Description

Technical Field

[0002] Trimming machines are commonly used equipment in the die-casting industry to cut and trim die-cast products to achieve the required size and shape. The trimming machine is equipped with a mold. During the mold manufacturing process, the mold structure design often needs to meet the diversity and complexity of product design. For example, the core-pulling structure can be a movable core component built into the mold. It can extend and retract according to the functional requirements of the product design to ensure that the product can be smoothly removed from the mold when it is formed in the mold and to maintain the integrity of the design.

[0003] In the existing control methods of edge cutting machines, the extension and retraction of the core-pulling structure mainly occurs before and after mold locking or mold opening.

[0040] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present application with unnecessary detail.

[0041] It should be understood that, when used in this application specification and the appended claims, the term "comprising" indicates the presence of the described features, integrals, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or a collection thereof.

[0042] It should also be understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0043] As used in this application specification and the appended claims, the term "if" may be interpreted, depending on the context, as "when," "once," "in response to determination," or "in response to detection." Similarly, the phrase "if determined" or "if detected [the described condition or event]" may be interpreted, depending on the context, as meaning "once determined," "in response to determination," "once detected [the described condition or event]," or "in response to detection [the described condition or event]."

[0044] Furthermore, in the description of this application and the appended claims, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0045] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0046] It can be argued that traditional edge cutting machines have a limited number of core-pulling structures, with a maximum of eight such structures. Moreover, edge cutting machines on the market mainly perform the extension and retraction of the core-pulling structure before or after mold locking and before or after mold opening. They cannot perform the extension and retraction of the core-pulling structure during mold locking or mold opening, and therefore cannot meet the production needs of complex parts or the needs of future product upgrades.

[0047] Based on this, the present application provides a control method for an edge trimming machine. By reserving a sufficient number of core-pulling groups and flexibly configuring the timing of the core-pulling structure's extension and retraction actions according to needs, it can meet the production needs of complex parts and the needs of future product upgrades, improve the production flexibility of the program and the utilization rate of the equipment, reduce the cost of later modification, and enhance market competitiveness.

[0048] Figure 1 This is a flowchart illustrating a control method for an edge trimming machine according to an embodiment of this application. It is provided as an example and not as a limitation. This method can be applied to an edge trimming machine equipped with a mold, such as... Figure 1 As shown, the method includes:

[0049] S101. Obtain the core-pulling control information input by the user.

[0050] The core-pulling control information includes first core-pulling sequence data and second core-pulling sequence data. The first core-pulling sequence data is used to characterize the order in which at least a portion of the core-pulling structure of the mold is inserted into a specified internal position, and the second core-pulling sequence data is used to characterize the order in which at least a portion of the core-pulling structure is pulled out from the specified internal position.

[0051] It is understandable that the trimming machine is equipped with a mold. During the mold manufacturing process, the structural design of the mold often needs to meet the diversity and complexity of the product design. For example, in some designs, the mold needs to include sliders, angled ejectors and other internal pulling parts. These parts need to achieve specific functions through core pulling action. Therefore, these parts can be collectively referred to as core pulling structure. In other words, core pulling structure can refer to a movable core component built into the mold. It can perform telescopic actions according to the functional requirements of the product design, which can ensure that the product can be smoothly ejected from the mold when it is formed in the mold and maintain the integrity of the design.

[0052] Furthermore, different molds use different numbers of core-pulling structures. For example, users can flexibly configure the number of core-pulling structures needed and the sequence of their extension and retraction actions on the engineering configuration page of the edge-cutting machine's touchscreen. Users can input core-pulling control information on the engineering configuration page according to the structural requirements of the mold and product. This control information can include first core-pulling sequence data and second core-pulling sequence data. The first core-pulling sequence data can at least characterize the order in which at least some of the core-pulling structures of the mold are inserted into designated internal positions. The specific content of the first and second core-pulling sequence data is not limited, as long as it can characterize the sequence of core-pulling actions of at least some of the core-pulling structures. At least some of the core-pulling structures can refer to the core-pulling structures selected by the user in this instance.

[0053] S102. During the process of controlling the mold to perform the mold-locking operation, and after the mold has completed the mold-locking operation, at least part of the core-pulling structure is controlled to be inserted into the designated internal position based on the first core-pulling sequence data.

[0054] The internal designated position can be understood as the position that each core-pulling structure needs to move from its original position to. The internal designated position corresponding to each core-pulling structure can be the same or different. The specific content can be configured in advance according to product requirements.

[0055] After obtaining the core-pulling control information input by the user, the edge-cutting machine can control at least some of the core-pulling structures to be inserted into the designated internal position based on the first core-pulling sequence data. The specific timing for controlling the core-pulling structure can include during the process of controlling the mold to perform the mold-locking operation, and after the mold has completed the mold-locking operation. Different core-pulling structures can correspond to different control timings.

[0056] As a feasible implementation method, the control timing of the core-pulling structure corresponding to the first core-pulling sequence data that is before the preset sort number can be specified as being during the mold-locking operation, and the control timing of the core-pulling structure corresponding to the first core-pulling sequence data that is after the mold-locking operation is completed. The content of the preset sort number is not limited. For example, during the mold-locking operation, the first three core-pulling structures in the first core-pulling sequence data can be controlled to be inserted into the specified internal position in sequence. Then, after the mold-locking operation is completed, the core-pulling structures after the first three in the first core-pulling sequence data can be controlled to be inserted into the specified internal position in sequence, thereby completing the insertion and extension action of multiple core-pulling structures.

[0057] It should be noted that during the mold-locking operation, controlling the first three core-pulling structures in the first core-pulling sequence data to insert into their designated positions sequentially can be understood as simultaneously controlling the mold-locking operation while simultaneously controlling the first three core-pulling structures in the first core-pulling sequence data to insert into their designated positions. Alternatively, if the mold-locking operation needs to last for a certain period, the mold can be controlled to begin the mold-locking operation first. Then, under specific conditions, the mold can be controlled to pause the mold-locking operation while simultaneously controlling the first three core-pulling structures in the first core-pulling sequence data to insert into their designated positions. The mold can then continue the mold-locking operation until it is complete. The specific details of these specific conditions will not be elaborated further here.

[0058] As a feasible implementation method, users can also specify the control timing of the core-pulling structure through core-pulling control information or other means. The specific methods of specification will not be elaborated here, as long as at least part of the core-pulling structure can be controlled to complete the insertion and extension action.

[0059] S103. If the edge trimming machine is detected to have completed the edge trimming operation, then before the mold is controlled to perform the mold opening operation, and during the mold opening operation, at least part of the core pulling structure is controlled to be pulled out from the specified internal position based on the second core pulling sequence data.

[0060] Understandably, after controlling the mold to complete the mold-locking operation and controlling the multiple core-pulling structures to complete the insertion and extension actions, the trimming machine can start the trimming operation on the product. After the trimming machine completes the trimming operation, it is necessary to control the mold to perform the mold-opening operation and control the multiple core-pulling structures to complete the shrinking action in order to achieve the demolding of the product.

[0061] Specifically, the timing for controlling multiple core-pulling structures to complete the shrinking action can be either before or during the mold opening operation. Different core-pulling structures can correspond to different control timings. The process of controlling the shrinking action of the core-pulling structure can be similar to the process of controlling the insertion and extension action of the core-pulling structure described above.

[0062] For example, before the mold is opened, the top three core-pulling structures in the second core-pulling sequence data can be pulled out from their designated internal positions in sequence. For example, the core-pulling structures can retract from their designated internal positions to their original positions. Then, the mold is opened. During the mold opening process, the core-pulling structures after the top three in the second core-pulling sequence data are pulled out from their designated internal positions in sequence, thereby completing the retraction action of multiple core-pulling structures.

[0063] It should be noted that during the mold opening operation, controlling the core-pulling structures after the first three in the second core-pulling sequence data to be pulled out from their designated internal positions sequentially can be understood as simultaneously controlling the mold opening operation while controlling the core-pulling structures after the first three in the second core-pulling sequence data to be pulled out from their designated internal positions sequentially. Alternatively, if the mold opening operation needs to last for a certain period of time, the mold can be controlled to start the mold opening operation first, and then, under certain conditions, the mold opening operation can be paused while the core-pulling structures after the first three in the second core-pulling sequence data are pulled out from their designated internal positions sequentially. The mold can then continue the mold opening operation until it is complete. The specific details of these specific conditions will not be elaborated further here.

[0064] This embodiment provides a control method for an edge-trimming machine, which acquires core-pulling control information input by a user. The core-pulling control information includes first core-pulling sequence data and second core-pulling sequence data. The first core-pulling sequence data at least characterizes the order in which at least a portion of the core-pulling structure of the mold is inserted into a designated internal position, and the second core-pulling sequence data at least characterizes the order in which at least a portion of the core-pulling structure is withdrawn from the designated internal position. During the mold-locking operation and after the mold has completed the locking operation, at least a portion of the core-pulling structure is controlled to be inserted into the designated internal position based on the first core-pulling sequence data. If the edge-trimming machine is detected to have completed the edge-pulling operation, at least a portion of the core-pulling structure is controlled to be withdrawn from the designated internal position based on the second core-pulling sequence data before and during the mold-opening operation. Using this method, by acquiring the core-pulling control information input by the user, it is possible to control at least part of the core-pulling structure to be inserted into a designated internal position during and after the mold locking operation, and to control at least part of the core-pulling structure to be pulled out from a designated internal position before and during the mold opening operation. This enriches the control methods of existing edge-cutting machines, and enables flexible configuration of the timing of the core-pulling structure's extension and retraction actions according to product requirements, thus meeting the production needs of complex parts and the needs of future product upgrades.

[0065] Figure 2 This is a flowchart illustrating a control method for a trimming machine according to another embodiment of this application. In this embodiment, the first core-pulling sequence data includes: a first sorting value corresponding to each group of core-pulling structures in all core-pulling structures of the mold, and a second sorting value corresponding to the mold-locking operation. The first sorting value is a natural number, and the second sorting value is a positive integer. The first sorting value and the second sorting value are not equal. Further optimization of controlling at least some core-pulling structures to insert into designated internal positions based on the first core-pulling sequence data during and after the mold's mold-locking operation is as follows: determining a first target value and a second target value among multiple first sorting values, wherein the first target value is less than the second sorting value, the second target value is greater than the second sorting value, and the first target value is a positive integer; controlling the core-pulling structure corresponding to the first target value in the mold to insert into the designated internal position during the mold-locking operation; and controlling the core-pulling structure corresponding to the second target value in the mold to insert into the designated internal position according to the second target value in ascending order. Figure 2 As shown, the method includes:

[0066] S201. Obtain the core-pulling control information input by the user.

[0067] S202. Determine the first target value and the second target value among multiple first sorted values.

[0068] Among them, the first target value is less than the second sorted value, the second target value is greater than the second sorted value, and the first target value is a positive integer.

[0069] In this embodiment, the specific content of the first core-pulling sequence data may include: a first sorting value corresponding to each group of core-pulling structures in all core-pulling structures of the mold, and a second sorting value corresponding to the mold-locking operation. The first sorting value is a natural number, and the second sorting value is a positive integer. The first sorting value and the second sorting value are not equal, that is, the insertion and extension action of the core-pulling structure can be before or after the mold-locking is in place. The mold-locking operation can be sorted together with the insertion and extension actions of all core-pulling structures to form the first core-pulling sequence data. The arrangement number corresponding to each group of core-pulling structures in all core-pulling structures of the mold can be the first sorting value, and the arrangement number corresponding to the mold-locking operation can be the second sorting value. The first sorting value is a natural number, and the second sorting value is a positive integer.

[0070] For example, in this embodiment, a sufficient number of core-pulling structure groups can be reserved in the edge-cutting machine program. For instance, the mold can be configured with 20 core-pulling structures, so that this embodiment can control the actions of the 20 core-pulling structures and solve the sequencing problem between the mold-locking and opening operations and the actions of the 20 core-pulling structures. For instance, the mold-locking operation can be sequenced together with the 20 core-pulling insertion operations, and the sequencing value can be from 0 to 20. The mold-opening sequencing value can be sequenced together with the 20 core-pulling extraction operations, and the sequencing value can be from 0 to 20.

[0071] Furthermore, when the first sorting value of a certain core-pulling structure is set to "0", it means that the core-pulling structure is not used, that is, there is no need to control the core-pulling structure to perform the insertion and extension action.

[0072] The first sorting value corresponding to different core-pulling structures can be the same or different. For example, when different core-pulling structures correspond to the same first sorting value, it can indicate that multiple sets of core-pulling structures can perform insertion and extension actions at the same time.

[0073] At the same time, the first sorting value and the second sorting value are not equal. That is, the arrangement number corresponding to each group of core-pulling structures cannot be the same as the arrangement number corresponding to the mold-locking operation. For example, when the second sorting value is "2", the first sorting value corresponding to other core-pulling structures can only be set to a value other than "2".

[0074] Specifically, the core-pulling structure can be controlled differently based on the magnitude of the first and second sorting values. For example, if the first sorting value is less than the second sorting value, the core-pulling structure corresponding to the first sorting value needs to perform the insertion and extension action before the mold-locking operation is in place. If the first sorting value is greater than the second sorting value, the core-pulling structure corresponding to the first sorting value needs to perform the insertion and extension action after the mold-locking operation is in place.

[0075] Therefore, after obtaining the first sorted values ​​of multiple core-pulling results and the second sorted values ​​corresponding to the mold-locking operation through the above steps, the first target value and the second target value among the multiple first sorted values ​​can be determined. The first target value is the first sorted value among the multiple first sorted values ​​that is less than the second sorted value, and the first target value is a positive integer; the second target value is the first sorted value among the multiple first sorted values ​​that is greater than the second sorted value. Subsequently, different controls can be applied to the multiple core-pulling structures based on the first target value and the second target value.

[0076] S203. During the process of controlling the mold to perform the mold-locking operation, the core-pulling structure corresponding to the first target value in the mold is controlled to be inserted into the specified internal position.

[0077] In some embodiments, during the process of controlling the mold to perform a mold-locking operation, controlling the core-pulling structure in the mold corresponding to the first target value to be inserted into a designated internal position includes:

[0078] During the process of controlling the mold to perform the mold-locking operation, it is detected whether the current position of the mold has reached the first set position;

[0079] If the current position of the mold is detected to have reached the first set position, then the core-pulling structure corresponding to the first target value in the mold is controlled to be inserted into the designated position inside according to the first target value in ascending order.

[0080] In a specific implementation, during the mold clamping operation, the real-time position of the mold can be detected by an electronic ruler to determine when to control the core-pulling structure corresponding to the first target value to be inserted into the designated internal position. The first set position can be a pre-set middle plate position. The core-pulling structure is only executed when the mold reaches the middle plate set position.

[0081] For example, when the first set position is set to 1145mm, and the corresponding sequence values ​​for mold locking operation, core pulling structure 1, and core pulling structure 2 are set to 2, 1, and 3, the control sequence of the edge trimming machine can include: when the mold reaches the middle plate position of 1145mm, control the core pulling structure 1 to insert into the internal designated position; when the mold completes the mold locking operation (i.e., the mold is closed in place), control the core pulling structure 2 to insert into the internal designated position.

[0082] S204. After detecting that the mold has completed the mold-locking operation, the core-pulling structure corresponding to the second target value is controlled to be inserted into the designated position inside the mold in order from small to large.

[0083] S205. If the edge trimming machine is detected to have completed the edge trimming operation, then before the mold is controlled to perform the mold opening operation, and during the mold opening operation, at least part of the core pulling structure is controlled to be pulled out from the internal designated position based on the second core pulling sequence data.

[0084] This embodiment provides a control method for a trimming machine. By using first core-pulling sequence data, including a first sorting value corresponding to each group of core-pulling structures in all core-pulling structures of the mold and a second sorting value corresponding to the mold-locking operation, and determining a first target value and a second target value among multiple first sorting values, it can provide an accurate data basis for subsequently controlling different core-pulling structures to be inserted into designated internal positions at different times. This enables flexible configuration of the timing of the core-pulling structure to perform the stretching action according to product requirements, further meeting the production needs of complex parts and the needs of future product upgrades.

[0085] Figure 3 This is a flowchart illustrating a control method for a trimming machine according to another embodiment of this application. In this embodiment, the second core-pulling sequence data includes: a third sorting value corresponding to each group of core-pulling structures in all core-pulling structures of the mold, and a fourth sorting value corresponding to the mold opening operation. The third sorting value is a natural number, and the fourth sorting value is a positive integer. The third sorting value and the fourth sorting value are not equal. The method of controlling at least some core-pulling structures to be extracted from a specified internal position based on the second core-pulling sequence data before and during the mold opening operation is further optimized as follows: determining a third target value and a fourth target value among multiple third sorting values, wherein the third target value is less than the fourth sorting value, the fourth target value is greater than the fourth sorting value, and the third target value is a positive integer; before controlling the mold to perform the mold opening operation, controlling the core-pulling structures corresponding to the third target values ​​in the mold to be extracted from the specified internal positions in ascending order of the third target values; during the mold opening operation, controlling the core-pulling structures corresponding to the fourth target values ​​in the mold to be extracted from the specified internal positions. Figure 3 As shown, the method includes:

[0086] S301. Obtain the core-pulling control information input by the user.

[0087] S302. During the process of controlling the mold to perform the mold-locking operation, and after the mold has completed the mold-locking operation, at least part of the core-pulling structure is controlled to be inserted into the designated internal position based on the first core-pulling sequence data.

[0088] S303. If the edge trimming machine is detected to have completed the edge trimming operation, then the third target value and the fourth target value among the multiple third sorting values ​​are determined.

[0089] Among them, the third target value is less than the fourth sorted value, the fourth target value is greater than the fourth sorted value, and the third target value is a positive integer.

[0090] In this embodiment, the specific content of the second core-pulling sequence data may include: a third sorting value corresponding to each group of core-pulling structures in all core-pulling structures of the mold, and a fourth sorting value corresponding to the mold opening operation. The third sorting value is a natural number, and the fourth sorting value is a positive integer. The third sorting value and the fourth sorting value are not equal, that is, the extension and retraction action of the core-pulling structure can be before or after the mold opening is completed. The mold opening operation can be sorted together with the extension and retraction actions of all core-pulling structures to form the second core-pulling sequence data. The arrangement number corresponding to each group of core-pulling structures in all core-pulling structures of the mold can be the third sorting value, and the arrangement number corresponding to the mold opening operation can be the fourth sorting value. The third sorting value is a natural number, and the fourth sorting value is a positive integer. Further, when the third sorting value of a certain core-pulling structure is set to "0", it indicates that the group of core-pulling structures is not used, that is, there is no need to control the extension and retraction action of the group of core-pulling structures.

[0091] The third sorting value corresponding to different core-pulling structures can be the same or different. For example, when different core-pulling structures correspond to the same third sorting value, it can indicate that multiple core-pulling structures can perform the expansion and contraction action at the same time.

[0092] At the same time, the third sorting value is not equal to the fourth sorting value. That is, the arrangement number corresponding to each group of core pulling structure cannot be the same as the arrangement number corresponding to the mold opening operation. For example, when the fourth sorting value is "2", the third sorting value corresponding to other core pulling structures can only be set to a value other than "2".

[0093] Specifically, the core-pulling structure can be controlled differently based on the magnitude of the third and fourth sorting values. For example, if the third sorting value is less than the fourth sorting value, the core-pulling structure corresponding to the third sorting value needs to be controlled to shrink before the mold opening operation is completed. If the third sorting value is greater than the fourth sorting value, the core-pulling structure corresponding to the third sorting value needs to be controlled to shrink after the mold opening operation is completed.

[0094] Therefore, after obtaining the third sorting value of multiple core-pulling results and the fourth sorting value corresponding to the mold-opening operation through the above steps, the third and fourth target values ​​among the multiple third sorting values ​​can be determined. The third target value is the third sorting value among the multiple third sorting values ​​that is less than the fourth sorting value, and the third target value is a positive integer; the fourth target value is the third sorting value among the multiple third sorting values ​​that is greater than the fourth sorting value. Subsequently, different controls can be applied to the multiple core-pulling structures based on the third and fourth target values.

[0095] S304. Before controlling the mold to perform the mold opening operation, control the core-pulling structure in the mold corresponding to the third target value to be pulled out from the specified position inside according to the third target value in ascending order.

[0096] S305. During the mold opening operation, the core-pulling structure corresponding to the fourth target value in the mold is pulled out from the specified position inside.

[0097] In some embodiments, during the process of controlling the mold to perform a mold opening operation, controlling the core-pulling structure in the mold corresponding to the fourth target value to be pulled out from a designated internal position includes:

[0098] During the mold opening operation, it is detected whether the current position of the mold has reached the second set position.

[0099] If the current position of the mold is detected to have reached the second set position, then the core-pulling structure corresponding to the fourth target value in the mold is controlled to be pulled out from the specified position inside, in ascending order of the fourth target value.

[0100] In a specific implementation, during the process of controlling the mold to perform the mold opening operation, the real-time position of the mold can be detected by an electronic ruler to determine when to control the core-pulling structure corresponding to the fourth target value to be pulled out from the internal designated position. The second set position can be a pre-set middle plate position. The core-pulling structure will only be retracted when the mold reaches the middle plate set position.

[0101] For example, when the second set position is set to 800mm, and the sorting values ​​for mold opening operation, core pulling structure 1, and core pulling structure 2 are set to 2, 3, and 1, the control sequence of the edge trimming machine can include: before the mold is controlled to perform the mold opening operation, the core pulling structure 2 is controlled to be pulled out from the internal designated position, and then the mold is controlled to perform the mold opening operation. When the mold reaches the middle plate position of 800mm, the core pulling structure 1 is controlled to be pulled out from the internal designated position.

[0102] This embodiment provides a control method for an edge trimming machine. The second core-pulling sequence data includes: the third sorting value corresponding to each group of core-pulling structures in all core-pulling structures of the mold and the fourth sorting value corresponding to the mold opening operation. The third target value and the fourth target value among multiple third sorting values ​​are determined. This provides an accurate data basis for controlling different core-pulling structures to be pulled out from a specified position at different times. It realizes the flexible configuration of the timing of the core-pulling structure to perform the shrinkage action according to product requirements, and further meets the production needs of complex parts and the needs of future product upgrades.

[0103] Figure 4 This is a schematic diagram of the architecture of a control method for an edge trimming machine according to an embodiment of this application, referring to... Figure 4 First, the edge trimming machine can be started, and the mold can be controlled to perform the corresponding mold-locking operation. When the current position of the mold reaches the first set position, the mold can be stopped from locking, and a part of the core-pulling structure can be controlled to perform the core-pulling action, such as controlling the core-pulling structure in the mold corresponding to the first target value to insert into the designated internal position. Then, the mold can be controlled to continue to perform the mold-locking operation. When the mold is locked in place, that is, when the mold lock operation is completed, the core-pulling structure in the mold corresponding to the second target value can be controlled to insert into the designated internal position. Then, the mold locking pressure can be controlled, and the edge trimming machine can be controlled to perform the edge trimming operation. If the edge trimming machine is detected to have completed the operation, the machine can be controlled to stop the mold locking operation. In the edge trimming operation, before the mold opens, a portion of the core-pulling structure can be controlled to pull out its core. For example, the core-pulling structure corresponding to the third target value can be pulled out from a designated internal position. Then, the mold opens. During the mold opening process, it can be detected whether the current position of the mold has reached the second set position. If the current position of the mold has reached the second set position, the mold opening operation can be stopped, and the core-pulling structure corresponding to the fourth target value can be pulled out from a designated internal position. Finally, the mold can continue to open until the mold is fully opened.

[0104] Corresponding to the control method for the edge trimming machine in the above embodiment, Figure 5 This is a structural block diagram of a control device for a trimming machine provided in one embodiment of this application. For ease of explanation, only the parts related to the embodiment of this application are shown.
