Description

Technical Field

[0001] This invention relates to the field of blades, specifically to an antistatic plastic shredder blade. Background Technology

[0002] In the operation of a plastic shredder, the blades are a key component, and their performance directly affects the shredding effect and the service life of the equipment. Traditional plastic shredder blades have many problems: During the plastic crushing process, static electricity is easily generated due to friction between the plastic and the blades. The accumulation of static electricity not only attracts dust and impurities, affecting the purity of the crushed plastic, but may also ignite sparks under certain conditions, posing a safety hazard, especially when handling flammable and explosive plastic materials. Blades typically consist of a handle and a blade plate. Traditional connection methods may not be secure enough; under prolonged high-speed operation and frequent impacts with materials, the blade plate can easily loosen or even detach, leading to equipment malfunction, reduced production efficiency, and potential damage to other components. Blades need to be mounted on a blade mounting base. Traditional mounting structures may not adequately accommodate different installation requirements, and after installation, the lack of effective fixing and cushioning measures can cause bolts to loosen during equipment vibration, affecting the normal use of the blades. When the blades rotate at high speed to crush plastic, a large amount of frictional heat is generated between them and the material. If heat is not dissipated in time, the blade temperature will become too high, accelerating blade wear, reducing blade life, and potentially even melting the plastic, affecting the crushing effect. Summary of the Invention

[0003] The purpose of this invention is to provide an antistatic plastic shredder blade to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an antistatic plastic crusher blade, comprising an antistatic coated blade handle, an antistatic coated blade plate inserted into one end of the antistatic coated blade handle, an insert plate fixed to the surface of the antistatic coated blade plate, the insert plate being inserted into the interior of the antistatic coated blade handle, a screw fixed to one end of the insert plate, a screw rod passing through the antistatic coated blade handle and fitted with a screw nut, and a bolt elongated hole being formed on the surface of the antistatic coated blade handle, the bolt elongated hole passing through the antistatic coated blade handle and the insert plate.

[0005] Preferably, the surface of the antistatic coated knife handle is provided with a splicing groove, the surface of the antistatic coated knife plate is fixed with a splicing strip, the splicing strip is inserted into the splicing groove, and elastic traction members are provided between the two ends of the splicing strip and the antistatic coated knife handle.

[0006] Preferably, the elastic traction component includes an elastic hanger and a retaining strip. The elastic hanger is fixed to the end of the antistatic coated knife handle. The retaining strip is a right-angled trapezoidal strip and is fixed to one end of the elastic hanger. The retaining strip is inserted into a notch opened at the end of the splicing strip. The width of the notch is smaller than the width of the splicing strip. A pull ring is fixed to one end of the elastic hanger. The pull ring and the retaining strip are symmetrically distributed about the elastic hanger.

[0007] Preferably, the surface of the splicing groove is provided with multiple slots, and the slots and insert plates correspond one to one. The insert plates are inserted into the slots, and the surface of the slots is provided with through holes. The screw passes through the through holes and is fitted with a screw nut.

[0008] Preferably, a rubber pad is fixed to one side of the antistatic coated knife handle. The surface of the rubber pad has multiple through holes, and the through holes and perforations correspond one-to-one. The screw passes through the perforations.

[0009] Preferably, the surface of the insert plate is provided with a second elongated bolt hole, and after the insert plate is inserted into the slot, the first elongated bolt hole and the second elongated bolt hole are connected.

[0010] Preferably, the surface of the antistatic coated knife handle has multiple sets of heat dissipation holes, and each set of heat dissipation holes has multiple holes.

[0011] Preferably, a second rubber pad is fixed to both the top and bottom surfaces of the antistatic coated knife handle. The second rubber pad is annular, and the inner ring size of the second rubber pad is equal to the groove size of the long oval hole of the bolt.

[0012] Compared with the prior art, the beneficial effects of the present invention are: The antistatic plastic crusher blade proposed in this invention, by adopting an antistatic coating design on both the handle and the blade plate, can effectively prevent the accumulation of static electricity caused by friction during the crushing process of plastic, reduce the adsorption of dust and impurities, ensure the purity of the crushed plastic, and at the same time reduce the safety risk of sparks caused by static electricity, thereby improving the safety of the equipment when processing special plastic materials.

[0013] The insertion structure of the insert plate and slot, along with the fastening method of the screw and nut, makes the connection between the cutter handle and the cutter plate more stable. During the process of pushing the cutter plate to insert the splicing strip into the splicing slot, the screw passes through the through hole and the through hole of the rubber gasket, then the nut is screwed on and secured. The rubber gasket undergoes elastic deformation and rebounds to support the nut, further enhancing the connection strength between the screw and the nut. This effectively prevents the cutter plate from loosening or falling off during prolonged high-speed operation and frequent impacts with materials, improving the stability and production efficiency of the equipment.

[0014] An elastic traction element is installed between the splicing strip and the splicing groove. When the splicing strip is inserted into the splicing groove, the end of the splicing strip pushes against the inclined surface of the retaining strip, causing the elastic hanger to deform elastically. When the splicing strip is fully inserted, the elastic hanger rebounds and pushes the retaining strip into the notch, achieving pre-limiting positioning during the assembly of the blade holder and blade plate. This design makes the blade assembly more convenient and faster, reduces errors during the assembly process, and improves assembly efficiency and accuracy.

[0015] The second elongated bolt hole on the surface of the insert plate connects with the first elongated bolt hole on the surface of the tool holder after assembly, facilitating flexible installation according to the specifications of the tool mounting base. Simultaneously, the second rubber gasket fixed to the top and bottom surfaces of the tool holder is clamped, deformed, and springs back when the bolts are tightened, making the bolts even more secure and effectively preventing them from loosening during equipment vibration, thus ensuring the stable fixation of the blade on the tool mounting base.

[0016] Multiple sets of heat dissipation holes are provided on the surface of the blade handle, with each set containing multiple holes. This allows the heat generated by the blade during the crushing of plastic to be dissipated in a timely manner, reducing the blade temperature, slowing down the wear rate of the blade, extending the service life of the blade, and preventing the plastic from melting due to excessive temperature, thus ensuring the crushing effect.

[0019] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-7 This invention provides a technical solution: an antistatic plastic crusher blade, comprising an antistatic coated blade handle 1, an antistatic coated blade plate 2 inserted into one end of the antistatic coated blade handle 1, an insert plate 202 fixed to the surface of the antistatic coated blade plate 2, the insert plate 202 being inserted into the interior of the antistatic coated blade handle 1, a screw 4 fixed to one end of the insert plate 202, one end of the screw 4 penetrating the antistatic coated blade handle 1 and fitted with a screw nut 401, and a bolt elongated hole 103 formed on the surface of the antistatic coated blade handle 1. Hole 103 penetrates the antistatic coated knife handle 1 and the insert plate 202; the surface of the splicing groove 101 is provided with multiple slots 102, each corresponding to an insert plate 202, the insert plate 202 is inserted into the slot 102, the surface of the slot 102 is provided with through holes 105, the screw 4 passes through the through holes 105 and is fitted with a screw nut 401; a rubber gasket 3 is fixed on one side of the antistatic coated knife handle 1, the surface of the rubber gasket 3 is provided with multiple through holes, each corresponding to an through hole 105, the screw 4 passes through the through holes 105.

[0021] When assembling the antistatic coated knife handle 1 and the antistatic coated knife plate 2, first insert the insert plate 202 into the corresponding slot 102, push the antistatic coated knife plate 2 so that the splicing strip 201 is inserted into the splicing groove 101, and the screw 4 passes through the through hole 105 and the through hole on the surface of the rubber gasket 3. Then, the nut 401 is sleeved and screwed onto the screw 4. The rubber gasket 3 is clamped between the antistatic coated knife handle 1 and the nut 401 and produces elastic deformation. The rubber gasket 3 rebounds and supports the nut 401, so that the screw 4 and the nut 401 are screwed firmly.

[0022] To achieve pre-limiting positioning during the assembly of the antistatic coated tool holder 1 and the antistatic coated tool plate 2, the following was proposed: The surface of the antistatic coated knife handle 1 is provided with a splicing groove 101. The surface of the antistatic coated knife plate 2 is fixed with a splicing strip 201. The splicing strip 201 is inserted into the splicing groove 101. Elastic traction elements are provided between the two ends of the splicing strip 201 and the antistatic coated knife handle 1. The elastic traction elements include an elastic hanging piece 6 and a retaining strip 601. The elastic hanging piece 6 is fixed to the end of the antistatic coated knife handle 1. The retaining strip 601 is a right-angled trapezoidal strip. The retaining strip 601 is fixed to one end of the elastic hanging piece 6 and is inserted into a notch 204 opened at the end of the splicing strip 201. The width of the notch 204 is smaller than the width of the splicing strip 201. A pull ring 602 is fixed to one end of the elastic hanging piece 6. The pull ring 602 and the retaining strip 601 are symmetrically distributed about the elastic hanging piece 6.

[0023] When the splicing strip 201 is inserted into the splicing groove 101, the end of the splicing strip 201 pushes against the inclined surface of the retaining strip 601, causing the elastic hanging piece 6 to undergo elastic deformation. When the splicing strip 201 is fully inserted into the splicing groove 101, the elastic hanging piece 6 rebounds and pushes the retaining strip 601 into the notch 204. The elastic hanging piece 6, together with the retaining strip 601, pulls and limits the splicing strip 201 in the splicing groove 101.

[0024] To ensure that the antistatic coated tool holder 1 can be mounted on the tool mount, the following is proposed: The surface of the insert plate 202 is provided with a bolt elongated hole 203. After the insert plate 202 is inserted into the slot 102, the bolt elongated hole 103 and the bolt elongated hole 203 are connected. The surface of the antistatic coated tool handle 1 is provided with multiple sets of heat dissipation holes 104, and each set of heat dissipation holes 104 is provided with multiple holes. The top surface and the bottom surface of the antistatic coated tool handle 1 are both fixed with rubber pads 25. The rubber pads 25 are annular pieces, and the inner ring size of the rubber pads 25 is equal to the groove size of the bolt elongated hole 103.

[0025] After the antistatic coated blade plate 2 is assembled on the antistatic coated blade holder 1, the bolt elongated hole 203 and the bolt elongated hole 103 correspond to each other, so that the bolt passes through the bolt elongated hole 103 and the bolt elongated hole 203 and is fixed on the tool mounting seat. After the bolt is tightened, the clamping rubber gasket 25 deforms and the rubber gasket 25 rebounds, making the bolt more secure.

[0026] Instructions for using the antistatic plastic shredder blades: Align the splicing strip 201 on the antistatic coated blade plate 2 with the splicing groove 101 on the surface of the antistatic coated blade handle 1 and insert it. During insertion, the end of the splicing strip 201 will push against the inclined surface of the retaining strip 601 in the elastic traction component. Since the retaining strip 601 is a right-angled trapezoidal strip and fixed to one end of the elastic hanging piece 6, the elastic hanging piece 6 will undergo elastic deformation. When the splicing strip 201 is fully inserted into the splicing groove 101, the elastic hanging piece 6 rebounds, pushing the retaining strip 601 into the notch 204 opened at the end of the splicing strip 201. At the same time, the elastic hanging piece 6, in conjunction with the retaining strip 601, pulls and limits the splicing strip 201 in the splicing groove 101, achieving pre-limiting during assembly. If disassembly is required, pull the pull ring 602 fixed to one end of the elastic hanging piece 6 to disengage the retaining strip 601 from the notch 204. Insert the insert plate 202 on the surface of the antistatic coated blade 2 into the corresponding slot 102 on the surface of the antistatic coated blade handle 1. Push the antistatic coated blade 2 so that the splicing strip 201 is fully inserted into the splicing slot 101. At this time, the screw 4 passes through the through hole 105 on the surface of the slot 102 and the through hole on the surface of the rubber washer 3 fixed on one side of the antistatic coated blade handle 1. Then, screw the nut 401 onto the screw 4. The rubber washer 3 is clamped between the antistatic coated blade handle 1 and the nut 401 and undergoes elastic deformation. The rubber washer 3 rebounds and supports the nut 401, so that the screw 4 and the nut 401 are firmly screwed together, completing the assembly of the antistatic coated blade handle 1 and the antistatic coated blade 2. After assembly, the bolt elongated hole 203 on the surface of the insert plate 202 of the antistatic coated blade 2 is connected to the bolt elongated hole 103 on the surface of the antistatic coated blade handle 1. After passing the bolt through the first oblong hole 103 and the second oblong hole 203, it is fixed to the tool mounting base. During the bolt tightening process, the rubber gasket 25, which is fixed on both the top and bottom surfaces of the antistatic coated tool holder 1, deforms. The rubber gasket 25 rebounds, making the bolt even tighter and ensuring that the blade is stably installed on the tool mounting base. During the use of the blade, the multiple sets of heat dissipation holes 104 on the surface of the antistatic coated tool holder 1 can dissipate heat, ensuring that the temperature of the blade is within a reasonable range during use and extending the service life of the blade.
