Description

Technical Field

[0001] The present application relates to the technical field of cutting tools for bag throwing machines, and particularly relates to a cutting knife and a bag throwing machine. Background Art

[0002] As an automated processing equipment widely used in the food, pharmaceutical and daily necessities industries, the main function of a bag throwing machine is to accurately cut the strip-connected packaging bags and accurately place the cut single-bag material packages into the target object (or on the target object). For example, the material packages in instant noodles, or the drying or anti-corrosion packages in medicine and food bags. In the whole processing process of the bag throwing machine, how to efficiently and accurately cut the strip-shaped packaging bags becomes the most crucial process.

[0003] In the existing bag throwing machine technology, taking the Chinese patent document with the publication number CN109733697A (a high-speed bag throwing machine) as an example, it uses two mutually meshing cutting knives to achieve the cutting operation of strip-shaped packaging bags. However, this cutting knife design has certain technical problems: the matching accuracy between the two cutting knives needs to reach an extremely high standard, and there are also certain processing errors in the cutting knives themselves. It is very difficult to adjust the matching gap between the two cutting knives. If the matching gap is too large, it will cause the strip-shaped packaging bags to not be effectively cut, affecting the production efficiency; if the matching gap is too small, it will generate a large cutting noise and increase equipment wear. This brings great challenges to the installation and debugging work of the cutting knives. Summary of the Utility Model

[0004] In order to solve the technical problems in the related art, the present application provides a cutting knife and a bag throwing machine.

[0043] The following describes the technical solutions of the present application in detail with reference to the accompanying drawings.

[0044] Embodiment 1

[0045] As Figures 1 to 8 shown, according to the first aspect of the present application, this embodiment provides a cutter 101 for cutting materials of a bagging machine 100, including a first slicing assembly 1 and a second slicing assembly 2. The first slicing assembly 1 includes a fine-tuning bolt 11, a first tool holder 12, and two first blades 13. The first tool holder 12 is used to be connected to a driving device so as to be driven by the driving device to rotate. Two relatively arranged first clamping grooves 121 are formed on the first tool holder 12. The extending direction of the first clamping grooves 121 is the same as the direction of the rotation axis of the first tool holder 12. The two first blades 13 are respectively detachably installed in the two first clamping grooves 121. A through adjusting through hole 122 is provided on the first tool holder 12. The first tool holder 12 includes two relatively arranged adjusting bolt holes 123. One ends of the two adjusting bolt holes 123 are respectively communicated with the adjusting through hole 122, and the other ends are respectively communicated with the two first clamping grooves 121. The adjusting bolt holes 123 are used for the fine-tuning bolt 11 to be threadedly connected, and the adjusting bolt is used to abut against the first blade 13 to adjust the relative position of the first blade 13 and the first clamping groove 121.

[0046] The second slicing component 2 includes a second tool holder 21 and two second blades 22. The second tool holder 21 is used to be connected to a driving device so as to be driven by the driving device to rotate. The rotation direction of the second tool holder 21 is opposite to that of the first tool holder 12. Two relatively arranged second card slots 211 are formed on the second tool holder 21. The extending direction of the second card slots 211 is the same as the direction of the rotation axis of the second tool holder 21. The two second blades 22 are respectively detachably installed in the two second card slots 211. Among them, the cutting knife 101 includes a cutting state. In the cutting state, one side of the first blade 13 away from the first tool holder 12 abuts against one side of the second blade 22 away from the second tool holder 21 to cut off the material package.

[0047] Through the above technical solution, compared with the existing related technologies, the present application designs a brand-new cutting knife 101. The provided adjusting bolt holes 123 and fine-tuning bolts 11 can adjust the position of the first blade 13 relative to the second blade 22, so that the fitting clearance between the first blade 13 and the second blade 22 can reach a better condition, thereby ensuring that the fitting accuracy of the two can meet the production requirements. It can not only effectively ensure that the first blade 13 and the second blade 22 can reliably cut the strip-shaped packaging bag to improve production efficiency, but also effectively reduce the cutting noise and at the same time reduce equipment wear.

[0048] In the above technical solution, it should be noted that, first, there are various implementation manners for the first blade 13 to be installed in the first card slot 121. For example, it can be in the form of a snap (that is, a clamping block is provided on the first blade 13, and a corresponding card slot is provided in the second card slot 211, and the first blade 13 is detachably installed by clamping the clamping block in the card slot), or in the form of a bolt fastener (refer to the implementation manner of the installation bolt hole 127 and the fastening bolt in the following text), or in the form of a pin shaft (that is, an installation hole is provided on the first blade 13, which can be a through hole or a blind hole. At the same time, a corresponding installation through hole is formed on the first tool holder 12, and the first blade 13 is detachably installed by passing a pin shaft through the installation hole and the installation through hole). The present application does not make specific limitations on this. Similarly, there are also various implementation manners for the second blade 22 to be installed in the second card slot 211, which will not be elaborated here.

[0049] Second, the principle of the fine-tuning bolt 11 of the present application for adjusting the fitting clearance between the first blade 13 and the second blade 22 is as follows: Since the second blade 22 is installed in the second card slot 211, its relative position can be regarded as fixed. By turning the fine-tuning bolt 11, the fine-tuning bolt 11 abuts against the first blade 13 (during the fine-tuning process, the fixing structure of the first blade 13, such as the fastening bolt described below, can be slightly loosened to facilitate more convenient adjustment of the position of the first blade 13) and pushes the first blade 13 to make a small movement towards the second blade 22, thereby realizing the fine adjustment of the fitting clearance between the first blade 13 and the second blade 22.

[0050] Third, since the cutter 101 provided in the present application has two first blades 13 and two second blades 22, and the two first blades 13 and the two second blades 22 are respectively arranged oppositely, in this way, during the process of the first tool holder 12 or the second tool holder 21 rotating one week, two cutting states will be formed, which is also beneficial to improving the working efficiency of the cutter 101 of the present application for cutting the material package.

[0051] Fourth, the rotation directions of the first tool holder 12 and the second tool holder 21 of the present application are opposite. In this way, in the cutting state, the corresponding first blade 13 and the second blade 22 can rotate in opposite directions to the position where they contact each other, so that the strip-shaped packaging bag can be cut reliably and stably, which is beneficial to ensuring the cutting effect and avoiding the problem of unable to cut.

[0052] In an embodiment of the present application, as Figure 1 、 Figure 4 and Figure 5 shown, the two adjusting through holes 122 of the present application can be set to two, the two adjusting through holes 122 are arranged at intervals, the adjusting bolt holes 123 are set to four in pairs, two adjusting bolt holes 123 are arranged in one of the two adjusting through holes 122, and the other two adjusting bolt holes 123 are arranged in the other of the two adjusting through holes 122.

[0053] In this way, first, the two adjusting bolt holes 123 provided can act on the first blade 13 simultaneously from two different positions, so that the first blade 13 can be reliably and stably ensured to move smoothly towards the second blade 22, and the fitting clearance between the first blade 13 and the second blade 22 can be ensured to have a relatively uniform thickness to adapt to the adjustment of the cutting operation of the packaging bag.

[0054] Second, by respectively arranging two adjusting bolt holes 123 in the two adjusting through holes 122 arranged at intervals, it is not only convenient for the operator to operate, but also beneficial to reducing the structural influence on the first tool holder 12 caused by opening the adjusting through holes 122, which is beneficial to ensuring the structural strength of the first tool holder 12 to adapt to the cutting operation requirements of cutting the packaging bag.

[0055] It is understandable that the distance between the two adjustment through holes 122 of the present application can be adjusted according to the actual situation. At the same time, the position of the adjustment bolt hole 123 in the adjustment through hole 122 can also be adjusted according to the actual situation. For example, the adjustment bolt hole 123 can be in the middle of the corresponding adjustment through hole 122, and the present application does not make specific limitations on this.

[0056] In an embodiment of the present application, as Figure 1 、 Figure 4 and Figure 5 shown, three mounting bolt holes 127 arranged at intervals can also be formed on the first tool holder 12 of the present application. The mounting bolt holes 127 extend in the same direction as the adjustment through holes 122. One end of the mounting bolt hole 127 communicates with the first card slot 121, and the other end of the mounting bolt hole 127 is used to communicate with the external environment. Two of the three mounting bolt holes 127 are arranged on both sides of the two adjustment through holes 122, and one of the three mounting bolt holes 127 is arranged between the two adjustment through holes 122; the first slicing assembly 1 further includes a fastening bolt (not shown) adapted to the mounting bolt hole 127. The mounting bolt hole 127 is used for the connection of the fastening bolt, and the fastening bolt is used to abut against the first blade 13 so that the first blade 13 can be detachably received in the first card slot 121.

[0057] First, the installation of the first blade 13 is realized by means of the mounting bolt hole 127 and the fastening bolt, which is not only beneficial to the quick disassembly and assembly of the first blade 13, but also beneficial to the fine adjustment of the fitting clearance between the first blade 13 and the second blade 22. For example, when the fitting clearance between the first blade 13 and the second blade 22 needs to be finely adjusted, the fastening bolt can be slightly loosened, but still maintain a certain locking effect, and then the fitting clearance between the first blade 13 and the second blade 22 can be adjusted by the fine adjustment bolt.

[0058] Second, through the three mounting bolt holes 127 and the two adjustment through holes 122 arranged in this way, it is not only beneficial to avoid interference between the fastening bolt and the fine adjustment bolt, but also beneficial to ensure the structural strength and stress state of the first tool holder 12 when installing and adjusting the first blade 13.

[0059] In the existing related technologies, for example, taking the Chinese patent document with the publication number CN109733697A (a high-speed bag-packing machine) as an example, it uses two mutually meshing cutting knives to achieve the cutting operation of strip-shaped packaging bags. However, in the actual application process, the problem that the strip-shaped packaging bags cannot be cut often occurs with the two mutually meshing cutting knives. After investigation, the applicant found that because both cutting knives have serrated knife heads, during the cutting process, the cutting process of the two cutting knives only occurs when the two cutting knives jointly contact the strip-shaped packaging bag. Since the strip-shaped packaging bag is flexible, when the two cutting knives jointly contact the strip-shaped packaging bag, the two sides of the strip-shaped packaging bag in contact with the cutting knives may naturally fall under the action of gravity, resulting in the two cutting knives being unable to form sufficient clamping force on the strip-shaped packaging bag, and thus unable to cut the strip-shaped packaging bag.

[0060] In view of this, in an embodiment of the present application, as Figures 4 to 6 shown, the first blade 13 of the present application may include a blade body 131 and a toothed knife head 132 connected to each other. The blade body 131 is formed into a plate-like structure and is used for detachably mounting in the first card slot 121. The toothed knife head 132 protrudes from the first tool holder 12; the second blade 22 is formed into a plate-like structure and is used for detachably mounting in the second card slot 211, and a part of the second blade 22 protrudes from the second tool holder 21; in the cutting state, the toothed knife head 132 abuts against the second blade 22 to cut the material package.

[0061] In this way, during the process of the first blade 13 and the second blade 22 of the present application cutting the material package, the two side parts of the strip-shaped packaging bag located on both sides of the first cutting knife 101 are supported by the end face of the second cutting knife 101 and remain in a flat state, so that the first blade 13 and the second blade 22 can form sufficient clamping force on the strip-shaped packaging bag, and thus can effectively cut the strip-shaped packaging bag.

[0062] In an embodiment of the present application, as Figure 6 and Figure 7 shown, the toothed knife head 132 of the present application may include a first end 1321 and a second end 1322 arranged oppositely. The first end 1321 is connected to the blade body 131, and the second end 1322 is formed into a zigzag structure, and all the endpoints of the zigzag corresponding to the zigzag structure are respectively located on two parallel lines.

[0063] By arranging the toothed knife head 132 in this way, the first blade 13 and the second blade 22 can form a regular and uniformly stressed clamping state on the strip-shaped packaging bag, so that the first blade 13 and the second blade 22 can stably and reliably clamp the strip-shaped packaging bag.

[0064] In an embodiment of the present application, as Figure 4 and Figure 5As shown in the figure, at least two mounting bolt holes 127 spaced apart from each other may be formed on the first tool holder 12 of the present application. The mounting bolt holes 127 extend in the same direction as the adjustment through holes 122. One end of the mounting bolt holes 127 communicates with the first card slot 121, and the other end of the mounting bolt holes 127 is used for communicating with the external environment. The first slicing assembly 1 further includes fastening bolts adapted to the mounting bolt holes 127. The mounting bolt holes 127 are used for connecting the fastening bolts, and the fastening bolts are used to abut against the first blade 13 so that the first blade 13 is detachably received in the first card slot 121.

[0065] In this way, the stable installation of the first blade 13 can be realized through the mounting bolt holes 127 arranged in this way, which is not only beneficial to the quick disassembly and assembly of the first blade 13, but also beneficial to the fine adjustment of the clearance between the first blade 13 and the second blade 22.

[0066] In an embodiment of the present application, as Figure 8 shown, the cutter 101 of the present application may further include a driving member 3. The driving member 3 includes a driving motor 31, and a first gear 32 and a second gear 33 that mesh with each other and have a tooth ratio of 1:1. The output end of the driving motor 31 is connected to the first tool holder 12 to drive the first tool holder 12 to rotate. The first gear 32 is sleeved on the output end of the driving motor 31, and the second gear 33 is sleeved on the second tool holder 21, so that the first tool holder 12 and the second tool holder 21 rotate in the opposite directions at the same speed; alternatively, the output end of the driving motor 31 is connected to the second tool holder 21 to drive the second tool holder 21 to rotate. The first gear 32 is sleeved on the output end of the driving motor 31, and the second gear 33 is sleeved on the first tool holder 12, so that the first tool holder 12 and the second tool holder 21 rotate in the opposite directions at the same speed.

[0067] In this way, through the driving member 3 arranged in this way, not only can the first tool holder 12 and the second tool holder 21 be driven simultaneously to save equipment space and reduce energy consumption, but also the first tool holder 12 and the second tool holder 21 can rotate in the opposite directions at the same speed. In this way, in the cutting state, the corresponding first blade 13 and the second blade 22 can rotate to the position where they are in contact with each other in the opposite directions, so that the strip-shaped packaging bag can be cut reliably and stably, which is beneficial to ensuring the cutting effect and avoiding the problem of inability to cut.

[0068] In an embodiment of the present application, as Figure 8 shown, the cutter 101 of the present application may further include a first mounting plate 41 and a second mounting plate 42 arranged at intervals. Both ends of the first tool holder 12 are rotatably mounted on the first mounting plate 41 and the second mounting plate 42 respectively. Both ends of the second tool holder 21 are rotatably mounted on the first mounting plate 41 and the second mounting plate 42 respectively.

[0069] In this way, through the first mounting plate 41 and the second mounting plate 42 arranged in this manner, the first tool holder 12 and the second tool holder 21 can be stably and reliably mounted, so as to be able to stably and reliably cut the strip-shaped packaging bag.

[0070] In an embodiment of the present application, as Figure 8 shown, the first tool holder 12 of the present application may include a first holder body 124, a first rotating column 125 and a first connecting rod 126. The first rotating column 125 is rotatably mounted on the first mounting plate 41. Two ends of the first holder body 124 are respectively connected to the first rotating column 125 and the first connecting rod 126. One end of the first connecting rod 126 far from the first holder body 124 penetrates through the second mounting plate 42 and is used for connecting with a driving device. The adjusting through hole 122, the adjusting bolt hole 123 and the first clamping groove 121 are respectively formed on the first holder body 124; the second tool holder 21 includes a second holder body 212, a second rotating column 213 and a second connecting rod 214.
