Description

Technical Field

[0001] The present invention relates to the technical field of disposable plastic cup production equipment, in particular to disposable plastic cup production equipment and a production method thereof. Background Art

[0002] Disposable plastic cups are a type of plastic cup that is easy to carry and use, and is inexpensive. They are a common drinking tool in many homes and public places.

[0003] Most disposable plastic cup production equipment in the existing technology heats plastic particles and stretches them into a plastic belt for conveying and molding when molding plastic cups. The plastic belt is relatively viscous and has a high temperature before molding the plastic cups. When the plastic cups are compression molded, the mold easily adheres the plastic to the mold during compression molding. The residual plastic in the mold affects the compression molding effect, thereby reducing the quality of the plastic cup production. Summary of the Invention

Electromagnets II are respectively fixedly installed at the included angles of the polygon-shaped blocks. The electromagnet I is adapted to the plurality of electromagnets II.

[0012] Furthermore, a shearing mechanism is arranged at the top of the two fixing plates. The shearing mechanism comprises a mounting frame fixedly installed at the tops of the two fixing plates. A strip-shaped mounting plate is arranged in the mounting frame. A plurality of upper molds are fixedly installed at the bottom of the strip-shaped mounting plate. The plurality of upper molds are respectively adapted to a plurality of lower mold grooves. A limiting plate is slidably sleeved on the plurality of upper molds. Circular cutters are respectively sleeved outside the plurality of upper molds. The tops of the plurality of circular cutters are fixedly connected with the limiting plate. Two shearing springs are fixedly installed at the top of the limiting plate. The tops of the two shearing springs are both fixedly connected with the strip-shaped mounting plate.

[0013] Furthermore, a transmission mechanism is arranged at the top of the strip-shaped mounting plate. The transmission mechanism comprises a limiting strip-shaped plate fixedly installed at the top of the strip-shaped mounting plate. Strip-shaped limiting plates are respectively fixedly installed on the left and right sides of the mounting frame. L-shaped limiting rods are respectively fixedly installed on the sides of the two strip-shaped limiting plates close to each other. The two L-shaped limiting rods penetrate through the limiting strip-shaped plate and are both slidably connected with the limiting strip-shaped plate. The tops of the two L-shaped limiting rods are both fixedly connected with the mounting frame. A transmission rod is hinged on the semi-gear. The top of the transmission rod is hinged with the limiting strip-shaped plate. An L-shaped transmission rod is fixedly installed on the back of the limiting strip-shaped plate. The bottom end of the L-shaped transmission rod extends into the cooling water tank and is slidably connected with the cooling water tank. The bottom end of the L-shaped transmission rod is fixedly connected with the piston plate.

[0014] Furthermore, the production method of the disposable plastic cup production equipment is used as follows:

[0015] S1: During the transmission of the thermoplastic tape, the driving motor is started, the driving motor drives the rotating shaft to rotate, the rotating shaft drives the half gear to rotate, the half gear drives the gear to rotate, when the tooth block on the half gear leaves the gear, the gear just drives the hollow shaft to rotate, the hollow shaft drives the polygonal block to rotate, and several lower die slots on the top of the polygonal block just stop vertically. Since the polygonal block has five included angles and electromagnet 2 is installed in each included angle, when the lower die slot on the top of the polygonal block stops vertically, it is just perpendicular to the electromagnet 2 in the included angle. At this time, electromagnet 1 on the mold plate will generate suction with electromagnet 2 to prevent the gear from rotating freely after the half gear leaves the gear, and accurately locate the position of the lower die slot;

[0016] S2: When the half gear rotates, the half gear will drive the transmission rod to rotate. When the half gear leaves the gear, the transmission rod will continue to rotate with the half gear. When the half gear rotates one circle, the transmission rod will also rotate one circle. The transmission rod will drive the limiting strip plate to perform an up and down reciprocating motion. The limiting strip plate will perform stable up and down motion on the two L-shaped limiting rods to ensure that the movement trajectory of the limiting strip plate is vertical. When the limiting strip plate moves back and forth, it will drive the upper mold at the bottom of the strip mounting plate to extrude the thermoplastic tape and push the thermoplastic tape into several lower mold grooves for molding and pressing. When the strip mounting plate descends, it will also drive the circular cutter to descend. When the circular cutter contacts the top surface of the polygonal block, it will cut the thermoplastic tape, separating the formed plastic cup from the thermoplastic tape. When the half gear drives the gear to rotate, it will drive the other top surface on the polygonal block to rotate to a vertical position with the electromagnet.

[0017] S3: When the limiting strip plate descends, the L-shaped transmission rod will be driven down, and the L-shaped transmission rod will be driven down to drive the piston plate down. The water in the cooling water tank will enter the T-shaped groove through the water inlet hole, and then lift the T-shaped ring sealing block through the annular perforated plate, so that the water in the cooling water tank flows to the top of the T-shaped ring sealing block. When the limiting strip plate descends to the bottom, the piston plate will also reach the designated position. At this time, under the elastic force of the closing spring, the T-shaped ring sealing block will be pulled down to prepare for heat dissipation of the lower die groove.

[0018] S4: When the limiting strip plate drives the L-shaped transmission rod to rise, it will also drive the piston plate to rise. During the rising process, due to the downward pressure of water pressure, the T-shaped ring sealing block will be closer to the piston plate to avoid water leakage. The piston plate will drive the water to rise and flow into the cooling chamber from the hollow shaft close to the drive motor, so that the water in the cooling water tank and the water in the cooling chamber that absorbs the temperature of the lower mold groove are neutralized, so that the lower mold groove can be cooled more quickly. Cooling the lower mold groove can reduce the adhesion between the thermoplastic belt and the mold surface, making it easier to detach from the mold, and the amount of water entering the cooling chamber increases. The corresponding water will flow out from the hollow shaft close to the half gear, and the heat will be discharged through several heat dissipation holes when the water flows out.

[0019] The present invention has the following beneficial effects:

[0020] (1) The disposable plastic cup production equipment of the present invention, when the limiting strip plate drives the L-shaped transmission rod to rise, it will also drive the piston plate to rise. During the rising process, due to the downward pressure of water pressure, the T-shaped ring sealing block will be closer to the piston plate to avoid water leakage. The piston plate will drive the water to rise so that the water flows from the hollow shaft near the drive motor into the cooling chamber, so that the water in the cooling water tank and the water in the cooling chamber that absorbs the temperature of the lower mold groove are neutralized, so that the lower mold groove can be cooled more quickly. Cooling the lower mold groove can reduce the adhesion between the thermoplastic tape and the mold surface, making it easier to separate from the mold, and the amount of water entering the cooling chamber increases. The corresponding water will flow out from the hollow shaft near the half gear. When the water flows out, the heat will be discharged through a number of heat dissipation holes, further improving the cooling treatment of the water;

[0021] (2) The disposable plastic cup production equipment of the present invention drives the L-shaped transmission rod to descend during the process of the limiting strip plate descending, and the descending of the L-shaped transmission rod drives the piston plate to descend, and the water in the cooling water tank enters the T-shaped groove through the water inlet hole, and then lifts the T-shaped ring sealing block through the annular perforated plate, so that the water in the cooling water tank flows to the top of the T-shaped ring sealing block. When the limiting strip plate descends to the bottom, the piston plate also reaches the specified position. At this time, under the elastic force of the closing spring, the T-shaped ring sealing block will be pulled downward to prepare for heat dissipation of the lower mold groove;

[0022] (3) The disposable plastic cup production equipment of the present invention starts the driving motor during the transmission of the thermoplastic belt, and the driving motor drives the rotating shaft to rotate, the rotating shaft drives the half gear to rotate, and the half gear drives the gear to rotate. When the tooth block on the half gear leaves the gear, the gear just drives the hollow shaft to rotate, and the hollow shaft also drives the polygonal block to rotate. The several lower mold grooves on the top of the polygonal block just stop vertically. Since the polygonal block has five angles and electromagnet 2 is installed in each angle, when the lower mold groove on the top of the polygonal block stops vertically, it is just perpendicular to the electromagnet 2 in the angle. At this time, electromagnet 1 on the mold plate will generate suction with electromagnet 2 to prevent the gear from rotating freely after the half gear leaves the gear, and accurately locate the position of the lower mold groove;

[0023] (4) The disposable plastic cup production equipment of the present invention, when the half gear rotates, the half gear will drive the transmission rod to rotate. When the half gear leaves the gear, the transmission rod will continue to rotate with the half gear. When the half gear rotates one circle, the transmission rod will also rotate one circle. The transmission rod will drive the limiting strip plate to perform an up and down reciprocating motion. The limiting strip plate will perform a stable up and down motion on the two L-shaped limiting rods to ensure that the movement trajectory of the limiting strip plate is vertical. When the limiting strip plate moves back and forth, it will drive the upper mold at the bottom of the strip mounting plate to extrude the thermoplastic tape and push the thermoplastic tape into several lower mold grooves for molding and pressing. When the strip mounting plate descends, it will also drive the circular cutter to descend. When the circular cutter contacts the top surface of the polygonal block, it will cut the thermoplastic tape, so that the formed plastic cup is separated from the thermoplastic tape. When the half gear drives the gear to rotate, it will drive the other top surface on the polygonal block to rotate to a vertical position with the electromagnet.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] See also Figures 1-8 As shown, the present invention is a disposable plastic cup production device, comprising two fixed plates 1, a cooling mechanism 01 is provided below the two fixed plates 1, the cooling mechanism 01 comprises a cooling water tank 2 provided below the two fixed plates 1, a hollow shaft 3 is rotatably mounted on each side of the cooling water tank 2 close to each other, and further comprising:

[0038] A polygonal block 4 is fixedly installed on the side where the two hollow shafts 3 are close to each other. Several lower mold grooves 5 are opened on the outer wall of the polygonal block 4. A cooling cavity 6 is opened in the polygonal block 4. Several heat dissipation holes 7 are opened on the top of the cooling water tank 2. A thermoplastic belt 8 is provided above the fixed plate 1.

[0039] like Figure 4 As shown, an adaptation mechanism 02 is provided in the cooling water tank 2, and the adaptation mechanism 02 includes a piston plate 9 slidably installed in the cooling water tank 2, a T-slot 10 is provided in the piston plate 9, a plurality of water inlet holes 11 are provided on the bottom inner wall of the T-slot 10, and an annular perforated plate 12 is slidably installed in the T-slot 10.

[0040] The L-shaped transmission rod 35 descends and drives the piston plate 9 to descend. The water in the cooling water tank 2 enters the T-shaped slot 10 through the water inlet hole 11 and then lifts the T-shaped ring sealing block 15 through the annular perforated plate 12.

[0041] like Figure 4 As shown, a closing mechanism 03 is provided in the T-slot 10, and the closing mechanism 03 includes a plurality of closing springs 14 fixedly mounted on the inner wall of the bottom of the T-slot 10, and a T-shaped ring sealing block 15 is fixedly mounted on the top of the plurality of closing springs 14. The T-shaped ring sealing block 15 is slidingly connected to the T-slot 10, and the top of the T-shaped ring sealing block 15 extends to the outside of the piston plate 9.

[0042] The water in the cooling water tank 2 flows to the top of the T-shaped ring sealing block 15. When the limiting strip plate 31 drops to the bottom, the piston plate 9 will also reach the specified position. At this time, under the elastic force of the closing spring 14, the T-shaped ring sealing block 15 will be pulled downward to prepare for heat dissipation of the lower mold groove 5.

[0043] like Figure 5 and Figure 6 As shown, a positioning mechanism 04 is provided at the bottom of the two fixed plates 1, and the positioning mechanism 04 includes mounting plates 16 fixedly installed on the bottom of the two fixed plates 1 respectively, and strip plates 17 are fixedly installed on the front and back of the two mounting plates 16 respectively, and the two hollow shafts 3 respectively penetrate the strip plates 17 and are rotatably connected to the two strip plates 17 respectively, and a rotating shaft 18 is rotatably installed on the two strip plates 17, and the rotating shaft 18 penetrates the two strip plates 17, and a half gear 19 is fixedly provided on the rotating shaft 18, and a gear 20 is fixedly provided on the corresponding hollow shaft 3, and the gear 20 is engaged with the half gear 19, and a driving motor 21 is fixedly installed on the back of the corresponding strip plate 17, and the output shaft of the driving motor 21 is fixedly connected to the rotating shaft 18.

[0044] The rotating shaft 18 drives the half gear 19 to rotate, and the half gear 19 drives the gear 20 to rotate. When the tooth block on the half gear 19 leaves the gear 20, the gear 20 just drives the hollow shaft 3 to rotate.

[0045] As shown Figure 5 in the figure, a stabilizing mechanism 05 is provided at the bottom of the two strip plates 17. The stabilizing mechanism 05 includes a U-shaped plate 22 fixedly installed at the bottom of the two strip plates 17. An electromagnet 23 is fixedly installed on the U-shaped plate 22. Electromagnets 24 are respectively fixedly installed at the included angles of the polygon block 4. The electromagnet 23 is adapted to a plurality of electromagnets 24.

[0046] The polygon block 4 has five included angles and an electromagnet 24 is installed in each included angle. When the lower die groove 5 at the top of the polygon block 4 stops vertically, the electromagnet 24 in the included angle will be vertical exactly. At this time, the electromagnet 23 on the U-shaped plate 22 will generate suction force with the electromagnet 24, avoiding the free rotation of the gear 20 after the half gear 19 leaves the gear 20, and accurately positioning the position of the lower die groove 5.

[0047] As shown Figure 7 in the figure, a shearing mechanism 06 is provided at the top of the two fixing plates 1. The shearing mechanism 06 includes a mounting frame 25 fixedly installed at the top of the two fixing plates 1. A strip-shaped mounting plate 26 is arranged inside the mounting frame 25. A plurality of upper dies 27 are fixedly installed at the bottom of the strip-shaped mounting plate 26. The plurality of upper dies 27 are respectively adapted to a plurality of lower die grooves 5. A limiting plate 28 is slidably sleeved on the plurality of upper dies 27. Circular cutters 29 are respectively sleeved outside the plurality of upper dies 27. The tops of the plurality of circular cutters 29 are fixedly connected to the limiting plate 28. Two shearing springs 30 are fixedly installed at the top of the limiting plate 28. The tops of the two shearing springs 30 are fixedly connected to the strip-shaped mounting plate 26.

[0048] When the limiting strip plate 31 reciprocates, it will drive the upper die 27 at the bottom of the strip-shaped mounting plate 26 to extrude the thermoplastic tape 8 and push the thermoplastic tape 8 into a plurality of lower die grooves 5 for forming and pressing. When the strip-shaped mounting plate 26 descends, it will also drive the circular cutter 29 to descend. When the circular cutter 29 contacts the top surface of the polygon block 4, it will cut the thermoplastic tape 8, separating the formed plastic cup from the thermoplastic tape 8. When the half gear 19 drives the gear 20 to rotate, it will drive another top surface of the polygon block 4 to rotate to the vertical position of the electromagnet 23.

[0049] As shown Figure 6 and Figure 7As shown, a transmission mechanism 07 is provided on the top of the strip mounting plate 26, and the transmission mechanism 07 includes a limiting strip plate 31 fixedly mounted on the top of the strip mounting plate 26, and a strip limiting plate 32 is fixedly mounted on the left and right sides of the mounting frame 25, and an L-shaped limiting rod 33 is fixedly mounted on the side where the two strip limiting plates 32 are close to each other, and the two L-shaped limiting rods 33 pass through the limiting strip plate 31 and are slidably connected to the limiting strip plate 31, and the top ends of the two L-shaped limiting rods 33 are fixedly connected to the mounting frame 25, and a transmission rod 34 is hingedly mounted on the half gear 19, and the top end of the transmission rod 34 is hingedly connected to the limiting strip plate 31, and an L-shaped transmission rod 35 is fixedly mounted on the back side of the limiting strip plate 31, and the bottom end of the L-shaped transmission rod 35 extends into the cooling water tank 2 and is slidably connected to the cooling water tank 2, and the bottom end of the L-shaped transmission rod 35 is fixedly connected to the piston plate 9.

[0050] When the half gear 19 rotates, the half gear 19 drives the transmission rod 34 to rotate. When the half gear 19 leaves the gear 20, the transmission rod 34 continues to rotate with the half gear 19. When the half gear 19 rotates one circle, the transmission rod 34 also rotates one circle, and the transmission rod 34 drives the limiting strip plate 31 to perform an up and down reciprocating motion.

[0051] like Figure 1-8 As shown, the production method of disposable plastic cup production equipment is as follows:

[0052] S1: During the transmission of the thermoplastic belt 8, the driving motor 21 is started, the driving motor 21 drives the rotating shaft 18 to rotate, the rotating shaft 18 drives the half gear 19 to rotate, and the half gear 19 drives the gear 20 to rotate. When the tooth block on the half gear 19 leaves the gear 20, the gear 20 just drives the hollow shaft 3 to rotate, and the hollow shaft 3 drives the polygonal block 4 to rotate. The several lower mold grooves 5 on the top of the polygonal block 4 just stop vertically. Since the polygonal block 4 has five included angles and an electromagnet 2 24 is installed in each included angle, when the lower mold groove 5 on the top of the polygonal block 4 stops vertically, it is just perpendicular to the electromagnet 2 24 in the included angle. At this time, the electromagnet 1 23 on the mold plate 22 will generate suction with the electromagnet 2 24 to prevent the gear 20 from rotating freely after the half gear 19 leaves the gear 20, and accurately locate the position of the lower mold groove 5;

[0053] S2: When the half gear 19 rotates, the half gear 19 drives the transmission rod 34 to rotate. When the half gear 19 leaves the gear 20, the transmission rod 34 will continue to rotate with the half gear 19. When the half gear 19 rotates one circle, the transmission rod 34 will also rotate one circle. The transmission rod 34 will drive the limiting strip plate 31 to perform an up and down reciprocating motion. The limiting strip plate 31 will perform a stable up and down motion on the two L-shaped limiting rods 33 to ensure that the motion trajectory of the limiting strip plate 31 is vertical. When the strip mounting plate 26 moves back and forth, it drives the upper mold 27 at the bottom of the strip mounting plate 26 to extrude the thermoplastic tape 8 and push the thermoplastic tape 8 into a plurality of lower mold grooves 5 for molding. When the strip mounting plate 26 descends, it also drives the circular cutter 29 to descend. When the circular cutter 29 contacts the top surface of the polygonal block 4, it cuts the thermoplastic tape 8, separating the molded plastic cup from the thermoplastic tape 8. When the half gear 19 drives the gear 20 to rotate, it drives the other top surface of the polygonal block 4 to rotate to a perpendicular position with respect to the electromagnet 23.

[0054] S3: When the limiting strip plate 31 descends, the L-shaped transmission rod 35 will be driven to descend, and the descending of the L-shaped transmission rod 35 will drive the piston plate 9 to descend, and the water in the cooling water tank 2 will enter the T-shaped groove 10 through the water inlet hole 11, and then lift the T-shaped ring sealing block 15 through the annular perforated plate 12, so that the water in the cooling water tank 2 flows to the top of the T-shaped ring sealing block 15. When the limiting strip plate 31 descends to the bottom, the piston plate 9 will also reach the designated position. At this time, under the elastic force of the closing spring 14, the T-shaped ring sealing block 15 will be pulled downward to prepare for heat dissipation of the lower die groove 5;

[0055] S4: When the limiting strip plate 31 drives the L-shaped transmission rod 35 to rise, it will also drive the piston plate 9 to rise. During the rising process, due to the downward pressure of water pressure, the T-shaped ring sealing block 15 will be closer to the piston plate 9 to avoid water leakage. The piston plate 9 will drive the water to rise and flow into the cooling chamber 6 from the hollow shaft 3 near the drive motor 21, so that the water in the cooling water tank 2 and the water in the cooling chamber 6 that absorbs the temperature of the lower mold groove 5 are neutralized, so that the lower mold groove 5 can be cooled more quickly. Cooling the lower mold groove 5 can reduce the adhesion between the thermoplastic belt 8 and the mold surface, making it easier to detach from the mold, and the amount of water entering the cooling chamber 6 increases. The corresponding water will flow out from the hollow shaft 3 near the half gear 19, and the heat will be discharged through several heat dissipation holes 7 when the water flows out.

2. The production method of disposable plastic cup production equipment according to claim 1, characterized in that: Here’s how to use it: S1: During the transmission of the thermoplastic tape (8), the driving motor (21) is started, the driving motor (21) drives the rotating shaft (18) to rotate, the rotating shaft (18) drives the half gear (19) to rotate, the half gear (19) drives the gear (20) to rotate, and when the tooth block on the half gear (19) leaves the gear (20), the gear (20) just drives the hollow shaft (3) to rotate, and the hollow shaft (3) also drives the polygonal block (4) to rotate, and the multiple lower die grooves (5) on the top of the polygonal block (4) are rotated. ) is exactly stopped vertically. Since the polygonal block (4) has five included angles and electromagnet 2 (24) is installed in each included angle, when the top of the polygonal block (4) is stopped vertically, the electromagnet 2 (24) in the included angle is exactly vertical. At this time, electromagnet 1 (23) on the mold plate (22) and electromagnet 2 (24) generate suction force to prevent the gear (20) from rotating freely after the half gear (19) leaves the gear (20), and accurately locate the position of the lower die groove (5); S2: When the half gear (19) rotates, the half gear (19) drives the transmission rod (34) to rotate. When the half gear (19) leaves the gear (20), the transmission rod (34) continues to rotate with the half gear (19). When the half gear (19) rotates one circle, the transmission rod (34) also rotates one circle. The transmission rod (34) drives the limit strip plate (31) to perform an up and down reciprocating motion. The limit strip plate (31) performs a stable up and down motion on the two L-shaped limit rods (33) to ensure that the motion trajectory of the limit strip plate (31) is vertical. When the limit strip plate (31) moves up and down, the limit strip plate (31) moves back and forth. When the strip mounting plate (26) moves back and forth, the upper mold (27) at the bottom of the strip mounting plate (26) will be driven to extrude the thermoplastic tape (8) and push the thermoplastic tape (8) into a plurality of lower mold grooves (5) for molding and pressing. When the strip mounting plate (26) is lowered, the circular cutter (29) will also be driven to descend. When the circular cutter (29) contacts the top surface of the polygonal block (4), the thermoplastic tape (8) will be cut, so that the formed plastic cup is separated from the thermoplastic tape (8). When the half gear (19) drives the gear (20) to rotate, it will drive the other top surface of the polygonal block (4) to rotate to a vertical position with respect to the electromagnet (23). S3: During the process of the limiting strip plate (31) descending, the L-shaped transmission rod (35) will be driven to descend, and the descent of the L-shaped transmission rod (35) will drive the piston plate (9) to descend, and the water in the cooling water tank (2) will enter the T-shaped groove (10) through the water inlet hole (11), and then the T-shaped ring sealing block (15) will be lifted up through the annular perforated plate (12), so that the water in the cooling water tank (2) will flow to the top of the T-shaped ring sealing block (15). When the limiting strip plate (31) descends to the bottom, the piston plate (9) will also reach the specified position. At this time, under the elastic force of the closing spring (14), the T-shaped ring sealing block (15) will be pulled downward to prepare for heat dissipation of the lower die groove (5); S4: When the limiting strip plate (31) drives the L-shaped transmission rod (35) to rise, it also drives the piston plate (9) to rise. During the rising process, due to the downward pressure of the water pressure, the T-shaped ring seal block (15) will be closer to the piston plate (9) to avoid water leakage. The piston plate (9) will drive the water to rise so that the water flows from the hollow shaft (3) near the drive motor (21) into the cooling chamber (6), so that the water in the cooling water tank (2) and the water in the cooling chamber (6) that absorbs the temperature of the lower mold groove (5) are neutralized, so that the lower mold groove (5) can be cooled more quickly. Cooling the lower mold groove (5) can reduce the adhesion between the thermoplastic tape (8) and the mold surface, making it easier to detach from the mold, and the amount of water entering the cooling chamber (6) increases. The corresponding water will flow out from the hollow shaft (3) near the half gear (19). When the water flows out, the heat will be discharged through a number of heat dissipation holes (7).
