Detailed implementation mode

[0037] Figure 1 It is a side view of an existing rotary cutting tool when it does not perform a cutting operation. Figure 2 It is Figure 1 The front view of the rotary cutting tool when it does not perform a cutting operation. Refer to Figure 1 and Figure 2 The rotary cutting tool may include: a first tool assembly 11 and a second tool assembly 12. Among them, the first tool assembly 11 may include: a first rotating shaft 111, a first tool support 112, a tooth part 113, and a first driving part (not shown). The second tool assembly 12 may include: a second rotating shaft 121, a second tool support 122, a tooth - mating part 123, and a second driving part (not shown).

[0038] Among them, the first driving part is adapted to drive the first rotating shaft 111 to rotate. The first tool support 112 is arranged around the first rotating shaft 111 and fixes the tooth part 113, so that the tooth part 113 can be fixed on the first rotating shaft 111 and rotate with the rotation of the first rotating shaft 111. The second driving part is adapted to drive the second rotating shaft 121 to rotate. The second tool support 122 is arranged around the second rotating shaft 121 and fixes the tooth - mating part 123, so that the tooth - mating part 123 can be fixed on the second rotating shaft 121 and rotate with the rotation of the second rotating shaft 121.

[0039] The first rotating shaft 111 and the second rotating shaft 121 rotate towards each other. At a certain moment, the tooth part 113 and the tooth - mating part 123 will synchronously rotate to the opposite sides of the cutting area between adjacent seasoning packets. At this time, the tooth part 113 and the tooth - mating part 123 will simultaneously apply pressure towards each other to the cutting area between adjacent seasoning packets, so that the distance between the tooth part 113 and the tooth - mating part 123 gradually decreases until they are in close contact, and the adjacent seasoning packets are separated.

[0040] During the process of performing the cutting operation, since the tooth part 113 and the tooth - mating part 123 need to be in close contact to achieve cutting, it will cause a certain amount of wear to the tooth part 113 and the tooth - mating part 123.

[0041] In practical applications, the speed of each bag-feeding machine can reach 250 bags per minute. The workload of a rotary cutting tool per day is approximately 330,000 times. If a rotary cutting tool works 26 days per month, then a rotary cutting tool needs to perform 8.58 million cutting operations per month, resulting in a relatively short service life of the cutting blade composed of the cutter tooth part 113 and the cutter tooth mating part 123. It needs to be scrapped and replaced every two months (17.16 million times), which not only affects the cutting efficiency but also increases the cutting cost.

[0042] To solve this problem, the present utility model provides a rotary cutting tool. By using this rotary cutting tool and providing a heating part capable of heating the cutter tooth part or the cutter tooth mating part, the existing cold cutting of the rotary cutting tool can be changed to hot cutting. Furthermore, during the cutting operation, the contact between the cutter tooth part and the cutter tooth mating part can be minimized, thereby reducing the wear of the cutting blade, increasing the service life of the cutting blade, ultimately improving the cutting efficiency, and reducing the cutting cost.

[0043] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following specifically describes the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0044] The embodiment of the present utility model provides a rotary cutting tool, which may include: a base, a first tool assembly, and a second tool assembly. Among them:

[0045] The first tool assembly and the second tool assembly are rotatably fixed on the base;

[0046] The first tool assembly includes a cutter tooth part, and the second tool assembly includes a cutter tooth mating part; by rotating the first tool assembly and the second tool assembly, the cutter tooth part and the cutter tooth mating part are matched to perform a cutting operation;

[0047] Among them, at least one of the first tool assembly and the second tool assembly includes: a heating part; the heating part is used to heat the cutter tooth part or the cutter tooth mating part.

[0048] In specific implementation, the heating part can be provided only in the first tool assembly, or only in the second tool assembly, or on both the first tool assembly and the second tool assembly.

[0049] By heating at least one of the cutter tooth part or the cutter tooth mating part, while realizing cutting, the contact between the cutter tooth part and the cutter tooth mating part can be minimized, thereby reducing the wear of the cutting blade and increasing the service life of the cutting blade.

[0050] It can be understood that by providing a heating part only on one of the first tool assembly and the second tool assembly, compared with the existing cold-cut rotary cutting tool, the contact between the tool tooth part and the tool tooth mating part can also be reduced, thereby increasing the tool blade life.

[0051] In the following embodiments, for the sake of convenience of description, the heating part provided in the first tool assembly is taken as the first heating part, and the heating part provided in the second tool assembly is taken as the second heating part.

The second heating part can heat the blade tooth matching part, and under the tightening action of the second tool support on the blade tooth matching part, the second heating part can be stably located between the blade tooth matching part and the second rotating shaft.

The first rotating shaft and the second rotating shaft rotate toward each other, and at a certain moment, the blade tooth portion and the blade tooth matching portion will synchronously rotate to the opposite sides of the area to be cut between adjacent seasoning packets. At this time, the blade tooth portion and the blade tooth matching portion will simultaneously apply pressure to the area to be cut between adjacent seasoning packets in opposite directions, so that the distance between the blade tooth portion and the blade tooth matching portion gradually decreases. Under the action of at least one of the first heating portion and the second heating portion, the blade tooth portion and the blade tooth matching portion do not need to be in close contact, and the adjacent seasoning packets can be separated.

[0059] In a specific implementation, the first tool assembly may include only one tooth portion, or may include two or more tooth portions. When there are more than two tooth portions, a first heating portion may be provided under each tooth portion, or a first heating portion may be provided under only some of the tooth portions. The structure of the first tool support may vary according to the number of tooth portions, as long as the tooth portions and the first heating portion can be fixed on the first rotating shaft.

[0060] In a specific implementation, the second tool assembly may include only one blade tooth matching portion, or may include two or more blade tooth matching portions, and the number of blade tooth matching portions is consistent with the number of blade tooth portions and is arranged one by one.

[0085] Figure 5 It is a schematic cross-sectional view of a heating part along the direction of the rotating shaft of the tool assembly in an embodiment of the present invention. Referring to Figure 5 , the heating part 50 may include: a heat conducting base 51, a heating element 52 located within the heat conducting base 51, and a controller 55; the heat conducting base 51 is located below the cutter tooth part or the cutter tooth mating part; the heating element 52 is used to heat the cutter tooth part or the cutter tooth mating part; the controller 55 is used to control the operation of the heating element 52.

[0086] The heat conducting base 51 can be a base capable of conducting heat, such as metal. Under the control of the controller 55, the heating element 52 generates heat, which is transmitted to the upper cutter tooth part or the cutter tooth mating part through the heat conducting base 51. Specifically:

[0087] When the heat conducting base 51 is provided below the cutter tooth part, the shape of the heat conducting base 51 along the axial direction of the first rotating shaft is substantially the same as the shape of the surface of the cutter tooth part facing the heat conducting base. The dimension of the heat conducting base 51 along the direction perpendicular to the first rotating shaft (i.e., the thickness of the heat conducting base) can be set according to the size of the gap between the cutter tooth part and the first rotating shaft in the tool assembly where it is located.

[0088] When the heat conducting base 51 is arranged below the cutter tooth engaging portion, the shape of the heat conducting base 51 in the axial direction of the second rotating shaft is substantially the same as the shape of the surface of the cutter tooth engaging portion facing the heat conducting base 51. The dimension of the heat conducting base 51 in the direction perpendicular to the second rotating shaft (i.e., the thickness of the heat conducting base) can be set according to the size of the gap between the cutter tooth engaging portion and the second rotating shaft.

[0089] For example, when both the cutter tooth portion and the cutter tooth engaging portion are cuboids, the shape of the heat conducting base 51 can be set as a cuboid.

[0090] In a specific implementation, the heating element 52 can be arranged in the heat conducting base 51 in various ways.

[0091] In one embodiment, a first blind hole 511 can be arranged in the heat conducting base 51, and the heating element 52 can be inserted into the heat conducting base 51 from the opening of the first blind hole 511. By setting the dimension of the first blind hole 511, the heating element 52 can be stably located in the first blind hole 511.

[0092] In some embodiments, the heating portion 50 can also include a plurality of first fixing members 53, and the plurality of first fixing members 53 are distributed along the axial direction of the rotating shaft. Each first fixing member 53 can be inserted into the first blind hole 511 from one side of the heat conducting base 51, and one end of the first fixing member 53 abuts against the heating element 52, so that the heating element 52 can be more stably located in the first blind hole 511.

[0093] In a specific implementation, the insertion position of the first fixing member 53 on the heat conducting base 51 can be below the tool holder, that is, the position on the heat conducting base 51 not covered by the radial structure of the tool holder, thereby reducing the influence on the fixing effect of the tool holder.

[0094] In a specific implementation, the heating element 52 can be realized in various ways.

[0095] In one embodiment, the heating element 52 can be realized by an electric heating rod. The electric heating rod has a heating body and a signal wire. The shape of the heating body is the same as the shape of the first blind hole 511, and the dimension of the heating body can match the dimension of the first blind hole 511. The heating body can be arranged in the heat conducting base 51, and the signal wire can be led out from the opening of the heat conducting base 51 and connected to the controller 55. The controller 55 supplies power to the heating body through the signal wire, so that the heating body can generate heat.

[0096] In another embodiment of the present invention, the heating portion 50 can further include: a temperature detection member 54 located in the heat conducting base 51. The temperature detection member 54 can detect the temperature of the heat conducting base 51 after being heated and send the detection result to the controller 55.

[0097] Specifically, a second blind hole 512 can be provided in the heat conduction base 51, and the temperature detection member 54 can be inserted into the heat conduction base 51 from the opening of the second blind hole 512. By setting the size of the second blind hole 512, the temperature detection member 54 can be stably located within the second blind hole 512.

[0098] In some embodiments, the heating portion 50 may also include a plurality of second fixing members 532, which are distributed along the axial direction of the rotating shaft. Each second fixing member 532 can be inserted into the interior of the second blind hole 512 from one side of the heat conduction base 51, and one end of the second fixing member 532 abuts against the temperature detection member 54, so that the temperature detection member 54 can be more stably located within the second blind hole 512.

[0099] In a specific implementation, the insertion position of the second fixing member 532 on the heat conduction base 51 can be below the tool holder, that is, the position on the heat conduction base 51 not covered by the radial structure of the tool holder, thereby reducing the influence on the fixing effect of the tool holder.

[0100] In a specific implementation, the temperature detection member 54 can be implemented by a temperature sensor. Specifically, the temperature sensor may include a sensing portion 541, a housing 542, and a signal line 543. The housing 542 can connect the sensing portion 541 and the signal line 543 and has a certain mechanical strength. The second fixing member 532 can be inserted into the second blind hole 512 at a position corresponding to the housing 542 to fix the temperature detection member 54, thereby avoiding damage to the temperature detection member 54 while fixing the temperature detection member 54.

[0101] In a specific implementation, taking the first rotating shaft 312 as an example, four copper rings 551 can be provided on one side of the first rotating shaft 312 not covered by the first tool holder. Each copper ring 551 is respectively connected to a signal line, including two signal lines of the temperature detection member 54 and two signal lines of the heating member 52. Then, the corresponding pins of the controller 55 are connected to the copper rings 551 through the brush 552, so as to realize the connection between the controller 55, the temperature detection member 54, and the heating member 52.

[0102] In a specific implementation, the controller 55 can control the operation of the heating member 52 based on the detection result of the temperature detection member 54. For example, when the temperature of the heating member 52 is relatively high, the controller 55 can control the heating member 52 to stop heating. When the temperature of the heating member 52 is relatively low, the controller 55 can control the heating member 52 to continue heating until a set temperature value is reached.

[0103] It should be noted that, with reference to the description of the heating portion above Figure 5 each first heating portion of the first tool assembly and each second heating portion of the second tool assembly can be implemented, and no further examples will be given here.

[0104] Figure 6 This is a schematic diagram of the positions of the cutter tooth part and the heating part in the radial direction of the first rotating shaft in an embodiment of the present utility model. Figure 7 This is a schematic diagram of the positions of the cutter tooth part and the heating part in the radial direction of the first rotating shaft in another embodiment of the present utility model.

[0105] Referring to Figure 6 and Figure 7 , the bottom surface size of the cutter tooth part 61 can be smaller than the top surface size of the heating part 51. The bottom surface size of the cutter tooth part 61 can also be equal to the top surface size of the heating part 51 (as shown in Figure 3 ).

[0106] Referring to Figure 6 , the bottom surface of the cutter tooth part 61 and the top surface of the heating part 51 can both be flat surfaces. In this way, the bottom surface of the cutter tooth part 61 can be located on the top surface of the heating part 51.

[0107] In some embodiments, referring to Figure 7 , a groove can be provided on the top surface of the heating part 51, and the size of the groove matches the size of the bottom of the cutter tooth part 61. At this time, the bottom of the cutter tooth part 61 can be partially located in the groove, thereby further increasing the stability of the cutter tooth part 61.

[0108] Similarly, the bottom surface of the cutter tooth matching part can be directly located on the flat top surface of the heating part, or the stability of the cutter tooth matching part can be increased by providing a groove on the top surface of the heating part.

[0109] By adopting the solution of the present utility model, by providing a heating part to heat at least one of the cutter tooth part and the cutter tooth matching part, the wear of the blade during the cutting process can be reduced, thereby improving the blade life.

[0110] An embodiment of the present utility model also provides a bag feeding machine, and the bag feeding machine can include the rotary cutting tool described in the above embodiment.

[0111] In specific implementation, the bag feeding machine can further include: a bag feeding machine body. The bag feeding machine body can be used to receive a plurality of sequentially connected objects to be cut (such as the seasoning packets of instant noodles), and place the cutting area between adjacent seasoning packets between the first tool assembly and the second tool assembly, and the cutter tooth part and the cutter tooth matching part perform a cutting operation on the cutting area.

[0112] In specific implementation, the objects to be cut can be sequentially placed between the first tool assembly and the second tool assembly from top to bottom, and the cutter tooth structure on the tool body is aligned with the cutting area, so that the corresponding driving part drives the tool assembly to act, realizing the cutting of continuous objects to be cut.

[0113] After statistics, the service life of the improved rotary cutting tool in this utility model has increased to half a year. Calculated according to the average working time of 150 days in half a year, the total number of working times of the rotary cutting tool can reach 50 million times, the increased life is 2.91 times, the equipment maintenance time can be reduced, and the demand for spare parts can be reduced by 60%.

[0114] Although the present utility model is disclosed as above, the present utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the scope defined by the claims.
