Description

Technical Field

[0001] This utility model relates to the technical field of hot-cutting equipment for tissue packaging, and more specifically, to a tissue hot-cutting die that facilitates changing the tear shape. Background Technology

[0002] In the production of facial tissues, a hot-cutting die is used to cut a specific tear shape on the tissue packaging so that users can easily tear open the packaging and remove the tissues. However, existing hot-cutting dies are usually fixed to a specific tear shape. When the tear shape needs to be changed, the entire hot-cutting device must be replaced, which not only increases costs but also consumes time. Therefore, it is necessary to design a hot-cutting die that allows for easy replacement of the tear shape. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and to provide a paper towel hot-cutting die that is easy to change the tear shape, so as to solve the above-mentioned shortcomings.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] This utility model discloses a tissue paper hot-cutting die that facilitates the replacement of tear-out shapes. It includes a base, the upper surface of which is provided with mounting holes of a size that matches the installation structure of the hot-cutting machine, and the lower surface of the base is symmetrically provided with positioning posts. A die template is installed on the positioning posts, and the two ends of the base are provided with locking structures to fix the base and the die template in place.

[0006] Preferably, the cutting template is provided with positioning holes that match the positioning posts, and the positioning holes are sleeved with the positioning posts to position the base and the cutting template.

[0007] Preferably, the locking structure includes through holes at both ends of the base, a sliding groove communicating with the through holes, a locking member disposed in the through holes and the sliding groove, and a guide rod and a spring disposed in the through holes. The guide rod is horizontally disposed in the through holes, and the guide rod is sleeved with the spring. One end of the spring abuts against the locking member.

[0008] Preferably, the locking component includes a horizontal plate, a vertical plate, and a wedge block connected in sequence. The horizontal plate is movably connected to a slide groove, and the horizontal plate moves horizontally within the slide groove. The horizontal plate and the vertical plate are vertically connected, and the vertical plate passes through a through hole. One side of the lower end of the vertical plate is fixedly connected to the wedge block. The horizontal plate pulls the vertical plate to move horizontally within the through hole, and simultaneously drives the wedge block to move. A guide rod passes through the vertical plate, and the vertical plate has a movable hole that matches the guide rod. The guide rod guides the horizontal movement of the vertical plate. The upper surface of one end of the horizontal plate has anti-slip textures. By pulling the end of the horizontal plate with anti-slip textures, the horizontal movement of the horizontal plate is controlled, and the vertical plate compresses the spring to store force.

[0009] Preferably, the die template has a slot, and one side of the slot has an inclined face. The inclined wedge is inserted from the top of the slot. After the horizontal plate is released, the spring returns to its original position, causing the inclined wedge to abut against the inclined face.

[0010] Preferably, a hot cutting blade is provided on the working surface of the blade template. The hot cutting blade is long and has a break. The break does not generate cutting force when processing the tissue box, so that the shape of the long strip of tissue box tear is retained on the tissue box after hot cutting, thus protecting the tissue box before the tissue box is opened.

[0011] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0012] This utility model provides a tissue paper hot-cutting die with easily interchangeable tear-off shapes, allowing users to quickly change die templates with different tear-off shapes without tools. This greatly improves production efficiency, especially when frequent changes in product specifications or small-batch customized production are required. Because the die template can be quickly changed, manufacturers can flexibly adjust production plans according to market demand, supporting product lines with multiple tear-off shapes without needing to prepare separate hot-cutting equipment for each shape, thus reducing equipment investment costs. The design of the positioning pins and positioning holes between the base and the die template ensures precise alignment during each installation, avoiding cutting errors caused by positional deviations. The tight fit between the wedge block and the inclined card surface in the locking structure ensures the stability of the die template during operation, thereby maintaining the consistency and reliability of processing quality. The locking structure adopts a spring reset mechanism, which is simple and intuitive to operate. Simply pulling the horizontal plate is enough to install and remove the die template. This design not only simplifies the operation process but also reduces maintenance time and labor costs. Attached Figure Description

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0024] Combination Figures 1-4 This utility model discloses a tissue paper hot-cutting die that facilitates the replacement of tear-off shapes. It includes a base 1, which is connected to a hot-cutting machine and rises and falls under the control of the hot-cutting machine to process tissue paper packaging. The upper surface of the base 1 is provided with mounting holes 11, the size of which matches the mounting structure of the hot-cutting machine, making it suitable for various models of hot-cutting machines commonly found on the market. The lower surface of the base 1 is symmetrically provided with positioning posts 12, on which a die template 2 is installed. The die template 2 is provided with positioning holes 21 that match the positioning posts 12. The positioning holes 21 are sleeved with the positioning posts 12 to position the base 1 and the die template 2. The two ends of the base 1 are provided with locking structures to fix the base 1 and the die template 2.

[0025] The locking structure includes through holes 13 at both ends of the base 1, a slide groove 14 communicating with the through holes 13, a locking member 15 disposed in the through holes 13 and the slide groove 14, and a guide rod 16 and a spring 17 disposed in the through holes 13. Specifically, the locking member 15 includes a horizontal plate 151, a vertical plate 152 and a wedge block 153 connected in sequence. The horizontal plate 151 is movably connected to the slide groove 14 and moves horizontally within the slide groove 14. The horizontal plate 151 and the vertical plate 152 are vertically connected. The vertical plate 152 passes through the through hole 13, and one side of the lower end of the vertical plate 152 is fixedly connected to the wedge block 153. The horizontal plate 151 pulls the vertical plate 152 in the through hole 13. The vertical plate 152 moves horizontally and simultaneously drives the wedge block 153 to move. A guide rod 16 is horizontally installed in the through hole 13. The guide rod 16 passes through the vertical plate 152. The vertical plate 152 has a movable hole that matches the guide rod 16. The guide rod 16 guides the horizontal movement of the vertical plate 152. At the same time, a spring 17 is sleeved on one end of the guide rod 16. Under the action of the spring 17, the wedge blocks 153 at both ends of the base 1 move closer to each other to fix the blade template 2. The upper surface of one end of the horizontal plate 151 has anti-slip texture. By pulling the end of the horizontal plate 151 with anti-slip texture, the horizontal plate 151 is controlled to move horizontally. The vertical plate 152 compresses the spring 17 to store force.

[0026] The die template 2 has a slot 22, and a beveled face 221 is provided on one side of the slot 22. The beveled wedge 153 is inserted from the upper end of the slot 22. After the horizontal plate 151 is released, the spring 17 returns to its original position, causing the beveled wedge 153 to abut against the beveled face 221. The beveled wedge 153 and the beveled face 221 make contact through the bevel. The horizontally moving beveled wedge 153, guided by the positioning post 12 and the positioning hole 21, will apply a vertical force to the die template 2, so that the base 1 and the die template 2 are installed tightly. When it is necessary to disassemble the die template 2, simply pull the horizontal plate 151 out of the slide groove 14 to control the beveled wedge 153 to separate from the beveled face 221, and then separate the base 1 and the die template 2.

[0027] A hot cutting blade 23 is provided on the working surface of the blade template 2. The hot cutting blade 23 is long and narrow. In this embodiment, a lip-shaped structure is provided in the middle of the long strip of the hot cutting blade 23. The processed tissue paper tear is lip-shaped. A break 231 is provided on the hot cutting blade 23. The break 231 does not generate cutting force when processing the tissue paper packaging, so that the shape of the long strip of tissue paper tear is retained on the tissue paper packaging, thus protecting the tissue paper before the tissue paper packaging is opened.

[0028] Working process: When installing a knife template 2 with a specific tear-out shape, first align the positioning hole 21 on the knife template 2 with the positioning post 12 on the lower surface of the base 1, and fit it onto the positioning post 12, ensuring that the two are correctly aligned. Manually pull the horizontal plate 151, and the vertical plate 152 compresses the spring 17 to store force, aligning the slot 22 on the knife template 2 with the wedge blocks 153 at both ends of the base 1. At this time, release the horizontal plate 151. Due to the action of the spring 17, the wedge block 153 is pushed to abut against the inclined face 221, gently pressing down the knife template 2, causing the wedge block 153 to slide along the inclined face 221 on one side of the slot 22. As the wedge block 153 enters, once the wedge block 153 is fully inserted into the slot 22 and the inclined surface of the wedge block 153 contacts the inclined face 221, the spring 17 releases its stored force, pushing the wedge block 153 to fit tightly against the inclined face 221. After installation, Under the control of the hot cutting machine, the base 1 moves up and down, driving the hot cutting blade 23 on the blade template 2 to cut the tissue box. The lip-shaped structure on the hot cutting blade 23 will cut a corresponding lip-shaped tear on the tissue box, while the break 231 set on the hot cutting blade 23 will not generate cutting force, ensuring that the tear shape is completely preserved on the tissue box, while providing a good opening experience. To replace the blade template 2, simply grasp the anti-slip texture at one end of the horizontal plate 151 with your fingers and pull it outward, so that the horizontal plate 151 moves horizontally in the slide groove 14. The movement of the horizontal plate 151 will drive the vertical plate 152 and the inclined wedge block 153 to move outward synchronously, overcoming the resistance of the spring 17, until the inclined wedge block 153 separates from the inclined card surface 221. At this time, the blade template 2 can be easily removed from the base 1 for replacement with other blade templates 2 with different tear shapes.

[0029] Example 2:

[0030] Combination Figures 1-3 and Figure 5 In this embodiment, a Chinese knot-shaped structure is provided in the middle of the long strip of the hot cutting blade 23, and the tear edge of the processed tissue paper is in the shape of a Chinese knot. Other structures are the same as in Embodiment 1.

[0031] Example 3:

[0032] Combination Figures 1-3 and Figure 6 In this embodiment, a heart-shaped structure is provided in the middle of the long strip of the hot cutting blade 23, and the tear of the processed tissue is heart-shaped. Other structures are the same as in Embodiment 1.

[0033] Example 4:

[0034] Combination Figures 1-3 and Figure 7 In this embodiment, the hot-cutting blade 23 has a double heart-shaped structure in the middle of its long strip, resulting in a double heart-shaped tear in the tissue box after processing. Other structures are the same as in Embodiment 1.
