Description

Technical Field

[0001] The invention relates to the technical field of glue spreading machines, and in particular to a fully automatic jaw plate glue spreading machine. Background Art

[0002] The tooth plate of jaw crusher is called jaw plate for short. It is a kind of mechanical equipment used to squeeze stones. The main component of jaw crusher is jaw plate, which is divided into fixed jaw plate and movable jaw plate. When the jaw crusher is in operation, the movable jaw is attached to the movable jaw plate to make compound pendulum motion, forming an angle with the fixed jaw plate to squeeze stones. Therefore, the jaw plate is a relatively easy-to-damage accessory in jaw crusher.

[0003] The jaw plate needs to be coated with glue on its surface during the manufacturing process. The traditional operation is to apply glue manually. However, this method is not only slow in application speed and low in efficiency, which increases the labor burden of the staff, but also difficult to effectively ensure the application quality. In order to solve this problem, the prior art mostly adopts fully automatic glue spreading machines to apply glue to the surface of the jaw plate. However, the glue spreading machines in the prior art mostly simply apply glue to the surface of the jaw plate, lacking corresponding operations to make the glue more tightly adhere to the surface of the base plate, thereby making it difficult for subsequent attachments to better adhere to the surface of the jaw plate. Summary of the invention

[0004] The purpose of the present invention is to solve the above-mentioned shortcomings in the prior art and to propose a fully automatic jaw plate glue spreading machine.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A fully automatic jaw plate glue spreading machine, comprising a mounting frame and a bottom plate, wherein a conveying device is installed inside the mounting frame, and the conveying device is driven by a first motor fixedly mounted on the side wall of the mounting frame, and the bottom plate is placed on the upper surface of the conveying device at equal intervals, and further comprises: A mounting frame, the mounting frame is fixedly mounted at the middle position of the mounting frame, and an electric control device is fixedly mounted on the upper surface of the mounting frame; A fixed shaft, the fixed shaft is rotatably installed between the inner walls on both sides of the mounting frame, the fixed shaft is driven by a second motor fixedly installed on the mounting frame, a rotating roller is fixedly connected to the middle position of the fixed shaft, the rotating roller is made of elastic metal, a liquid storage tank is fixedly installed inside the rotating roller, glue is stored inside the liquid storage tank, a plurality of liquid infusion tubes connected to the inside of the liquid storage tank are evenly distributed on the outer surface of the liquid storage tank, one end of the liquid infusion tube away from the liquid storage tank is connected to a rubber plate after passing through the side wall of the rotating roller, and a plurality of liquid storage tanks are evenly spaced inside the rubber plate, and the plurality of liquid storage tanks are all connected to the liquid infusion tube; A plurality of supporting protrusions are evenly distributed on the outer surface of the rotating roller, and the supporting protrusions are located at the gap between two circumferentially adjacent rubber plates, and the length of the supporting protrusions is greater than the thickness of the rubber plate.

[0006] Preferably, a plurality of blowing pipes are fixedly installed at equal intervals on the upper front side of the mounting frame, and the working ends of the plurality of blowing pipes face downwards.

[0007] Preferably, a corona device is fixedly mounted on the front side of the inner top wall of the mounting frame.

[0008] Preferably, a surrounding permanent magnet is fixedly mounted on the lower end of the corona device, and a plurality of spiral electrodes are fixedly mounted at equal intervals on the inner side of the surrounding permanent magnet.

[0009] Preferably, an electric slide groove is opened on the rear side of the top wall of the mounting frame, and two symmetrically arranged electric sliders are slidably installed inside the electric slide groove. Connecting rods are fixedly installed on the two electric sliders, and an insulating plate is fixedly installed on the lower end of the connecting rod.

[0010] Preferably, electrode plates are fixedly mounted on ends of the two insulating plates that are away from each other.

[0011] Preferably, the liquid storage tank is designed to be concave and have a smaller outlet.

[0012] Preferably, an electromagnetic plate is slidably mounted on an outer side of a section of the liquid infusion tube between the liquid storage tank and the rotating roller, a spring is fixedly mounted on the outer surface of the electromagnetic plate, and one end of the spring away from the electromagnetic plate is connected to the inner wall of the rotating roller.

[0013] Preferably, the rubber plate and the electromagnetic plate are both arranged in an arc shape.

[0014] Preferably, the electromagnetic plate is supplied with alternating current by external power supply equipment.

[0015] Compared with the prior art, the advantages of the present invention are: 1. In the present application, by setting up an air blower, when the bottom plate moves to the front side of the mounting frame, the air blower will blow air to the surface of the bottom plate to clean the dust on the surface of the bottom plate.

[0016] 2.

The present application forms a higher electric field strength around the electrode by setting up surrounding permanent magnets and spiral electrodes, which is beneficial to improving the efficiency and intensity of corona discharge, so that the surface of the treated material can be more fully exposed to the action of plasma, thereby better improving the surface properties. At the same time, the surrounding permanent magnets surrounding the discharge area can produce a relatively closed magnetic field environment. This magnetic field can constrain the plasma and make it more concentrated in the discharge area. The constraining effect of the magnetic field can reduce the diffusion of plasma into the surrounding space, increase the density and energy of the plasma, and thus improve the effect of corona.

At the same time, the magnetic rotating roller on the electromagnetic plate can make the glue better adhere to the surface of the metal plate under the action of the magnetic field, especially for some tiny unevenness or pores, magnetism can help the glue to fill better, thereby increasing the contact area and adhesion between the glue and the base plate, making the subsequent bonding more firm.

[0019] In summary, the present application can make the glue adhere to the surface of the base plate more fully through the design of the above-mentioned structure, and increase the contact area and adhesion between the glue and the base plate, making the subsequent bonding more firm.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figures 1 to 7 A fully automatic jaw plate glue spreading machine includes a mounting frame and a base plate 8. A conveying device 1 is installed inside the mounting frame. The conveying device 1 is a prior art, and its specific structural design is not repeated here. The conveying device 1 is driven by a first motor 2 fixedly installed on the side wall of the mounting frame. The base plates 8 are placed on the upper surface of the conveying device 1 at equal intervals, and the base plates 8 are transported by the conveying device 1.

[0030] A mounting frame 3 is fixedly installed in the middle position of the mounting frame, and an electric control device 6 is fixedly installed on the upper surface of the mounting frame 3. The electric control device 6 is a prior art and is used to control the operation of the entire device. A plurality of blowing pipes 7 are fixedly installed at equal intervals on the front side above the mounting frame 3. The working ends of the plurality of blowing pipes 7 face downward. When the base plate 8 moves to the front side of the mounting frame 3, the blowing pipes 7 will blow air to the surface of the base plate 8 to clean the dust on the surface of the base plate 8.

[0031] A corona device 21 is fixedly installed on the front side of the inner top wall of the mounting frame 3, a surrounding permanent magnet 22 is fixedly installed on the lower end of the corona device 21, and a plurality of spiral electrodes 23 are fixedly installed at equal intervals on the inner side of the surrounding permanent magnet 22. By setting the corona device 21, the surface of the base plate 8 can be corona treated to increase the roughness and surface energy of the surface of the base plate 8, so that the subsequent glue coating layer can be more firmly attached to the surface of the base plate 8, and at the same time, the wear resistance and corrosion resistance of the surface of the base plate 8 can be improved.

[0032] An electric slide 4 is provided on the rear side of the top wall of the mounting frame 3, and two symmetrically arranged electric sliders are slidably installed inside the electric slide 4. Connecting rods 9 are fixedly installed on the two electric sliders, and insulating plates 10 are fixedly installed on the lower ends of the connecting rods 9. Electrode plates 11 are fixedly installed on the ends of the two insulating plates 10 that are away from each other, so that when the electric slide 4 and the electric slider are running, the two connecting rods 9 can respectively drive the insulating plates 10 to move closer to or away from each other, thereby facilitating clamping them from the side of the bottom plate 8.

[0033] A fixed shaft 12 rotatably installed between the inner walls on both sides of the mounting frame 3 is arranged between the corona device 21 and the two groups of connecting rods 9. The fixed shaft 12 is driven by a second motor 5 fixedly installed on the mounting frame 3. A rotating roller 13 is fixedly connected to the middle position of the fixed shaft 12. The rotating roller 13 is made of elastic metal. A liquid storage tank 17 is fixedly installed inside the rotating roller 13. Glue is stored in the liquid storage tank 17. A plurality of liquid infusion tubes 18 connected to the interior of the liquid storage tank 17 are evenly distributed on the outer surface of the liquid storage tank 17. The end of the liquid infusion tube 18 away from the liquid storage tank 17 is connected to a rubber plate 14 after passing through the side wall of the rotating roller 13. The rubber plate 14 is arranged in an arc shape, and a plurality of liquid storage tanks 15 are evenly spaced inside the rubber plate 14. The plurality of liquid storage tanks 15 are all connected to the liquid infusion tube 18.

[0034] An electromagnetic plate 20 is slidably mounted on the outer side of the liquid replenishing tube 18 between the liquid storage tank 17 and the rotating roller 13. The electromagnetic plate 20 is arranged in an arc shape and a spring 19 is fixedly mounted on its outer surface. The end of the spring 19 away from the electromagnetic plate 20 is connected to the inner wall of the rotating roller 13. The electromagnetic plate 20 is supplied with alternating current by an external power supply device, which will generate an induced electromotive force in the liquid storage tank 17. According to Faraday's law of electromagnetic induction, an induced current is generated, which slightly increases the temperature of the glue inside the liquid storage tank 17, improves the fluidity and improves the adhesion strength.

[0035] A plurality of support protrusions 16 are evenly distributed on the outer surface of the rotating roller 13 . The support protrusions 16 are located at the gap between two circumferentially adjacent rubber plates 14 . The length of the support protrusions 16 is slightly greater than the thickness of the rubber plates 14 .

[0036] The specific working principle of the present invention is as follows: the first motor 2 drives the conveying device 1, the base plate 8 starts to move on the conveying device 1, the second motor 5 drives the rotating roller 13 to rotate, and according to the width of the base plate 8, the connecting rod 9 is controlled to move in the electric slide 4, so that the spacing between the two insulating plates 10 matches the width of the base plate 8. When the base plate 8 moves to the front side of the mounting frame 3, the blowing pipe 7 will blow air to blow on the surface of the base plate 8 to clean the dust on the surface of the base plate 8.

[0037] Then the corona device 21 is started, and a surrounding permanent magnet 22 is arranged around the spiral electrode 23. Such a design has the following advantages.

[0038] First, corona treatment is performed on the surface of the bottom plate 8 to increase the roughness and surface energy of the bottom plate 8 surface, so that the subsequent glue coating layer can be more firmly attached to the surface of the bottom plate 8, and at the same time, the wear resistance and corrosion resistance of the surface of the bottom plate 8 can be improved; Second: The spiral electrode 23 can generate a stronger electric field than an ordinary straight electrode at the same input voltage. This is because the spiral structure increases the effective length of the electrode and makes the charge distribution more concentrated, thereby forming a higher electric field strength around the electrode, which is conducive to improving the efficiency and intensity of corona discharge, so that the surface of the treated material can be more fully exposed to the action of plasma, thereby better improving the surface properties; Third: The surrounding permanent magnets 22 surrounding the discharge area can produce a relatively closed magnetic field environment. This magnetic field can constrain the plasma and make it more concentrated in the discharge area. The confinement effect of the magnetic field can reduce the diffusion of plasma into the surrounding space, increase the density and energy of the plasma, and thus improve the corona effect.

[0039] After the corona treatment, the bottom plate 8 enters under the rotating roller 13, and the rubber sheet 14 on the surface of the rotating roller 13 is distributed at equal intervals according to the position of the adhesive magnetic block on the bottom plate 8, ensuring that when glue is applied to the bottom plate 8, it will only be applied to the installation position, which can not only avoid waste, but also avoid applying glue to excess parts of the bottom plate 8, which will cause dust and impurities to stick to it.

[0040] The support protrusion 16 first slightly lifts the slightly deformable rotating roller 13 (made of elastic metal) in the area where glue is not applied. When it moves to the area where glue needs to be applied, the rotating roller 13 has an inertia to return to its original state downward. The middle electromagnetic plate 20 also presses the spring 19 downward under the action of inertia. The liquid storage tank 15 on the surface of the rubber plate 14 is a concave design with a small outlet. The glue in the liquid storage tank 15 is replenished by the internal liquid storage tank 17 through the liquid replenishing tube 18. Alternating current is passed into the electromagnetic plate 20. This design has the following advantages.

[0041] First: When the electromagnetic plate 20 surrounds the metal liquid storage tank 17 and an alternating current is passed through it, an induced electromotive force is generated in the liquid storage tank 17, and an induced current is generated according to Faraday's law of electromagnetic induction, which slightly increases the temperature of the glue inside the liquid storage tank 17, improves fluidity and increases adhesion strength; Second: Under the action of inertia, the electromagnetic plate 20 and the rubber plate 14 have a tendency to press downward. The design of the liquid storage tank 15 being concave and having a small outlet means that the liquid cannot flow out at first under the surface tension of the liquid. When the liquid contacts the surface of the bottom plate 8 under the action of inertia, the glue can be squeezed out and evenly applied on the bottom plate 8. Third: the surface energy of the bottom plate 8 after corona treatment is increased. The rotating roller 13 with magnetism through the electromagnetic plate 20 can make the glue adhere to the surface of the metal plate better under the action of the magnetic field, especially for some tiny unevenness or pores. Magnetism can help the glue fill better, thereby increasing the contact area and adhesion between the glue and the bottom plate 8, making the subsequent bonding more firm.

[0042] After applying glue on the bottom plate 8, the two sides of the bottom plate 8 are in contact with the insulating plate 10, which not only plays a positioning role, but also can scrape off the glue that may penetrate into the two sides of the bottom plate 8. At the same time, the electrode plate 11 is energized to form a discharge channel between the two plates, forming a dielectric barrier discharge. In the dielectric barrier discharge environment, taking epoxy glue as an example, the active substances generated by the discharge may react with the epoxy groups. The bottom plate 8 after glue coating is in a weaker dielectric barrier discharge environment (the discharge channel width is larger), and the glue solidification time will be slightly extended, which is convenient for the subsequent adhesion of the magnetic blocks.

[0043] After the bottom plate 8 comes out from under the mounting frame 3, the surface can be smeared with glue in the area where the magnetic blocks are bonded, which is very convenient.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
