Technical Field

[0001] This utility model relates to the field of paper straw production technology, and in particular to a paper straw embossing and forming device. Background Technology

[0002] Paper straws are an environmentally friendly beverage tool that uses paper as its core material to replace plastic straws. They are mainly used for drinking various hot and cold beverages. Due to their biodegradable properties, they have become a common choice for reducing plastic and protecting the environment. Paper straws usually require indentation during the production process, which is one of the key process steps to ensure their molding stability, structural strength and user experience.

[0003] A search revealed that the utility model patent with authorization announcement number CN222610619U discloses a paper straw creasing and forming device. Although the device can complete the creasing and forming operation of paper straws of different specifications, after completing a single creasing operation, the creasing paper straw needs to be removed before the next paper straw can be placed. The interval between two adjacent creasing operations is relatively long, and the processing efficiency needs to be improved.

[0004] Therefore, it is necessary to invent a paper straw embossing device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a paper straw creasing and forming device that can simultaneously feed the previous paper straw and load the next paper straw during the current paper straw creasing process, effectively shortening the interval between two adjacent creasing operations and thus improving the paper straw creasing efficiency. This solves the problem in the background art where the next paper straw can only be placed after the creasing is removed, resulting in a long interval between two adjacent creasing operations and reduced processing efficiency.

[0006] According to one aspect of this disclosure, the following technical solution is provided: a paper straw embossing device, comprising:

[0007] The mounting mechanism is used to provide a mounting base for the locking indentation mechanism and the paper straw support and displacement mechanism;

[0008] A locking indentation mechanism, used for indenting the paper straw and locking the paper straw support and repositioning mechanism; and

[0009] The paper straw support and shifting mechanism includes a servo motor fixedly installed at the bottom of the back panel. The output shaft of the servo motor extends to the front of the back panel and is fixedly connected to a shifting disk. Support rods are fixedly installed at the top and bottom of the front of the shifting disk. Locking grooves are provided at the top and bottom of the shifting disk. A reinforcing ring fixedly installed at the bottom of the front of the back panel is rotatably sleeved on the outside of the shifting disk through a bearing. A clearance channel that is collinear with the adjacent locking groove in the vertical direction is provided at the top of the reinforcing ring.

[0010] According to at least one embodiment of the paper straw creasing forming apparatus of the present disclosure, the mounting mechanism includes a base, and a back plate is fixedly disposed on the rear side of the top of the base.

Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0026] Figure 1 This is a schematic diagram of the overall structure of a paper straw creasing and forming apparatus according to one embodiment of the present disclosure.

[0027] Figure 2 This is a schematic diagram of the mounting mechanism 1 and the locking indentation mechanism 2 of a paper straw indentation forming apparatus according to one embodiment of the present disclosure.

[0028] Figure 3 This is a schematic diagram of the paper straw support and displacement mechanism 3 of a paper straw embossing and forming apparatus according to one embodiment of the present disclosure.

[0029] like Figures 1-3 As shown, the paper straw creasing and forming device disclosed herein may include components such as: mounting mechanism 1, locking creasing mechanism 2, and paper straw support and repositioning mechanism 3.

[0030] like Figure 2 As shown in this disclosure, the installation mechanism 1 includes a base 11, which is integrally cast from HT300 gray cast iron. The cast iron material has high rigidity and low deformation characteristics, which can effectively absorb the impact force during the indentation process. The bottom edge of the base 11 is provided with 4 sets of detachable rubber anti-slip pads, which not only prevents the device from sliding during operation, but also reduces the transmission of vibration to the ground. The flatness error of the top surface of the base is controlled within 0.1mm / m, providing a precise benchmark for the installation of subsequent components. A back plate 12 is fixedly installed on the rear side of the top of the base 11. It is made of food-grade 304 stainless steel plate. Stainless steel material has both rust resistance and deformation resistance, and meets the hygiene requirements of paper straw production, that is, it avoids metal corrosion and contamination of raw materials. A top plate 13 is fixedly installed on the top of the back plate 12. It is made of the same material as the back plate 12. The bottom front sides of the top plate 13 are fixedly connected to columns 14 fixedly installed on the top of the base 11.

[0031] This allows for the installation and fixation of the servo motor 31 using the back plate 12, and the installation and fixation of the electric push rod 21 using the top plate 13.

[0032] like Figure 2 As shown, in a preferred embodiment, the locking indentation mechanism 2 includes an electric push rod 21 fixedly mounted on the top of the top plate 13. A servo electric push rod of model DTZ300 is selected. The output shaft of the electric push rod 21 extends to the bottom of the top plate 13 and is fixedly connected to a lifting plate 22, which is made of 6061 aluminum alloy. Two sets of guide rods are symmetrically arranged on both sides of the top of the lifting plate 22. The guide rods pass through pre-set copper sleeve guide holes in the top plate 13 to ensure that the lifting plate moves only in the vertical direction and prevents lateral deviation. A vertical plate 23, made of 304 stainless steel, is fixedly mounted on the bottom of the lifting plate 22. An indentation strip 24, made of hard alloy, is fixedly mounted on the bottom of the vertical plate 23. A locking pin 25 is slidably mounted through the top rear side of the lifting plate 22 in the vertical direction. The bottom end of the locking pin 25 is located inside the clearance channel 36. A return spring 26, fixedly connected between the lifting plate 22 and the locking pin 25, is sleeved on the outside of the locking pin 25. A cylindrical helical spring (material 65Mn, elastic coefficient 8N / mm) of Φ2mm×15mm is selected.

[0033] Therefore, the electric push rod 21 drives the lifting plate 22, which is guided by the guide rod, to move continuously downward. When the lifting plate 22 moves downward, it drives the locking pin 25 located inside the avoidance channel 36 to insert into the inner side of the adjacent locking groove 34, thereby locking and reinforcing the shift plate 32. Then the lifting plate 22 continues to move downward. At this time, the return spring 26 is stretched. At the same time, the lifting plate 22 drives the embossing strip 24 through the vertical plate 23 to move continuously closer to the paper suction tube located at the embossing station until the embossing of the paper suction tube is completed. Then, the electric push rod 21 drives the lifting plate 22, which is guided by the guide rod, to move upward and reset.

[0034] like Figure 3 As shown in this disclosure, the paper straw support and shifting mechanism 3 includes a servo motor 31 fixedly installed at the bottom of the back of the back plate 12. A high-precision servo motor of model 130STM-04030 is selected. The output shaft of the servo motor 31 extends to the front of the back plate 12 and is fixedly connected to a shifting disk 32, which is a 6061 aluminum alloy forging. Support rods 33 are fixedly installed at the top and bottom of the front of the shifting disk 32. They are 304 stainless steel round rods with polished surfaces to avoid scratching the inner wall of the paper straw. Locking grooves 34 are provided at the top and bottom of the shifting disk 32. A reinforcing ring 35 is fixedly installed at the bottom of the front of the back plate 12 through a bearing rotation sleeve on the outside of the shifting disk 32. A clearance channel 36 is provided at the top of the reinforcing ring 35, which is collinear with the adjacent locking groove 34 in the vertical direction.

[0035] Therefore, during the creasing process of the paper straw on the outer side of the upper support rod 33, the creasing paper straw on the outer side of the lower support rod 33 can be removed, and then the paper straw to be creasing can be taken and placed on the outer side of the support rod 33. After the subsequent creasing of the paper straw on the outer side of the upper support rod 33 is completed, and the creasing mechanism 2 is locked and reset, the servo motor 31 drives the two support rods 33 to rotate and change positions through the shifting plate 32. Compared with the prior art, the feeding of the previous paper straw and the feeding of the next paper straw can be carried out during the current paper straw creasing process, which effectively shortens the interval time between two adjacent creasing operations and thus improves the paper straw creasing efficiency.

[0036] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0037] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
