[0024] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] Please refer to Figures 1 to 4 As shown, the present invention provides an eel piercing machine, which includes a base 3, a conveying mechanism 2 and a piercing mechanism 1. The conveying mechanism 2 is provided on the base 3, and the piercing mechanism 1 is provided above the conveying mechanism 2. The piercing mechanism 1 is connected to the base 3.
[0026] The punching mechanism 1 includes a frame 101, a linear drive 102, a lifting frame 107, a slide bar 103, and a rolling punching assembly. The lower part of the frame 101 is fixedly connected to the middle part of the base 3. The lifting frame 107 is slidably connected to the upper part of the frame 101 through several slide bars 103. The linear drive 102 is connected to the upper part of the frame 101 and is linearly driven connected to the upper part of the lifting frame 107. The rolling punching assembly is provided at the lower part of the lifting frame 107, and a gap is provided between the rolling punching assembly and the conveying mechanism 2.
[0027] The working principle of this utility model is as follows: In actual production and use, when it is necessary to pierce the eel, the eel with its skin side facing up can be placed on the conveying mechanism 2. Then, the conveying mechanism 2 is operated, causing the conveying mechanism 2 to move the eel towards the piercing mechanism 1. When the eel passes through the rolling piercing assembly, the eel moves and is pierced under the cooperation of the rolling piercing assembly and the conveying mechanism 2. After the piercing is completed, the eel is output away from the piercing mechanism 1 through the conveying mechanism 2. When it is necessary to adjust the piercing depth of the eel, the linear drive 102 can be operated, so that the linear drive 102 adjusts the distance between the rolling piercing assembly and the conveying mechanism 2 through the lifting frame 107, thereby controlling the piercing depth of the rolling piercing assembly and the eel, and preventing the eel from being pierced too deeply or too insufficiently.
[0028] Furthermore, the rolling spike assembly includes a rotation drive 104, a roller 106, and several sets of spikes. The roller 106 is rotatably connected to the lower part of the lifting frame 107. The rotation drive 104 is drivenly connected to the roller 106. Several spikes are arranged from left to right on the outside of the roller 106.
[0029] The spiked portion includes a plurality of clusters of needles 105, which are arranged around the outside of the roller 106.
[0030] As can be seen from the above description, when it is necessary to puncture the eel, the rotating drive 104 can be operated, so that the rotating drive 104 drives several spikes to move through the roller 106, so that when the eel passes under the roller 106, the eel is punctured by the piercing needle 105.
[0031] Furthermore, it also includes an anti-stick plate 4, which is provided below the roller 106. The anti-stick plate 4 is connected to the frame 101. The anti-stick plate 4 is provided with a plurality of through grooves 5 that are adapted to the spikes. One spike is movably connected to one of the through grooves 5.
[0032] As can be seen from the above description, when the needle 105 is driven by the roller 106 to detach from the eel, in order to prevent the eel from moving along with the roller 106, the anti-stick plate 4 is used to block the eel, so that the eel can continue to be transported through the conveyor mechanism 2 after being pierced.
[0033] Furthermore, it also includes an anti-sticking component for spraying oil, which is disposed above the roller 106 and is connected to the frame 101;
[0034] The anti-sticking oil spraying assembly includes an oil pump 8, an oil inlet pipe 7, an oil outlet pipe 6, and several atomizing nozzles 9. The oil outlet pipe 6 is located above the roller 106 and is connected to the lifting frame 107. One side of the oil outlet pipe 6 is connected to the oil inlet pipe 7 through the oil pump 8, and several atomizing nozzles 9 are arranged on the other side of the oil outlet pipe 6.
[0035] As can be seen from the above description, when it is necessary to spray edible oil onto the needle 105, the oil pump 8 can be run to draw oil into the oil outlet pipe 6 through the oil inlet pipe 7, and then spray it onto the needle 105 on the roller 106 through the atomizing nozzle 9, which reduces the stickiness between the needle 105 and the eel meat, so that the meat of the eel can remain intact after being pricked.
[0036] Furthermore, it also includes a PLC controller, which is electrically connected to the conveying mechanism 2 and the punching mechanism 1 respectively.
[0037] As can be seen from the above description, it is beneficial to adjust the parameters of the eel punching machine through the PLC controller, and to make it more convenient for operators to operate the eel punching machine. Example 1
