Description

Technical Field

[0001] This utility model relates to the field of plastic product fixing technology, specifically a plastic product fixing device. Background Technology

[0002] Plastic products are made of plastic, which is a high molecular weight compound polymerized through addition or condensation polymerization. Commonly known as plastic or resin, its composition and shape can be freely changed. It consists of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. When processing plastic products, it is generally necessary to fix the plastic products with a fixing device before cutting and other operations are carried out.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] A device for fixing plastic products, such as Figures 1-6As shown, the system includes a base plate 1. Movable plates 5 are movably installed on the upper surface of the base plate 1 near both ends. A bearing plate 7 is movably installed above each of the two movable plates 5. A partition 32 is fixedly installed on the upper surface of the bearing plate 7. A fixing mechanism is provided on the upper surface of the bearing plate 7. An annular plate 6 is rotatably connected to the upper surface of the movable plate 5 via a shaft, and the annular plate 6 is fixedly connected to the bearing plate 7 via a shaft. A collection box 21 is fixedly installed on the bottom surface of the base plate 1. A reciprocating screw 2 is rotatably connected to the upper surface of the base plate 1 near both ends. Movable blocks 3 are sleeved on the outside of each of the four reciprocating screws 2. Flexible curtains 22 are fixedly connected to the outer walls of the two movable plates 5. The fixing mechanism includes a semi-circular fixing plate 15, an upper clamping plate 10, and a lower clamping plate 14. The semi-circular fixing plate 15 is fixedly installed on the upper surface of the bearing plate 7, and the upper clamping plate 10 and the lower clamping plate 14 are movably installed on one side of the partition 32.

[0032] Two motors are installed at one end of the base plate 1, and the output ends of the two motors are respectively connected to two reciprocating lead screws 2. Several through holes are opened through the upper surface of the annular plate 6. A fixing bolt 31 is inserted into one of the round holes. A screw groove is opened on the upper surface of the movable plate 5 and located directly below the fixing bolt 31. The screw groove fits with the fixing bolt 31. The upper end of the movable block 3 is fixedly connected to the movable plate 5.

[0033] A slot 4 is provided through the upper surface of the base plate 1 near the middle position. Two winding shafts 23 are rotatably connected inside the collection box 21, and one end of each of the two flexible curtains 22 passes through the slot 4 and is fixedly connected to the two winding shafts 23 respectively.

[0034] A double-threaded rod 8 is rotatably connected to the outer wall of the partition 32. Two movable blocks 9 are sleeved on the outside of the double-threaded rod 8. One movable block 9 is fixedly connected to the upper clamping plate 10, and the other movable block 9 is fixedly connected to the lower clamping plate 14. A motor is installed on the upper surface of the partition 32, and the output end of the motor is connected to the double-threaded rod 8. The motor drives the double-threaded rod 8 to rotate, which drives the two movable blocks 9 to move, so that the upper clamping plate 10 and the lower clamping plate 14 move closer to each other, vertically clamping both ends of the plastic product.

[0035] Adjusting rods 11 are inserted into both outer side walls of the lower clamping plate 14. One end of each adjusting rod 11 is fixedly connected to a limiting plate 12. Several fixing holes are opened on the upper surface of the adjusting rod 11. A fixing nail is inserted into the upper surface of the lower clamping plate 14, and the fixing nail fits into the fixing hole. By passing the fixing nail through the lower clamping plate 14 and inserting it into the corresponding fixing hole, the position of the adjusting rod 11 and the limiting plate 12 can be fixed.

[0036] A slot 19 is provided through the upper surface of the semi-circular fixing plate 15. A T-shaped insert plate 18 is inserted into one end of the semi-circular fixing plate 15. A fixing groove is provided on the inner wall of the slot 19, and the fixing groove fits into one end of the T-shaped insert plate 18. Two fixing nails are inserted into the outer wall of the T-shaped insert plate 18. Fixing holes are provided on one end of the semi-circular fixing plate 15 near the two fixing nails, and the fixing holes fit into the fixing nails. The two fixing nails are inserted through the T-shaped insert plate 18 into the fixing holes to fix the position of the T-shaped insert plate 18.

[0037] A winding shaft 17 is rotatably connected to the upper surface of the bearing plate 7 near the semi-circular fixing plate 15. A flexible fixing strip 16 is wound around the outside of the winding shaft 17, and one end of the flexible fixing strip 16 passes through the slot 19 and is rotatably connected to one end of the semi-circular fixing plate 15. A handle 20 is fixedly connected to one end of the winding shaft 17. Rotating the handle 20 will drive the winding shaft 17 to rotate, which can wind up the flexible fixing strip 16.

[0038] In use, first adjust the distance between the two bearing plates 7 according to the length of the plastic product to be fixed. During adjustment, the two motors drive the four reciprocating screws 2 to rotate, which in turn moves the movable blocks 3, causing the two movable plates 5 to move closer to each other. After adjustment, place both ends of the plastic product into the two lower clamping plates 14. Then, drive the double-headed threaded rod 8 to rotate, which in turn moves the two movable blocks 9, causing the upper clamping plate 10 and the lower clamping plate 14 to move closer to each other, vertically clamping both ends of the plastic product. Then, push the two limiting plates 12 with the two adjusting rods 11, so that the two limiting plates 12 horizontally clamp and limit both ends of the plastic product. The position of the adjusting rod 11 and the limiting plate 12 can be fixed by inserting the fixing nail through the lower clamping plate 14 into the corresponding fixing hole. Through the above operation, plastic products of different lengths can be clamped and fixed, and clamped and fixed from both vertical and horizontal directions, making the fixing effect more stable.

[0039] When the plastic product to be fixed is cylindrical, the two annular plates 6 can be rotated, causing the two bearing plates 7 to rotate, so that the two semi-circular fixing plates 15 are opposite each other. Then, one end of the fixing bolt 31 is inserted into the corresponding through hole and rotated into the screw groove to fix the position of the annular plate 6, thereby fixing the position of the bearing plate 7. At this time, the two ends of the cylindrical plastic product to be fixed can be placed into the two semi-circular fixing plates 15 respectively. Then, the handle 20 is rotated to drive the winding shaft 17 to rotate, which can wind up the flexible fixing band 16, so that the flexible fixing band 16 is pressed tightly against the surface of the plastic product. One end of the T-shaped insert 18 passes through the slot 19 and presses against the outer wall of the semi-circular fixing plate 15, pressing the outer wall of the semi-circular fixing plate 15 into the fixing groove. Then, two fixing nails are inserted through the T-shaped insert 18 into the fixing holes to fix the position of the T-shaped insert 18. This fixes a portion of the semi-circular fixing plate 15 in the slot 19, completing the fixation of one end of the plastic product. Similarly, the other end of the plastic product can be fixed, thus achieving the fixation of cylindrical plastic products. Through the above operations, the fixing device can adapt to the fixing operation of cylindrical plastic products, effectively improving its applicability.

[0040] The outer wall of the collection box 21 is connected to a movable door 29 via a hinge. Inside the collection box 21 and located between two winding shafts 23, a cleaning roller 25 is rotatably connected. One end of each of the two winding shafts 23 is fixedly connected to a gear 24 via a shaft. Inside the collection box 21, two guide shafts 26 are rotatably connected. The two guide shafts 26 limit the transmission position of the flexible curtain 22.

[0041] An electric telescopic rod 28 is installed on the outer side wall of the base plate 1 near the middle. An installation plate 30 is fixedly connected to the bottom end of the electric telescopic rod 28. Two gears 27 are rotatably connected to the side of the installation plate 30 near the collection box 21 via a shaft. The gears 27 mesh with the gear 1 24. Two motors 2 are installed on the other outer side wall of the installation plate 30. The output end of the motors 2 is connected to the gears 27. The electric telescopic rod 28 drives the installation plate 30 to move upward, so that the two gears 27 move away from the gear 1 24, releasing the restriction on the winding shaft 23, so that the flexible curtain 22 wound on the winding shaft 23 can be loosened.

[0042] Specifically, after the plastic product is fixed by the fixing device, it can be processed by cutting and grooving. During the processing, the debris can fall onto the upper surface of the flexible curtain 22, which not only prevents the debris from contacting the reciprocating screw 2 and affecting the normal operation of the reciprocating screw 2 and the moving block 3, but also prevents the debris from contaminating the surface of the base plate 1. When adjusting the position between the two moving plates 5, as the two moving plates 5 move closer to each other, one end of the flexible curtain 22 moves with the moving plate 5, and at the same time, the motor 2 on the mounting plate 30 drives the gear. The rotation of gear 27 drives gear 24 to rotate, causing both winding shafts 23 to rotate simultaneously, winding up the other end of the flexible curtain 22. This keeps the flexible curtain 22 taut and fits well against the upper surface of the base plate 1, blocking debris. Before the two movable plates 5 move away from each other, the electric telescopic rod 28 drives the mounting plate 30 to move upward, causing gears 27 to move away from gear 24, releasing the restriction on the winding shafts 23. This allows the flexible curtain 22 wound on the winding shafts 23 to loosen, avoiding obstruction of the movement of the movable plates 5.

[0043] When the flexible curtain 22 is wound up on the winding shaft 23, the outer wall of the flexible curtain 22 moves in close contact with the cleaning roller 25. The cleaning roller 25 can clean the debris on the flexible curtain 22. The cleaned debris is collected by the collection box 21. Opening the movable door 29 can empty the debris in the collection box 21.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
