Description

Technical Field

[0001] This utility model relates to the field of unpacking technology, and in particular to a tape-cutting device and unpacking equipment. Background Technology

[0002] In product tape cutting and unpacking operations, the tape cutting device, as the core equipment of the unpacking equipment, plays a key role in quickly and accurately removing the packaging tape.

[0003] In existing tape-cutting devices, during frequent operation, the packaging tape compresses the stop block within the device, causing the stop block to slide along the connected support shaft within the device's support. Because the stop block is subjected to impacts from the packaging tape from various directions and operates under high load for extended periods, the support suffers severe wear, leading to axial movement of the support shaft. This shortens the lifespan of the tape-cutting device, reduces the stability of the cutting process, and can also cause the stop block to shift position, creating gaps between it and the clamping mechanism. This allows the packaging tape to easily get stuck in these gaps, causing the tape-cutting device to jam, requiring manual intervention and significantly reducing tape-cutting and unpacking efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a tape cutting device and unpacking equipment to extend the service life of the tape cutting device, reduce the wear of the support in the tape cutting device, improve the stability of the tape cutting and unpacking process, and at the same time avoid the tape cutting device from jamming, thereby improving the tape cutting and unpacking efficiency.

[0005] To achieve this objective, the technical solution adopted by this utility model is as follows:

[0006] A tape-cutting device includes a clamping mechanism and a stop mechanism. The stop mechanism includes a support and a telescopic assembly, with the support positioned below the clamping mechanism. The telescopic assembly includes:

[0007] A support shaft, one end of which is axially movable through the support;

[0008] A stop block, the top of which is parallel to and abuts against the bottom of the clamping mechanism, and the other end of the support shaft located outside the support is connected to the stop block so that the stop block has an initial position and a clamping position; the clamping mechanism is configured to clamp the packaging tape to be cut when the stop block moves to the clamping position;

[0009] An auxiliary shaft is provided, which is parallel to the support shaft. One end of the auxiliary shaft is axially movably inserted through the support, and the other end of the auxiliary shaft located outside the support is connected to the stop block.

[0010] A reset element, configured to ensure that the stop always tends to move to the initial position.

[0011] As an optional solution, the tape cutting device further includes a switch configured to control the clamping mechanism to clamp the packaging tape when triggered;

[0012] The telescopic assembly also includes a guide block, and the guide block is connected to one end of the support shaft located inside the support. When the stop block moves to the clamping position, the guide block triggers the switch.

[0013] As an optional solution, the support has a groove and a through hole for the support shaft to pass through. The groove extends along the length direction of the support, and the guide block is slidably disposed in the groove. One end of the through hole communicates with the groove, and the other end of the through hole penetrates one side of the support along the length direction. The length direction of the support is parallel to the axial direction of the support shaft.

[0014] As an optional solution, the support may be symmetrically provided with two telescopic components on both sides along the length direction.

[0015] As an option, the support shaft is provided with at least two auxiliary shafts spaced apart circumferentially.

[0016] As an optional solution, the support has at least two guide holes, one end of the auxiliary shaft is axially movably inserted into the corresponding guide hole, and the other end of the auxiliary shaft is threadedly connected to the corresponding stop block.

[0018] As an optional solution, the spring is sleeved on the support shaft and / or the auxiliary shaft.

[0019] Alternatively, the support may be a copper base.

[0020] Unpacking equipment, including the aforementioned tape-cutting device.

[0021] The beneficial effects of this utility model are as follows:

[0022] The tape-cutting device proposed in this utility model adds an auxiliary shaft between the support and the stop block, so that the auxiliary shaft and the support shaft jointly support the stop block. The pressure of the packaging tape on the stop block is distributed on the support shaft and the auxiliary shaft, which disperses the force on the support shaft, reduces the wear of the support, and extends the service life of the tape-cutting device. At the same time, it can also prevent the axial movement of the support shaft from causing the stop block to shift position, improve the stability of the tape-cutting and unpacking process, and prevent gaps from appearing between the stop block and the clamping mechanism, thus preventing the packaging tape from getting stuck in the gaps. This improves the reliability of the tape-cutting and unpacking process, reduces the amount of manual secondary processing, and improves the efficiency of tape-cutting and unpacking.

[0023] The unpacking equipment proposed in this utility model includes the aforementioned tape-cutting device, which extends the service life of the tape-cutting device, improves the stability and reliability of the tape-cutting and unpacking process, reduces the workload of manual secondary processing, and improves the efficiency of tape-cutting and unpacking.

[0028] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] This embodiment proposes an unpacking device, which includes a tape cutting device and a feeding device. The tape cutting device is used to cut the packaging tape tied to the outer packaging of the product, and the feeding device is used to separate the cut packaging tape from the product, so as to realize the automatic tape cutting and unpacking process.

[0034] This embodiment also proposes a tape-cutting device, which includes a clamping mechanism, a stop mechanism, and a cutting mechanism. The robotic arm of the unpacking device drives the clamping mechanism to move towards the product and causes the packaging tape to fall into the jaws of the clamping mechanism. During this process, the packaging tape can compress the stop mechanism. When the stop mechanism is compressed into place, the clamping mechanism clamps the packaging tape, and the cutting mechanism then cuts the packaging tape. Finally, the cut packaging tape is removed from the product by the unloading device.

[0035] Specifically, the clamping mechanism includes a fixed clamp and a movable clamp. The robotic arm drives the fixed clamp to approach the product, then moves it tightly against the outer surface of the product towards the packaging tape to be cut. The packaging tape wrapped around the product falls between the fixed clamp and the movable clamp. As the clamping mechanism continues to move, the packaging tape presses against the stop mechanism. When the stop mechanism is in place, the movable clamp moves towards the fixed clamp until the fixed clamp and the movable clamp together clamp the packaging tape. Subsequently, the shearing mechanism's scissors cut the packaging tape, and the unloading device moves to the position of the cut packaging tape and grabs it (at this time, the clamping mechanism has released the packaging tape). The unloading device then clamps the cut packaging tape away from the product. The specific structure and working process of the clamping mechanism, shearing mechanism, and unloading device will not be described in detail here.

[0036] like Figure 1 and Figure 2As shown, the stop mechanism includes a support 1 and a telescopic assembly, with the support 1 positioned below the clamping mechanism. The telescopic assembly includes a support shaft 2, a stop 3, and a reset member 5. One end of the support shaft 2 is axially (left-right direction in the figure) and movably passes through the support 1. The top end of the stop 3 is parallel to and abuts against the bottom end of the clamping mechanism, and the other end of the support shaft 2, located outside the support 1, is connected to the stop 3, giving the stop 3 an initial position and a clamping position. The clamping mechanism is configured to clamp the packaging tape to be cut when the stop 3 moves to the clamping position. The reset member 5 is configured to ensure that the stop 3 always tends to move back to the initial position.

[0037] Before the packaging tape enters the fixed clamp and the movable clamp, the stop block 3 is not subjected to external force and is in its initial position. As the packaging tape enters between the fixed and movable clamps, and the tape-cutting device continues to move, the packaging tape moves towards the interior of the fixed and movable clamps and presses against the stop block 3. After being pressed, the stop block 3 moves from its initial position towards the support 1. The support shaft 2, connected to the pressed stop block 3, slides synchronously in the left-right direction relative to the support 1. When the stop block 3 moves to the clamping position, the fixed clamp and the movable clamp together clamp the packaging tape. This completes the tape cutting and subsequent separation of the packaging tape from the product. Finally, under the action of the reset component 5, the stop block 3 moves from the clamping position back to its initial position to prepare for the tape cutting operation on the next packaging tape.

[0038] When the tape cutting device operates frequently, the packaging tape compresses the stop block 3, causing the stop block 3 to drive the connected support shaft 2 to slide within the support 1 of the tape cutting device. Because the stop block 3 is subjected to impacts from different directions by the packaging tape and operates under high load for extended periods, the support 1 experiences severe wear, leading to axial movement of the support shaft 2. This shortens the service life of the tape cutting device, reduces the stability of the tape cutting process, and causes the stop block 3 to shift position, creating a gap between it and the clamping mechanism of the tape cutting device. This makes it easy for the packaging tape to get stuck in the gap, causing the tape cutting device to jam and requiring manual secondary processing, significantly reducing the tape cutting and unpacking efficiency.

[0039] To solve the above problems, such as Figure 1 and Figure 2As shown, the telescopic assembly also includes an auxiliary shaft 4, which is arranged parallel to the support shaft 2. One end of the auxiliary shaft 4 is axially movably inserted through the support 1, and the other end of the auxiliary shaft 4, located outside the support 1, is connected to a stop block 3. By adding the auxiliary shaft 4 between the support 1 and the stop block 3, the auxiliary shaft 4 and the support shaft 2 jointly support the stop block 3. The pressure of the packaging tape on the stop block 3 is distributed on the support shaft 2 and the auxiliary shaft 4, dispersing the force on the support shaft 2, reducing the wear of the support 1, and extending the service life of the tape cutting device. At the same time, it can also prevent the support shaft 2 from axially shifting, which would cause the stop block 3 to shift position, thus improving the stability of the tape cutting and unpacking process. This ensures that there are no gaps between the stop block 3 and the clamping mechanism, preventing the packaging tape from getting stuck in the gaps, improving the reliability of the tape cutting and unpacking process, reducing the workload of manual secondary processing, and improving the efficiency of tape cutting and unpacking.

[0040] It should be noted that the tape-cutting device also includes a switch, which is configured to control the clamping mechanism to clamp the packaging tape when triggered. The telescopic assembly also includes a guide block 6, with one end of the support shaft 2 located within the support 1 connected to the guide block 6. When the stop block 3 moves to the clamping position, the guide block 6 triggers the switch. The aforementioned switch is a proximity switch, which has the advantages of high reliability and stability, short response time, and a compact structure, facilitating flexible installation. When the stop block 3 moves from the initial position to the clamping position, the guide block 6 connected to the support shaft 2 triggers the proximity switch. The proximity switch is electrically connected to the control module of the tape-cutting device to transmit the trigger signal to the control module. The control module controls the fixed clamp and movable clamp of the clamping mechanism to move closer to each other to clamp the packaging tape. Since the control module is existing technology, its operation will not be described in detail.

[0041] In an optional embodiment, the support 1 has a groove 11 and a through hole 12 for the support shaft 2 to pass through. The groove 11 extends along the length of the support 1, and the guide block 6 is slidably disposed within the groove 11. One end of the through hole 12 communicates with the groove 11, and the other end of the through hole 12 penetrates one side of the support 1 along its length. The length direction of the support 1 (left-right direction in the figure) is parallel to the axial direction of the support shaft 2. The sliding engagement between the through hole 12 and the support shaft 2 improves the stability of the support shaft 2 sliding in the left-right direction within the through hole 12. The sliding engagement between the guide block 6 and the groove 11 allows the guide block 6 to move in the left-right direction within the groove 11 when the stop block 3 moves between the initial position and the clamping position, providing good guidance and limiting for the movement of the stop block 3 and improving the stability of the stop block 3 during its movement between the initial position and the clamping position.

[0042] It should be noted that the tape cutting device includes two clamping mechanisms symmetrically arranged in the left-right direction. This allows the tape cutting device to flexibly select one of the clamping mechanisms to clamp and cut the packaging tape according to its different positions, improving the flexibility and efficiency of the tape cutting and unpacking. Correspondingly, two telescopic components are symmetrically arranged on both sides of the support 1 along its length. The two telescopic components are respectively located below the left and right clamping mechanisms, so that when the packaging tape enters between the fixed and movable clamps of different clamping mechanisms, it can press against the corresponding stop 3, thereby triggering the switching element.

[0043] like Figure 1 and Figure 2 As shown, at least two auxiliary shafts 4 are arranged at circumferential intervals along the support shaft 2. By providing at least two auxiliary shafts 4, the number of auxiliary shafts 4 is increased, improving the support effect on the stop block 3. This disperses the pressure exerted by the packaging tape on the stop block 3 to the support shaft 2 and the at least two auxiliary shafts 4, further reducing the force on the support shaft 2. This reduces the wear of the through hole 12 inside the support 1, increases the service life of the tape cutting device, and further improves the stability of the tape cutting and unpacking process.

[0044] In an optional embodiment, the support 1 has at least two guide holes 13. One end of the auxiliary shaft 4 is axially movably inserted through the corresponding guide hole 13, and the other end of the auxiliary shaft 4 is threadedly connected to the corresponding stop 3. By providing guide holes 13, the auxiliary shaft 4 can slide within the guide holes 13, thereby limiting and guiding the auxiliary shaft 4. This improves the stability of the auxiliary shaft 4 as it moves with the support shaft 2 in the left and right directions, and prevents the support shaft 2 from axially shifting, which could cause the stop 3 to shift position. This improves the stability of the tape cutting and unpacking process.

[0045] In this embodiment, the stop block 3 is a rectangular plate, and two auxiliary shafts 4 are provided. The two auxiliary shafts 4 are distributed along one diagonal of the stop block 3, and one end of the two auxiliary shafts 4 is threaded to the two corners of the stop block 3 on the same diagonal. This improves the stability of the connection between the auxiliary shafts 4 and the stop block 3, and also enables quick assembly and disassembly of the auxiliary shafts 4 and the stop block 3, facilitating the disassembly, assembly, and replacement of the auxiliary shafts 4. In other embodiments, three or more auxiliary shafts 4 may be provided, which is not specifically limited here.

[0046] In an optional embodiment, the reset element 5 is a spring, and the spring is sandwiched between the stop block 3 and the support 1. The spring structure is simple and easy to assemble and disassemble. When the packaging tape presses against the stop block 3, and the stop block 3 moves from the initial position toward the support 1 after being compressed, the spring is compressed; when the stop block 3 moves to the clamping position, the packaging tape is cut. Finally, under the action of the elastic restoring force of the spring, the stop block 3 moves from the clamping position to the initial position so as to cut the next packaging tape.

[0047] In this embodiment, a spring is sleeved on the support shaft 2 to provide support for the installation of the spring and prevent the spring from bending or shifting position during compression and reset. In other embodiments, a spring is sleeved on the auxiliary shaft 4, or both the support shaft 2 and the auxiliary shaft 4 are sleeved with springs. It is only necessary to ensure that the spring can provide sufficient elastic restoring force to the stop block 3. There are no specific limitations on the number and installation position of the springs.

[0048] In one optional embodiment, the support 1 is a copper base. The support 1 is made of copper, which has good machinability and facilitates its manufacturing. Through the self-lubricating principle of copper, a self-lubricating film (composed of copper surface oxides and other impurities) can form on the inner wall of the through hole 12 of the support 1, thus forming a protective layer that reduces the friction between the support 1 and the support shaft 2, thereby reducing the wear of the through hole 12 of the support 1. In other embodiments, the support 1 may also be made of other materials.

[0049] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
