Description

Technical Field

[0001] The utility model relates to the field of carton production equipment, in particular to a knife die structure for carton production. Background Art

[0002] In modern society, with the booming development of e-commerce and the rapid expansion of the logistics industry, cartons of various sizes and shapes have become a core demand in the packaging industry. During the carton production process, they need to be die-cut to form the corresponding size and shape. Die-cutting is usually achieved by a die-cutter driving a die to press down and cut the cardboard.

[0003] Existing cutting dies usually consist of a mounting plate, a long blade and multiple sponge pads. The blade back is embedded in the mounting plate, the blade corresponds to the position of the cardboard to be cut, and the sponge pads are glued to the mounting plate and located on both sides of the blade. Their main function is to prevent the cardboard from being damaged or deformed during the cutting process.

[0004] Since the blade and sponge pad are usually fixed to the mounting plate by welding, riveting or gluing, when the blade or sponge pad is damaged, it cannot be removed and replaced separately, and the entire cutting die can only be replaced, which not only increases production costs but also causes a huge waste of resources.

[0005] To address these issues and improve the flexibility and resource utilization efficiency of the die cutter structure during carton production, it is necessary to improve and innovate the existing die cutter structure. By designing a detachable die cutter structure, the blade and sponge pad can be replaced and reused separately, thereby reducing production costs.

[0006] To sum up, this patent aims to provide a detachable knife die structure, which optimizes the installation method of the blade and sponge pad to achieve their independent replacement and reuse, so as to overcome the shortcomings of the existing technology and promote the further development and application of carton production technology.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] The utility model provides a knife die structure for carton production, which is used to solve the problem of how to separately disassemble and replace a knife blade 1 and a sponge pad 2.

[0037] See Figure 1-Figure 3 As shown, Figure 1 This is a three-dimensional diagram of the knife die structure used for carton production in the embodiment. Figure 2-3 It is a partial cross-sectional view of the folding and forming of the cutting die structure for carton production in the embodiment. The cutting die structure for carton production includes a blade 1, a sponge pad 2, a mounting plate 3, a knife seat 4 and a connecting piece 6.

[0038] The blade 1 is in the shape of an elongated strip and comprises a cutting edge 11 and a blade back 12. The blade back 12 is provided with a sliding channel 13, which extends along the length direction of the blade 1.

[0039] The mounting plate 3 is used to connect to the die-cutting machine, and has a mounting groove 31 corresponding to the position of the cardboard to be cut.

[0040] There are multiple sponge pads 2 and multiple blade holders 4. The blade holders 4 are removably mounted within the mounting slot 31 via screwing or snapping, with the blade holders 4 spaced apart along the length of the mounting slot 31. One end of the blade holder 4 has a slot 41 for inserting the blade back 12. This end of the blade holder 4 is connected to two sponge pads 2 via adhesive, snapping, or screwing, with the two sponge pads 2 positioned on either side of the slot 41. The blade holder 4 also has a connection hole 42 that communicates with the slot 41.

[0041] The connecting member 6 is detachably disposed in the connecting hole 42 and the sliding channel 13 , and fixes the blade 1 and the blade holder 4 .

[0042] When installing the knife die structure for carton production according to the above technical solution, first, multiple sponge pads 2 are connected in pairs to one end of each knife holder 4 having a slot 41, and then, the knife back 12 is inserted into the slot 41 of each knife holder 4. At this time, the connection hole 42 and the sliding channel 13 are relative and connected, and then the connecting member 6 is detachably arranged in the connection hole 42 and the sliding channel 13, and the blade 1 and the knife holder 4 are fixed. Finally, the knife holder 4 is detachably installed in the mounting groove 31 of the mounting plate 3. It can be seen that the blade 1 and the knife holder 4 of the knife die structure are detachably connected through the connecting member 6, the sponge pad 2 is connected to the knife holder 4, and the knife holder 4 is detachably connected to the mounting plate 3. In this way, the blade 1 and the sponge pad 2 of the knife die structure can be removed and replaced separately from the mounting plate 3, thereby realizing reuse and greatly reducing production costs.

[0043] The above-mentioned connecting member 6 can use existing threaded parts such as bolts, and be threadedly connected to the blade 1 and the blade holder 4 at the same time, so that the blade 1 and the blade holder 4 can be detachably fixed. The connecting member 6 can also use the existing bolt and nut structure to tightly connect the blade 1 and the blade holder 4, or a clamping structure to fix the blade 1 and the blade holder 4, etc., as long as the connecting member 6 can achieve detachable connection between the blade 1 and the blade holder 4.

[0044] See Figure 1 and Figure 2As shown, Figure 2 This is a cross-sectional view of a first connection structure between the tool holder and the mounting plate. In one embodiment of the mounting groove 31, the mounting groove 31 is a stepped groove. The cross-sectional shape of the tool holder 4 matches the cross-sectional shape of the mounting groove 31. The mounting plate 3 includes a facing working surface 32 and a back surface 33. The end surface of the tool holder 4 having the slot 41 is flush with the working surface 32. This effectively ensures that the tool holder 4 is securely mounted within the mounting groove 31, thereby improving the cutting effect of the die structure. The end surface of the tool holder 4 having the slot 41 is flush with the working surface 32, which can avoid affecting cutting.

[0045] See Figure 1 and Figure 2 As shown, in the first embodiment in which the tool holder 4 is detachably mounted in the mounting groove 31, a stepped surface 34 is provided in the mounting groove 31. The tool holder 4 and the mounting plate 3 are connected by a detachable structure 5, which includes a pressing plate 51 and at least two screw members 52. The pressing plate 51 is connected to each tool holder 4 by abutting or integral connection. When the tool holder 4 is inserted into the mounting groove 31 from the back side 33, the screw member 52 passes through the pressing plate 51 and is screwed onto the mounting plate 3, and is used to drive the pressing plate 51 to move from the back side 33 toward the working surface 32, so that the tool holder 4 is tightly abutted against the stepped surface 34, thereby tightly connecting the tool holder 4 and the mounting plate 3. In this embodiment, there can be only one or more pressing plates 51, and the number of screw members 52 is much less than the number of tool holders 4. It can be seen that the mounting plate 3 and multiple tool holders 4 can be connected at one time through the detachable structure 5, which greatly improves the efficiency of disassembly and assembly.

[0046] See Figure 3 As shown, Figure 3 This is a cross-sectional view of the second connection structure between the tool holder and the mounting plate. In the second embodiment in which the tool holder 4 is detachably mounted in the mounting groove 31, a stepped surface 34 is provided in the mounting groove 31. The tool holder 4 and the mounting plate 3 are connected by a detachable structure 5, which includes a pressure plate 51 and a screw member 52. When the tool holder 4 is inserted into the mounting groove 31 from the working surface 32, one end of the screw member 52 is connected to the pressure plate 51 by abutment or rotational connection, and the other end is screwed to the tool holder 4. The screw member 52 is used to drive the pressure plate 51 to move from the back surface 33 toward the working surface 32, so that the pressure plate 51 is tightly abutted against the mounting plate 3, and drives the tool holder 4 to tightly abut against the stepped surface 34, so as to tightly connect the tool holder 4 and the mounting plate 3. In this embodiment, the number of pressure plates 51 and screw members 52 is the same as the number of tool holders 4, and corresponds one to one. It can be seen that the detachable structure 5 can separately and tightly connect the mounting plate 3 and each knife seat 4, greatly improving the connection strength between the mounting plate 3 and the knife seat 4, thereby further improving the cutting effect of the knife die structure.

[0047] See Figure 2 and Figure 3As shown, based on either of the above two embodiments, a clearance groove 35 is formed on the back surface 33 of the mounting plate 3, which is connected to the mounting groove 31. The clearance groove 35 is used to accommodate the pressing plate 51. This effectively prevents the detachable structure 5 from exposing the back surface 33 of the mounting plate 3 and interfering with the connection between the mounting plate 3 and the die-cutting machine.

[0048] See Figure 2 As shown, in one embodiment of the sponge pad 2, the sponge pad 2 includes an elastic body 21 and a connecting portion 22 that are connected as one body. The elastic body 21 abuts against the knife seat 4 and is located on the outside of the mounting plate 3. The connecting portion 22 is located between the blade 1 and the groove wall of the slot 41, and the connecting portion 22 has a clearance hole 23 for communicating with the connecting hole 42. The connecting member 6 is detachably arranged in the connecting hole 42, the clearance hole 23 and the sliding channel 13, and fixes the blade 1, the sponge pad 2 and the knife seat 4. It can be seen that the knife die structure can not only detachably connect the blade 1 and the knife seat 4 through the connecting member 6, but also detachably connect the sponge pad 2 and the knife seat 4. In this way, the sponge pad 2 can be easily disassembled and replaced separately.

[0049] See Figure 3 As shown, the sponge pad 2 can also be directly bonded to the knife seat 4, but in this case the sponge pad 2 needs to be replaced together with the knife seat 4. Although it is also possible to remove and replace the sponge pad 2 from the mounting plate 3 alone, the effect of reducing production costs is not as good as the previous embodiment.

[0050] Based on the above embodiment, the connecting portion 22 is elastic and is used to eliminate the gap between the blade 1 and the slot wall of the slot 41. In this way, the connecting portion 22 not only facilitates the detachable connection between the connecting member 6 and the sponge pad 2 and the knife holder 4, but also makes the connection structure between the blade 1 and the knife holder 4 more stable and acts as a shock absorber for the cutting action of the blade 1, thereby improving the die-cutting quality of the die-cutting structure.

[0051] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
