Description

Technical Field

[0001] The invention relates to the field of unwinding equipment, in particular to a self-adaptively adjustable polyester belt unwinding mechanism. Background Art

[0002] Polyester tape is usually used in the form of a roll. When in use, a rotating shaft is passed through the middle, and the polyester tape can be released outward by rotating the rotating shaft. There are some problems with this solution when in use. Specifically, the outer diameter of the polyester tape roll will become smaller and smaller as the material is discharged. If the rotation speed of the rotating shaft is consistent, the discharge speed will become slower and slower, and the material cannot be fed stably. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a self-adjustable polyester tape unwinding mechanism. The supporting roller of the present invention is in contact with the polyester tape roll surface, the supporting roller drives the polyester tape roll to rotate, and the polyester tape roll is in contact with the supporting roller. As long as the rotation speed of the supporting roller is consistent, the outer surface linear speed of the polyester tape roll can be ensured to remain stable, so as to achieve the purpose of stable material discharge.

[0004] The technical solution adopted by the present invention to solve the technical problem is: a self-adjustable polyester belt unwinding mechanism, comprising a feeding unit and a traction unit;

[0005] The feeding unit comprises a lifting shaft, a guide column and a supporting roller;

[0006] The lifting shaft is horizontally arranged, and is used to support the polyester tape roll. The two ends of the lifting shaft are respectively rotatably matched with the sliders, and the two corresponding sliders are respectively provided with guide columns, and the guide columns are vertically arranged, and the side walls of the guide columns are provided with slide rails for the sliders to slide and match;

[0007] Two supporting rollers are arranged in parallel on both sides of the lower part of the guide column, and the supporting rollers are driven by a motor;

[0008] The traction unit comprises two annular conveyor belt wheel assemblies, which are arranged in parallel through a bracket, and the polyester belt is drawn out from the polyester belt roll and passes between the two annular conveyor belt wheel assemblies.

[0009] When in use, the feeding unit is used to store the polyester tape roll and feed it externally, and the traction unit is used to pull the polyester tape roll output by the feeding unit outward so that the polyester tape can be more easily output externally.

[0010] The guide column and the slider are used to guide the lifting and lowering of the lifting shaft so that the lifting shaft can move up and down stably, so that the polyester tape roll is always kept between the guide columns and is always supported by the supporting roller below. Since the slider can slide relative to the slide rail, no matter how large the diameter of the polyester tape roll is, the polyester tape roll can always be placed on the supporting roller, and the supporting roller can always provide support for the polyester tape roll. The power for the rotation of the polyester tape roll comes from the supporting roller, and the rotation of the supporting roller drives the polyester tape roll to rotate. As long as the rotation speed of the supporting roller is consistent, the linear speed of the outer surface of the polyester tape roll can be kept consistent during the discharge process, and the external feeding can be more stable.

[0011] Preferably, only one of the supporting rollers is driven by a motor, so as to better control the outer surface linear speed of the polyester tape roll.

[0012] Preferably, the slide rail is configured as a slide groove, so as to better match the slide block.

[0013] Preferably, the slide groove is an inverted T-shaped slide groove, which can maintain stable cooperation between the slider and the slide groove.

[0014] Preferably, the endless conveyor belt wheel assembly comprises a frame, a traction wheel and an endless conveyor belt;

[0015] A traction wheel is respectively arranged at both ends of the frame, and the annular conveyor belt is respectively wound around and adapted to the two traction wheels;

[0016] The outer surfaces of the two endless conveyor belts are in contact.

[0017] Using an endless conveyor belt to pull the polyester belt can increase the friction with the polyester belt and pull the polyester belt more stably. At the same time, it can reduce the pressure on the polyester belt and avoid irreversible damage to the polyester belt.

[0018] Preferably, the frame is provided with a plurality of retaining wheels, the retaining wheels are adapted to the inner surface of the endless belt, the retaining wheels are located on the inner side of the two endless conveyor belt wheel assemblies, and the retaining wheels of the two endless conveyor belt wheel assemblies are distributed one by one. The retaining wheels can enable the endless conveyor belt between the two traction wheels to continuously provide pressure to the polyester belt so as to increase the friction.

[0019] Preferably, the first annular conveyor pulley assembly is fixed to the frame, the second annular conveyor pulley assembly is movably arranged on the frame, and the second annular conveyor pulley assembly is pushed by an elastic member to be close to the first annular conveyor pulley assembly. The second annular conveyor pulley assembly is brought closer to the first annular conveyor pulley assembly by the elastic member, and the pre-tightening force of the two can be included to avoid the problem of insufficient traction due to looseness.

[0020] Preferably, the frame is provided with a slide bar, and the slide bar is slidably matched with a slide cylinder, the middle part of the skeleton of the second annular conveyor pulley assembly is hinged to the slide cylinder, the elastic member is a spring, the spring is sleeved on the slide bar, the slide bar is equipped with a pre-tightening nut, and the two ends of the spring are respectively against the pre-tightening nut and the skeleton. The slide cylinder is pushed by the spring so that the slide cylinder approaches the first traveling conveyor pulley assembly. Since the second annular conveyor pulley assembly is hinged to the slide cylinder, the second annular conveyor pulley assembly will approach the first annular conveyor pulley assembly to provide pre-tightening pressure on the polyester belt between the two annular conveyor pulley assemblies, and since it is hinged to the slide cylinder, it can well maintain a balanced state of pressure between the two ends of the annular conveyor pulley assembly to avoid high pressure at one end and low pressure at the other end.

[0021] Preferably, a buffer unit is provided between the feeding unit and the traction unit, and the buffer unit comprises a turntable driven by a servo motor, and the turntable surface is provided with at least two groups of guide rollers, and the guide rollers of the same group are arranged in parallel, and the guide rollers rotate relative to the turntable, and the polyester belt passes through between the guide rollers of each group. When the traction speed of the traction unit is less than the discharging speed of the feeding unit, the turntable is rotated to bend the polyester belt, thereby making it retain more polyester belts, avoiding the disorderly accumulation of polyester belts, and achieving the effect of buffering. When the discharging speed of the feeding unit is less than the traction speed of the traction unit, the turntable is rotated in the opposite direction to release the buffered polyester belt, which can play a role in balancing the speed of the units on both sides for a period of time.

[0022] Preferably, the outer surface of the endless conveyor belt is covered with a foam layer, which can improve the friction force on the one hand and make it softer on the other hand to avoid crushing the polyester belt.

[0023] Advantages of the present invention:

[0024] The present invention provides support for the polyester tape roll by a supporting roller, and the two are in surface contact. The supporting roller drives the polyester tape roll to rotate during its rotation, and the polyester tape roll is arranged on a lifting shaft, so it can always be in contact with the supporting roller. As long as the rotation speed of the supporting roller is consistent, the outer surface linear speed of the polyester tape roll can be ensured to remain stable, so as to achieve the purpose of stable material discharge. In addition, an endless conveyor belt is used to pull the polyester tape roll, which can increase friction while reducing pressure on the polyester tape, thereby avoiding irreversible damage to the polyester tape.

DETAILED DESCRIPTION

[0031] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.

[0032] Example

[0033] like Figure 1 As shown, a self-adaptive polyester tape unwinding mechanism comprises a feeding unit 1 and a traction unit 11; the feeding unit 1 comprises a lifting shaft 6, a guide column 3 and a supporting roller 7; the lifting shaft 6 is horizontally arranged, and the lifting shaft 6 is used to support the polyester tape roll 2, and the two ends of the lifting shaft 6 are respectively rotatably matched with the slider 5, and the corresponding two sliders 5 are respectively provided with guide columns 3, the guide columns 3 are vertically arranged, and the side walls of the guide columns 3 are provided with slide rails 4 for the sliding cooperation of the slider 5; two sides of the lower part of the guide column 3 are arranged side by side with two supporting rollers 7, and the supporting rollers 7 are driven by a motor; the traction unit 11 comprises two annular conveyor belt 14 wheel assemblies, and the two annular conveyor belt 14 wheel assemblies are arranged side by side through a bracket, and the polyester tape is led out from the polyester tape roll 2 and passes between the two annular conveyor belt 14 wheel assemblies.

[0034] When in use, the feeding unit 1 is used to store the polyester tape roll 2 and feed it to the outside, and the traction unit 11 is used to pull the polyester tape roll 2 output by the feeding unit 1 outward so that the polyester tape can be more easily output to the outside.

[0035] The guide column 3 and the slider 5 are used to guide the lifting and lowering of the lifting shaft 6 so that the lifting shaft 6 can move up and down stably, so that the polyester tape roll 2 is always kept between the guide columns 3, and the bottom is always supported by the support roller 7. Since the slider 5 can slide relative to the slide rail 4, no matter how large the diameter of the polyester tape roll 2 is, the polyester tape roll 2 can always be placed on the support roller 7, and the support roller 7 can always provide support for the polyester tape roll 2. The power for the rotation of the polyester tape roll 2 comes from the support roller 7. The rotation of the support roller 7 drives the polyester tape roll 2 to rotate. As long as the rotation speed of the support roller 7 is consistent, the linear speed of the outer surface of the polyester tape roll 2 can be kept consistent during the discharge process, and the external feeding can be more stable.

[0036] Only one of the supporting rollers 7 is driven by a motor so as to better control the outer surface linear speed of the polyester tape roll 2.

[0037] The slide rail 4 is configured as a slide groove, so as to be better adapted to the slide block 5 .

[0038] The slide groove is an inverted T-shaped slide groove, which can maintain stable cooperation between the slider 5 and the slide groove.

[0039] The wheel assembly of the endless conveyor belt 14 includes a frame 12, a traction wheel 13 and an endless conveyor belt 14;

[0040] A traction wheel 13 is respectively disposed at both ends of the frame 12, and the annular conveyor belt 14 is respectively wound around and adapted to the two traction wheels 13;

[0041] The outer surfaces of the two endless conveyor belts 14 are in contact.

[0042] The use of the endless conveyor belt 14 to pull the polyester belt can increase the friction with the polyester belt and pull the polyester belt more stably. At the same time, the pressure on the polyester belt can be reduced to avoid irreversible damage to the polyester belt.

[0043] The skeleton 12 is provided with a plurality of retaining wheels 15, which are adapted to the inner surface of the endless belt and are located on the inner side of the wheel assembly of the two endless conveyor belts 14. The retaining wheels 15 of the wheel assembly of the two endless conveyor belts 14 are distributed one by one. The retaining wheels 15 enable the endless conveyor belt 14 between the two traction wheels 13 to continuously provide pressure to the polyester belt so as to increase the friction.

[0044] The first wheel assembly of the circular conveyor belt 14 is fixed to the frame, and the second wheel assembly of the circular conveyor belt 14 is movably arranged on the frame, and the second wheel assembly of the circular conveyor belt 14 is pushed to be close to the first wheel assembly of the circular conveyor belt 14 by the elastic member 17. The second wheel assembly of the circular conveyor belt 14 is brought closer to the first wheel assembly of the circular conveyor belt 14 by the elastic member 17, and the pre-tightening force of the two can be included to avoid the problem of insufficient traction due to looseness.

[0045] The frame is provided with a slide bar 16, and the slide bar 16 is slidably matched with a slide cylinder 18. The middle part of the skeleton 12 of the second endless conveyor belt 14 wheel assembly is hinged to the slide cylinder 18. The elastic member 17 is a spring, and the spring is sleeved on the slide bar 16. The slide bar 16 is adapted to be equipped with a pre-tightening nut 19, and the two ends of the spring are respectively against the pre-tightening nut 19 and the skeleton 12. The slide cylinder 18 is pushed by the spring so that the slide cylinder 18 approaches the first traveling conveyor belt wheel assembly. Since the second endless conveyor belt 14 wheel assembly is hinged to the slide cylinder 18, the second endless conveyor belt 14 wheel assembly will approach the first endless conveyor belt 14 wheel assembly to provide pre-tightening pressure on the polyester belt between the two endless conveyor belt 14 wheel assemblies. And since it is hinged to the slide cylinder 18, it can well include the pressure between the two ends of the endless conveyor belt 14 wheel assembly to maintain a balanced state, avoiding high pressure at one end and low pressure at the other end.

[0046] A buffer unit is provided between the feeding unit 1 and the traction unit 11. The buffer unit includes a turntable 9 driven by a servo motor. The turntable 9 is provided with at least two groups of guide rollers 10. The guide rollers 10 of the same group are arranged in parallel. The guide rollers 10 rotate relative to the turntable 9, and the polyester belt passes between each group of guide rollers 10. When the traction speed of the traction unit 11 is less than the discharging speed of the feeding unit 1, the turntable 9 is rotated to bend the polyester belt, thereby allowing more polyester belt to stay on it, avoiding the disorderly accumulation of the polyester belt, and achieving the effect of buffering. When the discharging speed of the feeding unit 1 is less than the traction speed of the traction unit 11, the turntable 9 is rotated in the opposite direction to release the buffered polyester belt, which can neutralize the speed of the units on both sides for a period of time.

[0047] The outer surface of the endless conveyor belt 14 is covered with a foam layer, which can improve the friction force on the one hand and make it softer on the other hand to avoid crushing the polyester belt.

[0048] Advantages of the present invention:

[0049] The present invention provides support for the polyester tape roll 2 through a supporting roller 7, and the two are in surface contact. The supporting roller 7 drives the polyester tape roll 2 to rotate during its rotation, and the polyester tape roll 2 is arranged on the lifting shaft 6, so it can always be in contact with the supporting roller 7. As long as the rotation speed of the supporting roller 7 is consistent, the outer surface linear speed of the polyester tape roll 2 can be ensured to remain stable, so as to achieve the purpose of stable discharging. In addition, the polyester tape roll 2 is pulled by an annular conveyor belt 14, which can increase the friction while reducing the pressure on the polyester tape, thereby avoiding irreversible damage to the polyester tape.
