[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

A flared discharge cover is provided at one end of the inner cylinder 4 provided with the discharge port 8. A driving member 10 (the driving member 10 adopts a belt driving member) connected to the fixed shaft 7 is installed in the equipment box 3. A sealing cover 11 is rotatably installed at one end of the fixed shaft 7 away from the inner cylinder 4. An electric cylinder 12 is installed on the outer side of the sealing cover 11, and the electric cylinder 12 is fixedly connected to the inner wall of the equipment box 3. The telescopic end of the electric cylinder 12 passes through the interior of the fixed shaft 7 and is installed with The sliding seat 13 is hollow inside, and the sliding seat 13 is slidably connected to the inner wall of the inner cylinder 4 (the outer wall of the sliding seat 13 is provided with a groove that cooperates with the copying plate 6), the free end of the electric cylinder 12 is inserted into the inner cavity of the sliding seat 13 (the sliding seat 13 and the electric cylinder 12 are relatively slidably connected) and a spike assembly 14 is rotatably installed, and the spike assembly 14 is slidably connected to the inner wall of the sliding seat 13, and a side of the sliding seat 13 away from the electric cylinder 12 is provided with a limiting hole 15 and a puncture hole 16 that cooperates with the spike assembly 14 A blocking hole assembly 17 that cooperates with the limiting hole 15 is rotatably installed on the inner side of the sliding seat 13, and one end of the blocking hole assembly 17 passes through the sliding seat 13, a limiting rod 18 that cooperates with the limiting hole 15 is installed on the spike assembly 14, and a top rod 19 that cooperates with the blocking hole assembly 17 is installed on the end cover 9. When the blocking hole assembly 17 abuts against the top rod 19, the blocking hole assembly 17 is separated from the limiting hole 15, so that the limiting rod 18 and the spike assembly 14 respectively pass through the limiting hole 15 and the puncture hole 16 to puncture the squid.

[0033] In this embodiment, the blocking hole assembly 17 includes a rotating sleeve 171 rotatably connected to the inner wall of the sliding seat 13, a stopper 172 that cooperates with the limiting hole 15 is fixedly connected to the outer wall of the rotating sleeve 171, a spiral groove 173 is opened on the inner wall of the rotating sleeve 171, a sliding rod 174 is slidably connected to the inner cavity of the rotating sleeve 171, and a limiting column 175 that cooperates with the spiral groove 173 is fixedly connected to the outer wall of the sliding rod 174. One end of the sliding rod 174 passes through the sliding seat 13 and is installed with a stopper 175 that cooperates with the top rod 19. The matching limit block 176 and the outer wall of the sliding rod 174 are provided with a spring 177, and the spring 177 is located between the limit block 176 and the sliding seat 13, wherein when the limit block abuts against the top rod, it can gradually push the sliding rod to slide, and the sliding rod can drive the rotating sleeve and the stopper to rotate through the cooperation of the limit column and the spiral groove, so that the stopper is separated from the covering of the limit hole, so that the limit rod can smoothly pass through the limit hole, that is, the extension of the electric cylinder can drive the spike of the spike assembly to pass through the sliding seat.

[0034] In this embodiment, in order to match the acid discharge of different numbers of squids, the top rod 19 also includes a screw 191 rotatably connected to the end cover 9. The top rod 19 is sleeved on the outer wall of the screw 191 and is threadedly connected to the screw 191. The top rod 19 and the end cover 9 are slidably connected. A limit strip 192 is provided on the outer wall of the top rod 19. The end cover 9 has a mounting hole that cooperates with the top rod 19 and the limit strip 192. The rotation of the screw can drive the top rod to slide, thereby realizing the extension and retraction of the top rod. When the top rod is extended, the top rod and the blocking hole assembly can abut against each other earlier, so that the distance between the sliding seat and the end cover becomes larger, thereby being able to accommodate more squids (that is, when there are more squids, the squids will not be excessively squeezed).

[0035] In this embodiment, the spike assembly 14 includes a mounting seat 141 rotatably connected to the telescopic end of the electric cylinder 12, a plurality of mounting strips 142 are fixedly connected to the outer wall of the mounting seat 141, and the mounting strips 142 are slidably connected to the inner wall of the sliding seat 13, the limiting rod 18 is installed on the mounting strip 142, and the mounting strip 142 is a fan-shaped mounting strip, a plurality of spikes 143 are installed on one side of the mounting strip 142 close to the puncture hole 16, and the spikes located on the periphery of the mounting strip are denser than the spikes on the inner periphery, wherein the setting of the mounting seat can enable relative rotation between the mounting strip and the electric cylinder, and the mounting strip is slidably connected to the inner wall of the sliding seat, so that the mounting strip and the spikes can rotate synchronously with the sliding seat, so that the spikes can pass through the puncture hole when the electric cylinder is extended.

[0036] In this embodiment, in order to adjust the length of the spike, a sliding ring 144 is slidably connected to the outer wall of the mounting seat 141, and a plurality of mounting strips 142 are installed on the outer wall of the sliding ring 144. A threaded groove 145 is provided on the outer wall of the mounting seat 141. Two sets of nuts 146 are threadedly connected to the outer wall of the mounting seat 141, and the two sets of nuts 146 are located on opposite sides of the sliding ring 144. The sliding seat 13 has a limiting hole 15 and a puncture hole 16 on one side thereof, which is a detachable structure. By rotating the two nuts, the position between the sliding ring and the mounting seat can be adjusted, thereby adjusting the relative position between the puncture and the electric cylinder.

[0037] In this embodiment, a drainage hole is provided on a side of the sliding seat 13 away from the limiting hole 15 and the puncture hole 16, so as to drain the water inside the sliding seat and avoid the water accumulating inside the sliding seat.

[0038] In this embodiment, in order to further improve the acid removal effect of the squid, an ultrasonic generator 20 is installed in the equipment box 3, and a transducer 21 that cooperates with the ultrasonic generator 20 is installed at the bottom of the inner cavity of the outer tube 2, so that when the squid is removing acid, the ultrasonic generator and the transducer can make the water in the outer tube vibrate, thereby realizing efficient acid removal of the squid.

[0039] In this embodiment, one end of the bottom of the outer cylinder 2 is connected to a drain pipe 22 , and a slope inclined toward the drain pipe 22 is provided at the bottom of the inner cavity of the outer cylinder 2 , and the top of the outer cylinder 2 is connected to a water inlet pipe 23 .

[0040] The specific working process of the above embodiment is as follows:

[0041] When the squid is processed, the squid is first cleaned and sliced, and then poured into the inner tube 4 and covered with the end cover 9.

[0042] Then, add the acid-draining liquid into the outer tube 2 through the water inlet pipe 23, and make sure that most of the acid-draining liquid covers the inner tube 4;

[0043] Then, the ultrasonic generator 20 and the driving motor of the driving member 10 are respectively started, wherein the ultrasonic generator 20, by cooperating with the transducer 21, makes the water in the outer cylinder 2 vibrate, and ultrasonically removes acid from the squid, while the driving member 10 drives the inner cylinder 4 to roll, so that the squid in the inner cylinder 4 is turned over, collided, and rolled under the action of the lifting plate 6, so that the myofibril structure of the squid is destroyed, so that the acid in the cells of the product is easier to flow out;

[0044] During the rolling and kneading process, the electric cylinder 12 is started regularly or irregularly, and the electric cylinder 12 pushes the sliding seat 13 to slide toward the end cover 9. During the sliding process, since the stopper 172 of the hole blocking assembly 17 covers the limiting hole 15, the limiting rod 18 abuts against the stopper 172, so that the electric cylinder 12 and the sliding seat 13 will not slide relative to each other, that is, the electric cylinder 12 will not drive the spike 143 to pass through the puncture hole 16;

[0045] During the sliding process of the sliding seat 13, since the inner cylinder 4 is provided with the water-through hole 5, the water in the inner cylinder 4 can be squeezed into the outer cylinder 2, and the sliding seat 13 can also push the squid in the inner cylinder 4 to the position of the end cover 9, and when the limit block 176 gradually contacts the top rod 19, the sliding rod 174 can be pushed to slide, and the mutual cooperation between the upper limit column 175 and the spiral groove 173 on the sliding rod 174 can drive the rotating sleeve 171 and the stopper 172 to rotate, so that the stopper 172 is separated from the coverage of the multi-limiting holes 15, and at this time, as the electric cylinder 12 continues to slide, the spike 143 can be pushed to pass through the puncture hole 16 and puncture the squid. After one puncture is completed, the electric cylinder 12 is retracted, the spike 143 is reinserted into the sliding seat 13, and the squid partially strung on the spike 143 is cleaned through the puncture hole 16 while the spike 143 slides back;

[0046] After the spike 143 is retracted into the sliding seat 13, the mounting seat 141 abuts against the inner side surface of the sliding seat 13, and then the sliding seat 13 is pulled back to slide, so that the limit block 176 is gradually separated from the top rod 19, and the limit block 176 and the sliding rod 174 return to their original positions under the action of the restoring force of the spring 177, so that the block 172 can cover the limit hole 15 again, and then the sliding seat 13 is pulled back to the initial position (it is also possible to extend the electric cylinder 12 again after the block 172 covers the limit hole 15 again, so that the puncture operation continues, and this process is repeated for multiple punctures). In the process of the sliding seat 13 sliding back, due to the continuous rotation of the inner cylinder 4 and the squid being re-immersed in the acid discharge liquid, the squid accumulated at the end cover 9 can gradually flow to the middle position.

[0047] After reciprocating rolling and puncturing, the drain pipe 22 is opened to drain the acid-discharging liquid, and then clean water is re-injected to clean the squid to remove the residual acid-discharging liquid. After cleaning and draining, the end cover 9 is opened, and then the electric cylinder 12 is started again to push the sliding seat 13 to slide, and the squid in the inner tube 4 is quickly pushed out to complete the acid-discharging operation of the squid. Since the limiting rod 18 and the top rod 19 will not contact each other, the spike 143 will not pass through the sliding seat 13.

[0048] When more squids are to be loaded into the inner tube 4, the screw rod 191 is first rotated to drive the push rod 19 to slide, and the length of the push rod 19 is adjusted. Then, the sliding seat 13 is slid to a position close to the discharge port 8 of the inner tube 4, and then the side of the sliding seat 13 on which the blocking hole assembly 17 is installed is removed (the two can be connected by bolts), and then the two nuts 146 are rotated in turn and the relative position between the sliding ring 144 and the mounting seat 141 is adjusted to adjust the penetration length of the spike 143, and then the sliding seat 13 is closed again to complete the adjustment.

[0049] In the present invention, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0050] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
