Description

Technical Field

[0001] This utility model relates to a crease forming device, and more particularly to a simple crease forming device suitable for prototyping paper box blanks. Background Technology

[0002] In cardboard box design, to verify that the blank can be folded into shape as seamlessly as possible, creases often need to be pre-processed at the folding area. Currently, the conventional method is to use a ruler and a pen knife to carve these creases. Excessive force can easily cut the cardboard blank, while insufficient force results in shallow creases and poor folding performance. Alternatively, rollers are used for crease marking. Although highly precise crease marking is not required during prototyping, the straightness is poor during freehand operation, easily causing adjacent creases to be non-parallel or have excessive curvature, preventing proper folding, affecting the shape of the cardboard box after prototyping, and impacting the reference for subsequent finished product design.

[0003] Therefore, existing technologies have begun to utilize tooling equipment for crease marking. For example, prior art CN211968723U discloses a corrugated cardboard creasing device. It uses a creasing base with guide grooves and a roller assembly to mark creases. However, the depth of its guide groove is fixed, which cannot adapt to the crease depth adjustment requirements of paper blanks of different thicknesses, and it is easy to cause interference to the sides of the cardboard blank.

[0004] The prior art CN112109344A provides a packaging box creasing device and its working method. It drives the creasing head to move by a motor, but the device has a complex structure, making it difficult to flexibly adjust the force application position, and it lacks a forming groove design for creases at special angles.

[0005] In addition, existing equipment is prone to crease misalignment due to force deviation during the pressure application process, and the operating field of vision is limited, affecting the sampling efficiency.

[0006] In view of the above-mentioned shortcomings, the designer actively researched and innovated to create a simple crease forming device suitable for prototyping paper box blanks. This device can achieve non-destructive crease forming without the use of a ruler or pen knife, facilitating the rapid prototyping of paper box blanks. Utility Model Content

[0030] Detailed Implementation

[0031] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0032] like Figures 1 to 4 This invention relates to a simple crease forming device suitable for prototyping paper box blanks. It includes a support base 1, which is unique in that the support base 1 is equipped with crease grooves. These grooves work in conjunction with a subsequent force-applying rod 4 to create multiple creases and grooves on the placed paper box blank, meeting the needs for rapid prototyping and sample modeling. For user convenience, the support base 1 is equipped with displacement guide devices on one or both sides of the crease grooves. This allows for dual-sided displacement guide devices for prototyping small paper box blanks. For larger paper box blanks, a single displacement guide device is used to allow for unilateral clearance, preventing interference from the subsequently installed lifting bracket 2 and avoiding abnormal deformation. Furthermore, the lifting bracket 2 is connected to the displacement guide device, and a hanging rod 3 is mounted on the lifting bracket 2. A force-applying indentation device is movably connected to the hanging rod 3. In this way, the hanging rod 3 can provide different working force application heights, avoiding obstruction of the view caused by the force creasing device and facilitating the estimation of the crease pressing distance. During implementation, the force creasing device used includes a force application rod 4. Furthermore, in order to meet the distribution of intermittent creases and facilitate reset when not under force during use, this utility model has a reset component sleeved on the force application rod 4, and a roller 5 is movably connected to the lower end of the force application rod 4. During use, the roller 5 can press down on the cardboard blank and roll force towards the crease forming groove 9 opened on the crease groove block to form the crease required by the user. For certain special usage needs, multiple force creasing devices can be hung to achieve synchronous creasing processing.

[0033] According to a preferred embodiment of this utility model, the crease groove block includes a block body, with several connecting rods 7 extending from both ends of the block body. The connecting rods 7 are connected to the bearing base 1, and the ends of the connecting rods 7 are connected to locking nuts 8. Several crease forming grooves 9 are distributed on the upper end of the block body. This allows the crease groove block to be stably installed on the bearing base 1. Furthermore, different widths of block bodies can be selected according to actual processing needs. In addition, to form creases of different depths according to the thickness requirements of the cardboard blank, the crease forming grooves 9 are not of equal depth. Moreover, considering the user's operational convenience, to avoid pressing the wrong crease forming groove 9, the crease forming grooves 9 are not evenly spaced, making it easy for the user to identify. Considering the special characteristics of certain bending angles, the crease forming grooves 9 are not of equal width. In this way, the user can press out creases of different widths to meet different folding angles such as 45° and 70°, and to meet the sampling needs of cardboard blanks with special shapes. Still, it is also possible to provide crease forming grooves 9 with cross-sections such as U-shaped, V-shaped, and concave to meet the forming needs of different types of paper, and to form crease patterns to achieve surface crease decoration.

[0034] Furthermore, to facilitate the linear movement of the pressure-applying indentation device along the crease-forming groove 9 during user application of force, a displacement guiding device is employed. This device includes a guide rod 10 connected to the support base 1, with a slider 11 movably passing through the guide rod 10. A lifting bracket 2 is vertically mounted on the slider 11. Simultaneously, considering the possibility of multiple reciprocating pressure applications to form the crease, a guide channel is provided on the slider 11. A POM lubricating sleeve is fitted on the inner wall of the guide channel, and the guide rod 10 passes through the guide channel and contacts the POM lubricating sleeve. Thus, relying on the self-lubricating effect of POM, the slider 11 can achieve low-damping movement. Moreover, for certain special requirements, a displacement driving device can be installed on the support base 1. The driving end of the displacement driving device is connected to the slider 11; the displacement driving device can be one of an electric cylinder, a pneumatic cylinder, or a linear motor. In this way, for creases of a specific length or area distribution, the user only needs to maintain the force applied to the pressure-applying indentation device, and its linear movement is achieved by the displacement driving device, avoiding the need for the user to apply force in multiple directions such as forward and downward.

[0035] In practical application, the lifting bracket 2 of this invention includes a locking plate 12 connected to a slider screw belonging to the displacement adjustment device. A vertical support plate 13 extends upward from the locking plate 12 to achieve moderate lifting. Furthermore, several mounting holes are vertically distributed on the vertical support plate 13, and hook rods 3 are screwed into these holes. This allows for the installation of a pressure indentation device at a suitable working height. Moreover, considering the need for smooth translation and adjustment after installing the pressure indentation device, the cross-section of the hook rod 3 is circular. During use, users can install hook rods 3 of different heights and select the appropriate height for later use.

[0036] Furthermore, the reset assembly includes a sleeve 14, with a limit cap 15 installed at the upper end of the sleeve 14, preferably threaded. Both the limit cap 15 and the bottom of the sleeve 14 have concentric guide holes. During installation, the force-applying rod 4 passes through the guide hole in the sleeve 14. Simultaneously, a stop plate 16 is installed on the portion of the force-applying rod 4 located on the sleeve 14, and upper springs 17 and lower springs 18 are respectively fitted onto the upper and lower ends of the force-applying rod 4 at the stop plate 16. Thus, the user can reset the assembly after releasing the handle by the compression and rebound of the upper springs 17 and lower springs 18. Additionally, connecting hooks 19 are distributed on the outer side of the sleeve 14, and the connecting hooks 19 are movably connected to the hook rod 3. This allows for convenient and stable connection, and quick removal when replacement is needed. Considering that the connecting hook 19 will be subjected to downward pressure from the user during use, in order to improve its service life, reinforcing ribs 20 can be distributed at the joint between the sleeve 14 and the connecting hook 19. These ribs can also be made of lightweight but relatively hard materials such as titanium alloy. Furthermore, considering the user's grip comfort and to prevent easy slippage during use, a handle 21 is installed at the upper end of the force-applying rod 4.

[0037] The working principle of this utility model is as follows:

[0038] Taking the prototyping of a small cardboard box blank as an example, the user selects a roller 5 of appropriate width according to needs and installs it into the pressure-applying creasing device. Then, the cardboard box blank is placed on the crease groove block. Using a pre-drawn reference line on the cardboard box blank as a template, the user moves the reference line to the position overlapping with the corresponding crease forming groove 9, based on the actual required crease type. Next, the user holds the pressure-applying creasing device and uses the lifting bracket 2 to drive the displacement guide device, positioning the roller 5 at the end of the reference line. At this time, no downward force is applied to the pressure-applying creasing device, and the roller 5 does not contact the cardboard box blank, preparing for line drawing. The cardboard box blank can be clamped and positioned to the supporting base 1 using clips or supported by hand to prevent improper displacement of the cardboard box blank during subsequent use.

[0039] The user then holds the force-applying lever 4 and applies downward force, causing the roller 5 to press against the cardboard box blank. Afterward, the downward force is maintained while pushing forward. Guided by the displacement guide device, a complete crease line is drawn. During this process, the user stops applying force when the roller 5 reaches the end of the reference line. For some dotted or discontinuous creases, effective force control allows for control of the roller 5's contact and lifting.

[0040] For quick prototyping without reference lines, users can directly use the crease groove block and roller 5 to draw creases without a template according to their own needs, which facilitates the final forming of various non-standard shaped cardboard boxes, completes pre-prototyping, and provides design ideas.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
