Description

Technical Field

[0001] The present invention relates to a rubber band production device, in particular to a binding rubber band coiling device. Background Art

[0002] Rubber bands are common binding stationery. Rubber bands have good toughness and are convenient for binding. Rubber bands are formed by coiling a flat tape. The tape is in the shape of a flat belt. After cutting rubber teeth, it is coiled to obtain a rubber band. Currently, manual coiling is mainly used. When manually coiling, the rubber band needs to be placed in a heated circular groove first, and then the rubber band is pressed into the circular groove by a round rod. The circular groove heats the rubber band to make the rubber band form a circle. Since only half of the circle can be formed each time, multiple formations are required, resulting in low coiling efficiency, high labor intensity of operators, and high processing costs. Summary of the Invention

[0003] To solve the above problems, the present invention provides a binding rubber band coiling device that can automatically coil and succeed in coiling once, with high coiling efficiency and low cost. The specific technical solution is as follows:

[0004] A binding rubber band coiling device includes: a coiling bottom plate; a heating plate fixed on the coiling bottom plate for heating the tape; a coiling cloth located above the heating plate, with both ends of the coiling cloth fixed on the coiling bottom plate, and the coiling cloth is used to place the tape; a cloth turning device slidably installed on the coiling bottom plate and located below the coiling cloth; a coiling rod located above the coiling cloth and opposite to the cloth turning device; a coiling driving device connected to the cloth turning device; a rod changing device installed on the cloth turning device, with the coiling rod installed on the rod changing device and several coiling rods are provided; a blanking device opposite to the coiling rod for taking down the coiled rubber band; and a material moving device located above the coiling cloth. Among them, the material moving device is used to move the tape to the coiling rod, the cloth turning device is used to press the tape against the coiling rod through the coiling cloth, and the coiling driving device is used to drive the cloth turning device and the coiling rod to move on the heating plate, so that the tape is wound around the coiling rod to coil.

[0005] By adopting the above technical solution, first heat the tape to make it soft, then use the material transfer device to push the tape directly below the circular rolling rod, and the tape is parallel to the circular rolling rod. Then, drive the tape to wind around the circular rolling rod through the cloth turning device and the circular rolling cloth. At this time, the tape at the end is wrapped around the circular rolling rod to form a semi-circle. Then, the circular rolling drive device drives the circular rolling rod, the cloth turning device and the tape to move on the heating plate. The rubber ring is completely wound around the circular rolling rod driven by the circular rolling cloth to form a rubber ring, realizing the automatic production of the rubber ring, greatly improving the efficiency of circular rolling and reducing the cost of circular rolling.

[0006] Preferably, the cloth turning device includes: a cloth turning roller located between the heating plate and the circular rolling cloth; and a turning component. The cloth turning roller is installed on the turning component, and the turning component is slidably installed on the circular rolling bottom plate and connected to the circular rolling drive device. The rod changing device is installed on the turning component and is used to drive the cloth turning roller to drive the circular rolling cloth and the rubber ring to wind around the circular rolling rod.

[0007] By adopting the above technical solution, the cloth turning roller facilitates pushing the circular rolling cloth and the tape to wind around the circular rolling rod, ensuring the reliability of circular rolling.

The circular rolling rod is installed on the front rod changing disc, and the circular rolling rods are arranged in a circular array.

[0009] By adopting the above technical solution, the rod changing device drives the circular rolling rod to rotate, enabling the circular rolling rod to work in sequence. The circular rolled rubber ring can just be cooled and shaped. After shaping, the rubber ring is taken off by the blanking device, ensuring the qualified rate of rubber ring forming, improving the product quality, and cooling the rubber ring can effectively prevent the rubber ring from deforming.

[0010] Furthermore, the circular rolling rod is rotatably installed on the front rod changing disc.

[0011] By adopting the above technical solution, the rotatable installation of the circular rolling rod can ensure the synchronous rotation of the tape and the circular rolling rod, prevent the tape from not rotating, avoid producing defective products, and ensure the qualified rate and quality of the product.

The blanking driving block is installed on the blanking driving component and is used to take off the rubber ring on the circular rolling rod through the blanking driving block and the blanking groove.

[0013] By adopting the above technical solution, the blanking of the rubber ring is realized through the blanking slider and the blanking driving block, and the overall structure is simpler and the blanking is more convenient.

[0014] Preferably, it further includes a tensioning device, which is installed on the curling bottom plate and located on one side of the cloth turning device, and is used to tension the curling cloth when the cloth turning device is curling.

[0015] By adopting the above technical solution, when the tensioning device tensions the curling cloth, it can prevent the curling cloth from being loose when the cloth turning device drives the tape to wind around the curling rod, so as to avoid the tape not being able to wind around the curling, and improve the reliability and stability of curling.

[0016] Preferably, it further includes a feeding device, which is located at one end of the heating plate and is used to convey the tape; and a cutting device, which is installed on the feeding device and is used to cut the tape.

[0017] By adopting the above technical solution, the feeding device and the cutting device realize automatic feeding, improve the efficiency, and can automatically cut the material according to the set value, and can produce rubber rings of various specifications.

[0018] Furthermore, it further includes a flattening device, which is located above the heating plate and is arranged opposite to the feeding device, and is used to flatten the cut tape.

[0019] By adopting the above technical solution, the flattening device presses the tape tightly on the heating plate, which can not only improve the heating efficiency, make the tape soften quickly, but also shape the tape to keep it flat, which is convenient for subsequent curling and ensures the quality of curling.

[0020] Furthermore, the material transfer device includes a material transfer bottom plate, which is slidably installed on the curling bottom plate; a lower material transfer cylinder, which is installed on the curling bottom plate and is connected to the material transfer bottom plate; a fixed material transfer rod, which is fixed on the material transfer bottom plate and is located on one side of the feeding device; a lifting assembly, which is installed on the material transfer bottom plate and is located on one side of the fixed material transfer rod; and a movable material transfer rod, which is installed on the lifting assembly and there are several of them.

[0021] By adopting the above technical solution, the fixed material transfer rod does not need to be lifted, and when the material transfer device resets, it will not interfere with the feeding device, avoiding affecting the operation of the feeding device, shortening the beat of the whole process, and improving the efficiency. The lifting assembly facilitates moving the movable material transfer rod to the rear of the tape, and then the lower material transfer cylinder pushes the tape towards the curling rod.

[0022] Multiple movable material rods can continuously push the tape to move, shortening the stroke of the lower material cylinder, improving the feeding efficiency, and making the structure compact.

[0023] Preferably, it further includes a collecting device, which is located on one side of the coiling bottom plate and is arranged opposite to the material discharging device, for collecting the rubber rings and automatically replacing the collecting box.

[0024] By adopting the above technical solution, the rubber rings are automatically collected, which is convenient for transportation, can also reduce the workload of subsequent packaging, and improves the overall efficiency.

[0044] The present invention will be further described below in conjunction with the accompanying drawings.

[0045] Embodiment 1

[0046] As Figures 1 to 17 shown, a binding rubber ring coiling device includes a coiling bottom plate 10, a heating plate 4, a coiled round cloth 31, a cloth turning device, a coiling rod 64, a coiling driving device 681, a rod changing device, a blanking device, a material moving device and a tensioning device.

[0047] The heating plate 4 includes a heating bottom plate 41 and a plurality of heating blocks 42. The heating bottom plate 41 is fixed on the top of the coiling bottom plate 10 through a first connecting column, and there is a gap between the heating bottom plate 41 and the coiling bottom plate 10. The heating blocks 42 are arranged in an array on the heating bottom plate 41. The heating blocks 42 can be heated by an electric heating method, and temperature sensors are installed on the heating blocks 42 to control the heating temperature. A heat insulation layer can be provided between the heating bottom plate 41 and the heating blocks 42. Among them, the material moving device feeds the material in a pushing manner, that is, intermittent feeding. The heating blocks 42 are matched with the feeding rhythm. Intermittent feeding can not only cooperate with coiling, but also enable the tape 8 to have a certain heating time, ensuring that the tape 8 is in a softer state during coiling and can be coiled smoothly.

[0048] The material transfer device includes a material transfer bottom plate 52, a lower material transfer cylinder 51, a movable material transfer rod 57 and a lifting assembly. The material transfer bottom plate 52 is slidably mounted on the top of the rolling bottom plate 10 through a linear guide pair and symmetrically located on both sides of the heating bottom plate 41. The lower material transfer cylinder 51 is fixed to the bottom of the rolling bottom plate 10 and connected to the material transfer bottom plate 52. The lifting assembly includes a material transfer connecting rod 55, a lifting rod 56 and an upper material transfer cylinder 53. One end of the material transfer connecting rod 55 is hinged to the material transfer bottom plate 52 and located at both ends of the material transfer bottom plate 52. The other end of the material transfer connecting rod 55 is hinged to the lifting rod 56. Both ends of the upper material transfer cylinder 53 are respectively hinged to the material transfer bottom plate 52 and one of the material transfer connecting rods 55. The movable material transfer rod 57 is fixed to the lifting rod 56 and four are arranged in an array. The lifting assembly facilitates moving the movable material transfer rod 57 behind the tape 8, and then the lower material transfer cylinder 51 is used to push the tape 8 towards the rolling rod 64. The multiple movable material transfer rods 57 can continuously push the tape 8 to move, shortening the stroke of the lower material transfer cylinder 51, improving the feeding efficiency, and making the structure compact.

[0049] The upper material transfer cylinder 53 is in a retracted state, the movable material transfer rod 57 is movably pressed on the rolling cloth 31, the tape 8 is located on one side of the movable material transfer rod 57, and then the piston rod of the lower material transfer cylinder 51 extends to drive the movable material transfer rod 57 to move towards the rolling rod 64. The movable material transfer rod 57 pushes the tape 8 towards the rolling rod 64. The frontmost movable material transfer rod 57 pushes the tape 8 under the rolling rod 64. Then the piston rod of the upper material transfer cylinder 53 extends to drive the lifting rod 56 and the movable material transfer rod 57 to rise first and move backward, and then descend. The movable material transfer rod 57 is pressed on the rolling cloth 31 and located behind the tape 8 to achieve intermittent material pushing.

[0050] One end of the rolling cloth 31 is fixed to one end of the rolling bottom plate 10 through a front fixing block 321, and the other end of the rolling cloth 31 is fixed to the other end of the rolling bottom plate 10 through a rear fixing block 322. The rolling cloth 31 is also located above the heating bottom plate 41. The rolling cloth 31 is used for placing the tape 8. The rolling cloth 31 is friction-resistant, high-temperature-resistant, has good flexibility, and is tensile-resistant.

The cloth turning bottom plate 682 is slidably installed on the coiled round bottom plate 10 through a linear guide pair, and is located at the other end of the heating bottom plate 41 and is connected to the coiling driving device 681. The coiling driving device 681 can adopt a coiling driving cylinder or a coiling driving linear guide pair, which is used to drive the cloth turning device to move. The coiling driving cylinder is installed at the bottom of the coiled round bottom plate 10, and the piston rod of the coiling cylinder is connected to the cloth turning bottom plate 682. One end of the cloth turning rod 673 is hinged to the cloth turning bottom plate 682 through a cloth turning rotating seat 674, and the other end is connected to the cloth turning roller 672 and is symmetrically located at both ends of the cloth turning roller 672; one end of the cloth turning cylinder 671 is hinged to the cloth turning rod 673, and the other end is hinged to the cloth turning bottom plate 682.

[0052] The cloth turning roller 672 facilitates the pushing of the coiled round cloth 31 and the tape 8 to be wound around the coiled round rod 64, ensuring the reliability of coiling.

[0053] When the piston rod of the cloth turning cylinder 671 extends, the cloth turning roller 672 drives one end of the tape 8 to be wound around the coiled round rod 64. When the piston rod of the cloth turning cylinder 671 retracts, the cloth turning roller 672 drives the coiled round cloth 31 to leave the rubber ring and the coiled round rod 64.

[0054] The rod changing device includes a rod changing reducer 62, a rod changing motor 61, and a front rod changing disc 631; the rod changing reducer 62 is installed on the cloth turning bottom plate 682, and the rod changing motor 61 is connected to the rod changing reducer 62; the front rod changing disc 631 is disc-shaped, the center of the front rod changing disc 631 is fixed on the rod changing reducer 62, the coiled round rod 64 is installed on the front rod changing disc 631, and the coiled round rods 64 are arranged in a circular array. The rod changing device drives the coiled round rod 64 to rotate, so that the coiled round rod 64 works in sequence. The rubber rings for coiling are just cooled and shaped, and the shaped rubber rings are then taken off by the blanking device, ensuring the qualified rate of rubber ring forming, improving the product quality, and the cooled rubber rings can effectively prevent the rubber rings from deforming. The rod changing device ensures continuous coiling.

[0055] Among them, the coiled round rod 64 is rotatably installed on the front rod changing disc 631 through a coiled round bearing seat 633. The rotatable installation of the coiled round rod 64 can ensure the synchronous rotation of the tape 8 and the coiled round rod 64, prevent the tape 8 from not rotating, avoid producing defective products, and ensure the qualified rate and quality of the products.

[0056] To ensure the reliability and stability of curling, it further includes a rear replacement rod disc 632. The rear replacement rod disc 632 is arc-shaped and is fixed on the front replacement rod disc 631 through a second connecting column and is coaxial with the front replacement rod disc 631. The curling rod 64 is also connected to the rear replacement rod disc 632 through a curling bearing. The curling rod 64 improves the stability of the curling rod 64 through two curling bearing seats 633 and extends the service life of the curling bearing seats 633.

[0057] The blanking device includes a blanking slider 65, a blanking driving block 662, and a blanking driving component 661. The blanking slider 65 is circular. The blanking slider 65 is movably inserted on the curling rod 64 and is located on one side of the rear replacement rod disc 632. A circular blanking groove 651 is provided on the blanking slider 65. The blanking groove 651 is arranged opposite to the blanking driving block 662, facilitating the blanking driving block 662 to be inserted into the blanking groove 651. The blanking driving component 661 can adopt a cylinder or a linear module. For the sake of compact structure, the blanking driving component 661 adopts a rodless cylinder. The rodless cylinder is installed on the cloth-turning bottom plate 682 through a blanking frame 663. The blanking driving block 662 is fixed on the cylinder slide of the rodless cylinder and is used to remove the rubber ring on the curling rod 64 through the blanking driving block 662 and the blanking groove 651. The overall structure is simpler, the blanking is convenient, and the blanking can be realized through one rodless cylinder. The blanking driving block 662 and the blanking groove 651 enable the blanking driving block 662 to reciprocate and do not affect the rotation of the curling rod 64 following the front replacement rod disc 631.

[0058] Among them, the blanking device is located behind the rod replacement device, enabling the rubber ring formed during curling to be cooled and shaped for the longest time, ensuring that the rubber ring during blanking will not deform. The curling rod 64 on the front replacement rod disc 631 curls in sequence and rotates towards the blanking device.

[0059] The tensioning device includes a tensioning roller 332, a transition roller 34, and a tensioning cylinder 331. The tensioning cylinder 331 is fixed on the curling bottom plate 10 and is located on one side of the rear fixing block 322. The tensioning cylinder 331 adopts a double-axis cylinder. The tensioning roller 332 is installed on the piston rod of the tensioning cylinder 331. The transition roller 34 is located between the cloth-turning bottom plate 682 and the tensioning cylinder 331. The curling cloth 31 enters below the tensioning roller 332 through the transition roller 34 and is then fixed on the rear fixing block 322. The tensioning device is used to tension the curling cloth 31 during curling by the cloth-turning device. When the tensioning device tensions the curling cloth 31, it can prevent the curling cloth 31 from being in a loose state when the cloth-turning device drives the tape 8 to wind around the curling rod 64, avoiding the tape 8 being unable to wind around the curling, and improving the reliability and stability of curling.

[0060] During curling, the tensioning cylinder 331 is in the retracted state, and the tensioning roller 332 tensions the curling cloth 31, ensuring that the curling cloth 31 can drive the tape 8 to be pressed against the curling rod 64 during curling. After curling is completed, before the cloth-flipping cylinder 671 retracts, the tensioning cylinder 331 extends, putting the curling cloth 31 in a free state, and then the cloth-flipping roller 672 flips to the rear.

[0061] During curling, the cloth-flipping roller 672 drives the curling cloth 31 to wrap around the curling rod 64. At this time, the cloth-flipping roller 672 is located at the curling ring 315 of the curling cloth 31, and a curling groove 311 is formed below the curling ring 315. Both the tape 8 and the curling rod 64 are located in the curling groove 311. The transition roller 34 abuts against the transition ring 313 of the curling cloth 31, and the tensioning roller 332 is pressed tightly in the tensioning groove 312 of the curling cloth 31.

[0062] First, the tape 8 is heated by the heating block 42 to make it soft, and then the tape 8 is pushed to directly below the curling rod 64 by the material transfer device, and the tape 8 is parallel to the curling rod 64. Then, the tape 8 is driven by the cloth-flipping device and the curling cloth 31 to wind around the curling rod 64. At this time, the end of the tape 8 is wrapped around the curling rod 64 to form a semi-circle. Then, the curling drive device 681 drives the curling rod 64, the cloth-flipping device, and the tape 8 to move on the heating bottom plate 41, and it moves towards the other end of the heating bottom plate 41. The rubber ring is completely wound around the curling rod 64 under the drive of the curling cloth 31 to form a rubber ring, realizing the automatic production of the rubber ring, greatly improving the curling efficiency, and reducing the curling cost.

The flattening rod 23 is located directly above the heating block 42 and at one end of the heating plate 4. The flattening device 2 presses the tape 8 tightly on the heating plate 4, which can not only improve the heating efficiency, quickly soften the tape 8, but also shape the tape 8 to keep the tape 8 in a flat state, facilitating subsequent curling and ensuring the quality of curling.

[0070] When feeding, the pulling cylinder 131 first retracts to expose the end of the tape 8 from the cutting groove 1331. Then, the feeding linear module 15 drives the feeding gripper 14 to move to the end of the tape 8. The feeding gripper 14 clamps the end of the tape 8. Then, the feeding linear module 15 moves in the direction away from the cutting device and stops when it reaches the set position. Then, the pulling cylinder 131 extends. Next, the upper cutting cylinder 138 drives the upper cutter 136 to descend, and the upper cutter 136 and the lower cutter 134 cut the tape 8. At this time, the length of the cut tape 8 is the set length. Then, the feeding gripper 14 releases the end of the tape 8. Next, the flattening cylinder 22 drives the flattening rod 23 to press the tape 8 tightly against the heating block 42 for heating and shaping.

[0071] At this time, in order to improve efficiency and prevent interference between the feeding device and the material transfer device, the material transfer device further includes a fixed material transfer rod 58.

It automatically collects rubber rings, which is convenient for transportation and can also reduce the workload of subsequent packaging, improving the overall efficiency.

[0075] Specifically, the collecting device 7 includes a collecting hopper 78, a collecting rack, a collecting cartridge 73 and a cartridge moving assembly. The collecting rack includes a collecting bottom plate 711 and a baffle plate 712. The baffle plate 712 is fixed on both sides of the collecting bottom plate 711 to restrict the collecting cartridge 73 on the collecting rack. The collecting bottom plate 711 is located on one side of the coiling bottom plate 10. One end of the collecting bottom plate 711 is equipped with a cartridge rack 713, and the collecting cartridges 73 are stacked movably in the cartridge rack 713. The cartridge moving assembly includes a cartridge moving cylinder 741 and a cartridge moving plate 742. The cartridge moving cylinder 741 is fixed on the collecting bottom plate 711 and is a double-axis cylinder. The cartridge moving plate 742 is fixed on the cartridge moving cylinder 741. The cartridge moving plate 742 is L-shaped and is movably inserted into a material receiving hole on the collecting bottom plate 711. The material receiving hole is smaller than the collecting cartridge 73. The flat plate 7422 of the cartridge moving plate 742 is located at the bottom of the collecting cartridge 73 for supporting the collecting cartridge 73 and can avoid scratching the bottom of the collecting cartridge 73. The collecting hopper 78 is installed on the blanking rack 663, is located above the collecting bottom plate 711, and is also located on one side of the cartridge rack 713.

[0076] When collecting rubber rings, the cartridge moving cylinder 741 extends, the cartridge moving plate 742 leaves the bottom of the collecting cartridge 73 and moves to one side of the collecting cartridge 73. The collecting cartridge 73 drops onto the collecting bottom plate 711 under the action of gravity. Then the cartridge moving cylinder 741 drives the cartridge moving plate 742 to retract. The cartridge moving plate 742 drives the lowermost collecting cartridge 73 to move under the collecting hopper 78. Then the flat plate 7422 of the cartridge moving plate 742 supports the collecting cartridge 73. The flat plate 7422 is located at the middle of the height of the collecting cartridge 73, so that the collecting cartridges 73 in the cartridge rack 713 slide down in two times to reduce the impact.
