Description

Technical Field

[0001] The utility model relates to the technical field of anvil production, and more particularly to a film winding and packaging device for a hard alloy anvil. Background Art

[0002] In the production process of cemented carbide anvils, the anvil blank after molding needs to be cold isostatically pressed. When the product is cold isostatically pressed, it needs to be protected to prevent the liquid in the cold isostatic press from infiltrating the product. At present, a film wrapping packaging device is generally used to wrap a film around the surface of the anvil to prevent liquid from entering.

[0003] For example, the existing relevant patent: CN113879586B is retrieved, which discloses a carbide top hammer film wrapping packaging device. The existing technology controls the lifting cylinder to rise so that it drives the lifting plate to rise to lift the top hammer workpiece and separate it from the packaging platform, and then drives the lifting plate to rotate 45° clockwise or counterclockwise around its axis through the dividing plate, thereby driving the top hammer workpiece to rotate 45° around its axis, thereby driving the top hammer workpiece to rotate 45° around its axis, thereby conveniently and comprehensively packaging the surface of the top hammer workpiece without any packaging dead angles.

[0004] However, the inventors found that the existing technology had the following problems when in use: in the existing technology, when the top hammer is reversed, the lifting plate is driven by the lifting cylinder to lift the top hammer away from the packaging platform, and then the entire lifting cylinder and the top hammer are reversed. However, since the lifting plate in the existing technology lacks a structure to restrict the top hammer, the top hammer may shake or even fall during the reversal process of the top hammer, which affects the stability of the top hammer during reversal and reduces the effect of wrapping the film around the surface of the top hammer. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the purpose of the utility model is to provide a carbide top hammer film wrapping packaging device that can clamp the top hammer when the disc lifts the top hammer and separates it from the top plate, thereby preventing the risk of the top hammer being offset or even falling during the rotation of the top hammer driven by the disc, and ensuring the stability of the top hammer during the reversing process.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] The top plate is provided with a circle, and the bottom plate is provided with a circle, and the top plate is provided with the bottom plate, and the bottom plate is provided with a circle.

[0008] The utility model is further configured as follows: a dividing plate is provided on the bottom plate, a lifting cylinder for controlling the vertical displacement of the disc is provided on the upper end of the output shaft of the dividing plate, and the upper end of the telescopic rod of the lifting cylinder is connected to the lower surface of the disc.

[0009] The utility model is further configured as follows: two extension plates are provided on the outer surfaces of the opposite sides of the disc, the disc and the two extension plates are all located directly below the clearance groove, and can both extend out of the clearance groove to contact the bottom of the top hammer.

[0010] The utility model is further configured as follows: the control component includes a transverse rotating shaft, both ends of which are rotatably connected to the front and rear inner walls of the disc respectively, and a fixed sleeve on the outer surface of the transverse rotating shaft is provided with a worm engaged with the worm gear.

[0011] The utility model is further configured as follows: a gear is fixedly sleeved on the outer surface of the horizontal rotating shaft, a rack is meshed and connected to the side of the gear, a control rod is provided on the lower surface of the rack, the lower end of the control rod slides through the lower surface of the disc, and a spring is movably sleeved on the outer surface of the control rod between the rack and the bottom wall of the disc.

[0012] The utility model is further configured as follows: a limit plate is provided on the side surface of the lifting cylinder housing close to the control rod, and a contact plate is provided at the lower end of the control rod. The contact plate is located directly below the limit plate and can contact the limit plate during the rising process.

[0023] See also Figure 1-4 , the utility model provides the following technical solutions:

[0024] Specifically, it refers to a carbide top hammer film wrapping packaging device, including four legs 1 and a top plate 3 arranged on the four legs 1, a bottom plate 2 is arranged between the four legs 1, the bottom plate 2 is located directly below the top plate 3, and a M-shaped giveway 4 is provided on the top plate 3 and extends from the lower surface of the top plate 3. A winding component 5 for wrapping a film around the surface of the top hammer is provided on the top plate 3. The winding component 5 is a disclosed technology in the existing patent: CN113879586B, and will not be described in detail here. At the same time, the width of the giveway 4 is smaller than the minimum width of the top hammer, so that the problem of the top hammer falling or tilting from the giveway 4 after being placed on the top plate 3 will not occur.

[0025] A dividing plate 7 is provided on the base plate 2, and a lifting cylinder 6 is provided on the upper end of the output shaft of the dividing plate 7. A disc 8 is provided on the upper end of the telescopic rod of the lifting cylinder 6. Two extension plates 9 are provided on the outer surfaces of the opposite sides of the disc 8. The disc 8 and the two extension plates 9 are all directly below the makeshift groove 4 and can both extend out of the makeshift groove 4 to contact the bottom of the top hammer. When one side of the top hammer is wound, the lifting cylinder 6 is started, and the telescopic rod of the lifting cylinder 6 pushes the disc 8 and the two extension plates 9 to move out of the makeshift groove 4 and contact the bottom of the top hammer. At the same time, the telescopic rod of the lifting cylinder 6 continues to push the disc 8 to move upward, thereby causing the top hammer to separate from the top plate 3. At this time, the dividing plate 7 drives the lifting cylinder 6 to rotate forty-five degrees clockwise or counterclockwise, thereby achieving the purpose of reversing the top hammer.

[0026] The outer surface of the disc 8 is provided with a clamping assembly 10, which includes two movable plates 101. The two movable plates 101 are mirror-imaged with the disc 8 as the center and are arranged on the outer surface of the disc 8. There is a ninety-degree angle between the movable plate 101 and the extension plate 9. Two arc-shaped clamping plates 102 for clamping the top hammer are provided on the opposite sides of the two movable plates 101. Therefore, the top hammer can be clamped by displacing the two arc-shaped clamping plates 102 in relative directions. The interior of the disc 8 is hollow. The widths of the movable plate 101 and the arc-shaped clamping plates 102 are both smaller than the width of the give way slot 4. Therefore, the movable plate 101 and the arc-shaped clamping plates 102 can pass through the give way slot 4. The adjacent sides of the two movable plates 101 slide through the disc 8. A vertical rotating shaft 103 is rotatably connected between the upper and lower inner walls of the center of the disc 8. The outer surface of the vertical rotating shaft 103 is sleeved with a worm gear 104. The worm gear 104 is close to the movable plate 8. A connecting shaft 105 is provided on the lower surface of one side of the plate 101, and the connecting shaft 105 is provided at the eccentric position of the worm gear 104. A connecting shaft 105 is also provided on the upper surface of one side of the movable plate 101 located in the disc 8. A control rotating plate 106 is provided for rotation between the two connecting shafts 105. A control component 11 for controlling the rotation of the worm gear 104 is provided in the disc 8. When the disc 8 lifts the top hammer and disengages from the top plate 3, the control component 11 controls the rotation of the worm gear 104, so that the worm gear 104 drives the connecting shaft 105 at its bottom to move in an eccentric direction. Therefore, the control rotating plate 106 can form a pulling force on the movable plate 101, so that the movable plate 101 is displaced into the disc 8, causing the two arc-shaped clamping plates 102 to move in relative directions, so that the top hammer can be clamped, preventing the risk of the top hammer being offset or even falling during the rotation of the top hammer driven by the disc 8, thereby ensuring the stability of the top hammer during the reversing process.

[0027] The control component 11 includes a transverse rotating shaft 1102, the two ends of which are rotatably connected to the front and rear inner walls of the disc 8 respectively. The outer surface of the transverse rotating shaft 1102 is provided with a worm 1103 that engages with the worm wheel 104. Therefore, when the transverse rotating shaft 1102 rotates, the worm 1103 rotates synchronously with the transverse rotating shaft 1102, so that the worm 1103 can engage the worm wheel 104 to rotate, thereby achieving the purpose of driving the worm wheel 104 to rotate.

[0028] When the gear 1105 is in the ascending position, the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear 1105 is in the ascending position, and the gear When the disc 8 is moved, the control rod 1101 and the contact plate 1107 will move upward synchronously with the disc 8. When the disc 8 contacts the bottom of the top hammer, the contact plate 1107 contacts the limit plate 1108. Since the telescopic rod of the lifting cylinder 6 continues to push the top hammer to move upward and disengage from the top plate 3, the limit plate 1108 can limit the contact plate 1107, making it impossible for the control rod 1101 to move upward. At this time, the rack 1105 is also unable to move, and the spring 1106 is stressed and contracts, so the gear 1104 is displaced on the surface of the rack 1105, so that the gear 1104 rotates under the drive of the teeth of the rack 1105, and the horizontal shaft 1102 rotates synchronously, thereby achieving the purpose of controlling the rotation of the worm gear 104. The above structure can automatically control the two arc-shaped clamping plates 102 to clamp the top hammer after the disc 8 contacts the top hammer, without the need for manual control, so that the clamping assembly 10 has a certain automation effect.

[0029] The working principle of the carbide top hammer film wrapping packaging device provided by the present invention is as follows: when one side of the top hammer is wrapped, the lifting cylinder 6 is started, and the telescopic rod of the lifting cylinder 6 pushes the disc 8 and the two extension plates 9 to move out of the clearance groove 4 and contact with the bottom of the top hammer. At this time, the contact plate 1107 is in contact with the limit plate 1108. Since the telescopic rod of the lifting cylinder 6 continues to push the top hammer to move upward and break away from the top plate 3, the limit plate 1108 can limit the contact plate 1107, so that the control rod 1101 cannot move upward. At this time, the rack 1105 cannot move either, and the spring 1106 is stressed and Contraction, so the gear 1104 is displaced on the surface of the rack 1105, so that the gear 1104 rotates under the drive of the teeth of the rack 1105, and the horizontal shaft 1102 rotates synchronously, and the worm 1103 can engage the drive worm wheel 104 to rotate, and the worm wheel 104 drives the connecting shaft 105 at its bottom to move in the eccentric direction, so the control rotating plate 106 can form a pulling force on the movable plate 101, so that the movable plate 101 is displaced into the disc 8, causing the two arc-shaped splints 102 to move in relative directions. When the disc 8 lifts the top hammer and disengages it from the top plate 3, the two arc-shaped splints 102 clamp the top hammer.
