Description

Technical Field

[0001] This utility model relates to the field of fishing net cutting technology, specifically a fishing net cutting knife assembly. Background Technology

[0002] As the name suggests, a fishing net is a net used for catching fish. In ancient times, people used coarse cloth and hemp as raw materials to make fishing nets by binding and rolling them. Although this type of fishing net was easily perishable and not very durable, its fishing efficiency was greatly improved. With the development of the fishing industry, the targets of fishing are no longer limited to fish, and the fishing tools have also evolved. More than 99% of fishing nets are made of synthetic fibers, and functionally they are divided into gillnets, dragging nets, purse seines, weaving nets, and drift nets.

[0003] A search revealed that Chinese patent CN218557193U discloses a fishing net positioning, cutting, and edge-collecting device. The device uses a material roller to unwind the fishing net, which then slides down a guide plate. When the net reaches the desired length, a lifting mechanism lowers the guide plate, causing a support rod to extend from a hole and insert into the net's mesh, lifting it up. Since the top of the support rod is aligned with the knot, a drive mechanism activates a cutting blade for high-temperature cutting, resulting in a clean cut and preventing the melted thread ends from detaching from the knot. After cutting, the net automatically detaches, and the lifting mechanism then... The guide plate rises as a whole, and the support rods no longer extend from the holes, which does not affect the fishing net from continuing to slide down the guide plate, achieving continuous and automated cutting. However, since the support rods extend from the holes and insert into the mesh of the fishing net to lift it up, and then cut at high temperature after the top of the support rods fits into the knot of the fishing net, the distance between the support rods is fixed. Different models of fishing nets have different mesh diameters, so it is impossible to ensure that each set of support rods fits into the knot. The unbalanced support leads to uneven support of the fishing net, resulting in an uneven cut and causing inconvenience to subsequent operations. To address this, we propose a fishing net cutting knife assembly. Utility Model Content

[0004] The purpose of this utility model is to provide a fishing net cutting knife assembly to solve the problem mentioned in the background art that, because the distance between the support rods is fixed and the mesh size of different fishing net models is different, it is impossible to ensure that each set of support rods is connected to the knot, resulting in uneven support and uneven net support, which in turn leads to uneven cutting and causes inconvenience to subsequent operations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fishing net cutting knife assembly, comprising: a platform, a cutting groove formed at the center of the top of the platform, support frames installed on the left and right sides of the platform, a track formed at the center of the inner side of the support frames, a first motor fixedly mounted on the top of the left support frame by bolts, a lead screw fixedly connected to the output end of the first motor, a limiting post passing through the inside of the right support frame, a first slider movably connected to the outer side of the lead screw, and a second slider movably connected to the outer side of the limiting post. A connecting block is fixedly connected to the side of the block and the second slider facing each other. A pressure block is fixedly connected to the inner side of the connecting block. The pressure block has three sets of cavities inside. Notches are opened on both sides and the bottom of the middle cavity. Heat-insulating silicone is fixed to the bottom of the pressure block. Heat dissipation holes are opened at the front and rear ends of the surface of the pressure block. Two sets of electric push rods are installed at the top of the pressure block. The bottom end of the electric push rods passes through the interior of the pressure block and is installed with a heat-conducting blade holder. A blade is fixed inside the heat-conducting blade holder by bolts. A heating device is fixedly connected to the center of the rear end of the pressure block by bolts.

[0006] Preferably, the position of the notch at the bottom matches the cutting groove, and the cavity is symmetrical about the central axis of the pressure block.

[0007] Preferably, the three sets of cavities are interconnected, and the cavities are connected to the outside world through the heat dissipation holes.

[0008] Preferably, the heat-conducting blade holder does not contact the pressure block, and the heat-conducting blade holder is connected to the heating device via a power cord.

[0009] Preferably, the electric actuator and the blade are linked through the heat-conducting blade holder.

[0010] Preferably, the first slider is threadedly connected to the lead screw, and the lead screw and the pressure block form a linkage structure through the first slider.

[0011] Preferably, the second slider is slidably connected to the limiting post.

[0012] Compared with the prior art, this utility model provides a fishing net cutting knife assembly with the following advantages: The fishing net cutting knife assembly installs the blade in the middle of the pressure block. The pressure block has a heat-insulating cavity inside and heat dissipation holes on the outside. Heat-insulating silicone is added to the contact surface with the fishing net to prevent deformation of the fishing net cutting line caused by excessive temperature of the pressure block. The pressure block flattens the two sides of the fishing net at the cutting position with the platform through a screw mechanism. The blade in the middle of the pressure block, after being heated, cuts the fishing net under the action of the electric push rod. This solves the problem of uneven edge cutting caused by uneven support during the cutting of the fishing net, and also has the effect of heat-melting edge wrapping. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1

[0025] like Figures 1 to 4As shown, a fishing net cutting knife assembly includes: a platform 1, with a cutting groove 12 at the center of the top of the platform 1; support frames 2 installed on the left and right sides of the platform 1; a track 25 at the center of the inner side of the support frame 2; a first motor 21 fixedly installed at the top of the left support frame 2 by bolts; a lead screw 22 fixedly connected to the output end of the first motor 21; a limiting post 221 passing through the inside of the right support frame 2; a first slider 23 movably connected to the outside of the lead screw 22; and a second slider 231 movably connected to the outside of the limiting post 221. A connecting block 24 is fixedly connected to one side of the block, and a pressure block 3 is fixedly connected to the inside of the connecting block 24. The pressure block 3 has three sets of cavities 31 inside, and notches 32 are opened on both sides and the bottom of the middle cavity 31. A heat-insulating silicone 33 is fixedly installed at the bottom of the pressure block 3. Heat dissipation holes 34 are opened at the front and rear ends of the surface of the pressure block 3. Two sets of electric push rods 4 are installed at the top of the pressure block 3. The bottom end of the electric push rod 4 is inserted into the interior of the pressure block 3 and a heat-conducting blade holder 41 is installed. A blade 42 is fixed inside the heat-conducting blade holder 41 by bolts. A heating device 43 is fixedly connected to the center of the rear end of the pressure block 3 by bolts.

[0026] In this implementation plan: the fishing net to be cut can be laid on the platform 1, and the cutting position is aligned with the cutting groove 12 for cutting. The support frame 2 supports the pressure block 3 and the heat-conducting blade holder 41. The screw 22 mechanism can adjust the height of the pressure block 3. The cavity 31 and heat-insulating silicone 33 inside the pressure block 3 play a heat insulation role to prevent the pressure block 3 from overheating and damaging the fishing net. The heat dissipation hole 34 plays a heat dissipation role. The electric push rod 4 can raise and lower the blade 42 to cut the fishing net. The heat-conducting blade holder 41 contains an electric heating wire inside. After being powered on, the blade 42 can be heated to perform heat-melting edge wrapping work on the edge of the fishing net.

[0027] like Figure 2 As shown, the bottom notch 32 is positioned to match the cutting groove 12, and the cavity 31 is symmetrical about the central axis of the pressure block 3.

[0028] In this implementation scheme: when the pressure block 3 is lowered to the lowest point, the bottom notch 32 is opposite to the cutting groove 12. When the blade 42 descends to cut, it extends into the interior of the cutting groove 12 to prevent the heated blade 42 from damaging the platform 1. The cavity 31 inside the pressure block 3 is designed symmetrically to dissipate heat evenly to the internal environment and prevent the temperature of the pressure block 3 from becoming too high.

[0029] like Figure 2 , Figure 4 As shown, the three cavities 31 are interconnected, and the cavities 31 are connected to the outside world through heat dissipation holes 34.

[0030] In this implementation scheme: the three sets of cavities 31 are interconnected, which can achieve the effect of ventilation and heat dissipation. The hollow design of the pressure block 3 can achieve the effect of heat insulation and prevent the temperature of the pressure block 3 from being too high. The heat dissipation holes 34 can dissipate the heat inside the pressure block 3.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, the heat-conducting knife holder 41 does not contact the pressure block 3, and the heat-conducting knife holder 41 is connected to the heating device 43 through a power cord.

[0032] In this embodiment: the heat-conducting blade holder 41 does not contact the pressure block 3, so as to avoid the pressure block 3 from contacting the heat-conducting blade holder 41 and heating up rapidly. The inner side of the heat-conducting blade holder 41 contains a heating wire, which is connected to the heating device 43 through a power cord to play a heating role.

[0033] like Figures 1 to 4 As shown, the electric actuator 4 forms a linkage structure with the blade 42 through the heat-conducting blade holder 41.

[0034] In this implementation plan: the electric push rod 4 is activated, and the electric push rod 4 extends downward to drive the heat-conducting blade holder 41 downward, which in turn drives the blade 42 to move downward to complete the cutting work.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, the first slider 23 is threadedly connected to the lead screw 22, and the lead screw 22 forms a linkage structure with the pressure block 3 through the first slider 23.

[0036] In this implementation scheme: the first motor 21 is started to rotate the lead screw 22, which drives the first slider 23 to move up and down, and drives the pressure block 3 to slide up and down through the connecting block 24, so as to lift and press the pressure block 3 to ensure the flatness of the cutting line.

[0037] like Figure 1 , Figure 3 As shown, the second slider 231 is slidably connected to the limiting post 221.

[0038] In this implementation scheme: the second slider 231 is a driven slider, which moves synchronously on the limit post 221 as the pressure block 3 is raised and lowered, thus balancing the pressure block 3.

[0039] Working principle: When using this fishing net cutting knife assembly, the worker first lays the fishing net to be cut on platform 1, aligns the cutting position with the cutting groove 12, and controls the heating device 43 via the PLC controller to start heating the blade 42 through the heat-conducting blade holder 41. When a certain temperature is reached, the PLC controller then turns on the first motor 21 and the electric push rod 4 to start the cutting work. The first motor 21 rotates the lead screw 22, which drives the first slider 23 to move up and down, and drives the pressure block 3 to slide up and down through the connecting block 24, thus pressing down the pressure block 3. When the pressure block 3 reaches its lowest point, the bottom notch 32 is aligned with the cutting groove 12, and the pressure block 3 cuts the fishing net. The net is pressed tightly onto platform 1 to prevent unevenness at the cut and to avoid uneven cutting edges. The electric actuator 4 drives the heat-conducting blade holder 41 downward, which in turn drives the blade 42 downward to complete the cutting of the fishing net and the heat-melting edge binding. When the blade 42 descends to cut, it extends into the inside of the cutting groove 12 to prevent the heated blade 42 from damaging platform 1. The hollow design of the pressure block 3 has a heat insulation effect to prevent the temperature of the pressure block 3 from being too high and damaging the fishing net. The heat dissipation hole 34 can dissipate the heat inside the pressure block 3. The model of the first motor mentioned above is: ZMYB-380, and the model of the electric actuator is: MNTL. The above first motor model is only for reference and can be used as long as it meets the working requirements.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
