Description

Technical Field

[0001] This application relates to the field of food processing technology, and in particular to a cutting device and production line. Background Technology

[0002] Shrimp meat, as the main form of consumption for white shrimp products, occupies a leading position in the shrimp processing industry. The raw material for shrimp meat production is headless frozen shrimp tails. After processes such as thawing, deveining, peeling, degumming, freezing, and packaging, the finished shrimp meat flows to downstream markets such as wholesale markets, supermarkets, e-commerce platforms, and catering companies.

[0003] Shrimp back-opening is a process in shrimp processing, and current technology still mainly relies on manual back-opening. Although there are some shrimp back-opening machines available, these machines still have problems with inconsistent depth and length when processing shallowly opened shrimp backs.

[0050] The first aspect of this application provides a cutting device, which will be described below in conjunction with... Figures 1 to 3 Describe in detail the structure and working principle of the cutting device.

[0051] According to the embodiments of this application, the cutting device includes a first conveyor belt 510, a second conveyor belt 520, a straightening wheel 410, and a cutter 110.

[0052] In this embodiment, the first conveyor belt 510 has a first conveying surface and the second conveyor belt 520 has a second conveying surface. Both the first and second conveying surfaces are inclined relative to the horizontal direction to jointly define a trough-shaped portion, which is used to convey the material to be cut.

[0053] In this embodiment, the correction wheel 410 is disposed above the groove-shaped portion. The correction wheel 410 is capable of rotating around a first axis coaxial with the correction wheel 410. The correction wheel 410 is also capable of swinging around a second axis parallel to the first axis. The correction wheel 410 is used to press against the material to be cut that passes under the correction wheel 410.

[0054] In this embodiment, the cutter 110 is located downstream of the correction wheel 410 in the conveying direction of the first conveyor belt 510, and the cutter 110 is capable of cutting the material to be cut.

[0055] Thus, according to the cutting device provided in this application embodiment, the cutting device uses the first conveyor belt 510 and the second conveyor belt 520 to define a trough-shaped portion to transport the material to be cut, ensuring that the material to be cut obtains a stable posture within the trough-shaped portion. In particular, strip-shaped materials can be confined within the trough-shaped portion with their own extension direction as the direction of transport, and to a certain extent, they will not tip over. Based on this, according to the cutting device provided in this application embodiment, when the material to be cut passes under the correction wheel 410, the material is pressed by the correction wheel 410 and moves towards the bottom side of the trough-shaped portion, so that its position can be corrected by the first conveying surface and the second conveying surface, making its own extension direction consistent with the conveying direction of the first conveyor belt 510, which facilitates the cutting of the material along its own extension direction using the cutter 110.

[0056] In this embodiment, both the first conveyor belt 510 and the second conveyor belt 520 can be conveyor belts. As an example, the structure driving each conveyor belt may include two wheel structures arranged side by side, namely a driving wheel and a driven wheel. The driving wheel can be driven by a conveyor belt motor 800. The conveyor belt is sleeved on the outside of the two wheel structures. It is understood that the axes of the two wheel structures are inclined relative to the horizontal direction, thereby ensuring that the first conveying surface and the second conveying surface can also be inclined.

[0057] Therefore, in practice, the first conveying surface and the second conveying surface can be formed as a trough with a V-shaped cross section, or a trough with a cross section approximately V-shaped, which is particularly advantageous for making the extension direction of strip-shaped materials, such as shrimp, consistent with the direction in which they are conveyed.

[0058] In this embodiment, a mounting bracket 700 may be provided, and the aforementioned wheel structure may be rotatably mounted on the mounting bracket via bearings.

[0059] According to the cutting device provided in the embodiments of this application, the cutting device may include a second transmission component and a second motor 430. The second motor 430 may be disposed on the mounting member 600, and the second transmission component may be disposed in the correction swing arm 420. The second transmission component may drive the second motor 430 and the correction wheel 410 to rotate around the first axis.

[0060] In an embodiment, as an example, the mounting member 600 can be a vertically arranged mounting plate, and the mounting plate and the correction arm 420 can be rotatably connected, for example, by opening a hole in the mounting plate and providing a bearing on the outside of the correction arm 420 to rotatably connect it to the mounting plate.

[0061] In this embodiment, the conveyor belt motor 800 mentioned above can also be mounted on the mounting member 600. Specifically, the conveyor belt motor 800 and the second motor 430 can both be fixed on the same side of the mounting plate that serves as the mounting member 600. The mounting plate can have a hole through which the motor shaft of the conveyor belt motor 800 passes, so that the conveyor belt motor 800 can be connected to the first conveyor belt 510 located on the other side of the mounting plate.

[0062] In this embodiment, the end of the motor shaft of the conveyor belt motor 800 may be provided with a wheel structure (not shown in the figure), and the drive wheel of the first conveyor belt 510 may be connected to the wheel structure for transmission, for example. For example, the drive wheel may be coaxially connected to another wheel structure (not shown in the figure), that is, the other wheel structure is the same as the drive wheel, and the axis of both is inclined relative to the horizontal plane. For example, a shaft structure (not shown in the figure) may be provided between the other wheel structure and the drive wheel. In order to hold the shaft structure, the cutting device may also provide a horizontally arranged retaining plate on the side where the first conveyor belt 510 is located, the shaft structure passing through the retaining plate and being rotatably connected to the retaining plate, for example, by sleeved with a bearing (not shown in the figure) on the outside of the shaft structure.

[0063] In one embodiment, the other wheel structure and the wheel structure at the end of the motor shaft of the conveyor belt motor 800 can be connected by a belt (not shown in the figure). That is, the belt is sleeved on the outside of the end wheel structure and the outside of the other wheel structure. In this way, when the end wheel structure is driven to rotate by the conveyor belt motor 800, it can drive the other wheel structure to rotate, and then the other wheel structure can drive the drive wheel to rotate.

[0064] It should be noted that the belts fitted onto the outer sides of the end wheel structure and the other wheel structure can be synchronous belts, and both the end wheel structure and the other wheel structure can be synchronous pulleys. It should also be noted that since the axis of the other wheel structure is inclined, the synchronous belt can be torn, as long as this torsion does not cause interference within the synchronous belt itself.

[0065] In addition, on the side where the first conveyor belt 510 of the mounting plate is located, another motor and corresponding transmission structure (not shown in the figure) can be set up with reference to the above-mentioned conveyor belt motor 800 to drive the second conveyor belt 520. Since the principle and setting method are the same, they will not be described again here.

[0066] According to the cutting device provided in the embodiments of this application, the second transmission assembly may include a third wheel component 424 and a fourth wheel component 425. In the embodiments, the third wheel component 424 may be coaxially connected to the second motor 430, the fourth wheel component 425 may be drive-connected to the third wheel component 424, and the fourth wheel component 425 may be coaxially connected to the correction wheel 410, for example, by means of a shaft.

[0067] In an embodiment, the correction arm 420 may have a second housing (that is, the second housing is rotatably connected to the mounting plate), and the third wheel member 424 and the fourth wheel member 425 are both disposed inside the second housing, wherein the third wheel member 424 and the fourth wheel member 425 are both rotatable relative to the second housing.

[0068] As an example, power can be transmitted between the third wheel component 424 and the fourth wheel component 425 via a belt. As another example, the sides of both the third wheel component 424 and the fourth wheel component 425 may each have annular grooves, allowing the belt to be positioned on the third wheel component 424 and the fourth wheel component 425 in a manner that does not protrude from the outside of the third wheel component 424 and the fourth wheel component 425. Alternatively, both the third wheel component 424 and the fourth wheel component 425 may be synchronous pulleys, and power can be transmitted between them via a synchronous belt.

[0069] Based on this, such as Figure 3 As shown, the second housing includes a first arm 422 with a first axis as its axis, a second arm 423 with a second axis as its axis, and a second housing body 421 connecting the first arm 422 and the second arm 423. The motor shaft of the second motor 430 can be coaxially connected to a shaft portion disposed within the first arm 422. A shaft member coaxial with the correction wheel 410 is disposed within the second arm 423. A bearing can be disposed between the shaft portion within the first arm 422 and the first arm 422, i.e., the bearing is sleeved on the outside of the motor shaft. Therefore, both the motor shaft and the aforementioned shaft member can rotate relative to their respective arm portions.

[0070] In this embodiment, the end of the shaft portion within the first arm 422 is fixedly connected to the third wheel member 424 as described above, and the end of the shaft member as described above is fixedly connected to the fourth wheel member 425 as described above. Furthermore, as mentioned above, the third wheel member 424 and the fourth wheel member 425 can be connected by a drive connection such as a belt or a timing belt.

[0071] It should be noted that even if the second motor 430 does not drive the correction wheel 410 to rotate, the correction wheel 410 can still correct the posture of the material by applying pressure to it. The purpose of the correction wheel 410 being driven by the second motor 430 is to match the speed of the object's movement with the rotation speed of the correction wheel 410, reduce the resistance between the material and the correction wheel 410, thereby ensuring that the material moves at the same speed as the first conveyor belt 510 and the second conveyor belt 520 without slippage, and improving the stability of the shrimp delivery.

[0072] Furthermore, as described later, the first conveyor belt 510 may also have a first needle-like portion protruding from the first conveying surface, and the second conveyor belt 520 may also have a second needle-like portion protruding from the second conveying surface. Both the first and second needle-like portions are used to pierce the object to be cut, such as a shrimp body. In the embodiment, since the cutter 110 cuts the shrimp back curve, which is essentially a two-dimensional curve defined by two dimensions: length (horizontal axis) and height (vertical axis), the height is obtained by the encoder described later, i.e., calculated by the rotation of the detection pressure roller. The length can be ensured by the needle-like portion piercing the shrimp body, ensuring that there is no slippage between the shrimp body and the conveyor belt during the shrimp body transportation process and that there is no positional deviation in the precise drive of the conveyor belt (e.g., driven by a servo motor), thus guaranteeing the accuracy of the obtained length.

[0073] Furthermore, in the embodiment, the correction wheel 410 presses down on the shrimp body, which can correct the shrimp body posture on the one hand, and on the other hand, as mentioned above, promotes the needle part to penetrate the shrimp body when pressing down, ensuring that the shrimp body does not slip on the conveyor belt, and ensuring that the detection wheel 310 detects accurately and the cutter 110 cuts accurately.

[0074] According to the cutting device provided in the embodiments of this application, the cutting device may further include a detection component. The detection component may include a detection wheel 310 and an encoder 330 arranged parallel to each other (i.e., the axes of the detection wheel 310 and the encoder 330 are parallel). The detection component is arranged in the conveying direction between the correction wheel 410 and the cutter 110. The detection wheel 310 can rotate around a third axis coaxial with the detection wheel 310, and the detection wheel 310 can also swing around a fourth axis parallel to the third axis.

[0075] In one embodiment, the detection wheel 310 can be disposed above the grooved portion. The detection wheel 310 can be used to continuously press against the material to be cut as it passes beneath the detection wheel 310, and the encoder 330 acquires the swing state of the detection wheel 310 as the material to be cut passes through it. In another embodiment, the cutting device further includes a control mechanism, which is communicatively connected to the encoder 330 to receive the swing state and control the height at which the cutter 110 cuts the material to be cut.

[0076] In this embodiment, the angle of the detector wheel 310 changes as the material passes through it. The encoder 330 acquires this change, which is received by the control mechanism. Based on this change, the subsequent cutter 110 is controlled to cut the material in the same way as the height change, such as cutting the back of a shrimp. This allows the shrimp to be cut according to its own outline, ensuring the accuracy of the cut.

[0077] In the embodiment, since the detection wheel 310 continuously presses against the material to be cut passing underneath it, this contact detection gives the detection wheel 310 pressure on the shrimp body when the material to be cut, such as shrimp, passes by, and the detection wheel 310 always fits against the shrimp, which can reduce detection interference.

[0078] In this embodiment, the detection wheel 310 also has a corresponding swing arm, namely the detection swing arm 320. The detection swing arm 320, which is coaxial with the detection wheel 310, can be equipped with a bearing to reduce the rotational resistance of the detection wheel 310 and the resistance between the material and the detection wheel 310, thereby ensuring that the material moves at the same speed as the first conveyor belt 510 and the second conveyor belt 520 without slippage, and improving the stability of shrimp delivery.

[0079] In other words, a bearing is provided inside the detection arm 320, which is sleeved on the outer side of the shaft of the detection wheel 310, to ensure that the detection wheel 310 can rotate relative to the detection arm 320. Furthermore, the detection arm 320 can be, for example, a solid arm structure, which is rotatably connected to the mounting member 600 via, for example, a bearing, and connected to an encoder 330 mounted on the mounting member 600. That is, the detection arm 320 and the encoder 330 are coaxially arranged so that the rotation of the detection arm 320 can be obtained through the encoder 330.

[0080] In the embodiment, the continuous pressing of the material by the detection wheel 310 mentioned above can be achieved by the weight of the detection wheel 310 and the detection swing arm 320. That is, when the material is conveyed by the two conveyor belts, the material, such as shrimp, will use its back to overcome the weight of the detection wheel 310 and the detection swing arm 320 when it passes the position of the detection wheel 310, and lift the detection wheel 310 up. Because of its own weight, the detection wheel 310 always has a downward tendency after being lifted up, so it can achieve continuous pressing of the material.

[0081] According to the cutting device provided in the embodiments of this application, the cutter may have a fifth axis, the cutter may rotate around the fifth axis to cut the material to be cut, and the cutter may also swing around a sixth axis parallel to the fifth axis.

[0082] In an embodiment, the cutting device may further include a mounting member 600 and a cutting swing arm 120. The cutter 110 may be rotatably connected to the cutting swing arm 120 so as to be able to rotate about a fifth axis. The cutting swing arm 120 may be rotatably connected to the mounting member 600 so as to drive the cutter 110 so that the cutter 110 swings about a sixth axis.

[0083] According to the cutting device provided in the embodiments of this application, the cutting device may include a first transmission component and a first motor 130. The first motor 130 may be disposed on the mounting component 600, and the first transmission component may be disposed in the cutting swing arm 120. The first transmission component may drive the first motor 130 and the cutter 110 to rotate around the fifth axis.

[0084] A third transmission assembly can be installed on the outer side of the cutting arm 120. The third transmission assembly can include a drive wheel, a driven wheel, and a conveyor belt. The conveyor belt is connected to a third motor 140 with a drive wheel. For example, the outer side of the cutting arm 120 can have a driven wheel. The drive wheel and the driven wheel are connected by the conveyor belt, so that the cutting arm 120 rotates relative to the mounting member 600. The rotation can still be achieved by bearings, so that the cutting arm 120 is driven to rotate by the third motor 140, which in turn drives the cutter 110, so that the cutter 110 swings around the sixth axis.

[0085] Similar to the second transmission assembly described above, the first transmission assembly may include a first wheel component and a second wheel component. The first wheel component may be coaxially connected to the first motor 130, and the second wheel component may be drivenly connected to the first wheel component. The second wheel component is coaxially connected to the cutter 110.

[0086] In an embodiment, the cutting arm 120 may have a first housing, and both the first wheel component and the second wheel component may be disposed inside the first housing, wherein both the first wheel component and the second wheel component are rotatable relative to the first housing.

[0087] As mentioned above, the form of the first transmission component can be exactly the same as that of the second transmission component, including the transmission method between the first wheel component and the second wheel component. The transmission method between the first wheel component and the second wheel component can also be belt drive. In addition, they can also be connected to the two arms of the first housing by bearings between themselves and the inner walls of their respective arms. The configuration of the first motor 130 can be the same as that of the second motor 430, so it will not be described again here.

[0088] According to the cutting apparatus provided in the embodiments of this application, the cutting apparatus may further include a cutting pressure roller 210. The cutting pressure roller 210 may be disposed upstream of the cutter in the conveying direction. The cutting pressure roller 210 is capable of rotating about a seventh axis coaxial with the cutting pressure roller 210, and the cutting pressure roller 210 is also capable of swinging about an eighth axis parallel to the seventh axis. The cutting pressure roller 210 also achieves swinging by providing a pressure roller swing arm 220 rotatably connected to the mounting plate, similar to that described above.

[0089] In one embodiment, the cutting roller 210 may be disposed above the grooved portion for pressing down on the material to be cut as it passes below the cutting roller 210. Further, the cutting roller 210 may have an annular groove disposed on its side, the annular groove being used to press down on the material to be cut, and the cutter 110 extending into the annular groove.

[0090] In this embodiment, the cutting pressure roller 210 is basically the same as the calibration pressure roller in terms of its arrangement. The difference is that the cutting pressure roller 210 is located adjacent to the cutter 110 and upstream of the cutter 110. This "adjacent" arrangement means that the cutter 110 extends into the annular groove of the cutting pressure roller 210. The function of the cutting pressure roller 210 is to use the annular groove to position and shape the material, ensuring accurate and stable cutting by the cutter 110. Since the cutter 110 extends into the annular groove, it is easy to understand that when the cutting pressure roller 210 presses down on the material, the material is immediately cut by the cutter 110, making the interaction between the cutter 110 and the cutting pressure roller 210 instantaneous.

[0091] According to the cutting device provided in the embodiments of this application, as a specific example, the cutting device may further include a correction arm 420, a correction wheel 410 which is rotatably connected to the correction arm 420 so as to be able to rotate around a first axis, and the correction arm 420 is rotatably connected to the mounting member 600 so as to make the correction wheel 410 swing around a second axis.

[0092] According to the cutting device provided in the embodiments of this application, the first conveyor belt 510 may have a first needle-like part (e.g., a needle structure 530) protruding from the first conveying surface. The first needle-like part is used to pierce into the material to be cut. The second conveyor belt 520 has a second needle-like part (e.g., a needle structure 530) protruding from the second conveying surface. The second needle-like part is used to pierce into the material to be cut, thereby facilitating the positioning of the material to be cut. As an example, as described above, the material to be cut may be a shrimp. Both the first needle-like part and the second needle-like part pierce the shrimp shell, and the cutter performs a back-opening cut on the shrimp.

[0093] In addition, as an example, the angle between the first conveying surface and the second conveying surface is 45° to 90°. Too small an angle may cause the material to be cut to be over-clamped, while too large an angle will make it difficult to straighten the material. This angle range is convenient for shrimp of different sizes to be well centered and for the spikes to penetrate well.

[0094] In addition, the sides of the correction wheel 410 and the detection wheel 310 can have annular grooves, for example, they can be the same as the annular grooves of the cutting pressure wheel 210, both being V-shaped cross-section grooves. The sides of the correction wheel 410 and the detection wheel 310 can also be outer cylindrical surfaces.

[0095] According to a second aspect of the embodiments of this application, a production line is provided. The production line includes the cutting device as described above and also has the above-mentioned beneficial effects, which will not be repeated here. The production line can be, for example, a shrimp peeling production line, that is, the cutting device as described above performs the back-opening operation on the shrimp as a preparatory step for peeling the shrimp.

[0096] The above are merely preferred embodiments of this application and do not limit the scope of protection of this application. All equivalent structural transformations made based on the innovative concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
