output shaft of the electric push rod 14 pushes the push bar 15, which in turn pushes the stacked paper corner protectors to move horizontally on the lower support plate 8, so that the ends of the paper corner protectors are removed from the lower support plate 8, making it easier to unload and arrange the paper corner protectors.

[0037] Push plates 16 are fixedly installed at both ends of push bar 15. The shape and size of the two sets of push plates 16 are adapted to the size of upper pressure plate 6 and lower support plate 8, respectively.

[0038] The push plates 16 installed at both ends of the push bar 15 are adapted to the size of the upper pressure plate 6 and the lower support plate 8 respectively. When the electric push rod 14 drives the push bar 15 to push the paper corner protector, the push plate 16 can contact the top and bottom paper corner protectors over a large area, so that the pushing force is evenly distributed on the paper corner protector, further improving the reliability of the feeding process.

[0039] The upper pressure plate 6 and its surface are both covered with pads, which are made of rubber.

[0040] Rubber pads are laid on the surfaces of the upper pressure plate 6 and the lower support plate 8 to prevent indentations and damage to the paper corner protector surface due to rigid compression, thus providing protection. At the same time, the rubber material has good friction, which can increase the adhesion with the paper corner protector surface, making it less likely for the upper pressure plate 6 to slip during the pressing process, improving the pressing stability, ensuring the accurate positioning of the paper corner protector during shaping, and improving the shaping quality.

[0041] The spacing between the two sets of vertical plates 2 of the mounting plate 5 is compatible;

[0042] Since the size of the mounting plate 5 is compatible with the spacing between the two sets of vertical plates 2, when the mounting plate 5 is lowered vertically by the electric telescopic column 4, its edge can form a precise guiding fit with the inner side of the vertical plate 2, which limits the left and right swaying and offset of the mounting plate 5 during the descent process. This allows the upper pressure plate 6 to cooperate smoothly with the lower support plate 8 to apply uniform pressure to the paper corner protector, further improving the stability and shaping accuracy of the paper corner protector during the shaping process.

[0043] Both the upper pressure plate 6 and the lower support plate 8 are made of high-strength metal.

[0044] The upper pressure plate 6 and the lower support plate 8 are made of high-strength metal. During the paper corner protector angle setting process, they can withstand the large pressure applied by the electric telescopic column 4 and the reaction force generated when the paper corner protector is pressed. This ensures that the upper pressure plate 6 can stably hold the paper corner protector, and the lower support plate 8 can reliably provide support for the paper corner protector. The two work together to maintain a stable pressure environment during the setting process, ensuring that the paper corner protector can be set at the expected angle and meet production requirements.

[0045] Working principle:

[0046] When in use, the base 1, the vertical plate 2, and the top plate 3 support the entire device;

[0047] When simultaneously shaping multiple sets of paper corner protectors, the operator places the stacked paper corner protectors on the lower support plate 8 of the horizontal plate 7. Then, the electric push rod 12 on the bottom of the horizontal plate 7 is activated. The output shaft of the electric push rod 12 pulls the connecting plate 11, causing the baffle 10 to slide on the slide rail 9. During the sliding process, the baffle 10 gradually conforms to the two sides of the stacked paper corner protectors, limiting the two sides of the stacked paper corner protectors. Next, the electric telescopic column 4 on the top plate 3 is activated. The output shaft of the electric telescopic column 4 drives the mounting plate 5 and the upper pressure plate 6 to descend vertically. Because the dimensions of the lower support plate 8 are compatible with and aligned with the dimensions of the upper pressure plate 6, the upper pressure plate... The lower plate 6, in conjunction with the lower support plate 8, lowers the paper corner protector. After the paper corner protector has been shaped, the upper pressure plate 6 is driven to move vertically upward slightly away from the paper corner protector. The electric push rod 14 on the horizontal bar 13 is activated. The output shaft of the electric push rod 14 pushes the push bar 15, which in turn pushes the stacked paper corner protectors to move horizontally on the lower support plate 8, removing the ends of the paper corner protectors from the lower support plate 8. This facilitates the paper corner protectors to be cut, sorted, and pressed for shaping. During this process, the baffles 10 on both sides effectively resist the lateral force caused by uneven pressure, ensuring that the paper corner protectors remain stable during the shaping process and preventing displacement, thereby improving the shaping effect.

[0048] in,

[0049] After the paper corner protector has been shaped, drive the upper pressure plate 6 to move vertically upward slightly away from the paper corner protector, and start the electric push rod 14 on the horizontal bar 13. The output shaft of the electric push rod 14 pushes the push bar 15, which in turn pushes the stacked paper corner protectors to move horizontally on the lower support plate 8, so as to remove the ends of the paper corner protectors from the lower support plate 8, making it easier to unload and arrange the paper corner protectors.

[0050] The push plates 16 installed at both ends of the push bar 15 are adapted to the size of the upper pressure plate 6 and the lower support plate 8 respectively. When the electric push rod 14 drives the push bar 15 to push the paper corner protector, the push plate 16 can contact the top and bottom paper corner protectors over a large area, so that the pushing force is evenly distributed on the paper corner protector, further improving the reliability of the feeding process.

[0051] Rubber pads are laid on the surfaces of the upper pressure plate 6 and the lower support plate 8 to prevent indentations and damage to the paper corner protector surface due to rigid compression, thus providing protection. At the same time, the rubber material has good friction, which can increase the adhesion to the surface of the paper corner protector, making it less likely for the upper pressure plate 6 to slip during the pressing process, improving the pressing stability, ensuring the accurate positioning of the paper corner protector during shaping, and improving the shaping quality.

[0052] Since the size of the mounting plate 5 is compatible with the spacing between the two sets of vertical plates 2, when the mounting plate 5 is lowered vertically by the electric telescopic column 4, its edge can form a precise guiding fit with the inner side of the vertical plate 2, which limits the left and right swaying and offset of the mounting plate 5 during the descent process. This allows the upper pressure plate 6 to cooperate smoothly with the lower support plate 8 to apply uniform pressure to the paper corner protector, further improving the stability and shaping accuracy of the paper corner protector during the shaping process.

[0053] The upper pressure plate 6 and the lower support plate 8 are made of high-strength metal. During the paper corner protector angle setting process, they can withstand the large pressure applied by the electric telescopic column 4 and the reaction force generated when the paper corner protector is pressed. This ensures that the upper pressure plate 6 can stably hold the paper corner protector, and the lower support plate 8 can reliably provide support for the paper corner protector. The two work together to maintain a stable pressure environment during the setting process, ensuring that the paper corner protector can be set at the expected angle and meet production requirements.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
