Description

Technical Field

[0001] The utility model relates to the field of veneer machines, in particular to a semi-automatic veneer machine with an anti-drift structure. Background Art

[0002] The veneer machine needs to apply glue to the cardboard, mainly because the coating glue has become an important part of the composite process, which directly affects the next process of the carton and the customer's online packaging. The bonding quality of the veneer is related to the physical properties of the carton, such as bonding compressive strength, flatness, burst resistance and adhesion. These indicators are crucial to the performance of the carton. Gluing can ensure that the bonding between the decorative material and the cardboard is stronger and prevent degumming during transportation or use. Therefore, gluing is a key step in the use of the veneer machine. It directly affects the quality of the cardboard and the performance of the final product. Correct operation of the veneer machine for gluing can ensure the bonding effect of the cardboard and improve the market competitiveness of the product.

[0003] After searching, Chinese patent announcement number: CN214269625U discloses a paper card conveying device for a veneer machine. The handle is turned to drive the lifting threaded rod so that the baffle drives the thin sheet to press on the upper surface of the paper card, thereby determining the gap between the baffle and the base, ensuring that the paper cards can enter the conveyor belt one by one.

[0004] In the above technical solution, a lifting threaded rod is used in conjunction with a baffle to allow the paper cards to enter the conveyor belt one by one. However, when the cardboard needs to be glued, the cardboard needs to be placed on a conveyor belt or conveyor roller for transportation. During the transportation process, it will deviate due to the effects of gravity and friction, resulting in reduced gluing effect and poor subsequent veneer effect. Therefore, a semi-automatic veneer machine with an anti-deviation structure is proposed to solve the above problem. Utility Model Content

Several groups of telescopic rods 11 and telescopic springs 12 are provided, and several groups of telescopic rods 11 and telescopic springs 12 are equidistantly distributed on the inner wall of each group of profile frames 10 and are mirror-imaged.

The bottom of the profile frame 10 is provided with an adjustment component, and the bottom of the profile frame 10 is provided with a driving component.

[0032] Reference Figure 2-Figure 4 The adjusting component includes a motor 7, the outer wall of the motor 7 is fixedly connected to the outer wall of the lifting frame 6, the output end of the motor 7 is fixedly connected to a bidirectional screw rod 8, the outer wall of the bidirectional screw rod 8 is threadedly connected to a moving seat 9, the top of the moving seat 9 is fixedly connected to the bottom of the profile frame 10, the two groups of moving seats 9 can drive the two groups of profile frames 10 to move closer or farther away from each other, so as to adjust the distance between the two groups of profile frames 10 according to the width of the cardboard, the driving component includes a fixed plate 4, the top of the fixed plate 4 is fixedly connected to the cylinder 5, the output end of the cylinder 5 is fixedly connected to the lifting frame 6, the upper surface of the lifting frame 6 is in contact with the lower surface of the moving seat 9, and the side wall of the lifting frame 6 is in contact with the outer wall of the base 1.

[0033] Reference Figure 3-Figure 4The top of the limit plate 15 is connected to the top of the limit plate 15, and the bottom end of the limit spring 18 is fixedly connected to the top of the positioning plate 17. The bottom end of the slide rod 16 is fixedly connected to the positioning plate 17. The positioning plate 17 is convenient for contacting the cardboard surface before the cardboard approaches the glue roller to provide a certain positioning function for it. The top of the limit plate 15 is rotatably connected to a screw 19. The top of the limit plate 15 is fixedly connected to the limit rod 20. The outer wall of the limit rod 20 is slidably connected to an extrusion plate 21. The lower surface of the extrusion plate 21 is fitted with the top of the slide rod 16.

[0034] Working principle: According to the width of the cardboard, the motor 7 is started to rotate the bidirectional screw 8 so that the two sets of moving seats 9 are moved closer or farther away in an arc shape, thereby adjusting the distance between the two sets of profile frames 10, and the two ends of the cardboard are inserted between the upper and lower guide rollers 14 until the front end of the cardboard contacts the surface of the conveying roller 2. The conveying roller 2 will drive the cardboard toward the gluing component 3. At the same time, due to the elastic expansion and contraction function between the telescopic rod 11 and the telescopic spring 12, the positioning function of the upper and lower sides of the cardboard will be guaranteed, thereby preventing the cardboard from offsetting during the conveying process. The rotational force of the guide roller 14 positions the cardboard while conveying it. When the cardboard gradually approaches the gluing component 3, the hydraulic cylinder drives the moving frame to descend, and the limit plate 15 will follow and descend. At this time, the positioning Plate 17 will contact the surface of the cardboard before the glue roller. Due to the elastic force of the limit spring 18, the slide bar 16 can move up and down on the surface of the limit plate 15 during the movement of the positioning plate 17, ensuring the limiting function of the positioning plate 17 while not blocking the cardboard from continuing to move closer to the glue roller. When the thickness of the cardboard is different, the forward or reverse screw 19, in conjunction with the limiting rod 20, can adjust the height of the extrusion plate 21, thereby changing the amplitude of the positioning plate 17 according to the thickness of the cardboard, avoiding the cardboard from offsetting before veneer gluing, and improving the veneer effect. Finally, the cylinder 5 can drive the lifting frame 6 to change the height position of the profile frame 10, so that the profile frame 10 is away from the top area of ​​the base 1, thereby facilitating subsequent cleaning or maintenance with the conveyor roller 2.
