Description

Technical Field

[0001] The invention relates to the technical field of shrimp processing equipment, and in particular to a novel shrimp cutting equipment capable of improving the quality and efficiency of shrimp cutting. Background Art

[0002] In the traditional aquatic product processing industry, shrimps are mainly cut by manual labor. This operation method results in high labor intensity and low work efficiency for workers. At the same time, workers are easily scratched by cutting tools and stabbed by shrimp shells. In response to the above situation, some automatic shrimp cutting equipment has appeared on the market. For example, the Chinese utility model patent document with authorization announcement number CN207678775U discloses a shrimp back cutting equipment. Another example is the safe and easy-to-use shrimp back cutting and shrimp line cleaning equipment disclosed in the Chinese invention patent application document with application publication number CN110692696A. Both of these devices realize intelligent shrimp cutting by setting up an automatic cutting structure, which greatly reduces the labor intensity of workers, improves processing efficiency, and meets market demand.

[0003] However, with the use of shrimp cutting equipment, more and more problems began to emerge. The above equipment has improved the efficiency of cutting shrimp bodies, but the quality of shrimp after cutting the shrimp bodies is poor, far inferior to the quality of shrimp after manual cutting. Taking the safe and easy-to-use shrimp back cutting and shrimp body cleaning equipment disclosed in the Chinese invention patent application document with application publication number CN110692696A as an example, the shrimp enters the adjustment groove, moves forward under the pressure of the roller, and is cut under the action of the cutter. Since the shrimp back is relatively smooth, in order to enable the roller to stably support the shrimp to move forward, the roller is densely covered with sharp thorns that can penetrate into the shrimp back, but the shrimp's abdomen is prone to horizontal slippage, especially when there is more water in the adjustment groove, the tilting phenomenon caused by the shrimp's abdominal slippage is more obvious. Since the upper shrimp back is pierced by the sharp thorns, the shrimp back cannot be fine-tuned with the movement of the shrimp's abdomen. Therefore, the accuracy of shrimp cutting after position displacement is reduced, and the quality deteriorates accordingly.

[0004] In addition, the greater pressing force provided by the spikes on the roller also increases the resistance to the movement of the shrimp and reduces the efficiency of shrimp cutting. The reduction in shrimp cutting efficiency can also be explained by the Chinese utility model patent document with authorization announcement number CN207678775U, which discloses a shrimp back cutting device. After the shrimp is cut by a disc knife (also known as a cutting knife), it flows out along the placement groove. Since the width of the placement groove is fixed, the width requirement of the shrimp to be processed is also fixed. Once shrimp with a larger width is processed, it is easily squeezed and deformed by the side wall of the placement groove, causing damage. The only option is to replace the shrimp cutting device with a placement groove of matching specifications and sizes. This not only reduces the efficiency of shrimp processing, but also requires the shrimp cutting site to reserve shrimp cutting devices of different specifications, resulting in excessive cost investment.

[0005] It can be seen that all kinds of shrimp cutting equipment on the market have certain problems to a greater or lesser extent. With the in-depth research on shrimp cutting equipment, the improvement points are no longer limited to the initial consideration of reducing the intensity of manual labor, but on this basis, it is necessary to fully guarantee the quality of shrimp and ensure that the shrimp cutting equipment causes the least damage to the shrimp while cutting the shrimp body. Therefore, how to improve the quality of shrimp cutting while ensuring the efficiency of shrimp cutting has become a technical problem that needs to be solved urgently by technicians in this field. Summary of the invention

[0006] In view of this, the purpose of the present invention is to provide a new shrimp cutting equipment with improved shrimp cutting quality and efficiency, so as to solve the technical problems of poor shrimp cutting quality and low processing efficiency existing in the shrimp cutting equipment in the prior art.

[0007] To achieve the above-mentioned purpose, the novel shrimp cutting equipment provided by the present invention for improving the quality and efficiency of shrimp cutting adopts the following technical solutions:

[0008] New shrimp cutting equipment that improves shrimp cutting quality and efficiency, including:

[0009] The shrimp-introducing pressing wheel is rotatably arranged on the shrimp's travel path. The surface of the shrimp-introducing pressing wheel has no sharp thorns and is used to press on the shrimp's back;

[0010] Shrimp feeding roller teeth, which are arranged on the shrimp's travel path, correspond to the shrimp feeding pressing wheel in the up-down direction, and are used to press on the shrimp's abdomen to cooperate with the shrimp feeding pressing wheel to correct the shrimp's posture;

[0011] A feeding power mechanism, the feeding power mechanism is connected to the shrimp feeding roller teeth, and the feeding power mechanism is used to provide a feeding force for the shrimp through the shrimp feeding roller teeth;

[0012] The cutter structure is defined as the shrimp moving from the back to the front, the cutter structure is arranged at the front side of the shrimp feeding roller teeth, the cutter structure has a cutter for cutting the shrimp body, and the radial sides of the cutter structure have an open shrimp outlet area without a stop structure;

[0013] A cutter power mechanism, the cutter power mechanism is coupled to the cutter structure, and the cutter power mechanism is used to drive the cutter structure to rotate to provide cutting force;

[0014] A sensor is arranged on the shrimp inlet seat or beside the shrimp inlet pressure wheel or beside the shrimp inlet roller teeth, and is used to detect the shape characteristics of the shrimp;

[0015] A central controller is connected to the sensor through a signal and controls the feed power mechanism and the cutter power mechanism. The central controller is used to run corresponding control logic and control the feed power mechanism and the cutter power mechanism to work according to the shape characteristics of the shrimp identified by the sensor.

[0016] The novel shrimp cutting device for improving the quality and efficiency of shrimp cutting provided by the present invention has the following beneficial effects: during the shrimp's travel, the shrimp feeding pressure wheel corrects and limits the shrimp's back, the shrimp feeding roller teeth limit the shrimp's abdomen, and the feeding power mechanism provides feeding force for the shrimp feeding roller teeth, thereby driving the shrimp to run; the sensor transmits the detected shrimp's body features to the central controller, and the central controller controls the feeding power mechanism and the cutting knife power mechanism to work according to the identified shrimp's body features, and the cutting knife power mechanism is used to control the cutting knife structure to cut the shrimp body;

[0017] The present invention mainly relies on the shrimp-feeding roller teeth to penetrate into the shrimp's abdomen to achieve the positioning of the shrimp. Compared with the smooth and hard shrimp back, the shrimp's abdomen is rougher and softer due to the presence of shrimp legs. Therefore, the pressing force required for the shrimp-feeding roller teeth to penetrate into the shrimp's abdomen is relatively small. The squeezing force of the shrimp-feeding roller teeth and the thornless shrimp-feeding pressure wheel on the shrimp is greatly reduced, reducing the damage to the shrimp and improving the quality of shrimp cutting. In addition, since the shrimp-feeding roller teeth fit the shrimp's abdomen, the slippage of the shrimp's abdomen is hindered. Even if the shrimp's abdomen is slightly deflected, the shrimp-feeding pressure wheel can rely on its own smooth surface to effectively fit the shrimp's back to adaptively adjust the shrimp's posture and ensure the quality of shrimp cutting. The open shrimp outlet areas on both sides of the radial direction of the cutter structure fully avoid the squeezing and blocking of the shrimp, that is, reduce the squeezing damage to the shrimp, so that the entire device can adaptively process shrimps of various sizes, effectively improving the efficiency of shrimp cutting. In summary, compared with the prior art, the present invention effectively solves the technical problems of poor shrimp cutting quality and low processing efficiency in the prior art of shrimp cutting equipment.

[0018] Furthermore, the shrimp-feeding pressing wheel includes two circular plates, which are arranged at intervals in the left-right direction, connected by a rotating shaft, and the rotating shaft and each of the circular plates are rotatably matched, and each of the circular plates has a convex portion on one side facing the other circular plate, and the two convex portions and the two circular plates form a V-shaped surface for pressing the shrimp back. The V-shaped surface is more adapted to the contour of the shrimp back, and the pressing and positioning effect is better.

[0019] Furthermore, the rotating shaft is connected to a swing arm, and the novel shrimp cutting device for improving the quality and efficiency of shrimp cutting comprises a mounting plate located beside the swing arm, and the swing arm is rotatably mounted on the mounting plate. The shrimp inlet pressing wheel can not only rotate relative to the shrimp, but also be linked with the shrimp body through the swing arm to better adapt to the adjustment of different postures caused by different shrimp body sizes, and the pressure contact positioning effect is better.

[0020] Furthermore, the feeding power mechanism comprises a feeding motor, which is fixed on the mounting plate, and an output shaft of the feeding motor is connected to a linkage shaft, a roller is fixed on the linkage shaft, and the shrimp feeding roller teeth are densely distributed around the circumference of the roller.

[0021] Furthermore, two anti-slip plates are fixed on the linkage shaft, and the two anti-slip plates are respectively located on both sides of the axial direction of the roller, each anti-slip plate fits the roller, and the radial dimension of the anti-slip plate is smaller than the radial dimension of the roller, so that the side of the roller forms the open shrimp outlet area. The anti-slip plates fully ensure the stability of the roller.

[0022] Furthermore, the cutter structure includes a cutter, a connecting shaft is connected to the middle of the cutter, and the cutter power mechanism includes a cutter motor fixed on the mounting plate, an output shaft of the cutter motor is connected to a central shaft, and the central shaft and the connecting shaft are matched through a belt drive. The belt drive can be used for transmission with a large center distance between the two shafts; and the belt is elastic, which can alleviate impact and vibration loads, and the operation is stable and noiseless.

[0023] Furthermore, a movable mounting seat is mounted on the mounting plate, the output shaft of the cutter motor is rotatably mounted inside the mounting seat, a cutting control mechanism for driving the mounting seat is arranged outside the mounting seat, and the cutting control mechanism is used to control the cutter to approach or move away from the shrimp feeding roller teeth by controlling the mounting seat. By adjusting the distance between the cutter and the shrimp feeding roller teeth, it can better meet the cutting requirements of shrimps with different cutting depths and different cutting methods, and further improve the adaptability and quality of shrimp cutting.

[0024] Furthermore, the mounting seat includes a cylinder and a seat body, the cylinder is eccentrically arranged, the cylinder is used to be inserted into the mounting plate and rotatably cooperate with the mounting plate, the cutting control mechanism is a cutting control motor, the output shaft of the cutting control motor and the cylinder are driven by a belt drive, and the connecting shaft, the rotating shaft and the output shaft of the cutter motor are rotatably assembled in the seat body.

[0025] Furthermore, the central controller controls the connection of the cutting control mechanism, so that the central controller drives the cutting control mechanism according to the shape characteristics of the shrimp identified by the sensor, and then controls the distance and time of the cutter on the mounting seat approaching or moving away from the shrimp feeding roller teeth. The cutting length of the shrimp body is determined by the timing of the cutter approaching and moving away from the shrimp feeding roller teeth. During the movement of the shrimp, the sensor detects the shape characteristics of the shrimp in real time and transmits a signal to the central controller. The central controller determines the timing of the cutting control mechanism driving the cutter to approach and move away from the shrimp feeding channel according to the received sensor signal. The timing can be the distance or time of the shrimp movement. When the timing comes, the central controller controls the cutting control motor, and drives the cutter to approach or move away from the shrimp feeding roller teeth through the action of the mounting seat, thereby achieving the cutting of the preset length. In this way, the shrimp body cutting accuracy is higher and the shrimp cutting quality is higher.

[0026] Furthermore, shrimp-blocking blocks are arranged in the extension direction of the shrimp-feeding roller teeth, and the shrimp-blocking blocks are used to make the shrimps fall off the shrimp-feeding roller teeth after contacting the shrimps. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0042] The applicant believes that the continuous optimization and improvement of the shrimp cutting equipment, in addition to the observation and research on the shrimp cutting equipment itself, must also start from the physical characteristics of the shrimp, and analyze the force and operating conditions of the shrimp in the shrimp cutting equipment according to the shrimp's morphology, so that the shrimp cutting equipment can better adapt to the processing of shrimp, thereby improving the quality and efficiency of shrimp cutting.

[0043] Based on the above considerations, the applicant observed the physical characteristics of shrimps such as Figure 1 As shown in the figure, the shrimp includes a back on the upper part and legs on the lower part. The back is relatively smooth and hard, and the legs are arranged in two rows. The middle of the legs is a relatively rough and soft belly. Based on this observation, the applicant found that the roller in the prior art mainly uses the following method: Figure 2 The arrangement shown can penetrate into the shrimp's back with spikes to position and transport the shrimp, but the shrimp's abdomen is prone to horizontal slippage, especially when there is more water in the adjustment tank, the tilting phenomenon caused by the shrimp's abdomen slipping is more obvious. Since the upper part of the shrimp's back is pierced by the spikes, the shrimp's back cannot be fine-tuned as the shrimp's abdomen moves. Therefore, the shrimp's centering ability is reduced when the shrimp body is cut after the position is shifted, and the quality deteriorates accordingly.

[0044] At the same time, the spikes on the roller need to break through the shrimp shell and penetrate into the shrimp body, which requires a large amount of pressing force. Therefore, the squeezing phenomenon on the shrimp is particularly obvious, which seriously affects the shrimp cutting effect.

[0045] In addition, the applicant has also found through observation that in some shrimp cutting devices, such as Figure 3As shown, after being cut by the cutting knife, the shrimp flows out along the placement groove. Since the width of the placement groove is fixed, the width requirement of the shrimp to be processed is also fixed. Once shrimps with a larger width are processed, they are easily squeezed and deformed by the side wall of the placement groove, causing damage. The only option is to replace the shrimp cutting equipment with a placement groove of matching specifications and sizes. This not only reduces the efficiency of shrimp processing, but also requires the shrimp cutting site to stock shrimp cutting equipment of different specifications, resulting in excessively high costs.

[0046] The above two phenomena are common problems that affect the quality and efficiency of shrimp cutting in existing shrimp cutting equipment. The technical solution of the present application mainly focuses on improving the above two phenomena to improve the quality and efficiency of shrimp cutting.

[0047] The first embodiment of the novel shrimp cutting device for improving shrimp cutting quality and efficiency provided by the present invention:

[0048] like Figures 4 to 6 As shown, a novel shrimp cutting device for improving the quality and efficiency of shrimp cutting comprises a shrimp feeding seat 1, on which a shrimp feeding channel 2 is arranged, and the shrimp feeding channel 2 is used for preliminary guidance of shrimps; it is defined that the shrimps move from back to front, and a shrimp feeding pressing wheel is rotatably arranged in front of the shrimp feeding channel 2, and the surface of the shrimp feeding pressing wheel has no spikes and is used to press on the back of the shrimp; specifically, the shrimp feeding pressing wheel comprises two circular plates 10, which are arranged at intervals in the left and right directions, and the two circular plates 10 are connected by a rotating shaft 11, and the rotating shaft 11 is rotatably matched with each of the circular plates 10, and each of the circular plates 10 has a protrusion 12 on one side facing the other circular plate 10, and the two protrusions 12 and the two circular plates 10 form a V-shaped surface for pressing on the back of the shrimp. The V-shaped surface is more adapted to the contour of the shrimp back, and the pressure contact positioning effect is better. In other embodiments, the side of each circular plate facing the other circular plate may also not have a raised portion, that is, an H-shaped surface is formed between the two circular plates 10; in addition, the above-mentioned shrimp pressing wheel is a split structure, and during actual processing, it can also be an integrated structure, by placing a round rod on a lathe for processing, and turning a V-shaped surface on its circumference.

[0049] In other embodiments, the shrimp inlet seat may also be replaced by a conveying device such as a conveyor belt.

[0050] The rotating shaft 11 is connected to a swing arm 13. The new shrimp cutting equipment for improving the quality and efficiency of shrimp cutting includes a mounting plate 14 located beside the swing arm 13. The swing arm 13 is rotatably mounted on the mounting plate 14. Specifically, a mounting column 15 is fixed to the side of the mounting plate 14 facing the swing arm 13. The swing arm 13 is rotatably mounted on the mounting column 15. The shrimp inlet pressing wheel can not only rotate relative to the shrimp, but also be linked with the shrimp body through the swing arm 13 to better adapt to the adjustment of different postures caused by different sizes of the shrimp body, and the pressure-touch positioning effect is better. In other embodiments, the mounting column may not be used. In this case, the position of the mounting plate is moved forward and directly rotatably assembled with the swing arm.

[0051] like Figure 4 and Figure 5 As shown, a shrimp feeding roller tooth 4 is also arranged on the front side of the shrimp feeding channel 2. The shrimp feeding roller tooth 4 corresponds to the shrimp feeding pressure wheel in the up and down directions. The shrimp feeding roller tooth 4 is used to press on the abdomen of the shrimp to cooperate with the shrimp feeding pressure wheel to correct the posture of the shrimp. The shrimp feeding roller tooth 4 is driven by a feeding power mechanism to provide feeding force for the shrimp; specifically, the feeding power mechanism includes a feeding motor 16, which is fixed on the mounting plate 14, and the output shaft of the feeding motor 16 is connected to a linkage shaft 17, on which a roller 18 is fixed, and the circumference of the roller 18 is densely covered with shrimp feeding roller teeth 4.

[0052] In order to ensure the stability of the roller 18, two anti-slip plates 19 are fixed on the linkage shaft 17. The two anti-slip plates 19 are respectively located on both sides of the axial direction of the roller 18. Each anti-slip plate 19 fits the roller 18. The radial dimension of the anti-slip plate 19 is smaller than the radial dimension of the roller 18, so that the side of the roller 18 forms the open shrimp outlet area 6. The anti-slip plate 19 fully ensures the stability of the roller 18. In other embodiments, when the stability of the connection between the roller and the linkage shaft meets the use requirements, the anti-slip plate may not be provided.

[0053] like Figure 4 , Figure 5 and Figure 7 As shown, a cutter structure is arranged on the front side of the shrimp feeding roller teeth 4, and the cutter structure has a cutter 5 for cutting the shrimp body. The radial sides of the cutter structure have an open shrimp outlet area 6 without a stop structure. The cutter structure is driven by a cutter power mechanism to provide cutting force for the shrimp; specifically, the cutter structure includes a cutter 5, and a connecting shaft 20 is connected to the middle of the cutter. The cutter power mechanism includes a cutter motor 21 fixed on the mounting plate 14, and the output shaft of the cutter motor 21 is connected to a transfer shaft 31. The transfer shaft 31 and the connecting shaft 20 are matched through a belt drive. Belt drive can be used for transmission with a large center distance between the two shafts; and the belt is elastic, which can alleviate impact and vibration loads, and the operation is stable and noiseless. In other embodiments, the belt drive can also be replaced by a chain drive and a gear drive.

[0054] like Figure 4 and Figure 5 As shown, a shrimp blocking block 7 is also provided in the extension direction of the shrimp feeding roller teeth 4, and the shrimp blocking block 7 is used to make the shrimp fall off from the shrimp feeding roller teeth 4 after contacting the shrimp.

[0055] Sensors are also arranged on the shrimp inlet seat 1 or on the side of the shrimp inlet pressure wheel or on the side of the shrimp inlet roller teeth 4. The sensors are used to detect the body characteristics of the shrimp, such as Figure 8 As shown, since an open shrimp outlet area 6 is formed beside the shrimp inlet roller teeth 4, there are many optional positions for the sensor detection points 8, which facilitates the installation of the sensor.

[0056] In this embodiment, the entire shrimp cutting equipment also includes a central controller (not shown in the figure), which is connected to the sensor by signal and controls the feed power mechanism and the cutter power mechanism. The central controller is used to run the corresponding control logic and control the feed power mechanism and the cutter power mechanism to work according to the shape characteristics of the shrimp identified by the sensor.

[0057] like Figure 4 and Figure 5 As shown, a movable mounting seat 22 is mounted on the mounting plate 14, and the output shaft of the cutter motor 21 is rotatably mounted inside the mounting seat 22. A cutting control mechanism for driving the mounting seat 22 to move is arranged outside the mounting seat 22, and the cutting control mechanism is used to control the cutter 5 to approach or move away from the shrimp feeding roller teeth 4 by controlling the mounting seat 22. By adjusting the distance between the cutter 5 and the shrimp feeding roller teeth 4, it can better adapt to the cutting requirements of shrimps with different cutting depths and different cutting methods, and further improve the adaptability and quality of shrimp cutting. Specifically, the mounting seat 22 includes a cylinder 23 and a seat 24, the cylinder 23 is eccentrically arranged, and the cylinder 23 is used to be inserted into the mounting plate 14 and rotate with the mounting plate 14. The cutting control mechanism is a cutting control motor 25, and the output shaft of the cutting control motor 25 and the cylinder 23 are driven by a belt drive, and the output shaft of the cutter motor 21 is rotatably mounted in the seat 24. In other embodiments, the output shaft of the cutting control motor and the cylinder can also be chain driven or gear driven or driven by a connecting rod structure. For the convenience of arrangement, a connecting shaft 20 and a rotating shaft 31 are rotatably mounted in the seat body 24 .

[0058] The central controller also controls the connection cutting control mechanism, so that the central controller drives the cutting control mechanism according to the shape characteristics of the shrimp identified by the sensor, thereby controlling the distance and time of the cutter 5 on the mounting seat 22 approaching or moving away from the shrimp feeding roller teeth 4. The specific control process is as follows Fig. 9 and 10 As shown, it should be noted that, in addition to scanning the physical features of the shrimp through the sensor, the device is also provided with an interactive end, and the user can also manually input the shrimp cutting parameters to the central controller through the interactive end, and then set the length parameters and other information required to cut the shrimp. The cutting length of the shrimp body is determined by the timing of the cutter 5 approaching and moving away from the shrimp feeding roller teeth 4. During the movement of the shrimp, the sensor detects the physical features of the shrimp in real time and transmits a signal to the central controller. The central controller calculates according to the received sensor signal and the length parameter set by the user, so as to determine the timing of the cutting control mechanism driving the cutter 5 to approach and move away from the shrimp feeding channel 2. The timing can be the distance or time of the shrimp. When the time comes, the central controller controls the cutting control motor 25, and drives the cutter 5 to approach or move away from the shrimp feeding roller teeth 4 through the action of the mounting seat 22, thereby achieving a preset length of cutting. In this way, the shrimp body cutting accuracy is higher and the shrimp cutting quality is higher.

[0059] In addition, the reason for setting the cutting control motor 25 is also due to the problem of shrimp cutting depth, that is, the depth may not be a fixed value, but may be a variable depth. For example, an oblique line may be cut when viewed from the side, or it may be cut along the curve of the shrimp body. On this basis, it is very necessary to control the distance and time of the cutter 5 approaching or moving away from the shrimp feeding roller teeth 4.

[0060] The working principle of the novel shrimp cutting device for improving the quality and efficiency of shrimp cutting provided by the present invention is as follows: the machine is powered on, the central controller and the sensor are started, and the cutter motor 21, the feed motor 16 and the cutting control motor 25 are also started; the shrimp is put into the shrimp feeding channel 2 from the shrimp feeding seat 1, and runs from the back to the front, the shrimp feeding pressure wheel limits the shrimp back, the shrimp feeding roller teeth 4 limit the shrimp abdomen, and the feeding power mechanism provides a feeding force for the shrimp feeding roller teeth 4, thereby driving the shrimp to run from the back to the front; the sensor transmits the detected shrimp shape characteristics to the central controller, and the central controller controls the feeding power mechanism, the cutter power mechanism and the cutting control motor to work according to the identified shrimp shape characteristics and the control parameters input by the interactive end, the cutter power mechanism is used to control the cutter structure to cut the shrimp body, and the cutting control motor is used to control the cutter to approach or move away from the shrimp feeding roller teeth, and when the shrimp contacts the shrimp blocking block 7, the shrimp is stopped by the shrimp blocking block 7, so that the shrimp falls off the shrimp feeding roller teeth 4;

[0061] The present invention mainly relies on the shrimp-feeding roller teeth 4 to penetrate into the shrimp's abdomen to achieve the positioning of the shrimp. Compared with the smooth and hard shrimp back, the shrimp's abdomen is rougher and softer due to the presence of shrimp legs. Therefore, the pressing force required for the shrimp-feeding roller teeth 4 to penetrate into the shrimp's abdomen is relatively small. The squeezing force of the shrimp-feeding roller teeth 4 and the shrimp-feeding pressure wheel without spikes on the shrimp is greatly reduced, reducing the damage to the shrimp and improving the quality of shrimp cutting. In addition, since the shrimp-feeding roller teeth 4 fit the shrimp's abdomen, the slippage of the shrimp's abdomen is hindered. Even if the shrimp's abdomen is slightly deflected, the shrimp-feeding pressure wheel can rely on its own smooth surface to effectively fit the shrimp's back to adaptively adjust the shrimp's posture and ensure the quality of shrimp cutting. The open shrimp outlet areas 6 on both sides of the radial direction of the cutter structure fully avoid the squeezing and blocking of the shrimp, that is, reduce the squeezing damage to the shrimp, so that the entire device can adaptively process shrimps of various sizes, effectively improving the efficiency of shrimp cutting. In summary, compared with the prior art, the present invention effectively solves the technical problems of poor shrimp cutting quality and low processing efficiency in the prior art of shrimp cutting equipment.

[0062] Second embodiment:

[0063] like Fig.11As shown, the cutting control mechanism is no longer a cutting control motor, but a push cylinder 26. Accordingly, a mounting hole 27 is provided on the mounting plate, and the mounting seat is guided and assembled in the mounting hole 27. The cutter on the mounting seat is controlled to approach or move away from the shrimp feed roller teeth by the linear motion of the push cylinder 26. Of course, when the mounting plate is provided with a mounting hole 27, in other embodiments, the push cylinder can also be an electromagnet or a motor. At this time, the output end of the motor is connected to a screw rod, and the mounting seat is fixed on the screw rod. The motor drives the screw rod to rotate to drive the mounting seat to move linearly in the mounting hole 27.

[0064] Third embodiment:

[0065] like Fig.12 As shown, the shrimp-feeding pressure wheel no longer relies on the rotation of the swing arm 13 to achieve fine-tuning swing, but a spring structure is provided, the spring structure includes a shell, a guide rod and a spring 28 sleeved on the guide rod are provided in the shell, the rotating shaft 11 of the shrimp-feeding pressure wheel extends into the shell and is sleeved on the guide rod, and the shrimp-feeding pressure wheel presses on the shrimp back under the pressure of the spring 28. In other embodiments, a magnet can also be provided at each end of the extension direction of the spring 28, and the two magnets have the same magnetic properties. According to the principle of like charges repel each other, the shrimp-feeding pressure wheel presses on the shrimp back through the repulsive force between the two magnets; of course, in other embodiments, the shrimp-feeding pressure wheel can be suspended on the mounting plate through a connecting rod, and the shrimp-feeding pressure wheel presses on the shrimp back under the action of gravity by configuring a counterweight block, and accordingly, the connecting rod is a telescopic rod to meet the movement of the shrimp-feeding pressure wheel.

[0066] It should be emphasized that the main function of the shrimp-feeding pressing wheel is to correct the posture of the shrimp and press the shrimp into the teeth (shrimp-feeding roller teeth 4). The shrimp-feeding pressing wheel can swing under the drive of the swing arm 13 to adapt to the change from the shrimp tail to the shrimp head and the change of different types of shrimp. The shrimp-feeding pressing wheel needs to have a certain pressing force. On this theoretical basis, the pressing force of the shrimp-feeding pressing wheel can come from a spring, its own gravity and magnetic force.

[0067] Fourth embodiment:

[0068] like Fig.13 As shown, the roller wheel is replaced by a roller tooth straight plate 29, and shrimp roller teeth are arranged on the roller tooth straight plate 29. The roller tooth straight plate 29 is no longer driven by the rotation of the motor, but is driven to reciprocate linearly by the roller tooth cylinder 30. Of course, in other embodiments, the roller tooth straight plate can also be driven by an electromagnet, a motor, etc. to make a linear motion.

[0069] In the present invention, unless otherwise clearly stipulated and limited, for example, it can be a fixed connection, a detachable connection, or an integrated one; it can be a mechanical connection or an electrical 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 the specific circumstances.

[0070] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
