Description

Technical Field

[0001] This invention relates to a feeding device, and more particularly to a feeding device for PVC sheet production. Background Technology

[0002] PVC sheets are smooth, flat, and crack-free sheets that can be customized in color. They also possess stable chemical properties and reliable insulation, making them widely used in construction, chemical, and other fields. The production of PVC sheets involves feeding raw materials into PVC sheet production equipment. Currently, workers manually move the raw materials to the equipment, open the bags containing the materials, and pour them into the equipment. During this pouring process, workers need to shake the bags to remove any remaining material. The materials are generally quite heavy, which can be tiring for workers.

[0003] To address the existing problems, a feeding device that can automatically dispense raw materials will be designed, making the feeding process easier for workers. Summary of the Invention

[0028] First implementation method

[0029] A feeding device for PVC sheet production, such as Figures 1-5 As shown, it includes a filling box 1, a support frame 2, a conveying mechanism 3, a moving mechanism 4, a clamping mechanism 5, and a blade 45. The top of the support frame 2 is bolted to the filling box 1. The filling box 1 is equipped with a conveying mechanism 3, which can convey raw materials. The filling box 1 is equipped with a moving mechanism 4, which can move the raw materials to the top of the filling box 1. The moving mechanism 4 is equipped with a clamping mechanism 5, which can clamp the bag containing the raw materials. The blade 45 is connected to the left side of the filling box 1. After the raw materials move to the top of the filling box 1, the blade 45 can cut the bag containing the raw materials, so that the raw materials are automatically poured into the filling box 1.

[0030] like Figure 1 and Figure 2 As shown, the conveying mechanism 3 includes a fixed frame 31, a first motor 32, a first gearbox 33, a first lead screw 34, and a bracket 35. The fixed frame 31 is bolted to the left side of the support frame 2. The first motor 32 is bolted to the lower right side of the fixed frame 31. The first gearbox 33 is bolted to the bottom of the fixed frame 31. The first gearbox 33 has one input end and two output ends. The input end of the first gearbox 33 is connected to the output shaft of the first motor 32. The first lead screw 34 is connected to both output ends of the first gearbox 33. The first lead screw 34 is used to convey raw materials. The first lead screw 34 is rotatably connected to the fixed frame 31. The bracket 35 is threaded between the first lead screws 34 and is used to place raw materials.

[0031] like Figure 1 , Figure 3 and Figure 5As shown, the moving mechanism 4 includes a guide rail 41, a second motor 42, a second lead screw 43, and a slide bar 44. The top of the loading box 1 is connected to the guide rail 41 by bolts. The second motor 42 is installed on the bottom left side of the guide rail 41 by bolts. The output shaft of the second motor 42 is connected to the second lead screw 43 by a coupling. The second lead screw 43 and the guide rail 41 are rotatably connected. The slide bar 44 is threaded on the second lead screw 43.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, the clamping mechanism 5 includes guide blocks 51, rollers 52, mounting plates 53, a third motor 54, a second gearbox 55, a double-acting lead screw 56, and clamping plates 57. Guide blocks 51 are slidably mounted on both the front and rear sides of the guide rail 41, and rollers 52 are rotatably connected to each guide block 51, allowing them to roll on the guide rail 41. Mounting plates 53 are rotatably connected to the bottom of each guide block 51. A sliding rod 44 slidably passes through the mounting plate 53, allowing the mounting plate 53 to move left and right. The outer side of the mounting plate 53 is equipped with... The third motor 54 and the mounting plate 53 are both bolted to the lower part of the second gearbox 55. The second gearbox 55 has one input end and two output ends. The input end of the second gearbox 55 is connected to the output shaft of the third motor 54. Both output ends of the second gearbox 55 are connected to a double-acting screw 56. Two clamping plates 57 are threaded between the two double-acting screws 56 on the front side and two clamping plates 57 are also threaded between the two double-acting screws 56 on the rear side. The clamping plates 57 are used to clamp the bags containing raw materials.

[0033] like Figure 8 As shown, it also includes raised strips 8. The bottom of the guide rail 41 is connected to both the front and rear sides of the raised strips 8. When the roller 52 moves to the right, it will contact the raised strips 8. The raised strips 8 can make the roller 52 vibrate.

[0034] The operator can connect the feed pipe of the PVC sheet production equipment to the bottom of the loading box 1, then place the raw material on the bracket 35, and control the output shaft of the third motor 54 to rotate forward. The third motor 54 drives the double-headed screw 56 to rotate forward through the second gearbox 55. The double-headed screw 56 drives the clamping plate 57 to move outward. After the clamping plate 57 opens, the operator closes the third motor 54, and then controls the output shaft of the first motor 32 to rotate forward. The first motor 32 drives the first screw 34 to rotate forward through the first gearbox 33. The first screw 34 drives the bracket 35 to move upward, and the bracket 35 conveys the raw material upward. When the bag containing the raw material is between the clamping plates 57, the operator closes the first motor 32, and then controls the output shaft of the third motor 54 to rotate in reverse. The third motor 54 drives the output shaft of the second gearbox 54 to rotate in reverse through the second gearbox 35. Gearbox 55 drives the double-acting lead screw 56 to reverse, which in turn drives the clamping plate 57 to move inward, clamping the bag containing the raw material. After clamping, the third motor 54 is turned off, and then the output shaft of the first motor 32 is controlled to reverse. The first motor 32 drives the first lead screw 34 to reverse through the first gearbox 33. The first lead screw 34 drives the bracket 35 to move downward. After the bracket 35 moves downward and resets, the first motor 32 is turned off, and then the output shaft of the second motor 42 is controlled to rotate forward. The second motor 42 drives the second lead screw 43 to rotate forward, which in turn drives the slide bar 44 to move to the right. The slide bar 44 drives the mounting plate 53 to move to the right, and the mounting plate 53 drives the guide block 51 and the clamping plate 57 to move to the right, thereby moving the raw material to the right. When the bag containing the raw material and the blade 4... When contact occurs, the blade 45 can puncture the bag containing the raw material, allowing the material inside to fall into the loading box 1. The material then enters the PVC sheet production equipment through the loading box 1. After the guide block 51 moves a certain distance to the right, it is guided by the guide rail 41 and moves inward. The mounting plate 53 slides inward on the slide rod 44, causing the bag containing the raw material to droop, allowing the material inside to fall more effectively into the loading box 1. Simultaneously, the guide block 51 can also drive the roller 52 to move to the right. The roller 52's rightward movement will contact the protruding strip 8, causing the roller 52 to vibrate. This vibration of the roller 52 will cause the guide block 51 to vibrate, which in turn will cause the mounting plate 53 to vibrate. This vibration of the bag containing the raw material will then remove any remaining residue. When the material falls into the loading box 1 and the bag containing the raw material moves to the right side of the loading box 1, the operator turns off the second motor 42 and then controls the output shaft of the third motor 54 to rotate forward, causing the clamping plate 57 to move outward, releasing the bag containing the raw material. The bag falls to the ground, and then the operator turns off the third motor 54 and controls the output shaft of the second motor 42 to rotate in reverse. The second motor 42 drives the second lead screw 43 to rotate in reverse, and the second lead screw 43 drives the slide bar 44 to move to the left. The guide block 51 and the clamping plate 57 move to the left accordingly. After the guide block 51 moves a certain distance to the left, it is guided by the guide rail 41 and moves outward to reset. The mounting plate 53 slides outward on the slide bar 44 to reset. After the clamping plate 57 moves to the left and resets, the guide block 51 moves outward to reset.The operator shuts off the second motor 42 and then repeats the above operation to continue feeding raw materials into the PVC sheet production equipment. The feeding process is automated, making the operator's job easier.

[0035] Second implementation method

[0036] Based on the first implementation method, such as Figure 1 and Figure 6 As shown, it also includes a material blocking mechanism 6, which can block the raw material. The material blocking mechanism 6 includes a connecting block 61 and a protective frame 62. The front and rear sides of the fixed frame 31 are connected by welding two connecting blocks 61. The protective frame 62 is rotatably connected between the two connecting blocks 61 on the front side and the protective frame 62 is also rotatably connected between the two connecting blocks 61 on the rear side. The protective frame 62 can block the raw material on the bracket 35 and prevent the raw material on the bracket 35 from falling off.

[0037] like Figure 6 As shown, it also includes magnetic strips 9. Magnetic strips 9 are connected to the inner side of the protective frame 62 by screws, and the two magnetic strips 9 attract each other.

[0038] The staff pulls the protective frame 62 outward to open it, the two magnetic strips 9 detach, and then places the raw material on the tray 35. Then, the staff pushes the protective frame 62 inward to close it. The two magnetic strips 9 attract each other, thus fixing the protective frame 62 in place. The protective frame 62 can block the raw material on the tray 35 and prevent it from falling off the tray 35.

[0039] like Figure 7 As shown, it also includes a collection box 7. The collection box 7 is bolted to the right side of the support frame 2. The collection box 7 can collect bags containing raw materials.

[0040] like Figure 7 As shown, it also includes a door 10. The front and rear sides of the lower right side of the collection box 7 are rotatably connected to the door 10, which can block the bag containing the raw materials.

[0041] After all the raw materials in the bag are put into the material box 1, the clamp 57 loosens the bag containing the raw materials, and the bag falls into the collection box 7 for easy collection by the staff. After the collection box 7 is full of bags, the staff can open the box door 10 and take out the bags. After all the bags are taken out, the box door 10 is closed.

[0042] Third implementation method

[0043] Based on the first embodiment, the blade 45 is inclined and the cutting edge of the blade 45 faces upward. A drive cylinder is provided on the loading box 1 to drive the blade 45 to move in the horizontal direction, and an inclined surface is provided on the back of the blade 45 that matches the inclined bottom surface of the loading box 1, so that the cutting movement of the blade 45 is more stable and smooth.

[0044] Fourth implementation method

[0045] like Figure 9 As shown, based on the third embodiment, the inner bottom of the loading box 1 has four inclined surfaces. A baffle 11 is hinged to the upper side of each of the four inclined surfaces at the inner bottom of the loading box 1. The lower end of the baffle 11 extends to the lower side of the corresponding inclined surface, and an acute angle space is formed between the baffle 11 and the corresponding inclined surface. The gap of the acute angle space gradually decreases from top to bottom.

[0046] An annular tube 12 is provided inside the loading box 1, and the annular tube 12 sits on the upper top side of the baffle 11. An air outlet is provided on the annular tube 12 that communicates with the upper side of each acute angle space.

[0047] Several air guide slots 13 are provided at the lower end of the lower surface of the baffle 11, which are connected to the acute angle space.

[0048] The annular pipe 12 is connected to the main air supply pipe, and the main air supply pipe injects gas into the annular pipe 12. The gas is discharged from the air outlet of the annular pipe 12 into the acute angle space, and finally discharged from the lower discharge end of the loading box 1 through the air guide duct 13.

[0049] The above method can form a pneumatic agitation of the raw materials. At the same time, under the action of air pressure, the baffle 11 can also be driven to swing relative to the inclined surface to achieve the purpose of material vibration.
