[0004] In order to achieve the above object, the present invention provides a shrimp head and tail orientation device, comprising:

[0005] At least two groups of first conveyor belt mechanisms, with a first gap defined between two adjacent groups of first conveyor belt mechanisms for the shrimp bodies to pass through and to hold the shrimp heads;

[0006] at least one set of second conveyor belt mechanisms, one end of the second conveyor belt mechanism being disposed in the first gap and the other end thereof extending out of the first gap along a discharging direction; and

[0007] The unloading mechanism is arranged at the discharge end of the second conveyor belt mechanism.

[0008] A further improvement of the technical solution is that the width H of the first gap is 5 mm to 15 mm.

[0011] A further improvement of the present technical solution is that the inner wall of the positioning groove is in an arc-shaped structure, the cross-section of the first conveyor belt is circular, and the outer peripheral surface of the first conveyor belt is in contact with the inner wall of the positioning groove.

[0012] A further improvement of the present technical solution is that the distance L between the axis of the first active roller and the axis of the first passive roller is not less than 100 mm.

[0013] A further improvement of the technical solution is that it further includes a first driving shaft and a first passive shaft, and at least two groups of first driving rollers and first passive rollers of the first conveyor belt mechanism are respectively sleeved on the first driving shaft and the first passive shaft.

[0017] The implementation of the embodiments of the present invention has the following technical effects:

[0018] When the shrimp body falls onto the first conveyor belt mechanism, the shrimp body falls into the first gap, and the shrimp head is stuck above the first gap, so that the shrimp body presents a shape with the head and tail extending up and down and is conveyed forward along the conveying direction of the first conveyor belt mechanism. When the tail of the shrimp body contacts the second conveyor device, due to the difference in conveying speed between the first conveyor belt mechanism and the second conveyor belt mechanism, after a period of time, the shrimp body is arranged with the head in front or the tail in front along the conveying direction of the first conveyor belt mechanism. Therefore, when the shrimp body is discharged from the first conveyor belt mechanism, the head or tail is kept in the front position, thereby realizing the head-tail orientation of the shrimp body along the feeding direction;

[0019] Specifically, when the conveying speed of the first conveyor belt mechanism is greater than the conveying speed of the second conveyor belt mechanism, the shrimp bodies are discharged with their heads in front and their tails in the back; when the conveying speed of the first conveyor belt mechanism is less than the conveying speed of the second conveyor belt mechanism, the shrimp bodies are discharged with their heads in the back and their tails in the front, thereby achieving flexible control of the shrimp bodies to be discharged in different head and tail directions to cooperate with the corresponding shrimp body processing procedures. There is no need for manual placement, which reduces labor input, reduces misoperation, and improves product processing qualification rate and production efficiency.

[0036] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0037] In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" and the like to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0038] Furthermore, the present invention uses terms such as "first" and "second" to describe various types of information, but such information should not be limited to these terms. These terms are merely used to distinguish information of the same type from one another. For example, "first" information could also be referred to as "second" information, and similarly, "second" information could also be referred to as "first" information without departing from the scope of the present invention.

[0039] refer to Figure 1 - Figure 6 One embodiment of the present invention provides a shrimp head and tail orienting device, comprising a first conveyor belt mechanism 100 , a second conveyor belt mechanism 200 and a feeding mechanism 300 .

[0040] There are at least two groups of first conveyor belt mechanisms 100, and a first gap 400 is defined between two adjacent groups of first conveyor belt mechanisms 100 for the shrimp bodies to pass through and clamp the shrimp heads.

[0041] The number of the second conveyor belt mechanism 200 is at least one group, one end of the second conveyor belt mechanism 200 is disposed in the first gap 400, and the other end extends out of the first gap 400 along the discharge direction; and

[0042] A discharge mechanism 300 is provided at the discharge end of the second conveyor belt mechanism 200;

[0043] The conveying speed of the first conveyor belt mechanism 100 is different from the conveying speed of the second conveyor belt.

[0044] In this way, when the shrimp body falls onto the first conveyor belt mechanism 100, the shrimp body falls into the first gap 400, and the shrimp head is stuck above the first gap 400, so that the shrimp body presents a shape with the head and tail extending up and down and is conveyed forward along the conveying direction of the first conveyor belt mechanism 100. When the tail of the shrimp body contacts the second conveying device, due to the difference in conveying speed between the first conveyor belt mechanism 100 and the second conveyor belt mechanism 200, after a period of time, the shrimp body is arranged with the head in front or the tail in front along the conveying direction of the first conveyor belt mechanism 100. Therefore, when the shrimp body is discharged from the first conveyor belt mechanism 100, the head or tail is kept in the front position, thereby realizing the head-tail orientation of the shrimp body along the feeding direction.

[0045] Specifically, when the conveying speed of the first conveyor belt mechanism 100 is greater than the conveying speed of the second conveyor belt mechanism 200, the shrimp bodies are discharged with their heads in front and their tails in the back. When the conveying speed of the first conveyor belt mechanism 100 is less than the conveying speed of the second conveyor belt mechanism 200, the shrimp bodies are discharged with their heads in the back and their tails in the front, thereby realizing flexible control of the shrimp bodies to be discharged in different head and tail directions to cooperate with the corresponding shrimp body processing procedures. There is no need for manual placement, which reduces labor input, reduces misoperation, and improves product processing qualification rate and production efficiency.

[0046] refer to Figure 3 Further preferably, the width H of the first gap 400 in this embodiment is 5 mm to 15 mm, so that it is suitable for processing shrimp bodies of most sizes. It should be noted that for those skilled in the art, based on the knowledge of the technical solution of this application, setting the size of the first gap 400 different from that disclosed in this application for different shrimp body sizes should also be considered within the scope of protection of the present invention.

[0047] refer to Figure 1 - Figure 2 、 Figure 4 - Figure 5 In this embodiment, to enable the first conveyor belt mechanism 100 to convey shrimp bodies while providing a first gap 400, the first conveyor belt mechanism 100 includes a first drive unit (not shown), a first conveyor belt 110, a first active roller 120, and a first passive roller 130. The first conveyor belt 110 is wound around the first active roller 120 and the first passive roller 130 to ensure synchronous rotation of the first active roller 120 and the first passive roller 130. The first drive unit is in transmission connection with the first active roller 120. Thus, the first drive unit drives the first active roller 120 to rotate, which in turn drives the first conveyor belt 110 to rotate, thereby driving the first passive roller 130 to rotate, thereby achieving a circular rotation of the first conveyor belt 110. The tails of the shrimp bodies that fall on two adjacent sets of the first conveyor belt mechanisms 100 fall into the first gap 400, and the heads of the shrimp bodies are exposed above the first gap 400. The first conveyor belts 110 of the two adjacent sets of the first conveyor belt mechanisms 100 drive the shrimp bodies toward the discharge end.

[0048] The shrimp head and tail orienting device in this embodiment further includes a first driving shaft 500 and a first passive shaft 600. At least two groups of first driving rollers 120 and first passive rollers 130 of the first conveyor belt mechanisms 100 are respectively mounted on the first driving shaft 500 and the first passive shaft 600. The first driving rollers 120 of the at least two groups of first conveyor belt mechanisms 100 are rotated at the same speed via the first driving shaft 500, thereby ensuring that the first conveyor belts 110 of adjacent first conveyor belt mechanisms 100 move synchronously to clamp and convey the shrimp heads.

[0049] Furthermore, the first active roller 120 and the first passive roller 130 of at least two groups of the first conveyor belt mechanism 100 are respectively slidably mounted on the first active shaft 500 and the first passive shaft 600, so as to facilitate the adjustment of the spacing between the two groups of first conveyor belts, thereby adapting to the directional conveying of shrimp bodies of different sizes. Specifically, a spacer ring 800 is provided between the two adjacent groups of first conveyor belt mechanisms 100, and the first active shaft 500 and the second passive shaft are both sleeved with a plurality of spacer rings 800. The two axial side surfaces of the spacer ring 800 are respectively fitted with the two adjacent groups of first conveyor belt mechanisms 100. It should be noted that the spacer ring 800 is provided between the two adjacent groups of first conveyor belt mechanisms 100. 00 between the first active roller 120 and the first active roller 120, the first passive roller 130 and the first passive roller 130, and the two sides of the spacer ring 800 axially fit the first active roller 120 and the first passive roller 130, so that by using spacer rings 800 of different axial sizes, the interval between the two adjacent groups of first conveyor belt mechanisms 100 is fixed, thereby ensuring the stability of the width of the first gap 400 during the operation of the device, thereby ensuring the stability of the width of the first gap 400 during the operation of the device; it should be noted that the spacer ring 800 can be detachably assembled with the first active roller 120 and the first passive roller 130 or integrally formed.

[0050] In order to achieve reliable transmission of the second conveyor belt mechanism 200, the shrimp head and tail orienting device in this embodiment also includes a second driving shaft 700 arranged parallel to the first driving shaft 500. The second conveyor belt mechanism 200 includes a second driving unit (not shown in the figure), a second conveyor belt 210 and a second passive roller (not shown in the figure). The second passive roller is sleeved on the first driving shaft 500 and can rotate relative to the first driving shaft 500. The second conveyor belt 210 is wound around the second passive roller and the second driving shaft 700 so that the second driving shaft 700 and the second passive roller rotate synchronously. The second driving shaft 700 is driven by the second driving unit to rotate and drive the second conveyor belt 210 to rotate, and the linear speed of the rotation is different from the linear speed of the first conveyor belt 110, thereby achieving head and tail directional discharge of the shrimp bodies.

[0051] It should be noted that, since the tail ends of shrimp bodies of different lengths enter the first gap 400 to different depths after the shrimp bodies fall into the first gap 400, in order to adapt to shrimp bodies of different lengths and ensure that the tail ends of the shrimp bodies are in contact with the second conveyor belt 210 when the shrimp bodies move above the second conveyor belt 210, thereby pulling the tail ends of the shrimp bodies to lag behind or lead the heads of the shrimp bodies, thereby achieving head-tail directional discharge of the shrimp bodies, the position of the second conveyor belt 210 in the first gap 400 can be adjusted by setting second passive rollers of different diameters to adapt to shrimp bodies of different lengths, and the second conveyor belt 210 can be in contact with the tails of the shrimp bodies, so that a transmission speed difference is generated between the heads and tails of the shrimp bodies, thereby achieving head-tail directional discharge.

[0052] Furthermore, in this embodiment, one end of the second conveyor belt 210 is arranged in the first gap 400, and the other end extends out of the first gap 400, so that when the shrimp bodies come out of the first gap 400, they fall onto the second conveyor belt 210 for transportation, ensuring that the shrimp bodies are discharged neatly from the first gap 400.

[0053] In order to prevent the shrimp bodies from falling off the second conveyor belt 210 when being discharged from the first gap 400, guide blocks 900 are respectively provided on both sides of the second conveyor belt in this embodiment, thereby further improving the reliability of shrimp feeding.

[0054] Further preferably, reference Figure 6 In this embodiment, the outer circumference of the first active roller 120 and the outer circumference of the first passive roller 130 are both provided with positioning grooves 140, and the first conveyor belt 110 is embedded in the positioning grooves 140, so that the first conveyor belt 110 can stably rotate at the limited positions of the first active roller 120 and the first passive roller 130.

[0055] Among them, the inner wall of the positioning groove 140 is an arc-shaped structure, the cross-section of the first conveyor belt 110 is circular, and the outer peripheral surface of the first conveyor belt 110 is in contact with the inner wall of the positioning groove 140, thereby increasing the friction between the first conveyor belt 110 and the first active roller 120 and the first passive roller 130, so that the first conveyor belt 110 can rotate stably and reliably.

[0056] Specifically, in this embodiment, the distance L between the axis of the first active roller 120 and the axis of the first passive roller 130 is not less than 100 mm, so that the tail of the shrimp body falling on the first conveyor belt mechanism 100 can fall into the first gap 400 as much as possible during the conveying process, thereby improving the reliability of the shrimp body positioning.

[0057] In summary, the present invention provides a first conveyor belt mechanism 100 and a second conveyor belt mechanism 200, so that a speed difference is generated between the head and tail of the shrimp body during the transmission process, thereby achieving directional output of the shrimp body with the head and tail, eliminating the need for manual alignment of the shrimp body, and improving the efficiency and reliability of the shrimp body entering the next processing step.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
