Description

Technical Field

[0001] The utility model relates to the technical field related to paper box forming equipment, in particular to a cardboard top and bottom cover glue spraying box folding machine. Background Art

[0002] A top-bottom box generally refers to two paper boxes, one large and one small, that are placed together. They are formed by folding and gluing cardboard. Generally, formed sheet metal and stamping plates are used to form the box. As the cardboard is pushed down, it gradually folds into shape. However, some cardboards are very thin, that is, paper sheets. Therefore, the distance between the stamping plate and the sheet metal needs to be considered during stamping. If the distance is too wide and the paper is too thin, it will not be able to fold and bond completely. After being pushed down, the box will easily fall apart and turn into cardboard again. If the distance is too narrow, there is no gap left to cushion the deformation and folding of the cardboard, and the cardboard will easily tear, and even wear and tear of the stamping plate and the formed sheet metal.

When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may also be an element centered thereon. When the number of an element is referred to as having "plurality", it may be any number of two or more. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings:

[0022] like Figure 1-2 As shown, in this embodiment, a cardboard top and bottom cover glue folding machine is provided, including a forming mechanism 3 and a frame. The forming mechanism 3 includes a pair of adjustment platforms 9 slidably mounted on the frame. The pair of adjustment platforms 9 are symmetrically arranged on the frame. The adjustment platforms 9 are provided with a forming sheet metal 6. The forming sheet metal 6 is fixedly arranged on one side of the adjustment platform 9. As mentioned above, the spacing between the pair of adjustment platforms 9, that is, the position on the frame is adjustable, and the forming sheet metal 6 is arranged on the adjustment platform 9, so the distance between the pair of forming sheet metals 6 can be adjusted to adapt to more cardboards of different sizes to be formed into paper boxes. The forming sheet metals 6 provided on each of the pair of adjustment platforms 9 are symmetrically arranged on the frame, so the pair of forming sheet metals 6 are surrounded to form a forming frame, and the width of the forming frame can be adjusted in size according to the cardboard to be formed and punched.

[0023] A through slot 7 is provided in the middle of the formed sheet metal 6, and a counter-pressure cylinder 4 is installed on the adjusting platform 9. A folding sheet metal 5 is fixed to the end of the piston rod of the counter-pressure cylinder 4. The folding sheet metal 5 and the formed sheet metal 6 are coplanar or non-coplanar. When cardboard of normal thickness needs to be stamped and formed, the folding sheet metal 5 and the formed sheet metal 6 are coplanar, and the cardboard moves directly downward to form. When processing thinner cardboard, the folding sheet metal 5 needs to be moved inward to press and bond the hinges.

[0024] The area of ​​the through slot 7 is larger than that of the folding sheet metal 5. The counter-pressure cylinder 4 controls the folding sheet metal 5 to pass through the through slot 7 and through the forming sheet metal 6. The forming mechanism 3 includes a stamping plate 8 connected to the frame in a lifting manner. Specifically, in this embodiment, a motor and a rack are provided on the frame. The stamping plate 8 is fixedly arranged at the bottom of the rack. The motor and the rack are connected in a transmission manner to control the lifting of the stamping plate 8 relative to the frame. The punching plate 8 is positioned between a pair of adjustment platforms 9, mounted above them. The top of the punching plate 8 is integrally formed with side panels 10 extending upward. When processing thinner cardboard, the side panels 10 cooperate with the folding sheet metal 5 to fold and press the cardboard. When the punching plate 8 punches the cardboard into the middle of the forming sheet metal 6, it briefly pauses. During the forming process, the cardboard rubs against the forming sheet metal 6 and the side panels 10 of the punching plate 8, causing friction to stick in the middle. Since the cardboard itself is light, it can remain suspended in the middle of the forming sheet metal without external force. Specifically, a pair of counter-pressure cylinders 4 are symmetrically arranged on the frame, with their piston rods facing each other. At this point, the counter-pressure cylinders 4 control the folding sheet metal 5 to move simultaneously toward the center, folding and gluing the carton securely. This is because the cardboard is glued before forming.

[0025] In this embodiment, it also includes a hopper mechanism 1 and a feeding mechanism 2. Both the hopper mechanism 1 and the feeding mechanism 2 are installed on the frame, and the feeding mechanism 2 is mounted above the hopper mechanism 1; the hopper mechanism 1 is used to store unformed cardboard, and the feeding mechanism 2 can absorb and transport the cardboard to the forming mechanism 3.

[0026] Specifically, a linear guide is provided at the bottom of the adjustment platform 9, and the adjustment platform 9 is slidably mounted on the frame via the linear guide, and the adjustment platform 9 can slide freely on the frame via the linear guide. The adjustment platform 9 is also fixedly provided with a shaft sleeve 11, and the frame is fixedly provided with a guide rod 12. The shaft sleeve 11 is sleeved on the guide rod 12 and is slidably connected to the guide rod 12. Specifically, a positioning bolt is threadedly connected to the adjustment platform 9. The positioning bolt can be rotated to penetrate the adjustment platform 9 and abut against the linear guide, thereby locking the position of the adjustment platform 9 on the frame.

[0027] In this embodiment, the adjustment platform 9 is provided with a fine-tuning component, and a pair of support columns 13 are slidably provided on the adjustment platform 9. A storage rod 14 is fixedly provided on the top of the support column 13. The storage rod 14 is used to temporarily place the cardboard waiting to be stamped and formed. The support column 13 is movably connected to the adjustment platform 9 through the fine-tuning component.

[0028] Specifically, the fine-tuning component includes a synchronous mounting plate 15 and a distance controller. The bottom of a pair of support columns 13 is fixedly connected to the synchronous mounting plate 15. A linear guide rail is installed at the bottom of the synchronous mounting plate 15. The synchronous mounting plate 15 is slidingly connected to the adjustment platform 9 through the linear guide rail. The distance controller is used to adjust the position of the synchronous mounting plate 15 on the adjustment platform 9.

[0029] The distance controller includes a pair of locating bearings 16 fixedly mounted on the adjustment platform 9. Both ends of a screw 18 are rotatably connected to the locating bearings 16. A screw sleeve 17 is fixedly mounted on one end of the synchronous mounting plate 15. The screw sleeve 17 is sleeved on the screw 18 and threadedly connected to the screw 18. The screw 18 is rotatably connected to the adjustment platform 9 via a bearing seat. The movement of the screw sleeve 17 can be controlled by rotating the screw 18. Preferably, one of the bearing seats is provided with a positioning bolt that passes through the bearing seat and is threadedly connected thereto. Rotating this positioning bolt can lock the screw 18, thereby preventing the screw 18 from rotating, thereby locking the position of the synchronous mounting plate 15 relative to the frame.

[0030] The technical features of the above-described embodiments can be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there are no contradictions in the combination of these technical features, they should be considered to be within the scope of this specification. For those skilled in the art, without departing from the concept of the utility model, they can also make several variations and improvements, which fall within the scope of protection of the utility model. Therefore, the scope of protection of this utility model patent shall be based on the appended claims.
