Description

Technical Field

[0001] The invention relates to the technical field of food processing equipment, in particular to a shrimp peeling equipment. Background Art

[0002] With the rapid development of transportation, coastal seafood has entered various inland areas. For shrimps, their breeding and transportation requirements are high, and the transportation cost of live shrimps is high, so preliminary processing is required to produce peeled shrimps. Now shrimp processing companies have been mainly focusing on rough processing of frozen shrimps and frozen shrimp products.

[0003] At present, there are two main methods for shelling prawns: manual shelling and machine shelling. Manual shelling has the disadvantages of slow shelling, low efficiency and the hands of production workers being easily cut by blades when opening the back and removing the inner thread. Manual shelling is a very traditional production method. There are two main ways to peel the shell by machine. One is to peel the shell by the principle of rotating friction of rollers. The headless shrimp is placed between two pairs of rollers without precise positioning. The rollers rotate and rub the shrimp shells repeatedly to loosen the shrimp shells and are taken away by the rotating clamps of the rollers, leaving the shrimp meat. The disadvantages are that the raw materials need to be soaked and pre-treated for a long time, the shelling is not clean, and the yield is low. The other is a semi-automatic shelling machine, which manually places the headless shrimps one by one in the conveyor belt tray slot and then feeds them into the machine. The conveyor device is used to make the headless shrimps pass through various functional stations such as positioning clamping, back opening, shelling, and deveining one by one to achieve the shelling of the headless shrimps. Although the semi-automatic shelling machine can achieve shelling, it is inefficient and can only cut the shrimp body to peel the shell. The integrity of the peeled shrimp is poor, and there are many broken shrimp skins remaining on the shrimp meat. These shortcomings have led to a small application range of existing shrimp peeling machinery and equipment, and it cannot be promoted on a large scale. Summary of the invention

[0040] In the description of the present invention, it should be understood that the terms "connected", "connected", "fixed" and the like used in the present invention should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or a welding connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] like Figure 1 and Figure 2 As shown, a preferred embodiment of the present invention provides a shrimp peeling device, comprising: a frame 100, a driving member 200, a first conveying wheel 300, a second conveying wheel 400, a conveyor belt 500, a clamping frame 600, a cutting assembly 700 and a shelling frame 800, wherein the driving member 200 is used to provide a driving force and is installed on the frame 100; the first conveying wheel 300 is connected to the output end 210 of the driving member 200 and is installed on the frame 100; the second conveying wheel 400 is installed The conveyor belt 500 is installed on the frame 100; the conveyor belt 500 is connected to the first conveyor wheel 300 and the second conveyor wheel 400 by transmission; the clamping frame 600 is provided with a first channel 610 for the conveyor belt 500 to pass from back to front, and the top of the clamping frame 600 is provided with a processing opening 620 connected with the first channel 610. When the conveyor belt 500 passes through the first channel 610, the two sides of the conveyor belt 500 are bent upwards relative to each other to clamp the shrimp body in a vertical state for transportation; The cutting assembly 700 is disposed at the processing opening 620 and can extend into the first channel 610 to open the back or belly of the shrimp clamped on the conveyor belt 500; the shelling rack 800 is located at the front side of the clamping rack 600, and the shelling rack 800 is provided with a second channel 810 for the conveyor belt 500 to pass through from back to front, and the second channel 810 includes a limiting cavity 811 and a narrowing cavity 812 which are connected in sequence from back to front, and the width of the narrowing cavity 812 is smaller than that of the limiting cavity 811. 1, a discharge port 820 is provided at the top of the shelling rack 800, and the discharge port 820 is located at the connection position between the limiting cavity 811 and the narrowing cavity 812 and communicates with the limiting cavity 811. When the conveyor belt 500 passes through the connection position between the limiting cavity 811 and the narrowing cavity 812, the narrowing cavity 812 tightens the conveyor belt 500 to squeeze the shrimp body to separate the shrimp meat output through the discharge port 820 and the shrimp shell carried away by the conveyor belt 500.

[0042] In the shrimp peeling equipment based on the above technical features, the clamping frame 600 uses the first channel 610 inside it to make the conveyor belt 500 bend upward and fold in half to clamp and convey the shrimp body, and the shrimp body can be kept in a vertical state. When the shrimp body to be processed passes through the processing port 620, the cutting assembly 700 rotates to cut the back of the shrimp body or the abdomen. The shrimp body after cutting is conveyed to the shelling frame 800. When the shrimp body passes through the limiting cavity 811 and reaches the narrowing cavity 812, the tightening of the narrowing cavity 812 acts on the conveyor belt 500. The conveyor belt 500 squeezes the shrimp body through friction, so that the shrimp meat slides out of the shrimp shell, and the shrimp meat comes out from the discharge port 820. The conveyor belt 500 takes away the shrimp shell to obtain peeled shrimp meat. There is no need to accurately locate the position of each shrimp body. The device has the advantages of simple structure and high production efficiency.

[0043] In this embodiment, combined with Figure 3 and Figure 4 As shown, the longitudinal section of the first channel 610 is U-shaped, that is, the interior of the clamping frame 600 is provided with a first side wall surface 630 and a second side wall surface 640, the first side wall surface 630 and the second side wall surface 640 are arranged relative to each other to define the first channel 610, the first side wall surface 630 is parallel to the second side wall surface 640, and the bottom end of the first side wall surface 630 and the bottom end of the second side wall surface 640 are connected by an arc wall surface 650, so that the first side wall surface 630, the second side wall surface 640 and the arc wall surface 650 form a U-shaped first channel 610. The first conveying wheel 300 and the second conveying wheel 400 tighten the conveying belt 500, and the shrimp body is placed flat on the conveying belt 500. When conveyed to the clamping frame 600, the first side wall surface 630 and the second side wall surface 640 can clamp the flat shrimp body in a vertical direction and convey it along with the conveying belt 500. In addition, when the shrimp body is squeezed by the conveying belt 500, it will be straightened, which is convenient for cutting the back or opening the belly. The shrimp body can be clamped in a directional vertical state such as back up, belly down or back down, belly up for positioning and conveying, providing an accurate positioning posture for the back opening, intestine picking and other operations of shrimp processing. The conveying belt 500 is a soft flat belt, such as a PVC belt, a nylon belt, etc.

[0044] As another equivalent embodiment, Figure 5 As shown, the longitudinal section of the first channel 610 is V-shaped, that is, the first side wall 630 and the second side wall 640 are provided inside the clamping frame 600, and the bottom ends of the first side wall 630 and the second side wall 640 are inclined toward the inner side of the first channel 610 to define a V-shape, so the conveyor belt 500 is also limited to bend upward into a V-shape. Because the width of the 1st to 5th sections of the shrimp body is larger than the width of the 6th to 7th sections, and the first channel 610 is set to be a V-shape with a narrower bottom end, the conveyor belt 500 clamps and straightens the 1st to 5th sections of the shrimp body. The extrusion of the shrimp body will cause the 6th to 7th sections of the tail to bend in the direction of the natural bending of the shrimp body, so that the 6th to 7th sections of the shrimp body with a smaller width are bent downward and located at the bottom of the V-shaped conveyor belt 500, as can be seen Fig.10 Therefore, when the shrimp body passes through the cutting assembly 700, only the 1st to 5th sections of the shrimp body are cut, while the 6th to 7th sections of the shrimp body are bent down into the bottom of the V-shaped conveyor belt 500 and are not cut. The boundary between the cutting and non-cutting of the shrimp shell of the shrimp body is between the 5th and 6th sections, which is not an absolutely accurate boundary, so that the back-opened prawn product with the 6th to 7th sections of the shrimp shell retained can be processed in the subsequent shelling stage.

[0045] As a third equivalent embodiment, combined with Figure 6 and Figure 7 As shown, observing along the longitudinal section of the first channel 610, the first channel 610 includes a first cavity 611 and a second cavity 612 which are connected in sequence from top to bottom, the width of the first cavity 611 remains basically consistent from top to bottom, the width of the second cavity 612 gradually decreases from top to bottom, the first cavity 611 formed by the upper half of the first side wall surface 630 and the upper half of the second side wall surface 640 is similar to a U-shape, and the second cavity 612 formed by the lower half of the first side wall surface 630 and the lower half of the second side wall surface 640 is similar to a V-shape, thereby defining the first channel 610 as a U-V shape. Therefore, the conveyor belt 500 is also limited to bend upward into a U-V shape, because the width of the 1st to 5th sections of the shrimp body is larger than the width of the 6th to 7th sections, and the first channel 610 is set to be a V-shape with a narrower bottom end, so the conveyor belt 500 clamps the 1st to 5th sections of the shrimp body, and the shrimp body is squeezed to make the 6th to 7th sections of the tail bend in the direction of the natural bending of the shrimp body, so that the 6th to 7th sections of the shrimp body with a smaller width bend downward and are located at the bottom of the U-V-shaped conveyor belt 500, that is, located in the second cavity 612, which can be seen Fig.10 As shown. The width of the first cavity 611 of the first channel 610 is relatively large, so it can accommodate a larger shrimp body and fit the shape of the shrimp body more closely, further expanding the range of shrimp species that can be processed. Therefore, when the shrimp body passes through the cutting assembly 700, only the 1st to 5th sections of the shrimp body are cut, while the 6th to 7th sections of the shrimp body are bent down into the bottom of the U-V-shaped conveyor belt 500 and are not cut. The boundary between cutting and not cutting the shrimp shell of the shrimp body is between the 5th and 6th sections, which is not an absolutely accurate boundary, so that the back-opened prawn product with the 6th to 7th sections of the shrimp shell retained can be processed in the subsequent shelling stage.

[0046] In this embodiment, if Figure 4 As shown, the top of the first side wall 630 is provided with a first top wall 660 extending toward the inner side of the first channel 610, and the top of the second side wall 640 is provided with a second top wall 670 extending toward the inner side of the first channel 610, so as to surround the first channel 610 and prevent the rotating cutting assembly 700 from carrying away the shrimp body during the cutting process.

[0047] The first top wall surface 660 and the second top wall surface 670 are both extended obliquely upward on the inner side of the first channel 610, so that the combination of the first top wall surface 660 and the second top wall surface 670 is in an eight-shaped shape, so that the first channel 610 has a larger conveying area to accommodate shrimp bodies, thereby improving the processing capacity of larger shrimp bodies.

[0048] In this embodiment, if Figure 3 As shown, the length of the processing opening 620 is less than the length of the support body, the width of the processing opening 620 is less than the width of the first channel 610, and the processing opening 620 is surrounded from front to back, left to right, to ensure that the cutting assembly 700 only cuts the shrimp body and does not affect the transportation of the shrimp body, to prevent the shrimp body from escaping from the top opening of the shelling rack 800 during the cutting process. The processing opening 620 is rectangular, which is convenient for accommodating the circular cutting blade 760, and the height of the first channel 610 is greater than the width of the first channel 610, to ensure that the shrimp body can be clamped in a vertical state for transportation.

[0049] In this embodiment, if Figure 8 and Fig. 9 As shown, the limiting cavity 811 is connected to the narrowing cavity 812 through a guide surface 830, and the guide surface 830 is gradually inclined upward from the back to the front. After the shrimp body is cut, the shrimp body continues to be transported, and when passing through the connection between the limiting cavity 811 and the narrowing cavity 812, the guide surface 830 transitions to the narrowing cavity 812, and the shrimp body is squeezed and squeezed out. Under the action of inertia force, the shrimp meat pops up along the gradually inclined guide surface 830 and is transported out through the discharge port 820, and the finished shrimp meat can be collected.

[0050] Among them, the shelling rack 800 is provided with a third side wall 840, a fourth side wall 850, a fifth side wall 860 and a sixth side wall 870 inside, the third side wall 840 and the fourth side wall 850 are arranged opposite to each other to form a limiting cavity 811, the fifth side wall 860 and the sixth side wall 870 are arranged opposite to each other to form a narrowing cavity 812 communicated with the limiting cavity 811, the third side wall 840 and the fifth side wall 860, the fourth side wall 850 and the sixth side wall 870 are connected by the guide surface 830, the guide surfaces 830 on both sides have a tightening effect on the left and right sides of the conveyor belt 500, so as to improve the shelling ability of the cut shrimp bodies, and the width of the narrowing cavity 812 only allows the conveyor belt 500 folded in half to pass through. The length of the discharge port 820 is smaller than the length of the limiting cavity 811, so that the front and rear ends of the discharge port 820 are surrounded, ensuring that the shrimp meat can only come out of the discharge port 820. The height of the limiting cavity 811 and the narrowing cavity 812 are equal, ensuring that the conveyor belt 500 can pass through the second channel 810 in the horizontal direction.

[0051] Furthermore, the guide surface 830 can be a circular arc surface for transition connection, so that the conveyor belt 500 can be transitionally squeezed. The guide surface 830 can also be a plane to directly form a stepped structure shape, which is set according to the variety of shrimp products to be processed.

[0052] In this embodiment, combined with Figure 1 As shown, the discharge port 820 is provided with a guide plate 880 for guiding the collection direction of the shrimp bodies. After the shrimp meat is shelled, it comes out of the discharge port 820 and has an inertial force to move forward. The guide plate 880 blocks and guides the shrimp bodies to one side of the shelling rack 800 for collection.

[0053] Furthermore, a collecting plate 890 is provided on the side of the shelling rack 800, and the shrimp meat is transported to the collecting bucket through the collecting plate 890 to achieve the collection of the shrimp meat.

[0054] In this embodiment, it also includes a support plate 900 installed on the frame 100, and the support plate 900 is located between the first conveying wheel 300 and the second conveying wheel 400. The shelling frame 800 and the clamping frame 600 are arranged on the support plate 900 along the front and rear sides. The position of the conveyor belt 500 that is bent upward can be changed by adjusting the position of the support plate 900.

[0055] In this embodiment, if Figures 10 to 13 As shown, the cutting assembly 700 includes: a first transmission wheel 710, a connecting plate 720, a second transmission wheel 730, a transmission belt 750 and a cutting blade 760, the first transmission wheel 710 is connected to the output end 210 of the driving member 200; one end of the connecting plate 720 is rotatably connected to the output end 210 of the driving member 200 through a bearing seat, the second transmission wheel 730 is rotatably connected to the other end of the connecting plate 720, the transmission belt 750 is transmission-connected between the first transmission wheel 710 and the second transmission wheel 730, and the cutting blade 760 is installed on the second transmission wheel 730. The cutting blade 760 is driven to cut by transmission. The connecting plate 720 is rotatably connected to the output end 210 of the driving member 200. The cutting blade 760 can rotate slightly along the output end 210 of the driving member 200 as the center. During the cutting process, it can automatically float up and down freely according to the size and height of the shrimp body, ensuring that the cutting process is not affected by the size of the shrimp body, and fixed depth cutting can be achieved to open the back or abdomen.

[0056] In order to ensure that the shrimp bodies can be cut during transportation, the rotation speed of the cutting disc 760 and the conveying speed of the conveyor belt 500 need to have a certain difference, the blade linear speed of the cutting disc 760 is higher than the transmission speed of the conveyor belt 500, or the rotation direction of the cutting disc 760 is directly opposite to the conveying direction of the conveyor belt 500.

[0057] In this embodiment, a structure is adopted in which the rotation direction of the cutting blade 760 is opposite to the conveying direction of the conveyor belt 500, and the same driving member 200 is used to simultaneously realize the operation of the conveyor belt 500 and the cutting blade 760, and the structure is simpler and more compact. Among them, the transmission belt 750 includes a first transmission section 751 and a second transmission section 752 connected in sequence from head to tail, the first transmission section 751 and the second transmission section 752 are both transmission-connected to the first transmission wheel 710 and the second transmission wheel 730, and the first transmission section 751 and the second transmission section 752 are cross-arranged in the area between the first transmission wheel 710 and the second transmission wheel 730, that is, the reverse cutting relative to the conveyor belt 500 is achieved by cross-arranging the transmission belt 750, which has a better cutting effect.

[0058] It is understandable that the operation of the conveyor belt 500 and the cutting blade 760 may also be controlled by different driving sources, and the present invention is not limited thereto.

[0059] In this embodiment, the second transmission wheel 730 is provided with a rotating shaft 740 connected to the cutting blade disc 760, and the other end of the connecting plate 720 is rotatably connected to the rotating shaft 740 via a bearing seat. The cutting blade disc 760 includes a first limiting plate 761, a first pad 762, a cutting blade 763, a second pad 764 and a second limiting plate 765 which are sequentially arranged along the axial direction of the rotating shaft 740. The diameter of the first limiting plate 761 and the diameter of the second limiting plate 765 are both larger than the diameter of the first pad 762 and the diameter of the second pad 764, so that the outer edges of the first limiting plate 761, the second limiting plate 765, the first pad 762 and the second pad 764 form an annular groove 766 for accommodating the object to be cut. During the cutting process, the shrimp body will enter the annular groove 766, the first pad 762 and the second pad 764 will abut against the shrimp body, the first pad 762 and the second pad 764 will be detachably connected to the rotating shaft 740, the diameter of the cutting knife 763 is larger than the diameter of the first pad 762 and the diameter of the second pad 764, so that the blade of the cutting knife 763 extends to the annular groove 766, and the width of the protruding blade of the cutting knife 763 relative to the annular groove 766 is the cutting depth of the shrimp body, thereby achieving fixed depth cutting of the shrimp body. Moreover, by replacing the first pad 762 and the second pad 764 of different specifications, the cutting depth of the cutting knife disc 760 can be changed, and the application range is wider.

[0060] Further, one end of the rotating shaft 740 is connected to the second transmission wheel 730, and the other end of the rotating shaft 740 is detachably provided with a fixing block 767, the first limiting plate 761 is fixedly provided on the rotating shaft 740, the second limiting plate 765 is detachably connected to the rotating shaft 740, and the second limiting plate 765 abuts against the fixing block 767. The installation position of the second limiting plate 765 is adjusted by the fixing block 767, so that the second limiting plate 765 is pressed toward the first limiting plate 761, and the first pad 762 and the second pad 764 are clamped, so that the cutting blade 760 can be quickly disassembled and installed. Among them, the fixing block 767 is threadedly connected to the rotating shaft 740, which is convenient for disassembly and assembly, and has good stability.

[0061] Furthermore, the diameter of the cutting knife 763 is smaller than the diameter of the first limiting plate 761 and the diameter of the second limiting plate 765, that is, the blade of the cutting knife 763 is surrounded by the annular groove 766, which plays a protective role, is safer, and avoids accidental injury to the operator during the work process. In addition, the diameter of the first limiting plate 761 is equal to the diameter of the second limiting plate 765, which is convenient for limiting the left and right sides of the shrimp body. The diameter of the first pad 762 is equal to the diameter of the second pad 764, which ensures that the back of the shrimp body can support the first pad 762 and the second pad 764 at the same time, so as to better lift the cutting knife disc 760 and realize the effect of free floating up and down.

[0062] Furthermore, the first gasket 762 is provided with a first arc surface 768 recessed inwardly on the side close to the cutting knife 763, and the second gasket is provided with a second arc surface 769 recessed inwardly on the side close to the cutting knife 763, so that the longitudinal section of the shape formed by the combination of the first arc surface 768 and the second arc surface 769 is similar to a semicircular arc, which better fits the arc shape of the back of the shrimp body, improves the cutting stability, and ensures the cutting quality.

[0063] The working principle of the shrimp peeling equipment described in this embodiment is as follows: the shrimp body is placed on the conveyor belt 500, and when passing through the first channel 610, the shrimp body is clamped in a vertical posture for transportation. When passing through the processing port 620, the shrimp body lifts up the cutting knife disc 760 to float up and down, and the middle of the back of the shrimp body is cut by the cutting knife 763. After the cutting is completed, the shrimp body is continued to be carried to the shelling rack 800 by the conveyor belt 500. When passing through the narrowing cavity 812, the conveyor belt 500 squeezes the shrimp body, and the shrimp meat is squeezed out by the belt and comes out from the upper discharge port 820 to obtain the shelled open-back shrimp, which falls into the shrimp meat collection bucket through the guide plate 880, and the shrimp shell is clamped by the conveyor belt 500 and passes through the narrowing cavity 812. Finally, as the conveyor belt 500 is flattened, the shrimp shell falls.

[0064] In summary, the above-mentioned embodiments of the present invention provide a shrimp peeling device having the following advantages: (1) by utilizing the cooperation between the conveyor belt 500 and the first channel 610, the shrimp body can be conveyed in a vertical state; (2) the connecting plate 720 can realize the up and down floating of the cutting blade 760, and the cutting process is not affected by the size difference of the shrimp body, and fixed depth cutting can be achieved; (3) the cutting blade depth can be adjusted by the replaceable first pad 762 and the second pad 764; (4) by utilizing the tightening effect of the narrowing cavity 812 on the conveyor belt 500, the cut shrimp body can be squeezed to obtain shelled shrimp; (5) the whole process does not require the shrimp body to be positioned, the structure is simple, the manufacturing cost is low, and the production efficiency can be greatly improved.

[0065] The above description 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.
